[0014] Compared with existing technologies, the present invention, a desert collaborative transport vehicle and system, has the following advantages: The present invention sets up a load-bearing support and two intelligent agents.

The vehicle comprises an upper leg arm, a lower leg arm, a first electric cylinder, wheel seats, a wheel steering motor, a wheel frame, a wheel-side motor, and wheels. The leg seat is hinged to the vehicle body via a vertical shaft, and a steering gear is fixed on the leg seat.

The upper half of the T-shaped slide rail is located on the upper side of the slide. When the T-shaped slide rail is in place, the positioning block extends and engages with the positioning groove, thus establishing a stable connection between the intelligent agent and the load support, thereby achieving the purpose of automatic assembly. The automatic unloading process is the reverse of the automatic assembly process and will not be described in detail here.

[0024] First, it should be noted that the directional terms such as up, down, left, right, front, and back used in this invention are merely descriptions based on the accompanying drawings for ease of understanding, and are not intended to limit the technical solution or the scope of protection claimed in this invention.

[0025] like Figures 1 to 8The embodiment of a desert collaborative transport vehicle of the present invention shown includes a load support 1 and two intelligent agents. The load support 1 adopts an arc-shaped structure, and two symmetrically distributed grooves 11 along its length are provided on the load support 1. A slide rail 12 is provided on the inner half side wall of the groove 11, and a positioning groove 13 is provided on the side wall of the groove 11 above the slide rail 12. The two intelligent agents are arranged one-to-one with the two slide rails 11 of the load support 1, and the intelligent agents are equipped with a vehicle body 2 and four wheel legs 3. A docking seat 4 that mates with the load support 1 is provided on the vehicle body 2, and a T-shaped slide rail 41 that mates with the slide rails 11 and 12 is provided on the docking seat 4. A retractable positioning block 42 that mates with the positioning groove 13 is provided on the side wall of the T-shaped slide rail 41. Four wheel legs 3 are installed at the four corners of the vehicle body 2. Each wheel leg 3 includes a leg seat 31, an upper leg arm 32, a lower leg arm 33, a first electric cylinder 34, a wheel seat 35, a wheel steering motor 36, a wheel frame 37, a wheel-side motor 38, and a wheel 39. The leg seat 31 is hinged to the vehicle body 2 via a vertical shaft. A steering gear 311 is fixed on the leg seat 31. The vehicle body 2 is equipped with a leg steering motor (not shown in the figure). A drive gear (not shown in the figure) that meshes with the steering gear 311 is fixed on the output shaft of the leg steering motor. One end of the upper leg arm 32 and the lower leg arm 33 are respectively hinged to the leg seat 31 via a horizontal shaft. The other end of the upper leg arm 32 and the lower leg arm 33 are respectively hinged to the wheel seat 35 via a horizontal shaft. The two ends of the first electric cylinder 34 are respectively hinged to the middle of the lower leg arm 33 and the leg seat 31 via a horizontal shaft. The wheel steering motor 36 is vertically mounted on the wheel seat 35. The wheel frame 37 is fixedly connected to the output shaft of the wheel steering motor 36. The wheel-side motor 38 is horizontally fixed on the wheel frame 37. The wheel 39 is coaxially fixed on the output shaft of the wheel-side motor 38.

[0026] The above structural configuration constitutes a desert collaborative transport vehicle with good passability, strong adaptability, high safety, and stable reliability. In practical applications, the load can be placed on the load carriers 1 of two or more transport vehicles as needed, and the load can be transported in the desert environment through the coordinated operation of all transport vehicles. Compared with wheeled or tracked vehicles, it improves the adaptability to the desert environment and the passability on rugged and undulating roads, ensuring the stability and reliability of load transportation. This invention configures the wheel legs 3 with a leg seat 31, upper leg arm 32, lower leg arm 33, first electric cylinder 34, wheel seat 35, wheel steering motor 36, wheel frame 37, wheel-side motor 38, and wheel 39. The wheel steering motor and drive gear drive the steering gear 311 to rotate, which allows the wheel legs 3 to swing laterally. The extension and retraction of the first electric cylinder 34 allows the wheel legs 3 to swing vertically. The rotation of the wheel steering motor 36 allows the wheel frame 37, wheel-side motor 38, and wheel 39 to turn together. The rotation of wheel 38 enables the wheels to roll and move. By comprehensively controlling the aforementioned movements of the four wheel legs 3, the intelligent entity can perform omnidirectional posture adjustments such as lateral movement, longitudinal movement, lifting, flipping, and turning in place. With road surface sensing devices installed on each wheel leg 3, for rugged desert terrain, controlling the wheels 39 of each wheel leg 3 to undulate at different heights ensures that all wheels 39 of the intelligent entity remain attached to the ground, improving obstacle-crossing ability. By enabling all the intelligent entities of the transport vehicle to operate in coordination, the stability and safety of load transportation can be effectively guaranteed. Simultaneously, by setting up a load support 1 and a docking seat 4 that mates with the intelligent entity, combined with the intelligent entity's omnidirectional posture adjustment function and the visual sensing device installed on the docking seat 4, automatic assembly and unloading can be achieved, improving functionality and practicality. The specific processes of automatic assembly and automatic unloading are as follows: During assembly, each intelligent entity adjusts its posture, and the T-shaped slide rail 41 of its respective docking seat 4 slides gradually from the outside to the inside into the corresponding slide groove 11 of the load support 1. The upper half of the T-shaped slide rail 41 is located on the upper side of the slide rail 12. After the T-shaped slide rail 41 slides into place, the positioning block 42 extends and engages with the positioning groove 13, thus establishing a stable connection between the intelligent entity and the load support 1, achieving the purpose of automatic assembly. The automatic unloading process is the reverse of the automatic assembly process and will not be described further here. It should be noted that, to ensure the stability of the structure and docking, in practical applications, the upper side of the docking seat 4 and the T-shaped slide rail 41 are set as an arc-shaped structure matching the upper 1 of the load support. Furthermore, it should be pointed out that the aforementioned road surface sensing device and visual sensing device are commonly used devices in the field. How to control the intelligent entity and transport vehicle based on the detection parameters of the sensing device and visual sensing device can be achieved through various strategies, which are well known to those skilled in the art and are not the subject of this invention, and will not be described further here.

[0027] As an optimized solution, this specific embodiment includes a chassis 21 and a car body 22 fixed on the chassis 21 to simplify the structure and manufacturing process. A limiting groove 221 is provided on one side of the car body 22, and shaft holes 222 are provided on the two end walls of the limiting groove 221. Correspondingly, the docking seat 4 is fitted into the limiting groove 221, and rotating shafts 43 located in the shaft holes 222 are provided at both ends of the docking seat 4. This structural design allows the docking seat 4 to rotate slightly in the limiting groove 221, effectively avoiding jamming during automatic assembly and unloading, and ensuring stable and reliable operation. As an optimized solution, this specific embodiment also fixes arc-shaped racks 14 on both sides of the load support 1. Correspondingly, assist gears 44 that cooperate with the arc-shaped racks 14 are installed on both sides of the T-shaped slide rail 41 of the docking seat 4, and a gear transmission mechanism that drives the assist gears 44 to rotate is provided in the docking seat 4. This structure, designed for automatic assembly and unloading, provides auxiliary propulsion through the cooperation of the assist gear 44 and the arc-shaped rack 14, enhancing the stability and reliability of the operation. It should be noted that in practical applications, the present invention typically uses thrust cylindrical roller bearings to mount the assist gear 44 to ensure smooth rotation. The gear transmission mechanism can adopt the following structure: a servo motor is installed in the docking seat 4, and a driving bevel gear is installed on the output shaft of the servo motor. Driven bevel gears meshing with the driving bevel gears are respectively installed on the central shafts of the two assist gears 44. Thus, the servo motor drives the driving bevel gear to rotate, and with the cooperation of the driven bevel gears, the two assist gears 44 can rotate synchronously. However, it should be pointed out that the gear transmission mechanism is not limited to the above-listed forms and other structures with equivalent functions can also be used. To enable the positioning block 42 to achieve its telescopic function, the present invention also provides a second electric cylinder in the docking seat 4 to drive the positioning block 42. The specific configuration of the second electric cylinder is well known to those skilled in the art and will not be described further here.

A sand outlet spiral device 59 is provided in the sand outlet pipe 56, and the two ends of the sand outlet spiral device 59 are connected to the upper rotating block 581 on the sand-dredging motor 51 and the end cap 58, respectively. This structure allows for the extraction of sand from under the transport vehicle and load via the sand inlet pipe 52, reducing their height. Once the height of the transport vehicle and load meets requirements, the sand outlet pipe 56 covers them with sand, effectively improving concealment and safety. As an optimization, to facilitate control of the sand inlet pipe 52 and the sand outlet pipe 56 and improve the efficiency of sand extraction and sand covering, the invention includes robotic arms 6 on the upper and lower sides of the chassis 21, respectively, for clamping the sand outlet pipe 56 and the sand inlet pipe 52. The robotic arm 6 specifically includes a base 61, an electrically controlled rotary table 62, a primary extension arm 63, and a secondary extension arm 64. The base 61 is fixed to the chassis 21. The electrically controlled rotary table 62 is mounted on the chassis 21. A primary motor 65 and a secondary motor 66 are fixed to one end of the electrically controlled rotary table 62 and one end of the secondary extension arm 64, respectively. The two ends of the primary extension arm 63 are fixedly connected to the output shafts of the primary motor 65 and the secondary motor 66, respectively. The secondary extension arm 64 is provided with a pipe through-hole 641 and a pipe control port 642. The sand discharge pipe 56 passes sequentially through the pipe through-hole 641 of the base 61, the electrically controlled rotary table 62, and the secondary extension arm 64 on the upper side of the chassis 21 and connects to the pipe control port 642. The sand inlet pipe 52 passes sequentially through the pipe through-hole 641 of the base 61, the electrically controlled rotary table 62, and the secondary extension arm 64 on the lower side of the chassis 21 and connects to the pipe control port 642. The robotic arm 6 of this structure is characterized by its simple structure, convenient operation, and flexible movement. The rotation of the electrically controlled rotary table 62 can turn the first-stage arm 63 and the second-stage arm 64. The rotation of the first-stage motor 65 can extend and retract the first-stage arm 63. The rotation of the second-stage motor 66 can extend and retract the second-stage arm 64. By comprehensively controlling the electrically controlled rotary table 62, the first-stage motor 65, and the second-stage motor 66 of the corresponding robotic arm 6, the position and attitude of the sand inlet pipe 52 and the sand outlet pipe 56 can be precisely controlled.

To facilitate braking and maintain stability, this embodiment provides a wheel steering brake 371 between the wheel seat 35 and the wheel frame 37, and a boom steering brake 621 between the base 61 and the electrically controlled rotary table 62.
