Abstract

A support device includes a support structure, a carrier assembly, and an elastic assembly. The carrier assembly is configured to support a display device. The carrier assembly ascends and descends relative to the support structure. The elastic assembly is connected to the support structure and the carrier assembly and provides different support forces to the carrier assembly to support display devices of different weights.

First claim

What is claimed is:

1. A support device comprising:
a support structure;
a carrier assembly configured to support a display device, the carrier assembly ascending and descending relative to the support structure; and
an elastic assembly connected to the support structure and the carrier assembly and providing different support forces to the carrier assembly to support display devices of different weights;
wherein:
the elastic assembly includes:
a first elastic assembly including at least one second elastic member and at least one first elastic member, a fixed end of the at least one second elastic member being connected to the support structure; and
a second elastic assembly movably connected to the carrier assembly; and

a free end of the at least one second elastic member has a connection state and a disconnection state with the second elastic assembly:
in the connection state, the at least one second elastic member provides a support force to the carrier assembly; and
in the disconnection state, the second elastic member does not provide the support force to the carrier assembly.

2. The support device of claim 1 , wherein:
the first elastic assembly is arranged along an ascending and descending direction of the carrier assembly relative to the support structure; and
the second elastic assembly moves in a first direction along with ascending and descending of the carrier assembly, the first direction being perpendicular to the ascending and descending direction of the carrier assembly;
wherein a fixed end of the at least one first elastic member is connected to the support structure, a free end of the at least one first elastic member is connected to the carrier assembly, and the second elastic assembly has a connection state and a disconnection state with at least a part of a free end of the first elastic assembly:
in the connection state, the first elastic assembly and the second elastic assembly cooperate to provide a first support force to the carrier assembly; and
in the disconnection state, the first elastic assembly provides a second support force to the carrier assembly through the at least one first elastic member, the second support force being different from the first support force.

3. The support device according to claim 2 , wherein:
the support structure includes:
a base; and
a column arranged on the base in a vertical direction; and

the carrier assembly includes:
a carrier configured to fix the display device; and
an ascending and descending structure ascending and descending along the column, the carrier being connected to the ascending and descending structure to cause the display device to be able to move in the vertical direction.

4. The support device according to claim 3 , wherein:
a slide rail is arranged in the ascending and descending direction of the column;
the ascending and descending structure includes:
a first slide member moving along the slide rail in the ascending and descending direction and including:
a first chamber body arranged along the ascending and descending direction; and
a second chamber body arranged along the first direction, the first chamber body being communicated with the second chamber body in the ascending and descending direction;

the carrier includes:
a first connection piece configured to fix the display device; and
a second connection piece sleeved inside the first chamber body and moving towards the second chamber body, the first connection piece and the second connection piece having a predetermined angle; and

at least a part of the second elastic assembly is arranged in the second chamber body to cooperate with the second connection piece to move to ascend and descend in the second chamber body in the first direction.

5. The support device according to claim 4 , wherein the second elastic assembly includes:
a third elastic member; and
a first connector moving in the first direction relative to a first side wall of the second chamber body under an action of the third elastic member and the second connection piece to be connected to or disconnected from the first elastic assembly.

6. The support device according to claim 5 , wherein:
the fixed end of the at least one first elastic member is connected to the column, and the free end of the at least one first elastic member is fixedly connected to the first slide member; and
the fixed end of the at least one second elastic member is connected to the column, and the free end of the at least one second elastic member includes a plug position configured to plug the first connector in to connect the first elastic assembly and the second elastic assembly.

7. The support device according to claim 6 , wherein:
a second slide member moving in the ascending and descending direction is arranged in the column, and the free end of the second elastic member is fixedly connected to the second slide member; and/or
the support device further includes a fourth elastic member arranged on a bottom wall of the second chamber body and providing a resistance to the second connection piece when moving downward, a direction of an elastic force of the fourth elastic member being consistent with a movement direction of the second connection piece.

8. The support device according to claim 6 , wherein:
a concave member is arranged on a side of the second connection piece facing the first connector;
the second connection piece ascends and descends in the second chamber body to cause the first connector to abut against or not abut against the concave member;
in response to a first end of the first connector abutting against the concave member, a second end of the first connector is disconnected from the plug position; and
in response to the first end of the first connector not abutting against the concave member, the second end of the first connector is connected to the plug position.

9. The support device according to claim 8 , wherein:
in response to the first connection piece being connected to a display device of a first weight, the second connection piece is at a first position relative to the first slide member, the first end of the first connector abuts against the concave member, and the second end of the first connector is disconnected from the plug position;
in response to the first connection piece being connected to a display device with a second weight, the second connection piece moves relative to the first slide member, and the first end of the first connector slides out from inside of the concave member to move in the first direction to cause the second end of the first connector to be connected to the plug position; and
the first weight is less than the second weight.

10. An electronic apparatus comprising:
a display device; and
a supporting device including:
a support structure;
a carrier assembly configured to support the display device, the carrier assembly ascending and descending relative to the support structure; and
an elastic assembly connected to the support structure and the carrier assembly and providing different support forces to the carrier assembly to support display devices of different weights;
wherein:
the elastic assembly includes:
a first elastic assembly including at least one second elastic member and at least one first elastic member, a fixed end of the at least one second elastic member being connected to the support structure; and
a second elastic assembly movably connected to the carrier assembly; and

a free end of the at least one second elastic member has a connection state and a disconnection state with the second elastic assembly:
in the connection state, the at least one second elastic member provides a supp
