[0030] The powertrain testing device provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0031] In existing technologies, three load motors are typically used to test range-extended power systems. The range-extended power system includes a range extender (i.e., a generator) and a drive motor. The range extender is primarily used for power generation. Two load motors are positioned on either side of the drive motor, and the remaining load motor is positioned on one side of the range extender. When testing the drive motor, the two load motors on either side are connected to the drive motor, outputting power to test its performance parameters. When testing the range extender, the load motor on one side is connected to the range extender, outputting power to test its performance parameters. Because existing technologies require three load motors to test the range-extended power system, the overall space occupied by the EOL test bench is large. Furthermore, when testing the drive motor, the load motor on the range extender side is not used, resulting in low utilization of the load motors.

[0032] Optionally, such as Figures 1 to 5 As shown in the embodiment of this application, a powertrain testing device is proposed, including: a first driving member 11 and a first sliding assembly 21; the first sliding assembly 21 has a test area on one side along a first direction, the test area being used to place a powertrain 30; the first driving member 11 is movably connected to the first sliding assembly 21, and the first driving member 11 can move relative to the first sliding assembly 21 along the first direction and along a second direction, so that the first driving member 11 is connected to the drive motor 32 or generator 31 in the powertrain 30, wherein the second direction is perpendicular to the first direction.

[0033] In this embodiment, a test area is provided on one side of the first sliding assembly 21 along a first direction, and the powertrain 30 is placed in the test area. A first driving member 11 is movably connected to the first sliding assembly 21. The first driving member 11 can move relative to the first sliding assembly 21 along the first direction and along a second direction, so that the first driving member 11 can connect to the drive motor 32 or the generator 31 in the powertrain 30. Thus, the first driving member 11 can move along the first direction X or along the second direction Y via the first sliding assembly 21, allowing it to connect to both the drive motor 32 and the generator 31. Compared to the traditional arrangement requiring three load motors 111, this application reduces the number of load motors 111, thereby reducing the space occupied by the load motors 111. This is beneficial for reducing the space occupied by the powertrain testing device and for the arrangement of other structures within the powertrain testing device. Furthermore, compared to the prior art, the first driving member 11 of this application can participate in the testing of both the drive motor 32 and the generator 31, improving the utilization rate of the first driving member 11.

[0034] It should be noted that, as Figure 1 As shown, the first direction X is the direction of the X-axis, the second direction Y is the direction of the Y-axis, and the third direction Z is the direction of the Z-axis.

[0035] It should be noted that the powertrain testing device also includes a second drive component 12. The second drive component 12 is located on the side of the first drive component 11 away from the test area along the first direction X. The second drive component 12 and the first drive component 11 work together to test the drive motor 32 in the powertrain 30.

[0036] In some embodiments, the powertrain testing device further includes a base 70, on which a first sliding component 21 is disposed. The base 70 is used to provide an installation position for the first sliding component 21. Alternatively, the first sliding component 21 may also be disposed on the ground. Those skilled in the art can choose according to actual needs, and the embodiments of this application are not limited herein.

[0037] Optionally, such as Figure 2 As shown, the first sliding component 21 includes a first slide rail 211 and a second slide rail 212; the second slide rail 212 is slidably connected to the first slide rail 211 along the first direction X, and the first driving member 11 is slidably connected to the second slide rail 212 along the second direction Y.

[0038] In this embodiment, the second slide rail 212 is slidably connected to the first slide rail 211 along the first direction X, and the first drive member 11 is slidably connected to the second slide rail 212 along the second direction Y. This allows the first drive member 11 to move along the first slide rail 211 along the first direction X, facilitating cooperation with the second drive member 12 to test the powertrain 30. Furthermore, the first drive member 11 can be precisely adjusted in position along the second direction Y via the second slide rail 212, ensuring accurate connection between the first drive member 11 and the generator 31 in the powertrain. In other words, this application enables the first drive member 11 to simultaneously support the testing of both the drive motor 32 and the generator 31, further enhancing the versatility of the testing device and meeting more testing needs.

[0039] In some embodiments, the first sliding component 21 includes a first slider and a second slider. The first slider is slidably connected to a first slide rail 211, the second slide rail 212 is fixedly connected to the first slider, the second slider is slidably connected to the second slide rail 212, and the first driving member 11 is fixedly connected to the second slider. In addition, the second sliding component 22 can also be configured as a slider and a groove. For example, a first groove extending along a first direction X and a second groove extending along a second direction Y are provided on the base 70. The slider is slidably connected to the first groove or the second groove, and the first driving member 11 is fixedly connected to the slider. The slider can slide in the first groove or the second groove.

[0040] Optionally, such as Figure 2 As shown, the powertrain testing device also includes a second sliding component 22 and a second driving component 12; the second sliding component 22 and the first sliding component 21 are spaced apart along a first direction, and the test area is located between the first sliding component 21 and the second sliding component 22; the second driving component 12 is movably connected to the second sliding component 22, and the second driving component 12 can move relative to the second sliding component 22 along the first direction so that the second driving component 12 is connected to the drive motor 32 in the powertrain 30.

[0041] In this embodiment, the test area is located between the first sliding component 21 and the first sliding component 21, with the second sliding component 22 and the first sliding component 21 spaced apart along a first direction. The second driving member 12 is movably connected to the second sliding component 22 and can move relative to the second sliding component 22 along the first direction, thereby connecting the second driving member 12 to the drive motor 32 in the powertrain 30. This allows the second driving member 12 to move along the first direction X via the second sliding component 22, connecting to the drive motor 32, and thus cooperating with the first driving member 11 to test the drive motor 32 in the powertrain 30.

[0042] In some embodiments, the second sliding component 22 includes a third slide rail and a third slider, the second drive member 12 is fixedly connected to the third slider, and the third slider is slidably connected to the third slide rail.

[0043] In some embodiments, such as Figure 2 As shown, the powertrain testing device also includes two drive shafts 13, one of which is connected to the first drive member 11, and the other drive shaft 13 is connected to the second drive member 12. This allows the first drive member 11 and the second drive member 12 to be connected to the powertrain 30 via their respective drive shafts 13.

[0044] It should be noted that the first driving component 11 and the second driving component 12 can be driving components of various driving forms such as hydraulic drive, pneumatic drive and electric drive. Those skilled in the art can choose according to actual needs, and the embodiments of this application are not limited here.

[0045] Optionally, such as Figure 2 As shown, the powertrain testing device also includes a tray 72 and a transmission mechanism 40; the transmission mechanism 40 is mounted on the base 70, and the tray 72 is mounted on the transmission mechanism 40. The transmission mechanism 40 is used to transfer the tray 72 so that the powertrain 30 can be carried by the tray 72 and moved to the testing area.

[0046] In this embodiment, by placing the tray 72 on the transfer mechanism 40, the transfer mechanism 40 moves the powertrain 30 from the tray 72 to the test area. In this way, the transfer mechanism 40 automatically transfers the powertrain 30 to the test area via the tray 72, reducing manual operation, shortening test preparation time, and thus improving overall testing efficiency. Furthermore, the combined design of the tray 72 and the transfer mechanism 40 achieves automated transfer of the powertrain 30, reducing the need for manual handling, lowering operational intensity, and improving operational convenience.

[0047] In some embodiments, such as Figure 1 As shown, the powertrain testing device also includes a bracket 71, which is fixed on the base 70, and a transmission mechanism 40 is fixed on the bracket 71. The transmission mechanism 40 can be a belt conveyor, a roller conveyor, or a chain conveyor, etc., and this embodiment of the application is not limited thereto.

[0048] Optionally, such as Figure 2 and Figure 4 As shown, the powertrain testing device also includes a lifting mechanism 50; the lifting mechanism 50 is located on the side of the transmission mechanism 40 away from the tray 72. When the tray 72 is located in the test area, the lifting mechanism 50 is used to drive the tray 72 to move up and down along the third direction Z, which is perpendicular to the first direction X and the second direction Y respectively.

[0049] In this embodiment, by placing the lifting mechanism 50 below the transmission mechanism 40, when the tray 72 is located in the test area, the lifting mechanism 50 can move from below the tray 72 towards the tray 72 along the third direction Z. This allows for precise control of the tray 72's height after the lifting mechanism 50 contacts the tray 72, ensuring accurate alignment of the powertrain 30 with the first drive member 11 or the second drive member 12 in the third direction Z, reducing connection errors, and improving the accuracy and stability of the test results.

[0050] Furthermore, since different types of powertrains 30 have different heights, the introduction of the lifting mechanism 50 allows the tray 72 to be flexibly adjusted in the third direction Z, enabling the first drive member 11 and the second drive member 12 to connect with powertrains 30 at different heights, thereby enhancing the versatility of the testing device.

[0051] In some embodiments, the lifting mechanism 50 may include a pneumatic lifting mechanism, a hydraulic cylinder lifting mechanism, and a screw lifting mechanism, etc., and the embodiments of this application are not limited herein.

[0052] Optionally, such as Figure 2 and Figure 3 As shown, the powertrain testing device also includes a support plate 61 and a clamping member 62; the support plate 61 is disposed on the base 70, and the clamping member 62 is disposed on the support plate 61. The clamping member 62 is located above the transmission mechanism 40. When the lifting mechanism 50 drives the tray 72 to move up and down along the third direction Z to the preset position, the clamping member 62 is used to clamp and fix the powertrain 30 in the tray 72.

[0053] In this embodiment, by placing the clamping member 62 on the support plate 61 and positioning it above the transmission mechanism 40, the clamping member 62 clamps and secures the power assembly 30 within the tray 72 when the lifting mechanism 50 moves the tray 72 along the third direction Z to a preset position. This ensures that after the lifting mechanism 50 moves the tray 72 to a certain height, the clamping member 62 can stably secure the power assembly 30, preventing the first drive member 11 and the second drive member 12 from shifting or vibrating during connection with the power assembly 30, thus improving connection stability. Furthermore, the clamping member 62 can also clamp and secure the power assembly 30 during testing to improve testing stability and accuracy.

[0054] It should be noted that the preset position refers to the tray 72 being at a certain height along the third direction Z, which allows the first drive member 11 and the second drive member 12 to be aligned with the interface corresponding to the powertrain 30 in the third direction Z.

[0055] In some embodiments, the powertrain testing device further includes a movable member 63; the movable member 63 is disposed on the base 70, and the support plate 61 is fixedly connected to the movable member 63; the movable member 63 can drive the support plate 61 to move arbitrarily in the plane containing the first direction X and the second direction Y, so as to connect and fix the clamping member 62 to the powertrain 30.

[0056] Optionally, such as Figure 2 and Figure 4 As shown, the powertrain testing device also includes a sensor 73; the sensor 73 is used to detect whether the powertrain 30 has reached the test area.

[0057] In this embodiment, the sensor 73 is electrically connected to the controller 76. Thus, when the sensor 73 detects that the powertrain 30 has arrived at the test area, the sensor 73 sends a signal to the controller 76, and the controller 76 controls the transmission mechanism 40 to stop operating.

[0058] In some embodiments, the sensing element 73 may be configured as a camera, sensor or other components, and this application embodiment does not impose any limitations.

[0059] In some embodiments, the sensing element 73 may be disposed on the base 70 or on the ground; the embodiments of this application are not limited thereto.

[0061] In this embodiment, by placing a first sensor at the output terminal of the first drive unit 11, and electrically connecting the controller 76 to the first sensor 78, the first sensor collects the first operating parameters at the output terminal. This allows the controller 76 to process and analyze the first operating parameters, generating a detailed test report to help technicians better understand the performance of the first drive unit 11 and provide data support for subsequent improvements.

[0062] In some embodiments, the first sensor 78 may also be disposed on the output end of the second drive unit 12 in order to collect the operating parameters of the second drive unit 12.

[0063] For example, the first sensor 78 can be configured as at least one of an angular acceleration sensor, a torque sensor, a magnetic switch position sensor, and a vibration sensor. The first sensor 78 is used to detect first operating parameters such as angular acceleration, output torque, magnetic switch position, and vibration at the output end. Of course, the first sensor 78 can also be configured as other types of sensors, and this embodiment of the application does not impose any limitations on this.

[0064] In some embodiments, such as Figure 1 As shown, the powertrain testing device also includes a display 77; the controller 76 is connected to the display 77, which is used to display first operating parameter information such as angular acceleration, output torque, magnetic switch position, and vibration.

[0065] Optionally, the powertrain testing device further includes a second sensor 75; the second sensor 75 is electrically connected to the controller 76, and the second sensor 75 is used to collect the second operating parameters of the powertrain 30.

[0066] In this embodiment, by electrically connecting the second sensor 75 to the controller 76, the second sensor 75 collects the second operating parameters of the powertrain 30. This allows the controller 76 to process and analyze the second operating parameters of the powertrain 30 collected by the second sensor 75, helping operators to understand changes during the testing process in real time and ensuring the smooth progress of the test. The second operating parameters include noise parameters, vibration parameters, and acoustic roughness parameters, etc.

[0067] In some embodiments, there are multiple second sensors 75, and the multiple second sensors 75 are electrically connected to the controller 76. The controller 76 is equipped with a noise, vibration, and harshness (NVH) testing system. The NVH testing system in the controller 76 is used to process and analyze the second operating parameters collected by the second sensors 75.

[0068] Optionally, such as Figure 1 , Figure 2 and Figure 5 As shown, it also includes a protective cover 74; the base 70 is provided with a protective cover 74, and the protective cover 74 and the base 70 enclose a receiving cavity. The first driving member 11, the second driving member 12, the first sliding component 21 and the second sliding component 22 are all provided in the receiving cavity, and the second sensor 75 is provided on the cavity wall of the receiving cavity.

[0069] In this embodiment, a protective cover 74 is placed on the base 70, and the protective cover 74 and the base 70 together form a receiving cavity. The first driving member 11, the second driving member 12, the first sliding assembly 21, and the second sliding assembly 22 are all disposed in the receiving cavity, and the second sensor 75 is disposed on the cavity wall. This allows the protective cover 74 to protect the first driving member 11, the second driving member 12, the first sliding assembly 21, and the second sliding assembly 22, preventing damage to these components.

[0070] Optionally, the powertrain testing device also includes a telescopic mechanism 100; the telescopic mechanism 100 is disposed on the cavity wall of the receiving cavity, the second sensor 75 is connected to the telescopic mechanism 100, and the telescopic mechanism 100 can be telescopically moved to adjust the position of the second sensor 75.

[0071] In this embodiment, by placing the telescopic mechanism 100 on the cavity wall of the receiving cavity, the second sensor 75 is connected to the telescopic mechanism 100, and the telescopic mechanism 100 can extend and retract to adjust the position of the second sensor 75. This allows the second sensor 75 to flexibly adjust its position according to testing requirements, adapting to different testing scenarios and the size or layout of the powertrain 30, further improving the flexibility and adaptability of the powertrain testing device. Furthermore, the telescopic mechanism 100 can precisely adjust the position of the second sensor 75, ensuring that the distance or angle between the second sensor 75 and the powertrain 30 reaches the optimal state, thereby improving the accuracy and precision of the test data.

[0072] In some embodiments, the powertrain testing device further includes a support frame disposed in a protective cover 74, and a telescopic mechanism 100 disposed on the support frame.

In this way, the water supply mechanism 80 can provide a stable cooling medium to the cooling channel of the powertrain 30, maintaining the normal operating temperature of the powertrain 30 during testing, avoiding test data deviations or equipment damage due to overheating, thereby improving the accuracy and reliability of the test results.
