Description

Technical Field

[0001] The utility model relates to the field of brake devices, in particular to an electric motorcycle stable brake device. Background Art

[0002] The brake system is a mechanical braking device that can slow down the vehicle, also known as a decelerator. The brake system achieves the deceleration effect by generating friction between the brake pads and the wheel drum or disc. Common brake systems include "drum brakes" and "disc brakes". Drum brakes are cheaper, have higher absolute braking force, and have more stable braking effects. Therefore, most of the brakes on the market are "drum brakes".

[0003] In the prior art, the brake pads on the drum brake device will inevitably age and be damaged after a period of use, so the brake pads need to be replaced. However, one brake pad is usually installed on the supporting shell, and the other is installed on the piston inside the supporting shell. When the brake pads need to be replaced, the supporting shell needs to be separated. The supporting shells on the market are usually connected by bolts, so it is necessary to use a suitable wrench or other tool to unscrew the bolts before the shells can be separated, which is relatively inconvenient. Therefore, a stable brake device for an electric motorcycle is needed. Utility Model Content

[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art and provide an electric motorcycle stable brake device. By arranging structures such as a rotating block, a fixing groove and a T-block, when it is necessary to replace the brake pads in the first bearing shell and the second bearing shell, the rotating block is rotated to release the fixation between the first bearing shell and the second bearing shell. There is no need to use a wrench or other tools to unscrew the bolts to achieve the disassembly work between the first bearing shell and the second bearing shell. The utility model is simple and quick. When the brake pads are replaced and the first bearing shell and the second bearing shell need to be connected and fixed, the positioning block is inserted into the docking groove and then the fixing groove is inserted into the T-block. The connection and fixation between the first bearing shell and the second bearing shell can be achieved conveniently and quickly. By arranging structures such as the positioning block and the docking groove, when connecting the first bearing shell and the second bearing shell, the positioning block is inserted into the docking groove, which not only achieves the preliminary connection between the first bearing shell and the second bearing shell, but also makes the fixing groove and the T-block correspond to each other, thereby facilitating the subsequent operation of the maintenance personnel and saving time and effort.

[0005] The present invention also provides an electric motorcycle stabilizing brake device as described above, comprising a first bearing shell, a second bearing shell movably connected to the first bearing shell, a limiting block fixedly connected to the side surface of the first bearing shell, a positioning block fixedly connected to the left surface of the limiting block, a docking block fixedly connected to the side surface of the second bearing shell, and a docking groove provided on the docking block.

[0006] The upper surface of the first bearing shell is fixedly connected to a connecting block, the inner surface of the connecting block is rotatably connected to a bidirectional threaded screw, the front surface of the bidirectional threaded screw is fixedly connected to a rotating block, the outer surface of the bidirectional threaded screw is threadedly connected to two sliders, both of the sliders are fixedly connected to a movable block, both of the movable blocks are provided with a fixing groove, and the upper surfaces of the first bearing shell and the second bearing shell are fixedly connected to T-blocks.

[0007] According to the electric motorcycle stabilizing brake device, the outer surface of the positioning block is movably connected to the docking groove, and the number of the limiting blocks is two and they are distributed front to back.

[0008] According to the electric motorcycle stabilizing brake device, the number of the positioning blocks is two and they are distributed front to back, and the number of the docking blocks is two and they are distributed front to back.

[0009] According to the electric motorcycle stabilizing brake device, the rear surface of the rotating block contacts the connecting block, and the left surface of the limiting block contacts the docking block.

[0010] According to the electric motorcycle stabilizing brake device, the bidirectional threaded screw passes through the slider.

[0011] According to the electric motorcycle stabilizing brake device, a sliding groove is provided on the connecting block, and the outer surface of the slider is slidably connected to the sliding groove to limit the moving direction and moving distance of the slider.

[0012] According to the electric motorcycle stabilizing brake device, the outer surface of the fixing groove is movably connected to the T-block.

[0025] Working principle: By rotating the rotating block 9, the rotating rotating block 9 can drive the bidirectional threaded screw 8 to rotate, so that the rotating bidirectional threaded screw 8 drives the two sliders 10 to move away from each other in the slide groove 14 on the connecting block 7, and then the two moving sliders 10 respectively drive the movable block 11 and the fixed groove 12 to move, so that the two movable blocks 11 and the two fixed grooves 12 move away from each other. When the movable fixed groove 12 is separated from the T-block 13, the fixation between the first bearing shell 1 and the second bearing shell 2 is released, and then the first bearing shell 1 and the second bearing shell 2 are pulled to both sides, so that the first bearing shell 1 and the second bearing shell 2 can be separated, and then the brake pads inside the first bearing shell 1 and the second bearing shell 2 can be replaced. When the first bearing shell 1 and the second bearing shell 2 are separated, the brake pads inside the first bearing shell 1 and the second bearing shell 2 can be replaced. After the brake pads on the first bearing shell 1 and the second bearing shell 2 are replaced, the positioning block 4 on the limit block 3 is inserted into the docking groove 6 on the docking block 5, so that the preliminary connection between the first bearing shell 1 and the second bearing shell 2 can be achieved, and the fixing groove 12 can correspond to the T-block 13. Then, the rotating block 9 is rotated in the opposite direction, so that the bidirectional threaded screw 8 can be rotated, and the rotating bidirectional threaded screw 8 can drive the two sliders 10 to move closer to each other, so that the two moving sliders 10 can respectively drive the two movable blocks 11 and the two fixed grooves 12 to move closer to each other. When the movable fixed groove 12 is inserted into the T-block 13, the fixation between the first bearing shell 1 and the second bearing shell 2 is completed, so that the first bearing shell 1 and the second bearing shell 2 can no longer be separated.
