[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0022] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.
[0023] Example:
[0024] Reference Figure 1-Figure 4 A vehicle-mounted ETC device includes a box body 1. An antenna is arranged inside the box body 1, which is used to receive and send wireless signals, communicate and transmit data with the antenna of the toll station to complete electronic toll payment. A card slot is also arranged on the box body 1, which is used to read the information on the vehicle-mounted ETC card or label, identify the vehicle and payment information, and realize the automatic deduction function. A processor and a memory are also provided, which are used to process the received data and information, perform calculations and judgments, and the memory is used to save vehicle and transaction-related information for subsequent query and management. A power supply is also provided to ensure the normal operation of the vehicle-mounted ETC system. A power supply system is required to provide a stable power supply, which is usually connected to the vehicle's battery or a vehicle-mounted power adapter. The security control module is used to encrypt and verify payment information, ensure the security of transactions, and prevent information leakage and illegal operations.
[0025] In addition, a connection groove 101 is provided on the box body 1, and a connection block 2 is detachably connected to the connection groove 101, and the connection block 2 has the same cross-section as the connection groove 101. The connection block 2 can be aligned with the connection groove 101 and plugged in, thereby completing the connection of the connection block 2.
[0026] The connection block 2 is also fixedly connected to a limiting plate 201 , and the limiting column 202 is slidably connected to the limiting plate 201 . A limiting groove is provided on the box body 1 , and the limiting column 202 is detachably connected in the limiting groove.
[0027] Here, the diameter of the limit slot is slightly smaller than the diameter of the limit column 202, so that the limit slot and the limit column 202 can be interference fit. When the connecting block 2 is plugged into the box body 1, the limit column 202 is pressed toward the direction of the limit slot, and then the limit column 202 can be plugged into the limit slot, and then the position of the connecting block 2 can be limited. Here, screws can also be used to limit the position of the limit plate 201.
[0028] A suction cup 8 is fixedly connected to the connecting block 2, a negative pressure cylinder 3 is also fixedly connected to the connecting block 2, and a movable rod 4 is slidably connected to the negative pressure cylinder 3, and one end of the movable rod 4 is fixedly connected to a piston 5, and the piston 5 fits with the inner wall of the negative pressure cylinder 3, and a slide groove 301 is opened in the negative pressure cylinder 3, and a slider 401 is fixedly connected to the outer wall of the movable rod 4, the slider 401 is slidably connected to the slide groove 301, and the slider 401 can slide in the slide groove 301, which can prevent the movable rod 4 from moving to the outside of the negative pressure cylinder 3 on the one hand, and limit the position of the piston 5 on the other hand, so that it can only move in the negative pressure cylinder 3.
[0029] It needs to be explained that, in order to improve the stability of the suction cup 8, a guide channel is also opened in the connecting block 2, and the cavity on one side of the piston 5 is connected with the suction cup 8 through the guide channel. When the suction cup 8 needs to be pressed on the glass, the movable rod 4 needs to be pressed to fix the piston 5 on the movable rod 4. At this time, the air between the suction cup 8 and the glass will be discharged to the outside of the glass. At this time, the movable rod 4 is moved outward, and the piston 5 moves outward synchronously, thereby generating a negative pressure effect in the guide channel to improve the adsorption effect between the suction cup 8 and the glass.
[0030] In addition, a mounting plate 6 is fixedly connected to the end of the movable rod 4 away from the piston 5, and a limiting bolt 7 is threadedly connected to the mounting plate 6, and the end of the limiting bolt 7 can be against the outer wall of the connecting block 2. When the suction cup 8 needs to be adsorbed, the limiting bolt 7 can be rotated clockwise at this time, and the end of the limiting bolt 7 can be against the outer wall of the connecting block 2, thereby moving the movable rod 4 toward the outside of the negative pressure cylinder 3, thereby generating a negative pressure effect in the diversion channel.
[0031] When there is no need to adsorb the suction cup 8, the limit bolt 7 can be rotated counterclockwise, and the end of the limit bolt 7 will not be against the outer wall of the connecting block 2, thereby improving the adsorption effect between the suction cup 8 and the glass, enhancing the stability of the suction cup 8, reducing the risk of the suction cup 8 falling or falling off, ensuring that it is safely and reliably fixed on the glass, reducing the phenomenon of the box body 1 falling off, and reducing the movement friction between the surface of the suction cup 8 and the glass, reducing the loss rate of the suction cup 8, and extending the service life of the suction cup 8.
[0032] By using the suction cup 8 to fix the box body 1 on the vehicle glass, the box body 1 can be fixed without using adhesive. When the box body 1 needs to be disassembled, the limit column 202 can be disassembled, and then the box body 1 can be easily disassembled from the connecting block 2 to prevent the outer shell of the box body 1 from being damaged. At the same time, it can also prevent glue marks from being left on the glass, so that it will not block the driver's line of sight, thereby improving the practicality of the device.
[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
