Description

Novel double-layer waterproof mobile phone shell structure TECHNICAL FIELD

[0001] The present application relates to the technical field of mobile phone accessories, and particularly relates to a novel double-layer waterproof mobile phone shell structure. BACKGROUND

[0002] Mobile phones are one of the indispensable personal carrying products in contemporary society, and with the continuous progress of the level of science and technology, the continuous development of society and the continuous improvement of people's living standards, mobile phones have become all-in-one products integrating short messages, video calls, video playing, office memos, Internet access and game terminals. In real life, if the mobile phone is used in some extreme environment, such as in the rain, or the user swims and dives with it, there will be a risk of water entering. Although waterproof protective mobile phone cases have appeared on the market, most of them use a single waterproof structure, that is, a single smooth sealing ring is used for waterproofing. Therefore, the sealing ring is prone to loosening after long-term use, especially after repeated disassembly and assembly, which will directly affect the sealing performance and lose the waterproof function.

[0003] In view of this, a novel double-layer waterproof mobile phone shell structure is proposed. TECHNICAL PROBLEM

[0013] 1. The new double-layer waterproof mobile phone shell structure, by setting double-layer protrusions at the bottom of the sealing ring, can effectively reduce defective products during production and improve the yield rate for the production enterprise; for the user, through the double-layer protrusion design, the sealing ring is deformed more after the bottom cover and the surface cover are clamped, the friction between the sealing ring and the first clamping groove bottom is also increased, preventing the sealing ring from loosening after repeated disassembly and assembly, and further preventing the problem of water leakage due to poor sealing.

Embodiment of the present application

[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.

[0028] In the description of the present application, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0029] Embodiment:

[0030] Referring to Figures 1-10, a novel double-layer waterproof mobile phone shell structure includes a bottom cover 1 and a face cover 101, both of which are made of plastic material, and the face cover 101 is provided with a transparent face plate 102 for displaying content, and the mobile phone can be operated through the face cover 101, and the buttons on the side of the mobile phone can be operated by pressing the face cover 101.

[0031] The novel double-layer waterproof mobile phone shell structure disclosed in this embodiment further includes a sealing ring 2; the bottom cover 1 is provided with a first clamping groove 201 at the top, and the face cover 101 is provided with a first recess 202 at the bottom, and the sealing ring 2 is fixed in the first recess 202 by glue, and when the sealing ring 2 is fixed in the first recess 202, the bottom of the sealing ring 2 protrudes out of the first recess 202; the bottom of the face cover 101 is clamped in the first clamping groove 201; the bottom of the sealing ring 2 abuts against the bottom of the first clamping groove 201, and the bottom of the sealing ring 2 is provided with a double-layer protrusion 3.

[0032] The so-called double-layer protrusion 3 is in the shape of a trapezoid extending downward, that is, a gap is formed between two adjacent double-layer protrusions 3.

[0033] In use, when the bottom cover 1 and the surface cover 101 are clamped, the sealing ring 2 is extruded and deformed, at this time, the trapezoidal double-layer protrusion 3 is deformed to the gap on both sides, so compared with the traditional smooth sealing ring, the sealing ring 2 used in the present application can withstand greater extrusion force, and when the same extrusion force is applied, the deformation is also greater; and the contact points of the double-layer protrusion 3 and the bottom of the corresponding first clamping groove 201 are equivalent to a layer of waterproof structure, thereby achieving the effect of double-layer waterproof, avoiding the problem of poor sealing and easy water leakage caused by the traditional smooth sealing ring after repeated disassembly and assembly.

[0034] By setting the double-layer protrusion 3 at the bottom of the sealing ring 2, the production enterprise can effectively reduce the defective products in the production process and improve the yield, because even if one of the layers has a problem, the other layer can still achieve the purpose of waterproof, increasing the fault-tolerant design concept; for the user, through the design of the double-layer protrusion 3, the sealing ring 2 is deformed more after the bottom cover 1 and the surface cover 101 are clamped, and the friction between the sealing ring 2 and the bottom of the first clamping groove 201 is also greater, preventing the sealing ring 2 from loosening after repeated disassembly and assembly, and thereby preventing the problem of poor sealing and water leakage.

[0035] As shown in FIGS. 6 and 8, the bottom of the first clamping groove 201 is provided with a second groove 301, and the number of the second groove 301 is the same as that of the double-layer protrusion 3.

[0036] Since the cross section of the double-layer protrusion 3 and the second groove 301 is in the shape of a trapezoid, and the first clamping groove 201 also functions as a guide during clamping, when the bottom cover 1 and the surface cover 101 are clamped, the double-layer protrusion 3 will be directly clamped into the second groove 301, and even if there is some deviation, the double-layer protrusion 3 will also move into the second groove 301 when the sealing ring 2 is stressed through the inclined surface of the trapezoid.

[0037] When the bottom cover 1 and the surface cover 101 are clamped, the double-layer protrusion 3 is clamped into the corresponding second groove 301 at the bottom, and the sidewall of the double-layer protrusion 3 is in contact with and abuts against the second groove 301, thereby increasing the sealing area and the friction area and further improving the sealing performance and preventing the sealing ring 2 from loosening.

[0038] The number of the double-layer protrusion 3 is two, and through the two-layer design, the trapezoidal cross section of the double-layer protrusion 3 and the second groove 301 can be larger, which ensures the sealing performance while also taking into account the stability of the double-layer protrusion 3 clamped in the second groove 301.

[0039] The sealing ring 2 is integrally formed with the double-layered protrusion 3, and is made of rubber.

[0040] The bottom of the sealing ring 2 is designed with a double-layered structure, i.e. the double-layered protrusion 3, which reinforces the sealing ring and prevents it from falling off easily when the mobile phone is disassembled.

[0041] As shown in FIGS. 9 and 10, the inner circle of the sealing ring 2 is integrally formed with first protrusions 5, the number of which is 5-10 and which are evenly distributed around the inner circle of the sealing ring 2. The sealing ring 2 is in abutment with the sidewall of the first clamping groove 201 through the first protrusions 5. As shown in FIG. 7, the sidewall of the first clamping groove 201 is provided with second protrusions 502, the number of which is 5-10 and which are evenly distributed around the sidewall of the first clamping groove 201. The sidewall of the sealing ring 2 is in abutment with the sidewall of the second protrusions 502.

[0042] The inner wall of the face cover 101 is provided with a sliding groove. When clamped, the second protrusions 502 are clamped in the sliding groove, which not only avoids interference but also plays a guiding role.

[0043] The first protrusions 5 are made of rubber, and the second protrusions 502 are made of plastic.

[0044] When the face cover 101 is clamped on the bottom cover 1, the first protrusions 5 and the second protrusions 502 can make the sealing ring 2 abut against the sidewall of the first clamping groove 201, which prevents the sealing ring 2 from loosening and improves the stability after clamping.

[0045] As shown in FIGS. 1, 9 and 10, one side of the sealing ring 2 is integrally formed with a sealing cover 501.

[0046] After the face cover 101 is clamped on the bottom cover 1, the sealing cover 501 can be inserted into the charging hole to block it when not charging, which prevents water from entering.

[0047] As shown in FIGS. 5-6, the sidewall of the first clamping groove 201 is provided with a clamping strip 4, and the sidewall of the face cover 101 is provided with a second clamping groove 401. The clamping strip 4 is clamped in the second clamping groove 401.

[0048] During the process of clamping the face cover 101 on the bottom cover 1, the sidewall of the first clamping groove 201 will first be deformed under stress, and then the clamping strip 4 is clamped in the second clamping groove 401, which prevents the face cover 101 and the bottom cover 1 from accidentally falling off during use, and also prevents the face cover 101 and the bottom cover 1 from shaking, thereby improving the sealing performance.

[0049] The bottom of the clamping strip 4 and the second clamping groove 401 is provided with an inclined surface 402, which is inclined downward to facilitate disassembly.

[0050] The above merely describes preferred specific embodiments of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art, according to the technical solution and inventive concept of the present application, makes equivalent replacement or change within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
