[0045] Stands, as common structural components, serve as auxiliary structures for electronic devices, such as smartphones and tablets, to support them and provide users with a good field of vision. Traditional stand structures typically feature frames to connect electronic devices, offering both connection and protection. However, these structures are often large, solely providing support, and are difficult to integrate with other devices, limiting their application scenarios. While stand structures are usually similar in size to the electronic device for stability, they are inconvenient to install, use, and carry. Changing the stand device is necessary to achieve different heights or field of vision, further limiting their application and increasing production costs. With the increasing demand for multi-scenario and multi-functional applications, existing stand designs struggle to meet the needs of rapid application, modular combination, and cost control. Especially in applications requiring portable devices, combined use, outdoor applications, storage, and educational environments, higher demands are placed on the portability and compatibility of stands.

[0046] Tablets are typically larger than smartphones, which places higher demands on the stability and portability of magnetic back-mounted stands. However, current technologies for magnetic back-mounted stands for tablets simply increase the size of the stand to fit the tablet, limiting its cross-domain applications and making it difficult to achieve multi-functionality or quick adaptation to different needs. Furthermore, the increased size also raises manufacturing costs and timelines, further restricting large-scale deployment and widespread adoption.

[0047] To address the problems existing in the prior art, this application proposes a magnetic back-attachment bracket 100, which is particularly suitable for tablet computers 200. (See reference...) Figure 1 and Figure 2The connector 10 is provided with an adhesive part 13 for connecting to an external electronic device. The connector 10 can be placed on the back of the electronic device so that the display screen of the front of the electronic device faces the user. In use, the adhesive part 13 can be directly connected to the back of the electronic device by pasting, magnetic attraction, etc., avoiding the installation process required by traditional brackets. One end of the rotating part 20 is rotatably connected to the connector 10, and the other end is close to or far away from the connector 10 to support the electronic device. When the rotating part 20 is rotated to the same horizontal plane as the connector 10, the magnetic back-attached bracket 100 is attached to the back of the electronic device for storage without occupying space. The magnetic part 30 provided on the connector 10 can be directly magnetically attached to other external supports and devices without removing the electronic device, which is convenient for quick change of usage scenarios or storage. The setting of the magnetic part 30 increases the application scenarios of the magnetic back-attached bracket 100 without taking up too much volume.

[0048] In manufacturing, the connector 10 is formed by connecting the first connecting plate 111, the second connecting plate 112, and the third connecting plate 115. The third connecting plate 115 forms the first connecting part 11. The rotating part 20 is formed by connecting the third connecting plate and the fourth connecting plate. The first connecting plate 111, the second connecting plate 112, the third connecting plate, the fourth connecting plate, and the fifth connecting plate 113 are all fiberglass boards. They can also be epoxy boards, PC boards, or composite boards, etc. The surface of the magnetic backing bracket 100 is covered with leather. The leather is covered after the connector 10 and the rotating part 20 are connected, and the edges are sealed by hot pressing to form a composite structure of leather and fiberglass board for the magnetic backing bracket 100. The material of the leather can be semi-silicone, PU leather, microfiber leather, or eco-leather, etc. After hot pressing and edge trimming, this structure is thin and miniaturized, giving the magnetic backing bracket 100 advantages such as low production cost and easy carrying and storage. The leather also provides a good user experience.

[0049] Based on the above description, the magnetic back-attachment bracket 100 can be implemented through the following embodiments:

[0050] Example 1:

[0051] This embodiment provides a conventional method of using the support, such as... Figure 3As shown, the magnetic back-attachment bracket 100 is connected to the tablet computer via an adhesive portion 13 provided on the connector 10. The adhesive portion 13 can be one, two, or more. In this embodiment, the adhesive portion 13 may include a first adhesive portion 131 and a second adhesive portion 132. The first adhesive portion 131 and the second adhesive portion 132 are used to adhere to the back of the tablet computer 200. The first adhesive portion 131 is arranged in a ring shape on the first connecting portion 11. The area of ​​the second adhesive portion 132 is larger than that of the first adhesive portion 131 and is laid along the side length of the tablet computer 200 and also adhered to the back of the tablet computer 200, thereby improving the stability of the connection. In other embodiments, the structure or number of adhesive portions 13 is not limited.

[0052] Optionally, the adhesive part 13 is made of acrylic adhesive to strongly bond the tablet computer 200, thereby ensuring that the connector 10 is fully bonded to the tablet computer 200.

[0053] One end of the rotating part 20 is connected to the connector 10 via a hinge 40. The hinge 40 is a louvered damping hinge. The user can rotate the rotating part 20 by force to adjust the angle between the rotating part 20 and the connector 10 to the desired field of vision and then fix it. The hinge 40 allows the rotating part 20 to rotate within a range of 0 to 180°. When the angle between the rotating part 20 and the connector 10 is 0°, the two are on the same plane and fit against the tablet computer 200, thus forming a whole with the tablet computer 200. When it is not necessary to support the tablet computer 200, the angle of the rotating part 20 can be adjusted to store it with the tablet computer 200. When it is used again, no installation is required. Simply adjust the rotating part 20 to achieve support, which is convenient for use and storage.

[0054] Alternatively, the rotating part 20 and the connecting member 10 can be rotatably connected and fixed in other ways, such as by hinges, pivots, etc. (See reference). Figure 4 In this embodiment, the hinge 40 has a first leaf 41 and a second leaf 42. The first leaf 41 is sandwiched between the first connecting plate 111 and the second connecting plate 112 of the connector 10 and is fixedly connected by adhesive. The second leaf 42 is sandwiched between the third connecting plate and the fourth connecting plate of the rotating part 20 and is fixedly connected by adhesive. The first leaf 41 and the second leaf 42 are connected by a damping shaft. Multiple first and second leaf 41 are provided, and the first and second leaf 42 are arranged symmetrically to ensure the stability of the connection.

[0055] During the rotation of the rotating part 20, the connector 10 is fixedly connected to the tablet computer 200. In order to maintain the stability of the connection and the stability of the adjustment process, the first connector 11 is located in the middle of the tablet computer 200. The rotating part 20 is provided with a notch 21 to accommodate the first connector 11, and the two are structurally compatible. This matching method reduces the number of connecting parts and volume, minimizing the structure of the magnetic back-attach bracket and reducing production costs.

[0056] In terms of structural size, the cross-sectional area of ​​the magnetic back-attachment bracket 100 is smaller than that of the external electronic device. After the magnetic back-attachment bracket 100 is attached to the tablet computer 200, it can be hidden from the user. That is, the magnetic back-attachment bracket 100 is blocked by the tablet computer 200 and does not appear in the user's line of sight, providing a good visual experience. Moreover, the user can pick up and move the tablet computer 200 by holding the rotating part 20. The notch 21 provides a groove for easy holding. This method provides convenience for the user to move or hold the tablet computer.

[0057] In addition to supporting and storing the tablet computer 200, the magnetic component 30 can also be connected to an external stand, such as a retractable stand. The magnetic component 30 and the first adhesive part 131 are both located on the first connecting part 11, so that both sides of the first connecting part 11 can be used for connection, making full use of the structural space and further controlling the volume. The magnetic component 30 located on the first connecting part 11 is also easy to be attracted to the external stand, and can stably support the tablet computer 200 after being attracted. The retractable adjustable stand can provide height adjustment function, so that the tablet computer 200 has more viewing angles.

[0058] The first connecting part 11 is circular or near-circular to ensure a stable connection. The magnetic suction part 30 is provided on the first connecting part 11 so that the external bracket can be connected when the tablet computer 200 is in landscape or portrait mode without being affected by angle or direction.

[0059] The magnetic component 30 can also be magnetically attached to the magnetic device on the wireless charging module to achieve charging while supporting it. Combined with the retractable bracket, the magnetic back-attached bracket 100 realizes multiple application scenarios for support, adjustment and charging.

[0060] Optionally, the magnetic attachment 30 can be disposed between the first connecting plate 111 and the second connecting plate 112, or between the second connecting plate 112 and the third connecting plate 113, to achieve magnetic attraction with an external bracket, thereby improving expandability and multifunctionality. In this embodiment, the magnetic back-attached bracket 100 is used for temporary adsorption connection with a metal bracket. During the adsorption process, the tablet computer 200 does not need to be detached from the attachment 10 to complete the overall movement, fixation, or switching of usage scenarios of the device, improving ease of use and flexibility.

[0061] refer to Figure 5 This embodiment, through the cooperation of connector 10, rotating part 20 and magnetic component 30, provides conventional usage scenarios for magnetic component 100 to connect and store tablet computer 200, magnetic component 100 to support tablet computer 200, and magnetic component 30 to connect with external bracket. Users can choose to use it according to their needs, which greatly enriches the user's usage scenarios.

[0062] Example 2:

[0063] This embodiment provides a scenario for adsorption onto an external plane. When the first connecting plate 111, the second connecting plate 112, and the fifth connecting plate 113 are fixed with adhesive, the fifth connecting plate 113 is connected to the second connecting plate 112. The fifth connecting plate 113 is located on the side away from the tablet computer 200. The magnetic suction member 30 is located between the second connecting plate 112 and the fifth connecting plate 113 to facilitate magnetic connection to the external plane. The fifth connecting part 113 and the magnetic suction member 30 form a structure that protrudes from the second connecting plate 112. When the first connecting part is connected to other planes through the magnetic suction member 30, there is a gap between the tablet computer 200 or the second connecting plate 112 and the plane, so that when the magnetic backing bracket 100 is removed, the user can quickly take it out or separate it through the gap, which is convenient for the user to operate.

[0064] The area of ​​the fifth connecting plate 113 is smaller than that of the second connecting plate 112. After the fifth connecting plate 113 is connected to the second connecting plate 112, the thickness of the overlapping area between the fifth connecting plate 113 and the second connecting plate 112 is greater than the thickness of the non-overlapping area between the fifth connecting plate 113 and the second connecting plate 112. That is, the fifth connecting plate 113 protrudes from the second connecting plate 112 to form a difference in thickness. After the fifth connecting plate 113 is connected to the outer plane, the second connecting plate 112 is not in contact with the outer plane, and a gap is formed between the second connecting plate 112 (or the tablet computer 200) and the outer plane so that the second connecting plate 112 (or the tablet computer 200) can be removed from the outer plane.

[0065] Optionally, the magnetic attractor 30 can be a single piece or multiple magnetic cores. In this embodiment, the magnetic attractor is configured with multiple magnetic cores arranged in a ring or array to improve the stability of adsorption and save costs. Multiple grooves for placing multiple magnetic cores can be provided between the first connecting plate 112 and the fifth connecting plate 113, or the magnetic cores can be glued together to fix the magnetic cores between the first connecting plate 112 and the fifth connecting plate 113. The multiple magnetic cores are arranged on the side away from the tablet computer 200 for faster magnetic attraction.

[0066] This embodiment is particularly suitable for the following scenarios: metal flat devices such as refrigerator panels and teaching panels. After the magnetic core bracket 100 is magnetically attached to the flat device, the first connecting part 11 is magnetically connected to the flat device, and there is a gap between the rotating part 20 and the flat device. The user can quickly separate the tablet computer 200 from the flat device, or switch scenes to quickly attach the tablet computer 200 to other magnetic devices to achieve functions such as wall mounting and display. During this process, the user does not need to disassemble or install, making it convenient for the user to use. The magnetic component 30 is quickly positioned and fixed on the target bracket by magnetic force, further improving the system's portability and scene compatibility.

[0067] Example 3:

[0068] Based on the foregoing embodiments, this embodiment provides an extended use case for connecting the keyboard 50.

[0069] In the scenario of Embodiment 1, after the connector is attached to the tablet computer 200, the tablet computer 200 can be placed on the table by adjusting the rotating part 20. (Refer to...) Figure 6 and Figure 7 The connector 10 is provided with a fastening part 15, which is used to connect external components, such as protective covers, drawing tablets, touchpads, etc. In this embodiment, the fastening part 15 is used to fasten and connect with the keyboard 50, thereby forming a whole between the keyboard 50 and the magnetic back-attachment bracket 100. The rotating part 20 is used for support, which not only facilitates carrying but also allows the keyboard 50 to be used from different viewing angles. Specifically, the fastening part 15 adopts a snap-fit ​​structure, including two symmetrically arranged snap-fit ​​positions located on the left and right edges of the connector 10. Correspondingly, the keyboard 50 body is provided with a button structure for engaging the fastening part 15. By pressing to fasten and releasing, the bracket and keyboard 50 can be quickly assembled and disassembled, providing a working mode similar to that of a laptop. This structure is particularly suitable for users who need to perform text input and editing work in mobile scenarios, such as office and teaching settings.

[0070] Based on Embodiment 2, the scenario of using the magnetic back-mounted stand 100 in conjunction with the external keyboard 50 and the external stand is further described. The connector 10 is connected to the tablet computer 200, and both the rotating part 20 and the connector 10 are attached to the tablet computer 200. The magnetic part 30 is magnetically attached to the external metal device. The external keyboard 50 is connected to the tablet computer 200 via Bluetooth. By adjusting the external metal device, input can be made using the keyboard 50 in different scenarios, or remote input can be achieved, thus improving the usability of the magnetic back-mounted stand 100.

[0071] At the same time, refer to Figure 8 and Figure 9The keyboard 50 can also be folded relative to the connector 10 for storage, so that the keyboard, tablet and magnetic back support 10 can be folded into a whole, making it easy to carry and transport.

[0072] Based on Embodiment 3, the material and structure of the fastening part 15 are not limited, so it can be used in conjunction with other protective covers, drawing boards, touch panels and other devices. For example, when connected with a protective cover, the protective cover cooperates with the magnetic backing bracket 100 to place the electronic device between the protective cover and the magnetic backing bracket 100 to protect the electronic device.

[0073] Based on any of the foregoing embodiments, the support portion 22 provides horizontal support, with reference to Figure 10 This allows the tablet computer 200 to be viewed in landscape mode. One corner of the rotating part 20 is also provided with a bendable support part 22. The support part 22 has a certain area and provides support for external electronic devices when they are placed vertically, so that the tablet computer 200 can be viewed in portrait mode.

[0074] The magnetic back-attach bracket 100 has the following production process:

[0075] S1: Leather cutting

[0076] Cut the leather material according to the design drawings or template dimensions of the magnetic backing bracket 100 to prepare for subsequent processes.

[0077] S2: Sheet preparation

[0078] Fiberglass boards are selected and cut to meet structural requirements to form the first connecting plate 111, the second connecting plate 112, the third connecting plate, and the fourth connecting plate. Metal plates are selected and cut to meet structural requirements to form the fifth connecting plate 113.

[0079] S3: Apply adhesive to the pivot.

[0080] The first leaf 41 of the hinge 40 is sandwiched between the first connecting plate 111 and the second connecting plate 112 of the connector 10, and the first connecting plate 111 and the second connecting plate 112 are fixedly connected by applying glue; the second leaf 42 is sandwiched between the third connecting plate and the fourth connecting plate of the rotating part 20, and the third connecting plate and the fourth connecting plate are fixedly connected by applying glue.

[0081] S4: Magnet Assembly

[0082] The pre-prepared magnetic clasp 30 is embedded between the second connecting plate 112 and the fifth connecting plate 113.

[0083] S5: Pressure Holding

[0084] The structure formed by S3 and S4 is subjected to pressure holding.

[0085] S6: Leather Fitting

[0086] The leather cut from S1 is then bonded to the structure after being pressed in S5 to form a one-piece structure.

[0087] S7: Hot pressing

[0088] The S6 structure is formed by heating and pressurizing using a hot pressing device.

[0089] S8: Trimming

[0090] Use an edge trimming machine or manual methods to remove excess leather or rough edges.

[0091] S9: Buttoning

[0092] Fasteners 15 are inserted into preset positions on the leather for subsequent connection with the keyboard.

[0093] S10: Quality Inspection

[0094] This production method employs processes such as material cutting, gluing, hot pressing, and trimming. Compared to the traditional injection molding production method, it directly cuts the sheet material (first connecting plate 111, second connecting plate 112, third connecting plate, fourth connecting plate, and fifth connecting plate 113), making the process more flexible and avoiding the production costs and long production cycles associated with traditional molds. Producing the magnetic back-attached bracket 100 using this method reduces production costs and offers advantages such as short production cycles, high production efficiency, and suitability for mass production.
