Description

Technical Field

[0001] This application relates to the field of intelligent self-service equipment technology, and in particular to a host device and a self-service device. Background Technology

[0002] Self-service equipment is a smart device that uses interactive devices such as touchpads or keyboards to fulfill user needs, providing consumers with convenient services such as registration, appointments, access to services, office work, shopping, and payments. Existing self-service equipment typically features a coin acceptor or a QR code payment device on the front, as well as input / output devices such as buttons or panels. These devices extend across the front cabinet panel of the self-service equipment, with some located on the surface for user operation and others extending into the cabinet to connect to the host computer.

[0003] However, to prevent these devices from being disassembled by non-maintenance personnel, their mounting structures are all located inside the self-service equipment. Therefore, installing these devices requires one person to support the payment or interactive device from the front of the cabinet panel, while another person installs the device onto the cabinet panel from the back. This necessitates multiple personnel for the installation, disassembly, and maintenance of the self-service equipment, resulting in low work efficiency. Utility Model Content

[0004] In view of this, this application provides a self-service device that can be easily installed and disassembled, which can improve the problem of multiple human resources required when maintaining self-service devices.

[0005] Embodiments of this application provide a host device mounted on a server rack panel. The server rack panel has a front side, a back side, and mounting holes penetrating the front side and the back side. The host device includes a host unit and a back clip. The host unit has a first mounting surface that adheres to the front side, and the first mounting surface has a supporting structure that abuts against the inner peripheral wall of the mounting hole. The back clip adheres to the back side and is detachably connected to the host unit, and the supporting structure is housed within the back clip.

[0006] By incorporating a support structure and a back clip, maintenance personnel can install the main unit onto the rack panel. First, the support structure abuts against the inner wall of the mounting hole, allowing the main unit to hang on the front of the panel, with a portion of the main unit exposed. Then, the maintenance personnel move to the back of the rack panel and attach the back clip to the exposed portion of the main unit. This clamps the main unit and the back clip, securing it to both the front and back of the rack panel. This method of hanging the main unit on the mounting hole eliminates the need for another maintenance personnel to support the main unit from the front when installing it from behind the rack panel. Consequently, the entire installation process can be completed by a single maintenance worker, significantly improving the efficiency of main unit installation, removal, and maintenance.

[0007] In at least one embodiment, the host includes a main body and a mounting portion, the mounting portion being located on the side of the main body facing the back clip, the first mounting surface being disposed on the main body, and the mounting portion extending at least partially into the mounting hole and being detachably connected to the back clip.

[0008] By setting up a main body and a mounting part, the first mounting surface of the main body fits tightly against the front of the rack panel, allowing the mounting part to penetrate deep into the mounting hole and extend to the back of the rack panel, making it convenient for the back clip to be attached to the mounting part on the back of the rack panel.

[0009] In at least one embodiment, the supporting structure includes a fixing portion and a supporting portion. The fixing portion is connected to the first mounting surface. The supporting portion is connected to the fixing portion, and the supporting portion is angled relative to the fixing portion, the supporting portion being used to abut against the inner peripheral wall.

[0010] The design of the support part allows it to combine with the first mounting surface to form a structure that restricts the movement of the host in two directions. When the first mounting surface is attached to the front of the cabinet panel, the support part abuts against the inner peripheral wall of the mounting hole, so that the inner peripheral wall provides upward support to the host, thus preventing the host from falling.

[0011] In at least one embodiment, the support structure further includes a blocking portion connected to one end of the support portion away from the fixing portion, the blocking portion being angled to the support portion and extending to the back side, for preventing the host from making horizontal displacement.

[0012] The design of the blocking part ensures that if the host computer slides down due to its center of gravity shifting away from the first mounting surface when it is hung on the inner wall of the mounting hole, the blocking part can hold it against the back of the rack panel, preventing the host computer from easily falling off and improving stability during mounting. Furthermore, even if the host computer is slightly tilted when the blocking part is against the back of the rack panel, maintenance personnel can still adjust the position of the mounting part from behind the rack panel, thus not affecting the continued installation of the back clip.

[0013] In at least one embodiment, the supporting structure and the blocking part are elastic structures.

[0014] By adopting an elastic structure for the support structure and the blocking part, the host can be partially displaced when it is hung on the inner wall of the mounting hole through the support structure and the blocking part. This makes it easier for maintenance personnel to fine-tune the relative position of the host and the back clip when installing the back panel behind the cabinet panel, without being stuck by the support structure and the blocking part, thus improving installation efficiency.

[0015] In at least one embodiment, the first mounting surface is provided with a plurality of connection holes, and the support structure is detachably connected to any of the connection holes.

[0016] By providing multiple connection holes, if maintenance personnel encounter a discrepancy between the actual and designed mounting hole shapes, they can disassemble the support structure and adjust its relative position to the host based on the inner wall position of the actual mounting hole. Understandably, server rack panels have various standard mounting hole specifications, allowing for the design of multiple connection hole positions to accommodate different mounting hole sizes. Furthermore, if the support structure is damaged during production or transportation, it can be replaced individually, saving material costs.

[0017] In at least one embodiment, the first mounting surface is provided with a first magnetic element, and the cabinet panel is provided with a second magnetic element or the cabinet panel is made of a magnetic material.

[0018] By using a magnetic attachment method, the first mounting surface is more securely attached to the rack panel and will not easily fall off.

[0019] In at least one embodiment, the back clip has a second mounting surface, which is disposed around the mounting hole and abuts against the back surface.

[0020] By setting the second mounting surface to surround the mounting hole, the entire inner circumferential wall of the mounting hole is clamped when the host and back clamp are clamped onto the cabinet panel, thus improving the firmness of the connection between the host and the back clamp.

[0021] In at least one embodiment, the second mounting surface is provided with a clearance groove for accommodating the supporting structure.

[0022] By incorporating clearance slots, the supporting structure or obstruction can be accommodated when the back clip is connected to the host, thus preventing interference with the second mounting surface's contact with the back of the cabinet panel. This enhances the secure connection between the back clip and the host.

[0023] In at least one embodiment, the second mounting surface is symmetrically arranged, and a plurality of the clearance grooves are provided on the second mounting surface, some of the clearance grooves being used to accommodate the supporting structure.

[0024] The symmetrical clearance groove design allows the back clip to accommodate the support structure whether it is installed upright or upside down on the main unit, eliminating the need for maintenance personnel to specifically align the clearance groove with the support structure and saving maintenance personnel's time.

[0025] In another embodiment of this application, a self-service device is also provided. The self-service device includes a cabinet and any one of the aforementioned main unit devices. The cabinet has a cabinet panel, which has a front, a back, and mounting holes penetrating the front and back. The main unit is mounted in the mounting holes.

[0026] By installing a support structure on the main unit of the self-service equipment, maintenance can be achieved by first hanging the main unit on the mounting holes during installation, or by preventing the main unit from falling off during disassembly. This allows for installation and disassembly of the main unit to be completed by a single person.

[0027] The aforementioned host unit employs a support structure and a back clip design. When installing the host unit on the rack panel, maintenance personnel can first use the support structure to abut against the inner wall of the mounting hole, allowing the host to be hung on the front of the rack panel, with part of the host exposed. Then, the maintenance personnel walk around to the back of the rack panel and attach the back clip to the exposed part of the host in the mounting hole. This clamps the host and back clip, securing the host to both the front and back of the rack panel. By using the support structure to hang the host in the mounting hole, maintenance personnel can install the host from behind the rack panel without needing another person to support it from the front. Therefore, the entire installation operation can be completed by only one maintenance person, improving the efficiency of host unit installation, disassembly, and maintenance.

[0035] To further illustrate the technical means and effects adopted by this application to achieve the intended purpose, the following description, in conjunction with the accompanying drawings and embodiments, is provided. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0036] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

[0037] It should be noted that when an element is considered "connected to" or "located on" another element, it can be directly connected to the other element or may have an intervening element. In this application, unless otherwise explicitly specified and limited, the terms "installed," "connected," and "fixed," etc., 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; and they can refer to the internal communication between two elements. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0038] The terms "first," "second," etc., are used only to distinguish different objects and should not be construed as indicating or implying relative importance or implicitly specifying the number, specific order, or primary / secondary relationship of the indicated technical features. In the description of the embodiments of this application, "multiple" means two or more, unless otherwise explicitly defined. The descriptions of shapes such as length, thickness, and width in the embodiments of this application are merely illustrative and should not constitute any absolute limitation on this application. Some embodiments of this application will be described in detail below with reference to the accompanying drawings. Unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0039] Self-service equipment is a smart device that uses interactive devices such as touchpads or keyboards to fulfill user needs, providing consumers with convenient services such as registration, appointments, office work, shopping, and payment. Existing self-service equipment typically features a coin acceptor or a QR code payment device on the front, as well as input / output devices such as buttons or panels. These devices extend across the front cabinet panel of the self-service equipment, with some located on the surface for user operation and others extending into the cabinet to connect to the host computer.

[0040] However, to prevent these devices from being disassembled by non-maintenance personnel, their mounting structures are all located inside the self-service equipment. Therefore, installing these devices requires one person to support the payment or interactive device from the front of the cabinet panel, while another person installs the device onto the cabinet panel from the back. This necessitates multiple personnel for the installation, disassembly, and maintenance of the self-service equipment, resulting in low work efficiency.

[0041] Please see Figure 1 and Figure 2 One embodiment of this application provides a host device 200, which is installed on a cabinet panel 1. The cabinet panel 1 has a front 101, a back 102 and a mounting hole 11 that passes through the front 101 and the back 102. The host device 200 includes a host 2 and a back clip 3.

[0042] Please see Figure 2 and Figure 3 The main unit 2 has a first mounting surface 211 that is close to the front side 101. The first mounting surface 211 is provided with a support structure 23, which abuts against the inner peripheral wall 111 of the mounting hole 11. The back clip 3 is close to the back side 102 and is detachably connected to the main unit 2. The support structure 23 is housed in the back clip 3.

[0043] The cabinet panel 1 of the self-service equipment can typically be opened like a door to expose the internal structure of the cabinet. These cabinets usually have user-accessible devices mounted on the cabinet panel 1. Mounting holes 11 are pre-drilled to accommodate these devices. The cabinet panel 1 is made of sheet metal, making the edges of the mounting holes 11 thin. The main unit 2 is a user-operated device. The side of the main unit 2 that contacts the cabinet panel 1 is the first mounting surface 211, which has a support structure 23. The support structure 23 mates with the edge of the mounting hole 11, allowing the main unit 200 to be hung on the inner peripheral wall 111 of the mounting hole 11.

[0044] The edge of the mounting hole 11 can be bent inwards towards the inside of the cabinet, making the area of ​​the inner peripheral wall 111 larger and the support structure 23 more effective. It also reduces the sharpness of the mounting hole edge, reducing the probability of injury to maintenance personnel.

[0045] A host 2 is provided with two support structures 23 located on both sides of the first mounting surface 211 in the horizontal direction, so that the two support structures 23 are hung as far as possible on the outermost sides of the inner peripheral wall 111 of the mounting hole 11, so that the host 2 is more balanced and stable when mounted.

[0046] Self-service equipment encompasses various fields, such as ticket vending machines in subways, charging stations at gas stations, queuing machines in hospitals or banks, vending machines and beverage dispensers in stores, parcel or takeout storage machines, water dispensers, and coffee machines. These self-service devices all feature a cabinet, typically housing various types of main unit devices 200, such as barcode scanners, coin acceptors, card readers, keypads, displays, touchscreens, and queuing machines. All of these devices can be designed with the aforementioned support structure 23, allowing a single maintenance personnel to install or remove multiple different types of main unit devices.

[0047] By setting up the support structure 23 and the back clip 3, when the maintenance personnel install the host device 200 on the cabinet panel 1, they can first use the support structure 23 of the host 2 to abut against the inner peripheral wall 111 of the mounting hole 11 so that the host 2 can be hung on the front 101 of the cabinet panel 1, with part of the host 2 structure exposed in the mounting hole 11. Then, the maintenance personnel go around to the back of the cabinet panel 1 and connect the back clip 3 to the part of the host 2 exposed in the mounting hole 11, so that the host 2 and the back clip 3 cooperate to clamp the front 101 and the back 102 of the cabinet panel 1, thereby fixing the host device 200 on the cabinet panel 1.

[0048] By using the support structure 23 to hang the main unit 2 on the mounting hole 11, maintenance personnel can install the main unit 2 from behind the cabinet panel 1 without another maintenance personnel supporting the main unit 200 from the front 101 of the cabinet panel 1. Thus, the entire installation operation can be completed by only one maintenance personnel, improving the efficiency of installation, disassembly, and maintenance of the self-service equipment.

[0049] Please see Figure 1 , Figure 2 , Figure 4 In some embodiments, the host 2 includes a main body 21 and a mounting part 22. The mounting part 22 is located on the side of the main body 21 facing the back clip 3. A first mounting surface 211 is provided on the main body 21. The mounting part 22 extends at least partially into the mounting hole 11 and is detachably connected to the back clip 3.

[0050] The main body 21 has a housing and functional components. The functional components inside the housing include a circuit board and components such as a keyboard, buttons, and a display screen that are connected to the circuit board and can be operated by the user.

[0051] A flat first mounting surface 211 is formed on one side of the outer shell. The area of ​​the first mounting surface 211 can cover the area of ​​the mounting hole 11. A mounting part 22 is protruding on the first mounting surface 211. The mounting part 22 is provided with multiple interfaces 221. Through the interfaces 221 and cables, the functional components of the main body 21 can be connected to the circuit structure of the cabinet. The area of ​​the mounting part 22 is smaller than that of the first mounting part, and the thickness of the mounting part 22 exceeds the thickness of the sheet metal of the cabinet panel 1.

[0052] The dimensions of the mounting part 22 are adapted to the dimensions of the mounting hole 11. The mounting hole 11 is square, and the shape of the mounting part 22 is cuboid. The area of ​​the mounting hole 11 is utilized as much as possible to facilitate the arrangement of the interface 221 on the mounting part 22 and to facilitate the extension of the cable connected to the interface 221 into the cabinet.

[0053] By setting the main body 21 and the mounting part 22, the first mounting surface 211 of the main body 21 is closely attached to the front side 101 of the cabinet panel 1, so that the mounting part 22 can penetrate into the mounting hole 11 and extend to the back side 102 of the cabinet panel 1, making it convenient for the back clip 3 to be connected to the mounting part 22 on the back side 102 of the cabinet panel 1.

[0054] Please see Figure 3 , Figure 4 In some embodiments, the host device 200 includes a variety of hosts 2, each host 2 having a different mounting part 22, and the back clip 3 is detachably connected to any mounting part 22.

[0055] A self-service device typically has multiple host devices 2, including but not limited to barcode scanners, card readers, coin acceptors, touch screens, and displays. Different host devices 2 have different sizes and shapes, which in turn result in different numbers and types of connectors, leading to variations in the external dimensions of the mounting parts 22 of different host devices 2.

[0056] The mounting section 22 has threaded holes 24 facing inwards from the cabinet. The back clip 3 has through holes 33, and screws 34 pass through the through holes 33 to connect to the threaded holes 24 of the mounting section 22, allowing the back clip 3 to connect to the mounting section 22. Each mounting section 22 has four threaded holes 24, located at its four corners. The positions of the threaded holes 24 vary depending on the size of the mounting section 22. The back clip 3 has multiple through holes 33, forming multiple sets of fitting threaded holes 24, allowing the same back clip 3 to be used with various mounting sections 22.

[0057] When locking, the main unit 200 uses only one set of threaded holes 24 and some through holes 33, leaving some redundant through holes 33. These redundant through holes 33 can be used to organize the cables of the rear connection interface 221. For example, cables can be passed through the through holes 33 to organize their routing, or cables can be bundled to the back clip using cable ties in conjunction with the through holes 33. This makes the wiring of the entire main unit 200 neat and tidy, facilitating maintenance personnel to manage the wiring during subsequent equipment maintenance and improving work efficiency.

[0058] By using a universal back clip 3, a single self-service device no longer needs multiple back clips 3 to accommodate various host devices 200. Understandably, a self-service device includes various host devices 200, such as barcode scanners, card readers, coin acceptors, or touchscreen displays. Different types of host devices 200 have different sizes; using a universal back clip 3 facilitates installation by maintenance personnel, improving work efficiency. Furthermore, producing a single self-service device eliminates the need to design multiple different back clips 3, increasing production efficiency and saving material costs.

[0059] Please see Figure 5 In some embodiments, the support structure 23 includes a fixing part 231 and a supporting part 232. The fixing part 231 is connected to the first mounting surface 31. The supporting part 232 is connected to the fixing part 231, and the supporting part 232 is set at an angle to the fixing part 231. The supporting part 232 is used to abut against the inner peripheral wall 111.

[0060] The design of the support part 232 allows the support part 232 and the first mounting surface 211 to form a structure that restricts the movement of the host 2 in two directions. When the first mounting surface 211 is attached to the front of the cabinet panel 1, the support part 232 abuts against the inner peripheral wall 111 of the mounting hole 11, so that the inner peripheral wall 111 provides an upward support force to the host 2, thereby preventing the host 2 from falling.

[0061] Please see Figure 5 In some embodiments, the support structure 23 further includes a blocking part 233, which is connected to the end of the support part 232 away from the fixing part 231. The blocking part 233 is set at an angle to the support part 232 and extends to the back side 102 to prevent the host 2 from making horizontal displacement.

[0062] The design of the blocking part 233 ensures that when the host 2 is hung on the inner peripheral wall 111 of the mounting hole 11, if the host 2 slides down due to its center of gravity moving away from the first mounting surface 211, the blocking part 233 can abut against the back 102 of the rack panel 1, preventing the host 2 from easily falling off and improving stability during mounting. Furthermore, when the blocking part 233 abuts against the back 102 of the rack panel 1, even if the host 2 is slightly tilted, maintenance personnel can still adjust the position of the mounting part 22 from the back 102 of the rack panel 1, thus not affecting the continued installation of the back clip 3 from behind.

[0063] Please see Figure 4 In some embodiments, the supporting structure 23 is an elastic structure.

[0064] By adopting an elastic structure for the support structure 23 and the blocking part 233, the host 2 can be partially displaced when it is hung on the inner peripheral wall 111 of the mounting hole 11 through the support structure 23 and the blocking part 233. This makes it easier for maintenance personnel to fine-tune the relative position of the host 2 and the back clip 3 when installing the back panel behind the cabinet panel 1, without being stuck by the support structure 23 and the blocking part 233, thus improving installation efficiency.

[0065] Please see Figure 4 In some embodiments, the first mounting surface 211 is provided with a plurality of connection holes (not shown in the figure), and the support structure 23 is detachably connected to any of the connection holes.

[0066] The mounting holes 11 of some cabinets are not precisely machined. When replacing the host 2, the original mounting holes 11 and the current host 2 may not be fully compatible due to the different models of the host 2. Consequently, when the original support structure 23 is hung on the inner peripheral wall 111 of the mounting hole 11, the mounting part 22 is not fully exposed through the mounting hole 11 to the back of the cabinet panel 102. Therefore, the position of the support structure 23 can be changed to adjust the relative position of the mounting part 22 and the mounting hole 11.

[0067] By providing a plurality of connection holes, if the maintenance personnel encounter a situation where the shape of the actual installation hole 11 is inconsistent with the designed installation hole 11, the supporting structure 23 can be disassembled to adjust the relative position of the supporting structure 23 and the host 2 according to the position of the inner peripheral wall 111 of the actual installation hole 11. It can be understood that there are various standard specifications for the installation holes 111 on the cabinet panel 1, and the positions of the plurality of connection holes can be designed according to different standard specifications to facilitate the host 2 to adapt to installation holes 11 of different specifications. If the supporting structure 23 is damaged during production or transportation, the supporting structure 23 can also be replaced separately, saving material costs.

[0068] Please refer to Figure 2 , in some embodiments, the first mounting surface 211 is provided with a first magnetic member (not shown in the figure), and the cabinet panel 1 is provided with a second magnetic member or the cabinet panel 1 is made of a magnetic material.

[0069] The first mounting surface 211 is embedded with a magnet. The material of the cabinet panel 1 is usually a ferromagnetic material such as stainless steel or galvanized steel. Therefore, the first mounting surface 211 can be magnetically attracted to the front surface 101 of the cabinet panel 1 to reduce the pressure that the supporting structure 23 needs to bear. Or magnets are provided at corresponding positions on the back surface 102 of the cabinet panel 1, so that the magnet on the first mounting surface 211 and the magnet on the cabinet panel 1 interact with each other, and then the host 2 is magnetically attracted to the cabinet panel 1.

[0070] By providing a magnetic attraction method, the first mounting surface 211 is more firmly connected to the cabinet panel 1 and will not easily fall off.

[0071] Please refer to Figure 2 , Figure 3 , in some embodiments, the back clip 3 is provided with a second mounting surface 31, and the second mounting surface 31 is arranged around the installation hole 11 and is in close contact with the back surface 102.

[0072] The back clip 3 is a frame structure, and the second mounting surface 31 on the back clip 3 is in the shape of a Chinese character 'hui'. When viewed from the front projection of the cabinet panel 1, the projection of the second mounting surface 31 surrounds the installation hole 11. The hollow part in the back clip 3 is used to avoid the cables of the connection joints.

[0073] By setting the second mounting surface 31 in a shape surrounding the installation hole 11, when the host 2 and the back clip 3 clamp the cabinet panel 1, the entire position where the inner peripheral wall 111 of the installation hole 11 is located is clamped, improving the firmness of the connection between the host 2 and the back clip 3.

[0074] Please refer to Figure 2 , in some embodiments, the second mounting surface 31 is provided with an avoidance groove 32, and the avoidance groove 32 is used to accommodate the supporting structure 23.

[0075] The depth and width of the clearance groove 32 are sufficient to accommodate the supporting structure 23, ensuring that the supporting structure 23 does not press against the back clip 3 within the clearance groove 32 when the second mounting surface 31 is tightly against the back of the cabinet panel 102. A notch 321 is formed at the outer edge of the frame of the back clip 3 in the clearance groove 32, allowing the blocking part 233 to move through the notch 321 within the clearance groove 32. This allows maintenance personnel to adjust the position of the back clip 3 to align it with the mounting part 22 without interfering with the movement of the back clip 3.

[0076] By providing the clearance groove 32, when the back clip 3 is connected to the host 2, the supporting structure 23 or the blocking part 233 can be accommodated by the clearance groove 32, thus preventing interference with the second mounting surface 31's close contact with the back of the cabinet panel 1 102. This improves the firmness of the back clip 3's connection to the host 2.

[0077] Please see Figure 2 In some embodiments, the second mounting surface 31 is symmetrically arranged, and a plurality of clearance grooves 32 are provided on the second mounting surface 31, some of which are used to accommodate the supporting structure 23.

[0078] The clamp is set as a frame, with the center line of the back clamp 3 on both sides as the axis of symmetry, and the clearance groove 32 is symmetrically set on the other two sides according to the axis of symmetry.

[0079] The symmetrical clearance groove 32 design allows the back clip 3 to accommodate the support structure 23 whether it is installed upright or upside down on the main unit 2, so that maintenance personnel do not need to specifically connect the clearance groove 32 to the support structure 23, saving maintenance personnel's working time.

[0080] Furthermore, those skilled in the art should recognize that the above embodiments are merely illustrative of this application and are not intended to limit this application. Any appropriate changes and variations made to the above embodiments within the essential spirit and scope of this application fall within the scope of this application's disclosure.
