DETAILED DESCRIPTION

[0039] The following describes in detail embodiments of the present invention, 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 explain the present invention, and should not be construed as limiting the present invention.

[0040] The present invention provides a temperature sensor assembly 100 for a compressor 1000, which can make the temperature sensing element 20 closely contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensing element 20 on the compressor body 200. The present invention also provides a compressor 1000 and a heating and ventilation device.

[0041] like Figures 1 to 9 As shown, a temperature sensor assembly 100 for a compressor 1000 according to an embodiment of the present invention includes a housing 10 , a temperature sensing member 20 and an elastic member 30 .

[0042] Among them, the cover 10 has a mating surface 11 and a receiving groove 12, the opening 13 of the receiving groove 12 is provided on the mating surface 11, at least a part of the temperature sensing component 20 is provided in the receiving groove 12, the temperature sensing component 20 has a temperature sensing end 23, and the temperature sensing end 23 is opposite to the opening 13. The elastic component 30 includes a first elastic portion 31 provided on the inner bottom surface of the receiving groove 12 and opposite to the opening 13, and the first elastic portion 31 is used to elastically press the temperature sensing component 20 toward the opening 13; such an arrangement can improve the temperature sensing effect of the temperature sensor assembly 100.

[0043] When the temperature sensor assembly 100 is installed on the compressor body 200, the mating surface 11 of the cover 10 can be matched and connected with the compressor body 200, and the opening 13 of the cover 10 can face the compressor 1000. The temperature sensing element 20 is arranged in the accommodating groove 12 and is positioned on the compressor body 200 through the cover 10, wherein a first elastic part 31 of the elastic element 30 is provided in the accommodating groove 12, and the first elastic part 31 is opposite to the opening 13 and elastically presses the temperature sensing element 20 toward 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, through the temperature sensing element 20 sensing the temperature of the compressor body 200, it is convenient to take protective action when the temperature of the compressor body 200 exceeds a predetermined range to avoid damage to the compressor body 200.

[0044] Therefore, according to the embodiment of the present invention, the compressor 1000 uses the temperature sensor assembly 100, which presses the temperature sensing member 20 toward the opening 13 of the cover 10 through the first elastic part 31 of the elastic member 30, so that the temperature sensing member 20 is in close contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensing member 20 on the compressor body 200.

[0045] like Figure 4 As shown, in some embodiments of the present invention, the elastic member 30 also includes a second elastic portion 32, and the second elastic portion 32 is arranged on the outside of the mating surface 11; it can be understood that the mating surface 11 of the cover 10 has relative inner and outer sides, the inner side of the mating surface 11 faces the accommodating groove 12 of the cover 10, and the outer side of the mating surface 11 faces away from the accommodating groove 12 of the cover 10. The second elastic portion 32 of the elastic member 30 can be arranged on the outside of the mating surface 11, and 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.

[0046] like Figures 1 to 6As shown, in some embodiments of the present invention, the temperature sensing element 20 includes a main body 21, which is arranged in the accommodating groove 12. When the temperature sensor assembly 100 is in a free state, the maximum dimension of the main body 21 along the axis of the opening 13 is H1, the maximum depth dimension of the accommodating 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

[0047] It can be 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 portion 31 and the second elastic portion 32 are elastically deformed, and the thickness dimension of the first elastic portion 31 and the thickness dimension of the second elastic portion 32 change, so that the sum of the maximum depth dimension of the accommodating groove 12 along the axis of the opening 13 and the minimum depth dimension of the second elastic portion 32 along the axis of the opening 13 is equal to the sum of the maximum dimension of the main body portion 21 along the axis of the opening 13 and the maximum thickness dimension of the first elastic portion 31 along the axis of the opening 13; as shown in FIG. Figure 6 In this state, the maximum dimension of the main body 21 along the axis of the opening 13 is H1, the maximum depth dimension of the accommodating 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'.

[0048] In order to meet the dimensional relationship in the installed state, the temperature sensor assembly 100 is in a free state, such as Figure 5 The maximum dimension of the main body 21 along the axis of the opening 13 is H1, the maximum depth dimension of the accommodating 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, satisfying the relationship H2+H3

[0049] ​​In the free state, the maximum dimension of the main body 21 along the axis of the opening 13 is H1, the maximum depth dimension of the accommodating 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, satisfying the relationship H1<H2+H3. In this way, the temperature sensing component 20 can be prevented from being crushed during installation.

[0050] Combine Figure 10 It can be seen that 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. The best range is between H1 and H1+H4. When H1≥H2+H3, the force on the temperature sensing element 20 is large and it is easy to crush the temperature sensing element 20; when H2+H3≥H1+H4, the force on the temperature sensing element is small and it cannot be in close contact with the compressor body 200, resulting in failure of temperature sensing. Figure 11 It can be seen that this embodiment satisfies the relationship: H1<H2+H3

[0051] like Figures 4 to 7 As shown, in some embodiments of the present invention, the elastic member 30 further includes a peripheral wall portion 33, which connects the first elastic portion 31 and the second elastic portion 32. The peripheral wall portion 33 is arranged between the inner peripheral surface of the accommodating groove 12 and the temperature sensing member 20, and can protect the temperature sensor to avoid hard contact between the cover 10 and the temperature sensing member 20, which may cause structural damage.

[0052] Specifically, the accommodating groove 12 has an inner bottom surface opposite to the opening 13 and an inner peripheral surface connected to the inner bottom surface. The elastic member 30 can be arranged in the accommodating groove 12, the first elastic portion 31 of the elastic member 30 is arranged on the inner bottom surface of the accommodating groove 12, and the peripheral wall portion 33 of the elastic member 30 is arranged on the inner peripheral surface of the accommodating groove 12, and the temperature sensing member 20 is arranged in the elastic member 30, that is, the temperature sensing member 20 is wrapped by the first elastic portion 31 and the peripheral wall portion 33 to avoid damage caused by hard contact between the temperature sensing member 20 and the cover shell 10. The first elastic portion 31, the peripheral wall portion 33 and the second elastic portion 32 are connected along the axial direction of the opening 13. During installation, the first elastic portion 31 elastically presses the temperature sensing component 20 toward the opening 13, so that the temperature sensing component 20 is in close contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensing component 20; in addition, the second elastic portion 32 is pressed by the mating surface 11 and the compressor body 200, and seals the gap between the mating surface 11 of the cover 10 and the compressor body 200 to improve the sealing performance of the compressor 1000 assembly.

[0053] like Figure 2 ​As shown, in some embodiments of the present invention, the temperature sensing element 20 includes a main body 21 and a first terminal 22, the main body 21 is arranged in the accommodating groove 12, the peripheral wall portion 33 includes at least two distributed along the circumference of the elastic element 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 shell 10; and / or, a connector 40 is provided in the cover shell 10, the first terminal 22 passes through the cover shell 10, and is electrically connected to the connector 40; such a configuration can facilitate the connection between the temperature sensing element 20 and the connector 40, thereby realizing power supply and signal transmission of the temperature sensing element 20.

[0054] Specifically, a connector 40 is provided in the housing 10, and the connector 40 can be connected to an external power supply and / or controller and other functional devices through a wiring harness. The peripheral wall portion 33 of the elastic member 30 is located between the main body 21 of the temperature sensing member 20 and the inner peripheral surface of the accommodating groove 12 to avoid hard contact between the main body 21 of the temperature sensing member 20 and the inner peripheral surface of the accommodating groove 12. The main body 21 of the temperature sensing member 20 is connected to a first terminal 22, and the first terminal 22 is connected to the connector 40, so that the temperature sensing member 20 can be connected to an external power supply and / or controller and other functional devices. The temperature signal of the compressor body 200 detected by the temperature sensing element 20 can be transmitted to the controller, and the external power supply can also be supplied to the temperature sensing element 20 through the connector 40; and in order to connect the temperature sensing element 20 to an external power supply and / or controller, etc.; the peripheral wall portion 33 can include at least two distributed along the circumference of the elastic element 30, and an avoidance structure 333 can be formed between the two adjacent peripheral wall portions 33, so that the first terminal 22 connected to the main body 21 can be passed through the avoidance structure 333 and inserted into the cover 10 to be connected to the connector 40 in the cover 10.

[0055] like Figure 4 As shown, in some embodiments of the present invention, the peripheral wall portion 33 includes a first wall portion 331 and a second wall portion 332, and 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 first wall portion 331 and the second wall portion 332 are connected, and the second wall portion 332 protrudes from the first wall portion 331 in a direction away from the temperature sensing member 20, and a step structure is constructed between the first wall portion 331 and the second wall portion 332; in this way, the elastic member 30 can be stably arranged in the accommodating groove 12, thereby improving the contact stability between the temperature sensing member 20 and the compressor body 200.

[0056] When the cam 330 is in the closed position, the spring 331 is in the closed position, and the spring 332 is in the open position, so that the cam 330 can be turned off.

[0057] like Figure 2 As shown, in some embodiments of the present invention, the temperature sensing element 20 is provided with a first portion 211 and a second portion 212, and the first portion 211 and the second portion 212 are distributed along the axial direction of the opening 13, and the outer peripheral surface of the second portion 212 protrudes from the outer peripheral surface of the first portion 211, and the first portion 211 is opposite to the first wall portion 331 in the radial direction of the temperature sensing element 20, and the second portion 212 is opposite to the second wall portion 332 in the radial direction of the temperature sensing element 20; in this way, the temperature sensing element 20 can be stably arranged in the elastic element 30, thereby improving the contact stability between the temperature sensing element 20 and the compressor body 200.

[0058] Specifically, in combination with the above, the temperature sensing member 20 includes a main body 21 and a first terminal 22, the main body 21 includes a first portion 211 and a second portion 212, and the elastic member 30 is provided on the outer surface of the main body 21, wherein the first wall portion 331 of the elastic member 30 is opposite to the first portion 211 of the main body 21 along the radial direction of the temperature sensing member 20, and the second wall portion 332 of the elastic member 30 is opposite to the second portion 212 of the main body 21 along the radial direction of the temperature sensing member 20; the outer peripheral surface of the second portion 212 of the main body 21 protrudes from the first portion 211 The outer peripheral surface, so that, in the installed state, the second part 212 of the main body 21 presses the second wall portion 332 of the elastic member 30 along the radial direction of the temperature sensing member 20 and away from the temperature sensing member 20, so that the elastic member 30 and the temperature sensing member 20 are more closely matched, and the step structure of the elastic member 30 can be more stably pressed against the inner wall surface of the accommodating groove 12, so as to improve the assembly stability of the elastic member 30 and the cover 10, so that the elastic member 30 can be more stably pressed against the temperature sensing member 20, so as to improve the contact stability between the temperature sensing member 20 and the compressor body 200.

[0059] like Figure 3As shown, in some embodiments of the present invention, the inner circumferential surface of the accommodating groove 12 is provided with a first surface 121 and a second surface 122, and the first surface 121 and the second surface 122 are distributed along the axial direction of the opening 13, the first surface 121 protrudes the second surface 122 toward the accommodating groove 12, the first surface 121 and the first wall portion 331 are opposite to each other along the radial direction of the accommodating groove 12, and the second surface 122 and the second wall portion 332 are opposite to each other along the radial direction of the accommodating groove 12; in this way, the elastic member 30 can be stably arranged in the accommodating groove 12, thereby improving the contact stability between the temperature sensing member 20 and the compressor body 200.

[0060] 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 between the first part 211 of the temperature sensing member 20 and the first surface 121 of the accommodating groove 12, and the second wall portion 332 of the elastic member 30 elastically presses between the second part 212 of the temperature sensing member 20 and the second surface 122 of the accommodating groove 12, so that the elastic member 30 and the temperature sensing member 20 can be stably assembled on the cover 10, and the step structure of the elastic member 30 can be limited between the first surface 121 and the second surface 122 of the accommodating groove 12 to improve the assembly strength, so that the first elastic portion 31 of the elastic member 30 can elastically press the temperature sensing member 20 well, thereby improving the contact stability between the temperature sensing member 20 and the compressor body 200.

[0061] like Figure 1 and Figure 8 As shown, in some embodiments of the present invention, a connector 40 is provided in the cover 10, and the temperature sensor assembly 100 also includes a wiring harness, which is electrically connected to the connector 40, and the connector 40, the wiring harness and the cover 10 are injection molded twice; in this way, the sealing performance of the temperature sensor assembly 100 can be improved, thereby improving the working stability of the temperature sensor assembly 100.

[0062] Specifically, the cover 10 can be injection molded in one step, and the connector 40 is arranged in the cover 10 and electrically connected to the temperature sensing component 20 in the accommodating groove 12. In combination with the above, the main body 21 of the temperature sensing component 20 is arranged in the accommodating groove 12, and the elastic component 30 is arranged on the outer surface of the main body 21, and the elastic component 30 is provided with an avoidance structure 333, so that the first terminal 22 is conveniently passed through the avoidance structure 333 to be electrically connected to the main body 21 of the elastic component 30 and the connector 40 respectively, and the connector 40 can also be electrically connected to the wiring harness to connect to external functional devices such as power supply and / or controller; subsequently, the connector 40, the wiring harness and the cover 10 can be injection molded in a second step, so that the assembly stability of the connector 40, the wiring harness and the cover 10 can be improved, and the sealing performance of the temperature sensor assembly 100 can be improved, so as to avoid the external environment from polluting the components inside the temperature sensor assembly 100, thereby improving the working stability of the temperature sensor assembly 100.

[0063] In some embodiments of the present invention, the elastic part 30 is integrally formed with the inner wall surface of the accommodating groove 12 through a melting process. In this way, the connection stability between the elastic part 30 and the cover 10 can be improved, and the elastic part 30 can be prevented from moving relative to the cover 10, resulting in the elastic part 30 being unable to elastically press against the temperature sensing part 20 well, resulting in poor contact between the temperature sensing part 20 and the compressor body 200.

[0065] In addition, in some specific examples of the present invention, after the connector 40, the wiring harness and the cover 10 are connected, a plastic shell can be formed on the outside of the cover 10 through secondary injection molding. The plastic shell can fix the connector 40, the wiring harness and the cover 10. The plastic shell can be provided with a mounting hole 50 and connected to the compressor body 200 through fasteners.

[0067] The temperature sensor assembly 100 is provided on the compressor body 200 , and the temperature of the compressor body 200 is sensed by applying the aforementioned temperature sensor assembly 100 , thereby taking protective action according to the working state of the compressor body 200 to avoid damage to the compressor 1000 .

[0068] Specifically, the elastic member 30 and the main body 21 of the temperature sensing member 20 are disposed within the receiving groove 12 of the housing 10. The mating surface 11 of the housing 10 is mated and connected to the compressor body 200. The housing 10 is assembled on the compressor body 200 through the mounting hole 50. The opening 13 of the housing 10 faces the compressor body 200. The first elastic portion 31 of the elastic member 30 elastically presses the temperature sensing member 20 toward the opening 13, allowing the temperature sensing end 23 of the temperature sensing member 20 to come into close contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensing member 20 on the compressor body 200. Furthermore, a second elastic portion 32 of the elastic member 30 is disposed outside the mating surface 11. In the installed state, the second elastic portion 32 is elastically deformed by the pressure from the mating surface 11 and the compressor body 200, thereby sealing the gap between the mating surface 11 and the compressor body 200, thereby improving the sealing performance of the compressor 1000.

[0069] Furthermore, in the free state of the temperature sensor assembly 100, the maximum dimension of the main body 21 along the axis of the opening 13 is H1, the maximum depth dimension of the accommodating groove 12 along the axis of the opening 13 is H2, the minimum thickness 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, satisfying the relationship H2 + H3 < H1 + H4. In this way, the first elastic portion 31 of the elastic member 30 in the installed state can elastically press the temperature sensor 20 toward 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. Furthermore, the relationship H1 < H2 + H3 is also satisfied, preventing the temperature sensor 20 from being crushed in the installed state.

[0070] Furthermore, the elastic member 30 includes a peripheral wall portion 33, which is disposed between the inner circumferential surface of the receiving groove 12 and the temperature sensing member 20. The peripheral wall portion 33 protects the temperature sensing member 20 from contact with the inner circumferential surface of the receiving groove 12, thereby preventing damage. The peripheral wall portion 33 includes at least two circumferentially distributed peripheral wall portions, with an escape structure 333 formed between two adjacent peripheral wall portions 33 to avoid the first terminal 22. This allows the first terminal 22 to pass through the escape structure 333 to electrically connect to the connector 40 within the housing 10. The connector 40 can be connected to a wiring harness, which is connected to an external power supply and / or controller, and other functional devices, to transmit temperature sensing signals from the temperature sensing member 20 and to power the temperature sensing member 20.

[0071] Furthermore, the peripheral wall portion 33 includes a first wall portion 331 and a second wall portion 332, and the second wall portion 332 protrudes 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, and the outer peripheral surface of the second portion 212 protrudes from the outer peripheral surface of the first portion 211; the inner peripheral surface of the accommodating groove 12 is provided with a first surface 121 and a second surface 122, and the first surface 121 protrudes from the second surface 122 toward the inside of the accommodating groove 12, so that in the temperature sensing assembly 10 0, the first portion 211 of the temperature sensing member 20 and the first surface 121 of the accommodating groove 12 can elastically press against the first wall portion 331 of the elastic member 30, and the second portion 212 of the temperature sensing member 20 and the second surface 122 of the accommodating groove 12 can elastically press against the second wall portion 332 of the elastic member 30, so that the temperature sensing member 20 and the elastic member 30 can be more stably arranged on the cover 10, thereby making the temperature sensing member 20 more stably contact with the compressor body 200, thereby improving the temperature sensing effect of the temperature sensor assembly 100.

[0072] like Figure 9 As shown, in some embodiments of the present invention, the compressor 1000 also includes a terminal assembly 300, the terminal assembly 300 includes a seat body, a second terminal and a second wiring harness, the seat body is arranged on the outer surface of the compressor body 200, and is integrally formed with the cover 10, the second terminal is arranged inside the seat body, and is used to be electrically connected to the compressor body 200, the second wiring harness is connected to the second terminal, and is used to connect to the power supply; in this way, the terminal assembly 300 can be integrated with the temperature sensor assembly 100 to improve assembly efficiency.

[0073] Specifically, the base of the terminal assembly 300 is integrally formed with the cover shell 10. For example, the cover shell 10, the wiring harness and the connector 40 are secondary injection molded so that the base of the terminal assembly 300 is formed on the outside of the cover shell 10. A second terminal and a second wiring harness are provided in the base. The second terminal can be electrically connected to the metal column extending from the compressor body 200. The second terminal is connected to the wiring harness, and the wiring harness can be connected to an external power supply to supply power to the compressor body 200. The base of the terminal assembly 300 is integrally formed with the cover shell 10 of the temperature sensor assembly 100, which can improve the assembly efficiency of the compressor 1000.

[0074] In some embodiments of the present invention, the terminal assembly 300 further includes a sealant, which is disposed between the base and the outer surface of the compressor body 200 and is used to seal the gap between the base and the compressor body 200. This improves the sealing performance of the terminal assembly 300 and prevents the external environment from contaminating the interior of the terminal assembly 300, which could cause functional components to malfunction. Furthermore, the sealant is integrally formed with the elastic member 30. Thus, during assembly, the sealant and the second elastic portion 32 of the elastic member 30 can respectively seal the gap between the base and the cover 10 and the compressor body 200, thereby improving assembly efficiency and sealing performance.
