Description

Technical Field

[0001] This utility model relates to the field of public service equipment, and in particular to a wall-mounted display device with a side-opening door structure. Background Technology

[0002] Self-service kiosks are a type of intelligent public service machine, primarily deployed to improve service efficiency, optimize the business environment, and facilitate public access to services. These kiosks integrate multiple functions, aiming to simplify procedures, reduce waiting times, and improve service quality and efficiency.

[0003] Existing public service smart machines, in terms of assembly structure, mainly include integrated and split types. Integrated structures, due to their high heat generation and automatic frequency reduction issues, are gradually being phased out of the market. Split-type devices consist of a screen body, internal components, a central fixing plate, and a back frame. During assembly, the internal components are fixed by the central fixing plate, then connected to the screen body, and finally the back frame is locked. During disassembly and maintenance, the connection between the back frame and the fixing plate is removed one by one, then the fixing plate is separated from the screen body, finally exposing the components.

[0004] The aforementioned public service equipment has a complex structure, numerous installation components, cumbersome assembly steps, and increased equipment weight. Therefore, this technical solution proposes a wall-mounted display device with a side-opening door structure. This side-opening door structure eliminates the need for a central panel, allowing the heat dissipation, electrical control, and main control components to be directly housed within the back frame. It can be quickly opened via a rotating opening assembly, saving assembly time and simplifying disassembly and maintenance procedures. Utility Model Content

[0005] The present invention aims to at least partially solve one of the technical problems in related technologies. Therefore, the main objective of this invention is to provide a wall-mounted display device with a side-opening door structure, which addresses the problems of complex assembly structures, lack of quick-opening mechanisms, and low maintenance efficiency in existing public service equipment.

[0006] To achieve the above objectives, this utility model provides a wall-mounted display device with a side-opening door structure, comprising a device body composed of a panel assembly and a back frame assembly.

[0007] The panel assembly and the back frame assembly open and close via a rotating opening and closing assembly.

[0008] The panel assembly includes a screen body and a panel frame body disposed on one side of the screen body.

[0009] The back frame assembly includes a back frame body, and the rotating opening and closing assembly includes a connecting sleeve frame disposed on one side edge of the panel frame body. A rotating shaft is provided inside the connecting sleeve frame. A mounting groove corresponding to the connecting sleeve frame is provided on one side of the back frame body, and through holes corresponding to the two ends of the rotating shaft are provided at both ends of the mounting groove.

[0010] As a further embodiment of this utility model, the main body of the device also includes a locking mechanism for locking the opening and closing of the back frame assembly and the panel assembly. The locking mechanism includes a locking member disposed on the other side edge of the panel frame main body and a lock head disposed on the other side of the back frame main body. The lock head is C-shaped and is connected to a lock hole on the outside of the back frame main body through a movable screw sleeve.

[0011] As a further embodiment of this utility model, the locking member is a frame structure with the opening facing upwards, and the lock head achieves locking and disengagement with the locking member through the rotation of the lock hole and the movable screw sleeve.

[0012] As a further embodiment of this utility model, both ends of the rotating shaft protrude outwards to the inward side and are provided with limiting portions for contacting the edge of the through hole.

[0013] As a further embodiment of this utility model, the back frame body is a double-layer frame structure, and the mounting groove is formed by bending once at the edge of the inner frame.

[0014] As a further embodiment of this invention, the number of rotating opening and closing components disposed between the panel assembly and the back frame assembly is at least three.

[0015] The beneficial effects of this utility model are as follows:

[0016] The wall-mounted display device with a side-opening door structure proposed in this utility model significantly reduces the overall steps compared to traditional methods through structural integration and mechanical optimization, making disassembly and maintenance more convenient. The panel assembly can be directly lifted by rotating the opening and closing component, without removing the back frame or separating the multi-layer structure, allowing direct access to internal components. This greatly shortens maintenance time and significantly reduces the weight and assembly complexity of the device. At the same time, the quick opening and closing mechanism improves maintenance efficiency, making it particularly suitable for high-traffic scenarios such as train stations and government service halls, effectively reducing equipment downtime and ensuring long-term operation of public services.

[0028] as follows:

[0029] Please see the appendix Figure 1-8 ,

[0030] The main structure includes a device body (1) consisting of a panel assembly (10) and a back frame assembly (11). The panel assembly (10) and the back frame assembly (11) are opened and closed by a rotating opening and closing assembly (12). The panel assembly (10) includes a screen body (100) and a panel frame body (101) disposed on one side of the screen body (100). The back frame assembly (11) includes a back frame body (110). The rotating opening and closing assembly (12) includes a connecting sleeve frame (121) disposed on one side edge of the panel frame body (101). A rotating shaft (122) is provided inside the connecting sleeve frame (121). A mounting groove (124) corresponding to the connecting sleeve frame (121) is provided on one side of the back frame body (110). Through holes (125) corresponding to the two ends of the rotating shaft (122) are provided at both ends of the mounting groove (124).

[0031] The working principle is as follows:

[0032] The panel assembly (10) includes the screen body (100) and components required only for display on the screen body (100). The back frame assembly (11) includes the back frame body (110) and most of the main components required for overall operation, such as the control board, power adapter, and heat dissipation device, which are located in the back frame body (110). The rotating opening and closing assembly (12) serves to open and close the panel assembly (10) and the back frame assembly (11). During assembly, the rotating opening and closing assembly (12) is simply installed on the edges of the two modules (panel assembly (10) and back frame assembly (11)). The two modules are then connected by the rotating opening and closing assembly (12), and some of the wiring plugs of the panel assembly (10) are then plugged into the components in the back frame assembly (11). When disassembly and maintenance are required, the panel assembly (10) can be opened directly, and the panel assembly (12) can be locked.

[0033] Traditional public service equipment faces significant efficiency bottlenecks in assembly and maintenance. Taking a split-type structure as an example, it adopts a multi-layered design consisting of a screen body (100), internal components, a central fixing plate, and a back frame. Assembly requires first fixing the internal components to the central plate, then connecting them to the screen body (100), and finally locking the back frame. The process is cumbersome and relies on a large number of connectors, resulting in bulky equipment and limited heat dissipation. Maintenance requires disassembling the back frame, central plate, and other multi-layered structures in reverse, which is time-consuming and labor-intensive. Especially in high-frequency public places, downtime for maintenance directly affects service continuity.

[0034] This solution innovatively simplifies the equipment architecture through a side-opening door structure, eliminating the middle plate design and directly integrating the heat dissipation module, electrical control system, and main control unit into the back frame assembly (11). The panel and back frame are quickly connected by a rotating opening and closing assembly (12). During assembly, the connecting sleeve (121) on one side of the panel assembly (10) is simply inserted into the mounting groove (124) of the back frame body (110), and the two ends of the rotating shaft (122) are aligned with the through hole (125) to complete the main body docking. Then, only the necessary wiring needs to be plugged in. The overall steps are greatly reduced compared to the traditional method, and disassembly and maintenance are more convenient. The panel assembly (10) can be directly opened by rotating the opening and closing assembly (12), and the internal components can be directly accessed without removing the back frame or separating the multi-layer structure, which greatly shortens the maintenance time. In addition, the locking mechanism (2) uses a "C" type lock head (203) and a movable screw sleeve (202) to fix or unlock the panel and back frame with one hand, which ensures stability and improves the convenience of operation. The limiting parts (123) at both ends of the pivot (122) and the double-layer frame design of the back frame further enhance the structural reliability and prevent the components from shifting or loosening during the opening and closing process.

[0035] Compared to traditional technologies, this solution significantly reduces equipment weight and assembly complexity through structural integration and mechanical optimization. At the same time, it improves maintenance efficiency through a quick-opening and closing mechanism, making it particularly suitable for high-traffic scenarios such as train stations and government service halls. This effectively reduces equipment downtime and ensures long-term operation of public services.

[0036] Reference Appendix Figure 3 , 7 8. A preferred embodiment of the present invention: The main body (1) of the device further includes a locking mechanism (2) for locking the opening and closing of the back frame assembly (11) and the panel assembly (10). The locking mechanism (2) includes a locking member (200) disposed on the other side edge of the panel frame main body (101) and a lock head (203) disposed on the other side of the back frame main body (110). The lock head (203) is C-shaped and is connected to the lock hole (201) outside the back frame main body (110) through a movable screw sleeve (202).

[0037] The locking mechanism (2) uses a "C"-shaped lock head (203) to cooperate with the locking element (200) on the panel frame to achieve a stable lock between the panel and the back frame. When the device needs to be closed, simply align the "C"-shaped lock head (203) on the back frame with the locking element (200) on the side of the panel with the opening facing upwards, and rotate the movable screw sleeve (202) to make the lock head (203) engage inside the locking element (200), completing the single-sided fixation like a padlock. When disassembling, simply rotate the screw sleeve in the opposite direction to quickly separate the parts. Compared with the traditional multi-screw fixing method, this design does not require tools and can be completed within 3 seconds with one hand. This avoids the risk of losing screws and solves the problem of cumbersome disassembly and assembly of traditional structures, making it particularly suitable for frequent maintenance scenarios. In addition, the bent structure of the "C"-shaped lock head (203) can adapt to the frame space of the locking element (200) when locking, and adjust the tightness with the screw sleeve to ensure that the device does not wobble when closed.

[0038] Reference Appendix Figure 7 , 8 In a preferred embodiment of this utility model, the locking member (200) is a frame structure with the opening facing upward. The lock head (203) locks and separates from the locking member (200) by rotating the lock hole (201) and the movable screw sleeve (202).

[0039] The upward-opening frame structure acts like a "slot," facilitating the vertical insertion and positioning of the "C"-shaped lock head (203). When the movable sleeve (202) is rotated, the lock head (203) moves laterally along the lock hole (201), locking into the frame to complete the locking process. Reverse rotation causes the lock head (203) to disengage, achieving separation. The entire process requires no tools and can be completed with a single hand rotation, simplifying operation and avoiding the cumbersome process of traditional screw fixing.

[0040] Reference Appendix Figure 5 , 6 In a preferred embodiment of the present invention, both ends of the rotating shaft (122) protrude outward on one side to provide a limiting part (123) for contacting the edge of the through hole (125).

[0041] The limiting parts (123) at both ends of the pivot (122) protrude outward to form a limiting structure. When the pivot (122) is inserted into the through hole (125) of the back frame, the limiting parts (123) will fit tightly against the edge of the through hole (125) to prevent the pivot (122) from sliding up and down or accidentally falling off. This design avoids the loosening problem caused by frequent opening and closing of traditional pivots, and ensures that the panel and the back frame are always accurately aligned. The opening and closing process is smoother and more stable, and no additional reinforcing parts are required, simplifying the assembly steps.

[0042] Reference Appendix Figure 3 , 4In a preferred embodiment of this utility model, the back frame body (110) is a double-layer frame structure, and the mounting groove (124) is formed by bending once at the edge of the inner frame.

[0043] The double-layer frame structure forms the mounting groove (124) by bending the inner frame edge once, which not only strengthens the overall support of the back frame, but also ensures the accuracy and reliability of the mounting position, while reducing additional parts and processing steps, reducing production costs and improving assembly efficiency.

[0044] Reference Appendix Figure 3 In a preferred embodiment of the present invention, the number of rotating opening and closing components (12) disposed between the panel component (10) and the back frame component (11) is at least 3.

[0045] Setting at least 3 sets of rotating opening and closing components (12) can disperse the force pressure during opening and closing, avoid deformation caused by single-point overload, enhance the overall structural stability, and ensure that the opening and closing trajectory of the panel is consistent and does not deviate. Especially in large-size equipment, it can significantly improve the smoothness of opening and closing and long-term durability.

[0046] The above are merely preferred embodiments of the present utility model and do not limit the patent scope of the present utility model. Any equivalent structural transformations made using the contents of the present utility model specification and drawings under the concept of the present utility model, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
