[0015] Beneficial effects of the present invention:

[0016] 1. The present invention utilizes a direction-changing unit and an actuating unit to facilitate the rotation of the wheels, thereby increasing the convenience of transporting camping equipment. The travel unit is mounted on the actuating unit via a coupling unit. The coupling unit includes a pair of bases connected by a connecting block, thereby increasing the rotational mobility of each wheel compared to the supporting unit. When transporting camping equipment over uneven terrain, the geometric angle between each wheel and the supporting unit changes according to the terrain to ensure that the center of the supporting unit remains horizontal. This enhances friction between the wheels and the contact surface, preventing the loaded camping equipment from tipping over. The bracket is detachably mounted on the supporting unit, which holds the fabric cover open to facilitate loading of the camping equipment.

[0017] 2. During the transport of camping equipment, the geometric angles between the wheels and the support unit are adjusted according to the terrain to accommodate uneven terrain. This allows the wheels to abut against the lower support surface, maintaining the horizontality of the support unit and preventing the camping equipment loaded therein from tipping over. This increases the safety of camping equipment loading and transportation. Connecting block 1 is connected to the actuating unit and the travel unit, respectively, and to the first universal joint via a connecting lever 3. This increases the rotatability between the actuating unit and the travel unit, thereby increasing the rotatability between the support unit and the travel unit. Connecting blocks 1 on both sides are connected via the first universal joint, allowing the actuating unit to drive the wheels through the first universal joint and connecting block 1 without hindering the movement of the actuating unit and the travel unit.

[0018] 3. The present invention provides a buffer for the joints between each wheel and the supporting unit by installing a buffer telescopic rod, thereby extending the service life of the device and preventing the device from tipping over. A pair of bases are connected by the buffer telescopic rod, so that the base on one side can move in coordination with the traveling unit according to the terrain. The base on the other side is driven to move by the connecting block and the buffer telescopic rod, so that the actuating unit can perform conversion activities according to the terrain.

[0019] 4. The present invention allows the actuating unit to rotate the wheel through the cooperation of the connecting lever 1 and the connecting lever 4, and allows the angle between the wheel and the actuating unit to be changed according to the terrain through the installation of the steel ring 2 and the base. The actuating member 2 is installed in the installation box, and the transmission head of the actuating member 2 protruding from the installation box is connected to the connecting block 1 on one side. The installation of the buffer connection plate and the base reduces the vibration of the device during transportation on uneven terrain to prevent the device from tipping over. The actuating member 1 is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Through the installation of the actuating member 1, the actuating unit is rotated, and the wheel is rotated through the connecting mechanism, so that each wheel can move according to different terrains.

[0037] The installation of the direction-changing unit 31 and the actuating unit 41 facilitates the rotation of the wheels, thereby increasing the convenience of transporting camping items using the device. The traveling unit 51 is installed on the actuating unit 41 via the connecting unit 61. The connecting unit 61 includes a pair of bases 63, which are connected by a connecting block 64. This increases the rotational mobility of each wheel compared to the supporting unit. When encountering uneven terrain during the transportation of camping items, the geometric angle between each wheel and the supporting unit will be adjusted according to the terrain to ensure that the center of the supporting unit remains horizontal, thereby enhancing the friction between the wheel and the contact surface and preventing the camping items loaded in the device from tipping over.

[0038] The connecting mechanism includes a pair of connecting blocks 2 622 arranged back to back and a pair of connecting blocks 1 623 arranged opposite to each other. One side of the pair of connecting blocks 2 622 is connected via a connecting rod 2 624, and the sides of the pair of connecting blocks 2 622 farther away from each other are respectively connected to a pair of connecting blocks 1 623 via a connecting rod 3 625. One of the connecting blocks 1 623 is connected to the output head 44 of the actuating member 2 43 on the actuating unit 41, and the connecting block 1 623 farther away from the actuating member 2 43 is connected to the traveling unit 51 via a connecting rod 4 626. The actuating member 2 43 is an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. During the transport of camping items, the geometric angles between the wheels and the support unit are adjusted according to the terrain to cope with uneven terrain, allowing the wheels to abut against the lower support surface, maintaining the horizontality of the support unit 21, preventing the camping items loaded in the device from tipping over, and increasing the safety of camping item loading and transportation. The connecting block 1 623 is connected to the actuating unit 41 and the traveling unit 51 respectively, and is connected to the first universal joint yoke 622 via the connecting lever 3 625, thereby increasing the rotational mobility between the actuating unit 41 and the traveling unit 51, thereby increasing the rotational mobility between the supporting unit 21 and the traveling unit 51. The connecting block 1 623 on both sides is connected via the first universal joint yoke 622, allowing the actuating unit 41 to promote the movement of the wheels via the first universal joint yoke 622 and the connecting block 1 623, without hindering the movement of the actuating unit 41 and the traveling unit 51.

[0039] The connecting unit 61 includes a buffer telescopic rod 65, with a connecting bar 634 mounted on the second ring block 632. A pair of buffer telescopic rods 65 are mounted on either side of the base 63, each end of which is screwed to a pair of connecting bars 634 on the base 63. The installation of the buffer telescopic rods 65 provides a buffer at the connection between each wheel and the support unit 21, extending the operating life of the device and helping to prevent it from tipping over. The buffer telescopic rods 65 connect the pair of bases 63, allowing one base 63 to move in conjunction with the travel unit 51 according to the terrain. The base 63 on one side is driven by the connecting block 64 and the buffer telescopic rod 65, allowing the actuating unit 41 to convert according to the terrain.

[0040] Travel unit 51 comprises a steel ring 52, a ring block 53 mounted on one side of steel ring 52, a support ring 54 mounted on the outside of steel ring 52, and an elastic contact layer 55 mounted on the outside of support ring 54. Connecting lever 1 522 is mounted on a portion of steel ring 52 farther from ring block 1 53. Connecting lever 1 522 has a keying recess 523 corresponding to connecting lever 4 626. Connecting lever 1 522 is mounted on the outside of steel ring 522, which is fixedly connected to base 63. The cooperation between connecting lever 1 522 and connecting lever 4 626 causes actuating unit 41 to rotate with the wheel. The connection between steel ring 2 56 and base 63 allows the angle between the wheel and actuating unit 41 to change according to the terrain.

[0041] Actuating unit 41 includes a mounting box 42 and a second actuator 43 mounted within the mounting box 42. A buffer adapter 45, fixedly connected to base 63, is located near the mounting box 42. Actuating unit 43 is mounted within the mounting box 42. A contact 44 of actuator 43, extending from the mounting box 42, connects to a first connector 623 on one side. The buffer adapter 45, attached to base 63, reduces vibration during transport over uneven terrain, preventing the unit from tipping over.

[0042] The direction-changing unit 31 comprises a housing 32, an actuator 33 mounted within the housing 32, a rotating block 34 mounted below the actuator 33, and a connecting plate 35 mounted below the rotating block 34 and connected to the actuator 41. One side of the actuator 33 connects to the bottom of the support unit 21. The actuator 33 is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction. The installation of the actuator 33 causes the actuator 41 to rotate, which in turn causes the wheels to rotate via a coupling mechanism, allowing each wheel to move according to different terrains.

[0043] The supporting unit 21 includes a supporting frame 1 22 and a supporting frame 2 23 mounted on the supporting frame 1 22 . The supporting frame 2 23 is connected to the direction-changing unit 31 . A battery 71 is mounted below the supporting frame 1 22 .

[0044] The connecting block 64 is arched, and the bases 63 on both sides are connected through the connecting block 64, so that the vibration of the wheel when running on uneven terrain is guided to the supporting unit 21 through the connecting block 64. Through the installation of the arched connecting block 64, the vibration on the arched connecting block 64 is guided back and forth, which helps to reduce the vibration, extend the service life of the device, and prevent the device from tipping over.

[0045] The protruding block 633 is provided with a first opening 635, within which a latch 636 is mounted. A rotating base 637 is mounted on the exterior of the latch 636. The connecting block 64 is provided with a second opening 638 corresponding to the first opening 635, allowing the latch 636 to extend into the second opening 638. A pressing block 639 is mounted on the exterior of the connecting block 64. The pressing block 639, the latch 636, and the connecting block 64 are each provided with corresponding through-openings 630, allowing the pressing block 639 to be connected to the latch 636 and the connecting block 64 via bolts. The connection between the pressing block 639, the latch 636, and the connecting block 64 allows the connecting block 64 to rotate in response to the rotating base 637, and the connecting block 64 to rotate in response to the base 63.

[0046] The supporting unit 21 is equipped with a terrain perception unit, a travel planning unit and an operation unit. The terrain perception unit collects scene data of camping transportation through a multimodal sensing element array installed on the supporting unit 21, and is equipped with a depth camera and a lidar to construct a transportation terrain scene model including terrain undulations and obstacle distribution, providing data support for subsequent decision-making. The travel planning unit generates the optimal transportation displacement based on the three-dimensional model transmitted by the terrain perception unit and the terrain scene optimization algorithm. The terrain scene planning takes into account the obstacle avoidance strategy and can avoid obstacles according to the expansion size of the obstacle, so as to facilitate the safe progress of the loading and transportation of camping items. The operation unit drives the multimodal movement of the transportation device according to the dynamic trajectory instructions transmitted by the travel planning unit, including motion mode switching, motion parameter allocation and adaptability to variable terrain. The motion mode switching includes automatic switching between omnidirectional motion mode and differential turning mode.
