DETAILED DESCRIPTION

[0038] The technical solutions in the utility model will be described clearly and completely below with reference to the drawings in the utility model.

[0039] Embodiment One: The utility model provides a novel LCD display terminal integrated taxi fare meter, aims at improving the information display definition, operation convenience and the stability and safety of overall structure of taxi fare meter. The following is the detailed description of the meter:

[0040] The fare meter main part 100 as the core of whole equipment, integrated multiple function modules and components to meet various demands in the process of taxi operation. The fare meter shell 110 as the carrier of these components, not only provides protection, but also ensures the structural integrity of the whole equipment.

[0041] Inside the fare meter shell 110, display screen body 111 and control module are arranged. The display screen body 111 adopts high-resolution liquid crystal display technology, so that the information display is more clear and delicate. The display screen is carefully divided into multiple display areas, including the pricing area, the function area, the status area and the auxiliary information area. The pricing area is used to display the current pricing information in real time, such as driving mileage, driving time, unit price and total cost, etc. The function area displays specific function information such as double journey status, inspection status, calibration status, etc. The status area displays the printer status, whether the meter is pricing or not, and other key states. The auxiliary information area is used to display additional information such as IC card balance.

[0042] The control module as the "brain" of the fare meter, is responsible for automatically calculating the fare according to the driving mileage, driving time and waiting time, and presenting these information to the passengers and drivers through the display screen body 111. In addition, the control module is also responsible for receiving instructions from other components (such as control buttons 112) and performing corresponding operations.

[0043] The control buttons 112 are ingeniously arranged at the frame of the display screen body 111, which not only improves the convenience of operation, but also avoids the blocking of the buttons to the display screen. These buttons can be used to perform various specific operations, such as starting the meter, selecting the metering mode, viewing the history, etc.

[0044] In order to ensure the continuous and stable operation of the meter, we also open a power interface 113 on one side of the meter shell 110, and equipped with a matching connector 114. In this way, the driver can easily provide power to the entire meter through an external power supply, avoiding the interruption of metering due to insufficient power.

[0045] The mounting back clip 115 serves as a connecting component between the meter and the internal mounting structure of the taxi, and plays a role in fixing the entire meter. In order to ensure the safety and stability of the meter, we set a lead seal 116 on the edge where the mounting back clip 115 meets the meter housing 110. This design can effectively prevent unauthorized disassembly. Once the meter is disassembled without authorization, the lead seal 116 will be broken or removed, leaving obvious traces, so that the disassembly can be easily detected.

[0046] In summary, Example One provides a new type of liquid crystal display terminal integrated taxi meter with clear structure and perfect function. This meter not only improves the clarity of information display and the convenience of operation, but also enhances safety and stability through designs such as lead seals.

[0047] Example Two:

[0048] Based on Example One, Example Two makes further improvements and optimizations to improve the installation convenience, heat dissipation effect, and overall stability and durability of the meter. Here is a detailed description of Example Two:

[0049] Compared with Example One, the main difference of Example Two is the design of the mounting back clip 115. In Example Two, we install a rubber pad 117 on the inside of the mounting back clip 115 where it meets the meter housing 110. This rubber pad not only serves as a non-slip function to prevent the meter from slipping or shifting during installation, but also prevents damage to the outer surface of the meter housing during installation. In addition, the rubber pad has a certain elasticity, which can to some extent alleviate the vibration caused by road bumps and protect the internal electronic components of the meter from damage.

[0050] To further improve the heat dissipation effect, we also open through slots 128 on the mounting back clip 115. These through slots can effectively reduce the contact area between the mounting back clip and the meter housing, increase air flow, and thus improve the heat dissipation efficiency of the internal components of the meter. This is of great significance to ensure the stable operation of the meter in high temperature environments.

[0051] In Example Two, we also innovatively designed the structure of the mounting back clip 115, making it a quick disassembly structure. This structure includes two parts, the movable clamp seat 118 and the fixed clamp seat 119. The fixed clamp seat is installed with a lead screw 120 through a threaded groove, and the top end of the lead screw is connected to the movable clamp seat through a bearing. When installing or disassembling the meter, you only need to rotate the hand wheel 123 at the bottom of the lead screw, which will drive the movable clamp seat to rise and fall, thus achieving quick disassembly of the meter. This design not only improves the installation efficiency, but also facilitates the later maintenance and replacement.

[0052] To ensure that the hand wheel will not accidentally rotate when it is not needed to rotate, we also add a anti-deflection mechanism in the quick disassembly structure. The mechanism includes ring-shaped socket 124, plug 125, limiting slot 126 and limiting cone 127 components. The ring-shaped socket is fixed on the outer surface of the hand wheel, and the plug is inserted into the ring-shaped socket through the insertion slot. The bottom end of the fixed clamp seat is provided with a limiting slot, and the top end of the plug is provided with a limiting cone which is matched with the limiting slot. When the plug is inserted into the ring-shaped socket, the limiting cone will be clamped into the limiting slot, thereby locking the position of the hand wheel and preventing it from deflecting.

[0053] In addition, example two also adds a damping assembly to improve the stability and durability of the meter on bumpy roads. The damping assembly includes a connecting base 129, a buffer spring column 130, and a base 131. The connecting base is connected to the mounting back clip through a connecting block, and the buffer spring column is connected between the connecting base and the base. These buffer spring columns are composed of dampers and springs, which can absorb a certain amount of vibration energy generated by road bumps, protecting the internal electronic components of the meter from damage.

[0054] Finally, in order to prevent the power interface and connector from loosening during use, we also designed a anti-loosening mechanism. The mechanism includes a clamping slot 133, a sliding slot 134, a sliding block 135, a return spring 136 and a clamping rod 137. The clamping slot is provided at the top end of the connector, and the clamping rod is inserted into the clamping slot to fix the connector. The sliding block is fixedly connected with the clamping rod and slides in the sliding slot. The return spring is connected between the top end of the sliding slot and the top end of the sliding block, which provides a downward force on the clamping rod to keep the connector tight.

[0055] In summary, example two has made a number of improvements and optimizations based on example one, not only improving the installation convenience and heat dissipation effect of the meter, but also enhancing the stability and durability of the overall structure through the addition of damping components and anti-loosening mechanisms and other designs. These improvements make the new type of LCD display terminal integrated taxi meter more in line with the actual needs of taxi operation, providing more convenient, safe and stable metering services for drivers and passengers.

[0056] Finally, it should be noted that in the description of the present application, it should be noted that unless otherwise specified and limited, the terms "mounting", "connecting", "connecting" should be broadly understood, which can be mechanical connection or electrical connection, or the internal connection of two elements, or direct connection. "Up", "down", "left", "right" and the like are only used to indicate the relative positional relationship, and when the absolute position of the described object changes, the relative positional relationship may change;

[0057] Secondly: the utility model discloses the embodiment in the drawing, only relate to the structure with the embodiment of the present disclosure, other structures can refer to the usual design, under the condition of not conflict, the same embodiment and different embodiments of the utility model can be combined with each other.

[0058] Finally: the above is only the preferred embodiment of the utility model and is not used for limiting the utility model, and any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
