The first shaft 31 extends in the front-rear or up-down direction. Preferably, the driving wheel 41 is driven to rotate by a motor 42, the motor 42 is fixedly arranged on the second component 200, the driving wheel 41 is sleeved on a motor shaft of the motor 42 and rotates synchronously with the motor shaft, and when the motor 42 is started, the driving wheel 41 is driven to rotate relative to the second component 200. Therefore, the brake mechanism is an electric brake mechanism, and the brake or the brake release is easy. When braking, the motor 42 drives the driving wheel 41 to rotate, and drives the brake pin assembly 2 to slide towards the direction close to the brake disc 1 relative to the second component 200 through the connecting structure until the brake pin assembly is matched with the brake disc 1; when the brake is released, the motor 42 drives the driving wheel 41 to rotate reversely, and the brake pin assembly 2 is driven to slide relative to the second component 200 in a direction away from the brake disc 1 through the connecting structure until the brake pin assembly is disengaged from the brake disc 1.

The second shaft 32 and the third shaft 33 are both disposed in parallel with the first shaft 31 and also extend in the front-rear or up-down direction. When the motor 42 drives the driving wheel 41 to rotate, the driving link 5 swings relative to the second member 200, thereby sliding the brake pin assembly 2 relative to the second member 200.

During braking, the second resilient member 24 is compressed. When the brake is released, the motor 42 drives the driving wheel 41 to rotate reversely, the slide block 22 is driven by the connecting rod 5 to slide in a direction away from the brake disc 1 relative to the second component 200, the slide block 22 slides to release the elasticity of the first elastic element 23, and after the elasticity of the first elastic element 23 is released to a certain degree, the second elastic element 24 drives the brake pin 21 to slide in a direction away from the brake disc 1 relative to the second component 200; when the brake pin 21 slides for a certain distance but is not reset to the initial state, the motor 42 stops driving the driving wheel 41 to rotate in the reverse direction, and at this time, the brake pin 21 can continue to slide relative to the second member 200 in the previous sliding direction under the elastic force of the second elastic member 24 until the brake pin 21 is completely released from the brake slot 11, and the brake mechanism is in the brake release state, and the first member 100 and the second member 200 can move relative to each other, as shown in fig. 10 to 13.

Furthermore, during braking, impact caused by direct contact between the brake pin 21 and the brake disc 1 when the brake pin 21 cannot be aligned with the brake groove 11 of the brake disc 1 can be avoided.
Example 2
As shown in fig. 15 and 16, in this embodiment, the brake pin assembly 2 includes a brake pin 25 slidably disposed on the second member 200, and an end of the brake pin 25 is indirectly connected to the driving wheel 41 through a connection structure. When the link 5 is adopted as the connection structure, the other end portion of the link 5 is rotatably connected to one end portion of the brake pin 25 through the third shaft 33. The brake disc 1 is provided with a plurality of brake grooves 11, and the brake grooves 11 are arranged at intervals along the direction of relative movement of the first member 100 and the second member 200.

The rest is the same as in example 1.
In this embodiment, when braking, the motor 42 drives the driving wheel 41 to rotate in a forward direction, and the connecting rod 5 drives the brake pin 25 to slide relative to the second member 200 in a direction approaching the brake disc 1 until the other end of the brake pin 25 is inserted into the brake slot 11, so that the braking mechanism is in a braking state, and the first member 100 and the second member 200 cannot move relative to each other. When the brake is released, the motor 42 drives the driving wheel 41 to rotate reversely, the connecting rod 5 drives the brake pin 25 to slide in the direction away from the brake disc 1 relative to the second component 200 until the brake pin 25 is completely released from the brake slot 11, the brake mechanism is in the release state, and the first component 100 and the second component 200 can move relatively. In this embodiment, the movement of the brake pin 25 is driven by the drive wheel 41 during both braking and braking. Compared to embodiment 1, the structure of the brake pin assembly 2 of this embodiment may cause a problem of impact generated by direct contact between the brake pin 25 and the brake disc 1 when the brake pin 25 is not aligned with the brake groove 11 of the brake disc 1 during braking.
Example 3

Specifically, the driving wheel 41 is provided with teeth 411, the brake pin assembly 2 is provided with a rack 221 extending along the length direction thereof, and the teeth 411 are engaged with the rack 221. Thus, when the brake mechanism is braked from the brake-off state, the motor 42 drives the driving wheel 41 to rotate, and the brake pin assembly 2 is driven to slide towards the brake disc 1 relative to the second component 200 through the meshing motion of the teeth 411 and the rack 221 until the brake mechanism is matched with the brake disc 1; when the brake mechanism is released from the braking state, the motor 42 drives the driving wheel 41 to rotate reversely, and the engagement movement of the teeth 411 and the rack 221 drives the brake pin assembly 2 to slide relative to the second member 200 in a direction away from the brake disc 1 until the engagement with the brake disc 1 is released. In this embodiment, the structure of the brake pin assembly 2 is the same as that of embodiment 1 except that one end portion of the slider 22 is provided with the rack 221.
Example 4
In this embodiment, as shown in fig. 18, the driving wheel 41 and the brake pin assembly 2 are directly connected, and when the driving wheel 41 rotates around the first shaft 31, the distance between the connection point of the driving wheel 41 and the brake pin assembly 2 and the brake disc 1 changes, so that the distance between the brake pin assembly 2 and the brake disc 1 changes, and the brake mechanism is braked or released.
Specifically, the driving wheel 41 is provided with teeth 411, the brake pin assembly 2 is provided with a rack 251 extending along the length direction thereof, and the teeth 411 are engaged with the rack 251. Thus, when the brake mechanism is braked from the brake-released state, the motor 42 drives the driving wheel 41 to rotate, and the teeth 411 and the rack 251 are engaged to move, so that the brake pin assembly 2 is driven to slide relative to the second component 200 in the direction approaching the brake disc 1 until the brake pin assembly is matched with the brake disc 1; when the brake mechanism is released from the braking state, the motor 42 drives the driving wheel 41 to rotate reversely, and the engagement movement of the teeth 411 and the rack 251 drives the brake pin assembly 2 to slide relative to the second member 200 in a direction away from the brake disc 1 until the engagement with the brake disc 1 is released. In this embodiment, the structure of the brake pin assembly 2 is the same as that of embodiment 2 except that one end portion of the brake pin 25 is provided with the rack 251.

The sliding of the brake pin assembly 2 is guided by the engagement of the slide groove 201 with the brake pin assembly 2 during the sliding of the brake pin assembly 2 relative to the second member 200.

When the driving wheel 41 rotates relative to the second member 200, the second shaft 32 is driven to move in the arc-shaped groove 202 along the length extension direction of the arc-shaped groove 202; when the second shaft 32 abuts against one end of the arc-shaped groove 202, the driving wheel 41 cannot rotate continuously in the current direction, but can rotate reversely.
During the forward rotation braking of the driving wheel 41, the second shaft 32 has a dead point position where the axial center of the first shaft 31, the axial center of the second shaft 32 and the axial center of the third shaft 33 are in the same straight line extending direction, and the arc-shaped groove 202 extends along the rotation direction of the driving wheel 41 and passes through at least the dead point position. In this embodiment, one end of the arc-shaped slot 202 goes beyond the dead point position, and when the brake mechanism is braking, the second shaft 32 slides in the arc-shaped slot 202 from the other end of the arc-shaped slot 202 to a direction close to the one end of the arc-shaped slot 202 and goes beyond the dead point position; when the brake mechanism is in the braking state, the second shaft 32 is positioned at one end of the arcuate slot 202 in the arcuate slot 202, as shown in FIG. 5.
