Description

Technical Field

[0001] The utility model relates to the technical field of vehicle body assembly, in particular to a positioning component, a hinge connecting piece and an automobile. Background Art

[0002] In the process of vehicle body manufacturing, positioning pins are usually used for positioning connection. The traditional magnetic positioning pin is of an integral structure, usually with brass as the base body. The top of the positioning pin is a step, and a cylindrical magnet is embedded in the inner cavity below the step of the positioning pin with clay. The cylindrical magnet is sealed in the inner cavity of the positioning pin, and a plurality of magnetic leakage holes are arranged on the inner cavity around the cylindrical magnet for adsorption. Since the magnet cannot be in close contact with the adsorbed object, the magnetic adsorption force is weak, which will affect the positioning accuracy during use, cause hole position deviation, and affect the product quality. Moreover, because the traditional magnetic positioning pin and the magnet are of an integral design, after the positioning pin is deformed, worn or the magnetic force of the magnet is reduced, the whole set can only be discarded, resulting in cost waste.

[0028] In order to illustrate the technical solution of the present utility model, the following will be described through specific embodiments.

[0029] As Figure 1 shown, a positioning component of an embodiment of the present utility model includes a positioning bolt 31, a pin sleeve 2 and a magnet 21. A receiving cavity for receiving the positioning bolt 31 is provided in the pin sleeve 2. The receiving cavity is a semi-closed structure with one end open, and the magnet 21 is provided at the end of the receiving cavity away from the opening. The positioning bolt 31 is magnetically connected to the pin sleeve 2.

[0030] It should be noted here that the positioning bolt 31 and the pin sleeve 2 can also be connected by threads or snapped together.

[0031] In this embodiment, the positioning bolt 31 is arranged in the accommodating cavity and magnetically connected to the pin sleeve 2 to form a positioning pin structure to achieve the positioning function. After the pin sleeve 2 is separated from the positioning bolt 31, it can also be used as a bolt to fix an object. When the magnetic force of the magnet 21 in the pin sleeve 2 of the positioning assembly of the present utility model is reduced, the pin sleeve 2 can be separated from the positioning bolt 31, which is convenient for replacing the magnet 21.

[0032] As Figure 1 shown, in some embodiments of the present utility model, the positioning bolt 31 has a clearance fit with the pin sleeve 2 and the magnet 21 respectively. Through the clearance fit between the positioning bolt 31, the pin sleeve 2 and the magnet 21, it is convenient for the magnet 21 to adsorb the positioning bolt 31, so that when the pin sleeve 2 is sleeved on the positioning bolt 31, it can be prevented from detaching from the hinge 3.

[0033] In some embodiments of the present utility model, the clearance between the positioning bolt 31 and the pin sleeve 2 is 0 - 0.1 mm. And / or, the clearance between the positioning bolt 31 and the magnet 21 is 0.5 - 1.5 mm. By controlling the above clearance range, it is ensured that the pin sleeve 2 is firmly adsorbed on the positioning bolt 31.

[0034] As Figure 1 shown, in some embodiments of the present utility model, a guiding portion 22 is provided at one end of the pin sleeve 2 away from the opening, and the outer diameter of the guiding portion 22 gradually decreases in the direction away from the opening of the pin sleeve 2, which is convenient for the pin sleeve 2 to be inserted into the mounting hole 11.

[0035] In some embodiments of the present utility model, the included angle between the guiding portion 22 and the outer wall of the pin sleeve 2 is 165° - 175°.

[0036] On the other hand, the present utility model also provides a hinge connecting member 3 for connecting with a vehicle body. The hinge connecting member 3 includes a hinge fixed page 32 and a hinge movable page 33. The hinge fixed page 32 is rotatably connected to the hinge movable page 33. A locking bolt and the positioning assembly as described in any one of the above are provided on the hinge fixed page 32. Specifically, the locking bolt has the same structure and model as the positioning bolt 31.

[0037] In this embodiment, by providing a positioning assembly on the hinge connecting member 3 and then connecting it to the vehicle body, the positioning of the hinge connecting member 3 is simple, the operation is convenient, no auxiliary tooling is required, the labor intensity is low, and the production efficiency is improved.

[0038] In some embodiments of the present utility model, the vehicle body includes a tailgate (not shown in the figure) and an outer roof panel 1. A plurality of mounting holes 11 are provided on the outer roof panel 1, and the locking bolts are arranged opposite to the mounting holes 11. The pin sleeve 2 is in clearance fit with the mounting hole 11.

[0039] In this embodiment, the tailgate with the hinge 3 is directly positioned on the outer roof panel 1, reducing the dimensional chain and effectively ensuring the accuracy of the gap and surface difference around the tailgate. By detachably sleeving the pin sleeve 2 on the outer periphery of the positioning bolt 31, it is convenient to remove the pin sleeve 2 after the tailgate is positioned and installed. Moreover, the pin sleeve 2 can be reused, avoiding increasing the procurement cost of the hinge 3 and further increasing the weight of the hinge 3. The clearance fit between the pin sleeve 2 and the mounting hole 11 facilitates adjusting the gap and surface difference around the tailgate, enabling the repair and adjustment of the tailgate assembly with poor assembly accuracy without replacement.

[0040] In some embodiments of the present utility model, the clearance between the pin sleeve 2 and the mounting hole 11 is 0 to 0.1 mm. On the one hand, it is convenient for the pin sleeve 2 to disengage from the mounting hole 11. On the other hand, it is convenient for the positioning bolt 31 to be adjusted within the mounting hole 11 to adjust the gap and surface difference around the tailgate, enabling the repair and adjustment of the tailgate with poor assembly accuracy without replacement.

[0041] As Figure 3 shown, in some embodiments of the present utility model, the positioning assembly is arranged on the side of the hinge fixed page close to the outer edge of the tailgate, facilitating subsequent adjustment of the gap and surface difference around the tailgate.

[0042] In this embodiment, the positioning method of the hinge connecting member 3 installed on the vehicle body is as follows:

[0043] Sleeve the pin sleeve 2 on the outermost positioning bolt 31 of the hinge 3 of the tailgate. Align the pin sleeve 2 on the hinge 3 with the outermost mounting hole 11 on the outer part of the roof. Lock the positioning bolt 31 on the hinge 3 that is not sleeved with the pin sleeve 2. Remove the pin sleeve 2, adjust the position of the outermost positioning bolt 31 on the hinge 3 at the mounting hole 11, and lock the outermost positioning bolt 31 on the hinge 3.

[0044] On the other hand, a vehicle according to an embodiment of the present utility model includes the hinge connecting member 3 described in any one of the above embodiments.

[0045] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features.
