Description

Technical Field

[0001] The utility model relates to the technical field of electronic products, and particularly relates to a key structure and an electronic product. Background Art

[0002] In modern electronic devices, the intuitiveness and interactivity of the user interface are crucial. As one of the basic components for users to interact with the device, the design of the key directly affects the user experience. To enhance this interaction experience, an indicator light is often designed at the center of the key to provide an intuitive feedback on the device status. The design of the indicator light can not only improve the aesthetic appearance of the device, but also provide necessary visual cues during device operation, such as low battery, signal status, or charging. However, when the indicator light is on, the light may scatter uncontrollably to other areas of the key, which is called "light leakage". Light leakage not only interferes with the user's visual experience, reduces the indication accuracy of the indicator light, but also may increase the power consumption of the device due to light scattering. In addition, the light leakage phenomenon may also cause visual interference to the user when the device is used at night or in a dimly lit environment. Summary of the Utility Model

[0039] The present utility model proposes a button structure 1000.

[0040] Please refer to Figures 1 to 5, in an embodiment of the present utility model, the button structure 1000 includes a base 1, a circuit board 4, a light-shielding member 5, and a pressing assembly; the base 1 has a receiving groove 101; the circuit board 4 is received in the receiving groove 101, and a point light source 41 and a switch 42 are arranged at intervals on the side of the circuit board 4 facing away from the base 1; the light-shielding member 5 is arranged on the circuit board 4, and the light-shielding member 5 is provided with a light-shielding hole, and the point light source 41 is located in the light-shielding hole; the pressing assembly is arranged on the side of the circuit board 4 facing away from the base 1, and the pressing assembly is used to trigger the switch 42, and the switch is provided with a light guide structure, and the light guide structure is arranged corresponding to the light-shielding hole.

[0041] There are various choices for the circuit board 4, such as single-layer PCB or double-layer PCB, etc. In this embodiment, the circuit board 4 is selected as FPC (flexible printed circuit board), which is composed of a flexible insulating substrate and conductive copper foil, and is suitable for scenarios with limited space or the need for bending.

[0042] There are also various choices for the point light source 41. In this embodiment, an LED (light-emitting diode) is selected, which has low power consumption and is relatively durable. In other embodiments, the point light source 41 can be selected as FLC (flexible light-emitting diode) or other light-emitting components according to requirements.

[0043] The light-shielding member 5 is made of light-impermeable materials such as silica gel and rubber, and has good elasticity and softness.

[0044] In the technical solution of the present utility model, by arranging the light-shielding member 5 on the circuit board 4 and opening the light-shielding hole, the light of the point light source 41 can only be transmitted through the light-shielding hole, and is not easily scattered to other areas, effectively controlling the divergence direction of the light. At the same time, in cooperation with the light guide structure, the light propagation path is further optimized, so that the light of the point light source 41 can be transmitted to the predetermined position, improving the user's visual experience.

[0045] Further, in an embodiment of the present utility model, please refer to Figure 4 , the button structure 1000 includes multiple groups of point light sources 41, and the multiple groups of point light sources 41 are arranged at intervals on the circuit board 4; the light-shielding member 5 is formed with multiple light-shielding holes, and each group of point light sources 41 is located in a light-shielding hole. The arrangement of multiple groups of point light sources 41 can provide a larger illumination area and better visual effects. At the same time, the multiple light-shielding holes can effectively control the divergence direction of the light of the multiple groups of point light sources 41, ensuring the user's visual experience. When pressing the switch 42, the multiple groups of point light sources 41 can emit light simultaneously or sequentially, and the specific light-emitting mode can be selected according to requirements. For example, in a product with gears, one or more groups of point light sources 41 can emit light corresponding to different gears. In addition, taking the LED as an example, each group of point light sources 41 can include one or more LEDs, and the specific number is selected according to the required luminous brightness to meet different usage scenarios.

[0046] It can be understood that, in order to enhance the user experience, the point light source 41 is usually arranged close to the center of the key structure 1000 to provide an intuitive feedback on the device status. Although this design is visually appealing, due to the presence of the point light source 41, the switch 42 cannot be placed exactly at the center of the key structure 1000. When the switch 42 deviates from the center position, the user may not be able to effectively trigger the switch 42 when pressing the key, thus affecting the reliability of the use of the key structure 1000. Therefore, in an embodiment of the present utility model, please refer to Figure 1 、 Figure 2 and Figure 5 , the pressing assembly includes a main key 3 and a pressing member 2; the pressing member 2 includes a pressing portion 21 and a support arm 22. The pressing portion 21 covers the notch of the receiving groove 101. The pressing portion 21 is formed with a light passing hole 2101, and the light passing hole 2101 is arranged corresponding to the point light source 41. The support arm 22 is arranged on the pressing portion 21; the main key 3 is arranged on the side of the pressing portion 21 away from the base 1. A light guiding portion 31 is provided in the middle of the main key 3, and the light guiding portion 31 is arranged corresponding to the light passing hole 2101; the light guiding structure includes the light passing hole 2101 and the light guiding portion 31; the key structure 1000 has a pressing state. In the pressing state, the support arm 22 abuts against and is limited by the base 1, and one end of the pressing portion 21 away from the support arm 22 presses the switch 42. When pressing the main key 3, since the support arm 22 abuts against and is limited by the base 1, one end of the pressing portion 21 away from the support arm 22 serves as a movable end. The movable end of the pressing portion 21 is not limited by the base 1, and its downward pressing amplitude when being pressed will be greater, so it has a greater downward pressing stroke and can more accurately and effectively trigger the switch 42, improving the reliability of the key structure 1000. Among them, the light passing hole 2101 of the pressing portion 21 allows light to pass through. Combined with the light guiding portion 31 of the main key 3, the light emitted by the point light source 41 can pass through the light passing hole 2101 and the light guiding portion 31 to be prominently expressed, so that the key structure 1000 simultaneously takes into account the function of obtaining the device status information. Among them, the light guiding portion 31 of the main key 3 is a light guiding column. The light guiding column can effectively guide the light emitted from a light source (such as an LED) to the area that needs illumination or display to improve the uniformity and utilization rate of the light. The light passing hole 2101 and the light guiding portion 31 do not need to be completely aligned, as long as the light emitted by the point light source 41 can be transmitted to the light guiding portion 31 through the light passing hole 2101.

[0047] Furthermore, in an embodiment of the present utility model, please refer to Figure 1 、 Figure 2 and Figure 5, the base 1 is formed with a groove 102 communicating with the accommodation groove 101, and the support arm 22 is accommodated in the groove 102; in the pressed state, the support arm 22 abuts against the bottom wall of the groove 102 for limiting. The design of the groove 102 can accommodate the support arm 22, so that at least part of the structure of the pressing part 21 can enter the accommodation groove 101, thus effectively reducing the overall thickness of the key structure 1000. In an actual product, the overall thickness of the key structure 1000 can be within 3.3 mm. In addition, the groove 102 can also limit the support arm 22 to ensure that the support arm 22 does not shift during the pressing process, and the position of the groove 102 can also be used as a reference during the installation process of the pressing member 2, which is convenient for assembly.

[0048] It can be understood that since the movable end of the pressing part 21 is located on one side of the pressing part 21, when the user presses, there will only be a feel on one side of the movable end, and the feel on the other side is poor. Therefore, in an embodiment of the present invention, please refer to Figure 2 , the pressing member 2 further includes an elastic arm 23, and the elastic arm 23 is arranged on the side of the pressing part 21 away from the support arm 22; in the pressed state, the elastic arm 23 abuts against the base 1 for limiting. The elastic arm 23 is located on the side of the pressing part 21 away from the support arm 22, and can provide additional support and elastic feedback during pressing. That is, in the pressed state, through the abutting and limiting action of the elastic arm 23 and the base 1, combined with the abutting and limiting action of the support arm 22 and the base 1, the stability and consistency of the pressing action are ensured. In this way, no matter from which angle the user presses, a similar feedback feel can be obtained, thereby improving the user experience. And the design of the elastic arm 23 can also prevent the support arm 22 from shifting during the pressing process, improving the stability of the key structure 1000.

[0049] Furthermore, in an embodiment of the present invention, please refer to Figure 2 , the base 1 is further formed with a storage groove 104, and a support portion 231 is provided at one end of the elastic arm 23 away from the pressing part 21. The bottom end of the support portion 231 contacts the bottom wall of the storage groove 104, that is, the elastic arm 23 contacts the base 1 through the support portion 231. In this way, during pressing, the elastic arm 23 will directly undergo elastic deformation, making the whole pressing process feel better and improving the user experience. Among them, a limiting post 11 is further provided on the bottom wall of the storage groove 104, and the support portion 231 is located between a side wall of the storage groove 104 and the limiting post 11. The setting of the limiting post 11 can limit the position of the support portion 231. In this way, after long-term use, the support portion 231 can also maintain contact with the bottom wall of the storage groove 104 to ensure the pressing feel.

[0050] It can be understood that after long-term use, the pressing member 2 may be deformed to produce an upward warping phenomenon. Therefore, in an embodiment of the present invention, please refer to Figure 2 and Figure 5, the base 1 is formed with a through hole 103; the pressing member 2 further includes a clamping portion 24, the clamping portion 24 is provided on the pressing portion 21, the clamping portion 24 and the support arm 22 are arranged at intervals, the clamping portion 24 passes through the through hole 103, and a clamping protrusion 241 is formed at a position of the clamping portion 24 away from the pressing portion 21. The clamping protrusion 241 can abut against and limit the side of the base 1 away from the pressing portion 21. Through the design of the clamping protrusion 241, the clamping protrusion 241 is located at one end of the clamping portion 24 away from the pressing portion 21, and the clamping protrusion 241 can abut against the side of the base 1 away from the pressing portion 21. When the clamping protrusion 241 abuts against the base 1, the movement of the pressing member 2 in the vertical direction can be restricted, thereby preventing the pressing member 2 from warping upwards. The clamping protrusion 241 is equivalent to a physical limit to ensure that the pressing member 2 remains within a predetermined position range during use. Among them, for the convenience of installation, the clamping protrusion 241 is provided on the side of the clamping portion 24 away from the pressing portion 21.

[0051] In order to further improve the reliability of the key structure 1000, in an embodiment of the present invention, please refer to Figure 3 , a relief groove 2102 is formed on the surface of the pressing portion 21 facing the circuit board 4, and a pressing protrusion 211 is provided at the bottom of the relief groove 2102; in the pressing state, the pressing protrusion 211 presses to trigger the switch 42. That is, during the pressing process, it is the pressing protrusion 211 that directly contacts and triggers the switch 42. In this way, compared with the direct contact between the pressing portion 21 and the switch 42, the contact area is smaller and the triggering is more stable, further improving the reliability of the key structure 1000; the pressing protrusion 211 can be directly provided on the pressing portion 21, but by providing the relief groove 2102 and then setting the pressing protrusion 211 at the bottom of the relief groove 2102, there are more choices when setting the protrusion height of the pressing protrusion 211. When the protrusion height is small, a greater force is required to trigger the switch 42, and the corresponding pressing stroke is deeper, which can give the user a more obvious pressing feedback. When the protrusion height is large, the switch 42 can be triggered more easily, improving the sensitivity of the key.

[0052] Furthermore, in an embodiment of the present invention, please refer to Figure 3, the pressing member 2 further includes two limiting protrusions 212. The two limiting protrusions 212 are provided on the side of the pressing portion 21 facing the circuit board 4. The two limiting protrusions 212 are located on the side of the light passing hole 2101 away from the support arm 22 and are respectively located on both sides of the pressing protrusion 211. Among them, the protruding height of the limiting protrusion 212 is greater than the protruding height of the pressing protrusion 211. In this way, during the pressing process, it is the support arm 22 that first abuts against and limits the base 1, and then the two limiting protrusions 212 abut against and limit the circuit board 4. Under the action of the support arm 22 and the two limiting protrusions 212, only the part of the pressing portion 21 provided with the pressing protrusion 211 will continue to press down, so that the pressing protrusion 211 contacts and triggers the switch 42, and the triggering is more stable, further improving the reliability of the key structure 1000. In addition, when the limiting protrusion 212 abuts against and limits the circuit board 4, the user will feel a definite stop point, which can provide better tactile feedback, and the limiting protrusion 212 can also prevent the pressing protrusion 211 from triggering the switch 42 when it is not fully pressed, reducing the possibility of mis-triggering.

[0053] Specifically, in an embodiment of the present invention, please refer to Figure 1 and Figure 5 , the pressing assembly further includes a silica gel layer 6. The silica gel layer 6 is provided on the side of the pressing member 2 away from the base 1. A receiving groove 601 is formed on the side of the silica gel layer 6 away from the pressing member 2. The main button 3 is received in the receiving groove 601. A light-transmitting portion 61 is provided on the bottom wall of the receiving groove 601, and the light-transmitting portion 61 is arranged corresponding to the light guide portion 31. The silica gel layer 6 can prevent the main button 3 from directly contacting the pressing member 2. Since the silica gel layer 6 itself has good elasticity and softness, it can provide good tactile feeling and buffering effect, improving the user's pressing experience. The design of the receiving groove 601 also facilitates the stability and accuracy of the installation of the main button 3. Among them, the light-transmitting portion 61 is arranged corresponding to the light guide portion 31, and this corresponding relationship can ensure that the light is effectively transmitted from the light guide portion 31 to the surface of the main button 3, providing uniform illumination. In addition, the silica gel material usually has good sealing performance, which can improve the waterproof and dustproof capabilities of the key structure 1000.

[0054] Furthermore, in an embodiment of the present invention, please refer to Figure 1 and Figure 5 , the pressing assembly further includes a cover plate 7. The cover plate 7 is covered on the base 1. The cover plate 7 is formed with a through hole, and the main button 3 is embedded in the through hole. The cover plate 7 can protect the internal components of the key structure 1000, prevent dust, moisture or other impurities from entering, and extend the service life. The cover plate 7 can also provide a smooth surface for the user to press, and can also enhance the overall aesthetics of the key structure 1000.

The specific structure of the key structure 1000 refers to the above-mentioned embodiments. Since this electronic product adopts all the technical solutions of the above-mentioned embodiments, it has at least all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be elaborated here one by one.
