Technical Field

[0001] The utility model relates to the technical field of automobile lamp structures, in particular to a self-limiting stroke structure of an internal adjustment slider of an automobile lamp. Background Art

[0002] The headlight installed on the front of the car cannot guarantee that its light can shine on the road surface required by the design due to the deviation of its body mounting structure. This requires the lighting system (reflector) in the headlight to be adjusted so that its light can shine on the road surface required by the design. When adjusting the lighting system (reflector), since the debugging personnel do not understand the internal structure of the lamp, when rotating the adjustment screw forward or backward, the ball head slider of the hanging lighting system (reflector) is easily disengaged or the slide groove is disengaged from the ball socket on the ball head due to the unlimited travel function of the slider, making the lamp unable to work normally. Therefore, it is necessary to design a structure to limit the moving stroke of the ball head slider to solve the above technical problems. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides a self-limiting stroke structure of an internal adjustment slider of a vehicle lamp, which is used to solve the problem that the slider in the traditional lighting system cannot be adjusted within a limited stroke, resulting in easy falling off and failure to work normally.

However, it should be understood that these physical details should not be used to limit the utility model. In other words, in some embodiments of the utility model, these physical details are not necessary. In addition, for the purpose of simplifying the diagram, some conventional structures and components will be depicted in a simple schematic manner in the diagram.

[0020] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components are required to be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0021] In the description of this technology, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this technology can be understood according to specific circumstances.

[0022] In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0023] See also Figure 1-4 The utility model discloses a self-limiting stroke structure of an internal adjustment slider of a vehicle lamp, comprising a sliding structure, an adjusting screw 1 and a connecting portion, characterized in that the sliding structure comprises a slider 6, a limiting sleeve 7 is integrally formed on the upper surface of the slider 6, and the two ends of the limiting sleeve 7 are respectively fixedly connected with a first internally threaded tube 8 and a second internally threaded tube 12, the screw rod portion of the adjusting screw 1 is threadedly connected with the first internally threaded tube 8, the outer wall of the first internally threaded tube 8 is fixedly connected with the first limiting structure, the inner wall of the limiting sleeve 7 and one side close to the second internally threaded tube 12 is fixedly connected with the second limiting structure, and the connecting portion is installed in the second internally threaded tube 12.

[0024] The first limiting structure includes two protective plates 9 and a first spring 11. The two protective plates 9 are symmetrically fixedly connected to the two sides of the outer wall of the first internally threaded tube 8. The first spring 11 is fixedly connected between the two protective plates 9 and away from the side of the first internally threaded tube 8. The adjusting screw 1 passes through the middle of the first spring 11 and is threadedly connected to the first internally threaded tube 8. A flange end 5 is fixedly connected to the adjusting screw 1 near the middle, and the flange end 5 is located on the right side of the first spring 11. A process groove 4 is opened on the surface of the adjusting screw 1 and near the left side of the flange end 5.

[0025] The second limiting structure comprises a second spring 13 , one end of the second spring 13 is fixedly connected to the right side of the inner wall of the limiting sleeve 7 , and the other end of the second spring 13 is fixedly connected to a push block 14 .

[0026] The connecting portion includes a ball head 15 , one end of which is fixedly connected to a screw rod 16 , and the screw rod 16 is threadedly connected to the second internally threaded tube 12 .

[0027] It should be noted that the sliding structure is slidably connected inside the lamp housing, the left end of the adjusting screw 1 is fixed to the outside of the lamp housing through a sealing gasket 2 and a locking gasket 3, and the connecting part is connected to the lamp.

[0028] When adjusting the position of the sliding structure, the ball head 15 and the slider 6 move to the left when the adjusting screw 1 is rotated clockwise, and the light is adjusted by the ball head 15. When the slider 6 moves to the left for a distance, the adjusting screw 1 hits the gasket and compresses the spring. At this time, the adjusting screw 1 is just de-threaded from the first internally threaded tube 8, and the slider 6 can no longer move to the left. Under the action of the elastic force of the second spring 13, the push block 14 always applies a thrust to the adjusting screw 1, so that the threaded end of the adjusting screw 1 is just engaged with the first internally threaded tube 8, which can ensure that the adjusting screw 1 can be threadedly connected with the first internally threaded tube 8 when it is rotated counterclockwise next time, which is convenient for callback.

[0029] When the adjusting screw 1 is rotated counterclockwise, the ball head 15 and the slider 6 move to the right, and the light is adjusted by the ball head 15. When the slider 6 moves to the right for a certain distance, the first spring 11 touches the flange end 5, and the flange end 5 squeezes the first spring 11. At this time, the adjusting screw 1 is just dethreaded from the first internally threaded tube 8, so that the slider 6 can no longer move to the right. The first spring 11 continues to apply thrust to the flange end 5, so that the threaded end of the adjusting screw 1 is just engaged with the first internally threaded tube 8, which can ensure that the adjusting screw 1 can be threadedly connected with the first internally threaded tube 8 during the next clockwise rotation, which is convenient for callback.

[0030] Through the above technical solution, the adjustment screw 1 is used in conjunction with the first internal threaded tube 8 to limit the stroke of the sliding structure, thereby preventing the sliding structure from excessively moving and causing damage to the lamp. In addition, by providing the first spring 11 and the second spring 13, the adjustment screw 1 can still engage with the end of the first internal threaded tube 8 after being stripped, which is convenient for making an adjustment again, and is very convenient to use.

[0031] In some other embodiments, a positioning structure is provided between the two protective plates 9 and near the left side of the first spring 11. The positioning structure includes two arc plates 10. The two arc plates 10 are respectively fixedly connected to the opposite sides of the two protective plates 9 and are mirror images of each other. The adjusting screw 1 passes through the center of the positioning structure.

[0032] Through the above technical solution, a limiting and protective effect is achieved during the installation and movement of the adjusting screw 1, making it convenient for workers to install the adjusting screw 1.

[0033] The above description is only an embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent substitution, improvement, etc. made within the spirit and principle of the present invention shall be included in the scope of the claims of the present invention.
