DETAILED DESCRIPTION

[0059] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present application, and cannot be understood as a limitation of the present application.

[0060] As Figures 1 to 9 , according to the compressor 100 of the embodiment of the present application, the compressor 100 comprises an upper shell 11 and a terminal assembly 12, the terminal assembly 12 comprises 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 for positioning the temperature sensor 122 to the upper shell 11, when the first connecting seat 121a is connected with the upper shell 11, the second connecting seat 121b can be positioned to the upper shell 11 by using 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, the wiring structure can be connected with the wiring terminal 124, so as to realize power supply and the like of the compressor 100, the temperature sensor 122 is used for detecting the temperature of the upper shell 11, the sealing gasket 123 is used for protecting the temperature sensor 122, realizing waterproof, dustproof and improving detection accuracy and the like of the temperature sensor 122.

[0061] The first connecting seat 121a is connected with the upper shell 11, and the separate molding of the second connecting seat 121b and the first connecting seat 121a can be realized. 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 using the cooperation of the first connecting seat 121a and the upper shell 11, and the assembly structure of the terminal assembly 12 and the upper shell 11 can be simplified.

[0062] The wiring terminal 124 is arranged in the second connecting seat 121b. By arranging the wiring terminal 124 in the second connecting seat 121b, the waterproof and dustproof of the wiring terminal 124 can be realized, and the stability and safety of the wiring terminal 124 can be improved. The temperature sensor 122 is arranged in the first connecting seat 121a and is used for detecting the temperature of the upper shell 11. The sealing gasket 123 is arranged between the second connecting seat 121b and the upper shell 11 and between the first connecting seat 121a and the upper shell 11. The sealing gasket 123 can include a first supporting part 1231 and a second supporting part 1232. The first supporting part 1231 can be arranged between the first connecting seat 121a and the upper shell 11 to realize the sealing between the first connecting seat 121a and the upper shell 11. The second supporting part 1232 can be arranged between the second connecting seat 121b and the upper shell 11 to realize the sealing between the second connecting seat 121b and the upper shell 11.

[0063] According to the compressor 100 of the embodiment of the application, the cooperation of the first cooperating part 1211a and the second cooperating part 1211b can realize the quick installation of the first connecting seat 121a and the second connecting seat 121b.

[0064] As shown in FIG. 1, the upper shell 11 further includes a wiring post 114. Figures 17 to 19 The wiring post 114 is arranged in the first connecting seat 121a and is used for electrically connecting with the wiring terminal 124. Figure 4 The second connecting seat 121b is provided with a hole 1217 opposite to the wiring terminal 124, and the wiring post 114 is arranged in the hole 1217 and is opposite to the wiring terminal 124. Figure 12 The second connecting seat 121b is provided with a hole 1217 opposite to the wiring terminal 124, and the wiring post 114 is arranged in the hole 1217 and is opposite to the wiring terminal 124.

[0065] As shown in FIG. 1, the upper shell 11 further includes a wiring post 114. Figure 5In some embodiments of the present application, the first connecting seat 121a is connected to the upper shell 11, and the first connecting seat 121a abuts against the second connecting seat 121b in a direction towards the upper shell 11 and limits the second connecting seat 121b from being separated from the upper shell 11 in a direction away from the upper shell 11; the first connecting seat 121a is separable from the upper shell 11 in a direction away from the upper shell 11 and is independently detachable with respect to the second connecting seat 121b. The first connecting seat 121a is independently detachable with respect to the second connecting seat 121b. That is, after the terminal assembly 12 is installed to the upper shell 11, the first connecting seat 121a can be separated from the second connecting seat 121b and detached from the upper shell 11 while maintaining the connection between the second connecting seat 121b and the upper shell 11. Through this arrangement, the independent detachment of the first connecting seat 121a is achieved, avoiding the influence of the connection between the second connecting seat 121b and the upper shell 11 when the temperature sensor 122 is detached or replaced. When the temperature sensor 122 needs to be replaced, only the first connecting seat 121a needs to be detached to quickly replace the temperature sensor 122, avoiding the damage of the glass body of the terminal 124 caused by detaching the second connecting seat 121b.

[0066] In addition, as Figures 17 to 19 The upper shell 11 can be provided with a terminal post 114, such as Figure 4 The second connecting seat 121b can be provided with a corresponding insertion hole 1217 corresponding to the terminal post 114. In order to improve the sealing performance of the upper shell 11, a mounting hole is usually provided on the upper shell 11, and the terminal post 114 is arranged through the mounting hole, and the mounting hole is closed by a glass body or the like structure, thereby achieving the sealing of the upper shell 11. However, the repeated disassembly of the second connecting seat 121b and the terminal post 114 will affect the glass body, causing damage to the glass body or sealing failure. Therefore, in the present application, the first connecting seat 121a can be detached independently of the second connecting seat 121b in the working condition of replacing or maintaining the temperature sensor 122 and the like, thereby reducing the influence on the second connecting seat 121b and the terminal post 114 and the glass body, improving the stability and service life of the compressor 100.

[0067] The assembling mode of the terminal assembly 12 and the upper shell 11 in the present application can include but is not limited to: mode one, the second connecting seat 121b and the first connecting seat 121a are assembled and then installed to the upper shell 11; mode two, the second connecting seat 121b is pre-positioned to the upper shell 11, the first connecting seat 121a is connected with the upper shell 11, and the assembling of the second connecting seat 121b and the upper shell 11 is realized by the cooperation of the second cooperation part 1211b and the first cooperation part 1211a; mode three, the second connecting seat 121b and the first connecting seat 121a are simultaneously installed to the upper shell 11, and the assembling of the second connecting seat 121b and the upper shell 11 and the assembling of the first connecting seat 121a and the upper shell 11 are completed by the cooperation of the second cooperation part 1211b and the first cooperation part 1211a, etc.

[0068] The disassembling mode of the terminal assembly 12 and the upper shell 11 in the present application can include but is not limited to: mode one, the second cooperation part 1211b and the first cooperation part 1211a are separated, and then the second connecting seat 121b and / or the first connecting seat 121a are disassembled from the upper shell 11; mode two, the terminal assembly 12 is disassembled from the upper shell 11, and then the second connecting seat 121b and the first connecting seat 121a are separated; mode 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, and if the second connecting seat 121b also needs to be disassembled, the first connecting seat 121a is disassembled from the upper shell 11 after the first connecting seat 121a is separated from the upper shell 11.

[0069] Of course, the above description of the assembling and disassembling mode of the terminal assembly 12 and the upper shell 11 is only some implementation modes of the present application, and is not a limitation on the protection scope of the present application.

[0070] The first connecting seat 121a can be separated from the second connecting seat 121b along a vertical direction (referring to the direction from bottom to top in the drawing), which can be a direction perpendicular to and away from the upper shell 11; or the first connecting seat 121a can be separated from the second connecting seat 121b along a parallel direction (referring to the direction from left to right in the drawing), which can be a direction parallel to the upper shell 11; or the first connecting seat 121a can be separated from the second connecting seat 121b along a direction having an acute angle with the vertical direction and the parallel direction, etc. The above separation mode of the second connecting seat 121b and the first connecting seat 121a can disassemble the first connecting seat 121a from the upper shell 11 without affecting the cooperation structure between the second connecting seat 121b and the upper shell 11.

[0071] As Figure 3 And Figures 10 to 16In some embodiments, the first connecting seat 121a comprises a first matching part 1211a, and the second connecting seat 121b comprises a second matching part 1211b. The first matching part 1211a matches with the second matching part 1211b to position the second connecting seat 121b on the upper shell 11. The second matching part 1211b can be connected with the first matching part 1211a in a nested manner, including but not limited to, the second matching part 1211b being nested in the first matching part 1211a; or, the first matching part 1211a being nested in the second matching part 1211b; or, a part of the second matching part 1211b being nested in the first matching part 1211a, and a part of the first matching part 1211a being nested in the second matching part 1211b, etc. By using the nested connection structure of the second matching part 1211b and the first matching part 1211a, the second matching part 1211b and the first matching part 1211a can be quickly installed and disassembled, and the installation and disassembly efficiency of the terminal assembly 12 can be improved.

[0072] In addition, the second matching part 1211b and the first matching part 1211a can be separated. The direction in which the first matching part 1211a is separated from the second matching part 1211b can be the aforementioned vertical direction, the parallel direction, or a direction having an acute angle with the vertical direction and the parallel direction, etc.

[0073] As shown in FIG. 1, Figure 1 and Figure 2 The first connecting seat 121a is distributed along a first direction (referring to the up-down direction in the drawings) with the upper shell 11, in combination with Figures 10 to 16 The second matching part 1211b comprises a matching cavity 1212b and a positioning part 1214b, and the positioning part 1214b is opposite to the matching cavity 1212b along the first direction. The first matching part 1211a comprises a matching block 1212a, which is arranged in the matching cavity 1212b and located at the side of the positioning part 1214b away from the upper shell 11. During the assembly of the second matching part 1211b and the first matching part 1211a, the matching block 1212a can be nested in the installation cavity along the first direction, and the limiting action of the matching block 1212a on the positioning part 1214b can limit the second matching part 1211b from being pulled out.

[0074] As shown in FIG. 1, Figure 15 The matching cavity 1212b extends along the first direction, and the matching cavity 1212b is open at the side away from the upper shell 11 along the first direction. The matching block 1212a is slidable along the first direction and can slide in and out of the opening of the matching cavity 1212b. In this way, the matching block 1212a can be conveniently slid in and out of the matching cavity 1212b without affecting the connection structure between the second connecting seat 121b and the upper shell 11, and the assembly and disassembly efficiency of the second connecting seat 121b and the first connecting seat 121a can be improved.

[0075] As Figure 3 And Figure 4 , the second connecting seat 121b and the first connecting seat 121a are distributed along the second direction, as Figure 15 The second matching part 1211b further comprises a limiting sliding groove 1213b provided on the side wall of the matching cavity 1212b along the third direction. As Figure 13 And Figure 14 The first matching part 1211a further comprises a limiting sliding block 1213a provided on the matching block 1212a and corresponding to the limiting sliding groove 1213b, the limiting sliding block 1213a is slidably provided in the limiting sliding groove 1213b along the first direction, and the second connecting seat 121b and the first connecting seat 121a are limited to separate along the second direction, the first direction, the second direction and the third direction are perpendicular to each other. By setting the limiting sliding groove 1213b and the limiting sliding block 1213a, the limiting of the second connecting seat 121b and the first connecting seat 121a along the second direction can be realized, the second connecting seat 121b is stably installed to the upper shell 11 by the first connecting seat 121a, and the assembly efficiency of the terminal assembly 12 in the upper shell 11 is improved.

[0076] Wherein, the first direction can be perpendicular to the upper shell 11, refer to the up-down direction in the drawings; the second direction can be parallel to the upper shell 11, refer to the left-right direction in the drawings; the third direction can be parallel to the upper shell 11, refer to the front-back direction in the drawings.

The problem that the first matching part 1211a and the second matching part 1211b are difficult to assemble due to production errors is avoided, the first matching part 1211a and the second matching part 1211b can have sufficient matching strength, so that the first matching part 1211a and the second matching part 1211b are stably assembled along the second direction, the matching position of the first connecting seat 121a and the second connecting seat 121b can have sufficient strength and be easy to install, and the first connecting seat 121a can be independently installed and disassembled relative to the second connecting seat 121b.

[0078] As Figures 17 to 20 The upper shell 11 includes a flat portion 111 which can be provided with a flat surface and a connecting column 112 which is provided for positioning the terminal assembly 12 to the upper shell 11. As Figures 3 to 9 The first connecting seat 121a is provided with a matching hole 1211, the connecting column 112 passes through the matching hole 1211 and positions the first connecting seat 121a to the upper shell 11, wherein one end of the connecting column 112 can be fixedly connected with 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 the first connecting seat 121a is installed to the upper shell 11, the connecting column 112 can be aligned with the matching hole 1211, and the first connecting seat 121a is driven to move towards the upper shell 11; after the upper shell 11 is moved to the position, the first connecting seat 121a is locked and positioned to the upper shell 11 by connecting the connecting column 112 with a locking nut 13 or the like positioning member. The temperature sensor 122 is arranged in the first connecting seat 121a, as Figure 21 and Figure 22The temperature sensor 122 has a temperature sensing surface 1221 which can be matched with the flat portion 111 for the temperature sensor 122 to detect the temperature of the upper shell 11. The temperature sensing surface 1221 can be matched with the flat portion 111 in surface contact, that is, at least a part of the temperature sensing surface 1221 is attached to the flat portion 111. The sealing gasket 123 includes a first supporting portion 1231 which is arranged between the first connecting seat 121a and the upper shell 11 and surrounds the temperature sensor 122. The first supporting portion 1231 can prevent water and dust from entering the vicinity of the temperature sensing surface 1221, thus prolonging the service life of the temperature sensor 122 and improving the detection accuracy of the temperature sensor 122.

[0079] The flat portion 111 is arranged on the upper shell 11 and matched with the temperature sensing surface 1221 of the temperature sensor 122 in surface contact, thus optimizing the heat conduction effect between the temperature sensor 122 and the upper shell 11, improving the temperature detection accuracy of the temperature sensor 122 for the upper shell 11, and facilitating the control of the compressor 100. In addition, the sealing gasket 123 can prevent water and dust from entering the vicinity of the temperature sensor 122, thus further improving the temperature detection accuracy of the upper shell 11.

[0080] The compressor 100 is assembled according to the above method. Figure 1 After assembly, the surface of the upper shell 11 is rough, and the sealing gasket 123 deforms to seal, thus making the waterproof and dustproof level of the terminal assembly 12 reach IP54.

[0081] The upper shell 11 of the compressor 100 is usually an arc-shaped shell, and the outer side of the upper shell 11 can have an arc surface and a flat portion 111. The flat portion 111 can be arranged to protrude relative to the arc surface and form a flat structure. In addition, the first connecting seat 121a can be arranged on the flat portion 111 of the upper shell 11 and fixed to the upper shell 11 by a locking nut 13 or the like. In addition, the first connecting seat 121a can be provided with a mounting groove 1212, and at least a part of the temperature sensor 122 is arranged in the mounting groove 1212.

[0082] The first connecting seat 121a and the second connecting seat 121b are provided in a split structure in the application, and are locked by the connecting column 112. The pre-tightening force of the fixing member (i.e. the locking nut 13 described below) connected by the connecting column 112 on the first connecting seat 121a and the second connecting seat 121b is uneven, which causes the first connecting seat 121a and the second connecting seat 121b to be compressed and deformed under stress. The deformation of the first connecting seat 121a and the second connecting seat 121b can cause the sealing effect to be reduced. In order to ensure that the sealing effect is not affected after deformation, the application provides a compensation structure on the surface of the first connecting seat 121a and the second connecting seat 121b opposite the flat part 111. This includes but is not limited to the following embodiments and their combinations.

[0083] Embodiment 1

[0084] As Figure 27 , and in combination with Figure 2 and Figure 17 , the first connecting seat 121a has a first mating surface opposite the flat part 111. The first mating surface is inclined at a first predetermined angle x1 upward to the upper shell 11 relative to a set plane in a direction away from the matching hole 1211. The set plane is perpendicular to the axis of the matching hole 1211. By setting the first mating surface in an inclined form, when the first connecting seat 121a is positioned by the connecting column 112, the first support part 1231 can be deformed more uniformly, so that the first support part 1231 can be uniformly deformed, thereby improving the sealing effect on the space of the first connecting seat 121a and the upper shell 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 of the connecting column 112 is D3. The contact area of the locking nut 13 with the first connecting seat 121a is S3. The distance between the locking nut 13 and the flat part 111 is H, the elastic modulus of the first connecting seat 121a is E, and the maximum distance between the first connecting seat 121a and the axis of the matching hole 1211 is Y1. The first predetermined angle x1 satisfies: 0 < x1 ≤ 2 × arctan (T1 / (k × D3 × S3 × H × E × Y1), where k is a torque coefficient, which can be 0.2 ≤ k ≤ 0.3. Specifically, the locking pressure F = T1 / (k × D3) of the locking nut 13, the stress σ1 = F / S = T1 / (k × D3 × S3), and the strain ε = σ1 / E, where the maximum deformation x3 of the first connecting seat 121a = ε × H = (σ1 / E) × H = T1 / (k × D3 × S3 × E) (see Figure 27The graph shown in the middle circle G1 is the deformation amount of different positions of the first matching surface of the first connecting seat 121a when the first matching surface is perpendicular to the axis of the matching hole 1211, and it can be concluded that when the first predetermined angle x1 is set as x1=arctan(x3 / Y1)=arctan(T1 / (k×d×S3×H×E×Y1), the first connecting seat 121a has better sealing effect. According to actual detection and analysis, the first predetermined angle x1 and the uniformity of the deformation amount of the first supporting part 1231 gradually increase from 0 to arctan(T1 / (k×d×S3×H×E×Y1), and then gradually decrease, and when 0<x1≤2×arctan(T1 / (k×d×S3×H×E×Y1), the first supporting part can achieve better sealing effect. Therefore, the above setting of the present application can improve the uniformity of the deformation amount of the first supporting part and the sealing performance.

[0086] Alternatively, the first predetermined angle x1 can also be set as 0.05°≤x1≤2.5°. For example, x1 can be set as 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 amount of the sealing gasket and the sealing performance.

[0087] Embodiment 2

[0088] As Figure 28 , in combination with Figure 2 and Figure 17 The second connecting seat 121b has a second matching surface opposite to the flat part 111, and the second matching surface is inclined to the upper shell 11 by a second predetermined angle x2 in the direction away from the matching hole 1211 relative to the set plane, and the set plane is perpendicular to the axis of the matching hole 1211. By setting the second matching surface in the form of inclination, when the second connecting seat 121a is positioned by the connecting column 112, the second supporting part 1232 can be deformed more uniformly, so that the second supporting part 1232 can be uniformly deformed, and the sealing effect of the space of the second connecting seat 121a and the upper shell 11 is improved.

[0089] Optionally, the end of the connecting column 112 is connected with a locking nut 13, and the locking torque of the locking nut 13 is T1. The diameter 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 part 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. The second predetermined angle x2 satisfies: 0 < x2 ≤ 2 × arctan(T1 / (k × D3 × S3 × H × E × Y2), wherein k is a torque coefficient, and k can be 0.2 ≤ k ≤ 0.3. Specifically, the locking pressure of the locking nut 13 is F = T1 / (k × D3), the stress is σ1 = F / S3 = T1 / (k × D3 × S3), and the strain is ε = σ1 / E, wherein the maximum deformation x4 of the second connecting seat 121a is x4 = ε × H = (σ1 / E) × H = T1 / (k × D3 × S3 × E) (see Figure 28 The graph shown in the middle circle G2 is the deformation of different positions of the second matching surface of the second connecting seat 121b when the second matching surface is perpendicular to the axis of the matching hole 1211. The second predetermined angle can be set as x2 = arctan(x4 / Y2) = arctan(T1 / (k × D3 × S3 × H × E × Y2). The sealing performance can be improved.

[0090] Optionally, the second predetermined angle x2 can also be set as 0.05° ≤ x2 ≤ 2.5°. For example, x2 can be set as 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.

[0091] In addition, the second connecting seat 121b can have a hole corresponding to the matching hole 1211, and the connecting column 112 can pass through the hole and the matching hole to connect the locking nut 13.

[0092] Some application cases are provided in the present application, which is not a limitation on the protection scope of the present application.

[0093] Case 1: The locking torque of the locking nut 13 is 1.2 N.m. The diameter D3 of the connecting column 112 is 6 mm.

[0095] Case 3: the locking torque of the locking nut 13 is 1.2 N.m, the diameter D3 of the connecting column 112 is 6 mm, the first connecting seat 121a and the second connecting seat 121b are made of PP material with an elastic modulus E = 1.8 x 10 9 N / m 2 , wherein Y1 = 31 mm, Y2 = 44 mm, H = 32.2 mm, F = 1.2 / (0.25 x 0.006) = 800 N, the contact area S3 of the locking nut 13 and the first connecting seat 121a is 84.78 mm 2 , σ1 = F / A = 9.44 x 10 6 N / m 2 , strain ε = σ1 / E = 5.24 x 10 -3 , deformation x3 = x4 = ε x H = 0.17 mm, it can be obtained that x1 = arctan 0.12 / 31 = 0.31°; x2 = arctan 0.12 / 44 = 0.22°.

[0096] As Figure 5 and Figure 6 , in some embodiments, the connecting seat 121 is provided with a mounting groove 1212, and at least a part of the temperature sensor 122 is arranged in the mounting groove 1212.

[0097] In some embodiments, in combination Figure 3、 Figure 4 、 Figure 21 and Figure 22 The ratio of the center distance C1 of 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 of 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 attached to the flat portion 111, the contact area of the temperature sensor 122 and the upper shell 11 can be equal to the area S of the temperature sensing surface 1221, at this time the temperature sensing effect is best. Figure 24 is a curve graph of the contact area of the temperature sensor and the flat portion changing with C1 / D1, the vertical axis is the contact area of the temperature sensor and the upper shell, and the horizontal axis is the ratio C1 / D1, it can be seen that when C1 / D1=2.16, the contact area of 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, and when C1 / D1>2.16, with the increase of the ratio C1 / D1, the contact area of the temperature sensor 122 and the flat portion 111 of the upper shell 11 will continue to decrease, which affects the temperature detection of the temperature sensor 122; when C1 / D1≤1, the connecting column 112 of the temperature sensor 122 and the upper shell 11 may have size interference in the horizontal direction. In the present application, 1 < C1 / D1 ≤ 1.6, which can provide sufficient space for the first supporting portion 1231, improve the sealing performance of the first supporting portion 1231; in addition, it can also improve the contact area of the temperature sensor 122 and the flat portion 111, improve the temperature measurement accuracy and stability of the temperature sensor 122.

[0098] In addition, the upper shell 11 can also include an exhaust pipe 113, the upper shell 11 can be generally circular, the exhaust pipe 113 can be arranged along the axis of the upper shell 11, and the temperature sensor 122 and the first connecting seat 121a can be arranged on the side of the exhaust pipe 113.

[0099] In some embodiments, the ratio of the minimum distance C2 (not shown in the figure) between the central axis of the temperature sensor 122 and the edge of the flat portion 111 and the maximum outer diameter D1 of the temperature sensing surface 1221 satisfies: 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, etc. It can be guaranteed that the temperature sensing surface 1221 has the maximum contact area with the flat portion 111, effectively improving the detection accuracy of the temperature sensor 122, and in addition, the first supporting portion 1231 can cooperate with the flat portion 111 to improve the sealing effect, thereby further improving the detection accuracy of the temperature sensor 122.

[0100] As Figure 17 In some embodiments, the flat portion 111 includes a first side edge 1111, a second side edge 1112 and a third side edge 1113, the first side edge 1111 and the second side edge 1112 are arranged on both sides of the central axis of the upper shell 11, and the third side edge 1113 extends along the circumference of the upper shell 11, and the two ends of the third side edge 1113 are connected to the first side edge 1111 and the second side edge 1112. The flat portion 111 includes a flat surface enclosed by the first side edge 1111, the second side edge 1112 and the third side edge 1113, the connecting column 112 is arranged on the flat surface, and the temperature sensor 122 is attached to the flat surface. The flat surface enclosed by the first side edge 1111, the second side edge 1112 and the third side edge 1113 can stably cooperate with the temperature sensor 122 to improve the detection accuracy of the temperature sensor 122, and the connecting column 112 is arranged on the flat surface. It 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.

[0101] In addition, the inside of the compressor is a high-pressure environment, and the typical maximum pressure value is 4.2 MPa. The main function of the lower concave portion of the upper shell is to improve the pressure resistance. Through the above arrangement, it can avoid that the area of the flat portion 111 is too large, which leads to the decrease of the strength of the upper shell and does not meet the reliability requirements of the pressure resistance of the compressor.

[0102] Optionally, as Figure 17 The first side edge 1111 and the second side edge 1112 can be arranged as straight lines distributed on both sides of the central axis of the upper shell 11, and the third side edge 1113 is arranged as a circular arc edge with the central axis as the center. Among them, the distance between the intersection point of the first side edge 1111 and the second side edge 1112 and the central axis is C3, the radius size of the third side edge 1113 is R1, the radius size of the edge of the upper shell 11 is R2, the distance between the axis of the connecting column 112 and the central axis is C4, and the included angle between the first side edge 1111 and the second side edge 1112 is a.

[0103] Wherein, 0.7≤R1 / R2≤1 can be met, the third side 1113 is spaced apart from the edge of the upper shell 11, the flat portion 111 and the edge of the upper shell 11 can be provided with a smooth transition, the molding of the upper shell 11 is facilitated, and problems such as stress concentration at the edge of the upper shell 11 are avoided, and the structural stability and service life of the upper shell 11 are improved. In addition, 0.25≤C3 / R1≤0.6 can also be met; or, 0.32≤C4 / R1≤0.7; or, 60°≤a≤180°. The appropriate flat portion 111 can be provided on the upper shell 11, the connection seat 121 and the like are stably matched with the flat portion 111, so as to facilitate the stable installation of the connection seat 121 on the upper shell 11, improve the detection accuracy of the temperature sensor 122, and the like, and in addition, the material of the upper shell 11 can be reduced, and the cost is reduced.

[0104] 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 are circularly transitioned. The molding of the flat portion 111 is facilitated, the surface treatment of the flat portion 111 is facilitated to improve the surface flatness of the flat portion 111, so as to realize the stable matching of the temperature sensor 122 and the flat portion 111. The upper shell 11 can further include an exhaust pipe 113 extending along the axis of the upper shell 11. The exhaust of the compressor 100 is facilitated, and the performance of the compressor 100 is improved.

[0105] As Figure 5 In some embodiments, the first connection seat 121a is provided with a mounting groove 1212, at least a part of the temperature sensor 122 is arranged in the mounting groove 1212, the sealing gasket 123 further includes a protruding portion 1233, the protruding portion 1233 is arranged in the mounting groove 1212 and is arranged between the temperature sensor 122 and the first connection seat 121a along the axis of the temperature sensor 122. When the first connection seat 121a is installed on the upper shell 11, the temperature sensor 122 can be in contact with the flat portion 111. Since it is difficult to ensure that the flat portion 111 is completely flat in actual production and processing, the sealing gasket 123 is needed to ensure that the temperature sensor 122 is tightly attached to the upper shell 11. The protruding portion 1233 can elastically abut against the temperature sensor 122, and a force towards the flat portion 111 is applied to the temperature sensor 122, so as to realize the stable attachment of the temperature sensor 122 and the flat portion 111. In addition, the first supporting portion 1231 can realize the sealing of the mounting groove 1212, so that dust and other impurities can be prevented from entering the mounting groove 1212, and the protection effect of the temperature sensor 122 is optimized.

[0106] As Figure 5, the height dimension of the first supporting part 1231 is L1, the height dimension of the convex part 1233 is L2, the height dimension of the mounting groove 1212 is L3, and the height dimension of the temperature sensor 122 is L4, wherein L1+L3

[0107] In addition, the aforementioned height dimension of the first supporting part 1231 is L1, the height dimension of the convex part 1233 is L2, and the like refer to the height dimension before the terminal assembly 12 is installed, or the height dimension before the gasket 123 is compressed. In the compressor 100 that has been assembled, after the terminal assembly 12 is removed from the upper shell, the gasket 123 will partially recover under the action of elastic deformation. The height dimension of the first supporting part 1231 after the terminal assembly 12 is removed can be approximately equal to the aforementioned dimension L1, and the height dimension of the convex part 1233 can be approximately equal to the aforementioned dimension L2.

[0108] As shown in FIG. 6, the terminal assembly 12 is mounted on the upper shell 11, and the gasket 123 is compressed between the terminal assembly 12 and the upper shell 11. Figure 25 is a curve diagram of the detection temperature of the temperature sensor changing with the ratio (L1+L3) / (L2+L4), and T is the actual temperature value of the upper shell. As shown in the figure, when the ratio (L1+L3) / (L2+L4)≥1, the detection accuracy of the temperature sensor will be reduced. In addition, the ratio (L1+L3) / (L2+L4) is greater than 0.9, which can avoid damage caused by excessive compression of the gasket 123.

[0109] 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, the stop surface abutting against the protrusion 1233. The height dimension of the first support portion 1231 refers to the dimension of the first support portion 1231 along the 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 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, in other words, 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 of the temperature sensor 122 abutting against the protrusion 1233.

[0110] 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 disposed around the temperature sensor 122. 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 is disposed in the first positioning groove 1213. The first positioning rib 1234 and the first positioning groove 1213 can be used to stably connect the first support 1231 and 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. Furthermore, the sealing gasket 123 can be positioned on the first connecting seat 121a before it is installed on the upper housing 11, and then the first connecting seat 121a with the sealing gasket 123 installed can be installed on the upper housing 11.
