Description

Off-road vehicle fuel pressure sensor protection device Technical Field The utility model belongs to the field of automobile sensor protection, and particularly relates to a fuel pressure sensor protection device for an off-road vehicle. Background The gasoline model needs to meet the IV type test (fuel evaporative pollutant test), the VII type test (fueling pollutant emission test) and the fuel system OBD leakage detection test. The fuel pressure sensor is used as a main part of the system OBD leakage detection, and good reliability of the fuel pressure sensor can be ensured, so that leakage of fuel steam is reduced, and pollution of oil gas volatilization to the atmosphere is reduced. However, the off-road vehicle often walks on a rugged road, mud on the road blocks the ventilation holes of the pressure sensor, so that the pressure sensor cannot work normally, and the pressure sensor of the off-road vehicle in the prior art is not specially designed for a special vehicle type. The application provides a solution to the technical problem. Disclosure of utility model The technical problem to be solved by the utility model is to overcome the defects of the prior art, and provide the protection device for the fuel pressure sensor of the off-road vehicle, which is provided with the protection cover on the outer side of the pressure sensor, so that the ventilation holes of the pressure sensor can not be blocked, and the pressure sensor can work normally for a long time. A cross country vehicle fuel pressure sensor protection device, including apron, pressure sensor body and protection casing body, fixedly connected with mount pad in the middle of apron one side, mount pad both sides are fixedly connected with bilateral spring bolt and unilateral spring bolt respectively, mount pad top fixedly connected with pressure sensor body, pressure sensor body upper surface fixedly connected with sensor lid, pressure sensor body both sides are fixedly connected with fixed block and fixed buckle respectively, the slot has been seted up to fixed buckle both sides, unilateral spring bolt lower surface offsets with the fixed block upper surface, bilateral spring bolt is located in the middle of the fixed buckle and offsets with the upper surface of fixed buckle, the top fixedly connected with protection casing body of pressure sensor body, the protection casing body is the casing, logical groove has been seted up to inside one end of casing, logical groove one end offsets with the pressure sensor body, logical groove both sides are equipped with the circular arc elasticity knot with the pressure sensor body, the inside both sides of protection casing body are fixedly connected with elasticity knot and bilateral elasticity knot respectively, the both sides of elasticity knot are pegged graft in the slot and with the lower surface of slot, unilateral knot and offset with the lower surface of fixed block. Preferably, a plurality of ventilation holes are formed between the pressure sensor body and the sensor cover. Preferably, the inner part of the protective cover body is propped against the upper surface of the sensor cover. Preferably, the protective cover body is manufactured by adopting an integral injection molding process. Compared with the prior art, the utility model has the beneficial effects that: According to the utility model, the protective cover is additionally arranged outside the existing pressure sensor, and in a muddy water road area, muddy water can block the air holes, so that the pressure sensor can not accurately read and count, after the protective cover is added, the muddy water is blocked by the protective cover, and the blocking of the muddy water to the air holes is reduced, so that the pressure sensor can work normally.
