Description

Technical Field

[0001] This utility model relates to the field of foldable tablet computer stand technology, and in particular to a foldable tablet computer stand structure. Background Technology

[0002] With the rapid development of technology, tablet computers have become widespread and integrated into all aspects of people's lives, becoming an extremely convenient tool for communication and interaction. However, like any emerging technology, tablet computers have also revealed some problems that urgently need to be solved during use. One of the most prominent issues is the lack of a matching stand, which makes it difficult for users to find a suitable placement angle when watching videos, conducting video conferences, or performing office work, thus affecting the user experience. At the same time, while the slim and lightweight design of tablet computers makes them easy to carry, it also brings the inconvenience of holding them in your hand. Holding them for a long time can easily cause hand fatigue, especially in mobile scenarios, which further increases the difficulty of use.

[0003] A tablet stand is a device specifically designed to support tablets, incorporating ergonomic principles to provide users with a comfortable and convenient experience. These stands typically feature multiple adjustment functions, including flexible adjustments for height, angle, and tilt, to meet diverse user needs in different scenarios. Whether for work, study, or entertainment, a tablet stand provides stable support and an optimal viewing angle, thereby improving efficiency and comfort.

[0004] While the aforementioned technologies enable adjustment of the tablet's height and angle, under extreme usage conditions, such as prolonged bending at a large angle or exposure to significant external forces, the connecting components at the folding joint may loosen due to fatigue. Therefore, a folding stand structure for tablets is proposed to address this issue. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides a foldable stand structure for tablet computers, which aims to solve the problem that the connecting parts at the folding joint may loosen due to fatigue when the tablet is bent at a large angle for a long time or subjected to large external forces in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a foldable tablet computer stand structure, including a support plate, a magnetic block fixedly connected to the surface of the support plate, a fixing plate fixedly connected to the top of the support plate, a pen groove on the front wall of the fixing plate, a groove on the rear wall of the fixing plate, a bracket rotatably connected to the rear wall of the support plate, stabilizing components provided at the front and rear ends of the bracket, a first rotating shaft rotatably connected to the rear end of the bracket, an mounting block rotatably connected to the outer wall of the first rotating shaft, a base plate fixedly connected to the bottom of the mounting block, a rotating base plate detachably connected to the bottom of the base plate, a base rotatably connected to the bottom of the rotating base plate, and a disassembly component provided at the bottom of the mounting block;

[0007] The stability component includes a pawl, the outer wall of which is engaged with a ratchet, a rotating column is rotatably connected inside the pawl, a vertical plate is rotatably connected to the outer wall of the rotating column, and a groove is provided on the top of the rotating base plate.

[0008] As a further description of the above technical solution:

[0009] The stability component includes a second rotating shaft, the outer wall of which has a limiting groove, and a limiting block is engaged inside the limiting groove. The rear wall of the limiting block is elastically connected to the top of the bracket by a second spring.

[0010] As a further description of the above technical solution:

[0011] The disassembly assembly includes a nut, and a fixing block is detachably connected to the bottom of the second rotating shaft. The fixing block is internally threaded with a bolt, and the outer wall of the nut is threadedly connected to the inside of the rotating base plate.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the upright plate is slidably connected to the inside of the groove.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the second rotating shaft is rotatably connected to the inside of the bracket.

[0016] As a further description of the above technical solution:

[0021] The outer wall of the nut is threaded to the inside of the base plate, the outer wall of the bolt is threaded to the inside of the second rotating shaft, and the outer wall of the pawl engages with the outer wall of the ratchet.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, by setting a first spring, ratchet, and pawl, when the bracket needs to be rotated, the bracket is lifted upward, so that the pawl and rotating column are lifted upward when rotating, releasing the limiting block and allowing the limiting block to reset under the elastic action of the second spring and engage with the limiting groove, thereby limiting the support plate. This solves the risk of fatigue and loosening of the connecting parts at the folding joint when maintaining a large angle bend for a long time or bearing a large external force.

[0024] 2. In this utility model, by setting bolts, nuts, and fixing blocks, a fixing block is set on the rear wall of the support plate, and then the second rotating shaft is connected to the fixing block by bolts. The base plate connected to the bracket is connected to the rotating base plate by nuts. This solves the problem that when a certain component is damaged, the whole thing needs to be scrapped, resulting in a waste of resources. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of a foldable tablet computer stand structure, including a support plate 1. A magnetic block 2 is fixedly connected to the surface of the support plate 1. The force of the magnetic block 2 ensures the tablet computer remains stable on the support plate 1, preventing it from shaking or falling. A fixing plate 4 is fixedly connected to the top of the support plate 1. A pen slot 5 is provided on the front wall of the fixing plate 4. The pen slot 5 is located on the stand 9, allowing the pen to be within the same field of vision and operating range as the computer, making it easily accessible without having to search for it on the desktop or elsewhere. This promptly meets writing needs and improves work and study efficiency. The rear wall of 4 has a groove 11. The rear wall of the support plate 1 is rotatably connected to the bracket 9. The front and rear ends of the bracket 9 are provided with stability components 7. The rear end of the bracket 9 is rotatably connected to a first rotating shaft 10. The outer wall of the first rotating shaft 10 is rotatably connected to an installation block 12. When the bracket 9 is rotated, the bracket 9 is lifted upward. The ratchet 702 will move synchronously and rotate upward. The bottom of the installation block 12 is fixedly connected to a base plate 13. The bottom of the base plate 13 is detachably connected to a rotating base plate 6. The bottom of the rotating base plate 6 is rotatably connected to a base 3. The bottom of the installation block 12 is provided with a disassembly component 8.

[0033] The stability component 7 includes a pawl 701. The support plate 1 rotates and folds backward. When the bracket 9 is to be folded, the upright plate 703 slides outward within the slide groove 16, disengaging the pawl 701 and ratchet 702, releasing their engagement. The bracket 9 is then folded downward. This addresses the problem of the connecting parts at the folding joint potentially loosening due to fatigue when subjected to prolonged large-angle bending or significant external force. The outer wall of the pawl 701 engages with the ratchet 702, and the internal part of the pawl 701 is rotatably connected to a rotating post 704. The pawl 701 is a component that actuates the ratchet 702 in intermittent motion. The pawl 701 is driven by a connecting rod to reciprocate, thereby driving the ratchet 702 to move in one direction. The structural component used to lock the ratchet 702, allowing it to move in one direction and lock in the reverse direction, has a vertical plate 703 rotatably connected to the outer wall of the rotating column 704. The top of the rotating base plate 6 has a sliding groove 16. The stability component 7 includes a second rotating shaft 706, with a limit groove 708 on its outer wall. When the support plate 1 is rotated, the limit block 705 is manually released from the limit groove 708. Because the support plate 1 and the second rotating shaft 706 are connected, the rotation of the second rotating shaft 706 at the top of the bracket 9 allows the support plate 1 to rotate. When it rotates to a certain position, the limit block 705 is released, allowing it to reset under the elastic action of the second spring 707 and engage with the limit groove 708. The limit block 705 is engaged inside the limit groove 708, and the rear wall of the limit block 705 is elastically connected to the inside of the top of the bracket 9 through the second spring 707.

[0034] Reference Figure 2 - Figure 4The disassembly assembly 8 includes a nut 83. A fixing block 81 is detachably connected to the bottom of the second rotating shaft 706. A bolt 82 is threaded into the inside of the fixing block 81. The outer wall of the nut 83 is threaded into the inside of the rotating base plate 6. The outer wall of the upright plate 703 is slidably connected to the inside of the slide groove 16. A fixing block 81 is provided on the rear wall of the support plate 1 and connected to it. A threaded hole is opened on the outer wall of the fixing block 81, and a threaded hole is also opened inside the second rotating shaft 706. The second rotating shaft 706 is then connected to the fixing block 81 by bolts 82. The base plate 13, which is connected to the bracket 9, is then connected to the rotating base plate 6 by the nut 83. When a component is damaged, it is necessary to... The entire structure is scrapped, resulting in a waste of resources. The outer wall of the second rotating shaft 706 is rotatably connected to the inside of the bracket 9, and the outer wall of the first rotating shaft 10 is rotatably connected to the inside of the ratchet 702. One end of the second spring 707 is fixedly connected to the rear wall of the limit block 705, and the other end of the second spring 707 is fixedly connected to the inside of the top of the bracket 9. The second spring 707 resets the limit block 705. A slot is opened inside the top of the bracket 9, and the outer wall of the limit block 705 is slidably connected to the inside of the slot. The outer wall of the nut 83 is threadedly connected to the inside of the base plate 13, the outer wall of the bolt 82 is threadedly connected to the inside of the second rotating shaft 706, and the outer wall of the pawl 701 is engaged with the outer wall of the ratchet 702.

[0035] Working principle: In use, when the bracket 9 is to be rotated, lifting the bracket 9 upwards will cause the ratchet 702 to rotate and lift simultaneously. The bracket 9 stops when it reaches a certain position, and the pawl 701, which meshes with the ratchet 702, limits the ratchet 702, thus limiting the bracket 9 connected to the first rotating shaft 10. When the support plate 1 is to be rotated, manually disengaging the limiting block 705 from the limiting groove 708. Because the support plate 1 is connected to the second rotating shaft 706, the rotation of the second rotating shaft 706 at the top of the bracket 9 allows the support plate 1 to rotate. Once a certain position is reached, releasing the limiting block 705 allows it to reset under the elastic action of the second spring 707 and engage with the limiting groove 708, thus limiting the support plate 1. When the support plate 1 is to be folded, the limiting block 705 is... After disengaging from the limiting groove 708, the support plate 1 is rotated and folded backward. When the bracket 9 is to be folded, the upright plate 703 is slid outward in the slide groove 16 to disengage the pawl 701 and ratchet 702. Then the bracket 9 is folded downward. This solves the problem that the connecting parts at the folding joint may loosen due to fatigue when the bracket is bent at a large angle for a long time or subjected to large external forces. A fixing block 81 is set on the rear wall of the support plate 1 and connected to it. A threaded hole is opened on the outer wall of the fixing block 81. At the same time, a threaded hole is opened inside the second rotating shaft 706. Then, the second rotating shaft 706 is connected to the fixing block 81 by bolts 82. Then, the base plate 13 connected to the bracket 9 is connected to the rotating base plate 6 by nuts 83. This solves the problem that when a certain part is damaged, the whole thing needs to be scrapped, resulting in a waste of resources.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
