Abstract
Description
Technical Field
[0001] This application relates to the field of mobile payment terminal technology, specifically a mobile payment terminal capable of printing vouchers. Background Technology
[0002] A mobile payment terminal, or POS machine for short, is a portable electronic device that integrates multiple payment functions. It enables fast and secure transaction processing through wireless communication technology, allowing users to complete consumption, transfers, and bill payments through bank cards, mobile payment applications, e-wallets, and other methods. It is widely used in retail, catering, transportation, medical and other scenarios, and features high convenience and fast transaction speed, making it an indispensable payment tool in modern business activities.
[0003] An existing patent (publication number: CN220105775U) discloses a mobile payment terminal capable of printing vouchers, including a terminal body. The outer wall of the terminal body is provided with buttons, and a protective shell is provided on one side of the terminal body. A display screen is located above the buttons, a barcode scanner is located above the terminal body, and a printer base is located above the barcode scanner. A disassembly button is located on the outer wall of the printer base, and a paper roll is located on one side of the printer base. This utility model, by setting up a barcode scanner, printer base, paper roll, buttons, a processor, and a display screen, allows the mobile payment terminal to print vouchers. When using the mobile payment terminal, information is input via the buttons or a card is inserted, the display screen shows the barcode information, the payment terminal scans the barcode via the barcode scanner, and after processing by the processor, the paper roll begins printing payment vouchers. The printed vouchers are printed from the outlet on the printer base, thus providing a voucher printing function and increasing the practicality of the mobile payment terminal.
[0004] However, in the above solutions, it was found that in actual use, mobile payment terminals require the input of payment passwords and other information. However, existing mobile payment terminals only protect the control panel from dust with a protective shell, which cannot effectively cover the control panel during use. This makes it easy for users to leak their passwords, posing a security risk. Utility Model Content
[0005] To address the shortcomings of existing technologies, this application provides a mobile payment terminal with printable vouchers. This terminal not only provides dust and protection for the control panel but also obscures its position, allowing the user to view the control panel only from their perspective. This also prevents password leakage. This solution addresses the problem that existing technologies only provide dust protection for the control panel with a protective shell, which does not effectively obscure the control panel during use, leading to easy password leakage for users.
[0006] To achieve the above objectives, this application provides the following technical solution: A mobile payment terminal capable of printing vouchers, comprising a terminal body and a protective cover one. A control panel is provided on the upper surface of the terminal body, and a printing module is provided on the right side of the terminal body. Rotary shafts are fixedly connected to both the front and back of the terminal body. The outer surface of each rotating shaft is rotatably connected to the inner wall of the protective cover one. Anti-slip damping blocks are fixedly connected to both the front and back of the protective cover one. A protective cover two is slidably connected to the outer surface of the protective cover one. Two magnetic strips one are fixedly connected to the bottom surface of the protective cover two. Magnetic strips two are fixedly connected to both the front and back of the terminal body. The bottom surface of each magnetic strip one is attracted to the upper surface of the corresponding magnetic strip two. A micro motor is fixedly installed on the front of the terminal body. A worm gear is fixedly connected to the output shaft of the micro motor. A worm wheel meshes with the outer surface of the worm gear, and the inner wall of the worm wheel is fixedly connected to the outer surface of the protective cover one.
[0007] To achieve dust protection for the control panel and prevent password leakage when the operator uses the terminal, a printing module is installed on the right side of the terminal body. This module can print vouchers instantly. Anti-slip damping blocks are placed on the surface of protective cover one and contact protective cover two. The sliding of protective cover two against protective cover one allows the cover to open. The magnetic strips one and two then adhere to the cover, securing it above the control panel and thus protecting it from dust. When needed, a micro motor rotates the worm gear, which in turn rotates through the connection between the worm and the worm wheel. The worm wheel is fixed to the first protective cover, allowing both the first and second protective covers to rotate at the pivot point. When raised to a certain angle, the protective covers obscure the control panel, ensuring that the operator can only view the panel from their own perspective, preventing password leakage. Anti-slip damping blocks between the first and second protective covers prevent relative sliding when no force is applied to the second protective cover.
[0008] Furthermore, a limit cover is rotatably mounted on the outer surface of the printing module, and printing paper is placed inside the printing module.
[0009] The above solution involves placing a limiting cover on the surface of the printing module and configuring it as a rotatable connection. By opening and closing the limiting cover, the printing module can be opened, and printing paper can be placed inside the printing module. After the limiting cover is opened, it is convenient to take out and put in the printing paper, making it easy to replace the printing paper.
[0010] Furthermore, the anti-slip damping block is made of rubber.
[0011] The above solution uses rubber as the material for the anti-slip damping block to ensure that it has sufficient anti-slip performance and durability. The anti-slip damping block can increase the friction between the first protective cover and the second protective cover, so that the second protective cover will not move when not affected by external forces.
[0012] Furthermore, a limiting frame is slidably connected to the inner wall of the protective cover, and a mounting plate is fixedly connected to the bottom surface of the limiting frame.
[0013] The above scheme involves installing the limiting frame on the inner wall of the protective cover and setting it as a sliding connection to achieve the limiting effect of the limiting frame. The mounting plate is installed on the bottom surface of the limiting frame and fixed between them. The mounting plate can slide up and down by sliding the limiting frame.
[0014] Furthermore, a pin is fixedly connected to the upper surface of the mounting plate, and the outer surface of the pin is slidably connected to the inner wall of the first protective cover and the second protective cover.
[0015] With the above solution, a pin is set on the upper surface of the mounting plate, and the pin is connected to the corresponding through holes on the first and second protective covers. When the second protective cover is moved, the pin is connected to the through hole, which can limit the second protective cover to the surface of the first protective cover, thus realizing the folding of the protective cover.
[0016] Furthermore, two springs are fixedly installed on the upper surface of the mounting plate, and the top of each spring is fixedly connected to the bottom surface of the protective cover.
[0017] The above solution involves installing a spring on the upper surface of the mounting plate and connecting the other end of the spring to the bottom surface of the first protective cover. The spring can tighten the mounting plate, ensuring that the pin is always connected to the through hole on the surface of the first protective cover, thus preventing the first and second protective covers from coming loose after sliding and folding.
[0018] Furthermore, a card slot is provided on the left side of the terminal body, and a limiting shell is fixedly installed on both the front and back of the terminal body.
[0019] The above solution places the card slot on the left side of the terminal body, making it easy for operators to insert cards into the terminal body. Limiting shells are set on the front and back of the terminal body, and the opening position of the limiting shells can limit the rotation angle of the protective cover.
[0020] Furthermore, the inner wall of each of the limiting shells is fixedly connected to the end of the corresponding rotating shaft, and the inner wall of one of the limiting shells is fixedly connected to the front of the micro motor.
[0021] By connecting the inner wall of the limiting shell to the rotating shaft in the above scheme, it can be fixed to prevent the limiting shell from falling off and improve the stability of the limiting shell. Connecting the micro motor to the corresponding limiting shell can protect the micro motor and ensure that the micro motor can work normally.
[0022] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0023] This mobile payment terminal, capable of printing vouchers, incorporates components such as a first protective cover, a second protective cover, a worm gear, and a worm wheel. A printing module enables instant voucher printing. The first and second protective covers, along with magnetic strips, cover the control panel, providing dust protection. During use, a micro-motor rotates the worm gear, which in turn rotates the first protective cover. This raises both protective covers at an angle, obscuring the control panel and preventing password leakage, as the panel is only visible from the user's perspective. To position the terminal in a fixed location, the second protective cover is pushed, and a limiting bracket is pressed, moving a pin. Once the second protective cover is in position, the limiting bracket is released, and a spring causes the pin to lock it in place. The worm gear and worm wheel then allow the protective cover to flip behind the terminal, providing support and facilitating adjustment of the support angle. Attached Figure Description

Detailed Implementation
[0032] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.
[0033] Please see Figure 4 , Figure 5 and Figure 6 This embodiment of a mobile payment terminal capable of printing vouchers includes a terminal body 1 and a protective cover 7. A control panel 2 is provided on the upper surface of the terminal body 1, and a printing module 3 is provided on the right side of the terminal body 1. Rotating shafts 6 are fixedly connected to both the front and back of the terminal body 1.

Anti-slip damping blocks 9 are fixedly connected to both the front and back of the protective cover 7. A protective cover 8 is slidably connected to the outer surface of the protective cover 7. Two magnetic strips 10 are fixedly connected to the bottom surface of the protective cover 8. Magnetic strips 11 are fixedly connected to both the front and back of the terminal body 1. The bottom surface of each magnetic strip 10 is attracted to the upper surface of the corresponding magnetic strip 11. A micro motor 12 is fixedly installed on the front of the terminal body 1. A worm gear 13 is fixedly connected to the output shaft of the micro motor 12. A worm wheel 14 meshes with the outer surface of the worm gear 13, and the inner wall of the worm wheel 14 is fixedly connected to the outer surface of the protective cover 7.
[0034] Please see Figure 1 and Figure 3 A limiting cover 4 is rotatably mounted on the outer surface of the printing module 3. Printing paper 5 is placed inside the printing module 3. The limiting cover 4 is set on the surface of the printing module 3 and is configured for rotational connection. The printing module 3 can be opened by opening and closing the limiting cover 4. Printing paper 5 is placed inside the printing module 3. After the limiting cover 4 is opened, it is convenient to take out and put in the printing paper 5, which is convenient for replacing the printing paper 5.
[0035] Please see Figure 5 and Figure 6The anti-slip damping block 9 is made of rubber. The use of rubber in the anti-slip damping block 9 ensures that the anti-slip damping block 9 has sufficient anti-slip performance and durability. The anti-slip damping block 9 can increase the friction between the protective cover 1 7 and the protective cover 2 8, so that the protective cover 2 8 will not move when not affected by external forces.
[0036] Please see Figure 5 The inner wall of the protective cover 7 is slidably connected to a limiting frame 15. The bottom surface of the limiting frame 15 is fixedly connected to an mounting plate 16. The limiting frame 15 is installed on the inner wall of the protective cover 7 and is set as a sliding connection to achieve the limiting effect of the limiting frame 15. The mounting plate 16 is installed on the bottom surface of the limiting frame 15 and is fixed between them. The mounting plate 16 can slide up and down by the up and down sliding of the limiting frame 15.
[0037] Please see Figure 5 A pin 17 is fixedly connected to the upper surface of the mounting plate 16. The outer surface of the pin 17 is slidably connected to the inner wall of the first protective cover 7 and the second protective cover 8. The pin 17 is set on the upper surface of the mounting plate 16 and connected to the corresponding through holes on the first protective cover 7 and the second protective cover 8. When the second protective cover 8 is moved, the pin 17 is connected to the through hole, which can limit the second protective cover 8 to the surface of the first protective cover 7, thereby realizing the folding of the protective cover.
[0038] Please see Figure 5 Two springs 18 are fixedly installed on the upper surface of the mounting plate 16. The top end of each spring 18 is fixedly connected to the bottom surface of the protective cover 7.

The card slot 20 is set on the left side of the terminal body 1, so that the operator can easily insert the card into the terminal body 1. The limiting shells 19 are set on the front and back of the terminal body 1. The opening position of the limiting shells 19 can limit the rotation angle of the protective cover 7.
[0040] Please see Figure 2 , Figure 3 and Figure 5The inner wall of each limiting shell 19 is fixedly connected to the end of the corresponding rotating shaft 6. The inner wall of one of the limiting shells 19 is fixedly connected to the front of the micro motor 12. Connecting the inner wall of the limiting shell 19 to the rotating shaft 6 and fixing it can prevent the limiting shell 19 from falling off and improve the stability of the limiting shell 19. Connecting the micro motor 12 to the corresponding limiting shell 19 can protect the micro motor 12 and ensure that the micro motor 12 can work normally.
[0041] This embodiment of a mobile payment terminal capable of printing vouchers includes components such as a protective cover 7, a protective cover 8, a worm gear 13, and a worm wheel 14. A printing module 3 enables instant voucher printing. The protective covers 7, 8, magnetic strips 10 and 11 cover the control panel 2, providing dust protection. In use, activating the micro motor 12 rotates the worm gear 13, causing the worm wheel 14 to rotate the protective cover 7. This raises the protective covers 7 and 8 at a certain angle, allowing for... The position of the control panel 2 is covered, so that the control panel 2 can only be viewed from the user's perspective during use, which can prevent password leakage. When the terminal body 1 needs to be placed in a fixed position for use, push the protective cover 2 8, and the pin 17 will move by pressing the limit bracket 15. When the protective cover 2 8 is in place, release the limit bracket 15, and the pin 17 will limit the protective cover 2 8 by the spring 18. Then, through the connection of the worm gear 13 and the worm wheel 14, the protective cover will be flipped to the rear of the terminal body 1, which can support the terminal body 1, making it easy to use and easy to adjust the support angle.
[0042] It should be noted that by setting the anti-slip damping block 9, the friction between the protective cover 7 and the protective cover 8 can be increased, so that the protective cover 8 can stop moving without the action of external force. The printing module 3 adopts thermal printing technology.
[0043] The working principle of the above embodiments is as follows:
[0044] When in use, the printing module 3 can print vouchers instantly. When not in use, the protective cover 7, the protective cover 8, the magnetic strip 10, and the magnetic strip 11 can cover the control panel 2 to prevent dust and protect it. When the user enters a password on the terminal body 1, the micro motor 12 is activated, causing the worm gear 13 to rotate, which in turn causes the worm wheel 14 to rotate the protective cover 7. At this time, the protective cover 7 and the protective cover 8 are raised to a certain angle, which can block the position of the control panel 2. During use, the control panel 2 can only be viewed from the user's perspective, which can prevent password leakage. When the terminal body 1 needs to be placed in a fixed position, the protective cover 8 is pushed, and the pin 17 is moved by pressing the limit bracket 15. When the protective cover 8 is in place, the limit bracket 15 is released, and the pin 17 is limited by the spring 18. The protective cover is then flipped to the back of the terminal body 1 by the connection of the worm gear 13 and the worm wheel 14, which can support the terminal body 1, making it easy to use and adjust the support angle.
