Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive shock absorption equipment technology, and in particular to a two-in-one bipolar shock absorber bracket that can effectively reduce the vibration of an air compressor. Background Technology
[0002] An air suspension system is a car suspension technology that uses air as a damping element. Through the coordinated work of components such as an air compressor, accumulator, control unit, and sensors, it can precisely adjust the vehicle height, elasticity, and damping effect.
[0003] In air suspension systems, brackets are required to support the air compressor, and these brackets must possess sufficient stability to reduce the impact of vibrations generated by the air compressor during operation on the entire air suspension system. Currently, commonly used air compressor brackets are mainly divided into single-stage damping brackets and two-stage damping brackets. For example... Figure 1 As shown, the single-stage damping bracket includes a limiting pin 1, which has an outward-facing groove. A primary damping buffer block 2 is installed inside the groove. A primary damping pad 3 is provided on the top of the limiting pin 1, and a primary damping bolt 4 passes through the primary damping pad 3 and the limiting pin 1. Figure 2 As shown, the secondary damping bracket includes a limiting shim 5, a primary damping structure 6, a secondary damping spring bushing 7, a secondary damping spring 8, a bolt bushing 9, and a secondary damping bolt 10.
[0004] However, single-stage shock absorber brackets, which use a single-stage damping pad as a buffer, have a relatively simple structure but can only isolate compressor vibrations of a specific frequency, resulting in poor damping performance. Two-stage shock absorber brackets, on the other hand, can attenuate vibrations from multiple frequencies of the air compressor, but they have more components, are difficult to manufacture, occupy more space, and are difficult to install during use. Furthermore, both single-stage and two-stage shock absorber brackets require pre-embedded or welded pre-mounted bolts at designated locations during the vehicle design phase as mounting anchor points. These pre-mounted bolts rely on pre-tightening force during installation, and long-term vibration can easily cause them to loosen, posing a risk of them falling off. Utility Model Content
[0005] This invention provides a two-in-one bipolar vibration damping bracket that can effectively reduce the vibration of an air compressor, thereby solving the technical problems of single-stage vibration damping brackets having a single vibration damping frequency band and two-stage vibration damping brackets having complex structures, difficult production, and limited layout.
[0006] To solve the above problems, the two-in-one bipolar vibration damping bracket provided by this utility model, which can effectively reduce the vibration of air compressors, adopts the following technical solution:
[0007] A two-in-one bipolar vibration damping bracket that can effectively reduce the vibration of an air compressor includes an adapter, a limiting pin, a vibration damping bolt, an elastic vibration damping component, and a buffer pad. The adapter is provided with threaded holes for screwing on the vibration damping bolt.
[0008] The limiting pin has a U-shaped mounting position extending vertically for mounting the shock-absorbing bolt, and the bottom of the U-shaped mounting position has a mounting hole for the shock-absorbing bolt to pass through.
[0009] The outer periphery of the limiting pin has a mounting groove for mounting the elastic damping element;
[0010] A shock-absorbing spring is fitted onto the shock-absorbing bolt, and a spring bushing is provided in the U-shaped mounting position. The shock-absorbing spring is located between the head of the shock-absorbing bolt and the bottom surface of the spring bushing.
[0011] The buffer pad is located at the bottom of the limiting pin and has a through hole for the shock-absorbing bolt to pass through.
[0012] The beneficial effects of the two-in-one bipolar vibration damping bracket provided by this utility model, which can effectively reduce the vibration of air compressors, are:
[0013] 1. By installing elastic damping components on the outer periphery of the limit pin, primary damping can be achieved through the elastic damping components, and secondary damping can be achieved through the damping bolt, the spring bushing installed in the U-shaped mounting position, the damping spring fitted on the damping bolt, and the buffer pad located at the bottom of the limit pin, thereby achieving the purpose of integrating the single-stage damping bracket and the secondary damping bracket into a single damping bracket.
[0014] 2. Compared with the existing single-stage shock absorber bracket, the first-stage shock absorber in this utility model reduces the use of shock absorber bolts and shock absorber shims. Compared with the existing two-stage shock absorber bracket, the two-stage shock absorber in this utility model reduces the use of bolt bushings and limiting shims. The structure is simpler and easier to manufacture.
[0015] 3. The primary and secondary damping functions are integrated into one damping bracket, with the secondary damping located within the primary damping, which greatly saves the space required for the damping bracket to be arranged in the X, Y, and Z directions on the air compressor.
[0016] In summary, this utility model effectively solves the technical problems of single-stage damping brackets having a limited damping frequency band and two-stage damping brackets having complex structures, difficult production, and limited layout in the prior art.
[0017] Furthermore, the limiting pin includes a first limiting pin and a second limiting pin arranged from top to bottom, and the first limiting pin and the second limiting pin are detachably connected.
[0018] Furthermore, the first limiting pin is a threaded limiting pin, and the second limiting pin is a threaded hole limiting pin.
[0019] Beneficial effects: The first limiting pin is a threaded limiting pin, and the second limiting pin is a threaded hole limiting pin. The overall height of the limiting pin can be flexibly adjusted by adjusting the degree of screwing of the threaded limiting pin into the threaded hole limiting pin, thus expanding the applicable range of the limiting pin.
[0020] Furthermore, the top surface of the spring bushing has a horizontally extending outer edge, the bottom surface of the outer edge has a downwardly extending first limiting member, and the top of the limiting pin has a first limiting groove that matches the first limiting member.
[0021] Furthermore, the top surface of the buffer pad has a second limiting member, and the bottom surface of the limiting pin has a second limiting groove that matches the second limiting member.
[0022] Furthermore, the top surface, bottom surface, and side away from the limiting pin of the elastic damping member all have outward-facing slots to release concentrated stress generated during vibration.
[0023] Furthermore, the elastic damping element is a damping rubber block.
[0024] Furthermore, the buffer pad is a rubber pad.
[0025] Furthermore, the adapter includes a horizontal section and a vertical section, the threaded hole is provided on the horizontal section, the vertical section has a mounting surface, and a hook is provided on the mounting surface for attaching the adapter to the vehicle body.
[0026] Furthermore, the adapter has mounting holes for installing fastening bolts, and the vehicle body has corresponding threaded holes for connecting the adapter and the vehicle body through fastening bolts that pass through the mounting holes and are screwed into the threaded holes.

[0037] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.
[0038] An embodiment of the two-in-one bipolar vibration damping bracket that effectively reduces the vibration of an air compressor provided by this utility model:
[0039] like Figure 3 As shown, the two-in-one bipolar shock absorber bracket that can effectively reduce the vibration of the air compressor includes a limit pin 1, a shock absorber bolt 11, an elastic shock absorber and a buffer pad.
[0040] The limiting pin 1 has an outer periphery with a mounting groove for installing an elastic damping component to achieve primary damping through the elastic damping component; the limiting pin 1 has a U-shaped mounting position extending vertically for installing a damping bolt 11, the bottom of the U-shaped mounting position has a mounting hole for the damping bolt 11 to pass through, a buffer pad is provided at the bottom of the limiting pin 1 and has a through hole for the damping bolt 11 to pass through, a damping spring 12 is fitted on the damping bolt 11, and a spring bushing 13 is also provided in the U-shaped mounting position, the damping spring 12 is located between the head of the damping bolt 11 and the bottom surface of the spring bushing 13, so as to achieve secondary damping through the damping bolt 11, the spring bushing 13, the damping spring 12 and the buffer pad.
[0041] To limit the displacement of the spring bushing 13 and the buffer pad during use, the top surface of the spring bushing 13 has a horizontally extending outer edge 16, the bottom surface of the outer edge 16 has a downwardly extending first limiting member 17, and the top of the limiting pin 1 has a first limiting groove that matches the first limiting member 17; the top surface of the buffer pad has an upwardly extending second limiting member 18, and the bottom surface of the limiting pin 1 has a second limiting groove that matches the second limiting member 18.
[0042] In order to release the concentrated stress generated during vibration and prevent the elastic damping component from cracking due to excessive local stress, the top surface, bottom surface and the side away from the limiting pin of the elastic damping component are provided with outward-facing slots 21.
[0043] In this embodiment, the limiting pin 1 includes a first limiting pin and a second limiting pin arranged from top to bottom, and the first limiting pin and the second limiting pin are detachably connected. Specifically, the first limiting pin is a threaded limiting pin 14, and the second limiting pin is a threaded hole limiting pin 15, with the first limiting pin screwed into the second limiting pin. In other embodiments, the limiting pin 1 is an integral structure, or the first limiting pin is inserted into the second limiting pin.
[0044] In this embodiment, the buffer pad is a rubber pad 19, and the elastic damping element is a damping rubber block 20.
[0045] Furthermore, the two-in-one bipolar vibration damping bracket provided by this utility model, which effectively reduces the vibration of an air compressor, also includes an adapter, on which threaded holes 22 for screwing on the vibration damping bolts 11 are provided; such as Figure 4 and Figure 5 As shown, the adapter includes a horizontal section 23 and a vertical section 24. A threaded hole 22 is provided on the horizontal section 23, and the vertical section 24 has a mounting surface with a hook 25. A hanging hole is provided on the vehicle body. The adapter is hung on the vehicle body by hanging the hook 25 in the hanging hole. The adapter has a mounting hole 26 for installing fastening bolts, and a corresponding threaded mounting hole is provided on the vehicle body to connect the adapter and the vehicle body by fastening bolts that pass through the mounting hole 26 and are screwed into the threaded mounting hole, thereby enhancing the connection between the adapter and the vehicle body.
[0046] In this embodiment, the mounting hole 26 on the adapter is located at the junction of the horizontal segment 23 and the vertical segment 24. In other embodiments, the mounting hole 26 is located on the vertical segment 24.
[0047] like Figures 4 to 6 As shown, in the prior art, the connecting bracket 27 requires at least four single-stage damping mounting points 28 and three secondary damping mounting points 29. However, in the two-in-one bipolar damping bracket provided by this utility model, only three to four damping mounting points need to be set on the adapter, which greatly saves the space for the bracket to be arranged in the X and Y directions on the air compressor.
[0048] like Figure 7 As shown, in the prior art, the single-stage and two-stage vibration damping brackets are directly connected to the air compressor. In this case, the primary vibration damping bolt 4 of the vibration damping bracket may be directly above the air compressor. To prevent interference between the air compressor and the primary vibration damping bolt 4, a recessed structure needs to be constructed at the installation location when arranging the secondary vibration damping bracket, which inevitably occupies space in the Z-direction. Figure 4 and Figure 5 As shown, the two-in-one bipolar shock absorber bracket provided by this utility model places the secondary shock absorber bracket inside the primary shock absorber bracket, and the two share a common installation reference plane. The connection point (bolt position) between the compressor and the single-unit shock absorber bracket no longer needs to avoid the secondary shock absorber bracket, thereby avoiding the occupation of the headphone bracket in the Z-direction space and greatly saving the Z-direction arrangement space.
[0049] The working principle of the two-in-one bipolar shock absorber bracket provided by this utility model, which can effectively reduce the vibration of the air compressor, is as follows: The adapter is hung in the hanging hole opened on the vehicle body through the hook 25, and the fastening bolt is passed through the mounting hole 26 and screwed into the threaded mounting hole on the vehicle body to complete the installation of the two-in-one bipolar shock absorber bracket on the vehicle body. In use, the shock-absorbing rubber block 20 absorbs the low-frequency, large-amplitude energy to achieve primary shock absorption, and the rubber pad 19, shock-absorbing bolt 11, shock-absorbing spring 12 and spring bushing 13 handle the high-frequency, small-amplitude residual vibration to achieve secondary shock absorption. The combined effect of primary and secondary shock absorption absorbs various vibrations of different frequencies from the horizontal and vertical directions to ensure the stable operation of the air compressor.
[0050] Based on the above description in this specification, those skilled in the art will also understand that the following terms used, such as "upper," "lower," "front," "rear," "left," "right," "width," "horizontal," "top," "bottom," "inner," and "outer," are terms indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not explicitly or implicitly suggest that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.
[0051] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.
