Generally speaking, the more common application method is to use the self-propelled power transmission mechanism as the self-propelled unmanned truck; or the self-propelled power source of the self-propelled lifting platform to make up for the failure of the automated transportation system or the automated storage system. It can cover the area where the conveying goods are dead. Although the conventional self-propelled vehicle driven by electric power has the self-propelled function and does not need to consume electric energy, most of its kinetic energy accumulation mechanism is realized by the scroll-type spring mechanism, so that the required components are relatively large.

That is, without increasing the outer diameter of the runner 51, the reciprocating rolling distance of the runner 51 can be increased.

Therefore, after detailed description of the above specific embodiments, the present invention does have the following characteristics:

1. The present invention can indeed make up for the purpose of an automated transportation and replenishment system or an automated storage system that fails to cover the blind area of the conveyed goods.

2. The present invention can indeed realize the function of a reciprocating self-propelled vehicle without electric power driving. Since the force arm of the pendulum pull mechanism is smaller than the force arm, the carriage can be increased in the case of a small moving distance. The purpose of the displacement stroke is more than twice the downward movement distance.

3. The present invention is indeed a lever type unpowered load-carrying reciprocating self-propelled vehicle that can effectively increase the compression/tension displacement stroke distance of the energy storage reciprocating traction mechanism.

4. The present invention can indeed accumulate and release auxiliary kinetic energy by swinging the swing member, thereby improving the performance of the self-propelled vehicle's walking displacement.

The above is only a more feasible embodiment of the present invention, and is not intended to limit the patent scope of the present invention. Any equivalent implementation of other changes based on the content, characteristics and spirit of the following claims is mentioned. All should be included in the scope of the patent of the present invention. The structural features of the invention specifically defined in the claim are not found in similar articles, and are practical and progressive. They have already met the requirements of a patent for invention. The application is filed in accordance with the law. I would like to request that the Bureau of Junction approve the patent in accordance with the law to protect this The legitimate rights and interests of the applicant.
