[0049] Reference Figure 2 , Figure 3 and Figure 5 , two mobile racks 10 are provided on the top of the test bench 6, and both of these mobile racks 10 can slide on the top of the test bench 6 to clamp the power equipment. In order to realize the clamping function, two first moving grooves 8 are provided on the top of the test bench 6, and a bidirectional screw rod 9 is rotatably connected in the two first moving grooves 8, and one end of the bidirectional screw rod 9 extends to one side of the test bench 6, so as to facilitate manual or electric driving of its rotation. A sliding seat threadedly connected to the bidirectional screw rod 9 is slidably connected in the two first moving grooves 8, and the two sliding seats are respectively located in the positive and negative thread sections of the bidirectional screw rod 9. Therefore, when the bidirectional screw rod 9 rotates, the two sliding seats will approach or move away from each other.

[0056] Reference Figure 2 , Figure 4 and Figure 8The switching structure also includes a first hydraulic chamber 40 arranged in the placing table 1. One end of the driving rod 35 extends into the first hydraulic chamber 40 and is fixed with a piston plate 41, which is sealed and slidable in the first hydraulic chamber 40. The universal ball 5 is provided with a second hydraulic chamber 42 and a plurality of hydraulic grooves connected to the second hydraulic chamber 42. Slide plates 43 are sealed and slidably connected in the plurality of hydraulic grooves, and the end of the slide plate 43 away from the second hydraulic chamber 42 is arc-shaped. The tops of the plurality of slide plates 43 all touch the bottom of the test bench 6, which is used to brake the universal ball 5 and the test bench 6. A connecting hose 44 is fixed to the inner wall of the bottom of the second hydraulic chamber 42, and the bottom end of the connecting hose 44 passes through the slide rod 4 and the fixed cylinder 2 in sequence, and extends into the first hydraulic chamber 40. The movement of the piston plate 41 can control the flow of hydraulic oil between the second hydraulic chamber 42 and the first hydraulic chamber 40, thereby controlling the extension and retraction of the slide plate 43.

[0057] When the driving rod 35 is engaged with the first worm 34, the driving rod 35 will push the piston plate 41 to inject hydraulic oil into the second hydraulic chamber 42, so that the slide plate 43 is extended, and the universal ball 5 and the test bench 6 are braked, so that the test bench 6 can be shaken up and down later. On the contrary, when the driving rod 35 is engaged with the second worm 33, the universal ball 5 and the test bench 6 are braked, so that the test bench 6 can be shaken later.

[0058] Reference Figure 2 and Figure 8 In this embodiment, the interior of the placing table 1 is designed with a second moving groove 45 that is interconnected with the transmission cavity 17. In the second moving groove 45, we slide and connect a lever 46, which can be rotatably sleeved around the outer wall of the driving rod 35. The main function of the lever 46 is to drive the driving rod 35 to move so that it can selectively engage with the second worm 33 or the first worm 34. In order to facilitate the operation of the lever 46, we fix a lever plate 48 on the top of the lever 46, and the lever plate 48 can slide on the top of the placing table 1. In addition, in order to maintain the stability of the lever 46 when it does not need to move, we fix magnets 47 on the inner walls on both sides of the second moving groove 45 that are away from each other, and fix iron sheets on both sides of the lever 46. In this way, the magnet 47 can generate a magnetic attraction on the lever 46 to achieve its positioning. When the lever 46 needs to be moved, it is only necessary to overcome the magnetic attraction of the magnet 47. In this way, we can easily drive the drive rod 35 to move through the shift plate 48 and the shift rod 46, and then control it to engage with the second worm gear 33 and the first worm gear 34 respectively, and the magnetic attraction of the magnet 47 to the shift rod 46 can keep the shift rod 46 stable when it does not need to move.

[0059] Reference Figure 2 and Figure 8In this embodiment, a driving motor 39 is fixed on one side of the placing table 1 through a frame. At the same time, a sleeve 38 is fixed on the end of the driving rod 35 away from the piston plate 41. The output shaft of the driving motor 39 can slide and extend into the sleeve 38, thereby driving the sleeve 38 and the driving rod 35 to rotate together. In this way, we can provide the required driving force for the shaking structure and the rocking structure.

[0060] Through the above implementation, a multifunctional comprehensive test of the electric equipment can be realized, including a bump test and a shake test, as well as braking and releasing during the test, so as to comprehensively evaluate the performance of the electric equipment.

[0061] Example 2: Reference Fig.10 and Fig.11 , improved on the basis of Example 1: We fixed a gantry 58 on the top of the placement table 1, and fixed a U-shaped plate 49 on the top of the gantry 58. On the inner walls of the two sides of the U-shaped plate 49 close to each other, we designed sliding grooves 52, and a sliding block 53 was slidably connected in each sliding groove 52. In order to drive the sliding block 53 to move, we fixed two electric push rods 54 on one side of the U-shaped plate 49, and the output shafts of the two electric push rods 54 respectively extended into the corresponding sliding grooves 52 and were fixedly connected to the corresponding sliding blocks 53. On the side where the two sliding blocks 53 are close to each other, we rotatably installed a rotating shaft 55, and the ends of the two rotating shafts 55 close to each other are fixed with the same spraying disc 50, which is located above the test bench 6 and is used to spray the electrical equipment below. At the top of the spraying disc 50, we designed an injection pipe 51, one end of which is connected to the external water pump, so that clean water can be injected into the spraying disc 50. In addition, a third gear 56 is fixedly mounted on the outer wall of each of the two rotating shafts 55, and two racks 57 are fixed on the inner wall of the corresponding side of the U-shaped plate 49, and the two racks 57 are respectively meshed with the bottoms of the two third gears 56. In this way, when the sliding block 53 moves, the rotating shaft 55 can be driven to reciprocate through the cooperation of the third gear 56 and the rack 57.

[0062] In actual use, we can first inject clean water from the outside into the spraying disc 50 through the water pump and the injection pipe 51, and then spray it on the power equipment below. In order to spray different angles of the power equipment, we can drive the sliding block 53 to move back and forth in the sliding groove 52 through the electric push rod 54. The movement of the sliding block 53 will drive the rotating shaft 55 to move together, and the rotating shaft 55 will reciprocate in the process of movement under the cooperation of the third gear 56 and the rack 57. In this way, we can spray the power equipment at different angles through the spraying disc 50.

[0063] A method for using a multifunctional power equipment comprehensive test system comprises the following steps:

[0064] S1. Place the power equipment on the top of the test bench 6, drive the two moving frames 10 to approach each other through the bidirectional screw rod 9, and the cooperation between the moving frame 10 and the step clamping block 11 clamps and fixes the power equipment. Under the action of the tension spring 15, the clamping plate 12 drives the plug-in end 13 to move toward the power equipment, and the plug-in end 13 is inserted into the interface of the power equipment to complete the docking of the power equipment, which is convenient for testing the operating status of the power equipment under different states in the later stage, and the corresponding clamping plate 12 and the plug-in end 13 can be replaced according to the interface of different power equipment;

[0065] S2. When it is necessary to simulate the operation of the electric equipment in a bumpy state, the driving rod 35 is driven to move toward the test bench 6 through the shift plate 48 and the shift rod 46, and the two cross rods 37 on the outer wall of the driving rod 35 move synchronously, and one of the cross rods 37 is disengaged from the cross groove 36, releasing the clamping connection between the driving rod 35 and the second worm 33. Similarly, the driving rod 35 completes the clamping connection between the driving rod 35 and the first worm 34 through the cross groove 36 and the cross rod 37, and the driving rod 35 pushes the piston plate 41 to move and squeezes the hydraulic oil into the second hydraulic chamber. 42, the slide plate 43 extends out under the action of the hydraulic oil and contacts the bottom of the test bench 6, thereby braking the universal ball 5 and the test bench 6, and then the driving motor 39 drives the driving rod 35 to rotate through the sleeve 38, and the driving rod 35 drives the first gear 20 to rotate through the cooperation of the first worm 34 and the first worm wheel 19, and the first gear 20 drives the first hemispherical block 22 to rotate through the inner gear ring 21, and the cooperation of the first hemispherical block 22 and the second hemispherical block 23 drives the test bench 6 to reciprocate up and down, completing the impact resistance test of the power equipment;

[0066] S3. When it is necessary to further test the load-bearing capacity and impact resistance of the power equipment, the driving rod 35 is driven to move in the opposite direction through the shift plate 48 and the shift rod 46, and the driving rod 35 is released from the clamping connection with the first worm 34 and completes the clamping connection with the second worm 33. The driving rod 35 drives the piston plate 41 to move, and the slide plate 43 can be retracted into the universal ball 5 again, and the brake between the universal ball 5 and the test bench 6 is released. Then the driving rod 35 drives the second worm wheel 26 and the second gear 27 to rotate through the second worm 33, and the second gear 27 is driven by the outer gear ring. 24 drives the L-shaped plate 28 to rotate, and the L-shaped plate 28 slides back and forth under the action of the L-shaped rod 31 and the track groove 32. When the L-shaped plate 28 moves back and forth, it continuously pulls the edge of the test bench 6 through the cooperation of the strip groove 30 and the pin rod 29. When the test bench 6 is pulled by the L-shaped plate 28, it tilts at a certain angle through the universal ball 5 and resets under the action of the reset spring 7. Therefore, with the rotation of the outer gear ring 24 and the L-shaped plate 28, the test bench 6 can continuously shake, thereby completing the load-bearing capacity and impact resistance test of the power equipment;

[0067] S4. When a waterproof test is required, the water pump injects clean water from the outside into the spray plate 50 through the injection pipe 51 and sprays it on the power equipment below. In order to spray the power equipment at different angles, the electric push rod 54 drives the sliding block 53 to move back and forth, and the sliding block 53 drives the rotating shaft 55 to move. When the rotating shaft 55 moves, it rotates back and forth with the cooperation of the third gear 56 and the rack 57, thereby driving the spray plate 50 to spray the power equipment at different angles.

[0068] However, as is well known to those skilled in the art, the working principles and wiring methods of the drive motor 39 and the electric push rod 54 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.

[0069] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
