In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more features.

[0028] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application.

[0029] The differential lock is a locking mechanism set in the front axle or rear axle of the vehicle. The differential lock controller can control the locking or unlocking of the differential lock, so that the wheels on the front axle or rear axle rotate at the same speed or at different speeds. The transfer case 400 is a transmission component connected to the front axle and the rear axle. The transfer case 400 controller can distribute the input torque to the front axle and the rear axle in proportion to achieve switching between two-wheel drive, four-wheel drive, low-speed four-wheel drive and other modes.

[0030] However, in the existing technology, the differential lock controller and the transfer case 400 controller are independent controllers, and the two independent controllers need to be installed separately and require their own independent wiring harnesses. The number of wiring harnesses is large, the total length is long, and the installation and fixing process is more complicated.

[0031] In order to solve the technical problem that the differential lock driver and the transfer case 400 controller are independent controllers, which leads to complex installation, the present application embodiment provides a four-wheel drive controller 100, see Figure 1 , Figure 2 , Figure 5 and Fig. 9 The four-wheel drive controller 100 includes a shell 110, a base 120 and an electronic device 130. The shell 110 has a accommodating chamber 111; the base 120 is connected to the shell 110, and the base 120 covers the accommodating chamber 111; the electronic device 130 is arranged in the accommodating chamber 111, and the electronic device 130 includes a micro-control module 131, a drive module 132 and a transfer case control module 133. The micro-control module 131, the second drive module 132 and the transfer case control module 133 are integrated on a circuit board 139, and the drive module 132 and the transfer case control module 133 are electrically connected to the micro-control module 131 respectively; wherein the drive module 132 is configured to be electrically connected to the first differential lock 200 and the second differential lock 300; the transfer case control module 133 is configured to be electrically connected to the transfer case 400.

[0032] Specifically, the drive module 132 is used to electrically connect the front axle and the rear axle differential locks, and control the electric excitation coils in the front axle differential lock and the electric excitation coils in the rear axle differential lock, thereby controlling the locking or unlocking of the differential lock, thereby making the wheels on the same bridge rotate at the same speed or at differential speeds.

[0033] Specifically, the transfer case control module 133 is used to electrically connect to the transfer case shift motor 420 to control the transfer case shift motor 420 to rotate to a specified position to achieve gear switching of the transfer case 400 .

[0034] It can be understood that, in some embodiments, the first differential lock 200 and the second differential lock 300 correspond to the differential lock set on the front axle and the differential lock set on the rear axle respectively; in other embodiments, the first differential lock 200 and the second differential lock 300 correspond to the differential lock set on the rear axle and the differential lock set on the front axle respectively.

[0035] Compared with the current technology in which a differential lock controller and a transfer case 400 controller are provided to electrically connect the differential lock and the control box respectively, the four-wheel drive controller 100 in the above embodiment can be electrically connected to both the differential lock and the transfer case 400, thereby reducing the number of controllers, the number of wiring harnesses used to electrically connect the controllers and the total length of the wiring harnesses, thereby reducing the installation steps of components and further reducing the difficulty of installing and fixing components.

[0036] In some embodiments, see Fig.10 and Fig.12 The driving module 132 includes a first submodule 1321 and a second submodule 1322. The first submodule 1321 is electrically connected to the microcontrol module 131, and the first submodule 1321 is electrically connected to the first differential lock 200; the second submodule 1322 is electrically connected to the microcontrol module 131, and the second submodule 1322 is electrically connected to the second differential lock 300.

[0037] It is understandable that, in some embodiments, the first submodule 1321 is electrically connected to the differential lock provided on the front axle, and the second submodule 1322 is electrically connected to the differential lock provided on the rear axle, that is, the first differential lock 200 is a differential lock provided on the front axle and the second differential lock 300 is a differential lock provided on the rear axle; in other embodiments, the first submodule 1321 is electrically connected to the differential lock provided on the rear axle, and the second submodule 1322 is electrically connected to the differential lock provided on the front axle, that is, the first differential lock 200 is a differential lock provided on the rear axle, and the second differential lock 300 is a differential lock provided on the front axle. The first submodule 1321 and the second submodule 1322 are both integrated in the circuit board 139.

[0038] In the above embodiment, by providing the first submodule 1321 and the second submodule 1322 so that the drive module 132 can be electrically connected to the first differential lock 200 and the second differential lock 300 respectively, the first differential lock 200 and the second differential lock 300 can be controlled differently when the front axle and the rear axle are in different working conditions, so that the vehicle can obtain better passing and escape capabilities under complex working conditions. In addition, the first submodule 1321, the second submodule 1322 and the transfer case control module 133 are integrated into the same circuit board 139, which also reduces the number of controllers, and also reduces the number of wire harnesses and the total length of wire harnesses used to electrically connect the controllers, thereby reducing the installation steps of components, and further reducing the difficulty of installing and fixing components.

[0039] In some embodiments, see Fig.11 and Fig.12 The transfer case control module 133 includes a third submodule 1331 and a fourth submodule 1332. The third submodule 1331 is electrically connected to the microcontrol module 131, and the third submodule 1331 is electrically connected to the transfer case shift motor 420; the fourth submodule 1332 is electrically connected to the microcontrol module 131, and the fourth submodule 1332 is electrically connected to the transfer case clutch 410.

[0040] It can be understood that the third submodule 1331 is used to control the transfer case shift motor 420 to rotate and drive the shift fork to move, so that the transfer case 400 can switch between high gear, low gear and neutral gear to output different torques; the fourth submodule 1332 is used to control the engagement and disengagement of the transfer case clutch 410, so that the transfer case 400 can switch between the two-wheel drive mode and the four-wheel drive mode. The third submodule 1331 and the fourth submodule 1332 are both integrated in the circuit board 139.

[0041] In the above embodiment, the third submodule 1331 and the fourth submodule 1332 are arranged in the transfer case control module 133 to realize the transfer case 400 switching between two-wheel drive, high-speed four-wheel drive, neutral gear and low speed gear, so that the vehicle is in different working modes, so that the vehicle can obtain better passing and escape capabilities under complex working conditions. In addition, the third submodule 1331, the fourth submodule 1332 and the drive module 132 are integrated into the same circuit board 139, which also reduces the number of controllers, and also reduces the number of wire harnesses and the total length of wire harnesses used to electrically connect the controllers, thereby reducing the installation steps of components, and further reducing the difficulty of installing and fixing components.

[0042] In some embodiments, the electronic device 130 further includes an identification module 134 , which is integrated into the circuit board 139 , and is electrically connected to the microcontroller module 131 . The identification module 134 is configured to be electrically connected to a transfer case gear position detection device.

[0043] In some embodiments, the identification module 134 is directly electrically connected to the transfer case gear position detection device; in other embodiments, the identification module 134 is electrically connected to the transfer case gear position detection device through the micro control module 131. Further, in some embodiments, the transfer case gear position detection device is a transfer case 400 gear position sensor.

[0044] It can be understood that the identification module 134 is used to set the position of the shift fork corresponding to the different gears of the transfer case 400, so that the transfer case shift motor 420 can drive the shift fork to move to the position corresponding to the specified gear, and the transfer gear detection device is used to detect the actual position of the shift fork.

[0045] In the above embodiment, by integrating the identification module 134 into the circuit board 139 where the microcontroller module 131, the drive module 132 and the transfer case control module 133 are located, the four-wheel drive controller 100 has more functions and a higher degree of integration. In addition, the number of controllers is reduced, and the number and total length of wire harnesses for electrically connecting the controllers are also reduced, thereby reducing the steps for installing components, thereby reducing the difficulty of installing and fixing components.

[0046] In some embodiments, the electronic device 130 further includes a self-test module 135 . The self-test module 135 is integrated into the circuit board 139 , and the self-test module 135 is electrically connected to the micro-control module 131 .

[0047] In some embodiments, the self-test module 135 is configured to detect whether the transfer case 400 is functioning properly.

[0048] In the above embodiment, the self-test module 135 is provided so that the four-wheel drive controller 100 has a transfer case 400 self-test function, so that the four-wheel drive controller 100 has more functions, and it is also avoided to additionally set up a controller with a self-test function, thereby reducing the number of controllers, and also reducing the number of wiring harnesses and the total degree of wiring harnesses used to electrically connect the controllers, thereby reducing the installation steps of components.

[0049] In some embodiments, the electronic device 130 further includes a storage module 136 , which is integrated into the circuit board 139 and electrically connected to the micro-control module 131 .

[0050] It is understandable that the storage module 136 is used to store configuration information, and the micro control module 131 controls the differential locks of the front axle and the rear axle and the transfer case 400 according to the configuration information.

[0051] Compared to the current technology, in which the differential lock controller and the transfer case 400 controller can only receive configuration information input from the outside, the four-wheel drive controller 100 in the above embodiment sets a storage module 136 so that the microcontroller module 131 of the four-wheel drive controller 100 can obtain configuration information both from the outside and only from the inside, thereby further improving the integration and multifunctionality of the four-wheel drive controller 100. In addition, the installation difficulty of the vehicle with the four-wheel drive controller 100 does not increase while having more functions.

[0052] In some embodiments, the electronic device 130 further includes a temperature monitoring module 137 , which is integrated into the circuit board 139 , electrically connected to the microcontroller module 131 , and configured to be electrically connected to a temperature detection device.

[0053] Furthermore, in some embodiments, the temperature detection device includes a temperature sensor. Furthermore, the temperature detection device includes a plurality of temperature sensors, and the plurality of temperature sensors are respectively disposed at one or more of the front axle differential lock, the rear axle differential lock, and the transfer case 400 .

[0054] In the above embodiment, by setting up the temperature monitoring module 137, the temperature of the front axle differential lock, the rear axle differential lock and the transfer case 400 can be detected to determine the working conditions of the front axle differential lock, the rear axle differential lock and the transfer case 400, so that the vehicle with the four-wheel drive controller 100 has better reliability and maintainability.

[0055] In some embodiments, please refer again to Figure 2 Also see Figure 3 and Figure 4 The electronic device 130 also includes a connector 138, which is connected to the circuit board 139. The connector 138 is electrically connected to at least the microcontroller module 131, and the connector 138 is configured to be electrically connected to the wiring harness; the shell 110 has an opening 112 that communicates with the accommodating cavity 111, and the opening 112 is configured to allow the connector 138 to be exposed from the shell 110.

[0056] In some embodiments, the connector 138 is also used to electrically connect to the drive module 132 and the transfer case control module 133 , so that the drive module 132 and the transfer case control module 133 can be directly electrically connected to the differential lock and the transfer case 400 respectively through a wiring harness.

[0057] In the above embodiment, the opening 112 is provided on the housing 110 so that the connector 138 can be connected to the wiring harness, so that the four-wheel drive controller 100 can be electrically connected to the vehicle body controller to exchange data.

[0058] In some embodiments, see Figure 6-Figure 8 The base 120 has at least one through hole 121 , and the through hole 121 is connected to the accommodating cavity 111 .

[0059] It can be understood that, compared with the differential lock controller and transfer case 400 controller in the current technology, the circuit board 139 in the four-wheel drive controller 100 in the above embodiment integrates the drive module 132 and the transfer case control module 133, and the amount of data processing is larger, and more heat is generated. The provision of the through hole 121 can increase the heat exchange efficiency inside and outside the shell 110, thereby avoiding the working efficiency of the four-wheel drive controller 100 being affected by excessive temperature.

[0060] In some embodiments, please refer again to Figure 6-Figure 8The base 120 includes a first connection portion 122, a second connection portion 123, a main body portion 125 and a protrusion 124, the first connection portion 122 is configured to be connectable to the shell 110; the first connection portion 122 and the second connection portion 123 are spaced apart, and the second connection portion 123 is configured to be connectable to the shell 110; the main body portion 125 is connected to and located between the first connection portion 122 and the second connection portion 123; the protrusion 124 is connected to and located between the first connection portion 122 and the second connection portion 123, the protrusion 124 is arranged on one side of the main body portion 125 along a direction perpendicular to the direction from the first connection portion 122 to the second connection portion 123, and the protrusion 124 is protruding along the direction from the circuit board 139 to the base 120 to expand the accommodating cavity 111.

[0061] Specifically, the first connection portion 122 and the second connection portion 123 are respectively connected to a fixing portion 126 , and the fixing portion 126 is used to fix the four-wheel drive controller 100 to the vehicle.

[0062] In some embodiments, please refer again to Figure 5 The four-wheel drive controller 100 further includes a connector 150, which connects the housing 110, the circuit board 139 and the base 120. Specifically, the connector 150 is a threaded connection pair, which penetrates the base 120 and the circuit board 139 and is threadedly connected to the housing 110.

[0063] In the above embodiment, the protrusion 124 is provided to expand the space of the accommodating cavity 111 , thereby increasing air flow to make the heat exchange efficiency higher, thereby improving the reliability of the four-wheel drive controller 100 .

[0064] In some embodiments, please refer again to Figure 6-Figure 8 The protruding portion 124 is spaced apart from the main body portion 125 to form a through hole 121 together with the first connecting portion 122 and the second connecting portion 123 . The through hole 121 is communicated with the accommodating cavity 111 .

[0065] It is understandable that, in some embodiments, the protrusion 124 is made by a stamping process, and the through hole 121 can be used as a stamping process hole to avoid tearing the protrusion 124 or the body 125 during the stamping process of the protrusion 124. In addition, it can be seen from the above that the four-wheel drive controller 100 generates a lot of heat, and the through hole 121 can also be used as a heat dissipation hole to improve the heat exchange efficiency between the inside and outside of the housing 110.

[0066] Furthermore, in some embodiments, since the protrusion 124 is protruded along the direction from the circuit board 139 to the base 120 compared to the main body 125, the through hole 121 achieves an enlarged area due to the protrusion of the protrusion 124. The air can not only flow into and out of the accommodating cavity 111 through the through hole 121 along the direction from the base 120 to the circuit board 139, but also flow into and out of the accommodating cavity 111 along the direction from the main body 125 to the protrusion 124.

[0067] In the above embodiment, by setting the through hole 121, not only the yield rate in the manufacturing process of the base 120 can be improved, and the product damage due to tearing when the protrusion 124 is stamped can be avoided, but also the heat exchange efficiency of the four-wheel drive controller 100 can be improved, and the operating temperature of the four-wheel drive heat exchanger can be reduced, thereby improving the reliability of the four-wheel drive heat exchanger.

[0068] In some embodiments, please refer again to Figure 6-Figure 8 The base 120 includes at least two protrusions 124 , and at least one body portion 125 is disposed between two adjacent protrusions 124 .

[0069] In the above embodiment, at least one main body portion 125 is disposed between two adjacent protrusions 124 so that the four-wheel drive controller 100 has at least two through holes 121 , thereby enabling the four-wheel drive controller 100 to obtain better heat exchange efficiency and reliability.

[0070] Correspondingly, an embodiment of the present application also provides a vehicle, including a differential lock, a transfer case 400 and a four-wheel drive controller 100 as in any one of the above embodiments, the differential lock is electrically connected to the four-wheel drive controller 100, and the transfer case 400 is electrically connected to the four-wheel drive controller 100.

[0071] Furthermore, the four-wheel drive controller 100 is electrically connected to the vehicle body controller to exchange data with the vehicle body controller, and the four-wheel drive controller 100 is connected to the vehicle power supply to obtain power supply.

[0072] In the above embodiment, the vehicle uses a four-wheel drive controller 100 that integrates a microcontroller module 131, a drive module 132 and a transfer case control module 133, which can reduce the installation of one controller and reduce the wiring harness materials used to connect one controller, reduce the difficulty of wiring harness layout, and simplify the vehicle manufacturing steps.

[0073] The above is a detailed introduction to a four-wheel drive controller 100 and a vehicle provided in an embodiment of the present application.
