Description

Technical Field

[0001] The utility model relates to the technical field of remote control vehicles, in particular to a remote control vehicle capable of expanding remote control relay signals. Background Art

[0002] Remote control cars are model cars that can be controlled remotely by a 2.4GHz radio remote control. They can generally be divided into several categories: toys, car models, police cars, etc. According to the appearance of the car body, they can be divided into: RVs, off-road vehicles, monster trucks, rally cars, container trucks, etc.

[0003] When the user controls the remote control car, the device's internal structure is required to send and receive remote control relay signals;

[0004] First, existing remote control cars are equipped with antennas of fixed length for sending and receiving signals. However, since the length and angle of the antenna are fixed, the device can only send and receive signals within a fixed range, which results in a small distance between the user and the remote control car, making it inconvenient to use.

[0005] Second, the distance between the wheels and the body of the existing remote control car is fixed, and when the user operates the remote control car on a very rugged terrain, it is very easy to cause the chassis to get stuck on the bottom protrusion, resulting in low practicality of the device. Utility Model Content

[0006] The purpose of the utility model is to provide a remote control car capable of expanding remote control relay signals, so as to solve the problems raised in the above-mentioned background technology.

[0008] Preferably, a hollow slot is opened on the top of the fixed shell, the driven gear movably passes through the hollow slot, and the driven gear is rotatably connected to the outside of the vehicle body.

[0009] Preferably, movable blocks are bolted to the bottoms of both sides of the extension rod, movable grooves are opened on both sides inside the fixing rod, and the movable blocks are movably embedded in the movable grooves.

[0010] Preferably, one end of the driving rod away from the rotating motor is rotatably connected to the surface of the vehicle body, a rubber ring is clamped on the top of the extension rod, and the antenna movably passes through the rubber ring.

[0011] Preferably, an adjustment groove is formed at the bottom of the connecting plate, the adjustment plate is movably engaged in the adjustment groove, and a cross bar is bolted between two adjustment plates located on the same side.

[0012] Preferably, an adapter plate is welded to the side of the adjustment plates on the same side that is away from each other, and fixing bolts are bolted to both sides of the adapter plate.

When the antenna rises to its maximum length, the extension rod will be pulled out of the fixed rod to continue extending the length of the antenna. The rotating motor is turned on through the external control terminal to drive the driving gear to rotate through the driving rod. Since the driving gear is meshed with the driven gear and the diameter of the driving gear is smaller than that of the driven gear, the driven gear will be driven to rotate slowly, thereby adjusting the angle of the top antenna. Multiple components cooperate with each other to adjust the extension length and placement angle of the antenna, thereby expanding the receiving and transmitting range of the antenna.

[0016] Second, rotate and remove the fixing bolt, and move the adjustment plate downward within the range of the adjustment slot to increase the distance between the wheel and the vehicle body. When the adjustment plate is moved to the appropriate position, rotate and fix the fixing bolt in the corresponding positioning slot again to fix the position of the wheel. The height-adjustable wheel makes it easier for users to use the device on different terrains, thereby improving the practicality of the device. BRIEF DESCRIPTION OF THE DRAWINGS

The mounting plate 15 is rotatably connected to the wheel 13 on the side away from the vehicle body 1, pulling the antenna 9 upward to make the antenna 9 rise from the extension rod 8. When the antenna 9 rises to the maximum length, the extension rod 8 will be pulled out from the fixed rod 7, thereby continuing to extend the length of the antenna 9. The rotating motor 3 is turned on through the external control terminal to drive the driving gear 5 to rotate through the driving rod 4. Since the driving gear 5 is meshed with the driven gear 6, and the diameter of the driving gear 5 is smaller than that of the driven gear 6, the driven gear 6 will be driven to rotate slowly, thereby adjusting the angle of the top antenna 9. Multiple components cooperate with each other to adjust the extension length and placement angle of the antenna 9, thereby expanding the receiving and transmitting range of the antenna 9.

[0024] Specifically, a slot is opened on the top of the fixed shell 2 , and the driven gear 6 movably passes through the slot, and the driven gear 6 is rotatably connected to the outside of the vehicle body 1 .

[0025] Through the above technical solution, the diameter of the driven gear 6 is larger than that of the driving gear 5 , and the driven gear 6 can rotate slowly when the driving gear 5 rotates.

[0026] Specifically, the bottoms of both sides of the extension rod 8 are bolted with movable blocks 10 , and movable grooves 11 are opened on both sides inside the fixed rod 7 , and the movable blocks 10 are movably embedded in the movable grooves 11 .

The rotating motor 3 is turned on through the external control terminal to drive the driving gear 5 to rotate through the driving rod 4. Since the driving gear 5 is meshed with the driven gear 6 and the diameter of the driving gear 5 is smaller than that of the driven gear 6, the driven gear 6 will be driven to rotate slowly, thereby adjusting the angle of the top antenna 9. The fixing bolt 21 is rotated to remove it, and the adjustment plate 16 is moved down within the range of the adjustment groove 18 to increase the distance between the wheel 13 and the vehicle body 1. When the adjustment plate 16 is moved to an appropriate position, the fixing bolt 21 is rotated and fixed in the corresponding positioning groove 19 again to fix the position of the wheel 13.
