[0002] Air spring as a kind of elastic element, in recent years, more and more use in passenger car, and the performance requirement of air spring of each host factory is increasing day by day, and the air spring of double-cavity form has become mainstream structure.

[0003] But rear air spring mainly relies on mounting seat and vehicle cantilever to connect, and the part mounting seat is used as important component in air spring, the existing mounting seat is integral, and the structure is relatively single, therefore, one kind of air spring can only be matched with this kind of mounting seat, and the types of air spring are various, so the types of mounting seat are more, so the design and development cost is large in air spring design and development.

[0004] The information disclosed in this BACKGROUND section is only for the purpose of increasing the understanding of the background of the present utility model and should not be construed as acknowledging that the information has been prior art to those skilled in the art prior to the filing date of the utility model. CONTENT OF THE UTILITY MODEL

[0005] The technical problem to be solved by the utility model is to solve the problem that mounting seat is not matched with different types of cantilevers.

[0006] The utility model solves the above technical problem by the following technical scheme:

[0007] The utility model requires protection of a split mounting seat, which comprises a split mounting seat body, the mounting seat body comprises at least a common section and a connecting section, wherein the common section is configured to be connected with a common platform, the connecting section is configured to be assembled with a cantilever, and the common section and the connecting section are detachably connected with each other.

[0008] Preferably, the connecting section comprises a fixing part and an assembling part, the bottom of the common platform is detachably connected with one end of the fixing part, the fixing part is coaxially arranged with the common platform, the assembling part is arranged at the other end of the fixing part, and the assembling part is assembled with the cantilever.

[0009] Preferably, the cantilever is provided with a mounting hole, and the assembling part is adapted to the mounting hole and is assembled with the mounting hole.

[0010] Preferably, the mounting hole is an elliptical hole structure.

[0011] Preferably, a circular hole is formed in the center of the bottom of the assembling part, and a fan-shaped hole is formed in the bottom of the assembling part outside the circular hole.

[0012] Preferably, the fan-shaped holes are arranged uniformly along the circumference of the circular hole, the wall thickness between the adjacent fan-shaped holes and the wall thickness between the fan-shaped holes and the circular hole are uniform, and the wall thicknesses are connected to form a mesh-shaped reinforcing rib.

[0013] Preferably, the mounting hole is a circular hole structure.

[0014] Preferably, the cantilever includes a lower swing arm and a lower control arm.

[0015] Preferably, the inner recess of the fixed portion side wall forms a gap with the mounting hole.

[0016] Preferably, the detachable connection includes a threaded connection or a cantilever buckle connection or a ring buckle connection or a latch connection or a friction fit connection.

[0017] The utility model has the advantages that:

[0018] Firstly, the utility model mainly considers the installation limitation problem of the air spring and the mounting seat body in actual production. In fact, there are various types of air springs on the market, but the types of mounting seat bodies are relatively single. When in use, only one type of air spring can be matched with a redesigned mounting seat body. This not only has high development cost, but also has a long storage and development cycle. Therefore, the mounting seat body is designed as a split type in the utility model, at least including a common section and a connecting section. The common section is an unchanged element connected with a common platform, so as to realize the standardization of the common section. In addition, the detachable connection between the common section and the connecting section is matched with the cantilever on different air springs, so as to realize the installation effect of the mounting seat body and different air springs. Of course, during actual assembly, the common section and the connecting section can be set as variable according to the actual situation, so as to increase the overall applicability. In addition to the above, compared with the prior art mounting seat, the utility model has the following two advantages. Advantage one: if the connecting section is scrapped, the common section can still be used by replacing other connecting sections, so as to improve the service life. Advantage two: any common section and connecting section can be combined to meet the early loading, rapid part manufacturing and part manufacturing efficiency improvement.

[0019] Secondly, the main function of the fixed portion is to ensure the detachable connection of the common section and the connecting section, and the function of the assembly portion is to provide an assembly position for the cantilever. Generally, there are various types of cantilevers, such as a lower swing arm and a lower control arm. During installation, corresponding mounting holes are arranged on the lower swing arm and the lower control arm. The shapes of the mounting holes are different based on the different types of cantilevers, such as circular holes or elliptical holes. At this time, the shape of the assembly portion also changes adaptively.

[0020] 3. When the mounting hole is an elliptical hole, based on the issues of weight reduction and venting, the bottom of the assembly part is provided with round holes and fan-shaped holes. Furthermore, considering the molding stability and shrinkage issues of the assembly part, it is preferable to ensure that the wall thickness of the hole between adjacent fan-shaped holes and the wall thickness of the hole between the fan-shaped hole and the round hole are uniform. Finally, the hole walls are connected to each other to form reinforcing ribs, which provide stable support for the assembly part and improve the strength of the components.

[0021] Fourth, the clearance is primarily to ensure the installation of the fixing part and the mounting hole. The assembly of the fixing part and the cantilever also involves limiting, positioning, and connecting structures, which are existing technologies for the installation of the cantilever and mounting base body and will not be elaborated further. The clearance is used to allow for the connection structure and provide an installation position.

[0022] V. Detachable connections can be selected according to actual needs, including threaded connections, cantilever snap-fit ​​connections, ring snap-fit ​​connections, pin connections, or friction fit connections. Generally speaking, the most commonly used connection is the threaded connection, which involves setting external threads on the surface of the fixed part and setting threaded holes in the common section. After they are engaged, thread-locking adhesive is applied to strengthen the fixation. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, 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.

[0032] Example 1

[0033] This embodiment claims protection for a split mounting base, including a split mounting base body 1. The mounting base body 1 includes at least a common section 11 and a connecting section 12. The common section 11 is configured to connect to a common platform, and the connecting section 12 is configured to be adapted and assembled with a cantilever. The common section 11 and the connecting section 12 are detachably connected to each other. The detachable connection includes threaded connection, cantilever snap-fit ​​connection, ring snap-fit ​​connection, pin connection, or friction fit connection. These are common connection methods in the prior art and will not be described in detail. Generally speaking, the most commonly used connection is the threaded connection, which is achieved by providing external threads on the surface of the fixing part 120 and threaded holes on the common section 11. After they are engaged, thread-locking adhesive is applied to strengthen the fixation. The main function of the fixing part 120 is to ensure the detachable connection between the common section 11 and the connecting section 12, while the function of the assembly part is to provide an assembly position for the cantilever. Generally speaking, there are many types of cantilever, such as the lower swing arm 2 and the lower control arm 3. During installation, corresponding mounting holes are provided on the lower swing arm 2 and the lower control arm 3. The shape of the mounting holes is also different depending on the type of cantilever, such as circular holes or elliptical holes. At this time, the shape of the assembly part will also change accordingly.

[0034] Furthermore, the connecting section 12 includes a fixing part 120 and an assembly part. One end of the fixing part 120 is detachably connected to the bottom of the common platform. The fixing part 120 is coaxially arranged with the common platform. The other end of the fixing part 120 is provided with the assembly part, which is adapted to the cantilever for assembly. The cantilever is provided with mounting holes. The outer contour of the assembly part is adapted to the mounting holes and they are assembled together. The side wall of the fixing part 120 is recessed to form a gap with the mounting holes. The gap is mainly to ensure the installation of the fixing part 120 and the mounting holes. In the assembly of the fixing part 120 and the cantilever, limiting, positioning and connection structures are also involved. This is the existing technology for the installation of the cantilever and the mounting base body 1, and will not be described in detail. The gap is used to avoid the connection structure and provide the installation position. In actual production, the cantilever can be a lower swing arm 2. The mounting hole on the lower swing arm 2 is defined as the first mounting hole 2a. The first mounting hole 2a is generally a circular hole structure. The mounting part adapted to the first mounting hole 2a and assembled together is defined as the first assembly part 12a.

[0035] Example 2

[0036] The difference between this embodiment and Embodiment 1 is that the cantilever is a lower control arm 3, and the mounting hole provided on the lower control arm 3 is defined as a second mounting hole 3b. The second mounting hole 3b is generally an elliptical hole structure, and the mounting part that is adapted to and assembled with the second mounting hole 3b is defined as a second assembly part 12b. A circular hole 120b is opened at the center of the bottom of the second assembly part 12b, and a fan-shaped hole 121b is opened at the bottom of the assembly part located outside the circular hole 120b. There are several fan-shaped holes 121b, which are evenly arranged around the circumference of the circular hole 120b. The wall thickness of the holes between adjacent fan-shaped holes 121b and between the fan-shaped holes 121b and the circular hole 120b is uniform, and they are connected to each other to form a mesh of reinforcing ribs 122b. Based on the issues of weight reduction and venting, the bottom of the second assembly part 12b is provided with circular holes 120b and fan-shaped holes 121b. Furthermore, considering the molding stability and shrinkage issues of the second assembly part 12b, it is preferable to ensure that the wall thickness of the holes between adjacent fan-shaped holes 121b and between the fan-shaped holes 121b and the circular hole 120b is uniform. Finally, the hole walls are connected to each other to form reinforcing ribs 122b, which provide stable support for the second assembly part 12b and improve the strength of the components.

[0037] This utility model addresses the limitation of air spring installation on the mounting base 1 in actual production. In reality, there are many types of air springs on the market, while the types of mounting base 1 are relatively limited. When using an air spring, a corresponding mounting base 1 must be designed to fit it, resulting in high development costs and long development and storage cycles. Therefore, this utility model designs the mounting base 1 as a split type, including at least a common section 11 and a connecting section 12. The common section 11 serves as a constant component for connecting to a common platform, thus standardizing the common section 11. Furthermore, the common section 11 and the connecting section 12 are detachably connected, allowing the connecting section 12 to be adapted to the cantilever on different air springs, achieving the effect of installing the mounting base 1 with different air springs. Of course, in actual assembly, both the common section 11 and the connecting section 12 can be made variable to increase overall applicability, depending on the specific circumstances. In addition, compared to existing mounting technologies, it has the following two advantages: Advantage 1: If the connecting section 12 is scrapped, the common section 11 can still be used by replacing it with another connecting section 12, extending its service life. Advantage 2: Any common section 11 and connecting section 12 can be combined, meeting the requirements of early vehicle assembly, rapid component manufacturing, and improved component manufacturing efficiency.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
