Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0032] Unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0033] Currently, when high-voltage electronic speed controllers are used with high-speed motors for load testing, due to the lack of corresponding testing fixtures, the only way to conduct load testing is to mount the high-voltage electronic speed controller with the high-speed motor on a wireless remote-controlled model car. However, due to the limitations of the testing environment, it is difficult to collect relevant test data simultaneously during the testing process, resulting in low test accuracy.

[0034] Therefore, this utility model provides an embodiment of a testing fixture 100, which can improve testing accuracy.

[0035] To facilitate the reader's understanding of the concept of this utility model embodiment, the specific structure of the test fixture 100 is described below:

[0036] Please see Figures 1 to 3The testing fixture 100 includes a support assembly 1 and a testing assembly 2. The support assembly 1 includes a base 11, a first support 12, and a second support 13, which are spaced apart from each other on the base 11. The testing assembly 2 includes a motor 21, a speed controller (not shown), a testing instrument (not shown), a load 22, a first transmission wheel 23, a second transmission wheel 24, and a transmission belt 25. The motor 21 is mounted on the first support 12, the speed controller is electrically connected to the motor 21, and the testing instrument is electrically connected to the speed controller. The load 22 is rotatably mounted on the second support 13. The first transmission wheel 23 is connected to the motor 21, the second transmission wheel 24 is connected to the load 22, and the transmission belt 25 is wound around the first transmission wheel 23 and the second transmission wheel 24. It is understood that the testing instrument (not shown) includes, but is not limited to, an oscilloscope. When the testing instrument is an oscilloscope, during the testing process, the oscilloscope can simultaneously acquire relevant test data of the speed controller. For example, the stability of the speed controller's output voltage can be determined through the PWM waveform of the oscilloscope.

[0037] The above method not only enables the speed controller to be tested with the motor 21 under load 22, but also enables the tester to collect relevant test data synchronously, reducing the data acquisition delay caused by environmental limitations (such as site limitations, transmission interference, etc.) when tested on a remote control model car, and improving the test accuracy.

[0038] Regarding the aforementioned support component 1, please refer to some embodiments. Figure 3 and Figure 4 The base 11 is provided with a first sliding groove 111; it also includes a first screw connector 3, which can slide along the first sliding groove 111. One end of the first screw connector 3 passes through the first sliding groove 111 and is screwed to the first bracket 12. The other end of the first screw connector 3 extends out of the first sliding groove 111 and abuts against the side of the base 11 opposite to the first bracket 12. After the first bracket 12 moves to a preset position, the first screw connector 3 locks the first bracket 12 to the base 11. In this way, the first bracket 12 can be moved, thereby adjusting the distance between the first bracket 12 and the second bracket 13, so as to adapt to the combination structure of the first transmission wheel 23, the second transmission wheel 24 and the transmission belt 25 of different sizes, realize multiple speed ratios, and meet the needs of the speed controller and motor 21 for load 22 testing under different speed conditions.

[0039] Furthermore, in some embodiments, please refer to Figure 3 and Figure 4The base 11 is provided with a first groove 112, and a first sliding groove 111 communicates with the bottom of the first groove 112. The other end of the first screw connector 3 extends out of the first sliding groove 111 and abuts against the bottom of the first groove 112. The first groove 112 is used to accommodate the other end of the first screw connector 3. In this way, the first screw connector 3 can be prevented from protruding from the base 11 on the side away from the first bracket 12, improving the compactness of the structure and reducing the probability of the first screw connector 3 becoming loose due to collision.

[0040] Furthermore, in some embodiments, please refer to Figure 1 and Figure 2 The first bracket 12 is provided with a second sliding groove 121; it also includes a second screw connector 5, which can slide along the second sliding groove 121. One end of the second screw connector 5 passes through the second sliding groove 121 and is screwed onto the motor 21, while the other end of the second screw connector 5 extends out of the second sliding groove 121 and abuts against the side of the first bracket 12 away from the motor 21. The second screw connector 5 locks the motor 21 to the first bracket 12. In this way, the movement of the second screw connector 5 can be realized to adapt to the installation of motors 21 of different sizes.

[0041] Furthermore, in some embodiments, please refer to Figure 1 and Figure 2 The first bracket 12 is provided with a second groove 122, and a second sliding groove 121 communicates with the bottom of the second groove 122. The other end of the second screw connector 5 extends out of the second sliding groove 121 and abuts against the bottom of the second groove 122. The second groove 122 is used to accommodate the other end of the second screw connector 5. In this way, the second screw connector 5 can be prevented from protruding from the side of the first bracket 12 away from the motor 21, improving the compactness of the structure and reducing the probability of the second screw connector 5 becoming loose due to collision.

[0042] Furthermore, in some embodiments, please refer to Figure 3 and Figure 4 The base 11 is provided with a clearance notch 113, which is located below the first support 12. The end of the motor 21 away from the first support 12 is at least partially accommodated in the clearance notch 113. In this way, not only can the probability of interference between the base 11 and the motor 21 be reduced, but the compactness of the structure can also be improved, which helps to reduce the overall volume of the test fixture 100.

[0043] Please see Figure 3 and Figure 4The testing fixture 100 also includes a limiting component 4, which is disposed on the base 11 and abuts against the first bracket 12. The limiting component 4 is used to restrict the movement of the first bracket 12 when the first screw connector 3 becomes loose. Considering that the first screw connector 3 may become loose due to vibration during long-term use, the limiting component 4 can restrict the movement of the first bracket 12 when the first screw connector 3 becomes loose due to vibration, thereby reducing the impact of the movement of the first bracket 12 on the accuracy of the test.

[0044] Regarding the aforementioned limiting component 4, please refer to some embodiments. Figure 3 and Figure 4 The limiting component 4 includes a limiting seat 41 and a limiting member 42. The limiting seat 41 is fixed to the base 11 and has a screw hole 411. The limiting member 42 has a screw connection portion 421, which is screwed into the screw hole 411. The screw connection portion 421 at least partially penetrates the screw hole 411 and abuts against the first bracket 12. Through this method, the limiting member 42 can be extended and retracted, allowing it to extend and retract synchronously when the first bracket 12 moves and adjusts its position, thus maintaining contact between the limiting member 42 and the first bracket 12, thereby maintaining the limiting effect of the limiting member 42 on the first bracket 12.

[0045] Furthermore, in some embodiments, please refer to Figure 3 and Figure 4 The base 11 is provided with a through hole 114 and a third groove 115, the through hole 114 communicating with the bottom of the third groove 115; it also includes a third screw connector 6, one end of the third screw connector 6 passing through the through hole 114 and screwed to the limiting seat 41, the other end of the third screw connector 6 extending out of the through hole 114 and abutting against the bottom of the third groove 115, the third groove 115 being used to accommodate the other end of the third screw connector 6. Through this method, the third screw connector 6 can be prevented from protruding from the side of the base 11 away from the limiting seat 41, improving the compactness of the structure and reducing the probability of the third screw connector 6 loosening due to impact.

[0046] Furthermore, in some embodiments, please refer to Figure 3 and Figure 4 There are two sets of limiting components 4, which are symmetrically arranged on the base 11. One limiting component 4 abuts against one side of the first bracket 12, and the other limiting component 4 abuts against the other side of the first bracket 12. In this way, the uniformity of the limiting force can be improved.

[0047] For test component 2 mentioned above, please refer to Figure 5In some embodiments, the load 22 includes a blade clamp 221, a blade 222, and a nut 223. The blade clamp 221 is rotatably mounted on the second bracket 13 and connected to the second transmission wheel 24. The nut 223 is screwed onto the blade clamp 221, and the blade 222 is inserted between the blade clamp 221 and the nut 223, with the nut 223 pressing the blade 222 firmly into the blade clamp 221. This method simulates the rotating load 22 in a real environment, improving the reliability of the test.

[0048] Please see Figure 5 The test fixture 100 also includes a first bearing 7, which is fixed to the first bracket 12, and the motor 21 shaft of the motor 21 is connected to the first bearing 7; and / or, it also includes a second bearing 8, which is fixed to the second bracket 13, and the load 22 is connected to the second bearing 8. Through the above methods, the rotational friction of the motor 21 shaft of the motor 21 can be reduced, thereby improving transmission efficiency; and / or, the rotational friction of the load 22 can be reduced, thereby improving transmission efficiency.

[0049] This utility model provides a testing fixture 100, including a support component 1 and a testing component 2. The support component 1 includes a base 11, a first bracket 12, and a second bracket 13, which are spaced apart from each other on the base 11. The testing component 2 includes a motor 21, a speed controller, a testing instrument, a load 22, a first transmission wheel 23, a second transmission wheel 24, and a transmission belt 25. The motor 21 is mounted on the first bracket 12, the speed controller is electrically connected to the motor 21, and the testing instrument is electrically connected to the speed controller. The load 22 is rotatably mounted on the second bracket 13. The first transmission wheel 23 is connected to the motor 21, the second transmission wheel 24 is connected to the load 22, and the transmission belt 25 is wound around the first transmission wheel 23 and the second transmission wheel 24. Through this method, the testing fixture 100 of this utility model can not only enable the speed controller to perform load testing with the motor 21, but also simultaneously collect relevant test data through the testing instrument, thereby improving the testing accuracy.
