After the shaft 204 of the temperature sensing device 20 is inserted through the mounting hole 101, the shaft 204 of the temperature sensing device 20 is fixed to the lower surface 10b of the heat generating plate 10 by the bearing clip 22. In a specific implementation, the hole 222 in the middle of the annular portion 220 of the bearing clip 22 is directed toward the bottom 203 of the temperature sensing device 20, the bearing clip 22 is directly sleeved on the shaft 204 of the temperature sensing device 20 from the bottom 203 of the temperature sensing device 20 in such a manner that the first end 2211 of the elastic card 221 is close to the bottom 203 of the temperature sensing device 20 and the second end 2212 of the elastic card 221 is far from the bottom 203 of the temperature sensing device 20, and the bearing clip 22 is moved along the shaft 204 of the temperature sensing device 20 to a position between the stop surface 2021 of the step 202 of the temperature sensing device 20 and the lower surface 10b of the heat generating plate 10, the annular portion 220 of the bearing clip 22 is located on the lower surface 10b side of the heat generating plate 10, and the elastic card 221 is located on the stop surface 2021 side of the.

In this embodiment, the bearing clip 22 includes a plurality of elastic clamping pieces (221), the elastic clamping pieces (221) are arranged along the circumference of the annular portion (220), the second ends 2212 of the elastic clamping pieces 221 of the bearing clip 22 enclose a circle under the inside of the hole 222 in the central area of the annular portion 220, and when the bearing clip 22 is not pressed, the diameter of the circle is smaller than the width K of the shaft portion 204 of the temperature sensing device 20, specifically, the diameter of the circle is greater than or equal to 4 mm and less than or equal to 10 mm, the width of the shaft portion 204 is greater than or equal to 4 mm and less than or equal to 10.6 mm, and the difference between the width of the shaft portion (204) and the diameter of the circle is greater than 0 mm and less than or equal to 0.6 mm.

Further, in the present embodiment, the inclined guide surface 2212 is provided at the lower end of the step 202 of the temperature sensing device 20, so that the bearing clip 22 can easily pass through the step 202 of the temperature sensing device 20 to reach the side of the stop surface 2021 of the step 202. When the bearing clip 22 reaches the stopper surface 2021 side of the step 202 of the temperature sensing device 20, the elastic tab 211 of the bearing clip 22 contracts and comes into close contact with the shaft portion 204 of the temperature sensing device 20, and a frictional force is generated between the elastic tab 211 of the bearing clip 22 and the shaft portion 204 of the temperature sensing device 20, and this frictional force prevents the bearing clip 22 from sliding along the shaft portion 204 of the temperature sensing device 20 toward the bottom portion 203 of the temperature sensing device 20.

In this embodiment, the distance H between the stop surface 2021 of the step 202 of the temperature sensing device 20 and the lower surface 10b of the heating plate 10 is designed to be smaller than the height z of the bearing clip 22 in the non-stressed state, when the bearing clip 22 is located between the stop surface 2021 of the step 202 of the temperature sensing device 20 and the lower surface 10b of the heating plate 10, the elastic card 221 is compressed in the direction of L1, the elastic card 221 generates an elastic force in the direction of L2, the elastic force acts on the step 202 of the temperature sensing device 20, so that the step 202 of the temperature sensing device 20 is stressed in the direction of L2, the top 201 of the temperature sensing device 20 is pulled in the direction of L2, and the top 201 of the temperature sensing device 20, the elastic sealing ring 23 and the upper surface of the heating plate 10 are in a tightly adhered state.

The elastic sealing ring 23 is arranged between the top 201 of the temperature sensing device 20 and the upper surface of the heating plate 10, and the elastic sealing ring 23 can improve the sealing performance between the top 201 of the temperature sensing device 20 and the heating plate 10, and prevent the occurrence of air leakage and water leakage due to the gap between the top 201 of the temperature sensing device 20 and the heating plate 10. In a preferred embodiment, the top 201 of the temperature sensing device is recessed to form a mounting space 205, and the elastic sealing ring 23 is mounted in the mounting space 205.

In this embodiment, when a loose gap occurs between the top 201 of the temperature sensing device 20 and the heat generating plate 10, the loose gap can be compensated from two aspects.

On the other hand, when a loose gap is formed between the top 201 of the temperature sensing device 20 and the heating plate 10, the pressure applied to the elastic sealing ring 23 between the top 201 of the temperature sensing device 20 and the upper surface of the heating plate 10 is reduced and expanded, thereby compensating the gap between the top 201 of the temperature sensing device 20 and the heating plate 10 and maintaining the tight sealing state between the top 201 of the temperature sensing device 20 and the heating plate 10.

On the other hand, when the bearing clip 22 is compressed inward in the direction L1 and a loose gap is formed between the top 201 of the temperature sensing device 20 and the heat generating plate 10, the elastic clamping piece 221 of the bearing clip 22 expands in the direction L2 to compensate for the gap formed between the top 201 of the temperature sensing device 20 and the heat generating plate 10, so that the top 201 of the temperature sensing device 20 and the heat generating plate 10 are kept in a tightly sealed state.

Compared with the prior art, the shaft part 204 of the temperature sensing device 20 of the application only needs to be provided with the step 202, tapping and vehicle flat position are not needed, and production complexity is greatly reduced. Meanwhile, compared with the combination of nuts and gaskets in the prior art, the bearing clamp 22 in the present application is relatively low in cost, and can overcome the problem that the nuts are easy to loosen, so that the loosening condition between the temperature sensing device 20 and the heating plate 10 occurs.

It should be emphasized that the above-described embodiments are merely exemplary of the present application, and should not be construed as limiting the present application.

For example, in another embodiment, a gasket having a certain height is disposed between the lower surface of the heat generating plate 10 and the bearing clip 22, and the annular portion 220 of the bearing clip 22 abuts against the gasket, in this embodiment, it is not required that the height H between the lower surface 10b of the heat generating plate 10 and the stop surface 2021 of the step 202 of the temperature sensing device 20 is less than the height Z of the bearing clip 22 when no pressure is applied, and it is only required that the distance between the lower surface of the gasket and the upper surface of the step 202 of the temperature sensing device 20 is less than the height Z of the bearing clip 22.

For another example, in another embodiment, the step 202 of the temperature sensing device 20 is a ring structure with adjustable diameter, and a hole is provided in the middle of the ring structure, and the step 202 of the temperature sensing device can be separated from the shaft 204. After the diameter of the step 202 is adjusted to be larger than the diameter of the shaft 204, the step 202 is movable up and down along the shaft 204, and after the step 202 is moved to a proper position of the shaft 204, the diameter of the step 202 is adjusted to be a small value so as to be in close contact with the shaft 204 of the temperature sensing device 20 and fixed to a certain position of the shaft 204. In this embodiment, when the temperature sensing device 20 is mounted, the step 202 of the temperature sensing device 20 may be removed from the shaft 204 of the temperature sensing device 20, and after the shaft 204 of the temperature sensing device 20 passes through the mounting hole 101, the step 202 of the temperature sensing device may be put on the shaft 204 of the temperature sensing device 20 from the bottom 203 of the temperature sensing device 20. In this embodiment, the outer width X of the step 202 of the temperature sensing device 20 has no influence on the width W of the mounting hole 101.
