The motor interfaces of two two-way electronic speed controllers of the same model are respectively connected to the left and right motors. The interfaces of the two-way electronic speed controllers are respectively inserted into two channels of the receiver. The output end of the battery pack is divided into two groups of interfaces and is respectively connected to the power input ends of the two two-way electronic speed controllers. The working switch wires of the two two-way electronic speed controllers are connected in parallel and are controlled by a main control switch at the same time;
[0005] The frame is connected by square steel. Its top surface is a cross frame and is matched with the vehicle frame of the camping vehicle after it is unfolded. The two ends of the load-bearing rod at the bottom of the camping vehicle frame are fixed at the centers of the square steel on the left and right sides of the cross frame. Below the two sides of the cross frame are vertical frames for installing crawlers. The bottom of the vertical frames is connected by a cross bar. The space formed by the cross frame and the vertical frames is used to install the storage box; The storage box is provided with notches that match the positions of the rod bodies on the frame;
[0006] The remote control electronic module is installed in the storage box, and the motor is connected to the driving wheel of the crawler. The axle of the load-bearing wheel of the crawler is fixed to the square steel at the bottom of the vertical frame.
[0007] Further, after the vehicle frame of the camping vehicle is unfolded, it is fixed to the front and rear square steel of the cross frame through screws and wing nuts.
[0008] Further, the remote control electronic module is controlled by a plate-type remote control transmitter or a gun-type remote control transmitter.
[0009] The beneficial effects of the present utility model are as follows: The chassis is installed at the bottom of the camping vehicle, adopts wireless remote control, is powered by a battery pack, and uses a motor to provide driving force, reducing manual operation; it can overcome various road surfaces, such as grasslands, dirt roads, and gravel roads, and can easily cross ditches and ridges; the combination design of the chassis and the carriage is quick-release, facilitating storage; the crawler is light in weight, low in cost, low in noise, and can also tow other small vehicles.

[0017] Embodiment 1: The crawler-type self-propelled camping vehicle chassis is arranged at the bottom of the camping vehicle 1. The camping vehicle 1 includes a foldable frame and a cloth bag. The chassis includes a frame 2, a storage box 3, a crawler 4, and a remote control electronic module 5. Among them, the remote control electronic module 5 includes a two-way electronic speed governor 51, a motor 54, a receiver 52, and a battery pack 53. The motor interfaces of two two-way electronic speed governors 51 of the brand SKYWIN and model sky320A are respectively connected to the left and right motors 54. The interfaces of the two-way electronic speed governors 51 are respectively inserted into two channels of the receiver 52. The output end of the battery pack 53 is divided into two groups of interfaces, which are respectively connected to the power input ends of the two two-way electronic speed governors 51. The working switch wires of the two two-way electronic speed governors 51 are connected in parallel and controlled by a main control switch 55 at the same time;
[0018] The frame 2 is formed by connecting square steel. Its top surface is a cross-frame and matches the vehicle frame of the camper 1 after it is unfolded. Both ends of the load-bearing rod at the bottom of the vehicle frame of the camper 1 are fixed at the centers of the square steel on the left and right sides of the cross-frame. After the vehicle frame is unfolded, it is fixed on the front and rear square steel of the cross-frame through screws and wing nuts. Below both sides of the cross-frame are vertical frames for installing crawlers. The bottoms of the vertical frames are connected by cross bars.
