Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Mobile phones, palm tablet computers and the like are mobile terminals commonly used in life of people. In daily use, in order to avoid the need to hold the mobile terminal for a long time, a mobile terminal bracket is often used to support and fix the mobile terminal.

In the related art, the ball head has the advantages of concentrated stress, stable support, simple appearance and the like, so the ball head is often applied to a rotating joint of a mobile terminal bracket as a hinge part. However, in the actual use process, the mobile terminal is easy to swing left and right due to the fact that the ball head can rotate in a universal mode, so that a user cannot directly view the display screen of the mobile terminal well, and the viewing experience of the user is reduced.

Based on the above, the embodiment of the application provides a mobile terminal bracket for supporting a mobile terminal. Specifically, the mobile terminal may be a mobile phone, a palm tablet computer, or the like, which is not limited in the embodiment of the present application.

Referring to fig. 1 to 3, fig. 1 is a schematic structural diagram of a mobile terminal bracket according to an embodiment of the present application, fig. 2 is a schematic structural diagram of a ball head of the mobile terminal bracket shown in fig. 1, and fig. 3 is a schematic partial part diagram of a fixing component of the mobile terminal bracket shown in fig. 1. The mobile terminal bracket may include a support base 100, a ball 200, and a fixing assembly 300. The ball 200 is fixedly connected with the supporting seat 100. The stationary assembly 300 is used to support a mobile terminal. The fixing assembly 300 is provided with a ball head accommodating cavity 31, and the ball head 200 is partially arranged in the ball head accommodating cavity 31 to be rotationally connected with the fixing assembly 300. Then, during use, the supporting base 100 may be prevented from being attached to a supporting plane such as a desktop, then the mobile terminal is fixed to the fixing assembly 300, and finally the mobile terminal may be adjusted to a proper angle for the user to watch by rotating the fixing assembly 300.

Wherein, the ball 200 is provided with a first limiting plane 21. The first limiting plane 21 is partially located in the ball head accommodating cavity 31, a limiting structure 331 matched with the first limiting plane 21 is arranged in the ball head accommodating cavity 31, and the limiting structure 331 is abutted against the first limiting plane 21, so that the axis of rotation of the fixing assembly 300 around the ball head 200 is perpendicular to the first limiting plane 21. Then, in the actual use process, the first limiting plane 21 may be located in the left-right direction of the ball head 200, so that the fixing assembly 300 can only turn over in the front-back direction or the back-to-front direction, and further the fixing assembly 300 and the mobile terminal can be well prevented from deflecting left and right in the process of adjusting the angle of the mobile terminal by the fixing assembly 300, so that the user can well look at the display screen of the mobile terminal.

In some embodiments, the limiting structure 331 may include a second limiting plane that abuts the first limiting plane 21.

In particular, the number of first limiting planes 21 may be one. Correspondingly, the number of the second limiting planes can also be one, and one first limiting plane 21 and one second limiting plane are mutually abutted.

Alternatively, the number of first limiting planes 21 may be two. The two first limiting planes 21 are parallel to each other. Correspondingly, the number of the second limiting planes can also be two, and each second limiting plane is abutted with one first limiting plane 21. Such as two first limiting planes 21 sandwiched between two second limiting planes. It can be appreciated that, by matching the two second limiting planes with the two first limiting planes 21, the force applied to the ball head 200 and the fixing assembly 300 is more uniform and reasonable, so that the fixing assembly 300 rotates more stably and reliably, and the service life of the mobile terminal bracket is prolonged.

Of course, in some other embodiments, the limiting structure 331 may also be other curved structures abutting against the first limiting plane 21, which is not limited in this embodiment of the present application.

In some embodiments, the ball head 200 may be provided with a non-circular hole 22 opening toward the support base 100, the non-circular hole 22 being a hole having a non-circular radial cross-section. The supporting seat 100 is provided with a connecting piece 123, and the connecting piece 123 is inserted into the non-circular hole 22, so that the ball head 200 and the supporting seat 100 can be connected and fixed. The connecting member 123 abuts against the inner wall of the non-circular hole 22 to limit the rotation of the ball head 200 relative to the support 100 about the axis of the non-circular hole 22.

It can be understood that, if the ball head 200 is sleeved on the connecting piece 123 through the circular hole, the ball head 200 is easily rotated in a horizontal plane relative to the supporting seat 100 after the fixing assembly 300 receives an external force, so that the fixing assembly 300 and the mobile terminal on the fixing assembly 300 are deflected left and right. In contrast, the cooperation between the connecting piece 123 and the non-circular hole 22 in the embodiments of the present application can well prevent the ball head 200 from rotating in a horizontal plane relative to the supporting seat 100, so as to avoid the fixed component 300 and the mobile terminal on the fixed component 300 from deflecting left and right, so that a user can better look at the display screen of the mobile terminal.

With continued reference to fig. 4 to 7, fig. 4 is a front view of the mobile terminal bracket and the mobile terminal protective case shown in fig. 1, fig. 5 is a cross-sectional view in A-A direction of fig. 4, fig. 6 is an exploded view of the mobile terminal bracket shown in fig. 4, and fig. 7 is a partially enlarged view at X in fig. 6. In some embodiments, the radial cross-section of the non-circular aperture 22 is rectangular, or it is also understood that the non-circular aperture 22 is a rectangular aperture. Accordingly, one end of the connecting member 123 inserted into the non-circular hole 22 has a rectangular parallelepiped structure fitted with the non-circular hole 22.

It can be appreciated that, compared to the non-circular hole 22 being a square hole, the rectangular hole can have a foolproof effect during the installation process, so as to avoid the first limiting plane 21 of the ball head 200 from the left-right direction to the front-back direction due to the misinstallation angle of the ball head 200, and further avoid that the display screen of the mobile terminal is not oriented to the user after the supporting seat 100 is fixed on the desktop or other places.

Of course, in some other embodiments, the non-circular holes 22 may also be oval holes, triangular holes, pentagonal holes, hexagonal holes, or shaped holes, etc., which are not limited in this example.

It will also be appreciated that the end of the connector 123 that is inserted into the non-circular aperture 22 may be the same shape as the non-circular aperture 22; such as triangular, square, pentagonal, etc. at both the end of the connector 123 inserted into the non-circular hole 22 and the end of the non-circular hole 22.

Alternatively, the end of the connecting member 123 inserted into the non-circular hole 22 may be shaped differently from the non-circular hole 22. For example, the non-circular hole 22 is square, one end of the connecting member 123 inserted into the non-circular hole 22 is triangular, or the non-circular hole 22 is pentagonal, one end of the connecting member 123 inserted into the non-circular hole 22 is quadrangular, which is not limited in the embodiment of the present application.

In some embodiments, to further fasten the ball head 200 to the support base 100, the mobile terminal bracket may further include a first fastening member disposed on the support base 100 and fixedly connected to the ball head 200.

Illustratively, the bottom wall of the non-circular bore 22 is provided with a first threaded bore 23. The first fastener may include a first fastening screw 124. The first fastening screw 124 is inserted through the connecting piece 123, and the first fastening screw 124 is screwed to the first threaded hole 23 to fix the connecting piece 123 and the ball head 200 in a screwed manner.

Then, it can be also understood that the connecting piece 123 is multiplexed to the first fastening screw 124, so that the overall structure of the mobile terminal bracket is more compact, and meanwhile, the first fastening screw 124 can be hidden in the connecting piece 123 and the ball head 200, so that the appearance of the mobile terminal bracket is more concise and attractive.

Optionally, the first fastener may further include a buckle, a tension member, a rivet, and the like, which is not limited in this embodiment.

In some embodiments, the connection 123 and the support base 100 may be integrally formed. For example, the connection member 123 and the support base 100 may be integrally formed by injection molding, milling, die casting, or the like.

Alternatively, the connecting member 123 and the supporting base 100 may be of a fractal structure. For example, the connecting member 123 is fixed to the supporting seat 100 by a fastening, a screwing, a plugging, or the like, or the connecting member 123 is non-detachably fixed to the supporting seat 100 by welding, fusion, or an adhesive, which is not limited in the embodiment of the present application.

In some embodiments, the support base 100 may include a base 11 and a support column 12. The support column 12 is mounted on the base 11, and the ball 200 is disposed on an end surface of the support column 12 opposite to the base 11. Alternatively, it is understood that the ball head 200 is mounted to the top surface of the support column 12.

Then, taking the example of two users sitting face to face, since the ball 200 is disposed on the top surface of the support column 12, the fixing assembly 300 can be rotated at a large angle such as 270 ° from front to back or back to front, so that the mobile terminal can be rotated to the user facing the front side following the fixing assembly 300, and so that the mobile terminal can be rotated to the user facing the rear side following the fixing assembly 300. Meanwhile, in combination with the non-circular hole 22 structure and the first limiting plane 21 structure, the application embodiment can prevent the fixed assembly 300 and the mobile terminal on the fixed assembly 300 from deflecting left and right in the front-back overturning process by double means, so that a user can better directly view the display screen of the mobile terminal.

In some embodiments, the support 100 may further include a weight 13. The support column 12 can be hollow structure, and balancing weight 13 is acceptd in support column 12 and is fixed with base 11 spiro union to make the mobile terminal support can place more stably. Meanwhile, the manner of arranging the balancing weight 13 in the supporting column 12 can also enable the area of the base 11 to be smaller and still stably support the mobile terminal.

The connecting member 123 and the supporting seat 100 may be integrally formed, and then the connecting member 123 may be integrally formed on an end surface of the supporting column 12 facing away from the base 11. For example, the support column 12 may include a hollow column 121 and a top cover 122 disposed at an end of the column 121 opposite to the base 11, and the connecting member 123 is integrally formed with the top cover 122.

And, the first fastening screw 124 may be screwed with the ball 200 after passing through the connection member 123 from the inside of the support column 12 such as the top cover 122 described above, thereby hiding the first fastening screw 124 to make the whole of the mobile terminal stand more beautiful.

The foregoing is illustrative of some of the alternative configurations of the ball head 200 and the support base 100 in the embodiments of the present application, and the following description of the clearance of the fixing assembly 300 in the embodiments of the present application is continued.

The securing assembly 300 may include a blade 32 and a ball cover 33. The carrier 32 is used to support and secure the mobile terminal. The supporting plate 32 is fixedly connected with the ball sleeve 33. The supporting plate 32 and the head sleeve 33 are surrounded to form a ball head accommodating cavity 31.

Then the limiting structure 331 further includes a second limiting plane, and two bosses are protruding from the inner wall of the ball cover 33, where the two bosses are opposite to each other. Each boss forms the second limit plane towards one side surface of the other boss.

In some embodiments, the securing assembly 300 further includes a resilient member 34. The elastic member 34 is accommodated in the ball accommodating cavity 31, and the ball 200 abuts against the elastic member 34 to form a rotation fit. Further, by providing the elastic member 34, the rotational damping between the fixing assembly 300 and the ball 200 can be increased.

Specifically, the elastic member 34 may be a silicone member, a rubber member, or the like, which is not limited in the embodiment of the present application.

In some embodiments, the securing assembly 300 may also include a magnet 35. The magnet 35 is provided to the pallet 32. So that the fixing member 300 can be attached to the mobile terminal by means of magnetic attachment.

The number of the magnets 35 may be one, or may be plural, such as two, three, four, or five, which is not limited in the embodiment of the present application.

Taking the example that the number of the magnets 35 is a plurality, the plurality of magnets 35 may be spaced apart so that the fixed assembly 300 may form a plurality of magnetic connections between mobile terminals; furthermore, on one hand, the force applied to the fixing assembly 300 can be more uniform and reasonable, and on the other hand, the automatic positioning of the mobile terminal after the mobile terminal is placed on the supporting plate 32 can be realized through the point-to-point matching of the mobile terminal and the magnets 35 on the supporting plate 32.

Illustratively, the pallet 32 is an aluminum alloy material. The four corners of the supporting plate 32 are respectively provided with a first mounting hole, and the opening of the first mounting hole is positioned on one side surface of the supporting plate 32, which is opposite to the ball sleeve 33. At least one magnet 35 is mounted within each first mounting hole.

Of course, the pallet 32 may be made of other hard plastics, non-magnetic metals or non-magnetic alloys, which are not limited in this embodiment. So that the pallet 32 is not magnetized by the magnet 35 while the rigidity of the pallet 32 is ensured.

In some embodiments, the fixing assembly 300 further includes a first protection layer 36, where the first protection layer 36 is disposed on a side surface of the supporting plate 32 facing away from the ball socket 33, and the first protection layer 36 covers the magnet 35. Thereby providing protection to the pallet 32 through the first protective layer 36 and concealing the magnets 35 through the first protective layer 36 to enhance the aesthetic appeal of the securing assembly 300.

The first protective layer 36 may be of silicone material. On the one hand, the friction force of the silica gel material is larger, and when the mobile terminal is placed on the supporting plate 32, the first protection layer 36 made of the silica gel material can be in contact with the mobile terminal, so that the friction force between the supporting plate 32 and the mobile terminal is increased, and the falling possibility of the mobile terminal is reduced. On the other hand, since the silica gel material has good elastic deformation capability, damage between the mobile terminal and the fixed assembly 300 due to collision can be well prevented in the process of placing the mobile terminal on the supporting plate 32.

In some embodiments, the securing assembly 300 further includes a first adhesive layer 37, the first protective layer 36 being adhesively secured to the pallet 32 by the first adhesive layer 37.

With continued reference to fig. 8, fig. 8 is an exploded view of the mobile terminal protective case shown in fig. 4. The embodiment of the application also provides a mobile terminal bracket kit. The mobile terminal stand kit may include a mobile terminal stand and a mobile terminal protective case 400. The mobile terminal holder may be the mobile terminal holder described above. The mobile terminal protective case 400 is used to be sleeved to a mobile terminal. The mobile terminal protective case 400 includes a plurality of magnetic members 42 disposed at intervals. The magnetic member 42 is magnetically coupled to the fixing assembly 300.

The magnetic member 42 may be a magnet or a magnetic metal, which is not limited in the embodiment of the present application.

The number of the magnets 35 is plural, so that the plural magnetic members and the plural magnets 35 may be in one-to-one correspondence, or each magnetic member corresponds to one magnet 35. Furthermore, on one hand, the force applied to the fixing assembly 300 can be more uniform and reasonable, and on the other hand, the automatic positioning of the mobile terminal protective housing 400 after being placed on the supporting plate 32 can be realized through the point-to-point matching of the plurality of magnetic pieces 42 and the plurality of magnets 35.

In some embodiments, the mobile terminal case 400 may further include a case body 41, and the case body 41 is formed with a fixing cavity 411, and the fixing cavity 411 is used to receive a mobile terminal to fix the mobile terminal. Thereby protecting the mobile terminal through the protective case body 41.

In some embodiments, the protective housing body 41 may include a hard body 412 and a silicone sleeve 413 surrounding the hard body 412.

The hard body 412 may be made of hard plastic such as PC (Polycarbonate), and may have a good supporting effect. The silica gel cover 413 can improve the friction force of the mobile terminal protection housing 400, so as to reduce the falling possibility of the mobile terminal protection housing 400 and the mobile terminal. And, the silica gel cover 413 can improve the buffer capacity of mobile terminal protection to avoid the damage of the mobile terminal protection shell 400 and the mobile terminal.

In some embodiments, the hard body 412 may be provided with a second mounting hole into which the magnetic member 42 is embedded to achieve a mounting fixture. Meanwhile, the magnetic piece 42 is covered by the silica gel sleeve 413 wrapped on the surface of the hard main body 412, so as to improve the aesthetic feeling of the mobile terminal protection shell 400.

In some embodiments, the protective housing 41 further includes a fleece layer 414, and the fleece layer 414 is disposed on an inner wall of the fixing cavity 411. On the one hand, the flannelette layer 414 can play a good decorative effect on the mobile terminal protective housing 400, and on the other hand, the flannelette layer 414 can also prevent the mobile terminal from being scratched by the protective housing body 41 after being installed in the fixing cavity 411.

The embodiment of the application also provides a rotating shaft assembly. The rotating shaft assembly is applied to a supporting device, and the supporting device can be the mobile terminal bracket, or can be a bracket of some display devices such as televisions, computer display screens and the like, which is not limited in the embodiment of the application. The spindle assembly may include a connector 123, a ball head 200, and a fixing assembly 300.

The ball 200 is provided with a non-circular hole 22, the connecting piece 123 is inserted into the non-circular hole 22, and the connecting piece 123 abuts against the inner wall of the non-circular hole 22 to limit the ball 200 to rotate around the axis of the non-circular hole 22. The ball 200 further comprises two first limiting planes 21 parallel to each other, and the non-circular hole 22 is located between the two first limiting planes 21. The fixing assembly 300 is provided with a ball head accommodating cavity 31, and the ball head 200 is partially arranged in the ball head accommodating cavity 31 to be rotationally connected with the fixing assembly 300. The first limiting plane 21 is partially disposed in the ball accommodating cavity 31. The ball head accommodating cavity 31 is internally provided with a limiting structure 331, and the limiting structure 331 is abutted against the first limiting plane 21, so that the axis of rotation of the fixing assembly 300 around the ball head 200 is perpendicular to the first limiting plane 21.

Then, taking the example that the two first limiting planes 21 are respectively located at the left side and the right side of the ball head 200, the ball head 200 can be well prevented from rotating in the horizontal plane relative to the connecting piece 123 by matching the connecting piece 123 and the non-circular hole 22, so that the left-right deflection of the fixing assembly 300 is avoided. Further, the first limiting plane 21 can enable the fixing assembly 300 to be turned only along the front-to-back or back-to-front direction, so as to avoid the fixing assembly 300 from deflecting left and right. Finally, the fixing assembly 300 can be more stable in the rotating process through double limiting, and left and right shaking can not occur.

In some embodiments, the limiting structure 331 may include two second limiting planes, each of which abuts one of the first limiting planes 21. Such as two first limiting planes 21 sandwiched between two second limiting planes. It can be appreciated that, by matching the two second limiting planes with the two first limiting planes 21, the force applied to the ball head 200 and the fixing assembly 300 is more uniform and reasonable, so that the fixing assembly 300 rotates more stably and reliably, and the service life of the mobile terminal bracket is prolonged.

Of course, in some other embodiments, the limiting structure 331 may also be other curved structures abutting against the first limiting plane 21, which is not limited in this embodiment of the present application.

In some embodiments, the radial cross-section of the non-circular aperture 22 is rectangular, or it is also understood that the non-circular aperture 22 is a rectangular aperture. Accordingly, one end of the connecting member 123 inserted into the non-circular hole 22 has a rectangular parallelepiped structure fitted with the non-circular hole 22.

It can be appreciated that, compared to the non-circular hole 22 being a square hole, the rectangular hole can have a foolproof effect during the installation process, so as to avoid the first limiting plane 21 of the ball head 200 from the left-right direction to the front-back direction due to the misinstallation angle of the ball head 200, and further avoid that the display screen of the mobile terminal is not oriented to the user after the supporting seat 100 is fixed on the desktop or other places.

Of course, in some other embodiments, the non-circular holes 22 may also be oval holes, triangular holes, pentagonal holes, hexagonal holes, or shaped holes, etc., which are not limited in this example.

It will also be appreciated that the end of the connector 123 that is inserted into the non-circular aperture 22 may be the same shape as the non-circular aperture 22; such as triangular, square, pentagonal, etc. at both the end of the connector 123 inserted into the non-circular hole 22 and the end of the non-circular hole 22.

Alternatively, the end of the connecting member 123 inserted into the non-circular hole 22 may be shaped differently from the non-circular hole 22. For example, the non-circular hole 22 is square, one end of the connecting member 123 inserted into the non-circular hole 22 is triangular, or the non-circular hole 22 is pentagonal, one end of the connecting member 123 inserted into the non-circular hole 22 is quadrangular, which is not limited in the embodiment of the present application.

In some embodiments, to further fasten the ball head 200 to the support 100, the connection member 123 may have a first fastening member fixedly connected to the ball head 200.

Illustratively, the bottom wall of the non-circular bore 22 is provided with a first threaded bore 23. The first fastener may include a first fastening screw 124. The first fastening screw 124 is inserted through the connecting piece 123, and the first fastening screw 124 is screwed to the first threaded hole 23 to fix the connecting piece 123 and the ball head 200 in a screwed manner.

Then, it can be also understood that the connecting piece 123 is multiplexed to the first fastening screw 124, so that the overall structure of the mobile terminal bracket is more compact, and meanwhile, the first fastening screw 124 can be hidden in the connecting piece 123 and the ball head 200, so that the appearance of the mobile terminal bracket is more concise and attractive.

Optionally, the first fastener may further include a buckle, a tension member, a rivet, and the like, which is not limited in this embodiment.

In some embodiments, the securing assembly 300 further includes a resilient member 34. The elastic member 34 is accommodated in the ball accommodating cavity 31, and the ball 200 abuts against the elastic member 34 to form a rotation fit. Further, by providing the elastic member 34, the rotational damping between the fixing assembly 300 and the ball 200 can be increased.

Specifically, the elastic member 34 may be a silicone member, a rubber member, or the like, which is not limited in the embodiment of the present application.

In the foregoing embodiments, the descriptions of the embodiments are emphasized, and for parts of one embodiment that are not described in detail, reference may be made to related descriptions of other embodiments.

The mobile terminal bracket, the external member and the rotating shaft assembly thereof provided by the embodiment of the application are described in detail, and specific examples are applied to the description of the principle and the implementation of the application, and the description of the above examples is only used for helping to understand the method and the core idea of the application; meanwhile, as those skilled in the art will vary in the specific embodiments and application scope according to the ideas of the present application, the contents of the present specification should not be construed as limiting the present application in summary.
