Description

Technical Field

[0001] This utility model relates to the field of wireless charging technology, specifically a wireless charging device for an electric door sensor signal transmitting module. Background Technology

[0002] Currently, electric gate sensor signal transmission modules generally use wired or radio frequency (RF) wireless transmission methods to transmit control commands to the motor operating system. Wired transmission relies on the laying and connection of physical lines, which presents problems such as complex construction and limited flexibility. While RF wireless transmission avoids physical wiring, it requires an internal battery to operate. This battery-powered mode has significant drawbacks in practical applications: First, the battery has limited energy and needs to be replaced periodically. Frequent maintenance not only increases labor and material costs, but also easily causes equipment downtime, affecting the continuous operating efficiency of the gate system. Secondly, batteries are prone to performance degradation or even failure in extreme temperature or humid environments, leading to signal transmission interruption and directly affecting the door's response accuracy and operational safety. In addition, issues such as battery aging and leakage may also cause circuit corrosion, further reducing the overall stability of the system.

[0003] From a long-term operation and maintenance perspective, the battery-dependent model of radio frequency solutions significantly increases the total lifecycle management cost and poses safety hazards—in emergencies, if the battery runs out and the door cannot be opened or closed normally, it may lead to dangerous situations such as personnel being stranded or passageways being blocked. At the same time, the environmental pressure of disposing of waste batteries also contradicts the concept of sustainable development.

[0004] Therefore, existing technologies urgently need to break through the dual dependence on wired media and consumable batteries, and achieve stable, reliable, maintenance-free, and efficient control command transmission that can adapt to complex environments by innovating the power supply mechanism and signal transmission architecture, thereby comprehensively improving the safety and economy of electric door systems. Utility Model Content

[0005] The purpose of this invention is to provide a wireless charging device for an electric door sensor signal transmission module to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wireless charging device for an electric door sensor signal transmitting module, comprising a wireless charging transmitting module, a wireless charging receiving module, a control unit, and a sensor signal transmitting module; The wireless charging transmitter module mounting bracket or pre-embedded structure is installed on the electric door mounting frame. The electric door mounting frame includes a horizontal beam above the door, a ground pre-embedded frame at the bottom of the door, or vertical frames on both sides of the door. The wireless charging transmitter module is connected to an external power supply system via a power cord, and then connected to the charging control module of the control unit via a control line to receive start and stop commands. The wireless charging receiver module is integrated into the sensor signal transmitting module and moves synchronously with the door. The input end of the wireless charging receiver module is non-contactly coupled to the wire charging transmitter through a coil, that is, through electromagnetic induction or magnetic resonance (when the door is stationary, the alignment deviation is ≤5mm). The output end is connected to the input end of the voltage regulator circuit through a wire. The voltage regulator circuit, located adjacent to the wireless charging receiver module, is situated on the internal circuit board of the sensor signal transmitter module. Its input side is directly connected to the output wire of the wireless charging receiver module, and its output side is connected to the power supply terminal of the sensor signal transmitter module to provide a stable DC voltage. The sensor signal transmitting module is fixed on the bottom beam plate on the lower side of the door. Its power supply end receives the adapter voltage output by the voltage regulator circuit, and the signal end is connected to the motor control system through the radio frequency link. The motor control system is independent of the charging device. The control unit is integrated into the main control box of the electric gate, or installed independently near the fixed frame; The control unit includes a position detection module and a charging control module, which are used to monitor the door's movement status in real time; The position detection module includes an infrared sensor, a limit switch, a magnetic sensor, etc., and is installed on the fixed frame on the same side as the wireless charging transmitter module. It transmits the door position status to the charging control module via signal. The charging control module and the position detection module share a circuit board. The charging control module receives the position stop signal from the position detection module, sends start and stop commands to the wireless charging transmitter module, and detects the voltage feedback signal from the wireless charging receiver module for full charge determination.

[0007] That is, the position detection module detects that the door is in position, then generates a stop signal, which is then transmitted to the charging control module to achieve position triggering; The charging control module activates the wireless charging transmitter module, which then wirelessly transmits power to the wireless charging receiver module to initiate charging. The wireless charging receiver module outputs current, which is then stepped down or filtered by a voltage regulator circuit. The sensor power supply end then obtains a stable voltage, thus performing power conversion. The control unit can feed back to the charging control module whether the voltage signal from the wireless charging receiver module reaches a threshold to determine whether to stop charging. Alternatively, a door start command from the motor system can interrupt the power supply to the wireless charging transmitter module.

[0008] Compared with the prior art, the beneficial effects of this utility model are: by setting a wireless charging transmitter module on the fixed structure of the electric door and connecting a wireless charging receiver module to the sensor signal transmitter module, when the door moves to the preset position and stops, the transmitter is triggered to transmit electrical energy to the receiver, thereby powering the sensor signal transmitter module. This eliminates the need for frequent battery replacements, reducing maintenance costs. Furthermore, by controlling the charging timing when the door stops, the charging efficiency and safety are improved, ensuring the stable operation of the electric door. Dual-channel power-off mechanism: voltage threshold trigger + door displacement priority power-off to prevent overcharging; The position detection module, limit switch / infrared sensor ensure that the charging end deviation is ≤5mm; High-voltage integration is achieved by directly connecting the power supply terminal of the sensor signal transmission module to the voltage regulator circuit.

[0016] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0017] Please see Figures 1-3 A wireless charging device for an electric door sensor signal transmitting module includes a wireless charging transmitting module 1, a wireless charging receiving module 2, a control unit 3, and a sensor signal transmitting module 4. The wireless charging transmitter module 1 is installed on the electric door frame by a fixed bracket or pre-embedded structure. The electric door frame includes a horizontal beam above the door, a ground pre-embedded frame at the bottom of the door, or vertical frames on both sides of the door. The wireless charging transmitter module 1 is connected to an external power supply system via a power cord, and then connected to the charging control module of the control unit 3 via a control line to receive start and stop commands; The wireless charging receiver module 2 is integrated inside the sensor signal transmitting module 4 housing and moves synchronously with the door 10. The input end of the wireless charging receiver module 2 is non-contactly coupled to the wire charging transmitter through a coil, that is, through electromagnetic induction or magnetic resonance (when the door is stationary, the alignment deviation is ≤5mm). The output end is connected to the input end of the voltage regulator circuit through a wire. The voltage regulator circuit is located on the internal circuit board of the sensor signal transmitting module 44, adjacent to the wireless charging receiver module 2. Its input side is directly connected to the output wire of the wireless charging receiver module 2, and its output side is connected to the power supply terminal of the sensor signal transmitting module 4 to provide a stable DC voltage. The sensor signal transmitting module 4 is fixed on the bottom beam 9 on the lower side of the door body 10. Its power supply end receives the adapter voltage output by the voltage regulator circuit, and its signal end is connected to the motor control system through the radio frequency link. The motor control system is independent of the charging device. Control unit 3 is integrated into the main control box of the electric gate, or can be installed independently near the fixed frame; The control unit 3 includes a position detection module and a charging control module, which are used to monitor the movement status of the door 10 in real time; The position detection module includes an infrared sensor, a limit switch, a magnetic sensor, etc., and is installed on the fixed frame and on the same side as the wireless charging transmitter module 1. It transmits the position status of the door 10 to the charging control module through a signal. The charging control module and the position detection module share the same circuit board. The control module receives the position stop signal from the position detection module, sends start and stop commands to the wireless charging transmitter module 1, and detects the voltage feedback signal from the wireless charging receiver module 2 for full charge determination.

[0018] That is, the position detection module detects that the door 10 is in position, then generates a stop signal, which is then transmitted to the charging control module to realize position triggering; The charging control module activates the wireless charging transmitter module 1, which then wirelessly transmits power to the wireless charging receiver module 2 to initiate charging. The wireless charging receiver module 2 outputs current, which is then stepped down or filtered by a voltage regulator circuit, and then the sensor power supply end obtains a stable voltage, i.e., power conversion is performed. The control unit 3 can feed back to the charging control module whether the voltage signal of the wireless charging receiver module 2 has reached the threshold, and determine whether to stop charging. Alternatively, the start command for door 10 comes from the motor system, interrupting the power supply to the wireless charging transmitter module 1.

[0019] In Embodiment 1 of this utility model, when this device is applied to a roller shutter electric door; The door 10 is charged when it falls and closes, at which time the wireless charging transmitter module 1 is located on the lower side; The wireless charging transmitter module 1 is embedded in the ground guide groove, corresponding to the position where the door 10 is fully lowered, and the surface is covered with a pressure-resistant and waterproof cover plate. The wireless charging receiver module 2 is fixed on the bottom beam 9 of the roller shutter door and integrates an obstacle detection sensor.

[0020] Triggering mechanism: The lower edge of the door 10 touches the ground, and the limit switch or infrared sensor detects that the bottom beam 9 has landed.

[0021] Operation process: As the door 10 descends, the roller shutter moves downward, and the bottom beam 9 contacts the ground, the limit switch is pressed to generate a signal indicating that the door has fallen to the designated position. The control unit 3 then activates the ground wireless charging transmitter module 1 to trigger charging. The wireless charging transmitter module 1 and the wireless charging receiver module 2 are perpendicularly close (with a distance ≤ 3cm). Magnetic resonance technology penetrates the cover plate to transmit electrical energy, enabling vertical charging. After charging for a specified time, the charging will automatically stop, and the door 10 rising command will trigger an immediate power cut-off.

[0022] Charging occurs when the device is raised, with the wireless charging transmitter module 1 positioned on the top. The wireless charging transmitter module 1 is installed on the upper door frame 8, corresponding to the fully retracted position of the roller shutter door, and is suspended downwards by means of brackets or other means.

[0023] The wireless charging receiver module 2 is located on the bottom beam 9 of the roller shutter door. When the door curtain is rolled up to its highest position, the bottom beam 9 is placed on the outside, and the magnetic sensor of the upper door frame 8 is triggered at the top of the door body 10 to detect that the curtain has been rolled up to the correct position.

[0024] Running process When the door 10 rises, the roller shutter rolls up to the fully open state. When the top magnetic sensor identifies that the metal parts of the curtain slats are ≤2cm, it generates a signal that the door has risen to the correct position. The wireless charging transmitter module 1 and the wireless charging receiver module 2 are horizontally aligned (deviation ≤5mm). Electromagnetic induction is used for high-efficiency power supply to charge the top. Power-off mechanism: The wireless charging receiver module 2 automatically stops when the voltage reaches the threshold; the power is cut off within 50ms after the door 10 is sent down.

[0025] In Embodiment 2 of this utility model, when this device is applied to a sliding door; The wireless charging transmitter module 1 is installed inside the fixed vertical frame on both sides of the door 10, corresponding to the position when the door 10 is fully closed, and is fixed to the frame by a metal bracket; the wireless charging receiver module 2 is embedded in the sensor signal transmitter module 4 on the side edge of the bottom beam 9, and moves up and down synchronously with the door 10. Position detection module: Infrared sensors are installed in pairs on both sides of the vertical frame at the same height as the sensor signal transmission module 4, and aligned with the edge position of the door 10 when it is closed.

[0026] The voltage regulator circuit is integrated on the internal circuit board of the sensor signal transmitting module 4, and the output line of the receiver is directly connected to its input.

[0027] The control unit 3 is located in the control box at the top of the door frame and is connected to the infrared sensor and the wireless charging transmitter module 1 via a cable. Operation process: When the door 10 is closed: the sliding door moves in the closing direction. When the edge of the bottom beam 9 reaches the vertical frames on both sides, the infrared sensor detects that the door 10 is blocking and continuously sends a signal. Trigger charging: After the door 10 comes to a standstill, if the obstruction continues for more than the set time (about 1-2 seconds), the control unit 3 determines "stop in position" and starts the wireless charging transmitter module 1 on the vertical frame.

[0028] Power transmission: The coil of the wireless charging transmitter module 1 is precisely aligned with the coil of the receiver end at the edge of the bottom beam 9 (deviation ≤ 5mm). Power is transmitted to the wireless charging receiver module 2 through electromagnetic induction. The current of the wireless charging receiver module 2 is converted into the sensor adaptation voltage by the voltage regulator circuit and directly supplied to the sensor signal transmitter module 4.

[0029] Charging terminates when the voltage of the sensor's built-in capacitor rises to the full charge threshold, or when the door 10 receives an opening command: Control unit 3 immediately cuts off the power supply to wireless charging transmitter module 1; The door 10 starts to move, and the wireless charging receiver module 2 leaves the alignment area.

[0030] In this technical solution, the power supply terminal can be directly connected to a power source or powered by a lithium battery, depending on the specific circumstances.

[0031] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
