[0002] With the continuous development of the car model industry, the performance requirements for car model motors are also getting higher and higher. Therefore, it is necessary to use tooling test fixtures to test the performance of motors.

[0003] In traditional solutions, motors are typically secured with screws, making the entire process of disassembling and testing the motor particularly cumbersome and significantly reducing the efficiency of motor performance testing.

[0004] Therefore, it is particularly important to provide a motor performance testing device that can quickly disassemble and assemble the motor. Utility Model Content

[0005] To address the technical problem of low efficiency in motor performance testing in existing technologies, this application provides a motor performance testing device.

[0006] This application proposes a motor performance testing device, including a motor, a first fixed base, a rotating shaft, and a test load; The first fixed base is provided with a first clamping assembly, which includes an upper clamping part and a lower clamping part. The motor is clamped between the upper clamping part and the lower clamping part. One end of the rotating shaft is connected to the output shaft of the motor. The test load is disposed on the rotating shaft. It also includes a first tensioning component, which is used to drive the first clamping component to loosen or clamp the motor.

[0007] Preferably, the first tensioning assembly includes a connecting rod, a wrench, and a pad; One end of the connecting rod is fixedly connected to the lower clamping part, and the other end is movably passed through the upper clamping part and provided with a connecting seat. The wrench is rotatably connected to the connecting seat. The pad is provided between the upper clamping part and the connecting seat. The pad is provided with a recessed part. One end of the wrench connected to the connecting seat is provided with a protrusion that cooperates with the recessed part. The wrench can switch between a tightened state and a loosened state. When the wrench is in the tightened state, the protrusion and the recessed portion are pressurized and squeeze the pad. When the wrench is in the loosened state, the protrusion disengages from the recessed portion.

[0008] Preferably, the pad is an elastic pad.

[0009] Preferably, the first clamping component is provided with locking teeth, which engage with the motor.

[0010] Preferably, the clamping teeth are arranged in a ring at intervals on the upper clamping part and the lower clamping part.

[0011] Preferably, it also includes a connecting sleeve, the output shaft of the motor being detachably connected to one end of the connecting sleeve, and the other end of the connecting sleeve being fixedly connected to the rotating shaft.

[0012] Preferably, the connecting sleeve is embedded with a second clamping assembly, the second clamping assembly including at least two clamping plates for clamping the output shaft of the motor, and an elastic element connecting adjacent clamping plates; It also includes a second tensioning component, which is used to drive the second clamping component to loosen or clamp the output shaft of the motor.

[0013] Preferably, the second tensioning assembly includes an adjusting screw, a fixing rod, and a slider; Both the connecting sleeve and the second clamping assembly are funnel-shaped, and their diameters gradually increase from one end near the output shaft of the motor to the other end. One end of the adjusting screw is exposed outside the connecting sleeve, and the other end is threaded downward through the connecting sleeve. One end of the fixing rod is fixedly connected to the adjusting screw, and the other end passes downward through the slider and has a boss. The slider is located between the second clamping assembly and the rotating shaft, and the slider has a guide slope that cooperates with the rotating shaft. The adjusting screw can switch between a tightened state and a loosened state. When the adjusting screw is in the tightened state, the slider slides down and presses the second clamping assembly so that the second clamping assembly clamps the output shaft of the motor.

[0016] Compared with the prior art, the beneficial results of this application are as follows: (1) By setting a first clamping component for installing the motor, when the wrench is turned to the tightening state, the protrusion of the wrench cooperates with the recess on the pad and squeezes the pad, thereby pressing down the upper clamping part, so that the first clamping component clamps the motor. When the wrench is turned to the loosening state, the protrusion of the wrench disengages from the recess on the pad, and the first clamping component releases the motor, thereby realizing the quick disassembly and assembly of the motor and improving the testing efficiency.

[0017] (2) By setting a connecting sleeve and a second clamping assembly, when the adjusting screw is tightened, the adjusting screw drives the slider to slide down, the slider squeezes the second clamping assembly, the clamping piece of the second clamping assembly tightens and clamps the output shaft of the motor.

This enables quick disassembly and assembly between the output shaft and the rotating shaft of the motor, improving testing efficiency. Attached Figure Description

[0021] In the following detailed description, reference is made to the accompanying drawings, which form part of the detailed description and illustrate illustrative specific embodiments in which the present application may be practiced. In this regard, directional terms such as “top,” “bottom,” “left,” “right,” “up,” “down,” etc., are used with reference to the orientation of the described figures. Because components of the embodiments can be positioned in several different orientations, directional terms are used for illustrative purposes and are by no means limiting. It should be understood that other embodiments may be utilized or logical changes may be made without departing from the scope of the present application. Therefore, the following detailed description should not be taken in a limiting sense, and the scope of the present application is defined by the appended claims.

[0022] This application discloses a motor performance testing device. The specific structure of the motor performance testing device according to an embodiment of this application will be described below with reference to the accompanying drawings.

[0023] Please refer to Figure 1 The motor performance testing device includes a base 1 and a motor 2, a first fixed seat 3, a rotating shaft 4, a test load 5, a coupling 6, a second fixed seat 7, and a driven assembly 8, all mounted on the base 1. The motor 2 is mounted on the first fixed seat 3, the test load 5 is fixedly sleeved on the rotating shaft 4, and the driven assembly 8 is rotatably mounted on the second fixed seat 7. One end of the rotating shaft 4 is connected to the output shaft 21 of the motor 2, and the other end of the rotating shaft 4 is connected to the coupling 6. The other end of the coupling 6 extends into the second fixed seat 7 and connects to the driven assembly 8.

[0024] In this embodiment, motor 2 is a car model motor, test load 5 is a weight, and driven component 8 is a propeller.

[0025] When testing the performance of motor 2, adjust the rated output voltage of motor 2. The output shaft 21 of motor 2 drives the rotating shaft 4 and the test load 5 to rotate together. The rotating shaft 4 drives the driven component 8 to rotate through the coupling 6. At this time, according to the rotational inertia applied to the rotating shaft 4 by the installed test load 5, record the corresponding output current value of motor 2 and compare it with the standard rated current value. This will enable the automated testing of the rated torque value of motor 2.

[0026] Continue to refer to Figure 1 In one specific embodiment, the first fixed base 3 is provided with a first clamping component 9 and a first tensioning component 10. The first clamping component 9 is used to clamp the motor 2, and the first tensioning component 10 is used to drive the first clamping component 9 to loosen or tighten the motor 2, so as to realize the quick assembly and disassembly of the motor 2.

[0027] For details, please refer to Figure 2 and Figure 3 The first clamping assembly 9 includes an upper clamping part 91 and a lower clamping part 92, with a clamping opening formed between one end of the upper clamping part 91 and the lower clamping part 92. The motor 2 is clamped between the upper clamping part 91 and the lower clamping part 92. A first tensioning assembly 10 is disposed in the clamping opening, and the first tensioning assembly 10 includes a connecting rod 101, a wrench 102, and a pad 103.

[0028] In one specific embodiment, a pad 103 is disposed on the upper clamping part 91, and the lower end of the connecting rod 101 is fixed to the lower clamping part 92 by a nut. The connecting rod 101 movably passes through the lower clamping part 92, the upper clamping part 91, and the pad 103, and a connecting seat 1011 is integrally formed at its upper end. The wrench 102 is rotatably connected to the connecting seat 1011 by a pin. A recess 1031 is formed on the pad 103, and a protrusion 1021 that mates with the recess 1031 is formed at one end of the wrench 102 that connects to the connecting seat 1011.

[0029] The wrench 102 can switch between a tightened and a loosened state. When the wrench 102 is tightened, the protrusion 1021 of the wrench 102 is pressurized against the recess 1031 of the pad 103, thereby compressing the upper clamping part 91 and causing it to deform. This reduces the clamping opening between the upper clamping part 91 and the lower clamping part 92, thus clamping the motor 2. When the wrench 102 is loosened, the protrusion 1021 of the wrench 102 disengages from the recess 1031 of the pad 103, the upper clamping part 91 returns to its original shape, and the motor 2 is released. In this way, the motor 2 can be quickly assembled and disassembled by rotating the wrench 102, improving the testing efficiency of the motor 2.

[0030] In a preferred embodiment, the pad 103 is an elastic pad, and the elasticity of the rubber pad can prevent the wrench 102 from making hard contact with the pad 103 and causing wear.

[0031] In this embodiment, the pad 103 is specifically a rubber pad. In other embodiments, the pad may be made of other specific elastic materials, which are not limited here.

[0032] In a preferred embodiment, the first clamping component 9 is provided with a locking tooth 93, which engages with a groove on the outer peripheral surface of the motor 2, so that the first clamping component 9 can better clamp the motor 2.

[0033] In this embodiment, multiple teeth 93 are provided at annular intervals on the inner circumferential surfaces of the upper clamping portion 91 and the lower clamping portion 92.

[0034] Please see Figures 4-6 A connecting sleeve 11 is provided between the output shaft 21 of the motor 2 and the rotating shaft 4. The output shaft 21 of the motor 2 is detachably connected to one end of the connecting sleeve 11, and the other end of the connecting sleeve 11 is fixedly connected to the rotating shaft 4. The connecting sleeve 11 contains a second clamping component 12 for clamping the output shaft 21 of the motor 2, and a second tensioning component 13 is also provided inside the connecting sleeve 11. The second tensioning component 13 is used to drive the second clamping component 12 to loosen or clamp the output shaft 21 of the motor 2, so as to realize the quick assembly and disassembly of the output shaft 21 of the motor 2.

[0035] Specifically, the second clamping assembly 12 includes at least two clamping plates 121 for clamping the output shaft 21 of the motor 2, and an elastic element 122 is connected between two adjacent clamping plates 121.

[0036] In this embodiment, the second clamping assembly 12 is provided with three clamping pieces 121.

[0037] In this embodiment, the elastic element 122 is a spring. In other embodiments, the elastic element may also be made of other specific elastic materials, which are not limited here.

[0038] The second tensioning assembly 13 includes an adjusting screw 131, a fixing rod 132, and a slider 133. Both the connecting sleeve 11 and the second clamping assembly 12 are funnel-shaped, and their diameters gradually increase from one end near the output shaft 21 of the motor 2 to the other end. One end of the adjusting screw 131 is exposed outside the connecting sleeve 11 for user operation, and the other end is threaded vertically downward through the connecting sleeve 11. The upper end of the fixing rod 132 is fixedly connected to the adjusting screw 131, and the lower end is vertically downward through the slider 133 and has a boss 1321. The slider 133 is located between the second clamping assembly 12 and the rotating shaft 4, and the slider 133 has a guide slope 1331 that cooperates with the rotating shaft 4.

[0039] The adjusting screw 131 can switch between a tightened and a loosened state. When the adjusting screw 131 is tightened downwards, it causes the slider 133 to slide down by contact. The slider 133, through the cooperation of the guide slope 1331 and the rotating shaft 4, displaces horizontally, thereby squeezing the second clamping assembly 12. This causes the clamping piece 121 of the second clamping assembly 12 to tighten and clamp the output shaft 21 of the motor 2. When the adjusting screw 131 is loosened upwards, it causes the fixing rod 132 to move upwards. The fixing rod 132, through the boss 1321, causes the slider 133 to slide upwards. The slider 133 releases the second clamping assembly 12, and the clamping piece 121 of the second clamping assembly 12 releases the output shaft 21 of the motor 2 under the elastic force of the elastic element 122. In this way, the output shaft 21 of the motor 2 can be quickly installed and removed by simply turning the adjusting screw 131, improving the testing efficiency of the motor 2.

[0040] In summary, the motor performance testing device proposed in this application has the following beneficial effects: By setting a first clamping assembly 9 for installing motor 2, when the wrench 102 is turned to the tightening state, the protrusion 1021 of the wrench 102 engages with the recess 1031 on the pad 103 and squeezes the pad 103, thereby pressing down the upper clamping part 91 and clamping the motor with the first clamping assembly 9. When the wrench 102 is turned to the loosening state, the protrusion 1021 of the wrench 102 disengages from the recess 1031 on the pad 103, and the first clamping assembly 9 releases the motor 2, thereby enabling quick installation and removal of motor 2 and improving testing efficiency.

[0041] By setting up the connecting sleeve 11 and the second clamping assembly 12, when the adjusting screw 131 is tightened, the adjusting screw 131 drives the slider 133 to slide down, and the slider 133 squeezes the second clamping assembly 12. The clamping piece 121 of the second clamping assembly 12 tightens and clamps the output shaft 21 of the motor 2. When the adjusting screw 131 is loosened, the adjusting screw 131 drives the slider 133 to slide up through the fixing rod 132. The slider 133 releases the second clamping assembly 12, and the clamping piece 121 of the second clamping assembly 12 releases the output shaft 21 of the motor 2. This enables quick assembly and disassembly between the output shaft 21 of the motor 2 and the rotating shaft 4, further improving testing efficiency.

[0042] It is obvious that those skilled in the art can make various modifications and alterations to the embodiments of this application without departing from the spirit and scope of this application. In this way, this application also aims to cover such modifications and alterations if they fall within the scope of the claims and their equivalents. The word "comprising" does not exclude the presence of other elements or steps not listed in the claims. The simple fact that certain measures are described in mutually different dependent claims does not indicate that a combination of these measures cannot be used for profit. Any reference numerals in the claims should not be considered limiting in scope.
