Description

Technical Field

[0001] This utility model belongs to the technical field of battery aging test equipment, specifically, it relates to a battery charge-discharge aging test equipment. Background Technology

[0002] In battery production and R&D, charge-discharge aging testing is a core component ensuring performance and safety. During long-term use, batteries experience aging phenomena such as capacity reduction and increased internal resistance due to factors like active material degradation, electrolyte decomposition, and changes in electrode structure. These changes directly affect the battery's range, charge-discharge efficiency, and safety. Charge-discharge aging testing simulates actual battery usage conditions, revealing potential defects early, such as insufficient cycle life and abnormal overheating during charge-discharge. This allows for the selection of qualified products, preventing substandard batteries from entering the market and causing equipment malfunctions and safety accidents. Furthermore, this test provides crucial data support for battery design improvements and material optimization, driving iterative upgrades in battery technology. However, existing testing equipment requires manual connection of the battery to the electrodes, which can easily lead to poor contact, affecting the accuracy of the test. It is also cumbersome and inefficient. After the test is completed, the batteries need to be removed one by one, which is labor-intensive and affects the efficiency of battery testing. In view of this, this utility model is proposed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a battery charge-discharge aging test device, which solves the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows: A battery charge-discharge aging test device, comprising: The worktable has two drive components and two gear plates mounted on it. The testing equipment includes a battery charge-discharge tester mounted on a workbench. The battery charge-discharge tester is electrically connected to a first electrode plate and a second electrode plate. The first electrode plate is mounted on the workbench, and the second electrode plate cooperates with two driving components. Two flipping components are provided, with a placement plate located between the two flipping components. Each flipping component includes a fixed plate, one side of which is rotatably fitted with a one-way gear and a rotating rod. A belt is used for transmission between the one-way gear and the rotating rod. The one-way gear meshes with a gear plate. One end of the rotating rod is elastic and rotatably fitted on a driving component. The placement plate has multiple placement holes and is fixedly connected between the two rotating rods.

[0005] Optionally, the first electrode plate is mounted on the upper side of the workbench, and multiple wires connect the first electrode plate and the second electrode plate to the battery charge and discharge tester. The first electrode plate is provided with multiple negative terminals, and the second electrode plate is provided with multiple positive terminals.

[0006] Optionally, the driving component includes a housing and a motor. A threaded rod is rotatably fitted inside the housing. The housing is mounted on a workbench, and the motor is mounted inside the housing. The output end of the motor is fixedly connected to the threaded rod, and the second electrode plate is threadedly fitted to the two threaded rods.

[0007] Optionally, a slider is slidably fitted on the threaded rod, a rotating rod is rotatably fitted on one side of the slider, a spring is installed between the slider and the motor, the spring is sleeved on the threaded rod, and a fixing plate is fixedly connected to one side of the slider.

[0008] Optionally, one side of the gear plate has a toothed surface and a smooth surface, and the one-way gear meshes with the toothed surface.

[0009] Optionally, a rotating shaft is rotatably fitted on one side of the fixed plate. The one-way gear includes a gear with an inner cavity. A ratchet is rotatably fitted inside the inner cavity. A locking block is rotatably fitted on one side of the inner wall of the inner cavity via a torsion spring. The locking block engages with the ratchet. The ratchet is fixedly connected to the rotating shaft. A belt drive is engaged between the rotating shaft and the rotating rod.

[0010] Optionally, the inner wall of the placement hole is elastically fitted with a first arc-shaped clamp and a second arc-shaped clamp on opposite sides.

[0011] Optionally, the placement plate has two control rods that slide together. One control rod has multiple first side plates installed on one side, and the other control rod has multiple second side plates installed on one side. The first side plates are elastically engaged with their adjacent first arc-shaped clamping plates, and the second side plates are elastically engaged with their adjacent second arc-shaped clamping plates.

[0012] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time: 1. The second electrode plate is moved by the set driving components (including the shell, motor and threaded rod), which squeezes the placement plate to move closer to the first electrode plate, so that the positive and negative terminals of the battery automatically contact the positive terminal of the second electrode plate and the negative terminal of the first electrode plate respectively (in conjunction with the wire to form a circuit). Compared with manual docking, it reduces the probability of poor contact, ensures the reliability of charge and discharge aging test data, and improves test efficiency. 2. After the test, the drive unit drives the second electrode plate to reset, and the placement plate retracts based on the elastic structure of the rotating rod (slider and spring). During this process, the one-way gear (including gear, ratchet, and locking block) of the flipping component meshes with the toothed plate and rotates. Through belt drive, the rotating rod drives the placement plate to rotate 180 degrees, and the battery in the placement hole is automatically discharged by gravity. There is no need to manually remove the battery from the placement hole one by one, which simplifies the operation process, reduces labor intensity, and accelerates the test cycle. 3. The one-way gear, through the cooperation of gears, ratchet, locking block and torsion spring, drives the rotating rod to rotate the placement plate to discharge material only when the placement plate is reset and retracted; when the placement plate moves to the first electrode plate for testing, the gear idles, and the ratchet and rotating shaft do not rotate, to ensure the battery posture is stable during the testing phase and to avoid the material discharge structure interfering with the test. 4. The first and second arc-shaped clamps on the inner wall of the placement hole, together with the control rod, the first side plate, the second side plate and the protrusion, when the placement plate moves towards the first electrode plate, the control rod is displaced by the action of the protrusion, pushing the arc-shaped clamps to move closer to the hole to clamp the battery, which enhances the stability of the battery during the test, prevents the battery from shifting due to equipment operation and electrode squeezing, and ensures the stability of the test.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] Please see Figure 1-5 As shown, this embodiment provides a battery charge-discharge aging test device, including: Workbench 1, on which two drive components 101 and two toothed plates 102 are installed; Testing device 2 includes a battery charge and discharge tester 201 installed on a workbench 1. The battery charge and discharge tester 201 is electrically connected to a first electrode plate 202 and a second electrode plate 203. The first electrode plate 202 is installed on the workbench 1, and the second electrode plate 203 cooperates with two driving components 101. Two flipping components 4, with a placement plate 3 located between the two flipping components 4. Each flipping component 4 includes a fixed plate 401. One side of the fixed plate 401 is rotatably fitted with a one-way gear 402 and a rotating rod 403. A belt 404 is connected between the one-way gear 402 and the rotating rod 403. The one-way gear 402 meshes with a toothed plate 102. One end of the rotating rod 403 is elastic and rotatably fitted on the driving member 101. Placement plate 3, which has multiple placement holes 301, is fixedly connected between two rotating rods 403.

[0019] The battery to be tested is placed into the placement hole 301 of the placement plate 3; the driving component 101 is activated, driving the second electrode plate 203 to move towards the placement plate 3. The second electrode plate 203 first contacts the positive terminal of the battery, and then continues to move and squeeze the placement plate 3, causing the placement plate 3 to move towards the first electrode plate 202 until the first electrode plate 202 contacts the negative terminal of the battery; at this time, the battery charge and discharge tester 201 forms a closed circuit with the battery using the first electrode plate 202, the second electrode plate 203, and the battery to perform charge and discharge aging tests; After the test, the drive component 101 drives the second electrode plate 203 to move in the opposite direction and reset, releasing the pressure on the placement plate 3; the placement plate 3 relies on the elastic structure of the rotating rod 403 to retract and reset. During the reset process, the one-way gear 402 in the flipping component 4 meshes with the toothed plate 102 and rotates. The rotating rod 403 is driven to rotate through the belt 404. The rotating rod 403 drives the placement plate 3 to rotate synchronously. When the placement plate 3 rotates 108 degrees, the battery that has completed the test in the placement hole 301 is discharged by gravity. The discharged battery can be picked up manually, and the next round of battery aging test can be carried out. The driving component 101 can move the second electrode plate 203, and the second electrode plate 203 can move the placement plate 3 towards the first electrode plate 202, so that the positive and negative terminals of the battery can contact the first electrode plate 202 and the second electrode plate 203, thereby reducing the possibility of poor contact, reducing frequent manual intervention, and improving testing efficiency. In addition, the flipping component 4 can automatically discharge the tested batteries after the battery test is completed, thereby saving the tedious task of manually removing the batteries one by one from the placement hole 301 and reducing the intensity of operation.

[0020] In this embodiment, the first electrode plate 202 is installed on the upper side of the workbench 1. The first electrode plate 202 and the second electrode plate 203 are connected to the battery charge and discharge tester 201 by multiple wires 204. The first electrode plate 202 is provided with multiple negative terminals 205, and the second electrode plate 203 is provided with multiple positive terminals.

[0021] The driving component 101 in this embodiment includes a housing 107 and a motor 103. A threaded rod 104 is rotatably fitted inside the housing 107. The housing 107 is mounted on the workbench 1. The motor 103 is mounted inside the housing 107. The output end of the motor 103 is fixedly connected to the threaded rod 104. The second electrode plate 203 is threadedly fitted to the two threaded rods 104. A slider 105 is slidably fitted on the threaded rod 104 in this embodiment. A rotating rod 403 is rotatably fitted on one side of the slider 105. A spring 106 is installed between the slider 105 and the motor 103. The spring 106 is sleeved on the threaded rod 104. A fixing plate 401 is fixedly connected to one side of the slider 105.

[0022] When the motor 103 starts, it will directly drive the threaded rod 104 to rotate. Since the second electrode plate 203 is threadedly engaged with the two threaded rods 104, the rotation of the threaded rod 104 will be converted into the linear movement of the second electrode plate 203 along the axial direction of the threaded rod 104, so as to realize the contact or separation of the second electrode plate 203 from the battery. Meanwhile, the slider 105, which is slidably engaged on the threaded rod 104, is connected to the motor 103 via a spring 106. The spring 106 is sleeved on the threaded rod 104, and the rotating rod 403 of the flipping assembly 4 is rotatably engaged on one side of the slider 105. The fixing plate 401 is fixed on the slider 105. When the second electrode plate 203 moves and presses the placement plate 3, the placement plate 3 will push the rotating rod 403 and the slider 105 to slide along the threaded rod 104 toward the motor 103. At this time, the spring 106 is compressed, providing elastic buffer for the slider 105. When the second electrode plate 203 is reset, the elastic force of the spring 106 will push the slider 105 to drive the rotating rod 403 and the placement plate 3 to retract, providing thrust for the action of the flipping assembly 4. The slider 105 provides rotational support for the rotating rod 403 and achieves elastic connection with the drive system through the spring 106, so that the drive component 101 can simultaneously drive the slider 105, the fixed plate 401 and other components of the flipping assembly 4 to move together while controlling the second electrode plate 203 to reset.

[0023] In this embodiment, the toothed plate 102 has a toothed surface and a smooth surface on one side, and the one-way gear 402 meshes with the toothed surface; the fixed plate 401 in this embodiment is rotatably fitted with a rotating shaft 405 on one side, the one-way gear 402 includes a gear 406, the gear 406 has an inner cavity, a ratchet 407 is rotatably fitted in the inner cavity, and a locking block 408 is rotatably fitted on one side of the inner wall of the inner cavity through a torsion spring. The locking block 408 cooperates with the ratchet 407, the ratchet 407 is fixedly connected to the rotating shaft 405, and the belt 404 is driven between the rotating shaft 405 and the rotating rod 403.

[0024] When the placement plate 3 returns to its original position under the action of the spring 106, the slider 105 drives the fixed plate 401 and the one-way gear 402 to move synchronously. At this time, the one-way gear 402 meshes with the tooth surface of the toothed plate 102, and the gear 406 rotates as it moves. Since the locking block 408 engages with the ratchet 407 under the action of the torsion spring, the rotation of the gear 406 will drive the ratchet 407 to rotate synchronously through the locking block 408, thereby causing the rotating shaft 405, which is fixedly connected to the ratchet 407, to rotate. The rotating shaft 405 is connected to the rotating rod 403 through the belt 404, which ultimately drives the rotating rod 403 and the placement plate 3 to rotate, realizing the discharge of the battery. When it moves to the smooth surface, the placement plate 3 returns to its original position. When the placement plate 3 moves toward the first electrode plate 202, the one-way gear 402 contacts the tooth surface of the tooth plate 102. At this time, the locking block 408 overcomes the torsion spring force and slides on the inclined side of the ratchet 407. The gear 406 rotates freely, and the ratchet 407 and the rotating shaft 405 do not rotate with it. The rotating rod 403 and the placement plate 3 remain stationary to avoid interfering with the battery posture during the test. The one-way gear 402 achieves one-way transmission function through the cooperation of gear 406, ratchet 407, locking block 408 and torsion spring; it drives the rotating rod 403 to rotate the placement plate 3 only when the placement plate 3 is reset and retracted, while it remains stationary during the testing phase (when the placement plate 3 is close to the electrode plate), controlling the timing and direction of the rotation of the placement plate 3 to ensure that the testing and material discharge actions do not interfere with each other.

[0025] In this embodiment, the inner walls of the placement hole 301 are elastically fitted with a first arc-shaped clamping plate 302 and a second arc-shaped clamping plate 303 on opposite sides. The placement plate 3 in this embodiment has two control rods slidably fitted inside. One control rod 304 has multiple first side plates 305 mounted on one side, and the other control rod 304 has multiple second side plates 306 mounted on one side. The first side plates 305 are elastically fitted with their adjacent first arc-shaped clamping plates 302, and the second side plates 306 are elastically fitted with their adjacent second arc-shaped clamping plates 303. Both outer shells 107 have protrusions on their opposite inner sides. The ends of the two control rods 304 extend out from both sides of the placement plate 3, and the extended ends are fitted with ball bearings that engage with the protrusions. When the placement plate 3 moves toward the first electrode plate 202, the placement plate 3 will synchronously drive the two control rods 304 to move together. During the movement, the two control rods 304 will contact the corresponding protrusions respectively, and after contact, they will be displaced by the action of the protrusions. At this time, the first side plate 305 and the second side plate 306 connected to the control rods 304 will move synchronously with the movement of the control rods 304, thereby pushing the first arc-shaped clamping plate 302 and the second arc-shaped clamping plate 303 to move closer to the inside of the placement hole 301, so as to realize the automatic clamping of the battery in the placement hole 301, thereby enhancing the stability of the battery in the placement hole 301.

[0026] It should be noted that all electrical devices involved in this application can be powered by batteries or external power sources.
