[0031] The following combination Figures 1 to 8 The specific structure and working process of the unmanned all-terrain vehicle of the present invention are described.

[0032] One embodiment of the present invention provides an unmanned all-terrain vehicle. Figure 1As shown, it includes an all-terrain vehicle chassis 1, an all-terrain vehicle frame 2, a traveling mechanism connected to the all-terrain vehicle chassis 1, and a power drive system for driving the traveling mechanism, and also includes an unmanned steering system 3, an unmanned braking system 4 and an unmanned control system 5, wherein the unmanned steering system 3 is connected to the traveling mechanism to perform steering control on the traveling mechanism; the unmanned braking system 4 is connected to the traveling mechanism to perform braking control on the traveling mechanism; the unmanned control system 5 is arranged on the top of the all-terrain vehicle frame 2, and the unmanned control system 5 is electrically connected to the power drive system, the unmanned steering system 3 and the unmanned braking system 4, respectively, for identifying driving area information and issuing control instructions to control the power drive system, the unmanned steering system 3 and the unmanned braking system 4.

[0033] It can be understood that the unmanned all-terrain vehicle of this embodiment is designed to be unmanned. The steering wheel structure of the traditional all-terrain vehicle is replaced by the unmanned steering system 3, the braking system of the traditional all-terrain vehicle is replaced by the unmanned braking system 4, and an unmanned control system 5 is added to control the power drive, steering and braking of the all-terrain vehicle, thereby realizing unmanned operation of the all-terrain vehicle. The intelligence level of the all-terrain vehicle is greatly improved, and unmanned all-terrain vehicle operation can be realized in various scenarios such as emergency rescue, material transportation, border patrol, tourism and entertainment.

[0034] In some embodiments of the unmanned all-terrain vehicle of the present invention, see Figure 2 As shown, the unmanned steering system 3 includes a steering motor 31, a steering gear shaft 32, a steering gear 33, a first connecting rod 34 and a steering controller, wherein the steering motor 31 is fixed to the all-terrain vehicle chassis 1; the steering gear shaft 32 is connected to the rotating shaft of the steering motor 31 through a universal joint; the steering gear 33 is meshed with the gear on the steering gear shaft 32; one end of the first connecting rod 34 is rotatably connected to the end face of the steering gear 33, and the other end is connected to the walking mechanism; the steering controller is electrically connected to the unmanned control system 5 and the steering motor 31 to receive control instructions from the unmanned control system 5 and control the steering motor 31.

[0035] It can be understood that the unmanned steering system 3 of the unmanned all-terrain vehicle of this embodiment controls the operation of the steering motor 31 through the unmanned control system 5. The steering motor 31 drives the steering gear shaft 32 to rotate through the universal joint. During the rotation of the steering gear shaft 32, the steering gear 33 engaged with it rotates. The steering gear 33 is connected to the walking mechanism of the unmanned all-terrain vehicle through the first connecting rod 34. The rotation of the steering gear 33 causes the walking mechanism to turn during the walking process.

[0036] Specifically, in some specific examples, the walking mechanism includes a set of opposite tires, see Figure 2As shown, the steering gear 33 is located between the two running tires. A rotating shaft is provided on the end face of the steering gear 33. There are two first connecting rods 34. One end of each first connecting rod 34 is movably mounted on the rotating shaft on the end face of the steering gear 33, and the other end is connected to one of the tires of the running mechanism. It is understood that the two first connecting rods 34 are connected to the two running tires. As the steering gear 33 rotates, the two first connecting rods 34 will move toward one side of the all-terrain vehicle, thereby pulling or pushing the two running tires to deflect in direction, thereby achieving the purpose of steering. It should be understood that the two running tires involved in this example can be the two front wheels of the all-terrain vehicle, or the two rear wheels of the all-terrain vehicle, or both the front and rear wheels can be equipped with the unmanned steering system 3, so that unmanned steering of the all-terrain vehicle can be achieved.

[0037] In other embodiments of the unmanned all-terrain vehicle of the present invention, the unmanned braking system 4 includes a first brake pump 41, a brake drive mechanism 42, a second brake pump 43 and a brake controller 44, wherein the first brake pump 41 is filled with brake oil; the brake drive mechanism 42 is used to drive the first brake pump 41 to pump out brake oil; the second brake pump 43 is connected to the first brake pump 41, and the second brake pump 43 is connected to a brake pad, which is used to squeeze the brake disc of the walking mechanism; the brake controller 44 is electrically connected to the unmanned control system 5 and the brake drive mechanism 42 to receive control instructions from the unmanned control system 5 and control the brake drive mechanism 42.

[0038] See also Figure 3 As shown, after the unmanned control system 5 issues a braking signal based on the current driving speed and braking distance, the brake controller 44 controls the brake drive mechanism 42 to operate. The brake drive mechanism 42 drives the first brake pump 41 to press brake fluid, which then enters the second brake pump 43. This controls the brake pads on the second brake pump 43 to press against the brake discs on the all-terrain vehicle wheels to achieve braking. A second brake pump 43 can be provided for each of the four wheels of the all-terrain vehicle. The brake fluid pressed by the first brake pump 41 enters the four second brake pumps 43 in equal amounts, respectively braking the four wheels of the all-terrain vehicle.

[0039] Specifically, in some specific examples, see Figure 4As shown, the brake drive mechanism 42 includes a mounting seat 421, a servo push rod motor 422, an articulated seat 423 and a second connecting rod 424, wherein the mounting seat 421 is fixed on the all-terrain vehicle chassis 1; the servo push rod motor 422 is a linear motor, mounted on the mounting seat 421; the articulated seat 423 is fixed to the mounting seat 421; the middle part of the second connecting rod 424 is rotatably connected to the articulated seat 423, one end of the second connecting rod 424 is articulated to the output shaft of the servo push rod motor 422, and the other end is articulated to the push rod 425, and the push rod 425 is connected to the pump rod of the first brake pump 41. It can be understood that after the brake controller 44 receives the brake signal given by the unmanned control system 5, the brake controller 44 controls the output shaft of the servo push rod motor 422 to extend a specified length, and the output shaft of the servo push rod motor 422 drives the second connecting rod 424 to rotate around the hinge seat 423. The other end of the second connecting rod 424 pushes the push rod 425 toward the first brake pump 41, squeezing the pump rod of the first brake pump 41, so that the first brake pump 41 pumps brake oil to the second brake pump 43, and the brake pads on the second brake pump 43 squeeze the brake disc on the wheel to complete the braking process.

[0040] In some embodiments of the unmanned all-terrain vehicle of the present invention, Figure 5 and Figure 6 As shown, the unmanned control system 5 includes a base plate 51, a navigation device 52, a laser radar 53, a computing module 54 and a power module 55, wherein the base plate 51 is fixed to the top of the all-terrain vehicle frame 2; the navigation device 52 is arranged inside the base plate 51, for storing the destination position information of the unmanned all-terrain vehicle and obtaining the current position information of the unmanned all-terrain vehicle; the laser radar 53 is arranged at the front end of the base plate 51, for obtaining the environmental information around the unmanned all-terrain vehicle; the computing module 54 is arranged inside the base plate 51, and the computing module 54 is electrically connected to the navigation device 52 and the laser radar 53 to receive the information obtained by the navigation device 52 and the laser radar 53 and perform calculations to generate control instructions; the power module 55 is used to supply power to the unmanned control system 5.

[0041] It will be appreciated that in the structure of the unmanned control system 5 in this embodiment, the power module 55 may include a battery pack or other type of power supply to power the unmanned control system 5. The baseplate 51 is mounted on top of the ATV frame 2 and serves as a base platform for mounting other components (such as the navigation device and computing module). The navigation device 52 is located within the baseplate 51 and can use GPS or other positioning technologies to determine the vehicle's location. The laser radar 53 is located at the front of the baseplate 51 and is used to obtain environmental information surrounding the unmanned ATV, such as the distance and direction of obstacles. By emitting laser beams and measuring the time it takes for them to reflect back, it can construct a three-dimensional image of the surrounding environment. The computing module 54 is located within the baseplate 51 and receives data from the navigation device 52 and the laser radar 53. It performs necessary calculations, such as path planning and obstacle avoidance decisions, and generates control instructions to guide the actions of the unmanned ATV. The unmanned control system 5 in this embodiment enables the unmanned all-terrain vehicle to drive autonomously in complex environments. It determines the target position through the navigation device, uses the laser radar 53 to perceive obstacles in the surrounding environment, and then uses the computing module 54 to process this information and make corresponding decisions. This design can adapt to various terrain conditions and has a certain degree of flexibility and autonomy.

[0042] In some examples, the laser radar 53 includes a drivable area detection laser radar 531 and a multi-line laser radar 532. The drivable area detection laser radar 531 is located at the front end of the base plate 51 and is used to detect the drivable area in front of the unmanned all-terrain vehicle. This type of laser radar generally has a wide horizontal field of view so that it can cover a larger area, helping the all-terrain vehicle identify which areas ahead can be safely passed. The multi-line laser radar 532 is located on the upper front end of the base plate 51 and is used to obtain a three-dimensional image of the environment surrounding the unmanned all-terrain vehicle. The multi-line laser radar 532 has multiple vertically arranged laser emitters that can simultaneously emit laser beams from different angles, thereby obtaining richer three-dimensional point cloud data, facilitating the construction of an accurate three-dimensional environmental model. By combining two different types of laser radars 53, the unmanned all-terrain vehicle can not only detect the drivable area ahead, but also obtain detailed information about the surrounding environment, which is beneficial to the vehicle's autonomous navigation and obstacle avoidance.

[0043] Furthermore, the unmanned control system 5 also includes a switch 56, two antennas 57 and multiple cameras 58, wherein the switch 56 is interconnected with the various components of the unmanned control system 5 and is used for communication between the various components of the unmanned control system 5; the two antennas 57 are respectively arranged on the front and rear sides of the substrate seat 51, for receiving and sending wireless signals, so as to realize signal interaction between the unmanned all-terrain vehicle and the remote control center; the multiple cameras 58 are arranged on the side of the substrate seat 51 along the circumference of the substrate seat 51, for obtaining image information around the unmanned all-terrain vehicle.

[0044] Combine Figure 5 and Figure 6 As shown, eight cameras 58 are provided on the base plate 51, which are respectively provided on the front, rear, left and right sides of the base plate 51, so as to obtain image information of the surrounding environment of the unmanned all-terrain vehicle, and transmit the image information to the remote control center through the antenna 57 based on the signal communication of the switch 56. The staff of the remote control center can view the environment around the unmanned all-terrain vehicle in real time, and can remotely control the unmanned all-terrain vehicle by establishing remote communication with the antenna 57.

[0045] Based on the unmanned all-terrain vehicles of the above embodiments, in some embodiments of the unmanned all-terrain vehicles of the present invention, see Figure 7 As shown, the ATV chassis 1 is provided with expansion space, and the unmanned control system 5 has a reserved extended load interface. In this embodiment, other functional modules, such as a reconnaissance module and a weapon station, can be installed in the expansion space on the ATV chassis 1. These expanded functional modules can be controlled through the reserved extended load interface of the unmanned control system 5. Of course, the expansion space on the ATV chassis 1 can also be used as a cargo transport platform. After the unmanned transformation, the vehicle's transportation capacity is significantly improved.

[0046] In other embodiments of the unmanned all-terrain vehicle of the present invention, see Figure 8 As shown, the all-terrain vehicle chassis 1 is provided with seats, which can be used for sightseeing in unmanned scenarios or transporting battlefield casualties. The seating layout can be face-to-face, suitable for sightseeing, or single or double rows facing forward, suitable for emergency transport scenarios. The specific number of seats can be determined according to the size and purpose of the vehicle.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present invention.
