[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] Example 1

[0029] An embodiment of the present invention provides a sliding button assembly 100, which, as shown in Figures 1 to 3, includes a support frame 1, a circuit board 2 fixed to one side of the support frame 1, a sensor module 3 fixed to the side of the circuit board 2 away from the support frame 1, and a button 4 fixed to the side of the sensor module 3 away from the circuit board 2; the sensor module 3 includes multiple groups of sensor components arranged in sequence and spaced apart from each other; each group of sensor components includes multiple capacitive sensors 31 arranged in sequence and spaced apart from each other, and the capacitive sensors 31 are electrically connected to the circuit board 2.

[0030] The number of sensor assemblies and the number of capacitive sensors 31 in each sensor assembly group are set according to actual needs and are not specifically limited here. The multiple capacitive sensors 31 in each sensor assembly group can also be called a segment of capacitive sensors 31.

[0031] Specifically, the support frame 1 includes a base plate 11, two support plates 12 respectively fixed at the two ends of the base plate 11, a middle plate 13 whose two ends are respectively fixed to the two support plates 12 on the side away from the base plate 11, and a top plate 14 arranged on the side of the middle plate 13 away from the support plates 12 and spaced from the middle plate 13; the two ends of the top plate 14 are respectively fixed to the two ends of the middle plate 13 by two elastic members 15, and the circuit board 2 is fixed to the side of the top plate 14 away from the middle plate 13.

[0032] Each support plate 12 includes a first sub-support plate 121 fixed to the bottom plate 11 and a second sub-support plate 122 extending from the first sub-support plate 121 toward the other support plate 12 ; the end of the middle plate 13 is fixed to the second sub-support plate 122 .

[0033] The base plate 11 is provided with two first mounting holes 111 extending therethrough. The two first sub-support plates 121 are provided with second mounting holes 1211 extending therethrough at positions corresponding to the first mounting holes 111. The two second mounting holes 1211 are connected to the two first mounting holes 111. This design allows the sliding button assembly 100 to be more easily mounted on the housing of an electronic device via the second mounting holes 1211 and the first mounting holes 111.

[0034] The middle plate 13 includes a middle plate 131 and two end plates 132 respectively fixed at both ends of the middle plate 131; the middle plate 131 is spaced apart from the bottom plate 11, and the two end plates 132 are respectively fixed to the side of the two second sub-support plates 122 away from the bottom plate 11.

[0035] The two elastic members 15 are respectively fixed to the side of the two end plates 132 away from the second sub-support plate 122, and the elastic members 15 are made of foam. Of course, according to actual needs, the elastic members 15 can also be made of springs or elastic rubber.

[0036] Specifically, the multiple sensor assemblies are arranged at equal intervals, and the multiple capacitive sensors 31 are arranged at equal intervals. This design can better enhance the positioning and sensitivity of the sliding button assembly 100 during progressive adjustment control. Of course, depending on actual needs, the multiple sensor assemblies can be arranged at unequal intervals, and the corresponding multiple capacitive sensors 31 can also be arranged at unequal intervals, but the effect will be less than that of an equidistant arrangement.

[0037] In this embodiment, both ends of the button 4 are respectively provided with extension portions 41 that protrude toward the circuit board 2 and abut against the circuit board 2 .

[0038] The sliding button assembly 100 in this embodiment adopts a sensor module 3 to replace the mechanical structure button 4 of the related technology, and limits the sensor module 3 to include multiple groups of sensor components arranged in sequence and spaced apart from each other, and limits each group of sensor components to include multiple capacitive sensors 31 arranged in sequence and spaced apart from each other. In this way, when it is necessary to implement progressive adjustment of the button 4 control, the action of a certain group of sensor components will cause partial action of the capacitive sensors 31 in other adjacent sensor components, and then the center position calculation method of the interpolation algorithm is used to make the touch position resolution greater than the number of slider segments, so as to locate the position of the finger press, and track the position change to identify the sliding gesture and degree, so as to improve the sensitivity.

[0039] Example 2

[0040] An embodiment of the present invention provides an electronic device 200, as shown in Figures 1 to 5, which includes a housing 201 and the sliding button assembly 100 in the above-mentioned embodiment 1; the side of the housing 201 is provided with a through hole 202 passing through it, and the support frame 1 is fixed to the housing 201 so that the button 4 passes through the through hole 202 and is exposed outside the housing 201.

[0041] The electronic device 200 is a mobile phone, a watch, a tablet computer, etc.

[0042] Since the electronic device 200 in this embodiment includes the sliding button assembly 100 in the above-mentioned embodiment 1, it can also achieve the technical effects achieved by the sliding button assembly 100 in the above-mentioned embodiment 1, which will not be described in detail here.
