DETAILED DESCRIPTION

[0057] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0058] like Figures 1 to 9 According to the compressor 100 of the embodiment of the present invention, the compressor 100 includes an upper shell 11 and a terminal assembly 12. The terminal assembly 12 includes a first connecting seat 121a, a second connecting seat 121b, a wiring terminal 124, a temperature sensor 122 and a sealing gasket 123. The first connecting seat 121a is used to position the temperature sensor 122 to the upper shell 11. When the first connecting seat 121a is connected to the upper shell 11, the second connecting seat 121b can be positioned to the upper shell 11 by utilizing the matching structure between the second connecting seat 121b and the first connecting seat 121a. The upper shell 11 can be provided with a wiring structure, and the wiring structure can be connected to the wiring terminal 124, so as to realize power supply to the compressor 100, etc. The temperature sensor 122 is used to detect the temperature of the upper shell 11. The sealing gasket 123 is used to protect the temperature sensor 122, realize waterproof and dustproof properties of the temperature sensor 122, and improve detection accuracy, etc.

[0059] Among them, the first connecting seat 121a and the second connecting seat 121b are split structures, and the first connecting seat 121a is connected to the upper shell 11, so that the second connecting seat 121b and the first connecting seat 121a can be formed separately. When the second connecting seat 121b and the first connecting seat 121a are installed to the upper shell 11, the second connecting seat 121b can be installed to the upper shell 11 by utilizing the cooperation between the first connecting seat 121a and the upper shell 11, which can simplify the assembly structure of the terminal assembly 12 and the upper shell 11.

[0060] The connection terminal 124 is arranged in the second connection seat 121b. By arranging the connection terminal 124 in the second connection seat 121b, the connection terminal 124 can be waterproof and dustproof, and the stability and safety of the connection terminal 124 can be improved. The temperature sensor 122 is arranged in the first connection seat 121a, and is used to detect the temperature of the upper shell 11. The sealing gasket 123 is arranged between the second connection seat 121b and the upper shell 11 and between the first connection seat 121a and the upper shell 11, wherein the sealing gasket 123 may include a first support portion 1231 and a second support portion 1232, the first support portion 1231 can be arranged between the first connection seat 121a and the upper shell 11 to achieve sealing between the first connection seat 121a and the upper shell 11; the second support portion 1232 can be arranged between the second connection seat 121b and the upper shell 11 to achieve sealing between the second connection seat 121b and the upper shell 11.

[0061] According to the compressor 100 of the embodiment of the present invention, the first matching portion 1211a and the second matching portion 1211b are matched to achieve rapid installation of the first connecting seat 121a and the second connecting seat 121b.

[0062] like Figures 17 to 19 The upper housing 11 also includes a terminal 114, combined with Figure 4 and Figure 12 The second connection base 121b is provided with a socket 1217 opposite to the terminal 124, and the terminal 114 is connected to the terminal 124 through the socket 1217. The second connection base 121b is provided with a socket 1217 opposite to the terminal 124, and the terminal 114 is connected to the terminal 124 through the socket 1217, which can facilitate the electrical connection between the terminal 114 and the terminal 124.

[0063] like Figure 5In some embodiments of the present invention, the first connection base 121a is connected to the upper housing 11. The first connection base 121a abuts the second connection base 121b in a direction toward the upper housing 11, and restricts the second connection base 121b from detaching from the upper housing 11 in a direction away from the upper housing 11. The first connection base 121a is detachable from the upper housing 11 in a direction away from the upper housing 11 and is independently removable relative to the second connection base 121b. The first connection base 121a is independently removable relative to the second connection base 121b. In other words, after the terminal assembly 12 is installed in the upper housing 11, the first connection base 121a can be separated from the second connection base 121b and removed from the upper housing 11 while maintaining the connection between the second connection base 121b and the upper housing 11. This arrangement allows the independent removal of the first connection base 121a, preventing the connection between the second connection base 121b and the upper housing 11 from being affected when removing or replacing the temperature sensor 122. When the temperature sensor 122 needs to be replaced, the temperature sensor 122 can be quickly replaced by simply removing the first connecting seat 121 a , thereby avoiding damage to the glass body of the connection terminal 124 caused by removing the second connecting seat 121 b .

[0064] In addition, if Figures 17 to 19 , the upper housing 11 may be provided with a terminal 114, such as Figure 4 The second connecting seat 121b can be provided with a socket 1217 corresponding to the terminal 114. In order to improve the sealing performance of the upper shell 11, a mounting hole is usually provided in the upper shell 11, and the terminal 114 is passed through the mounting hole, and the mounting hole is sealed with a structure such as a glass body, thereby achieving sealing of the upper shell 11. However, repeated disassembly and assembly of the second connecting seat 121b and the terminal 114 will affect the glass body, causing damage to the glass body or failure of the seal. Therefore, in the present invention, under working conditions such as replacement or maintenance of the temperature sensor 122, when the second connecting seat 112 needs to be disassembled, the first connecting seat 121a can be disassembled independently of the second connecting seat 121b, thereby reducing the impact on the second connecting seat 121b, the terminal 114, and the glass body, and improving the stability and service life of the compressor 100.

[0065] The assembly method of the terminal assembly 12 and the upper shell 11 in the present invention may include but is not limited to: method one, assembling the second connecting seat 121b and the first connecting seat 121a and then installing them to the upper shell 11; method two, pre-positioning the second connecting seat 121b on the upper shell 11, connecting the first connecting seat 121a to the upper shell 11, and utilizing the cooperation of the second matching portion 1211b and the first matching portion 1211a to realize the assembly of the second connecting seat 121b and the upper shell 11; method three, installing the second connecting seat 121b and the first connecting seat 121a to the upper shell 11 at the same time, and utilizing the cooperation of the second matching portion 1211b and the first matching portion 1211a to complete the assembly of the second connecting seat 121b and the upper shell 11, and the assembly of the first connecting seat 121a and the upper shell 11, etc.

[0066] The disassembly methods of the terminal assembly 12 and the upper shell 11 in the present invention may include but are not limited to: method one, after separating the second mating portion 1211b and the first mating portion 1211a, the second connecting seat 121b and / or the first connecting seat 121a are disassembled from the upper shell 11; method two, after disassembling the terminal assembly 12 from the upper shell 11, the second connecting seat 121b and the first connecting seat 121a are separated; method three, when only the first connecting seat 121a needs to be disassembled, the first connecting seat 121a can be separated from the upper shell 11 and the second connecting seat 121b. If the second connecting seat 121b needs to be disassembled, the first connecting seat 121a can be disassembled from the upper shell 11 after the first connecting seat 121a is separated from the upper shell 11.

[0067] Of course, the above descriptions of the assembly and disassembly methods of the terminal assembly 12 and the upper shell 11 are merely some implementation methods of the present invention and are not intended to limit the scope of protection of the present invention.

[0068] The first connecting base 121a can be separated from the second connecting base 121b in a vertical direction (referring to the bottom-up direction in the accompanying drawings), where the vertical direction can be a direction perpendicular to and away from the upper shell 11; or the first connecting base 121a can be separated from the second connecting base 121b in a parallel direction (referring to the left-to-right direction in the accompanying drawings), where the parallel direction can be a direction parallel to the upper shell 11; or the first connecting base 121a can be separated from the second connecting base 121b in a direction that forms an acute angle with the vertical direction and the parallel direction, etc. The above-mentioned separation method of the second connecting base 121b from the first connecting base 121a allows the first connecting base 121a to be removed from the upper shell 11 without affecting the mating structure between the second connecting base 121b and the upper shell 11.

[0069] like Figure 3 as well as Figures 10 to 16In some embodiments, the first connecting base 121a includes a first mating portion 1211a, and the second connecting base 121b includes a second mating portion 1211b. The first mating portion 1211a and the second mating portion 1211b cooperate to position the second connecting base 121b on the upper housing 11. The second mating portion 1211b can be nested with the first mating portion 1211a, including but not limited to the following: the second mating portion 1211b is nested within the first mating portion 1211a; or the first mating portion 1211a is nested within the second mating portion 1211b; or a portion of the second mating portion 1211b is nested within the first mating portion 1211a, and a portion of the first mating portion 1211a is nested within the second mating portion 1211b. By utilizing the nested connection structure of the second mating portion 1211b and the first mating portion 1211a, the second mating portion 1211b and the first mating portion 1211a can be quickly installed and disassembled, thereby improving the installation and disassembly efficiency of the terminal assembly 12.

[0070] In addition, the second matching portion 1211b and the first matching portion 1211a are separable, wherein the direction of separation of the first matching portion 1211a and the second matching portion 1211b can be the aforementioned vertical direction, parallel direction, or a direction having an acute angle with the vertical direction or the parallel direction.

[0071] like Figure 1 and Figure 2 The first connecting seat 121a and the upper shell 11 are distributed along the first direction (refer to the up and down direction in the drawings), and are combined Figures 10 to 16 The second mating portion 1211b includes a mating cavity 1212b and a positioning portion 1214b. The positioning portion 1214b is opposite to the mating cavity 1212b along a first direction. The first mating portion 1211a includes a mating block 1212a. The mating block 1212a is disposed in the mating cavity 1212b and is located on the side of the positioning portion 1214b facing away from the upper housing 11. During assembly of the second mating portion 1211b and the first mating portion 1211a, the mating block 1212a can be nested within the mounting cavity along the first direction. The mating block 1212a can then be used to limit the positioning portion 1214b, preventing the second mating portion 1211b from being dislodged.

[0072] like Figure 15 The mating cavity 1212b extends along the first direction and is open to the side of the upper housing 11 in the first direction. The mating block 1212a is slidable in the first direction and can slide into and out of the open opening of the mating cavity 1212b. In this way, the mating block 1212a can slide into and out of the mating cavity 1212b without affecting the connection structure between the second connecting base 121b and the upper housing 11, thereby improving the efficiency of assembly and disassembly of the second connecting base 121b and the first connecting base 121a.

[0073] like Figure 3 and Figure 4 , the second connecting seat 121b and the first connecting seat 121a are distributed along the second direction, such as Figure 15 The second matching portion 1211b further includes a limiting sliding groove 1213b provided on the side wall of the matching cavity 1212b along the third direction. Figure 13 and Figure 14 The first mating portion 1211a further includes a limiting slider 1213a disposed on the mating block 1212a and corresponding to the limiting slot 1213b. The limiting slider 1213a is slidably disposed in the limiting slot 1213b along a first direction and limits the second connecting seat 121b from separating from the first connecting seat 121a along a second direction. The first direction, the second direction, and the third direction are perpendicular to each other. By providing the limiting slot 1213b and the limiting slider 1213a, the second connecting seat 121b and the first connecting seat 121a can be limited in the second direction, and the second connecting seat 121b can be stably mounted to the upper housing 11 using the first connecting seat 121a, thereby improving the assembly efficiency of the terminal assembly 12 in the upper housing 11.

[0074] Among them, the first direction can be a direction perpendicular to the upper shell 11, refer to the up and down direction in the accompanying drawing; the second direction can be a direction parallel to the upper shell 11, refer to the left and right direction in the accompanying drawing; the third direction can be a direction parallel to the upper shell 11, refer to the front and back direction in the accompanying drawing.

[0075] Combine Figure 14 and Figure 16The dimension of the limiting slider 1213a along the second direction is L1, the dimension of the matching block 1212a along the second direction is L2, the dimension of the limiting slot 1213b along the second direction is L3, the dimension of the matching cavity 1212b along the second direction is L4, the total dimension of the matching block 1212a and the limiting slider 1213a along the third direction is L5, and the total dimension of the matching cavity 1212b and the limiting slot 1213b along the third direction is L6. The dimension value of the mating block 1212a along the third direction is L7. The mating block 1212a is provided with a mating hole 1211. The diameter dimension value of the mating hole 1211 is D2, wherein 0.15<L1 / L2<0.5; and / or, 0.18<L3 / L4<0.83; and / or, 0.8<L1 / L3<0.97; and / or, 0.925<L5 / L6<0.99; and / or, 1.1<L7 / D2<2.0. The problem of difficulty in assembling the first mating portion 1211a and the second mating portion 1211b due to production errors is avoided, and the first mating portion 1211a and the second mating portion 1211b can be ensured to have sufficient mating strength so that the first mating portion 1211a and the second mating portion 1211b can be stably assembled along the second direction. The mating position of the first connecting seat 121a and the second connecting seat 121b can be ensured to have sufficient strength and be easy to install, and the first connecting seat 121a can be easily installed and disassembled independently relative to the second connecting seat 121b.

[0076] like Figures 17 to 20 The upper housing 11 includes a flat portion 111 and a connecting post 112. The flat portion 111 can be configured to have a flat surface. The connecting post 112 is configured to position the terminal assembly 12 to the upper housing 11. Figures 3 to 9 , the first connecting seat 121a is provided with a matching hole 1211, and the connecting column 112 is passed through the matching hole 1211 and positions the first connecting seat 121a on the upper shell 11, wherein one end of the connecting column 112 can be fixedly connected to the shell body of the upper shell 11 and extends in a direction substantially perpendicular to the shell body of the upper shell 11. When installing the first connecting seat 121a to the upper shell 11, the connecting column 112 can be aligned with the matching hole 1211, and the first connecting seat 121a can be driven to move toward the upper shell 11; after the upper shell 11 is moved into place, the locking nut 13 and other positioning parts are used to connect with the connecting column 112, and the first connecting seat 121a is locked and positioned on the upper shell 11. The temperature sensor 122 is provided on the first connecting seat 121a, such as Figure 21 and Figure 22The temperature sensor 122 has a temperature sensing surface 1221, which can cooperate with the flat portion 111 for the temperature sensor 122 to detect the temperature of the upper shell 11, wherein the temperature sensing surface 1221 can be in surface contact with the flat portion 111, that is, at least a portion of the temperature sensing surface 1221 is in contact with the flat portion 111. The sealing gasket 123 includes a first support portion 1231, which is provided between the first connecting seat 121a and the upper shell 11. The first support portion 1231 surrounds the temperature sensor 122, and the first support portion 1231 can achieve waterproof and dustproof properties for the temperature sensor 122, preventing impurities such as dust and water from entering the vicinity of the temperature sensing surface 1221 and affecting the detection accuracy of the temperature sensor 122, thereby extending the service life of the temperature sensor 122 and improving the detection accuracy of the temperature sensor 122.

[0077] A flat portion 111 is provided on the upper housing 11, and is configured to form a surface-to-surface contact with a temperature-sensing surface 1221 of a temperature sensor 122. This optimizes the heat conduction between the temperature sensor 122 and the upper housing 11, thereby improving the accuracy of the temperature sensing of the upper housing 11 by the temperature sensor 122 and facilitating control of the compressor 100. Furthermore, a sealing gasket 123 is provided to protect the temperature sensor 122 from water and dust, preventing impurities such as water from entering the vicinity of the temperature sensor 122 and affecting the temperature sensing of the upper housing 11 by the temperature sensor 122, thereby further improving the accuracy of the temperature sensing of the upper housing 11.

[0078] Compressor 100 Figure 1 After assembly, the surface of the upper shell 11 is rough, and the deformation of the sealing gasket 123 plays a sealing role, so that the waterproof and dustproof level of the terminal assembly 12 can reach IP54.

[0079] The upper shell 11 of the compressor 100 is typically an arc-shaped shell. The outer side of the upper shell 11 may have an arcuate surface and a flat portion 111. The flat portion 111 may be configured to be raised relative to the arcuate surface and to form a planar structure. Furthermore, a first connecting seat 121a may be provided on the flat portion 111 of the upper shell 11 and secured to the upper shell 11 via a locking nut 13 or the like. Furthermore, the first connecting seat 121a may be provided with a mounting groove 1212, and at least a portion of the temperature sensor 122 may be disposed in the mounting groove 1212.

[0080] In the present invention, the first and second connecting seats 121a, 121b are configured as separate structures and locked using connecting posts 112. The fixing member (i.e., the locking nut 13 described below) connected to the connecting posts 112 exerts uneven pre-tightening force on the first and second connecting seats 121a, 121b, causing them to be compressed and deformed. This deformation of the first and second connecting seats 121a, 121b reduces the sealing effect. To ensure that this deformation does not affect the sealing effect, the present invention provides a compensating structure on the surfaces of the first and second connecting seats 121a, 121b opposite the flat portion 111. This includes, but is not limited to, the following embodiments and their combinations.

[0081] Implementation Method 1 like Figure 27 , and combined with Figure 2 and Figure 17 The first connecting seat 121a has a first mating surface opposite the flat portion 111. The first mating surface is inclined at a first predetermined angle x1 relative to a set plane toward the upper housing 11 in a direction away from the mating hole 1211. The set plane is perpendicular to the axis of the mating hole 1211. By configuring the first mating surface in an inclined manner, the first support portion 1231 can be more evenly deformed when the first connecting seat 121a is positioned using the connecting post 112, thereby achieving uniform deformation of the first support portion 1231 and improving the sealing effect between the first connecting seat 121a and the upper housing 11.

[0082] Optionally, the end of the connecting column 112 is connected to the locking nut 13, and the locking torque of the locking nut 13 is T1. The diameter size of the connecting column 112 is D3. The contact area between the locking nut 13 and the first connecting seat 121a is S3. The distance between the locking nut 13 and the flat portion 111 is H, the elastic modulus of the first connecting seat 121a is E, the maximum distance between the first connecting seat 121a and the axis of the matching hole 1211 is Y1, and the first predetermined angle x1 satisfies: 0<x1≤2×arctan(T1 / (k×D3×S3×H×E×Y1)), where k is the torque coefficient, which can be 0.2≤k≤0.3. Specifically, the locking pressure of the locking nut 13 is F=T1 / (k×D3), the stress σ1=F / S=T1(k×D3×S3), and the strain ε=σ1 / E. The maximum deformation of the first connecting seat 121a is x3=ε×H=(σ1 / E)×H=T1 / (k×D3×S3×E) (refer to Figure 27The figure shown in the middle circle G1 is the deformation of the first mating surface at different positions of the first connecting seat 121a when the first mating surface is perpendicular to the axis of the mating hole 1211). It can be concluded that when the first predetermined angle x1 is set to x1=arctan(x3 / Y1)=arctan(T1 / (k×d×S3×H×E×Y1)), the first connecting seat 121a has a better sealing effect. According to actual detection and analysis, the first predetermined angle x1 and the uniformity of the deformation of the first support portion 1231 gradually increase from 0 to arctan(T1 / (k×d×S3×H×E×Y1) and then gradually decrease. When 0<x1≤2×arctan(T1 / (k×D3×S3×H×E×Y1)), the first support portion can achieve a better sealing effect. Therefore, the above-mentioned setting of the present invention can improve the uniformity of the deformation and the sealing performance of the first support portion.

[0083] Optionally, the first predetermined angle x1 may be set to 0.05°≤x1≤2.5°. For example, x1 may be set to 0.05°, 0.1°, 0.15°, 0.3°, 0.5°, 1.6°, 2°, or 2.5°, etc., which can improve the uniformity of the deformation of the sealing gasket and the sealing performance.

[0084] Implementation Method 2 like Figure 28 , and combined with Figure 2 and Figure 17 The second connecting seat 121b has a second mating surface opposite the flat portion 111. The second mating surface is inclined at a second predetermined angle x2 relative to a set plane toward the upper housing 11 in a direction away from the mating hole 1211. The set plane is perpendicular to the axis of the mating hole 1211. By configuring the second mating surface in an inclined manner, the second support portion 1232 can be more evenly deformed when the second connecting seat 121a is positioned using the connecting post 112, thereby achieving uniform deformation of the second support portion 1232 and improving the sealing effect between the second connecting seat 121a and the upper housing 11.

[0085] Optionally, the end of the connecting column 112 is connected to the locking nut 13, and the locking torque of the locking nut 13 is T1. The diameter size of the connecting column 112 is D3. The contact area between the locking nut 13 and the first connecting seat 121a is S3. The distance between the locking nut 13 and the flat portion 111 is H, the elastic modulus of the second connecting seat 121b is E, the maximum distance between the second connecting seat 121b and the axis of the matching hole 1211 is Y2, and the second predetermined angle x2 satisfies: 0<x2≤2×arctan(T1 / (k×D3×S3×H×E×Y2)), where k is the torque coefficient, which can be 0.2≤k≤0.3. Specifically, the locking pressure of the locking nut 13 is F=T1 / (k×D3), the stress σ1=F / S3=T1(k×D3×S3), and the strain ε=σ1 / E. The maximum deformation of the second connecting seat 121a is x4=ε×H=(σ1 / E)×H=T1 / (k×D3×S3×E) (see Figure 28 The figure shown in the middle circle G2 shows the deformation of the second mating surface at different positions of the second connecting seat 121b when the second mating surface is perpendicular to the axis of the mating hole 1211, where the second predetermined angle can be set to x2=arctan(x4 / Y2)=arctan(T1 / (k×d×S3×H×E×Y2). The sealing performance can be improved.

[0086] Optionally, the second predetermined angle x2 may be set to 0.05°≤x2≤2.5°. For example, x2 may be set to 0.05°, 0.1°, 0.15°, 0.3°, 0.5°, 1.6°, 2°, or 2.5°, etc., which can improve the uniformity of the deformation of the sealing gasket and the sealing performance.

[0087] In addition, the second connecting seat 121 b may have a hole corresponding to the matching hole 1211 , and the connecting column 112 may pass through the hole and the matching hole and then be connected to the locking nut 13 .

[0088] The present invention provides some application cases as follows, which of course do not limit the scope of protection of the present invention.

[0089] Case 1: The tightening torque of the locking nut 13 is 1.2 Nm, the diameter D3 of the connecting column 112 is 6 mm, and the first connecting seat 121a and the second connecting seat 121b are made of PBT material with an elastic modulus E=2.5×10 9 N / m 2 , where Y1=31mm, Y2=44mm, H=32.2mm, F=1.2 / (0.25×0.006)=800N, and the contact area S3 between the locking nut 13 and the first connecting seat 121a is 84.78mm 2 , σ1=F / A=9.44×10 6 N / m 2, strain ε=σ1 / E=3.78×10 -3 , the deformation x3=x4=ε×H=0.12mm, it can be concluded that x1=arctan0.12 / 31=0.22°; x2=arctan0.12 / 44=0.16°.

[0090] Case 2: The tightening torque of the locking nut 13 is 2.0 Nm, the diameter D3 of the connecting column 112 is 6 mm, and the first connecting seat 121a and the second connecting seat 121b are made of PBT material with an elastic modulus E=2.5×10 9 N / m 2 , where Y1=31mm, Y2=44mm, H=32.2mm, F=2.0 / (0.25×0.006)=1333N, and the contact area S3 between the locking nut 13 and the first connecting seat 121a is 84.78mm 2 , σ1=F / A=15.7×10 6 N / m 2 , strain ε=σ1 / E=6.28×10 -3 , the deformation x3=x4=ε×H=0.20mm, it can be concluded that x1=arctan0.20 / 31=0.37°; x2=arctan0.20 / 44=0.26°.

[0091] Case 3: The tightening torque of the locking nut 13 is 1.2 Nm, the diameter D3 of the connecting column 112 is 6 mm, and the first connecting seat 121a and the second connecting seat 121b are made of PP material with an elastic modulus E=1.8×10 9 N / m 2 , where Y1=31mm, Y2=44mm, H=32.2mm, F=1.2 / (0.25×0.006)=800N, and the contact area S3 between the locking nut 13 and the first connecting seat 121a is 84.78mm 2 , σ1=F / A=9.44×10 6 N / m 2 , strain ε=σ1 / E=5.24×10 -3 , the deformation x3=x4=ε×H=0.17mm, it can be concluded that x1=arctan0.12 / 31=0.31°; x2=arctan0.12 / 44=0.22°.

[0092] like Figure 5 and Figure 6 In some embodiments, the connecting base 121 is provided with a mounting groove 1212 , and at least a portion of the temperature sensor 122 is disposed in the mounting groove 1212 .

[0093] In some embodiments, combined Figure 3、 Figure 4 、 Figure 21 as well as Figure 22 , the ratio of the center distance C1 between the temperature sensor 122 and the matching hole 1211 to the maximum outer diameter D1 of the temperature sensing surface 1221 satisfies: 1<C1 / D1≤1.6, for example, the ratio C1 / D1 can be set to 1.1, 1.25, 1.3, 1.45, 1.5 or 1.6, etc., wherein the center distance C1 between the temperature sensor 122 and the matching hole 1211 refers to the distance between the axis of the temperature sensor 122 and the axis of the matching hole 1211; or the distance between the center of the temperature sensing surface 1221 and the center of the matching hole 1211. The temperature sensor 122 can be stably matched with the flat portion 111 of the upper shell 11, wherein, when the temperature sensing surface 1221 of the temperature sensor 122 is completely fitted with the flat portion 111, the contact area between the temperature sensor 122 and the upper shell 11 can be equal to the area S of the temperature sensing surface 1221, and the temperature sensing effect is optimal at this time. Figure 24 The figure shows a curve showing how the contact area between the temperature sensor and the flat portion changes with C1 / D1. The vertical axis represents the contact area between the temperature sensor and the upper shell, and the horizontal axis represents the ratio C1 / D1. It can be seen that when C1 / D1=2.16, the contact area between the temperature sensor 122 and the flat portion 111 of the upper shell 11 is only S / 2. At this time, the detection accuracy of the temperature sensor 122 is greatly affected. When C1 / D1>2.16, as the ratio C1 / D1 increases, the contact area between the temperature sensor 122 and the flat portion 111 of the upper shell 11 will continue to decrease, affecting the temperature detection of the temperature sensor 122. When C1 / D1≤1, dimensional interference may occur between the temperature sensor 122 and the connecting column 112 of the upper shell 11 in the horizontal direction. In the present invention, 1<C1 / D1≤1.6, there is enough space to set the first support part 1231, thereby improving the sealing performance of the first support part 1231; in addition, the contact area between the temperature sensor 122 and the flat part 111 can be increased, thereby improving the temperature measurement accuracy and stability of the temperature sensor 122.

[0094] In addition, the upper shell 11 can also include an exhaust pipe 113. The upper shell 11 can be roughly configured to be circular. The exhaust pipe 113 can be configured to extend along the axis of the upper shell 11. The temperature sensor 122 and the first connecting seat 121a can be arranged on the side of the exhaust pipe 113.

[0095] In some embodiments, the ratio of the minimum distance C2 (not shown) between the central axis of the temperature sensor 122 and the edge of the flat portion 111 to the maximum outer diameter D1 of the temperature sensing surface 1221 satisfies the following: 0.6 ≤ C2 / D1. For example, C2 / D1 can be set to 0.6, 1.25, 1.3, 1.45, 1.5, or 1.6. This ensures maximum contact area between the temperature sensing surface 1221 and the flat portion 111, effectively improving the detection accuracy of the temperature sensor 122. Furthermore, the first support portion 1231 can cooperate with the flat portion 111 to enhance sealing, further improving the detection accuracy of the temperature sensor 122.

[0096] like Figure 17 In some embodiments, the flat portion 111 includes a first side 1111, a second side 1112 and a third side 1113. The first side 1111 and the second side 1112 are arranged on both sides of the central axis of the upper shell 11. The third side 1113 extends along the circumference of the upper shell 11. The two ends of the third side 1113 are connected to the first side 1111 and the second side 1112. The flat portion 111 includes a flat surface surrounded by the first side 1111, the second side 1112 and the third side 1113. The connecting column 112 is arranged on the flat surface, and the temperature sensor 122 is in contact with the flat surface. The flat surface enclosed by the first side 1111, the second side 1112 and the third side 1113 can stably cooperate with the temperature sensor 122, thereby improving the detection accuracy of the temperature sensor 122. The connecting column 112 is arranged on the flat surface, which can improve the stability of the connection between the first connecting seat 121a and the upper shell 11, thereby further improving the detection accuracy of the temperature sensor 122.

[0097] In addition, the compressor is in a high-pressure environment with a typical maximum pressure value of 4.2 MPa. The purpose of setting the lower recess in the upper shell is mainly to improve the pressure resistance. Through the above setting, it is possible to avoid the area of the flat portion 111 being too large, resulting in a decrease in the strength of the upper shell and failing to meet the reliability requirements of the compressor pressure resistance.

[0098] Alternatively, as Figure 17 The first side 1111 and the second side 1112 can be straight lines extending on either side of the central axis of the upper housing 11, and the third side 1113 can be an arcuate edge centered on the central axis. The distance between the intersection of the first side 1111 and the second side 1112 and the central axis is C3, the radius of the third side 1113 is R1, the radius of the edge of the upper housing 11 is R2, the distance between the axis of the connecting post 112 and the central axis is C4, and the angle between the first side 1111 and the second side 1112 is a.

[0099] Among them, 0.7≤R1 / R2≤1 can be satisfied, the third side 1113 is spaced apart from the edge of the upper shell 11, and a smooth transition can be provided between the flat portion 111 and the edge of the upper shell 11, which facilitates the molding of the upper shell 11 and avoids problems such as stress concentration at the edge of the upper shell 11, thereby improving the structural stability and service life of the upper shell 11. In addition, 0.25≤C3 / R1≤0.6; or, 0.32≤C4 / R1≤0.7; or, 60°≤a≤180° can also be satisfied. An appropriate flat portion 111 can be provided on the upper shell 11 to facilitate the stable cooperation between the connecting seat 121 and the flat portion 111, so as to facilitate the stable installation of the connecting seat 121 on the upper shell 11, improve the detection accuracy of the temperature sensor 122, etc., and further, reduce the material used in the upper shell 11 and reduce costs.

[0100] Optionally, the connection between the first side 1111 and the third side 1113, and the connection between the second side 1112 and the third side 1113, may be arc-shaped. This facilitates the molding of the flat portion 111 and facilitates surface treatment of the flat portion 111 to improve its surface flatness, thereby ensuring a stable fit between the temperature sensor 122 and the flat portion 111. The upper housing 11 may further include an exhaust pipe 113 extending along the axis of the upper housing 11. This facilitates exhaust from the compressor 100 and improves its performance.

[0101] like Figure 5 In some embodiments, the first connecting base 121a is provided with a mounting groove 1212, in which at least a portion of the temperature sensor 122 is disposed. The sealing gasket 123 further includes a raised portion 1233 disposed within the mounting groove 1212 and positioned between the temperature sensor 122 and the first connecting base 121a along the axis of the temperature sensor 122. When the first connecting base 121a is mounted on the upper housing 11, the temperature sensor 122 can contact the flat portion 111. However, since it is difficult to ensure that the flat portion 111 is completely flat in actual production and processing, the sealing gasket 123 is required to ensure that the temperature sensor 122 is tightly fitted to the upper housing 11. The raised portion 1233 can be used to elastically stop the temperature sensor 122 and apply a force toward the flat portion 111 to the temperature sensor 122, thereby achieving a stable fit between the temperature sensor 122 and the flat portion 111. In addition, the first support portion 1231 can seal the installation groove 1212, so that dust and other impurities can be prevented from entering the installation groove 1212, thereby optimizing the protection effect of the temperature sensor 122.

[0102] like Figure 5The height dimension of the first support portion 1231 is L1, the height dimension of the raised portion 1233 is L2, the height dimension of the mounting groove 1212 is L3, and the height dimension of the temperature sensor 122 is L4, where L1 + L3 < L2 + L4. The first support portion 1231 and the raised portion 1233 of the sealing gasket 123 are compressed in the height direction. The deformation of the first support portion 1231 in the height direction offsets the installation difference of the temperature sensor 122 caused by the flatness of the flat portion 111 of the upper shell 11. In addition, the compression of the raised portion 1233 of the sealing gasket 123 exerts a downward force on the temperature sensor 122, making the temperature sensor 122 tightly fit with the upper shell 11 in the height direction. Combined with the above-mentioned embodiment where 1 < C1 / D1 ≤ 1.6, sufficient contact between the temperature sensor and the flat portion is ensured in both height and horizontal directions to improve detection accuracy.

[0103] Furthermore, the aforementioned height dimensions L1 of the first support portion 1231 and L2 of the raised portion 1233 refer to the height dimensions of the terminal assembly 12 before installation, or in other words, the height dimensions of the gasket 123 before compression. In the assembled compressor 100, after the terminal assembly 12 is removed from the upper housing, the gasket 123 will partially recover due to elastic deformation. Therefore, the height dimensions of the first support portion 1231 and the raised portion 1233 after removal of the terminal assembly 12 can be approximated to the aforementioned dimension L1, and the height dimensions of the raised portion 1233 can be approximated to the aforementioned dimension L2.

[0104] like Figure 25 This graph shows the temperature sensor's detected temperature as a function of the ratio (L1+L3) / (L2+L4), with T representing the actual temperature of the upper housing. The horizontal axis represents the ratio (L1+L3) / (L2+L4), while the vertical axis represents the temperature sensor's detected temperature, with T representing the actual temperature of the upper housing. As can be seen from the accompanying figure, when the ratio (L1+L3) / (L2+L4) ≥ 1, the temperature sensor's detection accuracy decreases. Furthermore, setting the ratio (L1+L3) / (L2+L4) greater than 0.9 can prevent damage to the sealing gasket 123 due to excessive compression.

[0105] The first connecting seat 121a has a mating surface opposite to the flat portion 111, and the mounting groove 1212 has a stop surface corresponding to the protrusion 1233, and the stop surface abuts the protrusion 1233. The height dimension of the first support portion 1231 refers to the dimension of the first support portion 1231 along a direction parallel to the axis of the temperature sensor 122; or in other words, the height dimension of the first support portion 1231 refers to the height of the first support portion 1231 relative to the mating surface. The height dimension of the protrusion 1233 refers to the dimension of the protrusion 1233 along the axis of the temperature sensor 122. The height dimension of the mounting groove 1212 refers to the depth dimension of the mounting groove 1212; or the height dimension of the mounting groove 1212 refers to the distance between the mating surface and the stop surface. The height dimension of the temperature sensor 122 refers to the dimension of the temperature sensor 122 along its axis, or in other words, the distance from the temperature sensing surface 1221 to the surface where the temperature sensor 122 abuts against the protrusion 1233.

[0106] like Figure 6 and Figure 23 In some embodiments, the first connecting seat 121a has a first positioning groove 1213 opposite to the flat portion 111, the first positioning groove 1213 is arranged around the temperature sensor 122, and the sealing gasket 123 also includes a first positioning rib 1234, the first positioning rib 1234 is connected to the first support portion 1231, and the first positioning rib 1234 is arranged in the first positioning groove 1213. The first positioning rib 1234 can cooperate with the first positioning groove 1213 to stably connect the first support portion 1231 to the first connecting seat 121a, thereby improving the stability of the connection structure between the sealing gasket 123 and the first connecting seat 121a and preventing the sealing gasket 123 from falling off the first connecting seat 121a. In addition, before the first connecting seat 121a is installed on the upper shell 11, the sealing gasket 123 can be positioned on the first connecting seat 121a, and then the first connecting seat 121a with the sealing gasket 123 installed can be installed on the upper shell 11. This can simplify the assembly process of the compressor 100 and improve the assembly efficiency of the compressor 100. In addition, the first positioning rib 1234 can be arranged to surround the temperature sensor 122. In this way, the gap between the first support portion 1231 and the connecting portion can be better sealed, thereby further improving the sealing performance of the installation groove 1212 and further improving the detection accuracy of the temperature sensor 122.

[0107] like Figure 5 and Figure 23In some embodiments, the first connecting seat 121a further has a first limiting groove 1214 opposite to the flat portion 111, and the first limiting groove 1214 is arranged on the side of the temperature sensor 122.

In addition, before the second connecting seat 121b is installed on the upper shell 11, the sealing gasket 123 can be positioned to the second connecting seat 121b, and then the second connecting seat 121b with the sealing gasket 123 installed can be installed to the upper shell 11. In this way, the assembly process of the compressor 100 can be simplified and the assembly efficiency of the compressor 100 can be improved.

[0119] In some embodiments, the second connector 121b may be made of PBT and / or PA66, and the first connector 121a may be made of PBT and / or PA66. PBT, or polybutylene terephthalate (PBT), is a translucent or opaque, crystalline thermoplastic polyester resin, also known as polytetramethylene terephthalate.

It is insoluble in common solvents, soluble only in solvents such as metacresol. It exhibits high mechanical strength, hardness, and rigidity. It can be used as an engineering plastic, mechanical accessories such as gears and lubricated bearings, and as a replacement for non-ferrous metals in machine housings and automotive engine blades. It can also be used to make synthetic fibers.

[0121] like Figure 26 According to an embodiment of the present invention, the control method for the compressor 100 includes: The resistance value R of the temperature sensor 122 is obtained. When the resistance value R is greater than a first preset value, the compressor 100 is controlled to execute a temperature protection mode. When the resistance value R is less than a second preset value, the compressor 100 is controlled to execute a normal operation mode.

[0122] The first preset value is greater than the second preset value. The temperature protection mode includes disconnecting the power supply to the compressor 100, while the normal operation mode includes connecting the power supply to the compressor 100. When the resistance value R of the temperature sensor 122 reaches the first preset value, the compressor 100 may be overloaded. To further prevent malfunctions, the compressor 100 can be controlled to enter the temperature protection mode. When the resistance value R of the temperature sensor 122 reaches the second preset value, the compressor 100 can resume normal operation. In this case, the operation of the compressor 100 can be controlled. This improves the operational stability of the compressor 100, facilitates timely troubleshooting, controls the compressor 100 to operate within an appropriate range, avoids compressor 100 malfunctions, prevents frequent starts and stops of the compressor 100, and improves the operational stability of the compressor 100.

[0123] Among them, the first preset value can be set to 100Ω, and the second preset value can be set to 1Ω. Specifically, the control method includes: detecting the resistance value R at both ends of the second connecting wire group. When R>100Ω, the temperature protection is triggered and the power supply is disconnected; when R<1Ω, the electronic control is reset and the electronic control can operate normally.
