Detailed Description

In order to make the utility model realize, the technical means, the creation characteristics, the achievement purpose and the efficacy are easy to understand and understand, the utility model is further explained by combining the specific implementation mode.

As shown in fig. 1 to 3, the utility model comprises a rotation part 1, a fixed part 2 and a movable part 3, wherein the top of the rotation part 1 is a ball socket 11, a ball socket shell 14 of the ball socket 11 is fixedly connected with a fixed part shell 13 of the fixed part 2, and the movable part 3 is slidably connected in the fixed part 2 and extends out of the front end;

the front end of the ball socket shell 14 is fixedly connected with a ball socket shell extension part 15, the ball socket shell extension part 15 extends into the fixing part shell 13 and is connected with the fixing part shell in a sliding mode, a clamping block 16 is further fixedly connected to the outer surface of the ball socket shell extension part 15, and a corresponding clamping block groove is formed in the inner wall of the fixing part shell 13.

The fixture block 13 is plugged into the fixture block groove through interference fit to limit the position, and the mechanical strength of the connecting part is improved. The laser welding has low connecting strength due to small connecting surface, and the structure of the fixture block 13 and the fixture block groove can well supplement the connecting strength.

A welding portion 17 is provided between the ball housing 14 and the fixing portion housing 13, and the ball housing 14 and the fixing portion housing 13 are fixedly connected by welding. Besides improving the sealing performance, the laser welding also avoids the shaking in the working process and improves the connection stability.

The fixed part 2 is also fixedly connected with a motor 12. The difference in thickness between the ball housing 14 and the ball housing extension 15 is the same as the thickness of the stationary portion housing 13. After the fixture block 13 is plugged into the fixture block groove, the relative position of the fixing part shell 13 and the ball socket shell 14 is determined, the thickness of the fixing part shell 13 is the same as the thickness difference between the ball socket shell 14 and the ball socket shell extension part 15, and the outer parts of the fixing part shell 13 and the ball socket shell extension part are flush with each other and have high integrity.

The specific implementation mode and principle are as follows:

ball socket 11 in the outside adopts nylon to add glass fiber material, links to each other with the bulb of automobile body side, and fixed part casing 13 adopts nylon to add glass fiber material, provides the structure space for other work pieces. The internal workpiece comprises a motor 12, a motor connecting bush, a bearing, a screw rod, a spring inner sleeve, a screw rod sleeve and the like, and forms a main body structure of the electric stay bar.

After installing the major structure, need be with fixed part casing 13 and ball socket 11's ball socket casing 14 fixed connection, the laser welding technology of this scheme adoption at first needs stretch into fixed part casing 13 with ball socket casing extension 15 of ball socket casing 14 in, stretches into the in-process, makes the fixture block 16 on the ball socket casing extension 15 stopper in the fixture block groove on the ball socket casing 14 inside wall through interference fit's mode.

After the fixture block 13 is plugged into the fixture block groove, the relative position of the fixing part shell 13 and the ball socket shell 14 is determined, then the gap between the fixing part shell 13 and the ball socket shell 14 is subjected to laser welding treatment, and a welding part 17 formed after welding is polished and polished, so that the outer part is flush and smooth, and the integrity and the aesthetic degree are higher.

Based on the foregoing, the utility model discloses a laser welding has replaced the fixed mode of other parts such as original jump ring, has both reduced the assembly part, has also reduced process flow, has reduced assembly cost, and more importantly has alleviateed the weight of product. Meanwhile, the clamping block is plugged into the clamping block groove through interference fit to limit, and the mechanical strength of the connecting part is improved. And the welding part that connects adopts laser welding's mode fixed, has also thoroughly sealed the joint gap simultaneously, ensures the leakproofness.

It will be appreciated by those skilled in the art that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The embodiments disclosed above are therefore to be considered in all respects as illustrative and not restrictive. All changes within the scope of the invention or within the scope equivalent to the invention are all embraced by the invention.
