Detailed Description of the Embodiment

[0022] The following further describes the present application in detail with reference to the drawings.

[0023] An embodiment of the present application discloses a sensor fixing structure.

[0024] Referring to Figure 1 and Figure 2 , the sensor fixing structure includes a sensor main body 1 and an assembly board 2. In this embodiment, the sensor main body 1 is a temperature sensor, and the assembly board 2 is made of an insulating material. The sensor main body 1 further includes a detection member 10 for contacting the glass surface, and the temperature information of the glass surface is obtained through the detection member 10. A limiting seat 3 is integrally formed on the assembly board 2. The limiting seat 3 and the surface of the assembly board 2 jointly enclose a receiving cavity 20 for receiving the sensor main body 1, and the sensor main body 1 is arranged in the receiving cavity 20.

[0025] As Figure 1 and Figure 2 shown, a plurality of claws 4 are also integrally formed on the limiting seat 3. The number of claws 4 can be increased or decreased according to the actual size of the sensor main body 1. In this embodiment, the number of claws 4 is two, and the claws 4 are symmetrically arranged on both sides of the receiving cavity 20. The two claws 4 on both sides are used to limit and fix the sensor main body 1 in the receiving cavity 20. When installing the sensor main body 1, by aligning the sensor main body 1 and pressing it into the limiting seat 3, under the limitation of the two claws 4 on both sides, the sensor main body 1 can be quickly and firmly installed on the assembly board 2. In addition, since the overall thickness of the assembly board 2 is relatively thin, it can be better adapted to the installation in a narrow space, improving the sensor installation efficiency and reducing the installation difficulty at the same time.

[0026] As Figure 3 and Figure 4 shown, a plurality of wire grooves 5 are provided on the side wall of the assembly board 2 facing away from the limiting seat 3. The wire grooves 5 are arranged in parallel with each other, and the wire grooves 5 are used to limit and fix the wires in the assembly board 2. A card slot 6 communicating with the wire grooves 5 is also provided on the assembly board 2. The length extension direction of the wire groove 5 is perpendicular to the length extension direction of the card slot 6. The card slot 6 can also clamp and fix the wires, and the opening of the card slot 6 can supply the end of the wire to extend from the outer side wall of the assembly board 2 to the outside of the assembly board 2. A welding terminal 9 is provided at the end of the wire and located outside the assembly board 2. The welding terminal 9 is used to press and fix the end of the wire of the external electrical device, so as to establish signal transmission. The arrangement of the wire grooves 5 and the card slot 6 facilitates the routing of the wires, and at the same time can guide the wires to be arranged along the specified path, preventing the wires from interfering with the glass surface.

[0027] As Figure 3 and Figure 4As shown, the assembly plate 2 is vertically penetrated with a through hole 21 located on one side of the limit seat 3, and the end of the detection member 10 away from the sensor body 1 is bent toward the direction close to the through hole 21 and extends into the through hole 21. The assembly plate 2 is integrally formed with a limit plate 7, which partially blocks the through hole 21, and the limit plate 7 is used to limit the detection member 10 in the through hole 21, thereby preventing the detection member 10 from escaping from the through hole 21.

[0028] If Figure 3 、 Figure 4 As shown in FIG. 1 , the end of the through hole 21 away from the limiting seat 3 penetrates the outer wall of the assembly plate 2 and forms a clearance opening 23, which is directly opposite to the end of the detection member 10. When the overall length of the detection member 10 is relatively long, the setting of the clearance opening 23 allows the end of the detection member 10 to extend from the through hole 21, thereby ensuring the smooth installation of the detection member 10.

[0029] If Figure 3 、 Figure 4 As shown in FIG. 1 , a clearance groove 22 is provided on the side wall of the assembly plate 2 away from the limiting plate 7, and a tape layer 8 circumferentially arranged around the through hole 21 is fixedly provided on the inner side wall of the clearance groove 22. The tape layer 8 can be made of double-sided tape, and the tape layer 8 is used to bond and fix the assembly plate 2 to the glass.

[0030] The implementation principle is: when installing the sensor body 1, by aligning the sensor body 1 with the accommodating cavity 20 and pressing it into the limiting seat 3, the sensor body 1 can be quickly and securely installed on the assembly board 2 under the limitation of the claws 4 on both sides. In addition, since the overall thickness of the assembly board 2 is relatively thin, it can be better adapted to installation in a small space, which improves the sensor installation efficiency and reduces the installation difficulty.

[0031] The arrangement of the buried wire groove 5 and the clamping groove 6 facilitates the routing of the wires and can also guide the wires to be laid out along a specified path to prevent interference between the wires and the glass surface. The limiting plate 7 is used to limit the detection member 10 in the through hole 21, thereby preventing the detection member 10 from detaching from the through hole 21 and ensuring that the detection member 10 can stably contact the glass.

[0032] The above are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.​​​​
