Description

Technical Field

[0001] The present invention relates to the field of pivot connections, and more particularly, to a rotating shaft of a protective clip for a mobile terminal. Background Art

[0002] Mobile terminals such as tablet computers and smartphones play an increasingly important role in people's daily lives. To protect these devices from damage, users usually choose to equip them with protective clips or covers. Among them, the rotating shaft of the protective clip, as a key component connecting various parts of the protective clip, its performance and stability are crucial for the use experience of the entire protective clip. Traditional rotating shafts of mobile terminal protective clips mostly use simple hinge or slide rail structures. Although these structures can meet the basic opening and closing requirements to a certain extent, there are many deficiencies in the long-term use process.

[0003] For example: "A Rotating Shaft of a Protective Clip" disclosed in the Chinese invention patent (application number: CN202210031283.0), its specification discloses that when using a mobile terminal device, a protective cover or clip is usually added to the terminal device to protect the terminal device and extend its service life; when setting the protective cover or clip, two axially connected rubber plates are usually used to protect the top and bottom surfaces of the mobile terminal respectively, and its axially connected parts generally use hinges. For the protective cover or clip combined with the hinge rubber plate, generally after the rubber plate is opened and closed for a period of time, the hinge will be severely worn and damaged and broken, so that the two rubber plates will separate, affecting the use of the protective cover of the terminal device. At the same time, the protective cover or clip combined with the hinge rubber plate has a single function and can only be used as a movable part to combine two components into one. Its axially connected part assembly steps are cumbersome, the use range is narrow, and it is easy to have the problem that the two rubber plates are unfolded excessively, resulting in damage to the protective clip and breakage of the hinge, and the overall durability of the protective clip or cover is poor; the above patent can prove the defects existing in the prior art.

[0004] Therefore, we make improvements in this regard and propose a rotating shaft of a mobile terminal protective clip. Summary of the Invention

[0005] The purpose of the present invention is to address the problems that the protective cover or clip combined with the hinge rubber plate has a single function and can only be used as a movable part to combine two components into one, and its axially connected part assembly steps are cumbersome and the use range is narrow.

[0006] To achieve the above-mentioned invention purpose, the present invention provides a rotating shaft of a mobile terminal protective clip to improve the above problems.

[0007] Specifically, this application is as follows:

[0008] The rotating shaft of the mobile terminal protection clip includes a rotating shaft mechanism. The rotating shaft mechanism comprises a main rotor mechanism, a left-side auxiliary rotor mechanism and a right-side auxiliary rotor mechanism that are rotatably installed on both sides of the main rotor mechanism. An installation groove is formed in the middle of the main rotor mechanism, and a connecting piece is arranged in the middle of the installation groove.

[0009] The connecting piece includes a docking shaft and a hinge shaft. The docking shaft is sleeved in the middle of the main rotor mechanism and extends out from both ends of the main rotor mechanism. The left-side auxiliary rotor mechanism and the right-side auxiliary rotor mechanism are respectively rotatably sleeved on both ends of the main rotor mechanism and rotatably sleeved on the docking shaft. Buttons are threadedly connected to the outer ends of both docking shafts, and the two buttons are respectively movably sleeved on the outer ends of the left-side auxiliary rotor mechanism and the right-side auxiliary rotor mechanism.

[0011] As a preferred technical solution of the present application, a support piece is arranged at the connection between the docking shaft and the hinge shaft. The support piece includes a limiting plate and a support spring. Four hinge grooves are equiangularly formed in the middle of the docking shaft. One end of the limiting plate is movably hinged inside the hinge groove, the other end of the limiting plate is fixedly connected to the top of the support spring, and the bottom of the support spring is fixedly connected to the inner cavity bottom of the hinge groove.

[0012] As a preferred technical solution of the present application, docking pipes are fixedly installed in the middle of the inner cavities of the left-side auxiliary rotor mechanism and the right-side auxiliary rotor mechanism. Fixing grooves are circumferentially arranged on the inner wall of the docking pipe, and the fixing grooves are located outside the hinge grooves. The top end of the limiting plate is clamped inside the fixing groove.

[0013] As a preferred technical solution of the present application, the limiting plate is in a slope shape, the protruding end of the limiting plate fits to the inner cavity top of the fixing groove, and the hinged end of the limiting plate is tangent to the inner surface of the docking pipe.

[0014] As a preferred technical solution of the present application, fixing rings are fixedly installed at the inner ends of both docking shafts, and extrusion springs are fixedly connected to the outer sides of both fixing rings. The other ends of the two extrusion springs are respectively fixedly connected to the inner walls of the left-side auxiliary rotor mechanism and the right-side auxiliary rotor mechanism.

[0015] As a preferred technical solution of the present application, pressing plates are slidably clamped on both sides of the inner cavity of the installation groove. A positioning spring is fixedly connected to the inner side of the pressing plate, and the other end of the positioning spring is fixedly connected to the inner wall of the installation groove.

[0016] As a preferred technical solution of the present application, an extrusion block is slidably clamped in the middle of the installation groove. The inner end of the extrusion block is fixedly connected with a return spring, and the inner end of the return spring is fixedly connected to the inner wall of the installation groove to support the extrusion block outward.

[0017] As a preferred technical solution of the present application, both sides of the extrusion block are arc surfaces recessed inward. The two buckles are respectively located on both sides of the extrusion block. The opposite surfaces of the two buckles are adapted to the arc surfaces recessed on both sides of the extrusion block. The recessed arc surface of the extrusion block is magnetic, and the material of the arc surface of the buckle adapted to the extrusion block is iron.

[0018] As a preferred technical solution of the present application, an intermediate fixing plate is fixedly installed on the bottom side of the main rotor mechanism, a left fixing plate is fixedly installed on the top side of the left auxiliary rotor mechanism, a right fixing plate is fixedly installed on the top side of the right auxiliary rotor mechanism, a top cover is fixedly installed at the bottom of the left fixing plate and the right fixing plate, and a bottom plate is fixedly installed on the top of the intermediate fixing plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] In the solution of the present application:

[0021] 1. To solve the problems of cumbersome assembly steps and narrow application range of the shaft connector in the prior art, the present application quickly connects the rotating shaft mechanism through the provided connector. After bending the docking shaft and the hinge shaft, they are inserted into the inside of the main rotor mechanism, and the outer end of the docking shaft extends out from both ends of the main rotor mechanism. Then, the left auxiliary rotor mechanism and the right auxiliary rotor mechanism are respectively rotatably connected to both ends of the main rotor mechanism, so that the docking shaft is rotatably sleeved in the middle of the left auxiliary rotor mechanism and the right auxiliary rotor mechanism. Then, a button is threadedly connected to the outer end of the docking shaft, so as to fix the left auxiliary rotor mechanism and the right auxiliary rotor mechanism to both ends of the main rotor mechanism. Thus, the connection shaft can be assembled quickly and conveniently. At the same time, after the assembly of the connector is completed, by bending the hinge shaft outward, it can support the protective clip, realizing not only the quick assembly of the connection shaft, but also the transformation of the structure so that the connector can be used as a support structure, and further making the electronic product more stable after unfolding;

[0022] 2. To solve the problem that in the prior art, the rotating shaft is fixed after the electronic product is unfolded through the action of damping or friction, but long-term use may cause the friction effect of the rotating shaft to weaken or the damping effect to decrease. In this application, the support member and the connecting member are arranged to cooperate with each other. After the electronic product is unfolded, the left and right auxiliary rotor mechanisms are limited and fixed by the support member, so that the electronic product is stable after unfolding. In this way, the traditional friction method is replaced to prevent the damage of the rotating shaft during multiple and long-term use, and the effect of improving the service life of the rotating shaft is achieved;

[0023] 3. When the electronic product is closed, the hinge is fixed by the support member arranged. When it is not unlocked, the protective cover cannot be opened, so as to prevent some sundries from falling into the inside of the protective cover when the electronic product is put into a bag and the protective cover is opened under the action of external force, and then the sundries are clamped to the screen of the electronic product and then crushed the screen of the electronic product when being squeezed again, realizing the protection effect on the electronic product and solving the problem that the screen or the operation keyboard of the electronic product is crushed by sundries when the electronic product is put into a bag in the prior art.

[0045] The rotating shaft of the mobile terminal protection clip provided by the present invention quickly connects the rotating shaft mechanism 1 through the provided connecting member 2. After bending the docking shaft 201 and the hinge shaft 202, they are inserted into the inner side of the main rotor mechanism 101, and the outer ends of the docking shaft 201 extend from both ends of the main rotor mechanism 101. The left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105 are respectively rotatably connected to both ends of the main rotor mechanism 101, so that the docking shaft 201 is rotatably sleeved in the middle of the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105. Then, button 204 is threadedly connected to the outer end of the docking shaft 201, so that the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105 are fixed to both ends of the main rotor mechanism 101. Furthermore, the connecting shaft can be assembled quickly and conveniently.

[0046] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings.

[0047] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0048] It should be noted that like reference numerals and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0049] Example 1, please refer to Figures 1 - 3 , a rotating shaft of a mobile terminal protection clip, which includes a rotating shaft mechanism 1. The rotating shaft mechanism 1 includes a main rotor mechanism 101 and a left-side auxiliary rotor mechanism 103 and a right-side auxiliary rotor mechanism 105 rotatably installed on both sides of the main rotor mechanism 101. An installation groove 109 is formed in the middle of the main rotor mechanism 101. A connecting member 2 is provided in the middle of the installation groove 109. A middle fixing plate 102 is fixedly installed on the bottom side of the main rotor mechanism 101. A left fixing plate 104 is fixedly installed on the top side of the left-side auxiliary rotor mechanism 103. A right fixing plate 106 is fixedly installed on the top side of the right-side auxiliary rotor mechanism 105. A top cover 107 is fixedly installed at the bottoms of the left fixing plate 104 and the right fixing plate 106. A bottom plate 108 is fixedly installed on the top of the middle fixing plate 102. The connecting member 2 includes a docking shaft 201 and a hinge shaft 202. The docking shaft 201 is sleeved in the middle of the main rotor mechanism 101 and extends from both ends of the main rotor mechanism 101. The left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105 are respectively rotatably sleeved on both ends of the main rotor mechanism 101 and rotatably sleeved on the docking shaft 201. Button 204 is threadedly connected to the outer ends of both docking shafts 201. The two buttons 204 are respectively movably sleeved on the outer ends of the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105. The inner end of the docking shaft 201 is movably hinged to the hinge shaft 202 through a torsion spring. The hinge shaft 202 can be bent outward. An expansion rod 207 is threadedly connected inside the hinge shaft 202. The outer end of the expansion rod 207 is fixedly connected to a pull buckle 203. After pulling out the hinge shaft 202 by bending it from the middle, by rotating the expansion rod 207 to extend it, the stability of the protection clip can be further increased. The pull buckle 203 is located at the outer end of the hinge shaft 202. A middle fixing plate 102 is fixedly installed on the bottom side of the main rotor mechanism 101. A left fixing plate 104 is fixedly installed on the top side of the left-side auxiliary rotor mechanism 103. A right fixing plate 106 is fixedly installed on the top side of the right-side auxiliary rotor mechanism 105. A top cover 107 is fixedly installed at the bottoms of the left fixing plate 104 and the right fixing plate 106. A bottom plate 108 is fixedly installed on the top of the middle fixing plate 102;

[0050] After bending the docking shaft 201 and the hinge shaft 202, place the docking shaft 201 in the middle of the installation groove 109 and push it outward. The docking shaft 201 extends from the side of the installation groove 109. Then, respectively sleeved the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105 on both sides of the main rotor mechanism 101 and sleeve the docking shaft 201 in the middle. Then, thread the button 204 to the outer end of the docking shaft 201 to limit the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105, so that the rotating shaft can be quickly assembled. After the assembly is completed, at this time, by bending the hinge shaft 202 toward the middle, the protective clip can be supported during use, making the supporting area larger, and further playing a better stabilizing role for the electronic device.

[0051] Embodiment 2 further optimizes the rotating shaft of the mobile terminal protective clip provided in Embodiment 1. Specifically, as Figures 3 - 9 shown, a support member 3 is provided at the connection of the docking shaft 201 and the hinge shaft 202. The support member 3 includes a limit plate 301 and a support spring 302. Four hinge grooves 303 are equiangularly opened in the middle of the docking shaft 201. One end of the limit plate 301 is movably hinged inside the hinge groove 303. The other end of the limit 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 inner cavity bottom of the hinge groove 303. Docking pipes 205 are fixedly installed in the middle of the inner cavities of the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105. Fixed grooves 206 are circumferentially arranged on the inner wall of the docking pipe 205. The fixed grooves 206 are located outside the hinge grooves 303. The top end of the limit plate 301 is engaged inside the fixed groove 206. The limit plate 301 is in a slope shape. The protruding end of the limit plate 301 fits to the top of the inner cavity of the fixed groove 206. The hinged end of the limit plate 301 is tangent to the inner surface of the docking pipe 205. Fixed rings 304 are fixedly installed at the inner ends of the two docking shafts 201. Extrusion springs 305 are fixedly connected to the outer sides of the two fixed rings 304. 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. Pressure plates 307 are slidably clamped on both sides of the inner cavity of the installation groove 109. A positioning spring 306 is fixedly connected to the inner side of the pressure plate 307. The other end of the positioning spring 306 is fixedly connected to the inner wall of the installation groove 109. An extrusion block 308 is slidably clamped in the middle of the installation groove 109. The inner end of the extrusion block 308 is fixedly connected to a return spring 309. The inner end of the return spring 309 is fixedly connected to the inner wall of the installation groove 109 to support the extrusion block 308 outward. Both sides of the extrusion block 308 are arc surfaces sunken inward. Two pull buttons 203 are respectively located on both sides of the extrusion block 308. The opposite surfaces of the two pull buttons 203 are adapted to the sunken arc surfaces on both sides of the extrusion block 308. The sunken arc surface of the extrusion block 308 has magnetism. The arc surface material of the pull button 203 adapted to the extrusion block 308 is iron;

[0052] The support of the limiting plate 301 by the support spring 302 can keep the limiting plate 301 always engaged inside the fixing groove 206, so that the left-side auxiliary rotor mechanism 103 will not rotate relative to the main rotor mechanism 101. At this time, if it is necessary to rotate the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105, only by moving the docking shaft 201, the limiting plate 301 will be squeezed by the docking pipe 205, and the limiting plate 301 will retract into the inside of the docking shaft 201, so that the limiting plate 301 disengages from the inside of the fixing groove 206. At this time, the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105 can be rotated. By this method, the electronic device can be protected. Especially when the electronic device is placed in a backpack, the internal situation cannot be observed. When the protective clip is opened due to external forces such as gravity, it is easy for some hard objects to enter, thus clamping the screen and keyboard of the electronic device. 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 two buckles 203 or the buttons 204 at both ends are pressed to squeeze the two docking shafts 201 towards the middle, the buckles 203 will adsorb on both sides of the extrusion block 308. At this time, the limiting plate 301 will be squeezed by the inner wall of the docking pipe 205, so that the limiting plate 301 disengages from the inside of the fixing groove 206. At this time, the angle between the electronic device and the protective clip can be adjusted. Then, when fixing the angle, the buckles 203 can be separated to both sides by pressing the extrusion block 308, so that the limiting plate 301 is inserted into the fixing groove 206 opened on the inner wall of the docking pipe 205 again, thereby fixing the protective clip. This method can play a good fixing role and prevent the rotating shaft from being damaged due to wear after long-term use. A pair of pressing plates 307 are arranged on the outer side of the main rotor mechanism 101 and are supported by the positioning spring 306 to always keep outward engagement on the outer side of the hinge shaft 202 to limit the hinge shaft 202. When it is necessary to expand the hinge shaft 202 outward, only by pressing the pressing plate 307 inward, the hinge shaft 202 will automatically open under the action of the torsion spring. At this time, the pressing plate 307 is squeezed inside by the hinge shaft 202. When it is necessary to retract, manually press the hinge shaft 202 into the installation groove 109, and the pressing 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 provided support member 3 and the connecting member 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 member 3, so that the electronic product is stable after being unfolded. In this way, the traditional friction method is replaced to prevent the damage of the rotating shaft during multiple and long-term use, achieving the effect of improving the service life of the rotating shaft. When the electronic product is closed, the support member 3 fixes the hinge. When it is not unlocked, the protective cover cannot be opened, preventing sundries from falling into the inside of the protective cover when the electronic product is put into a bag under the action of external force. When the sundries are clamped on the screen of the electronic product and then squeezed again, the screen of the electronic product will be damaged, realizing the protection of the electronic product and solving the problem that the screen or the operation keyboard of the electronic product is damaged by sundries when it is put into a bag in the prior art.

[0054] The use process of the rotating shaft of the mobile terminal protection clip provided by the present invention is as follows:

[0055] After bending the docking shaft 201 and the hinge shaft 202, the docking shaft 201 is placed in the middle of the installation groove 109 and pushed outward, and the docking shaft 201 extends out from the side of the installation groove 109. Then, the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105 are respectively sleeved on both sides of the main rotor mechanism 101, and the docking shaft 201 is sleeved in the middle. Then, the button 204 is threadedly connected to the outer end of the docking shaft 201 to limit the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105, so that the rotating shaft can be quickly assembled. After the assembly is completed, at this time, by bending the hinge shaft 202 toward the middle, the protective clip can be supported during use, the supporting area is larger, and thus a better stabilizing effect is achieved on the electronic device;

[0056] The support of the limiting plate 301 by the support spring 302 enables the limiting plate 301 to always be engaged inside the fixing groove 206, so that the left-side auxiliary rotor mechanism 103 will not rotate relative to the main rotor mechanism 101. At this time, if it is necessary to rotate the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105, only by moving the docking shaft 201 can the limiting plate 301 be squeezed by the docking pipe 205, and the limiting plate 301 will retract into the docking shaft 201, so that the limiting plate 301 disengages from the inside of the fixing groove 206. At this time, the left-side auxiliary rotor mechanism 103 and the right-side auxiliary rotor mechanism 105 can be rotated. This method can protect the electronic device. Especially when the electronic device is placed in a backpack, the internal situation cannot be observed. When the protective clip opens due to external forces such as gravity, it is easy for some hard objects to enter, thus clamping 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;

[0057] When the two docking shafts 201 are squeezed towards the middle by pressing the two buckles 203 or the buttons 204 at both ends, the limiting plate 301 will be squeezed by the inner wall of the docking pipe 205, and the buckles 203 will be adsorbed on both sides of the extrusion block 308, so that the limiting plate 301 disengages from the inside of the fixing groove 206. At this time, the angle between the electronic device and the protective clip can be adjusted. Then, when fixing the angle, the buckles 203 can be separated to both sides by pressing the extrusion block 308. At this time, the magnetic adsorption surface of the buckle 203 and the extrusion block 308 is disengaged, and the docking shaft 201 will automatically reset under the support of the extrusion spring 305, so that the limiting plate 301 is inserted into the fixing groove 206 opened on the inner wall of the docking pipe 205 again, thereby fixing the protective clip. This method can play a good fixing role and prevent the rotating shaft from being damaged due to wear after long-term use. A pair of pressing plates 307 are provided outside the main rotor mechanism 101 and are supported by the positioning spring 306 to always be engaged outward on the outer side of the hinge shaft 202 to limit the hinge shaft 202. When it is necessary to expand the hinge shaft 202 outward, only by pressing the pressing plate 307 inward can the hinge shaft 202 be automatically opened under the action of the torsion spring.
