Abstract
Description
Technical Field
[0001] The present application relates to the technical field of hair cleaning, and particularly relates to a linear motor and a razor. Background Art
[0002] When cutting beards with an electric razor, kinetic energy needs to be provided to the blade by a motor to cause relative shearing movement between the moving blade and the static blade. No matter what kind of motor the electric razor uses, it is difficult to completely eliminate the vibration generated by the motor itself during operation.
[0003] In related technical solutions, two circuit boards are provided to realize the electrical connection of the motor. One circuit board is fixedly connected to the motor, and the other circuit board is fixed relative to the motor. The two circuit boards are connected by a cable, and the motor is powered after one of the circuit boards is powered. On the one hand, the space between the two circuit boards is small, and the connecting cable is relatively thick and not easy to bend, so it is not convenient to install the two circuit boards and the cable; on the other hand, the circuit board fixed to the motor will vibrate at the same frequency as the motor, while the circuit board fixed relative to the motor will not vibrate with the motor. Therefore, the two circuit boards will generate a displacement difference when the motor vibrates, causing the cable to swing between the two circuit boards. This swing easily loosens the cable electrically connected to the motor, resulting in unstable electrical connection.

[0053] In an embodiment of the present utility model, the linear motor 100 includes a driving component 120 for generating an electromagnetic effect after the linear motor 100 is powered on, a moving component 130 for reciprocating movement under the electromagnetic effect of the driving component 120, a cable 140 for conducting electricity, a first circuit board 150 fixed to the driving component 120, a second circuit board 160 fixed to the frame 110 through the mounting bracket 190, and a first wire pressing component 170 and a second wire pressing component 180 for respectively fixing the first end 141 and the second end 142 of the cable 140 to the first circuit board 150 and the second circuit board 160.

[0055] The linear motor 100 provided by an embodiment of the present utility model has a driving component 120 and a moving component 130 disposed within a frame 110. The driving component 120 is connected to the frame 110 through a first elastic member 126, and the moving component 130 is connected to the driving component 120 through a second elastic member 131. The first end 141 of a cable 140 is electrically connected to a first circuit board 150 on the driving component 120 and the first end 141 of the cable 140 is fixed by a first wire pressing member 170. The second end 142 of the cable 140 is electrically connected to a second circuit board 160 on the frame 110 and the second end 142 of the cable 140 is fixed by a second wire pressing member 180. When the linear motor 100 is operating, due to the fixing of the first end 141 and the second end 142 of the cable 140 by the first wire pressing member 170 and the second wire pressing member 180, even if the driving component 120 and the moving component 130 vibrate, it will not affect the connection between the cable 140 and the first circuit board 150 and the second circuit board 160, reducing the possibility of the cable 140 becoming loose.
[0056] Furthermore, the first circuit board 150 and the first wire pressing member 170 are fixedly connected to the driving component 120. The first end 141 of the cable 140 is electrically connected to the first circuit board 150, and the first wire pressing member 170 fixes the first end 141 of the cable 4 to the first circuit board 150. Specifically, the first wire pressing member 170 is fixedly connected to the driving component 120, and the upper end surface of the first wire pressing member 170 abuts against the lower end surface of the driving component 120; the first circuit board 150 is fixedly connected to the other surface of the first wire pressing member 170, and the first circuit board 150 abuts against the surface of the first wire pressing member 170 facing away from the driving component 120; the first end 141 of the cable 140 is fixedly connected to the surface of the first circuit board 150 facing away from the first wire pressing member 170.
[0057] A mounting bracket 190 is fixedly connected to the lower end of the frame 110. The second circuit board 160 and the second wire pressing member 180 are fixedly connected to the mounting bracket 190. The second end 142 of the cable 140 is electrically connected to the second circuit board 160, and the second wire pressing member 180 fixedly connects the second end 142 of the cable 4 to the second circuit board 160. Specifically, the mounting bracket 190 is fixedly connected to the lower end of the frame 110 through its left and right ends. The second circuit board 160 is fixedly connected to the other surface of the mounting bracket 190 opposite to the first circuit board 150. The second end 142 of the cable 140 is connected to the second circuit board 160, and the second end 142 is fixed to the second circuit board 160 by the second wire pressing member 180.
[0058] The working principle of the linear motor 100 is that the driving component 120 and the mounting bracket 190 are supported by the frame 110 under force. The driving component 120 further supports the moving component 130, the first wire pressing member 170, and the first circuit board 150 under force. The mounting bracket 190 further supports the second wire pressing member 180 and the second circuit board 160 under force. The first circuit board 150 and the second circuit board 160 are electrically connected through the first end 141 and the second end 142 of the cable 140. When the second circuit board 160 is powered by an external power supply, the current flows through the second circuit board 160, the cable 140, and the first circuit board 150 in sequence, and finally reaches the driving component 120. After the driving component 120 is powered on, an electromagnetic effect is generated. Under the electromagnetic effect, the moving component 130 and the driving component 120 will perform relative reciprocating movements, and this reciprocating movement will cause the linear motor 100 to vibrate. When the linear motor 100 is working, due to the fixation of the first wire pressing member 170 and the second wire pressing member 180 on the first end 141 and the second end 142 of the cable 140, even if the driving component 120 and the moving component 130 vibrate, it will not affect the connection between the cable 140 and the first circuit board 150 and the second circuit board 160, reducing the possibility of the cable 140 becoming loose.

The first end 141 of the cable 140 is laid flat and electrically contacted and fixed with the lower plate surface of the first circuit board 150, and the first end 141 abuts against the wire pressing boss 172 on the side facing away from the first circuit board 150, so as to fix the first end 141 to the lower plate surface of the first circuit board 150 through the wire pressing boss 172. In this embodiment, after the first end 141 of the cable 140 is pre-fixed by the wire pressing boss 172, it is more convenient to lay the first end 141 of the cable 140 flat and electrically contact and fix it with the lower plate surface of the first circuit board 150. Moreover, the wire pressing boss 172 can play a certain fixing role on the first end 141 of the cable 140, making the electrical contact and fixation between the first end 141 of the cable 140 and the lower plate surface of the first circuit board 150 more stable and not easily falling off.

When the wire pressing boss 172 pre-fixes the first end 141 of the cable 140, the first end 141 of the cable 140 passes through the first wire pressing hole 173 on the wire pressing boss 172, and after the first end 141 of the cable 140 passes through the first wire pressing hole 173, it abuts against the inner wall surface of the first wire pressing hole 173. In this embodiment, by providing the first wire pressing hole 173 on the wire pressing boss 172, when the wire pressing boss 172 pre-fixes the first end 141 of the cable 140, the first end 141 is pre-fixed after passing through the first wire pressing hole 173. Therefore, it is convenient and fast to pre-fix the first end 141.
