[0054] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0055] It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention.

[0056] Reference Figure 1 , Figure 1 This is a structural diagram of a first embodiment of the automatic belt take-up and take-up system of the present invention. The automatic belt take-up and take-up system includes: a pressure acquisition module 100, a control module 200, and a power module 300; the pressure acquisition module 100 is electrically connected to the control module 200; the control module 200 is electrically connected to the power module 300; and the power module 300 is movably connected to the belt harness.

[0057] The pressure acquisition module 100 is used to acquire external pressure to generate a pressure value signal and transmit the pressure value signal to the control module 200.

[0058] It should be noted that the pressure acquisition module can be a device capable of measuring pressure and providing remote electrical signals. Examples include strain gauge pressure sensors, piezoresistive pressure sensors, capacitive pressure sensors, piezoelectric pressure sensors, inductive pressure sensors, Hall effect pressure sensors, eddy current pressure sensors, and vibrating wire pressure sensors.

[0059] In a specific implementation, taking a capacitive pressure sensor as an example, the capacitive pressure sensor uses a circular metal thin film or a metal-plated thin film as one electrode of a capacitor. When the film deforms under pressure, the capacitance formed between the film and the fixed electrode changes. By measuring the capacitance value through a measuring circuit, an electrical signal that is related to the pressure magnitude can be output to the control module 200.

[0060] The control module 200 is used to compare the pressure value signal with a preset pressure signal, and generate and output a control signal to the power module 300 based on the comparison result.

[0061] It should be noted that the control module can be a controller, circuit board, or microcontroller with certain data processing capabilities.

[0062] In its implementation, the control module compares the pressure signal with a preset pressure signal, thereby comparing the pressure received by the pressure acquisition module with the preset pressure value. It is understood that the pressure received by the pressure acquisition module is difficult to maintain at a fixed value. Therefore, in practical applications, a preset pressure range can be used. The control module performs pressure range detection. When the detected pressure value is lower than the preset pressure range value, a control signal is output to the power module to automatically fine-tighten the belt assembly; when the detected pressure value is higher than the preset pressure range value, a control signal is output to the power module to automatically fine-tighten the belt assembly.

[0063] The power module 300 is used to adjust the belt according to the control signal and control the belt's extension and retraction.

[0064] It should be noted that the power module may be a device that is movably connected to the strap and capable of moving the strap.

[0065] In a practical implementation, a motor can be connected to a gear, which rotates when the motor starts. A rack is provided on the belt, meshing with the gear. When the gear rotates, it drives the rack, thereby moving the belt. Alternatively, an arc-shaped rack meshing with a lead screw structure, or a straight rack meshing with a lead screw structure, can be used to achieve the same function.

[0066] This embodiment uses the pressure acquisition module to collect external pressure and generate a pressure signal, which is then transmitted to the control module. The control module compares the pressure signal with a preset pressure signal, and generates and outputs a control signal to the power module based on the comparison result. The power module adjusts the strap according to the control signal, controlling its tension. The pressure acquisition module detects the applied pressure, i.e., the pressure exerted on the user. When the applied pressure does not match the preset pressure, it indicates that the strap is too tight or too loose. The control module compares the pressure signal with the preset pressure signal, generates and outputs a control signal to the power module based on the comparison result, and instructs the power module to automatically adjust the strap tension. This solves the technical problem of how to automatically adjust the strap tension according to the user's wearing habits.

[0067] Furthermore, in order to automatically retract and extend the tape only when the strap is in place, thus avoiding unnecessary system startup, the automatic tape retraction and extension system also includes a strap sensing module 400; the strap sensing module 400 is electrically connected to the control module 200.

[0068] The strap sensing module 400 is used to transmit a positioning signal to the control module 200 when it senses that the strap is in a preset position.

[0069] It should be noted that the strap sensing module can be a device that can sense the position of the strap and confirm whether the strap is in place.

[0070] In a practical implementation, two electrical contacts can be provided at the point where the strap sensing module contacts the strap, and a conductor, such as a bendable metal sheet, can be provided at the corresponding position on the strap. When the strap is not in the preset position, the two electrical contacts on the strap sensing module cannot conduct electricity; when the strap is in the preset position, the metal sheet on the strap contacts the two electrical contacts, and the two electrical contacts on the strap sensing module are electrically connected through the metal sheet. The connection status of these two electrical contacts can be used to confirm whether the strap is in place. When the strap is sensed to be in the preset position, a positioning signal is transmitted to the control module 200.

[0071] Accordingly, the control module 200 is used to compare the pressure value signal with a preset pressure signal when it receives the positioning signal, and generate and output a control signal to the power module 300 based on the comparison result.

[0072] Understandably, after the strap sensing module 400 is set up, in order to automatically retract and extend the strap only when it is in place, and to avoid the system starting up meaninglessly, the control module 200 will only perform automatic adjustment operations when it receives the positioning signal.

[0073] In this embodiment, the belt sensing module transmits a positioning signal to the control module when it senses the belt is in a preset position. Correspondingly, upon receiving the positioning signal, the control module compares the pressure value signal with a preset pressure signal, generates and outputs a control signal to the power module based on the comparison result. The control module only outputs a control signal when the belt sensing module detects the belt is in the preset position, causing the power module to move the belt and adjust its tension. Automatic belt winding and unwinding can only occur when the belt is in position, avoiding unnecessary system startup.

[0074] Based on the above embodiments, in order to enable users to control the winding and unwinding of the strap, a second embodiment of the automatic winding and unwinding strap system of the present invention is proposed.

[0075] In this embodiment, the automatic tape take-up and take-down system further includes a switch module 500; the switch module 500 is electrically connected to the control module 200.

[0076] The switch module 500 is used to transmit a switch signal to the control module when it receives an external control signal.

[0077] It is understood that the external control signal may be a signal generated by the user through operation of the switch module 500.

[0078] In a specific implementation, for example, the switch module 500 has a switch. When a user clicks the switch on the switch module 500, the switch module 500 transmits a first switch signal to the control module. When the user double-clicks the switch on the switch module 500, the switch module 500 transmits a second switch signal to the control module. When the user long-presses the switch on the switch module 500, the switch module 500 transmits a third switch signal to the control module. Alternatively, the switch on the switch module 500 may be a touchpad. When the user slides left on the touchpad, the switch module 500 transmits a first switch signal to the control module. When the user slides right on the touchpad, the switch module 500 transmits a second switch signal to the control module.

[0079] The control module 200 is further configured to generate and output a control signal to the power module based on the switch signal when the switch signal is received.

[0080] It is understood that the switch signal is generated based on the user's operation and can represent the user's intention. Therefore, the power module can be controlled according to the switch signal to adjust the belt.

[0081] In a specific implementation, for example, the switch on the switch module 500 is a touchpad. When the user slides left on the touchpad, the switch module 500 transmits a first switch signal to the control module. Upon receiving the first switch signal, the control module 200 outputs a control signal to the power module, driving the geared motor in the power module to rotate, causing the belt to move to the left. When the user slides right on the touchpad, the switch module 500 transmits a second switch signal to the control module. Upon receiving the second switch signal, the control module 200 outputs a control signal to the power module, driving the geared motor in the power module to rotate, causing the belt to move to the right.

[0082] In this embodiment, when the switch module receives an external control signal, it transmits a switch signal to the control module. Upon receiving the switch signal, the control module generates and outputs a control signal to the power module. Based on the user's operation, the power module is controlled, thereby controlling the automatic extension and retraction of the strap, allowing the user to control the strap's movement.

[0083] Furthermore, to facilitate user control of the cable retraction and extension, the switch module 500 includes: a power supply, a first switch, and a second switch; the first switch and the second switch are connected in parallel between the power supply and the control module.

[0084] Reference Figure 2 , Figure 2 This is a detailed structural diagram of the second embodiment of the automatic tape feeding and unloading system of the present invention.

[0085] like Figure 2 As shown, the pressure acquisition module 100 includes a pressure button 101 and a pressure sensor 102, and the control module 200 includes a first control board 201 and a second control board 202.

[0086] Pressure sensor 102 is installed at the bottom of the second control board 202. One end of pressure button 101 contacts the surface of pressure sensor 102, and the other end passes through the inner hole of the lower housing 700 and protrudes outward. The protruding part of pressure button 101 contacts external pressure, and pressure sensor 102 generates a pressure electrical signal to the second control board 202. The second control board 202 drives the geared motor to rotate forward or reverse according to the comparison between the external pressure and the preset pressure, thereby automatically adjusting the tension of the belt or strap.

[0087] Pin header 203, indicator light 204, and charging interface 205 are mounted on the second control board 202. The first control board 201 and the second control board 202 are electrically connected via pin header 203. Indicator light 204 is electrically connected to the second control board 202 and emits light according to signals sent by the control board 202, thereby conveying information to the user. Charging interface 205 is electrically connected to a power source (not shown in the figure) via the second control board 202 for charging the power source, which is a rechargeable battery, such as a lithium-ion battery or a nickel-zinc battery.

[0088] The switch module 500 includes a first switch and a second switch. In this embodiment, the positions of the first switch and the second switch are not limited. The first switch and the second switch are tactile switches and are mounted on the first control board 201.

[0089] The strap sensing module 400 includes a Hall sensor 401 and a magnet (not shown) fixed to the strap. The Hall sensor 401 is mounted on the first control board 201. When the strap is in place, the Hall sensor 401 is affected by the magnetic field generated by the magnet fixed to the strap, exhibiting a Hall effect, thereby transmitting a positioning signal to the first control board 201. The second control board 202 is fixed to the internal cavity of the upper shell 600 by screws 800.

[0090] The control module is further configured to receive a first electrical signal from the power source when the first switch is turned on, and generate and output a tightening signal to the power module based on the first electrical signal.

[0091] In a specific implementation, when the first switch is turned on, the pin of the first control board 201 connected to the first switch is connected to the power supply, and the first electrical signal of the power supply is received. The control module generates and outputs a tightening signal to the power module.

[0092] The power module is also used to tighten the strap when it receives the tightening signal.

[0093] In a specific implementation, when the power module receives the tightening signal, it drives the geared motor to automatically tighten the belt or strap.

[0094] The control module is further configured to receive a second electrical signal from the power source when the second switch is turned on, and generate and output a release signal to the power module based on the second electrical signal.

[0095] In a specific implementation, when the second switch is turned on, the pin of the first control board 201 connected to the second switch is connected to the power supply, receives the second electrical signal from the power supply, and the control module generates and outputs a release signal to the power module.

[0096] The power module is also used to loosen the strap when the loosening signal is received.

[0097] In a specific implementation, when the power module receives the relaxation signal, it drives the geared motor to automatically relax the belt or strap.

[0098] In this embodiment, the control module receives a first electrical signal from the power source when the first switch is on, generates and outputs a tightening signal to the power module based on the first electrical signal, and the power module tightens the strap upon receiving the tightening signal. When the second switch is on, the control module receives a second electrical signal from the power source, generates and outputs a loosening signal to the power module based on the second electrical signal, and the power module loosens the strap upon receiving the loosening signal. The automatic strap retraction and release controlled by the first and second switches facilitates user control over the strap's movement.

[0099] Furthermore, in order to quickly perform automatic belt winding and unwinding, the control module is also used to record the duration of the pressure value signal remaining constant. When the duration of the constant signal exceeds a preset duration, a fully adjusted signal is generated and output to the power module.

[0100] Understandably, during automatic pressure adjustment, only fine-tuning is typically performed. However, sometimes the initial position of the strap differs significantly from the optimal position, requiring the user to wait a considerable amount of time for the strap to move to the correct location, thus impacting the user experience. Therefore, if the pressure signal remains unchanged for more than a preset duration, the strap position can be adjusted significantly.

[0101] The power module is also used to adjust the strap according to the full adjustment signal, and to control the strap to be fully tightened or fully loosened.

[0102] In its implementation, the control module continuously monitors the pressure value. If the detected pressure is less than a preset pressure threshold within 5 seconds, it automatically tightens the belt or strap assembly to the first end of the rack. If the detected pressure is greater than the preset pressure threshold within 5 seconds, it automatically loosens the belt or strap assembly to the second end of the rack. It should be noted that during the complete tightening or loosening of the belt, if the detected pressure is close to the preset pressure threshold, the tightening or loosening can be stopped, and fine-tuning can be performed.

[0103] In this embodiment, the control module records the duration of the pressure signal remaining constant. When the duration of this constant duration exceeds a preset duration, a fully adjusted signal is generated and output to the power module. The power module adjusts the belt according to the fully adjusted signal, controlling the belt to fully tighten or loosen. When the automatic belt winding system is fine-tuned and the pressure does not change significantly for a long time, the drive motor rotates rapidly, thereby quickly performing automatic belt winding.

[0104] Based on the above embodiments, in one embodiment of the present invention, a sensing element is fixedly installed on the belt, and a sensor is installed inside the housing. The sensor is electrically connected to the control main board. The sensor is used to detect whether the sensing element on the belt has reached a preset position. The control main board controls the drive motor to work according to the feedback signal from the sensor. In this embodiment, when the user inserts the belt into the housing through the belt threading hole, when the sensor senses the sensing element on the belt, it can send a feedback signal to the control main board. The control main board can then control the drive motor to rotate according to the feedback signal, achieving the effect of automatic belt retraction. Specifically, the first sensor can be a Hall sensor, and the sensing element can be a magnet installed in the belt; of course, other capacitive proximity sensors (such as metal sensors) can also be used as sensors, and the sensing element can be a metal block, which can theoretically achieve the expected technical effect.

[0105] Of course, it is understandable that, based on the above implementation method, the housing can also be configured as an integral structure. The electric belt retraction structure includes a housing, a belt, a drive motor, a control board, and a battery. The drive motor, control board, and battery are installed inside the housing. The control board is electrically connected to the drive motor to control its operation. The battery provides power to the drive motor and control board. Two oppositely arranged belt-passing holes are formed on the housing. The belt passes through these holes and is fitted with a rack. A worm gear is mounted on the output shaft of the drive motor. The worm gear meshes with the rack, allowing the drive motor to drive the worm gear to rotate, thereby driving the rack to move linearly. The worm gear and rack are self-locking. This structure can also achieve basic control of the drive motor's forward and reverse rotation to control the belt's extension and retraction, and it also achieves a self-locking effect, preventing the belt from detaching from the housing due to external pulling.

[0106] Reference Figure 3 , Figure 3This is a flowchart illustrating the first embodiment of the automatic tape feeding and unloading method of the present invention.

[0107] The automatic tape feeding and take-up method is applied to the automatic tape feeding and take-up system described above; the automatic tape feeding and take-up method includes:

[0108] Step S10: The pressure acquisition module acquires external pressure to generate a pressure value signal and transmits the pressure value signal to the control module.

[0109] It should be noted that the pressure acquisition module can be a device capable of measuring pressure and providing remote electrical signals. Examples include strain gauge pressure sensors, piezoresistive pressure sensors, capacitive pressure sensors, piezoelectric pressure sensors, inductive pressure sensors, Hall effect pressure sensors, eddy current pressure sensors, and vibrating wire pressure sensors.

[0110] In a specific implementation, taking a capacitive pressure sensor as an example, the capacitive pressure sensor uses a circular metal thin film or a metal-plated thin film as one electrode of a capacitor. When the film deforms under pressure, the capacitance formed between the film and the fixed electrode changes. By measuring the capacitance value through a measuring circuit, an electrical signal that is related to the pressure magnitude can be output to the control module 200.

[0111] Step S20: The control module compares the pressure value signal with the preset pressure signal, and generates and outputs a control signal to the power module based on the comparison result.

[0112] It should be noted that the control module can be a controller, circuit board, or microcontroller with certain data processing capabilities.

[0113] In its implementation, the control module compares the pressure signal with a preset pressure signal, thereby comparing the pressure received by the pressure acquisition module with the preset pressure value. It is understood that the pressure received by the pressure acquisition module is difficult to maintain at a fixed value. Therefore, in practical applications, a preset pressure range can be used. The control module performs pressure range detection. When the detected pressure value is lower than the preset pressure range value, a control signal is output to the power module to automatically fine-tighten the belt assembly; when the detected pressure value is higher than the preset pressure range value, a control signal is output to the power module to automatically fine-tighten the belt assembly.

[0114] Step S30: The power module adjusts the belt according to the control signal to control the belt's extension and retraction.

[0115] It should be noted that the power module may be a device that is movably connected to the strap and capable of moving the strap.

[0116] In a practical implementation, a motor can be connected to a gear, which rotates when the motor starts. A rack is provided on the belt, meshing with the gear. When the gear rotates, it drives the rack, thereby moving the belt. Alternatively, an arc-shaped rack meshing with a lead screw structure, or a straight rack meshing with a lead screw structure, can be used to achieve the same function.

[0117] This embodiment uses the pressure acquisition module to collect external pressure and generate a pressure signal, which is then transmitted to the control module. The control module compares the pressure signal with a preset pressure signal, and generates and outputs a control signal to the power module based on the comparison result. The power module adjusts the strap according to the control signal, controlling its tension. The pressure acquisition module detects the applied pressure, i.e., the pressure exerted on the user. When the applied pressure does not match the preset pressure, it indicates that the strap is too tight or too loose. The control module compares the pressure signal with the preset pressure signal, generates and outputs a control signal to the power module based on the comparison result, and instructs the power module to automatically adjust the strap tension. This solves the technical problem of how to automatically adjust the strap tension according to the user's wearing habits.

[0118] Furthermore, to ensure automatic tape take-up and untake-up only occurs when the strap is in place, thus avoiding unnecessary system startup, the automatic tape take-up and untake-up system further includes a strap sensing module 400; the strap sensing module 400 is electrically connected to the control module 200. Before step S20, the method further includes:

[0119] Step S21: When the strap sensing module senses that the strap is in a preset position, it transmits a positioning signal to the control module.

[0120] It should be noted that the strap sensing module can be a device that can sense the position of the strap and confirm whether the strap is in place.

[0121] In a practical implementation, two electrical contacts can be provided at the point where the strap sensing module contacts the strap, and a conductor, such as a bendable metal sheet, can be provided at the corresponding position on the strap. When the strap is not in the preset position, the two electrical contacts on the strap sensing module cannot conduct electricity; when the strap is in the preset position, the metal sheet on the strap contacts the two electrical contacts, and the two electrical contacts on the strap sensing module are electrically connected through the metal sheet. The connection status of these two electrical contacts can be used to confirm whether the strap is in place. When the strap is sensed to be in the preset position, a positioning signal is transmitted to the control module 200.

[0122] Step S22: When the control module receives the positioning signal, it compares the pressure value signal with the preset pressure signal, generates and outputs a control signal to the power module based on the comparison result.

[0123] Understandably, after the strap sensing module 400 is set up, in order to automatically retract and extend the strap only when it is in place, and to avoid the system starting up meaninglessly, the control module 200 will only perform automatic adjustment operations when it receives the positioning signal.

[0124] In this embodiment, the belt sensing module transmits a positioning signal to the control module when it senses the belt is in a preset position. Correspondingly, upon receiving the positioning signal, the control module compares the pressure value signal with a preset pressure signal, generates and outputs a control signal to the power module based on the comparison result. The control module only outputs a control signal when the belt sensing module detects the belt is in the preset position, causing the power module to move the belt and adjust its tension. Automatic belt winding and unwinding can only occur when the belt is in position, avoiding unnecessary system startup.

[0125] Based on the above embodiments, a second embodiment of the automatic tape feeding and unloading method of the present invention is proposed.

[0126] Reference Figure 4 , Figure 4 This is a logic block diagram of the second embodiment of the automatic tape feeding and unloading method of the present invention.

[0127] The automatic tape take-up and take-up control method in this embodiment, and the logic control process of the automatic tape take-up and take-up system are as follows:

[0128] Step 1: The system determines the charging mode. When a charging device is connected, the system enters the charging mode, and the indicator light will show a breathing light when charging; when the battery is fully charged, the indicator light will show a solid green light.

[0129] Step 2: The system performs a low-power detection and enters sleep mode when the voltage is too low. In sleep mode, the system is in a low-power state. The system can be woken up in the following ways: a. Pressing the first switch and / or the second switch; b. Connecting the charging device; c. In automatic mode, the belt is threaded into the set position; d. In automatic mode, the pressure is greater than or less than the set threshold.

[0130] It should be noted that in this embodiment, the automatic tape rewinding system has a manual mode and an automatic mode. In manual mode, the system automatically rewinds and unwinds the tape based on the user's operation of the first and second switches. In automatic mode, the system automatically rewinds and unwinds the tape based on the pressure value sensed by the pressure acquisition module.

[0131] Step 3: The system determines the operating mode. If there is no operation for 5 seconds in standby mode, it enters sleep mode; if there is operation within 5 seconds in standby mode, the system enters standby or running mode.

[0132] Understandably, in order to conserve power in the automatic tape retraction system, it can enter sleep mode in standby mode to reduce system power consumption.

[0133] Step 4: The system determines the operating mode. The initial state of the system is manual mode. Press the first switch and the second switch simultaneously for 3 seconds to switch to automatic mode. The indicator light will flash white twice rapidly. Press the first switch and the second switch simultaneously for 3 seconds again to switch to manual mode. The indicator light will flash white three times rapidly.

[0134] The control process for the manual mode is as follows:

[0135] Step A5: When the system enters manual mode, the system performs button judgment. When the first switch is pressed for more than 0.5 seconds, the geared motor drives the belt assembly to tighten to the first end of the rack; when the first switch is pressed for less than 0.5 seconds, tightening stops when the first switch is released.

[0136] Step A6: When the system enters manual mode, when the second switch is pressed for more than 0.5 seconds, the geared motor drives the belt assembly to loosen to the second end of the rack; when the second switch is pressed for less than 0.5 seconds, the loosening stops when the second switch is released.

[0137] The control process for the automatic mode is as follows:

[0138] Step B5: Press the first switch and the second switch simultaneously to switch to automatic mode. The indicator light will flash white twice rapidly, and the system will perform belt assembly insertion detection. When the Hall element in the system detects the magnet of the belt assembly, the system will drive the motor to automatically tighten the belt assembly.

[0139] Step B6: In automatic mode, the system performs pressure range detection. If the detected pressure value is higher than the preset pressure threshold for 5 seconds, the system will automatically fine-tune and loosen the belt assembly.

[0140] Step B7: In automatic mode, when the second switch is pressed, the geared motor drives the belt assembly to loosen to the second end of the rack;
