As shown in fig. 10, the reduction gear unit 32 and the pushing unit 33 are disposed between the brake caliper 34 and the motor 31. In this embodiment, the motor 31, the reduction gear unit 32 and the pushing unit 33 are assembled on the brake caliper 34. As shown in fig. 4, in the present embodiment, the motor 31 is located above the line L connecting the rear wheel axle center 41 of the rear wheel 4 and the swing center 21 of the rear swing arm 2, so that the motor 31 can be kept away from the mud on the ground and can be prevented from being hit by crushed stones, and the space of the brake disc 1 can be effectively utilized and the overall electronic parking brake apparatus 3 can be miniaturized.

As shown in fig. 3, when the motorcycle is viewed from a side view, the motor 31 is located in front of the reduction gear unit 32, and at least a portion of the motor 31 overlaps the brake disc 1, so that the motor 31 can be separated from the mud on the ground and can be prevented from being hit by debris, and the space of the brake disc 1 can be effectively utilized and the overall electronic parking brake device 3 can be miniaturized.

As shown in fig. 10 and 12, in the present embodiment, the brake caliper 34 includes a caliper body 340, a piston 341, and two spaced brake pads 342, 343. The caliper body 340 has a cylinder hole 3401, and a brake oil passage 3402 communicating with the cylinder hole 3401. The motor 31 is used for providing the power required by the piston 341 to push the brake pads 342, 343, and then the reduction gear unit 32 can reduce the rotation speed provided by the motor 31 to increase the rotation torque to drive the pushing unit 33, so that the pushing unit 33 can push the piston 341, and when the brake pads 342, 343 are pushed by the piston 341, the brake disc 1 can be clamped.

In the present embodiment, the reduction gear unit 32 includes a gear housing 320, a driving gear 321, a first gear set 322, a second gear set 323, and an output gear 324. The gear housing 320 houses the driving gear 321, the first gear set 322, the second gear set 323, and the output gear 324, wherein the driving gear 321 can be driven by the motor 31.

The first gear set 322 has a first gearwheel 3221 driven by the driving gear 321, and a first pinion 3222 rotating coaxially with the first gearwheel 3221 and having a diameter smaller than that of the first gearwheel 3221. In this embodiment, the brake disc 1 and the first pinion 3222 are located on opposite sides of the first gearwheel 3221.

The second gear set 323 has a second large gear 3231 driven by the first small gear 3222 of the first gear set 322, and a second small gear 3232 rotating coaxially with the second large gear 3231 and having a diameter smaller than that of the second large gear 3231. In the embodiment, the second gear set 323 is opposite to the first gear set 322, that is, in the case that the brake disc 1 and the first pinion 3222 are located on the opposite side of the first gearwheel 3221, the second gearwheel 3231 and the brake disc 1 are located on the opposite side of the second pinion 3232, that is, the first pinion 3222 and the second gearwheel 3231 are located outward, so that the arrangement of the motor 31 and the brake caliper 34 is not easily interfered. In the present embodiment, the output gear 324 is driven by the second pinion 3232 of the second gear set 323.

As shown in fig. 8 and 11, the first gear set 322 and the second gear set 323 are disposed between the driving gear 321 and the output gear 324. In addition, the driving gear 321, the first gear set 322, the second gear set 323 and the output gear 324 are arranged substantially along an arc C such that the gear housing 320 forms an inwardly recessed space 3201 facing the center of the brake disc 1.

The fixing frame 35 is used for installing the brake caliper 34 and has at least one fixing screw hole 351, 354 and an accommodating portion 352. As shown in fig. 5, 8 and 10, in the present embodiment, the fixing frame 35 has two fixing screw holes 351 and 354 spaced apart from each other and corresponding to the screws 61 and 62, respectively, and the fixing frame 35 can be locked to the connecting seat 23 of the rear swing arm 2 by locking the screws 61 and 62 to the fixing screw holes 351 and 354, respectively. When the motorcycle is viewed from the side view, the screws 61 and 62 are disposed between the reduction gear unit 32 and the rear wheel axle 5, so as to reduce the space occupied by the electronic parking device 3 and to make the configuration of the whole electronic parking device 3 compact.

As shown in fig. 10, in the present embodiment, the receiving portion 352 is substantially L-shaped in cross section and defines a receiving space 353, wherein a portion of the motor 31 is disposed in the receiving space 353, so as to achieve the effect of reducing the volume of the electronic parking device 3 in the front-back direction and the left-right direction.

As shown in fig. 10 and 12, in the present embodiment, the pushing unit 33 includes an adjusting screw 331 and an adjusting nut 332. The adjusting screw 331 is rotated by the output gear 324. The adjusting nut 332 and the adjusting screw 331 are screwed by a thread portion 330 and are driven by the adjusting screw 331 to move, wherein in the present embodiment, the thread portion 330 is a trapezoidal thread to provide a large enough friction force to achieve a Lock effect, so that there is no relative movement between the adjusting screw 331 and the adjusting nut 332 after the motor 31 is powered off.

The piston 341 is disposed in the cylinder hole 3401 and can be pushed by the adjusting nut 332. In this embodiment, piston 341 has a pushing wall 3412 for pushing brake pads 342 and a surrounding wall 3413 extending from pushing wall 3412 in a direction away from brake pads 342, 343, wherein pushing wall 3412 and surrounding wall 3413 together define a receiving space 3414 for receiving adjustment screw 331 and adjustment nut 332 and communicating with cylinder bore 3401.

As shown in fig. 5 and 12, the brake oil passage 3402 communicates with the cylinder bore 3401 and the accommodating space 3414. The brake oil is injected into the accommodating space 3414 through the brake oil pipe 8 and the brake oil passage 3402 to push the piston 341. In the embodiment, since the hydraulic brake and the electronic parking share the same brake caliper 34 and the same piston 341, the cost can be saved and the space occupation can be reduced, and the brake oil pipe 8 is located above the motor 31 and the reduction gear unit 32, so that the brake oil pipe 8 can be prevented from being knocked by broken stones.

As shown in fig. 9 and 10, when a motorcycle rider wants to electronically park a vehicle, the motor 31 is started to rotate forward to drive the reduction gear unit 32 to rotate, the adjustment screw 331 is rotated to push the adjustment nut 332, and the piston 341 is pushed forward by pushing the pushing wall 3412 of the piston 341, so that the braking shoes 342 and 343 can be pushed by the piston 341, and the braking shoes 342 and 343 can clamp the braking disc 1. Conversely, the motorcycle rider can also reverse the motor 31 to move the adjusting nut 332 backward to release the piston 341 so that the brake shoes 342, 343 no longer brake the brake disc 1. Furthermore, if the motor 31 is powered off when the brake shoes 342, 343 clamp the brake disc 1, the screw portion 330 is a trapezoidal thread to provide a sufficient friction force, so that the adjustment screw 331 and the adjustment nut 332 are automatically maintained in a locked (Lock) state without relative movement, so that the motorcycle can be automatically maintained in an electronic parking state.

As shown in fig. 5, 9 and 12, or when the motorcycle rider wants to perform hydraulic braking, the brake oil is injected into the accommodating space 3414 through the brake oil pipe 8 and the brake oil passage 3402 in sequence by operating a brake device (not shown) to push the piston 341, so as to drive the brake shoes 342, 343, so that the brake shoes 342, 343 clamp the brake disc 1.
