Description

Technical Field

[0001] The present invention relates to the technical field of traffic signal lamps, and more specifically, to a modular and conveniently maintainable traffic signal lamp. Background Art

[0002] With the acceleration of urbanization and the increase in traffic flow, traffic lights have become an important tool to ensure the orderly, safe and efficient operation of road traffic. Traffic lights can effectively guide and control vehicles and pedestrians, reduce traffic congestion and traffic accidents, and improve road use efficiency.

[0003] The information displayed on the lamp head of existing traffic lights is relatively simple. For example, the cylindrical lamp usually displays the traffic light signal, but cannot display the arrow light signal, let alone the countdown signal. At the intersection where the vehicle needs to be clearly indicated to turn (such as left turn, right turn), the cylindrical lamp cannot provide enough visual information to guide the driver. The driver cannot accurately judge the remaining time when waiting for the traffic light, resulting in reduced traffic efficiency and may even increase the risk of traffic accidents. In addition, the lamp head of an existing traffic light is often regarded as a whole. Once the lamp head is damaged, it must be replaced as a whole, which not only increases the maintenance cost, but also may lead to unnecessary waste of resources. And the replacement and maintenance of the lamp head is relatively complicated. Summary of the invention

[0004] The present invention aims to overcome the defects of the prior art and provide a modular and easy-to-maintain traffic signal lamp.

[0013] Furthermore, the end seat has a first arc-shaped chamfer and a second planar chamfer, and the abutment plate has a third arc-shaped chamfer.

[0014] Therefore, when the rectangular display unit rotates, the end seat and the abutting seat abut against each other and move relative to each other. Due to the first chamfer and the third chamfer, the relative movement between the two is smoother.

[0015] Furthermore, a first motor is installed on the top plate, a first bearing is installed on the bottom plate, a first screw rod is connected between the first motor and the first bearing, a first lifting seat is installed on the first screw rod, a first guide rod passing through the first lifting seat is also connected between the top plate and the bottom plate, and an image acquisition unit is installed on the first lifting seat; the traffic light can be in a verification state, in which the second chamfers of the end seats of all the rectangular display units abut against the back plate, and the end seats of all the rectangular display units are abutted by the side of the side door, the first motor drives the first lifting seat to rise, and the image acquisition unit acquires images of the rectangular display units.

[0016] Specifically, the image acquisition unit moves upward from the bottom to acquire more than one image for each rectangular display unit.

[0017] In some embodiments, other ways of collecting images may also be used, such as collecting multiple photos or a video. When collecting photos and videos, the control unit may run a specific display program.

[0019] Furthermore, the second lifting seat can drive the spare rectangular display screen to move below the panel opening and be covered by the panel.

[0020] Furthermore, there are three mounting frames; each mounting frame has four plug-in positions.

[0021] Other numbers of mounting brackets may be selected as needed, and each mounting bracket may have other numbers of plug-in positions.

[0022] Furthermore, a first locking portion is provided between the side door and the box body; a rectangular frame portion surrounding the side opening is fixed to the second side panel of the opening side panel unit, a shielding door is hingedly installed on the rectangular frame portion, and a second locking portion is provided between the shielding door and the rectangular frame portion.

[0050] There are three mounting frames 3; each mounting frame 3 has four plug-in positions. A first lock portion is provided between the side door 2 and the box body 1; a rectangular frame portion 6.2 surrounding the side opening is fixed to the second side plate 1.5 of the opening side plate unit 6, a shielding door 10 is hingedly installed on the rectangular frame portion 6.2, and a second lock portion is provided between the shielding door 10 and the rectangular frame portion 6.2.

[0051] Working principle: In the traffic light of the present application, each signal indication unit is composed of multiple rectangular display units, so as to be a signal indication unit displayed as a whole, which has a large display area and can display different types of traffic indication signals. Different displays can be achieved by simply changing the software program as needed.

[0052] In normal use, the first lifting seat can drive the image acquisition unit to perform routine inspections up and down to determine whether the rectangular display unit is damaged. Since the image acquisition angle is limited at this time, alarm maintenance can be performed only when the rectangular display unit is obviously damaged. After the alarm maintenance, the background operator can also remotely observe the working condition of the rectangular display unit to determine whether on-site maintenance is required.

[0053] When receiving maintenance information, maintenance personnel go to the site, work at height, open the shielding door and the side door, so that the damaged rectangular display unit can be pulled out and a new rectangular display unit can be plugged in, so that maintenance can be quickly achieved. And after the replacement is completed, the traffic light can be put into the verification state. At this time, because the end seat abuts the back plate and is limited by the side of the side door, each rectangular display unit is accurately positioned, and the image acquisition unit has a good acquisition angle at this time, so that all rectangular display units can be checked through the image acquisition unit to determine whether all rectangular display units are qualified. After confirming that they are qualified, it is restored to the installation state. At this time, because the end seat is abutted and limited by the abutment seat, the installation is stable.

[0054] Normally, when the image acquisition unit determines a fault based on the image, since there is a time difference for the maintenance personnel to arrive at the site for maintenance, the spare rectangular display screen can be used to cover the damaged rectangular display unit, thereby achieving the normal operation of the indicator light unit as a whole. When the spare rectangular display screen rises, the first lifting seat first descends, and the lifting rod descends to the bottom of the straight rod, and then rises, so that the plug column is inserted into the socket, so that the first lifting seat and the second lifting seat lift the spare rectangular display screen from both ends, thereby lifting the spare rectangular display screen to the corresponding position. And after manually removing the damaged rectangular display unit and replacing the new rectangular display unit, manual assistance is required to make the lifting rod at the first lifting seat above the straight rod at the spare rectangular display screen, so that the image acquisition unit at the first lifting seat can be lifted and inspected normally.

[0055] Although the present invention has been illustrated and described with respect to the preferred embodiments, it will be appreciated by those skilled in the art that various changes and modifications may be made to the present invention without departing from the scope of the present invention as defined by the claims.
