Description

Support tripod structure

This creation is about a supporting tripod structure, especially a kind of structure that is assembled on the back side of a planar electronic device, so that the planar electronic device can perform up and down and pitching movements at the same time, and the adjustment angle can be increased.

Currently common planar electronic devices such as tablet computers, AIO computers or flat-panel displays are mostly supported by a support tripod to allow the planar electronic devices to stand. Usually, at least one hinge is provided between the planar electronic device, the support stand and a base, so that the planar electronic device can have the function of pitch adjustment relative to the base, and the planar electronic device can be adjusted according to the size of the user. The difference is to quickly adjust the position and height of the display, which is suitable for watching the screen or convenient for users to touch and operate. However, common support tripods cannot allow the planar electronic device to rise and fall and move back and forth at the same time, and since the support tripod is often presented in a "cantilever" structure, in order to resist the deviation of the center of gravity and stabilize the planar electronic device , that is, the base needs to be enlarged to increase the space occupied by the work table.

In order to improve the above problems, as shown in the "multi-link support device" of the utility model patent No. CN216361256U of the People's Republic of China, a solution is provided, which mainly includes a load mounting seat, a lifting unit and a base. Each connecting arm in the lifting unit uses at least three long connecting rods to form two sets of four-bar linkage structures, one of which is a parallel four-bar linkage structure and the other is a non-parallel four-bar linkage structure. Use the length difference of the non-parallel four-bar linkage to create a rotational differential ratio to compensate the angular offset of the load during the lifting process, so that the load can maintain a linear motion track of straight lifting and the load will not produce a center of gravity deviation during lifting. shift phenomenon. However, based on the joint operation of two groups of four-link structures, although the size of the base can be minimized to avoid occupying the space of the work table, the overall structure is complex, and the angle of load adjustment is limited. After the relative bending angle of the rod structure becomes smaller, the bending part will be extended backward to increase the overall volume, thereby occupying a larger space behind the desktop.

By setting up a slide rail assembly and two sets of structures that can be rotated and positioned separately, the relationship between the parts can be simplified. The structure and shape are convenient for assembly and use, and save manufacturing costs; it can make the planar electronic device slide back and forth, and do up and down and pitch movements while sliding, so that the adjustment angle of the planar electronic device can be increased to meet the use It can meet the touch control requirements of users; at the same time, it can replace the traditional four-link structure to effectively reduce the overall volume, thereby reducing the occupied desktop space.
