[0046] The steering bracket body 10 is provided with a connecting groove 110, and a connecting hole 120 is provided at the bottom of the connecting groove 110. The steering bracket body 10 is also provided with a damping groove 130, which is connected to the connecting groove 110. The connecting groove 130 is a circular groove, the connecting hole 120 is a circular hole, and the damping groove 130 is a rectangular groove.

[0047] The wheel assembly 20 and the locking assembly 30 are respectively arranged on both sides of the connecting groove 110, and the wheel assembly 20 and the locking assembly 30 are fixedly connected through the connecting hole 120. When the wheel assembly 20 rotates, it can drive the locking assembly 30 to rotate. The rotation of the wheel assembly 20 in this application refers to the following: Figure 1 The steering rotation shown by the dotted arrow is not the rolling of the wheel. The damping assembly 40 is arranged in the damping groove 130 on the steering bracket body 10 and contacts the locking assembly 30. When the locking assembly 30 rotates, the damping assembly 40 can provide elastic damping force for the locking assembly 30.

[0048] The specific implementation structure is:

[0049] The wheel assembly 20 includes a steering wheel 220 and a wheel frame 230 . The steering wheel 220 is hinged to the wheel frame 230 . The wheel frame 230 is provided with a light hole 210 and a synchronization groove 240 .

[0050] The locking assembly 30 includes a locking base 330 and a locking core 340. The locking base 330 is provided with a through-hole locking hole 3310. The locking core 340 is provided with a damping portion 3410 and a locking portion 3420. The locking portion 3420 is assembled within the locking hole 3310, and the damping portion 3410 extends out of the locking hole 3310. The locking core 340 is provided with a screw hole 310, and the locking portion 3420 is provided with a synchronization mechanism 320. The synchronization mechanism 320 extends out of the locking hole 3310.

[0051] Cap screw 50 passes through aperture 210 and connecting hole 120 and is screwed into screw hole 310. Simultaneously, synchronizing structure 320 passes through connecting hole 120 and enters synchronizing groove 230. The synchronizing groove is a non-circular groove, in this embodiment a rectangular groove. The shape and dimensions of the embedded portion of synchronizing structure 320 match those of synchronizing groove 240. Synchronizing structure 320 and synchronizing groove 230 prevent asynchronous steering movements between wheel assembly 20 and locking assembly 30.

[0052] The damping assembly 40 includes a damping head 410, an elastic member 420, and a cover plate 430. Both the damping head 410 and the elastic member 420 are disposed within the damping groove 130. The damping head 410 is pressed against the damping portion 3410 by the elastic force of the elastic member 420. The elastic member 420 may be a spring and / or a spring.

The first convex arc portion 3411 and the second convex arc portion 3412 are smoothly connected through the concave arc portion 3413 , and the damping head 410 rests on the concave arc portion 3413 .

[0054] When the wheel assembly 20 rotates, it drives the locking core 340 of the locking assembly 30 to rotate synchronously. At this time, the first convex arc portion 3411 or the second convex arc portion 3412 will apply a certain pressure to the damping head 410. After the damping head 410 is under pressure, it presses the elastic member 420 to generate an elastic force. The elastic force of the elastic member 420 reacts to the damping portion 3410 through the damping head 410, thereby increasing the steering damping force of the wheel assembly 20. When the locking core 340 rotates with the wheel assembly 20, the locking seat 330 may remain stationary or rotate under the influence of the friction between it and the locking core 340. Therefore, the description in the claims of this application: the wheel assembly (20) can drive the locking assembly (30) to rotate when it rotates means that when the wheel assembly 20 rotates, it can drive the locking core 340 of the locking assembly 30 to rotate synchronously, and may also drive the locking seat 330 to rotate.
