Description

Technical Field

[0001] This invention belongs to the field of battery testing technology, specifically relating to a battery pack charging function testing system. Background Technology

[0002] In power tool manufacturing, battery pack charging function testing is a crucial test for ensuring battery pack compatibility and durability. It accurately simulates real-world charging scenarios for power tool battery packs. During testing, the device monitors key battery pack indicators in real time: whether it can charge to its rated capacity within a specified time, whether the cell temperature is abnormal during charging, and the sensitivity of charging protection under low and full charge conditions. Through these targeted tests, battery packs with substandard charging performance can be promptly eliminated, ensuring that the power tool battery packs leaving the factory have good compatibility with the tools, safe charging, and stable battery life.

[0003] Charging and vibration testing are two crucial tests related to the battery pack's reliability in actual use. However, current testing equipment in the industry often has limitations due to its single function, requiring separate dedicated equipment for charging and vibration testing. During testing, the battery pack is first placed in a charging test device to perform performance testing under charging conditions, and then transferred to a vibration test device to simulate performance under vibration. This separate testing approach not only requires multiple sets of equipment, increasing hardware costs and space requirements, but also prolongs the overall testing cycle and reduces efficiency due to the battery pack transfer during testing. More importantly, separate testing cannot simulate the real-world scenario of "charging while vibrating" in actual use, such as charging while a vehicle is in motion or charging while a power tool is vibrating during operation. This can lead to discrepancies between the test results and the actual performance of the battery pack in use, making it difficult to comprehensively and accurately assess the battery pack's reliability under complex operating conditions. Therefore, this paper proposes a battery pack charging function testing system. Summary of the Invention

[0014] As a further optimization of the present invention, the placement rack includes a cover plate with multiple placement slots. A base plate is fixedly disposed on the lower surface of the cover plate, and a slide rail is disposed on the base plate. A track is disposed on the mounting rack, and the slide rail is slidably disposed on the track. A transverse groove is disposed on the base plate, and a protrusion is slidably disposed in the transverse groove. A moving groove and a limiting hole are disposed on the base plate. The slide rail and the track enable the placement rack to move smoothly on the mounting rack.

[0015] As a further optimization of the present invention, the clamping mechanism includes a clamping plate, with connecting rods fixedly disposed at both ends of the clamping plate. The connecting rods are slidably disposed through the cover plate, and a connecting plate is disposed between the connecting rods. A spring is sleeved on the connecting rods, and the two ends of the spring are respectively connected to the cover plate and the connecting plate, thereby fixing the battery through the clamping mechanism.

[0016] As a further optimization of the present invention, the synchronous pulling mechanism includes a slide rod with multiple upright plates on it. The upright plates abut against the connecting plates. Wing plates are fixedly installed at both ends of the slide rod, and two horizontally arranged through slots are opened on the wing plates. Limiting bolts are provided on both sides of the placement frame and are inserted through the through slots. A second connecting rod is fixedly installed on the slide rod, and a handle is fixedly installed at the bottom of the second connecting rod.

This makes the operation convenient and avoids affecting the testing of other battery packs. Attached Figure Description

[0034] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content. Example

[0035] like Figure 1 - Figure 10 As shown, a battery pack charging function testing system includes a test cabinet 1 and an operation cabinet 2. The test cabinet 1 has a control cabinet 11, a servo motor 81 is fixedly installed inside the control cabinet 11, an output rod 82 is fixedly installed at the output end of the servo motor 81, and a control module 12 is installed inside the control cabinet 11. The test cabinet 1 has multiple mounting brackets 3, each with a fixed stand 31. Each stand 31 has multiple sockets 32, and each socket 32 ​​has a charger 33 installed on it. The control module 12 is electrically connected to the sockets 32 and the operation cabinet 2. A placement rack 4 is slidably installed on the mounting brackets 3. The operation cabinet 2 controls the test cabinet 1 through the control module 12 to obtain battery pack charging information in a timely manner. The control cabinet 11 provides a protective space for the servo motor 81 and the control module 12 to reduce external interference. Multiple mounting racks 3 can simultaneously test multiple battery packs, improving testing efficiency; multiple sockets 32 on the upright 31 can be connected to multiple chargers 33, adapting to simultaneous charging tests of multiple battery packs on the placement rack 4; the electrical connection between the control module 12 and the sockets 32 and the operating cabinet 2 enables real-time monitoring of charging parameters and rapid transmission of commands; when the operating cabinet 2 issues a command, the control module 12 can promptly control the power supply to the sockets 32, ensuring orderly testing; the control module 12 is connected to the servo motor 81, controlling the start / stop and speed of the servo motor 81 according to the commands issued by the operating cabinet 2; the sliding arrangement of the placement rack 4 on the mounting rack 3 provides a foundation for subsequent simulation of vibration environments.

[0036] like Figure 4 , Figure 5 and Figure 9As shown, the mounting frame 3 is equipped with an eccentric adjustment rotating mechanism 5, which includes a rotating disk 51. A sleeve 511 is fixedly mounted on the rotating disk 51. Synchronous pulleys 831 are fixedly mounted on both the output rod 82 and the sleeve 511. A synchronous belt 83 is provided between the synchronous pulleys 831. The rotating disk 51 is rotatably mounted on the mounting frame 3 via the sleeve 511. An adjustment component 52 is provided on the rotating disk 51. The adjustment component 52 includes a slide groove 521, which is fixedly mounted on the rotating disk 51. A lead screw 522 is rotatably mounted on the slide groove 521, and the lead screw 522 is threaded with... The slider 523 is slidably disposed in the slide groove 521. The slider 523 has a protrusion 53. A vertical shaft 524 is rotatably disposed in the sleeve 511. Both the vertical shaft 524 and the lead screw 522 are fixedly mounted with bevel gears 525, which mesh with each other. A knob is located at the lower end of the vertical shaft 524. The eccentric adjustment rotation mechanism 5 is the core for realizing vibration simulation and amplitude adjustment. The cooperation between the synchronous pulley 831 and the synchronous belt 83 stably transmits the power output from the servo motor 81 to the sleeve 511, ensuring the synchronicity and stability of the rotation of the rotating disk 51 and reducing power loss. The rotating disk 51 rotates on the mounting frame 3 via the sleeve 511, providing a rotational basis for subsequently moving the placement frame 4. The slide groove 521 guides and limits the sliding of the slider 523, preventing the slider 523 from deviating. The threaded engagement between the lead screw 522 and the slider 523 allows for precise adjustment of the slider 523's position by rotating the lead screw 522. The meshing of bevel gears 525 enables the power steering transmission between the vertical shaft 524 and the lead screw 522. The operator can easily drive the lead screw 522 to rotate by turning the knob at the lower end of the vertical shaft 524. No complicated operation is required, which is highly convenient. Furthermore, the vibration amplitude can be changed by adjusting the position of the protrusion 53 to meet the needs of different testing scenarios.

[0037] like Figure 4 - Figure 6 As shown, the placement rack 4 includes a cover plate 41 with multiple placement slots 411. A base plate 42 is fixedly mounted on the lower surface of the cover plate 41, and a slide rail 43 is fixedly mounted on the base plate 42. A track 431 is mounted on the mounting rack 3, and the slide rail 43 is slidably mounted on the track 431. A transverse groove 423 is formed on the base plate 42, and a protrusion 53 is slidably mounted in the transverse groove 423. The base plate 42 also has a moving groove 421 and a limiting hole 422. The cover plate 41 and the base plate 42 of the placement rack 4 form a stable structure. Multiple battery packs can be placed simultaneously in the multiple placement slots 411 to achieve batch testing. The sliding cooperation between the slide rail 43 and the track 431 makes the reciprocating movement of the placement rack 4 on the mounting rack 3 smoother and more stable, reducing frictional resistance during movement and ensuring the stability of vibration simulation. The cooperation between the transverse groove 423 and the protrusion 53 converts the circular motion of the rotating disk 51 into the reciprocating linear motion of the placement rack 4, which is a key connection structure for realizing vibration.

[0038] like Figure 6 As shown, the placement frame 4 is equipped with a clamping mechanism 6, which fixes the battery pack. The clamping mechanism 6 includes a clamping plate 61, with connecting rods 621 fixedly mounted at both ends of the clamping plate 61. The connecting rods 621 slide through and are mounted on the cover plate 41. A connecting plate 62 is provided between the connecting rods 621, and a spring 63 is sleeved on the connecting rods 621. The two ends of the spring 63 are connected to the cover plate 41 and the connecting plate 62, respectively. The clamping mechanism 6 can effectively fix the battery pack and prevent the battery pack from shaking during testing, thus avoiding affecting the test results. The clamping plate 61 is in direct contact with the battery pack and is fixed by fitting against both sides of the battery pack. The connecting rods 621 slide through and are mounted on the cover plate 41, providing guidance for the movement of the clamping plate 61 and ensuring the stability of the clamping plate 61's movement direction. The connecting plate 62 connects the two connecting rods 621 to achieve synchronous movement of the clamping plate 61; the elastic force of the spring 63 is the power for the clamping plate 61 to reset and clamp. When the synchronous pulling mechanism 7 releases the pull on the connecting plate 62, the spring 63 can quickly pull the connecting plate 62 to reset, causing the clamping plate 61 to clamp the battery pack. At the same time, the clamping plate 61, through the elastic action of the spring 63, cooperates with the placement groove 411 to adapt to different specifications of battery packs, improve the versatility of the device, and enhance the flexibility of clamping. Both the clamping plate 61 and the placement groove 411 are provided with sponge anti-slip pads to further fix the battery pack.

[0039] like Figure 5 - Figure 7As shown, the placement frame 4 is equipped with a synchronous pulling mechanism 7, which includes a slide rod 71. Multiple upright plates 711 are mounted on the slide rod 71, abutting against the connecting plate 62. Wing plates 72 are located at both ends of the slide rod 71, with two horizontally arranged through slots 721 on each wing plate 72. Limit bolts 722 are installed on both sides of the placement frame 4, passing through the through slots 721. A connecting rod 731 is fixedly mounted on the slide rod 71, with a handle 73 on it. The connecting rod 731 slides through the moving slot 421 onto the base plate 42. A limiting handle 74 is slidably mounted on the connecting rod 731. A second spring 75 is fitted onto the device, with its two ends connected to a handle 73 and a limiting handle 74, respectively. A limiting rod 741 is fixedly mounted on the limiting handle 74 and is embedded in a limiting hole 422. A moving groove 421 provides space for the movement of the connecting rod 731, while the limiting hole 422 is used to fix the position of the sliding rod 71 in conjunction with the limiting rod 741 of the limiting handle 74, ensuring the stability of the clamping mechanism 6. A clearance groove 34 is provided on the mounting frame 3, through which the handle 73 passes. The synchronous pulling mechanism 7 enables the simultaneous opening of multiple clamping mechanisms 6, eliminating the need to operate each clamping mechanism 6 individually, saving time for placing the battery pack and improving efficiency. Multiple upright plates 711 on the sliding rod 71 abut against the connecting plates 62 of each clamping mechanism 6. Pulling the sliding rod 71 will simultaneously pull multiple connecting plates 62 through the upright plates 711, thus enabling the clamping mechanisms 6 to open synchronously. The through slot 721 on the wing plate 72 cooperates with the limiting bolt 722 to provide guidance and limit for the movement of the slide rod 71, preventing the slide rod 71 from deviating during movement. The handle 73 facilitates the operator to pull the slide rod 71. The connecting rod 731 connects the handle 73 to the slide rod 71 and allows sliding through the moving slot 421. The limiting rod 741 on the limiting handle 74 is embedded in the limiting hole 422, which can fix the position of the slide rod 71 and keep the clamping mechanism 6 in the open state for easy placement of the battery pack. The spring 75 provides a return force for the limiting handle 74, which can quickly make the limiting rod 741 embed into the limiting hole 422 when the limiting handle 74 is released. The clearance slot 34 provides space for the movement of the handle 73 and prevents the mounting bracket 3 from obstructing the handle 73.

[0040] It should be noted that when the battery pack charging function testing system is working, the synchronous pulling mechanism 7 is operated first. By holding the handle 73 and the limiting handle 74, the slide rod 71 is pulled outward. The wing plates 72 at both ends of the slide rod 71 will move with it. At this time, the limiting bolts 722 slide in the through grooves 721 of the wing plates 72, providing guidance for the movement of the slide rod 71 and preventing it from deviating. The multiple upright plates 711 on the slide rod 71 will simultaneously abut against the connecting plates 62 of each clamping mechanism 6 and pull the connecting plates 62. The connecting plates 62 drive the connecting rods 621 at both ends to move. Since the connecting rods 621 are slidably mounted on the cover plate 41, they will drive the clamping plate 61 to move away from the placement groove 411. When clamp 61 moves to its final position, release the limiting handle 74. Under the elastic force of spring 75, the limiting handle 74 moves towards the base plate 42, causing the limiting rod 741 on the limiting handle 74 to engage with the limiting hole 422 on the base plate 42. This fixes the position of the sliding rod 71, keeping clamp 61 in the open state. Then, the battery pack to be tested can be placed in the multiple placement slots 411 of the cover plate 41. During placement, the battery pack can be placed in different slots 411 according to its size to ensure stable placement.

[0041] After placement, pull the limiting handle 74 away from the base plate 42 to compress the second spring 75, causing the limiting rod 741 to disengage from the limiting hole 422 and releasing the limitation on the slide rod 71. At this time, the spring 63 on the connecting rod 621 in the clamping mechanism 6 generates a restoring force due to the previous stretching. The two ends of the spring 63 are connected to the cover plate 41 and the connecting plate 62 respectively, which will pull the connecting plate 62 to reset. Then, the connecting rod 621 will drive the clamping plate 61 to move closer to the battery pack until the clamping plate 61 and the inner side of the placement groove 411 are tightly attached to both sides of the battery pack, thus fixing multiple battery packs firmly in the placement groove 411 at the same time and preventing the battery packs from shaking during the test.

[0042] After entering the testing phase, a start command is issued through the operation cabinet 2. The control module 12 receives the command and controls the drive mechanism 8 to run. The servo motor 81 of the drive mechanism 8 starts, and its output end drives the output rod 82 to rotate. The synchronous wheel 831 on the output rod 82 rotates with it. The power is transmitted to the synchronous wheel 831 on the sleeve 511 through the synchronous belt 83, thereby driving the rotating disk 51 to rotate around the sleeve 511 on the mounting frame 3. When the rotating disk 51 rotates, the protrusion 53 on it will slide in the circumferential direction in the transverse groove 423 of the base plate 42. Due to the cooperation between the protrusion 53 and the transverse groove 423, a reciprocating thrust will be generated on the base plate 42. The base plate 42 is slidably set on the track 431 of the mounting frame 3 through the slide rail 43. Under the action of the thrust, the entire placement frame 4 will move back and forth stably along the track 431 on the mounting frame 3, thereby generating vibration, which simulates the charging environment of the battery pack under vibration conditions such as vehicle bumps and transportation shaking.

[0043] Meanwhile, the socket 32 ​​on the upright frame 31 of the mounting bracket 3 is pre-connected to the charger 33, allowing the charging terminal of the charger 33 to be connected to the battery pack for charging. The control module 12 is located inside the control cabinet 11 of the test cabinet 1. It is electrically connected to the socket 32 ​​and the operation cabinet 2, respectively. It can monitor the charging parameters such as the output voltage and current of the charger 33 in real time, and transmit the monitoring data to the operation cabinet 2. The operator can check the charging status through the operation cabinet 2. If any abnormality occurs, the operator can promptly send a command to the control module 12 through the operation cabinet 2 to control the socket 32 ​​to cut off the power, etc., to ensure test safety.

[0044] If the vibration amplitude needs to be adjusted according to the testing requirements, it can be achieved by adjusting the eccentric adjustment rotation mechanism 5. In specific operation, rotating the knob at the lower end of the vertical shaft 524 causes the vertical shaft 524 to rotate within the sleeve 511. The bevel gear 525 at its upper end drives the bevel gear 525 on the lead screw 522 to rotate. Since the lead screw 522 is rotatably mounted in the groove 521 of the rotating disk 51, when the lead screw 522 rotates, the slider 523, which is threaded to it, slides along the groove 521. The protrusion 53 is fixedly mounted on the slider 523, thus changing the distance between the protrusion 53 and the center of the rotating disk 51. The farther the protrusion 53 is from the center, the greater the distance the placement frame 4 is pushed during rotation, resulting in a larger vibration amplitude; conversely, the closer the protrusion 53 is to the center, the smaller the vibration amplitude. This method allows for changing the vibration effect of different placement frames 4 to meet diverse testing needs.

[0045] If a battery pack malfunctions during testing and needs to be removed individually, there is no need to operate the synchronous pulling mechanism 7. Simply pull the clamping plate 61 of the corresponding clamping mechanism 6 outward. The clamping plate 61 drives the connecting rod 621 and the connecting plate 62 to move, compressing the spring 63 and separating the clamping plate 61 from the battery pack. Then, the single faulty battery pack can be easily removed from the placement slot 411. The operation is convenient and does not affect the testing of other battery packs.

[0046] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
