And it is only for the convenience of describing the present invention and simplifying the description, and it does not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, so it cannot be understood as limiting the specific protection scope of the present invention.

[0029] Please also read Figure 1 and Figure 2 The vehicle body side rear force transmission reinforcement structure provided by the utility model is now described. The vehicle body side rear force transmission reinforcement structure comprises a C-pillar assembly 1, a D-pillar assembly 5 and a rear wheel cover assembly 2. The C-pillar assembly 1 is connected to the D-pillar assembly 5 through a CD-pillar connecting plate 8. The D-pillar assembly 5 is connected to the rear wheel cover assembly 2 through a rear wheel cover and side panel connecting plate 3. The rear wheel cover assembly 2 is connected to the C-pillar assembly 1 to form a closed-loop force transmission channel 9.

[0030] The force transmission reinforcement structure at the rear of the vehicle body side also includes an audio amplifier mounting bracket 4 and a back door controller mounting bracket 6 arranged in a closed-loop force transmission channel 9; the front and rear ends of the audio amplifier mounting bracket 4 are respectively connected to the rear wheel cover assembly 2 and the D-pillar assembly 5 to form a first force transmission channel 10; the upper and lower ends of the back door controller mounting bracket 6 are respectively connected to the CD-pillar connecting plate 8 and the audio amplifier mounting bracket 4 to form a second force transmission channel 11.

[0031] Compared with the prior art, the force transmission reinforcement structure of the rear part of the vehicle side provided by the utility model has the following beneficial effects: (1) the C-pillar assembly 1, the CD-pillar connecting plate 8, the D-pillar assembly 5, the rear wheel cover and the side panel connecting plate 3, and the rear wheel cover assembly 2 are connected in sequence, and the rear wheel cover assembly 2 is connected to the C-pillar assembly 1 to form a closed-loop force transmission channel 9, which can improve the force transmission effect of the rear area of ​​the vehicle side panel, avoid the side impact force of the rear part of the vehicle side panel and the exciting force of the rear wheel cover area from being transmitted to the rear seats, and improve the comfort and safety of the rear passengers; due to the connection of the force transmission channel (2) The audio amplifier mounting bracket 4 is connected between the rear wheel cover assembly 2 and the D-pillar assembly 5 to form a first force transmission channel 10. The first force transmission channel 10 is connected to the closed-loop force transmission channel 9, which not only provides more force transmission channels for collision force or road excitation force, but also the collision force or excitation force transmitted from different directions can be offset backwards, thereby avoiding the transmission of the excitation force or collision force to the rear seats, thereby improving the safety of the rear passengers. The comfort and safety of the passengers in the vehicle are improved; (3) the back door controller mounting bracket 6 connected between the CD column connecting plate 8 and the audio amplifier mounting bracket 4 forms a second force transmission channel 11, which decomposes the excitation force of the first force transmission channel 10 and forms a connection with the closed-loop force transmission channel 9. Through the force decomposition and the interconnection between the force transmission channels, the excitation force is transmitted along each force transmission channel, thereby avoiding or alleviating the energy transmitted by the excitation force to the rear seats, thereby improving the comfort and safety of the rear passengers in the vehicle; (4) using the back door controller The mounting bracket 6 and the audio amplifier mounting bracket 4 are installed as electrical components and integrated into a force transmission channel through a rational design, which not only realizes the reliable installation of the electrical components, but also reduces the transmission of the vibration energy of the rear wheel, thus having a dual effect; (5) the exciting force is decomposed, attenuated, and offset gradually during the force transmission process on the closed-loop force transmission channel 9 and the decomposed force transmission channel, and a part of it is transmitted to the vehicle body frame through the C-pillar assembly 1 and the D-pillar assembly 5, thereby reducing the risk of vibration noise of the rear seats and improving the experience of the rear passengers and the durability of the entire vehicle.

[0032] The tailgate controller mounting bracket 6 of the present application not only provides an installation position for the controller, but also forms an H-shaped structure with the CD column connecting plate 8 and the audio amplifier mounting bracket 4, thereby increasing the force transmission channel at the rear of the vehicle side panel, strengthening the overall structure of the rear of the side panel, reducing the energy transmission of the rear wheel vibration, and helping to improve the rear seat riding experience and the durability of the vehicle.

[0033] The present application directly utilizes the back door controller mounting bracket 6 and the audio amplifier mounting bracket 4 to construct a force transmission channel, which not only facilitates the installation of the back door controller and the audio amplifier, but also improves the strength of the installation area and the deformation resistance of the area, thereby ensuring the reliability of each component after installation.

[0034] In some embodiments, Figure 2 and Figure 5 As shown, the back door controller mounting bracket 6 has a first connection portion 61, a controller mounting section 62, and a second connection portion 63 from top to bottom, and the width of the controller mounting section 62 along the front-to-back direction is greater than the width of the second connection portion 63. The ground excitation force received by the rear wheel cover assembly 2 is transmitted to the audio amplifier mounting bracket 4, and then transmitted to the CD column connecting plate 8 through the back door controller mounting bracket 6, and then transmitted to the C column assembly 1 and the D column assembly 5 through the CD column connecting plate 8, and then directly transmitted to the D column assembly 5. The energy value of the excitation force on one channel is dispersed by force decomposition, thereby reducing the vibration energy of the excitation force.

[0035] The width of the controller mounting section 62 is greater than the width of the second connecting portion 63. When the exciting force is transmitted to the controller mounting section 62, the vibration energy of the controller mounted thereon can be reduced, thereby reducing the impact of the vibration excitation on the back door controller.

[0036] A card interface for installing a back door controller is provided on the controller installation section 62 to facilitate the installation of the back door controller.

[0037] Here, in order to facilitate the later installation and removal and replacement of the back door controller, the angle c formed by the installation surface of the controller installation section 62 and the vertical plane in the front-to-back direction is designed to be between 10° and 20° (see Figure 4 ), preferably 15°.

[0038] In some embodiments, see Figure 3 , the lower end of the second connection part 63 is tilted backward and connected to the audio amplifier mounting bracket 4, and the angle a formed by the second connection part 63 is an obtuse angle. The second connection part 63 is connected to the audio amplifier mounting bracket 4, and the exciting force is transmitted to the controller mounting section 62 through the second connection part 63. The second connection part 63 is tilted to form a bend, which can increase the transmission path and transmission time of the exciting force in this section, thereby improving the effect of exciting force attenuation and reducing the excitation effect of the exciting force on the controller mounting section 62. The obtuse angle formed can ensure the smooth transmission of the exciting force and avoid the poor transmission of the exciting force in the dead corner, which leads to stress concentration damage.

[0039] Specifically, the angle a is 130° to 140°, for example, 135°, 137°, etc. Of course, the second connecting portion 63 is tilted backwards so as to avoid the second protruding portion 44 on the audio amplifier mounting bracket 4 .

[0040] In some embodiments, Figure 3As shown, a first reinforcing rib is provided on the controller mounting section 62, and a second reinforcing rib is provided on the second connecting portion 63. The design of the reinforcing rib can improve the structural rigidity of the component itself, thereby improving the force transmission reliability and anti-deformation ability of the component; a reinforcing rib structure is also provided on the audio amplifier mounting bracket 4, which will not be explained later.

[0041] In some embodiments, Figure 1 As shown, the first connection part 61 and the second connection part 63 are respectively detachably connected to the CD column connection plate 8 and the audio amplifier mounting bracket 4 by fasteners. Bolts are used as fasteners at both ends of the back door controller mounting bracket 6 for detachable connection, without welding process, which provides convenience for later product replacement.

[0042] In some embodiments, Figure 3 As shown, the audio amplifier mounting bracket 4 has a third connection portion 43, an audio amplifier mounting section 42 and a fourth connection portion 41 from front to back, the third connection portion 43 is tilted downward, and the angle b formed between the third connection portion 43 and the audio amplifier mounting section 42 is an obtuse angle. The audio amplifier mounting bracket 4 not only serves as a mounting structure for the audio amplifier, but also increases a force transmission channel between the rear wheel housing assembly 2 and the D-pillar assembly 5, thereby improving the effect of vibration reduction and noise reduction.

[0043] The third connection portion 43 connected to the rear wheel cover assembly 2 is tilted, which also increases the length of the force transmission path and is beneficial to the attenuation of the exciting force.

[0044] Furthermore, if Figure 3 As shown, the angle b ranges from 140° to 160°, ensuring smooth transmission of the exciting force.

[0045] In some embodiments, Figure 3 As shown, the upper edge of the audio amplifier mounting section 42 has a first protruding portion 45 protruding upward, and the lower edge thereof has a second protruding portion 44 protruding downward, and the connection point of the back door controller mounting bracket 6 avoids the second protruding portion 44. By configuring the two protruding portions extending in different directions on the audio amplifier mounting section 42, the structural rigidity of the audio amplifier mounting bracket 4 can be improved, thereby reducing the influence of the exciting force on the audio amplifier after installation, and avoiding the problem of failure of the installation fixing point.

[0046] In some embodiments, see Figure 3 As shown, the first protruding portion 45 and the second protruding portion 44 are staggered in the front-to-back direction. In this way, when other peripheral related components are connected, the exciting force can be transmitted from different positions to different directions, thereby improving the effect of force transmission.

[0047] Since the audio amplifier mounting bracket 4 serves as a mounting structure for the audio amplifier, wiring harness mounting points are also provided on the two protruding portions to fix the wiring harness of the audio amplifier.

[0048] In some embodiments, see Figure 1 and Figure 2 The rear wheel cover assembly 2 also has a rear wheel cover reinforcement part 21 connected to the CD column connecting plate 8. The rear wheel cover reinforcement part 21 is connected to the D column assembly 5 through the rear wheel cover connecting plate 7 to form a third force transmission channel 12; wherein, there is a gap between the rear wheel cover connecting plate 7 and the back door controller mounting bracket 6. It can be seen that the exciting force of the rear wheel cover assembly 2 can also be transmitted to the CD column connecting plate 8 through the rear wheel cover reinforcement part 21, and can also be transmitted to the D column assembly 5 through the rear wheel cover reinforcement part 21 and the rear wheel cover connecting plate 7, thereby increasing the transmission path of the ground exciting force, making the exciting force dispersed and transmitted, reducing the energy value of the exciting force on the same path, and avoiding the risk of the exciting force being transmitted to the rear seats.

[0049] In the above embodiments, the description of each embodiment has its own emphasis. For parts that are not described or recorded in detail in a certain embodiment, reference can be made to the relevant descriptions of other embodiments.

[0050] Based on the same inventive concept, an embodiment of the present application also provides a vehicle, including the aforementioned vehicle body side rear force transmission reinforcement structure.

[0051] In the vehicle provided by the embodiment of the utility model, the exciting force is decomposed, attenuated, and offset gradually during the force transmission process in the closed-loop force transmission channel 9 and the decomposed force transmission channel, and is partially transmitted to the vehicle body frame through the C-pillar assembly 1 and the D-pillar assembly 5, thereby reducing the risk of vibration and noise of the rear seats, and improving the experience of the rear passengers and the durability of the entire vehicle.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
