Description of the new type: [Technical field to which the new type belongs] This new type is about an electric wheelchair, more specifically-a type of electric that can be used to lie back and lift your feet at the same time to achieve :::: a pull injury Wheelchair reclining device. Child with [prior art] •: Most of them are physically ill with a physical disability or serious injury. Sitting in a wheelchair sometimes requires stretching of bones and muscles, or from a sickbed, so wheelchairs usually use The function of the motor :: tilt: When the human body is sitting in a wheelchair, the back is usually placed against r. Due to the turning point of the chair back and the pro-articular joint θ§ of the human body, in order to solve this problem, the operator Describes a movable back design. Μ Referring to FIG. I, it is known that there is an electric wheelchair 10 mainly on a frame U = Yes—a seat mechanism 12 and a backrest mechanism 13 'the seat mechanism 12 is also on—the seat 121 is available for users to ride The back lying mechanism 13 has a frame main frame 131 which can be reclined on the frame U and can be reclined on the main frame 13 1 which can be reclined linearly and displaceably. The pneumatic pressure cylinder 133 above the back cushion is connected to the seat back main frame i3i below the wheel assembly 134 and the linear actuator provided on the frame η to support the seat back main frame ⑶. 135, the lower end of the seat back main frame ⑶ is pivotally connected to the frame u extension wing m to form a pivot point 1; one end of the pneumatic cylinder ⑴ is connected to the backrest 塾 132, and the other end is connected to the chair The lower end of the back main pole 131 provides a backrest 塾 132 with upward lifting force. The sheave assembly M263930 134 has a guide wheel plate η " fixed on the lower end of the seat back main frame 131, and two shafts are provided on the guide wheel plate. The guide wheels 1342 at both ends of 1341, a fixing plate 1343 fixed to the frame η, and a rope wound around the two guide wheels 1342 ^ ⑽ One end of the rope 1344 is fixed to the fixed On the fixed plate 1343, the other end is fixed to the lower part of the backrest 塾 U2. When the linear actuation II U5 moves the entire reclining mechanism 13 to lie down (as shown in FIG. 2), the guide wheel plate 1341 rotates. 'The guide wheel ⑽ can stretch the rope ⑽, ^ 1344, that is, the traction drives the back cushion 132 to move closer to ㈣i2i'. When the human body lies on the back cushion 132 to lie flat, the backrest 塾132 The movable design can adapt to the position of the back of the human body, so that the human body can be pulled. 'The above-mentioned electric wheelchair U) mechanism can indeed reduce the pull injury to the back of the human body. However, there are still problems to be solved in its use. As the human back moves into the two thousand = action, the joints will naturally stretch the muscles of the feet and naturally cover them. The feet, "," and the Zhizhi Electric Wheelchair 10 does not provide a foot lift mechanism to the feet, telling the user that when doing a reclining movement, often causing discomfort in the feet. 1 () If you want to attack the foot-lifting mechanism, it is necessary to ==: linear actuator as a drive, this will not only add an additional 'knowledge electric wheelchair 1. by rope ...:; magic 33: Force 2: To move, the rope 1344 must first overcome the pneumatic pressure of 6, 4 forces before the material & ㈣f㈣132 material, so when the backrest cushion 132 is lying down, the material capacity is "human money pulling love." 6 M263930 [New content] Therefore, the purpose of this new model is to provide a back-to-back reclining and foot-lifting action at the same time, which will not have a pulling effect on the back and feet of the human body.

The upper end of the disc backrest link 71 is connected to the lower end, and the lower end is provided on the rear pivot ear 35 of the seat unit 30. The rod 73 is connected to the lower end of the straight rod below the seat 31 and the lower end of the toggle link 72, and the front end of the rod 73 is pivotally connected to the footrest main frame 5m. ^ ^ The above is an overview of the shape of the various components of the new electric wheelchair reclining device '. Then, the reclining action of the new type and what can be expected to be achieved are described below: Xi Chen Refer to Figure 8 and Figure 9, and use If the user wants to perform a reclining action, firstly actuate the controller 454 to start the driving unit 60, so that the main force 41 of the chair can be tilted to the predetermined angle with the turning point u of the second shaft connection plate 42 as the center. '. When the seat back main frame 41 performs a reclining action, the first rope 48 can release the restraint on the moving frame 43 because of the change in the position of the whole block 47. The moving frame due to the elasticity of the A elastic element 46 and its own weight Impact, you can immediately drive the Beibei II 11 M263930 pad 44 down, so that it can adapt to the back of the human body without generating pulling shear. In addition, while the seat back main frame 41 is lying down, the position of each lever of the linkage unit 70 will change, and the toggle link 72 will swing to move the driving rod 73 backward, so that the foot pad main frame 51 can The ear 512 swings upwards at the turning point, which allows the user to perform a leg-raising action, and because of the change in position, the second rope 56 can release the restraint on the slider 52, which is pushed by the pneumatic element 55 The extension movement can drive the leg cushion 53 and the foot cushion 54 to slide to the lower end, so that it can adapt to the extended state of the human calf and the sole of the foot without generating a shear force. Referring to FIG. 10 and FIG. 11, the seat back main frame 41 can be tilted to a horizontal state so as to allow the user's back to lie flat. At this time, the foot pad main frame 51 also reaches the top position at the same time, so that the leg cushion 53 It is exactly flush with the seat cushion 32, and the human body can be straightened at this time, so that the user's head, body, and feet can be completely flat.桊 The new electric wheelchair reclining device, described above ------- Women_ You have made improvements to the lack of use of electric wheelchairs 10. The technology used in this new model is included in Unit 4G and Unit 50. Yes-Linkage unit 70z links single pi 70 corpses, and with a single drive unit, it can be operated at the same time = unit 40 and heel unit 50, allowing the user to reach back lying and lift his feet. The structure 'achieves the goal of saving costs, and M's new backrest 塾 44 can slide according to the position of the back of the human body, and the legrest 塾 and foot cushion 54 can also be moved according to the extension of the human calf and feet. In the action book: Pulling situation, it is quite convenient and comfortable to use, plus two ropes! Wrongly, the first rope 48 suspends and supports the moving frame 43 and the sixth pair of sliding frames 52 hangs and cuts. This type of support structure allows the back 12 M263930 44 and the leg pad 53 to react immediately. It will cause dullness, and it can get the best sliding effect. The above mentioned is only one of the preferred embodiments of the present invention. If it is not used to limit the scope of the implementation of the present invention, that is to say, the simple ones made according to the scope of the new application and the contents of the new application 5 Effect changes and modifications are still covered by the new patent.
