Description

Technical Field

[0001] This utility model relates to the field of heat shrink film, specifically to a thin film protective structure for an electronic wristband. Background Technology

[0002] There are areas for improvement in the packaging protection of circular consumer electronics such as smart bracelets. Generally, for relatively inexpensive smart bracelets, only a single layer of circular heat-shrink film is used for protection. Alternatively, only a thin film protects the screen. Neither of these methods is comprehensive. In particular, the heat-shrink film that wraps tightly around the entire smart bracelet results in wrinkles that affect the appearance, and because the film adheres tightly to the bracelet, it's not very convenient to tear or remove. Utility Model Content

[0003] The problem to be solved by this utility model is to provide a thin film protection structure for an electronic wristband.

[0004] To solve the above problems, this utility model provides a thin-film protective structure for an electronic bracelet. To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problems is as follows:

[0005] A thin-film protective structure for an electronic bracelet includes: a screen protector covering the screen of the electronic bracelet; and a packaging film, which is a heat-shrink film, which fully wraps the electronic bracelet after being heated and shrunk, with the screen protector located inside the packaging film; wherein the heat-shrinkable packaging film is a disc-shaped film, and the disc-shaped film has a cross-shaped easy-tear line at its axial end; one side of the screen protector has an outwardly protruding portion integrally formed, and the outwardly protruding portion does not contact the screen.

[0006] As a further improvement of this utility model, the inner wall of the disc-shaped film contacts the outer ring of the electronic bracelet, and the inner wall of the disc-shaped film does not contact the inner ring of the electronic bracelet; the cross-shaped easy-tear line includes two perpendicularly intersecting straight easy-tear lines, and the length of each straight easy-tear line is less than the diameter of the disc-shaped film.

[0007] As a further improvement of this utility model, the protruding part is in the shape of a doorway, which includes a semi-circular structure and a rectangular structure connected to the diameter end of the semi-circular structure, and the end of the rectangular structure away from the semi-circular structure is connected to the edge of the screen protector body.

[0008] As a further improvement of this utility model, the protruding part conforms to the outer ring of the wristband.

[0009] As a further improvement of this utility model, the shrinkage rate of the screen protector under specified heating conditions is less than that of the packaging film under the same heating conditions.

[0010] As a further improvement of this utility model, the light transmittance of the screen protector is greater than that of the packaging film.

[0011] As a further improvement of this utility model, the thickness of the packaging film is greater than the thickness of the screen protector.

[0012] As a further improvement of this utility model, the screen protector is made of PE material.

[0013] As a further improvement of this utility model, the packaging film is made of POF, PET, OPS or PVDC.

[0014] As a further improvement of this utility model, the thickness of the packaging film is one of 12μm, 15μm, 20μm, 25μm, 30μm, and 37μm.

[0015] The beneficial technical effects of the thin-film protective structure of the electronic bracelet of this application are:

[0016] A dual-layer film protection structure is provided, offering both partial and overall wrapping protection. The screen protector can specifically cover the electronic bracelet screen, preventing the screen from being exposed and damaged by friction. After the packaging film shrinks due to heat, it fully wraps the entire electronic bracelet, solving the problem of incomplete protection with only a single layer of heat-shrink film or a single film only covering the screen.

[0017] After being heated and shrunk, the packaging film takes the shape of a disc and has a cross-shaped easy-tear line at the axial end. Compared with the traditional design of a ring-shaped heat shrink film that is tightly attached to the wristband, the cross-shaped easy-tear line provides users with a clear and convenient tearing position, eliminating the need to search for the opening and greatly improving the convenience of removing the packaging. At the same time, the disc-shaped structure also avoids the problem of wrinkles caused by the shrinkage of the ring-shaped heat shrink film, which affects the appearance.

[0018] The screen protector is located inside the packaging film. The outer wrapping of the packaging film secures the screen protector, effectively preventing it from falling off during transportation and storage, and ensuring that the screen protector always maintains its protective function. The protruding part makes it easy for consumers to pinch and peel off the entire screen protector. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to specific embodiments:

[0025] To achieve the purpose of this utility model, please refer to Figures 1 to 3 A thin-film protective structure for an electronic bracelet includes: a screen protector 2 covering the screen 101 of the electronic bracelet 1; and a packaging film 3, which is a heat-shrink film that, after being heated and shrunk, completely wraps the electronic bracelet 1, with the screen protector 2 located inside the packaging film 3. The heat-shrinkable packaging film 3 forms a disc-shaped film, which has a hollow cavity to accommodate the electronic bracelet 1, and a cross-shaped easy-tear line 303 at its axial end. One side of the screen protector 2 has an outwardly protruding portion 202 integrally formed, which does not contact the screen 101.

[0026] The electronic bracelet includes a main body and a wristband 102. The main body has a screen 101 on the outer ring of the corresponding electronic bracelet. The packaging film 3 is a disc-shaped film, which consists of a side part 301 and two axial ends 302.

[0027] The dotted line is used to represent the cross-shaped easy-tear line 303, which has an alternating cutting effect on the packaging film 3.

[0028] Figure 3 It is a schematic diagram, that is, in Figure 1 Based on this, puncture the cross-shaped easy-tear line 303, which then becomes an opening 5. Further tear the opening 5 to remove the entire packaging film 3.

[0029] The beneficial effects of adopting the above technical solution are as follows: the packaging film 3 provides overall, full-coverage protection for the entire electronic bracelet 1, while the screen protector 2 specifically protects the screen 101. Furthermore, with the screen protector 2 inside and the packaging film 3 outside, the screen protector 2 is less likely to be knocked off. Moreover, the packaging film 3 is not a completely circular ring conforming to the shape of the electronic bracelet 1, but rather a disc shape. This provides a convenient location for the cross-shaped easy-tear line 303, which is suspended above the packaging film 3, making it easy for consumers to press and tear the cross-shaped easy-tear line 303 to access the electronic bracelet.

[0030] In some other embodiments of this invention, the inner wall of the disc-shaped film contacts the outer ring of the electronic bracelet 1, while the inner wall of the disc-shaped film does not contact the inner ring of the electronic bracelet 1. The cross-shaped easy-tear line 303 includes two perpendicularly intersecting straight easy-tear lines, the length of each straight easy-tear line being less than the diameter of the disc-shaped film.

[0031] like Figure 2 As shown, a through cavity 4 is formed in the middle of the electronic bracelet 1, which allows the wearer's wrist to pass through.

[0032] like Figure 1 and Figure 3 As shown, when a consumer purchases the electronic bracelet 1 and prepares to wear it, they first press the cross-shaped easy-tear line 303. Because the cross-shaped easy-tear line 303 damages part of the film structure, stress concentration occurs, and the cross-shaped easy-tear line 303 easily expands into the shape shown. Figure 3 The hole shown is 5.

[0033] The beneficial effects of adopting the above technical solution are: the inner wall of the disc-shaped film only contacts the outer ring of the electronic wristband 1, avoiding friction with the inner ring; the cross-shaped easy-tear line 303 is composed of two vertical short lines and its length is less than the diameter of the film, which makes it easy to tear and prevents accidental breakage, thus enhancing the ease of opening the packaging.

[0034] In some other embodiments of this utility model, the protruding part 202 is in the shape of a doorway, which includes a semi-circular structure and a rectangular structure connected to the diameter end of the semi-circular structure, and the end of the rectangular structure away from the semi-circular structure is connected to the edge of the screen protector 2 body.

[0035] The screen protector 2 includes a rectangular portion 201 and a protruding portion 202, with the rectangular portion 201 covering the screen 101.

[0036] The beneficial effects of adopting the above technical solution are: the protruding part 202 is designed as a doorway, which is smooth and makes it easy for users to pinch and peel off the screen protector 2, thus improving the convenience of operation and the overall appearance.

[0037] In some other embodiments of this utility model, the protrusion 202 conforms to the outer ring of the wristband 102.

[0038] The beneficial effects of adopting the above technical solution are: the protruding part 202 fits snugly on the outer ring of the wristband 102, keeping it stable and not shifting inside the packaging film 3, preventing it from falling off during transportation, and at the same time not affecting wearing comfort.

[0039] In some other embodiments of this utility model, the shrinkage rate of the screen protector 2 under specified heating conditions is less than that of the packaging film 3 under the same heating conditions.

[0040] The beneficial effects of adopting the above technical solution are: the shrinkage rate of the screen protector 2 under heat conditions is lower than that of the packaging film 3, ensuring that it will not deform and detach from the screen 101 during the heat shrinking process, thus maintaining effective protection for the screen.

[0041] In some other embodiments of this utility model, the light transmittance of the screen protector 2 is greater than that of the packaging film 3.

[0042] The beneficial effects of adopting the above technical solution are: the screen protector 2 has a high light transmittance, allowing users to clearly view the content of the screen 101 without removing the film, while the packaging film 3 has a low light transmittance and therefore no negative impact.

[0043] In some other embodiments of this utility model, the thickness of the packaging film 3 is greater than the thickness of the screen protector 2.

[0044] The beneficial effects of adopting the above technical solution are: the thickness of the packaging film 3 is greater than that of the screen protector 2, giving it better mechanical strength and wrapping properties, and effectively resisting external friction.

[0045] In some other embodiments of this utility model, the protective screen film 2 is made of PE material. PE is polyethylene material.

[0046] The advantages of adopting the above technical solution are: the PE material is relatively soft, with a slightly sticky and rough feel. It is easy to process and adhere, and there will be absolutely no adhesive residue after peeling it off from screen 101.

[0047] In some other embodiments of this utility model, the packaging film is made of POF, PET, OPS or PVDC.

[0048] The beneficial effects of adopting the above technical solutions are as follows: POF, PET, OPS, and PVDC are respectively polyolefin heat shrink film, polyethylene terephthalate heat shrink film, oriented polystyrene heat shrink film, and polyvinylidene chloride heat shrink film. POF has excellent comprehensive performance, combining high transparency, high toughness, and environmental friendliness; PET has extremely high transparency, rigidity, and printability; OPS is environmentally friendly and has excellent gloss and rigidity; and PVDC has good oxygen and moisture barrier properties.

[0049] In some other embodiments of this utility model, the thickness of the packaging film is one of 12μm, 15μm, 20μm, 25μm, 30μm, and 37μm.

[0050] The advantages of adopting the above technical solution are: limiting the thickness of the heat-shrinkable film to the range of 12 to 37 micrometers, balancing mechanical strength and heat-shrinkability. If it is too thin, it will be easily damaged; if it is too thick, the shrinkage force will be insufficient.

[0051] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They should not be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
