Example 1

Referring to fig. 1, the invention provides an intelligent remote control type positioning triangular warning device for the internet of things, which comprises a base trolley 1, wherein a triangular warning board 2 is rotatably connected to the upper surface of the base trolley 1, the triangular warning board 2 is driven to rotate by a driving assembly, and the base trolley 1 is further provided with a control assembly 3 for controlling the state of the triangular warning board 2, a posture detection module 4 for detecting a first gesture induction of the state of the base trolley 1 and a GPS positioning module 5 for positioning the position of the base trolley 1.

When the remote control type base trolley is used, the base trolley 1 is a remote control type trolley and can move automatically. The triangular warning board 2 on the base trolley 1 has two states of being parallel and vertical to the surface of the base trolley 1. When traffic accidents happen and the triangular warning device needs to be used for warning, the control component 3 controls the driving component, the driving component drives the triangular warning board 2 to stick up to be perpendicular to the surface of the base trolley 1, the base trolley 1 is driven to move to a warning position through the control component 3, secondary accidents which possibly happen when the triangular warning board 2 is placed in the direction of the coming vehicle by workers are avoided, and the safety of the triangular warning board 2 in the placing process is improved.

In this embodiment, the triangular warning device further includes a power supply voltage display module 6 for displaying the power supply voltage of the base trolley 1, and the module is initialized by the IIC and displays the voltage value.

In this embodiment, the triangular warning board 2 is a passive reflector made of a plastic reflective material, and when a driver encounters an emergency fault and stops for maintenance or an accident on the road, the reflective performance of the triangular warning board 2 can remind other vehicles to avoid the accident, so that a secondary accident is avoided.

As a further description of the above embodiment, the triangular warning board 2 is rotatably connected to the upper surface of the base carriage 1 by a torsion spring 7.

When this embodiment uses, triangle warning sign 2 rotatable coupling is on base dolly 1's top surface, and its concrete connection mode is that the bottom of triangle warning sign 2 is equipped with balanced hinge structure with the junction at base dolly 1 top, and balanced hinge structure concrete expression is for utilizing torsion spring 7 to accomplish the rotation of triangle warning sign 2. The torsion spring 7 is a mechanical force storage structure, stores force by twisting or rotating an elastic material, and releases the force by utilizing the lever principle, so that the launcher has certain mechanical energy. One end of the torsion spring 7 is fixed to the top of the base trolley 1, the other end of the torsion spring is connected with the triangular warning board 2 in a vertical state, the triangular warning board 2 can rotate around the center of the torsion spring 7, and the torsion spring 7 generates elastic deformation output torque through torsion. Once the triangular warning board 2 starts to rotate, the torsion spring 7 generates a resistance force for pulling it back to the fixed position, i.e., the vertical position, converted from a rotational force.

As a further description of the above embodiment, the driving assembly includes an inverted "heart-shaped" rail 8, a slider 9 capable of moving along the "heart-shaped" rail 8 is arranged in the "heart-shaped" rail 8, the upper end of the slider 9 is connected with the end of the suspended end of the triangular warning board 2 through a connecting shaft 10, a spring 12 is connected to the bottom of the "heart-shaped" rail 8, the other end of the spring 12 is fixed to the bottom of the base trolley 1, the driving assembly further includes a motor 11, and the output shaft of the motor 11 is hinged to the slider 9. The track formed from the heart-shaped tip to the heart-shaped recess in the heart-shaped track 8 is a downward pushing track 13, the track formed from the heart-shaped recess to the heart-shaped tip is an upward sliding track 14, the depth of the heart-shaped track 8 is gradually reduced from the downward pushing track 13 to the heart-shaped recess, and then gradually increased from the heart-shaped recess to the upward sliding track 14.

When the intelligent warning board is used in the embodiment, the inverted heart-shaped track 8 is perpendicular to the horizontal plane of the base trolley 1, the slide block 9 capable of moving along the track is arranged inside the track, the slide block 9 is connected with the top end of the triangular warning board 2 through the connecting shaft 10, and two ends of the connecting shaft 10 are respectively hinged with the slide block 9 and the triangular warning board 2. The slider 9 moves around the heart-shaped track 8 for one circle to form a movement period, the track formed from the heart-shaped tip to the heart-shaped top end recess is a downward pushing track 13, and the other half of the track formed from the heart-shaped top end recess to the heart-shaped tip is an upward sliding track 14. The depth of the heart-shaped track 8 is inconsistent and is stepped, the depth of the heart-shaped track 8 is reduced from the downward pushing track 13 to the concave part at the top end of the heart-shaped track, and then the concave part at the top end of the heart-shaped track is increased to the upward sliding track 14, so that the unidirectional irreversibility of the sliding block 9 in the moving direction is ensured. Meanwhile, the upper slide rail 14 is slightly lower than the lower slide rail 13, so that a clamping groove 15 is formed at the concave part of the top end of the heart-shaped part.

The arrangement of the spring 12 at the bottom of the heart-shaped track 8 can play a role of boosting and buffering. Specifically, one end of the spring 12 is fixed on the inner surface of the bottom of the base trolley 1, and the other end is connected with one side of the concave position of the top end of the inverted heart-shaped rail 8. When the triangular warning board 2 is manually pressed down, the sliding block 9 moves towards the clamping groove 15 from the pushing track 13, the spring 12 is gradually compressed along with the movement of the sliding block 9, the sliding block is released after the sliding block is compressed to the maximum degree, external force disappears, the sliding block 9 moves to the clamping groove 15 under the assistance of the spring 12, and therefore the triangular warning board is fixed in a horizontal state. Similarly, when the slide block 9 is driven by the output shaft of the motor 11 and moves to the upper slide rail 14 through the clamping groove 15, the spring 12 is gradually compressed along with the movement of the slide block 9, after a certain time, the motor 11 stops working, and the slide block 9 moves to the tip of the heart-shaped rail 8 from the upper slide rail 14 under the assistance of the spring 12, so that the triangular plate can be converted into a vertical working state.

Wherein, motor 11 is fixed in base dolly 1 inside, and its output shaft is connected with slider 9, and when motor 11 was triggered work, the output shaft rotated and has given force, drives slider 9 and goes up slide rail 14 motion by draw-in groove 15, and motor 11 stops work after the removal time.

In summary, the triangle warning device includes two types of locking states and working states, and the conversion process of the locking states and the working states is as follows:

when the triangular warning board 2 is idle, the sliding block 9 is fixed at the clamping groove 15 of the heart-shaped track 8 and is in a locking state, namely the triangular warning board 2 is parallel to the base trolley 1. When the triangular warning board 2 is in a working state, the triangular warning board 2 can rotate along with the sliding of the sliding block 9 along the heart-shaped track 8 until the triangular warning board rotates to be in a vertical state. If the triangular warning board 2 works, the Bluetooth control module drives the motor 11 to work, the sliding block 9 is driven to leave the clamping groove 15 by utilizing the rotation of the output shaft of the motor 11, the spring 12 below the heart-shaped track 8 is gradually compressed in the process, after the motor 11 stops working for a certain time, the sliding block 9 can move to the tip of the heart-shaped track under the assistance of the spring 12 below the track, and meanwhile, the triangular warning board 2 is bounced to a vertical state by virtue of the restoring force of the torsion spring 7 at the balance hinge; if the working state is finished, the warning triangle can be manually pressed, the spring 12 below the track can be compressed by the downward pushing force of the sliding block 9, the sliding block 9 moves towards the clamping groove 15 until being locked by the aid of the elastic force of the spring 12 below the sliding block after hands are released, and meanwhile the torsion spring 127 at the balance hinge stores force again to fix the warning triangle in the next working state.
