DETAILED DESCRIPTION

[0014] In order to make the purpose, technical solutions and advantages of this application more clearly understood, the present application is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0015] Please refer to Figure 1 An embodiment of the present application provides an electronic device 1, including a housing 2 and internal components arranged in the housing 2.

[0016] The housing 2 can support and protect the internal components disposed therein. The housing 2 can be made of plastic or metal. Specifically, the housing 2 can be made of plastic to insulate the housing 2, thereby reducing the risk of electric shock to the user. Furthermore, since the plastic material is lightweight, the housing 2 is lightweight, thereby reducing the overall weight of the electronic device 1, making it easier for the user to carry and use the electronic device 1. Specifically, the housing 2 can be integrally injection molded to provide the housing 2 with a high structural strength, thereby making the housing 2 less susceptible to damage and protecting the internal components within the housing 2, thereby reducing the probability of damage to the internal components, thereby allowing the electronic device 1 to have a longer service life.

[0017] For example, the electronic device 1 can be at least one of a charging device, an energy storage device, a headset, an electric toothbrush, and a sweeping robot. In other embodiments, the electronic device 1 can also be in other forms. In the embodiments of the present application, the specific form of the electronic device 1 is not limited.

[0018] Illustratively, the internal element may include at least one of an electronic component and a structural member. The electronic component may be disposed on a circuit board or electrically connected to the circuit board.

[0019] Please refer to Figure 1 and Figure 2 In one embodiment, the housing 2 includes a shell 21 and a key structure 3. The shell 21 has a key hole 21A.

[0020] Specifically, the key structure 3 includes a light-emitting component 32 , a key 33 , a soft plastic component 34 and a key cap 35 .

[0021] The light-emitting element 32 can be disposed on the circuit board 31 and controlled by the circuit board 31 to emit light. For example, the light-emitting element 32 can be at least one of a lamp bead, a light bar, or a display screen. In the embodiment of the present application, the specific form of the light-emitting element 32 is not limited. It is understood that the key structure 3 can also include multiple light-emitting elements 32, and the multiple light-emitting elements 32 can form a corresponding pattern. In the embodiment of the present application, there is no specific limitation on the number and arrangement of the light-emitting elements 32.

[0022] The button 33 can also be provided on the circuit board 31, and is used to trigger the button 33, so that the circuit board 31 receives the corresponding trigger signal and can respond to the corresponding action. It is understood that the light-emitting element 32 and the button 33 can be provided on the same circuit board or on two separate circuit boards. In the embodiment of the present application, this is not specifically limited.

[0023] The soft plastic member 34 includes a pressing portion 341 having a pressing area 34A and a light-guiding area 34B. The light-guiding area 34B partially overlaps the pressing area 34A. The pressing area 34A corresponds to the key 33. When the pressing area 34A moves toward the key 33 and abuts against the key 33, the key 33 can send a corresponding trigger signal to the circuit board 31, causing the circuit board 31 to respond to the corresponding action. The light-guiding area 34B corresponds to the light-emitting element 32 and guides the light emitted by the light-emitting element 32. Exemplarily, the material of the soft plastic member 34 includes, but is not limited to, at least one of silicone, rubber, thermoplastic polyurethane (TPU), thermoplastic elastomer (TPE), soft polyvinyl chloride (PVC), and polyurethane (PU). In other embodiments, the soft plastic member 34 can also be made of other materials. It is understandable that, in order to reduce light crosstalk in the light guiding area 34B, all areas of the soft plastic member 34 except the light guiding area 34B may be opaque.

[0024] The keycap 35 is connected to the pressing portion 341 and has a display area 35A. The light emitted by the light-emitting component 32 can be emitted through the light-guiding area 34B and the display area 35A, thereby lighting up the display area 35A to indicate the function of the key 33; the keycap 35 is partially protruded from the key hole 21A, so that the user can press the keycap 35 through the key hole 21A, thereby causing the soft rubber component 34 to move toward the direction close to the key 33 to trigger the key 33, and then the circuit board 31 obtains the trigger signal to respond to the corresponding operation.

[0025] In an embodiment of the present application, the light-guiding area 34B is arranged on the pressing portion 341 so that the keycap 35 integrates the display function, making the key structure 3 compact in design and reducing the overall volume of the key structure 3, thereby reducing the space occupied by the key structure 3 in the shell 2, thereby reducing the volume of the shell 2, and thus making the electronic device 1 smaller in size, in line with the development trend of miniaturization of the electronic device 1.

[0026] Please refer to Figure 2 and Figure 3In one embodiment, the soft rubber member 34 further includes a connecting portion 342, which is disposed around the pressing portion 341. The pressing portion 341 is protruded from the connecting portion 342, and the pressing portion 341 is protruded from the key hole 21A. When the user presses the pressing portion 341, the pressing portion 341 can generate elastic deformation in a direction closer to the key 33, thereby triggering the key 33. When the pressing portion 341 is released, the pressing portion 341 can push the keycap 35 in a direction away from the key 33. Compared to the pressing portion 341 being flush with the connecting portion 342, the pressing portion 341 of the present application is protruded from the connecting portion 342, which can make the pressing portion 341 have a stronger elastic deformation ability, thereby improving the rebound performance of the pressing portion 341, making it easier for the user to press the keycap 35 next time, thereby improving the user experience.

[0027] Please refer to Figures 2 to 4 In one embodiment, a receiving groove 341A is formed on the side of the pressing portion 341 facing away from the keycap 35. The soft rubber component 34 also includes a pressing protrusion 343 and a light guiding portion 344. The pressing protrusion 343 is connected to the bottom of the receiving groove 341A and is arranged in the pressing area 34A. The pressing protrusion 343 is arranged corresponding to the key 33 and is used to press the key 33; the light guiding portion 344 is connected to the pressing portion 341 and is arranged in the light guiding area 34B. The light guiding portion 344 is arranged corresponding to the light-emitting component 32 and is used to guide the light emitted by the light-emitting component 32 to the display area 35A, thereby lighting up the display area 35A.

[0028] It can be understood that the soft rubber part 34 can also include multiple light-guiding parts 344, and the multiple light-guiding parts 344 are all arranged in the light-guiding area 34B. The multiple light-guiding parts 344 are arranged one-to-one corresponding to the multiple light-emitting parts 32, and are used to guide the light emitted by the corresponding light-emitting parts 32 to the display area 35A, thereby lighting up the display area 35A.

[0029] It is understood that the spacing between adjacent light guide portions 344 can reduce the probability of optical crosstalk between the two adjacent light guide portions 344. It is also understood that due to the spacing between the two adjacent light guide portions 344, the soft plastic member 34 can also be made of a fully transparent or semi-transparent material. In the embodiments of the present application, this is not limited to this.

[0030] Please refer to Figure 3 and Figure 4In one embodiment, the display area 35A on the keycap 35 is at least one of a transparent portion or a light-transmitting hole 35B, and is arranged corresponding to the light-guiding portion 344, so that the light emitted by the light-emitting component 32 can enter the display area 35A through the light-guiding portion 344 and be emitted through the transparent portion or the light-transmitting hole 35B to illuminate the display area 35A. Exemplarily, the display area 35A can be at least one of an indication pattern, an indication Chinese character, or an indication English formed by the transparent portion. Of course, the light-transmitting hole 35B can also be surrounded by an indication pattern, an indication Chinese character, or an indication English. In the embodiment of the present application, there is no limitation on the form of the display area 35A.

[0031] Please refer to Figure 3 and Figure 4 Specifically, the display area 35A on the keycap 35 includes a plurality of light-transmitting holes 35B, and adjacent two light-transmitting holes 35B are arranged at intervals. Each light-guiding portion 344 includes a first light-guiding sub-portion 3441 and a second light-guiding sub-portion 3442. The first light-guiding sub-portion 3441 and the second light-guiding sub-portion 3442 are both connected to the pressing portion 341. An end of the first light-guiding sub-portion 3441 away from the pressing portion 341 extends toward a side close to the light-emitting component 32 and is arranged corresponding to the light-emitting component 32. An end of the second light-guiding sub-portion 3442 away from the pressing portion 341 is passed through the corresponding light-transmitting hole 35B. The light emitted by the light-emitting component 32 is emitted through the first light-guiding sub-portion 3441, the second light-guiding sub-portion 3442 and the light-transmitting hole 35B to illuminate the display area 35A.

[0032] Please refer to Figure 3 and Figure 4 It can be understood that since the end of the second light guide portion 3442 away from the pressing portion 341 is passed through the light-transmitting hole 35B of the keycap 35, the keycap 35 can be used to block the light crosstalk between two adjacent light-transmitting holes 35B to improve the lighting accuracy of the display area 35A.

[0033] Please refer to Figures 1 to 4 In one embodiment, the key structure 3 further includes a support member 36 connected to the side of the connecting portion 342 facing away from the pressing portion 341. The support member 36 supports the soft plastic member 34, ensuring that the pressing protrusion 343 can trigger the key 33 when the user presses the keycap 35. This also ensures that the light guide 344 can guide the light emitted by the light-emitting element 32 to the display area 35A, thereby illuminating the display area 35A. For example, the support member 36 can be made of metal or hard plastic to provide support for the soft plastic member 34.

[0034] Please refer to Figure 3 and Figure 4Furthermore, the support member 36 has a first avoidance hole 36A and a second avoidance hole 36B. The first avoidance hole 36A and the second avoidance hole 36B are spaced apart, and the first avoidance hole 36A is provided corresponding to the key 33. The pressing protrusion 343 extends toward the key 33 and passes through the first avoidance hole 36A to abut against the key 33, thereby improving the accuracy of the user pressing the keycap 35 to trigger the key 33. The second avoidance hole 36B is provided corresponding to the light-emitting member 32. The end of the light-guiding portion 344 closest to the light-emitting member 32 is located in the second avoidance hole 36B, so that the light-guiding portion 344 can receive light emitted by the light-emitting member 32 and illuminate the display area 35A.

[0035] It can be understood that the support member 36 can have multiple second avoidance holes 36B, and two adjacent second avoidance holes 36B are arranged at intervals. The multiple second avoidance holes 36B are arranged corresponding to the multiple light-emitting members 32. The end of each light-guiding portion 344 close to the light-emitting member 32 is located in the corresponding second avoidance hole 36B. The support member 36 can be used to block the light crosstalk between two adjacent light-emitting members 32 to improve the lighting accuracy of the display area 35A.

[0036] Please refer to Figures 1 to 4 In one embodiment, the key structure 3 further includes a light shielding member 37, which has a through hole 37A. The through hole 37A is arranged in a one-to-one correspondence with the light-emitting member 32, and the two surfaces of the light shielding member 37 penetrated by the through hole 37A are respectively connected to the support member 36 and the circuit board 31, thereby reducing the probability of light overflow from the light-emitting member 32, thereby reducing the brightness of the light received by the light guide portion 344, and further increasing the brightness of the display area 35A, thereby improving the recognition of the display area 35A, and facilitating the user to identify the display area 35A.

[0037] It can be understood that the shading member 37 can have multiple through holes 37A, and the multiple through holes 37A are arranged in a one-to-one correspondence with the multiple light-emitting members 32. The two surfaces of the light-shielding member 37 penetrated by the through holes 37A are respectively connected to the support member 36 and the circuit board 31, so that the light-shielding member 37 can be used to block the end of the light-guiding portion 344 close to the light-emitting member 32, further reducing the probability of light crosstalk between the two adjacent light-guiding portions 344, so as to improve the lighting accuracy of the display area 35A.

[0038] Please refer to Figure 3In one embodiment, the support member 36 has a mounting groove 36C on the side facing the soft plastic member 34. The connecting portion 342 is embedded in the mounting groove 36C to increase the contact area between the connecting portion 342 and the support member 36, thereby improving the connection stability between the connecting portion 342 and the support member 36. The mounting groove 36C also positions the connecting portion 342 to improve the installation accuracy of the soft plastic member 34, thereby reducing the possibility of misalignment between the pressing protrusion 343 and the key 33, and between the light guide portion 344 and the light-emitting element 32. Consequently, when the user presses the keycap 35, the pressing protrusion 343 can trigger the key 33, ensuring that the display area 35A is accurately illuminated.

[0039] Please refer to Figure 3 and Figure 4 Furthermore, the support member 36 has a first positioning portion 361, and the soft rubber member 34 has a second positioning portion 345. The first positioning portion 361 and the second positioning portion 345 are positioned and matched to make the support member 36 and the soft rubber member 34 matched and connected; wherein, one of the first positioning portion 361 and the second positioning portion 345 is a positioning column, and the other of the first positioning portion 361 and the second positioning portion 345 is a positioning hole, and the positioning column is inserted into the positioning hole. By utilizing the cooperation of the first positioning portion 361 and the second positioning portion 345, the support member 36 and the soft rubber member 34 are matched and connected, which can further improve the installation accuracy of the soft rubber member 34 and the support member 36.

[0040] Exemplarily, the support member 36 may have a plurality of first positioning portions 361, and the soft rubber member 34 may have a plurality of second positioning portions 345, and the second positioning portions 345 are arranged in a one-to-one correspondence with the first positioning portions 361, thereby further increasing the contact area between the support member 36 and the soft rubber member 34 to improve the connection stability between the support member 36 and the soft rubber member 34.

[0041] Specifically, the support member 36 can be provided with two first positioning portions 361, which are spaced apart. The two first positioning portions 361 cooperate with the two second positioning portions 345 to prevent errors in the installation of the soft plastic member 34 and the support member 36, thereby improving the installation efficiency of the soft plastic member 34 and the support member 36. It is understood that the number of first positioning portions 361 and second positioning portions 345 can be other numbers, and the first positioning portions 361 and second positioning portions 345 can be arranged in other ways. In the embodiments of the present application, there is no specific limitation on the number and arrangement of the first positioning portions 361 and second positioning portions 345.

[0042] Please refer to Figure 3 and Figure 4In one embodiment, the keycap 35 has a third positioning portion 351, and the soft plastic member 34 has a fourth positioning portion 346. The third positioning portion 351 and the fourth positioning portion 346 are positioned and matched. One of the third positioning portion 351 and the fourth positioning portion 346 is a positioning post, and the other of the third positioning portion 351 and the fourth positioning portion 346 is a positioning hole. The positioning post is inserted into the positioning hole. The third positioning portion 351 and the fourth positioning portion 346 cooperate to ensure the keycap 35 is connected to the soft plastic member 34, thereby improving the positioning accuracy of the keycap 35 and the soft plastic member 34.

[0043] Exemplarily, the keycap 35 can have multiple third positioning portions 351, and the soft plastic part 34 can have multiple fourth positioning portions 346. The third positioning portions 351 and the fourth positioning portions 346 are arranged in a one-to-one correspondence, thereby further increasing the contact area between the keycap 35 and the soft plastic part 34 to improve the connection stability between the keycap 35 and the soft plastic part 34.

[0044] Specifically, the keycap 35 can be provided with three third positioning portions 351, and the three third positioning portions 351 can be respectively provided at the three vertices of the triangle, so that the three third positioning portions 351 cooperate with the three fourth positioning portions 346 to improve the installation accuracy between the keycap 35 and the soft plastic member 34, thereby improving the installation efficiency between the keycap 35 and the soft plastic member 34. It is understandable that the third positioning portions 351 and the fourth positioning portions 346 can also be other numbers, and the third positioning portions 351 and the fourth positioning portions 346 can also be arranged in other ways. In the embodiment of the present application, there is no specific limitation on the number and arrangement of the third positioning portions 351 and the fourth positioning portions 346.

[0045] Please refer to Figure 2 To enhance the tightness of the installation between the soft plastic member 34 and the housing 21, the inner wall of the housing 21 has a first mating portion 211. The soft plastic member 34 also includes a second mating portion 347, which is disposed on the connecting portion 342 and connected to the first mating portion 211. One of the first mating portion 211 and the second mating portion 347 is a protrusion, and the other is a groove. When the soft plastic member 34 is attached to the inner wall of the housing 21, the support member 36 compresses the soft plastic member 34, causing it to deform and connect the first mating portion 211 and the second mating portion 347. This ensures a tight connection between the soft plastic member 34 and the housing 21, reducing the probability of liquid entering the electronic device 1 through the gap between the soft plastic member 34 and the housing 21, thereby reducing the probability of internal components corroding and extending the service life of the electronic device 1.
