[0004] To solve the above-mentioned technical problems, the purpose of this utility model is achieved as follows: This utility model relates to a high-load mobile unit, including a frame, which includes a floor plate and a roof plate. Side plates arranged symmetrically on both sides are provided between the roof plate and the floor plate. A driven axle and a driving axle are rotatably connected to the side plates. Wheels are respectively provided at both ends of the driving axle and the driven axle. A platform is provided above the roof plate. A guide rod and a suspension rod extending vertically are slidably connected to the roof plate. The upper ends of the suspension rod and the guide rod are both connected to the platform. A suspension body is provided at the lower end of the suspension rod, located between the floor plate and the roof plate. The suspension body includes a suspension top plate and a suspension side plate. A high-torque gear located above the drive wheel axle and a low-torque gear located below the drive wheel axle are rotatably connected to the suspension side plate. The drive wheel axle is provided with a first gear that meshes with the low-torque gear or the high-torque gear. A motor is fixedly connected to the vehicle side plate. The output shaft of the motor is provided with a second gear that meshes with the low-torque gear or the high-torque gear. The suspension side plate has a first clearance hole for the drive wheel axle to move up and down and a second clearance hole for the output shaft of the motor to move up and down. A limiting component is provided between the guide rod and the vehicle side plate to restrict the guide rod from sliding up and down.

[0005] The present invention is further configured such that: the limiting component includes a limiting spring piece connected to the side panel of the vehicle at one end, a fixed limiting protrusion is provided at the end of the limiting spring piece facing the guide rod, and the guide rod is provided with an upper movable limiting groove and a lower movable limiting groove that match the fixed limiting protrusion;

[0006] When the fixed limiting protrusion is embedded in the upper movable limiting groove, the platform is in a low position, and both the first gear and the second gear mesh with the high torque gear; when the fixed limiting protrusion is embedded in the lower movable limiting groove, the platform is in a high position, and both the first gear and the second gear mesh with the low torque gear.

However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0014] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See Figure 1 and Figure 2As shown, the high-load mobile unit involved in this embodiment includes a frame, which includes a floor plate 1 and a roof plate 2. Side plates 3 are symmetrically arranged between the roof plate 2 and the floor plate 1. Driven wheel axles 4 and driving wheel axles 5 are rotatably connected to the side plates 3. Wheels 6 are respectively provided at both ends of the driving wheel axle 5 and the driven wheel axle 4. A platform 7 is provided above the roof plate 2. A guide rod 8 and a suspension rod 9 extending vertically are slidably connected to the roof plate 2. The upper ends of both the suspension rod 9 and the guide rod 8 are connected to the platform 7. A suspension body is provided at the lower end of the suspension rod 9, located between the floor plate 1 and the roof plate 2. The suspension body includes a suspension top plate 10 and suspension side plates 1. 1. A high-torque gear 12 and a low-torque gear 13 located above the drive wheel axle are rotatably connected to the suspension side plate 11. The drive wheel axle 5 is provided with a first gear 14 that meshes with the low-torque gear or the high-torque gear. A motor (not shown) is fixedly connected to the vehicle side plate 3. The output shaft of the motor is provided with a second gear 15 that meshes with the low-torque gear or the high-torque gear. The suspension side plate 11 is provided with a first clearance hole 16 for the drive wheel axle to move up and down and a second clearance hole 17 for the output shaft of the motor to move up and down. A limiting component is provided between the guide rod 8 and the vehicle side plate 3 to limit the guide rod from sliding up and down.

[0017] Furthermore, the limiting component includes a limiting spring 18 connected to the side panel 3 at one end, and a fixed limiting protrusion 19 is provided at the end of the limiting spring 18 facing the guide rod. The guide rod 8 is provided with an upper movable limiting groove 20 and a lower movable limiting groove 21 that match the fixed limiting protrusion.

[0018] When the fixed limiting protrusion 19 is embedded in the upper movable limiting groove 20, the platform 7 is in a low position, and the first gear 14 and the second gear 15 are both engaged with the high torque gear 12; when the fixed limiting protrusion 19 is embedded in the lower movable limiting groove 21, the platform 7 is in a high position, and the first gear 14 and the second gear 15 are both engaged with the low torque gear 13.

[0019] Furthermore, the guide rods 8 are arranged in a 2x2 rectangular array on the roof panel 2.

[0020] In this embodiment, when the load on the platform 7 is too heavy to move it downwards, the fixed limiting protrusion 19 is embedded in the lower movable limiting groove 21. At this time, the platform 7 is in a high position, and both the first gear 14 and the second gear 15 mesh with the low torque gear 13, resulting in fast transmission speed, low torque, and fast movement of the moving unit. When the load on the platform 7 is heavy and needs to move it downwards, the fixed limiting protrusion 19 is embedded in the upper movable limiting groove 20, and the platform 7 is in a low position. At this time, both the first gear 14 and the second gear 15 mesh with the high torque gear 12, resulting in slow transmission speed, high torque, and slow movement of the moving unit.

[0021] The guide rod 8 is used to guide the platform 7 as it moves up and down relative to the frame.

[0022] The combination of the limiting spring 18, the fixed limiting protrusion 19, the upper movable limiting groove 20 and the lower movable limiting groove 21 is used to axially position the guide rod 8 when it moves up and down.

[0023] Among them, the suspension rod 9 is used to transmit force and realize the linkage between the suspension body and the platform 7.

[0024] Example 2

[0025] See Figure 1 and Figure 2 As shown, the high-load moving unit involved in this embodiment is further configured, based on embodiment 1, with a guide sleeve 22 that is fixed to the roof panel slidably connected to the guide rod 8.

[0026] In this embodiment, the guide sleeve 22 is used to guide the guide rod 8 as it moves up and down relative to the roof panel 2.

[0027] Example 3

[0028] See Figure 1 and Figure 2 As shown, the high-load moving unit involved in this embodiment is further configured, based on embodiment 1, with a shock-absorbing pad 23 provided on the top of the platform 7.

[0029] In this embodiment, the shock-absorbing pad 23 is used as a buffer to absorb shocks.

[0030] The high-load moving unit involved in this utility model can switch the motor output torque when the load increases to the point that the platform moves downward, so as to drive the trolley to move by using high torque. It can also achieve low torque and fast movement by manually resetting the platform. The dual torque switching output is flexible and convenient to use, with complete overall functions and strong practicality.
