Description

Technical Field

[0001] This application relates to the field of mobile phone case technology, and particularly to a mobile phone holder. Background Art

[0002] The rotatable mobile phone holder provides great convenience for users when watching videos, live broadcasts, video conferences or taking selfies through its flexible rotation design. It can not only firmly support the mobile phone to ensure a stable viewing angle, but also allows users to freely adjust the angle according to their needs. Whether it is watching a movie in landscape mode, browsing the web in portrait mode, or finding the best selfie angle, it can be easily achieved.

[0003] Among them, the Chinese utility model patent, patent number: CN220754858U, discloses a mobile phone case holder. The holder body consists of a fixed frame and a movable frame. A rotating mechanism for flipping is provided at the connection between the fixed frame and the movable frame; the rotating mechanism includes a fixed block, a movable block and a connecting shaft. The connecting shaft passes through the movable block and is fixed to both ends of the fixed block, and the connecting shaft is in interference fit with the movable block to generate torsion to achieve the functions of rotation and self-locking; a circular rotating component is provided in the fixed frame. The rotating component includes a circular ring fixed cover, a circular ring bracket and a limiting elastic sheet arranged between the circular ring fixed cover and the circular ring bracket; multiple groups of limiting protrusions are provided on the limiting elastic sheet, and multiple groups of limiting grooves are provided on the fixed frame. The concave-convex fit between the limiting protrusions and the limiting grooves is achieved through the elastic force provided by the limiting elastic sheet to meet the function of concave-convex card point positioning, which is beneficial to popularization and application.

[0004] In the actual application process, the inventor found that: the rotating mechanism of the mobile phone case with this structure has a limiting mechanism to limit the angle of rotation of the movable frame along the fixed frame through the rotating mechanism. When the rotating mechanism carries the movable frame to move to the limiting mechanism, the movable frame is blocked from continuing to move through the limiting mechanism to solve the problem of mechanical interference between the components. However, when the angle of rotation of the movable frame along the fixed frame reaches the maximum value, if the user accidentally applies an external force to the mobile phone case, since the movable frame is connected to the fixed frame through the rotating mechanism, the movable frame will also bear this force. When the force is too large, there is a risk of deformation or fracture of the movable frame, and there is room for improvement. Summary of the Utility Model

[0005] In order to increase the maximum angle of rotation of the support frame along the mobile phone case, this application provides a mobile phone holder.

[0006] The mobile phone holder provided by this application adopts the following technical solutions:

[0007] A mobile phone holder, comprising a mobile phone case and a support frame rotatably connected to the mobile phone case, further comprising a first rotating component and a second rotating component. An activity space for the first rotating component and the second rotating component to act is formed between the mobile phone case and the support frame. The first rotating component includes a first rotating shaft and a first connecting arm, and the second rotating component includes a second rotating shaft and a second connecting arm. The first rotating shaft is arranged on the mobile phone case, the second rotating shaft is arranged on one side of the first rotating shaft, and the second rotating shaft is arranged parallel to the first rotating shaft. A damping mechanism is arranged between the mobile phone case and the support frame. Two ends of the first connecting arm are respectively rotatably connected to the first rotating shaft and the support frame, and two ends of the second connecting arm are respectively rotatably connected to the second rotating shaft and the damping mechanism. When an external force acts on the support frame, the first connecting arm and the second connecting arm act along the activity space. When the surface of the support frame abuts against the surface of the mobile phone case, the mobile phone case restricts the support frame from continuing to act along the mobile phone case.

[0008] By adopting the above technical solution, since the first rotating shaft and the second rotating shaft are arranged parallel to each other and the second rotating shaft is located on one side of the first rotating shaft, when a user applies an external force to the support frame to drive the support frame to rotate along the mobile phone case, two ends of the first connecting arm respectively rotate at the connection between the first rotating shaft and the support frame, and then two ends of the second connecting arm respectively rotate at the connection between the first rotating shaft and the limiting member until the surface of the support frame facing away from the mobile phone case abuts against the mobile phone case. Through the cooperation of the first connecting arm and the second connecting arm, the maximum angle of rotation of the support frame along the mobile phone case is increased.

[0009] Preferably, a connection seat is arranged on the surface of the support frame facing the mobile phone case, a pin shaft is arranged on the connection seat, and one end of the first connecting arm far from the connection with the first rotating shaft is rotatably connected to the pin shaft.

[0010] By adopting the above technical solution, through the cooperation of the connection seat and the pin shaft, the purpose of rotatably connecting one end of the first connecting arm far from the first rotating shaft to the support frame is achieved, the stability of the support frame when rotating along the mobile phone case is improved, and the probability of the support frame falling off at the connection with the mobile phone case is reduced.

[0011] Preferably, the damping mechanism includes a damping bushing and a damping rotating shaft. The damping bushing is arranged on the surface of the support frame facing the mobile phone case, the damping rotating shaft is fixedly connected to one end of the second connecting arm far from the connection with the second rotating shaft, and the damping rotating shaft penetrates through the damping bushing.

[0012] By adopting the above technical solution, when a user applies an external force to the support frame, causing the support frame to rotate along the mobile phone case, when the external force disappears, through the cooperation of the damping rotating shaft and the damping shaft sleeve, the support frame can hover at the current rotation angle.

[0013] Preferably, a fixing seat is provided on the mobile phone case, the first rotating shaft and the second rotating shaft are arranged on the fixing seat, the activity space includes a limiting groove and a limiting clamping platform, the limiting groove is arranged on the fixing seat, the limiting clamping platform is arranged on the surface of the support frame facing the mobile phone case, and a limiting block is arranged at one end of the first connecting arm connected to the support frame. When the surface of the support frame facing the mobile phone case is attached to the mobile phone case, the limiting block is located in the limiting groove. When the support frame rotates along the fixing seat and abuts against the mobile phone case, the limiting block abuts against the limiting clamping platform.

[0014] By adopting the above technical solution, when the support frame is in the initial state along the mobile phone case, the limiting clamping platform is located in the limiting groove, so as to limit the staying position of the first connecting arm along the fixing seat, improve the stability of the cooperation between the support frame and the accommodating groove. At the same time, through the accommodating effect of the limiting groove, the first connecting arm is located in the limiting groove, effectively solving the probability of the situation that when the first connecting arm is in the initial state, the first connecting arm protrudes from the surface of the fixing seat, thus affecting the flatness of the cooperation between the support frame and the surface of the mobile phone case. And the maximum rotation angle that the support frame can rotate along the fixing seat is limited by the limiting clamping platform, reducing the probability of the situation that when there is no mobile phone in the mobile phone case and the mobile phone case is deformed under the action of an external force, driving the support frame to deform synchronously, so that the movable part falls off or breaks along the fixed part.

[0015] Preferably, an accommodating groove is provided on the mobile phone case. When the support frame is in the initial state, the support frame is located in the accommodating groove, and a clamping position is provided on the support frame for the user to take out the support frame along the accommodating groove with the hand.

[0016] By adopting the above technical solution, the user can quickly rotate the support frame along the fixing seat through the clamping position, so as to take out the support frame along the accommodating groove.

[0017] Preferably, a hollow area is provided through the support frame in the thickness direction.

[0018] By adopting the above technical solution, the weight of the support frame is effectively reduced, which plays a positive guiding role in reducing the overall mass of the mobile phone case, and at the same time is convenient for the user to hold the mobile phone case by hand in a lifting manner.

[0019] Preferably, the accommodating groove is annularly arranged, and the fixing seat is slidably matched with the accommodating groove.

[0020] By adopting the above technical solution, the fixing base is in sliding fit with the accommodating groove, so that the fixing base can rotate along the accommodating groove, achieving the purpose of adjusting the staying position of the fixing base along the mobile phone case and meeting the purposes of horizontal and vertical placement of the mobile phone case.

[0021] Preferably, an installation groove is provided on the mobile phone case near the accommodating groove, the fixing base is located in the installation groove, and the fixing base is rotatably connected to the installation groove.

[0022] By adopting the above technical solution, an additional installation groove is provided at the accommodating groove of the mobile phone case, the fixing base is arranged in the installation groove, and the fixing base is rotatably connected to the installation groove, thereby defining the rotation path of the fixing base along the mobile phone case, with simple operation.

[0023] Preferably, a plurality of convex blocks are circumferentially arranged on the side wall of the fixing base in contact with the installation groove, and a clamping groove is arranged in the installation groove. When the fixing base rotates along the installation groove, the clamping groove can be in clamping fit with any one of the convex blocks.

[0024] By adopting the above technical solution, through the cooperation of the clamping groove and the plurality of convex blocks, after the fixing base rotates along the installation groove to a set angle, the clamping groove can be clamped with the convex block, so that the fixing base stably stays at the current angle along the mobile phone case, with high stability.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. Since the first rotating shaft and the second rotating shaft are arranged in parallel, and the second rotating shaft is located on one side of the first rotating shaft, thus, when the user applies an external force to the support frame to drive the support frame to rotate along the mobile phone case, both ends of the first connecting arm rotate at the connection between the first rotating shaft and the support frame respectively, and then both ends of the second connecting arm rotate at the connection between the first rotating shaft and the limiting member respectively until the surface of the support frame facing away from the mobile phone case abuts against the mobile phone case. Through the cooperation of the first connecting arm and the second connecting arm, the maximum rotation angle of the support frame along the mobile phone case is increased;

[0027] 2. Through the cooperation of the connecting seat and the pin shaft, the purpose of rotatably connecting one end of the first connecting arm far from the first rotating shaft to the support frame is achieved, improving the stability of the support frame when rotating along the mobile phone case.

[0028] 3. When the user applies an external force to the support frame, so that the support frame rotates along the mobile phone case, when the external force disappears, through the cooperation of the damping rotating shaft and the damping shaft sleeve, the support frame can hover at the current rotation angle; Description of the Drawings

The terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component, and they are relative concepts. Therefore, they may change accordingly according to their different positions and different usage states. Therefore, these or other orientations should not be construed as restrictive terms.

[0039] The following is combined with the attachedFigure 1-8 Further details of this application will be provided below.

[0040] Embodiment 1

[0041] This embodiment of the application discloses a mobile phone stand. Referring to Figures 1 to 4 and Figure 6 , a mobile phone stand includes a mobile phone case 1 and a support frame 2 rotatably connected to the mobile phone case 1. It also includes a first rotation assembly 3 and a second rotation assembly 4. An activity space 5 for the first rotation assembly 3 and the second rotation assembly 4 to act is formed between the mobile phone case 1 and the support frame 2. The first rotation assembly 3 includes a first rotation shaft 31 and a second connecting arm 42. The second rotation assembly 4 includes a second rotation shaft 41 and a second connecting arm 42. The first rotation shaft 31 is disposed on the mobile phone case 1. The second rotation shaft 41 is disposed on one side of the first rotation shaft 31 and is parallel to the first rotation shaft 31. A damping mechanism 6 is disposed between the mobile phone case 1 and the support frame 2. Both ends of the first connecting arm 32 are rotatably connected to the first rotation shaft 31 and the support frame 2 respectively. Both ends of the second connecting arm 42 are rotatably connected to the first rotation shaft 31 and the damping mechanism 6 respectively. When an external force acts on the support frame 2, the first connecting arm 32 and the second connecting arm 42 act along the activity space 5. When the surface of the support frame 2 abuts against the surface of the mobile phone case 1, the mobile phone case 1 restricts the support frame 2 from continuing to act along the mobile phone case 1.

[0042] First of all, it should be noted that the support frame 2 is used to support the mobile phone case 1. By adjusting the included angle formed between the support frame 2 and the mobile phone case 1, the purpose of changing the angle of the mobile phone case 1 offset in the vertical direction can be achieved. For the convenience of explanation, it is assumed that the two surfaces of the support frame 2 along the thickness direction are the first surface and the second surface respectively. When the first surface abuts against the mobile phone case 1, the support frame 2 is in a flat state (i.e., the support frame 2 is in an unoperated state). When the second surface abuts against the mobile phone case 1, it is the maximum angle at which the support frame 2 can rotate along the mobile phone case 1.

[0043] At the same time, the shape of the mobile phone case 1 can be changed according to actual design requirements, and its specific shape will not be described in detail here.

[0044] It should also be noted that in this embodiment, in order to improve stability, first connecting arms 32 are respectively disposed at both ends along the length direction of the first rotation shaft 31, and second connecting arms 42 are respectively disposed at both ends along the length direction of the second rotation shaft 41. The two first connecting arms 32 are symmetrically disposed about the length direction of the first rotation shaft 31, and the two second connecting arms 42 are symmetrically disposed about the length direction of the second rotation shaft 41. The connection methods of the two first connecting arms 32 and the two second connecting arms 42 with the support frame 2 and the mobile phone case 1 are the same. In the following description, any one of the first connecting arm 32 and the second connecting arm 42 at either end of the midline of the length direction of the first rotation shaft 31 will be described in detail.

[0045] Meanwhile, a fixing base 11 is provided on the mobile phone case 1. The first rotating shaft 31 and the second rotating shaft 41 are arranged on the fixing base 11. A first card slot 112 and a second card slot 113 are successively formed in the area between the edge of the fixing base 11 along the length direction and the midline of the fixing base 11 extending along the length direction. At the same time, through holes are respectively formed in the side walls of the fixing base 11 along the length direction along the length direction of the fixing base 11, and the through holes are respectively a first mounting hole and a second mounting hole. The first mounting hole and the second mounting hole are arranged at intervals along the width direction of the fixing base 11. The first mounting hole communicates with the first card slot 112, and the second mounting hole communicates with the second card slot 113.

[0046] The first rotating shaft 31 and the second rotating shaft 41 are respectively inserted into the first mounting hole and the second mounting hole. At the same time, one end of the first connecting arm 32 is rotatably connected to the first rotating shaft 31, and one end of the second connecting arm 42 is rotatably connected to the second rotating shaft 41, so as to achieve the purpose that the first connecting arm 32 can rotate along the first rotating shaft 31 and the second connecting arm 42 can rotate along the second rotating shaft 41.

[0047] Correspondingly, the first rotating shaft 31 and the second rotating shaft 41 are arranged one in front of the other, that is, the first rotating shaft 31 can be located in front of the second rotating shaft 41, and at the same time, the second rotating shaft 41 can be located in front of the first rotating shaft 31. However, the key point is that when the first rotating shaft 31 is located in front of the second rotating shaft 41, the length of the first connecting arm 32 should be greater than the length of the second connecting arm 42; when the second rotating shaft 41 is located in front of the first rotating shaft 31, the length of the second connecting arm 42 should be greater than the length of the second connecting arm 42.

[0048] For the convenience of description, in this embodiment, it is set that the first rotating shaft 31 is located in front of the second rotating shaft 41.

[0049] Therefore, since the first rotating shaft 31 and the second rotating shaft 41 are arranged in parallel and the second rotating shaft 41 is located on one side of the first rotating shaft 31, when the user needs to support the mobile phone case 1 with the support frame 2, an external force is applied to the support frame 2, so that the support frame 2 rotates along the mobile phone case 1. Both ends of the first connecting arm 32 rotate at the connection between the first rotating shaft 31 and the support frame 2, and then both ends of the second connecting arm 42 rotate at the connection between the first rotating shaft 31 and the limiting member until the second surface of the support frame 2 abuts against the mobile phone case 1. Through the cooperation of the first connecting arm 32 and the second connecting arm 42, the maximum angle of rotation of the support frame 2 along the mobile phone case 1 is increased.

[0050] Refer to Figure 3 and Figure 4, a connecting seat 21 is provided on the surface of the support frame 2 facing the mobile phone case 1. The connecting seat 21 is provided with a pin shaft 211. One end of the first connecting arm 32 far from the connection with the second connecting shaft is rotatably connected to the pin shaft 211, so as to realize that the first connecting arm 32 can rotate along the first rotating shaft 31, and at the same time, the support frame 2 can rotate along the pin shaft 211.

[0051] Referring to Figure 3 and Figure 4 , the damping mechanism 6 includes a damping bushing 61 and a damping rotating shaft 62. The damping bushing 61 is provided on the surface of the support frame 2 facing the mobile phone case 1. The damping rotating shaft 62 is fixedly connected to one end of the second connecting arm 42 far from the connection with the second rotating shaft 41. The damping rotating shaft 62 is inserted into the damping bushing 61.

[0052] Specifically, the damping bushing 61 is made of an elastic material to achieve the purpose of having a recoverable elastic deformation. The damping bushing 61 is provided with an activity groove 611 along the length direction, so that the damping bushing 61 is in an open state. The inner diameter of the damping bushing 61 is smaller than the diameter of the damping rotating shaft 62. Therefore, when the damping rotating shaft 62 is inserted into the damping bushing 61, the elastic restoring force provided by the damping bushing 61 is used to lock the damping rotating shaft 62, so as to realize that when the damping rotating shaft 62 is subjected to an external force, the damping rotating shaft 62 can rotate along the damping bushing 61. When the external force acting on the damping rotating shaft 62 disappears, the damping bushing 61 can quickly lock the damping rotating shaft 62, so as to realize the purpose that the support frame 2 connected to the damping bushing 61 hovers at the current angle.

[0053] Referring to Figure 4 and Figure 5 , the activity space 5 includes a limit groove 51 and a limit clamping platform 52. The limit groove 51 is provided on the fixed seat 11. The limit clamping platform 52 is provided on the surface of the support frame 2 facing the mobile phone case 1. A limit block 321 is provided at one end of the first connecting arm 32 connected to the support frame 2. When the surface of the support frame 2 facing the mobile phone case 1 is attached to the mobile phone case 1, the limit block 321 is located in the limit groove 51. When the support frame 2 rotates along the fixed seat 11 and abuts against the mobile phone case 1, the limit block 321 abuts against the limit clamping platform 52.

[0054] Specifically, the limit block 321 is formed by a protrusion at one end of the first connecting arm 32 facing the fixed seat 11. The limit groove 51 is formed by a depression of the fixed seat 11 along its thickness direction. The limit clamping platform 52 is formed by a depression of the surface of the support frame 2 facing the fixed seat 11 along the thickness direction of the support frame 2. When the first surface abuts against the mobile phone case 1, the limit block 321 is located in the limit groove 51, so that the connection between the support frame 2 and the mobile phone case 1 is relatively flat, reducing the amount of other components exposed outside the mobile phone case 1. At the same time, when the second surface abuts against the mobile phone case 1, the limit block 321 abuts against the limit clamping platform 52.

[0055] Its function is as follows: The maximum angle of rotation of the support frame 2 along the fixed seat 11 is limited by the limit clamping platform 52, reducing the probability that when there is no mobile phone in the mobile phone case 1 and the mobile phone case 1 is deformed under an external force, the mobile phone case 1 drives the support frame 2 to deform synchronously, resulting in the support frame 2 falling off or breaking along the fixed seat 11.

[0056] Refer to Figures 1-3 Any one of the figures, the support frame 2 is provided with a hollow area 7 penetrating along the thickness direction. The hollow area 7 is formed by the support frame 2 penetrating from the geometric center to the edge, effectively reducing the weight of the support frame 2, thus playing a positive guiding role in reducing the overall mass of the mobile phone case 1, and at the same time facilitating the user to hold the mobile phone case 1 by hand in a lifting manner.

[0057] Refer to Figure 1 and Figure 2 On the mobile phone case 1, a receiving groove 12 is provided. When the support frame 2 is in the initial state, the first surface of the support frame 2 is located in the receiving groove 12. The support frame 2 is provided with a clamping position 22, which is recessed from the side wall of the support frame 2 to the geometric center of the support frame 2. The clamping position 22 is used for the user to take out the support frame 2 along the receiving groove 12 with the hand. The user can quickly rotate the support frame 2 along the fixed seat 11 through the clamping position 22 to facilitate taking out the support frame 2 along the receiving groove 12.

[0058] The implementation principle of Embodiment 1 is: Since the first rotating shaft 31 and the second rotating shaft 41 are arranged in parallel, and the second rotating shaft 41 is located on one side of the first rotating shaft 31, when the user needs to use the support frame 2 to support the mobile phone case 1, an external force is applied to the support frame 2, so that the support frame 2 rotates along the mobile phone case 1. The two ends of the first connecting arm 32 rotate at the joints of the first rotating shaft 31 and the support frame 2 respectively, and then the two ends of the second connecting arm 42 rotate at the joints of the first rotating shaft 31 and the limiting member respectively until the second surface of the support frame 2 abuts against the mobile phone case 1. Through the cooperation of the first connecting arm 32 and the second connecting arm 42, the maximum angle of rotation of the support frame 2 along the mobile phone case 1 is increased.

[0059] Embodiment 2

[0060] The difference between Embodiment 2 and Embodiment 1 is: Refer to Figure 7 The receiving groove 12 is annularly arranged, and the fixed seat 11 is in sliding fit with the receiving groove 12. The fixed seat 11 is in sliding fit with the receiving groove 12, so that the fixed seat 11 can rotate along the receiving groove 12. At the same time, a limiting component is arranged in the receiving groove 12. Through the limiting component, after the fixed seat 11 rotates along the receiving groove 12, the fixed seat 11 can stay at the current position.

[0061] The implementation principle of Embodiment 2 is as follows: Since the accommodation groove 12 is arranged in a ring shape, the path of the rotation of the fixing base 11 along the mobile phone case 1 is defined, so as to adjust the staying position of the fixing base 11 along the mobile phone case 1, meeting the purpose that the mobile phone case 1 can be placed horizontally or vertically.

[0062] Embodiment 3

[0063] The difference between Embodiment 3 and Embodiment 2 is as follows: Referring to Figure 8 , an installation groove 13 is arranged on the mobile phone case 1 near the accommodation groove 12, the fixing base 11 is located in the installation groove 13, and the fixing base 11 is rotatably connected to the installation groove 13.

[0064] Specifically, the installation groove 13 is formed by the mobile phone case 1 being recessed in the thickness direction.

[0065] Meanwhile, a plurality of protrusions 111 are arranged circumferentially on the side wall of the fixing base 11 in contact with the installation groove 13, and a clamping groove is arranged in the installation groove 13. When the fixing base 11 rotates along the installation groove 13, the clamping groove can be clamped and matched with any one of the protrusions 111.

[0066] Among them, the number of the protrusions 111 can be increased or decreased according to the rotation angle range of the fixing base 11 along the installation groove 13, and no limitation is made thereto here.

[0067] The implementation principle of Embodiment 3 is as follows: Through the cooperation of the clamping groove and the plurality of protrusions 111, after the fixing base 11 rotates along the installation groove 13 to a set angle, the clamping groove can be clamped with the protrusion 111, so that the fixing base 11 can stably stay at the current angle along the mobile phone case 1, with high stability.

[0068] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
