Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and more specifically, to a mobile robot for highway toll stations that is easy to adjust. Background Technology

[0002] In the daily operation of highway toll stations, toll collection often requires frequent processing of toll cards or receipts. In the current technology, toll station staff usually rely on manual handling of receipts. However, due to the inadequacy of the existing system in terms of height adjustment, staff need to manually adjust their posture or use auxiliary tools when dealing with vehicles of different heights, which increases labor intensity and easily leads to inconvenience in operation. Traditional equipment is difficult to provide suitable height adjustment during rapid passage, affecting toll collection efficiency and staff comfort.

[0003] Furthermore, existing equipment is often unable to quickly and efficiently remove toll cards or tickets from the robot's gripping mechanism. Due to design limitations, staff have to go through cumbersome steps when retrieving cards or tickets, increasing time costs and potentially causing issues such as insecure gripping or jamming. To improve the efficiency of toll stations, there is an urgent need for a design that can quickly remove toll cards or tickets while providing convenient height adjustment, thereby reducing manual intervention, improving work efficiency, and optimizing the toll collection process. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides an easily adjustable mobile robot for highway toll stations to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a mobile robot for easy adjustment at a high-speed toll station, comprising a support plate, a clamping mechanism on the support plate, the clamping mechanism comprising a micro motor, a screw, a transmission frame, a connecting rod, a clamping block, and a positioning mechanism, the micro motor being fixed on the support plate, the screw being fixed on the output end of the micro motor, the transmission frame being threadedly connected to the outside of the screw, the connecting rod being rotatably connected to the transmission frame and the support plate, the clamping block being connected to the top of the connecting rod, and the positioning mechanism comprising a fixed shaft, a movable groove, a push spring, a positioning block, a clamping wheel, and a positioning groove, the fixed shaft being fixed on the clamping block, multiple sets of movable grooves being provided on the top surface of the fixed shaft, the push springs being connected within the multiple sets of movable grooves, the positioning block being fixed to the top of the multiple sets of push springs, the clamping wheel being rotatably mounted on the top surface of the fixed shaft, and multiple sets of positioning grooves being provided on the inner side of the clamping wheel.

[0008] The present invention is further configured such that an adjustment mechanism is provided on the outer side of the support plate. The adjustment mechanism includes an adjustment arm, a rotating rod, a mounting frame, a drive motor, a drive synchronous pulley, a transmission synchronous pulley, and a synchronous belt. The adjustment arm is fixed to the outer wall of the support plate, the rotating rod is fixed to the bottom end of the adjustment arm, the mounting frame rotates on the outer wall of the rotating rod, the drive motor is fixed on the mounting frame, the drive synchronous pulley is fixed on the mounting frame, the transmission synchronous pulley is fixed on the outer wall of the rotating rod, and the synchronous belt is provided on the outer walls of the drive synchronous pulley and the transmission synchronous belt.

[0009] This invention is further configured such that rubber strips are provided on the outer walls of the multiple sets of clamping wheels, and the rubber strips are arranged in multiple sets distributed on the outer walls of the multiple sets of clamping wheels. The rubber strips increase the friction between the clamping wheels and the payment card or ticket, effectively preventing slippage and unstable clamping, ensuring that the payment card or ticket can be firmly gripped, and improving operational stability and safety.

[0010] The present invention is further configured such that all of the multiple sets of positioning blocks are spherical. The spherical positioning blocks can move smoothly within the positioning grooves, reducing friction and wear, allowing the clamping wheels to be positioned more smoothly, ensuring precise operation, and improving the stability and reliability of clamping.

[0011] This invention is further characterized in that all of the multiple positioning grooves are arc-shaped. The arc-shaped positioning grooves can better fit the spherical positioning blocks, reduce friction, and ensure that the positioning blocks slide smoothly in the grooves, thereby making the positioning of the clamping wheels more accurate and improving the smoothness and efficiency of operation.

[0012] This invention is further characterized in that the outer sides of all sets of positioning grooves are provided with rounded corners. The rounded corner design reduces friction between the positioning block and the positioning groove, avoids jamming, ensures stability during operation, extends the service life of the equipment, and improves the stability of the equipment.

[0013] The present invention is further configured such that a movable base is connected to the bottom end of the mounting frame. The movable base design allows the entire robot to move flexibly, adapting to different working environments and improving the robot's operational efficiency and flexibility within highway toll stations.

[0014] This invention is further configured such that tracks are provided on both sides of the mobile base. The tracks provide better traction and stability, ensuring the robot can move smoothly in complex ground conditions, increasing the robot's adaptability and ground clearance, and improving work efficiency.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides an easily adjustable mobile robot for highway toll stations, which has the following advantages:

[0017] 1. The clamping mechanism uses a micro motor to drive the screw to rotate, causing the transmission frame to slide along the screw, which in turn drives the connecting rod to rotate. The connecting rod pushes the clamping block to move, which in turn drives the clamping wheel to clamp the toll card or ticket. This design allows the toll card or ticket to be clamped securely, and the rotation of the clamping wheel ensures a smooth and stable gripping process, reducing manual intervention and improving the level of automation and work efficiency.

[0018] 2. The positioning mechanism uses a spherical positioning block and an arc-shaped positioning groove to ensure that the clamping wheel can be accurately positioned when removing the toll card or ticket. The positioning block, under the action of the push spring, fixes the clamping wheel in the appropriate position, avoiding jamming and positional deviation, ensuring that the clamping wheel can operate stably, improving working accuracy and stability, and reducing misoperation.

[0019] 3. The adjustment mechanism drives the synchronous pulley and synchronous belt through the drive motor, which causes the rotating rod to drive the adjustment arm to rotate, thereby realizing the adjustment of the support plate height. This design can adjust the height of the support plate according to different needs, making the operation more flexible and adaptable to vehicles of different heights. Through this height adjustment method, the operator can easily adjust the position of the robot, improving work efficiency and operational flexibility. Attached Figure Description
