Description

TECHNICAL FIELD

[0001] The present application relates to a sensor, in particular to an integrated pressure and temperature sensor. BACKGROUND

[0002] Integrated pressure and temperature sensors are known in practice, which are capable of sensing not only the pressure of a fluid to be measured, but also the temperature of the fluid to be measured at the same time. Integrated pressure and temperature sensors can be widely used in application scenarios in which both pressure and temperature need to be ascertained, for example in vehicles, preferably in air conditioning systems of motor vehicles, cooling liquid systems of traction batteries, engine lubrication systems. For example, patent document CN102980714A discloses an integrated pressure and temperature sensor of this kind.

[0003] Integrated pressure and temperature sensors known in practice can have an integrated carrier assembly, on which a pressure sensor assembly and a temperature sensor assembly can be arranged. The carrier assembly can also be referred to as a T-shaped carrier. Typically, the carrier assembly can be made by injection molding. Due to the complex geometry of the known carrier assembly and the functions to be fulfilled, the injection molding process for manufacturing such a carrier assembly is very complex, the parting surface of the injection mold needs to be designed very ingeniously, which in turn generally leads to difficulties in manufacturing and high manufacturing costs of the integrated pressure and temperature sensor. In addition, it is unavoidable that ridges are produced on the carrier assembly at the site corresponding to the parting surface, which can damage the sealing ring and even cause a certain degree of leakage, so that the service life of the integrated pressure and temperature sensor is adversely affected. SUMMARY

[0004] It is the task of the present application to propose an integrated pressure and temperature sensor which can be advantageously manufactured, in particular the carrier assembly can be advantageously manufactured.

[0005] The task is solved by an integrated pressure and temperature sensor, comprising a housing having a chamber and a fluid inlet for introducing a fluid to be measured into the chamber, in which a carrier assembly, a pressure sensor assembly for sensing the pressure of the fluid to be measured and a temperature sensor assembly for sensing the temperature of the fluid to be measured are accommodated, the pressure sensor assembly and the temperature sensor assembly being arranged on the carrier assembly, the carrier assembly comprising a carrier main body and a carrier appendix separate from each other, the pressure sensor assembly being arranged on a first side of the carrier main body, the temperature sensor assembly being arranged on a second side of the carrier main body opposite the first side, the carrier appendix being connected to the carrier main body on the second side of the carrier main body, in particular only detachably connected.

[0006] Unlike the integrated pressure and temperature sensor known in practice with an integral carrier assembly, the integrated pressure and temperature sensor according to the application has a split carrier assembly, in particular a two-part carrier assembly, the individual components of which can be produced more advantageously, wherein the equipment outlay for producing the carrier assembly is reduced.

[0007] In particular when the individual components of the carrier assembly are produced in an injection-molding process, the injection mold can be simplified, wherein the design constraints of the parting surface are significantly reduced. The edge that influences the sealing that is present in the prior art can be avoided in an advantageous embodiment. In an advantageous embodiment, the individual mold parts of the injection mold can be opened in a different direction than in the prior art.

[0008] In some embodiments, the carrier body and the carrier attachment are integrally formed injection-molded parts, respectively.

[0012] In some embodiments, the tubular element can be made of a metallic material, for example of copper or stainless steel. In general, the tubular element can also be made of a good heat-conducting material, which can be filled with a heat-conducting filler in the tubular element. Thus, the heat of the fluid to be measured flowing outside the tubular element can be conducted via the tubular element and the heat-conducting filler to the temperature-sensing element.

[0013] In some embodiments, the fluid to be measured can be a working medium of an air-conditioning system of a motor vehicle, fuel of a motor vehicle or cooling liquid of a traction battery.

[0019] In some embodiments, the tubular element is swaged onto the first section.

[0020] In some embodiments, the first section has a plurality of vertical grooves extending in the longitudinal direction distributed in the circumferential direction.

[0021] In some embodiments, the first section is substantially cylindrical and / or the second section is cylindrical. Alternatively, the first section and / or the second section can also be elliptical cylindrical or can have another suitable cross-sectional shape.

Thus, a temperature-sensing signal related to the temperature generated by the temperature-sensing element can be output, in particular transmitted, via the pair of conductor tracks to a corresponding circuit assembly in order to ascertain a temperature value of the fluid to be measured by means of the temperature-sensing signal.

[0023] In some embodiments, the electrically conductive pins are held in the carrier attachment by a press fit, such that the carrier attachment is detachably held on the carrier body.

[0024] In some embodiments, the carrier attachment has one recess and / or one extrusion member for each electrically conductive pin, each electrically conductive pin being inserted with its free end into the respective recess and / or being extruded by the respective extrusion member.

[0025] In some embodiments, the carrier attachment has a second disc-shaped body having the pair of through-holes and / or a tip piece having the extrusion members. Preferably, the second disc-shaped body and the tip piece are connected by a second stem-shaped body. Further preferably, the tip piece and the second stem-shaped body define the recesses.

[0026] In some embodiments, one of the carrier body and the carrier attachment, in particular the carrier body, has a positioning pin and the other of the carrier body and the carrier attachment, in particular the carrier attachment, has a positioning hole cooperating with the positioning pin.

[0027] In some embodiments, the positioning pin projects axially from the free end section of the carrier body.

[0028] In some embodiments, the positioning hole is provided in the second disc-shaped body.

[0029] In some embodiments, the electrically conductive elements each have a contact projecting from the first side of the carrier body, the contact being electrically connected, for example by soldering, with an electrical circuit assembly which is configured to receive a temperature sensing signal of the temperature sensor assembly. Preferably, the electrical circuit assembly is also configured to receive a pressure sensing signal of the pressure sensor assembly.

[0030] In some embodiments, the pressure sensor assembly comprises a planar pressure sensing element which rests on the first side of the carrier body.

[0031] In some embodiments, the pressure sensing element can have a rectangular or circular contour.

[0032] In some embodiments, the pressure sensing element can be a capacitive pressure sensing element.

[0033] In some embodiments, a second sealing ring is provided between the pressure sensing element and the carrier body, the carrier body having a throughflow opening in the region enclosed by the second sealing ring, such that the fluid to be measured can pass from the fluid inlet via the throughflow opening to the pressure sensing element.

[0034] In some embodiments, the electrical circuit assembly is provided on the side of the pressure sensing element facing away from the carrier body, the second sealing ring sealing the contact with respect to the fluid to be measured.

[0035] In some embodiments, the housing is two-part.

[0036] In some embodiments, the housing comprises a hollow base element having a pot and a spout projecting from the bottom of the pot, the free end of the spout forming the fluid inlet, the first disc-shaped body of the carrier body resting on the bottom of the pot, the temperature sensor assembly being accommodated in the spout, and the housing further comprising a closure element which closes the open side of the pot. The closure element can be, for example, an injection-moulded part.

[0037] In some embodiments, the closure element is configured as a connector for connecting the integrated pressure and temperature sensor to an external device, for example to the vehicle network of a motor vehicle.

[0038] In some embodiments, the base element is made of a metallic material, for example of copper or stainless steel.

[0039] In some embodiments, the connecting piece has an external thread which is configured for screwing the integrated pressure and temperature sensor to the object to be measured. Preferably, the sealing of the base element relative to the object to be measured is achieved by means of a third sealing ring which is mounted on the connecting piece.

[0040] In some embodiments, the temperature sensor assembly can protrude beyond the fluid inlet, or alternatively, can be recessed relative to the fluid inlet.

[0051] Numerous example embodiments will now be described with reference to the drawing. It should be recognized that elements not essential to an understanding of the present disclosure can be omitted from the drawings for purposes of clarity and ease of illustration. Like reference numerals can be used to denote like parts or parts having the same function throughout the various figures. Numerous specific details are set forth in the following description in order to provide a thorough understanding of the implementations of the present disclosure. Those skilled in the art will recognize that not all specific details need be presented in order to be understood as the example embodiments can be practiced without all of the specific details given. The example embodiments are not to be construed as limiting.

[0052] Figure 1is an exploded view of an integrated pressure and temperature sensor 100 according to an embodiment of the present application. The integrated pressure and temperature sensor 100 comprises a housing 10. The housing 10 is two-part and comprises a hollow base element 5 and a closure element 6. The base element 5 can be made of a corrosion-resistant metal material, for example, copper or stainless steel. The base element 5 has a pot body and a connection piece 9 extending from the bottom of the pot body. The base element 5 can have a polygonal profile, by means of which the base element 5 can be manipulated by means of a spanner. The connection piece 9 of the base element 5 can have an external thread. The base element 5 can be screwed into a mounting interface of an object to be measured by means of the external thread with the addition of a sealing ring, which is also referred to herein as a third sealing ring 3, in order to detect a fluid to be measured of the object to be measured by means of the integrated pressure and temperature sensor 100. The free end of the connection piece 9 forms a fluid inlet 31 for the fluid to be measured. The fluid to be measured can enter the housing 10 via the fluid inlet 31. The closure element 6 is connected to the base element 5 and thus encloses a chamber of the housing 10. In the chamber of the housing 10, a temperature sensor assembly 20 for sensing the temperature of the fluid to be measured, a carrier assembly 30 and a pressure sensor assembly 40 for sensing the pressure of the fluid to be measured are accommodated. At present, a circuit assembly 50 is also accommodated in the chamber of the housing 10. The pressure sensor assembly 40 and the temperature sensor assembly 20 are arranged on the carrier assembly 30. The circuit assembly 50 is configured to receive a pressure sensing signal of the pressure sensor assembly 40 and a temperature sensing signal of the temperature sensor assembly 20, so that the temperature value and the pressure value of the fluid to be measured can be determined simultaneously. The circuit assembly 50 can advantageously be arranged on the side of the pressure sensor assembly 40 facing away from the carrier assembly 30. The temperature sensor assembly 20 is arranged on a second side of the carrier assembly 30 and is sealed with respect to the carrier assembly 30 by means of a first sealing ring 1. The pressure sensor assembly 40 is arranged on a first side of the carrier assembly 30 and is sealed with respect to the carrier assembly 30 by means of a second sealing ring 2. The carrier assembly 30 is sealed with respect to the base element 5 by means of a further sealing member 4, for example, a gasket.

[0053] Figures 2 to 4 shows a structural unit of the integrated pressure and temperature sensor 100. Figure 2 is an exploded view of the structural unit, Figure 3 is a perspective view of the structural unit in the assembled state, and Figure 4 is a longitudinal sectional view of the structural unit in the assembled state. The structural unit comprises a carrier assembly 30 and a temperature sensor assembly 20 mounted to the carrier assembly 30. The carrier assembly 30 is additionally sealed with respect to the base element 5 by means of Figures 5 to 8 is described in more detail.

[0054] Here, the carrier assembly 30 is two-part, comprising a carrier body 11 and a carrier appendix 12. The carrier body 11 and the carrier appendix 12 are each one-piece injection-molded parts. Due to the two-part construction of the carrier assembly 30, the carrier assembly 30 can be produced significantly more easily than known one-piece carrier assemblies, in particular by means of an injection-molding process, wherein the complexity of the injection mold can be significantly reduced.

[0055] The carrier body 11 has a first side and a second side opposite the first side. The pressure sensor assembly 40 is arranged on the first side of the carrier body 11, the temperature sensor assembly 10 is arranged on the second side of the carrier body 11, and the carrier appendix 12 is connected to the carrier body 11 on the second side of the carrier body 11. The carrier body 11 has a first disk-shaped body 13 and a first rod-shaped body 14 extending from the first disk-shaped body 13. The first disk-shaped body 13 has a recess 33 which can receive the second sealing ring 2 and the pressure sensor assembly 40. The pressure sensor assembly 40 can comprise a planar pressure sensing element, which in the present case has a substantially rectangular contour. Alternatively, the pressure sensing element can also have a circular contour or any other suitable contour shape. Typically, the pressure sensing element can be a capacitive pressure sensing element which has a pressure-sensitive surface. Upon application of the fluid to be measured on the surface, the capacitance of the pressure sensing element changes and a pressure sensing signal is thereby generated. This pressure sensing signal can be received and processed by a circuit assembly 50 held on the pressure sensor assembly 40 in order to obtain a pressure value of the fluid to be measured. The carrier body 11 can have a flow-through opening 32 in the region enclosed by the second sealing ring 2, through which the fluid to be measured can pass from the fluid inlet 31 through the annular channel between the base element 5 and the temperature sensor assembly 10 and then through the flow-through opening 32 into the recess 33 and thus to the pressure sensing element. The second sealing ring 2 prevents the fluid to be measured from passing beyond it in the radial direction, so that the region radially outside the second sealing ring 2 is a dry zone. The circuit assembly 50 is isolated from the fluid to be measured by the second sealing ring 2, the contact 19 connected to the circuit assembly 50, which will be explained below, being in the so-called dry zone.

[0056] The temperature sensor assembly 20 comprises a temperature sensing element 7 and a tubular element 8 having a closed end and an open end, the tubular element 8 being inserted with the open end onto the first rod-shaped body 14 of the carrier assembly 30, the temperature sensing element 7 being accommodated in the tubular element 8, the first sealing ring 1 explained above being fitted on the first rod-shaped body 14. Due to the two-part construction of the carrier assembly 30, the section of the first rod-shaped body 14 for receiving the first sealing ring 1 can be free of edges which would adversely affect the first sealing ring 1 itself and the tightness of the first sealing ring 1 on the first rod-shaped body 14 in the case of production of the carrier body 11 by means of an injection-molding process.

[0057] The first rod-shaped body 14 comprises a first section 15 with a larger cross section near the first disc-shaped body 13 and a free end section 17 with a smaller cross section. The tubular element 8 is inserted and fixed on the first section 15, and a step between the free end section 17 and the first section 15 forms a first axial stop for the first sealing ring 1. The carrier attachment 12 has an end face 27 (see Figure 8 ) facing the carrier body 11, which end face 27 adjoins the free end section 17 and forms a second axial stop for the first sealing ring 1, which is held axially between the first axial stop and the second axial stop. For the fixation of the tubular element 8 on the first section 15, the tubular element 8 can be swaged on the first section 15. Advantageously, the first section 15 can have a plurality of vertical grooves 16 distributed in the circumferential direction and extending in the longitudinal direction, which can release the stresses generated in the plastic matrix of the first section 15 during swaging, avoiding damage to the plastic material.

[0058] The carrier body 11 has a pair of conductor tracks injected in the plastic matrix, which each comprise one electrically conductive pin 18 projecting from the plastic matrix. Correspondingly, the carrier attachment 12 has a pair of through-holes 24, through which the electrically conductive pins 18 pass. The electrically conductive pins 18 are electrically connected to the temperature sensing element 7, in particular mechanically and electrically connected to each other by soldering, so that the temperature sensing element 7 is electrically connected to the circuit assembly 50 via the pair of conductor tracks. The pair of electrically conductive elements each has a contact 19 projecting from the first side of the carrier body 11, which is electrically connected to the circuit assembly 50, for example by soldering.

[0059] Here, the electrically conductive pins 18 are held in the carrier attachment 12 by a press fit, so that the carrier attachment 12 is stably detachably held on the carrier body 11. The carrier attachment 12 can have one recess 28 and one extrusion member 29 for each electrically conductive pin 18, each electrically conductive pin 18 being inserted with its free end into the respective recess 28 and being extruded by the respective extrusion member 29 in order to achieve a press fit, thereby stably holding both electrically conductive pins 18 in both recesses 28.

[0060] In an advantageous design, the carrier attachment 12 may have a second disc-shaped body 21 and an end piece 23, which are axially spaced apart and connected by a second rod-shaped body 22 extending axially. The second disc-shaped body 21 has the end face 27 and the pair of through holes 24. The end piece 23 has the pair of pressing members 29, and the end piece 23 and the second rod-shaped body 22 define the pair of grooves 28. The pair of grooves 28 and the pair of pressing members 29 may be arranged opposite each other with respect to the second rod-shaped body 22, particularly symmetrically. The pressing members 28 may be protrusions with cylindrical surfaces. For precise relative positioning during assembly of the carrier assembly 30, the carrier body 11 may have a locating pin 25, and the carrier attachment 12 may have a locating hole 26 that mates with the locating pin 25. Through the combined action of the positioning pin 25 and the positioning hole 26, as well as through the combined action of a pair of conductive pins 18, a pair of grooves 28 and a pair of pressing members 29, the carrier attachment 12 can be securely, detachably and precisely held on the carrier body 11.

[0061] Next, refer to Figure 1 Explanation as follows Figure 3 and Figure 4 The structural unit shown includes a temperature sensor assembly 20 and a carrier assembly 30, mounted within the base element 5 of the housing 10. With the seal 4 included, the structural unit rests against the bottom of the tank of the base element 5 with the first disc-shaped body 13 of the carrier body 11 of the carrier assembly 20 abutting it, and the temperature sensor assembly 10 is housed in the connecting pipe 9. Depending on the actual needs, the temperature sensor assembly 10 can extend from the open end of the connecting pipe 9, which serves as a fluid inlet 31, or retract relative to that open end.
