Example Embodiment

[0024] The present invention will be further described in detail below through specific implementation examples in conjunction with the accompanying drawings.

[0025] Refer to figure 1 The I-beam type vehicle dynamic weighing sensor cited in this embodiment includes an I-beam type elastic body 101, a measuring unit 104, a force transmission block 102, and an insulating protective cover 103. There is a penetrating cavity in the I-beam elastic body, and a measuring unit 104 and a force transmitting block 102 are arranged in the cavity. The measuring unit 104 can be received between the force transmitting blocks 102 and is in a pre-tensioned state. In this way, the force distribution of the measuring unit 104 is uniform, so that the weighing result is more accurate. The measurement unit 104 includes an upper electrode 1042, a piezoelectric material 1043, and a lower electrode 1044 in order from top to bottom. In addition, the transverse surface of the insulating protective sleeve ...

Abstract

The invention relates to the technical field of sensors and provides an I-beam type vehicle dynamic weighing sensor. The I-beam type vehicle dynamic weighing sensor comprises an I-beam type elastic body, a measurement unit, power transmission blocks and an insulating protective sleeve, wherein a through cavity is formed in the I-beam type elastic body, the measurement unit and the power transmission blocks are arranged in the cavity, the measurement unit can be accommodated between the power transmission blocks in a pre-tightened mode, the measurement unit comprises an upper electrode, piezoelectric materials and a lower electrode from top to bottom in sequence, the horizontal surface of the insulating protective sleeve is arranged between the upper electrode and the lower electrode, through holes are formed in the horizontal surface of the insulating protective sleeve at equal intervals, the shape of each through hole is matched with that of each piezoelectric material, the insulating protective sleeve is made from an insulating material, and the piezoelectric materials are placed in the through holes. By the adoption of the I-beam type vehicle dynamic weighing sensor, insulation resistance is increased, a measurement result is more accurate, the pressure acting on the measurement unit is reduced, the piezoelectric materials are protected against damage caused by pressure, and service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an I-beam type vehicle dynamic weighing sensor. Background technique [0002] With the continuous and rapid development of science and technology of the national economy, and the road transportation load of my country's logistics industry is getting heavier and busier, the traditional low-speed vehicle weighing method can no longer meet the needs of social development, efficient and fast vehicle dynamic weighing The method has been widely used, and the requirements for the accuracy and reliability of vehicle dynamic weighing results are getting higher and higher. [0003] Previously, the invention patent ZL20131056144.8 that our unit has applied for is also a sensor for road dynamic weighing. It is composed of elastic body and sensitive material, and the sensitive material is fixed in the elastic body cavity with display screws. , by adjusting the pre-tightening force of the scre...
