Description

Technical Field

[0001] This utility model relates to the field of foot switch technology, specifically a foot switch for aerial work vehicles. Background Technology

[0002] In actual operation scenarios of aerial work platforms, when the driver is in the work platform and operating the vehicle, he needs to coordinate his hands and feet to accurately operate the foot switch and control handle. Among them, the foot switch plays a crucial role, as it is the core switch that ensures the safe use of the aerial work platform.

[0003] However, current foot switches have revealed many serious problems in practical applications, such as the poor operating habits of some drivers. Some drivers, for convenience, deliberately block the foot switch, leaving it constantly energized. While this may seem to save the trouble of frequent pedaling, it actually renders the foot switch ineffective, placing the vehicle in extreme danger.

[0004] When the foot switch remains energized for the reasons mentioned above, causing a failure of the safety mechanism, a series of serious chain reactions will occur. Under normal circumstances, the power supply to the operating handle should be disconnected when the foot switch is not pressed to prevent accidental vehicle operation. However, if the foot switch is intentionally blocked, the power supply to the operating handle will remain connected. In this case, if the operating handle is accidentally touched or interfered with by external factors, such as in a real-world production scenario where, during sandblasting operations, the air duct of the sandblasting suit accidentally jams the handle while the foot switch is intentionally blocked, causing a short circuit in the power supply to the operating handle, the vehicle will suddenly move automatically, posing a significant threat to the workers and the surrounding environment.

[0005] In summary, the foot switch on aerial work platforms is subject to unsafe behavior by some drivers who intentionally block it, which severely weakens its safety function, increases the probability of automatic malfunctions, and poses a significant challenge to the safety of aerial work operations. Therefore, this paper proposes a foot switch for aerial work platforms. Utility Model Content

[0007] To achieve the above objectives, this utility model provides the following technical solution: a foot switch for an aerial work platform, comprising: a base plate, a foot pedal, and an operating handle. A waterproof box is provided on one side of the top of the base plate. A rotating shaft is provided inside the waterproof box, with both ends of the rotating shaft extending out of the waterproof box. Foot pedals are fixed to both ends of the rotating shaft. A return spring is provided between the base plate and the foot pedal. A paddle is fixed to the outer wall of the middle part of the rotating shaft. A controller is provided inside the waterproof box. A watertight contact switch is provided on the outer wall of the controller near the paddle. A timer and a communication module are integrated inside the controller. The communication module is used for communication between the controller and the operating handle.

[0008] As a further explanation of this utility model, the communication module includes a wired communication module and a wireless communication module. The controller has a signal line interface for connecting the wired communication module on one side. The wireless communication module includes 4G / 5G communication or WiFi wireless communication.

[0009] As a further explanation of this utility model, the operating handle is electrically connected to a power management module, which is used to control the power supply to the operating handle.

[0010] As a further explanation of this utility model, the operating handle also includes an audible and visual alarm module, which emits corresponding audible and visual alarm signals according to the instructions issued by the controller.

[0011] As a further explanation of this utility model, the controller also includes a data storage module, which is used to store various data during the operation of the controller.

[0012] As a further explanation of this utility model, the top surface of the foot pedal is provided with a strip-shaped anti-slip groove, and the top of the base plate is provided with a protective cover, which is located on the outside of the waterproof box and the foot pedal.

[0013] As a further explanation of this utility model, the timer is used to record the idle time of the operating handle, and the preset time of the timer is - seconds.

[0014] As a further explanation of this utility model, when the foot pedal is pressed down, the paddle can rotate toward the watertight contact switch side.

[0015] As a further explanation of this utility model, the bottom end of the return spring is fixed to the top surface of the base plate, and the top end is fixed to the bottom surface of the foot pedal. The return spring is made of stainless steel.

[0016] As a further explanation of this utility model, the controller integrates an embedded microprocessor, and the power management module adopts a soft-start circuit and a soft-shutdown circuit for power switching.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This invention uses a controller to analyze and process signals from sensors according to a preset program logic. When an action signal is detected on the operating handle, the watertight contact switch signal is checked. If the foot switch is pressed, the operating handle is allowed to work normally; otherwise, a command to cut off the power to the operating handle is issued. This logical judgment mechanism ensures that the operating handle can only work effectively when the foot switch is properly pressed, avoiding misoperation caused by foot switch failure, including being blocked by someone.

[0018] When the handle is not operated and the foot switch remains depressed, the controller starts an internal timer. After a preset 5 seconds, it issues a command to cut off the power to the handle. This function addresses situations where the driver may block the foot switch for an extended period. Even if the foot switch is manually kept depressed and the handle is not operated, the power to the handle will be automatically cut off within a specified time, preventing automatic malfunctions caused by prolonged power supply.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1: Please refer to Figures 1-9 This utility model provides a technical solution: a foot switch for an aerial work platform, comprising: a base plate 1, a foot pedal 5, and an operating handle. A waterproof box 3 is provided on one side of the top of the base plate 1. A rotating shaft 4 is located inside the waterproof box 3, with both ends of the rotating shaft 4 extending out of the waterproof box 3. The waterproof box 3 is fixed to the base plate 1, providing a waterproof environment for the internal components. The base plate 1 provides basic support for the entire foot switch. The waterproof box 3, fixed to the base plate 1, effectively prevents internal electronic components such as the controller 8 from being damaged by moisture, ensuring the normal operation of the equipment in complex environments. Foot pedals 5 are fixed to both ends of the rotating shaft 4, and the rotating shaft 4 is rotatably connected to the waterproof box 3. The rotating shaft 4 can rotate as the foot pedal 5 is pressed down and reset. A reset spring 6 is provided between the base plate 1 and the foot pedal 5, which resets the foot pedal 5 after it is pressed down. A lever 7 is fixed to the outer wall of the middle section of the rotating shaft 4. A controller 8 is located inside the waterproof box 3. A watertight contact switch 9 is located on the outer wall of the controller 8 near the lever 7. When the foot pedal 5 is pressed down, the rotating shaft 4 drives the lever 7 to rotate. The lever 7 can rotate towards the watertight contact switch 9, thereby triggering the watertight contact switch 9 to send a signal to the controller 8. The lever 7 is fixed to the middle of the rotating shaft 4. When the foot pedal 5 is pressed down, causing the rotating shaft 4 to rotate, the lever 7 rotates accordingly and moves towards the watertight contact switch 9, triggering the watertight contact switch 9 to generate a signal. This signal is transmitted to the controller 8, realizing the conversion from mechanical action to electrical signal, which is a key link in switch control.

[0024] The controller 8 integrates a timer 802 and a communication module. The communication module is used for communication between the controller 8 and the operating handle. When the foot pedal 5 is pressed down, the lever 7 can rotate towards the watertight contact switch 9. As the core control component, the controller 8 receives signals from the watertight contact switch 9, records the idle time of the operating handle through the timer 802, and interacts with the operating handle through the communication module to achieve intelligent control of the entire foot switch system.

[0025] The bottom end of the return spring 6 is fixed to the top surface of the base plate 1, and the top end is fixed to the bottom surface of the foot pedal 5. The return spring 6 is made of stainless steel. The top surface of the foot pedal 5 has a strip-shaped anti-slip groove, increasing the friction between the foot and the foot pedal 5, preventing operators from slipping and misoperating during high-altitude work, thus improving operational safety and stability. A protective cover 2 is located on the top of the base plate 1, outside the waterproof box 3 and the foot pedal 5. The protective cover 2 provides additional physical protection to the waterproof box 3 and the foot pedal 5, preventing damage from external objects and further ensuring the normal operation of the equipment. The two ends of the return spring 6 are fixed to the base plate 1 and the foot pedal 5 respectively. When the foot pedal 5 is pressed down, the return spring 6 is compressed. When the external force disappears, the return spring 6 uses its own elasticity to automatically reset the foot pedal 5, facilitating the next operation. The stainless steel material ensures the spring's durability and corrosion resistance.

[0029] In this embodiment, the communication module includes a wired communication module and a wireless communication module. A signal line interface 10 for connecting the wired communication module is provided on one side of the controller 8. The wireless communication module includes 4G / 5G communication or WiFi wireless communication. The wired communication module can be connected via the signal line interface 10 to achieve wired communication with the operating handle, ensuring stable wired communication between the controller 8 and the operating handle. The 4G / 5G or WiFi wireless communication module provides a more flexible communication method, facilitating use in different scenarios and ensuring smooth information transmission between the controller 8 and the operating handle.

[0030] After connecting the wired communication module through the signal line interface 10, wired communication between the controller 8 and the operating handle can be realized. Wired communication has many significant advantages. First, its signal transmission stability is extremely high. In industrial environments, there are various sources of electromagnetic interference, such as large motors and high-voltage cables. These sources of interference can seriously affect wireless signals, causing signal loss or distortion. Wired communication transmits signals through physical lines, effectively shielding external electromagnetic interference and ensuring the integrity and accuracy of the signal during transmission. For example, when an aerial work platform is performing complex operations, multiple electronic devices may be operating simultaneously. Wired communication can ensure the accurate transmission of instructions and data between the controller 8 and the operating handle, avoiding misoperation caused by signal interference.

[0031] 4G / 5G communication boasts wide coverage and high-speed data transmission capabilities. When aerial work platforms are operating over long distances or moving between different areas, 4G / 5G networks ensure a constant communication connection between the controller 8 and the operating handle. For example, in large construction sites or field operations where the work area may span a significant geographical region, 4G / 5G communication can overcome distance limitations and enable real-time communication. Furthermore, the high speed and low latency of 5G communication meet the demands of applications with extremely high real-time requirements, such as remotely and precisely controlling the complex movements of the aerial work platform. Operators can obtain real-time status information from the operating handle via a remote terminal and quickly issue control commands, achieving efficient and safe remote operation. When the aerial work platform is used for indoor equipment installation or maintenance, by establishing a WiFi network, operators can freely move the operating handle within a certain range while maintaining uninterrupted communication with the controller 8, improving operational flexibility and convenience.

[0032] The controller 8 integrates an embedded microprocessor, which can quickly process various signals and control the operation of each module, achieving precise control and efficient management of the foot switch system and improving the overall performance of the equipment. The embedded microprocessor achieves precise control and efficient management of the foot switch system through data interaction with various modules. For example, when the foot switch sensor and the operating handle sensor transmit detected signals to the controller 8, the embedded microprocessor quickly analyzes and processes these signals. It determines whether the status of the foot switch and the operation of the operating handle comply with safety regulations based on preset program logic. If an abnormality is detected, such as the foot switch not being pressed while the operating handle is activated, the embedded microprocessor immediately issues a command to cut off the power to the operating handle through the power management module to prevent malfunction of the vehicle.

[0033] Embedded microprocessors can also monitor the system's operating status in real time, including parameters such as the signal strength of the communication module and the voltage and current of the power management module. Through real-time monitoring and analysis of these parameters, the embedded microprocessor can promptly identify potential problems in the system and take corresponding measures for adjustment and optimization. For example, when a weakening signal strength is detected in the communication module, the embedded microprocessor can automatically switch to a more stable communication mode to ensure communication continuity; when voltage fluctuations occur in the power management module, the embedded microprocessor can adjust the power output to protect the circuit components of the operating handle from damage.

[0034] The power management module employs soft-start and soft-shutdown circuits for power switching. The operating handle is electrically connected to the power management module, which controls the power supply to the operating handle. The power management module controls the power supply to the operating handle through the soft-start and soft-shutdown circuits. Soft-start avoids the large current surge during startup, while soft-shutdown reduces voltage fluctuations during shutdown, effectively protecting the circuit components of the operating handle and extending the device's lifespan. The soft-shutdown circuit reduces voltage fluctuations when the operating handle is closed. When the operating handle needs to be closed, the traditional method of directly cutting off the power causes a rapid drop in voltage in the circuit, resulting in significant voltage fluctuations. These voltage fluctuations may affect the internal storage components of the operating handle, leading to data loss or corruption, and may also interfere with other connected devices.

[0035] The soft-shutdown circuit achieves a smooth shutdown of the control handle by gradually reducing the output voltage. When the power management module receives a command to shut down the control handle, the soft-shutdown circuit begins to slowly reduce the output voltage, completely cutting off power after a certain time delay. During this process, the internal circuitry of the control handle has sufficient time to adjust its state, avoiding problems caused by sudden voltage changes.

[0036] For example, the control handle may contain memory chips for storing operating parameters. If the power is cut off directly, the data in the memory chips may be lost or damaged due to voltage fluctuations. However, by using a soft-shutdown circuit, the voltage drops slowly, giving the memory chips enough time to safely save the data, without interfering with other connected devices, thus improving the stability and reliability of the system.

[0037] The operating handle also includes an audible and visual alarm module, which emits corresponding audible and visual alarm signals based on instructions from the controller 8. This allows for timely feedback of equipment status information, such as malfunctions or abnormal operations, to the operator, improving operational safety and convenience. The audible and visual alarm module is connected to the controller 8 via a communication line. The controller 8 monitors the system's operating status in real time and sends corresponding instructions to the audible and visual alarm module when it detects an abnormality or needs to alert the operator. Upon receiving the instructions, the audible and visual alarm module emits sound signals of specific frequency and intensity, as well as light signals of different colors and flashing frequencies, according to the instructions.

[0038] For example, if the foot switch is not pressed but the operating handle is activated, the controller 8 will determine this as an abnormal operation and immediately send an alarm command to the audible and visual alarm module. Upon receiving the command, the audible and visual alarm module will emit a rapid alarm sound, while a red indicator light flashes rapidly to attract the operator's attention and remind them to correct the operation in time.

[0039] The controller 8 also includes a data storage module 801, which stores various data generated during the operation of the controller 8. This data storage module 801 stores various data such as operation records and fault information, facilitating subsequent equipment maintenance, troubleshooting, and performance analysis. The inclusion of the data storage module 801 has several significant benefits. In terms of equipment maintenance, maintenance personnel can read the data in the data storage module 801 to understand the equipment's operating history and fault conditions, enabling targeted maintenance and upkeep. For example, based on operation records and fault information, maintenance personnel can identify which components are prone to failure, prepare spare parts in advance, shorten maintenance time, and improve equipment availability.

[0040] In terms of troubleshooting, the data storage module 801 provides detailed fault information, helping maintenance personnel quickly locate the cause of the fault. Traditional troubleshooting methods often require a lot of time and effort to check each problem one by one, but by analyzing the data in the data storage module 801, maintenance personnel can quickly narrow down the scope of the fault, improving the accuracy and efficiency of troubleshooting.

[0041] In terms of performance analysis, long-term monitoring and analysis of system operating parameters can reveal the performance trends of the system, providing a basis for equipment optimization and upgrades. For example, if the system temperature continues to rise during operation, it may indicate a problem with the system's heat dissipation performance, requiring improvement of the heat dissipation system; if the system's energy consumption gradually increases, it may be necessary to optimize the design of the power management module to improve energy efficiency.

[0042] Timer 802 is used to record the idle time of the operating handle. The preset time for timer 802 is 5-10 seconds. Timer 802 has a preset idle time recording function of 5-10 seconds. When the idle time of the operating handle exceeds the preset value, the controller 8 can take corresponding actions based on this information, such as automatically turning off the operating handle to prevent accidental activation. Timer 802 monitors the status of the operating handle in real time. When the operating handle is in an inactive state, timer 802 starts timing. If the operating handle still does not move within the preset 5-10 seconds, timer 802 will send a signal to the controller 8, indicating that the operating handle has been idle for longer than the preset time. After receiving the signal, the controller 8 can take corresponding actions according to the preset program, such as automatically turning off the power of the operating handle to avoid accidental activation and save energy.

[0043] In terms of safety, when the operator temporarily leaves the control handle or forgets to turn it off, timer 802 can automatically detect the idle state of the control handle and automatically turn off the power after a preset time. This can avoid accidental operation caused by the control handle being powered on for a long time, reducing the risk of safety accidents. For example, when the aerial work platform is performing high-altitude operations, if the operator leaves the control handle to perform other work, but the control handle is still powered on, it may be accidentally touched by other people, causing the vehicle to malfunction and resulting in a safety accident. The automatic shutdown function of timer 802 can effectively prevent this from happening.

[0044] In terms of energy saving, the automatic shut-off function of Timer 802 can reduce the energy consumption of the operating handle when it is idle. Even when not in use, the operating handle consumes some electrical energy while powered on. The automatic shut-off function of Timer 802 can promptly cut off the power when the operating handle is idle, reducing the equipment's energy consumption, extending battery life, and improving the equipment's economy and environmental friendliness.

[0045] Furthermore, the preset time of Timer 802 can be adjusted according to actual operational needs, offering a degree of flexibility. In different operational scenarios, operators may have varying requirements for the idle time of the control handle. For example, in operations requiring high continuity, the preset time can be appropriately extended; while in operations with high energy-saving and safety requirements, the preset time can be appropriately shortened. By adjusting the preset time of Timer 802, the needs of different operational scenarios can be better met, improving the system's applicability and practicality.

[0046] This invention uses a controller 8 to analyze and process signals from sensors according to a preset program logic. When an action signal is detected on the operating handle, the signal of the watertight contact switch 9 is checked. If the foot switch is pressed, the operating handle is allowed to work normally; otherwise, a command to cut off the power to the operating handle is issued. This logical judgment mechanism ensures that the operating handle can only work effectively when the foot switch is pressed normally, avoiding misoperation caused by foot switch failure, including being blocked by someone.

[0047] When the handle is not operated and the foot switch remains depressed, the controller 8 starts the internal timer 802 to count down. When the countdown reaches the preset 5 seconds, a command is issued to cut off the power to the handle. This function is designed for situations where the driver may block the foot switch for an extended period of time. Even if the foot switch is manually kept depressed and the handle is not operated, the power to the handle will be automatically cut off within a specified time to prevent the vehicle from malfunctioning due to prolonged power supply.

[0048] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
