[0023] Please see attached Figure 1-3 The present utility model provides a vehicle braking device, comprising:

[0024] A motor assembly 100, wherein the motor assembly 100 includes a motor 110 and a rotating shaft 120;

[0025] A cylinder body 200, wherein a first cavity 210 and a second cavity 220 are formed in the cylinder body 200, and the cylinder body 200 is provided with a first through hole 230, wherein the first through hole 230 is used for supplying gas or liquid;

[0026] A transmission assembly 300, the transmission assembly 300 includes a sleeve rod 310 and a push rod 320, one end of the sleeve rod 310 is sleeved on the rotating shaft 120 through a threaded connection, the other end of the sleeve rod 310 abuts against the push rod 320, and the push rod 320 is disposed in the second cavity 220; and,

[0027] The caliper assembly 400 includes a caliper seat 410, on which a first brake pad 430 and a second brake pad 420 are provided, and a wheel locking space is formed between the first brake pad 430 and the second brake pad 420. When the push rod 320 applies a thrust in the direction of the caliper seat 410, the push rod 320 pushes the first brake pad 430 to move in a direction close to the second brake pad 420 to brake the vehicle.

[0028] In one embodiment, the automobile braking device of the present application also includes a support sleeve 500, which is disposed in the first cavity 210 and the second cavity 220, and isolates the first cavity 210 and the second cavity 220 from each other, that is, seals the first cavity 210 and the second cavity 220, and the sleeve rod 310 is penetrated by the support sleeve 500, and the support sleeve 500 provides support force and sliding guide function for the sleeve rod 310 and the push rod 320.

[0029] In one embodiment, the motor assembly 100 further includes a reducer 130, and the motor 110 is transmission-connected to the rotating shaft 120 via the reducer 130. The reducer 130 may have a reduction ratio of 3:1 or 10:1 or other reduction ratios, which are not limited herein.
