Description

Technical Field

[0001] This utility model relates to the field of automobile model technology, specifically to an automobile model chassis structure. Background Technology

[0002] The vehicle model includes an electric drive system, which executes vehicle motion control commands and performs actions such as steering, acceleration, and deceleration based on the control command signals. This is a mature technology in remote-controlled car models.

[0003] Currently, all the model remote control cars in the industry have the same layout for the chassis components: the motor is on one side and the battery is on the other (as shown in the picture below). For example, the electronic speed controller, servo motor (also known as a servo motor) and receiver are arranged haphazardly without a standardized layout. This arrangement makes it impossible to achieve left-right balance. In actual operation, the center of gravity of the remote control model car will tend to the heavier side, which is not conducive to vehicle control. Utility Model Content

In addition, the chassis has a neat design, and all kinds of electronic wires are neat and orderly, which is more conducive to maintenance and repair.

[0013] 2. This utility model improves the stability of the chassis's center of gravity by setting a first rotating shaft, a first bevel gear, a second rotating shaft, and a third bevel gear. The first bevel gear on the first rotating shaft and the third bevel gear on the second rotating shaft are symmetrically arranged on both sides of the central axis of the car chassis.
