DETAILED DESCRIPTION

[0025] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following will be further described in detail in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model, and are not used to limit the utility model.

[0026] The utility model provides a kind of soft package battery pressurization formation charge-discharge device, its structure as shown in Figure 1 Figure 3 It includes two electrically-conductive clamp main body 1, fixing mechanism 2, detection mechanism 3 and charging mechanism 4.

[0027] The fixing mechanism 2 is used to fix battery.

[0028] The detection mechanism 3 is used to detect the thickness of battery and the number of tab.

[0029] The charging mechanism 4 includes double-sided charging plate 41, two single-sided charging plates 42 and first driving assembly 43 arranged on electrically-conductive clamp main body 1, the double-sided charging plate 41 is used to contact with the double-sided tab of battery, two single-sided charging plates 42 are located on the two sides of double-sided charging plate 41, and the first driving assembly 43 is used to drive two single-sided charging plates 42 to rotate to cover double-sided charging plate 41, so that two single-sided charging plates 42 contact with the single-sided tab of battery.

[0030] ​In use, the detection mechanism 3 detects the thickness of the battery and the number of tabs, according to the thickness of the battery, the main function of the fixing mechanism 2 is to ensure that the soft package battery is in a stable fixed state during the whole charging and discharging process. The double-sided charging plate 41 is arranged on the conductive clamp body 1, and the position and shape thereof are matched with the double-sided tabs of the battery. When the battery is fixed, the double-sided charging plate 41 is in close contact with the double-sided tabs of the battery, and a good conductive connection is formed. During charging, the charging power supply delivers electric energy to the double-sided charging plate 41 through the connecting line, and the current flows from the double-sided charging plate 41 into the double-sided tabs of the battery, and then into the battery, so that the charging process of the battery is realized. The two single-sided charging plates 42 are located on the two sides of the double-sided charging plate 41, and in the initial state, they are in the position not covering the double-sided charging plate 41. When charging the battery with single-sided tabs, the first driving assembly 43 starts to work. It drives the two single-sided charging plates 42 to rotate around the rotating shaft, gradually covers the double-sided charging plate 41, and the single-sided charging plate 42 is in contact with the single-sided tab of the battery. According to the charge conduction principle, the current can be conducted to the single-sided tab of the battery through the single-sided charging plate 42, so that the charging of the battery is realized.

[0031] In the utility model, when charging the battery with double-sided tabs, the tabs on the battery abut on the double-sided charging plate 41, when charging the battery with single-sided tabs, the first driving assembly 43 drives the single-sided charging plate 42 to rotate, the single-sided charging plate 42 covers the double-sided charging plate 41, the tabs on the battery are in contact with the single-sided charging plate 42, and the application range is wide.

[0032] In order to fix the battery, please refer to Figure 1 In a preferred embodiment, the fixing mechanism 2 comprises two pressing plates 21 and a second driving assembly 5, the two pressing plates 21 are respectively slidably connected to the two conductive clamp bodies 1, and the movable end of the second driving assembly 5 is connected to the pressing plate 21.

[0033] In use, when it is necessary to fix the soft package battery, the second driving assembly 5 drives the pressing plate 21 to slide towards the battery. With the movement of the pressing plate 21, it gradually approaches the battery and finally contacts the surface of the battery. According to the principle that friction is generated by pressure, the pressing plate 21 exerts a certain pressure on the battery, so that sufficient friction is generated between the pressing plate 21 and the battery.

[0034] In order to drive the pressing plate 21 to move, please refer to Figure 2In a preferred embodiment, the second driving assembly 5 comprises a power assembly 51, a first transmission assembly 52, and a second transmission assembly 53, the second transmission assembly 53 comprises two second connecting rods 531 arranged between the conductive clamp body 1 and the pressing plate 21, the two second connecting rods 531 are hinged together in the middle, one end of one second connecting rod 531 is fixedly connected to the conductive clamp body 1, the other end of one second connecting rod 531 is slidingly connected to the pressing plate 21 along the length direction of the pressing plate 21, one end of the other second connecting rod 531 is fixedly connected to the pressing plate 21, the other end of the other second connecting rod 531 is slidingly connected to the conductive clamp body 1 along the length direction of the conductive clamp body 1.

[0035] In use, the power assembly 51 transmits power to the second transmission assembly 53 through the first transmission assembly 52. The two second connecting rods 531 are hinged together in the middle, forming a structure similar to scissors. When power is transmitted to the hinge point, according to the principle of leverage and the principle of force decomposition, one second connecting rod 531 will exert a force on the other second connecting rod 531. One end of one second connecting rod 531 is fixedly connected to the conductive clamp body 1, and the other end is slidingly connected to the pressing plate 21 along the length direction of the pressing plate 21. When the power makes this second connecting rod 531 rotate around the fixed end, the end slidingly connected to the pressing plate 21 will exert a pushing force on the pressing plate 21 along the height direction of the pressing plate 21. At the same time, the other second connecting rod 531 has one end fixedly connected to the pressing plate 21 and the other end slidingly connected to the conductive clamp body 1 along the length direction of the conductive clamp body 1. The end slidingly connected to the conductive clamp body 1 will slide relative to the conductive clamp body 1 with the movement of the pressing plate 21, and this second connecting rod 531 will act as a support and guide for the pressing plate 21, ensuring that the pressing plate 21 moves along the height direction of the conductive clamp body 1. The coordinated movement of the two second connecting rods 531 makes the pressing plate 21 slide along the height direction of the conductive clamp body 1. With the sliding of the pressing plate 21, it will gradually approach the soft-pack battery. When the pressing plate 21 contacts the battery, according to the effect of force, the pressing plate 21 will exert pressure on the battery, thereby fixing the battery.

[0036] In order to transmit the force generated by the power assembly 51 to the second transmission assembly 53, please refer to Figure 2 In a preferred embodiment, the first transmission assembly 52 comprises two first sliding blocks 521 slidingly connected to the pressing plate 21 along the width direction of the pressing plate 21, the first sliding blocks 521 are hinged with first connecting rods 522, the other ends of the two first connecting rods 522 are hinged with a first sliding rod 523, the first sliding rod 523 is rotationally connected to the movable end of the second connecting rod 531, and the power assembly 51 is used to drive the two first sliding blocks 521 to slide in opposite directions.

[0037] In use, the power assembly 51 is used to drive the two first sliders 521 to slide reversely, and each first slider 521 is hingedly connected with a first connecting rod 522. When the first sliders 521 slide reversely, the first connecting rods 522 will change the angle with the movement of the first sliders 521. Since the two first sliders 521 slide reversely, the movement directions of the two first connecting rods 522 are opposite. The opposite movement makes the distance between the two first connecting rods 522 and the hinge points of the first slide bar 523 change, thereby generating a pulling force or a pushing force on the first slide bar 523, and the first slide bar 523 is rotationally connected to the movable end of the second connecting rod 531. When the first slide bar 523 is subjected to the force transmitted by the first connecting rod 522, it will transmit the force to the second connecting rod 531. Since the first slide bar 523 is rotationally connected, it can convert the direction of the force to a direction suitable for the movement of the second connecting rod 531.

[0038] In order to drive the two first sliders 521 to slide reversely, please refer to Figure 2 In a preferred embodiment, the power assembly 51 comprises a second motor 511 arranged on the pressing plate 21, and a double-headed screw rod 512 is arranged on the output shaft of the second motor 511, the double-headed screw rod 512 extends along the width direction of the pressing plate 21, and the two ends of the double-headed screw rod 512 respectively pass through and are threadedly connected with the two first sliders 521.

[0039] In use, the output shaft of the second motor 511 is connected with the double-headed screw rod 512, so the rotation of the output shaft will drive the double-headed screw rod 512 to rotate. When the double-headed screw rod 512 rotates, the two ends thereof are threadedly connected with the first sliders 521, thereby realizing the reverse sliding of the two first sliders 521 along the width direction of the pressing plate 21. The reverse sliding of the two first sliders 521 driven by the double-headed screw rod 512 will drive the first connecting rods 522 hingedly connected therewith to move.

[0040] In order to detect the thickness of the battery and the number of the tabs, please refer to Figure 1 In a preferred embodiment, the detection mechanism 3 comprises a photoelectric detector 31 arranged on the conductive clamp body 1, and the model of the photoelectric detector 31 is KG-PR-500M.

[0041] In use, the photoelectric detector 31 comprises a light emitting part and a receiving part. When detecting the thickness of the battery, the light emitting part emits light, usually visible light or infrared light, to the surface of the battery. The light travels in a straight line, based on the straight line propagation characteristics of light. When the light reaches the surface of the battery, reflection occurs. The path of the reflected light depends on the flatness and angle of the battery surface. The reflected light is received by the receiving part of the photoelectric detector 31. The round trip distance of the light propagation can be calculated by the time difference, and the distance from the battery surface to the detector is obtained. The photoelectric detector 31 images the battery tab part through the optical system. The optical system focuses the optical image of the tab on the light sensitive surface of the image sensor. The light sensitive elements convert the received light intensity signal into an electrical signal. Each light sensitive element corresponds to a pixel in the image, forming a digital image. Through feature extraction algorithms, such as extracting the shape, color, texture, etc. of the tab, the extracted features are matched with the pre-stored tab feature template. According to the matching result, the tab individuals in the image are identified, and the number of tabs is counted.

[0042] To drive the rotation of the single-sided charging plate 42, please refer to Figure 3 In a preferred embodiment, the first driving assembly 43 comprises a first motor 431 arranged on the conductive clamp body 1, and the output shaft of the first motor 431 is connected to one side of the single-sided charging plate 42.

[0043] In use, when the device needs to start the rotation of the single-sided charging plate 42, the first motor 431 starts to work after receiving the control signal. The output shaft of the first motor 431 is connected to one side of the single-sided charging plate 42, so when the motor rotor rotates, the output shaft will rotate together, thereby providing power for the rotation of the single-sided charging plate 42.

[0044] To avoid the battery with double-sided tabs from accidentally touching the single-sided charging plate 42, please refer to Figure 3 In a preferred embodiment, the conductive clamp body 1 is provided with two insulating plates 6, which are located on one side of the single-sided charging plate 42 and are rotatably connected to the conductive clamp body 1. The conductive clamp body 1 is provided with a third driving assembly 61, the movable end of which is connected to the insulating plate 6, and the third driving assembly 61 is used to drive the rotation of the insulating plate 6, so that the insulating plate 6 covers the single-sided charging plate 42.

[0045] In use, the movable end of the third driving assembly 61 is connected to the insulating plate 6. When it is necessary to drive the insulating plate 6 to rotate, the third driving assembly 61 starts to work after receiving the control signal. With the third driving assembly 61 driving the insulating plate 6 to rotate, the insulating plate 6 will gradually approach the single-sided charging plate 42. Then with the continuous rotation, the insulating plate 6 will gradually cover the single-sided charging plate 42 completely. This covering action can play a role in protecting the single-sided charging plate 42, and can also play a role in isolating and optimizing the charging environment, etc.

[0046] To drive the insulating plate 6 to rotate, please refer to Figure 3 In a preferred embodiment, the third driving assembly 61 comprises a third motor arranged on the conductive clamp body 1, and the output shaft of the third motor is connected to one side of the insulating plate 6.

[0047] In use, since the output shaft of the third motor is connected to one side of the insulating plate 6, the rotation of the rotor will drive the output shaft to rotate synchronously. With the rotation of the output shaft of the third motor, the insulating plate 6 will start to rotate around the connection point between the insulating plate 6 and the conductive clamp body 1.

[0048] To make the double-sided charging plate 41 adhere to the tab more tightly, please refer to Figure 3 In a preferred embodiment, a spring 411 is arranged between the double-sided charging plate 41 and the conductive clamp body 1, one end of the spring 411 is connected to the double-sided charging plate 41, and the other end of the spring 411 is connected to the conductive clamp body 1. When the single-sided charging plate 42 covers the double-sided charging plate 41, the spring 411 is in a compressed state.

[0049] In use, in the initial state, the spring 411 is connected between the double-sided charging plate 41 and the conductive clamp body 1, which provides a certain elastic force. In the absence of external force, the spring 411 is at a natural length or has a certain pre-tightening force, so that the double-sided charging plate 41 can maintain a good initial contact state with the double-sided tab of the soft pack battery. When the double-sided charging plate 41 is in contact with the battery tab, the elastic force of the spring 411 can ensure that the double-sided charging plate 41 tightly fits the tab to ensure good conductive performance. When the single-sided charging plate 42 starts to cover the double-sided charging plate 41 under the drive of the first drive assembly 43, the single-sided charging plate 42 will exert a pressure on the double-sided charging plate 41. Since the double-sided charging plate 41 is connected to the conductive clamp body 1 through the spring 411, this pressure will be transmitted to the spring 411. The spring 411 will be compressed and deformed under the action of this pressure. As the single-sided charging plate 42 gradually covers, the pressure continues to increase, and the compression of the spring 411 also gradually increases. The compression process of the spring 411 is a process of storing elastic potential energy, and at this time the elastic force of the spring 411 will balance the pressure exerted by the single-sided charging plate 42, so that the double-sided charging plate 41 can maintain a stable position during covering. When the spring 411 is in a compressed state, it stores elastic potential energy that will generate a reverse force on the double-sided charging plate 41. This force has two important functions, one is that when the single-sided charging plate 42 is removed, the spring 411 will use the stored elastic potential energy to quickly restore the double-sided charging plate 41 to the initial position, ensuring that the double-sided charging plate 41 can again normally contact the battery double-sided tab for charging. The second is that during the process of covering the double-sided charging plate 41 by the single-sided charging plate 42, the elastic force of the spring 411 can act as a buffer to avoid excessive impact force on the double-sided charging plate 41 by the single-sided charging plate 42, which can damage the double-sided charging plate 41 or affect its internal conductive structure, thereby prolonging the service life of the device, and also helps to maintain the stability of the device in different operating states.

[0050] In order to better understand the present application, the following will be combined with Figure 1 Figure 3 ​The working principle of the soft package battery pressurization formation charging and discharging device is described in detail as follows: the detection mechanism 3 detects the thickness of the battery and the number of the tabs, and according to the thickness of the battery, the main function of the fixing mechanism 2 is to ensure that the soft package battery is in a stable fixed state during the whole charging and discharging process. The double-sided charging plate 41 is arranged on the conductive clamp main body 1, and the position and shape thereof are adapted to the double-sided tabs of the battery. When the battery is fixed, the double-sided charging plate 41 is in close contact with the double-sided tabs of the battery, and a good conductive connection is formed. During charging, the charging power supply delivers electric energy to the double-sided charging plate 41 through the connecting line, according to the charge conduction principle, the current flows from the double-sided charging plate 41 into the double-sided tabs of the battery, and then enters the battery, so that the charging process of the battery is realized. The two single-sided charging plates 42 are located on the two sides of the double-sided charging plate 41, and in the initial state, they are in the position not covering the double-sided charging plate 41. When charging the battery with a single-sided tab, the first driving assembly 43 starts to work. It drives the two single-sided charging plates 42 to rotate around the rotating shaft, gradually covers the double-sided charging plate 41, and the single-sided charging plate 42 is in contact with the single-sided tab of the battery. According to the charge conduction principle, the current can be conducted to the single-sided tab of the battery through the single-sided charging plate 42, and the charging of the battery is realized.

[0051] The specific implementation mode of the utility model described above does not constitute a limitation on the protection scope of the utility model. Any various other corresponding changes and deformations made according to the technical concept of the utility model should be included in the protection scope of the utility model claim.
