Description

Technical Field

[0001] This utility model relates to the field of electronic device bracket technology, and in particular to a laptop computer bracket. 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 such devices is their ability to be stably and conveniently adjusted at multiple angles and reliably locked.

[0003] Most existing laptop stand angle adjustment methods use mechanical locking to lock the angle. When adjusting, the adjustment lever must be manually locked into the corresponding locking position, which cannot achieve "lift and adjust". This results in a poor user experience and is cumbersome, inconvenient and not secure. Utility Model Content

[0004] The purpose of this utility model is to provide a laptop stand that solves the technical problem mentioned in the background art that when adjusting the angle of a laptop stand, the adjustment lever must be manually locked into the corresponding position, making it impossible to achieve "adjustment upon lifting".

[0005] To achieve the above objectives, this utility model provides the following technical solution: A laptop stand, comprising: a stand base, a support arm, a support arm, and an "X"-shaped folding frame arranged symmetrically on the left and right sides. The stand base has several slots in its middle section, an arc-shaped abutment at its front end, and a folding slot behind the arc-shaped abutment. The stand base also has a folding head at its front end, which is adapted to engage with the folding slot. The support arm has a circular through hole, a stepped groove, and a sliding groove from front to back. The front end of the "X"-shaped folding frame is fixedly connected to the circular through hole, and its rear end is movably embedded in the sliding groove. The stepped groove has at least two positioning stepped surfaces distributed along the rotation direction. A connecting component is also provided within the stepped groove. The top end of the support arm is rotatably connected to the sliding groove via the connecting component. The bottom end of the support arm is movably engaged with several slots within the stepped groove. The connecting assembly includes a rotating shaft and a torsion spring. The top end of the support arm is rotatably connected via the rotating shaft. A torsion spring is sleeved on the rotating shaft. The torsion spring has a central winding portion, a first torsion arm, and a second torsion arm. The central winding portion is fixedly wound around the rotating shaft. The first torsion arm is a short arm, with its free end serving as a positioning end, selectively abutting against the positioning stepped surface. The second torsion arm is a long arm, with its free end serving as a pressure end, continuously and elastically abutting against the outer edge of the stepped groove. When the positioning end abuts against a positioning stepped surface, the pressure end applies pressure to the outer edge, working in conjunction with the positioning end to constrain the displacement of the stepped groove, thereby locking the relative angle between the support arm and the bracket arm.

[0006] Preferably, the length of the first torsion arm is configured such that when its positioning end abuts against the positioning step surface, the first torsion arm is in a relaxed or slightly stressed state, and the length of the second torsion arm is configured such that its pressure end always maintains a preset elastic pressure on the outer edge.

[0007] Preferably, the positioning end of the first torsion arm is provided with a ball head or a wedge head.

[0008] Preferably, the stepped groove is an arc-shaped groove formed on the support arm, and the outer edge is one side of the groove wall of the arc-shaped groove.

[0009] Preferably, the contact point between the pressure end of the second torsion arm and the outer edge is a line contact or a surface contact.

[0010] Preferably, it also includes a fixed shaft and a plastic tube, and the bottom end of the folding head is rotatably connected and embedded in the folding slot through the fixed shaft and the plastic tube.

[0011] Preferably, the support arm is engaged with the slot at the bottom of the support arm and can be adjusted and fixed up and down along the support base. When not needed, the support arm can be stored in the support arm slide groove.

[0012] Preferably, the "X"-shaped folding frame extends and folds by sliding its rear end along the slide rail up and down, causing the support base and the support arm to move left and right.

[0013] Preferably, silicone pads are provided at the rear end of the bracket base, the arc-shaped abutment at the front end of the bracket base, and the upper end of the bracket arm.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention utilizes a torsion spring mounted on a rotating shaft. The first torsion arm of the torsion spring serves as the positioning end, abutting against the positioning stepped surface, while the second torsion arm of the torsion spring serves as the pressure end, continuously and elastically abutting against the outer edge of the stepped groove. When the positioning end abuts against the positioning stepped surface, the pressure end applies pressure to the outer edge, working in conjunction with the positioning end to constrain the displacement of the stepped groove, thereby locking the relative angle between the support arm and the bracket arm. No manual adjustment is required during use; the "lift and adjust" method is more convenient, the locking is more secure, and the user experience is enhanced. Attached Figure Description

Arm 2 has a circular through hole 302, a stepped groove 303, and a rectangular slide 304 from front to back. The front end of the "X"-shaped folding frame 4 is hinged to the circular through hole 302 by a damping plate 7 and a pin 8. The rear end is hinged to a damping plate 7 and a pin 8, with the pin movably embedded in the slide 304 to drive the support base 1 and the support arm 3 to move left and right to achieve extension and folding. The stepped groove 303 has at least two positioning stepped surfaces 3031 distributed along the rotation direction, and the stepped groove is also provided with a connecting Component 9, the top end of the support arm 2 is rotatably embedded in the stepped groove 303 via the connecting component 9, and the bottom end is movably engaged with several slots 101 for vertical adjustment and fixation. The connecting component 9 includes a rotating shaft 901 and a torsion spring 902. The top end of the support arm 2 is rotatably connected via the rotating shaft 901. The torsion spring 902 is sleeved on the rotating shaft 901. The torsion spring 902 has a middle winding part 9021, a first torsion arm 9022 and a second torsion arm 9023. The middle winding part 9021 is connected to the rotating shaft 902. 01 Fixed connection, the first torsion arm 9022 is a short arm with its free end serving as the positioning end, selectively abutting against the positioning stepped surface 3031, the second torsion arm 9023 is a long arm with its free end serving as the pressure end, continuously elastically abutting against the outer edge of the stepped groove 303, wherein, when the positioning end abuts against a positioning stepped surface 3031, the pressure end applies pressure to the outer edge, working together with the positioning end to constrain the displacement of the stepped groove 303, thereby achieving the locking of the relative angle between the support arm 3 and the support arm 2.

[0019] In this embodiment, preferably, the length of the first torsion arm 9022 is configured such that when its positioning end abuts against the positioning step surface 3031, the first torsion arm 9022 is in a state of relaxation or slight force, and the length of the second torsion arm 9023 is configured such that its pressure end always maintains a preset elastic pressure on the outer edge.

[0020] In this embodiment, preferably, the positioning end of the first torsion arm 9022 is spherical.

[0021] In this embodiment, preferably, the stepped groove 303 is an arc-shaped groove formed on the support arm 3, and the outer edge is one side of the groove wall of the arc-shaped groove.

[0022] In this embodiment, preferably, the contact point between the pressure end of the second torsion arm 9023 and the outer edge is a line contact or a surface contact, so as to provide a more continuous and stable friction force, making the damping feel more uniform and smooth during the adjustment process.

In this embodiment, the first torsion arm 9022 is a short arm with its free end serving as the positioning end. The positioning end of the first torsion arm 9022 is a wedge head 11. The wedge head 11 has a guiding inclined surface 1101 and a stop surface 1102. When it is responsible for one direction (such as the bracket opening direction), it converts the pressure from the torsion spring 902 into a component force parallel to the inclined surface, helping it to "climb" the step and selectively abut against the positioning step surface 3031 to achieve effortless and smooth operation. When (such as the bracket closing direction), it forms a large area of ​​contact or line contact with the vertical surface of the step. Due to the steep angle, the force from the opposite direction will only press it tighter, generating mechanical self-locking and achieving stable locking. The second torsion arm 9023 is a long arm with its free end serving as a pressure end, continuously and elastically abutting against the outer edge of the stepped groove 303. When the positioning end abuts against a positioning stepped surface 3031, the pressure end applies pressure to the outer edge, working together with the positioning end to constrain the displacement of the stepped groove 303, thereby locking the relative angle between the support arm 3 and the support arm 2, and also achieving coordinated locking of the long and short arms.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and inventive concept of the present utility model, should be included within the protection scope of the present utility model.
