Description

TECHNICAL FIELD

[0001] The utility model relates to the field of mobile phone accessories, and specifically relates to a coupling hinge type protective shell for protecting the hinge of a folding screen mobile phone. BACKGROUND

[0002] In the use process of the folding screen mobile phone, the protection of its hinge is crucial. Currently, some magnetic type hinge protective shells have appeared on the market, aiming to protect the hinge of the folding screen mobile phone through the adsorption of magnets. However, such magnetic type hinge protective shells have many drawbacks.

[0003] Firstly, when installing the magnet, precise positioning and installation process are required, making installation difficult. A slight deviation in the installation position of the magnet can affect the magnetic attraction effect, and thus affect the protective effect of the protective shell on the hinge. Secondly, the entire assembly procedure is complex, requiring a large amount of labor and time cost. This not only increases the production difficulty, but also limits the improvement of production efficiency to some extent.

[0004] Furthermore, due to the limitations of technology and structural design, in order to ensure the magnetic attraction effect and overall strength, such protective shells often have a thick shell. For example, a kind of rotary shaft magnetic type full-cover hinge folding screen protective shell is disclosed in Chinese utility model patent 2021229195107. The thick shell not only increases the overall weight and volume of the mobile phone, affecting the user's holding feeling and carrying convenience, but also to some extent, covers up the design advantages of the folding screen mobile phone, such as being light and thin, and portable. In addition, the thick shell may also affect the heat dissipation performance of the mobile phone, which may have a potential impact on the normal operation of the mobile phone.

[0005] In summary, the existing magnetic type hinge protective shell has many shortcomings in actual application, and cannot meet the user's needs for folding screen mobile phone hinge protection in terms of convenient installation, low cost, and light and thin design. Therefore, it is of great practical significance to develop a folding screen mobile phone hinge protective shell that is easy to install, simple to assemble, low in cost, and light and thin.

Obviously, the described embodiments are only some embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0031] To make the technical solutions and advantages of the present application clearer, the embodiments of the present application will be described in further detail in the following with reference to the drawings.

[0032] Please refer to Figures 1-6 As shown in the figure, the present application provides a coupling hinge type protective shell, which comprises a protective shell 1, a hinge cover 2, and a coupler 3. The coupler 3 is provided with a first clamping groove 31 and a second clamping groove 32, and a groove 33 is arranged between the first clamping groove 31 and the second clamping groove 32. Magnets 4 that are magnetically attracted to each other are arranged in the first clamping groove 31 and the second clamping groove 32 respectively and close to the groove 33. The first clamping groove 31 and the second clamping groove 32 are fixed on the side edges of the protective shell 1 and the hinge cover 2 respectively. The hinge cover 2 automatically abuts against the hinge of the wrapped mobile phone through the coupler 3 and the magnets 4 inside the coupler 3.

[0033] In the present embodiment, the coupler 3 is made of silica gel and attached to the protective shell 1 and the hinge cover 2. The silica gel material has good flexibility and elasticity, realizes the resilience of the hinge cover 2, and has a longer service life. It should be noted that in other embodiments, other materials and other installation methods can be used, such as leather material, ultrasonic welding, and screw fixation.

[0034] As shown in Figure 4 , 6 The bottom of the coupler 3 extends to both sides to form a wing 34, and the wing 34 is fixedly installed with the protective shell 1 and the hinge cover 2. The arrangement of the wing 34 increases the contact area of the coupler 3 with the protective shell 1 and the hinge cover 2, further improves the stability of the connection, and makes the coupler 3 more secure during use.

[0035] In other embodiments, the top of the coupler 3 also extends to both sides to form a wing 34, and the wing 34 is fixedly installed with the protective shell 1 and the hinge cover 2, making the coupler 3 more secure during use.

[0036] The coupler 3 of the embodiment is arranged in sections, as shown in Figure 1 、 2 The side of the protective shell 1 and the hinge cover 2 is respectively provided with a first mounting position 11 and a second mounting position 21, and the first clamping groove 31 and the second clamping groove 32 of the coupler 3 are respectively wrapped and fixed on the first mounting position 11 and the second mounting position 21. The arrangement in sections can flexibly adjust the mounting position and the number of the coupler 3 according to actual needs, improve the versatility and applicability of the protective shell 1, and reduce the overall weight.

[0037] In some embodiments, the coupler 3 is in a long strip shape and extends from the bottom to the top of the hinge cover 2. The long strip-shaped coupler 3 can provide more comprehensive protection, so that the hinge cover 2 can closely fit the phone hinge in the entire length direction, thereby enhancing the protection effect. In some embodiments, the inner surface of the hinge cover 2 is provided with a buffer layer. The buffer layer can play a buffering role when the phone is subjected to impact, reduce the impact force on the hinge, and further protect the phone hinge.

[0038] In order to understand the disclosure of the utility model more thoroughly and comprehensively, the principle will be further explained in combination with the use mode.

The protective shell 1 is made of hard PC material and is a phone main body wrapping structure, and the left side is provided with a first mounting position 11. The right side of the hinge cover 2 is provided with a second mounting position 21. The coupler 3 is made of silica gel material and is a flexible short strip structure, which is arranged in sections between the hinge cover 2 and the protective shell 1.

[0040] The first clamping groove 31 and the second clamping groove 32 are symmetrically arranged inside the coupler 3, and a groove 33 is formed between the two clamping grooves to facilitate rotation. Neodymium iron boron magnets are installed on the inner wall of the clamping groove close to the groove 33, and the two magnets are oppositely arranged with different magnetic poles. The first clamping groove 31 of the coupler 3 is wrapped and clamped on the first mounting position 11 of the protective shell 1, and the second clamping groove 32 is wrapped and clamped on the second mounting position 21 of the hinge cover 2.

[0041] In actual use, the coupler 3 made of silica gel will automatically rebound, and when the angle of the hinge cover 2 and the protective shell 1 approaches 90 degrees, the magnetic field force generated by the magnet 4 in the coupler 3 will automatically guide the hinge cover 2 to accurately wrap the phone hinge.
