Description of the Invention: [Technical Field] The present invention relates to a vehicle body collision cushioning device, and more particularly to a cushioning device combining a stretching mechanism and a rod structure, which has a folding/stretching function, and can be normally used. Fitted in a compact body shape, it expands to become an effective collision cushioning device, allowing the vehicle to take care of the body's light weight and collision resistance, and is easy to recycle or even reuse. [Prior Art] The compact and lightweight vehicle has the advantages of energy saving, small parking space, flexible maneuverability, and high passenger load rate. It is one of the trends in the future of vehicle evolution. However, the compact body has almost no additional buffer space to absorb the impact and energy of the vehicle in an accidental collision, and the safety of the vehicle body collision. In general, when a car is hit, it usually uses the deformation of the structure of the car body (steel plate, bumper, and main beam of the chassis) to absorb the impact energy. The structure must be Φ strong enough and flexible, and the vehicle exterior design is usually It is divided into three parts: the engine room, the passenger cockpit and the luggage room. Among them, the engine room and the luggage room are most often used as the collapse buffer space for collision. However, in the future, vehicles are demanded for miniaturization and electrification. The body size is small and there is no engine room as a buffer space. Therefore, based on the dual requirements of vehicle miniaturization and collision safety, vehicle design must be more prudent to ensure driving and passengers. The safety of personnel. As far as the conventional patents are concerned, for example, the Republic of China Patent Publication No. 1268237 "Automobile anti-collision spring structure car body" proposes a buffer device that utilizes elastic force and deformation to absorb impact force, which is combined with a plurality of strong springs 5 1336668 a bumper (also known as an anti-collision body), the strong spring is a cylindrical ring spring with a gradually widened radius and an intermediate dimple, and the inner edge thereof is provided with a plurality of flexure columns along the curved surface of the spring, when the automobile collides The outer part of the bumper can be moved inward due to the compression of the spring, and the special design of the spring can withstand a large force and absorb a large impact force. However, the buffer structure has a large volume and is relatively unfavorable for the application of small vehicles. For example, in U.S. Patent No. 5,971, 451, "Vehicle bumper", a buffer device using a spring-applying magnetic force is proposed, which is provided with a compression-resistant magnetic block in a buffer body, and an appropriate number of buffer bearings are arranged between the compression-resistant magnetic blocks. a seated rod, and an appropriate number of externally connected rod members; and an array of mechanical buffer members (springs) disposed at the buffer base portion, pivoted through the mechanical buffer member And the contact portion of the movable end magnetic block which is repelled by the same pole surface is provided in the corresponding portion of the diamagnetic block region; a doubled anti-pressure product buffer is formed between the inner rod and the outer contact rod; The structure of the patent is complicated. If the magnetic pole repulsive action is increased, the magnetic block must be enlarged, not only the weight of the buffer device is increased, but also the weight of the vehicle body is increased. For example, in US Patent No. 7,528,191, "Air bag system incorporated into motor vehicle bumper", an extendable bumper using a balloon is proposed. When the car is about to collide, the sensor transmits a signal to the gas-filled cylinder after the collision signal is received. The gas inflates the air bag and allows the front split plate to spread forward to obtain a buffer space and enhance the cushioning effect. Although this method can be applied to small and light vehicles, the airbag system is complicated and has problems such as high cost and service life. For example, the Republic of China Patent Notice M267115 "Capable and Dispersive Force 6

However, the patent is in two; two arms, two auxiliary arms, and enough to install, which is not conducive to the application of the car body requires sufficient space, such as the US patent 6,776,718 Lu "to make a retractable companion: 1 ... bumper and The "heart" danger rod, when the energy absorption shaft is connected to the energy absorption shaft by the system, the safety rod is elongated, and the absorption shaft absorbs the impact energy by using the absorption shaft. Vertebrae, ^ I扪 used April space, in addition, the design of the shrinking bumper still occupies the moment when the car body is hit and the end of the movement is two, if it can't be different. The nature of this is the same as the general insurance, for example, the Republic of China Patent Publication No. 327383, "Gas Patent and the above-mentioned U.S. Patent No. 6,716,718, "Vehicle h, "V". μ = 'The piston that uses the air pressure to push the buffer, so that:: Drought: c:" or shrink into the body.

Or discharge. However, the concept of using the engine exhaust is not applicable to electric vehicles, and if the vehicle is connected to the air pressure system, it will inevitably add extra weight. Similarly, the air pressure reaction time is slow, such as when the vehicle body cannot be hit. The elongation action is completed, and its performance is the same as that of a normal normal bumper.
