Description

Angle monitoring device, height measuring mechanism, vehicle body axle connecting structure and vehicle Technical Field The invention belongs to the technical field of vehicles, and particularly relates to an angle monitoring device, a height measuring mechanism, a vehicle body axle connecting structure and a vehicle. Background For vehicles of air suspension systems of commercial vehicles, a height sensor is required to measure the distance between the vehicle frame and the axle, and when the distance between the vehicle frame and the axle is measured to be lower than or exceeds a predetermined height range, the air bag of the air suspension needs to be inflated or exhausted so as to adjust the distance between the vehicle frame and the axle to be within the predetermined height range. However, the height sensor has 3 common principles at present, namely a resistance type, wherein the resistance type comprises a sliding variable resistor, when the distance between an axle and a vehicle body changes, the inductance of the sliding resistor also changes, the inductance is measured by an electronic controller in a very short time and is converted into a height signal, an inductance type, the inductance type converts the measured non-electric quantity (height) into the change of a coil self-inductance L or a mutual inductance M by utilizing the electromagnetic induction principle and then converts the change of the coil self-inductance L or the mutual inductance M into the change of voltage or current for output, and an angle type converts the linear displacement of the height of the vehicle body into the angle change by a mechanical structure part, monitors the angle change by the angle sensor and finally converts the height change value according to the angle change value. For the scheme of angle type, the angle monitoring device that adopts at present is great, and sealed effect is not good, and especially when the vehicle is running under abominable operating mode, dust or mud is permeated in the angle monitoring device easily to finally lead to the damage of angle monitoring device, especially at present commercial car also all tend to the lightweight, and angle monitoring device is great also is unfavorable for commercial car lightweight development. Disclosure of Invention In order to solve the technical scheme, one of the purposes of the invention is to provide an angle monitoring device which has a simple structure, a small size and good sealing performance. In order to achieve the purpose, the angle monitoring device comprises a rotating shaft, a shell and an angle sensing element, wherein a cavity is formed in the shell, an opening is formed in one end of the shell, one end of the rotating shaft penetrates into the cavity through the opening and is in rotary connection with the shell, a shaft sleeve assembly is arranged at the opening, the angle sensing element is arranged in the cavity, the movable end of the angle sensing element is fixedly connected with the rotating shaft in a coaxial mode, and the rotating shaft rotates under the action of external force and drives the movable end of the angle sensing element to rotate so that the angle sensing element outputs rotation parameters of the rotating shaft. The technical scheme of the invention has the beneficial effects that the angle sensing element is integrated in the shell, the rotating shaft passes through the opening and is used as the sensing end of the angle monitoring device, and the shaft sleeve component is arranged at the opening for sealing treatment, so that the shell can protect the angle sensing element, meanwhile, the shaft sleeve component can prevent water stains and dust from entering the shell, and in addition, the whole angle monitoring device is small in size. Based on the technical scheme, the invention can also be improved as follows: Further, the device further comprises a joint male end, wherein the joint male end is arranged at one end, away from the opening, of the shell, and the joint male end is electrically connected with the angle sensing element. The further technical scheme has the beneficial effects that the angle monitoring device can be directly spliced with the carrier with the connector female end, so that the angle monitoring device is more convenient to install on the carrier. Further, an embedded groove is formed in one end, close to the shell, of the male end of the connector, and one end, away from the opening, of the shell is inserted into the embedded groove. The technical scheme has the beneficial effects that the male end of the connector is directly connected with the shell in a plugging manner, so that the whole angle monitoring device is convenient to maintain. Further, one end of the shell, which is away from the opening, is open, the male end of the connector and the shell enclose together to form the cavity, and a first sealing gasket is arranged in the embedded groove.
