Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides an auxiliary power device. Figure 1 This diagram shows a three-dimensional structural schematic of the auxiliary power device of the first structure in an embodiment of the present invention. Figure 2An exploded structural diagram of the auxiliary power device of the first structure in an embodiment of this utility model is shown. The auxiliary power device includes a base plate 100, an electric lifting mechanism 200, an operating mechanism 300, a support frame 400, and an electric drive wheel mechanism 500. A main rotating shaft 110 is rotatably disposed in the base plate 100, and the main rotating shaft 110 vertically penetrates the base plate 100. The electric lifting mechanism 200 is mounted on the upper end of the main rotating shaft 110 based on a connecting plate 210. The electric drive wheel mechanism 500 is mounted on the lower end of the main rotating shaft 110. The operating mechanism 300 is mounted on one side of the connecting plate 210. The operating mechanism 300 is subjected to external... The force causes the connecting plate 210, the electric lifting mechanism 200, the main rotating shaft 110, and the electric drive wheel mechanism 500 to rotate synchronously horizontally. The electric lifting mechanism 200 and the electric drive wheel mechanism 500 are started or stopped by the operating mechanism 300. The upper side of the support frame 400 is connected to the output end of the electric lifting mechanism 200 based on the extension frame 401, and the lower side of the support frame 400 is hinged to the base plate 100 based on the connecting rod 402. The support frame 400 is raised or lowered by the electric lifting mechanism 200. At least two equipment connection parts 403 are provided on the support frame 400.

[0020] The auxiliary power device of this utility model integrates the operating mechanism 300, the electric lifting mechanism 200, the electric drive wheel mechanism 500, and the support frame 400 together. It can be conveniently installed on equipment with casters in an additional form through the support frame 400. Using the original casters of the equipment as driven support, the electric drive wheel mechanism 500 provides active driving force, the electric lifting mechanism 200 provides lifting force, and the operating mechanism 300 provides steering force. It can effectively overcome problems such as large starting inertia, difficult steering, and difficulty in pushing or pulling on slight slopes or uneven surfaces, and together realize the easy movement of heavy equipment, so that even a single person can easily move heavy equipment with casters.

[0021] The auxiliary power device of this utility model provides active driving force through the electric drive wheel mechanism 500, which overcomes the huge static friction resistance and rolling resistance of the casters of heavy equipment during startup and operation. It can move easily even on slight slopes or uneven roads, allowing one operator to easily move equipment weighing hundreds of kilograms or even more. This replaces the multi-person collaborative operation required in the traditional method (relying solely on manpower), which not only improves work efficiency but also eliminates safety hazards caused by uneven force exerted by multiple people.

[0022] The auxiliary power device of this utility model is rigidly connected to the equipment body through a liftable support frame 400 and equipment connection part 403 (such as bolt holes). It does not replace or suspend the original casters of the equipment, but uses the original casters of the equipment as driven support. This collaborative design of "active drive + driven casters" makes the device a universal power module that can be quickly installed on most heavy equipment with casters. There is no need to purchase or use large, special handling equipment (such as forklifts), and it is applicable to a wide range of scenarios.

[0023] The auxiliary power device of this utility model mechanically links the operating mechanism 300, the electric lifting mechanism 200 and the electric drive wheel mechanism 500 through the main rotating shaft 110; the operator can intuitively control the propulsion (or pulling) direction of the entire device through a single operating mechanism 300, realizing integrated synchronous control of power, steering and lifting, which is flexible and convenient, and is especially suitable for precise displacement in narrow spaces.

[0024] The auxiliary power device of this utility model, through the cooperation of the electric lifting mechanism 200 and the support frame 400, can appropriately raise the front end of the equipment before starting the electric drive wheel mechanism 500, transferring part of the weight of the equipment and load to the solid base plate 100 and the electric drive wheel mechanism 500 of this device. This can effectively reduce the pressure on the original casters of the equipment, reduce their steering resistance, and also increase the adhesion between the electric drive wheel mechanism 500 and the ground, making starting and running more stable and effortless, and avoiding slippage.

[0025] In some specific embodiments, the electric lifting mechanism 200 is an electro-hydraulic mechanism or an electric push rod mechanism. Both electro-hydraulic and electric push rod mechanisms are existing, mature components that can provide powerful lifting force. Preferably, the electric lifting mechanism 200 is an electro-hydraulic mechanism; this type of mechanism has been widely used and verified in industrial handling equipment such as electric forklifts. It is a technologically mature and reliable linear actuator. Its core advantage lies in its ability to provide extremely powerful thrust and excellent self-locking performance. After lifting heavy objects, it can stably maintain its position without continuous power supply, ensuring safety and reliability.

[0026] In some specific embodiments, please refer to Figure 1 and Figure 2The operating mechanism 300 includes a mounting base 310, a joystick 320, and a control box 330. The mounting base 310 is fixedly mounted on one side of the connecting plate 210. The lower end of the joystick 320 is hinged to the mounting base 310, and the upper end of the joystick 320 is provided with a handle 321. The control box 330 is fixedly mounted on the main body of the joystick 320. The control box 330 contains a battery module and a control circuit board. The battery module and the control circuit board are electrically connected. The control circuit board is electrically connected to the electric lifting mechanism 200 and the electric drive wheel mechanism 500, respectively.

[0027] Operators can naturally apply horizontal force in any direction by holding the handle 321 with one or both hands. This force is transmitted to the main shaft 110 through the joystick 320, mounting base 310, and connecting plate 210, thereby directly and intuitively controlling the movement direction of the electric drive wheel mechanism 500 and achieving precise directional control. Meanwhile, the control box 330 integrated on the joystick 320 is rationally laid out, with its human-machine interface (such as the power switch, lifting button, and speed control knob) located within easy reach. Operators do not need to leave their operating position or search for external control units; they can complete all operations—forward / backward, acceleration / deceleration, and equipment lifting / lowering—with one hand while moving, greatly improving operational convenience and safety.

[0028] Specifically, Figure 3 A schematic diagram of the connection structure between the mounting base and the control lever in an embodiment of the present invention is shown. The mounting base 310 is provided with an elastic buffer 311, which is located on the side away from the electric lifting mechanism 200. The lower end of the control lever 320 is rotatably provided with a first rotating shaft 322, the axis of which is perpendicular to the length direction of the control lever 320. The first rotating shaft 322 is hinged to the top end of the elastic buffer 311 based on the support rod 3221.

[0029] When the operator releases the control lever 320, the elastic buffer 311 (which can be a compression spring, polyurethane buffer block, etc.) releases its stored elastic potential energy, pushing the control lever 320 automatically back to its vertical neutral position via the support rod 3221. This effectively prevents the control lever 320 from swinging arbitrarily due to inertia or equipment vibration, improving the standardization and safety of the equipment. Furthermore, the elastic buffer 311 absorbs impact vibrations from uneven ground or during start-up / stop, preventing these vibrations from being directly transmitted to the operator's hand, thus improving the smoothness and comfort of operation.

[0030] In some specific embodiments, please refer to Figure 2The electric drive wheel mechanism 500 includes a drive motor 510, a second rotating shaft 520, and two rollers 530. The drive motor 510 is fixedly connected to the main rotating shaft 110. The second rotating shaft 520 is rotatably disposed in the main rotating shaft 110 and is perpendicular to the main rotating shaft 110. The two rollers 530 are respectively fixedly disposed at both ends of the second rotating shaft 520. The output end of the drive motor 510 is connected to the second rotating shaft 520 based on a transmission assembly.

[0031] The electric drive wheel mechanism 500 forms an extremely compact and highly integrated power output unit by fixing the drive motor 510 to the main shaft 110 and embedding the second shaft 520, which carries the double rollers 530, inside the main shaft 110. Its function is to efficiently convert the rotational power of the drive motor 510 into the driving force for the equipment's movement, and to mechanically synchronize it with the steering system. On the one hand, it greatly saves bottom installation space, allowing the electric drive wheel mechanism 500 to be adapted to various low-profile equipment; on the other hand, it ensures that the drive wheel assembly can function as a rigid, integral unit, achieving precise, synchronized steering within milliseconds according to operating commands, ultimately providing heavy equipment with stable, powerful, and intuitive active movement capabilities.

[0032] Specifically, the transmission component can be a gearbox or a synchronous belt pulley mechanism, which has high transmission efficiency.

[0033] Figure 4 This shows a side view of the auxiliary power device of the second structure in an embodiment of the present invention. Figure 5 A three-dimensional structural diagram of the auxiliary power device in the second structure of this utility model embodiment is shown. The bottom of the connecting plate 210 or the bottom of the operating mechanism 300 is connected to a movable caster 620 based on the connecting frame 610. The core function of the movable caster 620 is to act as an auxiliary driven support point, forming a stable three-point support structure with the electric drive wheel mechanism 500 (two rollers 530). On the one hand, this allows the auxiliary power device to stand independently without manual support, facilitating its connection to the target equipment. On the other hand, the movable caster 620 shares the load, thereby significantly reducing the bending moment and torque acting on the main shaft 110, which is beneficial to improving the service life and reliability of the main shaft 110.

[0034] For further details, please refer to Figure 4 and Figure 5 The extension frame 401 is equipped with a counterweight 404. The counterweight 404 can adjust the center of gravity distribution of the auxiliary power device and balance the weight of the operating mechanism 300, so that the auxiliary power device does not exhibit a "front-heavy" tendency when standing independently (with the electric drive wheel mechanism 500 and the movable caster 620 on the ground), further improving the standing stability of the auxiliary power device.

[0035] In some specific embodiments, please refer to Figure 5 A quick-connector 700 is installed on any of the device connection portions 403; Figure 6 An exploded view of the quick-connect component in an embodiment of the present invention is shown. The quick-connect component 700 includes a female quick-connect connector 710 and a male quick-connect connector 720. The female quick-connect connector 710 is fixedly disposed on the device connection part 403. One end of the male quick-connect connector 720 is inserted into the female quick-connect connector 710, and the other end of the male quick-connect connector 720 is fixedly connected to the target device. A quick-connect pin 730 is provided on the female quick-connect connector 710, and the quick-connect pin 730 passes through the male quick-connect connector 720 inserted into the female quick-connect connector 710. An anti-detachment pin 740 is provided at the end of the quick-connect pin 730.

[0036] When connecting the auxiliary power unit to the target equipment, the quick-connect male connector 720 is first pre-installed securely on the reserved interface or sturdy structural position of the target equipment using bolts. Then, the electric lifting mechanism 200 is operated to drive the support frame 400 to rise or fall, so that the quick-connect female connector 710 installed on the support frame 400 is precisely fitted onto the male connector. Finally, the quick-connect male connector 720 and quick-connect female connector 710 are locked together by the quick-connect pin 730, and an anti-disengagement pin 740 (such as an R-type pin) is inserted into the end of the quick-connect pin 730 to achieve rigid interlocking between the quick-connect male connector 720 and quick-connect female connector 710, thus completing the entire connection process.

[0037] The equipment connection section 403 adopts a quick-connect mode using a quick-connect male connector 720 and a quick-connect female connector 710, enabling rapid deployment and separation of the auxiliary power unit. This transforms the most time-consuming bolt tightening work into a pre-completed, one-time operation. Subsequent uses are simplified to a simple "align-lift / lower-lock" process, reducing connection time from tens of minutes to several minutes, significantly improving the turnaround efficiency of the auxiliary power unit. Furthermore, the quick-connect male and female connectors are specifically optimized for heavy-duty conditions. The rigid connection formed after locking is comparable to, or even stronger than, traditional bolt connections, effectively transmitting thrust and torque to ensure undamaged power delivery to the target equipment.

[0038] For further details, please refer to Figure 6The quick-connect female connector 710 is equipped with a hand-tightening fastener 750, the end of which extends into the quick-connect female connector 710 and abuts against the quick-connect male connector 720. This eliminates the assembly gap between the quick-connect male connector 720 and the quick-connect female connector 710, ensuring a tight connection between them as a whole. This effectively prevents impact noise and structural loosening caused by gaps during equipment start-up, shutdown, or impacts, ensuring pure and rigid power transmission. Furthermore, this design provides the entire connection structure with a certain tolerance compensation capability. For quick-connect male connectors 720 from different batches or with slight wear, the operator can adjust the screw-in depth of the hand-tightening fastener 750 to achieve the same tight connection effect. This reduces the extreme requirements for the machining precision of all parts, improving the versatility and service life of the quick-connect structure.

[0039] Figure 7 A schematic diagram of the connection structure between the support frame and the substrate in an embodiment of the present invention is shown. The support frame 400 includes two vertical rods 410, and a first horizontal rod 420 and a second horizontal rod 430 fixedly disposed on the two vertical rods 410. The first horizontal rod 420 is located above the second horizontal rod 430. The extension frame 401 is fixedly disposed on the middle part of the first horizontal rod 420. The device connection part 403 is located on both ends of the first horizontal rod 420. The lower end of any of the vertical rods 410 is hinged to the substrate 100 based on a connecting rod 402.

[0040] The core lifting force input from the extension frame 401 is directly transmitted to the equipment connection parts 403 located at both ends of the first crossbar 420, thereby acting evenly on the target equipment. At the same time, the horizontal component force and torsional load generated during the lifting process are effectively guided to the base plate 100 by the two vertical bars 410 and the hinged connecting rods 402 at their lower ends. This design creates a stable and efficient statically determinate structure, avoids local stress concentration, and ensures structural integrity under heavy loads.

[0041] Furthermore, by placing the equipment connection part 403 on the outermost side of the support frame 400 (at both ends of the first crossbar 420), the maximum support span is achieved; this provides excellent lateral stability for the lifted equipment and effectively prevents the equipment from swaying or overturning during movement; the entire frame evenly distributes the load of the equipment onto the two vertical bars 410 and the connecting rod 402, making the device more balanced in terms of force.

[0042] Furthermore, the lower ends of the two vertical rods 410 are hinged to the base plate 100 via connecting rods 402, forming a stable lifting mechanism together with the electric lifting mechanism 200 above. This ensures that the support frame 400 and the equipment on it only make strict vertical translation movements during the lifting and lowering process, without tilting forward or backward or getting stuck, which greatly improves the safety and controllability of the operation.

[0043] Furthermore, the frame structure of this support frame 400 ensures extremely high structural rigidity and strength while avoiding material waste through reasonable mechanical design; compared with solid plates or bulky integral welded structures, this design achieves a balance between lightweight and high strength, reducing manufacturing costs and device weight.

[0044] The working process of the auxiliary power device of this utility model is as follows: First, connect the support frame 400 and the target equipment with casters directly with bolts, or connect the support frame 400 and the target equipment with casters with quick-connect fittings 700. Then, control the electric lifting mechanism 200 through the operating mechanism 300 to drive the support frame 400 to appropriately raise the front end of the target equipment (the front end of the target equipment can be completely lifted off the ground). Next, control the electric drive wheel mechanism 500 and the direction of movement through the operating mechanism 300 to easily move the target equipment. Finally, after moving the target equipment to the preset position, control the electric lifting mechanism 200 through the operating mechanism 300 to lower the front end of the target equipment through the support frame 400, and then separate the support frame 400 and the target equipment.

[0045] The auxiliary power device of this utility model integrates the operating mechanism 300, the electric lifting mechanism 200, the electric drive wheel mechanism 500, and the support frame 400 together. It can be conveniently installed on equipment with casters in an additional form through the support frame 400. Using the original casters of the equipment as driven support, the electric drive wheel mechanism 500 provides active driving force, the electric lifting mechanism 200 provides lifting force, and the operating mechanism 300 provides steering force. It can effectively overcome problems such as large starting inertia, difficult steering, and difficulty in pushing or pulling on slight slopes or uneven surfaces, and together realize the easy movement of heavy equipment, so that even a single person can easily move heavy equipment with casters.

[0046] The control mechanism 300 includes a mounting base 310, a joystick 320, and a control box 330, integrating power, control, and operation. It allows for direct and intuitive control of the electric drive wheel mechanism 500's movement direction, achieving precise directional control. Meanwhile, the control box 330, integrated on the joystick 320, is rationally laid out, with its human-machine interface (such as the power switch, lifting button, and speed control knob) placed within easy reach. The operator can perform all operations—forward / backward, acceleration / deceleration, and equipment lifting / lowering—with one hand while walking, greatly improving operational convenience and safety. Furthermore, the joystick 320 and mounting base 310 are connected by an elastic buffer 311, which allows for automatic reset of the joystick 320 and improves operational stability and comfort.

[0047] The electric drive wheel mechanism 500 includes a drive motor 510, a second rotating shaft 520, and two rollers 530, forming an extremely compact and highly integrated power output unit that can efficiently convert the rotational power of the drive motor 510 into the moving driving force of the equipment and mechanically synchronize with the steering system.

[0048] The bottom of the connecting plate 210 or the bottom of the operating mechanism 300 is connected to the connecting frame 610 and equipped with movable casters 620, which act as an auxiliary driven support point. They can form a stable three-point support structure with the electric drive wheel mechanism 500 (two rollers 530), which not only allows the whole structure to stand independently, but also improves the stress on the structure and helps to extend the service life of key components. Moreover, by setting a counterweight 404 on the extension frame 401, the weight of the operating mechanism 300 can be balanced to prevent the front from being heavier than the back, further improving the stability of the auxiliary power device.

[0049] The equipment connection part 403 can adopt a quick connection mode with quick-connect male connector 720 and quick-connect female connector 710, which realizes the rapid deployment and separation of the auxiliary power unit.

[0050] Among them, the support frame 400 is not a simple combination of rods, but an optimized structure that has undergone careful mechanical calculations. It ensures that the huge load from heavy equipment can be transmitted and distributed smoothly, efficiently and safely. It is the core basic structure that enables the entire auxiliary power unit to reliably support and move heavy equipment.

[0051] The above provides a detailed description of an auxiliary power device provided by the embodiments of this utility model. Specific examples have been used to illustrate the principle and implementation of this utility model. The description of the above embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
