Description

Technical Field

[0001] This utility model relates to the field of electronic device accessories technology, and in particular to an automatic adsorption structure for the hinge cover of a foldable screen mobile phone protective case. Background Technology

[0002] Traditional foldable screen protection kits have three major drawbacks: ① The protective case adopts a split structure of upper and lower cover, which only protects the upper and lower split screens of the foldable screen. There is no protective kit for the hinge between the split screens, so it is not protected. ② The structure with rotating shaft protection uses a spring mechanism to support the shell. This protection method requires a large structural space and is not aesthetically pleasing. ③ The hinge is protected by using a sliding connector. The sliding connector slides out and protects the hinge by folding the screen. However, after long-term use, the sliding groove of the sliding connector is prone to wear and jamming, and the probability of extension failure is high. Utility Model Content

[0003] This utility model provides an automatic adsorption structure for the hinge cover of a foldable screen mobile phone protective case, aiming to solve the contradiction between dynamic hinge protection and the overall thinness and lightness of the device.

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0017] like Figs. 1 to 4As shown, the present invention discloses an automatic adsorption structure for a folding screen mobile phone protective case hinge cover, comprising a shell body 1, a hinge cover 2, and an elastic connecting piece 3. The elastic connecting piece 3 is provided with a shell connecting section 31 and a cover connecting section 32. In the absence of force, the cover connecting section 32 is inclined at an acute angle toward the shell connecting section 31. The shell connecting section is connected to the shell body 1, and the cover connecting section 32 is connected to the hinge cover 2. The hinge cover 2 rotates along the edge of the shell body 1 through the elastic connecting piece 3.

[0018] By molding the elastic connecting piece 3, the TPU material itself is used to injection mold the elastic connecting piece 3 into an acute-angled shape, so that the elastic connecting piece 3 generates a rebound lateral force when moving towards the main body 1 of the shell. During the opening and closing of the hinge cover 2, the acute-angled part of the elastic connecting piece 3 can unfold to 180°; when the folding phone is closed, the hinge cover 2 returns to the acute-angled shape under the rebound force of the elastic connecting piece 3, realizing the automatic rebound function.

[0019] The elastic connecting piece 3 also has a bending section 33. The two sides of the bending section 33 are connected to the shell connecting section 31 and the cover connecting section 32, respectively. The connection between the bending section 33 and the shell connecting section 31 has an inward bending line 34, and the connection between the bending section 33 and the cover connecting section 32 has an outward bending line 35. The inward bending structure formed by the bending section 33 and the shell connecting section provides a rebound force in a reverse bow shape. When the folding force is removed, the inward bending structure helps the elastic connecting piece 3 return to its acute angle state. The outward bending structure formed by the bending section 33 and the cover connecting section 32 provides a support point for the pivot cover 2 to bend outward to 180° when it is opened and closed relative to the shell body 1, reducing the impact on the rebound structure of the elastic connecting piece 3 when bending outward.

[0020] The elastic connecting piece 3 is made of high-hardness TPU plastic. The elastic connecting piece 3 is injection molded from high-hardness TPU, and its angle is designed to be an acute angle. Thus, when it is assembled onto the main body 1 and the pivot cover 2, the pivot cover 2 will fit tightly against the main body 1 under the angular stress of the elastic connecting piece 3, thereby achieving an interference fit design.

[0021] The main body of the housing 1 has a connecting piece mounting groove 11, and the housing connecting section 31 is fixed in the connecting piece mounting groove 11. The housing connecting section 31 is bonded to the connecting piece mounting groove 11 by hot melt adhesive film. The main body of the housing 1 adopts Kevlar molding process, and its appearance texture is consistent with the surface texture of the pivot cover 2. The inner side has a connecting piece mounting groove 11, which serves as the bonding groove for the elastic connecting piece 3. The elastic connecting piece 3 is assembled and bonded by hot melt adhesive film.

[0022] The hinge cover 2 has a edging 21, which is fitted onto and fixedly connected to the elastic connecting piece 3. The edging 21 is bonded to the elastic connecting piece 3 with hot melt adhesive film. The hinge cover 2 is manufactured using Kevlar molding technology, and its appearance texture is consistent with the texture of the shell body 1. The edging 21 is designed internally as an adhesive groove for the elastic connecting piece 3, and the elastic connecting piece 3 is assembled and bonded with hot melt adhesive film.

[0023] The automatic adsorption structure of the hinge cover of the foldable screen phone case also includes a magnet component 4. The hinge cover 2 has a magnet slot 22, and the magnet component 4 is installed within the magnet slot 22, positioned between the hinge cover 2 and the elastic connecting piece 3. Through the design of the molding angle of the elastic connecting piece 3, and utilizing the toughness and resilience of the TPU material, the hinge cover 2 achieves its spring-loaded function. The hinge cover 2 has a magnet slot 22 inside, and the built-in magnet component 4 adsorbs the hinge of the actual phone, ensuring a tight fit after alignment. The magnet component 4 can be a magnetic structure composed of multiple positive and negative magnets arranged sequentially.

[0024] The gap between the hinge cover 2 and the main body 1 is less than 0.5mm. Both the main body 1 and the hinge cover 2 are made of Kevlar material, whose unique woven texture adds a distinctive aesthetic to the product. Combined with the lightweight body design, the thickness of the main body 1 is only 0.8mm, reducing space occupation by 40%, and the folded thickness is ≤4.5mm, solving the problem of bulky traditional structures and bringing users a fresh and natural technological experience.

[0025] No manual adjustment is required; the device adapts to the phone's shape using magnetic attraction and bending deformation. The gap between the hinge cover 2 and the main body 1 is less than 0.5mm, and they are connected and assembled using elastic connecting pieces 3, thus more effectively protecting the hinge of the actual device and completely solving the problems of loose connecting strips and dust ingress in traditional systems.

[0026] In this foldable phone case's hinge cover automatic adsorption structure, the main body 1 and the hinge cover 2 are connected by a hot melt adhesive film bonded to an elastic connecting piece 3. The hinge cover 2 can rotate along the edge of the main body 1, thus switching from an unfolded state (horizontally parallel) to a folded state (facing each other). Under the rebound force of the elastic connecting piece 3, the hinge cover 2 automatically resets and is adsorbed to the outside of the phone's hinge by the magnetic assembly 4, achieving a tight fit.

[0027] The automatic adsorption structure of the hinge cover for the foldable screen phone case of this invention has the following characteristics: 1) This structure is not only aesthetically pleasing but also has an ID function, which can be perfectly integrated with phone cases and electronic devices, thus greatly facilitating user use.

[0028] 2) The folding screen protective case of the present invention consists of a shell body 1, an elastic connecting piece 3 made of TPU material, a Kevlar hinge cover 2, and a magnet assembly 4. The components are firmly connected by hot melt adhesive film.

[0029] 3) The main body 1 and the hinge cover 2 are tightly connected by the elastic connecting piece 3. The gap between them is small, which significantly enhances the three-dimensional effect of the Kevlar texture and improves the overall visual effect of the electronic device, making it more fashionable and high-end.

[0030] 4) Kevlar hinge cover 2 can effectively protect the hinge part of foldable screen phones, prevent dust accumulation, liquid seepage and physical scratches, thereby avoiding damage to the screen hinge area.

[0031] 5) The hinge cover 2 and the main body of the shell are designed with an automatic spring-back structure, so that the hinge cover 2 can automatically return to its original position during the unfolding and closing of the foldable screen phone, thereby providing effective protection.

[0032] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
