[0001] This application relates to the technical field of linear motors, and particularly to reciprocating magnetic levitation linear motors.

Background Art

[0002] A reciprocating magnetic levitation linear motor, also called a linear motor, is mainly composed of a movable assembly (movable element) including a permanent magnet and a driving assembly (stator) including an electromagnet formed by winding a coil around an iron core. There is a certain gap between the permanent magnet and the iron core coil. The permanent magnet of the reciprocating linear motor reciprocates relative to the iron core coil at a certain frequency. In that case, in order to ensure the gap between the permanent magnet and the iron core, support by an elastic support mechanism is necessary. Also, this elastic support mechanism can provide an elastic restoring force for the reciprocating motion of the permanent magnet.

[0003] In related art linear motors, this elastic support mechanism is provided as an elastic piece, with one end fixed to the permanent magnet and the other end directly welded to the base of the bracket or the housing. On the other hand, when directly welding the elastic piece to the base or the housing, its metal properties are affected, so the vibration frequency of the elastic piece is affected, and the consistency between the natural frequency of the elastic piece and the permanent magnet and the frequency of the change in the current direction becomes low. Furthermore, the accuracy and efficiency of the reciprocating motion of the motor are affected.

[0030] This invention proposes a reciprocating magnetic levitation linear motor.

[0031] In an embodiment of the present invention, referring to Figures 1 to 4, the reciprocating magnetic levitation linear motor 10 includes a bracket 100, two sets of elastic support modules 200, a drive assembly 300, and a movable assembly 400 that levitates above the drive assembly 300. The drive assembly 300 is attached to the bracket 100 so as to move the movable assembly 400 back and forth in a predetermined direction by electromagnetic action. Both ends of the movable assembly 100 in the predetermined direction are connected via one set of elastic support modules 200. Connected to the racket 100, the elastic support module 200 includes a leaf spring elastic piece 210, an adapter assembly 220, and a first connecting member 230. The leaf spring elastic piece 210 includes a first connecting end 211 and a second connecting end 212, the first connecting end 211 being fixedly connected to the movable assembly 400, the first connecting member 230 passing through the second connecting end 212 and the adapter assembly 220 and fixing the leaf spring elastic piece to the bracket 100 via the adapter assembly 200.

[0032] In this embodiment, the bracket 100 is the main body of the entire reciprocating magnetic levitation linear motor 10, and the bracket 100 enables the mounting of the drive assembly 300 and the like. The bracket 100 may include only the base 120, in which case both the drive assembly 300 and the adapter assembly 220 are fixed to the base 120. Alternatively, the bracket 100 may include only the housing 110, in which case both the drive assembly 300 and the adapter assembly 220 are fixed to the housing 110. Furthermore, the bracket 100 may include both the base 120 and the housing 120, in which case the drive assembly 300 is fixed to the base 120, and the adapter assembly 220 is fixed to either the base 120 or the housing 110.

[0033] The movable assembly 400 may specifically include a permanent magnet and a magnet mounting base 410, the permanent magnet being fixed to the magnet mounting base 410, and both ends of the magnet mounting base 410 being connected to a bracket 100 via a set of elastic support modules 200. The drive assembly 300 may specifically include a core, a bobbin, and a coil, the coil being wound around the bobbin and attached to the core via the bobbin. This core may be a U-shaped core, an E-shaped core, etc., and is not specifically limited herein, and different types of cores can be selected according to actual needs. Only one set of drive assembly 300 may be provided, in which case only one set of movable assembly 400 may be provided, or two sets may be provided. If two sets of movable assembly 400 are provided, the corresponding magnetic poles of the permanent magnets in the two sets of movable assembly 400 are reversed. Thus, this one set of drive assembly 300 can simultaneously drive the two sets of movable assembly 400 to reciprocate in opposite directions. Of course, two or more sets of drive assemblies 300 may be provided. If two sets of drive assemblies 300 are provided, two sets of movable assemblies 400 are also provided, and the movable assemblies 400 of each set are installed above the drive assemblies. In this way, the two sets of drive assemblies 300 drive the corresponding drive assemblies 300 to reciprocate in opposite directions. The specific number of drive assemblies 300 and movable assemblies 400 is not limited in this specification and can be selected and designed according to the specific type of reciprocating magnetic levitation linear motor 10.

[0034] In embodiments of the present invention, when directional indications (e.g., up, down, left, right, front, back, etc.) are used, it should be explained that these directional indications are used solely to describe the relative positional relationships and motions between the components in a particular orientation, and that if the particular orientation changes, the directional indications will also change accordingly. Both ends of the movable assembly 400 are connected to the bracket 100 via a set of elastic support modules 200, which levitate the movable assembly 400 above the drive assembly 300. When a current whose direction alternates between forward and reverse is passed through the coil of the drive assembly 300, the drive assembly 300 becomes an electromagnet, and through the magnetic induction action between this electromagnet and the permanent magnet, and the elastic restoring action of the two elastic support modules 200, the drive assembly 300 drives the movable assembly 400 to reciprocate in a predetermined direction. In actual use, by attaching the cutter head assembly to the magnet mounting seat 410 of the movable assembly 400, the reciprocating magnetic levitation linear motor 10 can quickly move the movable blade of the electric shearing device back and forth relative to the fixed blade, or move the two movable blades of the electric shearing device back and forth in opposite directions, thereby cutting hair.

[0035] The leaf spring elastic piece 210 is specifically a plate-shaped structure having a certain elasticity, and sheet metal parts are usually used for the leaf spring elastic piece 210. Each set of elastic support modules 200 may include several leaf spring elastic pieces 210; for example, each set of elastic support modules 200 may include only one leaf spring elastic piece 210, or it may include two or more leaf spring elastic pieces 210 stacked or spaced apart. The number of leaf spring elastic pieces 210 can be selected and designed according to the actual needs and is not specifically limited here. The shape of the leaf spring elastic piece 210 can be various, such as mosquito coil-shaped, racetrack spiral-shaped, strip-shaped, frame-shaped, etc., as long as the leaf spring elastic piece 210 can stably support the movable assembly 400 on the support 100, and the movable assembly 400 reciprocates in a predetermined direction while the leaf spring elastic piece 210 provides an elastic restoring force in the opposite direction.

[0036] To improve structural strength, metal materials are typically used for the adapter assembly 220 and the bracket 100. The first connecting end 211 of the leaf spring elastic piece 210 and the movable assembly 400 can also be fixedly connected by welding, fitting and then welding, or other methods. The structure of the adapter assembly 220 can be various. For example, the adapter assembly 220 can be a block-shaped structure, a plate-shaped structure, etc. Specifically, the first connecting member 230 can be a rivet, screw, bolt, etc. Specifically, through holes are made in both the second connecting end 212 of the leaf spring elastic piece 210 and the adapter assembly 220, and the first connecting member 230 is installed through the through holes in the leaf spring elastic piece 210 and the adapter assembly 220 to fixably connect the second connecting end 212 of the leaf spring elastic piece 210 and the adapter assembly 220.

[0037] By connecting the second connecting end 212 of the leaf spring elastic piece 210 to the adapter assembly 220 using the first connecting member 230, the leaf spring elastic piece 210 and the adapter assembly 220 are connected more stably than by welding, and the metallic properties of the leaf spring elastic piece 210 are not affected, thus avoiding any influence on the vibration frequency of the leaf spring elastic piece 210. The adapter assembly 220 can be fixedly connected to the bracket 100 using methods such as welding or fitting and welding. By installing the adapter assembly 220, the leaf spring elastic piece 210 and the adapter assembly 220 are fixed by the first connecting member 230, and the leaf spring elastic piece 210 is fixedly connected to the bracket 100 via the adapter assembly 220. Compared to the case where the leaf spring elastic piece 210 is directly and fixedly connected to the bracket 100, the leaf spring elastic piece 210 does not need to be welded in direct contact with the bracket 100. Therefore, the influence of welding on the metallic properties of the leaf spring elastic piece 210 can be effectively avoided, and furthermore, the frequency matching between the leaf spring elastic piece 210 and the change in current direction can be improved, reducing errors due to vibration.

[0038] In this application, the elastic support module 200 includes a leaf spring elastic piece 210, an adapter assembly 220, and a first connecting member 230. The first connecting end 211 of the leaf spring elastic piece 210 is fixedly connected to the movable assembly 400, and the second connecting end 212 of the leaf spring elastic piece 210 is fixedly connected to the adapter assembly 220 via the first connecting member 230. This ensures that the entire leaf spring elastic piece 210 is fixedly connected to the bracket 100 via the adapter assembly 220. Compared to a method of fixing the leaf spring elastic piece 210 to the bracket 100 by direct welding, this method effectively avoids the influence of welding on the metallic properties of the leaf spring elastic piece 210. This avoids the influence on the vibration frequency of the leaf spring elastic piece 210, and further improves the agreement between the natural frequency of the leaf spring elastic piece 210 and the frequency of the current direction change. This ensures the accuracy and efficiency of the reciprocating motion of the reciprocating magnetic levitation linear motor 10 and improves product quality.

[0039] In one embodiment, referring again to Figures 1 to 4, the bracket 100 includes a housing 110 and a base 120, the base 120, the movable assembly 400 and the drive assembly 300 are provided within the housing 110, and both the drive assembly 300 and the adapter assembly 220 are fixedly attached to the base 120.

[0040] In this embodiment, the shape of the housing 110 can be various, such as a frame-shaped structure or a square ring-shaped structure, but it is not specifically limited here as it can be selected and designed according to actual needs. The base 120 is usually provided as a block-shaped or dish-shaped structure, and the base 120 and the housing 110 may be directly and fixedly connected, or they may be elastically connected via an elastic member. That is, by suspending and connecting the base 120 to the housing 110, further cushioning and vibration damping can be achieved. The housing 110 provides a certain degree of protection to structures such as the movable assembly 400 and the drive assembly 300, and is configured so that the entire linear motor is mounted inside the housing 110 of the electric shear device.

[0041] The bobbin of the drive assembly 300 can be fixedly attached to the base 120 by insertion and welding. Specifically, a positioning fitting groove 122 is provided in the base 120, and during installation, the adapter assembly 220 is first fitted into the positioning fitting groove 122 on the base 120, and then the joint between the adapter assembly 220 and the inner wall surface of the positioning fitting groove 122 can be welded. In this way, since it is not necessary to directly weld the leaf spring elastic piece 210 to the base 120, the effect of welding on the metallic properties of the leaf spring elastic piece 210 can be effectively reduced or avoided. By fixing both the drive assembly 300 and the adapter assembly 220 to the base 120, the weight of the drive assembly 300 is much greater than the weight of the movable assembly 400 compared to the method of fixing the adapter assembly 220 to the housing 110, so the drive assembly 300 can be fully utilized for cushioning and vibration damping to reduce vibration of the housing 110 and improve the comfort of using the product.

[0042] In one embodiment, as shown in Figures 1 to 5, the base 120 is elongated and extends in a predetermined direction. Both ends of the base 120 in the longitudinal direction protrude from the movable assembly 400 to form mounting segments 121. Positioning fitting grooves 122 are provided in the mounting segments 121, and the adapter assembly 220 is configured to be fitted into the positioning fitting grooves 122 and is welded to the inner surface of the positioning fitting grooves 122.

[0043] In this embodiment, when the base 120 extends in a predetermined direction and is elongated, the drive assembly 300 is generally fixedly connected to the central part of the base 120. Therefore, by allowing both ends of the base 120 in the longitudinal direction to protrude beyond the movable assembly 400 and fitting the adapter assembly 220 into the positioning fitting groove 122 of the mounting segment 121, interference of the drive assembly 300 with the vibration of the leaf spring elastic piece 210 can be effectively avoided, making the overall structure more compact and reducing the volume. By opening the positioning fitting groove 122 in the mounting segment 121 and configuring the adapter assembly 220 to be fitted into the positioning fitting groove 122, it is possible to mount the adapter assembly 220 based on pre-positioning using the positioning fitting groove 122, improving the convenience of mounting the adapter assembly 220 and the accuracy of assembly. To guarantee the performance of the product, both the base 120 and the adapter assembly 220 are made of metal. The stability of the connection between the adapter assembly 220 and the base 120 is ensured by welding the adapter assembly 220 to the inner surface of the positioning fitting groove 122, and furthermore, the stable performance of the product is guaranteed. Specifically, all parts where the outer wall of the adapter assembly 220 and the inner wall surface of the positioning fitting groove 122 come into contact are welded. In this way, the stability of the connection between the adapter assembly 220 and the base 120 can be further improved.

[0044] Furthermore, referring to Figures 1 to 4, the adapter assembly 220 includes two opposing fitting blocks that clamp both sides of the plate surface of the second connecting end 212, and the first connecting member 230 connects the two fitting blocks 221 and the second connecting end 212 by passing through them.

[0045] In this embodiment, the fitting block 221 may be a strip-shaped block structure or a rectangular block structure, and can be selected and designed according to the size of the leaf spring elastic piece 210, so it is not specifically limited here. The shape and dimensions of the two opposing fitting blocks 221 may be the same, different, or slightly different. In order to ensure consistency in the clamping of the second connecting end 212 by the two fitting blocks 221, the shape and dimensions of the two fitting blocks 221 may be the same. By clamping both sides of the plate surface of the second connecting end 212 with the two fitting blocks 221, the contact area between the fitting block 221 and the second connecting end 212 is maximized, making the fixing between the fitting block 221 and the second connecting end 212 more stable. The first connecting member 230 connects the two fitting blocks 221 and the second connecting end 212 by penetrating them, thereby forming a block-like structure with the fitting blocks 221 and the second connecting end 212 as a single unit, making it easier to install the second connecting end 212 into the positioning fitting groove 122. At the same time, since both sides of the plate surface of the second connecting end 212 of the leaf spring elastic piece 210 are sandwiched between the two fitting blocks 221, deformation and warping of the second connecting end 212 of the leaf spring elastic piece 210 are effectively prevented, thereby ensuring consistency between the frequency of the leaf spring elastic piece 210 and the frequency of the current direction change, and reducing errors due to vibration.

[0046] In one embodiment, as shown in Figures 1 to 4, the first connecting member 230 is a rivet, the upper surface of the base 120 is recessed to form a positioning fitting groove 122, and the base 120 is provided with a retraction space 124 corresponding to the rivet.

[0047] In this embodiment, by using a rivet for the first connecting member 230, loosening or detachment of the first connecting member 230 due to long-term vibration can be effectively avoided compared to structures such as bolts, thereby making the connection between the leaf spring elastic piece 210 and the adapter assembly 220 more stable and reliable. By recessing the upper surface of the base 120 to form a positioning fitting groove 122, the leaf spring elastic piece 210 and the adapter assembly 220 can be fitted into the positioning fitting groove 122 from top to bottom, making it easier to install the adapter assembly 220 into the positioning fitting groove 122 and improving the overall assembly efficiency. By providing a retraction space 124 at a position corresponding to the rivet on the base 120, interference of the base 120 with the installation of the rivet can be avoided.

[0048] Based on the above embodiment, and further referring to Figures 2 to 5, a positioning through hole 123 is provided in the bottom wall surface of the positioning fitting groove 122, and the fitting block 221 includes a main body portion 222 and an insertion portion 223 connected to the lower surface of the main body portion 222, the insertion portion 223 is configured to be inserted into the positioning through hole 123, and the main body portion 222 is configured to be fitted into the positioning fitting groove 122 and to abut against the bottom wall surface of the positioning fitting groove 122.

[0049] In this embodiment, a positioning through hole 123 is made in the bottom wall surface of the positioning fitting groove 122, and the fitting block 221 is configured to include a main body portion 222 and an insertion portion 223, with the insertion portion 223 being inserted into the positioning through hole 123. The main body portion 222 is fitted into the positioning fitting groove 122 and is configured to abut against the bottom wall surface of the positioning fitting groove 122. This enables two-stage positioning of the fitting block 221 and the base 120, effectively increasing the positioning area and welding area between the fitting block 221 and the base 120, improving the mounting accuracy between the fitting block 221 and the base 120, and making the connection between the fitting block 221 and the base 120 more stable and reliable.

[0050] Furthermore, as shown in Figures 2 to 6, both ends of the main body portion 222 in the width direction of the base 120 extend from the insertion portion 223, the width direction of the base 120 intersects with the vertical direction and the length direction of the base 120, the second connecting end 212 includes a main body segment 213 and an insertion segment 214 connected to the lower surface of the main body segment 213, the insertion segment 214 is installed sandwiched between the insertion portions 223 of the two fitting blocks 221, the main body segment 213 is installed sandwiched between the main body portions 22 of the two fitting blocks 221, the insertion segment 214 is inserted into the positioning through hole 123, the lower surface of the main body segment 213 abuts against the bottom wall surface of the positioning fitting groove 122. The main body portion 222 and the inner surface of the positioning fitting groove 122, and the insertion portion 223 and the inner surface of the positioning through hole 123 are all provided to be welded together.

[0051] In this embodiment, the main body portion 222 is generally a strip-shaped block structure. The second connecting end portion 212 includes a main body segment 213 and an insertion segment 214, with the main body segment 213 being sandwiched between the main body portions 222 of the two fitting blocks 221, and the insertion segment 214 being sandwiched between the insertion portions 223 of the two fitting blocks 221. In other words, by providing the second connecting end portion 212 in accordance with the fitting blocks 221, the contact area between the second connecting end portion 212 and the fitting blocks 221 can be effectively increased, further improving the mounting accuracy between the second connecting end portion 212 and the fitting blocks 221. Specifically, the width direction of the base 120 intersects with the length direction and the vertical direction of the base 120. By installing the main body portion 222 with both ends in the width direction of the base 120 extending from the insertion portion 223, and by installing the main body segment 213 with both ends in the width direction of the base 120 extending from the insertion segment 214, the entire second connecting end 212 can be kept in a sheet-like shape, making the clamping of the second connecting end 212 by the two fitting blocks 221 more stable and reliable.

[0052] To avoid interference, the positioning fitting groove 122 may be provided so that both ends in the width direction of the base 120 penetrate the side wall of the base 120. In this way, the positioning fitting groove 122 becomes a through groove in the width direction of the base 120. This effectively avoids mounting interference caused by manufacturing tolerances or deformations of the fitting block 221 and the base 120. At the same time, it makes welding between the fitting block 221 and the base 120 easier.

[0053] The inner surfaces of the main body 222 and the positioning fitting groove 122, and the inner surfaces of the insertion portion 223 and the positioning through hole 123 are all provided to be welded. Specifically, the bottom wall surface of the main body 222 and the bottom wall surface of the fitting groove, the spaced side walls of the two main body portions 222 and the side walls of the fitting groove, and the bottom periphery of the insertion portion 223 and the inner periphery of the positioning through hole 123 are all welded. This maximizes the connection stability between the fitting block 221 and the base 120, reduces the impact of welding on the metallic properties of the leaf spring elastic piece 210, and further improves the motor frequency matching.

[0054] In one embodiment, referring to Figures 1 to 6, the leaf spring elastic piece 210 extends in a spiral shape, the central end of the leaf spring elastic piece 210 forms a first connecting end 211, and the outer end of the leaf spring elastic piece 210 forms a second connecting end 212. The movable assembly 400 includes a magnet mounting seat 410 and a magnet 420 attached to the magnet mounting seat 410. Connecting segments 411 are formed at both ends of the magnet mounting seat 410, and each connecting segment 411 is inserted and welded to correspond to one of the first connecting ends 211.

[0055] In this embodiment, when the leaf spring elastic piece 210 is wound from the center outward, it may be wound in the shape of a mosquito coil or a racetrack, and is not specifically limited here. The central end of the leaf spring elastic piece 210 is the starting point of the center of the spiral, and the outer end of the leaf spring elastic piece 210 is the outer end of the spiral. By winding the leaf spring elastic piece 210 from the center, the elastic arm of the leaf spring elastic piece 210 can be made longer in the same occupied space compared to other structures, so that sufficient elastic force and support force can be provided to the movable assembly 400. In other words, with the leaf spring elastic piece 210 of this embodiment, sufficient elastic force and support force can be guaranteed while reducing the occupied space, so the overall volume is reduced.

[0056] The magnet mounting base 410 is made of metal to ensure structural strength. Specifically, a through hole is made at the central end of the leaf spring elastic piece 210, and the connecting segment 411 is configured to be inserted into this through hole. By inserting the connecting segments 411 at both ends of the magnet mounting base 410 into the central end (first connecting end 211) of the leaf spring elastic piece 210, mounting based on pre-positioning of the magnet mounting base 410 and the central end of the leaf spring elastic piece 210 is achieved, making subsequent welding work easier. The central end of the leaf spring elastic piece 210 is fixedly connected to the magnet mounting base 410, that is, the magnet 420 drives the central end of the leaf spring elastic piece 210 to reciprocate in a predetermined direction, and transmits vibrations to the base 120 via the leaf spring elastic piece 210. Since the central end of the leaf spring elastic piece 210 is the starting point of vibration and the outer end is the ending point of vibration, the metallic properties of the outer end of the leaf spring elastic piece 210 have a greater influence on the vibration frequency, while the metallic properties of the central end of the leaf spring elastic piece 210 have a smaller influence on the vibration frequency. On the other hand, by welding the connecting segment 411 of the magnet mounting seat 410 to the first connecting end 211, a stable connection between the magnet mounting seat 410 and the leaf spring elastic piece 210 can be ensured without substantially affecting the vibration frequency of the leaf spring elastic piece 210, and the leaf spring elastic piece 210 can be effectively prevented from detaching from the magnet mounting seat 410 due to long-term vibration.

[0057] Based on the embodiment in which the adapter assembly 220 described above is fixedly attached to the base 120, as shown in Figures 1 to 4 and 7, the reciprocating magnetic levitation linear motor 10 further includes two sets of suspension vibration damping modules 500, each suspension vibration damping module 500 including an elastic recovery piece 510, a clamping block assembly 520, and a second connecting member 530, the second connecting member 530 fixedly passing through the lower end of the elastic recovery piece 510 and the clamping block assembly 520, the clamping block assembly 520 being fixedly connected to the base 120, and the upper end of the elastic recovery piece 510 being fixedly connected to the housing 110 such that the base 120 and the housing 110 are spaced apart.

[0058] In this embodiment, the elastic recovery piece 510 uses an elastic material while also possessing a certain degree of rigidity. For example, the elastic recovery piece 510 can specifically be a sheet metal part. Each set of suspension damping modules 500 may include several elastic recovery pieces 510. For example, each set of suspension damping modules 500 may include only one elastic recovery piece 510, or it may include two or more elastic recovery pieces 510 that are stacked or spaced apart. The number of elastic recovery pieces 510 can be selected and designed according to actual needs and is not specifically limited here. The shape of the elastic recovery piece 510 can be various, such as a mosquito coil shape, a racetrack spiral shape, or a frame shape. The elastic recovery piece 510 is configured to suspend the base 120 from the housing 110 and provide effective cushioning and vibration damping between the base 120 and the housing 110.

[0059] When the base 120 is suspended from the housing 110 via the suspension vibration damping module 500, vibrations from the movable assembly 400 are first transmitted to the base 120 via the elastic support module 200, where most of the vibrations are absorbed by the drive assembly 300 on the base 120. These vibrations are then transmitted to the elastic recovery piece 510 of the suspension vibration damping module 500 for further absorption, and finally transmitted to the housing 110. In this way, the vibrations of the entire linear motor are almost entirely absorbed by the drive assembly 300 and the suspension vibration damping module 500, effectively reducing the perceived vibration of the entire housing 110. When one end of the elastic recovery piece 510 is connected to the base 120 and the other end is connected to the housing 110, the combined weight of the base 120 and the fixed assembly is much greater than the combined weight of the movable assembly 400 and the cutter head assembly, compared to the configuration where one end of the elastic recovery piece 510 is connected to the movable assembly 400 and the other end is connected to the housing 110. Therefore, the initial acceleration applied to the elastic recovery piece 510 by the movable assembly 400 is smaller, and the amplitude of the vibration of the elastic recovery piece 510 relative to the housing 110 is smaller, which is advantageous for vibration damping. The operability of this electric shearing device using a linear motor is more comfortable, and this is especially noticeable with high-frequency vibrations.

[0060] To improve structural strength, the elastic recovery piece 510 and the clamping block assembly 520 are usually made of metal. The upper end of the elastic recovery piece 510 and the housing 110 can be fixedly connected by methods such as welding or riveting. The structure of the clamping block assembly 520 can be various. For example, the clamping block assembly 520 can be a block-shaped structure, a plate-shaped structure, etc. The second connecting member 530 can specifically be a rivet, screw, bolt, etc. Specifically, through holes are made in both the lower end of the elastic recovery piece and the clamping block assembly 520, and the second connecting member 530 is installed through the through holes in the elastic recovery piece 510 and the clamping block assembly 520 to fixably connect the lower end of the elastic recovery piece 510 and the clamping block assembly 520. By connecting the lower end of the elastic recovery piece 510 to the clamping block assembly 520 using the second connecting member 530, the elastic recovery piece 510 and the clamping block assembly 520 are connected more stably than by welding, and the metallic properties of the elastic recovery piece 510 are not affected, and furthermore, the vibration frequency of the elastic recovery piece 510 is avoided. The clamping block assembly 520 can be fixedly connected to the base 120 using methods such as welding or fitting and welding. By providing the clamping block assembly 520, the elastic recovery piece 510 and the clamping block assembly 520 are fixed via the second connecting member 530, and the elastic recovery piece 510 is fixedly connected to the base 120 via the clamping block assembly 520. Compared to the case where the elastic recovery piece 510 is directly fixedly connected to the base 120, there is no need to directly contact the elastic recovery piece 510 with the housing 110 and weld it, the effect of welding on the metallic properties of the elastic recovery piece 510 can be effectively avoided, and the vibration damping effect can be enhanced.

[0061] Furthermore, referring to Figures 1 to 4, the clamping block assembly 520 includes two opposing clamping blocks 521, the lower end of the elastic recovery piece 510 is positioned between the two clamping blocks 521, and the second connecting member 530 connects the two clamping blocks 521 and the elastic recovery piece 510 by passing through them.

[0062] In this embodiment, the clamping block 521 may be specifically a strip-shaped block structure or a rectangular block structure, and can be selected and designed according to the size of the elastic recovery piece 510, so it is not specifically limited here. The shape and dimensions of the two opposing clamping blocks 521 may be the same, different, or slightly different. In order to ensure consistency in clamping the lower end of the elastic recovery piece 510 by the two clamping blocks 521, the shape and dimensions of the two clamping blocks 521 may be the same. By clamping both sides of the plate surface at the lower end of the elastic recovery piece 510 with the two clamping blocks 521, the contact area between the clamping block 521 and the elastic recovery piece 510 is maximized, making the fixation between the clamping block 521 and the elastic recovery piece 510 more stable. The second connecting member 530 penetrates and connects the two clamping blocks 521 and the lower end of the elastic recovery piece 510, thereby forming a block-like structure with the clamping blocks 521 and the lower end of the elastic recovery piece 510 as a single unit, making it easier to attach the lower end of the elastic recovery piece 510 to the base 120. At the same time, since both sides of the plate surface of the lower end of the elastic recovery piece 510 are sandwiched between the two clamping blocks 521, deformation and warping of the lower end of the elastic recovery piece 510 are effectively prevented, further guaranteeing the vibration damping effect of the elastic recovery piece 510.

[0063] Furthermore, as shown in Figures 1 to 5, fitting protrusions 125 are provided on both ends of the base 120 in a predetermined direction, and the clamping block 521 and the elastic recovery piece 510 are provided with a first insertion hole 522 and a second insertion hole 512, respectively, corresponding to the fitting protrusions 125, and the fitting protrusions 125 are configured to be inserted into the first insertion hole 522 and the second insertion hole 512, and the fitting protrusions 125 are welded to the inner wall surface of the first insertion hole 522.

[0064] In this embodiment, during installation, the fitting protrusions 125 at both ends of the base 120 are fitted into the first insertion hole 522 of the clamping block 521 and the second insertion hole 512 of the elastic recovery piece 510, respectively. This enables installation based on pre-positioning of the base 120, clamping block 521, and elastic recovery piece 510, making subsequent welding work easier. On the other hand, welding the fitting protrusions 125 of the base 120 to the inner wall surface of the first insertion hole 522 ensures a stable connection between the base 120 and clamping block 521 and the elastic recovery piece 510 without substantially affecting the vibration frequency of the elastic recovery piece 510, effectively preventing the elastic recovery piece 510 and clamping block 521 from detaching from the base 120 due to long-term vibration. Specifically, the outer circumferential surface of the fitting protrusions 125 is welded to the inner wall surface of the first insertion hole 522.

[0065] In one embodiment, referring also to Figure 7, the elastic recovery piece 510 includes a laterally extending segment 511 and two adjacent vertically extending segments 514, the lower ends of the two vertically extending segments 514 each connected to the ends of the laterally extending segment 511, a second insertion hole 512 is opened in the laterally extending segment 511, two clamping blocks 521 are provided to sandwich both sides of the laterally extending segment 511, a second connecting member 530 connects the two clamping blocks 521 and the laterally extending segment 511 through it, and the suspension vibration damping module 500 further includes a lateral connecting piece 540, the upper ends of the two vertically extending segments 514 are provided to be sandwiched between the lateral connecting piece 540 and the housing 110.

[0066] In this embodiment, the laterally extending segment 511 is integrally molded with two vertically extending segments 514. Since the elastic recovery piece 510 includes the laterally extending segment 511 and the two vertically extending segments 514 arranged side by side, the elastic recovery piece 510 is substantially U-shaped. By making the elastic recovery piece 510 U-shaped, compared to the case where the elastic recovery piece 510 is ring-shaped, the upper end opening of the elastic recovery piece 510 can absorb mounting errors, and furthermore, the assembly of the elastic recovery piece 510 with the clamping block assembly 520 and the housing 110 is made more stable, and deformation of the elastic recovery piece 510 that affects the elastic recovery effect can be effectively avoided. By providing the lateral connecting piece 540, the upper ends of the two vertically extending segments 514 are provided to be sandwiched between the lateral connecting piece 540 and the housing 110, so that a stable connection between the vertically extending segments 514 and the housing 110 can be guaranteed.

[0067] The U-shaped elastic recovery piece 510 has a simple structure and is easy to assemble. The two vertically extending segments 514 of the elastic recovery piece 510 provide a stable elastic recovery force, and furthermore, can guarantee the vibration damping and support effect of the entire suspension vibration damping module 500. Two clamping blocks 521 are provided to sandwich both sides of the laterally extending segment 511, and a second connecting member 530 connects the clamping blocks 521 and the laterally extending segment 511 by penetrating them. This fully utilizes the laterally extending segment 511 to achieve a fixed connection between the elastic recovery piece 510 and the clamping blocks 521, while avoiding the second connecting member 530 and the fitted protruding block 125 affecting the elastic recovery effect of the two vertically extending segments 514.

[0068] In one embodiment, as shown in Figures 1 to 3 and 7, the second connecting member 530 is a rivet, and two through holes 513 are provided in the lateral extending segment 511 at positions corresponding to the two vertical extending segments 514, and the second insertion hole 512 is located between the two through holes 513, and the rivet passes through the through holes 513 and the clamping block 521 to permanently connect the elastic recovery piece 510 and the clamping block 521 module, and the upper end of each vertical extending segment 514 is permanently connected between the housing 110 and the lateral connecting piece 540 by a single rivet.

[0069] In this embodiment, by using a rivet for the second connecting member 530, loosening or detachment of the second connecting member 530 due to long-term vibration can be effectively avoided compared to structures such as bolts, and furthermore, the connection between the elastic recovery piece 510 and the clamping block assembly 520 can be made more stable and reliable. The second insertion hole 512 is located between the two through holes 513, and by fixing both lateral ends of the two clamping blocks 521 to the laterally extending segment 511 using one rivet each, warping or deformation of both lateral ends of the laterally extending segment 511 can be avoided, and the connection between the laterally extending segment 511 and the clamping block 521 can be made smoother and more reliable. In addition, when the elastic recovery piece 510 and the two clamping blocks 521 are connected using a rivet, the elastic recovery piece 510 and the clamping blocks 521 form a single module as an integral part. Then, the fitting block 221 on the base 120 is fitted to the clamping block 521 and the central part of the lateral extension segment 511, and the edges that come into contact with each other are welded to fix the suspension vibration damping module 500 to the base 120. This fixing method is simple, quick, and easy to install. The upper end of each vertical extension segment 514 is fixedly connected to the housing 110 and the lateral connecting piece 540 using a single rivet, thereby ensuring the stability of the connection between the vertical extension segment 514 and the housing 110 and the lateral connecting piece 540, and preventing loosening or detachment due to long-term use.

[0070] In one embodiment, referring to Figures 1 and 2, the housing 110 includes a housing body 111 and mounting protrusions 112 connected to the top surfaces of both ends of the housing body 111 in a predetermined direction, and the upper end of the elastic recovery piece 510 is fixedly connected to the inner surface of the mounting protrusions 112 such that the top surface of the elastic recovery piece 510 is higher than or flush with the top surface of the leaf spring elastic piece 210.

[0071] By providing a mounting protrusion 112 on the top surface of the housing body 111 and fixing the upper end of the elastic recovery piece 510 to the inner surface of the mounting protrusion 112, interference between the external structure of the housing body 111 and the elastic recovery piece 510's elastic restoration is avoided. Note that the longer the elastic recovery piece 510, the smaller its amplitude of oscillation. If the effective pendulum length of the elastic recovery piece 510 is shorter than the effective pendulum length of the leaf spring elastic piece 210, the vibration transmitted from the base 120 to the elastic recovery piece 510 causes a large amplitude of oscillation in the elastic recovery piece 510, resulting in a strong vibration sensation in the housing 110. On the other hand, by making the top surface of the elastic recovery piece 510 higher than or flush with the top surface of the leaf spring elastic piece 210, the effective pendulum length of the elastic recovery piece 510 can be made greater than or equal to the effective pendulum length of the leaf spring elastic piece 210, and the amplitude of oscillation of the elastic recovery piece 510 can be relatively reduced, thereby further weakening the vibration sensation of the housing 110.

[0072] This invention further proposes an electric shearing device comprising a cutter head assembly and a reciprocating magnetic levitation linear motor 10. The specific structure of the reciprocating magnetic levitation linear motor 10 is described in the above embodiment, and the movable assembly 400 of the reciprocating magnetic levitation linear motor 10 is connected to the cutter head assembly so as to cause the cutter head assembly to reciprocate. This electric shearing device adopts all the technical ideas of all the above embodiments and therefore has at least all the beneficial effects of the technical ideas of the above embodiments, which are omitted here.

[0073] This electric shearing device may specifically be a shaver, hair cutter, hair trimmer, etc., and is not specifically limited here. If the reciprocating magnetic levitation linear motor 10 has only one movable assembly 400, one movable cutter head and a fixed cutter head are provided, and this movable cutter head is connected to the movable assembly 400 of the reciprocating magnetic levitation linear motor 10, and the reciprocating magnetic levitation linear motor 10 moves the movable cutter head back and forth relative to the fixed cutter head to achieve shearing. If the reciprocating magnetic levitation linear motor 10 has two movable assemblies 400, the cutter head is made to include two movable cutter heads, and the two movable cutter heads are each connected to two movable assemblies 400, and the reciprocating magnetic levitation linear motor 10 moves the two movable cutter heads back and forth in opposite directions to achieve shearing.
