Description

Red board with lock function

Technical field

The present invention relates to the traffic sign technical field, relate in particular to the red board with lock function of using on a kind of suitable school bus.

Background technology

For the school bus of picking specially the student in the process of moving, often need to stop at seething highway and execute the task, especially school bus need to often be parked in the roadside, allow the student get on or off the bus, if there is not eye-catching alarm signal, other passing hot-shorts are easy to threaten to student's life, thus can the fixed installation red board on the compartment of school bus outside to guarantee student's safety of riding.Existing school bus red board generally comprises control box and warning sign, and control box is fixed on the compartment, and warning sign is connected with control box by pivoted arm.Warning sign launches when the school bus stagnation of movement, in order to point out vehicular traffic and pedestrian, then warning sign is packed up when driving of school bus.Warning sign is affixed on the control box surface after only packing up by pivoted arm when collapsed state, and do not have other anchor fitting to fix warning sign, therefore rocks owing to jolting when driving of school bus, and warning sign easily becomes flexible and comes off, and is unfavorable for the traffic safety of school bus.

Summary of the invention

The warning sign that the present invention is directed to existing school bus red board rocks the problem of easy loose or dislocation owing to jolting when driving of school bus, provide a kind of when driving of school bus since jolt rock not can loose or dislocation the red board with lock function, increase the safety of school bus.

Purpose of the present invention mainly is achieved by following proposal: a kind of red board with lock function, be provided with control box and the warning sign of motor in comprising, one end of described control box arranges pivoted arm, described warning sign links to each other with control box by pivoted arm, the other end of described control box is provided with the warning sign blocking device, and described warning sign blocking device is electrically connected with vehicle power.

Adopt this programme, the other end at control box arranges the warning sign blocking device, like this when in motion warning sign withdrawal of school bus, this moment, the warning sign blocking device was automatically locked warning sign, prevent that school bus from jolting loosening when rocking and cause that school bus board gap is large even drop at long-term road, when the school bus stagnation of movement, the warning sign blocking device is opened, warning sign launches, so this red board has advantages of long service life, safe.

As preferably, described warning sign blocking device comprises electric pushrod and latch hook, and affiliated electric pushrod is built in the control box, and described latch hook is arranged at the control box other end relative with warning sign, and described electric pushrod links to each other by elastomeric element with latch hook.When school bus need to be at curb parking, vehicle power was that electric pushrod send electricity, and the latch hook that electric pushrod will be locked warning sign by elastomeric element this moment is pushed open, and warning sign launches by pivoted arm under the effect of motor.Electric pushrod and vehicle power disconnected after warning sign launched, and latch hook playbacks by elastomeric element; When warning sign was packed up, electric pushrod promoted latch hook again, and warning sign is embedded in the cavity of latch hook, and this moment, latch hook playbacked by elastomeric element, with the warning sign locking, therefore can not occur becoming flexible and coming off jolting to produce when rocking when school bus.

As preferably, described elastomeric element is spring.Spring structure is simple, is easy to produce, and cost is low simultaneously, is conducive to reduce the productive costs of product.

As preferably, be provided with handle on the described latch hook.When vehicle power breaks down, latch hook can be pulled open by handle, warning sign is launched, realize manually pulling open and locking.

As preferably, the other end relative with warning sign of control box also is provided with pressing plate.It is in order to fall within on the pressing plate when warning sign is packed up, warning sign to be played buffering and the effect of protecting that pressing plate is set.

As preferably, be provided with on the described warning sign and surround some LED lamps that pattern is " stopping " word.Pattern on the existing warning sign mostly is and sprays paint or be pasted on the warning sign, easily fall lacquer after period of service is long or come off, and school bus is when parking at night, and the pattern on the warning sign is difficult for seeing.Utilize some LED lamp patterns to surround " stopping " word pattern, the phenomenon that then lacquer can not occur falling or come off still can play good warning function at night simultaneously.

As preferably, described motor is stepping motor.

In a word, the present invention arranges the warning sign blocking device in red board, make school bus in motion warning sign be difficult for loosening and cause and come off, improved the safety of school bus.

The specific embodiment

Below by embodiment, and by reference to the accompanying drawings, technical scheme of the present invention is described in further detail.

A kind of red board as shown in Figure 1, is provided with control box 1 and the warning sign 2 of stepping motor in comprising, an end of described control box 1 arranges pivoted arm 3, and described warning sign 2 links to each other with control box 1 by pivoted arm 3.The other end of described control box 1 is provided with warning sign blocking device 4, as shown in Figure 2, the warning sign blocking device comprises electric pushrod 5 and latch hook 6, affiliated electric pushrod 5 is built in the control box 1, described latch hook 6 is arranged at the other end relative with warning sign of control box 1, and described electric pushrod 5 links to each other by spring 9 with latch hook 6.Also be provided with handle 7 on latch hook, the other end relative with warning sign of control box 1 also is provided with pressing plate 8.

When school bus need to be at curb parking, vehicle power was that electric pushrod 5 send electricity, and this moment, electric pushrod 5 was pushed open by the latch hook 6 that spring will block warning sign 2, and warning sign 2 launches by pivoted arm 3 under the effect of motor.Electric pushrod 5 disconnected with vehicle power after warning sign 2 launched, and latch hook 6 is by spring 9 playback; When warning sign 2 was packed up, electric pushrod 5 promoted latch hook 6 again, and warning sign 2 is embedded in the cavity of latch hook 6, and this moment, latch hook 6 was by spring 9 playback, with warning sign 2 lockings, as shown in Figure 3.When vehicle power breaks down, 7 latch hook 6 can pull open or cuts out by shaking hands, realize manual unlocking and the locking of warning sign.Thereby actv. prevents school bus and comes off jolting loosening when rocking, and prolongs the service life of red board, improves the safety of school bus.

Among the present invention, be provided with on the warning sign 2 and surround some LED lamps 10 that pattern is " stopping " word.Because the pattern on the existing warning sign 2 mostly is and sprays paint or be pasted on the warning sign 2, easily fall lacquer after period of service is long or come off, and school bus to be when parking at night, the pattern on the warning sign 2 is difficult for seeing.Utilize some LED lamp 10 patterns to surround " stopping " word pattern, the phenomenon that then lacquer can not occur falling or come off still can play good warning function at night simultaneously.

Should be understood that this embodiment only to be used for explanation the present invention and be not used in and limit the scope of the invention.Should understand in addition, after the content of having read the present invention's instruction, the equivalent form of value that those skilled in the art change or revise the structures such as elastic component of warning sign blocking device, connection electric pushrod and latch hook falls within the application's appended claims limited range equally.
