Description

Technical Field

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

[0002] The vehicle body is usually formed by stamping and welding sheet metal materials. To meet the requirements of the vehicle body structure strength, some vehicle body structures, such as A-pillars, B-pillars, C-pillars, sill beams, etc., are composed of an inner panel, an outer panel, and a reinforcing plate. The inner panel and the outer panel are respectively welded to opposite sides of the reinforcing plate, and a cavity is formed between the inner panel and the outer panel. The reinforcing plate divides the cavity into two chambers. During the driving process of the vehicle, high-speed air flow turbulence will be generated in the cavity. The turbulent air flow resonates with the inner panel, the outer panel, and the reinforcing plate, generating relatively large noise. Therefore, it is necessary to fill and seal the cavity.

[0003] In the prior art, filling members are respectively arranged in the two chambers of the vehicle body structure. The filling members are in interference fit with the inner walls of the chambers, thereby reducing the vibration frequency of the inner panel, the outer panel, and the reinforcing plate, alleviating resonance, and thus reducing noise.

[0004] However, the above method requires a filling member to be respectively arranged in each chamber, and the assembly steps are relatively complex, resulting in a low assembly efficiency of the vehicle body structure. Summary of the Invention

[0005] One of the purposes of the present invention is to provide a vehicle body structure to solve the problem in the prior art that a filling member needs to be respectively arranged in each cavity of the vehicle body structure for noise reduction, and the assembly steps are relatively complex, resulting in a low assembly efficiency of the vehicle body structure; the second purpose is to provide a vehicle.

[0006] To achieve the above purposes, the technical solution adopted by the present invention is as follows:

[0007] A vehicle body structure for a vehicle, comprising: an outer panel; an inner panel connected to the outer panel and jointly defining a cavity; a reinforcing plate disposed in the cavity, the reinforcing plate dividing the cavity into a first chamber and a second chamber, the first chamber being located on the side of the reinforcing plate facing the outer panel, the second chamber being located on the side of the reinforcing plate facing the inner panel, and a communication hole communicating the first chamber and the second chamber being formed on the reinforcing plate; a filling member disposed at the communication hole, the filling member filling at least part of the structures of the first chamber and the second chamber respectively.

[0008] According to the above technical means, the filling member passes through the communication hole and fills at least part of the structures of the first chamber and the second chamber at the same time. The filling member forms an interference fit with at least part of the structures of the reinforcing plate, the inner plate and the outer plate. Thus, the filling member can play a certain vibration damping effect, reduce the vibration frequency of the reinforcing plate, the inner plate and the outer plate, thereby reducing resonance. In addition, the filling member can divide the cavity into smaller chambers, which can reduce the amplification effect of the cavity on noise, thereby reducing the noise inside the vehicle and being beneficial to improving the use experience of the vehicle. Therefore, for the body structure provided in this application, by opening a communication hole in the reinforcing plate, the filling member penetrates through the reinforcing plate via the communication hole and fills the first chamber and the second chamber at the same time. Compared with the prior art where filling members need to be separately arranged in the first chamber and the second chamber, the body structure of this application only needs to install the filling member once during assembly, which is beneficial to simplifying the assembly steps of the body structure and improving the assembly efficiency of the body structure.

[0009] Further, the filling member is detachably connected to at least one of the outer plate and the inner plate.

[0010] According to the above technical means, when the filling member needs to be replaced due to an installation error, it only needs to be removed from the inner plate or the outer plate, without damaging the inner plate or the outer plate, which is beneficial to reducing the skill requirements for the body structure assembly personnel.

[0011] Further, one of the filling member and the outer / inner plate is provided with a buckle, and the other is provided with a card hole. The buckle passes through the card hole and is in snap-fit connection with the card hole.

[0012] According to the above technical means, the connection between the filling member and the outer plate is realized through the snap-fit connection between the buckle and the card hole, with a simple structure and convenient operation, which is beneficial to simplifying the assembly process of the filling member and further improving the assembly efficiency of the body structure.

[0013] Further, the filling member includes: a support body, including a first side surface and a second side surface opposite to each other along its own thickness direction; an expansion body, provided on at least one of the first side surface and the second side surface, and the expansion body is used to fill the cavity.

[0014] According to the above technical means, if the expansion body directly expands, it may expand to interfere with other structures on the body structure, affecting the next processing of the body structure. Therefore, a support body is provided, and the expansion member is arranged on the first side surface or the second side surface of the support body, so as to limit the expansion of the expansion body to the other side of the support body, playing a guiding and limiting role in the expansion of the expansion body, which is beneficial to ensuring the structural integrity of other parts of the body structure.

[0015] Further, the expansion body is provided on the first side surface of the support body, and the area of the projection of the expansion body on the first side surface is smaller than the area of the first side surface.

[0016] According to the above technical means, the support member is used to limit the expansion direction of the expansion body. The area of the support member needs to be slightly larger than that of the expansion body to prevent the expansion body from bypassing the support body and expanding towards the second side surface of the support body after expansion, which is beneficial to ensuring the limiting and guiding effects of the support body.

[0017] Further, the communication hole includes two first side edges opposite to each other in the first direction and two second side edges opposite to each other in the second direction. The length of the first side edge is greater than the length of the second side edge. The support body is spaced apart from at least one of the first side edge and the second side edge; the first direction intersects the second direction.

[0018] According to the above technical means, after the filling member is installed and heated, the volume of the expansion body will expand and become larger. Therefore, a certain gap needs to be reserved between the support body and at least one of the first side edge and the second side edge. In this way, there is also a certain gap between the expansion body on the support body and the first side edge and the second side edge, so as to reserve space for the expansion of the expansion body and avoid damage and deformation of the reinforcement plate caused by the excessive extrusion of the communication hole when the expansion body expands.

[0019] Further, the support body is spaced apart from the first side edge and the second side edge respectively; wherein, the distance between the support body and the first side edge is greater than the distance between the support body and the second side edge.

[0020] According to the above technical means, the purpose of reserving the distance between the support body and the second side edge is to reserve expansion space for the expansion body. After the expansion body expands, the expansion body abuts against the second side edge to achieve sealing; the purpose of reserving a larger distance between the support body and the first side edge is to reserve a certain installation space for the filling member. When assembling the body structure, the filling member needs to be first snapped onto the inner panel, and then the reinforcement plate is welded to the inner panel. At this time, the assembler needs to check the workpiece to ensure whether the filling member has been assembled. If it is found that there is a missing installation, the filling member can be snapped onto the inner panel through the communication hole without removing the reinforcement plate to complete the installation of the filling member. Finally, the outer panel is welded to the reinforcement plate.

[0021] Further, the distance between the support body and the first side edge is 12 mm - 15 mm; and / or, the distance between the support body and the second side edge is 2 mm - 4 mm.

[0022] According to the above technical means, if the distance between the support body and the first side is too large, it may be difficult for the structural strength of the reinforcement plate to meet the requirements of the vehicle body structure. If the distance is too small, there may not be enough space for the fingers of the assembler to pass through the communication hole, making it difficult to accurately snap the filler onto the inner panel. If the distance between the support body and the second side is too large, it may result in the expansion body still being unable to abut against the second side after expansion, resulting in poor sealing effect. If the distance is too small, it may lead to insufficient expansion space for the expansion body, excessive extrusion of the communication hole, and damage to the reinforcement plate.

[0023] Furthermore, the filler is provided with a liquid passage hole penetrating along its thickness direction, and the liquid passage hole is used for the flow of electrophoresis liquid.

[0024] According to the above technical means, a liquid passage hole is opened on the filler so that the electrophoresis liquid can flow smoothly through the liquid passage hole, ensuring sufficient electrophoresis in the cavity and guaranteeing the anti-corrosion effect. After the expansion body expands due to heat, the liquid passage hole is blocked due to the expansion of the expansion body, so it will not affect the sealing effect of the filler.

[0025] Furthermore, the outer panel includes a first panel body and first connecting edges provided on opposite sides of the first panel body along the second direction. The inner panel includes a second panel body and second connecting edges provided on opposite sides of the second panel body along the second direction. The outer panel includes a third panel body and third connecting edges provided on opposite sides of the third panel body along the second direction. The first connecting edge, the third connecting edge, and the second connecting edge are arranged and connected in sequence in a stacked manner. At least one of the first panel body and the second panel body is recessed away from the other to form the cavity.

[0026] According to the above technical means, the first connecting edge, the third connecting edge, and the second connecting edge are fixed together in sequence by spot welding, laser welding, etc. to form the vehicle body structure, which can reduce jigs and processes, and is beneficial to further improving the assembly efficiency of the vehicle body structure. The cavity can deform orderly to absorb energy during a vehicle collision, reduce the intrusion amount of the vehicle's occupant compartment, and reserve sufficient living space inside the vehicle, which is beneficial to improving the safety of the vehicle.

[0027] Furthermore, an assembly gap is formed at the connection between the second connecting edge and the third connecting edge. Assembly tentacles are respectively provided on opposite sides of the filler along the second direction, and the assembly tentacles are snapped into the assembly gap.

[0028] According to the above technical means, since the space at the assembly gap is small, it is necessary to set assembly tentacles on the filler that match the shape of the assembly gap and snap the assembly tentacles into the assembly gap to ensure that when the expansion body expands, it can fill all parts of the cavity and avoid omission, resulting in a gap between the expansion body and the inner panel, outer panel, or reinforcement plate after expansion, which affects the sealing effect.

[0029] A vehicle, comprising any one of the above body structures.

[0030] According to the above technical means, by setting the above body structure, the production cost of the body structure can be effectively saved, the assembly efficiency of the body structure can be improved, thereby saving the cost of the vehicle, and at the same time, the noise in the passenger compartment of the vehicle is reduced, which is beneficial to improving the use experience of the vehicle.

[0031] Advantages of the present invention:

[0032] (1) In the present invention, a communication hole is opened on the reinforcing plate, and the filling member passes through the communication hole and fills both the first chamber and the second chamber at the same time. When assembling the body structure, only one installation of the filling member is required, which is beneficial to improving the assembly efficiency of the body structure.

[0033] (2) A relatively large gap is reserved between the side of the communication hole of the present invention and the filling member, so that when the filling member is missed, the assembly personnel can manually install the filling member on the inner plate through the communication hole, which is beneficial to improving the fault tolerance rate of the body structure assembly.

[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 content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments. 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, rather than for limiting the protection scope of the present invention.

[0047] As shown in the background art, in the prior art, it is necessary to respectively arrange fillers in two cavities of the vehicle body structure, and the fillers are in interference fit with the inner walls of the cavities, so as to reduce the vibration frequency of the inner plate, outer plate and reinforcement plate, reduce resonance, and thus reduce noise. However, arranging a filler in each cavity requires assembling the filler at least twice, and the assembly steps are relatively complex, resulting in a low assembly efficiency of the vehicle body structure.

[0048] In view of the above - mentioned technical problems, the embodiments of the present application provide a vehicle body structure and a vehicle. The vehicle body structure includes an outer plate, an inner plate, a reinforcement plate and a filler. The inner plate and the outer plate jointly define a cavity. The reinforcement plate divides the cavity into a first cavity and a second cavity. A communication hole is opened on the reinforcement plate. The filler passes through the communication hole and fills at least part of the structures of the first cavity and the second cavity at the same time. The filler forms an interference fit with at least part of the structures of the reinforcement plate, inner plate and outer plate. Thus, the filler can play a certain vibration - damping effect, reduce the vibration frequency of the reinforcement plate, inner plate and outer plate, thereby reducing resonance. In addition, the filler can divide the cavity into smaller cavities, which can reduce the amplification effect of the cavity on noise, thereby reducing the noise inside the vehicle and being beneficial to improving the use experience of the vehicle. Therefore, for the vehicle body structure provided by the present application, by opening a communication hole on the reinforcement plate and the filler passing through the communication hole to penetrate the reinforcement plate and fill the first cavity and the second cavity at the same time, compared with the prior art where fillers need to be respectively arranged in the first cavity and the second cavity, the vehicle body structure of the present application only needs to install the filler once during assembly, which is beneficial to simplifying the assembly steps of the vehicle body structure and improving the assembly efficiency of the vehicle body structure.

[0049] The following describes in detail the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems with specific embodiments. The following several specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments. The embodiments of the present application will be described below with reference to the drawings:

[0050] It should be noted that the body structure provided in the embodiments of the present application can be applied to various different vehicles.

[0051] See Figure 1 、 Figure 2 and Figure 3 As shown in, the embodiments of the present application provide a body structure 100 for a vehicle, including an outer panel 110, an inner panel 120, a reinforcement panel 130, and a filler 140. Among them, the inner panel 120 is connected to the outer panel 110 and jointly defines a cavity; the reinforcement panel 130 is disposed in the cavity, and the reinforcement panel 130 divides the cavity into a first chamber 1111 and a second chamber 1211. The first chamber 1111 is located on the side of the reinforcement panel 130 facing the outer panel 110, and the second chamber 1211 is located on the side of the reinforcement panel 130 facing the inner panel 120. A communication hole 1311 communicating the first chamber 1111 and the second chamber 1211 is formed on the reinforcement panel 130; the filler 140 is disposed at the communication hole 1311, and the filler 140 fills at least part of the structures of the first chamber 1111 and the second chamber 1211 respectively.

[0052] It can be understood that when the vehicle is running, high-speed airflows will be generated in both the first chamber 1111 and the second chamber 1211. The high-speed airflows rub against the obstacles in the cavity to form eddy currents, and then turbulent airflow noise is generated. At the same time, the frequency of the turbulent airflow is close to the natural frequencies of the reinforcement panel 130, the inner panel 120, and the outer panel 110. Therefore, resonance will occur and resonance noise will be generated. The resonance noise and the turbulent airflow noise are propagated and amplified by the cavity, resulting in a relatively large noise heard by the user in the vehicle and affecting the driving experience of the vehicle. Therefore, it is necessary to provide the filler 140. On the one hand, it blocks the cavity to prevent the formation of eddy currents and at the same time prevents the propagation of noise. On the other hand, it reduces the vibration frequencies of the outer panel 110, the inner panel 120, and the reinforcement panel 130 and reduces resonance.

[0053] In an embodiment of the present application, a communication hole 1311 is formed in the reinforcing plate 130. The filling member 140 passes through the reinforcing plate 130 via the communication hole 1311 and fills part of the structures of the first chamber 1111 and the second chamber 1211, thereby blocking the first chamber 1111 and the second chamber 1211, preventing the formation of eddy currents in the first chamber 1111 and the second chamber 1211, reducing the turbulent air flow noise, and blocking the noise propagation. In addition, the filling member 140 forms an interference fit with at least part of the structures of the inner plate 120, the outer plate 110, and the reinforcing plate 130, thereby reducing the frequencies of the inner plate 120, the outer plate 110, and the reinforcing plate 130. Thus, the noise generated during vehicle driving can be reduced. Among them, there can be multiple filling members 140, and the multiple filling members 140 are arranged at intervals along the extending direction of the vehicle body structure 100, dividing the longer cavity into multiple shorter chambers. The communication holes 1311 on the reinforcing plate 130 correspond to the positions of the filling members 140 one by one. The filling member 140 can be made of different materials such as an expansion rubber block, a rubber block, or a foam. The specific material and quantity of the filling member 140 are not limited in the embodiment of the present application and can be reasonably selected according to the actual needs of the vehicle body structure 100.

[0054] Compared with the prior art in which a filling member 140 needs to be provided in each of the first chamber 1111 and the second chamber 1211, in the vehicle body structure 100 provided by the embodiment of the present application, only one filling member 140 needs to be assembled during assembly to complete the sealing and filling of the first chamber 1111 and the second chamber 1211, which is beneficial to simplifying the assembly steps of the vehicle body structure 100 and improving the assembly efficiency of the vehicle body structure 100.

[0055] Further, since the first chamber 1111 and the second chamber 1211 are separated by the reinforcing plate 130, and the first chamber 1111 of part of the vehicle body structure 100 is relatively narrow, it is easy to have problems such as insufficient operating space or difficulty in fixing when installing the filling member 140, and thus it is difficult to meet the sealing and blocking requirements of the cavity. In the embodiment of the present application, the first chamber 1111 and the second chamber 1211 are communicated through the communication hole 1311, and the size of the filling member 140 can be matched with the total space formed by the first chamber 1111 and the second chamber 1211, that is, the overall size of the cavity. Compared with the prior art in which a filling member 140 needs to be installed separately in the first chamber 1111, the filling member 140 of the vehicle body structure 100 in the embodiment of the present application is more convenient to install, is less restricted by space, and is more likely to achieve the sealing and blocking of the cavity.

[0056] In addition, corresponding connection structures such as buckles 1411 and plug-in members need to be provided when fixing each filling member 140. Compared with the prior art in which a filling member 140 is provided in each of the first chamber 1111 and the second chamber 1211, only one filling member 140 is provided in the embodiment of the present application, which can save the cost of setting the connection structure and is beneficial to saving the production cost of the vehicle body structure 100.

[0057] In some implementable ways, referring to Figure 1 , Figure 2 and Figure 3 as shown, the filling member 140 of the embodiment of the present application is detachably connected to at least one of the outer panel 110 and the inner panel 120.

[0058] It can be understood that the filling member 140 is set to be detachably connected to the inner panel 120 or the outer panel 110. When the filling member 140 needs to be replaced due to an installation error, it is only necessary to remove the filling member 140 from the inner panel 120 or the outer panel 110, without damaging the inner panel 120 or the outer panel 110, which is beneficial to reducing the skill requirements for the assembly personnel of the vehicle body structure 100. At the same time, the same filling member 140 can be applied to different vehicle body structures 100, which is beneficial to reducing the development cost of the filling member 140 mold and improving the assembly efficiency of the vehicle body structure 100.

[0059] In some implementable ways, referring to Figure 1 , Figure 2 and Figure 3 as shown, one of the filling member 140 and the inner panel 120 of the embodiment of the present application is provided with a buckle 1411, and the other is provided with a card hole 1212. The buckle 1411 passes through the card hole 1212 and is in snap-fit with the card hole 1212.

[0060] In specific implementation, the connection between the filling member 140 and the outer panel 110 is realized by the snap-fit of the buckle 1411 and the card hole 1212. The structure is simple and the operation is convenient, which is beneficial to simplifying the assembly process of the filling member 140 and further improving the assembly efficiency of the vehicle body structure 100.

[0061] In some implementable ways, referring to Figure 1 , Figure 2 , Figure 3 and Figure 5 as shown, the filling member 140 of the embodiment of the present application includes a support body 141 and an expansion body 142. Wherein, the support body 141 includes a first side surface and a second side surface opposite to each other along its thickness direction; the expansion body 142 is arranged on at least one of the first side surface and the second side surface, and the expansion body 142 is used to fill the cavity.

[0062] In some embodiments, the expansion body 142 may be an expansion rubber block. After the expansion body 142 is installed on the inner plate 120, the reinforcement plate 130 is welded to the inner plate 120 in sequence, and the outer plate 110 is welded to the other side of the reinforcement plate 130 to complete the assembly of the vehicle body structure 100. After that, the expansion rubber block is heated to expand until it is bonded to the inner plate 120, the outer plate 110 and the reinforcement plate 130, thereby forming a continuous sealing layer to achieve a sealed partition of the cavity. The expansion body 142 expands in volume after heating, and can fill irregular gaps in the cavity to ensure the sealing of the filling piece 140. After solidification, a rigid sealing body is formed, which is conducive to improving the anti-deformation ability of the filling piece 140 and maintaining the integrity of the seal for a long time.

[0063] Furthermore, it may be necessary to set mounting holes, fasteners and other structures on the outer panel 110 or the inner panel 120 for installing or connecting other structures in the vehicle. If the expansion body 142 expands directly, it may expand to interfere with the mounting holes, fasteners and other structures, affecting the next processing of the vehicle body structure 100. Therefore, a support body 141 is set, and the expansion member is set on the first side or the second side of the support body 141, so as to limit the expansion of the expansion body 142 toward the other side of the support body 141, thereby guiding and limiting the expansion of the expansion body 142, which is beneficial to ensuring the structural integrity of other parts of the vehicle body structure 100.

[0064] The support body 141 may be a plastic part, a metal plate, etc. The material of the support body 141 is not limited in the embodiment of the present application, as long as it has sufficient strength to limit the expansion direction of the expansion body 142. The buckle 1411 may be integrally formed with the support member, or may be disposed between the support member and the expansion body 142, which is not limited in the embodiment of the present application.

[0065] In some possible implementations, see Figure 1 , Figure 2 and Figure 5 As shown, the expansion body 142 of the embodiment of the present application is arranged on the first side surface of the support body 141, and the projection area of ​​the expansion body 142 on the first side surface is smaller than the area of ​​the first side surface.

[0066] It can be understood that the support member is used to limit the expansion direction of the expansion body 142. The support member needs to be slightly larger than the area of ​​the expansion body 142 to prevent the expansion body 142 from bypassing the support body 141 and expanding toward the second side of the support body 141 after expansion, which is beneficial to ensure the limiting and guiding effect of the support body 141.

[0067] In some possible implementations, see Figure 1 , Figure 2 , Figure 3 and Figure 5As shown in the figure, the communication hole 1311 of the embodiment of the present application includes two first side edges 1311a opposite to each other in the first direction and two second side edges 1311b opposite to each other in the second direction. The length of the first side edge 1311a is greater than the length of the second side edge 1311b. The support body 141 is spaced apart from at least one of the first side edge 1311a and the second side edge 1311b; the first direction intersects the second direction. Among them, Figure 5 the X direction is the first direction and the Y direction is the second direction.

[0068] In a specific implementation, after the filling member 140 is installed, the volume of the heating expansion body 142 will expand and become larger. Therefore, a certain gap needs to be reserved between the support body 141 and at least one of the first side edge 1311a and the second side edge 1311b. In this way, the expansion body 142 on the support body 141 also has a certain gap with the first side edge 1311a and the second side edge 1311b, so as to reserve space for the expansion of the expansion body 142 and avoid damage and deformation of the reinforcement plate 130 caused by the excessive extrusion of the communication hole 1311 when the expansion body 142 expands.

[0069] In some embodiments, the support body 141 is spaced apart from the first side edge 1311a and the second side edge 1311b respectively; among them, the distance between the support body 141 and the first side edge 1311a is greater than the distance between the support body 141 and the second side edge 1311b.

[0070] Among them, the purpose of the distance reserved between the support body 141 and the second side edge 1311b is to reserve expansion space for the expansion body 142. After the expansion body 142 expands, the expansion body 142 abuts against the second side edge 1311b, thereby achieving sealing. If the distance D2 between the support body 141 and the second side edge 1311b is too large, it may cause the expansion body 142 to still not abut against the second side edge 1311b after expansion, resulting in poor sealing effect. If the distance D2 between the support body 141 and the second side edge 1311b is too small, it may cause insufficient expansion space for the expansion body 142, excessive extrusion of the communication hole 1311, and damage to the reinforcement plate 130. Therefore, the distance D2 between the support body 141 and the second side edge 1311b can be set to 2 mm - 4 mm. For example, the distance D2 between the support body 141 and the second side edge 1311b can be 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm. Of course, the specific value of the distance D2 between the support body 141 and the second side edge 1311b in the embodiment of the present application is not limited, and can be reasonably selected within the above range according to the size and shape of the expansion body 142 and the communication hole 1311.

[0071] Further, a larger spacing is reserved between the support body 141 and the first side 1311a for the purpose of reserving a certain installation space for the filling part 140. When assembling the vehicle body structure 100, it is necessary to first snap the filling part 140 onto the inner panel 120, and then weld the reinforcement plate 130 to the inner panel 120. At this time, the assembler needs to inspect the workpiece to ensure whether the filling part 140 has been assembled. If it is found that there is a missing installation, the filling part 140 can be snapped onto the inner panel 120 through the communication hole 1311, and the filling part 140 can be installed without removing the reinforcement plate 130. Finally, the outer panel 110 is welded to the reinforcement plate 130. If the spacing between the support body 141 and the first side 1311a is too small, there is not enough space for the assembler's finger to pass through the communication hole 1311, and it is difficult to accurately snap the filling part 140 onto the inner panel 120. Therefore, a larger spacing is reserved between the support body 141 and the first side 1311a, and the assembler can directly hold the filling part 140 and install the filling part 140 onto the inner panel 120, which is beneficial to improving the fault tolerance rate of the vehicle body structure 100 during the assembly process.

[0072] Among them, if the spacing D1 between the support body 141 and the first side 1311a is too large, the structural strength of the reinforcement plate 130 may be difficult to meet the requirements of the vehicle body structure 100. If the spacing D1 is too small, there may not be enough space for the assembler's finger to pass through the communication hole 1311, and it is difficult to accurately snap the filling part 140 onto the inner panel 120. Therefore, the spacing D1 between the support body 141 and the first side 1311a can be set to 12 mm - 15 mm. For example, the spacing D1 between the support body 141 and the first side 1311a can be 12 mm, 12.5 mm, 13 mm, 13.5 mm, 14 mm, 14.5 mm, or 15 mm. Of course, the specific value of the spacing D1 between the support body 141 and the first side 1311a in the embodiments of the present application is not limited, and can be reasonably selected within the above range according to the size and shape of the expansion body 142 and the communication hole 1311.

[0073] In some implementable ways, as shown in Figure 1 、 Figure 2 、 Figure 3 and Figure 6 shown, the filling part 140 of the embodiment of the present application is provided with a liquid passing hole 1421 penetrating along its own thickness direction, and the liquid passing hole 1421 is used for the flow of electrophoresis liquid.

[0074] In specific implementation, after the body structure 100 is assembled, the inner wall of the cavity, weld seams and other areas that are difficult to spray need to be attached with an electrophoretic layer through the electrophoretic process, effectively isolating moisture, oxygen and corrosive media, preventing the body structure 100 from rusting, and being beneficial to extending the service life of the body structure 100. After the expandable body 142 expands, the cavity will be completely blocked. In order not to affect the electrophoresis of the body structure 100, it is usually necessary to pour the electrophoretic solution before heating to expand the expandable body 142 to achieve electrophoresis. Therefore, in the embodiment of the present application, a liquid passing hole 1421 is opened on the filler 140, and the width of the liquid passing hole 1421 can be set to be greater than 5 mm, so that the electrophoretic solution can flow smoothly through the liquid passing hole 1421, ensuring sufficient electrophoresis in the cavity and guaranteeing the anti-corrosion effect.

[0075] It should be noted that after the expandable body 142 expands due to heat, the liquid passing hole 1421 is blocked due to the expansion of the expandable body 142, so it will not affect the sealing effect of the filler 140.

[0076] In some implementable ways, referring to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 as shown, the outer panel 110 of the embodiment of the present application includes a first panel main body 111 and first connection edges 112 provided on opposite sides of the first panel main body 111 along the second direction. The inner panel 120 includes a second panel main body 121 and second connection edges 122 provided on opposite sides of the second panel main body 121 along the second direction. The outer panel 110 includes a third panel main body 131 and third connection edges 132 provided on opposite sides of the third panel main body 131 along the second direction. The first connection edges 112, the third connection edges 132 and the second connection edges 122 are arranged in a stacked manner and connected in sequence; at least one of the first panel main body 111 and the second panel main body 121 is recessed away from the other to form a cavity.

[0077] In some embodiments, the first connection edges 112, the third connection edges 132 and the second connection edges 122 are fixed together in sequence by spot welding, laser welding and other methods to form the body structure 100, which can reduce jigs and processes, and is beneficial to further improving the assembly efficiency of the body structure 100. The cavity can deform orderly to absorb energy when the vehicle collides, reduce the intrusion amount of the vehicle's occupant compartment, reserve enough living space inside the vehicle, and is beneficial to improving the safety of the vehicle. At the same time, the cavity can also play a certain sound insulation effect, reduce wind noise and road noise, and improve the use experience of the vehicle.

[0078] It should be noted that the shapes of the support body 141 and the expandable body 142 can be cut according to the shapes of the inner panel 120, the outer panel 110 and the reinforcement panel 130 to ensure that the expandable body 142 can fill all the gaps in the cavity and guarantee the sealing effect of the filler 140.

[0079] In some implementable ways, refer to Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, at the connection between the second connecting edge 122 and the third connecting edge 132 of the embodiment of the present application, an assembly gap 1221 is formed; assembly tentacles 1422 are respectively provided on the opposite sides of the filler 140 along the second direction, and the assembly tentacles 1422 are snapped into the assembly gap 1221.

[0080] In specific implementation, since the space at the assembly gap 1221 is small, it is necessary to set the assembly tentacles 1422 on the filler 140 to match the shape of the assembly gap 1221, so that the assembly tentacles 1422 are snapped into the assembly gap 1221, so as to ensure that when the expandable body 142 expands, it can fill each part of the cavity, avoiding omission, resulting in a gap between the expandable body 142 and the inner plate 120, the outer plate 110 or the reinforcing plate 130 after expansion, and affecting the sealing effect.

[0081] Refer to Figure 1 As shown, the embodiment of the present application also provides a vehicle, including any one of the above body structures 100.

[0082] Among them, the specific structure and working principle of the body structure 100 have been described in detail in the above embodiments, and will not be repeated here.

[0083] In the embodiment of the present application, the body structure 100 can be formed as the A-pillar, B-pillar, C-pillar, D-pillar, rear wheel hub cover, etc. of the vehicle. The embodiment of the present application does not limit this. By setting the above body structure 100, the production cost of the body structure 100 can be effectively saved, the assembly efficiency of the body structure 100 can be improved, and then the cost of the vehicle can be saved. At the same time, the noise in the passenger compartment of the vehicle is reduced, which is beneficial to improving the use experience of the vehicle.

[0084] In summary, the vehicle body structure 100 provided by the embodiments of the present application includes an outer panel 110, an inner panel 120, a reinforcing plate 130, and a filler 140. The filler 140 includes a support body 141 and an expansion body 142. The outer panel 110 and the inner panel 120 are respectively welded to opposite sides of the reinforcing plate 130, and the inner panel 120 and the outer panel 110 jointly enclose a cavity. The reinforcing plate 130 divides the cavity into a first chamber 1111 and a second chamber 1211. A communication hole 1311 is formed in the reinforcing plate 130, and the communication hole 1311 communicates the first chamber 1111 with the second chamber 1211. The filler 140 passes through the reinforcing plate 130 via the communication hole 1311 and is snap-connected to the inner panel 120. The expansion body 142 expands when heated, and its volume becomes larger, thereby filling at least part of the structures of the first chamber 1111 and the second chamber 1211. The support body 141 restricts the expansion direction of the expansion body 142 to prevent the expansion body 142 from interfering with other structures on the vehicle body structure 100. Therefore, the vehicle body structure 100 provided by the embodiments of the present application can fill the first chamber 1111 and the second chamber 1211 simultaneously through one filler 140. The filler 140 only needs to be snap-connected to the inner panel 120 to complete the installation, which is simple and convenient to operate, conducive to saving the installation cost of the filler 140, and improving the assembly efficiency of the vehicle body structure 100.
