And when the clamping suite rotates from the transverse direction to the vertical direction, the driving of the rotary clamping mechanism to the left clamping arm and the right clamping arm is relieved. The utility model provides a clamp, which can realize the switching use of a horizontal screen and a vertical screen, automatically clamp through gravity in a vertical screen state, and further clamp directly through a rotary clamping mechanism when switching to a horizontal screen, and the clamping action is applied through the rotary clamping mechanism in the horizontal screen switching rotation process, and can be realized only through rotation. Extra locking or unlocking actions are not needed, and the operation is simple.

Description

Technical Field

[0001] The utility model relates to the technical field of brackets, in particular to a clamp. Background Art

[0002] A phone stand is a device used to support and secure a phone so that it can rest stably on a table, countertop, or other flat surface. Phone stands are typically made of sturdy materials (such as metal or plastic) and have an adjustable design to accommodate different phone sizes and angles.

[0003] The car gravity holder is a type of mobile phone holder. The current car gravity holder cannot provide a good experience of using the mobile phone horizontally. When the user wants to use the mobile phone horizontally, either the holder loses the clamping function directly, or the clamping is very unstable, or cumbersome additional operations are required to complete the horizontal switch. Especially for the models that require additional operations, if the user forgets to operate and directly rotates the screen horizontally or vertically, it may also damage the car interior.

[0034] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0035] A clamp comprises a clamping kit 2 for clamping an object, and a connecting head 1 for supporting the clamping kit 2, wherein the connecting head 1 is used to be connected to a carrier, and the connecting head 1 is rotatably connected to the clamping kit 2 so that the clamping kit 2 can be rotated relative to the connecting head 1 to a vertical position or a horizontal position;

[0036] The clamping kit 2 includes a shell 21, a clamping mechanism 22 for clamping an object, and a rotating clamping mechanism 23 for maintaining the clamping state of the clamping kit 2 when it is horizontal. The clamping mechanism 22 and the rotating clamping mechanism 23 are arranged on the shell 21; in this embodiment, the shell 21 includes a rear shell 211, a front shell 4, and a fixing plate 5.

[0037] The clamping mechanism 22 comprises a left clamping arm 221, a right clamping arm 222, a bottom support arm 223, a connecting rod mechanism 26, and a reset member 27. The left clamping arm 221 and the right clamping arm 222 are linked to the bottom support arm 223 through the connecting rod mechanism 26, and the reset member 27 provides a force for the bottom support arm 223 to move upward. When the electronic device is placed in the clamping kit 2, the clamping mechanism 22 clamps the electronic device through the connecting rod mechanism 26 due to the action of gravity.

[0038] The rotating clamping mechanism 23 can selectively drive the clamping mechanism 22; when the clamping kit 2 rotates from vertical to horizontal, the rotating clamping mechanism 23 provides the left clamping arm 221 and the right clamping arm 222 with a force that tends to move toward each other; when the clamping kit 2 rotates from horizontal to vertical, the driving of the rotating clamping mechanism 23 on the left clamping arm 221 and the right clamping arm 222 is released;

[0039] The clamp also includes a limiting mechanism, which is used to provide resistance to prevent the clamping kit 2 from leaving the vertical position or the horizontal position, so that the clamping kit 2 is positioned in the vertical position or the horizontal position. The clamping kit 2 can switch to the vertical position or the horizontal position by only overcoming the torque in the rotation direction.

[0040] The utility model provides a clamp that can realize the switching between horizontal and vertical screens, and the clamping is more stable in both horizontal and vertical screen states. When switching to the horizontal screen state, it can be further clamped by rotating the clamping mechanism, and the clamping action is applied by rotating the clamping mechanism during the horizontal screen switching rotation process, without the need for additional locking and unlocking actions, and the operation is simple. When switching between horizontal and vertical screens, the limit can be released by only overcoming the torque in the rotation direction of the clamping kit, and there is no problem of forgetting the unlocking action and directly switching between horizontal and vertical screens to damage the fan blades of the car air outlet.

[0041] Further, as a preferred embodiment of the present solution but not limiting, the link mechanism 26 includes a first link 261 and a second link 262, one end of the first link 261 is movably connected to the bottom support arm 223, and the other end of the first link 261 is movably connected to the left clamp arm 221; one end of the second link 262 is movably connected to the bottom support arm 223, and the other end of the second link 262 is movably connected to the right clamp arm 222. When the bottom support arm 223 moves, it drives the first link 261 and the second link 262, thereby driving the left clamp arm 221 and the right clamp arm 222 to move closer to each other for clamping or move away from each other for loosening. Although the first connecting rod 261, the second connecting rod 262 and the bottom support arm 223, the left clamp arm 221, and the right clamp arm 222 in the connecting rod mechanism in the accompanying drawings are specifically connected by hinges, they are not limited to this specific movable connection method, as long as the bottom support arm 223 can respectively drive the left clamp arm and the right clamp arm to move through the first connecting rod and the second connecting rod when moving.

[0042] Further, as a preferred implementation manner of the present solution but not a limitation, the first connecting rod 261 is hingedly connected to the bottom supporting arm 223 , and the second connecting rod 262 is hingedly connected to the bottom supporting arm 223 .

[0044] Further, as a preferred embodiment of the present invention but not a limitation, the first connecting rod 261 is hingedly connected to the bottom support arm 223, and the first connecting rod 261 is hingedly connected to the left clamping arm 221; the second connecting rod 262 is hingedly connected to the bottom support arm 223, and the second connecting rod 262 is hingedly connected to the right clamping arm 222.

The connector 1 remains stationary, and when the clamping kit 2 rotates from vertical to horizontal, the first meshing portion 2321 meshes with the second meshing portion 2231; when the clamping kit 2 rotates from horizontal to vertical, the meshing is released.

The meshing process of the first meshing portion 2321 and the second meshing portion 2231 is as follows: after the initial meshing, the follower 232 still moves a small distance in the positive direction under the action of the active member 231, thereby driving the bottom support arm 223 to move a small distance downward. Since the clamping mechanism 22 is a linkage mechanism, the left clamping arm 221 and the right clamping arm 222 are further clamped.

[0049] Further, as a preferred embodiment of the present solution but not a limitation, the bottom support arm 223 is provided with a first hinge shaft 2233 and a second hinge shaft 2232, and the bottom support arm 223 is hinged to the first connecting rod 261 through the first hinge shaft 2233, and is hinged to the second connecting rod 262 through the second hinge shaft 2232. It should be understood that the first connecting rod 261 and the second connecting rod 262 can also be hinged to the bottom support arm 223 by using a common hinge shaft; compared with the structure of one hinge shaft, the structure using two hinge shafts in the attached drawings can reduce the thickness of the hinge point, making the product thinner.

[0053] Furthermore, as a preferred embodiment of the present invention but not a limitation, the rotating clamping mechanism 23 also includes a switching groove 236 provided on the active member 231, and a switching block 235 provided on the driven member 232. When the clamping kit 2 is rotated to a vertical position or a horizontal position relative to the connecting head 1, the switching groove cooperates with the switching block to drive the driven member to move.

The torsion spring is sleeved on the first hinge shaft 2233 and the second hinge shaft 2232.

[0057] Further, as a preferred embodiment of the present solution but not a limitation, the noise reduction member includes a first magnetic portion 281 provided on the fixing plate 5, and a second magnetic portion 282 provided on the bottom support arm 223. When the electronic device is removed from the clamp, the clamp is in an open state, and the second magnetic portion 282 on the bottom support arm 223 and the first magnetic portion 281 are attracted by magnetic force, thereby reducing the noise of the clamp.

[0058] Further, as a preferred embodiment of the present invention but not limiting, the ends of the first hinge shaft and the second hinge shaft are provided with openings 2235 and inclined end surfaces 2236. The two cooperate to allow the bottom support arm and the first connecting rod and the second connecting rod to be quickly inserted and installed.

[0059] Furthermore, as a preferred implementation mode of the present invention but not a limitation, the limiting mechanism includes a first limiting platform 33 and a second limiting platform 34 arranged on the switching groove 236, and a pushing member that presses the driven member against the active member, and the pushing member is preferably a spring.

[0061] Further, as a preferred embodiment of the present invention but not a limitation, the clamping kit 2 can switch between the horizontal and vertical directions by only overcoming the torque in the rotation direction. "Only overcoming the torque in the rotation direction of the clamping kit 2" means that there is no additional unlocking action before or during rotation.

[0062] Further, as a preferred implementation of the present solution but not limiting, a guide groove 51 is provided on the fixing plate 5. The guide groove guides the sliding direction of the left clamp arm and the right clamp arm when they are extended and retracted.
