Detailed Implementation

[0018] Example 1: As Figures 1-7 As shown in the figure, the portable folding bracket proposed in this embodiment includes a tray 1 and a bracket 3. The tray 1 is a rectangular plate with chamfered corners, rounded corners or beveled corners.

[0019] The bracket 3 is rotatably connected to the rear side of the tray 1. The bracket 3 has a support plate portion. For example... Figure 3 and Figure 4 As shown, when the bracket 3 is extended upwards, it supports items via the support plate. To enhance protection, an anti-slip pad 5 can be added to the support plate to prevent wear and tear on the supported laptop or other items, and to improve the anti-slip effect. At this time, the lower tray 1 can hold an external keyboard or mouse. If the user places a laptop or tablet on the support plate of the bracket 3 to watch videos, snacks or other items can be placed on the lower tray 1. Figure 6 and Figure 7 As shown, when the bracket 3 unfolds downwards, it is supported by the support plate, which supports the entire folding bracket. The user places the items on the upper tray 1 to elevate the items.

[0020] Regarding the number of brackets 3, two brackets 3 are symmetrically arranged about the tray 1, and the overall shape of bracket 3 is L-shaped. The corners of bracket 3 can be chamfered, rounded, or beveled to avoid sharp edges. For example... Figure 1 and Figure 2 As shown, when stored, the bracket 3 folds around the outer perimeter of the tray 1. Specifically, the two brackets 3 are stored on the rear and left and right sides of the tray 1, reducing the space occupied by the entire folding stand and making it easy to carry. When the entire folding stand is in the folded state, the user can also place a laptop on the tray 1 and operate it using only the laptop's touchscreen. The tray 1 serves as the laptop's placement area, and its size is large enough to accommodate a laptop.

[0021] To enable the bracket 3 to rotate to different positions, two rotating seats 2 are provided at the rear of the support plate 1. Each rotating seat 2 corresponds to a bracket 3; one bracket 3 rotates on one rotating seat 2, and the other bracket 3 rotates on the other rotating seat 2. Each rotating seat 2 has a through-hole for the bracket 3 to rotate, providing support for the rotation process. Specifically, the through-hole includes a nut on the rotating seat 2 and a bolt 4 threadedly connected to the nut. The bolt 4 passes through a through hole at the end of the bracket 3. First, the nut is installed in place. Then, the end of the bracket 3 is inserted into the rotating groove 201, aligning the through hole with the nut. Finally, the bolt 4 is passed from the rear of the rotating seat 2 forward through the through hole and threadedly connected to the nut, allowing the bracket 3 to rotate on the bolt 4 through the through hole.

[0022] The rotating base 2 has a rotating groove 201 for the end of the bracket 3 to move. Specifically, the opening of the rotating groove 201 faces opposite directions to the two rotating bases 2, that is, both face outwards. When the bracket 3 rotates upwards or downwards, when the bracket 3 is blocked by the rotating base 2, it indicates that the rotation is in place. At this time, the support plates of the two brackets 3 can support the items above the tray 1, or directly support the entire folding bracket through the support plates.

[0023] like Figure 5 As shown, the rotating groove 201 has an inwardly protruding boss at its opening. When the bracket 3 is unfolded, it slightly pushes and deforms the outer side of the rotating seat 2, then passes over the boss, and the outer side of the rotating seat 2 returns to its original position. After the bracket 3 is fully unfolded, the boss has a certain limiting ability, preventing the bracket 3 from easily reversing. However, when the user applies a little force to push the bracket 3 in the opposite direction, it can still push the bracket 3 over the boss.

[0024] This embodiment is portable and can be used in various scenarios, providing a storage area for laptops and related accessories (external keyboards, mice) for convenient computer operation. Users can unfold the bracket 3 upwards, place the laptop on it, and use the keyboard and mouse on the lower tray 1. The bracket 3 separates the laptop from the accessories below, providing ample operating space to meet the needs of frequent computer use. The application scenarios of this folding stand are not limited to those mentioned in the background art. In regular laptop use (placing the laptop on a computer desk or study desk, with the user sitting in a chair), users can also use this folding stand. The bracket 3 is unfolded upwards, the tray 1 is placed on the computer desk or study desk, an external keyboard and mouse are placed on the tray 1, and the laptop is placed on the bracket 3, raising the laptop and improving the user's viewing angle, which is beneficial to neck health. When the bracket 3 is unfolded upwards, a laptop or tablet can be placed on the support plate of the bracket 3 to raise the laptop or tablet for convenient video viewing. When the user unfolds the bracket 3 downwards, a laptop or tablet can be placed on the tray 1 to comfortably watch videos on the raised tray 1.

[0025] Example 2: Figures 1-8 As shown in this embodiment, a portable folding stand is proposed. Compared to Embodiment 1, in this embodiment, the bottom of the tray 1 is provided with a support base 9. The support base 9 includes a fabric layer with several accommodating cavities and filler material located in the accommodating cavities. The filler material can be sponge, eps (expandable polystyrene) granules, or other fillable materials. When the folding stand is placed on the lap via the support base 9, the filler material ensures comfortable placement. The fabric layer itself is made of cloth and has a certain anti-slip effect.

[0026] Several accommodating cavities are arranged in a manner where the distance from the bottom of each cavity to the tray 1 gradually decreases from back to front. In this arrangement, the rear end of the tray 1 is higher than the front end, creating an inclined distribution that facilitates user access to items (laptops, external keyboards, or mice) on the tray 1. Alternatively, the accommodating cavities can be arranged with approximately equal distances from the bottom of each cavity to the tray 1. In this case, the tray 1 is roughly horizontal, which helps to ensure stable placement of the entire folding stand and improves stability during use. A carrying handle 10 is located at the rear end of the fabric layer. When it is necessary to carry this folding stand, the tray 3 can be folded up and stored, and the entire folding stand can be lifted using the carrying handle 10 for easy transport.

[0027] Example 3: Figures 1-8 As shown, this embodiment of the portable folding bracket, compared to embodiments one and two, has a connector 6 at the outer end of the bracket 3. The connector 6 has a groove 601, and a mounting shaft 7 is provided at the groove 601. A stop 8 is rotatably mounted on the mounting shaft 7. When the stop 8 rotates backward, it can be stored in the groove 601. When the stop 8 rotates forward, it is blocked on the front side of the groove 601. To make it easier to rotate the stop 8 out of the groove 601, an operating port 602 is designed at the rear end of the groove 601, allowing the user to insert their finger into the operating port 602 and then pry the stop 8 outward.

[0028] In this embodiment, when the bracket 3 is unfolded upwards, the baffle 8 can be rotated out from the inside of the groove 601 to prevent the item placed on the support plate of the bracket 3 from slipping off.

[0029] Example 4: Figures 1-9 As shown, this embodiment of the portable folding bracket, compared to embodiments one to three, has a stop 11 at the top front end of the tray 1, which limits the placement of items on the tray 1. The stop 11 has a storage groove 111 on its rear side, and one or two pressing members 12 are rotatably mounted on the stop 11, capable of rotating into or out of the storage groove 111. The pressing member 12 includes a spiral section and a pressing strip section. The spiral section is similar to a spring structure and is fitted around the mounting post of the stop 11. The pressing strip section is connected to one end of the spiral section and can elastically deform, thereby elastically pressing against the items on the tray 1.

[0030] When the bracket 3 unfolds downwards and supports the entire folding stand, the tray 1 is positioned above, allowing the pressing piece 12 in the storage slot 111 to be rotated out and press and limit items placed on the tray 1, such as pressing on an open book. When the entire folding stand is folded, the pressing piece 12 can also be rotated out and pressed on an open book on the tray 1, thus allowing the user to read the book without manually pressing the page.

[0031] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
