[0006] The display screen assembly is detachably mounted in the mounting slot. A second spring-loaded connector and a slot are provided on the side of the display screen assembly facing the frame. The second spring-loaded connector is used for electrical connection with the first spring-loaded connector. The display screen assembly is magnetically connected to the bottom wall of the mounting slot.

[0007] The snap-fit ​​component is disposed in the mounting slot. The snap-fit ​​component and the slot have a snap-fit ​​state and a release state. In the snap-fit ​​state, the snap-fit ​​component snaps into the slot to connect the display screen assembly and the frame. In the release state, the snap-fit ​​component disengages from the slot.

[0008] In one embodiment, one of the frame and the display screen assembly is provided with at least one magnetic connector, and the other of the frame and the display screen assembly is provided with at least one magnetic connector base, with the magnetic connector and the magnetic connector base corresponding to each other.

[0009] In one embodiment, the slot extends along a first direction, and the snap-fit ​​assembly includes:

[0010] A fixing seat is disposed in the mounting groove, and a sliding groove extending along the first direction is formed on the top of the fixing seat;

[0011] Two snap-fit ​​structures are provided, and the two snap-fit ​​structures are spaced apart in the slide groove along the first direction. The two snap-fit ​​structures are connected by an elastic element, and the two snap-fit ​​structures protrude upward from the slide groove.

[0012] In the engaged state, the two latching structures slide to both ends of the slide groove and are correspondingly engaged with both ends of the slot. In the released state, the latching structures disengage from the slot.

[0013] In one embodiment, the snap-fit ​​structure includes a connecting portion and a hook portion disposed on the connecting portion, the hook portion extending in a direction away from the other snap-fit ​​structure, so as to snap into the slot in the snap-fit ​​state.

[0014] In one embodiment, the hook portion is provided with a guide slope on the side facing the display screen assembly, and the guide slope on each of the latching structures is inclined in a direction away from the other latching structure.

[0015] In one embodiment, the display assembly further includes a drive rod that protrudes from the side of the display assembly facing the mounting groove. The snap-fit ​​assembly further includes a pull ring, one end of which is connected to one side of one of the snap-fit ​​structures, and the other end of which is connected to one side of the other snap-fit ​​structure. The middle of the pull ring protrudes from the side away from the fixing seat to form a gap with the fixing seat.

[0016] When the display screen assembly is installed in the mounting slot, the drive rod is inserted downward into the interval, and when the display screen assembly is removed, the drive rod drives the pull ring to move in the second direction away from the fixed base, so as to pull the two buckle structures closer to each other and disengage them from the slot.

[0017] In one embodiment, the drive rod includes a support portion and a locking portion.

[0019] In one embodiment, a heat dissipation vent is provided on the bottom wall of the mounting groove, and a waterproof and breathable membrane is provided at the heat dissipation vent.

[0020] In this invention, the frame has an upward-opening mounting groove. A communication circuit board and a first spring pin connector connected to the circuit board are installed in the mounting groove. After the display panel is placed in the mounting groove, it automatically adheres to the bottom wall of the groove, allowing the second spring pin connector on the display panel to automatically connect with the first spring pin connector in the mounting groove, thus enabling signal conduction. This allows the display panel to obtain the power and signals required for operation without complicated plugging and unplugging operations, improving installation efficiency. The display panel is magnetically connected to the mounting groove, making the adsorption process simpler and more convenient. In addition, when the display panel is installed in the mounting groove, the locking component engages with the locking slot on the display panel, preventing the display panel from becoming loose during use and causing poor contact, which would affect the display display. This ensures the stability and reliability of the circuit connection. When it is necessary to remove the display panel, the locking component is adjusted to the released state, releasing the locking of the display panel. The display panel can be easily removed under magnetic force only, making the operation convenient and facilitating the installation, removal, and maintenance of the display panel, thus shortening maintenance time.

[0036] As an important terminal for information presentation and interaction, the display screen plays a vital role. Traditional displays screens generally use screws to fix the various components together. This assembly method makes the disassembly process more cumbersome and complicated, requiring the use of a special screwdriver to unscrew each screw one by one. For some large displays screens, it may even take several days to complete the disassembly of the screws, reducing maintenance and repair efficiency. Moreover, the disassembly process may damage other components of the display screen.

[0037] This utility model proposes a display device.

[0038] Please see Figure 1 and Figure 2 In one embodiment of this utility model, the display device includes a frame 100, a display screen assembly 200, and a snap-fit ​​assembly 300. The frame 100 has an upward-opening mounting groove, in which a first spring pin connector 110 is disposed. The display screen assembly 200 is detachably disposed in the mounting groove. A second spring pin connector 210 and a slot 220 are disposed on the side of the display screen assembly 200 facing the frame 100. The second spring pin connector 210 is used for electrical connection with the first spring pin connector 110. The display screen assembly 200 is magnetically connected to the bottom wall of the mounting groove. The snap-fit ​​assembly 300 is disposed in the mounting groove. The snap-fit ​​assembly 300 and the slot 220 have a snap-fit ​​state and a release state. In the snap-fit ​​state, the snap-fit ​​assembly 300 snaps into the slot 220 to connect the display screen assembly 200 and the frame 100. In the release state, the snap-fit ​​assembly 300 disengages from the slot 220.

[0039] In this invention, the frame 100 has an upward-opening mounting groove. A communication circuit board (not shown) and a first spring-loaded connector 110 connected to the circuit board are disposed within the mounting groove. After the display panel 200 is placed in the mounting groove, it automatically adheres to the bottom wall of the groove, causing the second spring-loaded connector 210 on the display panel 200 to automatically connect electrically with the first spring-loaded connector 110 in the mounting groove, enabling signal conduction. This allows the display panel 200 to obtain the power and signals required for operation, eliminating the need for complex plugging and unplugging operations and improving installation efficiency. The display panel 200 is magnetically connected to the mounting groove, allowing for blind insertion without the need for angle alignment. This makes the adsorption process simpler and more convenient. In addition, when the display panel 200 is installed in the mounting slot, the snap-fit ​​component 300 snaps into the slot 220 on the display panel 200, preventing the display panel 200 from becoming loose during use and causing poor contact, which would affect the display of the display panel 200 and ensure the stability and reliability of the circuit connection. When it is necessary to remove the display panel 200, the snap-fit ​​component 300 is adjusted to the release state to release the lock on the display panel 200. The display panel 200 can be easily removed under magnetic force only. The operation is convenient and facilitates the installation, removal and maintenance of the display panel 200, shortening the maintenance time.

[0040] Specifically, the frame 100 serves as the basic support structure for the display panel assembly 200, providing a stable installation environment for the display panel assembly 200. Its shape and material are not limited, but the preferred material is plastic, and the preferred shape is a rectangular structure. A mounting groove is formed within the frame 100, where the depth direction is defined as vertical. A communication circuit board and a first spring-loaded connector 110 connected to the circuit board are disposed within the mounting groove. The first spring-loaded connector 110 can be configured as a spring-loaded pogo pin. The display panel assembly 200, as the core unit for realizing the display function, is preferably a rectangular structure. One or two display panel assemblies 200 can be provided, and the number is not limited. In this embodiment, there are two display panel assemblies 200 with identical structures. Each display panel assembly 200 is electrically connected to the mounting groove, allowing each display panel assembly 200 to work independently. The front of the display panel assembly 200, i.e., the far... The side facing the mounting slot is used to display images and information. The display panel 200 contains control circuits for the communication module, which will not be described in detail here. Each display panel 200 has a second spring pin connector 210 on the side facing the mounting slot. The second spring pin connector 210 is electrically connected to the internal control circuit. The second spring pin connector 210 is configured as a spring pin pogo pin. When the display panel 200 is placed in the mounting slot, the spring pin of the second spring pin connector 210 contacts the spring pin of the first spring pin connector 110, realizing the conduction between the control circuit inside the display panel 200 and the communication circuit board in the mounting slot. This allows the display panel 200 to obtain the power and signal required for operation. Each display panel 200 works independently. Even if one display panel 200 fails, it can be disassembled and repaired separately while the other display panel 200 continues to work normally, making it more widely applicable.

[0041] In an embodiment of this utility model, one of the frame 100 and the display screen group 200 is provided with at least one magnetic connector 400, and the other of the frame 100 and the display screen group 200 is provided with at least one magnetic connector 410, with the magnetic connector 400 and the magnetic connector 410 correspondingly arranged.

[0042] Please refer to Figure 1 and Figure 2Specifically, the magnetic connector 410 is equipped with a magnet and metal contacts, and the magnetic connector 400 can be made of metal with internal connection holes corresponding to the metal contacts. The magnetic connector 410 and the magnetic connector 400 can also use permanent magnets, such as N52 grade neodymium iron boron, without limitation. When installing the display screen assembly 200, the attraction force generated by the magnet will attract the magnetic connector 400, allowing the display screen assembly 200 to quickly and accurately approach the installation position, and the metal contacts are inserted into the contact connection holes. After the magnetic connection is completed, the first spring pin connector 110 and the second spring pin connector 210 are connected, realizing automatic circuit connection without complicated plugging and unplugging operations or screws, improving installation efficiency and ensuring the stability and reliability of circuit connection.

[0043] In an embodiment of this utility model, the slot 220 extends along a first direction, and the snap-fit ​​assembly 300 includes:

[0044] A fixing seat 310 is disposed in the mounting groove, and a sliding groove 311 extending along the first direction is formed on the top of the fixing seat 310;

[0045] Two snap-fit ​​structures 320 are provided, and the two snap-fit ​​structures 320 are spaced apart in the slide groove 311 along the first direction. The two snap-fit ​​structures 320 are connected by an elastic member 340, and the two snap-fit ​​structures 320 protrude upward from the slide groove 311.

[0046] In the latching state, the two latching structures 320 slide to the two ends of the slide groove 311 and are correspondingly latched to the two ends of the slot 220. In the releasing state, the latching structure 320 disengages from the slot 220.

[0047] Please refer to Figure 3 and Figure 4The slot 220 is rectangular at the bottom of the display assembly 200, and there are no electronic components inside the display assembly 200 near the slot 220. The snap-fit ​​assembly 300 includes a fixing base 310, on which a sliding groove 311 is provided. The length of the sliding groove 311 is consistent with the length direction of the slot 220. Two snap-fit ​​structures 320 are provided protruding upward in the sliding groove 311, and the snap-fit ​​structures 320 are slidably disposed in the sliding groove 311. When the display assembly 200 is placed in the mounting slot from top to bottom, the magnetic connector 400 and the magnetic connector 410 are magnetically connected, and the slot 220 corresponds to the snap-fit ​​assembly 300. As the slot 220 descends, the inner walls at both ends of the slot 220 abut against the latching structure 320, driving the two latching structures 320 to move closer to each other until the display assembly 200 is completely placed in the mounting slot. Then, the elastic element 340 is compressed and rebounds, allowing the two latching structures 320 to slide within the slide groove 311 to both ends of the slide groove 311. Since the latching structure 320 protrudes upward from the slide groove 311, it extends upward into the slot 220 and engages with the inside of both ends of the slot 220, making the connection between the display assembly 200 and the frame 100 more stable and the image display more stable.

[0048] In one embodiment, the elastic element 340 is a spring.

[0049] In one embodiment, the bottom of the latching structure 320 is inclined upward. When the display assembly 200 is taken out upward, the slot 220 drives the two latching structures 320 to move toward each other, so that the latching structures 320 release the slot 220, thereby releasing the display assembly 200. The latching component 300 not only enhances the stability of the installation of the display assembly 200, but also enables quick disassembly and installation, making it convenient to maintain the display assembly 200.

[0050] In an embodiment of this utility model, the snap-fit ​​structure 320 includes a connecting part 321 and a hook part 322 disposed on the connecting part 321. The hook part 322 extends in a direction away from the other snap-fit ​​structure 320 so as to snap into the slot 220 in the snap-fit ​​state. The connecting part 321 is disposed in the slide groove 311, and the hook part 322 is disposed above the connecting part 321 and protrudes upward from the slide groove 311. The two ends of the elastic member 340 are elastically connected to the two connecting parts 321 respectively. The two hook parts 322 extend in a direction away from each other. The entire snap-fit ​​structure 320 is "L" shaped. When in the snap-fit ​​state, the hook part 322 extends into the slot 220 and snaps into the slot 220, which can prevent the display screen assembly 200 from falling out of the mounting groove and improve the stability of the installation.

[0051] Please refer to Figure 3 and Figure 4In an embodiment of this utility model, the hook portion 322 is provided with a guide slope 3221 on the side facing the display screen assembly 200. The guide slope 3221 on each of the latching structures 320 is inclined away from the other latching structure 320. When the display screen assembly 200 is placed into the mounting groove from top to bottom, the edge of the slot 220 first contacts the guide slope 3221 on the hook portion 322. As the display screen assembly 200 descends, the hook portion 322 slides toward the middle of the slide groove 311. When the display screen assembly 200 is completely placed in the mounting groove, the edge of the slot 220 no longer abuts against the guide slope 3221 of the hook portion 322. The elastic member 340 rebounds, causing the two hook portions 322 to move away from each other. The hook portion 322 engages with the inside of the slot 220. The setting of the guide slope 3221 facilitates the precise installation of the latching structure 320.

[0052] Please refer to Figure 3 In an embodiment of this utility model, the display screen assembly 200 further includes a drive rod 230, which protrudes from the side of the display screen assembly 200 facing the mounting groove. The snap-fit ​​assembly 300 further includes a pull ring 330, one end of which is connected to one side of one of the snap-fit ​​structures 320, and the other end is connected to one side of the other snap-fit ​​structure 320. The middle of the pull ring 330 protrudes from the side away from the fixing seat 310 to form a gap with the fixing seat 310.

[0053] When the display screen assembly 200 is installed in the mounting slot, the drive rod 230 is inserted downward into the interval. When the display screen assembly 200 is removed, the drive rod 230 drives the pull ring 330 to move in the second direction away from the fixed base 310, so as to pull the two buckle structures 320 closer to each other and disengage them from the buckle slot 220.

[0054] Specifically, please refer to Figure 3The mounting base has an upward-facing groove 311 with a through-hole 312 on the horizontal side. A pull ring 330 is arc-shaped, with one end extending into the through-hole 312 and towards the groove 311, connecting to the connecting part 321 within the groove 311. The other end of the pull ring 330 extends into the through-hole 312 and connects to another connecting part 321 within the groove 311. The middle portion of the pull ring 330 is outside the through-hole 312 and has a horizontal gap with the mounting base 310. The drive rod 230 protrudes from the bottom of the display assembly 200. Extending towards the mounting slot, the drive rod 230 extends downward into the gap between the pull ring 330 and the fixed base 310, and abuts against the pull ring 330. The lifting and lowering of the drive rod 230 drives the pull ring 330 to move away from the fixed base 310. When it is necessary to remove the display assembly 200, the display assembly 200 moves upward, and the drive rod 230 abuts against the pull ring 330 to move it away from the fixed base 310. When the pull ring 330 moves away from the fixed base 310, it pulls the two connecting parts 321 to move towards the middle, thereby driving the hook part 32. 2. Move towards the center, thereby releasing the engagement of the slot 220 and releasing the display assembly 200. When the display assembly 200 needs to be installed, the display assembly 200 moves downward in alignment, driving the pull ring 330 to move away from the fixing base 310. The pull ring 330 pulls the two connecting parts 321 so that they move closer to each other in the slide groove 311, and the two hook parts 322 move closer to each other until the slot 220 abuts against the slide groove 311. The drive rod 230 releases the abutment of the pull ring 330, and with the rebound of the elastic element 340... This causes the two connecting parts 321 to move away from each other, and then the two hook parts 322 to move towards the two ends of the slide groove 311, thereby engaging the slot 220. The engagement component 300 makes the installation of the display assembly 200 and the frame 100 more stable, and does not require tools such as screwdrivers. When the display assembly 200 is taken out upwards, the drive rod 230 directly pulls the pull ring 330 to release it from the lock on the display assembly 200, and then the display assembly 200 can be easily disassembled under magnetic force, shortening maintenance time and improving maintenance efficiency.

[0055] Please refer to Figure 3In one embodiment, the drive rod 230 includes a support portion 231 and a locking portion 232. The support portion 231 is located at one end of the display screen assembly 200 facing the mounting groove, and the locking portion 232 is located at the end of the support portion 231 away from the display screen assembly 200. The locking portion 232 is bent and connected to the support portion 231, and the support portion 231 and the locking portion 232 cooperate to form a sickle shape. When installing the display screen assembly 200, the locking portion 232 first contacts the pull ring 330. Since the locking portion 232 is inclined, as the locking portion 232 descends, the inclined surface drives the pull ring 330 to move away from the fixed base 310. This allows the two latching structures 320 to approach each other, facilitating the docking of the slot 220 with the slide groove 311. At this time, the pull ring 330 bypasses the end of the engaging part 232 and is no longer abutted by the engaging part 232. The elastic member 340 rebounds, causing the two latching structures 320 to move away from each other until they reach both ends of the slide groove 311. The hook part 322 protrudes from the slide groove 311 and engages with the slot 220, preventing the display screen assembly 200 from disengaging from the mounting groove in the vertical direction. In one embodiment, the other side of the engaging part 232 is also inclined, so that when the display screen assembly 200 is moved upward, the engaging part 232 abuts against the pull ring 330 to drive the pull ring 330 to move, improving the convenience of operation.

[0056] Please refer to Figure 1 and Figure 2 In an embodiment of this utility model, at least one limiting protrusion 500 is provided on the inner wall of the mounting groove, the limiting protrusion 500 extending along the depth of the mounting groove, and at least one limiting groove 510 is provided on the outer periphery of the display panel assembly 200. When the display panel assembly 200 is connected to the frame 100, the limiting protrusion 500 is located within the limiting groove 510. When the display panel assembly 200 needs to be placed, the limiting protrusion 500 and the limiting groove 510 are aligned. The setting of the limiting protrusion 500 and the limiting groove 510 provides guidance for the installation of the display panel assembly 200, ensuring that the display panel assembly 200 can be quickly and accurately installed in the designated position, avoiding misalignment, ensuring precise docking between the display panel assembly 200 and the frame 100, improving the installation speed, and preventing the display panel assembly 200 from shifting after installation, ensuring stability after installation. In one embodiment, the limiting protrusion 500 may also protrude from the outer periphery of the display panel assembly 200, and the limiting groove 510 may be located on the inner wall of the mounting groove.

[0057] In the embodiments of this utility model, please refer to Figure 1A heat dissipation vent 120 is provided on the bottom wall of the mounting groove. A waterproof and breathable membrane is provided at the heat dissipation vent 120. The number and shape of the heat dissipation vent 120 are not limited and can be circular or rectangular. The waterproof and breathable membrane is provided at the heat dissipation vent 120 and is tightly fitted to the heat dissipation vent 120 to ensure its sealing and breathability. It can not only prevent liquid intrusion, but also allow heat from the air to pass through, increasing the heat dissipation area of ​​the frame 100, accelerating the dissipation of heat from the internal electronic components, and improving the performance and reliability of the operation. In addition, the waterproof and breathable membrane can effectively prevent external water, dust and other foreign objects from entering the mounting groove through the heat dissipation vent 120 and causing damage to the internal components.
