Description

Technical Field

[0001] This utility model relates to the field of automotive technology, specifically to a subframe assembly with an auxiliary mounting structure. Background Technology

[0002] The subframe of a car is an important component of the car chassis system, used to connect the suspension system and the body. During the car's operation, the suspension system will cause various impacts to the body. After the subframe absorbs the impact of the suspension system, it will transfer the load force to the body. The load force is reduced after being transferred through the subframe, which can reduce the impact on the body.

[0003] According to the publicly disclosed subframe mounting structure and vehicle (Announcement No.: CN112158258B), the above application includes a mounting body and a mounting sleeve. The mounting body has a cavity, and the mounting sleeve penetrates through two opposite sides of the mounting body and through the cavity of the mounting body. The mounting sleeve is fixedly connected to the mounting body and has a mounting hole. One end of the mounting sleeve has an annular protrusion, which is fixedly connected to the mounting body.

[0004] However, in actual use and installation, the subframe mentioned above needs to be corrected during installation to ensure symmetry with the vehicle body and avoid errors in geometric parameters such as toe-in, caster, and camber. This requires repeated checks to ensure installation accuracy. In view of this, we propose a subframe assembly with an auxiliary installation structure. Utility Model Content

[0005] The purpose of this utility model is to provide a subframe assembly with an auxiliary installation structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a subframe assembly with an auxiliary mounting structure, comprising a subframe body, wherein an auxiliary mounting component is provided on the outer wall of the subframe body, the auxiliary mounting component comprising:

[0007] A limiting strip, wherein an insertion block is fixedly connected to the side of the limiting strip away from the subframe body;

[0008] The mounting plate has a rotating shaft rotatably connected to its top. A limit post is fixedly connected to the outer wall of the rotating shaft. One end of the rotating shaft has a hexagonal groove, and the other end of the rotating shaft is threaded with a bolt.

[0009] An adjustment handle is provided, with a hexagonal prism fixedly connected to its end face.

[0010] Preferably, the limiting strip is fixedly connected to the side wall of the subframe body, and the insertion block is arranged in an isosceles trapezoid with an upper base and a lower base, the upper base being located on the side close to the subframe body.

[0011] Preferably, the mounting plate is fixedly connected to the top end face of the subframe body, and a mounting seat is fixedly connected to the top of the mounting plate, the mounting seat being sleeved with the rotating shaft.

[0012] Preferably, the axis of the rotating shaft does not coincide with the axis of the limiting post, the bolt is provided with a threaded section and a nut, the nut abuts against the side wall of the mounting base, and rotating the bolt fixes the rotating shaft and the limiting post, thereby increasing the connection points between the subframe body and the main frame.

[0013] Preferably, the hexagonal slot is inserted into the hexagonal prism, and the angle between the axis of the adjusting handle and the axis of the hexagonal prism is 30 degrees. Rotating the adjusting handle and the hexagonal prism drives the rotating shaft and the limiting post to rotate, so that the limiting post clamps the main frame between the limiting post and the limiting strip.

[0014] Preferably, there are two sets of mounting plates, rotating shafts and limiting posts, and the two sets of mounting plates, rotating shafts and limiting posts are set on the top end face of the subframe body.

[0015] Preferably, the side wall of the limiting post is fixedly connected with a rubber strip, and the number of rubber strips is set in several groups, with the several groups of rubber strips evenly spaced on the outer wall of the limiting post.

[0016] Compared with the prior art, the present invention provides a subframe assembly with an auxiliary mounting structure, which has the following advantages:

[0017] 1. This subframe assembly with an auxiliary installation structure guides the subframe body through the auxiliary installation components and insert blocks, automatically guiding it into position, reducing manual adjustments, improving assembly efficiency, and ensuring that the limiting post abuts against the main frame, thereby restricting the main frame between the limiting post and the limiting strip. This achieves initial positioning of the main frame and subframe body, forming a reliable initial positioning system, significantly reducing the risks of displacement, shaking, and stress concentration. Before the screws and nuts are tightened, the subframe body already has basic fixing force. Turning the bolts locks the pivot and the limiting post, making the connection between the subframe body and the main frame more robust and stable. This increases the number of connection points between the subframe body and the main frame, distributes the structural load, reduces stress concentration at each connection point, and enhances the overall shear and tensile resistance.

[0018] 2. The subframe assembly with auxiliary installation structure has a lower coefficient of friction between exposed metal and a higher coefficient of friction between rubber and metal through the rubber strip. When the limiting post rotates and presses against the main frame, the rubber strip provides stronger friction to prevent loosening or displacement due to vibration or impact, thus achieving a more stable initial positioning of the subframe.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a subframe assembly with an auxiliary installation structure, including a subframe body 1, and an auxiliary installation component 2 provided on the outer wall of the subframe body 1. The auxiliary installation component 2 includes a limit bar 201, an insertion block 202, a mounting plate 203, a rotating shaft 204, a limit post 205, a hexagonal groove 206, a hexagonal prism 207, an adjustment handle 208, and a bolt 209.

[0026] In one embodiment of this utility model, an insertion block 202 is fixedly connected to the side of the limiting strip 201 away from the subframe body 1. The limiting strip 201 is fixedly connected to the side wall of the subframe body 1. The insertion block 202 is arranged in an isosceles trapezoidal shape, with an upper base and a lower base. The upper base is located on the side close to the subframe body 1.

[0027] The top of the mounting plate 203 is rotatably connected to a rotating shaft 204. The mounting plate 203 is fixedly connected to the top end face of the subframe body 1. The top of the mounting plate 203 is fixedly connected to a mounting seat, which is sleeved with the rotating shaft 204. A limit post 205 is fixedly connected to the outer wall of the rotating shaft 204. One end of the rotating shaft 204 is provided with a hexagonal groove 206, and the other end of the rotating shaft 204 is threadedly connected to a bolt 209. The axis of the rotating shaft 204 does not coincide with the axis of the limit post 205. The bolt 209 is provided with a threaded section and a nut. The nut abuts against the side wall of the mounting seat. Rotating the bolt 209 fixes the rotating shaft 204 and the limit post 205, increasing the connection points between the subframe body 1 and the main frame. There are two sets of mounting plates 203, rotating shafts 204, and limit posts 205. The two sets of mounting plates 203, rotating shafts 204, and limit posts 205 are located on the top end face of the subframe body 1.

[0028] A hexagonal prism 207 is fixedly connected to the end face of the adjusting handle 208. The hexagonal slot 206 is inserted into the hexagonal prism 207. The angle between the axis of the adjusting handle 208 and the axis of the hexagonal prism 207 is 30 degrees. Rotating the adjusting handle 208 and the hexagonal prism 207 drives the rotating shaft 204 and the limiting post 205 to rotate, so that the limiting post 205 clamps the main frame between the limiting post 205 and the limiting strip 201.

[0029] The main frame is aligned with the insertion block 202 and inserted, so that the insertion block 202 is inserted into the main frame. The isosceles trapezoidal insertion block 202 guides the subframe body 1. Even if there is a certain initial positional deviation between the main frame and the insertion block 202, the deviation can be gradually corrected, automatically guiding it into place, reducing manual adjustment and improving assembly efficiency. Then, the adjusting handle 208 is rotated to rotate the limiting post 205. The limiting post 205 abuts against the main frame, thereby restricting the main frame between the limiting post 205 and the limiting strip 201, realizing the initial alignment of the main frame and the subframe body 1. The main frame and the subframe body 1 are fixed by the connecting screw and nut. After rotation, the limiting post 205 presses tightly between the main frame and the limiting strip 201 to form a clamping force, forming a reliable initial positioning system, which greatly reduces the hidden dangers of displacement, shaking, stress concentration and other problems. Before the screw and nut are tightened, the subframe body 1 has a basic fixing force. The design of the hexagonal prism 207 and hexagonal slot 206 allows the adjustment handle 208 to be quickly inserted and removed. After the subframe body 1 is installed, the adjustment handle 208 can be removed to reduce the protrusions on the subframe body 1.

[0030] After removing the adjustment handle 208, rotate the bolt 209 to fix the rotating shaft 204 and the limiting post 205. The rotating shaft 204 and the limiting post 205 are locked, which makes the subframe body 1 and the main frame more robust and stable. This increases the number of connection points between the subframe body 1 and the main frame, distributes the structural load, reduces stress concentration at each connection point, and enhances the overall shear and tensile resistance.

[0031] In addition, rubber strips 3 are fixedly connected to the side wall of the limiting post 205. Several sets of rubber strips 3 are set at equal intervals on the outer wall of the limiting post 205. The friction coefficient between exposed metal is low, while the friction coefficient between rubber and metal is higher. When the limiting post 205 rotates to press the main frame, the rubber strips 3 provide stronger friction to prevent loosening or displacement due to vibration or impact, thus achieving a more stable initial positioning of the subframe. The metal limiting post 205 is prone to hard contact, impact, and scratches when it comes into direct contact with the metal main frame. The addition of rubber strips 3 forms a flexible buffer pad, so even if the alignment deviation is slightly large or the operation is improper during installation, the main frame will not be damaged.

[0032] In this utility model, during use, the main frame is aligned with the insertion block 202 and inserted, so that the insertion block 202 is inserted into the main frame. The insertion block 202 guides the subframe body 1, automatically guiding it into place and reducing manual adjustment. Rotating the adjustment handle 208 causes the limiting post 205 to abut against the main frame, restricting the main frame between the limiting post 205 and the limiting strip 201, achieving initial positioning of the main frame and the subframe body 1, forming a clamping force, and forming a reliable initial positioning system. Before the screw and nut are tightened, the subframe body 1 already has basic fixing force. Rotating the bolt 209 further fixes the rotating shaft 204 and the limiting post 205, locking the rotating shaft 204 and the limiting post 205, so that a more solid and stable connection is formed between the subframe body 1 and the main frame, increasing the number of connection points between the subframe body 1 and the main frame and distributing the structural load.

[0033] 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.
