Description

TECHNICAL FIELD

[0002] Mobile terminals such as tablets and smartphones play an increasingly important role in people's daily life. In order to protect these devices from damage, users often choose to equip them with protection clips or protective cases. The hinge of the protection clip, as a key component connecting the various parts of the protection clip, its performance and stability are crucial to the overall user experience of the protection clip. Traditional mobile terminal protection clip hinges mostly use simple hinges or slide rail structures. These structures can meet the basic opening and closing requirements to some extent, but they have many shortcomings in the long-term use process.

[0003] For example, the "protection clip hinge" disclosed in Chinese invention patent (application number: CN202210031283.0) has the following disclosure in the specification: When a mobile terminal device is in use, a protective case or a protection clip is usually added to the terminal device to protect it and prolong its service life. When setting the protective case or the protection clip, two shaft-connected rubber plates are usually used to protect the top and bottom surfaces of the mobile terminal. The shaft connecting piece is generally made of a hinge. The protective case or the protection clip combined with the hinge rubber plate generally has serious wear and damage after being opened and closed for a period of time, causing the two rubber plates to separate, affecting the use of the terminal device protective case, and the protective case or the protection clip combined with the hinge rubber plate has a single function, which can only be used as a movable part to combine two components into one. The shaft connecting piece assembly steps are complicated, the use range is narrow, and the protection clip is prone to damage due to over-expansion of the two rubber plates, the hinge is prone to breakage, and the overall durability of the protection clip or the protective case is poor.

[0051] In the embodiment 2, the rotating shaft of the mobile terminal protection clip provided in the embodiment 1 is further optimized, specifically, as shown in the figure, Figures 3-9 The connecting part of the butt joint shaft 201 and the hinged shaft 202 is provided with a support piece 3, the support piece 3 comprises a limiting plate 301 and a support spring 302, four hinged grooves 303 are equiangularly arranged in the middle of the butt joint shaft 201, one end of the limiting plate 301 is movably hinged in the hinged groove 303, the other end of the limiting plate 301 is fixedly connected to the top of the support spring 302, the bottom of the support spring 302 is fixedly connected to the bottom of the inner cavity of the hinged groove 303, the inner cavities of the left side auxiliary rotor mechanism 103 and the right side auxiliary rotor mechanism 105 are both fixedly installed with butt joint pipes 205, a plurality of fixed grooves 206 are circumferentially arranged on the inner wall of the butt joint pipe 205, the fixed grooves 206 are located on the outer side of the hinged groove 303, the top end of the limiting plate 301 is clamped in the fixed groove 206, the limiting plate 301 is in the shape of a slope, the protruding end of the limiting plate 301 is attached to the inner cavity top of the fixed groove 206, the hinged end of the limiting plate 301 is tangent to the inner surface of the butt joint pipe 205, the inner ends of the two butt joint shafts 201 are both fixedly installed with fixed rings 304, the outer sides of the two fixed rings 304 are both fixedly connected with extrusion springs 305, the other ends of the two extrusion springs 305 are respectively fixedly connected to the inner walls of the left side auxiliary rotor mechanism 103 and the right side auxiliary rotor mechanism 105, the two sides of the inner cavity of the installation slot 109 are both slidably clamped with pressing plates 307, the inner sides of the pressing plates 307 are fixedly connected with positioning springs 306, the other ends of the positioning springs 306 are fixedly connected to the inner walls of the installation slot 109, the middle part of the installation slot 109 is slidably clamped with an extrusion block 308, the inner end of the extrusion block 308 is fixedly connected with a return spring 309, the inner end of the return spring 309 is fixedly connected to the inner wall of the installation slot 109 to support the extrusion block 308 outward, the two sides of the extrusion block 308 are both inwardly recessed arc surfaces, two pull buckles 203 are respectively located on the two sides of the extrusion block 308, the opposite surfaces of the two pull buckles 203 are adapted to the recessed arc surfaces on the two sides of the extrusion block 308, the recessed arc surfaces of the extrusion block 308 are magnetic, the arc surface material of the pull buckle 203 adapted to the extrusion block 308 is iron.

[0052] The support of the limit plate 301 by the support spring 302 can make the limit plate 301 always engaged with the inside of the fixing groove 206, so that the left auxiliary rotor mechanism 103 will not rotate relative to the main rotor mechanism 101. At this time, if the left auxiliary rotor mechanism 103 and the right auxiliary rotor mechanism 105 need to be rotated, it is only necessary to move the docking shaft 201 so that the limit plate 301 is squeezed by the docking tube 205, and the limit plate 301 will retract into the inside of the docking shaft 201, thereby disengaging the limit plate 301 from the inside of the fixing groove 206. At this time, the left auxiliary rotor mechanism 103 and the right auxiliary rotor mechanism 105 can be rotated. The right auxiliary rotor mechanism 105 rotates, and in this way, the electronic device can be protected, especially when the electronic device is placed in a backpack, the internal situation cannot be observed, and when the protective clip is opened due to external forces such as gravity, some hard objects are likely to enter it, thereby being clamped on the screen and keyboard of the electronic device, and then being squeezed will cause damage to the electronic device. Therefore, when the electronic device is placed in the bag, it can play a good protective role for the electronic device.

When the hinge shaft 202 needs to be expanded outward, the pressure plate 307 only needs to be pressed inward so that the hinge shaft 202 can be automatically opened under the action of the torsion spring. At this time, the pressure plate 307 is squeezed inward by the hinge shaft 202. When it needs to be retracted, the hinge shaft 202 is manually pressed into the inside of the mounting groove 109. The pressure plate 307 will automatically reset under the action of the positioning spring 306 to limit the hinge shaft 202 again.

[0053] Through the cooperation of the support 3 and the connecting piece 2, after the electronic product is unfolded, the left side auxiliary rotor mechanism 103 and the right side auxiliary rotor mechanism 105 are limited and fixed by the support 3, so that the electronic product is stable after being unfolded, and in this way, the traditional friction mode is replaced to prevent the damage of the rotating shaft in the process of multiple and long time use, the service life of the rotating shaft is improved, when the electronic product is closed, the hinge is fixed by the support 3, the protective cover cannot be opened when it is not unlocked, so that when the electronic product is put into the bag, the protective cover cannot be opened under the action of external force, and some sundries cannot fall into the inside of the protective cover, so that the sundries cannot be clamped on the screen of the electronic product and then be pressed to damage the screen of the electronic product, the protection effect of the electronic product is realized, and the problem that the screen or the operation keyboard of the electronic product is damaged by the sundries in the prior art is solved.

[0056] The support of the limiting plate 301 by the support spring 302 can make the limiting plate 301 always engage in the inside of the fixed groove 206, thereby making the left side auxiliary rotor mechanism 103 not rotate relative to the main rotor mechanism 101, at this time, if the left side auxiliary rotor mechanism 103 and the right side auxiliary rotor mechanism 105 need to be rotated, only the abutting shaft 201 needs to be moved, so that the limiting plate 301 is extruded by the abutting pipe 205, the limiting plate 301 will be retracted into the inside of the abutting shaft 201, so that the limiting plate 301 is separated from the inside of the fixed groove 206, at this time, the left side auxiliary rotor mechanism 103 and the right side auxiliary rotor mechanism 105 can be rotated, and the electronic device can be protected by this way, especially when the electronic device is put into the backpack, the inside situation cannot be observed, when the protection clip is opened due to gravity or other external force, some hard objects are easy to enter, thereby clamping the screen and keyboard of the electronic device, and then being extruded will cause damage to the electronic device, therefore, when the electronic device is put into the bag, the electronic device can be well protected;

[0057] When the two abutting shafts 201 are extruded to the middle by pressing the two pullers 203 or the buttons 204 at both ends, the limiting plate 301 will be extruded by the inner wall of the abutting pipe 205, the puller 203 will be adsorbed to the two sides of the extrusion block 308, thereby making the limiting plate 301 separate from the inside of the fixed groove 206, at this time, the angle of the electronic device and the protection clip can be adjusted, then when the angle is fixed, the puller 203 can be separated to the two sides by pressing the extrusion block 308, at this time, the puller 203 is separated from the magnetic attraction surface of the extrusion block 308, the abutting shaft 201 will automatically reset under the support of the extrusion spring 305, thereby making the limiting plate 301 engage in the fixed groove 206 in the inner wall of the abutting pipe 205 again, thereby fixing the protection clip, this way can have a good fixing effect, and prevent the rotating shaft from being damaged due to wear after long time use, a pair of pressure plates 307 are arranged outside the main rotor mechanism 101 and are always clamped on the outer side of the hinge shaft 202 by the positioning spring 306, thereby limiting the hinge shaft 202, when the hinge shaft 202 needs to be unfolded to the outside, only the pressure plate 307 needs to be pressed to the inside, thereby making the hinge shaft 202 automatically open under the action of the torsion spring, at this time, the pressure plate 307 is extruded to the inside by the hinge shaft 202, when it needs to be retracted, the hinge shaft 202 is manually pressed into the installation groove 109, the pressure plate 307 will automatically reset to limit the hinge shaft 202 again under the action of the positioning spring 306.
