[0002] Shared electric motorcycles have brought great convenience to users and have achieved rapid development since they were put on the market. The battery of an electric motorcycle will heat up when it is charged, and it will age after long-term use, which can easily become a safety hazard. In addition, due to the shared nature of shared electric motorcycles, users do not take care of them as they would their personal belongings, which makes it easier to damage the motorcycle itself and the battery, thus shortening its service life.

[0003] Although existing shared electric vehicle charging cabinets are equipped with fire-fighting equipment, current battery fires are characterized by fast speed and high temperature, so firefighting is difficult. At the same time, once these fire-fighting equipment fail due to an accident, the fire will become uncontrollable, causing the fire in one battery pack to spread to other battery packs, creating the risk of expanding the fire. Summary of the invention

[0004] The present invention provides a battery pack installation structure for a charging cabinet and a charging cabinet, which can isolate a burning battery pack when a fire fighting system fails to put out the fire in time, so that the burning battery pack will not ignite adjacent battery packs.

[0012] Preferably, an extension plate is vertically fixed to the side wall of the driving plate, the transfer block is a triangular prism, and two adjacent sides of the transfer block are provided with adapter plates, one of the adapter plates is rotatably connected to the extension plate, and the other adapter plate is rotatably connected to the connecting rod.

[0013] Preferably, the battery pack installation structure for the charging cabinet also includes a conveying mechanism arranged on the top surface of the fixed frame and the movable frame for conveying the battery pack.

[0014] Preferably, the transmission mechanism includes a motor, a driving gear arranged on an output shaft of the motor, and a plurality of driven gears arranged in rows and spaced apart and driven to rotate by the driving gear.

DETAILED DESCRIPTION

[0033] A preferred embodiment of the present invention is described in detail below with reference to the accompanying drawings.

[0034] To achieve the above purpose, the embodiment of the present invention adopts the following technical solution: Figure 1 , a battery pack installation structure for a charging cabinet, comprising a fixed frame 10, a movable frame 20 and a driving mechanism, wherein the movable frame is arranged on the open side of the fixed frame 10, and the driving mechanism is arranged between the fixed frame and the movable frame, and is used to drive the movable frame to rotate relative to the fixed frame. It should be noted that the movable frame is rotatably arranged with the fixed frame, so that when the movable frame is connected to the fixed frame 10, an integral main frame structure can be formed, and the main frame structure can be used to accommodate a battery pack 90 to achieve the installation of the battery pack; in addition, when the movable frame rotates relative to the fixed frame, a track for the battery pack to detach from the main frame can be formed, so that when the fire cannot be suppressed, the driving mechanism can drive the movable frame to rotate and tilt relative to the fixed frame to form a track for the battery pack to slide, so that the battery pack can slide along the track and fall to a safe position, so as to achieve isolation from the burning battery pack and prevent the spread of fire.

[0035] Reference Figure 2 As a preferred technical solution of this embodiment, the fixed frame 10 includes a fixed frame 110, a fixed plate 120 and a top plate 130. The fixed frame 110 is a rectangular box structure, and the long side of the fixed frame is a through open structure. There are two groups of fixed plates, and the two groups of fixed plates are symmetrically arranged at the two long side positions of the fixed frame. The top plate 130 is fixed on the top of the fixed plate. In this way, the fixed frame, the fixed plate and the top plate form the main structure of the fixed frame.

[0036] It should be noted that each group includes multiple fixing plates, and the multiple fixing plates are vertically fixed along the long sides of the fixing frame 110 .

[0037] Further, see Figure 2 The movable frame 20 includes a movable frame 210 and a movable plate 220. The movable frame 20 is also a rectangular box structure, and the long side of the movable frame is a through open structure. There are two movable plates 220, and the two movable plates are symmetrically arranged vertically at the two long side positions of the movable frame. In this way, the main structure of the movable frame is formed by the movable frame and the movable plate. It should be pointed out that in order to realize the rotation of the movable frame relative to the fixed frame, the bottom of the movable frame in this embodiment can be connected to the bottom of the fixed frame by a hinge to realize the rotation and docking of the main structure of the movable frame and the main structure of the fixed frame.

[0038] Reference Figure 3 , Figure 4 In some embodiments, the driving mechanism includes a driving source 310, a driving plate 320, a transmission block 330 and a connecting rod 340. The driving source 310 is fixedly arranged inside the fixed frame 10. The driving source in this embodiment can be a hydraulic cylinder. The driving plate 320 is fixedly arranged at the output end of the driving source. The transmission block 330 is rotatably arranged at the end of the driving plate away from the driving source. The connecting rod 340 is rotatably arranged at the end of the transmission block away from the driving plate. At the same time, the end of the connecting rod away from the transmission block is rotatably connected to the side wall of the movable frame 20. When the battery pack is installed, the movable frame is parallel to the fixed frame, and the movable frame and the fixed frame work together to form a space for accommodating the battery pack. When a fire occurs and cannot be controlled, the driving plate can be driven to move horizontally by the driving source. When the driving plate moves horizontally, it drives the transmission block to rotate. When the transmission block rotates, it drives the movable frame to rotate downward through the connecting rod, thereby forming a track inclined from the fixed frame to the movable frame, so that the battery pack can slide from the space formed by the fixed frame and the movable frame to a safe position, thereby isolating the battery pack.

[0039] Further, see Figure 4, the side wall of the driving plate 320 is vertically fixed with an extension plate 321, the transmission block 330 is a triangular prism, and the two adjacent sides of the transmission block 330 are provided with adapter plates 331, one of which is rotatably connected to the extension plate, and the other is rotatably connected to the connecting rod 340. When in use, the bottom surface of the triangular prism-shaped transmission block is horizontally placed on the bottom wall of the fixed frame, so that when the transmission block rotates under the action of the driving source, one side edge of the transmission block can rotate. When the transmission block rotates, the connecting rod can drive the movable frame to rotate relative to the fixed frame. It should be noted that the reason why the transmission block is set in the form of a triangular prism is that the driving source in this embodiment is located inside the fixed frame. When the driving source is in action, the horizontal movement must be converted into a small-range circular motion for driving the movable frame to rotate. It is precisely because of the existence of the transmission block that the movable frame can be driven from the inside.

[0040] Reference Figure 5 , Figure 6 Furthermore, in order to facilitate the battery pack to slide out from the fixed frame and the movable frame, the battery pack installation structure for the charging cabinet also includes a conveying mechanism, which is arranged on the top surface of the fixed frame 10 and the movable frame 20, and is used to convey the battery pack. It should be noted that the conveying surface of the conveying mechanism is located above the top surface of the fixed frame and the movable frame, so that the bottom surface of the battery pack is in contact with the aforementioned conveying surface, so that the battery pack can be conveyed.

[0041] Further, see Figure 6 The transmission mechanism includes a motor 410, a driving gear 420 and a driven gear 430. The motor is a dual-output shaft motor. The driving gear 420 is arranged on the output shaft of the motor. There are multiple driven gears 430, and the multiple driven gears 430 are arranged in rows and spaced apart. The driven gears are driven by the driving gears to rotate to achieve the purpose of transmitting the battery pack.

[0042] The following describes the working process of the transmission mechanism by means of the installation of the transmission mechanism and the fixed frame. The dual-output shaft motor is located in the middle of the inner bottom wall of the fixed frame, and the shafts at both ends of the dual-output shaft extend outward to the two side positions of the fixed frame. The driving gear is located on the output shaft, and multiple driven gears are arranged to rotate along the long side wall of the fixed frame. At the same time, in order to facilitate the driving of the driven gear by the driving gear, a driving sprocket 440 is provided on the shaft of the driving gear, and a driven sprocket 450 is provided on the shaft of the driven gear, and a chain 460 is connected between the driving sprocket and the driven sprocket, so that multiple driven sprockets can rotate synchronously under the action of the chain. When in use, when the driving gear rotates under the drive of the motor output shaft, it can synchronously drive the driving sprocket to rotate, and the driving sprocket then drives multiple driven sprockets to rotate through the chain, and the driven sprocket then drives the driven rack to rotate, thereby realizing the rotation of the driven gears on both sides, and thus achieving the effect of transmitting the battery pack.

[0043] Reference Figure 7 , Figure 8 In some embodiments, the battery pack mounting structure for the charging cabinet further includes a back plate 510, a connector 520 and a flip mechanism. The back plate 510 is rotatably arranged at an open side of the fixed frame 10. The connector 520 is arranged on the back plate for charging the battery pack. The flip mechanism is arranged on the top of the fixed frame for driving the back plate to rotate relative to the fixed frame. Further, the flip mechanism includes a flip cylinder 531, a flip plate 532, a flip rod 533 and a flip disk 534. The flip cylinder is fixedly arranged on the top of the top plate, the flip plate is fixedly arranged on the output end of the flip cylinder, the flip rod is rotatably arranged on the flip plate, and the flip disk is rotatably arranged on the top of the top plate. The flip plate is rotatably connected to the back plate by the rotating shaft, and the flip plate is rotatably connected to the back plate by the rotating shaft. When in use, the flip plate can be translated along the top surface of the top plate under the drive of the flip cylinder. Since the flip rod is rotatably connected to the flip plate, the flip rod can be driven to swing when the flip plate is translated. The flip rod drives the flip plate when it swings, thereby driving the flip plate to rotate. When the flip plate rotates, it drives the back plate to rotate, so as to realize the rotation of the back plate relative to the fixed frame, thereby realizing automatic plugging and unplugging of the joint, so that when the battery pack needs to be isolated, it can automatically detach from the battery pack, so that the surface of the battery pack is not connected, and interference can be avoided when the battery pack slides.

[0044] In other embodiments, referring to Figure 8The battery pack installation structure for the charging cabinet also includes a fire sprinkler 610 and a telescopic mechanism. The fire sprinkler 610 is arranged on the top of the fixed frame 10, and the telescopic mechanism is also arranged on the top of the fixed frame. The telescopic mechanism is used to drive the fire sprinkler to move relative to the fixed frame. In this embodiment, a through hole is opened on the top plate, and a guide cylinder 621 is fixedly arranged on the side of the through hole of the outer wall of the top plate. At the same time, the outer wall of the top plate on both sides of the guide cylinder is rotatably connected with a transfer rod 622. The fire sprinkler is slidably arranged in the through hole, and a mounting plate 611 is arranged on the top of the fire sprinkler. Furthermore, the telescopic mechanism includes a telescopic cylinder 623, a telescopic plate 624 and a driving rod 625. When in use, the telescopic cylinder is fixedly arranged on the top of the top plate, the telescopic plate is fixedly arranged on the output end of the telescopic cylinder, and one end of the driving rod is connected to the telescopic cylinder. The side walls of the plate are rotatably connected, and the other end of the driving rod is rotatably connected to the mounting plate 611 at the top of the fire-fighting joint. At the same time, the end of the connecting rod away from the top plate is rotatably connected to the middle part of the driving rod. When working, the telescopic plate can be driven to translate on the top of the top plate under the drive of the telescopic cylinder, and the telescopic plate then drives the driving rod to rotate. Since the driving rod can rotate along the connecting rod, and under the limiting action of the guide cylinder, the fire sprinkler can be vertically telescopically moved along the guide cylinder. In this way, the distance of the fire sprinkler relative to the fixed frame can be adjusted to realize the lifting function of the fire sprinkler. Since the fire sprinkler can be lifted and lowered, after the battery pack is inserted into the fixed frame, the fire sprinkler will be inserted downward into the battery pack, so that a single package fire can be sprayed. At the same time, the sprinkler can be automatically lifted and lowered, and interference can be avoided when the battery pack slides out of the fixed frame.

[0045] Reference Fig. 9 , Fig.10 , the present embodiment further provides a charging cabinet, wherein the battery pack mounting structure for the charging cabinet as described above is arranged in rows inside the charging cabinet. It should be noted that the charging cabinet is provided with a battery compartment, a fire fighting compartment and an isolation compartment 80 from top to bottom in sequence, and a plurality of plywood distributed horizontally and vertically is arranged inside the battery compartment, and the plurality of plywood forms a drawer for placing the aforementioned battery pack mounting structure in the battery compartment, and a fire fighting bottle is arranged inside the fire fighting compartment. The isolation compartment is arranged at the bottom of the charging cabinet, and the isolation compartment is buried underground to ensure that the isolation compartment is fully isolated, and a slide 70 is arranged on the inner back of the charging cabinet, and the slide can provide space for the battery pack to slide down. When in use, when there is a fire in a battery pack that cannot be extinguished, the aforementioned battery pack mounting structure can be used to transfer other battery packs to the slide, and then transport them to the isolation compartment at the bottom through the slide to avoid other battery packs from being damaged.

[0046] In addition, a mezzanine is provided on the plywood, which is used for the arrangement of fire-fighting pipes and lines.
