[0002] Currently, for non-load-bearing vehicles, the body and frame are connected via body mounts. Bolting and assembly typically requires two workers simultaneously: one tightens the bolt flange with a tool to prevent rotation while the other tightens the mating nut. This results in significant labor and time costs. Furthermore, in confined locations, it's difficult for one person to perform anti-rotation tightening.

[0003] A Chinese patent with publication number "CN217554040U" discloses a vehicle body suspension installation structure and a vehicle, including a vehicle body and a suspension. The suspension is fixed to the vehicle body by bolts, and a limit stop arm is formed on the bolt. A limit protrusion is provided on the vehicle body to block the limit stop arm to prevent the bolt from rotating during assembly.

[0004] During later use, the device also has the following problems: the limiting protrusion has a poor limiting effect on the bolt, and the contact between the limiting protrusion and the limiting arm is point contact, which not only causes damage to the bolt structure during the limiting process, but the limiting arm is also easily lifted up under the squeezing of the limiting protrusion and breaks away from the limit of the limiting protrusion.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] The directional terms used in the detailed description are intended solely to facilitate understanding of the technical solutions described herein by those skilled in the art based on the visual orientation shown in the accompanying drawings. Unless otherwise specified or limited, the terms "dispose," "install," and "connect" are to be interpreted broadly, and those skilled in the art will understand their specific meanings in this utility model based on the specific circumstances.

[0026] like Figure 1 As shown, a new type of anti-rotation structure for vehicle body suspension assembly bolts includes a vehicle frame 1 and a vehicle body support plate 3. Figure 6As shown, the frame 1 includes a frame support block 101, and a flap 102 is fixedly connected to the side wall of the frame support block 101. By providing the flap 102, the frame support block 101 and the side wall of the frame 1 can be welded more firmly, the contact area between the two is increased, and the connection strength between the two is improved; an opening 103 is fixedly opened on the top of the frame support block 101, and a buffer body 2 is fixedly connected to the top of the frame support block 101. The vehicle body and the frame 1 are connected through the buffer body 2, which not only supports the vehicle body, but also reduces the vibration transmitted upward from the frame 1, thereby increasing the riding comfort of the passengers inside the vehicle body; as shown Figure 4 As shown, the buffer body 2 includes a rubber pad 201, and a sleeve 202 is provided inside the rubber pad 201. The setting of the sleeve 202 can prevent the rubber pad 201 from deforming after being compressed, causing the rubber pad 201 to contact and rub against the butterfly bolt 601, causing damage to the rubber pad 201 and reducing the service life of the rubber pad 201;

[0027] The bottom of the rubber pad 201 is fixedly connected to a stabilizing seat 203, and a fixing bolt 204 is provided on the stabilizing seat 203. The fixing bolt 204 cooperates with the opening 103, and the stabilizing seat 203 is fixed together with the frame support block 101 through the fixing bolt 204, providing an upward support force for the rubber pad 201. A fastening component 6 is provided inside the buffer body 2. By setting the fastening component 6, the vehicle body anti-rotation plate 5, the reinforcing support plate 4, the vehicle body support plate 3, the bonding plate 7 and the buffer body 2 are connected together, so that the downward pressure of the vehicle body can be smoothly transmitted to the buffer body 2; a positioning hole is fixedly provided on the inner side of the vehicle body support plate 3 301, the outer side of the body support plate 3 is fixedly provided with a first mounting hole 302 and a second positioning hole 303. The body support plate 3 is fixedly connected with a reinforcing support plate 4 and a bonding plate 7. By providing the reinforcing support plate 4 and the bonding plate 7, the structural strength of the body support plate 3 can be strengthened, and the stability of the connection between the body support plate 3 and the buffer body 2 can be improved. Since the connection between the body and the frame 1 needs to frequently withstand the stress concentration at this location due to the shaking of the vehicle body, the reinforcing support plate 4 and the bonding plate 7 can effectively transfer the stress concentration at this location to other locations of the body support plate 3, thereby dissipating the stress and extending the service life of the body support plate 3;

[0028] like Figure 7 As shown, the reinforcing support plate 4 is fixedly connected to a vehicle body anti-rotation plate 5, which cooperates with a fastening assembly 6. By providing the vehicle body anti-rotation plate 5, the butterfly bolt 601 can be directly locked by it, limiting its circumferential rotation and axial movement, making it easier for workers to complete assembly directly using nuts, without the need for additional workers to perform locking operations.

[0029] like Figure 5As shown, the fastening assembly 6 includes a butterfly bolt 601, and the top of the butterfly bolt 601 is fixedly connected to a limiting protrusion 601A. During assembly, the limiting protrusion 601A will be stuck in the anti-rotation plate 5 of the vehicle body. After being stuck, the butterfly bolt 601 cannot rotate or move axially, and the position of the butterfly bolt 601 is limited; a limiting snap ring 603 is provided at the bottom of the butterfly bolt 601, and the limiting snap ring 603 cooperates with the bottom of the rubber pad 201. The setting of the limiting snap ring 603 can connect the rubber pad 201 with the vehicle body support plate 3 to prevent the rubber pad 201 from accidentally detaching from the vehicle body; a nut 602 is provided at the bottom of the limiting snap ring 603, and the nut 602 is threadedly connected to the butterfly bolt 601, and the lower part of the butterfly bolt 601 cooperates with the sleeve 202.

[0030] like Figure 3 As shown, a folded edge 402 is fixedly provided on the side wall of the reinforcing support plate 4, and the folded edge 402 is fixedly connected to the upper part of the vehicle body support plate 3. By providing the folded edge 402, the contact area between the reinforcing support plate 4 and the vehicle body support plate 3 can be further increased, so that the two can fit together more closely, and the connection strength of the welding between the two is improved; a positioning hole 3 401 is fixedly provided in the middle of the reinforcing support plate 4, and the positioning hole 3 401 cooperates with the positioning hole 1 301. By providing the positioning hole 301, the reinforcing support plate 4 can be quickly and accurately placed on the vehicle body support plate 3 and welded and fixed; a mounting hole 2 403 is fixedly provided on the outer side of the reinforcing support plate 4, and the mounting hole 2 403 cooperates with the mounting hole 1 302.

[0031] A second folding edge 701 is fixedly provided on the side wall of the bonding plate 7, and the second folding edge 701 is fixedly connected to the lower part of the vehicle body support plate 3. By setting the second folding edge 701, the connection strength of the bonding plate 7 and the vehicle body support plate 3 can be improved; a fourth mounting hole 702 is fixedly provided in the middle part of the bonding plate 7, and the fourth mounting hole 702 cooperates with the first mounting hole 302; a fourth positioning hole 703 is fixedly provided at the rear part of the bonding plate 7, and the fourth positioning hole 703 cooperates with the second positioning hole 303. By setting the fourth positioning hole 703, the bonding plate 7 can be quickly and accurately placed on the vehicle body support plate 3 and welded and fixed.

[0032] like Figure 8 As shown, a welding plate 501 is fixedly connected to the vehicle body anti-rotation plate 5. The welding plate 501 has a large area, which is convenient for fixing the vehicle body anti-rotation plate 5 to the reinforcing support plate 4 and providing connection strength between the vehicle body anti-rotation plate 5 and the reinforcing support plate 4. A mounting hole 3 503 is fixedly opened in the middle of the vehicle body anti-rotation plate 5. A flip-up foot 502 is fixedly connected to the side wall of the vehicle body anti-rotation plate 5. The flip-up foot 502 cooperates with the limiting convex plate 601A, and an anti-rocking plate 502A is fixedly connected to the top of the flip-up foot 502. The flip-up foot 502 is positioned at the upper left corner and the lower right corner of the vehicle body anti-rotation plate 5. Compared with the flip-up foot 502 being placed in the middle of the vehicle body anti-rotation plate 5, the flip-up foot 502 is arranged as follows. Figure 8 The position in the middle allows the side of the limiting protrusion 601A to contact the side of the flip-up foot 502 in a surface contact form, which can bear greater force and is less likely to cause damage to the structures of the two. The setting of the anti-rocker plate 502A can axially limit the butterfly bolt 601.

[0033] like Figure 2 As shown, a support tube 8 is fixedly connected between the reinforcing support plate 4 and the bonding plate 7, and the support tube 8 cooperates with the upper part of the butterfly bolt 601. By providing the support tube 8, the direct connection strength between the reinforcing support plate 4 and the bonding plate 7 is further increased, making the structural strength of the vehicle body support plate 3 higher.

[0034] The present invention can strengthen the structural strength of the vehicle body support plate 3 and improve the stability of the connection between the vehicle body support plate 3 and the buffer body 2 by providing the reinforcing support plate 4 and the bonding plate 7. Since the connection between the vehicle body and the frame 1 needs to often withstand the stress concentration at this location due to the shaking of the vehicle body, the reinforcing support plate 4 and the bonding plate 7 can effectively transfer the stress concentration thereto to other locations of the vehicle body support plate 3, diverge the stress, and extend the service life of the vehicle body support plate 3; by providing the vehicle body anti-rotation plate 5, the butterfly bolt 601 can be directly locked by it, limiting its circumferential rotation and axial movement, making it convenient for workers to directly use nuts to complete the assembly without adding additional workers to perform locking operations.
