In this application, the lubrication testing device will be used in automobile manufacturing, and the testing of the electric drive of new energy vehicles will be used as an example to illustrate.

[0026] Please refer to Figure 1 and Figure 2 , Figure 1 It is a schematic diagram of the three-dimensional structure of an embodiment of the lubrication testing device of the present application; Figure 2 This is a schematic diagram of the three-dimensional structure of an embodiment of the lubrication testing device of the present application equipped with a device to be tested.

[0027] In one aspect of the present application, a lubrication testing device 10 is provided. The lubrication testing device 10 is used to test a device to be tested 20. The device to be tested 20 may be an electric drive or the like.

[0028] The lubrication testing device 10 of the present application includes a base 11, a rotating assembly 12, and a locking assembly 13. The base 11 is configured to be mounted on a workbench (not shown); the rotating assembly 12 is configured to support a device to be tested 20; the rotating assembly 12 is connected to the base 11 via the locking assembly 13, such that the rotating assembly 12 is fixed to the base 11 or is rotatable relative to the base 11 in a first direction X; the base 11 can rotate relative to the workbench in a second direction Y, thereby driving the rotating assembly 12, the locking assembly 13, and the device to be tested 20 to rotate in the second direction Y; wherein the plane of the first direction X intersects the plane of the second direction Y.

[0029] As can be seen from the above structure, the base 11 is disposed on the workbench, which can greatly improve the stability of the lubrication testing device 10 when testing the device to be tested 20. The base 11 can also provide a certain support for the rotating assembly 12, and the rotating assembly 12 can also provide a certain support for the device to be tested 20. Therefore, when the rotating assembly 12 is fixedly connected to the base 11 via the locking assembly 13, when the base 11 rotates relative to the workbench in the second direction Y, it can drive the rotating assembly 12, the locking assembly 13, and the device to be tested 20 to rotate in the second direction Y. When the rotating assembly 12 is movably connected to the base 11 via the locking assembly 13, when the rotating assembly 12 rotates relative to the base 11 in the first direction X under the action of an external force, the rotating assembly 12 can also drive the device to be tested 20 to rotate in the first direction X relative to the base 11. Therefore, through this structure, the lubrication testing device 10 in the present application can realize the rotation of the rotating component 12 in the first direction X and the second direction Y, thereby driving the device to be tested 20 to realize the rotation in the first direction X and the second direction Y, and then realizing the observation of more performance parameters of the device to be tested 20 at different angles.

[0030] The performance parameters include but are not limited to no-load drag torque, temperature rise at different positions, and power output conditions such as torque and speed.

[0031] In addition, in the present application, a locking component 13 is used to realize an active connection between the rotating component 12 and the base 11, so that the rotating component 12 can rotate relative to the base 11 along the first direction X under the action of an external force. Compared with the prior art in which the rotating component 12 is stably connected to the base 11, a larger driving force is required to realize the rotation of the rotating component 12. The structure in the present application only requires a smaller force to realize the rotation of the rotating component 12 relative to the base 11, thereby making the process of driving the rotating component 12 to rotate relative to the base 11 in the first direction X more labor-saving.

[0032] In some application scenarios, when the locking assembly 13 is in a relaxed state, the rotating assembly can be manually pushed to rotate relative to the base 11 in the first direction X, thereby driving the device to be tested 20 to rotate in the first direction X. Manual pushing can reduce the number of driving components, simplify the structure of the lubrication testing device 10, and reduce production costs.

[0033] When the base 11 rotates in the second direction Y, the lubrication testing device 10 further includes a driving member (not shown). The driving member is connected to the base 11 and can be used to drive the base 11 to rotate in the second direction Y. By providing the driving member to drive the base 11 to rotate in the second direction Y, the rotating assembly 12 and the device to be tested 20 can also rotate in the second direction Y.

[0034] The driving member may be a driving member structure shared with the device to be tested 20. Alternatively, in some other embodiments, manual driving may be used to achieve rotation in the second direction Y, which is not limited here.

[0035] Preferably, the plane where the first direction X is located is perpendicular to the plane where the second direction Y is located.

[0036] Please refer to Figure 2 and Figure 3 , Figure 3 It is a schematic diagram of the explosion structure of an embodiment of the lubrication testing device of the present application.

[0037] In an embodiment of the present application, the base 11 includes a chassis 114, and the locking assembly 13 includes a boss 122 and a fixing assembly 131. The boss 122 is fixed to the chassis 114 and is arranged between the rotating assembly 12 and the chassis 114 to support the rotating assembly 12; the rotating assembly 12 is fixedly connected or movably connected to the boss 122 through the fixing assembly 131. The setting of the boss 122 in the present application can play a certain supporting role for the rotating assembly 12, and at the same time can also reduce the contact area between the rotating assembly 12 and the chassis 114, thereby reducing the friction between the chassis 114 and the rotating assembly 12, thereby making it easier for the rotating assembly 12 to rotate relative to the base 11 in the first direction X under the action of external force. In addition, the setting of the boss 122 can also increase the limiting area between the fixing assembly 131 and the chassis 114 by partially increasing the height of the chassis 114, thereby avoiding the phenomenon of shaking of the fixing assembly 131 during the connection process, and improving the connection stability of the fixing assembly 131.

[0038] Furthermore, when the rotating assembly 12 is movably connected to the boss 122 via the fixing assembly 131, the rotating assembly 12 can rotate relative to the base 11 in the first direction X under the action of an external force. In the present application, through the above-mentioned method, compared with the prior art in which the rotating assembly 12 is stably connected to the base 11 and a large driving force is required to realize the rotation of the rotating assembly 12, in the present application, a smaller force can be applied to drive the rotating assembly 12 to rotate in the first direction X relative to the base 11, thereby making the process of rotating the rotating assembly 12 relative to the base 11 in the first direction X more labor-saving.

[0039] In some embodiments, the base 11 further includes a bottom frame. The bottom frame is U-shaped and includes two oppositely disposed extension frames and a connecting frame, with the connecting frame connecting the two extension frames. A chassis 114 is disposed on the two extension frames, and a boss 122 is disposed on a side of the chassis 114 away from the bottom frame. The chassis 114 is used to support the boss 122. By configuring the base 11 as a structure of a bottom frame and a chassis 114, with the chassis 114 disposed on the two extension frames, the chassis 114 can, on the one hand, provide excellent support for the boss 122, the rotating assembly 12, and the device under test 20. On the other hand, compared to directly configuring the chassis 114 as a flat plate structure, when testing different devices under test 20, different sizes of chassis 114 can be selected according to the volume of the different devices under test 20 to support the boss 122, the rotating assembly 12, and the device under test 20. Consequently, when testing a different device under test 20, there is no need to replace the entire base 11, which greatly improves the adaptability of the base 11. In addition, setting the base frame as a U-shaped frame can also greatly reduce the weight of the chassis 114 compared to directly setting the chassis 114 as a flat plate structure, thereby achieving a lightweight setting of the lubrication testing device 10.

[0040] Please refer to Figure 3 and Figure 4 , Figure 4 It is a schematic diagram of the three-dimensional structure of the fixing assembly of an embodiment of the lubrication testing device of the present application.

[0041] To achieve a fixed or movable connection between the rotating assembly 12 and the boss 122, in an embodiment of the present application, coaxially arranged threaded holes 113 are sequentially formed on the chassis 114, the boss 122, and the rotating assembly 12. The fixing assembly 131 includes a stud 132, which is inserted into the threaded hole 113. The stud 132 is threadedly connected to the rotating assembly 12, the boss 122, and the chassis 114 through the threaded hole 113, so that the rotating assembly 12 can be fixed relative to the chassis 114 or rotated along the first direction X. Specifically, the stud 132 can be inserted into the threaded hole 113 and tightened to enhance the strength of the threaded connection between the stud 132 and the threaded hole 113, so that the stud 132 is tightly connected to the rotating assembly 12, the boss 122, and the chassis 114, thereby fixing the rotating assembly 12 relative to the chassis 114. When the stud 132 is loosened to reduce the strength of the threaded connection between the stud 132 and the threaded hole 113, the tightness of the connection between the stud 132 and the rotating assembly 12, the boss 122, and the chassis 114 can be reduced, and the rotating assembly 12 can be rotated relative to the base 11 in the first direction X under the action of an external force. Therefore, in the present application, only the strength of the threaded connection between the stud 132 and the threaded hole 113 needs to be adjusted to achieve a fixed or movable connection between the rotating assembly 12 and the base 11. The entire operation process is quick and can improve the operating efficiency of the staff. In addition, after loosening the stud 132, the rotating assembly 12 is movably connected to the base 11, so that the process of rotating the rotating assembly 12 relative to the base 11 in the first direction X under the action of an external force can also be more labor-saving.

[0042] In an embodiment of the present application, the stud 132 also includes an abutment portion 1321 and an insertion portion 1322, wherein the abutment portion 1321 abuts against the side of the rotating component 12 away from the boss 122; the insertion portion 1322 is inserted into the threaded hole 113; the fixing component 131 also includes a nut 133, and the nut 133 is threadedly connected to the insertion portion 1322 on the side of the chassis 114 away from the boss 122; wherein, when the rotating component 12 is relatively fixed to the base 11, the abutment portion 1321 abuts against the side of the rotating component 12 away from the boss 122, and the nut 133 abuts against the side of the chassis 114 away from the boss 122; when the rotating component 12 can rotate relative to the base 11 along the first direction X, the nut 133 disengages from the end of the chassis 114 away from the boss 122. Specifically, to achieve relative fixation between the rotating assembly 12 and the base 11, the insertion portion 1322 is first inserted into the threaded hole 113, and the abutting portion 1321 is abutted against the side of the rotating assembly 12 facing away from the boss 122. The nut 133 is then screwed into the insertion portion 1322 from the side of the chassis 114 facing away from the boss 122 until the nut 133 abuts against the side of the chassis 114 facing away from the boss 122. This achieves relative fixation between the rotating assembly 12 and the base 11. When the rotating assembly 12 is movably connected relative to the base 11, the nut 133 can be loosened so that the nut 133 no longer abuts against the side of the chassis 114 facing away from the boss 122. Then, driven by an external force, the rotating assembly 12 can be rotated relative to the base 11 in the first direction X. Therefore, in the present application, by adjusting the nut 133 so that the nut 133 abuts or disengages from the side of the chassis 114 facing away from the boss 122, the fixed or movable connection between the rotating assembly 12 and the base 11 can be controlled. The entire operation process is simple and labor-saving, which can improve the operator's operating efficiency. In addition, the arrangement of the nut 133 and the stud 132 also has a low structural cost.

[0043] When the rotating assembly 12 rotates relative to the base 11 in the first direction X, the abutting portion 1321 and the rotating assembly 12 may or may not abut. When the abutting portion 1321 and the rotating assembly 12 abut, the rotating assembly 12 does not tilt when rotating relative to the base 11 in the first direction X, thereby making the rotation process more stable. If the abutting portion 1321 and the rotating assembly 12 do not abut, that is, there is a certain distance between the rotating assembly 12 and the abutting portion 1321, the friction between the abutting portion 1321 and the rotating assembly 12 can be reduced, and thus the rotation of the rotating assembly 12 in the first direction X relative to the base 11 under external force can also be more labor-saving.

[0044] In some other embodiments, the fixing component 131 may also adopt a structure such as a screw, and the specific form of the fixing component 131 is not limited here.

[0045] Please continue reading Figures 1 to 3In the embodiment of the present application, the lubrication testing device 10 further includes a connector 14 disposed on the chassis 114. The connector 14 is configured to connect to the driver to drive the chassis 114 to rotate relative to the workbench in the second direction Y. The provision of the connector 14 effectively increases the contact area between the base 11 and the driver, thereby improving the connection stability between the driver and the base 11, and further enhancing the reliability of the lubrication testing device 10 in achieving rotation in the second direction Y.

[0046] The connecting member 14 may be a circular connecting member 14, a square connecting member 14, or an irregularly shaped connecting member 14, without limitation. The above configuration allows the connecting member 14 to be adapted to different drive members, thereby improving the adaptability of the lubrication testing device 10.

[0047] Among them, in some other embodiments, when the base 11 is manually driven to rotate in the second direction Y, it can be achieved by pushing the connecting member 14, and by pushing the connecting member 14, it can be more labor-saving to a certain extent compared to directly pushing the base 11 manually.

[0048] In some other embodiments, the driving member may also be inserted into the chassis 114 via a driving shaft, so that the chassis 114 is driven to rotate in the second direction relative to the workbench through the rotation of the driving shaft.

[0049] In an embodiment of the present application, the rotating assembly 12 includes a rotating disk 121. A plurality of scale lines 123 are arranged at intervals on the rotating disk 121, and the scale lines 123 are used to indicate the rotation angle of the rotating disk 121 in the first direction X. A pointer 141 is provided on the side of the connecting member 14 facing the rotating disk 121. The pointer 141 is provided corresponding to the rotating disk 121, and the pointer 141 is used to point to the scale lines 123. By providing the scale lines 123 and the pointer 141, the operator can know the angle of rotation of the rotating disk 121 in the first direction X according to the scale information on the scale lines 123 pointed by the pointer 141; and the provision of the pointer 141 can also facilitate the operator to read the scales on the scale lines 123 more accurately, and can also make it more convenient for the operator to read the scales, thereby improving the operator's operating experience.

[0050] The rotating disk 121 may be a circular rotating disk 121 or a rotating disk 121 structure combining a semicircular shape and a square shape, which is not limited here.

[0051] When the rotating disk 121 is a circular rotating disk 121, scale lines 123 can be set on the rotating disk 121 along the circumference of the rotating disk 121. This setting allows the operator to observe the angle of rotation of the rotating disk 121 in the first direction X, which can be any angle between 0-360°. When the rotating disk 121 is a rotating disk 121 that combines a semicircular and square shape, scale lines 123 can be set on the circumference of the semicircular rotating disk 121. This setting allows the operator to observe the angle of rotation of the rotating disk 121 in the first direction X, which can be any angle between 0-180°. Through the above setting, it is convenient for the operator to observe the rotation angle of the rotating disk 121, thereby making it easier to understand the performance parameters of the device under test 20 at any angle in the first direction X.

[0052] In the embodiment of the present application, a fixing block 142 is provided on the side of the connecting member 14 facing the rotating disk 121, and the pointer 141 is disposed above the fixing block 142; wherein, the fixing block 142 is used to fix the pointer 141. The provision of the fixing block 142 can increase the contact area between the pointer 141 and the connecting member 14, thereby effectively improving the connection strength between the pointer 141 and the connecting member 14.

[0053] The fixing block 142 is provided with a first through hole, and the connecting member 14 is provided with a second through hole corresponding to the first through hole. The fixing block 142 can be sequentially inserted into the first through hole and the second through hole by fasteners to fix the fixing block 142 to the connecting member 14. Of course, in some other embodiments, the fixing block 142 can also be welded to the connecting member 14 to ensure the connection strength between the fixing block 142 and the connecting member 14, which is not limited here.

[0054] See also Figure 2To facilitate the installation of the device to be tested 20, in an embodiment of the present application, a strip groove 124 is provided on the rotating assembly 12, and the strip groove 124 is provided with multiple mounting positions (not shown in the figure). The lubrication testing device 10 also includes a support column 15, which is removable and selectively installed at a certain mounting position. The support column 15 is used to support the device to be tested 20. In the present application, the provision of the support column 15 can disperse the gravity exerted by the device to be tested 20 on the rotating assembly 12, thereby reducing the magnitude of the gravity borne by the rotating assembly 12, and thus making the rotation of the rotating assembly 12 in the first direction X more labor-saving. In addition, by providing the strip groove 124 and providing multiple mounting positions on the strip groove 124, compared to ordinary circular mounting grooves with only one mounting position, in the present application, different mounting positions can be selected for installation according to the shape and volume of the device to be tested 20 when installing the support column 15, thereby greatly improving the flexibility and adaptability of the lubrication testing device 10. In addition, the provision of the strip grooves 124 can also absorb and disperse the stress and vibration between the support column 15 and the rotating assembly 12 to a certain extent, thereby improving the connection stability and reliability of the support column 15 to the rotating assembly 12 .

[0055] The number of the strip grooves 124 can be 2, 3, or more, which is not limited here. The number of the support columns 15 is set corresponding to the number of the strip grooves 124.

[0056] In an embodiment of the present application, three strip-shaped slots 124 are provided on the rotating assembly 12, and three support columns 15 are provided corresponding to the three strip-shaped slots 124. The device to be tested 20 includes a motor 21 and a reducer 22 connected to each other, wherein the motor 21 and the reducer 22 are arranged along a third direction Z, and the input end and the output end of the reducer 22 are arranged along a fourth direction O. The three support columns 15 are respectively connected to the input end of the motor 21, the input end of the reducer 22, and the output end of the reducer 22. The plane in which the third direction Z and the fourth direction O lie is coplanar with the plane in which the first direction X lies, and the third direction Z and the fourth direction O are perpendicular. With this arrangement, the three support columns 15 can be arranged in a triangular configuration. Due to the strong stability of the triangle, the support stability of the support columns 15 on the device to be tested 20 can be greatly improved, thereby improving the reliability of the lubrication testing device 10.

[0057] In some embodiments, the support column 15 can be mounted on the mounting position of the strip groove 124 using fasteners, which provides greater flexibility. Alternatively, the support column 15 can be connected to the rotating assembly 12 by welding, which provides a stronger connection and thus improves the reliability of the lubrication testing device 10. This is not a limitation.

[0058] It should be noted that terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they may be slightly tilted. Terms such as "parallel" and "perpendicular" do not imply that components are absolutely parallel or perpendicular to each other, but rather that they may form a certain angular deviation. For example, "horizontal" simply means that its direction is more horizontal than "vertical" and does not mean that the structure must be completely horizontal, but rather that it may be slightly tilted. Furthermore, terms such as "center," "longitudinal," "transverse," "length," "width," "thickness," "up," "down," "front," "back," "left," "right," "vertical," "horizontal," "top," "bottom," "inside," "outside," "clockwise," and "counterclockwise" indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships typically used when the products of this application are used. These terms are intended solely to facilitate the description of the embodiments of this application and to simplify the description, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0059] It is to be understood that the meaning of "plurality" herein is at least two, such as two, three, etc., unless otherwise specifically stated. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices. The term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B may represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " herein generally indicates that the associated objects before and after are in an "or" relationship.

[0060] The above description is only an implementation method of the present application and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of this application, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present application.
