Technical Field

[0001] This utility model relates to the field of motor technology, specifically to a decelerated DC brushless motor for a photovoltaic tracking bracket. Background Technology

[0002] Photovoltaic tracking brackets require a precise and reliable power drive system to achieve real-time angle adjustment. The integrated geared DC brushless motor integrates the reduction mechanism inside the motor, which simplifies the mechanical structure, improves the system's compactness and transmission efficiency, and provides more precise speed and torque control.

[0003] A search revealed a utility model patent with Chinese patent publication number CN222582195U, which discloses a DC brushless motor that is easy to maintain. The motor includes an adjustment plate, an adjustment rod fixedly connected to the inner cavity of the adjustment plate, an adjustment block slidably connected to the surface of the adjustment rod, an extension plate fixedly connected to the surface of the adjustment block, and the extension plate extending to the outer side of the adjustment plate from the side away from the adjustment block. Limiting blocks are fixedly connected to both the front and rear sides of the adjustment plate. Limiting through holes are formed on the surfaces of both the adjustment plate and the limiting blocks, and a limiting block is inserted into the inner cavity of the limiting through hole.

[0004] The aforementioned device secures the motor by using an adjustment plate and a fixing rod, making the fixing and disassembly process quicker. However, when in use, an additional structure is required to secure the adjustment plate, and the installation accuracy of this structure is difficult to determine, making it inconvenient to implement and leaving room for improvement.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 2 and Figure 3 As shown in this embodiment, a geared brushless DC motor for a photovoltaic tracking bracket includes a geared DC motor 1. The brushless DC motor consists of a stator, a rotor, a position sensor, and a controller. The reduction mechanism includes a gearbox and an output shaft. The operation process is as follows: the stator windings are energized to generate a rotating magnetic field, which interacts with the magnetic field of the rotor's permanent magnet to cause the rotor to rotate; the position sensor detects the rotor position and feeds it back to the controller, which then controls the energizing sequence of the windings to achieve commutation; the drive circuit adjusts the output to control the motor speed and direction; the motor shaft inputs power to the gearbox, and the gear set reduces speed and increases torque through the meshing of gears with different numbers of teeth. The bearing supports the gear shaft to ensure smooth operation. Finally, the output shaft outputs the decelerated power. The bottom of the decelerated DC motor 1 is coaxially fixed with a mounting plate 2. A connecting component 5 is installed on the outside of the mounting plate 2. The connecting component 5 includes several screws 503. The screws 503 are slidably inserted into the inside of the mounting plate 2 and are evenly distributed. A gear 504 is coaxially fixed at one end of the top of each screw 503. A mounting ring 501 is coaxially fixed on the top outer wall of the mounting plate 2. A gear ring 502 is rotatably connected inside the mounting ring 501 through a bearing. The gears 504 mesh with the gear ring 502.

[0023] The threaded portion of the screw 503 contacts the external threaded hole, pushing the gear ring 502 to rotate along the inside of the mounting ring 501. The gear ring 502 drives the gear 504 to rotate through meshing, and the gear 504 drives the screw 503 connected to it to rotate synchronously. These screws 503 will be screwed into the external threaded hole synchronously. Since the screws 503 move independently, they will not interfere with each other, so there will be no problem of movement obstruction. Then, these screws 503 press against the top wall of the mounting plate 2 to complete the fixation.

[0024] like Figure 1 and Figure 2 As shown, a retaining ring 4 is fixedly installed on the top outer wall of the gear ring 502 by bolts. The retaining ring 4 is located on top of several gears 504, which can prevent the screw and gears 504 from being unrestrained and detaching from the mounting plate 2.

[0025] like Figure 3 and Figure 4 As shown, several screws 503 are externally slidably fitted with a washer 3. The washer 3 consists of two rubber pads and a metal plate, with the metal plate located between the two rubber pads. It can attenuate the vibration energy of different frequency bands. Due to manufacturing errors or uneven external forces, the degree of descent of several screws 503 will have slight differences when the number of rotations is the same. The washer 3 is made of rubber material and can deform under pressure. The screw 503 at a lower position can continue to move after contacting the mounting plate 2, thereby ensuring that the screw 503 at a relatively higher position can also apply pressure to the mounting plate 2 and play its role.

[0026] like Figure 4 As shown, a positioning head 505 is provided at one end of the bottom of several screws 503. The positioning head 505 is inserted into the screw sleeve that matches the screw 503. The positioning head 505 at the end of the screw 503 is inserted into the external threaded hole, which can play a role in pre-positioning, ensuring that the mounting plate 2 is parallel to the installation part, so that the subsequent connection work can be carried out smoothly.

[0027] like Figure 1 and Figure 2 As shown, the housing of the geared DC motor 1 is made of titanium alloy, and the exterior of the geared DC motor 1 is coated with a ceramic coating, which can greatly improve the corrosion resistance of the motor.

[0028] like Figure 1 and Figure 2 As shown, the windings and stator core of the geared DC motor 1 are filled with high thermal conductivity silicone, which can reduce thermal resistance.

[0029] like Figure 3 As shown, screw 503 uses a self-locking bolt to ensure that it will not come out of the external threaded hole during use.

[0030] This utility model provides a geared integrated DC brushless motor for photovoltaic tracking brackets, and its specific working principle is as follows:

[0031] When the device is in operation, align the mounting plate 2 with the mounting location of the external equipment. Then, press the gear 504 to drive the screw 503 downwards. Subsequently, the positioning head 505 at the end of the screw 503 will insert into the external threaded hole, which can achieve a pre-positioning effect, ensuring that the mounting plate 2 remains parallel to the mounting location, so that the subsequent connection work can proceed smoothly. At this time, the threaded part of the screw 503 contacts the external threaded hole, pushing the gear ring 502 to rotate along the inside of the mounting ring 501. The gear ring 502 drives the gear 504 to rotate through meshing. The gear 504 drives the screw 503 connected to it to rotate synchronously. These screws 503 will be screwed into the external threaded hole simultaneously. In this process, since the screws 503 move independently and do not interfere with each other, there is no problem of movement obstruction. Then, these screws 503 press against the top wall of the mounting plate 2 to complete the fixation. Due to manufacturing errors or uneven external forces, the degree of descent of the screws 503 will vary slightly when the number of rotations is the same. The washer 3 is made of rubber material and can deform under pressure. The screw 503 at a lower position can continue to move after contacting the mounting plate 2, thus ensuring that the screw 503 at a relatively higher position can also apply pressure to the mounting plate 2 and play its role.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
