[0041] 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.

[0042] Reference below Figure 1-Figure 10 The sensor 1 according to the 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 the corresponding medium.

[0043] like Figure 2 As shown, the sensor 1 according to the embodiment of the utility model comprises: a temperature sensing component 10, a housing 20 and a pressure sensing component 30. The temperature sensing component 10 is mainly used to sense the temperature of the medium, and the housing 20 is mainly used for installation and matching. The pressure sensing component 30 is mainly used to sense and measure pressure.

[0044] like Figure 2 , Figure 3 , Figure 5 and Fig.10 As shown, the temperature sensing component 10 includes: a mounting seat 12, and the mounting seat 12 is provided with a pressure inlet hole 121. Among them, the mounting seat 12 mainly plays a role of installation. The pressure inlet hole 121 is set on the mounting seat 12, so that the external medium can contact the pressure sensing element 30 through the pressure inlet hole 121, so that the pressure sensing element 30 can sense the pressure of the medium.

[0045] The housing 20 is provided with a first limiting portion 22, and the first limiting portion 22 is limitedly matched with the pressure inlet hole 121. The first limiting portion 22 mainly plays a limiting role, the pressure inlet hole 121 is provided on the mounting seat 12, and the first limiting portion 22 is provided on the housing 20, so that when the mounting seat 12 and the housing 20 are installed, the pressure inlet hole 121 and the first limiting portion 22 cooperate to install more accurately, and the mounting seat 12 can be prevented from rotating relative to the housing 20, so that the sensor 1 can work better.

[0046] like Figure 2 and Figure 3 As shown, the pressure sensing element 30 is arranged in the housing 20, and the medium can contact the pressure sensing element 30 through the pressure inlet hole 121. The pressure sensing element 30 is arranged in the housing 20, so that the housing 20 can be used to protect the pressure sensing element 30, so that the pressure sensing element 30 can work better. It should be noted that the external medium can enter through the pressure inlet hole 121 and then contact the pressure sensing element 30, so that the pressure sensing element 30 can measure the pressure of the medium.

[0047] Therefore, by setting the pressure inlet hole 121 on the mounting seat 12, and the pressure inlet hole 121 is limited and matched with the first limit part 22 on the shell 20, the mounting seat 12 can be installed accurately while avoiding the mounting seat 12 from rotating relative to the shell 20, thereby ensuring the stability of the sensor 1, so that the sensor 1 can work better, and the setting of the pressure inlet hole 121 can facilitate the medium to enter the mounting seat through the pressure inlet hole 121, thereby facilitating the pressure sensing element 30 to measure the pressure of the medium. In this way, the pressure inlet hole 121 can simultaneously play the role of pressure inlet and limit with the shell 20, thereby simplifying the structure of the mounting seat 12, reducing the difficulty of processing the mounting seat 12, and thus reducing the manufacturing cost of the sensor.

[0048] In addition, if Fig. 9 As shown, a pressure chip 31 is provided on the side of the pressure sensing component 30 facing the mounting seat 12, and the medium can contact the pressure chip 31 through the pressure inlet hole 121. The pressure chip 31 is the main part of the pressure sensing component 30, and can sense the pressure of the medium. The medium can contact the pressure chip 31 of the pressure sensing component 30 through the pressure inlet hole 121, so that the pressure chip 31 can sense the pressure of the medium.

[0049] In addition, if Figure 2 , Figure 3 and Figure 5 As shown, the temperature sensing component 10 includes: a protective sleeve 11, a mounting seat 12 matched with the protective sleeve 11, the protective sleeve 11 is provided with a second limiting portion 111, and the first limiting portion 22 is also limited and matched with the second limiting portion 111. Among them, the protective sleeve 11 mainly plays a protective role. The mounting seat 12 is matched with the protective sleeve 11. It should be noted that since the temperature sensing component 13 is installed on the mounting seat 12, the mounting seat 12 is matched with the protective sleeve 11. This arrangement is more reasonable. While realizing the installation and matching of the mounting seat 12 and the protective sleeve 11, it is convenient for the temperature sensing component 13 to match with the protective sleeve 11.

[0050] The second limiting portion 111 mainly plays a limiting role. The second limiting portion 111 is arranged on the protective sleeve 11, and the first limiting portion 22 is arranged on the housing 20. In this way, when the protective sleeve 11 and the housing 20 are installed, the second limiting portion 111 and the first limiting portion 22 cooperate to install more accurately, and the protective sleeve 11 can be prevented from rotating relative to the housing 20, so that the sensor 1 can work better. Moreover, the first limiting portion 22 can simultaneously cooperate with the second limiting portion 111 on the protective sleeve 11 and the pressure inlet hole 121 on the mounting seat 12, so that the structure of the housing 20 can be simplified and the processing difficulty can be reduced.

[0051] Furthermore, if Figure 2 and Figure 5 As shown, the first limiting portion 22 is configured as a limiting protrusion, the second limiting portion 111 is configured as a limiting groove, the pressure inlet hole 121 is limitedly matched with the limiting protrusion, and the limiting groove is limitedly matched with the limiting protrusion. In other words, the second limiting portion 111 can be a limiting groove, and the first limiting portion 22 can be a convex structure. Through the limiting cooperation between the convex portion, the limiting groove and the pressure inlet hole 121, the protective sleeve 11 and the mounting seat 12 can be prevented from rotating relative to the housing 20. Moreover, the structures of the limiting groove, the pressure inlet hole 121 and the limiting protrusion are simple, which is convenient for processing and setting.

[0052] In addition, if Figure 5 As shown, in the axial direction, the limiting groove is aligned with the pressure inlet hole 121. As can be seen from the above, both the pressure inlet hole 121 and the limiting groove cooperate with the first limiting portion 22. Therefore, the pressure inlet hole 121 is aligned with the limiting groove, which makes it easy for the pressure inlet hole 121 and the limiting groove to cooperate with the first limiting portion 22 at the same time. Moreover, after the pressure inlet hole 121 and the limiting groove cooperate with the first limiting portion 22, the position between the protective cover 11 and the mounting seat 12 can also be kept relatively stable, so that the temperature sensing component 10 can be kept relatively stable, and the sensor 1 can work better.

[0053] Specifically, Figure 3 As shown, a step portion 21 is provided in the housing 20, and a matching surface 112 is also provided in the protective sleeve 11. In the first axial direction, the matching surface 112 is limitedly matched with the surface of the step portion 21. Among them, both the step portion 21 and the matching surface 112 can play a limiting role. The step portion 21 is provided in the housing 20, and the matching surface 112 is provided on the protective sleeve 11. In this way, when the protective sleeve 11 is installed on the housing 20, the protective sleeve 11 can be limited in the axial direction by using the matching of the step portion 21 and the matching surface 112, so that the installation of the protective sleeve 11 can be more accurate, the assembly efficiency is improved, and the setting of the protective sleeve 11 can also be made more stable.

[0054] like Figure 3As shown, in the second axial direction, the end of the mounting seat 12 away from the protective sleeve 11 is in abutment with the pressure sensing component 30, and the second axial direction is opposite to the first axial direction. In this way, in the second axial direction, the end of the mounting seat 12 away from the protective sleeve 11 can be in abutment with the pressure sensing component 30, thereby eliminating the gap between the pressure sensing component 30 and the mounting seat 12, thereby avoiding collision between the pressure sensing component 30 and the mounting seat 12, 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 component 30 toward the protective sleeve 11, and the second axial direction is the direction of the protective sleeve 11 toward the pressure sensing component 30.

[0055] In addition, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a seal 40, which is spaced apart from the mounting seat 12, and the seal 40 is sealingly disposed between the pressure sensing element 30 and the housing 20. The seal 40 mainly plays a sealing role. It should be noted that the seal 40 is sleeved on the mounting seat 12, so the seal 40 is spaced apart from the mounting seat 12, that is, there is a gap between the seal 40 and the mounting seat 12, which facilitates the installation of the seal 40. Moreover, the seal 40 is sealingly disposed between the pressure sensing element 30 and the housing 20, so that the seal 40 can seal the gap between the pressure sensing element 30 and the housing 20.

[0056] In addition, if Figure 2 , Figure 7 , Figure 8 and Fig.10 As shown, the sensor 1 also includes a support member 50, the pressure sensing member 30 is arranged on the support member 50, the support member 50 is provided with a first positioning portion 51 and a matching portion 52, and a second positioning portion 23 is provided on the shell 20, the first positioning portion 51 is positioned and matched with the second positioning portion 23, and the matching portion 52 is suitable for limiting and matching with the side wall surface of the pressure sensing member 30.

[0057] The support member 50 mainly plays the role of support and installation. The pressure sensing member 30 is arranged on the support member 50, so that the pressure sensing member 30 can be fixed, so that the arrangement of the pressure sensing member 30 is more reliable and stable, and the pressure sensing member 30 can work more stably. The first positioning portion 51 and the second positioning portion 23 can both play the role of positioning. The first positioning portion 51 is arranged on the support member 50, and the second positioning portion 23 is arranged on the shell 20. In this way, when the support member 50 is matched with the shell 20, the first positioning portion 51 and the second positioning portion 23 can be used to calibrate the position between the support member 50 and the shell 20, so that the installation between the support member 50 and the shell 20 can be more accurate and fast, thereby improving the assembly efficiency. The mating portion 52 can limit the pressure sensing component 30. The mating portion 52 is arranged on the support component 50. In this way, when the pressure sensing component 30 is connected to the support component 50, the mating portion 52 can limit the side wall surface of the pressure sensing component 30, thereby ensuring the position of the pressure sensing component 30 to improve the stability of electrical connection or signal transmission.

[0058] Furthermore, if Figure 7 and Fig. 9 As shown, the sensor 1 also includes a connecting spring 60, which is connected to the side of the pressure sensing component 30 facing the support component 50, and the support component 50 is provided with a through hole 55, and the connecting spring 60 is penetrated through the through hole to contact with the shell 20. Among them, the connecting spring 60 mainly plays the role of electrical connection. The through hole 55 can play the role of positioning and installation. The connecting spring 60 is penetrated by the through hole 55, so that the through hole 55 has a positioning effect on the connecting spring 60, which can improve the accuracy of the assembly of the pressure sensing component 30, and to a certain extent, it can also protect the connecting spring 60. In addition, it is also convenient for the connecting spring 60 to contact with the shell 20. Therefore, the connecting spring 60 is connected to the side of the pressure sensing component 30 facing the support component 50. Such a setting is more reasonable and convenient for the connecting spring 60 to cooperate with the through hole 55. 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 60 can be electrically connected to the housing 20 through the through hole 55, so that the sensor 1 can be grounded.

[0059] In addition, if Figure 1 , Figure 2 , Figure 3 and Figure 6As shown, the sensor 1 further includes a connector 70, which is connected to the side of the pressure sensing member 30 away from the support member 50. The connector 70 mainly serves the function of connection and installation. The connector 70 is connected to the side of the pressure sensing member 30 away from the mounting seat 12, that is, the connector 70 and the support member 50 are respectively located on both sides of the pressure sensing member 30. The connector 70 is connected to the side of the pressure sensing member 30 away from the support member 50, which can improve the stability of the pressure sensing member 30.

[0060] In addition, if Figure 1 , Figure 2 , Figure 3 and Figure 6 As shown, the connector 70 is provided with a third positioning portion 71 and a first plug-in portion 72, and the support member 50 is also provided with a fourth positioning portion 53 and a second plug-in portion 54. The third positioning portion 71 is positioned and matched with the fourth positioning portion 53, and the first plug-in portion 72 is plugged and matched with the second plug-in portion 54. Among them, the third positioning portion 71 and the fourth positioning portion 53 can both play a positioning role. The third positioning portion 71 is arranged on the connector 70, and the fourth positioning portion 53 is arranged on the support member 50. In this way, when the connector 70 and the support member 50 are installed and matched, the third positioning portion 71 and the fourth positioning portion 53 can be used to calibrate the position between the connector 70 and the support member 50, so that the installation between the connector 70 and the support member 50 can be made more accurate and fast, thereby improving the assembly efficiency.

[0061] Specifically, the first plug-in portion 72 is a buckle, the second plug-in portion 54 is a boss that cooperates with the buckle, the third positioning portion 71 is a positioning column, and the fourth positioning portion is a positioning hole that cooperates with the positioning column. The buckle, boss, positioning column and positioning hole have simple structures and are easy to process and manufacture. Moreover, the connector 70 is provided with a buckle and a positioning column, and the support member 50 is provided with a boss and a positioning hole, so that the transportation cost of the support member 50 can be reduced without almost increasing the transportation cost of the connector 70, thereby reducing the manufacturing cost of the entire sensor.

[0062] It should be noted that the seal 40 can separate the gap between the pressure sensing element 30 and the housing 20 into two areas, that is, the inside of the seal 40 is the medium contact area, and the outside of the seal 40 is the medium isolation area, and the pressure inlet hole 121 is also the pressure inlet port while limiting, and the medium can enter the medium contact area from the pressure inlet hole 121, and then can perform contact sensing with the pressure sensing element 30. Specifically, when the sensor 1 measures the pressure of the medium, the medium can successively enter the medium contact area along the second limiting portion 111 and the pressure inlet hole 121 to perform contact sensing with the pressure sensing element 30, and the pressure sensing element 30 will transmit the corresponding signal to the connector 70 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 at one end of the protective cover 11 away from the mounting seat 12, and the medium can enter the protective cover 11 through the notch to contact the temperature sensing component 13. The temperature sensing component 13 transmits the sensed medium temperature signal to the pressure sensing component 30 through the mounting seat 12. The pressure sensing component 30 is provided with an electrical connection hole, and the medium temperature signal can be successively transmitted to the connector 70 along the bottom of the pressure sensing component 30 and the electrical connection hole, and then the signal is output to the outside of the sensor 1. The electrical connection hole is located in the medium isolation area, so that the medium can be prevented from leaking through the electrical connection hole and causing damage to the internal components of the sensor 1. The pressure chip 31 is located in the medium contact area.

[0064] The first plug-in portion 72 and the second plug-in portion 54 can both play a plug-in role. The first plug-in portion 72 is arranged on the connector 70, and the second plug-in portion 54 is arranged on the support member 50. In this way, when the connector 70 and the support member 50 are installed and matched, the first plug-in portion 72 can be plugged and matched with the second plug-in portion 54, so that the connection between the connector 70 and the support member 50 can be more stable. It should be noted that after the connector 70 and the support member 50 are installed, they can wrap the pressure sensing member 30 located in the middle to a certain extent, so as to avoid contact between the pressure sensing member 30 and the housing 20, thereby avoiding damage to the pressure sensing member 30 during the press-fitting process, and ensuring the effective connection between the connector 70 and the pressure sensing member 30.

[0065] Furthermore, if Figure 2 and Figure 3 As shown, the temperature sensing component 10 also includes a protective cover 11 and a temperature sensing element 13, wherein the temperature sensing element 13 is connected to the mounting base 12, and the protective cover 11 is arranged outside the temperature sensing element 13. The temperature sensing element 13 mainly senses and measures the temperature. The temperature sensing element 13 can be an NTC thermistor. The protective cover 11 is arranged outside the temperature sensing element 13, so that the protective cover 11 can be used to protect the temperature sensing element 13, and avoid the medium directly impacting the temperature sensing element 13, so that the temperature sensing element 13 can work better.

[0066] The temperature sensing element 13 is connected to the mounting base 12, so that the temperature sensing element 13 can be fixed, and the setting of the temperature sensing element 13 is more reliable and stable, so that the temperature sensing element 13 can work better. It is also convenient for the temperature sensing element 13 to be installed and matched with the protective cover 11, and then it is convenient for the protective cover 11 to protect the temperature sensing element 13.

[0067] As an optional embodiment, the pressure sensing component 30 is a ceramic component. That is, the circuit board in the pressure sensing component 30 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 component 30 presses the sealing component 40, the ceramic material can better press the sealing component 40, thereby ensuring the sealing performance of the sensor 1.

[0068] As an optional embodiment, the housing 20 and the connector 70 may be fixed by riveting, which can ensure the sealing of the seal 40. 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 30.

[0069] It should be noted that the connector 70, the pressure sensing element 30 and the support element 50 can form a detection part, which can protect the pressure sensing element, prevent the pressure sensing element 30 from colliding with the housing 20, and effectively ensure the connection between the pressure sensing element 30 and the connector 70 to ensure that its communication function is normal. The temperature sensing element 13, the protective cover 11, and the mounting seat 12 can form a temperature sensing part. The temperature sensing part and the detection part are placed in the housing 20 in sequence, which can reduce the installation steps of the process and improve production efficiency.
