Description

Technical Field

[0001] This utility model relates to the field of mobile phone stands, specifically to a double-folding ring rotating stand. Background Technology

[0002] With the widespread adoption of smartphones, the mobile phone accessory market is booming, and ring-shaped phone cases have become a popular product among consumers due to their convenience. They not only effectively prevent phones from accidentally slipping during use but also function as phone stands, providing users with a diverse user experience. However, existing ring-shaped phone cases have significant limitations: when used as phone stands, their small size results in a small angle between the phone and the horizontal plane when vertically supporting the phone. This forces users to frequently look down or adjust their viewing angle, easily causing neck fatigue over prolonged use and resulting in a poor viewing experience. Utility Model Content

[0003] In view of the above, the purpose of this utility model is to provide a solution to the problems of the prior art.

[0004] One type of double-folding ring rotating bracket in this solution includes:

[0005] Phone cases;

[0006] The base is fixedly attached to the back of the phone case;

[0007] The main support ring is rotatably connected to the base;

[0008] An auxiliary support ring is rotatably connected to the main support ring;

[0009] The double-folding ring rotating bracket has a stowed state, a first unfolded state, and a second unfolded state;

[0010] In the stowed state, the main support ring rotates relative to the base and is stowed in the base, while the auxiliary support ring rotates relative to the main support ring and is stowed in the inner contour of the main support ring;

[0011] In the first unfolded state, the main support ring rotates and unfolds relative to the base, while the auxiliary support ring remains in a retracted state relative to the main support ring.

[0012] The second unfolded state is based on the first unfolded state, in which the auxiliary support ring rotates and unfolds relative to the main support ring.

[0013] Furthermore, the main support ring is rotatably connected to the base via a first hinge, the first hinge including a base, a first rotating shaft, and a connecting piece, the base being connected to the base; the first rotating shaft is mounted on the base, one end of the connecting piece is connected to the first rotating shaft, and the other end of the connecting piece is connected to the main support ring.

[0014] Furthermore, the base is provided with mounting holes corresponding to the position of the base, and the base has a stepped structure, with part of the base embedded in the mounting holes and part of it located outside the mounting holes; a clamping piece is provided on the rear side of the base, and the base is clamped and fixed to the base by the clamping piece, and after being fixed, the base can rotate around the axis of the mounting holes.

[0015] Furthermore, the auxiliary support ring and the main support ring are rotatably connected by a second hinge, which is a second rotating shaft. The second rotating shaft is inserted into the rotating shaft hole of the auxiliary support ring and the main support ring and forms an interference fit.

[0016] Beneficial effects: The double-folding ring rotating bracket of this application achieves flexible adjustment at multiple angles through a dual-degree-of-freedom rotation design and a double-folding structure. It not only solves the problem of small vertical screen support angle and easy neck fatigue caused by traditional brackets, but also provides stable support when the screen is horizontal.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1 to 11 The double-folding ring rotating bracket shown is characterized by comprising a phone case 1, a base 2, a main support ring 3, and an auxiliary support ring 4.

[0026] The base 2 serves as the connecting hub between the stand and the phone case 1. Its design allows it to be securely attached to the back of the phone case 1 via adhesive. This design provides greater flexibility, enabling it to be sold as a standalone accessory, compatible with most phone cases 1 on the market, and meeting the personalized needs of different users. From an aesthetic perspective, a phone case 1 can also be specially designed to match the base 2, with a pre-drilled groove on the back. When the main support ring 3 and auxiliary support ring 4 are in their retracted state, they can be fully embedded in the groove, keeping the phone's appearance flat and smooth, maintaining both aesthetics and portability.

[0027] The main support ring 3 and the base 2 are rotatably connected via a first hinge. The first hinge consists of a base 5, a first rotating shaft 6, and a connecting piece 7. The base 5 serves as the mounting carrier for the first rotating shaft 6, providing a stable foundation for the entire rotating structure; the connecting piece 7 acts as a bridge, connecting the first rotating shaft 6 to the main support ring 3. More specifically, a ring of protrusions 601 is arranged around the outer wall of the first rotating shaft 6. The presence of these protrusions 601 significantly increases the friction on the surface of the rotating shaft. When the user applies external force to rotate the main support ring 3, the first rotating shaft 6 can rotate smoothly. Once the external force disappears, relying on the friction generated by the protrusions 601, the first rotating shaft 6 can quickly be fixed at the desired angle, ensuring the main support ring 3 is stably supported. Furthermore, the rotating shaft hole on the connecting piece 7 adopts an irregular design, with a matching irregular surface on the first rotating shaft 6. This prevents the connecting piece 7 from rotating relative to the first rotating shaft 6, further improving the overall structural stability.

[0028] The base 5 and the base 2 also form a rotational fit, a design that gives the bracket two degrees of rotational freedom. Specifically, the base 2 has a mounting hole 201 corresponding to the position of the base 5, and a clamping piece 8 is mounted on the rear side of the base 5, which has a stepped structure. During installation, part of the base 5 is inserted into the mounting hole 201, while the other part is blocked outside the mounting hole 201. The clamping piece 8, which is larger than the mounting hole 201, connects to the base 5 from another direction of the mounting hole 201, thereby clamping the base 2 with the base 5 and the clamping piece 8, firmly fixing the base 5 in the mounting hole 201 while allowing the base 5 to rotate freely within the mounting hole 201. In addition, the inner wall of the mounting hole 201 is provided with a toothed ring 202, and the base 5 is provided with a spring clip 501 that mates with it. When the user rotates the base 5, the spring clip 501 slides between the teeth of the toothed ring 202. After rotating to the appropriate angle and the external force disappears, the spring clip 501 will lock between two adjacent teeth to achieve precise angle fixation and meet the diverse needs of users for the bracket angle in different usage scenarios.

[0029] The auxiliary support ring 4 is rotatably connected to the main support ring 3 via a second hinge. The second hinge employs a simple and efficient second rotating shaft (not shown in the figure), which is inserted into pre-drilled rotating shaft holes in both the auxiliary support ring 4 and the main support ring 3, forming an interference fit with the holes. This fit allows the auxiliary support ring 4 to be fixed at any angle during rotation by relying on the friction between the rotating shaft and the holes, making operation simple, stable, and reliable.

[0030] The double-folding ring rotating stand has three different modes: a stowed state, a first unfolded state, and a second unfolded state. Each mode corresponds to a specific usage scenario.

[0031] In its stowed state, the main support ring 3 rotates relative to the base 2 and is stored within the base 2. At the same time, the auxiliary support ring 4 also rotates relative to the main support ring 3 and is stored within the inner contour of the main support ring 3. The entire bracket structure is compact and fits tightly with the phone case 1 without taking up extra space, making it convenient for users to put their phones in their pockets or backpacks, making it extremely easy to carry.

[0032] When in its first unfolded state, the main support ring 3 rotates and unfolds relative to the base 2 to a suitable angle, while the auxiliary support ring 4 remains in its retracted state. At this time, the main support ring 3 and the auxiliary support ring 4 together present a single-ring structure, and its function is similar to that of a traditional ring. In daily use, users can hold the phone by threading their fingers through the ring. The special texture design on the surface of the ring can significantly increase friction, providing a stable grip even in scenarios where the phone is prone to slipping, such as one-handed operation, walking, or exercise, effectively reducing the risk of accidental drops. At the same time, this single-ring structure can also serve as a simple stand, firmly supporting the phone on flat surfaces such as desktops and tabletops.

[0033] The second unfolded state is a further expansion based on the first unfolded state. The auxiliary support ring 4 rotates and unfolds relative to the main support ring 3, and its unfolding angle can be flexibly adjusted according to the user's actual needs. For example, when the auxiliary support ring 4 is unfolded to 90 degrees, the main support ring 3 and the auxiliary support ring 4 together form an L-shaped support arm. This structure can provide strong stability when the phone is in a landscape viewing position. If the auxiliary support ring 4 is unfolded to 180 degrees, the two will form a whole straight support arm. The length of this support arm is significantly increased compared to the support arm in the first unfolded state, which can effectively improve the support tilt angle between the phone and the horizontal plane when the phone is viewed in portrait mode, allowing users to comfortably view the screen content without looking down. Whether reading e-books, checking information, or watching live broadcasts, it can bring an excellent visual experience.

[0034] Furthermore, in both the first and second unfolded states, the stand can rotate around an axis perpendicular to the phone via the base 5. This feature provides users with more options and a wider range of adjustments during use.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
