Description

Technical Field

[0001] This application relates to the field of support devices, and in particular to a mobile phone holder. Background Technology

[0002] As people's demands for quality of life and work efficiency continue to rise, their needs for the usage scenarios and methods of electronic devices are also becoming increasingly diverse. To meet users' needs in different scenarios, many electronic devices require stands to achieve functions such as angle adjustment. For example, when watching videos, people want their phones to be placed at a comfortable angle for a better viewing experience; when giving presentations or monitoring, small displays need to be fixed at a suitable angle with a stand to provide users with a more convenient and efficient operating experience. The existence of stands allows electronic devices to better adapt to different environments and tasks, significantly improving the practicality of the devices and user satisfaction, further promoting the widespread application of electronic devices in various fields.

[0003] One existing mobile phone holder includes a mobile phone case and a support frame rotatably connected to the mobile phone case. It also employs a first rotating component and a second rotating component, forming an movable space 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. A damping mechanism is provided between the mobile phone case and the support frame. The two ends of the first connecting arm are rotatably connected to the first rotating shaft and the support frame, respectively. The two ends of the second connecting arm are rotatably connected to the second rotating shaft and the damping mechanism, respectively. The damping mechanism includes a damping bushing and a damping rotating shaft. The damping bushing is disposed on the surface of the support frame facing the mobile phone case. The damping rotating shaft is fixedly connected to the end of the second connecting arm away from the end connected to the second rotating shaft. The damping rotating shaft passes through the damping bushing. When the support frame is subjected to an external force, the first connecting arm and the second connecting arm move along the movable space to realize the rotation of the support frame and the adjustment of a larger angle.

[0004] However, in practical applications, the inventors found that the above-mentioned bracket still has obvious defects: the complex mechanical structure of the existing mobile phone bracket makes its assembly process cumbersome and requires a lot of time and effort to assemble. Since the first connecting arm and the second connecting arm are independent of each other and both are connected to the support frame, the rotation of the bracket drives the rotation of the two connecting arms. If the installation is not precise enough, interference problems can easily occur during the rotation of the bracket, resulting in the bracket not rotating smoothly when in use. Utility Model Content

[0005] To improve the smoothness of mobile phone holder rotation, enhance installation convenience, and effectively prevent interference during holder rotation, this application provides a mobile phone holder.

[0006] This application provides a mobile phone holder, including a mobile phone case, a rotating structure, and a support frame. The mobile phone case has a placement groove, and the support frame is rotatably mounted in the placement groove via the rotating structure, with a hollow area in its middle. The rotating structure includes two first mounting seats for connecting the support frame, a second mounting seat for connecting the mobile phone case, two connecting rods, and a damping structure. The two first mounting seats are rotatably connected to the second mounting seats via the connecting rods. The damping structure includes a damping bushing and a damping shaft. The damping bushing is fitted onto the damping shaft, and its bottom extends downward to form an extension rotatably connected to the second mounting seat. The two sides of the first mounting seats are rotatably connected to the connecting rods and the damping shaft, respectively. When the support frame rotates, the first mounting seats drive the damping shaft to rotate relative to the damping bushing. By adopting the above technical solution, the rotating structure includes two first mounting seats for connecting the support frame, a second mounting seat for connecting the phone case, two connecting rods, and a damping structure. Both first mounting seats are rotatably connected to the second mounting seats via connecting rods, and each side of the first mounting seat is rotatably connected to the connecting rod and the damping shaft, respectively. When the support frame rotates, the first mounting seats drive the damping shaft to rotate relative to the damping sleeve fitted outside them. This structural design allows the damping structure to function during the rotation of the support frame. The damping structure provides resistance, preventing the support frame from rotating too flexibly and becoming difficult to position, thus allowing the support frame to stably remain at any rotation angle, meeting the user's needs for phone placement angles in different scenarios. Furthermore, compared to existing complex mechanical phone holders, this rotating structure reduces unnecessary complex connections and transmission components, lowers assembly difficulty, and reduces assembly time and effort. Due to the simplified structure, it is easier to ensure installation accuracy during installation, avoiding rotational interference problems caused by inaccurate installation, resulting in smoother rotation of the support frame. Preferably, the first mounting base has a damping groove on the side near the damping shaft, and the damping shaft extends into the damping groove and is fixedly connected to the first mounting base. By adopting the above technical solution, with the damping groove on the side of the first mounting base near the damping shaft, and the damping shaft extending into the damping groove and fixedly connected to the first mounting base, the first mounting base can stably drive the damping shaft to rotate when the support frame rotates. Because the damping shaft is fixedly connected to the first mounting base, relative sliding or displacement between the two is avoided, allowing the rotational action of the first mounting base to be accurately transmitted to the damping shaft, thereby enabling the damping shaft to rotate stably relative to the damping bushing. This ensures the smoothness and stability of the rotation process, effectively preventing interference and other problems during rotation, and improving the reliability of the phone holder's rotation and the user experience. Preferably, a connecting shaft extends from the side of the first mounting base near the connecting rod, the connecting shaft passing through the end of the connecting rod and being rotatably connected to the connecting rod.By adopting the above technical solution, a connecting shaft extends from the side of the first mounting base near the connecting rod. This connecting shaft passes through the end of the connecting rod and is rotatably connected to it, thus forming a rotatable connection between the first mounting base and the connecting rod. When the support frame rotates, the first mounting base moves accordingly. Due to the connecting shaft, the rotational motion of the first mounting base can be stably transmitted to the connecting rod, ensuring effective force transmission during rotation, thereby making the rotation of the support frame smoother and more stable. Preferably, a first receiving groove is provided on the side of the second mounting base away from the hollow area. When the support frame is closed, the damping structure is located in the first receiving groove. By adopting the above technical solution, since a first receiving groove is provided on the side of the second mounting base away from the hollow area, the damping structure can be housed in the first receiving groove when the support frame is closed. In this way, the damping structure avoids occupying extra space when the support frame is closed, making the overall structure of the phone holder more compact, reducing the space occupied by the holder when not in use, meeting the requirements of the thin and light design of the phone case, and facilitating carrying and storage. Preferably, the second mounting base has a second receiving groove at its top, and the connecting rod is located within the second receiving groove when the support frame is closed. By adopting the above technical solution, the second mounting base has a second receiving groove at its top, allowing the connecting rod to be located within the second receiving groove when the support frame is closed. Since the connecting rod can be stored in the second receiving groove when the support frame is closed, the entire phone holder has a more compact structure in its stored state, reducing unnecessary space occupation and preventing the connecting rod from protruding externally. This structure facilitates the carrying and storage of the phone holder and meets the requirements of a thin and light phone case design. Preferably, an arc-shaped transition portion is formed between the damping bushing and the extension, and the arc-shaped transition portion is recessed towards the first receiving groove. By adopting the above technical solution, an arc-shaped transition portion is formed between the damping bushing and the extension portion, recessed towards the first receiving groove. Due to the recessed design of this arc-shaped transition portion, when the support frame is closed, it provides a more reasonable spatial layout for components such as the damping structure and the connecting rod, avoiding interference between components, making the rotation process of the support frame smoother, and also making the entire phone holder structure more compact and reducing space occupation. Preferably, a third receiving groove is provided on the side of the arc-shaped transition portion away from the first receiving groove. When the support frame is closed, the first mounting seat is located within the third receiving groove. By adopting the above technical solution, since the third receiving groove is provided on the side of the arc-shaped transition portion away from the first receiving groove, the first mounting seat will move when the support frame is closed. The existence of the third receiving groove provides a receiving space for the first mounting seat, so that the first mounting seat can be located exactly within the third receiving groove. This makes the phone holder more compact in structure when the support frame is closed, reduces the space occupied, facilitates carrying and storage, and meets the requirements of the thin and light design of the phone case.Preferably, the rotating structure further includes a third mounting base. The connecting rod is rotatably connected to the second mounting base via a first rotating shaft, and the extension is rotatably connected to the second mounting base via a second rotating shaft. The third mounting base is disposed at the bottom of the second mounting base, and all third mounting bases are rotatably connected to both the first and second rotating shafts. By adopting the above technical solution, the rotating structure is provided with a third mounting base, and all third mounting bases are rotatably connected to the first and second rotating shafts. The connecting rod is rotatably connected to the second mounting base via the first rotating shaft, and the extension is rotatably connected to the second mounting base via the second rotating shaft. In this way, the third mounting base can support and position the first and second rotating shafts, making them more stable during rotation. When the support frame rotates, the first mounting base drives the damping shaft to rotate relative to the damping bushing. During this process, the first and second rotating shafts will bear corresponding forces. The third mounting base ensures stable rotation of the first and second rotating shafts, avoiding wobbling or deviation, thereby making the rotation of the entire rotating structure smoother and effectively improving the stability and reliability of the phone holder rotation. Preferably, the second mounting base has a limiting post at its bottom, and the third mounting base has a limiting hole that forms a limiting fit with the limiting post. By adopting the above technical solution, with the limiting post at the bottom of the second mounting base and the limiting hole in the third mounting base, when the third mounting base mates with the second mounting base, the limiting post inserts into the limiting hole. This limiting fit precisely limits the installation position and angle of the third mounting base relative to the second mounting base, preventing the third mounting base from shifting or misaligning during installation. Because the installation position and angle are accurately defined, the various components in the rotating structure can be installed and mated according to design requirements, thereby ensuring the stability and reliability of the rotating structure. Preferably, the rotating structure also includes an elastic clamping seat, with a groove on the outer wall of the second mounting base, and the elastic clamping seat embedded between the groove wall and the placement groove wall. By adopting the above technical solution, since the outer wall of the second mounting base is provided with a groove, the elastic clamping seat is embedded between the groove wall and the placement groove wall. The elastic clamping seat is elastic and can adapt to the size of the groove and the placement groove through its own elastic deformation during installation, and is tightly clamped between the two, thereby realizing a stable connection between the rotating structure and the phone case placement groove, avoiding problems such as loosening and shaking of the rotating structure during use, ensuring the stability of the overall structure of the phone holder, and improving the ease of installation of the support frame.

[0007] In summary, this application includes at least one of the following beneficial technical effects: 1. The rotating structure consists of a first mounting base, a second mounting base, a connecting rod, and a damping structure. When the support frame rotates, the first mounting base drives the damping shaft to rotate relative to the damping bushing. Compared with the existing complex mechanical structure, this structure reduces the links between components that affect each other, making the support frame rotate smoothly and avoiding the rotation interference problem caused by the existing complex mechanical structure. 2. The design of the first receiving groove, the second receiving groove, and the third receiving groove makes it easy for the rotating structure to be hidden in the placement groove when the support frame is closed. The top of the rotating structure can be basically flush with the phone case. The structural design of the phone case and the support frame meets the current demand for thinner and lighter phone cases. 3. The support frame is rotatably mounted in the placement slot of the phone case via a rotating structure. Only the first mounting base is directly rotatably connected to the support frame, which allows the support frame to rotate at the maximum angle relative to the phone case. This avoids the problem in existing brackets where the first mounting base is rotatably connected to two parts at the same time, and the rotation of the two parts may cause interference and limit the angle. The phone bracket of this application can meet the angle adjustment requirements of electronic devices from 0° to 180°, improving the practicality of the device and user satisfaction.

[0010] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0011] This application provides a mobile phone holder, which is described in the following embodiments. Figure 1 The device includes a phone case 1, a rotating structure 2, and a support frame 3, wherein the support frame 3 is rotatably mounted on the back of the phone case 1 via the rotating structure 2.

[0012] Specifically, in this embodiment, the back of the phone case 1 is provided with a circular groove 11, which is specifically used to accommodate the rotating structure 2 and the circular support frame 3. The shape and size of the groove 11 are carefully designed to fit the rotating structure 2 and the support frame 3, thus ensuring that the rotating structure 2 and the support frame 3 can rotate and move normally within the groove 11. The phone case 1 has recessed holes to expose the phone's camera and various buttons. The phone case 1 can be made of materials such as plastic and silicone. Plastic has a certain strength and toughness, while silicone has good flexibility. Both materials have a certain degree of wear resistance, which can protect the phone.

[0013] Specifically, the edge of the annular support frame 3 in this embodiment is provided with a notch 32 that allows the user to insert their hand. When the support frame 3 is needed, the user can pull the support frame 3 out of the placement slot 11 by inserting their finger into the notch 32.

[0014] Reference Figure 2 and Figure 3 Specifically, in this embodiment, the rotating structure 2 consists of a first mounting base 21 for connecting the support frame 3, a second mounting base 22 for connecting the phone case 1, two connecting rods 23, a damping structure 24, a third mounting base 25, and an elastic clamping seat 26. The damping structure 24 includes a damping bushing 241 and a damping shaft 242. The various structures cooperate with each other to realize the function of flexible rotation and angle adjustment of the support frame 3. Moreover, the structure is simple, avoids rotational interference, and improves the smoothness of rotation.

[0015] The primary function of the first mounting base 21 is to connect the support frame 3 and other parts of the rotating structure 2, providing excellent connection performance and stability. Its structural features include the ability to design its shape according to actual needs, such as square or round shapes, and to use high-strength plastics or metals, such as aluminum alloy, which is both lightweight and robust.

[0016] Specifically, the first mounting base 21 has a damping groove 211 on the side near the damping shaft 242. The damping shaft 242 is inserted into the damping groove 211 and forms an interference fit with the first mounting base 21 for a fixed connection. This connection method allows the damping shaft 242 to move synchronously with the first mounting base 21, ensuring stability during rotation. A connecting shaft 212 extends from the side of the first mounting base 21 near the connecting rod 23. The connecting shaft 212 passes through the end of the connecting rod 23 and is rotatably connected to it. The connecting shaft 212 is typically cylindrical, and its surface can be smoothed to reduce friction with the connecting rod 23 and improve the smoothness of rotation. The material of the connecting shaft 212 can be the same as that of the first mounting base 21, or other wear-resistant materials such as stainless steel can be used. During installation, the connecting shaft 212 must be able to rotate freely at the end of the connecting rod 23 without any jamming.

[0017] Reference Figure 4 The second mounting base 22 is used to connect with the phone case 1. Its shape and size need to match the phone case 1 to ensure a firm installation. The side of the second mounting base 22 away from the cutout area 31 has a first receiving groove 221, and the top of the second mounting base 22 has a second receiving groove 222. When the support frame 3 is closed, the damping structure 24 is located within the first receiving groove 221, and the connecting rod 23 is located within the second receiving groove 222. The function of the first receiving groove 221 is to accommodate the damping structure 24, preventing it from protruding when the support frame 3 is closed, thus affecting the overall aesthetics and usability. The design of the second receiving groove 222 is also for accommodating the connecting rod 23, making the support frame 3 more compact when closed. The shape and size of the first receiving groove 221 need to be designed according to the shape and size of the damping structure 24 to ensure that the damping structure 24 can be fully accommodated. The depth and width of the second receiving groove 222 need to be determined according to the diameter and length of the connecting rod 23 to ensure that the connecting rod 23 can be placed stably within it.

[0018] Specifically, an arc-shaped transition portion 243 is formed between the damping bushing 241 and the extension 244. The damping bushing 241 is fitted onto the damping shaft 242, and its bottom extends downward to form the extension 244, which is rotatably connected to the second mounting base 22. The fit between the damping bushing 241 and the damping shaft 242 generates a damping force, giving the support frame 3 a certain resistance during rotation, thereby achieving stable angle adjustment. The arc-shaped transition portion 243 is recessed towards the first receiving groove 221. The design of the arc-shaped transition portion 243 can reduce interference of the damping structure 24 during rotation and improve the smoothness of rotation.

[0019] Reference Figure 5Furthermore, a third receiving groove 245 is provided on the side of the arc-shaped transition portion 243 away from the first receiving groove 221. When the support frame 3 is closed, the first mounting seat 21 is located within the third receiving groove 245. The function of the third receiving groove 245 is to accommodate the first mounting seat 21, further improving the compactness of the support frame 3 when closed. The shape and size of the third receiving groove 245 must be adapted to the first mounting seat 21 to ensure that the first mounting seat 21 can fit tightly within it.

[0020] The connecting rod 23 serves to connect the first mounting base 21 and the second mounting base 22. Its length and diameter need to be determined according to the actual design requirements. The connecting rod 23 can be made of metal or plastic, such as stainless steel, which has high strength and corrosion resistance. Both ends of the connecting rod 23 are rotatably connected to the connecting shaft 212 of the first mounting base 21 and the second mounting base 22, respectively, allowing the support frame 3 to rotate around the rotating structure 2. During rotation, the connecting rod 23 must be able to rotate flexibly with the relative positions of the first mounting base 21 and the second mounting base 22 to achieve angle adjustment of the support frame 3. Specifically, both connecting rods 23 have an arc-shaped bottom design to match the second receiving groove 222.

[0021] The connecting rod 23 is rotatably connected to the second mounting base 22 via the first rotating shaft 27, and the extension 244 is rotatably connected to the second mounting base 22 via the second rotating shaft 28. The third mounting base 25 is located at the bottom of the second mounting base 22, and is rotatably connected to both the first rotating shaft 27 and the second rotating shaft 28. The function of the third mounting base 25 is to enhance the stability of the rotating structure 2, making the connecting rod 23 and the extension 244 more stable during rotation.

[0022] Specifically, the second mounting base 22 has a limiting post at its bottom, and the third mounting base 25 has a limiting hole 251 that engages with the limiting post. The engagement between the limiting post and the limiting hole 251 restricts the position of the third mounting base 25, preventing it from shifting during rotation. The size and shape of the limiting post must match the limiting hole 251 to ensure a tight fit and effective limiting function.

[0023] The second mounting base 22 has a groove 223 on its outer wall, and an elastic locking seat 26 is embedded between the groove wall of the groove 223 and the placement groove 11. The function of the elastic locking seat 26 is to fix the rotating structure 2 in the placement groove 11 of the phone case 1, preventing the rotating structure 2 from loosening during use. The elastic locking seat 26 can be made of elastic materials such as rubber, which have good elasticity and friction. When installing the elastic locking seat 26, it is necessary to ensure that it can be tightly embedded between the groove 223 and the placement groove 11, providing sufficient locking force.

[0024] The following explains in detail the principle of rotation and the positional relationships between the various structures in the closed and open states: Closed state: Refer to Figure 5 The support frame 3 is fitted inside the placement groove 11. The first mounting base 21 is located inside the third receiving groove 245 and fits tightly against it. The damping structure 24 is located inside the first receiving groove 221, and the connecting rod 23 is located inside the second receiving groove 222. The damping shaft 242 extends into the damping groove 211 of the first mounting base 21, and the damping bushing 241 is fitted onto the damping shaft 242. The bottom extension 244 is rotatably connected to the second mounting base 22, and the arc-shaped transition portion 243 is recessed towards the first receiving groove 221. The arc-shaped design of the bottom of the connecting rod 23 matches the second receiving groove 222, allowing it to be placed stably within it.

[0025] Open status: See Figure 4 The support frame 3 is pulled out from the placement slot 11 and is in an unfolded, supportable state. The damping groove 211 of the first mounting base 21 is fixed to the damping shaft 242 with an interference fit. The connecting shaft 212 passes through the end of the connecting rod 23 and is rotatably connected to it. The damping structure 24 is located outside the first receiving slot 221, and the connecting rod 23 is located outside the second receiving slot 222. The damping shaft 242 extends into the damping groove 211 of the first mounting base 21, and the damping bushing 241 is fitted onto the damping shaft 242. The bottom extension 244 is rotatably connected to the second mounting base 22. The arc-shaped transition part 243 is recessed towards the first receiving slot 221, and the third receiving slot 245 is exposed and does not accommodate the first mounting base 21. The arc-shaped design at the bottom of the connecting rod 23 does not contact the second receiving slot 222 and rotates with the relative positions of the first and second mounting bases to achieve angle adjustment of the support frame 3.

[0026] The implementation principle of this embodiment is as follows: The rotating structure 2 consists of a first mounting base 21, a second mounting base 22, two connecting rods 23, a damping structure 24, a third mounting base 25, and an elastic clamping seat 26. The damping structure 24 generates damping force, making the rotation of the support frame 3 subject to resistance, thus achieving stable angle adjustment. The first mounting base 21 connects to the support frame 3 and is rotatably connected to the connecting rods 23 via a connecting shaft 212; the second mounting base 22 connects to the phone case 1 and has first and second receiving slots 221 and 222 respectively to accommodate the damping structure 24 and the connecting rods 23; the connecting rods 23 connect the first and second mounting bases 21 and 22; the third mounting base 25 enhances the stability of the rotating structure 2 and is limited to the second mounting base 22 via a limiting post and a limiting hole 251; the elastic clamping seat 26 fixes the rotating structure 2 in the placement slot 11 of the phone case 1. Through the cooperation of each structure, the support frame 3 can rotate flexibly and its angle can be adjusted, while avoiding rotational interference and improving the smoothness of rotation.

[0027] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
