[0041] like Figure 4 , Figure 5 as well as Figure 6 As shown, the display component 200 includes a lens frame 210 and a lens body 220. The lens frame 210 is disposed around the lens body 220 and connected to the lens body 220. The lens frame 210 includes a third annular plate 211 disposed around the lens body 220 and a fourth annular plate 212 located outside the third annular plate 211, that is, located outside the third annular plate 211 away from the lens body 220. The third annular plate 211 and the fourth annular plate 212 are spaced apart and form a first clearance groove 213.

The fourth annular plate 212 and the first potting groove 124 are nested together, and the first annular plate 122 and the first clearance groove 213 are nested together. At this time, the fourth annular plate 212 and the first potting groove 124 squeeze the sealant, so that after the sealant dries, a first waterproof potting part connecting the fourth annular plate 212 and the first potting groove 123 is formed.

[0046] In the above embodiments, by providing a first annular plate 122, a second annular plate 123, and a first potting groove 124 on the cover plate 120 of the housing 100, and by providing a third annular plate 211, a fourth annular plate 212, and a first clearance groove 213 on the lens frame 210 of the display assembly 200, when the display assembly 200 is assembled with the cover plate 120 of the housing 100, the fourth annular plate 212 and the first potting groove 124 are nested together, and the first annular plate 122 and the first clearance groove 213 are nested together. By potting glue between the fourth annular plate 212 and the first potting groove 124, a first waterproof potting part is formed. Through the nested potting method, on the one hand, the stability of the assembly of the display assembly 200 and the cover plate 120 is improved, and on the other hand, the waterproof capability is effectively improved, preventing water from seeping into the receiving cavity 110 from the assembly gap between the display assembly 200 and the housing 100, so that the entire waterproof lens assembly 10 has good waterproof performance.

[0051] like Figure 6 As shown, the lens frame 210 also includes a fifth annular plate 216 disposed away from the first clearance groove 213, that is, the fifth annular plate 216 is disposed on the side of the lens frame 210 facing the center of the receiving cavity 110, and the fifth annular plate 216 is disposed at a distance from the second annular plate 123.

[0052] The lens frame 210 also includes an inclined annular plate 217 connecting the fifth annular plate 216 and the fourth annular plate 212; wherein, a second waterproof glue-filling part (not shown) is connected between the fifth annular plate 216, the second annular plate 123 and the inclined annular plate 217.

[0053] In an optional scenario, after the display component 200 is assembled onto the housing cover plate 120 from one side of the receiving cavity 110, a second pouring groove 126 is formed between its fifth annular plate 216, second annular plate 123 and inclined annular plate 217. Subsequently, after sealant is poured into the second pouring groove 126, the sealant will form a second waterproof filling part after it dries.

[0054] In an optional embodiment, the second waterproof glue-filling part is connected to the first waterproof glue-filling part.

[0055] Optionally, the first fastener 214 is disposed on the fifth annular plate 216 and / or the inclined annular plate 217.

[0070] Optionally, the outer side of the PCB board 300 can abut against the inner side of the shell side plate 130, or it can be spaced apart from the inner side of the shell side plate 130. The PCB board 300 abuts against the boss portion 131 at least partially, so that the outer side of the PCB board 300 and the shell side plate 130 can form a gap. After potting, the waterproof potting layer can effectively connect the PCB board 300 and the shell side plate 130, thereby improving the waterproof performance of the entire waterproof lens assembly 10.
