Description

Technical Field

[0001] This utility model relates to the field of electronic accessories technology, specifically to a mobile terminal support device. Background Technology

[0002] With the increasing prevalence of modern electronic devices, users' demand for convenient and efficient device support is also growing. Especially with the continuous enhancement of the functions of portable electronic terminals such as smartphones and tablets and the diversification of application scenarios, people not only need a support that can stably support these devices, but also one that is easy to carry and allows for easy adjustment of the viewing angle. Traditional ring supports often lack flexibility and cannot be adjusted in angle when supporting electronic devices.

[0003] This limitation requires users to exert considerable effort when adjusting their grip posture or encountering scenarios that require flexible changes in perspective. Therefore, a rotating ring support has been designed, such as the patent with publication number CN222321927U, publication date January 7, 2025, entitled "A Support Assembly," which discloses a turntable rotatably disposed in a mounting groove. The turntable includes a snap-fit ​​part and a connecting part, and the support frame is connected to the connecting part. However, since the support frame is applied to the back panel of the phone case, the support frame often still works normally when the phone case becomes old, but the user must replace both the back panel and the support frame.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0043] Please refer to Figures 1 to 2As shown, this embodiment provides a mobile terminal support device 100, which includes: a main body 110, a support component 111, a first rotating component 112, and a second rotating component 113; wherein, the main body 110 includes a magnetic component 1101, and the main body 110 can be attracted to a mobile terminal or mobile terminal accessory by the magnetic force of the magnetic component 1101; the first rotating component 112 is rotatably disposed on the main body 110, the second rotating component 113 is rotatably connected to the first rotating component 112, and the support component 111 is connected to the second rotating component 113; when the first rotating component 112 rotates, it can cause the support component 111 to rotate relative to the main body 110; when the second rotating component 113 rotates around the first rotating component 112, it can cause the support component 111 to move closer to or further away from the main body 110.

[0044] According to the above scheme, it can be understood that this embodiment achieves secure adsorption with the mobile terminal or its accessories through the magnetic force of the magnetic component 1101, which not only ensures the stability of the connection, but also simplifies the installation process; and, through the first rotating component 112 and the second rotating component 113, the dual rotation mechanism of the support component 111 is realized, so that the support component 111 can be adjusted in all directions relative to the main body 110 with the first rotating component 112, and can move closer to or away from the main body 110 under the action of the second rotating component 113.

[0045] Specifically, when the first rotating component 112 rotates, it drives the second rotating component 113 to rotate, and the rotation of the second rotating component 113 in turn drives the support component 111 to rotate together. In another application, when the second rotating component 113 rotates, the first rotating component 112 does not rotate, and the second rotating component 113 drives the support component 111 to rotate. It can be understood that this structure enriches the range of choices for support angle and position, meeting the user's needs in different scenarios; it avoids the problem of insufficient flexibility in traditional ring supports and solves the problem of unstable support that may occur when the support frame rotates around the base. By precisely controlling the motion relationship between the two rotating components, the support device 100 can maintain a stable support effect while ensuring flexible adjustment, effectively preventing the risk of damage to electronic devices caused by unstable support, and providing users with a safer and more reliable solution.

[0046] According to the above scheme, it can be understood that in this embodiment, the main body 110 can be attracted to the mobile terminal or mobile terminal accessory by the magnetic force of the magnetic component 1101. The mobile terminal in this embodiment can be a mobile phone, tablet or other electronic products, while the mobile terminal accessory can be a mobile phone case made of metal or other protective cases made of metal, which are not limited here.

[0047] Please refer to Figures 1 to 2 and Figure 6As shown, preferably, in some embodiments, the main body 110 includes a mounting groove 110a, and the first rotating component 112 is rotatably disposed in the mounting groove 110a; specifically, the structure of the mounting groove 110a matches the size and shape of the first rotating component 112 to ensure a tight fit between the two; optionally, in this embodiment, the groove wall of the mounting groove 110a is designed as an arc-shaped guide surface structure, which can help the first rotating component 112 maintain the correct path when rotating, prevent deviation or jamming, thereby improving the efficiency of rotation adjustment and user experience.

[0048] Please refer to Figures 1 to 2 As shown, optionally, in other embodiments, the main body 110 may also be designed with other structures for the user to install the first rotating component 112, such as installing the first rotating component 112 on the top of one end of the main body 110, or installing the first rotating component 112 on the bottom of one end of the main body 110. This embodiment does not limit this.

[0049] Please refer to Figure 7 and Figure 11 As shown, specifically, the first rotating assembly 112 includes a turntable 1121, which has a locking portion 1221. A protrusion 1102 is provided on the side wall of the mounting groove 110a, and a locking groove 110b is formed between the protrusion 1102 and the bottom of the mounting groove 110a. At least a portion of the locking portion 1221 is placed in and movable relative to the locking groove 110b. Specifically, this structural design enables the turntable 1121 to rotate smoothly and accurately 360 degrees, while the locking portion 1221... The engagement between the mounting slot 110a and the locking groove 110b provides a stable positioning point for the turntable 1121. When the user adjusts the support angle, the turntable 1121 can rotate freely within the mounting slot 110a, while the locking part 1221 slides within the locking groove 110b, thus ensuring smooth rotation operation. At the same time, due to the tight engagement between the locking part 1221 and the locking groove 110b, even under external force, the turntable 1121 will not easily undergo unnecessary displacement or loosening, enhancing the safety of the device.

[0050] Please refer to Figures 6 to 7 and Figure 11As shown, preferably, the second rotating component 113 includes a fixing member 1131, which is provided with a connecting sleeve 1231. The first rotating component 112 also includes a connecting shaft 1222 fixedly connected to the turntable 1121. The connecting sleeve 1231 is sleeved on the outside of the connecting shaft 1222 and pivotally connected to the connecting shaft 1222, thereby realizing the rotation of the second rotating component 113 relative to the first rotating component 112. It can be understood that the core of this design is to ensure that the second rotating component 113 can be adjusted at multiple angles around the first rotating component 112 while maintaining a stable connection between the two. When the user needs to adjust the support angle, the connecting sleeve 1231 can rotate freely on the connecting shaft 1222, so that the end of the support component 111 (usually a support ring 1111 or other forms of support structure) away from the connection to the connecting shaft 1222 can move closer to or further away from the main body 110, thereby adapting to different usage scenarios and needs. More importantly, since the connecting sleeve 1231 and the connecting shaft 1222 adopt a pivotal connection, this not only ensures the smoothness of the rotation operation, but also allows for appropriate resistance at a specific angle, preventing the support assembly 111 from being accidentally displaced by external forces, thus enhancing the safety of use.

[0051] Optionally, the connecting shaft 1222 passes through the center of the first rotating assembly 112 (particularly the turntable 1121).

[0052] In this embodiment, the connecting shaft 1222 is designed to pass through the center of the first rotating component 112 (particularly the turntable 1121). This design ensures that when the second rotating component 113 is rotated relative to the first rotating component 112, the center of rotation is close to the connection end of the connecting shaft 1222 and the support component 111, resulting in high consistency and stability in the relative movement between the second rotating component 113 and the first rotating component 112. Conversely, if the connecting shaft 1222 is not designed to pass through the center of the first rotating component 112, meaning the center of rotation of the first rotating component 112 is far from the connection point of the connecting shaft 1222 and the first rotating component, this eccentric arrangement will introduce additional mechanical stress, potentially leading to excessive wear between components and instability during rotation. Furthermore, uneven resistance changes may occur when adjusting the support angle, affecting the user experience. Moreover, the unbalanced force caused by asymmetry may cause unnecessary vibration or displacement, reducing the overall safety and reliability of the device.

[0053] Based on the above design, it is understandable that the design of the connecting shaft 1222 and the connecting sleeve 1231 takes into account the durability and ease of maintenance for long-term use. The connecting shaft 1222 may be made of high-strength material to withstand the mechanical stress caused by repeated rotation, while the connecting sleeve 1231 may have a wear-resistant layer or lubrication structure inside to reduce frictional loss and extend its service life.

[0054] Please refer to Figure 6 and Figure 11 As shown, preferably, the fixing member 1131 is further provided with a snap-fit ​​plate 1232, which is located at the other end of the fixing member 1131 away from the connecting sleeve 1231; the support assembly 111 includes a support ring 1111, which is detachably assembled to the snap-fit ​​plate 1232; it can be understood that this structural design not only optimizes the connection relationship between internal components, but also provides the convenience of easy installation and disassembly of the external support assembly 111. In this solution, the design of the snap-fit ​​plate 1232 is the key to this improvement. Since the support ring 1111 adopts a detachable design, this provides users with a A flexible selection space: Users can replace the support ring 1111 with different sizes, colors, or shapes according to personal preferences or different scenario needs. They can even completely remove it when the support function is not needed, restoring the device to its original state, thereby meeting different user needs. In addition, when the support ring 1111 wears or is damaged due to long-term use, users can easily replace the new part without having to replace the entire support device 100, reducing maintenance costs. Moreover, the detachable support ring 1111 design also facilitates product cleaning and maintenance, preventing the accumulation of dust and dirt from affecting the device's performance.

[0055] Please refer to Figure 7 and Figure 12 As shown, preferably, as the mounting component of the support ring 1111, the support ring 1111 is quickly assembled and disassembled through a specific snap-fit ​​mechanism. In this embodiment, one end of the support ring 1111 is provided with multiple snap-fit ​​posts 1211, and the snap-fit ​​plate 1232 is provided with a connecting groove 123a. Each snap-fit ​​post 1211 can be detachably assembled into a connecting groove 123a. When the user assembles the support ring 1111 onto the snap-fit ​​plate 1232, he only needs to gently align the position and apply appropriate pressure. The snap-fit ​​post 1211 can then smoothly slide into the corresponding connecting groove 123a and be fixed through slight elastic deformation or interference fit. This design ensures that even if external vibration or impact occurs during use, the support ring 1111 will not easily fall off.

[0056] Please refer to Figures 3 to 5As shown, preferably, the main body 110 further includes a first groove 110c, at least a portion of which forms a communicating space 110d with the mounting groove 110a. When the support component 111 is housed in the first groove 110c, it is connected to the second rotating component 113 through the communicating space 110d. It can be understood that the main purpose of this design is to solve the problem of minimizing the space occupied by the support device 100 in the non-use state, while ensuring that the support component 111 can be quickly deployed at any time. When the user does not need to use the support function, the support ring 1111 can be housed in the first groove 110c. Since there is a communicating space 110d between the first groove 110c and the mounting groove 110a, even if the support component 111 is in the housed state, it can still maintain a connection with the second rotating component 113 through this communicating space 110d. This reduces the space occupied by the connection between the support ring 1111 and the connecting shaft 1222. The user can hide the support component 111 without completely disassembling it, which simplifies the operation steps and protects the components from the influence of the external environment.

[0057] Please refer to Figures 2 to 7 As shown, preferably, in some embodiments, the first rotating assembly 112 further includes a fastener 1122, which includes a limiting member 11221 and a spring 11222. One end of the spring 11222 abuts against the inner wall of the turntable 1121, and the other end abuts against and presses against the limiting member 11221. The back side of the limiting member 11221 that abuts against the spring 11222 abuts against at least a portion of the mounting groove 110a and generates an interaction force. This design not only enhances the stability of the turntable 1121 during rotation, It also provides users with a controllable damping effect, making rotational operation smooth yet with a certain sense of positioning. Specifically, when the user rotates the support device 100, the limiting member 11221 generates friction with the side wall or bottom of the mounting groove 110a under the pressure of the spring 11222. This friction provides the necessary resistance to prevent the turntable 1121 from rotating arbitrarily without external force, while allowing the user to easily adjust the angle as needed. Furthermore, the design of the limiting member 11221 is also indispensable. As the direct contact point between the fastener 1122 and the mounting groove 110a, its shape and material selection have been optimized to ensure optimal friction performance and durability. The contact between the back of the limiting member 11221 and the mounting groove 110a forms a stable support surface, maintaining a reliable connection even under prolonged use or external impact. Moreover, this design helps reduce wear caused by long-term use, extending the product's service life.

[0058] like Figure 7As shown, preferably, the mounting groove 110a also includes at least one alignment groove 1101a corresponding to the limiting member 11221. Optionally, this embodiment provides four alignment grooves 1101a, which are respectively located on the periphery of the mounting groove 110a and the distance between any two adjacent grooves is equal. The limiting member 11221 can be engaged in any one of the alignment grooves 1101a when rotating with the turntable 1121 by the elastic force applied by the spring 11222. It can be understood that this design not only enhances the stability and controllability of the rotation operation, but also provides the user with clear positioning feedback, ensuring that the turntable 1121 can find a suitable positioning point at different rotation angles. The limiting member 11221 is part of the fastener 1122, and it always maintains the tendency to contact the alignment groove 1101a through the continuous elastic force provided by the spring 11222. When the user adjusts the angle of the support device 100, the limiting member 11221 rotates with the turntable 1121 and automatically engages in each alignment slot 1101a. Due to the pressure of the spring 11222, the limiting member 11221 can be firmly embedded in the alignment slot 1101a, thereby fixing the position of the turntable 1121 and preventing unnecessary movement due to slight external vibrations or external forces. From the perspective of user experience, the direct benefit of this mechanism is that it provides a noticeable "click" or "clunk" sensation when the user adjusts the support angle. That is, whenever the limiting member 11221 engages in a new alignment slot 1101a, the user will feel a slight change in resistance. This not only helps the user accurately find the required support angle but also provides psychological satisfaction.

[0059] Please refer to Figures 2 to 5 and Figures 8 to 11 As shown, preferably, in some other embodiments, the first rotating assembly 112 further includes a fastener 1122, which includes a spring piece 12223 and a ball 12231 disposed on the spring piece 12223. The number of balls 12231 is set to at least one. The mounting groove also includes at least one locking groove 110g corresponding to the ball. The ball can rotate with the spring piece and be locked into any locking groove 110g. This design provides another implementation method for damping the turntable 1121. Compared with the previous embodiment, the difference is that the alignment groove 1101a in the previous embodiment is disposed on the periphery of the mounting groove, while the locking groove 110g in this embodiment is disposed on the inner wall of the housing of the main body 110. Figure 10As shown, the spring piece 12223 rotates along with the turntable 1121, causing the ball 12223 to rotate as well. This allows the ball 12223 to engage with one of the slots 110g during rotation. In this embodiment, there are four slots 110g. Two balls 12231 extend beyond the spring piece 12223, with opposite directions of extension. When one ball 12231 engages with one slot 110g, the other ball 12231 engages with the other slot 110g. This structure simultaneously engages two... The engagement of the ball 12231 enhances its damping effect on the turntable, making the rotation operation smooth and providing a certain sense of positioning. Specifically, when the user rotates the support device 100, the ball 12231 engages with the locking groove 110g on the inner wall of the upper shell of the main body 110 as the spring piece 12223 rotates with the turntable. This engagement provides necessary resistance, preventing the turntable 1121 from rotating arbitrarily without external force, while allowing the user to easily adjust the angle as needed. Furthermore, the design of the ball 12231 on the spring piece 12223 is also an indispensable part.

[0060] According to the above scheme, such as Figure 10 As shown, in another embodiment, the number of marbles 12231 can be set to 1. When marble 12231 is inserted into one of the slots 110g, it acts as a damper for the turntable, making the rotation operation smooth and with a certain sense of positioning.

[0061] Optionally, in other embodiments, the number of alignment slots 1101a may be set to six or other numbers, which is not limited in this application.

[0062] Please refer to Figures 1 to 4 and Figure 6 As shown, preferably, it also includes an elastic ring assembly 114, which includes a connecting ring 1141 and an elastic ring. The main body 110 also includes an inwardly circumferentially formed opening 110e. The connecting ring 1141 engages with the side wall of the main body 110 facing the opening 110e within the opening 110e. At least a portion of the elastic ring engages with the connecting ring 1141. The elastic ring can rotate relative to the connecting ring, enabling the elastic ring to be pulled outward from the opening 110e. This design not only provides users with a convenient additional function but also enhances the overall practicality and aesthetics of the product. Specifically, the main function of the elastic ring assembly 114 is to provide a flexible and retractable fixing or carrying method. This engagement mechanism ensures that the connecting ring 1141 will not easily loosen during use, while also facilitating installation and disassembly, allowing users to quickly adjust or replace the elastic ring as needed.

[0063] The elastic ring itself is made of highly elastic and wear-resistant silicone material, which can be easily pulled out and extended from the opening 110e to slip a finger into it, making it easier to hold electronic products such as mobile phones; when not in use, the elastic ring can retract back into the opening 110e to keep the device's appearance neat and compact.

[0064] According to the above scheme, specifically, this embodiment designs a double-layer structure composed of a first elastic ring 1142 and a second elastic ring 1143. The first elastic ring 1142 has a connecting groove 114a on the side facing the connecting ring 1141. At least a portion of the first elastic ring 1142 is connected to the connecting ring 1141 through the connecting groove 114a, and at least a portion of the second elastic ring 1143 is connected to the first elastic ring 1142, forming a cooperating whole. It can be understood that this double-layer elastic ring design helps to distribute the force and improve the stability of the overall structure. When the user stretches the elastic ring, the force will be evenly distributed between the first elastic ring 1142 and the second elastic ring 1143, reducing the pressure on individual components and thus extending the service life of the product. Furthermore, since the two elastic rings are connected to each other, they can naturally shrink together when not in use, without appearing messy, maintaining the neat appearance of the support device 100.

[0065] In summary, this utility model provides a mobile terminal support device that uses the magnetic force of a magnetic component to achieve secure adsorption with a mobile terminal or its accessories, ensuring a stable connection and simplifying the installation process. Furthermore, the dual rotation mechanism of the support component, achieved through the first and second rotating components, allows the support component to be adjusted omnidirectionally relative to the main body with the first rotating component, and to move closer to or away from the main body under the action of the second rotating component. This enriches the range of choices for the support angle and position, and it can be easily removed from the protective case, so that users do not need to replace the support device when changing the protective case, thus meeting the user's needs in different scenarios.

[0066] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
