Abstract
Description
Technical Field
[0001] The present application relates to the technical field of hair cleaning, and in particular to a linear motor and a shaver. Background Art
[0002] When an electric shaver is used to cut beard, the motor needs to provide kinetic energy to the blades so that the moving blade and the stationary blade produce relative shearing motion. No matter what kind of motor the electric shaver uses, the vibration generated by the motor itself is difficult to completely eliminate.
[0003] In related technical solutions, electrical connection to the motor is achieved by providing two ends of a cable, such as one end of the cable being directly or indirectly connected to the power supply, and the other end being connected to the motor. On the one hand, the space inside the motor is relatively small, and the length of the connecting cable is relatively short, so the fatigue strength of the connecting cable is lower, making it more prone to fatigue fracture. In addition, the connecting cable is relatively thick, making it difficult to install in a small space. On the other hand, the end of the connecting cable fixed to the motor will vibrate at the same frequency as the motor, while the end directly or indirectly connected to the power supply will not vibrate with the motor. The resulting displacement difference will cause the connecting cable to swing, which can easily loosen the connecting cable electrically connected to the motor, resulting in an unstable electrical connection.

[0054] In the embodiment of the present utility model, see Figures 1 to 3 As shown, the linear motor 1 is described in detail, including a frame 11 for supporting and connecting, etc.; a driving assembly for generating an electromagnetic effect after being energized, the driving assembly including a first driving component 12 and a second driving component 14; a first moving component 13 and a second moving component 15 for reciprocating motion under the influence of the electromagnetic effect of the first driving component 12 and the second driving component 14; an integrated circuit board 16 for conducting electricity; a first cable 17 for connecting to the integrated circuit board 16 and connecting to the first driving component 12, and a second cable 18 for connecting to the integrated circuit board 16 and connecting to the second driving component 14.
[0055] The first driving component 12 and the second driving component 14 are respectively Figures 1 to 3The first and second driving components 12 and 14 are arranged side by side and spaced apart in the front and rear directions inside the frame 11. It should be noted that the first driving component 12 and the second driving component 14 include but are not limited to elastic suspensions arranged inside the frame 11. The first moving component 13 is arranged at the upper end of the first driving component 12, and the first moving component 13 and the first driving component 12 perform reciprocating motion in opposite directions under the electromagnetic action of the first driving component 12, that is, the first driving component 12 and the second driving component 14 respectively move along the direction shown in FIG. Figures 1 to 3 and Figure 10 、 Figure 11 , it should be noted that the first moving component 13 and the second driving component 14 move in opposite directions in real time, such as when the first moving component 13 moves to the left, the first driving component 12 moves to the right. The second moving component 15 is provided at the upper end of the second driving component 14, and the second moving component 15 and the second driving component 14 reciprocate in opposite directions under the electromagnetic action of the second driving component 14, that is, the second moving component 15 and the second driving component 14 move in opposite directions respectively. Figures 1 to 3 and Figure 10 、 Figure 11 It should be noted that the second moving component 15 and the second driving component 14 move in opposite directions in real time. For example, when the second moving component 15 moves to the left, the second driving component 14 moves to the right.
[0056] In such Figure 1 and Figure 2 As shown in , the integrated circuit board 16 is fixedly connected to the lower end of the frame 11. A first fixing position and a second fixing position are respectively provided on the front and rear sides of the integrated circuit board 16. That is, the first fixing position and the second fixing position are provided on both sides of the integrated circuit board 16 along the side-by-side direction of the arrangement of the first drive component 12 and the second drive component 14 in the frame 11, so that the first drive component 12 is opposite to the first fixing position and the second drive component 14 is opposite to the second fixing position. It should be noted that in this embodiment, the first fixing position and the second fixing position can be provided on the same board surface of the integrated circuit board 16, that is, on the upper board surface or the lower board surface of the integrated circuit board 16; the first fixing position and the second fixing position are provided on the upper board surface and the lower board surface of the integrated circuit board 16, respectively. In this embodiment, the first fixing position and the second fixing position are provided on the lower board surface of the integrated circuit board 16 for description and explanation.
[0057] like Figure 1As shown, the two ends of the first cable 17 are respectively connected to the first driving component 12 and the second fixed position, that is, one end of the first cable 17 is connected to the first driving component 12 in the front of the frame 11, and the other end of the first cable 17 is connected to the second fixed position at the rear of the integrated circuit board 16. The two ends of the second cable 18 are respectively connected to the second driving component 14 and the first fixed position, that is, one end of the second cable 18 is connected to the second driving component 14 in the rear of the frame 11, and the other end of the second cable 18 is connected to the first fixed position at the front of the integrated circuit board 16.
[0058] In this embodiment, by making the first fixing position correspond to the first driving component 12, and the second fixing position correspond to the second driving component 14, the two ends of the first cable 17 are respectively connected to the first driving component 12 and the second fixing position, and the two ends of the second cable 18 are respectively connected to the second driving component 14 and the first fixing position, that is, the first cable 17 and the second cable 18 cross-connect the first driving component 12 and the second fixing position and the second driving component 14 and the first fixing position, respectively. Compared with the first cable 17 and the second cable 18 correspondingly connecting the first cable 17 and the first fixing position and the second driving component 14 and the second fixing position, the connection length of the first cable 17 and the second cable 18 is extended, so that the portions of the first cable 17 and the second cable 18 extending along the two ends can absorb or buffer vibration, thereby improving the fatigue strength of the first cable 17 and the second cable 18, making fatigue fracture less likely to occur, and making the connection between the first driving part and the second driving part and the integrated circuit board 16 more stable.
[0059] It should be noted that when the cable is shorter, the stress will be more concentrated when the cable is bent through both ends of the cable, and the cable will be more likely to break at the stress concentrated part, so the fatigue strength is lower; when the cable is longer, the stress will be more dispersed when the cable is bent through both ends of the cable, so the fatigue strength is higher.
[0060] Integrated circuit board 16 is a conductive circuit board with a printed circuit. One end of a first cable 17 is electrically connected to the first drive component 12 at the front of the frame 11, and the other end of the first cable 17 is electrically connected to a second fixed position at the rear of the integrated circuit board 16. One end of a second cable 18 is electrically connected to the second drive component 14 at the rear of the frame 11, and the other end of the second cable 18 is electrically connected to a first fixed position at the front of the integrated circuit board 16. In this embodiment, power is directly supplied to the first and second cables 17, 18 via the integrated circuit board 16, simplifying the structure of the linear motor 1 and facilitating manufacturing.
[0061] In this embodiment, the position of the integrated circuit board 16 is described in detail. The integrated circuit board 16 is located on the side of the driving component away from the moving component, that is, Figure 1 and Figure 2As shown in FIG, the integrated circuit board 16 is at the lower end of the first driving component 12 and the second driving component 14. The board surface of the integrated circuit board 16 is opposite to the end of the first driving component 12 and the second driving component 14 away from the first moving component 13, that is, the upper and lower board surfaces of the integrated circuit board 16 are as shown in FIG. Figure 5 In this embodiment, the upper and lower surfaces of the integrated circuit board 16 are arranged to face the lower ends of the first and second drive components 12 and 14. Compared to the case where the integrated circuit board 16 is arranged offset from the lower ends of the first and second drive components 12 and 14, the upper and lower surfaces of the integrated circuit board 16 are parallel to the lower ends of the first and second drive components 12 and 14. This makes it easier to fix the integrated circuit board 16 when it is electrically connected via the first and second cables 17 and 18, and also improves the appearance of the linear motor 1.
[0062] Furthermore, the first cable 17 has a first bending section 171, and a first connecting section 172 and a second connecting section 173 extending from both ends of the first bending section 171 in a side-by-side direction, the first connecting section 172 is electrically connected to the first driving component 12, and the second connecting section 173 is electrically connected to the second fixed position; the second cable 18 has a second bending section 181, and a third connecting section 182 and a fourth connecting section 183 extending from both ends of the second bending section 181 in a side-by-side direction, the third connecting section 182 is electrically connected to the second driving component 14, and the fourth connecting section 183 is electrically connected to the first fixed position.
[0063] In this embodiment, the first cable 17 and the second cable 18 are described in detail. Figure 9As shown, the first cable 17 has a first bending section 171, and a first connecting section 172 and a second connecting section 173 extending from both ends of the first bending section 171 along the side-by-side direction in which the first driving component 12 and the second driving component 14 are arranged in the frame 11, that is, the first bending section 171 is the bending part when the first cable 17 connects the first driving component 12 and the second fixed position, the first connecting section 172 is an extension part extending from the first bending section 171 and electrically connected to the first driving component 12, and the second connecting section 173 is an extension part extending from the first bending section 171 and electrically connected to the second fixed position. The first connecting section 172 is at the upper end of the first bending section 171, and the second connecting section 173 is at the lower end of the first bending section 171. The second cable 18 has a second bending section 181, and a third connecting section 182 and a fourth connecting section 183 extending from both ends of the second bending section 181 along the side-by-side direction in which the first driving component 12 and the second driving component 14 are arranged in the frame 11, that is, the second bending section 181 is the bending part when the second cable 18 connects the second driving component 14 and the first fixed position, the third connecting section 182 is an extension part extending from the second bending section 181 and electrically connected to the second driving component 14, and the fourth connecting section 183 is an extension part extending from the second bending section 181 and electrically connected to the first fixed position. The third connecting section 182 is at the upper end of the second bending section 181, and the fourth connecting section 183 is at the lower end of the second bending section 181.
[0064] In this embodiment, by cross-connecting the first cable 17 and the second cable 18 to the first driving component 12 and the second fixed position and the second driving component 14 and the first fixed position respectively, compared with the first cable 17 and the second cable 18 correspondingly connecting the first cable 17 and the first fixed position and the second driving component 14 and the second fixed position respectively, the connection length of the first cable 17 and the second cable 18 is extended, so that the fatigue strength of the first cable 17 and the second cable 18 is improved, fatigue fracture is less likely to occur, and the connection between the first driving component 12 and the second driving part and the integrated circuit board 16 is more stable.
[0065] Furthermore, the first cable 17 and the second cable 18 are bent on the same side toward the side-by-side direction, and the extension length of the second connecting segment 173 is greater than the extension length of the fourth connecting segment 183, and / or the extension length of the third connecting segment 182 is greater than the extension length of the first connecting segment 172.
[0066] In this embodiment, the first cable 17 and the second cable 18 are again described in detail. The first cable 17 and the second cable 18 are bent toward the same side of the parallel arrangement direction of the first drive component 12 and the second drive component 14 within the frame 11. That is, the first bent section 171 and the second bent section 181 are both located at the front end or the rear end of the linear motor 1. This embodiment is primarily described with the first bent section 171 and the second bent section 181 located at the front end of the linear motor 1. The second connecting section 173 has a greater extension length than the fourth connecting section 183, that is, the length of the second connecting section 173 at the lower end of the first cable 17 is greater than the extension length of the fourth connecting section 183 at the lower end of the second cable 18, and / or the third connecting section 182 has a greater extension length than the first connecting section 172, that is, the length of the third connecting section 182 at the upper end of the second cable 18 is greater than the extension length of the second connecting section 173 at the upper end of the first cable 17. In this embodiment, by setting the extension length of the second connecting section 173 to be greater than the extension length of the fourth connecting section 183, the second connecting section 173 is electrically connected to the second fixed position, and the fourth connecting section 183 is electrically connected to the first fixed position. The extension length of the third connecting section 182 is greater than the extension length of the first connecting section 172, so that the third connecting section 182 is electrically connected to the second driving component 14, and the first connecting section 172 is electrically connected to the first driving component 12. The first cable 17 and the second cable 18 cross and extend the connection length respectively, so that the fatigue strength of the first cable 17 and the second cable 18 is improved, fatigue fracture is not likely to occur, and the connection between the first driving component 12 and the second driving component 14 and the integrated circuit board 16 is more stable.
[0067] Furthermore, it includes two first cables 17 and two second cables 18 , and the two second bending sections 181 are between the two first bending sections 171 .
[0068] In this embodiment, the first and second cables 17, 18 are described in detail again. The cables are comprised of two first cables 17 and two second cables 18, respectively. It should be noted that while this embodiment describes two first cables 17 and two second cables 18, in practice, more or fewer cables may be included. The two second bends 181 of the two second cables 18 are located between the two first bends 171 of the two first cables 17. The two first cables 17 and two second cables 18 described in this embodiment include, but are not limited to, neutral and live wires, respectively.
[0069] Furthermore, the second connecting section 173 and the third connecting section 182 are correspondingly arranged at the lower end of the second driving component 14 along the first direction, and the first direction intersects with the reciprocating motion direction.
[0070] In this embodiment, the first cable 17 and the second cable 18 are described in detail again. Figure 2As shown in , the second connecting segment 173 at the lower end of the first cable 17 and the third connecting segment 182 at the upper end of the second cable 18 are disposed in correspondence with each other, that is, the second connecting segment 173 and the third connecting segment 182 are both disposed in correspondence with each other at the lower end of the second driving component 14 along a first direction, which in this embodiment is the up-down direction. In this embodiment, the second connecting segment 173 of the first cable 17 and the third connecting segment 182 of the second cable 18 are disposed in correspondence with each other at the lower end of the second driving component 14. This effectively extends the length of the first cable 17 and the second cable 18 when the first connecting segment 172 of the first cable 17 and the fourth connecting segment 183 of the second cable 18 are electrically connected to the first driving component 12 and the first fixing position, thereby increasing the length of the first cable 17 and the second cable 18, thereby improving the fatigue strength of the first cable 17 and the second cable 18, and making them less susceptible to fatigue fracture.
[0071] Furthermore, a clearance notch 161 is provided on one side periphery of the integrated circuit board 16 along the parallel direction, and the first bending section 171 and / or the second bending section 181 are arranged corresponding to the clearance notch 161 .
[0072] In this embodiment, the integrated circuit board 16 is described in detail. A clearance notch 161 is provided on one side of the peripheral edge of the integrated circuit board 16 along the parallel direction of the first driving component 12 and the second driving component 14. Figure 5 、 Figure 6 As shown in FIG, a clearance notch 161 is provided on the front periphery of the integrated circuit board 16. It should be noted that the clearance notch 161 described in this embodiment can be provided on both the front and rear peripheries of the integrated circuit board 16. The placement of the clearance notch 161 is related to the specific positions of the first and second bending sections 171, 181 of the first and second cables. Specifically, when the first and second bending sections 171, 181 are located in front of the linear motor 1, the clearance notch 161 is provided on the front side of the integrated circuit board 16 corresponding to the first and second bending sections 171, 181. Conversely, when the first and second bending sections 171, 181 are located in the rear side of the linear motor 1, the clearance notch 161 is provided on the rear side of the integrated circuit board 16 corresponding to the first and second bending sections 171, 181. In this embodiment, the first and second bending sections 171, 181 are primarily provided on the front side of the linear motor 1 for implementation and description.
[0073] In this embodiment, by providing a avoidance notch 161 on the side edge position of the integrated circuit board 16 corresponding to the first bending section 171 and the second bending section 181, after the first driving component 12 and the first moving component 13 are energized, the first driving component 12 and the first moving component 13 reciprocate in opposite directions (see the above embodiment for details), and after the second driving component 14 and the second moving component 15 are energized, the second driving component 14 and the second moving component 14 reciprocate in opposite directions. When the first cable 17 and the second cable 18 move (refer to the above embodiment for details), the reciprocating motion of the first driving component 12, the first moving component 13, the second driving component 14, and the second moving component 15 will produce a reciprocating displacement difference. Compared with when no corresponding avoidance notch 161 is provided on the integrated circuit board 16, the first bending section 171 of the first cable 17 and the second bending section 181 of the second cable 18 will rub against the peripheral edge of the integrated circuit board 16, causing damage to the first cable 17 and the second cable 18, or causing damage to the first circuit board 124.
[0074] Furthermore, two first fixing positions are provided on the integrated circuit board 16 . The two first fixing positions are respectively provided on both sides of the avoiding notch 161 along the reciprocating motion direction, and the second fixing position is opposite to the avoiding notch 161 .
[0075] In this embodiment, the integrated circuit board 16 is described again. Two first fixing positions are provided on the integrated circuit board 16. The two first fixing positions are respectively provided as follows: Figure 5 、 Figure 6 The avoidance notch 161 shown in FIG is provided on both sides of the reciprocating direction, i.e., two first fixed positions are provided on the left and right sides of the avoidance notch 161, respectively. The second fixed position is provided at a position opposite to the avoidance notch 161 in the parallel direction of the first drive component 12 and the second drive component 14, i.e., at the rear side of the integrated circuit board 16. In this embodiment, by specifically limiting the first and second fixed positions, the second connecting section 173 of the first cable 17 and the fourth connecting section 183 of the second cable 18 are indirectly limited. After the first and second cables 17 and 18 are electrically connected to the integrated circuit board 16, the first bent section 171 of the first cable 17 and the second bent section 181 of the second cable 18 fully correspond to the avoidance notch 161, i.e., fully in front of the avoidance notch 161, to ensure that the first and second cables 17 and 18 do not rub against the integrated circuit board 16 when a reciprocating displacement difference occurs (see above for further beneficial effects).
[0076] Furthermore, it also includes a wire pressing piece 19 fixedly connected to the frame 11 and located at the end of the first driving component 12 away from the first moving component 13, and two wire pressing portions 191 are provided on the side of the wire pressing piece 19 away from the first driving component 12; the integrated circuit board 16 is fixedly arranged on the side of the wire pressing piece 19 where the wire pressing portions 191 are provided, and each wire pressing portion 191 protrudes from the side of the integrated circuit board 16 away from the first driving component 12; each wire pressing portion 191 presses the second connecting section 173 and the fourth connecting section 183 respectively.
[0077] In this embodiment, a wire pressing member 19 is further included, which is fixedly connected to the frame 11 and located at the lower end of the first driving member 12. Figure 1 、 Figure 2 、 Figure 7 As shown, one surface of the upper end of the wire pressing member 19 is fixedly connected to the first driving unit, and two wire pressing portions 191 are provided on one surface of the lower end of the wire pressing member 19. In some embodiments, the two wire pressing portions 191 on one surface of the lower end of the wire pressing member 19 are arranged side by side along the reciprocating direction, that is, the two wire pressing portions 191 are arranged side by side on the left and right sides. The integrated circuit board 16 is fixedly mounted on the surface of the wire pressing member 19 on which the wire pressing portions 191 are provided, that is, the integrated circuit board 16 is mounted on one surface of the lower end of the wire pressing member 19, so that the wire pressing member 19 is between the integrated circuit board 16 and the frame 11, and each wire pressing portion 191 on the lower end of the wire pressing member 19 protrudes from the board surface at the lower end of the integrated circuit board 16. Each wire pressing portion 191 protruding from the lower end of the integrated circuit board 16 respectively presses the second connecting section 173 of the first cable 17 and the fourth connecting section 183 of the second cable 18. It should be noted that when each pressing portion 191 protrudes from the lower end of the integrated circuit board 16, it includes each pressing portion 191 directly passing through the integrated circuit board 16 and then protruding from the board surface of the lower end of the integrated circuit board 16, or each pressing portion 191 surrounds the peripheral edge of the integrated circuit board 16 and then protrudes from the board surface of the lower end of the integrated circuit board 16. In this embodiment, each pressing portion 191 directly passes through the integrated circuit board 16 and then protrudes from the board surface of the lower end of the integrated circuit board 16 for implementation and description.
[0078] In this embodiment, by providing a wire pressing portion 191 on the wire pressing member 19, the second connecting segment 173 and the fourth connecting segment 183 are pre-fixed when the first cable 17 and the second cable 18 are electrically connected to the integrated circuit board 16. Compared with the case where the wire pressing portion 191 is not provided, it is more convenient to pre-fix the second connecting segment 173 and the fourth connecting segment 183 by the wire pressing portion 191 and then electrically connect them to the integrated circuit board 16. After the second connecting segment 173 and the fourth connecting segment 183 are fixedly electrically connected to the integrated circuit board 16, the wire pressing portion 191 can also suppress the second connecting segment 173 and the fourth connecting segment 183, so that the electrical connection between the second connecting segment 173 and the fourth connecting segment 183 and the integrated circuit board 16 is more stable.
[0079] Furthermore, each wire pressing portion 191 is respectively arranged opposite to the first fixing position and the second fixing position; each wire pressing portion 191 is respectively provided with a wire pressing through hole 192 for plugging the first cable 17 and / or the second cable 18.
[0080] In this embodiment, the wire pressing member 19 is described in detail again, see Figure 1 、 Figure 2 、 Figure 3 、 Figure 7 As shown in the figure, the wire pressing portion 191 on the wire pressing member 19 is respectively arranged opposite to the first fixed position and the second fixed position, that is, a wire pressing portion 191 is respectively provided on the left and right sides of the avoidance notch 161 of the integrated circuit board 16, and a wire pressing portion 191 is also provided at the position corresponding to the avoidance notch 161 on the rear side of the integrated circuit board 16. In addition, each wire pressing portion 191 is respectively provided with a wire pressing hole 192 for plugging in the first cable 17 and / or the second cable 18. The second connecting segment 173 of the first cable 17 is plugged into the wire pressing hole 192 on the wire pressing portion 191 corresponding to the second fixed position, thereby pre-fixing the second connecting segment 173 of the first cable 17; the fourth connecting segment 183 of the second cable 18 is plugged into the wire pressing hole 192 on the wire pressing portion 191 corresponding to the first fixed position, thereby pre-fixing the fourth connecting segment 183 of the second cable 18.
[0081] In this embodiment, by providing a pressing portion 191 on the pressing member 19, the second connecting segment 173 and the fourth connecting segment 183 are pre-fixed when the first cable 17 and the second cable 18 are electrically connected to the integrated circuit board 16, and the second connecting segment 173 and the fourth connecting segment 183 are respectively inserted into the corresponding pressing through-holes 192 on the pressing portion 191. Compared with the case where the pressing portion 191 is not provided, it is more convenient to pre-fix the second connecting segment 173 and the fourth connecting segment 183 by the pressing portion 191 and then electrically connect them to the integrated circuit board 16. After the second connecting segment 173 and the fourth connecting segment 183 are fixedly electrically connected to the integrated circuit board 16, the pressing portion 191 can also suppress the second connecting segment 173 and the fourth connecting segment 183, so that the electrical connection between the second connecting segment 173 and the fourth connecting segment 183 and the integrated circuit board 16 is more stable.
[0082] Furthermore, two first fixing positions are provided on the integrated circuit board 16 , and each wire pressing portion 191 is respectively arranged opposite to the two first fixing positions or the two second fixing positions, wherein one wire pressing portion 191 is provided with two wire pressing holes 192 .
[0083] In this embodiment, referring to the above embodiment, two first fixing positions are provided on the integrated circuit board 16, and the two first fixing positions are respectively located on the left and right sides of the avoidance notch 161. Each first fixing position and the second fixing position are respectively provided with a wire pressing portion 191. It should be noted that the configuration described here is that the wire pressing portion 191 protrudes from the integrated circuit board 16. The wire pressing portion 191, which is provided corresponding to the second fixing position on the rear side of the board surface at the lower end of the integrated circuit board 16, is provided with two wire pressing holes 192.
[0084] Furthermore, the integrated circuit board 16 is provided with a position-avoiding hole 162 for each wire pressing portion 191 to pass through. Each wire pressing portion 191 is correspondingly provided with a position-avoiding hole 162 protruding from a side of the integrated circuit board 16 away from the first driving component 12 .
[0085] In this embodiment, the integrated circuit board 16 is provided with a plurality of relief holes 162. Each wire pressing portion 191 of the wire pressing member 19 is formed by penetrating a corresponding relief hole 162 and then protruding from the lower surface of the integrated circuit board 16. In this embodiment, the wire pressing portion 191 directly passes through the integrated circuit board 16 and protrudes from the lower surface of the integrated circuit board 16. This simplifies the structure and occupies less space, compared to a method in which the wire pressing portion 191 extends around the peripheral edge of the integrated circuit board 16 and then protrudes from the lower surface of the integrated circuit board 16. Consequently, the linear motor 1 is smaller in size.
[0086] Furthermore, the integrated circuit board 16 has two conductive parts 163 , which are electrically connected to the integrated circuit board 16 for conducting electricity for the first cable 17 and the second cable 18 .
[0087] In this embodiment, two conductive portions 163 are provided on the integrated circuit board 16. The two conductive portions 163 are electrically connected to the integrated circuit board 16 and are used to provide electrical conductivity to the first cable 17 and the second cable 18. It should be noted that in some embodiments, the two conductive portions 163 are directly electrically connected to the second connecting segments 173 and the second connecting segments 173 of the first cable 17 and the second cable 18. In this embodiment, the two conductive portions 163 are fixedly electrically connected to the integrated circuit board 16 to provide electrical conductivity to the first cable 17 and the second cable 18 via an integrated electrical connection. Compared to a case where the two conductive portions 163 are directly electrically connected to the first cable 17 and the second cable 18, there is no fixed requirement for the position of the conductive portions 163, thus facilitating implementation.
[0088] Furthermore, the first driving component 12 includes a first winding frame 121, a first winding 122, and a first lead 123 extending from the first winding 122; the linear motor 1 also includes a first circuit board 124; the first circuit board 124 is electrically connected and fixed to the first lead 123; the second driving component 14 includes a second winding frame 141, a second winding 142, and a second lead 143 extending from the second winding 142; the linear motor 1 also includes a second circuit board 144; the second circuit board 144 is electrically connected and fixed to the second lead 143; the two ends of the first cable 17 are respectively connected to the first circuit board 124 and the second fixing position, and the two ends of the second cable 18 are respectively connected to the second circuit board 144 and the first fixing position.
[0089] In this embodiment, the first driving component 12 includes a first winding 122 for generating an electromagnetic effect after being energized, a first winding frame 121 for winding the first winding 122, and a first lead 123 extending from the first winding 122. The first lead 123 is used to electrically connect the first winding 122. Figure 1 、 Figure 2 、 Figure 4 As shown in FIG, the first lead 123 is led downward from the winding. The linear motor 1 also includes a first circuit board 124, which is electrically connected and fixed to the first lead 123. The second driving component 14 includes a second winding 142 for generating an electromagnetic effect when energized, a second winding frame 141 for winding the second winding 142, and a second lead 143 led from the second winding 142, the second lead 143 being used to electrically connect the second winding 142, as shown in FIG. Figure 1 、 Figure 2 、 Figure 4 As shown in FIG, the second lead 143 extends downward from the winding. The linear motor 1 also includes a second circuit board 144, which is electrically connected to and secured to the second lead 143. The first connecting segment 172 of the first cable 17 is electrically connected to the first circuit board 124, while the second connecting segment 173 of the first cable 17 is electrically connected to the second fixing point on the integrated circuit board 16. The third connecting segment 182 of the second cable 18 is electrically connected to the second circuit board 144, while the fourth connecting segment 183 of the second cable 18 is electrically connected to the first fixing point on the integrated circuit board 16.
[0090] The first driving component 12 also includes a first base 125 fixedly connected to the first winding frame 121, and a first circuit board 124 is fixedly connected to the side of the first base 125 facing away from the first winding frame 121; the second driving component 14 also includes a second base 145 fixedly connected to the second winding frame 141, and the second circuit board 144 is fixedly connected to the side of the second base 145 facing away from the second winding frame 141.
[0091] In this embodiment, the first driving component 12 also includes a first base 125, which is arranged at the lower end of the first winding frame 121, that is, the first winding frame 121 is arranged on the upper end plate of the first base 125, and the first circuit board 124 is fixedly connected to the side of the first base 125 facing away from the first moving component 13, that is, the first circuit board 124 is connected to the lower end plate of the first base 125, and the first circuit board 124 is between the first winding frame 121 and the integrated circuit board 16; the second driving component 14 also includes a second base 145, which is arranged at the lower end of the second winding frame 141, that is, the second winding frame 141 is arranged on the upper end plate of the second base 145, and the second circuit board 144 is fixedly connected to the side of the second base 145 facing away from the second moving component 15, that is, the second circuit board 144 is connected to the lower end plate of the second base 145, and the second circuit board 144 is between the second winding frame 141 and the integrated circuit board 16.

Compared with the direct electrical connection with the first lead 123 and the second lead 143 through the first connecting section 172 and the third connecting section 182, since the directions of the first connecting section 172 and the second connecting section 173 are in the front and rear directions, and the directions of the first lead 123 and the second lead 143 are in the up and down directions, the directions of the first connecting section 172 and the second connecting section 173 and the first lead 123 and the second lead 143 are crossed, which is not convenient for direct electrical connection. After the first circuit board 124 and the second circuit board 144 are set, the electrical connection direction between the first connecting section 172 and the second connecting section 173 and the first lead 123 and the second lead 143 is changed, making the electrical connection more convenient.
