Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body structures, and particularly relates to a vehicle body side assembly. In addition, the utility model also relates to a vehicle. Background Art

[0002] Side impact of an automobile is an important index for evaluating the safety performance of a vehicle, mainly for evaluating the protection ability of the vehicle to the personal safety of the occupants during a side impact. The safety performance level of a vehicle has a great influence on the side structure of the vehicle body. It is crucial to design the side structure of the vehicle body in combination with the safety performance.

[0003] In the field of automobile collision testing, the new version of the side impact barrier AC-MDB (Advanced Chinese Mobile Deformable Barrier) has changed compared with the old version. The self-height dimension of the convex part of the barrier has decreased, but the height from the bottom of the convex part of the barrier to the ground has increased, and the self-length dimension and weight of the convex part of the barrier have also increased; the collision energy has increased by about 10%.

[0004] For vehicles with a relatively low vehicle posture in existing vehicle models, when the side impact barrier AC-MDB collides with the side of the vehicle, the impacted part of the vehicle will be higher than the sill beam, resulting in all the collision energy being absorbed by the side structure of the vehicle body such as the side door and the B-pillar. This requires that the overall structural strength of the vehicle body side needs to meet the requirements of the collision test. However, in existing vehicle models, the protection against side impact of the vehicle is mainly achieved by means of the sill beam, and there is a lack of necessary strengthening protection measures for the collision where the collision part is higher than the door frame beam, resulting in the vehicle being difficult to meet the safety requirements when dealing with side impact and its testing. Summary of the Utility Model

[0005] In view of this, the utility model aims to provide a vehicle body side assembly to improve the safety protection performance of the vehicle body side when suffering a collision.

[0006] To achieve the above object, the technical solution of the utility model is realized as follows:

[0007] A vehicle body side assembly includes a side wall frame and a side door disposed in the side wall frame; the B-pillar of the side wall frame includes an outer side wall panel and an inner side wall panel that are fastened together, and a reinforcing plate body is provided in the cavity formed between the outer side wall panel and the inner side wall panel;

[0008] The side door includes an outer door panel and an inner door panel that are fastened together, and an anti-collision beam body is provided in the inner cavity formed between the outer door panel and the inner door panel. The anti-collision beam body is arranged along the front-rear direction of the vehicle and supports the outer door panel.

[0009] Furthermore, the anti-collision beam body includes an outer plate support plate disposed in the middle of the inner cavity, and the front and rear ends of the outer plate support plate are respectively lapped on the front edge plate and the rear edge plate of the inner door panel.

[0010] Furthermore, a front flanging facing the outer door panel is formed at the edge of the front edge plate, and the front part of the outer plate support plate is clamped between the front flanging and the outer door panel; and / or, a rear flanging bent towards the outer door panel is formed at the rear part of the outer plate support plate, and the rear flanging is clamped between the edge part of the rear edge plate and the outer door panel.

[0011] Furthermore, a reinforcing protrusion is formed on the outer plate support plate, and the reinforcing protrusion arches towards the outer door panel.

[0012] Furthermore, the reinforcing protrusion is configured to be strip-shaped arranged along the length direction of the outer plate support plate, and a groove is provided at the top of the reinforcing protrusion, and an expansion glue is filled in the groove.

[0013] Furthermore, the rear end of the outer plate support plate is correspondingly arranged at the door lock installation position, and a door lock reinforcing plate is provided at the door lock installation position. The door lock reinforcing plate is attached to the inner wall of the inner cavity conformally and is connected to both the outer plate support plate and the inner door panel; and / or, an inner plate front reinforcing plate is provided at the front part of the outer plate support plate. The inner plate front reinforcing plate is attached to the inner wall of the inner cavity conformally and is connected to both the outer plate support plate and the inner door panel.

[0014] Furthermore, the anti-collision beam body includes a door anti-collision beam disposed in the lower part of the inner cavity, and the front and rear ends of the outer plate support plate are fixedly installed on the front edge plate and the rear edge plate of the inner door panel through a front fixing plate and a rear fixing plate respectively.

[0015] Furthermore, the cross-section of the outer side panel is configured to be a "ji" shape arched towards the outside of the vehicle; the reinforcing plate body includes a side panel reinforcing plate arranged conformally to the shape of the outer side panel, and the two side edge parts of the side panel reinforcing plate are respectively clamped between the two side edge parts of the outer side panel and the inner side panel.

[0016] Furthermore, the reinforcing plate body further includes a side panel reinforcing plate patch and a B-pillar reinforcing plate patch respectively disposed at the upper and lower parts of the cavity. The side panel reinforcing plate patch and the B-pillar reinforcing plate patch are both attached to the inner wall of the side panel reinforcing plate.

[0017] Compared with the prior art, the present utility model has the following advantages:

[0018] The body side assembly of the present utility model can effectively improve the overall structural strength and anti-impact performance of the B-pillar by arranging a reinforcing plate body in the cavity of the B-pillar; arranging an anti-collision beam body in the inner cavity of the side door can strengthen the structural strength of the side door; when the vehicle is subjected to a side impact, even if the force point of the collision is above the sill beam, it can play a good protective role for the personnel in the cockpit, which is beneficial to improving the safety protection performance of the body side during a collision.

At the front and rear edge parts of the side door, the outer panel of the car door, the outer panel support plate and the inner panel of the door are overlapped and welded together in three layers, which can form a stable support structure.

[0020] Arranging a side wall reinforcing plate in the outer panel of the side wall of the B-pillar, and the cross-sections of the side wall reinforcing plate and the outer panel of the side wall are both in a "J" shape arched towards the outside of the vehicle, which can effectively improve the self-strength and anti-impact property of the B-pillar. Arranging a side wall reinforcing plate patch and a B-pillar reinforcing plate patch on the inner wall of the side wall reinforcing plate facing the inside of the cavity can respectively play a reliable supporting and structural strengthening effect on the upper and lower parts of the side wall reinforcing plate, thereby further improving the structural strength of the B-pillar and its safety protection performance during a side collision of the vehicle.

[0039] The present utility model will be described in detail below with reference to the drawings and in combination with embodiments.

[0040] Embodiment 1

[0041] This embodiment relates to a vehicle body side assembly, which can improve the safety protection performance of the vehicle body side when it is subjected to a collision; an exemplary structure thereof is as Figure 1 and Figure 2 shown.

[0042] Overall, the vehicle body side assembly includes a side frame and side doors disposed in the side frame. Among them, the B-pillar 1 of the side frame includes an outer side panel 10 and an inner side panel 14 that are fastened together, and a reinforcing plate body is provided in the cavity 15 formed between the outer side panel 10 and the inner side panel 14; at the same time, the side door includes an outer door panel and an inner door panel 23 that are fastened together, and an anti-collision beam body is provided in the inner cavity 200 formed between the outer door panel and the inner door panel 23. The anti-collision beam body is arranged in the front-rear direction of the vehicle and supports the outer door panel.

[0043] It should be noted that based on the above overall design concept, the technical solution of the present utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the above side door can be a front door 2 or a rear door 3, and the anti-collision beam body in the side door can be a tubular beam structure or a long strip plate-shaped beam structure. For parts required for the implementation of the overall solution but not involved in the above overall settings, reasonable and flexible designs can be made with reference to mature setting means in the art, actual situations during implementation, etc. The following specific implementation solutions of this embodiment are only one of the better ones among the many solutions that can be formed by the above various combinations and their variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements in combination with the actual situation. Obviously, the many solutions that can be formed by the above various specific form combinations and their variations, as well as the specific implementation solutions of this embodiment, are all within the protection scope of the present utility model.

[0044] For the sake of convenience of description, the above side door is described by taking the front door 2 as an example. As Figures 2 to 6 shown, the anti-collision beam body of this embodiment includes an outer panel support plate 21 disposed in the middle of the inner cavity 200 of the front door 2. The edge part of the inner door panel 23 of the front door has a bent flanging-shaped side plate. Specifically, the inner door panel 23 of this embodiment includes a main body part 230, a front end side plate 231 bent and formed at the front end edge part of the main body part 230, and a front end flanging 232 bent and formed at the rear end edge part of the main body part 230. The front and rear ends of the above outer panel support plate 21 are respectively lapped on the front end side plate 231 and the rear end side plate 233 of the inner door panel 23. Setting the outer panel support plate 21 in the middle position of the inner cavity 200 can play a good supporting role for the outer door panel. When the middle part of the side door is subjected to a collision impact, the outer panel support plate 21 can disperse part of the impact force to the frame position of the side door and absorb the impact energy through deformation, thereby improving the safety protection of the side door.

[0045] For the specific structural settings at the front and rear ends of the outer panel support plate 21 and the connection method with the inner door panel 23, of course, there are a variety of different structural schemes to choose from. In this embodiment, as Figure 4 and Figure 5As shown in the figure, a front flange 232 facing the vehicle outer panel is formed at the edge of the front side plate 231, and the front end portion of the outer panel support plate 21 is clamped between the front flange 232 and the vehicle outer panel. In addition, a rear flange 213 bent toward the vehicle outer panel side can be formed at the rear end portion of the outer panel support plate 21, and the rear flange 213 is clamped between the edge portion of the rear side plate 233 and the vehicle outer panel.

[0046] Based on the above settings, welding positions 6 can be provided at the front flange 232 and the rear flange 213 to weld and fixedly connect the outer panel support plate 21, the vehicle door inner panel 23, and the vehicle outer panel together. It should be noted that since the front flange 232 is bent into a posture perpendicular to the vehicle Y direction, and the rear flange 213 is bent into a posture nearly perpendicular to the vehicle X direction, in this way, when the outer panel support plate 21 and the vehicle door inner panel 23 are joined and welded, the problem that there may be gaps or interferences at the lap joint at the other end after one end is welded, resulting in the inability to weld, is solved; during welding, the welding of the front end of the outer panel support plate 21 and the front flange 232 of the vehicle door inner panel 23 can be carried out in the vehicle Y direction, and the welding between the rear flange 213 at the rear end of the outer panel support plate 21 and the rear side plate 233 can be carried out in the vehicle X direction, making the welding process smoother and facilitating operation and implementation.

[0047] By providing a front flange 232 at the edge of the front side plate 231 of the vehicle door inner panel 23 and a rear flange 213 at the rear end portion of the outer panel support plate 21, the connection between the end portion of the outer panel support plate 21 and the vehicle door inner panel 23 and the vehicle outer panel can be better realized. At the front and rear edge portions of the side vehicle door, the vehicle outer panel, the outer panel support plate 21, and the vehicle door inner panel 23 are overlapped and welded together to form a stable support structure.

[0048] In addition, as Figure 3 shown, a reinforcing protrusion 210 is formed on the outer panel support plate 21 of this embodiment, and the reinforcing protrusion 210 is arched toward the vehicle outer panel side. Preferably, the reinforcing protrusion 210 is configured as a long strip arranged along the length direction of the outer panel support plate 21, and a groove 211 is provided at the top of the reinforcing protrusion 210, and an expansion adhesive 212 is filled in the groove 211. It should be noted that multiple reinforcing protrusions 210 can be provided, grooves 211 can be provided at the tops of each reinforcing protrusion 210, or grooves 211 can be provided only on one or some of the reinforcing protrusions 210. Two reinforcing protrusions 210 are arranged at intervals on the outer panel support plate 21 of this embodiment, and the cross-sectional shape of the outer panel support plate 21 is approximately in an "M" shape. There are not less than ten grooves 211 arranged at intervals on one of the reinforcing protrusions 210, and each groove 211 is filled with the expansion adhesive 212, which ensures the connection reliability between the outer panel support plate 21 and the vehicle outer panel.

[0049] An arched reinforcing protrusion 210 is provided on the outer panel support plate 21, which can improve the structural performance of the outer panel support plate 21 and effectively enhance the supporting effect on the vehicle door outer panel. The reinforcing protrusion 210 is configured as a long strip, which can play a role in strengthening the structure of the outer panel support plate 21 throughout the entire length of the outer panel support plate 21; a groove 211 is provided at the top of the reinforcing protrusion 210, and the expansion glue 212 filled in the groove 211 can bond the vehicle door outer panel to the outer panel support plate 21, preventing abnormal noises from being generated due to vibration and collision between the vehicle door outer panel and the outer panel support plate 21, and can also play a certain buffering effect between the outer panel support plate 21 and the vehicle door outer panel.

[0050] For the material of the outer panel support plate 21, there are various choices, and different steel plates can be used for stamping. In this embodiment, a steel plate of CR1200 / 2000HS+AS40 material is selected, and the material thickness is set at about 1.8 mm and hot-pressed.

[0051] Still as Figure 4 And Figure 5 As shown, the rear end of the outer panel support plate 21 in this embodiment corresponds to the door lock installation position 4, and a door lock reinforcement plate 25 is provided at the door lock installation position 4. The door lock reinforcement plate 25 is attached to the inner wall of the inner cavity 200 conformally and is connected to both the outer panel support plate 21 and the vehicle door inner panel 23. In addition, an inner panel front reinforcement plate 24 can be provided at the front end of the outer panel support plate 21. The inner panel front reinforcement plate 24 is attached to the inner wall of the inner cavity 200 conformally and is connected to both the outer panel support plate 21 and the vehicle door inner panel 23.

[0052] The rear end of the outer panel support plate 21 is arranged at the position where the door lock installation position 4 is located. The door lock reinforcement plate 25 not only provides a reliable installation foundation for the installation of the door lock, but also can further enhance the connection structure strength between the rear end of the outer panel support plate 21, the vehicle door outer panel and the vehicle door inner panel 23. At the same time, the bent flanging design form of the door lock reinforcement plate 25 can be connected to the outer panel support plate 21 and the vehicle door inner panel 23 through welding points to effectively resist the impact force of collision, reduce the deformation degree of the outer panel support plate 21, thereby protecting the door lock and preventing the vehicle door from not being able to be opened after the door lock is damaged, which affects the personal safety of passengers.

[0053] Similarly, setting the inner panel front reinforcement plate 24 at the front end of the outer panel support plate 21 has a good strengthening and supporting effect on the connection structure between the front end of the outer panel support plate 21, the vehicle door outer panel and the vehicle door inner panel 23.

[0054] In addition, as Figure 6As shown in the figure, the anti-collision beam body of this embodiment further includes a door anti-collision beam 22 disposed at the lower part of the inner cavity 200. The front and rear ends of the outer panel support plate 21 are respectively fixedly installed on the front edge plate 231 and the rear edge plate 233 of the door inner panel 23 through a front end fixing plate 220 and a rear end fixing plate 222. To further improve the installation firmness of the door anti-collision beam 22, two middle fixing plates 221 can also be provided in the middle of the door anti-collision beam 22, and the middle fixing plates 221 connected to the door inner panel 23 are used to support the middle of the door anti-collision beam 22, and further improve the anti-impact ability of the door anti-collision beam 22. The above-mentioned door anti-collision beam 22 is preferably made of BR1500HS hot-formed steel and is constructed as a tubular beam structure with a wall thickness of about 3 mm. The door anti-collision beam 22 is fixedly connected to the rear end fixing plate 222, the front end fixing plate 220 and the middle fixing plates 221 by the CO2 shielded welding process, and then spot-welded to the door inner panel 23. Finally, the two middle fixing plates 221 are bonded to the vehicle outer panel through shock-absorbing expansion glue.

[0055] By arranging the door anti-collision beam 22 at the lower part of the inner cavity 200, a significant improvement effect can be achieved on the impact resistance of the lower part of the side door. In this way, the sill beam 5, the door anti-collision beam 22 and the outer panel support plate 21 are arranged one by one from bottom to top, forming a three-dimensional protection for the side of the vehicle, and the purpose of comprehensively improving the anti-collision safety protection performance of the vehicle body side can be achieved.

[0056] As Figure 7 and Figure 8 , Figure 9 As shown in the figure, the cross-section of the outer side panel 10 of this embodiment is constructed as a "ji" shape arched towards the outside of the vehicle; the above-mentioned reinforcing plate body includes a side panel reinforcing plate 11 arranged in accordance with the shape of the outer side panel 10, and the two side edge parts of the side panel reinforcing plate 11 are respectively clamped between the two side edge parts of the outer side panel 10 and the inner side panel 14. By arranging the side panel reinforcing plate 11 in the outer side panel 10 of the B-pillar 1, and the cross-sections of the side panel reinforcing plate 11 and the outer side panel 10 are both in the "ji" shape arched towards the outside of the vehicle, the self-strength and anti-impact performance of the B-pillar 1 can be effectively improved.

[0057] In addition, the types and quantities of the above-mentioned reinforcing plate bodies can be increased. Specifically, the reinforcing plate body of this embodiment further includes a side panel reinforcing plate patch 13 and a B-pillar reinforcing plate patch 12 respectively disposed at the upper and lower parts of the cavity 15. The side panel reinforcing plate patch 13 and the B-pillar reinforcing plate patch 12 are both attached to the inner wall of the side panel reinforcing plate 11. By arranging the side panel reinforcing plate patch 13 and the B-pillar reinforcing plate patch 12 on the inner wall of the side panel reinforcing plate 11 facing the inside of the cavity 15, reliable support and structural strengthening effects can be respectively achieved on the upper and lower parts of the side panel reinforcing plate 11, thereby further improving the structural strength of the B-pillar 1 and the safety protection performance during the side collision of the vehicle.

[0058] For the materials of the above-mentioned side wall reinforcement plate 11, B-pillar reinforcement plate patch 12 and side wall reinforcement plate patch 13, there are, of course, various choices. Preferably, the B-pillar reinforcement plate patch 12 of this embodiment is made of HC340 / 590DP high-strength plate with a thickness of 1.4 mm, and is made into a U-shaped structure. Three welding positions 6 are respectively arranged on two side surfaces and the bottom surface, and are welded and fixedly connected to the side wall reinforcement plate 11. The side wall reinforcement plate patch 13 is made of 22MnB5+AS40 hot-formed steel plate with a thickness of 1.8 mm. The strength of the hot-formed steel plate is superior to that of the high-strength plate, which can further improve the impact resistance of the upper part of the B-pillar 1; the cross-section of the side wall reinforcement plate patch 13 is also made into a U-shaped structure. Three welding positions 6 are respectively arranged on two side surfaces and the bottom surface, and are welded and fixedly connected to the side wall reinforcement plate 11. At the same time, the bottom of the side wall reinforcement plate patch 13 is connected to the B-pillar reinforcement plate patch 12 to improve the overall strength of the B-pillar 1.

[0059] In summary, for the body side assembly of this embodiment, by arranging a reinforcement plate body in the cavity 15 of the B-pillar 1, the overall structural strength and impact resistance of the B-pillar 1 can be effectively improved; by arranging an anti-collision beam body in the inner cavity 200 of the side door, the structural strength of the side door can be enhanced; when the vehicle is subjected to a side impact, even if the force point of the collision is above the sill beam 5, it can play a good protective role for the personnel in the cockpit, which is beneficial to improving the safety protection performance of the body side when suffering from a collision.
