Description

Technical Field

[0001] This utility model relates to the field of screen support frame technology, specifically to a mobile phone stand structure with screen rotation capability. Background Technology

[0002] A screen rotating bracket, as the name suggests, is a screen support frame that allows for screen angle adjustment. Electric vehicle phone holders are one type. These rotating brackets typically include a bracket fixing mechanism, an angle adjustment mechanism, and a screen fixing mechanism. The bracket is fixed to the handlebars via the bracket fixing mechanism. The angle adjustment mechanism, located between the bracket fixing mechanism and the screen fixing mechanism, includes a support base, a spherical ball joint, a connecting block, and a threaded cap. The support base has a spherical groove on its end face and threads on its side end. The threaded cap engages with the threads on the support base, tightening to confine the spherical ball joint within the groove. The threaded cap has a through hole on its end face. One end of the connecting block is fixedly connected to the spherical ball joint, and the other end passes through the through hole and connects to the screen fixing mechanism. When the threaded cap is tightened, friction exists between the spherical groove and the spherical ball joint, allowing for direct screen fixation after angle adjustment. However, bumps during vehicle movement can cause the threaded cap to loosen, reducing friction between the spherical groove and the spherical ball joint, making it impossible to fix the screen angle. Frequent tightening of the threaded cap is necessary, which is inconvenient. Utility Model Content

[0003] The purpose of this invention is to overcome the technical defects of existing screen rotation brackets that are prone to loosening and require frequent tightening, and to provide a screen-rotating mobile phone bracket structure.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a screen-rotatable mobile phone stand structure, comprising a stand fixing mechanism, a screen fixing mechanism, a support base, a universal ball, a threaded cover, and a connecting block. The support base is fixedly connected to the stand fixing mechanism, and the connecting block is fixedly connected to the screen fixing mechanism. The end face of the support base has a groove that matches the universal ball. The threaded cover is threadedly connected to the end of the support base, limiting the universal ball within the groove and the threaded cover. The end face of the threaded cover has a through hole, through which the connecting block passes and is fixedly connected to the universal ball. The threaded cover has a limiting ring inside, and the universal ball is rotatably positioned within the limiting ring. The inner diameters at both ends of the limiting ring are smaller than the inner diameter of the middle section, preventing the universal ball from detaching from the limiting ring. The limiting ring slides axially within the threaded cover. A damping elastic component is fixedly provided at the end of the limiting ring, and the other end of the damping elastic component is fixedly connected to the inner wall of the threaded cover.

[0005] Furthermore, a ball bearing is embedded in the inner wall of the limiting ring, and the ball bearing rotates to be disposed inside the limiting ring, with the surface of the ball bearing in contact with the surface of the universal ball.

[0006] Furthermore, the threaded cover has a limiting sleeve corresponding to the limiting ring inside, and the limiting ring is slidably disposed inside the limiting sleeve.

[0007] Furthermore, the outer side of the limiting ring is provided with a limiting rib, and the inner wall of the limiting sleeve is provided with a corresponding limiting groove, and the limiting rib is slidably disposed in the limiting groove.

[0008] Furthermore, a resistance pad layer for increasing friction is provided on the inner wall of the groove.

[0009] Furthermore, a dustproof silicone sleeve is provided between the outer side of the threaded cover and the screen fixing mechanism, and the connecting block is located inside the dustproof silicone sleeve.

[0010] The beneficial effects of this utility model are as follows: This utility model uses a damping elastic component to connect a limiting ring, which presses the universal ball tightly against the inner wall of the groove. When encountering bumpy roads, the damping elastic component absorbs the vibration, preventing the vibration of the vehicle body from being transmitted to the universal ball and preventing loosening. A resistance pad is provided on the inner wall of the groove to increase the friction, thereby further preventing the universal ball from rotating. Attached Figure Description

[0017] 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 skilled in the art are within the protection scope of the present utility model.

[0018] Embodiments of this utility model: such as Figure 1-5 The diagram illustrates a screen-rotatable mobile phone stand structure, comprising a stand fixing mechanism 1, a screen fixing mechanism 2, a support base 3, a universal ball 4, a threaded cover 5, and a connecting block 6. The support base 3 is fixedly connected to the stand fixing mechanism 1, and the connecting block 6 is fixedly connected to the screen fixing mechanism 2. The end face of the support base 3 has a groove 7 that matches the universal ball 4. The threaded cover 5 is threadedly connected to the end of the support base 3, limiting the universal ball 4 within the groove 7 and the threaded cover 5. The end face of the threaded cover 5 has a through hole 8, through which the connecting block 6 passes and is fixedly connected to the universal ball 4. The threaded cover 5 has a limiting ring 9 inside, and the universal ball 4 is rotatably disposed within the limiting ring 9. The inner diameters at both ends of the limiting ring 9 are smaller than the inner diameter of the middle section, preventing the universal ball 4 from detaching from the limiting ring 9. The limiting ring 9 is slidably disposed within the threaded cover 5 and slides along the axial direction of the threaded cover 5. A damping elastic component 10 is fixedly disposed at the end of the limiting ring 9, and the other end of the damping elastic component 10 is fixedly connected to the inner wall of the threaded cover 5.

[0019] The bracket fixing mechanism 1 and the screen fixing mechanism 2 are existing technologies and will not be described in detail here.

[0020] It is worth noting that the damping elastic component 10 includes a damping rubber block and a pressure spring. When the road surface is bumpy, the pressure spring always gives the limiting ring 9 a push towards the groove 7, so that the universal ball 4 always presses against the groove 7. The rubber block is used to buffer and absorb vibration, thereby preventing the universal ball 4 from rotating.

[0021] With the above structure, when in use, pulling the screen fixing mechanism 2 outward can make the universal ball 4 leave the groove 7, making it easy to rotate the screen and adjust the screen angle. After the adjustment is completed, the screen fixing mechanism 2 is released, and the damping elastic component 10 can push the limiting ring 9 to move to one side of the groove 7, thereby pressing the universal ball 4 against the groove 7 for fixing.

[0022] like Figure 4 , 5 As shown, a ball bearing 11 is embedded in the inner wall of the limiting ring 9. The ball bearing 11 rotates to be disposed inside the limiting ring 9, and the surface of the ball bearing 11 contacts the surface of the universal ball 4.

[0023] Through the above structure, the setting of ball 11 can reduce the friction between the limiting ring 9 and the universal ball 4, thereby making the universal ball 4 rotate more smoothly and facilitating the adjustment of the screen angle.

[0024] like Figure 3 , 5 As shown, the threaded cover 5 has a limiting sleeve 12 corresponding to the limiting ring 9 inside, and the limiting ring 9 is slidably disposed inside the limiting sleeve 12.

[0025] With the above structure, the setting of the limiting sleeve 12 can restrict the movement of the limiting ring 9 along the axial direction of the limiting sleeve 12, and prevent the limiting ring 9 from deflecting when adjusting the screen angle, so that the damping elastic component 10 cannot push the universal ball 4 back into the groove 7 smoothly.

[0026] like Figure 3 , 4 As shown, the limiting ring 9 is provided with a limiting rib 13 on the outside, and the limiting sleeve 12 is provided with a corresponding limiting groove 14 on the inner wall. The limiting rib 13 is slidably disposed in the limiting groove 14.

[0027] With the above structure, the setting of the limiting rib 13 and the limiting groove 14 can prevent the limiting ring 9 from rotating when the screen is rotated horizontally, thereby preventing damage to the damping elastic component 10, and also improving the screen angle fixing effect.

[0028] like Figure 3 As shown, the inner wall of the groove 7 is provided with a resistance pad layer 15 for increasing friction.

[0029] It is worth noting that the resistance pad 15 is made of rubber and silicone, which has high friction and a buffering and energy-absorbing effect, further reducing the impact of vehicle body vibration on the universal ball.

[0030] like Figure 1 , 3 As shown, a dustproof silicone sleeve 16 is provided between the outer side of the threaded cover 5 and the screen fixing mechanism 2, and the connecting block 6 is located inside the dustproof silicone sleeve 16.

[0031] With the above structure, the dustproof silicone sleeve 16 can prevent dust from entering and reducing the friction between the omnidirectional ball 4 and the resistance pad 15.

[0032] When in use, by pulling the screen fixing mechanism outward, the universal ball can be moved away from the groove, making it easy to rotate the screen and adjust the screen angle. After the adjustment is completed, the damping elastic component can push the limiting ring to move to one side of the groove, thereby pressing the universal ball against the groove for fixation.
