Description

Technical Field

[0001] The utility model belongs to the technical field of traffic safety warning equipment, and in particular relates to an electro-optical induction road sign for a highway. Background Art

[0002] Electro-optical induction road signs are traffic signs made using electro-optical technology and LED light sources. They are used to guide vehicles and remind drivers to pay attention to traffic safety. This type of road sign is usually installed on the road. It has the characteristics of high brightness, high visibility and durability. It can be clearly displayed at night or in bad weather conditions, playing the role of guidance, warning and reminder.

[0003] In the prior art, electro-optical induction road signs used to display road contours are usually installed at intervals along the road contours, and guide vehicles to drive safely by means of constant lighting or intermittent flashing. The constant lighting method of the road signs is relatively simple, which cannot give drivers greater visual stimulation and has a poor induction effect. The intermittent flashing method requires an additional controller, which is more expensive. In addition, the frequent opening and closing of the lamp body in the road sign and the current changes will cause a greater operating load on the lamp body, resulting in a reduced service life of the lamp body.

[0004] To this end, we propose a highway electro-optical induced road sign to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that the induction effect of the electro-optical induction road sign in the prior art is not good, and proposes an electro-optical induction road sign for a highway.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An electro-optical induction road sign for a highway comprises a base, a mounting tube is mounted on the base, a mounting plate is fixedly mounted on the mounting tube, a lamp holder is rotatably mounted at the center of the mounting plate, a lamp body is detachably mounted on the lamp holder, a conductive structure is arranged between the lamp holder and the mounting tube, and a motor is installed in the mounting tube and fixed coaxially with the lamp holder;

[0008] A plurality of vertical poles are evenly distributed on the periphery of the mounting plate, and the tops of the plurality of vertical poles are fixedly connected to the same top plate. A lampshade with a light-transmitting opening on the outer peripheral surface is rotatably arranged between the mounting plate and the top plate, the lamp body is located inside the lampshade, and a reverse transmission mechanism is arranged between the lampshade and the lamp holder.

[0009] Preferably, a spiral interface is provided on the lamp holder, and a spiral joint is provided at the bottom of the lamp body, and the spiral interface is adapted to the spiral joint.

[0010] Preferably, the conductive structure includes two contact rings fixed on the lamp holder, the two contact rings are axially spaced and electrically connected to the positive and negative pole wiring of the spiral interface in the lamp holder respectively, and the inner wall of the mounting tube is provided with two annular grooves adapted to the contact rings, and contact patches are arranged in the annular grooves, and the two contact patches are respectively connected to the positive and negative pole wires.

[0011] Preferably, a solar panel is installed on the top plate, and the positive and negative wires are electrically connected to the solar panel.

[0012] Preferably, the reverse transmission mechanism comprises an outer gear ring fixedly arranged on the outer circumference of the lamp holder, an inner gear ring is installed on the inner wall of the lampshade, and a plurality of gears are rotatably arranged on the mounting plate, and the gears are respectively meshed and connected with the outer gear ring and the inner gear ring.

[0013] Preferably, the light-transmitting opening is in the shape of a laterally arranged arrow, and the rotation direction of the lampshade is opposite to the direction of the arrow of the light-transmitting opening.

[0014] Preferably, the lamp body has a longitudinal strip-shaped light-emitting portion, and the lateral projection height of the light-transmitting opening is smaller than the height of the light-emitting portion.

[0015] Preferably, the side wall of the vertical pole is provided with a scraper, and the scraper is in contact with the outer peripheral surface of the lampshade.

[0016] To sum up, the technical effects and advantages of the utility model are as follows: the electro-optical induced road sign of the highway, through the reverse rotation of the lamp holder and the lampshade, uses the light-transmitting opening to transmit bright light, and when the lampshade and the lamp body rotate relatively, an intermittent flashing effect is displayed at the light-transmitting opening, thereby improving the driving safety of vehicles.

[0017] By setting an arrow-shaped light-transmitting opening, when the lampshade rotates, the light emitted by the lamp body is emitted at the position of the light-transmitting opening, so that the arrow shape of the light-transmitting opening appears to have a flowing dynamic guidance effect. Compared with traditional static road signs, it has greater visual stimulation for drivers and is conducive to improving the guidance effect.

[0018] By means of the scraper strips arranged on the side of the vertical pole, the surface of the lampshade is decontaminated when the lampshade rotates, so as to keep the surface of the lampshade clean and reduce the influence of the stains on the lighting display effect.

A spiral interface is provided on the lamp holder 4, and a spiral joint is provided at the bottom of the lamp body 5. The spiral interface is adapted to the spiral joint. The spiral interface and the spiral joint are national standard interfaces commonly used in lamps. The lamp body 5 is an LED lamp, which is convenient for the installation and replacement of the lamp body 5. A conductive structure is provided between the lamp holder 4 and the mounting tube 2. A motor 8 coaxially fixed with the lamp holder 4 is installed in the mounting tube 2. The motor 8 can drive the lamp holder 4 to rotate, and under the action of the conductive structure, the lamp holder 4 is always powered on when rotating.

[0029] Reference Figure 3-4The conductive structure includes two contact rings 41 fixed on the lamp holder 4. The two contact rings 41 are axially spaced and electrically connected to the positive and negative wiring of the spiral interface in the lamp holder 4 respectively. The inner wall of the mounting tube 2 is provided with two annular grooves 21 adapted to the contact rings 41. The annular grooves 21 cooperate with the contact rings 41 to limit the axial position of the lamp holder 4 to ensure that the axial displacement does not occur when the lamp holder 4 rotates. A contact patch 22 is arranged in the annular groove 21. The contact ring 41 and the contact patch 22 are abutted against each other to achieve electrical connection, and the electrical connection is always maintained when the lamp holder 4 rotates. State, two contact patches 22 are respectively connected to the positive and negative wires, a solar panel 61 is installed on the top plate 6, the positive and negative wires are electrically connected to the solar panel 61, the solar panel 61 is a prior art, including a photovoltaic panel and a battery, which will not be described in detail here, the solar panel 61 converts light energy into electrical energy and stores it, and then introduces it into the contact patch 22 to supply power to the lamp holder 4, so that the lamp body 5 emits light, and the conductive structure can keep the lamp holder 4 in a rotating state to provide power input to the lamp body 5, so as to avoid the entanglement of the wires caused by the rotation of the lamp holder 4 when the wires are directly connected.

[0030] A plurality of vertical poles 31 are evenly distributed on the periphery of the mounting plate 3, and the tops of the plurality of vertical poles 31 are fixedly connected to the same top plate 6. A lampshade 7 with a light-transmitting opening 71 on the outer peripheral surface is rotatably arranged between the mounting plate 3 and the top plate 6. The lampshade 7 is made of acrylic material, and the light-transmitting opening 71 is partially made of transparent material. Except for the light-transmitting opening 71, the remaining parts are made of dark-colored light-shielding material. The lamp body 5 is located inside the lampshade 7, and the lamp body 5 is wrapped in a closed space to prevent rainwater and mosquitoes from entering. A reverse transmission mechanism is arranged between the lampshade 7 and the lamp holder 4. When the motor 8 drives the lamp holder 4 to rotate, the lampshade 7 is driven to rotate in the reverse direction under the action of the one-way transmission mechanism, so that the lamp body 5 and the lampshade 7 rotate in the reverse direction, and bright light is transmitted through the light-transmitting opening 71. When the lampshade 7 and the lamp body 5 rotate relatively, an intermittent flashing effect is displayed at the light-transmitting opening 71, thereby improving the driving safety of the vehicle.

[0031] Reference Figure 2 , 5 and 6, the light-transmitting opening 71 is shaped like a laterally arranged arrow, and the rotation direction of the lampshade 7 is opposite to the arrow direction of the light-transmitting opening 71, the lamp body 5 has a longitudinal strip-shaped light-emitting portion 51, the lateral projection height of the light-transmitting opening 71 is less than the height of the light-emitting portion 51, when the lampshade 7 rotates in the direction opposite to the arrow, the relative rotation direction of the lamp body 5 and the lampshade 7 is consistent with the arrow direction, at this time the light-emitting portion 51 will move from the arrow end of the light-transmitting opening 71 to the arrow front end, what the driver sees from the perspective of the light-transmitting opening 71 is a flowing dynamic guidance effect that changes along the arrow direction, which has a greater visual stimulation to the driver than traditional static road signs and is beneficial to improving the guidance effect.

[0032] When the induction road sign is installed in the middle isolation zone of a two-way lane, since the light-transmitting openings 71 are distributed circumferentially around the lampshade 7, the arrow directions of the light-transmitting openings 71 observed on opposite sides of the lampshade 7 are opposite, so vehicles in both lanes can be guided and instructed to drive at the same time.

[0033] Reference Figure 2-4 and 6, the reverse transmission mechanism includes an outer gear ring 42 fixedly arranged on the outer peripheral surface of the lamp holder 4, an inner gear ring 72 is installed on the inner wall of the lamp cover 7, and a plurality of gears 32 are rotatably arranged on the mounting plate 3, and the gears 32 are respectively meshed and connected with the outer gear ring 42 and the inner gear ring 72. When the lamp holder 4 rotates under the drive of the motor 8, the outer gear ring 42 drives the gear 32 to rotate, and further drives the inner gear ring 72 to rotate, so that the lamp holder 4 and the lamp cover 7 rotate in the opposite direction.

[0034] Reference Figure 1-3 A scraper strip 33 is provided on the side wall of the vertical rod 31, and the scraper strip 33 is in contact with the outer peripheral surface of the lampshade 7. When the lampshade 7 rotates, the scraper strip 33 continuously removes dirt from the surface of the lampshade 7, thereby reducing the influence of the dirt on the light display effect.

[0035] Working principle:

[0036] The induction road signs are installed at intervals along the road, and two-way lanes can be installed on the isolation strip in the middle of the lanes. The motor 8 and the lamp body 5 are powered by the solar panel 61, so that the light-emitting part 51 on the lamp body 5 emits light. At the same time, the motor 8 drives the lamp holder 4 to rotate. When the lamp holder 4 rotates under the drive of the motor 8, the outer gear ring 42 drives the gear 32 to rotate, and further drives the inner gear ring 72 to rotate, so that the lamp holder 4 and the lamp cover 7 rotate in the opposite direction.

[0037] The lampshade 7 rotates in the direction opposite to the arrow, and the relative rotation direction of the lamp body 5 and the lampshade 7 is consistent with the direction of the arrow. At this time, the light-emitting portion 51 will move from the arrow end of the light-transmitting opening 71 to the arrow front end. From the driver's perspective, what is seen is a flowing dynamic guidance effect that changes along the arrow direction in the light-transmitting opening 71, which has a greater visual stimulation to the driver and is conducive to improving the guidance effect.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
