[0036] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0037] It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a central component at the same time. When a component is considered to be "located on" another component, it may be directly located on the other component or there may be a central component at the same time. The terms "top", "bottom", "upper", "lower", "left", "right", "front", "back", and similar expressions used herein are for illustrative purposes only.

[0038] The embodiment of the present application provides a car mobile phone holder base, comprising a base body, an upper cover threadedly connected to the base body, and a pull-out arm clamped between the base body and the upper cover, and the base further comprises:

[0039] A first through hole is formed partially through the seat body along a first direction;

[0040] A first spring, located in the first through hole, with one end thereof abutting against an end of the seat body away from the upper cover;

[0041] A first limiting ball is located on a side of the first spring close to the upper cover, and when viewed along a second direction perpendicular to the first direction, a portion of the first limiting ball protrudes out of the first through hole along a direction close to the upper cover; the pull-out arm comprises:

[0042] A first limiting groove, wherein a plurality of the first limiting grooves are arranged in an array along the pulling direction, and are recessed along the first direction on a side of the pulling arm away from the upper cover, and cooperate with a portion of the first limiting ball protruding out of the first through hole.

[0043] The above-mentioned in-vehicle mobile phone holder base can maintain the stability of the holder during the process of adjusting the length with one hand through the structure of the spring and the limit ball. The spring abuts the limit ball and pushes it into the first limit groove. When the pull-out arm is pulled, the pull-out arm pushes the limit ball into the through hole until it moves to the position of the next limit groove. The spring pushes the limit ball to abut against another limit groove again, realizing the automatic locking function. It is no longer necessary to operate the screws with two hands to adjust the length of the holder, which greatly simplifies the user's operation process and improves the convenience of user experience and the ease of operation.

[0044] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0045] See also Figure 1-Figure 6 , the embodiment of the present application provides a car mobile phone holder base 100, including a base body 10, an upper cover 20 threadedly connected to the base body 10, and a pull-out arm 30 clamped between the base body 10 and the upper cover 20, the base also includes a first through hole 11, a first spring 12, a first limiting ball 13 and a first limiting groove 31;

[0046] A first through hole 11 is partially formed in the base body 10 along a first direction; a first spring 12 is located in the first through hole 11, and one end thereof abuts against an end of the base body 10 away from the upper cover 20; a first limiting ball 13 is located on a side of the first spring 12 close to the upper cover 20, and when observed along a second direction perpendicular to the first direction, a portion of the first limiting ball 13 protrudes out of the first through hole 11 along a direction close to the upper cover 20; the pulling arm 30 comprises: a first limiting groove 31; a plurality of the first limiting grooves 31 are arranged in an arranged manner along the pulling direction, and are recessed along the first direction on a side of the pulling arm 30 away from the upper cover 20, and cooperate with a portion of the first limiting ball 13 protruding out of the first through hole 11.

[0047] Specifically, the base 10, the upper cover 20 and the pull-out arm 30 constitute the main structure of the bracket. The base 10 provides a supporting base, the upper cover 20 is fixed on the base 10 and connected thereto, and the pull-out arm 30 serves to adjust the length of the bracket. When the length of the bracket needs to be adjusted, the user can pull the pull-out arm 30 to extend and retract it, thereby adjusting the length of the mobile phone bracket. The first through hole 11 allows the installation of the first spring 12 and the first limiting ball 13. The first spring 12 provides support and elasticity, while the first limiting ball 13 is used to resist the limiting groove to realize the positioning function and enhance the stability of the bracket. When the user pulls the pull-out arm 30, the first limiting ball 13 and the first limiting groove 31 cooperate.

[0048] Furthermore, the spring abuts the limit ball and pushes it into the limit groove. When the pull-out arm 30 is pulled, the pull-out arm 30 pushes the limit ball into the through hole until it moves to the position of the next limit groove. The spring pushes the limit ball to abut against another limit groove again, thereby realizing the automatic locking function. It is no longer necessary to use both hands to operate the tightness of the screws to adjust the length of the bracket, which greatly simplifies the user's operation process and improves the convenience of user experience and the ease of operation.

[0049] In a specific embodiment, the first through hole 11 extends inwardly to form a limiting ring 111, and the limiting ring 111 is located between the first spring 12 and the upper cover 20;

[0050] The portion of the first limiting ball 13 located in the first through hole 11 abuts against a side of the limiting ring 111 away from the upper cover 20 .

[0051] Specifically, the limiting ring 111 formed by the inward extension of the first through hole 11 provides a limited range for the movement of the limiting ball, preventing the limiting ball from moving too much in the first through hole 11, thereby ensuring the accuracy and stability of the bracket length adjustment. When the user pulls the drawer arm 30 to adjust the bracket length, the limiting ball moves in the first through hole 11, and is restricted by the limiting ring 111 and can only move within a limited range, thereby ensuring the accurate adjustment of the bracket length.

[0052] Furthermore, the first limiting ball 13 is located at a specific position of the first through hole 11 and abuts against the side of the limiting ring 111 away from the upper cover 20. The first limiting ball 13 is located at a specific position of the first through hole 11 and abuts against the side of the limiting ring 111 away from the upper cover 20, which is used to limit the movement range of the drawer arm 30, ensure that the length of the bracket is adjusted within a preset range, and stably lock after the adjustment is completed. When the user pulls the drawer arm 30, the first limiting ball 13 pushes into the limiting groove and is limited by the limiting ring 111 and the upper cover 20, ensuring the stable adjustment of the bracket length and firmly locking after reaching the preset length.

[0053] In a specific embodiment, when the pulling arm 30 is pulled, one of the first limiting grooves 31 cooperating with the first limiting ball 13 is switched to another first limiting groove 31, and the pulling arm 30 pushes the first limiting ball 13 into the first through hole 11 along a third direction opposite to the first direction;

[0054] When pulled to a position corresponding to another first limiting groove 31 , the first spring 12 pushes the first limiting ball 13 partially out of the first through hole 11 along the first direction to cooperate with another first limiting groove 31 .

[0055] Specifically, the design allows the pull-out arm 30 to switch between multiple positions when adjusting the length of the bracket, and the limit groove that cooperates with the first limit ball 13 allows the bracket length to be adjusted between multiple limit groove preset positions, increasing the adjustable range and flexibility of the bracket length. When the user pulls the pull-out arm 30, the limit groove on the pull-out arm 30 cooperates with the first limit ball 13, and when the pull-out arm 30 moves to the position of a limit groove, the limit ball will automatically enter the limit groove to lock the bracket length.

[0056] Furthermore, the function of the first spring 12 is to push the limiting ball out of the first through hole 11 when the drawer arm 30 moves to the position of another limiting groove, so as to cooperate with another limiting groove to ensure that the bracket can be stably locked when adjusted to different lengths. When the drawer arm 30 moves to the position of another limiting groove, the first spring 12 will be compressed, so that the limiting ball is pushed out of the first through hole 11, and then the limiting ball will cooperate with another limiting groove to lock the length of the bracket.

[0057] In a specific embodiment, a through first fixing hole 14 is opened at the center of the base body 10 along a first direction, and the first fixing hole 14 extends inward to form a step surface 141. A first screw hole 21 is opened at the center of the upper cover 20, and the screw head abuts against the step surface 141. The screw rod extends into the first screw hole 21 to connect and fix the base body 10 and the upper cover 20.

[0058] Specifically, the fixing hole provides a position and a channel for fixing the bracket assembly, so that the base 10 and the upper cover 20 can be connected through the channel. During the assembly process, the base 10 and the upper cover 20 are aligned so that the first fixing hole 14 corresponds to the first screw hole 21 of the upper cover 20 to facilitate the installation of the screw. The first fixing hole 14 extends inward to form a step surface 141, and the step surface 141 provides a support surface for supporting the screw head of the screw so that the screw can firmly connect the base 10 and the upper cover 20. The screw head of the screw is against the step surface 141, so that the screw can fix the position between the base 10 and the upper cover 20 to prevent them from loosening or separating.

[0059] Furthermore, the step surface 141 provides a support platform to ensure that the threaded portion of the screw does not completely enter the screw hole 21. This design maintains a fixed connection between the base 10 and the upper cover 20, while maintaining a certain gap, allowing the pull-out arm 30 to move freely when the bracket is fixed. When the threaded portion of the screw is screwed into the screw hole 21, due to the presence of the step surface 141, the threaded portion will not completely enter the screw hole 21, and a certain distance is retained. In this way, while keeping the bracket fixed, the pull-out arm 30 can still move freely within a certain gap between the base 10 and the upper cover 20.

[0060] In a specific embodiment, the second through hole 15 is formed partially through the base body 10 along the first direction;

[0061] The second spring 16 is located in the second through hole 15, and one end of the second spring 16 abuts against one end of the base body 10 close to the upper cover 20;

[0062] A second limiting ball 17 is located at a side of the second spring 16 away from the upper cover 20. When viewed along the second direction, a portion of the second limiting ball 17 protrudes out of the second through hole 15 in a direction away from the upper cover 20.

[0063] The seat body 10 also includes a rotating portion 18 and a cover portion covering the rotating portion 18. The rotating portion 18 is recessed in a first direction on one side close to the cover portion to form a second limiting groove 181, which is arranged around the rotating portion 18 and cooperates with the part of the second limiting ball 17 protruding out of the second through hole 15.

[0064] Specifically, a channel is provided for installing the second spring 16 and the second limiting ball 17 to ensure that they can be correctly installed in the seat body 10. The second spring 16 and the second limiting ball 17 are installed in the second through hole 15 so that they can correctly cooperate with other components and play their role. The second spring 16, located in the second through hole 15, provides a spring support for controlling the position of the second limiting ball 17, ensuring that the second limiting ball 17 can be moved and locked.

[0065] Furthermore, the second limiting ball 17 is located inside the seat body 10 and cooperates with the rotating part 18 to control the rotation position and locking state of the bracket. When the user rotates the bracket, the rotating part 18 cooperates with the second limiting ball 17, and the limiting ball is pushed by the spring force to switch from one limiting slot to another limiting slot, thereby controlling the rotation position and locking state of the bracket. The rotating part 18 is located inside the seat body 10 and cooperates with the cover body, providing a rotation mechanism for the bracket, so that the user can freely adjust the rotation angle of the bracket, and realize the locking function by cooperating with the second limiting ball 17. When the user rotates the bracket, the rotating part 18 cooperates with the cover body, and the rotation and locking of the bracket are realized through the action of the limiting slot and the second limiting ball 17. When the second limiting ball 17 switches from one limiting slot to another limiting slot, the rotation state of the bracket also changes accordingly.

[0066] In a specific embodiment, when the drawer arm 30 is rotated, the drawer arm 30 drives the upper cover 20 and the seat body 10 to rotate, and one of the second limiting grooves 181 matched with the second limiting ball 17 is switched to another second limiting groove 181, and the rotating part 18 pushes the second limiting ball 17 into the second through hole 15 along the third direction;

[0067] When the second limiting ball 17 is rotated to a position corresponding to another second limiting groove 181 , the second spring 16 pushes the second limiting ball 17 partially out of the second through hole 15 along the third direction to cooperate with another second limiting groove 181 .

[0068] Specifically, by rotating the drawer arm 30, the rotation function of the bracket is realized, so that the user can adjust the angle of the bracket to adapt to different viewing angles and usage requirements. When the user rotates the drawer arm 30, the drawer arm 30 is connected to the upper cover 20 and the base body 10, driving the upper cover 20 and the base body 10 to rotate together, thereby realizing the overall rotation of the bracket.

[0069] Furthermore, the second limiting ball 17 switches to another limiting groove and pushes into the second through hole 15 to control the locking position when the bracket rotates, ensuring that the bracket remains stable at a specific angle. As the bracket rotates, the second limiting ball 17 is pushed into the second through hole 15, and continues to switch from the current limiting groove to another limiting groove to achieve locking of the bracket in a new position. When the bracket rotates to the position of another limiting groove, the second spring 16 pushes the second limiting ball 17 out of the second through hole 15 to cooperate with the new limiting groove, thereby locking the bracket in the new position.

[0070] In a specific embodiment, the cover body 19 is provided with a through second fixing hole 192 along the first direction. When viewed along the first direction, the second fixing hole 192 is arranged on both sides of the center line of the cover body 19 to prevent the upper cover 20 from shaking when the pulling arm 30 is pulled.

[0071] Specifically, by opening the second fixing hole 192 in the cover body 19 along the first direction, the bracket is additionally fixed, preventing the upper cover 20 from shaking when the drawer arm 30 is pulled out, thereby improving the stability of the bracket. When the user pulls out the drawer arm 30, the second fixing hole 192 on the cover body 19 is connected to an additional fixing device (such as a screw, a pin, etc.) to additionally fix the upper cover 20 on the base 10 to prevent it from shaking.

[0072] Furthermore, by arranging the second fixing holes 192 on both sides of the center line of the cover body 19, it is ensured that the fixing device can evenly apply the fixing force, thereby enhancing the stability of the bracket. The fixing device connects the cover body 19 and the base 10 through the second fixing holes 192, and fixes the upper cover 20 on the base 10. Since the second fixing holes 192 are located on both sides of the center line of the cover body 19, the fixing force is evenly distributed, thereby preventing the bracket from being deflected or unstable during use.

[0073] Furthermore, there are multiple springs between the bases, which can generate various forces, including support, buffering, locking, etc. By fixing the upper cover 20, the overall structure of the bracket can be effectively stabilized, the influence of the springs can be reduced, and the stability and reliability of the bracket can be maintained.

[0074] In a specific embodiment, the base also includes a first pad 40 and a second pad 50. A accommodating groove 191 is provided on a side of the base body 10 close to the upper cover 20. The first pad 40 is arranged in the accommodating groove 191 and is located between the pull-out arm 30 and the base body 10. The second pad 50 is arranged between the pull-out arm 30 and the upper cover 20. The first pad 40 and the second pad 50 are both plastic layers.

[0075] Specifically, the main functions of the first pad 40 and the second pad 50 are to provide additional cushioning and support, while reducing friction and wear, and protecting the surface of the base and the bracket from damage. They can reduce the direct contact between the pull-out arm 30 and the seat body 10 and between the pull-out arm 30 and the upper cover 20, thereby reducing friction and wear and extending the service life of the bracket. Plastic is selected as the material of the first pad 40 and the second pad 50, which has good elasticity and wear resistance, can effectively absorb impact force, and is not easy to deform or break. In addition, the surface of the plastic layer is smooth, which can reduce friction with other components, making the operation of the bracket smoother.

[0076] Furthermore, the drawer arm 30, the upper cover 20 and the base 10 are all made of metal, and there is no cushion layer. The movement between them will cause wear and tear, and there are many problems such as unsmooth drawing. The existence of the plastic cushion layer is mainly to provide additional buffering and protection. They can reduce the direct contact between metal parts, thereby reducing friction and wear, and extending the service life of the bracket. In addition, the elasticity and softness of the plastic cushion layer can also reduce the impact and vibration between the parts.

[0077] Furthermore, during the use of the bracket, the metal parts provide the required stability and structural strength of the bracket, while the plastic cushion layer ensures smooth and safe operation. When the user needs to adjust the length or position of the bracket, the metal parts provide the necessary support and stability, while the plastic cushion layer reduces friction and resistance during operation, protecting the bracket and the equipment.

[0078] In a specific embodiment, the first gasket is provided with a first limiting hole 41 at a position corresponding to the first through hole 11, and the second gasket is provided with a second limiting hole 51. The upper cover 20 also includes a limiting column 211, and the limiting column 211 is arranged on a side of the upper cover 20 close to the base body 10. The central axis of the limiting column 211 coincides with the central axis of the second limiting hole 51 to prevent movement between the upper cover 20 and the second gasket 50.

[0079] Specifically, the design of the limiting column 211 and the second limiting hole 51 is to ensure that the relative position between the upper cover 20 and the second pad 50 remains stable. Through the cooperation of the limiting column 211 and the second limiting hole 51, the upper cover 20 can be prevented from accidentally moving or detaching during use, thereby improving the stability and safety of the bracket. The limiting column 211 is located on the side of the upper cover 20 close to the base 10, and corresponds to the second limiting hole 51 of the second pad 50. Ensure that the position between the upper cover 20 and the second pad 50 remains stable. Through cooperation with the second limiting hole 51, the limiting column 211 can effectively prevent the upper cover 20 and the second pad 50 from relative movement during pulling or rotating, thereby improving the stability and reliability of the bracket.
