Description

Technical Field

[0001] This disclosure pertains to the field of pressure sensing technology, specifically relating to an electronic device. Background Technology

[0002] Currently, there are two main types of mature virtual buttons: capacitive buttons and pressure-sensitive buttons. Capacitive buttons can detect large areas of touch, but capacitive touch triggers instantaneous activation, leading to accidental touches and making pressure detection impossible. Pressure-sensitive buttons can detect the degree of pressure applied, providing different functions based on the pressure applied, but conventional solutions only allow for single-point touch, resulting in a very small detection range. In some applications, electronic devices require pressure touch detection over large angles or even 360 degrees, which conventional capacitive and pressure-sensitive solutions cannot achieve.

[0003] To address the aforementioned problems, it is necessary to propose a reasonably designed electronic device that can effectively improve these issues. Utility Model Content

[0004] The embodiments disclosed herein are intended to at least address one of the technical problems existing in the prior art, and to provide an electronic device.

Detailed Implementation

[0017] To enable those skilled in the art to better understand the technical solutions of the embodiments of this disclosure, the embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0018] like Figures 1 to 4As shown, this embodiment of the disclosure provides an electronic device 100, which includes an internal structural component A and a plurality of pressure detection structures B spaced apart from the internal structural component. The plurality of spaced pressure detection structures B can realize the pressure detection function of the electronic device at large angles or 360 degrees.

[0019] The pressure detection structure B includes a pressing panel 110, a top pressing component 120, and a pressure sensor 130.

[0020] The pressing panel 110 is supported and fixed to the internal structural member A, so that a receiving chamber 140 is formed between the pressing panel 110 and the internal structural member A.

[0021] The pressure sensor 130 is located in the receiving chamber 140 and is disposed in the internal structural component A.

[0022] The internal structural component A has a hollow area 150 at the location corresponding to the pressure sensor 130. The hollow area 150 provides deformation space for the pressure sensor 130.

[0023] The first end of the pressure member 120 is fixed to the pressure sensor 130, and the second end of the pressure member 120 is in pressure contact with the pressing panel 110.

[0024] The electronic device of this disclosure includes an internal structural component and a plurality of pressure detection structures spaced apart on the internal structural component. Each pressure detection structure includes a pressing panel, a pressing member, and a pressure sensor. The pressing panel is supported and fixed to the internal structural component, forming a receiving chamber between the pressing panel and the internal structural component. The pressure sensor is located in the receiving chamber and disposed on the internal structural component. The internal structural component has a hollow area corresponding to the pressure sensor. A first end of the pressing member is fixed to the pressure sensor, and a second end of the pressing member makes pressing contact with the pressing panel. When the pressing panel is pressed down, the pressing member compresses and deforms, pressing against the pressure sensor, causing the pressure sensor to deform and thus detect the pressure signal. The electronic device of this disclosure, by having a plurality of pressure detection structures spaced apart on the internal structural component, can achieve a large-angle or 360-degree pressure detection function.

[0025] For example, multiple pressure detection structures B can be evenly distributed on the internal structural component A, which can better realize the large-angle or 360-degree pressure detection function of electronic devices.

[0026] like Figure 1 As shown, in one embodiment, to achieve 360-degree pressure detection in the circular internal structure A of the electronic device 100, three pressure detection structures B can be set along the arc edge respectively. Through software algorithm processing, pressure detection can be achieved when pressing in the entire circular area.

[0027] like Figure 3 As shown, in another embodiment, in the circular internal structure A of the electronic device 100, in order to realize the 360-degree pressure detection function, two pressure detection structures can be set along the arc edge respectively. Through software algorithm processing, the pressure detection function can be realized when pressing in the entire circular area.

[0028] It should be noted that in this embodiment, the number of pressure detection structures B is not specifically limited and can be selected according to actual needs, as long as the large-angle pressure detection function of the electronic device can be realized.

[0029] For example, preferably, in this embodiment, the hollow area 150 corresponds to the central region of the pressure sensor 130. The pressure member 120 is disposed in the sensing area of ​​the central region of the pressure sensor 130. The pressure member 120 is located in the maximum deformation area of ​​the pressure sensor 130, and the hollow area 150 provides the maximum deformation space for the deformation of the pressure sensor 130, thereby increasing the detection sensitivity of the pressure sensor 130.

[0030] For example, in this embodiment, the pressure member 120 can be bonded and fixed to the central region of the pressure sensor 130. It should be noted that the pressure member 120 can also be fixed to the pressure sensor 130 by means of snap-fit ​​or interference fit. This embodiment does not specifically limit the fixing method of the pressure member 120; it can be selected according to actual needs.

[0031] For example, in one embodiment, the pressing panel 110 can be supported and fixed to the internal structural member A by processes such as overmolding.

[0032] For example, in another embodiment, the pressure detection structure B further includes a support member 160; the pressing panel 110 is supported and fixed to the internal structural member A by the support member 160. Specifically, both ends of the support member 160 can be fixed to the pressing panel 110 and the internal structural member A respectively by adhesive. By providing the support member 160, a larger receiving chamber 140 can be provided, facilitating the installation of the pressure sensor 130.

[0033] For example, the internal structural member A is provided with a boss, and the pressing panel 110 is supported and fixed to the boss. Specifically, the pressing panel 110 can be supported and fixed to the boss by an adhesive or a support member 160. In this embodiment, supporting and fixing the pressing panel 110 to the boss can provide a larger receiving chamber 140.

[0034] For example, the pressure sensor 130 may include a piezoresistive pressure sensor, a piezoelectric sensor, or a strain gauge pressure sensor. The piezoresistive pressure sensor may have a single-bridge, half-bridge, or full-bridge Wheatstone bridge structure. The specific type of pressure sensor 140 is not limited and can be selected according to actual needs.

[0035] For example, the pressure member 120 can be made of an elastic material, such as rubber. This embodiment does not specifically limit the material of the pressure member 120; it can be selected according to actual needs.

[0036] It should be noted that electronic devices can be cylindrical products such as smart pens and small polishing pens. At least two pressure detection structures can be set in their button area. With the help of pressure detection algorithms, the large-angle press detection function of the pressing panel can be realized, and the pressure detection function can reach up to 360 degrees.

[0037] It is understood that the above embodiments are merely exemplary implementations used to illustrate the principles of the embodiments of this disclosure, and the embodiments of this disclosure are not limited thereto. For those skilled in the art, various modifications and improvements can be made without departing from the spirit and essence of the embodiments of this disclosure, and these modifications and improvements are also considered to be within the protection scope of the embodiments of this disclosure.
