Description

Technical Field

[0001] This invention relates to the field of safety control technology for logistics transportation equipment, and more specifically, to a station-driven pallet truck. Furthermore, it also relates to a driving safety protection and control method applied to the aforementioned station-driven pallet truck. Background Technology

[0002] Pallet trucks are widely used in supermarkets, logistics, and express delivery industries for cargo transfer, loading and unloading, transportation, and picking operations. Due to the numerous tasks and large volumes of goods, and the fact that most companies pay workers on a piece-rate basis, workers prioritize efficiency while driving pallet trucks, neglecting driving safety and engaging in improper operation. Visits to these companies in various regions revealed that workplace injuries due to improper driving occur every year. One frequently occurring improper driving behavior is the driver extending their legs or feet beyond the vehicle's protective perimeter, leading to accidents. Therefore, there is an urgent need to address the safety control issues of these vehicles.

[0003] In existing technologies, only the pedal switch is generally used to detect whether the driver is standing on the pedal. The vehicle is only allowed to run when the driver stands on the pedal and triggers the pedal switch. However, in reality, the driver can trigger the pedal switch even if one foot is on the pedal and the other foot is outside the vehicle's outline. The vehicle can still drive, which fails to provide effective protection for the driver's legs and feet.

[0004] In summary, how to effectively detect whether the driver's legs and feet are within the safe range of the vehicle body, and promptly slow down and stop the vehicle while issuing an alarm to ensure safe operation, and guarantee both economic and personnel safety, is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a stand-mounted pallet truck that can effectively detect whether the driver's legs and feet are within the safe range of the vehicle body, and promptly slow down and stop the vehicle while issuing an alarm to ensure safe operation and guarantee both economic efficiency and personnel safety.

[0006] Another objective of this invention is to provide a driving safety protection and control method for the aforementioned station-driven pallet truck.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A stand-mounted pallet truck, comprising:

[0009] Vehicle body;

[0010] A pedal switch is located on the pedal of the vehicle body, and the pedal switch is used to detect whether the driver is standing on the pedal;

[0011] At least one leg detection switch is provided in an area where the driver is likely to extend his legs out of the vehicle body, the leg detection switch being used to detect whether the driver's legs are outside the safe range of the vehicle body;

[0012] An alarm, which is installed on the vehicle body, is used to sound an alarm when the driver's legs are detected to be outside the safe range;

[0013] An accelerator is mounted on the vehicle body;

[0014] A speed sensor is mounted on the motor of the vehicle body;

[0015] The controller is connected to the pedal switch, the leg detection switch, the alarm, the accelerator, the speed sensor, and the motor, respectively, to control the operation of the motor and the alarm based on the status of the pedal switch and the leg detection switch, and the signals from the accelerator and the speed sensor.

[0016] In one embodiment, the leg detection switch includes a photoelectric switch.

[0017] In one embodiment, the alarm includes at least one of a buzzer, a warning icon on the vehicle's display screen, and a vibration device for controlling the vibration of the vehicle's operating handle.

[0018] In one embodiment, a display screen is also included, which is connected to the controller.

[0019] A driving safety protection and control method, applied to any of the above-mentioned stand-drive pallet trucks, comprising:

[0020] After the vehicle is powered on, it is determined whether the pedals of the vehicle body are triggered. If not, the vehicle body is prohibited from driving and the alarm is controlled to not sound. If so, it is determined whether there is an accelerator signal input.

[0021] If not, the vehicle is prohibited from driving, and the trigger time of the leg detection switch is obtained. If the trigger time of the leg detection switch is less than t1, the alarm is controlled not to sound. If an accelerator signal is input at this time, the alarm is controlled to sound immediately. If the trigger time of the leg detection switch is greater than or equal to t1, the alarm is controlled to sound.

[0022] If so, control the vehicle to move and execute a differentiated control strategy based on the vehicle's speed.

[0023] In one embodiment, the execution of a differentiated control strategy based on the vehicle's travel speed includes,

[0024] The vehicle's running speed is obtained. If the running speed is less than v1, the trigger time of the leg detection switch is obtained. If the trigger time of the leg detection switch is less than t2, the vehicle is controlled not to decelerate and the alarm is not triggered. If the trigger time of the leg detection switch is greater than or equal to t2, the vehicle is controlled to decelerate to a stop and the alarm is triggered.

[0025] If the running speed is greater than or equal to v1, the trigger time of the leg detection switch is obtained. If the trigger time of the leg detection switch is less than t3, the vehicle body is controlled not to decelerate and the alarm is not triggered. If the trigger time of the leg detection switch is greater than or equal to t3, the vehicle body is controlled to decelerate to a stop and the alarm is triggered.

[0026] In one embodiment, the step of controlling the vehicle to decelerate to a stop if the trigger time of the leg detection switch is greater than or equal to t2 includes:

[0027] If the trigger time of the leg detection switch is greater than or equal to t2, then the vehicle body is controlled to decelerate to a stop at a deceleration rate a1.

[0028] In one embodiment, the step of controlling the vehicle to decelerate to a stop if the trigger time of the leg detection switch is greater than or equal to t3 includes:

[0029] If the trigger time of the leg detection switch is greater than or equal to t3, then the vehicle body is controlled to decelerate to v1 at a deceleration rate a2, and then decelerate to a stop at a deceleration rate a1.

[0030] In one embodiment, during the process of controlling the vehicle to decelerate to a stop, if the leg detection switch is no longer triggered and the accelerator signal continues to be input, the vehicle is controlled to recover from the current speed to the driving speed corresponding to the accelerator signal, and the alarm is controlled to stop alarming after a preset time.

[0031] In one embodiment, t1, t2, and t3 are all the same or different from each other, and the deceleration rate a2 is greater than the deceleration rate a1.

[0032] When using the stand-mounted pallet truck provided by this invention, at least one leg detection switch is installed in an area where the driver can easily extend their legs. A tiered control strategy is executed based on the pedal state detected by the pedal switch, the vehicle's speed detected by the speed sensor, and the leg extension status and duration detected by the leg detection switch. For example, if the pedal switch is not triggered, the vehicle cannot move regardless of whether there is an accelerator signal. In this case, even if the driver triggers the leg detection switch, the alarm will not sound.

[0033] If the pedal switch is triggered, the controller can determine whether there is an accelerator signal input (if the accelerator is triggered, an accelerator signal can be input; if the accelerator is not triggered, no accelerator signal is input). If there is no accelerator signal input, the controller stops the vehicle from moving and obtains the trigger time of the leg detection switch. If the trigger time of the leg detection switch is less than t1, the controller does not trigger the alarm. If an accelerator signal is input at this time, the controller immediately triggers the alarm. If the trigger time of the leg detection switch is greater than or equal to t1, the controller triggers the alarm. If there is an accelerator signal input, the controller moves the vehicle and executes a differentiated control strategy based on the vehicle's speed. Ultimately, this achieves differentiated control that allows for short-term false triggering when the vehicle is stationary, delays deceleration to ensure smooth operation when the vehicle is moving at low speeds, and rapidly decelerates and triggers an alarm when the vehicle is moving at high speeds.

[0034] Therefore, by using the pallet truck provided in this application, if the driver's legs extend outside the vehicle body outline during driving, they may collide with goods or other items, causing injury to the driver. Due to the addition of at least one leg detection switch, once the driver's legs are detected to be outside the safe range of the vehicle body, the vehicle will decelerate until it stops, preventing the driver from unintentionally or intentionally placing their legs in that area to trigger the switch. The alarm can remind the driver, so that the driver can regulate their driving habits.

[0035] In summary, the stand-mounted pallet truck provided by this invention can effectively detect whether the driver's legs and feet are within the safe range of the vehicle body, promptly slow down and stop the vehicle while issuing an alarm, ensuring safe operation and guaranteeing both economic benefits and personnel safety.

[0036] In addition, the present invention also provides a driving safety protection and control method for the above-mentioned station-driven pallet truck. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] The core of this invention is to provide a stand-mounted pallet truck that can effectively detect whether the driver's legs and feet are within the safe range of the vehicle body, promptly slow down and stop the vehicle while issuing an alarm, ensuring safe operation and guaranteeing both economic efficiency and personnel safety. Another core aspect of this invention is to provide a driving safety protection and control method applied to the aforementioned stand-mounted pallet truck.

[0046] Please refer to Figure 1 This specific embodiment provides a stand-mounted pallet truck, including:

[0047] Vehicle body 1;

[0048] The pedal switch 2 is located on the pedal of the vehicle body 1. The pedal switch 2 is used to detect whether the driver is standing on the pedal.

[0049] At least one leg detection switch 3 is provided in an area where the driver can easily extend his legs out of the vehicle body 1. The leg detection switch 3 is used to detect whether the driver's legs are outside the safe range of the vehicle body 1.

[0050] Alarm 4, which is installed on the vehicle body 1, is used to sound an alarm when the driver's legs are detected to be outside the safe range;

[0051] Accelerator 5, which is mounted on vehicle body 1;

[0052] The speed sensor is located on the motor of vehicle body 1;

[0053] The controller is connected to the pedal switch 2, the leg detection switch 3, the alarm 4, the accelerator 5, the speed sensor, and the motor, respectively, to control the operation of the motor (or the drive system of the vehicle body 1) and the alarm 4 based on the status of the pedal switch 2 and the leg detection switch 3, the signals of the accelerator 5 and the speed sensor.

[0054] It should be noted that, to protect the driver's safety, when the driver extends their feet or legs beyond the outline of the vehicle body 1, the leg detection switch 3 can detect in real time that the driver's legs or feet have exceeded the safe range of the vehicle body 1. Upon receiving this detection signal, the controller activates the alarm 4 to warn the driver and simultaneously controls the drive system of the vehicle body 1 to perform relevant actions, protecting the driver from injury. Moreover, by installing multiple leg detection switches 3 in areas where the driver is likely to extend their legs or feet beyond the vehicle body 1, the detection area can be effectively expanded, effectively ensuring the driver's operational safety.

[0055] It should also be noted that the accelerator 5 is used to input accelerator signals or accelerate the vehicle. A speed sensor is installed on the motor of the vehicle body 1 to provide real-time feedback of the detected vehicle body 1's speed to the controller. In practical applications, the shape, type, location, and number of the vehicle body 1, pedal switch 2, leg detection switch 3, alarm 4, and controller can be determined according to actual conditions and requirements.

[0056] In one embodiment, the leg detection switch 3 includes a photoelectric switch. The photoelectric switch detects the presence, position, and distance of an object by emitting and receiving light signals, enabling non-contact automatic sensing and control.

[0057] In one embodiment, the alarm 4 includes at least one of a buzzer, a warning icon on the display screen of the vehicle body 1, and a vibration device for controlling the vibration of the operating handle of the vehicle body 1. The type of alarm 4 can be determined in actual use based on the specific circumstances and needs.

[0058] In one embodiment, a display screen is also included, which is connected to the controller. For example, data related to the operation of the vehicle body 1 can be displayed on the display screen so that the operator can view the operation of the vehicle body 1 in real time.

[0059] In addition to the aforementioned stand-and-drive pallet truck, the present invention also provides a driving safety protection and control method applied to the aforementioned stand-and-drive pallet truck, the driving safety protection and control method comprising:

[0060] Step S1: Power on the entire vehicle (i.e., power on vehicle body 1);

[0061] Step S2: Determine whether the pedal of vehicle body 1 is triggered. If not, prohibit vehicle body 1 from driving and control alarm 4 to not sound.

[0062] Step S3: If yes, determine whether there is an accelerator signal input; if no, prohibit the vehicle body 1 from driving and obtain the trigger time of the leg detection switch 3. If the trigger time of the leg detection switch 3 is less than t1, control the alarm 4 not to alarm. If an accelerator signal is input at this time, control the alarm 4 to alarm immediately; if the trigger time of the leg detection switch 3 is greater than or equal to t1, control the alarm 4 to alarm.

[0063] If so, control vehicle 1 to move and execute differentiated control strategies based on the speed of vehicle 1.

[0064] In one embodiment, a differentiated control strategy is executed based on the driving speed of the vehicle body 1, including:

[0065] Get the running speed of vehicle 1. If the running speed is less than v1, get the trigger time of leg detection switch 3. If the trigger time of leg detection switch 3 is less than t2, control vehicle 1 not to decelerate and alarm 4 not to alarm. If the trigger time of leg detection switch 3 is greater than or equal to t2, control vehicle 1 to decelerate to stop and control alarm 4 to alarm.

[0066] If the running speed is greater than or equal to v1, the trigger time of the leg detection switch 3 is obtained. If the trigger time of the leg detection switch 3 is less than t3, the vehicle body 1 is controlled not to decelerate and the alarm 4 is not alarmed. If the trigger time of the leg detection switch 3 is greater than or equal to t3, the vehicle body 1 is controlled to decelerate to a stop, and the alarm 4 is controlled to alarm.

[0067] In one embodiment, if the triggering time of the leg detection switch 3 is greater than or equal to t2, then the vehicle body 1 is controlled to decelerate to a stop, including:

[0068] If the trigger time of the leg detection switch 3 is greater than or equal to t2, then the vehicle body 1 is controlled to decelerate to a stop at a deceleration rate a1.

[0069] In one embodiment, if the triggering time of the leg detection switch 3 is greater than or equal to t3, the vehicle body 1 is controlled to decelerate to a stop, including:

[0070] If the trigger time of the leg detection switch 3 is greater than or equal to t3, then the vehicle body 1 is controlled to decelerate to v1 at a deceleration rate a2, and then decelerate to a stop at a deceleration rate a1.

[0071] In one embodiment, during the process of controlling the vehicle body 1 to decelerate to a stop, if the leg detection switch 3 is no longer triggered and the accelerator signal continues to be input, the vehicle body 1 is controlled to recover from the current speed to the driving speed corresponding to the accelerator signal, and the alarm 4 is controlled to stop alarming after a preset time.

[0072] In one embodiment, t1, t2, and t3 may be the same or different from each other, and the deceleration rate a2 is greater than the deceleration rate a1. This is because the driver is in a dangerous situation and needs to reduce the speed to a low level as quickly as possible; therefore, the deceleration rate a2 is greater than the deceleration rate a1. The deceleration diagram is shown below. Figure 4 As shown.

[0073] To further illustrate the driving safety protection and control method for the aforementioned station-driven pallet truck provided in this application, such as Figure 3 As shown, we will now illustrate this with examples.

[0074] A. Powering on the entire vehicle body 1 (for example, a power-on switch 6 can be installed on the vehicle body 1; pressing the power-on switch 6 will power on the entire vehicle). If the pedal switch 2 is not triggered, the vehicle will not move regardless of whether there is an accelerator signal input to the vehicle body 1. At this time, even if the driver triggers the leg detection switch 3, the alarm 4 will not sound.

[0075] B. When the vehicle body 1 is powered on, if the pedal switch 2 is triggered, it is determined whether there is an accelerator driving signal on the vehicle body 1 (wherein, if the accelerator 5 is triggered, an accelerator signal can be input; if the accelerator 5 is not triggered, no accelerator signal is input). If there is no accelerator signal input, the vehicle body 1 is prohibited from driving. At this time, the driver triggers the leg detection switch 3. The controller can obtain the triggering time of the leg detection switch 3. If the triggering time of the leg detection switch 3 is less than t1, the alarm 4 is not controlled to sound. If there is an accelerator signal input at this time, the alarm 4 is controlled to sound immediately. If the triggering time of the leg detection switch 3 is greater than or equal to t1, the alarm 4 is controlled to sound. Since the vehicle body 1 is stationary in this situation, the safety hazard is small, so t1 can be relatively long. In this example, the value is set to 2s.

[0076] C. Upon powering on vehicle body 1, if pedal switch 2 is triggered, determine if vehicle body 1 has an accelerator driving signal. If an accelerator signal is input, execute a differentiated control strategy based on the vehicle body 1's speed. The vehicle body 1's speed is determined by the magnitude of the input signal. For example, the speed can be divided into a low-speed segment (0 < v < v1) and a high-speed segment (v ≥ v1). v1 is the node distinguishing between low and high speeds, typically set based on vehicle type or maximum speed. Setting low and high speeds aims to consider different safety and driving strategies at different speeds. In the low-speed segment, the driver has more reaction time, prioritizing vehicle comfort and smoothness; in the high-speed segment, driver safety is prioritized, with rapid deceleration in dangerous situations. For example, v1 can be set to 3 km / h.

[0077] C1. When the driving speed is 0 < v < v1, in the low-speed range, the driver triggers the leg detection switch 3. The trigger time of the leg detection switch 3 is recorded. If the trigger time is less than t2, the vehicle body 1 is controlled not to decelerate, and the alarm 4 is not activated. If the trigger time is greater than or equal to t2, the vehicle body 1 is controlled to decelerate to a stop at a deceleration rate a1, and the alarm 4 continues to emit a warning sound. Furthermore, during deceleration, if the driver does not trigger the leg detection switch 3 again, and the acceleration signal is not interrupted, the vehicle returns to the speed corresponding to the acceleration signal, and the alarm 4 stops 2 seconds later. Because the vehicle is in a low-speed state in this situation, the safety hazard is small, so t2 can be set relatively long; in this example, it is set to 2 seconds. Considering smooth driving, after the driver triggers the alarm and realizes the safety issue, and simultaneously retracts their legs to eliminate the safety hazard, the vehicle body 1 can then resume normal driving.

[0078] C2. When the driving speed is v≥v1, in the high-speed range, the driver triggers the leg and foot detection switch 3. The trigger time of the leg and foot detection switch 3 is obtained. If the trigger time of the leg and foot detection switch 3 is less than t3, the vehicle body 1 is controlled not to decelerate, and the alarm 4 is controlled not to emit a warning sound. If the trigger time of the leg and foot detection switch 3 is greater than or equal to t3, the vehicle body 1 is controlled to decelerate from the current speed to v1 at a deceleration rate a2, and then from v1 to 0 at a deceleration rate a1, while the alarm 4 continuously emits a warning sound. Furthermore, during deceleration, if the driver does not trigger the leg and foot detection switch 3 again, and the acceleration signal is not interrupted, the vehicle returns to the speed corresponding to the acceleration signal from the current speed, and the alarm 4 stops emitting a warning sound after 2 seconds. Because the vehicle is in a high-speed state in this situation, it needs to quickly enter the protection state, so t3 needs to be short. In this example, the t3 setting value is 0.2s. This is also to ensure smooth driving. After the driver triggers the alarm and realizes the safety issue, he can then remove his legs to eliminate the safety hazard and allow the vehicle to resume normal driving.

[0079] It should be added that if the driver's legs extend outside the outline of the vehicle body 1 during driving, they may collide with cargo or other objects, causing injury to the driver. Therefore, a leg detection switch 3 has been specially added. Once the leg detection switch 3 detects that the driver's legs are outside the safe range of the vehicle body 1, the vehicle body 1 will slow down until it stops, to prevent the driver from unconsciously or consciously placing his legs in that area to trigger the switch, and to remind the driver to regulate his driving habits.

[0080] Furthermore, this application specifies the triggering time of the leg and foot detection switch 3 to avoid frequent deceleration and stopping alarms caused by short-term false triggering, which would affect normal driving. In addition, this application divides driving speed into low-speed and high-speed scenarios, each with different alarm strategies. At low speeds, the driver has more reaction time, prioritizing vehicle comfort and smoothness; at high speeds, driver safety is given greater consideration, with priority given to rapidly reducing vehicle speed in dangerous situations. After the safety hazard is eliminated, the vehicle returns to normal driving status, ensuring smooth driving.

[0081] In addition, it should be noted that the orientation or positional relationship indicated by "upper" and other terms in this application is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the purpose of simplifying the description and making it easier to understand, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.
