Description

Technical Field

[0001] The utility model belongs to the technical field of motors and relates to a reed-type linear yaw motor structure. Background Art

[0002] Most traditional pendulum-type linear motors are of a single mover assembly structure. When the single-layer mover assembly swings left and right, due to the processing and assembly errors between the magnetic tiles and the mover assembly, the mass distribution of the mover is not completely symmetric about the swing center of the mover.

[0003] Secondly, the structure of the traditional pendulum-type linear motor is a rotary yaw structure, and the overall structure is relatively complex with high precision requirements. Especially during use, due to the assembly precision limitations between the shaft and the bearing, and between the bearing and the inner hole of the mover iron core, there is a certain deviation in the perpendicularity of the axis line to the horizontal plane of the mover assembly.

[0004] During the circumferential swing of the mover assembly, the swing angular acceleration continuously changes. Under the action of the moment of inertia, the rotating shaft inevitably generates large-amplitude vibrations in the tangential direction of the swing plane (this vibration is transmitted to the external housing through the support part, increasing the noise), as well as small radial vibrations perpendicular to the swing direction in the swing plane caused by the uneven mass or assembly error of the former, and the perpendicularity deviation of the latter and the fact that there is only one bearing supporting in the axial direction, resulting in insufficient axial stiffness of the bearing, which will also cause torsional vibrations perpendicular to the swing plane about the swing center of the mover. The increase in the vibration amount increases the noise and affects the user experience. Content of the Utility Model

[0011] And split intermediate grooves are formed on the two-sided swing arm brackets of the swing bracket. The swing arm brackets are separated into two swing parts that can move independently by the split intermediate grooves. Both ends of the swing bar are respectively installed on two opposite swing parts.

[0012] As a further solution of the present utility model: the swing arm bracket has a "冂"-shaped structure and is composed of a connecting piece connected to the central main body of the swing bracket, a reinforcing piece arranged in parallel with the connecting piece, and an installation piece connecting the connecting piece and the reinforcing piece together;

[0013] The installation piece is perpendicularly arranged with the connecting piece and the reinforcing piece. The end of the swing bar is fixedly installed on the installation piece, and the split intermediate groove extends from the connecting piece to the position of the reinforcing piece.

[0014] As a further solution of the present utility model: the swing bracket is a double-layer bracket structure and is composed of two sets of identical frame bodies stacked up and down, thereby forming a double-layer swing arm bracket. The end of the swing bar is connected and matched with the installation pieces of the two-layer swing arm brackets together.

[0015] As a further solution of the present utility model: an installation groove for installing the E-shaped iron core is formed in the installation position of the swing bracket. The E-shaped iron core is inserted into the installation groove from the lower end. And a limiting foot extending outward is formed at the bottom position of the E-shaped iron core 11. When the E-shaped iron core is inserted into the installation groove and is in place, the limiting foot will abut against the bottom of the swing bracket to achieve the limiting effect;

[0016] And a set of locking brackets for fixing the E-shaped iron core are also installed on the swing bracket. The upper end of the locking bracket is a planar structure and is pressed on the installation position of the swing bracket; a plurality of locking pieces are formed at the lower end of the locking bracket.

[0019] The beneficial effects of the utility model are as follows: the method of using lateral linear motion to drive the yaw work replaces the traditional circular swing working method, which makes the overall structure simpler, reduces the overall structural accuracy requirements, lowers the production cost, and can be more widely promoted and used; and a bidirectional mover structure is used to achieve the working effect of generating force and reaction force in the direction of swing inertia in a reverse motion manner, which greatly offsets the vibration in the working direction of movement, thereby reducing the noise transmitted from the casing. At the same time, the structural method of the double-group mover parts greatly increases the volume density of the working unit, and the torque output is greater, thereby achieving the effect of improving the working performance while simplifying the swing structure.

[0026] In the embodiments of the present utility model, unless otherwise clearly specified and defined, terms such as "installation", "connection", "linkage", "fixation" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0027] The present utility model provides. Please refer to Figures 1 to 3 , in the embodiments of the present utility model, a reed-type linear yaw motor structure includes: a swing bracket 2, a stator group 1 and a rotor group 3 mounted on the swing bracket 2;

[0028] The swing bracket 2 has a "U" - shaped structure. The central position of the swing bracket 2 is an installation position 21, and the stator group 1 is installed in the installation position 21; while the two ends of the swing bracket 2 are yaw arm brackets 22 with a reed - type structure, and the rotor group 3 is installed on the yaw arm brackets 22;

[0029] Among them: The stator group 1 includes: an E - shaped iron core 11 placed horizontally. The E - shaped iron core 11 is composed of two iron - core ends 111 and an iron - core middle part 112. The iron - core middle part 112 is connected to the tail ends of the iron - core ends 111 to form an iron - core magnetic circuit; winding coils 12 are arranged on both of the two iron - core ends 111. When the winding coils 12 are energized, the magnetic field generated by the winding coils 12 can be conducted from the iron - core middle part 112 to the two iron - core ends 111 of the E - shaped iron core 11 through the iron - core magnetic circuit; the magnetic poles of the two iron - core ends 111 in the E - shaped iron core 11 are the same, and the magnetic pole of the iron - core middle part 112 is opposite to that of the iron - core ends 111;

[0030] The rotor group 3 includes two groups of swing bars 31 arranged in parallel. The two ends of the swing bars 31 are respectively installed on the two yaw arm brackets 22 of the swing bracket 2; a magnetized magnetic sheet 32 is installed at the lower middle position of the swing bar 31. The magnetized magnetic sheet 32 is close to the E - shaped iron core 11, and the magnetization directions of the magnetized magnetic sheets 32 on the two groups of swing bars 31 are opposite;

[0031] Thus, under this structural arrangement, the armature magnetic field of the iron - core middle part 112 and the two iron - core ends 111 of the E - shaped iron core 11 and the excitation magnetic field of the magnetized magnetic sheet 32 interact synchronously;

[0032] Taking a certain instant as an example, when the two iron - core ends 111 of the E - shaped iron core 11 of the E - shaped iron core 11 are the N - poles of the armature reaction, the iron - core middle part 112 is the S - pole;

[0033] When the left side of the first set of magnetized magnetic pieces 32 is the S pole and the right side is the N pole, at this instant, according to the principle of attraction and repulsion of magnetic poles, the magnetized magnetic piece 32 will move to the left. Since the magnetization direction of the other set of magnetized magnetic pieces 32 is opposite to that of the first set, the other set of magnetized magnetic pieces 32 will move to the opposite right side. When the NS poles of the E-shaped iron core 11 switch, the two sets of magnetized magnetic pieces 32 will move to the other side;

[0034] On both sides of the swing bracket 2, split grooves 221 are formed on the swing arm brackets 22. The split grooves 221 divide the swing arm brackets 22 into two swing parts 222 that can move independently. The two swing parts 222 on the same side can achieve the effect of deforming in two different directions; both ends of the swing bar 31 are respectively installed on two opposite swing parts 222; the function of this structure is to make the vibrations of the two oscillators (swing bars 31) resonate with each other, and further convert the reaction forces of the two oscillators into the same-direction power of each other. At the same time, when the resistance of one oscillator increases, its own power can be transmitted to the oscillator with greater resistance through the elastic connecting ears, improving the utilization efficiency of energy.

[0035] Furthermore, the swing arm bracket 22 is not limited to being extended from the material of the swing bracket 2, and can also be a separately set component, such as an elastic connecting piece with a circular wire diameter, or a U-shaped structure or a maze-shaped structure with a flat wire diameter.

[0036] Therefore, during the process of switching the NS poles of the E-shaped iron core 11, the two sets of magnetized magnetic pieces 32 will respectively drive the two swing bars 31 to perform linear movement in opposite directions on the swing bracket 2. The center upper end position of the swing bar 31 is the assembly position of the transmission part. The swing part for outward output is sleeved on the assembly position, and the left and right swing output is realized by driving through the two swing bars 31.

[0037] In the above-mentioned embodiment, the pole changes of the iron core end 111 and the iron core middle 112 in the E-shaped iron core 11 are determined by the positive and negative circuits of the input winding coil 12; the swing amplitude of the swing bar 31 is determined by the frequency of the input current; the torque size of the swing bar 31 is determined by the magnitude of the input current. Therefore, during actual use, the staff adjusts the work according to the above principle to achieve the required technical effect.

[0038] Furthermore, the swing arm bracket 22 has a "冂"-shaped structure, which is composed of a connecting piece 223 connected to the central main body of the swing bracket 2, a reinforcing piece 224 arranged in parallel with the connecting piece 223, and a mounting piece 225 connecting the connecting piece 223 and the reinforcing piece 224 together;

[0039] The mounting piece 225 is arranged perpendicular to the connecting piece 223 and the reinforcing piece 224; during the assembly process, the swinging bar 31 is mounted through the mounting piece 225, and the end of the swinging bar 31 is fixedly mounted on the mounting piece 225 by screws;

[0040] Then, the structural strength of the yaw arm frame 22 is improved through the reinforcing piece 224. In order to ensure that the yaw arm frame 22 has sufficient deformation performance, the split intermediate groove 221 extends from the connecting piece 223 to the position of the reinforcing piece 224.

[0041] Furthermore, the swinging bracket 2 is a double-layer bracket structure, which is composed of two sets of identical frame bodies stacked up and down, thus forming a double-layer yaw arm frame 22. The end of the swinging bar 31 is connected and cooperated with the mounting piece 225 positions of the two-layer yaw arm frame 22; during the working process, the overall structural strength can be improved through the double-layer yaw arm frame 22, and the working life of the yaw arm frame 22 can be extended.

[0042] Furthermore, an installation groove 211 for installing the E-shaped iron core 11 is formed in the installation position 21 of the swinging bracket 2. The E-shaped iron core 11 is inserted into the installation groove 211 from the lower end. And, a limiting foot 113 extending outward is formed at the bottom position of the E-shaped iron core 11. When the E-shaped iron core 11 is loaded into the installation groove 211 and the E-shaped iron core 11 is assembled in place, the limiting foot 113 will abut against the bottom of the swinging bracket 2 to achieve the limiting effect;

[0043] And a locking bracket 23 for fixing the E-shaped iron core 11 is also installed on the swinging bracket 2. The upper end of the locking bracket 23 is a planar structure and is pressed on the installation position 21 of the swinging bracket 2; a plurality of locking pieces 232 are formed at the lower end of the locking bracket. During installation, the locking pieces 232 are bent into a "C" - shaped structure, so as to clamp the swinging bracket 2 and the limiting foot 113 together to achieve fixation.

[0044] Furthermore, a core base 13 is arranged at the lower ends of the two winding coils 12, and the two winding coils 12 are fixed together through the core base 13;

[0045] The core base 13 is formed with a limiting insertion post 132 extending downward and a pair of parallel elastic clamping pieces 131; corresponding slots 212 to the limiting insertion post 132 are arranged on both the swinging bracket 2 and the locking bracket. During the installation process, the limiting insertion post 132 is inserted into the slots 212, and the two elastic clamping pieces 131 are clamped at both ends of the swinging bracket 2, thus achieving installation and fixation.

[0046] And in order for the core base 13 to achieve the effect of positioning installation, the limiting insertion posts are arranged at both ends of the core base 13 for realizing the installation positioning work.
