Description

Technical Field

[0001] This utility model relates to the field of server racks, and more specifically, to a transparent screen server rack with an ultra-narrow bezel. Background Technology

[0002] Currently, various cabinet devices such as book lending machines, vending machines, and smart storage cabinets generally integrate displays on their cabinet doors to achieve functions such as information display, operation guidance, and human-computer interaction. With the development of technology and the improvement of user experience requirements, transparent displays are gradually being applied to such devices. Transparent displays allow users to directly observe the items inside the cabinet (such as the status of goods, books, or equipment) through the screen. This enables human-computer interaction while allowing users to intuitively obtain information about the items inside the cabinet, improving ease of use and making it easier for users to make decisions such as whether to purchase or borrow items based on their status.

[0003] However, existing cabinets using transparent displays still have significant problems. On the one hand, the display needs to be connected to electronic components such as the main control circuit board and driver board at the back. These non-transparent circuit boards are usually fixed directly to the inside of the cabinet door and located behind the display, which seriously obstructs the items inside the cabinet, weakens the original visual advantages of the transparent screen, affects the user's clear identification of the items inside the cabinet, and reduces the user experience.

[0004] On the other hand, the current circuit boards and their supporting structures are all built into the cabinet doors. This arrangement also increases the overall thickness of the cabinet doors, which not only affects the simplicity and slim design of the cabinet appearance, but may also increase the weight of the cabinet doors due to the bulky structure. In addition, some circuit boards are also placed on the side away from the hinge (rotary axis), which will bring additional load to the hinge (rotary axis). Long-term use may easily cause problems such as cabinet doors sagging and difficulty in opening and closing.

[0005] Therefore, how to effectively avoid visual interference from circuit components to the transparent display area while ensuring the stability of circuit connection and normal operation of display function, and at the same time achieve the thinness and reliability of cabinet door structure, has become a technical problem that urgently needs to be solved in this field.

[0006] Therefore, it is necessary to propose a transparent screen cabinet with an ultra-narrow bezel to solve the above problems. Utility Model Content

[0007] To overcome at least one of the defects (deficiencies) of the prior art, this utility model provides a transparent screen cabinet with an ultra-narrow bezel.

[0008] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows: a transparent screen cabinet with an ultra-narrow bezel, comprising a cabinet body, a data communication device, a cabinet door frame, and a display screen;

[0009] The cabinet door frame is slidably mounted on the cabinet body via a pivot, and the display screen is mounted on the cabinet door frame.

[0010] The cabinet door frame is provided with one or more external circuit board clips in the direction facing the cabinet body, and the width of the circuit board clips is smaller than the width of the cabinet door frame.

[0011] The data communicator is housed within the cabinet. One end of the circuit board is connected to the data communicator via a wire, and the other end is connected to the display screen via a wire. Compared to existing technologies, by externally mounting one or more circuit boards connected to the display screen on the cabinet door frame near the hinge, the circuit boards do not obstruct the viewer's view of the products inside the cabinet. Furthermore, since the circuit boards are externally mounted on the cabinet door frame, the door frame only needs to cover the display screen, thus reducing the overall thickness and weight of the door frame. Moreover, with the circuit boards externally mounted, maintenance personnel do not need to disassemble the door frame when replacing or repairing the circuit boards, saving maintenance time. Additionally, because the circuit boards are mounted on the outside of the door frame near the hinge, the center of gravity is shifted to one side of the door frame, effectively preventing sagging and difficulty in opening and closing the door frame on the side furthest from the hinge due to excessive weight after prolonged use.

[0012] Furthermore, the inner side of the cabinet door frame is provided with a circuit board card mounting base, and the circuit board card is set in the circuit board card mounting base. The circuit board card mounting base can protect the circuit board card.

[0013] Furthermore, the width of the circuit board card mounting base is less than or equal to the width of the cabinet door frame. Since the width of the circuit board card mounting base is less than or equal to the width of the cabinet door frame, the circuit board card mounting base and the circuit board card, after being installed, will not obstruct the buyer's view of the items inside the cabinet, thus enhancing the buyer's user experience.

[0014] Furthermore, the circuit board mounting base includes a circuit board mounting cover, a reset spring, and a circuit board mounting base disposed on the cabinet door frame;

[0015] The circuit board mounting cover is rotatably mounted on the circuit board mounting base;

[0016] The circuit board mounting cover is provided with a first positioning clamping block, a second positioning clamping block, and a mounting through hole for wires to pass through.

[0017] The circuit board mounting base includes a circuit board mounting base body, a first limiting hole, a second limiting hole, and an isolation plate for supporting the circuit board. The first limiting hole and the second limiting hole are respectively disposed on both sides of the circuit board mounting base body.

[0018] The isolation plate is disposed on the circuit board card mounting base body between the first limiting hole and the second limiting hole;

[0019] The first and second positioning clamping blocks are movably disposed on both sides of the circuit board mounting cover, and each of the first and second positioning clamping blocks is provided with a positioning protrusion. When the circuit board mounting cover is disposed on the circuit board mounting base, after the first and second positioning clamping blocks on the circuit board mounting cover are pressed together, the positioning protrusions on the first and second positioning clamping blocks are respectively engaged with the first and second limiting holes of the circuit board mounting base body. One end of the reset spring is connected to the circuit board mounting base body, and the other end abuts against the first and second positioning clamping blocks respectively. Because the circuit board mounting cover is provided with the first and second positioning clamping blocks, the positioning protrusions on the first and second positioning clamping blocks are respectively engaged with the first and second limiting holes of the circuit board mounting base body. The circuit board mounting cover is equipped with a first positioning clamping block, a second positioning clamping block, and a mounting through hole for wires to pass through. Therefore, when the circuit board mounting cover is locked onto the circuit board mounting base body, the positioning protrusions on the first and second positioning clamping blocks engage with the first and second limiting holes on the circuit board mounting base body. When the positioning protrusions on the circuit board mounting cover separate from the first and second limiting holes on the circuit board mounting base body, the circuit board mounting cover separates from the circuit board mounting base body. The reset spring can spring open the positioning protrusions on the first and second positioning clamping blocks, thereby better separating the positioning protrusions on the first and second positioning clamping blocks from the first and second limiting holes.

[0020] Furthermore, the circuit board mounting base body is provided with a limiting groove, and the reset spring is set in the limiting groove. By setting the limiting groove, the compression deformation of the reset spring can be limited, which is simple and practical.

[0021] Furthermore, the circuit board mounting base body and the limiting groove are an integral structure, which can effectively simplify the structure of the circuit board mounting base.

[0022] Furthermore, the isolation plate, circuit board mounting cover, and circuit board mounting base are all provided with heat dissipation holes, which facilitate heat dissipation of the circuit board.

[0023] Furthermore, the circuit board mounting cover is equipped with a press unlocker. By using the press unlocker, the circuit board mounting cover can be easily unlocked, allowing the circuit board mounting cover to be opened, which facilitates maintenance personnel to inspect the circuit board inside the circuit board mounting base.

[0024] Furthermore, the press-to-unlock device includes a presser, a press spring, and an unlocking post;

[0025] The presser is pressable on the circuit board mounting cover via a pressing spring. The unlocking post is located at the bottom of the presser. When the presser is pressed down, the unlocking post presses against the positioning protrusions of the first and second positioning blocks, causing the positioning protrusions on the first and second positioning blocks to separate from the first and second limiting holes on the circuit board mounting base body. In use, maintenance personnel can press the presser to depress the pressing spring, causing the unlocking post to press down on the positioning protrusions of the first and second positioning blocks, thereby separating the positioning protrusions from the first and second limiting holes on the circuit board mounting base body, thus realizing the opening control of the circuit board mounting cover.

[0026] Furthermore, the display screen is a transparent screen. Because the display screen is transparent, the buyer can interact with the computer through the transparent screen while also observing the items inside the cabinet, which is simple and convenient.

[0027] Compared with the prior art, the beneficial effects of this utility model's technical solution are:

[0028] This utility model discloses an ultra-narrow bezel transparent screen cabinet. Compared with the prior art, by externally placing one or more circuit boards connected to the display screen on the inner side of the cabinet door frame near the hinge, the circuit boards will not affect the viewer's viewing of the products inside the cabinet. In addition, since the circuit boards are externally placed on the cabinet door frame, the cabinet door frame only needs to cover the display screen, thus reducing the overall thickness and weight of the cabinet door frame. Furthermore, with the circuit boards externally placed, maintenance personnel do not need to disassemble the cabinet door frame when replacing or repairing the circuit boards, saving maintenance time. Moreover, since the circuit boards are placed on the outer side of the cabinet door frame near the hinge, the center of gravity is shifted to one side of the cabinet door frame, which can effectively prevent the cabinet door frame from sagging or having difficulty opening and closing due to the greater weight on the side away from the hinge after long-term use.

Detailed Implementation

[0038] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0039] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can be described as the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0040] like Figure 1-3As shown, a transparent screen cabinet with an ultra-narrow bezel includes a cabinet body 1, a data communicator 2, a cabinet door frame 3, and a display screen 4. The cabinet door frame 3 is closable on the cabinet body 1 via a pivot 5, and the display screen 4 is mounted on the cabinet door frame 3. The cabinet door frame 3 has one or more external circuit board cards 6 facing the cabinet body 1, the width of which is less than the width of the cabinet door frame 3. The data communicator 2 is located inside the cabinet body 1. One end of each circuit board card 6 is connected to the data communicator 2 via a wire, and the other end is connected to the display screen 4 via a wire. Compared to existing technologies, by externally mounting one or more circuit board cards 6 connected to the display screen 4 on the inner side of the cabinet door frame 3 near the pivot 5, [the following is a description of the improved design]. This circuit board 6 will not affect the viewer's viewing of the products inside the cabinet body 1. In addition, since the circuit board 6 is externally mounted on the cabinet door frame 3, the cabinet door frame 3 only needs to cover the display screen 4. Therefore, the overall thickness and weight of the cabinet door frame 3 are reduced. Furthermore, with the circuit board 6 externally mounted, maintenance personnel do not need to disassemble the cabinet door frame 3 when replacing or repairing the circuit board 6, saving maintenance time. In addition, since the circuit board 6 is located on the outside of the cabinet door frame 3 near the pivot 5, the center of gravity is shifted to one side of the cabinet door frame 3. This can effectively prevent the cabinet door frame 3 from sagging or having difficulty opening and closing due to the greater weight on the side away from the pivot 5 after long-term use.

[0041] like Figure 4-8 As shown, a circuit board card mounting base 7 is provided on the inner side of the cabinet door frame 3, and the circuit board card 6 is set in the circuit board card mounting base 7. The circuit board card mounting base 7 can protect the circuit board card 6. The width of the circuit board card mounting base 7 is less than or equal to the width of the cabinet door frame 3. Since the width of the circuit board card mounting base 7 is less than or equal to the width of the cabinet door frame 3, the circuit board card mounting base 7 and the circuit board card will not obstruct the view of the items in the cabinet after they are set up, thus enhancing the user experience.

[0042] In this utility model, the circuit board mounting base 7 includes a circuit board mounting cover 8, a reset spring 9, and a circuit board mounting base 10 disposed on the cabinet door frame 3; the circuit board mounting cover 8 is rotatably disposed on the circuit board mounting base 10; the circuit board mounting cover 8 is provided with a first positioning clamping block 11, a second positioning clamping block 12, and a mounting through hole 13 for wires to pass through; the circuit board mounting base 10 includes a circuit board mounting base body 14, a first limiting hole 15, a second limiting hole 16, and an isolation plate 17 for supporting the circuit board 6, the first limiting hole 15 and the second limiting hole 16 being respectively disposed on the circuit board mounting base 10. The circuit board mounting base body 14 is located on both sides of the base body 14; the isolation plate 17 is disposed on the circuit board card mounting base body 14 between the first limiting hole 15 and the second limiting hole 16; the first positioning clamping block 11 and the second positioning clamping block 12 are movably disposed on both sides of the circuit board card mounting cover 8, and both the first positioning clamping block 11 and the second positioning clamping block 12 are provided with positioning protrusions 18. When the circuit board card mounting cover 8 is disposed on the circuit board card mounting base 10, after the first positioning clamping block 11 and the second positioning clamping block 12 on the circuit board card mounting cover 8 are pressed together, the positioning protrusions 18 on the first positioning clamping block 11 and the second positioning clamping block 12 are respectively engaged in the circuit board mounting base body 14. On the first limiting hole 15 and the second limiting hole 16 of the circuit board mounting base body 14, one end of the return spring 9 is connected to the circuit board mounting base body 14, and the other end abuts against the first positioning clamping block 11 and the second positioning clamping block 12 respectively. Since the circuit board mounting cover 8 is provided with the first positioning clamping block 11 and the second positioning clamping block 12, and the circuit board mounting cover 8 is provided with the first positioning clamping block 11, the second positioning clamping block 12 and the mounting through hole 13 for wires to pass through, when the circuit board mounting cover 8 is locked on the circuit board mounting base body 14, the first positioning clamping block 11 and the second positioning clamping block 12 are abutted against each other. The positioning protrusion 18 engages with the first limiting hole 15 and the second limiting hole 16 on the circuit board mounting base body 14. When the positioning protrusion 18 on the circuit board mounting cover 8 separates from the first limiting hole 15 and the second limiting hole 16 on the circuit board mounting base body 14, the circuit board mounting cover 8 separates from the circuit board mounting base body 14. The reset spring 9 can then release the positioning protrusion 18 on the first positioning clamping block 11 and the second positioning clamping block 12, thereby better separating the positioning protrusion 18 on the first positioning clamping block 11 and the second positioning clamping block 12 from the first limiting hole 15 and the second limiting hole 16.

[0043] In this utility model, a limiting groove 19 is provided on the circuit board mounting base body 14, and a reset spring 9 is disposed in the limiting groove 19. The limiting groove 19 can limit the compression deformation of the reset spring 9, which is simple and practical. The circuit board mounting base body 14 and the limiting groove 19 are integrated structures. The integrated circuit board mounting base body 14 and the limiting groove 19 can effectively simplify the structure of the circuit board mounting base 7. In practical applications, heat dissipation holes 20 can be provided on the isolation plate 17, the circuit board mounting cover 8 and the circuit board mounting base 10. The heat dissipation holes 20 facilitate heat dissipation of the circuit board 6.

[0044] In addition, a press-to-unlock device 21 can be provided on the circuit board mounting cover 8. The press-to-unlock device 21 allows for easy unlocking of the circuit board mounting cover 8, enabling its opening and facilitating maintenance personnel to inspect the circuit boards inside the circuit board mounting base body 14. In this invention, the press-to-unlock device 21 includes a presser 22, a press spring 23, and an unlocking post 24. The presser 22 is pressable on the circuit board mounting cover 8 via the press spring 23. The unlocking post 24 is located at the bottom of the presser 22. When the presser 22 is pressed down, the unlocking post 24 presses against the positioning protrusions 18 of the first positioning clamping block 11 and the second positioning clamping block 12, causing the positioning protrusions 18 on the first positioning clamping block 11 and the second positioning clamping block 12 to engage with the first limiting hole 15 and the second limiting hole 16 on the circuit board mounting base body 14. Hole 16 is separated. During use, maintenance personnel press the presser 22, which can press down the press spring 23, causing the unlocking post 24 to press down the positioning protrusion 18 of the first positioning clamping block 11 and the second positioning clamping block 12. This causes the positioning protrusion 18 to separate from the first limiting hole 15 and the second limiting hole 16 on the circuit board card mounting base body 14, thereby realizing the opening control of the circuit board card mounting cover 8. In practical applications, as needed, a device for verification and identification during unlocking can be added to the press unlocker 21, or unlocking can be achieved by a key. These are all solutions that are easy for those skilled in the art to conceive of. In this utility model, the display screen 4 is a transparent screen. Since the display screen 4 is a transparent screen, the purchaser can interact with the human-computer interaction through the transparent screen and also observe the situation of the items in the cabinet through the transparent screen, which is simple and convenient.

[0045] Example

[0046] In this embodiment, one or more circuit board cards are provided on the inner side of the cabinet door frame, and the width of the circuit board cards is smaller than the width of the cabinet door frame. Therefore, compared with the prior art, this utility model evenly arranges one or more circuit board cards connected to the display screen on the cabinet door frame near the pivot side. Thus, it does not affect the buyer's viewing of the products inside the cabinet, while also effectively reducing the thickness and overall weight of the cabinet door frame, enhancing the buyer's user experience, and reducing the occurrence of problems such as sagging and poor opening and closing of the cabinet door frame due to long-term use.

[0047] In addition, in practical applications, a circuit board mounting bracket can be provided on the inside of the cabinet door frame, and the circuit board can be placed in the circuit board mounting bracket. The circuit board mounting bracket can protect the circuit board.
