In this embodiment, the electric shearing device may specifically be an electric shaver, a hair clipper, a hair trimmer, or the like. The housing 100 is used to provide installation space and protection for the internal structure of the electric shears. The shape and size of the housing 100 may be selected and designed according to practical needs, and are not particularly limited herein. The material of the housing 100 may be metal, plastic, etc. Specifically, the electric shearing apparatus further includes a cutter head assembly 600 mounted to the housing 100, and the moving unit 240 is connected to the cutter head assembly 600 to drive the cutter head assembly 600 to reciprocate. The cutter head assembly 600 may take many forms, for example, the cutter head assembly 600 includes a movable cutter and a stationary cutter, and the moving unit 240 is connected to the movable cutter to drive the movable cutter to reciprocate relative to the stationary cutter to cut hair; the specific configuration of the cutter head assembly 600 is not limited herein.

The structure of the elastic supporting unit 250 may be many, for example, plastic parts, plate springs, etc., and the specific structure of the elastic supporting unit 250 is not limited herein, and only needs to provide a certain elastic force and supporting force. The driving unit 230 specifically includes a core, a bobbin, and a coil wound around the bobbin and mounted on the core through the bobbin. The iron core may be a U-shaped iron core, an E-shaped iron core, or the like, and different types of iron cores may be selected according to actual needs, which is not particularly limited herein.

After the coils of the driving unit 230 are energized with alternating current, the driving unit 230 forms an electromagnet, and the driving unit 230 drives the moving unit 240 to reciprocate along a preset direction by the magnetic induction of the electromagnet and the permanent magnet of the moving unit 240 and by the elastic recovery of the elastic supporting unit 250. In practical use, the linear motor 200 can drive the blade of the electric shearing apparatus to reciprocate rapidly by mounting the cutter head assembly 600 on the connecting seat of the moving unit 240.

The bracket 210 constitutes a frame of the entire linear motor 200, and provides mounting and support for the driving unit 230 and the like. The structure and form of the bracket 210 may be many, for example, the bracket 210 may be in a shell shape, a frame shape, or the like, which is not particularly limited herein. The mounting base 220 is used for providing mounting for the driving unit 230, and the driving unit 230 can be fixedly mounted on the mounting base 220 by welding, clamping and the like. The mounting block 220 may be provided in a block, a disc, a bar, a plate, etc.

The elastic suspension unit 300 may be made of a material having elasticity and a certain rigidity. For example, the elastic suspension unit 300 may be a plastic piece, a spring piece 310, or the like. The elastic suspension unit 300 may be fixedly connected to the bracket 210 by welding, heat fusing, screw connection, or the like. It will be appreciated that the mass of the drive unit 230 is much greater than the mass of the sub-assembly. Alternatively, the elastic suspension unit 300 includes two elastic sheets 310, and two ends of the mounting base 220 are respectively suspended and connected to the bracket 210 through one elastic sheet 310. Through making the fixed mounting of drive unit 230 in mount pad 220 for the both ends of mount pad 220 hang respectively through a shell fragment 310 and connect in support 210, compare in the scheme that the motion unit 240 is connected to elastic suspension unit 300 one end, the other end is connected to support 210, the weight of mount pad 220 plus drive unit 230 is greater than the weight of motion unit 240 plus tool bit subassembly 600 far away, then makes the initial acceleration of drive unit 230 for elastic suspension unit 300 less, thereby the swing of elastic suspension unit 300 is less relative to support 210, the shock attenuation effect is better.

The elastic shock absorbing unit 400 may be specifically a compression spring, various types of dampers, etc. The elastic shock absorbing unit 400 may be fixedly connected with the bracket 210, the housing 100, and the base by welding, sleeving, clamping, or the like. One end of the elastic shock absorbing unit 400 along the preset direction is connected to the mounting seat 220, and the other end is connected to the bracket 210 or the housing 100, indicating that the elastic shock absorbing unit 400 can absorb shock of the mounting seat 220 along the preset direction. The elastic damper unit 400 may be fixed between the mount 220 and the inner wall surface of the case 100, or may be mounted between the mount 220 and the bracket 210. It is understood that although the mount 220 is connected to the bracket 210 through the elastic suspension unit 300, it is capable of absorbing a shock of a portion of the moving unit 240. However, the elastic suspension unit 300 is inevitably swung in a predetermined direction, and there is a phenomenon in which the mount 220 hits the inner wall surface of the housing 100. By connecting one end of the elastic shock absorbing unit 400 in the preset direction to the mount 220 and the other end to the bracket 210 or the housing 100, the elastic shock absorbing unit 400 can further absorb the vibration of the mount 220 in the preset direction, and the end of the mount 220 in the preset direction is spaced from the inner wall surface of the housing 100. Thus, the mount 220 can be effectively prevented from striking the inner wall surface of the housing 100 due to vibration caused by the moving unit 240, thereby reducing noise of the product and improving quality of the product.

In order to reduce vibration, the elastic suspension unit 300 generally adopts a sheet structure. However, it is difficult for the elastic suspension unit 300 having a thin plate structure to secure parallelism of the reciprocating movement of the mount 220 in the preset direction within the bracket 210. By arranging the elastic shock absorbing unit 400 between the mounting base 220 and the bracket 210 or the housing 100, the elastic shock absorbing unit 400 can support and guide the mounting base 220, so that the transverse swing of the mounting base 220 in the vertical preset direction due to the transverse deviation of the elastic suspension unit 300 in the vertical preset direction is avoided, the parallelism of the whole motion unit 240 in the reciprocating motion in the preset direction is influenced, and the shearing precision of the whole electric shearing device is further ensured. It will be appreciated that the weight of the linear motor 200 is concentrated on the base. The elastic shock absorbing unit 400 may also support the base in the up-down direction so that the suspension pressure of the elastic suspension unit 300 may be reduced, and thus the service life of the elastic suspension unit 300 may be increased.

The electric shearing device of the utility model is characterized in that a moving unit 240 is connected with a mounting seat 220 through an elastic supporting unit 250 and is suspended above a driving unit 230; so that the driving unit 230 is mounted to the mounting base 220, and the mounting base 220 is suspended in the bracket 210 by the elastic suspension unit 300; an elastic shock absorbing unit 400 is provided between the mount 220 and the bracket 210 or the housing 100 such that an end of the mount 220 in a predetermined direction is spaced apart from an inner wall surface of the housing 100. Thus, the vibration of the moving unit 240 is primarily damped by the elastic suspension unit 300, and the mount 220 is secondarily damped by the elastic damping unit 400, so that the vibration of the entire linear motor 200 can be effectively reduced, and the vibration feeling of the entire electric shearing device can be further weakened. Meanwhile, the end part of the mounting seat 220 in the preset direction is always kept at a distance from the inner wall surface of the housing 100 through the elastic damping unit 400, so that the mounting seat 220 of the linear motor 200 can be effectively prevented from impacting the inner wall surface of the housing 100 due to vibration, and the noise and abnormal sound of the whole machine are reduced. And the elastic shock absorbing unit 400 can support and guide the reciprocating motion of the mounting seat 220 in the preset direction, so that the parallelism of the reciprocating motion of the whole motion unit 240 in the preset direction is ensured, and the use precision and reliability of the product are improved.

In addition, by enabling the two side ends of the mounting seat 220 along the preset direction to be respectively and elastically connected to the bracket 210 or the housing 100 through the at least one elastic shock absorbing unit 400, centering of the mounting seat 220 in the preset direction can be ensured, and further centering of the driving unit 230 and the moving unit 240 in the bracket 210 is ensured, so that moving dislocation is avoided. In other embodiments, only one elastic shock absorbing unit 400 may be provided, such that only one end of the base in a predetermined direction is elastically connected to the bracket 210 or the housing 100 through the elastic shock absorbing unit 400.

The clip 500 may be connected to the two mounting lugs 222, or may be fixedly connected to the bottom wall of the mounting body 221. It will be appreciated that the coils of the linear motor 200 are soldered to flexible wires inside the electric shears to achieve electrical conduction. Through setting up the solidus clamp 500, can advance location and spacing to the welding end of flexible wire for the welding end of flexible wire keeps the position at the adjacent coil leading-out end, and can avoid the flexible wire aversion when welding, then the welding operation of the welding end of flexible wire and the leading-out end of coil of operating personnel of being convenient for more. By fixing the wire fixing clip 500 between the two mounting lugs 222, the two mounting lugs 222 can pre-position the wire fixing clip 500, so that the positioning difficulty of the wire fixing clip 500 can be reduced, and the assembly efficiency of the wire fixing clip 500 on the mounting seat 220 can be improved.

Further, the mounting lug 222 is provided with a mounting post 223 protruding from a wall surface of the clip 500, and the elastic damping unit 400 includes a spring, one end of which is sleeved on the mounting post 223, and the other end of which is connected to the bracket 210.

By fixedly connecting the upper end of the spring 310 to the inner wall surface of the inner connecting section 215 above the outer connecting section 216, the effective swing length of the spring 310 is longer than that of the spring, and the swing amplitude of the spring 310 is smaller than that of the spring, so that the shock feeling of the housing 100 can be further weakened.

By locating the inner wall surface of the outer connecting section 216 outside the inner wall surface of the inner connecting section 215, the spring piece 310 can be prevented from striking the outer connecting section 216 to generate noise when vibrating in a predetermined direction. And through making the interval between spliced pole 218 and mounting column 223 be greater than the interval between shell fragment 310 and the interior wall surface of external connection section 216, namely, the effective compression distance of spring is greater than the interval between shell fragment 310 and the interior wall surface of external connection section 216, so, can effectively avoid the mount pad 220 striking the interior wall surface of external connection section 216 when vibrating in the direction of predetermineeing through the effect of spring, further weaken the shock sensation, reduce noise and abnormal sound.

In an embodiment, as shown in fig. 2, 3 and 5, the mounting main body 221 is elongated and extends along a predetermined direction, the driving unit 230 is fixed at a middle portion of the mounting main body 221 along the predetermined direction, the wire clip 500 is fixedly mounted on a bottom wall surface of the mounting main body 221 and is disposed corresponding to the driving unit 230, and the two mounting lugs 222 are distributed on two sides of a center of gravity of the driving unit 230.

In the present embodiment, the driving unit 230 is fixed to the middle part of the mounting body 221 in the length direction, so that the center of gravity of the entire linear motor 200 is located substantially above the center of the base. By arranging the wire fixing clamp 500 corresponding to the driving unit 230, the mounting lugs 222 are distributed on both sides of the center of gravity of the driving unit 230, so that the mounting seat 220 bearing the overall weight of the driving unit 230 and the moving unit 240 can realize centering in a preset direction through the elastic buffer units arranged on the two mounting lugs 222, and further the stress of the mounting seat 220 in the preset direction is more uniform, and the movement dislocation of the mounting seat 220 and the moving unit 240 is avoided; and centers the center of gravity of the whole electric shearing device.
