DETAILED DESCRIPTION

[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention belong to the scope of protection of the present invention.

[0040] The power module is an essential part of the motor controller, which can determine the output current of the motor controller, etc. In order to ensure the working performance of the power module and prevent the power module from being damaged due to overheating, the relevant technology usually sets a temperature sensor on the power module, detects the temperature of the power module through the temperature sensor, and performs over-temperature protection on the power module according to the detected temperature. However, the detection accuracy of the power module temperature in the relevant technology is low.

[0041] Based on this, an embodiment of the present invention provides a power module module, a motor controller of a vehicle and a vehicle, by arranging a detection mounting part on one side of a base of the power module, and arranging a temperature detection part on the side of the power chip of the detection mounting part facing the base, so that the temperature detection part can be elastically abutted against the power chip, thereby realizing direct contact heat transfer between the temperature detection part and the power chip temperature, avoiding heat loss to a certain extent, thereby ensuring the temperature detection accuracy.

[0042] The power module module, the motor controller of the vehicle and the vehicle provided by the present invention are described in detail below with reference to the accompanying drawings through specific embodiments:

[0043] Reference Figures 1 to 6 As shown, this embodiment provides a power module assembly capable of detecting the temperature of a power module 10 .

[0044] Among them, the power module 10 can be applied to the motor controller of the vehicle. The vehicle also includes a motor and a power battery. When in use, the motor controller can convert the electric energy stored in the power battery and provide it to the motor to enable the vehicle to run normally.

[0045] The temperature detection device of the power module 10 includes a base 1 and a detection mounting member 2 .

[0046] Specifically, the power module 10 includes a base 1 and a power chip 31 mounted on one side of the base 1, and the detection mounting member 2 is connected to the side of the base 1 where the power chip 31 is disposed. Figure 5 and Figure 6 For example, the detection mounting member 2 is connected to the substrate 1 along the Figure 5 The lower side in the up-down direction.

[0047] For example, the power chip 31 may be connected to the substrate 1 by laser welding or the like.

[0048] Specifically, a temperature detection component 4 is provided on the side of the detection mounting component 2 facing the power chip 31 , and at least the portion of the detection mounting component 2 corresponding to the temperature detection component 4 is elastic, so that the temperature detection component 4 can elastically abut against the power chip 31 to detect the temperature of the corresponding power chip 31 .

[0049] Exemplarily, the temperature detection element 4 may be a temperature sensor, such as a negative temperature coefficient thermistor (Negative Temperature Coefficient Sensor, NTC for short), a thermocouple, etc., or may be a temperature-sensitive powder, etc.

[0050] Exemplarily, a main control board (not shown in the figure) is provided on the side of the detection mounting member 2 facing away from the base 1, and the main control board can be electrically connected to the temperature detection member 4 and the power chip 31 respectively. For example, when the temperature detected by the temperature detection member 4 exceeds a preset temperature threshold, the output pulse width modulation (PWM) pulse signal of the power chip 31 can be controlled by the main control board to change the current input to the motor and control the heat generation of the power chip 31, thereby ensuring that the power module 10 can operate stably.

[0051] The power module module provided in this embodiment is provided with a detection mounting member 2, which is connected to the side of the base 1 where the power module 10 is provided, and a temperature detection member 4 is provided on the side of the detection mounting member 2 facing the power chip 31, so that at least the portion of the detection mounting member 2 corresponding to the temperature detection member 4 is elastic, so that the temperature detection member 4 can elastically abut against the power chip 31 and detect the temperature of the corresponding power chip 31. Since the temperature detection member 4 can abut against the power chip 31, that is, the two can conduct direct contact heat transfer, compared with the solution of setting the temperature detection member beside the power chip and detecting the radiation temperature of the power chip as the temperature of the power chip, the arrangement of this embodiment can avoid the occurrence of heat loss to a certain extent, thereby improving the temperature detection accuracy to a certain extent, providing a more accurate reference for the subsequent control of the temperature of the power chip 31, facilitating the timely control of the temperature of the power module 10, and then can perform over-temperature protection on the power module 10 to a certain extent, thereby ensuring the safety of the motor controller and the vehicle.

[0052] At the same time, since the temperature detection component 4 is elastically abutted against the power chip 31, it can absorb the assembly tolerance between the substrate 1 and the detection mounting component 2, and thus can ensure the abutment effect of the temperature detection component 4 against the power chip 31 to a certain extent, further ensuring the detection accuracy of the temperature of the power chip 31.

[0053] In addition, the power chip 31 can be TPAK packaged by adjusting the number of power chips 31 and the series-parallel relationship, so that the power module 10 can adapt to different power output requirements and be flexible in use. In other words, the power module 10 provided in this embodiment can not only realize high-precision detection of the temperature of the power chip 31, but also realize customized design of output power, etc., with high flexibility and wide adaptability.

[0054] In some embodiments, reference Figures 2 to 3 As shown, the detection mounting member 2 has a rebound portion 211, and the temperature detection member 4 is arranged on the rebound portion 211. One end of the rebound portion 211 is connected to the detection mounting member 2, and the other end of the rebound portion 211 is a free end to drive the temperature detection member 4 to abut against the corresponding power chip 31.

[0055] In this way, the elastic contact between the temperature detection element 4 and the power chip 31 can be achieved through the rebound effect of the rebound portion 211, thereby ensuring the temperature detection accuracy.

[0056] Of course, in other implementations, at least the position of the detection mounting component 2 corresponding to the temperature detection component 4 may be made of elastic material such as rubber.

[0057] In some embodiments, reference Figure 2 and Figure 3As shown, the detection mounting member 2 is provided with at least a through hole 23 for avoidance, so that while ensuring the temperature detection of the power chip 31, the detection mounting member 2 can also avoid interference with the surrounding parts to a certain extent, thereby ensuring the compactness of the structure of the entire motor controller. Moreover, the provision of the through hole 23 can also play a role in reducing weight to a certain extent.

[0058] In some embodiments, reference Figures 2 to 4 As shown, the detection mounting member 2 is provided with a separation groove 21. The separation groove 21 has two side groove walls 212 arranged opposite to each other along a preset direction, one end of the two side groove walls 212 is connected, and the other ends of the two side groove walls 212 are staggered, and the part of the detection mounting member 2 located in the separation groove 21 forms a rebound portion 211. The preset direction can be, for example, Figure 4 The left and right direction in .

[0059] In other words, the rebound portion 211 can be formed by slotting the detection mounting member 2, so that the rebound portion 211 and the detection mounting member 2 are an integrated structure, and there is no need to connect the rebound portion 211, so that the stability of the rebound portion 211 can be ensured, and then the abutment effect of the temperature detection member 4 and the power chip 31 can be further ensured. Moreover, compared with the solution of connecting the rebound portion to the detection mounting member using elastic members such as springs, this can ensure the elastic abutment between the temperature detection member 4 and the power chip 31, and can also avoid the situation that the installation of the detection mounting member 2 and the substrate 1 is inconvenient due to excessive elastic force to a certain extent.

[0060] In some embodiments, reference Figure 4 As shown, the groove width of the separation groove 21 is smaller than the groove depth of the separation groove 21 .

[0061] Among them, refer to Figure 4 The width of the separation groove 21 can be, for example, Figure 4 The distance in the left and right directions can be Figure 4 In the figure, the depth of the separation groove 21 can be, for example, Figure 4 Groove depth b in the up-down direction.

[0062] In this way, the formed rebound portion 211 is Figure 4 The length in the up-down direction is relatively long, so that the rebound portion 211 has a better rebound effect, thereby further ensuring the abutment effect between the temperature detection component 4 and the power chip 31 .

[0063] In some embodiments, reference Figure 4 As shown, the temperature detection member 4 is disposed near the other end of the rebound portion 211 .

[0064] In this way, the temperature detection element 4 is arranged close to the free end of the rebound part 211, thereby ensuring the rebound force of the rebound part 211 on the temperature detection element 4, and further ensuring good contact between the temperature detection element 4 and the power chip 31 to a certain extent, further improving the temperature detection accuracy.

[0065] In some embodiments, the temperature detection member 4 is bonded to the rebound portion 211. This can ensure the stability of the temperature detection member 4 on the rebound portion 211, thereby ensuring the stability of temperature detection.

[0066] Of course, in other implementations, the temperature detection component 4 may also be fixed on the rebound portion 211 by welding or other methods.

[0067] In some embodiments, reference Figure 4 As shown, the projection of the temperature detection member 4 on the rebound portion 211 is located within the area surrounded by the outer contour of the rebound portion 211. This ensures that the rebound portion 211 stably and reliably supports and rebounds the temperature detection member 4, thereby further ensuring reliable contact between the temperature detection member 4 and the power chip 31.

[0068] In some embodiments, the detection mounting member 2 is detachably connected to the base 1. With this arrangement, when one of the detection mounting member 2 (or the temperature detection member 4 on the detection mounting member 2) and the power module 10 is damaged, only the damaged component needs to be replaced. This can avoid the scrapping of the detection mounting member 2 and the power module 10 as a whole to a certain extent, and especially avoid the scrapping of the higher-cost power chip 31, thereby reducing the cost of maintenance and use.

[0069] In some embodiments, a first mounting hole (not shown in the figure) is provided on the detection mounting member 2, and a second mounting hole (not shown in the figure) is provided on the base 1. The detection mounting member 2 can be connected to the base 1 by fasteners penetrated through the first mounting hole and the second mounting hole.

[0070] In this way, the detection mounting member 2 and the base 1 can be reliably and stably connected, which is beneficial to ensure the abutment effect between the temperature detection member 4 and the power chip 31 and realize reliable detection of the temperature.

[0071] Exemplarily, the fasteners may be bolts, screws, etc.

[0072] Of course, in other embodiments, the detection mounting member 2 and the base 1 may also be connected by means of snap fastening or the like.

[0073] In some embodiments, a first positioning portion (not shown in the figure) is provided on the detection mounting member 2, and a second positioning portion (not shown in the figure) is provided on the base 1. The detection mounting member 2 is pre-positioned on the base 1 through the cooperation of the first positioning portion and the second positioning portion.

[0074] This arrangement can achieve pre-positioning of the detection mounting member 2 and the base 1, thereby facilitating the subsequent connection of the detection mounting member 2 and the base 1, and further improving the assembly efficiency of the detection mounting member 2 and the base 1.

[0075] Exemplarily, for example, when the first positioning portion and the second positioning portion cooperate, the first mounting hole and the second mounting hole are aligned.

[0076] The first positioning portion may be, for example, a positioning protrusion, and the second positioning portion may be a positioning hole for the positioning protrusion to extend into. Alternatively, the first positioning portion may be a positioning hole, and the second positioning portion may be a positioning protrusion.

[0077] In some embodiments, reference Figures 5 and 6 As shown, a driving plate 5 is arranged on the side of the temperature detection element 4 facing away from the base body 1 .

[0078] In specific implementation, the driving board 5 and the power chip 31 can be electrically connected, and the current and voltage of the power chip 31 can be controlled and adjusted through the driving board 5 .

[0079] Exemplarily, for example, the driving board 5 may be electrically connected to the main control board.

[0080] In some embodiments, reference Figure 6 As shown, an insulating member 6 is provided between the driving board 5 and the substrate 1 to isolate the driving board 5 from the power chip 31 .

[0081] This can reduce the electromagnetic interference between the drive board 5 and the power chip 31 to a certain extent, ensuring the normal operation of the drive board 5 and the power chip 31. It can also electrically isolate the high and low voltages of the drive board 5 and the power chip 31 to prevent the high voltage of the power chip 31 from affecting the drive circuit on the drive board 5, thereby improving the safety and reliability of the entire motor controller.

[0082] In some embodiments, reference Figure 6 As shown, the insulating member 6 is located between the base body 1 and the detection mounting member 2 .

[0083] Such a configuration can further reduce the electromagnetic interference between the driving board 5 and the power chip 31. Moreover, since the power chip 31 has a higher voltage than the driving board 5, by setting the insulating part 6 between the power chip 31 and the detection mounting part 2, the isolation effect of the insulating part 6 on the high voltage can be further ensured, thereby ensuring the electrical isolation effect between the driving board 5 and the power chip 31.

[0084] In some embodiments, the projection of the power chip 31 on the substrate 1 is located within a region enclosed by an outer contour of the projection of the insulating member 6 on the substrate 1 .

[0085] In this way, the insulating member 6 can further ensure the electromagnetic interference protection effect and high and low voltage isolation effect on the power chip 31 and the driving board 5 .

[0086] In some embodiments, reference Figures 1 to 6 As shown, there are at least two power chips 31 , and at least two temperature detection components 4 are disposed on the detection mounting component 2 . The at least two temperature detection components 4 are used to correspond to different power chips 31 .

[0087] With this arrangement, the temperatures of at least two different power chips 31 can be detected, which is beneficial to further ensure the working safety and working efficiency of the entire power module 10, and further ensure the safety of the motor controller and the vehicle.

[0088] Specifically, when at least two temperature detection members 4 are provided on the detection mounting member 2, the temperature detection members 4 are elastically abutted against the power chip 31, thereby absorbing the assembly tolerance between the substrate 1 and the detection mounting member 2, so as to ensure that each temperature detection member 4 can reliably maintain abutment with the corresponding power chip 31, thereby improving the temperature detection accuracy. In particular, when the temperature detection member 4 is bonded to the rebound portion 211, and the thickness of the adhesive between each temperature detection member 4 and the corresponding rebound portion 211 is different, resulting in an assembly tolerance between the substrate 1 and the detection mounting member 2, the temperature detection member 4 is elastically abutted against the power chip 31, thereby ensuring the abutment effect between each temperature detection member 4 and the corresponding power chip 31.

[0089] For example, refer to Figure 1 As shown, for example, three power module groups 3 arranged along the left-right direction can be set on the base 1, wherein the power module group 3 on the left includes four power chips 31, the middle power module 10 includes six power chips 31, and the power module 10 on the right includes twelve power chips 31. In specific implementation, the temperature detection component 4 can be set at the corresponding power chip 31 according to the actual temperature detection requirements.

[0090] For example, the corresponding Figure 1 Temperature detection components 4 are respectively arranged at the four power chips 31 of the power module group 3 on the left side of the middle, and the corresponding temperature detection components 4 are arranged at the corresponding temperature detection components 2. Figure 1 Temperature detection components 4 are respectively arranged at three power chips 31 of the power module group 3 in the middle position, and the corresponding temperature detection components 2 are arranged at the corresponding temperature detection components 2. Figure 1 Temperature detection components 4 are respectively provided at three power chips 31 of the power module group 3 on the middle right side.

[0091] In some embodiments, reference Figure 2 As shown, a temperature adapter 22 is provided on the detection mounting member 2 , and all temperature detection members 4 are electrically connected to the driving board 5 through the temperature adapter 22 .

[0092] With such an arrangement, at least two temperature detection components 4 can be first integrated on the temperature adapter 22, and then connected to the drive board 5 through the temperature adapter 22 to transmit the detection results of the corresponding temperature detection components 4 to the drive board 5, thereby simplifying the connection between the corresponding temperature detection components 4 and the drive board 5.

[0093] Exemplarily, a signal line may be provided in the detection installation component 2 , so that the signal pin of the temperature detection component 4 is electrically connected to the temperature adapter 22 through the signal line.

[0094] The temperature adapter 22 may be, for example, a transfer PIN pin, and a transfer male plug that matches and plugs with the transfer PIN pin may be provided on the driving board 5. Alternatively, the temperature adapter 22 may be provided as a transfer male plug, and a transfer PIN pin may be provided on the driving board 5.

[0095] In some embodiments, reference Figure 1 and Figure 3 The substrate 1 has at least two mounting areas 101 for mounting power chips 31, and each mounting area 101 has at least two power chips 31. The detection mounting member 2 has at least two temperature detection members 4 at positions corresponding to each mounting area 101. There are at least two temperature adapters 22, which correspond to each mounting area 101 one by one, so that the temperature detection member 4 in the corresponding mounting area 101 is electrically connected to the driving board 5 through each temperature adapter 22.

[0096] In this way, the temperature detection components 4 on the power chip 31 in the corresponding installation area 101 can be zoned and integrated through each temperature adapter 22. Compared with the solution of using only one temperature adapter and connecting the temperature adapter and the temperature detection component through a signal line, this is conducive to simplifying the electrical connection path between each temperature detection component 4 and the corresponding temperature adapter 22, thereby improving the integration efficiency.

[0097] For example, refer to Figure 1 and Figure 3 For example, the substrate 1 may have Figure 3 Two installation areas 101 are arranged in the vertical direction. Figure 2 Two temperature adapters 22 may be provided on the detection mounting member 2, for example, Figure 3 Each temperature detection element 4 on the upper side is connected to one of the temperature transfer elements 22, and the temperature detection element 4 on the upper side is connected to one of the temperature transfer elements 22. Figure 3 Each temperature detecting element 4 on the lower side is connected to another one of the temperature adapting elements 22 .
