[0045] The utility model provides a height adjusting mechanism. It aims at improving the problems of the existing electrical lifting structure which needs to consume power to drive, resulting in the increase of power consumption and the complex assembly method.

[0046] Please refer to Figures 1-2 In an embodiment of the present application, the height adjusting mechanism 100 includes a support structure 1, a lifting structure 2, a connecting piece 3 and a switching structure 4. The support structure 1 is used to support the installation platform. The lifting structure 2 includes a lifting part 21 and a driving part 22. The driving part 22 is arranged on the support structure 1 and is drivingly connected with the lifting part 21 to drive the lifting part 21 to move up and down. During the movement of the lifting part 21, the lifting part 21 has a moving state of continuously moving up and down and a stopping state of stopping. The connecting piece 3 is used to fixedly connect the rear shell 220 of the screen 200 and is fixedly connected with the lifting part 21 to synchronously move with the lifting part 21 and drive the screen 200 to move up and down. The switching structure 4 is arranged on the lifting part 21. The switching structure 4 is used to switch the lifting part 21 between the moving state and the stopping state under the action of external force.

[0047] The utility model discloses a technical scheme, the lifting portion 21 is always in the stop state, when the height adjusting mechanism 100 needs to drive the screen 200 to go up and down and adjust, the external force is added to the switching structure 4, to make the switching structure 4 drive the lifting portion 21 from the stop state and switch to the active state, at this time, the lifting portion 21 is along up and down and active, and drives the screen 200 along up and down and synchronous activity through the connecting piece 3, when the lifting portion 21 drives the screen 200 and goes up and down and active to the target height through the connecting piece 3, the external force is added to the switching structure 4 again, at this time, the switching structure 4 can drive the lifting portion 21 from the active state and switch back to the stop state, at this time, the lifting portion 21 stops active, and the lifting portion 21 can force the screen 200 to stop at the height through the connecting piece 3, to complete the lifting adjustment of the screen 200. Such setting makes the screen 200 go up and down and adjust in up and down direction not need additional motor control, and the state of the lifting portion 21 is switched through the external force and drive the switching structure 4, that is, can realize the lifting of the screen 200, to make the height of the screen 200 can be adjusted according to different use scene, and assembly is simple, can satisfy the demand of user in different scene.

[0048] It can be understood that the utility model does not limit the specific form of the installation platform, for example, the installation platform can be ground, desktop, cabinet or other structure, and the specific form is determined according to the use scene of the user.

[0049] It needs to be explained that when the lifting part 21 is in the active state, the utility model also does not limit the specific direction of the lifting part 21 moving up and down, for example, in an embodiment of the utility model, when the lifting part 21 is in the active state, the lifting part 21 continuously moves upwards, in this embodiment, when the height of the screen 200 needs to be raised, an external force is applied to the switching structure 4, the switching structure 4 can drive the lifting part 21 to switch from the stop state to the active state under the drive of the external force, at this time, the lifting part 21 moves upwards and drives the screen 200 to move upwards synchronously to raise the height of the screen 200, adapt to the requirement of the user, when the required height is reached, the switching structure 4 drives the lifting part 21 to switch back from the active state to the stop state under the drive of the external force, thereby fixing the screen 200 to this height; if the user needs to adjust the height of the screen 200 downwards, an external force is applied to the switching structure 4, the switching structure 4 can drive the lifting part 21 to switch from the stop state to the active state under the action of the external force, the lifting part 21 in the active state has the tendency of moving upwards, at this time, the user can limit the tendency of the lifting part 21 moving upwards by manual force and apply downward pressure to the lifting part 21, thereby driving the lifting part 21 to move downwards and driving the screen 200 to move downwards to lower the height of the screen 200, adapt to the requirement of the user, when the screen 200 is lowered to the required height, the switching structure 4 drives the lifting part 21 to switch back from the active state to the stop state under the drive of the external force, thereby fixing the screen 200 to this height.

[0050] In another embodiment of the utility model, when the lifting part 21 is in the active state, the lifting part 21 continuously moves downwards, and in this embodiment, when it is needed to lower the height of the screen 200, the switching structure 4 drives the lifting part 21 to switch from the active state to the stop state, the lifting part 21 moves downwards and drives the screen 200 to move downwards, thereby lowering the height of the screen 200 to meet the use demand of the user, and when the height of the screen 200 reaches the demand height of the user, the switching structure 4 switches the lifting part 21 from the active state back to the stop state, so as to fix the screen 200 at this height; when the user needs to adjust the height of the screen 200 upwards, the switching structure 4 drives the lifting part 21 to switch from the stop state to the active state, at this time, the lifting part 21 has a downward movement trend, the user can manually limit the downward movement of the lifting part 21 and provide an upward supporting force to the lifting part 21 or the screen 200, thereby driving the lifting part 21 to move upwards and driving the screen 200 to move upwards to raise the height of the screen 200 to meet the use demand of the user, and when the height of the screen 200 is raised to the demand height of the user, the switching structure 4 drives the lifting part 21 to switch from the active state back to the stop state to fix the screen 200 at the demand height of the user.

[0051] Therefore, when the lifting part 21 is in the active state, the specific upward movement direction of the lifting part 21 can be selected according to the actual setting, and the utility model does not limit this.

[0052] Specifically, in the utility model, when the lifting part 21 is in the active state, the lifting part 21 can continuously move upwards.

[0053] It also needs to be explained that, since the driving part 22 in the utility model does not set an additional motor to drive the lifting part 21 to move, when the user forces the lifting part 21 to move reversely, it will not cause any damage to the driving part 22, so as to ensure the service life of the height adjusting mechanism 100.

[0054] In order to facilitate the user to apply an external force to the switching structure 4 to switch the state of the lifting part 21, in an embodiment of the utility model, the switching structure 4 comprises a handle, and the handle is used for the user to operate to drive the lifting part 21 to switch between the active state and the stop state during the operation of the user. In this way, the user can use the hand to operate the handle, thereby switching the state of the lifting part 21, and the operation is simple, convenient and easy to use.

[0055] Of course, in other embodiments of the present application, the switching structure 4 can also be provided as a knob or other structure, and in actual installation, it can be selected according to requirements, and the present application does not limit this.

[0056] Further, it should be noted that, please refer to Figures 7-8 Irrespective of whether the lifting part 21 is continuously moving upward or continuously moving downward when the lifting part 21 is in the active state, the lifting part 21 has a maximum moving stroke in the direction, and when the lifting part 21 moves to the maximum moving stroke, the lifting part 21 still stops moving even if the lifting part 21 is still in the active state.

[0057] When the lifting part 21 is continuously moving upward when the lifting part 21 is in the active state, the maximum moving stroke of the lifting part 21 is the highest ground clearance of the screen 200; and when the lifting part 21 is continuously moving downward when the lifting part 21 is in the active state, the maximum moving stroke of the lifting part 21 is the lowest ground clearance of the screen 200.

[0058] Of course, the present application does not limit the specific values of the highest ground clearance and the lowest ground clearance of the screen 200, and in the present application, the highest ground clearance and the lowest ground clearance of the screen 200 can be selected according to actual installation.

[0059] In a specific embodiment of the present application, the highest ground clearance of the screen 200 is A, A = 750 mm; and the lowest ground clearance of the screen 200 is B, B = 550 mm.

[0060] In addition, the present application does not limit the specific structure of the driving part 22, and in an embodiment of the present application, the driving part 22 can be provided as a fixed pulley structure and a counterweight, the counterweight is drivenly connected with the lifting part 21 through a rope, and the weight of the counterweight and the sum of the weights of the lifting part 21 and the screen 200 are different, for example, when the weight of the counterweight is greater than the sum of the weights of the lifting part 21 and the screen 200, the switching structure 4 switches the lifting part 21 from the stop state to the active state, at this time, the restriction on the counterweight is released, the counterweight moves downward, at this time, under the action of force transmission of the rope and the action of changing direction of force of the fixed pulley structure, the weight of the counterweight is equivalent to the upward pulling force of the rope to the lifting part 21, so as to drive the lifting part 21 and the screen 200 to continuously move upward until the lifting part 21 moves to the maximum moving stroke; when the weight of the counterweight is less than the sum of the weights of the lifting part 21 and the screen 200, the continuous moving direction of the lifting part 21 when the lifting part 21 is in the active state is opposite.

[0061] In another embodiment of the utility model, the driving part 22 can also be provided as a pressure driving part, at this time, if the lifting part 21 is in the stop state, the pressure in the pressure driving part is stable to provide stable support for the lifting part 21, if the lifting part 21 is in the active state, at this time, the pressure driving part has a pressure difference, under the action of the pressure difference, the lifting part 21 is driven to move up and down, thereby realizing the continuous movement of the lifting part 21 up and down.

[0062] It should be noted that the utility model does not limit the pressure medium in the pressure driving part, in an embodiment of the utility model, the pressure medium in the pressure driving part is gas, in another embodiment of the utility model, the pressure medium in the pressure driving part is liquid.

[0063] Specifically, in the utility model, the driving part 22 is provided as the pressure driving part, and the pressure medium in the pressure driving part is gas.

[0064] In a specific embodiment of the utility model, the lifting part 21 and the pressure driving part form a gas spring hydraulic rod structure, the pressure driving part is provided with a pressure cavity, and an upper end is provided with a through hole communicating with the pressure cavity, the lifting part 21 includes a lifting rod, the lifting rod at least partially extends into the pressure cavity from the through hole, and the lower end of the lifting rod is provided with a piston, the piston slides against the side wall of the pressure cavity, and is in sliding seal with the side wall of the pressure cavity, so as to separate the pressure cavity into a first chamber and a second chamber distributed from top to bottom, the air pressure of the first chamber is always greater than that of the second chamber, the pressure driving part is also provided with a pressure pipeline communicating the first chamber and the second chamber, the communication and blockage of the pressure pipeline are switched by the switching structure 4, when the lifting rod is in the stop state, the pressure pipeline is blocked, when the lifting rod is in the active state, the pressure pipeline is communicated.

[0065] In this embodiment, when the lifting rod is in the stop state, the pressure pipeline is blocked, the first chamber is isolated and sealed from the second chamber, the gas in the second chamber cannot escape from the second chamber, under the action of air pressure, the gas in the second chamber supports the piston, and then supports the lifting rod and the screen 200, so that the lifting rod and the screen 200 can be stably at the current height; when it is necessary to adjust the height of the screen 200, the switching device is unblocked under the action of external force to communicate the pressure pipeline, so that the lifting rod is switched from the stop state to the active state, at this time, the first chamber communicates with the second chamber, because the pressure in the first chamber is greater than that in the second chamber, the gas in the first chamber will be driven by the pressure difference to move to the second chamber through the pressure pipeline, at this time, the pressure difference between the first chamber and the second chamber is reduced, and the gas in the second chamber is increased, the gas in the second chamber will drive the piston to move upward, and then drive the lifting rod and the screen 200 to move upward, and because the pressure in the first chamber is always greater than that in the second chamber, there is always a pressure difference between the first chamber and the second chamber, therefore, when the lifting rod is in the active state, the gas content in the second chamber will continue to increase, thereby continuously driving the piston to move upward, so that the lifting rod continuously moves upward in the active state until the lifting rod moves to the maximum active stroke; and when the lifting rod is in the active state, if it is necessary to drive the screen 200 to move downward, the user can limit the upward movement of the lifting rod by applying a downward pressure to the lifting rod or the screen 200, so that the sum of the weight of the lifting rod and the screen 200 and the downward pressure applied by the user is greater than the pressure difference between the first chamber and the second chamber, at this time, the piston moves downward to press the gas in the second chamber, and the gas in the second chamber flows reversely from the second chamber to the first chamber, so as to realize the height reduction of the screen 200.

[0066] It should be noted that, in the utility model, the lifting structure 2 and the connecting piece 3 are both force transmission pieces of the support structure 1 supporting the screen 200, and the lifting structure 2 is an adjusting piece adjusting the height of the screen 200 in the upward and downward directions, when the lifting structure 2 is used as a force transmission piece to support the screen 200, in order to avoid that the screen 200 is angularly deviated in the first horizontal direction or the second horizontal direction, so that the lifting structure 2 is dislocated or deformed, and the lifting and adjusting work of the lifting structure 2 is affected, and in order to improve the supporting capacity of the height adjusting mechanism 100 to the screen 200, please refer to Figures 3-5In an embodiment of the utility model, the connecting piece 3 has two installation ends opposite in the first horizontal direction, one of the installation ends is used for connecting the rear shell 220, the other installation end is concave with a sliding groove 31, the sliding groove 31 is arranged along the up and down direction, the sliding groove 31 is provided with an adapter 5 sliding along the up and down direction, and the adapter 5 is fixedly connected with the support structure 1. By setting the adapter 5 and the sliding groove 31 as the new force transmission element between the support structure 1 and the rear shell 220, the force transmission path between the support structure 1 and the rear shell 220 can be increased, when the screen 200 is angularly offset in the first horizontal direction or the second horizontal direction, the sliding groove 31 and the adapter 5 can directly transmit the offset force to the support structure 1, and the screen 200 is stabilized by the support structure 1, so that the support stability of the support structure 1 to the screen 200 is improved, and since the adapter 5 is slidingly arranged in the sliding groove 31 along the up and down direction, when the lifting part 21 moves along the up and down direction, the adapter 5 can move relative to the sliding groove 31, so that the ability of the lifting part 21 to adjust the height of the screen 200 is not affected.

[0067] Of course, other structures can also be set to improve the support ability of the height adjusting mechanism 100 to the screen 200, in an embodiment of the utility model, a ball nut is rotatably arranged on the other installation end of the connecting piece 3 along the up and down direction, the ball nut is sleeved on a lead screw extending along the up and down direction, and the lower end of the lead screw is fixedly connected with the support structure 1. By setting the ball nut and the lead screw, the offset of the screen 200 can be limited, the influence of the offset of the screen 200 on the lifting structure 2 is reduced, and when the lifting part 21 moves along the up and down direction, the ball nut can move synchronously with the connecting piece 3, so that the ability of the lifting part 21 to adjust the height of the screen 200 is not affected.

[0068] In other embodiments of the utility model, other structures can also be set to enhance the support ability of the height adjusting mechanism 100 to the screen 200 without affecting the lifting adjustment ability of the lifting part 21.

[0069] Specifically, in the utility model, the support ability of the height adjusting mechanism 100 is enhanced by setting the sliding groove 31 and the adapter 5.

[0071] In other embodiments of the utility model, the chute 31 can also be provided with other numbers, specifically, in actual setting, it can be selected according to requirements.

[0072] Similarly, the utility model is not limited to the specific number of the adapter 5 arranged in each chute 31, for example, in an embodiment of the utility model, only one adapter 5 is arranged in each chute 31, in another embodiment of the utility model, two adapters 5 are arranged in each chute 31, two adapters 5 are spaced apart along the up-down direction, and are all transmissionally connected to the support structure 1, in still another embodiment of the utility model, three adapters 5 are arranged in each chute 31, three adapters 5 are spaced apart along the up-down direction, and are all transmissionally connected to the support structure 1.
