Abstract
Description
Technical Field
[0001] The utility model relates to a brake pump. Background Art
[0002] Most existing motorcycles use hydraulic brakes. The principle of hydraulic braking is that when the brake handle is manually activated, it compresses the piston push rod, driving the piston in the upper pump. This pushes hydraulic oil from the hydraulic oil tank through the oil circuit, driving the piston in the lower brake pump, which in turn drives the brake pads to grip the brake disc, achieving braking. If the seal between the oil cup and oil cup cover of the upper brake pump is not good, the hydraulic oil in the oil cup can leak through the gap between the two cups if the motorcycle rolls over or experiences significant shaking, affecting the subsequent use of the upper brake pump.
[0003] Existing brake pumps with good oil cup sealing effects, such as the motorcycle brake upper pump with patent number CN221091119U, include a brake upper pump body, one side of the brake upper pump body is fixedly connected to an oil cup structure, the oil cup structure includes a cover body, an oil storage box, a sealing ring and a sealing block, one side of the cover body is provided with a mounting hole, the mounting holes are fixed in two and are evenly distributed, a first locking bolt is fixedly installed in the mounting hole, the cover body is fixedly installed with the oil storage box through the first locking bolt, a sealing ring is fixedly installed on the outer surface of the oil storage box, a limit block is provided on the inner surface of the oil storage box, the limit blocks are fixed in four and are evenly distributed, and the sealing block is mounted on the upper end of the limit block.
[0004] This embodiment can prevent the hydraulic oil from leaking out from the gap between the cover and the oil storage box, thereby improving the sealing performance of the oil cup structure. However, it has the following drawbacks:
[0005] 1. There will be impurities in the oil, and the precipitation will block the oil cup and the pump body pipeline;
[0006] 2. The pump body is installed on the motorcycle through the mounting block and the second locking bolt. There is a lack of supporting structure in the connection hole where the bolt is placed, and the bolt will tilt or fall directly. Summary of the Invention

[0055] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.
[0056] Example 1:
[0057] like Figure 1 、 Figure 2 As shown, an embodiment of the present application provides a brake pump, including a main pump body 1, a brake handle 2, an oil storage box 3 and a cover body 4, and also includes: a bracket 5, which is installed between the oil storage box 3 and the cover body 4; and a filter unit 6, which is detachably installed on the bracket 5.
[0058] Furthermore, the filter unit 6 includes a filter box 601, which is installed at the lower end of the bracket 5 by fasteners; a filter screen 602, which is arranged at the bottom end of the filter box 601; and an oil inlet 603, which is arranged on the bracket 5 and downwardly connected to the filter box 601; wherein the filter box 601 is located in the inner cavity of the oil storage box 3.
[0059] In this embodiment of the present application, due to the adoption of the above-mentioned structure, the oil is added to the oil storage box 3 from the oil inlet 603, and the oil first flows from the bracket 5 into the filter box 601. The filter mesh 602 at the lower end of the filter box 601 filters the impurities in the oil, so that the oil and the impurities are separated to avoid clogging the pipeline between the oil and the main pump body 1. The filter box 601 is installed on the bracket 5 by fasteners (for example: screws, bolts, pins, etc.). When impurities need to be cleaned, the cover body 4, the bracket 5 and the filter box 601 can be removed in turn.
[0060] Example 2:
[0061] like Figure 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiment, it also includes: a mounting groove 7, which is arranged at the lower end of the edge side of the bracket 5; and an annular groove 8, which is arranged at the upper end of the edge side of the bracket 5; wherein the mounting groove 7 abuts against the oil storage box 3.
[0062] Furthermore, it also includes a first sealing ring 9, which is arranged in the installation groove 7; and a second sealing ring 10, which is arranged in the annular groove 8.
[0063] Furthermore, it also includes a bending portion 11, which is fixedly connected to the end of the cover body 4; an extension portion 12, which is fixedly connected to the end of the bending portion 11; wherein the bending portion 11 extends inwardly and the inner wall of the extension portion 12 is in contact with the outer wall of the oil storage box 3.
[0064] In this embodiment of the present application, due to the adoption of the above-mentioned structure, in order to improve the sealing between the oil storage box 3 and the cover body 4, a bracket 5 is connected between the oil storage box 3 and the cover body 4, and the mounting groove 7 at the lower end of the bracket 5 near the edge abuts against the upper end of the oil storage box 3, and an annular groove 8 is provided at the upper end of the bracket 5 near the edge. Through the setting of the mounting groove 7 and the annular groove 8, the edge of the bracket 5 is H-shaped, and the groove of the mounting groove 7 fits with the inner and outer walls of the oil storage box 3, thereby ensuring the sealing of the connection between the oil storage box 3 and the bracket 5, and then a first sealing ring 9 is installed in the mounting groove 7 and a second sealing ring 10 is installed in the annular groove 8, which can achieve a double sealing effect. Since the bracket 5 is installed on the oil storage box 3, there will be a gap between the cover body 4 and the oil storage box 3. Therefore, a bending portion 11 is required to be provided at the end of the cover body 4. The bending portion 11 extends downward and obliquely toward the side of the oil storage box 3. An extension portion 12 is extended vertically downward at the end of the extension portion 12. The inner wall of the extension portion 12 fits with the outer wall of the oil storage box 3 to ensure the sealing of the cover body 4 and the oil storage box 3.
[0065] Example 3:
[0066] like Figure 1 、 Figure 3-5As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes: a main semicircular plate 13, which is fixedly connected to the main pump body 1; a secondary semicircular plate 14, which is detachably mounted on the main semicircular plate 13; a first ear block 15, which is arranged on the outer wall of the main semicircular plate 13; a second ear block 16, which is arranged on the outer wall of the secondary semicircular plate 14; and a connecting bolt 17, which is threadedly connected between the first ear block 15 and the second ear block 16.
[0067] Furthermore, it also includes a support groove 18, which is arranged at the lower end of the connecting groove of the second ear block 16; a movable block 19, which is movably installed in the support groove 18; a spring 20, which is arranged in the support groove 18, and its two ends are fixedly connected between the bottom surface of the movable block 19 and the bottom surface of the support groove 18; a magnetic strip 21, which is fixedly connected to the upper end of the movable block 19, and its head end is inserted into the connecting groove of the second ear block 16.

[0069] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the main pump body 1 needs to be installed on the motorcycle, the main semicircular plate 13 and the secondary semicircular plate 14 are wrapped around the mounting bracket of the motorcycle, the connecting holes and connecting grooves of the first ear block 15 and the second ear block 16 are aligned, and the connecting bolt 17 is passed through the connecting hole of the first ear block 15 and screwed into the connecting groove of the first ear block 15. During the screwing process of the connecting bolt 17, the lower end of the connecting bolt 17 contacts the magnetic strip 21, and the magnetic strip 21 pushes the movable block 19 to move toward the inside of the support groove 18. At the same time, the movable block 19 moves downward, the spring 20 shortens, and the magnetic strip 21 attracts the connecting bolt 17, thereby fixing the connecting bolt 17. When the connecting bolt 17 is installed on the first ear block 15, it is necessary to align the clamping blocks 24 on both sides of the connecting bolt 17 with the clamping grooves 23 corresponding to the limit blocks 22. After the connecting bolt 17 is installed, the limit blocks 22 can play a limiting role and prevent the connecting bolt 17 from being misaligned.
