[0030] Preferred embodiment.

[0031] This embodiment provides a sliding door operator driven by a high-voltage brushless motor 210, including:

[0032] The main structure includes an installation body 100 and a door operator cover 110, wherein the door operator cover 110 is disposed at the upper end of the installation body 100;

[0033] A connecting structure is provided at the upper end of the mounting body 100. The connecting structure includes a high-voltage brushless motor 210, a motor spline 211, a worm gear 220, a spline sleeve 221, and a worm wheel 230. A reduction gearbox 200 is provided at the upper end of the mounting body 100. The high-voltage brushless motor 210 is located at the upper end of the reduction gearbox 200, and the motor spline 211 is located at the lower end of the high-voltage brushless motor 210. The worm gear 210... 20 is located below the high-voltage brushless motor 210, the spline sleeve 221 is located at the upper end of the worm 220, the motor spline 211 matches the spline sleeve 221, the worm wheel 230 is horizontally located at the rear side of the worm 220, the worm wheel 230 is provided with a worm wheel 240, the worm wheel 240 matches the worm 220, and the right end of the worm wheel 230 passes through the reduction gearbox 200 and is provided with a drive wheel 250;

[0034] A control board is disposed at the upper end of the gearbox 200, and the control board is used to control the high-voltage brushless motor 210.

[0035] Compared to traditional brushed DC motors, the 210 high-voltage brushless motor has lower friction losses due to the absence of brushes on the rotor, resulting in higher energy conversion efficiency, less noise, and less wear. Compared to traditional brushed sliding doors, it offers advantages such as higher efficiency, longer lifespan, and lower noise. Furthermore, compared to low-voltage brushless motors, high-voltage motors require less power supply and distribution equipment, resulting in lower circuit losses and greater energy efficiency, thus better meeting customer requirements. At the same output power, the current of a high-voltage motor is significantly lower than that of a low-voltage motor; at the same power, current and voltage are negatively correlated. Therefore, high-voltage motors can use smaller wire diameters in their windings. Consequently, the stator copper losses of high-voltage motors are also lower than those of low-voltage motors. For high-power motors, using low-voltage electricity requires thicker wires and larger stator slots, resulting in a larger stator core diameter and a larger overall motor size. For high-capacity motors, compared with low-voltage motors, high-voltage motors require less overall investment in power supply and distribution equipment, have lower line losses, and can save on electricity consumption.

[0036] Furthermore, the worm gear 230 has a first limiting groove 231 in its middle portion, and the worm wheel 240 matches the first limiting groove 231. A first limiting ring 271 is provided at the left end of the first limiting groove 231, matching the left end of the worm wheel 240. A second limiting ring 272 is provided at the right end of the first limiting groove 231, matching the right end of the worm wheel 240. The first limiting ring 271 and the second limiting ring 272 are used to confine the worm wheel 240 within the first limiting groove 231, ensuring the stability of the worm wheel 240, that is, ensuring the cooperation between the worm wheel 240 and the worm 220.

[0037] Furthermore, the left end of the worm gear 230 is provided with a first insertion hole 233, and the first insertion hole 233 is provided with a first release rod 261, a first release key 263 and a first spring 262. The first release rod 261 is located at the right end of the first insertion hole 233, the first spring 262 is located at the right end of the first insertion hole 233, and the first release key 263 is located between the first release rod 261 and the first spring 262. The middle part of the worm gear 230 is provided with a first release hole 232, and the first release key 263 matches the first release hole 232. The right end of the worm gear 240 is provided with a first release groove 241, and the bottom of the first release groove 241 is provided with a first fixing groove 242, which matches the first release key 263. The first release lever 261 pushes the first release key 263 to move to the right, so that the first release key 263 moves out of the first fixed groove 242 and into the first release groove 241, thereby preventing the worm gear 240 from driving the worm gear rod 230 to rotate when it rotates, and thus the first drive wheel 250 will not rotate, thus realizing the release of the sliding door operator.

[0038] Furthermore, the left end of the mounting body 100 is provided with a release support frame 140, and the left end of the release support frame 140 is hinged with a release wrench 150. The lower end of the release wrench 150 is provided with a cam portion 151, and the right end of the release support frame 140 is provided with a first through hole that matches the first insertion hole 233. The left end of the first release rod 261 passes through the first through hole and matches the cam portion 151. Rotating the release wrench 150 downwards causes the cam portion 151 to press the first release rod 261 to move to the right, thereby pushing the first release key 263 to move to the right.

[0039] Furthermore, the left end of the door operator cover 110 is provided with a first clearance opening 111, which matches the release wrench 150. The upper end of the release wrench 150 is provided with a release key 160, and the other end of the release key 160 is provided with a release twist plate 161, which matches the door operator cover 110. The release key 160 controls the rotation of the release twist plate 161, which can be hooked on the inside of the door operator cover 110, thereby restricting the rotation of the release wrench 150 and preventing the release wrench 150 from being accidentally opened.

[0040] Furthermore, the left end of the door operator cover 110 is provided with an outward-folding waterproof flange 112. The main structure includes a release sliding cover 120, and the inner side of the release sliding cover 120 is provided with a plurality of first limiting strips 121, which match the outward-folding waterproof flange 112. The release sliding cover 120 can move up and down along the first limiting strips 121, which serves to protect the release lever 150 and prevent the release lever 150 from being accidentally opened.

[0041] Furthermore, the main structure includes a motor cover 130, which is disposed at the upper end of the high-voltage brushless motor 210, and the control board is disposed at the upper end of the motor cover 130;

[0042] The control board includes a power supply circuit, a drive circuit, a remote control circuit, a digital tube display circuit, and a signal input / output circuit. The drive circuit, remote control circuit, digital tube display circuit, and signal input / output circuit are all electrically connected to the power supply circuit, and the remote control circuit, digital tube display circuit, and signal input / output circuit are all electrically connected to the drive circuit.

[0043] The control board's power supply circuit is a flyback switching circuit, providing three different DC voltages: 310V, 16V, and 12V. The 310V DC power drives the high-voltage brushless motor 210; the 16V DC power powers the motor driver board; and the 12V DC power drives the remaining circuits. For safety reasons, the 16V and 12V power supplies are isolated to prevent operators from accidentally touching the equipment and causing electric shock.

[0044] The drive circuit is controlled by an independent MCU chip. Through program algorithms, the MOSFETs are controlled to drive the high-voltage brushless motor 210, enabling high-torque slow start, forward and reverse rotation, fast and slow speed operation, and deceleration and stopping. The motor drive board also features overcurrent protection and provides motor speed feedback signals. The main control board provides direction and speed control signals via high-speed optocouplers and receives speed feedback signals from the motor drive board to control the drive board, thereby enabling the operation of the high-voltage brushless motor 210 sliding door.

[0045] The remote control circuit consists of a WIFI circuit and a 433.92MHz wireless remote control circuit. The WIFI circuit, in conjunction with a mobile app, enables remote control of the door opening and closing, as well as modification of basic parameters. The 433.92MHz wireless remote control circuit receives the wireless radio frequency signal from the remote control for short-range (30M) door opening and closing.

[0046] The digital tube display circuit serves as the control board's setting interface, allowing users to adjust parameters and achieve functions such as speed regulation of the sliding door, slow start and slow stop of the door, and resistance adjustment.

[0047] The signal input / output circuitry will be used to connect external devices. The main control board will provide a 3.6W 12V DC power supply for external devices. External devices include limit switches for positioning the door open / close; infrared sensors for protection; facial recognition; external buttons for opening and closing; and warning lights.

[0048] A control method for a sliding door operator driven by a high-voltage brushless motor 210 includes the following steps:

[0049] Step S1: Assemble the sliding door motor driven by the high-voltage brushless motor 210 and install it at the corresponding sliding door. At the same time, connect the limit switch for positioning the door opening and closing position, the infrared ground sensor for protection, the button for opening and closing the door, and the warning light for warning.

[0050] Step S2: The remote control circuit receives the control signal, and the drive circuit drives the high-voltage brushless motor 210 to achieve functions such as high torque slow start, forward and reverse rotation, fast and slow operation, and deceleration and stop. Combined with the signal input and output circuit connected to the external limit switch, infrared ground sensor and button signal input, the high-voltage brushless motor 210 slide door can be operated accurately.

[0051] Step S3: Slide the release cover 120, use the release key 160 to rotate the release twist 161, thereby unlocking the release wrench 150, flip the release wrench 150 so that the first release rod 261 pushes the first release key 263 out of the first fixing groove 242, thereby realizing the release control of the high-voltage brushless motor 210 sliding door.

[0052] In addition, the sliding door motors currently on the market are basically AC asynchronous motors, brushed DC motors, and low-voltage brushless DC motors. There are currently no high-voltage brushless DC motors used in sliding door applications.

[0053] High-voltage brushless DC motors, compared to AC asynchronous DC motors:

[0054] 1. It is easy to control and allows for more precise adjustment of the door's operating speed, resulting in smoother and more fluid door operation. 2. Its brushless operating speed (24 m / min) is faster than that of an AC asynchronous motor (12 m / min).

[0055] 3. Due to the absence of friction between the brushes and the commutator, high-voltage brushless circuits offer advantages such as longer lifespan, lower noise, and lower heat generation.

[0056] 4. High-voltage brushless DC motors are typically designed to achieve higher efficiency.

[0057] High-voltage brushless DC motors compared to low-voltage brushed DC motors:

[0058] 1. Able to adapt to high loads: High-voltage brushless motors can work stably under high load conditions, while low-voltage brushed motors may experience performance degradation under high loads.

[0059] 2. Due to the absence of friction between the brushes and the commutator, high-voltage brushless circuits have the advantages of longer lifespan, lower noise, and lower heat generation.

[0060] High-voltage brushless DC motors compared to low-voltage brushless DC motors:

[0061] 1. High power density: High-voltage motors can provide higher power output within the same volume, enabling high-voltage brushless motor sliding doors to drive heavier doors.

[0062] 2. Higher efficiency: Under high power conditions, the efficiency of high-voltage brushless motors will be higher.

[0063] 3. Fast response: High-voltage brushless DC motors can respond to changes in current and voltage more quickly, making them suitable for applications that require rapid start and stop, resulting in smoother operation and more sensitive response of sliding doors.

[0064] 4. Superior thermal management: Because the high-voltage motor generates less heat during operation, the sliding door can be opened and closed multiple times in a short period of time without causing a decline in the overall performance of the machine.

[0065] In summary, the high-voltage brushless motor used in this application has advantages such as more stable performance, lower noise, and longer lifespan compared with traditional sliding door motors, and achieves higher efficiency, representing a significant advancement.

[0066] It is worth mentioning that the technical features of external devices such as limiters, infrared ground sensors and buttons involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control methods and spatial arrangement of these technical features can be adopted by conventional choices in the field, and should not be regarded as the utility model point of this utility model patent. This utility model patent will not be further elaborated in detail.
