Description

Technical Field

[0001] The utility model relates to the technical field of automotive parts, and particularly relates to an electric side step drive assembly. In addition, the utility model also relates to a vehicle. Background Technique

[0002] With the continuous improvement of the automobile production level and the need for efficient and convenient travel modes of people, electric side steps have begun to lead a new fashion of travel with their outstanding features such as intelligence, convenience, and practicality. Most of the existing electric side step products adopt an automatic telescopic design, which can be gracefully unfolded with the opening of the car door without manual operation, making getting on and off the car instantly easy and comfortable. It is precisely due to the above-mentioned prominent practical and fashionable features of the electric side step that the electric side step has gradually become an essential configuration for high-chassis vehicles such as SUVs.

[0003] An electric side step generally consists of several parts such as a drive motor, a control system, a linkage mechanism, and a pedal body. The control system controls the operation of the drive motor by receiving and identifying the door state and other signals of the whole vehicle, and the drive motor drives the linkage mechanism to automatically control the unfolding and retracting actions of the pedal body.

[0004] At present, there are two most common layout schemes for the drive motor and the control system: The first is to integrate the control program and related parameters of the control system into the vehicle controller, and the drive motor is arranged on the linkage mechanism; the second is to install an electric side step for a vehicle that was not originally equipped with a side step, which requires a separate ECU (Electronic Control Unit) to be configured for the controller system of the electric side step, and at the same time, a drive motor is configured on the linkage mechanism.

[0005] It can be seen that both methods need to consider the layout problems of three components: the controller, the vehicle wiring harness, and the motor, and the vehicle needs to reserve space. The first method of integrating the controller into the vehicle controller is not friendly to the selected models of electric side steps. For those who do not choose the electric side step configuration, the control configuration part of the electric side step cannot be flexibly removed, and the cost cannot be saved. Moreover, both schemes require the separate development of the controller, and need to be matched and debugged with the motor, with a long assembly and speed regulation cycle and high overall development costs. Summary of the Utility Model

[0039] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0040] Embodiment 1

[0041] This embodiment relates to an electric side step drive assembly, and provides an electric side step drive assembly integrated with a control unit; an exemplary structure thereof is as Figure 1 and Figure 2 shown.

[0042] Overall, the electric side step drive assembly includes a motor body 1, a front end cover assembly 2 and a rear end cover assembly 3 respectively provided at the front and rear ends of the motor body 1, and a motor controller provided in the rear end cover assembly 3. Among them, the control circuit 400 of the motor controller is connected to the motor circuit 100 of the motor body 1, and a port for connecting the motor controller and the vehicle controller is provided on the rear end cover assembly 3.

[0043] It should be noted that based on the above overall design concept, the technical solution of the present utility model can adopt a variety of different specific implementation structures, forms or configuration sequences. For example, the connection between the above control circuit 400 and the motor circuit 100 can adopt a direct connection method of the circuit or be connected through a connector, and it can be set based on the principle of realizing the power supply between the motor controller and the motor and the input and output of control signals; the specific setting sequence, installation method, etc. between the front end cover assembly 2, the rear end cover assembly 3 and the motor body 1 can also be flexibly adjusted. For the parts required for the implementation of the overall solution but not involved in the above overall setting, reasonable and flexible design can be carried out with reference to the mature setting means in the art, the actual situation during implementation, etc. The following specific implementation solutions of this embodiment are only one of the relatively optimal ones among the many solutions that can be formed by the above various combinations and their variations. In actual implementation, those skilled in the art can make flexible adjustments and improvements in combination with the actual situation. Obviously, the many solutions that can be formed by the above various combinations of specific forms and their variations, as well as the specific implementation solutions of this embodiment, are all within the protection scope of the present utility model.

[0044] Specifically, in combination with Figure 3 、 Figure 4 and Figure 5 shown, a reduction mechanism 20 is provided in the front end cover assembly 2 of this embodiment. The power of the motor body 1 is transmitted to the power output shaft 200 through the reduction mechanism 20; and then the link mechanism of the electric side step is driven to move, so as to drive the electric side step to unfold or retract. Integrating the reduction mechanism 20 in the front end cover assembly 2 of the motor body 1 can further optimize the overall structure of the drive assembly and improve the power output performance of the motor body 1, achieving the purpose of reducing the output speed and increasing the output torque.

[0045] Based on the situation that a motor controller is provided in the rear end cover assembly 3, after the motor circuit 100 of this embodiment is led out from the motor body 1, it is led out from the front end cover assembly 2 to the outside of the motor body 1. At the same time, the control circuit 400 is led out from the rear end cover assembly 3, and then the motor circuit 100 and the control circuit 400 are plugged and connected through a connector. Preferably, both the motor circuit 100 and the control circuit 400 are arranged above the motor body 1, and then the motor-side connector 10 at the end of the motor circuit 100 and the controller-side connector 40 at the end of the control circuit 400 are plugged and fixed on the top of the motor body 1 after being plugged. Leading out the motor circuit 100 of the motor body 1 from one end of the front end cover assembly 2 and using a connector to quickly plug and connect the control circuit 400 of the motor controller and the motor circuit 100 of the motor body 1 not only makes the overall circuit layout reasonable and efficient, but also can greatly improve the overall assembly efficiency of the electric side step drive assembly.

[0046] As Figure 5As shown, a wire passing hole 303 for leading out the control circuit 400 is provided on the housing of the rear end cover assembly 3 in this embodiment, and a sealing member (not shown in the figure) is provided in the wire passing hole 303. By providing the wire passing hole 303 on the housing of the rear end cover assembly 3 and providing a sealing member such as a rubber plug in the wire passing hole 303, the gap between the wire passing hole 303 and the control circuit 400 can be well blocked, thereby improving the sealing effect inside the rear end cover assembly 3, providing a good sealed space for the motor controller, and achieving the effects of waterproofing and dustproofing.

[0047] For the convenience of connecting the motor circuit 100 and the control circuit 400; preferably, the wire passing hole 303 is provided on the housing of the rear end cover assembly 3 facing the front end cover assembly 2, and further, the above-mentioned port is provided on the housing of the rear end cover assembly 3 facing away from the front end cover assembly 2. By respectively arranging the wire passing hole 303 and the port on both sides of the rear end cover assembly 3, the separate arrangement of the incoming and outgoing lines is realized, which can optimize the overall circuit layout of the motor controller and facilitate the overall assembly and daily use and maintenance of the electric side step drive assembly.

[0048] Regarding the setting form of the rear end cover assembly 3, of course, there are many different structural schemes to choose from. In this embodiment, as Figure 5 shown, the rear end cover assembly 3 includes a lower end cover 30 and an upper end cover 31 that are buckled together. Based on the above-mentioned split structure, the motor controller can be fixedly arranged in the inner cavity formed between the lower end cover 30 and the upper end cover 31. In this case, the lower end cover 30 abuts against the rear end of the motor body 1, and the upper end cover 31 is buckled on the side of the lower end cover 30 facing away from the motor body 1. To improve the sealing effect between the lower end cover 30 and the upper end cover 31, it is preferable to sandwich a sealing ring 42 between the buckling end faces of the lower end cover 30 and the upper end cover 31. For this purpose, a sealing groove 300 for arranging the sealing ring 42 can be provided on the end face of the lower end cover 30.

[0049] The rear end cover assembly 3 adopts the form of buckling the split lower end cover 30 and upper end cover 31, which can form a sealed space for accommodating the motor controller between the upper end cover 31 and the lower end cover 30, facilitating the installation and setting of the motor controller in the inner cavity. Based on the setting conditions of the upper end cover 31 and the lower end cover 30, the above-mentioned wire passing hole 303 can be opened on the lower end cover 30, and the port is arranged on the upper end cover 31; in this way, the port is more convenient for connecting with the lines from the vehicle controller.

[0050] For the motor controller, there can be various installation forms. For example, a separate housing can be designed for the motor controller and fixedly installed in the inner cavity of the rear end cover assembly 3; or the control chip and electrical components of the motor controller can be directly arranged on the circuit board, and then the circuit board can be fixedly installed in the inner cavity. In this embodiment, the circuit board solution is adopted for the motor controller. Specifically, the motor controller of this embodiment includes a PCB board 4 provided on the lower end cover 30. At the same time, an installation seat 304 is provided in the inner cavity on one side of the lower end cover 30, and the PCB board 4 is screwed to the installation seat 304 through a fastener 6.

[0051] The motor controller adopts the architecture form of the PCB board 4, which is convenient for arranging and soldering various chips and electronic components on the PCB board 4. At the same time, as the substrate of the motor controller, the PCB board 4 can be well fixed and installed on the lower end cover 30 or the upper end cover 31. The part of the above-mentioned inner cavity on the lower end cover 30 is in the form of a sunk groove. Based on this form, a plurality of installation seats 304 are arranged in the inner cavity (i.e., the sunk groove) on one side of the lower end cover 30. By using the screw holes on the installation seat 304 and the matching fasteners 6, the PCB board 4 can be well fixed in the inner cavity in a suspended manner, ensuring the insulation between the PCB board 4 and the rear end cover assembly 3.

[0052] It should be noted that the fixation between the lower end cover 30 and the upper end cover 31, the fixation of the PCB board 4 on the lower end cover 30, and the fixation between the rear end cover assembly 3, the front end cover assembly 2 and the motor body 1 can adopt various methods, such as snap connection, bolt connection, etc. In this embodiment, the above three fixations respectively adopt three specifications of fasteners 6. Specifically, five first fastening screws 601 are used to screw and fix the lower end cover 30 and the upper end cover 31; the PCB board 4 is screwed to the corresponding five installation seats 304 through five second fastening screws 602. Two long-sized third fastening screws 603 are passed through between the rear end cover assembly 3 and the front end cover assembly 2. A connecting ear 301 is provided on each side of the lower end cover 30, and an installation hole 302 is provided on the connecting ear 301. After the third fastening screw 603 passes through the installation hole 302 and is screwed to the front end cover assembly 2, the motor body 1 can be clamped between the rear end cover assembly 3 and the front end cover assembly 2, realizing the integral fixation of the motor body 1, the front end cover assembly 2 and the rear end cover assembly 3.

[0053] In addition, an insertion interface 310 is provided on the upper end cover 31 of this embodiment, and a controller socket 5 extending toward the insertion interface 310 on one side of the upper end cover 31 is provided on the PCB board 4. In this way, the port for connecting the communication line of the vehicle controller can be provided on the controller socket 5.

[0054] An insertion interface 310 is provided on the upper end cover 31. At the same time, a controller socket 5 is provided on the PCB board 4, and the end of the controller socket 5 extends out of the insertion interface 310 to be used as the above-mentioned port, thus providing good conditions for quick insertion and connection between the vehicle controller and the motor controller. To improve the sealing performance at the insertion interface 310, sealing gaskets, sealants and other sealing components can of course be provided at the gap between the insertion interface 310 and the controller socket 5.

[0055] Meanwhile, a heat-conducting gasket 41 can also be provided on the side of the PCB board 4 facing the upper end cover 31, and the heat-conducting gasket 41 is abutted against the upper end cover 31. By providing the heat-conducting gasket 41 between the PCB board 4 and the upper end cover 31, the heat generated on the PCB board 4 can be timely transferred to the rear end cover assembly 3 and then diffused to the outside, which is beneficial to improving the cooling effect of the motor controller, thereby improving the operating stability of the motor controller and the motor body 1.

[0056] In summary, for the electric side step drive assembly of this embodiment, the motor controller for controlling the power output of the motor body 1 is integrally arranged in the rear end cover assembly 3, which not only improves the structural compactness of the electric side step drive assembly, but also the relevant step programs and parameters for controlling the electric side step action can be preset in the motor controller, and the matching and debugging between the motor controller and the motor body 1 can be completed in advance, thus providing an electric side step drive assembly integrated with a control unit.

[0057] Embodiment 2

[0058] This embodiment relates to a vehicle configured with an electric side step, and the electric side step adopts the electric side step drive assembly provided in Embodiment 1.

[0059] The electric side step drive assembly of the present utility model creates a general platform integrating the electric side step drive motor and the controller, which can be shared on multiple vehicle platforms, eliminating the need to consider the separate layout of the controller, reducing the R & D cycle of the controller and the matching and debugging time, cutting down the R & D costs. Moreover, in the integrated scheme of the intelligent motor, the matching degree between the controller and the motor is higher, which can effectively reduce the occurrence of control failure faults.

[0060] The above are only the preferred embodiments of the present utility model. The detailed explanations of the configuration, specific examples of the structural settings, or the descriptions of the assembly and connection methods are all for the need of full disclosure, so that those skilled in the art can better implement the present utility model, rather than to limit the protection scope of the present utility model.
