Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile switches, in particular to an in-car reading light which can be adjusted at multiple angles. Background Art
[0002] Car interior reading lights are used for interior lighting and are often installed on the roof of the car or above the door. They are generally fixed structures and the illumination angle cannot be adjusted. In order to meet the stringent requirements of current customers, it is required that the reading lights can be easily adjusted in angle. The existing structure uses a cross pin for adjustment and sets a corresponding gear track, but the adjustment angle of this structure is limited and can only be adjusted to a specific angle according to the shape of the track. It cannot be infinitely adjusted, that is, it cannot stay at any angle. In addition, when the pin gear is coordinated, there will be a sudden change in the operating force, the operating feel is not good, and it is often accompanied by the sound of gear collision, which affects the customer's experience. Utility Model Content
[0003] The utility model aims to provide a car reading lamp which can be adjusted at multiple angles, so as to solve the problem that the existing reading lamp has a poor adjusting and rotating feel.
[0004] The technical solution adopted by the utility model to solve its technical problems is: a multi-angle adjustable in-vehicle reading light, comprising a shell, a bowl-shaped base is arranged at the bottom of the shell, a rotating seat is arranged on the bowl-shaped base, a rotating mounting part which rotates in cooperation with the bowl-shaped base is arranged at the bottom of the rotating seat, and a pressure block is arranged above the rotating mounting part to prevent the rotating seat from falling off, the pressure block is a bowl-shaped structure adapted to the inner wall of the rotating mounting part, and a connecting bolt is arranged between the pressure block and the bowl-shaped base; a rotating clearance hole is arranged at the bottom of the rotating mounting part, and elastic rubber rings for realizing a damping feel are arranged between the rotating mounting part and the bowl-shaped base, and between the rotating mounting part and the pressure block; a circuit board and a light-emitting component are arranged on the rotating seat, and an outer cover is also fixedly arranged.
[0005] In order to ensure that the outer cover does not generate friction with the shell when rotating, and at the same time, ensure the compactness of the structure and avoid leakage of the internal structure, a rotating shell is connected between the rotating seat and the outer cover. The rotating shell is spherical in shape, and the inner wall of the shell is spherical in shape to match the rotating shell.
[0006] In order to prevent the rotating seat from rotating around its own axis direction in the shell, a limiting arm is arranged on the rotating seat, and a limiting groove is arranged on the shell. The limiting arm extends into the limiting groove and is gap-matched with the limiting groove.
[0007] To facilitate assembly, the turning range of the rotating seat can be limited by the cooperation of the installation limit column and the rotation clearance hole. An installation limit column is arranged in the middle position of the bowl-shaped base, and an installation hole adapted to the installation limit column is arranged on the pressure block.
[0008] To improve the service life of the electrical components on the rotating seat, a set of weight-reducing and heat-dissipating holes is also provided on the rotating mounting part.
[0009] To prevent slipping when operating with fingers, a set of anti-slip patterns is also provided on the side edge of the outer cover.
[0010] Advantages of the present utility model: The rotating seat and the housing of the present utility model are matched with a bowl-shaped structure to achieve rotation, and can be flipped at any angle. At the same time, relying on the damping effect of the elastic rubber ring, the operating feel can be achieved. At the same time, it can also stop swinging at any angle, that is, it can stay at any flipping angle, realizing stepless adjustment of the irradiation angle of the reading lamp. The cooperation between the limiting arm and the limiting groove can effectively prevent the invalid rotation of the rotating seat, that is, the rotation will not change the irradiation angle of the reading lamp. The anti-slip patterns can also improve the operating feel.

[0017] Embodiment, as Figures 1 to 5 shown, a multi-angle adjustable in-vehicle reading lamp includes a housing 1, a rotating seat 2 rotatably installed in the housing 1. A circuit board 6 and a light-emitting component 7 are provided on the rotating seat 2, and an outer cover 8 covering the light-emitting component 7 is also fixedly provided. The light-emitting component 7 includes an LED light source 71, a lens 72, a light-emitting bowl 73 and a lamp shade 74 provided on the circuit board 6. This part is a prior art structure and will not be described in detail here. A rotating outer shell 9 is connected between the rotating seat 2 and the outer cover 8. The rotating outer shell 9 is spherical in shape, and the inner wall of the housing 1 is spherical in shape adapted to the rotating outer shell 9.
[0018] The innovation of this utility model lies in the cooperation between rotating components to achieve stepless adjustment of the irradiation angle and a good operating feel. The specific implementation structure is as follows: A bowl-shaped base 11 is provided at the bottom of the housing 1. A rotating mounting portion 21 that rotates in cooperation with the bowl-shaped base 11 is provided at the bottom of the rotating seat 2. A pressing block 3 is also provided above the rotating mounting portion 21 to prevent the rotating seat 2 from falling off. The pressing block 3 is a bowl-shaped structure adapted to the inner wall of the rotating mounting portion 21. The bowl-shaped base 11, the rotating mounting portion 21, and the pressing block 3 are designed concentrically. The pressing block 3 is fixed to the bowl-shaped base 11 by a connecting bolt 4. After assembly in place, a gap for the rotating mounting portion 21 to move is left between the pressing block 3 and the bowl-shaped base 11, enabling the rotating seat 2 to rotate.
[0019] The specific cooperation structure of the bowl-shaped base 11, the rotating mounting portion 21, and the pressing block 3 is as follows: An installation limit post 13 is provided at the middle position of the bowl-shaped base 11. An installation hole 31 adapted to the installation limit post 13 is provided on the pressing block 3. A rotating relief hole 22 is provided at the bottom of the rotating mounting portion 21, and the diameter of the rotating relief hole 22 is larger than that of the installation limit post 13. When the rotating seat 2 flips, the rotating relief hole 22 moves relative to the installation limit post 13. When the side wall of the rotating relief hole 22 abuts against the installation limit post 13, it cannot flip further. Therefore, this structure can also be used to control the flipping amplitude of the rotating seat 2.
[0020] To achieve an operating feel and stop at any flipping angle, elastic rubber rings 5 for achieving a damping feel are provided between the rotating mounting portion 21 and the bowl-shaped base 11, and between the rotating mounting portion 21 and the pressing block 3. Through the elastic rubber rings 5, an interference fit is achieved between the rotating mounting portion 21 and the bowl-shaped base 11 and the pressing block 3. When the rotating seat 2 is not stressed, clamping and positioning can be achieved. This structure has a good operating feel and no noise.
[0021] To avoid ineffective rotation of the rotating seat 2, a limiting arm 23 is provided on the rotating seat 2, and a limiting groove 12 is provided on the housing 1. The limiting arm 23 extends into the limiting groove 12 and has a clearance fit with the limiting groove 12. To facilitate operation by the operator and prevent slipping, a set of anti-slip patterns 81 is provided on the side edge of the outer cover 8.
[0022] To improve the heat dissipation capacity of the reading lamp and extend its service life, a set of weight-reducing and heat-dissipating holes 24 is also provided on the rotating mounting portion 21. The weight-reducing and heat-dissipating holes 24 can dissipate heat and, at the same time, play a role in weight reduction.
[0023] The above has made an exemplary description of the present utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the present utility model is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present utility model; or without improvement, the above concept and technical solution of the present utility model are directly applied to other occasions, all are within the protection scope of the present utility model.
