[0027] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not used to limit the present invention. The term "and / or" used in this specification includes any and all combinations of one or more related listed items.

[0028] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0029] In order to help readers better understand the concept of the present application, the following first describes a partial structure of an electronic device produced using the key assembly device 100 of the present application. Figure 1 and Figure 2 The electronic device includes a housing 200 and a button 300. The housing 200 is provided with a cavity 2002 and a mounting groove 2001 for accommodating an electronic device (not shown). At least a portion of the button 300 is accommodated in the mounting groove 2001, and the button 300 is fixed to the housing 200 by adhesive.

[0030] The existing method for installing the key 300 is: first apply adhesive glue on the mounting groove 2001 of the housing 200, then place the key 300 into the mounting groove 2001, and wait for the adhesive glue to solidify. However, for electronic devices such as headphones, the volume of the mounting groove 2001 on the housing 200 and the volume of the key 300 are both small, which makes it difficult for workers to align the key 300 with the mounting groove 2001. Therefore, the worker needs to spend a lot of time to align the key 300 with the mounting groove 2001, and then put the key 300 into the mounting groove 2001, resulting in low production efficiency and difficulty in ensuring the positional relationship between the key 300 and the mounting groove 2001. In order to solve the above problems, the present application provides a key assembly device 100, which can improve the efficiency of installing the key 300 into the mounting groove 2001 of the housing 200 of the electronic device, thereby improving the production efficiency of the electronic device.

[0031] See also Figure 3 The key assembly device 100 includes a base 1 and a first cover 2. Figure 5 The base 1 is provided with a first mounting portion 11, and the first mounting portion 11 is used to mount a shell 200. When the shell 200 is mounted on the first mounting portion 11, at least a portion of the first mounting portion 11 is accommodated in the cavity 2002 of the shell 200. The first mounting portion 11 imitates the shape of the cavity 2002 of the shell 200, so that when different shells 200 are mounted on the first mounting portion 11, the positions of the different shells 200 relative to the first mounting portion 11 are the same. One end of the first cover body 2 is hinged to the base 1, and the first cover body 2 can rotate relative to the base 1. The first cover body 2 is provided with a first accommodating groove 21, and the first accommodating groove 21 is used to accommodate a part of the button 300, and the shape of the first accommodating groove 21 imitates the shape of the button 300, so that when different buttons 300 are placed in the first accommodating groove 21, the positions of the different buttons 300 relative to the first accommodating groove 21 are the same. Please combine Figure 4 and Figure 6 When the first cover 2 rotates relative to the base 1 to Figure 3, the key 300 arranged in the first receiving groove 21 enters the installation groove 2001 of the housing 200 installed in the first installation part 11. The use process of the key assembly device 100 of the present application is: firstly, the housing 200 is installed in the first installation part 11, and the key 300 is placed in the first receiving groove 21; then, the adhesive is applied to the installation groove 2001 of the housing 200. Finally, the first cover 2 is rotated relative to the base 1 to the first preset position. At this time, the key 300 arranged in the first receiving groove 21 enters the installation groove 2001 of the housing 200 arranged in the first installation part 11, and the assembly of the key 300 is completed. In this embodiment, a first mounting portion 11 is provided on the base 1, one end of the first cover 2 is hinged to the base 1, and a first receiving groove 21 for receiving a part of the key 300 is provided on the first cover 2. When using the key assembly device 100 of the present application, the housing 200 of the electronic device is installed on the first mounting portion 11, and then the adhesive can be applied to the mounting groove 2001 of the housing 200, and then the key 300 is placed in the first receiving groove 21, and then the first cover 2 is rotated relative to the base 1 to Figure 3 The first preset position is shown. At this time, the button 300 enters the installation groove 2001 of the shell 200, and the installation of the button 300 is completed. In this way, there is no need to manually place the button 300 into the installation groove 2001 of the shell 200, which is beneficial to improve the efficiency of installing the button 300 into the shell 200, thereby improving the production efficiency of the electronic device.

[0032] In some embodiments, see Figure 4 The key assembly device 100 also includes an air extraction component 3. Figure 7 The first cover body 2 is provided with a first air extraction channel 22, one end of the first air extraction channel 22 is communicated with the first receiving groove 21, and the air extraction component 3 is communicated with the other end of the first air extraction channel 22 through a pipe 311. The air extraction component 3 is used to extract the air in the first receiving groove 21 and the first air extraction channel 22, so that a negative pressure is formed in the first receiving groove 21. When the button 300 is placed in the first receiving groove 21, under the action of the air extraction component 3, the button 300 can be adsorbed on the first receiving groove 21. When the first cover body 2 is rotated to Figure 3 When the first preset position is shown, the button 300 can be separated from the second receiving groove 81 by stopping the air extraction component 3, so that the button 300 can be installed in the installation groove 2001 of the housing 200. In this embodiment, the air extraction component 3 is set to extract the air in the first receiving groove 21 and the first air extraction channel 22, so that a negative pressure is formed in the first receiving groove 21, so that the button 300 can be adsorbed in the first receiving groove 21, which can reduce the risk of the button 300 falling off during the rotation of the first cover 2.

[0033] In some embodiments, see Figure 4 and Figure 5 The air extraction component 3 includes a first air extraction member 31 and a first switch 32. The first air extraction member 31 is connected to the first air extraction channel 22 through a pipe 311. The first air extraction member 31 is used to extract air from the first air extraction channel 22 and the first receiving groove 21 to form a negative pressure in the first receiving groove 21. The first switch 32 is arranged on the base 1. The first switch 32 is electrically connected to the first air extraction member 31. The first switch 32 is used to control the operation of the air extraction component 3. When the first switch 32 is turned on, the first air extraction member 31 is in a working state. At this time, a negative pressure is formed in the first receiving groove 21, and the button 300 can be adsorbed to the first receiving groove 21; when the first switch 32 is turned off, the first air extraction member 31 stops working. At this time, the negative pressure in the first receiving groove 21 disappears, and the first air extraction member 31 cancels the adsorption of the button 300. Therefore, when the button 300 is placed in the first receiving groove 21, the first switch 32 can be turned on; when the first cover body 2 is rotated to Figure 3 When the first preset position is reached, the first switch 32 can be disconnected to eliminate the negative pressure in the first receiving groove 21. Figure 6 , the button 300 can be installed in the installation groove 2001 of the shell 200.

[0034] In some embodiments, see Figure 4 The first switch 32 is a trigger switch. The first cover 2 is provided with a first trigger member 23. When the first cover 2 is rotated to Figure 3 When the first preset position is shown, the first trigger 23 triggers the first switch 32 to disconnect, so that the first air extraction member 31 stops working, and the button 300 can be installed in the installation groove 2001 of the housing 200; when the first cover 2 leaves the first preset position, the first trigger 23 gradually moves away from the first switch 32, at this time, the first switch 32 is turned on, and the first air extraction component 3 is in working state. In this embodiment, the first switch 32 is controlled by the first trigger 23. When the first cover 2 is in the first preset position, the first trigger 23 triggers the first switch 32 to disconnect, so that the first air extraction member 31 cancels the adsorption of the button 300, and the button 300 can be installed in the installation groove 2001; when the first cover 2 is in other positions, the first switch 32 is turned on, so that the first air extraction member 31 can adsorb the button 300 located in the first receiving groove 21, and there is no need to manually control the conduction or disconnection of the first switch 32, which is convenient to operate.

[0035] Furthermore, the first switch 32 is a magnetic trigger switch, and the first trigger element 23 is a magnetic trigger element.

[0036] In some embodiments, see Figure 4The first cover 2 is provided with a first magnetic member 24, and the key assembly device 100 includes a second magnetic member 4. At least a portion of the first magnetic member 24 is embedded in the base 1. When the first cover 2 is rotated to Figure 3 When the first preset position is shown, the first magnetic member 24 attracts the second magnetic member 4. In this embodiment, the first cover 2 can be kept in the first preset position by the attraction between the first magnetic member 24 and the second magnetic member 4, and when the key 300 is installed in the mounting groove 2001 of the housing 200, the first cover 2 can provide pressure to press the key 300 into the mounting groove 2001, thereby improving the connection strength between the key 300 and the mounting groove 2001.

[0037] In some embodiments, see Figure 3 The base 1 is provided with a first protrusion 12 and a second protrusion 13, the first protrusion 12 and the second protrusion 13 are spaced apart along the first direction X, a portion of the first cover 2 is located between the first protrusion 12 and the second protrusion 13, the key assembly device 100 includes a rotation axis 5, the rotation axis 5 passes through the first protrusion 12, a portion of the first cover 2 and the second protrusion 13 in sequence along the first direction X, and the rotation axis 5 can rotate relative to the first protrusion 12 and the second protrusion 13, therefore, the first cover 2 can rotate relative to the base 1 around the rotation axis 5. Wherein, please combine Figure 4 , the first magnetic member 24 and the first trigger member 23 are both arranged on the side of the first cover 2 away from the rotation axis 5. In this embodiment, the first cover 2 can be rotated relative to the first protrusion 12 and the second protrusion 13 by the rotation axis 5, and the first trigger member 23 is arranged on the side of the first cover 2 away from the rotation axis 5, so that when the first cover 2 is in the first preset position relative to the base 1, the distance between the first trigger member 23 and the first switch 32 is the shortest. At this time, the first trigger member 23 triggers the first switch 32 to disconnect, so that the first suction member 31 stops working, the negative pressure in the first receiving groove 21 disappears, and the button 300 arranged in the first receiving groove 21 is inserted into the installation groove 2001 of the shell 200 arranged in the first installation part 11, and between the first magnetic member 24 and the second magnetic member Under the attraction of the sexual member 4, the first cover body 2 can press the button 300 into the mounting groove 2001 of the shell 200, so that the button 300 and the inner wall of the mounting groove 2001 are more firmly bonded; and when the first cover body 2 rotates away from the first preset position, the first trigger member 23 gradually moves away from the first switch 32, so that the first switch 32 is turned on, and the first vacuum member 31 resumes working. At this time, when the button 300 is placed in the first accommodating groove 21, a negative pressure is formed in the first accommodating groove 21, thereby adsorbing the button 300 to the first accommodating groove 21, reducing the risk of the button 300 falling off from the first accommodating groove 21 before the button 300 is inserted into the mounting groove 2001.

[0038] In some embodiments, see Figure 5The key assembly device 100 includes a first rotating sleeve 6 and a second rotating sleeve 7, and the first rotating sleeve 6 and the second rotating sleeve 7 are both sleeved on the rotating shaft 5. The first protrusion 12 is provided with a first rotating hole 121, and the first rotating sleeve 6 is at least partially inserted into the first rotating hole 121. The second protrusion 13 is provided with a second rotating hole 131, and the second rotating sleeve 7 is at least partially inserted into the second rotating hole 131. In this embodiment, by providing the first rotating sleeve 6 and the second rotating sleeve 7, the first cover body 2 can be rotated more smoothly relative to the first protrusion 12 and the second protrusion 13, which is conducive to reducing the wear on the rotating shaft 5.

[0039] In some embodiments, see Figure 5 The base 1 is provided with a second mounting portion 14, and the second mounting portion 14 is used to mount the housing 200. Figure 4 When the shell 200 is installed on the second mounting portion 14, at least a portion of the second mounting portion 14 is accommodated in the cavity 2002 of the shell 200. The second mounting portion 14 imitates the shape of the cavity 2002 of the shell 200, so that when different shells 200 are installed on the second mounting portion 14, the positions of different shells 200 relative to the second mounting portion 14 are the same. The key assembly device 100 also includes a second cover body 8, one end of the second cover body 8 is hinged to the base 1, and the second cover body 8 can rotate relative to the base 1. The second cover body 8 is provided with a second accommodating groove 81, and the second accommodating groove 81 is used to accommodate a part of the key 300, and the shape of the second accommodating groove 81 imitates the shape of the key 300, so that when different keys 300 are placed in the second accommodating groove 81, the positions of different keys 300 relative to the second accommodating groove 81 are the same. When the second cover body 8 is rotated relative to the base 1 to Figure 3 When the second preset position is shown, the key 300 arranged in the second receiving groove 81 enters the mounting groove 2001 of the shell 200 installed in the second mounting portion 14. The use process of the second cover 8 and the second mounting portion 14 in the key assembly device 100 of the present application is: firstly, the shell 200 is installed on the second mounting portion 14, and the key 300 is placed at the second receiving groove 81; then, the adhesive is applied to the mounting groove 2001 of the shell 200. Finally, the second cover 8 is rotated relative to the base 1 to the second preset position. At this time, the key 300 arranged in the second receiving groove 81 enters the mounting groove 2001 of the shell 200 arranged in the second mounting portion 14, and the assembly of the key 300 is completed. In this embodiment, by setting the second mounting portion 14 and the second cover 8, the key assembly device 100 can simultaneously install two keys 300 in two shells 200 respectively, which is conducive to improving production efficiency.

[0040] In some embodiments, see Figure 7The second cover 8 is provided with a second air extraction channel 82, one end of which is connected to the second receiving groove 81. Figure 4 The air extraction component 3 includes a second air extraction member 33 and a second switch 34, the second air extraction member 33 and the second switch 34 are electrically connected, the second air extraction member 33 is connected to the second air extraction channel 82 through a pipe 331, and the second air extraction member 33 is electrically connected to the trigger switch. The second air extraction member 33 is used to extract air from the second receiving groove 81 and the second air extraction channel 82, so that when the button 300 is set in the second receiving groove 81, a negative pressure is formed in the second receiving groove 81 to adsorb the button 300. The second cover body 8 is provided with a second trigger member 83. When the second cover body 8 is rotated to Figure 3 When the second preset position is shown, the second trigger member 83 triggers the second switch 34 to disconnect, and the second air extraction member 33 stops working. At this time, the button 300 set in the second receiving groove 81 is inserted into the mounting groove 2001 of the shell 200 set on the second mounting portion 14; when the second cover 8 leaves the second preset position, the second trigger member 83 gradually moves away from the second switch 34, the second switch 34 is turned on, and the second air extraction member 33 is in a working state. At this time, when other buttons 300 are placed in the second receiving groove 81, the second air extraction member 33 can absorb the button 300 to the second receiving groove 81. In this embodiment, by setting the second air extraction member 33 to extract the air in the second receiving groove 81 and the second air extraction channel 82, a negative pressure is formed in the second receiving groove 81, so that the button 300 can be absorbed in the second receiving groove 81, which can reduce the risk of the button 300 falling off during the rotation of the second cover 8.

[0041] In some embodiments, the second switch 34 is a magnetic trigger switch, and the second trigger member 83 is a magnetic trigger member.

[0042] In some embodiments, see Figure 4 , the second cover 8 is provided with a third magnetic member 84, and the key assembly device 100 further includes a fourth magnetic member 9, which is provided on the base 1.

In this embodiment, the second cover 8 can be kept in the second preset position by the attraction between the third magnetic member 84 and the fourth magnetic member 9, and when the key 300 is installed in the installation groove 2001 of the housing 200, the second cover 8 can provide pressure to press the key 300 into the installation groove 2001, thereby improving the connection strength between the key 300 and the installation groove 2001 when the key 300 is installed in the installation groove 2001.

[0043] In some embodiments, see Figure 4 and Figure 5The base 1 is provided with a third protrusion 15. Along the first direction X, the first protrusion 12, the second protrusion 13 and the third protrusion 15 are distributed at intervals. The third protrusion 15 is provided with a third rotating hole 151. The key assembly device 100 includes a third rotating sleeve 10. The third rotating sleeve 10 is sleeved on the rotating shaft 5. The third rotating sleeve 10 is inserted into the third rotating hole 151. A portion of the second cover body 8 is provided between the second protrusion 13 and the third protrusion 15.
