Description

Technical Field

[0001] This utility model relates to the field of vehicle body structure technology, and in particular to a vehicle body structure. Additionally, this utility model also relates to a vehicle. Background Technology

[0002] In existing vehicle body structures, sill beams and vehicle floors are typically made of steel and are welded together. However, with the development of new materials technology, lightweight composite materials such as carbon fiber are being widely used in the manufacture of vehicle body structural components.

[0003] In some split-type vehicle body structures, the sill beams made of composite materials and the vehicle floor made of steel sheet metal are usually assembled by splicing and bonding due to limitations in the forming process and unsuitability for welding.

[0004] However, during vehicle performance analysis and testing, the adhesive layer at the joint between the sill beam and the vehicle floor is prone to detachment, leading to assembly failure. Even with increased adhesive area, detachment cannot be prevented, and the connection effect cannot be improved. Delamination of the adhesive layer will prevent the fiber structure of the sill beam and the sheet metal structure of the vehicle floor from fulfilling their corresponding assembly connection function in the joint area. Utility Model Content

[0005] In view of this, the present invention aims to provide a vehicle body structure that offers an assembly and connection scheme suitable for door sill beams and vehicle floors made of different materials.

[0006] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0007] A vehicle body structure includes a sill beam and a vehicle floor located inside the sill beam;

[0008] The inner wall of the sill beam is provided with a slot, which is adapted to the side part of the vehicle floor, and the side part is inserted into the slot.

[0009] Furthermore, the sill beam is made of carbon fiber composite material, and / or the sill beam is integrally formed by hot pressing.

[0010] Furthermore, it also includes an assembly strip disposed on the inner sidewall, and the slot is disposed on the assembly strip.

[0011] Furthermore, the assembly strip has a base plate and side plates respectively connected to both sides of the base plate, the base plate and the side plates forming the slot; the base plate is fixed to the inner side wall, and the side portion inserted into the slot is clamped between the two side plates.

[0012] Furthermore, the base plate is fixed to the bottom of the inner sidewall via a connector.

[0013] Furthermore, along the length direction of the threshold beam, a plurality of connecting holes are provided at intervals on the inner sidewall; the connecting members are a plurality of those provided corresponding to each connecting hole, and each connecting member penetrates the bottom plate and is fastened in the corresponding connecting hole.

[0014] Furthermore, the connector has a head located within the slot, and a groove is formed on the portion of the base plate that penetrates the connector, with the head at least partially located within the groove.

[0015] Furthermore, the side portion is bonded to the inner wall of the slot, and / or the mounting strip is bonded to the inner side wall.

[0016] Furthermore, the width of the slot gradually increases from the bottom of the slot towards the opening of the slot.

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

[0018] (1) The vehicle body structure of this utility model has slots on the inner sidewalls of the sill beams, allowing the side portion of the vehicle floor to be inserted, forming a good insertion structure that enables the vehicle floor to be assembled and connected to the sill beams. The slots restrict the vertical movement of the vehicle floor, while the sill beams on both sides of the vehicle limit the vehicle floor in the lateral direction, thus allowing the vehicle floor to be easily and securely assembled into the vehicle body floor structure. Especially when the sill beams and the vehicle floor are made of different materials, the sill beams are not suitable for welding and fixed to the vehicle floor. The above-mentioned insertion structure can effectively solve the assembly problem of the vehicle floor and the sill beams, thus providing an assembly and connection solution suitable for sill beams and vehicle floors made of different materials.

[0019] (2) The hot-pressing process is used for one-piece molding, which can effectively process the internal cavity structure of the sill beam, ensuring that the sill beam has good structural performance and lightweight effect. Especially with the continuous development of materials technology, new composite materials such as carbon fiber are widely used in the manufacturing of vehicle structural components. The vehicle floor with sheet metal structure and the sill beam with composite materials such as carbon fiber cannot be assembled and connected by traditional welding processes. The body structure of this utility model can connect the sill beam and the vehicle floor through a plug-in method, which can effectively solve the assembly problem between sill beams and vehicle floors of different materials.

[0020] (3) Configuring an assembly strip for the sill beam and setting the slot on the assembly strip can effectively reduce the processing difficulty of the sill beam, realize the separate processing of the sill beam and the assembly strip, and then install the assembly strip on the sill beam, which can reduce the overall processing and manufacturing cost.

[0021] (4) The cross-section of the assembly strip adopts a "U" shaped structure, with the slot formed by the base plate and two side plates. The structure is simple and effective, and it is convenient for the assembly strip to be processed and formed. The side part of the vehicle floor can also be easily inserted into the slot between the two side plates.

[0022] (5) The base plate is fixed to the inner wall by bolts, rivets and other connectors. The connectors are easy to purchase and equip, the installation and operation are simple, and the connection between the assembly strip and the sill beam can be guaranteed.

[0023] (6) Multiple connecting holes are spaced apart on the inner sidewall, and corresponding through holes are provided on the bottom plate of the assembly strip. The connector passes through the through holes on the bottom plate and the connecting holes on the inner sidewall, which can effectively achieve the fixed connection between the assembly strip and the sill beam. The head of the connector is hidden in the slot, and the end of the connector is hidden in the inner cavity of the sill beam, avoiding the connector from being exposed, thereby ensuring the external regularity of the vehicle body structure.

[0024] (7) A groove is machined at the through hole on the base plate to accommodate the head of the connector. This avoids the head from protruding at the bottom of the slot, which helps to achieve a tight fit between the side part and the base plate, thereby improving the insertion stability between the vehicle floor and the mounting strip.

[0025] (8) Based on the insertion, adhesive is used to bond the assembly strip and the inner side wall, as well as the side part of the vehicle floor and the slot. This can further improve the connection between the assembly strip and the sill beam, and between the vehicle floor and the assembly strip. With the combined effect of the fastening of the connector, the insertion of the vehicle floor and the assembly strip, and the adhesive, the assembly connection strength between the vehicle floor and the sill beam is effectively guaranteed while ensuring the convenient installation of the vehicle floor.

[0026] (9) The slot is designed with a larger flared opening to facilitate smooth insertion of the side part. The side plate can guide the side part when the slot is inserted into the side part, making the insertion operation of the vehicle floor more convenient and efficient.

[0027] Another objective of this invention is to provide a vehicle employing the body structure described herein. The vehicle of this invention possesses the technical advantages of the aforementioned body structure. Attached Figure Description

[0043] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0044] Example 1

[0045] This embodiment relates to a vehicle body structure, providing an assembly and connection scheme suitable for sill beams 1 and vehicle floor 2 made of different materials; one exemplary structure is as follows: Figure 1 , Figure 2 and Figure 3 As shown.

[0046] Overall, the vehicle body structure includes a sill beam 1 and a vehicle floor 2 located inside the sill beam 1. The inner wall 11 of the sill beam 1 is provided with a slot 30, which is adapted to the side portion 200 of the vehicle floor 2, and the side portion 200 is inserted into the slot 30.

[0047] It should be noted that, based on the above-mentioned overall design concept, the technical solution of this utility model can adopt a variety of different specific implementation structures, forms, or configuration sequences. For example, the aforementioned sill beam 1 can be made of composite materials or commonly used steel profiles; the slot 30 can be integrally formed on the sill beam 1, or a separate assembly strip 3 can be designed, with the slot 30 set on the assembly strip 3, and then the assembly strip 3 installed on the sill beam 1. For parts required for the implementation of the overall solution but not covered in the above overall setup, reasonable and flexible designs can be made by referring to mature design methods in the field and the actual situation during implementation. The specific implementation schemes described below in this embodiment are only one of the many solutions that can be formed by the above-mentioned combinations and variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements based on the actual situation. Obviously, the various solutions that can be formed by the above-mentioned combinations and variations, as well as the specific implementation schemes of this embodiment, are all within the protection scope of this utility model.

[0048] Specifically, in this embodiment, the sill beam 1 is integrally formed using a hot-pressing process, and preferably made of lightweight carbon fiber composite material. The hot-pressing process allows for the efficient fabrication of the internal cavity 10 of the sill beam 1, ensuring good structural performance and lightweight design. Especially with the continuous development of materials technology, new composite materials such as carbon fiber are widely used in vehicle structural component manufacturing. Using carbon fiber and other composite materials, and employing autoclave molding to manufacture the sill beam 1, can effectively improve the lightweight design level of vehicles. In this case, the vehicle floor 2, which typically uses sheet metal structures, and the sill beam 1 cannot be assembled and connected using traditional welding processes. Therefore, the vehicle body structure of this invention uses a plug-in connection method to connect the sill beam 1 and the vehicle floor 2, effectively solving the assembly problem between sill beam 1 and vehicle floor 2 made of different materials.

[0049] like Figure 3 and combined Figure 4 , Figure 5As shown, in the vehicle body structure of this embodiment, an assembly strip 3 is also provided on the inner sidewall 11 of the sill beam 1. The aforementioned slot 30 can then be provided on the assembly strip 3. Configuring the assembly strip 3 on the sill beam 1 and providing the slot 30 on the assembly strip 3 effectively reduces the processing difficulty of the sill beam 1, allowing for separate processing of the sill beam 1 and the assembly strip 3. Afterwards, the assembly strip 3 is installed onto the sill beam 1, reducing the overall processing and manufacturing cost.

[0050] There are, of course, various structural options available for the specific configuration of the assembly strip 3. In this embodiment, such as... Figure 3 and combined Figure 5 , Figure 6 As shown, the assembly strip 3 has a base plate 300 and side plates 301 respectively connected to both sides of the base plate 300. The base plate 300 and the side plates 301 form a slot 30. The base plate 300 is fixed to the inner side wall 11, and the side portion 200 inserted into the slot 30 is clamped between the two side plates 301. The cross-section of the assembly strip 3 adopts a "U" shaped structure, with the base plate 300 and the two side plates 301 forming the slot 30. The structure is simple and effective, facilitating the processing and forming of the assembly strip 3. The side portion 200 of the vehicle floor 2 can also be easily inserted into the slot 30 between the two side plates 301.

[0051] Based on the above configuration, the base plate 300 can be fixed to the bottom of the inner wall 11 via the connector 4. The base plate 300 is fixed to the inner wall 11 using connectors such as bolts and rivets. The connectors 4 are easy to procure and equip, and the installation operation is simple. They can also ensure the reliability of the connection between the assembly strip 3 and the sill beam 1.

[0052] Preferably, multiple connecting holes 110 can be provided at intervals on the inner sidewall 11 along the length direction of the sill beam 1; simultaneously, multiple connectors 4 are provided corresponding to each connecting hole 110. Each connector 4 penetrates the base plate 300 and is fastened in its corresponding connecting hole 110. The specific configuration and number of connectors 4 and connecting holes 110 can be flexibly set within a reasonable range. Based on the length of the sill beam 1 and the specifications of the connectors 4, the reasonable spacing between two adjacent connecting holes 110 can be determined, thereby determining the number of connectors 4 and connecting holes 110.

[0053] Multiple connecting holes 110 are spaced apart on the inner sidewall 11, and corresponding through holes are provided on the base plate 300 of the mounting strip 3. The connector 4 passes through the through holes on the base plate 300 and the connecting holes 110 on the inner sidewall 11, which can effectively achieve the fixed connection between the mounting strip 3 and the sill beam 1. The head 40 of the connector 4 is hidden in the slot 30, and the end of the connector 4 is hidden in the inner cavity 10 of the sill beam 1, avoiding the connector 4 from being exposed, thereby ensuring the external regularity of the vehicle body structure.

[0054] It should be noted that the connector 4 is preferably made of rivet. Compared with the case where the connector 4 is made of screw, the connector hole 110 does not need to be made into a threaded hole, thus avoiding the situation where the threaded hole on the sill beam 1 is prone to stripping. If the connector 4 is made of screw, it is recommended to add a nut in the inner cavity 10 of the sill beam 1, so that the nut can be fitted into the corresponding position of the connector hole 110 for screw fastening with the connector 4.

[0055] like Figure 5 and Figure 6 As shown, the connector 4 in this embodiment includes a through-hole 41 for penetrating and connecting the base plate 300 and the inner sidewall 11, and a head 40 integrally formed at the end of the through-hole 41. When the connector 4 is inserted into place, the head 40 is located in the slot 30. Moreover, a recess 31 is formed on the portion of the base plate 300 of the mounting strip 3 through which the connector 4 passes, and the aforementioned head 40 is at least partially located in the recess 31. By machining the recess 31 at the through-hole on the base plate 300 and receiving the head 40 of the connector 4 into the recess 31, the head 40 can be prevented from protruding at the bottom of the slot 30, which is beneficial for achieving a tight fit between the side portion 200 and the base plate 300, thereby improving the insertion stability between the vehicle floor 2 and the mounting strip 3.

[0056] Furthermore, the aforementioned slot 30 can be designed as a straight slot with a rectangular cross-section, or as a slot structure with a larger opening and a flared cross-section. In this embodiment, as... Figure 6 As shown, the width of slot 30 gradually increases from the bottom towards the opening, making its cross-section roughly trumpet-shaped. Designing slot 30 with a large flared opening facilitates the smooth insertion of the side portion 200. The side plate 301 guides the side portion 200 during insertion, making the installation of the vehicle floor 2 more convenient and efficient. The specific inclination of the inner wall of the side plate 301 can be flexibly adjusted within a reasonable range, designed to ensure good guidance. For example, the inclination angle of the inner wall of the side plate 301 relative to the horizontal plane (i.e., the plane on which the vehicle floor 2 is located) can be set between 10° and 30°. A reasonable inclination angle ensures smooth insertion of the vehicle floor 2, solves fitting problems during assembly, and facilitates the application of adhesive to the inner wall of slot 30, allowing for better control of the appropriate adhesive layer thickness.

[0057] Of course, given the cross-sectional shape of the aforementioned slot 30, the side portion 200 of the vehicle floor 2 should also adopt a conformal shape to allow the side portion 200 to be tightly inserted into the slot 30, ensuring a close fit between the surface of the side portion 200 and the inner wall of the slot 30. In this embodiment, the vehicle floor 2 includes a hollow floor shell 20 and foam filler 21 filling the floor shell 20. This increases the thickness and sound insulation performance of the vehicle floor 2 while also improving its thermal insulation effect. Based on the above, the side portion 200 of the vehicle floor 2 can be integrally bent from the floor shell 20.

[0058] In addition, such as Figure 6 As shown, an adhesive layer can be applied between the vehicle floor 2 and the mounting strip 3, and between the mounting strip 3 and the sill beam 1, to reinforce the connection reliability between the sill beam 1 and the mounting strip 3, and between the vehicle floor 2 and the mounting strip 3, while improving the airtightness of the connection between the vehicle floor 2 and the sill beam 1. In this embodiment, the side portion 200 is bonded to the inner wall of the slot 30 via a second adhesive layer 51, and the base plate 300 of the mounting strip 3 is bonded to the inner side wall 11 via a first adhesive layer 50.

[0059] Based on the insertion, adhesive is used to bond the assembly strip 3 and the inner side wall 11, as well as the side part 200 of the vehicle floor 2 and the slot 30. This can further improve the connection between the assembly strip 3 and the sill beam 1, and between the vehicle floor 2 and the assembly strip 3. With the combined effect of the fastening of the connector 4, the insertion of the vehicle floor 2 and the assembly strip 3, and the adhesive, the assembly connection strength between the vehicle floor 2 and the sill beam 1 is effectively guaranteed while ensuring the convenient installation of the vehicle floor 2.

[0060] In summary, the vehicle body structure of this embodiment features a slot 30 on the inner wall 11 of the sill beam 1, into which the side portion 200 of the vehicle floor 2 is inserted, forming a good insertion structure that enables the vehicle floor 2 to be assembled and connected to the sill beam 1. The slot 30 restricts the vertical movement of the vehicle floor 2, while the sill beams 1 on both sides of the vehicle further restrict the vehicle floor 2 in the lateral direction, allowing the vehicle floor 2 to be easily and securely assembled into the vehicle body floor structure. Especially when the sill beam 1 and the vehicle floor 2 are made of different materials, welding is not suitable for fixing the sill beam 1 to the vehicle floor 2. The above-mentioned insertion structure effectively solves the assembly problem between the vehicle floor 2 and the sill beam 1, thus providing an assembly and connection solution suitable for sill beams 1 and vehicle floor 2 made of different materials.

[0061] Example 2

[0062] This embodiment relates to a vehicle, which adopts the body structure provided in Embodiment 1.

[0063] The vehicle body structure of this invention provides convenient assembly conditions for the carbon fiber composite material used in the sill beam 1. Compared to the existing structure, where the composite material sill beam 1 and the sheet metal vehicle floor 2 are assembled by splicing and bonding, the vehicle body structure of this invention has better assembly connection reliability. Existing composite material sill beam 1 and vehicle floor 2, constrained by structural form and process type, cannot be independently connected by welding, bolting, or other methods. When using splicing and bonding, the fiber structure and component structure do not play their corresponding role in the joint area, easily leading to adhesive layer detachment and failure; even increasing the adhesive area is difficult to achieve a good improvement.

[0064] In the vehicle body structure of this utility model, an assembly strip 3 with a slot 30 is installed on the composite material sill beam 1. The vehicle floor 2 and the assembly strip 3 are inserted into each other. The assembly strip 3 and the sill beam 1 are connected and fixed by a connector 4. At the same time, an adhesive layer is used to reinforce the connection between the assembly strip 3 and the sill beam 1, as well as between the assembly strip 3 and the vehicle floor 2. The connection form is changed from a single flexible adhesive to a multiple connection form with insertion and connection 4. The rigid connection structure and adhesive combination effectively improve the connection effectiveness between the vehicle floor 2 and the sill beam 1, reduce the risk of failure of the connection assembly structure between the vehicle floor 2 and the sill beam 1, and thus effectively improve the structural performance, stiffness and modal characteristics of the vehicle.

[0065] Furthermore, the use of an insert structure between the vehicle floor 2 and the sill beam 1 simplifies assembly and reduces the assembly complexity of the sill and floor structures. In the event of a collision, the impact force damages the vehicle floor, specifically the connection between the sill beam 1 and the vehicle floor 2. The damage changes from adhesive layer failure to failure of the rigid connection structure and mechanical connection, effectively improving the vehicle's impact resistance.

[0066] The above description is merely a preferred embodiment of this utility model. Detailed explanations of configurations, examples of specific structural arrangements, and descriptions of assembly and connection methods are provided to ensure sufficient disclosure so that those skilled in the art can better implement this utility model, and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
