[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] See also Figure 1-7 In the embodiment of the utility model, the automobile rearview mirror temperature sensor comprises

[0039] The housing 1 has a sensor probe 2 for detecting the temperature of a rearview mirror of an automobile disposed therein, and a tightening assembly 5 is disposed below the sensor probe 2; the sensor probe 2 is electrically connected to a sensor chip 3; and a data line 4 is connected to the sensor chip 3.

[0040] It is further explained that the existing automobile rearview mirror temperature detection has been standardized, and a cavity is provided at the outer end of the rearview mirror housing to facilitate the probe to be protruded. The housing 1 in this embodiment can be directly installed inside the rearview mirror housing, thereby realizing a hidden installation and ensuring the simplicity of the rearview mirror appearance.

[0041] By adopting the above technical solution, the sensor probe 2 is fixed inside the housing 1 through the tightening component 5; the sensor probe 2 transmits the detected temperature to the sensor chip 3, and after information processing, the sensor chip 3 transmits the data to the central control system through the data line 4.

[0042] In this embodiment, the tightening assembly 5 comprises a support cover 51 , a spring 52 and a bottom cover 53 ; the spring 52 is arranged between the support cover 51 and the bottom cover 53 .

[0043] By adopting the above technical solution, since the sensor probe 2 is installed inside the probe shell 12, after installation, there is a certain gap between the sensor probe 2 and the bottom of the shell 11, which is not convenient for fixing the sensor probe 2; for this reason, we use the spring 52 to lift the sensor probe 2 to install it, which has a simple structure and is easy to disassemble and assemble.

[0044] In this embodiment, the bottom of the support cover 51 and the top of the bottom cover 53 are both provided with cavities for facilitating the installation of the spring 52 .

[0045] By adopting the above technical solution and setting the cavity, the fixing stability of the spring 52, the supporting cover 51 and the bottom cover 53 is increased.

[0046] In this embodiment, an arc-shaped groove is provided on the support cover 51 for the wire at the bottom of the sensor probe 2 to pass through, and the upper surface of the support cover 51 is in contact with the bottom of the sensor probe 2 .

[0047] By adopting the above technical solution and setting the arc groove, it is convenient to pass the wire at the bottom of the sensor probe 2, and avoid the wire being damaged due to long-term pressure.

[0048] In this embodiment, the housing 1 comprises a shell 11 , on which a probe shell 12 is integrally provided for accommodating the sensor probe 2 ; a threading hole 13 is provided at one end of the shell 11 for accommodating the data cable 4 to pass through.

[0049] In this embodiment, a wire clip 15 is disposed inside the housing 11 . The wire clip 15 is located inside the wire threading hole 13 , and an arc groove is formed on the wire clip 15 .

[0052] By adopting the above technical solution, the sensor chip 3 can be stably fixed on the fixing column 14 by screws.

[0053] In this embodiment, the housing 11 is clamped with the side housing 6 , and the side housing 6 is fixed to the housing 11 by screws.

[0054] The working principle of the utility model is as follows: during installation, the sensor probe 2 is first inserted into the probe shell 12, and then the tightening assembly 5 is placed at the bottom of the sensor probe 2; the bottom cover 53 fits the bottom of the shell 11, and the spring 52 lifts the support cover 51 according to its own elasticity, thereby lifting the sensor probe 2; an arc-shaped groove is provided above the support cover 51 for the wire at the bottom of the sensor probe 2 to pass through, so that the wire at the bottom of the sensor probe 2 can be easily passed out, thereby avoiding damage to the wire caused by long-term pressure.

[0055] The utility model can be directly installed inside the rearview mirror housing, and the data line 4 is arranged and wired following the line arrangement of the turn signal light of the rearview mirror and connected to the central control, thereby realizing hidden installation and ensuring the simplicity of the appearance of the rearview mirror.
