DETAILED DESCRIPTION

[0040] 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 present application. 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.

[0041] See also Figure 1 and Figure 2 , this application provides the following technical solutions:

[0042] A sensor installation structure includes an inner shell 1, an outer shell 2 and a cover 3, wherein the inner shell 1 is provided with a cavity for placing a sensor circuit board 100, and the inner shell 1 is used to place the sensor circuit board 100. The top of the outer shell 2 is an open end, and a placement groove 21 corresponding to the inner shell 1 is provided inside the outer shell 2, and a positioning structure 22 corresponding to the inner shell 1 is provided on the inner circumference of the placement groove 21; a connection structure 23 is provided on the outer shell 2 for facilitating its connection with external equipment; both the inner shell 1 and the outer shell 2 are provided with through holes for facilitating the sensor to sense the external environment.

[0043] The cover body 3 is arranged at the lower side of the outer shell 2, and an opening is arranged at the upper part of the cover body 3, and the lower part of the outer shell 2 is covered at the opening. The cover body 3 is a box structure with an open upper end, and vent holes are arranged on the lower side of the cover body 3; a snap-fit ​​structure is arranged between the cover body 3 and the outer shell 2, and when the cover body 3 and the outer shell 2 are combined, a gap is left between the lower surface of the outer shell 2 and the inner bottom surface of the cover body 3.

[0044] Through the structure of this solution, the outer shell 2 is connected to the structure of the installation environment of the sensor application, and the cover 3 can provide the first layer of barrier for the droplets in the environment, and the outer shell 2 and the inner shell 1 respectively have a double barrier effect. Figure 2 As shown, there is a gap between the cover body 3 and the outer shell 2. If there are droplets or water mist entering the cover body 3, the outer shell 2 will not be directly soaked, and the sensor circuit board 100 will not be affected.

[0045] Based on the above implementation scheme, see Figure 3The inner shell 1 includes a half part 11 and a half part 2 12, both of which are box bodies. The lower side of the half part 11 is an open mouth, and the upper side of the half part 2 12 is an open mouth. After the half part 2 12 and the half part 1 1 are assembled, a cavity corresponding to the sensor circuit board 100 is formed, and a threading hole corresponding to the sensor circuit board 100 is reserved on one side after the half part 2 12 and the half part 1 1 are assembled. A plurality of through holes are provided at the bottom of the half part 2 12, and the through holes are distributed in a rectangular array, and a filter is provided at the array structure formed by the through holes. A slot is provided along the edge of the half part 2 12, and the slot is a recessed mechanism extending downward; a plug-in board is provided at the side of the half part 11 corresponding to the slot, and when the half part 1 11 and the half part 2 12 are plugged in, the plug-in board is embedded in the slot. A plurality of plug holes are provided in the slot of the half part 2 12, and a plurality of plug posts are provided at the lower side of the half part 11 corresponding to the plug holes.

[0046] Four semicircular slots are correspondingly arranged on one side of half part 11 and half part 2 12 as threading holes, and a stepped structure is correspondingly arranged on both sides, and the lower horizontal side of the stepped structure of half part 2 12 is the outer side, and the stepped structures of half part 11 and half part 2 12 can fit together.

[0047] This structure facilitates the installation of the inner shell 1 and the sensor circuit board 100 , and at the same time makes the inner shell 1 excluding the through hole have a good waterproof effect, making it difficult for water vapor to enter, thereby extending the service life of the sensor circuit board 100 .

[0048] Based on the above implementation scheme, see Figure 4 A plurality of through holes are provided on the bottom of the placement groove 21 , and the positions of the through holes on the placement groove 21 correspond to the positions of the through holes in the inner shell 1 .

[0049] The positioning structure 22 of the outer shell 2 includes a lower positioning member 221, an upper positioning member 222 and a side positioning member 223. The lower positioning member 221 is arranged at the lower inner part of the placement groove 21, and can form an upward supporting force for the inner shell 1, and a gap is left between the lower positioning member 221 and the inner bottom surface of the placement groove 21; the upper side surface of the upper positioning member 222 is an inclined surface, and the lower side surface is a plane, which can limit the upper side surface of the inner shell 1; when the inner shell 1 is embedded in the placement groove 21, the lower side surface of the upper positioning member 222 is located above the upper side surface of the inner shell 1; the upper side surface of the side positioning member 223 is an inclined surface, and the horizontal side of the side positioning member 223 is a vertical surface. When the inner shell 1 is embedded in the placement groove 21, the horizontal side surface of the side positioning member 223 abuts against one end of the inner shell 1.

[0050] The entire positioning structure 22 is formed by three different positioning members, so that the inner shell 1 can obtain a stable supporting force inside the placement groove 21, which can improve the integrity of the outer shell 2 and the inner shell 1 after assembly.

[0051] On the basis of the above implementation scheme, the placement groove 21 is a rectangular groove body, and two lower positioning members 221 are respectively provided on two parallel side walls of the placement groove 21; and the upper positioning members 222 are respectively provided on the four groove walls of the placement groove 21. Figure 4 As shown, an upper positioning member 222 is disposed between the two lower positioning members 221, and an upper positioning member 222 is also disposed on the groove wall adjacent to the lower positioning member 221. The structures of the upper positioning members 222 at the two positions are slightly different, but overall, both conform to the structure that the upper side surface is an inclined surface and the lower side surface is a flat surface. The side positioning member 223 is disposed on the groove wall opposite to the upper positioning member 222.

[0052] This solution supplements the specific distribution form of the various components of the positioning structure 22. Through this form, while satisfying the positioning of the inner shell 1, the installation process of the inner shell 1 is also very simple. It only needs to insert the inner shell 1 into the placement groove 21 from the side of the side positioning piece 223 and make it snap-fit.

[0053] On the basis of the above-mentioned implementation scheme, the connection mechanism 23 is arranged on the outer wall of the placement groove 21 and extends toward both sides of the placement groove 21. The connection structure 23 includes two connection plates 231, which are horizontally arranged plates with mounting holes on the plate body. The outer shell 2 can be connected to the external device through the mounting holes on the connection plates 231; two reinforcing plates 232 are respectively arranged corresponding to each connection plate 231, and the reinforcing plates 232 are fixedly arranged on both sides of the connection plate 231. The reinforcing plates 232 are right-angled trapezoidal structures, and the lower side thereof is fixedly connected to the connection plate 231, and the horizontal side is fixedly connected to the outer wall of the placement groove 21. An outer limiting plate 233 is also arranged on the outer side of the placement groove 21. When the cover body 3 and the outer shell 2 are combined, a sealing pad 4 is arranged between the upper edge of the cover body 3 and the outer limiting plate 233.

[0054] like Figure 5 As shown, four card interfaces are provided on the side wall of the cover body 3, and four card blocks are correspondingly provided on the outer wall of the outer shell 2, the outer side wall of the card block is an inclined surface, and the upper end surface is a plane.

[0055] Through the structure of this solution, the operation process of combining the cover body 3 and the outer shell 2 can be simplified, and it is ensured that the connection between the two has good waterproofness.

[0056] Based on the above, this design adopts the combination of internal and external double shells, as well as the staggered design of air through holes and gravity drain groove design, so that the sensor module has better splash-proof ability and prevents the sensor circuit board from being touched by running water. While ensuring the normal function of sensing temperature and humidity, it can achieve high production efficiency and lower overall cost.

[0057] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
