[0056] The support 2 comprises a limiting rib 21 fixed to the side wall of the shell 1, a support plate 22 arranged below the limiting rib 21 and in sliding fit with the side wall of the shell 1, and a spring 23 connected to the lower part of the support plate 22 and fixed to the bottom wall of the shell 1, and the support plate 22 is in abutment with the surface of the limiting rib 21 under the action of the spring 23;

[0057] A fixing hole 13 is formed in the bottom of the shell 1, and a fixing bolt 14 is inserted into the fixing hole 13 to connect with the mounting base surface outside to complete the fixing of the shell 1, wherein an operation hole 24 is formed in the surface of the support plate 22 corresponding to the position of the fixing hole 13;

[0058] In the actual assembly process, the shell 1 is first mounted on the automobile inner chassis and located at a relatively low position in the chassis, and is locked and fixed by the fixing bolt 14. After the shell 1 is fixed, the humidity sensor 3 is placed in the shell 1, at this time the humidity sensor 3 is acted on by the support 2, and the top of the humidity sensor 3 protrudes outside the shell 1. Then the packaging plate 4 is placed in the shell 1 through the avoiding groove 41 and forms a pressing on the humidity sensor 3, so that the humidity sensor 3 after being pressed moves towards the inside of the shell 1, and at the same time the packaging plate 4 is placed below the positioning member 11. Then the packaging plate 4 is rotated to make the positioning groove 42 on the packaging plate 4 correspondingly locked with the positioning member 11, so that the fixing of the humidity sensor 3 is completed.
