[0022] The utility model provides a button with a projection lamp.

[0023] See also Figures 1 to 3In one embodiment of the present invention, the button with projection light includes:

[0024] A first circuit board 30 , wherein a support portion 70 is provided on the first circuit board 30 ;

[0025] A pressing portion 20 , the pressing portion 20 being plugged into the supporting portion 70 and guiding light;

[0026] The light emitting portion 60 is disposed in the supporting portion 70 .

[0027] It can be understood that the pressing portion 20 guides light, and when the light-emitting portion 60 emits light, the light passes through the pressing portion 20 .

[0028] It should be noted that the light emitting portion 60 is a projection component, which is connected to the first circuit board 30 . When the pressing portion 20 is pressed, the light emitting portion 60 emits light through the pressing portion 20 to the outside and projects.

[0029] In one embodiment, the light emitting portion 60 is an LED lamp.

[0030] like Figure 1 and Figure 5 As shown, the support portion 70 is a structure for supporting the light-emitting portion 60 . To facilitate the operation of the light-emitting portion 60 , a plurality of pins are connected to the side of the support portion 70 , and the plurality of pins are plugged into the first circuit board 30 .

[0031] It can be understood that the support part 70 accommodates the light-emitting part 60 and the pressing part 20. When the pressing part 20 is pressed, it can synchronously trigger the light-emitting part 60 to emit light, so that light can be projected to the outside through the pressing part to prompt the user and enhance the user experience.

[0032] It is understandable that the light-emitting portion 60 and the pressing portion 20 are integrated into the supporting portion 70 so that the supporting portion 70 can be installed on the first circuit board 30 during installation, thereby improving component installation efficiency and reducing component processing costs.

[0033] In one embodiment, when the first circuit board 30 is powered on, the light-emitting portion 60 is always in a light-emitting state. When the light is projected onto the display placement surface through the pressing portion 20, it can prompt the user of the position of the pressing portion 20, making it easier for the user to quickly find the pressing portion 20.

[0034] The technical solution of the present invention is to integrate the pressing portion 20 and the light-emitting portion 60 into the supporting portion 70. When the pressing portion 20 is pressed, the light-emitting portion 60 is triggered to emit light synchronously. The light used as a prompt is projected to the outside through the pressing portion 20 that can guide light, so that the pressing portion 20 can emit light. When the user uses it, the position of the pressing portion 20 can be accurately found, thereby improving the user experience. Moreover, the pressing portion 20 and the light-emitting portion 60 are integrated into one, which reduces the area occupied by the first circuit board 30 and reduces the number of components, thereby reducing the component cost and component processing cost.

[0035] In one embodiment, the pressing portion 20 and the light emitting portion 60 are disposed opposite to each other.

[0036] like Figure 5 As shown, in order to facilitate more efficient projection of the light emitted by the light emitting portion 60 outward through the pressing portion 20 , the pressing portion 20 and the light emitting portion 60 are arranged on the same straight line.

[0037] It is understandable that the pressing portion 20 is arranged in the direction in which the light-emitting portion 60 is projected toward the first circuit board 30 , so that as much light as possible emitted by the light-emitting portion 60 can be projected to the outside through the pressing portion 20 , thereby improving the projection effect and quality.

[0038] In one embodiment, a trigger structure 40 is provided on the supporting portion 70 , the pressing portion 20 contacts the trigger structure 40 , and the trigger structure 40 is provided between the light emitting portion 60 and the pressing portion 20 .

[0039] like Figures 1 to 3 As shown, the trigger structure 40 is disposed between the light emitting portion 60 and the pressing portion 20 , and the light emitted by the light emitting portion 60 can pass through the trigger structure 40 and be guided and projected by the pressing portion 20 .

[0040] It can be understood that the trigger structure 40 is in contact with the pressing portion 20. When pressure is applied to the pressing portion 20 to cause the pressing portion 20 to move, the trigger structure 40 can be directly triggered, and the triggering of the trigger structure 40 can be avoided from affecting the projection of the light-emitting portion 60 on the pressing portion 20.

[0041] In one embodiment, the trigger structure 40 includes a trigger member 41 and a trigger spring 42 . The trigger member 41 is disposed on the support portion 70 . The trigger spring 42 is connected to the side of the pressing portion 20 facing the first circuit board 30 and is disposed opposite to the trigger member 41 .

[0042] like Figures 3 to 5As shown, the trigger spring 42 is arranged between the pressing portion 20 and the trigger member 41, so that when the pressing portion 20 is moved by force, the trigger member 41 can be controlled to work through the trigger spring 42. When the pressing portion 20 is not under force, the trigger spring 42 is reset and presses the pressing portion 20 to reset, so as to realize the control operation function of the button.

[0043] It can be understood that the trigger spring piece 42 is connected to the pressing part 20, and the light-emitting part 60 is arranged opposite to the pressing part 20. The pressing part 20 is subjected to force to drive the trigger spring piece 42 to deform and accumulate elastic force. At the same time, the trigger spring piece 42 avoids the light projection direction of the light-emitting part 60 to ensure the projection effect of the light-emitting part 60 and the pressing part 20.

[0044] like Figure 3 As shown, the light emitting portion 60 and the trigger member 41 are located on the same plane, and the trigger spring 42 is disposed opposite to the trigger member 41 .

[0045] It can be understood that the trigger member 41, the trigger spring 52, the pressing portion 20 and the light-emitting portion 60 are integrated into the support portion 70, which greatly reduces the space occupied by the first circuit board 30, facilitates the installation of components, improves installation efficiency and reduces costs.

[0046] In one embodiment, a relief opening is provided on the trigger spring 42 , and the light emitting portion 60 is disposed opposite to the relief opening.

[0047] In order to prevent the trigger spring piece 42 from affecting the light emitting portion 60 from projecting light toward the pressing portion 20 , a relief opening is provided on the trigger spring piece 42 so that the light from the light emitting portion 60 can pass through the relief opening and project onto the pressing portion 20 .

[0048] It can be understood that the avoidance opening is arranged at the center of the trigger spring piece 42. When the pressing part 20 is pressed, the pressing part 20 can block the avoidance opening and drive the trigger spring piece 42 to deform. At the same time, the light emitted by the light-emitting part 60 passes through the avoidance opening and is projected onto the pressing part 20, thereby realizing the function of the button pressing itself and preventing the trigger spring piece 42 from affecting the light transmission between the light-emitting part 60 and the pressing part 20.

[0049] It should be noted that the cross-sectional area of ​​the avoidance opening is larger than the 20° cross-sectional area of ​​the light-emitting portion.

[0050] It is understandable that the opening of the avoidance port is larger than the light-emitting portion, so that the light emitted by the light-emitting portion can pass through the trigger spring 42 as much as possible and be projected onto the pressing portion 20, ensuring the brightness of the light emitted by the pressing portion 20 and improving the user experience.

[0051] In one embodiment, the trigger structure 40 further includes a second circuit board 43 , which is disposed on the support portion 70 . The trigger member 41 and the light-emitting portion 60 are both disposed on the second circuit board 43 , and the second circuit board 43 is connected to the first circuit board 30 .

[0052] like Figure 3 and Figure 5 As shown, the second circuit board 43 is used to carry the trigger member 41 and the light-emitting portion 60, and the trigger member 41 and the light-emitting portion 60 are both electrically connected to the second circuit board 43, and the multiple pins on the supporting portion 70 are connected to the second circuit board 43, so that the first circuit board 30, the second circuit board 43, the multiple trigger members 41 and the light-emitting portion 60 are electrically connected, so that the light-emitting portion 60 can be triggered synchronously when the pressing portion 20 triggers the trigger spring 42.

[0053] It should be noted that the second circuit board 43 is disposed in the support portion 70 and is wrapped by the support portion 70 , and the trigger 41 and the light emitting portion 60 are both disposed on the side of the second circuit board 43 facing the pressing portion 20 .

[0054] In one embodiment, there are multiple triggering members 41 , and the multiple triggering members 41 are disposed around the light-emitting portion 60 . The triggering springs 42 are disposed opposite to the multiple triggering members 41 .

[0055] It can be understood that the multiple trigger members 41 are arranged opposite to the trigger spring 42. When the trigger spring 42 is driven to move by the pressing portion 20, the trigger spring 42 can contact the multiple trigger members 41 at the same time, thereby ensuring the stability of the trigger control of the light-emitting portion 60.

[0056] It can be understood that multiple trigger members 41 are arranged around the light-emitting portion 60, and the positions of multiple trigger members 41 and the light-emitting portion 60 in the support portion 60 are reasonably arranged to ensure that the trigger spring 42 can trigger multiple trigger members 41 while saving space in the support portion 70 and saving parts costs.

[0057] In order to facilitate the trigger spring 42 to be able to contact with multiple trigger members 41, as shown in FIG. Figure 3As shown, with the light-emitting portion 60 as the center, multiple trigger members 41 are distributed in a circular manner around the light-emitting portion 60, and the trigger spring 42 is arranged in a truncated cone shape, and the edge of the trigger spring 42 is arranged opposite to the multiple trigger members 41. The trigger spring 42 covers the light-emitting portion 60, and the avoidance is opposite to the light-emitting portion 60, and facilitates the trigger spring 42 to trigger multiple trigger members 41 at the same time.

[0058] It should be noted that the plurality of trigger members 41 are arranged at intervals, that is, a predetermined distance is set between two adjacent trigger members 41 to prevent the two adjacent trigger members 41 from being too close to each other and interfering with each other.

[0059] It is understandable that the truncated cone-shaped trigger spring piece 42 can ensure contact and triggering with multiple trigger members 41 during the deformation process, ensuring the stability of the triggering, and the truncated cone-shaped trigger spring piece 42 can also ensure the stability of the movement of the pressing part 20.

[0060] It can be understood that the light-emitting portion 60, the avoidance opening and the pressing portion 20 are in the same straight line, so that when the pressing portion 20 presses the trigger spring 42, the light of the light-emitting portion 60 can pass through the avoidance opening and be projected onto the pressing portion 20, thereby realizing the power on / off operation of pressing the button, and also realizing the marking of the pressing portion 20 through the light-emitting portion 60, which makes it easier for the user to find the button accurately.

[0061] In one embodiment, there is only one triggering member 41 , and the triggering member 41 is disposed on one side of the light emitting portion 60 .

[0062] In one embodiment, the pressing portion 20 includes a key pillar 22 . The key pillar 22 is disposed through the supporting portion 70 and is connected to the trigger spring 42 . The key pillar 22 guides light.

[0063] It is understandable that the button pillar 22 is plugged into the support portion 70 , and when the pressing pillar is moved by force, it can trigger the trigger spring 42 and the plurality of trigger members 41 to achieve a switch operation.

[0064] In order to improve the recognition of the prompt, a silk-screen projection pattern is provided on the surface of the button pillar 22 facing away from the light-emitting portion 60. When the light-emitting portion 60 projects light to the button pillar 22, the button pillar 22 guides the light and projects the projection pattern onto the display placement surface for easy user identification.

[0065] It is understandable that the key pillar 22 guides light to facilitate projection of the light of the light-emitting portion 60 .

[0066] In one embodiment, the button with projection light 100 further includes a housing 10 , a circuit board 30 is connected to the housing 10 , a button 21 is provided on the housing 10 , and the button 21 contacts the button support 22 , and the button 21 guides light.

[0067] In order to facilitate the user to press and drive the button pillar 22 , a button 21 is provided on the housing 10 , and the cross-sectional area of ​​the button 21 is larger than the cross-sectional area of ​​the button pillar 22 .

[0068] It can be understood that by enlarging the cross-sectional area of ​​the button 21 , the surface of the button 21 exposed outside the housing 10 can fully contact the surface of the user's finger, thereby facilitating the movement of the button 21 .

[0069] It can be understood that the button 21 is in contact with the button support 22 , which facilitates force transmission between the button 21 and the button support 22 and improves transmission efficiency.

[0070] It should be noted that the button 21 is made of transparent silicone to facilitate light transmission.

[0071] The present invention also proposes a display, which includes the button with projection light 100. The specific structure of the button with projection light 100 refers to the above embodiment. Since the present display adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0072] like Figure 6 As shown, the button with projection light 100 is arranged on the bottom surface of the display, so that the light of the button with projection light 100 is projected onto the placement surface of the display, making it easier for users to find the button.

[0073] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention specification and drawings under the technical concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention.
