The electric cylinders 33 are provided with two groups, the electric cylinders 33 are symmetrically arranged about the lifting block 30, two electric cylinders 33 are arranged in each group, and the two electric cylinders 33 are respectively arranged at two ends of the lifting block 30.
As shown in fig. 2 and 3, the open end of the equipment box 10 is fixedly provided with an open shielding block 12, and a perforated plate 14 through which air passes is provided near the inner wall of the equipment box 10, and the extending direction of the perforated plate 14 is the same as the rotating axial direction of the turning plate 34. The side of the opening shielding block 12 facing the equipment box 10 is provided with a concave groove 40, and the inner wall of the concave groove 40 is in sliding abutting contact with the end of the turnover plate 34 facing the opening of the equipment box 10. The opening shielding block 12 is provided with a pressing cavity 43 between the perforated plates 14 on two sides, a pressing rod 41 is slidably arranged in the pressing cavity 43, the joint of the pressing rod 41 and the pressing cavity 43 is sealed, the end part of the pressing rod 41 away from the pressing cavity 43 extends into the concave groove 40, and one end of the pressing rod 41 extending into the concave groove 40 is in a curved surface. The part of the turnover plate 34 extending into the concave groove 40 can be abutted with the pressing rod 41, the middle bottom of the pressing cavity 43 is communicated with a second air duct 42, the second air duct 42 is a flexible pipe, the other end of the second air duct 42 penetrates through the sliding block 22 and the supporting rod 21 to extend into the space for installing the limiting spring 27 in the inertia sphere 20, and a large amount of air is filled in the pressing cavity 43. When in use, the connecting frame 11 is horizontally and fixedly connected with the vehicle body through the threaded connecting piece, so that the equipment box 10 is fixed with the vehicle. When the inversion plate 34 is inverted and brought into contact with the pressing rod 41, the pressing rod 41 is slid toward the inside of the pressing chamber 43 with continued inversion of the inversion plate 34, and the air pressure in the pressing chamber 43 is increased. Because the second air duct 42 communicates the pressing cavity 43 with the air environment inside the inertia sphere 20, the air pressure inside the inertia sphere 20 is increased at this time, and at this time, because the support rod 21 is fixed in the vertical direction, the air pressure inside the inertia sphere 20 is increased and acts on the inertia sphere 20, so that the vertical downward pressure of the inertia sphere 20 is increased, and the stability of the inertia sphere 20 in the vertical direction is further improved.
The equipment box 10 is fixedly connected with the vehicle through a connecting piece, so that the whole equipment box 10 can move together with the vehicle, and the inertia ball 20 can horizontally move in the space between the turnover plate 34 and the inner wall of the equipment box 10. When the vehicle is traveling straight, the inertia ball 20 cannot move horizontally in the space between the roll-over plate 34 and the inner wall of the equipment box 10 due to the friction force, and the sensing structure does not receive the pressure action of the inertia ball 20, and the sensing structure does not generate an electric signal. When the vehicle track deviates, the inertia ball 20 slides along the opposite direction of the vehicle deflection direction under the inertia effect, namely, the overturning plate 34 slides between the inner wall of the equipment box 10 and generates pressure with the sensing structure, and the sensing structure generates an electric signal and then transmits the electric signal into the control terminal 13. When the driver drives the vehicle normally by the above process, the sensing structure is stabilized by the pressure of the inertia ball 20 and does not generate an electric signal, and when the driver changes direction rapidly and frequently, the inertia ball 20 applies pressure to the sensing structure frequently. At this time, the sensing structure frequently generates an electric signal and transmits the electric signal to the control terminal 13, and the control terminal 13 can judge and analyze the driving state of the driver at this time after receiving the electric signal, thereby achieving the purpose of monitoring the driving behavior of the driver in real time. The mode of generating pressure by adopting mechanical collision does not need to debug and correct the sensor control system according to different vehicle models before installing the analysis equipment, only the equipment box 10 is required to be installed on a vehicle, the butt joint adaptation with the vehicle control system is not required, the analysis equipment can be quickly dismantled after being used, and meanwhile, the safety and the integrity of the vehicle are not influenced.
Because the sliding block 22 only can horizontally slide in the sliding cavity 26, the supporting rod 21 and the sliding block 22 are hard connected at this moment, and the limiting spring 27 vertically presses the inertia ball 20 under the action of elasticity, so that the inertia ball 20 always keeps in a contact state with the overturning plate 34, and compared with the situation that the inertia ball 20 is only placed on the overturning plate 34 and the inertia ball 20 after pressure is applied is more stable, the stability of the inertia ball 20 when a vehicle passes through a bumpy road surface is improved, and the situation that the inertia ball 20 mistakenly senses a sensing structure when the vehicle passes through the bumpy road surface is avoided.
The synchronous connecting block 24 is arranged in the sliding groove 28 in a sliding way, the pressure sensor 25 is arranged on one side of the synchronous connecting block 24 facing the inertia ball 20, the pressure sensor 25 is connected with the inertia ball 20 through the pressure spring 23, the inertia ball 20 can be stably kept between the two pressure sensors 25 under the action of the elasticity of the pressure spring 23, therefore, the stability of the inertia ball 20 in the moving process of a vehicle is improved, after the vehicle is subjected to tight steering, the inertia ball 20 moves towards the opposite direction of the vehicle steering under the action of inertia, meanwhile, the inertia ball 20 drives the sliding block 22 to slide in the sliding cavity 26 through the supporting rod 21, the pressure spring 23 on the side is compressed at the moment, so that the pressure of the pressure spring 23 on the pressure sensor 25 is changed, the pressure sensor 25 generates an electric signal to be transmitted into the control terminal 13, and the elasticity of the pressure spring 23 in the process can keep the stability of the inertia ball 20 and also transmit the pressure to the pressure sensor 25 to generate the electric signal, so that the purpose of monitoring the running state of the vehicle is achieved.
When the turnover plate 34 rotates along the rotation axis towards the direction close to the air bag 35, because the included angle between the turnover plate 34 and the vertical inner wall of the equipment box 10 changes, the vertical height of the synchronous connecting block 24 changes, at the moment, a gap exists between the synchronous connecting block 24 and the abutting wall body at the upper side of the sliding groove 28, when the vehicle bumps, the situation that the synchronous connecting block 24 jumps is likely to happen, but at the moment, the air bag 35 is compressed by the turnover plate 34, so that air in the turnover plate 34 is led into the air pressure cavity 37 through the first air duct 36, the air pressure in the air pressure cavity 37 is increased, the abutting block 38 moves towards the direction of the synchronous connecting block 24, the abutting block 38 always abuts against the synchronous connecting block 24, and pressure is given to the synchronous connecting block 24, so that the stability of the synchronous connecting block 24 is improved, the stability of the pressure sensor 25 is further improved, and the situation that the accuracy of receiving the pressure change by the pressure sensor 25 is influenced by dislocation of the pressure sensor 25 and the inertia ball 20 is prevented.
The lifting block 30 is driven to rise or fall along the vertical direction by the electric cylinder 33, the limiting rod 32 can prevent the lifting block 30 from deflecting in the movement by sliding in the limiting groove 31, the stability of the lifting block 30 is improved, when the lifting block 30 rises or falls, the included angle between the turnover plate 34 and the vertical inner wall of the equipment box 10 can be changed, so that the height of the inertia sphere 20 is changed, when the included angle between the turnover plate 34 and the inner wall of the equipment box 10 is increased, the width below the inertia sphere 20 is reduced due to the fact that the inertia sphere 20 is spherical, the inertia sphere 20 moves upwards at the moment, and otherwise moves downwards. Because the included angle between the overturning plate 34 and the inner wall of the equipment box 10 is changed, so that the included angle between the overturning plate 34 and the gravity direction of the inertia ball 20 is also changed, the pressure of the abutting surface of the inertia ball 20 and the overturning plate 34 is changed at the moment, so that the friction force between the inertia ball 20 and the overturning plate 34 is changed, when the friction force between the inertia ball 20 and the overturning plate 34 is increased, the stability of the inertia ball 20 is improved, the influence of the steering inertia of a vehicle on the inertia ball 20 is reduced, otherwise, the stability of the inertia ball 20 is reduced, the influence of the steering inertia of the vehicle on the inertia of the inertia ball 20 is improved, and the friction force between the inertia ball 20 and the overturning plate 34 can be automatically regulated by the analysis equipment according to different vehicle models and vehicle speeds in the regulation process, so that the working condition range of the vehicle, which can be adapted by the analysis equipment, is improved.
Through setting up a plurality of electric jar 33, make lifting block 30 rise and descend the in-process, lifting block 30 both ends can be synchronous and keep stable, are favorable to the stability of upset board 34 to improve the stability of inertia spheroid 20, further improved the degree of accuracy of analytical equipment monitoring driving action.
The control terminal 13 is surrounded by the connecting frame 11, so that the control terminal 13 is protected, the control terminal 13 is prevented from being damaged after foreign matters are introduced into the position of the control terminal 13, and the safety of the control terminal 13 is improved. Simultaneously, the gas environment inside the equipment box 10 is communicated with the gas environment outside the equipment box 10, when the analysis equipment is installed in the engine cabin, air rapidly flows through the inside of the equipment box 10, so that the heat dissipation of the pressure sensor 25 can be normal, and the service life of the pressure sensor 25 is effectively prevented from being influenced by the high temperature of the engine.
