According to present pre-ferred embodiments, multiple Athey wheels 16 of described homonymy are linked together by balancing stand 17, for held stationary with operate continuously.Described first feed screw nut pair 212 is driven by lead screw motor, for realizing the function that can keep relative equilibrium when multifunctional free chair is climbed up and down; Second feed screw nut pair 213 is driven by lead screw motor, for realizing the function of freedom chair lifting.
Described four-bar mechanism 211 comprises first connecting rod 2111, second connecting rod 2112, third connecting rod 2113 and double leval jib 2114, wherein said first connecting rod 2111 two ends are provided with hinges, one end and described second connecting rod 2112 active link, the other end and described third connecting rod 2113 active link, described double leval jib 2114 is provided with three hinges, its two ends respectively with the other end active link of described second connecting rod 2112 and described third connecting rod 2113, described double leval jib 2114 is crossed hinges with described first feed screw nut pair logical 212 and is connected, described first feed screw nut pair 212 other end is connected with described second connecting rod 2112 by hinge.
Further, described double leval jib 2114 is V-shaped structure, and described hinges is arranged at its three end points places.The described motor for driving Athey wheel 16 to move is arranged at described first connecting rod 2111.
According to present pre-ferred embodiments, described seat cushion 12 has seat cushion four-bar mechanism 14, it is made up of the first seat cushion link 141, second seat cushion link 142, the 3rd seat cushion link 143 and seat cushion 12, wherein said first seat cushion link 141 one end is by hinges and described base 21 active link, the other end and described seat cushion 12 active link, described second seat cushion link 142 two ends are respectively by hinges and described first seat cushion link 141 and the second seat cushion link 142 active link.
Further, described multifunctional free chair also comprises backrest 11 and handrail 131, and wherein said backrest 11 is fixedly installed in described 3rd seat cushion link 143, and described handrail 131 is fixedly installed on described backrest 11.Described handrail 131 is provided with retaining ring 132, and described retaining ring 132 one end activity is fixed on described handrail 131, and the other end is fixed by snap close, serves the effect of safeguard protection.When user needs to use, first by snap close, retaining ring 132 being opened, after user is occupied stably, then locking from being about to retaining ring 132.
Further, described handrail 131 is provided with the second feed screw nut pair press button, travels press button, upward slope press button and descending press button.When user is wanted to stand, can press the second feed screw nut pair 213 press button, motor drives feed screw nut's secondary motion, and user can be assisted to stand.After user is stood, can be hand steered retaining ring 132 or handrail 131, namely follow freedom chair at retaining ring 132 and handrail 131 to walk about the activity of grade around doing suitable turning round in scope.
Please refer to Fig. 4 and Fig. 5, Figure 4 shows that the multifunctional free chair climbing schematic diagram of present pre-ferred embodiments, Figure 5 shows that the multifunctional free chair descending schematic diagram of present pre-ferred embodiments.Press traveling press button, motor-driven caterpillar tracks wheel 16 rotates, and Athey wheel 16 drives crawler belt 15 to rotate, and can realize the road driving that lies low.When user needs climbing, press climbing press button, first feed screw nut pair 212 motor rotates forward, the first feed screw nut pair 212 is driven to extend, third connecting rod 2113 and double leval jib 2114 is made to swing an angle, thus make second connecting rod 2112 and crawler belt 15 upper surface fold a positive-angle, and base 21 remains relative level state, namely achieves the function of climbing.When slope will be climbed up, press descending press button, first feed screw nut pair 212 motor reversal, third connecting rod 2113 and double leval jib 2114 is made to swing an angle in the other direction, making freedom chair recover level gradually, when arriving level, pressing descending press button, i.e. the first feed screw nut pair 212 motor stalls, can enter the road that lies low and run.When needs descending, press descending press button, first feed screw nut pair 212 motor reversal, make third connecting rod 2113 and double leval jib 2114 backswing angle, thus make second connecting rod 2112 and crawler belt 15 upper surface fold a negative angle, and base also remains relative level state, namely realize descending function.When completing descending, pressing upward slope press button and can reset multifunctional free chair to original state.
Just current, traditional seat and motorized motions functions of seat single, for single user, this can not meet popular demand.The first breakthrough of this seat be exactly utilize double leval jib and feed screw nut pair principle design to go out a kind of seat can the freedom chair of aiding upright, mounting is by hinges and first connecting rod active link, user suitably can adjust the angle of seat according to self-condition, also user can be assisted to stand, to adapt to different user.The second largest breakthrough of this seat utilizes double leval jib and screw mandrel principle by shaft coupling and associated electric motor, and motor-driven caterpillar tracks wheel rotates, and Athey wheel drives crawler belt to rotate, and can realize the road driving that lies low.When climbing up slope, press descending press button, the first feed screw nut pair motor reversal, make third connecting rod and double leval jib swing an angle in the other direction, make freedom chair recover level gradually, be up to the standard state; When needs descending, press descending press button, feed screw nut pair motor reversal, make third connecting rod and double leval jib backswing angle, thus make second connecting rod and crawler belt upper surface fold a negative angle, and base also remains relative level state, namely realizes descending function; Safety device of the present invention have employed the design of snap close, when user needs to use, is first opened by retaining ring by snap close, after user is occupied stably, then from being about to retaining ring locking; When user is wanted to stand, can press the second feed screw nut pair press button, motor drives feed screw nut's secondary motion, and user can be assisted to stand.After user is stood, can be hand steered retaining ring or handrail, retaining ring and handrail around do in scope suitable turning round namely follow freedom chair to walk about etc. movable.Instant invention overcomes the deficiencies in the prior art, use procedure is simply comfortable, simple operation, safe and reliable, comfort level needed for user can carry out the angle regulating freedom chair, effectively can realize climb and fall function simultaneously, there is good practicality and very large potential generalization.
Although the present invention with preferred embodiment disclose as above, so itself and be not used to limit the present invention.Persond having ordinary knowledge in the technical field of the present invention, without departing from the spirit and scope of the present invention, when being used for a variety of modifications and variations.Therefore, protection scope of the present invention is when being as the criterion depending on those as defined in claim.
