Description

Technical Field

[0001] This utility model relates to the field of battery testing equipment, specifically to an electrode connection structure for a rapid battery capacity testing device. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It is widely used in various applications, from portable electronic devices to electric vehicles. It consists of one or more electrochemical units, each containing a positive electrode, a negative electrode, and an electrolyte. When a battery is connected to a load, a chemical reaction occurs between the electrodes. Ions are conducted through the electrolyte, while electrons flow through the external circuit, thereby generating an electric current. In engineering production, batteries need to pass multiple tests, such as those using battery capacity testing devices, before they can be sold. Battery capacity testing ensures the normal lifespan of the battery.

[0003] Existing battery capacity testing devices, also known as testing stations, estimate battery aging and capacity loss by measuring changes in the battery's internal resistance through an electrode connection structure. This method can be performed without complete charge-discharge cycles, resulting in shorter testing time, faster testing speed, and more accurate results compared to traditional full charge-discharge cycle testing. The existing electrode connection structure basically consists of a positive electrode connection block and a negative electrode connection block. The battery's internal capacity is tested by bringing these blocks into contact with the battery's positive and negative terminals. However, since both the positive and negative electrode connection blocks are bolted into the testing station, when testing new battery models, the spacing between the positive and negative terminals needs to be adjusted manually using tools to accommodate the new battery size. This increases the downtime for adjustment and reduces the testing efficiency to some extent. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides an electrode connection structure for a rapid battery capacity testing device. This solves the problem that requires operators to manually adjust the spacing between the positive and negative electrode connection blocks of the testing station using tools to accommodate new battery sizes. This increases the downtime for adjusting the testing station and reduces its testing efficiency to some extent.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrode connection structure for a rapid battery capacity testing device. This electrode connection structure is located inside a testing platform. Two telescopic cylinders are fixedly installed inside the testing platform, and their output ends are fixedly connected to the top of the electrode connection structure. The electrode connection structure includes a connecting assembly. Two support blocks are fixedly installed at the bottom of the connecting assembly. Triangular grooves are respectively formed on opposite sides of the two support blocks. Two triangular blocks are fixedly installed inside the testing platform, located on opposite sides of the two support blocks. The opposite sides of the two triangular blocks extend into the two triangular grooves, which are slidably connected. A positive electrode connection block is fixedly installed at the bottom of one support block, and a negative electrode connection block is fixedly installed at the bottom of the other support block.

[0006] As a preferred technical solution of this utility model, the connecting component includes a fixing block, which is disposed inside the testing table. The top of the fixing block is fixedly connected to the output ends of two telescopic cylinders. A T-shaped groove is provided at the bottom of the fixing block. Two T-shaped blocks are provided inside the T-shaped groove. The two T-shaped blocks are slidably connected to the T-shaped groove. The bottom of the two T-shaped blocks extends out of the T-shaped groove. The bottom of the two T-shaped blocks is fixedly connected to the top of two support blocks.

[0007] As a preferred technical solution of this utility model, a partition is fixedly provided inside the detection table, and the two sides of the partition extend into the interior of two support blocks respectively, and the outer surface of the partition is slidably connected to the inner surface of the two support blocks.

[0008] As a preferred technical solution of this utility model, the separator includes a trapezoidal block, which is located between two support blocks. The two support blocks have trapezoidal grooves on opposite sides, and the two sides of the trapezoidal block extend into the two trapezoidal grooves respectively. The trapezoidal block is slidably connected to the two trapezoidal grooves.

[0009] As a preferred technical solution of this utility model, a square block is fixedly provided at one end of the trapezoidal block, and the side of the square block away from the trapezoidal block is fixedly connected to the inside of the detection platform.

[0010] As a preferred technical solution of this utility model, the testing platform is provided with two clamps for clamping and limiting the battery. The bottom of the two clamps is slidably connected to the top of the testing platform. Limiting cylinders are respectively provided on the opposite side of the two clamps. The output end of the two limiting cylinders is fixedly connected to the opposite side of the two clamps.

[0011] Compared with the prior art, this utility model provides an electrode connection structure for a rapid battery capacity detection device, which has the following advantages:

[0012] Once the battery to be tested enters the testing station, the telescopic cylinder extends, driving the connecting assembly downwards. This, in turn, drives the two support blocks downwards. As the support blocks move downwards, the two triangular blocks contact the inclined surfaces of the two triangular slots. Driven by the triangular blocks, the inclined surfaces of the triangular slots on the two support blocks cause relative movement between them. Simultaneously, the two support blocks drive the positive and negative connection blocks to move until they connect to the positive and negative terminals of the battery. The equipment can then test the battery's capacity. This structure enables automatic adjustment of the spacing between the positive and negative connection blocks, eliminating the need for manual adjustment by operators. This reduces downtime for adjustments and improves the testing efficiency to some extent. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-6 In this embodiment: an electrode connection structure for a rapid battery capacity testing device is provided inside a testing platform 1. Two telescopic cylinders 2 are fixedly installed inside the testing platform 1, and their output ends are fixedly connected to the top of the electrode connection structure. The electrode connection structure includes a connecting assembly. Two support blocks 3 are fixedly installed at the bottom of the connecting assembly. Triangular grooves 4 are respectively formed on opposite sides of the two support blocks 3. Two triangular blocks 5 are fixedly installed inside the testing platform 1, located on opposite sides of the two support blocks 3, and extending into the two triangular grooves 4 on opposite sides. The component has two triangular blocks 5 slidably connected to two triangular grooves 4. One support block 3 has a positive electrode connection block 6 fixedly installed at its bottom, and the other support block 3 has a negative electrode connection block 7 fixedly installed at its bottom. The connecting component includes a fixing block 8, which is located inside the detection table 1. The top of the fixing block 8 is fixedly connected to the output ends of two telescopic cylinders 2. The bottom of the fixing block 8 has a T-shaped groove 9, and two T-shaped blocks 10 are provided inside the T-shaped groove 9. The two T-shaped blocks 10 are slidably connected to the T-shaped groove 9, and the bottoms of the two T-shaped blocks 10 extend out of the T-shaped groove 9. The bottoms of the two T-shaped blocks 10 are fixedly connected to the tops of the two support blocks 3.

[0022] The testing table 1 is fixedly provided with a partition, which extends into the interior of two support blocks 3 on both sides. The outer surface of the partition is slidably connected to the inner surface of the two support blocks 3. The partition includes a trapezoidal block 11, which is located between the two support blocks 3. Trapezoidal grooves 12 are respectively opened on the opposite side of the two support blocks 3. The two sides of the trapezoidal block 11 extend into the interior of the two trapezoidal grooves 12. The trapezoidal block 11 is slidably connected to the two trapezoidal grooves 12. A square block 13 is fixedly provided at one end of the trapezoidal block 11. The side of the square block 13 away from the trapezoidal block 11 is fixedly connected to the interior of the testing table 1.

[0023] The T-shaped block 10 limits the support block 3 through the T-shaped groove 9 of the fixing block 8, preventing the support block 3 from accidentally detaching from the connection with the trapezoidal block 11 and the triangular block 5, and ensuring the stability of the connection between the support block 3, the trapezoidal block 11, and the triangular block 5. The square block 13 is used to ensure the stability of the trapezoidal block 11 when it is located in the two trapezoidal grooves 12, and to avoid the trapezoidal block 11 from accidentally falling off.

[0024] The testing platform 1 is equipped with two clamps 14 for clamping and limiting the battery. The bottom of the two clamps 14 is slidably connected to the top of the testing platform 1. Limiting cylinders 15 are respectively provided on the opposite side of the two clamps 14. The output end of the two limiting cylinders 15 is fixedly connected to the opposite side of the two clamps 14.

[0025] After the equipment completes the capacity test of the battery, the two limit blocks drive the clamp 14 to retract, releasing the battery from the limit and allowing the battery to be removed from the test station 1. Then, the telescopic cylinder 2 retracts, driving the fixed block 8 to move upward. The fixed block 8 drives the two support blocks 3 to move upward through the two T-blocks 10. When the two support blocks 3 move upward, they will contact the trapezoidal block 11. The trapezoidal block 11 drives the two support blocks 3 to move in opposite directions through the inclined surface of the trapezoidal groove 12 of the two support blocks 3, causing the two support blocks 3 to reset. At the same time, the two support blocks 3 respectively drive the positive terminal connection block 6 and the negative terminal connection block 7 to reset.

[0026] The working principle and usage process of this utility model are as follows: When the battery to be tested enters the testing platform 1, two limiting cylinders 15 drive two clamps 14 to move relative to each other, thus clamping and limiting the battery placed inside the testing platform 1. The telescopic cylinder 2 extends, driving the fixing block 8 to move downward. The fixing block 8 drives the two support blocks 3 to move downward through the two T-blocks 10. When the two support blocks 3 move downward, the two triangular blocks 5 will contact the inclined surfaces of the two triangular grooves 4. Under the drive of the triangular blocks 5, the inclined surfaces of the triangular grooves 4 of the two support blocks 3 will move relative to each other. At the same time, the two support blocks 3 will drive the positive terminal connection block 6 and the negative terminal connection block 7 to move respectively, until the positive terminal connection block 6 and the negative terminal connection block 7 are connected to the positive and negative terminals of the battery. Then the device can test the battery capacity.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
