Description

Technical Field

[0001] The utility model belongs to the technical field of traffic signs, in particular to an intelligent traffic sign. Background Art

[0002] As an important part of modern urban traffic management and safety control, intelligent traffic signs can effectively improve the efficiency of traffic information transmission and the management level of traffic safety through the integration of advanced technology and innovative design. These signs are not just a simple substitute for traditional signs, but also a new type of equipment that combines digitalization, intelligence and sustainable development concepts.

[0003] After searching, the existing patent (Announcement No.: CN 217997871 U) discloses an intelligent urban traffic guide sign, including a bracket, a C-shaped sign installed on the top of the bracket, the C-shaped sign includes a main sign and side signs arranged on both sides of the main sign, the front surface of the main sign is provided with a main single-line text area arranged side by side, one end of the main single-line text area is provided with a graphic guide arrow, the front of the side sign is provided with a side single-line text area arranged side by side, the side single-line text area corresponds to the position of the main single-line text area, and one end of the side single-line text area is provided with a physical arrow, and the graphic guide arrows and the physical arrows in the same row point to the same direction. The utility model sets the sign into a C shape, which ensures that the main sign facing the driver and the side sign located on the side of the driver have the same marking information on the main sign and the side sign, so that the driver can still observe the marking information on the side sign after missing the information on the main sign.

[0004] However, in actual use, the above solution is a fixed design. Although fixed traffic signs are beneficial to traffic management and safety, for large-scale transportation, such as height and width limit signs, they will limit the routes that large-scale goods can choose. This may cause the transport personnel to take a detour or choose a longer route, increasing the transportation distance and time cost.

[0005] To this end, the utility model provides an intelligent traffic sign. Utility Model Content

[0006] In order to make up for the shortcomings of the prior art and solve the problem that fixed traffic signs will limit the routes that large goods can choose, which may cause the transport personnel to take a detour or choose a longer route, increasing the transportation distance and time cost, the utility model proposes an intelligent traffic sign.

[0007] The technical solution adopted by the utility model to solve its technical problems is: the intelligent traffic sign described in the utility model comprises a limit sleeve, the bottom end of the limit sleeve is fixedly connected to a second motor, the output end of the second motor is fixedly connected to a third screw rod, the outer side of the middle end of the third screw rod is threadedly connected to a third threaded sleeve, the outer top end of the third threaded sleeve is fixedly connected to a sliding sleeve, the outer side of the top end of the third screw rod is rotatably connected to a limit plate, the outer bottom end of the limit plate is slidably connected to left and right opposite limit rods, the limit rod is fixedly connected to the second motor, and a folding component is arranged on the inner side of the top end of the sliding sleeve;

[0008] Through the above technical solution, the third threaded sleeve is driven to rise and fall by the second motor using the third screw rod, thereby driving the sliding sleeve to operate. At the same time, the third threaded sleeve is limited by the left and right relative limiting rods, so that the third threaded sleeve can only move up and down but cannot rotate, thereby realizing the contraction of the sliding sleeve.

[0009] Further, the folding assembly includes a first screw rod, a fixed block opposite to the upper and lower parts is fixedly connected to the left inner part of the top of the sliding sleeve, the inner side of the fixed block is rotatably connected to the first screw rod, the outer side of the top of the first screw rod is rotatably connected to the first fixed frame, the outer side of the bottom end of the first screw rod is rotatably connected to the fourth fixed frame, the fourth fixed frame is fixedly connected to the bottom fixed block, the bottom end of the fixed block is fixedly connected to the first motor, the output end of the first motor is fixedly connected to the first screw rod, and the outer side of the middle end of the first screw rod is connected to the first threaded sleeve through a screw nut pair;

[0010] Through the above technical solution, the first motor drives the left bottom end of the articulated frame to rise and fall, and limits the left top end, thereby controlling the extension and retraction of the articulated frame, and driving the right mechanism to move horizontally through the articulated frame.

[0011] Further, the right outer end of the first threaded sleeve is rotatably connected to an articulated frame, the left side of the top end of the articulated frame is rotatably connected to the first fixed frame, the right bottom end of the articulated frame is externally rotatably connected to a second threaded sleeve, the second threaded sleeve is connected to the second screw rod through a screw nut pair, the right top end of the articulated frame is rotatably connected to a second fixed frame, the second fixed frame is rotatably connected to the second screw rod, the outer side of the bottom end of the second screw rod is rotatably connected to a third fixed frame, the right outer wall of the third fixed frame is fixedly connected to a sealing plate, and the sealing plate is fixedly connected to the second fixed frame;

[0012] Through the above technical solution, the second threaded sleeve at the right bottom end of the hinged frame drives the second screw rod to rotate through the screw nut pair, thereby reducing the friction between the second threaded sleeve and the second screw rod.

[0013] Furthermore, the top end of the second screw rod is fixedly connected to a first gear, the outer side of the first gear is meshedly connected to a transmission chain, the inner side of the front end of the transmission chain is meshedly connected to a second gear, the bottom end of the second gear is fixedly connected to a winding rod, and the outer side of the winding rod is fixedly connected to a road sign;

[0014] Through the above technical solution, the second screw rod drives the first gear to rotate, and the first gear drives the second gear and the winding rod to rotate synchronously through the transmission chain, so that when the articulated frame is extended, the second screw rod is driven by the second threaded sleeve to rotate forward, and when it is retracted, it is reversed, so that the road sign is rolled up.

[0015] Furthermore, a fixing rod is fixedly connected to the inner side of the front end of the fourth fixing frame, the fixing rod is fixedly connected to the first fixing frame, and the fixing rod is fixedly connected to the road sign;

[0016] Through the above technical solution, the left end of the road sign is fixed by the fixing rod.

[0017] Furthermore, a sealing seat is fixedly connected to the outer side of the top end of the limiting sleeve;

[0018] Through the above technical solution, the inner space of the limiting sleeve is sealed by the sealing seat to prevent soil or dust from entering the inside of the limiting sleeve and affecting the normal operation of the equipment.

[0019] The beneficial effects of the utility model are as follows:

[0020] 1. The utility model describes an intelligent traffic sign, which uses a second motor to use a third screw rod to drive the third threaded sleeve to rise and fall, thereby driving the sliding sleeve to operate, and at the same time, the third threaded sleeve is limited by the left and right relative limit rods, so that the third threaded sleeve can only move up and down but cannot rotate. At the same time, by cooperating with the folding component, the sliding sleeve can be retracted as a whole into the underground limit sleeve to avoid affecting the passability when a large transport vehicle passes by.

[0021] 2. The intelligent traffic sign described in the utility model realizes automatic folding and releasing of the road sign by synchronously rotating the reeling rod following the extension and retraction of the articulated frame, without the need for human intervention, thus improving the automation of the device and saving time and effort.
