[0049] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0050] Please refer to the following: Figure 1 , Figure 1This is a schematic diagram of the assembly of a button and a housing in the prior art. The button installed on the housing 10 may include: a bracket 01 and a circuit board 02. The first end of the bracket 01 facing the side of the circuit board 02 may have a pressing part 011. The side of the circuit board 02 facing the bracket 01 may have an electronic switch 021. The electronic switch 021 may abut against the pressing part 011.

[0051] The second end of the bracket 01, facing the circuit board 02, may have an elastic portion 012. The end of the elastic portion 012 facing away from the bracket 01 may abut against the housing 10. The middle portion of the bracket 01, facing the circuit board 02, may have a mounting portion 013. The mounting portion 013 may have a mounting hole, and the housing 01 may have a mounting post 11 corresponding to the mounting hole. The mounting post 11 may be located within the mounting hole of the mounting portion 014.

[0052] When the user presses the actuating part 011 to activate the electronic switch 021, the bracket 01 rotates through the cooperation of the mounting post 012 and the mounting hole, thereby compressing the elastic part 012 of the bracket 01 to make it elastic. This allows the elasticity of the elastic part 012 to be released after the user releases the actuating part 011, causing the bracket 01 to rotate and allowing the actuating part 011 of the bracket 01 to return to its initial state.

[0053] However, the tactile feedback of the user pressing the actuating part 011 to activate the electronic switch 021 is related to the assembly effect between the elastic part 012 and the housing 10. Different assembly effects between the elastic part 012 of the bracket 01 and the housing 10 result in different tactile feedback when the user presses the actuating part 011. Thus, after the button is assembled with the housing of different electronic devices, the tactile feedback when the user presses the button on different electronic devices will be different, and the consistency of the user's pressing feel cannot be guaranteed.

[0054] This application provides a button component; please refer to... Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of a button assembly provided in an embodiment of this application. Figure 3 This is a schematic diagram of another button assembly provided in an embodiment of this application. The button assembly includes: a bracket 100, a button body 200, a circuit board 300, and at least two elastic connecting arms 400.

[0055] The bracket 100 in the button assembly may have a first through hole V1, wherein the first through hole V1 may penetrate the bracket 100 in the plate direction.

[0056] The button body 200 in the button assembly can be movably connected to the bracket 100 through the first through hole V1. The button body 200 in the button assembly may include a first button portion 201 distributed on one side of the bracket 100, and a second button portion 202 distributed on the other side of the bracket 100. Here, since the first through hole V1 penetrates the bracket 100 in the plate direction, the button body 200 can move relative to the bracket 100 in the direction perpendicular to the plate direction.

[0057] At least two elastic connecting arms 400 in the button assembly can be fixedly connected at one end to the second button portion 202 in the button body 200, and the other end can be fixedly connected to the bracket 100.

[0058] The circuit board 300 in the button assembly can be connected to one side of the elastic connecting arm 400 of the bracket 100, and the side of the circuit board 300 facing the bracket 100 can have an electronic switch 301, which can abut against the second button part 202 in the button body 200.

[0059] Here, since the second button portion 202 in the button body 200 is in contact with the electronic switch 301, after the user presses the button body 200 so that the button body 200 moves relative to the bracket 100 toward the circuit board 300 in a direction perpendicular to the plate surface of the bracket 100, the second button portion 202 in the button body 200 can activate the electronic switch 301.

[0060] Furthermore, as the button body 200 moves relative to the bracket 100 toward the circuit board 300, the elastic connecting arms 400, which are connected to the button body 200 and the bracket 100 at their respective ends, deform to store a certain amount of elastic force. When the electronic switch 301 is activated and the user stops pressing the button body 200, the elastic connecting arms 400, under the action of the stored elastic force, can move the button body 200 relative to the bracket 100 in a direction away from the circuit board 300 to return to its initial state. This ensures that the user can press the button body 200 again to activate the electronic switch, thus enabling repeated activation of the electronic switch 301 by the button body 200.

[0061] In this application, during the assembly of the button assembly, the button body 200 is simply placed into the first through hole V1, and the end of the elastic connecting arm 400 facing away from the button body 200 is fixedly connected to the bracket 100. This achieves the installation of the button body 200, the elastic connecting arm 400, and the bracket 100. Afterward, the circuit board 300 can be connected to the bracket 100 to complete the overall assembly of the button assembly. Once the button assembly is fully assembled, it can be installed on the housing of the electronic device. Since the button body 200 is connected to the bracket 100 via the elastic connecting arm 400, and the button body 200 rebounds via the elastic connecting arm 400, the assembly effect between the button body 200 and the bracket 100 will not differ. Consequently, the tactile sensation of the user pressing the button body 200 to activate the electronic switch 301 will not differ. Therefore, after the button assembly is installed on the housings of different electronic devices, the tactile sensation of the user pressing the button assembly on different electronic devices is the same, ensuring consistency in the tactile sensation of the button assembly across different electronic devices.

[0062] In summary, this application provides a button assembly, including a bracket, a button body, a circuit board, and a flexible connecting arm. During the assembly of the button assembly, simply insert the button body into the first through hole, and then fix the end of the flexible connecting arm away from the button body to the bracket. This allows for the installation of the button body, the flexible connecting arm, and the bracket. Afterward, the circuit board can be connected to the bracket to complete the overall assembly of the button assembly. Once the button assembly is complete, it can be installed on the housing of an electronic device, facilitating installation. Because the button body is connected to the bracket via the flexible connecting arm, and the button body's rebound is achieved through the flexible connecting arm, the assembly effect between the button body and the bracket will not differ. Consequently, the tactile feedback when the user presses the button body to activate the electronic switch will not differ. Therefore, after the button assembly is installed on the housings of different electronic devices, the tactile feedback when the user presses the button assembly on different electronic devices will be the same, ensuring consistency in the tactile feedback of the button assembly across different electronic devices.

[0063] Optional, such as Figure 4 As shown, Figure 4This is a schematic diagram of a button body and a bracket provided in an embodiment of this application. At least a portion of the elastic connecting arm 400 in the button assembly can be distributed around the second button portion 202 in the button body 200, and can be spaced apart from the second button portion 202. Here, the distribution of at least a portion of the elastic connecting arm 400 around the second button portion 202 in the button body 200 can increase the overall length of the elastic connecting arm 400, thereby increasing the elasticity of the elastic connecting arm 400. In this way, the user can activate the electronic switch by pressing the button body 200 without applying a large force. Moreover, the elasticity of the elastic connecting arm 400 is relatively large. During the process of the button body 200 moving towards the circuit board 300 to activate the electronic switch 301, the elastic connecting arm 400 can store a large amount of elastic force, and thus drive the button body 200 back to the initial state with a large amount of elasticity, so as to ensure that after the user presses the button body 200, the elastic connecting arm 400 can always drive the button body 200 back to the initial state.

[0064] Optional, such as Figure 4 As shown, the elastic connecting arm 400 in the button assembly may include a first connecting segment 401 and a second connecting segment 402. One end of the first connecting segment 401 in the elastic connecting arm 400 may be fixedly connected to the second button portion 202 in the button body 200, and the other end may be fixedly connected to the second connecting segment 402. The end of the second connecting segment 402 in the elastic connecting arm 400 opposite to the first connecting segment 401 may be fixedly connected to the bracket 100.

[0065] The second connecting segment 402 in the elastic connecting arm 400 can be distributed around the second button portion 202 in the button body 200, and can be spaced apart from the second button portion 202. In this way, the second connecting segment 402 is distributed around the second button portion 202, making the length of the second connecting segment 402 relatively long, and thus making the overall length of the elastic connecting arm 400 relatively long.

[0066] Optional, please refer to Figure 4 and Figure 5 , Figure 5 This is a schematic diagram of another connection structure between the button body and the bracket provided in this application embodiment. The bracket 100 in the button assembly may have a mounting post 101 on one side of the elastic connecting arm 400. The end of the second connecting segment 402 in the elastic connecting arm 400 opposite to the first connecting segment 401 may have a first mounting hole S1. At least a portion of the mounting post 101 may be located within the first mounting hole S1 of the second connecting segment 402 and may be fixedly connected to the second connecting segment 402. This achieves a fixed connection between the end of the second connecting segment 402 opposite to the first connecting segment 401 and the bracket 100.

[0067] It should be noted that the button body 200 and the elastic connecting arm 400 in the button assembly can be made of plastic material, so that the button body 200 and the elastic connecting arm 400 themselves have a certain degree of elasticity, which can provide a better pressing feel for the user. For example, the button body 200 and the elastic connecting arm 400 in the button assembly can be made of PC plastic. The bracket 100 in the button assembly can also be made of plastic material; for example, the bracket 100 in the button assembly can be made of PC plastic + ABS plastic. Thus, after the mounting post 101 in the bracket 100 is located within the mounting hole S1 of the second connecting segment 402 in the elastic connecting arm 400, the portion of the second connecting segment 402 surrounding the mounting hole S1 and the mounting post 101 can be heat-fused to achieve a fixed connection between the mounting post 101 and the second connecting segment 402 through heat fusion.

[0068] It should be noted that the number of mounting posts 101 of the bracket 100 can be the same as the number of at least two elastic connecting arms 400, and the end of the second connecting segment 402 of the elastic connecting arm 400 that faces away from the first connecting segment 401 can be fixedly connected to the corresponding mounting post 101. For example, the button assembly in this application may include two elastic connecting arms 400.

[0069] Optional, such as Figure 4 and Figure 5 As shown, the side of the button body 200 may have a positioning rib 203. The bracket 100 may also have a first positioning groove V2 communicating with the first through hole V1, and the first positioning groove V2 of the bracket 100 may penetrate the bracket 100. At least a portion of the positioning ribs 203 in the button body 200 may be located within the first positioning groove V2. In this way, when the button body 200 is placed into the first through hole V1 of the bracket 100, the orientation of the button body 200 can be determined by the positioning ribs 203 and the first positioning groove V2, ensuring that the button body 200 is accurately positioned on the bracket 100.

[0070] It should be noted that the button assembly is generally marked with a positioning rib 203 and the first positioning groove V2 to determine the orientation of the button body 200, so as to ensure that the orientation of the marking on the button assembly is not incorrect.

[0071] Optional, please refer to Figure 6 and Figure 7 , Figure 6 This is a schematic diagram of another button component provided in an embodiment of this application. Figure 7This is a schematic diagram of another button assembly provided in this application embodiment. The bracket 100 may have at least two first latching members 102 on the side facing the circuit board 300. Two of the at least two first latching members 102 in the bracket 100 are arranged along the first direction X, and the two first latching members 102 may be located on opposite sides of the bracket 100 in the first direction X. The first latching members 102 can be latched onto the side of the circuit board 300 away from the bracket 100. In this way, by latching the circuit board 300 with the two first latching members 102, it can be ensured that the circuit board 300 will not move relative to the bracket 100 in the first direction X.

[0072] It should also be noted that the outer edge of the circuit board 300 may have a snap-fit ​​groove S2 corresponding to the first snap-fit ​​member 102. The first snap-fit ​​member 102 can pass through the corresponding snap-fit ​​groove S2 and snap-fit ​​onto the side of the circuit board 300 opposite to the bracket 100. In the first direction X, the length of the position of the circuit board 300 with the snap-fit ​​groove S2 is shorter than that of other positions of the circuit board 300. Thus, after the first snap-fit ​​member 102 of the bracket 100 snaps into the circuit board 300 through the snap-fit ​​groove S2, the size of the connection between the first snap-fit ​​member 102 and the snap-fit ​​groove S2 in the first direction X is small, resulting in a smaller overall size of the button assembly.

[0073] like Figure 6 and Figure 7 As shown, the bracket 100 may also have at least two second latching members 103 on the side facing the circuit board 300. The at least two second latching members 103 in the bracket 100 may be arranged along a first direction X, and the at least two second latching members 103 may be located on the same side of the bracket 100 in a second direction Y. Here, the first direction X may intersect with the second direction Y; for example, the first direction X may intersect perpendicularly with the second direction Y. The outer edge of the circuit board 300 may have at least two limiting grooves S3 corresponding to the at least two second latching members 103. A portion of the second latching members 103 in the bracket 100 may be located within the corresponding limiting groove S3, and the second latching member 103 engages with the side of the circuit board 300 opposite to the bracket 100. That is, the second latching member 103 passes through the limiting groove S3 of the circuit board 300 and engages with the side of the circuit board 300 opposite to the bracket 100.

[0074] It should be noted that after the button assembly is installed on the housing of the electronic device, in the second direction Y, the side of the circuit board 300 opposite to the limiting groove S3 can abut against the inner wall of the housing. In this way, in the second direction Y, the circuit board 300 can be secured by the second snap-fit ​​member 103 of the bracket 100, ensuring that the circuit board 300 will not move relative to the bracket 100 in the second direction Y.

[0075] In this application, as Figure 5As shown, the button assembly may further include a spring block 600, which can be located between the button body 200 and the electronic switch 301 of the circuit board 300. One end of the spring block 600 facing the button body 200 can be fixedly connected to the button body 200, and the other end of the spring block 600 facing the electronic switch 301 can abut against the electronic switch 301. In this way, the button body 200 can abut against the electronic switch 301 through the spring block 600.

[0076] It should be noted that the elastic block 600 can be made of silicone material, and its elasticity can be greater than that of the button body 200. This allows the elastic block 600 to provide a tactile feel when the user presses the electronic switch 301, further enhancing the user's pressing experience. Furthermore, during the process of the user pressing the button body 200 to move it towards the circuit board 300 and activate the electronic switch 301, the elastic block 600 can also store a certain amount of elasticity. Thus, after the user stops pressing the button body 200, it can return to its initial state under the combined action of the elastic block 600 and the elastic connecting arm 400.

[0077] In this application, as Figure 6 and Figure 7 As shown, the bracket 100 may have a positioning post 104 on the side facing the circuit board 300, and the circuit board 300 has a second positioning groove V3 corresponding to the positioning post 104. At least a portion of the positioning post 104 may be located within the second positioning groove V3. Thus, when assembling the circuit board 300 and the bracket 100, the positioning of the circuit board 300 and the bracket 100 can be achieved through the cooperation of the positioning post 104 and the second positioning groove V3. Furthermore, the circuit board 300 can be snapped into place by the second snap-fit ​​member 103 and the first snap-fit ​​member 102, thereby connecting the circuit board 300 and the bracket 100.

[0078] Optional, please refer to Figure 8 , Figure 8 This is an exploded view of a button assembly provided in an embodiment of this application. The circuit board 300 in the button assembly may have a light-emitting element 302 on the side facing the bracket 100. The bracket 100 in the button assembly may have a clearance opening V4 corresponding to the light-emitting element 302. The light emitted by the light-emitting element 302 passes through the clearance opening V4 and then exits.

[0079] It should be noted that after the user presses the button body 200 to activate the electronic switch 301, the electronic switch 301 controls the light-emitting element 302 to emit light. The light emitted by the light-emitting element 302 is visible to the user after passing through the clearance opening V4, thus reminding the user that the electronic switch 301 is on. Similarly, after the user presses the button body 200 to deactivate the electronic switch 301, the electronic switch 301 controls the light-emitting element 302 to stop emitting light, thus reminding the user that the electronic switch 301 is off. In this way, the user can determine whether the electronic switch 301 is on by whether the light-emitting element 302 is emitting light.

[0080] In this application, as Figure 8 As shown, the circuit board 300 may have multiple fourth through holes H1, and the bracket 100 may have multiple fifth through holes H2 corresponding to the multiple fourth through holes H1, with each fourth through hole H1 communicating with its corresponding fifth through hole H2. When the button assembly is assembled and installed onto the housing in the electronic device, screws can pass through the fourth through holes H1 and the fifth through holes H2 and be fixedly connected to the housing.

[0081] Please refer to the following in this application: Figure 9 , Figure 9 This is a schematic diagram of another button body and bracket provided in this application embodiment. The bracket 100 may have multiple reinforcing ribs 700 on the side facing the circuit board 300. The reinforcing ribs 700 can improve the overall strength of the bracket 100. For example, a reinforcing rib 700 may be provided between two adjacent fourth through holes H2 in the bracket 100, and a reinforcing rib 700 may also be provided between the clearance hole V4 and the fourth through hole H2 in the bracket 100. This can prevent the bracket 100 from having low strength due to the presence of multiple through holes.

[0082] In summary, this application provides a button assembly, including a bracket, a button body, a circuit board, and a flexible connecting arm. During the assembly of the button assembly, simply insert the button body into the first through hole, and then fix the end of the flexible connecting arm away from the button body to the bracket. This achieves the installation of the button body, the flexible connecting arm, and the bracket. Afterward, the circuit board can be connected to the bracket to complete the overall assembly of the button assembly. Once the button assembly is complete, it can be installed on the housing of an electronic device. Because the button body is connected to the bracket via the flexible connecting arm, and the button body rebounds via the flexible connecting arm, the assembly effect between the button body and the bracket will not differ. Consequently, the tactile sensation of the user pressing the button body to activate the electronic switch will not differ. Therefore, after the button assembly is installed on the housings of different electronic devices, the tactile sensation of the user pressing the button assembly on different electronic devices is the same, ensuring consistency in the tactile sensation of the button assembly across different electronic devices.

[0083] This application also provides an electronic device, which can be a laser projector, laser TV, desktop computer, or laptop computer, etc.

[0084] Taking electronic devices as projection devices as an example, please refer to... Figure 10 and Figure 11 , Figure 10 This is a schematic diagram of the structure of an electronic device provided in an embodiment of this application. Figure 11 This is a schematic diagram of the structure of another electronic device provided in an embodiment of this application. Figure 12 This is a cross-sectional view of an electronic device provided in an embodiment of this application. The electronic device may include a housing 1100 and a button assembly. The housing 1100 in the electronic device may have a receiving space K and a second through hole A1 penetrating through the receiving space K. The button assembly may be the button assembly in the above embodiment. The button assembly may be installed within the receiving space of the housing 1100, and at least a portion of the first button portion 201 in the button body 200 may be located within the second through hole A1. Thus, after the button assembly is installed on the housing 1100, the user can press the button body 200 through the second through hole A1.

[0085] It should be noted that the electronic device may also include a keycap 1200. The keycap 1200 can be fitted onto the first key portion 201 in the key body 200, and the keycap 1200 can be located within the second through hole A1. Furthermore, the side of the keycap 1200 facing away from the key body 200 can be flush with the surface of the housing 1100 to ensure a more aesthetically pleasing appearance of the housing 1100. In this way, the user can press the key body 200 by pressing the keycap 1200.

[0086] It should be noted that, as Figure 12 , Figure 13 and Figure 14 As shown, Figure 13 This is a schematic diagram of a button assembly according to another embodiment of this application. Figure 14 This is a partial structural diagram of an electronic device provided in an embodiment of this application. The housing 1100 in the electronic device may also have a third through hole A2 communicating with the accommodating space K. The third through hole A2 of the housing 100 may be correspondingly provided with the clearance opening V4 of the bracket 100.

[0087] The electronic device may further include a light guide 1300, a portion of which may be located within the third through hole A2 and the clearance opening V4. The light guide 1300 passes through the third through hole A2 and the clearance opening V4 and abuts against the circuit board 300. The end of the light guide 1300 facing the circuit board 300 may have an opening, and the light-emitting element 302 may be located within the opening of the light guide 1300, allowing the end of the light guide 1300 facing the circuit board 300 to be distributed around the light-emitting element 302. In this way, the light emitted by the light-emitting element 302 can be guided out through the light guide 302, allowing the user to observe whether the light-emitting element 302 is emitting light.

[0088] It should be noted that the side of the light guide 1300 facing away from the circuit board 300 can be flush with the surface of the housing 1100, so that the housing 1100 has a more aesthetically pleasing appearance.

[0089] In this application, as Figure 13 and Figure 14 As shown, the button assembly may further include a light-shielding member 1400. The light-shielding member 1400 may be located on the side of the bracket 100 opposite to the circuit board 300, and may be distributed around the clearance opening V4. The light guide member 1300 in the electronic device may be located within the area enclosed by the light-shielding member 1400. In this way, the light-shielding member 1400 can prevent light emitted from the light-emitting element 302 from entering the receiving space of the housing 100, thus preventing light leakage. It should be noted that the material of the light-shielding member 1400 may be soft foam.

[0090] It should be noted that, as Figure 8 As shown, the bracket 100 may have a positioning line B on the side opposite to the circuit board 300. The positioning line B may be distributed around the avoidance opening V4, and the position of the positioning line B is the position of the light-shielding member 1400. In this way, the installation position of the light-shielding member 1400 on the bracket 100 can be determined by the positioning line B, which facilitates the installation of the light-shielding member 1400.

[0091] In this application, after assembling the button assembly, the light-shielding member 1400 can be first attached to the positioning line B, and the button cap 1200 can be fitted onto the first button portion 201 in the button body 200. Next, before installing the button assembly onto the housing 1100, the light guide member 1300 can be attached to the third through hole A2. Thus, when installing the button assembly with the light-shielding member 1400 and the button cap 1200 onto the housing 1100, the button cap 1200 can be placed into the second through hole A1, while the light guide member 1300 can be placed into the clearance opening V4. This achieves the assembly of the button assembly and the housing of the electronic device.

[0092] It should be noted that, as Figure 14 and Figure 15 As shown, Figure 15 This is a partial structural diagram of another electronic device provided in an embodiment of this application. The first button portion 201 in the button body 200 may have a third snap-fit ​​member 2011. The side wall of the button cap 1200 may have a through groove C. The third snap-fit ​​member 2011 may be located in the through groove C and snap-fit ​​with the button cap 1200 to realize the connection between the button cap 1200 and the button body 200.

[0093] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0094] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
