[0054] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0055] In the present disclosure, unless otherwise specified, directional words such as "up, down, left, right" are generally defined based on the drawing direction of the corresponding drawings, and "inside and outside" refer to the inside and outside of the corresponding component outline.

[0056] Figure 1 is a schematic diagram of a circuit layout of an integrated controller according to an embodiment of the present disclosure, Figure 3 Schematic diagram of the structure of the box in the integrated controller of one embodiment of the present disclosure. Figure 1 and Figure 3As shown, the integrated controller includes a housing 10, a left drive motor controller 300, a right drive motor controller 400, an air compressor motor controller 500, a steering motor controller 600, a DC-DC voltage converter 700, and a high-voltage power distribution module 900. The left drive motor controller 300, the right drive motor controller 400, the air compressor motor controller 500, the steering motor controller 600, the DC-DC voltage converter 700, and the high-voltage power distribution module 900 are all arranged in the housing 10.

[0057] like Figure 1 and Figure 3 As shown, the left drive motor controller 300, the right drive motor controller 400, the air compressor motor controller 500, the steering motor controller 600 and the DC-DC voltage converter 700 are all connected to the high-voltage power distribution module 900. The box 10 is provided with a plurality of input and output interfaces corresponding to the high-voltage power distribution module 900, the left drive motor controller 300, the right drive motor controller 400, the air compressor motor controller 500, the steering motor controller 600 and the DC-DC voltage converter 700.

[0058] Alternatively, if Figure 2 As shown, Figure 2 It is a circuit diagram of the whole vehicle connection of an integrated controller of an embodiment of the present disclosure, wherein the left drive motor controller 300, the right drive motor controller 400, the air compressor motor controller 500, the steering motor controller 600, the DC-DC voltage converter 700, and the high-voltage power distribution module 900 are connected to the BMS (Battery Management System) through the corresponding input and output interfaces on the box 10; the left drive motor controller 300 and the right drive motor controller 400 are connected to the corresponding drive motors and sensors through different input and output interfaces on the box 10; the air compressor motor controller 500 is connected to the air compressor motor and the sensor through the input and output interfaces on the box 10; the steering motor controller 600 is connected to the steering motor and the sensor through the input and output interfaces on the box 10; the DC-DC voltage converter 700 is connected to the low-voltage battery through the input and output interfaces on the box 10.

[0059] It should be noted that the number of sensors connected to the left drive motor controller 300 , the right drive motor controller 400 , the air compressor motor controller 500 or the steering motor controller 600 may be one or more.

[0060] Continue to refer to Figure 2The high-voltage power distribution module 900 can be connected to the corresponding air-conditioning compressor, PTC (Positive Temperature Coefficient) heater, defrost controller, and battery thermal management system compressor through different input and output interfaces on the box 10.

[0061] like Figure 2 As shown, the box body 10 needs to be provided with a battery pack interface 905 and a charging gun interface 906, and the battery pack interface 905 and the charging gun interface 906 are both connected to the high-voltage power distribution module 900. The high-voltage power distribution module 900 needs to be connected to the high-voltage power battery through the battery pack interface 905 so that the high-voltage power battery can supply power to other modules; the charging cabinet needs to be plugged into the charging gun interface 906 through the charging gun to charge the high-voltage power battery.

[0062] In the integrated controller provided by the present disclosure, by integrating the left drive motor controller, the right drive motor controller, the air compressor motor controller, the steering motor controller, the DC-DC voltage converter and the high-voltage power distribution module in the box, the layout space of the whole vehicle can be optimized and the development cost can be reduced; wherein, these modules are integrated in the box, and the modules can be connected by means of a transfer copper bus, which is convenient for detecting which modules are aging and the like compared to the wiring harness connection, and reduces the cost; in addition, it is also convenient to replace the modules in the box, for example, by replacing the modules corresponding to different models, it can be used for dozens of models, realize the platformization of the controller, and solve the technical problems in the related technology that the detection cost is high and the assembly difficulty of the whole vehicle is increased because each controller module in the high-voltage system of the vehicle operates independently and is connected by a wiring harness to realize the operation of the whole vehicle. In addition, by integrating the left drive motor controller and the right drive motor controller, the whole wheel side drive or single motor drive can be realized.

[0063] Please refer to Figure 3 , Figure 4 , Figure 5 and Figure 6 , Figure 4 is a schematic diagram of the circuit layout of the upper box in the integrated controller of one embodiment of the present disclosure, Figure 5 is a schematic diagram of the circuit layout of the lower box in the integrated controller of an embodiment of the present disclosure, Figure 6 FIG. 1 is an exploded schematic diagram of the assembly of the upper box and the lower box in an integrated controller according to an embodiment of the present disclosure. Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the box 10 includes an upper box 100 and a lower box 200; the left drive motor controller 300 and the right drive motor controller 400 are installed in the upper box 100, and the air compressor controller 500, the steering motor controller 600 and the DC-DC voltage converter 700 are installed in the lower box 200; the high-voltage power distribution module 900 is provided in both the upper box 100 and the lower box 200, and the battery pack interface 905 and the charging gun interface 906 are both provided in the upper box 100.

[0064] Optionally, the upper box 100 is provided with at least two battery pack interfaces 905 and two charging gun interfaces 906. In the embodiment given in the accompanying drawings, the number of the battery pack interface 905 and the charging gun interface 906 is two. Since the battery pack interface 905 is dual-channel, single battery pack or dual battery pack operation can be realized; since the charging gun interface 906 is dual-channel, multiple charging modes such as dual DC charging, dual AC charging, AC / DC charging, single-gun DC charging, and single-gun AC charging can be realized.

[0065] like Figure 1 , Figure 2 and Figure 4 As shown, a magnetic ring 903 and a Y capacitor 904 are provided on the connection line between the battery pack interface 905 and the high-voltage power distribution module 900, and on the connection line between the charging gun interface 906 and the high-voltage power distribution module 900. By adopting a magnetic ring plus a Y capacitor design in the charge and discharge input interface, space can be saved and EMC (ElectroMagnetic Compatibility; electromagnetic compatibility) can be improved.

[0066] like Figure 1 , Figure 2 and Figure 4 As shown, the upper box 100 is also provided with a leakage sensor 902 connected to the high-voltage power distribution module 900, and the upper box 100 is provided with an input and output interface corresponding to the leakage sensor 902, and the input and output interface is connected to the BMS. By providing the leakage sensor 902, not only can monitoring protection be provided when the controller in the box 10 leaks, but also a protection function of charging contactor sintering detection is provided.

[0067] like Figure 1 , Figure 2 and Figure 4As shown, the upper box 100 is also provided with an optical coupler sintering detector 901 connected to the high-voltage power distribution module 900, and the upper box 100 is provided with an input and output interface corresponding to the optical coupler sintering detector 901, and the input and output interface is connected to the BMS. By providing the optical coupler sintering detector 901, the sintering detection function of all contactors in the integrated controller can be realized.

[0068] like Figures 6 to 13 As shown, the upper box body 100 is connected to the lower box body 200, and a first cooling water channel and a second cooling water channel independent of each other are arranged between the upper box body 100 and the lower box body 200. The right drive motor controller 400, the air compressor controller 500 and the steering motor controller 600 dissipate heat through the first cooling water channel, and the left drive motor controller 300 and the DC-DC voltage converter 700 dissipate heat through the second cooling water channel.

[0069] In the integrated controller provided by the present disclosure, two independent cooling water channels are set to dissipate heat for different modules on the integrated controller. Compared with the single water channel setting in the prior art, the use of dual water channel cooling has at least the following three advantages: First, when the number of modules to be cooled remains unchanged, the number of modules cooled by the coolant in each water channel can be reduced, which to a certain extent avoids the situation where the cooling effect is lost due to the high temperature of the coolant, and ensures the effective cooling of each module to be cooled; second, the circulation path of each water channel is shortened, which reduces the pressure loss during the flow of the coolant, thereby reducing the requirements for the water pump, that is, allowing the use of a water pump with relatively small pressure and flow. In addition, the shortening of the circulation path can also shorten the time for the high-temperature coolant to circulate inside the integrated controller, avoiding the increase in the temperature of the entire integrated controller; third, the area through which each water channel flows is reduced, and the circulation path is shortened, which reduces the difficulty of sealing the water channel, thereby reducing the risk of water leakage in the water channel.

[0070] The upper box 100 and the lower box 200 may be formed into any appropriate structure and shape. Figure 6 As shown, the upper box body 100 includes an upper box body bottom wall 101 and an upper box body side wall 102 formed around the upper box body bottom wall 101, and a first cooling water groove 103 and a second cooling water groove 104 are formed on the lower surface of the upper box body bottom wall 101, and the lower box body 200 includes a lower box body top wall 201 and a lower box body side wall 202 formed around the lower box body top wall 201. A third cooling water groove 203 and a fourth cooling water groove 204 are formed on the upper surface of the lower box body top wall 201, and the lower surface of the upper box body bottom wall 101 is attached to the upper surface of the lower box body top wall 201, so that the first cooling water groove 103 and the fourth cooling water groove 204 jointly define a first cooling water channel, and the second cooling water groove 104 and the third cooling water groove 203 jointly define a second cooling water channel.

[0071] In this embodiment, the structure of the upper box bottom wall 101 and the lower box top wall 201 is fully utilized, and the first cooling water channel and the second cooling water channel that are independent of each other are defined by opening a water trough on the box bottom wall 101 and the lower box top wall 201, thereby avoiding the need to process cooling water channels separately on the box, saving space, and facilitating the arrangement of other components in the integrated controller. In other alternative embodiments, the first cooling water channel and the second cooling water channel may be separately arranged on the upper box bottom wall 101 or the lower box top wall 201; or, one of the first cooling water channel and the second cooling water channel may be separately formed on the upper box bottom wall 101, and the other may be separately formed on the lower box top wall 201; or, two independent water pipes may be separately arranged, and the two water pipes are fixed to the box of the integrated controller by fasteners, and the interiors of the two water pipes respectively define the first cooling water channel and the second cooling water channel.

[0072] In order to achieve reliable connection between the upper box body 100 and the lower box body 200 and improve the sealing performance of the first cooling water channel and the second cooling water channel, in one embodiment, the upper box body 100 and the lower box body 200 are connected by bolts and friction welding.

[0073] In the present disclosure, the components to be cooled in the left drive motor controller 300 and the right drive motor controller 400 are mainly IGBT (insulated gate bipolar transistor) modules, and the components to be cooled in the air compressor controller 500 and the steering motor controller 600 are IPM (intelligent power module). The IGBT module usually dissipates heat by directly contacting the coolant, and the IPM 501 of the air compressor controller 500 and the IPM 601 of the steering motor controller 600 usually dissipate heat by contacting the wall of the cooling pipe. Therefore, in one embodiment of the present disclosure, during installation, the air compressor controller 500, the steering motor controller 600 and the DC-DC voltage converter 700 can contact the lower box top wall 201, so that when the coolant flows on the lower box top wall 201, the above three modules can exchange heat with the coolant through the lower box top wall 201 to achieve the purpose of heat dissipation and cooling.

[0074] In addition, if Figure 6 , Figure 7 , Fig.11 and Fig.13 As shown, two openings 105 penetrating the bottom wall 101 of the upper box body are formed on the bottom wall 101 of the upper box body, and the left drive motor controller 300 is arranged on one opening 105 so that the heat dissipation column of the left drive motor controller 300 (the heat dissipation column 801 of the IGBT module) contacts the coolant in the second cooling water channel; the right drive motor controller 400 is arranged on the other opening 105 so that the heat dissipation column of the right drive motor controller 400 contacts the coolant in the first cooling water channel.

[0075] Furthermore, if Figure 6 and Figure 7 As shown, a reinforcing rib 106 is formed in the opening 105 , and two ends of the reinforcing rib 106 are connected to a pair of side edges of the opening 105 , and the reinforcing rib 106 is perpendicular to the flow direction of the coolant.

[0076] like Figure 6 and Figure 8 As shown, a boss 205 is formed on the upper surface of the lower box top wall 201 at a position corresponding to the opening 105, the boss 205 is adapted to the shape of the opening 105, and a avoidance groove 206 for avoiding the reinforcing rib 106 is formed on the boss 205. In this way, after the upper box bottom wall 101 and the lower box top wall 201 are attached, the boss 205 is inserted into the opening 105, the reinforcing rib 106 is inserted into the avoidance groove 206, and the upper surface of the reinforcing rib 106 is flush with the upper surface of the boss 205. At this time, the heat dissipation column 801 of the IGBT module is placed on the boss 205, and the coolant flows between the gaps of the multiple heat dissipation columns 801, thereby achieving heat exchange.

[0077] Here, by setting the reinforcing rib 106, on the one hand, the structural strength of the bottom wall 101 of the upper box body can be improved to meet the strength requirements for the installation of components such as the left drive motor controller 300 and the right drive motor controller 400. On the other hand, since the reinforcing rib 106 is perpendicular to the flow direction of the coolant, it plays a role in blocking the lower coolant, thereby increasing the allowable amount of the width dimension of the boss 205 being smaller than the width dimension of the opening 105. In other words, if there is no reinforcing rib 106, in order to avoid the coolant from flowing quickly through the gap between the left and right side walls of the boss 205 and the left and right side walls of the opening 105 and weakening the cooling effect of the coolant on the IGBT module, the width dimension of the boss 205 is usually increased as much as possible to reduce the above-mentioned gap. In the present disclosure, due to the presence of the reinforcing rib 106, even if the width dimension of the boss 205 is much smaller than the width dimension of the opening 105, the coolant will not flow through the gap between the left and right side walls of the boss 205 and the left and right side walls of the opening 105, thereby improving the cooling effect of the coolant on the IGBT module.

[0078] Furthermore, in order to maximize the cooling of the parts to be cooled and improve the cooling efficiency, in one embodiment of the present disclosure, the coolant in the first cooling water channel can first cool the steering motor controller 600, and then cool the air compressor controller 500 and the right drive motor controller 400, that is, the coolant first cools the steering motor controller 600 with a relatively low heat generation, and finally cools the right drive motor controller 400 with a high heat generation. The advantage of this is that the temperature of the coolant will not increase significantly after flowing through the steering motor controller 600, and it can still play an effective cooling role in the process of flowing through the air compressor controller 500 and the right drive motor controller 400. Similarly, the coolant in the second cooling water channel first cools the DC-DC voltage converter 700 with a lower heat generation, and then cools the left drive motor controller 300 with a higher heat generation.

[0079] In the present disclosure, the cross-sectional shape of the first cooling water channel and the second cooling water channel and the position on the case of the integrated controller can be flexibly arranged according to the structure and position of the surrounding components, and the present disclosure does not limit this. In one embodiment, in order to facilitate processing, the cross-sectional shape of the first cooling water channel and the second cooling water channel can be rectangular, and in order to facilitate the arrangement of other components, the first cooling water channel and the second cooling water channel can be symmetrically arranged on the fitting surface between the upper case 100 and the lower case 200.

[0080] It should also be noted that, in the integrated controller provided in the present invention, by integrating the left drive motor controller, the right drive motor controller, the air compressor motor controller, the steering motor controller, the DC-DC voltage converter and the high-voltage power distribution module in the housing, the wearing parts in the high-voltage power distribution module such as the charging fuse, the main fuse, the power distribution small fuse and the pre-charging resistor can be replaced on the whole vehicle, and there is no need to return the integrated controller to the manufacturer for replacement, thereby further saving costs.

[0081] The present disclosure also provides a vehicle, the vehicle comprising the above-mentioned integrated controller. Optionally, the vehicle further comprises a first water pump and a second water pump, the first water pump being used to drive the coolant circulation in the first cooling water channel, and the second water pump being used to drive the coolant circulation in the second cooling water channel. Compared with the method of only setting a single water pump, by setting two independent water pumps, the situation of cooling failure of the integrated controller caused by failure of a single water pump can be avoided, thereby improving the reliability of normal operation of the whole vehicle.

[0082] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0083] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction.

[0084] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
