[0038] 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.

[0039] Reference below Figure 1-Figure 10 The pressure sensing component 10 according to the embodiment of the present invention is described. The pressure sensing component 10 is mainly used to measure the pressure of the medium.

[0040] like Figure 2 As shown, the pressure sensing component 10 according to the present invention includes: a connecting member 20 and a supporting member 11 .

[0041] like Figure 2 and Figure 8 As shown, the connecting member 20 is provided with a first positioning portion 21 and a first clamping portion 22, and the supporting member 11 is provided with a second positioning portion 111 positioned and matched with the first positioning portion 21 and a second clamping portion 112 clamped and matched with the first clamping portion 22; the first positioning portion 21 and the first clamping portion 22 are both protruded from the connecting member 20 toward the support member 11, or the second positioning portion 111 and the second clamping portion 112 are both protruded from the support member 11 toward the connecting member 20.

[0042] Since the first positioning portion 21 and the first clamping portion 22 on the connecting member 20 are both protruded from the connecting member 20 toward the support member 11, the second positioning portion 111 and the second clamping portion 112 of the support member 11 do not need to protrude toward the connecting member 20, and the size of the support member 11 can be reduced to a certain extent, thereby reducing the packaging and transportation costs of the support member 11, so as to facilitate large-scale batch production.

[0043] Similarly, since the second positioning portion 111 and the second clamping portion 112 of the support member 11 are both protruded from the support member 11 toward the connecting member 20, the first positioning portion 21 and the first clamping portion 22 on the connecting member 20 do not need to protrude toward the support member 11, and the size of the connecting member 20 can be reduced to a certain extent, thereby reducing the packaging and transportation costs of the connecting member 20, so as to facilitate large-scale batch production.

[0044] In some embodiments of the present invention, Figure 8 As shown, the first positioning portion 21 and the first clamping portion 22 are both protruded from the connecting member 20 toward the supporting member 11, the first positioning portion 21 is configured as a positioning protrusion, and the second positioning portion 111 is a positioning hole; the first clamping portion 112 is a buckle, and the second clamping portion 112 is a protrusion provided on the side wall of the supporting member 11. The structure is simple, which is convenient for reducing the size of the supporting member 11, thereby reducing the packaging and transportation costs of the supporting member 11.

[0045] In some embodiments of the present invention, Figure 8 As shown, there are two first positioning portions 21, and the two first positioning portions 21 have different shapes and / or different sizes; thus, foolproof matching between the support member 11 and the connecting member 20 can be achieved. Moreover, there are two first positioning portions 21, which can increase the number of positions for positioning matching between the connecting member 20 and the support member 11, thereby further improving the accuracy of assembly.

[0046] It should be noted that the different sizes of the two first positioning portions 21 may be different diameters or different lengths.

[0047] In some embodiments of the present invention, Figure 8 As shown, there are two first positioning parts 21, and the end surface of the connecting member 20 facing the support member 11 is circular. On this end surface, the distance between the centers of the two first positioning parts 21 is less than the diameter of the end surface. In other words, the line connecting the centers of the two first positioning parts 21 is not colinear with the center of the connecting member 20, so that the connecting member 20 can achieve foolproof cooperation with the support member 11.

[0048] In some embodiments of the present invention, Figure 8As shown, a clamping portion 23 is provided on the side of the connecting member 20 facing the supporting member 11, and the clamping portion 23 is suitable for abutting and cooperating with the supporting member 11. The first positioning portion 21 is provided on the clamping portion 23, and the clamping portion 23 can be staggered with the first clamping portion 22. The clamping portion 23 mainly plays a clamping role. The clamping portion 23 abuts and cooperates with the supporting member 11. It should be noted that when the connecting member 20, the pressure sensing member 12 and the supporting member 11 are press-fitted, when the clamping portion 23 presses the pressure sensing member 12 to a certain extent, the clamping portion 23 will abut and cooperate with the supporting member 11, so as to avoid excessive clamping force of the clamping portion 23 on the pressure sensing member 12, thereby causing damage to the pressure sensing member 12.

[0049] The first positioning portion 21 is arranged on the pressing portion 23, so that the first positioning portion 21 can be fixed, so that the setting of the first positioning portion 21 is more reliable and stable, and it is also convenient for the first positioning portion 21 to cooperate with the support member 11. The pressing portion 23 and the first clamping portion 22 are arranged alternately, that is, the pressing portion 23 and the first clamping portion 22 are two independent parts, so that interference between the pressing portion 23 and the first clamping portion 22 can be avoided, and the first clamping portion 22 can also be set according to actual working conditions during processing, which is more flexible to use.

[0050] In some embodiments of the present invention, Figure 8 As shown, there are two clamping parts 23 and two first positioning parts 21, and one first positioning part 21 is respectively provided on the two clamping parts 23. In other words, there can be two clamping parts 23, so that the setting of the clamping parts 23 can be more comprehensive, so that the pressure sensing part 12 and the support part 11 can be better pressed. One first positioning part 21 is respectively provided on the two clamping parts 23, so that the distribution of the first positioning parts 21 can be more comprehensive, avoiding the two first positioning parts 21 being too close to each other, which affects the assembly and positioning effects. It should be noted that, as can be seen from the above, two first clamping parts 22 can also be provided, and the two first clamping parts 22 are arranged between the two clamping parts 23.

[0051] In some embodiments of the present invention, Figure 8 As shown, a groove 231 is also provided on the pressing part 23. The groove 231 mainly plays a role in reducing weight. The groove 231 is provided on the pressing part 23, so that the weight of the pressing part 23 can be reduced without affecting the cooperation between the pressing part 23 and the pressure sensing element 12 and the supporting element 11, thereby reducing the weight of the sensor 1 and saving costs.

[0052] In some embodiments of the present invention, Figure 2 and Figure 3As shown, the pressure sensing component 10 also includes a pressure sensing member 12, which is arranged on the support member 11, and the connecting member 20 abuts against the pressure sensing member 12, and the connecting member 20 is electrically connected to the pressure sensing member 12. Among them, the pressure sensing member 12 is mainly used to sense the pressure of the medium. The pressure sensing member 12 is arranged on the support member 11, so that the pressure sensing member 12 can be fixed, so that the setting of the pressure sensing member 12 is more reliable and stable, and the pressure sensing member 12 can work better. The connecting member 20 abuts against the pressure sensing member 12, so that the connecting member 20 can further press the pressure sensing member 12, so that the pressure sensing member 12 can be more stable. Moreover, the pressure sensing member 12 is located between the support member 11 and the connecting member 20, so that the pressure sensing member 12 can also be protected. The connecting member 20 is electrically connected to the pressure sensing member 12, that is, the pressure sensing member 12 can transmit the sensed medium pressure signal to the connecting member 20, and then the connecting member 20 can transmit it to the outside of the sensor 1.

[0053] In some embodiments of the present invention, Figure 6 and Fig.10 As shown, the sensor 1 also includes a first connecting spring piece 30, which is arranged on the pressure sensing member 12. A connecting terminal 24 is also arranged at one end of the connecting member 20 facing the supporting member 11. The connecting terminal 24 is electrically connected to the first connecting spring piece 30, and the connecting terminal 24 is elastically connected to the first connecting spring piece 30.

[0054] Among them, the first connecting spring 30 mainly plays the role of electrical connection. The first connecting spring 30 is electrically connected to the pressure sensing element 12, so that the medium pressure signal sensed by the pressure sensing element 12 can be input to the first connecting spring 30, thereby facilitating the transmission of subsequent signals. The connecting terminal 24 mainly plays the role of electrical connection. The connecting terminal 24 is electrically connected to the first connecting spring 30, so that the signal transmitted from the pressure sensing element 12 to the first connecting spring 30 will be transmitted to the connecting element 20 through the connecting terminal 24, and then the signal can be transmitted to the outside of the sensor 1. Since the connecting terminal 24 is electrically connected to the first connecting spring 30, the connecting terminal 24 is set on the side of the connecting element 20 facing the support member 11. This setting is more reasonable and can shorten the distance between the connecting terminal 24 and the first connecting spring 30, thereby facilitating the electrical connection between the connecting terminal 24 and the first connecting spring 30. Compared with welding, the connection method using the first connecting spring 30 is simpler and can reduce costs.

[0055] Specifically, Fig.10As shown, the first connecting spring piece 30 includes a connecting portion 31, a contact portion 32 and a supporting portion 33. The connecting portion 31 is electrically connected to the pressure sensing element 12, the supporting portion 33 is connected to the connecting portion 31, the contact portion 32 is connected to the connecting portion 31, and the contact portion 32 is rotatably arranged on the supporting portion 33, and the connecting terminal 24 is electrically connected to the contact portion 32. Among them, the connecting portion 31 and the contact portion 32 both mainly play the role of electrical connection, and the supporting portion 33 can play the role of support and electrical connection. The connecting portion 31 is electrically connected to the pressure sensing element 12, so that the signal on the pressure sensing element 12 can be transmitted to the connecting portion 31. The supporting portion 33 is connected to the connecting portion 31, which can improve the stability of the connection between the connecting portion 31 and the supporting portion 33, and the supporting portion 33 can be used to support the connecting portion 31, so that the connection between the connecting portion 31 and the pressure sensing element 12 is more stable.

[0056] The contact portion 32 is connected to the connecting portion 31. It should be noted that the contact portion 32 and the connecting portion 31 are electrically connected, so that the signal transmitted from the pressure sensing element 12 to the connecting portion 31 is transmitted to the contact portion 32. Because the connecting terminal 24 is electrically connected to the contact portion 32, the signal transmitted to the contact portion 32 is further transmitted to the connecting terminal 24, and then transmitted to the outside by the connecting member 20.

[0057] The contact portion 32 is rotatably disposed on the support portion 33, that is, the contact portion 32 can rotate relative to the support portion 33. It should be noted that when the pressure sensing component 12 is press-fitted, the pressure sensing component 12 will be pre-installed first. During the pre-installation, the connection terminal 24 on the connector 20 will pre-press the contact portion 32, and the contact portion 32 will rotate relative to the support portion 33 under the pressure of the connection terminal 24, thereby ensuring that the connection terminal 24 and the contact portion 32 have good contact. After the pre-pressing is completed, formal pre-pressing will be performed, and the connection terminal 24 will further squeeze the contact portion 32, so that the contact portion 32 will further rotate relative to the support portion 33, thereby enabling the connection terminal 24 and the contact portion 32 to better cooperate.

[0058] In addition, if Fig.10As shown, in the pressing direction of the connection terminal 24, the maximum distance between the connection terminal 24 and the connection part 31 is a, the maximum distance between the support part 33 and the connection part 31 is b, and the maximum distance between the contact part 32 and the connection part 31 is c. The relationship between a, b and c is: b<a<c. That is to say, in the pressing direction of the connection terminal 24, the maximum distance between the connection terminal 24 and the connection part 31 and the maximum distance between the support part 33 and the connection part 31, as well as the maximum distance between the connection terminal 24 and the connection part 31 and the maximum distance between the contact part 32 and the connection part 31 need to meet a certain range, that is, the maximum distance between the connection terminal 24 and the connection part 31 needs to be greater than the maximum distance between the support part 33 and the connection part 31, so as to avoid the pressure sensing part 12 being damaged by excessive force during the press-fitting process. The maximum distance between the connection terminal 24 and the connection part 31 also needs to be less than the maximum distance between the contact part 32 and the connection part 31, so as to avoid the first connection spring 30 and the connection member 20 from having poor contact, resulting in the signal being unable to be transmitted normally.

[0059] In some embodiments of the present invention, Figure 3 and Figure 6 As shown, the sensor 1 also includes a second connecting spring piece 40, which is connected to the side of the pressure sensing member 12 adjacent to the support member 11, and the support member 11 is provided with a through hole 115, and the second connecting spring piece 40 penetrates the through hole 115. Among them, the second connecting spring piece 40 mainly plays the role of electrical connection. The through hole 115 can play the role of positioning and installation. The second connecting spring piece 40 penetrates the through hole 115, so that the through hole 115 has a positioning effect on the second connecting spring piece 40, which can improve the accuracy of the assembly of the pressure sensing member 12, and can also protect the second connecting spring piece 40 to a certain extent. Therefore, the second connecting spring piece 40 is connected to the side of the pressure sensing member 12 adjacent to the support member 11, which is more reasonable and convenient for the second connecting spring piece 40 to cooperate with the through hole 115. It should be noted that in order to make the sensor 1 work more safely, the sensor 1 needs to be grounded. Specifically, the second connecting spring piece 40 can be electrically connected to the housing 50 through the through hole 115, so that the grounding of the sensor 1 can be achieved.

[0060] The sensor 1 according to the present invention comprises: the pressure sensing component 10 described in the above embodiment. The sensor 1 in the present application may be a temperature and pressure sensor 1, which can measure the pressure and temperature of the corresponding medium.

[0061] By both the first positioning portion 21 and the first clamping portion 22 protruding from the connecting member 20 toward the supporting member 11, or the second positioning portion 111 and the second clamping portion 112 protruding from the supporting member 11 toward the connecting member 20, the size of the supporting member 11 or the connecting member 20 is reduced, thereby reducing the packaging and transportation costs of the pressure sensing component 10, and ultimately reducing the packaging and transportation costs of the sensor 1.

[0062] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the sensor 1 further includes a housing 50, the support member 11 is provided with a third positioning portion 113, the housing 50 is provided with a fourth positioning portion 53, and the third positioning portion 113 is positioned and matched with the fourth positioning portion 53. In this way, when the support member 11 is matched with the housing 50, the position between the support member 11 and the housing 50 can be calibrated by using the cooperation of the third positioning portion 113 and the fourth positioning portion 53, so that the installation between the support member 11 and the housing 50 can be made more accurate and faster, thereby improving the assembly efficiency.

[0063] In some embodiments of the utility model, the support member 11 is provided with a matching portion 114, and the matching portion 114 is limitedly matched with the side wall surface of the pressure sensing member 12. The matching portion 114 can play a limiting role. The matching portion 114 is provided on the support member 11, so that when the pressure sensing member 12 is placed on the support member 11, the matching portion 114 can limit the side wall surface of the pressure sensing member 12, thereby limiting the movement of the pressure sensing member 12 in the horizontal direction, thereby improving the position accuracy of the pressure sensing member 12, so that the pressure sensing member 12 can work better.

[0064] In addition, if Figure 2 and Figure 3 As shown, the sensor 1 also includes a temperature sensing component 60, which includes: a temperature sensing element 61, a protective cover 62 and a mounting base 63. One end of the mounting base 63 is matched with the protective cover 62, and the temperature sensing element 61 is connected to a side of the mounting base 63 adjacent to the protective cover 62, and the temperature sensing element 61 is arranged in the protective cover 62. Among them, the temperature sensing element 61 is mainly used to sense the temperature of the medium, and the temperature sensing element 61 can be an NTC thermistor. The protective cover 62 mainly plays a protective role. The mounting base 63 mainly plays a mounting role.

[0065] The temperature sensing element 61 is arranged in the protective sleeve 62, so that the protective sleeve 62 can be used to protect the temperature sensing element 61, and the medium can be prevented from directly impacting the temperature sensing element 61, so that the temperature sensing element 61 can work better. The temperature sensing element 61 is connected to the side of the mounting base 63 adjacent to the protective sleeve 62, so that the temperature sensing element 61 can be fixed, so that the setting of the temperature sensing element 61 is more reliable and stable, so that the temperature sensing element 61 can work better. It is also convenient for the temperature sensing element 61 to be installed and matched with the protective sleeve 62, and then it is convenient for the protective sleeve 62 to protect the temperature sensing element 61.

[0066] It should be noted that since the temperature sensing component 61 is installed on the mounting base 63, the mounting base 63 is matched with the protective cover 62. This arrangement is more reasonable. While achieving the installation and matching of the mounting base 63 and the protective cover 62, it is also convenient for the temperature sensing component 61 to match with the protective cover 62.

[0067] In addition, if Figure 3 , Figure 5 and Fig. 9 As shown, a first limiting portion 51 is provided on the housing 50, a second limiting portion 621 is provided on the protective sleeve 62, and a third limiting portion 631 is provided on the mounting base 63. The second limiting portion 621 and the third limiting portion 631 are respectively matched with the first limiting portion 51. The first limiting portion 51, the second limiting portion 621 and the third limiting portion 631 can all play a limiting role. The first limiting portion 51 is provided on the housing 50, and the second limiting portion 621 is provided on the protective sleeve 62. In this way, when the protective sleeve 62 is installed with the housing 50, the first limiting portion 51 and the second limiting portion 621 cooperate to install more accurately, and the protective sleeve 62 can be prevented from rotating relative to the housing 50, so that the sensor 1 can work better. Similarly, the third limiting portion 631 is arranged on the mounting base 63, and the first limiting portion 51 is arranged on the shell 50. In this way, when the mounting base 63 and the shell 50 are installed, the first limiting portion 51 and the third limiting portion 631 cooperate to achieve more accurate installation and avoid the mounting base 63 from rotating relative to the shell 50, so that the sensor 1 can work better.

[0068] Furthermore, if Figure 5As shown, in the axial direction of the protective sleeve 62, the second limiting portion 621 is aligned with the third limiting portion 631. As can be seen from the above, the second limiting portion 621 and the third limiting portion 631 are both matched with the first limiting portion 51, so in the axial direction of the protective sleeve 62, the second limiting portion 621 is aligned with the third limiting portion 631, so that the second limiting portion 621 and the third limiting portion 631 can be matched with the first limiting portion 51 at the same time, and after the second limiting portion 621 and the third limiting portion 631 are matched with the first limiting portion 51, the position between the protective sleeve 62 and the mounting base 63 can also be kept relatively stable, so that the temperature sensing component 60 can be kept relatively stable, and the sensor 1 can work better.

[0069] In addition, if Figure 3 As shown, a step portion 52 is provided in the housing 50, and a matching surface 622 is also provided on the protective sleeve 62. In the first axial direction of the protective sleeve 62, the matching surface 622 is limitedly matched with the surface of the step portion 52. A protective member 632 is provided at one end of the mounting base 63 away from the protective sleeve 62. In the second axial direction of the protective sleeve 62, the protective member 632 is abutted against the pressure sensing member 12. The second axial direction of the protective sleeve 62 is opposite to the first axial direction of the protective sleeve 62. Among them, the step portion 52 and the matching surface 622 can both play a role in limiting. The step portion 52 is provided in the housing 50, and the matching surface 622 is provided on the protective sleeve 62. In this way, when the protective sleeve 62 is installed on the housing 50, the protective sleeve 62 can be limited in the axial direction of the protective sleeve 62 by using the matching of the step portion 52 and the matching surface 622, so that the installation of the protective sleeve 62 can be more accurate, the assembly efficiency is improved, and the setting of the protective sleeve 62 can also be made more stable.

[0070] The protective member 632 mainly plays a protective role. The protective member 632 is set at one end of the mounting base 63 away from the protective sleeve 62, so that in the second axial direction of the protective sleeve 62, the protective member 632 can abut against the pressure sensing member 12, so that the protective member 632 can be used to eliminate the gap between the pressure sensing member 12 and the mounting base 63, thereby avoiding the collision between the pressure sensing member 12 and the mounting base 63, thereby affecting the normal use of the sensor 1. It should be noted that the second axial direction of the protective sleeve 62 is opposite to the first axial direction of the protective sleeve 62. Specifically, the first axial direction of the protective sleeve 62 is the direction of the pressure sensing member 12 toward the protective sleeve 62, and the second axial direction of the protective sleeve 62 is the direction of the protective sleeve 62 toward the pressure sensing member 12.

[0071] In addition, if Figure 2 and Figure 3As shown, the sensor 1 also includes a seal 70, which can be a sealing ring. The seal 70 is spaced apart from the mounting base 63, and the seal 70 is sealingly disposed between the pressure sensing component 12 and the housing 50. Among them, the seal 70 mainly plays a sealing role. It should be noted that the seal 70 is sleeved on the mounting base 63, so the seal 70 is spaced apart from the mounting base 63, that is, there is a gap between the seal 70 and the mounting base 63, which facilitates the installation of the seal 70. Moreover, the seal 70 is sealingly disposed between the pressure sensing component 12 and the housing 50, so that the seal 70 can seal the gap between the pressure sensing component 12 and the housing 50.

[0072] It should be noted that the seal 70 can separate the gap between the pressure sensing element 12 and the housing 50 into two areas, that is, the inside of the seal 70 is the medium contact area, and the outside of the seal 70 is the medium isolation area, and the third limit portion 631 is also a pressure inlet while limiting, and the medium can enter the medium contact area from the third limit portion 631, and then can perform contact sensing with the pressure sensing element 12. 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 621 and the third limit portion 631 to perform contact sensing with the pressure sensing element 12, and the pressure sensing element 12 will transmit the corresponding signal to the connector 20 after sensing, and then output the signal to the outside of the sensor 1.

[0073] As an optional embodiment, the pressure sensing element 12 is a ceramic element. That is, the circuit board in the pressure sensing element 12 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 12 presses the sealing element 70, the ceramic material can better press the sealing element 70, thereby ensuring the sealing of the sensor 1.
