In this solution, electric hoists are used as an example. As a type of lightweight lifting equipment, electric hoists are widely used in various industrial applications due to their ease of operation and strong adaptability.

[0003] Existing electric hoists are typically driven by asynchronous induction motors, which usually require an additional AC power supply. The external battery is typically separate from the main unit and needs to be connected via wiring. This results in bulky equipment, limited flexibility, inconvenient installation and maintenance, and the wiring is susceptible to environmental influences, posing safety hazards.

[0030] It should be noted that the block diagrams shown in the attached figures are merely functional entities and do not necessarily correspond to physically independent entities.

[0031] This disclosure provides a lifting device; a schematic diagram of the overall lifting device can be found here. Figure 1 and Figure 2 , Figure 1 This is an overall schematic diagram of the lifting equipment in an embodiment of this disclosure. Figure 2 This is a side view of the lifting equipment according to an embodiment of this disclosure. For the internal structure of the lifting equipment, see [link to relevant documentation]. Figure 3 , Figure 3 This is a cross-sectional view of the lifting device according to an embodiment of the present disclosure. The lifting device includes a main body 1, which includes a cavity 11 and a shell 12. The shell 12 covers the outside of the cavity 11. A battery 13, a drive mechanism, a drum 124, and a rope 114 are disposed inside the cavity 11. The battery 13 is electrically connected to the drive mechanism, and the output end of the drive mechanism is connected to the drum 124. One end of the rope 114 is fixed to the drum 124, and the other end of the rope 114 is connected to the object to be lifted. The length of the rope 114 wound on the drum 124 controls the lifting or lowering of the object to be lifted. The battery 13 provides electrical energy to the drive mechanism, which drives the rotation of the drum 124 to move the rope, thereby controlling the lifting or lowering of the object to be lifted.

[0032] Specifically, in this solution, the lifting equipment can be, for example, an electric hoist, which mainly consists of a main body 1, which includes two parts: an outer shell 12 and a cavity 11. The outer shell 12 protects the internal components; it covers the outside of the cavity 11, providing physical protection for the sensitive internal parts and preventing damage from the external environment. The cavity 11 is an internal space used to house the core components of the electric hoist.

[0033] Inside the cavity 11 are key components such as the battery 13, drive mechanism, drum 124, and rope 114. The battery 13 is the energy source, responsible for providing the necessary electrical energy to the drive mechanism. The drive mechanism typically includes a motor and a reducer, which convert the electrical energy provided by the battery into mechanical energy to drive the drum 124 to rotate. The drum 124 is the component that winds the rope. One end of the rope 114 is fixed to the drum 124, and the other end is connected to the object that needs to be lifted or lowered.

[0034] By controlling the winding length of the rope 114 on the drum 124, the vertical movement of the object to be lifted can be precisely controlled. As the drum 124 rotates, the rope 114 moves accordingly, causing the object to rise or fall. This design allows the operator to precisely raise or lower the load by controlling the rotation of the drum 124, achieving precise control over heavy objects.

[0035] This solution achieves its purpose by powering the drive mechanism with battery 13, which in turn drives the drum 124 to rotate. The rotation of the drum 124 transmits power through the rope 114, causing the object to be lifted to move vertically. This integrated design not only improves the space utilization efficiency of the electric hoist but also enhances its portability and flexibility, allowing the lifting equipment to be used in environments without a fixed power source, such as outdoor operations or mobile workplaces. Furthermore, the built-in battery design helps reduce the use of electrical wires, lowers the risk of wire wear and failure, and improves operational safety.

[0036] Regarding battery 13, it should be noted that it typically consists of multiple battery cells connected in series or parallel to meet the voltage and current requirements of the lifting equipment. Furthermore, the battery may include a battery management system 123 (BMS) for monitoring battery status, such as voltage, current, and temperature, as well as performing battery equalization, fault detection, and protection to ensure safe and efficient battery operation. This design allows the lifting equipment to operate independently without an external power source, improving its flexibility and portability. The integrated battery design also makes the lifting equipment more suitable for outdoor use or in locations where power access is difficult. In addition, the use of batteries helps reduce dependence on traditional energy sources, lowering energy consumption and operating costs, aligning with environmental protection and sustainable development trends. This design enables the lifting equipment to operate without a fixed power source, increasing its applicability in various environments, especially in outdoor or remote work areas where power access is inconvenient. Furthermore, the built-in battery design helps reduce dependence on external power sources, lower energy consumption, and improve energy efficiency, while also providing significant advantages in terms of mobility and ease of operation for the lifting equipment. In summary, the feature of installing batteries inside the cavity not only enhances the autonomy and flexibility of the lifting equipment, but also helps to improve its adaptability and work efficiency in diverse operating environments.

[0037] By integrating key components such as the battery, drive mechanism, drum, and rope into a single cavity and protecting it with an outer shell, a compact, efficient, and functionally integrated lifting device is achieved. Specifically, integrating the external battery into a single cavity of the main body not only optimizes the device's spatial layout and reduces the need for external wiring and connectors, thus simplifying installation and use in complex environments, but also directly powers the drive mechanism via the built-in battery, improving energy efficiency and response speed. Furthermore, since the drive mechanism is directly connected to the drum, it ensures precise and reliable power transmission, allowing the rope to wind and release smoothly and efficiently, precisely controlling the lifting or lowering of the object being pulled. Additionally, the integrated battery design helps protect the battery from external environmental factors such as dust, moisture, or physical damage, extending battery life and reducing maintenance costs. This design also enhances the lifting device's portability and flexibility, making it more suitable for use in environments without a fixed power source, such as outdoor operations or mobile applications. Moreover, the built-in battery provides a safer and more reliable energy supply, reducing safety risks caused by damaged wiring or poor connections. In summary, this solution not only improves the performance and reliability of the lifting equipment, but also enhances its adaptability and ease of maintenance, making it more suitable for diverse operating environments, while also providing users with a safer and more efficient user experience.

[0038] In some alternative implementations, the drive mechanism includes a permanent magnet motor 111 and a rotary vector reducer 113, the permanent magnet motor 111 being connected to the rotary vector reducer 113 via a motor shaft 1111, and the output shaft of the rotary vector reducer 113 being connected to a drum 124.

[0039] Specifically, the drive mechanism is the core component of the lifting equipment, responsible for converting electrical energy into mechanical energy to drive the winding and release of the rope 114, thereby lifting and lowering the load. This drive mechanism includes a permanent magnet motor 111 and a rotary vector reducer 113. The permanent magnet motor 111 is a motor that uses permanent magnets to generate a magnetic field, featuring high efficiency, high power density, and excellent control performance, providing stable and powerful power output. The permanent magnet motor 111 is connected to the rotary vector reducer 113 via a motor shaft 1111. The rotary vector reducer 113 receives the rotational motion from the motor shaft 1111 and converts it into a low-speed, high-torque output more suitable for driving the drum 124.

[0040] It should be noted that the rotary vector reducer 113, also known as an RV reducer, is a high-precision, high-torque-density speed reduction device. Its main function is to convert the high-speed, low-torque output of the motor into a low-speed, high-torque output to meet the torque requirements of the drum 124. Due to its internal structural design, this reducer can provide smooth and precise speed control, making it very suitable for applications requiring precise control.

[0041] In its implementation, the permanent magnet motor 111 is tightly connected to the rotary vector reducer 113 via the motor shaft 1111, ensuring efficient power transmission. The output shaft of the rotary vector reducer 113 is directly connected to the drum 124. Thus, when the permanent magnet motor 111 is working, power is transmitted to the drum through the RV reducer, driving the drum to rotate, thereby enabling the winding and unwinding of the rope 114 and controlling the lifting or lowering of the load. This design not only improves the operating efficiency and precision of the lifting equipment but also enhances its reliability and durability due to its compact structure and ease of maintenance, making it more suitable for diverse industrial applications.

[0042] Thus, by integrating a permanent magnet motor and a rotary vector reducer, a compact and efficient power transmission system is formed. The high efficiency and excellent control performance of the permanent magnet motor, along with the precise deceleration and torque enhancement of the rotary vector reducer, jointly ensure the smoothness and reliability of power output. This integrated design not only reduces energy loss and improves energy utilization efficiency but also makes the entire drive mechanism more compact, facilitating installation and maintenance. Furthermore, the output shaft of the rotary vector reducer is directly connected to the drum, ensuring the directness and accuracy of power transmission, thereby achieving precise control over the lifting or lowering of heavy objects. This design significantly improves the operational performance and safety of the electric hoist while reducing maintenance costs and complexity, making the equipment more suitable for various lifting operation environments.

[0043] In some alternative implementations, the lifting equipment also includes a brake device 115, which is disposed between the permanent magnet motor 111 and the rotary vector reducer 113 and connected to the drum 124 via the motor shaft 1111, for locking the drum 124 when the lifting equipment stops or is powered off.

[0044] Specifically, taking an electric hoist as an example, the lifting equipment includes a brake device 115, a safety mechanism used to prevent the load from accidentally slipping when the equipment stops working or a power outage occurs. In this design, the brake device 115 is cleverly positioned between the permanent magnet motor 111 and the rotary vector reducer 113. This arrangement allows the brake device 115 to directly apply braking force to the drum 124. It is understood that the brake device 115 is connected to the drum 124 via the motor shaft 1111, meaning that when the brake device 115 is activated, it can directly lock the rotation of the drum 124, preventing the drum 124 from rotating due to gravity, thus ensuring that the rope 114 does not slack and the load does not slip. The brake device 115 can provide necessary braking force at critical moments, avoiding possible accidents and damage. Therefore, this design not only improves the safety of the lifting equipment but also enhances its reliability. Furthermore, the integrated design of the brake device 115 also helps simplify the overall structure of the lifting equipment, making the equipment more compact and easier to install and maintain. In this way, the lifting equipment in this solution achieves stable load control in the event of a stop or power outage, ensuring operational safety and continuity of work.

[0045] Thus, the brake device equipped on this lifting equipment achieves a highly efficient safety locking mechanism through its strategic placement between the permanent magnet motor and the rotary vector reducer. Specifically, when the lifting equipment stops or experiences a power outage, the brake device responds quickly, applying braking force directly to the drum via the motor shaft to ensure immediate locking of the drum. This significantly improves equipment safety, effectively preventing load slippage due to gravity and thus avoiding potential accidents. Simultaneously, because the brake device provides immediate braking support at critical moments, ensuring operational continuity and precision, this design also enhances the equipment's stability and reliability. Furthermore, the integrated design of the brake device simplifies the overall structure of the lifting equipment, reduces maintenance costs, and improves maintenance efficiency, making the lifting equipment more suitable for lifting operation environments requiring high safety and efficiency.

[0046] In some alternative embodiments, see Figure 4 , Figure 4 This is a schematic diagram of the connector in an embodiment of this disclosure. A connector 116 is provided at the center of the output shaft of the rotary vector reducer 113. The connector 116 includes a fixing part 1161 and a connecting part 1162. The fixing part 1161 is used to fix one end of the rope 114, and the connecting part 1162 is engaged with the threaded hole at the output end of the rotary vector reducer 113.

[0047] In this embodiment, a special connector 116 is designed at the center of the output shaft of the rotary vector reducer 113 (RV reducer). This connector 116 consists of two parts: a fixing part 1161 and a connecting part 1162. The RV reducer is a high-precision speed reduction device that converts the high-speed, low-torque generated by the permanent magnet motor 111 into low-speed, high-torque to drive the drum 124 to rotate and achieve the winding and unwinding of the rope 114. The connector 116 is designed to ensure that the rope 114 can be securely connected to the output shaft of the reducer, thereby effectively transmitting power.

[0048] Regarding the two parts of the connector 116, the main function of the fixing part 1161 is to secure one end of the rope 114, ensuring that the rope 114 will not slip or loosen when transmitting power. This is crucial for ensuring the safety and reliability of the entire lifting system. The connecting part 1162 is designed with a thread that matches the threaded hole at the output end of the RV reducer. Through this threaded engagement, the connector 116 can be securely connected to the reducer output shaft, thus ensuring that the connector 116 will not rotate or shift when the rope 114 transmits power. With this design, one end of the rope 114 is fixed to the fixing part 1161 of the connector 116, while the connecting part 1162 of the connector 116 is tightly engaged with the threaded hole on the output shaft of the RV reducer, forming a stable and secure connection.

[0049] Thus, in this embodiment, the connector positioned at the center of the output shaft of the rotary vector reducer (RV reducer) achieves a stable connection between the rope and the reducer through the ingenious design of its fixing and connecting parts. This design not only improves the reliability of rope fixation, ensuring that the rope will not slip during lifting, thereby enhancing the safety of the entire lifting equipment, but also ensures the precise fit between the connecting part and the threaded hole at the output end of the reducer, guaranteeing the installation accuracy and firmness of the connector, making power transmission more efficient and reducing energy loss. Furthermore, this design simplifies the rope installation and maintenance process, as the threaded connection allows for quick and easy replacement or adjustment of the rope, reducing maintenance costs and time, and improving maintenance efficiency. In summary, this design improves the stability and reliability of the connection, optimizes power transmission efficiency, and simplifies maintenance work, thereby enhancing the overall performance and service life of the lifting equipment.

[0050] In some alternative embodiments, the fixing part 1161 is configured as a ring structure.

[0051] Specifically, "the fixing part 1161 is configured as a circular ring structure" means that the fixing part 1161 of the connector 116 adopts a circular ring design, which can provide uniform force distribution and reliable fixing effect. The circular ring structure fixing part 1161 contacts the rope 114 through its circular outer edge, ensuring that the rope 114 will not slip off the fixing point under high tension. This type of fixing part 1161 is usually connected to the rope 114 by bolts, screws or other fasteners to achieve a firm fixation.

[0052] In practical implementation, the fixing part 1161 of the ring structure can also have other specific design features, such as grooves, holes, or threads, to match the fittings (such as hooks, clamps, etc.) at the end of the rope 114 and ensure the stability of the connection. Furthermore, the fixing part 1161 of the ring structure may be made of high-strength materials, such as alloy steel or stainless steel, to withstand the high stress and wear generated during lifting operations. By designing the fixing part 1161 as a ring structure, the lifting equipment of this solution can ensure that one end of the rope 114 is safely and reliably fixed to the output shaft of the rotary vector reducer 113.

[0053] This design, employing a circular ring structure as the fixing unit, leverages its geometric advantages to evenly distribute rope tension, reduce wear, and enhance rope stability. Furthermore, the ring structure facilitates quick installation and disassembly, simplifying maintenance processes and reducing maintenance costs and downtime. Simultaneously, the ring's ability to easily connect to various rope end fittings also contributes to improved rope replacement efficiency. Moreover, the ring structure's simple shape and small size help maintain the overall compact design of the lifting equipment, making it lighter and easier to integrate into different lifting systems. In summary, the circular ring structure not only improves operational safety and reliability but also enhances the equipment's durability and economy.

[0054] In some alternative embodiments, see Figure 5 , Figure 5 This is a schematic diagram of the rope output position area in an embodiment of this disclosure. A first guide rail 117, a second guide rail 118, and a limiting part 119 are provided at the rope output position 1141. The first guide rail 117 and the second guide rail 118 are arranged parallel to each other. A first pulley 120 is provided on the first guide rail 117, and a second pulley 121 is provided on the second guide rail 118. The first pulley 120 and the second pulley 121 are within the limiting part 119, so that the first pulley 120 and the second pulley 121 move synchronously.

[0055] Specifically, the first guide rail 117 and the second guide rail 118 are two parallel tracks that provide stable guidance for the rope 114. A first pulley 120 and a second pulley 121 are respectively installed on these two guide rails. The function of these two pulleys is to guide the rope 114 along a predetermined path, ensuring the stability and accuracy of the rope 114 during output. The limiting part 119 is a key component located between the first pulley 120 and the second pulley 121. Its function is to ensure that the two pulleys can move synchronously, preventing them from sliding relative to each other on the guide rails, thereby avoiding twisting or tangling of the rope 114.

[0056] In practical implementation, when the lifting equipment is operating, the rope 114 passes through the groove between the first pulley 120 and the second pulley 121. Under the control of the limiting part 119, these two pulleys slide horizontally synchronously on the first guide rail 117 and the second guide rail 118. This synchronous motion design ensures the stability of the rope 114 during lifting or lowering, and also allows the rope 114 to be evenly distributed on the drum 124, thereby improving the lifting capacity of the lifting equipment and the service life of the rope 114. In addition, this design also helps to reduce friction and wear of the rope 114 during movement, improving the operating efficiency and reliability of the entire system.

[0057] In this way, the parallel arrangement of the first and second guide rails ensures the stable operation of the pulleys on the rails, while the limiting part ensures that the first and second pulleys move precisely and synchronously, avoiding possible rope deviation or twisting during movement. This synchronous movement mechanism not only improves the stability and accuracy of rope output but also helps reduce rope wear and extend its service life. Furthermore, this design helps to evenly distribute the rope tension on the drum, thereby improving the overall performance and safety of the lifting equipment. Through this innovative structural design, the lifting equipment can achieve smoother, more precise, and safer control when lifting and lowering heavy objects, significantly improving operational reliability and efficiency.

[0058] In some alternative embodiments, see Figure 6 , Figure 6 This is a front view of the lifting device in this embodiment of the present disclosure without the front cover. The lifting device also includes a cover 3, which is fixed to the outer casing 12 by a magnet 4.

[0059] Specifically, the design of the lifting equipment includes a component called a cover 3, which works in conjunction with the outer casing 12 to protect the internal components and maintain the integrity of the overall structure. The cover 3 can be a front cover, a side cover, or a rear cover, and its main function is to seal the interior of the lifting equipment, preventing dust, moisture, and other external substances from entering, thereby protecting the internal mechanical and electrical components.

[0060] In this design, the cover 3 and the outer shell 12 are fixed using magnets 4, an innovative fixing mechanism. The magnet 4 fixing method utilizes magnetic force to achieve a secure connection between the cover 3 and the outer shell 12, eliminating the need for traditional screws, bolts, or other mechanical fasteners. This magnetic fixing method not only simplifies the assembly process but also makes the disassembly and installation of the cover 3 more convenient and faster, facilitating maintenance and repair.

[0061] In the specific implementation of this solution, a ring of magnets 4 can be installed around the edge of the cover 3, attracting it to the ferrous or magnetic material on the outer shell 12 to form a tight closure. This magnetic fixing mechanism not only ensures the stability of the cover 3 during the operation of the lifting equipment, but also improves maintenance efficiency due to its tool-free quick opening and closing characteristic.

[0062] Thus, the cover design of the lifting equipment in this embodiment, secured by magnets, simplifies the installation and disassembly process, reduces maintenance difficulty, and, because it eliminates the need for traditional mechanical fasteners, reduces the risk of loosening due to vibration, thereby enhancing the stability and reliability of the equipment. Furthermore, the magnetic fixing method helps improve the sealing performance of the lifting equipment, more effectively preventing the intrusion of dust, moisture, and other contaminants, extending the service life of internal components. Simultaneously, this design reduces noise and vibration, improving operational comfort. The magnetic cover design also provides the lifting equipment with a more modern and aesthetically pleasing appearance, enhancing the overall quality of the product. In summary, this innovative cover fixing method improves the performance of the lifting equipment while also enhancing its ease of maintenance and durability.

[0063] In some optional embodiments, the lifting device further includes a guide section 2, which is connected to the main body 1 and is used to guide the main body 1 to slide on an external track; the guide section 2 is provided with a first anti-collision section 21 and a second anti-collision section 22 on both sides along the extension direction of the main body 1, and the distance between the first anti-collision section 21 and the second anti-collision section 22 is greater than the length of the main body 1 in the extension direction.

[0064] Specifically, in this design, the guide section 2 of the lifting equipment is a key component. It is connected to the main body 1 of the lifting equipment, and its main function is to ensure that the main body 1 can slide smoothly and accurately along the external track. This design allows the lifting equipment to move horizontally to the desired position during vertical lifting operations, thereby covering a wider working area. The guide section 2 is typically designed to include rollers or other types of sliding elements that contact the track, reducing friction and providing stable support.

[0065] Furthermore, the guide section 2 is provided with a first anti-collision section 21 and a second anti-collision section 22 on both sides along the extension direction of the main body 1. The anti-collision sections are structures specifically designed to absorb impact forces and prevent collisions; they can be buffers made of rubber, plastic, or other elastic materials. The distance between the first anti-collision section 21 and the second anti-collision section 22 is designed to be greater than the length of the main body 1 in the extension direction. This design ensures that when the lifting equipment moves to the end of the track, the anti-collision section can first contact the stop of the track, thereby preventing direct impact from the main body 1 and protecting the lifting equipment from damage. Through this design, the anti-collision section provides additional safety protection when the lifting equipment moves to the extreme position of the working area, reducing the risk of equipment damage due to accidental collisions.

[0066] In this way, the guide section ensures that the main body of the lifting equipment can slide smoothly along the external track, optimizing the equipment's mobility and enabling it to accurately reach the designated position to perform lifting tasks. Simultaneously, the design of the first and second anti-collision sections, especially the distance between them exceeding the length of the main body in the extending direction, provides effective cushioning and collision protection. This design allows the anti-collision sections to absorb impact when the lifting equipment moves to the end of the track, preventing the main body from directly impacting the track stops, thereby reducing the risk of equipment damage and extending its service life. Furthermore, this structure improves operational safety by preventing the lifting equipment from accidentally slipping off the track, reducing the risk of potential injury to operators or the surrounding environment. In summary, this feature not only enhances the operational flexibility and precision of the lifting equipment but also significantly improves its safety and reliability, making it more adaptable to diverse and demanding lifting operation environments.

[0067] In some alternative embodiments, a charging interface 14 is provided at the bottom of the housing 12, through which an external charging device can supply power to the battery 13.

[0068] Specifically, in this design, a charging interface 14 is specially provided at the bottom of the housing 12. This charging interface 14 is a key component for connecting an external charging device, allowing users to conveniently charge the battery 13 inside the cavity. The battery 13, as the main power source of the lifting equipment, is responsible for providing the necessary electrical energy to drive the motor and other electrical components.

[0069] In the specific implementation of this solution, when the lifting equipment's battery needs to be charged, the user can connect an external charging device to the lifting equipment through charging interface 14. Charging interface 14 can use a standard charging connector to ensure compatibility and ease of use. During charging, the external charging device transfers electrical energy to the battery, while the battery management system 123 (BMS) monitors the charging process to ensure the battery is safely and effectively fully charged, preventing overcharging, overheating, or other events that may damage the battery. The advantage of this design is that it provides a simple and direct charging method, allowing the lifting equipment to be conveniently charged even in locations far from power outlets.

[0070] This design allows users to directly charge the battery built into the cavity via an external charging device, eliminating the hassle of frequently removing and reinstalling the battery. This built-in charging interface not only improves the safety and efficiency of the charging process but also ensures that the lifting equipment can be quickly and conveniently replenished in various working environments, reducing equipment downtime and improving work efficiency. Furthermore, the built-in charging interface helps protect the battery from external environmental influences, extending its lifespan. Overall, this feature enhances the autonomous operation capability of the lifting equipment, making it more suitable for outdoor or hard-to-reach power supply environments, while also providing users with a more convenient and efficient charging solution.

[0071] In some optional embodiments, a control unit 15 is also provided in the cavity. The control unit 15 is located on the side of the battery 13 away from the drive mechanism and is used to interact with external devices.

[0072] Specifically, the control unit 15 typically includes electronic components such as a microprocessor, memory, and input / output interfaces. It uses built-in software to precisely control the actions of the lifting equipment, such as starting, stopping, accelerating, and decelerating. Furthermore, the control unit 15 is responsible for monitoring the operating status of the lifting equipment, including key parameters such as motor temperature, battery level, and rope tension 114, to ensure the safe and efficient operation of the equipment.

[0073] In practice, the control unit 15 interacts with external devices (such as remote controls, computer systems, or other industrial automation equipment) via wired or wireless means. This interaction allows operators to remotely program and monitor the lifting equipment, achieving more flexible and intelligent control. For example, operators can send commands via remote control to control the lifting and lowering movements of the lifting equipment, or use the computer system to diagnose faults and develop maintenance plans. By installing the control unit 15 within the cavity 11, this solution not only improves the convenience and flexibility of operation but also enhances the equipment's intelligence level, enabling it to better adapt to the needs of modern industrial automation.

[0074] In this way, the control unit, as the intelligent core of the lifting equipment, not only handles various control logics within the equipment but also achieves functions such as remote monitoring, fault diagnosis, and preventative maintenance through information interaction with external devices. This design allows the lifting equipment to be more flexibly integrated into existing industrial automation systems, improving the automation level and efficiency of the production line. Simultaneously, the intelligent characteristics of the control unit enhance equipment safety. Through real-time monitoring and data analysis, potential fault risks can be detected and addressed promptly, reducing unexpected downtime and improving operational continuity and reliability. Furthermore, the ability to interact with external devices provides the lifting equipment with more expansion possibilities, such as adding new functions or improving performance through software upgrades, thereby extending the equipment's lifespan and maintaining its technological advancement. In summary, the control unit within the cavity not only improves the ease of operation and intelligence of the lifting equipment but also enhances its adaptability, safety, and maintenance efficiency through effective interaction with external devices, making it more suitable for the needs of modern industrial automation.

[0075] In some alternative embodiments, see Figure 7 , Figure 7 This is a rear view of the lifting device in this embodiment of the present disclosure without the rear end cover. A controller 16 is also provided inside the cavity 11. The controller 16 is located on the side of the drive mechanism away from the battery 13, and the controller 16 is electrically connected to the control unit 15.

[0076] Specifically, a controller 16 is installed inside the cavity 11 of the lifting equipment. The controller 16 is an electronic device whose main function is to precisely adjust the speed and torque of the motor according to the instructions issued by the control unit 15, thereby achieving precise control of the lifting or lowering action of the lifting equipment.

[0077] In practice, the controller 16 and control unit 15 communicate via an electrical connection. The control unit 15 is the intelligent core of the lifting equipment, responsible for receiving operating commands, processing information, and generating control signals. These control signals are then sent to the controller 16, which adjusts the motor's operating state based on these signals, such as starting, stopping, accelerating, or decelerating. This design makes the motor's operation more flexible and responsive, while also improving the efficiency and reliability of the entire system. By placing the controller 16 on the side of the drive mechanism away from the battery 13, specifically closer to the permanent magnet motor, the length of the electrical connection is reduced, signal transmission delay is decreased, and the response speed of the control system is improved. Furthermore, this layout helps simplify wiring, reduce space occupation, and potentially improve the system's maintenance convenience. The close collaboration between the controller 16 and control unit 15 ensures that the lifting equipment can precisely control the winding and releasing of the rope 114 according to operational requirements, achieving smooth and precise lifting operations.

[0078] Thus, the controller, located within the cavity and positioned away from the battery on the drive mechanism, along with its electrical connection to the control unit, brings a series of beneficial effects. Specifically, this layout first ensures that the controller can quickly respond to commands from the control unit, achieving precise control of the permanent magnet motor and thus accurately adjusting the lifting and lowering movements of the hoisting equipment. Second, this design simplifies electrical connections, reduces signal transmission delays, and improves the overall system's response speed and operating efficiency. Furthermore, the compact layout helps reduce space occupation, making the hoisting equipment design more compact and facilitating maintenance and repair. In summary, this design not only improves the operational accuracy and reliability of the hoisting equipment but also enhances its adaptability and ease of maintenance, making it more suitable for diverse hoisting operation environments.
