It is located at the rear of the vehicle and connected to the left and right rear longitudinal beams. Its main functions are as follows: Strengthening the rigidity and stability of the vehicle body: The front connecting plate of the rear longitudinal beam strengthens the overall structural strength of the vehicle body by connecting the two rear longitudinal beams, and improves the stability and safety of the vehicle. Undertaking and dispersing collision force: When the rear collision of the car occurs, the front connecting plate of the rear longitudinal beam can bear the force generated by the collision and disperse these forces to different parts of the vehicle body, reducing the direct impact on the vehicle body, thereby protecting the safety of the vehicle and passengers. Improving the accuracy and stability of the suspension system: The front connecting plate of the rear longitudinal beam can also improve the accuracy and stability of the suspension system of the car, which helps to improve the driving stability and comfort of the vehicle. Due to the lack of protective structure, the front connecting plate of the traditional rear longitudinal beam is easily directly hit by foreign objects, and then the front connecting plate of the rear longitudinal beam is easily deformed or even broken by collision. Therefore, a front connecting plate of the rear longitudinal beam is needed to solve the above problems. Utility Model Content

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a front connecting plate of a rear longitudinal beam includes a connecting plate body 1, a plurality of rubber pad installation grooves 5 are opened on the outer wall of the connecting plate body 1, a plurality of protective rubber pads 2 are fixedly installed in the connecting plate body 1, and the plurality of protective rubber pads 2 are respectively fixedly installed in the plurality of rubber pad installation grooves 5 opened on the outer wall of the connecting plate body 1. By arranging the protective rubber pads 2 on the connecting plate body 1, the protective rubber pads 2 can avoid direct contact between the buffer protection structure 4 and the connecting plate body 1, thereby protecting the connecting plate body 1 and reducing the probability of damage to the connecting plate body 1.

[0021] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a mounting fixture 3 is fixedly installed on the outer wall of the connecting plate body 1. The mounting fixture 3 is composed of a U-shaped clamp 6 and an L-shaped connecting plate 7. There are two L-shaped connecting plates 7 and both are fixedly installed on one end of the U-shaped clamp 6. A mounting hole 8 is opened on the L-shaped connecting plate 7 on the mounting fixture 3. The L-shaped connecting plate 7 can be fixedly installed on the outer wall of the connecting plate body 1 by bolts. A plurality of buffer protection structures 4 are fixedly installed on the inner wall of the U-shaped clamp 6. The buffer protection structure 4 is also located at the outer end of the protective rubber pad 2. The buffer protection structure 4 is composed of an outer substrate 9, an inner substrate 11 and an S-shaped energy absorbing plate 10. The S-shaped energy absorbing plate 10 is fixedly installed between the outer substrate 9 and the inner substrate 11. The outer substrate 9 on the buffer protection structure 4 is located on the outside of the inner substrate 11. The outer substrate 9 on the buffer protection structure 4 is fixedly connected to the inner wall of the U-shaped clamp 6. The layer substrate 11 is in contact with the outer end of the protective rubber pad 2. When in use, the L-shaped connecting plate 7 on the mounting fixture 3 can be fixed to the outer wall of the connecting plate body 1 by bolts and other fixings.
