[0029] Combined with Figures 1 to 6 As shown, in the figure, the Z-axis represents the vehicle height direction, the positive Z-axis represents upward, the negative Z-axis represents downward, the X-axis represents the vehicle length direction, the positive X-axis represents forward, the negative X-axis represents backward, the Y-axis represents the vehicle width direction, the positive Y-axis represents left, and the negative Y-axis represents right.

[0030] The present utility model provides a sidewall connection assembly 200 for an instrument panel reinforcement beam 100. The instrument panel reinforcement beam 100 has a first end 11 close to the driver's seat and a second end 12 close to the passenger's seat. The sidewall connection assembly 200 includes a first bracket 21 and a second bracket 22, wherein: the first bracket 21 is connected to the first end 11, and the first bracket 21 is provided with a first mounting hole 211, a second mounting hole 212, and a third mounting hole 213 along the vehicle width direction to enclose a triangle, and the center point of the first end 11 is located within the triangle. The first bracket 21 is connected to the driver's sidewall structure through the first mounting hole 211, the second mounting hole 212, and the third mounting hole 213; the second bracket 22 is connected to the second end 12, and the second bracket 22 is provided with a fourth mounting hole 221 and a fifth mounting hole 222 along the vehicle width direction. The fourth mounting hole 221 and the fifth mounting hole 222 are respectively located on the upper side and the lower side of the second end 12. The second bracket 22 is connected to the passenger's sidewall structure through the fourth mounting hole 221 and the fifth mounting hole 222.

[0031] Combined with Figures 1 to 3 、 Figure 5 As shown, the instrument panel reinforcement beam 100 is usually a tubular beam in the shape of a round tube. The instrument panel reinforcement beam 100 is parallel to the Y-axis direction in the figure. Taking a vehicle model with the driver's seat on the left as an example, the first end 11 of the instrument panel reinforcement beam 100 close to the positive Y-axis direction, and the first end 11 and the first bracket 21 are fixedly connected by means such as welding and screwing.

[0032] Combined with Figure 3 As shown in this embodiment, the first bracket 21 is provided with a first mounting hole 211, a second mounting hole 212, and a third mounting hole 213 (the central axes of the three through-hole structures are all parallel to the Y-axis direction in the figure, that is, the vehicle width direction). The first mounting hole 211 and the second mounting hole 212 are both located on the upper side of the first end 11 (that is, on the positive Z-axis side), and the third mounting hole 213 is located on the lower side of the first end 11 (that is, on the negative Z-axis side). The first mounting hole 211, the second mounting hole 212, and the third mounting hole 213 form a triangle outlined by the dashed line in Figure 3 . The center of the first end 11 refers to the center of the circular cross-section of the tubular beam, and the center of the first end 11 is located within the triangle (including the case where the center is located on the boundary line of the triangle). Exemplarily, three bolts or three pins pass through the above through-hole structures and are then connected to the driver's sidewall structure.

[0033] Combined with Figure 5As shown, in this embodiment, the second bracket 22 is provided with a fourth mounting hole 221 and a fifth mounting hole 222 (the central axes of the two through-hole structures are both parallel to the Y-axis direction in the figure, that is, the vehicle width direction). The fourth mounting hole 221 is located on the upper side of the second end 12 (i.e., on the positive side along the Z-axis), and the fifth mounting hole 222 is located on the lower side of the second end 12 (i.e., on the negative side along the Z-axis). Exemplarily, two bolts or two pin shafts pass through the above through-hole structures and are then connected to the co-pilot side wall structure.

[0034] The side wall connection assembly 200 in the present utility model is used to connect the instrument panel reinforcement beam 100 and the vehicle body side wall structure (including the driver's side wall structure and the co-pilot side wall structure). The first bracket 21 among them is connected to the driver's side wall structure through the first mounting hole 211, the second mounting hole 212, and the third mounting hole 213. The center point of the first end 11 of the instrument panel reinforcement beam 100 is located within the triangle formed by the first mounting hole 211, the second mounting hole 212, and the third mounting hole 213, so that the position where the first end 11 is located is strengthened and reinforced, improving the connection stability between the first bracket 21 and the driver's side wall structure; the second bracket 22 among them strengthens and reinforces the upper and lower sides of the second end 12 respectively through the fourth mounting hole 221 and the fifth mounting hole 222, improving the connection stability between the second bracket 22 and the co-pilot side wall structure; compared with the scheme of the side wall connection bracket of traditional vehicles that is provided with both X-direction and Y-direction connection structures at the same time, the first mounting hole 211, the second mounting hole 212, the third mounting hole 213, the fourth mounting hole 221, and the fifth mounting hole 222 in the present utility model are all Y-direction connection structures, canceling the X-direction connection structure, thereby reducing the overall weight while ensuring that the overall strength and stiffness meet the design requirements.

[0035] Further, a first sliding groove 214 extending backward is provided at the front side edge of the first bracket 21, and a first connection column 01 is provided on the driver's side wall structure to slide to the rear end of the first sliding groove 214.

[0036] Combined Figure 1 and Figure 3As shown, a first sliding groove 214 extending rearward (i.e., toward the negative X-axis direction) is provided on the front edge of the first bracket 21 (i.e., the edge closer to the positive X-axis direction). A first connecting post 01 is provided on the driver's side surround structure (the driver's side surround structure is not shown in the figure). During the assembly process, first, the first connecting post 01 is placed into the first sliding groove 214 from the front edge of the first bracket 21. The first connecting post 01 supports the first bracket 21 through the first sliding groove 214. By moving the first bracket 21, the first connecting post 01 finally slides to the rear end of the first sliding groove 214 (i.e., the end closer to the negative X-axis direction). At this time, the first mounting hole 211, the second mounting hole 212, and the third mounting hole 213 on the first bracket 21 are in corresponding positions with the corresponding holes on the driver's side surround structure.

[0037] In this way, through the cooperation of the first sliding groove 214 and the first connecting post 01, when assembling the first bracket 21, the first connecting post 01 can be first placed into the first sliding groove 214. By relatively sliding the first connecting post 01 to the rear end of the first sliding groove 214, it is assisted to align the first mounting hole 211, the second mounting hole 212, and the third mounting hole 213 with the holes on the driver's side surround structure, improving the assembly convenience of the first bracket 21.

[0038] Further, a first limiting groove 215 extending upward is provided at the rear end of the first sliding groove 214 for limiting cooperation with the first connecting post 01.

[0039] Combined Figure 1 and Figure 3 As shown, a first limiting groove 215 extending upward (i.e., toward the positive Z-axis direction) is provided at the rear end of the first sliding groove 214 (i.e., the end along the negative X-axis direction). When the first connecting post 01 slides to the rear end of the first sliding groove 214, it continues to move upward to slide into the first limiting groove 215 (i.e., the first bracket 21 moves downward to make the first connecting post 01 cooperate with the first limiting groove 215). The first limiting groove 215 matches the outer shape of the first connecting post 01, thus realizing the limiting cooperation.

[0040] In this way, through the limiting cooperation between the first limiting groove 215 and the first connecting post 01, the assembly convenience of the first bracket 21 is further improved.

[0041] Further, a second connecting post 02 is provided on the driver's side surround structure, and a second limiting groove 216 extending upward is provided on the lower edge of the first bracket 21 for limiting cooperation with the second connecting post 02.

[0042] Combined Figure 1 and Figure 3As shown, a second connecting column 02 is also provided on the main driver side structure, and a second limiting groove 216 extending upward (i.e. extending toward the positive direction of the Z axis) is provided on the lower edge of the first bracket 21 (i.e. the edge along the opposite side of the Z axis), and the second connecting column 02 matches the shape of the second limiting groove 216 to achieve limiting cooperation.

[0043] In this way, when the first connecting column 01 slides to the rear end of the first sliding groove 214, the first connecting column 01 corresponds to the first limiting groove 215, and the second connecting column 02 also corresponds to the second limiting groove 216. Then the first connecting column 01 and the second connecting column 02 are moved upward, so that the first connecting column 01 is limited and matched with the first limiting groove 215, and the second connecting column 02 is limited and matched with the second limiting groove 216, so that the first bracket 21 is positioned between the main driver's side panel structure, which further improves the assembly convenience of the first bracket 21.

[0044] Furthermore, a first clamping hole 217 and a second clamping hole 225 are respectively provided on the first bracket 21 and the second bracket 22 .

[0045] Combination Figure 1 , Figure 3 and Figure 4 As shown, the first bracket 21 is provided with a first clamping hole 217 for the robot arm to clamp and fix. Figure 2 , Figure 5 and Figure 6 As shown, the second bracket 22 is provided with a second clamping hole 225 for clamping and fixing by the robot arm, and its specific structure can be designed according to the clamping device of the robot arm.

[0046] In this way, the first clamping hole 217 and the second clamping hole 225 provide convenience for the clamping of the robot arm. Compared with the solution of adding an additional clamping bracket on traditional models, the utility model integrates the clamping bracket with the side panel connection assembly 200, which also reduces the overall weight to a certain extent.

[0047] Furthermore, the edge of the first clamping hole 217 is provided with a first flange portion 2171 extending toward the co-pilot side, and the edge of the second clamping hole 225 is provided with a second flange portion 2251 extending toward the driver side.

[0048] Combination Figure 4 As shown, the edge of the first clamping hole 217 is provided with a first flange portion 2171 extending toward the co-pilot side (ie, toward the side opposite to the Y axis), Figure 6 As shown, the edge of the second clamping hole 225 is provided with a second flange portion 2251 extending toward the main driving side (ie, toward the positive side of the Y axis).

[0049] In this way, the first flanging portion 2171 and the second flanging portion 2251 respectively strengthen and reinforce the periphery of the first clamping hole 217 and the periphery of the second clamping hole 225.

[0050] Further, a second sliding groove 223 extending rearward is provided at the front edge of the second bracket 22, and a third connecting post 03 is provided on the co-pilot side surround structure to slide to the rear end of the second sliding groove 223.

[0051] Combined Figure 2 and Figure 5 As shown, a second sliding groove 223 extending rearward (i.e., extending in the reverse direction of the X axis) is provided at the front edge of the second bracket 22 (i.e., the edge closer to the positive direction of the X axis), and a third connecting post 03 is provided on the co-pilot side surround structure (the co-pilot side surround structure is not shown in the figure). When assembling the second bracket 22, the third connecting post 03 can be moved into the second sliding groove 223 from the front edge, so that the third connecting post 03 slides along the second sliding groove 223 to the rear end of the second sliding groove 223, and further aligns the fourth mounting hole 221 and the fifth mounting hole 222 with the corresponding hole positions on the co-pilot side surround structure.

[0052] In this way, through the cooperation of the second sliding groove 223 and the third connecting post 03, when assembling the second bracket 22, the third connecting post 03 can be first placed in the second sliding groove 223, and by the relative sliding of the third connecting post 03 to the rear end of the second sliding groove 223, it assists in aligning the fourth mounting hole 221 and the fifth mounting hole 222 with the hole positions on the co-pilot side surround structure, improving the assembly convenience of the second bracket 22.

[0053] Further, a third limiting groove 224 extending upward is provided at the rear end of the second sliding groove 223 to be in limiting cooperation with the third connecting post 03.

[0054] Combined Figure 2 and Figure 5 As shown, the rear end of the second sliding groove 223 (i.e., the end closer to the reverse direction of the X axis) extends upward (i.e., extends in the positive direction of the Z axis). When assembling the second bracket 22, first place the third connecting post 03 into the second sliding groove 223 from the front edge of the second bracket 22, so that the third connecting post 03 slides to the rear end of the second sliding groove 223, and then move the third connecting post 03 upward into the third limiting groove 224 (that is, move the second bracket 22 downward to make the third connecting post 03 cooperate with the third limiting groove 224) to achieve limiting cooperation.

[0055] In this way, through the limiting cooperation between the third limiting groove 224 and the third connecting post 03, the assembly convenience of the second bracket 22 is further improved.

[0056] Further, a first tolerance absorber 2211 is provided on the second bracket 22 corresponding to the fourth mounting hole 221, and a second tolerance absorber 2221 is provided corresponding to the fifth mounting hole 222.

[0057] Combined Figure 2 with Figure 5 As shown, exemplarily, a first tolerance absorber 2211 is provided at the position of the second bracket 22 corresponding to the fourth mounting hole 221. A long bolt passes through the co-driver side panel structure, the first tolerance absorber 2211 and the fourth mounting hole 221 and is installed together with a nut. A second tolerance absorber 2221 is provided at the position of the second bracket 22 corresponding to the fifth mounting hole 222. Another long bolt passes through the co-driver side panel structure, the second tolerance absorber 2221 and the fifth mounting hole 222 and is installed together with a nut, thereby realizing the fixed connection between the co-driver side panel structure and the second bracket 22.

[0058] In this way, when assembling the first bracket 21 and the second bracket 22, there is a certain assembly gap between the first tolerance absorber 2211 and the second tolerance absorber 2221 and the co-driver side panel structure. After the corresponding connecting parts are fixedly installed, the first tolerance absorber 2211 and the second tolerance absorber 2221 can elongate to compensate for the assembly gap, thereby absorbing the tolerance and playing a fastening role.

[0059] The present invention also provides a vehicle including the side panel connection assembly 200 described above.

[0060] In the vehicle of the present invention, its body side panel structure (including the driver side panel structure and the co-driver side panel structure) is connected to the instrument panel reinforcement beam 100 through the side panel connection assembly 200. The first bracket 21 of the side panel connection assembly 200 is connected to the driver side panel structure through the first mounting hole 211, the second mounting hole 212 and the third mounting hole 213. The center point of the first end 11 of the instrument panel reinforcement beam 100 is located within the triangle formed by the first mounting hole 211, the second mounting hole 212 and the third mounting hole 213, thereby strengthening and reinforcing the position where the first end 11 is located and improving the connection stability between the first bracket 21 and the driver side panel structure. The second bracket 22 strengthens and reinforces the upper and lower sides of the second end 12 respectively through the fourth mounting hole 221 and the fifth mounting hole 222, improving the connection stability between the second bracket 22 and the co-driver side panel structure. Compared with the scheme of the side panel connection bracket of the traditional vehicle model that is provided with both X-direction and Y-direction connection structures at the same time, the first mounting hole 211, the second mounting hole 212, the third mounting hole 213, the fourth mounting hole 221 and the fifth mounting hole 222 of the present invention are all Y-direction connection structures, canceling the X-direction connection structure, thereby reducing the overall weight while ensuring that the overall strength and stiffness meet the design requirements.
