Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, and more specifically to a headlight adjustment connector. Background Art

[0002] At present, all automobile lights are equipped with a light adjustment device for adjusting the illumination direction of the light. Generally speaking, the adjustment of the headlights is achieved based on the adjustment of the tilt angle of the lamp bowl. For example, the guide structure of a headlight adjustment mechanism disclosed in publication number CN203222064U realizes the change of length by rotating the adjustment screw, thereby pushing the headlight forward or pulling the headlight backward to achieve the change of the illumination angle of the light. However, it was found during use that after the existing structure is adjusted, especially after the headlight is tilted, the connecting part will tilt synchronously, resulting in errors in the fit between the screw and the connecting part. After a long time, the rotation is prone to jamming and the adjustment is not smooth. Therefore, this application is proposed to solve the deficiencies in the prior art. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a headlight adjustment connector, which ensures long-term smooth rotation and adjustment through the cooperation of a bracket, a ball head component and a threaded rod, as well as the structural design within the bracket and the ball head component.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a headlight adjustment connecting piece, comprising a bracket and a ball head component, the bracket is fixedly connected to the headlight bowl, a threaded rod is passed through the ball head component, a connecting cavity is provided in the bracket, the ball head component is movably fitted in the connecting cavity, and arc structures for constraining the ball head component are provided at both ends of the connecting cavity; a straight groove is provided on the inner wall of the connecting cavity, a pin is provided on the ball head component, the pin extends into the straight groove, and a gap is provided between the pin and the side wall and bottom of the straight groove, a threaded hole is provided in the ball head component for threadedly fitting with the threaded rod, and an inclined guide piece is provided on the side of the threaded hole facing outside the bracket.

[0005] The utility model is further configured as follows: the bracket includes a first connecting portion and a second connecting portion, the first connecting portion is provided with a snap-fit structure for matching with the headlight bowl, and the connecting cavity is arranged in the second connecting portion.

[0006] The utility model is further configured as follows: a plurality of grooves arranged along the axial direction are arranged in the threaded hole.

[0007] The utility model is further configured as follows: four grooves are provided, and the four grooves are annularly symmetrically arranged.

[0008] The utility model is further configured as follows: the gap is set between 1-1.5 mm.

[0009] The utility model is further configured such that: an inclined guiding portion is provided on the arc-shaped structure at the outer end of the connecting cavity.

[0010] To sum up, the utility model has the following beneficial effects:

[0011] An inclined guiding piece is arranged on the ball head component of the utility model. After the screw rod is rotated and adjusted, the bracket and the ball head component will be pushed forward or pulled backward. At this time, the bracket will rotate and tilt relative to the ball head component. The inclined guiding piece can block the edge of the bracket to prevent the bracket from tilting and getting stuck on the threaded rod, which affects its rotation adjustment. At the same time, the utility model is also provided with an inclined guiding portion, and its inclined surface structure is used to avoid the threaded rod when a lateral offset occurs.

[0012] The utility model also prevents the threaded rod from driving the ball head component to rotate by arranging a pin column and a linear groove. At the same time, the setting of the gap realizes fault tolerance during the offset process to ensure the flexibility of the bracket and the ball head component. In addition, a groove is arranged in the threaded hole of the ball head component, so that the threaded hole can be slightly deformed within a small range to better fit the threaded rod and ensure the smooth rotation of the screw rod.

Detailed Description of the Embodiment

[0019] The following further describes the present utility model in detail with reference to the drawings.

[0020] This embodiment discloses a headlight adjustment connecting member, as Figures 1-5As shown in the figure, it includes a bracket 1 and a ball head component 2. The bracket 1 is fixedly connected to the headlight bowl, and a threaded rod is passed through the ball head component 2. Among them, a light source is provided in the middle of the headlight bowl, and the adjustment of the bowl can achieve the adjustment of the irradiation direction of the headlight; the threaded rod is rotatably arranged on the headlight housing. When the threaded rod rotates, the ball head component 2 and the bracket 1 are driven by the threaded rod to move on the threaded rod, thereby driving the end of the bowl connected to the bracket to move back and forth. The other end of the bowl is hinged, so the inclination adjustment of the bowl can be achieved by moving back and forth.

[0021] Furthermore, a connecting cavity 3 is provided in the bracket 1 of this embodiment. The ball head component 2 is movably fitted in the connecting cavity 3, and arc-shaped structures for restricting the ball head component 2 are provided at both ends of the connecting cavity 3; the ball head component 2 is prevented from coming out of the connecting cavity 3 through the arc-shaped structure, and the arc is adapted to the spherical surface without affecting the rotation of the ball head component 2. A straight groove 4 is provided on the inner wall of the connecting cavity 3, and a pin 5 is provided on the ball head component 2. The pin 5 extends into the straight groove 4. The straight groove 4 is arranged along the axial direction of the threaded rod 10. Therefore, through the cooperation of the pin 5 and the straight groove 4, when the threaded rod 10 rotates, the ball head component 2 will not rotate with the threaded rod, but will move along the axial direction of the threaded rod 10. And a gap 6 is provided between the side wall and the bottom of the straight groove 4 and the pin 5. Through the setting of the gap 6, the tolerance of the ball head component 2 rotating in the connecting cavity is increased, ensuring the flexibility of the ball head component 2. A threaded hole 7 that is threadedly engaged with the threaded rod is provided in the ball head component 2. An inclined guide piece 8 is provided on the side of the threaded hole 7 facing outside the bracket 1. Through the setting of the inclined guide piece 8, when the bracket 1 is tilted during adjustment, the inclined guide piece 8 will block the housing of the bracket, specifically, it will block the outer edge of the connecting cavity, preventing it from getting stuck on the threaded rod 10, so as to ensure the smooth rotation of the threaded rod through the inclined guide piece 8.

[0022] Furthermore, the bracket 1 includes a first connecting portion 101 and a second connecting portion 102. A buckle structure 11 is provided on the first connecting portion 101 for forming a buckle fit connection with the headlight bowl, and the connecting cavity 3 is arranged in the second connecting portion 102. Among them, the buckle structure 11 can be the inclined plane structure in the drawing. During installation, it only needs to be snapped in along the inclined plane, which is very convenient. Of course, other existing buckle structures can also be used to fix the bowl.

[0023] Furthermore, a plurality of grooves 701 are provided in the threaded hole 7 along the axial direction. Through the arrangement of the grooves 701, the threaded hole 7 has a slight deformation. Although the ball head component 2 can rotate relative to the bracket 1, when the bracket 1 is tilted, it will inevitably affect the ball head component 2 and cause a small amount of tilt of the ball head component 2. At this time, the cooperation between the threaded hole 7 and the threaded rod 10 will be stuck. However, in this embodiment, the grooves 701 are provided, which enables the threaded hole 7 to deform slightly to a certain extent, so that the threaded hole 7 can better adapt to the threaded rod 10, thus avoiding the problem of the rotation of the threaded rod 10 being stuck.

[0024] Further preferably, four grooves 701 are provided, and the four grooves 701 are symmetrically arranged in a ring shape. The four grooves 701 can well adapt to the deformation in all directions, and the structure is also stable.

[0025] Furthermore, the clearance 6 in this embodiment is preferably set between 1 - 1.5 mm. On the one hand, this clearance does not allow the pin 5 to shake randomly in the linear groove 4, and on the other hand, it provides enough tolerance space to ensure that the ball head component 2 can move in the connecting cavity 3.

[0026] Furthermore, an inclined guiding portion 9 is provided on the arc-shaped structure at the outer end of the connecting cavity 3 in this embodiment. When this connecting piece is adjusted, it is basically tilted and adjusted along the up and down direction of the attachment Figure 2 However, as the service life prolongs, the fitting error becomes larger, and there will also be a small inclined movement in the left and right directions of the attachment Figure 2 At this time, due to the inclined structure, the inclined guiding portion 9 leaves enough space for the threaded rod 10. Even if a certain inclination occurs, the inclined guiding portion 9 will not catch the threaded rod 10, further ensuring the smooth rotation of the threaded rod 10.

[0027] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention shall be included in the protection scope of the present invention.
