Abstract

The embodiment of the present application provides a balance mechanism and a mounting bracket. Wherein, the balance mechanism includes: a mounting part; a sliding part, which is slidably connected to the mounting part; a spring, the first end of the spring is fixed to the sliding part; an adjuster, which has a third end and a fourth end opposite to the third end, wherein the third end is connected to the mounting part, and the fourth end is connected to the second end of the spring. The adjuster is configured to adjust the spring, so as to stretch and compress the spring. The embodiments of the present application can reduce the cost of the balance mechanism and thereby reduce the cost of the mounting bracket.

First claim

What is claimed is:

1. A mounting bracket comprising a base, a connecting head, an upper arm, a lower arm, and a balance mechanism, the balance mechanism comprising:
a mounting part;
a sliding part slidably connected to the mounting part, wherein the sliding part slides on the mounting part such that a total length of the balance mechanism is changed;
a spring, a first end of which is fixed to the sliding part; and
an adjuster having a third end and a fourth end opposite to the third end, wherein the third end is connected to the mounting part and the fourth end is connected to a second end of the spring, and wherein the adjuster is configured to adjust the spring so as to stretch and compress the spring;
wherein the upper arm and the lower arm both are connected between the base and the connecting head such that a quadrilateral structure is formed between the base, the connecting head, the upper arm, and the lower arm, and
wherein a first end of the balance mechanism is connected to the base or to the upper arm, and a second end of the balance mechanism is connected to the lower arm or to the connecting head.

2. The mounting bracket according to claim 1 , wherein:
the first end of the spring of the balance mechanism is connected to the base or to the upper arm, and an end of the mounting part of the balance mechanism away from the sliding part is connected to the lower arm or to the connecting head; or
the first end of the spring of the balance mechanism is connected to the lower arm or to the connecting head, and the end of the mounting part of the balance mechanism away from the sliding part is connected to the base or to the upper arm.

3. The mounting bracket according to claim 1 , further comprising a panel, wherein the panel is rotationally connected relative to the connecting head, and wherein the rotation axis of the panel relative to the connecting head is generally in a vertical direction.

4. The mounting bracket according to claim 1 , wherein the mounting part comprises two first side plates opposite to each other and a first bottom plate fixed between the two first side plates, wherein each of the two first side plates has a first flanging arranged inward from an edge thereof, and wherein the sliding part is located between the first two side plates and the first flanging is used to limit the sliding part.

5. The mounting bracket according to claim 4 , wherein the sliding part comprises two second side plates opposite two each other and a first connector fixed between the two second side plates, and wherein the first end of the spring is fixed to the first connector and the second side plates are located between the two first side plates.

6. The mounting bracket according to claim 5 , wherein the sliding part further comprises a fixing member fixed between the two second side plates, an external thread is provided on an outer surface of the adjuster, and the adjuster is arranged to pass through the fixing member in a rotatable manner, and
wherein the second end of the spring is fixed with a second connector and the second connector is provided with an internal thread which matches with the external thread.

7. The mounting bracket according to claim 5 , wherein the first side plates and the second side plates each have a limiting structure provided thereon, and wherein the limiting structures are configured to limit the displacement of the first side plates relative to the second side plates.

8. The mounting bracket according to claim 4 , wherein each of the two first side plates has a first sliding groove provided thereon, wherein the balance mechanism further comprises a limiter fixed to the second end of the spring, and wherein both ends of the limiter are respectively located in the first sliding grooves of the two first side plates.

9. The mounting bracket according to claim 4 , wherein a second sliding groove is provided on the first bottom plate, a protrusion is provided on the second end of the spring, and the protrusion is located in the sliding grove; and
wherein a scale is provided on a surface of the first bottom plate away from the first side plates.

10. The mounting bracket according to claim 1 , further comprising a second spring arranged side by side with the spring or nested with the spring.

11. The mounting bracket according to claim 1 , wherein the lower arm covers the balancing mechanism from the bottom.

12. The mounting bracket according to claim 1 , wherein the upper arm covers the balancing mechanism from the top.

13. The mounting bracket according to claim 1 , wherein the balance mechanism is arranged inside the quadrilateral structure and an extension direction of the adjuster is the same as a stretching direction of the spring.

14. The mounting bracket according to claim 1 , wherein the balance mechanism further comprises an auxiliary elastic element connected to the quadrilateral structure.

15. The mounting bracket according to claim 14 , wherein the auxiliary elastic element is connected at an angle relative to the upper arm or the lower arm.

16. The mounting bracket according to claim 14 , wherein the auxiliary element is a spring or a gas spring.

17. The mounting bracket according to claim 16 , wherein the auxiliary elastic element is a gas spring having a first end connected to the base or to the lower arm and a second end connected to the upper arm or to the connecting head.

18. The mounting bracket according to claim 16 , wherein the auxiliary elastic element is a tension spring having a first end connected to the base or to the upper arm and a second end connected to the lower arm or to the connecting head.

19. The mounting bracket according to claim 14 , wherein the auxiliary elastic element is connected to the mounting part or the sliding part of the balance mechanism.

20. The mounting bracket according to claim 14 , wherein the auxiliary elastic element is connected to an outside of the quadrilateral structure.
