Detailed Implementation
[0046] The embodiments of the present invention will be described below 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 content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed 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 and 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 representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.
[0048] For related technologies, please refer to Figure 1The main body, front pillar 2, and front wall panel 3 enclose a passenger compartment 31 and an engine compartment 32 located at the front of the passenger compartment 31. The front wall panel 3 and the lower inner panel 22 of the front pillar are connected, but the reinforcing crossbeam 4 installed on the front wall panel 3 is arranged at intervals with the front pillar 2. The reinforcing crossbeam 4 and the front pillar 2 are disconnected and not connected together. The force transmission path between the reinforcing crossbeam 4 and the front pillar 2 is broken. The load on the reinforcing crossbeam 4 needs to be indirectly transmitted to the lower inner panel 22 of the front pillar through the front wall panel 3. The reinforcing crossbeam 4 cannot directly transmit the load to the front pillar 2 and cannot play an effective reinforcing role. As a result, the strength and rigidity of the body assembly are relatively low. Therefore, the collision performance of the body assembly is poor.
[0049] In view of this, embodiments of this application provide a vehicle, including a body assembly and a vehicle body, wherein the vehicle body is mounted on the body assembly.
[0050] For example, the vehicle body may include structures such as an engine, wheels, and a drive axle. The engine drives the wheels to rotate, or the engine drives the wheels to rotate via the drive axle, thereby moving the entire vehicle.
[0051] The vehicle body assembly in this embodiment includes a body body and a front pillar 2. The front pillar 2 includes an outer front pillar panel 21, a lower inner front pillar panel 22, and a support member 23. The outer front pillar panel 21 is connected to the body body, the lower inner front pillar panel 22 is located inside the outer front pillar panel 21, and the support member 23 is located within the space enclosed between the outer front pillar panel 21 and the lower inner front pillar panel 22. The support member 23 is connected to both the outer front pillar panel 21 and the lower inner front pillar panel 22. This structural configuration utilizes the front pillar 2 to support the body body, giving the vehicle body assembly a certain strength.
[0052] For example, the lower inner panel 22 of the front pillar can be connected to the main body of the vehicle.
[0053] In one embodiment, please refer to Figure 2 and Figure 3 The body assembly also includes a front wall panel 3, which, together with the body body and the front pillar 2, forms a passenger compartment 31 and an engine compartment 32 located at the front of the passenger compartment 31. In this way, the front wall panel 3 is used to divide the space inside the body body into a passenger compartment 31 for seating and an engine compartment 32 for mounting the engine.
[0054] It should be explained that the front pillar 2 is roughly located between the engine compartment 32 and the driver's compartment 31. In the automotive industry, the front pillar 2 is usually referred to as the A-pillar.
[0055] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 9The body assembly also includes a reinforcing crossbeam 4, which is installed on the side of the front wall panel 3 facing the passenger compartment 31. In this way, the reinforcing crossbeam 4 is used to strengthen the front wall panel 3, which can improve the strength of the front wall panel 3 to a certain extent and increase its resistance to deformation.
[0056] In one embodiment, please refer to Figures 2-5 The vehicle assembly also includes a transition piece 5. The transition piece 5 is installed on the reinforcing crossbeam 4 and the lower inner panel 22 of the front pillar, respectively. Thus, since the transition piece 5 is installed on the reinforcing crossbeam 4 and the lower inner panel 22 of the front pillar, a force transmission channel is established between the reinforcing crossbeam 4 and the lower inner panel 22 of the front pillar through the transition piece 5. The lower inner panel 22 of the front pillar is supported by the support piece 23. The load borne by the reinforcing crossbeam 4 can be transferred to the lower inner panel 22 of the front pillar through the transition piece 5. The load transferred to the lower inner panel 22 of the front pillar can be transferred 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 usually greater than that of the lower inner panel 22 of the front pillar, and the strength of the outer panel 21 of the front pillar is usually greater than that of the lower inner panel 22 of the front pillar. The outer panel 21 of the front pillar is not easily deformed and can better bear the load. Therefore, a force transmission channel is established between the reinforcing beam 4 and the front pillar outer plate 21. The load of the reinforcing beam 4 can be transferred to the front pillar outer plate 21 through the transition piece 5, so that the body body can bear the load better, improving the strength and rigidity of the body assembly, thereby improving the collision performance of the body assembly.
[0057] In one embodiment, please refer to Figures 2-5 The transition component 5 includes a crossbeam adapter 51 and a front pillar adapter 52. The crossbeam adapter 51 is installed on the reinforcing crossbeam 4. The front pillar adapter 52 is connected to the crossbeam adapter 51 and contacts the lower inner plate 22 of the front pillar. With this structure, through the contact between the front pillar adapter 52 and the lower inner plate 22 of the front pillar, the load of the front pillar adapter 52, which is held by the stop and the support 23, can be distributed as much as possible by the lower inner plate 22 of the front pillar and transferred to the support 23, so that the lower inner plate 22 of the front pillar can better transfer the load of the front pillar adapter 52.
[0058] In one embodiment, please refer to Figures 2-4 The front pillar adapter 52 is flat. In this way, the flat front pillar adapter 52 can fit well with the lower inner panel 22 of the front pillar, which is conducive to the better transfer of load to the lower inner panel 22 of the front pillar through the front pillar adapter 52, and the flat front pillar adapter 52 helps to appropriately reduce weight.
[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 requirement that the front pillar adapter 52 contacts the surface of the lower inner plate 22 of the front pillar.
[0060] It can be understood that the front pillar adapter 52 and the lower inner panel 22 of the front pillar are not limited to surface contact. The front pillar adapter 52 can arch at the position corresponding to the fastener to be spaced apart from the lower inner panel 22 of the front pillar. It is only necessary to install the transition member 5 on the reinforcement cross beam 4 and the lower inner panel 22 of the front pillar so that the load of the reinforcement cross beam 4 can be transmitted to the outer panel 21 of the front pillar.
[0061] In one embodiment, please refer to Figure 4 and Figure 5 , the cross 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 facing away from the front wall panel 3. The first mounting plate 513 is respectively connected to the first connecting plate 512 and the reinforcement cross beam 4. The first mounting plate 513 is located on the side of the first connecting plate 512 facing away from the first wing plate 511. The reinforcement cross beam 4 is located on the side of the first mounting plate 513 facing the front wall panel 3. The arrangement direction of the first mounting plate 513 and the reinforcement cross beam 4 is the first direction. The direction that intersects both the first direction and the length direction of the reinforcement cross beam 4 is the second direction. Both ends of the first mounting plate 513 in the second direction are provided with the first connecting plate 512 and the first wing plate 511. The two end first connecting plates 512 are located between the two end first wing plates 511. In such a structural form, the cross beam adapter 51 generally forms a structure in the shape of a capital "J" through the first wing plate 511, the first connecting plate 512 and the first mounting plate 513. The cavity is enclosed between the structure in the shape of a capital "J" formed by the cross beam adapter 51 and the front wall panel 3. The cross beam adapter 51 can increase the strength of the cross beam adapter 51 through the structure in the shape of a capital "J", which is beneficial to the cross beam adapter 51 for transmitting the load. The cavity structure enclosed between the cross beam adapter 51 and the front wall panel 3 is both beneficial to partially accommodate the reinforcement cross beam 4 so that the cross beam adapter 51 can be installed on the reinforcement cross beam 4 and beneficial to reducing the weight of the cross beam adapter 51.
[0062] Exemplarily, please refer to Figure 2 , the first direction is the direction indicated by the arrow R1 in the figure.
[0063] Exemplarily, the first direction is generally along the length direction of the vehicle body main body.
[0064] Exemplarily, please refer to Figure 2 , the second direction is the direction indicated by the arrow R2 in the figure.
[0065] Exemplarily, the second direction is generally along the height direction of the vehicle body main body.
[0066] It can be understood that the cross-sectional shape of the cross beam adapter 51 is not limited to the structure in the shape of a capital "J", and other shapes are also possible.
[0067] In one embodiment, please refer to Figure 4The transition piece 5 also includes reinforcing ribs 53, which are connected to the front pillar adapter 52 and the first mounting plate 513 respectively. This structural configuration, through the reinforcing ribs 53 connected to the front pillar adapter 52 and the first mounting plate 513 respectively, reduces 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 front column adapters 52 are connected to the crossbeam adapter 51. The two front column adapters 52 are arranged at intervals, and the reinforcing ribs 53 are 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 column adapter 52 on the side opposite to the lower inner plate 22 of the front column, and the reinforcing rib 53 protrudes from the first mounting plate 513 on the side opposite to the front wall plate 3.
[0071] In one embodiment, please refer to Figure 3 , Figure 4 and Figure 9 The transition piece 5 has a positioning hole 54, and the reinforcing beam 4 includes a beam body 41, a positioning post 42, and a second fastener 43. The beam body 41 is connected to the transition piece 5. The positioning post 42 is connected to the side of the beam body 41 away from the front wall panel 3, and the positioning post 42 passes through the positioning hole 54. The second fastener 43 is installed on the positioning post 42 to partially clamp the transition piece 5 between the second fastener 43 and the beam body 41. With this structure, during installation, the transition piece 5 can be initially positioned by fitting it onto the positioning post 42 through the positioning hole 54. The positioning post 42 passes through the positioning hole 54, and the transition piece 5 can be clamped at the corresponding position of the positioning post 42 by the second fastener 43 and the reinforcing beam 4 to achieve installation. The second fastener 43 secures the transition piece 5 to the beam body 41, making the transition piece 5 more firmly installed, which is beneficial for the transition piece 5 to better transfer 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. The second nut is threadedly connected to the positioning post 42.
[0073] It is understandable that the support member 23 is located in the space enclosed between the outer plate 21 of the front pillar and the lower inner plate 22 of the front pillar. Since the space enclosed between the outer plate 21 of the front pillar and the lower inner plate 22 of the front pillar is relatively narrow or even relatively closed, it is difficult for the welding gun or welding rod to be inserted into the space between the outer plate 21 of the front pillar and the lower inner plate 22 of the front pillar to weld the support member 23. Therefore, it is difficult to connect the outer plate 21 of the front pillar and the lower inner plate 22 of the front pillar to the support member 23 by welding. When the support member 23 is welded to the outer plate 21 of the front pillar, the support member 23 needs to be welded to the outer plate 21 of the front pillar before the inner plate 22 of the front pillar is covered by the outer plate 21 of the front pillar. Then the inner plate 22 of the front pillar is covered by the outer plate 21 of the front pillar so that the support member 23 is located in the space between the inner plate 22 of the front pillar and the outer plate 21 of the front pillar. Since the space between the inner plate 22 of the front pillar and the outer plate 21 of the front pillar is narrow or even closed, it is difficult to weld the support member 23. Therefore, when the support member 23 is welded to the outer plate 21 of the front pillar, it is almost impossible to weld the support member 23 to the inner plate 22 of the front pillar.
[0074] In one embodiment, please refer to Figures 2-8 The support member 23 is welded to the outer panel 21 of the front pillar. The body assembly also includes a first fastener 6, which includes a connecting part and a stop part that are interconnected. The connecting part passes through the transition member 5 and the lower inner panel 22 of the front pillar, and is connected to the support member 23. The lower inner panel 22 of the front pillar and the transition member 5 are both sandwiched between the support member 23 and the stop part. With this structural form, the welding of the support member 23 to the outer panel 21 of the front pillar has little impact on the appearance quality of the outer side of the front pillar 21 away from the support member 23. The outer side of the front pillar 21 away from the support member 23 can still basically maintain a good appearance quality. The transition piece 5, the lower inner panel 22 of the front pillar, and the support piece 23 are fastened together using the first fastener 6. The first fastener 6 connects to the support piece 23, clamping the lower inner panel 22 of the front pillar and the transition piece 5 between the support piece 23 and the stop, thus achieving a secure installation between the support piece 23, the lower inner panel 22 of the front pillar, and the transition piece 5. The load on the reinforcing beam 4 is transferred to the lower inner panel 22 of the front pillar through the transition piece 5. Due to the secure installation between the support piece 23, the lower inner panel 22 of the front pillar, and the transition piece 5, the load transferred to the lower inner weight of the front pillar 2 is transferred to the outer panel 21 of the front pillar through the support piece 23. The load transferred to the lower inner weight of the front pillar 2 is well supported by the support piece 23 and the outer panel 21 of the front pillar, thereby improving the strength and rigidity of the body assembly and correspondingly improving the collision performance of the body assembly.
[0075] In one embodiment, the transition piece 5 is initially positioned by the positioning post 42, and then the connecting part of the first fastener 6 passes through the transition piece 5 and the front column 2 to connect with the support piece 23 to further position the transition piece 5 based on the initial positioning.
[0076] For example, the first fastener 6 is a bolt, the connecting part is the shank of the bolt with threads, and the stop part is the bolt head. For example, the stop part is a hexagonal bolt head.
[0077] In one embodiment, please refer to Figures 2-8 The connecting part passes through the front pillar adapter 52 and the lower inner plate 22 of the front pillar, and the front pillar adapter 52 and the lower inner plate 22 of the front pillar are sandwiched between the stop and the support 23.
[0078] In one embodiment, please refer to Figures 6-8 The support member 23 includes a support shell 231 and a first nut 232. The support shell 231 is welded to the outer plate 21 of the front pillar, and the lower inner plate 22 of the front pillar and the transition member 5 are both sandwiched between the support shell 231 and the stop portion. The first nut 232 is installed on the side of the support shell 231 away from the lower inner plate 22 of the front pillar, and the connecting part passes through the support shell 231 to be threadedly connected to the first nut 232. With this structural form, the support shell 231 has a shell-like structure, which helps to reduce the weight of the support member 23. The first thread is installed on the side of the support shell 231 away from the lower inner plate 22 of the front pillar, and the connecting part of the first fastener 6 can pass through the transition member 5, the lower inner plate 22 of the front pillar, and the support shell 231 to be screwed into the first nut 232 to be threadedly connected to the first nut 232, thereby tightening the transition member 5 and the lower inner plate 22 of the front pillar onto 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 plate 21 and the front pillar lower inner plate 22 to achieve a fastening connection between the transition piece 5, the front pillar lower inner plate 22 and the support piece 23.
[0079] For example, the support shell 231 is welded to the first nut 232.
[0080] In one embodiment, a snap-fit connector can be used instead of the first nut 232. The connecting portion of the first fastener 6 passes through the transition piece 5, the lower inner plate 22 of the front column, and the support shell 231 and is inserted into the snap-fit connector to snap into it.
[0081] In one embodiment, please refer to Figures 6-8The 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 outer plate 21 of the front pillar. The second connecting plate 2312 is connected to the side of the second wing plate 2311 away from the outer plate 21 of the front pillar. 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 mounting plate 2313 has a second connecting plate 2312 and a second wing plate 2311 at both ends along the vertical direction. The second connecting plates 2312 at both ends are located between the second wing plates 2311 at both ends. A 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 part passes through the second mounting plate 2313. With this structural form, the support shell 231 is roughly constructed in a Z-shape through the second wing plate 2311, the second connecting plate 2312, and the second mounting plate 2313. The cavity part of the Z-shaped structure of the support shell 231 faces the outer plate 21 of the front pillar, so that the side of the second mounting plate 2313 away from the lower inner plate 22 of the front pillar has enough space to accommodate the first nut 232. The Z-shaped structure of the support shell 231 gives the support shell 231 good strength and rigidity, which is conducive to the transfer of the load to the lower inner plate 22 of the front pillar through the support shell 231 to the outer shell of the front pillar 2, thereby improving the strength and rigidity of the vehicle body assembly.
[0082] For example, the first nut 232 is welded to the second mounting plate 2313.
[0083] The embodiments of this application are not limited to the support member 23 being welded to the outer shell of the front column 2. In one embodiment, the support member 23 and the outer shell of the front column 2 are bolted together.
[0084] For example, when the support member 23 and the front column 2 housing are bolted together, the support member 23 and the lower inner plate 22 of the front column can be welded together.
[0085] In one embodiment, please refer to Figure 3 and Figure 9 The reinforcing 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 41 facing the front wall panel 3. The third fastener 45 passes through the transition piece 5 and the beam 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 41.
[0086] For example, the third fastener 45 is a bolt.
[0087] The above embodiments are merely preferred embodiments provided to fully illustrate the present invention, and the scope of protection of the present invention is not limited thereto.
