[0002] There are various types of phone holders on the market, including those for cars, motorcycles, and bicycles. However, most of these phone holders lack shock absorption or have poor shock absorption. During vehicle operation, bumps and vibrations caused by road conditions can easily damage or malfunction the delicate components of the phone. Furthermore, existing phone holders offer limited angle adjustment, typically only allowing the phone to be placed horizontally or vertically, failing to meet users' needs for multi-angle adjustment.

[0003] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides a shock-absorbing rotating structure and a mobile phone holder, which solves the problems that the rotation angle of the existing mobile phone holder's rotation adjustment structure is relatively limited and does not have a shock-absorbing function.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A shock-absorbing rotary structure includes a fixed member, a rotating disk, and a limiting member. The fixed member is rotatably connected to the rotating disk. The rotating disk includes a movable member and a rotating member. The rotating member is non-rotatably connected to the movable member, and the movable member is floatingly connected to the fixed member.

[0007] The fixing member has a plurality of grooves, the rotating member has at least one protruding tooth corresponding to the groove, and the rotating member has an elastic arm for the protruding tooth to move elastically.

[0008] The limiting member is connected to the fixing member and the rotating disk to limit the floating stroke of the moving member;

[0009] When a circumferential external force is applied to the rotating disk, the protruding tooth disengages from the groove and slides to another groove, thereby achieving rotational positioning between the rotating disk and the fixed component.

[0010] In the above structure, the limiting member is a limiting screw, which has a sliding part and a threaded part. The threaded part is threadedly connected to the fixed end, and the diameter of the sliding part is larger than the diameter of the threaded part. The rotating disk is slidably sleeved on the sliding part.

[0011] In the above structure, the rotating component and the movable component are integrally formed, and the rotating component is formed on the side of the movable component facing the fixed component.

[0012] In the above structure, a floating spring is provided between the movable part and the fixed part, the fixed part is provided with a positioning post, the floating spring is movably sleeved on the positioning post, and one end of the floating spring abuts against the movable part and the other end abuts against the fixed part.

[0013] In the above structure, the rotating component and the movable component are detachably connected. The rotating component has a connecting shaft in the middle, and the movable component has a connecting part coaxial with the connecting shaft. The connecting part is movably sleeved on the connecting shaft along the connecting shaft axis, and the connecting part is non-rotatably connected to the connecting shaft.

[0014] In the above structure, a floating spring is provided between the movable part and the rotating part. The floating spring is movably sleeved on the connecting shaft, and one end of the floating spring abuts against the movable part and the other end abuts against the rotating part.

[0015] In the above structure, the protruding tooth is fixedly mounted on the elastic arm, and the elastic arm has a clearance hole near the center of the rotating part, allowing the elastic arm to be deformed inward.

[0016] In the above structure, the rotating component has three protruding teeth arranged in a uniform array on its outer periphery.

[0017] In the above structure, the floating stroke of the moving part is 2mm-2.5mm.

[0018] This utility model also provides a mobile phone holder, including a shock-absorbing rotating structure as described above.

[0019] The beneficial effects of this utility model are: the shock-absorbing rotating structure provided by this utility model is achieved by setting a fixed part, a rotating disk and a limiting part. The rotation angle of the rotating disk and the fixed part is adjusted by the cooperation of the teeth and the groove. The movable part is set to float and connect with the fixed part, which can effectively buffer the vibration and achieve the shock absorption effect. The floating stroke of the movable part is limited by the limiting part, which ensures the reliability and stability of the connection between the movable part and the fixed part.

[0020] By applying a shock-absorbing rotating structure to the phone holder, the phone holder can achieve multi-angle rotation adjustment, and the floating connection can buffer the impact of vibration and bumps on the phone during use, improving the shock absorption and buffering effect of the phone holder and effectively reducing the possibility of damage to the phone due to vibration and bumps.

Detailed Implementation

[0029] The following is in conjunction with the appendix Figure 1-6 The present invention will be further described below.

[0030] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0031] Example 1

[0032] Reference Figures 1 to 4This application provides a shock-absorbing rotating structure that can achieve both rotation angle adjustment and shock absorption. It includes a fixed component 1, a rotating disk 2, and a limiting component. The fixed component 1 and the rotating disk 2 are rotatably connected. During installation and use, the fixed component 1 can be externally connected to the fixed end of the accessory, and the rotating disk 2 is connected to the free end of the accessory. Angle adjustment is achieved by rotating the rotating disk 2. The fixed end is defined as the relatively fixed end, and the free end is defined as the relatively movable end. For example, when the shock-absorbing rotating structure is applied to a mobile phone holder, the fixed end is the holder base, and the free end is the mobile phone clamping part. Specifically, the rotating disk 2 includes a rotating component 22 and a movable component 21. The rotating component 22 is disposed between the movable component 21 and the fixed component 1, and the rotating component 22 is not rotatably connected to the movable component 21. The movable component 21 is floatingly connected to the fixed component 1. When the structure is subjected to vibration or shaking, the floating connection structure can buffer the vibration, thereby reducing damage to items mounted on the movable component 21 caused by vibration and achieving the purpose of shock absorption. The fixed component 1 has several grooves 11, and the rotating component 22 has at least one tooth 222 corresponding to a groove 11. The rotating component 22 also has an elastic arm 221 for the elastic movement of the tooth 222. When a circumferential external force is applied to the rotating disk 2, the elastic arm 221 undergoes elastic deformation under the force, causing the tooth 222 to disengage from the groove 11. When the tooth 222 slides to another groove 11, it elastically resets, thereby achieving rotational positioning between the rotating disk 2 and the fixed component 1. A limiting component is connected to the fixed component 1 and the rotating disk 2 to limit the floating stroke of the movable component 21, thereby ensuring the connection stability between the movable component 21 and the fixed component 1.

[0033] Reference Figure 1 and Figure 2 The fixing member 1 and the rotating disk 2 are rotatably connected. Specifically, the fixing member 1 is configured as a bowl-shaped structure, and the inner sidewall of the fixing member 1 is provided with a number of grooves 11. The rotating member 22 is configured as a hollow disk-shaped structure that at least matches the inner diameter of the fixing member 1. The rotating member 22 is provided with an elastic arm 221, and the protruding teeth 222 are fixedly disposed on the elastic arm 221. The elastic arm 221 has a relief hole 224 near the center of the rotating member 22. The elastic arm 221 can be squeezed and deformed inward so that the protruding teeth 222 can dislodge from the groove 11 and slide to another groove 11.

[0034] In this embodiment, three protruding teeth 222 are provided on the circumference of the rotating member 22, and the three protruding teeth 222 are evenly arrayed on the outer periphery of the rotating member 22. The three protruding teeth 222 form a stable structure, which is not prone to relative wobbling during use, so that the connection between the rotating member 22 and the fixed member 1 is stable and reliable. In addition, the frictional resistance of the three protruding teeth 222 is relatively small, which makes it convenient for the user to rotate and change the angle. In addition, the number of grooves 11 can be set as needed, and is not limited to one.

[0035] Reference Figure 2 and Figure 3 Furthermore, the limiting component is a limiting screw 3. Specifically, the limiting screw 3 is provided with a sliding part 31 and a threaded part 32. The rotating disk 2 has a central through hole 225, and the fixing component 1 has a mounting through hole 13 coaxial with the central through hole 225. The limiting screw 3 passes through the central through hole 225 and the mounting through hole 13 in sequence and is threaded to the fixing end. The rotating disk 2 is slidably connected to the sliding part 31.

[0036] Furthermore, the diameter of the sliding part 31 is larger than the diameter of the threaded part 32. When the threaded part 32 is threadedly connected to the fixed end, the bottom edge of the sliding part 31 presses the fixing member 1 against the fixed end, thereby realizing the installation and fixing of the fixing member 1.

[0037] In this embodiment, the movable part 21 and the rotating part 22 are detachably connected, that is, the movable part 21 and the rotating part 22 are separately arranged. Specifically, the rotating part 22 is provided with a connecting shaft 223 in the middle, and the movable part 21 is provided with a connecting part 211 coaxial with the connecting shaft 223 in the middle. The connecting part 211 is movably sleeved on the connecting shaft 223, and the connecting part 211 and the connecting shaft 223 are non-rotatably connected, that is, the connecting part 211 and the connecting shaft 223 will not rotate relative to each other under the action of force. The connecting part 211 can slide along the axial direction of the connecting shaft 223.

[0038] Reference Figures 2 to 4 Specifically, the non-rotational connection between the connecting part 211 and the connecting shaft 223 can be achieved by setting the connecting shaft 223 as a triangular, polygonal, or D-shaped structure, and setting the connecting part 211 as having a cavity that matches the shape of the connecting shaft 223, so as to fit onto the connecting shaft 223. In other embodiments, the non-rotational connection between the connecting part 211 and the connecting shaft 223 can also be set as other structural forms, which are not limited here.

[0039] In this embodiment, the movable part 21 and the connecting shaft 223 are respectively provided with through holes to form a central through hole 225 for mounting the limiting screw 3.

[0040] In this embodiment, a floating spring 4 is provided between the movable part 21 and the rotating part 22. The floating spring 4 is movably sleeved on the connecting shaft 223, with one end of the floating spring 4 abutting against the movable part 21 and the other end abutting against the rotating part 22. Under the action of the limiting screw 3 and the floating spring 4, the rotating part 22 abuts against the fixed part 1, realizing a tight connection of the entire structure and ensuring the controllability of the floating stroke.

[0041] Furthermore, by limiting the length of the sliding part 31 of the limiting screw 3 in conjunction with the size of the rotating disk 2, the floating stroke can be limited. In this application, the floating stroke is limited to 2mm-2.5mm, that is, the rotating disk 2 can float up and down the limiting screw 3 by a distance of 2mm-2.5mm. Limiting the floating stroke within this specific range ensures both shock absorption and reliable connection between the rotating disk 2 and the fixing member 1. If the floating stroke is set too large, the connection between the rotating disk 2 and the fixing member 1 will not be reliable enough, and items placed on the rotating disk 2 may shake abnormally during vibration; if the floating stroke is set too small, the shock absorption effect will not be achieved.

[0042] Example 2

[0043] Reference Figure 1 , Figure 5 and Figure 6 The difference between Embodiment 2 and Embodiment 1 is that, in order to simplify the structure and facilitate installation, the rotating part 22 and the movable part 21 are integrally formed to form the rotating disk 2, and the rotating part 22 is formed on the side of the movable part 21 facing the fixed part 1. A floating spring 4 is provided between the movable part 21 and the fixed part 1. A positioning post 12 is fixedly provided on the fixed part 1. The floating spring 4 is movably sleeved on the positioning post 12, and one end of the floating spring 4 abuts against the movable part 21, and the other end abuts against the fixed part 1.

[0044] In this embodiment, a mounting through hole 13 is formed on the positioning post 12 to provide a mounting through hole 13 for mounting the limiting screw 3. The threaded portion 32 of the limiting screw 3 passes through the central through hole 225 and the mounting through hole 13 in sequence, and is threadedly connected to the fixed end. The rotating disk 2 slides along the limiting screw on the sliding portion 31, and a floating connection is formed between the rotating disk 2 and the fixing member 1 under the action of the floating spring 4.

[0045] Based on the damping rotation structure described above, this application also provides:

[0046] A mobile phone holder includes the shock-absorbing rotating structure described above. Specifically, it includes a locking structure (as described above, the free end) and a clamping structure (as described above, the fixed end) for securing the mobile phone. A movable part 21 is fixedly connected to the locking structure, and the shock-absorbing rotating structure is connected and fixed to the clamping structure via the threaded portion 32 of a limiting bolt. When the mobile phone holder is used on a bicycle, the clamping structure can be connected and fixed to the bicycle handlebars to achieve the installation and fixation of the mobile phone.

[0047] With the aforementioned shock-absorbing rotating structure, after the clamping structure is tightened in the fixed position, the direction of the locking structure can be adjusted to adjust the angle of the phone, making it more convenient for users to use; and the shock-absorbing rotating structure can buffer the bumps and vibrations during riding, effectively protecting the phone.

Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
