Problems solved by technology

[0003] In the prior art, either contact or non-contact fatigue detection technology using image sensors is being vigorously developed, but after detecting driver fatigue driving, most of them just send out alarm signals in time, and there are many disadvantages: the stimulation is not strong, It takes a long time to take effect, and the stimulation intensity cannot be adjusted, etc.
If it is driving on the expressway, a slight hesitation in the reaction of the driver of the vehicle will cause inestimable consequences

example 1

[0045] Motion example 1: implementation background, assuming now that a car equipped with the present invention runs smoothly on the highway, in order to prevent or eliminate the driver's sense of fatigue or mental slack caused by long-term driving, the present invention can be received after receiving After the control signal, a certain regular analog vibration is generated quickly. The process of synchronous vibration of the left and right seat plates completed by the present invention is equivalent to simulating the vibration that the wheels on both sides of the vehicle meet the pits at the same time.

[0046] Such as Figure 6 State 1 shown is the normal form of the vibrating seat, and the roller is at the lowest position of the cam, that is, the seat plate is at the lowest position. combine Figure 5 Explanation of the cam snapback mechanism, it should be noted here that the upper and lower protection blocks are in contact with each other at this moment. That is to say...

example 2

[0050] Movement Example 2: In the present invention, the seat boards are designed to be arranged in two piles on the left and right, the purpose of which is that the two seat boards can simulate different vibration modes. Combined with the introduction of a vibration process in exercise example 1, the vibration form of a single seat plate does not change, only need to control whether the left and right motors rotate or change the rotation time sequence of the left and right motors (changing the control signal from the control angle) to achieve different The combination of: 1. The synchronous vibration of the left and right seat plates is equivalent to simulating the vibration when the wheels on both sides of the vehicle encounter pits at the same time; 2. The regular and slow synchronous vibration of the left and right seat plates is equivalent to simulating the vibration when the vehicle encounters a speed bump; 3. The left (right) side seat plate does not move while the right...

Abstract

The invention provides a vehicle cam type vibrating seat. The vehicle cam type vibrating seat comprises a bottom plate, a seat plate and a motor, wherein a bearing supporting frame, at least two inner guide posts and a bolt connecting hole are formed on the upper surface of the bottom plate; the at least two guide posts are laterally symmetrical; the bolt connecting hole is used for fixing the bottom plate to a driving seat; the motor is fixed on the bottom plate; rollers and at least two outer guide slots, which are arranged in a laterally symmetrical manner, are arranged on the lower surface of the seat plate; the outer guide slots are fitted with the inner guide posts on the upper surface of the bottom plate to form a guide mechanism. The vehicle cam type vibrating seat further comprises a cam connecting device, wherein the cam connecting device comprises a bearing, a cam and a big gear wheel, wherein the bearing is arranged on the bearing supporting frame on the upper surface of the bottom plate; the cam is fitted with the rollers on the seat plate to form a cam quick-return mechanism; and the big gear wheel is fitted with a pinion of the motor to form a power transmission mechanism. The vehicle cam type vibrating seat can be used for relieving or removing the feeling of fatigue or laxation of spirit of the driver due to long-time driving.

Description

technical field [0001] The invention relates to a vibration seat for a vehicle, in particular to a cam type vibration seat for vehicle fatigue driving prevention and vigilance. Background technique [0002] With the continuous and rapid development of the social economy and the improvement of the living standards of urban and rural residents, the consumption of automobiles is increasing rapidly. After driving for a long time, the drivers are prone to physiological and psychological disorders, and objectively, the driving skills will decline. The phenomenon. In particular, all vehicles on the expressway maintain a relatively high speed and go their own way in an orderly manner. The energy of the driver is always in a state of high tension, and the physical exertion is also relatively large. Moreover, the speed of the vehicle will be increased unconsciously, and even the brakes will be lost. Slowdown awareness. Driving a vehicle for a long time in this environment will feel ...
