Detailed Implementation

[0016] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application will be described in detail below with reference to the accompanying drawings. First, it should be noted that the directional terms such as up, down, left, right, front, back, inner, outer, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive terms. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In this application, unless otherwise expressly specified and limited, the term "fixed" and similar terms should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0018] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "example," "specific example," "some examples," or "possible implementation," etc., refer to specific features, structures, materials, or characteristics described in connection with that embodiment or example, which are included in at least one embodiment or example of the embodiments of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples. Furthermore, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0019] This application proposes a shock-absorbing assembly for a device housing. A mounting hole 110 is provided through the device housing 10 along a first direction. End faces 111 are provided at opposite ends of the mounting hole 110 around the periphery of the first direction. The end faces 111 extend perpendicular to the first direction. Figures 1 to 3 As shown. It should be noted that, in this document, the term "first direction" can refer to the axial direction of the mounting hole 110. The damping assembly 200 according to this application comprises a rigid sleeve 210, an elastic damping element 220, and a rigid end cap 230, etc. The sleeve 210 is configured for installation within the mounting hole 110. The damping element 220 may be made of an elastic material such as rubber and includes a damping body 221 and a damping inner ring 222, wherein the damping body 221 is mounted at the end of the sleeve 210, and the damping inner ring 222 extends from the damping body 221 in the first direction, and the damping inner ring 222 is located between the sleeve 210 and the inner wall 112 of the mounting hole 110. Furthermore, the damping body 221 is spaced between the end cap 230 and the end face 111. In summary, the shock-absorbing component of this application uses components with different deformation capabilities—elastic components deform more than rigid components under the same force, and can elastically recover their original shape when the force is weakened; therefore, when the equipment is running, the shock-absorbing component can effectively block the vibration generated by the equipment shell from being transmitted outward.

[0020] In other optional embodiments, in conjunction with the above embodiments, the inner shock-absorbing ring 222 has a hole extending through the shock-absorbing element 220 along the first direction, and the sleeve 210 passes through the hole and abuts against the end cap 230. Of course, in addition to the sleeve 210 passing through the hole and abutting against the end cap 230, the sleeve 210 can also directly abut against the shock-absorbing body 221 of the shock-absorbing element 220, and no specific limitation is made here.

[0021] Continue to refer to Figures 4 to 5The damping element 220 may further include a damping outer ring 223, wherein the damping outer ring 223 extends from the damping body 221 in the first direction and is spaced apart from the damping inner ring 222, wherein the damping outer ring 223 is located on the outer wall 113 of the equipment housing 10 where the mounting hole 110 is located. That is, the mounting hole 110 is typically designed as a cylindrical structure, which may be a mounting boss 100 of the equipment housing 10. In this case, the inner wall 112 and the outer wall 113 of the mounting hole 110 are arranged opposite to each other and are both perpendicular to the end face 111.

[0022] Furthermore, the end cap 230 can be installed on the outside of the damping element 220 and abut against the end of the sleeve 210 by means of insertion or bonding, so that the sleeve 210 can be fixed in a designated position along its axial direction, thereby providing axial limitation for the sleeve 210. Here, the end cap 230 can both serve as a limiting member for the sleeve 210, constraining the position of the sleeve 210, and prevent the damping element 220 from bulging when subjected to axial compressive force, thereby ensuring the structural stability and performance of the damping element 220.

[0023] Those skilled in the art will readily understand that the outer shock-absorbing ring 223 is pressed tightly against the outer wall 113 of the equipment housing 10 where the end cap 230 and the mounting hole 110 are located. Furthermore, the inner shock-absorbing ring 222 is pressed tightly against the inner wall 112 of the sleeve 210 and the mounting hole 110, allowing the shock-absorbing element 220 to completely cover the end of the mounting hole 110, thereby better absorbing the energy generated by the vibration of the equipment housing 10 to the shock-absorbing element 220.

[0024] Continue to refer to Figures 6 to 9 To allow sufficient space for the elastic deformation of the damping element 220, the surface of the inner damping ring 222 is designed with a wavy structure, and the surface of the outer damping ring 223 is also designed with a wavy structure. Of course, in addition to the aforementioned wavy structure, the surfaces of the inner damping ring 222 and the outer damping ring 223 can also be designed with sawtooth, square, or trapezoidal wave structures, etc., without specific limitations.

[0025] Furthermore, both the end cap 230 and the sleeve 210 can be made of high-strength steel, thus enabling them to withstand larger loads. When the damping element 220 is encapsulated in the end cap 230, it can prevent the damping element 220 from bulging under load and improve the overall stability of the system.

[0026] Additionally, this application also provides a compressor housing, which is provided with the aforementioned shock-absorbing component 200, and the compressor housing is an embodiment of the aforementioned device housing 10. Specifically, a mounting hole 110 for installation is provided through the compressor housing along a first direction, and end faces 111 are provided around the mounting hole 110 at opposite ends in the first direction, the end faces 111 extending perpendicular to the first direction. Specifically, the compressor housing has a mounting boss 100, which is provided with the mounting hole 110. The mounting boss 100 can be mounted, for example, at a vehicle mounting seat 20 by bolts 300. The inner wall 112 of the mounting hole 110 is provided with a first step portion 114 for accommodating the shock-absorbing inner ring 222 of the shock-absorbing element 220, such as... Figures 7 to 9 As shown. Of course, in addition to the stepped portion on the inner wall 112 of the mounting hole 110, the outer wall 113 of the compressor housing where the mounting hole 110 is located is provided with a second stepped portion 115, as shown. Figure 2 As shown.

[0027] It should be noted that the shock absorption assembly provided in this application has a buffering and shock absorption function, which can effectively absorb some of the energy generated by the compressor's vibration during operation, reducing the impact force transmitted to the vehicle, thereby achieving a good buffering effect. Specifically, the shock absorption element in the shock absorption assembly can generate adaptive elastic deformation according to the actual vibration of the compressor housing, further absorbing vibration energy through the deformation process and enhancing the shock absorption effect. In addition, the shock absorption assembly can also prevent the sleeve from directly contacting the inner diameter of the vehicle's mounting seat, thereby ensuring complete decoupling between the sleeve and the compressor (i.e., the compressor housing). This decoupling is indispensable for cutting off the vibration transmission path between the compressor and the vehicle interface. At the same time, the shock absorption element can also play a role in radial centering of the sleeve, and the sleeve can ensure precise centering when the bolt is fixed to the sleeve, and effectively prevent the shock absorption element from being subjected to excessive compression in the axial direction during the operation of tightening the compressor to the vehicle interface.

[0028] Furthermore, this application also provides a compressor configured with the aforementioned compressor housing. For example, the compressor may be an electric compressor installed in a vehicle, such as a scroll compressor.

[0029] In summary, the shock-absorbing component for equipment housing according to this application can provide additional cushioning during equipment operation, reducing the impact force directly transmitted from the equipment body to the housing.

[0030] The foregoing has provided several specific embodiments to illustrate in detail the shock-absorbing assembly for equipment housing, the compressor housing in which the shock-absorbing assembly is provided, and the compressor in which the compressor housing is provided. These examples are only for illustrating the principles and implementation methods of this application and are not intended to limit the application. Various modifications and improvements can be made by those skilled in the art without departing from the spirit and scope of this application. Therefore, all equivalent technical solutions should fall within the scope of this application and be defined by the claims of this application.
