Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0024] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0025] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0029] See Figures 1 to 3 , Figure 1 A schematic diagram of a cab suspension bracket mounting device 1 according to an embodiment of this application is shown. The mounting device 1 provided in this embodiment is used to connect a first suspension bracket disposed in the cab and a second suspension bracket (not shown) disposed on the vehicle frame. The mounting device 1 can be used in vehicles and in cab suspension assemblies within vehicles, particularly in cab suspension brackets of heavy vehicles. The mounting device 1 includes a first mounting member 100 and a second mounting member.

[0030] A first mounting member 100 connects to the first suspension bracket, and the first mounting member 100 includes a first assembly portion 121 and a second assembly portion 122. A second mounting member 200 connects to the second suspension bracket and is capable of connecting to the first mounting member 100. The second mounting member 200 includes a first positioning portion 210 and a second positioning portion 220, which respectively match the positions of the first assembly portion 121 and the second assembly portion 122. The first positioning portion 210 is disposed along a first direction X, and the second positioning portion 220 is disposed along a second direction Y, wherein the first direction X and the second direction Y are different. The first positioning portion 210 and the second positioning portion 220 are respectively connected to the first assembly portion 121 and the second assembly portion 122 to connect the first mounting member 100 and the second mounting member 200. Through the assembly portion of the first mounting member 100 and the positioning portion of the second mounting member 200, the first suspension bracket and the second suspension bracket can be limited and positioned in at least two directions. This limiting and positioning installation method significantly improves the accuracy of the connection between the first suspension bracket and the second suspension bracket. By ensuring the precise positioning of these two brackets during installation, the connection quality and stability between the cab and the frame are effectively improved. This installation method not only simplifies and enhances the installation process but also optimizes the overall vehicle structure, improving the driving experience and driving safety.

[0031] In some embodiments, a shock-absorbing device (not shown) is connected between the first suspension bracket and the cab, or between the first suspension bracket and the second suspension bracket. The shock-absorbing device is used to suppress the oscillations caused by the spring's rebound after absorbing shock and the impact from the road surface. It can accelerate the attenuation of vibrations between the vehicle frame and the cab, thereby improving the ride comfort of the vehicle. When driving over uneven roads, although the shock-absorbing spring can filter out road vibrations, the spring itself will still have reciprocating motion. The shock-absorbing device is used to suppress this spring bounce, thereby achieving a shock-absorbing effect. Specifically, the first mounting member 100 is provided with a shock absorber lug 111 for connecting the shock-absorbing device.

[0032] like Figure 2 , Figure 3 As shown, in some embodiments, the first mounting member 100 includes a first mounting bracket 110 disposed substantially along a first direction X, a second mounting bracket 120 disposed substantially along a second direction Y, and fasteners 310 connecting the first mounting bracket 110 and the second mounting bracket 120. The first mounting bracket 110 is provided with a first mounting portion 121 and a second mounting portion 122. Specifically, the first mounting bracket 110 is provided with a shock absorber lug 111 for connecting a shock absorption device, and the second mounting portion 122 protrudes from the body of the second mounting bracket 120.

[0033] like Figure 4As shown, in some embodiments, the second mounting member 200 includes a first side surface 201 and a second side surface 202 intersecting the first side surface 201. The first positioning portion 210 is disposed on the first side surface 201, and the second positioning portion 220 is disposed on the second side surface 202. Specifically, the first side surface 201 and the second side surface 202 are spatially intersecting, but there may be a gap between the first side surface 201 and the second side surface 202. Further, the first positioning portion 210 protrudes from the first side surface 201 and extends along a first direction X, and the second positioning portion 220 protrudes from the second side surface 202 and extends along a second direction Y.

[0034] Furthermore, the first side 201 and the second side 202 are perpendicular to each other, with the second side 202 facing the driver's cab. The first side 201 is perpendicular to the first direction X, and the second side 202 is perpendicular to the second direction Y. Specifically, the body of the second mounting member 200 is substantially rectangular, with its long side along the second direction Y. The first side 201 is part of a side with a larger area on this body.

[0035] In some embodiments, the first positioning part 210 includes at least a first positioning post 211 and a second positioning post 212 spaced apart. The first positioning post 211 and the second positioning post 212 protrude from the first side surface 201 and extend along the first direction X, and are spaced apart on the first side surface 201. The diameter of the first positioning post 211 is smaller than the diameter of the second positioning post 212, and the first assembly part 121 can be connected to the first positioning post 211 and the second positioning post 212 respectively. The different diameters of the first positioning post 211 and the second positioning post 212 allow for differentiation of the installation direction while aligning the first and second suspension brackets, enabling the installation process to limit the position in the first direction X and the second direction Y while also limiting other directions. Furthermore, the ends of the first positioning post 211 and the second positioning post 212 away from the first side surface 201 are arc-shaped to prevent damage to the first mounting member 100 during connection.

[0036] like Figure 5As shown, in some embodiments, the first assembly part 121 includes an abutment part 1211 and an abutment arm 1212. The first positioning post 211 abuts against the abutment part 1211, and the second positioning post 212 abuts against the abutment arm 1212. The abutment part 1211 and the abutment arm 1212 are respectively spaced apart on the second mounting bracket 120. Specifically, the second mounting bracket 120 has a first end extending between the first positioning post 211 and the second positioning post 212. The abutment part 1211 and the abutment arm 1212 are respectively provided on both sides of the first end at positions corresponding to the first positioning post 211 and the second positioning post 212. The abutment part 1211 is a sidewall with its first end facing the first positioning post 211, and the abutment arm 1212 is a hook-shaped structure protruding from the sidewall with its first end facing the second positioning post 212. The abutment arm 1212 has an abutment groove that abuts against the second positioning post 212 and is adapted to the outer peripheral shape of the second positioning post 212. The first mounting member 100 can be engaged with the second mounting member 200 in a defined position by the cooperation of the abutment part 1211, the abutment arm 1212, the first positioning post 211, and the second positioning post 212. Furthermore, the different diameters of the first positioning post 211 and the second positioning post 212 define the front-to-back sequence of the first mounting member 100. During installation, the abutment arm 1212 is first aligned with the second positioning post 212, which has a larger diameter and higher strength. Because the second positioning post 212 has a larger diameter and higher strength, it can first bear the load and align with the abutment groove. Then, the abutment part 1211 and the first positioning post 211 are aligned and abutted. By defining the sequence of positioning, installation can be completed more quickly.

[0037] In some embodiments, the first positioning part 210 includes at least three spaced positioning posts, at least one of which is located at a different position in the second direction Y from the other positioning posts. Specifically, the first positioning part 210 includes at least three positioning posts arranged in a triangular pattern. This triangular arrangement provides more stable support for the first mounting member 100 during installation, effectively distributing weight and pressure, reducing the load on a single positioning post, and thus providing more balanced support. Compared to the traditional linear arrangement, the triangular layout can distribute forces more evenly in different directions, preventing tilting or misalignment of the parts. Simultaneously, the stability of the triangular structure makes the overall assembly more robust, reducing the risk of loosening or deformation of parts. Furthermore, one of the at least three positioning posts has the largest diameter and serves as the first mounting post to be aligned with the assembly part during installation. This mounting post with the largest diameter can be located at a different height in the second direction Y from the other positioning posts.

[0038] In some embodiments, the second positioning part 220 is a third positioning post protruding from the second side 202 along the second direction Y. The diameters of the first positioning post 211 and the second positioning post 212 are the same, and the diameter of the third positioning post is larger than the diameter of the first positioning post 211. During installation, the second assembly part 122 is first aligned with the third positioning post with the larger diameter, and then the first assembly part 121 and the first positioning part 210 are connected. The position of the mounting part is first defined in one direction, and then installation in other directions is performed, which can complete the installation more quickly. Specifically, the second assembly part 122 is an assembly arm 1221 protruding from the second mounting bracket 120. The assembly arm 1221 has an assembly hole for connecting the third positioning post. During the installation of the mounting part, the assembly hole 1222 is fitted onto the third positioning post and moves along the direction defined by the third positioning post until the lower surface of the assembly arm 1221 abuts against the second surface, completing the connection between the second positioning part 220 and the second assembly part 122, thereby completing the positioning of the mounting parts in the second direction Y.

[0039] In some embodiments, the second mounting member 200 further includes a mounting surface 203 located between the first positioning portion 210 and the second positioning portion 220. The mounting surface 203 intersects the first direction X and the second direction Y, respectively. The first mounting member 100 has a connecting surface 101 parallel to the mounting surface 203. After the first mounting member 100 and the second mounting member 200 are connected, the mounting surface 203 abuts against the connecting surface 101. Specifically, the mounting surface 203 is located between the first side surface 201 and the second side surface 202, and is in contact with the first side surface 201 and the second side surface 202, respectively. Since the first side surface 201 and the second side surface 202 are perpendicular, the mounting surface 203 is inclined to the first side surface 201 and the second side surface 202, respectively. Further, the included angle between the mounting surface 203 and the first side surface 201 is 100-170°. Preferably, the included angle between the mounting surface 203 and the first side surface 201 can be 130°, 140°, 150°, or 160°. Correspondingly, the tilt angles of the connecting surface 101 and the mounting surface 203 are matched. By setting the tilted mounting surface 203, the first mounting part 100 and the second mounting part 200 are guided during the alignment process, greatly simplifying the complexity of the alignment operation. Through the tilted mounting surface 203, the positioning part can smoothly slide into the assembly part without deviation, thereby improving the accuracy and efficiency of installation. The tilted mounting surface 203 provides a clear guide and limit for the alignment of the positioning part and the assembly part. The tilt angle and shape of the mounting surface 203 can effectively constrain the movement direction of the positioning part, ensuring that it is aligned according to the predetermined trajectory during installation. This limiting function can ensure that the mounting parts are connected in the correct position and angle, further improving the accuracy and stability of the connection, accelerating the installation process, and improving the accuracy and reliability of the connection, providing a more optimized solution for the connection relationship between the cab and the frame.

[0040] Furthermore, in some embodiments, a guide rail (not shown in the figure) is provided on the mounting surface 203, and a guide groove (not shown in the figure) is correspondingly provided on the connecting surface 101 to slide in connection with the guide rail. By providing the guide rail and guide groove for guidance, the convenience and speed of connecting the first mounting member 100 and the second mounting member 200 can be further improved. A limiting member is provided at the end of the guide rail, which can restrict the first mounting member 100 from moving to a position where it can connect with the first positioning part 210.

[0041] Furthermore, in some embodiments, a wear-resistant layer is provided on the mounting surface 203. This wear-resistant layer is composed of a wear-resistant material with a certain degree of smoothness. The wear-resistant layer can be formed by coating a wear-resistant material onto a metal or metal alloy second mounting member 200; for example, the wear-resistant layer can be coated with polymers, metals, ceramics, etc. The wear-resistant layer can also be a polymer composite material, which has low density, good wear resistance, and chemical corrosion resistance; for example, reinforcing fibers (such as glass fiber, carbon fiber, etc.) and a polymer matrix. In some embodiments, the positioning post can be composed of a high-strength rigid material, such as steel, aluminum alloy, titanium alloy, and carbon fiber composite materials.

[0042] In some embodiments, the mounting device 1 further includes a fixing component 300 configured to connect the first mounting member 100 and the second mounting member 200. The fixing component 300 includes a first fixing hole 240 formed on the first mounting member 100, a second fixing hole 230 formed on the second mounting member 200, and a fastener 310. The fastener 310 passes through the first fixing hole 240 and the second fixing hole 230 respectively to connect the mounting member 100 and the second mounting member 200. In this embodiment, the fastener 310 includes a bolt and a nut. The bolt passes through the first fixing hole 240 and the second fixing hole 230 respectively, and the nut locks the protruding portion of the bolt to the first mounting member 100 or the second mounting member 200. Furthermore, there are multiple second fixing holes 230, at least one of which is located between the first positioning post 211 and the second positioning post 212 of the second mounting member 200, at least one of which is located between the first positioning part 210 and the second positioning part 220, and the first fixing hole 240 is provided on the first mounting member 100 at a position corresponding to all the second fixing holes 230.

[0043] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
