[0026] The utility model provides Figure 1-6 The electric bicycle brake device shown in the figure includes a brake handle 1, a pump box 2 for storing hydraulic oil is provided on the top of the brake handle 1, a pump cover 3 for closing the pump box 2 is provided on the top of the pump box 2, and a mounting bolt 4 for mounting the brake handle 1 and the pump box 2 is provided on the top of the pump cover 3, and further includes:

[0027] A protective cover 5 is used to protect the mounting bolts 4 from being eroded by rainwater;

[0028] The locking mechanism 6 is provided on the side of the protective cover 5 and is used for installing the protective cover 5 and the pump cover 3;

[0029] The pushing piece is used to push the locking mechanism 6 , and the pushing piece is arranged inside the protective cover 5 .

[0030] Specifically, a mounting groove for mounting the locking mechanism 6 is provided on a side of the protective cover 5 , and a circular groove is provided on one side of an inner wall of the mounting groove for mounting the pushing member.

[0031] Furthermore, the straight direction of the two mounting bolts 4 is the length direction of the pump cover 3, and the length of the inner wall of the protective cover 5 corresponds to the length of the pump cover 3. Therefore, after the protective cover 5 is mounted on the outside of the pump cover 3, the protective cover 5 cannot be moved along the long side direction. The width of the inner wall of the protective cover 5 is the sum of the width of the pump cover 3 plus the length of the locking block 61 extending out of the inner wall of the protective cover 5, so that the protective cover 5 can move along the width direction to facilitate the installation of the locking block 61 and the pump cover 3. The mounting groove runs through the side of the protective cover 5, and the length of the mounting groove is twice the width of the end of the locking block 61. The diameter of the circular groove is 1.2 times the outer diameter of the pushing spring 7.

[0032] Specifically, the locking mechanism 6 includes a locking block 61, one end of the locking block 61 is connected to the mounting groove, and a slot for inserting the other end of the locking block 61 is provided on the side of the mounting bolt 4. The horizontal cross-sections of the locking block 61 and the slot are both L-shaped, and the top and bottom ends of the locking block 61 are respectively fixedly connected to guide blocks 62, and the top and bottom ends of the inner wall of the mounting groove are respectively provided with guide grooves, and the guide block 62 is slidably connected to the guide groove, and one end of the locking block 61 is fixedly connected to a push plate 63, and the side of the push plate 63 away from the locking block 61 is provided with an anti-skid groove 64 for preventing slipping, and the end of the mounting groove away from the mounting bolt 4 is provided with an outer frame, and the push plate 63 is slidably connected to the outer frame.

[0033] When the locking block 61 is in the unlocking state, the locking block 61 is locked and the locking block 61 is locked.

[0034] Specifically, the pushing member includes a pushing spring 7 , one end of the pushing spring 7 is inserted and connected with the circular groove, and the other end of the pushing spring 7 is fixedly connected with the outer wall of the locking block 61 .

[0035] Furthermore, the pushing spring 7 is always in a compressed state in the installation groove, thereby always pushing the locking block 61 to move away from the circular groove. The two ends of the pushing spring 7 are respectively fixed to the inner wall of the circular groove and the outer wall of the locking block 61 by bonding. When the locking block 61 is inserted into the slot, the restoring force of the pushing spring 7 pushes the locking block 61, so that the locking block 61 is plugged into the slot. Under the action of the locking block 61, the protective cover 5 cannot move, so that the protective cover 5 is stably installed on the outside of the pump cover 3, protecting the mounting bolts 4 and preventing rainwater erosion.
