Referring to fig. 1-3, an embodiment of the present invention provides a pressure-sensitive key structure, which includes a housing 110, an auxiliary circuit board 120, a pressure-sensitive chip 130, and a main circuit board 140. The housing 110 has a deformable pressing portion 112, the sub circuit board 120 is accommodated in the housing 110 and abuts against the pressing portion 112, the pressure sensing chip 130 is disposed on the sub circuit board 120 and is used for sensing the pressure applied to the sub circuit board 120, and the main circuit board 140 is electrically connected to the sub circuit board 120. When the pressing portion 112 is pressed, the pressing portion 112 deforms and applies pressure to the sub circuit board 120, so that the pressure sensing chip 130 senses the pressure and controls the on/off of the main circuit board 140 through the sub circuit board 120.
According to the pressure-sensitive key structure provided by the above embodiment, after a user applies a certain acting force to the pressing portion 112, the pressing portion 112 deforms slightly, and applies a slight acting force to the secondary circuit board 120 abutting against the pressing portion, the pressure-sensitive chip 130 generates a slight current change after receiving the acting force, amplifies the current through the secondary circuit board 120, and sends the amplified current to the main circuit board 140, and the main circuit board 140 receives the current and controls the on-off of the circuit.
With the pressure-sensitive key structure, the on-off of the main circuit board 140 is controlled by the deformation of the pressing part 112 on the shell 110. Compared with the existing travel switch key, the pressing part 112 and the shell 110 are of an integrated structure, so that the problem of key clamping caused by dirt is solved.
Referring to fig. 1, in an embodiment of the present invention, the pressing portion 112 has a texture or structure for indicating the position of the pressing portion 112.
It is understood that the texture may be a pattern with a key mark, a text, or a structure for distinguishing the peripheral features of the key mark. By adopting the design, the use of the product is convenient for users, and the humanization degree of the product is improved.
Referring to fig. 1 and fig. 2 or fig. 3, in a specific embodiment, the pressing portion 112 is provided with a groove 1122 for a user to press, and the groove 1122 is opposite to the pressure-sensitive chip 130.
It should be noted that, by adopting the design of the groove 1122, not only the position of the pressing portion 112 can be indicated, but also the wall thickness of the pressing portion is relatively reduced, so that the structure of the pressing portion is deformed, and the effect of the pressure sensing chip 130 on/off control of the main circuit board 140 is enhanced. Moreover, the concave groove 1122 is opposite to the pressure-sensitive chip 130, so that the sensing capability of the pressure-sensitive chip 130 to the acting force applied from the pressing part 112 can be improved, and the control effect of the pressure-sensitive chip 130 to the main circuit board 140 can be further improved.
In a more specific embodiment, the groove 1122 is a circular groove 1122, and a transition arc is provided at the connection of the groove 1122 and the housing 110. By adopting the design of the transition arc, on one hand, the hand feeling of the user contacting the groove 1122 can be improved, on the other hand, the connection between the groove 1122 and the shell 110 can be smoother, the stress concentration can be prevented, the structural strength of the pressing part 112 can be improved, and on the other hand, the deformation of the pressing part 112 can be facilitated.
Based on any of the above embodiments, the present invention provides another embodiment, in which the deformation amount of the pressing portion 112 is less than or equal to 0.1 mm.
Based on any of the above embodiments, the present invention provides another embodiment, in which the end surface of the sub circuit board 120 abutted against the pressing portion 112 is a plane. It should be added that the pressing portion 112 may be a plane or a cambered surface on the outer side of the housing 110. By adopting the design, the transmission effect of the pressing part 112 and the secondary circuit board 120 can be improved, and compared with the cambered surface, the secondary circuit board 120 is not easy to separate from the pressing part 112.
In an embodiment, a pasting member is disposed between the sub-circuit board 120 and the pressing portion 112, and two sides of the pasting member are respectively fixedly connected to the sub-circuit board 120 and the pressing portion 112.
Preferably, the sticker is a double-sided tape.
Optionally, the sticker is an adhesive.
The sub-circuit board 120 is fixed on the pressing portion 112 by the sticking piece, so that the assembly is simple, and the bonding effect is relatively strong.
Referring to fig. 3 and 4, based on any of the above embodiments, another embodiment of the present invention is provided, in which the main circuit board 140 and the sub circuit board 120 are electrically connected through a deformable elastic member 150. When the pressing portion 112 deforms and applies a force to the sub circuit board 120, the sub circuit board 120 also displaces, and the relative position between the sub circuit board 120 and the main circuit board 140 changes. The design of the elastic member 150 connecting the main circuit board 140 and the sub circuit board 120 can provide a certain limit for the displacement of the sub circuit board 120. Compared with rigid connection, the phenomenon of disconnection between the main circuit board 140 and the auxiliary circuit board 120 can be reduced.
In a specific embodiment, the elastic member 150 includes a first connection portion 152 connected to the main circuit board 140, a second connection portion 154 connected to the sub circuit board 120, and a third connection portion 156 connecting the first connection portion 152 and the second connection portion 154, and the third connection portion 156 is disposed in a U-shape. It can be understood that the U-shaped third connecting portion 156 has a certain deformation capability and a capability of resetting after deformation, and with this design, the structure is relatively simple, the production cost is relatively low, and the occupied space is small, thereby improving the compactness of the product structure.
Preferably, the elastic member 150 is made of copper and is formed by a sheet metal process.
With continued reference to fig. 4, in a more specific embodiment, an arc-shaped groove is formed at an end of the third connecting portion 156 connected to the first connecting portion 152, and the third connecting portion 156 is connected to the first connecting portion 152 through the arc-shaped groove; the second connecting portion 154 is disposed in a U-shape, and the sub circuit board 120 is connected to the bottom of the second connecting portion 154.
In this embodiment, the design of the arc-shaped groove in the third connecting portion 156 and the design of the U-shape of the second connecting portion 154 can further improve the deformation capability of the elastic member 150.
Referring to fig. 1 and 2, another embodiment of the present invention further provides an electric toothbrush, including the pressure button structure provided in any of the above embodiments.
The electric toothbrush structure also includes a brush head 200 for brushing teeth and a battery for providing energy. After the user presses the pressing portion 112, the main circuit board 140 is connected to control the operation of the brush head 200. When the user presses the pressing portion 112 again, the main circuit board 140 is disconnected to control the brush head 200 to stop working.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
