DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides Figures 1-4 The hydraulic brake of an electric bicycle shown comprises a brake handle 1, and also includes:

[0026] The handle assembly 2 includes a handle seat 202 disposed on one side of the brake handle 1, and a push handle 201 is disposed on one side of the handle seat 202;

[0027] Anti-skid bumps 3, which are arranged on the front of the push handle 201, and are used to increase the friction between the push handle 201 and the hand;

[0028] A connecting component 5, which is disposed at the connection between the push handle 201 and the handle base 202, and is used to limit the movement of the push handle 201;

[0029] The clamping assembly 6 is arranged at the connection between the push handle 201 and the handle seat 202 , and the clamping assembly 6 is used for installing and removing the push handle 201 .

[0030] It should be noted that the handle is divided into a push handle 201 and a handle seat 202. The anti-skid protrusion 3 is set on the push handle 201. The design of the anti-skid protrusion 3 increases the contact area between the handle and the finger, thereby increasing the friction and avoiding the finger from slipping on the handle. When the handle needs to be pulled to one side of the handle, the finger is first moved to the front of the push handle 201 and contacts the anti-skid protrusion 3, and the push handle 201 is pulled to one side of the handle to complete the braking action.

[0031] Specifically, an oil pipe 10 is provided on one side of the brake handle 1, a brake 11 is provided at one end of the oil pipe 10, and an installation assembly 4 for fixing the position of the brake handle 1 is provided on the back of the brake handle 1.

[0032] It should be noted that the brake handle 1, the oil pipe 10 and the brake 11 are arranged in the same working principle as the piston hydraulic disc brake of model BL-M7020.

[0033] Specifically, the installation assembly 4 includes a mounting seat 401 fixedly connected to the back of the brake handle 1. A rotating seat 402 is hinged to the back of the mounting seat 401, and a bolt 403 for restricting the rotation of the rotating seat 402 is provided at the bottom of the rotating seat 402.

[0034] It should be noted that arc-shaped grooves are formed on the opposite sides of the mounting seat 401 and the rotating seat 402. When the position of the brake handle 1 needs to be installed on the electric bicycle, first, the mounting seat 401 is sleeved on one side of the handlebar through the arc-shaped groove, then the rotating seat 402 is rotated so that the rotating seat 402 is sleeved on one side of the electric bicycle handlebar through the arc-shaped groove. Finally, the bolt 403 passes through the mounting seat 401 and the rotating seat 402 in sequence to fix the mounting seat 401 and the rotating seat 402, and fix the mounting seat 401 and the rotating seat 402 on one side of the electric bicycle handlebar.

[0035] Specifically, the connecting assembly 5 includes a connecting block 502 fixedly connected to one side of the handle seat 202. A connecting groove 501 is formed on one side of the pressing handle 201. The connecting block 502 is inserted into the connecting groove 501. The clamping assembly 6 includes a clamping hole 601 formed on the inner wall of the top end of the connecting groove 501. A clamping block 602 is inserted into the clamping hole 601. A pushing member 7 for driving the clamping block 602 to move is provided at the bottom of the clamping block 602. The pushing member 7 includes a pushing block 701 fixedly connected to the bottom end of the clamping block 602. A resilient block 702 is fixedly connected to the bottom end of the pushing block 701. The horizontal longitudinal section of the resilient block 702 is an isosceles trapezoid. A cavity 703 is formed in the middle of the connecting block 502. The pushing block 701 is inserted into the cavity 703. The resilient block 702 is fixedly connected to the inner wall of the bottom end of the resilient block 702. A through hole 9 is formed on the inner wall of the top end of the cavity 703. The clamping block 602 is inserted into the through hole 9. A guiding member 8 for restricting the shaking of the pushing block 701 is provided in the cavity 703.

[0036] It should be noted that the provided connecting block 502 is adapted to the provided connecting groove 501. The shape of the provided connecting block 502 is a cube to prevent the connecting block 502 from rotating inside the connecting groove 501. The provided clamping block 602 is connected to the pushing block 701 located inside the cavity 703 through the provided through hole 9. The horizontal cross-sectional area of the pushing block 701 is larger than the horizontal cross-sectional area of the through hole 9, so that the pushing block 701 cannot pass through the through hole 9 and out of the cavity 703. Thus, when the pushing block 701 moves to fit against the inner wall at the top of the cavity 703, it will be blocked by the inner wall at the top of the cavity 703 and cannot continue to move. When it is necessary to limit the connecting block 502 inside the connecting groove 501, the clamping block 602 is inserted into the clamping hole 601 opened on the inner wall at the top of the connecting groove 501. When the clamping block 602 is inserted into the clamping hole 601, its bottom end is still inside the through hole 9. Thus, due to the blocking of the clamping block 602, the connecting block 502 cannot continue to move. The provided elastic block 702 is made of rubber material, and the rubber material has the characteristic of being deformable. When the elastic block 702 is squeezed by the pushing block 701, the elastic block 702 will deform, enabling the pushing block 701 to continue moving towards the side of the elastic block 702. When the elastic block 702 loses the downward pressing force of the pushing block 701, the elastic block 702 will recover its deformation and push the pushing block 701 towards the side of the clamping block 602. Through the design of the elastic block 702 with a special shape, space is reserved for the deformation of the elastic block 702.

[0037] Specifically, the guiding member 8 includes guiding holes 802 symmetrically opened on both sides of the pushing block 701. A guiding rod 801 is inserted and connected inside the guiding holes 802. Both ends of the guiding rod 801 are fixedly connected to the inner walls at the top and bottom of the cavity 703 respectively.

[0038] It should be noted that the number of the provided guiding rods 801 is at least two. A plurality of guiding rods 801 are arranged in parallel. The number of the opened guiding holes 802 is the same as the number of the provided guiding rods 801. During use, the pushing block 701 is sleeved on the middle part of the guiding rod 801 through the opened guiding holes 802. When the pushing block 701 moves, it moves along the direction of the guiding rod 801. And through the design of a plurality of guiding rods 801 with fixed positions, the pushing block 701 cannot tilt to one side.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
