Description

Technical Field

[0001] This utility model relates to the fields of POS machine base connection structure and POS equipment structure, and in particular to a POS machine base connection device and POS equipment with adjustable adsorption force. Background Technology

[0002] As a financial payment device used daily by merchants, POS machines can be used either handheld or attached to a POS base and placed on a checkout counter. Generally, POS bases 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 results in a weaker bond between the POS machine and the base, making it susceptible to detachment and falls due to shaking or impacts. 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. Therefore, improving the flexibility and ease of adjustment between the POS base and the POS machine is a research topic of significant practical importance. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide a POS machine base connection device and POS equipment with adjustable adsorption force that is simple in structure, convenient to switch, and has a compact design.

[0004] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0005] An adjustable adsorption POS machine base connection device includes a POS machine and a POS machine base. The upper surface of the POS machine base is provided with a receiving portion for accommodating the POS machine. The connection device includes a first component, a second component, and a moving mechanism. The first component is embedded in the back of the POS machine. The moving mechanism is disposed in the POS machine base and has an operating end and a moving end. The operating end is exposed on the outer surface of the POS machine base. The second component is connected to the moving end of the moving mechanism, and the moving mechanism drives the second component to move within the POS machine base.

[0006] When the POS machine is placed in the receiving part, the first component and the second component have a first state and a second state;

[0007] In the first state, the second component is opposite to the first component;

[0008] In the second state, the operating end of the moving mechanism is subjected to force, causing the second component to be moved by the moving end to a position that is misaligned with the first component;

[0009] One of the first component and the second component is a permanent magnet, and the other is an iron part that can be attracted by the permanent magnet, or both the first component and the second component are permanent magnets, and in the first state, their opposite magnetic poles are facing each other.

[0010] As one possible implementation, further, the first component of 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.

[0011] As one possible implementation, the accommodating part described in this solution is a concave structure adapted to the outer contour of the POS machine, and the bottom surface of the concave structure is an inclined structure.

[0012] As one possible implementation, further, the first component of this solution is a permanent magnet, and the second component is an iron piece that can be attracted by the permanent magnet;

[0013] or,

[0014] The first component is an iron piece that can be attracted by a permanent magnet, and the second component is a permanent magnet;

[0015] or,

[0016] Both the first and second components are permanent magnets, and in the first state, their opposite magnetic poles are facing each other.

[0017] As a preferred embodiment, the main body of the POS machine base in this solution is a shell structure, with an internal mounting cavity. The mounting cavity contains a boss facing the receiving portion, and the boss has a pair of opposing guide rails. The moving mechanism includes:

[0018] The connecting frame is slidably connected to a pair of guide rails on both sides and is set as the moving end of the moving mechanism. The second component is fixedly connected to the connecting frame. The connecting frame is also provided with an extension exposed on the outer surface of the POS machine base. The extension is set as an operating end. The connecting frame is moved on the guide rails by the force applied to the operating end. The housing structure of the POS machine base is also provided with a clearance groove corresponding to the extension for it to pass through.

[0019] As a preferred implementation, the connecting frame of this solution is provided with sliding grooves on both sides and is slidably connected to a pair of slide rails through the sliding grooves.

[0020] As a preferred embodiment, the extension of this solution preferably extends through one side or the bottom of the housing structure of the POS machine base, and the housing structure of the POS machine base is provided with a clearance groove corresponding to the extension for it to pass through.

[0021] As a preferred implementation method, this solution further includes a limiting member on the side of the guide rail that is separated from the guide rail, and the two sides of the connecting frame are provided with outward protrusions. The connecting frame is provided with a slotted structure corresponding to the outward protrusions to allow the outward protrusions to deform and retract under force.

[0022] In the first state, the protruding part is limited by the limiting member on one side. In the second state, the protruding part is deformed by the pushing force of the operating end and passes over the limiting member to release the limiting state.

[0023] As a preferred implementation method, preferably, in the first state of this solution, the extension portion serving as the operating end makes single-sided contact with and limits one end of the clearance groove.

[0024] As a preferred implementation method, the limiting member in this solution is preferably an I-shaped structure. In the first state, the protruding part is limited by one side of the limiting member, and the extension part serving as the operating end is limited by one side of the clearance groove.

[0025] In the second state, when the extension, which serves as the operating end, moves to the other end of the clearance groove, the extension is limited by contact on one side of the clearance groove, and at the same time, the protruding part is limited by contact on the other side of the limiting member.

[0026] Based on the above, this solution also provides a POS machine device, which includes the aforementioned adjustable adsorption force POS machine base connecting device.

[0027] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: The ingenuity of this solution lies in setting a first component and a second component on the POS machine and the POS machine base, and utilizing the magnetic attraction properties of the first component and the second component to improve the contact force between the POS machine base and the POS machine. When the POS machine is placed in the receiving part of the POS machine base, the first component and the second component can generate an auxiliary force to improve the placement stability of the POS machine. The moving mechanism set inside the POS machine base is connected to the second component, and the position of the second component is switched by the moving mechanism, so that the first component and the second component are in a first state or a second state of relative or misalignment. This makes it easy to adjust the contact force between the POS machine and the POS machine base, which facilitates the flexible use and fixation of the POS machine, and can take into account both free-access and fixed use scenarios.

[0041] 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.

[0042] Example 1

[0043] Combination Figures 1 to 9 As shown in one embodiment, this embodiment provides a POS machine base connection device with adjustable adsorption force, which includes a POS machine 100 and a POS machine base 200. The upper end surface of the POS machine base 200 is provided with a receiving part 201 for accommodating the POS machine 100. The connection device also includes a first component 300, a second component 400, and a moving mechanism 500.

[0044] In this solution, the first component 300 is embedded on the back of the POS machine 100. Specifically, the first component 300 is embedded in the back of the POS machine 100 and is not exposed on the surface of the POS machine 100. However, this solution is not limited to this and the first component 300 may also have part of its structure exposed on the surface of the POS machine 100.

[0045] In this solution, the accommodating part 201 is a concave structure adapted to the outer contour of the POS machine 100, and the bottom surface of the concave structure is an inclined structure.

[0046] The moving mechanism 500 described in this solution is disposed inside the POS machine base 200. It has an operating end 501 and a moving end. The operating end 501 is exposed on the outer surface of the POS machine base 200. The second component 400 is connected to the moving end of the moving mechanism 500, and the moving mechanism 500 drives the second component 400 to move inside the POS machine base 200.

[0047] When the POS machine 100 is placed in the accommodating part 201, the first component 300 and the second component 400 have a first state and a second state.

[0048] In the first state, the second component 400 is opposite to the first component 300;

[0049] In the second state, the operating end 501 of the moving mechanism 500 is subjected to force, causing the second component 400 to be moved by the moving end to a position that is misaligned with the first component 300.

[0050] In this solution, the first component 300 and the second component 400 can adopt a magnetic attraction structure to adjust and control the adsorption force of the POS machine 100 on the POS machine base 200. In this solution, one of the first component 300 and the second component 400 is a permanent magnet, and the other is an iron part that can be attracted by the permanent magnet. Alternatively, both the first component 300 and the second component 400 are permanent magnets, and in the first state, their opposite magnetic poles are opposite to each other.

[0051] As an example of a possible implementation, the first component 300 and the second component 400 of this solution can be implemented in one of the following combinations:

[0052] (1) In this solution, the first component 300 is a permanent magnet, and the second component 400 is an iron part that can be attracted by the permanent magnet;

[0053] (2) The first component 300 is an iron part that can be attracted by a permanent magnet, and the second component 400 is a permanent magnet;

[0054] (3) Both the first component 300 and the second component 400 are permanent magnets, and in the first state, their opposite magnetic poles are opposite to each other.

[0055] In this way, when the POS machine 100 is placed in the receiving part 201 of the POS machine base 200, the relative attraction between the first component 300 and the second component 400 can improve the placement stability of the POS machine and prevent the POS machine 100 from sliding out of the receiving part 201 and falling off due to shaking or slight collision.

[0056] When it is necessary to cancel the adsorption assistance, the first component 300 and the second component 400 can be misaligned by moving the operating end 501, thereby reducing the adsorption force and making it easier to pick up the POS machine 100.

[0057] As a preferred implementation method, the main body of the POS machine base 200 in this solution is a shell structure, which has an installation cavity 202 inside. The installation cavity 202 has a boss 210 facing the receiving part, and the boss 210 has a pair of guide rails 211 with opposite positions.

[0058] Based on the above structure, the moving mechanism 500 described in this solution includes:

[0059] The connecting frame 510 is slidably connected to a pair of guide rails 211 on both sides and is set as the moving end of the moving mechanism 500 (that is, the body of the connecting frame 510 is the movable moving end). The second component 300 is fixedly connected to the connecting frame 510. The connecting frame 510 is also provided with an extension exposed on the outer surface of the POS machine base 200. The extension is set as an operating end 501. The connecting frame 510 is moved on the guide rails 211 by the force applied to the operating end 501. The shell structure of the POS machine base 200 is also provided with a relief groove 203 for the extension to pass through.

[0060] In this solution, to prevent the connecting frame 510 from detaching from the slide rail 211, as a preferred implementation method, the connecting frame 510 is preferably provided with slide grooves 513 on both sides, and is slidably connected to a pair of slide rails 211 through the slide grooves 513.

[0061] In this embodiment, the extension protrudes from the bottom of the housing structure of the POS machine base 200, and the bottom of the housing structure of the POS machine base 200 is provided with a clearance groove 203 for the extension to pass through.

[0062] To avoid the connection frame 510 being too loose and causing an unreliable relative positional relationship between the first component 300 and the second component 400, as a preferred embodiment, this solution preferably provides a limiting member 220 on the side of the guide rail 211 that is separated from it. The connection frame 510 has protrusions 511 on both sides, and the connection frame 510 has a slotted structure 512 corresponding to the protrusions 511 for the protrusions 511 to deform and retract under force.

[0063] In this design, the limiting member 220 has an I-shaped structure.

[0064] In the first state, the protruding portion 511 is limited by the limiting member 220 on one side. At this time, the operating end 501 is just moved to one end of the relief groove 203, and is limited by the relief groove 203 in the other direction. That is, under the limitation at both ends, when no force greater than the deformation of the protruding portion 511 intervenes, the connecting frame 510 is in a temporary constrained and fixed state, which can be achieved by combining... Figure 4 , Figure 5 , Figure 6 The three images illustrate the current state of the connector 510.

[0065] In the second state, due to manual intervention, the operating end 501 is manually moved with a force greater than the deformation of the protruding part 511, causing it to be subjected to force along the other end of the relief groove 203. At this time, the protruding part 511 is deformed by the pushing force of the operating end 501 and passes over the limiting member 220, thus releasing the limiting state. At this time, no continuous constraint force is formed between the two sides of the I-shaped limiting member 220. Therefore, the connecting frame 510 can be moved relatively easily by the operating end 501, and its state is visible. Figure 9 As shown, when pushed further, the protruding part 511 will contact and constrain the other end of the limiting member 220. At this time, if a force greater than the deformation of the protruding part 511 is applied, the protruding part 511 can be deformed by the pushing force of the operating end 501 and pass over the other end of the limiting member 220. At this time, the operating end 501 just moves to the other end of the relief groove 203, which is limited by the relief groove 203 in the other direction. Therefore, the first component 300 and the second component 400 can be kept in a stable misaligned state (see reference). Figure 7 (The state shown).

[0066] In the above situation, the operator only needs to manually apply a force greater than the deformation of the protrusion 511 to push it, so that the first component 300 and the second component 400 can be restored to the first state.

[0067] Based on the above, the solution of this embodiment can be applied to POS machine equipment to flexibly realize the switching of the adsorption force between the POS machine and the POS machine base, so that the operator can move the POS machine freely or fix the POS machine on the POS machine base for fixed use.

[0068] This solution uses a moving mechanism 500 to switch the position of the second component 400, so that the first component 300 and the second component 400 are in a relative or misaligned first state or second state. This makes it easy to adjust the contact force between the POS machine 100 and the POS machine base 200, which facilitates the flexible use and fixation of the POS machine 100, and enables it to accommodate both free-access and fixed-use scenarios.

[0069] Example 2

[0070] Combination Figures 10 to 12 As shown in one embodiment, the scheme of this embodiment is largely the same as that of embodiment 1. The difference is that in this embodiment, the extension protrudes from one side of the housing structure of the POS machine base 200 and is set as the operation end 501. One side of the housing structure of the POS machine base 200 is provided with a clearance groove 203 for the extension to pass through.

[0071] The state changes of the operation terminal 501 in this embodiment when switching the first component and the second component are roughly the same as in Embodiment 1, so the changes in the coordination between the operation terminal 501 and the moving mechanism will not be described again.

[0072] The structural forms of other unmentioned reference numerals in this embodiment are roughly the same as those in Embodiment 1, and their structural details will not be described again here.

[0073] 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.
