Description

Technical Field

[0001] The utility model relates to the technical field of high-speed code scanners, in particular to an adjustable sunshade device for code scanners. Background Art

[0002] A highway toll scanner is an electronic device that uses barcode or QR code scanning technology, combined with a payment system, to enable quick payment of highway tolls. It automatically completes the deduction of tolls by scanning the payment QR code provided by the car owner (such as WeChat, Alipay, etc.) without the need for human intervention, greatly improving toll collection efficiency and reducing vehicle waiting time.

[0003] Existing highway toll scanners still have certain shortcomings in actual use: they lack an adjustable sunshade. When drivers and passengers scan codes in the extra-wide lanes at exits, the sun's rays reflect off their phone screens, seriously affecting the efficiency of mobile payment. In this case, even if they quickly block the sun with an object, drivers often need to repeatedly adjust the angle of their phones, which affects the speed of toll collection. To address this shortcoming of existing technology, this utility model designs an adjustable sunshade for the scanner. Utility Model Content

The other end of the push rod 29 is hingedly connected to the first hinged seat 22.

[0023] See also Figure 1-2 A protective cover 8 is installed on one side of the outer surface of the partition 1, and the protective cover 8 covers the outside of the L-shaped fixing plate 23.

[0024] The other components of the regulating structure 2 and the first relay 4 , the second relay 5 , the third relay 6 and the fourth relay 7 are protected by a protective cover 8 .

[0025] See also Figure 6, the first light-sensing switch inside the scanner body 21 is connected in series with the coil J1 of the first relay 4 to form a first branch, and the second light-sensing switch inside the scanner body 21 is connected in series with the coil J2 of the second relay 5 to form a second branch. The normally open contact J1K1 of the first relay 4, the first normally open contact J2K1 of the second relay 5, and the coil J3 of the third relay 6 are connected in series to form a third branch. The normally closed contact J1K2 of the first relay 4, the second normally open contact J2K2 of the second relay 5, and the coil J4 of the fourth relay 7 are connected in series to form a fourth branch. The fourth branch, the first branch, the second branch, and the third branch are connected in parallel, and the two ends of the first branch are connected to the positive and negative poles of the power supply. The first normally open contact J3 of the third relay 6, the servo motor 25, and the second normally open contact J3K2 of the third relay 6 are connected in series to form a fifth branch, which is connected in parallel with the first branch; the first normally open contact J3K1 of the third relay 6 is connected to the positive pole of the servo motor 25, and the second normally open contact J3K2 of the third relay 6 is connected to the negative pole of the servo motor 25. The second normally open contact J4K2 of the fourth relay 7, the servo motor 25 and the first normally open contact J4K1 of the fourth relay 7 are connected in series to form a sixth branch, and the sixth branch is connected in parallel with the first branch; the second normally open contact J4K2 of the fourth relay 7 is connected to the negative pole of the servo motor 25, and the first normally open contact J4K1 of the fourth relay 7 is connected to the positive pole of the servo motor 25.

[0026] The second light-sensing switch is set on the side of the display screen of the barcode scanner body 21, and the first light-sensing switch is set above the sunshade of the barcode scanner body 21. When the first light-sensing switch and the second light-sensing switch are exposed to light, the coil J1 of the first relay 4 and the coil J2 of the second relay 5 are turned on. At this time, the normally open contact J1K1 of the first relay 4 and the first normally open contact J2K1 of the second relay 5 are turned on, and the coil J3 of the third relay 6 is turned on. Correspondingly, the first normally open contact J3K1 of the third relay 6 and the second normally open contact J3K2 of the third relay 6 are turned on. Due to the The normally closed contact J1K2 is open, so the coil J4 of the fourth relay 7 is not energized, and the servo motor 25 can rotate forward; when the first light-sensing switch is not illuminated and the second light-sensing switch is illuminated, the first normally open contact J2K1 of the second relay 5 is closed. Since the normally closed contact J1K2 of the first relay 4 is closed, the coil J4 of the fourth relay 7 is energized, thereby closing the second normally open contact J4K2 of the fourth relay 7 and the first normally open contact J4K1 of the fourth relay 7. Since the first normally open contact J3 of the third relay 6 is not energized, the servo motor 25 can be reversed.

[0027] Working principle: when the barcode scanner's adjustable sunshade device is used, in the initial state, the barcode scanner body 21 is in a parallel state with the through hole 31, and the second light sensor switch on the barcode scanner body 21 is set on the side of the barcode scanner body 21 display screen, and the first light sensor switch is set above the sunshade of the barcode scanner body 21. When the first light sensor switch and the second light sensor switch are exposed to light, the barcode scanner body 21 display screen has reflections, which is difficult to pay. At this time, the coil J1 of the first relay 4 and the coil J2 of the second relay 5 are turned on. At this time, the normally open contact J1K1 of the first relay 4 and the first normally open contact J2K1 of the second relay 5 are turned on, and the coil J3 of the third relay 6 is turned on. The corresponding first normally open contact J3K1 of the third relay 6 and the second normally open contact J3K2 of the third relay 6 are turned on. Since the normally closed contact J1K2 of the first relay 4 is open, the coil J4 of the fourth relay 7 is not energized, which can make the servo motor 25 rotate forward. In this way, its output can drive the articulated short rod 26 to rotate. Due to the articulation of the articulated short rod 26 and the articulated long rod 27, when the articulated short rod 26 rotates, the articulated long rod 27 can rotate and push the push rod 29 forward. Due to the articulation of the push rod 29 and the first articulated seat 22, the barcode scanner body 21 can be folded downward around the two support points below, so that the display screen of the barcode scanner body 21 can be positioned downward, thereby avoiding direct sunlight. When the sunlight is not strong, the first light sensor switch is exposed to light and the second light sensor switch is not exposed to light, the first normally open contact J2K1 of the second relay 5 is closed. Since the normally closed contact J1K2 of the first relay 4 is closed itself, the coil J4 of the fourth relay 7 is energized, thereby closing the second normally open contact J4K2 of the fourth relay 7 and the first normally open contact J4K1 of the fourth relay 7. Since the first normally open contact J3 of the third relay 6 is not energized, the servo motor 25 can be reversed to pull the push rod 29 back.
