Description

Technical Field

[0001] The utility model relates to the technical field of automobile roof covers, and particularly relates to an automobile roof cover structure. Background Art

[0002] The roof cover is the cover plate at the top of the carriage, generally including structures such as an outer roof panel, cross beams, and an interior trim panel. The cross beams play a supporting role in the roof cover. To ensure sufficient vehicle lightweighting, mostly two cross beams are provided, and the outer roof panel is made of a relatively thin metal plate.

[0003] Since the roof cover does not play a major role in compression resistance and support during vehicle driving, the overall structure of its outer roof panel is simple and thin. The structures of other parts of the vehicle have greater strength and sufficient rigidity to ensure the normal use of vehicle functions. When facing external impacts, other parts of the vehicle can provide better protection for passengers and drivers. However, this part of the vehicle roof cover, which is close enough to passengers and drivers, has insufficient compression resistance due to the pursuit of lightweighting, so it cannot protect passengers and drivers effectively and is easily damaged under the action of external impacts. Therefore, an automobile roof cover structure is proposed to solve the above-mentioned problems. Summary of the Utility Model

[0004] Based on the above description, the utility model provides an automobile roof cover structure to solve the problem of insufficient compression resistance of the existing outer roof panel.

[0005] The technical solution of the utility model to solve the above technical problems is as follows: an automobile roof cover structure, including: an outer roof panel, the outer roof panel includes a mounting frame, an elastic buffer plate is arranged between the mounting frames, and an elastic buffer member is arranged between the outer roof panel and the elastic buffer plate.

[0006] On the basis of the above technical solution, the utility model can be further improved as follows.

[0007] Further, the outer roof panel includes an outer panel main body and a bending end. Both ends of the outer panel main body are provided with bending ends. The surface of the bending end is provided with a reinforcing concave rib structure, and side edge metal sheets are arranged on the outer edges of the outer panel main body and the bending end.

[0008] Further, a reinforcing convex rib structure is arranged on the upper surface of the outer panel main body, a mounting frame is arranged on the lower surface of the outer panel main body, through holes are arranged on the surface of the mounting frame, and a fixing rod is arranged between the mounting frames through fixing bolts.

[0009] Further, the elastic buffer plate includes a buffer main board, the buffer main board is a corrugated metal plate, and the buffer main board includes an upper concave surface and a lower concave surface.

[0010] Further, a positioning side plate is provided on the upper surface of the buffer main board, and the positioning side plate is disposed at the upper concave surface.

[0011] Further, the fixing rod includes a main rod, the main rod is disposed inside the lower concave surface and is in contact with the surface of the lower concave surface, and threaded blind holes are provided at both ends of the main rod.

[0012] Further, the diameter of the main rod is greater than the diameter of the through hole, and the main rod is disposed between the mounting brackets.

[0013] Further, the fixing bolt includes a stress column, the stress column is disposed inside the through hole, a threaded column is provided on one side of the stress column close to the main rod, and the threaded column is threadedly connected to the threaded blind hole.

[0014] Further, a bolt head is provided on one side of the stress column away from the main rod, and the diagonal length of the bolt head is greater than the diameter of the through hole.

[0015] Further, the elastic buffer member is a rubber cylinder, and is disposed inside the upper concave surface and between the positioning side plates, and the surface of the elastic buffer member is in contact with the lower surface of the top cover outer plate.

[0016] Compared with the prior art, the technical solution of the present application has the following beneficial technical effects:

[0017] 1. By providing components such as the top cover outer plate, the elastic buffer plate, the fixing rod, and the fixing bolt, through the cooperation between the fixing rod and the fixing bolt, the fixing rod can be fixed between the mounting brackets, and under the action of the fixing rod, the elastic buffer plate can be fixed below the top cover outer plate, so that the elastic buffer plate can deform together when the top cover outer plate is subjected to an external force.

[0018] 2. By providing the elastic buffer plate and the elastic buffer member, the effect of buffering the external force is realized. When the top cover outer plate deforms under the action of an external force, the elastic buffer plate elastically deforms under the combined action of the fixing rod and the top cover outer plate, playing a preliminary buffering effect. In this process, the elastic buffer member is deformed by force, and further plays a role of secondary buffering, and the effect of reducing the damage degree of the external force on the top cover outer plate is achieved through secondary buffering.

The terms used in the description of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.

[0030] As used herein, the singular forms "a", "an" and "the" may also include the plural forms unless the context clearly dictates otherwise. It should also be understood that the terms "comprising" or "having" etc. specify the presence of the stated features, wholes, steps, operations, components, parts or combinations thereof, but do not preclude the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0031] Please refer toFigure 1 and Figure 4 As shown in Figure 4 , an automobile roof cover structure includes:

[0032] An outer roof panel 1, which includes an outer panel main body 11 and a bent end 13. Both ends of the outer panel main body 11 are provided with bent ends 13. A reinforcing concave rib structure 14 is arranged on the surface of the bent end 13. Side edge metal sheets 15 are arranged on the outer edges of both the outer panel main body 11 and the bent end 13;

[0033] A reinforcing convex rib structure 12 is arranged on the upper surface of the outer panel main body 11. An installation bracket 16 is arranged on the lower surface of the outer panel main body 11. Through holes are arranged on the surface of the installation bracket 16. A fixing rod 3 is arranged between the installation brackets 16 through fixing bolts 4;

[0034] Based on the above, both the reinforcing convex rib structure 12 and the reinforcing concave rib structure 14 play a role in increasing the strength of the outer roof panel 1, and the installation bracket 16 and the fixing bolts 4 cooperate with each other to play a role in fixing the fixing rod 3.

[0035] As Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown in Figure 6 , an elastic buffer plate 2 is arranged between the installation brackets 16. The elastic buffer plate 2 includes a buffer main board 21. The buffer main board 21 is a corrugated metal plate. The buffer main board 21 includes an upper concave surface 22 and a lower concave surface 23;

[0036] A positioning side plate 24 is arranged on the upper surface of the buffer main board 21. The positioning side plate 24 is arranged at the upper concave surface 22;

[0037] Based on the above, the buffer main board 21 plays a buffering role. When the outer roof panel 1 is stressed and deformed, it squeezes the buffer main board 21, causing the buffer main board 21 to deform together. The deformed buffer main board 21 generates an elastic force. In this process, the buffer main board 21 plays a preliminary buffering role, and when the external force disappears, the buffer main board 21 can return to its original state. The setting of the positioning side plate 24 limits the position of the elastic buffer member 5 when it is arranged at the upper concave surface 22, ensuring that the elastic buffer member 5 will not slide off from the side.

[0038] As Figure 2 , Figure 3 and Figure 7 As shown in Figure 7 , the fixing rod 3 includes a main rod 31. The main rod 31 is arranged inside the lower concave surface 23 and is in contact with the surface of the lower concave surface 23. Threaded blind holes 32 are arranged at both ends of the main rod 31. The diameter of the main rod 31 is larger than the diameter of the through hole. The main rod 31 is arranged between the installation brackets 16;

[0039] The fixing bolt 4 includes a stress column 41 disposed inside the through hole. A threaded column 42 is provided on one side of the stress column 41 close to the main rod 31, and the threaded column 42 is threadedly connected to the threaded blind hole 32. A bolt head 43 is provided on the side of the stress column 41 away from the main rod 31, and the diagonal length of the bolt head 43 is greater than the diameter of the through hole.

[0040] Based on the above, the fixing rod 3 is fixed between the mounting brackets 16 by the fixing bolts 4. During this process, the fixing rod 3 is located inside the concave surface 23, which realizes the fixing of the buffer main board 21. And when the top cover main board 1 is deformed, the buffer main board 21 is elastically deformed together through the mounting brackets 16 and the fixing rod 3.

[0041] As Figure 2 and Figure 3 shown, the elastic buffer member 5 is disposed between the top cover outer plate 1 and the elastic buffer plate 2. The elastic buffer member 5 is a rubber cylinder and is disposed inside the upper concave surface 22 and between the positioning side plates 24. The surface of the elastic buffer member 5 is in contact with the lower surface of the top cover outer plate 1.

[0042] Based on the above, the elastic buffer member 5 is disposed between the positioning side plates 24. When the top cover outer plate 1 and the elastic buffer plate 2 are deformed, the elastic buffer member 5 is deformed, thereby realizing the effect of secondary buffering.

[0043] When this embodiment is actually used, after the elastic buffer member 5 is disposed inside the upper concave surface 22, the elastic buffer plate 2 is fixed between the mounting brackets 16 by the fixing bolts 4 and the fixing rod 3. During this process, both the elastic buffer member 5 and the elastic buffer plate 2 are in contact with the lower surface of the top cover outer plate 1.

[0044] When the automobile top cover is subjected to an external impact, the top cover will be deformed, and there are the following two situations of deformation:

[0045] 1. Elastic deformation occurs, that is, when the automobile top cover is subjected to a small external force and undergoes slight deformation. At this time, after the external force disappears, the automobile top cover will return to its original state. During this process, after the top cover outer plate 1 is deformed, it will drive the mounting brackets 16, the fixing bolts 4, and the fixing rod 3 to move together. After the movement, the elastic buffer plate 2 and the elastic buffer member 5 are squeezed, so that both the elastic buffer plate 2 and the elastic buffer member 5 undergo elastic deformation. The deformation process is the buffering process. And when the external force disappears, the elastic buffer plate 2 and the elastic buffer member 5 return to their original states under the action of elastic potential energy.

[0046] 2. When the impact force is large enough to cause the complete deformation of the car roof, during this process, after the outer roof panel 1 is deformed by the force, the elastic buffer plate 2 is deformed through the mounting bracket 16, the fixing bolt 4 and the fixing rod 3. On the one hand, the elastic buffer plate 2 can strengthen the strength of the roof, making the external force required for the roof to deform greater. On the other hand, when the outer roof panel 1 deforms, it squeezes the elastic buffer plate 2, causing the elastic buffer plate 2 to deform together. During the deformation process, the elastic buffer plate 2 will stretch or contract, and at this time, it plays a buffering role to reduce the impact of the instantaneous impact force on the car passengers and drivers. At the same time, the elastic buffer member 5 is deformed by the force, achieving a further buffering effect;

[0047] Through the settings of the mounting bracket 16, the fixing bolt 4 and the fixing rod 3, the elastic buffer plate 2 and the elastic buffer member 5 can be easily disassembled and installed, and the overall structures of the elastic buffer plate 2 and the elastic buffer member 5 are simple and light. Without significantly increasing the overall weight of the car roof, the compressive strength of the car roof can be greatly improved to enhance the protection ability for the driver and passengers.

[0048] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
