[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. Now, in conjunction with the accompanying drawings, a detailed description of the preferred embodiments of the present utility model will be given.

[0030] The present invention provides a support seat. Figures 1 to 4As shown, the bracket base includes a clamping plate 1, a pressure plate 2, a screw 3, an inner sleeve assembly 4, an outer sleeve assembly 5, a clamping knob 6, a locking knob 7, and a first support arm 8. The clamping plate 1 has at least one clamping claw 11, which forms a clamping space 12. The pressure plate 2 is located in the clamping space 12. One end of the screw 3 is connected to the pressure plate 2, and the other end passes through the clamping plate 1 from one side of the clamping space 12. On the side of the clamping plate 1 facing away from the clamping space 12, the inner sleeve assembly 4 is rotatably mounted on the screw 3 and threadedly connected to the screw 3. The clamping knob 6 is mounted on the inner sleeve assembly 4. The outer sleeve assembly 5 is mounted on the inner sleeve assembly 4 and connected to the clamping plate 1. The locking knob 7 is mounted on the outer sleeve assembly 5 and threadedly connected to the outer sleeve assembly 5. The first support arm 8 is mounted on the outer sleeve and is located on the side of the locking knob 7 closest to the clamping plate 1.

[0031] When the clamping knob 6 of the bracket seat of the present invention is rotated, the clamping knob 6 drives the inner sleeve assembly 4 to rotate. The inner sleeve assembly 4 is extended and retracted relative to the clamping plate 1 by threadedly driving the screw 3, thereby driving the clamping plate 2 to move. The clamping plate 2 cooperates with the clamping claw 11 to achieve clamping at a clamping position, such as a corner of a car's center console display screen. The bracket seat is also provided with a locking knob 7 and an outer sleeve 5, wherein the locking knob 7 is sleeved on the outer sleeve 5 and is threadedly connected to the outer sleeve 5. Rotating the locking knob 7 can lock or release the first arm 8, thereby achieving angle adjustment and secure positioning of the first arm 8. Even when bumped or shaken, the arm is not easily rotated unexpectedly and can be maintained at the operating angle, achieving a good positioning effect of the first arm 8.

[0032] Specifically, the clamping claws 11 can be provided on two adjacent sides of the clamping plate 1, in which case the bracket can be clamped on a corner of the car's center console display screen. Alternatively, the clamping claws 11 can be provided on one side of the clamping plate 1, in which case the bracket can be clamped on the edge of the car's center console display screen. Of course, the bracket of the present invention can also be applied to other applicable clamping positions. The scenario of application on the car's center console display screen exemplified here is only one example.

[0033] The first arm 8 can be connected to a clamping mechanism via the second arm 20 described below, which clamps electronic devices such as mobile phones. The outer sleeve 5 can be mounted on the clamping plate 1 using screws. The outer sleeve 5 is provided with external threads, and the locking knob 7 is provided with internal threads, thereby achieving a threaded connection between the outer sleeve 5 and the locking knob 7. When the locking knob 7 is rotated, it moves toward the clamping plate 1, pressing the first arm 8, thereby locking the first arm 8. When the locking knob 7 moves away from the clamping plate 1, it releases the first arm 8, thereby adjusting the operating angle of the first arm 8. The pressing plate and the screw 3 can be fixed together using screws.

[0034] Specifically, further combining Figures 5 to 7As shown, the inner sleeve assembly 4 includes an inner sleeve 41 and a nut 42. The inner sleeve 41 is rotatably mounted on the screw 3, and the nut 42 is fixedly mounted in the inner sleeve 41 so that the inner sleeve 41 can drive the nut 42 to rotate synchronously. The nut 42 is threadedly connected to the screw 3. The outer sleeve 5 is mounted on the inner sleeve 41, and the clamping knob 6 is mounted on the end of the inner sleeve 41 away from the clamping plate 1. When the clamping knob 6 is rotated, the inner sleeve 41 rotates, which in turn drives the nut 42. The nut 42 drives the screw 3 to extend and retract on the clamping plate 1, thereby driving the clamping plate 2 to extend and retract in the clamping space 12, thereby tightening or loosening the bracket seat. A limiting edge 413 is provided on the peripheral wall of the inner sleeve 41 near the clamping plate 1. A limiting groove 52 is provided in the outer sleeve 5 corresponding to the limiting edge 413. The limiting edge 413 is embedded in the limiting groove 52, thereby limiting the position of the inner sleeve 41 and allowing the inner sleeve 41 to rotate within the outer sleeve 5. The nut 42 cooperates with the screw rod 3, so the structure is stable, has a long service life, and is not easily damaged.

[0035] Specifically, the outer wall of the end of the screw rod 3 connected to the pressure plate 2 is not provided with an external thread. An insertion cavity 411 is axially defined in the inner sleeve 41. An elastic member 9 is disposed in the insertion cavity 411 at the end away from the clamping plate 1. The elastic member 9 abuts against the end of the screw rod 3 away from the clamping plate 1. The elastic member 9 pushes the screw rod 3 through its elastic force, allowing the threaded start end of the screw rod 3 to easily engage with the nut 42.

[0036] The end of the inner sleeve 41 near the clamping plate 1 defines a mounting cavity 412 that communicates with the insertion cavity 411. The nut 42 is positioned within the mounting cavity 412. The side of the nut 42 has multiple edges, and the shape of the mounting cavity 412 is adapted to the shape of the nut 42. This allows the nut 42 to rotate after being installed within the mounting cavity 412. The provision of the mounting cavity 412 at the end of the inner sleeve 41 near the clamping plate 1 facilitates assembly of the nut 42.

[0037] An extension 51 is provided around the outer sleeve 5 at one end near the clamping plate 1. The extension 51 is secured to the clamping plate 1 via screws. The bracket seat includes a positioning piece 10, which is mounted on the outer sleeve 5 and positioned between the first arm 8 and the extension 51. The positioning piece 10 is positionally connected to the first arm 8, allowing the positioning piece 10 to rotate around the outer sleeve 5 along with the first arm 8. At least one spherical protrusion 101 is provided on the side of the positioning piece 10 facing the extension 51. The extension 51 is also provided with a plurality of positioning grooves 511 extending around the outer sleeve 5. Each of the positioning grooves 511 is located along the rotational trajectory of the spherical protrusion 101. When the first arm 8 rotates, it drives the positioning piece 10 to rotate. During this rotation, the spherical protrusion 101 engages with or disengages from the positioning groove 511. The cooperation between the spherical protrusion 101 and the positioning groove 511 serves to position the first arm 8 while enhancing the feel of the rotation operation. When the pressing knob 6 is pressed, the first arm 8 is pressed against the positioning piece 10 .

[0038] Specifically, the multiple positioning grooves 511 are evenly spaced, and the number of spherical protrusions 101 is equal to the number of positioning grooves 511 and is arranged one-to-one with the positioning grooves 511. This ensures that all spherical protrusions 101 are embedded in the corresponding positioning grooves 511, thereby improving the positioning effect of the first arm 8.

[0039] Furthermore, the positioning piece 10 is provided with a locking ridge 102, and the first arm 8 is provided with a first opening 81. The locking ridge 102 is locked in the first opening 81. By locking the locking ridge 102 with the first opening 81, the first arm 8 can drive the positioning piece 10 to rotate together. The first opening 81 extends along the length of the first arm 8. Thus, when the locking knob 7 releases the first arm 8, the first arm 8 can be adjusted within the length of the first opening 81, thereby achieving adjustment of the clamping position.

[0040] More specifically, the bracket base also includes a second arm 20, one end of which is rotatably connected to the end of the first arm 8 away from the clamping plate 1. The addition of the second arm 20 can extend the usable length of the clamping base, and the rotatable connection between the second arm 20 and the first arm 8 allows for adjustment of the clamping angle. The second arm 20 and the first arm 8 can be rotatably connected via a damping shaft. The other end of the second arm 20 is provided with an external component 30 for connecting to a clamping mechanism. The clamping mechanism for clamping the mobile phone can be mounted on the external component 30. The external component 30 can be, for example, a universal ball joint. When the angle between the first arm 8 and the second arm 20 is 180°, the external component 30 is on the same side as the clamping plate 1, and the end of the second arm 20 where the external component 30 is located is tilted toward the side opposite to the side where the external component 30 is located, facilitating the clamping mechanism to maintain a suitable clamping angle.

[0041] The present invention further discloses a bracket comprising a clamping mechanism and the bracket base described above, wherein the clamping mechanism is connected to the first arm 8. Specifically, the first arm 8 is connected to the clamping mechanism via the second arm 20 described above. The second arm 20 is provided with an external connection member 30, and the clamping mechanism is mounted on the external connection member 30.

[0042] It should be understood that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Those skilled in the art may modify the technical solutions described in the above embodiments, or make equivalent replacements for some of the technical features therein; and all these modifications and replacements should fall within the scope of protection of the claims attached to the present invention.
