Description

Technical Field

[0001] This utility model relates to the field of electronic device stand technology, and in particular to a foldable laptop stand. Background Technology

[0002] With the increasing popularity of mobile work and entertainment, foldable support devices such as laptop stands have become widely used because they improve upon the limitations of non-foldable devices, which are inconvenient to carry and store. One of the core functions of these devices is their ability to be stably and conveniently adjusted and folded at multiple angles.

[0003] Existing laptop stands mostly use mechanical locking mechanisms to adjust the angle. When adjusting, the adjustment lever must be manually locked into the corresponding position, which cannot achieve "lift and adjust". This results in a poor user experience and is cumbersome and inconvenient to operate. In addition, current laptop stands are bulky, non-foldable, and inconvenient to carry and store. Utility Model Content

[0004] The purpose of this utility model is to provide a foldable laptop stand to solve the technical problems mentioned in the background art, which require manually locking the adjustment lever into the corresponding position when adjusting the angle of the laptop stand, making it impossible to achieve "lift and adjust" and making it bulky and not foldable and portable.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a foldable laptop stand, comprising: A pair of symmetrically arranged support components, each including a rotatably connected first sub-rod and second sub-rod; a foldable crossbar assembly connecting the two support components, the foldable crossbar assembly including a first crossbar and a second crossbar; the rotatable connection ends of the first and second sub-rods are provided with meshing gears to maintain synchronous movement of the two sub-rods during unfolding or folding; one end of the first crossbar is rotatably connected to one of the support components, and the other end is provided with at least two first engaging protrusions; one end of the second crossbar is rotatably connected to the other support component, and the other end is provided with at least two second engaging protrusions; the first and second engaging protrusions are respectively provided with coaxial first through holes and second through holes; the first and second crossbars are rotatably connected, and when connected, the first and second engaging protrusions are arranged vertically and form a hollow hole in the middle; a rotating shaft passes through the first and second through holes in sequence, rotatably connecting and fixing the first and second crossbars together, so that the first and second crossbars can be folded around the rotating shaft.

[0006] Preferably, the bottom of the second sub-rod is snapped or integrally formed with a bracket for supporting the laptop computer.

[0007] Preferably, the bracket is provided with a protrusion to prevent the computer from slipping when placed on it.

[0008] Preferably, the meshing gears include a first sector gear disposed at the end of the first sub-rod and a second sector gear disposed at the end of the second sub-rod. The first sector gear and the second sector gear have the same outer diameter, the same number of teeth, and a fixed center distance to ensure that the first sub-rod and the second sub-rod always have opposite angles and the same amplitude during rotation.

[0009] Preferably, it also includes a magnetic fixing base, which has a third through hole through both sides. The fixing base is embedded in the hollow hole, and the third through hole is coaxially distributed with the first through hole and the second through hole so that the three can be rotatably connected and fixed by the rotating shaft.

[0010] Preferably, the upper end of the first sub-rod is provided with a first groove and a second groove, and a fixing block is provided on the surface of the first groove.

[0011] Preferably, it also includes a support arm and a bracket arm. The top end of the support arm is rotatably connected to the first sub-rod and embedded in the second groove. The support arm is also provided with a slot. The top end of the support arm is rotatably connected to the first sub-rod and embedded in the first groove. The support assembly can be adjusted and fixed up and down along the support arm by engaging the bottom end of the support arm with the slot. When not needed, both the support arm and the bracket arm can be stored in the first groove.

[0012] Preferably, it further includes a torsion spring and a first rotating shaft. The torsion spring has a middle winding portion, a first torsion arm, and a second torsion arm. The middle winding portion is fixedly wound around the first rotating shaft. The free end of the first torsion arm serves as a positioning end and abuts vertically against the surface of the fixed block. The free end of the second torsion arm serves as a pressure end and continuously and elastically abuts against the outer edge of the first groove. When the positioning end abuts vertically against the surface of the fixed block, the pressure end applies pressure to the outer edge, working together with the positioning end to constrain the displacement of the first groove, thereby locking the relative angle between the support arm and the bracket arm.

[0013] Preferably, both the first sub-rod and the second sub-rod are provided with silicone pads at their upper ends.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention features meshing gears at the connection ends of the first and second sub-stems and engaging protrusions at the connection ends of the first and second crossbars, allowing for folding during transport. Furthermore, a torsion spring is fitted onto the first rotating shaft, with the free end of the first torsion arm serving as a positioning end, perpendicularly abutting the surface of the fixing block, and the free end of the second torsion arm serving as a pressure end, continuously and elastically abutting the outer edge of the first groove. This achieves locking of the relative angle between the support arm and the bracket arm, eliminating the need for manual adjustment during use. Attached Figure Description

The free end of the first torsion arm 604 of the torsion spring serves as the positioning end and abuts vertically against the surface of the fixing block 1014. The free end of the second torsion arm 605 of the torsion spring serves as the pressure end and continuously elastically abuts against the outer edge of the first groove 1012. When the positioning end abuts vertically against the surface of the fixing block 1014, the pressure end applies pressure to the outer edge, working together with the positioning end to constrain the displacement of the first groove 1012, thereby locking the relative angle between the support arm 5 and the support arm 6.
