Description

Technical Field

[0001] The present invention relates to the technical field of traffic lights, and more specifically, to an integrated assembled traffic light. Background Art

[0002] Traffic lights can orderly guide vehicles and pedestrians through intersections, avoid traffic congestion, and improve the traffic capacity of roads. The guiding and controlling functions of traffic lights help reduce the occurrence of traffic accidents, especially in busy intersections and crowded areas, providing strong guarantee for the safe and orderly operation of urban traffic.

[0003] When installing traditional traffic lights, a large number of bolts are often required to fix various components, such as boxes, panels, lamp head units, etc. Moreover, there is a lack of precise positioning structure during installation, which makes it necessary to repeatedly adjust the position during installation to ensure that all components are correctly aligned. This not only increases the installation difficulty and time, but also easily leads to errors during the installation process. When it is necessary to repair or replace components, the disassembly process is also cumbersome and time-consuming. In addition, most existing traffic lights lack a self-detection mechanism and cannot detect the working status of key components such as internal circuit boards and LED lamp beads. Faults are often detected by manual inspection or after receiving user reports, and it may not be possible to quickly and accurately determine the specific location of the fault, which may lead to untimely fault handling and affect traffic order. Summary of the Invention

[0004] The present invention aims to overcome the defects of the prior art and provides an integrated assembled traffic light.

[0005] To achieve the above object, the present invention provides the following technical solution: A traffic light includes a box, a panel, and three lamp head units. There are two partitions in the box to divide the space in the box into three installation spaces. The lamp head unit includes a housing, a light-emitting unit, and a cover unit. The light-emitting unit includes a circuit board and a plurality of LED lamp beads mounted on the circuit board; there are three circular through-holes at the panel, and a circular mounting plate is fixedly connected at the circular through-holes. A circular transparent plate is mounted at the circular mounting plate, and each circular transparent plate faces a lamp head unit. The panel is fixedly connected to the box.

[0006] Further, the circular mounting plate and the circular transparent plate are fixedly connected by an adhesive.

[0007] Thus, the circular transparent plate is firmly installed and forms protection for the internal lamp head unit.

[0008] Further, a pressing unit and a plug post are installed in the installation space. The pressing unit includes a first surrounding ring fixedly connected to the box body, an annular abutting plate capable of abutting against the housing, a circular block fixedly connected to the annular abutting plate, a second surrounding ring fixedly connected to the circular block, and a first spring connecting the box body and the circular block. One end of the first spring is surrounded by the first surrounding ring, and the other end is surrounded by the second surrounding ring; a first cylindrical protruding shell and a second cylindrical protruding shell are connected to the back of the housing. The first cylindrical protruding shell can be inserted into the annular abutting plate, and the second cylindrical protruding shell has a jack into which the plug post can be inserted.

[0009] Thus, the back of the lamp head unit is abutted by the pressing unit, making the installation of the lamp head unit more stable.

[0010] Further, the first cylindrical protruding shell has a wire passing hole.

[0011] Thus, it is convenient for the circuit board to route wires.

[0012] Further, the housing includes a frustum-shaped shell and a circular frame connected to the frustum-shaped shell. A plurality of positioning and mounting parts are connected to the frustum-shaped shell. The positioning and mounting parts include a positioning block, a clamping plate connected to the positioning block, two end abutting plates respectively fixed on both sides of the clamping plate, and two arc-shaped plates respectively fixed on both sides of the clamping plate. The circuit board is circular and has a plurality of slots at the circumference into which the clamping plate can be inserted. The end abutting plates can abut against the circuit board, and the positioning block has a positioning hole; the cover plate unit includes a transparent circular cover plate, a circumferential plate connected to the circular cover plate, an annular substrate fixed to the circumferential plate, a plurality of abutting blocks fixed to the annular substrate and capable of abutting against the circuit board, and a plurality of positioning posts fixed to the annular substrate and cooperating with the positioning holes.

[0013] Further, both the annular substrate and the annular mounting plate are circular rings.

[0014] Further, the end of the positioning block close to the cover plate unit is flush with the end of the frustum-shaped shell. A first annular sealing gasket capable of abutting against the end of the frustum-shaped shell is also installed on the annular substrate; a second annular sealing gasket capable of abutting against the annular substrate is installed on the annular mounting plate.

[0015] Thus, the sealing performance inside the lamp head unit is good, and the sealing performance between the lamp head unit and the panel is better, and the installation is stable.

[0016] Further, a rotating ring plate is installed inside the housing. The inner circumference of the rotating ring plate has a circle of teeth. A driving motor is installed inside the second cylindrical protruding housing. The driving motor drives a gear that meshes with the circle of teeth. Eight cylindrical parts with one end open are fixed inside the housing. The cylindrical parts have embedding grooves into which the rotating ring plate is embedded. There are mounting grooves at the rotating ring plate, and light intensity sensors are installed in the mounting grooves. Driven by the driving motor, the light intensity sensors can rotate into all the cylindrical parts. Four reflecting plates evenly distributed at equal intervals in a ring shape are installed at the cover plate unit. The angle formed by each reflecting plate and the axis of the cover plate unit is 45 degrees. There are 8 through-hole parts at the circuit board. The 8 through-hole parts correspond to the 8 cylindrical parts one by one. Each through-hole part faces a cylindrical part. Four of the four reflecting plates correspond to four of the 8 through-hole parts one by one. Each reflecting plate faces a through-hole part.

[0017] Further, among the four reflecting plates, the connection line of two of the reflecting plates is in the vertical direction, and the connection line of the other two reflecting plates is in the horizontal direction.

[0018] Further, a butting ring plate is also installed at the circuit board. A pressure detection unit is installed at the rotating ring plate. The pressure detection unit includes a regular hexagonal column fixedly connected to the rotating ring plate, a movable tube inserted by the regular hexagonal column and capable of relatively moving with respect to the regular hexagonal column, a traveling wheel installed at the end of the movable tube and capable of butting against the butting ring plate, an end ring plate fixed to the end of the movable tube, a movable ring plate fixedly connected to the end ring plate through a second spring, a connecting plate connected to the movable ring plate, a pressing block connected to the connecting plate, and a pressure sensor installed on the rotating ring plate. The pressing block can press the pressure sensor.

[0019] Further, the outer diameter of the circuit board is equal to the inner diameter of the arc-shaped plate. The arc-shaped plate is connected to both the clamping plate and the end butting plate.

[0020] Thus, the arc-shaped plate can limit the circuit board in the circumferential direction.

[0021] Further, there are 8 positioning and installation parts, abutting blocks, and positioning columns, and they are all evenly distributed at equal intervals in a ring shape.

[0022] Further, the box body is connected with a rectangular frame-shaped frame part. The frame part has a plurality of threaded holes. The panel is fixedly connected to the box body through bolts. Two rectangular sealing frames are installed at the frame part.

[0023] Thus, the sealing performance between the panel and the box body is better, and the installation is stable.

[0024] Further, there are 3 wire routing holes on the box body, which are respectively communicated with 3 installation spaces; a back box body with an open bottom end is fixedly connected to the back of the box body, and all the wire routing holes are communicated with the back box body. The back box body is connected with a control box body, and a controller and a wireless communication unit are installed in the control box body.

[0025] This facilitates the wire routing of each lamp head unit, as well as the remote communication and control of the signal lamp.

[0026] Further, both the top end and the bottom end of the box body are provided with end grooves, and connecting blocks are fixed in the end grooves. The connecting blocks are connected with connecting columns.

[0027] This facilitates the installation and fixation of the signal lamp.

[0028] Further, a liquid leakage hole is provided at the end groove at the top end.

[0029] This avoids liquid accumulation.

[0030] Beneficial effects:

[0031] 1. The traffic signal lamp of the present application can realize the installation through the cooperation of the card slot, the card board, the positioning hole and the positioning column, and uses fewer bolts for fixation. The assembly and fixation of each component can be realized only through the bolts at the panel, so that the installation and disassembly of the signal lamp are more convenient.

[0032] 2. The traffic signal lamp of the present application can detect whether the internal circuit board is correctly installed and whether there are installation faults, ensuring the correct installation of the components inside the box body.

[0033] 3. The traffic signal lamp of the present application can detect whether the LED lamp beads on the circuit board are working normally, so as to ensure the normal operation of the signal lamp. Description of the drawings

The arc-shaped plate 7.4 is connected to both the clamping plate 7.2 and the end butting plate 7.3. There are 8 positioning and installation parts, abutting blocks 5.4, and positioning columns 5.5, and they are all distributed at equal intervals in a ring shape. The box body 1 is connected with a rectangular frame-shaped frame part. The frame part has a plurality of threaded holes 1.3. The panel 2 is fixedly connected to the box body 1 through bolts 2.5. Two rectangular sealing frames 1.4 are installed at the frame part. The box body 1 has 3 wire passing holes 1.5 respectively communicating with 3 installation spaces. The back of the box body 1 is fixedly connected with a back box body 9 with an open bottom end. All the wire passing holes communicate with the back box body. The back box body is connected with a control box body 10. A controller and a wireless communication unit are installed inside the control box body.

[0050] Working principle: As shown in the figure, when the signal lamp of the present application is installed, it is mostly positioned by means of positioning posts, positioning holes, card slots, and card plates, and finally the box body and the panel are fixedly connected by bolts at the panel, while completing the installation and positioning of the lamp head units in each installation space. The installation is more convenient, without excessive installation and disassembly of bolts, thus realizing convenient installation, disassembly and maintenance. The back of the lamp head unit is abutted by the abutting unit, and the abutting unit has a first spring, so as to achieve better abutment of the lamp head unit, and the cooperation of the plug post and the jack makes the installation angle positioning of the lamp head unit more convenient during installation. And after installation, due to the sealing of the first annular gasket and the second annular gasket, as well as the sealing of the two rectangular sealing frames, a better sealing effect is achieved for the internal circuit board of the lamp head unit. The circular transparent plate at the panel forms an integral body with the panel, thus providing better protection for the internal lamp head unit.

[0051] In addition, for the signal lamp of the present application, since its internal structure mostly uses the cooperation of positioning posts, positioning holes, card slots, and card plates for positioning, while simplifying installation and disassembly, if the internal components are not accurately engaged, or the positioning engagement falls off due to external forces or other reasons, it will cause inaccurate and unstable installation of components such as the internal circuit board, resulting in the signal lamp being unable to work properly. Therefore, a self-detecting device is designed. As shown in the figure, the driving motor drives the gear, which in turn drives the rotating circular ring plate to rotate. The embedding groove at the cylindrical part actually plays a role in limiting and positioning. As the rotating circular ring plate rotates, the walking wheel will walk around the annular abutting plate. When the circuit board is accurately installed and positioned, when the walking wheel walks around, the measured values of the pressure sensor are almost equal, thereby determining that the circuit board is accurately installed; otherwise, it is determined that there is an installation fault with the circuit board. In addition, the detecting device can also simultaneously detect whether the LED lamp beads at the circuit board are normally lit. As shown in the figure, the connection lines of two of the four reflector plates are in a horizontal state, and the connection lines of the other two are in a vertical state. For example, when the light intensity sensor is located in the bottommost cylindrical part, the light emitted by some LED lamp beads will irradiate the uppermost reflector plate, be reflected by the uppermost reflector plate to the lowermost reflector plate, be reflected by the lowermost reflector plate, pass through the through-hole part at the bottom, and be received and detected by the light intensity sensor, and the detected brightness reaches above the set threshold. The role of the cylindrical part is, on the one hand, to position the rotating circular ring plate, and on the other hand, to enable the light intensity sensor to be located inside the cylindrical part for detection, so that the measured value of the light intensity sensor is more affected by the light reflected by the reflector plate and passing through the cylindrical part, reducing the influence of ambient light. And theoretically, when the light intensity sensor is located at the positions of the cylindrical parts corresponding to the four reflector plates, the measured values are larger and almost equal. When the light intensity sensor is located at the positions of the other four cylindrical parts, since there is no reflection of the light from the reflector plate at this time (but there will still be a small amount of light reflected by the transparent circular cover plate and detected by the light intensity sensor through the through-hole part), the measured values of the light intensity sensor at these four positions are roughly equal, but much smaller than the measured values of the light intensity sensor at the other four positions. Thus, by measuring the light intensity at multiple positions, it can be determined whether the circuit board is working properly, and it can also detect whether some LED lamp beads at the circuit board are damaged (when some LED lamp beads at the circuit board are damaged, the measured values of the light intensity sensor are different at different cylindrical part positions in the same category (i.e., one category facing the reflector plate and the other category not facing the reflector plate)). The detection steps can be executed regularly, for example, once an hour or once a day.

[0052] Although the present invention has been illustrated and described with respect to preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
