DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0026] Example:

[0027] See also Figure 1 、 Figure 3 、 Figure 4 A mobile vehicle for equipment rental includes a frame 1 and a battery 2 provided on the back of the frame 1.

[0028] The frame 1 is made of high-strength steel and has sufficient load-bearing capacity and deformation resistance. The shape and size of the frame 1 are customized according to the type and size of the rental equipment to ensure that the frame 1 is compatible with most mechanical equipment.

[0029] Battery 2 utilizes a high-performance, long-life lithium-ion battery with advantages such as large capacity, light weight, and fast charging. Mounted on the back of frame 1 via a fixed bracket, Battery 2 facilitates easy replacement and charging. It also provides power for the various electric mechanisms on the mobile vehicle, ensuring its convenience and environmental friendliness.

[0030] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5A mobile vehicle for equipment rental, wherein a top plate 3 is fixed with bolts at the top of a frame 1, a lifting mechanism 4 is installed on the top plate 3 and the frame 1, a moving mechanism 5 is integrally formed on the side wall of the frame 1, and a stabilizing mechanism 6 is provided on the inner wall of the moving mechanism 5; the lifting mechanism 4 includes a driving motor 41, a ball screw 42, a ball nut 43, two guide columns 44, four fixing blocks 45, a bearing seat 46 and a carrier 47; the carrier 47 includes a moving plate 471, two sliders 472, a plurality of connecting rods 473 and two plug plates 474; the moving mechanism 5 includes two mounting shells 51, a plurality of hemispherical grooves 52, a plurality of moving balls 53, two bottom plates 54, a plurality of limiting holes 55 and a plurality of locking bolts 56; the stabilizing mechanism 6 includes two sets of telescopic motors 61 and two splints 62.

[0031] Among them, the top plate 3 is firmly installed on the top of the frame 1 by bolts. This design not only ensures the stability of the structure, but also greatly facilitates the installation and disassembly process of the drive motor 41.

[0032] The lifting mechanism 4 is responsible for raising and lowering the mechanical equipment. The drive motor 41 is bolted to the surface of the top plate 3 and electrically connected to the battery 2, providing the power source for the lifting mechanism 4. The top end of the ball screw 42 is fixedly connected to the output end of the drive motor 41 via a coupling, and the bottom end is fixedly connected to the inner ring of the bearing seat 46. The rotational motion of the ball screw 42 converts the axial motion of the drive motor 41 into linear motion, causing the ball nut 43 to move up and down. The inner wall of the ball nut 43 is connected to the outer wall of the ball screw 42 through a ball-shaped connection, achieving efficient and smooth linear motion. Two guide columns 44 are fixed to the outer wall of the frame 1 and maintained at equal intervals by fixing blocks 45. The guide columns 44 provide a stable upward and downward sliding track for the load 47. Four fixing blocks 45 are connected to the two ends of the two guide columns 44 to ensure the stability of the guide columns 44. The bearing seat 46 is fixed to the outer wall of the frame 1, supporting the bottom end of the ball screw 42 and ensuring its stable rotation. The object carrier 47 is mounted on the ball nut 43 and the guide column 44 and is used to carry the rental equipment. The object carrier 47 is a key component of the lifting mechanism 4, and its design ensures that the rented mechanical equipment can be raised and lowered safely and stably. A mounting hole and two holes are provided on the surface of the movable plate 471. The mounting hole is fixedly connected to the outer wall of the ball nut 43, and the hole and the inner wall of the slider 472 are slidably connected to the outer wall of the guide column 44. The two sliders 472 are respectively slidably connected to the two guide columns 44 to ensure the stability of the object carrier 47 during the lifting process. A number of connecting rods 473 are respectively connected to the opposite ends of the movable plate 471 and the two sliders 472 to enhance the structural strength of the plug plate 474. The two plug plates 474 are integrally formed with the outer wall of the movable plate 471 and the slider 472 to lift and release the rental mechanical equipment.

[0033] The moving mechanism 5 is responsible for the flexible movement of the vehicle. One end of each mounting shell 51 is integrally formed with either side of the vehicle frame 1, ensuring structural stability. They can be closed around the mechanical equipment to be moved, forming an enclosure. The bottom of the mounting shell 51 is provided with a number of equally spaced hemispherical grooves 52 and threaded holes that match the locking bolts 56. The inner wall of each hemispherical groove 52 is embedded with a number of steel balls, which form a rolling connection with the moving ball 53, reducing frictional resistance during the rotation of the moving ball 53. The moving balls 53 are placed within the hemispherical grooves 52 and can roll freely within them, thus enabling flexible adjustment of the moving mechanism 5. The surfaces of the two base plates 54 are provided with a number of equally spaced limiting holes 55, which are used to accommodate and limit the range of movement of the moving balls 53. The inner ring of the limiting holes 55 is designed to be larger at the top and smaller at the bottom, tightly fitting the outer wall of the moving ball 53, ensuring that the moving ball 53 is stable within the limiting holes 55 and is not easily dislodged. The bottom ends of several locking bolts 56 are evenly spaced and extend through the two base plates 54. They are then threaded into the inner walls of threaded holes provided at the bottom end of the mounting shell 51. By adjusting the tightening degree of the locking bolts 56, the relative position between the base plates 54 and the mounting shell 51 can be fine-tuned, thereby adjusting the position of the moving ball 53 within the limiting hole 55, thereby achieving flexible adjustment of the moving mechanism 5.

[0034] The stabilizing mechanism 6 is responsible for stabilizing the mechanical equipment lifted by the lifting mechanism 4. Two sets of telescopic motors 61 are fixedly mounted inside the two mounting shells 51. The telescopic motors 61 should be selected to meet the requirements of the working environment, providing sufficient thrust, speed, and stability. When the telescopic motors 61 are activated, their telescopic ends can move outward or inward, thereby driving the connected clamps 62 to move. The clamps 62 are another key component of the stabilizing mechanism 6. The two clamps 62 are located at opposite ends of the two mounting shells 51 and are fixedly connected to the telescopic ends of the telescopic motors 61. When the telescopic motors 61 are operating, the clamps 62 move with the movement of the telescopic ends, thereby clamping or loosening the mechanical equipment. To enhance the clamping effect of the clamps 62 and prevent damage to the mechanical equipment, the inner walls of the clamps 62 are equipped with rubber pads. These rubber pads not only have good elasticity to accommodate mechanical equipment of different shapes and sizes, but also effectively reduce friction and vibration between the clamps 62 and the mechanical equipment, improving overall stability and durability. In addition, the outward protruding design of the rubber pad can further increase its contact area with the mechanical equipment and improve the clamping effect.

[0035] The operating principle of this equipment rental dolly is as follows: To move the mechanical equipment to be rented, the user moves the dolly so that the two insert plates 474 are inserted into the bottom of the mechanical equipment. By activating the drive motor 41, its output drives the ball screw 42 through a coupling to rotate. The rotational motion of the ball screw 42 is converted into linear motion of the ball nut 43, which moves up and down along the ball screw 42. Simultaneously, the object carrier 47 is fixedly connected to the ball nut 43 via the movable plate 471. The slider 472 slides on the guide post 44, ensuring the smooth raising and lowering of the object carrier 47, thereby lifting the mechanical equipment. Then, by activating the two telescopic motors 61, their telescopic ends move outward, driving the clamping plates 62 toward the mechanical equipment. When the clamping plates 62 come into contact with the mechanical equipment, the rubber pads provide cushioning and protection. As the telescopic motors 61 continue to operate, the clamping plates 62 gradually tighten the mechanical equipment until the desired stability is achieved. The rotation of several movable balls 53 mounted on the bottom of the mounting housing 51 enables the flexible movement of the equipment.

[0036] It should be noted that the specific models and specifications of the battery 2, drive motor 41, and telescopic motor 61 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principles of the battery 2, the drive motor 41, and the telescopic motor 61 are clear to those skilled in the art and will not be described in detail here.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present application is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein.
