Description

Technical Field

[0001] This invention relates to a mounting bracket for fixing a temperature sensor, particularly in an electric motor. The invention also relates to a method for manufacturing the mounting bracket. Background Technology

[0002] It is known to include temperature sensors in motor assemblies to monitor their operational health. For example, in an electric motor of an electric drive unit, a temperature sensor can be used to sense the temperature of the electrical conductors of the stator of the motor assembly.

[0003] Typically, temperature sensors are attached near the stator windings to measure their temperature. Known solutions use tape or hot glue. However, in the high-temperature and high-vibration environments of motors, this solution may have insufficient reliability and / or durability.

[0004] In other cases, the plastic retainer is manually assembled with the temperature sensor and stator winding temperature targeting device. These cases require the stator to be designed to include a dedicated stator winding temperature targeting device for assembly with the temperature sensor and plastic retainer, which means increased design, manufacturing, and assembly complexity, resulting in increased costs. Summary of the Invention

[0005] Therefore, the object of the present invention is to provide a solution for fixing temperature sensors, particularly in motors, which improves upon existing solutions and overcomes the aforementioned disadvantages.

[0006] The object of the present invention is achieved by the mounting bracket for fixing a temperature sensor according to claim 1, particularly for fixing it in a motor.

[0007] The mounting bracket includes a fixing component and a retaining component. The fixing component is configured to fix to the target to be sensed, particularly to the busbar of a motor. The retaining component is used to hold the temperature sensor and includes a retaining section configured to receive and secure the temperature sensor along the insertion direction.

[0008] The fixing device is characterized in that at least a portion of the fixing component is integral with at least a portion of the holding section and is made of a thermally conductive material, particularly a thermally conductive material with a thermal conductivity greater than 15 W / (mK), preferably greater than 50 W / (mK).

[0009] Because the fixing component and the holding component are constructed as a single unit, the temperature of the target can be sensed once the sensing part of the temperature sensor comes into thermal contact with the holding component.

[0010] Therefore, the mounting bracket allows the temperature sensor to be fixed to the target being sensed, and also allows for remote sensing of the target via a single component through heat conduction. This reduces the number of parts or custom design or manufacturing steps involved in mounting the temperature sensor.

[0011] In particular, when the thermal conductivity value is higher than 15 W / (mK), preferably higher than 50 W / (mK), the portion made of thermally conductive material conducts heat to ensure reliable sensing of the temperature of the target to be sensed.

[0012] According to one aspect of the invention, the entire retaining component may be integral with the portion of the retaining section made of thermally conductive material, particularly with the entire retaining section or the entire retaining component. Increasing the proportion of retaining and / or retaining components made of thermally conductive material improves the thermal conductivity of the retaining bracket.

[0013] According to one aspect of the invention, the thermally conductive material may include a metal, and in particular, the thermally conductive material may be a metal. Regarding the achievement of desired properties, particularly regarding thermal conductivity, tensile strength, corrosion resistance, chemical compatibility, and / or electromagnetic properties, the metal can be highly customizable.

[0014] According to one aspect of the invention, the metal may include copper, and in particular, the metal may be copper-based. Specifically, the metal may include deoxidized copper, or copper alloys, such as copper-tin alloys, such as bronze, or copper-nickel alloys or copper-silicon alloys. These materials may have increased thermal conductivity, which can improve the accuracy and speed of temperature sensing by the received temperature sensor.

[0015] According to one aspect of the invention, the thermally conductive material can have a tensile strength greater than 250 MPa, particularly greater than 350 MPa, and preferably greater than 500 MPa. When a material with these tensile strengths is selected, the stability of the temperature sensor received and secured in the holding component is improved, thereby reducing the risk of damage due to vibration.

[0016] According to one aspect of the invention, the portion made of thermally conductive material is a stamped and bent sheet. In particular, the entire mounting bracket can be a stamped and bent sheet. This configuration improves the cost efficiency of bracket manufacturing.

[0017] According to one aspect of the invention, the retaining member can be bent relative to the holding member at an angle between 45° and 135°, particularly between 60° and 120°, and preferably between 80° and 100°. Bending the retaining member relative to the holding member reduces the fixed extension in the extension direction of the retaining member and / or the holding member. This is particularly advantageous in confined environments, such as in motor housings. Therefore, the bent holding member improves the compactness of the mounting bracket when the retaining member is fixed to the target to be sensed, particularly a busbar.

[0018] According to one aspect of the invention, the retaining member may include at least one additional retaining section configured to receive and secure a corresponding additional temperature sensor, particularly along a direction parallel to the insertion direction. In this configuration, the temperature of the target to be sensed can be sensed by a second temperature sensor received in the other retaining section. This provides a second temperature signal, which can provide increased reliability of the measured temperature value through signal redundancy. Therefore, to further improve the reliability of temperature measurement, the retaining member may include more retaining sections, such as three retaining sections, configured to receive more (e.g., three each) temperature sensors.

[0019] According to one aspect of the invention, each retaining section may include a base, a cover, and two sides arranged to form a corresponding slot, particularly a rectangular slot, for receiving a corresponding temperature sensor. In this configuration, the temperature sensor can be manually inserted into each slot, thereby improving the ease of assembling the temperature sensor or multiple temperature sensors with the mounting bracket.

[0020] According to one aspect of the invention, each retaining section may include a stop portion configured to stop along the insertion direction, particularly engaging the distal end of a temperature sensor received in the retaining section. This improves the stability of the temperature sensor received in the slot.

[0021] According to one aspect of the invention, the base and the cover can be engaged by a retaining device, particularly a snap-locking device, specifically snapped together. In particular, the cover may include a latching tongue, and the base may include an opening configured to latch the latching tongue. Using a retaining device configured in this way, the groove can be formed quickly and easily during the manufacture of the fixing bracket, thereby improving manufacturing cost efficiency.

[0022] According to one aspect of the invention, each retaining section may include at least one spring arm configured to engage with a corresponding temperature sensor. Specifically, at least one spring arm may extend into a groove, particularly from the cover portion. The spring arm improves the stability of the temperature sensor received in the retaining section, thus counteracting vibration exposure.

[0023] According to one aspect of the invention, the fixing member may include a through hole, particularly a through hole configured to receive a fastener for securing the fixing member to the target to be sensed. In this configuration, the fixing member can be easily secured to the target to be sensed. In particular, in the case of a motor, the fixing member can be secured to any busbar of the motor, and is therefore applicable to a wider variety of motor types.

[0024] According to one aspect of the invention, the retaining member can be configured to be compressed between a busbar of the motor and another member, preferably a motor housing portion or a second busbar. When the retaining member is compressed between the busbar and the other member, thermal conduction at the surface interface between the busbar and the retaining bracket increases. Therefore, the temperature measured by the temperature sensor received in the holding section has higher accuracy.

[0025] According to one aspect of the invention, at least one of the cover, base, and side portions may include a first shape-fitting element facing into the groove and configured to achieve a shape-fitting connection with a second shape-fitting element of the received temperature sensor. In particular, the first shape-fitting element may be a recess, preferably a punch.

[0026] The present invention also relates to a sensor assembly comprising a mounting bracket and a temperature sensor, wherein the temperature sensor is received in a holding section of the mounting bracket, particularly in a slot of the holding section.

[0027] According to one aspect of the sensor assembly, the retaining section may include a press-fit portion that presses against the temperature sensor. This can further enhance the robustness of the secure hold of the temperature sensor received in the retaining section.

[0028] In one aspect, the sensor assembly also includes a busbar, wherein a fixing component is secured to the busbar, particularly by means of fasteners received in through holes in the fixing component and fastened to the busbar. The fastening of the fixing component to the busbar is cost-effective and suitable for a wider variety of motor types.

[0029] In one aspect of the sensor assembly, the temperature sensor can be a negative temperature coefficient (NTC) sensor. These sensors can offer improved accuracy and reliability, and are particularly well-suited for sensing temperatures within motor housings.

[0030] In one aspect of the sensor assembly, the temperature sensor can extend along the elongation direction, particularly along the insertion direction, and the temperature sensor can have an angular shape, particularly a rectangular shape, in a plane orthogonal to the elongation direction. This improves the rotational stability of the temperature sensor about the insertion direction received in the holding member.

[0031] In one aspect of the sensor assembly, the base may have an extension at least as long as the temperature sensor extends along its elongation direction. When a portion made of thermally conductive material comprises the entire base, the contact surface between the temperature sensor and the thermally conductive material is thus increased. Consequently, temperature sensing of the base, which is thermally connected to a fixed component configured to be fixed to the target to be sensed, is improved.

[0032] In one aspect of the sensor assembly, the temperature sensor includes a second shape-fitting element, particularly a protrusion or bump, formed on its outer surface, wherein the second shape-fitting element is configured to achieve a shape-fitting connection with the first shape-fitting element when the temperature sensor is received in a slot.

[0033] The object of the present invention is also achieved by a method for manufacturing a fixation bracket according to any of the above aspects. The method for manufacturing the fixation bracket includes the following steps:

[0034] (a) Provide a metal sheet, particularly a metal sheet made of a thermally conductive material, especially a thermally conductive material with a thermal conductivity greater than 15 W / (mK), preferably greater than 50 W / (mK).

[0035] (b) A fixing member and a retaining member are stamped in a metal sheet, the fixing member being configured to be fixed to a target to be sensed, particularly to a busbar of a motor, the retaining member being used to retain a temperature sensor, the retaining member including a retaining section, wherein a portion of the fixing member is integral with at least a portion of the retaining section, and

[0036] (c) Bending the stamped metal sheet such that the holding section is configured to receive and secure the temperature sensor along the insertion direction.

[0037] This method allows for the cost-effective manufacture of the fixation bracket of the present invention, thereby providing the aforementioned benefits.

[0038] The object of the present invention is also achieved by a method for manufacturing a sensor assembly according to any of the foregoing aspects. The method for manufacturing the sensor assembly includes the following steps:

[0039] (a) Provide a fixing bracket according to one of the above aspects, or manufacture according to the above method,

[0040] (b) The temperature sensor is received in the holding section of the fixed bracket, and

[0041] (c) Secure the temperature sensor in the holding section, particularly by crimping; crimp the mounting bracket onto the temperature sensor and / or frictionally engage the temperature sensor with the spring arm.

[0042] Furthermore, the present invention relates to a method for securing a sensor assembly according to one of the above aspects or manufactured by means of the above aspects to a busbar. The method for securing the sensor assembly includes the following steps: (i) arranging a surface (particularly a plane) of a fixing member in contact with a surface (particularly a plane) of a busbar (particularly a busbar of an electric motor), (ii) passing a fastener through a through-hole in the fixing member, and (iii) fastening the fastener through the through-hole to the busbar.

[0043] This fixing method ensures thermal contact between the fixing component and the busbar. In particular, the structural features of the fixing component allow for a compact arrangement of the temperature components and the busbar. This is especially beneficial in the confined, oil-immersed environment of a motor housing.

[0044] According to one aspect of the fastening method, step (ii) may include passing a fastener through a hole in the busbar, and step (iii) may include screwing the fastener into a nut on the fastening mating member. This can provide improved fastening pressure without impairing the conductivity of the busbar. Attached Figure Description

[0053] In the following detailed description of the embodiments, the same reference numerals identified in different drawings and / or different portions of the drawings refer to the same elements. Furthermore, unless explicitly stated otherwise... Figures 1 to 3 The structural features of the objects shown are not drawn to scale.

[0054] The technical features and their associated advantages or effects described in the following embodiments may be combined together or independently with or adapted to any aspect or embodiment of the invention, thereby creating other possible embodiments or aspects of the invention.

[0055] Now refer to Figure 1 and Figure 2 Describe the mounting bracket and sensor assembly. Figure 1 A mounting bracket 1 according to a first embodiment of the present invention is shown, which is used to fix two temperature sensors 200 together to form a sensor assembly 100 according to a second embodiment of the present invention.

[0056] The mounting bracket 1 can be used to fix the temperature sensor 200 in the motor, for example, in the motor housing.

[0057] The mounting bracket 1 can be specifically configured to fix the temperature sensor 200 to the busbar of the electric motor in the electric drive unit of the electric vehicle to sense the temperature of the busbar. For example, the mounting bracket 1 can be configured to fix the temperature sensor 200 to the busbar of the electric motor stator, or to the busbar of the electric motor inverter, or to the connection between the busbar of the electric motor stator and the busbar of the electric motor inverter.

[0058] However, in alternative embodiments of the invention, the mounting bracket 1 may also be configured to attach one or more temperature sensors 200 to different parts of the motor to sense different targets, such as sensing the windings of the motor stator. In other alternative embodiments of the invention, the mounting bracket 1 may also be configured to attach one or more temperature sensors 200 to a busbar of a generator, or to a busbar in a busbar arrangement outside the motor.

[0059] In this embodiment, the sensor assembly 100 includes two temperature sensors 200, but the mounting bracket may be adapted to fix, for example, only one or three temperature sensors 200 to the target to be sensed.

[0060] According to the invention, the material used for fixing bracket 1 is thermally conductive, particularly having a thermal conductivity greater than 15 W / (mK), preferably greater than 50 W / (mK). Preferably, the material also has a tensile strength greater than 250 MPa, more preferably greater than, particularly greater than, and 350 MPa, and more preferably greater than 500 MPa.

[0061] The fixing bracket 1 can be obtained, for example, by stamping and bending a sheet of metal, preferably a copper-nickel-silicon alloy or a copper-tin alloy (e.g., bronze). In a variation, the fixing bracket of the present invention can also be obtained by stamping and bending a sheet of copper-nickel alloy, copper-silicon alloy, or deoxidized copper that may include phosphorus.

[0062] Although in this embodiment the entire fixing bracket 1 is made of sheet metal, in other embodiments of the invention only a portion of the fixing bracket 1 is made of metal, particularly of stamped and bent sheet metal.

[0063] Temperature sensor 200 may be a negative temperature coefficient (NTC) thermistor. Specifically, each temperature sensor 200 includes an NTC sensing element 201, a protective package 203, and a signal line 205 connected to the sensing element 201. The NTC sensing element 201... Figure 1 Invisible above, but Figure 2 As can be seen above. Here, signal line 205 includes a synthetic fluoropolymer insulating sheath, here perfluoroalkoxy (PFA), and protective encapsulation 203 is also made of a synthetic fluoropolymer, here polytetrafluoroethylene (PTFE).

[0064] The protective package 203 has an elongated shape along the extending direction E and a rectangular cross-section in a plane orthogonal to the extending direction E. At the distal end 207 of the temperature sensor 200, the protective package 203 includes a chamfer 209 configured to facilitate insertion of the temperature sensor 200 into a slot, as described below.

[0065] According to the present invention, the fixing bracket 1 includes a fixing component 3 and a retaining component 5. According to the present invention, the fixing component 3 and the retaining component 5 are integral and include a thermally conductive material, particularly being made entirely of a thermally conductive material.

[0066] The fixing member 3 is bent at an angle relative to the retaining member 5, the angle being between 80° and 100°. The fixing member 3 is configured to be fixed to the target to be sensed. In this embodiment, the fixing member 3 includes a centrally located through hole 7 stamped into the fixing member 3 and two support tongues 9. The through hole 7 is configured to receive fasteners for securing the fixing member 3 to the target to be sensed (here, the busbar). The support tongues 9 are configured to clamp the busbar. Alternatively, other means suitable for fixing the support to the motor can be used.

[0067] The retaining member 5 is configured to retain the temperature sensor 200. Specifically, the retaining member 5 includes a first retaining section 11a and a second retaining section 11b. One of the two temperature sensors 200 is received in the first retaining section 11a along the insertion direction I1, and the second temperature sensor 200 is received in the second retaining section 11b along the insertion direction I2 parallel to the insertion direction I1.

[0068] Each retaining section 11a, 11b includes a base 13, a cover 15, and sides 17a, 17b, arranged to form a groove 19. Each groove 19 has a rectangular cross-section in a plane orthogonal to the insertion directions I1, I2, matching the rectangular shape of the protective package 203. Figure 1 As shown, in the sensor assembly 100, each temperature sensor 200 is received in a corresponding slot 19 along the corresponding insertion direction I1, I2.

[0069] In this embodiment, the base 13 of the corresponding retaining sections 11a and 11b is integral and coplanar.

[0070] Each holding section 11a, 11b also includes a stop 21 at the distal end of the receiving component 5 for stopping the temperature sensor 200 received in the slot 19.

[0071] According to this embodiment, each retaining section 11a, 11b includes a spring arm 23 protruding from the corresponding cover 15 into the groove 19 for resilient engagement with a temperature sensor 200 received in the groove 19. Therefore, the spring arm 23 provides stability to the temperature sensor 200 received in the groove 19 and increases the contact pressure between the temperature sensor 200 and the base 13 to improve thermal contact.

[0072] Furthermore, the spring arm 23 protrudes at least partially from the cover 15 into the slot 19 in the insertion directions I1, I2, thus advantageously increasing the pull-out force required to remove the temperature sensor 200 from the slot 19, and to a lesser extent increasing the insertion force required to insert the temperature sensor 200 into the slot 19.

[0073] Each retaining section 11a, 11b may further include a crimping portion 25, wherein two metal tongues adjacent to or part of the groove 19 are crimped onto the received temperature sensor 200 to further increase the grip and stability of the temperature sensor 200 received in the groove 19. Thus, the temperature sensor 200 becomes fixed in the groove 19, and thermal contact is further improved. Therefore, the cover portion 15, including the spring arm 23, together with the stop portion 21, allows the temperature sensor 200 to be received in the groove 19, and the crimping portion 25 secures the received temperature sensor 200 therein. Thus, the temperature sensor 200 is fixed in two different positions, achieving stable positioning and thermal contact.

[0074] Figure 2 It shows along Figure 1 A cross-sectional view of the sensor assembly 100 along line C.

[0075] Figure 2 A temperature sensor 200 is shown inserted into a slot 19 of a retaining section 11a along the insertion direction I1, and includes a signal line 205 and a protective package 203 that encapsulates the sensing element 201. Figure 2 The base 13, cover 15, and side 17a of the retaining section 11a are also shown. A spring arm 23 protrudes from the cover 15 and elastically engages with the temperature sensor 200. A crimping part 25 secures the temperature sensor 200 in the groove 19.

[0076] The base 13 includes a first form-fitting element, which is a punch 27 formed in the surface of the base 13 facing the slot 19. The punch 27 is configured to achieve a form-fitting connection with a second form-fitting element, which is a bump 211 formed in the outward-facing surface 203a of the protective package 203. The form-fitting connection between the punch 27 and the mating bump 211 has a foolproof function. Specifically, the form-fitting elements 27, 211 are configured to detect, for example, incorrect insertion of the temperature sensor 200 into the slot 19, insufficient insertion distance into the slot 19, or insertion of the temperature sensor in an inverted manner.

[0077] The mounting bracket 1 and the sensor assembly 100 provide the advantages of the invention summarized above. Specifically, the mounting bracket 1 can acquire the temperature of the target to be sensed (here, the busbar) by means of its thermal conductivity.

[0078] Therefore, the mounting bracket allows the temperature sensor to be simultaneously and integrally fixed to the target being sensed, and allows the target's temperature to be sensed remotely via thermal conductivity and heat transfer from the integrated component. This reduces the number of parts or custom design or manufacturing steps involved in mounting the temperature sensor.

[0079] In particular, when the thermal conductivity value is higher than 15 W / (mK), preferably higher than 50 W / (mK), the portion made of thermally conductive material conducts heat to ensure reliable sensing of the temperature of the target to be sensed.

[0080] Figure 3 A mounting bracket and sensor assembly according to an alternative embodiment of the invention are shown. Figure 3 The fixed bracket 1' and the corresponding sensor assembly 100' shown differ from the fixed bracket 1 and the corresponding sensor assembly 100' only in the configuration of the retaining component 5'. The fixed bracket 1' or sensor assembly 100' not described have the same features as the fixed bracket 1 and sensor assembly 11 described above.

[0081] Compared to the fixed bracket 1, which has only one spring arm 23 for each retaining section 11a, 11b, the retaining member 5' includes two spring arms 23 arranged along the respective insertion directions I1, I2 for each of its retaining sections 11a, 11b. Unlike the first embodiment, the retaining member 5' does not include a press-fit portion. Instead, in the retaining member 5', the retaining sections 11a, 11b are formed by rearwardly folding a portion 16 of a stamped sheet over the base 13 and sides 17a', 17b', the rearwardly folded portion 16 corresponding to the combined cover portion 15' of the retaining sections 11a, 11b.

[0082] The folded-back portion 16 corresponding to the combined cover portion 15' engages with the base portion 13 via a retaining device 29. Here, the folded-back portion 16 corresponding to the combined cover portion 15' includes a hook-shaped latch tongue 31 configured to snap and hook into the opening 33, and the base portion 13 includes an opening 33 configured to receive the latch tongue and snap and lock with the latch tongue, in particular the latch tongue 31.

[0083] exist Figure 4 The present invention illustrates a method for manufacturing a fixing bracket 1 according to a fifth embodiment of the present invention.

[0084] The method includes step A of providing a copper-nickel-silicon alloy sheet, the sheet having a thermal conductivity greater than 15 W / (mK), preferably greater than 50 W / (mK), and a tensile strength greater than 250 MPa, preferably greater than, particularly greater than, and 350 MPa, preferably greater than 500 MPa.

[0085] The method further includes step B: stamping a fixing member 3 and a retaining member 5 in a metal sheet, the fixing member 3 being configured to be fixed to the target to be sensed, particularly to the busbar of a motor, and the retaining member 5 being used to hold the temperature sensor 200, the retaining member including two retaining sections 11a, 11b. In step B, the metal sheet is stamped such that a portion of the fixing member 3 is integrally formed with at least a portion of the retaining member 5.

[0086] The method further includes step C: bending the stamped metal sheet such that the retaining member 3 is configured to receive and secure the temperature sensor 200 along the insertion directions I1, I2. Figure 5 The diagram illustrates a method for manufacturing a sensor assembly 100 according to a sixth embodiment.

[0087] According to step A, provide a fixing bracket 1.

[0088] According to step B, the temperature sensor 200 is received in the holding sections 11a, 11b of the fixed bracket 1. Specifically, the temperature sensor 200 is manually inserted along the insertion directions I1, I2 into the groove 19 formed by the holding sections 11a, 11b of the holding member 5 of the fixed bracket 1 until it abuts against the stop 21 and until the protrusion 211 is received in the recess 27.

[0089] In step C, the temperature sensor 200 is further fixed in the holding sections 11a and 11b by pressing the crimping part 25 of the fixing bracket 1 onto the temperature sensor 200.

[0090] exist Figure 6 and Figure 7 The image shows a method for securing a sensor assembly 100 to a busbar according to a seventh embodiment.

[0091] The method of the seventh embodiment includes step A, in which the plane A1 of the fixing member 3 is arranged to contact the plane A2 of the busbar B1. The busbar B1 may be, for example, a busbar of the stator of a motor. Specifically, the fixing member 3 may be arranged to contact the busbar B1 at the connection position between the busbar B1 and the inverter busbar B2 of the motor.

[0092] According to step B of the method of the seventh embodiment, the fastener F1 (e.g., a bolt) passes through the through hole 7 in the fixing member 3. Specifically, the fastener F1 passes through the through hole T2 in the inverter busbar B2, through the through hole T1 in the motor busbar B1, and through the through hole 7 in the fixing member 3.

[0093] According to step C of the method of the seventh embodiment, the fastener F1 is fastened to the fastening mating part F2. Here, the fastening mating part F2 is a rubber block including a nut N, which has internal threads to allow threaded fastening with the fastener F1.
