[0002] Electronic devices have become indispensable tools in people's lives and work, such as laptops, tablets, and mobile phones. However, improper use of electronic devices can easily cause harm to the user's body, such as neck, shoulder, back pain, head-down syndrome, and dizziness, mainly due to improper posture during prolonged use. Therefore, adjusting the screen of electronic devices to a suitable placement and display angle using a stand can improve the user's comfort when using electronic devices.

[0003] Currently, laptop stands have a folding function, which facilitates portability and use. For example, a prior patent with authorization number CN212178435U discloses a foldable laptop stand, which includes a first base plate, a first inclined plate, a first support rod, a second base plate, a second inclined plate, a second support rod, and a connecting mechanism. One end of the first inclined plate is rotatably connected to the first base plate. One end of the first support rod is rotatably connected to the first inclined plate, and the other end can be supported on the first base plate to make the first inclined plate tilted. One end of the second inclined plate is rotatably connected to the second base plate. One end of the second support rod is rotatably connected to the second inclined plate, and the other end can be supported on the second base plate to make the second inclined plate tilted. The connecting mechanism is connected to both the first and second inclined plates.

[0004] In the existing technology, the supporting force of the connecting mechanism is distributed vertically, and the supporting force in the middle is insufficient, resulting in insufficient support stability of the bracket. Utility Model Content

[0005] The purpose of this invention is to provide a cross-folding stand, which aims to solve the problem of insufficient support stability of laptop stands in the prior art.

[0006] This utility model is implemented as follows: a cross-folding bracket includes a first support frame, a second support frame, and a cross assembly.

The second sliding shaft is slidably arranged along the second sliding rail under external force.

[0009] Furthermore, the first sliding rail and the second sliding rail are aligned, and the first sliding shaft and the second sliding shaft are aligned. When subjected to external force, the first sliding shaft and the second sliding shaft slide synchronously.

[0010] Furthermore, the cross assembly includes a limiting structure, which is assembled with the outer ends of the first lower support plate and the second lower support plate, respectively, and the limiting structure is used to limit the degree of deployment of the first lower support plate and the second lower support plate.

[0011] Furthermore, the limiting structure includes a limiting shaft and a limiting block. The limiting block is arranged in a mating configuration with the limiting shaft, and the limiting block is protruding along the radial direction of the limiting shaft. The first lower support plate has a first support plate groove, and the second lower support plate has a second support plate groove. The first support plate groove and the second support plate groove are respectively arranged in a through configuration. The limiting block simultaneously passes through the first support plate groove and the second support plate groove. The end of the first support plate groove has a first limiting groove surface. When the first limiting groove surface abuts against the limiting block, the limiting block restricts the first lower support plate from continuing to unfold. The end of the second support plate groove has a second limiting groove surface. When the second limiting groove surface abuts against the limiting block, the limiting block restricts the second lower support plate from continuing to unfold.

[0012] Furthermore, the limiting block is arranged in a fan-shaped manner and forms a fan-shaped surface, the first support plate groove and the second support plate groove each have an arc-shaped surface, and the fan-shaped surface and the arc-shaped surface are arranged in a flat abutting arrangement.

[0013] Furthermore, the first support frame includes a first main support plate, a first swing support plate, and a first diagonal support plate. The first main support plate has the first sliding rail. The first swing support plate is hinged to the first main support plate and can be unfolded or folded.

[0027] Reference Figure 1-7 The image shown is a preferred embodiment of the present invention.

[0028] A cross-folding bracket includes a first support frame 1, a second support frame 2, and a cross assembly 3. The first support frame 1 has a first sliding rail 15, and the second support frame 2 has a second sliding rail 25. The first sliding rail 15 and the second sliding rail 25 are respectively arranged extending along the length direction. The cross assembly 3 includes a first upper support module 31, a second upper support module 32, a first lower support plate 33, and a second lower support plate 34. One end of the first upper support module 31 is movably assembled with the first sliding rail 15. The other end of 31 is hinged to the first lower support plate 33, one end of the second upper support module 32 is movably assembled with the second sliding rail 25, the other end of the second upper support module 32 is hinged to the second lower support plate 34, and the first upper support module 31 and the second upper support module 32 are hinged together. The inner end of the first lower support plate 33 is assembled with the first support frame 1, the inner end of the second lower support plate 34 is assembled with the second support frame 2, and the outer end of the first lower support plate 33 is hinged to the outer end of the second lower support plate 34.

[0029] In the folded state, the cross assembly 3 retracts, causing the first support frame 1 and the second support frame 2 to move towards each other until they collide, reducing the space occupied by the bracket and facilitating its storage and carrying. When in use, the cross assembly 3 unfolds, working in conjunction with the first support frame 1 and the second support frame 2 to provide synchronous support for electronic devices. At the same time, the first upper support module 31, the second upper support module 32, the first lower support plate 33, and the second lower support plate 34 form a whole to provide synchronous support, improving the stability of the bracket and ensuring the safe placement of electronic devices.

[0030] Furthermore, with the combined action of the first upper support module 31, the second upper support module 32, the first lower support plate 33, and the second lower support plate 34, the first support frame 1 and the second support frame 2 have better extensibility, which can meet the placement of electronic devices of different specifications.

[0031] The first upper support module 31 includes a first upper support plate 311 and a first sliding shaft 312. The first sliding shaft 312 passes through or through one end of the first upper support plate 311, and the first sliding shaft 312 is movably embedded in the first sliding rail 15. The first sliding shaft 312 is slidably arranged along the first sliding rail 15 under external force.

[0032] Thus, when the bracket is unfolded or folded, the first sliding shaft 312 slides along the first sliding rail 15 under external force. The first sliding rail 15 guides and positions the first sliding shaft 312, facilitating the switching of the bracket between the folded and unfolded states.

[0033] The second upper support module 32 includes a second upper support plate 321 and a second sliding shaft 322. The second sliding shaft 322 passes through or penetrates one end of the second upper support plate 321, and the second sliding shaft 322 is movably embedded in the second sliding rail 25. The second sliding shaft 322 is slidably arranged along the second sliding rail 25 under external force.

[0034] Thus, when the bracket is unfolded or folded, the second sliding shaft 322 slides along the second sliding rail 25 under external force. The second sliding rail 25 guides and positions the second sliding shaft 322, facilitating the switching of the bracket between the folded and unfolded states.

[0035] The first sliding rail 15 and the second sliding rail 25 are aligned, and the first sliding shaft 312 and the second sliding shaft 322 are aligned. When subjected to external force, the first sliding shaft 312 and the second sliding shaft 322 slide synchronously. This helps to reduce the risk of jamming or sliding blockage and facilitates the switching of the bracket between the folded state and the unfolded state.

[0036] The cross assembly 3 includes a limiting structure 4, which is assembled with the outer ends of the first lower support plate 33 and the second lower support plate 34 respectively. The limiting structure 4 is used to limit the degree of deployment of the first lower support plate 33 and the second lower support plate 34. In this way, under the action of the limiting structure 4, the degree of deployment of the first lower support plate 33 and the second lower support plate 34 is prevented from being too large, which would affect the support strength of the first lower support plate 33 and the second lower support plate 34.

[0037] The limiting structure 4 includes a limiting shaft 41 and a limiting block 42. The limiting block 42 is arranged in a mating arrangement with the limiting shaft, and the limiting block 42 is arranged in a protruding arrangement along the radial direction of the limiting shaft 41. The first lower support plate 33 has a first support plate groove 331, and the second lower support plate 34 has a second support plate groove 341. The first support plate groove 331 and the second support plate groove 341 are respectively arranged in a through arrangement. The limiting block 42 simultaneously passes through the first support plate groove 331 and the second support plate groove 341. The end of the first support plate groove 331 has a first limiting groove surface. When the first limiting groove surface abuts against the limiting block 42, the limiting block 42 restricts the first lower support plate 33 from continuing to unfold. The end of the second support plate groove 341 has a second limiting groove surface. When the second limiting groove surface abuts against the limiting block 42, the limiting block 42 restricts the second lower support plate 34 from continuing to unfold.

[0038] In this way, the limiting block 42 prevents the first lower support plate 33 and the second lower support plate 34 from expanding too much, thus affecting their supporting strength.

[0039] The limiting block 42 is arranged in a fan-shaped manner and forms a fan-shaped surface. The first support plate groove 331 and the second support plate groove 341 each have an arc-shaped surface. The fan-shaped surface and the arc-shaped surface are arranged in a flat contact arrangement. In this way, the relative swing of the first lower support plate 33 and the second lower support plate 34 is more stable, reducing the risk of shaking.

[0040] Alternatively, the limiting structure 4 includes a limiting block 42, a first lower support plate 33 with a first plate in a first support plate groove 331, a second lower support plate 34 with a second plate in a second support plate groove 341, and the limiting block 42 between the first and second plates. When the limiting block 42 abuts against the first plate, the first lower support plate 33 cannot continue to unfold, thus limiting the unfolding of the first lower support plate 33. When the limiting block 42 abuts against the second plate, the second lower support plate 34 cannot continue to unfold, thus limiting the unfolding of the second lower support plate 34.

[0041] Electronic devices can be laptops, tablets, mobile phones, etc. Example

[0042] The first support frame 1 includes a first main support plate 11, a first swing support plate 13, and a first diagonal support plate 14. The first main support plate 11 has a first sliding rail 15. The first swing support plate 13 is hinged to the first main support plate 11 and can be unfolded or folded. The upper part of the first diagonal support plate 14 is hinged to the first main support plate 11, and the lower part of the first diagonal support plate 14 is used for assembly with the first swing support plate 13.

[0043] When stored, the first main support plate 11, the first swing support plate 13, and the first diagonal support plate 14 are folded in sequence to reduce the space occupied by the bracket. When in use, electronic devices are placed through the first main support plate 11. The lower part of the first main support plate 11 and the lower part of the first swing support plate 13 respectively abut against the desktop. The first diagonal support plate 14 forms a triangular support with the first main support plate 11 and the first swing support plate 13 to ensure sufficient support.

[0044] The first swing plate 13 has multiple first swing plate slots, which are arranged at intervals along the length direction. The first swing plate slots are used for the lower part of the first inclined support plate 14 to be embedded, so as to adjust the support angle of the first main support plate 11 and meet different user needs.

[0045] The first support frame 1 includes a first pad 12, which is stacked with the first main support plate 11. The first pad 12 is elastically arranged and has a first pad surface for contacting electronic equipment. The first pad surface is uneven or frosted.

[0046] In this way, the first pad 12 acts as an anti-slip plate, improving the stability of the electronic device. At the same time, the first pad 12 prevents the first sliding rail 15 from being exposed, effectively preventing scratches to the electronic device when the cross assembly 3 switches states.

[0047] The second support frame 2 includes a second main support plate 21, a second swing support plate 23, and a second diagonal support plate 24. The second main support plate 21 has a second sliding rail 25. The second swing support plate 23 is hinged to the second main support plate 21 and can be unfolded or folded. The upper part of the second diagonal support plate 24 is hinged to the second main support plate 21, and the lower part of the second diagonal support plate 24 is used for assembly with the second swing support plate 23.

[0048] When stored, the second main support plate 21, the second swing support plate 23, and the second diagonal support plate 24 are folded in sequence to reduce the space occupied by the bracket. When in use, electronic devices are placed through the second main support plate 21. The lower part of the second main support plate 21 and the lower part of the second swing support plate 23 respectively abut against the table. The second diagonal support plate 24 forms a triangular support with the second main support plate 21 and the second swing support plate 23 to ensure sufficient support.

[0049] The second swing plate 23 has multiple second swing plate slots, which are arranged at intervals along the length direction. The second swing plate slots are used for the lower part of the second diagonal support plate 24 to be embedded, so as to adjust the support angle of the second main support plate 21 and meet different user needs.

[0050] The second support frame 2 includes a second pad 22, which is stacked with the second main support plate 21. The second pad 22 is elastically arranged and has a second pad surface for contacting electronic equipment. The second pad surface is uneven or frosted.

[0051] In this way, the second pad 22 acts as an anti-slip material, improving the stability of the electronic equipment. At the same time, the second pad 22 prevents the second sliding rail 25 from being exposed, effectively avoiding scratches to the electronic equipment when the cross assembly 3 switches states.

[0052] Furthermore, the cooperation between the first main support plate 11 and the second main support plate 21 facilitates the placement of electronic equipment and the assembly of the cross assembly 3. Example

[0053] The first support frame 1 includes a first main support plate 11, a first base plate 16, and a first diagonal support plate 14. The first base plate 16 is arranged horizontally. The lower end of the first main support plate 11 is hinged to the first base plate 16. The first main support plate 11 and the first base plate 16 can be unfolded or folded. The upper part of the first diagonal support plate 14 is hinged to the first main support plate 11. The lower part of the first diagonal support plate 14 is used for assembly with the first base plate 16.

[0054] In this way, when in use, the first base plate 16 is placed on the table, the first main support plate 11 is supported by the first diagonal support plate 14, and the electronic device is placed through the first main support plate 11. A triangular support is formed between the first main support plate 11, the first base plate 16 and the first diagonal support plate 14 to ensure the support strength.

[0055] The first base plate 16 has multiple first bottom grooves, which are arranged at intervals along the length direction. The first bottom grooves are used for the lower part of the first diagonal brace plate 14 to be embedded, so that the support angle of the first main support plate 11 can be adjusted to meet different user needs.

[0056] The first support frame 1 includes a first pad 12, which is stacked with the first main support plate 11. The first pad 12 is elastically arranged and has a first pad surface for contacting electronic equipment. The first pad surface is uneven or frosted.

[0057] In this way, the first pad 12 acts as an anti-slip plate, improving the stability of the electronic device. At the same time, the first pad 12 prevents the first sliding rail 15 from being exposed, effectively preventing scratches to the electronic device when the cross assembly 3 switches states.

[0058] The second support frame 2 includes a second main support plate 21, a second base plate 26, and a second diagonal support plate 24. The second base plate 26 is arranged horizontally.

The electronic device is placed through the second main support plate 21, and a triangular support is formed between the second main support plate 21, the second base plate 26 and the second diagonal support plate 24 to ensure the support strength.

[0060] The second base plate 26 has multiple second bottom grooves, which are arranged at intervals along the length direction. The second bottom grooves are used for the lower part of the second diagonal brace 24 to be embedded, so that the support angle of the second main support plate 21 can be adjusted to meet different user needs.

[0061] The second support frame 2 includes a second pad 22, which is stacked with the second main support plate 21. The second pad 22 is elastically arranged and has a second pad surface for contacting electronic equipment. The second pad surface is uneven or frosted.
