Alternatively, the vehicle 1000 may also have a tailgate (not shown), and a step bar apparatus 100 for a vehicle adjacent to the tailgate is provided at the rear of the vehicle body 200.

A step bar apparatus for a vehicle according to an embodiment of the present invention is described below.

As shown in fig. 4, a vehicle step bar apparatus 100 according to an embodiment of the present invention includes a step bar 1, a telescopic device 2, and a locking member 3, wherein the step bar 1 is movable between an extended position and a retracted position.

The telescopic device 2 comprises a mounting support 21, a pedal support 22 and an arm assembly 23. The pedal lever 1 is mounted on a pedal lever support 22, and an arm assembly 23 is pivotally connected to the mounting support 21 and the pedal lever support 22, respectively, to drive the pedal lever 1 between the extended position and the retracted position. In other words, arm assembly 23 is pivotally connected at one end to mounting bracket 21 and at the other end to bar bracket 22, and arm assembly 23 is driven by a drive means, such as a motor, to move bar 1 between the extended and retracted positions. Specifically, the mount bracket 21 may be mounted on the bottom surface 201 of the vehicle body 200.

The locking member 3 is engageable with and disengageable from one of the pedal lever 1 and the pedal lever support 22, wherein in the retracted position, the locking member 3 engages one of the pedal lever 1 and the pedal lever support 22 to lock the pedal lever 1 in the retracted position. In one embodiment, the locking member 3 directly engages with the pedal lever 1 and disengages from the pedal lever 1, and specifically, when the pedal lever 1 is moved to the retracted position, the locking member 3 engages the pedal lever 1 to lock the pedal lever 1 in the retracted position, and the locking member 3 disengages from the pedal lever 1 to allow the pedal lever 1 to move from the retracted position toward the extended position. In another embodiment, the pedal lever 1 is mounted on the pedal lever support 22, the locking member 3 is engaged with and disengaged from the pedal lever support 22 to effect locking and releasing of the locking member 3 to the pedal lever 1 to lock the pedal lever 1 in the retracted position by engaging the pedal lever support 22, and the locking member 3 is disengaged from the pedal lever support 22 to allow the pedal lever support 22 to move the pedal lever 1 from the retracted position toward the extended position.

Here, it is to be understood that the lock member 3 may release the pedal lever 1 or the pedal lever support 22 before the pedal lever 1 leaves the retracted position, or may release the pedal lever 1 or the pedal lever support 22 simultaneously with the pedal lever 1 leaving the retracted position, that is, the process of disengaging the pedal lever 1 or the pedal lever support 22 from the lock member 3 may be performed simultaneously with the process of leaving the pedal lever 1 from the retracted position.

In some embodiments, in the retracted position, the pedal lever 1 abuts against the lower edge of the side of the body 200. For example, the pedal 1 is oriented in the vertical direction and rests against the lower edge of the side of the vehicle body 200, so that the pedal 1 covers the lower edge of the vehicle body 200.

In other embodiments, in the retracted position, the pedal lever 1 is obliquely abutted against the intersection of the bottom surface 201 of the vehicle body 200 and the side surface of the vehicle body 200. In other words, the step bar 1 is disposed obliquely with respect to the side surface of the vehicle body 200 and abuts on the boundary between the bottom surface 201 of the vehicle body and the side surface of the vehicle body 200, whereby the step bar 1 can cover the outer edge of the bottom surface 201 of the vehicle body and the lower edge of the side surface of the vehicle body 200. Thus, by locking the step bar 1 at the retracted position by the locking member 3, the step bar 1 can function as a bumper of the vehicle to serve a protection function to protect the vehicle body from being hit or scraped.

In some embodiments, one of the pedal lever 1 and the pedal lever support 22 is disengaged from the locking member 3 against the locking force of the locking member 3 when the pedal lever 1 is moved from the retracted position toward the extended position.

In some embodiments, one of the pedal lever 1 and the pedal lever support 22 has an engaging member 4, and the locking member 3 is engageable and disengageable from the engaging member 4. In other words, the pedal lever 1 has the engaging member 4, or the pedal lever support 22 has the engaging member 4, and the locking member 3 is engageable with the engaging member 4 to lock the pedal lever 1 in the retracted position when the pedal lever 1 is moved to the retracted position, and the locking member 3 and the engaging member 4 are disengaged, i.e., the locking member 3 releases the pedal lever 1, when the pedal lever 1 is moved from the retracted position toward the extended position, so that the pedal lever 1 can be moved from the retracted position toward the extended position.

When the door 300 is opened, the locking member 3 is disengaged from the engagement member 4, and the telescopic device 2 drives the foot bar 1 to move to the extended position, as shown in fig. 1, so that a person can get on the vehicle through the foot bar 1. As shown in fig. 2, when the vehicle door 300 is closed, the retractor 2 drives the pedal lever 1 to move to the retracted position, and when the pedal lever 1 moves to the retracted position, the locking member 3 engages with the engaging member 4 to lock the pedal lever 1. It will be appreciated that in some embodiments the locking member 3 engages with the engagement member 4 to lock the foot bar 1 after the foot bar 1 is moved to the retracted position, and in other embodiments the foot bar 1 gradually enters a position locked by the locking member 3 at the same time as the foot bar 1 moves towards the retracted position and the locking member 3 completes the locking of the foot bar 1 as the foot bar 1 moves to the retracted position.

In some embodiments, the manner of attaching the engaging member 4 to the pedal 1 or the pedal support 22 is not limited, and for example, the engaging member 4 may be detachably attached to the pedal 1 or the pedal support 22, or the engaging member 4 may be integrally formed with the pedal 1 or the pedal support 22. For example, as shown in fig. 4, the engaging member 4 is provided on the tread bar 1, and the engaging member 4 is formed integrally with the tread bar 1. Wherein the engaging member 4 and the pedal lever 1 can be regarded as separate members different from each other when the engaging member 4 is detachably attached to the pedal lever 1, and the engaging member 4 and the pedal lever 1 can be regarded as one body when the engaging member 4 is formed integrally with the pedal lever 1.

In some specific examples, as shown in fig. 4-8, the engagement member 4 includes an engagement shaft 41 and the locking member 3 includes a locking seat 31. The lock holder 31 has a lock groove 312, and the engagement shaft 41 is engageable in the lock groove 312 and disengageable from the lock groove 312.

Specifically, the pedal lever 1 is locked in the retracted position by the retaining force of the locking groove 312 to the engaging shaft 41, wherein the engaging shaft 41 is disengaged from the locking groove 312 against the retaining force of the locking groove 312 when the pedal lever 1 moves from the retracted position toward the extended position.

In other words, when the pedal lever 1 is moved to the retracted position, as shown in fig. 6, 8, the engagement shaft 41 of the engagement member 4 is engaged in the locking groove 312 on the lock holder 31, and the pedal lever 1 is locked in the retracted position by the retaining force of the locking groove 312 to the engagement shaft 41. When it is desired to move the pedal lever 1 from the retracted position toward the extended position, the engaging shaft 41 is disengaged from the locking groove 312 against the locking force of the locking groove 312 to allow the pedal lever 1 to move from the retracted position toward the extended position, thereby facilitating the movement of the pedal lever 1 to the extended position, as shown in fig. 5, 7. It is understood that, when the pedal lever 1 is moved toward the retracted position, the engaging shaft 41 starts to enter the locking groove 312 when the pedal lever 1 is moved to a predetermined position, the engaging shaft 41 gradually enters the locking groove 312 as the pedal lever 1 is further moved toward the retracted position, and when the pedal lever 1 is moved to the retracted position, the engaging shaft 41 is entirely entered into the locking groove 312, that is, the engaging shaft 41 is completely engaged in the locking groove 312, to achieve the locking of the pedal lever 1. On the contrary, when the pedal lever 1 is gradually moved from the retracted position toward the protruding position, the engaging shaft 41 gradually comes out from the locking groove 312, and when the pedal lever 1 is moved from the retracted position to the predetermined position, the engaging shaft 41 is all out of the locking groove 312, thereby releasing the pedal lever 1.

In some embodiments, the engagement member 4 further includes a first support ear 42 and a second support ear 43, the first support ear 42 and the second support ear 43 being spaced apart from each other, a first end of the engagement shaft 41 being connected to the first support ear 42, a second end of the engagement shaft 41 being connected to the second support ear 43, the first support ear 42 and the second support ear 43 being spaced apart from each other on the pedal 1 when the engagement member 4 is disposed on the pedal 1, and the first support ear 42 and the second support ear 43 being spaced apart from each other on the pedal support 22 when the engagement member 4 is disposed on the pedal support 22.

As shown in fig. 4, since the extension arm portion 311 extends downward from the bottom of the lock seat 31, the free end surface of the extension arm portion 311 is the lower end surface of the extension arm portion 311, that is, the lock groove 312 is provided on the lower end surface of the extension arm portion 311.

In some preferred embodiments, the outer circumferential profile of the cross-section of the engagement shaft 41 is adapted to the inner circumferential profile of the locking groove 312 to better engage the engagement shaft 41 within the locking groove 312. Specifically, the cross section of the engaging shaft 41 is non-circular, and the inner peripheral profile of the locking groove 312 is also non-circular, for example, polygonal such as quadrangle, hexagon, etc., wherein fig. 4 to 6 show that the outer peripheral profile of the engaging shaft 41 and the inner peripheral profile of the locking groove 312 are regular hexagons, and fig. 7 to 8 show that the outer peripheral profile of the engaging shaft 41 and the inner peripheral profile of the locking groove 312 are trapezoidal. It is to be understood that the cross section of the engagement shaft 41 is not limited thereto.

In some embodiments, the locking seat 31 is coupled to the mounting bracket 21. In other words, the lock seat 31 can be regarded as a different member from the mount bracket 21. In other embodiments, the locking seat 31 is integrally formed with the mounting bracket 21. In other words, the locking seat 31 and the mounting seat 21 may be regarded as one integral component.

Specifically, as shown in fig. 4 to 6, the mount base 21 and the lock base 31 are connected in series in the left-right direction and are provided on the bottom surface 201 of the vehicle body 200, the lower end of the mount base 21 is pivotably connected to the upper end of the arm assembly 23, the lower end of the arm assembly 23 is pivotably connected to the upper end of the pedal lever support 22, and the pedal lever 1 is provided on the lower end of the pedal lever support 22.

A step bar apparatus for a vehicle according to some embodiments of the present invention will be described below.

As shown in fig. 1 to 4, a vehicle step bar apparatus 100 according to an embodiment of the present invention includes a step bar 1, a telescopic device 2, and a locking member 3. The telescopic device 2 comprises a pedal lever support 22 on which the pedal lever 1 is mounted, and an arm assembly 23 pivotally connected to the pedal lever support 22 and adapted to be pivotally connected to the underside of the body 200 of the vehicle 1000 to drive the pedal lever 1 between the extended position and the retracted position. In other words, one end of the arm assembly 23 is adapted to be pivotally connected to the bottom surface 201 of the body 200 of the vehicle 1000, the other end of the arm assembly 23 is pivotally connected to the pedal support 22, and the arm assembly 23 is driven by a driving means such as a motor to move the pedal 1 between the extended position and the retracted position.

A lock member 3 is mounted on the bottom surface 201 of the vehicle body 200, the lock member 3 is engageable with and disengageable from one of the pedal lever 1 and the pedal lever support 22, in the retracted position, the lock member 3 is engaged with one of the pedal lever 1 and the pedal lever support 22 to lock the pedal lever 1 in the retracted position, and the lock member 3 is disengaged from one of the pedal lever 1 and the pedal lever support 22 when the pedal lever 1 is moved from the retracted position toward the extended position.

A vehicle step bar apparatus and a vehicle according to some embodiments of the present invention will be described with reference to fig. 1 to 3 and fig. 13 to 20.

As shown in fig. 13 to 15, a vehicle step bar apparatus 100 according to an embodiment of the present invention includes a step bar 1, a telescopic device 2, a locking seat 31, and a locking swing arm 32, wherein the step bar 1 is movable between an extended position and a retracted position.

The lock swing arm 32 is swingable between a lock position where the lock swing arm 32 and the lock seat 31 lock the pedal lever 1 in the retracted position and a release position; in the release position, the lock swing arm 32 and the lock seat 31 release the pedal lever 1 so that the pedal lever 1 can move from the retracted position toward the extended position.

In some embodiments, the locking swing arm 32 rotates from the locking position to the releasing position before the foot bar 1 moves away from the retracted position toward the extended position. In other words, before the pedal lever 1 needs to be moved from the retracted position toward the extended position, the locking swing arm 32 is first rotated from the locking position to the releasing position to release the engagement member 4, so that the arm assembly 23 moves the pedal lever 1 from the retracted position shown in fig. 18 to the extended position shown in fig. 16.

In some embodiments, the release position includes a maximum release position and a minimum release position, the minimum release position being located between the lock position and the maximum release position. Specifically, as shown in fig. 18, the pedal lever 1 is in the retracted position, the lock swing arm 32 is in the lock position, and the lock swing arm 32 and the lock seat 31 sandwich the joint member 4 between the lock swing arm 32 and the lock seat 31 to lock the pedal lever 1. As shown in fig. 17, the lock swing arm 32 is rotated rightward from the lock position to the minimum release position, the engaging member 4 is released from the grip of the lock swing arm 32 and the lock base 31, that is, the engaging member 4 is released, and the pedal lever 1 is moved to an intermediate position between the extended position and the retracted position. Subsequently, as shown in fig. 16, the lock swing arm 32 continues to rotate rightward from the minimum release position to the maximum release position, and the pedal lever 1 moves from the intermediate position to the extended position.

The interrelationship between the rotation of the locking swing arm 32 and the telescopic movement of the arm assembly 23 is:

in some embodiments, the locking swing arm 32 rotates from the locking position to the minimum release position before the pedal lever 1 moves away from the retracted position toward the extended position, and the pedal lever 1 moves from the retracted position to the extended position while the locking swing arm rotates from the minimum release position to the maximum release position.

In some embodiments, the pedal lever 1 further has an intermediate position between the retracted position and the extended position, the locking swing arm 32 rotates from the locking position to the minimum release position before the pedal lever 1 moves away from the retracted position toward the extended position, wherein the pedal lever 1 moves from the retracted position to the intermediate position while the locking swing arm 32 rotates from the minimum release position to the maximum release position, wherein the locking swing arm 32 is stationary at the maximum release position during the movement of the pedal lever 1 from the intermediate position to the extended position.

It will be appreciated that, in addition to the movement of the locking swing arm 32 and the pedal lever 1, it is also possible to first lock the swing arm 32 to rotate from the locking position to the minimum release position.

Next, the pedal lever 1 is moved from the retracted position to the intermediate position, that is, the locking swing arm 32 is rotated to the minimum release position and then stays there for a period of time during which the pedal lever 1 is moved from the retracted position to the intermediate position, and at the end of the period of time, the pedal lever 1 is at the intermediate position between the extended position and the retracted position, and the locking swing arm 32 is at the minimum release position between the maximum release position and the locking position, as shown in fig. 17, for example.

Thirdly, the pedal lever 1 moves from the middle position to the extended position, and the locking swing arm 32 rotates from the minimum release position to the maximum release position, in the process, the movement of the pedal lever 1 and the rotation of the locking swing arm 32 can be carried out simultaneously, the pedal lever 1 can move firstly, the locking swing arm 32 rotates secondly, the locking swing arm 32 can rotate firstly, and the pedal lever 1 moves secondly.

In some embodiments, the foot bar 1 abuts against the lower edge of the side of the vehicle body 200 in the retracted position, e.g. the foot bar 1 is oriented in the vertical direction and abuts against the lower edge of the side of the vehicle body 200, whereby the foot bar 1 covers the lower edge of the vehicle body 200. In other embodiments, the step bar 1 is obliquely attached to the boundary between the bottom surface 201 of the vehicle body and the side surface of the vehicle body 200, in other words, the step bar 1 is obliquely disposed with respect to the side surface of the vehicle body 200 and attached to the boundary between the bottom surface 201 of the vehicle body and the side surface of the vehicle body 200, so that the step bar 1 covers the outer edge of the bottom surface 201 of the vehicle body and the lower edge of the side surface of the vehicle body 200. Thus, by locking the step bar 1 at the retracted position by the locking member 3, the step bar 1 can function as a bumper of the vehicle to serve a protection function to protect the vehicle body from being hit or scraped.

In some embodiments, one of the pedal lever 1 and the pedal lever support 22 has the engagement member 4, and in the retracted position, the locking swing arm 32 and the locking seat 32 sandwich the engagement member 4 therebetween to lock the pedal lever 1. In other words, the pedal lever 1 has the engaging member 4, or the pedal lever support 22 has the engaging member 4, and when the pedal lever 1 is moved to the retracted position, the engaging member 4 can be held by the locking swing arm 32 and the locking seat 31, thereby achieving the locking of the pedal lever 1.

In some embodiments, the manner of attaching the engaging member 4 to the pedal 1 or the pedal support 22 is not limited, and for example, the engaging member 4 may be detachably attached to the pedal 1 or the pedal support 22, or the engaging member 4 may be integrally formed with the pedal 1 or the pedal support 22. For example, as shown in fig. 13, the engaging member 4 is provided on the tread bar 1, and the engaging member 4 is formed integrally with the tread bar 1. Wherein the engaging member 4 and the pedal lever 1 can be regarded as separate members different from each other when the engaging member 4 is detachably attached to the pedal lever 1, and the engaging member 4 and the pedal lever 1 can be regarded as one body when the engaging member 4 is formed integrally with the pedal lever 1.

In some particular embodiments, as shown in figures 13-16, the engagement member 4 comprises an engagement shaft 41, in the retracted position the locking swing arm 32 and the locking seat 31 clamp the engagement shaft 41 between them to lock the pedal lever 1.

It is to be understood that the engaging member 4 is not limited to the form of the engaging shaft 41, and for example, as shown in fig. 9, the engaging member 4 is an engaging protrusion 401, and the engaging protrusion 401 may be clamped between the first card slot 313 and the second card slot 321, or released from between the first card slot 313 and the second card slot 321. In some embodiments, the engaging projection 401 is provided on the step bar 1, and may be provided on the step bar support 22. When the engaging projection 401 is provided on the step bar 1, the engaging projection 401 may be detachably attached to the step bar 1 or may be formed integrally with the step bar 1. When the engaging projection 401 is provided on the pedal support 22, the engaging projection 401 may be detachably attached to the pedal support 22 or may be formed integrally with the pedal support 22.

Wherein a first driven gear 52 is drivable by the driving gear 51 and connected to the arm assembly 23 and a second driven gear 53 is drivable by the driving gear 51 and connected to the locking swing arm 32. The drive motor 6 drives the arm assembly 23 through the drive gear 51 and the first driven gear 52 to move the pedal lever 1 between the extended position and the retracted position, and the drive motor 6 drives the lock swing arm 32 through the drive gear 51 and the second driven gear 53 to swing the lock swing arm 32 between the lock position and the release position. It will be appreciated that the second driven gear 53 drives the drive lever 33 to rotate to swing the locking swing arm 32 between the locked position and the released position.

In some alternative embodiments, as shown in fig. 24-31, the toothed segment 511 of the driving gear 51 alternately meshes with the first and second driven gears 52, 53 to alternately drive the first and second driven gears 52, 53 to rotate. In other words, the toothed section 511 of the driving gear 51 is not engaged with the first driven gear 52 and the second driven gear 53 at the same time, and is engaged with one driven gear only after being disengaged from the other driven gear.

In other alternative embodiments, as shown in fig. 24-26 and 32, the drive gear 51 has a first rotational position (the position of the drive gear 51 shown in fig. 24 and the a position shown in fig. 32), a second rotational position (the position of the drive gear shown in fig. 26 and the B position shown in fig. 32), and a third rotational position (the C position shown in fig. 32) between the first rotational position and the second rotational position, between which the drive gear 51 is reciprocally rotatable.

Wherein in the first rotational position, as shown in fig. 24, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53, and the toothless section 512 of the driving gear 511 is opposite to the first driven gear 52; in the second rotational position, as shown in fig. 26, the toothed section 511 of the driving gear 511 is engaged with the first driven gear 52 and the non-toothed section 512 of the driving gear 511 is opposed to the second driven gear 53.

Wherein the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the non-toothed section 512 of the driving gear 51 is opposed to the first driven gear 52 for driving the locking swing arm 32 to move from the locking position toward the releasing position before the driving gear 51 rotates in the first direction (counterclockwise direction in fig. 24 and 26) from the first rotational position to the third rotational position.

Wherein when the driving gear 51 rotates in the first direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to engage with the first driven gear 52 to start driving the pedal lever 1 to move from the retracted position toward the extended position. Wherein during the rotation of the driving gear 51 from the third rotational position to the second rotational position in the first direction, the toothed section 511 of the driving gear 51 is simultaneously engaged with the second driven gear 53 and the first driven gear 52 for driving the locking swing arm 32 to move toward the releasing position while driving the pedal lever 1 to move toward the extended position.

In still other alternative embodiments, as shown in fig. 24-26 and 33, the drive gear 51 has a first rotational position (the position of the drive gear 51 shown in fig. 24 and the a position shown in fig. 33), a second rotational position (the position of the drive gear shown in fig. 26 and the B position shown in fig. 33), a third rotational position (the C position shown in fig. 33) between the first rotational position and the second rotational position, and a fourth rotational position (the D position shown in fig. 33) between the third rotational position and the second rotational position, and the drive gear 51 is reciprocally rotatable between the first rotational position and the second rotational position.

Wherein the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the non-toothed section 512 of the driving gear 51 is opposite to the first driven gear 52 before the driving gear 51 rotates in the first direction (counterclockwise direction in fig. 24 and 26) from the first rotational position to the third rotational position to drive the locking swing arm 32 to move from the locking position toward the releasing position.

Wherein when the driving gear 51 rotates in the first direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to engage with the first driven gear 52 to start driving the pedal lever 1 to move from the retracted position toward the extended position. Wherein before the driving gear 51 rotates in the first direction from the third rotational position to the fourth rotational position, the toothed section 511 of the driving gear 51 simultaneously meshes with the second driven gear 53 and the first driven gear 52 for driving the locking swing arm 32 to move toward the release position while driving the pedal lever 1 to move toward the extended position.

When the driving gear 51 rotates to the fourth rotation position along the first direction, the toothed section 511 of the driving gear 51 starts to disengage from the second driven gear 53, and the locking swing arm 32 rotates to the release position.

During the process that the driving gear 51 rotates from the fourth rotation position to the second rotation position along the first direction, the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52 and the toothless section 512 of the driving gear 51 is opposite to the second driven gear 53, so as to continuously drive the pedal lever 1 to move towards the extending position.

In some embodiments, as shown in fig. 34-36, the vehicle pedal lever device 100 further includes a driving cam 54, a driven cam 55, and a stopper lever 56, the driving cam 54 being connected to the driving gear 51, the driving cam 54 being rotatable with the driving gear 51. The driven cam 55 is connected to the first driven gear 52, and the driven cam 55 can rotate with the first driven gear 52. The stop lever 56 has a first end 561, a second end 562, and a pivot 563, the pivot 563 is located between the first end 561 of the stop lever 56 and the second end 562 of the stop lever 56, and the stop lever 56 is pivotable about the pivot 563.

Wherein when the toothed segment 511 of the driving gear 51 is engaged with the first driven gear 52, the driving cam 54 drives the second end 562 of the stop lever 56 to engage with the second driven gear 53 to stop the rotation of the second driven gear 53, and the driving cam 54 releases the driven cam 55 to allow the rotation of the first driven gear 52.

When the toothed segment 511 of the driving gear 51 is engaged with the second driven gear 53, the driving cam 54 drives the second end 562 of the stop lever 56 to disengage from the second driven gear 53 to allow the second driven gear 53 to rotate, and the driving cam 54 stops the driven cam 55 to stop the first driven gear 52 from rotating.

Further, when the driving gear 51 is engaged with the first driven gear 52, as shown in fig. 35-36, the first end 561 of the stop lever 56 bears against the distal arc of repose 542 of the driving cam 54 such that the second end 562 of the stop lever 56 engages the second driven gear 53 to stop the second driven gear 53 from rotating, and the distal arc of repose 552 of the driven cam 55 is opposite the proximal arc of repose 541 of the driving cam 54.

In other words, when the driving gear 51 is engaged with the first driven gear 52, the driving gear 51 drives the first driven gear 52 to rotate, and the driving cam 54 rotates with the driving gear 51, the near-resting arc 541 of the driving cam 54 is opposite to and spaced apart from the driven cam 55, i.e. the driving cam 54 cannot restrict the movement of the driven cam 55, and the driven cam 55 can rotate with the first driven gear 52. Meanwhile, the distal arc of repose 542 of the driving cam 54 is opposite to the first end 561 of the stop lever 56, and the first end 561 of the stop lever 56 abuts against the distal arc of repose 542 of the driving cam 54, since the stop lever 56 can swing with respect to the pivot 563, the second end 562 of the stop lever 56 is close to the second driven gear 53 and the second end 562 of the stop lever 56 can be engaged on the second driven gear 53 to stop the second driven gear 53 from rotating.

When the toothed segment 511 of the driving gear 51 is engaged with the second driven gear 53, as shown in fig. 34, the distal arc of repose 552 of the driven cam 55 abuts against the distal arc of repose 542 of the driving cam 54, i.e., the distal arc of repose 542 of the driving cam 54 stops against the distal arc of repose 552 of the driven cam 55 to stop the first driven gear 52 from rotating, and the first end 561 of the stop lever 56 abuts against the proximal arc of repose 541 of the driving cam 54 so that the second end 562 of the stop lever 56 is disengaged from the second driven gear 53.

In other words, the active cam 54 has a proximal arc of repose 541 and a distal arc of repose 542. The idler cam 55 has a proximal arc of repose 551 and a distal arc of repose 552. When the driving gear 51 is engaged with the second driven gear 53, as shown in fig. 34, the driving gear 51 drives the second driven gear 53 to rotate, the driving cam 54 rotates with the driving gear 51, and the far-end arc-of-rest segment 542 of the driving cam 54 abuts against the driven cam 55 to stop the driven cam 55 from rotating, thereby stopping the first driven gear 52 from rotating. Meanwhile, the near-resting arc 541 of the driving cam 54 is opposite to the first end 561 of the stop lever 56, and the first end 561 of the stop lever 56 abuts against the near-resting arc 541 of the driving cam 54. Since the stopper swing link 56 can swing with respect to the pivot portion 563, the second end 562 of the stopper swing link 56 is away from the second driven gear 53 to be disengaged from the second driven gear 53.

In some embodiments, the drive gear 51 is integrally formed with the drive cam 54 and the first driven gear 52 is integrally formed with the driven cam 55. It is understood that the driving gear 51 and the driving cam 54 may be two independent members, and the first driven gear 52 and the driven cam 55 may be two independent members.

In some embodiments, the transmission 5 further comprises a driving gear shaft 57, a first driven gear shaft 35 and a second driven gear shaft 36, wherein the driving gear shaft 57 is mounted on the locking seat 31 and connected to the driving motor 6, and the driving gear 51 is mounted on the driving gear shaft 57.

Wherein the first driven gear shaft 35 is a first pivot 35 connecting the locking swing arm 32 and the locking seat 31, a first end of the first driven gear shaft 35 is connected with the arm assembly 23, and the first driven gear 52 is installed at a second end of the first driven gear shaft 35, so that the first driven gear shaft 35 passes through the locking swing arm 32 and the locking seat 31 to be connected with the first arm 231 and/or the second arm 232 of the arm assembly 23, so as to drive the arm assembly 23 to extend and retract under the driving of the first driven gear 52.

The second driven gear shaft 36 is a second pivot shaft 36 connecting the locking seat 31 and the driving rod 33, a first end of the second driven gear shaft 36 is connected to the driving rod 33, and a second driven gear 53 is mounted at a second end of the second driven gear shaft 36, so that the second driven gear 53 is connected to the driving rod 33 through the second pivot shaft 36, so that the second driven gear 53 drives the driving rod 33 to rotate to drive the locking swing arm 32 to swing.

It will be appreciated that the telescopic movement of the drive arm assembly 23 and the manner in which the locking swing arm 32 swings are not limited to being driven by a single drive motor 6, for example in alternative embodiments, as shown in figures 19-20, the arm assembly 23 is driven by a telescopic drive motor 61 and the locking swing arm 32 is driven by a swing drive motor 62, wherein the telescopic drive motor 61 drives the pedal lever 1 through the arm assembly 23 between the retracted position and the extended position and the swing drive motor 62 drives the locking swing arm 32 through the drive rod 33 and the connecting rod 34 to swing between the locking position and the releasing position.

As shown in fig. 13 to 15 and 21 to 26, a vehicle pedal lever device 100 according to an embodiment of the present invention includes a pedal lever 1, a telescopic device 2, a lock seat 31, a swing arm assembly, a transmission 5, and a single drive motor 6, wherein the pedal lever 1 is movable between an extended position and a retracted position.

As shown in fig. 13-15, the telescopic device 2 includes a mounting bracket 21, a pedal bracket 22, and an arm assembly 23. The pedal lever 1 is mounted on a pedal lever support 22, and an arm assembly 23 is pivotally connected to the mounting support 21 and the pedal lever support 22, respectively, to drive the pedal lever 1 between the extended position and the retracted position. In other words, arm assembly 23 is pivotally connected at one end to mounting bracket 21 and at the other end to bar bracket 22, and arm assembly 23 is driven by a drive means, such as a motor, to move bar 1 between the extended and retracted positions. Specifically, the mount bracket 21 may be mounted on the bottom surface 201 of the vehicle body 200.

The swing arm assembly comprises a locking swing arm 32, a connecting rod 34 and a driving rod 33, wherein a first end 341 of the connecting rod 34 is pivotally connected with the locking swing arm 32, a second end 342 of the connecting rod 34 is pivotally connected with a first end 331 of the driving rod 33, a second end 332 of the driving rod 33 is pivotally connected with the locking seat 31, and the driving rod 33 drives the locking swing arm 32 to swing between a locking position and a releasing position through the connecting rod 34. Wherein in the locking position, the locking swing arm 32 and the locking seat 31 lock the pedal lever 1 in the retracted position; in the release position, the lock swing arm 32 and the lock seat 31 release the pedal lever 1 so that the pedal lever 1 can move from the retracted position toward the extended position.

As shown in fig. 24-26, the transmission 5 comprises a driving gear 51, a first driven gear 52 and a second driven gear 53, the first driven gear 52 being drivable by the driving gear 51 and connected to the arm assembly 23 to drive the arm assembly 23 to move the pedal lever 1 between the extended position and the retracted position, the second driven gear 53 being drivable by the driving gear 51 and connected to the driving lever 33 to drive the locking swing arm 32 to swing between the locking position and the releasing position through the driving lever 33.

As shown in fig. 21-23, the drive motor 6 is coupled to a drive gear 51 to drive the arm assembly 23 through the drive gear 51 and a first driven gear 52, and to drive the drive rod 33 through the drive gear 51 and a second driven gear 53. In other words, the drive motor 6, via the transmission 5, can drive both the arm assembly 23 to move the pedal lever 1 between the extended position and the retracted position, and the drive lever 33 to swing the locking swing arm 32 between the locking position and the releasing position.

Wherein the relationship between the rotation of the locking swing arm 32 and the telescopic movement of the arm assembly 23 is:

As shown in fig. 13-15, 21-26, a vehicle pedal lever device 100 according to other embodiments of the present invention includes a pedal lever 1, an arm assembly 23, a lock seat 31, a lock swing arm 32, a connecting rod 34, a drive lever 33, a transmission 5, and a single drive motor 6. Wherein the arm assembly 23 is used to drive the pedal lever 1 between the extended position and the retracted position.

The first end 341 of the connecting rod 34 is pivotally connected to the locking swing arm 32, the first end 331 of the driving rod 33 is pivotally connected to the second end 342 of the connecting rod 34, the second end 332 of the driving rod 33 is pivotally connected to the locking seat 31, and the driving rod 33 drives the locking swing arm 32 to swing through the connecting rod 34.

In some embodiments, as shown in fig. 23, the transmission 5 further includes a driving gear shaft 57, a first driven gear shaft 35 and a second driven gear shaft 36, wherein the driving gear shaft 57 is mounted on the locking base 31 and connected to the driving motor 6, and the driving gear 51 is mounted on the driving gear shaft 57.

In some alternative embodiments, as shown in fig. 24-31, the driving gear 5 includes a toothed section 511 and a non-toothed section 512, and the toothed section 511 of the driving gear 51 alternately meshes with the first driven gear 52 and the second driven gear 53 to alternately drive the first driven gear 52 and the second driven gear 53 to rotate. In other words, the toothed section 511 of the driving gear 51 is not engaged with the first driven gear 52 and the second driven gear 53 at the same time, and is engaged with one driven gear only after being disengaged from the other driven gear.

When the pedal lever 1 is in the retracted position, as shown in fig. 24, the second driven gear 53 is engaged with the toothed section 511 of the driving gear 51, and the first driven gear 52 is opposed to the non-toothed section 512 of the driving gear 51; in the extended position of the pedal lever 1, as shown in fig. 26, the first driven gear 52 is engaged with the toothed section 511 of the driving gear 51, and the second driven gear 53 is opposed to the non-toothed section 512 of the driving gear 51.

In other words, the first driven gear 52 and the second driven gear 53 can be driven by the drive gear 51 having the non-toothed segment 512 and the toothed segment 511. When the pedal lever 1 is in the retracted position, the toothed section 511 of the driving gear 51 engages the second driven gear 53, thereby driving the locking swing arm 32 to swing through the second driven gear 53 to lock the pedal lever 1 in the retracted position, and driving the locking swing arm 32 to swing to release the pedal lever 1, and the toothless section 512 of the driving gear 51 opposes the first driven gear 52, whereby the driving gear 51 does not drive the first driven gear 52 to rotate. When the pedal lever 1 is in the extended position, the toothed section 511 of the driving gear 51 engages the first driven gear 52 to drive the arm assembly 23 to extend and retract through the first driven gear 52 to drive the pedal lever 1 to move, and the non-toothed section 512 of the driving gear 51 opposes the second driven gear 53 so that the driving gear 51 does not drive the second driven gear 53 to rotate.

In some embodiments, drive gear 51 has a first rotational position (e.g., the position of drive gear 51 shown in fig. 24 and the a position shown in fig. 30-31) and a second rotational position (e.g., the position of drive gear shown in fig. 26 and the B position shown in fig. 30-31), and drive gear 51 is reciprocally rotatable between the first rotational position and the second rotational position. Wherein in the first rotational position, as shown in fig. 24, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53, and the toothless section 512 of the driving gear 511 is opposite to the first driven gear 52; in the second rotational position, as shown in fig. 26, the toothed section 511 of the driving gear 511 is engaged with the first driven gear 52 and the non-toothed section 512 of the driving gear 511 is opposed to the second driven gear 53.

Wherein in the particular embodiment shown in fig. 24-26 and 30, the drive gear 51 further includes a third rotational position (e.g., the position shown in fig. 25 and the position C shown in fig. 30) between the first rotational position and the second rotational position, as shown in fig. 24-26 and 30, before the drive gear 51 rotates in the first direction (e.g., counterclockwise as shown in fig. 24-26) from the first rotational position to the third rotational position, as shown in fig. 24-26 and 30, the toothed section 511 of the drive gear 51 meshes with the second driven gear 53, and the toothless section 512 of the drive gear 51 opposes the first driven gear 52, such that the drive gear 51 drives the locking swing arm 32 to rotate from the locking position toward the releasing position.

Wherein the driving gear 51 rotates in the first direction to the third rotational position, as shown in fig. 25, 30, the toothed section 511 of the driving gear 51 starts to disengage from the second driven gear 53 and starts to engage with the first driven gear 52, wherein the locking swing arm 32 rotates to the release position, and the driving gear 51 starts to drive the pedal lever 1 to move from the retracted position toward the extended position.

In the process of rotating the driving gear 51 from the third rotation position to the second rotation position in the first direction, as shown in fig. 26 and 30, the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52 and the toothless section 512 of the driving gear 51 is opposite to the second driven gear 53, so that the driving gear 51 drives the pedal lever 1 to move from the retracted position to the extended position.

Specifically, fig. 30(a) -30(C) show a schematic relationship diagram of the locking swing arm 32 and the second arm 232 during rotation of the driving gear 51 in the first direction from the first rotational position to the second rotational position. Wherein as shown in fig. 30(a), the second arm 232 and the locking swing arm 32 are both in a vertical state, and the second arm 232 is in a retracted position and the locking swing arm 32 is in a locking position, first the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 for driving the locking swing arm 32 to rotate rightward until the locking swing arm 32 rotates rightward by an angle α, i.e., the locking swing arm 32 rotates to a releasing position, as shown in fig. 30(B), wherein the toothed section 511 of the driving gear 51 is disengaged from the second driven gear 53 and starts to be meshed with the first driven gear 52, so that when the locking swing arm 32 is in the releasing position, the driving gear 51 starts to drive the second arm 232 to rotate leftward, so that the second arm 232 starts to move from the retracted position toward the extended position, and the locking swing arm 32 is stationary. Until the second arm 232 is rotated to the left by an angle β, as shown in fig. 30(C), the second arm 232 is moved to the extended position.

Further, before the driving gear 51 rotates in a second direction (clockwise direction as viewed in fig. 27 to 29) opposite to the first direction from the second rotational position to the third rotational position as viewed in fig. 27 to 29, the toothed section 511 of the driving gear 51 meshes with the first driven gear 52 and the non-toothed section 512 of the driving gear 51 opposes the second driven gear 53, so that the driving gear 51 drives the pedal 1 to move from the extended position toward the retracted position.

Wherein the driving gear 51 rotates in the second direction to the third rotational position, as shown in fig. 28, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52 and starts to engage with the second driven gear 53, wherein the pedal lever 1 moves to the retracted position, and the driving gear 51 starts to drive the locking swing arm 32 to move from the releasing position toward the locking position.

In the process of rotating the driving gear 51 from the third rotation position to the first rotation position in the second direction, as shown in fig. 29, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the toothless section 512 of the driving gear 51 is opposite to the first driven gear 52, so that the driving gear 51 drives the locking swing arm 32 to move from the releasing position to the locking position.

Specifically, fig. 30(D) -30(F) show the relationship between the locking swing arm 32 and the second arm 232 during the rotation of the driving gear 51 in the second direction from the second rotational position to the first rotational position. Wherein, as shown in fig. 30(D), the second arm 232 is in the extended position and the locking swing arm 32 is in the locking position, first the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52, for driving the second arm 232 to rotate to the right, to move it from the extended position toward the retracted position, until the second arm 232 rotates to the right by an angle beta, i.e., returns to the original vertical state, as shown in fig. 30(E), the second arm 232 moves to the retracted position, and then the toothed section 511 of the driving gear 51 is disengaged from the first driven gear 52 and starts to engage with the second driven gear 53, for driving the locking swing arm 32 to rotate to the left by the driving gear 51 when the second arm 232 stays at the retracted position, that is, the locking swing arm 32 is driven to rotate from the release position to the locking position until the locking swing arm 32 rotates to the left by an angle α, and as shown in fig. 30(F), the locking swing arm 32 rotates to the locking position.

In the particular embodiment shown in fig. 24-26 and 31, the drive gear 51 also has a third rotational position (position C shown in fig. 31) between the first rotational position (position a shown in fig. 31) and the second rotational position (position B shown in fig. 31) and a fourth rotational position (position D shown in fig. 31) between the second rotational position and the third rotational position,

wherein the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the non-toothed section 511 of the driving gear 51 is opposite to the first driven gear 52 before the driving gear 51 rotates in the first direction (counterclockwise direction as shown in fig. 24 and 26) from the first rotational position to the third rotational position, such that the driving gear 51 drives the locking swing arm 32 to rotate from the locking position toward the releasing position.

Wherein the driving gear 51 rotates in the first direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to disengage from the second driven gear 53, wherein the locking swing arm 32 rotates to the release position. Before the driving gear 51 rotates from the third rotational position to the fourth rotational position in the first direction, the toothless section 512 of the driving gear 51 simultaneously opposes the first driven gear 52 and the second driven gear 53, i.e., the driving gear 51 is not meshed with the first driven gear 52 and the second driven gear 53, so that the locking swing arm 32 is stationary at the release position and the pedal lever 1 is stationary at the retracted position.

Wherein when the driving gear 51 rotates in the first direction to the fourth rotational position, the toothed section 511 of the driving gear 51 starts to engage with the first driven gear 52 to start driving the pedal lever 1 to move from the retracted position toward the extended position. In the process of rotating the driving gear 51 from the fourth rotation position to the second rotation position in the first direction, the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52 and the toothless section 512 of the driving gear 51 is opposite to the second driven gear 53, so that the driving gear 51 drives the pedal lever 1 to move from the retracted position to the extended position.

Specifically, fig. 31(a) -31(D) show a schematic relationship diagram of the locking swing arm 32 and the second arm 232 during the rotation of the driving gear 51 from the first rotational position to the second rotational position in the first direction. Wherein as shown in fig. 31(a), the second arm 232 and the locking swing arm 32 are both in a vertical state, and the second arm 232 is in a retracted position and the locking swing arm 32 is in a locking position, first the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 for driving the locking swing arm 32 to rotate rightward until the locking swing arm 32 rotates rightward by an angle α, that is, the locking swing arm 32 rotates to a releasing position, as shown in fig. 31(B), wherein the toothed section 511 of the driving gear 51 is disengaged from the second driven gear 53. Between the third rotational position and the fourth rotational position, as shown in fig. 31(C), the locking swing arm 32 stays at the release position and the second arm 232 stays at the retracted position, i.e., the toothed section 511 of the driving gear 51 is not meshed with either the second driven gear 53 or the first driven gear 52. Starting from the fourth rotational position, the toothed segment 511 of the driving gear 51 meshes with the first driven gear 52 for driving the second arm 232 to rotate to the left to move the second arm 232 from the retracted position toward the extended position. As shown in fig. 31(D), the second arm 232 is rotated to the left by an angle β, that is, the second arm 232 is moved to the extended position.

Further, as shown in fig. 27, 29 and 31, before the driving gear 51 rotates from the second rotational position to the fourth rotational position in the second direction (clockwise direction shown in fig. 27 and 29) opposite to the first direction, the toothed section 511 of the driving gear 51 meshes with the first driven gear 52, and the non-toothed section 512 of the driving gear 51 opposes the second driven gear 53, so that the driving gear 51 drives the pedal 1 to move from the extended position toward the retracted position.

When the driving gear 51 rotates in the second direction to the fourth rotational position, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52, and the pedal lever 1 moves to the retracted position. Wherein before the driving gear 51 rotates in the second direction from the fourth rotational position to the third rotational position, the toothless section 512 of the driving gear 51 simultaneously opposes the first driven gear 52 and the second driven gear 53, i.e., neither the pedal lever 1 nor the locking swing arm 32 moves.

When the driving gear 51 rotates in the second direction to the third rotation position, the toothed section 511 of the driving gear 51 starts to mesh with the second driven gear 53, i.e., the locking swing arm 32 starts to rotate from the release position toward the locking position. During the process that the driving gear 51 rotates from the third rotation position to the first rotation position along the second direction, the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 and the toothless section 512 of the driving gear 51 is opposite to the first driven gear 52 for driving the locking swing arm 32 to rotate towards the locking position.

Specifically, fig. 31(E) -31(H) show the relationship between the locking swing arm 32 and the second arm 232 during the rotation of the driving gear 51 in the second direction from the second rotational position to the first rotational position. Wherein, as shown in fig. 31(E), the second arm 232 is at the extended position and the locking swing arm 32 is at the locking position, firstly, the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52 for driving the second arm 232 to rotate to the right so as to move from the extended position toward the retracted position until the second arm 232 rotates to the right by an angle β, i.e., returns to the original vertical state, as shown in fig. 31(F), the second arm 232 moves to the retracted position, and then the toothed section 511 of the driving gear 51 is disengaged from the first driven gear 52. Between the fourth rotational position and the third rotational position, as shown in fig. 31(G), the locking swing arm 32 stays at the release position and the second arm 232 stays at the retracted position, i.e., the toothed section 511 of the driving gear 51 is not meshed with either the second driven gear 53 or the first driven gear 52. Starting from the third rotation position, the toothed section 511 of the driving gear 51 starts to mesh with the second driven gear 53 for driving the locking swing arm 32 to rotate leftward, i.e., driving the locking swing arm 32 to rotate from the release position to the locking position until the locking swing arm 32 rotates leftward by an angle α, as shown in fig. 31(H), the locking swing arm 32 rotates to the locking position.

It will be appreciated that in the particular embodiment shown in fig. 30 and 31, the driving gear 51 alternately drives the first driven gear 52 and the second driven gear 53 to rotate, so as to alternate the telescopic movement of the second arm 232 and the swinging movement of the locking swing arm 32.

In other alternative embodiments, as shown in fig. 24-26 and 32, the driving gear 5 includes a toothed section 511 and a non-toothed section 512, the driving gear 51 has a first rotational position (the position of the driving gear 51 shown in fig. 24 and the position a shown in fig. 32), a second rotational position (the position of the driving gear shown in fig. 26 and the position B shown in fig. 32), and a third rotational position (the position C shown in fig. 32) between the first rotational position and the second rotational position, and the driving gear 51 is reciprocally rotatable between the first rotational position and the second rotational position.

Further, the release positions include a maximum release position and a minimum release position, the minimum release position being located between the lock position and the maximum release position, such as the C position shown in fig. 32, where the lock swing arm 32 is at the minimum release position, and the B position shown in fig. 32, where the lock swing arm 32 is at the maximum release position. Before the pedal lever 1 moves away from the retracted position toward the extended position, the lock swing arm 32 rotates from the lock position to the minimum release position from the a position to the C position as shown in fig. 32, and the pedal lever 1 moves from the retracted position to the extended position from the C position to the B position as shown in fig. 32 while the lock swing arm 32 rotates from the minimum release position to the maximum release position.

Specifically, fig. 32(a) -32(C) show a relationship diagram of the locking swing arm 32 and the second arm 232 during the rotation of the driving gear 51 from the first rotational position to the second rotational position in the first direction. Wherein as shown in fig. 32(a), the second arm 232 and the locking swing arm 32 are both in a vertical state, and the second arm 232 is in a retracted position and the locking swing arm 32 is in a locking position, first the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 for driving the locking swing arm 32 to rotate rightward until the locking swing arm 32 rotates rightward by an angle α 1, that is, the locking swing arm 32 rotates to the minimum release position, as shown in fig. 32(B), wherein the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 while starting to be meshed with the first driven gear 52 for simultaneously driving the second arm 232 to rotate leftward, so that the locking swing arm 32 rotates from the minimum release position to the maximum release position, and the second arm 232 moves from the retracted position toward the extended position. As shown in fig. 32(C), the locking swing arm 32 continues to rotate to the right by an angle α 2, i.e., the locking swing arm 32 rotates to the maximum release position, and the second arm 232 rotates to the left by an angle β, i.e., the second arm 232 moves to the extended position.

Further, as shown in fig. 27, 29 and 32, before the driving gear 51 rotates from the second rotational position to the third rotational position in the second direction (clockwise direction as shown in fig. 27, 29) opposite to the first direction, the toothed section 511 of the driving gear 51 simultaneously meshes with the first driven gear 52 and the second driven gear 53 to drive the lock swing arm 32 to rotate from the maximum release position toward the minimum release position while driving the pedal 1 to move from the extended position toward the retracted position.

Wherein when the driving gear 51 rotates in the second direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52, the pedal lever 1 moves to the retracted position and the lock swing arm 32 rotates to the minimum release position.

During the process that the driving gear 51 rotates from the third rotation position to the first rotation position along the second direction, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the toothless section 512 of the driving gear 51 is opposite to the first driven gear 52, so as to drive the locking swing arm 32 to move from the minimum release position to the locking position, and the pedal 1 stays at the retracted position.

Specifically, fig. 32(D) -32(F) show a relationship diagram of the locking swing arm 32 and the second arm 232 in the process of the driving gear 51 in fig. 32 rotating from the second rotational position to the first rotational position in the second direction. Wherein, as shown in fig. 32(D), the second arm 232 is at the extended position and the locking swing arm 32 is at the locking position, first, the toothed segment 511 of the driving gear 51 is engaged with both the first driven gear 52 and the second driven gear 53 for driving the second arm 232 to rotate rightward while driving the locking swing arm 32 to rotate leftward, so that the second arm 232 moves from the extended position toward the retracted position and the locking swing arm 32 moves from the maximum release position toward the minimum release position, until the second arm 232 rotates rightward by an angle β, i.e., the second arm 232 returns to the original vertical state, and the locking swing arm 32 rotates leftward by an angle α 2, as shown in fig. 30(E), the second arm 232 moves to the retracted position, the locking swing arm 32 rotates to the minimum release position, and then the toothed segment 511 of the driving gear 51 is disengaged from the first driven gear 52, i.e., is engaged with only the second driven gear 53, for continuing the rotation of the locking swing arm 32 to the left while the second arm 232 stays at the retracted position, i.e., the locking swing arm 32 is driven to rotate from the minimum release position to the locking position until the locking swing arm 32 rotates to the left by an angle α, as shown in fig. 30(F), and the locking swing arm 32 rotates to the locking position.

In still other alternative embodiments, as shown in fig. 24-26 and 33, the driving gear 5 includes a toothed section 511 and a non-toothed section 512, the driving gear 51 has a first rotational position (the position of the driving gear 51 shown in fig. 24 and the position a shown in fig. 33), a second rotational position (the position of the driving gear shown in fig. 26 and the position B shown in fig. 33), a third rotational position (the position C shown in fig. 33) between the first rotational position and the second rotational position, and a fourth rotational position (the position D shown in fig. 33) between the third rotational position and the second rotational position, and the driving gear 51 is reciprocally rotatable between the first rotational position and the second rotational position.

Further, the release positions include a maximum release position and a minimum release position, the minimum release position being located between the lock position and the maximum release position, such as the C position shown in fig. 33, where the lock swing arm 32 is at the minimum release position, and the D position shown in fig. 33, where the lock swing arm 32 is at the maximum release position. The pedal lever 1 also has an intermediate position between the retracted position and the extended position, as shown in the D position in fig. 33.

Before the pedal lever 1 moves away from the retracted position toward the extended position, the locking swing arm 32 rotates from the locking position to the minimum release position from the a position to the C position as shown in fig. 33, wherein the pedal lever 1 moves from the retracted position to the intermediate position while the locking swing arm rotates from the minimum release position to the maximum release position from the C position to the D position as shown in fig. 33, wherein the locking swing arm 32 is stationary at the maximum release position during the movement of the pedal lever from the intermediate position to the extended position, and from the D position to the B position as shown in fig. 33.

Specifically, fig. 33(a) -33(D) show a relationship diagram of the locking swing arm 32 and the second arm 232 during the rotation of the driving gear 51 from the first rotational position to the second rotational position in the first direction. Wherein as shown in fig. 33(a), the second arm 232 and the locking swing arm 32 are both in a vertical state, and the second arm 232 is in a retracted position and the locking swing arm 32 is in a locking position, first the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 for driving the locking swing arm 32 to rotate rightward until the locking swing arm 32 rotates rightward by an angle α 1, that is, the locking swing arm 32 rotates to the minimum release position, as shown in fig. 33(B), wherein the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 while starting to be meshed with the first driven gear 52 for simultaneously driving the second arm 232 to rotate leftward, so that the locking swing arm 32 rotates from the minimum release position to the maximum release position, and the second arm 232 moves from the retracted position toward the intermediate position. As shown in fig. 33(C), the locking swing arm 32 continues to rotate rightward by an angle α 2, that is, the locking swing arm 32 rotates to the maximum release position, and the second arm 232 rotates leftward by an angle β 1, that is, the second arm 232 moves to the intermediate position, in which the toothed section 511 of the driving gear 51 is disengaged from the second driven gear 53, and then the second arm 232 continues to rotate leftward by an angle β 2, so that the second arm 232 moves from the intermediate position to the extended position, as shown in fig. 33 (D).

Further, as shown in fig. 27, 29 and 33, before the driving gear 51 rotates from the second rotational position to the fourth rotational position in the second direction (clockwise direction as shown in fig. 27 and 29) opposite to the first direction, the toothed section 511 of the driving gear 51 is opposed to the first driven gear 52 and the non-toothed section 512 of the driving gear 51 is opposed to the second driven gear 53 for driving the pedal lever 1 to move from the extended position toward the retracted position.

Wherein when the driving gear 51 rotates in the second direction to the fourth rotation position, the toothed section 511 of the driving gear 51 starts to engage with the second driven gear 53 to start driving the locking swing arm 32 to rotate from the maximum releasing position toward the locking position, and the pedal lever 1 moves to the intermediate position.

Before the fourth rotation position of the driving gear 51 is rotated to the third rotation position along the second direction, the toothed section of the driving gear is engaged with the first driven gear and the second driven gear simultaneously, so as to drive the locking swing arm 32 to rotate and drive the pedal lever 1 to move simultaneously. Wherein when the driving gear 51 rotates in the second direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52, the pedal lever 1 moves to the retracted position, and the lock swing arm 32 rotates to the minimum release position.

During the process that the driving gear 51 rotates from the third rotation position to the first rotation position along the second direction, the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53 and the non-toothed section of the driving gear 51 is opposite to the first driven gear 52, so as to drive the locking swing arm 32 to move from the minimum release position to the locking position.

Specifically, fig. 33(E) -33(H) show the relationship between the locking swing arm 32 and the second arm 232 in the process of the driving gear 51 in fig. 33 rotating in the second direction from the second rotational position to the first rotational position. Wherein, as shown in fig. 33(E), the second arm 232 is in the extended position and the locking swing arm 32 is in the locking position, first, the toothed segment 511 of the driving gear 51 and the first driven gear 52 for driving the second arm 232 to rotate to the right, so that the second arm 232 moves from the extended position toward the retracted position, until the second arm 232 rotates to the right by an angle β 2, that is, the second arm 232 moves to the middle position, as shown in fig. 33(F), and then the toothed segment 511 of the driving gear 51 starts to engage with the second driven gear 53, that is, the second arm 232 is driven to continue to move while the locking swing arm 32 is driven to rotate to the left, so that the second arm 232 moves from the middle position toward the retracted position, and the locking swing arm 32 moves from the maximum release position toward the minimum release position, until the second arm 232 rotates to the right by an angle β 1 to return to the vertical state, and the locking swing arm 32 rotates to the left by an angle α 2, as shown in fig. 33(G), the second arm 232 moves to the retracted position, and the locking swing arm 32 rotates to the minimum release position, in which the toothed segment 511 of the driving gear 51 is disengaged from the first driven gear 52, i.e., is engaged with only the second driven gear 53, so that the locking swing arm 32 continues to rotate to the left while the second arm 232 stays in the vertical state, to drive the locking swing arm 32 to rotate from the minimum release position toward the locking position until the locking swing arm 32 continues to rotate to the left by an angle α 1, as shown in fig. 33(H), and the locking swing arm 32 rotates to the locking position.

It will be appreciated that in the embodiment shown in figures 32 and 33, the toothed section 511 of the driving gear 51 has an overlap with the meshing of the first and second driven gears 52, 53, i.e. there is a time during which the toothed section 511 of the driving gear 51 meshes with both the first and second driven gears 52, 53.

In some embodiments, as shown in fig. 34-36, the vehicle pedal lever device 100 further includes a driving cam 54, a driven cam 55, and a stop lever 56, the driving cam 54 being coupled to the driving gear 51, the driving cam 54 being rotatable with the driving gear 51. The driven cam 55 is connected to the first driven gear 52, and the driven cam 55 can rotate with the first driven gear 52. The stop lever 56 has a first end 561, a second end 562, and a pivot 563, the pivot 563 is located between the first end 561 of the stop lever 56 and the second end 562 of the stop lever 56, and the stop lever 56 is pivotable about the pivot 563.

A transmission according to an embodiment of the present invention will be described with reference to fig. 24 to 29, fig. 30 to 31, and fig. 34 to 36.

As shown in fig. 24 to 29, the transmission 5 according to the embodiment of the present invention includes a driving gear 51, a first driven gear 52 and a second driven gear 53, the driving gear 51 has a non-toothed section 512 and a toothed section 511, and the toothed section 511 of the driving gear 51 alternately meshes with the first driven gear 52 and the second driven gear 53 to alternately drive the first driven gear 52 and the second driven gear 53 to rotate.

In other words, the toothed section 511 of the driving gear 51 is not engaged with the first driven gear 52 and the second driven gear 53 at the same time, and the toothed section 511 of the driving gear 51 is engaged with one driven gear only after the toothed section 511 of the driving gear 51 is disengaged from the other driven gear.

In some embodiments, drive gear 51 has a first rotational position (shown as the position of drive gear 51 in fig. 24 and the a position shown in fig. 30-31) and a second rotational position (shown as the position of drive gear in fig. 26 and the B position shown in fig. 30-31), drive gear 51 being reciprocally rotatable between the first rotational position and the second rotational position. Wherein in the first rotational position, as shown in fig. 24, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53, and the toothless section 512 of the driving gear 511 is opposite to the first driven gear 52; in the second rotational position, as shown in fig. 26, the toothed section 511 of the driving gear 511 is engaged with the first driven gear 52 and the non-toothed section 512 of the driving gear 511 is opposed to the second driven gear 53.

In some alternative embodiments, the driving gear 51 further has a third rotational position (the position shown in fig. 25 and the C position shown in fig. 30) between the first rotational position and the second rotational position, as shown in fig. 24-26 and 30, before the driving gear 51 rotates in the first direction (the counterclockwise direction as shown in fig. 24-26) from the first rotational position to the third rotational position, as shown in fig. 24 and 30, the toothed section 511 of the driving gear 51 meshes with the second driven gear 53, and the toothless section 512 of the driving gear 51 opposes the first driven gear 52, to drive the second driven gear 53 through the driving gear 51 without driving the first driven gear 52.

When the driving gear 51 rotates in the first direction to the third rotational position, as shown in fig. 25 and 30, the toothed segment 511 of the driving gear 51 starts to disengage from the second driven gear 53 and starts to engage with the first driven gear 52.

In the process of rotating the driving gear 51 from the third rotation position to the second rotation position in the first direction, as shown in fig. 26 and 30, the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52 and the toothless section 512 of the driving gear 51 is opposite to the second driven gear 53, so that the driving gear 51 drives the first driven gear 52 and does not drive the second driven gear 53.

Further, as shown in fig. 27-29, before the driving gear 51 rotates in a second direction (clockwise as shown in fig. 27-29) opposite to the first direction from the second rotational position to the third rotational position, as shown in fig. 27, the toothed section 511 of the driving gear 51 meshes with the first driven gear 52, and the non-toothed section 512 of the driving gear 51 opposes the second driven gear 53.

Wherein the driving gear 51 rotates in the second direction to the third rotational position, as shown in fig. 28, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52 and starts to engage with the second driven gear 53.

In the process of rotating the driving gear 51 from the third rotation position to the first rotation position in the second direction, as shown in fig. 29, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the toothless section 512 of the driving gear 51 is opposite to the first driven gear 52.

In still other alternative embodiments, as shown in fig. 24, 26 and 31, the drive gear 51 further has a third rotational position (position C shown in fig. 31) between the first rotational position (position a shown in fig. 31) and the second rotational position (position B shown in fig. 31) and a fourth rotational position (position D shown in fig. 31) between the second rotational position and the third rotational position,

wherein the toothed section 511 of the driving gear 51 meshes with the second driven gear 53 and the non-toothed section 511 of the driving gear 51 opposes the first driven gear 52 before the driving gear 51 rotates in the first direction (counterclockwise as viewed in fig. 24 and 26) from the first rotational position to the third rotational position.

When the driving gear 51 rotates to the third rotational position along the first direction, the toothed section 511 of the driving gear 51 starts to disengage from the second driven gear 53. Before the driving gear 51 rotates from the third rotational position to the fourth rotational position in the first direction, the toothless section 512 of the driving gear 51 is simultaneously opposite to the first driven gear 52 and the second driven gear 53, i.e. the driving gear 51 is not meshed with the first driven gear 52 and the second driven gear 53.

Wherein when the driving gear 51 rotates in the first direction to the fourth rotational position, the toothed section 511 of the driving gear 51 starts to engage with the first driven gear 52 to start driving the pedal lever 1 to move from the retracted position toward the extended position. During the process of rotating the driving gear 51 from the fourth rotation position to the second rotation position along the first direction, the toothed section 511 of the driving gear 51 is meshed with the first driven gear 52 and the toothless section 512 of the driving gear 51 is opposite to the second driven gear 53.

Further, as shown in fig. 27, 29 and 31, before the driving gear 51 rotates from the second rotational position to the fourth rotational position in the second direction (clockwise direction in fig. 27 and 29) opposite to the first direction, the toothed section 511 of the driving gear 51 meshes with the first driven gear 52, and the toothless section 512 of the driving gear 51 opposes the second driven gear 53.

When the driving gear 51 rotates in the second direction to the fourth rotational position, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52. Before the driving gear 51 rotates in the second direction from the fourth rotational position to the third rotational position, the toothless section 512 of the driving gear 51 is simultaneously opposite to the first driven gear 52 and the second driven gear 53.

When the driving gear 51 rotates in the second direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to mesh with the second driven gear 53. During the process that the driving gear 51 rotates from the third rotation position to the first rotation position along the second direction, the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53, and the non-toothed section 512 of the driving gear 51 is opposite to the first driven gear 52.

In some embodiments, as shown in fig. 34-36, the transmission 5 further includes a first stop member 501, the first stop member 501 stopping the rotation of the first driven gear 52 when the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and releasing the first driven gear 52 when the toothed section 511 of the driving gear 51 is disengaged from the second driven gear 53.

In some specific embodiments, the transmission 5 further includes a second stopper member 56, the second stopper member 56 stopping the second driven gear 53 from rotating when the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52, and releasing the second driven gear 53 when the toothed section 511 of the driving gear 51 is disengaged from the first driven gear 52.

In other words, the first stopper member 501 and the second stopper member 56 can prevent the second driven gear 53 from rotating when the driving gear 51 drives the first driven gear 52 to rotate, and the second stopper member 56 can prevent the second driven gear 53 from rotating due to inertia and the like, because the rotation of the first driven gear 52 and the second driven gear 53 is not performed simultaneously. When the driving gear 51 drives the second driven gear 53 to rotate, the first stop member 501 can stop the first driven gear 52 from rotating, so as to avoid the first driven gear 52 from rotating due to inertia and the like.

In the position shown in fig. 34, the first stopper member 501 stops the first driven gear 52 from rotating. In the position shown in fig. 36 and the position shown in fig. 35, the second stopper member 56 stops the second driven gear 53 from rotating.

In some embodiments, the transmission 5 further comprises a driving cam 54, a driven cam 55 and a stop rocker 56. The drive cam 54 is connected to the drive gear 51, and the drive cam 54 is rotatable together with the drive gear 51. The driven cam 55 is connected to the first driven gear 52, and the driven cam 55 can rotate with the first driven gear 52.

The stop lever 56 has a first end 561, a second end 562, and a pivot 563, the pivot 563 is located between the first end 561 of the stop lever 56 and the second end 562 of the stop lever 56, and the stop lever 56 is pivotable about the pivot 563.

Further, when the toothed segment 511 of the driving gear 51 is engaged with the first driven gear 52, the driving cam 54 drives the second end 562 of the stop lever 56 to engage with the second driven gear 53 to stop the second driven gear 53 from rotating, and the driving cam 54 releases the driven cam 55 to allow the first driven gear 52 to rotate,

Specifically, when the driving gear 51 is engaged with the first driven gear 52, as shown in fig. 35-36, the first end 561 of the stop lever 56 bears against the distal arc of repose 542 of the driving cam 54 such that the second end 562 of the stop lever 56 engages the second driven gear 53 to stop the second driven gear 53 from rotating, and the distal arc of repose 552 of the driven cam 55 is opposite the proximal arc of repose 541 of the driving cam 54.

It is understood that the stop lever 56, as the second stop member 56, is capable of stopping the rotation of the second driven gear 53 when the toothed segment 511 of the driving gear 51 is engaged with the first driven gear 52, and releasing the second driven gear 53 when the toothed segment 511 of the driving gear 51 is disengaged from the first driven gear 52, so that the driving gear 51 can drive the second driven gear 53 to rotate when the toothed segment 511 of the driving gear 51 is engaged with the second driven gear 53.

It is understood that the driving cam 54 and the driven cam 55 as the first stopper 501 can stop the rotation of the first driven gear 52 when the toothed segment 511 of the driving gear 51 is engaged with the second driven gear 53, and release the first driven gear 52 when the toothed segment 511 of the driving gear 51 is disengaged from the second driven gear 53, so that the driving gear 51 can rotate the first driven gear 52 when the toothed segment 511 of the driving gear 51 is engaged with the first driven gear 52.

When the driving gear 51 rotates from the first rotational position to the second rotational position, as shown in fig. 34, the toothed segment 511 of the driving gear 51 first drives the second driven gear 53 to rotate, the distal arc 542 of the driving cam 54 abuts against the distal arc 542 of the driven cam 54 to stop the first driven gear 52 from rotating, and the first end 561 of the stop lever 56 abuts against the proximal arc 541 of the driving cam 54 to disengage the second end 562 of the stop lever 56 from the second driven gear 53. Then, as shown in fig. 35, the driving gear 51 rotates such that the toothed section 511 of the driving gear 51 is disengaged from the second driven gear 53 and is engaged with the first driven gear 52, and the driving cam 54 rotates with the driving gear 51 such that the near-stop arc section 541 of the driving cam 54 and the driven cam 54 are opposite to and spaced apart from each other, the near-stop arc section 541 of the driving cam 54 does not constrain the driven cam 54, and the first end of the stop lever 56 abuts against the far-stop arc section 542 of the driving cam 54 such that the second end 562 of the stop lever 56 is engaged on the second driven gear 53 to stop the rotation of the second driven gear 53.

In some embodiments, the driving gear 51 is disposed coaxially with the driving cam 54, and the first driven gear 52 is disposed coaxially with the driven cam 55.

A transmission according to further embodiments of the present invention will now be described with reference to fig. 24-29, 32 and 34-36.

As shown in fig. 24 to 29, the transmission 5 according to the embodiment of the present invention includes a driving gear 51, a first driven gear 52, and a second driven gear 53, the driving gear 51 having a non-toothed section 512 and a toothed section 511, the driving gear 51 having a first rotational position (the position of the driving gear 51 shown in fig. 24 and the a position shown in fig. 32), a second rotational position (the position of the driving gear shown in fig. 26 and the B position shown in fig. 32), and a third rotational position (the C position shown in fig. 32) between the first rotational position (the a position shown in fig. 32) and the second rotational position (the B position shown in fig. 32), the driving gear 51 being reciprocally rotatable between the first rotational position and the second rotational position.

Wherein the toothed section 511 of the drive gear 51 meshes with the second driven gear 53 and the non-toothed section 512 of the drive gear 51 opposes the first driven gear 52 before the drive gear 51 rotates in the first direction (counterclockwise direction in fig. 24 and 26) from the first rotational position to the third rotational position.

When the driving gear 51 rotates in the first direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to mesh with the first driven gear 52. In the process that the driving gear 51 rotates from the third rotation position to the second rotation position along the first direction, the toothed section 511 of the driving gear 51 is simultaneously meshed with the second driven gear 53 and the first driven gear 52.

In some specific embodiments, as shown in fig. 27, 29 and 32, before the driving gear 51 rotates from the second rotational position to the third rotational position in a second direction (clockwise as shown in fig. 27 and 29) opposite to the first direction, the toothed segment 511 of the driving gear 51 meshes with both the first driven gear 52 and the second driven gear 53.

When the driving gear 51 rotates in the second direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52. During the process that the driving gear 51 rotates from the third rotation position to the first rotation position along the second direction, the toothed section 511 of the driving gear 51 is meshed with the second driven gear 53, and the non-toothed section 512 of the driving gear 51 is opposite to the first driven gear 52.

It will be appreciated that in the embodiment shown in fig. 33, the toothed section 511 of the driving gear 51 has an overlapping portion with the meshing of the first and second driven gears 52, 53, i.e. there is a certain time and during this time, the toothed section 511 of the driving gear 51 meshes with both the first and second driven gears 52, 53.

In other words, the first stopper member 501 and the second stopper member 56 can prevent the second driven gear 53 from rotating when the driving gear 51 drives the first driven gear 52 to rotate, and the second stopper member 56 can prevent the second driven gear 53 from rotating due to inertia and the like, because the rotation of the first driven gear 52 and the second driven gear 53 is not performed simultaneously. When the driving gear 51 drives the second driven gear 53 to rotate to drive the locking swing arm 32 to swing, the first stop member 501 can stop the first driven gear 52 from rotating, so as to avoid the first driven gear 52 from rotating due to inertia and the like.

A transmission according to further embodiments of the present invention will now be described with reference to figures 24-29, 33 and 34-36.

As shown in fig. 24-29, the transmission 5 according to the embodiment of the present invention includes a driving gear 51, a first driven gear 52 and a second driven gear 53, the driving gear 51 having a non-toothed section 512 and a toothed section 511, the driving gear 51 having a first rotational position (the position of the driving gear 51 shown in fig. 24 and the a position shown in fig. 33), a second rotational position (a position of the drive gear shown in fig. 26 and a position B shown in fig. 33), a third rotational position (a position C shown in fig. 33) between the first rotational position (a position a shown in fig. 33) and the second rotational position (a position B shown in fig. 33), and a fourth rotational position (a position D shown in fig. 33) between the second rotational position and the third rotational position, the moving gear 51 being reciprocally rotatable between the first rotational position and the second rotational position.

In the first rotational position, as shown in fig. 24, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53, and the toothless section 512 of the driving gear 511 is opposed to the first driven gear 52; in the second rotational position, as shown in fig. 26, the toothed section 511 of the driving gear 511 is engaged with the first driven gear 52 and the non-toothed section 512 of the driving gear 511 is opposed to the second driven gear 53.

Before the driving gear 51 rotates in the first direction (counterclockwise direction in fig. 24 and 26) from the first rotational position to the third rotational position, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the toothless section 512 of the driving gear 51 is opposed to the first driven gear 52.

When the driving gear 51 rotates to the third rotational position in the first direction, the toothed section 511 of the driving gear 51 starts to mesh with the first driven gear 52. Before the driving gear 51 rotates from the third rotational position to the fourth rotational position in the first direction, the toothed section 511 of the driving gear 51 meshes with the second driven gear 53 and the first driven gear 52 simultaneously.

When the driving gear 51 rotates to the fourth rotational position in the first direction, the toothed section 511 of the driving gear 51 starts to disengage from the second driven gear 53.

During the process that the driving gear 51 rotates from the fourth rotation position to the second rotation position along the first direction, the toothed section 511 of the driving gear 51 is meshed with the first driven gear 52 and the toothless section 512 of the driving gear 51 is opposite to the second driven gear 53.

In some embodiments, as shown in fig. 27, 29 and 33, the toothed section 511 of the drive gear 51 is opposite the first driven gear 52 and the non-toothed section 512 of the drive gear 51 is opposite the second driven gear 53 before the drive gear 51 is rotated in a second direction (clockwise as shown in fig. 27 and 29) opposite the first direction from the second rotational position to a fourth rotational position.

When the driving gear 51 rotates to the fourth rotation position in the second direction, the toothed section 511 of the driving gear 51 starts to mesh with the second driven gear 53.

Before the driving gear 51 rotates in the fourth direction to the third rotational position, the toothed section of the driving gear is engaged with the first driven gear and the second driven gear simultaneously to drive the locking swing arm 32 to rotate and drive the pedal lever 1 to move simultaneously. When the driving gear 51 rotates in the second direction to the third rotational position, the toothed section 511 of the driving gear 51 starts to disengage from the first driven gear 52.

In the process that the driving gear 51 rotates from the third rotation position to the first rotation position in the second direction, the toothed section 511 of the driving gear 51 is engaged with the second driven gear 53 and the non-toothed section of the driving gear 51 is opposite to the first driven gear 52.

In some embodiments, the transmission 5 further includes a second stopper 56, the second stopper 56 stopping the second driven gear 53 from rotating when the toothed section 511 of the driving gear 51 is engaged with the first driven gear 52, and releasing the second driven gear 53 when the toothed section 511 of the driving gear 51 is disengaged from the first driven gear 52.

In other words, the first stop member 501 and the second stop member 56 can stop the rotation of the second driven gear 53 when the driving gear 51 drives the first driven gear 52 to rotate, and the second stop member 56 can stop the rotation of the second driven gear 53 to avoid the rotation of the second driven gear 53 caused by inertia and the like, when the first driven gear 52 and the second driven gear 53 do not operate simultaneously. When the driving gear 51 drives the second driven gear 53 to rotate, the first stop member 501 can stop the first driven gear 52 from rotating, so as to avoid the first driven gear 52 from rotating due to inertia and the like.
