detailed description

As shown in Figures 1 and 2, a multi-view early warning safety helmet includes a helmet body, which is provided with a distance measurement and early warning device for detecting the distance value when driving and making a decision when the distance value exceeds the set value. Feedback, when the distance value exceeds the set value, the inside of the helmet will alarm to remind the user that the distance between the detected object and the detected object is too close, and safety needs to be paid attention to.

Further, the ranging early warning device includes

Ultrasonic emitting part 2, the ultrasonic emitting part 2 is arranged on the outer wall of the helmet body 1 for emitting ultrasonic signals;

The ultrasonic receiving part 3, the ultrasonic receiving part 3 is arranged on the outer wall of the helmet body 1 and is close to the ultrasonic emitting part 2 for receiving the ultrasonic signal sent by the ultrasonic emitting part 2 and reflected back;

A processing module, the processing module is located inside the helmet body 1 and is electrically connected to the ultrasonic transmitting part 2 and the ultrasonic receiving part 3 respectively for detecting the time of the ultrasonic signal from transmitting to returning to receiving and converting it into a distance value; and

a buzzer, the buzzer is located on the left and right sides of the helmet body 1 and is electrically connected to the processing module,

There are three ranging warning devices, which are respectively arranged on the left side, the right side and the rear of the helmet body 1 .

The working principle of the ranging warning device is: use the IO port TRIG to trigger the ranging, and give a high-level signal of at least 10us; the module automatically sends 8 square waves of 40khz, and automatically detects whether there is a signal return; if there is a signal return, it passes through the IO port ECHO outputs a high level, and the duration of the high level is the time from the emission to the return of the ultrasonic wave. The test distance = (high level time * sound speed (340M/S))/2.

The ultrasonic transmitting part 2 emits ultrasonic waves, and the ultrasonic waves are received by the ultrasonic receiving part 3 after being reflected by the object. The processing module uses the time difference distance measurement method to measure the time difference t until the ultrasonic waves are sent out and reflected back by an obstacle through a timer. According to The known propagation velocity of ultrasonic waves in the air is 340m/s. According to the principle of time difference ranging, it can be known that the distance value D=340t/2 from the emission point to the obstacle.

When there is a car or obstacle close to the user, if the distance value D judged by the processing module is less than the set value, the processing module will control the buzzer to issue an early warning. The right buzzer sounds, and when a car comes from behind, the buzzers on both sides sound at the same time, reminding the user of the direction of the car and preventing accidents.

As shown in Figure 3, the helmet body 1 is provided with an optical rear view channel 4, and the optical rear view channel 4 extends from the rear of the helmet body 1 to the upper front of the helmet body 1 for the user to observe the rear view from the front of the helmet body 1 , this design allows the user to use the utility model to observe the driving conditions behind the field of vision, and can also observe more flexibly by turning the head and then turning the optical rear-view channel 4 .

Still further, the optical lens assembly includes

Concave lens 5, this concave lens 5 is arranged in the port of casing 41 that is positioned at the end of helmet body 1 rear;

Convex lens 6, this convex lens 6 is arranged in the port of housing 41 extending to the end of the front upper part of helmet body 1;

A reflection mechanism 7, which is arranged on the inner wall of the housing 41 and is located between the concave lens 5 and the convex lens 6 for reflecting the light passing through the concave lens 5 onto the convex lens 6; and

Look objective lens 8, this look objective lens 8 is positioned at the below of convex lens 6, and one end of look objective lens 8 is hinged with casing 41, and look objective lens 8 one end is provided with circular hole, is actively connected with the latch on the casing 41, when driving, the rear The field of view passes through the refraction and reflection of the lens in the optical rearview channel 4, and shoots into the front and upper viewing lens 8 inside the helmet body 1. The user only needs to glance at the objective lens 8 to know the rear situation, which solves the problem of the rear view of the traditional rearview mirror. For the problem of the blind spot, the angle of the objective lens 8 is adjustable, which can adapt to the user's visual field position.

The working principle of the optical assembly is: when driving, the rear image enters the optical rearview channel 4 through the concave lens 5, and is reflected to the convex lens 6 by the reflection mechanism 7, and the convex lens 6 converges the image onto the objective lens 8.

Preferably, the reflection mechanism 7 is configured as a reflection mirror or a combination of two or more reflection mirrors, and the reflection mirror is glued to the inner wall of the casing 41 .

For further optimization, LED warning lights 9 are provided on both sides of the front end of the helmet body 1. As shown in FIG. For example, if there is a ditch or a brick, the grid will be obviously deformed to remind the user that the road ahead is dangerous. The LED warning lamp 9 is not limited to high-power LED lamps, but can also be a combination of multiple low-power LED lamps, or obtain high-power LED lamps by means of board integration.

In addition, the helmet body 1 is provided with a bluetooth earphone, which can be connected to an external mobile phone, and the user can answer calls and listen to music while driving.

The above is only the preferred implementation of the utility model, the utility model is not limited to the above implementation, as long as the technical solutions to achieve the purpose of the utility model by basically the same means are within the scope of protection of the utility model.
