For example, the air storage chamber is cubic, and the measuring rod inlet is opened at the top of the air storage chamber, and the air inlet is opened at the bottom of the air storage chamber. It can be understood that the The air chamber can also be in other shapes, such as spherical, etc., and the positions of the measuring rod inlet and the air inlet can also be on the side of the air storage cavity or other positions, which will not affect the beneficial effects of the utility model. .
在一优选实施例中,所述气压控制器30包括升压部件31和控压部件32。所述升压部件31通过向所述气室的内部充入气体以提高所述气室的内部气压,实现驱动所述测量杆20作上升运动的目的;所述控压部件32通过调节所述气室的内部气压,以使所述气室的内部气压不超过预设的气压阈值。In a preferred embodiment, the air pressure controller 30 includes a pressure boosting component 31 and a pressure control component 32 . The pressure boosting part 31 increases the internal air pressure of the air chamber by filling gas into the air chamber to achieve the purpose of driving the measuring rod 20 to move upward; the pressure control part 32 adjusts the The internal air pressure of the air chamber, so that the internal air pressure of the air chamber does not exceed a preset air pressure threshold.
所述气压阈值的可选取区间的最大值为,所述测量杆20恰能顶起所述待测汽车时,所述气室的内部气压值;所述气压阈值的可选取区间的最小值为,在未与所述待测汽车接触的情况下,所述测量杆20恰能沿所述测量杆20的轴向作上升运动时,所述气室的内部气压值,所述气压阈值可以是所述气压阈值的可选取区间中的任意值。The maximum value of the selectable interval of the air pressure threshold is the internal air pressure value of the air chamber when the measuring rod 20 is just able to jack up the vehicle to be tested; the minimum value of the selectable interval of the air pressure threshold is , when the measuring rod 20 can just move upward along the axial direction of the measuring rod 20 without being in contact with the vehicle to be tested, the internal air pressure value of the air chamber, the air pressure threshold can be Any value in the selectable interval of the air pressure threshold.

The inflator is connected to the air chamber through the vent pipe, and the vent pipe is provided with a number of air holes corresponding to the air pressure threshold for pressure relief, for example, according to the air pressure in an optional interval of the air pressure threshold The value A opens the corresponding number of air holes. The inflator fills the interior of the air chamber with gas, and part of the gas will leak out from the air hole when passing through the ventilation pipe. At this time, because the internal pressure of the air chamber does not reach the air pressure value A, that is, The internal air pressure of the air chamber does not reach the preset air pressure threshold, gas is filled into the air chamber to increase the internal air pressure of the air chamber, and the internal gas of the air chamber pushes the measuring rod 20 to make an upward movement; When the second end of the measuring rod 20 touches the car to be tested, the second end is blocked by the car to be tested so that the measuring rod 20 stops the upward movement, and the internal air pressure of the air chamber further rises. High, reaching the air pressure value A, that is, reaching the preset air pressure threshold, the speed at which the gas is filled into the interior of the air chamber and the speed at which the internal gas in the air chamber leaks out through the air hole of the ventilation pipe reach Equilibrium, the internal air pressure of the air chamber remains stable. It prevents that the internal air pressure of the air chamber is too low to drive the measuring rod 20 to move upward, and prevents the measuring rod 20 from jacking up the vehicle to be tested due to the excessive internal air pressure of the air chamber. , thereby affecting the accuracy of the measurement results, which further improves the reliability of the gap measurement device 100 and the credibility of the measurement results.

The air pressure controller increases the air pressure of the air chamber, and driven by the internal gas of the air chamber, the measuring rod moves upward along its own axis. Until the second end of the measuring rod is in contact with the vehicle under test, the force of the vehicle under test received by the second end makes the measuring rod stop the upward movement and remain at the current position, by measuring The distance between the top of the measuring rod and the bottom plane of the base can be used to obtain the minimum ground clearance of the vehicle to be tested, and there is no need for staff to enter and exit the space under the vehicle to be tested during the measurement process, which reduces the The workload of measuring the minimum clearance of the car from the ground, and because the car to be tested can be directly parked on the ground, the gap measuring device is placed on the bottom of the car to be tested to complete the detection. The vehicle to be tested can be conveniently and accurately placed on the same horizontal plane, which improves the accuracy of gap measurement.
以上所述是本实用新型的优选实施方式,应当指出,对于本技术领域的普通技术人员来说,在不脱离本实用新型原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也视为本实用新型的保护范围。The above is a preferred embodiment of the present utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present utility model, some improvements and modifications can also be made, these improvements and modifications It is also regarded as the protection scope of the present utility model.
