The structure is simple and convenient to operate. In actual use, when you need to sit on the seat 101, you need to wear the seat belt in time to sit normally. At the same time, in conjunction with the seat mounting part 1, it can realize automatic control of magnetic locking after detecting that the driver is sitting, to ensure safety. The structural automation effect is better and driving safety is improved. At the same time, the structure adopts a fixed shoulder seat belt 203, which is more stable. Compared with the traditional pull-out seat belt, the structure will not loosen, avoiding the problem that the traditional pull-out seat belt relies on ratchet control and is not stable enough. The seat belt is an important component of the car safety system. The function of the part is to prevent the driver and passengers from being thrown out of the seat in the event of a collision or emergency braking of the car, thereby preventing people from being thrown out due to the inertia of the high speed of the car, and also preventing the body from hitting other objects such as the steering wheel. When the driver sits on the seat 101, he can first lift and pull the protective rod 202, at which time the protective rod 202 can drive the shoulder safety belt 203 to deflect, and then he can sit normally. At this time, the protective rod 202 is released, and under the compression of the torsion spring on the rotating shaft 201, the end of the protective rod 202 is released to align with the anti-slip electromagnet 301. When the driver sits on the seat 101, under the action of gravity, the spring on the sliding column 1031 is compressed, squeezing the load-bearing switch 105, and at this time the load-bearing switch 105 can control the anti-slip electromagnet 301 to electromagnetically absorb the protective rod 202, ensuring stability and safety. ;

[0023] Among them, the pedal limiter 4 includes: a limit mounting plate 401, a plug-in shaft 402 and a baffle 403, the limit mounting plate 401 is an L-shaped structure; the limit mounting plate 401 is used to be fixedly installed on the frame by bolts; the plug-in shaft 402 is slidably plugged on the limit mounting plate 401; the baffle 403 is fixedly installed at the end of the plug-in shaft 402; the plug-in shaft 402 is used to limit the accelerator pedal; the pedal limiter 4 also includes: a tension spring 404 and a limit electromagnet 405, the tension spring 404 is sleeved on the plug-in shaft 402; the end of the tension spring 404 is connected to the plug-in shaft 402; the other end of the tension spring 404 is connected to the side of the limit mounting plate 401; the limit electromagnet 405 is fixedly installed on the side of the limit mounting plate 401 through a bracket; the limit electromagnet 405 is aligned with the plug-in shaft 402; the limit electromagnet 405 is electrically connected to the in-position switch 302; the pedal limiter 4 can be used to control the accelerator pedal to be limited when the seat belt is not worn, so as to avoid the vehicle from running and further ensure safety. This structure adopts a magnetic positioning method, which can improve the current vehicle safety. At the same time, if the driver wears the seat belt normally, non-sensing operation can be achieved. When the seat belt is not worn, the tension spring 404 normally pushes the plug-in shaft 402 to insert into the bottom of the accelerator pedal.

[0024] The lumbar balancing support member 5 includes: an inflatable airbag 501, an air guide tube 502 and a spring 503. Two inflatable airbags 501 are provided, and the two inflatable airbags 501 are respectively fixedly installed on the seat 101; an air guide tube 502 is fixedly connected between the two inflatable airbags 501; two valves are provided on the air guide tube 502; two springs 503 are fixedly installed in the middle of the air guide tube 502, and the two springs 503 are respectively located inside the air guide tube 502; the lumbar balancing support member 5 also includes: a movable piston 504, a fixed electrical connection plate 505 and The movable coil 506 and the movable piston 504 are slidably sleeved in the middle of the airway 502; the movable piston 504 is located between the two springs 503; a fixed power sheet 505 is fixedly installed in the middle of the airway 502; two movable coils 506 are fixedly sleeved on the movable piston 504, and the two movable coils 506 are respectively located on both sides of the fixed power sheet 505; the fixed power sheet 505, the movable coil 506 and the vibration motor 102 are connected in series with the power supply, and the waist balancing support member 5 can be used to support the driver's waist. The working state can improve the riding comfort of the staff. At the same time, the mobile piston 504 can be used to detect the sitting posture of the driver to avoid uneven force on the driver's waist. If one side is subjected to excessive force, long-term driving will easily cause health damage to the spine. The detection of this structure is accurate and direct, and the driver can be directly prompted to avoid the situation that even if the traditional lumbar support achieves the purpose of supporting the driver's waist, it is still easy to cause poor force on one side of the waist in actual use. Long-term poor sitting posture may also affect the driver's driving experience and attention. The bad sitting posture will make the driver feel discomfort or even pain in the waist, thereby affecting the driving comfort and concentration. In an emergency, this discomfort may distract the driver's attention and increase the risk of traffic accidents. If the inflatable airbag 501 on one side is seriously compressed, the movable piston 504 will be displaced under the action of the air pressure and displaced to the inflatable airbag 501 on the side with less pressure, which can drive the movable connecting coil 506 to contact the fixed connecting plate 505. At this time, the circuit of the vibration motor 102 is turned on, and a vibration prompt will be given.

[0025] Embodiment 2, on the basis of embodiment 1, the seat support 6 comprises: a support frame 601, a collision sensor 6011 and a control slider 602, the support frame 601 is rotatably mounted at the bottom of the two support bars 103; a collision sensor 6011 is fixedly mounted on the support frame 601; a row of through holes are respectively provided on both sides of the support frame 601; the control slider 602 is slidably mounted in the middle of the support frame 601; the end of the control slider 602 is a slope structure; the end of the control slider 602 slides and fits the bottom of the support cross plate 104; the support frame 601 and the support cross plate 104 are connected by two tension springs; the seat support 6 also comprises: a control push rod 603, the control push rod 603 is fixedly mounted on the control slider 602; the output shaft of the control push rod 603 is connected to the support frame 601; the collision sensor 6011 is electrically connected to the control push rod 60 3; The control push rod 603 is electrically connected to the driving computer, and the support frame 601 is connected to the support cross plate 104 by two tension springs to maintain the stability of the seat 101. The seat support 6 can be used to adjust the driver's posture when the vehicle collides, which can reduce the risk of injury from the collapse of the car engine. It also helps to reduce the inertial force on the seat belt. If the driving vehicle collides, the driver can lean back in time and lift his legs to reduce the impact force on the body. The control push rod 603 in this structure can be connected in series with the control valve of the car airbag, and can perform risk protection work together to reduce leg injuries. The control slider 602 moves to squeeze the support cross plate 104, and the seat 101 can rotate backwards at this time to help raise the driver's legs and reduce engine collapse damage, especially for cars with shorter seats such as sedans.

[0026] The working principle of this embodiment is as follows: first, bolts are passed through a row of through holes on both sides of the support frame 601, which are respectively provided with a row of through holes, and connected to the vehicle frame. When the driver sits on the seat 101, the protective rod 202 can be lifted and pulled open first, and the protective rod 202 can drive the shoulder safety belt 203 to deflect, and the driver can sit normally. At this time, the protective rod 202 is loosened, and the torsion spring on the rotating shaft 201 is squeezed, and the end of the protective rod 202 is loosened to align with the anti-slip electromagnet 301, and when the driver sits on the seat 101, it will be pulled open by gravity. When the driver is wearing the seat belt, the spring on the sliding column 1031 is compressed, squeezing the load-bearing switch 105. At this time, the load-bearing switch 105 can control the anti-slipping electromagnet 301 to pass the electromagnetic suction protection rod 202 to ensure stability and safety. When the seat belt is not worn, the tension spring 404 normally pushes the plug-in shaft 402 to insert into the bottom of the accelerator pedal. At this time, if the driver wears the seat belt, the anti-slipping electromagnet 301 passes the electromagnetic suction protection rod 202, which will squeeze the position switch 302. At this time, the limit electromagnet 405 will pass the electromagnetic suction plug-in shaft 4 02, the plug-in shaft 402 will drive the baffle plate 403 to move together, release the limit accelerator pedal, and ensure normal driving. When the driver sits on the seat 101, the waist is against the inflatable airbag 501. At this time, if the driver's waist is evenly pressed against the two inflatable airbags 501, the air pressure in the air guide tube 502 is balanced. At this time, the moving piston 504 in the air guide tube 502 is centered. On the contrary, if the inflatable airbag 501 on one side is under more severe pressure, the moving piston 504 will be displaced under the action of the air pressure to the lighter pressure The displacement of the inflatable airbag 501 on one side can drive the mobile connecting coil 506 to contact the fixed connecting plate 505. At this time, the circuit of the vibration motor 102 is turned on, and a vibration prompt will be given. Once the collision module of the car's driving computer detects a vehicle collision through the collision sensor 6011 or sensors at other locations of the vehicle, it can control the airbag valve to open, and also control the control push rod 603 to extend, driving the control slider 602 to squeeze the supporting cross plate 104. At this time, the seat 101 can rotate backward to help raise the driver's legs.
