Embodiments of the present invention

[0041] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0042] This application discloses a temperature sensor assembly 100 for a compressor 1000, which allows the temperature sensing element 20 to make close contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensing element 20 on the compressor body 200. This application also discloses a compressor 1000 and heating and ventilation equipment.

[0043] As shown in Figures 1 to 9, the temperature sensor assembly 100 for a compressor 1000 according to an embodiment of this application includes a housing 10, a temperature sensing element 20, and an elastic element 30.

[0044] The housing 10 has a mating surface 11 and a receiving groove 12. The opening 13 of the receiving groove 12 is located on the mating surface 11. At least a portion of the temperature sensing element 20 is located in the receiving groove 12. The temperature sensing element 20 has a temperature sensing end 23, which is opposite to the opening 13. The elastic element 30 includes a first elastic portion 31 located on the inner bottom surface of the receiving groove 12 and opposite to the opening 13. The first elastic portion 31 is used to elastically press the temperature sensing element 20 toward the opening 13. This arrangement can improve the temperature sensing effect of the temperature sensor assembly 100.

[0045] When the temperature sensor assembly 100 is installed on the compressor body 200, the mating surface 11 of the cover 10 can be connected to the compressor body 200, and the opening 13 of the cover 10 can face the compressor 1000. The temperature sensing element 20 is disposed in the receiving groove 12 and positioned on the compressor body 200 by the cover 10. The receiving groove 12 is provided with a first elastic part 31 of the elastic element 30. The first elastic part 31 is opposite to the opening 13 and elastically presses against the temperature sensing element 20 towards the opening 13 of the cover 10, so that the temperature sensing end 23 of the temperature sensing element 20 is in close contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensing element 20 on the compressor body 200. In this way, by sensing the temperature of the compressor body 200 through the temperature sensing element 20, it is convenient to take protective action when the temperature of the compressor body 200 exceeds the predetermined range, so as to avoid damage to the compressor body 200.

[0046] Therefore, in the compressor 100 temperature sensor assembly 100 according to the embodiment of this application, the first elastic part 31 of the elastic member 30 presses against the temperature sensor 20 toward the opening 13 of the cover 10, so that the temperature sensor 20 is in close contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensor 20 on the compressor body 200.

[0047] As shown in Figure 4, in some embodiments of this application, the elastic member 30 further includes a second elastic portion 32, which is disposed on the outside of the mating surface 11. It can be understood that the mating surface 11 of the cover 10 has opposite inner and outer sides, with the inner side of the mating surface 11 facing the receiving groove 12 of the cover 10 and the outer side of the mating surface 11 facing away from the receiving groove 12 of the cover 10. The second elastic portion 32 of the elastic member 30 can be disposed on the outside of the mating surface 11. When the temperature sensor assembly 100 is installed on the compressor body 200, the second elastic portion 32 of the elastic member 30 can be squeezed by the cover 10 and the compressor 1000, thereby sealing the gap between the cover 10 and the compressor body 200, thereby improving the sealing performance of the temperature sensor assembly 100 and preventing the external environment from affecting the normal operation of the temperature sensor 20.

[0048] As shown in Figures 1 to 6, in some embodiments of this application, the temperature sensing element 20 includes a body portion 21 disposed in the receiving groove 12. In the free state, the maximum dimension of the body portion 21 along the axis of the opening 13 is H1, the maximum depth dimension of the receiving groove 12 along the axis of the opening 13 is H2, the minimum depth dimension of the second elastic portion 32 along the axis of the opening 13 is H3, and the maximum thickness dimension of the first elastic portion 31 along the axis of the opening 13 is H4, wherein H2+H3

[0049] It is understood that the temperature sensor assembly 100 has an installed state and a free state. In the installed state, the temperature sensor assembly 100 is installed on the compressor body 200, and in the free state, the temperature sensor assembly 100 is not installed on the compressor body 200. Specifically, in the installed state, the first elastic part 31 and the second elastic part 32 undergo elastic deformation, and the thickness dimensions of the first elastic part 31 and the second elastic part 32 change, such that the sum of the maximum depth dimension of the receiving groove 12 along the axis of the opening 13 and the minimum depth dimension of the second elastic part 32 along the axis of the opening 13 is equal to the sum of the maximum dimension of the body part 21 along the axis of the opening 13 and the maximum thickness dimension of the first elastic part 31 along the axis of the opening 13. As shown in Figure 6, in this state, the maximum dimension of the body part 21 along the axis of the opening 13 is H1, the maximum depth dimension of the receiving groove 12 along the axis of the opening 13 is H2, the minimum depth dimension of the second elastic part 32 along the axis of the opening 13 is H3', and the maximum thickness dimension of the first elastic part 31 along the axis of the opening 13 is H4'.

[0050] To meet the dimensional requirements in the installation state, in the free state, as shown in Figure 5, the maximum dimension of the body 21 along the axis of the opening 13 is H1, the maximum depth dimension of the receiving groove 12 along the axis of the opening 13 is H2, the minimum depth dimension of the second elastic part 32 along the axis of the opening 13 is H3, and the maximum thickness dimension of the first elastic part 31 along the axis of the opening 13 is H4, satisfying the relationship H2+H3

[0051] ​​In the free state, the maximum dimension of the main body part 21 along the axis of the opening 13 is H1, the maximum depth dimension of the receiving groove 12 along the axis of the opening 13 is H2, the minimum depth dimension of the second elastic part 32 along the axis of the opening 13 is H3, and the maximum thickness dimension of the first elastic part 31 along the axis of the opening 13 is H4, satisfying the relationship of H1 < H2 + H3. In this way, the temperature sensing element 20 can be avoided from being fractured during installation.

[0052] As can be seen from FIG. 10, the minimum depth dimension H3 of the second elastic part 32 along the axis of the opening 13 and the maximum thickness dimension H4 of the first elastic part 31 along the axis of the opening 13 are optimal within the range of H1 and H1 + H4. When H1 ≥ H2 + H3, the force on the temperature sensing element 20 is relatively large and it is easy to fracture the temperature sensing element 20; when H2 + H3 ≥ H1 + H4, the force on the temperature sensing element is relatively small and it cannot be in good close contact with the compressor main body 200, resulting in temperature sensing failure. As can be seen from FIG. 11, this embodiment satisfies the relationship of H1 < H2 + H3 < H1 + H4, making the failure rate of the temperature sensing element 20 and the compressor 1000 significantly lower compared with the prior art.

[0053] As shown in FIGS. 4 to 7, in some embodiments of the present application, the elastic member 30 further includes a peripheral wall part 33. The peripheral wall part 33 connects the first elastic part 31 and the second elastic part 32. The peripheral wall part 33 is provided between the inner peripheral surface of the receiving groove 12 and the temperature sensing element 20, which can play a protective role for the temperature sensor and avoid hard contact between the cover shell 10 and the temperature sensing element 20, resulting in structural damage.

[0054] Specifically, the receiving groove 12 has an inner bottom surface opposite to the opening 13 and an inner peripheral surface connecting the inner bottom surface. The elastic member 30 can be arranged in the receiving groove 12. The first elastic part 31 of the elastic member 30 is arranged on the inner bottom surface of the receiving groove 12, the peripheral wall part 33 of the elastic member 30 is arranged on the inner peripheral surface of the receiving groove 12, and the temperature sensing element 20 is arranged in the elastic member 30, that is, the temperature sensing element 20 is wrapped by the first elastic part 31 and the peripheral wall part 33 to avoid hard contact and damage between the temperature sensing element 20 and the cover shell 10. And the first elastic part 31, the peripheral wall part 33 and the second elastic part 32 are connected along the axis direction of the opening 13. During installation, the first elastic part 31 elastically presses the temperature sensing element 20 towards the opening 13, making the temperature sensing element 20 in good close contact with the compressor main body 200, thereby improving the temperature sensing effect of the temperature sensing element 20; in addition, the second elastic part 32 is pressed by the mating surface 11 and the compressor main body 200, and seals the gap between the mating surface 11 of the cover shell 10 and the compressor main body 200, so as to improve the sealing performance of the compressor 1000 assembly.

[0055] As shown in Figure 2, in some embodiments of this application, the temperature sensing element 20 includes a body portion 21 and a first terminal 22. The body portion 21 is disposed in the receiving groove 12. The peripheral wall portion 33 includes at least two portions distributed circumferentially along the elastic member 30, and an avoidance structure 333 is formed between adjacent peripheral wall portions 33. The first terminal 22 passes through the avoidance structure 333 and is inserted into the cover 10; and / or, a connector 40 is provided inside the cover 10, and the first terminal 22 passes through the cover 10 and is electrically connected to the connector 40. This arrangement facilitates the connection between the temperature sensing element 20 and the connector 40, enabling the power supply and signal transmission of the temperature sensing element 20.

[0056] Specifically, a connector 40 is provided inside the housing 10. The connector 40 can be connected to external power supplies and / or controllers and other functional devices via a wiring harness. The peripheral wall portion 33 of the elastic member 30 is located between the body portion 21 of the temperature sensing member 20 and the inner peripheral surface of the receiving groove 12 to avoid hard contact between the body portion 21 of the temperature sensing member 20 and the inner peripheral surface of the receiving groove 12. The body portion 21 of the temperature sensing member 20 is connected to a first terminal 22, which is connected to the connector 40, so that the temperature sensing member 20 can be connected to external power supplies and / or controllers and other functional devices. The temperature sensor 20 can detect the temperature signal of the compressor body 200 and transmit it to the controller. It can also supply external power to the temperature sensor 20 through the connector 40. In order for the temperature sensor 20 to connect with the external power supply and / or controller, the peripheral wall portion 33 can include at least two distributed along the circumference of the elastic member 30, and a clearance structure 333 is formed between two adjacent peripheral wall portions 33. In this way, the first terminal 22 connected to the body portion 21 can pass through the clearance structure 333 and be inserted into the cover 10 to connect with the connector 40 inside the cover 10.

[0057] As shown in Figure 4, in some embodiments of this application, the peripheral wall portion 33 includes a first wall portion 331 and a second wall portion 332. The first wall portion 331 and the second wall portion 332 are distributed along the axial direction of the opening 13. The first wall portion 331 is connected to the first elastic portion 31, and the second wall portion 332 is connected to the second elastic portion 32. The second wall portion 332 protrudes from the first wall portion 331 in a direction away from the temperature sensing element 20, and a stepped structure is constructed between the first wall portion 331 and the second wall portion 332. In this way, the elastic element 30 can be stably disposed in the receiving groove 12, thereby improving the contact stability between the temperature sensing element 20 and the compressor body 200.

[0058] Specifically, in the direction from the inner bottom surface of the receiving groove 12 to the opening 13, the first elastic part 31, the first wall part 331, the second wall part 332, and the second elastic part 32 are connected in sequence. The first elastic part 31, the first wall part 331, and the second wall part 332 are provided on the outer surface of the temperature sensing element 20. The second elastic part 32 is arranged around the temperature sensing element 20 and displays the temperature sensing end 23 of the temperature sensing element 20, so that the temperature sensing end 23 can sense the temperature of the compressor body 200. More specifically, the second wall part 332 protrudes from the first wall part 331 in the direction away from the temperature sensing element 20, and a stepped structure is constructed between the first wall part 331 and the second wall part 332. In this way, the roughness of the elastic element 30 can be increased, so that the elastic element 30 is stably set in the receiving groove 12, and the elastic element 30 is prevented from moving relative to the receiving groove 12, which would cause the elastic element 30 to fail to elastically press the temperature sensing element 20 well, resulting in the temperature sensing element 20 failing to sense temperature.

[0059] As shown in Figure 2, in some embodiments of this application, the temperature sensing element 20 is provided with a first part 211 and a second part 212. The first part 211 and the second part 212 are distributed along the axial direction of the opening 13. The outer peripheral surface of the second part 212 protrudes from the outer peripheral surface of the first part 211. The first part 211 and the first wall portion 331 are opposite to each other in the radial direction of the temperature sensing element 20, and the second part 212 and the second wall portion 332 are opposite to each other in the radial direction of the temperature sensing element 20. In this way, the temperature sensing element 20 can be stably disposed in the elastic member 30, thereby improving the contact stability between the temperature sensing element 20 and the compressor body 200.

[0060] Specifically, in conjunction with the foregoing, the temperature sensing element 20 includes a body portion 21 and a first terminal block 22. The body portion 21 includes a first portion 211 and a second portion 212. An elastic element 30 is disposed on the outer surface of the body portion 21. The first wall portion 331 of the elastic element 30 is radially opposite to the first portion 211 of the body portion 21, and the second wall portion 332 of the elastic element 30 is radially opposite to the second portion 212 of the body portion 21. The outer peripheral surface of the second portion 212 of the body portion 21 protrudes from the first portion 211. On the outer peripheral surface, in the installed state, the second part 212 of the main body 21 presses against the second wall part 332 of the elastic member 30 in the radial direction of the temperature sensing member 20 and in the direction away from the temperature sensing member 20, so that the elastic member 30 and the temperature sensing member 20 fit more tightly, and the stepped structure of the elastic member 30 can press more stably against the inner wall surface of the receiving groove 12, thereby improving the assembly stability of the elastic member 30 and the cover 10, so that the elastic member 30 can press against the temperature sensing member 20 more stably, thereby improving the contact stability between the temperature sensing member 20 and the compressor body 200.

[0061] As shown in Figure 3, in some embodiments of this application, the inner circumferential surface of the receiving groove 12 is provided with a first surface 121 and a second surface 122. The first surface 121 and the second surface 122 are distributed along the axial direction of the opening 13. The first surface 121 protrudes into the receiving groove 12, and the first surface 121 and the first wall portion 331 are radially opposite to each other in the receiving groove 12. The second surface 122 and the second wall portion 332 are radially opposite to each other in the receiving groove 12. In this way, the elastic member 30 can be stably disposed in the receiving groove 12, thereby improving the contact stability between the temperature sensing member 20 and the compressor body 200.

[0062] Specifically, the first wall portion 331 of the elastic member 30 corresponds to the first surface 121, and the second wall portion 332 of the elastic member 30 corresponds to the second surface 122. In the installed state, the first wall portion 331 of the elastic member 30 elastically presses against the first portion 211 of the temperature sensing member 20 and the first surface 121 of the receiving groove 12, and the second wall portion 332 of the elastic member 30 elastically presses against the second portion 212 of the temperature sensing member 20 and the second surface 122 of the receiving groove 12, so that the elastic member 30 and the temperature sensing member 20 can be stably assembled on the cover 10, and the stepped structure of the elastic member 30 can be limited between the first surface 121 and the second surface 122 of the receiving groove 12 to improve the assembly strength, so that the first elastic portion 31 of the elastic member 30 can effectively elastically press against the temperature sensing member 20, thereby improving the contact stability between the temperature sensing member 20 and the compressor body 200.

[0063] As shown in Figures 1 and 8, in some embodiments of this application, a connector 40 is provided inside the housing 10, and the temperature sensor assembly 100 also includes a wire harness, which is electrically connected to the connector 40. The connector 40, the wire harness, and the housing 10 are injection molded in a secondary manner. This can improve the sealing performance of the temperature sensor assembly 100, thereby improving the working stability of the temperature sensor assembly 100.

[0064] Specifically, the housing 10 can be injection molded in one step. The connector 40 is disposed inside the housing 10 and electrically connected to the temperature sensing element 20 in the receiving groove 12. As mentioned above, the body 21 of the temperature sensing element 20 is disposed in the receiving groove 12, and the elastic element 30 is disposed on the outer surface of the body 21. The elastic element 30 is provided with a clearance structure 333, which facilitates the first terminal 22 to pass through the clearance structure 333 to electrically connect to the body 21 of the elastic element 30 and the connector 40 respectively. The connector 40 can also be electrically connected to the wire harness to connect to external power supplies and / or controllers and other functional devices. Subsequently, the connector 40, the wire harness and the housing 10 can be injection molded in two steps. This can improve the assembly stability of the connector 40, the wire harness and the housing 10, and improve the sealing performance of the temperature sensor assembly 100, preventing external environmental contamination of the internal components of the temperature sensor assembly 100, thereby improving the working stability of the temperature sensor assembly 100.

[0065] In some embodiments of this application, the elastic element 30 is integrally formed with the inner wall of the receiving groove 12 by a melting process. This can improve the connection stability between the elastic element 30 and the cover 10, and prevent the elastic element 30 from moving relative to the cover 10, which would prevent the elastic element 30 from effectively pressing against the temperature sensing element 20, resulting in poor contact between the temperature sensing element 20 and the compressor body 200.

[0066] As shown in Figure 8, in some embodiments of this application, the housing 10 has mounting holes 50, which are connected to the compressor body 200 by fasteners. Specifically, the housing 10 may have mounting holes 50, and the compressor body 200 may have connecting holes corresponding to the mounting holes 50. Fasteners may be inserted through the mounting holes 50 and the connecting holes respectively to install the housing 10 on the compressor body 200, thereby realizing the assembly of the temperature sensor assembly 100 on the compressor body 200. Of course, there may be multiple mounting holes 50 and multiple connecting holes. Multiple mounting holes 50 correspond to multiple connecting holes and are connected by fasteners to improve the connection strength between the temperature sensor assembly 100 and the compressor body 200.

[0067] Furthermore, in some specific examples of this application, after the connector 40, wire harness and housing 10 are connected, a plastic shell can be formed on the outside of the housing 10 by secondary injection molding. The plastic shell can fix the connector 40, wire harness and housing 10. The plastic shell can be provided with mounting holes 50 and connected to the compressor body 200 by fasteners. In this way, the processing complexity of the housing 10 can be reduced and the assembly efficiency can be improved.

[0068] As shown in Figures 1 to 11, the compressor 1000 according to the embodiments of this application includes a compressor body 200 and a temperature sensor assembly 100 as described in the above embodiments.

[0069] The temperature sensor assembly 100 is located on the compressor body 200. By applying the aforementioned temperature sensor assembly 100, the compressor body 200 is temperature-sensing, thereby taking protective actions based on the working state of the compressor body 200 to prevent damage to the compressor 1000.

[0070] Specifically, the body portion 21 of the elastic element 30 and the temperature sensing element 20 is disposed within the receiving groove 12 of the cover 10. The mating surface 11 of the cover 10 is connected to the compressor body 200, and the cover 10 is mounted on the compressor body 200 through the mounting hole 50. The opening 13 of the cover 10 is opposite to the compressor body 200. The first elastic portion 31 of the elastic element 30 elastically presses against the temperature sensing element 20 towards the opening 13, so that the temperature sensing end 23 of the temperature sensing element 20 can be in close contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensing element 20 on the compressor body 200. Furthermore, a second elastic portion 32 of the elastic element 30 is provided on the outer side of the mating surface 11. In the installed state, the second elastic portion 32 undergoes elastic deformation under the pressure of the mating surface 11 and the compressor body 200 to seal the gap between the mating surface 11 and the compressor body 200, thereby improving the sealing performance of the compressor 1000.

[0071] Furthermore, in the free state, the temperature sensor assembly 100 has the following dimensions: the maximum dimension of the main body 21 along the axis of the opening 13 is H1; the maximum depth dimension of the receiving groove 12 along the axis of the opening 13 is H2; the minimum thickness dimension of the second elastic part 32 along the axis of the opening 13 is H3; and the maximum thickness dimension of the first elastic part 31 along the axis of the opening 13 is H4. These dimensions satisfy the relationship H2 + H3 < H1 + H4. Thus, in the installed state, the first elastic part 31 of the elastic member 30 can elastically press against the temperature sensor 20 towards the opening 13, ensuring close contact between the temperature sensing end 23 of the temperature sensor 20 and the compressor body 200, thereby improving the temperature sensing effect of the temperature sensor 20. Additionally, the relationship H1 < H2 + H3 is also satisfied to prevent the temperature sensor 20 from being crushed in the installed state.

[0072] Furthermore, the elastic member 30 includes a peripheral wall portion 33, which is disposed between the inner peripheral surface of the receiving groove 12 and the temperature sensing member 20, thus protecting the temperature sensing member 20 and preventing damage caused by contact between the temperature sensing member 20 and the inner peripheral surface of the receiving groove 12. The peripheral wall portion 33 includes at least two circumferentially distributed portions, with a clearance structure 333 formed between adjacent portions 33 to allow the first terminal 22 to pass through the clearance structure 333 for electrical connection with the connector 40 inside the housing 10. The connector 40 can be connected to a wiring harness, which in turn connects to an external power supply and / or controller, etc., to transmit the temperature sensing signal from the temperature sensing member 20 and to supply power to the temperature sensing member 20.

[0073] Furthermore, the peripheral wall portion 33 includes a first wall portion 331 and a second wall portion 332, with the second wall portion 332 protruding from the first wall portion 331 in a direction away from the temperature sensing element 20; the temperature sensing element 20 is provided with a first portion 211 and a second portion 212, with the outer peripheral surface of the second portion 212 protruding from the outer peripheral surface of the first portion 211; the inner peripheral surface of the receiving groove 12 is provided with a first surface 121 and a second surface 122, with the first surface 121 protruding into the receiving groove 12 and the second surface 122 protruding from it. Thus, in the temperature sensor assembly 10... In the 0, the first part 211 of the temperature sensing element 20 and the first surface 121 of the receiving groove 12 can elastically press against the first wall 331 of the elastic element 30, and the second part 212 of the temperature sensing element 20 and the second surface 122 of the receiving groove 12 can elastically press against the second wall 332 of the elastic element 30, so that the temperature sensing element 20 and the elastic element 30 can be more stably disposed in the housing 10, thereby making the temperature sensing element 20 more stably contact the compressor body 200 and improving the temperature sensing effect of the temperature sensor assembly 100.

[0074] As shown in Figure 9, in some embodiments of this application, the compressor 1000 further includes a terminal assembly 300. The terminal assembly 300 includes a base, a second terminal block, and a second wiring harness. The base block is disposed on the outer surface of the compressor body 200 and is integrally formed with the cover 10. The second terminal block is disposed inside the base block and is used for electrical connection with the compressor body 200. The second wiring harness is connected to the second terminal block and is used for connecting to the power supply. In this way, the terminal assembly 300 can be integrated with the temperature sensor assembly 100 to improve assembly efficiency.

[0075] Specifically, the base of the terminal assembly 300 is integrally formed with the housing 10. For example, the housing 10, the wire harness, and the connector 40 are injection molded in a secondary manner, so that the base of the terminal assembly 300 is formed on the outside of the housing 10. The base is provided with a second terminal and a second wire harness. The second terminal can be electrically connected to the metal post extending from the compressor body 200. The second terminal is connected to the wire harness, and the wire harness can be connected to an external power source to supply power to the compressor body 200. The base of the terminal assembly 300 is integrally formed with the housing 10 of the temperature sensor assembly 100, which can improve the assembly efficiency of the compressor 1000.

[0076] In some embodiments of this application, the terminal assembly 300 further includes a seal disposed between the outer surface of the housing and the compressor body 200 to seal the gap between the housing and the compressor body 200. This improves the sealing performance of the terminal assembly 300 and prevents external environmental contamination of the interior of the terminal assembly 300, which could cause the functional devices to malfunction. Furthermore, the seal and the elastic member 30 are integrally formed. Thus, during assembly, the second elastic portion 32 of the seal and the elastic member 30 can respectively seal the gaps between the housing 10 and the compressor body 200, improving assembly efficiency and sealing performance.
