Description

[Technical field]

[0001] The present application relates to the technical field of linear motors, and more particularly to reciprocating magnetically levitated linear motors. [Background technology]

[0002] A reciprocating magnetic levitation linear motor, also known as a linear motor, is mainly composed of a movable assembly (mover) including a permanent magnet, and a drive 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 a reciprocating linear motor moves back and forth with respect to the iron core coil at a certain frequency. In this case, support by an elastic support mechanism is required to secure the gap between the permanent magnet and the iron core. This elastic support mechanism can also provide an elastic restoring force for the reciprocating motion of the permanent magnet.

[0003] In the linear motor of the related art, the elastic support mechanism is provided as an elastic piece, one end of which is fixed to the permanent magnet and the other end of which is directly welded to the base or housing of the bracket. However, if the elastic piece is directly welded to the base or housing, the metal properties will be affected, which will affect the vibration frequency of the elastic piece, and the consistency between the natural frequency of the elastic piece and the permanent magnet and the frequency of the current direction change will be low, which will affect the accuracy and efficiency of the reciprocating motion of the motor.

[0030] This application proposes a reciprocating magnetically levitated linear motor.

[0031] In the embodiment of the present application, referring to FIG. 1 to FIG. 4, the reciprocating magnetic levitation linear motor 10 includes a bracket 100, two sets of elastic support modules 200, a driving assembly 300, and a movable assembly 400 that floats above the driving assembly 300. The driving assembly 300 is attached to the bracket 100 so as to reciprocate the movable assembly 400 in a predetermined direction by electromagnetic action. Both ends of the movable assembly 100 in the predetermined direction are respectively connected to the bracket 100 via a set of elastic support modules 200. The elastic support module 200 is connected to the racket 100, and includes a leaf spring elastic piece 210, an adapter assembly 220, and a first connecting member 230, where the leaf spring elastic piece 210 includes a first connecting end 211 and a second connecting end 212, the first connecting end 211 is fixedly connected to the movable assembly 400, the first connecting member 230 penetrates and fixes the second connecting end 212 to the adapter assembly 220, and the leaf spring elastic piece is fixedly connected 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 attachment 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. 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. The bracket 100 may also include 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 the base 120 or the housing 110.

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

[0034] In the embodiment of the present application, when directional instructions (e.g., up, down, left, right, front, back, etc.) are used, the directional instructions are only used to describe the relative positional relationship, movement status, etc. between each part in a certain posture, and if the specific posture changes, the directional instructions 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, and the movable assembly 400 is levitated above the driving assembly 300 by the elastic support modules 200. When a current whose direction alternates between positive and negative is passed through the coil of the driving assembly 300, the driving assembly 300 becomes an electromagnet, and the magnetic induction between the electromagnet and the permanent magnet and the elastic restoring action by the two elastic support modules 200 drive the driving assembly 300 to reciprocate in a predetermined direction. In actual use, by attaching a cutter head assembly to the magnet mounting seat 410 of the movable assembly 400, the reciprocating magnetic levitation linear motor 10 can cut hair by quickly reciprocating the movable blade of the electric shearing device relative to the fixed blade, or by reciprocating the two movable blades of the electric shearing device in opposite directions.

[0035] The leaf spring elastic piece 210 is specifically a plate-like structure having a certain elasticity, and generally uses a sheet metal part 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 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 actual needs, and is not specifically limited here. The shape of the leaf spring elastic piece 210 can be various shapes, 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 can reciprocate in a predetermined direction while the leaf spring elastic piece 210 can provide an elastic restoring force in the opposite direction.

[0036] In order to improve the structural strength, the adapter assembly 220 and the bracket 100 are usually made of metal materials. The first connection end 211 of the leaf spring elastic piece 210 and the movable assembly 400 can also be fixedly connected by welding, fitting, and other methods. The adapter assembly 220 can have various structures. For example, the adapter assembly 220 can be a block structure, a plate structure, and the like. The first connection member 230 can be specifically a structure such as a rivet, a screw, or a bolt. Specifically, a through hole is opened in both the second connection end 212 of the leaf spring elastic piece 210 and the adapter assembly 220, and the first connection member 230 is installed through the through hole between the leaf spring elastic piece 210 and the adapter assembly 220, thereby fixedly connecting the second connection end 212 of the leaf spring elastic piece 210 and the adapter assembly 220.

[0037] By using the first connecting member 230 to connect the second connecting end 212 of the leaf spring elastic piece 210 to the adapter assembly 220, the leaf spring elastic piece 210 and the adapter assembly 220 can be connected more stably than by a welding method, and the metal properties of the leaf spring elastic piece 210 are not affected, so that the vibration frequency of the leaf spring elastic piece 210 is not affected. The adapter assembly 220 can be fixedly connected to the bracket 100 by using a method 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 with the case where the leaf spring elastic piece 210 is directly and fixedly connected to the bracket 100, there is no need for the leaf spring elastic piece 210 to be welded in direct contact with the bracket 100, so that the influence on the metal properties of the leaf spring elastic piece 210 due to welding can be effectively avoided, and further, the frequency consistency of the leaf spring elastic piece 210 and the change in the current direction can be improved, and errors caused by vibration can be reduced.

[0038] In the present application, the elastic support module 200 includes a leaf spring elastic piece 210, an adapter assembly 220, and a first connecting member 230, and 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, so that the entire leaf spring elastic piece 210 is fixedly connected to the bracket 100 via the adapter assembly 220. Compared with the method of directly fixing the leaf spring elastic piece 210 to the bracket 100 by welding, the influence on the metal properties of the leaf spring elastic piece 210 caused by welding can be effectively avoided, so that the influence on the vibration frequency of the leaf spring elastic piece 210 can be avoided, and the agreement between the natural frequency of the leaf spring elastic piece 210 and the frequency of the current direction change can be improved, so that the accuracy and efficiency of the reciprocating motion of the reciprocating magnetic levitation linear motor 10 can be ensured, and the product quality can be improved.

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

[0040] In this embodiment, the shape of the housing 110 may be various shapes, such as a frame structure, a square ring shape, etc., but is not specifically limited here because 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 to each other, or may be elastically connected to each other via an elastic member. That is, the base 120 can be suspended and connected to the housing 110 to further cushion and damp vibration. The housing 110 provides a certain degree of protection for the structures such as the movable assembly 400 and the driving assembly 300, and is configured so that the entire linear motor is mounted within the housing 110 of the electric shearing device.

[0041] The bobbin of the drive assembly 300 can be fixedly attached to the base 120 by a method of insertion and welding. Specifically, the base 120 is provided with a positioning fitting groove 122, 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 influence of welding on the metal 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, compared with the method of fixing the adapter assembly 220 to the housing 110, the weight of the drive assembly 300 is much larger than the weight of the movable assembly 400, so that the drive assembly 300 can be fully utilized for buffering and vibration control to reduce the 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 extends in a predetermined direction and is elongated, and both ends of the base 120 in the longitudinal direction protrude from the movable assembly 400 to form an attachment segment 121, a positioning mating groove 122 is formed in the attachment segment 121, and the adapter assembly 220 is configured to be fitted into the positioning mating groove 122 and is welded to the inner surface of the positioning mating groove 122.

[0043] In this embodiment, when the base 120 is elongated in a predetermined direction, the driving assembly 300 is generally fixedly connected to the center of the base 120. Therefore, by making both ends of the base 120 in the length direction protrude beyond the movable assembly 400 and fitting the adapter assembly 220 into the positioning fitting groove 122 of the mounting segment 121, it is possible to effectively avoid interference of the driving assembly 300 with the deflection of the leaf spring elastic piece 210, and to make the entire structure more compact and reduce the volume. By forming 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 install the adapter assembly 220 based on the positioning of the positioning fitting groove 122, and the convenience of installing the adapter assembly 220 and the accuracy of assembly can be improved. In order to ensure the usability of the product, both the base 120 and the adapter assembly 220 are made of metal materials. Welding the adapter assembly 220 to the inner surface of the positioning fitting groove 122 ensures the stability of the connection between the adapter assembly 220 and the base 120, and also ensures stable performance of the product. Specifically, all of the contact areas between the outer peripheral wall of the adapter assembly 220 and the inner wall surface of the positioning fitting groove 122 are welded. In this way, the stability of the connection between the adapter assembly 220 and the base 120 can be further improved.

[0044] Further, referring to Figures 1 to 4, the adapter assembly 220 includes two opposing fitting blocks which clamp both sides of the plate surface of the second connection end 212, and the first connection member 230 penetrates and connects the two fitting blocks 221 and the second connection end 212.

[0045] In this embodiment, the fitting block 221 may be specifically a strip-shaped block structure or a square block structure, and may be selected and designed according to the size of the leaf spring elastic piece 210, so it is not specifically limited here. The shapes and dimensions of the two opposing fitting blocks 221 may be the same, different, or slightly different. In order to ensure the consistency of the clamping of the second connecting end 212 by the two fitting blocks 221, the shapes 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, and the fixing between the fitting block 221 and the second connecting end 212 is more stable. The first connecting member 230 penetrates and connects the two fitting blocks 221 and the second connecting end 212, so that the fitting block 221 and the second connecting end 212 form a block-like structure as a whole, which makes it easier to install the second connecting end 212 in 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 can be effectively prevented, which in turn ensures the consistency between the leaf spring elastic piece 210 and the frequency of the current direction change, and reduces errors caused by vibration.

[0046] In one embodiment, as shown in FIGS. 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 retreat space 124 corresponding to the rivet.

[0047] In this embodiment, by using a rivet as the first connecting member 230, loosening or coming off of the first connecting member 230 due to long-term vibration can be effectively prevented compared to a structure such as a bolt, and the connection between the leaf spring elastic piece 210 and the adapter assembly 220 can be made more stable and reliable. By forming the positioning fitting groove 122 by recessing the upper surface of the base 120, 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 attach 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 with the attachment of the rivet by the base 120 can be avoided.

[0048] Based on the above embodiment, and further referring to Figures 2 to 5, a positioning through hole 123 is opened 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 underside 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 inserted into the positioning fitting groove 122 and abut against the bottom wall surface of the positioning fitting groove 122.

[0049] In this embodiment, a positioning through hole 123 is opened in the bottom wall surface of the positioning fitting groove 122, the fitting block 221 includes a main body portion 222 and an insertion portion 223, and the insertion portion 223 is configured to be inserted into the positioning through hole 123. The main body portion 222 is configured to be fitted into the positioning fitting groove 122 and 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, and further improving the mounting accuracy between the fitting block 221 and the base 120, as well as making the connection between the fitting block 221 and the base 120 more stable and reliable.

[0050] 2 to 6, both ends of the main body 222 in the width direction of the base 120 are extended 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 connection 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 sandwiched and installed between the insertion portions 223 of the two fitting blocks 221, the main body segment 213 is sandwiched and installed between the main body portions 22 of the two fitting blocks 221, the insertion segment 214 is inserted into the positioning through hole 123, and the lower surface of the main body segment 213 abuts against the bottom wall surface of the positioning fitting groove 122; The main body 222, 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 222 is generally a strip-shaped block structure. The second connection end 212 includes a main body segment 213 and an insertion segment 214, the main body segment 213 is sandwiched between the main body parts 222 of the two fitting blocks 221, and the insertion segment 214 is sandwiched between the fitting parts 223 of the two fitting blocks 221, that is, the second connection end 212 is provided following the fitting block 221, so that the contact area between the second connection end 212 and the fitting block 221 can be effectively increased, and the installation accuracy between the second connection end 212 and the fitting block 221 can be further improved. Specifically, the width direction of the base 120 intersects with the length direction and the up-down direction of the base 120. When both ends of the main body portion 222 in the width direction of the base 120 are extended from the insertion portion 223, and both ends of the main body segment 213 in the width direction of the base 120 are also extended from the insertion segment 214, the entire second connection end 212 can be kept in a sheet-like form, and the clamping of the second connection end 212 by the two insertion blocks 221 can be made more stable and reliable.

[0052] In order to avoid interference, both ends of the positioning fitting groove 122 in the width direction of the base 120 may be provided to penetrate the side walls of the base 120. In this way, the positioning fitting groove 122 is a through groove in the width direction of the base 120. This makes it possible to effectively avoid the occurrence of attachment interference due to manufacturing tolerances and deformations of the fitting block 221 and the base 120. At the same time, welding between the fitting block 221 and the base 120 is made easier.

[0053] The main body 222 and the inner surface of the positioning fitting groove 122, and the insert portion 223 and the inner surface of 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 mutually separated side walls of the two main bodies 222 and the side wall surfaces of the fitting groove, and the bottom peripheral edge of the insertion portion 223 and the inner peripheral edge of the positioning through hole 123 are all welded. This maximizes the connection stability between the fitting block 221 and the base 120, while reducing the effect of welding on the metal properties of the leaf spring elastic piece 210, and further improves the consistency of the motor frequency.

[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, and the movable assembly 400 includes a magnet mounting seat 410 and a magnet 420 mounted on the magnet mounting seat 410, and connecting segments 411 are formed on both ends of the magnet mounting seat 410, and each connecting segment 411 is inserted and welded to one of the first connecting ends 211.

[0055] In this embodiment, when the leaf spring elastic piece 210 is wound from the center to the outside, the leaf spring elastic piece 210 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 end 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 making the leaf spring elastic piece 210 into a shape wound 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 supporting force can be provided to the movable assembly 400. In other words, the leaf spring elastic piece 210 of this embodiment can reduce the occupied space while ensuring sufficient elastic force and supporting force, so that the overall volume is smaller.

[0056] The magnet mounting seat 410 is made of a metal material to ensure structural strength. Specifically, a through hole is formed at the central end of the leaf spring elastic piece 210, and the connection segment 411 is inserted into the through hole. By inserting the connection segments 411 at both ends of the magnet mounting seat 410 into the central end (first connection end 211) of the leaf spring elastic piece 210, mounting based on the pre-positioning of the magnet mounting seat 410 and the central end of the leaf spring elastic piece 210 is realized, making the subsequent welding work easier. In addition, the central end of the leaf spring elastic piece 210 is fixedly connected to the magnet mounting seat 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 vibration 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 metal properties of the outer end of the leaf spring elastic piece 210 have a greater effect on the vibration frequency than the metal properties of the central end of the leaf spring elastic piece 210. Meanwhile, by welding the connection segment 411 of the magnet mounting seat 410 to the first connection end 211, a stable connection between the magnet mounting seat 410 and the leaf spring elastic piece 210 is guaranteed without substantially affecting the vibration frequency of the leaf spring elastic piece 210, and it is possible to effectively prevent the leaf spring elastic piece 210 from falling off the magnet mounting seat 410 due to long-term vibration.

[0057] Based on the above-mentioned embodiment in which the adapter assembly 220 is fixedly attached to the base 120, further, 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, the suspension vibration damping module 500 includes an elastic recovery piece 510, a clamping block assembly 520, and a second connecting member 530, the second connecting member 530 penetrates and fixes the lower end of the elastic recovery piece 510 and the clamping block assembly 520, the clamping block assembly 520 is fixedly connected to the base 120, and the upper end of the elastic recovery piece 510 is fixedly connected to the housing 110, so that the base 120 and the housing 110 are arranged with a gap between them.

[0058] In this embodiment, the elastic recovery piece 510 uses an elastic material and has a certain rigidity. For example, the elastic recovery piece 510 can be specifically a sheet metal part, etc. Each set of suspension vibration damping module 500 can include several elastic recovery pieces 510, for example, each set of suspension vibration damping module 500 may include only one elastic recovery piece 510, or may include two or more elastic recovery pieces 510 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 shapes, such as mosquito coil shape, racetrack spiral shape, frame shape, etc. The elastic recovery piece 510 is configured to suspend the base 120 on the housing 110 and provide effective buffering and vibration damping between the base 120 and the housing 110.

[0059] When the base 120 is suspended on the housing 110 via the suspension vibration damping module 500, the vibration of the movable assembly 400 is first transmitted to the base 120 via the elastic support module 200, and most of the vibration is absorbed by the drive assembly 300 on the base 120. The vibration is then transmitted to the elastic recovery piece 510 of the suspension vibration damping module 500 and further absorbed, and finally transmitted to the housing 110. In this way, the vibration of the entire linear motor is almost entirely absorbed by the drive assembly 300 and the suspension vibration damping module 500, so that the vibration sensation of the entire housing 110 can be effectively reduced. 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 with the case 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, so that the initial acceleration given 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 favorable for vibration suppression. The operability of this electric shearing device using a linear motor is more comfortable, and is particularly noticeable in high-frequency vibration.

[0060] In order to improve the structural strength, the elastic recovery piece 510 and the clamping block assembly 520 are usually made of metal materials. The upper end of the elastic recovery piece 510 and the housing 110 can be fixedly connected by welding, riveting, or other methods. The clamping block assembly 520 can have various structures. For example, the clamping block assembly 520 can be a block structure, a plate structure, or other structure. The second connecting member 530 can be specifically a structure such as a rivet, a screw, or a bolt. Specifically, a through hole is drilled 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 hole between the elastic recovery piece 510 and the clamping block assembly 520, thereby fixedly connecting 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 and 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 a welding method, and the metal properties of the elastic recovery piece 510 are not affected, and furthermore, the influence on 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 a method 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. Therefore, compared to the case where the elastic recovery piece 510 is directly and fixedly connected to the base 120, it is not necessary to directly contact and weld the elastic recovery piece 510 to the housing 110, and the influence on the metal properties of the elastic recovery piece 510 due to welding can be effectively avoided, and the vibration damping effect can be improved.

[0061] Furthermore, referring to Figures 1 to 4, the clamping block assembly 520 includes two clamping blocks 521 installed opposite each other, and the lower end of the elastic recovery piece 510 is installed so as to be sandwiched between the two clamping blocks 521, and the second connecting member 530 penetrates and connects the two clamping blocks 521 and the elastic recovery piece 510.

[0062] In this embodiment, the clamping block 521 may be specifically a strip-shaped block structure or a square block structure, and may be selected and designed according to the size of the elastic recovery piece 510, so it is not specifically limited here. The shapes and dimensions of the two opposing clamping blocks 521 may be the same, different, or slightly different. In order to ensure the consistency of the clamping of the lower end of the elastic recovery piece 510 by the two clamping blocks 521, the shapes and dimensions of the two clamping blocks 521 may be the same. By clamping both sides of the plate surface of 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, and the fixing between the clamping block 521 and the elastic recovery piece 510 is 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, so that the clamping blocks 521 and the lower end of the elastic recovery piece 510 form a block-like structure as a whole, 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 clamped between the two clamping blocks 521, deformation and warping of the lower end of the elastic recovery piece 510 can be effectively prevented, and the vibration damping effect of the elastic recovery piece 510 can be further guaranteed.

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

[0064] In this embodiment, during installation, the fitting convex blocks 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, thereby realizing installation based on the pre-positioning of the base 120, the clamping block 521, and the elastic recovery piece 510, and making the subsequent welding work easier. Meanwhile, by welding the fitting convex block 125 of the base 120 to the inner wall surface of the first insertion hole 522, a stable connection between the base 120, the clamping block 521, and the elastic recovery piece 510 is guaranteed without substantially affecting the vibration frequency of the elastic recovery piece 510, and the elastic recovery piece 510 and the clamping block 521 can be effectively prevented from falling off from the base 120 due to long-term vibration. Specifically, the outer circumferential surface of the fitting convex block 125 and the inner wall surface of the first insertion hole 522 are welded.

[0065] In one embodiment, referring also to FIG. 7 , the elastic recovery piece 510 includes a laterally extending segment 511 and two vertically extending segments 514 arranged side by side, the lower ends of the two vertically extending segments 514 are respectively connected to both 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 arranged to sandwich both sides of the laterally extending segment 511, a second connecting member 530 penetrates and connects the two clamping blocks 521 and the laterally extending segment 511, and the suspension vibration damping module 500 further includes a laterally connecting piece 540, and the upper ends of the two vertically extending segments 514 are arranged to be sandwiched between the laterally connecting piece 540 and the housing 110.

[0066] In this embodiment, the lateral extension segment 511 is integrally formed with the two vertical extension segments 514. The elastic recovery piece 510 includes the lateral extension segment 511 and the two vertical extension segments 514 arranged side by side, so that the elastic recovery piece 510 is substantially U-shaped. By making the elastic recovery piece 510 U-shaped, the upper end opening of the elastic recovery piece 510 can absorb installation errors compared to when the elastic recovery piece 510 is ring-shaped, and further, the assembly of the elastic recovery piece 510 with the clamping block assembly 520 and the housing 110 can be made more stable, and the elastic recovery piece 510 can be effectively prevented from being deformed and affecting the elastic recovery effect. By providing the lateral connection piece 540, the upper ends of the two vertical extension segments 514 are sandwiched between the lateral connection piece 540 and the housing 110, so that a stable connection between the vertical extension segment 514 and the housing 110 can be ensured.

[0067] The U-shaped elastic recovery piece 510 has a simple structure and is easy to assemble, and the two vertically extending segments 514 of the elastic recovery piece 510 can provide a stable elastic recovery force, and can ensure the vibration damping and supporting effect of the entire suspension vibration damping module 500. Two clamping blocks 521 are provided to sandwich both sides of the horizontally extending segment 511, and the second connecting member 530 penetrates and connects the clamping blocks 521 and the horizontally extending segment 511, thereby making full use of the horizontally extending segment 511 to realize a fixed connection between the elastic recovery piece 510 and the clamping blocks 521, and avoiding the second connecting member 530 and the fitting protruding block 125 from 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 drilled in the laterally extending segment 511 at positions corresponding to the two vertically extending segments 514, and the second insertion hole 512 is located between the two through holes 513, and the rivet passes through the through hole 513 and the clamping block 521 to fixedly connect the elastic recovery piece 510 and the clamping block 521 module, and the upper end of each vertically extending segment 514 is fixedly connected between the housing 110 and the laterally connecting piece 540 by one rivet.

[0069] In this embodiment, the second connecting member 530 is a rivet, which effectively prevents the second connecting member 530 from loosening or coming off due to long-term vibration, compared to a structure such as a bolt, 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 both ends of the two clamping blocks 521 in the lateral direction are fixedly connected to the laterally extending segment 511 using one rivet, thereby preventing warping or deformation of both ends of the laterally extending segment 511 in the lateral direction, and making the connection between the laterally extending segment 511 and the clamping block 521 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 block 521 form one module as a whole. Then, the mounting block 221 on the base 120 is mounted corresponding to the center of the clamping block 521 and the laterally extending segment 511, and the contacting edges of the two are welded to realize the fixing of the suspension vibration control module 500 to the base 120, which is simple, quick and easy to install. The upper end of each vertically extending segment 514 is fixedly connected to the housing 110 and the laterally connecting piece 540 with a rivet, which ensures the stability of the connection between the vertically extending segment 514 and the housing 110 and the laterally connecting piece 540 and prevents loosening or coming off due to long-term use.

[0070] In one embodiment, referring to Figures 1 and 2, the housing 110 includes a housing body 111 and a mounting convex block 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 convex block 112 so 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] The mounting protruding block 112 is provided on the top surface of the housing body 111, and the upper end of the elastic recovery piece 510 is fixedly connected to the inner surface of the mounting protruding block 112, thereby preventing the external structure of the housing body 111 from interfering with the elastic recovery of the elastic recovery piece 510. The longer the elastic recovery piece 510, the smaller its swing range. 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 swing range of the elastic recovery piece 510 is large due to the vibration transmitted from the base 120 to the elastic recovery piece 510, so that the vibration feeling of the housing 110 is strong. 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 equal to or greater than the effective pendulum length of the leaf spring elastic piece 210, and the swing range of the elastic recovery piece 510 can be relatively small, so that the vibration feeling of the housing 110 can be further weakened.

[0072] The present application further proposes an electric shearing device, which includes a cutter head assembly and a reciprocating magnetically levitated linear motor 10, the specific structure of the reciprocating magnetically levitated linear motor 10 can be referred to the above embodiment, and the movable assembly 400 of the reciprocating magnetically levitated linear motor 10 is connected to the cutter head assembly so as to reciprocate the cutter head assembly.

[0073] The electric shearing device may be a shaver, a hair cutter, a hair trimmer, etc., and is not specifically limited here. When the reciprocating magnetically levitated linear motor 10 has only one movable assembly 400, one movable cutter head and a fixed cutter head are provided, and the movable cutter head is connected to the movable assembly 400 of the reciprocating magnetically levitated linear motor 10, and the reciprocating magnetically levitated linear motor 10 reciprocates the movable cutter head relative to the fixed cutter head to achieve shearing.
