Detailed Implementation

[0051] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the invention. However, it will be apparent to those skilled in the art that embodiments of the invention may be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with embodiments of the invention.

[0052] Preferred embodiments of the present application will be described herein below with reference to the accompanying drawings. It should be noted that the terms "upper", "lower", and the like as used herein are intended to be illustrative only and are not limiting.

[0053] In this document, the ordinal numbers such as "first" and "second" cited in the present application are merely identifiers and have no other meaning, such as a particular order or the like.

[0054] For a thorough understanding of the present application, reference will be made to the following detailed description, in which preferred embodiments of the present application will be described. It should be noted that the present application is not limited to the particular details described herein. The preferred embodiments of the present application will be described in detail below with reference to the drawings.

[0055] A scroll set is provided. The scroll set can be used in a compressor. The compressor can be a scroll compressor. The compressor can be used in an air conditioning system of a vehicle 200. The volume of a suction space of the compressor using the scroll set can be adjusted as needed to facilitate control of the operation of the compressor. The suction space is a space where low pressure gas stays before entering a compression space 132 hereinafter. Herein, when the switch set connects the suction groove 125 to the compression space 132, the suction space includes the suction groove 125, the suction port 123, the suction gap 126, and the scroll tooth suction space 197. When the switch set disconnects the suction groove 125 from the compression space 132, the suction space includes the scroll tooth suction space 197. The scroll tooth suction space 197 is part of the housing cavity. The scroll tooth suction space 197 is located between the stationary body 121 and the orbiting body 171, and is located outside the outer contour of the whole formed by the orbiting scroll tooth and the stationary scroll tooth in the radial direction of the stationary body 121.

[0056] Please refer to Figures 1 to 18 The scroll set includes a scroll and a switch set. The scroll includes a body and a scroll tooth. The body is a cylindrical structure. The body has an axis. The body has an end face at one end thereof. The end face is a scroll face 124. The body has a surface opposite to the scroll face 124. The surface is a high pressure face. The body is recessed from the scroll face 124 in the axial direction of the body toward the high pressure face to form a suction groove 125. The suction groove 125 extends in the axial direction of the body. The body has a suction port 123. The suction port 123 extends in the radial direction of the body. The suction port 123 is connected to the suction groove 125 to form a suction passage 198.

[0057] As Figure 4As shown, one end of the scroll tooth is connected to the scroll disc disc face 124 to form a compression space 132 for compressing gas. The scroll tooth is a tooth scroll structure with continuously changing radius. The scroll tooth structure is substantially the same as the scroll tooth of the prior art compressor, and will not be described here.

[0058] Please refer to Figure 5 The projection of the compression space 132 on the scroll disc disc face 124 covers the projection of the suction groove 125 on the scroll disc disc face 124. In this way, the suction groove 125 is communicated to the compression space 132 through the opening on the scroll disc disc face 124. The scroll tooth has at least two radius portions. The radius of different radius portions is completely different. The compression space 132 includes at least two regions. The at least two regions and the at least two radius portions are one-to-one correspondence. The suction groove 125 extends through the at least two regions.

[0059] As Figures 10 to 18 The switch assembly is movably connected to the body portion. In the axial direction of the body portion, the position of the suction groove 125 and the position of the switch assembly at least partially overlap. The switch assembly can communicate the suction groove 125 to the compression space 132 (open the suction groove 125), and can block the communication between the suction groove 125 and the compression space 132 (close the suction groove 125).

[0060] When the suction groove 125 is communicated to the compression space 132, low-pressure gas can be transported to the compression space 132 through the suction groove 125 and the suction port 123, and low-pressure gas can be transported to the compression space 132 through the scroll tooth suction space 197, which can compress the low-pressure gas more quickly.

[0061] When the communication between the suction groove 125 and the compression space 132 is blocked, only the scroll tooth suction space 197 transports low-pressure gas to the compression space 132.

[0062] In this way, the switch assembly can be moved as needed to communicate the suction groove 125 to the compression space 132, or to block the communication between the suction groove 125 and the compression space 132.

[0063] It can be understood that in an embodiment not shown, the switch assembly can be located in the intake gap described below for opening or closing the intake gap.

[0064] In this embodiment, the arrangement of the suction port 123, the suction groove 125, and the switch assembly can move the switch assembly as needed to communicate the suction groove 125 to the compression space 132, or to block the communication between the suction groove 125 and the compression space 132, thereby changing the volume of the suction space; in addition, the volume of the suction space can be changed without moving the scroll disc, solving the problem of low efficiency of the compressor caused by the inclination of the scroll disc.

[0065] Preferably, as shown in Figure 4 and Figure 5 , the suction groove 125 comprises an arc-shaped portion configured as an arc-shaped structure. Specifically, the suction groove 125 is a channel-vortex structure with continuously changing radius. The rotation direction of the channel-vortex structure is the same as that of the tooth-vortex structure. Thus, the suction groove 125 extends along the extension direction of the tooth-vortex structure, and can transport low-pressure gas to the compression space 132 more quickly.

[0066] In an embodiment not shown, the suction groove comprises a straight portion configured to extend along a straight line.

[0067] In an embodiment not shown, the suction groove comprises at least two sub-grooves. The at least two sub-grooves are in communication or spaced apart. The gas inlet can be at least two corresponding to the at least two sub-grooves. Correspondingly, the switch assembly described below is provided at each sub-groove.

[0068] It can be understood that, in an embodiment not shown, the suction groove can have other structures. For example, a straight line structure extending along the radial direction of the body portion.

[0069] Further preferably, please continue to refer to Figure 4 and Figure 5 , the channel outer periphery surface 133 of the channel-vortex structure is attached to the tooth inner periphery surface 134 of the tooth-vortex structure. Thus, it is possible to avoid the gas in different areas of the compression space 132 from flowing through the suction groove 125.

[0070] It can be understood that, in an embodiment not shown, there is a gap between the channel-vortex structure and the tooth-vortex structure.

[0071] In another embodiment not shown, the channel inner periphery surface of the channel-vortex structure is attached to the tooth outer periphery surface of the tooth-vortex structure. The channel inner periphery surface is closer to the center of the channel-vortex structure than the corresponding channel outer periphery surface. The tooth outer periphery surface is farther away from the center of the tooth-vortex structure than the corresponding tooth inner periphery surface.

[0072] As shown in Figures 2 to 9 , the channel-vortex structure comprises at least two radius segment channels. The body is provided with a circular arc segment channel corresponding to the at least two radius segment channels. In the axial direction of the body portion, the radius segment channel is located at the corresponding circular arc segment channel. The positions of different circular arc segment channels are staggered in the axial direction of the body portion. The circular arc segment channel and the corresponding radius segment channel are connected end to end to form a circumferentially closed circular channel corresponding to the radius segment channel.

[0073] As shown in Figure 2 and Figure 3 , and Figures 10 to 18As shown, the switch assembly includes sliders corresponding to at least two radius segment channels. Each slider is an arc-shaped structure corresponding to the arc-shaped structure of its corresponding radius segment channel (the corresponding arc-shaped structures have the same radius and the same center). The slider is disposed within its corresponding circular channel. The slider is movably disposed between an open position and a closed position along the extension direction of the circular channel.

[0074] The slider in the open position is located outside the corresponding radius segment of the channel. At this time, the suction groove 125 is fully open, and the suction groove 125 is fully connected to the compression space 132. The communication area between the suction groove 125 and the compression space 132 is at its maximum. The suction groove 125 can deliver low-pressure gas to the compression space 132 at the fastest speed.

[0075] The slider in the closed position covers the corresponding radius segment channel. In this way, the slider cuts off the connection between the corresponding radius segment channel and the compression space 132.

[0076] The slider can be moved to any position between the open and closed positions as needed, thereby controlling the size of the communication area between the suction groove 125 and the compression space 132, and thus controlling the speed at which the suction groove 125 delivers low-pressure gas to the compression space 132.

[0077] More preferably, the arc length of the slider's arc-shaped structure is greater than or equal to the arc length of the radius segment channel. Therefore, when the slider is in the closed position, leakage of low-pressure gas from the suction groove 125 into the compression space 132 can be prevented.

[0078] like Figures 4 to 18 As shown, the vortex tooth includes a first radius portion 194, a second radius portion 195, and a third radius portion 196. The radius of the first radius portion 194 is larger than the radius of the second radius portion 195. The radius of the second radius portion 195 is larger than the radius of the third radius portion 196. The aforementioned regions include a first region 135, a second region 136, and a third region 137. The first region 135 corresponds to the first radius portion 194. The second region 136 corresponds to the second radius portion 195. The third region 137 corresponds to the third radius portion 196. Figure 5 In the middle, the first region 135, the second region 136, and the third region 137 are separated by dotted lines. The air intake groove 125 extends through the first region 135, the second region 136, and the third region 137.

[0079] Please refer to Figure 9The channel vortex structure includes a first radius section channel 127 with a first radius R1, a second radius section channel 128 with a second radius R2, and a third radius section channel 129 with a third radius R3. R1>R2>R3. The first radius section channel 127 is located in the first region 135. The second radius section channel 128 is located in the second region 136. The third radius section channel 129 is located in the third region 137. Figure 9 In the first radius section channel 127, the second radius section channel 128, and the third radius section channel 129 are separated by a dashed line.

[0080] Correspondingly, as Figures 10 to 12 The body part is provided with a first arc section channel 144 corresponding to the first radius section channel 127. The first arc section channel 144 has a radius R1. The center of the first arc section channel 144 is the center of the first radius section channel 127. In the axial direction of the body part, the first arc section channel 144 is located at the first radius section channel 127. The first arc section channel 144 and the first radius section channel 127 are connected end to end to form a first circular channel corresponding to the first radius section channel 127. The circular channel includes the first circular channel.

[0081] As Figures 13 to 15 The body part is provided with a second arc section channel 154 corresponding to the second radius section channel 128. The second arc section channel 154 has a radius R2. The center of the second arc section channel 154 is the center of the second radius section channel 128. In the axial direction of the body part, the second arc section channel 154 is located at the second radius section channel 128. The second arc section channel 154 and the second radius section channel 128 are connected end to end to form a second circular channel corresponding to the second radius section channel 128. The circular channel includes the second circular channel.

[0082] As Figures 16 to 18 The body part is provided with a third arc section channel 164 corresponding to the third radius section channel 129. The third arc section channel 164 has a radius R3. The center of the third arc section channel 164 is the center of the third radius section channel 129. In the axial direction of the body part, the third arc section channel 164 is located at the third radius section channel 129. The third arc section channel 164 and the third radius section channel 129 are connected end to end to form a third circular channel corresponding to the third radius section channel 129. The circular channel includes the third circular channel.

[0083] Please return Figure 2 And Figure 3 In the axial direction of the body part, the first circular channel, the second circular channel, and the third circular channel are staggered two by two.

[0087] Please refer to Figures 10 to 18 , further preferably, the switch assembly further includes a driving component. The driving component is connected to the body part. The driving component is located in the circular channel. One end of the driving component is connected to the slider for driving the slider to move along the extension direction of the circular channel. The driving component is a circular ring driving structure. The driving component is a driving component of the prior art, which will not be described here. Thus, it is convenient to control the movement of the slider.

The air inlet 123 extends to the suction groove 125 along the radial direction of the body portion, thereby communicating with the suction groove 125. In this way, the air inlet 123 can be machined on the outer circumferential surface of the body portion, and the machining of the air inlet 123 is convenient.

[0094] The outer circumferential surface of the body portion is attached to the inner surface of the second shell 112 constituting the shell cavity 113. In this way, the connection between the scroll and the second shell 112 is firm. The outer circumferential surface of the body portion is recessed to form an air intake gap 126 along the radial direction of the body portion. The air inlet 123 extends along the axial direction of the body portion. Along the axial direction of the body portion, one end of the air intake gap 126 communicates with the air inlet 123, and the other end of the air inlet 123 penetrates the scroll face 124. In this way, the low-pressure gas located in the scroll tooth intake space 197 can enter the suction groove 125 through the air intake gap 126.

[0095] Further preferably, the scroll is a static scroll 120.

[0096] In an embodiment not shown, the switching assembly can also be other forms as long as it can connect the suction groove to the compression space and cut off the connection between the suction groove and the compression space. For example, the switching assembly can be elastically deformed to connect the suction groove to the compression space and cut off the connection between the suction groove and the compression space by elastic deformation.

[0097] The application also provides a compressor. The compressor comprises the scroll plate as described above.

[0098] In the embodiment, the compressor comprises the scroll plate as described above, the suction inlet 123, the suction groove 125, and the switching assembly, which can be moved as needed to connect the suction groove 125 to the compression space 132 or cut off the connection between the suction groove 125 and the compression space 132, thereby changing the volume of the suction space. In addition, the volume of the suction space can be changed without moving the scroll plate, thereby solving the problem that the scroll plate may be inclined to cause low efficiency of the compressor.

[0099] Please refer to Figures 1 to 3 The compressor comprises a first housing 111, a second housing 112, an end cover 116, a stationary scroll plate 120, a movable scroll plate 170, a crankshaft 180, a stator 190, a rotor 191, and a bearing 192.

[0100] One end of the second housing 112 is connected to one end of the first housing 111, and the other end of the first housing 111 is connected to the end cover 116, thereby forming a housing cavity 113. The first housing 111 has an air inlet 114. The second housing 112 has an air outlet 115. The stationary scroll plate 120, the movable scroll plate 170, the crankshaft 180, the stator 190, the rotor 191, and the bearing 192 are all arranged in the housing cavity 113.

[0101] The crankshaft 180 is rotatably connected to the first housing 111 through the bearing 192. The stator 190 is arranged in the first housing 111. The rotor 191 is rotatably connected to the crankshaft 180. In this way, the stator 190 and the rotor 191 cooperate to drive the crankshaft 180 to rotate.

[0102] The stationary scroll plate 120 is the scroll plate as described above. The stationary scroll plate 120 comprises a stationary body portion 121 (an example of a body portion) and stationary scroll teeth 130 (an example of scroll teeth). The movable scroll plate 170 comprises a movable body portion 171 and movable scroll teeth 172. The structure of the movable scroll teeth 172 is substantially the same as the structure of the scroll teeth of the movable scroll plate of the scroll compressor of the prior art, which will not be described here.

[0103] The static scroll 120 is fixedly connected to the second housing 112. In this way, the side of the housing cavity 113, which is away from the static scroll 120, constitutes a high-pressure cavity 193. The high-pressure cavity 193 is in communication with the gas inlet and gas outlet 115 of the static scroll 120. The dynamic scroll 170 is rotatably connected to the first housing 111. The crankshaft 180 is connected to the dynamic body portion 171 of the dynamic scroll 170 to drive the dynamic scroll 170 to rotate translationally. The dynamic body portion 171 is provided with a dynamic scroll turbine gas inlet passage 173. The dynamic scroll turbine gas inlet passage 173 penetrates the dynamic body portion 171.

[0104] Please refer to Figures 2 to 7 , the dynamic scroll teeth 172 extend into the compression space 132. When the dynamic scroll 170 rotates translationally, the dynamic scroll teeth 172 and the static scroll teeth 130 cooperate to compress the gas in the compression space 132. The compressed gas can be discharged into the high-pressure cavity 193 through the exhaust hole 131 of the static scroll 120.

[0105] Please refer to Figure 2 and Figure 3 , the slider is in the open position, and when the compressor is working, the gas outside the compressor flows in the direction indicated by the dashed arrows of Figure 2 and Figure 3 . Specifically, the gas outside the compressor enters the housing cavity 113 through the gas inlet 114, then flows through the stator 190 and the rotor 191, and then flows into the dynamic scroll turbine gas inlet passage 173; then from the dynamic scroll turbine gas inlet passage 173 into the scroll tooth gas inlet space 197. Among the low-pressure gas entering the scroll tooth gas inlet space 197, part of it enters the compression space 132 in the radial direction of the static body portion 121, and the other part enters the gas inlet gap 126 in the axial direction of the static body portion 121, then enters the suction groove 125 through the gas inlet 123, and then enters the compression space 132 from the suction groove 125; the gas compressed through the compression space 132 enters the high-pressure cavity 193 through the exhaust hole 131, and is discharged from the compressor through the gas outlet 115.

[0106] It should be noted that the connection mode and interaction mode of the stator 190, the rotor 191, the crankshaft 180 and the dynamic scroll 170 are prior art, and the dynamic scroll teeth 172 and the static scroll teeth 130 cooperate to compress the gas in the compression space 132 are also prior art, which will not be described here.

[0107] It can be understood that in an embodiment not shown, the static scroll can be a prior art static scroll. The dynamic scroll 170 is the aforementioned scroll. At this time, the dynamic scroll includes a dynamic body portion (an example of the body portion) and dynamic scroll teeth (an example of the scroll teeth).
