[0032] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0033] See also Figure 1a 、 Figure 1b and Figure 2 , Figure 1a An exemplary side view of a trigger assembly according to some embodiments of the present disclosure is shown, wherein a portion where a trigger member is mounted is shown in a cross-sectional view. Figure 1b Shown Figure 1a A partial enlarged schematic diagram of part A in the middle. Figure 2 An exemplary cross-sectional view of a trigger member of a trigger assembly according to some embodiments of the present disclosure is shown. In some embodiments, the trigger assembly 100 includes a trigger member 1 and a frame 30 for mounting the trigger member 1. The trigger member 1 comprises an outer portion 10 and an inner portion 20 fixed to each other. The inner portion 20 includes a color layer 21 located adjacent to the outer portion 10, and the outer portion 10 is at least partially made of a transparent material. The frame 30 has a keyhole 31, and the trigger member 1 is at least partially accommodated within the keyhole 31. Furthermore, the outer portion 10 completely covers the outer surface of the color layer 21 along the depth direction of the keyhole 31, and the outer portion 10, along the outward side of the keyhole 31, is at least partially formed into a curved surface. As a result, the transparent portion of the outer portion 10 can project the structure and color of the color layer 211 outward, while the curved surface of the outer portion 10 can change the projected shape of the color layer 211 at different viewing angles, making it more three-dimensional.

[0034] Specifically, in this embodiment, the outer portion 10 of the trigger member 1 is generally formed as a curved plate-like body, with one side of the plate-like body being concave along its thickness, forming a concave portion 11. The inner portion 20 of the trigger member 1 is at least partially housed within this concave portion 11 and fixedly connected to the outer portion 10 therein. This connection can be achieved by integral molding, bonding with a transparent adhesive, or welding. The inner portion 20 of the trigger member 1 includes a color layer portion 21 adjacent to the concave portion 11 and the outer portion 10, and a fixing portion 22 disposed on the side of the color layer portion 21 facing away from the outer portion 10. The surface of the color layer portion 21 facing the outer portion 10 is provided with a color layer 211 having a specific color or logo pattern and / or a surface relief structure. This color, pattern, or relief structure can be achieved by, for example, a pigment coating, a material film, or surface engraving. The concave portion 11 of the outer portion 10 circumferentially surrounds the color layer portion 21 in a horizontal direction perpendicular to the depth direction of the keyhole 31, completely covering the color layer 211. While protecting and sealing the color layer 211, the transparent portion of the outer portion 10 circumferentially outward can further fully project the color and surface structure of the outer surface of the color layer portion 21, thereby enhancing the three-dimensional effect of the color layer portion 21 and improving its recognition.

[0035] The color layer portion 21 is generally formed into a plate shape, with one side of the color layer portion 21 being shaped to mate with the concave portion 11 of the outer portion 10, and the other side being provided with a fixing portion 22 protruding perpendicularly to the thickness thereof. In this embodiment, the fixing portion 22 includes a first leg 221, a second leg 222, and a third leg 223 spaced apart along a length of the color layer portion 21. The first leg 221 and the third leg 223 are configured to engage with the frame 30, while the second leg 222 is configured to contact a corresponding electronic or mechanical device to transmit command information. When the inner portion 20 and the outer portion 10 are processed by injection molding, the first leg 221 can be provided with a glue injection hole 2211, and the third leg 223 can be provided with an air hole or glue overflow hole 2231. The air hole or glue overflow hole 2231 respectively penetrates the inner portion 20 to connect with the outer portion 10. Therefore, during processing, the inner part 20 can be processed separately first, and the inner part 20 can be docked with a mold having the outer shape of the outer part 10. Injection molding is performed by injecting glue into the injection hole 2211, and gas or excess material is discharged with the help of air holes or overflow holes 2231, thereby facilitating the processing of the outer part 10, making the material in the outer part 10 more uniform, and reducing the generation of bubbles or other processing marks.

[0036] See also Figure 1a and Figure 1bThe frame 30 is the outer frame of the electronic device, made of a rigid material such as plastic or metal. A keyhole 31 extending toward the interior of the electronic device is defined on one side of the frame 30 facing the exterior. A locking groove 311 extending radially outward is defined on the radially inner wall of the keyhole 31. The inner portion 20 of the trigger member 1 at least partially extends into the keyhole 31. The distal end of the first leg 221, facing away from the color layer portion 21, protrudes radially outward of the keyhole 31, so that the distal end of the first leg 221 is at least partially received within the locking groove 311 and is retained by the locking groove 311 along the depth direction of the keyhole 31. In this embodiment, the position of the trigger member 1 relative to the keyhole 31 is determined by the fit between the first leg 221 and the locking groove 311. Preferably, the position is configured such that the outer surface of the color layer portion 21 adjacent to the outer portion 10 is flush with, or lower than, the outer surface of the frame 30 along the depth direction of the keyhole 31. In this way, external light projected from the side toward the outer portion 10 will not form reflections on the outer surface of the color layer portion 21, resulting in the color or structure on the color layer portion 21 not being noticed by the user, and the parts protruding from the frame are all transparent parts, thereby improving the consistency of the buttons in the entire device, and enhancing the recognition effect and aesthetics.

[0037] Furthermore, the frame 30 is provided with a trigger hole 32 and an element accommodating cavity 33. The trigger hole 32 overlaps with the keyhole 31 along the axial direction of the keyhole 31 and is aligned with the second leg 222 of the inner portion 20 along the same axial direction. The element accommodating cavity 33 is a cavity formed inside the frame 30 and is used to accommodate the element 42 to be triggered. One end of the trigger hole 32 is connected to the keyhole 31, and the other end is connected to the element accommodating cavity 33. A buffer 41 is provided inside the trigger hole 32. The buffer 41 is made of a flexible material such as rubber. One side of the buffer 41 abuts the second leg 222, and the other side abuts the trigger portion 421 of the element 42 to be triggered. As a result, when the trigger member 1 is pressed, the pressing force is transmitted through the buffer 41 to the trigger portion 421 of the element 42 to be triggered, triggering the element to perform the corresponding reaction action.

[0038] In this embodiment, the material of the outer portion 10 preferably has a light transmittance of 60% to 85%. The combined thickness of the outer portion 10 and the color layer 21 along the depth of the keyhole 31 is greater than 1 mm, and the ratio of the thickness of the outer portion 10 to the color layer 21 is between 6:5 and 1:1. As a result, the outer portion 10 transmits the color and structure of the outer surface of the color layer 21 while preventing users from observing any processing defects on the surface of the color layer 21, further enhancing the aesthetics of the product.

[0039] Those skilled in the art can understand that, although the above describes a scheme of triggering the to-be-triggered element 42 by pressing force to trigger the relevant reaction action, the above scheme is only an exemplary scheme, and the disclosure does not limit the specific form of the trigger piece 1 and the specific triggering mode of the to-be-triggered element 42.

[0040] For example, see Figure 3 , Figure 3 An exemplary partial cross-sectional view of the trigger assembly of some embodiments of the disclosure is shown. In the illustrated embodiment, the to-be-triggered element 42 is an inductive trigger switch, i.e., its triggering mode is not a mechanical pressing trigger, but is triggered by means such as light, voltage, resistance, etc. Thus, the trigger piece 1 can be fixedly arranged in the key hole 31 of the frame 30 by means of size fitting, adhesive bonding or welding connection, etc., without the need to transmit a key stroke signal, and only needs to satisfy the material properties that can transmit corresponding light or electrical signals, etc. The to-be-triggered element 42 is fixedly arranged between the inner side portion 20 of the trigger piece 1 and the frame 30, and the triggering portion 421 thereof is connected with the inner side portion 20 of the trigger piece 1 by means of electrical connection, etc., to receive the triggering information transmitted through the trigger piece 1. In the case of arranging the trigger piece 1 to be fixedly connected with respect to the frame 30, the structural strength of the connection between the trigger piece 1 and the frame 30 can be improved, avoiding the wear and tear caused by long-term friction between the moving parts and the frame 30, and enhancing the service life. In addition, arranging the trigger piece 1 to be fixed with respect to the frame 30 can also reduce the external gap of the electronic device, enhancing the waterproof performance of the electronic device.

[0041] In this embodiment, the color layer portion 21 of the trigger piece 1 is also transparent or translucent, so that when the to-be-triggered element 42 is a light inductive element, the external light information can be received through the trigger piece 1. However, those skilled in the art can understand that in some embodiments not shown, even if the to-be-triggered element 42 is a mechanical pressing trigger element or a voltage, resistance inductive trigger element, the color layer portion 21 of the trigger piece 1 can also be arranged to be transparent or translucent. At this time, the surface of the color layer portion 21 adjacent to the outer side portion 10 forms a corresponding color or surface structure, which still can play a corresponding identification or decoration role.

[0042] It is understood by those skilled in the art that the above respectively describes a scheme for triggering the trigger element 42 by pressure, and a scheme for triggering the trigger element 42 by an induction signal such as light, resistance or voltage. However, the triggering methods described in the above two schemes and other similar triggering methods are not independent of each other, but can be used in combination. For example, in some embodiments not shown, a pressure triggering element and an induction triggering element are provided on the frame 30 at the same time. The two triggering elements are respectively used to receive different triggering information and output different triggering signals in response to the corresponding triggering information. When the user touches the surface of the triggering member 1 or presses the surface of the triggering member 1, the corresponding electronic device can be controlled to produce two different reaction actions, thereby achieving richer and more detailed control functions without increasing the number of buttons, further improving the user experience.

[0043] Further, see Figure 4 , Figure 4 An exemplary partial cross-sectional view of a trigger assembly according to some embodiments of the present disclosure is shown. Figure 4 In the illustrated embodiment, the transparency of the color layer 21 is lower than that of the outer portion 10. As a result, the color or surface structure of the color layer 21 at its interface with the outer portion 10 is enhanced by the material of the color layer 21 within, enhancing its visibility from an external perspective. A locking groove 311 extending radially outward from the keyhole 31 is provided within the keyhole 31. The fixing portion 22 of the trigger member 1 is disposed circumferentially outward of the color layer 21 and extends outwardly into the locking groove 311 to retain the trigger member 1 relative to the frame 30. Therefore, if the color layer 21 is also transparent or translucent, because the fixing portion 22 is offset from the outer portion 10 and the color layer 21 in the direction of their overlap, the projection of the fixing portion 22 will not be projected through the outer portion 10 and the color layer 21, thereby preventing its projection from being confused with the projection of the outer surface of the color layer 21. In addition, a dark covering layer 212 is provided on the side of the inner portion 20 facing away from the outer portion 10. The dark covering layer 212 is a darker plating or coating, which can prevent the projection of other structures on the side of the inner portion 20 facing away from the outer portion 10 from being confused with the outer surface projection of the color layer portion 21.

[0044] In this embodiment, a warning light 44 is further provided on the side of the inner portion 20 facing away from the outer portion 10. Specifically, a lamp holder 432 is provided on the side of the to-be-triggered element 42 adjacent to the inner portion 20, which is formed by an inward depression of its surface. The warning light 44 is fixedly arranged inside the lamp holder 432 and is completely accommodated by the lamp holder 432. The warning light 44 is a light-emitting element such as a white or colored LED lamp bead. Its light-emitting portion is arranged toward the inner portion 20, and its connection terminal portion is electrically connected to the to-be-triggered element 42. Therefore, when the trigger member 1 triggers the to-be-triggered element 42, the warning light 44 will be lit at the same time, projecting light onto the outer surface of the color layer portion 21 to highlight the color and surface structure of the outer surface. Furthermore, by setting the warning light 44, the lighting effect can be maintained for a period of time (for example, 2 seconds) after the key is released to avoid the finger completely covering the key and the emitted lighting effect being unnoticeable.

[0045] At the same time, the flashing of the prompt light 44 can also serve as feedback prompts on whether the triggering element 42 is successfully triggered, further improving the user experience. Alternatively, the prompt light 44 can serve as a breathing light, and the outer surface of the triggering member 1 can be a diffuse reflection surface. Thus, the entire button area will form a breathing light effect, which is convenient for use as a prompt signal.

[0046] See also Figure 5 , Figure 5 An exemplary partial cross-sectional view of a trigger assembly according to some embodiments of the present disclosure is shown. In this embodiment, the trigger assembly further includes a light sensor 45. The light sensor 45 is disposed on the bottom side of the inner portion 20, and both the outer portion 10 and the inner portion 20 are fixedly connected to the frame 30 by bonding or other means. The trigger member 1 further includes a second color layer 60, which at least partially covers the outer portion 10, and the side of the second color layer 60 proximal to the trigger member 1 forms a reflective surface 62. Specifically, the light sensor 45 is a TOF (time of fly) light sensor, and the second color layer 60 has a channel portion 61, which is a transparent portion or a hollow portion on the second color layer 60. The channel portion 61 can, together with the transparent portions of the outer portion 10 and the inner portion 20, form an optical channel aligned with the light receiving portion of the light sensor 45. Thus, the light sensor 45 can detect whether a light-blocking object (e.g., a user's finger) covers the channel portion 61, thereby emitting a corresponding control signal in response to a key press. The reflective surface 62 can reflect light inside the trigger member 1 , thereby gathering the external ambient light penetrating through the channel portion 61 and projecting it onto the light receiving portion of the light sensor 45 , thereby improving the sensitivity of the light sensor 45 .

[0047] Meanwhile, the light sensor 45 also has a lamp bead mounting seat 452, and the prompt lamp 44 is mounted on the lamp bead mounting seat 452, and the light emitting part thereof is arranged towards the passage part 61 of the second color layer 60. Thus, when the trigger 1 is pressed, the prompt lamp 44 can emit light in response to the trigger signal of the light sensor 45, and the light reaches the outside through the transparent part of the inner side part 20 and the outer side part 10 and the passage part 61, so as to prompt the user that the trigger 1 has been triggered. In addition, by setting the shape of the passage part 61, the function corresponding to the trigger 1 can be prompted, for example, the shape of the passage part 61 is set as a power symbol, a volume increase / decrease symbol, etc.

[0048] Referring to Figure 6 , Figure 6 An exemplary cross-sectional view of a trigger of a trigger assembly according to some embodiments of the present disclosure is shown. In Figure 5 In the embodiment shown, the outer surface of the color layer part 21 adjacent to the outer side part 10 also comprises a concave part 213 formed by being concave inward along the thickness direction of the color layer part 21, and the part of the outer side part 10 adjacent to the concave part 213 is correspondingly formed with a convex part 101. In this embodiment, the concave part 213 and the convex part 101 are respectively formed in the central part of the plate surface of the color layer part 21 and the outer side part 10. Thus, the convex part 101 forms a structure similar to a convex lens, which can magnify the color or surface structure of the outer surface of the color layer part 21 by refraction of light, so as to make it more obvious and stereoscopic.

[0049] In addition, in some embodiments not shown, the surface of the color layer part 21 can form a concave reflecting surface surrounding the prompt lamp 44, so as to form a spotlight effect of the light emitting part similar to a flashlight or a spotlight, so that the directivity and light intensity of the prompt lamp light are improved.

[0050] The trigger assembly according to the embodiments of the present disclosure can protect the color layer part in the trigger by setting the trigger to comprise a transparent or translucent outer side part and an inner side part covered by the outer side part, and setting the inner side part to comprise a color layer part adjacent to the outer side part, and setting the outer side part to have a curved surface, so as to make the color layer part in the trigger more stereoscopic in vision and improve the recognition thereof.

[0051] Referring to Figure 7 , Figure 7An exemplary perspective view of a mobile terminal showing some embodiments of the present disclosure is shown. The mobile terminal 200 comprises a host 300, a trigger assembly 100 according to the above embodiments disposed outside the host 300, and a function button 400. In this embodiment, the mobile terminal 200 is a portable electronic device such as a mobile phone, earphone, watch, tablet computer, etc. The trigger assembly 100 is disposed outside the mobile terminal 200, and the function button 400 is a button triggered in a different way from the trigger of the trigger assembly 100. For example, when the trigger assembly 100 is a power button, the function button 400 is a volume control button. The outer surface of the trigger assembly 100 is formed to have a surface structure different from that of the function button 400, such as having a different contour shape or surface texture. At this time, by setting the exposed surfaces of the trigger assembly 100 and the function button 400 to have different surface structures, the trigger and the function button 400 can have different tactile sensations, so that the user can know the button function without visually checking the button surface, improving the use experience of the mobile terminal 200 and reducing the probability of accidental triggering.

[0052] In addition, since the mobile device such as a mobile phone has the area suitable for finger pressing concentrated in a fixed area when held by one hand, the buttons are generally designed to be relatively close, and the buttons are often designed to correspond to different functions, some of which are suitable for operation without relying on vision, such as instant double-click to wake up the camera, long press to wake up the voice assistant, and start the recording function. When the button needs to be used to enable such functions, the trigger assembly according to the above embodiments can be used to distinguish from other buttons by the different pressing tactile sensation and pressing start mode, reduce the probability of accidental triggering, and improve the use experience.

[0053] Although the embodiments of the present disclosure have been shown and described herein, it will be apparent to those skilled in the art that many modifications, changes and substitutions can be made thereto without departing from the spirit and scope of the present disclosure. It is to be understood that various alternatives to the embodiments of the present disclosure described herein can be employed in practicing the present disclosure.
