Description

Technical Field

[0002] The automotive alternator is the vehicle's primary power source, responsible for supplying power to all electrical devices except the starter when the engine is running, and for charging the battery. Alternator testing is a complex and rigorous process, encompassing R&D, production, and quality control. The core objective is to ensure that it reliably, efficiently, and safely provides stable power to the vehicle under a variety of harsh conditions (high and low temperatures, vibration, humidity, salt spray, electrical interference, and sudden load changes), while also ensuring a sufficiently long service life. Performance (particularly rated output, idle output, and voltage stability), reliability (environmental resistance, vibration resistance, and long life), and safety (load dump protection and insulation) are paramount during testing.

[0003] In the existing technology, the site occupancy is reduced by centralizing the equipment for generator testing; adjusting the temperature in the high and low temperature control box and the speed of the motor can simulate the operation of the generator in different occasions, solving the problem of the generator needing to frequently change the field.

[0034] Specifically, the first motor 703 is turned on, and the rotation of the output shaft of the first motor 703 will drive the first gear 704 to rotate. Since the first gear 704 and the second gear 705 are engaged, the first gear 704 can rotate around the second gear 705, thereby driving the rotating ring 701 to rotate. The rotation of the rotating ring 701 can drive the fixed frame 706 to rotate and displace. As the rotating ring 701 rotates and displaces, the displacement block 708 can be driven to rotate and displace, thereby driving the third deflection seat 710, the support rod 711 and the fourth deflection seat 712 to rotate and displace, thereby driving the vibration plate 807 to rotate around the vibration rod 806.

The arc plate clamping mechanism 13 includes a clamping bracket 1301 fixed on the adjusting top plate 1105, the clamping bracket 1301 is threadedly connected to the feed thread rod 1302, and the end of the feed thread rod 1302 located outside the clamping bracket 1301 is fixedly connected to the rotating handle 1303, and the end of the feed thread rod 1302 away from the rotating handle 1303 is rotatably connected to the clamping plate 1304, the clamping plate 1304 and the clamping bracket 1301 are slidably connected, and the side of the clamping plate 1304 away from the feed thread rod 1302 is an arc structure.

[0036] Specifically, the generator 14 to be installed and tested is placed on the adjustment top plate 1105, and the rotating handle 1303 is held. The rotation of the rotating handle 1303 will drive the feed threaded rod 1302 to rotate, and the rotation of the feed threaded rod 1302 will drive the clamping plate 1304 to move along the clamping fixing frame 1301, and then drive the clamping plate 1304 to move downward, so that the arc-shaped side of the clamping plate 1304 is clamped on the surface of the generator 14 to achieve the clamping and fixing of the generator 14. At this time, if the generator 14 and the drive belt 1209 need to be connected, the mobile clamping sleeve 1207 is moved along the axial direction of the rotating shaft 1205, and the driving pulley 1208 can also move along the axial direction of the rotating shaft 1205 under the drive of the mobile clamping sleeve 1207. With the drive pulley 1208, This in turn drives the drive belt 1209 to move along the axial direction of the rotating shaft 1205, so that the drive belt 1209 is stuck on the generator 14. If the drive belt 1209 needs to be tensioned, the positioning bolt 1104 is screwed to remove the positioning bolt 1104 from the positioning hole 1103.

Since multiple arc plate clamping mechanisms 13 are provided, a specified number of generators 14 can be installed, thereby achieving synchronous testing of multiple generators 14.

[0037] In addition, when the generator 14 needs to be tested, the third motor 1201 is turned on, and the rotation of the output shaft of the third motor 1201 drives the drive shaft 1202. The rotation of the drive shaft 1202 can drive the first bevel gear 1203 to rotate. The rotation of the first bevel gear 1203 drives multiple second bevel gears 1204 to rotate. The rotation of the second bevel gear 1204 drives the rotating shaft 1205 to rotate. The rotation of the rotating shaft 1205 drives the movable card slot 1206 to rotate. The rotation of the movable card slot 1206 can drive the drive card strip therein to rotate. The rotation of the drive card strip drives the movable card sleeve 1207 to rotate. The rotation of the movable card sleeve 1207 drives the drive pulley 1208 to rotate. The rotation of the drive pulley 1208 drives the drive belt 1209 to rotate. As the drive belt 1209 rotates, the generator 14 is driven to realize the testing of the generator 14. As the generator 14 works, the status of the generator 14 can be monitored through the test signal collector 15.

[0038] The generator 14 is provided with a temperature sensor.

[0039] In an embodiment of the present invention, the radiation heat source 16 is turned on, and the radiation heat source 16 can generate heat. That is, the closer to the radiation heat source 16, the higher the temperature of the generator 14 will be. The specific working process is to turn on the first linear motor 9, and the first linear motor 9 can drive the lifting plate 10 to move up and down. As the lifting plate 10 moves up and down, the installation sleeve 1101 can be driven to move up and down. The installation sleeve 1101 can be driven to move up and down, and the side plate 1102 can be driven to move up and down. As the side plate 1102 moves up and down, the adjustment top plate 1105 can be driven to move up and down. As the adjustment top plate 1105 moves up and down, the generator 14 can be driven to move up and down, so as to control the distance between the generator 14 and the radiation heat source 16, thereby controlling the temperature of the generator 14.

[0040] Specifically, since the generator 14 is provided with a temperature sensor, the temperature of the generator 14 can be monitored, thereby accurately simulating the working state of the generator 14 .

[0041] Example 2, continue to refer to Figure 1-Figure 2 In the embodiment of the present invention, a fan 6 is provided on the side of the test box 1.

[0042] Specifically, by turning on the fan 6 , air can be blown from outside the test box 1 to inside, so as to achieve ventilation and cooling.

[0043] During the implementation of the present invention, the closed door 2 is first opened. At this time, the generator 14 to be tested is placed on the support and mounting frame mechanism 11, and then the generator 14 is clamped and fixed by the arc plate clamping mechanism 13. Then, the generator 14 is connected to the test signal collector 15, so as to collect the signal during the generator test. At this time, the connection between the generator 14 and the displacement drive belt mechanism 12 is realized, and the closed door 2 is closed. At this time, the convection ventilation mechanism 3 is opened, and the first linear motor 9 is turned on at the same time. The first linear motor 9 drives the lifting plate 10 to move upward, and the lifting plate 10 drives the support and mounting frame mechanism 11 to rise, thereby driving the generator 14 to rise, so that the generator 14 is close to the radiant heat source. 16. At this time, turning on the radiation heat source 16 can realize the heating of the generator 14, that is, simulating a cold start. After the cold start, the convection ventilation mechanism 3 is closed at this time, and the generator 14 will heat up quickly, thus simulating the starting state of hot operation. When the car is running, there will be air circulation. At this time, the convection ventilation mechanism 3 will be partially opened, and the fan 6 will be turned on at the same time, which can drive the air flow, thus simulating the normal operation of the generator 14. Turning on the rotating support mechanism 7 and the vibration rod mechanism 8 can drive the first linear motor 9 to vibrate randomly, and then drive the lifting plate 10 and the support mounting frame mechanism 11 to vibrate randomly, thereby driving the generator 14 to vibrate, thus simulating the vibration condition of the generator 14 during operation.

[0044] The present invention can achieve rapid ventilation and sealing of the test box 1 by setting a convection ventilation mechanism 3, thereby achieving heat gathering and rapid release, the test box 1 can be fixed by the positioning mechanism 4, the random vibration of the generator 14 can be achieved by the rotating support mechanism 7 and the vibration rod mechanism 8, thereby simulating the actual working condition of the generator installed on the car, the first linear motor 9 can drive the generator 14 to rise and fall, and control the distance between the generator 14 and the radiant heat source 16 to quickly adjust the temperature of the generator 14, and cooperate with the fan 6 to control the heat in the test box 1 and dissipate heat from the generator 14 at the same time, the arc plate clamping mechanism 13 can install and fix generators of different sizes, and the variable drive belt mechanism 12 can be installed and connected to generators 14 of different sizes, the real-time status of the generator 14 during the power generation process can be monitored by the test signal collector 15, and multiple arc plate clamping mechanisms 13 can achieve synchronous testing of multiple generators 14, thereby improving the efficiency of automobile generator testing.
