Detailed Description
The technical solution of the present invention will be further explained with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 7, the brake mechanism of the present invention is used to prevent relative movement between a first member 100 and a second member 200, and includes a disc rotor 1 fixedly disposed on the first member 100 and a brake pin assembly 2 slidably disposed on the second member 200. The brake pin assembly 2 can be matched with or separated from the brake disc 1, when the brake mechanism is in a braking state, the brake pin assembly 2 is matched with the brake disc 1, and the first component 100 and the second component 200 cannot move relatively; when the brake mechanism is in the brake release state, the engagement between the brake pin assembly 2 and the brake disc 1 is disengaged, and the first member 100 and the second member 200 can move relatively.
The brake mechanism further comprises a driving wheel 41 rotatably arranged on the second member 200 via a first shaft 31, the brake pin assembly 2 being rotatably connected to the driving wheel 41 via a second shaft 32. The first shaft 31 and the second shaft 32 are arranged in parallel, and both the first shaft 31 and the second shaft 32 extend in the front-rear direction or the 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. The driving wheel 41 is provided with a first sliding slot 411 matched with the second shaft 32, the second shaft 32 is positioned in the first sliding slot 411 and can be arranged in a sliding manner along the length extension direction of the first sliding slot 411, and the distance between each point on the first sliding slot 411 and the axis of the first shaft 31 gradually increases or decreases along the length extension direction of the first sliding slot 411. When the brake mechanism is in a braking state, the distance between the axis of the second shaft 32 and the axis of the first shaft 31 is the largest, and when the brake mechanism is in an unlocking state, the distance between the axis of the second shaft 32 and the axis of the first shaft 31 is the smallest.
Thus, when the brake mechanism is braked from the brake-off state, the motor 42 drives the driving wheel 41 to rotate, so that the second shaft 32 slides in the first sliding slot 411 along the length extension direction of the first sliding slot 411 from the position closest to the shaft center of the first shaft 31, and in the process, the distance from the shaft center of the second shaft 32 to the shaft center of the first shaft 31 is gradually increased, so that the brake pin assembly 2 is driven to slide towards the brake disc 1 relative to the second component 200 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 in the reverse direction, so that the second shaft 32 slides in the first sliding slot 411 along the length extension direction of the first sliding slot 411 from the position farthest from the shaft center of the first shaft 31, and in the process, the distance from the shaft center of the second shaft 32 to the shaft center of the first shaft 31 gradually decreases, so that the brake pin assembly 2 is driven to slide relative to the second member 200 in the direction away from the brake disc 1 until the engagement with the brake disc 1 is released.
The first sliding slot 411 and the second shaft 32 are matched to limit the rotation angle of the driving wheel 41, and when the second shaft 32 abuts against one end of the first sliding slot 411 during the rotation of the driving wheel 41, the driving wheel 41 cannot continue to rotate in the current direction and can only rotate in the reverse direction.
With respect to the specific structure of the brake pin assembly 2, the following two specific embodiments are given in the present application.

The other end portion of the brake pin 21 is inserted into the brake groove 11 when the brake mechanism is in a braking state, and the brake pin 21 is completely released from the brake groove 11 when the brake mechanism is in an unlocking state. The brake pin assembly 2 further includes a second elastic member 24 disposed between the brake pin 21 and the second member 200, and both end portions of the second elastic member 24 are abutted against the brake pin 21 and the second member 200, respectively.

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 sliding block 22 is driven to slide in a direction away from the brake disc 1 relative to the second component 200 through the matching of the first sliding slot 411 and the second shaft 32, the sliding block 22 slides to release the elasticity of the first elastic part 23, and after the elasticity of the first elastic part 23 is released to a certain degree, the second elastic part 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 a certain distance but is not returned 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. 4.

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. 6 and 7, in this embodiment, the brake pin assembly 2 includes a brake pin 25 slidably disposed on the second member 200, and one end of the brake pin 25 is rotatably connected to the driving wheel 41 via the second shaft 32. 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 other end portion of the brake pin 25 is inserted into the brake groove 11 when the brake mechanism is in a braking state, and the brake pin 25 is completely released from the brake groove 11 when the brake mechanism is in an unlocking state.
In this embodiment, when braking, the motor 42 drives the driving wheel 41 to rotate in a forward direction, and the first sliding slot 411 and the second shaft 32 cooperate to drive the brake pin 25 to slide in a direction approaching the brake disc 1 relative to the second member 200 until the other end of the brake pin 25 is inserted into the brake slot 11, so that the brake 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, and the first sliding slot 411 and the second shaft 32 are matched to drive the brake pin 25 to slide relative to the second component 200 in the direction away from the brake disc 1 until the brake pin 25 is completely released from the brake slot 11, so that 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.
