The end of the control lever 101 has an anti-slip sleeve 1011 for the user to hold and stably operate the control lever, thereby facilitating riding of the bicycle.

Referring to fig. 2, the lever 101 is provided with an outlet 1012, from which outlet 1012 a push rod 1013 of the oil brake can be seen. The brake compensation structure 102 can enter the outlet 1012 to push the push rod 1013 so as to drive the oil brake to work through the push rod 1013, thereby controlling the oil brake to brake the bicycle. As for the push rod 1013 driving the oil brake to work, the oil brake is controlled to make the plate friction wheel, which is already mature prior art in the field, and redundant description is not needed in the present utility model.

The lever 101 is uniformly provided with a plurality of rivets 1014 (shown in fig. 1) along a circumferential side thereof, and the rivets 1014 penetrate a side wall of the lever 101 to connect the oil brake for mounting and fixing the oil brake.

Referring to fig. 3 and 4, the brake compensating structure 102 includes a mounting mechanism 1 and a driving mechanism 2, the driving mechanism 2 is rotatably connected to the mounting mechanism 1, and the mounting mechanism 1 is configured to be detachably coupled to the lever 101, so that the driving mechanism 2 is mounted on the lever 101. When the mounting mechanism 1 is mounted and secured, the drive mechanism 2 is capable of pressing against the push rod 1013 to actuate the movement of the bicycle to brake.

The mounting mechanism 1 comprises a first mounting piece 11, a second mounting piece 12, a first screw 13, a second screw 14 and a mounting screw 15, wherein the first screw 13 and the second screw 14 are respectively penetrated from two sides of the first mounting piece 11 and then are in threaded connection. It will be appreciated that the first screw 13 and the second screw 14 are screwed together to form a rotating rod to be mounted on the first mounting member 11. The first mounting member 11 is connected to the second mounting member 12 by mounting screws 15.

The first mounting piece 11 and the second mounting piece 12 are all U-shaped, and after the first mounting piece 11 and the second mounting piece 12 are connected through two mounting screws 15, a mounting hole 16 is formed between the first mounting piece 11 and the second mounting piece 12, and the mounting mechanism 1 can be sleeved on the control rod 101 through the mounting hole 16. When the installation mechanism 1 needs to be disassembled, the two installation screws 15 can be disassembled, namely the first installation piece 11 and the second installation piece 12 can be separated, and then the operation rod 101 is disassembled, so that the disassembly and the assembly are rapid and convenient, and the user experience is good.

The first mounting member 11 is provided with a receiving cavity 111, and the receiving cavity 111 is mainly used for receiving the driving mechanism 2. The first screw 13 is disposed across the accommodating chamber 111, and the driving mechanism 2 is coupled to the first screw 13 so as to be rotatable about the first screw 13 relative to the first mounting member 11. It should be emphasized that when the first mounting member 11 and the second mounting member 12 are sleeved on the lever 101, the accommodating chamber 111 is in communication with the outlet 1012 of the lever 101, such that the driving mechanism 2 located in the accommodating chamber 111 can press the push rod 1013 driving the oil brake to move, so as to brake the bicycle.

The first mounting piece 11 is provided with sinking grooves 112 on two opposite sides, and the sinking grooves 112 on two sides are respectively used for limiting the first screw 13 and the second screw 14. The first screw 13 and the second screw 14 are hexagonal screws, and two hexagonal wrenches can be used to insert into the first screw 13 and the second screw 14 respectively, and then drive the first screw 13 and the second screw 14 to rotate reversely, so that the first screw 13 and the second screw 14 can be installed and fixed.

The driving mechanism 2 comprises a handle 21, a driving piece 22, an adjusting screw 23 and a torsion spring 24, wherein one end of the driving piece 22 is positioned in the handle 21, the adjusting screw 23 is in threaded connection with the handle 21, and the torsion spring 24 is positioned at the side of the handle 21.

The handle 21 has an arc-shaped driving portion 211, and the driving portion 211 can be squeezed by a user's hand so as to apply a force to the handle to drive the handle 21 to rotate.

The left and right sides of handle 21 all has seted up accommodation notch 212, and accommodation notch 212 is used for supplying torsional spring 24 to place, and the lateral wall of accommodation notch 212 is butt-jointed to torsional spring 24's one end, and the other end butt-joint first mounting 11. When the user presses the handle 21 by hand to drive the handle 21 to rotate, the handle 21 presses the torsion spring 24 to drive the torsion spring 24 to accumulate the elastic force. When the user releases the handle 21, the torsion spring 24 can release the elastic force to drive the handle 21 to rotate reversely to reset, so that the user can drive the handle 21 to rotate again next time.

The torsion springs 24 are provided with two containing notches 212 respectively positioned at two sides of the handle 21.

Referring to fig. 5, a mounting groove 213 is formed at an end of the handle 21 adjacent to the driving member 22, and the mounting groove 213 is used for accommodating the driving member 22 so that the handle 21 drives the driving member 22 to rotate. The mounting groove 213 is open at one side and has a threaded hole 214 at the other side, and the threaded hole 214 is used for being screwed with the adjusting screw 23, so that the adjusting screw 23 drives the driving member 22 to rotate, thereby adjusting the initial position of the driving member 22 away from the end of the handle 21. When the adjusting screw 23 is withdrawn from the mounting groove 213, the handle 21 can press the driving member 22 through the side wall of the mounting groove 213 to drive the driving member 22 to rotate, so that the end of the driving member 22 far away from the handle 21 can press the push rod 1013 of the oil brake.

The handle 21 has first through-holes 215 on both sides, and the first through-holes 215 communicate with the mounting groove 213 and the accommodating notch 212. The first through hole 215 is configured to allow the first screw 13 to pass therethrough, so that the handle 21 can rotate around the first screw 13.

The driving member 22 includes a first end 221 and a second end 222, the first end 221 being the end closer to the handle 21 and the second end 222 being the end farther from the handle 21. The handle 21 can press against the first end 221 or press against the first end 221 through the adjusting screw 23 to drive the driving member 22 to rotate, so that the second end 222 presses against the push rod 1013 of the oil brake. It should be noted that, the second end 222 is inserted through the outlet 1012 of the lever 101 and extends into the lever 101, so as to abut against the push rod 1013 of the oil brake.

The driving piece 22 is provided with a second through hole 223 along the thickness direction, and the driving piece 22 is sleeved on the first screw 13 through the second through hole 223, so that the driving piece 22 can rotate around the first screw 13.

The driving member 22 has two main states:

first, the adjusting screw 23 is withdrawn from the mounting groove 213 of the handle 21, and when the handle 21 is rotated, the handle 21 presses the first end 221 of the driving member 22 through the groove wall of the mounting groove 213, thereby driving the driving member 22 to rotate, and the second end 222 of the driving member 22 presses the push rod 1013 of the hydraulic brake to brake the bicycle.

Second, a part of the adjusting screw 23 is located in the mounting groove 213 of the handle 21, and this situation is mainly that after the oil brake of the bicycle is used for a long time, the push rod 1013 of the oil brake is worn or loosened, and the push rod 1013 needs to be moved for a longer distance to drive the plate to effectively contact the wheel, so that the bicycle is effectively braked. In this case, the user can apply a larger force to the handle 21 to rotate the handle 21 by a larger extent to move the push rod 1013 of the oil brake by the driving member 22 by a longer distance, but this not only makes the user laborious, but also the rotation extent of the handle of some bicycles is limited, and the handle 21 is insufficient to rotate by a larger extent. Thus, the user can manually rotate the adjustment screw 23 such that the adjustment screw 23 is threadedly engaged into the mounting slot 213 of the handle 21 to press against the first end 221 of the driver 22 to rotate the driver 22, with the second end 222 of the driver 22 initially positioned closer to the push rod 1013 of the oil brake. Under the same rotation amplitude of the handle 21, obviously, after the adjustment of the adjusting screw 23, the movement amplitude of the push rod 1013 of the oil brake is larger, so that the driving piece can be driven to be in effective contact with the wheel, and the braking effect of the bicycle is good.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that modifications, substitutions and improvements can be made by those skilled in the art without departing from the spirit of the utility model, and are intended to be within the scope of the utility model. Accordingly, the protection scope of the present utility model is subject to the claims.
