Description

Technical Field

[0001] This utility model relates to the field of automotive parts technology, and in particular to a valve body connection structure for ABS systems that is compatible with multiple vehicle models. Background Technology

[0002] The ABS system valve body is the core hydraulic control unit of the automotive anti-lock braking system. It integrates multiple solenoid valves precisely controlled by the ECU. Through high-speed "pressure build-up-pressure holding-pressure release-pressure rebuild" cycle, it dynamically controls the brake fluid pressure of each wheel cylinder, thereby preventing the wheels from locking up during emergency braking and ensuring the vehicle's steering ability and driving stability.

[0003] When installing an ABS system valve body, it needs to be connected and fixed to the vehicle body via a connecting structure to ensure stability during use. Most existing ABS system valve body connecting structures are fixed. However, due to the variety of vehicle models on the market, the fixed connecting structure makes it difficult for the valve body to be adapted to different vehicle models for installation. During installation, the pre-drilled holes on the vehicle body and the valve body mounting holes must be strictly aligned. Even a slight deviation requires re-grinding or drilling for adjustment, which increases the difficulty of installing the ABS system valve body, reduces installation efficiency, and consequently reduces the ease of use of the ABS system valve body.

[0004] Therefore, this application provides an ABS system valve body connection structure that is adaptable to multiple vehicle models to meet the requirements. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology, and to propose an ABS system valve body connection structure that is compatible with multiple vehicle models.

[0006] The technical problem to be solved by this utility model is to provide a valve body connection structure for ABS systems that is compatible with multiple vehicle models in order to solve the existing problems.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an ABS system valve body connection structure adaptable to multiple vehicle models, including an ABS valve body and a valve body adapter connection seat, wherein the ABS valve body is detachably connected to the surface of the valve body adapter connection seat, the valve body adapter connection seat includes a circular base and an annular array of waist-shaped adjustment holes opened on the surface of the circular base, three sets of connecting ears are fixedly connected to the outer wall of the circular base, and the three sets of connecting ears are symmetrically distributed on the outer wall of the circular base, and a buffer shock absorption component is fixedly nested in the inner cavity of the connecting ear, and an adjustable connecting component that can realize the adjustment of the connection position with the vehicle frame can be detachably connected to the lower surface of the buffer shock absorption component.

[0008] Preferably, the adjustable connection assembly includes a connecting frame, an elongated limiting groove, an elongated adjusting groove, a fastening bolt, a fastening nut, a connecting sleeve, and a sleeve hole. The connecting frame is disposed on the lower surface of the corresponding buffer and shock-absorbing assembly. The surface of the connecting frame has an elongated limiting groove. The inner cavity of the elongated limiting groove has an elongated adjusting groove coaxially. A fastening bolt is fitted on one side of the elongated adjusting groove, and the end of the fastening bolt passes through the buffer and shock-absorbing assembly and extends to the other side of the buffer and shock-absorbing assembly. A fastening nut is threaded onto the end surface of the fastening bolt. A sleeve hole is provided on the side of the connecting frame away from the valve body adapter connecting seat. The inner cavity of the sleeve hole is detachably nested with a connecting sleeve.

[0009] Preferably, the connecting bracket surfaces on both sides of the sleeve hole are threaded with fixing bolts, and the connecting sleeve has threaded connecting holes on both sides that are compatible with the fixing bolts.

[0010] Preferably, the buffer and shock absorption assembly includes an outer sleeve, a shock-absorbing rubber layer, and a metal frame. The shock-absorbing rubber layer is interference-fitted to the inner side of the outer sleeve, and the metal frame is fixedly connected to the inner sidewall of the shock-absorbing rubber layer.

[0011] Preferably, the shock-absorbing rubber layer is made of nitrile rubber.

[0012] Preferably, the inner wall of the outer sleeve has a groove, and the outer wall of the shock-absorbing rubber layer has a protrusion.

[0013] Preferably, the inner cavity of each of the annular array of waist-shaped adjustment holes is fixedly fitted with a wear-resistant nylon bushing.

[0014] Preferably, the circular base has an annular sealing groove on the side facing the ABS valve body, and a rubber O-ring is fitted inside the annular sealing groove.

[0015] In the above solution, the ring-shaped array of waist-shaped adjustment holes of the valve body adapter connector can be used to adjust the installation position of the ABS valve body and the connector according to the requirements. It can adapt to the installation hole spacing requirements of valve bodies of different vehicle models within a certain range. At the same time, the long strip adjustment groove of the adjustable connection component allows the distance between the connecting frame and the vehicle frame to be adjusted along the axis of the adjustment groove when the circular base is connected to the vehicle frame through the connecting frame. Furthermore, the connecting sleeve fixed by the fixing bolt can be replaced with different specifications of connecting sleeves to adapt to the installation positions of different hole diameters of the vehicle frame. This allows it to adapt to the frame layout of different passenger cars, commercial vehicles and other vehicle models within a certain range during installation, expanding the range of ABS valve body installation, improving installation convenience, effectively improving practical effect, and reducing R&D and inventory costs. In the above solution, by using a grooved outer sleeve and an interference fit with the damping rubber layer, and forming a connection structure between the circular base and the connecting frame with the inner metal skeleton, when the vibration generated by the car is transmitted to the ABS valve body through the connecting frame, the damping rubber layer made of nitrile rubber converts the mechanical energy of the vibration into the internal energy of the rubber molecules through the deformation process, thereby absorbing most of the vibration energy and preventing the vibration from being directly transmitted to the valve body adapter connecting seat and the ABS valve body. This prevents the valve body and the connecting structure from loosening due to vibration, improves the stability of the ABS valve body, and the annular sealing groove of the circular base and the rubber O-ring form a reliable seal to further prevent the ABS valve body from loosening, effectively improving the stability of the ABS valve body during use, and thus improving the safety of vehicle use.

[0022] Please see Figure 1 - Figure 4 An ABS system valve body connection structure adaptable to multiple vehicle models includes an ABS valve body 1 and a valve body adapter connector 2. The ABS valve body 1 is detachably connected to the surface of the valve body adapter connector 2. The valve body adapter connector 2 includes a circular base 201 and an annular array of waist-shaped adjustment holes 202 on the surface of the circular base 201. Three sets of connecting ears 3 are fixedly connected to the outer wall of the circular base 201, and the three sets of connecting ears 3 are symmetrically distributed on the outer wall of the circular base 201. A buffer and shock absorption component 4 is fixedly nested in the inner cavity of the connecting ears 3. The lower surface of the buffer and shock absorption component 4... All components are detachably connected to an adjustable connection assembly 5 that allows for adjustment of the connection position with the vehicle frame. Through the position adjustment function of the ABS valve body 1 and the valve body adapter connection seat 2, the circular base 201 and the annular array of waist-shaped adjustment holes 202, combined with the buffer and shock absorption components 4 embedded in the three sets of symmetrical connection ears 3 and the adjustable connection assembly 5 below, it can adapt to the mounting hole spacing of the ABS valve body 1 and the connection position with the vehicle frame of different models within a certain range. It can also absorb vibration through the buffer and shock absorption components 4, effectively improving the adaptability, stability and convenience of the ABS system valve body connection.

[0023] Please see Figure 2 and Figure 3The adjustable connecting assembly 5 includes a connecting frame 501, an elongated limiting groove 502, an elongated adjusting groove 503, a fastening bolt 504, a fastening nut 505, a connecting sleeve 506, and a sleeve hole 507. The connecting frame 501 is located on the lower surface of the corresponding buffer and shock-absorbing assembly. The elongated limiting groove 502 is formed on the surface of the connecting frame 501. The elongated adjusting groove 503 is coaxially formed in the inner cavity of the elongated limiting groove 502. A fastening bolt 504 is fitted on one side of the elongated adjusting groove 503, and the end of the fastening bolt 504 passes through the buffer and shock-absorbing assembly 4 and extends to the other side of the buffer and shock-absorbing assembly 4. The surface of the end of the fastening bolt 504 is threaded. A fastening nut 505 is attached. A sleeve hole 507 is provided on the side of the connecting frame 501 away from the valve body and the adapter connecting seat 2. A connecting sleeve 506 is detachably nested inside the sleeve hole 507. Through the cooperation of the elongated limiting groove 502 on the surface of the connecting frame 501 and the coaxial elongated adjusting groove 503, the fastening bolt 504 can flexibly adjust the relative position of the connecting frame 501 and the buffer shock absorption component 4 along the adjusting groove to adapt to the installation deviation of different vehicle models. At the same time, the detachably nested connecting sleeve 506 in the sleeve hole 507 on one side of the connecting frame 501 can be flexibly replaced with the corresponding specification according to the mounting hole diameter of the vehicle frame, reducing the installation difficulty and improving the installation convenience and efficiency.

[0024] Please see Figure 4 The connecting brackets 501 on both sides of the sleeve hole 507 are threaded with fixing bolts 509. The connecting sleeve 506 has threaded connecting holes 508 on both sides that are compatible with the fixing bolts 509. The connecting sleeve 506 and the connecting bracket 501 are firmly fixed by tightening the bolts, which prevents the connecting sleeve 506 from loosening due to vehicle vibration. The connecting sleeve 506 with different hole diameters can be quickly replaced by removing the fixing bolts 509. It can flexibly adapt to different mounting hole sizes on the frame without replacing the entire connecting bracket 501. This effectively improves the compatibility with the frame of multiple vehicle models and reduces the limitations of use.

[0025] Please see Figure 4The shock-absorbing assembly 4 includes an outer sleeve 401, a shock-absorbing rubber layer 402, and a metal frame 403. The shock-absorbing rubber layer 402 is interference-fitted to the inner side of the outer sleeve 401. The metal frame 403 is fixedly connected to the inner wall of the shock-absorbing rubber layer 402. The shock-absorbing rubber layer 402 is made of nitrile rubber. A groove 405 is provided on the inner wall of the outer sleeve 401, and a protrusion 404 is provided on the outer wall of the shock-absorbing rubber layer 402. The shock-absorbing rubber layer 402 is connected to the inner groove 405 of the outer sleeve 401 and the outer protrusion 404 of the shock-absorbing rubber layer 402. The current locking mechanism, combined with the interference fit between the two parts and the support of the inner metal frame 403, not only restricts the radial movement of the shock-absorbing rubber layer 402 through the engagement of the protrusion 404 and the groove 405, ensuring structural stability during vibration transmission, but also increases the contact area between the rubber layer and the outer sleeve 401, improving the vibration energy absorption efficiency. Furthermore, the metal frame 403 can prevent excessive deformation of the rubber layer. The three elements work together to ensure the operational stability of the ABS valve body 1 under complex vibration conditions, effectively extending the service life of the valve body.

[0026] Please see Figure 2 The inner cavity of the annular array of waist-shaped adjustment holes 202 is fixedly fitted with wear-resistant nylon bushings 203. The circular base 201 has an annular sealing groove 204 on the side facing the ABS valve body 1, and a rubber O-ring 205 is fitted inside the annular sealing groove 204. The wear-resistant nylon bushings 203 can reduce the direct wear between the high-strength alloy bolts and the hole wall, and extend the service life of the adjustment holes. The annular sealing groove 204 on the side of the circular base 201 facing the ABS valve body cooperates with the rubber O-ring to form a reliable seal when the valve body and the connecting seat are in contact, effectively preventing hydraulic oil leakage and preventing loosening of both, thus ensuring stability during use.

[0027] Working principle: First, the ABS valve body 1 is placed against the sealing surface of the circular base 201 facing the valve body, so that the valve body mounting hole is aligned with the annular array of waist-shaped adjustment holes 202 on the surface of the circular base 201. The valve body is moved laterally along the waist-shaped adjustment holes to the appropriate hole spacing position. When the installation angle needs to be adjusted, the valve body can be rotated around the center of the circular base 201 to the target angle. After inserting the high-strength alloy bolt, it is tightened. At this time, the fluororubber O-ring in the annular sealing groove 204 of the circular base 201 is compressed to form a reliable hydraulic seal. Next, the outer sleeve 401 with groove 405 and the shock-absorbing rubber layer 402 with protrusion 404 are interference-fitted. The inner metal frame 403 is fixedly embedded in the inner cavity of the connecting ear 3 on the outer wall of the circular base 201. Then, the connecting frame 501 of the adjustable connecting assembly 5 is attached to the lower surface of the buffer unit, so that the long strip adjustment groove 503 of the connecting frame 501 is aligned with the mounting hole of the buffer unit. According to the height difference of the frame, the connecting frame 501 is moved to the target position along the axial direction of the adjustment groove. The fastening bolt 504 is inserted through the long strip adjustment groove 503 and the buffer unit. The fastening nut 505 is put on and tightened according to the corresponding torque. Next, the connecting bracket 501 is fixed to the frame. According to the mounting hole diameter of the frame, the matching connecting sleeve 506 is selected and nested into the sleeve hole 507 of the connecting bracket 501. The connecting sleeve 506 is tightened and fixed by the threaded connecting holes 508 on both sides of the connecting sleeve 506 and the fixing bolts 509 on the surface of the connecting bracket 501. Then, the bolts are passed through the mounting holes of the horizontal section of the connecting bracket 501 and the reserved holes of the frame to complete the overall fixation. During use, when the car vibrates, the nitrile rubber damping layer of the buffer unit absorbs vibration energy through deformation, preventing the vibration from being transmitted to the ABS valve body. At the same time, the fluororubber O-rings continuously ensure the seal, ensuring the stable operation of the valve body and effectively improving the safety of car use.
