Description

Technical Field

[0001] The invention relates to the field of disc brake pumps, and in particular to an electric vehicle disc brake pump structure which is easy to install and disassemble. Background Art

[0002] In the electric vehicle industry, disc brake pumps are key brake components. The ease of installation and disassembly as well as the sealing during use have a significant impact on vehicle performance and user experience. At present, the installation method of the pump part of the traditional electric vehicle disc brake pump is relatively cumbersome, and the screws need to be over-tightened to ensure a stable connection. This not only increases the difficulty of installation, but also makes disassembly extremely difficult when maintenance or replacement of parts is required in the future, which consumes a lot of time and manpower; At the same time, during the adjustment of the brake system, it is usually necessary to remove the oil seal cover. If the oil box body is not in a exactly horizontal state at this time, the oil will easily spill after the oil seal is removed, which will not only increase the cost of use, but may also contaminate other parts of the vehicle, affecting the overall performance and appearance of the vehicle, and even pose a safety hazard. Therefore, how to solve the above problems needs to be considered. Summary of the invention

[0003] The purpose of the present invention is to solve the shortcomings existing in the prior art, and to propose an electric vehicle disc brake pump structure which is easy to install and disassemble. This scheme adopts an installation method of positioning and screw connection. When in use, the screws do not need to be tightened too much, which facilitates disassembly and installation. In addition, the oil box part is extended to avoid oil leakage to the greatest extent when adjusting the brake system, that is, when the oil seal cover is removed.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A disc brake pump structure for an electric vehicle which is easy to install and disassemble, comprises a connecting seat, a holding handle is installed on the left side of the connecting seat, an oil box body is installed on the right side of the connecting seat, and a connecting head is arranged at the upper end of the connecting seat; an oil box sealing mechanism, the oil box sealing mechanism comprises a sealing cover arranged at the upper end of the oil box body, and the sealing cover is installed on the oil box body by a plurality of first screws; a limiting mechanism, the limiting mechanism comprises a second limiting block fixedly connected to the front side of the connecting seat, a first limiting block is arranged on the front side of the second limiting block, the opposite surfaces of the second limiting block and the first limiting block are both in arc shape, a rectangular block is fixedly connected to the rear side of the first limiting block, a rectangular slot is opened on the front side of the second limiting block, and the rear end of the rectangular block extends into the interior of the rectangular slot.

[0005] Preferably, a circular groove is provided at the upper end of the oil box body, a circular sealing plate which can slide up and down is arranged in the circular groove, and the lower end of the circular sealing plate is elastically connected to the inner bottom of the circular groove through a plurality of first springs.

[0006] Preferably, the opposing surfaces of the second limiting block and the first limiting block are both fixedly connected with insert blocks, and the front side of the first limiting block is fixedly connected with a pull ring.

[0007] Preferably, the inner top and inner bottom of the rectangular slot are respectively provided with a first threaded opening and a second threaded opening, the rectangular block is provided with a third threaded opening, and the first threaded opening, the second threaded opening and the third threaded opening are commonly threadedly connected with a second screw.

[0008] Preferably, the upper end of the second limit block is fixedly connected to a vertical plate, the front side of the vertical plate is fixedly connected to a connecting plate, the front side of the connecting plate is provided with a rectangular piston groove, a rectangular piston plate that can slide back and forth is arranged in the rectangular piston groove, and the rear side of the rectangular piston plate is elastically connected to the rear inner wall of the rectangular piston groove through a plurality of third springs.

[0009] Preferably, a blocking plate is fixedly connected to the front side of the rectangular piston plate, the front side of the blocking plate passes through the notch of the rectangular piston groove, and the lower end surface of the blocking plate contacts the upper end surface of the second screw.

[0010] Preferably, the rear space of the rectangular piston groove is connected to the outside through a first one-way port and a second one-way port, the inner diameter of the first one-way port is one-fourth of the inner diameter of the second one-way port, a first one-way valve is installed inside the first one-way port, and a second one-way valve is installed inside the second one-way port.

[0011] Preferably, the first one-way valve flows in a direction that the rectangular piston groove discharges the outside in one direction, and the second one-way valve flows in a direction that the outside enters the rectangular piston groove in one direction.

[0012] Preferably, a cylindrical groove is provided on the front side of the second limit block, and a sliding column is fixedly connected to the rear side of the first limit block. The rear end of the sliding column extends into the cylindrical groove and is slidably connected to the inner wall of the cylindrical groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. Move the first limit block away from the second limit block, align it with the socket and release it. It will be automatically inserted and positioned under the action of the second spring. The operation is simple and no complicated calibration is required. The initial positioning of the connecting seat and the handlebar of the electric vehicle can be quickly achieved, saving installation time.

[0014] 2. When tightening the second screw, there is no need to over-tighten it, which makes subsequent disassembly easy. Before installation, the blocking plate is moved back, and the one-way opening characteristic is used to slow down the reset of the blocking plate, providing sufficient time for installation. The same applies to disassembly, reducing the difficulty of installation and disassembly.

[0015] 3. After the baffle plate is reset, the lower end surface always contacts with the upper end surface of the second screw, effectively preventing the second screw from loosening, ensuring the connection stability. At the same time, since there is no need to over-tighten the second screw, the disassembly difficulty is further reduced.

[0016] 4. After removing the sealing cover for adjusting the brake system, the return-shaped sealing plate moves upward under the action of the first spring, increasing the accommodating space. Even if the structure is tilted, the oil will not pour out, effectively preventing oil leakage and reducing waste and pollution. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Referring to Figures 1-6 , a structure of an electric vehicle disc brake pump that is convenient for installation and disassembly, includes a connecting seat 1, a holding handle 4 is installed on the left side of the connecting seat 1, an oil box body 3 is installed on the right side of the connecting seat 1, and a connecting head 2 is arranged at the upper end of the connecting seat 1; As an embodiment of the present invention, it further includes an oil cartridge sealing mechanism. The oil cartridge sealing mechanism includes a sealing cover 32 arranged at the upper end of the oil cartridge body 3. The sealing cover 32 is installed on the oil cartridge body 3 through a plurality of first screws 31. A rectangular groove 5 is opened at the upper end of the oil cartridge body 3. A slidable rectangular sealing plate 6 is arranged in the rectangular groove 5. The lower end of the rectangular sealing plate 6 is elastically connected to the inner bottom of the rectangular groove 5 through a plurality of first springs 7. At this time, the first springs 7 are in a compressed state. When the braking system needs to be adjusted, after the sealing cover 32 is opened, under the elastic action of the first springs 7, the rectangular sealing plate 6 moves upward, making the accommodating space larger. Even if the overall structure is in a tilted state at a relatively small angle at this time, the oil will not pour out. As an embodiment of the present invention, it further includes a limiting mechanism. The limiting mechanism includes a second limiting block 9 fixedly connected to the front side of the connecting seat 1. A first limiting block 8 is arranged on the front side of the second limiting block 9. The opposite surfaces of the second limiting block 9 and the first limiting block 8 are both arc-shaped. A rectangular block 22 is fixedly connected to the rear side of the first limiting block 8. A rectangular slot 21 is opened on the front side of the second limiting block 9. The rear end of the rectangular block 22 extends into the interior of the rectangular slot 21. First threaded openings 23 and second threaded openings 24 are respectively opened at the inner top and inner bottom of the rectangular slot 21. A third threaded opening 30 is opened on the rectangular block 22. A second screw 25 is commonly threadedly connected to the first threaded opening 23, the second threaded opening 24, and the third threaded opening 30. As an embodiment of the present invention, a vertical plate 12 is fixedly connected to the upper end of the second limiting block 9. A connecting plate 13 is fixedly connected to the front side of the vertical plate 12. A rectangular piston groove 27 is opened on the front side of the connecting plate 13. A slidable rectangular piston plate 28 is arranged in the rectangular piston groove 27. The rear side of the rectangular piston plate 28 is elastically connected to the rear inner wall of the rectangular piston groove 27 through a plurality of third springs 29. A blocking plate 26 is fixedly connected to the front side of the rectangular piston plate 28. By using the blocking of the blocking plate 26, the loosening of the second screw 25 can be avoided. During specific use, there is no need to tighten the second screw 25 too much. The front side of the blocking plate 26 penetrates through the notch of the rectangular piston groove 27. The lower end surface of the blocking plate 26 contacts the upper end surface of the second screw 25. The rear space of the rectangular piston groove 27 is communicated with the outside through a first one-way port 14 and a second one-way port 16. The inner diameter of the first one-way port 14 is one-fourth of the inner diameter of the second one-way port 16. A first one-way valve 15 is installed inside the first one-way port 14. A second one-way valve 17 is installed inside the second one-way port 16. The flow direction of the first one-way valve 15 is unidirectional discharge from the rectangular piston groove 27 to the outside, and the flow direction of the second one-way valve 17 is unidirectional entry from the outside into the rectangular piston groove 27. As an implementation manner of the present invention, insertion blocks 10 are fixedly connected to the opposite surfaces of the second limiting block 9 and the first limiting block 8. Further, there is a socket matching the installation position of the electric vehicle handle, and the insertion block 10 is inserted into the socket to complete positioning. At this time, the operation of screwing the screw can be carried out. A pull ring 11 is fixedly connected to the front side of the first limiting block 8; As an implementation manner of the present invention, a cylindrical groove 18 is opened on the front side of the second limiting block 9. A sliding column 20 is fixedly connected to the rear side of the first limiting block 8. The rear end of the sliding column 20 extends into the cylindrical groove 18 and is slidably connected to the inner wall of the cylindrical groove 18. The rear side of the sliding column 20 is elastically connected to the rear inner wall of the cylindrical groove 18 through a second spring 19.

[0024] In the present invention, the first limiting block 8 and the second limiting block 9 are brought close to the installation position of the electric vehicle handle. The first limiting block 8 is moved away from the second limiting block 9. Then, after the insertion block 10 corresponds to the socket, the first limiting block 8 is released. Under the elastic action of the second spring 19, the first limiting block 8 moves close to the second limiting block 9, and the two insertion blocks 10 are inserted into the two sockets; The first limiting block 8 and the second limiting block 9 are fixedly connected by screwing a second screw 25 into the first threaded port 23, the third threaded port 30, and the second threaded port 24 in sequence, completing the installation of the connecting seat 1 and the electric vehicle handle. When tightening the second screw 25, there is no need to over-tighten, which facilitates subsequent disassembly. Before screwing the second screw 25, the blocking plate 26 can be first moved backward a large distance and then released. After releasing, under the elastic action of the third spring 29, the rectangular piston plate 28 will move forward and drive the blocking plate 26 to move forward. However, due to the small aperture of the first one-way port 14 and the slow gas replenishment speed, the reset speed of the rectangular piston plate 28 is slow, and this time period is sufficient for the work to install the second screw 25 (the same is true for disassembly); When the blocking plate 26 is reset, the lower end surface thereof always contacts the upper end surface of the second screw 25 to prevent the second screw 25 from loosening. Since there is no need to over-tighten the second screw 25, the disassembly is relatively easy; If the brake system needs to be adjusted, the sealing cover 32 is disassembled. After disassembly, under the elastic action of the first spring 7, the return-shaped sealing plate 6 moves upward, increasing the accommodating space. Even if the overall structure is in a small-angle inclined state, the oil will not pour out, avoiding oil leakage.

[0025] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
