Inner rear-view mirror integrated with rainfall sensor

Abstract

The utility model discloses an inside rear-view mirror integrated with a rain sensor, which comprises a mirror body, a ball head support arranged on the back of the mirror body, a hollow support cavity arranged inside the ball head support, an integrated rain sensor arranged in the support cavity, the integrated rain sensor comprising a circuit mainboard, a main controller arranged on the circuit mainboard, and a power supply connected with the main controller. One side of the main controller is provided with a pair of infrared transmitting tubes, the other side of the main controller is provided with a pair of infrared receiving tubes, and the infrared transmitting tubes and the infrared receiving tubes are respectively provided with a detachable light condensation strip. When rainfall detection is carried out, the infrared transmitting tube of the integrated rainfall sensor transmits infrared rays, and the transmitted infrared rays sequentially penetrate through a windshield and raindrops. The main controller judges the current rainfall by comparing and calculating the intensity of the emergent light and the intensity of the reflected light. As the integrated rainfall sensor is directly mounted at the opening of the ball head bracket, the effective utilization of space is realized, and the overall performance and reliability of the system are also improved.

[0009] Compared with the prior art, the utility model has the following beneficial effects:

[0010] The present utility model provides an interior rearview mirror integrated with a rain sensor. When rain detection is carried out, an infrared emitting tube of the integrated rain sensor emits infrared rays. After passing through the condenser strip on the infrared emitting tube, the emitted infrared rays sequentially pass through the windshield and raindrops, and then reach the condenser strip and the infrared receiving tube on the infrared receiving tube through reflection. The main controller judges the current rainfall by comparing and calculating the intensities of the emitted light and the reflected light. Since the integrated rain sensor is directly installed at the opening of the ball head bracket and closely detects against the windshield, it not only realizes the effective utilization of space, but also improves the overall performance and reliability of the system, and has strong practicability.

[0023] In order to enable those skilled in the art to better understand the solution of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] As Figures 1 to 3 shown, the interior rearview mirror 1 with an integrated rain sensor includes a mirror body 2, a ball head bracket 3 is provided on the back of the mirror body 2, the mirror body 2 is rotatably arranged on the ball head bracket 3, a hollow bracket cavity 31 is provided inside the ball head bracket 3, and an integrated rain sensor 4 is provided in the bracket cavity 31.

[0025] In addition, a circular sealing ring groove 32 is provided at the opening of the bracket cavity 31.

[0026] As Figure 4 and Figure 5 shown, the integrated rain sensor 4 includes a circuit main board 41, a main controller 40 is provided on the circuit main board 41, a pair of infrared emitting tubes 42 is provided on one side of the main controller 40, a pair of infrared receiving tubes 43 is provided on the other side of the main controller 40, and a detachable condensing strip 44 is provided on both the infrared emitting tube 42 and the infrared receiving tube 43.

[0027] As Figures 6 to 8 shown, the condensing strip 44 includes a long strip-shaped condensing main body 440, a wedge-shaped condensing ridge 442 is provided at the top of the condensing main body 440, and a pair of lamp bead cover holes 441 is provided at the bottom of the condensing main body 440.

[0028] It should be noted that the condensing strip 44 is integrally formed of plexiglass.

[0029] The installation method of the interior rearview mirror 1 with an integrated rain sensor will be described below.

[0030] As Figure 9As shown, the ball head bracket 3 is directly fixed to the windshield 5. By using the sealing ring groove 32, the sealing performance between the opening of the ball head bracket 3 and the windshield 5 can be effectively improved.

[0031] As Figure 10 shown, when rain detection is performed, the infrared emitting tube 42 of the integrated rain sensor 4 emits infrared rays. After passing through the condenser strip 44 on the infrared emitting tube 42, the emitted infrared rays sequentially pass through the windshield 5 and raindrops 6, and then reach the condenser strip 44 and the infrared receiving tube 43 on the infrared receiving tube 43 through reflection. The main controller 40 determines the current rainfall by comparing and calculating the intensities of the emitted light and the reflected light.

[0032] Since the integrated rain sensor 4 is directly installed at the opening of the ball head bracket 3 and detects closely to the windshield 5, it not only realizes the effective utilization of space, but also improves the overall performance and reliability of the system, and has strong practicability.

[0033] Obviously, the embodiments described above are only a part of the embodiments of the present application, rather than all the embodiments. The preferred embodiments of the present application are given in the drawings, but they do not limit the patent scope of the present application.
