Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to an assembly alignment structure for automotive shock absorbers. Background Technology

[0002] With the rapid development of new energy vehicles in my country, higher requirements are being placed on the ride comfort and handling stability of these vehicles. Shock absorbers are now very common. In general, during the chassis assembly process of A0-class vehicles, the shock absorber is the first component to come into contact with the vehicle body. When assembling the chassis and the vehicle body, the shock absorber needs to be installed on the vehicle bracket. During the installation process, due to manufacturing and assembly errors, the mounting holes on the shock absorber and the assembly holes on the vehicle bracket often cannot be aligned smoothly. This requires repeated manual correction to make the mounting holes and assembly holes align, which affects production efficiency.

[0003] In the existing technology, the alignment of shock absorbers and body brackets is generally done using external assembly tools. After the external assembly tools are used, they still need to be removed manually, which increases the workload and affects production efficiency. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an assembly and alignment structure for automotive shock absorbers, which aims to solve the problem that in the existing technology, external assembly tools still need to be manually removed after use, which still increases the workload and affects production efficiency.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A vehicle shock absorber assembly alignment structure includes a shock absorber assembly for connecting to a vehicle body bracket. The shock absorber assembly includes a shock absorber and a top post. One end of the shock absorber is connected to the top post. A base plate is provided on the side of the shock absorber facing the top post. A positioning post and several limiting posts are provided on the side of the base plate facing away from the shock absorber. A mounting hole is provided on the side of the top post facing the base plate, and the mounting hole matches the positioning post. Several positioning grooves are provided on the outer wall of the top post, and the positioning grooves match the limiting posts. The vehicle body bracket includes a mounting part. One side of the mounting part is recessed to form a receiving cavity. A through hole is provided in the receiving cavity. Several positioning rods are provided on the side wall of the receiving cavity, and the positioning rods match the positioning grooves. The base plate is connected to the vehicle body bracket through a metal connector.

[0007] Furthermore, the top column includes an upper body and a lower body. One end of the lower body is connected to the upper body, and the other end is connected to the shock absorber. The upper body and the lower body are coaxially connected. The mounting hole and the positioning groove are both provided on the lower body.

[0008] Furthermore, an acute angle is formed between the side wall of the upper part of the top column and the side of the upper part of the top column facing the lower part of the top column.

[0009] Furthermore, the upper part of the top column and the lower part of the top column are integrally formed.

[0010] Furthermore, an obtuse angle is formed between the sidewall of the receiving cavity and the bottom of the receiving cavity.

[0011] Furthermore, the total length of the limiting post and the positioning rod is less than the length of the positioning groove.

[0012] Furthermore, the shock absorber assembly also includes a top mount, the side of the base plate facing away from the shock absorber is connected to the top mount, and the side of the top mount facing away from the base plate is connected to the mounting portion.

[0013] Furthermore, a base plate connection hole is provided on the base plate, a top adhesive connection hole is provided on the top adhesive, and a body bracket connection hole is provided on the mounting part. The base plate connection hole, the top adhesive connection hole, and the body bracket connection hole are all adapted to the metal connector.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by connecting the top column to the positioning column on the bottom plate of the shock absorber, and by matching the positioning groove on the top column with the limiting rod on the bottom plate, and by matching the positioning rod on the inner wall of the receiving cavity with the positioning groove on the top column, the top column is limited. When the shock absorber assembly passes through the through hole of the receiving cavity and connects to the body bracket, the alignment work between the shock absorber and the body bracket installation position is completed without repeated manual correction, thus avoiding shaking or tilting during installation. When the shock absorber assembly and the body bracket are assembled through the metal connector, the top column does not need to be removed to start subsequent work, reducing workload and improving assembly efficiency.

[0027] Please see Figures 1 to 6 This utility model proposes a vehicle shock absorber assembly alignment structure, including a shock absorber assembly 1 for connecting to a vehicle body bracket 2. The shock absorber assembly 1 includes a shock absorber 10 and a top post 11. One end of the shock absorber 10 is connected to the top post 11. A base plate 102 is provided on the side of the shock absorber 10 facing the top post 11. A positioning post 101 and several limiting posts 106 are provided on the side of the base plate 102 facing away from the shock absorber 10. Mounting holes 113 are provided on the side of the top post 11 facing the base plate 102. The mounting hole 113 matches the positioning post 101. The outer wall of the top post 11 is provided with several positioning grooves 114, which match the limiting post 106. The vehicle body bracket 2 includes a mounting part 24. One side of the mounting part 24 is recessed to form a receiving cavity 20. The receiving cavity 20 is provided with a through hole penetrating the mounting part 24. Several positioning rods 22 are provided on the side wall of the receiving cavity 20. The positioning rods 22 match the positioning grooves 114. The base plate 102 is connected to the vehicle body bracket 2 through a metal connector 3.

[0028] The top column 11 includes an upper top column body 111 and a lower top column body 112. One end of the lower top column body 112 is connected to the upper top column body 111, and the other end of the lower top column body 112 is connected to the shock absorber 10. The upper top column body 111 and the lower top column body 112 are coaxially connected. The mounting hole 113 and the positioning groove 114 are both provided on the lower top column body 112.

[0029] The side wall of the upper part of the top column 111 and the side of the upper part of the top column 111 facing the lower part of the top column 112 form an acute angle. Preferably, the upper part of the top column 111 can be conical and the lower part of the top column 112 can be cylindrical.

[0030] The upper body 111 and the lower body 112 of the top column are integrally formed. The advantage of integral forming is that when the top column 11 is placed in the receiving cavity 20, it will not shake or tilt due to the unstable connection between the upper body 111 and the lower body 112 of the top column.

[0031] The side wall of the receiving cavity 20 forms an obtuse angle with the bottom of the receiving cavity 20, which makes it easier for the shock absorber assembly 1 to be placed. When the top column 11 touches the side wall of the receiving cavity 20, the tilt of the side wall of the receiving cavity 20 and the structure of the top column upper body 111 can better guide the top column 11 to the position of the through hole, reducing the difficulty of docking.

[0032] The top post 11 is made of ABS, PET or PBT. These materials have certain rigidity, toughness and high temperature and corrosion resistance. When the positioning groove 114, the limiting post 106 and the positioning rod 22 are in action, they will not shake or tilt due to the material being too soft.

[0033] The total length of the limiting post 106 and the positioning rod 22 is less than the length of the positioning groove 114.

[0034] The shock absorber assembly 1 also includes a top adhesive 104, which is disposed on the side of the base plate 102 facing away from the shock absorber 10. The top adhesive 104 is connected to the base plate 102, and the side of the top adhesive 104 facing away from the base plate 102 is connected to the mounting part 24.

[0035] The top rubber 104 is made of rubber. When the shock absorber 10 is working while the vehicle is in motion, the top rubber 104 bears the severe impact of the wheel on the vehicle body. It dissipates energy through viscoelasticity to maintain the stability of the vehicle body, while avoiding direct collision between the shock absorber 10 and the metal parts of the vehicle body bracket 2. This increases the service life of the shock absorber 10 and reduces abnormal noises during vehicle operation.

[0036] The base plate 102 has a base plate connection hole 103, the top adhesive 104 has a top adhesive connection hole 105, and the body bracket 2 has a body bracket connection hole 23. The base plate connection hole 103, the top adhesive connection hole 105, and the body bracket connection hole 23 are all adapted to the metal connector 3.

[0037] Specifically, during the assembly process, firstly, align the mounting hole 113 on the lower body 112 of the top column 11 with the positioning post 101 on the base plate 102, and simultaneously align the positioning groove 114 on the lower body 112 of the top column with the limiting post 106 on the base plate 102 to complete the installation of the top column 11. Then, install the top adhesive 104 on the base plate 102. Since the top adhesive 104 wraps around the outside of the base plate 102, it provides good protection for the limiting post 106 on the base plate 102 and the top column 11 installed on the base plate 102.

[0038] Then, during the process of placing the shock absorber assembly 1 into the receiving cavity 20 of the body bracket 2, the positioning groove 114 on the lower body 112 of the top pillar matches the positioning rod 22 in the receiving cavity 20. Since the positioning rod 22 and the limiting post 106 simultaneously contact the positioning groove 114 on the lower body 112 of the top pillar, they play a limiting role. Since the bottom plate connecting hole 103 on the bottom plate 102, the top rubber connecting hole 105 on the top rubber 104, and the body bracket connecting hole 23 on the mounting part 24 match, the alignment is completed at the same time as the shock absorber assembly 1 and the body bracket 2 are connected. There is no need for repeated manual correction and alignment, which also reduces the shaking or tilting during the installation process and ensures the stability of the installation process.

[0039] Finally, since the top pillar 11 is made of ABS, PET or PBT material, it has high rigidity, good toughness, and is also resistant to high temperature and corrosion. After the shock absorber assembly 1 and the body bracket 2 are installed, as part of the shock absorber assembly 1, no additional disassembly is required to start subsequent work, which reduces the workload and improves the assembly efficiency.
