Technical Field
[0001] This utility model relates to the field of door opener technology, and in particular to a door opener equipped with a brushless motor. Background Technology
[0002] A door opener is an automated door control device used to automatically open and close doors to provide a convenient entry and exit experience, increase security, and offer easy-to-use door control options.
[0003] Existing technologies, such as Chinese Patent Publication No. CN221546720U, disclose a door opener equipped with a brushless motor, including a motor housing and a rack. The bottom of the motor housing has an adjustment mechanism, which includes a connecting plate. A support block is fixedly connected to the bottom of the connecting plate. A first balance bar is rotatably connected inside the support block. Second balance bars are provided at both ends of the first balance bar. Each end of the two second balance bars is slidably connected to a support leg via an inclined plane. The bottom of each of the four support legs is fixedly connected to a mounting foot. This invention, by setting up a motor housing, rack, and adjustment mechanism, allows the adjustment mechanism to be placed in the desired installation position when the motor housing needs to be installed. When the adjustment mechanism contacts the ground, the weight of the connecting plate causes the four support legs to press firmly against the ground, ensuring that all four support legs simultaneously contact the ground, enabling the motor housing to achieve self-balancing. Although this invention uses a more durable brushless motor as the drive method, it still integrates it with other more easily damaged components, making maintenance of these other components relatively inconvenient.
[0004] To address the inconvenience of maintenance and replacement of gate openers, most existing technologies use brushed motors as the drive mechanism. Even those few that use brushless motors haven't fully utilized their advantages. Because brushless motors offer reliable self-locking, high transmission efficiency, and long service life, it's more important to design features that facilitate maintenance or replacement of easily damaged components during use. This avoids the cumbersome process of operating the entire device, thus requiring improvement. Utility Model Content
[0005] The purpose of this utility model is to solve the shortcomings of the existing gate opener, which is inconvenient to repair and replace, and to propose a gate opener equipped with a brushless motor.
[0006] To achieve the above objectives, the present invention adopts the following technical solution: a door opener equipped with a brushless motor, comprising a motor housing, mounting holes, and a door opening device. The mounting holes are in multiple sets and are all located on the surface of the motor housing. The door opening device is disposed on the surface of the motor housing. The door opening device includes a drive assembly, a mounting assembly, and a disassembly assembly. The drive assembly includes a brushless motor, which is fixedly mounted on the inner surface of the motor housing. A coupling is fixedly mounted on the inner wall of the motor housing. One end of the coupling is fixedly connected to the output end of the brushless motor, and the other end of the coupling is fixedly mounted with a worm gear. A worm wheel is meshed with the surface of the worm gear, and a rotating shaft is fixedly connected to the surface of the worm wheel. A swing arm is fixedly connected to the surface of the rotating shaft. The number of swing arms is two sets, and they are symmetrically arranged.
[0007] Furthermore, the mounting assembly includes a mounting plate, which is fixedly connected to the surface of the motor housing. The surface of the mounting plate has a mounting groove, and a ratchet plate is slidably connected to the surface of the mounting groove. Both the mounting groove and the ratchet plate are positioned above the worm gear.
[0008] Furthermore, the end of the ratchet plate away from the mounting plate is fixedly connected to a mounting box, the worm gear is slidably connected to the inner wall of the mounting box, the worm wheel is disposed inside the mounting box, and the rotating shaft is rotatably connected to the inner wall of the mounting box.
[0009] Furthermore, a sliding groove is formed on the surface of the mounting groove, a spring is fixedly connected to the surface of the sliding groove, a pawl is fixedly connected to the other end of the spring, the pawl is slidably connected to the surface of the sliding groove, and the pawl is adapted to the ratchet plate.
[0010] Furthermore, the disassembly assembly includes a second slide groove, which is formed on the surface of the mounting plate. A second spring is fixedly connected to the surface of the second slide groove, and a button is fixedly connected to the other end of the second spring. The button is slidably connected to the surface of the second slide groove.
[0011] Furthermore, a limiting groove is formed inside the mounting plate, the limiting groove connects slide groove one and slide groove two, a central shaft is fixedly connected to the surface of the limiting groove, and a connecting rod is rotatably connected to the surface of the central shaft.
[0012] Furthermore, one end of the connecting rod is rotatably connected to the surface of the pawl, and the other end of the connecting rod is rotatably connected to the surface of the pressing block.
[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:
[0014] 1. In this utility model, by setting up a door opening device, the brushless motor is started, and the worm gear rotates under the action of the coupling, which in turn causes the worm wheel to drive the rotating shaft to rotate. The door opening operation is performed by using a swing arm. The brushless motor has the advantages of reliable self-locking, high transmission efficiency, and long service life. The swing arm is driven by the worm wheel and worm gear, which has a self-locking function. Since the brushless motor is not easily damaged, it is set up separately and fixedly installed. Other more easily damaged parts are placed inside the mounting box for easy replacement and maintenance. During installation, the ratchet plate on the mounting box is inserted into the mounting groove. During this process, the ratchet pawl is continuously squeezed to slide into the groove and compress the spring. When the ratchet plate... When fully slid into the mounting slot, the pawl engages with the ratchet plate under the rebound of spring one, preventing it from sliding outwards, thus completing the installation of the mounting box and the motor box. When it is necessary to disassemble the mounting box, simply press the button to slide it into slide groove two and compress spring two. Then, the connecting rod rotates along the central axis in the limit groove, thereby driving the pawl to slide into slide groove one and compress spring one, so that it no longer engages with the ratchet plate. This facilitates the removal of the mounting box for replacement or maintenance. By setting up an opening device, the brushless motor, which is not easily damaged, can be placed separately in the motor box and fixed, while other easily damaged parts can be installed on the motor box and are easy to install and disassemble, thus effectively improving the convenience of the equipment.

[0022] Please see Figure 1-5 This utility model provides a technical solution: a door opener equipped with a brushless motor, including a motor housing 1, mounting holes 2 and a door opening device 3. The mounting holes 2 are in multiple sets and are all opened on the surface of the motor housing 1. The door opening device 3 is disposed on the surface of the motor housing 1.
[0023] The specific setup and function of its door opening device 3 will be explained below.
[0024] In this embodiment: the door opening device 3 includes a drive assembly 31, an installation assembly 32, and a disassembly assembly 33. The drive assembly 31 includes a brushless motor 311, which is fixedly installed on the inner surface of the motor housing 1. A coupling 312 is fixedly installed on the inner wall of the motor housing 1. One end of the coupling 312 is fixedly connected to the output end of the brushless motor 311, and the other end of the coupling 312 is fixedly installed with a worm gear 313. A worm wheel 314 is meshed with the surface of the worm gear 313. A rotating shaft 315 is fixedly connected to the surface of the worm wheel 314. A swing arm 316 is fixedly connected to the surface of the rotating shaft 315. There are two sets of swing arms 316, which are symmetrically arranged.
[0025] The effect achieved by the above components is as follows: The motor box 1 is set up to set up the brushless motor 311 separately, making full use of the advantage that the brushless motor 311 is not easily damaged. The motor box 1 can be installed in the required position using the mounting hole 2. When the brushless motor 311 is started, the worm 313 is rotated under the action of the coupling 312, which in turn causes the worm wheel 314 to drive the rotating shaft 315 to rotate, and the swing arm 316 is used to open the door.
[0026] Specifically, the mounting assembly 32 includes a mounting plate 321, which is fixedly connected to the surface of the motor housing 1. The surface of the mounting plate 321 is provided with a mounting groove 322, and a ratchet plate 323 is slidably connected to the surface of the mounting groove 322. Both the mounting groove 322 and the ratchet plate 323 are located above the worm gear 313.
[0027] The effect achieved by the above components is as follows: the mounting box 324 is fixed to the motor box 1 by inserting the ratchet plate 323 into the mounting slot 322, which facilitates installation and disassembly. The mounting slot 322 and the ratchet plate 323 are set above the worm gear 313 to avoid the worm gear 313 from obstructing the mounting box 324 during installation and disassembly.
[0028] Specifically, the end of the ratchet plate 323 away from the mounting plate 321 is fixedly connected to the mounting box 324, the worm gear 313 is slidably connected to the inner wall of the mounting box 324, the worm wheel 314 is located inside the mounting box 324, and the rotating shaft 315 is rotatably connected to the inner wall of the mounting box 324.
[0029] The effect achieved by the above components is that other components, except for the brushless motor 311, are housed in the mounting box 324, which facilitates the repair or replacement of other easily damaged components without disassembling the motor box 1.
[0030] Specifically, the surface of the mounting groove 322 is provided with a sliding groove 325, and a spring 326 is fixedly connected to the surface of the sliding groove 325. The other end of the spring 326 is fixedly connected to a pawl 327. The pawl 327 is slidably connected to the surface of the sliding groove 325, and the pawl 327 is adapted to the ratchet plate 323.
[0031] The effect achieved by the above components is as follows: during installation, the ratchet plate 323 on the mounting box 324 is inserted into the mounting groove 322. During this process, the pawl 327 is continuously squeezed to make it slide into the slide groove 325 and compress the spring 326. When the ratchet plate 323 is completely slid into the mounting groove 322, the pawl 327 is locked by the spring 326 to prevent it from sliding outward, so that the mounting box 324 and the motor box 1 are installed.
[0032] Specifically, the disassembly component 33 includes a second slide groove 331, which is formed on the surface of the mounting plate 321. A second spring 332 is fixedly connected to the surface of the second slide groove 331, and a button 333 is fixedly connected to the other end of the second spring 332. The button 333 is slidably connected to the surface of the second slide groove 331.
[0033] The effect achieved by the above components is that pressing the button 333 will cause it to slide into the slide groove 331 and compress the spring 332. The spring 332 is provided to facilitate the rebound of the button 333 and to make pressing the button 333 require a certain amount of force to avoid accidental activation.
[0034] Specifically, a limiting groove 334 is provided inside the mounting plate 321. The limiting groove 334 connects the first slide 325 and the second slide 331. A central shaft 335 is fixedly connected to the surface of the limiting groove 334, and a connecting rod 336 is rotatably connected to the surface of the central shaft 335.
[0035] The effects achieved by the above components are as follows: the limiting groove 334 is set to connect the first slide groove 325 and the second slide groove 331 and limit the rotation angle of the connecting rod 336; the central shaft 335 is set to make the connecting rod 336 rotate along the central shaft 335.
[0036] Specifically, one end of the connecting rod 336 is rotatably connected to the surface of the pawl 327, and the other end of the connecting rod 336 is rotatably connected to the surface of the push block 333.
[0037] The effect achieved by the above components is as follows: after the push block 333 slides into the slide groove 331, it drives the connecting rod 336 to rotate along the central axis 335 in the limiting groove 334, thereby driving the pawl 327 to slide into the slide groove 325 and compress the spring 326, so that it no longer jams the ratchet plate 323, making it easy to remove the mounting box 324 for replacement or maintenance.
[0038] Working principle: By setting the door opening device 3, the brushless motor 311 is started. Under the action of the coupling 312, the worm gear 313 rotates, which in turn causes the worm wheel 314 to drive the rotating shaft 315 to rotate. The swing arm 316 is used to open the door. The brushless motor 311 has the advantages of reliable self-locking, high transmission efficiency, and long service life. The swing arm 316 is driven by the worm wheel 314 and the worm gear 313, which has a self-locking function. Since the brushless motor 311 is not easily damaged, it is set up and fixedly installed separately. Other more easily damaged parts are placed inside the mounting box 324 for easy replacement and maintenance. During installation, the ratchet plate 323 on the mounting box 324 is inserted into the mounting groove 322. During this process, the pawl 327 is continuously squeezed to slide into the slide groove 325 and compress the spring 326. When the ratchet plate 323 is fully inserted, the door opens. When fully slid into the mounting slot 322, the pawl 327, under the rebound action of the spring 326, locks the ratchet plate 323 to prevent it from sliding outward, thus completing the installation of the mounting box 324 and the motor box 1. When it is necessary to disassemble the mounting box 324, simply press the button 333 to slide it into the slide groove 331 and compress the spring 332. Then, the connecting rod 336 will rotate along the central axis 335 in the limiting groove 334, thereby driving the pawl 327 to slide into the slide groove 325 and compress the spring 326, so that it no longer locks the ratchet plate 323, making it easy to disassemble the mounting box 324 for replacement or maintenance. By setting the door opening device 3, the brushless motor 311, which is not easily damaged, is separately placed in the motor box 1 and fixed, while other easily damaged parts are installed on the motor box 1 and are easy to install and disassemble, which effectively improves the convenience of the equipment.
