Detailed Description

The technical scheme of the invention is further explained by the specific implementation mode in combination with the attached drawings.

As shown in fig. 1 to 3 and 19, a front wheel frame 10 of a foldable scooter of the present invention, a handle bar stem 20 connected to the front wheel frame 10, and a foot pedal 30 for mounting a rear wheel.

Wherein, the front wheel support 10 is the roughly rectangle form that can twist into roughly parallelogram, installs two front wheels 11 respectively at the both ends of front wheel support 10, so, scooter when turning, front wheel support 10 adaptability twists reverse according to the angle of turning, and it is lighter to turn.

The handle stem 20 of the present invention is adjustable according to the height of the user. Specifically, the handlebar stem 20 of the present invention includes a first sleeve 22 and a second sleeve 23 sleeved with each other, a plurality of adjusting holes 24 are formed on the second sleeve 23 along an axial direction thereof, a pin hole for a pin to enter and exit is formed on the first sleeve 22, the first sleeve 22 slides to a corresponding hole position of the adjusting hole 24 along the second sleeve 23, and the pin is clamped on the corresponding adjusting hole 24, thereby completing the length adjustment of the handlebar stem 20. In addition, the handlebar stem 20 is mounted on the front wheel frame 10 through the connection member 70, as shown in fig. 10, the connection member 70 is provided with a first through hole 73 and a second through hole 74 which are perpendicular to each other, one end of the second sleeve 23 is mounted in the first through hole 73, and the other end of the second sleeve 23 is mounted with the handlebar 21; the connecting member 70 is mounted to the front wheel frame 10 through the second through-hole 74 such that the lateral axis of the front wheel frame 10 passes through the second through-hole 74 and the lateral axis of the front wheel frame 10 is restricted from rotating relative to the second through-hole 74.

In order to avoid the condition that the two sides of the pedal 30 are unbalanced in stress and fall down when the bicycle turns, a pedal swinging mechanism is connected between the pedal 30 and the handlebar stem 20. As shown in fig. 4 to 9, the pedal swing mechanism includes a pedal attachment base 40 and a link plate 50 rotatably connected, the pedal attachment base 40 being installed in an end portion of the pedal 30, and the link plate 50 being connected to the connector 70.

Specifically, an opening 41 is formed in the end portion of the pedal connecting base 40, the opening 41 is a square hole, a square flexible member 42 in tight fit with the opening 41 is connected in the opening 41 in a sleeved mode, the flexible member 42 is made of rubber, and a clamping groove 43 with a cross-shaped section is formed in the flexible member 42; the end of the connecting plate 50 is provided with a chuck 51 which is matched with the clamping groove 43 and has a cross-shaped section. The clamping head 51 is clamped in the clamping groove 43, when one side of the pedal plate 30 is stressed (or the two sides of the pedal plate 30 are stressed in an unbalanced manner), the clamping head 51 can extrude the flexible part 42 to deform, so that the pedal plate connecting seat 40 can drive the pedal plate 30 to slightly rotate or slightly swing relative to the connecting plate 50, and the force is relieved or prevented from acting on the pedal plate 30. That is, the flexible member 42 is pressed by the chuck 51 to generate a damping effect, so that the pedal is balanced, and the user is prevented from falling down from the scooter when turning.

To prevent the flexible member 42 from exiting the opening 41 during use, the present invention engages a square cover 44 within the opening 41 to restrain the flexible member 42 within the opening 41.

As a preferred embodiment of the present invention, the present invention provides a limiting structure on the foot pedal connecting seat 40 and the connecting plate 50, which are matched to limit the micro-rotation or micro-swing amplitude of the foot pedal 30. Specifically, the method comprises the following steps. The limiting structure comprises two arc-shaped grooves 52 arranged at the end part of the connecting plate 50 and respectively positioned at two sides of the clamping head 51 and two limiting columns 45 arranged at the end part of the pedal connecting seat 40 and respectively positioned at two sides of the opening 41, and the two limiting columns 45 can respectively slide along the two arc-shaped grooves 52. The arc of the arc-shaped slot 52 is suitable for the pedal 30 to rotate or swing 5-15 degrees. Of course, the two arc-shaped slots 52 can be arranged on the end of the pedal connecting seat 40, and the two limit posts 45 can be correspondingly arranged on the end of the connecting plate 50.

Because the pedal connecting seat 40 drives the pedal 30 to slightly rotate or slightly swing relative to the connecting plate 50, in order to prevent the end of the pedal 30 from contacting with the end of the connecting plate 50 and scratching the end of the pedal 30 and the end of the connecting plate 50, a gasket 62 is arranged between the end of the pedal 30 and the end of the connecting plate 50 to prevent the end of the pedal 30 from contacting with the end of the connecting plate 50 in a surface-to-surface manner.

As a preferred embodiment of the present invention, the pedal swing mechanism of the present invention further includes a spindle 60 passing through the connection between the pedal connecting seat 40 and the connecting plate 50 to make the pedal connecting seat 40 and the connecting plate 50 located on the same axis, and two bearings 61 connected to the pedal connecting seat 40 and provided on the spindle 60 for the rotation of the pedal connecting seat 40 relative to the spindle 60. That is, the spindle 60 penetrates through the footboard connecting seat 40, penetrates through the center of the flexible member 42, that is, the cover plate 44, and penetrates into the center hole of the chuck 51, and the spindle 60 ensures that the connecting seat 40 does not deviate relative to the connecting plate 50 when the footboard 30 rotates slightly or swings, thereby improving the stability during turning.

The connecting plate 50 of the swing mechanism of the foot board is connected to the connecting member 70 connecting the handle bar stem 20 and the front wheel frame 10, so that the handle bar stem 20 of the present invention can be folded on the foot board 30 or pulled out from the foot board 20 in order to further reduce the folded volume of the scooter of the present invention. Specifically, the link plate 50 is rotatably coupled to the link member 70. As shown in fig. 2, 8 and 10, the connecting plate 50 has two side walls 53, the two side walls 53 are provided with corresponding arc-shaped limiting grooves 54 which take the center of the connecting part 70 and the side wall 53 as the center of a circle, and both ends of the arc-shaped limiting grooves 54 are bent and extended; the connecting piece 70 is provided with a limiting shaft 71 which can slide along the arc-shaped limiting groove 54 in a penetrating way, and the limiting shaft 71 is rotatably connected with a handle 72 which can clamp or release the limiting shaft 71 to slide along the arc-shaped limiting groove 54.

The present invention bends and extends both ends of the arc-shaped position-limiting groove 54, so as to prevent the position-limiting shaft 71 from continuously sliding along the arc-shaped section of the arc-shaped position-limiting groove 54 under the action of external force after the handlebar stem 20 is folded or the handlebar stem 20 is unfolded, so as to limit the handlebar stem 20 in the folded state or the unfolded state. Similarly, in order to make the limiting shaft 71 enter the arc-shaped section of the arc-shaped limiting groove 54 from the two ends of the arc-shaped limiting groove 54 to slide, the invention sets two opposite long holes 75 on the connecting piece 70, and the positions of the two long holes 75 can correspond to the bending extension ends of the arc-shaped limiting groove 54, and simultaneously make the two ends of the limiting shaft 71 respectively limited on the two long holes 75. When the handlebar stem 20 is folded, the handle 72 is pressed tightly, so that the limit shaft 71 slides to the arc-shaped section of the arc-shaped limit groove 54 along one of the bent extending ends of the long hole 75 and the arc-shaped limit groove 54, and when the limit shaft 71 slides to the other bent extending end along the arc-shaped section of the arc-shaped limit groove 54, the handle 72 is pulled, so that the limit shaft 71 slides along the other bent extending end of the long hole 75 and the arc-shaped limit groove 54 to stagger the arc-shaped section of the arc-shaped limit groove 54.

In order to further reduce the size of the scooter of the present invention after folding, the rear wheel mounted on the footrest 30 of the present invention can be folded, and specifically, a wheel folding mechanism is provided on the footrest 30, and the wheel folding mechanism can be retracted into the inner space of the footrest 30 or pulled out from the inner space of the footrest 30.

As shown in fig. 11 to 15, the wheel folding mechanism includes a wheel mounting bracket 80 and a support bracket 90 rotatably connected to each other, the wheel mounting bracket 80 is used for mounting a wheel 81 (rear wheel), and the support bracket 90 is rotatably connected to the footrest 30 and the wheel mounting bracket 80. Specifically, the support frame 90 is provided with an arc groove 91 on the end face rotatably connected with the wheel mounting frame 80, the wheel mounting frame 80 is provided with a sliding column 82 capable of sliding along the arc groove 91 on the end face rotatably connected with the support frame 90, and when the wheel mounting frame 80 rotates relative to the support frame 90, the wheel 81 is driven to rotate to an open state (a state perpendicular to the ground) or a folded state (a state of being flatly placed in the pedal plate 30).

The wheel 81 is rotated from a flat state to a state vertical to the ground, that is, the wheel 81 is rotated by 90 degrees, and the radian of the arc groove 91 can be used for the wheel 81 to rotate by 90 degrees.

Further, in order to limit the wheel 81 to the opened state or the folded state, the present invention provides a limiting component on the wheel mounting bracket 80 or the supporting bracket 90 to limit the wheel 81 to the opened state or the folded state. The limiting assembly comprises two top beads 92 which are rotatably arranged on the end face of the support frame 90 and the wheel mounting frame 80 and two springs 93 which are arranged in the support frame 90 and respectively abut against the two top beads 92, and the top beads 92 tightly push the wheel mounting frame 80 under the action of the springs 93, so that the wheels 81 are kept in an opening state or a folding state. Of course, two top balls can also be arranged on the end surface of the wheel mounting frame rotatably connected with the support frame, and the two springs are correspondingly arranged in the wheel mounting frame 80.

As a preferred embodiment of the present invention, a rolling groove 83 for the top ball 92 to roll when the wheel mounting bracket 80 rotates is formed on the end surface of the wheel mounting bracket 80, three positioning slots 84 for positioning two top balls 92 are concavely formed on the rolling groove 83, and an included angle between two adjacent positioning slots 84 is 90 °, so that when the wheel 81 rotates by 90 °, an arc length of the top ball 92 rolls also corresponds to 90 °. Of course, when the top ball is arranged on the end face of the wheel mounting frame, the corresponding rolling groove is arranged on the end face of the support frame, and the positioning clamping groove is correspondingly arranged on the rolling groove on the support frame.

The wheel mount 80 of the present invention has two opposing side wings 85, and the wheel 81 is pivotally connected to the two side wings 85 by an axle 811. When the scooter is used in rainy weather, a mudguard 87 rotatably connected to the wheel mounting bracket 80 and covering the wheel 81 is provided between the side wings 85 to prevent the pedal 30 from being contaminated by mud. The fender 87 is rotatably connected to the wheel mounting frame 80, and when a mud strikes the fender 87, the fender 87 can slightly rotate due to the rotational connection, thereby buffering the striking force of the mud to extend the service life of the fender 87. Specifically, the mudguard 87 is rotatably connected with the wheel mounting rack 80 through the pivot 88, the pivot 88 is sleeved with a first torsion spring 89, one end of the first torsion spring 89 is connected with the mudguard 87, the other end of the first torsion spring 89 abuts against the inner side of the wheel mounting rack 80, and the micro-rotation of the mudguard 87 is realized by utilizing the torsional force of the first torsion spring 89.

In order to facilitate the folding and unfolding operations of the wheels 81, the present invention rotatably connects the support frame 90 to the pedal 30 through the rotating shaft 102. When the wheels 81 are folded, the wheels 81 are pulled out from the pedals 30, at this time, the support frame 90 rotates along the rotating shaft 102, so that the support frame 90 and the wheel mounting frame 80 are separated from the pedals 30, then the wheels are rotated by 90 degrees, and the wheel mounting frame 80 rotates by 90 degrees relative to the support frame 90, so that the wheels are unfolded. On the contrary, when the wheel is folded, the wheel is rotated in the opposite direction by 90 degrees, so that the wheel mounting frame 80 is rotated in the opposite direction by 90 degrees relative to the support frame 90, and then the support frame 90 is rotated in the opposite direction along the rotating shaft 102, so that the wheel 81 is pushed into the pedal 30, and the folding process is completed.

In order to tightly support the support frame 90 in the pedal plate 30, the rotating shaft 102 of the present invention is further sleeved with a second torsion spring 103, one end of which is connected with the support frame 90, and the other end of which is pressed against the inner side of the pedal plate 30. By using the torque of the second torsion spring 103, when the wheel 81 is folded into the pedal 30 and the wheel is completely opened, the support frame 90 is tightly pressed against the pedal 30, so as to ensure that the scooter runs more stably.

As a preferred embodiment of the present invention, the wheel folding mechanism of the present invention further includes a support shaft 100 penetrating from the inside of the wheel mounting bracket 80 to the inside of the support bracket 90, so that the wheel mounting bracket 80 and the support bracket 90 are located on the same axis, and two bearings 101 connected to the wheel mounting bracket 80 and provided for the wheel mounting bracket 80 to rotate relative to the support shaft 100 are disposed on the support shaft 100. The support shaft 100 ensures that the wheel mounting bracket 80 does not deviate from the support bracket 90 when the wheel 81 is folded or unfolded, improving reliability.

The present invention is to lock the wheel folding mechanism to the inner space of the footrest 30 by the locking mechanism 200 provided on the footrest 30. Specifically, as shown in fig. 3 and 15 to 18, the locking mechanism includes a button cover 201 connected to the foot pedal 30, a pin 202 slidably inserted into the button cover 201, and a button 203 inserted into the button cover 201, wherein the button 203 is configured to drive the pin 202 to slide into the locking hole 86 of the wheel mounting bracket 80 relative to the button cover 201. When the end of the pin 202 is located in the locking hole 86 of the wheel mount 80, the wheel mount 80 is restricted from rotating relative to the support bracket 90, thereby locking the wheel folding mechanism in the inner space of the footrest 30; when the pin 202 is disengaged from the wheel mounting bracket 80, the wheel 81 can be pulled to open the wheel.

In order to enable the button 203 to drive the pin 202 to slide relative to the button cover 201, the pin 202 is provided with an inclined groove 204 along the length direction thereof, and the end part of the pin 202, which is used for extending into the locking hole 86, is provided with an inclined surface 205; the button 203 is provided with a sloped block 206 that can be inserted into the sloped groove 204 and is attached to the sloped wall of the sloped groove 204. When the button 203 is pressed, the inclined block 206 moves towards the direction of extending into the inclined groove 204, and the inclined block 206 is attached to the inclined wall of the inclined groove 204, so that the pin 202 moves perpendicular to the inclined block 206 and enters the locking hole 86 on the wheel mounting bracket 80; because the end of the pin 202 extending into the locking hole 86 is the inclined surface 205, when the wheel 81 is pulled out from the pedal 30, the inclined surface 205 of the pin 202 is forced by the pulling force to slide out along the locking hole 86, so that the pin 202 is separated from the wheel mounting frame 80, and the wheel 81 can be opened.

As shown in fig. 1, 2 and 19, when the scooter is folded, the rear wheel is retracted into the pedal and then the handle bar vertical tube is turned, so that the scooter can be folded into the structure shown in fig. 19, the volume after folding is small, and the boxing volume is greatly reduced.
