Abstract

The invention discloses a current sensor for an automobile collision test. The current sensor for the automobile collision test comprises a lower cover and an upper cover plate, wherein the upper cover plate comprises a covering part and an upper magnetic ring mounting part; one side of the upper magnetic ring mounting part is integrally connected with the covering part; a wire inlet is reserved between the other side of the upper magnetic ring mounting part and the covering part; the inner side of the wire inlet is a detecting hole; a lower magnetic ring which can be attracted with an upper magnetic ring, a Hall element which sensing change of the magnetic field of the magnetic rings and a circuit switching device which is connected with the Hall element are arranged in the lower cover; the circuit switching device communicates with an external output device through an output wire; two sliding guide grooves are respectively formed in two sides of the covering part of the upper cover plate; a screw of which the nut diameter is greater than the width of each sliding guide groove penetrates through the sliding guide groove to connect the upper cover plate with the lower cover; the upper cover plate and the lower cover can slide relatively along the sliding guide grooves; and a spring with a steel ball on the top is further arranged on the lower cover and is positioned just below the sliding guide grooves. The current sensor for the automobile collision test is flexible, small and exquisite in structure, convenient to operate, good in locking condition and good in current testing sensitivity, and meets requirements of the automobile collision test.

Description

technical field [0001] The invention relates to a current sensor, in particular to a current detection sensor used in an automobile collision test. Background technique [0002] During the car crash test, the working condition of the motor of the car is related to the performance, safety and maintenance of the car, and the working condition of the motor can be intuitively displayed on the current output. Current sensors currently on the market are either bulky, not securely locked, or not strong enough to be used in crash tests. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a current sensor for automobile crash test with small size, flexible operation, firm locking and good current test sensitivity. [0004] In order to solve the above technical problems, the current sensor for automobile crash test according to the present invention comprises a lower cover and an upper cover, [0005] The upper cover plate i...
