[0007] The magnetic surface of the sub-support is used for magnetic connection of the sub-support; a sub-support support portion is provided on each side of the magnetic surface of the sub-support in the width direction. The sub-support support portion is used to be separable and limited to cooperate with the sub-support to provide support force for the sub-support in the length direction around the magnetic surface of the sub-support.

[0008] In one embodiment, the main support includes two brackets arranged side by side and a telescopic frame disposed between the two supports;

[0009] The bracket includes a base plate, a support plate, and a support arm disposed between the base plate and the support plate; the base plate and the support plate extend into a long strip shape.

[0010] One end of the base plate is hinged to one end of the support plate, and the base plate is provided with a steering wheel mounting part at the hinge end for mounting the computer bracket on the steering wheel;

[0011] One end of the support arm is hinged to one of the base plate and the support plate, and the other end is inserted into the other of the base plate and the support plate.

[0012] The two support plates are connected by the telescopic frame. The support plate has a support surface for supporting the computer. The magnetic interface of the sub-support is located on the surface of the support plate that avoids the support surface. The length direction of the magnetic interface of the sub-support is consistent with the length direction of the support plate.

[0013] In one embodiment, the support plate has a mounting back surface disposed opposite to the support surface;

[0014] The magnetic interface of the sub-bracket is located on the back of the mounting plate; or, the magnetic interface of the sub-bracket is located at the connection between the back of the mounting plate and the side of the support plate.

[0015] In one embodiment, each of the two support plates is provided with at least one of the secondary bracket magnetic interfaces.

[0016] In one embodiment, the device further includes a secondary bracket for supporting the mobile terminal. The secondary bracket is provided with a magnetic docking portion adapted to the magnetic interface of the secondary bracket. The magnetic docking portion has a magnetic mating surface and a supporting mating portion. The magnetic mating surface magnetically engages with the magnetic surface of the secondary bracket, and the supporting mating portion and the supporting portion of the secondary bracket are mutually limited in the width direction and / or magnetic direction of the magnetic mating surface.

[0017] In one embodiment, the supporting mating part includes a first flange and a second flange disposed on both sides of the magnetic attraction mating surface in the width direction. The first flange protrudes along the magnetic attraction direction, and the second flange protrudes along the width direction of the magnetic attraction mating surface.

[0018] The magnetic interface of the sub-support includes a first limiting groove and a second limiting groove to form two sub-support support portions. The first flange is adapted to be embedded in the first limiting groove. The second limiting groove is located on the periphery of the main support. The second flange is adapted to be embedded in the second limiting groove along the width direction of the magnetic mating surface.

[0019] In one embodiment, the magnetic interface of the sub-support includes a magnetic member and a magnetic groove formed on the support; the bottom wall of the magnetic groove is provided with a mounting platform, the magnetic member is fixed to the mounting platform, and the magnetic mating surface is provided on the magnetic member; the magnetic member and the groove wall of the magnetic groove enclose each other to form the first limiting groove and the second limiting groove.

[0020] In one embodiment, the second limiting groove includes a bottom wall formed on the magnetic attractor, a top wall and a side wall that are located in the magnetic attractor groove and have an arc transition, and the distance between the top wall of the second limiting groove and the second flange is gradually increased away from the first flange.

[0021] In one embodiment, the length of the magnetic attraction interface of the sub-support is greater than the length of the magnetic attraction mating surface, so that the sub-support can magnetically slide along the length direction of the magnetic attraction interface.

[0022] In one embodiment, the sub-support includes a first plate and a second plate that are mutually damped and hinged together. The first plate is provided with the magnetic attraction docking part, and the second plate is provided with a mobile terminal magnetic attraction part.

[0023] In this utility model computer stand, a long, strip-shaped magnetic interface for a secondary stand is provided on the main stand. The secondary stand can support mobile terminals such as mobile phones, tablets, and extended screens, allowing the computer stand to simultaneously support laptops and mobile devices, meeting the needs of multi-screen use. The magnetic connection between the secondary stand and the main stand is simple and facilitates disassembly. Furthermore, the strip-shaped magnetic interface for the secondary stand meets the magnetic requirements while reducing the area occupied by the magnetic interface, ensuring the overall consistency of the main stand's appearance.

[0024] The sub-stand magnetic interface features a magnetic surface and a support portion. The magnetic surface allows for magnetic connection of the sub-stand, while the support portion engages with the sub-stand to provide support along its length. This design limits the sub-stand's torsional deviation from the magnetic interface and allows it to withstand greater lateral tension. This results in greater load-bearing capacity when suspending heavy tablets or extended screens, preventing the sub-stand from easily detaching from the magnetic surface and thus improving the connection stability between the sub-stand and the main stand, thereby enhancing the overall performance of the computer stand.

[0033] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0036] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text is to include three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0037] This utility model proposes a computer stand, aiming to solve the technical problem of how to improve the performance of computer stands.

[0038] In this embodiment of the utility model, as shown in Figures 1 to 5, the computer stand includes: a main stand 100 for supporting a computer; a long strip-shaped magnetic interface 10 for a secondary stand; the magnetic interface 10 for a secondary stand having a magnetic surface 11 extending along its length and a support portion 12; the magnetic surface 11 for magnetic connection of a secondary stand 200; and a support portion 12 for a secondary stand on each side of the magnetic surface 11 in the width direction, the support portion 12 for separable and limiting engagement with the secondary stand 200 to provide support for the secondary stand 200 in the length direction around the magnetic surface 11.

[0039] In this embodiment, the specific shape of the main support 100 is not limited, as long as it can support a laptop computer. The magnetic interface 10 of the secondary support is used for the detachable magnetic connection of the secondary support 200, so that the secondary support 200 can be installed on or removed from the main support 100 according to the user's actual needs. The secondary support 200 is used to support mobile terminals such as mobile phones, tablets, and extended screens. For ease of explanation, the mobile terminal is described below as a mobile phone as an example. After the user installs the secondary support 200 on the magnetic interface 10 of the secondary support and places the mobile phone on the secondary support 200, the laptop computer and the mobile phone can be set up in front of the user at the same time, so that the user can realize dual-screen operation of the computer and the mobile phone.

[0040] The sub-support 200 can be magnetically attached to the magnetic surface 11 of the sub-support. The sub-support support 12 can support and limit the sub-support 200 to prevent it from detaching directly from the magnetic interface 10 of the sub-support when under force, either along the magnetic direction or along the width direction of the magnetic surface 11. This improves the stability of the fit between the sub-support 200 and the magnetic interface 10, prevents the sub-support 200 from easily falling off the main support 100, and improves the use effect of the computer stand and enhances the user experience.

[0041] In the technical solution of this utility model computer stand, a long strip-shaped magnetic interface 10 for the secondary stand 200 is provided on the main stand 100. The secondary stand 200 can support mobile terminals such as mobile phones, tablets, and extended screens, enabling the computer stand to simultaneously support laptops and mobile terminals such as mobile phones, meeting the needs of multi-screen use. The secondary stand 200 is magnetically connected to the main stand 100, and the connection structure is simple, making assembly and disassembly more convenient. Furthermore, the strip-shaped magnetic interface 10 for the secondary stand 200 meets the magnetic attraction requirements while reducing the area occupied by the magnetic interface 10, ensuring the overall consistency of the appearance of the main stand 100.

[0042] The magnetic interface 10 of the secondary bracket is provided with a magnetic surface 11 and a support part 12. The magnetic surface 11 allows the secondary bracket 200 to be magnetically connected. The support part 12 is matched with the secondary bracket 200, so that the support part 12 can provide support for the secondary bracket 200 in the direction around the length of the secondary bracket 200. On the one hand, it restricts the secondary bracket 200 from twisting and deviating from the magnetic interface 10. On the other hand, the support part 12 can bear a large lateral pulling force, so that the magnetic interface 10 of the secondary bracket has a greater load-bearing capacity when suspending heavy tablets and extended screens. It can prevent the secondary bracket 200 from easily detaching from the magnetic surface 11, thereby preventing the secondary bracket 200 from easily falling off the main bracket 100. In this way, the connection stability between the secondary bracket 200 and the main bracket 100 can be improved, thus improving the use effect of the computer bracket.

[0043] Specifically, as shown in Figures 1 and 2, the main support 100 includes two brackets 20 arranged side by side and a telescopic frame 30 disposed between the two brackets 20; each bracket 20 includes a base plate 21, a support plate 22, and a support arm 23 disposed between the base plate 21 and the support plate 22; the base plate 21 and the support plate 22 extend into a long strip shape; one end of the base plate 21 is hinged to one end of the support plate 22, and the base plate 21 is provided with a steering wheel mounting part 24 at the hinged end for mounting the computer bracket. On the steering wheel; one end of the support arm 23 is hinged to one of the base plate 21 and the support plate 22, and the other end is inserted into the other of the base plate 21 and the support plate 22; the two support plates 22 are connected by the telescopic frame 30, the support plate 22 has a support surface 221 for supporting the computer, the sub-bracket magnetic interface 10 is provided on the surface of the support plate 22 that avoids the support surface 221, and the length direction of the sub-bracket magnetic interface 10 is consistent with the length direction of the support plate 22.

[0044] In this embodiment, the computer holder includes a steering wheel mounting portion 24, allowing it to be mounted on the steering wheel to meet the user's need for computer use in the vehicle. When the computer holder is mounted on the steering wheel, the base plate 21 rests against the steering wheel, and the support plate 22 is located on the side of the base plate 21 facing away from the steering wheel. The support plate 22 opens at an angle relative to the base plate 21, and this opening angle is adjustable so that the support angle of the computer holder for the laptop can adapt to different angle requirements of the user. After the opening angle of the support plate 22 is adjusted to a preset angle, the angle between the support plate 22 and the base plate 21 can be maintained at that preset angle by inserting the support arm 23 into the base plate 21. The support surface 221 of the support plate 22 is located on the side of the support plate 22 facing away from the base plate 21. Since the support surface 221 is for placing the computer, the magnetic interface 10 of the sub-stand should be set away from the support surface 221 to avoid the computer and the sub-stand 200 obstructing each other. The telescopic bracket 30 is telescopic in the arrangement direction of the two brackets 20, so that the distance between the two brackets 20 can be adjusted, thereby allowing the computer stand to adapt to laptops of different lengths and sizes, improving ease of use.

[0045] The main support frame of this type is foldable, making it more convenient to carry and store. Because the support plate 22 of this type of main support frame is long and narrow, the length direction of the magnetic interface 10 of the secondary support frame is consistent with the length direction of the support plate 22. This makes full use of the length of the support plate 22 and eliminates the need for additional structures to install the magnetic interface 10 of the secondary support frame, thus simplifying the overall structure of the computer stand.

[0046] In practical applications, as shown in Figure 2, the support plate 22 has a mounting back surface 222 opposite to the support surface 221; the sub-bracket magnetic interface 10 is located on the mounting back surface 222; or, the sub-bracket magnetic interface 10 is located at the connection between the mounting back surface 222 and the side of the support plate 22. Thus, even if a laptop is already placed on the support surface 221, the user can install the sub-bracket 200 on the back of the support plate 22 without first picking up the laptop, improving user convenience. Furthermore, placing the sub-bracket magnetic interface 10 on the mounting back surface 222 of the support plate 22 or at the connection between the mounting back surface 222 and the side of the support plate 22 can conceal the sub-bracket magnetic interface 10, making the overall appearance of the computer stand cleaner.

[0047] For example, as shown in Figure 2, both support plates 22 are provided with at least one of the sub-support magnetic interfaces 10. When the computer stand is in use, the two support plates 22 are arranged left and right relative to the user. Both support plates 22 are provided with sub-support magnetic interfaces 10, accommodating both left-handed and right-handed users. Users can choose to install the sub-support 200 on the sub-support magnetic interface 10 of the left support plate 22 or the sub-support magnetic interface 10 of the right support plate 22 according to their actual needs. Of course, for users who need to use two mobile phones, sub-supports 200 can also be installed on the sub-support magnetic interfaces 10 of both support plates 22 to support two mobile phones respectively.

[0048] For example, as shown in Figure 3, the computer stand also includes a secondary stand 200 for supporting a mobile terminal. The secondary stand 200 is provided with a magnetic docking part 40 adapted to the magnetic interface 10 of the secondary stand. The magnetic docking part 40 has a magnetic mating surface 41 and a supporting mating part 42. The magnetic mating surface 41 is magnetically mated with the magnetic surface 11 of the secondary stand, and the supporting mating part 42 is limited to the supporting part 12 of the secondary stand in the width direction and / or magnetic direction of the magnetic mating surface 41.

[0049] In this embodiment, the magnetic attraction mating surface 41 and the magnetic attraction surface 11 of the sub-support magnetically engage, enabling a fixed connection between the sub-support 200 and the main support 100. The supporting mating part 42 engages with the sub-support supporting part 12, thus preventing the sub-support 200 from directly detaching from the sub-support magnetic attraction surface 11 along the width direction and / or magnetic attraction direction of the magnetic attraction mating surface 41 when the force acting on the sub-support 200 along the width direction and / or magnetic attraction direction is greater than the magnetic attraction force. This serves as a limiting effect on the sub-support 200, improving the installation stability of the sub-support 200 and the main support 100.

[0050] Meanwhile, the secondary bracket 200 and the main bracket 100 are magnetically engaged only through the magnetic mating surface 41 and the magnetic mating surface 11 of the secondary bracket. The secondary bracket 200 and the secondary bracket support part 12 can be separated and limited by the supporting mating part 42, making the disassembly and reassembly of the secondary bracket 200 and the main bracket 100 more convenient and quick. In actual use, the secondary bracket 200 can also be detached from the main bracket 100 and attached to the back of the rearview mirror to create an extended screen, enabling dual-screen office functionality. The secondary bracket 200 can also be attached to the car dashboard or the back of the central control screen, achieving multiple uses for the secondary bracket 200 and solving the problem of where to store it.

[0051] Specifically, as shown in Figures 4 and 5, the magnetic attraction docking part 40 also has a first flange 43 and a second flange 44 disposed on both sides of the magnetic attraction mating surface 41 in the width direction. The first flange 43 protrudes along the magnetic attraction direction, and the second flange 44 protrudes along the width direction of the magnetic attraction mating surface 41. The auxiliary bracket magnetic attraction interface 10 includes a first limiting groove 13 and a second limiting groove 14 to form two limiting support parts 12. The first flange 43 is adapted to be embedded in the first limiting groove 13. The second limiting groove 14 is disposed on the periphery of the main bracket 100, and the second flange 44 is adapted to be embedded in the second limiting groove 14 along the width direction of the magnetic attraction mating surface 41.

[0052] In this embodiment, the first limiting groove 13 and the second limiting groove 14 both extend along the length direction of the magnetic attraction interface 10 of the sub-support, and the first flange 43 and the second flange 44 both extend along the length direction of the magnetic attraction interface 10 of the sub-support, thereby increasing the mating area between the first flange 43 and the first limiting groove 13 to improve mating stability; and increasing the mating area between the second flange 44 and the second limiting groove 14 to improve mating stability.

[0053] The first flange 43 engages with the first limiting groove 13 to restrict the movement of the sub-support 200 along the width direction (i.e., the left-right direction) of the magnetic mating surface 41, thereby preventing the sub-support 200 from detaching from the main support 100 in the left-right direction. The second flange 44 engages with the second limiting groove 14 to restrict the movement of the sub-support 200 along the magnetic direction (i.e., the front-back direction), thereby preventing the sub-support 200 from detaching from the main support 100 in the rearward direction.

[0054] It should be noted that when it is necessary to detach the sub-support 200 from the sub-support magnetic interface 10, the sub-support 200 can be rotated backward around the first flange 43 as the axis, so that the second flange 44 can first disengage from the second limiting groove 14 during the rotation of the sub-support 200. After the second flange 44 disengages from the second limiting groove 14, the first flange 43 can naturally disengage from the first limiting groove 13, thereby realizing the disassembly of the sub-support 200.

[0055] For example, as shown in FIG6, the magnetic interface 10 of the sub-support includes a magnetic member 15 and a magnetic groove 16 formed on the support 20; the bottom wall of the magnetic groove 16 is provided with a mounting platform 161, the magnetic member 15 is fixed to the mounting platform 161, and the magnetic mating surface 41 is provided on the magnetic member 15; the magnetic member 15 and the groove wall of the magnetic groove 16 enclose each other to form the first limiting groove 13 and the second limiting groove 14.

[0056] In this way, the specific formation of the first limiting groove 13 and the second limiting groove 14 can be simplified, and the effective utilization rate of the magnetic suction component 15 can be improved. This allows the magnetic suction component 15 to not only attract the sub-support 200, but also to limit the sub-support 200, thereby making the cooperation between the sub-support 200 and the magnetic suction component 15 more compact.

[0057] Specifically, as shown in Figure 5, the second limiting groove 14 includes a bottom wall formed on the magnetic suction member 15, a top wall and a side wall that are located within the magnetic suction groove 16 and have an arc-shaped transition. The distance between the top wall of the second limiting groove 14 and the second flange 44 gradually increases away from the first flange 43. This allows the second flange 44 and the second limiting groove 14 to more easily engage during the engagement of the sub-support 200 with the sub-support magnetic suction interface 10, improving the ease of installation of the sub-support 200 at the sub-support magnetic suction interface 10. It also makes it easier to detach the sub-support 200 from the sub-support magnetic suction interface 10.

[0058] For example, as shown in Figure 2, the length of the magnetic interface 10 is greater than the length of the magnetic mating surface 41, so that the sub-stand 200 can magnetically slide along the length direction of the magnetic interface 10. This allows the height of the sub-stand 200 relative to the main stand 100 to be adjustable, thereby allowing the height of the mobile phone placed on the sub-stand 200 relative to the computer placed on the main stand 100 to be adjusted. During the adjustment of the sub-stand 200's position, the sub-stand support 12 can guide the sub-stand 200 to prevent misalignment.

[0059] Specifically, as shown in Figure 3, the sub-support 200 includes a first plate and a second plate that are mutually damped and hinged. The first plate is provided with the magnetic docking part 40, and the second plate is provided with a mobile terminal magnetic attachment part 50. The sub-support 200 can be connected to the sub-support magnetic interface 10 through the magnetic docking part 40, and the mobile terminal magnetic attachment part 50 can be used to magnetically fix a mobile phone, simplifying the way the mobile phone is fixed and supported. The first plate and the second plate are damped and hinged, so the unfolding angle of the second plate relative to the first plate is adjustable. That is, the angle of the mobile phone placed on the mobile terminal magnetic attachment part 50 relative to the support plate 22 is adjustable, so the user can adjust the mobile terminal magnetic attachment part 50 to a preset position according to their own habits, thereby further improving the ease of use of the sub-support 200. In addition, when the sub-support 200 is not needed, it can be folded to reduce the space occupied by the sub-support 200 and facilitate its storage.

[0060] The above description is only an optional embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
