[0026] Please refer to the following: Figure 1 , Figure 2 , Figure 1 This is an exploded view of the matcher unit in some embodiments of this application. Figure 2 This is a cross-sectional schematic diagram of a matcher unit in some embodiments of this application. For example... Figure 1 , Figure 2 As shown, this application provides a matching unit 10, which includes a motor assembly 100, a capacitor assembly 200, and a frame connecting assembly 300. The motor assembly 100 is used to adjust the capacitance value of the capacitor assembly 200. The frame connecting assembly 300 has a first connecting portion 310 and a second connecting portion 320, and an alignment space 12 is provided between the first connecting portion 310 and the second connecting portion 320. The motor assembly 100 and the capacitor assembly 200 are partially disposed in the alignment space 12 and coaxially connected. The motor assembly 100 is also connected to the frame connecting assembly 300 through the first connecting portion 310, and the capacitor assembly 200 is also connected to the frame connecting assembly 300 through the second connecting portion 320. The first connecting portion 310 and the second connecting portion 320 are parallel and directly opposite each other.

[0027] Therefore, the matching unit 10 described above in this application, by configuring the frame connecting assembly 300, and having an alignment space 12 between the first connecting part 310 and the second connecting part 320 of the frame connecting assembly 300, and connecting the motor assembly 100 to the frame connecting assembly 300 through the first connecting part 310 and the capacitor assembly 200 through the second connecting part 320, and further configuring the first connecting part 310 and the second connecting part 320 to be parallel and facing each other, enables the motor assembly 100 and the capacitor assembly 200 to be partially disposed in the alignment space 12 and coaxially connected, effectively reducing the coaxial error during the assembly of the matching unit 10, enabling faster and more accurate adjustment of the impedance value of the matching unit 10, and ensuring the stability of the matching unit 10 during adjustment.

[0028] The motor assembly 100 and the capacitor assembly 200 are partially disposed in the alignment space 12 and coaxially connected. That is, a portion of the motor assembly 100 and a portion of the capacitor assembly 200 are disposed in the alignment space 12, and the portion of the motor assembly 100 located in the alignment space 12 is coaxially connected to the portion of the capacitor assembly 200 located in the alignment space 12.

[0029] like Figure 1 , Figure 2 As shown, the frame connection assembly 300 includes a first connecting plate 330, a second connecting plate 340, and a support member 350 disposed between the first connecting plate 330 and the second connecting plate 340. The support member 350 is fixedly connected to both the first connecting plate 330 and the second connecting plate 340, and the support member 350 cooperates with the first connecting plate 330 and the second connecting plate 340 to form an alignment space 12. The first connecting plate 330 has a first connecting portion 310, through which the motor assembly 100 is mounted on the first connecting plate 330, and a portion of the motor assembly 100 is located in the alignment space 12. The second connecting plate 340 has a second connecting portion 320, through which the capacitor assembly 200 is mounted on the second connecting plate 340, and a portion of the capacitor assembly 200 is located in the alignment space 12. The first connecting plate 330 and the second connecting plate 340 are parallel and directly opposite each other, and the portions of the motor assembly 100 and the capacitor assembly 200 located in the alignment space 12 are coaxially connected.

[0030] Thus, the matching unit 10 described above in this application forms an alignment space 12 by providing opposing first connecting plates 330 and second connecting plates 340 of the frame connecting assembly 300 and a support member 350 disposed between the first connecting plate 330 and the second connecting plate 340, and the motor assembly 100 and the capacitor assembly 200 are both partially located in the alignment space 12 so as to be coaxially connected in the alignment space 12.

[0031] In some embodiments, the motor assembly 100 may include a connected motor body and a motor connecting shaft. The motor connecting shaft of the motor assembly 100 passes through a first connecting portion 310 and is connected to a first connecting plate 330. The motor body is located on the side of the first connecting plate 330 away from the second connecting plate 340, and the motor connecting shaft is located in the alignment space 12. Correspondingly, the capacitor assembly 200 may include a connected capacitor body and a capacitor connecting shaft. The capacitor connecting shaft of the capacitor assembly 200 passes through a second connecting portion 320 and is connected to a second connecting plate 340. The capacitor body is located on the side of the second connecting plate 340 away from the first connecting plate 330, and the capacitor connecting shaft is located in the alignment space 12. The motor connecting shaft and the capacitor connecting shaft are coaxially connected in the alignment space 12.

[0032] like Figure 1 , Figure 2 As shown, the support member 350 includes a first sub-support member 351350 and a second sub-support member 352350, which are disposed opposite to each other on the edges of the first connecting plate 330 and / or the second connecting plate 340. The space enclosed by the first sub-support member 351350, the second sub-support member 352350, the first connecting plate 330, and the second connecting plate 340 is the alignment space 12.

[0033] Therefore, the matching unit 10 described above in this application, by configuring the first sub-support 351350 and the second sub-support 352350 to be disposed opposite to the edges of the first connecting plate 330 and / or the second connecting plate 340, can increase the stability of the frame connecting assembly 300, and the motor assembly 100 and the capacitor assembly 200 can be more accurately coaxially connected in the alignment space 12.

[0034] like Figure 1 , Figure 2 As shown, the support member 350 also includes a third sub-support member 353350, which is fixedly connected to both the first connecting plate 330 and the second connecting plate 340, and is disposed in the alignment space 12.

[0035] Therefore, the matching unit 10 described above in this application, by configuring the third sub-support 353350 in the alignment space 12, further increases the stability of the frame connection assembly 300 and improves the accuracy of the coaxial connection between the motor assembly 100 and the capacitor assembly 200 in the alignment space 12.

[0036] In some embodiments, the first connecting plate 330 is made of an insulating material, and the second connecting plate 340 is made of a non-insulating material.

[0037] Therefore, the matching unit 10 described above in this application can avoid affecting the capacitor assembly 200 by setting the material of the first connecting plate 330 to an insulating material, and can increase the stability of the frame connecting assembly 300 by setting the material of the second connecting plate 340 to a non-insulating material.

[0038] In some embodiments, the support member 350 is made of a non-insulating material. This increases the stability of the frame connection assembly 300.

[0039] Furthermore, the first connecting plate 330 can be made of plastic, while the second connecting plate 340 and the support member 350 can be made of aluminum.

[0040] like Figure 1 , Figure 2As shown, the second connecting plate 340 includes a main plate 331 and a wing 332 connected together. The second connecting part 320 is disposed on the main plate 331, and the wing 332 is disposed on the edge of the main plate 331 and extends in a direction away from the first connecting plate 330.

[0041] Therefore, the matching unit 10 described above in this application, by setting the wing 332 of the second connecting plate 340, can increase the structural strength of the second connecting plate 340 and facilitate the connection of the matching unit 10 with other functional components.

[0042] Furthermore, the second connecting portion 320 is disposed on the motherboard 331, and the capacitor assembly 200 is mounted on the motherboard 331 through the second connecting portion 320, with a portion of the capacitor assembly 200 located in the alignment space 12. That is, the second connecting plate 340 may specifically include the motherboard 331, the wing 332, and the second connecting portion 320.

[0043] like Figure 1 , Figure 2 As shown, the motor assembly 100 includes a first motor 110 and a second motor 120. The first connecting portion 310 includes a first sub-connecting portion 311 and a second sub-connecting portion 312. The first motor 110 is connected to the first sub-connecting portion 311, and the second motor 120 is connected to the second sub-connecting portion 312. The capacitor assembly 200 correspondingly includes a first capacitor 210 and a second capacitor 220. The second connecting portion 320 includes a third sub-connecting portion 321 and a fourth sub-connecting portion 322. The first capacitor 210 is connected to the third sub-connecting portion 321, and the second capacitor 220 is connected to the fourth sub-connecting portion 322. The first sub-connecting portion 311 and the third sub-connecting portion 321 are parallel and directly opposite each other, and the second sub-connecting portion 312 and the fourth sub-connecting portion 322 are parallel and directly opposite each other.

[0044] Therefore, in the matching unit 10 described above in this application, when the motor assembly 100 includes a first motor 110 and a second motor 120, and the capacitor assembly 200 includes a first capacitor 210 and a second capacitor 220 respectively, the corresponding first connection portion 310 may include a first sub-connection portion 311 and a second sub-connection portion 312, and the second connection portion 320 may also include a third sub-connection portion 321 and a fourth sub-connection portion 322, thereby enabling the coaxial connection of the portions of the first motor 110 and the first capacitor 210 located in the alignment space 12, and the coaxial connection of the portions of the second motor 120 and the second capacitor 220 located in the alignment space 12.

[0045] like Figure 1As shown, the first motor 110 may include a first motor body 111 and a first motor connecting shaft 112 connected together, and the second motor 120 may include a second motor body 121 and a second motor connecting shaft 122 connected together. The first capacitor 210 may include a first capacitor body 211 and a first capacitor connecting shaft 212 connected together, and the second capacitor 220 may include a second capacitor body 221 and a second capacitor connecting shaft 222 connected together.

[0046] like Figure 1 , Figure 2 As shown, the first sub-connecting part 311, the second sub-connecting part 312, the third sub-connecting part 321 and the fourth sub-connecting part 322 are all connecting holes, and the center of the first sub-connecting part 311 corresponds to the center of the third sub-connecting part 321, and the center of the second sub-connecting part 312 corresponds to the center of the fourth sub-connecting part 322.

[0047] Therefore, when the first sub-connection portion 311, the second sub-connection portion 312, the third sub-connection portion 321, and the fourth sub-connection portion 322 are all connection holes, the matching unit 10 described above in this application can achieve partial coaxial connection of the first motor 110 and the first capacitor 210 located in the alignment space 12, and partial coaxial connection of the second motor 120 and the second capacitor 220 located in the alignment space 12, by configuring the center of the first sub-connection portion 311 to correspond to the center of the third sub-connection portion 321, and the center of the second sub-connection portion 312 to correspond to the center of the fourth sub-connection portion 322.

[0048] In some embodiments, the matching unit 10 includes at least one mounting member 13 that connects the first connecting plate 330, the second connecting plate 340, and the support member 350. Each mounting member 13 may be a screw.

[0049] The matching unit 10 of this application, through the above structure and by configuring the frame connection component 300, enables the motor assembly 100 and the capacitor assembly 200 to be partially disposed in the alignment space 12 and coaxially connected, effectively reducing the coaxial error during the assembly of the matching unit 10, enabling faster and more accurate adjustment of the impedance value of the matching unit 10, and ensuring the stability of the matching unit 10 during adjustment.

The frame connecting assembly 300 has a first connecting portion 310 and a second connecting portion 320, with an alignment space 12 between the first connecting portion 310 and the second connecting portion 320. The motor assembly 100 and the capacitor assembly 200 are partially disposed in the alignment space 12 and coaxially connected. The motor assembly 100 is also connected to the frame connecting assembly 300 via the first connecting portion 310, and the capacitor assembly 200 is also connected to the frame connecting assembly 300 via the second connecting portion 320.
