Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to an end cover assembly and a compressor. Background Art

[0002] As the level of intelligence increases, air conditioning systems require increasingly refined control. Temperature, as the most direct and effective monitoring method, is often used to adjust control logic and achieve efficient system operation. Currently, systems often use temperature sensors to monitor the temperature of system compressors. The installation method and corresponding mounting structure of the temperature sensor have a significant impact on the accuracy of temperature monitoring and the reliability of the temperature sensor itself.

[0003] In the current installation method, the temperature sensor is placed near the compressor's exhaust pipe. Due to the exhaust pipe's structure and assembly process requirements, the temperature sensor's installation position is limited, forcing it to be relatively far from the compressor body. This results in the temperature sensor being able to monitor the exhaust pipe's exhaust temperature, but unable to monitor the actual temperature inside the compressor body due to the distance restriction, resulting in inaccurate temperature detection.

[0041] The present invention will be further described below with reference to the accompanying drawings.

[0042] Example 1

[0043] An embodiment of the present invention provides an end cover assembly 1, which is configured to be mounted on a top cover 2 of a compressor. A bottom portion of the end cover assembly 1 in contact with the top cover 2 is configured with an assembly groove 13, and the assembly groove 13 is formed with a notch on the bottom surface of the end cover assembly 1.

[0044] The assembly groove 13 is configured to form an assembly cavity together with the top cover 2 for accommodating the temperature sensing package 3 , and the notch is configured to allow the temperature sensing package 3 in the assembly cavity to contact the top cover 2 .

[0045] Specifically, the present invention designs the structure of the end cap assembly 1 and integrates the installation structure of the temperature sensing package 3 into the end cap assembly 1, thus solving the problems of the prior art. Figure 1 and Figure 2As shown, the bottom of the end cover assembly 1 is constructed with an assembly groove 13, and the notch of the assembly groove 13 is located on the bottom surface of the end cover assembly 1. When the end cover assembly 1 is installed on the top cover of the compressor, the bottom surface of the end cover assembly 1 is in contact with the surface of the top cover, and the top cover also closes the notch of the assembly groove 13, so that the top cover and the assembly groove 13 together form a cavity, that is, an assembly cavity for the temperature sensing package 3 to be installed. The temperature sensing package 3 installed in the assembly cavity can have its bottom contact with the surface of the top cover through the notch of the assembly groove 13, and then the temperature sensing package 3 can directly detect the temperature inside the compressor through the top cover of the compressor housing, thereby ensuring the accuracy of temperature detection.

[0046] Furthermore, the end cover assembly 1 includes an end cover body 11 and an insulating pad 12 arranged at the bottom of the end cover body 11. The insulating pad 12 is constructed with an assembly opening 121 that penetrates the upper insulating pad 12 in the thickness direction. The end cover body 11 is constructed with a baffle 111 that corresponds to the assembly opening 121 and covers the assembly opening 121. The baffle 111 and the assembly opening 121 together form an assembly groove 13.

[0047] Specifically, as shown in the accompanying drawings Figure 2 and Figure 3 As shown, the end cap assembly 1 adopts a split structure to form the installation structure of the temperature sensing bulb 3. The insulating gasket 12 of the end cap assembly 1 is installed at the bottom of the end cap body 11. The assembly groove 13 of the end cap assembly 1 is formed by the assembly opening 121 on the insulating gasket 12 and the blocking piece 111 of the end cap body 11. The assembly opening 121 serves as the main body of the assembly groove 13. When the end cap body 11 and the insulating gasket 12 are assembled, the blocking piece 111 on the end cap body 11 corresponds to the upper part of the assembly opening 121 and covers the assembly opening 121, thereby forming the assembly groove 13.

[0048] In this embodiment, the end cap assembly 1 adopts a split structure to form the mounting structure of the temperature-sensing bulb 3, which can effectively reduce the deformation and stress of the temperature-sensing bulb 3. The principle is that the split structure has a certain assembly gap between each other, which can cope with the deformation caused by the high temperature during operation of the compressor and achieve a buffering effect on the deformation, thereby avoiding causing excessive deformation of the temperature-sensing bulb 3 installed therein, and further avoiding the problem of stress concentration in the temperature-sensing bulb 3. In addition, the end cap body 11 of this embodiment is made of a hard material, and the insulating pad 12 is made of a soft material, further ensuring that the deformation and stress of the temperature-sensing bulb 3 are effectively reduced.

[0049] The deformation and stress simulation results of the split structure adopted by the end cover assembly 1 of this embodiment are shown in the attached figure Figure 14 and Figure 15In addition, under the same external force (10N in this embodiment), the deformation and stress simulation results of the split structure and the integral structure are compared as shown in the following table. The deformation is reduced by 6% and the stress is reduced by 22%, indicating that the split structure of this embodiment can effectively improve the deformation and stress of the temperature sensing package 33.

[0050] Integrated structure Split structure Difference ratio Maximum deformation (mm) 0.00408 0.00385 0.00023 ↓6％ Maximum stress (MPa) 6.0367 4.7313 1.3054 ↓22％

[0051] Furthermore, a protrusion 122 is constructed on the first surface of the insulating gasket 12 close to the end cover body 11, and the protrusion 122 is located at the edge of the assembly opening 121 and extends along the edge of the assembly opening 121; wherein the baffle 111 is constructed to cover the top of the protrusion 122 to form an assembly groove 13.

[0052] Specifically, as shown in the accompanying drawings Figure 2 and Figure 3 As shown, a protrusion 122 is formed on the surface of the insulating gasket 12, and the protrusion 122 is located at the edge of the assembly opening 121. With respect to the assembly groove 13, the inner wall of the assembly opening 121 and the inner wall of the protrusion 122 together form the groove wall of the assembly groove 13. The purpose of providing the protrusion 122 is to appropriately reduce the overall thickness of the insulating gasket 12 while ensuring the depth of the assembly groove 13, thereby reducing the material used for the end cap assembly 1 and reducing the cost.

[0053] Optionally, the protrusion 122 extends continuously or discontinuously along the edge of the assembly opening 121; wherein, the protrusion 122 that extends discontinuously along the edge of the assembly opening 121 is constructed with at least one disconnecting portion 1221 in its extension direction, and the disconnecting portion 1221 is constructed with a fracture for allowing the temperature sensing package 3 to enter and exit the assembly groove 13.

[0054] Specifically, as needed, the protrusion 122 can be continuously extended along the edge of the assembly opening 121 to surround a circle, or it can be discontinuously extended to form multiple disconnected portions 1221 at discontinuous positions. In this embodiment, it is preferred that the protrusion 122 be discontinuously extended along the edge of the assembly opening 121, as shown in the accompanying drawings. Figure 3 As shown, the formed disconnecting portion 1221 forms a break on the colored pen of the assembly groove 13 , which allows the temperature sensing package 3 to be loaded into or unloaded from the assembly groove 13 , thereby facilitating the installation of the temperature sensing package 3 .

[0055] Furthermore, the protrusion 122 is constructed with a plurality of disconnected portions 1221 in its extending direction. The disconnected portions 1221 have a plurality of different orientations, so that one or more temperature sensing packages 3 can be installed into the assembly groove 13 from different directions.

[0056] Specifically, as shown in the accompanying drawings Figure 3 Shown with Figure 8As shown, the discontinuously extended protrusion 122 has a plurality of disconnected portions 1221, and the plurality of disconnected portions 1221 form a plurality of fractures on the groove wall of the assembly groove 13. The plurality of fractures have different orientations, so the temperature sensing package 3 can be installed into the assembly groove 13 from different disconnected portions 1221, and thus the installation direction of the temperature sensing package 3 also has a plurality of options to meet different needs.

[0057] Optionally, the multiple disconnecting portions 1221 include at least one opposing group, each opposing group includes two disconnecting portions 1221 facing each other, and the axes of the disconnecting portions of the two disconnecting portions 1221 in the same group are collinear.

[0058] Specifically, as shown in the accompanying drawings Figure 3 As shown, two of the multiple disconnected portions 1221 are opposite to each other to form a pair of opposite groups. The temperature sensing package 3 can be installed into the assembly groove 13 from two completely opposite directions based on the two disconnected portions 1221 of the opposite group, as shown in the accompanying drawings. Figure 3 and Figure 4 As shown in the attached figure Figure 7 and Figure 8 As shown, there are two groups of opposite groups in the multiple disconnected parts 1221, and the axis directions of the disconnected parts 1221 in different opposite groups are different. Therefore, for the temperature sensing package 3, it can be installed in the forward or reverse direction in two different linear directions; in addition, as shown in the accompanying drawings Figure 7 and Figure 8 As shown, two temperature sensing packages 3 are simultaneously installed in the assembly groove 13 to meet different needs. Of course, as needed, more than two groups of opposing groups formed by the disconnected portions 1221 facing each other can also be provided.

[0059] Furthermore, a notch 4 is provided on the protrusion 122 and / or the blocking piece 111 . The notch 4 is connected to the assembly groove 13 . The notch 4 is configured to dissipate heat for the temperature sensing package 3 in the assembly groove 13 .

[0060] Specifically, as shown in the accompanying drawings Figure 10 and Figure 11 As shown, the protrusion 122 and / or the baffle 111 may be provided with some notches 4. The notches 4 are equivalent to forming some hollow structures on the protrusion 122 and / or the baffle 111 that are connected to the assembly groove 13. These hollow structures can serve as heat dissipation channels to dissipate heat from the temperature sensing package 3 inside the assembly groove 13. The hollow structures can also reduce the corresponding material consumption to a certain extent.

[0061] It should be noted that, based on the disconnected portion 1221 formed on the aforementioned protrusion 122 , the fracture at the disconnected portion 1221 can actually serve as a heat dissipation channel to a certain extent, especially when the fracture at some disconnected portion 1221 is not equipped with a temperature sensing package 3 .

[0062] Example 2

[0063] An embodiment of the present invention provides an end cover assembly 1, which is configured to be mounted on a top cover 2 of a compressor. A bottom portion of the end cover assembly 1 in contact with the top cover 2 is configured with an assembly groove 13, and the assembly groove 13 is formed with a notch on the bottom surface of the end cover assembly 1.

[0064] The assembly groove 13 is configured to form an assembly cavity together with the top cover 2 for accommodating the temperature sensing package 3 , and the notch is configured to allow the temperature sensing package 3 in the assembly cavity to contact the top cover 2 .

[0065] Specifically, the present invention designs the structure of the end cap assembly 1 and integrates the installation structure of the temperature sensing package 3 into the end cap assembly 1, thus solving the problems of the prior art. Figure 1 and Figure 2 As shown, the bottom of the end cover assembly 1 is constructed with an assembly groove 13, and the notch of the assembly groove 13 is located on the bottom surface of the end cover assembly 1. When the end cover assembly 1 is installed on the top cover of the compressor, the bottom surface of the end cover assembly 1 is in contact with the surface of the top cover, and the top cover also closes the notch of the assembly groove 13, so that the top cover and the assembly groove 13 together form a cavity, that is, an assembly cavity for the temperature sensing package 3 to be installed. The temperature sensing package 3 installed in the assembly cavity can have its bottom contact with the surface of the top cover through the notch of the assembly groove 13, and then the temperature sensing package 3 can directly detect the temperature inside the compressor through the top cover of the compressor housing, thereby ensuring the accuracy of temperature detection.

[0066] Furthermore, the end cover assembly 1 includes an end cover body 11 and an insulating pad 12 arranged at the bottom of the end cover body 11. The insulating pad 12 is constructed with an assembly opening 121 that penetrates the upper insulating pad 12 in the thickness direction. The end cover body 11 is constructed with a baffle 111 that corresponds to the assembly opening 121 and covers the assembly opening 121. The baffle 111 and the assembly opening 121 together form an assembly groove 13.

[0067] Specifically, as shown in the accompanying drawings Figure 2 and Figure 3 As shown, the end cap assembly 1 adopts a split structure to form the installation structure of the temperature sensing bulb 3. The insulating gasket 12 of the end cap assembly 1 is installed at the bottom of the end cap body 11. The assembly groove 13 of the end cap assembly 1 is formed by the assembly opening 121 on the insulating gasket 12 and the blocking piece 111 of the end cap body 11. The assembly opening 121 serves as the main body of the assembly groove 13. When the end cap body 11 and the insulating gasket 12 are assembled, the blocking piece 111 on the end cap body 11 corresponds to the upper part of the assembly opening 121 and covers the assembly opening 121, thereby forming the assembly groove 13.

[0068] In this embodiment, the end cap assembly 1 adopts a split structure to form the mounting structure of the temperature-sensing bulb 3, which can effectively reduce the deformation and stress of the temperature-sensing bulb 3. The principle is that the split structure has a certain assembly gap between each other, which can cope with the deformation caused by the high temperature during operation of the compressor and achieve a buffering effect on the deformation, thereby avoiding causing excessive deformation of the temperature-sensing bulb 3 installed therein, and further avoiding the problem of stress concentration in the temperature-sensing bulb 3. In addition, the end cap body 11 of this embodiment is made of a hard material, and the insulating pad 12 is made of a soft material, further ensuring that the deformation and stress of the temperature-sensing bulb 3 are effectively reduced.

[0069] The deformation and stress simulation results of the split structure adopted by the end cover assembly 1 of this embodiment are shown in the attached figure Figure 14 and Figure 15 In addition, under the same external force (10N in this embodiment), the deformation and stress simulation results of the split structure and the integral structure are compared as shown in the following table. The deformation is reduced by 6% and the stress is reduced by 22%, indicating that the split structure of this embodiment can effectively improve the deformation and stress of the temperature sensing package 33.

[0070] Integrated structure Split structure Difference ratio Maximum deformation (mm) 0.00408 0.00385 0.00023 ↓6％ Maximum stress (MPa) 6.0367 4.7313 1.3054 ↓22％

[0071] Furthermore, a protrusion 122 is constructed on the first surface of the insulating gasket 12 close to the end cover body 11, and the protrusion 122 is located at the edge of the assembly opening 121 and extends along the edge of the assembly opening 121; wherein the baffle 111 is constructed to cover the top of the protrusion 122 to form an assembly groove 13.

[0072] Specifically, as shown in the accompanying drawings Figure 2 and Figure 3 As shown, a protrusion 122 is formed on the surface of the insulating gasket 12, and the protrusion 122 is located at the edge of the assembly opening 121. With respect to the assembly groove 13, the inner wall of the assembly opening 121 and the inner wall of the protrusion 122 together form the groove wall of the assembly groove 13. The purpose of providing the protrusion 122 is to appropriately reduce the overall thickness of the insulating gasket 12 while ensuring the depth of the assembly groove 13, thereby reducing the material used for the end cap assembly 1 and reducing the cost.

[0073] Optionally, the protrusion 122 extends continuously or discontinuously along the edge of the assembly opening 121; wherein, the protrusion 122 that extends discontinuously along the edge of the assembly opening 121 is constructed with at least one disconnecting portion 1221 in its extension direction, and the disconnecting portion 1221 is constructed with a fracture for allowing the temperature sensing package 3 to enter and exit the assembly groove 13.

[0074] Specifically, as needed, the protrusion 122 can be continuously extended along the edge of the assembly opening 121 to surround a circle, or it can be discontinuously extended to form multiple disconnected portions 1221 at discontinuous positions. In this embodiment, it is preferred that the protrusion 122 be discontinuously extended along the edge of the assembly opening 121, as shown in the accompanying drawings. Figure 3 As shown, the formed disconnecting portion 1221 forms a break on the colored pen of the assembly groove 13 , which allows the temperature sensing package 3 to be loaded into or unloaded from the assembly groove 13 , thereby facilitating the installation of the temperature sensing package 3 .

[0075] Furthermore, the protrusion 122 is constructed with a plurality of disconnected portions 1221 in its extending direction. The disconnected portions 1221 have a plurality of different orientations, so that one or more temperature sensing packages 3 can be installed into the assembly groove 13 from different directions.

[0076] Specifically, as shown in the accompanying drawings Figure 3 Shown with Figure 8 As shown, the discontinuously extended protrusion 122 has a plurality of disconnected portions 1221, and the plurality of disconnected portions 1221 form a plurality of fractures on the groove wall of the assembly groove 13. The plurality of fractures have different orientations, so the temperature sensing package 3 can be installed into the assembly groove 13 from different disconnected portions 1221, and thus the installation direction of the temperature sensing package 3 also has a plurality of options to meet different needs.

[0077] Optionally, the plurality of disconnecting portions 1221 include at least one pair of disconnecting portions 1221 opposite to each other, and the axes of the disconnecting portions of the pair of disconnecting portions 1221 opposite to each other are collinear.

[0078] Specifically, as shown in the accompanying drawings Figure 3 As shown, a pair of the disconnected portions 1221 are opposite to each other, so that the temperature sensing package 3 can be installed into the assembly groove 13 from two completely opposite directions, as shown in the accompanying drawings. Figure 3 and Figure 4 As shown in the attached figure Figure 7 and Figure 8 As shown, there are two pairs of disconnected portions 1221 facing each other in the plurality of disconnected portions 1221, and the axis directions of the disconnected portions of each pair of disconnected portions 1221 are different. Therefore, for the temperature sensing package 3, it can be installed in the forward or reverse direction in two different linear directions; in addition, as shown in the accompanying drawings Figure 7 and Figure 8 As shown, two temperature sensing packages 3 are simultaneously installed in the assembly groove 13 to meet different needs. Of course, more than two pairs of disconnecting portions 1221 facing each other can be provided as needed.

[0079] In addition, as shown in the attached figure Figure 12 and Figure 13As shown, when the end cover assembly 1 is installed on the top cover 2 of the compressor, at different installation angles a (installation angle a is the angle between the line connecting the center of the compressor liquid reservoir 5 and the center of the top cover 2 and the line connecting the center of the terminal of the end cover body 11 and the center of the top cover 2), the protrusion 122 has multiple disconnecting portions 1221 with different directions, which can further meet the installation needs of the temperature sensing package 3 in different directions.

[0080] Furthermore, a notch 4 is provided on the protrusion 122 and / or the blocking piece 111 . The notch 4 is connected to the assembly groove 13 . The notch 4 is configured to dissipate heat for the temperature sensing package 3 in the assembly groove 13 .

[0081] Specifically, as shown in the accompanying drawings Figure 10 and Figure 11 As shown, the protrusion 122 and / or the baffle 111 may be provided with some notches 4. The notches 4 are equivalent to forming some hollow structures on the protrusion 122 and / or the baffle 111 that are connected to the assembly groove 13. These hollow structures can serve as heat dissipation channels to dissipate heat from the temperature sensing package 3 inside the assembly groove 13. The hollow structures can also reduce the corresponding material consumption to a certain extent.

[0082] It should be noted that, based on the disconnected portion 1221 formed on the aforementioned protrusion 122 , the fracture at the disconnected portion 1221 can actually serve as a heat dissipation channel to a certain extent, especially when the fracture at some disconnected portion 1221 is not equipped with a temperature sensing package 3 .

[0083] Furthermore, the baffle 111 is constructed on the outer surface of the end cover body 11, and the end cover body 11 is adjacent to the first side of the assembly opening 121 when the baffle 111 corresponds to the assembly opening 121, and the protrusion 122 is constructed at the edge of the assembly opening 121 on other sides except the first side.

[0084] Specifically, as shown in the accompanying drawings Figure 5 As shown, the baffle 111 is arranged on the outer surface of the end cover body 11 and has a certain distance from the bottom of the end cover body 11, so that after the end cover body 11 and the insulating pad 12 are assembled, the outer wall of the end cover body 11 (specifically the part of the outer wall between the baffle 111 and the bottom of the end cover body 11) can be directly used as the groove wall of the first side of the assembly groove 13, and then the end cover body 11 can be functionally referred to as the protrusion 122 on the first side of the assembly groove 13, so the protrusion 122 can be not provided on the first side of the assembly groove 13 (that is, the assembly opening 121), which simplifies the structure while increasing the area of the heat dissipation channel of the assembly groove 13. Because the length of the assembly groove 13 is greater than the width of the end cover body 11, the end cover body 11 can only serve as a partial groove wall on the first side of the assembly groove 13, so that the first side of the assembly groove 13 also has an open part, which can be used for heat dissipation.

[0085] Furthermore, the length L of the assembly groove 13 and the length L1 of the wall of the assembly groove 13 (specifically the wall of the solid part) in the same direction satisfy the relationship: 1≤L / L1≤2; the temperature sensing package 3 is constructed as a cylindrical structure, and the axial length L2 and diameter d1 of the temperature sensing package 3 and the length L and width d of the assembly groove 13 satisfy the relationship: L / L2=0.8d1 / d.
