Typically, the wireless module is mounted on the outer casing of the display module. Therefore, during the manufacturing stage, a notch needs to be machined on the back casing to fit the shape and size of the wireless module, facilitating its insertion into the casing. However, repeated installation and removal of the wireless module can damage it, affecting the stability of its application. Summary of the Invention

[0005] A connection assembly includes a magnetic element and an elastic element, both of which are located within the accommodating cavity. The elastic element is located between the magnetic element and the outer shell. The magnetic element is used to attract and engage with an external device through the inner shell.

[0006] A stress-relieving component is disposed on the outer casing and is capable of displacement relative to the outer casing; wherein,

[0007] When the magnetic attractor is attracted to the external device, an external force is applied to the force relief member. The force relief member moves toward the magnetic attractor and is at least partially inserted between the magnetic attractor and the inner housing. The magnetic attractor moves away from the inner housing and compresses the elastic member to increase the distance between the magnetic attractor and the inner housing.

[0008] In one embodiment, the outer casing has a receiving groove communicating with the receiving cavity, the receiving groove being used to receive the stress-relieving member, and the stress-relieving member extending at least partially out of the receiving groove.

[0009] In one embodiment, the outer casing includes a main body and a bent portion, and the receiving groove is located on the bent portion;

[0010] The stress-relieving component includes a connecting part and a pressing part. One end of the connecting part is connected to the bending part, and the other end of the connecting part is connected to the pressing part. At least a portion of the pressing part extends out of the receiving groove.

[0011] In one embodiment, the distance between the center point of the connecting portion and the center point of the pressing portion is a first distance, and the distance between the force-relieving member and the outer shell is a second distance, wherein the first distance is greater than the second distance.

[0012] In one embodiment, the elastic element is configured as foam, and a first adhesive layer and a second adhesive layer are respectively provided on opposite sides of the foam. The first adhesive layer is bonded to the outer shell, and the second adhesive layer is bonded to the magnetic element.

[0013] In one embodiment, the wireless module further includes a wireless circuit board located within the accommodating cavity, and the projection of the wireless circuit board on the inner housing does not overlap with the projection of the magnetic member on the inner housing.

[0014] In one embodiment, a wireless connector is provided on the side of the wireless circuit board near the inner housing, and a clearance portion is provided on the inner housing.

[0018] This application also provides an electronic device including the display module mentioned in any of the above embodiments.

[0019] The technical solutions provided by the embodiments of this application may include the following beneficial effects:

[0020] As described in the above embodiments, the wireless module of this application includes a housing assembly, a connecting assembly, and a force-relieving component. The housing assembly includes an outer shell, an inner shell, and a receiving cavity formed between the outer shell and the inner shell. The connecting assembly includes a magnetic attractor and an elastic member located within the receiving cavity. The elastic member is located between the magnetic attractor and the outer shell. The magnetic attractor is used to attract an external device through the inner shell. The force-relieving component is disposed on the outer shell and is capable of displacement relative to the outer shell. When the magnetic attractor attracts an external device, an external force is applied to the force-relieving component. The force-relieving component moves towards the magnetic attractor, and at least partially inserts between the magnetic attractor and the inner shell. The magnetic attractor moves away from the inner shell and compresses the elastic member to increase the distance between the magnetic attractor and the inner shell. By providing a force-relieving component, this application increases the distance between the magnetic attractor and the inner shell, thereby reducing the magnetic attraction between the magnetic attractor and the external device, facilitating the disassembly of the wireless module, reducing damage to the wireless module during disassembly, and improving the stability of the wireless module.

[0037] Wi-Fi, often referred to as "mobile hotspot," is a trademark of the Wi-Fi Alliance manufacturers used for product branding. It's a wireless local area network technology based on the IEEE 802.11 standard. Wi-Fi modules can generally be installed on products using methods such as direct soldering, socket connection, or plug-in connection.

[0038] However, as mentioned in the background section, with the popularization of networks, different WIFI solutions have also become more widespread. WIFI modules typically need to be installed in a detachable manner on products to ensure compatibility with different types of WIFI modules and meet diverse needs. However, during the repeated installation and removal of WIFI modules, there is a risk of damage caused by forceful disassembly, thus affecting the stability of the WIFI module.

[0039] Based on this, this application discloses an electronic device. It can be any commercially available human-computer interaction product, such as, but not limited to, tablets, laptops, and touchscreen all-in-ones. The electronic device includes an information input module, a control module, a display module, and a housing assembly.

[0040] This application uses an all-in-one conference machine as an example for illustration. It is understood that an all-in-one conference machine integrates advanced electronic components such as a touchscreen, motherboard, memory, hard drive, and graphics card, and its working principle is no different from that of a traditional PC. It is primarily used in conference scenarios through its large screen. When the electronic device is an all-in-one conference machine, the information input module corresponds to the mouse and keyboard. The control module corresponds to the CPU (central processing unit). The display module corresponds to the display screen assembly; it is understood that the display screen assembly mainly includes components such as a glass screen, LCD screen, and backlighting.

[0041] Reference Figure 1 The housing assembly of the conference all-in-one machine includes a front shell 50, a large back shell 51, a small back shell 52, and a frame 53. The front shell 50 and the large back shell 51 are arranged along the thickness direction of the product, and the small back shell 52 overlaps the front shell 50 and the large back shell 51 and is located below the large back shell 51. The frame 53 is connected to the outer periphery of the front shell 50, the large back shell 51, and the small back shell 52. This forms a housing assembly 1 that is hollow inside and closed outside, and the control module, display module, etc. are respectively installed in the hollow cavity of the housing assembly.

[0042] In this solution, the display module includes a wireless module, which comprises a housing assembly 1, a connecting assembly 2, and a stress-relieving component 3. It is worth noting that the housing assembly here refers to the housing assembly of the wireless module, which is different from the housing assembly of the aforementioned all-in-one conference machine.

[0043] Specifically, refer to Figure 1 , Figure 2 and Figure 3 The housing assembly 1 includes an outer shell 10, an inner shell 11, and a receiving cavity formed between the outer shell 10 and the inner shell 11. The connecting assembly 2 includes a magnetic attractor 20 and an elastic member 21, both located within the receiving cavity. The elastic member 21 is located between the magnetic attractor 20 and the outer shell 10. The magnetic attractor 20 is used to attract external equipment via the inner shell 11. A force-relieving member 3 is disposed on the outer shell 10 and is capable of displacement relative to the outer shell 10. Figure 2 It can be understood that the external device here can be understood as the small back shell 52 of the conference all-in-one machine mentioned above. The magnetic attachment 20 attracts the external device through the inner shell 11, which means that the inner shell 11 of the wireless module and the small back shell 52 of the conference all-in-one machine are attached to the frame 53 by the magnetic attachment 20.

[0044] Understandably, the magnetic force formula is F = (2 × μ0 × g)(B × A) * μ1. Here, F represents the magnetic attraction force, B represents the magnetic field strength, A represents the surface area of ​​the magnet, μ0 represents the permeability in vacuum (approximately 4π × 10⁻⁷ N / A²), μ1 represents the safety factor (generally between 1.3 and 1.8), and g represents the gap between the magnet and the object. That is, the greater the distance between the magnetic chuck 20 and the small rear shell 52 (or the inner shell 11), the smaller the attraction force between the magnetic chuck 20 and the small rear shell 52.

[0045] Therefore, this application configures a force-relieving component 3 on the wireless module. During the disassembly process of the wireless module and the conference all-in-one machine, an external force is applied to the force-relieving component 3. The applied external force inserts at least part of the force-relieving component 3 between the magnetic suction component 20 and the inner housing 11. The magnetic suction component 20 moves away from the inner housing 11 and compresses the elastic component 21, thereby increasing the distance between the magnetic suction component 20 and the inner housing 11. By increasing the distance between the magnetic suction component 20 and the inner housing 11, it can also be understood as increasing the distance between the magnetic suction component 20 and the small back cover 52, thereby reducing the magnetic attraction between the magnetic suction component 20 and the small back cover 52. This facilitates the removal of the wireless module from the small back cover 52 of the conference all-in-one machine, reduces the risk of damage to the wireless module during disassembly, and improves the stability of the wireless module itself.

[0046] In some embodiments, the inner housing 11 is made of plastic. This arrangement can effectively control the magnetic attraction between the magnetic component 20 and the small rear housing 52, avoiding difficulties in disassembly due to excessive attraction during the disassembly of the wireless module, thereby preventing damage to the wireless module.

[0047] Furthermore, the thickness of the inner housing 11 must not exceed 2mm. Limiting the thickness of the inner housing 11 ensures that the magnetic attraction force remains within a reasonable range, preventing insufficient magnetic attraction between the wireless module and the small rear housing 52 due to excessive thickness, thereby ensuring the stability of the connection between the wireless module and the small rear housing 52. Secondly, reducing the thickness of the inner housing 11 can improve the portability and aesthetics of the conference all-in-one machine while ensuring sufficient structural strength.

[0048] In some implementations, reference continues. Figure 3 The outer casing 10 has a receiving groove 101 communicating with the receiving cavity. The receiving groove 101 is used to receive the stress-relieving component 3, and the stress-relieving component 3 extends at least partially out of the receiving groove 101. It should be noted that any structure capable of accommodating the stress-relieving component 3 and allowing the stress-relieving component 3 to move can be understood as the receiving groove 101. For example, the receiving groove 101 can also be a through hole structure. No limitation is made here.

[0049] In one embodiment, one receiving slot 101 is used to accommodate one stress-relieving component 3, that is, the number of receiving slots 101 is the same as the number of stress-relieving components 3. Preferably, two receiving slots 101 are provided on the outer casing 10, and each receiving slot 101 accommodates one stress-relieving component 3.

[0050] In some implementations, refer to Figure 3 and Figure 4 The outer shell 10 includes a main body 102 and a bent portion 103, with a receiving groove 101 located on the bent portion 103.

[0051] Both the main body 102 and the inner shell 11 can be configured as flat plates, while the bent portion 103 is configured as a flat plate at a certain angle to the main body 102, and the main body 102 and the inner shell 11 are connected by the bent portion 103 to form the aforementioned accommodating cavity. Preferably, the angle between the bent portion and the main body is 90°.

[0052] Specifically, placing the receiving slot 101 on the bending portion 103 can effectively reduce the size of the wireless module, reduce its space occupation, and make its application more flexible.

[0053] In some implementations, refer to Figure 5 The unloading component 3 includes a connecting part 30 and a pressing part 31. One end of the connecting part 30 is connected to the bending part 103, and the other end of the connecting part 30 is connected to the pressing part 31. At least a portion of the pressing part 31 extends out of the receiving groove 101.

[0054] Specifically, the connecting part 30 and the pressing part 31 are integrally formed and have a certain degree of elasticity. This arrangement can save the production cost of the wireless module and also meet the mobility required by the unloading part 3, so as to ensure that the pressing part 31 is displaced after being subjected to external force, so as to insert between the magnetic absorbing part 20 and the inner shell 11 to unload the force (reduce the attraction between the magnetic absorbing part 20 and the small rear shell 52).

[0055] Furthermore, the shapes of the connecting part 30 and the pressing part 31 are not limited. The connecting part 30 only needs to satisfy the connection function between the bending part 103 and the pressing part 31. The shape of the pressing part 31 only needs to be able to withstand the applied external force and respond to the external force.

[0056] In one embodiment, continue to refer to Figure 5 The pressing part 31 includes a pressing end 310 for receiving external force and a force-relieving end 311 for insertion between the magnetic member 20 and the inner housing 11. Exemplarily, the pressing end 310 is configured in an arc shape to allow the user to apply external force, improving the user experience. Exemplarily, the force-relieving end 311 gradually decreases in thickness from its middle section in the direction close to the magnetic member 20, so that the force-relieving end 311 can be inserted into the gap between the magnetic member 20 and the inner housing 11.

[0057] In one embodiment, the distance between the center point of the connecting portion 30 and the center point of the pressing portion 31 is a first distance, and the distance between the unloading member 3 and the outer casing 10 is a second distance, with the first distance being greater than the second distance. This arrangement ensures the connection strength between the pressing portion 31 and the connecting portion 30 when they are displaced relative to each other, preventing breakage and thus improving the durability of the unloading member 3.

[0058] In one embodiment, the connecting portion 30 and the bending portion 103 can be detachably or fixedly connected. Exemplarily, the connecting portion 30 and the bending portion are connected by a screw thread. Exemplarily, the connecting portion 30 and the bending portion 103 are connected by a heat-fusion process. The connection method is not limited here and can be selected according to actual needs.

[0059] In some embodiments, the elastic element 21 is configured as foam, with a first adhesive layer and a second adhesive layer respectively provided on opposite sides of the foam. The first adhesive layer is bonded to the outer shell 10, and the second adhesive layer is bonded to the magnetic element 20.

[0060] Specifically, the foam is made of a material with good compressibility and elasticity to increase the movable distance of the magnetic component 20, that is, to increase the distance between the magnetic component 20 and the small back shell 52, thereby further effectively reducing the attraction between the magnetic component 20 and the small back shell 52, so as to further improve the speed and convenience of wireless module disassembly.

[0061] For example, the foam is made of any one of polyurethane foam, silicone foam, industrial silicone sponge, polyolefin foam, polyester foam, and rubber foam.

[0062] Specifically, the elastic element 21 has the same dimensions as the magnetic element 20. For example, both the elastic element 21 and the magnetic element 20 are configured as strips.

[0063] In some implementations, reference continues. Figure 3 The wireless module also includes a wireless circuit board 4, which is located inside the accommodating cavity, and the projection of the wireless circuit board 4 on the inner housing 11 does not overlap with the projection of the magnetic accumulator 20 on the inner housing 11.

[0064] It is understandable that the non-overlapping projection of the wireless circuit board 4 on the inner housing 11 and the projection of the magnetic member 20 on the inner housing 11 means that when the magnetic member 20 is attracted to the frame 53, the only thing separating the magnetic member 20 from the frame 53 is the inner housing 11. This arrangement ensures that the wireless circuit board 4 is not affected by the magnetic member 20, while also maintaining the magnetic attraction between the magnetic member 20 and the frame 53.

[0065] In some implementations, refer to Figure 6The display module also includes an all-in-one circuit board 6 located on the bezel 53. An all-in-one connector 60 is located on the side of the all-in-one circuit board 6 near the wireless module. A wireless connector 40 is located on the side of the wireless circuit board 4 near the inner housing 11. The inner housing 11 has a clearance portion 110 through which the wireless connector 40 passes to establish an electrical connection with an external device. It is understood that the external device here specifically refers to the all-in-one connector 60.

[0066] Specifically, when installing the wireless module, the operator needs to first ensure that the wireless connector 40 and the integrated connector 60 are aligned. Then, the wireless module is brought close to the small back cover 52. Simultaneously, the magnetic attachment 20 attracts the small back cover 52, and the wireless connector 40 is inserted into the integrated connector 60, thus establishing a connection. It is worth noting that the small back cover 52 also has a clearance portion to facilitate the passage of the wireless connector 40, which can be formed during the punching process of the small back cover 52. This will not be elaborated upon here.

[0067] In some embodiments, the position of the wireless connector 40 on the wireless circuit board 4 determines the shape of the clearance portion 110 on the inner housing 11. That is, the shape of the clearance portion 110 needs to be adapted to wireless devices in different positions. The clearance portion 110 can be configured as a recess or as a through hole.

[0068] In one embodiment, refer to Figure 2 , Figure 3 and Figure 4 The wireless connector 40 is located in the non-edge area of ​​the wireless circuit board 4. The clearance portion 110 can be configured to be a through hole in the inner housing 11. After passing through the through hole, the wireless connector 40 connects to an external device, that is, it is electrically connected to the all-in-one connector. Preferably, the wireless connector 40 is located in the middle of the wireless circuit board 4, and the clearance portion 110 is configured to be located in the middle of the inner housing 11 and to accommodate the through hole of the connection end of the wireless connector 40.

[0069] In one embodiment, refer to Figure 6 and Figure 7 The wireless connector 40 is located on one edge of the wireless circuit board 4. The clearance portion 110 can be configured as a groove formed on the edge of the inner housing 11. After passing through the groove, the wireless connector 40 connects to an external device, that is, it is electrically connected to the all-in-one connector 60 located on the frame 53.

[0070] In some embodiments, the position of the wireless connector 40 on the wireless circuit board 4 can also determine the position and number of magnetic suction components 20, the position and number of force-relieving components 3 corresponding to the magnetic suction components 20, and the number and position of receiving slots 101 for accommodating the force-relieving components 3. That is, the position and number of magnetic suction components 20 and force-relieving components 3 can be adapted to the specific design of the wireless circuit board 4 to meet actual needs.

[0071] Specifically, the bending portion 103 of the outer casing 10 includes a first bending portion and a second bending portion disposed opposite to each other, as well as a third bending portion and a fourth bending portion disposed opposite to each other. The first bending portion can be understood as being located at the upper edge of the flat panel (main body), the second bending portion at the lower edge of the flat panel (main body), the third bending portion at the left edge of the flat panel (main body), and the fourth bending portion at the right edge of the flat panel (main body). It is worth noting that the "up," "down," "left," and "right" here can be understood as the perspective of the operator during the disassembly of the wireless module, i.e., the perspective directly facing the frame 53 of the conference all-in-one machine.

[0072] In one embodiment, refer to Figure 3 and Figure 4 When the wireless connector 40 is located in the middle of the wireless circuit board 4, the two magnetic suction pieces 20 are respectively bonded to the edge areas of the main body near the third and fourth bends. The receiving groove 101 is formed at both ends of the first bend and corresponds to the magnetic suction pieces 20. The connecting part 30 of the force-relieving piece 3 is connected to the inner wall of the first bend, and part of the pressing part 31 of the force-relieving piece 3 extends out of the receiving groove 101 to bear external force.

[0073] Understandably, in this embodiment, when disassembling the wireless module, both hands can be pressed simultaneously on the two force-relieving parts 3. The two force-relieving parts 3 are inserted between the magnetic part 20 and the inner shell 11, reducing the attraction between the magnetic part 20 and the small rear shell 52, thereby quickly and easily removing the wireless module.

[0074] In one embodiment, when the wireless connector 40 is located at one edge of the wireless circuit board 4, a magnetic suction member 20, a receiving groove 101 corresponding to the magnetic suction member 20, and a force-relieving member 3 are each provided and located at the other edge of the wireless circuit board 4 opposite to the wireless connector 40. For example, referring to... Figure 6 and Figure 7 The wireless connector 40 is located at the edge corresponding to the fourth bend of the wireless circuit board 4 and the housing 10. The magnetic member 20 is bonded to the edge area of ​​the main body of the housing 10 near the third bend. The receiving groove 101 is opened at one end of the first bend near the magnetic member 20. The connecting part 30 of the unloading member 3 is connected to the inner wall of the first bend. A portion of the pressing part 31 of the unloading member 3 extends out of the receiving groove 101 to bear external force.

[0075] It is understood that in this embodiment, when the operator disassembles the wireless module, he only uses one hand to press the disassembly piece, and the force-relieving piece 3 is inserted between the magnetic suction piece 20 and the inner shell 11 to reduce the suction force, thereby removing the wireless module.

[0076] In some embodiments, depending on the actual needs of different scenarios, the receiving groove 101 and the force-relieving component 3 can also be set on any one of the second bend, the third bend, or the fourth bend, as long as they can increase the distance between the magnetic component 20 and the inner shell 11 to reduce the effect of the magnetic attraction force. These will not be listed individually here.
