Description

Technical Field

[0001] The invention relates to the technical field of motors, and in particular to a reciprocating magnetic suspension motor. Background Art

[0002] In the field of motor technology, the performance and structural design of the motor have always been the key points of research and development. The traditional single-head single-swing motor has a large vibration problem during operation because it only has a single drive output. This will not only have an adverse effect on the stability and service life of the motor itself, but in the application scenario, it may also cause a series of negative effects such as noise and interference with peripheral equipment; moreover, the single-head single-swing motor has a high working energy consumption and is not energy-saving enough.

[0003] To solve the vibration problem, the double-headed double-swing motor came into being. However, the existing double-headed double-swing motors mostly use the side leverage solution, and the connecting rod is set on the side of the swing rod. In order to achieve the normal operation of this structure, an additional rotating shaft is required on the swing seat, and a corresponding set of structural configurations is required on each side. This undoubtedly greatly increases the overall structural complexity of the motor, increases the number of parts, and greatly increases the difficulty of assembly, which in turn leads to high production costs and difficulty in effectively ensuring production efficiency.

[0004] With the development trend of pursuing high-efficiency, stable and low-cost motors, the market urgently needs an innovative motor design. Summary of the invention

[0005] In order to solve the above-mentioned technical problems, the present invention provides a reciprocating magnetic levitation motor, including a mounting seat, a stator coil assembly, a spring, an external bracket and at least two swing seats. The swing seat is spaced apart from the mounting seat, and the springs are placed at both ends. The stator coil assembly is mounted on the mounting seat, and the swing seat is provided with a magnet and a swing rod. After power is turned on, the swing seat is driven to swing, and the spring maintains the swing path. The external bracket is sleeved on the outside and fixed to the mounting seat. A connecting rod is arranged between the two swing rods, and its two ends rotate and slide with the swing rod, and are rotatably connected to the external bracket with the center as a fulcrum. When the motor is powered on, the two swing rods move in opposite directions to effectively offset the vibration. The swing rod has both power transmission and mutual leverage functions. Compared with traditional single-head single pendulum and side-leverage double-head double pendulum motors, this motor has fewer parts, simple structure, low cost, and convenient assembly, which greatly improves production efficiency.

[0006] The technical solution of the present invention is achieved in this way: A reciprocating magnetic levitation motor comprises a mounting seat, a stator coil assembly, a spring sheet, an external bracket and at least two swinging seats arranged at intervals, the swinging seat and the mounting seat are arranged at intervals up and down, the spring sheet is arranged between the swinging seat and the mounting seat, and the spring sheet is arranged at the left and right ends of the swinging seat and the mounting seat; the stator coil assembly is mounted on the mounting seat, each swinging seat is also provided with a magnet and a swing rod, at least one swing rod is configured as an output member of the motor, the stator coil assembly and the magnet are configured to energize the stator coil assembly to drive the swinging seat to swing relative to the mounting seat, and maintain the swing path under the action of the spring sheet, thereby driving the swing rod to move; the external bracket is sleeved outside the swinging seat, the mounting seat and the stator coil assembly and is fixedly connected to the mounting seat; a connecting rod is provided between the two swing rods, and the two ends of the connecting rod are rotated and slidably matched with the two swing rods; the connecting rod is rotatably connected to the external bracket, and a rotation fulcrum is formed at the center of the connecting rod, and the connecting rod rotates around the rotation fulcrum; the connecting rod is configured so that when the stator coil assembly is energized to drive the swing rod to swing, the two swing rods always move in different directions.

[0007] Through the unique structural design, the two swing arms swing in opposite directions to effectively offset vibration. The swing directions of the two swing arms are always different, which can effectively offset the vibration caused by the swing. At the same time, the swing arm has the dual functions of power transmission and mutual force leveraging, that is, the swing arm is used for power transmission and for swinging against each other to achieve force leveraging, killing two birds with one stone, significantly reducing the number of parts, simplifying the structure, reducing costs, improving assembly efficiency and production convenience, and achieving high production efficiency.

[0008] Of the two swing arms, users can choose to enable a single swing arm or two swing arms according to their specific needs; when only a single swing arm is enabled, only one swing arm serves as the output member of the motor and is used to connect external components (such as razor blades). At this time, the two swing arms have different lengths, and the swing arm serving as the output member is longer, thereby achieving a single-head double-pendulum solution; when two swing arms are enabled, the two swing arms have the same length and are both connected to external components, thereby achieving a double-head double-pendulum solution. This makes the motor more adaptable and provides more choices for customers.

[0009] Compared with a single-head single-swing motor, the spring clips in this solution act on the two swing seats separately, allowing the two swing seats to swing in opposite directions respectively, and realize linkage under the action of the connecting rod, so that the buffering force is greater during swinging, and the vibration is correspondingly reduced. At the same time, the swing frequency and instantaneous frequency are faster, which improves the work efficiency. Correspondingly, the driving current is smaller, which is more energy-saving and environmentally friendly, and it will also make the noise smaller, the user experience is better, and it can better adapt to the market and gain the favor of users.

[0010] Preferably, the spring piece is U-shaped, including two action parts, the upper ends of the two action parts each have an upper connecting part, and the two upper connecting parts are connected to the two swing seats respectively; the lower ends of the two action parts each have a lower connecting part, and the two lower connecting parts are connected together and connected to the mounting seat; there is a gap between the two action parts. The spring piece is integrated, but the two action parts are separated, and there is a gap between the two, so as to act on the two swing seats separately; the action parts are connected together by the lower connecting part. If the spring piece is not integrated, when the process does not reach a certain degree of precision during the injection molding of the spring piece and the mounting seat and the swing seat, the force of the magnets on the two swing seats will make the two swing seats close to each other or repel each other, so that the swing seat and the swing rod cannot be in the normal working position; the integrated spring piece below can provide the force to separate the two swing seats, making up for the problem of imprecise injection molding; and when the two separated spring pieces are slightly tilted during injection molding, it will also affect the normal operation, so the prefabricated integrated spring piece is better used in the double-swing magnetic suspension motor.

[0011] Preferably, injection holes are provided on both the upper connecting part and the lower connecting part, which is more conducive to the stable connection of the spring piece, the mounting seat and the swing seat during injection molding.

[0012] Preferably, the mounting seat, the swing seat and the spring piece are integrally formed; the swing seat is located above the mounting seat, and the spring piece is arranged in the up-down direction and connects the swing seat with the mounting seat. During production, the mounting seat, the swing seat and the spring piece are integrally injection molded, which facilitates the subsequent assembly of the motor and improves production efficiency.

[0013] Preferably, the two ends of the connecting rod are provided with sliding rotation grooves, and the two swinging rods are respectively inserted in the two sliding rotation grooves. When the two swinging rods swing, the swinging rods rotate and slide relative to the connecting rod. The swinging rod can not only rotate but also slide in the sliding rotation groove. When the swinging rod is in different swinging positions, the swinging rod is also in different positions in the sliding rotation groove, thereby preventing motion interference; when the swinging rod swings, it rotates relative to the connecting rod and drives the connecting rod to rotate around the rotation fulcrum, thereby realizing swinging force.

[0014] Preferably, the outer bracket is provided with a support, the connecting rod is provided with a socket, the support is inserted into the socket, and the connecting rod is rotatably connected to the outer bracket through the support and the socket. The cooperation between the support and the socket ensures smooth force transmission.

[0015] Preferably, a mounting rod is formed on the outer bracket, the mounting rod is located between the two swinging rods, and the mounting rod is arranged horizontally in the left-right direction; the support is protruded downward on the mounting rod. The arrangement direction of the mounting rod is the same as the swing direction of the two swinging rods, so it will not affect the swing of the swinging rod.

[0016] Preferably, the mounting rod and the outer bracket are integrally injection molded. The mounting rod and the outer bracket are made of hard plastic or other special materials, which are strong and can withstand the force transmitted by the connecting rod when rotating, ensure structural strength, and extend service life; the mounting rod and the outer bracket are integrally injection molded, which is also conducive to subsequent assembly and improves production efficiency.

[0017] Preferably, the outer bracket protrudes upward to form a mounting portion spaced apart from the left and right, and the two swinging rods are located between the two mounting portions; mounting blocks are sleeved on the two swinging rods, and springs are provided between the mounting blocks and the mounting portions, and a spring is provided on the left and right sides of each mounting block. The springs give the swinging rods elastic force to return to the middle after swinging, so that the swinging rods can quickly return to their original positions and move in another direction; the two swinging rods do not have to be connected to external components (such as razor blades), and customers can choose to enable a single swinging rod or two swinging rods according to their needs; when two swinging rods are enabled, the two swinging rods are of equal length and both protrude upward from the mounting block.

[0018] Preferably, the outer bracket is fixedly connected to the mounting base and the stator coil assembly by screws.

[0019] The design starting point, concept and beneficial effects of the present invention using the above technical solution are: Through the unique structural design, the two swing arms swing in opposite directions to effectively offset vibration. The swing directions of the two swing arms are always different, which can effectively offset the vibration caused by the swing. At the same time, the swing arm has the dual functions of power transmission and mutual force leveraging, that is, the swing arm is used for power transmission and for swinging against each other to achieve force leveraging, killing two birds with one stone, significantly reducing the number of parts, simplifying the structure, reducing costs, improving assembly efficiency and production convenience, and achieving high production efficiency.

[0020] Of the two swing arms, users can choose to enable a single swing arm or two swing arms according to their specific needs; when only a single swing arm is enabled, only one swing arm serves as the output member of the motor and is used to connect external components (such as razor blades). At this time, the two swing arms have different lengths, and the swing arm serving as the output member is longer, thereby achieving a single-head double-pendulum solution; when two swing arms are enabled, the two swing arms have the same length and are both connected to external components, thereby achieving a double-head double-pendulum solution. This makes the motor more adaptable and provides more choices for customers.

[0021] Compared with a single-head single-swing motor, the spring clips in this solution act on the two swing seats separately, allowing the two swing seats to swing in opposite directions respectively, and realize linkage under the action of the connecting rod, so that the buffering force is greater during swinging, and the vibration is correspondingly reduced. At the same time, the swing frequency and instantaneous frequency are faster, which improves the work efficiency. Correspondingly, the driving current is smaller, which is more energy-saving and environmentally friendly, and it will also make the noise smaller, the user experience is better, and it can better adapt to the market and gain the favor of users.

[0028] Through the unique structural design, the two swing rods 7 swing in opposite directions to effectively offset the vibration. The swing directions of the two swing rods 7 are always different, which can effectively offset the vibration caused by the swing. At the same time, the swing rod 7 has the dual functions of power transmission and mutual force leveraging, that is, the swing rod 7 is used for power transmission and for swinging against each other to achieve force leveraging, killing two birds with one stone, significantly reducing the number of parts, simplifying the structure, reducing costs, improving assembly efficiency and production convenience, and having high production efficiency.

[0029] Specifically, if Figure 1-3As shown in 5-7, the motor is a double-headed double-swing swing magnetic levitation motor, which is characterized in that it has two swing seats 5 that are independently arranged but related in force transmission, and each swing seat 5 is provided with a swing rod 7; in the prior art, such a motor requires at least four spring clips to connect the two swing seats with the mounting seat, and in the embodiment, the motor has two spring clips 3, which are respectively located at the left and right ends of the mounting seat 1 and the swing seat 5, the mounting seat 1 and the swing seat 5 are both block-shaped, and the mounting seat 1, the swing seat 5 and the spring clips 3 are integrally formed; the swing seat 5 is located above the mounting seat 1, and the spring clips 3 are arranged in the up and down direction and connect the swing seat 5 with The mounting seat 1 is connected, and the outer bracket 4 is fixedly connected with the mounting seat 1 and the stator coil assembly 2 by screws; during production, the mounting seat 1, the swing seat 5, and the spring piece 3 are integrally injection molded, which facilitates the subsequent assembly of the motor and improves production efficiency; after the mounting seat 1, the swing seat 5 and the two spring pieces 3 are integrally molded, they together constitute a U-shaped frame structure; a swing extension seat 51 is protruding upward from the middle part of each swing seat 5, and the swing extension seat 51 is inserted with the swing rod 7, and the swing seat 5 and the swing extension seat 51 are integrally molded; when the above-mentioned frame structure is pre-produced, the swing rod 7 is also installed on the swing extension seat 51.

[0030] Furthermore, if Figure 6 , 7 As shown, the spring piece 3 is U-shaped, including two action parts 31, the upper ends of the two action parts 31 are provided with upper connecting parts 32, and the two upper connecting parts 32 are respectively connected to the two swing seats 5; the lower ends of the two action parts 31 are provided with lower connecting parts 33, and the two lower connecting parts 33 are connected together and connected to the mounting seat 1; there is a gap 34 between the two action parts 31; the spring piece 3 is integrated, but the two action parts 31 are separated, and there is a gap 34 between the two, so as to act on the two swing seats 5 separately; the action parts 31 are connected together by the lower connecting parts 33. If the spring piece 3 is not integrated, when the spring piece 3 is injection molded with the mounting seat 1 and the swing seat 5, the process is not When a certain degree of precision is reached, the force of the magnets 6 on the two swing seats 5 will make the two swing seats 5 close together or repel each other, so that the swing seat 5 and the swing rod 7 cannot be in the normal working position; the integrated spring piece 3 below can provide force to separate the two swing seats 5, making up for the problem of imprecise injection molding; and during injection molding, when the two separated spring pieces 3 are slightly tilted, it will also affect the normal operation, so the prefabricated integrated spring piece 3 is better used in the double-swing magnetic levitation motor; in addition, injection holes 35 are opened on the upper connecting part 32 and the lower connecting part 33, which is more conducive to the stable connection of the spring piece 3, the mounting seat 1 and the swing seat 5 during injection molding.

[0031] like Figure 3 , 4As shown, the outer bracket 4 is roughly in an inverted U shape, and has a total of four mounting arms 41, which are distributed on the front and rear sides, and the mounting arms 41 on each side are spaced left and right. The outer bracket 4 is connected to the mounting seat 1 and the stator coil assembly 2 through the four mounting arms 41; the outer bracket 4 also includes a seat 42, and the four mounting arms 41 are arranged on the seat 42 in a downwardly extending manner. The seat 42 is provided with a window 421, and the swing rod 7 extends out of the outer bracket 4 in the window 421, so that the swing rod 7 can be connected to the moving part, thereby realizing the function of the device; the seat 42 is provided with mounting portions 422 spaced left and right on the left and right sides of the window 421, and the two swing rods 7 are located between the two mounting portions 422; the two swing rods 7 are sleeved with mounting blocks 9, and a spring 10 is provided between the mounting block 9 and the mounting portion 422, and a spring 10 is provided on the left and right sides of each mounting block 9; the spring 10 gives the swing rod 7 an elastic force to return to the middle after swinging, so that the swing rod 7 can quickly return to its position and move in another direction; as shown Figure 8 As shown, not all of the two swing arms 7 are connected to external components (such as razor blades), and customers can choose to enable a single swing arm 7 or two swing arms 7 according to their needs; when both swing arms 7 are enabled, the two swing arms 7 are of equal length and both protrude upward from the mounting block 9.

[0032] like Figure 2 , 5 As shown, the mounting seat 1 is provided with a left-right symmetrical stator coil fixing seat 11 between the two spring plates 3.

The pillar 43 is metal, and the mounting rod 44 and the outer bracket 4 are both hard plastic. The mounting rod 44 and the outer bracket 4 are integrally injection molded. The metal parts and the hard plastic are strong and can withstand the force transmitted by the connecting rod 8 when rotating, ensuring the structural strength and extending the service life.
