DETAILED DESCRIPTION

[0046] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.

[0047] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0048] For related technologies, see Figure 1The vehicle body, the front pillar 2 and the front wall panel 3 are arranged to form a car body 31 and an engine compartment 32 located in front of the car body 31. The front wall panel 3 is connected to the lower inner panel 22 of the front pillar, but the reinforcing cross beam 4 installed on the front wall panel 3 is arranged at an interval from the front pillar 2. The reinforcing cross beam 4 and the front pillar 2 are disconnected and not connected together. The force transmission path between the reinforcing cross beam 4 and the front pillar 2 is disconnected. The load on the reinforcing cross beam 4 needs to be indirectly transmitted to the lower inner panel 22 of the front pillar through the front wall panel 3. It is difficult for the reinforcing cross beam 4 to directly transmit the load to the front pillar 2, and it is difficult to play an effective reinforcing role, resulting in low strength and rigidity of the vehicle body assembly. Therefore, the collision performance of the vehicle body assembly is poor.

[0049] In view of this, an embodiment of the present application provides a vehicle, including a body assembly and a vehicle main body, wherein the vehicle main body is installed on the body assembly.

[0050] Exemplarily, the vehicle body may include structures such as an engine, wheels, and a drive axle, etc. The engine drives the wheels to rotate or the engine drives the wheels to rotate through the drive axle, so that the entire vehicle moves.

[0051] The vehicle body assembly in the embodiment of the present application includes a vehicle body and a front pillar 2. The front pillar 2 includes a front pillar outer panel 21, a front pillar lower inner panel 22 and a support member 23. The front pillar outer panel 21 is connected to the vehicle body, the front pillar lower inner panel 22 is located on the inner side of the front pillar outer panel 21, and the support member 23 is located in the space enclosed between the front pillar outer panel 21 and the front pillar lower inner panel 22. The support member 23 is connected to the front pillar outer panel 21 and the front pillar lower inner panel 22. In this structural form, the front pillar 2 is used to support the vehicle body, so that the vehicle body assembly has a certain strength.

[0052] For example, the front pillar lower inner panel 22 may be connected to the vehicle body.

[0053] In one embodiment, please refer to Figure 2 and Figure 3 The vehicle body assembly further includes a front wall panel 3, which, together with the vehicle body and the front pillar 2, is surrounded by a vehicle compartment 31 and an engine compartment 32 located in front of the vehicle compartment 31. In this way, the space in the vehicle body is divided by the front wall panel 3 into the vehicle compartment 31 for passengers and the engine compartment 32 for installing the engine.

[0054] It should be explained that the front pillar 2 is roughly between the engine compartment 32 and the cockpit of the vehicle compartment 31 , and the front pillar 2 is usually called an A-pillar in the automotive field.

[0055] In one embodiment, please refer to Figure 2 , Figure 3 and Fig. 9The vehicle body assembly further includes a reinforcing crossbeam 4, which is mounted on the side of the front wall plate 3 facing the vehicle compartment 31. In this way, the reinforcing crossbeam 4 is used to reinforce the front wall plate 3, which can improve the strength of the front wall plate 3 to a certain extent and increase the deformation resistance of the front wall plate 3.

[0056] In one embodiment, please refer to Figure 2 to Figure 5 The vehicle body assembly further includes a transition piece 5. The transition piece 5 is respectively mounted on the reinforcing cross beam 4 and the lower inner panel 22 of the front pillar. In this way, since the transition piece 5 is respectively mounted on the reinforcing cross beam 4 and the lower inner panel 22 of the front pillar, a force transmission channel between the reinforcing cross beam 4 and the lower inner panel 22 of the front pillar is established through the transition piece 5, and the lower inner panel 22 of the front pillar is supported by the support piece 23. The load borne by the reinforcing cross beam 4 can be transmitted to the lower inner panel 22 of the front pillar through the transition piece 5, and the load transmitted to the lower inner panel 22 of the front pillar can be transmitted to the outer panel 21 of the front pillar through the support piece 23. The stiffness of the outer panel 21 of the front pillar is generally greater than the stiffness of the lower inner panel 22 of the front pillar, and the strength of the outer panel 21 of the front pillar is generally greater than the strength of the lower inner panel 22 of the front pillar. The outer panel 21 of the front pillar is not easily deformed and can bear loads better. Therefore, a force transmission channel is established between the reinforcing crossbeam 4 and the front pillar outer panel 21, and the load of the reinforcing crossbeam 4 can be transmitted to the front pillar outer panel 21 through the transition piece 5, so that the vehicle body can bear the load better, thereby improving the strength and rigidity of the vehicle body assembly, thereby improving the collision performance of the vehicle body assembly.

[0057] In one embodiment, please refer to Figure 2 to Figure 5 The transition piece 5 includes a cross beam adapter 51 and a front pillar adapter 52. The cross beam adapter 51 is installed on the reinforcing cross beam 4. The front pillar adapter 52 is connected to the cross beam adapter 51, and the front pillar adapter 52 is in surface contact with the front pillar lower inner plate 22. In such a structural form, the front pillar adapter 52 is in surface contact with the front pillar lower inner plate 22, and the load of the front pillar adapter 52 clamped by the stopper and the support member 23 can be dispersed and carried by the front pillar lower inner plate 22 as much as possible and transferred to the support member 23, so that the front pillar lower inner plate 22 can better transfer the load of the front pillar adapter 52.

[0058] In one embodiment, please refer to Figure 2 to Figure 4 The front pillar adapter 52 is in the shape of a flat plate. In this way, the flat front pillar adapter 52 can be well fitted with the front pillar lower inner plate 22, which is conducive to better transfer of load to the front pillar lower inner plate 22 through the front pillar adapter 52, and the flat front pillar adapter 52 is conducive to appropriate weight reduction.

[0059] It is understandable that the shape of the front pillar 2 is not limited to a flat plate. The shape of the front pillar 2 only needs to satisfy the surface contact between the front pillar adapter 52 and the front pillar lower inner plate 22.

[0060] It is understandable that the front pillar adapter 52 is not limited to surface contact with the front pillar lower inner plate 22. The front pillar adapter 52 can be arched at the position corresponding to the fastener to be spaced apart from the front pillar lower inner plate 22. The transition piece 5 is respectively installed on the reinforcing cross beam 4 and the front pillar lower inner plate 22 so that the load of the reinforcing cross beam 4 can be transferred to the front pillar outer plate 21.

[0061] In one embodiment, please refer to Figure 4 and Figure 5 The beam adapter 51 includes a first wing plate 511, a first connecting plate 512 and a first mounting plate 513. The first connecting plate 512 is connected to the side of the first wing plate 511 away from the front wall plate 3. The first mounting plate 513 is connected to the first connecting plate 512 and the reinforcing beam 4 respectively. The first mounting plate 513 is located on the side of the first connecting plate 512 away from the first wing plate 511, and the reinforcing beam 4 is located on the side of the first mounting plate 513 facing the front wall plate 3. The arrangement direction of the first mounting plate 513 and the reinforcing beam 4 is a first direction, and the direction intersecting the first direction and the length direction of the reinforcing beam 4 is a second direction. The first connecting plate 512 and the first wing plate 511 are arranged at both ends of the first mounting plate 513 along the second direction, and the first connecting plates 512 at both ends are located between the first wing plates 511 at both ends. With such a structural form, the beam adapter 51 roughly forms an I-shaped structure through the first wing plate 511, the first connecting plate 512 and the first mounting plate 513. A cavity is formed between the I-shaped structure formed by the beam adapter 51 and the front wall plate 3. The I-shaped structure of the beam adapter 51 can increase the strength of the beam adapter 51, which is beneficial to the load transfer of the beam adapter 51. The cavity structure formed between the beam adapter 51 and the front wall plate 3 is beneficial for partially accommodating the reinforcing beam 4 so that the beam adapter 51 can be installed on the reinforcing beam 4, and is also beneficial for reducing the weight of the beam adapter 51.

[0062] For example, see Figure 2 , the first direction is the direction indicated by the arrow R1 in the figure.

[0063] Exemplarily, the first direction is substantially along the length direction of the vehicle body.

[0064] For example, see Figure 2 , the second direction is the direction indicated by arrow R2 in the figure.

[0065] Exemplarily, the second direction is substantially along the height direction of the vehicle body.

[0066] It is understandable that the cross-sectional shape of the crossbeam adapter 51 is not limited to the "X"-shaped structure, and other shapes are also possible.

[0067] In one embodiment, please refer to Figure 4The transition piece 5 further includes a reinforcing rib 53, which is respectively connected to the front pillar adapter 52 and the first mounting plate 513. With such a structural form, the reinforcing rib 53 respectively connected to the front pillar adapter 52 and the first mounting plate 513 can reduce the springback deformation between the front pillar adapter 52 and the first mounting plate 513 after molding, thereby increasing the strength and rigidity of the front pillar adapter 52 and the first mounting plate 513.

[0068] In one embodiment, please refer to Figure 4 There are two front column adapters 52 , both of which are connected to the crossbeam adapter 51 . The two front column adapters 52 are arranged at intervals, and the reinforcing rib 53 is located between the two front column adapters 52 .

[0069] In one embodiment, please refer to Figure 4 The reinforcing rib 53 is in the shape of an arc-shaped plate.

[0070] In one embodiment, please refer to Figure 3 and Figure 4 The reinforcing rib 53 protrudes from the front pillar adapter 52 on the side away from the lower inner plate 22 of the front pillar, and the reinforcing rib 53 protrudes from the first mounting plate 513 on the side away from the front wall plate 3.

[0071] In one embodiment, please refer to Figure 3 , Figure 4 and Fig. 9 , the transition piece 5 is formed with a positioning hole 54, and the reinforcing cross beam 4 includes a beam body 41, a positioning column 42 and a second fastener 43. The beam body 41 is connected to the transition piece 5. The positioning column 42 is connected to the side of the beam body 41 away from the front wall plate 3, and the positioning column 42 is penetrated through the positioning hole 54. The second fastener 43 is installed on the positioning column 42 to partially clamp the transition piece 5 between the second fastener 43 and the beam body 41. In such a structural form, during the installation process, the transition piece 5 can be first sleeved on the positioning column 42 through the positioning hole 54 to achieve the initial positioning of the transition piece 5. The positioning column 42 passes through the positioning hole 54, and the transition piece 5 can be clamped by the second fastener 43 and the reinforcing cross beam 4 at the position corresponding to the positioning column 42 to achieve the installation of the transition piece 5. The transition piece 5 is fastened to the beam body 41 by the second fastener 43 so that the transition piece 5 is installed more firmly, which is conducive to the transition piece 5 to better transmit the load and improve the strength and rigidity of the vehicle body assembly.

[0072] In one embodiment, the second fastener 43 may be a second nut that is threadedly connected to the positioning column 42 .

[0073] It can be understood that the support member 23 is located in the space enclosed between the front pillar outer panel 21 and the front pillar lower inner panel 22. Since the space enclosed between the front pillar outer panel 21 and the front pillar 2 inner panel is relatively narrow or even relatively closed, it is difficult for a welding gun or welding rod to extend into the space between the front pillar outer panel 21 and the front pillar lower inner panel 22 to weld the support member 23. The front pillar outer panel 21 and the front pillar lower inner panel 22 are difficult to be connected to the support member 23 by welding. When the support member 23 is welded to the front pillar outer panel 21, it is necessary to weld the support member 23 to the front pillar outer panel 21 before the front pillar lower inner panel 22 is covered on the front pillar outer panel 21, and then the front pillar lower inner panel 22 is covered on the front pillar outer panel 21 so that the support member 23 is located in the space between the front pillar lower inner panel 22 and the front pillar outer panel 21. Since the space between the front pillar lower inner panel 22 and the front pillar outer panel 21 is narrow or even closed, it is difficult to weld the support member 23. Therefore, when the support member 23 is welded to the front pillar outer panel 21, it is almost impossible to weld the support member 23 and the front pillar lower inner panel 22.

[0074] In one embodiment, please refer to Figure 2 to Figure 8 , the support member 23 is welded to the front pillar outer panel 21, the vehicle body assembly further includes a first fastener 6, the first fastener 6 includes a connecting portion and a stopper portion connected to each other, the connecting portion passes through the transition member 5 and the front pillar lower inner panel 22, the connecting portion is connected to the support member 23, and the front pillar lower inner panel 22 and the transition member 5 are both clamped between the support member 23 and the stopper portion. With such a structural form, the welding of the support member 23 and the front pillar outer panel 21 has little effect on the appearance quality of the outer side of the front pillar outer panel 21 away from the support member 23, and the outer side of the front pillar outer panel 21 away from the support member 23 can still basically maintain a good appearance quality. The first fastener 6 is used to fasten the transition piece 5, the lower inner panel 22 of the front pillar and the support piece 23. The connection portion of the first fastener 6 is connected to the support piece 23, and the lower inner panel 22 of the front pillar and the transition piece 5 are clamped between the support piece 23 and the stopper, thereby realizing the fastening installation between the support piece 23, the lower inner panel 22 of the front pillar and the transition piece 5. The load received by the reinforcing cross beam 4 is transmitted to the lower inner panel 22 of the front pillar through the transition piece 5. Due to the fastening installation between the support piece 23, the lower inner panel 22 of the front pillar and the transition piece 5, the load transmitted to the lower inner panel of the front pillar 2 is transmitted to the outer panel 21 of the front pillar through the support piece 23. The load transmitted to the lower inner panel of the front pillar 2 is better borne by the support piece 23 and the outer panel 21 of the front pillar, thereby improving the strength and rigidity of the vehicle body assembly, and correspondingly improving the collision performance of the vehicle body assembly.

[0075] In one embodiment, the transition piece 5 is initially positioned by the positioning column 42, and then the connecting portion of the first fastener 6 is passed through the transition piece 5 and the front column 2 to connect with the support member 23 to further position the transition piece 5 based on the initial positioning.

[0076] Exemplarily, the first fastener 6 is a bolt, the connecting portion is a threaded rod of the bolt, and the stopper is a bolt head of the bolt, for example, a hexagonal bolt head.

[0077] In one embodiment, please refer to Figure 2 to Figure 8 The connecting portion passes through the front pillar adapter 52 and the front pillar lower inner plate 22 , and the front pillar adapter 52 and the front pillar lower inner plate 22 are clamped between the stopper and the support member 23 .

[0078] In one embodiment, please refer to Figure 6 to Figure 8 The support member 23 includes a support shell 231 and a first nut 232. The support shell 231 is welded to the front pillar outer plate 21, and the front pillar lower inner plate 22 and the transition member 5 are clamped between the support shell 231 and the stopper. The first nut 232 is installed on the side of the support shell 231 away from the front pillar lower inner plate 22, and the connecting portion is penetrated through the support shell 231 to be threadedly connected with the first nut 232. With such a structural form, the support shell 231 is a shell-like structure, and the shell-like structure of the support shell 231 is conducive to reducing the weight of the support member 23. The first screw is installed on the side of the support shell 231 away from the front pillar lower inner plate 22, and the connecting portion of the first fastener 6 can pass through the transition member 5, the front pillar lower inner plate 22 and the support shell 231 and be screwed into the first nut 232 to be threadedly connected with the first nut 232, thereby tightening the transition member 5 and the front pillar lower inner plate 22 on the support shell 231. By setting the first nut 232 , the first fastener 6 can be operated outside the space enclosed by the front pillar outer panel 21 and the front pillar lower inner panel 22 to achieve fastening connection between the transition piece 5 , the front pillar lower inner panel 22 and the support piece 23 .

[0079] Exemplarily, the supporting shell 231 and the first nut 232 are welded.

[0080] In one embodiment, the first nut 232 can be replaced by a clip, and the connecting portion of the first fastener 6 passes through the transition piece 5, the lower inner plate 22 of the front pillar and the support shell 231 and is inserted into the clip to be clipped with the clip.

[0081] In one embodiment, please refer to Figure 6 to Figure 8The support shell 231 includes a second wing plate 2311, a second connecting plate 2312, and a second mounting plate 2313. The second wing plate 2311 is welded to the front pillar outer plate 21. The second connecting plate 2312 is connected to the side of the second wing plate 2311 away from the front pillar outer plate 21. The second mounting plate 2313 is connected to the side of the second connecting plate 2312 away from the second wing plate 2311. The second connecting plate 2312 and the second wing plate 2311 are provided at opposite ends of the second mounting plate 2313 in the up-down direction. The second connecting plates 2312 at both ends are located between the second wing plates 2311 at both ends. The first nut 232 is installed on the side of the second mounting plate 2313 away from the lower inner plate 22 of the front pillar, and the connecting portion is penetrated through the second mounting plate 2313. With such a structural form, the support shell 231 is roughly constructed into an "J"-shaped structure through the second wing plate 2311, the second connecting plate 2312 and the second mounting plate 2313. The cavity portion of the "J"-shaped structure of the support shell 231 faces the front pillar outer plate 21, so that the side of the second mounting plate 2313 away from the lower inner plate 22 of the front pillar has sufficient space to accommodate the first nut 232. The "J"-shaped structure of the support shell 231 makes the support shell 231 have better strength and rigidity, which is beneficial for the load transmitted to the lower inner plate 22 of the front pillar to be transmitted to the outer shell of the front pillar 2 through the support shell 231, thereby improving the strength and rigidity of the body assembly.

[0082] Exemplarily, the first nut 232 is welded to the second mounting plate 2313 .

[0083] The embodiment of the present application is not limited to the welding of the support member 23 and the outer shell of the front pillar 2. In one embodiment, the support member 23 and the outer shell of the front pillar 2 are connected by bolts.

[0084] Exemplarily, when the support member 23 and the outer shell of the front pillar 2 are connected by bolts, the support member 23 and the lower inner plate 22 of the front pillar can be welded.

[0085] In one embodiment, please refer to Figure 3 and Fig. 9 The reinforcing cross beam 4 also includes a third nut 44 and a third fastener 45. The third nut 44 is installed on the side of the beam body 41 facing the front wall plate 3. The third fastener 45 passes through the transition piece 5 and the beam body 41 and is threadedly connected to the third nut 44. The transition piece 5 is partially clamped between the third fastener 45 and the beam body 41.

[0086] Exemplarily, the third fastener 45 is a bolt.

[0087] The above embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Any equivalent substitution or change made by a person skilled in the art based on the present invention is within the protection scope of the present invention.
