Disclosure of Invention

The invention aims to provide an automatically-adjustable baffle plate mounting structure and an adjusting method, which do not need people to operate a switch baffle plate outside a vehicle, reduce potential safety hazards and improve adjusting convenience.

In order to solve the technical problems, the automatically-adjustable bullet baffle mounting structure comprises a bullet baffle, a telescopic device, an operating switch and a controller, wherein a plurality of rotary supports are arranged between the bullet baffle and the top of a front windshield of a vehicle, the rotary supports are rotatably connected with the top of the front windshield, the rotary supports are fixedly connected with the bullet baffle, the tail end of the telescopic device is hinged to a top cover of the vehicle body, a telescopic rod of the telescopic device is hinged to the rotary supports and can drive the rotary supports to rotate, the operating switch is arranged in the vehicle, and the controller is electrically connected with the telescopic device and the operating switch.

In above-mentioned fender apron mounting structure, personnel in the car pass through operating switch and controller cooperation, and control telescoping device's telescopic link is flexible, and then the drive runing rest drives the fender apron rotation, realizes the distal end control that the fender apron opened and shut. When the vehicle normally runs, the baffle plate is rotated upwards to be opened, so that a good driving visual field is kept, and the normal running is not influenced; when meeting emergency, cover the wind window before the fender apron is rotatory downwards, protect to can avoid under emergency, the people carries out manual operation's inconvenience to fender apron outside the car, improves and adjusts the convenience, can realize shellproof protection fast simultaneously, reduces the potential safety hazard.

As an improvement of the mounting structure of the baffle plate, a pressure sensor is arranged on the mounting frame of the front windshield, and the pressure sensor is electrically connected with the controller. The impact pressure that glass on the wind window received before measuring is perceived through pressure sensor in real time to receive the pressure signal who handles pressure sensor through the controller, when real-time impact pressure value exceeded the threshold value of settlement, the action of controller control telescoping device made fender diving board rotate down to the closed position, thereby realize when meetting emergency, the fender was automatic protects preceding wind window and personnel in the car, made the protection more timely, quick.

In the above technical solution using the pressure sensor, the controller may adjust a telescopic speed of the telescopic rod of the telescopic device. The speed of the telescopic device is adjustable, when the real-time impact pressure value of the current air window exceeds a set threshold value, the controller controls the telescopic device to act, the telescopic speed of the telescopic rod is increased, the time required by closing the baffle plate is shortened, and the protection speed is further increased. When the baffle plate is adjusted manually in the usual way through the operating switch, the controller properly reduces the speed of the telescopic device, and the baffle plate is easier to adjust to a desired angle.

As another improvement of the mounting structure of the bullet-proof plate, the mounting structure further comprises a limiting device, the limiting device comprises an opening limiting device and a closing limiting device, the opening limiting device is used for preventing the bullet-proof plate from continuously rotating when the bullet-proof plate rotates upwards to a certain angle, and the closing limiting device is used for preventing the bullet-proof plate from continuously rotating when the bullet-proof plate rotates downwards to cover the front windshield. The limiting device is started to limit the maximum opening degree of the opening of the elastic baffle plate, so that the upward opening degree is prevented from being too large, and the influence of larger wind resistance on the elastic baffle plate is avoided in the running process of a vehicle; the baffle plate is just limited at the angle of the front windshield of the perfect cover cap by closing the limiting device, so that higher protection quality is ensured.

In the above-mentioned technical scheme that adopts stop device, preferably the rotation of fender diving board is back and the contained angle of preceding windshield plane is 0 ~ 65. In normal conditions, the elastic baffle rotates to 65 degrees, and the main body is basically kept horizontal, so that good driving vision and good air flow passing performance can be ensured; in addition, the bullet-proof board not only can shield the sun light and protect the eyes of the driver without dazzling, but also can shield the light reflected by the glass of the front windshield by the sun, thereby avoiding being easily detected. The baffle plate can also be rotated to 0 degree and perfectly covered with the front windshield, so that the maximum protection is realized.

As a further improvement of the mounting structure of the bullet-stopping plate of the present invention, the telescopic device employs an electric stay bar assembly. The electric support rod assembly is adopted, so that the structure is simple, and the occupied space is small; the control is easy, the accuracy is high, and the bulletproof plate can be adjusted to any angle in the limit stroke range and maintained; when the electric stay bar is closed, the position is kept, no drift occurs, and the static load handling characteristic is better.

In order to solve the above technical problem, the method for adjusting the baffle plate based on the above baffle plate mounting structure of the present invention includes: measuring real-time impact pressure on a front air window; setting a threshold value of the front windshield impact pressure; comparing the real-time impact pressure with a set threshold value, if the real-time impact pressure is larger than the set threshold value, controlling the telescopic device to act, and rotating the retainer plate downwards; and monitoring the position signal of the bullet baffle at the position of the closing limiting device in real time, and stopping the action of the telescopic device if the position signal of the bullet baffle is detected.

As an improvement of the adjusting method of the baffle plate, before the telescopic device is opened and the baffle plate is rotated downwards, the method further comprises the steps of canceling all real-time control commands of the baffle plate and stopping the rotation action of the baffle plate. And stopping all actions of the bullet, and only executing the control command of automatic adjustment to avoid command conflict.

As another improvement of the adjusting method for the baffle plate, before the telescopic device is opened and the baffle plate is rotated downwards, the method further comprises the step of increasing the telescopic speed of the telescopic rod of the telescopic device. Adjust the fender apron rotation with faster speed, shorten and close the fender apron time, further accelerate the speed of protection.

According to the adjusting method of the baffle plate, whether the vehicle is in an emergency dangerous condition or not is judged in real time by comparing the impact pressure on the front windshield with the set threshold value, namely, the vehicle is in the emergency dangerous condition when the real-time impact pressure is larger than the set threshold value, then the telescopic device is immediately opened, the baffle plate is adjusted to rotate downwards, and the telescopic device is closed after the baffle plate is sensed to reach the closed position, so that the baffle plate is automatically closed, and the protection of the front windshield under the emergency condition is rapidly completed.

Preferably, the telescopic device 2 adopts an electric stay bar assembly. The electric stay bar is adopted as the actuating mechanism, so that the structure is simple, the air source device and auxiliary equipment required by the pneumatic actuating mechanism can be reduced, and the weight of the actuating mechanism can also be reduced; and when the bullet baffle 1 is opened, power needs to be supplied, and the power can not be supplied when the required opening degree is reached, so that energy is saved. In addition, the electric stay bar can also accurately rotate the baffle plate 1 to any angle, and keep the baffle plate stationary, and can be flexibly adjusted according to actual requirements.

The working principle of the installation structure of the elastic baffle plate 1 is as follows: the rear end of the electric support rod component is connected to the top cover 52 of the vehicle body through a hinge seat, and the telescopic rod at the front end is hinged to the middle part of the rotating support 4, so that the electric support rod component can push the rotating support 4 to drive the bullet baffle 1 to rotate; further, in the process of rotating the damper 1, an opening stopper 61 is provided on the roof 52, and a closing stopper 62 is provided on the frame of the windshield 51, so that the damper 1 is rotated within a predetermined range. The operating switch 3 comprises an open key, a close key, an upper adjusting key and a lower adjusting key, and then the following three manual control states of the baffle plate 1 can be realized through the operating switch 3:

firstly, when the bullet-proof board 1 is in an open state: as shown in fig. 1 and fig. 2, when the open key is pressed, the electric stay bar is retracted until the open limit bracket 611 and the open limit block 612 are matched with each other for limiting, and the included angle between the bullet-blocking plate 1 and the plane of the front windshield 51 is 65 degrees, which is basically kept parallel to the roof 52 of the vehicle body.

Continuously pressing a lower adjusting key of an operation switch 3 in the vehicle, enabling an electric stay bar to extend, enabling the electric stay bar to rotate 1 degree upwards around a hinge shaft at the rear end of the electric stay bar every time the electric stay bar extends for 60mm, simultaneously enabling a rotating support 4 to drive a bullet-blocking plate 1 to turn downwards around a rotating shaft, and loosening the operation switch 3 in the turning process to stop turning, so that the bullet-blocking plate 1 can be stopped at any number of degrees within the range of 0-65 degrees; similarly, the retainer plate 1 can be adjusted upward to any angle by continuously pressing the upper adjusting key. In addition, the upper adjustment key or the lower adjustment key is pressed once, and the retainer plate 1 rotates by only one corresponding unit angle.

In order to realize the automatic adjustment of the damper plate 1, as shown in fig. 1 and 4, a pressure sensor 9 is provided on the mounting frame of the front windshield 51, and the pressure sensor 9 is electrically connected to the controller 8. When the bullet hits on the glass of preceding windshield 51, the glass is whole to receive impact pressure, the real-time perception of pressure value that receives on windshield 51 through pressure sensor 9 to give controller 8 with pressure value signal transmission, when measured pressure value reached the threshold value of settlement, controller 8 automatic control baffle 1 is rotatory downwards, makes it cover at once and protects on windshield 51, realizes automatic protection and adjusts.

Preferably, the controller 8 can adjust the telescopic rod telescopic speed of the telescopic device 2. The telescopic device 2 can be an electric stay bar component adopting a three-phase motor and is externally connected with an alternating current motor speed regulator to realize speed change; the variable-frequency motor can also be applied as a drive to realize speed change. The speed of the telescopic device 2 is designed to be adjustable, when the telescopic device is manually adjusted at ordinary times, the telescopic rod is telescopic, the rotating speed of the elastic baffle plate 1 is low, and when the telescopic device is automatically adjusted, the speed is high. When the real-time impact pressure value of the front windshield 51 exceeds a set threshold value, it is determined that an emergency situation occurs, the controller 8 controls the telescopic device 2 to contract the telescopic rod at a higher speed, the time required by closing the baffle 1 is shortened, and the protection speed is further increased; when the damper is normally adjusted manually by operating the switch 3, the controller 8 appropriately reduces the speed of the retractor device 2, making it easier to adjust the damper 1 to a desired angle.

When the elastic baffle plate 1 is automatically adjusted, a travel switch is required to be added, so that the elastic baffle plate can automatically stop when reaching a closed state, and the electric stay bar is prevented from being damaged. As shown in fig. 2 and 5, the opening limiting device 61 and the closing limiting device 62 are both provided with a position sensor 7, and the position sensor 7 is electrically connected with the controller 8. Position sensor 7 is integrated respectively to open stop device 61 and close stop device 62 on, utilizes the position information of fender diving board 1 of controller 8 reception position sensor 7 perception, and then controls telescoping device 2, realizes when fender diving board 1 reachs the start-stop position, and the function of automatic shutdown telescoping device 2 assists the complete automatic control under the emergency.

When in use, the electrical connection mode of the controller 8 is as shown in fig. 7, and the installation structure of the baffle plate 1 automatically controls the flow: the pressure sensor 9 monitors the impact pressure on the front windshield 51 in real time; the controller 8 receives the pressure signal, analyzes and processes the pressure signal, and controls the telescopic device 2 to act to enable the baffle plate 1 to rotate downwards when the pressure value exceeds a threshold value; when the baffle plate 1 rotates to be contacted with the closing limiting device 62, the position sensor 7 on the closing limiting device 62 detects the position of the baffle plate 1 and transmits a position signal to the controller 8, then the telescopic device 2 is closed, and the closing operation of the baffle plate 1 is completed.

The invention relates to an automatically adjustable baffle plate adjusting method based on the baffle plate mounting structure, which comprises the following steps:

s01: the real-time impact pressure to which front windshield 51 is subjected is measured. The impact pressure on the windshield of the front windshield 51 is monitored in real time by the pressure sensor 9 mounted on the frame of the front windshield 51, and a pressure value signal is transmitted to the controller 8.

S02: a threshold value for the front windshield 51 impact pressure is set. The threshold value is obtained according to actual measurement, so that the bulletproof glass of the front windshield 51 responds to immediately act when being impacted by a bullet for the first time, the bullet baffle 1 is closed, and the front windshield 51 can be kept intact below the impact pressure corresponding to the threshold value.

S03: and comparing the real-time impact pressure with a set threshold value, and if the real-time impact pressure is greater than the set threshold value, controlling the telescopic device 2 to act and rotating the baffle plate 1 downwards. And after receiving the real-time impact pressure, the controller 8 compares the real-time impact pressure with a set threshold value for judgment, and determines whether the baffle plate 1 needs to be closed or not according to a comparison result. When the real-time impact pressure is larger than a set threshold value, judging that an emergency dangerous condition is entered, immediately stopping all other control instructions of the controller 8 to the telescopic device 2, only executing an instruction for enabling the telescopic device 2 to extend out of the telescopic rod, and driving the baffle plate 1 to rotate downwards; and when the real-time impact pressure is smaller than the set threshold value, no action is performed, and the comparison and judgment process is ended.

In step S03, before controlling the operation of the retractor device 2 and rotating the kick plate 1 downward, the method further includes: the expansion speed of the expansion device 2 is increased. The time for closing the deflector 1 is further shortened.

S04: and monitoring position signals of the elastic baffle plate 1 at the position of the closing limiting device in real time, and stopping the movement of the telescopic device 2 if the position signals of the elastic baffle plate 1 are detected. In the previous step, the ballistic plate 1 is automatically rotated downward, and thus a form switch is required to stop it. The position sensor 7 (which may be a proximity sensor) integrated at the closing limit device 62 monitors in real time until the bullet-proof plate 1 is monitored, that is, the bullet-proof plate 1 rotates to the closed position, and the controller 8 receives the signal of the position sensor 7 in response, closes the telescopic device 2, and completes the operation of automatically closing the bullet-proof plate 1.

The adjusting method is an automatic adjusting method of the bullet baffle in an emergency, manual participation is completely not needed, and automatic response is achieved at any time. When the automatic adjustment method is started, the controller 8 will suspend receiving the control signal of the operation switch 3 and stop the control command being executed, i.e. stop the function of manual adjustment. In addition, no matter whether the bullet-proof board 1 is in any state of opening, closing and any angle, after the automatic adjustment response, the telescopic device 2 can be driven to extend, and the bullet-proof board 1 is ensured to be closed in place.
