[0047] See also Figures 1 to 6 Embodiment 1 of the present utility model provides a remote-controlled vehicle for engineering use, comprising:

[0048] The vehicle body frame 10, as the support structure of the whole vehicle, ensures the overall stability of the remote control car. There is an installation platform 11 in the middle of the vehicle body frame 10, which is convenient for centrally arranging the core components and improving the space utilization rate. At the front and rear ends of the vehicle body frame 10, there are respectively a front straight axle member 12 and a rear straight axle member 13.

[0055] In this embodiment, please refer to Figures 3 to 5, load-bearing bridge members 90 are fixedly installed on both the front straight bridge member 12 and the rear straight bridge member 13. The load-bearing bridge members 90 are connected to the vehicle body frame 10 through suspension damping members 20. The load-bearing bridge members 90 are in the shape of an arch bridge, which optimizes the weight distribution, effectively buffers the vibrations during driving, and ensures the smoothness of the vehicle body. The steering control member 80 is installed on the load-bearing bridge member 90 of the front straight bridge member 12. This configuration optimizes the installation layout, shortens the action transmission distance between the steering control member 80 and the steering control mechanism 30, improves the execution efficiency of the steering control member 80, and ensures the flexibility and accuracy of the steering operation. The suspension damping members 20 are arranged at both the front and rear ends of the vehicle body frame 10 and are symmetrically distributed on both sides of the vehicle body frame 10. This layout maximizes the damping effect and ensures that the remote control car can maintain good stability and safety at various speeds. The steering control mechanism 30 is arranged on the side of the front straight bridge member 12 away from the driving component 40, effectively avoiding the mutual interference between power transmission and the steering system, and ensuring the independence and smoothness of the steering action.

[0056] The load-bearing bridge member 90 includes a connecting portion 91 and fixing portions 92 provided at both ends of the connecting portion 91. This design makes the load-bearing bridge member 90 structurally stable and easy to install and maintain. A connecting rotating rod 911 protrudes from one side of the connecting portion 91 close to the driving component 40, and a connecting convex column 921 protrudes from one side of the fixing portion 92 away from the connecting rotating rod 911. The suspension damping members 20 each include a damping arm rod 21, a first elastic arm 22, and a second elastic arm 23. One end of the damping arm rod 21 is fixedly connected to the vehicle body frame 10 through a connecting fastening block 24, and the other end of the damping arm rod 21 is installed on the connecting convex column 921, ensuring the stability and reliability of the damping arm rod 21. The second elastic arm 23 is located below the first elastic arm 22 and is arranged at an acute angle to the first elastic arm 22. Such a layout optimizes the damping performance and enhances the response speed of the damping system. One ends of the first elastic arm 22 and the second elastic arm 23 are rotatably installed on the vehicle body frame 10. The other end of the first elastic arm 22 is rotatably installed on the connecting rotating rod 911, and the other end of the second elastic arm 23 is rotatably installed on the connecting convex column 921 and is located between the damping arm rod 21 and the fixing portion 92, ensuring the synchronism of the damping system during steering and also guaranteeing the compactness and stability of the structure.

[0057] The connecting fastening blocks 24 symmetrically distributed on both sides of the vehicle body frame 10 are also connected through a bridging cross beam 14. This design not only enhances the overall rigidity of the vehicle body frame 10 but also improves the torsional resistance of the structure. Installation convex blocks 141 protrude from both ends of one side of the bridging cross beam 14, and an indicator light member 142 is inserted and installed on the installation convex blocks 141. The setting of the installation convex blocks 141 makes the installation of the indicator light member 142 more convenient and fast. At the same time, the setting of the indicator light member 142 effectively improves the visibility of the remote control car at night or in a poor visibility environment and enhances the driving safety.

[0058] Further, please refer to Figure 6 , the transmission universal joint 41 is drivingly connected to the transmission axle 131 through a transmission bevel gear assembly 132. This design realizes the efficient and smooth transmission of power from the driving component 40 to the transmission axle 131. An accommodation cavity 133 corresponding to the transmission bevel gear assembly 132 is provided inside the rear straight axle member 13, providing an accurate installation space for the transmission bevel gear assembly 132 and ensuring the accuracy and reliability of the transmission. The transmission bevel gear assembly 132 includes a first transmission bevel gear 1321 and a second transmission bevel gear 1322. The first transmission bevel gear 1321 is meshingly connected to the second transmission bevel gear 1322, realizing the conversion and transmission of power, and having the characteristics of high transmission efficiency and low noise. The first transmission bevel gear 1321 is installed on the transmission axle 131, ensuring the effective output of power. The first transmission bevel gear 1321 is installed at one end of the transmission universal joint 41 away from the driving component 40. Such a layout makes the transmission path more reasonable, reduces the loss during power transmission, and is convenient for subsequent maintenance and repair work.

[0059] Please refer to Figure 3 and Figure 4 , mounting slots 15 are provided at both ends of the front straight axle member 12. One end of the adjustable deflection member 121 is movably installed on the mounting slot 15 through a steering connecting member 123, and the front wheel 50 is installed on the other end of the adjustable deflection member 121. The design of the mounting slot 15 facilitates the quick installation and disassembly of the adjustable deflection member 121, improving the maintenance efficiency. The setting of the steering connecting member 123 ensures the flexibility and stability of the front wheel 50 during steering, meeting the driving requirements of the remote control car under different road conditions. The steering control mechanism 30 includes a connecting rod 31. A rod mounting portion 122 protrudes from one side of the adjustable deflection member 121 away from the front straight axle member 12. Both ends of the connecting rod 31 are respectively rotatably installed on the rod mounting portions 122 of the two adjustable deflection members 121. Among them, the rod mounting portion 122 provides a stable connection point, ensuring the stable installation of the connecting rod 31. An operating rod 32 is also installed at one end of the connecting rod 31, and the operating rod 32 is connected to the transmission end of the steering control member 80.

[0060] It should be noted that the connecting rod 31 realizes the synchronous control of the deflection angle of the front wheel 50 through mechanical connection. The design of the operating rod 32 facilitates the direct control of the steering of the front wheel 50 by the steering control member 80, ensuring the accurate transmission and execution of the steering command.

[0061] Please refer to Figure 2 , a groove 111 is also provided at the bottom end of the mounting platform 11. A switch control member 112 is provided in the groove 111, and the switch control member 112 is used to control the on / off of the power supply of the remote control car, improving the convenience and safety of use.

[0066] Embodiment 2

[0067] Please refer to Figure 7 , Embodiment 2 of the present utility model provides a remote control device for sending control instructions to the engineering remote control vehicle. Through the operation of the remote control device, remote control and adjustment of the motion state of the remote control vehicle are realized, improving the flexibility and efficiency of work.

[0068] Specifically, turn on the power switch of the remote control device. At this time, the signal lamp set on the remote control device flashes. Then turn on the switch control 112 of the engineering remote control vehicle to make the circuit of the engineering remote control vehicle conduct. At this time, the indicator lamp 142 of the engineering remote control vehicle flashes and automatically pairs with the remote control device. There is also a voice prompt in the engineering remote control vehicle. When the pairing is successful, the voice prompt on the engineering remote control vehicle emits a prompt sound to indicate that the pairing is successful.

[0069] Rotate the steering handwheel 60 set on the remote control device to adjust the steering of the front wheels 50. Then pull the trigger 70 on the remote control device to make the engineering remote control vehicle move forward. When quickly returning to the center and pushing the trigger 70, the braking function of the engineering remote control vehicle is realized. When slowly returning to the center and pushing the trigger 70, the engineering remote control vehicle moves backward.

[0070] The remote control device is also provided with an ST knob, a CH3 button and a TH knob. When the engineering remote control vehicle moves forward, if the body of the engineering remote control vehicle deviates to the left from a straight line, turn the ST knob to the right; if the body of the engineering remote control vehicle deviates to the right from a straight line, turn the ST knob to the left until the engineering remote control vehicle can move straight. In addition, the traveling speed of the engineering remote control vehicle can be adjusted by the TH knob to meet the requirements of different road surfaces. When encountering a special environment, such as a rocky road surface being rough and the engineering remote control vehicle having less power and being unable to climb up. For this reason, long-press the CH3 button for 1 second to make the engineering remote control vehicle enter the high-speed and strong climbing mode, and at this time, the signal lamp on the remote control device flashes quickly. When the CH3 button is long-pressed again for 1 second, the engineering remote control vehicle switches to the flat road mode, and at this time, the signal lamp on the remote control device is always on.

[0071] It should be noted that by pressing the CH3 button, the adjustment of the driving component 40 of the engineering remote control vehicle is realized, and a larger torque is obtained by motor frequency conversion.

[0072] In addition, it should be clear that in the normal power-on state, the engineering remote control vehicle is in the flat road mode, and the motor driving frequency of the driving component 40 is 1000 hz. By long-pressing the CH3 button for 1 second, the signal lamp on the remote control device flashes quickly, and the engineering remote control vehicle enters the rock climbing mode. At this time, the motor driving frequency is 200 hz and the torque becomes larger.

[0073] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the principles of the present invention shall be included within the protection scope of the present invention.
