The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0025] In the description of the present invention, it should be noted that the orientation or position relationship indicated in the description is based on the orientation or position relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the referred parts or elements must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] See also Figure 1 and Figure 2 The utility model provides a reinforcing support structure of a support rod, which is used to install a support rod 10 supporting a back door, and specifically includes a support member 20, a water trough 30, a C-pillar reinforcement plate 40, a mounting member 50, and a reinforcement member 60. The water trough 30 is installed on the C-pillar reinforcement plate 40 and extends downward and backward. The mounting member 50 is installed on the inner wall of the water trough 30. The mounting member 50 is specifically a plate-shaped structure, which is arranged parallel to the length direction of the water trough 30. The support rod 10 is connected to the mounting member 50 and extends along the water trough 30. The reinforcement member 60 is installed on the outer wall of the water trough 30. One end of the support member 20 is connected to the reinforcement member 60, and the other end is connected to the side of the C-pillar reinforcement plate 40. The reinforced support structure provided by the utility model can improve the installation strength of the installation point of the support rod 10 by setting the reinforcement member 60, and avoid the water flow channel 30 from being deformed by force. By setting the support member 20 and connecting the two ends of the support member 20 with the reinforcement member 60 and the C-pillar reinforcement plate 40 respectively, a stronger support structure and force transmission path are formed, which can disperse the force from the support rod 10 on the water flow channel 30, avoid deformation of the water flow channel 30 and both sides of the rear part of the vehicle body, reduce the displacement, and improve the NTF level of the rear part of the vehicle body.

[0027] Furthermore, if Figure 3 and Figure 4 As shown, a projection welding nut 70 is provided at one end of the support member 20, and a mounting hole 80 corresponding to the projection welding nut 70 is provided on the mounting member 50, the reinforcement member 60, and the water trough 30, and the positions of the mounting holes 80 on the mounting member 50, the reinforcement member 60, and the water trough 30 correspond to each other. The screw 90 passes through the mounting member 50, the reinforcement member 60, and the mounting holes 80 on the water trough 30 in sequence, and is screwed with the projection welding nut 70 at one end of the support member 20, so as to fix the mounting member 50, the reinforcement member 60, and one end of the support member 20 to the water trough 30. Since the reinforcement member 60 increases the thickness of the water trough 30, the installation strength of the mounting point of the support rod 10 can be improved to prevent the water trough 30 from being deformed by force.

[0028] Please continue reading Figure 3 and Figure 4The reinforcement 60 includes a first reinforcement portion 61 and a second reinforcement portion 62. The second reinforcement portion 62 is connected to the bottom of the first reinforcement portion 61 and extends from the bottom of the first reinforcement portion 61 in a direction away from the support member 20. The first reinforcement portion 61 is installed on the outer wall of the water trough 30, and the second reinforcement portion 62 is installed between the bottom of the water trough 30 and the C-pillar reinforcement plate 40. Specifically, the first reinforcement portion 61 is welded to the outer wall of the water trough 30, and the second reinforcement portion 62 is welded to the bottom of the water trough 30. The settings of the first reinforcement portion 61 and the second reinforcement portion 62 respectively increase the thickness of the side wall and the bottom of the water trough 30, thereby improving the installation strength of the mounting point of the support rod 10 and preventing the water trough 30 from being deformed by force.

[0029] See also Figure 5 The support member 20 includes a first support portion 21 and a second support portion 22. The first support portion 21 extends along the width direction of the automobile, and the second support portion 22 extends forward and outward from the first support portion 21. One end of the first support portion 21 is provided with a mounting ear 211 extending outward from both sides of the end, and the projection welding nut 70 is arranged on the mounting ear 211. The first support portion 21 is connected to the reinforcement member 60 through the mounting ear 211, and the other end of the first support portion 21 is connected to one end of the second support portion 22, and the other end of the second support portion 22 is connected to the C-pillar reinforcement plate 40. The first support portion 21 and the second support portion 22 can be welded together. The force received by the support rod 10 will be transmitted to the first support portion 21 and the second support portion 22 through the water flow groove 30 and the reinforcement member 60, and finally transmitted to the C-pillar reinforcement plate 40. Since the C-pillar reinforcement plate 40 has a large mass and can generate a large inertia, it can restrain the vibration of the back door, avoid deformation of the water flow groove 30 and the positions on both sides of the rear of the entire vehicle body, and reduce the displacement.

[0030] See also Figure 6The first support portion 21 includes a first top plate 212 and two first side plates 213. The first top plate 212 is tilted downward from top to bottom. The top ends of the two first side plates 213 are connected to the two sides of the first top plate 212 and extend vertically downward from the two sides of the first top plate 212. The bottom ends of the two first side plates 213 are connected to the top of the C-pillar reinforcement plate 40. Specifically, the bottom of the first side plate 213 can be welded to the top of the C-pillar reinforcement plate 40 by welding. The mounting ears 211 are respectively arranged at one end of the two first side plates 213. The mounting ears 211 extend vertically outward from one end of the two first side plates 213, so that the first support portion 21 forms a "T"-shaped structure as a whole, thereby improving the support strength of the first support portion 21. In addition, the cross section of the first support portion 21 is generally U-shaped, and its open end is connected to the C-pillar reinforcement plate 40, so that a closed structure can be formed, further improving the support strength of the first support portion 21. In addition, the inclined setting of the first top plate 212 can facilitate the transmission of force, transferring the force from the top of the C-pillar reinforcement plate 40 to the side end with a larger area, and effectively dispersing the force from the support rod 10 on the water channel 30.

[0031] See also Figure 7 The structure of the second support portion 22 is designed according to the structure of the C-pillar reinforcement plate 40. Specifically, the second support portion 22 includes a connecting portion 221 and a fitting portion 222. One end of the connecting portion 221 is connected to the inner wall of the first support portion 21, and the bottom end is connected to the top of the C-pillar reinforcement plate 40. The bottom end of the connecting portion 221 can be welded to the top of the C-pillar reinforcement plate 40 by welding. The other end of the connecting portion 221 is connected to one end of the fitting portion 222, and the fitting portion 222 is connected to the C-pillar reinforcement plate 40. The connection part 221 is configured to transmit the force from the first support part 21 and to disperse the force from the top of the C-pillar reinforcement plate 40 to the side of the C-pillar reinforcement plate 40. Therefore, the structure of the connection part 221 is similar to that of the first support part 21, specifically including a second top plate 221a and two second side plates 221b. The second top plate 221a is tilted from top to bottom, and the tilt degree is basically the same as that of the first top plate 212. The top ends of the two second side plates 221b are connected to the two sides of the second top plate 221a and extend vertically downward from the two sides of the second top 221a. The bottom ends of the two second side plates 221b are connected to the top of the C-pillar reinforcement plate 40, and the two can be welded into one. The fitting part 222 is welded to the side of the C-pillar reinforcement plate 40, and the force is dispersed to the entire side wall of the C-pillar reinforcement plate 40 through the fitting part 222. In order to ensure the firmness of the connection between the fitting portion 222 and the side wall of the C-pillar reinforcement plate 40 , a structural adhesive 222 b is further provided on the fitting portion 222 , and the structural adhesive 222 b can be used to reinforce the places where welding cannot reach.

[0032] Furthermore, since the first support portion 21 has a certain thickness, and the connecting portion 221 is connected to the inner wall of the other end of the first support portion 21, in order to ensure that the force can be smoothly transmitted after the connection, a bending portion 221c is provided on the connecting portion 221, so that the end of the connecting portion 221 close to the first support portion 21 and the end away from the first support portion 21 form a step, so that after the second support portion 22 is connected to the first support portion 21, the other end of the first support portion 21 just contacts or abuts against the step, and the upper surface of the end of the connecting portion 221 away from the first support portion 21 can be flush with the upper surface of the first support portion 21, so that the force can be smoothly transmitted between the first top plate 212 and the second top plate 221a. The other end of the fitting portion 222 is provided with an opening facing the triangular window 41 (see Figure 1 ) has a U-shaped opening 222a, and both ends of the opening 222a are connected to the two sides of a corner of the triangular window 41, further improving the connection strength between the fitting portion 222 and the side of the C-pillar reinforcement plate 40.
