However, besides the digital camera of this embodiment, the electronic device 1 can also be an electronic device with a camera function such as a mobile phone or a PDA.

Next please refer to FIG. 2 and FIG. 2A , which illustrate the first embodiment of the switching mechanism of the present invention. The switching mechanism mainly includes the above-mentioned turntable 10 and the pressure sensing module 13, wherein the turntable 10 includes a turntable body 101, a shaft portion 103 connecting the turntable body 101 and the electronic device 1, and is arranged at the bottom of the turntable body 101 and has a ring-shaped bottom surface. Beveled contact portion 102 . The pressure sensing module 13 is electrically fixed to the electronic device 1 and located below the turntable 10 . The pressure sensing module 13 includes a button portion 133 b that can move up and down, and keeps in contact with the bottom surface of the contact portion 102 . When the turntable 10 rotates, the contact part 102 can press the button part 133b of the pressure sensing module 13, and the pressure sensing module 13 can output different signals according to the movement amount of the button part 133b. Because the bottom surface of the contact portion 102 has an annular slope, when the plane of the contact portion 102 of the contact button portion 133b was higher, the button portion 133b was pressed down less (as shown in Figure 2); When the plane of the part 102 is lower, the push button part 133b is pushed down a greater distance (as shown in FIG. 2A ).

Please refer to FIG. 3 and FIG. 4 , the above-mentioned pressure sensing module 13 includes an accommodating housing 130 whose outer top surface is close to the bottom surface of the contact portion 102 and is provided with an opening 131 . In addition, the accommodating housing 130 is opposite to A shaft frame 132 is recessed on both sides respectively.

The pressure sensing module 13 also includes an actuator 133, which includes a plate 133a, and one side thereof is provided with a shaft 133d, so as to be movably assembled on the shaft frame 132 of the housing 130 in a shaft connection. superior. The aforementioned button portion 133 b is formed on the top surface of the sheet body 133 a , and passes through the opening 131 so as to abut against the bottom surface of the contact portion 102 . In addition, in this embodiment, the actuator 133 is provided with a communication groove 133c on three sides of the sheet body 133a.

The pressure sensing module 13 also includes an elastic conductive member 134, which includes a sleeve portion 134a that is sleeved in the communication groove 133c of the actuator 133, and is bent by the sleeve portion 134a and the end abuts against the receiving portion. An elastic recovery portion 134b is disposed on the inner bottom surface of the casing 130 .

The pressure sensing module 13 also includes a resistance unit 135 connected to one side of the containing case 130, which includes a metal plate body 1351 obliquely attached to the inside of the containing case 130, and the metal plate body One end of 1351 is bent integrally and passes through a guide pin 1352 of the housing 130 . The metal plate body 1351 is in contact with the sleeve portion 134a of the elastic conductive member 134. When the button portion 133b is pressed and the sheet body 133a is lowered, the contact position between the sleeve portion 134a and the metal plate body 1351 can be changed. , to generate a corresponding resistance value, the inclined metal plate body 1351 can increase the extension length to increase the moving distance that can be in contact with the elastic conductive member 134, so as to reduce the error of the measured resistance value. The pin 1352 is connected to the interior of the electronic device 1 for power supply.

The pressure sensing module 13 also includes a conduction unit 136 connected to the other side of the housing 130 opposite to the resistance unit 135 , which includes a metal plate vertically attached to the inside of the housing 130 136a, and another guide pin 136b that is integrally bent from one end of the metal plate body 136a and passes through the housing 130, wherein the metal plate body 136a is also used to contact the sleeve portion 134a of the elastic conductive member 134 , and the pin 136b is electrically connected to the inside of the electronic device 1 , and cooperates with the pin 1352 of the resistance unit 135 to form a path for outputting a resistance signal to the electronic device 1 .

Please refer to FIG. 5 , which is a schematic diagram of the pressure sensing module 13 when the button portion 133 b is pressed for a small distance. When the button part 133b is pressed for a small distance, that is, when the button part 133b contacts the contact part 102 of the aforementioned turntable 10, the plane is relatively high, and the sleeve part 134a of the elastic conductive member 134 is in contact with the metal plate body 1351 of the resistance unit 135. In the upper position, the length of the electronic signal flowing through the metal plate body 1351 is longer, so a larger resistance value can be generated.

Please refer to FIG. 6 , which is a schematic diagram showing that the pressure sensing module 13 is pushed farther away from the button portion 133b. When the push button part 133b is pressed for a large distance, that is, when the plane of the button part 133b contacting the contact part 102 of the aforementioned turntable 10 is low, the sleeve part 134a of the elastic conductive member 134 can be made to contact the metal plate of the resistance unit 135 The body 1351 is lower than the position, and the length of the electronic signal flowing through the metal plate body 1351 is shorter, so a smaller resistance value can be generated.

Therefore, as long as the numerical difference of the resistance value between the larger amplitude and the smaller amplitude of the pressed button portion 133b of the pressure sensing module 13 is obtained, and then segmented in a numerical manner, the function switching of the turntable 10 can be set. the number of segments. For example, if the resistance value when the button part 133b is pressed down is defined as 100, and the smaller range is defined as 0, if the value in between is divided into 10 parts, and the function of switching between 10 stages can be generated, The number of numerical divisions can be defined according to actual needs.

In addition, a step mechanism (not shown) may be provided between the shaft portion 103 of the turntable 10 and the electronic device 1 , the purpose of which is to allow the user to confirm the switching of the function through the step feeling generated when the turntable 10 is rotated.

Next, please refer to FIG. 7 and FIG. 7A , which are schematic diagrams of a second embodiment of the switching mechanism of the present invention. The switching mechanism of this embodiment includes a resistance unit 135a and a turntable 10a. Wherein, the turntable 10a includes a contact portion 102a, and the resistance unit 135a is in contact with the contact portion 102a. When the turntable 10a rotates, the contact portion 102a can move in a circular arc trajectory. In this embodiment, the contact part 102a is a conductive piece, and a contact point 102b electrically connected to the electronic device 1 is provided at the end thereof for signal transmission. The resistor unit 135a is a C-shaped metal piece, and one end of the C-shaped metal piece has a contact 135b electrically connected to the electronic device 1 for signal transmission.

When the turntable 10a is at the position shown in FIG. 7 , the length of the electronic signal flowing through the resistance unit 135a (from the contact point 135b to the contact point 102b ) is longer, so a larger resistance value can be generated.

When the turntable 10a rotates counterclockwise from the position shown in FIG. 7 , the contact position between the contact portion 102a and the resistance unit 135a can be changed. When the turntable 10a is rotated at the position shown in 7A, the length of the electrical signal flowing through the resistance unit 60a (from the contact point 135b to the contact point 102b) is shorter, so a smaller resistance value can be generated.

Therefore, as long as the numerical relationship between the rotation of the turntable 10a to different positions and the resulting resistance value is obtained, the number of segments for function switching of the turntable 10a can be set.

Compared with the complex structure in the prior art that requires a plurality of circuit contacts in the circuit board of the electronic device to achieve the function switching of the turntable, the switching mechanism of the present invention and the electronic device with the switching mechanism utilize a pressure sensing module to cooperate The simple structure of the inclined surface on the bottom surface of the turntable can achieve the purpose of having multiple switchable functions, and its overall structure is relatively simple compared with the prior art.

Also, because the prior art must be provided with a plurality of circuit contacts on the circuit board, plus the complicated process that must be provided with the conductive sheet linked to the turntable, the switching mechanism of the present invention and the electronic device with the switching mechanism only need to The pressure sensing module is fixedly connected to the electronic device and its two leads are electrically connected to the electronic device, and then the turntable is pivotally connected to the electronic device to cover the pressure sensing module. The required process is very simple.

Moreover, compared with the situation in the prior art that the conductive sheet cannot accurately touch the contacts on the circuit board when the electronic device is switching functions, which leads to failure, the switching mechanism of the present invention and the electronic device with the switching mechanism are The size of the output resistance value is determined by the difference in the position of the elastic conductive part in the pressure sensing module contacting the metal sheet of the resistance unit, and the switching of the function is determined according to the size of the resistance value, which greatly reduces the misplacement concerns of the prior art. Operational failure rate.

To sum up, the present invention shows its characteristics different from the prior art in terms of purpose, means and effect. However, it should be noted that the above-mentioned embodiments are only illustrative to illustrate the principles and effects of the present invention, and are not intended to limit the scope of the present invention.
