A four-bar linkage support arm structure as shown in fig. 1-3, includes a connecting base 3, a top base 4, an outer shell 5, a fixing frame 6 and a linear telescopic mechanism. The both ends of shell body 5 and mount 6 are equallyd divide and are articulated respectively on connecting seat 3 and footstock 4, and shell body 5 has the chamber that holds, and mount 6 is arranged in and is held the intracavity. Two ends of the linear telescopic mechanism are respectively hinged on the connecting seat 3 and the fixing frame 6 and used for supporting the fixing frame 6.

Compared with the prior art, the four-connecting-rod supporting arm structure has the advantages that the outer shell 5 is adopted to replace a long arm of the traditional four-connecting-rod structure, the outer shell 5 can play the roles of the long arm and the outer shell in the four-connecting-rod structure, the structure of the four-connecting-rod supporting arm is simplified, and the four-connecting-rod supporting arm structure is convenient to assemble and low in production cost.

The rotation principle of the four-bar linkage supporting structure is as follows: because the two ends of the outer shell 5 and the fixing frame 6 are respectively hinged on the connecting seat 3 and the top seat 4, the four hinged points of the outer shell 5 and the fixing frame 6 on the connecting seat 3 and the top seat 4 are connected on the same plane to form a parallelogram structure when seen from the side surface of the four-bar supporting arm. The connecting line between two hinge points on the connecting seat 3 can be regarded as a first side of the parallelogram structure, the connecting line between the hinge points on the top seat 4 can be regarded as a second side of the parallelogram structure, the first side and the second side are oppositely arranged, and the outer shell 5 and the fixing frame 6 are respectively regarded as the other two opposite third sides and fourth sides of the parallelogram structure. When the outer shell 5 rotates relative to the connecting seat 3, the fixing frame 6 is driven by the parallelogram structure to move relative to the connecting seat 3, so that the position and the direction of the top seat 4 relative to the connecting seat 3 are adjusted; meanwhile, the linear telescopic mechanism provides support for the fixing frame 6, so that the top seat 4 can hover at any position.

In a preferred embodiment of this embodiment, the linear retraction mechanism employs a spring assembly 7. One end of the spring assembly 7 is mounted on the connecting seat 3 through a first hinge seat (not shown), and the other end is mounted on one end of the fixing frame 6 opposite to the connecting seat 3 through a second hinge seat 16. When the outer shell 5 and the fixing frame 6 rotate relative to the connecting seat 3, the rotation angles of the spring assemblies 7 are different at different angles, and the elastic force value is changed accordingly. By adjusting the positions of the first hinge seat and the second hinge seat 16 at the two ends of the spring assembly 7, the upper support arm (the upper support arm 2 in fig. 6) can be in a stress balance state at any angle, that is, the top seat 4 can hover at any position relative to the connecting seat 3; specifically, the spring assembly 7 in the present embodiment may be a gas spring assembly or a compression spring assembly, or the like. In other embodiments, the linear telescopic mechanism can be replaced by a linear push rod, an air cylinder or a hydraulic cylinder.

In this embodiment, one end of the outer housing 5 is pivotally connected to the connecting base 3 through a first pivot 8, and the other end of the outer housing 5 is pivotally connected to the top base 4 through a second pivot 9; one end of the fixing frame 6 is pivoted to the connecting base 3 through a third pivot 10, and the other end of the fixing frame 6 is pivoted to the top base 4 through a fourth pivot 11. The connecting lines of the central axes of the first pivot 8, the second pivot 9, the third pivot 10 and the fourth pivot 11 on the same plane form a parallelogram. The fixing frame 6 and the outer shell 5 are respectively connected between the connecting seat 3 and the top seat 4 through pivots, so that the top seat 4 can be lifted or lowered relative to the connecting seat 3, and the assembly operation is more convenient. In other embodiments, the outer housing 5 and the fixing frame 6 can also be directly rotatably mounted on the connecting seat 3 and the top seat 4 at two ends without being connected with each other through a pivot.

In the present embodiment, the lengths of the first pivot 8 and the second pivot 9 are the same, and the lengths of the third pivot 10 and the fourth pivot 11 are the same and smaller than the lengths of the first pivot 8 and the second pivot 9. By such arrangement, the outer shell 5 can completely cover the two ends of the third pivot 10 and the fourth pivot 11 in the accommodating cavities therein, so that the exposure of the pivots is reduced, and the integral aesthetic property is better.

In the present embodiment, the outer housing 5 includes an upper housing 51 and a lower housing 52, and the upper housing 51 and the lower housing 52 are coupled by a plurality of snap structures 15 on the outer periphery. The fastening structure 15 includes a hook integrally formed on the upper housing 51 and extending toward the lower housing 52, and a latch integrally formed on the inner wall of the lower housing 52, the latch is engaged with the hook at a corresponding position, so as to connect the upper housing 51 and the lower housing 52 as a whole. Go up casing 51 and lower casing 52 and adopt the mode of buckle cooperation connection, need not to use the screw to fix, it is more convenient to assemble, and the whole aesthetic property of shell body 5 is also better. Of course, the outer housing 5 may also be a simplified structure including only the upper housing 51, without the lower housing 52 and the snap structure 15.

In this embodiment, the fixing frame 6 is a sheet metal part with a U-shaped structure, and is used for providing support strength for the four-bar linkage support arm structure. The sheet metal component includes roof 61 and two lateral walls 62 of integrative connection in the relative both sides of roof 61, and the relative both ends of two lateral walls 62 pin joint respectively in connecting seat 3 and footstock 4.

In this embodiment, the connecting seat 3 is provided with a limiting structure 17, and the upper surface of the limiting structure 17 is horizontally arranged. Specifically, the limiting structure 17 is a block structure integrally formed on two opposite side surfaces of the connecting seat 3. When the fixing frame 6 rotates to a horizontal position, the lower end surfaces of the two side walls 62 of the fixing frame 6 are abutted against the upper surface of the limiting structure 17, so that the top seat 4 is prevented from being lower than the connecting seat 3 due to the fact that the rotating angle of the fixing frame 17 is too large.

Specifically, as shown in fig. 4 and 5, the first pivot 8 and the second pivot 9 are both configured such that the hollow pin 12 and the pin cap 13 are engaged with each other. The end parts of the hollow pin 12 and the pin cap 13 are both sleeved with a protective sleeve 14, and the protective sleeve 14 is a plastic part. The plastic part can reduce the exposure of the end parts of the hollow pins 12 and the pin caps 13, reduce the influence of the external environment on the hollow pins 12 and the pin caps 13, and also ensure that the integral structure of the support arm has better aesthetic property.
