The appearance of the phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive of other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0025] The embodiment of the present application aims to overcome the defects and shortcomings in the prior art and to provide a shell structure that can solve the problems of ordinary waterproof structure solutions, such as complex assembly process, many components, high cost, low reliability, and the breathing effect of water in and out causing damage to the fixed interface.

[0026] In view of this, the embodiment of the present application provides a housing structure, please refer to Figure 1 , Figure 1 1 is a partial structural diagram of an embodiment of the housing structure of the present application, and the housing structure includes a housing 20, a transparent cover plate 10 and a waterproof member 30. Specifically, the housing 20 is provided with a snap-fit ​​groove 202 to form an internal space 70, and the internal space 70 is used to accommodate the display assembly 60; the transparent cover plate 10 plays a role in protecting the display assembly 60; the waterproof member 30 is used to prevent liquid from penetrating into the internal space 70 through the gap between the transparent cover plate 10 and the housing 20. Among them, the transparent cover plate 10 is covered on the housing 20, and the transparent cover plate 10 and the housing 20 are snap-fitted, and the waterproof member 30 is provided in the snap-fit ​​groove 202 and sandwiched between the transparent cover plate 10 and the housing 20.

[0027] like Figure 1 As shown, the housing 20 includes an inner side wall 201 and a snap-in groove 202, the inner side wall 201 includes a first inner side wall 2010 and a second inner side wall 2011, the snap-in groove 202 includes a first snap-in groove 2020 and a second snap-in groove 2021, the first inner side wall 2010 is located at the side of the transparent cover plate 10, surrounds the transparent cover plate 10, and the second inner side wall 2011 is pressed by the transparent cover plate 10, the first inner side wall 2010 and the second inner side wall 2011 form a vertical relationship, and snap-in the transparent cover plate 10. The snap-in groove 202 is used to accommodate the waterproof member 30, the opening of the first snap-in groove 2020 is located at the first inner side wall 2010, and the opening of the second snap-in groove 2021 is located at the second inner side wall 2011.

[0028] Please refer to Figure 1 The transparent window includes an upper surface 102, a lower surface 103 and a side wall 101. The transparent window can be but is not limited to tempered glass, a mirror, etc. The side wall 101 of the transparent cover 10 includes a first side wall section 1010 and a second side wall section 1011. The first side wall section 1010 and the second side wall section 1011 are both annular surfaces. The first side wall section 1010 is an inclined oblique annular surface, and the second side wall section 1011 is a vertical annular surface parallel to the first inner side wall 2010; the upper surface 102 is connected to the first side wall section 1010 and directly faces the external environment; the lower surface 102 is connected to the second inner side wall 2011 and faces the internal space 70.

[0029] The waterproof member 30 includes a first waterproof member 301 and a second waterproof member 302. The first waterproof member 301 and the second waterproof member 302 may be, but are not limited to, waterproof rubber rings and are installed with a certain initial pressure. The first waterproof member 301 is clamped by the first clamping groove 2020, and the second waterproof member 302 is clamped by the second clamping groove 2021. Figure 1As shown, the first waterproof member 301 contacts the first side wall 101 and generates oblique pressure on the transparent cover plate 10 through the oblique surface to prevent the transparent cover plate 10 from protruding; the second waterproof member 302 contacts the lower surface 103 of the transparent cover plate 10 and is pressed by the transparent cover plate 10 due to its own weight. When external pressure is transmitted, the first waterproof member 301 will generate downward pressure due to contact with the outside world, and this pressure will press the first waterproof member 301 and the first side wall 101 tightly, so that there will be no gap between the first waterproof member 301 and the first side wall 101, forming a first waterproof. At the same time, the external pressure will press the transparent cover plate 10 and the second waterproof member 302 tightly, so that there will be no gap between the transparent cover plate 10 and the second waterproof member 302, forming double waterproofing with strong waterproof performance.

[0030] In the traditional solution, the pressure of the water flow is changing, but the pressure of the internal space 70 is constant, so the pressure difference between the inside and the outside will also change continuously, so the external pressure on the waterproof part 30 will also change continuously. This constantly changing breathing effect may damage the waterproof interface.

[0031] Based on this, Figure 1 As shown, a closed cavity 50 is formed between the first waterproof part 301, the second waterproof part 302, the inner side wall 201 of the housing 20 and the side wall 101 of the transparent window; before entering the water, the first waterproof part 301 and the second waterproof part 302 are designed and assembled to ensure that they have initial pressure and a closed cavity 50 is formed between them. After entering the water, it will be subjected to the pressure P brought by the external environment, and the pressure of each part will have the following corresponding relationship, PA = P + K * Pv1

[0032] P = PA + K * PO2 (K is the medium pressure transmission coefficient)

[0033] Therefore: Pinner=P+K(PO1+PO2), Pinner>>P

[0034] The air pressure in the closed cavity 50 is PA, the pressure applied by the first waterproof member 301 is PO1, the pressure applied by the second waterproof member 302 is PO2, and the air pressure in the internal space 70 is Pinside;

[0035] P is affected by the superposition of the first waterproof member 301 and the second waterproof member 302, and its water pressure resistance is more effective than that of a single waterproof member 30. Moreover, as P increases or decreases, the volume of the closed cavity 50 will increase or decrease, which will also cause PA to increase or decrease. That is, as P increases or decreases, PA also increases or decreases synchronously, so PO1 and PO2 remain relatively stable, which can effectively avoid damage caused by the breathing effect.

[0036] At the same time, if Figure 2 As shown, Figure 21 is a schematic diagram of the structure of an embodiment of the housing structure of the present application. The housing 20 of the housing structure is provided with a sensor assembly 40 on the side (the bottom surface 203 of the housing) opposite to the transparent cover plate 10. The sensor assembly 40 comprises a water depth sensor 401 and a water depth sensor waterproof ring 402. The water depth sensor 401 can monitor the pressure of the water flow and judge the water depth at this time by the magnitude of the pressure, while the water depth sensor waterproof ring 402 is used to prevent liquid from penetrating into the sensor assembly 40. A through hole 403 is provided on the bottom surface 203 of the housing. The through hole 403 is used to allow water to flow into the water depth sensor 401, so that the water depth sensor 401 can judge the water depth by the pressure of the water flow.

[0037] At the same time, if Figure 2 As shown, the water depth sensor waterproof ring 402 includes a first water depth sensor waterproof ring 4020 and a second water depth sensor waterproof ring 4021. The first water depth sensor waterproof ring 4020 and the second water depth sensor waterproof ring 4021 are arranged in the through hole 403. There is also a closed cavity 50 between the first water depth sensor waterproof ring 4020 and the second water depth sensor waterproof ring 4021. The function is the same as the closed cavity 50 formed by the first waterproof component 301 and the second waterproof component 302. It can not only play a double waterproof role, but also can effectively avoid the damage caused by the breathing effect.

[0038] In addition, this application provides a diving display device, please refer to Figure 3 , Figure 3 1 is a schematic diagram of the structure of an embodiment of a diving display device of the present application, which can be a diving watch, a diving display, etc., and includes a display assembly 60 and the above-mentioned housing structure. The display assembly 60 is arranged in the internal space 70, and is used to display information and convey it to the user through the transparent cover plate 10. The display assembly 60 includes a display screen 601 and a display main board 602. The display screen 601 is connected to the transparent cover plate 10 by a connector 603, and the display main board 602 is located below the display screen 601.

[0039] The diving display device provided by the embodiment of the present application can not only achieve double waterproofing of the internal waterproof parts during diving, but also prevent the waterproof interface from being damaged due to the breathing effect. At the same time, it is easy to install, does not require screw fixation, and does not require complex tooling for glue fixation, and can be completed by assembling two waterproof parts 30. It has low cost, simple structure and few parts.

[0040] The above descriptions are only some embodiments of the present application, and do not limit the protection scope of the present application.
