Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

A folding mechanism 100 for a treadmill 1 and a treadmill 1 according to an embodiment of the present application are described below with reference to fig. 1 to 7.

As shown in fig. 1, a folding mechanism 100 according to an embodiment of the present application includes a riser 10 and a dial holder 20.

Specifically, the first end of the stand pipe 10 is provided with a connecting portion 11, and the connecting portion 11 is provided with a hinge hole 111 and a limiting hole 112. The watch frame 20 includes a body 20a, the body 20a is provided with a hinge portion 21 and a limiting portion 22 spaced from each other, the hinge portion 21 is pivotally connected to the hinge hole 111, and the limiting portion 22 includes a movable limiting member 221. The dial holder 20 rotates between a first position and a second position relative to the vertical pipe 10, and the limiting member 221 forms a limiting fit with the limiting hole 112 when the dial holder 20 is located at the second position.

In the present embodiment, folding mechanism 100 may be used with treadmill 1. When the folding mechanism 100 is in a use state, the dial plate holder 20 is located at a first position relative to the stand pipe 10; in the stored state of the folding mechanism 100, the dial holder 20 is located at the second position with respect to the stem 10.

In one example, the folding mechanism 100 may be mounted to the base 200 of the treadmill 1. The stand pipe 10 can be fixedly disposed on the base 200, and can also rotate relative to the base 200. When the treadmill 1 is in use, the stand pipe 10 can be disposed at an acute angle or vertically with respect to the base 200, and the dial plate frame 20 can rotate within a certain angle range with respect to the stand pipe 10. Wherein the dial support 20 is used for mounting a display device and/or a control panel of the treadmill 1.

Illustratively, the first end of the riser 10 may be an upper end of the riser 10, the connecting portion 11 is sleeved on the upper end of the riser 10, and the connecting portion 11 is provided with a hinge hole 111 and a limiting hole 112 that are spaced apart from each other. The hinge portion 21 of the body 20a is provided with a pivot hole corresponding to the hinge hole 111, and the shaft 12 is disposed through the hinge hole 111 and the pivot hole, so that the hinge portion 21 can rotate relative to the connecting portion 11, and the body 20a can rotate relative to the stand pipe 10.

Wherein, the turning radius formed between the hinge portion 21 and the position-limiting portion 22 is consistent with the distance between the hinge hole 111 and the position-limiting hole 112, so that when the dial frame 20 is turned to the second position, the position between the position-limiting portion 22 and the position-limiting hole 112 corresponds to form a position-limiting fit.

In one example, the limiting member 221 can move back and forth along a preset direction, and at least part of the limiting member 221 is located in the limiting hole 112 to form a plug-pin fit, so that a lock is formed between the dial plate frame 20 and the stand pipe 10; alternatively, the stopper 221 is disengaged from the stopper hole 112, thereby releasing the lock between the watch plate holder 20 and the riser 10. The position-limiting member 221 may be configured to be a column, and the predetermined direction may be an axial direction of the position-limiting member 221.

It will be understood that the first and second positions refer to the position of watch plate holder 20 relative to riser 10. For example, as shown in fig. 2, the first position may be a position in which the dial holder 20 is rotated to an angle of 60 degrees with respect to the stand pipe 10; as shown in fig. 3, the second position may be a position where the dial holder 20 is rotated to an angle of 0 degrees with respect to the vertical pipe 10, that is, the dial holder 20 is parallel to the vertical pipe 10 when in the second position.

It should be noted that, in other examples of the present application, the first position and the second position may be adjusted according to actual needs, and this is not specifically limited in this embodiment of the present application.

According to treadmill 1 of the embodiment of the present application, by providing hinge hole 111 on connecting portion 11 of riser 10 and providing hinge portion 21 on body 20a of dial frame 20, dial frame 20 is rotated between the first position and the second position relative to riser 10 by pivotal cooperation of hinge portion 21 and hinge hole 111. Thereby, the dial holder 20 can be rotated to the first position when the folding mechanism 100 is used, and the dial holder 20 can be rotated to the second position after use, thereby facilitating the housing of the folding mechanism 100. Furthermore, by providing the limiting hole 112 on the connecting portion 11 of the vertical tube 10 and providing the movable limiting member 221 on the dial rack 20, when the dial rack 20 rotates to the second position, the position of the dial rack 20 relative to the vertical tube 10 is locked by the limiting cooperation of the limiting member 221 and the limiting hole 112, so that the stability of the folding mechanism 100 during use is improved. Moreover, when the folding mechanism 100 needs to be stored, the movement of the limiting piece 221 is controlled to disengage the limiting piece 221 from the limiting hole 112, so that the locking between the dial rack 20 and the stand pipe 10 is released, and the dial rack 20 is further rotated from the first position to the second position, thereby improving the convenience of the folding mechanism 100 during storage.

As shown in fig. 1, in an embodiment, the position-limiting part 22 further includes a first elastic member 222, and the first elastic member 222 is configured to apply an elastic force to the position-limiting member 221, so that the position-limiting member 221 is always in the locking position.

The locking position refers to a position where the limiting member 221 can form a limiting fit with the limiting hole 112.

Illustratively, the first elastic member 222 may be a spring, for example, a compression spring or an extension spring may be used. It is understood that the compression spring refers to a spring that is always in a compressed state, and applies its elastic force in a tensile direction to the stopper 221; the extension spring refers to a spring that is always in a stretched state, and applies its elastic force in a compression direction to the stopper 221.

In this embodiment, the specific arrangement of the first elastic element 222 and the limiting element 221 is not limited herein, as long as the elastic force applied to the limiting element 221 by the first elastic element 222 in the deformed state is satisfied, so that the limiting element 221 is always in the locking position.

When the limiting member 221 is in the locking position, the limiting member 221 and the limiting hole 112 form a latch fitting, so that the dial plate holder 20 and the stem 10 form a locking state. When the locking state between the watch case holder 20 and the riser 10 needs to be released, the state of the first elastic member 222 can be changed by applying an external force to the limiting member 221, so that the limiting member 221 can be disengaged from the limiting hole 112, even if the first elastic member 222 moves from the locking position to the unlocking position.

According to the above embodiment, the elastic force of the first elastic member 222 can make the position-limiting member 221 always be in the locking position, so that the position of the position-limiting member 221 does not need to be manually adjusted, and the position-limiting member 221 and the position-limiting hole 112 automatically form the position-limiting fit when the dial frame 20 rotates to the second position.

As shown in fig. 1, in an embodiment, the position-limiting portion 22 further includes a first support plate 223 and a second support plate 224 that are disposed at an interval, the first support plate 223 and the second support plate 224 are connected to the main body 20a and respectively have through holes, and the position-limiting member 221 is movably disposed in the two through holes. The limiting member 221 is provided with a first anti-falling portion 221a and a second anti-falling portion 221b, the first anti-falling portion 221a forms anti-falling fit with the through hole of the first support plate 223, the second anti-falling portion 221b forms anti-falling fit with the through hole of the second support plate 224, the first elastic member 222 is sleeved on the limiting member 221, two ends of the first elastic member 222 are respectively abutted between the first support plate 223 and the second anti-falling portion 221b, the first elastic member 222 is usually in a compressed state and applies elastic force to the second anti-falling portion 221b, so that the limiting member 221 is usually in a locked position.

Illustratively, the first and second brackets 223 and 224 are provided at intervals in the length direction of the body 20a, and the first and second brackets 223 and 224 are provided extending obliquely downward from the lower side surface of the body 20 a. The through holes of the first support plate 223 correspond to the through holes of the second support plate 224, so that the limiting members 221 can be slidably inserted into the two through holes. The first retaining portion 221a is located on a side of the first leg 223 away from the second leg 224, and the second retaining portion 221b is located between the first leg 223 and the second leg 224. The first elastic member 222 may be a compression spring, and both ends of the first elastic member 222 respectively abut between the first support 223 and the second retaining portion 221b, and the compression spring respectively applies elastic force to the first support 223 and the second retaining portion 221b in a direction away from each other, so that the second retaining portion 221b always abuts against the second support 224.

It can be understood that the first retaining portion 221a is in retaining fit with the through hole of the first support plate 223, and the second retaining portion 221b is in retaining fit with the through hole of the second support plate 224, which means that the shape or size of the first retaining portion 221a is larger than that of the through hole of the first support plate 223, and the shape or size of the second retaining portion 221b is larger than that of the through hole of the second support plate 224, so that the first retaining portion 221a cannot pass through the through hole of the first support plate 223 and the second retaining portion 221b cannot pass through the through hole of the second support plate 224, thereby preventing the limiting member 221 from disengaging from the through holes of the first support plate 223 and the second support plate 224.

In a specific example, the limiting member 221 is provided with two mounting holes spaced apart from each other, and the first and second retaining portions 221a and 221b are in interference fit with the two mounting holes, respectively, so as to fix the first and second retaining portions 221a and 221b to the limiting member 221, respectively.

According to the above embodiment, the stopper 221 and the first elastic member 222 are fitted to each other, and the first and second retaining portions 221a and 221b are provided in the stopper 221, so that the stopper 221 is prevented from coming off the through holes of the first and second support plates 223 and 224, and the structural reliability of the stopper 22 is improved.

As shown in fig. 1, in one embodiment, the connection portion 11 has a hollow structure, the limit hole 112 is provided to penetrate through a wall of the connection portion 11, the connection portion 11 is further provided with a first unlocking portion 113, the first unlocking portion 113 is movably provided to the connection portion 11, and the position of the connection portion 11 corresponds to the position of the limit hole 112. The first unlocking portion 113 is adapted to drive the limiting member 221 to move under an external force, so that the limiting member 221 and the limiting hole 112 are unlocked.

Illustratively, the connecting portion 11 is a hollow structure to define a cavity therein. When the dial holder 20 is at the second position, the position-limiting portion 22 of the dial holder 20 is located in the cavity, and the free end of the position-limiting member 221 extends out of the cavity through the position-limiting hole 112, so that the position-limiting member 221 and the position-limiting hole 112 form a position-limiting fit. The first unlocking portion 113 is disposed outside the cavity and corresponds to the position of the limiting hole 112, so that the first unlocking portion 113 can contact with the free end of the limiting member 221. The first unlocking portion 113 drives the limiting member 221 to move under the action of an external force, so that the limiting member 221 is separated from the limiting hole 112, and the limiting fit between the limiting member 221 and the limiting hole 112 is released.

According to the above embodiment, the user can drive the limiting member 221 to move through the first unlocking portion 113 by pressing the first unlocking portion 113 to apply an external force to the first unlocking portion 113, so as to release the limiting engagement between the limiting member 221 and the limiting hole 112, and further rotate the dial rack 20 from the second position to the first position, thereby further improving the convenience of the folding mechanism 100 in storage.

As shown in fig. 2, in one embodiment, the dial holder 20 and the stem 10 are parallel and flush with each other with the dial holder 20 in the second position.

Illustratively, the dial holder 20 is adapted to be configured as a flat plate structure. In the case where the dial holder 20 is located at the second position, the longitudinal direction of the dial holder 20 and the longitudinal direction of the stem 10 are parallel to each other, and the lower side surface of the dial holder 20 and the outer side surface of the stem 10 are in contact with each other.

Through the above embodiment, under the condition that the dial plate frame 20 rotates to the second position, the fitting degree between the dial plate frame 20 and the stand pipe 10 is improved, the overall size of the dial plate frame 20 and the stand pipe 10 is reduced, the occupation of the space is reduced, and the storage effect of the folding mechanism 100 is improved.

As shown in fig. 2 and 3, in one embodiment, a side surface of the body 20a facing the vertical pipe 10 is further provided with a buffer member 23, and the buffer member 23 is in contact with the vertical pipe 10 when the dial plate 20 is in the second position.

For example, the material of the buffer member 23 may be a soft material, such as rubber.

Through the above embodiment, when the dial plate frame 20 is rotated to the second position, the buffer member 23 is in contact with the vertical pipe 10, so that a certain buffering effect can be achieved, the dial plate is prevented from directly colliding with the vertical pipe 10, and a certain protection effect is achieved.

As shown in fig. 1 and 2, in one embodiment, the lower surface of the body 20a is supported on the upper end surface of the connecting portion 11 with the dial holder 20 in the second position.

Illustratively, the lower surface of the body 20a and the upper end surface of the connection part 11 are each configured as a plane, and the upper end surface of the connection part 11 is disposed in parallel with a horizontal plane. Thus, when the dial holder 20 is in the second position, the lower surface of the body 20a is in surface contact with the upper end surface of the connecting portion 11, and the body 20a is parallel to the horizontal plane.

Through the above embodiment, under the condition that the dial rack 20 is located at the second position, the contact area between the body 20a and the connecting portion 11 is increased, so that the supporting effect of the stand pipe 10 on the dial rack 20 is improved, and the stability of the dial rack 20 at the second position is improved.

As shown in fig. 4, in one embodiment, the vertical pipes 10 are two pipes arranged side by side and spaced apart from each other, the dial frame 20 further includes two arm portions 20b corresponding to the two vertical pipes 10, the two arm portions 20b are formed by extending the main body 20a in the same direction, and the two arm portions 20b are provided with a hinge portion 21 and a stopper portion 22, respectively.

Illustratively, two armrest portions 20b are provided at intervals in the width direction of the body 20a, the two armrest portions 20b being formed by the rear side edges of the body 20a extending rearward, respectively. The two armrest portions 20b and the rear side edge of the body 20a together define a moving space. The first ends of the two vertical pipes 10 are respectively provided with a connecting portion 11, and are rotatably connected with the respective armrest portions 20b through the connecting portions 11. The second ends of the two risers 10 are each fixedly or rotatably connected to the base 200 of the treadmill 1.

Through the above embodiment, on the one hand, the stability of the overall structure of the folding mechanism 100 is improved, so that the support through the two stand pipes 10 is more stable when the watch plate frame 20 is at the first position, and on the other hand, the armrest parts 20b respectively connected with the two stand pipes 10 are arranged, so that the support can be provided for the hands of the user when the user uses the treadmill 1, thereby improving the user experience.

As another aspect of the embodiment of the present application, the embodiment of the present application also provides a treadmill 1.

As shown in fig. 2 to 7, the treadmill 1 of the embodiment of the present application includes a base 200 and a folding mechanism 100 according to the above-described embodiment of the present application. Wherein the second end of the stand pipe 10 is rotatably connected to the base 200 such that the stand pipe 10 rotates between an open position and a folded position relative to the base 200.

Illustratively, with the stand pipe 10 in the open position, the length direction of the stand pipe 10 has a preset included angle with the plane of the base 200, wherein the preset included angle may be 60 degrees. With the riser 10 in the folded position, the angle between the length direction of the riser 10 and the plane in which the foundation 200 is located may be 0 degrees, i.e. the riser 10 is arranged parallel to the foundation 200.

It is understood that the angle between the stand pipe 10 in the open position and the folded position relative to the base 200 can be specifically set according to practical situations, and the embodiment of the present invention is not particularly limited thereto.

Further, as shown in fig. 2, treadmill 1, when in use, may rotate riser 10 to an open position and dial shelf 20 to a first position; as shown in fig. 7, treadmill 1 may rotate dial shelf 20 to the second position and rotate riser 10 to the folded position when stowed.

According to treadmill 1 of the embodiment of the present application, by using folding mechanism 100 according to the above-mentioned embodiment of the present application and rotatably providing stand pipe 10 of folding mechanism 100 to base 200, structural stability of treadmill 1 in use and convenience in storage are improved, and treadmill 1 can reduce overall dimension as much as possible in storage, thereby reducing occupation of storage space.

As shown in fig. 4 and 5, in one embodiment, the second end of the stand pipe 10 is provided with a rotating shaft 12 rotatably engaged with the base 200, and a locking member 13 is connected to an end of the rotating shaft 12, and the locking member 13 rotates synchronously with the rotating shaft 12. The base 200 is further provided with a movable locking matching portion 30, the locking matching portion 30 is provided with a locking matching groove 30a, and the locking piece 13 and the locking matching groove 30a form limiting matching under the condition that the stand pipe 10 is located at the opening position or the folding position.

Illustratively, the base 200 is provided with a pivot through hole, and the rotating shaft 12 of the second end of the stand pipe 10 is pivotally inserted into the pivot through hole. The locking member 13 is fixedly connected to the free end of the rotating shaft 12 and rotates synchronously with the rotating shaft 12. The locking engagement portion 30 is adapted to move between a locking position and an unlocking position, and the locking engagement portion 30 is usually located at the locking position, so that at least a portion of the locking member 13 is embedded in the locking engagement groove 30a of the locking engagement portion 30, and a limit engagement is formed.

It will be appreciated that in the event that the latch member 13 forms a positive engagement with the latch engagement slot 30a, the stand pipe 10 cannot rotate relative to the base 200, thereby maintaining the stand pipe 10 in the open or folded position. When the stand pipe 10 needs to be rotated from the open position to the folded position, or from the folded position to the open position, the locking fitting part 30 is controlled to move so that the locking piece 13 is disengaged from the locking fitting groove 30a, and the limit fitting between the locking piece 13 and the locking fitting groove 30a is released, so that the stand pipe 10 can be rotated relative to the base 200.

Through the above embodiment, the structural stability of the stand pipe 10 can be improved when the treadmill 1 is in use, that is, when the stand pipe 10 is in the open position, and the stand pipe 10 can be unlocked by controlling the movement of the locking engagement portion 30 when the treadmill 1 needs to be stored, so that the stand pipe 10 can be rotated to the folded position, thereby improving the convenience of storing the treadmill 1.

As shown in fig. 4 and 5, in one embodiment, the locking engagement portion 30 includes a link mechanism 31, a first end of the link mechanism 31 is provided with a locking engagement groove 30a, a second end of the link mechanism 31 is provided with a second unlocking portion 32, and the second unlocking portion 32 drives the locking engagement groove 30a to be engaged with or disengaged from the locking member 13 under an external force.

Illustratively, the link mechanism 31 includes a first link 311, a second link 312, and a third link 313 connected in series. The first end of the first link 311 is the first end of the link mechanism 31, and the first end of the first link 311 is provided with a locking engagement groove 30 a. The second end of the first link 311 is rotatably engaged with the first end of the second link 312, and the first link 311 has a rotating shaft between the first end and the second end thereof, and the rotating shaft is rotatably disposed on the base 200, so that the first link 311 can rotate relative to the base 200. The first end of the third link 313 is rotatably engaged with the second end of the second link 312, the second end of the third link 313 is the second end of the link mechanism 31, and the second end of the third link 313 is provided with a second unlocking portion 32. The third link 313 is provided with a rotation shaft between the first end and the second end thereof, and the rotation shaft is rotatably provided to the base 200, whereby the third link 313 can be rotated with respect to the base 200.

It can be understood that, by applying an external force to the second unlocking portion 32 at the second end of the third link 313, the third link 313 can drive the first link 311 to rotate via the second link 312, so that the position of the locking engagement groove 30a at the first end of the first link 311 changes, and the locking engagement groove 30a forms a limit engagement or a disengagement with the locking member 13.

According to the above embodiment, the user can move the position of the locking engagement groove 30a by the link mechanism 31 by stepping on the second unlocking portion 32 to apply an external force to the second unlocking portion 32, and further release the limit engagement between the locking member 13 and the engagement groove, thereby further improving the convenience of the treadmill 1 when being stored.

In one embodiment, as shown in fig. 5, the lock engagement portion 30 further includes a second elastic member 33, and the second elastic member 33 is used for applying an elastic force to the second end of the link mechanism 31, so that the lock engagement groove 30a is always in a lock position in limit engagement with the lock member 13.

Illustratively, the second elastic member 33 may be an extension spring, and one end of the extension spring is connected to the second end of the third link 313, and the other end of the extension spring is connected to the base 200, so that the extension spring always applies an elastic force to the third link 313 and the locking engagement groove 30a of the first end of the first link 311 is always in the locking position by the link mechanism 31.

According to the above embodiment, the locking engagement groove 30a can be always in the locking position by the elastic force of the second elastic member 33, so that there is no need to manually adjust the position of the locking engagement groove 30a, and the locking member 13 automatically forms the limit engagement with the locking engagement groove 30a when the stand pipe 10 is in the folded position or the unfolded position.

As shown in FIG. 6, in one embodiment, treadmill 1 further comprises a cushioning air strut 40, a first end of cushioning air strut 40 rotatably coupled to base 200, and a second end of cushioning air strut 40 rotatably coupled to locking member 13.

Illustratively, the first end of the buffer pneumatic rod 40 is a fixed end of the buffer pneumatic rod 40, and the fixed end of the buffer pneumatic rod 40 is rotatably fixed to the base 200. The second end of the buffer air pressure rod 40 is a telescopic end of the buffer air pressure rod 40, and the telescopic end of the buffer air pressure rod 40 is rotatably fixed on the locking piece 13.

It will be appreciated that during the rotation of the stand pipe 10 from the open position to the folded position, the telescopic end of the buffer air pressure rod 40 moves in the contracting direction and the stand pipe 10 rotates slowly by the air pressure buffering action inside the buffer air pressure rod 40.

Through the above embodiment, in the process that the stand pipe 10 rotates from the open position to the folded position, a certain buffering effect can be provided for the stand pipe 10, and the stand pipe 10 is prevented from directly rotating towards the base 200 to cause collision, so that the stand pipe 10 and the base 200 are protected to a certain extent.

As shown in fig. 7, in one embodiment, with the riser 10 in the folded position relative to the base 200 and the dial holder 20 in the second position relative to the riser 10, the dial holder 20 and the riser 10 and the base 200 are both parallel and attached to each other.

Illustratively, the stand pipes 10 are two and are respectively disposed on both sides of the base 200 in the width direction. In the case where the stand pipe 10 is in the folded position, two stand pipes 10 are disposed in parallel with the base 200 and are respectively located on both sides in the width direction of the base 200. Meanwhile, the dial holder 20 is in the second position, and the dial holder 20 is disposed in parallel with the base 200.

Further, the dial holder 20 is provided with a display device that can be rotated to a position parallel to the base 200 with the dial holder 20 in the second position.

With the above-described embodiment, when the treadmill 1 needs to be stored, by rotating the stand pipe 10 to the folded position and rotating the dial frame 20 to the second position, the size of the treadmill 1 in the height direction is minimized, thereby further improving the storage effect of the treadmill 1.
