Description

Technical Field

[0001] This utility model relates to the technical field of motors, and particularly to a high-speed reciprocating short-stroke multi-track generating cascade array motor.

Background Art

[0002] Conventional motors have the following problems. Low conversion efficiency of conventional motors: In scenarios where high-speed reciprocating motion in a short stroke is required, general rotary motors need to use complex mechanical transmission mechanisms to convert into linear motion, resulting in significant energy loss and a remarkable decrease in efficiency during this process. High cost of linear motors: Existing linear motors have a complex structure and high manufacturing cost, and it is difficult to achieve motion control corresponding to multi-track generation. Limitations in miniaturized applications: In small devices such as robot joints and artificial hearts, conventional drive devices have a large volume and high power consumption, thus having limitations in applications. Under such a background, it has become an urgent task to realize a high-speed reciprocating short-stroke multi-track generating cascade array motor.

Summary of the Invention

[0003] The problem to be solved by this utility model is to eliminate the rotor structure found in conventional motors and utilize the interaction between multiple magnets and coils to achieve a reciprocating motion of short stroke, high speed, and multi-track generation. This device is particularly suitable for applications such as robot drive, facial expression imitation, artificial heart drive, vibration devices, aircraft wing extension and retraction, and ship paddle drive, where precise control and high-speed response are required.

[0004] As a technical means of this utility model, a high-speed reciprocating short-stroke multi-track generating cascade array motor is provided, which includes magnets, rectangular coils, guide rails, output ends, a base, and a support frame. There are multiple sets of the above-mentioned magnets, which are arranged front and back along the guide rail, and adjacent magnets have the same polarity. The first set of magnets is fixedly connected to the base. The rectangular coil is arranged between two rows of magnets. Each rectangular coil is supported as an integral structure by a support frame. The front edge of each rectangular coil is within the magnetic field of one magnet, and the corresponding rear edge is within the magnetic field of an adjacent magnet. (The rear edge can also be fixedly connected to the adjacent magnet without using electromagnetic connection.) The output end is fixedly connected to the rear edge of the rectangular coil in the final stage.

[0005] Furthermore, the magnet is composed of a permanent magnet or an electromagnet. Furthermore, the rectangular coil is formed of a copper wire or an aluminum wire. Furthermore, the support frame is composed of a non-conductive and lightweight rigid material. Furthermore, the output end can take the form of a robotic arm, a piston, a vibrator, etc. Furthermore, the guide rail is made of a lightweight and rigid material, and is composed of two or more sets up and down, or forms a pipe-shaped fully enclosed structure with a flexible material. Lubricity is ensured between the guide rail and the magnet. Furthermore, each rectangular coil is provided with positive and negative terminals for connecting to a power source.

[0006] Compared with the prior art, the advantages of this utility model are as follows. High-efficiency energy conversion: Through the coordinated operation of multiple sets of magnets and rectangular coils, electrical energy can be efficiently converted into mechanical energy, greatly improving the energy utilization rate. High-speed response: By the simultaneous operation of multiple sets of magnets and rectangular coils, high-speed responsiveness is achieved, enabling movement over a greater distance in a short time. It is suitable for scenarios requiring high-speed operation, such as the expansion and contraction of aircraft wings.

Multi-track generation: It can cope with complex motion patterns involving multiple track generations, realizing highly flexible movements such as the joint movements of robots and the imitation of facial expressions. Miniaturization compatibility: Since the structure is simple and compact, it is easy to mount on micro-devices such as artificial hearts and micro-robots. Low noise: Since it is based on linear motion, mechanical noise peculiar to rotary motors does not occur, and it has excellent quietness.

Modes for Carrying Out the Invention

[0008] Hereinafter, with reference to the drawings, specific embodiments of a high-speed reciprocating short-stroke multi-orbit generation cascade array motor according to the present utility model will be described in more detail. As shown in Figure 1, a high-speed reciprocating short-stroke multi-orbit generation cascade array motor according to the present utility model is composed of the following components. Magnet 1: A plurality of sets of permanent magnets 1 or electromagnets 1 are arranged back and forth along the guide rail 6. Adjacent magnets 1 in the front and back have the same polarity, forming a continuous magnetic field distribution. The first set of magnets 1 is fixed to the base. Coil: The rectangular coil 2 is formed by winding a plurality of conducting wires in layers. The front edge of each rectangular coil is within the magnetic field of one magnet 1, and the corresponding rear edge is within the magnetic field of an adjacent magnet 1. The rectangular coil 2 is supported as an integral structure by the support frame 6 and can transmit the input force. Lubricity is ensured between the rectangular coil 2 and the magnet 1. By using a high-conductivity material such as copper or aluminum for the material of the rectangular coil, energy loss is reduced. Guide rail 3: The guide rail 3 guides the magnet 1 along a predetermined orbit. Depending on the application, a lightweight hard material with low surface friction or a flexible material can be selected. Output end 4: It is fixedly connected to the rear edge of the rectangular coil 2 at the final stage and outputs mechanical motion to the outside. The output end 4 can take the form of a robotic arm, piston, vibrator, etc., and is designed according to the application. Base 5: It is a base that supports and fixes the overall structure and serves as the starting point of force. Support frame 6: It is a lightweight and high-rigidity rectangular frame that supports the rectangular coil 2 and reliably transmits the force applied to the front end to the rear end.

[0009] The operating principle of this utility model: Theoretical basis: 1. Ampere's force principle: The law regarding the force generated when a conductor through which current flows moves across magnetic field lines in a magnetic field. The magnitude of the force is proportional to the strength of the magnetic field and the value of the current, and the direction is determined by the direction of the magnetic field and the direction of the current, following Fleming's left-hand rule. 2. Action and reaction and relative motion: When a force acts between two objects, the other object moves relatively according to the reference object. Operating mechanism: The base 5 is fixed, and the first set of magnets 1 causes a linear motion in the energized rectangular coil 2 within the magnetic field. The energized rectangular coil 2 pushes the next magnet 1 in the same direction, and further that magnet 1 pushes out the next rectangular coil 2 in the same direction. Through this series of operations, electrical energy is converted into mechanical energy. By switching the direction of the current or the magnetic field, the direction of motion can also be reversed. In this way, motions of high speed, short stroke, reciprocating, and multi-orbit generation are realized. By arranging multiple units of this motor in parallel, a greater driving force can be obtained, and by giving different motion directions and amounts of motion to individual motors, motions involving multiple orbit generations are also possible.

[0010] A specific example of the implementation operation in this utility model is as follows. Forward motion: 1. When current is passed through the rectangular coil 2, the rectangular coil 2 starts to move under the action of electromagnetic force within the magnetic field. The direction of the force is determined by the direction of the magnetic field and the direction of the current, following Fleming's left-hand rule. 2. As shown in Fig. 1, the front edge of the rectangular coil 2 receives a thrust force in the right direction from the front magnet 1 and moves to the right including the rear edge via the support frame 6. 3. The rear edge of the rectangular coil 2 is originally subject to a leftward force by the rear magnet 1, but since a rightward force is transmitted from the front edge through the support frame 6 (the first set of magnets 1 is fixed), it can actually only move in the right direction and push the rear magnet 1 (or it is also possible to directly push it by fixedly connecting the rear edge and the magnet 1). 4. Subsequently, the rear magnet 1 further pushes the subsequent coil 2 to the right. 5. Such a series of operations continues, and finally the last coil 2 transmits a force to the output end 4, and the output end 4 moves to the right, thereby releasing electrical energy as mechanical output. Reverse movement: As shown in Fig. 1, by reversing the current direction or the magnetic field direction, it is possible to switch the movement direction to the left. Multi - track generation: By arranging multiple such motors in parallel, a greater driving force can be obtained. By giving different movement directions and momenta to individual motors, movement involving multiple - track generation is also possible.
