A navigator with the function of speed measurement and follow-up

Abstract

The invention discloses a navigator with the function of speed measurement and follow-up shooting, which comprises a base provided on the lower side of the body, a powerful suction cup is fixed symmetrically on the front and back sides of the lower side wall of the base, and a transmission cavity is arranged inside the body. The lower side wall of the transmission chamber is provided with an auxiliary groove communicating with the outside of the body, the upper side wall of the base is fixed with a fixed shaft extending into the transmission chamber, and the fixed shaft is arranged in the auxiliary groove The present invention is easy to operate and low in manufacturing cost, and can drive the whole body to rotate around the fixed shaft through the meshing of the racks on the upper and lower sides with the sector gear, so that the speeding camera follows the speeding vehicle to move and shoot, The super-speed camera can be moved upwards through the helical cooperation between the screw rod and the threaded hole to increase the shooting field of view.

Description

technical field [0001] The invention relates to the technical field of car navigation, in particular to a navigator with the function of speed measurement and follow-up shooting. Background technique [0002] At present, the target of the existing speed-measuring vehicle or the hand-held radar speed-measuring gun of the traffic police is too obvious, so that some speeding vehicles can be found far away, and slow down in advance. If ordinary vehicles are equipped with a navigator with a speed measurement function, the traffic police can perform speed measurement operations without being discovered, but the navigators on the market are all fixed and cannot track and shoot speed measurement vehicles. Set up a cooling device. When the sun is strong, the internal temperature of the navigator is very high. The performance of the navigator under high temperature for a long time is unstable and the service life is reduced. Contents of the invention [0003] The object of the pres...

Problems solved by technology

[0002] At present, the target of the existing speed measuring vehicle or the radar speed measuring gun held by the traffic police is too obvious, so that some speeding vehicles can be found far away, and slow down in advance, and continue to speed up after leaving the speed measuring point, making it impossible to educate and punish them

If ordinary vehicles are equipped with a navigator with a speed measurement function, the traffic police can perform speed measurement operations without being discovered, but the navigators on the market are all fixed and cannot track and shoot speed measurement vehicles. Set up a cooling device. When the sun is strong, the internal temperature of the navigator is very high. The performance of the navigator under high temperature for a long time is unstable and the service life is reduced.
