Description

Technical Field

[0001] The present invention relates to the technical field of automobiles, and particularly to a body side structure and a vehicle. Background Art

[0002] Chinese Patent Invention No. CN118219790A discloses a front triangular window structure, a body structure assembly and a vehicle, and its triangular window area adopts a double A-pillar structure. The front triangular window structure includes: a first sub-A pillar, a second sub-A pillar and an A-pillar reinforcement plate that jointly enclose the front triangular window area; an A-pillar lower reinforcement plate vertically connected to one end of the A-pillar reinforcement plate close to the rear of the vehicle; a force transmission beam disposed at one end of the A-pillar reinforcement plate away from the rear of the vehicle; wherein, the force transmission beam has a first force transmission arm and a second force transmission arm; the first force transmission arm is connected to one end of the A-pillar reinforcement plate and / or the first sub-A pillar; the second force transmission arm is connected to one side of the A-pillar lower reinforcement plate close to the sill reinforcement plate. The first sub-A pillar includes a reinforced front section at the front end and a reinforced rear section at the rear end; the first sub-A pillar is connected to the first force transmission arm through the reinforced front section, and is connected to the second sub-A pillar and the A-pillar through the reinforced rear section.

[0003] When the vehicle body is undergoing an SOB collision test, the first force transmission arm in the force transmission beam can transmit the collision impact load to the first sub-A pillar and the A-pillar reinforcement plate respectively; the second force transmission arm can share and transmit the collision impact load to the A-pillar lower reinforcement plate. The first sub-A pillar and the A-pillar reinforcement plate are not only for forming the front triangular window, but can also participate in transmitting, absorbing and buffering the collision force.

[0004] The defects of the above technical solution are as follows:

[0005] During a collision, the force transmission beam will directly transmit the collision force to the first sub-A pillar, the A-pillar reinforcement plate and the A-pillar lower reinforcement plate, and then the first sub-A pillar, the A-pillar reinforcement plate, etc. will transmit, absorb and buffer the collision force. There is no process of buffering the collision force before the collision force is transmitted to the first sub-A pillar, the A-pillar reinforcement plate and the A-pillar lower reinforcement plate. The direct transmission of the collision force will cause a large amount of rearward displacement of the A-pillar lower reinforcement plate (front pillar of the vehicle) and the second sub-A pillar, and the rearward intrusion amount cannot be effectively suppressed.

[0050] The following further describes the detailed embodiment of the present invention with reference to the drawings. The same components are denoted by the same reference numerals. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0051] As Figures 1-5 and Figure 14 shown, a body side structure provided by an embodiment of the present invention includes an A-pillar upper side beam 1 having a lower extension column 12, a front pillar 2 connected to the lower side of the lower extension column 12 and the A-pillar upper side beam 1 and enclosing a triangular window 13, a hood side beam 3 connected to the upper end of the front pillar 2 on the front side, and a hinge 4 provided on the hood side beam 3.

[0052] The front pillar 2 includes a pillar outer panel 21, a pillar inner panel 22, and an intermediate reinforcement plate 23. The intermediate reinforcement plate 23 is fixedly connected to the inner surface of the pillar outer panel 21, and a receiving cavity 24 is formed between the intermediate reinforcement plate 23 and the pillar inner panel 22. The edge of the pillar outer panel 21 is connected to the edge of the pillar inner panel 22.

[0053] The rear end of the hood side beam 3 is respectively connected to the pillar outer panel 21 and the pillar inner panel 22 and faces the receiving cavity 24. The rear end of the hinge 4 faces the receiving cavity 24.

[0054] Wherein, when the hood side beam 3 undergoes a collision and collapses, a part of the deformed hood side beam 3 and at least a part of the hinge 4 enter the receiving cavity 24.

[0055] The body side structure provided by the present invention includes an A-pillar upper side beam 1, a front pillar 2, a hood side beam 3, and a hinge 4.

[0056] The A-pillar upper side beam 1 is a part extending from the rear to the front on the roof. The rear end of the A-pillar upper side beam 1 is connected to the upper end of the intermediate pillar 6 (B-pillar). The front end of the A-pillar upper side beam 1 is connected to the upper end of the front pillar 2. The lower end of the front pillar 2 is connected to the sill beam 5, thereby forming a side frame structure.

[0057] Below the upper side beam 1 of the A-pillar near the front end, there is a downward extension column 12 which extends obliquely downward and is connected to the front pillar 2. The part of the upper side beam 1 of the A-pillar in front of the downward extension column 12 is called the front end part 11 of the upper side beam 1 of the A-pillar, and the front end part 11 and the downward extension column 12 form a double A-pillar structure. With such a setting, a triangular window 13 is formed among the front end part 11 of the upper side beam 1 of the A-pillar, the downward extension column 12 and the front pillar 2.

[0058] The rear end part of the hood side beam 3 is connected to the upper end part of the front pillar 2. The hood side beam 3 is the side beam of the front cover of the vehicle, and the front cover of the vehicle can be the top cover of the engine compartment or the top cover of the motor compartment.

[0059] The hinge 4 is connected above the rear end part of the hood side beam 3, and the rear end 41 of the hinge 4 faces the storage cavity 24. The hinge 4 is used to connect the hood side beam 3 and the hood cover plate.

[0060] In the present invention, the front pillar 2 is composed of a pillar outer plate 21, a pillar inner plate 22 and an intermediate reinforcement plate 23. The intermediate reinforcement plate 23 is fixedly installed on the inner surface of the pillar outer plate 21, and the middle and lower parts of the intermediate reinforcement plate 23 are connected to the pillar inner plate 22 through a connecting member, so that a storage cavity 24 is formed between the intermediate reinforcement plate 23 and the pillar inner plate 22. The edges of the pillar outer plate 21 and the pillar inner plate 22 are welded.

[0061] The rear end of the hood side beam 3 is respectively connected to the pillar outer plate 21 and the pillar inner plate 22, and the rear end of the hood side beam 3 faces the storage cavity 24. The pillar outer plate 21 is a thin plate or a thin sheet. When a collision occurs, the rear end of the hood side beam 3 and the rear end 41 of the hinge 4 can both tear or penetrate through the part where they are connected to the pillar outer plate 21. The intermediate reinforcement plate 23 and the pillar outer plate 21 are multi-point welded, and the connection firmness between the two is good. When the rear end of the hood side beam 3 and the rear end of the hinge 4 tear or penetrate through the pillar outer plate 21, the intermediate reinforcement plate 23 will not be separated from the pillar outer plate 21 but remain together.

[0062] The front side contour of the pillar outer plate 21 is on the front side of the storage cavity 24 and also on the front side of the intermediate reinforcement plate 23. The rear end of the hood side beam 3 is connected to the front side contour of the pillar outer plate 21, and the rear end of the hinge 4 is at the front side contour of the pillar outer plate 21. When the rear end of the hood side beam 3 and the rear end of the hinge 4 tear or penetrate through the front side contour of the pillar outer plate 21, it will basically not affect the intermediate reinforcement plate 23.

[0063] According to needs, the rear end 41 of the hinge 4 can be set to have a pointed structure so as to tear the part where it contacts the pillar outer plate 21.

[0064] Thus, when the hood side beam 3 undergoes a collision and collapses, a part of the deformed hood side beam 3 and at least part of the hinge 4 enter the receiving cavity 24. Although the hinge 4 does not collapse and deform, it will rotate to a certain extent in the receiving cavity 24, reducing the amount of intrusion backward.

[0065] In the present invention, by providing the receiving cavity 24 to accommodate the hood side beam 3 that undergoes a collision and collapses and the hinge 4 that enters along with the hood side beam 3, it is possible to avoid a rigid impact on the front end portion 11 of the upper side beam 1 of the rear A-pillar and the front pillar 2, play a role in buffering the collision force, effectively inhibit the amount of rearward intrusion of the front pillar 2 and the lower extension pillar 12, and improve the safety performance of the product.

[0066] In one embodiment, as Figures 1-3 shown, the front end portion 11 of the A-pillar upper side beam 1 is divided into an outer front end plate 111 and an inner front end plate 112. The lower extension pillar 12 is divided into an outer extension pillar plate 121 and an inner extension pillar plate 122. The triangular window 13 is divided into an outer triangular window 131 and an inner triangular window 132.

[0067] The outer front end plate 111 is integrally provided at the top of the pillar outer plate 21 and extends obliquely upward and backward. The outer extension pillar plate 121 is integrally connected between the rear end of the outer front end plate 111 and the rear side edge of the pillar outer plate 21. The outer triangular window 131 is formed between the pillar outer plate 21, the outer extension pillar plate 121 and the outer front end plate 111.

[0068] The inner front end plate 112 is integrally provided at the top of the pillar inner plate 22 and extends obliquely upward and backward. The inner extension pillar plate 122 is integrally connected between the rear end of the inner front end plate 112 and the rear side edge of the pillar inner plate 22. The inner triangular window 132 is formed between the pillar inner plate 22, the inner extension pillar plate 122 and the inner front end plate 112.

[0069] During assembly, the pillar outer plate 21 and the pillar inner plate 22 are welded along the peripheral edge, the outer front end plate 111 covers the inner front end plate 112 and is welded, the outer extension pillar plate 121 and the inner extension pillar plate 122 are welded, and the outer triangular window 131 and the inner triangular window 132 are butted to form the triangular window 13.

[0070] In one embodiment, as Figures 4-5 and Figures 9-10 shown, the middle reinforcing plate 23 includes a U-shaped reinforcing plate main body 231 and an extension plate 232 provided above the reinforcing plate main body 231.

[0071] The receiving cavity 24 is formed between the extension plate 232 and the pillar inner plate 22.

[0072] A preset distance is left between the extension plate 232 and the front edge of the reinforcing plate main body 231, and a notch 233 for avoiding the hood side beam 3 and the hinge 4 is formed.

[0073] In this embodiment, the middle reinforcing plate 23 is composed of a reinforcing plate main body 231 and an extension plate 232. The reinforcing plate main body 231 is generally U-shaped, with the opening of the U-shaped facing the inner column plate 22, and the reinforcing plate main body 231 is connected to the outer column plate 21.

[0074] The length of the reinforcing plate main body 231 along the front-rear direction is greater than the length of the extension plate 232. The extension plate 232 is integrally provided at the top of the reinforcing plate main body 231, and the front edge of the extension plate 232 is at a distance from the front edge of the reinforcing plate main body 231, thereby forming a notch 233. This notch 233 is used to avoid the hood side beam 3 and the hinge 4, so that the hood side beam 3 after collapse and the hinge 4 that moves backward subsequently can enter the storage cavity 24. The extension plate 232 is connected to the outer column plate 21 to maintain the reliability of its connection with the outer column plate 21.

[0075] In one embodiment, the reinforcing plate main body 231 and the extension plate 232 are respectively welded to the outer column plate 21. Specifically, the reinforcing plate main body 231, the extension plate 232 and the outer column plate 21 are respectively welded at multiple points to improve the firmness of the connection structure.

[0076] In one embodiment, as Figure 10 shown, a connection bracket 234 is provided on the inner side of the reinforcing plate main body 231, and the connection bracket 234 is connected to the inner column plate 22. The connection bracket 234 can be welded to the inner column plate 22, or can be connected by rivets or pins.

[0077] In one embodiment, as Figure 13 shown, a guiding structure 235 for guiding the hood side beam 3 and / or the hinge 4 to move toward the inner column plate 22 side is provided on the inner side of the extension plate 232, so as to prevent the hood side beam 3 and / or the hinge 4 entering the storage cavity 24 from tearing the extension plate 232 and affecting the collapse energy absorption and buffering effect.

[0078] In one embodiment, as Figure 13 shown, the guiding structure 235 includes a guiding diagonal rib 2351, and in the direction from front to back, the guiding diagonal rib 2351 gradually extends obliquely toward the inner column plate 22 side.

[0079] In this embodiment, the guiding structure 235 adopts a guiding diagonal rib 2351, which is provided on the inner surface of the extension plate 232. The front end of the guiding diagonal rib 2351 is connected to the front edge of the extension plate 232 and extends gradually from front to back toward the middle of the storage cavity 24, so as to guide the hood side beam 3 and / or the hinge 4 to enter the middle position of the storage cavity 24.

[0080] In one embodiment, as Figures 4-5 and Figures 11-12 shown, the hood side beam 3 includes a side beam bottom plate 31, a side beam top plate 32, and a side beam outer plate 33 connected between the outer edges of the side beam bottom plate 31 and the side beam top plate 32.

[0081] Connecting flanges 34 are respectively provided at the inner edges of the side beam bottom plate 31 and the side beam top plate 32, and the connecting flanges 34 are respectively connected to one side of the inner column plate 22 facing the receiving cavity 24.

[0082] The rear ends of the side beam outer plate 33 and the side beam bottom plate 31 are respectively connected to the outer column plate 21 and are located on the front side of the extension plate 232.

[0083] In the width direction of the front column 2, the rear end of the side beam outer plate 33 is located inside the extension plate 232.

[0084] In this embodiment, the hood side beam 3 is integrally U-shaped with its opening facing inward. The hood side beam 3 is integrally formed by the side beam bottom plate 31, the side beam top plate 32, and the side beam outer plate 33. A connecting flange 34 extending downward is provided at the inner edge of the side beam bottom plate 31, and a connecting flange 34 extending upward is provided at the inner edge of the side beam top plate 32. The vertically arranged connecting flanges 34 are respectively connected to one side of the inner column plate 22 facing the receiving cavity 24. Specifically, a nose bridge plate 221 is provided on the front side of the inner column plate 22, and the vertically arranged connecting flanges 34 are respectively connected to the nose bridge plate 221.

[0085] The rear ends of the side beam outer plate 33 and the side beam bottom plate 31 are respectively connected to the front contour of the outer column plate 21, and the rear ends of the side beam outer plate 33 and the side beam bottom plate 31 are both located on the front side of the extension plate 232 and the notch 233. In the width direction of the front column 2, the rear end of the side beam outer plate 33 is located inside the extension plate 232, and the outer edge of the rear end contour of the side beam bottom plate 31 is also located inside the extension plate 232. Thus, when a collision occurs and the structure collapses, the rear ends of the side beam outer plate 33 and the side beam bottom plate 31 can smoothly enter the receiving cavity 24.

[0086] In one embodiment, as Figure 2 , Figure 8 and Figures 11-12 shown, the front side of the outer column plate 21 has a guiding step 212.

[0087] At least one outer plate connecting insert 331 is provided at the rear end of the side beam outer plate 33, and a bottom plate connecting insert 311 is provided at the rear end of the side beam bottom plate 31.

[0088] The bottom plate connecting insert 311 is located below the outer plate connecting insert 331 and is arranged in parallel with the outer plate connecting insert 331.

[0089] The outer panel connecting insert 331 and the bottom panel connecting insert 311 are respectively connected to the guiding step 212.

[0090] During a collision, the outer panel connecting insert 331 and the bottom panel connecting insert 311 can respectively pierce through the guiding step 212.

[0091] In this embodiment, the front side profile of the pillar outer panel 21 has a flanging 211 that bends inward, and a plurality of concave guiding steps 212 are provided at the front side edge of the pillar outer panel 21 for installing the outer panel connecting insert 331 at the rear end of the side beam outer panel 33 and the bottom panel connecting insert 311 at the rear end of the side beam bottom panel 31.

[0092] Among them, a plurality of outer panel connecting inserts 331 are provided at the rear end of the side beam outer panel 33 at intervals in the vertical direction. The outer panel connecting inserts 331 are arranged substantially vertically and can be attached to the plane of the guiding step 212. A bottom panel connecting insert 311 is provided at the rear end of the side beam bottom panel 31. The bottom panel connecting insert 311 is integrally connected to the rear end of the side beam bottom panel 31 through an extension piece. The bottom panel connecting insert 311 is generally located below the outer panel connecting insert 331 and also adopts a substantially vertical arrangement method so as to be attached to the plane of the guiding step 212.

[0093] When the hood side beam 3 is crushed, both the bottom panel connecting insert 311 and the outer panel connecting insert 331 can pierce or tear the step surface of the guiding step 212, and the hood side beam 3 and the hinge 4 moving backward will also crush the flanging 211, resulting in good buffering effect.

[0094] In one of the embodiments, as Figure 1 、 Figure 3 and Figures 6-7 shown, the body side structure includes a sill beam 5, and the front end of the sill beam 5 is connected below the front pillar 2.

[0095] An upper side beam reinforcement plate 14 is provided in the A-pillar upper side beam 1, and the front end 141 of the upper side beam reinforcement plate 14 is flush with the front end of the sill beam 5.

[0096] With such a setting, the front end 141 of the upper side beam reinforcement plate 14 will not exceed the front end of the sill beam 5. Compared with the conventional design where the entire A-pillar needs to be strengthened, the length of the upper side beam reinforcement plate 14 is shortened in the present invention, which is beneficial to cost reduction. On the other hand, since the front end 141 of the upper side beam reinforcement plate 14 is not connected to the nose plate 221 of the inner pillar panel 22, it will not collide with the hood side beam 3. After the hood side beam 3 collapses, it enters the storage cavity 24 and basically will not have a rigid collision with the upper side beam reinforcement plate 14, so it will not transmit force rigidly to the upper side beam reinforcement plate 14. During a collision, the part of the inner pillar panel 22 in front of the front end 141 of the upper side beam reinforcement plate 14 will not be affected by the rigid upper side beam reinforcement plate 14, and this part can deform and collapse, cutting off or slowing down the collision force transmitted backward, further improving the buffering and energy absorption effects.

[0098] According to needs, the above technical solutions can be combined to achieve the best technical effects.

[0099] The above are only the principles and preferred embodiments of the present invention.
