Description

Technical Field

[0001] This utility model relates to the field of air suspension shock absorber technology, and in particular to an electro-hydraulic air suspension intelligent shock absorber. Background Technology

[0002] An air suspension shock absorber is a type of shock absorber that uses air pressure to adjust the vehicle's suspension system. It consists of components such as an air spring, a hydraulic shock absorber, rubber stops, and a housing. The air spring is fitted onto the housing. Traditionally, the housing component of an air suspension shock absorber is die-cast as a single piece. Therefore, its structure is difficult to adjust according to the actual assembly situation. For example, after the hydraulic shock absorber is installed into the housing, the length of the exposed part of the hydraulic shock absorber is difficult to adjust when installing the air spring. This makes it difficult to quickly assemble the air spring with the hydraulic shock absorber, or after assembling it with the shock absorber, it is difficult to quickly assemble it onto the housing. This situation requires the user to make constant adjustments during the assembly process, which is time-consuming and laborious, reducing the assembly efficiency of the air suspension shock absorber.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0004] This utility model proposes an intelligent shock absorber for electric hydraulic air suspension, which solves the above-mentioned problems existing in the use of the prior art.

[0005] The technical solution of this utility model is implemented as follows: An intelligent shock absorber for electric hydraulic air suspension includes a housing component. One end of the housing component is connected to an adjusting bottom tube, and a fixing plate is embedded in one end of the housing component. A retaining ring is snapped inside the fixing plate. A connecting bolt arranged in a circular array is provided through one side of the fixing plate. The retaining ring is fixedly installed inside the fixing plate by the connecting bolts. A connecting screw arranged in a circular array is provided through one side of the fixing plate. A nut located outside the fixing plate is threaded onto one end of the connecting screw. The fixing plate is fixedly installed on the housing component by the connecting screw. A spring is sleeved on the surface of the connecting screw. The two ends of the spring are respectively fixedly connected to the connecting screw and the inner wall of the housing component.

[0006] The present invention, as described above, is used for an intelligent shock absorber for an electric hydraulic air suspension.

Further, the top and bottom of the inner cavity of the housing are provided with limiting grooves, and the top and bottom of the adjusting bottom tube are fixedly connected with limiting sliders adapted to the limiting grooves.

[0008] The present invention provides an intelligent shock absorber for electric hydraulic air suspension as described above, further comprising: the bottom of the limiting slider is provided with equally spaced slots, and multiple slots are adapted to nuts.

[0009] The present invention, as described above, is used for an intelligent shock absorber for an electric hydraulic air suspension. Further, a hydraulic shock absorber is provided inside the housing and the adjusting base tube. The hydraulic shock absorber includes a shock absorber housing, and a shock absorber push rod is slidably installed inside the shock absorber housing. A piston located in the inner cavity of the shock absorber housing is fixedly installed at one end of the surface of the shock absorber push rod.

[0010] The present invention, as described above, is used for an intelligent shock absorber for an electric hydraulic air suspension.

[0011] The present invention, as described above, is used for an intelligent shock absorber for an electric hydraulic air suspension. Further, one end of the inner side of the housing is provided with a second threaded hole arranged in a circular array, and the second threaded hole is adapted to the connecting screw.

[0012] In summary, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model adopts a flexible adjustable structure design for the shock absorber housing. During installation, the length of the housing can be adjusted to save time and effort when installing the air spring, enabling quick assembly of various components and increasing the installation speed of the shock absorber, thus providing convenience for users.

[0014] 2. This utility model provides convenience for users' installation work by setting a threaded hole and a through hole. The threaded hole is used to insert and install the connecting screw, and the through hole is used to insert and install the connecting bolt.

[0015] 3.

In this way, when the shock absorber push rod slides inside the shock absorber housing, the sealing between the shock absorber push rod and the shock absorber housing can be guaranteed, avoiding air leakage. When the hydraulic shock absorber is working, under the heavy pressure of the vehicle, the shock absorber push rod will slide into the shock absorber housing, and in cooperation with the piston, it will compress the air inside the shock absorber housing. At the same time, in cooperation with the rubber stop, it will also compress the air spring, thereby achieving the purpose of buffering and shock absorption.

[0018] 6. This utility model incorporates a rubber stop, mounting head one, mounting head two, and an air spring.

[0029] The following will refer to the appendix in the embodiments of this utility model. Figure 1-7 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0030] An intelligent shock absorber for electric hydraulic air suspension includes a housing 1. One end of the housing 1 is connected to an adjusting base tube 2, and a fixing plate 3 is embedded in one end of the housing 1. A retaining ring 4 is snapped into the inside of the fixing plate 3. A circular array of connecting bolts 5 are arranged through one side of the fixing plate 3. The retaining ring 4 is fixedly installed inside the fixing plate 3 by the connecting bolts 5. A circular array of connecting screws 6 are arranged through one side of the fixing plate 3. A nut 7 located outside the fixing plate 3 is threaded onto one end of the connecting screw 6. The fixing plate 3 is fixedly installed on the housing 1 by the connecting screw 6. A spring 8 is sleeved on the surface of the connecting screw 6. The two ends of the spring 8 are respectively fixedly connected to the connecting screw 6 and the inner wall of the housing 1.

[0031] The specific usage process is as follows: During installation, first insert the hydraulic shock absorber 14 into the bottom of the air spring 18, and then put the air spring 18 onto the housing 1. At the same time, the end of the hydraulic shock absorber 14 will also be inserted into the housing 1 and the adjusting base tube 2. Then loosen the nut 7, and then rotate the connecting screw 6 to remove the connecting screw 6 from the housing 1. In this way, the fixing plate 3 and the retaining ring 4 can move and adjust within the housing 1. It should be noted that the adjusting base tube 2 is installed inside the retaining ring 4, and the retaining ring 4 is engaged in the retaining groove 12 on the limiting slider 11. In this way, the adjusting base tube 2 can move and adjust together with the fixing plate 3. Therefore, during installation, first pull the adjusting base tube 2 outwards from the housing 1. 14 will also penetrate deeper into the housing 1, so that the hydraulic shock absorber 14 will not push up the air spring 18. The air spring 18 has enough space to contract, making it easier to press down. This makes it easier to install the rubber stop 15 later, because the air spring 18 can be compressed, and the user can have a point of force to pinch the air spring 18, thus better embedding the rubber stop 15 into the air spring 18. At the same time, the air spring 18 also has a larger deformation space when installed on the housing 1, making it easier to fit onto the housing 1. After the air spring 18 is fitted onto the housing 1, the rubber stop 15 is also embedded into the air spring 18. Then, push the adjusting bottom tube 2 back into the housing 1. The process continues until the adjusting base tube 2 moves the hydraulic shock absorber 14 back and lifts the rubber stop 15. The rubber stop 15 then unfolds the air spring 18 until the air spring 18 is fully extended and the adjusting base tube 2 can no longer be pushed. At this point, the fixing plate 3 and the retaining ring 4 will also move back to their original positions along with the adjusting base tube 2, and the connecting screw 6 will also move along with it, compressing the spring 8. Then, the connecting screw 6 is inserted into the corresponding threaded hole 13, and then the connecting screw 6 is rotated to tighten and fix it. After the connecting screw 6 is tightened and fixed, the spring 8 is also in a compressed state. At the same time, the spring 8 will also provide a reverse rebound force to the connecting screw 6, so that the threads on the surface of the connecting screw 6 and the threads in the threaded hole 13 are firmly locked together, preventing the connecting screw 6 from becoming loose and ensuring the smooth operation of the adjusting base tube 2. The stability of the base tube 2 after installation ensures the normal operation of the shock absorber and provides convenience for users. The threaded hole 9 is for inserting the connecting screw 6, and the through hole is for inserting the connecting bolt 5, facilitating installation. When adjusting the length of the base tube 2, the limiting slider 11 slides within the limiting groove 10, thus limiting the adjustment of the base tube 2 and ensuring its stability during adjustment. The retaining groove 12 is compatible with the retaining ring 4. During installation, the retaining ring 4 engages with the corresponding retaining groove 12 according to the actual installation length of the base tube 2. Finally, the fixing plate 3 is fixedly installed onto the housing 1 using the connecting screw 6.The installation and fixing of the adjusting base tube 2 is achieved, providing convenience for the user's installation work. The piston 143 is sleeved on the end of the shock absorber push rod 142 and slides tightly against the inner wall of the shock absorber housing 141. In this way, when the shock absorber push rod 142 slides inside the shock absorber housing 141, the sealing between the shock absorber push rod 142 and the shock absorber housing 141 is guaranteed, and air leakage is avoided. When the hydraulic shock absorber 14 is working, it receives the heavy pressure of the vehicle, and the shock absorber push rod 142 slides into the shock absorber housing 141. With the cooperation of the piston 143, it compresses the air inside the shock absorber housing 141. At the same time, with the cooperation of the rubber stop 15, it also compresses the air spring 18, thereby achieving the purpose of buffering and shock absorption. The rubber stop 15 is inserted into the air spring 18, and the rubber stop 15 is made of rubber. Made of rubber, it has a certain degree of elasticity, allowing it to cooperate with the air spring 18. This ensures the air spring 18 fits tightly against the rubber stop 15, guaranteeing its airtightness and preventing air leakage. This ensures the normal operation of the shock absorber. The air spring 18 is used for gas filling, enabling inflation and deflation via a control terminal. Mounting sleeve one 16 and mounting sleeve two 17 are used to fix the shock absorber to the frame, providing convenience for the user. Threaded hole two 13 is used to install the connecting screw 6. Both ends of the connecting screw 6 are threaded, allowing it to fix the fixing plate 3 to the housing 1, ensuring the stability of the adjusting base tube 2 after installation and providing convenience for the user.

[0032] Therefore, the shock absorber housing is designed to be flexibly adjustable. During installation, the length of the housing can be adjusted to save time and effort when installing the air spring, allowing for quick assembly of various components and increasing the installation speed of the shock absorber, thus providing convenience for users.

[0033] The fixed plate 3 has a threaded hole 9 on one side that is compatible with the connecting screw 6, and a through hole located inside the threaded hole 9 and compatible with the connecting bolt 5 on the other side.

[0034] Specifically, the threaded hole 9 and the through hole are designed so that the threaded hole 9 is used to insert and install the connecting screw 6, and the through hole is used to insert and install the connecting bolt 5, which provides convenience for the user's installation work.

[0035] The top and bottom of the inner cavity of the sleeve 1 are provided with limiting grooves 10, and the top and bottom of the adjusting bottom tube 2 are fixedly connected with limiting sliders 11 that are adapted to the limiting grooves 10.

[0036] Specifically, with the setting of the limiting slide groove 10 and the limiting slider 11, when adjusting the length of the adjusting base tube 2, the limiting slider 11 will also slide along the adjusting base tube 2 in the limiting slide groove 10, thus playing a limiting role for the adjusting base tube 2, ensuring the stability of the adjusting base tube 2 adjustment work, and providing convenience for the user's work.

[0037] The bottom of the limiting slider 11 is provided with equally spaced slots 12, and multiple slots 12 are adapted to the nut 7.

[0038] Specifically, the slot 12 is designed to fit the retaining ring 4. During installation, the adjusting base tube 2 is adjusted according to the actual installation length, and the retaining ring 4 will engage in the corresponding slot 12. Finally, the connecting screw 6 is used to fix the fixing plate 3 onto the housing 1, thereby achieving the installation and fixation of the adjusting base tube 2 and providing convenience for the user's installation work.

[0039] A hydraulic shock absorber 14 is provided inside the casing 1 and the adjusting bottom tube 2. The hydraulic shock absorber 14 includes a shock absorber housing 141. A shock absorber push rod 142 is slidably installed inside the shock absorber housing 141. A piston 143 located in the inner cavity of the shock absorber housing 141 is fixedly installed at one end of the surface of the shock absorber push rod 142.

[0040] Specifically, in the hydraulic shock absorber 14, the piston 143 is sleeved on the end of the shock absorber push rod 142 and slides close to the inner wall of the shock absorber housing 141. In this way, when the shock absorber push rod 142 slides inside the shock absorber housing 141, the sealing between the shock absorber push rod 142 and the shock absorber housing 141 can be guaranteed, and air leakage can be avoided. When the hydraulic shock absorber 14 is working, it receives the heavy pressure of the vehicle, and the shock absorber push rod 142 slides into the shock absorber housing 141. With the cooperation of the piston 143, it will compress the air inside the shock absorber housing 141. At the same time, with the cooperation of the rubber stop 15, it will also compress the air spring 18, thereby achieving the purpose of buffering and shock absorption.

[0041] An air spring 18 is fitted onto the surface of the housing 1. A rubber stop 15 is threaded onto one end of the shock absorber push rod 142 and inserted into the air spring 18. A mounting sleeve 16 located outside the air spring 18 is fixedly installed on one side of the rubber stop 15. A mounting sleeve 2 17 is fixedly installed on one end of the adjusting bottom tube 2.

[0042] Specifically, the rubber stop 15, mounting head one 16, mounting head two 17, and air spring 18 are configured such that the rubber stop 15 is inserted into the air spring 18, and the rubber stop 15 is made of rubber, which has a certain elasticity, so it can cooperate with the air spring 18, allowing the air spring 18 to fit tightly against the rubber stop 15, ensuring the air spring 18's sealing and preventing air leakage, thus ensuring the normal operation of the shock absorber. The air spring 18 is used to fill with gas, realizing inflation and deflation, and inflation and deflation are realized through the control end. Mounting head one 16 and mounting head two 17 are used to fix the shock absorber to the frame, providing convenience for the user's work.

[0043] One end of the inner side of the housing 1 is provided with threaded holes 13 arranged in a circular array, and the multiple threaded holes 13 are adapted to the connecting screw 6.

[0044] Specifically, the threaded hole 13 is used to install the connecting screw 6. Both ends of the connecting screw 6 are threaded, so the connecting screw 6 can fix the fixing plate 3 onto the housing 1, thereby ensuring the stability of the adjusting base tube 2 after installation and providing convenience for the user's work.
