Description

Technical Field

[0001] This utility model belongs to the field of automotive component technology, specifically relating to a shock absorber connecting plate assembly bushing. Background Technology

[0002] Shock absorbers are automotive parts that suppress the impact force caused by the rebound of spring vibrations. They play a key role in the car's suspension system. When installing a typical shock absorber, a connecting plate is used to install and fix both ends of the shock absorber. The connecting plate contains a bushing, which is located between the connecting plate and the shock absorber and serves as a connection. Existing bushings mainly consist of a frame and a rubber layer installed on the outside of the frame. The frame and rubber layer facilitate the connection of the bushing with other components and increase the stability of the connection between the shock absorber and the connecting plate.

[0003] Chinese utility model patent document CN219755191U discloses a type of shock absorber top connecting plate assembly bushing, including a first frame, the internal structure of the first frame having a connecting cavity, a second frame provided on the outer surface of the first frame, an inner bushing provided on the outer surface of the second frame, multiple sets of first contact blocks installed on the top of the inner bushing, and a second contact block installed on the side of the first contact block on the top of the inner bushing.

[0004] The aforementioned bushing, through the establishment of the first and second contact blocks, can gradually increase the contact area between the bushing and the connecting plate, thereby improving the vibration isolation comfort of the bushing. However, in actual use, the second contact block is entirely planar, resulting in the bushing only having two contact methods during operation. The first method is that the first contact block is in contact with the connecting block, and the second method is that both the first and second contact blocks are in contact with the connecting block. Although there is a transition between the two methods, the transition curve is not smooth enough, affecting the actual use effect of the bushing itself. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problems mentioned in the background section, the present invention adopts the following technical solution.

[0007] A shock absorber connecting plate assembly bushing includes a bushing body and a middle frame. The middle frame is installed inside the bushing body. The bushing body is mainly composed of two sets of symmetrically arranged conical rubber rings. The ends of the conical rubber rings are in extrusion contact with the inner wall of the connecting plate. The upper and lower ends of the bushing body are equipped with contact ends that gradually increase the contact area with the connecting plate according to the change of extrusion force.

[0008] As a preferred technical solution of this utility model, the contact end includes an adhesive layer, a raised extrusion plate and a wear-resistant spherical part. The adhesive layer is symmetrically installed at the upper and lower ends of the bushing body. The wear-resistant spherical parts are installed at equal intervals on the upper surface of the adhesive layer. The raised extrusion plate is installed at equal intervals on the surface of the adhesive layer. The raised extrusion plate is bonded to the inner wall of the connecting plate by contacting the inner wall. The wear-resistant spherical part is bonded to the inner wall of the connecting plate by point contact.

[0009] As a preferred embodiment of this utility model, the bonding layer is a conical plate structure with an opening in the middle and an upward protrusion at the middle end, and the horizontal height at the edge of the bonding layer is lower than the horizontal height at the middle end of the bonding layer.

[0010] As a preferred technical solution of this utility model, the contact end includes a contact layer, an extrusion protrusion, and a contact spherical block. The contact layer is symmetrically installed at the upper and lower ends of the bushing body, and the contact spherical blocks are equidistantly installed at the edge of the contact layer surface. The extrusion protrusion is equidistantly installed on the contact layer surface.

[0011] As a preferred technical solution of this utility model, the contact layer is a conical plate structure with a concave middle and an open middle, and the extrusion protrusion is installed on the inner wall of the concave area of ​​the contact layer, and the distance between adjacent extrusion protrusions is less than the length of the extrusion protrusion itself.

[0012] As a preferred technical solution of this utility model, it also includes anti-slip components. Anti-slip components are installed at equal intervals on the side wall of the bushing body to increase the contact area and friction between the side wall area of ​​the bushing body and the connecting plate.

[0013] As a preferred technical solution of this utility model, the anti-slip component mainly consists of a supporting rectangular part and a raised spherical part. The supporting rectangular part is connected to the inner wall of the conical rubber ring, and multiple sets of raised spherical parts are provided. The raised spherical parts are installed on the side wall of the supporting rectangular part.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention, by incorporating a contact end and an anti-slip component, ensures the stability of the bushing and connecting plate during use while gradually increasing the contact area between the contact end and the connecting plate according to changes in the compressive force. The contact end in this invention includes an adhesive layer, a raised extrusion plate, and a wear-resistant spherical portion. When the connecting plate and the shock absorber are in operation, the raised extrusion plate first makes surface contact with the inner wall of the connecting plate. Then, as the compressive force increases, the adhesive layer deforms as a whole, driving the wear-resistant spherical portion to contact the interior of the connecting plate, thus increasing the friction between the connecting plate and the bushing. The curve of size variation is smoother, providing a stable vibration isolation effect for the shock absorber; the contact end of this utility model also includes a contact layer, an extrusion convex plate and a contact spherical block. In use, the contact spherical block first fits against the inner wall of the connecting plate. At this time, the bushing and the connecting plate are in point contact. Then, according to the increase of the extrusion force, the contact layer deforms, and the extrusion convex plate in the concave area of ​​the contact layer makes surface contact with the inner wall of the connecting plate. Furthermore, the extrusion convex plate will deform due to extrusion, extruding the extrusion convex plate position on the west side, thereby ensuring the stability of the bushing during use.

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0025] Example 1: like Figure 1 , Figure 2 and Figure 3 As shown, this is a structural schematic diagram of the shock absorber connecting plate and bushing assembly in this embodiment. The bushing in this utility model is fitted inside the connecting plate to provide vibration isolation for the connection between the connecting plate and the shock absorber, ensuring the working quality of the bushing itself. The bushing includes a bushing body 1 and a middle frame 2. The bushing body 1 is installed outside the bushing body 1. The bushing body 1 is made entirely of rubber material, and the bushing body 1 is mainly composed of two sets of symmetrically arranged conical rubber rings. The sidewalls of the conical rubber rings fit against the inner wall of the connecting plate. The middle frame 2 provides convenience for the insertion of the shock absorber end, allowing the shock absorber to be stably connected to the connecting plate.

[0026] When installing the bushing, the connecting plate is disassembled, and then the entire bushing is inserted between the disassembled connecting plates. The position of the bushing is locked by closing the connecting plate. The middle frame 2 and the connecting plate are provided with a connecting groove for connecting the end of the edge shock absorber.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, anti-slip components 4 are installed at equal intervals on the side wall of the conical rubber ring. The anti-slip components 4 consist of a supporting rectangular part and a raised spherical part. The supporting rectangular part is connected to the inner wall of the conical rubber ring. Multiple sets of raised spherical parts are provided. The raised spherical parts are installed on the side wall of the supporting rectangular part and fit against the inner wall of the connecting plate to enhance the stability when the bushing is connected to the connecting plate.

[0028] As attached Figure 4 and Figure 5As shown, this is a schematic diagram of the contact end 3 in this embodiment. The contact end 3 in this embodiment includes an adhesive layer 31, a raised extrusion plate 32, and a wear-resistant spherical part 33. The adhesive layer 31 is symmetrically installed at the upper and lower ends of the bushing body 1. The adhesive layer 31 is a cone-shaped structure with an opening in the middle and a protrusion upward. The raised extrusion plate 32 is installed at equal intervals on the upper surface of the adhesive layer 31. The raised extrusion plate 32 is attached to the inner wall of the connecting plate. When the connecting plate or the shock absorber is running, the raised extrusion plate 32 is compressed first. As the extrusion force increases, the adhesive layer 31 deforms as a whole, causing the part of the adhesive layer 31 that was originally raised in the middle to be recessed at the bottom. In addition, multiple sets of wear-resistant spherical parts 33 are installed on the upper surface of the adhesive layer 31. As the curvature and shape of the adhesive layer 31 change, the number of wear-resistant spherical parts 33 attached to the inner wall of the connecting plate gradually increases, thereby forming a gradient vibration isolation effect and making the overall vibration isolation curve smoother.

[0029] It is worth noting that the horizontal position of the protrusion of the protrusion of the protrusion of the protrusion of the protrusion of the middle part of the bonding layer 31 is at the same horizontal line as the highest point of the protrusion in the middle part of the bonding layer 31, so that the middle part of the bonding layer 31 and the surface of the protrusion ...

[0030] Example 2: like Figure 1 , Figure 2 and Figure 3 As shown, this is a structural schematic diagram of the shock absorber connecting plate and bushing assembly in this embodiment. The bushing in this utility model is fitted inside the connecting plate to provide vibration isolation for the connection between the connecting plate and the shock absorber, ensuring the working quality of the bushing itself. The bushing includes a bushing body 1 and a middle frame 2. The bushing body 1 is installed outside the bushing body 1. The bushing body 1 is made entirely of rubber material, and the bushing body 1 is mainly composed of two sets of symmetrically arranged conical rubber rings. The sidewalls of the conical rubber rings fit against the inner wall of the connecting plate. The middle frame 2 provides convenience for the insertion of the shock absorber end, allowing the shock absorber to be stably connected to the connecting plate.

[0031] When installing the bushing, the connecting plate is disassembled, and then the entire bushing is inserted between the disassembled connecting plates. The position of the bushing is locked by closing the connecting plate. The middle frame 2 and the connecting plate are provided with a connecting groove for connecting the end of the edge shock absorber.

[0032] like Figure 1 , Figure 2 and Figure 3 As shown, anti-slip components 4 are installed at equal intervals on the side wall of the conical rubber ring. The anti-slip components 4 consist of a supporting rectangular part and a raised spherical part. The supporting rectangular part is connected to the inner wall of the conical rubber ring. Multiple sets of raised spherical parts are provided. The raised spherical parts are installed on the side wall of the supporting rectangular part and fit against the inner wall of the connecting plate to enhance the stability when the bushing is connected to the connecting plate.

[0033] As attached Figure 6 As shown, this is a schematic diagram of the contact end 3 in this embodiment. To further increase the initial contact area when the contact end 3 contacts the inner wall of the connecting plate, the contact end 3 in this embodiment includes a contact layer 34, a pressing protrusion 35, and a contact spherical block 36. Contact layers 34 are installed at both the upper and lower ends of the bushing body 1. The contact layer 34 is a conical structure with an opening in the middle and a recessed bottom. Contact spherical blocks 36 are equidistantly installed on the surface of the contact layer 34. The contact spherical blocks 36 are pressed against the inner wall of the connecting plate. A pressing protrusion 35 is installed on the inner wall of the recessed area of ​​the contact layer 34. 5. Multiple sets are provided, and the distance between adjacent extrusion protrusions 35 is less than the length of the extrusion protrusions 35 themselves. In use, the contact ball block 36 first fits against the inner wall of the connecting plate. As the extrusion force increases, the contact layer 34 deforms as a whole, causing the protruding part at the edge of the contact layer 34 to move towards the bottom. This allows the extrusion protrusions 35 in the concave area of ​​the middle of the contact layer 34 to contact the inner wall of the connecting plate one by one. When the extrusion protrusion 35 is extruded, the angle and shape of the extrusion protrusion 35 itself change, and the same extrusion is applied to the next set of extrusion protrusions 35, thereby achieving a smoother vibration isolation curve.

[0034] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
