Description

Technical Field

[0001] This utility model relates to the field of battery testing technology, and in particular to a test device for battery impact resistance testing. Background Technology

[0002] A battery is a device that converts chemical energy into electrical energy. It contains an electrolyte solution and metal electrodes, forming a cup, tank, or other container or composite container that generates an electric current. It has a positive and a negative electrode. With technological advancements, the term "battery" now generally refers to any small device that generates electrical energy, such as a solar cell. The main performance parameters of a battery include electromotive force, capacity, specific energy, and resistance.

[0003] For example, CN2800499Y discloses a test device for battery impact resistance testing, including a hammer. The test device further includes a drop restraint device that holds the hammer and limits its vertical movement along the direction of gravity. This utility model's test device for battery impact resistance testing uses a drop restraint device to limit the vertical movement of the hammer along the direction of gravity, easily controlling the hammer's drop position, effectively improving the success rate of the test, and is easy to operate.

[0004] Existing test equipment for battery impact resistance testing places the battery inside the device. When the impact weight impacts the battery surface, it is easy for the impact weight to hit the battery corners due to improper battery placement, affecting the impact test structure. Moreover, the battery is also prone to misalignment due to impact during the test, and the battery position needs to be adjusted multiple times when multiple impacts are required.

[0005] Therefore, we propose a test apparatus for battery impact resistance testing. Utility Model Content

[0006] The purpose of this invention is to provide a testing device for battery impact resistance testing, aiming to solve the aforementioned technical problems.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model provides a testing device for battery impact resistance testing, including a test chamber. A door is rotatably mounted on one side of the test chamber, and the surface of the door is provided with transparent glass for observation. Inside the test chamber, there is a lifting screw and a moving arm. The moving arm can move up and down along the lifting screw. An electromagnetic block is mounted at the end of the moving arm, and an impact weight is attracted to the lower end of the electromagnetic block. Clamping structures are movably mounted on both sides of the lower end of the test chamber.

[0009] The clamping structure includes two movable clamping plates that can move relative to each other. Each movable clamping plate has two locking plates on opposite sides. The locking plates have mounting rods that pass through them. The mounting rods are fixedly connected to the clamping suction cups via mounting seats. The mounting seats and mounting rods have release structures inside them.

[0010] In some embodiments, the movable clamp is provided with a double-grooved screw inside, the adjusting seat is slidably mounted on the slide rod and connected to the surface of the double-grooved screw, the clamping plate is mounted on the adjusting seat, a second drive is installed at one end of the movable clamp and is drivenly connected to the double-grooved screw, and a contact sensor electrically connected to the second drive is provided on the side of the movable clamp facing the battery.

[0011] In some embodiments, a driver is fixedly installed at the upper part of the test chamber, and the driver is connected to the lifting screw drive.

[0012] In some embodiments, the clamping structure includes double-threaded sleeves, two of which are rotatably mounted on the bottom of the test chamber. The two double-threaded sleeves are connected to each other by a drive sprocket and a drive chain. A clamping screw is inserted into the end of each double-threaded sleeve, and a clamping rod is arranged parallel above the clamping screw. One end of each clamping rod is connected to the clamping screw, and the other end of the clamping rod passes through the side wall of the test chamber and is connected to a movable clamping plate inside the test chamber, forming two movable clamping plates that can move relative to each other.

[0013] In some embodiments, a bevel gear is fixedly fitted on the outer side of one of the double-threaded sleeves, and a first drive is fixedly provided in the middle of one side of the test box. The output end of the first drive extends to the test box and is equipped with a reversing gear, which meshes with the bevel gear.

[0014] In some embodiments, the detachment structure includes a vent groove located inside the mounting base, which connects the clamping suction cup to the outside. The vent groove also has an adjustment groove inside.

[0015] In some embodiments, a sealing block is movably installed inside the adjusting groove. The sealing block is connected to a piston block via an adjusting rod. The mounting rod has a movable groove inside. The piston block is disposed inside the movable groove and can slide along the movable groove. The sealing block is in contact with one end of the adjusting groove. A return spring is provided between the piston block and the end of the movable groove.

[0016] In some embodiments, an air pump is fixedly installed on one side of the movable clamp, and an air pipe is installed at the output end of the air pump, which is connected to the movable slot.

[0017] This utility model has the following beneficial effects:

[0018] 1. In this invention, the battery is placed at the lower end of the test chamber. The first drive, via a bevel gear and a reversing gear, rotates the double-threaded sleeves. The two double-threaded sleeves rotate synchronously under the action of the transmission sprocket and chain. The clamping screw, under the action of the thread, moves inwards towards the double-threaded sleeves. The clamping screw drives the clamping rod to move, which in turn drives the movable clamping plate to move, fixing the battery in the middle of the lower end of the test chamber, below the impact weight. When the movable clamping plate contacts the battery block, a contact sensor controls the second drive to operate. The second drive rotates the double-threaded screw, and the adjusting seat moves along the double-threaded screw, causing the clamping suction cup on one side of the clamping plate to engage with both sides of the battery block, further securing and limiting the battery block to prevent movement due to impact, thus facilitating battery testing. This invention can firmly fix the battery during impact testing, preventing displacement and enabling multiple consecutive impact tests.

[0019] 2. This utility model is equipped with a detachment structure, which uses an air pump to blow and control the air pressure in the fixed suction cup, thereby adjusting the suction force of the fixed suction cup and making it easier to remove the battery block.

[0020] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0031] like Figure 1 and Figure 2 As shown, the test apparatus for battery impact resistance testing provided in this embodiment includes a test chamber 1. A door 2 is rotatably mounted on one side of the test chamber 1, and the surface of the door 2 is provided with transparent glass for observation. A lifting screw 7 is provided on the inner wall of the test chamber 1, extending from the upper part to the lower part of the test chamber 1. One end of a moving arm 8 is mounted on the lifting screw 7, allowing the moving arm 8 to move up and down along the lifting screw 7. A driver 6 is fixedly mounted at the upper end inside the test chamber 1, and the driver 6 is connected to the lifting screw 7 to provide power to the lifting screw 7. An electromagnetic block 9 is provided at the other end of the moving arm 8, which can be positioned on the downward side of the moving arm 8. An impact weight 10 is attracted to the lower end of the electromagnetic block 9, and the impact weight 10 is used to impact the battery during the impact resistance test.

[0032] The bottom of the test box 1 is equipped with a clamping structure, and the clamping mechanism has two movable clamping plates 11 that can move relative to each other.

[0033] During testing, the battery is placed inside the test chamber 1. Under the action of the clamping structure, the battery is fixed between the movable clamping plates 11. The driver 6 drives the lifting screw 7 to rotate, and the moving arm 8 moves upward or downward inside the test chamber 1 under the action of the screw thread. The impact weight 10, under the action of magnetic force, comes into contact with the electromagnetic block 9, and the impact weight 10 is fixed on the electromagnetic block 9. Adjusting the driver 6 allows the impact weight 10 to be raised or lowered to different heights for testing.

[0034] Figure 3 As shown, the clamping structure includes double-threaded sleeves 12. Each double-threaded sleeve 12 has internal threads in two different directions at both ends. Two double-threaded sleeves 12 are installed inside the bottom of the test chamber 1, arranged in parallel and capable of rotating synchronously. Preferably, the two double-threaded sleeves 12 are interconnected via a drive sprocket and a drive chain. A clamping screw 4 is inserted into the end of each double-threaded sleeve 12. A clamping rod 5 is arranged parallel above the clamping screw 4. One end of each clamping rod 5 is connected to the clamping screw 4, and the other end of the clamping rod 5 passes through the side wall of the test chamber 1 and connects to a movable clamping plate 11 inside the test chamber, forming two relatively movable clamping plates 11. The movable clamping plates 11 are arranged perpendicular to the clamping rods 5.

[0035] The power of the double-threaded sleeve 12 is provided by the first drive 3. Specifically, a bevel gear is fixedly fitted on the outer side of one of the double-threaded sleeves 12. The first drive 3 is provided on one side of the test box 1. The output end of the first drive 3 extends to the bottom of the test box 1 and is equipped with a reversing gear. The reversing gear meshes with the bevel gear to transmit power.

[0036] In this embodiment, the battery is placed at the lower end inside the test chamber 1. The first drive 3 drives the double threaded sleeve 12 to rotate through the bevel gear and the reversing gear. The two double threaded sleeves 12 rotate synchronously under the action of the transmission sprocket and the transmission chain. The clamping screw 4 moves into the double threaded sleeve 12 under the action of the thread. The clamping screw 4 drives the clamping rod 5 and the two movable clamping plates 11 to move, fixing the battery in the middle of the lower end inside the test chamber 1, below the impact weight 10.

[0037] Figure 3 and Figure 4As shown, the test apparatus for battery impact resistance testing provided in this embodiment has two clamping plates 14 vertically arranged on opposite sides of the movable clamping plate 11. The clamping plates 14 are penetrated by a mounting rod 22. A mounting base 29 is fixedly installed at one end of the mounting rod 22. A clamping suction cup 15 is fixedly installed on one side of the mounting base 29. A double-threaded screw 19 is provided inside the movable clamping plate 11. Slide rods 20 are provided on both sides of the inner wall of the movable clamping plate 11. An adjusting seat 21 is arranged on the slide rod 20 and connected to the surface of the double-threaded screw 19. The clamping plates 14 are arranged on the adjusting seat 21. A second drive 16 is installed at one end of the movable clamping plate 11 and is drivenly connected to the double-threaded screw 19. A contact sensor 13 is provided on the side of the movable clamping plate 11 facing the battery and is electrically connected to the second drive 16. Preferably, the contact sensor 13 is located in the middle of the movable clamping plate 11.

[0038] The battery is placed between the movable clamping plates 11. When the movable clamping plates 11 contact the battery block, the contact sensor 13 controls the second drive 16 to operate. The second drive 16 drives the double-threaded screw 19 to rotate. The adjusting seat 21 moves the clamping plate 14 along the double-threaded screw 19, so that the clamping suction cup 15 on one side of the clamping plate 14 fits against the two sides of the battery block, which facilitates further clamping and limiting of the battery block. Due to the fixation of the four clamping suction cups 15 and the two movable clamping plates 11, the battery will not move when impacted by the heavy object 10.

[0039] In some implementations, such as Figure 4 and Figure 5 As shown, a release structure is provided inside the mounting base 29 and the mounting rod 22. The release structure includes a vent groove 26, which is located inside the mounting base 29 and connects the clamping suction cup 15 to the outside. An adjustment groove 27 is provided inside the vent groove 26, and a sealing block 28 is movably installed inside the adjustment groove 27. The sealing block 28 is connected to the piston block 23 via an adjustment rod 25. A movable groove is provided inside the mounting rod 22, and the piston block 23 is located inside the movable groove and can slide along it. The sealing block 28 is in contact with one end of the adjustment groove 27. A return spring 24 is provided between the piston block 23 and the end of the movable groove.

[0040] An air pump 17 is fixedly installed on one side of the movable clamping plate 11. An air pipe 18 is installed at the output end of the air pump 17 and is connected to the movable groove. The gas output from the air pump 17 can drive the piston block 23 to move.

[0041] When the battery needs to be removed, the air pump 17 operates, blowing air into the piston block 23 inside the movable slot through the air pipe 18. The piston block 23 moves inside the movable slot, and the piston block 23 drives the sealing block 28 to move through the adjusting rod 25, causing the sealing block 28 to disengage from one end of the adjusting slot 27. This allows air to enter between the clamping suction cup 15 and the battery block through the ventilation slot 26, reducing the gripping force of the clamping suction cup 15 and removing the battery block.

[0042] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
