Description
Technical Field
[0001] This utility model relates to the field of POS machine technology, and more specifically to a POS machine card swiping guide light. Background Technology
[0002] With the development of science and technology, POS machines (i.e., point-of-sale terminals) have become an indispensable financial tool in our lives. Especially when people use bank cards for purchases, POS machines are essential equipment for merchants. As a commonly used device in people's lives and widely adopted in the service industry, the optimization direction for POS machines is to make them more user-friendly and aesthetically pleasing, providing consumers with a better user experience. Existing POS machines generally have indicator lights to indicate the status of the POS machine and payment status. However, existing POS machine indicator lights have the following defects, resulting in poor indication effects: 1. A single indicator light is inconspicuous on the entire device; 2. Multiple indicator lights, due to differences in the light path, suffer from insufficient brightness and unevenness, affecting judgment. Utility Model Content
[0003] The purpose of this invention is to provide a POS machine card swiping guide light that has both good guidance and indication effects and uniform brightness.
[0004] To achieve the above objectives, the POS machine card swiping guide light provided by this utility model is assembled on the POS machine housing and includes a diffuser plate, a light guide component, and a light source. The diffuser plate is made of milky white PC diffuser plate, and there are several light-emitting columns on the diffuser plate, with the top surface of each light-emitting column being the light-emitting surface; The light guide is made of transparent PC material and assembled below the diffuser plate. One end face of the light guide is the light incident surface, and the bottom surface and at least one of the two sides of the light guide are serrated structures. The depth of the serrations increases as they move further away from the light incident surface. The light source is located beside the light-incident surface of the light guide.
[0005] Furthermore, light enters the light guide from its incident surface, is reflected by the sawtooth structure, exits from the top surface of the light guide, reaches the diffuser plate, and exits from the light emitting surface of the diffuser plate.
[0006] Furthermore, the bottom surface of the diffuser plate has a recessed portion corresponding to the bottom of each light column.
[0007] Furthermore, the shape of the recessed portion is consistent with that of the light-emitting column, but its size is smaller than that of the light-emitting column.
[0008] Furthermore, the light-emitting column is triangular in shape, and the light-emitting surface is triangular. The apex of the triangular light-emitting surface points in the direction of card swiping, and each aperture has the same shape as the light-emitting surface.
[0009] Furthermore, the light-emitting surface is an isosceles triangle with the apex pointing in the card-swiping direction, and there are three light-emitting columns, which are evenly distributed on the diffuser plate.
[0010] Furthermore, the bottom surface and one of the sides of the light guide have a serrated structure.
[0011] Furthermore, the top surface of the light guide is flat, and assembly parts are provided at both ends of the top surface of the light guide. The diffuser plate and the light guide are connected through the assembly parts.
[0012] Furthermore, in the sawtooth structure of the light guide, the spacing between each tooth is 0.4mm, and the tooth depth varies from 0.02mm to 0.12mm from the near light source end to the far light source end.
[0013] Furthermore, the POS machine housing has through holes corresponding to each light-emitting surface, and the shape of each through hole is consistent with that of the light-emitting surface.
[0014] With the above solution, the POS machine card-swiping guide light of this utility model has several light-emitting columns, so it can present the effect of multiple guide lights on the POS machine, and play a better guiding role; the diffuser plate is made of milky white PC diffuser plate, and the milky white material has a diffusion effect, which can make the light spot on the light-emitting surface more uniform and the visual effect better; the light guide component is made of transparent PC material and has a serrated structure. The light emitted by the light source can reach the light-emitting surface of the diffuser plate after being reflected in the serrated structure. When used with a side light source, since the depth of the serrations is greater the further away from the light-incident surface, the light from the side light source can be evenly distributed to three light guide columns at different distances from the light source, so that the brightness of each light-emitting surface is consistent, providing users with a better viewing experience.
[0015] Preferably, the light-emitting surface is triangular and points in the direction of card swiping, which can guide the user to swipe the card in the correct direction, making the POS machine more user-friendly.
[0016] Preferably, the bottom surface of the diffuser plate has a recessed portion corresponding to the bottom of each light-emitting column, which reduces the thickness of the light-emitting column portion and prevents shrinkage during the injection molding of the diffuser plate.

[0031] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.
[0032] This utility model provides a POS machine card swiping guide light for assembly on a POS machine housing 4, including a diffuser plate 1, a light guide 2, and a light source 3.
[0033] The diffuser plate 1 is made of milky white PC. The diffuser plate 1 has several light-emitting columns 11, with each light-emitting column 11 having a light-emitting surface 111 on its top surface. The milky white material in the diffuser plate 1 has a diffusion effect, making the light spot on the light-emitting surface 111 more uniform and improving the visual effect. Furthermore, by having several light-emitting columns 11 on the diffuser plate 1, it has multiple light-emitting surfaces 111, thus creating the effect of multiple guide lights on the POS machine, providing better guidance.
[0034] See Figures 1 to 4In one embodiment, the diffuser plate 1 is strip-shaped and has three triangular prism-shaped light-emitting columns 11 of the same height. These columns are evenly spaced on the diffuser plate 1, and the light-emitting surface 111 is triangular, with the apex pointing towards the card-swiping direction. This allows the light-emitting surface 111 of the POS machine's card-swiping guide light to guide the user to swipe in the correct direction, making the POS machine more user-friendly. Preferably, the light-emitting surface 111 is an isosceles triangle, with the apex pointing towards the card-swiping direction. The uniform height of the light-emitting columns 11 is designed to match the POS machine housing 4, resulting in a neat overall appearance after installation. Different heights can be used when using different POS machine models. The uniformity of the light-emitting column height has a negligible impact on the final light effect of the light-emitting surface 111.
[0035] For details, please refer to [link / reference]. Figure 2 , Figure 4 In this embodiment, a recessed portion 12 is provided at the bottom of each light-emitting column 11 on the bottom surface of the diffuser plate 1. The shape of the recessed portion 12 is consistent with that of the light-emitting column 11, and its size is smaller than that of the light-emitting column 11. The thickness of the light-emitting column 11 is reduced by the recessed portion 12, which avoids shrinkage during the injection molding of the diffuser plate 1 and also reduces the weight of the diffuser plate 1.
[0036] The light guide 2 is strip-shaped, with two end faces and a top surface, a bottom surface, and two side surfaces extending in the elongation direction. The light guide 2 is made of transparent PC material and is assembled below the diffuser plate 1. One end face of the light guide 2 is the light incident surface 21. The bottom surface and at least one of the two side surfaces of the light guide 3 are sawtooth structures 22. The tooth depth (tooth depth: refers to the depth of a single sawtooth, that is, the vertical distance from the top to the bottom of the sawtooth) of the sawtooth structure 22 is larger the further away from the light incident surface 21. That is, the distance between each tooth in the sawtooth structure 22 is consistent, but the teeth closer to the light source are flatter (smaller tooth depth), and the teeth further away from the light source are more convex (larger tooth depth).
[0037] The working principle of the above structure is to generate total internal reflection of light using the sawtooth structure 22. Specifically, each tooth on the sawtooth structure 22 can reflect light, thereby dividing the light entering the light guide 2 from the side into two directions: direction one: upward towards the diffuser plate 1, and direction two: in the light guide 2, away from the light source 3. The depth of the teeth controls the proportion of light distributed to different directions. The greater the tooth depth, the more light received by the tooth surface is distributed to direction one after reflection, that is, more light reaches the diffuser plate 1.
[0038] See Figure 12This is a schematic diagram illustrating the working principle of this embodiment, showing the distribution of light reaching the tooth surface by the sawtooth structure 22 at each position of the light-emitting column 11. The larger the arrow, the greater the proportion of light distributed. That is, on the side closer to the light source, the teeth with smaller tooth depths in the sawtooth structure 22 distribute a small portion of the arriving light to direction one, and most of the light to direction two. As the distance from the light source 3 gradually increases, the tooth depth gradually increases, and the proportion of light distributed to direction one by each tooth gradually increases, while the proportion distributed to direction two gradually decreases. Since the total light received by the teeth further away from the light source 3 gradually weakens, the proportion of light distributed to direction one gradually increases, which just makes the amount of light entering each light guide column 11 at different distances from the light source 3 approximately the same (see...). Figure 13 This ensures that the brightness of the three light guide surfaces 111 is consistent (see...). Figure 14 ).
[0039] In this embodiment, the bottom surface and one of its side surfaces of the light guide 2 are serrated structures 22. Since the light source 3 emits light uniformly in all directions, it will hit all surfaces of the light guide 2. Surfaces without serrated structures 22 have poor reflection effects, and the light reaching them will only concentrate near the light source 3, causing the light to not reach the diffuser plate 1 uniformly, affecting the brightness and brightness uniformity of the guide lamp. Therefore, the more surfaces of the light guide 2 with serrated structures 22, except for the top surface (which is the light-emitting surface of the light guide 2 and does not need to be reflected), the better the light collection and distribution effect.
[0040] The placement of the serrated structure 22 on the light guide 2, and the number of surfaces on which it should be located, is limited by the POS machine structure. In this embodiment, to fit the POS machine housing structure, the light guide 2 cannot have three surfaces (one bottom surface and two side surfaces) with the serrated structure 22. Therefore, setting the bottom surface and one side surface of the light guide 2 as the serrated structure 22 achieves the best effect. If only one surface is set as the serrated structure 22, or if the serrated structure 22 is placed on two side surfaces, although light distribution can be achieved, the final guide light effect is not as good as the solution in this embodiment. However, for different POS machine housing structures, the light guide 2 can also adopt different designs (the number of surfaces with the serrated structure 22, the placement of the serrated structure 22 on different surfaces, etc.) to achieve the best light distribution effect.
[0041] In the sawtooth structure 22 of the light guide 2, the spacing between each tooth is 0.4 mm, and the tooth depth varies from 0.02 mm to 0.12 mm from the near end to the far end of the light source (i.e., the tooth depth of the tooth closest to the light source 3 is 0.02 mm, and the tooth depth gradually increases as it moves away from the light source 3, with the tooth depth of the tooth furthest from the light source 3 being the largest, at 0.12 mm). In different instances, these parameters can have different values according to actual needs.
[0042] See Figures 5 to 8 In one embodiment, the light guide 2 is strip-shaped, and the top surface of the light guide 2 is flat. The angle between the serrated structure 22 on the side of the light guide 2 and the top surface of the light guide 2 can be obtained by adjusting and optimizing the optical software so that the light can reach the light-emitting surface 111 of the diffuser plate 1. In different embodiments, the angle can have different values.
[0043] Further reading Figure 10 , Figure 11 The light source 3 is located beside the light-incident surface 21 of the light guide 2. The top surface of the light guide 2 has assembly parts 23 at both ends, and the diffuser plate 1 is connected to the light guide 2 through the assembly parts 23. In the aforementioned structure, light enters the light guide 2 from the light-incident surface 21, is reflected by the sawtooth structure 22, exits the top surface of the light guide 2, reaches the diffuser plate 1, and exits from the light-exit surface 111 of the diffuser plate 1.
[0044] The light guide 2 is made of transparent PC material and has a sawtooth structure 22. The light emitted by the light source 3 can be reflected in the sawtooth structure 22 and reach the light-emitting surface 111 of the diffuser plate 1. When used with the side light source 3 (i.e., the light-incident surface 21 is located at one end of the light guide 2), since the depth of the sawtooth structure 22 increases as it moves away from the light-incident surface 21, the light from the side light source 3 can be evenly distributed to the three light guide pillars at different distances from the light source 3, so that the brightness of each light-emitting surface 111 is consistent (see...). Figure 12 This provides users with a better viewing experience.
[0045] Therefore, this utility model can provide a POS machine card swiping guide light with both good guiding and indicating effects and uniform brightness by utilizing the structure of the diffuser plate 1, the light guide 2, and the assembly structure between them and the light source 3.
[0046] See Figure 9 This is one embodiment of the present invention assembled in a POS machine. In this embodiment, the POS machine housing 4 has through holes 41 corresponding to each light-emitting surface 111, and each through hole 41 has the same shape as the light-emitting surface 111 (in this embodiment, three isosceles triangular through holes 41 are provided corresponding to each light-emitting surface 111). Figure 9 In the POS machine housing 4 shown, the part where the guide light is installed is inclined, so the light-emitting surface 111 is set as an inclined surface to fit the POS machine housing 4. Correspondingly, the top of the recessed part 12 can also be set as an inclined surface. In other embodiments, the tilt angle of the light-emitting surface 111 can be set to correspond to different POS machine housings 4 to fit different POS machine housings 4 and improve the visual aesthetic effect.
[0047] The above is merely one embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
