The control box will first drive the electric push rod to start pulling the connecting block inward. The connecting block will push the lifting frame to rotate clockwise by 90 degrees through the support rod, so that the power-assisted wheel contacts the ground. Then the control box drives the motor to drive the first gear to rotate. The first gear drives the second gear to rotate through the transmission belt.

If the plumb bob drives the axis of the angle sensor to reset and remains for a few seconds, the control box will stop the motor and will retract the lifting frame through the electric push rod.

When going uphill, the plumb bob will drive the axis of the angle sensor to rotate in the opposite direction of the movement direction under the influence of gravity. The control box will increase the operating power of the motor to improve the climbing ability. When going downhill, the plumb bob will drive the axis of the angle sensor to rotate in the same direction as the movement direction under the influence of gravity. The control box will drive the motor to reverse to reduce the downhill speed of the base. By driving the axis of the angle sensor to rotate through the plumb bob to obtain road surface information, and then driving the assist wheel to rotate through the motor for assistance, the effect of not having to pull with effort when going uphill and downhill is achieved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] In an embodiment of the present application, by providing a portable electronic information communication device, the technical problem that the above-mentioned communication device is moved by universal wheels under the bottom plate and is laborious when encountering uphill and downhill due to the heavy equipment is effectively solved. When pulling the pull rod forward to move the base forward, due to inertia, the plumb bob inside the base will remain stationary, while the angle sensor moves forward with the base. Therefore, the plumb bob will relatively rotate around the axis of the angle sensor. The angle sensor senses the rotation of the plumb bob and will send an electrical signal to the control box. The control box will first drive the electric push rod to start pulling the connecting block inward. The connecting block will push the lifting frame to rotate clockwise by 90 degrees through the support rod, so that the assisting wheel contacts the ground. Then the control box drives the motor to drive the first gear to rotate. The first gear drives the second gear to rotate through the transmission belt. The second gear will drive the assisting wheel to rotate. The assisting wheel will drive the base to move through the friction with the ground. If the plumb bob drives the axis of the angle sensor to reset and remains for a few seconds, the control box will stop the motor and will retract the lifting frame through the electric push rod. By driving the axis of the angle sensor to rotate through the plumb bob to obtain the motion state, the control box can intelligently drive the motor, achieving the effect of assisting when pulling and stopping assisting. A photovoltaic panel is fixedly installed at the top of the box body, which can increase the battery life. When encountering an uphill, the plumb bob will drive the axis of the angle sensor to generate a rotation angle opposite to the moving direction due to the influence of gravity. The control box will increase the operating power of the motor to improve the climbing ability. If going downhill, the plumb bob will drive the axis of the angle sensor to generate a rotation angle in the same direction as the moving direction due to the influence of gravity. The control box will drive the motor to reverse to reduce the downhill speed of the base. By driving the axis of the angle sensor to rotate through the plumb bob to obtain road surface information and then driving the assisting wheel to rotate through the motor for assistance, the effect of not having to pull laboriously when going uphill and downhill is achieved.

[0023] Embodiment

[0024] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown in [relevant figures], the technical solution in the embodiment of the present application effectively solves the above-mentioned technical problem that the communication device is moved by universal wheels under the bottom plate and is laborious when encountering uphill and downhill due to the heavy equipment. The general idea is as follows:

[0025] In view of the problems existing in the prior art, the present utility model provides a portable electronic information communication device, including a base 1. A lifting frame 2 is rotatably installed at the bottom end of the base 1. A motor 3 is fixedly installed inside the lifting frame 2. A first gear 4 is fixedly installed at the side end of the motor 3. An assisting wheel 5 is rotatably installed at the bottom end of the lifting frame 2. A second gear 6 is fixedly installed at the side end of the assisting wheel 5. A transmission belt 7 is installed at the side end of the lifting frame 2. An angle sensor 11 is fixedly installed inside the base 1. A plumb bob 16 is fixedly installed at the side end of the angle sensor 11.

[0026] Both ends of the transmission belt 7 are respectively connected to the first gear 4 and the second gear 6. Inside the base 1, a control box 21 is fixedly installed, a storage battery 22 is fixedly installed, and an electric push rod 12 is fixedly installed; the control box 21 and the electric push rod 12 are connected by wires, and the control box 21 is connected to the motor 3 and the angle sensor 11 by wires.

[0027] A support rod 8 is rotatably installed at the side end of the lifting frame 2, and a connecting block 9 is rotatably installed at the top end of the support rod 8; the connecting block 9 is fixedly connected to the electric push rod 12. At the top end of the base 1, a box body 14 is fixedly installed. Inside the box body 14, a communication device body 18 is fixedly installed. At the top end of the box body 14, a photovoltaic panel 17 is fixedly installed. At the side end of the box body 14, a box door 15 is fixedly installed. Universal wheels 13 are fixedly installed at the four corners of the base 1, and a pull rod 19 is fixedly installed at the top end of the base 1.

[0028] Working principle:

[0029] First step, when in use, multiple communication device bodies 18 can be placed inside the box body 14. The control box 21 is internally installed with an STM32 microcontroller, which can drive the motor 3 and the electric push rod 12 according to the electrical signals sent by the angle sensor 11, pull the pull rod 19 forward to make the base 1 move forward. Due to inertia, the plumb bob 16 inside the base 1 will remain stationary, while the angle sensor 11 moves forward with the base 1. Therefore, the plumb bob 16 will relatively rotate around the axis of the angle sensor 11. The angle sensor 11 senses the rotation of the plumb bob 16 and will send an electrical signal to the control box 21. The control box 21 will first drive the electric push rod 12 to start pulling the connecting block 9 inward. The connecting block 9 will push the lifting frame 2 to rotate clockwise by ninety degrees through the support rod 8, so that the assisting wheel 5 contacts the ground. Then the control box 21 drives the motor 3 to drive the first gear 4 to rotate. The first gear 4 drives the second gear 6 to rotate through the transmission belt 7. The second gear 6 will drive the assisting wheel 5 to rotate. The assisting wheel 5 will drive the base 1 to move through the friction with the ground. If the plumb bob 16 drives the axis of the angle sensor 11 to reset and remains stationary for a few seconds, the control box 21 will stop the motor 3 and will retract the lifting frame 2 through the electric push rod 12. By driving the axis of the angle sensor 11 to rotate through the plumb bob 16 to obtain the motion state, the control box 21 can intelligently drive the motor 3, achieving the effect of pulling for assistance and stopping without assistance.

[0030] In the second step, a photovoltaic panel 17 is fixedly installed at the top of the box body 14, which can increase the endurance of the battery 22. When going uphill, the plumb bob 16 will drive the axis of the angle sensor 11 to generate a rotation angle opposite to the moving direction under the influence of gravity. The control box 21 will increase the operating power of the motor 3 to improve the climbing ability. If going downhill, the plumb bob 16 will drive the axis of the angle sensor 11 to generate a rotation angle in the same direction as the moving direction under the influence of gravity. The control box 21 will drive the motor 3 to reverse to reduce the downhill speed of the base 1. The road surface information is obtained by driving the axis of the angle sensor 11 to rotate through the plumb bob 16, and then the motor 3 is used to drive the auxiliary wheel 5 to rotate for assistance, achieving the effect that there is no need to pull with effort when going uphill and downhill.

[0031] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or variations can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. And the obvious changes or variations derived therefrom are still within the protection scope of the present invention.
