Description

Technical Field

[0001] This utility model relates to the field of automotive chassis tuning technology, specifically to an auxiliary support device for automotive chassis tuning. Background Technology

[0002] The automobile chassis, including the structural frame and load-bearing device, supports, mounts, and connects the various components and systems of the automobile. It is crucial to the stability, safety, and handling of the vehicle. Chassis tuning is an indispensable part of the automobile manufacturing process, involving fine-tuning of chassis parameters and suspension geometry, which directly affects the stability, handling, and comfort of the vehicle.

[0003] With the development of the automotive industry, the requirements for the precision and efficiency of automotive chassis tuning are becoming increasingly higher. Traditional automotive chassis support devices have gradually revealed some limitations during the tuning process. For example, some devices can only provide simple support and cannot meet the diverse requirements of different models, sizes, and center distribution needs.

[0004] Some auxiliary support devices are designed for specific vehicle models or chassis structures, resulting in a single structure that is difficult to apply to various types of vehicles. Their flexibility needs to be improved, and they lack multiple auxiliary support mechanisms. For example, the front of a typical chassis is relatively heavy, making it difficult to adjust the position of different support components effectively using the torque principle. If the support components on both sides of the chassis are mirror-symmetrical, the front of the chassis is prone to tilting downwards. Many traditional auxiliary support devices require manual adjustment, which is cumbersome, time-consuming, and inefficient. The stability and reliability of these devices need to be improved. Therefore, we propose an auxiliary support device for automotive chassis adjustment. Utility Model Content

Activating the hydraulic arms moves the main asynchronous motor and L-shaped frame to the outside of the chassis body, lifting the chassis body upwards via a support plate. By changing the position of the support plate on the chassis body, it can better adapt to different sizes and types of chassis bodies, improving applicability. Combined with the secondary asynchronous motor, secondary threaded rod, secondary threaded block, and first auxiliary hydraulic cylinder, it can form a clamping and fixing auxiliary support effect on the chassis body, thereby better supporting the chassis body during adjustment, improving efficiency, and enhancing the stability and reliability of the device.

By increasing friction, it can better clamp and support the chassis body while also better protecting the chassis body and preventing scratches and dents. When the second auxiliary hydraulic cylinder is activated, the rubber pressure plate clamps and fixes the chassis body from the side, thereby providing better auxiliary support.

[0032] Please see Figure 1 - Figure 6 This utility model provides a technical solution:

[0033] A chassis adjustment auxiliary support device for automobiles includes a conveying component 1, a chassis body 2 mounted on a sliding component of the conveying component 1, and a fixing frame 3 mounted on the outside of the conveying component 1. A rectangular cover 4 is hinged to the inside of the side wall of the fixing frame 3, allowing for easy inspection of the internal structure of the fixing frame 3 by opening the rectangular cover 4. A main asynchronous motor 5 is fixedly mounted on the top of the fixing frame 3, and a main threaded rod 6 is fixedly mounted on the output end of the main asynchronous motor 5. The main threaded rod 6 is rotatably mounted inside the fixing frame 3, and a main threaded block 7 is threaded onto the main threaded rod 6. The main threaded block 7 is slidably mounted on the fixing frame 3. Furthermore, two sets of rectangular covers 4, main asynchronous motors 5, main threaded rods 6, and main threaded blocks 7 are provided, and both sets are mirror images of each other at both ends of the chassis body 2 with the vertical centerline of the fixing frame 3 as the mirror axis, resulting in better support.

[0034] In one embodiment of this utility model, a support assembly 8 is provided on the fixing frame 3. The support assembly 8 includes a secondary asynchronous motor 81. The secondary asynchronous motor 81 is fixedly installed on the side wall of the main threaded block 7. A rotating shaft 82 is fixedly installed on the output end of the secondary asynchronous motor 81. The rotating shaft 82 is rotatably installed inside the main threaded block 7. The outer wall of the rotating shaft 82 is fixedly connected to the fixed end of the hydraulic arm 83. A main asynchronous motor 831 is fixedly installed on the outer wall of the piston end of the hydraulic arm 83. An L-shaped frame 84 is fixedly installed on the output shaft of the main asynchronous motor 831. The L-shaped frame 84 is rotatably installed on the piston end of the hydraulic arm 83. A secondary asynchronous motor 85 is fixedly installed on the outer wall of the L-shaped frame 84. A secondary threaded rod is fixedly installed on the output end of the secondary asynchronous motor 85. 86. The secondary threaded rod 86 is rotatably installed inside the L-shaped frame 84. The secondary threaded rod 86 is threaded with a secondary threaded block 87. The top of the secondary threaded block 87 is slidably installed inside the L-shaped frame 84. The bottom end of the secondary threaded block 87 is fixedly connected to the fixed end of the first auxiliary hydraulic cylinder 88. A support plate 89 is fixedly installed on the side wall of the piston end of the hydraulic arm 83. In addition, four sets of components are provided, including the secondary asynchronous motor 81, the rotating shaft 82, the hydraulic arm 83, the main asynchronous motor 831, the L-shaped frame 84, the secondary asynchronous motor 85, the secondary threaded rod 86, the secondary threaded block 87, the first auxiliary hydraulic cylinder 88, and the support plate 89, to improve the support effect. Furthermore, the support plate 89 is located below the first auxiliary hydraulic cylinder 88.

[0035] In this embodiment, the chassis body 2 is first transported to the location of the fixed frame 3 via the conveyor 1 (an existing device in the prior art, which will not be described in detail here), preparing for subsequent adjustment and support work. When the secondary asynchronous motor 81 is started, the secondary asynchronous motor 81 outputs power, driving the connected rotating shaft 82 to rotate. Since the fixed end of the hydraulic arm 83 is fixedly connected to the outer wall of the rotating shaft 82, the rotation of the rotating shaft 82 will allow multiple sets of hydraulic arms 83 to rotate to different angles, better targeting the chassis body 2 whose center of gravity is not located in the center. For example, the front of the chassis body 2 is generally heavier, and the control system will control the two sets of hydraulic arms 83 on both sides near the front end to extend their piston ends. The distance between the two sets of hydraulic arms 83 located further away from the front of the vehicle (i.e., the rear) is shorter. According to the torque calculation formula (M=F×L) (where M represents torque, F represents force, and L represents lever arm), when the force F is constant, the shorter the lever arm L, the smaller the torque M, resulting in better support during support. If the piston ends of the hydraulic arms 83 on both sides of the chassis body 2 extend by the same distance, forming a mirror symmetry, the front of the chassis body 2 is more likely to tilt downwards, thus achieving flexible adaptation of the chassis body 2 to different center of gravity distributions and ensuring the stability of the chassis body 2 during support. At the same time, the main asynchronous motor 831 and the L-shaped frame 84 will move synchronously to the outside of the chassis body 2, hydraulic... The piston end of the pressure arm 83 pushes the support plate 89 to move until the support plate 89 reaches the bottom of the chassis body 2, preparing for the subsequent lifting of the chassis body 2. Once the support plate 89 is in place, the main asynchronous motor 5 is started, driving the main threaded rod 6 to rotate. The rotation of the main threaded rod 6 causes the main threaded block 7 to move upward along the fixed frame 3. As the main threaded block 7 rises, the support plate 89 moves upward synchronously, lifting the chassis body 2. During this process, the position of the support plate 89 on the chassis body 2 can be changed according to the size, type, and center of gravity distribution of the chassis body 2 by adjusting the angle of the hydraulic arm 83 beforehand, thus better adapting to various chassis bodies 2. This improves the applicability of the support device. When auxiliary support is needed to clamp and fix the top of the chassis body 2, the main asynchronous motor 831 is started, causing the L-shaped frame 84 to rotate and adjust its position. At the same time, the secondary asynchronous motor 85 is started, driving the secondary threaded rod 86 to rotate, which in turn causes the secondary threaded block 87 to move laterally inside the L-shaped frame 84. The movement of the secondary threaded block 87 will drive the first auxiliary hydraulic cylinder 88 to move laterally in sync, thereby flexibly adjusting the position of the first auxiliary hydraulic cylinder 88. Finally, the first auxiliary hydraulic cylinder 88 is started to achieve a stable clamping and fixing auxiliary support effect on the top of the chassis body 2, thereby improving efficiency and enhancing the stability and reliability of the device.

[0036] In one embodiment of this utility model, an auxiliary component 9 is provided on the outside of the chassis body 2. The auxiliary component 9 includes a rubber pad 91. The rubber pad 91 is fixedly installed on the top of the support plate 89. The rubber pad 91 fits against the bottom of the chassis body 2, resulting in better support. In addition, a rubber pressure block 92 is fixedly installed at the bottom of the piston end of the first auxiliary hydraulic cylinder 88. The rubber pressure block 92 fits against the top of the chassis body 2, resulting in better support. In addition, the outer wall of the main threaded block 7 is fixedly connected to the fixed end of the second auxiliary hydraulic cylinder 93. A rubber pressure plate 94 is fixedly installed on the piston end of the second auxiliary hydraulic cylinder 93. The rubber pressure plate 94 fits against the side wall of the chassis body 2. In addition, there are two sets of the second auxiliary hydraulic cylinder 93 and the rubber pressure plate 94, which results in better support. Furthermore, the rubber pad 91, the rubber pressure block 92, and the rubber pressure plate 94 are all made of rubber, which better protects the chassis body 2 and prevents scratches and dents.

[0037] In this embodiment, the rubber pad 91 fixedly installed on the top of the support plate 89 will fit tightly against the bottom of the chassis body 2, providing support. At the same time, the rubber material can effectively prevent scratches on the chassis body 2. When the first auxiliary hydraulic cylinder 88 is activated, the rubber pressure block 92 fixedly installed at the bottom of the piston end of the first auxiliary hydraulic cylinder 88 will move downward and fit tightly against the top of the chassis body 2, clamping and fixing the chassis body 2 to prevent it from shaking during the adjustment process. In addition, when the second auxiliary hydraulic cylinder 93 is activated, the rubber pressure plate 94 fixedly installed at its piston end will move towards the side wall of the chassis body 2 until it fits tightly against the side wall of the chassis body 2. The rubber pressure plate 94, rubber pad 91, and rubber pressure block 92 work together to not only increase the friction between the rubber and the chassis body 2 and achieve a better clamping and support effect, but also protect the chassis body 2 in all directions, avoiding scratches and dents during the adjustment process, and ensuring the integrity and safety of the chassis body 2 during the adjustment process.

[0038] All electrical components appearing in this application are electrically connected to the control system and 220V AC mains power. The control system is a conventional and known device capable of controlling the conveyor 1, the main asynchronous motor 5, the secondary asynchronous motor 81, the hydraulic arm 83, the main asynchronous motor 831, the secondary asynchronous motor 85, the first auxiliary hydraulic cylinder 88, and the second auxiliary hydraulic cylinder 93. All standard parts used in this application can be purchased from the market.

The machinery, parts, and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
