Description

Technical Field

[0001] The utility model belongs to the technical field of motors, and in particular relates to a scroll compressor and an air conditioner. Background Art

[0002] Scroll compressors typically use guide pins to circumferentially position the fixed scroll. Before tightening the guide pin screws, the guide pins are not fixed in place. Usually, the fixed scroll is pre-positioned using a positioning tool before the guide pins are installed. This makes installation of the guide pins difficult and inefficient. Utility Model Content

[0003] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] In view of this, in the first aspect, the present invention proposes a scroll compressor, comprising: a bearing seat, which is provided with a first positioning hole; a fixed scroll, which is provided with a second positioning hole; and a guide member, which is passed through the first positioning hole and the second positioning hole, and is used to limit the fixed scroll along the circumference of the fixed scroll.

[0005] The scroll compressor provided by the present invention is provided with positioning holes on both the fixed scroll and the bearing seat. After the second positioning hole on the fixed scroll is aligned with the first positioning hole on the bearing seat, the guide member is inserted into the second positioning hole and the first positioning hole in sequence, so that the guide member can limit the fixed scroll, and the fixed scroll is restricted from rotating circumferentially relative to the bearing seat, thereby achieving fixed position of the fixed scroll.

[0006] In the related art, the guide member is typically not fixed in position before its screws are tightened. To ensure accurate positioning of the guide member during installation, the fixed scroll is typically pre-positioned using a positioning fixture. The guide member is then installed, and the positioning fixture is removed after the screws are tightened to ensure the guide member does not move. This results in low installation efficiency.

[0007] In this solution, a positioning hole coaxial with the fixed scroll is provided on the bearing seat, and the guide member is installed into the first positioning hole on the bearing seat after passing through the second positioning hole, so that the installation position of the guide member is fixed and accurate. When the guide member is fixed on the bearing seat, no additional positioning tooling is required for pre-positioning, which can simplify the installation steps of the fixed scroll, reduce the difficulty of installing the fixed scroll, and help improve the assembly efficiency of the scroll compressor.

[0008] In addition, the scroll compressor according to the above technical solution provided by the present invention may also have the following additional technical features:

[0009] In some technical solutions, optionally, the scroll compressor further includes: a locking member connected to the guide member and the bearing seat, and the locking member is used to lock the guide member on the bearing seat.

[0010] When the guide member is inserted into the second positioning hole and the first positioning hole in sequence, the guide member is locked on the bearing seat using a locking member. The locking member limits the guide member so that the guide member is not easily separated from the first mounting hole and the second mounting hole, ensuring that the guide member can stably limit the fixed scroll and ensure that the fixed scroll can be stably fixed on the bearing seat.

[0011] In some technical solutions, optionally, a through hole is provided on the guide member along the length direction of the guide member, and a portion of the locking member passes through the through hole.

[0012] After the guide member is inserted into the second positioning hole and the first positioning hole in sequence, the locking member is inserted into the through hole on the guide member. The locking member occupies a part of the space inside the guide member, so that a part of the locking member overlaps with the guide member in space, which is beneficial to improving the space utilization inside the scroll compressor.

[0013] In some technical solutions, optionally, one end of the locking member abuts against the fixed scroll, and one end of the locking member is used to limit the guide member from being separated from the second positioning hole.

[0014] After the locking member is connected to the bearing seat, the end of the locking member does not extend into the through-hole on the guide member, and the end of the locking member abuts against the fixed scroll. Since the portion of the locking member that passes through the through-hole is connected to the bearing seat, when the end of the locking member abuts against the fixed scroll, the end of the locking member can limit the fixed scroll, restricting the fixed scroll from moving axially relative to the bearing seat, thereby achieving axial limitation of the fixed scroll. The guide member is used to circumferentially limit the fixed scroll, thereby ensuring the stability of the fixed scroll's installation position.

[0015] One end of the locking member has a greater width than other portions of the locking member, thereby ensuring that a portion of the locking member can pass through the through-hole while the one end of the locking member cannot penetrate the through-hole and abut against the fixed scroll. Furthermore, because the one end of the locking member can abut against the fixed scroll, the one end of the locking member can limit the position of the guide member. That is, the one end of the locking member abuts against the end of the guide member, allowing the locking member to limit the axial movement of the guide member along the bearing seat, preventing the guide member from disengaging from the second mounting hole, and ensuring that the guide member can stably limit the circumferential position of the fixed scroll.

[0016] In some technical solutions, optionally, a mounting hole is provided on the bearing seat, the mounting hole is communicated with the first positioning hole, and a portion of the locking member passing through the first positioning hole is connected to the mounting hole.

[0017] The locking piece is passed through the through hole of the guide piece, and the length of the locking piece is greater than the length of the through hole, so that a part of the locking piece passes through the through hole, and a part of the locking piece extending through the through hole can be extended into the mounting hole. This part of the locking piece is connected to the mounting hole, thereby limiting the locking piece from being separated from the bearing seat, ensuring that the locking piece can stably limit the fixed scroll and the guide piece.

[0018] In some technical solutions, optionally, the locking member includes a screw, and the mounting hole includes a threaded hole; or the locking member includes a pin, and the mounting hole includes a pin hole.

[0019] A screw can be used as a locking member, with a portion of the screw passing through the through hole and a portion of the screw extending out of the through hole being connected to the threaded hole. The threaded hole limits the screw so that the screw is not easily separated from the bearing seat.

[0020] Alternatively, a pin can be used as a locking member, with a portion of the pin passing through the through hole and a portion of the pin extending out of the through hole connected to the pin hole. The pin and the pin hole are connected by an interference fit, and the pin hole limits the pin, making it difficult for the pin to fall off the bearing seat.

[0021] In some technical solutions, optionally, the scroll compressor further includes: a buffer gasket located between the end of the locking member and the fixed scroll.

[0022] After the locking element is installed, a buffer washer is positioned between the end of the locking element and the fixed scroll. The buffer washer protects the fixed scroll from damage caused by the end of the locking element. Furthermore, the buffer washer prevents the locking element from loosening, which helps improve the installation stability of the locking element.

[0023] In some technical solutions, optionally, the bearing seat includes: a bearing seat body; a first end plate, arranged on the outer edge of the bearing seat body, and a first positioning hole is arranged on the first end plate; the fixed scroll includes: a scroll body; a second end plate, arranged on the outer edge of the scroll body, along the axial direction of the bearing seat, the second end plate is arranged opposite to the first end plate, and the second positioning hole is arranged on the second end plate.

[0024] The first end plate is arranged on the bearing seat body, and the first positioning hole is opened on the first end plate. Therefore, there is no need to increase the radial dimension of the entire circle of the bearing seat body, but only to increase the radial dimension at a part of the outer edge of the bearing seat body. That is, the first end plate is only arranged on a part of the outer edge of the bearing seat body, which can reduce the volume of the bearing seat and reduce the space occupied by the bearing seat.

[0025] Similarly, the second end plate is arranged on the scroll body, the second positioning hole is opened on the second end plate, and the second end plate is arranged on a part of the outer edge of the scroll body, which can reduce the volume of the fixed scroll and reduce the space occupied by the fixed scroll.

[0026] In some technical solutions, optionally, there are multiple first positioning holes, and the multiple first positioning holes are distributed at intervals along the circumference of the bearing seat, and the number of second positioning holes and guide members is the same as the number of first positioning holes.

[0027] There are multiple guide members, first positioning holes, and second positioning holes, and each guide member needs to be inserted into the second positioning hole and the first positioning hole, so that multiple guide members can simultaneously limit the circumferential position of the fixed scroll. If only one guide member is provided, when force is applied to the fixed scroll, the fixed scroll may move slightly in the circumferential direction. Therefore, the present solution limits the number of guide members to multiple, and multiple guide members simultaneously limit the fixed scroll to prevent the fixed scroll from moving in the circumferential direction, thereby eliminating the need to use positioning fixtures to pre-position the fixed scroll.

[0028] In a second aspect, the present invention proposes an air conditioner, comprising: a scroll compressor as in the above technical solution. Therefore, the air conditioner provided by the present invention has all the beneficial effects of the scroll compressor provided in the above technical solution.

[0029] Additional aspects and advantages of the present invention will become apparent in the following description or will be understood through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0042] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0043] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0044] Refer to the following Figures 1 to 9 The present invention will now be described in detail with reference to a scroll compressor and an air conditioner according to some embodiments of the present invention.

[0045] Combine Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, in some embodiments of the present invention, a scroll compressor 100 is proposed, comprising: a bearing seat 110, a fixed scroll 120 and a guide member 130, wherein the bearing seat 110 is provided with a first positioning hole 111, the fixed scroll 120 is provided with a second positioning hole 121, and the guide member 130 is inserted into the first positioning hole 111 and the second positioning hole 121, and along the circumference of the fixed scroll 120 ( Figure 1The guide member 130 is used to limit the fixed scroll 120 .

[0046] The scroll compressor 100 provided in this embodiment is provided with positioning holes on both the fixed scroll 120 and the bearing seat 110. After the second positioning hole 121 on the fixed scroll 120 is aligned with the first positioning hole 111 on the bearing seat 110, the guide member 130 is inserted into the second positioning hole 121 and the first positioning hole 111 in sequence, so that the guide member 130 can limit the fixed scroll 120, and the fixed scroll 120 is restricted from rotating circumferentially relative to the bearing seat 110, thereby achieving the fixation of the position of the fixed scroll 120.

[0047] In the related art, the guide member is typically not fixed in position before its screws are tightened. To ensure accurate positioning of the guide member during installation, the fixed scroll is typically pre-positioned using a positioning fixture. The guide member is then installed, and the positioning fixture is removed after the screws are tightened to ensure the guide member does not move. This results in low installation efficiency.

[0048] In the present solution, a positioning hole coaxial with the fixed scroll 120 is provided on the bearing seat 110, and the guide member 130 is installed into the first positioning hole 111 on the bearing seat 110 after passing through the second positioning hole 121, so that the initial installation position of the guide member 130 is fixed and accurate. When the guide member 130 is fixed on the bearing seat 110, no additional positioning tooling is required for pre-positioning, which can simplify the installation steps of the fixed scroll 120, reduce the difficulty of installing the fixed scroll 120, and help improve the assembly efficiency of the scroll compressor 100.

[0049] like Figure 9 As shown, in a possible application, the scroll compressor 100 further includes a casing 160, a movable scroll 170 and a driving mechanism 180. The casing 160 is composed of a cylindrical housing assembly 161, an upper cover 162 and a lower cover 163 connected into a whole by welding. The bearing seat 110 is fixed in the casing 160. The fixed scroll 120 and the movable scroll 170 are placed between the bearing seat 110 and the upper cover 162. When the driving mechanism 180 rotates, it drives the movable scroll 170 to move. Due to the limitation of the cross slip ring connected to the movable scroll 170 and the bearing seat 110, the movable scroll 170 can only perform a circumferential orbital translation, and will not perform a rotational motion along its own axis. The driving mechanism 180 includes a motor 181 and a drive shaft 182. The motor 181 is used to drive the drive shaft 182 to rotate, and the drive shaft 182 is used to drive the movable scroll 170 to operate.

[0050] The first scroll 190 on the fixed scroll 120 and the second scroll on the orbiting scroll mesh with each other to form a plurality of compression chambers for compressing fluid.

[0051] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, optionally, the scroll compressor 100 further includes: a locking member 140 , the locking member 140 being connected to the guide member 130 and the bearing seat 110 , and the locking member 140 being used to lock the guide member 130 on the bearing seat 110 .

[0052] When the guide member 130 is inserted into the second positioning hole 121 and the first positioning hole 111 in sequence, the locking member 140 is used to lock the guide member 130 on the bearing seat 110. The locking member 140 limits the guide member 130 so that the guide member 130 is not easily separated from the first mounting hole 112 and the second mounting hole 112, ensuring that the guide member 130 can stably limit the fixed vortex 120 and ensure that the fixed vortex 120 can be stably fixed on the bearing seat 110.

[0053] In other embodiments, the guide member 130 itself can be fixed to the bearing seat 110 by interference fit or threaded engagement, thereby eliminating the need for the locking member 140 .

[0054] Combine Figure 2 and Figure 8 As shown, in some embodiments, optionally, along the length direction of the guide member 130 ( Figure 2 The guide member 130 is provided with a through hole 131 , and a portion of the locking member 140 passes through the through hole 131 .

[0055] After the guide member 130 is inserted into the second positioning hole 121 and the first positioning hole 111 in sequence, the locking member 140 is inserted into the through hole 131 on the guide member 130. The locking member 140 occupies a part of the space inside the guide member 130, so that a part of the locking member 140 overlaps with the guide member 130 in space, which is beneficial to improving the space utilization inside the scroll compressor 100.

[0056] Combine Figure 1 、 Figure 2 and Figure 3 As shown, in some embodiments, optionally, one end of the locking member 140 abuts against the fixed scroll 120 , and one end of the locking member 140 is used to restrict the guide member 130 from being separated from the second positioning hole 121 .

[0057] After the locking member 140 is connected to the bearing seat 110, the end of the locking member 140 does not extend into the through hole 131 on the guide member 130, and the end of the locking member 140 abuts against the fixed scroll 120. Since the portion of the locking member 140 that passes through the through hole 131 is connected to the bearing seat 110, when the end of the locking member 140 abuts against the fixed scroll 120, the end of the locking member 140 can limit the fixed scroll 120, restricting the fixed scroll 120 from moving relative to the bearing seat 110 along the axial direction of the bearing seat 110, thereby achieving axial limitation of the fixed scroll 120. The guide member 130 is used to circumferentially limit the fixed scroll 120, thereby ensuring the stability of the installation position of the fixed scroll 120.

[0058] One end of the locking member 140 has a larger width than other positions of the locking member 140, thereby ensuring that a portion of the locking member 140 can pass through the through-hole 131, while one end of the locking member 140 cannot penetrate the through-hole 131 and abut against the fixed scroll 120. In addition, because one end of the locking member 140 can abut against the fixed scroll 120, the one end of the locking member 140 can limit the guide member 130. That is, the one end of the locking member 140 abuts against the end of the guide member 130, so that the locking member 140 can limit the axial movement of the guide member 130 along the bearing seat 110, prevent the guide member 130 from disengaging from the second mounting hole 112, and ensure that the guide member 130 can stably limit the circumferential position of the fixed scroll 120.

[0059] Combine Figure 2 and Figure 5 As shown, in some embodiments, optionally, a mounting hole 112 is provided on the bearing seat 110 , the mounting hole 112 is communicated with the first positioning hole 111 , and a portion of the locking member 140 passing through the first positioning hole 111 is connected to the mounting hole 112 .

[0060] The locking member 140 is passed through the through hole 131 of the guide member 130. The length of the locking member 140 is greater than the length of the through hole 131, so that a part of the locking member 140 passes through the through hole 131, and a part of the locking member 140 extending out of the through hole 131 can be extended into the mounting hole 112. This part of the locking member 140 is connected to the mounting hole 112, thereby limiting the locking member 140 from being separated from the bearing seat 110, ensuring that the locking member 140 can stably limit the fixed scroll 120 and the guide member 130.

[0061] Combine Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7As shown, in some embodiments, optionally, the locking member 140 includes a screw 141 and the mounting hole 112 includes a threaded hole 113 . Alternatively, the locking member 140 includes a pin 142 and the mounting hole 112 includes a pin hole 114 .

[0062] A screw 141 can be used as a locking member 140. A portion of the screw 141 passes through the through hole 131, and a portion of the screw 141 extending out of the through hole 131 is connected to the threaded hole 113. The threaded hole 113 limits the screw 141 so that the screw 141 is not easily separated from the bearing seat 110.

[0063] Alternatively, a pin 142 can be used as a locking member 140, with a portion of the pin 142 passing through the through hole 131, and a portion of the pin 142 extending out of the through hole 131 being connected to the pin hole 114, and the pin 142 and the pin hole 114 being connected by an interference fit, and the pin hole 114 limiting the pin 142 so that the pin 142 is not easily separated from the bearing seat 110.

[0064] In a possible application, the threaded hole 113 is coaxially arranged with the first positioning hole 111 , and the pin hole 114 is coaxially arranged with the first positioning hole 111 .

[0065] Taking the mounting hole 112 as an example of the threaded hole 113, the aperture of the threaded hole 113 is smaller than the aperture of the first positioning hole 111 to prevent the guide member 130 from extending into the threaded hole 113. The screw 141 needs to be inserted into the second positioning hole 121, the first positioning hole 111 and the threaded hole 113 in sequence.

[0066] Combine Figure 1 and Figure 2 As shown, in some embodiments, optionally, the scroll compressor 100 further includes: a buffer washer 150 , which is located between the end of the locking member 140 and the fixed scroll 120 .

[0067] After the locking member 140 is installed, the buffer washer 150 is located between the end of the locking member 140 and the fixed scroll 120. The buffer washer 150 protects the fixed scroll 120 and prevents the end of the locking member 140 from damaging the surface of the fixed scroll 120. In addition, the buffer washer 150 can also prevent the locking member 140 from loosening, which helps to improve the installation stability of the locking member 140.

[0068] Exemplarily, the buffer gasket 150 may be a rubber gasket or a metal gasket.

[0069] Combine Figure 4 、 Figure 5 and Figure 6As shown, in some embodiments, optionally, the bearing seat 110 includes: a bearing seat body 115 and a first end plate 116, the first end plate 116 is provided on the outer edge of the bearing seat body 115, and the first positioning hole 111 is provided on the first end plate 116. The fixed scroll 120 includes: a scroll body 122 and a second end plate 123, the second end plate 123 is provided on the outer edge of the scroll body 122, and along the axial direction of the bearing seat 110 ( Figure 3 The second end plate 123 is disposed opposite to the first end plate 116 , and the second positioning hole 121 is disposed on the second end plate 123 .

[0070] The first end plate 116 is arranged on the bearing seat body 115, and the first positioning hole 111 is opened on the first end plate 116. Therefore, there is no need to increase the radial dimension of the entire circle of the bearing seat body 115, but only increase the radial dimension at a part of the outer edge of the bearing seat body 115, that is, the first end plate 116 is only arranged on a part of the outer edge of the bearing seat body 115, which can reduce the volume of the bearing seat 110 and reduce the space occupied by the bearing seat 110.

[0071] In a possible application, the first end plate 116 and the bearing seat body 115 are an integral structure, and the outer peripheral wall of the bearing seat body 115 extends radially to form the first end plate 116 .

[0072] Similarly, the second end plate 123 is arranged on the scroll body 122, and the second positioning hole 121 is opened on the second end plate 123. The second end plate 123 is arranged on a part of the outer edge of the scroll body 122, which can reduce the volume of the fixed scroll 120 and reduce the space occupied by the fixed scroll 120.

[0073] In a possible application, the second end plate 123 and the scroll body 122 are an integral structure, and the outer peripheral wall of the scroll body 122 extends radially to form the second end plate 123 .

[0074] Combine Figure 4 、 Figure 5 and Figure 6 As shown, in some embodiments, optionally, there are multiple first positioning holes 111, and the multiple first positioning holes 111 are distributed at circumferential intervals along the bearing seat 110, and the number of second positioning holes 121 and guide members 130 are the same as the number of first positioning holes 111.

[0075] The number of guide members 130, first positioning holes 111, and second positioning holes 121 is multiple, and each guide member 130 needs to be inserted into the second positioning hole 121 and the first positioning hole 111, so that multiple guide members 130 can simultaneously limit the circumferential position of the fixed scroll 120. If only one guide member 130 is provided, when force is applied to the fixed scroll 120, the fixed scroll 120 may move slightly in the circumferential direction. Therefore, in this solution, the number of guide members 130 is limited to multiple, and multiple guide members 130 simultaneously limit the fixed scroll 120 to prevent the fixed scroll 120 from moving in the circumferential direction, thereby eliminating the need to use positioning fixtures to pre-position the fixed scroll.

[0076] Exemplarily, the number of the first positioning holes 111 and the number of the second positioning holes 121 are both no less than three.
