Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a frame structure provided with an outer covering plate and an automobile. Background Art

[0002] In the automobile structure, there are many frame structural parts and external decorative panels. At present, some external decorative panels are fixed to the frame structure by installing standard parts and fixing them to the frame due to usage requirements. Due to the complexity of the vehicle's operating conditions, some larger structural parts arranged above the frame and spanning the left and right frame longitudinal beams, such as the rear power battery frame and other similar parts, will cause torsional deformation of the frame structure under some harsh working conditions due to the torsional deformation of the chassis (a certain degree of vertical height difference between the left and right frames), especially the middle part of the front and rear surfaces of the frame structure, which in turn affects the external covering panels fixed to it, causing local deformation in the vertical direction. In this case, factors such as the frame stiffness or insufficient yield strength of the external covering panels may cause damage and cracking of the external covering due to excessive local stress around the fixing points of the larger deformation areas.

[0003] In related technologies, two methods can be used to solve the above-mentioned deformation and cracking: increasing the frame stiffness or increasing the yield strength of the outer cover. However, both of the above methods will increase the weight and cost of the two components, which is not conducive to vehicle lightweighting and cost control requirements. Summary of the Invention

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0035] In the related art, the local deformation of the frame causes the outer cover connected to the frame to be damaged and cracked around the connection point at the part with greater deformation due to excessive local stress.

[0036] In a first aspect, the present application provides a frame structure provided with an outer covering plate, which comprises: a frame body 1, an outer covering plate 2 and at least one buffer assembly; wherein,

[0037] An outer covering panel 2 is connected to the frame body 1; at least one buffer component, part of which is movably connected to the outer covering panel 2 and the other part is connected to the frame body 1 to apply a clamping force to the outer covering panel 2 in the direction close to the frame body 1, and the buffer component can move relative to the outer covering panel 2 as the frame body 1 deforms.

[0038] It is worth noting that, by arranging a buffer component between the frame body 1 and the outer covering panel 2, the present application can generate relative displacement between the frame fixing point and the outer covering panel fixing point when the frame is deformed under harsh working conditions, thereby eliminating or partially eliminating the excessive local stress of the panel caused by the deformation of the frame, so that the panel does not crack, and at the same time, it can limit the displacement of the panel in the direction perpendicular to the outer surface of the panel, thereby eliminating or reducing the local stress of the panel without increasing the rigidity of the frame and changing the material of the outer covering panel (increasing the yield strength).

[0039] Furthermore, the buffer assembly is installed in the area of ​​the frame body 1 where the deformation is greater, and a mounting hole is provided in the area of ​​the frame body 1 where the deformation is smaller, and is fixedly connected to the outer cover plate 2 through the mounting hole. Figure 2 and Figure 3As shown, the mounting hole is generally provided in the middle of the frame body 1 .

[0040] In some optional embodiments, Figure 2 and Figure 3 As shown, the buffer assembly includes: a roller box device, which is connected to the frame body 1, and the roller box device is partially supported by the outer covering plate 2, and can roll along the outer covering plate 2 as the frame body 1 deforms.

[0041] It can be understood that the roller rolling structure of the roller box device can reduce the damage to the surface of the outer covering plate 2 compared with other sliding structures.

[0042] Specifically, if Figure 1 As shown, the roller box device includes: an outer roller box component 4 and an inner roller box component 5; wherein,

[0043] The outer roller box assembly 4 is abutted against the outer side surface of the outer covering panel 2 and is in rolling engagement with the outer side surface of the outer covering panel 2; the inner roller box assembly 5 is located between the inner side surface of the outer covering panel 2 and the frame body 1, and the inner roller box assembly 5 partially passes through the outer covering panel 2 and is press-fitted with the outer roller box assembly 4. One side of the inner roller box assembly 5 is in rolling engagement with the inner side surface of the outer covering panel 2, and the other side is connected to the frame body 1.

[0044] It is worth noting that the inner roller box assembly 5 is fixedly connected to the frame body 1. During operation, the frame body 1 and the inner roller box assembly 5 do not move relative to each other. Therefore, when the frame body 1 is deformed, the inner roller box assembly 5 is driven to move along the outer covering panel 2. At the same time, the movement of the inner roller box assembly 5 drives the outer roller box assembly 4 and the outer covering panel 2 to move relative to each other. On the one hand, the outer roller box assembly 4 is used to press the outer covering panel 2 to limit the displacement of the outer covering panel 2 in a direction perpendicular to the outer surface of the outer covering panel 2. On the other hand, relative displacement is generated between the fixed points of the frame body 1 and the fixed points of the outer covering panel 2, thereby eliminating or partially eliminating the excessive local stress on the panel caused by frame deformation, so that the outer covering panel 2 does not crack.

[0045] In some preferred embodiments, Figure 1 As shown, a connecting bolt 6 is provided in the inner roller box assembly 5, one end of the connecting bolt 6 is pressed onto the outer roller box assembly 4, and the other end passes through the outer roller box assembly 4 and the outer covering plate 2 in sequence and is connected to the inner roller box assembly 5.

[0046] It can be understood that when the connecting bolt 6 is tightened, the connecting bolt 6 is fixedly connected to the inner roller box assembly 5, and at the same time, the nut at the other end of the connecting bolt 6 also presses the outer roller box assembly 4 to limit the outer covering panel 2 from moving toward its outer side surface.

[0047] In some optional implementations, the outer covering plate 2 is provided with a fixing hole 21 for the connecting bolt 6 to pass through, and the fixing hole 21 is clearance-fitted with the connecting bolt 6 .

[0048] It is worth noting that the fixing hole 21 can be an oblong hole. When the frame body 1 is deformed, the connecting bolt 6 is driven to move in the oblong hole, thereby eliminating the stress on the outer covering plate 2.

[0049] In some specific implementations, such as Figure 4 and Figure 5 As shown, the inner roller box assembly 5 includes: an inner bottom box 51 and an inner top box 54; wherein,

[0050] An inner bottom box 51 is provided with an inner roller portion 52 on its inner side, and a positioning boss 53 is provided on the outer side of the inner bottom box 51. The positioning boss 53 is passed through the frame body 1 and is limitedly engaged with the frame body 1. A threaded hole that cooperates with the connecting bolt 6 is provided in the positioning boss 53; an inner top box 54 is detachably connected to the inner side of the inner bottom box 51 by screws 8, and an inner window 531 is provided on the inner top box 54 for the inner roller portion 52 to pass through.

[0051] It is understandable that the positioning boss 53 is inserted into the frame body 1 and is limitedly engaged with the frame body 1. Furthermore, the positioning boss 53 is provided with an internal threaded hole, which is threadedly connected to the connecting bolt 6.

[0052] In some optional embodiments, Figure 6 and Figure 7 As shown, the outer roller box assembly 4 includes: an outer bottom box 41 and an outer top box 43; wherein,

[0053] The outer bottom box 41 has an outer roller portion 42 on its inner side, and the outer side of the outer bottom box 41 abuts against the connecting bolt 6; the outer top box 43 is detachably connected to the inner side of the outer bottom box 41, and the outer top box 43 is provided with an outer window 431 for the outer roller portion 42 to pass through.

[0054] Preferably, a positioning notch 532 is provided on the inner top box 54 , and an outer positioning boss 432 is provided on the outer top box 43 , and the outer positioning boss 432 is limitedly engaged with the positioning notch 532 .

[0055] It is worth noting that the outer positioning boss 432 is limitedly matched with the positioning notch 532 so that the minimum distance between the outer roller portion 42 in the outer roller box assembly 4 and the inner roller portion 52 in the inner roller box assembly 5 matches the thickness of the outer covering panel 2.

[0056] In some preferred embodiments, a backing plate 7 is provided on the frame body 1, and the backing plate 7 is located between the frame body 1 and the outer covering plate 2. Furthermore, the backing plate 7 can be attached to the frame body 1 by bonding or welding.

[0057] It should be noted that the pad 7 is installed in an area of ​​the frame body 1 that is substantially not deformed, and the outer surface of the pad 7 is flush with the outermost surface of the inner roller portion 52 of the inner roller box assembly 5 .

[0058] In a second aspect, the present application provides an automobile, comprising: a frame structure provided with an outer covering plate, comprising: a frame body 1, an outer covering plate 2 and at least one buffer assembly; wherein,

[0059] An outer covering panel 2 is connected to the frame body 1; at least one buffer component, part of which is movably connected to the outer covering panel 2 and the other part is connected to the frame body 1 to apply a clamping force to the outer covering panel 2 in the direction close to the frame body 1, and the buffer component can move relative to the outer covering panel 2 as the frame body 1 deforms.

[0060] It is worth noting that, by arranging a buffer component between the frame body 1 and the outer covering panel 2, the present application can generate relative displacement between the frame fixing point and the outer covering panel fixing point when the frame is deformed under harsh working conditions, thereby eliminating or partially eliminating the excessive local stress of the panel caused by the deformation of the frame, so that the panel does not crack, and at the same time, it can limit the displacement of the panel in the direction perpendicular to the outer surface of the panel, thereby eliminating or reducing the local stress of the panel without increasing the rigidity of the frame and changing the material of the outer covering panel (increasing the yield strength).

[0061] Furthermore, the buffer assembly is installed in the area of ​​the frame body 1 where the deformation is greater, and a mounting hole is provided in the area of ​​the frame body 1 where the deformation is smaller, and is fixedly connected to the outer cover plate 2 through the mounting hole. Figure 2 and Figure 3 As shown, the mounting hole is generally provided in the middle of the frame body 1 .

[0062] In some optional embodiments, Figure 2 and Figure 3 As shown, the buffer assembly includes: a roller box device, which is connected to the frame body 1, and the roller box device is partially supported by the outer covering plate 2, and can roll along the outer covering plate 2 as the frame body 1 deforms.

[0063] It can be understood that the roller rolling structure of the roller box device can reduce the damage to the surface of the outer covering plate 2 compared with other sliding structures.

[0064] Specifically, if Figure 1As shown, the roller box device includes: an outer roller box component 4 and an inner roller box component 5; wherein,

One side of the inner roller box assembly 5 is in rolling engagement with the inner side surface of the outer covering panel 2, and the other side is connected to the frame body 1.

[0066] It is worth noting that the inner roller box assembly 5 is fixedly connected to the frame body 1. During operation, the frame body 1 and the inner roller box assembly 5 do not move relative to each other. Therefore, when the frame body 1 is deformed, the inner roller box assembly 5 is driven to move along the outer covering panel 2. At the same time, the movement of the inner roller box assembly 5 drives the outer roller box assembly 4 and the outer covering panel 2 to move relative to each other. On the one hand, the outer roller box assembly 4 is used to press the outer covering panel 2 to limit the displacement of the outer covering panel 2 in a direction perpendicular to the outer surface of the outer covering panel 2. On the other hand, relative displacement is generated between the fixed points of the frame body 1 and the fixed points of the outer covering panel 2, thereby eliminating or partially eliminating the excessive local stress on the panel caused by frame deformation, so that the outer covering panel 2 does not crack.

[0067] In some preferred embodiments, Figure 1 As shown, a connecting bolt 6 is provided in the inner roller box assembly 5, one end of the connecting bolt 6 is pressed onto the outer roller box assembly 4, and the other end passes through the outer roller box assembly 4 and the outer covering plate 2 in sequence and is connected to the inner roller box assembly 5.

[0068] It can be understood that when the connecting bolt 6 is tightened, the connecting bolt 6 is fixedly connected to the inner roller box assembly 5, and at the same time, the nut at the other end of the connecting bolt 6 also presses the outer roller box assembly 4 to limit the outer covering panel 2 from moving toward its outer side surface.

[0069] In some optional implementations, the outer covering plate 2 is provided with a fixing hole 21 for the connecting bolt 6 to pass through, and the fixing hole 21 is clearance-fitted with the connecting bolt 6 .

[0070] It is worth noting that the fixing hole 21 can be an oblong hole. When the frame body 1 is deformed, the connecting bolt 6 is driven to move in the oblong hole, thereby eliminating the stress on the outer covering plate 2.

[0071] In some specific implementations, such as Figure 4 and Figure 5 As shown, the inner roller box assembly 5 includes: an inner bottom box 51 and an inner top box 54; wherein,

[0072] An inner bottom box 51 is provided with an inner roller portion 52 on its inner side, and a positioning boss 53 is provided on the outer side of the inner bottom box 51.
