Description

Technical Field

[0001] This application relates to the technical field of taximeters, and particularly to an integrated printing taximeter for taxis. Background Art

[0002] A taximeter is a core device in taxi operations. Its main function is to calculate the transportation fees for passengers by measuring the distance and time traveled by the vehicle. This device is of great significance in the taxi industry, ensuring not only the accuracy and reasonableness of billing but also providing a basis for fair transactions between passengers and drivers. Historically, taximeters have evolved from mechanical to electronic. Early taximeters were mostly mechanical in structure with relatively simple functions, mainly used for measuring the driving mileage and waiting time and displaying the fees. With the progress of technology, electronic taximeters have gradually replaced mechanical ones, featuring higher measurement accuracy and anti-cheating functions, and being able to display information such as trip fees, mileage, and time in real time. In recent years, the functions of taximeters have been continuously enriched, gradually developing towards intelligence and multi-functionality. For example, some new taximeters integrate a GPS positioning system, capable of recording driving trajectories and supporting remote monitoring and data analysis. At the same time, to prevent fraud and tampering, taximeters are usually equipped with a security module to ensure the security and integrity of data.

[0003] There is a common problem of insufficient integration of functional components in taxi intelligent IoT terminal devices. Their pricing module and ticket output unit are in a split architecture, objectively causing redundant equipment layout, large occupied space, and bringing many inconveniences to drivers' operations. At the same time, there are obvious defects in the ticket cutting process of traditional thermal printing solutions. The inaccurate positioning accuracy of the dotted line indentation results in rough ticket edges and skewed tearing lines, and it is extremely easy to produce serrated damage when tearing the voucher, which not only directly affects the professionalism of the service experience but also poses a risk of incomplete retention of ticket information. Summary of the Invention

[0004] This system provides an integrated printing taximeter for taxis, and the specific implementation is as follows:

[0005] An integrated printing taximeter for taxis, comprising:

[0006] A base, with a display screen integrated at the front end and a printing paper outlet bin integrated at the rear end, and a top shell is hinged to the printing paper outlet bin;

[0007] An unlocking key acting on the printing paper outlet bin is provided on the top shell, and a lead seal is built into the printing paper outlet bin;

[0008] The paper output bin of the printer is provided with a paper output structure, which includes a unwind roller and a printing part. An invoice paper is wound around the unwind roller. The display screen and the printer paper output bin are both integrated on the base, and a mechanical button is also provided on the base. The display screen and the paper output structure are both electrically connected to the mechanical button.

[0009] Based on the above technical solutions, the printer paper output bin and the display screen are integrated into one, which significantly reduces the volume of the meter device compared with the traditional solution. At the same time, due to the smaller volume of the device, the operating space of the driver's cab is significantly improved, providing a more spacious and convenient operating environment for taxi drivers and effectively optimizing the space layout of the driver's cab.

[0010] Preferably, the paper output structure further includes a driving roller arranged in parallel with the unwind roller, and a cutting component is arranged around the side of the driving roller; the cutting component includes a butting roller with the same rotation center as the driving roller, a cutter is rotatably arranged on the side of the butting roller, and the cutter is connected to a cylinder.

[0011] Based on the above technical solutions, in order to optimize the invoice printing and cutting process, a cutter and a butting roller are added. During the invoice printing process, when it has not entered the cutting stage, the cutter is in the retracted state, and at this time the butting roller starts to play a role. By adjusting its own position and pressure, the butting roller can control the tension of the invoice paper, ensuring that the invoice paper always maintains a stable and flat state during the conveying process, laying a good foundation for the subsequent cutting work; when the invoice cutting operation is required, the cylinder is used as the power source to provide driving force for the cutter, and the invoice paper is initially cut by the blade; the invoice paper can pass between the driving roller and the butting roller, at this time a clamping effect is generated on the invoice paper, and the outgoing paper is more accurate. At this time, the cutter is above the invoice paper and cuts from top to bottom; the invoice paper can also pass around the periphery of the butting roller, at this time the cutter is below the invoice paper and cuts from bottom to top.

[0012] Preferably, the outer end of the cutting component is connected to a telescopic driving component, and the output part of the telescopic driving component is coaxially arranged with the unwind roller.

[0013] Preferably, the telescopic driving component includes a C-shaped seat, a rotating cylinder is rotatably arranged inside the C-shaped seat, and a gear set is arranged outside the C-shaped seat; the output end of the gear set is connected to a lead screw rotatably sleeved inside the rotating cylinder, the input end of the gear set is connected to a first motor, the rotating cylinder is connected to a second motor through a worm gear structure, and the rotating cylinder and the lead screw form a lead screw structure, and its output end is connected to the cutting component through a shaft displacement component.

[0014] Preferably, the shaft displacement component includes a first vertical plate and a second vertical plate, which are connected by a connecting rod; the second vertical plate is axially slidably sleeved on the rotating cylinder, and the second vertical plate is threadedly connected to the lead screw. A worm gear is arranged on the outer peripheral surface of the rotating cylinder, which meshes with the worm on the C-shaped seat.

[0015] Preferably, the cutting edge portion of the cutter is provided in an inclined surface shape, and the edge length on the side close to the telescopic drive assembly is greater than the edge length on the side far from the telescopic drive assembly.

[0016] Preferably, the abutting roller is rotatably connected to the first vertical plate, a cam is provided on one side of the cutter as a whole in an L shape, and a cylinder is provided between the eccentric end of the cam and the first vertical plate.

[0017] Based on the above technical solutions, by setting the telescopic drive assembly, the position of the cutting assembly is controlled. During the paper feeding stage of the invoice paper, the telescopic drive assembly is started, driving the cutting assembly to move axially away outward, so as to avoid the paper feeding process and prevent the cutting assembly from hindering the paper feeding; and when entering the pre-cutting link, the telescopic drive assembly acts again, driving the cutting assembly to intervene axially inward, so that the cutting assembly accurately reaches the predetermined position.

[0018] Preferably, a linkage assembly is provided between the printing part and the unwinding roller; the linkage assembly includes a vertical moving plate slidably connected to the vertical limit buckle, a horizontal moving plate slidably connected to the horizontal limit buckle, and a turning plate rotatably connected to the hinge seat. One end of the turning plate is connected to the printing part through the vertical moving plate, and the other end is connected to the driving roller through the connecting plate and the horizontal moving plate.

[0019] Based on the above technical solutions, a linkage assembly is provided between the printing part and the unwinding roller, which can coordinate the synchronous operation of the printing part and the unwinding roller before and after the pre-cutting of the invoice paper; the printing part and the unwinding roller cooperate with each other to apply a suitable acting force to the invoice paper, adjust the tension of the invoice paper, and the stable and appropriate tension greatly improves the accuracy of subsequent operations such as paper feeding and cutting.

[0020] Preferably, a proximity switch acting on the first vertical plate is provided at the end of the lead screw.

[0021] In summary, the present application includes the following beneficial technical effects:

[0022] 1. In the present invention, by integrating the printing paper outlet bin and the display screen of the taximeter into one body, the volume of the device is reduced by 45% compared with the traditional solution, and the operating space on the driver's platform is increased by 60%;

[0023] 2. In the present invention, by installing a cutter and an abutting roller, the cutter is retracted before cutting, and the tension of the invoice paper is first adjusted by the abutting roller, and then the cutter is turned out by the cylinder drive to realize the preliminary cutting of the invoice paper, improving the neatness of the cross section when the subsequent invoice paper is torn;

[0024] 3. In the present invention, by setting the telescopic drive assembly, the axial distance avoidance of the cutting assembly during the paper feeding process of the invoice paper is realized, and at the same time, the axial intervention of the cutting assembly during the pre-cutting process is realized;

[0025] 4.
