[0042] 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.

[0043] Reference below Figure 1-Figure 10 A pressure sensing component according to an embodiment of the utility model is described. The pressure sensing component is mainly used to sense and measure the pressure of a medium.

[0044] like Figure 2 and Figure 3 As shown, the pressure sensing assembly according to the embodiment of the utility model comprises: a support member 20 and a connector 30. The support member 20 mainly plays the role of installation and support. The connector 30 mainly plays the role of electrical connection and signal transmission.

[0045] like Figure 3 and Fig. 9As shown, the support member 20 is provided with a first plug-in portion 21, and the first plug-in portion 21 has a first plug-in surface 210. The first plug-in portion 21 mainly plays a role of plug-in matching. The first plug-in portion 21 is arranged on the support member 20, so that the support member 20 can use the first plug-in portion 21 to perform plug-in matching with a corresponding component, and the first plug-in surface 210 is the contact surface of the first plug-in portion 21 and the corresponding component for plug-in matching.

[0046] like Figure 2 , Figure 6 and Fig. 9 As shown, the connector 30 is provided with a second plug-in portion 31, and the second plug-in portion 31 has a second plug-in surface 310. The first plug-in surface 210 and the second plug-in surface 310 can abut against each other so that the second plug-in portion 31 and the first plug-in portion 21 can be plugged and matched. Among them, the second plug-in portion 31 mainly plays the role of plug-in matching. The second plug-in portion 31 is arranged on the connector 30, so that the connector 30 can use the second plug-in portion 31 to plug and match with the corresponding component, and the second plug-in surface 310 is the contact surface for the second plug-in portion 31 to plug and match with the corresponding component. Specifically, the first plug-in surface 210 and the second plug-in surface 310 can be limited by abutting against each other, so that the support 20 and the connector 30 can be plugged and matched. In this way, the support 20 and the connector 30 can be pre-installed first to facilitate the assembly of the sensor.

[0047] like Fig. 9 As shown, after the sensor 1 is assembled, the first plugging surface 210 and the second plugging surface 310 are clearance-matched in the plugging direction. That is to say, when the first plugging surface 210 and the second plugging surface 310 are plugged and matched, there is space between the first plugging surface 210 and the second plugging surface 310 for movement along the plugging direction. During the formal press-fitting process of the pressure sensing component and the housing, the first plugging surface 210 and the second plugging surface 310 move relative to each other. After the assembly is completed, the first plugging surface 210 and the second plugging surface 310 are clearance-matched. Such an assembly process is conducive to the accurate positioning of various components of the sensor.

[0048] It should be noted that a pressure sensing component 10 is provided on the support member 20, and the signal is transmitted between the pressure sensing component 10 and the connector through the first connecting spring piece 40. Through the plug-in cooperation between the second plug-in portion 31 and the first plug-in portion 21, the connector 30 can first pre-tighten the first connecting spring piece 40 on the pressure sensing component 10, and then perform formal press-fitting. This is conducive to achieving accurate positioning of various components of the sensor, and can improve the stability of the connection between the connector 30 and the support member 20, and can improve the stability of the electrical connection between the connector 30 and the pressure sensing component 10, so that the signal can be transmitted more stably between the connector 30 and the pressure sensing component 10.

[0049] In some embodiments of the present invention, Figure 3 As shown, the pressure sensing component also includes a pressure sensing element 10, which is arranged on the support member 20 and is located between the support member 20 and the connector 30. The pressure sensing element 10 is mainly used to sense pressure and can sense the pressure of the medium. The pressure sensing element 10 is arranged on the support member 20, so that the pressure sensing element 10 can be fixed, making the setting of the pressure sensing element 10 more secure and stable, and the pressure sensing element 10 can work better. Since the pressure sensing element 10 cooperates with the connector 30 through the first connecting spring 40, the pressure sensing element 10 is arranged between the support member 20 and the connector 30. This arrangement is more reasonable and convenient for the pressure sensing element 10 to cooperate with the connector 30.

[0050] In some embodiments of the present invention, the pressure sensing component further includes a first connecting spring 40, which is connected to the side of the pressure sensing component 10 away from the support component 20, the maximum compression dimension of the first connecting spring 40 is b, the distance between the first plug-in surface 210 and the second plug-in surface 310 is d, and the relationship between b and d is: 0<d≤b. The first connecting spring 40 mainly plays the role of electrical connection. The signal on the pressure sensing component 10 can be transmitted to the connector 30 through the first connecting spring 40.

[0051] The first connecting spring 40 is connected to the side of the pressure sensing component 10 away from the support component 20, and the distance between the first plug-in surface 210 and the second plug-in surface 310 is d. The first connecting spring 40 is mainly used for the electrical connection between the pressure sensing component 10 and the connector 30. The signal on the pressure sensing component 10 can be transmitted to the connector 30 through the first connecting spring 40, and then output to the outside of the sensor 1. Therefore, the first connecting spring 40 is connected to the side of the pressure sensing component 10 away from the support component 20. This arrangement is more reasonable, so that the first connecting spring 40 is closer to the pressure sensing component 10, which is convenient for the first connecting spring 40 to be connected to the pressure sensing component 10.

[0052] It should be noted that the first plug-in portion 21 can be a plug-in protrusion, and the second plug-in portion 31 can be a plug-in slot. When the lower surface of the plug-in slot abuts against the lower surface of the plug-in protrusion, the first plug-in portion 21 and the second plug-in portion 31 are plugged together, that is, the lower surface of the plug-in slot is the second plug-in surface 310, and the lower surface of the plug-in protrusion is the first plug-in surface 210; when the pressure sensing component is formally pressed together with the shell as a whole by molding, at this time, the distance between the first plug-in surface 210 and the second plug-in surface 310 is d, and when d satisfies the relationship 0<d≤b, it can ensure that after the formal pressing, the connector 30 and the first connecting spring piece 40 have better contact, thereby ensuring normal electrical connection and signal transmission between the pressure sensing component 10 and the connector 30.

[0053] It should be noted that the first plug-in portion 21 may also be a plug-in groove, and the second plug-in portion 31 may also be a plug-in protrusion.

[0054] In some embodiments of the present invention, 0.5b<d<b, wherein, after formal press-fitting, the spacing d between the first plug-in surface 210 and the second plug-in surface 310 needs to be greater than 0.5b, that is, when the connector 30 performs pre-pressing on the first connecting spring piece 40, the pre-pressing amount of the connector 30 on the first connecting spring piece 40 is less than or equal to 0.5b. In this way, during the formal press-fitting process, the relative movement distance between the connector 30 and the support member 20 can be relatively large, thereby facilitating improving the qualified rate of the product.

[0055] In addition, if Figure 6 and Figure 7 As shown, the connector 30 is provided with a first positioning portion 32, and the support member 20 is provided with a second positioning portion 22, and the first positioning portion 32 is positioned and matched with the second positioning portion 22. Among them, the first positioning portion 32 and the second positioning portion 22 can both play a positioning role. The first positioning portion 32 is provided on the connector 30, and the second positioning portion 22 is provided on the support member 20. In this way, when the connector 30 and the support member 20 are installed, the positioning and matching between the first positioning portion 32 and the second positioning portion 22 can improve the installation accuracy between the connector 30 and the support member 20, thereby improving the assembly efficiency.

[0056] Furthermore, if Figure 6 As shown, there are two first positioning portions 32, and the diameters of the two first positioning portions 32 are different. By setting two first positioning portions 32, the installation of the connector 30 and the support member 20 can be positioned at two positions, thereby further improving the accuracy of the installation. The diameters of the two first positioning portions 32 are different, that is, the two first positioning portions 32 are asymmetrically arranged, so that the installation misalignment of the connector 30 and the support member 20 can be avoided. Of course, the two first positioning portions 32 can also be asymmetrical in shape, size, or position.

[0057] Specifically, Figure 6 As shown, the end face of the connector 30 facing the support member 20 is constructed as a circle, and on the end face, the center of the connector 30 does not pass the line connecting the centers of the two first positioning portions 32. Since the outer shape of the support member 20 is constructed as a circle, the connector 30 is constructed as a circular structure, which is convenient for the connector 30 to match with the support member 20, and the circular structure is simple, easy to process and set. The center of the connector 30 does not pass the line connecting the centers of the two first positioning portions 32, that is, the line connecting the centers of the two first positioning portions 32 is not colinear with the center of the connector 30, that is, the positions of the two first positioning portions 32 are asymmetrical, which can avoid the installation misalignment of the connector 30 and the support member 20.

[0058] In addition, if Fig.10 As shown, the sensor 1 also includes a second connecting spring piece 50, which is connected to the side of the pressure sensing component 10 adjacent to the support component 20, and the support component 20 is provided with a through hole, and the second connecting spring piece 50 is penetrated by the through hole. Among them, the connecting spring piece mainly plays the role of electrical connection. The through hole can play the role of positioning and installation. The connecting spring piece is penetrated by the through hole, so that the through hole has a positioning effect on the connecting spring piece, which can improve the accuracy of the assembly of the pressure sensing component 10, and can also protect the connecting spring piece to a certain extent. Therefore, the connecting spring piece is connected to the side of the pressure sensing component 10 adjacent to the support component 20. This setting is more reasonable and facilitates the matching of the connecting spring piece and the through hole. 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 piece can be electrically connected to the shell 90 through the through hole, so that the grounding of the sensor 1 can be achieved.

[0059] Furthermore, if Figure 8 and Fig. 9 As shown, the support member 20 is provided with a matching portion 24, and the matching portion 24 is limitedly matched with the side wall surface of the pressure sensing member 10. In this way, when the pressure sensing member 10 is installed on the support member 20, the matching portion 24 can limit the side wall surface of the pressure sensing member 10, thereby ensuring the position accuracy of the pressure sensing member 10.

[0060] In some embodiments of the present invention, the pressure sensing element 10 is a ceramic element.

[0061] 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, which can measure the pressure and temperature of the corresponding medium.

[0062] Furthermore, if Figure 2 and Figure 3 As shown, the sensor 1 further includes a temperature sensing element 60, a protective cover 70 and a mounting base 80. The temperature sensing element 60 is connected to a side of the mounting base 80 adjacent to the protective cover 70, and the temperature sensing element 60 is arranged in the protective cover 70, and the mounting base 80 is matched with the protective cover 70. Among them, the temperature sensing element 60 is mainly used to sense the temperature of the medium, and the temperature sensing element 60 can be an NTC thermistor. The protective cover 70 mainly plays a protective role. The mounting base 80 mainly plays a mounting role.

[0063] The temperature sensing element 60 is arranged in the protective sleeve 70, so that the protective sleeve 70 can be used to protect the temperature sensing element 60, and the medium can be prevented from directly impacting the temperature sensing element 60, so that the temperature sensing element 60 can work better. The temperature sensing element 60 is connected to the side of the mounting base 80 adjacent to the protective sleeve 70, so that the temperature sensing element 60 can be fixed, so that the setting of the temperature sensing element 60 is more reliable and stable, so that the temperature sensing element 60 can work better. It is also convenient for the temperature sensing element 60 to be installed and matched with the protective sleeve 70, and then it is convenient for the protective sleeve 70 to protect the temperature sensing element 60.

[0064] It should be noted that, since the temperature sensing element 60 is mounted on the mounting base 80, the mounting base 80 is matched with the protective cover 70. This arrangement is more reasonable, and while the mounting base 80 and the protective cover 70 are installed and matched, it is convenient for the temperature sensing element 60 to match with the protective cover 70. Both the first limiting portion and the second limiting portion 71 can play a limiting role.

[0065] In addition, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a shell 90, the pressure sensing component 10 and the support component 20 are both arranged in the shell 90, a first limiting portion is arranged on the shell 90, a second limiting portion 71 is arranged on the protective cover 70, and a third limiting portion 81 is arranged on the mounting base 80, and the second limiting portion 71 and the third limiting portion 81 are respectively limited and matched with the first limiting portion. Among them, the shell 90 mainly plays the role of installation and matching. The pressure sensing component 10 and the support component 20 are both arranged in the shell 90, 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.

[0066] The first limiting part, the second limiting part 71 and the third limiting part 81 can all play a limiting role. The first limiting part is arranged on the shell 90, and the second limiting part 71 is arranged on the protective cover 70. In this way, when the protective cover 70 and the shell 90 are installed, the first limiting part and the second limiting part 71 cooperate to install more accurately, and the protective cover 70 can be prevented from rotating relative to the shell 90, so that the sensor 1 can work better. Similarly, the third limiting part 81 is arranged on the mounting base 80, and the first limiting part is arranged on the shell 90. In this way, when the mounting base 80 and the shell 90 are installed, the first limiting part and the third limiting part 81 cooperate to install more accurately, and the mounting base 80 can be prevented from rotating relative to the shell 90, so that the sensor 1 can work better.

[0067] In addition, if Figure 3As shown, in the axial direction, the second limiting portion 71 is aligned with the third limiting portion 81. The second limiting portion 71 is aligned with the third limiting portion 81. As can be seen from the above, the second limiting portion 71 and the third limiting portion 81 are both matched with the first limiting portion. Therefore, the second limiting portion 71 is aligned with the third limiting portion 81, which can facilitate the second limiting portion 71 and the third limiting portion 81 to be matched with the first limiting portion at the same time. After the second limiting portion 71 and the third limiting portion 81 are matched with the first limiting portion, the position between the protective cover 70 and the mounting base 80 can also be kept relatively stable, so that the temperature sensing component can be kept relatively stable, and the sensor 1 can work better.

[0068] Furthermore, if Figure 3 As shown, a step portion 91 is provided in the shell 90, and the protective sleeve 70 is also provided with a matching surface 72. In the first axial direction, the matching surface 72 is limitedly matched with the surface of the step portion 91. A protective member 82 is provided at the end of the mounting base 80 away from the protective sleeve 70. In the second axial direction, the protective member 82 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 91 and the matching surface 72 can play a limiting role. The step portion 91 is provided in the shell 90, and the matching surface 72 is provided on the protective sleeve 70. In this way, when the protective sleeve 70 is installed on the shell 90, the step portion 91 and the matching surface 72 can be used to limit the protective sleeve 70 in the axial direction. Therefore, the installation of the protective sleeve 70 can be more accurate, the assembly efficiency is improved, and the setting of the protective sleeve 70 can also be made more stable.

[0069] The protective member 82 mainly plays a protective role. The protective member 82 is set at one end of the mounting base 80 away from the protective sleeve 70, so that in the second axial direction, the protective member 82 can abut against the pressure sensing member 10, so that the protective member 82 can be used to eliminate the gap between the pressure sensing member 10 and the mounting base 80, thereby avoiding a collision between the pressure sensing member 10 and the mounting base 80, 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 70, and the second axial direction is the direction of the protective sleeve 70 toward the pressure sensing member 10.

[0070] In addition, if Figure 2 and Figure 3As shown, the sensor 1 also includes a seal 100, which can be a sealing ring. The seal 100 is spaced apart from the mounting base 80, and the seal 100 is sealingly disposed between the pressure sensing component 10 and the housing 90. Among them, the seal 100 mainly plays a sealing role. It should be noted that the seal 100 is sleeved on the mounting base 80, so the seal 100 is spaced apart from the mounting base 80, that is, there is a gap between the seal 100 and the mounting base 80, which facilitates the installation of the seal 100. Moreover, the seal 100 is sealingly disposed between the pressure sensing component 10 and the housing 90, so that the seal 100 can seal the gap between the pressure sensing component 10 and the housing 90.

[0071] It should be noted that the seal 100 can separate the gap between the pressure sensing element 10 and the housing 90 into two areas, that is, the inside of the seal 100 is the medium contact area, and the outside of the seal 100 is the medium isolation area, and the third limit portion 81 is also a pressure inlet while limiting, and the medium can enter the medium contact area from the third limit portion 81, 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 71 and the third limit portion 81 to perform contact sensing with the pressure sensing element 10, and the pressure sensing element 10 will transmit the corresponding signal to the connector 30 after sensing, and then output the signal to the outside of the sensor 1.

[0072] Similarly, when the sensor 1 measures the temperature of the medium, a notch is provided on the side of the protective cover 70 away from the mounting base 80, and the medium can enter the protective cover 70 through the notch to contact the temperature sensing component 60. The temperature sensing component 60 transmits the sensed medium temperature signal to the pressure sensing component 10 through the mounting base 80. The pressure sensing component 10 is provided with an electrical connection hole, and the medium temperature signal can be successively transmitted to the connector 30 along the bottom of the pressure sensing component 10 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, thereby damaging the internal components of the sensor 1.

[0073] In addition, if Figure 3 , Figure 8 and Fig. 9As shown, the support member 20 is provided with a third positioning portion 23, and the shell 90 is provided with a fourth positioning portion 92, and the third positioning portion 23 is positioned and matched with the fourth positioning portion 92, wherein the third positioning portion 23 and the fourth positioning portion 92 can both play a positioning role, and the third positioning portion 23 is arranged on the support member 20, and the fourth positioning portion 92 is arranged on the shell 90. In this way, when the support member 20 is matched with the shell 90, the position between the support member 20 and the shell 90 can be calibrated by utilizing the cooperation of the third positioning portion 23 and the fourth positioning portion 92, so that the installation between the support member 20 and the shell 90 can be made more accurate and quick, thereby improving the assembly efficiency.

[0074] 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 100, the ceramic material can better press the sealing element 100, thereby ensuring the sealing performance of the sensor 1.

[0075] As an optional embodiment, the housing 90 and the connector 30 may be fixed by riveting, which can ensure the sealing of the seal 100. 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.

[0076] It should be noted that the connector 30, the pressure sensing component 10 and the support component 20 can form a detection part, which can protect the pressure sensing component, prevent the pressure sensing component 10 from colliding with the housing 90, and effectively ensure the connection between the pressure sensing component 10 and the connector 30 to ensure that its communication function is normal. The temperature sensing component 60, the protective cover 70, and the mounting base 80 can form a temperature sensing part. The temperature sensing part and the detection part are placed in the housing 90 in sequence, which can reduce the installation steps of the process and improve production efficiency.
