Description

Technical Field

[0001] This utility model belongs to the field of vehicle parts technology, specifically relating to a vehicle emergency smoke warning device. Background Technology

[0002] When a vehicle is traveling, it may become stuck on the road due to an accident. In order to avoid collisions between the following vehicles and the stuck vehicles, it is necessary to give timely warnings to the following vehicles. The traditional way is to place a warning sign 50-100 meters away from the accident vehicle. However, the person placing the warning sign needs to walk on the lane, which is a dangerous process and can easily cause safety accidents.

[0003] Chinese patent CN218949134U discloses a vehicle-mounted smoke generator and a vehicle. The solution includes a smoke generating structure, a triggering device, and a housing box. The smoke generating structure and the triggering device are located inside the housing box. The smoke generating structure includes a smoke generating pull ring, a smoke pulling rope, and a smoke generating body. The above solution uses the triggering smoke generating body to generate a large amount of smoke to achieve the effect of attracting attention.

[0004] The above-mentioned scheme, after adjustments, can be used to warn following vehicles in the lane after a vehicle accident. However, the smoke emission time of a single smoke generator is limited, resulting in a short duration of warning for following vehicles. Utility Model Content

[0005] The present invention aims to provide a vehicle emergency smoke warning device to solve the problem that the warning duration for following vehicles is too short in the above-mentioned solutions.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A vehicle emergency smoke warning device includes a storage box, smoke generating components, and a triggering mechanism. The storage box has an inner cavity with a partition fixedly installed vertically within it. N threaded holes, where N is a natural number not less than 2, are spaced horizontally along the right side wall of the storage box and extend into the inner cavity. N smoke generating components are provided, each including a smoke generating body, a transmission component, and a pulling component. One end of the transmission component is fixedly connected to the pulling component, and the other end extends into the interior of one end of the smoke generating body. The outer side wall of one end of the smoke generating body is threaded into a corresponding threaded hole. The triggering mechanism includes a collision sensor and N triggering components. The collision sensor is fixedly installed on the left side wall of the partition. Each triggering component includes an electric drive component and a time control switch fixedly installed on the right side wall of the partition. The electric drive component is positioned opposite to the threaded holes and is electrically connected to the time control switch. Each time control switch is electrically connected to the collision sensor.

[0008] The principle and effects of this technical solution:

[0009] The storage box is fixedly connected to the car body. Then, one end of each of the N smoke generators is threaded into the corresponding screw holes. When the car is stuck in the lane due to an accident, the collision sensor activates each time control switch after sensing the collision. One of the time control switches immediately triggers the electric drive to work. The electric drive pulls the puller to move, which in turn pulls the transmission to trigger the smoke generator to produce a large amount of smoke, thus providing a warning to the vehicles behind in the lane. The remaining time control switches increase the preset opening time one by one. Each increase in opening time is equal to the continuous smoke emission time of the smoke generator.

[0010] With the above settings, when a car collision occurs, the triggering mechanism can trigger the N smoke generators inserted into the side wall of the storage box one by one, extending the smoke generation time of the device and continuously providing warnings to following vehicles in the lane, thus solving the problem of the short duration of warnings to following vehicles in the above solutions.

[0011] In this invention, the electric drive component is an electromagnet, which can magnetically pull the pulling component. Through this configuration, by using the magnetic force generated by the electromagnet to pull the pulling component, the purpose of triggering the smoke generator to produce smoke can be achieved.

[0012] In this invention, a protective shell is fixedly installed on the right side wall of the storage box around N screw holes. The protective shell has channels arranged in the left-right direction, and a cover plate is provided at the right end of the protective shell. The cover plate has through holes aligned with the screw holes. This design prevents the smoke generator from colliding with external objects during vehicle operation and avoids damage. Simultaneously, it allows the smoke generated by the smoke generator to be discharged through the through holes, extending the service life of the device.

[0013] In this invention, the protective shell and the cover plate are fixedly connected by bolts.

[0014] In this invention, there is a gap between the outer wall of the smoke generator and the inner wall of the protective shell, and gaskets are fixedly provided on the upper and lower sides of the inner wall of the protective shell respectively.

[0015] The above-mentioned design can prevent the smoke generator from breaking due to the up-and-down movement of the vehicle body during driving, thus further extending the service life of the device.

[0016] In this invention, mounting plates are fixedly installed at the top left end of the storage box and the top right end of the protective shell, respectively. The front and rear ends of the two mounting plates each have through mounting holes. Bolts are passed through the mounting holes, and the threaded portion of the bolts is threaded into the pre-drilled holes in the vehicle body until the bolt caps and the vehicle body press against the mounting plates. This arrangement achieves the purpose of fixing the device to the vehicle body.

[0017] In this invention, a notch is provided at the top of the cover plate below the mounting hole. After the device is fixed to the car body, the cover plate is installed at the right end of the protective shell. At this time, the bolt cap of the bolt passing through the mounting plate at the top right end of the protective shell is located in the notch. Through the above-mentioned arrangement, it is convenient for workers to fix the cover plate to the right end of the protective shell, thereby improving installation efficiency.

[0031] In this embodiment, a protective shell 40 is fixedly provided on the right side wall of the storage box 10 outside the N screw holes 13. The protective shell 40 has a channel arranged in the left and right direction. A cover plate 41 is provided on the right end of the protective shell 40.

[0037] The storage box 10 is fixedly connected to the car body. Then, one end of each of the N smoke generators 21 is threaded into the corresponding screw holes 13. When the car is stuck in the lane due to an accident, the collision sensor 31 activates each time control switch 322 after sensing the collision. One of the time control switches 322 immediately triggers the electric drive component 321 to work. The electric drive component 321 pulls the pull component 23 to move, which in turn pulls the transmission component 22 to trigger the smoke generator 21 to generate a large amount of smoke, thus providing a warning to the following vehicles in the lane. The remaining time control switches 322 increase the preset opening time one by one. Each increase in opening time is the continuous smoke emission time of the smoke generator 21.
