DETAILED DESCRIPTION
[0054] The following describes in detail embodiments of the present application, and the embodiments described with reference to the accompanying drawings are exemplary.
[0055] The pressure sensing assembly 2 according to an embodiment of the present application will be described below with reference to Figures 1 to 15. The pressure sensing assembly 2 is mainly used to sense and measure the pressure of a medium.
[0056] As shown in Figures 2 and 3 , the pressure sensing assembly 2 according to an embodiment of the present application includes a pressure sensing element 10 and a support member 20. The pressure sensing element 10 is the main component of the pressure sensing assembly 2 and is primarily used to sense pressure, specifically the pressure of a medium. The support member 20 primarily serves as a mounting and support mechanism.
[0057] As shown in Figures 9 and 10, the support member 20 comprises a main body 21 and a stopper 22. The stopper 22 is disposed on the main body 21, and the main body 21 is adapted to support the pressure-sensing element 10. Specifically, the main body 21 contacts and engages with the bottom surface of the pressure-sensing element 10, while the stopper 22 engages and engages with the outer surface of the pressure-sensing element 10. The main body 21 is the main portion of the support member 20, primarily providing support and mounting, while the stopper 22 is primarily used to restrict the movement of the pressure-sensing element 10 within its plane. It is understood that the support member 20 may be a one-piece molded component.
[0058] 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-assembled, the bottom surface of the pressure-sensing element 10 is pressed tightly against the main body 21. Furthermore, the limiting portion 22 cooperates with the outer side surface of the pressure-sensing element 10 to limit the outer side surface of the pressure-sensing element 10. This allows the limiting portion 22 to limit the outer side surface of the pressure-sensing element 10, preventing the pressure-sensing element 10 from significantly deflecting or rotating during installation, which could affect signal transmission, thereby allowing the pressure-sensing element 10 to function better.
[0059] It should be noted that the limiting portion 22 is protruding relative to the main body 21 toward the pressure sensing element 10 , so that the outer side of the pressure sensing element 10 will only contact the limiting portion 22 but not the corresponding main body 21 .
[0060] Furthermore, as shown in Figures 3 and 13-15, 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. Contact points 13 (also referred to as contact portions, i.e., these contact points can be divided into different partial contact points based on their contact with different parts, such as the first partial contact point, the second partial contact point, etc., hereinafter) are provided on the first ridge 12 for contact with the main body 21 or the limiting portion 22. No single contact point 13 is in simultaneous contact with both the main body 21 and the limiting portion 22. It is understandable that the first ridge 12 is defined between the bottom surface and the outer side surface of the pressure-sensing element 10. 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. These points are the contact points 13, and no single contact point 13 is in simultaneous contact with both the main body 21 and the limiting portion 22. In other words, the first edge 12 is provided with a plurality of contact points 13, some of which may be in contact only with the main body 21 and not with the limiting portion 22, some of which may be in contact only with the limiting portion 22 and not with the main body 21, all of which may be in contact only with the main body 21 and not with the limiting portion 22, or all of which may be in contact only with the limiting portion 22 and not with the main body 21. This prevents the same contact point 13 from contacting both the main body 21 and the limiting portion 22 simultaneously, thus preventing the generation of significant stress at the location of the contact point 13 that could damage the pressure sensing element 10 and shorten its service life.
[0061] Thus, since no contact point 13 on the first edge 12 contacts both the main body 21 and the stopper 22 simultaneously, when the pressure sensing element 10 is mounted on the support member, the same contact point 13 contacts either only the main body 21 or only the stopper 22. This reduces the stress between the support member 20 and the pressure sensing element 10, thereby protecting the sensor 1. Furthermore, the pressure sensing element 10 can be positioned to prevent significant displacement or rotation during installation, allowing the pressure sensing element 10 to function better.
[0062] The contact point 13 includes a first contact point 131 and a second contact point 132, as shown in Figure 13. The first contact point 131 is formed on the bottom surface of the pressure-sensing element 10, contacting the main body 21. The second contact point 132 is formed on the outer side of the pressure-sensing element 10, contacting the stopper 22. It is understood that both the first contact point 131 and the second contact point 132 are located on the first edge 12 defined by the bottom and outer side of the pressure-sensing element 10. In other words, the first contact point 131 contacts only the main body 21 and not the stopper 22, while the second contact point 132 contacts only the stopper 22 and not the main body 21. This allows the same contact point 13 to contact either the main body 21 or the stopper 22, reducing stress between the support member 20 and the pressure-sensing element 10 and protecting the sensor 1.
[0063] In addition, as shown in Figures 9 and 10, 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 element 10, while the limiting surface 222 cooperates with the outer surface of the pressure-sensing element 10. Both the contact surface 211 and the limiting surface 222 can serve as a limiting installation function. The contact surface 211 is formed on the main body 21, and the limiting surface 222 is formed on the inner wall surface of the limiting portion 22. Thus, when the pressure-sensing element 10 is installed with the support member 20, the bottom surface of the pressure-sensing element 10 can be pressed against the contact surface 211, and the limiting surface 222 cooperates with the outer wall surface of the pressure-sensing element 10 to limit the pressure-sensing element 10, thereby limiting the pressure-sensing element 10 and preventing it from deviating or rotating significantly during installation, which could affect signal transmission.
[0064] 9 and 10 , there are multiple limiting portions 22, which are spaced apart in the circumferential direction of the main body 21, so that the multiple limiting portions 22, i.e., the multiple limiting surfaces 222, respectively limit the outer side surfaces of the pressure sensing element 10 on different sides. The provision of multiple limiting portions 22 increases the number of limiting points between the support member 20 and the pressure sensing element 10, thereby allowing the pressure sensing element 10 to be limited at multiple locations. The multiple limiting surfaces 222 respectively limit the outer side surfaces of the pressure sensing element 10 on different sides, thereby limiting the movement of the pressure sensing element 10 in different directions.
[0065] Furthermore, as shown in FIG10 , the limiting portion 22 is further 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 through 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.
[0066] Specifically, as shown in Figure 10, the guide surface 221 is gradually tilted outward in the direction away from the limiting surface 222. This arrangement is more reasonable. In the direction away from the limiting surface 222, the guide surface 221 is gradually tilted outward. In this way, the side of the guide surface 221 away from the limiting surface 222 is more easily matched with the pressure sensing component 10, which facilitates the installation of the pressure sensing component 10. During 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 outer side surface of the pressure sensing component 10 respectively match the contact surface 211 and the limiting surface 222.
[0067] In addition, as shown in FIG. 10 , a relief portion 212 is provided on the main body 21 . The relief portion 212 is a recessed groove, a through hole, or an opening. The relief portion 212 is disposed opposite to the limiting portion 22 .
[0068] The avoidance portion 212 primarily serves as a relief mechanism and is disposed opposite the limiting portion 22. This ensures that different locations on the first edge 12 of the pressure-sensing element 10 only contact the limiting surface 222 or the contact surface 211, respectively. That is, the same location on the first edge 12 will not simultaneously contact the limiting portion 22 and the main body 21. This also reduces the stress exerted by the pressure-sensing element 10 on the support member 20. Furthermore, this facilitates the placement of the limiting portion 22, thereby improving its structural strength.
[0069] It should be noted that the avoidance portion 212 is provided on the 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 .
[0070] It can be understood that the avoidance portion 212 can be a groove, a through hole or an opening, wherein the groove is a groove with an upward opening as shown in Figure 10, the through hole can be a through hole passing through the main body 21 from the contact surface 211, and the opening can be a groove or notch with an opening facing other directions.
[0071] According to some embodiments of the present application, as shown in FIG10 , the avoidance portion 212 is a recessed groove, and a portion of the limiting portion 22 is located within the recessed groove. At least the outer side surface of the limiting portion 22 facing the pressure-sensing component 10 is spaced apart from the corresponding sidewall of the recessed groove. For example, the limiting surface 222 of the limiting portion 22 is spaced apart from the sidewall of the recessed groove adjacent to the center of the main body 21. When the outer side surface of the pressure-sensing component 10 contacts the limiting surface 222, the portion of the first edge 12 of the pressure-sensing component 10 corresponding to the recessed groove is suspended. As a result, any contact point 13 on the first edge 12 will not contact both the limiting surface 22 and the contact surface 211 simultaneously, thereby avoiding stress concentration between the support member 20 and the pressure-sensing component 10 and increasing protection for the pressure-sensing component 10. In addition, interference between the outer side surface of the pressure-sensing component 10 and the corresponding sidewall of the recessed groove can also be avoided.
[0072] Optionally, the contact points 13 include a third portion of contact points 133, as shown in FIG14 . The third portion of contact points 133 contacts the main body 21, and no contact point 13 contacts the stopper 22. For example, when the stopper 22 is a small round protrusion, the stopper 22 does not contact the first edge 12. Of course, some contact points 13 on the first edge 12 are permitted to contact neither the main body 21 nor the stopper 22. Therefore, no contact point 13 can contact both the main body 21 and the stopper 22 simultaneously, thereby reducing contact stress.
[0073] Optionally, the contact point 13 includes a fourth portion of contact points 134, as shown in FIG15 . The fourth portion of contact points 134 contacts the limiting portion 22, and no contact point 13 contacts the main body 21. For example, when a bracket 27 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 may contact the first edge 12. Of course, some contact points 13 on the first edge 12 are allowed to contact neither the main body 21 nor the limiting portion 22. Therefore, it is possible to achieve that no contact point 13 contacts both the main body 21 and the limiting portion 22 at the same time, thereby reducing contact stress.
[0074] In addition, as shown in Figures 7 and 9, the sensor 1 also includes a connecting spring 30. The connecting spring 30 is connected to the side of the pressure sensing element 10 adjacent to the support member 20. The support member 20 is provided with a through hole 23, and the connecting spring 30 passes through the through hole 23. The connecting spring 30 primarily serves as an electrical connection. The through hole 23 also serves as a positioning and installation function. The through hole 23 provided by the connecting spring 30 positions the connecting spring 30, improving the assembly accuracy of the pressure sensing element 10 and, to a certain extent, protecting the connecting spring 30. Therefore, connecting the connecting spring 30 to the side of the pressure sensing element 10 adjacent to the support member 20 is a more reasonable arrangement, facilitating the mating of the connecting spring 30 and the through hole 23. It should be noted that to ensure safe operation of the sensor 1, it is necessary to ground the sensor 1. Specifically, the connecting spring 30 can be electrically connected to the housing 70 through the through hole 23, thereby achieving grounding of the sensor 1.
[0075] Furthermore, the sensor 1 also includes a connector 90, which is arranged on the 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 plays the role of connection and installation. The connector 90 is arranged on the 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. Since 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 preventing the external environment from affecting the pressure sensing component 10 and allowing the pressure sensing component 10 to work better.
[0076] Specifically, as shown in Figures 6 to 10, the connector 90 is provided with a first positioning portion 91 and a buckle 92, and the support member 20 is further 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. 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 provided on the connector 90, and the second positioning portion 25 is provided on the support member 20. In this way, when the connector 90 is installed and matched with the support 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 connector 90 and the support member 20, so that the installation between the connector 90 and the support member 20 can be made more accurate and quick, thereby improving the assembly efficiency.
[0077] It should be noted that the first positioning portion 91 can be a positioning post, which has a simple structure and is easy to process and set up. 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. This arrangement is more reasonable, so that during the process of the connecting member 90 and the support member 20 being engaged, the buckle 92 and the first positioning portion 91 can more conveniently engage 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, facilitating material transportation.
[0078] The sensor 1 according to an embodiment of the present application includes the pressure sensing component 2 of any of the above embodiments. The sensor 1 in the present application may be a temperature and pressure sensor that can measure the pressure and temperature of a corresponding medium.
[0079] Furthermore, as shown in Figures 2 and 3, the sensor 1 also includes a temperature sensing element 40, a protective sleeve 50, and a mounting base 60. The temperature sensing element 40 is disposed within the protective sleeve 50 and is connected to the mounting base 60 on a side adjacent to the protective sleeve 50. The mounting base 60 is fitted onto the protective sleeve 50. The temperature sensing element 40 is primarily used to sense the temperature of the medium and may be an NTC thermistor. The protective sleeve 50 primarily serves as a protective element. The mounting base 60 primarily serves as a mounting element.
[0080] The temperature sensing element 40 is placed within the protective sleeve 50, which protects the temperature sensing element 40 and prevents direct impact from the medium, thereby enabling the temperature sensing element 40 to function better. The temperature sensing element 40 is connected to the side of the mounting base 60 adjacent to the protective sleeve 50, which secures the temperature sensing element 40 and makes it more secure and stable, thereby enabling the temperature sensing element 40 to function better. This also facilitates the installation and mating of the temperature sensing element 40 and the protective sleeve 50, further facilitating the protective sleeve 50's protection of the temperature sensing element 40.
[0081] It should be noted that since the temperature sensing component 40 is installed on the mounting base 60, the mounting base 60 is matched with the protective cover 50. This arrangement is more reasonable. While achieving the installation and matching of the mounting base 60 and the protective cover 50, it also facilitates the matching of the temperature sensing component 40 and the protective cover 50.
[0082] In addition, as shown in Figures 2 to 5, 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 provided on the shell 70, and a second limiting portion 51 is provided on the protective cover 50. The first limiting portion and the second limiting portion 51 can both play a limiting role. A third limiting portion 61 is provided on the mounting base 60. 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 setting of the support component 20 more secure and stable, thereby better supporting the pressure sensing component 10 and allowing the pressure sensing component 10 to work better.
[0083] The first limiting portion, the second limiting portion 51, and the third limiting portion 61 can all play a limiting role. The first limiting portion is set on the housing 70, and the second limiting portion 51 is set on the protective sleeve 50. In this way, when the protective sleeve 50 is installed with the housing 70, the cooperation of the first limiting portion and the second limiting portion 51 can make the installation more accurate, and can prevent the protective sleeve 50 from rotating relative to the housing 70, so that the sensor 1 can work better. Similarly, the third limiting portion 61 is set on the mounting base 60, and the first limiting portion is set on the housing 70. In this way, when the mounting base 60 is installed with the housing 70, the cooperation of the first limiting portion and the third limiting portion 61 can make the installation more accurate, and can prevent the mounting base 60 from rotating relative to the housing 70, so that the sensor 1 can work better.
[0084] In addition, as shown in Figure 5, in the axial direction of the sensor 1, 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, aligning the second limiting portion 51 with the third limiting portion 61 can facilitate the second limiting portion 51 and the third limiting portion 61 to match with the first limiting portion at the same time. Moreover, after the second limiting portion 51 and the third limiting portion 61 match with the first limiting portion, the position between the protective cover 50 and the mounting base 60 can also be kept relatively stable, thereby keeping the temperature sensing component relatively stable and allowing the sensor 1 to work better.
[0085] Furthermore, as shown in FIG3 , a step portion 71 is provided in the housing 70, and the protective sleeve 50 is also provided with a mating surface 52. In the first axial direction, the mating 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 against the pressure sensing member 10. The second axial direction is opposite to the first axial direction. The step portion 71 and the mating surface 52 can both play a role in limiting. The step portion 71 is provided in the housing 70, and the mating surface 52 is provided on the protective sleeve 50. In this way, when the protective sleeve 50 is installed on the housing 70, the step portion 71 and the mating surface 52 can be used to limit the protective sleeve 50 in the axial direction, thereby making the installation of the protective sleeve 50 more accurate, improving the assembly efficiency, and making the setting of the protective sleeve 50 more stable.
[0086] The protective member 62 primarily serves a protective function. The protective member 62 is disposed at an end of the mounting base 60 away from the protective sleeve 50 . In this manner, the protective member 62 can abut against the pressure sensing element 10 in the second axial direction. This eliminates the gap between the pressure sensing element 10 and the mounting base 60 , thereby preventing collisions between the pressure sensing element 10 and the mounting base 60 that could affect the normal operation of the sensor 1 .
[0087] It should be noted that the second axial direction is opposite to the first axial direction. Specifically, the first axial direction is the direction from the pressure sensing component 10 to the protective sleeve 50 , and the second axial direction is the direction from the protective sleeve 50 to the pressure sensing component 10 .
[0088] Specifically, as shown in Figures 5 and 7, 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 in turn, wherein the pressure chip 11 mainly processes the pressure information of the medium contacted by the pressure sensing component 10. Setting the pressure chip 11 on the side of the pressure sensing component 10 facing the mounting base 60 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.
[0089] In addition, as shown in Figures 2 and 3, 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 arranged 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, and the sealing member 80 is spaced apart from the mounting base 60 so that 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 arranged 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.
[0090] In addition, as shown in Figures 3 and 8, the support member 20 is provided with a third positioning portion 24, and the housing 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 housing 70. In this way, when the support member 20 is matched with the housing 70, the cooperation between 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 housing 70, thereby making the installation between the support member 20 and the housing 70 more accurate and quick, thereby improving the assembly efficiency.
[0091] 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: the interior of the seal 80 is the medium contact area, and the exterior of the seal 80 is the medium isolation area. Furthermore, the third limiting portion 61, while limiting, also serves as a pressure inlet, allowing the medium to enter the medium contact area through the third limiting portion 61 and then undergo contact sensing with the pressure sensing element 10. Specifically, when the sensor 1 measures the pressure of the medium, the medium can sequentially enter the medium contact area along the second limiting portion 51 and the third limiting portion 61, undergoing contact sensing with the pressure sensing element 10. After sensing the pressure of the medium, the pressure sensing element 10 transmits a corresponding signal to the connector 90, which then outputs the signal to the exterior of the sensor 1.
[0092] Similarly, when sensor 1 measures the temperature of a medium, the medium can enter the interior of protective sleeve 50 through the slotted opening and come into contact with temperature sensing element 40. Temperature sensing element 40 then transmits the sensed medium temperature signal to pressure sensing element 10 via mounting base 60. Pressure sensing element 10 is provided with an electrical connection hole. The medium temperature signal can be transmitted along the bottom of pressure sensing element 10 and then through the electrical connection hole to connector 90, and then output to the exterior of sensor 1. The electrical connection hole is located in the medium isolation area, which prevents leakage of the medium through the electrical connection hole and damage to components within sensor 1.
[0093] As an optional embodiment, the number of electrical connection holes can be greater than or equal to four, and the aperture of the electrical connection hole can be one-fifth of the thickness of the pressure sensing component 10. In addition, the distance between the electrical connection hole and the edge of the pressure sensing component 10 is greater than the aperture of the electrical connection hole.
[0094] As an optional embodiment, the pressure sensing element 10 is a ceramic component. That is, the circuit board in the pressure sensing element 10 can be a ceramic circuit board. Compared to flexible circuit boards, ceramic circuit boards can better prevent damage to the circuit board during the installation of the sensor 1. Furthermore, when the pressure sensing element 10 presses against the sealing element 80, the ceramic material can better compress the sealing element 80, thereby ensuring the sealing of the sensor 1.
[0095] As an optional embodiment, the housing 70 and the connector 90 can be fixed by riveting, which can ensure the sealing of the seal 80. At the same time, RTV glue can be applied around the riveting position to prevent external water vapor from entering the sensor 1 and damaging the pressure sensing element 10.
[0096] It should be noted that the connector 90, pressure sensor 10, and support 20 form a detection unit, which protects the pressure sensor 10 from collision with the housing 70. It also effectively ensures the connection between the pressure sensor 10 and the connector 90, ensuring proper communication. The temperature sensor 40, protective sleeve 50, and mounting base 60 form a temperature sensing unit. Sequentially placing the temperature sensing unit and detection unit within the housing 70 reduces installation steps and improves production efficiency.
