[0038] The following describes the present invention based on embodiments, but the present invention is not limited to these embodiments. In the following detailed description of the present invention, some specific details are described in detail. In order to avoid obscuring the essence of the present invention, well-known methods, processes, procedures, and components are not described in detail.

[0039] In addition, those of ordinary skill in the art should understand that the drawings provided herein are for illustrative purposes only, and the drawings are not necessarily drawn to scale.

[0040] Unless the context clearly requires otherwise, the words such as "including", "comprising", and the like in the whole specification and claims should be interpreted as the meaning of including rather than exclusive or exhaustive; that is, the meaning of "including but not limited to".

[0041] In the description of the present invention, it should be understood that the terms "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying relative importance. In addition, in the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0042] The present invention provides an electronic device, such as an infrared touch interactive screen or a capacitive touch interactive screen, etc. The electronic device includes a mounting component, such as Figure 1 , Figure 2 As shown, the mounting component includes Assembly 1, and Assembly 1 includes a functional component 12 having a switch button. In addition, Assembly 1 further includes a control component 11 connected to the functional component 12. The electronic device also includes a frame, and the mounting component is installed within the frame.

[0043] As Figures 3 - 5 shown, the functional component 12 includes a switch button 121, a first light-transmitting part 122, a second light-transmitting part 123, and a fixed connection part 124. The first light-transmitting part 122 and the second light-transmitting part 123 are arranged on the same side of a central plane of the switch button 121. The switch button 121 is connected to the corresponding fixed connection part 124 through elastic parts 125 at two positions, that is, the switch button 121 is respectively connected to a fixed connection part 124 through an elastic part 125 at each position, so that the switch button 121 can be pressed in its own axial direction. The switch button 121, the first light-transmitting part 122, the second light-transmitting part 123, the elastic parts 125, and the fixed connection part 124 are integrally formed. That is to say, the switch button 121, the first light-transmitting part 122, the second light-transmitting part 123, the elastic parts 125, and the fixed connection part 124 are formed by one-time processing, such as integral injection molding. Among them, the above-mentioned central plane is parallel to the axial direction of the switch button 121 (that is, the direction where the central axis of the switch button 121 is located, and this direction is consistent with the pressing direction of the switch button 121). The above-mentioned two positions are respectively located on the above-mentioned central plane, that is, the two positions are the two junctions of the edge of the switch button 121 and the above-mentioned central plane.

[0044] The above functional component 12 is provided with a switch button 121, a first light-transmitting part 122, and a second light-transmitting part 123 integrally formed. After such a setting, the electronic device only needs to set one installation space, which can reduce the space occupied by the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123 in the electronic device. Compared with the way of providing installation spaces for the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123 respectively, the space utilization rate of the electronic device is significantly improved; and by arranging the first light-transmitting part 122 and the second light-transmitting part 123 on the same side of a central plane of the switch button 121, the volume of the entire functional component 12 can be further reduced, and the space occupied by the functional component 12 in the electronic device can be reduced. When processing such a functional component 12, only one mold needs to be opened to simultaneously form the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123, reducing the number of molds and being able to reduce the mold cost; at the same time, by adopting such a functional component 12, during assembly, the number of assembled parts is reduced, the assembly process is saved, and the assembly efficiency can be improved. In addition, considering that in such an integrally formed functional component 12, if the switch button 121 is directly connected to the fixed connection part 124, the elasticity of the switch button 121 during operation is poor, affecting the user experience. In the present invention, the switch button 121 is connected to the fixed connection part 124 through an elastic part 125 to increase the elasticity when the switch button 121 is pressed and improve the user's operation feel. In addition, the present invention also makes the positions of the two elastic parts 125 located on the above-mentioned central plane to further increase the operation feel of the switch button 121.

[0045] Specifically, as Figure 3 , Figure 4 shown, the functional component 12 further includes a carrier part 126. The first light-transmitting part 122 and the second light-transmitting part 123 are both arranged on the carrier part 126, and the two elastic parts 125 are respectively connected to both ends of the carrier part 126 through the fixed connection part 124.

[0046] A hollow structure 1261 can be arranged on the carrier part 126. Referring to Figure 3 , a hollow structure 1261 is arranged on the carrier part 126 in the areas of the first light-transmitting part 122 and the second light-transmitting part 123, which is beneficial to the molding of the functional component 12, and at the same time can reduce the weight of the functional component 12 and save materials.

[0047] On the back side of the functional component 12, that is, the light-emitting side of the first light-transmitting part 122 (i.e., the side close to the control part 11 after the functional component 12 and the control part 11 are installed), the carrier part 126 is recessed relative to the fixed connection part 124. When the functional component 12 and the control part 11 are installed, the fixed connection part 124 is attached to the control part 11 to avoid large-area contact between the functional component 12 and the control part 11 and increase the installation stability of the two.

[0048] On the light incident side of the first light-transmitting part 122, the fixed connection part 124 and the carrier part 126 can be in the same plane or can be recessed relative to the carrier part 126.

[0049] The switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123 can be in a plate-like structure. On the light incident side of the first light-transmitting part 122, the three are arranged on the same plane as the carrier part 126. In a preferred embodiment, refer to Figure 3 , on the light incident side of the first light-transmitting part 122, the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123 all protrude from the carrier part 126, that is, the three are all in a columnar structure, such as a cylindrical structure, to facilitate the operation of the switch button 121 and enable external light and infrared light to enter the first light-transmitting part 122 and the second light-transmitting part 123 better. In this embodiment, of course, on the light incident side of the first light-transmitting part 122, among the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123, only one or two of them can also protrude from the carrier part 126.

[0050] Furthermore, when the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123 are all in a cylindrical structure, the distances from the central axis of the first light-transmitting part 122 and the central axis of the second light-transmitting part 123 to the central axis of the switch button 121 are equal, so as to better reduce the volume of the functional component 12.

[0051] Specifically, on the light incident side of the first light-transmitting part 122, when the switch button 121 protrudes from the carrier part 126, the switch button 121 can be set into a stepped structure, such as Figure 3 shown, the switch button 121 includes a small section 1211 and a large section 1212 connected to each other. On the light incident side of the first light-transmitting part 122, the small section 1211 protrudes from the carrier part 126.

[0052] In one embodiment, in order to facilitate molding and manufacturing, the switch button 121 can be set into a cover-shaped structure, and the opening of the cover-shaped structure faces the control part 11, that is, on the back side of the functional component 12, the switch button 121 is in a concave structure. Especially when the switch button 121 protrudes from the carrier part 126 on the light incident side of the first light-transmitting part 122, the distance between the switch button 121 and the switch element 111 in the above axial direction is increased, the pressing stroke of the switch button 121 is increased, and the difficulty of triggering the switch element 111 is reduced. During long-term use, it may cause elastic failure of the switch button 121 and the elastic part 125, and even cracking. To solve this problem, in the present invention, on the back side of the functional component 12 (that is, the inner side of the cover-shaped structure), the switch button 121 is provided with a convex structure 1213, such as Figure 4As shown, the convex structure 1213 protrudes towards the control member 11 and faces the switch element 111 to reduce the pressing stroke of the switch button 121 and improve the lifespan of the functional component 12. When the switch button 121 is in a cover-shaped structure, the convex structure 1213 is arranged on the inner bottom wall of the cover-shaped structure and has a gap with the inner side wall of the cover-shaped structure to increase the elasticity of the switch button 121 and facilitate the molding of the functional component 12. Among them, the convex structure 1213 can be a columnar structure, such as a cylindrical structure or a prismatic structure, for easy molding.

[0053] Similarly, the first light-transmitting portion 122 and the second light-transmitting portion 123 can also be arranged in a cover-shaped structure for easy molding. However, this method increases the distance between the first light-transmitting portion 122 and the light-sensing element 112 and the distance between the second light-transmitting portion 123 and the infrared receiving element 113, resulting in the incident light (i.e., ambient light and infrared light) passing through the first light-transmitting portion 122 and the second light-transmitting portion 123 needing to travel through a relatively long distance in the air medium before reaching the light-sensing element 112 and the infrared receiving element 113, leading to problems such as weakening of the incident light energy. The ambient light and infrared light received by the light-sensing element 112 and the infrared receiving element 113 are reduced, affecting the accuracy of the control member 11's judgment of the outside world. For this reason, on the back side of the functional component 12, light guide columns 1221 are arranged on both the first light-transmitting portion 122 and the second light-transmitting portion 123 to minimize the transmission path of the air medium as much as possible, reduce the influence on the incident light entering the first light-transmitting portion 122 and the second light-transmitting portion 123, and improve the control accuracy of the control member 11. Of course, light guide columns 1221 can also be arranged only on the first light-transmitting portion 122 or the second light-transmitting portion 123. Specifically, the light guide column 1221 can be a prismatic structure. For example, the light guide column 1221 extends from the inner bottom wall of the cover-shaped structure towards the control member 11 and has a gap with the inner side wall of the cover-shaped structure. In addition, to prevent the light guide column 1221 from squeezing the light-sensing element 112 and the infrared receiving element 113, after the functional component 12 and the control member 11 are installed, there are gaps between the light guide column 1221 and the light-sensing element 112 and the infrared receiving element 113.

[0054] It should be noted that the present invention is not limited to the situation where the convex structure 1213 and the light guide column 1221 can be arranged only when the switch button 121, the first light-transmitting portion 122, and the second light-transmitting portion 123 are in a cover-shaped structure. When the switch button 121, the first light-transmitting portion 122, and the second light-transmitting portion 123 are in other structures, the convex structure 1213 and the light guide column 1221 can also be arranged.

[0055] In a preferred embodiment, the switch button 121 is connected to the fixed connection portion 124 only at the above two positions (i.e., two positions located at the above center surface of the switch button 121), and the other areas are suspended (i.e., not connected to the fixed connection portion 124 and the carrier portion 126) to increase the elasticity of the switch button 121. Of course, the connection position of the switch button 121 is not limited to the above two positions, and the switch button 121 can also be connected to the fixed connection portion 124 or the carrier portion 126 through more other positions.

[0056] The elastic portion 125 may be in a strip-shaped structure, with one end connected to the fixed connection portion 124 and the other end connected to the switch button 121 . When the switch button 121 is in a stepped structure, the elastic portion 125 may be connected to the large section 1212 of the switch button 121 .

[0057] Preferably, the elastic portion 125 is a U-shaped structure, and the opening direction of the U-shaped opening is toward the fixed connection portion 124. Figure 3 As shown, at a connection position of the switch button 121, in a corresponding group of elastic parts 125 and the fixed connection part 124, one end of the opening of the U-shaped structure is connected to the fixed connection part 124, and the other end of the opening is connected to the switch button 121 (when the switch button 121 is a stepped structure, it can be connected to the large section 1212 of the switch button 121). The U-shaped structure can increase the elasticity of the elastic part 125. The thickness of the elastic part 125 can be less than the thickness of the fixed connection part 124 to increase the elasticity of the elastic part 125. Specifically, the elastic part 125 as a whole extends to the side away from the first light-transmitting part 122. Further, on the side of the switch button 121 away from the first light-transmitting part 122, the elastic part 125 does not exceed the switch button 121, so as to ensure that the elastic part 125 has sufficient elasticity and at the same time reduce the volume of the functional component 12 as much as possible. When the switch button 121 is connected only at the above two positions (i.e., two positions passing through the center surface of the switch button 121), the U-shaped grooves of the two elastic parts 125 are connected to each other along the outer periphery of the switch button 121. The above thickness refers to the dimension of the switch button 121 in the axial direction.

[0058] When the fixed connection portion 124 is recessed relative to the carrier portion 126, the side of the elastic portion 125 connected to the fixed connection portion 124 is connected to the fixed connection portion 124 through the transition section 1252. Figure 3 , one side of the elastic part 125 connected to the fixed connecting part 124 is defined as the connecting section 1251, and the transition section 1252 extends in the opposite direction of the depression of the fixed connecting part 124 and is connected to the connecting section 1251. The two form a bending structure to further increase the elasticity of the elastic part 125 and enhance the user's feel of pressing the switch button 121.

[0059] Among them, the control member 11 can be a control circuit board, such as a PCBA (Printed Circuit Board Assembly), on which various electronic components are provided, such as Figure 6 As shown, the control member 11 has a switch element 111, a light sensing element 112, and an infrared receiving element 113 that are respectively arranged corresponding to the switch button 121, the first light transmitting portion 122, and the second light transmitting portion 123 in the functional component 12. The switch element 111 can be a button switch to control the opening and closing of the electronic device; the light sensing element 112 is used to sense the ambient light to adjust display parameters such as the brightness of the display screen on the electronic device; the infrared receiving element 113 can be an infrared remote control receiving element for receiving operation signals from operating members such as a remote control, thereby realizing the operation of the user on the display screen. After the functional component 12 and the control member 11 are installed, the switch button 121 and the switch element 111 are arranged opposite to each other to realize the operation of the switch element 111 by operating the switch button 121; the first light transmitting portion 122 and the light sensing element 112 are arranged opposite to each other to allow external light to enter the light sensing element 112 through the first light transmitting portion 122; the second light transmitting portion 123 and the infrared receiving element 113 are arranged opposite to each other to allow the infrared signal to enter the infrared receiving element 113 through the second light transmitting portion 123. With such an arrangement, the switch element 111, the light sensing element 112, and the infrared receiving element 113 can be protected by the switch button 121, the first light transmitting portion 122, and the second light transmitting portion 123.

[0060] When the switch button 121 is pressed, in order to remind the user whether the button pressing is successful, the control member 11 also has a switch power indicator 114. The switch power indicator 114 is arranged beside the switch element 111. When the control member 11 and the functional component 12 are installed together, the switch power indicator 114 is also opposite to the switch button 121, so that when the switch power indicator 114 lights up, the light can pass through the switch button 121 and be recognized by the user.

[0061] One switch power indicator 114 can be provided, and it indicates the opening or closing of the electronic device by extinguishing and lighting. For example, when the switch element 111 is pressed by the switch button 121, if the electronic device is turned on, the switch power indicator 114 lights up; multiple switch power indicators 114 (such as two, three, or more) can also be provided. The multiple switch power indicators 114 can be set to different colors, such as Figure 6 As shown, two switch power indicators 114 are respectively arranged on both sides of a central plane of the switch element 111 (this central plane can be perpendicular, parallel, or at any other angle to the above-mentioned central plane of the switch button 121). Of course, the switch power indicator 114 can also indicate other opening and closing signals of the electronic device, which can be specifically set according to the product requirements.

[0062] When a power switch indicator light 114 is provided, when the power switch indicator light 114 is on, its light may enter the first light-transmitting portion 122, causing misjudgment of the light sensing element 112 and affecting the control accuracy of the display parameters of the electronic device. In order to solve the above problem, in one embodiment of the present invention, a light blocking portion 127 is also integrally formed between the switch button 121 and the first light-transmitting portion 122, that is, the functional component 12 is also provided with a light blocking portion 127, and the light blocking portion 127 is arranged between the switch button 121 and the first light-transmitting portion 122 to block the light of the power switch indicator light 114 from entering the first light-transmitting portion 122 as much as possible, thereby reducing the impact on the light sensing element 112.

[0063] Furthermore, on the back side of the functional component 12, the light blocking portion 127 protrudes from the first light-transmitting portion 122 to better block the light of the switch power indicator light 114. Furthermore, when the switch button 121 is a cover-shaped structure, on the back side of the functional component 12, the switch button 121 extends as far as possible toward the control member 11, and is even arranged in the same plane with the fixed connection portion 124. After such arrangement, the gap between the switch button 121 and the control member 11 on this side can be reduced to prevent the light of the switch power indicator light 114 on this side from directly entering the light sensing element 112 through the gap between the switch button 121 and the control member 11 as much as possible; and when the switch button 121 and the fixed connection portion 124 are in the same plane, when the functional component 12 and the control member 11 are installed, the fixed connection portion 124 and the light blocking portion 127 are in contact with the control member 11, which not only increases the strength of the two fixed connection portions 124, but also ensures the stability of the connection between the functional component 12 and the control member 11 under a smaller contact area.

[0064] It can be understood that a light blocking portion 127 may also be provided between the switch button 121 and the second light-transmissive portion 123 , and the light blocking portions 127 provided at two positions may be connected to each other to increase the strength of the light blocking portions 127 .

[0065] On the light incident side of the first light-transmitting portion 122, the light-blocking portion 127 protrudes from the carrier portion 126, and especially when the switch button 121 protrudes from the carrier portion 126 on this side, the light of the switch power indicator light 114 can be better blocked from entering the first light-transmitting portion 122. Further, in the embodiment where the switch button 121 is a stepped structure, preferably, on this side, the end of the light-blocking portion 127 exceeds the end of the large section 1212.

[0066] The light shielding portion 127 may be a plate-like structure, such as a flat plate structure or a curved structure. When the light shielding portion 127 is a curved structure, the strength of the light shielding portion 127 can be increased. Figure 3As shown, the light-blocking portion 127 has a curved structure, and the bending direction thereof is preferably away from the switch button 121. The light-blocking portion 127 extends along the circumferential direction of the switch button 121, and its two ends are respectively connected to the corresponding fixed connection portions 124. Specifically, the light-blocking portion 127 can have an arc-shaped plate structure or be formed by bending and connecting multiple sub-plates, and is disposed around the outer periphery of the switch button 121.

[0067] The surface of the light-blocking portion 127 can be a smooth surface or a matte surface. When it is a matte surface, it can better block the light of the switch power indicator 114 from entering the first light-transmitting portion 122. Preferably, regardless of the structure of the surface of the light-blocking portion 127, in order to better block the light of the switch power indicator 114 from entering the first light-transmitting portion 122, a light-blocking coating is further provided on the light-blocking portion 127. The light-blocking coating can be a black coating or other coatings with light absorption or light reflection properties.

[0068] When the light-blocking portion 127 is provided on the switch button 121, the control member 11 further has a vacant area 115. The components on the control member 11 (including the switch element 111, the light sensing element 112, the infrared receiving element, the switch power indicator 114, and other components) are disposed outside the vacant area 115. After the functional component 12 and the control member 11 are assembled, the vacant area 115 is opposite to the light-blocking portion 127 to prevent the light-blocking portion 127 from squeezing or even damaging the components in this area when the functional component 12 and the control member 11 are installed.

[0069] Optionally, at least part of the contour of the vacant area 115 is adapted to the contour of the lower surface of the light-blocking portion 127 to minimize the occupied space of the vacant area 115 on the control member 11, thereby providing greater installation flexibility for the arrangement of each component on the control member 11. Refer to Figure 4 , the vacant area 115 has a strip structure, and its two ends can extend to the edge of the control member 11.

[0070] It can be understood that components cannot be provided in the area on the control member 11 corresponding to the fixed connection portion 124. Therefore, on the back side of the functional component 12, the vacant area 115 extends to the area on the control member 11 corresponding to the fixed connection portion 124. In this way, when the light-blocking portion 127 and the fixed connection portion 124 are in the same plane on this side, the light-blocking portion 127, the fixed connection portion 124, and the vacant area 115 are in contact, and can also play a better light-blocking role.

[0071] In the above embodiments, regardless of how the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123 are arranged, the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123 are all semi-transparent or fully transparent structures to allow light and infrared signals to pass through; when the control member 11 is provided with a switch power indicator light 114, in order to allow the light of the switch power indicator light 114 to pass through, the switch button 121 can be partially fully transparent or semi-transparent, or can be entirely fully transparent or semi-transparent.

[0072] In the above embodiments, the functional component 12 can be integrally formed by injection molding or by machining. After the functional component 12 is processed and formed, part of it (including part of the area of the switch button 121, the first light-transmitting part 122, and the second light-transmitting part 123) can be made into a fully transparent or semi-transparent structure through spraying or a combination of spraying and engraving methods for easy light transmission, and the rest is an opaque structure.

[0073] Among them, the functional component 12 can be directly connected to the control member 11, such as by snap connection, bonding, or screw connection; it can also be indirectly connected through other components.

[0074] In one embodiment, the functional component 12 is further provided with a first connection hole 1241. Specifically, the first connection hole 1241 is provided on the fixed connection part 124, for example, the first connection hole 1241 is provided on both fixed connection parts 124. Correspondingly, the control member 11 has a second connection hole 116 correspondingly arranged with the first connection hole 1241, and the functional component 12 and the control member 11 are connected and locked by a fastener 3 (such as a screw) passing through the first connection hole 1241 and the second connection hole 116.

[0075] Continue to refer to Figures 1 - 4 , the functional component 12 is further provided with a positioning pin 1242. Correspondingly, the control member 11 has a first positioning hole 117 correspondingly arranged with the positioning pin 1242. When the functional component 12 and the control member 11 are installed, the positioning pin 1242 is inserted into the first positioning hole 117 to improve the installation accuracy between the functional component 12 and the control member 11, and ensure the relative position accuracy of each component on the control member 11 and the corresponding structure on the functional component 12, such as the position accuracy of the switch element 111, the switch power indicator light 114 and the switch button 121, the position accuracy of the light sensing element 112 and the first light-transmitting part 121, and the position accuracy of the infrared receiving element 113 and the second light-transmitting part 123, thereby ensuring the performance of the entire assembly 1. Specifically, the positioning pin 1242 can be provided on the fixed connection part 124 or the carrier part 126, such as Figure 4As shown, each fixed connection part 124 is provided with a positioning pin 1242, and the carrier part 126 is also provided with a positioning pin 1242. The positioning pin 1242 on the carrier part 126 can be located between the first light-transmitting part 122 and the second light-transmitting part 123. Correspondingly, the control part 11 is respectively provided with a first positioning hole 117 at the corresponding position. In this way, by positioning the control part 11 and the functional component 12 at three positions approximating a triangle at the edge of the functional component 12, the assembly accuracy of the two can be better improved.

[0076] When the control component 11 is provided with a vacant area 115, the second connecting hole 116 and the first positioning hole 117 can be arranged in the vacant area 115. It is worth noting that at this time, in the projection along the thickness direction of the control component 11 (i.e., the axial direction of the switch button 121), the second connecting hole 116 and the first positioning hole 117 are located on the outside of the light blocking portion 127.

[0077] It should be noted that the positioning method between the control component 11 and the functional component 12 is not limited to the above method. A positioning pin may be provided on the control component 11, and a first positioning hole may be provided on the functional component 12; or one of the control component 11 and the functional component 12 may be provided with a limit baffle, and the other may be directly installed in fit with the limit baffle.

[0078] The mounting assembly also has a mounting bracket 2, such as Figure 5 As shown, the mounting bracket 2 includes a first mounting portion 21, a second mounting portion 22, and a connecting portion 23 connecting the first mounting portion 2 and the second mounting portion 22. The first mounting portion 21 and the second mounting portion 22 can be located on the same side of the connecting portion 23, or on opposite sides of the connecting portion 23. The assembly 1 is installed on the first mounting portion 21. Specifically, the control component 11 is closer to the first mounting portion 21 than the functional component 12, and the control component 11 can be directly attached to the first mounting portion 21. By adding the mounting bracket 2, support can be provided for the assembly 1. At the same time, two mounting portions are provided, so that the assembly 1 and other mounting components (when assembled into an electronic device, it refers to the frame of the electronic device) are connected to different positions respectively, which can avoid damage to the assembly 1 during the installation of the mounting components as much as possible, and further improve the reliability of the assembly 1; and when the assembly 1 is installed in the electronic device, it can facilitate the installation of the assembly 1.

[0079] The assembly 1 can be mounted on the mounting bracket 2 by means of snap connection, bonding or screw connection, such as Figure 2As shown, the mounting assembly further includes a fastener 3. The fastener 3 is used to fasten and mount the functional component 12 and the control member 11 together to the mounting bracket 2. Further, the functional component 12, the control member 11, and the mounting bracket 2 can be locked by the same fastener 3. Specifically, a threaded hole corresponding to the second connection hole 116 is provided on the first mounting portion 21. In a set of corresponding first connection holes 1241, second connection holes 116, and threaded holes 211, the fastener 3 sequentially passes through the first connection hole 1241, the second connection hole 116, and is threadedly locked with the threaded hole 211. With the above structure, the volume of the mounting assembly can be further reduced, and assembly is facilitated.

[0080] Further, a positioning mechanism is provided between the first mounting portion 21 and the assembly 1. For example, a second positioning hole 212 is provided on the first mounting portion 21, and the second positioning hole 212 is correspondingly arranged with the first positioning hole 117. In a set of corresponding positioning pins 1242, first positioning holes 117, and second positioning holes 212, the positioning pin sequentially passes through the first positioning hole 117 and the second positioning hole 212, that is, the functional component 12, the control member 11, and the mounting bracket 2 are positioned together to further reduce the volume of the mounting assembly. Of course, the first mounting portion 21 and the assembly 1 can also be provided with a positioning mechanism separately.

[0081] In a preferred embodiment, the first mounting portion 21 and the second mounting portion 22 are oppositely arranged. Continuing to refer to Figure 2 , Figure 5 , the first mounting portion 21 and the second mounting portion 22 both extend in a direction away from the connecting portion 23, that is, the mounting bracket 2 has an approximately U-shaped structure. When the mounting assembly is mounted on the frame, a protrusion can be provided on the frame, and the protrusion is inserted into the U-shaped groove formed by the mounting bracket 2 to increase the stability of the mounting of the mounting assembly to the frame; and by providing the mounting bracket 2 with a U-shaped structure, the reliability of the connection between the mounting bracket 2 and the frame can be increased, providing stable support for the assembly 1 and reducing the probability of failure of the assembly 1.

[0082] It can be understood that there will be some components on the side of the control member 11 facing away from the functional component 12. To prevent the mounting bracket 2 from squeezing the components on this side, the mounting bracket 2 is provided with an avoidance structure 24. The avoidance structure 24 is provided on the first mounting portion 21 and can extend to the connecting portion 23. As Figure 5 shown, the avoidance structure 24 can be an avoidance hole, so as to provide an accommodation space for the components on the control member 11 and reduce the weight of the mounting bracket 2. In this embodiment, when the second positioning hole 212 is provided on the first mounting portion 21, the second positioning hole 212 can be provided only at the position corresponding to the two fixed connecting portions 124 on the first mounting portion 21, that is, the positioning pin 1242 located between the first light-transmitting portion 122 and the second light-transmitting portion 123 can be made shorter so that it only cooperates with the control member 11 for positioning.

[0083] Further, in the extending direction of the first mounting portion 21, the end portion of the first mounting portion 21 extends beyond the end portion of the second mounting portion 22. That is to say, the lengths of the two sides of the U-shaped structure are not equal. After such a setting, it is convenient for the frame to be inserted into the U-shaped groove.

[0084] Wherein, the mounting bracket 2 can be an integrally formed structure. For example, the mounting bracket 2 is formed by bending a sheet metal to form the first mounting portion 21, the second mounting portion 22 and the connecting portion 23. The mounting bracket 2 can also be connected together by welding or screw connection of the first mounting portion 21, the second mounting portion 22 and the connecting portion 23.

[0085] As the carrier of the assembly 1, the mounting bracket 2 needs to have a certain strength and stiffness. Therefore, it is preferred that the mounting bracket 2 is a metal part. Of course, the mounting bracket 2 can also be a plastic part.

[0086] In one embodiment, the frame is provided with a first hole, a second hole and a third hole. When the mounting assembly is mounted on the frame, the switch button 121, the first light-transmitting portion 122 and the second light-transmitting portion 123 on the functional component 1 are respectively located in the first hole, the second hole and the third hole. That is, the switch button 121 is located in the first hole, the first light-transmitting portion 122 is located in the second hole, and the second light-transmitting portion 123 is located in the third hole, so as to minimize the influence of the frame on the light and infrared signals received by the first light-transmitting portion 122 and the second light-transmitting portion 123, and to facilitate the user's operation of the switch button 121.

[0087] It should be noted that the functional component 12 and the assembly 1 of the switch button of the present invention are not limited to being applied to the above-mentioned mounting assembly and electronic device, and can also be applied to other devices or apparatuses.

[0088] Those skilled in the art can easily understand that, on the premise of no conflict, the above-mentioned preferred solutions can be freely combined and superimposed.

[0089] It should be understood that the above embodiments are merely exemplary and not restrictive. Without departing from the basic principle of the present invention, various obvious or equivalent modifications or substitutions made by those skilled in the art to the above details will be included within the scope of the claims of the present invention.
