[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] This invention utilizes a clamping plate, a baffle, and a first rotating rod. A worker drives a motor to open the door, which in turn drives a transmission mechanism to rotate the first rotating rod. The first rotating rod causes the door to open intermittently, simultaneously moving the clamping plate. The transmission mechanism then moves a movable plate. A first movable rod on the movable plate is pressed down by a first protrusion, causing the clamping plate to descend and clamp the battery. The clamping plate then pulls the battery out of the socket. The user replaces the battery and slides the old battery onto a positioning frame until it reaches the baffle. After a period of time, the door closes via the transmission mechanism. Simultaneously, the movable frame moves the clamping plate, which, through a second protrusion, presses against a second movable rod. This movement causes the second movable rod to move a third connecting rod. One end of the third connecting rod moves a slider, which in turn rotates the baffle, disengaging it from the battery. At this point, the clamping plate and the battery are clamped together, allowing the battery pack to connect to the socket for charging.

[0015] It is easy to use and simple to operate. The battery pack can be automatically pulled out when it is removed and can be automatically positioned and connected during installation. It effectively solves the problem of reduced lifespan of battery pack and socket caused by workers violently plugging and unplugging. In addition, the door can automatically close after a period of time after being opened, which can effectively prevent the door from being not closed tightly and causing humid air to enter, thus reducing the lifespan of the internal battery.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Please see Figure 1-6 The present invention provides a technical solution:

[0027] A battery pack charging and swapping box includes a box body 1. A charging compartment 2 is fixedly connected inside the box body 1. Cavities are provided on both ends of the charging compartment 2. A first rotating rod 8 is rotatably connected inside the cavity. A door 9 and a fixing rod 7 are fixedly connected to the circumferential surface of the first rotating rod 8. A first protrusion 3 is fixedly connected to the upper inner surface of the cavity. A movable plate 11 is slidably connected to the inner side wall of the cavity. Multiple first moving rods 12 are slidably connected inside the movable plate 11. A clamping plate 14 is fixedly connected to the other end of the first moving rod 12. A second protrusion 18 is fixedly connected to the side surface of the movable plate 11. The charging compartment 2... A positioning frame 22 is fixedly connected to the part, and a baffle 15 is rotatably connected inside the positioning frame 22. A second moving rod 19 is slidably connected to the side surface of the positioning frame 22, and one end of the second moving rod 19 is in contact with the inclined surface of the second protrusion 18. A limit groove 16 is provided inside the baffle 15, and a slider 17 is slidably connected inside the limit groove 16. A third connecting rod 21 is rotatably connected to the lower surface of the slider 17, and the other end of the third connecting rod 21 is rotatably connected to one end of the second sliding rod. A transmission mechanism is provided inside the cavity, and the door body 9, the moving plate 11 and the baffle 15 are driven synchronously through the transmission mechanism.

[0028] When using this device, the motor 27 is turned on, which drives the turntable 28 to rotate. The turntable 28 drives the fourth connecting rod 29 to rotate, which in turn drives the rack 30 to move. The rack 30 and the fourth gear 31 mesh with each other, and the fourth gear 31 drives the incomplete gear 32 to mesh with each other. At this time, the incomplete gear 32 and the third gear 25 mesh with each other, and the third gear 25 drives the second rotating rod 24 to rotate. The second rotating rod 24 drives the drive wheel to rotate. When the incomplete gear 32 and the third gear 25 disengage, the fixed rod 7 on the drive wheel enters the driven groove inside the driven wheel 33, causing the driven wheel 33 to rotate intermittently. The driven wheel 33 drives the third gear 25 to rotate, and the third gear 25 moves the second connecting rod 10. The second connecting rod 10 drives the third gear 25 to rotate. The fixed rod 7 rotates, which drives the first rotating rod 8 to rotate. The first rotating rod 8 drives the door 9 to open. The second gear 5 meshes with the first gear 4. The first gear 4 drives the second connecting rod 10 to move. The second connecting rod 10 drives the moving plate 11 to move. The moving plate 11 drives the first moving rod 12 to move. When the first moving rod 12 and the first protrusion 3 are in contact and the first moving rod 12 is squeezed, the first moving rod 12 drives the clamping plate 14 to descend. The clamping plate 14 clamps the upper and lower surfaces of the battery pack, so that the battery pack moves outward with the clamping plate 14. When the first moving rod 12 moves to the outermost side of the first protrusion 3, the first moving rod 12 moves upward, and the clamping plate 14 and the two sides of the battery pack are released, making it convenient for the user to take out the battery pack.

[0029] After the user replaces the battery, the battery pack to be charged is placed inside the charging compartment 2 through the positioning frame 22 and blocked by the baffle 15. At this time, the motor 27 drives the turntable 28 to reset the fourth link 29, and the fourth link 29 drives the rack 30 to reset, so that the door 9 closes slowly and drives the moving plate 11 to move. The moving plate 11 drives the second protrusion 18 to move. The second protrusion 18 lowers the second moving rod 19 and squeezes the second spring 20. The second moving rod 19 drives the third link 21. The third link 21 pushes the slider 17 to slide in the limiting groove 16. The third link 21 drives the baffle 15 to rotate, so that the baffle 15 is released from the block. At this time, the clamps 14 at the upper and lower ends fit and fix the battery pack. As the moving plate 11 drives the clamps 14 to move, the connection port of the battery pack is connected.

[0030] It is easy to use and simple to operate. The battery pack can be automatically pulled out when it is removed and can be automatically positioned and connected during installation. This effectively solves the problem of reduced lifespan of battery pack and socket caused by workers violently plugging and unplugging. In addition, the door 9 can automatically close after a period of time after being opened, which can effectively prevent the entry of humid air due to the door 9 not being closed tightly, thus preventing the internal battery lifespan from decreasing. It also fixes the battery pack during charging, effectively preventing the battery pack interface from detaching due to external impact.

[0031] The transmission mechanism includes a first gear 4 rotatably connected to the upper surface of the cavity and a second gear 5 rotatably connected to the lower surface of the cavity, with the second gear 5 and the first gear 4 meshing with each other. A second connecting rod 10 is rotatably connected to the surface of the first gear 4, and one end of the second connecting rod 10 is fixedly connected to one end of the moving plate 11. A first connecting rod 6 is rotatably connected to the surface of the second gear 5, and the other end of the first connecting rod 6 is rotatably connected to the fixed rod 7, which facilitates opening the door 9 while driving the clamping plate 14 to move and remove the battery pack.

[0032] The cavity has a second rotating rod 24 rotatably connected to its inner lower surface. The second rotating rod 24 has a third gear 25 and a drive disk 26 fixedly connected to its circumferential surface. One end of the third gear 25 is fixedly connected to a driven wheel 33, and the driven wheel 33 has a driven groove on its circumferential surface. The drive disk 26 has a fixed rod 7 fixedly connected to its upper surface, and the size of the fixed rod 7 matches the size of the driven groove, which facilitates self-locking of the first gear 4 and the second gear 5 and can also drive the first gear 4 and the second gear 5 to perform intermittent motion.

[0033] The cavity has a motor 27 fixedly connected to its inner lower surface, a turntable 28 fixedly connected to the output end of the motor 27, a fourth connecting rod 29 rotatably connected to the surface of the turntable 28, a rack 30 slidably connected to the inner lower surface of the cavity, and the other end of the rack 30 rotatably connected to one end of the fourth connecting rod 29. A fourth gear 31 rotatably connects to the inner lower surface of the cavity, and an incomplete gear 32 is fixedly connected to one end of the second gear 5. The incomplete gear 32 and the third gear 25 mesh with each other, and the rack 30 and the fourth gear 31 mesh with each other, which facilitates the reciprocating motion of the rack 30 and the reciprocating motion of the fourth gear 31. This allows the incomplete gear 32 and the third gear 25 to mesh, enabling intermittent stops to facilitate the placement of the battery pack by the staff.

[0034] A first spring 13 is fixedly connected between the first moving rod 12 and the moving plate 11 to facilitate the reset of the first moving rod 12 when it is pressed by the first protrusion 3. A second spring 20 is fixedly connected between the second moving rod 19 and the side surface of the positioning frame 22 to facilitate the reset of the second moving rod 19 when it is pressed by the second protrusion 18.

[0035] The clamping plate 14 is made of elastic material. The height of the clamping plate 14 is less than the height of the positioning frame 22, and the length of the clamping plate 14 is the same as the width between the two positioning frames 22. This facilitates the protection of both sides of the battery pack when it is fixed and clamped, and prevents the clamping plate 14 from blocking the battery pack when it is removed.

[0036] The rotating shafts of the two first gears 4 are fixedly connected to pulleys 23, and the two pulleys 23 are connected by belt drive, which facilitates the synchronous rotation of the two first gears 4 and drives the second connecting rod 10 to move.
