Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

The utility model provides a prevent electronic wheelchair car of turning on one's side, as fig. 1 and fig. 2, including wheelchair body 1 and set up the first recess 11 on the relative both sides outer wall of wheelchair body 1, it is connected with pivot 12 to rotate on the relative cell wall of first recess 11, be equipped with commentaries on classics board 121 on the pivot 12, second recess 13 has been seted up on the wheelchair body 1 outer wall, be equipped with motor 131 in the second recess 13, the axis of rotation of motor 131 penetrate in the first recess 11 and with pivot 12 fixed connection, be equipped with the control of control motor 131 work on the wheelchair body 1.

As shown in fig. 1 and 2, when the wheelchair body 1 inclines laterally, the control element controls the motor 131 to work so as to rotate the rotating plate 121 out of the first groove 11, so that the rotating plate 121 is abutted against the ground, thereby limiting the side turning of the wheelchair body 1, reducing the side turning of the electric wheelchair and improving the safety of a rider.

As shown in fig. 1 and fig. 2, the control element includes a third groove 14 opened on the wheelchair body 1 and located below the first groove 11, the third groove 14 is distributed along the vertical direction, a draw rope 141 is arranged on the upper end groove wall, the draw rope 141 is distributed along the length direction of the third groove 14, a gravity ball 142 is arranged at the end of the draw rope 141 far away from the end connected with the groove wall of the third groove 14, a fourth groove 143 communicated with the third groove 14 is arranged below the outer wall of the wheelchair body 1, when the draw rope 141 is in the vertical state, the gravity ball 142 is located in the fourth groove 143, an infrared emitter 144 and an infrared receiver 145 for controlling the motor 131 to work are respectively arranged on the opposite groove walls of the fourth groove 143, at this time, the gravity ball 142 blocks the infrared receiver 145 from receiving the signal sent by the infrared emitter 144, so that the motor 131 does not work, when the wheelchair body 1 is tilted laterally, due, gravity ball 142 is under the pulling force effect of stay cord 141 for gravity ball 142 on the side wheelchair body 1 that the side direction was emptyd shifts out from in the fourth recess 143, and then the infrared receiver 145 of being convenient for receives the signal that infrared emitter 144 sent, and then control motor 131 begins work, and motor 131 drives pivot 12 and rotates this moment, and then drives and change board 121 and roll out first recess 11, is convenient for change board 121 and supports wheelchair body 1, reduces empting of wheelchair body 1.

As shown in fig. 1 and 2, the air bag 15 is disposed at one end of the rotating plate 121 far from the rotating shaft 12, and the arrangement of the air bag 15 reduces the impact force generated when the rotating plate 121 contacts with the ground, so as to stabilize the rider on the wheelchair body 1. When the rotating plate 121 is positioned in the first groove 11, the outer wall of the air bag 15 extends out of the outer wall of the wheelchair body 1, so that the impact force generated on the wheelchair body 1 when a foreign object collides with the outer wall of the wheelchair body 1 can be reduced conveniently. Further, the outer wall of the air bag 15 is provided with a plurality of rubber strips 151, and each rubber strip 151 is distributed along the length direction of the air bag 15. At this time, the arrangement of the rubber strips 151 relieves the impact force generated by the impact of the foreign object on the air bag 15, protects the air bag 15, and enhances the strength of the air bag 15 due to the arrangement of the plurality of rubber strips 151. In addition, the outer wall of one side of the rotating plate 121 departing from the bottom of the first groove 11 is provided with a plurality of elastic anti-collision strips 17, and the impact force of foreign objects on the wheelchair body 1 is further reduced due to the arrangement of the anti-collision strips 17.

As shown in fig. 3, the inner wall of the upper end of the air bag 15 is provided with a plurality of elastic rubber columns 16 distributed along the height direction of the air bag 15. That is, when the air bag 15 is damaged, the rubber column 16 still keeps the air bag 15 at the certain height and relieves the impact force of the ground to the rotating plate 121.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
