Crank-type wireless remote control device and excavator toy controlled by same

Abstract

The invention discloses a crank-type wireless remote control device which comprises a digital remote control emission board, a counter, a timing circuit board and a timing display, wherein the digital remote control emission board comprises an emission master board as well as an action control module and an emission module connected with the emission master board, the action control module comprises a forward-walking, backward-walking, leftward-walking and right-walking control module, a bucket rod and bucket action control module, and a central rotation and movable arm action control module, the emission module is used for sending out actuating signals of an eight-direction walking rocker potentiometer, a bucket rod and bucket action rocker potentiometer, and a central rotation and movable arm action rocker potentiometer, and the emission module further comprises an emission module antenna. The crank-type wireless remote control device is easy and flexible to operate, and is sturdy and durable. The invention further discloses an excavator toy. After being provided with a bucket rod steering engine, a bucket engine, a movable arm steering engine and a central rotation gear limiting device, the excavator toy has the advantages that the excavating action is smooth, the shell clamping is avoided during rotation of the machine body, the wheel clamping is avoided during walking of a caterpillar track, and a battery can be replaced in time.

Description

technical field [0001] The invention relates to a device of a rocker type wireless remote control excavator toy and the excavator toy remotely controlled by the device. Background technique [0002] Existing excavator toys are equipped with hand-held ordinary wireless remote control devices, or desktop wireless remote control devices with cumbersome and complicated operations. For commercial use. [0003] The action of the boom, arm, bucket and slewing device of the existing excavator toys on the market relies on complex gear drives. Stuck, the wheels are easily stuck when the track is walking on the sand, Jue Mingzi and other particles, causing the motor to run overloaded, and it is very likely to burn out the motor regulator and motor, which affects the playing effect of the players, and the damaged motor is not damaged. It is easy to maintain. In addition, there is a lack of low-voltage battery alarm, and the battery is over-discharged. [0004] The arm and the bucket ...

[0003] The action of the boom, arm, bucket and slewing device of the existing excavator toys on the market relies on complex gear drives. Stuck, the wheels are easily stuck when the crawler is walking on the sand, Jue Mingzi and other particles, causing the motor to run overloaded, and it is very likely to burn out the motor regulator and motor, which affects the playing effect of the players, and the damaged motor is not damaged. It is easy to maintain. In addition, there is a lack of battery low-voltage alarm, and the battery is over-discharged. The service life of the battery will be greatly shortened after over-discharge, and it will cause serious damage to the battery.

[0004] Excavator toys sold in the existing market have poor movement of sticks and buckets, and faults occur from time to time during operation. Many faults occur, which greatly reduces the player's interest in playing.
