[0001] The utility model relates to the technical field of automobile sheet metal, and more specifically to an automobile sheet metal component which is easy to install. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates, including shearing, punching, cutting, compounding, folding, welding, riveting, splicing and forming. Its notable feature is that the thickness of the same part is consistent. The products processed by sheet metal technology are called sheet metal parts. As a very common means of transportation, cars have brought great convenience to people. Many parts of cars are sheet metal parts, including doors, roofs, window frames, hoods, trunk lids, etc. Automobile sheet metal is usually made of steel, aluminum alloy or other special alloys. In automobile manufacturing, the shape of sheet metal parts is made by stamping and die, which can ensure that they meet the design requirements. Due to the limitations of stamping and die technology and the consideration of easy installation and disassembly, automobile sheet metal parts cannot be formed in one piece. They are often set as multiple sheet metal parts and then installed as one. It is necessary to set a special installation structure on the sheet metal to achieve the connection between different sheet metal parts.

[0024] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0025] Example 1

[0026] like Figure 1 As shown, an automobile sheet metal component that is easy to install is characterized in that it includes a first sheet metal part 1 and a second sheet metal part 2. The first sheet metal part 1 and the second sheet metal part 2 are connected by a connecting structure 3. The connecting structure 3 includes a connecting rod 31 and a connecting hole 32. The connecting rod 31 is fixed at the edge of the first sheet metal part 1. The connecting hole 32 is opened at the edge of the second sheet metal part 2. The connecting rod 31 can be inserted into the connecting hole 32. The second sheet metal part 2 is also provided with a fixing structure 4 for connecting with the connecting rod 31. The fixing structure 4 is arranged on one side of the connecting hole 32. The fixing structure 4 can be inserted into the connecting rod 31 and the connecting hole 32. The connecting structure 3 includes a connecting rod 31 and a connecting hole 32. The connecting rod 31 and the connecting hole 32 are installed on the side where the first sheet metal part 1 and the second sheet metal part 2 are connected. The position of the connecting hole 32 matches the position of the connecting rod 31. When the first sheet metal part 1 and the second sheet metal part 2 need to be installed together, the first sheet metal part 1 and the second sheet metal part 2 can be installed by simply inserting the connecting rod 31 of the first sheet metal part 1 into the connecting hole 32 of the second sheet metal part 2. Since the connecting rod 31 and the connecting hole 32 are easy to fall off, a fixing structure 4 is required to ensure that the connecting rod 31 entering the connecting hole 32 will not fall off from the connecting hole 32, thereby ensuring that the first sheet metal part 1 and the second sheet metal part 2 are installed firmly.

[0027] like Figure 1 ,3 As shown, a fixing groove 21 is also provided on the second sheet metal part 2, and the fixing groove 21 is located on one side of the connecting hole 32, and the fixing structure 4 is installed in the fixing groove 21. The fixing groove 21 is provided with a through hole 22, and the through hole 22 penetrates the fixing groove 21 and the connecting hole 32, and a fixing hole 311 is provided on the side of the connecting rod 31, and the fixing structure 4 can extend into the fixing hole 311 through the through hole 22. The fixing groove 21 is provided on the second sheet metal part 2, and the fixing structure 4 is installed in the fixing groove 21, so that the fixing structure 4 can be installed in the second sheet metal part 2, saving space for placing the fixing structure 4. The fixing groove 21 is provided with a through hole 22 that penetrates the connecting hole 32, and the connecting rod 31 is provided with a fixing hole 311, and the fixing structure 4 installed in the fixing groove 21 can extend into the connecting hole 32 through the through hole 22 and be inserted into the fixing hole 311. When the first sheet metal component 1 and the second sheet metal component 2 are about to be separated, the fixing hole 311 on the first sheet metal component 1 conflicts with the fixing structure 4 of the second sheet metal component 2 , thereby preventing the first sheet metal component 1 and the second sheet metal component 2 from being separated.

[0028] like Figure 1As shown, the fixed structure 4 includes a telescopic member 41, a limiting plate 42 and a supporting plate 43. The limiting plate 42 is installed in the fixing groove 21. The fixed end of the telescopic member 41 is installed on a side of the limiting plate 42 close to the connecting hole 42. The telescopic member 41 is aligned with the through hole 22. The supporting plate 43 is fixed on the telescopic end of the telescopic member 41. An elastic member 44 is arranged between the supporting plate 43 and the limiting plate 42. The two ends of the elastic member 44 are connected to the supporting plate 43 and the limiting plate 42 respectively. The limiting plate 42 is fixed in the fixing groove 21 to fix the position of the fixed structure 4. The fixed end of the telescopic member 41 is fixed on a side of the limiting plate 42 close to the connecting hole 32. When the telescopic member 41 is in the extended state, the telescopic end of the telescopic member 41 extends into the connecting hole 42 to fix the position of the connecting rod 31. When the telescopic member 41 is in the contracted state, the telescopic end of the telescopic member 41 retracts from the connecting hole 32, and the connecting rod 31 can be freely pulled out of the connecting hole 32. A support plate 43 is fixed on the telescopic end of the telescopic member 41, and the two ends of the elastic member 44 are connected to the limit plate 42 and the support plate 43 respectively. The limit plate 42 is in a fixed state and cannot be moved, and the elastic member 44 is in a compressed state, which can continuously provide elastic force to the support plate 43 so that the support plate 43 remains in contact with the bottom of the fixed groove 21, thereby making the telescopic end of the telescopic member 41 fixed to the support plate 43 remain in an extended state, and the telescopic end of the telescopic member 41 remains inserted into the connecting hole 42. When the first sheet metal member 1 is connected to the second sheet metal member 2, the connecting rod 31 on the first sheet metal member 1 is inserted into the connecting hole 32 of the second sheet metal member 2. When the connecting rod 31 is inserted to the position of the telescopic member 41, the outer wall surface of the connecting rod 31 conflicts with the telescopic end of the telescopic member 41, and the telescopic member 41 contracts. When the connecting rod 31 is inserted until the telescopic member 41 is aligned with the fixing hole 311 , under the action of the elastic member 44 , the telescopic end of the telescopic member 41 is inserted into the fixing hole 311 , thereby fixing the connecting rod 31 .

[0029] like Figure 1 As shown, a movable plate 45 for retracting the telescopic member 41 is also fixed on the limit plate 42. When the first sheet metal member 1 and the second sheet metal member 2 connected together need to be separated, the movable plate 45 is pulled to retract the telescopic member 41, and the telescopic end of the telescopic member 41 is retracted from the fixing hole 311, releasing the fixing of the fixing structure 4 to the connecting rod 31, so that the connecting rod 31 can be freely pulled out from the connecting hole 32.

[0030] like Figure 2As shown, one end of the movable plate 45 is fixed to a side of the support plate 43 away from the connection hole 42, and the movable plate 45 extends to a side of the limit plate 42 away from the connection hole 42, and the movable plate 45 is slidably connected to the limit plate 42. The support plate 43 is fixed to the telescopic end of the telescopic rod 41, and an elastic member 44 is connected to the support plate 43. In the absence of external force, the support plate 43 abuts against the bottom of the fixed groove 21 under the elastic force of the elastic member 44, so that the telescopic member 41 remains in an extended state. When the telescopic rod 41 needs to be retracted, the movable plate 45 is pulled to move in a direction away from the connection hole 32, which offsets the elastic force applied by the elastic member 44 to the support plate 43, so that the support plate 43 fixed to one end of the movable plate 45 moves, driving the telescopic end of the telescopic member 41 fixed to the support plate 43 to move, so that the telescopic member 41 is retracted, and the locking of the connecting rod 31 is released.

[0031] like Figure 2 As shown, the movable plate 45 is "L"-shaped, and the "L"-shaped movable plate 45 is divided into a first body and a second body, one end of the second body is connected to the support plate 43, and the other end of the second body extends out of the side of the limit plate 42 away from the connection hole 32 and is connected to the first body. If the movable plate 45 only has the second body, the movable plate 45 can only be pulled by applying pressure to the side of the movable plate 45 to generate friction to pull the movable plate 45 to move. Due to the low efficiency of converting pressure into friction, the movable plate 45 is difficult to pull. One end of the second body is connected to the first body, and the second body is perpendicular to the first body. When pulling the movable plate 45, only the first body needs to be pulled, and the force applied to the first body can be fully used to pull the movable plate 45 to move, making it easier to pull the movable plate 45.

[0032] Example 2

[0033] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, a sealing component 5 is also provided at the bottom of the fixing groove 21. The function of the sealing component 5 is to seal the fixing groove 21 to protect the fixing component 4 installed in the fixing groove 21 and improve the aesthetics of the second sheet metal part 2 of the automobile.

[0034] like Figure 2As shown, the sealing assembly 5 includes a sealing plate 51, which is placed in the notch of the fixing groove 21, a rubber ring 52 is fixed to the outer peripheral wall of the sealing plate 51, a side of the limiting plate 52 away from the telescopic member 41 is fixedly connected to a support rod 53, and a side of the sealing plate 51 close to the movable plate 45 is provided with a support hole 54, and the support rod 53 extends to the inside of the support hole 54. The rubber ring 52 fixed to the outer peripheral wall of the sealing plate 51 is elastic and can completely fit the inner wall surface of the fixing groove 21 to achieve a sealing effect. At the same time, the surface of the rubber ring 52 is rough, which can provide friction to fix the position of the sealing plate 51. At the same time, the characteristic of the rubber ring 52 that is easy to deform makes it easy for the friction between it and the inner wall surface of the fixing groove 21 to be too large, and it is easy to disassemble the sealing plate 21 to operate the fixing assembly 4. A support rod 53 is fixedly connected to the side of the limit plate 42 away from the telescopic member 41, and a support hole 54 is opened on the side of the sealing plate 51 close to the movable plate 45. The support rod 53 extends into the support hole 54. The support rod 53 cooperates with the support hole 54 to ensure that the position of the sealing plate 51 will not be offset.

[0035] Example 3

[0036] This embodiment is similar to the above-mentioned embodiment 1, except that: Figure 1 As shown, the connecting rod 31 is gap-connected with the connecting hole 32. This arrangement ensures that the connecting rod 31 can move freely in the connecting hole 32, and avoids the connecting rod 31 being stuck in the connecting hole 32 and unable to be inserted or pulled out, resulting in the first sheet metal part 1 and the second sheet metal part 2 not being installed in place or the first sheet metal part 1 and the second sheet metal part 2 being unable to be disassembled.

[0037] like Figure 1 As shown, a rubber ring 33 is also provided in the connection hole 32, and the connection rod 31 can pass through the rubber ring 33. Since the connection rod 31 is connected with the connection hole 32 with a gap, the connection rod 31 is prone to radial movement in the connection hole 32, resulting in an unstable connection. The connection hole 32 is provided with a rubber ring 33, and the inner ring surface of the rubber ring 33 is in close contact with the outer wall surface of the connection rod 31, providing radial support force for the connection rod 31, thereby preventing the connection rod 31 from radial movement in the connection hole 32.

[0038] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
