An outer buffer spring 33 is fixedly connected between the lower end face of the buffer sleeve 20 and the bottom of the outer support cylinder 21, the outer buffer spring 33 is coaxially sleeved on the side wall of the outer support cylinder 21, an oil backflow space is reserved between the inner wall of the outer support cylinder 21 and the outer wall of the inner liquid storage cylinder 24, through backflow holes 25 which are distributed at equal angles are formed in the side walls of the upper part and the lower part of the inner liquid storage cylinder 24, corresponding electromagnets 23 are coaxially and fixedly installed in the inner walls of the upper end and the lower end of the inner liquid storage cylinder 24 respectively, and when the auxiliary permanent magnet ring 31 and the main permanent magnet 26 move in the inner liquid storage cylinder 24 to squeeze oil, the oil circulates between the inner liquid storage cylinder 24 and the outer support cylinder 21 through the backflow holes 25, so that hydraulic buffering is realized.
Working principle: when the magnetic levitation traction seat is used, referring to fig. 1-11, firstly, when a user enters a connecting column on an external carriage into a butt joint on a plate body 6, the connecting column on the carriage firstly extrudes and pushes a lock hook 10, at the moment, the lock hook 10 moves in the plate body 6 and stretches a return spring 12, one end of the lock hook 10 moves out of the plate body 6, the other end of the lock hook 10 is far away from a locking plate 13, at the moment, the locking plate 13 loses the limitation of the lock hook 10, after the lock hook 10 rotates to a set angle, the whole lock hook 10 is horizontally arranged, in the process, a tension spring 19 in a stretched state pulls the moving end of an auxiliary cylinder 34 through the reset action, so that the moving end of the auxiliary cylinder 34 can drive a sliding rod 18 to synchronously move, the sliding rod 18 drives a swing arm 15 to rotate through a first protruding shaft 16, at the moment, the swing arm 15 drives the locking plate 13 to move through the first protruding shaft 16, so that the locking plate 13 moves out of the plate 6, and the side of the locking plate 10 which is horizontally arranged, thus realizing quick connection of the carriage, when the carriage needs to be started, the sliding rod 18 can be pulled directly or the sliding rod 18 can be pulled through the sliding rod 18 when the locking is needed;
When the carriage applies impact force to the plate body 6, the plate body 6 can drive the guide rail 7 to adaptively slide on the rotating frame 2, in the process, the spring buffer 8 at the top end of the plate body 6 can buffer while rotating, buffer oil is stored in the inner sides of the inner liquid storage cylinder 24 and the outer support cylinder 21, the main permanent magnet 26 and the auxiliary permanent magnet ring 31 are positioned between the two electromagnets 23 to form a magnetic suspension structure, in the process, the support seat 1 can further apply the impact force to the buffer sleeve 20, the outer buffer spring 33 at the bottom of the buffer sleeve 20 can buffer, on the other hand, the buffer sleeve 20 can drive the main permanent magnet 26 at the bottom to move through the guide rod 22, so that the main permanent magnet 26 can move in the corresponding ring frame 28, because the three concentric ring frames 28 gradually increase in height, when the main permanent magnet 26 moves in the innermost ring frame 28, the thrust sleeve 27 on the main permanent magnet 26 is utilized to apply pressure to the arc plate 2908 on the innermost ring frame 28, so that the arc plate 2908 can drive the lifting rod 2907 to move, the lifting rod 2907 moves upwards, in the process, the lifting rod 2907 pulls the corresponding control frame 2906 to synchronously move, the chute on the control frame 2906 drives the stress block 2905 to move, at the moment, the stress block 2905 drives the moving plate 2901 to synchronously move, the moving plate 2901 compresses the pressure spring 2903 further, the locking head 2904 at the end part of the moving plate 2901 is separated from the corresponding positioning ring groove 30, at the moment, the main permanent magnet 26 is just matched with the auxiliary permanent magnet ring 31 on the innermost ring frame 28, each ring frame 28 is provided with the thrust sleeve 27, the matching process of the subsequent auxiliary permanent magnet ring 31 is carried out according to the steps, the sequential matching of the main permanent magnet 26 and the auxiliary permanent magnet rings 31 realizes gradient change of magnetic force in a larger range, therefore, the buffering effect is improved, when the thrust sleeve 27 is far away from the arc plate 2908, the pressure spring 2903 can apply pressure to the moving plate 2901 through the reset effect, so that the follow-up locking head 2904 reenters the corresponding positioning ring groove 30, and meanwhile, when the area of the main permanent magnet 26 and the area of the plurality of auxiliary permanent magnet rings 31 are changed, the main permanent magnet 26 and the corresponding auxiliary permanent magnet rings 31 can jointly push the oil in the inner liquid storage barrel 24 to flow, and the oil in the inner liquid storage barrel 24 can circulate through the backflow hole 25 and the outer supporting cylinder 21, so that the effect of further buffering the oil is achieved.
In the description of the present invention, unless otherwise indicated, the meaning of "a plurality" is two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front," "rear," "head," "tail," and the like are used as an orientation or positional relationship based on that shown in the drawings, merely to facilitate description of the invention and to simplify the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore should not be construed as limiting the invention. Furthermore, the terms "first," "second," "third," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
In the description of the present invention, it should be noted that, unless explicitly specified and limited otherwise, the terms "connected," "connected," and "connected" are to be construed broadly, and may be either fixedly connected, detachably connected, or integrally connected, for example; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium. The specific meaning of the above terms in the present invention will be understood in specific cases by those of ordinary skill in the art.
Although the present invention has been described with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described, or equivalents may be substituted for elements thereof, and any modifications, equivalents, improvements and changes may be made without departing from the spirit and principles of the present invention.
