Description

Technical Field

[0001] This utility model relates to the field of electrical equipment bracket technology, and in particular to a VESA bracket for products such as monitors and all-in-one computers. Background Technology

[0002] Current monitors and all-in-one PCs typically use a lifting mechanism in conjunction with a VESA bracket for easy height and angle adjustment. The VESA (Video Electronics Standards Association) bracket contains VESA components (such as the VESA board and VESA cover), and the monitor is mounted and secured using these components. Current VESA brackets generally assemble and fix the VESA components to the support tube using fixing components and sliding blocks to form a height-adjustable structure, allowing for vertical rotation (forward and backward tilt) and screen rotation. However, screen rotation is only needed by a few users in specific scenarios. Therefore, traditional VESA brackets are relatively complex in structure and have many parts to achieve lifting, vertical rotation, and screen rotation functions. Furthermore, due to the inherent characteristics of plastic molds, core pulling and demolding require a draft angle; otherwise, demolding will be difficult or may damage the product. However, the draft angle results in a structure where the top dimension of the product cavity is larger than the bottom dimension. Since the sliding block has a fixed size, it fits tightly when lowered to the bottom and loosely when raised to the top, causing significant wobbling of the VESA component when raised to the top, resulting in poor stability. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a simple lifting display bracket with a simpler structure, more reasonable design, fewer parts, and greater stability and reliability.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a simple lifting display bracket, comprising a VESA plate, a fixing component, a support tube, and a constant force spring. The VESA plate and the fixing component are movably connected to form a structure that can rotate up and down. A sliding block is provided inside the support tube, and the fixing component is connected to the sliding block to form a lifting and sliding structure. The constant force spring is connected to the support tube and fixed to abut against the sliding block. The feature is that: an outwardly protruding elastic arm is provided on the upper side of the sliding block, and the elastic arm elastically abuts against the support tube to make the sliding block and the support tube form a tight fit structure; the middle area of ​​the VESA plate is bent backward to form a backwardly protruding folded ear, and the folded ear is connected to the fixing component.

[0005] Furthermore, rib strips are provided on the inner walls of both sides of the support tube, with the rib strips protruding towards the center. The spring arm is provided with a top lug, which abuts against the rib strip to achieve elastic contact between the spring arm and the support tube.

[0006] Furthermore, the spring arms extend upward from the left and right sides of the sliding block and protrude beyond the sides of the main body of the sliding block, while the top lugs protrude outward from the top of the spring arms. The spring arms and top lugs are an integral structure with the sliding block.

[0007] Furthermore, two bony strips are provided on each of the inner walls of the support tube, and the two bony strips abut against the top ear from the front and back positions of the sides respectively.

[0008] Furthermore, two folding ears extend backward from the middle of the VESA plate, and the two folding ears are connected and fixed to the fixing assembly through a fixing shaft.

[0009] Furthermore, a back plate is provided on the back of the VESA plate, which covers the VESA plate, the folding lugs, and the fixing shaft.

[0010] Furthermore, a back hole is provided on the back of the support tube. A locking screw is screwed into the back hole to lock the fixing component and the sliding block. A fixing screw is screwed into the back of the support tube to lock the force spring. A decorative piece is provided at the alignment point of the back hole to cover the back hole and the fixing screw.

[0011] Furthermore, the VESA board is equipped with a quick-release latch that can slide up and down. The quick-release latch is connected to a slide plate, which is installed on the back of the VESA board by a spring and covered by the back plate. The slide plate is connected to a latch that extends backward through the back plate.

[0012] Furthermore, a top cover is provided at the top of the support tube, which covers the top of the support tube.

[0013] This invention improves stability by providing spring arms on both sides of the top of the sliding block, which elastically abut against the support tube to maintain a tight fit. This addresses the issue of excessive wobbling when the sliding block reaches the top due to the support tube's internal shape being wider at the top than at the bottom. Furthermore, the conventional hinge rotating plate is eliminated; instead, the VESA plate is bent backward to form a folded lug for connection with the fixing component, saving parts, simplifying the structure, and reducing costs.

Detailed Implementation

[0021] In this embodiment, refer to Figures 1-6 The simple lifting display bracket includes a VESA plate 1, a fixing component 3, a support tube 5, and a constant force spring 6. The VESA plate 1 and the fixing component 3 are movably connected to form a structure that can rotate up and down. A sliding block 4 is provided inside the support tube 5. The fixing component 3 and the sliding block 4 are connected to form a lifting and sliding structure. The constant force spring 6 is connected and fixed to the support tube 5 and abuts against the sliding block 4. An outwardly protruding spring arm 41 is provided on the upper side of the sliding block 4. The spring arm 41 elastically abuts against the support tube 5 so that the sliding block 4 and the support tube 5 form a tight fit structure. The middle area of ​​the VESA plate 1 is bent backward to form a rearwardly protruding folding ear 11, which is connected to the fixing component 3.

[0022] Bone-position strips 51 are provided on the inner walls of both sides of the support tube 5. The bone-position strips 51 extend along the sliding direction of the sliding block 4 and protrude towards the center. The spring arm 41 is provided with a top lug 42, which abuts against the bone-position strip 51 to achieve elastic contact between the spring arm 4 and the support tube 5. This can increase the deformation range of the spring arm 4 and ensure that it still has sufficient tightness even when it rises to the highest point.

[0023] The spring arm 41 extends upward from the left and right sides of the sliding block 4 and protrudes beyond the main body of the sliding block 4. The top ear 42 protrudes outward from the top of the spring arm 41. The spring arm 41 and the top ear 42 are integral with the sliding block 4.

[0024] Two bone strips 51 are provided on each of the inner walls of the support tube 5. The two bone strips 51 abut against the top ear 42 from the front and back positions of the sides, which can improve stability from multiple directions.

[0025] Two folding lugs 11 extend backward from the middle of the VESA plate 1. The two folding lugs 11 are connected and fixed to the fixing component 3 via the fixing shaft 31, without the need for other adapter structures.

[0026] A back plate 2 is provided on the back of the VESA plate 1, which covers the VESA plate 1, the folding lug 11 and the fixing shaft 31, and serves as a protective measure.

[0027] A back hole 52 is provided on the back of the support tube 5. A locking screw 32 is screwed into the back hole 52 to lock and fix the fixing component 3 and the sliding block 4. A fixing screw 61 is screwed into the back of the support tube 5 to lock and fix the force spring 6. A decorative piece 8 is provided at the location aligned with the back hole 52 to cover the back hole 52 and the fixing screw 61. The decorative piece 8 is made of Mylar sheet, which can both conceal imperfections and secure the fixing component 3. Because the locking direction is consistent with the extension direction of the fixing component, the fixing component 3 and the sliding block 4 can be more securely joined.

[0028] A quick-release latch 12 that can slide up and down is provided on the VESA board 1. The quick-release latch 12 is connected to a slide plate 13. The slide plate 13 is installed on the back of the VESA board 1 by a spring (not shown) and is covered by a back plate 2. The slide plate 13 is connected to a latch 14, which extends backward through the back plate 2. The display device is fixed by the quick-release latch 12 engaging with the hook on the top of the VESA board. To disassemble, the latch 14 is pushed down, and the quick-release latch 12 releases the display device. This quick-release structure has two advantages: first, it saves on tapping and stepped screws, thus saving manufacturing costs; second, the slide plate backs onto the VESA board 1, which can provide full-surface support for force distribution. Compared with the conventional method of partial support on both sides, this structure is less prone to breakage and has higher reliability.

[0029] A top cover 53 is provided at the top of the support tube 5, which covers the top of the support tube 5 and the sliding block 4 and other mechanisms.

[0030] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
