[0033] In the current technology, the AMT transmission shift actuator controller is provided with an independent housing, which has the problems of low integration, complex layout, heavy weight, high cost and poor heat dissipation. For example, the current technology provides a hybrid electric drive system and a hybrid vehicle, which includes a housing assembly, a motor assembly, a speed change mechanism assembly and a controller assembly. The controller assembly is also mounted on the housing, and the housing of the controller assembly is connected to the housing assembly to shorten the distance between the controller assembly and the motor. However, the structure has many parts and low integration, which is not conducive to cost control. The current technology also provides a TCU integrated gearbox, a two-speed electric drive system and a vehicle including the two. The TCU integrated gearbox includes an electric shift mechanism, and the electric shift mechanism is integrated with the TCU module in an integrated structure. The two-speed electric drive system includes a TCU integrated gearbox and an integrated drive motor and an MCU module. However, it only arranges the controller and the actuator together, and does not realize the sharing of the housing, and the integration is low.

[0034] In order to solve the problems of low integration and complex connection arrangement of the shift actuator in the related art, referring to Figures 1 and 2, an embodiment of the present application provides a shift actuator assembly, which includes an upper cover shell 1, a base assembly 8 and a transmission controller assembly 2.

[0035] Among them, the base assembly 8 is connected to the upper cover shell 1, and an inner cavity is formed between the base assembly 8 and the upper cover shell 1. The transmission controller assembly 2 is arranged in the inner cavity, and the transmission controller assembly 2 is used to process the received signal and perform the gear shift control function.

[0036] In some optional embodiments, the upper cover shell 1 of the embodiment of the present application can be set to be hollow, and the inner cavity is the hollow space of the upper cover shell 1. In this way, the inner cavity of the upper cover shell 1 can form a space for accommodating the transmission controller assembly 2 and other key components.

[0037] In some optional embodiments, the base assembly 8 can be connected to the upper cover shell 1 by bolt connection, snap connection or welding. For example, a bolt hole is provided at the joint of the upper cover shell 1 and the base assembly 8, and the two parts are firmly connected by bolts, which can resist large mechanical stress and vibration, and the bolt connection is convenient for disassembly and reassembly, and is convenient for regular maintenance of the inner cavity components or timely replacement of components. Alternatively, a hook can be provided on the inner edge of the upper cover shell 1, and a snap groove is provided on the base assembly 8 accordingly. When installing, it is only necessary to press the upper cover shell 1 into the base, and the snap structure realizes automatic engagement.

[0038] In some optional embodiments, the transmission controller assembly 2 of the embodiment of the present application adopts a modular design of a board structure. For example, the transmission controller assembly 2 can be a multi-layer PCB board structure, which includes a main control chip (such as a microcontroller or a dedicated integrated circuit) for processing received signals and performing shift control functions, as well as input / output interface circuits, sensor interfaces, and communication modules.

[0039] The above-mentioned shift actuator assembly includes an upper cover shell 1, a base assembly 8 and a transmission controller assembly 2. The base assembly 8 is connected to the upper cover shell 1, and an inner cavity is formed between the base assembly 8 and the upper cover shell 1; the transmission controller assembly 2 is arranged in the inner cavity, and the transmission controller assembly 2 is used to process the received signal and perform the shift control function. In this application, by arranging the controller assembly in the upper cover shell 1 of the shift actuator, the AMT transmission shift actuator controller does not need to be provided with an independent shell, the structural design is compact, and the types of parts are few, which can effectively reduce the length of the connecting wire harness in the shift actuator to reduce the complexity of the connection. At the same time, reducing the use of shell materials can achieve the goals of weight reduction and cost reduction, and greatly improve the integration and comprehensive performance of the AMT transmission shift actuator.

[0040] In some embodiments, the inner cavity is provided with a mounting plane that matches with the transmission controller assembly 2, and a surface of the transmission controller assembly 2 facing away from the base assembly 8 is fixed on the mounting plane.

[0041] Among them, the mounting plane can be directly fixed to the inside of the upper cover shell 1 by screws or studs, or, a plurality of reinforcing ribs can be provided on the side of the mounting plane facing the top cover plate of the upper cover shell 1, one end of the reinforcing rib is connected to the mounting plane, and the other end of the reinforcing rib is connected to the inner surface of the top cover plate of the upper cover shell 1. The reinforcing ribs can not only fix the mounting plane in the inner cavity of the upper cover shell 1, but also provide necessary mechanical support to prevent the mounting plane from being deformed under the action of vibration and thermal expansion and contraction, thereby ensuring its long-term stability and durability.

[0042] The mounting plane of the embodiment of the present application may be provided with a plurality of reserved fixing holes for use with screws or buckles so as to firmly fix the transmission controller assembly 2 on the mounting plane. The number and layout of these fixing holes are reasonably allocated according to the size and weight of the controller assembly to ensure a secure fixation.

[0043] In some embodiments, a groove is provided on the mounting plane, and a thermal conductive adhesive 9 is provided in the groove.

[0044] In some optional embodiments, the grooves on the mounting plane are arranged along key heat-generating areas of the transmission controller assembly 2. For example, the grooves on the mounting plane correspond to the locations of high-heat-generating components such as the main processor and power devices in the transmission controller assembly 2.

[0045] In some optional embodiments, in order to maximize the contact area between the thermally conductive adhesive 9 and the transmission controller assembly 2, the grooves can be arranged in multiple parallel arrangements or in a grid layout. Specifically, the grooves on the mounting plane are designed in a rectangular grid shape, and the thermally conductive adhesive 9 is evenly filled in the grid grooves. The grid structure can provide a larger heat dissipation area, so that most of the heating areas of the transmission controller assembly 2 can be fully in contact with the thermally conductive adhesive 9. The thermally conductive adhesive 9 efficiently conducts heat from the transmission controller assembly 2 to the mounting plane, and then can dissipate the heat to the external environment through the heat dissipation ribs or other heat dissipation structures on the upper cover shell 1. At the same time, due to the elastic properties of the thermally conductive adhesive 9, when the vehicle vibrates, it can also absorb impact and protect the transmission controller assembly 2 from mechanical vibrations, thereby improving the stability and reliability of the transmission controller assembly 2.

[0046] In some optional embodiments, the mounting plane is a rectangular plate, the thickness of the rectangular plate is 3 to 5 mm, and the thickness of the groove is 1.5 to 2.5 mm. In this way, the rectangular plate with a thickness of 3 to 5 mm can provide sufficient mechanical strength to prevent bending or deformation when installing the transmission controller assembly 2, and enable the mounting plane to withstand a certain load, maintain the stability of the structure, and avoid damage caused by vibration or impact during operation. Combined with the thickness of the mounting plane, the design of the groove thickness allows the thermal conductive adhesive 9 to be better filled and fitted, providing a larger contact area and promoting effective heat conduction. The appropriate groove thickness also helps to achieve uniform heat distribution and prevent local overheating.

[0047] In this embodiment, by setting a groove for accumulating the thermal conductive adhesive 9 on the mounting plane, the accumulation position and amount of the thermal conductive adhesive 9 can be ensured. The heat-generating surface of the transmission controller assembly 2 is in close contact with the mounting plane through the thermal conductive adhesive 9. The thermal conductive adhesive 9 conducts the heat from the controller to the mounting plane, and then dissipates the heat to the external environment through the heat dissipation ribs or other heat dissipation structures on the upper cover shell 1. In addition to heat dissipation, the thermal conductive adhesive 9 also has a certain shock absorption function. Its soft material properties can effectively absorb vibration and impact during the operation of the transmission, prevent the controller assembly from loosening or damage due to vibration, and improve its service life and reliability.

[0048] In some embodiments, the shift actuator assembly also includes a guard plate assembly 3, which is located on the side of the transmission controller assembly 2 facing the base assembly 8. The guard plate assembly 3 fixes the transmission controller assembly 2 to the upper cover shell 1 through the guard plate fastening bolts 4.

[0049] The guard plate assembly 3 of the embodiment of the present application may include a guard plate body and a guard plate fastening bolt 4. The guard plate body, the transmission controller assembly 2 and the edge of the mounting plane are correspondingly provided with through holes. The guard plate fastening bolt 4 passes through the guard plate body through these through holes and docks with the mounting holes reserved on the transmission controller assembly 2 to form a stable connection structure. Specifically, the fastening bolt is first inserted through the through hole of the guard plate, then penetrates to the reserved hole of the transmission controller assembly 2, and then passes through the through hole of the mounting plane, and finally fixed to the upper cover shell 1. The material of the guard plate fastening bolt 4 can be stainless steel, which has good corrosion resistance and strength, ensuring that it is not easy to loosen during long-term use.

[0050] In some optional embodiments, the guard plate body can be made of aluminum alloy or high-strength plastic material with good strength and corrosion resistance. The shape of the guard plate body is a rectangle or other suitable shape matching the transmission controller assembly 2 to ensure maximum coverage and protection.

[0051] In some optional embodiments, the guard plate assembly 3 also includes a protective pad, which is arranged between the guard plate body and the transmission controller assembly 2. The protective pad is made of silicone or rubber material to increase the cushioning effect and prevent damage caused by vibration or impact.

[0052] In this embodiment, the guard plate assembly 3 fixes the transmission controller assembly 2 on the upper cover housing 1 through the guard plate fastening bolts 4 to ensure that the transmission controller assembly 2 does not move during use. The guard plate assembly 3 has a protective function to prevent the transmission controller assembly 2 from being bumped by other parts during assembly, and the fastening bolts and other connecting parts abut against the guard plate assembly 3, which can reduce the clamping force of the connecting parts on the transmission controller assembly 2 and prevent it from being deformed and damaged.

[0053] In addition, the upper surface of the transmission controller assembly 2 is bonded to the upper housing through the thermal conductive adhesive 9, and the lower surface is pressed by the guard plate assembly 3. The combination of the guard plate assembly 3 and the thermal conductive adhesive 9 effectively improves the thermal management capability, ensuring that the transmission controller can still operate stably in a high temperature environment. The combined structure of the guard plate assembly 3 and the mounting plane makes it easier to maintain and replace the transmission controller assembly 2, without disassembling too many parts, and improves maintenance efficiency.

[0054] In some embodiments, the shift actuator assembly also includes a first wiring harness assembly 5; the first wiring harness assembly 5 is respectively connected to the transmission controller assembly 2, the external sensor and the vehicle controller, and the transmission controller assembly 2 receives the shift actuator external sensor signal through the first wiring harness assembly 5 and transmits it with the vehicle signal.

[0055] In some embodiments, the shift actuator assembly also includes a second wiring harness assembly 7; the base assembly 8 is provided with an internal sensor and a solenoid valve of the shift actuator; the second wiring harness assembly 7 is respectively connected to the transmission controller assembly 2, the internal sensor and the solenoid valve, and the transmission controller assembly 2 receives the signal fed back by the internal sensor through the second wiring harness assembly 7, and after processing the received signal, issues an execution command to the solenoid valve through the second wiring harness assembly 7, and the execution command is used to execute the corresponding shift action.

[0056] In this embodiment, the transmission controller assembly 2 is connected to the first wiring harness assembly 5 and the second wiring harness assembly 7 through a connector to achieve signal transmission. One end of the first wiring harness assembly 5 is connected to the transmission controller assembly 2 through a connector, and the other end of the first wiring harness assembly 5 is fixed to the upper cover housing 1 through a wiring harness connector fastening bolt 6.

[0057] One end of the second wiring harness assembly 7 is connected to the transmission controller assembly 2 via a connector, and the other end of the second wiring harness assembly 7 is connected to the solenoid valve and the internal sensor on the base assembly 8 .

[0058] When the shift actuator assembly is powered on, the transmission controller assembly 2 receives the signal fed back by the internal sensor of the shift actuator through the second harness assembly 7, receives the external sensor signal of the shift actuator through the first harness assembly 5, and transmits it with the vehicle signal. The transmission controller assembly 2 calculates and processes the received signal, issues a command to the solenoid valve on the base assembly 8 through the second harness assembly 7, executes the corresponding shift action, monitors the sensor shift position, and realizes the automatic shift control function.

[0059] In some embodiments, in the shift actuator assembly, the transmission controller assembly 2 , the first wiring harness assembly 5 , and the second wiring harness assembly 7 are stacked in sequence from the upper cover housing 1 to the base assembly 8 .

[0060] In some embodiments, in the shift actuator assembly, the mounting plane, the transmission controller assembly 2, the guard plate assembly 3, the first wiring harness assembly 5 and the second wiring harness assembly 7 are stacked in sequence from the upper cover shell 1 to the base assembly 8.

[0061] In some embodiments, ribs are provided on the outer side of the upper cover shell 1 facing away from the solenoid valve base assembly 8, and the ribs are in a grid-like structure.

[0062] For example, the ribs can be arranged in a grid-like manner, which can maximize the strength and rigidity of the shell without adding too much material. The ribs arranged in a grid-like manner can effectively disperse stress from all directions and enhance the overall rigidity of the structure. The surface of the ribs increases the contact area with the air, which helps to enhance the heat dissipation. At the same time, the ribs of the embodiment of the present application can be coated or coated with a thermally conductive material to improve their heat dissipation performance.

[0063] In this embodiment, the outer side of the top cover plate of the upper cover shell 1 is provided with reinforcement and heat dissipation ribs, so as to ensure the strength and rigidity of the shell and improve the heat dissipation efficiency.

[0064] In some embodiments, the base assembly 8 is provided with an airway opening a, and a cylinder is provided on the side of the base assembly 8 facing away from the upper cover shell 1; when the solenoid valve on the base assembly 8 is powered off, the compressed gas in the cylinder is discharged through the airway opening a, and the gas discharged from the airway opening a passes through the side surface of the transmission controller assembly 2 close to the base assembly 8, and is discharged to the outside of the shift actuator.

[0065] During the operation of the transmission controller assembly 2, the internal components will generate heat, and heat dissipation is one of the key issues in the design and use of the controller. In the integrated layout structure of the present application, the heat of the transmission controller assembly 2 can be dissipated to the external environment through the upper surface thermal conductive glue 9 and then through the upper cover shell 1. A heat dissipation rib structure is also provided on the upper cover shell 1 to achieve rapid heat dissipation.

[0066] At the same time, the present application dissipates heat from the lower surface of the transmission controller assembly 2 by means of gas diversion. Specifically, the base assembly 8 is provided with an airway port a, and the exhaust of the solenoid valve in the base assembly 8 is vertically upward, opposite to the lower surface of the transmission controller assembly 2. During the gear shifting process, the solenoid valve will discharge the compressed gas. After the solenoid valve is energized, the compressed gas enters the cylinder through the solenoid valve, pushing the piston assembly to move and performing the gear shifting action. After the solenoid valve is powered off, the compressed gas in the cylinder is discharged through the exhaust port on the upper side of the solenoid valve, and the gas is discharged to the outside of the shift actuator after passing through the outside of the controller, taking away the heat from the surface of the controller. Through the two methods of thermal conductive glue 9 and gas diversion, the heat dissipation efficiency of the transmission controller assembly 2 is greatly improved, thereby avoiding functional failure caused by overheating of the transmission controller assembly 2.

[0067] The embodiments of the present application have the following beneficial effects:

The assembly has a compact appearance and high integration, and the controller performance is improved through rapid heat dissipation. At the same time, the structure is easy to assemble and has a short production cycle.
