[0002] In modern intelligent transportation systems, the ETC (electronic toll collection system) self-service issuance terminal plays an important role. It provides users with a convenient and fast way to obtain ETC equipment. It does not require manual intervention and is fully automated. Users only need to follow the instructions of the terminal and complete the application and issuance of ETC equipment in a few minutes through steps such as ID card recognition, license plate recognition, information entry, and fee payment. The built-in item pickup component of the terminal can accurately and safely take out the ETC equipment from the equipment library according to the user's order, and send it to the pickup port through the transmission system. The user can take the equipment away after confirming that it is correct. In such a terminal, the item pickup component is one of the core components, which is responsible for accurately taking out the ETC equipment, such as ETC tags or cards, from the internal storage area and then delivering it to the user. In addition, considering the efficient service requirements in a high-traffic environment, the pickup component needs to be able to respond quickly and have high reliability, be able to operate stably for a long time, reduce the failure rate, and ensure that users can quickly complete the equipment collection process. In order to improve the user experience, the design of the pickup component should also focus on humanization to ensure that the equipment removal and delivery process is intuitive and easy to operate.

[0003] Most of the existing item picking components of the ETC self-service issuance terminals can only transport and pick up ETC devices of a single size. The specifications and sizes of ETC devices vary, resulting in low adaptability and compatibility. In addition, hard clamps are used to clamp the ETC devices, which can easily cause wear and tear on the ETC devices.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention facilitates the clamping and fixing of ETC devices of different sizes by arranging the coordination of structures such as the clamping plate and the airbag, and pushes the clamping plate housing to move in the direction close to the baffle plate through the telescopic rod. Because the first gear on the side of the clamping plate housing is meshed with the second rack, the movement of the clamping plate housing drives the first gear to rotate on the second rack and drives the worm to rotate, thereby rotating the turbine meshed with the worm, and driving the turntable to rotate along the four arc grooves in the direction of approaching the center, applying a force to the sliding rod inside the arc groove, so that the sliders at the top of the four sliding rods slide in the direction of approaching each other with the inside of the slide groove under the limit of the limit block. The airbag moves so that it abuts against and is squeezed against the side of the ETC device, deforms and wraps the side of the ETC device, and clamps and fixes the ETC device at the center of the top of the clamp shell through the airbag on the clamp plate. Because the number of teeth on the second rack is fixed, the distance between the four clamp plates is also fixed, and the size of the ETC device is not fixed. Therefore, when the clamp plate fixes the ETC device, the degree to which the airbag is squeezed by ETC devices of different sizes is also different, so that ETC devices of different sizes can be clamped and fixed within the tolerance range of the airbag deformation, thereby improving the application range of the device;

[0018] The present invention improves the adaptive performance of the device by arranging the coordination of structures such as the airbag and the piston rod. When the airbag abuts against and is squeezed against the side of the ETC device, the slider continues to move toward the direction close to the ETC device, causing the airbag to deform and wrap the side of the ETC device, while squeezing the piston rod inside the airbag, causing the piston rod to move toward the direction close to the sealing cylinder and squeeze the spring, while squeezing the air inside the sealing cylinder and the sealing groove, supporting and cushioning the airbag through air pressure and spring elastic force, avoiding the occurrence of wear on the ETC device when the hard clamping plate clamps and fixes the ETC device, and at the same time improving the stability of the clamping plate clamping and fixing the ETC device;

[0019] The present invention facilitates users to pick up goods from the ETC device by arranging the cooperation of structures such as the third rack and the first rack. When the splint shell drives the first gear to move on the second rack to half the distance of the second rack, the splint shell will drive the third rack to move below the second gear and mesh with the second gear. The movement of the third rack causes the second gear and the picking frame to rotate, driving the baffle to rotate in the direction away from the splint shell to open the outlet. When the first gear moves to one end of the second rack close to the baffle, the third rack drives the second gear to rotate to a 90-degree position. At this time, the splint shell Half of the plate shell moves to the inside of the pickup frame, and at the same time, the top of the first gear engages with the first rack. When the splint shell is finally completely moved into the inside of the pickup frame, the baffle rotates to a 180-degree position, and the first gear rotates in the opposite direction under the action of the teeth of the first rack. The splint moves away from the ETC device through transmission, reducing the clamping strength of the ETC device, allowing users to easily remove the ETC device from the splint shell. At the same time, the fixing and conveying processes are carried out simultaneously, simplifying the pickup process, and reducing the time required for pickup, thereby improving the smoothness of user operations and user experience.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 9 As shown, the present invention provides an item picking component of an ETC self-service issuing terminal, including a clamping mechanism 1, a buffer mechanism 2 is arranged on the clamping mechanism 1, a main body mechanism 3 is arranged on the clamping mechanism 1, a driving mechanism 4 is arranged inside the main body mechanism 3, the clamping mechanism 1 is located inside the driving mechanism 4, and an ETC device 5 is arranged inside the main body mechanism 3;

[0034] The top of the slide bar 106 passes through the inner wall of the arc groove 102 and extends to the top of the turntable 101 . The slider 107 is located above the turntable 101 . The worm 104 and the first gear 105 are both located below the turntable 101 .

[0035] The above scheme is adopted: by setting the coordination of structures such as the splint 109 and the airbag 110, it is convenient to clamp and fix ETC devices of different sizes, and the splint housing 402 is pushed to move in the direction close to the baffle 306 by the telescopic rod 401. Because the first gear 105 on the side of the splint housing 402 is engaged with the second rack 311, the movement of the splint housing 402 will drive the first gear 105 to rotate on the second rack 311 and drive the worm 104 to rotate, thereby rotating the turbine 103 engaged with the worm 104, and driving the turntable 101 to rotate along the four arc grooves 102 in the direction of approaching the center, applying a force to the sliding rod 106 inside the arc groove 102, so that the slider 107 on the top of the four sliding rods 106 is in the limit block 404. Under the limit, they slide in the direction of approaching each other inside the slide groove 403, so that the airbag 110 is abutted against and squeezed against the side of the ETC device, so that the airbag 110 is deformed and wraps the side of the ETC device, and the ETC device is clamped and fixed at the center position of the top of the clamp housing 402 through the airbag 110 on the clamp plate 109. Because the number of teeth on the second rack 311 is fixed, the distance between the four clamp plates 109 is also fixed, and the size of the ETC device is not fixed. Therefore, when the clamp plate 109 fixes the ETC device, the degree to which ETC devices of different sizes squeeze the airbag 110 is also different, so that ETC devices of different sizes can be clamped and fixed within the tolerance range of the deformation of the airbag 110, thereby improving the application range of the device.

[0036] like Figure 7 As shown, the buffer mechanism 2 includes a sealing cylinder 201, a piston rod 202 is slidably connected inside the sealing cylinder 201, a spring 203 is fixedly connected inside the sealing cylinder 201, a sealing groove 204 is opened inside the sealing cylinder 201, the inner wall of the sealing cylinder 201 is elastically connected to the piston rod 202 through the spring 203, the spring 203 is located inside the sealing groove 204, the side of the splint 109 away from the airbag 110 is fixedly connected with two sealing cylinders 201, the piston rod 202 penetrates the sealing cylinder 201 and the splint 109 and extends to the inside of the airbag 110, and the piston rod 202 is slidably connected to the splint 109.

[0037] The above scheme is adopted: by setting the coordination of structures such as the airbag 110 and the piston rod 202, the adaptive performance of the device is improved. When the airbag 110 is against and squeezed against the side of the ETC device, the slider 107 slider 107 continues to move in the direction close to the ETC device, causing the airbag 110 to deform and wrap the side of the ETC device, and at the same time squeeze the piston rod 202 inside the airbag 110, so that the piston rod 202 moves in the direction close to the sealing cylinder 201 and squeezes the spring 203, and at the same time squeezes the air inside the sealing cylinder 201 and the sealing groove 204, and supports and cushions the airbag 110 through air pressure and the elastic force of the spring 203, thereby avoiding the wear of the ETC device when the hard clamp 109 clamps and fixes the ETC device, and at the same time can also improve the stability of the clamp 109 in clamping and fixing the ETC device.

[0039] The pickup frame 304 passes through the inner wall of the ETC terminal body 301 and extends to the front of the ETC terminal body 301. The card swiping area 307 and the button 308 are both located above the pickup frame 304. The display screen 309 is located above the card swiping area 307 and the button 308. The baffle 306 is rotatably connected to the inner wall of the pickup frame 304. The first rack 310 is located above the second rack 311. The first rack 310 and the second rack 311 are both located on the side of the baffle 306 away from the second gear 305. A plurality of teeth are provided at the bottom of the first rack 310, and a plurality of teeth are provided at the top of the second rack 311. The first rack 310 is located on the side of the second rack 311 close to the baffle 306. The first gear 105 is meshed with the top of the second rack 311, and the first gear 105 is meshed with the bottom of the first rack 310.

[0040] The driving mechanism 4 includes a telescopic rod 401 slidably connected to the inside of the pickup shell 302, a splint shell 402 is fixedly connected to the telescopic rod 401, four slide grooves 403 are evenly opened on the top of the splint shell 402, and two limit blocks 404 are fixedly connected to the inner walls of the four slide grooves 403, a third rack 405 is fixedly connected to the telescopic rod 401, and an anti-collision pad 406 is fixedly connected to the top of the telescopic rod 401.

[0041] The anti-collision pad 406 is located between the four slide grooves 403, the splint shell 402 is slidingly connected to the inner wall of the pickup shell 302, the telescopic rod 401 is located on the side of the splint shell 402 away from the baffle 306, the slider 107 is slidingly connected to the slide groove 403, the limit groove 108 is clamped with the limit block 404, the turntable 101 and the worm 104 are respectively rotatably connected to the inner wall of the splint shell 402, the second rack 311 penetrates the inner wall of the splint shell 402 and extends to the side of the splint shell 402 close to the second rack 311, the third rack 405 is located on the side of the splint shell 402 away from the first gear 105, and the splint shell 402 is located below the discharge trough 303.

[0042] The above scheme is adopted: Bluetooth, elastic lock, battery, etc. are arranged inside the main body mechanism 3, and the generated QR code is attached to the device. After the user scans the code and connects Bluetooth and positioning, the corresponding window is opened according to the logical requirements of the code (the user end needs to complete the payment). The above is the prior art. By setting the coordination of the third rack 405 and the first rack 310 and other structures, it is convenient for users to pick up goods from the ETC device. When the splint shell 402 drives the first gear 105 to move on the second rack 311 to half the distance of the second rack 311, the splint shell 402 will drive the third rack 405 to move to the bottom of the second gear 305 and mesh with the second gear 305. The movement of the third rack 405 causes the second gear 305 to rotate with the pickup frame 304, driving the baffle 306 to rotate in the direction away from the splint shell 402 to open the exit. When the first gear 105 moves to one end of the second rack 311 close to the baffle 306, the third rack 405 drives the second gear 305 to rotate to a 90-degree position. At this time, half of the splint housing 402 moves to the inside of the pickup frame 304, and at the same time, the top of the first gear 105 engages with the first rack 310. When the splint housing 402 finally moves completely to the inside of the pickup frame 304, the baffle 306 rotates to a 180-degree position, and the first gear 105 rotates in the opposite direction under the action of the teeth of the first rack 310. Through transmission, the splint 109 moves away from the ETC device, reducing the clamping strength of the ETC device, allowing the user to easily remove the ETC device from the splint housing 402, and at the same time, the fixing and conveying processes are carried out simultaneously, simplifying the pickup process, and reducing the time required for pickup, thereby improving the smoothness of user operations and user experience.

[0043] The working principle and use process of the present invention are as follows: first, the user only needs to follow the instructions of the terminal, scan the QR code and connect Bluetooth and positioning, then open the corresponding window according to the logical requirements of the code (the user end needs to complete the payment), and complete the application for the ETC device through steps such as ID card recognition, license plate recognition, information entry, and fee payment, so that the ETC terminal body 301 releases the ETC device through the internal release structure, so that it falls from the discharge slot 303 into the interior of the pickup shell 302, and the ETC device falls between the four splints 109 above the splint shell 402, and abuts against the anti-collision pad 406, so as to avoid the ETC device from colliding with the splint shell 402 when it falls above the splint shell 402, generating an impact force that causes damage to the ETC device;

[0044] Then, the telescopic rod 401 is used to push the splint housing 402 to move toward the baffle 306. Because the first gear 105 on the side of the splint housing 402 is meshed with the second rack 311, the movement of the splint housing 402 will drive the first gear 105 to rotate on the second rack 311 and drive the worm 104 to rotate, thereby rotating the turbine 103 meshed with the worm 104, and driving the turntable 101 to rotate along the four arc grooves 102 in the direction of approaching the center, applying a force to the slide bar 106 inside the arc groove 102, so that the sliders 107 on the top of the four slide bars 106 slide in the direction of approaching each other with the inside of the slide groove 403 under the limit of the limit block 404, so that the airbag 110 is pressed against the side of the ETC device and squeezed, so that the airbag 110 is deformed and wraps the ETC device The side of the airbag 110 will squeeze the piston rod 202 inside the airbag 110, causing the piston rod 202 to move toward the direction close to the sealing cylinder 201 and squeeze the spring 203. At the same time, it will squeeze the air inside the sealing cylinder 201 and the sealing groove 204, and support and cushion the airbag 110 through the air pressure and the elastic force of the spring 203. The ETC device is clamped and fixed at the center position of the top of the clamping plate housing 402 through the airbag 110. Because the number of teeth on the second rack 311 is fixed, the distance between the four clamping plates 109 is also fixed, and the size of the ETC device is not fixed. Therefore, when the clamping plate 109 fixes the ETC device, the degree to which the airbag 110 is squeezed by ETC devices of different sizes is also different, so that ETC devices of different sizes can be clamped and fixed;

[0045] When the splint shell 402 drives the first gear 105 to move on the second rack 311 to half the distance of the second rack 311, the splint shell 402 will drive the third rack 405 to move to the bottom of the second gear 305 and mesh with the second gear 305. The movement of the third rack 405 causes the second gear 305 and the pickup frame 304 to rotate, driving the baffle 306 to rotate away from the splint shell 402 to open the outlet. When the first gear 105 moves to the end of the second rack 311 close to the baffle 306, the third rack 405 drives the second gear 305 rotates to a 90-degree position, at which point half of the splint housing 402 moves into the interior of the pickup frame 304, and at the same time, the top of the first gear 105 engages with the first rack 310. When the splint housing 402 is finally completely moved into the interior of the pickup frame 304, the baffle 306 rotates to a 180-degree position, and the first gear 105 rotates in the opposite direction under the action of the teeth of the first rack 310, and the splint 109 is moved away from the ETC device through transmission, thereby reducing the clamping strength of the ETC device, allowing the user to easily remove the ETC device from the splint housing 402.
