Abstract
Description
BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an automobile frame, and more particularly, to an automobile frame capable of varying the position of a center of gravity in various ways to enhance energy efficiency, To an automobile frame which can alleviate an impact amount of the automobile.
In general, a frame is a basic structure of a chassis of an automobile. A chassis is a state in which a minimum mechanical device necessary for running a vehicle is installed, and the chassis can be driven only by the chassis. In other words, a frame is a basic structure or frame that forms a chassis by mounting an engine, a suspension, a brake, a clutch, a wheel, a transmission, a suspension, and a steering device.
The development of conventional automobiles has been linked to technological advances since the first traffic accidents, and safety belts and airbags emerged. The research on the increase of the shock absorbing capacity is not limited in that the degree of safety of the driver is guaranteed according to how much the car absorbs the shock when the vehicle collides.
Accordingly, the concept of the crumbling zone of the car, namely the crumble zone, was established among the safety measures, and it was realized by applying it to the automobile. This means that the space occupied by the driver or the passenger is protected only when the vehicle is broken, and it is interpreted in the sense that it is safe to be broken down to a small extent. In other words, The importance of the crumb zone has been fully emphasized in the car collision test to demonstrate safety until now.
In recent years, environmental problems, energy efficiency and safety have become more prominent in the automobile market, Efforts have been made to reduce weight by using high-lightweight materials such as engineering plastics and carbon fibers. As a result, electric vehicles have received much attention in the future automobile market, and the frame structure has changed a lot. By using this technology, research on high-light-weight materials is more focused on the center of gravity of the vehicle that affects safety and energy efficiency .
Electric vehicles have various types of frames ranging from passenger cars to freight cars, and various changes have been made in the freight cars according to the position or purpose of the cargo area. In addition, a battery capable of storing electricity is mounted, and an electric motor is used to generate a driving force.
Therefore, in the frame of the automobile using the conventional carbon fuel, the structure is excessively changed in one direction for the safety of the driver and there is no space for mounting the battery separately, The center of gravity is relatively concentrated by the seat, and a car centered on the cargo like a freight car has a problem that the center of gravity is dispersed.
In addition, the frame for a conventional battery automobile is combined with a load cell capable of placing a battery in an existing frame, but it is impossible to simply combine the load cell with a buffer material inside the load cell.
Accordingly, although the conventional frame for an electric vehicle is formed so as to enable the battery to be seated, a problem that the electrolyte is leaked or short-circuited due to the impact amount of the automobile being transmitted to the battery when the vehicle collides occurs, Respectively. In addition, in order to increase the energy efficiency, the weight of the frame can withstand the weight of the motor and the battery, and the frame structure of the automobile which can mount the battery is required.
The use of an excessively lightweight material of the automobile makes it impossible to properly absorb the shock when the vehicle collides with the vehicle, thereby making the safety of the driver unstable, solving the problem that the center of gravity is shifted in one direction depending on the structure of the vehicle and the shape of the cargo, The present invention solves the problem of not being able to adapt to diversification such as the capacity or replacement cycle of the battery because there is no space for mounting the battery in the automobile using the main driving force, The present invention provides a vehicle frame which can be increased in size.
A frame including a side member formed in the longitudinal direction of the automobile and a case slidable along the side member, wherein the center of gravity of the automobile is changed according to the movement of the case.
According to the structure of the present invention, the safety of the driver is enhanced, the battery can be replaced, the utility such as the auxiliary battery is increased, and the number of batteries used can be adjusted. Further, since the center of gravity of the automobile can be moved by using the weight of the battery, the fuel efficiency and the operation performance of the automobile are improved and the automobile can be applied to various types of vehicles with one frame. Enables optimum driving and utilization in various environments. In addition, the case in which the battery is seated in the event of an automobile collision is provided separately from the main frame receiving the impact from the impact, so that not only the battery is protected from impact to the outside but also the driver can be protected.
