  "abstract": "An elastic member can implement functions of buffering and shock absorption while effectively supporting a vehicle body. On end of the elastic member is turned and bent towards the other end, and passes through the body of the elastic member. The turned and bent part forms a curled portion (3). Portions of the curled portion (3) extending towards two ends form a first arm (1) and a second arm (2). The curled portion (3) pre-stores deformation of a material to integrate an elastic capability of the material and specifically gather a weak elastic capability of a rigid material, thereby obtaining a higher elastic bending moment, and providing functions of buffering and shock absorption while bearing is provided. For a flexible material, the flexible material can be restrained by using the curled portion to increase rigidity and reduce randomness of deformation of the flexible material, thereby combining flexibility and rigidity.",
  "claims": [
    "1. An elastic member, wherein one end of the elastic member is curled towards the other end, and penetrates a body of the elastic member, and a portion being curled forms a curled portion, and portions extending from the curled portion to the two ends of the elastic member form respectively a first arm and a second arm, and both of the first arm and the second arm are bearing arms, and the geometrical configuration and size of each of the first arm and the second arm have no relationship with the size of a space for penetrating the body of the elastic member, wherein the one end of the elastic member is curled towards the other end a plurality of times and successively, and each curling penetrates the body of the elastic member so as to form a plurality of curled portions sequentially connected between the first arm and the second arm.",
    "2. The elastic member according to claim 1, further comprising a buffer member configured to adjust the curling deformation of the curled portion.",
    "3. The elastic member according to claim 2, wherein the buffer member comprises a rubber element disposed in a hollow region of the curled portion.",
    "4. The elastic member according to claim 2, wherein the buffer member comprises a spring, and two ends of the spring are connected to the first arm and the second arm respectively, so as to tension the first arm and the second arm inward and further position the two arms.",
    "5. The elastic member according to claim 1, wherein the plurality of curled portions are symmetrically distributed with respect to a center line of the elastic member.",
    "6. The elastic member according to claim 1, wherein the plurality of curled portions are different from each other.",
    "7. The elastic member according to claim 1, wherein at least one curled portion in the plurality of curled portions is curled spirally.",
    "8. The elastic member according to claim 1, wherein the first arm and the second arm are different in size, and each of the first arm and the second arm is provided with a bearing end.",
    "9. The elastic member according to claim 8, wherein an end of the first arm and/or an end of the second arm is/are curled inward to form the bearing end.",
    "10. The elastic member according to claim 1, wherein the body of the elastic member is provided with an insertion opening for one end of the elastic member to penetrate, and a first stopper capable of abutting against the insertion opening is provided in the curled portion; and/or a second stopper capable of abutting against an outer wall of the curled portion is provided outside the curled portion.",
    "11. The elastic member according to claim 10, wherein the first stopper is a stopper blocker in cooperation with an end face of the insertion opening; and the second stopper has a braking curved surface fitting against the outer wall of the curled portion.",
    "12. The elastic member according to claim 1, wherein the elastic member is made of a rigid material."

  "description_excerpt": "The present application relates to the technical field of buffer devices, and particularly to an elastic member in a buffer system. The present application further relates to an elastic structural member capable of achieving bearing capability combining rigidity and flexibility.\n\nThere are many occasions in the conventional technology where a buffer member needs to be provided for buffering a load, for example, a suspension system of an automobile, a scraper in a scraper conveyor for transportation in underground coal-mining, a buffer device of a safety belt etc. Only an automobile suspension system is described below as an example.\n\nA suspension system is a generic term of all force transmission connectors between a frame and an axle or a wheel of a vehicle such as an automobile, and is used for transmitting force and moment between the wheel and the frame, buffering impacts that transmitted to the frame or body of the vehicle from an uneven road, and absorbing shocks caused by this, so as to smooth the traveling of the vehicle.\n\nIn the conventional technology, an automobile leaf spring is a most conventional elastic element in a suspension system. Since it has advantages of high reliability, simple structure, short manufacturing process, and low cost, the automobile leaf spring has been widely used. The automobile leaf spring is generally a group of spring beams of approximately equal strengths formed by combining several sheets of alloy spring steels having various lengths.",
