[0026] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0027] As Figures 1 to 5 shown, the present utility model provides a motorcycle brake pump, which includes a brake pump housing 1. An oil inlet pipe 5 is installed at the top end of the brake pump housing 1. One end of the brake pump housing 1 is provided with a connecting shaft 6. One end of the connecting shaft 6 penetrates through the brake pump housing 1 and extends into the brake pump housing 1. One end of the connecting shaft 6 located inside the brake pump housing 1 is fixedly connected with a piston 24. One end of the connecting shaft 6 located outside the brake pump housing 1 is used to connect a transmission mechanism. A heat dissipation mechanism 2 is provided on the outer surface of the brake pump housing 1. One end of the brake pump housing 1 is fixedly connected with an oil outlet pipe 1 4 through bolts. A clamping mechanism 3 is provided at one end of the oil outlet pipe 1 4. The connecting shaft 6 can effectively transmit power to drive the piston 24 to move to realize the basic function of the brake pump. The setting of the heat dissipation mechanism 2 provides a basis for subsequent heat dissipation, which is beneficial to maintaining the overall working stability of the brake pump.

[0028] The heat dissipation mechanism 2 includes a plurality of heat dissipation fins 22. A plurality of through-type heat dissipation grooves 23 are opened at the bottom end of the brake pump housing 1. The inner surfaces of the plurality of heat dissipation grooves 23 and the outer surfaces of the plurality of heat dissipation fins 22 are fixedly connected by welding respectively. The plurality of heat dissipation fins 22 respectively penetrate through the plurality of heat dissipation grooves 23 and extend into the brake pump housing 1. The cooperation between the heat dissipation fins 22 and the heat dissipation grooves 23 greatly increases the contact area between the brake pump housing 1 and the outside air, and can quickly conduct the heat generated during the operation of the brake pump to the air. The welding fixing method ensures the structural stability, makes the heat dissipation process efficient and stable, and effectively reduces the internal temperature of the brake pump.

[0029] Specifically, the plurality of heat dissipation fins 22 are arranged at equal intervals, and a plurality of through-type cooling grooves 21 are opened at one end of the plurality of heat dissipation fins 22. The heat dissipation fins 22 arranged at equal intervals make the heat dissipation more uniform, avoiding local overheating. The cooling grooves 21 further increase the heat dissipation area, and during the running of the motorcycle, air can flow better in the cooling grooves 21, enhancing the heat dissipation effect.

[0030] As Figures 1 to 5As shown in the figure, the clamping mechanism 3 includes a first connecting pipe 35, which is fixedly sleeved with the first oil outlet pipe 4. A second connecting pipe 31 is sleeved on the outer surface of the first connecting pipe 35. The other end of the second connecting pipe 31 is fixedly connected to a second oil outlet pipe 7. An annular groove 33 is formed on the outer surface of the second connecting pipe 31. Multiple circular grooves 39 are formed on the inner surface of the annular groove 33. Ball bearings 38 are arranged on the inner surfaces of the multiple circular grooves 39. The outer surfaces of the multiple ball bearings 38 respectively penetrate through the multiple circular grooves 39 and extend into the second connecting pipe 31. A clamping groove 34 for cooperating with the multiple ball bearings 38 is formed on the outer surface of the first connecting pipe 35. The design of the ball bearings 38 and the clamping groove 34 plays a role in positioning and auxiliary fixing when the first connecting pipe 35 and the second connecting pipe 31 are connected, reducing the friction between the connecting pipes, making the connection process smoother, enhancing the reliability of the connection at the same time, reducing the risk of failures such as oil leakage caused by loose connection, and improving the safety and stability of the braking system.

[0031] Furthermore, a return spring 372 is wound around the outer surface of the second connecting pipe 31. One end of the return spring 372 is fixedly connected to one inner wall of the annular groove 33. A clamping pipe 37 is slidably sleeved on the outer surface of the second connecting pipe 31. A fixing ring 371 is fixedly connected to the inner surface of the clamping pipe 37. The other end of the return spring 372 is fixedly connected to the other end of the return spring 372. The clamping pipe 37 and the fixing ring 371 further limit the movement range of the second connecting pipe 31, and cooperate with the return spring 372 to improve the stability and reliability of the connection structure, ensuring that the brake oil circuit always remains unobstructed.

[0032] As Figures 1 to 5 shown in the figure, a sealing ring 32 is fixedly connected to one end of the first oil outlet pipe 4. The inner surface of the sealing ring 32 is sleeved on the outer surface of the first connecting pipe 35, and one end of the sealing ring 32 is in contact with the second connecting pipe 31. The cooperation between the guide block 361 and the guide groove 36 provides a precise guiding function for the sliding of the clamping pipe 37 on the second connecting pipe 31, making the movement of the clamping pipe 37 smoother and more orderly.

[0033] It should be noted that two guide blocks 361 are fixedly connected to the inner surface of the clamping pipe 37. A guide groove 36 for cooperating with the two guide blocks 361 is formed on the outer surface of the second connecting pipe 31. The presence of the sealing ring 32 effectively enhances the sealing performance between the first oil outlet pipe 4, the first connecting pipe 35 and the second connecting pipe 31, preventing brake oil leakage.

[0034] Among them, structures such as motors are prior arts and will not be elaborated here; at the same time, the present utility model also includes a power source, a controller, a switch, etc., which are not the main technical points of this patent and will not be elaborated here. The wiring diagram of the motor in the present utility model belongs to the common knowledge in the art, and its working principle is already a well-known technology. Its model is selected according to actual use, so the control method and wiring layout of the motor will not be explained in detail.

[0035] Working principle and process: When the motorcycle braking system is started, the connecting shaft 6 pushes the piston 24 into the brake pump housing 1 under the action of the transmission mechanism. The movement of the piston 24 will increase the pressure in the inner cavity of the brake pump housing 1. Under the action of the pressure, the brake fluid enters the brake pump housing 1 from the inlet pipe 5, is squeezed and flows to the first outlet pipe 4, and then flows to the braking component through the second outlet pipe 7, thus realizing braking. When it is necessary to disassemble the first outlet pipe 4 and the second outlet pipe 7, first hold the clamping pipe 37 and pull it outwards. The fixing ring 371 in the clamping pipe 37 compresses the return spring 372, so that the ball 38 on the second connecting pipe 31 disengages from the clamping groove 34 of the first connecting pipe 35. At this time, the second connecting pipe 31 can be pulled out from the first connecting pipe 35, and the connection between the first outlet pipe 4 and the second outlet pipe 7 can be disconnected. Then, the old components can be easily removed and new components can be installed without large-scale disassembly of the entire brake pump system. During the operation of the brake pump, heat will be generated due to reasons such as friction. The heat is conducted from the brake pump housing 1 to the heat sink 22. The cooling grooves 21 of the heat sink 22 increase the contact area with the air and the air flow efficiency, so that the heat is quickly dissipated into the surrounding air, thus effectively reducing the working temperature of the brake pump and preventing the performance of the brake fluid from decreasing or the brake pump components from being damaged due to too high temperature, and ensuring the stable and reliable operation of the braking system.

[0036] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device.

[0037] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
