[0031] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model, and apparently, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.
[0032] Please refer to Figs. 1 to 4 The utility model provides a technical scheme: a drunk driving automatic anti-escape and collision device, comprising:
[0033] The road surface sensing module comprises a rubber pad arranged in the drunk driving inspection area, and the rubber pad is internally fixedly connected with a pressure sensor, a proximity sensor and a mobile signal transmitter.

[0040] The specific structure of the alcohol tester in the embodiment is the same as that in the prior art. When detecting alcohol, the driver blows into the blowing pipe, and the blowing pipe transmits the air to the alcohol gas sensor for detection. The resistance value of the alcohol gas sensor decreases with the increase of the alcohol gas concentration. If the driver exhales more alcohol gas, the voltmeter of the tester shows a larger number, so that the alcohol content in the gas can be measured.
[0041] In addition, a power supply is arranged on one side of the rubber pad, and the pressure sensor and the mobile signal transmitter are electrically connected with the power supply. The power supply includes wires fixedly connected in the power supply. The power supply is electrically connected with the mobile signal transmitter and the plurality of pressure sensors through the wires. The power supply can continuously supply power to the plurality of pressure sensors and the mobile signal transmitter, so that the rubber pad is convenient to carry and can be placed on the ground at any time for use.

[0043] In addition, in the technical scheme, the devices such as the mobile signal transmitter, the wireless signal transmitter and the signal receiver which need to transmit signals are all added with the MQTT instant communication protocol, so that the signal transmission is smooth and unblocked.
[0044] Preferably, the limiting part 4 comprises:
[0045] The connecting plate 41 is fixedly connected with the output shaft of the driving motor 3 at the center thereof;
[0046] The limiting sleeve rod 42 is fixedly arranged at both ends of the connecting plate 41;
[0047] The limiting push rod 43 is slidably arranged in the inner cavity of the limiting sleeve rod 42;
[0048] The spring 44 is arranged between the limiting sleeve rod 42 and the limiting push rod 43, one end of the spring 44 is fixedly connected to the bottom of the inner cavity of the limiting sleeve rod 42, and the other end of the spring 44 is fixedly connected to the top end of the limiting push rod 43, in the normal state, the connecting plate 41 is parallel to the axis of the throttle valve plate 2, the limiting push rod 43 abuts against the left and right ends of the axis of the throttle valve plate 2, and does not affect the normal rotation of the throttle valve plate 2, and the vehicle power can normally drive.
[0049] Preferably, the bottom end of the driving motor 3 is further provided with a buckle fixing part 5; the buckle fixing part 5 comprises a fixed plate 51 and clamps 52 symmetrically arranged at both ends of the fixed plate 51, and the buckle fixing part 5 is rigidly connected with the shell of the original electronic throttle valve body 1 of the vehicle through the clamps 52.
[0050] Vehicle detection and signal triggering stage: a rubber pad is arranged at a position 50 meters away from the alcohol driving checking position (or according to the actual situation), when the vehicle enters the alcohol driving checking area, the rubber pad of the road surface sensing module senses the wheel pressure through the built-in pressure sensor to determine that the vehicle has arrived; the proximity sensor synchronously detects the parking state of the vehicle. After confirming that the vehicle is parked stably, the mobile signal transmitter sends an encrypted radio frequency signal to the vehicle-mounted signal receiving module, then the controller sends an instruction to the throttle actuator to drive the motor 3 to start, and the output shaft drives the connecting plate 41 to rotate 90°, so that the connecting plate 41 is perpendicular to the axis of the throttle valve plate 2, at this time, the limit push rod 43 is in contact with the upper and lower ends of the throttle valve plate 2, and the limit push rod 43 extends axially along the limit sleeve rod 42 under the action of the spring 44 to push the throttle valve plate 2 to force the throttle opening to be limited. At this time, the maximum opening of the throttle is mechanically locked to the idle state, the engine intake is suddenly reduced, the vehicle loses the acceleration ability, and the limiting part 4 is provided with the spring 44 buffering design to provide flexible constraint when limiting the throttle opening, so that mechanical impact and component damage are avoided.
[0051] Alcohol concentration detection stage:
[0052] The vehicle-mounted signal receiving module transmits the trigger instruction to the control module, and the controller activates the alcohol detection module. The driver blows the alcohol gas sensor through the blowing pipe, the internal semiconductor gas sensitive element of the sensor reacts with alcohol molecules to cause the resistance value to change. The resistance change is converted into a voltage signal through the voltage dividing circuit composed of a fixed value resistor and a voltmeter, and the alcohol concentration value is displayed in real time.
[0053] Control decision and execution stage: in the normal state, if the detection value is lower than the set threshold value, the driving motor 3 drives the limit push rod 43 to reset, the throttle actuator is released, and the vehicle can pass normally; in the alcohol driving state, if the detection value exceeds the standard, no signal is sent, the limit push rod 43 on the vehicle is not reset, and the second detection is carried out, when alcohol driving and drunk driving are reached, the police handle and control the vehicle according to the situation.
[0054] The utility model discloses a three closed loop control of road surface-vehicle linkage detection, alcohol concentration real-time determination and throttle mechanical limiting, can complete the whole process from vehicle identification to power limitation quickly, effectively eliminates the delay of human intervention. The electronic throttle valve body keeps communication with the ECU through the CAN bus, ensures that the engine maintains the minimum speed during the limiting period, realizes vehicle braking and avoids the secondary accident risk caused by engine stall. The part not involved in the utility model is the same as the prior art or can be realized by using the prior art.
[0055] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application have been described in detail, for the skilled in the art, it still can be modified, or for the equivalent replacement of part of the technical features of the technical solutions recorded in the foregoing embodiments.
