[0036] The embodiments of the present utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present utility model are described in detail below.

[0037] Reference below Figure 1-Figure 10 The pressure sensing component according to the embodiment of the utility model is described. The pressure sensing component is mainly used to sense and measure the pressure of the medium.

[0038] like Figure 2 and Figure 3 As shown, the pressure sensing assembly according to the embodiment of the utility model comprises a pressure sensing member 10 and a support member 20. The pressure sensing member 10 is mainly used to sense pressure, and the support member 20 is mainly used for installation and support.

[0039] like Fig. 9 and Fig.10As shown, the support member 20 is provided with a placement groove 21 and a matching portion 22, the matching portion 22 is provided on the side wall of the placement groove 21, the pressure sensing member 10 is suitable for being provided in the placement groove 21, and the matching portion 22 is limitedly matched with the side wall surface of the pressure sensing member 10. In this way, the pressure sensing member 10 is suitable for being provided in the placement groove 21, and the matching portion 22 is limitedly matched with the side wall surface of the pressure sensing member 10 to limit the movement of the pressure sensing member 10 in its plane, thereby avoiding the position deviation of the pressure sensing member 10 during installation and use, thereby ensuring the reliability of signal transmission.

[0040] In some embodiments of the present invention, Fig. 9 and Fig.10 As shown, a sinking groove 211 is provided on the bottom of the placement groove 21, and the matching portion 22 corresponds to the sinking groove 211. It should be noted that the matching portion 22 corresponds to the sinking groove 211, that is, the projection position of the matching portion 22 on the bottom of the placement groove 21 is the position of the sinking groove 211.

[0041] It should be noted that the pressure sensing component 10 is arranged on the placement groove 21, and the matching portion 22 is limitedly matched with the side wall surface of the pressure sensing component 10. The pressure sensing component 10 is arranged on the placement groove 21, so that the placement groove 21 can provide an installation position for the pressure sensing component 10, which is convenient for the installation and setting of the pressure sensing component 10. Moreover, the matching portion 22 is limitedly matched with the side wall surface of the pressure sensing component 10, so that the matching portion 22 can limit the movement of the pressure sensing component 10 in its plane, making the signal transmission more stable and reliable, and the pressure sensing component 10 can work better. In addition, it should be noted that after the pressure sensing component 10 is installed on the support 20, the bottom surface of the pressure sensing component 10 only contacts the bottom of the placement groove 21, and the side wall surface of the pressure sensing component 10 only contacts the matching portion 22. In addition, due to the arrangement of the sink groove 211, it is easy to ensure that any point on the edge defined between the side wall surface of the pressure sensing component 10 and the bottom surface of the pressure sensing component 10 will not contact the placement groove 21 and the matching portion 22 at the same time, that is, any point on the above-mentioned edge will not contact the bottom of the placement groove 21 and the matching portion 22 at the same time, thereby reducing the stress of the support 20 on the pressure sensing component 10 and realizing the protection of the pressure sensing component 10. In addition, it is convenient to arrange the matching portion 22, so as to improve the structural strength of the matching portion 22.

[0042] In some embodiments of the present invention, Fig.10 As shown, part of the matching portion 22 is located in the sink 211. In other words, part of the bottom of the matching portion 22 extends into the sink 211, so that the corner line of the matching portion 22 can be prevented from contacting the corner line of the pressure sensing component 10, thereby preventing the corner line of the matching portion 22 from contacting the corner line of the pressure sensing component 10, thereby preventing stress concentration from occurring when the corner line of the matching portion 22 contacts the corner line of the pressure sensing component 10, which can easily cause damage to the pressure sensing component 10.

[0043] In some embodiments of the present invention, Fig.10 As shown, at least one side of the matching portion 22 facing the pressure sensing component 10 is spaced apart from the corresponding side wall of the sink groove 211. That is to say, at least one side of the matching portion 22 that contacts the side wall of the pressure sensing component 10 is spaced apart from the corresponding side wall of the sink groove 211. When the side wall of the pressure sensing component 10 contacts the matching portion 22, the portion of the ridge defined by the side wall and the bottom of the pressure sensing component 10 corresponding to the sink groove 211 is suspended. Thus, any point on the ridge will not contact the matching portion 22 and the bottom of the placement groove 21 at the same time, thereby reducing the stress of the support member 20 on the pressure sensing component 10.

[0044] Specifically, in the circumferential direction of the pressure sensing component 10, the two opposite side walls of the matching portion 22 are spaced from the corresponding side walls of the sink 211. This can reduce the stress on the pressure sensing component 10 and facilitate the manufacture of the support component 20.

[0045] It should be noted that the matching portion 22 is protruded toward the pressure sensing component 10 relative to the side wall of the corresponding placement groove 21, so that the side wall surface of the pressure sensing component 10 will only contact the matching portion 22 and will not contact the side wall of the corresponding placement groove 21.

[0046] In some embodiments of the present invention, Fig.10 As shown, the matching portion 22 is connected to the bottom wall of the sink 211. That is, the matching portion 22 at least partially extends into the sink 211, so that the corner line of the matching portion 22 can be prevented from contacting the corner line of the pressure sensing component 10, thereby preventing the corner line of the matching portion 22 from contacting the corner line of the pressure sensing component 10, thereby preventing stress concentration from occurring when the corner line of the matching portion 22 contacts the corner line of the pressure sensing component 10, which can easily cause damage to the pressure sensing component 10. In addition, the matching portion 22 can also be fixed to make the setting of the matching portion 22 more secure and stable.

[0047] In some embodiments of the present invention, the end surface of the matching portion 22 close to the bottom of the placement groove 21 is spaced from the bottom of the groove. In other words, the matching portion 22 is arranged outside the sink groove 211 and is spaced a certain distance from the opening of the sink groove 211. In this way, the edges defined by the outer wall and the bottom surface of the pressure sensing component 10 will not contact the matching portion 22, so that the above-mentioned edges will not contact the matching portion 22 and the bottom of the placement groove 21 at the same time, thereby avoiding stress concentration and reducing the stress of the pressure sensing component 10 by the small support member 20.

[0048] In some embodiments of the present invention, Fig. 9 and Fig.10As shown, there are multiple matching parts 22, and the multiple matching parts 22 are arranged at intervals in the circumferential direction of the placement groove 21. Among them, multiple matching parts 22 are arranged, so that the limiting points between the support member 20 and the pressure sensing member 10 can be increased, so that the pressure sensing member 10 can be limited at multiple positions, which is more reasonable.

[0049] In some embodiments of the present invention, Fig.10 As shown, the matching portion 22 is provided with a limiting surface 221 and a guiding surface 222, the limiting surface 221 is limitedly matched with the outer wall surface of the pressure sensing component 10, and the guiding surface 222 is connected to an end of the limiting surface 221 away from the bottom of the placement groove 21, so as to guide the assembly of the pressure sensing component 10. Among them, the limiting surface 221 mainly plays a limiting role, and the guiding surface 222 mainly plays a guiding role.

[0050] The guide surface 222 is connected to the end of the limiting surface 221 away from the bottom of the placement groove 21, so that during the installation of the pressure sensing component 10 and the support component 20, the guide surface 222 will guide the pressure sensing component 10, thereby improving the accuracy of the installation of the pressure sensing component 10 and improving the assembly efficiency. Moreover, through the guidance of the guide surface 222 to the pressure sensing component 10, the installation speed of the pressure sensing component 10 can also be accelerated, and it is also easier to achieve automated installation.

[0051] In some embodiments of the present invention, Fig. 9 and Fig.10 As shown, the pressure sensing component 10 is non-circular, and an edge is defined between the two side walls of the pressure sensing component 10. The support member 20 is provided with a avoidance opening 23 at the position corresponding to the edge. When there are multiple edges, multiple avoidance openings 23 can be provided. Among them, the avoidance openings 23 mainly play the role of avoidance. By providing multiple avoidance openings 23, the avoidance openings 23 can avoid the edge defined between the two side walls of the pressure sensing component 10. In this way, the stress on the pressure sensing component 10 can be further reduced, and a larger pressure sensing component 10 can be accommodated without increasing the size of the support member 20.

[0052] In some embodiments of the present invention, the pressure sensing element 10 is a ceramic element. That is, the circuit board in the pressure sensing element 10 can be a ceramic circuit board, which can better adapt to the environment to perform pressure detection on media such as refrigerants, and the above-mentioned stress reduction measures make the ceramic circuit board less likely to be damaged.

[0053] The sensor 1 according to the embodiment of the utility model includes the pressure sensing component described in the above embodiment. The sensor 1 in the present application can be a temperature and pressure sensor 1, which can measure the pressure and temperature of the corresponding medium, or a pressure sensor, which can measure the pressure of the corresponding medium.

[0054] In addition, if Figure 7 and Fig. 9 As shown, the sensor 1 also includes a connecting spring 30, which is connected to the side of the pressure sensing member 10 adjacent to the support member 20, and the support member 20 is provided with a through hole 24, and the connecting spring 30 penetrates the through hole 24. Among them, the connecting spring 30 mainly plays the role of electrical connection. The through hole 24 can play the role of positioning and installation. The connecting spring 30 penetrates the through hole 24, so that the through hole 24 has a positioning effect on the connecting spring 30, which can improve the accuracy of the assembly of the pressure sensing member 10, and can also protect the connecting spring 30 to a certain extent. Therefore, the connecting spring 30 is connected to the side of the pressure sensing member 10 adjacent to the support member 20, which is more reasonable and convenient for the connecting spring 30 to cooperate with the through hole 24. It should be noted that in order to make the sensor 1 work more safely, the sensor 1 needs to be grounded. Specifically, the connecting spring 30 can be electrically connected to the shell 70 through the through hole 24, so that the grounding of the sensor 1 can be achieved.

[0055] Furthermore, if Figure 2 and Figure 3 As shown, the sensor 1 further includes a temperature sensing element 40, a protective cover 50 and a mounting base 60. The temperature sensing element 40 is disposed in the protective cover 50, and the temperature sensing element 40 is connected to a side of the mounting base 60 adjacent to the protective cover 50, and the mounting base 60 is matched with the protective cover 50. The temperature sensing element 40 is mainly used to sense the temperature of the medium, and the temperature sensing element 40 can be an NTC thermistor. The protective cover 50 mainly plays a protective role. The mounting base 60 mainly plays a mounting role.

[0056] The temperature sensing element 40 is arranged in the protective sleeve 50, so that the protective sleeve 50 can be used to protect the temperature sensing element 40, and the medium can be prevented from directly impacting the temperature sensing element 40, so that the temperature sensing element 40 can work better. The temperature sensing element 40 is connected to the side of the mounting base 60 adjacent to the protective sleeve 50, so that the temperature sensing element 40 can be fixed, so that the setting of the temperature sensing element 40 is more reliable and stable, so that the temperature sensing element 40 can work better. It is also convenient for the temperature sensing element 40 to be installed and matched with the protective sleeve 50, so that the protective sleeve 50 can protect the temperature sensing element 40.

[0057] It should be noted that, since the temperature sensing element 40 is mounted on the mounting base 60, the mounting base 60 is matched with the protective cover 50. This arrangement is more reasonable, and while the mounting base 60 and the protective cover 50 are installed and matched, it is convenient for the temperature sensing element 40 to match with the protective cover 50. Both the first limiting portion and the second limiting portion 51 can play a limiting role.

[0058] In addition, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a shell 70, the pressure sensing component 10 and the support component 20 are both arranged in the shell 70, a first limiting portion is arranged on the shell 70, a second limiting portion 51 is arranged on the protective cover 50, and a third limiting portion 61 is arranged on the mounting base 60, and the second limiting portion 51 and the third limiting portion 61 are respectively limited and matched with the first limiting portion. Among them, the shell 70 mainly plays the role of installation and matching. The pressure sensing component 10 and the support component 20 are both arranged in the shell 70, so that the support component 20 can be fixed, making the arrangement of the support component 20 more reliable and stable, so that the pressure sensing component 10 can be better supported, and the pressure sensing component 10 can work better.

[0059] The first limiting part, the second limiting part 51 and the third limiting part 61 can all play a limiting role. The first limiting part is arranged on the shell 70, and the second limiting part 51 is arranged on the protective cover 50. In this way, when the protective cover 50 and the shell 70 are installed, the first limiting part and the second limiting part 51 cooperate to install more accurately, and the protective cover 50 can be prevented from rotating relative to the shell 70, so that the sensor 1 can work better. Similarly, the third limiting part 61 is arranged on the mounting base 60, and the first limiting part is arranged on the shell 70. In this way, when the mounting base 60 and the shell 70 are installed, the first limiting part and the third limiting part 61 cooperate to install more accurately, and the mounting base 60 can be prevented from rotating relative to the shell 70, so that the sensor 1 can work better.

[0060] In addition, if Figure 5 As shown, in the axial direction, the second limiting portion 51 is aligned with the third limiting portion 61. The second limiting portion 51 is aligned with the third limiting portion 61. As can be seen from the above, the second limiting portion 51 and the third limiting portion 61 are both matched with the first limiting portion. Therefore, the second limiting portion 51 is aligned with the third limiting portion 61, which can facilitate the second limiting portion 51 and the third limiting portion 61 to be matched with the first limiting portion at the same time. After the second limiting portion 51 and the third limiting portion 61 are matched with the first limiting portion, the position between the protective cover 50 and the mounting base 60 can also be kept relatively stable, so that the temperature sensing component can be kept relatively stable, and the sensor 1 can work better.

[0061] Furthermore, if Figure 3As shown, a step portion 71 is provided in the shell 70, and the protective sleeve 50 is also provided with a matching surface 52. In the first axial direction, the matching surface 52 is limitedly matched with the surface of the step portion 71. A protective member 62 is provided at one end of the mounting base 60 away from the protective sleeve 50. In the second axial direction, the protective member 62 is abutted and matched with the pressure sensing member 10. The second axial direction is opposite to the first axial direction. Among them, both the step portion 71 and the matching surface 52 can play a limiting role. The step portion 71 is provided in the shell 70, and the matching surface 52 is provided on the protective sleeve 50. In this way, when the protective sleeve 50 is installed on the shell 70, the step portion 71 and the matching surface 52 can be used to limit the protective sleeve 50 in the axial direction. Therefore, the installation of the protective sleeve 50 can be more accurate, the assembly efficiency is improved, and the setting of the protective sleeve 50 can also be made more stable.

[0062] The protective member 62 mainly plays a protective role. The protective member 62 is set at one end of the mounting base 60 away from the protective sleeve 50, so that in the second axial direction, the protective member 62 can abut against the pressure sensing member 10, so that the protective member 62 can be used to eliminate the gap between the pressure sensing member 10 and the mounting base 60, thereby avoiding a collision between the pressure sensing member 10 and the mounting base 60, thereby affecting the normal use of the sensor 1. It should be noted that the second axial direction is opposite to the first axial direction. Specifically, the first axial direction is the direction of the pressure sensing member 10 toward the protective sleeve 50, and the second axial direction is the direction of the protective sleeve 50 toward the pressure sensing member 10.

[0063] Specifically, Figure 5 As shown, the second limiting portion 51 and the third limiting portion 61 are both constructed as limiting grooves, and a pressure chip 11 is provided on the side of the pressure sensing component 10 facing the mounting base 60, and the medium can contact the pressure chip 11 through the limiting groove. In other words, the second limiting portion 51 and the third limiting portion 61 are both limiting groove structures, so that the external medium can contact the pressure chip 11 through the second limiting portion 51 and the third limiting portion 61 successively, wherein the pressure chip 11 mainly processes the pressure information of the medium contacted by the pressure sensing component 10. The pressure chip 11 is arranged on the side of the pressure sensing component 10 facing the mounting base 60, which is more reasonable and can shorten the time required for the medium to contact the pressure chip 11, thereby improving the response speed of the sensor 1.

[0064] In addition, if Figure 2 and Figure 3As shown, the sensor 1 also includes a sealing member 80, which is spaced apart from the mounting base 60, and the sealing member 80 is sealingly disposed between the pressure sensing member 10 and the housing 70. Among them, the sealing member 80 mainly plays a sealing role. It should be noted that the sealing member 80 is sleeved on the mounting base 60, so the sealing member 80 is spaced apart from the mounting base 60, that is, there is a gap between the sealing member 80 and the mounting base 60, which facilitates the installation of the sealing member 80. Moreover, the sealing member 80 is sealingly disposed between the pressure sensing member 10 and the housing 70, so that the sealing member 80 can seal the gap between the pressure sensing member 10 and the housing 70. The sealing member 80 can be a sealing ring.

[0065] In addition, if Figure 2 and Figure 8 As shown, the support member 20 is provided with a first positioning portion 25, and the housing 70 is provided with a second positioning portion, and the first positioning portion 25 is positioned and matched with the second positioning portion. Among them, the first positioning portion 25 and the second positioning portion can both play a positioning role, the first positioning portion 25 is provided on the support member 20, and the second positioning portion is provided on the housing 70, so that when the support member 20 is matched with the housing 70, the first positioning portion 25 and the second positioning portion can be used to calibrate the position between the support member 20 and the housing 70, so that the installation between the support member 20 and the housing 70 can be made more accurate and fast, thereby improving the assembly efficiency.

[0066] Furthermore, if Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the sensor 1 further includes a connecting member 90, which is in contact with the side of the pressure sensing member 10 away from the mounting base 60. The connecting member 90 mainly serves the function of connection and installation. The connecting member 90 is in contact with the side of the pressure sensing member 10 away from the mounting base 60, that is, the connecting member 90 and the supporting member 20 are respectively located on both sides of the pressure sensing member 10. The connecting member 90 is in contact with the side of the pressure sensing member 10 away from the mounting base 60, which can improve the stability of the pressure sensing member 10.

[0067] It should be noted that the seal 80 can separate the gap between the pressure sensing element 10 and the housing 70 into two areas, that is, the inside of the seal 80 is the medium contact area, and the outside of the seal 80 is the medium isolation area, and the third limit portion 61 is also a pressure inlet while limiting, and the medium can enter the medium contact area from the third limit portion 61, and then can perform contact sensing with the pressure sensing element 10. Specifically, when the sensor 1 measures the pressure of the medium, the medium can successively enter the medium contact area along the second limit portion 51 and the third limit portion 61 to perform contact sensing with the pressure sensing element 10, and the pressure sensing element 10 will transmit the corresponding signal to the connector 90 after sensing, and then output the signal to the outside of the sensor 1.

[0068] Similarly, when the sensor 1 measures the temperature of the medium, the medium can enter the protective cover 50 through the slot and contact the temperature sensing element 40. The temperature sensing element 40 transmits the sensed medium temperature signal to the pressure sensing element 10 through the mounting base 60. The pressure sensing element 10 is provided with an electrical connection hole. The medium temperature signal can be transmitted to the connector 90 along the bottom of the pressure sensing element 10 and the electrical connection hole in turn, and then the signal is output to the outside of the sensor 1. The electrical connection hole is located in the medium isolation area, which can prevent the medium from leaking through the electrical connection hole and causing damage to the internal components of the sensor 1.

[0069] As an optional embodiment, the number of electrical connection holes can be greater than or equal to four, and the hole diameter of the electrical connection hole can be one-fifth of the thickness of the pressure sensing component 10. In addition, the distance from the electrical connection hole to the edge of the pressure sensing component 10 is greater than the hole diameter of the electrical connection hole.

[0070] Specifically, Figure 6-Figure 10 As shown, the connector 90 is provided with a third positioning portion 91 and a first plug-in portion 92, and the support member 20 is also provided with a fourth positioning portion 27 and a second plug-in portion 28. The third positioning portion 91 is positioned and matched with the fourth positioning portion 27, and the first plug-in portion 92 is plug-matched with the second plug-in portion 28. Among them, the third positioning portion 91 and the fourth positioning portion 27 can both play a positioning role. The third positioning portion 91 is provided on the connector 90, and the fourth positioning portion 27 is provided on the support member 20. In this way, when the connector 90 is installed and matched with the support member 20, the third positioning portion 91 and the fourth positioning portion 27 can be used to calibrate the position between the connector 90 and the support member 20, so that the installation between the connector 90 and the support member 20 can be more accurate and fast, thereby improving the assembly efficiency.

[0071] Both the first plug-in portion 92 and the second plug-in portion 28 can play a plug-in role. The first plug-in portion 92 is arranged on the connector 90, and the second plug-in portion 28 is arranged on the support member 20. In this way, when the connector 90 and the support member 20 are installed and matched, the first plug-in portion 92 can be plugged and matched with the second plug-in portion 28, so that the connection between the connector 90 and the support member 20 can be more stable. It should be noted that after the connector 90 and the support member 20 are installed, they can wrap the pressure sensing member 10 located in the middle to a certain extent, so as to avoid contact between the pressure sensing member 10 and the housing 70, thereby avoiding damage to the pressure sensing member 10 during the press-fitting process, and ensuring the effective connection between the connector 90 and the pressure sensing member 10.

[0072] As an optional embodiment, the pressure sensing element 10 is a ceramic element. That is, the circuit board in the pressure sensing element 10 can be a ceramic circuit board, which can better prevent the sensor 1 from causing damage to the circuit board during installation compared to a flexible circuit board. Moreover, when the pressure sensing element 10 presses the sealing element 80, the ceramic material can better press the sealing element 80, thereby ensuring the sealing of the sensor 1.

[0073] As an optional embodiment, the housing 70 and the connector 90 may be fixed by riveting, which can ensure the sealing of the seal 80. At the same time, RTV glue may be applied around the riveting position to prevent external water vapor from entering the sensor 1 and damaging the pressure sensing element 10.

[0074] It should be noted that the connector 90, the pressure sensing component 10 and the support component 20 can form a detection unit, which can protect the pressure sensing component, prevent the pressure sensing component 10 from colliding with the housing 70, and effectively ensure the connection between the pressure sensing component 10 and the connector 90 to ensure that their communication function is normal. The temperature sensing component 40, the protective cover 50, and the mounting base 60 can form a temperature sensing unit. The temperature sensing unit and the detection unit are placed in the housing 70 in sequence, which can reduce the installation steps of the process and improve production efficiency.
