It is based on the problem of the above-mentioned knowledge wheel ^ ^ ^. Wheelchair use, such as playing a research can produce a more The rational construction of the rationale M m In view of the fact that the inventor has made a breakthrough in the manufacturing and development of related products, the inventor has been in the process of designing and prudently evaluating the products. The invention is practicable. 5 200924730 [Invention] The main object of the present invention is to provide a double shock absorption with a wheelchair frame. The problem is to solve the problem of how to develop a ladder force. The innovative wheelchair frame with ideal practicability is considered as a breakthrough; the front and rear wheels of the wheelchair frame are respectively provided with front and rear wheels, and the two sides of the middle section of the wheelchair frame are provided with driving wheels. The rear wheel set is set at the swing end of the swing bracket provided at the rear end of the wheelchair frame, and the top of the wheelchair frame is provided with a seat bracket portion; © "The technical feature of solving the problem is mainly in the swing bracket. A double-coefficient shock absorber is arranged between the wheelchair frame and the wheelchair frame, and the elastic member of the front section is arranged on the wheelchair frame, and the elastic end of the elastic member is fixed. rear end a sliding seat is coupled to the front end of the rear elastic member, the sliding seat is slidable forward and backward on the wheelchair frame, and the rear end of the elastic member is connected at an oblique downward angle to the swinging end of the swing bracket; The unique design enables the present invention to substantially achieve the following advantages over the prior art: 〇#When the wheelchair frame is tied to a flat road, the vibration of the rear wheel set and the swing bracket is compensated by the double coefficient The elastic member of the rear part of the device generates a shock absorbing cushioning effect, and the current wheel set performs the stepping (or stepping) action to cause the wheelchair frame to tilt and raise the angle of the swinging bracket to a larger angle, which further presses the double coefficient damper The elastic part of the elastic part of the front part of the device is elastically fed, so that the swinging branch can be raised to a larger angle, thereby changing the center of gravity of the wheelchair body, assisting the wheelchair frame and the front wheel to lift, effectively improving the pedaling force, improving the effectiveness and quality of the wheelchair. Practical and progressive. 6 200924730 [Embodiment] Please refer to Figures 1, 2 and 3, which are preferred embodiments of the double shock absorbing structure of the wheelchair frame of the present invention, but the embodiments are for illustrative purposes only, and The front wheel set 10 and the rear wheel set 20 are respectively disposed before and at the rear end of the wheelchair frame 〇5, and the drive wheel 30 is disposed on the middle side of the wheelchair frame 〇5, wherein The rear wheel set 20 is assembled on the swing end 41 of the swing bracket 40 provided at the rear end of the wheelchair frame 05, and the top of the wheelchair frame 5 is provided with a seat bracket portion 50 for the wheelchair seat. The core design of the invention is mainly: the double-coefficient damper 60 is arranged between the swing bracket 40 and the wheelchair frame ' 5, and the double-coefficient damper 60 includes a difference in elastic modulus. The front elastic member 61 and the rear elastic member 62 have different elastic coefficients than the rear elastic member 62, and the front and rear elastic members 61 and 62 have a spring. Or the oil shock absorber or the elastic rubber as a whole, and the front elastic The member 61 is placed on the wheel frame 〇5, and the front end 63 of the front elastic member 61 is fixed to a positioning seat portion 06 provided by the wheel==®, and the rear end portion of the front elastic member 61 is supported by a sliding seat 70. The front end elastic member 62 is coupled to the front end, and the sliding seat 7 is slidable on the wheelchair frame 05 for the front-rear direction. The rear end portion 64 of the rear elastic member rib has an oblique downward angle; the swing end of the k-swing bracket 40 41 connected. Wherein, the sliding seat 70 can be a U-shaped seat type, and the sliding seat 70 corresponds to the side of the wheelchair frame 〇5. 1 np / 1 J has an orifice 71, the wheelchair frame 〇 5 The sliding seat 70 is provided with an elongated guide groove 〇 υ υ υ υ υ υ υ υ 滑动 滑动 滑动 滑动 滑动 滑动 滑动 滑动 滑动 滑动 υ 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔 穿孔After the elongated guide groove 06, the spacer 73 is positioned by the spacer 73, the microphone 11 mesh 74. 7 200924730 H The rear elastic member 62 is connected to the sliding seat 70 by (4) 65, and the rear end elastic member 62 is configured to be swingable. The design of the structure is as follows. The state of use of the present invention is as follows: As shown in Figures 5 and 6, the present invention mainly provides the structural design of the double-coefficient damper 60 by the wheelchair frame 〇5. When the rear wheel set 2 of the wheelchair is driven to cause the swinging end 41 of the swing bracket 40 to rise © due to crossing the road surface projection, the elastic member 62 of the rear portion of the double-coefficient damper 60 is elastically collapsed ( The shock absorber buffer effect is achieved as indicated by the arrow L1 of the sixth line. As shown in Figs. 7 and 8, when the front wheel group 1 is lifted by the ladder during driving, and the front end of the wheelchair frame 5 is tilted upward, the rear end of the wheelchair frame 05 and the swing bracket 4 are swung. The narrowing of the angle formed between the ends 41 will cause the elastic member 62 of the second stage of the double-coefficient damper 60 to further push the sliding seat 70 to cause the front elastic member 61 to collapse (for example, the arrow L2 of Fig. 8). As shown in the figure, by the front elastic member 61, the characteristic β of the collapse can be generated, so that the amplitude of the front end of the wheelchair frame 〇5 is inclined upward (that is, the amplitude of the front wheel group 1〇 is further increased), and the center of gravity of the wheelchair body is shifted. The state of changing (but not falling backwards) (as indicated by arrow L3 in Fig. 7), thereby achieving the effect of assisting the ladder. The invention has the advantages that: the double-coefficient damping is set up between the swing bracket and the wheelchair frame, and the innovative unique design is used.
