Description

Technical Field

[0001] This utility model relates to the field of motor equipment technology, specifically to an integrated assembly structure of controller and motor. Background Technology

[0002] In the field of modern electric transportation, the design of electric surfboards and electric vehicles tends to be compact and lightweight, which makes the space for motor installation extremely small. In existing motor application solutions, the motor and controller are usually two independent components. The motor is responsible for converting electrical energy into mechanical energy to drive the equipment, while the controller is used to precisely control the operation of the motor.

[0003] However, this separate structure has obvious disadvantages in the limited installation space. First, the independent motor and controller need to occupy a certain space, which greatly limits the reasonable layout of other components and the optimization of the overall structure for electric surfboards and electric vehicles, which are already in short installation space.

[0004] Therefore, it is essential to design an integrated assembly structure for the controller and motor that is space-efficient and easy to maintain. Utility Model Content

[0005] The purpose of this invention is to provide an integrated assembly structure for the controller and motor to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an integrated assembly structure of controller and motor, including a housing, a controller base detachably mounted on one axial end of the housing, a plurality of conductive copper sleeves fixedly connected at equal intervals around the circumference of the controller base, a controller plate detachably connected to one end of the conductive copper sleeves away from the controller base, a first bearing end cover provided on one side of the controller plate, a motor provided on one side of the first bearing end cover, the motor including a stator core and a rotor core, the rotor core being disposed inside the stator core, a second bearing end cover provided on the side of the motor away from the first bearing end cover, a transmission shaft provided between the first bearing end cover, the rotor core and the second bearing end cover, bearings provided at both ends of the transmission shaft.

[0007] According to the above technical solution, a bearing washer is embedded in the first bearing end cover, the bearing on the side closer to the first bearing end cover is embedded in the bearing washer, and the bearing on the side farther away from the first bearing end cover is embedded in the second bearing end cover.

[0008] According to the above technical solution, the controller base is provided with a plurality of copper pillars, and conductive heads are provided on the copper pillars. The copper pillars pass through the controller board. The end of the conductive head away from the copper pillar is installed inside the first bearing end cover. The stator core is provided with at least three conductive pillars. The conductive pillars pass through the first bearing end cover and are coaxially aligned with the conductive heads. A motor wire is connected between the conductive pillars and the conductive heads.

[0009] According to the above technical solution, a speed reducer is connected to one end of the transmission shaft near the second bearing end cover, and an output shaft is provided at the output end of the speed reducer.

[0010] According to the above technical solution, a thrust end cover is connected to the outside of the housing, and the output shaft passes through the thrust end cover and is disposed outside the housing.

[0011] According to the above technical solution, the housing is provided with corresponding bolt connection holes for the controller base, the first bearing end cover, the second bearing end cover and the reducer, and the axes of each bolt connection hole are arranged parallel to each other.

[0012] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0013] (1) By setting up a controller base, controller board, conductive copper sleeve and first bearing end cover, the integrated design of controller and motor is realized. Compared with the traditional separate controller and motor, this integrated structure significantly reduces the volume of the overall device, saves a lot of installation space, and allows the equipment to be flexibly laid out in work scenarios with limited space.

[0020] To enable those skilled in the art to better understand the present invention, the solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0021] This utility model provides a technical solution: an integrated assembly structure of controller and motor, including a housing 10. A controller base 20 is detachably installed at one axial end of the housing 10. Several conductive copper sleeves 21 are fixedly connected at equal intervals around the circumference inside the housing 10. A controller plate 22 is detachably connected to the end of the conductive copper sleeves 21 away from the controller base 20. A first bearing end cover 30 is provided on one side of the controller plate 22. A motor 40 is provided on one side of the first bearing end cover 30. The motor 40 includes a stator core 41 and a rotor core 42. The rotor core 42 is located inside the stator core 41. A second bearing end cover 50 is provided on the side of the motor 40 away from the first bearing end cover 30. A transmission shaft 43 is provided between the first bearing end cover 30, the rotor core 42, and the second bearing end cover 50. Bearings 44 are provided at both ends of the transmission shaft 43.

[0022] This technical solution achieves a compact and reasonable integrated layout of the controller board 22 and the motor 40. The housing 10 provides a stable support and protective space for the entire device. The controller base 20 can be detachably installed at one end of the housing 10, which facilitates the maintenance or replacement of related components of the controller board 22 in the future. The conductive copper sleeves 21 are evenly distributed on the controller base 20, which stably connects the controller base 20 and the controller board 22, which can transmit current and ensure the stability of the structure.

[0023] Furthermore, a bearing washer 31 is embedded in the first bearing end cover 30, the bearing 44 on the side closer to the first bearing end cover 30 is embedded inside the bearing washer 31, and the bearing 44 on the side farther away from the first bearing end cover 30 is embedded inside the second bearing end cover 50.

[0024] Through this technical solution, the bearing washer 31 provides precise positioning and additional cushioning for the bearing 44 on the side close to the first bearing end cover 30, reducing the shaking caused by uneven force on the bearing 44 during operation, and ensuring that the rotor of the motor 40 remains stable during high-speed rotation.

[0025] Furthermore, the controller base 20 is provided with several copper pillars 23, and conductive heads 24 are provided on the copper pillars 23. The copper pillars 23 pass through the controller board 22. The end of the conductive head 24 away from the copper pillar 23 is installed inside the first bearing end cover 30. The stator core 41 is provided with at least three conductive pillars 45. The conductive pillars 45 pass through the first bearing end cover 30 and are coaxially aligned with the conductive heads 24. A motor wire is connected between the conductive pillars 45 and the conductive heads 24.

[0026] Through this technical solution, the current is transmitted from the controller base 20 to the conductive head 24 via the copper column 23, and then efficiently and stably transmitted from the conductive head 24 to the conductive column 45 via the motor wire, and then delivered to the stator core 41, thereby generating a rotating magnetic field and driving the rotor core 42 to rotate synchronously.

[0027] Furthermore, a reducer 60 is connected to one end of the drive shaft 43 near the second bearing end cover 50, and an output shaft 61 is provided at the output end of the reducer 60;

[0028] Through this technical solution, the motor 40 drives the transmission shaft 43 to rotate at high speed, and the reducer 60 adjusts the speed and torque input to the transmission shaft 43 to adapt to the speed and torque, and outputs the adjusted power through the output shaft 61.

[0029] Furthermore, a thrust end cover 11 is connected to the outside of the housing 10, and the output shaft 61 passes through the thrust end cover 11 and is disposed outside the housing 10.

[0030] With this technical solution, when the device is working, the output shaft 61 transmits power to the outside, and the thrust end cover 11 prevents the output shaft 61 from shaking, ensuring the stable operation of the output shaft 61.

[0031] Furthermore, the housing 10 is provided with corresponding bolt connection holes 12 for the controller base 20, the first bearing end cover 30, the second bearing end cover 50 and the reducer 60, and the axes of each bolt connection hole 12 are arranged parallel to each other;

[0032] With this technical solution, workers can quickly and accurately locate the positions of each component and complete the installation based on the parallel bolt connection holes 12, improving assembly efficiency. Moreover, during device maintenance and repair, each component can be easily disassembled, facilitating internal maintenance and inspection.

[0033] Working principle: When the equipment is running, the power supply is connected to the controller base 20, and the current is transmitted to the controller board 22 through the conductive copper sleeve 21. The controller board 22 precisely controls the current according to the preset program. The processed current is conducted to the conductive head 24 through the copper column 23. The conductive head 24 transmits the current to the conductive column 45 through the motor wire, and then to the stator core 41, thereby generating a rotating magnetic field, driving the rotor core 42 to rotate synchronously, and then driving the transmission shaft 43 to rotate. The bearings 44 and bearing washers 31 at both ends of the transmission shaft 43 ensure smooth rotation and reduce vibration and wear. The reducer 60 adapts the speed and torque input to the transmission shaft 43 and outputs the adjusted power through the output shaft 61.
