Problems solved by technology

[0002] At present, in the installation process of the oil level sensor, the oil level sensor is directly installed on the fuel tank through the flange. The fuel tank contains a lot of fuel, and the fuel has a certain fluidity. When the road conditions are poor, the fuel will have more impact on the fuel level sensor, which will cause damage to the rod or floating body of the fuel level sensor, reducing the service life of the fuel level sensor and increasing the cost of use.

Embodiment Construction

[0014] The specific implementation manners of the present invention will be further described below in conjunction with the drawings and examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0015] Such as figure 1 As shown, the present invention is a fuel tank oil level sensor. The oil level sensor device installed on the fuel tank 1 includes a circuit box 2, a signal line 3, a flange 4, and a rod body 5. A floating body is provided on the side of the rod body. Said floating body comprises a rugby ball-shaped float 6 arranged vertically, and the axial position of said float is pierced with a floating column 7, said float is connected with said floating column in rotation, and said floating column slides through swing arm 8 and rod body. The contact piece 9 is connected.

[0016] A buffer sleeve 10 is sheathed on the outside of the rod body, ...

Abstract

The invention discloses an oil level sensor of a fuel tank. The oil level sensor device installed on the fuel tank includes a circuit box, a signal line, a flange, and a rod body. A floating body is arranged on the side of the rod body, and the floating body includes a vertically arranged A rugby ball-shaped float, the axial position of the float is pierced with a floating column, the float is rotatably connected to the floating column, and the floating column is connected to the sliding contact piece in the rod body through the swing arm. The float of the fuel level sensor of the present invention is a rugby ball shape with a smooth appearance arranged vertically, and the float is connected to the floating column in rotation. When the impact force in the front and rear direction hits the float, the smooth surface and rotatable feature of the float can buffer or release more impact force and improve the service life of the float.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a fuel tank oil level sensor. Background technique [0002] At present, in the installation process of the oil level sensor, the oil level sensor is directly installed on the fuel tank through the flange. The fuel tank contains a lot of fuel, and the fuel has a certain fluidity. When the road conditions are poor, the fuel will have more impact on the fuel level sensor, which will cause damage to the rod or floating body of the fuel level sensor, reducing the service life of the fuel level sensor and increasing the cost of use. Contents of the invention [0003] The object of the present invention is to overcome the defects in the prior art and provide a fuel tank oil level sensor with simple structure, impact resistance, non-damage and prolonged service life. [0004] In order to achieve the above object, the technical solution of the present invention is to design an oil leve...
