[0043] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings.

[0044] Combination Figure 1 and Figure 6 A rearview mirror for mounting on the front of a vehicle, comprising:

[0045] The housing 1 has a hollow spherical structure and an installation cavity 11 is provided inside;

[0046] The lens 2 is installed at the opening of the mounting cavity 11. The lens 2 has a reflective area 21 and a light-transmitting area 22. The light-transmitting area 22 is an arc-shaped strip and is located at the edge of the lens 2. The reflective area 21 is a mirror area. The reflective area 21 is used to reflect light to form an image. The reflective area 21 is used to observe the situation behind the vehicle or to observe the face when applying makeup.

[0047] The light-emitting device 3 is installed inside the mounting cavity 11, and the light emitted by the light-emitting device 3 shines out from the mounting cavity 11 through the light-transmitting area 22.

[0048] The control device 4 is installed in the mounting cavity 11 and is connected to the lens 2 and the light-emitting device 3. The control device 4 is used to control the opening and closing of the light-emitting device 3.

[0049] The light-emitting device 3 provides light, enabling the lens 2 to be used as a makeup mirror, increasing its flexibility and meeting different usage needs.

[0050] The modular design of the light-emitting device 3 facilitates installation, improves production efficiency, and also makes subsequent upgrades and maintenance easier.

[0051] Combination Figures 2-4 The light-emitting device 3 includes:

[0052] Mounting base 31 is installed in mounting cavity 11. Mounting base 31 is connected and fixed to housing 1 by screws or bolts or tight fit. Mounting base 31 is provided with receiving cavity 311, which has an arc-shaped strip structure.

[0053] The lighting circuit board 32 is installed in the receiving cavity 311, and the shape of the lighting circuit board 32 is adapted to the shape of the receiving cavity 311.

[0054] The light-emitting element 33 is a diode, a light bulb, or several LED beads, which is electrically connected to the lighting circuit board 32 and is used to emit light;

[0055] The light-emitting element 33 and the light circuit board 32 are both installed in the mounting base 31, and then the mounting base 31 is installed in the housing 1 for easy installation.

[0056] To improve the overall sealing of the mounting cavity 11, the light-emitting device 3 also includes a light-transmitting plate 34, which covers the receiving cavity 311 and is used to seal the opening of the receiving cavity 311. The lower edge of the light-transmitting plate 34 has a snap-fit ​​block, which is inserted into the opening of the receiving cavity 311 and abuts against the inner wall of the opening of the receiving cavity 311, so that the light-transmitting plate 34 can be installed on the mounting base 31.

[0057] In this design, the light-transmitting plate 34 is ultrasonically welded to the mounting base 31 to achieve a sealed cavity opening of the receiving cavity 311.

[0058] Combination Figure 3 and Figure 4 The mounting base 31 has a mounting port 312, which connects the receiving cavity 311 to the outside. The wires on the vehicle pass through the mounting port 312 to connect to the lighting circuit board 32.

[0059] To improve the sealing of the cavity 311, a rubber plug 5 is provided in the mounting port 312. The rubber plug 5 is used to seal the gap between the vehicle's wires and the mounting port 312. The rubber plug 5 has at least one through hole 50. The vehicle's power system wires pass through the through hole 50 to connect to the lighting circuit board 32, thereby powering the light-emitting element 33 on the lighting circuit board 32.

[0060] The inner wall of the mounting port 312 and the outer wall of the rubber plug 5 are tightly fitted together. The sealing connection is achieved by the elastic deformation of the rubber plug 5, which ensures the airtightness of the cavity 311, prevents rainwater and other liquids from entering the cavity 311, avoids the corrosion and damage of liquids to the lighting circuit board 32, and ensures the stable operation of the lighting circuit board 32 and the light-emitting element 33.

[0061] Combination Figure 4 Several protruding rings 51 are provided on the outer side wall of the rubber stopper 5. The protruding rings 51 are distributed along the length direction of the rubber stopper 5. The protruding rings 51 undergo elastic deformation to abut against the inner wall of the mounting port 312, thereby ensuring the sealing between the rubber stopper 5 and the inner wall of the mounting port 312 and avoiding gaps between the mounting port 312 and the rubber stopper 5 that would affect the sealing of the receiving cavity 311.

[0062] The control device 4 is a touch switch, which is existing technology. Specifically, the touch switch is a touch-sensitive switch or a capacitive touch switch. The mounting base 31 has a mounting groove 313. The circuit board 41 of the touch switch is installed in the mounting groove 313. The touch switch is electrically connected to the lighting circuit board 32, that is, the touch switch and the lighting circuit board 32 are connected by wires. The wires connecting the touch switch and the lighting circuit board 32 are passed through the through hole 50 of the rubber plug 5. The touch switch is used to control the opening and closing of the light-emitting element 33.

[0063] Combination Figure 1 and Figure 2 The lens 2 is provided with a touch area 23. By touching the touch area 23, the touch switch can be turned on or off, thereby enabling the touch switch to control the light-emitting element 33 to turn on and off.

[0064] To avoid accidentally turning the light-emitting element 33 on or off due to accidental touch of the touch area 23, it is necessary to press and hold the touch area 23 for several seconds (at least 2 seconds) to control the light-emitting element 33 to turn on or off.

[0065] Combination Figures 2-5 The control device 4 is connected to a heating plate 6, which is located between the mounting base 31 and the lens 2. The heating plate 6 and the mounting base 31 are connected by screws. The heating plate 6 is used to heat the lens 2 to prevent the lens 2 from fogging and affecting the reflection imaging effect.

[0066] The circuit board 41 of the control device 4 is provided with a plug interface 42, and the heating plate 6 is provided with a plug block 61. The plug block 61 is inserted into the plug interface 42 to realize the electrical connection between the heating plate 6 and the circuit board 41 of the control device 4, and the start and stop of the heating plate 6 are controlled by the control device 4.

[0067] Combination Figure 3 and Figure 5 The lower end of the heating plate 6 has a clearance area 62, which is used to avoid the control device 4, that is, to avoid the signal transmission between the touch switch and the touch area 23.

[0068] Combination Figure 1 and Figure 2 The lighting circuit board 32 is equipped with a warning light 35. The lighting circuit board 32 is connected to the radar on the rear side of the vehicle via an electrical signal. The radar on the rear side of the vehicle is connected to the vehicle's control system. The vehicle's control system is connected to the lighting circuit board 32 via a wire. When the radar on the rear side of the vehicle detects a vehicle approaching from behind, the lighting circuit board 32 receives the signal and controls the warning light 35 to emit light.

[0069] The lens 2 is provided with a warning display area 24, which is used to emit light from the warning light 35.

[0070] Combination Figure 1 and Figure 6 The housing 1 is connected to a bracket 7, which is used to install on the front of the vehicle. The bracket 7 is hollow and tubular. The wires inside the housing 1 pass through the inside of the bracket 7 and are connected to the vehicle's power system. The upper end of the bracket 7 is provided with a ball joint 71. A connector 8 is connected to the housing 1 or the mounting base 31 by screws or bolts. The connector 8 has a ball groove 81.

[0071] Under the action of external force, the edge of the spherical groove 81 undergoes elastic deformation, allowing the ball joint 71 to be inserted into the spherical groove 81. The ball joint 71 can rotate within the spherical groove 81 without disengaging, thereby realizing the universal rotation of the connector 8 on the ball joint 71, and realizing the adjustment of the angle of the housing 1 and the lens 2 on the vehicle.
