Description

Technical Field

[0001] This invention belongs to the field of automotive suspension, specifically, it relates to a suspension double-ear connection structure positioning device and its assembly method. Background Technology

[0002] The double-ear connection structure in automotive suspension typically refers to a specific suspension design. This structure includes two female and two male ear-shaped connection points that interlock to connect and support suspension components. The double-ear design usually involves two ear-shaped connection points that provide better support and stability, reducing suspension sway and deformation during driving, thereby improving vehicle handling. The double-ear design also allows for more even distribution of load on the suspension, reducing localized wear and fatigue, and extending suspension lifespan. In some suspension systems, the double-ear design offers a wider adjustment range, allowing for more precise adjustments to suspension height and stiffness to adapt to different driving conditions and needs. The double-ear structure can work in conjunction with other suspension components (such as shock absorbers and springs) to optimize vehicle damping and improve ride comfort. In summary, the double-ear design plays a crucial role in automotive suspension systems, contributing to improved overall vehicle performance and safety.

[0003] In existing technologies, the assembly of the double-ear connection structure is usually achieved by manual positioning, which makes it difficult to guarantee assembly accuracy. During the assembly process, it is necessary to ensure the precise alignment between the female and male ends of the double-ear connection to avoid unnecessary stress concentration or deviation after assembly, and to avoid affecting the suspension performance and vehicle stability due to assembly errors. In addition, the double-ear connection structure needs to withstand a large load, which requires the material of the double-ear connection structure to have sufficient strength and toughness. It is inconvenient to handle during manual positioning, resulting in low positioning and assembly efficiency, and making it difficult to guarantee the consistency and quality of the double-ear connection structure.

Detailed Implementation

[0031] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0032] Figure 1 This is a schematic diagram of the suspension double-ear connection structure positioning device in an embodiment of the present invention; Figure 2 This is an exploded view of the suspension double-ear connection structure positioning device in an embodiment of the present invention; Figure 3 This is a schematic diagram of the dual-ear connection structure in an embodiment of the present invention.

[0033] like Figure 1 , Figure 2 as well as Figure 3 As shown, the suspension dual-ear connection structure positioning device provided by the present invention includes a driving assembly 10 and a positioning assembly 20 connected to the driving assembly 10, such as... Figure 3 As shown, the double-ear connection structure 1 includes a double-ear female end 2 and a double-ear male end 3. The positioning component 20 includes a positioning seat 21, which is disposed on both sides of the double-ear female end 2. The positioning seat 21 is provided with a guide block 22, which is located on both sides of the double-ear male end 3. The positioning component 21 and the guide block 22 can facilitate the assembly and positioning of the double-ear female end 2 and the double-ear male end 3. The positioning seat 21 can be flexibly adjusted according to the size and assembly tolerance of the double-ear connection structure 1, which effectively ensures the precise alignment between the double-ear female end 2 and the double-ear male end 3, avoids unnecessary stress concentration, and effectively avoids the problem of affecting the suspension performance and vehicle stability due to assembly errors.

[0034] like Figure 1 and Figure 2 As shown, the drive assembly 10 includes a drive cylinder 11 and a crossbeam 12. The drive cylinder 11 includes a cylinder body 111 and a piston rod 112. The cylinder body 11 is mounted on the double-ear splicing device. One end of the piston rod 112 is movably mounted inside the cylinder body 111, and the other end of the piston rod 111 is connected to the crossbeam 12. The piston rod 111 is arranged vertically, so that the drive cylinder 11 can drive the crossbeam 12 to move up and down in the vertical direction. The crossbeam 12 provides an installation position for the positioning assembly 20, so that the crossbeam 12 can drive the positioning assembly 20 to move up and down. This facilitates the positioning assembly 20 to assemble and position the double-ear connection structure 1, effectively ensuring the precise alignment between the double-ear female end 2 and the double-ear male end 3, avoiding unnecessary stress concentration, and effectively avoiding the problem of the suspension performance and vehicle stability being affected by assembly errors.

[0035] The positioning component 20 also includes a mounting base 23, which has a mounting groove 231 adapted to the crossbeam 12. The mounting base 23 is fitted onto the crossbeam 12 through the mounting groove 231. The crossbeam 12 is cuboid in shape. The mounting groove 231 is adapted to the crossbeam 12 and is a cuboid through groove, which allows the mounting base 23 to be movably mounted on the crossbeam 12 along its length. The two mounting bases 23 are respectively located at both ends of the crossbeam 12. The mounting bases 23 are connected to the positioning base 21, which facilitates flexible adjustment according to the size and assembly tolerance of the double-ear connection structure 1. This effectively ensures the precise alignment between the double-ear female end 2 and the double-ear male end 3, avoids unnecessary stress concentration, and effectively avoids the problem of the suspension performance and vehicle stability being affected by assembly errors.

[0036] The mounting base 23 is provided with a first locking hole 232, and a first locking screw 233 is inserted into the first locking hole 232. The first locking screw 233 is screwed into the first locking hole 232, and the end of the first locking screw 233 abuts against the surface of the crossbeam 12, thereby locking the mounting base 23 onto the crossbeam 12. This can prevent the mounting base 23 from shaking or moving during the precise positioning process, which would interfere with the precise alignment between the double-ear female end 2 and the double-ear male end 3, thus improving the reliability of the structure.

[0037] A connecting rod 24 is provided between the positioning seat 23 and the mounting seat 21. One end of the connecting rod 24 is connected to the positioning seat 21, and the other end of the connecting rod 24 is connected to the mounting seat 23, thereby connecting the positioning seat 23 and the mounting seat 21. The mounting seats 21 at both ends of the crossbeam 12 are respectively connected to the positioning seats 23. The two positioning seats 23 are located on both sides of the double-ear end 2. The connecting rod 24 can provide a certain operating space between the positioning seat 23 and the mounting seat 21, which facilitates the operator to perform assembly operations and improves the reliability of the structure.

[0038] Figure 4 This is a schematic diagram of the installation of the rotating shaft and rollers in an embodiment of the present invention. Figure 1 ; Figure 5 This is a schematic diagram of the installation of the rotating shaft and rollers in an embodiment of the present invention. Figure 2 .

[0039] like Figure 4 and Figure 5As shown, the positioning seat 21 is provided with a roller groove 211, and the inner wall of the roller groove 211 is provided with a shaft groove 212. A shaft 213 passes through the shaft groove 212, and a roller 214 is sleeved on the shaft 213. The two shaft grooves 212 are located on both sides of the roller groove 211, and the two ends of the shaft 213 are movably set in the shaft grooves 212. The shaft grooves 212 are in the shape of a square and a semicircle, so that the ends of the shaft 213 can be movably set in the shaft grooves 212. The roller 214 is connected to the roller groove. The roller 214 is rotatably mounted on the rotating shaft 213 and abuts against the double-ear female end 2. The two rollers 214 on the positioning seats 21 on both sides of the double-ear female end 2 abut against the two sides of the double-ear female end 2, thereby limiting the double-ear female end 2 and ensuring the stability of the double-ear female end 2 during the positioning process. This effectively ensures the precise alignment between the double-ear female end 2 and the double-ear male end 3, avoids unnecessary stress concentration, and effectively avoids the problem of the suspension performance and vehicle stability being affected by assembly errors.

Figure 1 ; Figure 7 This is a schematic diagram of the installation of the compression spring and preload screw in an embodiment of the present invention. Figure 2 ; Figure 8 This is a schematic diagram of the connection between the positioning seat and the double-eared female end in an embodiment of the present invention. Figure 1 ; Figure 9 This is a schematic diagram of the connection between the positioning seat and the double-eared female end in an embodiment of the present invention. Figure 2 .

[0041] like Figure 6 and Figure 7 As shown, the positioning seat 21 is also provided with a spring groove 215, which communicates with the shaft groove 212. A compression spring 216 is provided in the spring groove 215. One end of the compression spring 216 passes through the shaft groove 212 and is connected to the shaft 213. The end of the spring groove 215 away from the shaft groove 212 is provided with an internal thread. A preload screw 217 is screwed onto the end of the spring groove 215 away from the shaft groove. The preload screw 217 is connected to the end of the compression spring 216 away from the shaft 213. Figure 8 and Figure 9As shown, the compression spring 216 is in a compressed state, which can press the roller 214 onto the double-ear female end 2. The double-ear female end 2 is provided with positioning holes 4, which are located on both sides of the double-ear female end 2. The crossbeam 12 drives the positioning seat 21 to move up and down in the vertical direction. The roller 214 moves up and down on the surface of the double-ear female end 2. When the roller 214 moves downward, the roller 214 is locked in the positioning hole 4. The compression spring 216 presses the roller 214 into the positioning hole 4. The rollers 214 of the positioning seats 21 on both sides clamp and fix the double-ear female end 2, thereby limiting the double-ear female end 2 and ensuring the stability of the double-ear female end 2 during the positioning process. This effectively ensures the precise alignment between the double-ear female end 2 and the double-ear male end 3, avoids unnecessary stress concentration, and effectively avoids the problem of the suspension performance and vehicle stability being affected by assembly errors.

[0042] Figure 10 This is a schematic diagram of the installation of the guide block in an embodiment of the present invention. Figure 1 ; Figure 11 This is a schematic diagram of the installation of the guide block in an embodiment of the present invention. Figure 2 .

[0043] like Figure 10 and Figure 11 As shown, a slide rail 25 is provided on the side of the positioning seat 21 near the male end 3 of the double ear, and a groove 221 adapted to the slide rail 25 is provided on the guide block 22. The guide block 22 can be slidably set on the slide rail 25 through the groove 221. The two guide blocks 22 on the two positioning seats 21 can be adjusted according to the size of the male end 3 of the double ear. A ramp is provided on the side of the guide blocks 22 that is close to each other for guiding the male end 3 of the double ear. After the female end 2 of the double ear is fixed by the positioning seat 21, the double ear splicing device pushes the male end 3 of the double ear towards the female end 2 of the double ear. Guided by the guide block 22, it reaches the assembly position, thereby effectively ensuring the precise alignment between the female end 2 of the double ear and the male end 3 of the double ear, avoiding unnecessary stress concentration, and effectively avoiding the problem of affecting the performance of the suspension and the stability of the vehicle due to assembly errors.

[0044] The guide block 22 is provided with a second locking hole 222, and a second locking screw 223 is inserted into the second locking hole 222. The slide rail 25 is provided with a fixing hole that matches the second locking screw 223. The fixing holes are evenly distributed on the slide rail 25. After adjusting the distance between the guide blocks 22 according to the size of the male end 3 of the double ears and the assembly tolerance, the second locking screw 223 is inserted into the second locking hole 222 and the fixing hole to fix the guide block 22 on the positioning seat 21, so as to prevent the guide block 22 from shaking or moving during the assembly process.

[0045] The present invention also provides an assembly method for a suspension double-ear connection structure positioning device, used for assembling the above-mentioned suspension double-ear connection structure positioning device, comprising the following steps:

[0046] Step S1: Connect the mounting base 23 to the crossbeam 12 of the drive assembly 10, and fit the mounting base 23 onto the crossbeam 12 through the mounting groove 231, so that the mounting base 23 can be movably mounted on the crossbeam 12 along the length direction of the crossbeam 12.

[0047] Step S2: Adjust the position of the positioning seat 21. Make flexible adjustments according to the size and assembly tolerance of the double ear connection structure 1 to ensure that the assembly tolerance between the double ear female end 2 and the double ear male end 3 and the distance between the two mounting seats 23 are compatible.

[0048] Step S3: Install the guide block 22 on the positioning seat 21 and adjust the position of the guide block 22 to match the male end of the double ear.
