The means to achieve lightweight structure of new energy vehicles include structural optimization design, new high-strength and lightweight materials, and new lightweight manufacturing processes.

[0005] However, the existing structure for connecting the automobile buckle to the buckle base is usually composed of two circular positioning plates and a mounting column. The circular positioning plates easily cause the buckle to deviate at a large angle, which makes the buckle easily change its angle during insertion and changes the insertion guide direction, resulting in inconvenience in insertion. Summary of the invention

[0006] The embodiment of the present application provides an automobile clip to solve the problem in the related art that the existing automobile clip is easy to rotate during installation, causing the installation angle to shift, resulting in inconvenience in installation.

[0007] The embodiment of the present application provides a car buckle, including:

[0008] A buckle body, the buckle body comprising a positioning rib and elastic sheets arranged on both sides of the positioning rib;

[0009] A connecting body, the connecting body is used to connect the buckle body to the vehicle body, the connecting body comprises a mounting column and a first positioning plate and a second positioning plate respectively arranged at two ends of the mounting column, the first positioning plate is rectangular, and the second positioning plate is circular;

[0010] The mounting column is a hollow structure, a guide hole is opened on the side wall of the mounting column, a fixing plate for strengthening the friction between the mounting column and the buckle base is arranged in the guide hole, and a driving mechanism for driving the fixing plate is arranged in the mounting column.

[0011] In some embodiments, the driving mechanism includes a rotating rod disposed in the mounting column and a sleeve sleeved on the outside of the rotating rod;

[0012] A connecting rod is hinged between the sleeve and the fixing plate.

[0013] In some embodiments, the sleeve is threadedly connected to the rotating rod;

[0014] One end of the rotating rod passes through the mounting column and the first positioning plate in sequence and extends out, and the other end of the rotating rod is rotatably connected to the bottom of the mounting column.

[0016] In some embodiments, one end of the elastic sheet is connected to the positioning rib, and the other end is connected to the second positioning plate;

[0017] The elastic sheet and the positioning rib are spaced apart to form a cavity.

[0018] In some embodiments, the elastic sheet includes a clamping body and a limiting body connected to each other;

[0019] One end of the clamping body is connected to the positioning rib, and the other end is connected to the limiting body;

[0020] One end of the limiting body away from the clamping body is connected to the second positioning plate;

[0021] The clamping body is inclined, and one end of the clamping body connected to the limiting body is inclined in a direction away from the positioning rib;

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0040] The embodiment of the present application provides an automobile clip, which can solve the problem that the automobile clip is easy to rotate during installation, causing the installation angle to shift, resulting in inconvenience in installation.

[0041] See also Figure 1-5 As shown, the embodiment of the present application provides a car buckle, including:

[0042] The buckle body includes a positioning rib 6 and an elastic sheet 1 arranged on both sides of the positioning rib 6. The elastic sheet 1 allows the buckle to shrink when inserted into the hole to reduce the insertion force for easy insertion, and to recover after passing through the hole to increase the extraction force.

[0043] Connecting body, connecting body, connecting body is used to connect the buckle body to the sheet metal hole of the body sheet metal, the connecting body includes a mounting column 3 and a first positioning plate 41 and a second positioning plate 42 respectively arranged at both ends of the mounting column 3, the first positioning plate 41 is rectangular, the second positioning plate 42 is circular, the mounting column 3 is a hollow structure, a guide hole 33 is opened on the side wall of the mounting column 3, a fixing plate 35 for strengthening the friction between the mounting column 3 and the buckle base is arranged in the guide hole 33, and a driving mechanism for driving the fixing plate 35 is arranged in the mounting column 3.

[0044] When the buckle slides into the mounting hole in the buckle base, the first positioning plate 41 and the second positioning plate 42 are respectively located on the upper and lower sides of the hole, so that the buckle can be snapped and fixed on the buckle base. At this time, the mounting column 3 is located in the hole. After adjusting the mounting angle of the buckle so that the elastic sheet 1 and the positioning rib 6 are inserted into the sheet metal hole of the sheet metal at a suitable angle, the fixing plate 35 is driven by the driving mechanism to move toward the inner wall of the hole until it is tightly pressed against the inner wall of the mounting hole of the buckle base. This can fix the angle of the buckle and prevent it from rotating, thereby avoiding angle deviation when the buckle is inserted, which will cause changes in the installation force and inconvenience in installation.

[0045] Among them, the first positioning plate 41 is a rectangle and is arranged in the buckle base. Through the rectangular structure, the first positioning plate 41 can avoid excessive rotation angle, which will cause the buckle to be offset too much. The second positioning plate 42 is circular to avoid the area of ​​the foam pad 5 matched with it being too small, resulting in poor sound insulation and shock absorption effect.

[0046] In some optional embodiments, see Figure 1 and Figure 3-4 As shown, in the automobile buckle, the driving mechanism includes a rotating rod 31 arranged in the mounting column 3 and a sleeve 32 sleeved on the outside of the rotating rod 31, and a connecting rod 34 is hinged between the sleeve 32 and the fixing plate 35.

[0047] In this embodiment, the sleeve 32 is threadedly connected to the rotating rod 31 , one end of the rotating rod 31 passes through the mounting column 3 and the first positioning plate 41 in sequence and extends out, and the other end of the rotating rod 31 is rotatably connected to the bottom of the mounting column 3 .

[0048] After the buckle is connected to the buckle base and the insertion angle of the buckle is adjusted, a tool that can be inserted into the buckle base, such as a clamp or a wrench, is clamped on the protruding end of the rotating rod 31, and then the rotating rod 31 is rotated to drive the sleeve 32 to rotate, and then the sleeve 32 descends, and the sleeve 32 pushes the connecting rod 34, so that the connecting rod 34 pushes the fixing plate 35 to move toward the inner wall of the hole of the buckle base until the fixing plate 35 is pressed against the inner wall of the hole, so that the buckle cannot rotate.

[0049] In some optional embodiments, see Figure 1 and Figure 3 As shown, in the automobile buckle, two limit plates 36 are arranged on the rotating rod 31 at intervals, and the sleeve 32 is arranged between the two limit plates 36. The limit plates 36 limit the distance of the sleeve 32 moving up and down to prevent the sleeve 32 from moving too long when moving, so that the fixing plate 35 is not pushed out of the guide hole 33, or the fixing plate 35 falls into the inside of the mounting column 3. The fixing plate 35 is embedded in the guide hole 33 to prevent the fixing plate 35 from falling out of the guide hole 33 when the displacement is too large, so that it cannot be restored. In addition, the spacing between the holes of the mounting column 3 and the buckle base is small, which will also limit the fixing plate 35 from falling into the gap between the buckle base and the mounting column 3.

[0050] In some optional embodiments, see Figure 2 and Figure 5 As shown, in the automobile buckle, one end of the elastic sheet 1 is connected to the positioning rib 6, and the other end is connected to the second positioning plate 42. The elastic sheet 1 and the positioning rib 6 are spaced apart to form a cavity 13. The setting of the cavity 13 can increase the elastic deformation of the elastic sheet 1 and improve the insertion and extraction force of the elastic sheet 1.

[0051] In some optional embodiments, see Figure 1 As shown, in the automobile buckle, the elastic sheet 1 includes a clamping body 11 and a limiting body 12 connected to each other;

[0052] One end of the clamping body 11 is connected to the positioning rib 6, and the other end is connected to the limiting body 12. The end of the limiting body 12 away from the clamping body 11 is connected to the second positioning plate 42. The clamping body 11 is inclined, and the end of the clamping body 11 connected to the limiting body 12 is inclined in a direction away from the positioning rib 6. The limiting body 12 and the second positioning plate 42 are vertically connected to each other.

[0053] The inclined setting of the snap-on body 11 increases the distance of its elastic deformation, reduces the insertion force and improves the extraction force. Since the diameter of the hole in which the buckle in this embodiment is assembled is 6.5 mm, the limit body 12 and the second positioning plate 42 are vertically connected to avoid the inclined setting causing an increase in the insertion and extraction force, which would make it inconvenient to use in a 6.5 mm hole.

[0054] In this embodiment, a limiting cavity 121 is formed between the limiting body 12 and the second positioning plate 42. When the buckle can be restored after the elastic sheet 1 is inserted into the hole, the limiting cavity 121 can then abut and be clamped on the sheet metal hole, thereby increasing the extraction force.

[0055] In this embodiment, the spacing between the ends of the snap-fit ​​body 11 away from the positioning rib 6 is preferably 7.3 mm-7.7 mm, the length of the snap-fit ​​body is preferably 9.1 mm-9.5 mm, and the width of the snap-fit ​​body is preferably 6.3 mm.

[0056] In some optional embodiments, see Figure 2 and Figure 5 As shown, the car buckle also includes

[0057] The foam pad 5 is sleeved on the outside of the buckle body and is located on the second positioning plate 42. The foam pad 5 can be used to insulate and reduce vibration of the friction between the buckle base and the sheet metal after the buckle is installed.

[0058] Working principle and process of this application:

[0059] The locking plate 35 is then pushed back into position to lock the locking cam 35 in the locking cam 36. The locking plate 35 is then pushed back into position to lock the locking cam 36. The locking plate 35 is then pushed back into position to lock the locking cam 36.

[0060] When the buckle is inserted into the hole of the sheet metal, the elastic sheet 1 is compressed. After being inserted into the hole, the elastic sheet 1 recovers after being inserted into the hole, and then the limiting cavity 121 abuts against and is clamped on the sheet metal hole.
