Example 1
As shown in fig. 1, the present invention provides a safety seat including: seat support 1, extension spring 2, bearing 5, support column 4, pull pin 3, the automobile body with the one end fixed connection of support column 4, the other end of support column 4 with the outer periphery fixed connection of bearing 5, the interior circumference of bearing 5 with the middle part fixed connection of seat support 1, still install at the middle part of seat support 1 pull pin 3, the first half of seat support 1 with the one end fixed connection of extension spring 2, the other end of extension spring 2 with automobile body fixed connection.
When the vehicle normally runs, the pull pin 3 limits the movement of the seat 1, and the tension spring 2 is in an extended state.
When the vehicle bumps, extract pull out pin 3, the restriction is relieved to seat support 1, extension spring 2 becomes by the state of stretching the shrink state, the pulling 1 backward rotation of seat support, 1 edge of seat support bearing 5 rotates, the seat is whole to become the horizontality by vertical state, drives the human body and becomes the state of lying flat by sitting, avoids the head to receive the injury.
Simultaneously, in order to guarantee seat pivoted stability, extension spring 2 with the last top end fixed connection of seat support 1 can guarantee like this the pivoted range of seat is the biggest, makes the human state that tends to lie flat as far as.
Finally, in order to avoid receiving when the seat rotates the hindrance of automobile body, extension spring 2 with the junction of seat support 1 arrives the length more than or equal to of bearing 5 the bearing 5 arrives the length of 1 bottom of seat support can guarantee like this during the seat vertical condition can just with the automobile body overlap joint the seat becomes the in-process of horizontality, seat support 1 can not because with the automobile body takes place the friction and then leads to the rotation to receive the hindrance, causes the equipment obstacle.
Example 2
As shown in fig. 2, the safety seat provided by the invention comprises a seat 1, a tension spring 2, a support column 4, a bearing 5, an electromagnetic valve 6, an armature 7 and a sensor 8, wherein the connection relationship between the seat 1 and the tension spring 2, the support column 4 and the bearing 5 is the same as that in embodiment 1, the lower half part of the seat 1 is overlapped with the armature 7, the armature 7 is overlapped with the electromagnetic valve 6, the electromagnetic valve 6 is connected with the sensor 8, and the sensor 8 is arranged at the front end of the vehicle body.
When the vehicle normal operating, sensor 8 has not received the signal, 6 outage solenoid valves, armature 7 with the latter half overlap joint of seat support 1 restricts seat support 1's rotation, when the vehicle bumps, sensor 8 receives the signal, 6 circular telegrams of solenoid valve will armature 7 adsorbs downwards, the restriction is relieved to seat support 1, 2 stimulations of extension spring seat support 1 is followed support column 4 rotates, the seat is whole to become the horizontality by vertical state, drives the human body and becomes the state of lying by the position of sitting, reaches the effect of protection human body.
6 inside electro-magnets and the spring of being provided with of solenoid valve, the spring with armature 7 fixed connection, when the vehicle normally traveles, the electro-magnet does not switch on, the spring is in the state of stretching, armature 7 with 1 overlap joint of seat support, when the vehicle collision, 6 circular telegrams of solenoid valve, the electro-magnet will armature 7 adsorbs downwards, the spring is in compression state, armature 7 with seat support 1 does not overlap joint, seat support 1 rotates.
In order to guarantee the angle that seat support 1 was faced back, preferably the seat sets up all around and is provided with the horizontal pole, back horizontal pole with armature 7 overlap joint is used for the restriction the rotation of seat support 1, preceding horizontal pole with seat support 1 overlap joint is used for the restriction the angle that seat support 1 was faced back, and so, the seat of facing back just can play the effect of protecting the passenger.
The sensor 8 is set as a photoelectric sensor, a sensor 8 tester is set for protecting the normal operation of the photoelectric sensor, and the sensor 8 tester can convert 220V alternating current into 12V direct current through a rectifier bridge and a voltage stabilizer to be used as a power supply of the photoelectric sensor and a signal amplification circuit.
When an obstacle appears in front of the photoelectric sensor, the photoelectric sensor transmits a signal to the amplifying circuit, the relay receives the signal and is closed, the electromagnetic valve 6 is switched on to start working, the electromagnet inside the electromagnetic valve 6 is electrified to adsorb the armature 7 downwards, and the seat 1 rotates.
The sensor 8 is set as an automatic door sensor, the detection distance of the sensor can be adjusted according to the actual situation of use, and the rest is consistent with the photoelectric sensor.
In order to detect different distances of different vehicle speeds, the invention is provided with a control module which is connected with a signal processing circuit of the vehicle, when the vehicle runs at different vehicle speeds, the signal processing circuit converts a pulse signal input by a vehicle speed sensor into a current signal proportional to the vehicle speed, then the current signal is synchronously transmitted to the control module, the control module receives the current signal, and then the instant vehicle speed of the vehicle is obtained, and then different signals are sent out:
when the vehicle speed is 0-30km/h, the control module energizes a first sensor, and the first sensor senses the vehicle in a range of 2m in front of the vehicle body;
when the vehicle speed is 30-60km/h, the control module supplies power to a second sensor, and the second sensor senses the vehicle within 15m in front of the vehicle body;
when the vehicle speed is 60-120km/h, the control module supplies power to a third sensor base, and the third sensor senses the vehicle within 30m in front of the vehicle body.
The first sensor, the second sensor and the third sensor are connected in parallel, are communicated with the electromagnetic valve and control the closing of the electromagnetic valve.
Finally, it is to be understood that the above embodiments are merely exemplary embodiments taken to illustrate the principles of the present invention, which is not intended to be limiting. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle and spirit of the invention, and such modifications and improvements are also considered to be within the scope of the invention.
