Manual drive toy car based on gear drive

Technical Field

The invention belongs to the technical field of toy vehicles, and particularly relates to a manually-driven toy vehicle based on gear transmission.

Background

At present, most of the existing toy vehicles adopt batteries as energy sources to drive the toy vehicles to normally move; however, the battery mainly contains iron, zinc, manganese and the like, and in addition, contains a trace amount of mercury, which is toxic. The mercury in the waste battery has no threat to the environment, has low volatilization temperature and is a heavy metal with larger toxicity. The soil in many places also contains a trace amount of mercury, when the waste batteries are discarded by users in the environment at will, the trace amount of mercury in the batteries can enter underground water under the action of a long time, and when people use underground water containing mercury, the health of the users can be greatly influenced; it is therefore desirable to design a manually driven toy vehicle based on gear transmission that takes into account the play function of the toy vehicle while also taking into account environmental conditions.

The invention designs a manual driving toy car based on gear transmission to solve the problems.
