DETAILED DESCRIPTION

[0028] The utility model will be further explained in detail in combination with the drawings and specific embodiments.

[0029] Example 1

[0030] As shown in Figure 1 and 2 , the embodiment provides a remote control road warning device, which comprises a remote control car 1, a remote controller 2 and a warning board 3, wherein a hinge 4 is arranged between the bottom surface of the warning board 3 and the top surface front part of the remote control car 1, the hinge 4 is spaced apart and provided with two, the hinge 4 can be connected with the warning board 3 and the remote control car 1 through screws, and the opening and closing mouth of the hinge 4 faces the front side of the remote control car. In this way, the maximum limit of the forward rotation of the warning board 3 is perpendicular to the top surface of the remote control car 1, and the maximum limit of the backward rotation of the warning board 3 can be attached to the top surface of the remote control car 1. In addition, a storage groove is arranged at the back of the warning board 3, a support frame 5 is rotatably connected to the upper part in the storage groove, in this way, when the support frame 5 is turned out to the maximum limit, it will be in contact with the upper inner side wall of the storage groove, maintaining an angle of about 90° between the support frame 5 and the warning board. Therefore, when the support frame 5 is turned out of the storage groove and supported on the top surface of the remote control car 1, the warning board 3 is in an inclined state, and the warning surface thereof is inclined upward.

[0031] In summary, the use principle of the warning device is as follows: when being stored, first, the support frame 5 is turned into the storage groove at the back of the warning board, then the whole warning board 3 is turned backward until it is attached to the top surface of the remote control car, as shown in Figure 2As shown, the remote control car 1 and the warning sign 3 can occupy a smaller space in the car. When in use, the warning sign 3 is first rotated forward to the maximum extent to facilitate pulling out the support frame 5 in the storage slot, then the support frame 5 is pulled out to the maximum extent, and finally the warning sign 3 is rotated backward until the support frame 5 contacts the top surface of the remote control car 1. Figure 1 As shown in the figure, the warning sign 3 and support frame 5 are both tilted. Under the weight of the warning sign, the support frame 5 can effectively maintain its support position. Furthermore, because the remote-controlled car 1 and warning sign 3 are positioned relatively low, while the eyesight of the driver of the vehicle coming from behind is relatively high, the warning sign is tilted upward when in use, making it easier for the driver of the vehicle coming from behind to notice and ensuring a more effective warning.

[0032] In addition, this warning device uses a conventional 2.4GHz radio remote control to control the driving of the remote control car, so it will not be described in detail here.

[0033] like Figure 3 and 4 As shown, considering the warning effect at night and in rainy weather conditions where visibility is easily obstructed, a warning light 31 is provided in the middle of the front side of the warning sign, and a reflector 32 is provided around the warning light 31. The warning light 31 is powered by a battery box 6 located on the back of the warning sign 3, and a corresponding power switch 7 is also located on the back of the warning sign. When in use, the power switch 7 is turned on as needed, and then the remote control car is controlled to drive to the target location. At the same time, in the above-mentioned weather conditions where visibility is easily obstructed, since the remote control operator faces away from the warning light 31 and the warning sign 3 generally needs to be placed 50 meters behind the car, a remote control indicator light 33 is provided on the upper end of the back of the warning sign 3 to facilitate the remote control operator to accurately grasp the position of the remote control car and ensure the accuracy of the remote control operation.

[0034] like Figure 4As shown, the support frame 5 is simple in structure, including two support arms 51 and a crossbar 52 connecting the lower ends of the two support arms 51, and the two support arms 51 are rotatably connected with the receiving groove, and the receiving groove has a shape adapted to the support frame 5, on the one hand, the friction between the support frame 5 and the receiving groove can ensure the stability of the support frame in the receiving state, and on the other hand, a space is left for the battery box 6. Since the receiving groove is adapted to the structure of the support frame 5, in order to facilitate pulling out the support frame, a crossbar operating opening is formed at the lower end of the receiving groove, that is, the lower end of the crossbar part of the support frame 5 is exposed, and the operator can easily pull out the entire support frame 5 from the receiving groove through the crossbar 52. Further, the crossbar 52 is provided with anti-skid lines, which not only facilitates the pulling out operation of the support frame 5, but also increases the friction between the support frame 5 and the top surface of the remote control vehicle 1, thereby improving the state stability of the support frame. It should be noted that the two hinges 4 are arranged on the left and right sides of the crossbar operating opening, so they will not be affected by the crossbar operating opening and the crossbar.

[0035] As shown in Figure 2 In order to further improve the convenience of the device, a buckle or magnetic buckle 8 is arranged between the remote controller 2 and the rear end of the remote control vehicle 1, and the buckle or magnetic buckle 8 adopts a conventional structure, which will not be described here. Thus, when the device is stored, the remote controller 2 can also be assembled with the remote control vehicle 1 and the warning sign 3 as a whole, which is convenient to store and also not easy to lose the remote controller.

[0036] As shown in Figure 5 The remote control vehicle 1 generally includes a vehicle body and four walking wheels 11. Considering the passability of the remote control vehicle, the four walking wheels can be arranged on both sides of the vehicle body, that is, extending beyond the coverage of the vehicle body. In this way, the diameter of the walking wheels 11 can be appropriately increased without increasing the size of the vehicle body, so as to effectively cope with the stones or potholes on the road surface.

[0037] Embodiment 2

[0038] Embodiment 1 can meet the use requirements of most conditions, that is, even if the warning sign 3 is blown forward by strong wind, the warning sign 3 can maintain a vertical state and will not continue to rotate forward to maintain the basic warning effect. This embodiment provides a way to further maintain the inclined state of the warning sign. Specifically, the top surface of the remote control vehicle 1 is provided with a positioning groove, and the support frame 5 can be clamped into the positioning groove when it is rotated and extended. The friction between the support frame 5 and the positioning groove can improve the state stability of the warning sign 3 and reduce the possibility of being blown forward by strong wind. At the same time, the warning sign 3 can only be attached to the top surface of the remote control vehicle 1 by gravity in the storage state, and vibration during driving is inevitable. Therefore, the warning sign 3 will constantly collide with the remote control vehicle 1 due to vibration, which not only produces noise but also affects the service life of the device. Therefore, as shown in Figure 6As shown, the positioning block 9 matched with the positioning slot is arranged at the back of the warning board 3, so that the positioning block 9 is just clamped into the positioning slot when the warning board 3 is stored on the top surface of the remote control vehicle 1, and the stability of the storage state of the warning board is ensured. Of course, a storage box with a volume corresponding to the storage state of the device can also be provided for the device to stabilize the storage of the device.

[0039] The above is only a preferred specific embodiment of the present application, which is one implementation based on the overall concept of the present application, and the protection scope of the present application is not limited thereto. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
