Description

Technical Field

[0001] The utility model relates to the technical field of distance and speed measuring instruments, and particularly relates to a distance and speed measuring instrument. Background Technique

[0002] A laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to a target. The measurement range of a laser rangefinder is 3.5 to 5000 meters. According to the ranging method, it is divided into a phase method rangefinder and a pulse method rangefinder. A pulsed laser rangefinder emits a beam or a series of short pulsed laser beams towards the target during operation. The laser beam reflected by the target is received by a photoelectric element, and a timer measures the time from the emission to the reception of the laser beam to calculate the distance from the observer to the target. A phase method laser rangefinder detects the distance by detecting the phase difference that occurs when the emitted light and the reflected light propagate in space.

[0003] However, at present, laser rangefinders or laser ranging modules on the market can only achieve ranging or roughly estimate the speed by the distance change of the measured object per unit time, with low speed measurement accuracy and relatively harsh usage conditions. Content of the Utility Model

[0004] The purpose of the utility model is to provide a distance and speed measuring instrument, which has the advantages of being able to synchronously perform distance measurement and speed measurement operations on an object during use, effectively improving the overall speed measurement operation accuracy.

[0005] To achieve the above purpose, the utility model provides the following technical solution: a distance and speed measuring instrument, including a rangefinder main body, an eyepiece assembly, a transmitting objective lens assembly, and a receiving objective lens assembly. A prism assembly is arranged in the middle of the rangefinder main body. A laser emitting assembly is fixedly installed in the middle of the bottom of the rangefinder main body. A laser receiving assembly is fixedly installed at the right end of the rangefinder main body. A millimeter-wave radar front-end assembly is fixedly installed at the lower right end of the bottom of the rangefinder main body and below the laser receiving assembly. A display screen assembly is fixedly installed at the left end of the rangefinder main body. A distance and speed measurement circuit assembly is fixedly installed on the back of the rangefinder main body.

[0008] As a preferred solution, the millimeter-wave radar front-end component includes a radar RF antenna and a millimeter-wave radar chip.

[0009] As a preferred solution, a rubber sealing ring is fixedly connected to the middle end of the eyepiece assembly, and a dust-proof cover is threadedly connected to the left end of the eyepiece assembly.

[0010] As a preferred solution, a positioning post is fixedly connected to the back of the rangefinder body, a positioning hole is formed on the surface of the ranging and speed-measuring circuit component, and the surface of the positioning hole is movably connected to the surface of the positioning post.
