Description

Technical Field

[0001] The invention relates to a brake pump which can be quickly disassembled and assembled. Background Art

[0002] The brake pump, also known as the brake caliper, is a key component in the automobile brake system. It is mainly composed of a caliper body, a piston, a brake pad, a brake oil pipe, etc. The caliper body is the main frame of the brake pump. The piston is installed in the caliper body. The brake pad is located between the caliper body and the brake disc. The brake oil pipe is responsible for transporting the brake oil from the master brake cylinder to the brake pump. In the prior art, the brake pump is usually installed and fixed by screws, but the screw installation has the following disadvantages:

[0003] When installing the screws, the tightening torque needs to be strictly controlled. If the torque is too small, the screws may not provide sufficient tightening force, causing the brake pump to loosen during use; if the torque is too large, it may damage the screws, the mounting holes of the brake pump or related parts, and may even cause the screws to slip or break, affecting the reliability of the installation and the normal use of the brake pump;

[0004] Although screws can provide a good tightening effect during installation, they may gradually loosen during long-term driving of the vehicle due to factors such as vibration, thermal expansion and contraction. Once the screws are loose, the installation stability of the brake pump will be affected, which may cause brake failure. Regular inspection and tightening of the screws are required, increasing the maintenance workload. Summary of the invention

[0058] The quick-disassembly and assembly brake pump provided in the embodiment of the present application will be described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0059] Embodiment 1:

[0060] like Figures 1 to 3 As shown, the embodiment of the present application provides a brake lower pump that can be quickly disassembled and assembled, including a lower pump body 1 and a mounting bracket 2, and also includes a pair of mounting structures 3, which are respectively arranged at both ends of the mounting bracket 2, and each includes a sleeve 31, which is fixed on the mounting bracket 2, and the inner cavity passes through from top to bottom; a rotating connecting piece 32, which is connected to the sleeve 31 by a thread, and can be fixed to the sleeve 31 by a limiting piece 33; a pair of telescopic blocks 34, which are movably mounted at the bottom of the rotating connecting piece 32, and the telescopic block is controlled by a transmission mechanism 35 that cooperates with the inner cavity of the sleeve 31.

[0061] Furthermore, the rotating connecting member 32 includes a lower section 321, which is slidably installed in the inner cavity of the sleeve 31, and the middle section 322 is rotatably installed on the top; a mounting groove 323, which is arranged on the top of the middle section 322, and the upper section 324 is movably installed through a hinge shaft; a hand wheel 325, which is fixedly arranged on the top of the upper section 324, and a notch 326 for plugging with the limiting member 33 is provided on the opposite side; a limiting member 4, which is used to fix the upper section 324 and the middle section 322, and the outer peripheral walls of the upper section 324 and the middle section 322 are provided with threads, and a pair of telescopic blocks 34 are movably installed on the lower section 321.

[0062] In this embodiment of the present application, due to the adoption of the above-mentioned structure, during installation, the mounting structure 3 on the mounting bracket 2 is aligned with the preset hole on the vehicle mounting part, and then the upper section 324 is turned to rotate around the hinge shaft to be coaxial with the middle section 322 and the lower section 321, and then the hand wheel 325 is turned to make the upper section 324 and the middle section 322 and the sleeve 31 transmit through the thread, and the upper section 324, the middle section 322 and the lower section 321 descend in the sleeve 31, and the lower section 321 passes through the sleeve 31 and extends into the preset hole on the vehicle mounting part, and the lower section 321 continues to extend into the preset hole on the vehicle mounting part, and at the same time the transmission mechanism 35 is actuated, The telescopic blocks 34 are extended, and the outer ends of the telescopic blocks 34 are inclined. The lower ends of the holes preset on the vehicle mounting parts are conical surfaces, so that the telescopic blocks 34 are smoothly matched with the inner peripheral walls of the holes preset on the vehicle mounting parts during the process of descending and extending, until the bottom surface of the hand wheel 325 abuts against the top surface of the sleeve 31, and the limiting member 33 fixes the sleeve 31 so that it can no longer rotate relative to the sleeve 31, and the extension degree of each telescopic block 34 is also fixed. At this time, the distance between the outer ends of a pair of telescopic blocks 34 is at the maximum extent, which is greater than the width of the preset holes on the vehicle mounting parts close to the end of the mounting bracket 2. At this time, the mounting bracket 2 is fixed to the vehicle mounting parts;

[0063] During disassembly, the hand wheel 325 is reversed, and the upper section 324, the middle section 322, the lower section 321 and the pair of telescopic blocks 34 are all moved in a direction away from the vehicle mounting part. At the same time, the transmission mechanism 35 is actuated to move the pair of telescopic blocks 34 closer to each other. During this process, the inclined outer ends of the pair of telescopic blocks 34 are kept in cooperation with the conical surface of the lower section 321 of the preset hole on the vehicle mounting part. When the distance between the outer ends of the pair of telescopic blocks 34 is smaller than the minimum diameter of the top of the conical surface of the preset hole on the vehicle mounting part, the mounting bracket 2 can be directly moved in a direction away from the vehicle mounting part to complete the disassembly action.

[0064] Embodiment 2:

[0065] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the limit member 4 includes a transverse groove 41, which is arranged in the middle of the middle section 322; a connecting hole 42, which is arranged at the top of the middle section 322 and connected to the middle of the transverse groove 41; a pair of engaging arc grooves 43, which are symmetrically arranged on the opposite inner walls of the mounting groove 323; a lifting engaging member 44, which is floatingly installed in the connecting hole 42 and the transverse groove 41, fixedly connected to the hand wheel 325, and the two ends of the bottom are used to engage with the pair of engaging arc grooves 43.

[0066] Furthermore, the engaging arc groove 43 includes an arc groove 431, which is arranged on the inner wall of the mounting groove 323; a pair of engaging grooves 432 are respectively arranged at both ends of the arc groove 431 and extend toward the rotating shaft. The arc groove 431 is concentric with the rotating shaft, and its central angle is ninety degrees.

[0067] Furthermore, the lifting and lowering engaging member 44 includes a cover ring 441, which is fixedly arranged at the top of the middle section 322, and a vertical rod 442 is movably installed in the inner ring; a cross rod 443, which is lifted and lowered in the horizontal groove 41, and the middle part is fixedly connected to the lower end of the vertical rod 442, and both ends extend out of the horizontal groove 41; a pressure spring 444, which is sleeved on the outside of the vertical rod 442, and the two ends are respectively abutted against the cover ring 441 and the cross rod 443.

[0068] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the upper section 324 is located outside the sleeve 31, the hand wheel 325 is lifted outward, the vertical rod 442 and the cross bar 443 rise at the same time, the pressure spring 444 is compressed and shortened, and the two ends of the cross bar 443 enter the corresponding arc groove 431 from the corresponding slot 432, and then the upper section 324 is pulled to rotate around the hinge shaft to a vertical position with the middle section 322, and the two ends of the cross bar 443 slide toward the other end of the corresponding arc groove 431, and then the hand wheel 325 is released, and the pressure spring 444 releases its elastic potential energy, pushing the hand wheel 325, the vertical rod 442 and the cross bar 44 3 is lowered, so that the two ends of the cross bar 443 are inserted into the corresponding slots 432 at the other end of the arc groove 431. When the lower section 321 needs to be inserted into the preset hole on the vehicle mounting part, the hand wheel 325 is pulled outwardly from the upper section 324, and the two ends of the cross bar 443 are separated from the corresponding slots 432. Then, the upper section 324 is pulled until it is coaxial with the middle section 322, and then the hand wheel 325 is released, and the two ends of the cross bar 443 are inserted into the corresponding slots 432 at this time. Then, the hand wheel 325 is turned to rotate the upper section 324, the middle section 322 and the lower section 321, so that the lower section 321 is inserted into the preset hole on the vehicle mounting part.

[0069] Embodiment 3:

[0070] like Figures 2 to 3 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the transmission mechanism 35 includes a lower groove 351, which passes through the lower part of the lower section 321 on the left and right; an upper groove 352, which passes through the upper part of the lower section 321 on the left and right, and is connected to the lower groove 351 through a central groove 353; a central slide rod 354, which is slidably installed in the central groove 353, with a return spring on the top, a connecting rod extending into the lower groove 351 fixed at the bottom, and a sliding rod 355 in the middle; a pair of inner vertical grooves 356, symmetrically arranged at the bottom of the inner cavity wall of the sleeve 31, respectively slidably cooperate with the two ends of the sliding rod 355; a pair of swing arms 357, one end of which is respectively hinged to the inner end wall of each telescopic block 34, and the other end is simultaneously hinged to the lower end of the connecting rod, and a pair of telescopic blocks 34 are respectively slidably installed at both ends of the lower groove 351.

[0071] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when the lower section 321 descends in the inner cavity of the sleeve 31, the sliding rod 355 descends in the pair of inner vertical grooves 356 until the pair of telescopic blocks 34 enter the lower half of the conical surface of the preset hole on the vehicle mounting part, and the two ends of the sliding rod 355 contact the bottom surface of the pair of inner vertical grooves 356, so that the position of the central sliding rod 354 is fixed, and the lower section 321 and the pair of telescopic sliders continue to descend, the return spring is compressed and shortened, and the pair of swing arms 357 swing, and the two ends are separated from each other, pushing the corresponding telescopic slider to extend out of the lower groove 351. During the descent process, the outer end of each telescopic slider continues to extend and keeps in contact with the conical surface of the lower half of the preset hole on the vehicle mounting part;

[0072] When the lower section 321 rises in the inner cavity of the sleeve 31, the return spring releases its elastic potential energy, pushing the central slide bar 354 down in the central groove 353, and a pair of swing arms 357 swing, with both ends approaching each other, pulling a pair of telescopic slide blocks to retract into the lower groove 351 and rise at the same time. The effect presented is that during the process of a pair of telescopic blocks 34 rising in the conical surface of the lower half of the preset hole on the vehicle mounting part, the outer ends remain in contact with the inner circumferential wall of the conical surface, and after the pair of telescopic blocks 34 are completely separated from the lower half of the preset hole on the vehicle mounting part, the pair of telescopic blocks 34 also completely enter the lower groove 351.

[0075] Furthermore, the limiting member 33 also includes a pair of limiting vertical grooves 336, which are respectively arranged at the inner ends of each outer vertical groove 331; a pair of limiting bolts 337 are symmetrically arranged on the ring sleeve 335, and after passing through the corresponding floating blocks 332, they are slidably matched with the corresponding limiting vertical grooves 336.

[0076] Furthermore, the limiting member 33 further includes a semicircular receiving groove 338 , which is disposed on the same side of the sleeve 31 and the ring sleeve 335 , and is used to receive the upper section 324 .

[0077] The cam 334 is pressed against the top of the handle 325 and the bottom of the handle 325 is pressed against the top of the handle 325, and the cam 334 is pressed against the top of the handle 325.

[0078] When the upper section 321 is turned over until its axis is perpendicular to the axis of the middle section 322 , the outer wall of the upper end 321 engages with the semicircular receiving groove 338 , so that the middle section 322 can no longer rotate and prevent it from escaping from the sleeve 31 .

[0079] It should be noted that, in this article, the terms "comprise", "include" or any other variant thereof are intended to cover non-exclusive inclusion, so that the process, method, article or device including a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
