Description

Technical Field

[0001] The present invention relates to the technical field of traffic signal lamps, and more specifically, to a multi-lamp-cap pedestrian traffic signal lamp. Background Art

[0002] With the rapid advancement of urbanization, traffic signals at road intersections have become increasingly complex and diverse. In order to meet the traffic needs of different intersections, traffic lights need to have higher flexibility and upgradeability. However, existing traffic lights do not have room for upgrades, which means that when it is necessary to add signal light heads, it is often very difficult. Even if some traffic lights have the possibility of upgrades, due to the lack of remote maintenance and upgrade capabilities, on-site maintenance and upgrades are required, which not only increases the workload of maintenance personnel, but may also cause unnecessary interference to traffic operations, making the upgrade operation more troublesome. Summary of the invention

[0003] The present invention aims to overcome the defects of the prior art and provide a multi-lamp-cap pedestrian traffic signal light.

[0004] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions: a traffic signal light, comprising a box body, a plurality of signal lamp heads and a plurality of sunshade units, the box body comprising a top plate, a bottom plate, a panel, a back plate and two side panel units, the side panel unit comprising an outer plate and an inner plate, a side panel inner space is formed between the outer plate and the inner plate, and a box inner space is formed between the inner plates of the two side panel units; the panel has a plurality of mounting positions, each mounting position is equipped with a first strip abutment block, a strip mounting block and a sunshade unit, each mounting position has two strip through grooves connected to the box inner space, the sunshade unit comprises two side baffles, a shielding plate connecting the two side baffles and a second strip abutment block fixedly connected to the shielding plate and capable of abutting against the first strip abutment block, the two side baffles are respectively inserted into the two strip through grooves of the corresponding mounting positions, the shielding plate is hinged to the strip mounting block by a first elastic reset hinge component, and when there is no external force, the shielding plate is parallel to the panel and shields the corresponding signal lamp head.

[0005] Furthermore, the inner panel is provided with a plurality of arc-shaped through grooves, and the number of the arc-shaped through grooves on each inner panel is equal to the number of mounting positions on the panel and the two correspond one to one; the outer panel is provided with a plurality of positioning holes, and the number of the positioning holes on each outer panel is equal to the number of mounting positions on the panel and the two correspond one to one; the side baffle is fixedly connected with a fixing column passing through the arc-shaped through groove, and the fixing column is covered with a movable sleeve, and the movable sleeve has a blind hole inserted by the fixing column, and a spring is connected between the end of the blind hole and the end of the fixing column, and the end of the movable sleeve can abut the outer panel and can be inserted into the positioning hole; the sunshade unit can be in a protection state and a sunshade state, in which the fixing column of the sunshade unit is located at the top of the arc-shaped through groove, and the movable sleeve abuts the outer panel; in the sunshade state, the fixing column of the sunshade unit is located at the bottom of the arc-shaped through groove, and the movable sleeve is inserted into the positioning hole.

[0006] Further, in the sunshade state, the second strip-shaped abutting block abuts against the first strip-shaped abutting block.

[0007] Furthermore, the end of the movable sleeve has an arc-shaped chamfer.

[0008] Furthermore, each side panel unit is equipped with a driving unit, which includes a driving motor, a screw bearing, a vertical guide rod, a screw connected between the driving motor and the screw bearing, a lifting block, and a driving plate hinged to the lifting block through a second elastic reset hinge component, the lifting block has a guide hole matched with the vertical guide rod and a threaded hole matched with the screw, the screw and the vertical guide rod are both located in the space inside the side panel; the second elastic reset hinge component makes the driving plate perpendicular to the panel when there is no external force; a surrounding protrusion is fixed to the movable sleeve, the surrounding protrusion has a circumferential surface and a frustum-shaped surface connected to the circumferential surface, and the A driving abutment block is fixed on the upper surface of the driving plate, and the driving abutment block has an abutment inclined surface that can abut against the frustum-shaped surface; when the sunshade unit is in a protection state, the driving plate passes through the corresponding installation position of the sunshade unit from top to bottom, and the driving plate can drive the fixed column to slide downward along the arc-shaped through groove until the movable sleeve is inserted into the positioning socket; when the sunshade unit is in a sunshade state, the driving plate passes through the corresponding installation position of the sunshade unit from bottom to top, and the driving abutment block at the driving plate can abut against the surrounding protrusion, so that the movable sleeve is disengaged from the positioning socket, and the fixed column can slide upward along the arc-shaped through groove until the shielding plate is parallel to the panel.

[0009] Furthermore, the elastic force of the second elastic reset hinge component is greater than the elastic force of the first elastic reset hinge component.

[0010] Therefore, a larger force is required to enable the driving plate to overcome the elastic force of the second elastic reset hinge component and rotate. Relatively speaking, a smaller force is required to enable the sunshade unit to overcome the elastic force of the first elastic reset hinge component and rotate.

[0011] Furthermore, there are five installation positions, which are distributed vertically with equal intervals.

[0040] The present invention provides a multi-lamp-holder pedestrian traffic signal light as shown in the figure, comprising a box body, a plurality of signal lamp holders 6 and a plurality of sunshade units 7, wherein the box body comprises a top plate 1.1, a bottom plate, a panel 1.2, a back plate 1.3 and two side plate units, wherein the side plate units comprise an outer plate 2 and an inner plate 3, wherein a side plate inner space is formed between the outer plate 2 and the inner plate 3, and a box inner space is formed between the inner plates 3 of the two side plate units; the panel 1.2 has a plurality of mounting positions, each mounting position is equipped with a first strip abutment block 4, a strip mounting block 5 and a sunshade unit, each Each installation position has two strip through grooves 1.4 connected to the space inside the box. The sunshade unit 7 includes two side baffles 7.1, a shielding plate 7.2 connecting the two side baffles 7.1, and a second strip abutment block 7.3 fixedly connected to the shielding plate 7.2 and capable of abutting against the first strip abutment block 4. The two side baffles 7.1 are respectively inserted into the two strip through grooves 1.4 of the corresponding installation positions. The shielding plate 7.2 is hinged to the strip installation block 5 by a first elastic reset hinge component. When there is no external force, the shielding plate 7.2 is parallel to the panel 1.2 and blocks the corresponding signal lamp head 6. The inner side plate 3 has a plurality of arcuate through grooves 3.1, and the number of the arcuate through grooves 3.1 on each inner side plate 3 is equal to the number of the mounting positions on the panel 1.2 and the two correspond one to one; the outer side plate 2 has a plurality of positioning sockets 2.1, and the number of the positioning sockets 2.1 on each outer side plate 2 is equal to the number of the mounting positions on the panel 1.2 and the two correspond one to one; the side baffle 7.1 is fixedly connected with a fixing column passing through the arcuate through groove 3.1, and the fixing column is covered with a movable sleeve 7.4, and the movable sleeve 7.4 has a blind hole into which the fixing column is inserted, and the end of the blind hole A spring is connected between the end of the part and the fixed column, the end of the movable sleeve 7.4 can abut the outer panel 2 and can be inserted into the positioning hole 2.1; the sunshade unit 7 can be in a protection state and a sunshade state, in the protection state, the fixed column of the sunshade unit is located at the top of the arc-shaped groove 3.1, and the movable sleeve 7.4 abuts the outer panel 2; in the sunshade state, the fixed column of the sunshade unit is located at the bottom of the arc-shaped groove 3.1, the movable sleeve 7.4 is inserted into the positioning hole 2.1, and the second strip abutment block 7.3 abuts the first strip abutment block 4.

[0041] Each side panel unit is equipped with a driving unit, the driving unit comprising a driving motor 8.1, a screw bearing, a vertical guide rod 8.2, a screw rod 8.3 connected between the driving motor 8.1 and the screw bearing, a lifting block 8.4 and a driving plate 8.5 hinged to the lifting block 8.4 through a second elastic reset hinge component, the lifting block 8.4 has a guide hole matched with the vertical guide rod 8.2 and a threaded hole matched with the screw rod 8.3, the screw rod 8.3 and the vertical guide rod 8.2 are both located in the inner space of the side panel; the second elastic reset hinge component makes the driving plate 8.5 perpendicular to the panel 1.2 when there is no external force; a surrounding convex block is fixed to the movable sleeve 7.4, the surrounding convex block has a circumferential surface 7.5 and a frustum-shaped surface 7.6 connected to the circumferential surface, the driving plate 8. A driving abutment block 8.6 is fixed to the upper surface of 5, and the driving abutment block 8.6 has an abutment inclined surface 8.6.1 that can abut against the frustum-shaped surface 7.6; when the sunshade unit is in the protection state, the driving plate 8.5 passes from top to bottom through the corresponding installation position of the sunshade unit, and the driving plate 8.5 can drive the fixed column to slide downward along the arc-shaped through groove 3.1 until the movable sleeve 7.4 is inserted into the positioning socket 2.1; when the sunshade unit is in the sunshade state, the driving plate 8.5 passes from bottom to top through the corresponding installation position of the sunshade unit, and the driving abutment block 8.6 at the driving plate 8.5 can abut against the surrounding protrusion, so that the movable sleeve 7.4 is disengaged from the positioning socket 2.1, and the fixed column can slide upward along the arc-shaped through groove 3.1 until the shielding plate 7.2 is parallel to the panel 1.2.

[0042] There are five installation positions, which are vertically and evenly spaced. The signal lamp head 6 has a rectangular display screen. A control box is installed in the box, and a control unit, a GPS unit and a wireless communication unit are installed in the control box.

[0043] Working principle: The traffic light of the present application uses a signal light head with a rectangular display screen, so that more complex traffic indication signals can be displayed. In normal use, only the upper signal light head can be used. The sunshade unit of the signal light head already in use is in the sunshade state, so that the traffic signal indication is well performed. The lower signal light heads are not used, so the sunshade unit is in a protective state, so that the shielding plate shields the signal light head, thereby preventing damage to the signal light head.

[0044] Furthermore, the driving unit of the present application can drive the sunshade unit from the protection state to the sunshade state, and can also drive the sunshade unit from the sunshade state to the protection state. When the sunshade unit is driven from the protection state to the sunshade state, since the elastic force of the second elastic reset hinge component is much greater than that of the first elastic reset hinge component, the driving plate will drive the fixed column to move down along the arc-shaped through groove. At this time, the end of the movable sleeve will slide against the outer plate until the movable sleeve is inserted into the positioning socket. At this time, due to the limitation of the movable sleeve and the positioning socket, the fixed column can no longer move. At this time, when the lifting block continues to move downward, the driving plate will rotate upward (such as Figure 7 As shown), until the drive plate passes through the fixing column of the installation position, so that it can be used to drive the next sunshade unit when needed.

[0045] When the sunshade unit is driven from the protection state to the sunshade state, the driving plate passes through the movable sleeve from bottom to top, thereby driving the abutment inclined surface of the abutment block to abut against the frustum surface, so that the movable sleeve contracts toward the inner side plate and disengages from the positioning socket, and under the drive of the driving plate, the fixing column can slide along the arc-shaped through groove until it slides to the top of the arc-shaped through groove. When the fixing column slides to the top of the arc-shaped through groove, it can no longer slide up, so that Fig.14 As shown, the driving plate can be rotated downward until the driving plate passes over the fixing column corresponding to the installation position, so that it can be used to drive the previous sunshade unit as needed.

[0046] The sunshade unit of the present application can switch from the protection state to the sunshade state or vice versa under the drive of the driving unit, thereby remotely controlling the state of the sunshade unit and remotely controlling the display program of the signal lamp head to remotely upgrade the traffic light and increase or decrease the number of signal lamp heads in use.

[0047] 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.
