[0044] 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.

[0045] 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.

[0046] like Figure 2 and Figure 3 As shown, the pressure sensing component according to the embodiment of the utility model comprises: a pressure sensing component 10 and a support component 20. The pressure sensing component 10 is the main part of the pressure sensing component, which is mainly used to sense pressure and can sense the pressure of the medium. The support component 20 mainly plays the role of installation and support.

[0047] like Fig. 9 and Fig.10 As shown, the support member 20 is provided with a main body 21 and a limiting part 22. The limiting part 22 is provided on the main body 21. The main body 21 is suitable for supporting the pressure sensing part 10, that is, the main body 21 contacts and cooperates with the bottom surface of the pressure sensing part 10, and the limiting part 22 is suitable for limiting and cooperating with the outer side surface of the pressure sensing part 10. Among them, the main body 21 is the main body 21 of the support member 20, which mainly plays the role of support and installation, and the limiting part 22 is mainly used to limit the movement of the pressure sensing part 10 in its plane. It can be understood that the support member 20 can be an integrally formed part.

[0048] The main body 21 contacts and cooperates with the bottom surface of the pressure sensing element 10, that is, when the sensor 1 is press-fitted, the bottom surface of the pressure sensing element 10 is pressed against the main body 21. Moreover, the limiting portion 22 is limited and cooperates with the outer side surface of the pressure sensing element 10, so that the limiting portion 22 can be used to limit the outer side surface of the pressure sensing element 10 to prevent the pressure sensing element 10 from being greatly offset or rotated during the installation process, thereby affecting the transmission of the signal, so that the pressure sensing element 10 can work better.

[0049] It should be noted that the limiting portion 22 is arranged to protrude toward the pressure sensing element 10 relative to the main body 21 , so that the outer side surface of the pressure sensing element 10 will only contact the limiting portion 22 but not the corresponding main body 21 .

[0050] Furthermore, if Figure 3As shown, a first ridge 12 is defined between the bottom surface of the pressure sensing element 10 and the outer side surface of the pressure sensing element 10, and a contact point that contacts the main body 21 or the limiting portion 22 is provided on the first ridge 12, and any contact point does not contact the main body 21 and the limiting portion 22 at the same time. It can be understood that the first ridge 12 is defined between the bottom surface and the outer side surface of the pressure sensing element 10, and the first ridge 12 is formed by a plurality of points, at least some of which are in contact with the main body 21 or the limiting portion 22, and these points are contact points, and any contact point does not contact the main body 21 and the limiting portion 22 at the same time. In other words, a plurality of contact points are arranged on the first edge 12, some of which may be in contact with the main body 21 only but not in contact with the limiting portion 22, some of which may be in contact with the limiting portion 22 only but not in contact with the main body 21, all of which may be in contact with the main body 21 only but not in contact with the limiting portion 22, or all of which may be in contact with the limiting portion 22 only but not in contact with the main body 21. In this way, it is avoided that the same contact point is in contact with the main body 21 and the limiting portion 22 at the same time, resulting in greater stress at the contact point position, which may damage the pressure sensing component 10 and affect the service life of the pressure sensing component 10.

[0051] Therefore, any contact point on the first edge 12 does not contact the main body 21 and the limiting portion 22 at the same time. In this way, when the pressure sensing component 10 is installed on the support component, the same contact point either contacts only the main body 21 or contacts only the limiting portion 22. In this way, the stress between the support component 20 and the pressure sensing component 10 can be reduced, thereby protecting the sensor 1 and limiting the pressure sensing component 10 to prevent the pressure sensing component 10 from a large displacement or rotation during the installation process, so that the pressure sensing component 10 can work better.

[0052] The contact points include: first-part contact points and second-part contact points. The bottom surface of the pressure sensing component 10 is formed with first-part contact points, which are in contact with the main body 21. The outer side surface of the pressure sensing component 10 forms second-part contact points, which are in contact with the limiting portion 22. It can be understood that both the first-part contact points and the second-part contact points are located on the first edge 12 defined by the bottom surface of the pressure sensing component 10 and the outer side surface of the pressure sensing component 10. That is, the first-part contact points are only in contact with the main body 21 and not in contact with the limiting portion 22, while the second-part contact points are only in contact with the limiting portion 22 and not in contact with the main body 21. In this way, the same contact point can be in contact with either the main body 21 or the limiting portion 22, thereby reducing the stress between the support 20 and the pressure sensing component 10 and protecting the sensor 1.

[0053] In addition, if Fig. 9 and Fig.10As shown, the main body 21 includes a contact surface 211, and the inner wall surface of the limiting portion 22 is formed as a limiting surface 222. The contact surface 211 contacts and cooperates with the bottom surface of the pressure sensing component 10, and the limiting surface 222 cooperates with the outer side surface of the pressure sensing component 10. Among them, the contact surface 211 and the limiting surface 222 can both play the role of limiting installation. The contact surface 211 is formed on the main body 21, and the second limiting portion 22 is formed on the inner wall surface of the limiting portion 22. In this way, when the pressure sensing component 10 is installed with the support member 20, the bottom surface of the pressure sensing component 10 can be pressed against the contact surface 211, and the limiting surface 222 will cooperate with the outer wall surface of the pressure sensing component 10, so that the pressure sensing component 10 can be limited to prevent the pressure sensing component 10 from having a large offset or rotation during the installation process, thereby affecting the transmission of the signal.

[0054] In addition, if Fig. 9 and Fig.10 As shown, there are multiple limiting parts 22, and the multiple limiting parts 22 are arranged at intervals in the circumferential direction of the main body 21, so that the multiple limiting parts 22, that is, the multiple second abutting surfaces 222, respectively limit the outer side surfaces on different sides of the pressure sensing component 10. Among them, multiple limiting parts 22 are provided, so that the limiting points between the support member 20 and the pressure sensing component 10 can be increased, so that the pressure sensing component 10 can be limited at multiple positions, and the multiple limiting surfaces 222 respectively limit the outer side surfaces on different sides of the pressure sensing component 10 to limit the movement of the pressure sensing component 10 in different directions.

[0055] Furthermore, if Fig.10 As shown, the limiting portion 22 is also provided with a guide surface 221, and the guide surface 221 is connected to the end of the limiting surface 222 away from the contact surface 211. Among them, the guide surface 221 mainly plays a guiding role. The guide surface 221 is connected to the end of the limiting surface 222 away from the contact surface 211, so that in the process of installing and matching the pressure sensing component 10 with the contact surface 211, the guide surface 221 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, by guiding the pressure sensing component 10 by the guide surface 221, the installation speed of the pressure sensing component 10 can also be accelerated, and it is also easier to achieve automated installation.

[0056] Specifically, Fig.10As shown, in the direction away from the limiting surface 222, the guide surface 221 is gradually inclined outward. This arrangement is more reasonable. In the direction away from the limiting surface 222, the guide surface 221 is gradually inclined outward, so that the side of the guide surface 221 away from the limiting surface 222 is easier to cooperate with the pressure sensing component 10, which is convenient for the installation of the pressure sensing component 10. In the process of the pressure sensing component 10 moving toward the contact surface 211, the guide surface 221 will gradually guide the pressure sensing component 10 until the bottom surface and the outer side surface of the pressure sensing component 10 cooperate with the contact surface 211 and the limiting surface 222 respectively.

[0057] In addition, if Fig.10 As shown, the main body 21 is provided with an escape portion 212 , which is a recessed groove, a through hole or an opening, and the escape portion 212 is arranged opposite to the limiting portion 22 .

[0058] The avoidance portion 212 mainly plays the role of avoidance, and is arranged opposite to the limiting portion 22, so that different positions on the first edge 12 of the pressure sensing component 10 will only contact the limiting surface 222 or the contact surface 211 respectively, that is, the same position of the first edge 12 will not contact the limiting portion 22 and the main body 21 at the same time, which can also reduce the stress of the pressure sensing component 10 on the support member 20. In addition, the setting of the limiting portion 22 can be facilitated, so as to improve the structural strength of the limiting portion 22.

[0059] It should be noted that the avoidance portion 212 is disposed on a contact surface 211 of the main body 21 close to the bottom surface of the pressure sensing element 10 , and the orthographic projection position of the limiting portion 22 on the contact surface 211 of the main body 21 is the position of the avoidance portion 212 .

[0060] It is understandable that the avoidance portion 212 may be a groove, a through hole, or an opening, wherein the groove is Fig.10 The recessed groove shown has an opening facing upward, the through hole may be a through hole that passes through the main body 21 from the contact surface 211, and the opening may be a groove or a notch that opens in other directions.

[0061] According to some embodiments of the present invention, Fig.10As shown, the avoidance portion 212 is a sink, and part of the limiting portion 22 is located in the sink, and at least the outer side of the limiting portion 22 facing the pressure sensing component 10 is spaced apart from the corresponding side wall of the sink. For example, the limiting surface 222 of the limiting portion 22 is spaced apart from the side wall of the sink adjacent to the center of the main body 21. When the outer side of the pressure sensing component 10 contacts the limiting surface 222, the first edge 12 of the pressure sensing component 10 corresponding to the part of the sink is suspended, so that any point on the first edge 12 will not contact the limiting surface 22 and the contact surface 211 at the same time, thereby avoiding stress concentration between the support 20 and the pressure sensing component 10, so as to increase the protection of the pressure sensing component 10. In addition, it is also possible to avoid interference between the outer side of the pressure sensing component 10 and the side wall corresponding to the sink.

[0062] Optionally, the contact points include a third part of contact points, the third part of contact points are in contact with the main body 21, and any contact point is not in contact with the limiting portion 22. For example, when the limiting portion 22 is a small round convex point, the limiting portion 22 is not in contact with the first edge 12, and of course, some points on the first edge 12 are allowed to be neither in contact with the main body 21 nor in contact with the limiting portion 22. Therefore, it can also be achieved that any contact point is not in contact with the main body 21 and the limiting portion 22 at the same time, which can reduce contact stress.

[0063] Optionally, the contact points include a fourth part of contact points, the fourth part of contact points are in contact with the limiting portion 22, and any contact point is not in contact with the main body 21. For example: when a bracket is provided on the contact surface 211 of the main body 21 to support the pressure sensing element 10, the main body 21 may not contact any point on the first edge 12, and the limiting portion 22 is in contact with the first edge 12. Of course, it is allowed that some points on the first edge 12 are not in contact with the main body 21 or the limiting portion 22. Therefore, it is also possible to achieve that any contact point is not in contact with the main body 21 and the limiting portion 22 at the same time, which can reduce the contact stress.

[0064] In addition, if Figure 7 and Fig. 9As 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 23, and the connecting spring 30 penetrates the through hole 23. Among them, the connecting spring 30 mainly plays the role of electrical connection. The through hole 23 can play the role of positioning and installation. The connecting spring 30 penetrates the through hole 23, so that the through hole 23 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 23. 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 housing 70 through the through hole 23, so that the grounding of the sensor 1 can be achieved.

[0065] Furthermore, the sensor 1 also includes a connector 90, which is disposed on a side of the pressure sensing component 10 away from the support component 20, and the connector 90 is snap-fitted with the support component 20. The connector 90 mainly serves the function of connection and installation. The connector 90 is disposed on a side of the pressure sensing component 10 away from the support component 20, that is, the connector 90 and the support component 20 are respectively located on both sides of the pressure sensing component 10, and because the connector 90 is snap-fitted with the support component 20, after the connector 90 and the support component 20 are installed, the connector 90 and the support component 20 can wrap the pressure sensing component 10, thereby avoiding interference of the external environment on the pressure sensing component 10, and the pressure sensing component 10 can work better.

[0066] Specifically, Figure 6-Figure 10 As shown, the connecting member 90 is provided with a first positioning portion 91 and a buckle 92, and the supporting member 20 is also provided with a second positioning portion 25 and a boss 26. The first positioning portion 91 is positioned and matched with the second positioning portion 25, and the buckle 92 is plugged and matched with the boss 26. Among them, the cooperation between the first positioning portion 91 and the second positioning portion 25 can play a positioning role. The first positioning portion 91 is arranged on the connecting member 90, and the second positioning portion 25 is arranged on the supporting member 20. In this way, when the connecting member 90 is installed and matched with the supporting member 20, the cooperation between the first positioning portion 91 and the second positioning portion 25 can be used to calibrate the position between the connecting member 90 and the supporting member 20, so that the installation between the connecting member 90 and the supporting member 20 can be made more accurate and fast, thereby improving the assembly efficiency.

[0067] It should be noted that the first positioning portion 91 can be a positioning column, which has a simple structure and is easy to process and set. Moreover, the buckle 92 and the first positioning portion 91 are both located on the side of the connecting member 90 facing the support member 20, which is more reasonable. In the process of the connecting member 90 and the support member 20 being engaged, the buckle 92 and the first positioning portion 91 can be more conveniently engaged with the boss 26 and the second positioning portion 25 on the support member 20, respectively. At the same time, the size of the support member 20 can be reduced to a certain extent, which is convenient for material transportation.

[0068] The sensor 1 according to the embodiment of the utility model comprises the pressure sensing component described in the above embodiment. The sensor 1 in the present application may be a temperature and pressure sensor 1, which can measure the pressure and temperature of the corresponding medium.

[0069] Furthermore, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a temperature sensing component 40, a protective cover 50 and a mounting base 60. The temperature sensing component 40 is arranged in the protective cover 50, and the temperature sensing component 40 is connected to the side of the mounting base 60 adjacent to the protective cover 50, and the mounting base 60 is matched with the protective cover 50. Among them, the temperature sensing component 40 is mainly used to sense the temperature of the medium, and the temperature sensing component 40 can be an NTC thermistor. The protective cover 50 mainly plays a protective role. The mounting base 60 mainly plays a mounting role.

[0070] 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.

[0071] 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.

[0072] In addition, if Figure 2-Figure 5As 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.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] In addition, if Figure 3 and Figure 8 As shown, the support member 20 is provided with a third positioning portion 24, and the shell 70 is provided with a fourth positioning portion 72, and the third positioning portion 24 is positioned and matched with the fourth positioning portion 72. Among them, the third positioning portion 24 and the fourth positioning portion 72 can both play a positioning role. The third positioning portion 24 is provided on the support member 20, and the fourth positioning portion 72 is provided on the shell 70. In this way, when the support member 20 is matched with the shell 70, the third positioning portion 24 and the fourth positioning portion 72 can be used to calibrate the position between the support member 20 and the shell 70, so that the installation between the support member 20 and the shell 70 can be made more accurate and fast, thereby improving the assembly efficiency.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.
