[0019] Please see the appendix Figures 1-4 As shown, this utility model provides a multi-angle adjustable bracket for electronic devices, including a base 1 and a middle bracket 2, an upper bracket 3, and an adjusting plate 4 that rotate above the base 1, enabling free rotation in the horizontal direction. The middle bracket 2 is used to support the electronic device, and the upper bracket 3 is located on the side of the middle bracket 2. The upper bracket 3 is used to determine the mounting height of the electronic screen. The back of the adjusting plate 4 is provided with a hanging ear 5, and the adjusting plate 4 is hinged to the end of the upper bracket 3 through the hanging ear 5. It can be unfolded or folded in the vertical direction to achieve the tilt angle adjustment of the electronic device. A damping rod 6 is also provided below the hinge part between the upper bracket 3 and the adjusting plate 4.

[0020] Specifically, the base 1 rotates on the middle support 2 above the base 1, allowing the middle support 2 to rotate freely within a 360° range.

[0021] The damping rod 6 is hinged at one end to the upper bracket 3 and at the other end to the adjusting plate 4 to provide support force. The hinge position on the lug 5 is provided with a fixed shaft to fix the adjusting plate 4 to the upper bracket 3 under pressure.

[0022] Specifically, the design of the damping rod 6 and the fixed shaft can maintain the stability of the adjusted angle and prevent slow sagging due to the weight of the equipment. At the same time, the fixed shaft and the damping rod 6 form a double stabilizing structure, which effectively improves the load-bearing stability of the adjustment plate 4 at different elevation angles, ensuring that the electronic equipment maintains its angle during use and adapts to the needs of long-term viewing or operation. It also effectively reduces mechanical fatigue caused by frequent adjustments.

[0023] Please see the appendix Figure 2 As shown, the base 1 has symmetrical support legs 101 on its side.

[0024] The base 1 has elastic pads on its bottom surface to adapt to different desktop materials and reduce slippage. The symmetrical support legs 101 are designed to form an expandable support base, which enhances the overall stability of the bracket and can effectively prevent tipping, especially when adjusting the tilt angle of the tray 4.

[0025] Please see the appendix Figure 2 As shown, the middle support 2 has symmetrical slots 201. The top of the middle support 2 and the two sides of the slots 201 protrude to form bosses 202. The bosses 202 gradually decrease in size from bottom to top. The side of the middle support 2 has a cable tray 203 that communicates with the slots 201.

[0026] Specifically, a soft edge can be provided at the top of the boss 202 to prevent scratching the equipment casing. The height of the boss 202 can effectively prevent the electronic equipment from directly contacting the middle bracket 2 when it is placed, increase the space between the bottom of the equipment and the bracket, facilitate natural heat convection, and extend the service life of the electronic equipment.

[0027] More specifically, the slot 201 can be used to reduce the weight of the middle bracket 2 and provide a heat dissipation channel. At the same time, the combination of the slot 201 and the wiring slot 203 can also be used to guide the heat dissipation direction, which helps to improve the heat dissipation of electronic devices when operating under high load and avoids performance degradation due to heat accumulation.

[0028] On the other hand, the cable tray 203 can also be used for cable routing. The empty slot 201 and the cable tray 203 are set together to facilitate the concealed routing of data cables or power cables. The cables run through to the bottom of the middle bracket 2, allowing data cables or charging cables to be laid along the inside of the bracket, improving the tidiness of the desktop and meeting the needs of daily use in multiple scenarios.

[0029] Please see the appendix Figures 3-4As shown, a rotating protrusion 204 is provided at the center of the bottom of the middle bracket 2. A rotating recess 102 is provided on the base 1 corresponding to the rotating protrusion 204. The rotating protrusion 204 is adapted to be installed inside the rotating recess 102. A ball bearing 103 is also provided inside the rotating recess 102. The bottom edge of the rotating protrusion 204 is stuck on the ball bearing 103. The inner bottom groove of the rotating recess 102 does not contact the rotating protrusion 204.

[0030] Specifically, the inner side of the cavity between the rotating concave hole 102 and the rotating protrusion 204 is covered with an anti-slip silicone layer to increase rotational resistance, thereby enabling the middle bracket 2 to rotate smoothly on the base 1 and stop at any angle, avoiding the bracket from shaking due to looseness. The design of the ball bearing 103 structure effectively reduces rotational friction and improves the smoothness of adjustment. At the same time, the anti-slip silicone layer and the ball bearing 103 work together to ensure accurate positioning, taking into account both the dual needs of flexible adjustment and stable support, and adapting to the multi-angle change needs under different usage scenarios.

[0031] The cross-sections of the base 1 and the middle support 2 are set to any one of square, rectangular or trapezoidal shapes.

[0032] Specifically, when the cross-section of the base 1 and the middle support 2 is square, the four corners are rounded to fit various desktop spaces; When the cross-section of the base 1 and the middle support 2 is rectangular, the focus is on the utilization of vertical space, which is suitable for narrow desktops or equipment layouts that require horizontal extension support. When the cross-sections of the base 1 and the middle support 2 are trapezoidal, the trapezoidal cross-section design ensures stability while optimizing material distribution, reducing overall weight without affecting strength, and making it easy to carry and move. All three cross-section shapes are achieved through injection molding process, combined with surface frosting treatment to improve texture and anti-slip properties.

[0033] Example 1: like Figure 5 As shown, the adjustable bracket in this application is used in the scenario of a laptop computer. Example 2: like Figure 6 As shown, the adjustment bracket in this application is used in scenarios where the screen and keyboard are separated; Example 3: like Figure 7 As shown, the adjustment bracket in this application is used in the scenario of tablet application; The three usage scenarios described above allow for free adjustment at multiple angles, meeting the viewing needs of users in different scenarios such as office work, watching movies, or drawing. The middle bracket 2 achieves smooth rotation through the cooperation of the rotating protrusion 204 and the rotating concave hole 102 of the base 1. The ball bearing 103 and the anti-slip silicone layer work together to ensure stable stopping at any angle without loosening or shaking. The cable routing channel 203 is connected to the empty channel 201, allowing power cords or data cables to be concealed along the inside of the bracket. The cables are led out from the bottom of the middle bracket 2, keeping the desktop tidy. The heat dissipation hollow structure is located on the surface of the middle bracket 2, effectively improving air circulation efficiency and assisting in the dissipation of heat during long-term high-load operation of laptops or other electronic devices, ensuring stable output of device performance.

[0034] The working principle of this utility is as follows: This application provides a ball bearing 103 inside the rotating recess 102, allowing the bottom edge of the rotating protrusion 204 to roll on the ball bearing 103 without directly rubbing against the base 1, thus reducing friction during rotation and making the rotation smoother. At the same time, the cavity between the rotating recess 102 and the rotating protrusion 204 is covered with an anti-slip silicone layer, providing rotational resistance. The smoothness of the ball bearing 103 and the resistance of the silicone layer work together to ensure that the middle support 2 and the equipment it supports can easily rotate to any angle within a 360° range and can stop stably without shaking. Meanwhile, the adjustment tray 4 is hinged to the end of the upper bracket 3 via the hanging lug 5 on its back. The fixed shaft on the hanging lug 5 presses the two together, forming a sturdy pivot point. When the tilt angle of the electronic device is adjusted, the damping rod 6 extends and retracts accordingly. The damping force generated inside it can effectively balance the downward pressure caused by the device's gravity, thereby maintaining angle stability. This ensures that the adjusted tilt angle can be maintained for a long time, preventing the device from slowly drooping due to gravity. Furthermore, the slot 201 and protrusion 202 on the middle bracket 2 raise the bottom of the device, forming an air circulation channel that helps dissipate heat from the bottom of electronic devices, especially laptops, and prevents heat buildup. The cable routing channel 203 is connected to the slot 201, allowing data cables or power cables to pass through the inside of the bracket, and the cables can be led out from the bottom of the middle bracket 2. This design achieves a tidy desktop and meets the needs of use in multiple scenarios.

[0035] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
