[0002] In the production of electric tools, the battery pack charging function test is an important test for controlling the adaptability and durability of the battery pack. It can accurately simulate the actual charging scene of the battery pack of the electric tool. In the test, the device will monitor the core indicators of the battery pack in real time: whether it can be charged to the rated capacity within the specified time, whether the temperature of the battery cell is abnormal during charging, and whether the charging protection is sensitive under the conditions of low power and full power. Through these targeted tests, the battery pack with substandard charging performance can be timely eliminated to ensure that the battery pack of the electric tool leaving the factory has good adaptability with the tool, charging safety and stable endurance.

[0003] Charging test and vibration test are two important test items related to the actual use reliability. However, the test equipment in the industry often has the limitation of single function, and charging test and vibration test usually need to be carried out by different special equipment respectively. When testing, the battery pack needs to be placed in the charging test equipment to complete the performance detection under the charging state, and then it needs to be transferred to the vibration test equipment to simulate the performance under the vibration environment. This separate test method not only needs to be equipped with multiple sets of equipment, increasing the hardware cost and site occupation of the test, but also prolongs the overall test cycle and reduces the test efficiency due to the transfer operation of the battery pack in the test process.

[0022] ​As Figure 6 The placing rack 4 is provided with a clamping mechanism 6 for fixing the battery pack, the clamping mechanism 6 comprises a clamping plate 61, the two ends of the clamping plate 61 are fixedly provided with connecting rods one 621, the connecting rods one 621 are slidingly arranged on the cover plate 41, a connecting plate 62 is arranged between the connecting rods one 621, springs one 63 are sleeved on the connecting rods one 621, and the two ends of the springs one 63 are respectively connected with the cover plate 41 and the connecting plate 62. The clamping mechanism 6 can effectively fix the battery pack, so as to avoid the shaking of the battery pack during the test and affect the test result. The clamping plate 61 directly contacts the battery pack, and is fixed by being attached to the two sides of the battery pack. The connecting rods one 621 are slidingly arranged on the cover plate 41, which provides a guide for the movement of the clamping plate 61 and ensures the stability of the movement direction of the clamping plate 61. The connecting plate 62 connects the two connecting rods one 621, so as to realize the synchronous movement of the clamping plate 61. The elastic force of the springs one 63 is the power for the clamping plate 61 to reset and clamp. When the synchronous pulling mechanism 7 releases the pulling of the connecting plate 62, the springs one 63 can quickly pull the connecting plate 62 to reset, drive the clamping plate 61 to clamp the battery pack, and the clamping plate 61 can adapt to battery packs of different specifications by cooperating with the placing groove 411 through the elastic action of the springs one 63, so as to improve the versatility of the device and enhance the flexibility of clamping. The clamping plate 61 and the placing groove 411 are both provided with sponge anti-skid pads, so as to further fix the battery pack.

[0023] As Figure 5 - Figure 7As shown, the placing rack 4 is provided with a synchronous pulling mechanism 7, the synchronous pulling mechanism 7 comprises a slide rod 71, a plurality of vertical plates 711 are arranged on the slide rod 71, the vertical plates 711 abut against the connecting plates 62, wing plates 72 are arranged at both ends of the slide rod 71, two horizontally arranged through grooves 721 are formed in the wing plates 72, limiting bolts 722 are arranged on both sides of the placing rack 4, the limiting bolts 722 are arranged in the through grooves 721 in a penetrating manner, a connecting rod two 731 is fixedly arranged on the slide rod 71, a handle 73 is arranged on the connecting rod two 731, the connecting rod two 731 is arranged on the bottom plate 42 in a penetrating and sliding manner through a moving groove 421, a limiting handle 74 is arranged on the connecting rod two 731 in a sliding manner, a spring two 75 is arranged on the connecting rod two 731 in a sleeving manner, the spring two 75 is connected with the handle 73 and the limiting handle 74 at both ends respectively, a limiting rod 741 is fixedly arranged on the limiting handle 74, the limiting rod 741 is arranged in a embedded manner in a limiting hole 422, the moving groove 421 provides space for the movement of the connecting rod two 731, and the limiting hole 422 is used for cooperating with the limiting rod 741 of the limiting handle 74 to fix the position of the slide rod 71, so as to guarantee the stable state of the clamping mechanism 6, the mounting rack 3 is provided with an avoiding groove 34, the handle 73 penetrates the mounting rack 3 through the avoiding groove 34, and the synchronous pulling mechanism 7 is arranged to realize the synchronous opening of the plurality of clamping mechanisms 6, without the need of operating the clamping mechanisms 6 one by one, so that the time for placing the battery pack is saved and the efficiency is improved. The plurality of vertical plates 711 on the slide rod 71 abut against the connecting plates 62 of the clamping mechanisms 6, the slide rod 71 can be pulled to synchronously pull the plurality of connecting plates 62 through the vertical plates 711, so as to realize the synchronous opening of the clamping mechanisms 6. The through grooves 721 on the wing plates 72 cooperate with the limiting bolts 722 to provide guidance and limiting for the movement of the slide rod 71, so as to prevent the slide rod 71 from deviating when moving. The handle 73 is convenient for an operator to pull the slide rod 71, the connecting rod two 731 connects the handle 73 with the slide rod 71 and realizes sliding through the moving groove 421; the limiting rod 741 on the limiting handle 74 is arranged in the limiting hole 422 in an embedded manner, so as to fix the position of the slide rod 71 and keep the clamping mechanisms 6 in an open state, which is convenient for placing the battery pack; the spring two 75 provides a reset elastic force for the limiting handle 74, so that the limiting rod 741 can be quickly arranged in the limiting hole 422 when the limiting handle 74 is released; the avoiding groove 34 provides space for the movement of the handle 73, so as to avoid that the mounting rack 3 blocks the handle 73.

[0024] It should be noted that when the battery pack charging function test system is working, first operate the synchronous pulling mechanism 7, pull the slide rod 71 outward by holding the handle 73 and the limiting handle 74, the wing plates 72 at both ends of the slide rod 71 will move with it, at this time the limiting bolt 722 slides in the through slot 721 of the wing plate 72, providing guidance for the movement of the slide rod 71 to avoid deviation. The multiple vertical plates 711 on the slide rod 71 will be in contact with the connecting plate 62 of each clamping mechanism 6 and pull the connecting plate 62 at the same time, the connecting plate 62 drives the connecting rod one 621 at both ends to move, because the connecting rod one 621 is slidably arranged in the cover plate 41, so it will drive the clamping plate 61 to move away from the placement slot 411 side. When the clamping plate 61 moves to the final position, loosen the limiting handle 74, under the elastic force of the spring two 75, the limiting handle 74 moves to the bottom plate 42 direction, so that the limiting rod 741 on the limiting handle 74 is embedded in the limiting hole 422 of the bottom plate 42, so as to fix the position of the slide rod 71 and keep the opening state of the clamping plate 61. Then the battery packs to be tested can be placed in the multiple placement slots 411 of the cover plate 41 respectively, and they can be placed in different placement slots 411 according to the size of the battery pack to ensure stable placement.

[0025] After placement is completed, pull the limiting handle 74 away from the bottom plate 42, compress the spring two 75, and make the limiting rod 741 disengage from the limiting hole 422 to release the limiting of the slide rod 71. At this time, the spring one 63 on the connecting rod one 621 in the clamping mechanism 6 generates a restoring force due to being stretched before, the spring one 63 has both ends connected with the cover plate 41 and the connecting plate 62 respectively, which will pull the connecting plate 62 to reset, and then drive the clamping plate 61 to move towards the battery pack through the connecting rod one 621, until the clamping plate 61 tightly fits the battery pack on both sides of the inner side of the placement slot 411, so as to stably fix multiple battery packs in the placement slot 411, avoiding the battery pack from shaking during the test. After entering the test stage, the start command is sent by operating the cabinet 2, the control module 12 receives the command and controls the driving mechanism 8 to operate. The servo motor 81 of the driving mechanism 8 starts, and its output end drives the output rod 82 to rotate, the synchronous pulley 831 on the output rod 82 rotates with it, and the power is transmitted to the synchronous pulley 831 on the sleeve 511 through the synchronous belt 83, so as to drive the rotating disc 51 to rotate around the sleeve 511 on the mounting frame 3. When the rotating disc 51 rotates, the protrusion 53 on it will slide in the transverse groove 423 of the bottom plate 42 in the circumferential direction, and due to the cooperation of the protrusion 53 and the transverse groove 423, a reciprocating thrust will be generated on the bottom plate 42. The bottom plate 42 is slidably arranged on the track 431 of the mounting frame 3 through the slide rail 43, and under the thrust, the placement frame 4 will stably move back and forth on the mounting frame 3 along the track 431, and then vibrate, so as to simulate the charging environment of the battery pack under the vibration conditions such as vehicle bumping and transportation shaking. At the same time, the socket 32 on the stand 31 in the mounting frame 3 is pre-connected with the charger 33, and the charging end of the charger 33 can be connected with the battery pack to charge the battery pack. The control module 12 is arranged in the control cabinet 11 of the test cabinet 1, and is electrically connected with the socket 32 and the operation cabinet 2 respectively, so as to monitor the output voltage, current and other charging parameters of the charger 33 in real time, and transmit the monitoring data to the operation cabinet 2. The operator can check the charging state through the operation cabinet 2, and if an abnormality occurs, the operator can send an instruction to the control module 12 through the operation cabinet 2 to control the socket 32 to be powered off, so as to ensure the test safety. If it is necessary to adjust the vibration amplitude according to the test requirement, the eccentric adjustment rotating mechanism 5 can be adjusted. In the specific operation, the knob at the lower end of the vertical shaft 524 is rotated, the vertical shaft 524 is rotated in the sleeve 511, the bevel gear 525 at the upper end of the vertical shaft 524 drives the bevel gear 525 on the lead screw 522 to rotate, the lead screw 522 is arranged in the sliding groove 521 of the rotating disc 51, and when the lead screw 522 rotates, the sliding block 523 connected with the lead screw 522 through the screw thread will slide along the sliding groove 521, and the lug 53 is fixedly arranged on the sliding block 523, so that the distance between the lug 53 and the center of the rotating disc 51 changes. When the lug 53 is farther away from the center, the distance pushed by the placement frame 4 during rotation is greater, and the vibration amplitude is greater. Conversely, the vibration amplitude is smaller. In this way, the vibration effect of different placement frames 4 can be changed to meet the diversified test requirements. If a battery pack is found to be faulty during the test and needs to be taken out alone, the synchronous pulling mechanism 7 does not need to be operated, and the clamping plate 61 of the corresponding clamping mechanism 6 can be directly pulled outwards. The clamping plate 61 drives the connecting rod one 621 and the connecting plate 62 to move, compresses the spring one 63, and separates the clamping plate 61 from the battery pack. Then, a single faulty battery pack can be easily taken out from the placement groove 411, and the operation is convenient and does not affect the test of other battery packs.
