Description
Technical Field
[0001] The utility model relates to the technical field of electronic keys, and more specifically, to an electric dial button device. In addition, the utility model also relates to an electronic product comprising the electric dial button device. Background Art
[0002] As the requirements for the exterior decoration of electronic products continue to improve, the exposed moving parts in many products are processed by processes such as electroplating, PVD (Physical Vapor Deposition), and metal. Among them, the key device to achieve the touch function is the capacitive film. Due to space limitations and modeling reasons, there are cases where the conductive parts are close to the capacitive film. In the specific use process, the following problems exist:
[0003] 1. Since the electroplated dial button is close to the capacitor film, when the user touches the dial button, if the voltage of the static electricity reaches a large enough level, the static electricity will break through the air and reach the capacitor film, causing the capacitor film to be broken down; thus causing the touch function to fail.
[0004] 2. Since the conductive component is close to the capacitor film, the capacitance value of the capacitor film will be disturbed during actual use, and the capacitance value of the capacitor film will change due to the touch button.
[0005] In summary, how to provide a dial button device that can prevent the capacitor film from being broken down or reduce the interference of the capacitance value of the capacitor film by the adjacent conductive moving parts is a problem that needs to be solved urgently by those skilled in the art. Utility Model Content
[0006] In view of this, the purpose of the utility model is to provide an electric dial button device, which realizes grounding of the moving part through a grounding structure, thereby preventing the capacitance value of the capacitor film from changing significantly when the capacitor film is broken down or the electric dial button device is touched.

[0038] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0039] The core of the utility model is to provide an electric dial button device, which realizes grounding of the moving part through a grounding structure, thereby preventing the capacitance value of the capacitance film from changing significantly when the capacitance film is broken down or the electric dial button device is touched.
[0040] Another core of the utility model is to provide an electronic product including the electric dial button device.
[0041] Please refer to Figure 1 and Figure 2 .
[0042] This specific embodiment discloses an electric dial button device, including a moving part 1, a circuit board 2 and a grounding structure 3, wherein the moving part 1 is movably arranged; the circuit board 2 is provided with a grounding portion for grounding; the grounding structure 3 electrically connects the moving part 1 and the grounding portion of the circuit board 2 to ground the moving part 1.
[0043] It should be noted that, during the actual setting process, a capacitive film is generally set near the electric dial button device in this specific embodiment, and the corresponding control is achieved by changing the capacitance value during pressing the capacitive film. However, since the distance between the electric dial button device and the capacitive film is relatively close, static electricity may break through the capacitive film when the moving part 1 of the electric dial button device is pressed, or the capacitance value of the capacitive film may change significantly when the electric dial button device and the capacitive film are accidentally touched at the same time, thereby affecting the normal use of the product.
[0044] In this specific embodiment, the moving part 1 can be made of conductive material as a whole, or a conductive layer can be set on the surface of the moving part 1. The grounding structure 3 is a conductive structure. Specifically, the grounding structure 3 can be made of conductive material as a whole, or a conductive coating can be set on the surface of the grounding structure 3. The specific details are determined according to actual conditions and will not be elaborated here.
[0045] In this specific embodiment, a grounding structure 3 is provided. During actual use, when static electricity is generated by touching the dial button device, the static electricity generated on the moving part 1 will be transmitted to the grounding part of the circuit board 2 through the grounding structure 3, so that the moving part 1 is grounded, which can effectively prevent static electricity from breaking through the air and then breaking through the capacitor film that is relatively close. In addition, when the dial button device and the capacitor film that is relatively close are touched at the same time, the moving part 1 is grounded due to the provision of the grounding structure 3. At this time, the moving part 1 and the capacitor film are in contact with the operator at the same time, which is equivalent to realizing the grounding of the capacitor film, so that the capacitance value of the capacitor film is prevented from being affected by the conduction between the moving part 1 and the capacitor film through the operator. The capacitance value of the capacitor film changes little, which can effectively prevent accidental touches.
[0046] Based on the above embodiment, the moving part 1 can be set to swing, and the specific swing direction can be as follows: Figure 2 In the actual setting process, a contact portion 321 for contacting the moving part 1 can be set on the grounding structure 3, and the swing center axis of the moving part 1 coincides with the contact portion 321.
[0047] During actual use, when the moving part 1 swings, the central axis of the swing coincides with the contact portion 321, so that the contact position of the moving part 1 and the grounding structure 3 remains unchanged. The moving part 1 swings around the contact portion 321, and there is no relative friction between the moving part 1 and the grounding structure 3. The feel of the swinging operation of the moving part 1 can be kept unchanged, further improving the use experience, reducing the interference of the capacitance value of the capacitive film with the adjacent moving parts without affecting the normal operation feel of the moving part.
[0048] Specifically, the grounding structure 3 can include an elastic member 31 and a connecting member 32, wherein one end of the elastic member 31 is connected to the grounding portion; the connecting member 32 is arranged at the other end of the elastic member 31, and the connecting member 32 is provided with a contact portion 321; the contact portion 321 always keeps in contact with the moving member 1, and the elastic member 31 always keeps in contact with the grounding portion; the elastic member 31 and the connecting member 32 are both made of conductive materials.
[0049] Specifically, the elastic member 31 can be set as a spring, or as a spring sheet, or as other structures that meet the requirements. The specific structure is determined according to actual conditions and will not be elaborated here.
[0050] like Figure 1 As shown, the connecting member 32 can be set as a metal top pin 54, and the metal top pin 54 is covered on the outside of the elastic member 31 by one end of the elastic member 31 facing the moving member 1, and the metal top pin 54 is provided with a top arc surface. Specifically, the top arc surface can be set to a hemispherical shape, and the contact portion 321 is the center position of the outer surface of the hemispherical top arc surface.
[0051] Specifically, the metal ejector pin 54 may be made entirely of metal, or a metal conductive coating may be sprayed on only the outer surface of the metal ejector pin 54 , and the inner material of the metal ejector pin 54 is not limited.
[0052] The connector 32 may also be configured as a spherical metal structure. The spherical metal structure may be made entirely of metal, or a metal conductive coating may be sprayed on the outer surface of the spherical metal structure. The internal material of the spherical metal structure is not limited.
[0053] The spherical metal structure and the elastic member 31 may be configured as an integral structure, or the spherical metal structure and the elastic member 31 may be configured as a separate structure, which is determined according to actual conditions.
[0054] The setting of the elastic member 31 can keep the moving member 1 and the grounding part in a connected state at all times, and when the moving member 1 is pressed, the elastic force of the elastic member 31 reacts to the moving member 1, so that the operator has a certain pressing feeling, which can effectively improve the use experience.
[0055] like Figure 1 As shown, the moving part 1 is a shell 53 structure, and a first protrusion 11 is provided on the lower surface of the moving part 1. The first protrusion 11 is used to abut against the grounding structure 3, which can effectively reduce the mass of the moving part 1.
[0056] like Figure 2 As shown, it also includes a mounting body 5, the circuit board 2 is arranged in the mounting body 5, the mounting body 5 is provided with a guide groove 51, the elastic member 31 and the connecting member 32 are both arranged in the guide groove 51, and the end of the connecting member 32 extends out of the guide groove 51 and contacts with the moving member 1.
[0057] In actual use, when the elastic member 31 is extending and retracting, the guide groove 51 can play a certain guiding effect.
[0058] like Figure 1 As shown, the installation body 5 also includes a bracket 52 and a shell 53. During the movement of the moving part 1, the bracket 52 is used to support the moving part 1. At the same time, the bracket 52 is provided with a bracket shaft hole 521, and the shell 53 is provided with a shell rotating shaft 531. During the rotation of the moving part 1, the bracket 52 provides support for the moving part 1 and enables the moving part 1 to rotate smoothly.
[0059] In a specific embodiment, the electric dial button device further includes a switch pad 4, which is used to trigger the circuit board 2. During the movement of the moving part 1, the switch pad 4 is pressed to apply pressure to the circuit board 2. Figure 2 As shown, the mounting body 5 is provided with a push pin 54 . When the moving part 1 is pressed, the second protrusion 12 on the lower surface of the moving part 1 presses the switch pad 4 through the push pin 54 to transmit relevant information to the circuit board 2 .
[0060] Specifically, the switch pad 4 is an elastic structure. When the moving part 1 is pressed, the elastic part 31 and the switch pad 4 simultaneously apply a reaction force to the moving part 1. The feel value is designed in such a way that the feel of the switch pad 4 is superimposed on the feel of the elastic part 31 to meet the overall feel requirements.
[0061] In addition to the above-mentioned electric dial button device, the present invention also provides an electronic product including the electric dial button device disclosed in the above-mentioned embodiment and a capacitive film. For the structures of other parts of the electronic product, please refer to the prior art and will not be described in detail herein.
[0062] Specifically, when the spacing between the electric dial button device and the capacitor film meets the requirements, a retaining wall structure for blocking static electricity can be provided at the gap between the electric dial button device and the capacitor film to prevent static electricity from breaking through the capacitor film.
[0063] Each embodiment in this specification is described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the embodiments can be referenced to each other. Any combination of all embodiments provided by the utility model is within the protection scope of this utility model and will not be described in detail here.
