Description

Technical Field

[0001] This utility model relates to the field of testing fixtures for brushless generators, and more particularly to a testing fixture for a brushless generator. Background Technology

[0002] The brushless motor controller tester is a portable testing device primarily used for quickly diagnosing the winding condition, Hall element function, phase angle type (60 degrees or 120 degrees), and phase sequence of brushless motors in electric vehicles. This instrument also has the function of testing the performance of brushless controllers. It is compatible with both separate and integrated electric vehicle controllers; the former separates the main body and display components, while the latter uses an integrated design.

[0003] The inventors discovered during routine use of the brushless motor controller tester that the tester needs to be connected to the power supply via a cable. Since the tester needs to be moved when testing the brushless motor, the cable may come loose from the power supply port, causing the tester to fail to start and thus causing problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a testing fixture for a brushless generator.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a testing fixture for a brushless generator, comprising a tester and a power supply, a connecting wire fixedly connected to the side of the tester, the other end of the connecting wire being inserted into the interior of the power supply, a detection wire fixedly connected to the side of the tester, a clip fixedly connected to one end of the detection wire, an adjustment knob provided on the surface of the tester and the power supply, an anti-disengagement device provided on the surface of the power supply, the anti-disengagement device comprising a rectangular plate fixedly connected to the side of the power supply, a locking plate slidably connected to the surface of the rectangular plate, an arc groove formed on the surface of the locking plate, a spring fixedly connected to the top of the rectangular plate, a push plate fixedly connected to the other end of the spring, and the push plate being fixedly connected to the rectangular plate.

[0006] The effect achieved by the above components is as follows: under the action of the spring, the clamps are pressed together, thereby limiting the connection wires and preventing them from separating from the power supply, thus achieving the function of preventing detachment. When testing the brushless motor, the clamp is placed on the surface of the brushless motor's wires, the connection wires are connected to the power supply, the power is turned on, and the tester is powered on. The tester is adjusted by adjusting the knob, and then the brushless motor is tested.

[0007] Preferably, a washer, which is a rubber ring, is fixedly connected to the surface of the connection port on the side of the power supply.

[0008] The effect achieved by the above components is that, with the action of the washers, the connecting wires will not directly hit the side of the power supply, thus avoiding overload of the connecting wires.

[0009] Preferably, a magnetic block is fixedly connected to the side of the card plate, and the magnetic blocks are attracted to each other magnetically.

[0010] The effect achieved by the above components is that, under the action of the magnetic block, the plates can be locked together and fixed in place, thus preventing the plates from shifting.

[0011] Preferably, a circular strip is fixedly connected to the inner wall of the arc groove, and the interior of the circular strip is filled with gas.

[0012] The aforementioned components achieve the following effects: The circular bar prevents the arc groove from abrading the wire sheath, thus preventing damage. When connecting the wire to the power supply, pushing the push plate to both sides separates the locking plate. After inserting the wire into the power supply's connection port, releasing the push plate allows the locking plate to reset under spring pressure, causing the arc groove to lock onto the wire's surface. The circular bar again prevents the arc groove from abrading the wire sheath, preventing damage. The magnetic block ensures the locking plates are securely engaged, preventing displacement and thus preventing the wire from detaching.

[0013] Preferably, the surface of the detection line is provided with a storage device, the storage device including a rectangular frame disposed on the surface of the detection line, a bidirectional screw is rotatably connected inside the rectangular frame, and an L-shaped rod is threadedly connected to the surface of the bidirectional screw, the detection line being wound around the surface of the L-shaped rod.

[0014] The effect achieved by the above components is that, under the action of the bidirectional screw, the position of the L-shaped rod can be moved, thereby allowing the detection line to be taut on the surface of the L-shaped rod and avoiding loosening.

[0015] Preferably, the bottom of the rectangular frame is threaded with a bolt, and one end of the bolt is threaded onto the surface of a bidirectional threaded rod.

[0016] The effect achieved by the above components is that, under the action of the bolts, the position of the bidirectional screw is limited, thus preventing the bidirectional screw from rotating.

[0017] Preferably, an elastic clip is fixedly connected to the bottom of the rectangular frame, and the elastic clip is engaged with the surface of the detection line.

[0018] The effect achieved by the above components is that, under the action of the elastic clip, the rectangular frame can be fixed on the surface of the detection line, thereby facilitating the storage of the detection line.

[0019] Preferably, the inner wall of the elastic clip is fixedly connected with a clip bar, and the clip bar is evenly arranged inside the elastic clip.

[0020] The aforementioned components achieve the following effects: Under the action of the locking strip, the elastic clip is secured to the surface of the detection line, thus achieving a fixing effect. When it is necessary to store the detection line, the elastic clip is clamped onto the surface of the detection line, and under the action of the locking strip, the elastic clip is secured to the surface of the detection line, thus achieving a fixing effect. The detection line is wound around the surface of the L-shaped rod. After winding, the double-ended screw is turned by hand to move the L-shaped rod, thereby tightening the detection line and preventing it from loosening. After tightening, the bolt is screwed into the interior of the rectangular frame, so that one end of the bolt abuts against the surface of the double-ended screw for fixing, thus achieving the function of storing the detection line.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting an anti-detachment device, when it is necessary to connect the connecting cable to the power supply, the push plate is pushed to both sides to separate the locking plate. After the connecting cable is inserted into the connection port of the power supply, the force of pushing the push plate is released, and the locking plate is reset under the action of the spring. This causes the arc groove to lock onto the surface of the connecting cable. Under the action of the round bar, the arc groove will not wear the surface of the connecting cable, avoiding the phenomenon of damage to the surface of the connecting cable. Under the action of the magnetic block, the locking plate can be locked together, preventing the phenomenon of the locking plate shifting. This achieves the function of preventing the connecting cable from detaching, thus solving the problem that the connecting cable may fall off the connection port of the power supply when the tester is moved, resulting in no power supply.

A detection wire 6 is fixedly connected to the side of the tester 1, and a clip 7 is fixedly connected to one end of the detection wire 6. An adjustment knob 8 is provided on the surface of the tester 1 and the power supply 4, and an anti-detachment device 2 is provided on the surface of the power supply 4.

[0029] Working principle: When testing a brushless motor, clamp 7 is attached to the surface of the brushless motor's wires, connecting wire 5 is connected to power supply 4, and power supply 4 is turned on, energizing the tester 1. The tester 1 is adjusted by adjusting knob 8, thereby testing the brushless motor. The working principle of the brushless motor tester 1 mainly includes the following aspects:

[0030] Motor winding insulation performance test: Tester 1 tests the insulation performance of the motor windings to ensure that the motor will not be short-circuited or damaged due to insulation problems during operation.

[0031] Hall element fault diagnosis: Tester 1 can detect whether the Hall element is working properly, ensuring that the motor control system can accurately sense the rotor position.

[0032] Phase angle type identification: Tester 1 can identify whether the phase angle of the motor is 60 degrees or 120 degrees, which is very important for motor control and performance evaluation.

[0033] Brushless motor phase sequence verification: Tester 1 can verify whether the phase sequence of the motor is correct, ensuring that the motor can operate normally.

[0035] Phase matching degree test: Tester 1 tests the phase matching degree of the controller to ensure the stable performance of the motor under different loads and speeds.

[0036] Reference Figure 2The anti-detachment device 2 includes a rectangular plate 21 fixedly connected to the side of the power supply 4. A clamping plate 22 is slidably connected to the surface of the rectangular plate 21. An arc groove is formed on the surface of the clamping plate 22. A spring 23 is fixedly connected to the top of the rectangular plate 21. A push plate 24 is fixedly connected to the other end of the spring 23. The push plate 24 is fixedly connected to the rectangular plate 21. A washer 27, which is a rubber ring, is fixedly connected to the surface of the connection port on the side of the power supply 4. A magnetic block 25 is fixedly connected to the side of the clamping plate 22. The magnetic blocks 25 are attracted by magnetism. A round strip 26 is fixedly connected to the inner wall of the arc groove. The inside of the round strip 26 is filled with gas.

[0037] Working principle: When it is necessary to connect the connecting wire 5 to the power supply 4, push the push plate 24 to both sides to separate the clamping plate 22. After inserting the connecting wire 5 into the connection port of the power supply 4, release the force of pushing the push plate 24, so that the clamping plate 22 is reset under the action of the spring 23, thereby making the arc groove clamp onto the surface of the connecting wire 5. Under the action of the round bar 26, the arc groove will not wear the surface of the connecting wire 5, avoiding the phenomenon of damage to the surface of the connecting wire 5. Under the action of the magnetic block 25, the clamping plate 22 can be locked together, preventing the clamping plate 22 from shifting, thus achieving the function of preventing the connecting wire 5 from getting off.

[0038] Reference Figure 3 The surface of the detection line 6 is provided with a storage device 3, which includes a rectangular frame 31 on the surface of the detection line 6. A bidirectional screw 32 is rotatably connected inside the rectangular frame 31. An L-shaped rod 33 is threadedly connected to the surface of the bidirectional screw 32.

One end of the bolt 34 is threaded onto the surface of the bidirectional screw 32. An elastic clip 35 is fixedly connected to the bottom of the rectangular frame 31. The elastic clip 35 is clipped onto the surface of the detection line 6. A clip strip 36 is fixedly connected to the inner wall of the elastic clip 35. The clip strip 36 is evenly arranged inside the elastic clip 35.

[0039] Working principle: When it is necessary to store the detection line 6, the elastic clip 35 is clamped on the surface of the detection line 6. Under the action of the clip 36, the elastic clip 35 is clamped on the surface of the detection line 6, thereby achieving the function of fixing. The detection line 6 is wrapped around the surface of the L-shaped rod 33. After wrapping, the double-ended screw 32 is turned by hand to move the L-shaped rod 33, thereby tightening the detection line 6 and preventing it from loosening. After tightening, the bolt 34 is screwed into the interior of the rectangular frame 31, so that one end of the bolt 34 abuts against the surface of the double-ended screw 32 for fixing, thereby achieving the function of storing the detection line 6.
