[0034] Preferred embodiments.

[0035] This embodiment provides a sliding door machine driven by a high-voltage brushless motor 210, comprising:

[0036] A main structure, the main structure comprising a mounting body 100 and a door machine shield 110, wherein the door machine shield 110 is disposed at the upper end of the mounting body 100;

[0037] The coupling structure is arranged at the upper end of the installation body 100, and the coupling structure includes a high-voltage brushless motor 210, a motor spline 211, a worm 220, a spline sleeve 221 and a worm gear 230. The upper end of the installation body 100 is provided with a reduction box 200, the high-voltage brushless motor 210 is arranged at the upper end of the reduction box 200, the motor spline 211 is arranged at the lower end of the high-voltage brushless motor 210, and the worm 220 is provided with a spline sleeve 221. 20 is arranged below the high-voltage brushless motor 210, the spline sleeve 221 is arranged at the upper end of the worm 220, the motor spline 211 matches the spline sleeve 221, the worm gear 230 is horizontally arranged at the rear side of the worm 220, the worm gear 230 is provided with a worm wheel 240, the worm wheel 240 matches the worm 220, and the right end of the worm gear 230 passes through the reduction box body 200 and is provided with a driving wheel 250;

[0038] A control board is disposed at the upper end of the reduction gearbox 200 , and is used to control the high-voltage brushless motor 210 .

[0039] Compared with the traditional DC brushless motor, the high-voltage brushless motor 210 has a small friction loss due to the lack of brushes and electric brushes on the rotor of the brushless motor, so the power conversion efficiency is high, the friction sound is small, and the wear is less. Compared with the traditional brushed sliding door, it has the advantages of high efficiency, long life, low noise, etc. Compared with the low-voltage brushless motor, the high-voltage brushless motor uses less power and distribution equipment, has small circuit loss, and can be more energy-saving, so as to better meet the requirements of customers. When the output power is the same, the current of the high-voltage motor is much smaller than that of the low-voltage motor. Under the same power, the current and voltage are negatively correlated. Therefore, the winding of the high-voltage motor can use a smaller wire diameter. Therefore, the stator copper loss of the high-voltage motor is also smaller than that of the low-voltage motor. For high-power motors, when using low-voltage electricity, due to the need for thicker wires, larger stator slots are required, so that the diameter of the stator core is made very large, and the overall volume of the motor will also be very large. For large-capacity motors, compared with low-voltage motors, high-voltage motors require less overall investment in power supply and distribution equipment, have less line loss, and can save a certain amount of electricity consumption.

[0040] Further, a first limiting groove 231 is provided in the middle of the worm gear 230, 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, and the first limiting ring 271 matches 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, and the second limiting ring 272 matches the right end of the worm wheel 240. The first limiting ring 271 and the second limiting ring 272 are used to limit the worm wheel 240 in the first limiting groove 231, to ensure the stability of the worm wheel 240, that is, to ensure the matching of the worm wheel 240 and the worm 220.

[0041] Furthermore, a first socket 233 is provided at the left end of the worm gear 230, and a first release rod 261, a first release key 263 and a first spring 262 are provided in the first socket 233, the first release rod 261 is arranged at the right end of the first socket 233, the first spring 262 is arranged at the right end of the first socket 233, the first release key 263 is arranged between the first release rod 261 and the first spring 262, a first release hole 232 is provided in the middle part of the worm gear 230, the first release key 263 matches the first release hole 232, and a first release groove 241 is provided at the right end of the worm wheel 240, and a first fixing groove 242 is provided at the bottom of the first release groove 241, and the first fixing groove 242 matches the first release key 263. The first release rod 261 pushes the first release key 263 to move to the right, so that the first release key 263 moves out of the first fixing groove 242 and into the first release groove 241, so that when the worm wheel 240 rotates, it cannot drive the worm wheel 230 to rotate, and then the first driving wheel 250 will not rotate, thereby achieving the release of the sliding door machine.

[0042] Further, a release support frame 140 is provided at the left end of the installation body 100, a release wrench 150 is hingedly provided at the left end of the release support frame 140, a cam portion 151 is provided at the lower end of the release wrench 150, a first through hole is provided at the right end of the release support frame 140, the first through hole matches the first plug hole 233, and the left end of the first release rod 261 passes through the first through hole and matches the cam portion 151. When the release wrench 150 is turned downward, the first release rod 261 can be pressed to move to the right through the cam portion 151, that is, the first release key 263 is pushed to move to the right.

[0043] Further, a first clearance opening 111 is provided at the left end of the door machine guard 110, and the first clearance opening 111 matches the release wrench 150. A release key 160 is provided at the upper end of the release wrench 150, and a release twist piece 161 is provided at the other end of the release key 160, and the release twist piece 161 matches the door machine guard 110. The release key 160 controls the rotation of the release twist piece 161, and the release twist piece 161 can be hung on the inner side of the door machine guard 110, thereby limiting the rotation of the release wrench 150 and preventing the release wrench 150 from being opened by mistake.

[0044] Furthermore, the left end of the door machine shield 110 is provided with an outward-turned waterproof edge 112, and the main structure includes a release slide cover 120, and a plurality of first limit strips 121 are provided on the inner side of the release slide cover 120, and the first limit strips 121 match the outward-turned waterproof edge 112. The release slide cover 120 can move up and down along the first limit strips 121, which plays a role in protecting the release wrench 150 and preventing the release wrench 150 from being opened by mistake.

[0045] Furthermore, the main structure includes a motor shield 130, the motor shield 130 is arranged at the upper end of the high-voltage brushless motor 210, and the control board is arranged at the upper end of the motor shield 130;

[0046] The control board includes a power supply circuit, a drive circuit, a remote control circuit, a digital tube display circuit and a signal input and output circuit. The drive circuit, remote control circuit, digital tube display circuit and signal input and output circuit are all electrically connected to the power supply circuit, and the remote control circuit, digital tube display circuit and signal input and output circuit are all electrically connected to the drive circuit.

[0047] The control board power supply circuit is a flyback switch circuit, which provides the control board with three different voltage values ​​of 310V, 16V, and 12V DC. 310V DC is used to drive the high-voltage brushless motor 210; 16V DC is used to drive the power supply driver board; and 12V DC is used to drive the remaining circuits. For safety reasons, both 16V and 12V are isolated power supplies to prevent operators from accidentally touching the equipment and causing the risk of electric shock.

[0048] The driving circuit is controlled by an independent MCU chip, which controls the MOS tube to conduct and drive the high-voltage brushless motor 210 through the program algorithm to realize functions such as large torque slow start, forward and reverse steering operation, fast and slow speed operation, and deceleration stop. The motor drive board also has overcurrent protection and provides motor speed feedback signal function. The main control board provides steering signals and speed control signals through high-speed optical couplers and receives speed feedback signals from the motor drive board to control the drive board, thereby realizing the operation of the high-voltage brushless motor 210 sliding door.

[0049] The remote control circuit is composed of WIFI circuit and 433.92MHZ wireless remote control circuit. The WIFI circuit will be combined with the mobile phone APP to realize remote control of door opening and closing and basic parameter modification. The 433.92MHZ wireless remote control circuit will receive the wireless radio frequency signal of the remote control to control the door opening and closing function at a short distance (30M).

[0050] The digital tube display circuit is the setting interface of the control panel, through which the user can adjust the parameters to achieve the speed adjustment of the sliding door, the slow start and stop of the door body, and the resistance adjustment function of the door body.

[0051] The signal input and output circuit will be used to connect external devices. The main control board will provide 3.6W 12V DC power for external devices. The external device has a limiter to locate the door opening and closing position; infrared ground sensor to protect; face recognition, external button to open and close the door; warning light to warn.

[0052] A control method for a sliding door machine driven by a high-voltage brushless motor 210 comprises the following steps:

[0053] Step S1: Assemble the sliding door machine driven by the high-voltage brushless motor 210 and install it at the corresponding sliding door. At the same time, connect an external limiter for locating the door opening and closing position, an infrared ground sensor for protection, a button for opening and closing the door, and a warning light for warning.

[0054] Step S2: The remote control circuit receives the control signal, and the driving circuit drives the high-voltage brushless motor 210 to realize functions such as large torque slow start, forward and reverse steering operation, fast and slow speed operation, and deceleration stop, and combines the signal input of the external limiter, infrared ground sensor and button connected to the signal input and output circuit to realize the precise operation of the high-voltage brushless motor 210 sliding door;

[0055] Step S3: Slide and release the sliding cover 120, use the release key 160 to rotate the release twist piece 161 to unlock 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, and realizes the release control of the high-voltage brushless motor 210 sliding door.

[0056] In addition, the sliding door machines 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 for sliding door applications.

[0057] Compared with AC asynchronous DC motor, high voltage brushless DC motor has:

[0058] 1. Easy to control, the door running speed can be adjusted more accurately to make the door run more smoothly. 2. The brushless running speed (24M / min) is faster than the AC asynchronous motor (12M / min)

[0059] 3. Since there is no friction between the brush and the commutator, the high-voltage brushless has the characteristics of longer life, less noise, and lower heat generation.

[0060] 4. High-voltage brushless DC motors are usually designed to achieve higher efficiency.

[0061] High voltage brushless DC motors compared to low voltage brushed DC motors:

[0062] 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.

[0063] 2. Since there is no friction between the brush and the commutator, the high-voltage brushless motor has the characteristics of longer life, lower noise and lower heat generation.

[0064] High voltage brushless DC motors compared to low voltage brushless DC motors:

[0065] 1. High power density: High voltage motor can provide higher power output in the same volume, so that high voltage brushless motor sliding door can drive heavier door.

[0066] 2. Higher efficiency: Under high power conditions, the efficiency of high-voltage brushless motors will be higher.

[0067] 3. Fast response: High-voltage brushless DC motors can respond to changes in current and voltage more quickly, and are suitable for applications that require fast starting and stopping, making the sliding door run smoother and more responsive.

[0068] 4. Better thermal management: Since 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 decrease in the performance of the entire machine.

[0069] To sum up, the high-voltage brushless motor used in this application has the advantages of more stable performance, lower noise, longer life, etc., and achieves higher efficiency, making significant progress compared with various traditional sliding door machines.
