[0035] 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.
[0036] Reference below Figure 1-Figure 9 A sensor 1 according to an embodiment of the present invention is described. The sensor 1 in the present application may be a temperature and pressure sensor 1, which can measure the pressure and temperature of a corresponding medium.
[0037] like Figure 2 and Figure 3As shown, the sensor 1 according to the embodiment of the utility model comprises: a housing 10, a mounting base 20, a support member 30 and a sealing member 50. The housing 10 mainly plays the role of installation and matching. The mounting base 20 mainly plays the role of installation. The support member 30 mainly plays the role of support and installation. The sealing member 50 mainly plays the role of sealing.
[0038] like Figure 2 and Figure 3 As shown, the mounting base 20 is arranged in the shell 10. This arrangement is more reasonable and can fix the mounting base 20, making the arrangement of the mounting base 20 more secure and stable. The mounting base 20 can work better, and the shell 10 can also be used to protect the mounting base 20 to prevent the mounting base 20 from interfering with the external environment.
[0039] like Figure 2 and Figure 3 As shown, the support member 30 is arranged in the shell 10, and a matching groove 40 is defined between the shell 10, the mounting base 20 and the support member 30. The support member 30 is arranged inside the shell 10, so that the support member 30 can be fixed, and the setting of the support member 30 is more reliable and stable, so that the support member 30 can work better, and the shell 10 can also be used to protect the support member 30 to avoid interference between the support member 30 and the external environment. The matching groove 40 mainly plays the role of providing installation space and limiting. The matching groove 40 is defined between the shell 10, the mounting base 20 and the support member 30, that is, between the shell 10, the mounting base 20 and the support member 30, installation space can be provided for corresponding components.
[0040] like Figure 3 As shown, the seal 50 is arranged in the matching groove 40. That is to say, the seal 50 is arranged in the matching groove 40 formed by the housing 10, the mounting base 20 and the support member 30, which is convenient for the installation of the seal 50, and the matching groove 40 can limit the seal 50 to avoid a large displacement of the seal 50, resulting in reduced sealing. It should be noted that after the pressure sensing element 90 is pressed, the pressure sensing element 90 can press the seal 50 located in the matching groove 40 against the housing 10, so that the seal 50 can seal the gap between the pressure sensing element 90 and the housing 10, so that the seal 50 can separate the gap between the pressure sensing element 90 and the housing 10 into two parts, that is, the inside of the seal 50 is the medium contact area, and the outside of the seal 50 is the medium isolation area. The medium can contact and sense the pressure sensing element 90 in the medium contact area, and the seal 50 can prevent the medium from flowing out of the medium contact area, causing damage to the corresponding electronic components in the sensor 1, and affecting the normal operation of the sensor 1.
[0041] Therefore, by setting the seal 50 in the matching groove 40 formed by the shell 10, the mounting base 20 and the support member 30, the installation of the seal 50 is facilitated, and the seal 50 can be limited to avoid the seal 50 from being degraded due to a large displacement. Moreover, the matching groove 40 is formed by the shell 10, the mounting base 20 and the support member 30, so there is no need to open a separate matching groove on the shell, thereby reducing the processing difficulty and reducing costs.
[0042] In some embodiments of the present invention, Figure 3 As shown, the housing 10 is provided with a placement surface 60, the sealing member 50 is provided on the placement surface 60, the mounting base 20 is located on the inner side of the placement surface 60, the mounting base 20 is provided with a protrusion 21, the protrusion 21 protrudes from the placement surface 60, and the support member 30 is located on the outer side of the placement surface 60 to form a matching groove 40. Among them, the placement surface 60 mainly plays the role of installation and placement. The placement surface 60 is provided on the housing 10, and the mounting base 20 and the support member 30 limit the sealing member 50 inside and outside the placement surface 60 respectively, so as to facilitate the formation of the matching groove 40.
[0043] In some embodiments of the present invention, the mounting base 20 is located on the inner side of the placement surface 60, and the mounting base 20 is provided with a protrusion 21, the protrusion 21 is provided protruding from the placement surface 60, and the support member 30 is arranged opposite to the protrusion 21. It should be noted that, since the sealing member 50 is installed in the matching groove 40 formed by the housing 10, the mounting base 20 and the support member 30, specifically, since the protrusion 21 is located on the inner side of the placement surface 60, and the protrusion 21 is protruding from the placement surface 60, the protrusion 21 can form the inner wall surface of the matching groove 40. Similarly, the support member 30 is arranged on the outer side of the placement surface 60, and the support member 30 is arranged opposite to the protrusion 21, that is, the part of the support member 30 opposite to the protrusion 21 is also protruding from the placement surface 60, so the support member 30 can form the outer wall surface of the matching groove 40. In this way, the matching groove 40 can be formed between the placement surface 60 of the housing 10, the support member 30 and the protrusion 21 of the mounting base 20. It can be understood that the portion of the support member 30 that is opposite to the protrusion 21 and the protrusion 21 can respectively limit the two sides of the sealing member 50, thereby preventing the sealing member 50 from undergoing a large displacement, which would lead to a decrease in sealing performance.
[0044] In some embodiments of the present invention, Figure 3 As shown, the seal 50 is spaced apart from the protrusion 21. That is, there is a gap between the seal 50 and the protrusion 21, that is, the seal 50 and the protrusion 21 are clearance-matched, so that the seal 50 is conveniently sleeved on the outer periphery of the protrusion 21, thereby facilitating the installation of the seal 50 and improving the assembly speed of the seal 50.
[0045] like Figure 3 As shown, the inner wall surface of the support member 30 forms a limiting surface 31 to limit the seal 50 on the outside of the seal 50. The limiting surface 31 mainly plays a limiting role. Since the support member 30 is located on the outside of the seal 50, the limiting surface 31 can limit the seal 50 from the outside of the seal 50, thereby preventing the seal 50 from a large displacement and deformation outward, making the setting of the seal 50 more reliable and stable, and the seal 50 can better play a sealing role.
[0046] In some embodiments of the present invention, Figure 3 As shown, the housing 10 is provided with a first pressure stop surface 11, and the support member 30 is provided with a second pressure stop surface 32. When the seal 50 is compressed to a preset value, the first pressure stop surface 11 contacts and cooperates with the second pressure stop surface 32. Among them, the first pressure stop surface 11 and the second pressure stop surface 32 can both play a role of limiting. It should be noted that when the pressure sensing component 90 is press-fitted, the pressure sensing component 90 will press the seal 50 against the housing 10. Since the pressure sensing component 90 is fixed on the support member 30, when the pressure sensing component 90 is press-fitted, the support member 30 will also move accordingly. When the pressure sensing component 90 compresses the seal 50 to a preset value, the first pressure stop surface 11 contacts and cooperates with the second pressure stop surface 32, so that the housing 10 can limit the movement of the support member 30, and then limit the movement of the pressure sensing component 90, so as to avoid the pressure sensing component 90 from causing excessive extrusion to the seal 50 and causing damage to the seal 50, and the seal 50 can perform the sealing work better.
[0047] In addition, if Figure 3 and Fig. 9 As shown, the sensor 1 also includes a pressure sensing member 90 for detecting the pressure of the medium. The pressure sensing member 90 has a first surface 91 and a second surface 92 opposite to each other. The sealing member 50 cooperates with the first surface 91 to separate the first surface 91 into a medium isolation area 93 and a medium contact area 94. In addition, the medium isolation area 93 is provided with at least one electrical connection hole 96, and the electrical connection hole 96 can electrically connect the first surface 91 and the second surface 92. The pressure sensing member 90 has a pressure sensing unit 95 for detecting pressure, and the pressure sensing unit 95 is arranged in the medium contact area 94. Among them, the pressure sensing member 90 mainly plays the role of measuring the pressure of the medium. The sealing member 50 mainly plays the role of sealing and isolation.
[0048] The pressure sensing element 90 is disposed in the medium contact area 94. The medium whose pressure is to be measured contacts the medium contact area 94 in the medium contact area 94. The pressure sensing element 90 disposed in the medium contact area 94 can detect the pressure of the medium. The first surface 91 and the second surface 92 are electrically connected through the electrical connection hole 96. The pressure sensing element 90 is electrically connected to the electrical connection hole 96 through the circuit engraved on the first surface 91.
[0049] By using the sealing member 50 to disconnect the medium contact area 94 from the medium isolation area 93, the medium in the medium contact area 94 can be effectively prevented from flowing to the medium isolation area 93, and the medium can be prevented from leaking from the electrical connection hole 96 located in the medium isolation area 93, thereby increasing the safety and service life of the pressure sensing element 90 and making the detected pressure data more accurate.
[0050] In addition, the aperture of the electrical connection hole 96 is D, and the thickness of the pressure sensing component is H, and D and H satisfy: 1 / 6H≤D≤1 / 3H. If D<1 / 6H, the smaller aperture of the electrical connection hole 96 is not conducive to the arrangement of the electrical connection hole 96 and the stability of the electrical connection between the first surface 91 and the second surface 92; if D>1 / 3H, the larger aperture of the electrical connection hole 96 occupies a larger area of the pressure sensing component 90, which reduces the reliability of the pressure sensing component 90 and is not conducive to the arrangement of components on the pressure sensing component 90. For example, D=1 / 5H. Thus, the range of the aperture of the electrical connection hole 96 relative to the thickness of the pressure sensing component 90 is limited, so that the pressure sensing component 90 has good reliability while facilitating the arrangement of components on the pressure sensing component 90 and the stability of the electrical connection between the first surface 91 and the second surface 92.
[0051] In some examples of the present invention, the aperture of the electrical connection hole 96 is D, and the minimum distance between the electrical connection hole 96 and the edge of the pressure sensing component is L, and D and L satisfy: D≤L≤2D. If L<D, the distance between the electrical connection hole 96 and the edge of the pressure sensing component 90 is small, the structural stability of the pressure sensing component 90 is poor, and the structure of the electrical connection hole 96 is relatively weak, and the stability of the electrical connection of the two side surfaces in the thickness direction of the pressure sensing component 90 is poor; if L>2D, the distance between the electrical connection hole 96 and the edge of the pressure sensing component 90 is large, and the electrical connection hole 96 will be too close to the middle position of the pressure sensing component 90, which is not conducive to the arrangement of components on the pressure sensing component 90. For example, L=1.5D. Therefore, the minimum distance between the electrical connection hole 96 and the edge of the pressure sensing component 90 is limited so that the electrical connection hole 96 and the edge of the pressure sensing component 90 maintain an appropriate distance, which ensures the structural strength of the pressure sensing component 90 and is conducive to the arrangement of components on both sides of the pressure sensing component 90.
[0052] Optionally, the number of the electrical connection holes 96 is N, and N satisfies: N ≥ 4. It should be noted that the number of the electrical connection holes 96 cannot be too small, that is, no less than 4, so that all components on the circuit board can be electrically connected through the electrical connection holes 96, thereby ensuring the normal use of the pressure sensing element 90.
[0053] In addition, if Figure 1-Figure 5 As shown, the sensor 1 further includes: a temperature sensing member 70 and a protective sleeve 80. The temperature sensing member 70 is connected to a side of the mounting base 20 adjacent to the protective sleeve 80, and the temperature sensing member 70 is arranged in the protective sleeve 80. The mounting base 20 is matched with the protective sleeve 80. The temperature sensing member 70 mainly senses and measures the temperature. The protective sleeve 80 mainly plays a protective role. The temperature sensing member 70 can be an NTC thermistor.
[0054] The temperature sensing element 70 is connected to the side of the mounting base 20 adjacent to the protective sleeve 80, so that the temperature sensing element 70 can be fixed, making the setting of the temperature sensing element 70 more reliable and stable, so that the temperature sensing element 70 can work better. It is also convenient for the temperature sensing element 70 to be installed and matched with the protective sleeve 80, so that the protective sleeve 80 can protect the temperature sensing element 70. The temperature sensing element 70 is set in the protective sleeve 80, so that the protective sleeve 80 can be used to protect the temperature sensing element 70, avoiding the medium from directly impacting the temperature sensing element 70, thereby protecting the temperature sensing element 70, and the temperature sensing element 70 can work better. Since the temperature sensing element 70 is installed on the mounting base 20, the mounting base 20 is matched with the protective sleeve 80, so that the setting is more reasonable, and while realizing the installation and matching of the mounting base 20 and the protective sleeve 80, it is convenient for the temperature sensing element 70 to match with the protective sleeve 80.
[0055] In addition, if Figure 5As shown, a first limiting portion is provided on the housing 10, a second limiting portion 81 is provided on the protective sleeve 80, and a third limiting portion 22 is provided on the mounting base 20, and the second limiting portion 81 and the third limiting portion 22 are respectively matched with the first limiting portion. Among them, the first limiting portion, the second limiting portion 81 and the third limiting portion 22 can all play a limiting role. The first limiting portion is provided on the housing 10, and the second limiting portion 81 is provided on the protective sleeve 80, so that the first limiting portion can cooperate with the second limiting portion 81, so that the housing 10 can be used to limit the protective sleeve 80, to avoid the protective sleeve 80 from rotating greatly relative to the housing 10, so that the setting of the protective sleeve 80 is more stable. Similarly, the third limiting portion 22 is provided on the mounting base 20, so that the third limiting portion 22 can also be matched with the first limiting portion, so that the housing 10 can be used to limit the mounting base 20, to avoid the mounting base 20 from rotating greatly relative to the housing 10, so that the setting of the mounting base 20 is more stable.
[0056] One step further, Figure 5 As shown, in the axial direction, the second limiting portion 81 is aligned with the third limiting portion 22. As can be seen from the above, the second limiting portion 81 and the third limiting portion 22 are both matched with the first limiting portion. Therefore, the second limiting portion 81 is aligned with the third limiting portion 22, so that the second limiting portion 81 and the third limiting portion 22 can be easily matched with the first limiting portion at the same time, and after the second limiting portion 81 and the third limiting portion 22 are matched with the first limiting portion at the same time, the position between the protective sleeve 80 and the mounting base 20 can also be kept relatively stable. It should be noted that the cooperation between the second limiting portion 81 and the third limiting portion 22 and the first limiting portion is mainly to limit the circumferential rotation of the protective sleeve 80 and the mounting base 20. The second limiting portion 81 and the third limiting portion 22 can be limiting grooves, and the first limiting portion can be a limiting block.
[0057] In addition, if Figure 3 As shown, a step portion 12 is provided in the housing 10, and a matching surface 82 is also provided in the protective sleeve 80. In the first axial direction, the matching surface 82 is limitedly matched with the surface of the step portion 12. Among them, both the step portion 12 and the matching surface 82 can play a role of limiting. The step portion 12 is provided in the housing 10, and the matching surface 82 is provided on the protective sleeve 80. In this way, when the protective sleeve 80 is installed on the housing 10, the protective sleeve 80 can be limited in the axial direction by using the matching of the step portion 12 and the matching surface 82, so that the installation of the protective sleeve 80 can be more accurate, the assembly efficiency is improved, and the setting of the protective sleeve 80 can also be made more stable.
[0058] In addition, if Figure 2 and Figure 3As shown, the sensor 1 also includes a pressure sensing component 90, which is arranged in the housing 10, and a sealing component 50 is sealed between the pressure sensing component 90 and the housing 10. A protective component 83 is arranged at one end of the mounting base 20 away from the protective sleeve 80. In the second axial direction, the protective component 83 abuts against the pressure sensing component 90, and the second axial direction is opposite to the first axial direction. Among them, the pressure sensing component 90 mainly plays the role of sensing and measuring pressure. The pressure sensing component 90 is arranged in the housing 10, so that the housing 10 can be used to protect the pressure sensing component 90, so that the pressure sensing component 90 can work better.
[0059] The protective member 83 mainly plays a protective role. The protective member 83 is set at one end of the mounting base 20 away from the protective sleeve 80, so that in the second axial direction, the protective member 83 can abut against the pressure sensing member 90, so that the protective member 83 can be used to eliminate the gap between the pressure sensing member 90 and the mounting base 20, thereby avoiding the collision between the pressure sensing member 90 and the mounting base 20, 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 90 toward the protective sleeve 80, and the second axial direction is the direction of the protective sleeve 80 toward the pressure sensing member 90.
[0060] Furthermore, if Figure 3 , Figure 7 and Figure 8 As shown, the support member 30 is provided with a first positioning portion 33 and an abutting portion 34, and the housing 10 is provided with a second positioning portion. The first positioning portion 33 is positioned and matched with the second positioning portion, and the abutting portion 34 is abutted and matched with the outer wall surface of the pressure sensing member 90. Among them, the first positioning portion 33 and the second positioning portion can both play a positioning role. The first positioning portion 33 is provided on the support member 30, and the second positioning portion is provided on the housing 10. In this way, when the support member 30 is matched with the housing 10, the first positioning portion 33 and the second positioning portion can be used to calibrate the position between the support member 30 and the housing 10, so that the installation between the support member 30 and the housing 10 can be made more accurate and fast, thereby improving the assembly efficiency. The abutment portion 34 can play an abutting role. The abutment portion 34 is arranged on the support member 30, so that when the pressure sensing component 90 is connected to the support member 30, the abutment portion 34 can abut against the outer wall surface of the pressure sensing component 90, thereby making the connection between the pressure sensing component 90 and the support member 30 more secure and stable, and the pressure sensing component 90 can work better.
[0061] In addition, if Figure 3 and Figure 6As shown, the sensor 1 further includes a connecting member 100, which abuts against the side of the pressure sensing member 90 away from the mounting base 20. The connecting member 100 mainly serves the function of connection and installation. The connecting member 100 abuts against the side of the pressure sensing member 90 away from the mounting base 20, that is, the connecting member 100 and the supporting member 30 are respectively located on both sides of the pressure sensing member 90. The connecting member 100 abuts against the side of the pressure sensing member 90 away from the mounting base 20, which can further improve the stability of the pressure sensing member 90.
[0062] It should be noted that the seal 50 can separate the gap between the pressure sensing component 90 and the housing 10 into two regions, namely, the inside of the seal 50 is the medium contact region 94, and the outside of the seal 50 is the medium isolation region 93, and the third limiting portion 22 is also a pressure inlet while limiting, and the medium can enter the medium contact region 94 from the third limiting portion 22, and then can perform contact sensing with the pressure sensing component 90. Specifically, when the sensor 1 measures the pressure of the medium, the medium can successively enter the medium contact region 94 along the second limiting portion 81 and the third limiting portion 22 to perform contact sensing with the pressure sensing component 90, and the pressure sensing component 90 will transmit the corresponding signal to the connector 100 after sensing, and then output the signal to the outside of the sensor 1.
[0063] Similarly, when the sensor 1 measures the temperature of the medium, a notch is provided on the side of the protective cover 80 away from the mounting base 20, and the medium can enter the protective cover 80 through the notch to contact the temperature sensing component 70. The temperature sensing component 70 transmits the sensed medium temperature signal to the pressure sensing component 90 through the mounting base 20. The pressure sensing component 90 is provided with an electrical connection hole 96. The medium temperature signal can be successively transmitted to the connector 100 along the bottom of the pressure sensing component 90 and the electrical connection hole 96, and then the signal is output to the outside of the sensor 1. The electrical connection hole 96 is located in the medium isolation area, so that the medium can be prevented from leaking through the electrical connection hole 96 and causing damage to the internal components of the sensor 1.
[0064] In addition, if Figure 2 , Figure 3 and Figure 6As shown, the connector 100 is provided with a third positioning portion 101 and a first plug-in portion 102, and the support member 30 is also provided with a fourth positioning portion 35 and a second plug-in portion 36. The third positioning portion 101 is positioned and matched with the fourth positioning portion 35, and the first plug-in portion 102 is plug-matched with the second plug-in portion 36. Among them, the third positioning portion 101 and the fourth positioning portion 35 can both play a positioning role. The third positioning portion 101 is arranged on the connector 100, and the fourth positioning portion 35 is arranged on the support member 30. In this way, when the connector 100 is installed and matched with the support member 30, the third positioning portion 101 and the fourth positioning portion 35 can be used to calibrate the position between the connector 100 and the support member 30, so that the installation between the connector 100 and the support member 30 can be more accurate and fast, thereby improving the assembly efficiency.
[0065] The first plug-in portion 102 and the second plug-in portion 36 can both play a plug-in role. The first plug-in portion 102 is arranged on the connector 100, and the second plug-in portion 36 is arranged on the support member 30. In this way, when the connector 100 and the support member 30 are installed and matched, the first plug-in portion 102 can be plugged and matched with the second plug-in portion 36, so that the connection between the connector 100 and the support member 30 can be more stable. It should be noted that after the connector 100 and the support member 30 are installed, they can wrap the pressure sensing member 90 located in the middle to a certain extent, so as to avoid contact between the pressure sensing member 90 and the housing 10, thereby avoiding damage to the pressure sensing member 90 during the press-fitting process, and ensuring the effective connection between the connector 100 and the pressure sensing member 90.
[0066] As an optional embodiment, the pressure sensing element 90 is a ceramic element. That is, the circuit board in the pressure sensing element 90 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 90 presses the sealing element 50, the ceramic material can better press the sealing element 50, thereby ensuring the sealing of the sensor 1.
[0067] As an optional embodiment, the housing 10 and the connector 100 may be fixed by riveting, which can ensure the sealing of the seal 50. 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 90.
[0068] It should be noted that the connector 100, the pressure sensing component 90 and the support component 30 can form a detection unit, which can protect the pressure sensing component 90, prevent the pressure sensing component 90 from colliding with the housing 10, and effectively ensure the connection between the pressure sensing component 90 and the connector 100 to ensure that their communication function is normal. The temperature sensing component 70, the protective cover 80, and the mounting base 20 can form a temperature sensing unit. The temperature sensing unit and the detection unit are sequentially placed inside the housing 10, which can reduce the installation steps of the process and improve production efficiency.
