Description

Technical Field

[0001] The present application belongs to the technical field of vehicle body waterproofing, and more specifically, relates to a vehicle body structure and a vehicle. Background Art

[0002] In existing vehicle body structures, the interior trim layer and the sheet metal layer located inside the interior trim layer are typically positioned relative to each other using studs and nuts. Specifically, the stud's head is connected to the interior trim layer, while the nut is located inside the sheet metal layer. The nut is tightened onto the stud, and a seal is sandwiched between the stud head and the sheet metal. This seal prevents impurities from the exterior of the vehicle body from entering the interior of the sheet metal layer and, subsequently, the vehicle interior.

[0003] With the aforementioned connection method between the interior trim layer and the sheet metal, the seal occupies the entire space between the stud and the sheet metal, preventing the nut from effectively securing the stud to the sheet metal. This leads to torque decay during quality inspection road tests or durability road tests. When the nut's torque decays, the seal loses its ability to properly clamp between the stud and the sheet metal, failing to provide a good seal. This can lead to reduced sealing and even water leakage into the vehicle interior. Summary of the Invention

[0004] The purpose of the embodiments of the present application is to provide a vehicle body structure and a vehicle to solve the technical problem that the connection method used for the interior layer and the sheet metal layer of the existing vehicle body structure easily leads to loss of sealing.

[0005] To achieve the above objectives, the technical solution adopted in this application is:

[0006] A vehicle body structure is provided, the vehicle body structure including a trim part and a sheet metal part, and a connection assembly;

[0007] The connecting assembly includes a first connecting member, a second connecting member and a sealing ring; the first connecting member has a main body and an abutting portion, and the abutting portion is arranged around the circumference of the main body;

[0008] The sheet metal part is provided with a connection hole that passes through the thickness of the sheet metal part, and the main body is inserted into the connection hole; the decorative part and the second connection part are respectively provided on both sides of the sheet metal part and are respectively connected to the main body;

[0009] The abutting portion is located between the decorative component and the sheet metal component, and includes a first ring portion and a second ring portion arranged in radial order. The first ring portion abuts against the sheet metal component, and the sealing ring is sandwiched between the second ring portion and the sheet metal component.

[0010] In some embodiments, the first ring portion and the second ring portion are sequentially arranged along the radially outward direction.

[0011] In some embodiments, along the direction from the trim to the sheet metal component, the first ring portion is protruded relative to the second ring portion, a gap is formed between the second ring portion and the sheet metal component, and the sealing ring is accommodated in the gap.

[0012] In some embodiments, the abutting portion includes two first ring portions and one second ring portion, and one second ring portion is disposed between the two first ring portions.

[0013] In some embodiments, the abutting portion includes two second ring portions and one first ring portion, and one first ring portion is provided between the two second ring portions;

[0014] The vehicle body structure includes two sealing rings, and the two sealing rings and the two second ring portions are arranged in a one-to-one manner.

[0015] In some embodiments, the first connecting member is a threaded member, and the second connecting member is a threaded member;

[0016] The first connecting member and the second connecting member are screwed together, and the first ring portion and the second connecting member are respectively in contact with two sides of the sheet metal component.

[0017] In some embodiments, the first connecting member is a stud structure, and the stud head of the first connecting member is clamped to the decorative member;

[0018] The second connecting member is a nut structure, and the second connecting member is threadedly connected to the threaded portion of the first connecting member.

[0019] In some embodiments, the trim, the sheet metal component, and the second connecting component are sequentially arranged along a direction from the outer side to the inner side of the vehicle body structure.

[0020] In some embodiments, the vehicle body structure includes a plurality of the connection assemblies, and the trim and the sheet metal part are connected via the plurality of the connection assemblies.

[0021] The beneficial effects of the vehicle body structure provided by this application are:

[0022] Compared with the prior art, the vehicle body structure provided by the present application comprises a connecting assembly including a first connecting member, a second connecting member, and a sealing ring. The first connecting member comprises a main body portion and an abutting portion, the abutting portion being arranged circumferentially around the main body portion. Furthermore, the abutting portion is located between the trim and the sheet metal component, and comprises a first ring portion and a second ring portion arranged in radial order. The first ring portion abuts against the sheet metal component, and the sealing ring component is clamped between the second ring portion and the sheet metal component. Thus, the first ring portion abuts against the sheet metal component to provide rigid contact between the first connecting member and the sheet metal component, and the second ring portion and the corresponding sheet metal component provide a clamping position for the sealing ring component.

[0023] The sheet metal component is provided with a connection hole extending through the thickness of the sheet metal component. The main body is inserted into the connection hole. The decorative component and the second connecting component are respectively disposed on either side of the sheet metal component and connected to the main body. The rigid connection between the second connecting component and the first connecting component forces the second connecting component to be fastened to the sheet metal component through the aforementioned rigid contact. Thus, after the relative positions of the first connecting component and the sheet metal component are fixed, due to the rigid contact, the external force generated by the rigid contact must overcome the abutment and friction forces generated by the rigid contact in order to loosen the position of the first connecting component relative to the sheet metal component. For example, if the first and second connecting components are screwed together, the rigid contact can prevent the torque between the two components from being attenuated during testing. Therefore, the rigid contact ensures the stability of the relative positions of the first connecting component and the sheet metal component after they are fixed. The rigid contact further ensures the reliability of the sealing ring configuration, ensuring that the sealing ring is continuously and securely clamped between the second ring portion and the sheet metal component, thereby ensuring a tight seal between the decorative component and the sheet metal component.

[0024] Another object of the present application is to provide a vehicle, comprising a vehicle body structure as described in any one of the above items.

[0025] The vehicle provided in the present application adopts the body structure provided in the present application. By designing the first connecting member in the body structure so that the first ring portion thereof abuts against the sheet metal part, rigid contact between the first connecting member and the sheet metal part can be provided. Through this rigid contact, the stability of the relative position of the first connecting member and the sheet metal part after being fixed is ensured, thereby ensuring the stability of the relative position of the decorative part and the sheet metal part, and improving the stability, durability and safety of the body structure during use.

[0026] In addition, the vehicle provided by the present application enables the sealing ring in its body structure to be clamped between the second ring portion and the corresponding sheet metal part. The above-mentioned rigid contact further ensures the configuration reliability of the sealing ring, and can ensure that the sealing ring is continuously and firmly clamped between the second ring portion and the sheet metal part, thereby ensuring the sealing between the decorative part and the sheet metal part, preventing impurities on the outside of the decorative part from entering the interior of the vehicle, such as preventing water leakage, thereby improving the waterproofness and reliability of the vehicle.

[0043] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0044] The vehicle body structure and vehicle provided in the embodiments of the present application are now described.

[0045] See also Figures 1 to 4 As shown, the vehicle body structure provided in the embodiment of the present application includes a trim 100, a sheet metal component 200, and a connection assembly 300. The connection assembly 300 includes a first connection member 301, a second connection member 302, and a sealing ring member 303. The first connection member 301 has a main body 3011 and an abutment portion 3012. The abutment portion 3012 is arranged around the circumference of the main body 3011.

[0046] The sheet metal component 200 is provided with a connection hole 201 extending through the thickness of the sheet metal component 200, and a main body 3011 is inserted into the connection hole 201. The decorative component 100 and the second connecting component 302 are respectively provided on either side of the sheet metal component 200 and connected to the main body 3011. An abutment portion 3012 is located between the decorative component 100 and the sheet metal component 200 and comprises a first ring portion 3012a and a second ring portion 3012b arranged in radial order. The first ring portion 3012a abuts the sheet metal component 200, and a sealing ring 303 is sandwiched between the second ring portion 3012b and the sheet metal component 200.

[0047] The main body 3011 and the connecting hole 201 are coaxially arranged, and the main body 3011 extends a certain length in the axial direction. The portion of the main body 3011 located on the side of the second connector 302 can extend longer than the portion of the main body 3011 located on the side of the decorative component 100. This maximizes the connection area between the second connector 302 and the first connector 301. For example, when the two are connected by a thread, the extended length of the thread can be maximized, thereby improving the connection strength between the first connector 301 and the second connector 302 and enhancing the abutment stability between the second connector 302 and the sheet metal component 200.

[0048] Among them, the first ring portion 3012a belongs to a part of the annular portion extending circumferentially on the abutting portion 3012, and the second ring portion 3012b belongs to another part of the annular portion extending circumferentially on the abutting portion 3012. The two are staggered in the radial direction. This embodiment does not impose any specific restrictions on the specific order of the first ring portion 3012a and the second ring portion 3012b in the radial direction.

[0049] In the vehicle body structure provided by the embodiment of the present application, the first ring portion 3012a abuts against the sheet metal component 200, and the sealing ring 303 is sandwiched between the second ring portion 3012b and the sheet metal component 200. Thus, the first ring portion 3012a abuts against the sheet metal component 200 to provide rigid contact between the first connecting member 301 and the sheet metal component 200, while the second ring portion 3012b and the corresponding sheet metal component 200 provide a sandwiching position for the sealing ring 303.

[0050] The rigid connection between the second connector 302 and the first connector 301 forces the second connector 302 to be secured to the sheet metal 200 through the aforementioned rigid contact. Thus, after the relative positions of the first connector 301 and the sheet metal 200 are fixed, due to the rigid contact, the external force must overcome the abutment and friction generated by the rigid contact in order to loosen the position of the first connector 301 relative to the sheet metal 200. For example, if the first connector 301 and the second connector 302 are threaded together, the rigid contact can prevent the torque between them from being attenuated during testing. Therefore, the rigid contact ensures the stability of the relative positions of the first connector 301 and the sheet metal 200 after they are fixed. The rigid contact further ensures the reliability of the configuration of the sealing ring 303, ensuring that the sealing ring 303 is continuously and securely clamped between the second ring portion 3012b and the sheet metal 200, thereby ensuring the seal between the decorative component 100 and the sheet metal 200.

[0051] In which, the above-mentioned body structure is applied to a vehicle, the trim 100 can be used as an interior layer inside the vehicle's exterior sheet metal layer, and the sheet metal 200 can be used as an internal sheet metal layer inside the vehicle's interior layer. By setting the above-mentioned connecting component 300, the sealing between the vehicle's interior layer and the internal sheet metal layer can be ensured, and impurities including but not limited to water can be prevented from entering the vehicle from outside the vehicle.

[0052] In some embodiments, the first ring portion 3012a and the second ring portion 3012b are sequentially arranged along the radially outward direction.

[0053] That is, the aforementioned rigid contact is located on the inside, and the sealing ring 303 is located on the outside of the rigid contact. In one aspect, the second ring portion 3012b and the sheet metal member 200 are clamped together to limit the axial position of the sealing ring 303, while the first ring portion 3012a limits the radial position of the sealing ring 303, thereby stabilizing the position of the sealing ring 303 in both the axial and radial directions. In another aspect, the sealing effect can be achieved both by the sealing ring 303 and the rigid contact, and the rigid contact can strengthen and extend the sealing effect of the sealing ring 303.

[0054] Of course, in other embodiments, the first ring portion 3012a and the second ring portion 3012b are sequentially arranged in the radially inward direction. In other words, the rigid contact is located on the outside, and the sealing ring 303 is located on the inside of the rigid contact, and the inner ring side of the sealing ring 303 can contact the main body 3011.

[0055] In one aspect, the second ring portion 3012b and the sheet metal member 200 restrict the axial position of the sealing ring 303, while the first ring portion 3012a and the main body 3011 restrict the radial position of the sealing ring 303, thereby stabilizing the position of the sealing ring 303 in both the axial and radial directions. In another aspect, the sealing function can be achieved both by the sealing ring 303 and by rigid contact, and the rigid contact can strengthen and prolong the sealing function of the sealing ring 303.

[0056] In some embodiments, along the direction of the decorative component 100 pointing to the sheet metal component 200, the first ring portion 3012a is protruded relative to the second ring portion 3012b, a gap is formed between the second ring portion 3012b and the sheet metal component 200, and the sealing ring 303 is accommodated in the gap.

[0057] The sealing ring 303 can be interferingly positioned between the second ring portion 3012b and the sheet metal member 200. The first ring portion 3012a is raised relative to the second ring portion 3012b, ensuring that the first ring portion 3012a is in full rigid contact with the sheet metal member 200, preventing the sealing ring 303 from adversely affecting this rigid contact. Furthermore, the sealing ring 303 can be positioned with space, further stabilizing its position.

[0058] In some embodiments, the abutting portion 3012 includes two first ring portions 3012a and one second ring portion 3012b, with the second ring portion 3012b disposed between the two first ring portions 3012a. Alternatively, in some embodiments, the abutting portion 3012 includes two second ring portions 3012b and one first ring portion 3012a, with the first ring portion 3012a disposed between the two second ring portions 3012b, and the vehicle body structure includes two sealing ring members 303, with the two sealing ring members 303 and the two second ring portions 3012b disposed in a one-to-one relationship.

[0059] In other embodiments, the abutment portion 3012 includes a plurality of second ring portions 3012b and a plurality of first ring portions 3012a, the plurality of first ring portions 3012a and the plurality of second ring portions 3012b are alternately arranged radially, and the vehicle body structure includes a plurality of sealing ring members 303, the plurality of sealing ring members 303 and the plurality of second ring portions 3012b are arranged one to one.

[0060] By changing the number of first ring portions 3012a and the number of second ring portions 3012b, the number of rigid contacts in the radial direction and the number of sealing rings 303 can be increased, so that the rigid contacts are extended larger in the radial direction and spaced in sequence. The sealing rings 303 are arranged in the intervals, which can further enhance the effect of the rigid contacts and further enhance the sealing performance.

[0061] In some embodiments, the first connector 301 is a screw connector, and the second connector 302 is a screw connector. The first connector 301 and the second connector 302 are screwed together, and the first ring portion 3012a and the second connector 302 are respectively in contact with two sides of the sheet metal component 200.

[0062] The first connecting member 301 and the second connecting member 302 are screwed together, and there is torque between the first connecting member 301 and the second connecting member 302. By making the first ring portion 3012a and the second connecting member 302 respectively abut against the two sides of the sheet metal part 200, the first connecting member 301, the second connecting member 302 and the sheet metal part 200 are fastened together by the above-mentioned torque, thereby maintaining a continuous and stable connection between the three.

[0063] In some embodiments, the first connector 301 is a stud structure, and the stud head 3011a of the first connector 301 is clamped to the decorative component 100. The second connector 302 is a nut structure, and the second connector 302 is screwed to the threaded portion 3011b of the first connector 301.

[0064] The column head 3011a and the aforementioned abutment portion 3012 are spaced apart, and a portion of the decorative component 100 is accommodated within this space, thereby securing the decorative component 100 relative to the sheet metal member 200. More specifically, the decorative component 100 includes a main body portion 3011 and a connecting portion 102. The main body portion 101 and the sheet metal member 200 are stacked. The connecting portion 102 is provided with a socket hole 1021, which is socketed onto the main body portion 3011 of the first connecting member 301 located between the column head 3011a and the abutment portion 3012. In other words, the connecting portion 102 located around the socket hole 1021 is located within the aforementioned space.

[0065] In some embodiments, the trim 100 , the sheet metal component 200 , and the second connecting component 302 are sequentially arranged in a direction from the outside to the inside of the vehicle body structure.

[0066] That is to say, the above-mentioned body structure is applied to a vehicle, the trim 100 can be used as an interior layer inside the exterior sheet metal layer of the vehicle, and the sheet metal 200 can be used as an internal sheet metal layer inside the interior layer of the vehicle. By setting the above-mentioned connection component 300, the sealing between the interior layer and the internal sheet metal layer of the vehicle can be ensured, and impurities including but not limited to water can be prevented from entering the interior of the vehicle from the outside of the vehicle.

[0067] In some embodiments, the vehicle body structure includes a plurality of connection assemblies 300, and the trim 100 and the sheet metal part 200 are connected via the plurality of connection assemblies 300. Figure 4 As shown, the decorative part 100 and the sheet metal part 200 are connected by three connecting components 300, which can improve the connection strength between the two. The three connecting components 300 can be located at the three vertices of the same triangle.

[0068] Another object of an embodiment of the present application is to provide a vehicle, which includes a vehicle body structure as described in any one of the above items.

[0069] The vehicle provided in the embodiment of the present application adopts the body structure provided in the present application. By designing the first connecting member 301 in the body structure so that the first ring portion 3012a thereof abuts against the sheet metal part 200, a rigid contact between the first connecting member 301 and the sheet metal part 200 can be provided. Through this rigid contact, the stability of the relative position of the first connecting member 301 and the sheet metal part 200 after being fixed is ensured, thereby ensuring the stability of the relative position of the decorative part 100 and the sheet metal part 200, and improving the stability, durability and safety of the body structure during use.

[0070] In addition, the vehicle provided in the embodiment of the present application has the sealing ring 303 in its body structure clamped between the second ring portion 3012b and the corresponding sheet metal 200. The above-mentioned rigid contact further ensures the configuration reliability of the sealing ring 303, and can ensure that the sealing ring 303 is continuously and firmly clamped between the second ring portion 3012b and the sheet metal 200, thereby ensuring the sealing between the decorative part 100 and the sheet metal 200, preventing impurities on the outside of the decorative part 100 from entering the interior of the vehicle, such as preventing water leakage, thereby improving the waterproofness and reliability of the vehicle.

[0071] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
