Detailed Description

Reference will now be made in detail to embodiments of the present utility model, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the drawings are illustrative and intended to explain the present utility model and should not be construed as limiting the utility model.

As shown in fig. 1 to 9, a frame assembly 100 of an embodiment of the present utility model includes a frame 1, a pedal 2, a driving assembly 3, and a link mechanism 4.

As shown in fig. 1, the frame 1 may be generally rectangular plate-like and extend generally in the front-rear direction. As shown in fig. 4, the pedal 2 may also be substantially rectangular plate-like, the pedal 2 may be mounted on the left or right side of the frame 1, and the pedal 2 may be movable in the width direction (left-right direction) of the frame 1 with respect to the frame 1, and after the movement adjustment, the position of the pedal 2 may have a first position and a second position.

When the pedal 2 is moved to the first position, as shown in fig. 4 to 7, at this time, the pedal 2 is extended to the outside (left or right) of the frame 1, as shown in fig. 7, and the user's (rider's) foot can tread on the pedal 2, whereby the extension of the pedal 2 has the effect of enhancing the overall surface width of the frame assembly 100.

When the step 2 is moved to the second position, as shown in fig. 1 to 3, at this time, the step 2 is retracted toward the inside of the frame 1, and it should be noted that only a part of the step 2 may be retracted into the frame 1, that is, in the up-down direction, a partial projection of the step 2 and a partial projection of the frame 1 overlap. In other embodiments, the step 2 may also be retracted entirely into the frame 1, i.e. in the up-down direction, the entire projection of the step 2 being located within the projection of the frame 1. By retracting the step 2 into the frame 1, the overall width dimension of the frame assembly 100 is reduced, which serves to reduce the overall structural dimension.

It should be noted that, the frame 1 may be provided with a structure such as an assembly groove and a cavity, and the pedal 2 may be inserted into the assembly groove or the cavity when retracted, and in other embodiments, the retraction of the pedal 2 may also be that the pedal 2 is hidden at the bottom side of the frame 1 or overlapped at the top side of the frame 1.

A drive assembly 3 is provided to the frame 1 and is used to drive the pedal 2 between the first and second positions. For example, as shown in fig. 1, the driving component 3 may be disposed at a front end of the frame 1 and connected to the pedal 2, the driving component 3 may include a driving device such as an air cylinder, an electric push rod, etc., and the driving pedal 2 may be slidably assembled on a lateral direction of the frame 1 through a guide slot or a guide rail, and the pedal 2 may be adjusted in a left-right position by extending and retracting the driving component 3, so as to switch between the first position and the second position of the pedal 2.

At least part of the linkage 4 is connected between the pedal 2 and the drive assembly 3 and is adapted to oscillate upon actuation of the drive assembly 3 to switch the pedal 2 to the first or second position. For example, the linkage mechanism 4 may be a four-bar mechanism, a crank linkage mechanism 4, etc., the input end of the linkage mechanism 4 may be in transmission connection with the driving component 3, the output end of the linkage mechanism 4 may be connected with the pedal 2, and the linkage mechanism 4 may convert the rotation motion or the expansion motion of the driving component 3 into an acting force for driving the pedal 2 to move, so that the position adjustment of the pedal 2 is convenient.

Secondly, the arrangement of the connecting rod mechanism 4 can also play a role in separating the driving assembly 3 from the pedal 2, so that the condition that the acting force born by the pedal 2 is directly transmitted to the driving assembly 3 is avoided, and the protection effect on the driving assembly 3 is achieved. In addition, the self-locking function can be realized by means of the self structure of the link mechanism 4 or the cooperation with the frame 1 and the like, so that the pedal 2 can be conveniently kept at the position after switching, and the stability of the structure during use can be enhanced.

According to the frame assembly 100 provided by the embodiment of the utility model, when the pedal 2 is switched to the first position, the pedal 2 can be used for improving the surface width of the pedal 2 of the scooter, so that the condition that the surface width is small and the support to a human body is insufficient is avoided, and further, the turning operation is convenient. When the pedal 2 is switched to the second position, the pedal 2 can retract into the frame 1, so that the overall size of the frame assembly 100 can be reduced, the occupation of space is reduced, and the storage is convenient.

In addition, by adopting the transmission mode of the driving component 3 and the connecting rod mechanism 4, the stability and the reliability of the structure can be improved, and the driving safety can be further ensured.

In some embodiments, in the first position, the pedal 2 is stopped against the frame 1 so that the pedal 2 can withstand the pedaling force of the user. For example, the pedal 2 may be fitted under the frame 1, and when the pedal 2 is switched to the second position, a part or all of the pedal 2 may be hidden under the frame 1.

As shown in fig. 6 and 7, when the pedal 2 is switched to the first position, the pedal 2 may extend to the right side of the frame 1, at this time, the left side edge of the pedal 2 is located below the frame 1 and may stop against the frame 1, and when the pedal 2 receives a downward force F1, the squeezing action between the left side edge of the pedal 2 and the frame 1 is enhanced, so that the pedal 2 can bear the pedaling force of the user by virtue of the interaction of the pedal 2 and the frame 1, and the support requirement is satisfied.

In some embodiments, the linkage 4 includes a first link 41, one end of the first link 41 is rotatably connected to the pedal 2, and the other end of the first link 41 is rotatably connected to the frame 1, and in the first position, the pedal 2, the frame 1, and the first link 41 form a triangle structure so that the pedal 2 can bear the pedaling force of the user.

For example, as shown in fig. 7, the top end of the first link 41 may be hinged to the frame 1, the bottom end of the first link 41 may be hinged to the pedal 2, and the junction of the first link 41 and the pedal 2 may be located at a substantially middle position of the pedal 2 in the left-right direction. Thus, when the pedal 2 is switched to the first position, the hinge between the first link 41 and the pedal 2 may form a fulcrum, and at this time, when the pedal 2 receives a pedaling force (force F1 and is located on the right side of the fulcrum), the left portion of the pedal 2 may swing upward around the fulcrum, that is, the pedal 2 may rest on the bottom of the frame 1 and may generally apply a force (force F2) obliquely upward to the frame 1, and the frame 1 may apply a reaction force to the left portion of the pedal 2, by which the swing of the pedal 2 may be restricted, so that the pedal 2 may satisfy the effect of supporting the user.

It should be noted that, as shown in fig. 7, in the first position, the triangle structure formed by the pedal 2, the frame 1 and the first link 41 is the triangle shape surrounded by the dashed line in fig. 7, in this position, the distance between the hinge of the pedal 2 and the first link 41 and the pedal 2 in the up-down direction will remain unchanged due to the abutment of the pedal 2 and the frame 1, and the supporting effect of the pedal 2 is fully satisfied by virtue of the structural stability of the triangle shape.

In some embodiments, the linkage 4 includes a second link 42, one end of the second link 42 is rotatably connected to the pedal 2, the other end of the second link 42 is rotatably connected to the frame 1, and the driving assembly 3 is connected to the second link 42 and is configured to drive the second link 42 to swing to switch the pedal 2 between the first position and the second position.

For example, as shown in fig. 6 and 7, the top end of the second link 42 may be hinged with the frame 1, the bottom end of the second link 42 may be hinged with the pedal 2, the second link 42 may be located inside the first link 41, and for example, the second link 42 may be located on the left side of the first link 41 when the pedal 2 is mounted on the right side of the frame 1. Thus, the frame 1, the first link 41, the second link 42 and the pedal 2 as a whole can form a four-bar linkage,

the driving assembly 3 may include a motor, a driving shaft of the motor may be connected with the second connecting rod 42, and swing driving of the second connecting rod 42 may be achieved through rotation of the driving shaft of the motor, so that swing driving of the link mechanism 4 (the first connecting rod 41 and the second connecting rod 42) may be achieved, and thus reciprocating switching of the pedal 2 between the first position and the second position may be achieved (only through forward and reverse rotation adjustment of the motor).

In some embodiments, in the first position, the pivotal connection of the pedal 2 and the second link 42 is stopped with the frame 1. For example, as shown in fig. 7, the four-bar linkage formed by the frame 1, the first link 41, the second link 42, and the pedal 2 has a dead point, that is, a position where the pedal 2 is switched to the link mechanism 4 at the first position. In this position, the hinged connection of the second link 42 and the pedal 2 can be entirely stopped against the frame 1, thus simultaneously serving to limit the continued swinging of the second link 42 and to limit the rotation of the pedal 2 about the fulcrum.

In some embodiments, the rotational connection position of the first link 41 and the pedal 2 forms a first connection 411, and the rotational connection position of the second link 42 and the pedal 2 forms a second connection 421, and in the first position, the connection direction of the first connection 411 and the second connection 421 coincides with the extension direction of the second link 42.

For example, as shown in fig. 6, the first connection 411 may be a hinge between the first link 41 and the pedal 2, and the second connection 421 may be a hinge between the second link 42 and the pedal 2, and in the first position, a line connecting the hinge between the first link 41 and the pedal 2 and the hinge between the second link 42 and the pedal 2 is substantially the same as an extending direction of the second link 42. Thus, the condition that the second connecting rod 42 easily applies a blocking acting force to the pedal 2 when the pedal 2 is switched to the second position can be avoided, and the pedal 2 can be conveniently switched between different positions.

In some embodiments, the pedal 2 is provided with a shaft portion 23, and the second link 42 is rotatably connected to the shaft portion 23, and in the first position, the shaft portion 23 is stopped against the frame 1. For example, as shown in fig. 7 to 9, the shaft portion 23 may be integrally fixed to the pedal 2, and the shaft portion 23 may extend substantially in the front-rear direction, and the second link 42 may be rotatably connected to the shaft portion 23, for example, a corresponding end portion of the second link 42 may be sleeved on an outer peripheral side of the shaft portion 23 and may be rotatable circumferentially with respect to the shaft portion 23.

As shown in fig. 9, the shaft portion 23 may extend to the outside of the second link 42, and when the pedal 2 is switched to the first position, the shaft portion 23 that is leaked may stop with the frame 1, so as to play a role in restricting the swing of the pedal 2.

In some embodiments, there are two linkages 4, the two linkages 4 are oppositely disposed, and one side of the pedal 2 is connected to the frame 1 by one of the linkages 4, and the other side of the pedal 2 is connected to the frame 1 by the other linkage 4.

For example, as shown in fig. 8, the pedal 2 may be correspondingly provided with two link mechanisms 4, one of which 4 may be located on the front side of the pedal 2 and the other 4 may be located on the rear side of the pedal 2, whereby the stability of the movement of the pedal 2 may be enhanced. Secondly, both sides all can be equipped with shaft portion 23 around pedal 2, and the shaft portion 23 of both sides can realize the spacing restraint of stopping to pedal 2 simultaneously, can play the effect of reinforcing pedal 2's structural stability and bearing capacity.

In some embodiments, the frame 1 is provided with a protruding part 11, the protruding part 11 protrudes below the frame 1, and the first connecting rod 41 and the second connecting rod 42 are both rotatably connected with the protruding part 11. For example, as shown in fig. 6 and 7, the protruding portion 11 may be integrally formed and disposed below the frame 1, and the first connecting rod 41 and the second connecting rod 42 may be rotatably connected to the protruding portion 11, where the protruding portion 11 is integrally located in a circumferential range of the swing of the first connecting rod 41 and the second connecting rod 42, so that the condition that the frame 1 easily limits the swing range of the first connecting rod 41 and the second connecting rod 42 can be avoided, and swing adjustment of the first connecting rod 41 and the second connecting rod 42 is facilitated.

In some embodiments, the driving assembly 3 includes a driver 31, a worm 32, and a driving shaft 33, wherein a driving shaft of the driver 31 is connected to the worm 32 and is used for driving the worm 32 to rotate, one end of the driving shaft 33 is engaged with the worm 32 through a gear, the other end of the driving shaft 33 is connected to a second link 42, and the second link 42 is swingable around the driving shaft 33.

The drive shaft 33 is rotatably mounted to the frame 1 and may form a pivot for rotation of the second link 42, as shown particularly in fig. 6.

When the swing driving device is used, the driver 31 can drive the worm 32 to rotate, the rotating worm 32 can drive the gear and the transmission shaft 33 to rotate, and further the rotation driving of the second connecting rod 42 can be realized, so that the swing driving of the connecting rod mechanism 4 is realized. When the driver 31 stops working, the worm 32 and the gear can realize self-locking, so that the second connecting rod 42 can be kept at a swinging position, and the dead point position of the connecting rod mechanism 4 is combined to play a double protection role, so that the bearing function of the pedal 2 is ensured.

The connecting member 43 may have a rod shape, one end of the connecting member 43 may be hinged with the slider 35, and the other end of the connecting member 43 may be hinged with the pedal 2.

When the bicycle frame is used, the driver 31 can drive the screw rod 34 to rotate, the sliding block 35 can move back and forth along the screw rod 34 due to the threaded fit of the sliding block 35 and the screw rod 34, so that the distance between the sliding block 35 and the pedal 2 in the front-back direction can be adjusted, the connecting piece 43 can swing due to the change of the distance, the swinging connecting piece 43 can exert pushing or pulling action on the pedal 2 in the width direction (left-right direction) of the bicycle frame 1, and the pedal 2 can be switched to the first position or the second position.
