Description
Technical Field
[0001] The utility model relates to the technical field of safety auxiliary facilities for buses, in particular to a door opening warning light for buses. Background Art
[0002] A bus is a motor vehicle that carries passengers along a fixed route on urban roads, with or without fixed schedules. It is an important public transportation tool that people can choose for daily travel. When a bus is traveling along its operating route, it usually stops at a station for passengers to get on and off. When the bus arrives at a station and opens the door, passengers often fail to notice that a passenger has already gotten off the bus due to poor visibility at night, rainy days, foggy days, or the carelessness of cyclists, causing the passengers getting off the bus to collide with the cyclists passing by. In addition, some passengers do not have basic safety awareness and fail to look back to see if there are any vehicles passing by behind them when getting off the bus, leading to traffic accidents.
[0003] At present, an electronic display screen is usually installed at the rear of the bus as a safety auxiliary facility. When the bus stops at the station, the electronic display screen will display prompts such as "Stop ahead, keep distance" and "Brake, please pay attention" to remind the vehicles behind to avoid it. However, its warning effect is often not obvious enough, and if there are other vehicles behind the bus, it will form a blind spot, affecting the normal observation of cyclists and passengers getting off the bus, making it difficult for the above warning to produce the expected effect.

When the bus door, i.e., the two door bodies 3 and 4 are closed, the warning light 5 is close to the outer side of the bus door, and the elastic button switch 6 is pressed on the outer side of the other bus door 4 to disconnect the power supply circuit of the warning light 5; when the bus door is opened, the warning light 5 faces the direction of the oncoming vehicle, and the elastic button switch 6 pops up to conduct the power supply circuit of the warning light 5.
[0030] In the present invention, the mounting base 1 includes a mounting panel 101 and a connecting block 102. The mounting panel 101 is provided with an assembly hole 103. The connecting block 102 is fixedly connected to one side of the mounting panel 101 and extends obliquely outward.
[0031] In the utility model, a screw hole is provided on the outer side surface of the door frame of a door body 3 corresponding to the installation panel 101, and a bolt 7 passes through the assembly hole 103 from the outside to the inside and is screwed into the screw hole to fix the installation panel 101 to the outer side of the door frame of the door body, thereby realizing the fixed installation of the mounting base 1 on the outer side surface of a door body 3.
[0032] In the present invention, the housing 2 is fixedly connected to the extended end of the connecting block 102 .
[0033] Since the connection block 102 extends obliquely outward, after the shell 2 is fixedly connected to the extended end of the connection block 102, when the vehicle door is closed, the shell 2 can be retracted to the outside of the vehicle door without interfering with the vehicle door.
[0034] In the present invention, a storage battery 8 is disposed inside the housing 2, and the power output end of the storage battery 8 and the power input end of the warning light 5 are connected to wires 9 and 10 respectively.
[0035] In the utility model, a through hole is provided on one side of the front surface of the shell 2, and a cylinder 11 is fixed in the through hole.
[0036] In the utility model, the elastic button switch 6 includes a first conductive sheet 61, a second conductive sheet 62, a third conductive sheet 63, an insulating telescopic rod 64, an insulating push-pull rod 65, an extrusion sheet 66 and a spring 67. The first conductive sheet 61 and the second conductive sheet 62 are respectively connected to the two wires 9 and 10, and the third conductive sheet 63 is rotatably connected to the end of the second conductive sheet 62. The insulating telescopic rod 64 is slidably sleeved inside the cylinder 11, and both ends of the insulating telescopic rod 64 extend from the inside of the cylinder 11. The two ends of the insulating push-pull rod 65 are respectively rotatably connected to the inner end of the insulating telescopic rod 64 and the inner side of the third conductive sheet 63; the extrusion sheet 66 is fixedly sleeved on the outside of the insulating telescopic rod 64 and abuts against the inner side surface of the outer end of the cylinder 11. The spring 67 is sleeved on the outside of the insulating telescopic rod 64, and the two ends of the spring 67 respectively abut against the inner side surface of the inner end of the cylinder 11 and the extrusion sheet 66.
[0037] Therefore, when the vehicle door is closed, that is, the two door bodies 3 and 4 are closed, the shell 2 rotates inward 90° with one door body 3 and is retracted on the outside of the vehicle door. At this time, the warning light 5 is close to the outer side of the vehicle door, that is, close to but not touching the vehicle door; at the same time, the elastic button switch 6 is squeezed on the outer side of the other vehicle door 4.
[0038] When the vehicle door is opened, that is, the two door bodies 3 and 4 are opened, the housing 2 is unfolded along with one door body 3 rotating outwards 90 degrees and facing the direction of the oncoming vehicle. At the same time, the elastic button switch 6 pops up, so that the warning light 5 lights up.
[0039] In the utility model, a solar cell panel 12 is installed on the back of the housing 2 to charge the storage battery 8 without connecting electricity from the vehicle, thus achieving maintenance-free, energy-saving and environmental protection, and long service life.
[0040] In the utility model, the front side of the housing 2 is provided with an opening.
[0041] In the present invention, the warning light 5 includes a circuit board 51 and a red and blue flashing light group 52 integrated on the outer side of the circuit board 51 , and the circuit board 51 is fixed in the opening.
[0042] Therefore, the rapid alternating flashing of the red and blue LEDs at a frequency of 5 to 15 Hz has a strong warning effect and is not affected by poor visibility environments such as at night, in rainy days, and in foggy days, and can promptly remind cyclists or vehicles behind to pay attention and avoid.
[0043] The utility model is further described below in conjunction with the accompanying drawings:
[0044] When in use, when the door is closed, that is, when the two door bodies 3 and 4 are closed, the shell 2 rotates inward 90° with one door body 3 and is retracted on the outside of the door, which does not affect the overall passability of the bus. At this time, the warning light 5 is close to the outer side of the door, that is, close to but not touching the door; at the same time, the elastic button switch 6 is squeezed on the outer side of the other door 4, so that the warning light 5 is extinguished, which saves electricity and energy and avoids disturbing the passengers in the car.
[0045] Specifically, the insulating telescopic rod 64 is squeezed by the other car door 4 and contracts inward, which, on the one hand, drives the squeezing plate 66 to move inward, compressing the spring 67; on the other hand, it pushes the insulating push-pull rod 65 to move inward, thereby pushing the third conductive plate 63 to deflect outward, breaking away from the contact with the first conductive plate 61, disconnecting the power supply circuit of the battery 8 and the warning light 5, and turning off the red and blue flashing light group 52.
[0046] When the vehicle door is opened, that is, the two door bodies 3 and 4 are opened, the housing 2 is unfolded with one door body 3 rotating outward 90° and facing the direction of the oncoming vehicle. At the same time, the elastic button switch 6 pops up, so that the warning light 5 lights up, reminding the oncoming vehicle from behind to pay attention and avoid it, which can effectively reduce the risk of collision between passengers getting off the vehicle and cyclists and vehicles, reduce the occurrence of traffic accidents, and ensure that passengers can get off the vehicle safely.
[0047] Specifically, the compressed spring 67 stretches and resets, pushing the extrusion sheet 66 to move outward, driving the insulating telescopic rod 64 to move outward, and then pulling the insulating push-pull rod 65 to move outward, pulling the third conductive sheet 63 to deflect inward until it contacts the first conductive sheet 61, and connecting the power supply circuit of the battery 8 and the warning light 5, so that the red and blue flashing light group 52 lights up and flashes rapidly and alternately at a frequency of 5 to 15 Hz, producing a strong warning effect, which is not affected by poor visibility environments such as night, rainy days, foggy days, etc., and can promptly remind cyclists or vehicles behind to pay attention to avoid.
