Description

Technical Field

[0001] The utility model relates to the technical field of sun visor vanity mirrors, in particular to a vanity mirror lamp circuit control structure. Background Art

[0002] The car sun visor is an indispensable component in a car. At present, the car sun visor on the market has a rotating shaft at one end, and the end of the rotating shaft away from the car sun visor is rotatingly connected to the inner top of the car frame. The other end of the car sun visor is fixed with a clamping shaft, and the clamping shaft is engaged and rotatably connected with the sun visor hook installed on the inner top of the car frame. When the car sun visor needs to block the sunlight on the front, the car sun visor can be rotated downward. When the car sun visor needs to block the sunlight from the side of the car, the clamping shaft can be separated from the sun visor hook, and the car sun visor can be rotated horizontally to enable the car sun visor to block the sunlight from the side of the car.

[0003] The car sun visor currently on the market includes a main body frame, a mirror glass installed on the main body frame and a lamp body. A light-transmitting area is arranged on the mirror glass, and the light-transmitting area and the lamp body are arranged in a front-to-back correspondence. When the lamp body is illuminated, the light emitted by the lamp body can pass through the light-transmitting area, thereby illuminating the mirror glass and the interior environment of the vehicle. A control circuit board connected to the lamp body is also installed in the main body frame.

[0004] There are currently two ways to control the conduction between the circuit board and the lamp body:

[0005] 1. It is realized by the angle control switch. The rotating shaft is rotated, and contacts are arranged opposite to each other in the rotating shaft. A guide column is fixed in the main body frame. Contacts are also arranged on both sides of the end of the guide column located in the rotating shaft. When the contact of the rotating shaft contacts the contact of the guide column, conduction is achieved. The contact size is small, and the sun visor needs to be at a corresponding angle to achieve conduction, which brings inconvenience to use. In addition, in actual use, when the car is bumpy or the connection between the rotating shaft and the top of the car frame fails, it will cause the contact to break, which will cause the lamp body to flash, affecting use;

[0006] 2. It is realized by a travel control switch, that is, the sliding cover covering the mirror glass moves into place to push the spring of the travel switch to press and connect the contact. However, after use, people often forget to reset the sliding cover, which causes the lamp body to be in a constant light state, resulting in a waste of electricity and even damage to the battery, which brings great inconvenience to use. Summary of the invention

[0007] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by this patent application is how to provide a makeup mirror lamp circuit control structure that can achieve two-level control, expand the angle adjustment range, improve lighting stability, and has a reliable structure.

[0008] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0009] A makeup mirror lamp circuit control structure, comprising a body frame, a rotating shaft and a control circuit board, wherein the control circuit board is fixedly mounted on the body frame, and is characterized in that it also comprises an angle control switch and a travel control switch which are electrically connected;

[0010] The angle control switch comprises two body conductive copper sheets fixedly installed in the body frame and arranged at intervals, an insulating head is fixed at the end of the rotating shaft, and the rotating shaft conductive copper sheets are fixed on both sides of the insulating head, the insulating head is located between the two body conductive copper sheets, the rotating shaft is provided with a wire passing channel, and the two rotating shaft conductive copper sheets are respectively connected to the outside with a positive wire and a negative wire;

[0011] The travel control switch is fixedly installed in the body frame, the two body conductive copper sheets are electrically connected to the positive pole and the negative pole of the travel control switch respectively, and the travel control switch is electrically connected to the control circuit board.

[0012] In this way, two-level control is realized by the angle control switch and the stroke control switch electrically connected to the control circuit board. Only when the angle control switch and the stroke control switch are in the on state at the same time, the lamp body will emit light. In actual use, when the lamp body needs to emit light, the sun visor is rotated to a certain angle, the conductive copper sheet of the rotating shaft is in contact with the conductive copper sheet of the main body, the sliding cover is pushed open, the sliding cover is pushed into place, the spring piece of the stroke control switch is pressed to be in contact with the contact point, and the lamp body emits light. By setting the conductive copper sheet of the rotating shaft and the conductive copper sheet of the main body, the contact area can be expanded compared with the existing contact method of the rotating shaft contact, thereby increasing the rotation angle range of the sun visor, and better avoiding the occurrence of the flashing of the lamp body. When the use is completed, the sun visor is rotated and reset, even if the sliding cover is not reset, the conductive copper sheet of the rotating shaft is disconnected from the conductive copper sheet of the main body, and the insulating head at the end of the rotating shaft is in contact with the conductive copper sheet of the main body, so that the circuit is disconnected, the lamp body is turned off, and the waste of electric energy is avoided, and the battery is better protected.

[0013] Among them, two bayonet holes are arranged in the main body frame, and the main body conductive copper sheet is engaged with the bayonet holes.

[0014] Wherein, the two sides of the conductive copper sheet of the rotating shaft are bent to form a card edge, and the insulating head is provided with a card groove that is engaged with the card edge directly facing the card edge.

[0015] Wherein, the connection between the rotating shaft and the insulating head and the conductive copper sheet of the rotating shaft is integrally formed by injection molding.

[0016] Wherein, a receiving groove is arranged in the main body frame, and the travel control switch is fixedly installed in the receiving groove of the main body frame.

[0017] In summary, the circuit control structure of the vanity mirror lamp has the advantages of being able to realize secondary control, expanding the angle adjustment range, improving the lighting stability, and having a reliable structure. The specific beneficial effects are as follows:

[0018] 1. Realize the secondary control requirements of the vanity mirror lamp;

[0019] 2. The conductive copper sheet of the shaft is integrally injection molded with the shaft, and the product is reliable;
