Description

Technical Field

[0001] The utility model relates to the technical field of brake pumps, in particular to an integrated brake pump. Background Art

[0002] With the increasing number of daily use, some consumers will buy portable transportation tools such as motorcycles and electric vehicles for the convenience of daily travel. With the increasing demand for motorcycles and electric vehicles, their safety performance is becoming more and more important. Usually, a motorcycle brake system includes a brake handle, a brake lower pump, an oil circuit and a brake upper pump. At present, the brake lower pump is usually composed of a first pump body and a second pump body, that is, the brake lower pump is a split pump body, and the first pump body and the second pump body are connected by bolts and other components. However, the design of the first pump body and the second pump body will result in a gap between the first pump body and the second pump body. During daily use, the gap between the first pump body and the second pump body is affected by external stress impact. It will gradually increase and even cause the first pump body part to loosen relative to the second pump body part, and the split pump body design will cause the pressure resistance of the entire pump body to be weak. During daily use, it is easily affected by the vibration of the vehicle, resulting in bumps and other phenomena at the connection between the first pump body part and the second pump body part, and even the breakage of connecting parts such as bolts. At the same time, the split design affects the production efficiency, that is, the first pump body part and the second pump body part need to be produced separately, and the bolts and other connecting parts also need to be produced separately and then assembled separately, which greatly affects the production efficiency. If the pump body is designed to be an integrated unit, it will make its internal brake cavity and the piston groove in the brake cavity and other structures difficult to process. Utility Model Content

[0003] In view of the shortcomings of the prior art, the utility model provides an integrated brake pump to solve the problem that the prior art lacks an integrated brake pump that is easy to process and has excellent pressure resistance.

[0004] In order to achieve the above-mentioned purpose, the utility model provides an integrated brake pump, including a pump body that is integrally formed by processing, the pump body is provided with a brake cavity for installing external brake components, the pump body is provided with a processing hole for inserting an external processing device to process the brake cavity, the processing hole is connected to the brake cavity, the processing hole is provided with a cover plate for sealing the processing hole after the brake cavity is processed, the cover plate is threadedly matched with the processing hole, and the cover plate is provided with a limit member for preventing the cover plate from separating from the processing hole when the threaded matching between the cover plate and the processing hole fails.

[0005] The benefits of adopting the above technical solution are: in the above technology, the brake pump body is processed and formed into an integral part. Compared with the technology in the prior art that the first pump body part and the second pump body part are produced separately and then connected by connecting parts to form the pump body, this technology does not need to produce the first pump body part and the second pump body part separately, thereby improving production efficiency, and also does not need connecting parts such as bolts, thereby reducing cost expenditure; compared with the technical problems in the prior art that cracks appear between the first pump body part and the second pump body part or the two pump bodies become loose after long-term use or under external stress impact, in the present technology, the entire pump body is integrated to improve the overall compressive strength of the pump body, thereby eliminating safety hazards, thereby improving safety performance and service life; and the pump body is processed to form a brake cavity, and the brake cavity is initially processed and its internal holes are all processed, so a processing hole connected to the brake cavity is processed on the pump body, so that external processing equipment can enter the brake cavity and perform processing on the brake cavity. Processing is carried out, and according to design requirements, piston groove processing, hole processing, grooving processing, internal shape processing of the brake cavity, etc. are carried out inside the brake cavity, thereby improving processing efficiency; after processing is completed, the cover plate is used to close the processing hole through the threaded cooperation between the cover plate and the processing hole, thereby preventing external impurities or foreign matter from entering the brake cavity and corroding the brake components installed in the brake cavity or affecting the operation of the brake components. The setting of the limit member in the above technology is used to limit the cover plate through the limit member when the pump body is used for a long time or the pump body is subjected to high load impact. If the thread cooperation between the cover plate and the processing hole fails, the cover plate can be limited by the limit member to avoid separation of the cover plate and the processing hole, resulting in failure of the sealing of the processing hole, thereby preventing external impurities or foreign matter from entering the brake cavity and corroding the brake components installed in the brake cavity or affecting the operation of the brake components; the setting of the processing hole in the above technology can also facilitate the installation of external brake components, thereby improving disassembly and assembly efficiency.

At the same time, the design of the first step surface and the second step surface avoids horizontal shaking of the cover plate when it is impacted by high external loads, thereby improving the stability of the cover plate in the processing hole; in the above technology, the first limit portion and the cover plate are integrally processed and formed, that is, the first limit portion and the cover plate are the same force-bearing component, and the technical problem of separation or loosening between the first limit portion and the cover plate is avoided, thereby improving the stability of the cover plate in the processing hole.

The plate shakes horizontally when impacted by a high external load, thereby improving the stability of the cover plate in the processing hole; in the above technology, the second limiting portion and the cover plate are integrally processed and formed, that is, the second limiting portion and the cover plate are the same force-bearing component, and the technical problem of separation or loosening between the second limiting portion and the cover plate is avoided, thereby improving the stability of the cover plate in the processing hole; in the above technology, the radial cross-section of the combination of the outer peripheral wall of the second limiting portion, the outer peripheral wall of the first limiting portion and the outer peripheral wall of the cover plate is stepped, thereby forming a stepped limiting surface, thereby improving the stability of the cover plate in the processing hole.

For example, to meet the sealing requirements, a waterproof sealing rubber can be installed in the reserved cavity to improve the sealing strength between the reserved groove and the second limiting part, thereby improving the sealing strength between the processed hole and the brake pump body.
