[0033] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0034] This utility model embodiment provides a computer all-in-one with a foldable stand, such as... Figures 1 to 5 As shown, the all-in-one computer includes a main unit 100, a base 1, and a stand 4; a touch screen 2 is mounted on the front of the main unit 100.

[0035] The bracket 4 includes a connecting plate 41, a first connecting arm 42, and a second connecting arm 43. The back of the main body 100 is mounted on the connecting plate 41. One end of the first connecting arm 42 is rotatably mounted on the connecting plate 41 so that the main body 100 can be tilted and adjusted. The other end of the first connecting arm 42 is rotatably connected to one end of the second connecting arm 43 so that the main body 100 can be adjusted in height by rotating the first connecting arm 42. The other end of the second connecting arm 43 is mounted on the base 1.

[0036] The first connecting arm 42 and the second connecting arm 43 are rotatably connected so that the lower edge of the main body 100 can be supported on the placement surface of the all-in-one computer. The first connecting arm 42 is rotatably connected to the connecting plate 41 so that the touch screen 2 can be adjusted to use the tilt angle.

[0037] This utility model discloses an all-in-one computer whose main body 100 is supported by a base 1 and a bracket 4. The bracket 4 includes a connecting plate 41, a first connecting arm 42, and a second connecting arm 43. The back of the main body 100 is mounted on the connecting plate 41. One end of the first connecting arm 42 is rotatably mounted on the connecting plate 41 to allow the main body 100 to tilt. The other end of the first connecting arm 42 is rotatably connected to one end of the second connecting arm 43, allowing the main body 100 to adjust its height by rotating the first connecting arm 42. The other end of the second connecting arm 43 is mounted on the base 1. In this way, the user can adjust the height of the touch screen 2 by rotating the first connecting arm 42, for example, lowering it to a position where it rests on a surface. At the same time, the user can adjust the tilt angle of the main body 100 by rotating the first connecting arm 42 and the connecting plate 41, thereby adjusting the tilt angle of the touch screen 2, for example, tilting the touch screen 2 backward. The user position is flexibly adjusted, allowing the user to comfortably operate the touch screen 2.

[0038] Specifically, the first connecting arm 42 has a first connecting portion 421 on both sides of the end near the second connecting arm 43, and the second connecting arm 43 has a second connecting portion 431 on the end away from the base 1. The first connecting portions 421 are rotatably mounted on both sides of the first connecting portion 421 via a rotating shaft. The arrangement of the first connecting portion 421 and the second connecting portion 431 facilitates the rotatable connection between the first connecting arm 42 and the second connecting arm 43. The rotating shaft can be a damping rotating shaft.

[0039] Furthermore, the end faces of the second connecting arms 43 on both sides of the second connecting portion 431 are configured as inclined surfaces 432, and the inclined surfaces 432 are inclined toward the base 1 in the direction from the side away from the main body 100 to the side closer to the main body 100. In this solution, the end faces of the second connecting arms 43 on both sides of the second connecting portion 431 are provided with inclined surfaces 432, and the inclined surfaces 432 are inclined toward the base 1 in the direction from the side away from the main body 100 to the side closer to the main body 100. Such inclined surfaces 432 avoid the second connecting portion 431, increase the rotation angle range of the first connecting arm 42, and make the rotation range of the first connecting arm 42 larger and more flexible, while avoiding interference between the end faces of the second connecting portion 431 and the second connecting arm 43.

[0040] Specifically, the minimum gap between the circumferential surface of the second connecting part 431 and the inclined surface 432 is 1mm to 1.5mm. The gap between the second connecting part 431 and the circumferential surface of the inclined surface 432, and the minimum gap distance of 1mm to 1.5mm, ensures that the second connecting part 431 is not prone to interference with the inclined surface 432 during rotation.

[0041] Furthermore, the second connecting arm 43 is tilted away from the main body 100 in the direction from the end near the base 1 to the end away from the base 1. The second connecting arm 43 tilting away from the main body 100 facilitates the adjustment of the tilt angle of the touch screen 2, and also improves the ability of the base 1 to maintain its center of gravity when the main body 100 is in the lowered usage state.

[0042] A rotating connecting part 44 is provided on the connecting plate 41. Third connecting parts 422 are provided on both sides of the end of the first connecting arm 42 away from the second connecting arm 43. The third connecting parts 422 are rotatably connected to the rotating connecting part 44 via a rotating shaft. The rotating connecting part 44 and the third connecting part 422 facilitate the rotatable connection between the first connecting arm 42 and the connecting plate 41. The connecting plate 41 can be mounted on the back of the main body 100 by screws or other means, and the third connecting parts 422 can be mounted on the connecting plate 41 by screws or other means; further details will not be provided here.

[0043] The main unit 100 also includes a main unit 3; a first magnetic structure 31 is provided on the front of the main unit 3, and a second magnetic structure 21 is provided on the back of the touch screen 2; the first magnetic structure 31 includes a first magnetic metal block 311 and a first magnet 312, the first magnetic metal block 311 has a mounting hole 3111, the first magnetic metal block 311 is screwed onto the front of the main unit 3 through the mounting hole 3111, and the first magnet 312 is magnetically attracted to the first magnetic metal block 311; the touch screen 2 is magnetically attracted to the front of the main unit 3 through the second magnetic structure 21 and the first magnet 312, and the touch screen 2 is electrically connected to the main unit 3.

[0044] This utility model discloses a magnetically detachable all-in-one computer. A first magnetic structure 31 is provided on the front of the main unit 3, and a second magnetic structure 21 is provided on the back of the touchscreen 2. The touchscreen 2 is installed through the magnetic attraction between the first and second magnetic structures 31, and is magnetically attached to the main unit 3. Compared to a snap-on method, the magnetic attraction method makes the touchscreen 2 easy and quick to install and remove in production, use, and maintenance scenarios. Furthermore, since it is difficult to directly drill mounting holes 3111 on the first magnet 312 for screw fixing, a first magnetic metal block 311 is provided. Mounting holes 3111 are drilled on the first magnetic metal block 311, and the first magnetic metal block 311 is screwed onto the front of the main unit 3 through the mounting holes 3111. The first magnet 312 is then attracted and fixed to the first magnetic metal block 311, thus solving the problem of difficult installation of the first magnet 312.

[0045] Specifically, at least two sets of first magnetic structures 31 are spaced apart at each edge of the front of the host 3. The second magnetic structure 21 is elongated, and at least one second magnetic structure 21 is provided at each edge of the back of the touchscreen 2. Each second magnetic structure 21 on the back of the touchscreen 2 magnetically attracts at least two sets of first magnetic structures 31 on the corresponding edge of the front of the host 3. This multi-point magnetic attraction method significantly enhances the connection stability between the touchscreen 2 and the host 3 compared to single-point magnetic attraction. Multi-point force distribution disperses pressure, preventing the touchscreen 2 from loosening or detaching due to excessive localized force. The elongated shape of the second magnetic structure 21 allows for full contact and magnetic attraction with multiple sets of first magnetic structures 31 on the host 3, further increasing the magnetic area and magnetic force, thereby improving the overall connection strength.

[0046] like Figures 5 to 11 As shown, the main unit 3 includes a main unit housing 32, and a connecting plate 41 is mounted on the back of the main unit housing 32. A mounting edge 321 is provided inside the main unit housing 32, forming a mounting cavity 322. A stud 323 is provided in the mounting cavity 322. A mounting hole 311 is formed on the first magnetic metal block 311. The first magnetic metal block 311 is mounted in the mounting cavity 322 by a screw passing through the mounting hole 3111 and screwed onto the stud 323. The mounting edge 321 inside the main unit housing 32 provides a dedicated mounting space for the first magnetic metal block 311, making its installation more stable. The stud 323 can be screwed onto the first magnetic metal block 311 to secure it.

[0047] The first magnetic metal block 311 has locking side protrusions 3112 on both sides and locking protrusions 3113 at both ends. On the mounting edge 321, the mounting cavity 322 has locking side openings 3211 on both sides. The locking side protrusions 3112 are engaged with the locking side openings 3211, and the locking protrusions 3113 are engaged with both ends of the mounting cavity 322. The first magnetic metal block 311 is engaged with the locking side openings 3211 and both ends of the mounting cavity 322 via the locking side protrusions 3112 and locking protrusions 3113, thus fixing the first magnetic metal block 311 from multiple dimensions. In addition to the connection between the screw and the stud 323, the locking structure, which engages the locking side protrusion 3112, the locking protrusion 3113, the locking side opening 3211, and the two ends of the mounting cavity 322, further restricts the movement of the metal block in the lateral and longitudinal directions, ensuring that the first magnetic metal block 311 is more securely fixed.

[0048] Specifically, the electrical connection between the touchscreen 2 and the host 3 can be achieved using conventional methods known to those skilled in the art, such as contact electrical connection terminals or pin header plugs and sockets, thereby enabling the power supply to the touchscreen 2 and the transmission of display signals, etc., which will not be described in detail here. The touchscreen 2 also includes necessary backlight modules, etc., and the host 3 also contains necessary computer circuitry such as the motherboard, display driver board, graphics card, hard drive, cooling fan, and various necessary interfaces and control switches, etc., which are conventional components known to those skilled in the art, and will not be described in detail here.

[0049] It should be understood that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Those skilled in the art can modify the technical solutions described in the above embodiments, or make equivalent substitutions for some of the technical features; and all such modifications and substitutions should fall within the protection scope of the appended claims of this utility model.
