Description

Technical Field

[0001] The utility model relates to the field of mobile phone holders, and particularly relates to a gravity holder. Background Art

[0002] Mobile phone holders are widely used in household cars. The holder is installed at the air outlet of the air conditioner through a fixed clip and used to clamp the mobile phone. Generally, the mobile phone holder is set as a gravity self-locking structure. By setting three linkage movable clamping arms, the mobile phone is placed on the lower clamping arm. The gravity of the mobile phone causes the lower clamping arm to move downward, and the clamping arms on the left and right sides move inward towards the mobile phone to clamp the mobile phone.

[0003] However, the existing mobile phone gravity holders can only be used when the mobile phone is placed vertically. If the mobile phone needs to be used horizontally, the length of the clamping arms is difficult to meet the requirement of horizontally clamping the mobile phone. Even if the vertically clamped mobile phone and the holder are rotated to the horizontal direction at the same time, there is no fixed structure between the clamping arms. After changing the relative position, one of the clamping arms originally in the left-right direction moves under the mobile phone, and the weight of the mobile phone will cause the lower clamping arm to move downward and open, and the mobile phone will fall off the holder. Therefore, it is necessary to further optimize the existing holder to simultaneously meet the vertical and horizontal use of the mobile phone when clamping. Summary of the Utility Model

[0004] An object of the utility model is to provide a mobile phone holder for solving the above problems.

[0005] To achieve the above utility model object, the utility model is realized by the following technical solutions:

[0006] A gravity bracket, comprising a main body, a clamping assembly and a locking assembly. A rotatable holder is provided on the back of the main body, and the holder mounts the bracket onto an area to be used. The clamping assembly includes a support base, a left clamping arm and a right clamping arm which are respectively movably connected to the main body. The support base, the left clamping arm and the right clamping arm extend from the main body along different directions. And when the support base moves downward under the gravity of the mobile phone, it can drive the left clamping arm and the right clamping arm to move inward into a clamping state to fix the mobile phone. The locking assembly includes a locking disk and a locking member. The locking disk is rotatably installed in the main body, and the locking member is fixedly or movably arranged at an eccentric position of the locking disk. Rotate the main body and the clamping assembly so that one of the left clamping arm and the right clamping arm is located below the mobile phone, and the support base is located in the left-right direction of the mobile phone. The locking member cooperates with the clamping assembly to enter a locking state, and the locking member directly or indirectly prevents the left clamping arm or the right clamping arm from moving downward under the gravity of the mobile phone. By adding a locking assembly to the main body, the mobile phone, the main body and the clamping assembly in the clamping state are rotated in the same direction at the same time. Using the cooperation and locking between the locking assembly and the clamping assembly, it is prevented that the clamping arm located at the lower end after the position is changed moves downward to release the mobile phone, so that the mobile phone can be used in combination with the bracket to meet the clamping use in both vertical and horizontal directions at the same time.

[0007] Preferably, a guide groove is provided at the eccentric position of the locking disk, and the locking member is movably installed in the guide groove. At least part of the locking member protrudes from the guide groove and can abut and cooperate with the support base to prevent the clamping assembly from moving in the direction of releasing the clamping state. When in the clamping state, the length of the support base located inside the main body changes according to the sizes of different mobile phones. The support base pushes the locking member to move in the guide groove to adjust the cooperation position. A first elastic member is provided between the locking member and the guide groove, and the elastic force of the first elastic member provides a abutting force for the locking member at different positions. Existing mobile phones have different length and width sizes according to different brands and models. When used with mobile phones of different length and width sizes, the moving path lengths of the support base, the left clamping arm and the right clamping arm are different. The settings of the guide groove and the first elastic member can adjust the position of the locking member in the guide groove according to the different moving paths of the support base, and rely on the elastic force of the first elastic member to maintain the locking cooperation between the locking member and the support base, so that the left clamping arm and the right clamping arm are both in the locking state, thus meeting the vertical and horizontal clamping use of mobile phones of various sizes.

[0008] Preferably, the main body includes a front cover and a rear cover which are fixedly connected. The rear cover is provided with an installation opening penetrating through the front and rear. The locking disk and the holder are circumferentially fixed and are respectively installed on the front and rear sides of the installation opening. Since the main body, the locking assembly and the holder need to rotate relative to each other when the bracket is in use, clamping the rear cover between the locking disk and the holder can ensure that the locking disk does not rotate when the main body is rotated.

[0009] Preferably, a limiting disk is provided on the locking disk. The limiting disk is inserted into the installation opening. A limiting block is provided on the outer periphery of the limiting disk, and an arc-shaped groove is provided on the edge of the installation opening. The limiting block and the arc-shaped groove cooperate to define the rotation angle of the main body relative to the fixator. The general usage requirement is for vertical and horizontal display of the mobile phone. The length of the arc-shaped groove is set to the length of a quarter circle arc, and the rotatable angle of the main body is limited within a range of 90°. When adjusting the angle of rotation, there is no need to control the rotation force to prevent the angle from being adjusted too large.

[0010] Preferably, a concave cavity is provided on the limiting disk, a limiting ring is provided in the concave cavity, a limiting portion is provided on the outer side of the limiting ring, a first groove is provided on the limiting disk at a position corresponding to the limiting portion, and second grooves are provided on the edge of the installation opening at intervals. The limiting portion passes through the first groove and is inserted into the second groove for positioning, so as to define the rotation angle of the main body relative to the fixator. The rotation angle of the main body can be limited solely by the limiting ring, or the rotation angle range of the main body can be limited by the combined action of the limiting ring, the limiting block, and the arc-shaped groove; the cooperation between the limiting portion and the second groove can keep the adjusted main body and the mobile phone positioned at this angle and position, avoiding the automatic deflection of the main body due to the shaking of the mobile phone, and making the horizontally clamped mobile phone more stable.

[0011] Preferably, a convex portion extending into the concave cavity is provided on the limiting disk on the side opposite to the first groove. The limiting ring is made of a deformable material. When the main body rotates relative to the locking disk, the convex portion pushes against the limiting ring to deform it so that the limiting portion is inserted into the second groove. The automatic insertion and separation cooperation between the limiting portion and the second groove is realized by the deformation of the limiting ring, making the rotation of the main body and the mobile phone more convenient.

[0012] Preferably, a convex platform is provided at the center of the locking disk. The convex platform extends backward along the concave cavity. The fixator is fixedly connected to the locking disk through the convex platform. The rear cover is provided with an annular groove on the outside of the installation opening. When the end of the fixator is installed, it is inserted into the annular groove. This makes the connection between the fixator and the main body, and the locking disk, more compact and stable.

[0013] Preferably, the clamping assembly further includes a rotating disk disposed between the front cover and the locking disk and rotatable relative to the main body. The rotating disk is provided with a first chute and a second chute extending outward from the center of the circle. The left clamping arm is provided with a first sliding pin, and the right clamping arm is provided with a second sliding pin. The first sliding pin is inserted into the first chute and can slide along the first chute. The second sliding pin is inserted into the second chute and can slide along the second chute. The rotating disk is further provided with a third sliding pin, and the upper end of the support base is provided with a third chute. The third sliding pin is inserted into the third chute and can slide along the third chute. When the support base moves downward, it drives the rotating disk to rotate and drives the left clamping arm and the right clamping arm to move toward each other to jointly clamp the mobile phone. The linkage of the support base, the left clamping arm and the right clamping arm is realized through the rotating disk. When the mobile phone is placed on the support base, the gravity of the mobile phone causes the support base, the left clamping arm and the right clamping arm to automatically move to the position where the mobile phone is clamped. The structure is simple and the use is convenient.

[0014] Preferably, the left clamping arm and the right clamping arm are installed on the front side of the rotating disk, and the support base is installed on the rear side of the rotating disk.

[0015] Preferably, a round platform protruding backward is provided in the middle of the rotating disk. When installed, the round platform is inserted into the locking disk for positioning. The round platform forms the rotating shaft of the rotating disk, enabling the rotating disk to rotate relative to the main body and the locking disk.

[0016] The advantages of the present utility model are as follows: By adding a locking component to the main body, the mobile phone, the main body and the clamping component in the clamped state are rotated in the same direction at the same time. The cooperation and locking between the locking component and the clamping component are utilized to prevent the clamping arm at the lower end from moving downward to loosen the mobile phone after the position is changed, so that the mobile phone can be used in combination with the bracket to meet the vertical and horizontal clamping requirements at the same time. Existing mobile phones have different length and width dimensions according to different brands and models. When used with mobile phones of different length and width dimensions, the moving path lengths of the support base, the left clamping arm and the right clamping arm are different. The setting of the guide groove and the first elastic member can adjust the position of the locking member in the guide groove according to the different moving paths of the support base, and rely on the elastic force of the first elastic member to maintain the locking cooperation between the locking member and the support base, so that the left clamping arm and the right clamping arm are simultaneously in the locked state, thus meeting the vertical and horizontal clamping requirements of mobile phones of various sizes.

The term "multiple" used herein refers to two or more numbers. The terms "vertical", "horizontal" and the like as used herein refer to a substantially vertical or substantially horizontal state within a reasonable error range and do not necessarily have to be very precise.

[0029] like Figures 1 - 10, A gravity bracket, comprising a main body 1, a clamping assembly and a locking assembly. A rotatable fixer 2 is provided on the back of the main body 1, and the fixer 2 mounts the bracket to the area to be used. The clamping assembly includes a support base 3, a left clamping arm 4 and a right clamping arm 5 that are respectively movably connected to the main body 1. The support base 3, the left clamping arm 4 and the right clamping arm 5 extend from the main body 1 along different directions. And the support base 3 moves downward under the gravity of the mobile phone, which can drive the left clamping arm 4 and the right clamping arm 5 to move inward into the clamping state to fix the mobile phone. The locking assembly includes a locking disc 6 and a locking member 7. The locking disc 6 is rotatably installed in the main body 1, and the locking member 7 is fixedly or movably arranged at an eccentric position of the locking disc 6. Rotate the main body 1 and the clamping assembly so that one of the left clamping arm 4 and the right clamping arm 5 is located below the mobile phone, and the support base 3 is located in the left-right direction of the mobile phone. The locking member 7 cooperates with the clamping assembly to enter the locking state, and the locking member 7 directly or indirectly prevents the left clamping arm 4 or the right clamping arm 5 from moving downward under the gravity of the mobile phone. By adding a locking assembly to the main body 1, the mobile phone, the main body 1 and the clamping assembly in the clamping state are rotated in the same direction at the same time. Using the cooperation and locking between the locking assembly and the clamping assembly, it is prevented that the clamping arm located at the lower end after the position is changed moves downward to release the mobile phone, so that the mobile phone can be used in combination with the bracket to simultaneously meet the vertical and horizontal clamping uses.

[0030] In this embodiment, the fixer 2 can be structures such as a fixed clip, a fixing glue, a fixing sticker, a magnet, a support rod, a support block, an insert piece, etc. The area to be used can be positions such as an automobile, a motorcycle, a bicycle, a desktop, etc. The bracket is installed at the required position through the fixer 2 and used in combination with the mobile phone. Of course, the mobile phone in the present invention is only used as an example. In addition to the mobile phone, it can also be a digital product such as a tablet computer or a speedometer. That is, the mobile phone in the present invention does not have a limiting effect. The mobile phone described in the present invention can be understood as an item to be clamped.

[0031] It should be noted that only a part of the fixer 2 is shown in the drawings of the present invention, and the overall structure of the fixer 2 is not shown. The fixer 2 is an existing technology in the art, and there are many types of the fixer 2, which will not be shown one by one in the present invention.

[0032] In this embodiment, the mobile phone is in a vertical state at the initial clamping position and is adjusted to a horizontal display after rotation. The horizontal and vertical directions are the positions in the length and width directions of a general smart phone. Of course, after making an adaptive adjustment to the length or moving length of each clamping arm, it can also be horizontal at the beginning and vertical after rotation; or the initial clamping and the clamping direction after rotation can be freely adjusted according to other types or sizes of items to be clamped. The present invention does not limit the initial clamping direction and position of the bracket, and the clamping direction and position after rotation. It only limits the function and method of rotation adjustment to meet the horizontal and vertical uses, that is, after using the content described in the present invention, it can be freely adjusted and clamped in the horizontal and vertical directions.

[0033] Since existing mobile phones have different length and width dimensions according to different brands and models, or different types of electronic products have different length and width dimensions, the locking component in this embodiment is arranged such that a guide groove 8 is provided at an eccentric position of the locking disk 6, the locking member 7 is movably installed in the guide groove 8, and at least a part of the locking member 7 extends out of the guide groove 8 and can abut against the support base 3 to prevent the clamping component from moving in the direction of releasing the clamping state. When in the clamping state, the length of the support base 3 located inside the main body 1 changes according to the size of different mobile phones. The support base 3 pushes the locking member 7 to move and adjust the fitting position in the guide groove 8. A first elastic member 9 is provided between the locking member 7 and the guide groove 8, and the elastic force of the first elastic member 9 provides a abutting force for the locking member 7 at different positions. When used with mobile phones and other electronic products of different length and width dimensions, the moving path lengths of the support base 3, the left clamping arm 4, and the right clamping arm 5 are different. The settings of the guide groove 8 and the first elastic member 9 can adjust the position of the locking member 7 in the guide groove 8 according to the different moving paths of the support base 3, and rely on the elastic force of the first elastic member 9 to maintain the locking fit between the locking member 7 and the support base 3, so that the left clamping arm 4 and the right clamping arm 5 are simultaneously in the locked state, thus meeting the vertical and horizontal clamping uses of mobile phones of various sizes.

[0034] Preferably, the main body 1 includes a front cover 10 and a rear cover 11 that are fixedly connected. The rear cover 11 is provided with an installation opening 12 that penetrates through the front and rear. The locking disk 6 and the fixator 2 are circumferentially fixed and are respectively installed on the front and rear sides of the installation opening 12. The clamping component and the locking component are both installed between the front cover 10 and the rear cover 11. And during production and assembly, first install the clamping component and the locking component on the front cover 10 or the rear cover 11, and then fixedly connect the other cover.

[0035] Preferably, a limit disk 13 is provided on the locking disk 6. The limit disk 13 is inserted into the installation opening 12. A limit block 14 is provided on the outer periphery of the limit disk 13. An arc-shaped groove 15 is provided on the edge of the installation opening 12. The limit block 14 cooperates with the arc-shaped groove 15 to limit the rotation angle of the main body 1 relative to the fixator 2.

[0036] In this embodiment, the preset adjustment angle of the main body 1 and the fixator 2 is 90°, that is, the angle required for vertical and horizontal adjustment of the mobile phone.

[0037] Preferably, a concave cavity 16 is provided on the limit disk 13, a limit ring 17 is provided in the concave cavity 16, a limit portion 18 is provided on the outer side of the limit ring 17, a first groove 19 is provided on the limit disk 13 at the position corresponding to the limit portion 18, and second grooves 20 are provided at intervals on the edge of the mounting opening 12. The limit portion 18 passes through the first groove 19 and is inserted into the second groove 20 for positioning, so as to limit the rotation angle of the main body 1 relative to the fixer 2. A convex portion 21 extending into the concave cavity 16 is provided on one side of the limit disk 13 relative to the first groove 19. The limit ring 17 is made of a deformable material. When the main body 1 rotates relative to the locking disk 6, the convex portion 21 pushes the limit ring 17 to deform so that the limit portion 18 is inserted into the second groove 20.

[0038] In this embodiment, the limit ring 17 and the limit portion 18 can be provided and used separately, or can be provided simultaneously with the limit block 14 and the arc-shaped groove 15 to jointly play a limiting role.

[0039] Preferably, a boss 22 is provided at the center of the locking disk 6. The boss 22 extends backward along the concave cavity 16. The fixer 2 is fixedly connected to the locking disk 6 through the boss 22. For example, the fixer 2 and the boss 22 are fixed by screws respectively. A circular groove 23 is provided on the outer side of the mounting opening 12 of the rear cover 11. When the end of the fixer 2 is installed, it is inserted into the circular groove 23.

[0040] In the above embodiment, the clamping assembly further includes a rotating disk 24. The rotating disk 24 is arranged between the front cover 10 and the locking disk 6 and can rotate relative to the main body 1. The rotating disk 24 is provided with a first sliding groove 25 and a second sliding groove 26 extending outward from the center of the circle. A first sliding pin 27 is provided on the left clamping arm 4, and a second sliding pin 28 is provided on the right clamping arm 5. The first sliding pin 27 is inserted into the first sliding groove 25 and can slide along the first sliding groove 25. The second sliding pin 28 is inserted into the second sliding groove 26 and can slide along the second sliding groove 26. A third sliding pin 29 is further provided on the rotating disk 24. A third sliding groove 30 is provided at the upper end of the support seat 3. The third sliding pin 29 is inserted into the third sliding groove 30 and can slide along the third sliding groove 30. When the support seat 3 moves downward, it drives the rotating disk 24 to rotate and drives the left clamping arm 4 and the right clamping arm 5 to move toward each other to jointly clamp the mobile phone.

[0041] Preferably, the left clamping arm 4 and the right clamping arm 5 are installed on the front side of the rotating disk 24, and the support seat 3 is installed on the rear side of the rotating disk 24.

[0042] A round platform 31 protruding backward is provided in the middle of the rotating disk 24. When the round platform 31 is installed, it is inserted into the locking disk 6 for positioning. The round platform 31 forms the rotating shaft of the rotating disk 24, so that the rotating disk 24 rotates relative to the main body 1 and the locking disk 6.

[0043] Preferably, a second elastic member 32 is further provided between the support seat 3 and the main body 1. After the mobile phone leaves the bracket, the elastic force of the second elastic member 32 enables the support seat 3, the left clamping arm 4, the right clamping arm 5 and the rotating disk 24 to automatically move back to their original positions.

[0044] In this embodiment, the first elastic member 9 and the second elastic member 32 may be structures such as springs and elastic adhesives.

[0045] When in use, place the mobile phone vertically on the support base 3. The support base 3 moves downward under the gravity of the mobile phone. The third sliding pin 29 and the third sliding groove 30 cooperate to cause the rotating disk 24 to rotate accordingly. The rotating disk 24 drives the left clamping arm 4 and the right clamping arm 5 to move towards each other through the cooperation of the first sliding pin 27, the first sliding groove 25, the second sliding pin 28 and the second sliding groove 26 to clamp the mobile phone. Rotate the mobile phone, the main body 1 and the clamping assembly simultaneously in the clockwise or counterclockwise direction. The fixer 2 and the locking disk 6 remain stationary. During the rotation of the mobile phone and the bracket, the top of the support base 3 approaches the locking member 7 until the support base 3 and the locking member 7 are in abutting cooperation. The rotation of the mobile phone and the bracket reaches the horizontal position and stops rotating. At this time, the support base 3 is located in the left-right direction of the mobile phone, and the left clamping arm 4 or the right clamping arm 5 is located below the mobile phone. The abutment of the locking member 7 prevents the support base 3 from moving towards the main body 1, so that the left clamping arm 4 or the right clamping arm 5 located below cannot move downward and open under the gravity of the mobile phone, and the mobile phone is locked in the horizontal use position.

[0046] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
