According to the embodiment of the present disclosure, the angle at which the supporting arm 220 can rotate relative to the central axis of the rotating shaft 230 depends on the arrangement of the rotating slot 213 of the base 210, and specifically depends on the included angle formed by a side surface of the rotating slot 213 close to the second side 212 and a side surface extending from the first side 211 to the second side 212, in order to meet the requirement of the motor performance test under all possible operating conditions, the included angle formed by a side surface of the rotating slot 213 close to the second side 212 and a side surface extending from the first side 211 to the second side 212 may be set to a value not less than 90 °, so that the angle at which the supporting arm 220 can rotate in the rotating slot 213 around the central axis of the rotating shaft 230 under the action of the second acting force is not less than 90 °, thereby driving the motor 101 may be in a state of any angle between 0 ° and 90 ° with the horizontal plane, and meeting the requirement of.

Referring to fig. 2B, the testing apparatus 200 for testing a motor according to the embodiment of the present disclosure may further include a first arm concurrent member 250, and accordingly, two opposite side walls of the base 210 forming the rotation groove 213 may further be provided with a guide groove 214, the guide groove 214 is an arc-shaped structure, and in a case that the rotation shaft 230 is hinged to the arm 220 and the base 210, a central point of the arc-shaped structure is on a central axis of the rotation shaft 230, and the position of the guide groove 214 is higher than a position where the rotation shaft 230 is hinged to the arm 220 and the base 210, specifically, the position of the guide groove 214 is closer to a second end of the base 210 opposite to the first end of the arm 220 than the rotation shaft 230, and more specifically, the guide groove 214 may be disposed along an extending direction of the rotation groove 213. The first arm fixing member 250 may be inserted through two arc-shaped guide grooves 214 of the base 210, which are oppositely disposed, to define the position of the arm 220 hinged to the base 210. Specifically, when the arm 220 is hinged to the base 210 via the shaft 230, the first arm fixing member 250 can be detachably disposed in the set of arc-shaped guide slots 214 at a position where the arm 220 is close to the side wall of the first side 211 of the base 210, so as to define the position of the arm 220.

As shown in fig. 2C, the first arm fixing member 250 may specifically be a fixing pin structure having a threaded rod and a nut, for example, when the motor testing apparatus 200 is used to test the motor 101, if an included angle of the motor 101 with respect to a horizontal plane needs to be changed, the nut of the first arm fixing member 250 may be rotated to loosen the fastening of the first arm fixing member 250 to the arm, and at the same time, the rotating shaft fixing member 240 releases the rotating shaft 230 by a first acting force, so that the arm is rotated to a desired angle under the action of a second acting force, after the rotating shaft is rotated to the desired angle, the rotating shaft fixing member 240 fixes the rotating shaft 230 by the first acting force, and the first arm fixing member 250 is tightened to further limit the position of the arm 220, so as to ensure that the arm 220 can be firmly fixed to the angle required by the tester.

Referring to fig. 2C, the motor testing apparatus 200 may further include a second arm fixing member 260, and the second arm fixing member 260 may have the same structure or a different structure from the first arm fixing member 250. The second arm fixing member 260 is disposed through the guide groove 214 and the arm 220 to define the position of the arm 220. Specifically, the support arm 220 is further provided with a second through hole 222 at a position close to the first through hole 221 for passing through the rotating shaft 230, the position of the second through hole 222 relative to the first through hole 221 specifically corresponds to the position of the guide groove 214 relative to the third through hole 215 of the base 210, so that when the support arm 220 is hinged to the base 210, the position of the second through hole 222 corresponds to the position of the guide groove 214 of the arc top, so that the second support arm fixing member 260 can simultaneously pass through the second through hole 222 and the guide groove 214 to further define the position of the support arm 220, wherein the specification size of the selected second support arm fixing member 260 and the first support arm fixing member 250 should depend on the size of the second through hole 222 of the support arm 220 and the size of the guide groove 214, and details thereof are not repeated herein. It will be appreciated that, in order to ensure a stable fixing of the arm 220, the second through hole 222 of the arm 220 should be sized to match the size of the guide groove 214, so as to ensure that the arm 220 does not shake in the vertical direction when the arm 220 is hinged to the base 210.

In the process of testing the motor 101 by the motor testing device 200, if the included angle of the motor 101 relative to the horizontal plane needs to be changed, the clamping of the first arm fixing part 250 and the second arm fixing part 260 to the support arm can be released simultaneously, the rotating shaft 230 is released by the rotating shaft fixing part 240 through the first acting force, so that the support arm rotates to the required angle under the action of the second acting force, after the support arm rotates to the required angle, the rotating shaft 230 is fixed by the rotating shaft fixing part 240 through the first acting force, and the further limitation of the position of the support arm 220 can be realized by screwing the first arm fixing part 250 and the second arm fixing part 260, namely, the support arm 220 can be firmly fixed to the angle required by a tester through the two support arm fixing parts and the rotating shaft fixing part.

According to the embodiment of the present disclosure, in order to improve the limit fixing effect of the second arm fixing member 260 on the arm in one step, the second through hole 222 may be disposed at a position where the central axis of the arm 220 is located, for example, so that the second through hole 222 is axisymmetrical with respect to the central axis of the arm 220.

According to the embodiment of the present disclosure, as shown in fig. 2B, in the case that the second through hole 222 is provided at the position of the central axis of the arm 220, a surface of any one of two opposite side walls of the base 210 forming the rotation groove 213 may be provided with an angle scale along the guide groove 214. In particular, the first side wall can also be provided with an angle scale on the surface facing away from the second side wall, for example, along the arc-shaped guide groove 214, the scale range of the angle scale can be, for example, 0 ° to 90 °, the 0 ° scale can be provided, for example, in the direction perpendicular to the extension direction of the rotation groove 213, the 90 ° scale can be provided in the extension direction of the rotation groove 213, and the precision of the angle scale can be, for example, precise to 1 degree. It is to be understood that the scale range, the scale start position, the scale end position and the precision of the angle scale are only examples to facilitate understanding of the present disclosure, and the present disclosure does not limit the same.

Considering that the second through hole 222 can be disposed at the position of the central axis of the support arm 220, for example, the position of the scale of the second support arm fixing member 260 passing through the second through hole 222 is the position of the central axis of the support arm, therefore, according to the angle scale corresponding to the position of the second support arm fixing member 260, the angle of rotation of the support arm 220 around the central axis of the rotating shaft 230 in the rotating groove 213 can be determined, and the initial position of rotation of the support arm 220 relative to the central axis of the rotating shaft 230 can be set to the position of the support arm 220 in the vertical direction, or any other position, for example, according to the angle scale corresponding to the second support arm fixing member 260 when the support arm 220 is at the initial position and the angle scale corresponding to the second support arm fixing member 260 at the current position of the support arm 220, the angle of rotation of the support arm 220 can be determined, so that a tester can accurately, and thus the angle of the motor 101 to the horizontal is accurately determined.
