Description

Technical Field

[0001] This invention relates to the field of intersection control, specifically to a road intersection control device. Background Technology

[0002] Traffic lights are signals that direct traffic flow. They generally consist of red, green, and yellow lights. A red light indicates "stop," a green light indicates "go," and a yellow light indicates "warning." Traffic lights are categorized as follows: motor vehicle traffic lights, non-motor vehicle traffic lights, pedestrian crossing traffic lights, directional indicator lights (arrow lights), lane traffic lights, flashing warning lights, and level crossing traffic lights. At intersections, red, yellow, and green traffic lights are displayed on all four sides. Traffic lights are an internationally recognized standard for traffic signals. Traffic lights: red means stop, green means go. At intersections, vehicles from several directions converge, some going straight, some turning. Who gets priority? That's where the traffic lights come in. When the red light is on, going straight or turning left is prohibited, but turning right is permitted if it doesn't obstruct pedestrians or other vehicles. When the green light is on, vehicles are permitted to go straight or turn. When the yellow light is on, stop before the stop line or pedestrian crossing; vehicles that have already crossed the stop line may continue. When the yellow light is flashing, it warns vehicles to be cautious.

[0003] When traffic lights malfunction, solar-powered portable traffic lights are typically used as a substitute for directing traffic during the repair process.

[0004] However, the solar panels on existing portable solar traffic lights are directly mounted on the base. The cost of the solar panels is high, and maintenance is inconvenient. When the traffic light is hit, the solar panels are easily damaged, and the replacement cost is high. Summary of the Invention

[0017] 1. This invention features a flipping mechanism that allows the solar panel to flip upwards with the light-receiving surface facing the working box when the main body of the device is not in use, preventing damage from collisions. When the main body of the device is needed, simply start the motor to move the sliding plate downwards, which in turn causes the solar panel to flip downwards and open via the first connecting rod.

[0018] 2. By setting up a support mechanism, the present invention enables the two sets of support legs to automatically flip downward when the sliding plate moves downward and causes the solar panel to flip downward, thereby lifting the entire device upward and allowing the casters to leave the ground, thus improving the stability of the main body of the equipment during use.

[0019] 3. By setting a locking mechanism, the present invention ensures that when the sliding plate moves downward to fully open the support leg and the solar panel, the locking block moves to the bottom of the rotating rod. At this time, the sliding plate is fixed and cannot move upward, that is, the solar panel and the support leg are fixed and cannot be flipped. At the same time, the threaded sleeve moves to the bottom of the threaded rod and separates from the threaded rod. At this time, the motor and the threaded rod can be disassembled.

[0020] 4. By setting up a protective mechanism, when an external object impacts the device, it will first be blocked by the arc-shaped baffle or side baffle. Through the setting of the first damper, the second damper and the shock-absorbing spring, the impact force can be effectively reduced to prevent damage to the main body of the equipment. At the same time, when the arc-shaped baffle is impacted, the side wall of the arc-shaped baffle will contact the bottom of the solar panel. At this time, the solar panel and the support leg can automatically reset and retract, preventing damage to the solar panel or support leg caused by the impact of external objects.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] The embodiments of the present invention will now be described.

[0036] A road intersection control device, such as Figure 1-5 As shown, the device includes a main body 100, with multiple sets of signal lights 101 on the outer wall of the main body 100, a work box 102 at the bottom of the main body 100, multiple sets of casters 103 at the bottom of the work box 102, and a flipping mechanism 200 on the outer wall of the work box 102.

[0037] The flipping mechanism 200 includes a solar panel 201. Two sets of solar panels 201 are rotatably connected to the outer wall of the working box 102. The bottom ends of the two sets of solar panels 201 are rotatably connected to a first connecting rod 202. Two sets of first sliding grooves 203 are provided on the outer wall of the working box 102, and the two sets of first connecting rods 202 extend into the interior of the working box 102 through the two sets of first sliding grooves 203 respectively. A sliding plate 204 is provided below one end of the two sets of first connecting rods 202 inside the working box 102. Multiple sets of columns 205 are provided at the top of the sliding plate 204, and a pressure plate 206 is provided at the top of the multiple sets of columns 205. The top of the pressure plate 206 is provided with a hollow shaft 207. The top of the main body 100 of the equipment is detachably connected to a motor 208. The output end of the motor 208 is provided with a threaded rod 209, and the bottom end of the threaded rod 209 extends into the interior of the hollow shaft 207. The top of the hollow shaft 207 is provided with a threaded sleeve 210, and the inner wall of the threaded sleeve 210 is threadedly connected to the outer wall of the threaded rod 209. The outer wall of the sliding plate 204 is provided with two sets of protrusions 211. The bottom of the inner wall of the working box 102 is provided with two sets of guide rods 212, and the outer walls of the two sets of guide rods 212 are slidably connected to the inner walls of the two sets of protrusions 211 respectively.

[0038] When the main body 100 of the equipment is not in use, the solar panel 201 is flipped upwards with the light-receiving surface facing the working box 102 to prevent the solar panel 201 from being damaged by collision. When the main body 100 of the equipment is needed, simply start the motor 208. The motor 208 drives the threaded rod 209 to rotate, the threaded rod 209 drives the threaded sleeve 210 to move downwards, the threaded sleeve 210 drives the hollow shaft 207 to move downwards, the hollow shaft 207 drives the pressure plate 206 to move downwards, the pressure plate 206 drives multiple sets of columns 205 to move downwards, the columns 205 drive the sliding plate 204 to move downwards, and the sliding plate 204 can drive the first connecting rod 202 to move downwards. The end of the first connecting rod 202 can then drive the solar panel 201 to flip downwards and open. The guide rod 212 is set to prevent the threaded sleeve 210 from rotating with the threaded rod 209.

[0039] Please refer to this carefully. Figure 1-5 The outer wall of the work box 102 is provided with a support mechanism 300, which includes a first rotating shaft 301. Two sets of first rotating shafts 301 are rotatably connected to the outer wall of the work box 102. Two sets of support legs 302 are fixedly connected to the outer walls of the two sets of first rotating shafts 301 respectively. Anti-slip pads 303 are provided at the ends of the multiple sets of support legs 302. A second rotating shaft 304 is rotatably connected to the end of the two sets of support legs 302 that are close to each other. A second connecting rod 305 is fixedly connected to the outer walls of the two sets of second rotating shafts 304. The outer wall of the work box 102 has two sets of The second slide groove 306, and the two sets of second connecting rods 305 extend into the interior of the work box 102 through the second slide groove 306. The bottom end of one side of the two sets of second connecting rods 305 extending into the interior of the work box 102 is provided with a third connecting rod 307, and the bottom end of the third connecting rod 307 extends to the top of the sliding seat. The bottom ends of the two sets of first connecting rods 202 and the two sets of third connecting rods 307 are provided with T-shaped blocks 309. The top of the sliding plate 204 is provided with multiple sets of T-shaped grooves 308, and the multiple sets of T-shaped blocks 309 are slidably connected to the inner walls of the multiple sets of T-shaped grooves 308 respectively.

[0040] When the sliding plate 204 moves downward, it drives the third connecting rod 307 to move downward. The third connecting rod 307 drives the second connecting rod 305 to move downward. The second connecting rod 305 drives the second rotating shaft 304 to move downward. The second rotating shaft 304 can then drive the two sets of support legs 302 to flip downward. When the support legs 302 touch the ground, they continue to flip, which can drive the entire device to lift upward, thereby causing the caster wheel 103 to leave the ground. This prevents the main body of the equipment 100 from moving due to the ground slope during use. The anti-slip pads 303 improve the friction between the support legs 302 and the ground, improving the stability of the entire device during use. The T-shaped block 309 and T-shaped groove 308 allow the ends of the first connecting rod 202 and the third connecting rod 307 to slide at the top of the sliding plate 204, so that the first connecting rod 202 can smoothly drive the solar panel 201 to flip, and the third connecting rod 307 can drive the support legs 302 to flip through the second connecting rod 305.

[0041] Please refer to this carefully. Figure 1-7 The bottom of the inner wall of the work box 102 is provided with a locking mechanism 400. The locking mechanism 400 includes a fixed seat 401. The bottom of the inner wall of the work box 102 is provided with a fixed seat 401. The inner wall of the fixed seat 401 is provided with two sets of rotating grooves. The inner walls of the two sets of rotating grooves are rotatably connected to rotating rods 402. The outer walls of the two sets of rotating rods 402 are provided with torsion springs, and the other end of the torsion springs is connected to the inner wall of the rotating grooves. The bottom of the sliding plate 204 is provided with a mounting shaft 403. The bottom of the mounting shaft 403 is provided with a sliding shaft 404. The bottom of the sliding shaft 404 is provided with a locking block 405. The outer wall of the sliding shaft 404 is slidably fitted with a slip ring 406, and the diameter of the slip ring 406 is larger than the diameter of the locking block 405. The bottom of the inner wall of the work box 102 is provided with a return spring, and the other end of the return spring is connected to the bottom of the sliding plate 204.

[0042] When the sliding plate 204 moves downwards until the support leg 302 and solar panel 201 are fully opened, the sliding plate 204 drives the mounting shaft 403 into the mounting base. At this time, the locking block 405 moves to the bottom of the rotating rod 402. Due to the slope of the rotating rod 402, the locking block 405 can squeeze the rotating rod 402 into the rotating groove when it moves downwards. When the locking block 405 moves to the bottom of the rotating rod 402, the interface of the rotating rod 402 is reset by the torsion spring and rotates to the top of the locking block 405, blocking the locking block 405. At this time, the sliding plate... 204 is fixed in place and cannot move upwards. The return spring prevents the locking block 405 from falling downwards. This means the solar panel 201 and support leg 302 are fixed and cannot be rotated. Simultaneously, the threaded sleeve 210 moves to the bottom of the threaded rod 209 and separates from it. At this point, the motor 208 and threaded rod 209 can be removed, facilitating the subsequent retraction of the solar panel 201 and support leg 302. To move the locking block 405 out of the fixed base 401, simply continue pressing the sliding plate downwards. 204. The sliding plate 204 can drive the mounting shaft 403 to move downwards. The mounting shaft 403 drives the sliding shaft 404 to move downwards. The sliding shaft 404 drives the slip ring 406 to move downwards. At the same time, the rotating rod 402 will drive the slip ring 406 to move upwards. When the top end of the slip ring 406 is in contact with the bottom end of the mounting shaft 403 and cannot move upwards, the rotating rod 402 will be squeezed into the rotating groove by the slip ring 406. When the bottom end of the slip ring 406 moves below the rotating rod 402, the rotating rod 402 can be reset by the torsion spring and abut against the slip ring 406. When the inclined surface of 06 is stopped, the downward pressing of the mounting shaft 403 is stopped, and the return spring can drive the sliding plate 204 to move upward and reset. At this time, the rotating plate pushes the sliding ring 406 downward through the inclined surface of the sliding ring 406. When the bottom end of the sliding ring 406 is in contact with the top end of the locking block 405 and cannot move upward, the rotating rod 402 will be squeezed into the rotating groove due to the inclined surface of the sliding ring 406. At this time, the locking block 405 can move out of the mounting seat. When the return spring drives the sliding plate 204 to reset, the support leg 302 and the solar panel 201 are simultaneously retracted and reset.

[0043] Please refer to this carefully. Figure 1-6The outer wall of the working box 102 is provided with a protective mechanism 500, which includes a first damper 501. Multiple sets of first dampers 501 are provided on both ends of the outer wall of the working box 102. The output end of the multiple sets of first dampers 501 is provided with an arc-shaped baffle 502. Multiple sets of first shock-absorbing springs are provided on the side walls of the two sets of arc-shaped baffles 502, and the other end of the multiple sets of first shock-absorbing springs is connected to the outer wall of the working box 102. The outer walls of the other two ends of the working box 102 are provided with second dampers 503. The output end of the two sets of second dampers 503 is provided with a side baffle 504. The side walls of the two sets of side baffles 504 are provided with second return springs, and the other end of the second return springs is connected to the outer wall of the working box 102. The outer walls of the two sets of side baffles 504 are provided with two sets of push rods 505, and the two sets of push rods 505 fit with the outer wall of the arc-shaped baffle 502.

[0044] When an external object impacts the device, it will first be blocked by the arc-shaped baffle 502 or the side baffle 504. The impact force can be effectively damped by the first damper 501, the second damper 503, and the shock-absorbing spring, preventing damage to the main body of the device 100. At the same time, when the arc-shaped baffle 502 is impacted, the side wall of the arc-shaped baffle 502 will push the bottom end of the solar panel 201 to rotate. The rotation of the solar panel 201 will drive the sliding plate 204 to move downward, which will release the locking state of the fixed seat 401 and the mounting shaft 403. At this time, the reset spring can drive the sliding plate 204 to reset, and the solar panel 201 and the support leg 302 can automatically reset and retract, preventing damage to the solar panel 201 or the support leg 302 caused by the impact of external objects.

[0045] When in use, the solar panel 201 flips upwards with its sun-receiving surface facing the work box 102 when the main body 100 is not in use, preventing damage from collisions. When the main body 100 needs to be used, simply start the motor 208 to move the sliding plate 204 downwards, which in turn causes the solar panel 201 to flip downwards and open via the first connecting rod 202. When the sliding plate 204 moves downwards and causes the solar panel 201 to flip downwards, it also causes the two sets of support legs 302 to automatically flip downwards, thereby lifting the entire device upwards and allowing the casters 103 to leave the ground, improving the stability of the main body 100 during use. When the sliding plate 204 moves downwards to fully open the support legs 302 and the solar panel 201, the locking block 405 moves precisely below the rotating rod 402. At this time, the sliding plate 201... 4. When the device is fixed in place and cannot move upwards, the solar panel 201 and the support leg 302 are fixed in place and cannot be rotated. At the same time, the threaded sleeve 210 moves to the bottom of the threaded rod 209 and separates from the threaded rod 209. At this time, the motor 208 and the threaded rod 209 can be disassembled. When an external object hits the device, it will be blocked by the arc-shaped baffle 502 or the side baffle 504. The first damper 501, the second damper 503 and the shock-absorbing spring can effectively dampen the impact force and prevent damage to the main body 100 of the device. At the same time, when the arc-shaped baffle 502 is hit, the side wall of the arc-shaped baffle 502 will contact the bottom of the solar panel 201. At this time, the solar panel 201 and the support leg 302 can automatically reset and retract, preventing damage to the solar panel 201 or the support leg 302 caused by the impact of external objects.
