[0019] The following is combined with Figure 1-4 This application is described in further detail.

[0020] The present application embodiment discloses a vehicle alcohol lock device. Figure 1-4A vehicle alcohol lock device includes a device body 1, a fuel cell sensor 2 is fixedly installed on the inner wall of the device body 1, the blowing end of the fuel cell sensor 2 penetrates and extends out of the outside of the device body 1, an A / D converter 3 is installed on the inner wall of the device body 1, the A / D converter 3 is electrically connected to the fuel cell sensor 2, a single-chip computer 4 is also installed on the inner wall of the device body 1, the single-chip computer 4 is electrically connected to the A / D converter 3, an interface 401 is installed on the outer wall of the single-chip computer 4 near the top of the device body 1, the interface 401 penetrates the device body 1, a data line 5 is plugged into the inner wall of the interface 401, and the end of the data line 5 away from the interface 401 is connected to the starting system of the car, and a fixed component is also installed on the outer wall of the device body 1 for quickly disassembling and assembling the device body 1.

[0021] The fixing assembly includes a first connecting block 6 and a second connecting block 7. The first connecting block 6 is fixedly connected to the outer wall of the equipment body 1. The outer wall of the second connecting block 7 is provided with two wedge-shaped grooves 701. The outer wall of the first connecting block 6 is fixedly connected to two wedge blocks 601, and the wedge blocks 601 are adapted to be plugged into the wedge grooves 701.

[0022] The fixing assembly further comprises a mounting plate 8 fixedly connected to the outer wall of the second connecting block 7 , a threaded rod 9 is fixedly connected to the middle outer wall of the mounting plate 8 , and a knob 11 is threadedly connected to the outer wall of the threaded rod 9 .

[0023] A locking rod 10 is welded to one end of the threaded rod 9 away from the mounting plate 8 . The outer walls on both sides of the locking rod 10 are provided with threads adapted to the knob 11 , and the outer wall of the locking rod 10 is slidably connected with a stopper 12 .

[0024] The end of the locking rod 10 away from the threaded rod 9 is designed to be hook-shaped.

[0025] The implementation principle of a vehicle alcohol lock device in an embodiment of the present application is as follows: during installation, the bent end of the lock rod 10 is inserted into the air outlet of the automobile air conditioner and hooked on the air guide blade at the air outlet, and then the knob 11 is turned to make the knob 11 rotate on the outer wall thread of the threaded rod 9, thereby driving the knob 11 to move in the direction of the lock rod 10, and the knob 11 pushes the stop block 12 to move toward the air outlet of the air conditioner, so that the stop block 12 abuts against the outside of the air outlet of the air conditioner. At this time, the bent hook at the end of the lock rod 10 cooperates with the stop block 12 to clamp at the air outlet of the air conditioner to fix the assembly, and then the device body 1 drives the second The first connecting block 6 and the wedge block 601 on the first connecting block 6 are inserted into the wedge groove 701 on the outer wall of the second connecting block 7, so that the overall assembly of the device can be completed, and it can be adapted to a variety of occasions, and can be widely used in vehicles such as freight logistics, public transportation, passenger transportation, rental, school buses, and private cars. When using the device body 1, the device body 1 can be directly taken upward, and the device body 1 drives the wedge block 601 to be pulled out of the wedge groove 701 through the first connecting block 6, so that it can be quickly and conveniently used for blowing. After use, the wedge block 601 can be reinserted into the wedge groove 701;

[0026] Before the driver starts the car, the driver must first turn on the alcohol lock device. After the device is preheated for 30 seconds, the driver needs to blow to the blowing end of the fuel cell sensor 2 extending from the outside of the device body 1. Using the fuel cell sensor technology, when the driver's exhaled gas contains alcohol, the fuel cell sensor 2 will quickly capture this signal and start the oxidation reaction. In this process, the alcohol gas is oxidized into acetic acid and water, and electrical energy is released at the same time. The fuel cell sensor 2 will accurately calculate the alcohol concentration according to the amount of electrical energy released. Then the fuel cell sensor 2 converts the detection result into an electrical signal output through the A / D converter 3. The single-chip computer 4 receives the electrical signal output by the A / D converter 3, judges according to the preset alcohol concentration threshold, and sends the judgment result to the interface 401. The interface 401 is connected to the car's starting system through the data line 5. When the single-chip computer 4 judges that the driver's alcohol concentration exceeds the threshold, the interface 401 will send a locking instruction to the starting system through the data line 5, thereby preventing the car from starting and avoiding the occurrence of subjective drunk driving. During driving, the system will also require the driver to perform alcohol testing from time to time to prevent the driver from drinking alcohol during driving.
