Description

Technical Field

[0001] The utility model belongs to the technical field of motor assembly, and in particular relates to an assembly structure of a synchronous reluctance motor. Background Art

[0002] The synchronous reluctance motor is a special motor that combines the characteristics of a synchronous motor and a permanent magnet synchronous motor. It uses the principle of a synchronous motor to achieve torque control by controlling the relative size of electromagnetic excitation and permanent magnet excitation. The synchronous reluctance motor is very similar to a traditional induction motor in structure, but a reluctance element is added to the rotor, usually a reluctance cover or reluctance sleeve. In this way, when the motor is working, the reluctance element will generate a certain amount of magnetic resistance, thereby changing the magnetic field distribution, making the torque characteristics of the motor more flexible and adjustable. The synchronous reluctance motor has the advantages of higher efficiency, smaller torque fluctuation and a wider speed regulation range. Therefore, it is widely used in some applications that require precise control of torque and speed, such as industrial control systems, electric vehicles and robots.

[0003] Synchronous reluctance motors are widely used in industrial drive systems, such as driving conveyor belts, rotating machinery, fans and pumps on production lines. Synchronous reluctance motors play an important role in electric vehicles such as electric vehicles, hybrid vehicles and electric bicycles. Their high efficiency and adjustable speed characteristics make electric vehicles more advantageous in power output and energy utilization. Synchronous reluctance motors are also commonly used in household appliances such as washing machines, refrigerators, air conditioners, etc. They can usually provide higher torque and efficiency, and can achieve precise speed control to meet different work requirements. Synchronous reluctance motors are also widely used in various robots and automation systems to drive the joints and actuators of robots to achieve precise position control and motion execution. In general, the main function of synchronous reluctance motors is to provide efficient and controllable power output to meet the requirements of torque, speed and accuracy in different fields, thereby promoting the development and progress of various fields such as industry, transportation, family life and medical care. The problem with the above technology is that during use, the synchronous reluctance motor needs to be fixed and installed in a specific position through a base, multiple fixings and multiple connecting parts for driving use. However, the assembly process of the synchronous reluctance motor, the base and the multiple fixings requires a long time and effort, and the assembly process is relatively cumbersome, which is not convenient for users to quickly install and use the synchronous reluctance motor, thereby reducing the installation convenience of the synchronous reluctance motor. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model provides an assembly structure of a synchronous reluctance motor which can overcome the above problems or at least partially solve the above problems.

[0005] The utility model is implemented as follows: an assembly structure of a synchronous reluctance motor comprises a synchronous reluctance motor, a rubber block, a base and two connecting blocks, wherein the synchronous reluctance motor is located at the top of the rubber block and is fixedly connected to the top of the rubber block, the base is located at the bottom of the rubber block, the two connecting blocks are respectively located at the front side and the rear side of the rubber block and are fixedly connected to the surface of the rubber block, the surface of the connecting block is in contact with the inner cavity of the base, and the front side and the rear side of the inner cavity of the base are both provided with placement grooves; the inner cavity of the placement groove is provided with a positioning mechanism used in conjunction with the synchronous reluctance motor; the inner cavity of the placement groove is provided with a transmission mechanism used in conjunction with the positioning mechanism.

[0006] In order to improve the installation convenience of the synchronous reluctance motor, preferably, the positioning mechanism includes two positioning rods, two pull rods and four tension springs, the two positioning rods are respectively located on the left and right sides of the inner cavity of the placement slot, the two pull rods are respectively located at the opposite ends of the two positioning rods and are fixedly connected to the surfaces of the positioning rods, and the four tension springs are respectively located at the top and bottom on the opposite sides of the two pull rods and are fixedly connected to the surfaces of the pull rods. By setting up the positioning mechanism, the positioning rods can achieve the function of quickly fixing the synchronous reluctance motor through the mutual cooperation of the connecting block and the synchronous reluctance motor. After the synchronous reluctance motor is fixed to the base through the connecting block, the vibration amplitude generated during the use of the synchronous reluctance motor can also be diluted and damped through the rubber block to avoid affecting the connection stability.

[0007] In order to improve the mobility of the positioning mechanism, preferably, the transmission mechanism includes a servo motor, a turntable and two traction rods, the servo motor is located in the inner cavity of the placement slot, the turntable is located at the output end on the rear side of the servo motor and is fixedly connected to the output end of the servo motor, the two traction rods are respectively located on the left and right sides of the turntable and are fixedly connected to the surface of the turntable, the rear surface of the traction rod is in contact with the inner cavity of the pull rod, and by setting up the transmission mechanism, the servo motor can achieve the function of quickly driving the positioning rod to move through the pull rod through the mutual cooperation of the turntable and the traction rod, so as to achieve the situation that when the synchronous reluctance motor needs to be dismantled for maintenance, the synchronous reluctance motor cannot be separated from the fixed state.

[0008] In order to improve the moving stability of the transmission mechanism, preferably, the rear side of the turntable is movably connected with a support rod through a rotating shaft, and the bottom of the support rod is fixedly connected to the inner wall of the placement groove. By setting the support rod, the support rod can achieve the function of assisting the turntable to rotate stably through the connection with the rotating shaft of the turntable.

[0009] In order to improve the movement stability of the positioning mechanism, preferably, the top and bottom of the pull rod are fixedly connected with sliders, and the inner cavities of the two sliders are movably connected with a limit rod, and the side of the limit rod close to the inner wall of the placement groove is fixedly connected to the inner wall of the placement groove. By setting the slider and the limit rod, the limit rod can cooperate with the slider and the pull rod to guide the movement of the pull rod and the positioning rod, thereby avoiding shaking of the pull rod and the positioning rod during movement.

[0010] In order to improve the docking effect of the positioning rod, preferably, connecting holes are opened on the left and right sides of the inner cavity of the base, and positioning grooves are opened on the left and right sides of the connecting block. The opposite sides of the two positioning rods pass through the connecting holes and extend to the inner cavity of the positioning groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model starts the servo motor by arranging a synchronous reluctance motor, a rubber block, a base, a connecting block, a placement slot, a positioning mechanism and a transmission mechanism. The servo motor controls its own output end to rotate through a set threshold value, and the output end of the servo motor drives the turntable to rotate during the rotation, and the turntable drives the traction rod to rotate during the rotation. During the rotation, the traction rod contacts the inner wall of the pull rod and the inner wall of the pull rod is subjected to force. After the pull rods on both sides are subjected to force at the same time, the positioning rod is driven to move and the tension spring is stretched. After the positioning rod moves to a suitable position, the synchronous reluctance motor is docked with the base. During the docking process, the rubber block needs to be fitted with the top of the base and the connecting block needs to be inserted into the inner cavity of the base. After the docking is completed, the servo motor is started to reverse. When the output end of the servo motor is in the reversal process, it will simultaneously drive the turntable and the traction rod to rotate in the opposite direction. During the reverse rotation of the turntable and the traction rod, the pull rod will lose the force state. When the pull rod loses the force state, the tension of the tension spring contracts, and the positioning rod will be quickly driven through the pull rod to insert into the inner cavity of the positioning groove. After the positioning rod is inserted into the inner cavity of the positioning groove, the synchronous reluctance motor can be quickly installed through the cooperation of the connecting block and the rubber block.
