Description

Technical Field

[0001] The invention relates to the technical field of sheet metal parts, and in particular to an automobile spliced ​​sheet metal part. Background Art

[0002] Sheet metal is a processing technology. Sheet metal has not yet had a relatively complete definition. According to a definition in a foreign professional journal, it can be defined as: Sheet metal is a comprehensive cold processing technology for metal sheets (usually less than 6mm), including shearing, punching / cutting / compounding, folding, riveting, splicing, forming (such as car body), etc.

[0003] There are many sheet metal parts in a car. Although most of the connection points are fixed by welding, the rest are mostly fixed by bolts and nuts. Relatively speaking, this connection method requires a certain amount of operating space and the turning of bolts and nuts, which cannot quickly achieve the quick connection of sheet metal parts.

[0004] Patent "CN202222770346.2" involves connecting a first sheet metal part with a second sheet metal part, but the structure between the first sheet metal part and the second sheet metal part is relatively complex and delicate, which is not conducive to quick connection. Summary of the invention

[0005] In order to solve the above problems, the present invention discloses an automobile splicing sheet metal part, in which a connector and a sleeve fastener are inserted and fastened on the folded edges of a first sheet metal part and a second sheet metal part, and the connector and the sleeve fastener are both formed by punching and bending of a plate, and a rubber ring is arranged between the first sheet metal part and the second sheet metal part. The plug-in and the sleeve fastener are used to connect the first sheet metal part and the second sheet metal part, and the use of the rubber ring allows a distance between the first sheet metal part and the second sheet metal part to avoid friction between the first sheet metal part and the second sheet metal part due to vibration, and to achieve tensioning after the connector and the sleeve fastener are connected.

[0006] The connector includes a first plate body, the first plate body is bent into a cylindrical shape, a connecting rod is arranged at the upper end of the first cylindrical plate body, a second side ear is bent at the upper side wall of the connecting rod, and a chamfer is arranged at the upper part of the second side ear. The connector is punched in advance and then bent.

[0007] The buckle piece includes a second plate body, the second plate body is bent into a cylindrical shape, a plurality of convex teeth are arranged on the upper end of the cylindrical second plate body, and the convex teeth are bent inward to form a conical surface section. Similarly, the buckle piece and the connector are produced in the same way.

[0008] Preferably, the lower end of the first cylindrical plate is bent to form a first side ear, and a first hoop is sleeved below the first side ear. Since the plate is bent, the first hoop prevents the first cylindrical plate from breaking.

[0009] Preferably, the lower end of the second cylindrical plate is bent to be provided with a third side ear, and a second hoop is sleeved below the third side ear. Similarly, the second hoop is also provided to prevent the second cylindrical plate from breaking.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. The connector and the sleeve fastener are fixedly connected by interlacing, that is, the second side ear passes through and abuts against the conical surface section to achieve fixation, which has the advantage of fast connection.

[0012] 2. A rubber ring is provided, and the rubber ring is located between the first sheet metal part and the second sheet metal part to avoid friction and provide tensioning effect for the connector and the buckle.

[0013] 3. The connector and the sleeve fastener are both produced by stamping and bending, and are sleeved by the first hoop and the second hoop to improve the stability of the connection. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figures 1 to 4 As shown, a spliced ​​sheet metal part for automobile is provided with a connector 1 and a sleeve fastener 5 inserted and fastened on the folded edges of a first sheet metal part 6 and a second sheet metal part 7. The connector 1 and the sleeve fastener 5 are both formed by punching and bending of plate parts. After the connector 1 passes through the preset through holes on the first sheet metal part 6 and the second sheet metal part 7, it passes through the sleeve fastener 5 again to be fastened together. A rubber ring 3 is provided between the first sheet metal part 6 and the second sheet metal part 7. The rubber ring 3 is provided so that a distance is set between the first sheet metal part 6 and the second sheet metal part 7. If vibration occurs, the first sheet metal part 6 and the second sheet metal part 7 can be prevented from rubbing against each other. At the same time, the rubber ring 3 is elastic and provides tension for the fastening of the connector 1 and the sleeve fastener 5.

[0023] The connector 1 includes a first plate body 11, which is bent into a cylindrical shape. A connecting rod 13 is provided at the upper end of the cylindrical first plate body 11. The upper side wall of the connecting rod 13 is bent to provide a second side ear 14, and the upper part of the second side ear 14 is provided with a chamfer. The buckle 5 includes a second plate body 52, which is bent into a cylindrical shape. A plurality of convex teeth are provided at the upper end of the cylindrical second plate body 52, and the convex teeth are bent inward to form a conical surface section 53.

[0024] When in use, the connecting rod 13 passes through the cylindrical second plate 52, and the second side ear 14 passes over the conical section 53, and the lower end of the second side ear 14 abuts against the end of the conical section 53 to prevent the connecting rod 13 from retreating. If the connector 1 and the buckle 5 are to be disassembled, the connecting rod 13 needs to be pressed inwardly so that the lower end of the second side ear 14 is separated from the end of the conical section 53, and the connector 1 is disassembled, which has the advantage of simple disassembly.

[0025] The lower end of the cylindrical first plate body 11 is bent to form a first side ear 12, and the lower part of the first side ear 12 is sleeved with a first hoop 2. Since the connector 1 is formed by stamping and bending a plate, the first hoop 2 is sleeved on the cylindrical first plate body 11 to avoid the problem of the cylindrical first plate body 11 breaking.

[0026] The lower end of the cylindrical second plate 52 is bent to be provided with a third side ear 51, and the lower part of the third side ear 51 is sleeved with a second hoop 4. Similarly, the function of the second hoop 4 is the same as that of the first hoop 2, which prevents the cylindrical second plate 52 from breaking.

[0027] Furthermore, when the connector 1 is produced, the plate material is punched in advance to obtain the required contour and the structure of the first side ear 12 and the second side ear 14, and then the bending process is performed to bend the first side ear 12 and the second side ear 14 by 90 degrees, and finally the whole is bent to form a cylindrical structure. Similarly, the production process of the sleeve fastener 5 is consistent with that of the first connector 1.

[0028] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
