Description

Technical Field

[0001] This utility model relates to the field of tablet computer support technology, specifically a novel support and fixing bracket for tablet computers. Background Technology

[0002] Traditional tablet stands face multiple pain points in use. On smooth surfaces such as glass, ceramic tiles, and metal, the stands often slip and fall off due to aging suction cups or damage to the device's edges from the clamp structure, affecting stability and potentially damaging the device. Regarding angle adjustment, traditional stands have a limited range of adjustment, and after adjustment, they are prone to springing back due to structural loosening, making it difficult to maintain the precise angle required for different scenarios such as watching movies, drawing, and writing, significantly reducing the user experience. Insufficient anti-slip design causes the tablet to slide and wear on the stand, potentially accelerating device wear over time. Compatibility issues are also prominent; different sizes or models of tablets require dedicated stands, increasing user selection costs and inconvenience. Furthermore, the installation process is cumbersome, requiring professional tools or specific skills, making it difficult for ordinary users to operate independently. Over time, problems such as material aging and wear on the adjustment mechanism gradually emerge, leading to poor adjustment, reduced stability, and significantly decreased durability, making it difficult to meet the needs of continuous and stable use. Therefore, this project was developed to address these issues through in-depth research. Summary of the Invention

[0003] To achieve the above objectives, this utility model provides the following technical solution: A novel support and fixing frame for a tablet computer, comprising a support and fixing frame, on which a limiting squeezer and an adsorption fixing device are installed. The adsorption fixing device includes a U-shaped limiting block, and toothed support blocks are respectively installed on the U-shaped limiting block and the support and fixing frame. A pair of toothed support blocks intersect each other, and an angle shaft is installed on the pair of toothed support blocks. A pair of extended rotation grooves are provided on the support and fixing frame, and a pair of telescopic limiting grooves are provided on the U-shaped limiting block. A telescopic slider is installed on the inner side of the telescopic limiting groove, and the cross-section of the telescopic limiting groove and the telescopic slider is convex. The telescopic slider is equipped with a concave bearing block. An I-shaped rod is installed on the concave bearing block and the extended rotating groove. Two pairs of negative pressure convex slots are provided on the U-shaped limiting block. A negative pressure shaft barrel and a negative pressure disc are located inside the negative pressure convex slots. A negative pressure threaded tube is provided on the negative pressure shaft barrel. A negative pressure threaded rod is installed inside the negative pressure threaded tube. The negative pressure disc is connected to the negative pressure threaded rod. A negative pressure stretching disc is installed on the negative pressure threaded rod. A negative pressure ring is installed on the negative pressure stretching disc. A negative pressure disc ring is installed on the negative pressure threaded tube. The negative pressure stretching disc is installed inside the negative pressure convex slot through a linear bearing.

[0008] Preferably, the inner side of the support frame is provided with a cooling fan and a charging port. Beneficial effects

[0009] This utility model provides a novel support and fixing bracket for tablet computers. It offers the following advantages: The novel support and fixing bracket employs a negative pressure adsorption system. A negative pressure disc drives a threaded structure, causing the negative pressure stretching disc to extend and retract along the shaft. Combined with a double-lip sealing ring, this creates a stable negative pressure, making it suitable for various surfaces such as glass, wood, and ceramic tiles, thus solving the problem of traditional brackets easily slipping and falling off. The angle adjustment mechanism, through a telescopic slider linked to an I-beam, pushes a toothed support block to rotate around the axis. Combined with an extension spring and extension ball mechanical limit and multi-level positioning holes, it achieves precise and wide-range angle adjustment and prevents rebound, meeting the needs of scenarios such as watching movies, drawing, and writing. Three pairs of stretching and compressing blocks, together with spring columns, form an elastic clamping force. Combined with a nano-anti-slip coating, it effectively prevents the device from sliding and wearing. The modular design adapts to different sizes and models of devices, improving compatibility. Wear-resistant materials, low-friction linear bearings, and a cooling fan, along with other safety redundancy designs, ensure smooth adjustment and long-term durability, achieving a comprehensive improvement in portability, adaptability, and safety.

[0015] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0017] Please see Figure 1-4 Traditional tablet stands are prone to slipping and falling off on smooth surfaces (such as glass, tiles, and metal). They rely on suction cups or clips, but these structures are susceptible to aging and failure, and damage to the edges of the device. The angle adjustment range is limited and the stands tend to bounce back after adjustment, making it difficult to meet the needs of various scenarios such as watching movies, drawing, and writing. Insufficient anti-slip design leads to slipping and wear on the device, and poor compatibility requires dedicated stand models. The installation process is cumbersome, and the stands are prone to aging and wear after long-term use, resulting in insufficient durability.

[0018] Therefore, this application protects a novel support bracket for a tablet computer. By placing the U-shaped limiting block 2 in the support position, rotating the negative pressure disc 12 causes the negative pressure disc 12 to drive the negative pressure threaded tube 13 on it. The negative pressure threaded tube 13 drives the inner negative pressure threaded rod 14, which in turn drives the negative pressure stretching disc 15 on it. This causes the negative pressure stretching disc 15 to stably extend and retract along the inner side of the negative pressure shaft barrel 11. The negative pressure stretching disc 15 drives the negative pressure ring rubber ring 16 on it, which stably extends and retracts within the negative pressure shaft barrel 11, thereby changing the air pressure within the negative pressure shaft barrel 11. Through this negative air pressure, the negative pressure of the rubber ring on the negative pressure disc 12 inside the negative pressure shaft barrel 11 is extended and retracted, thereby creating negative pressure adsorption and fixation between the negative pressure ring rubber ring 16 and the contact surface, thus adsorbing and fixing the U-shaped limiting block 2. The telescopic slider 7 inside the telescopic limiting groove 6 on the loop-shaped limiting block 2 moves telescopically, driving the concave bearing block 8 on it. The concave bearing block 8 drives the I-shaped rod 9 on it, which in turn drives the support fixing frame 1 on the other side of the concave bearing block 8. This causes the toothed support block 3 on the support fixing frame 1 to rotate along the angle axis 4 on the other toothed support block 3, thereby changing the support angle. At the same time, the expansion spring on the telescopic slider 7, in cooperation with the expansion ball, limits the telescopic limiting groove 6, which can fix the loop-shaped limiting block 2 to the wall or other surfaces. It also changes the angle between the support fixing frame 1 and the loop-shaped limiting block 2 to meet the relative requirements. The rotation of the rotating disc magnet changes the contact between the rotating disc magnet and the concave metal sheet, thereby changing the magnetism on the concave metal sheet and thus changing the adsorption or repulsion effect on the expansion ball.

[0019] In summary, when the U-shaped limiting block 2 is attached to the wall / tabletop, the negative pressure disc 12 and the contact surface form a preliminary sealing cavity, and the negative pressure shaft barrel 11 is connected to the outside through the negative pressure convex groove 10. Rotating the negative pressure disc 12 drives the negative pressure threaded tube 13 to rotate, which in turn drives the negative pressure threaded rod 14 to move axially. The negative pressure stretching disc 15 stretches from the inside to the outside along the negative pressure shaft barrel 11, and the negative pressure ring rubber ring 16 moves outward simultaneously, increasing the volume of the sealing cavity. The internal air pressure decreases to below the external atmospheric pressure, forming a negative pressure adsorption force. The negative pressure disc 12 and the rubber ring tightly adhere to the support surface, and the negative pressure ring rubber ring 16 and the... The inner wall of the negative pressure shaft barrel 11 forms a secondary seal to ensure continuous and stable negative pressure. The negative pressure stretching disc 15 achieves low-friction sliding through a linear bearing to ensure smooth adjustment. The spiral engagement between the negative pressure threaded tube 13 and the negative pressure threaded rod 14 achieves self-locking to prevent retraction. The telescopic slider 7 slides within the telescopic limiting groove 6 with a convex profile, causing the concave bearing block to shift. This shifts the support fixing frame 1 through the I-shaped rod, and the toothed support block 3 rotates around the angle axis 4 to adjust the support angle. When the telescopic slider 7 moves, the expansion spring in the expansion groove pushes the expansion ball out and engages with the pre-set positioning hole forming machine on the inner wall of the telescopic limiting groove 6. Mechanical limiting prevents angle rebound, and the multi-level positioning hole design meets the needs of various scenarios; three pairs of stretching and extruding blocks 18 are pushed outward along the horizontal telescopic extrusion groove 19 by the elastic force of the extrusion spring column, forming an elastic clamping force on the side of the tablet computer to prevent slippage. The anti-slip pad at the bottom of the support bracket 1 and the adsorption fixture form a vertical + horizontal two-way fixation to enhance overall stability; the overall operation process is as follows: the U-shaped limiting block 2 is fixed to the support surface by negative pressure adsorption to form a base point, and the angle is adjusted by the linkage mechanism of telescopic slider 7-I-shaped rod-toothed support block 3 and locked by the extension spring + extension ball, limiting the extruder. Using a spring-loaded clamping device, the adsorption fixture enhances the fixing effect through negative pressure. The negative pressure adsorption can adapt to different surfaces such as glass, wood, and tiles, meeting the needs of various scenarios such as watching movies, drawing, and writing. The design also includes a negative pressure maintenance mechanism, an air leakage prevention design, and safety redundancy. The negative pressure disc 12 rubber ring is made of high-elasticity silicone material, and the negative pressure ring rubber ring 16 is equipped with a double-lip sealing structure to prevent gas leakage. The I-shaped rod and the concave bearing block adopt an interference fit to avoid shaking, and the extension ball is made of wear-resistant ceramic material to improve the durability of the limit position. Ultimately, it achieves a comprehensive requirement of portability, adaptability, and safety.
