[0046] The existing body A-pillar structure includes an engine compartment A-pillar located on the engine compartment assembly and a side panel A-pillar located on the side panel assembly.

[0047] The existing connection method between the engine compartment A-pillar and the side panel A-pillar is to connect them by resistance spot welding.

[0048] The connection strength between the engine compartment A-pillar and the sidewall A-pillar connected by resistance spot welding is low. As the vehicle weight increases, during a vehicle collision, the solder joints on the engine compartment A-pillar and the sidewall A-pillar are prone to tearing, causing the engine compartment A-pillar and the sidewall A-pillar to be easily separated and fractured, and easily resulting in deformation and damage of the cab.

[0049] To solve the technical problem of the low connection strength between the existing engine compartment A-pillar and the sidewall A-pillar, the present application proposes a strengthened connection structure for the vehicle body A-pillar, a vehicle body A-pillar structure, and a vehicle.

One end of the connecting member is used to be arranged on the sidewall A-pillar of the vehicle body A-pillar, and the other end of the connecting member is arranged in the mounting hole. The connecting member is used to connect the sidewall A-pillar and the engine compartment A-pillar.

[0050] The strengthened connection structure for the vehicle body A-pillar of the present application strengthens the connection between the sidewall A-pillar and the engine compartment A-pillar by arranging a mounting seat on the engine compartment A-pillar, then arranging one end of the connecting member on the sidewall A-pillar and the other end of the connecting member in the mounting hole. Compared with the existing connection between the engine compartment A-pillar and the sidewall A-pillar only by resistance spot welding, by setting the strengthened connection structure for the vehicle body A-pillar of the present application, the connection strength between the engine compartment A-pillar and the sidewall A-pillar is improved, the connection solder joints on the engine compartment A-pillar and the sidewall A-pillar can be prevented from tearing, thereby improving the strength of the entire vehicle body A-pillar structure, additionally improving the connection performance of the vehicle body on the basis of ensuring the original connection ability, and also improving the bending and compressive resistance of the vehicle body A-pillar structure in multiple directions, thus overall improving the performance of the vehicle body A-pillar structure.

[0051] The following specifically describes the technical solution of the application in conjunction with the accompanying drawings. These several specific embodiments below can be combined with each other, and for the same or similar concepts or processes, they may not be repeated in some embodiments.

[0055] In the embodiment of the present application, with reference to Figure 1 As shown, the embodiment of the present application provides a body A-pillar strengthening connection structure, including a mounting seat 200 and a connecting member 300.

[0056] The mounting seat 200 is used to be arranged on the engine compartment A-pillar 110 of the body A-pillar 100. The mounting seat 200 is provided with a mounting hole 210. One end of the connecting member 300 is used to be arranged on the side A-pillar 120 of the body A-pillar 100, and the other end of the connecting member 300 is arranged in the mounting hole 210. The connecting member 300 is used to connect the side A-pillar 120 and the engine compartment A-pillar 110.

[0057] The mounting seat 200 is arranged on the engine compartment A-pillar 110 of the body A-pillar 100. The setting method can be welding, clamping, bolt connection, etc., or integrally formed with the engine compartment A-pillar 110.

[0058] The connecting member 300 can be a connecting rod, a connecting plate, a connecting buckle, etc. One end of the connecting member 300 is arranged on the side A-pillar 120 of the body A-pillar 100. The setting method can be detachable connection or fixed connection, such as bolt connection, clamping, etc.

[0059] The other end of the connecting member 300 is arranged in the mounting hole 210. Similarly, the setting method can be detachable connection or fixed connection, such as bolt connection, clamping, etc.

[0060] The strengthened connection structure of the vehicle body A-pillar in this application strengthens the connection between the side A-pillar 120 and the engine compartment A-pillar 110 by setting an installation seat 200 on the engine compartment A-pillar 110, then setting one end of the connecting member 300 on the side A-pillar 120, and setting the other end of the connecting member 300 in the installation hole 210. Compared with the existing method of only connecting the engine compartment A-pillar 110 and the side A-pillar 120 by resistance spot welding, by setting the strengthened connection structure of the vehicle body A-pillar in this application, the connection strength between the engine compartment A-pillar 110 and the side A-pillar 120 is improved, the connection solder joints on the engine compartment A-pillar 110 and the side A-pillar 120 can be prevented from tearing, thereby improving the strength of the entire vehicle body A-pillar structure. On the basis of ensuring the original connection ability, the connection performance of the vehicle body 900 is additionally improved, and the bending and compressive resistance abilities of the vehicle body A-pillar structure in multiple directions are also improved, thereby improving the performance of the vehicle body A-pillar structure as a whole.

[0061] In other embodiments, one end of the connecting member 300 is detachably connected to the side A-pillar 120, and the connecting member 300 is detachably connected to the installation seat 200 through the installation hole 210.

[0062] In this embodiment, since the connecting member 300 is detachably connected to the side A-pillar 120 and the installation hole 210 respectively, the installation and disassembly efficiency of the worker is improved, it is convenient for the worker to replace and repair the connecting member 300, and connecting members 300 with different strengths can be installed according to different strength requirements.

[0063] In another embodiment, the connecting member 300 is a connecting bolt, the installation hole 210 is a threaded hole, one end of the connecting bolt is used to be set on the side A-pillar 120, and the other end of the connecting bolt is threadedly connected in the threaded hole.

[0064] In this embodiment, by setting the connecting member 300 as a connecting bolt, the installation and disassembly efficiency of the connecting member 300 is improved, and the connection strength is ensured, so that the bending and compressive resistance abilities of the vehicle body A-pillar 100 in the X and Z directions of the vehicle are improved.

[0065] Among them, the connecting bolt can adopt an M14 bolt.

[0066] Furthermore, the installation seat 200 can be a nut bushing; through the mating connection of the connecting bolt and the nut bushing, the strengthened connection between the side A-pillar 120 and the engine compartment A-pillar 110 is realized, thereby ensuring the stability of the connection between the side A-pillar 120 and the engine compartment A-pillar 110 and preventing the solder joints between the side A-pillar 120 and the engine compartment A-pillar 110 from tearing.

[0067] In other embodiments, the nut bushing is perpendicular to the side A-pillar 120 and the engine compartment A-pillar 110 respectively to enhance the stability of the nut bushing fixation and further prevent the nut bushing from falling off.

[0068] Reference Figure 3 , Figure 4 and Figure 5 As shown in Figure 3 , Figure 4 and Figure 5 , a second aspect of the embodiment of the present application provides a vehicle body A-pillar structure, which includes an engine compartment A-pillar 110 and a side wall A-pillar 120 connected to the engine compartment A-pillar 110, and further includes the vehicle body A-pillar strengthening connection structure of any of the above embodiments.

In this embodiment, the mounting seat 200 of the vehicle body A-pillar strengthening connection structure is arranged on the A-pillar strengthening bracket 112, thereby ensuring the stability of the connection of the mounting seat 200, preventing the mounting seat 200 from falling off the engine compartment A-pillar 110, and ensuring the connection strength of the vehicle body A-pillar strengthening connection structure.

[0070] Reference Figure 4 , Figure 5 and Figure 10 As shown in Figure 4 , Figure 5 and Figure 10 , in this embodiment, a receiving groove 1121 matching the mounting seat 200 is provided on the bottom surface of the A-pillar strengthening bracket 112, and the side wall of the mounting seat 200 abuts against the inside of the receiving groove 1121.

[0071] In this embodiment, since the side wall of the mounting seat 200 abuts against the inside of the receiving groove 1121, the contact area between the mounting seat 200 and the A-pillar strengthening bracket 112 is increased, and the stability of the fixation of the mounting seat 200 is further improved.

[0072] The way that the mounting seat 200 abuts against the receiving groove 1121 can be welding, snap connection, bonding, etc. In this embodiment, the mounting seat 200 can be welded in the receiving groove 1121 by carbon dioxide arc welding to ensure the connection strength of the mounting seat 200 and further prevent the mounting seat 200 from falling off the A-pillar strengthening bracket 112.

[0073] Similarly, since the vehicle body A-pillar structure provided by the present application is provided with the vehicle body A-pillar strengthening connection structure of any of the above embodiments, the strength of the vehicle body A-pillar of the present application is improved compared with the existing vehicle body A-pillar structure, the connection welding points on the engine compartment A-pillar 110 and the side wall A-pillar 120 can be prevented from tearing, and the safety performance of the vehicle body A-pillar is improved.

[0074] In a certain embodiment, reference Figure 6 and Figure 7As shown, the sidewall A-pillar 120 includes an outer sidewall A-pillar panel 121 and a sidewall A-pillar reinforcement plate 122. The sidewall A-pillar reinforcement plate 122 is disposed on the outer sidewall A-pillar panel 121, and the sidewall A-pillar reinforcement plate 122 is located between the outer sidewall A-pillar panel 121 and the engine compartment A-pillar 110. The connecting member 300 of the body A-pillar strengthening connection structure is disposed on the sidewall A-pillar reinforcement plate 122.

[0075] The connecting member 300 of the body A-pillar strengthening connection structure can be disposed at any position of the sidewall A-pillar 120, such as on the outer sidewall A-pillar panel 121 or the sidewall A-pillar reinforcement plate 122; in this embodiment, the connecting member 300 of the body A-pillar strengthening connection structure is disposed on the sidewall A-pillar reinforcement plate 122, thereby ensuring the stability of the connection of the connecting member 300 to the sidewall A-pillar 120, preventing the connecting member 300 from falling off the sidewall A-pillar 120, and ensuring the connection strength of the connecting member 300.

[0076] In some embodiments, a first mounting through-hole 400 is provided on the sidewall A-pillar reinforcement plate 122. The first mounting through-hole 400 is used to connect one end of the connecting member 300 away from the engine compartment A-pillar 110.

[0077] In this embodiment, referring to Figure 2 As shown, by providing the first mounting through-hole 400 on the sidewall A-pillar reinforcement plate 122, the connection of the connecting member 300 is facilitated, so that the connecting member 300 can be disposed on the sidewall A-pillar reinforcement plate 122.

[0078] Furthermore, when the connecting member 300 is a connecting bolt, the nut end of the connecting bolt can abut against the first mounting through-hole 400, thereby facilitating the fixation of the connecting bolt; of course, the connecting member 300 can also be other connecting components, such as a buckle, a hook, etc. The connecting member 300 can be fixed to the first mounting through-hole 400 by snap connection or hanging connection.

[0079] In another possible embodiment, a second mounting through-hole 500 is provided on the outer sidewall A-pillar panel 121. The second mounting through-hole 500 corresponds to the first mounting through-hole 400. The second mounting through-hole 500 is used to allow the connecting member 300 to pass through the outer sidewall A-pillar panel 121 and be connected to the first mounting through-hole 400.

[0080] In this embodiment, referring to Figure 2 As shown, since the outer sidewall A-pillar panel 121 covers the sidewall A-pillar reinforcement plate 122, for the convenience of installation, by providing the second mounting through-hole 500 on the outer sidewall A-pillar panel 121, it is ensured that the connecting member 300 can be led to the sidewall A-pillar reinforcement plate 122, facilitating the installation of the connecting member 300.

[0081] In other possible embodiments, referring to Figure 1As shown, it further includes a sealing plug 700, and the sealing plug 700 covers the second mounting through-hole 500 to seal the second mounting through-hole 500.

[0082] In this embodiment, by providing the sealing plug 700 on the second mounting through-hole 500 to seal the second mounting through-hole 500, water can be prevented from entering the body 900 cavity from the outer panel 121 of the sidewall A-pillar through the second mounting through-hole 500. Moreover, wind noise can be reduced and the risk of rust can be lowered.

[0083] Furthermore, a flanging structure can be provided for the second mounting through-hole 500, as Figure 1 and Figure 2 shown, that is, a flanging structure facing the sidewall A-pillar reinforcement plate 122 is provided around the second mounting through-hole 500, so as to prevent the operator from being cut by the second mounting through-hole 500 when installing the connecting member 300.

[0084] In other embodiments, referring to Figure 2 shown, it further includes a hinge plate 800. The hinge plate 800 is used to connect with the vehicle door. The hinge plate 800 is arranged on the side of the sidewall A-pillar reinforcement plate 122 close to the engine compartment A-pillar 110.
