[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The present invention is provided with a clamping mechanism and a charging mechanism.

Therefore, when the charging interface is charged, different types of batteries in the first installation slot can be charged, thereby improving the adaptability of charging.

[0022] 2. The present invention provides a fourth limiting slot and a slider. On the one hand, when the battery is installed, the slider can be driven to move in the fourth limiting slot in a direction away from the fixed part by moving the movable part, and move to a position corresponding to the first conductive connector. The battery is then inserted into the first installation slot, so that the first conductive connector is connected to the positive electrode sheet of the battery, and then the moved second conductive connector is connected to the negative electrode sheet of the battery to form a pathway for charging. On the other hand, when the slider moves in the fourth limiting slot, the limiting card can cooperate with the two adjacent protrusions to limit the slider from stopping. Therefore, the position of the positive electrode sheet can be adjusted by moving the slider, thereby improving the adaptability of the battery to other devices. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] like Figure 3 As shown, a telescopic tube 420 is connected between the movable part 31 and the mounting part 41, a first guide groove 421 connected to the telescopic tube 420 and the first accommodating groove 33 is provided inside the movable part 31, a first one-way valve 422 is provided at the connection between the first guide groove 421 and the telescopic tube 420, a second one-way valve 423 is provided inside the first accommodating groove 33, an air inlet groove 424 connecting the two third limiting sliding grooves 415 is provided inside the adjusting part 410, a second guide groove 425 connected to the air inlet groove 424 and the telescopic tube 420 is provided inside the mounting part 41, and a second air guide groove 426 that can be connected to the accommodating cavity 411 and the air inlet groove 424 is provided inside each sliding part 416.

[0056] In a normal state, the second piston plate 412 is located at one side of the accommodating chamber 411. At this time, the sliding member 416 on this side can be squeezed by the second piston plate 412 into the corresponding third limiting sliding groove 415, so that the second air guide groove 426 on the sliding member 416 on this side corresponds to and communicates with the air inlet groove 424, and the sliding member 416 on the other side can be squeezed by the gas in the regulating chamber 417 to move toward the second piston plate 412, so that the first air guide groove 419 on the sliding member 416 on this side can be communicated with the exhaust port 418. For example, when the second piston plate 412 is located on the right side of the accommodating chamber 411, the sliding member 416 on the right side 6 can be squeezed into the corresponding third limiting groove 415 by the second piston plate 412, so that the second air guide groove 426 on the right sliding member 416 can correspond to and communicate with the air inlet groove 424, so that the first air guide groove 419 on the right side and the exhaust port 418 are misaligned, and the sliding member 416 on the left side can be squeezed by the gas in the adjustment chamber 417 to move toward the direction close to the second piston plate 412, so that the first air guide groove 419 on the left sliding member 416 can correspond to and communicate with the exhaust port 418, so that the second air guide groove 426 on the left side and the air inlet groove 424 are misaligned, so that the gas entering the interior of the telescopic tube 420 can pass through the second The guide groove 425 and the air inlet groove 424 enter the right side of the second air guide groove 426, which can push the second piston plate 412 to move to the left, and can squeeze the gas on the left side of the accommodating chamber 411 to be discharged from the exhaust port 418 on this side to the inside of the second mounting groove 42, so as to perform air blowing and heat dissipation. When the second piston plate 412 is about to move to the left limit position, the second piston plate 412 will squeeze the left sliding member 416 into the corresponding third limiting sliding groove 415, so that the second air guide groove 426 on the left sliding member 416 corresponds to and is connected with the air inlet groove 424, so that the first air guide groove 419 on the left side is connected with the exhaust port 418 on the left side. 418 is misaligned, which can make the first air guide groove 419 on the right sliding member 416 correspond to and be connected with the exhaust port 418, and make the second air guide groove 426 on the right side misaligned with the air inlet groove 424. At this time, the gas entering the telescopic tube 420 can enter the left side of the second air guide groove 426 through the second guide groove 425 and the air inlet groove 424, which can make the second piston plate 412 move to the right side, and can squeeze the gas on the right side of the accommodating chamber 411 to be discharged from the exhaust port 418 on this side to the inside of the second mounting groove 42 for blowing and heat dissipation, thereby realizing the reciprocating movement of the second piston plate 412 in the accommodating chamber 411.

[0057] The gas inside the first receiving groove 33 can enter the interior of the telescopic tube 420 through the first one-way valve 422, and the external gas can enter the interior of the first receiving groove 33 through the second one-way valve 423, that is, when the limit assembly 35 and the first piston plate 34 move in the direction close to the first installation groove 32 inside the first receiving groove 33, the external gas can be drawn into the interior of the first receiving groove 33.

[0058] When inserting the battery into the first mounting groove 32, the battery will preferentially contact the wedge-shaped surface at the bottom of the limiting assembly 35, which will squeeze the limiting assembly 35 and the first piston plate 34 to move in the first receiving groove 33 in a direction away from the first mounting groove 32. The third elastic member 314 is compressed, and the first piston plate 34 can squeeze the gas in the first receiving groove 33, so that the gas enters the interior of the telescopic tube 420 through the first one-way valve 422. When the battery is fully inserted into the first mounting groove 32, the third elastic member 314 will be elastically reset, which can drive the limiting assembly 35 to move closer to the first mounting groove 33. 2, the extrusion plate 37 will contact the outer side of the bottom of the battery, so that the extrusion plate 37 can move in the direction close to the first piston plate 34 inside the second limiting slide groove 36, squeezing the first elastic member 38, and the battery can be clamped and fixed by the extrusion plate 37 and the inner wall of the first mounting groove 32 to prevent movement. When the extrusion plate 37 moves in the direction close to the first piston plate 34, the limiting assembly 35 in the resetting can be misaligned with the extrusion plate 37, and the bottom of the battery can contact the limiting assembly 35, which can support the battery and prevent the battery from moving downward, thereby realizing the installation and fixation of batteries of different models.

When the second piston plate 412 moves inside the accommodating chamber 411, the magnet 414 can drive the iron core 434 to move synchronously through magnetic force.

[0060] The first conductive member 43 and the second conductive member 44 are both disposed below the adjustment component 49 and have the same height. The first conductive member 43 and the second conductive member 44 are staggered on the same plane to avoid interference between the second conductive connector 47 and the first conductive connector 45 when the second conductive connector 47 moves.

A clamping piece 439 fixedly connected to the movable plate 437 is slidably connected inside each of the first limiting grooves 438. When the movable plate 437 moves in the direction close to the iron core 434 inside the movable groove 435, the clamping piece 439 can clamp the second conductive piece 44 through the limiting plate 431.

[0062] The bottom of the sliding bin 430 is fixedly connected to the second fixed bin 440, the interior of the second fixed bin 440 is slidingly connected to the second contact 441, a fifth elastic member 442 is connected between the top of the second contact 441 and the inner wall of the second fixed bin 440, one end of the coil 433 is electrically connected to the second contact 441, and the other end of the coil 433 is electrically connected to the second conductive member 44, when current flows through the coil 433, the iron core 434 can generate magnetism.

[0063] When the iron core 434 generates magnetic force, the top magnetic pole of the iron core 434 repels the bottom magnetic pole of the magnet 414. At this time, the magnet 414 cannot drive the iron core 434 to move through the magnetic force. That is, when the iron core 434 generates magnetic force, when the top of the iron core 434 is the N pole, then the bottom of the magnet 414 should also be the N pole. Like poles repel each other, and opposite poles attract each other.

[0064] It should be noted that in actual use, the battery is quickly inserted into the first mounting groove 32 so that the first conductive connector 45 is connected to one of the electrodes of the battery. During this process, the battery will preferentially contact the wedge-shaped surface at the bottom of the limiting assembly 35, which will squeeze the limiting assembly 35 and the first piston plate 34 to move inside the first accommodating groove 33, so that the third elastic member 314 is compressed. The first piston plate 34 can squeeze the gas inside the first accommodating groove 33, and the gas enters the interior of the telescopic tube 420 through the first one-way valve 422, and enters the interior of the second air guide groove 426 through the second guide groove 425 and the air inlet groove 424, so that the second piston plate 412 can move inside the accommodating chamber 411, for example, from right to left, and can drive the iron core 434 to move synchronously through the magnetic force of the magnet 414, thereby bringing The second conductive connector 47 moves in the same direction in the second mounting groove 42, so that the moving second conductive connector 47 is connected to the other electrode of the battery to form a path, so that current flows through the coil 433, which can make the iron core 434 generate magnetism. The top magnetic pole of the iron core 434 repels the bottom magnetic pole of the magnet 414, so that the magnet 414 cannot drive the iron core 434 to move by magnetic force. At the same time, the magnetism of the iron core 434 will attract the iron ring 436 to move upward, driving the movable plate 437 to move in the direction close to the iron core 434 inside the movable groove 435, and the clamping member 439 and the limiting plate 431 can clamp and fix the second conductive member 44 to prevent the second conductive connector 47 from moving as a whole. Therefore, when the charging interface 21 is charged, the battery inside the first mounting groove 32 can be charged.

[0065] When the battery is fully charged, the operator first removes the mounting shell 2 from the battery shell 1, and then presses the moving block 312 to move inside the second receiving groove 39, so that the pressing rod 311 contacts the wedge-shaped surface at the bottom of the limiting component 35, so that the limiting component 35 is squeezed into the first receiving groove 33, so that the squeezing plate 37 slowly disengages from the clamping of the battery, and the limiting component 35 no longer supports the battery, so that the battery falls under the action of gravity, thereby realizing the disassembly of the battery. In this process, the first piston plate 34 also squeezes the gas inside the first receiving groove 33, and the gas passes through The first one-way valve 422 enters the interior of the telescopic tube 420, and enters the interior of the second air guide groove 426 through the second guide groove 425 and the air inlet groove 424, which can enable the second piston plate 412 to move inside the accommodating chamber 411. If the second piston plate 412 moves from right to left when the battery is installed, then the second piston plate 412 will move from left to right during this process. The purpose is to allow the magnet 414 to drive the second conductive connector 47 that has been powered off to return to the position before the battery is installed through the moving second piston plate 412, so as to facilitate the subsequent adjustment and use of the battery installed here.

[0066] The present invention is provided with the clamping mechanism 3 and the charging mechanism 4. During use, the battery is quickly inserted into the first installation groove 32, so that the first conductive connector 45 is connected to one of the electrodes of the battery. During this process, the battery will preferentially contact the wedge-shaped surface at the bottom of the limiting component 35. The first piston plate 34 can squeeze the gas inside the first receiving groove 33. The gas enters the second gas guide groove 426 through the telescopic tube 420, which can make the second piston plate 412 move inside the receiving cavity 411. The magnetic force of the magnet 414 can drive the iron core 434 to move synchronously, and can drive the second conductive connector 47 to move in the second installation groove 42, so that the second conductive connector 47 is connected to the other electrode of the battery. When the first and second conductive members 434 are connected, current will flow through the coil 433, which can make the iron core 434 generate magnetism. The top magnetic pole of the iron core 434 repels the bottom magnetic pole of the magnet 414, so that the magnet 414 cannot drive the iron core 434 to move through the magnetic force. At the same time, the magnetism of the iron core 434 will attract the iron ring 436 to move upward, and can drive the movable plate 437 to move in the direction close to the iron core 434 inside the movable groove 435, so that the clamping member 439 and the limiting plate 431 can clamp and fix the second conductive member 44 to prevent the second conductive connector 47 from moving as a whole. Therefore, when the charging interface 21 is charged, it is possible to charge batteries of different types in the first mounting slot 32, thereby improving the adaptability of charging.

[0067] Embodiment 2

[0068] On the basis of the above-mentioned embodiment, since the batteries of existing handheld devices are not universal and the positive and negative electrodes of the batteries are often unable to move, the positions of the positive and negative electrodes on batteries of different models are different, resulting in one of the electrodes of the battery being unable to align and contact with the first conductive connector 45 when the battery is installed in the card connection mechanism 3, thereby affecting the battery charging connection.

[0069] See also Figure 12 to Figure 13 A combined battery includes a battery body 5, a connecting member 51 is fixedly connected to the top of the battery body 5, a fourth limiting slot 52 is provided on the top of the connecting member 51, a fixing member 53 is fixedly connected to one side of the fourth limiting slot 52, a slider 54 is slidably connected to the inside of the fourth limiting slot 52, an adjusting slot 55 connected to the fourth limiting slot 52 is provided on the outside of the connecting member 51, and a moving member 56 fixedly connected to the slider 54 is slidably connected to the inside of the adjusting slot 55.

[0070] A second limiting groove 57 is provided on the side of the fourth limiting slide groove 52 away from the adjustment groove 55, and a plurality of equally spaced protrusions 58 are fixedly connected inside the second limiting groove 57. A third accommodating groove 59 is provided on the side of the slider 54 close to the second limiting groove 57. A limiting clamp 510 slidably connected to the second limiting groove 57 is slidably connected inside the third accommodating groove 59, and a sixth elastic member 511 is connected between the side of the limiting clamp 510 away from the second limiting groove 57 and the inner wall of the third accommodating groove 59.

[0071] A positive electrode sheet 512 and a negative electrode sheet 513 electrically connected to the battery body 5 are respectively disposed on the top of the slider 54 and the fixing member 53 .

[0072] The position of the fixing part 53 should be set according to the requirements of the handheld device to which the battery is adapted. For example, if the electrical connector of the handheld device is centered, then the fixing part 53 is set at the top center position of the connecting part 51. When the electrical connector of the handheld device is close to the side, then the fixing part 53 is set at the top side position of the connecting part 51. The purpose is to ensure that the battery electrodes correspond to the positions of the electrical connectors of the handheld device.

[0073] The first conductive connector 45 should be arranged on a side of the second mounting groove 42 away from the limiting assembly 35. The purpose is to facilitate the alignment connection between the electrode and the first conductive connector 45 when the battery is installed through unilateral positioning. Since the two electrodes on the battery are relatively arranged, the positions of the second conductive connector 47 and the first conductive connector 45 should remain relatively arranged, so that the second conductive connector 47 can be quickly connected to the battery electrode when it moves later, thereby improving efficiency. For example, when the first conductive connector 45 is connected to the positive electrode sheet 512 of the battery on the left side, the second conductive connector 47 will move from the right to the left and will quickly connect to the negative electrode sheet 513 of the battery.

[0074] In actual use, when the battery is installed, it is necessary to determine the insertion direction of the battery according to the position of the second conductive connector 47 of the first conductive connector 45. For example, the first conductive connector 45 is connected to the positive electrode and the second conductive connector 47 is connected to the negative electrode. Then, when the battery is inserted, it should be ensured that the fixing member 53 is close to the second conductive connector 47 and the slider 54 is close to the first conductive connector 45. By moving the moving member 56, the slider 54 is driven to move in the direction away from the fixing member 53 inside the fourth limiting slide groove 52, and moves to the side position inside the fourth limiting slide groove 52, so that the positive electrode sheet 512 on the top of the slider 54 can correspond to the position of the first conductive connector 45 designed to be close to the side inside the second installation groove 42. Then, the battery is inserted into the first installation groove 32, so that the first conductive connector 45 is connected to the positive electrode sheet 512 of the battery, and then the moved second conductive connector 47 will be connected to the negative electrode sheet 513 of the battery to form a passage, so that the battery can be charged. By installing batteries of different types in multiple first installation grooves 32 inside the installation shell 2, a battery module can be formed, so that one charger can charge batteries of multiple types.

[0075] When the slider 54 moves inside the fourth limiting groove 52, the limiting clamp 510 cooperates with the two adjacent protrusions 58 to restrict the slider 54 from stopping. Therefore, the position of the positive electrode sheet 512 can be adjusted by moving the slider 54, which can improve the adaptability of the battery to other devices.

[0076] The present invention provides the fourth limiting slot 52 and the slider 54. On the one hand, when the battery is installed, by moving the movable member 56, the slider 54 can be driven to move in the fourth limiting slot 52 in a direction away from the fixed member 53, and move to a position corresponding to the first conductive connector 45. Then the battery is inserted into the first installation slot 32, so that the first conductive connector 45 is connected to the positive electrode sheet 512 of the battery, and then the moved second conductive connector 47 is connected to the negative electrode sheet 513 of the battery to form a passage for charging. On the other hand, when the slider 54 moves in the fourth limiting slot 52, the limiting clamp 510 can cooperate with the two adjacent protrusions 58 to limit the slider 54 from stopping. Therefore, the position of the positive electrode sheet 512 can be adjusted by moving the slider 54, thereby improving the adaptability of the battery to other devices.

Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
