[0027] Figures 1 to 3 The different components and different states of the compressor of the present application are shown, and an embodiment of the controller of the present application is shown in a centralized manner. The controller 10 may include: a first housing 100, a second housing 200, a circuit board 300, and the like.
[0028] The first shell 100 and the second shell 200 may have outer contours that match each other and jointly surround the first cavity 101 located therebetween. In other words, the first shell 100 and the second shell 200 match each other in shape. Figure 3 In the illustrated embodiment, the first housing 100 and the second housing 200 are connected together by a series of bolts or screws 400. Therefore, the first housing 100 and the second housing 200 may include a series of bolt holes along their outer contours, and the bolt holes on the first housing 100 and the second housing 200 correspond to each other.
[0029] The circuit board 300 can be accommodated in the first cavity 101 between the first housing 100 and the second housing 200. In the illustrated embodiment, the first housing 100 and the second housing 200 respectively include one or more first protrusions 110 and one or more second protrusions 210. The first protrusions 110 and the second protrusions 210 can be protrusions toward the inside of the first cavity 101. In one embodiment, the first protrusions 110 and the second protrusions 210 can extend vertically relative to other parts of the first housing 100 and the second housing 200. It is easy to understand that each first protrusion 110 and the second protrusion 210 can correspond to each other one by one and be aligned with each other. The first protrusions 110 and the second protrusions 210 can be distributed within the first cavity 101, for example, distributed along the contour edge of the circuit board 300. In some embodiments, some of the first protrusions 110 and the second protrusions 210 can be distributed inside the contour of the circuit board 300. In addition, various electronic devices can be arranged on the circuit board 300.
[0030] The first protrusion 110 and the second protrusion 210 may cooperate to position the circuit board 300. For example, the first protrusion 110 and the second protrusion 210 may clamp the circuit board 300 in place.
[0031] In one embodiment, the first protrusion 110 and the first housing 100 may be integrally formed, and the second protrusion 210 and the second housing 200 may be integrally formed. In one embodiment, the first housing 100 and the second housing 200 may be made of an aluminum alloy material.
[0032] The first protrusion 110 and the second protrusion 210 may include a matching structure. Specifically, the plurality of first protrusions 110 and the plurality of second protrusions 210 are arranged one by one, and at least two of the plurality of first protrusions 110 and at least two of the plurality of second protrusions 210 may include a matching structure. In one embodiment, the matching structure may be a recess and a pin. In one embodiment, the matching structure may be mutually adapted. In one embodiment, the size of the recess may be larger than the size of the pin.
[0033] The first protrusion 110 and the second protrusion 210 may include a recess at the end thereof, and the other of the first protrusion 110 and the second protrusion 210 may include a pin at the end thereof. Correspondingly, the circuit board 300 may include a through hole 310 at a position corresponding to the recess and the pin. The size of the through hole 310 may be configured so that the pin can pass through it. Therefore, the pin can extend through the through hole 310 and further reach the inside of the recess. The pin may be configured in size to fit the inner wall of the through hole 310 and the inner wall of the recess. In one embodiment, the pin may be configured in size to be smaller than the size of the through hole 310, and the end of the pin fits the inner wall of at least a portion of the recess.
[0034] The pin and the recess may have various profile shapes. For example, the inner profile of the recess may have one of the following shapes: a cone, a cylinder, a frustum, a prism, a pyramid, or a combination thereof. Similarly, the outer profile of the pin may have one of the following shapes: a cone, a cylinder, a frustum, a prism, a pyramid, or a combination thereof. In one embodiment, the pin may be generally cylindrical, and its end may be formed as a portion of a sphere. In one embodiment, the pin may be segmented. For example, the pin may include a first section and a second section, the first section may be adapted to the through hole 310, and the second section may be adapted to the recess. In one embodiment, the outer profile of the pin and the inner profile of the recess may be configured to be smooth.
[0035] Figures 4 to 7 The fixing method of the circuit board of the present application is schematically shown by cross section. Figures 4 to 7 As shown, the first housing 100 is a housing located at the upper part, and the second housing 200 is a housing located at the lower part. The first protrusion 110 extends integrally from the first housing 100, and the second protrusion 210 extends integrally from the second housing 200. The first protrusion 110 and the second protrusion 210 are aligned in the vertical direction. The circuit board 300 is positioned between the first protrusion 110 and the second protrusion 210, and the circuit board 300 includes a through hole 310. In addition, Figures 4 to 7 A first cavity 101 is shown. The first cavity 101 may be positioned between the first housing 100 and the second housing 200.
[0036] exist Figure 4 In the illustrated embodiment, the end of the first protrusion 110 may be flat and may not include any protrusions or similar structures. The first protrusion 110 and the second protrusion 210 may cooperate to clamp the circuit board 300 so that the circuit board 300 is fixed in place. For example, the ends of the first protrusion 110 and the second protrusion 210 may fit on both sides of the circuit board 300.
[0037] exist Figures 5 to 7In the illustrated embodiment, the end of the first protrusion 110 may include a pin 111, and the pin 111 may extend vertically from the end of the first protrusion 110. Figure 5 As shown, the size of the pin 111 is smaller than the size of the through hole 310, and the size of the pin 111 is configured to match the size of the recess 211. Therefore, the first protrusion 110 and the second protrusion 210 can cooperate to clamp the circuit board 300, and the pin 111 and the recess 211 can cooperate to position the circuit board 300 so that the circuit board 300 is fixed in place. For example, the ends of the first protrusion 110 and the second protrusion 210 can fit on both sides of the circuit board 300. Figure 6 and Figure 7 As shown, the pin 111 may be a portion of a circle or a tapered shape, and a portion of the pin 111 may extend into the through hole 310 but not into the recess 211. In other words, the pin 111 may at least partially extend into the through hole 310.
[0038] In one embodiment, the end of the pin 111 may be configured to be tapered. For example, Figures 5 to 7 The end of the pin 111 shown has a spherical or truncated cone profile, thereby facilitating the installation of the pin 111 . Figures 5 to 7 The matching structures shown can have at least two groups, or at least three groups in the entire controller. In one embodiment, at least two groups of matching structures in the controller are used. Figures 5 to 7 , and other matching structures use Figure 4 The structure in . Figures 4 to 7 The matching structures shown may be distributed throughout the entire outline of the circuit board 300 , for example, dispersedly distributed, so as to provide positioning for the circuit board 300 .
[0039] It is easy to understand that in some embodiments, the ends of the first protrusion 110 and the second protrusion 210 can be configured to be flat, and the circuit board 300 at such first protrusion 110 and the second protrusion 210 does not include a through hole. At these locations, the first protrusion 110 and the second protrusion 210 can cooperate to clamp the circuit board 300 in place. For example, Figure 4 The first protrusion 110 with a flat end is shown. It is easy to understand that Figure 4 In the illustrated embodiment, the end of the second protrusion 210 may also be configured to be flat.
[0040] Figure 8 is a schematic cross-sectional view of one embodiment of a compressor of the present application. For the sake of clarity, Figure 8The cross-sectional structure of the compressor is only schematically shown, and some details are omitted. The compressor may include: the controller 10 described above, the motor 20, etc. As shown in the figure, the second housing 200 and the first housing 100 are assembled together to surround the first cavity 101. In addition, the second housing 200 may also include a second cavity 102. In one embodiment, the first cavity 101 and the second cavity 102 are spaced apart. The circuit board 300 may be accommodated in the first cavity 101, and the motor 20 may be accommodated in the second cavity 102. The motor 20 and the circuit board 300 may be electrically connected through a conductive path 21, and the motor 20 may be operated by the controller 10 or the circuit board 300.
[0041] In the embodiment of the present application, the first cavity 101 is used to accommodate the circuit board 300 of the controller 10, and is therefore also referred to as a controller cavity. The second cavity 102 is used to accommodate the motor, and is therefore also referred to as a motor cavity.
[0042] The controller and compressor of the present application have the advantages of being simple and reliable, easy to use, and having good assembly performance, etc. The manufacturing process of the controller and compressor of the present application is simplified, and the manufacturing efficiency is improved.
