Abstract
Description
Technical Field
[0001] This utility model relates to the field of POS machine devices, and in particular to a sliding button mechanism and an adjustable suction force POS machine base connection device and POS equipment. Background Technology
[0002] As a financial payment device used daily by merchants, a POS machine can be used either as a handheld unit or attached to a POS base and placed on a checkout counter. POS bases typically come in two types: universal bases and locking bases. Universal bases are traditional charging bases where the POS machine can be freely removed. This design emphasizes convenience, but the flexible structure means the connection between the POS machine and the base is weaker, making it susceptible to detachment due to shaking or impact, potentially causing the machine to fall. Locking bases, on the other hand, fix the POS machine to the base and prevent it from being freely removed, serving as a desktop device. Because locking bases have an additional fixed interface compared to universal bases, they are generally only suitable for scenarios where the POS machine can be freely removed (i.e., used separately) or not, and cannot accommodate flexible or convenient switching between these two scenarios.
[0003] Although some POS machines with bases currently use more convenient switching structures between the POS machine body and the base, such as easy-to-open and close latches, claw structures, or expansion structures, these components are mostly made of pure plastic. While they have good reliability in the early stages of use, with long-term use, due to factors such as aging and cumulative deformation of the plastic, the fit of the plastic components deviates from the original design precision. This can lead to the locking and unlocking structure between the POS machine and the base becoming loose after long-term use, affecting the fit.
[0004] Therefore, improving the flexibility and ease of adjustment between the POS machine base and the POS machine is a research topic with significant practical implications. Summary of the Invention
[0005] In view of this, the purpose of this utility model is to propose a sliding button mechanism and a POS machine base connection device and POS equipment with adjustable adsorption force that are simple in structure, reliable in implementation and convenient in operation.
[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0007] A slider mechanism comprising:
[0008] The connecting frame is a plate-shaped iron structure with a movable groove that passes through it, and at least one side of the movable groove has a sliding groove.
[0009] A connecting plate is movably disposed on one end face of the connecting frame. A slider is provided on the end face opposite to the connecting frame, corresponding to the slide groove, and is slidably connected to the slide groove through the slider. A protrusion is provided on the side of the connecting plate away from the connecting frame, and the protrusion is set as the operating end.
[0010] The permanent magnet is a block-shaped structure that is fixed on the end face of the connecting plate and the connecting frame. The permanent magnet also passes through the movable groove of the connecting frame and is driven by the connecting plate to move between one of the opposite sides of the movable groove.
[0011] As one possible implementation, the movable groove in this solution has a rectangular structure; the sliding groove is a pair, and the pair of sliding grooves are arranged opposite to each other on both sides of the movable groove.
[0012] Based on the above, this solution also proposes an adjustable adsorption force POS machine base connecting device for connecting a POS machine. The device includes a POS machine base, the upper surface of which has a receiving portion for accommodating the POS machine. The connecting device also includes the aforementioned sliding button mechanism. The main body of the POS machine base is a shell structure with an internal mounting cavity. The sliding button mechanism is disposed within the mounting cavity, and the connecting frame is fixed within the mounting cavity. An clearance groove is provided on the end face of the POS machine base away from the receiving portion, and protrusions on the connecting plate are exposed in the clearance groove for manual operation.
[0013] The POS machine has a mating component on its back, which is a magnet or an iron component; when the POS machine is placed in the receiving part, the mating component and the permanent magnet have a first state and a second state.
[0014] In the first state, the permanent magnet is opposite to the mating component. When the mating component is a magnetic component, it has opposite magnetic poles to the permanent magnet.
[0015] In the second state, the protrusion is subjected to force, causing the connecting plate to move the permanent magnet to a position where it is misaligned with the mating part.
[0016] As a preferred implementation method, the mating component described in this solution is embedded in the back of the POS machine, and is not exposed on the surface of the POS machine or has part of its structure exposed on the surface of the POS machine.
[0017] As a preferred embodiment, the accommodating part of this solution is preferably a concave structure adapted to the outer contour of the POS machine, and the bottom surface of the concave structure is an inclined structure.
[0018] As a preferred embodiment, the mounting cavity of this solution is provided with a boss facing the receiving portion. The connecting frame is fixedly connected to the boss, and an installation gap for mounting the connecting plate is formed between the boss and the connecting frame. The connecting plate is slidably disposed in the installation gap, and the slider on the connecting plate is slidably connected to the sliding groove on the connecting frame. The clearance groove is provided on the boss, and the protrusion portion of the connecting plate passes into the clearance groove.
[0019] As a preferred embodiment, the boss in this solution is provided with a pair of guide rails positioned opposite each other, the pair of guide rails being positioned corresponding to the two sides of the connecting plate, and the two sides of the connecting plate being provided with mating parts that slide with the guide rails.
[0020] As a preferred implementation method, preferably, in the first state of this solution, the protrusion serving as the operating end makes single-sided contact with and limits one end of the clearance groove.
[0021] As a preferred implementation method, the protrusion of this solution is provided with a first limiting member at one end corresponding to the sliding direction of the connecting plate, and a second limiting member at the other end corresponding to the sliding direction of the connecting plate.
[0022] In the first state, the protrusion, which serves as the operating end, makes single-sided contact with one end of the clearance groove and limits its movement; at the same time, one end of the connecting plate makes single-sided contact with the first limiting member and limits its movement.
[0023] In the second state, when the protrusion, which serves as the operating end, moves to the other end of the clearance groove, the protrusion is limited by contact on one side of the clearance groove. At the same time, the other end of the connecting plate is limited by contact on one side of the second limiting member.
[0024] Based on the above, this solution also proposes a POS device, which includes a POS machine and the aforementioned adjustable adsorption force POS machine base connection device.
[0025] Compared with the prior art, the present invention has the following advantages by adopting the above technical solution: The ingenious solution uses a mating component on the back of the POS machine and a permanent magnet inside the POS machine base. The magnetic attraction state is changed by altering the relative position of the permanent magnet and the mating component, thus ensuring a stable placement of the POS machine on the receiving part of the POS machine base and facilitating its removal. Furthermore, by attaching the permanent magnet to the sliding mechanism and placing it in the mounting cavity of the POS machine base, the first and second states of the permanent magnet and the mating component on the POS machine are switched by changing the sliding engagement state of the connecting frame and connecting plate of the sliding mechanism. This not only makes implementation convenient and compact, but also facilitates installation. The attraction force generated between the permanent magnet and the iron connecting frame increases the positional stability of the sliding mechanism, preventing loosening even after long-term use. Additionally, the metal plate-like connecting frame can be reused as a counterweight for the POS machine base, further improving the stability of the device. Attached Figure Description

[0036] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are only for illustrating the present invention and do not limit the scope of the present invention. Similarly, the following embodiments are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.
[0037] Combination Figures 1 to 9 As shown in one embodiment, this solution provides an adjustable suction force POS machine base connection device for connecting a POS machine 100. It includes a POS machine base 200 and a sliding button mechanism 300. The upper surface of the POS machine base 200 is provided with a receiving portion 221 for accommodating the POS machine 100. The sliding button mechanism 300 includes:
[0038] The connecting frame 310 is a plate-shaped iron structure with a movable groove 311 that runs through it. At least one side of the movable groove 311 is provided with a sliding groove 312. In this solution, the movable groove 311 is a rectangular structure. The sliding grooves 312 are a pair, and the pair of sliding grooves 312 are arranged opposite to each other on both sides of the movable groove 311.
[0039] A connecting plate 320 is movably disposed on one end face of the connecting frame 310. A slider 321 is provided on the end face opposite to the connecting frame 310 corresponding to the slide groove 312, and the slider 321 is slidably connected to the slide groove 312. A protrusion 322 is provided on the side of the connecting plate 320 away from the connecting frame 310. The protrusion 322 is an operating end, specifically used for manual operation by the operator.
[0040] The permanent magnet 330 is a block structure, which is fixed on the end face of the connecting plate 320 and the connecting frame 310. The permanent magnet 330 also passes through the movable groove 311 of the connecting frame 310. When the operator manually moves the protrusion 322 at the operating end, the connecting plate 320 drives the permanent magnet 330 to move between one of the opposite sides of the movable groove 311.
[0041] In this design, the connecting plate 320 is provided with a groove 323 to accommodate the permanent magnet 330.
[0042] In this solution, the main body of the POS machine base 200 is a shell structure, which includes a first shell 210 and a second shell 220. The first shell 210 and the second shell 220 together form the main body of the POS machine base 200, and an installation cavity 230 is provided inside. The sliding button mechanism 300 is disposed in the installation cavity 230. Specifically, the connecting frame 310 is fixed in the installation cavity 230. An avoidance groove 211 is provided on the end face of the POS machine base 200 away from the receiving part 221. The protrusion 322 on the connecting plate 320 is exposed in the avoidance groove 211 for manual operation.
[0043] In this preferred embodiment, the mounting cavity 230 is provided with a boss 240 facing the receiving portion. The connecting frame 310 is fixedly connected to the boss 240, and an installation gap for mounting the connecting plate 320 is formed between the boss 240 and the connecting frame 310. The connecting plate 320 is slidably disposed in the installation gap, and the slider 321 on the connecting plate 320 is slidably connected to the sliding groove 312 on the connecting frame 310. The clearance groove 211 is provided on the boss 240, and the protrusion 322 on the connecting plate 320 partially penetrates into the clearance groove 211.
[0044] exist Figures 1 to 6 Based on the structure shown, the focus is on combining Figures 7 to 9 As shown in one example, based on the above structure, the POS machine 100 of this solution has a mating part 101 on its back side. The mating part 101 is a magnetic part or an iron part. When the POS machine 100 is placed in the receiving part 221, the mating part 101 and the permanent magnet 330 have a first state and a second state.
[0045] In the first state, the permanent magnet 330 is opposite to the mating component 101. When the mating component 101 is a magnetic component, its magnetic poles are opposite to those of the permanent magnet 330 (reference). Figure 8 );
[0046] In the second state, the protrusion 322 is subjected to force, causing the connecting plate 320 to move the permanent magnet 330 to a position where it is misaligned with the mating part 101 (see reference). Figure 9 ).
[0047] As a preferred embodiment, the mating component 101 described in this solution is preferably embedded in the back of the POS machine 100, and is not exposed on the surface of the POS machine 100 or has a portion of its structure exposed on the surface of the POS machine 100.
[0048] In order to facilitate the placement of the POS machine and prevent it from slipping, as a preferred implementation method, the accommodating part 221 of this solution is preferably a concave structure that conforms to the outer contour of the POS machine 100, and the bottom surface of the concave structure is an inclined structure.
[0049] To improve the sliding reliability and accuracy of the connecting plate 320, as a preferred embodiment, the boss 240 of this solution is provided with a pair of guide rails 241 with opposite positions. The pair of guide rails 241 correspond to the two sides of the connecting plate 320. The two sides of the connecting plate 320 are provided with mating parts 240 that slide with the guide rails 241. In this solution, the mating part 240 is an L-shaped bent structure, and its bent side slides and positions with the guide rail 241.
[0050] To improve the accuracy of operator feedback, preferably, in the first state of this solution, the protrusion 322, serving as the operating end, is in single-sided contact with one end of the clearance groove 211 for limiting. That is, when the protrusion 322 is moved, it moves to one end of the clearance groove 211 and comes into contact with it, thus completing the first state. At this time, the permanent magnet 330 is directly opposite the mating part 101 placed on the POS machine 100 in the receiving part 221. In this embodiment, the contour of the movable groove 311 of the connecting frame 310 can be set to adapt to the contour of the clearance groove 211. Since the connecting frame 310 is a metal structure, in the first state, when the permanent magnet 330 approaches the movable slot 311 side of the connecting frame 310, it attracts the metal structure on the movable slot 311 side of the connecting frame 310. The movement of the permanent magnet 330 from far to near will increase the magnetic attraction between the permanent magnet 330 and the metal structure on the movable slot 311 side, generating a certain force feedback, providing a certain response for the operator's manual operation, so that the operator can quickly know whether the operation is in place, and the magnetic attraction will also further improve the stability of the permanent magnet 330 in maintaining the first state.
[0051] When switching from the first state to the second state, since the permanent magnet 330 is attracted to the metal structure on one side of the movable groove 311 of the connecting frame 310, the operator will feel a certain "damping" feedback when operating manually. The resistance of the protrusion 322 of the sliding mechanism 330 during operation (i.e., when the permanent magnet 330 slides with the connecting frame 320) will change with the position of the permanent magnet 330, generating a gradual resistance, which can effectively improve the operating feel of the sliding mechanism 330. When the first and second states reach their limits, the attraction between the permanent magnet 330 and the metal structure on the side of the connecting frame 310 reaches its maximum, and the sliding mechanism is in a stable state.
[0052] To improve the reliability of switching between the first and second states, as a preferred implementation method, the boss 240 in this embodiment is provided with a first limiting member 242 at one end corresponding to the sliding direction of the connecting plate 320. In this embodiment, the first limiting member 242 is a limiting plate. In the first state, one side of the connecting plate 320 is close to the limiting plate (first limiting member 242). The other end of the boss 240 corresponding to the sliding direction of the connecting plate 320 is provided with a second limiting member 243. In this embodiment, the second limiting member 243 can be reused as a connecting post (located on the boss 240) that is screwed between the first housing 210 and the second housing 220. This method can improve the simplification of the device structure while also taking into account functional reuse. Correspondingly, the other side of the connecting plate 320 is provided with a U-shaped limiting groove 324 that cooperates with the second limiting member 243.
[0053] Based on the above structure, in the first state, the protrusion 322, which serves as the operating end, makes unilateral contact with and limits one end of the clearance groove 211, while at the same time, one end of the connecting plate 320 makes unilateral contact with and limits the first limiting member 232.
[0054] In the second state, when the protrusion 322, which serves as the operating end, moves to the other end of the clearance groove 211, the protrusion 322 is limited by contact on one side of the clearance groove 211. At the same time, the other end of the connecting plate 320 is limited by contact on one side of the second limiting member 243.
[0055] Based on the above, the adjustable adsorption force POS machine base connection device of this solution can be applied in POS equipment to realize the flexible switching of the cooperation state between POS machine 100 and POS machine base 200, so as to realize the transformation of handheld use or fixed use scenario of POS machine 100.
[0056] The above description is only a part of the embodiments of this utility model, and does not limit the scope of protection of this utility model. Any equivalent device or equivalent process transformation made based on the content of this utility model specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this utility model.
