[0054] The present utility model proposes a motor assembly, and this motor assembly can be used in electric shearing equipment.

[0055] In the embodiments of the present utility model, please refer to Figures 1 to 8, the motor assembly 100 includes a motor bracket 110, two driving components 120, two moving components 130, and a wiring module 140. The two driving components 120 are installed side by side and spaced apart within the motor bracket 110, and the two moving components 130 are respectively arranged on the same side of the two driving components 120; the driving component 120 drives the moving component 130 to reciprocate along a preset direction through electromagnetic action, and the preset direction intersects with the side-by-side direction of the two driving components 120.

[0056] The wiring module 140 includes a first conductive plate 141, a first cable 150, and a second cable 152. The first conductive plate 141 is fixedly connected to the motor bracket 110 and is located at one end of the two driving components 120 facing away from the two moving components 130; the first conductive plate 141 has a first plate surface 142 facing the motor bracket 110 and a second plate surface 143 facing away from the motor bracket 110; both ends of the first cable 150 are electrically connected to one of the driving components 120 and the first plate surface 142 respectively, and both ends of the second cable 152 are electrically connected to the other driving component 120 and the second plate surface 143 respectively.

[0057] In this embodiment, the motor assembly 100 includes two driving components 120 and two moving components 130, so the electric shearing device applying the motor assembly 100 is driven by two motors, which can effectively improve the shearing efficiency. The motor bracket 110 is used to provide support and protection for the internal structures of the motor such as the driving component 120 and the moving component 130. The two driving components 120 can be fixedly installed within the motor bracket 110, or can be suspended within the motor bracket 110 through structures such as a base and elastic pieces. In this way, the driving component 120 and the moving component 130 can move relative to each other to buffer the vibration of the driving component 120 and the moving component 130, reduce the vibration transmitted to the motor bracket 110, and thus weaken the vibration sensation of the motor assembly 100. The moving component 130 can be specifically suspended and connected to the motor bracket 110 or the base through elastic pieces, flexible pieces, etc.

[0058] It can be understood that the moving component 130 includes a permanent magnet and a connecting seat, and the permanent magnet is fixed on the connecting seat, and the connecting seat forms the output end of the motor. The driving component 120 includes an iron core, a winding frame, and a coil 123 wound around the winding frame, and the winding frame is installed on the iron core. The iron core can be a U-shaped iron core, an E-shaped iron core, etc., and different types of iron cores can be selected according to actual needs, and no specific limitation is made here. After the coil 123 passes through a current with alternating positive and negative directions, the driving component 120 forms an electromagnet with a changing magnetic field, and drives the moving component 130 to reciprocate along a preset direction through the magnetic induction action between the electromagnet and the permanent magnet of the moving component 130.

[0059] The driving component 120 is used to drive the moving component 130 to reciprocate in a preset direction, and the motor is a linear motor. The moving directions of the two moving components 130 can be the same or opposite. Optionally, the moving directions of the two moving components 130 are opposite. In this way, the vibrations generated by the two moving components 130 can partially cancel each other out, thereby weakening the vibration of the entire motor assembly 100. The two moving components 130 can be arranged below the two driving components 120 or above the two driving components 120. If the preset direction intersects with the side-by-side direction of the two driving components 120, then, in order to reduce the space occupation, optionally, the preset direction is perpendicular to the side-by-side direction of the two driving components 120.

[0060] The first conductive plate 141 refers to a conductive structure that is basically plate-shaped. The first conductive plate 141 can be a regular plate shape such as a circle or a rectangle, or an irregular plate shape with a notch or the like. The first conductive plate 141 can be directly fixed to the motor bracket 110, or can be indirectly fixed to the motor bracket 110 through structures such as a fixing plate 163. Specifically, the first cable 150 and the second cable 152 are respectively electrically connected to the coils 123 of the two driving components 120. The first cable 150 and the second cable 152 can be directly electrically connected to the lead-out ends 124 of the coils 123, or can be electrically connected through a conductive plate or other conductive structures. The two ends of the first cable 150 and the second cable 152 are respectively electrically connected to the first plate surface 142 and the second plate surface 143, and the first cable 150 and the first plate surface 142, and the second cable 152 and the second plate surface 143 can be electrically connected by welding or other conductive parts 170. The electrical connection methods of the first cable 150 and the first plate surface 142, and the second cable 152 and the second plate surface 143 can be the same or different. Specifically, one end of the first cable 150 is welded to the first plate surface 142, and one end of the second cable 152 is welded to the second plate surface 143. In this way, it is convenient to operate while ensuring the strength of the electrical connection.

[0061] It should be noted here that the first conductive plate 141 can be a single plate, that is, both the first cable 150 and the second cable 152 are electrically connected to the same first conductive plate 141; the first conductive plate 141 in this application can also be arranged as two spliced or spaced-apart plates, so that the first cable 150 and the second cable 152 are respectively electrically connected to the two first conductive plates 141.

[0062] It can be understood that the first cable 150 and the second cable 152 generally adopt flexible wires, which are convenient for bending, wiring, and can buffer and absorb the vibration of the driving component 120. The first conductive plate 141 has a greater hardness compared to the first cable 150 and the second cable 152, and the first conductive plate 141 has a large and flat plate surface. By electrically connecting both the first cable 150 and the second cable 152 to the plate surface of the first conductive plate 141, on the one hand, the first conductive plate 141 has a large contact area, which is more convenient for the wiring operation of the cables, and the first conductive plate 141 occupies a small space in the thickness direction, enabling both the first cable 150 and the second cable 152 to be electrically connected to the plate surface of the first conductive plate 141, effectively reducing the space occupied by the lead structure in the height direction of the motor assembly 100, which is beneficial to the miniaturization of the motor assembly 100.

[0063] If both the first cable 150 and the second cable 152 are electrically connected to the first plate surface 142 of the first conductive plate 141, the middle space of the first plate needs to be occupied. Thus, in order to facilitate wiring, it is necessary to make the distance between the first plate surface 142 and the motor bracket 110 relatively large, which will increase the space occupied by the wiring structure in the height direction of the motor assembly 100 and is not conducive to the miniaturization of the motor assembly 100. If both the first cable 150 and the second cable 152 are electrically connected to the second plate surface 143 of the first conductive plate 141, the middle space of the second plate surface 143 needs to be occupied. Thus, when the motor assembly 100 is assembled inside the electric shearing device, other components (such as the charging component 400) cannot be adjacent to the second plate surface 143, which is not conducive to reducing the height of the electric shearing device.

[0064] The motor assembly 100 of the utility model can improve the shearing efficiency by setting up a dual driving component 120 and a moving component 130, and can effectively weaken the vibration when the moving directions of the two moving components 130 are opposite. At the same time, by setting a first conductive plate 141 on the motor bracket 110, the first conductive plate 141 is located on the side of the driving component 120 away from the moving component 130, and the first conductive plate 141 has a first plate surface 142 facing the motor bracket 110 and a second plate surface 143 away from the motor bracket 110, so that the two ends of the first cable 150 are respectively electrically connected to one of the driving components 120 and the first plate surface 142, and the two ends of the second cable 152 are respectively electrically connected to the other driving component 120 and the second plate surface 143. That is, by electrically connecting the first cable 150 and the second cable 152 through the first conductive plate 141, the difficulty of cable alignment can be greatly reduced, so as to improve the convenience of cable wiring operation. The first cable 150 and the second cable 152 are electrically connected to two opposite surfaces of the first conductive plate 141, respectively. Compared with arranging the first cable 150 and the second cable 152 on the same surface of the first conductive plate 141, the space occupied by the wiring module 140 in the height direction of the motor assembly 100 can be reduced, thereby making the layout of the motor assembly 100 in the height direction more compact, thereby reducing the height dimension of the motor assembly 100, which is conducive to miniaturization of the motor assembly 100.

[0065] In one embodiment, if Figures 3 to 8 As shown, one end of the first cable 150 connected to the first board surface 142 and one end of the second cable 152 connected to the second board surface 143 are arranged opposite to each other. This layout helps to ensure that the first cable 150 and the second cable 152 are more stable during welding or connection, reducing electrical failures caused by poor contact, and the relative position layout enables the cables to disperse stress when subjected to force, thereby improving the strength and reliability of the connection point. In addition, the relative position lead layout can help the diffusion and convection of heat, improve heat dissipation efficiency, avoid the formation of local hot spots in certain areas, and reduce the risk of damage to components due to overheating.

[0066] For further information, please refer to Figures 1 to 8 The wiring module 140 also includes a wire crimping device 160, which has a first wire crimping portion 161 located on the first board surface 142 and a second wire crimping portion 162 located on the second board surface 143; the first wire crimping portion 161 and the second wire crimping portion 162 are arranged opposite to each other; one end of the first cable 150 is pressed onto the first board surface 142 through the first wire crimping portion 161, and one end of the second cable 152 is pressed onto the second board surface 143 through the second wire crimping portion 162.

[0067] In the present embodiment, it is understandable that the wire presser 160 is made of insulating material. The first wire presser 161 and the second wire presser 162 can be connected to each other and penetrate the first conductive plate 141, or the first wire presser 161 and the second wire presser 162 can be unconnected and separately arranged on both sides of the surface of the first conductive plate 141. The first wire presser 161 and the second wire presser 162 are used to pre-position and limit the connection ends of the first cable 150 and the second cable 152 with the first conductive plate 141, respectively, so that the connection ends of the first cable 150 and the second cable 152 are kept in a position adjacent to the electrical connection with the first conductive plate 141, which can avoid the displacement of the first cable 150 and the second cable 152 during welding, and facilitate the electrical connection operation between the first cable 150, the second cable 152 and the first conductive plate 141. At the same time, since the electrical connection ends of the first cable 150 and the second cable 152 and the first conductive plate 141 are clamped by the first wire pressing portion 161 and the second wire pressing portion 162, the electrical connection ends of the first cable 150 and the second cable 152 and the first conductive plate 141 can be maintained in the connection position, thereby avoiding the connection point from falling off due to long-term vibration.

[0068] The first wire pressing part 161 and the second wire pressing part 162 can have many structures. For example, the first wire pressing part 161 and the second wire pressing part 162 can be specifically wire pressing blocks, and holes are set on the wire pressing blocks for cables to pass through, thereby realizing the cable being pressed against the board surface of the first conductive plate 141. The specific structure of the wire pressing device 160 can be selected and designed according to actual needs, and is not specifically limited here.

[0069] In one embodiment, if Figures 6 to 8 As shown, the wire crimper 160 further includes a fixing plate 163 fixedly connected to the first wire crimping portion 161 , the fixing plate 163 is fixedly connected to the motor bracket 110 , and the first conductive plate 141 is fixedly connected to a side of the fixing plate 163 away from the motor bracket 110 .

[0070] In this embodiment, the fixing plate 163 can be fixedly connected to the motor bracket 110 through structures such as screws. The first conductive plate 141 can also be fixedly connected to the fixing plate 163 by screws. Optionally, the motor assembly 100 further includes a connecting member that sequentially passes through the first conductive plate 141 and the fixing plate 163 and is fixedly connected to the motor bracket 110. In this way, the first conductive plate 141, the fixing plate 163, and the motor bracket 110 can be connected simultaneously through this connecting member, which can simplify the fixed connection structure of the three. Optionally, the fixing plate 163 is provided at least corresponding to the electrical connection ends of the first cable 150, the second cable 152, and the driving component 120. The fixing plate 163, the first cable fixing portion, and the second cable fixing portion are all made of insulating materials. The first conductive plate 141 is fixedly connected to the side of the fixing plate 163 facing away from the motor bracket 110, and the fixing plate 163 is provided at least corresponding to the electrical connection ends of the first cable 150, the second cable 152, and the driving component 120. That is, by separating the motor bracket 110 and the first conductive plate 141 through the fixing plate 163, it can be avoided that one end of the first cable 150 and the second cable 152 in electrical connection with the driving component 120 contacts the first conductive plate 141, causing a short circuit, thereby reducing potential safety hazards and improving the safety and reliability of product use.

[0071] Further, please refer to Figures 1 to 3 , Figures 5 to 8 , on both sides of the fixing plate 163 in a preset direction, a first wire pressing portion 161 and a second wire pressing portion 162 are respectively connected; there are two first cables 150 and two second cables 152, and one ends of the two first cables 150 are respectively pressed against the first plate surface 142 through the two first wire pressing portions 161, and one ends of the two second cables 152 are respectively pressed against the second plate surface 143 through the two second wire pressing portions 162. The two first cables 150 / the two second cables 152 are respectively a positive wire and a negative wire. The first wire pressing portion 161 and the second wire pressing portion 162 corresponding to both sides of the plate surface of the first conductive plate 141 are connected to each other. And by fixing the two first wire pressing portions 161 and the two second wire pressing portions 162 to the motor bracket 110 through the fixing plate 163, the installation of the wire pressing device 160 can be simplified.

[0072] In one embodiment, as Figure 2 , Figures 4 to 8 shown, the two driving components 120 are movably connected to the motor bracket 110 to make the corresponding driving component 120 and the moving component 130 perform relative reciprocating motion under the electromagnetic action;

[0073] The two driving components 120 include a first driving component 121 and a second driving component 122;

[0074] One end of the first cable 150 is electrically connected to the first driving component 121, and the other end is electrically connected to the position of the second driving component 122 corresponding to the first plate surface 142;

[0075] One end of the second cable 152 is electrically connected to the second driving component 122, and the other end is electrically connected to the position on the second board surface 143 corresponding to the first driving component 121.

[0076] In this embodiment, the two driving components 120 are movably connected to the motor bracket 110. Specifically, the motor assembly 100 further includes two bases and a plurality of elastic members. The first driving component 121 and the second driving component 122 are respectively fixedly installed on the two bases, such that both ends of each base are connected to the motor bracket 110 through at least one elastic member. In this way, the two driving components 120 are suspended and connected within the motor bracket 110 and can move within the motor bracket 110. In this way, after being powered on, when the driving component 120 drives the moving component 130 to reciprocate, the driving component 120 can also make a reverse reciprocating motion relative to the moving component 130. In this way, the vibration of the entire motor assembly 100 can be reduced, thereby weakening the vibration sensation of the whole machine.

[0077] One end of the first cable 150 is electrically connected to the first driving component 121, and the other end is electrically connected to the position on the first board surface 142 corresponding to the second driving component 122. Compared with the way that the first cable 150 is electrically connected to the position at one end of the first board surface 142 corresponding to the first driving component 121, when the bending section lengths of the first cable 150 are basically the same, the length of the first cable 150 extending along the board surface of the first conductive plate 141 can be extended. In this way, the part of the first cable 150 extending along the board surface of the first conductive plate 141 can absorb or buffer vibration and disperse stress. Furthermore, the stress concentrated at the bending section of the first cable 150 can be avoided, so as to relieve the stress fatigue of the first cable 150 caused by long-term vibration along with the driving component 120, and greatly increase the service life of the first cable 150.

[0078] Similarly, one end of the second cable 152 is electrically connected to the second driving component 122, and the other end is electrically connected to the position on the second board surface 143 corresponding to the first driving component 121. Compared with the way that the second cable 152 is electrically connected to the position at one end of the second board surface 143 corresponding to the second driving component 122, when the bending section lengths of the second cable 152 are basically the same, the length of the second cable 152 extending along the board surface of the first conductive plate 141 can be extended. In this way, the part of the second cable 152 extending along the board surface of the first conductive plate 141 can absorb or buffer vibration and disperse stress. Furthermore, the stress concentrated at the bending section of the second cable 152 can be avoided, so as to relieve the stress fatigue of the second cable 152 caused by long-term vibration along with the driving component 120, and greatly increase the service life of the second cable 152.

[0079] In addition, the first cable 150 is electrically connected to the position on the first board surface 142 corresponding to the second driving component 122; the second cable 152 is electrically connected to the position on the second board surface 143 corresponding to the first driving component 121, greatly extending the length of the cable along the board surface, which is more convenient for the first cable pressing part 161 and the second cable pressing part 162 to press and connect the first cable 150 and the second cable 152.

[0080] In one embodiment, please refer to Figures 5 to 8 , the first conductive plate 141 has an installation notch 144 provided corresponding to the gap between the first driving component 121 and the second driving component 122, and the first cable pressing part 161 and the second cable pressing part 162 are provided corresponding to the installation notch 144.

[0081] That is, the first cable pressing part 161 and the second cable pressing part 162 are arranged at the middle position of the first conductive plate 141 in the side-by-side direction. On the one hand, it can balance the center of gravity of the entire motor assembly 100, and on the other hand, it makes the pressing positions of the first cable pressing part 161 on the first cable 150 and the second cable pressing part 162 on the second cable 152 basically the same, so as to ensure the electrical connection stability of the first cable 150 and the second cable 152. Optionally, the first cable pressing part 161 and the second cable pressing part 162 are connected through the installation notch 144. In this way, the first cable pressing part 161 and the second cable pressing part 162 can be connected as a whole, which is more convenient for modular assembly and can simplify the installation structure and steps. Further, the first cable pressing part 161 is provided with a first fixing hole for the first cable 150 to pass through, and the second cable pressing part 162 is provided with a second fixing hole for the second cable 152 to pass through. The first fixing hole is arranged adjacent to the first driving component 121, and the second fixing hole is arranged adjacent to the second driving component 122. In this way, the position where the first cable fixing part fixes the first cable 150 is closer to the electrical connection point of the first cable 150, and the position where the second fixing part fixes the second cable 152 is closer to the electrical connection point of the second cable 152, so as to ensure the strength and reliability of the electrical connection points of the first cable 150 and the second cable 152 with the first conductive plate 141.

[0082] Further, please refer to Figure 4 and Figure 8 , one end of the first cable 150 is welded to the position on the first board surface 142 corresponding to the second driving component 122 to form a first welding point, and one end of the second cable 152 is welded to the position on the second board surface 143 corresponding to the first driving component 121 to form a second welding point. The first welding point and the second welding point are located on both sides of the installation notch 144 in the side-by-side direction. In this way, the welding points between the first cable 150 and the first conductive plate 141, and between the second cable 152 and the first conductive plate 141 are arranged staggeredly in the side-by-side direction, which can further ensure the connection stability of the first cable 150 and the second cable 152 with the first conductive plate 141.

[0083] In one embodiment, please refer back to Figure 2 and Figures 5 to 8 . Both the first cable 150 and the second cable 152 have two. One end of the two first cables 150 is respectively connected to both sides of the first plate surface 142 in a preset direction, and one end of the two second cables 152 is respectively connected to both sides of the second plate surface 143 in a preset direction. In this way, the two first cables 150 and the two second cables 152 are respectively connected to both ends of the first conductive plate 141 in a preset direction, which is more convenient for the wiring operation of the wiring personnel, and can also prevent the second cable 152 connected to the second plate surface 143 from affecting the assembly of other components of the electric shearing device (such as the charging component 400). In addition, the lengths and arcs of the bent sections of the first cable 150 and the second cable 152 are made larger, which can disperse the stress and avoid stress concentration, further alleviating the stress fatigue of the first cable 150 and the second cable 152 caused by long-term vibration with the driving component 120, so as to improve the service life of the first cable 150 and the second cable 152.

[0084] In one embodiment, as Figures 1 to 8 shown, the wiring module 140 further includes a conductive member 170 protruding from the middle of the second plate surface 143 in a preset direction. The conductive member 170 is electrically connected to the first conductive plate 141 to electrically connect the first cable 150, the second cable 152 and the power supply. The conductive member 170 can specifically be a conductive column 171 protruding from the second plate surface 143, or a conductive cylinder embedded in the second plate surface 143, or other conductive structures. By making full use of the middle space of the second plate surface 143 to arrange the conductive member 170, the overall layout is more reasonable and compact. And the two driving components 120 can be electrically connected to the power supply only through the conductive member 170 on the first conductive plate 141, which can reduce the difficulty of electrically connecting the driving component 120 to the power supply and improve the electrical connection efficiency.

[0085] Furthermore, please refer to Figure 2 and Figure 5 and Figure 14 . The conductive member 170 includes two conductive columns 171, and the two conductive columns 171 are respectively arranged on both sides of the first conductive plate 141 in a side-by-side manner. In this way, when the motor assembly 100 is installed in the housing 200 of the electric shearing device, components such as the charging component 400 in the housing 200 can be partially accommodated between the two conductive columns 171, making the overall structure of the machine compact. Specifically, an accommodation area 180 for accommodating the charging component 400 is formed by enclosing the second plate surface 143, the second wire pressing part 162 and the two conductive columns 171. Then the charging component 400 can be closer to the first conductive plate 141, making the overall structure of the machine compact, reducing the occupied space of the entire electric shearing device in the height direction, and thus being beneficial to the miniaturization of the electric shearing device.

[0086] In one embodiment, please refer to Figures 5 to 8 , the wiring module 140 further includes a second conductive plate 191 and a third conductive plate 192. The second conductive plate 191 and the third conductive plate 192 are respectively fixedly connected to one ends of the two driving components 120 away from the moving component 130; both of the two driving components 120 include coils 123, and the lead-out ends 124 of the coils 123 of the two driving components 120 are respectively electrically connected to the corresponding second conductive plate 191 and third conductive plate 192; one ends of the two first cables 150 and the two second cables 152 are respectively electrically connected to the second conductive plate 191 and the third conductive plate 192.

[0087] In this embodiment, the second conductive plate 191 and the third conductive plate 192 refer to conductive structures that are basically plate-shaped. The second conductive plate 191 and the third conductive plate 192 can be regular plate shapes such as rectangular or circular, or can be irregular plate shapes. The shapes and sizes of the second conductive plate 191 and the third conductive plate 192 can be the same or different, and no specific limitation is made here.

[0088] To improve the connection stability, specifically, through holes can be provided on the second conductive plate 191 and the third conductive plate 192, and the lead-out end 124 is passed through and welded to the through hole. By electrically connecting the first cable 150 / second cable 152 and the coil 123 through the second conductive plate 191 / third conductive plate 192, compared with directly welding the cable to the lead-out end 124 of the coil 123, the conductive plate can provide a larger and flat surface, which can support the cable, improve the strength and reliability of the electrical connection point of the cable, and at the same time make the cable have a larger contact area with the conductive plate, making it more convenient for the cable wiring operation. To further reduce the wiring difficulty, optionally, the two first cables 150 are welded to the plate surface of the second conductive plate 191 facing the first conductive plate 141, and the two second cables 152 are welded to the plate surface of the third conductive plate 192 facing the first conductive plate 141. Of course, wire fixing clips can also be provided to fix one ends of the first cable 150 and the second cable 152 connected to the second conductive plate 191 and the third conductive plate 192.

[0089] Furthermore, as Figures 1 to 3 、 Figures 5 to 8 shown, both the second conductive plate 191 and the third conductive plate 192 correspond to the middle of the first plate surface 142 in a preset direction. In this way, the gravity distribution is more uniform, and the lengths of the two first cables 150 and the lengths of the two second cables 152 can be basically kept the same, so as to reduce the wiring difficulty and make the lead wire layout of the entire wiring module 140 more regular.

[0090] In one embodiment, please refer to again Figures 1 to 3 、 Figures 5 to 8, the first cable 150 has a first bent section 151 and first extension sections 154 and second extension sections 156 connected to both ends of the first bent section 151; the second cable 152 has a second bent section 153 and third extension sections 155 and fourth extension sections 157 connected to both ends of the second bent section 153;

[0091] The first bent section 151 and the second bent section 153 are located on both sides of the first conductive plate 141 in the side-by-side direction, that is, the bending openings of the first bent section 151 and the second bent section 153 are oppositely arranged; the first extension section 154 extends along the first plate surface 142 and is electrically connected to the first plate surface 142, and the second extension section 156 extends along the second conductive plate 191 and is electrically connected to the second conductive plate 191; the third extension section 155 extends along the second plate surface 143 and is electrically connected to the second plate surface 143, and the fourth extension section 157 extends along the third conductive plate 192 and is electrically connected to the third conductive plate 192.

[0092] In this embodiment, both the first cable 150 and the second cable 152 have bent sections, which can change the electrical connection direction between the cable and the conductive plate. And the first bent section 151 and the second bent section 153 are located on both sides of the first conductive plate 141 in the side-by-side direction, avoiding overcrowding when both the first bent section 151 and the second bent section 153 are located on one side of the first conductive plate 141, reducing the wiring difficulty, and making the lead layout of the entire wiring module 140 more regular. And both ends of the bent section have extension sections. The first extension section 154 extends along the first plate surface 142, and the second extension section 156 extends along the second conductive plate 191; the third extension section 155 extends along the second plate surface 143, and the fourth extension section 157 extends along the third conductive plate 192, which is more convenient for the wiring operation of the first cable 150 with the first conductive plate 141 and the second conductive plate 191, and for the wiring operation of the second cable 152 with the first conductive plate 141 and the third conductive plate 192. At the same time, it can also increase the fitting contact area between the first cable 150, the second cable 152 and each conductive plate, so as to further improve the connection stability between the first cable 150, the second cable 152 and each conductive plate.

[0093] Further, the first extension section 154, the second extension section 156, the third extension section 155, and the fourth extension section 157 all extend along the side-by-side direction. In this way, the dimensions of the first cable 150 and the second cable 152 in the preset direction can be reduced, making the overall cable layout more reasonable and compact. In addition, since the driving component 120 drives the moving component 130 to reciprocate along the preset direction through electromagnetic action, the entire motor assembly 100 will generate reciprocating vibrations along the preset direction. Making the first extension section 154, the second extension section 156, the third extension section 155, and the fourth extension section 157 all extend along the side-by-side direction can also improve the stability of the connection points between the extension sections and the conductive plates.

[0094] Further, the first bending section 151 and the second bending section 122 are bent toward different sides of the side-by-side direction.

[0095] If the first bending section 151 and the second bending section 153 are bent toward the same side of the side-by-side direction, it is necessary to make the parts of the first cable 150 and the second cable 152 between the motor bracket 110 and the first conductive plate 141 be vertically offset. In this way, the occupied space of the lead structure in the height direction of the motor assembly 100 will be increased. By making the first bending section 151 of the first cable 150 and the second bending section 153 of the second cable 152 be bent toward different sides of the side-by-side direction, the parts of the first cable 150 and the second cable 152 between the motor bracket 110 and the first conductive plate 141 can be arranged side by side along the plate surface, and thus the space in the height direction of the motor assembly 100 will not be additionally occupied, the layout of the motor assembly 100 in the height direction can be made more compact, and further the height dimension of the motor assembly 100 can be reduced, which is beneficial to the miniaturization of the motor assembly 100.

[0096] Even further, as Figure 2 、 Figures 4 to 8 shown, the first bending section 151 is bent toward the second driving component 122; the second bending section 153 is bent toward the first driving component 121.

[0097] In this embodiment, making the first bending section 151 be bent toward the second driving component 122, compared with the way that the first bending section 151 is bent away from the second driving component 122, makes the first bending section 151 mostly located on the outside, rather than being clamped between the motor bracket 110 and the first conductive plate 141. While reducing the height dimension of the motor assembly 100, it can avoid interference between the first cable 150 and other components. In addition, bending the first bending section 151 toward the second driving component 122 can increase the length of the first extension section 154. In this way, the contact length and area between the first cable 150 and the first plate surface 142 can be increased, further improving the strength and reliability of the electrical connection point between the first cable 150 and the first plate surface 142.

[0098] Similarly, the second bent section 153 is bent towards the first driving component 121. Compared with the way that the second bent section 153 is bent away from the first driving component 121, the second bent section 153 is mostly located outside, rather than being clamped between the motor bracket 110 and the first conductive plate 141, which can avoid interference between the second cable 152 and other components while reducing the height dimension of the motor assembly 100. In addition, bending the second bent section 153 towards the first driving component 121 can increase the length of the third extension section 155. In this way, the contact length and area between the second cable 152 and the second plate surface 143 can be increased, further improving the strength and reliability of the electrical connection point between the second cable 152 and the second plate surface 143.

[0099] In one embodiment, the first conductive plate 141 has a first avoidance notch 145 corresponding to a part of the first bent section 151 and a second avoidance notch 146 corresponding to and accommodating a part of the second bent section 153. In this way, while reducing the overall weight, it can avoid the first bent section 151 and the second bent section 153 colliding with and rubbing against the first conductive plate 141 and breaking due to the long-term vibration of the motor assembly 100.

[0100] The present utility model also provides an electric shearing device, such as Figures 9 to 14 shown. The electric shearing device includes a housing 200, a cutter head assembly 300, and a motor assembly 100. The specific structure of the motor assembly 100 refers to the above embodiments. The motor assembly 100 is installed in the housing 200, and the cutter head assembly 300 is connected to the moving component 130 of the motor assembly 100. Since the electric shearing device adopts all the technical solutions of the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated here one by one.

[0101] The electric shearing device may specifically be an electric shaver. The shape of the housing 200 can be selected and designed according to actual needs, and no specific limitation is made here. The cutter head assembly 300 specifically includes at least two cutter heads, and each cutter head includes a moving cutter and a stationary cutter covering the outside of the moving cutter. The multiple cutter heads can all be set as long-beard cutter heads, short-beard cutter heads, or some are long-beard cutter heads and some are short-beard cutter heads. The two moving components are respectively connected to the moving cutters of at least two cutter heads to drive the moving cutters to reciprocate relative to the stationary cutters along a preset direction to cut hair.

[0102] In one embodiment, please refer to Figures 10 to 14 again. The housing 200 includes a housing body 210 and an end cover 220. The housing body 210 has an opening 211, and the end cover 220 is installed at the opening 211. The motor assembly 100 is installed in the housing body 210, and the motor bracket 110 is fixedly connected to the end cover 220.

[0103] The bottom wall of the housing 210 facing the opening 211 is provided with a charging assembly 400;

[0104] The electric shearing device further includes a movement support 500 provided in the housing 210. The movement support 500 has a receiving cavity 510 for receiving the motor assembly 100. A battery 600 is provided on the movement support 500. A first conductive part 520 facing the motor support 110 and a second conductive part 530 facing the charging assembly 400 are provided on the movement support 500. The first conductive part 520 and the second conductive part 530 are electrically connected to the battery 600;

[0105] The first conductive plate 141 of the motor assembly 100 is electrically connected to the first conductive part 520, and the second conductive part 530 is electrically connected to the charging assembly 400.

[0106] In this embodiment, the end cover 220 can be fixedly connected to the housing 210 through structures such as screws. The motor support 110 is fixedly connected to the end cover 220 and is received in the receiving cavity 510 of the movement support 500. That is, the motor assembly 100 is suspended relative to the housing 210 and the movement, which can avoid the vibration of the motor assembly 100 being transmitted into the housing 210, and further reduce the holding vibration feeling of the electric shearing device.

[0107] During assembly, the motor assembly 100 can be installed into the housing 210 together with the end cover 220. Further, the movement support 500 is also fixedly connected to the inner side surface of the end cover 220. In this way, after the motor assembly 100 is connected to the end cover 220, the movement support 500 loaded with the battery 600 can be installed on the end cover 220 to form the entire installation module. Finally, the entire installation module such as the end cover 220, the movement support 500 loaded with the battery 600, and the motor assembly 100 can be installed into the inner cavity of the housing 210 through the opening 211. Only by fixedly connecting the end cover 220 and the housing 210 can the assembly of the main body of the electric shearing device be realized. That is, in this embodiment, the pre-assembly of the movement support 500, the motor assembly 100, and the battery 600 is realized through the end cover 220, and the above structures can be modularly assembled into the housing 210 as a whole, which can simplify the installation and is beneficial to improving the overall assembly efficiency of the machine.

[0108] The charging component 400 is used to connect to an external power source to charge the battery 600. By providing a first conductive portion 520 on the movement bracket 500 facing the motor bracket 110 and a second conductive portion 530 facing the charging component 400, when the motor assembly 100 is received in the receiving cavity 510 of the movement bracket 500, the first conductive plate 141 can be electrically connected to the first conductive portion 520 of the movement bracket 500, and when the movement bracket 500 is installed in the housing 210, the second conductive portion 530 on the movement bracket 500 can be electrically connected to the charging component 400 of the housing 210. In this way, rapid electrical connection among the charging component 400, the power source on the movement bracket 500, and the motor assembly 100 can be achieved, which can greatly simplify the electrical connection steps and improve the assembly efficiency of the whole machine. The first conductive portion 520 and the second conductive portion 530 can specifically be conductive cylinders, and conductive posts 171 can be provided on the first conductive plate 141 and the circuit board of the charging component 400 to achieve electrical connection.

[0109] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
