Technical Field

[0001] This utility model relates to the technical field of openable and rotatable support mechanisms, specifically to an elastic wave-type openable and rotatable limiting support structure. Background Technology

[0002] With the advancement and development of technology, small electronic products such as mobile phones and tablets have become necessities in life. They not only meet users' communication needs but also provide social entertainment functions. To facilitate users' use of these electronic products on tables or other flat surfaces, openable support frames are designed on the back covers or back shells of these products. By manually opening the support frame, users can place the electronic products at a certain tilt angle on flat surfaces such as tables, chairs, and windowsills, making it convenient for users to watch videos, live streams, etc., thus improving the user experience.

[0003] Existing openable support frames can only be opened and closed, and electronic products can only be placed in a fixed direction when in use. When the user rotates the screen of the electronic product or supports it on an inclined table, the existing support frames can no longer meet the support needs, which limits their use, and the convenience and flexibility need to be improved, resulting in a poor user experience. Utility Model Content

[0004] To address the technical problem that existing support frames can only open and close but cannot rotate, resulting in poor user convenience and flexibility, this utility model provides an elastic wave-shaped opening, closing, rotating, and limiting support structure that can open, close, and rotate, flexibly adjusting direction and angle, effectively improving user convenience and flexibility.

[0005] The technical solution adopted by this utility model is to provide an elastic wave-type opening and closing rotation limiting support structure, including a shell, a mounting hole at the bottom of the shell, an annular protrusion on the inner wall of the mounting hole, a hinge seat inserted into the mounting hole, a support plate at the outer end of the hinge seat, a limiting annular groove at the inner end of the hinge seat, and a limiting seat at the inner end of the hinge seat; the inner end of the hinge seat is inserted into the mounting hole and the annular protrusion is embedded in the limiting annular groove, the limiting seat is fixed to the inner side of the shell and the inner end of the hinge seat, and the outer diameter of the limiting seat is larger than the inner diameter of the mounting hole.

[0006] It also includes a snap-fit ​​plate disposed in the limiting ring groove, a snap-fit ​​interface disposed on the limiting seat and corresponding to the snap-fit ​​plate, and a clearance opening disposed on the annular protrusion and corresponding to the snap-fit ​​plate. The width of the snap-fit ​​plate is smaller than the width of the clearance opening. One end of the snap-fit ​​plate is fixed in the limiting ring groove, and the other end passes vertically downward through the clearance opening of the annular protrusion and is inserted into the snap-fit ​​interface.

[0007] It also includes a positioning rod and a threaded hole located at the inner end of the hinge seat, a fixing hole located on the limit seat and corresponding to the positioning hole and the threaded hole, and a fastening bolt that passes through the fixing hole and is screwed into the threaded hole.

[0008] It also includes a damping column erected inside the housing and spaced apart from the limiting seat, a damping arc plate disposed between the limiting seat and the damping column, a connecting plate disposed between the damping arc plate and the limiting seat, and a stop protrusion disposed on the outer side of the other end of the damping arc plate; the damping arc plate is spaced apart from the outer periphery of the limiting seat, one end of the damping arc plate is fixed to the connecting plate on its inner side and the other end is suspended, and the damping column abuts against the outer side of the damping arc plate and the abutting position is located between the fixed end of the damping arc plate and the stop protrusion.

[0009] It also includes a hinge boss on the outer end of the hinge seat, a hinge interface on one side of the hinge boss, a hinge pin in the hinge interface, a hinge joint on one end of the support plate and embedded in the hinge interface, and a pin hole on the hinge joint that is adapted to the hinge pin; the hinge boss and the outer end face of the hinge seat form a stepped structure, the hinge joint is embedded in the hinge interface and fitted onto the hinge pin, and one end of the support plate is hinged to the hinge boss through the hinge joint, and the inner side of the end of the support plate abuts against the outer end face of the hinge seat.

Detailed Implementation

[0018] like Figure 1-5 As shown, this utility model provides an elastic wave-type opening and closing rotation limiting support structure, including a housing 1, a mounting hole 2 at the bottom of the housing 1, an annular protrusion 3 on the inner wall of the mounting hole 2, a hinge seat 4 inserted into the mounting hole 2, a support plate 5 at the outer end of the hinge seat 4, a limiting annular groove 6 at the inner end of the hinge seat 4, and a limiting seat 7 at the inner end of the hinge seat 4; the inner end of the hinge seat 4 is inserted into the mounting hole 2 and the annular protrusion 3 is embedded in the limiting annular groove 6, the limiting seat 7 is located inside the housing 1 and fixed to the inner end of the hinge seat 4, and the outer diameter of the limiting seat 7 is larger than the inner diameter of the mounting hole 2.

[0019] The structure of housing 1 is not limited; it can be the back cover or rear shell of an electronic product. Housing 1 has a mounting hole 2. An annular protrusion 3, forming a circular structure, is designed on the inner circumference (inner wall) of the mounting hole 2. The hinge seat 4 is circular and fits the inner diameter of the mounting hole 2. The inner end of the hinge seat 4 is inserted into the mounting hole 2 from the outside of housing 1. A limiting annular groove 6 is designed on the inner end of the hinge seat 4. After the hinge seat 4 is inserted, the annular protrusion 3 of the mounting hole 2 abuts against the limiting annular groove 6, limiting the hinge seat 4 and preventing it from passing directly through the mounting hole 2. The connector 4 can rotate within the mounting hole 2. The limiting seat 7 is also circular and located inside the housing 1, fixed to the inner end of the hinge seat 4. Since the outer diameter of the limiting seat 7 is larger than the inner diameter of the mounting hole 2, the hinge seat 4 is limited after the limiting seat 7 is fixed, so that the hinge seat 4 can only rotate within the mounting hole 2 and cannot detach from the mounting hole 2. The support plate 5 has a long strip-shaped structure, with one end hinged to the outer end of the hinge seat 4. In use, the support plate 5 can not only open and close, but also rotate, effectively improving the user's convenience and flexibility, and greatly enhancing the user experience.

[0020] like Figure 3-5As shown, it also includes a snap-fit ​​plate 8 disposed in the limiting ring groove 6, a snap-fit ​​interface 9 disposed on the limiting seat 7 and corresponding to the snap-fit ​​plate 8, and a clearance opening 10 disposed on the annular protrusion 3 and corresponding to the snap-fit ​​plate 8. The width of the snap-fit ​​plate 8 is smaller than the width of the clearance opening 10. One end of the snap-fit ​​plate 8 is fixed in the limiting ring groove 6, and the other end passes vertically downward through the clearance opening 10 of the annular protrusion 3 and is inserted into the snap-fit ​​interface 9.

[0021] This structure further improves the fixing method of the hinge seat 4 and the limiting seat 7, and can also further limit the rotation range of the support plate 5. The structure includes a snap-fit ​​plate 8, a snap-fit ​​interface 9, and a clearance opening 10. The snap-fit ​​plate 8 can be a columnar or plate-like structure, with one end fixed in the limiting annular groove 6, and the other end passing through the clearance opening of the annular protrusion 3 and inserted into the snap-fit ​​interface 9 of the limiting seat 7, thus connecting the hinge seat 4 and the limiting seat 7. This also allows for better control during user operation. When the support plate 5 rotates, the hinge seat 4 rotates synchronously within the mounting hole 2. At this time, the snap plate 8 makes a circular motion within the clearance opening 10. After the snap plate 8 abuts against the inner wall of the clearance opening 10 on one side, i.e., the end of the annular protrusion 3, the hinge seat 4 can no longer rotate and can only rotate in the opposite direction. By controlling the dimensions of the snap plate 8 and the clearance opening 10, the rotation range of the hinge seat 4 can be limited, i.e., the rotation range of the support plate 5 can be limited. The dimensions and quantity of the snap plate 8 and the clearance opening 10 can be selected according to requirements.

[0022] like Figure 4-5 As shown, it also includes a positioning rod 11 and a threaded hole 12 disposed at the inner end of the hinge seat 4, a positioning hole 13 disposed on the limit seat 7 and corresponding to the positioning rod 11 and the threaded hole 12, and a fastening bolt 15 passing through the fixing hole 14 and screwed into the threaded hole 12.

[0023] This structure further strengthens the connection between the hinge seat 4 and the limit seat 7. The positioning rod 11 and the positioning hole 13 can be positioned during assembly. The fastening bolt 15, the fixing hole 14 and the threaded hole 12 can further tighten the connection between the hinge seat 4 and the limit seat 7, making assembly more convenient and the connection strength higher.

[0024] like Figure 2 , 4 As shown in Figure 5, the device also includes a damping column 16 erected inside the housing 1 and spaced apart from the limiting seat 7, a damping arc plate 17 disposed between the limiting seat 7 and the damping column 16, a connecting plate 18 disposed between the damping arc plate 17 and the limiting seat 7, and a stop protrusion 19 disposed on the outer side of the other end of the damping arc plate 17; the damping arc plate 17 is spaced apart from the outer periphery of the limiting seat 7, one inner side of the damping arc plate 17 is fixed to the connecting plate 18 and the other end extends outward, the damping column 16 abuts against the outer side of the damping arc plate 17 and the abutting position is located between the fixed end of the damping arc plate 17 and the stop protrusion 19.

[0025] This structure dampens the rotation of the rotating seat 4. The shape of the damping arc plate 17 matches the circular trajectory of the rotating seat 4 during rotation. When the rotating seat 4 rotates within the mounting hole 2, the limiting seat 7 rotates synchronously, and the damping arc plate 17 on the limiting seat 7 rotates synchronously as well. The damping arc plate 17 abuts against the side of the damping column 16, generating friction between the damping arc plate 17 and the damping column 16, thus achieving a damping effect. This increases the force required to manually rotate the support plate 5 and effectively prevents the rotating seat 4 from rotating on its own within the mounting hole 2 when the housing 1 is not in operation, due to shaking or vibration. The size of the damping arc plate 17 and the abutting force against the damping column 16 can be adjusted according to requirements. The stop protrusion 19 on the damping arc plate 17 can further limit the rotation range, ensuring consistency with the rotation range of the snap-fit ​​plate 8 within the clearance opening 10.

[0026] like Figure 4-5 As shown, it also includes a hinge boss 20 disposed on the outer end of the hinge seat 4, a hinge interface 21 disposed on one side of the hinge boss 20, a hinge pin 22 disposed in the hinge interface 21, a hinge joint 23 disposed at one end of the support plate 5 and embedded in the hinge interface 21, and a pin hole 24 disposed on the hinge joint 23 and adapted to the hinge pin 22; the hinge boss 20 and the outer end face of the hinge seat 4 form a stepped structure, the hinge joint 23 is embedded in the hinge interface 21 and fitted onto the hinge pin 22, one end of the support plate 5 is hinged to the hinge boss 20 through the hinge joint 23 and the inner side of the end of the support plate 5 abuts against the outer end face of the hinge seat 4.

[0027] This structure is an improvement on the hinge structure between the hinge seat 4 and the support plate 5. One end of the support plate 5 is fitted onto the hinge pin 22 inside the hinge interface 21 through the hinge joint 23, and is hinged to the hinge seat 4. When the support plate 5 is closed, the lower end face of the support plate 5 will abut against the end face of the hinge seat 4 to achieve positioning and limiting. When the support plate 5 is opened, the end of the support plate 5 will open 90° and abut against the end face of the hinge boss 20 to achieve positioning and limiting. The support is more stable and more convenient for users.

[0028] like Figure 4-5 As shown, it also includes a positioning port 25 disposed on the outer end of the hinge seat 4 and corresponding to the hinge interface 21, a positioning spring plate 26 disposed in the positioning port 25, a limiting protrusion 27 disposed on the upper end surface of the positioning spring plate 26, and a positioning protrusion 28 disposed on the lower end surface of the hinge joint 23; one end of the positioning spring plate 26 is fixed to the inner wall of the positioning port 25, and the other end extends horizontally toward the hinge interface 21, and the positioning protrusion 28 of the hinge joint 23 corresponds to the outer side of the limiting protrusion 27 on the positioning spring plate 26.

[0029] This structure serves as a positioning mechanism for the opening and closing of the support plate 5. One end of the positioning spring plate 26 is fixed to the inner wall of the positioning port 25 on the side facing away from the hinge interface 21. The other end of the positioning spring plate 26, i.e., the end with the limiting protrusion 27, extends horizontally towards the hinge interface 21. After the support plate 5 is closed, the positioning protrusion 28 on the hinge joint 23 will abut against the limiting protrusion 27 when it passes the limiting protrusion 27. After the support plate 5 is closed and in place, the positioning protrusion 28 abuts against the side of the limiting protrusion 27 facing the hinge interface 21. The limiting protrusion 27 limits the positioning protrusion 28, i.e., limits the support plate 5. When opening the support plate 5, after the manual operation force is reached, the positioning protrusion 28 will press down the limiting protrusion 27 before the support plate 5 can be opened. The same principle applies when the support plate 5 is closed. This effectively prevents the support plate 5 from swinging and opening and closing when the housing 1 is shaken without manual operation, making it more convenient for users. The hinge seat 4, limit seat 7, snap plate 8, positioning rod 11, damping arc plate 17, connecting plate 18, stop protrusion 19, hinge boss 20, positioning spring plate 26, limit protrusion 27 and positioning protrusion 28 in this design are all made of plastic and have good elasticity.
