[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] To address the technical problem of auxiliary loading devices being incompatible with battery packs of different sizes, and the inability to adjust guidance and safety protection in sync with changes in battery pack size, resulting in poor compatibility, this invention provides a pack loading elevator. This elevator allows battery packs to be placed on a loading platform. The positioning component adjusts to fit the width of the battery pack, creating a snug fit and protection on both sides. The push-pull component, with its movable end moving along the loading direction, adjusts to the length of the battery pack, pushing it into the loading box. It is compatible with battery pack sizes within the adjustable range of the positioning and push-pull components, offering strong compatibility and providing safe and efficient loading operations.

[0020] It should be noted that the pack loading elevator described in this utility model is used for, but not limited to, battery packs. For ease of explanation, this utility model only uses the application of the pack loading elevator to battery packs as an example. The principle of the pack loading elevator applied to other types of equipment is essentially the same as that applied to battery packs, and will not be described in detail here.

[0021] Please see Figure 1 , Figure 1This is a three-dimensional structural diagram of a pack loading elevator according to an embodiment of the present invention. The pack loading elevator includes a loading platform 1, a lifting mechanism 3, and a conveying mechanism 2. The loading platform 1 is used to place the battery pack. The conveying mechanism 2 includes a positioning component 21 and a push-pull component 22. Both the positioning component 21 and the push-pull component 22 are mounted on the loading platform 1. The positioning component 21 has a positioning end with an adjustable spacing along the horizontal plane and perpendicular to the transport direction, used to adapt to the width of the pack and to limit and guide the pack along the loading direction. The push-pull component 22 has a movable end that can move along the loading direction, used to adapt to the length of the pack and to push the pack into the box. The positioning end of the positioning component 21 consists of two separate ends, and the distance between the two ends is adjusted. The spacing matches the width of the battery pack, and it fits against both sides of the battery pack, positioning the battery pack while guiding it to slide along the loading direction. The movable end of the push-pull assembly 22 abuts against the side of the battery pack away from the industrial and commercial storage cabinet. By moving along the direction of entry, it pushes the battery pack towards the industrial and commercial storage cabinet under the guidance of the positioning assembly 21. This greatly improves the efficiency of pack entry, increasing efficiency several times compared to manual handling. It can accommodate various packs of different sizes and specifications; by adjusting the positioning assembly 21 and the push-pull assembly 22, compatibility with different packs can be achieved. The protection of the pack is more comprehensive; during lifting and conveying, the positioning assembly 21 provides protection on both sides to avoid safety accidents.

[0022] In this embodiment, please refer to Figure 1 The pack loading elevator also includes a lifting mechanism 3, which has a lifting end that can be raised or lowered. The cargo platform 1 is connected to the lifting end of the lifting mechanism 3. The lifting mechanism 3 drives the cargo platform 1 to move up and down, raising and lowering the cargo platform to a specified height.

[0023] Understandably, the lifting mechanism 3 includes a motor 31, a coupling 32, a lead screw 33, a linear guide rail 34, and a drive frame 35. The motor 31 is connected to the lead screw 33 via the coupling 32, driving the lead screw 33 to rotate. The drive frame 35 is threadedly connected to the lead screw 33 and slidably connected to the linear guide rail 34. Driven by the motor 31, the rotation of the lead screw 33 causes the drive frame 35 to slide along the linear guide rail 34, thus lifting and lowering. Both the motor 31 and the linear guide rail 34 are mounted on the frame 4.

[0024] It should be noted that the lifting mechanism 3 can also directly use equipment with lifting functions such as forklifts. After being securely installed, it can meet the requirements for lifting operation.

[0025] In one embodiment, please refer to Figure 1 and Figure 2For positioning and safety protection, the positioning component 21 includes an adjustment mechanism 211, a fixed baffle 212, and a movable baffle 213. The fixed baffle 212 is fixedly connected to the cargo platform 1. The adjustment mechanism 211 is installed on the cargo platform 1 and has a movable end that extends and retracts relative to the fixed baffle 212. The movable baffle 213 is connected to the movable end of the adjustment mechanism 211 and is parallel to the fixed baffle 212. The adjustment mechanism 211 drives the movable baffle 213 to extend and retract, adjusting the distance between the fixed baffle 212 and the movable baffle 213, thereby achieving the function of matching battery packs of different widths.

[0026] Understandably, the adjustment mechanism 211 can be a screw-guide pair consisting of a handwheel, a lead screw, a guide rail, and a slider to drive the movable baffle 213 to move. Alternatively, it can be a mature device with linear drive function, such as an electric push rod or a hydraulic push rod.

[0027] Furthermore, to avoid obstruction of the battery pack during guidance, multiple rollers 201 are provided on opposite sides of both the fixed baffle 212 and the movable baffle 213. The battery pack slides relative to the rollers 201, resulting in a smoother guiding effect.

[0028] Furthermore, in order to facilitate the placement of the battery pack between the fixed baffle 212 and the movable baffle 213 from top to bottom and to reduce corner scratches, the top of the fixed baffle 212 and the movable baffle 213 are provided with inclined plates 202, and the two inclined plates 202 are inclined in opposite directions, thereby forming an opening larger than the width of the battery pack, which has the effect of guiding it to be placed in the middle, and reducing the probability of the plate edge directly scratching the battery pack.

[0029] In one embodiment, please refer to Figure 1 and Figure 2 In order to insert the battery pack into the box, the push-pull assembly 22 includes a linear drive mechanism 221 and a push plate 222. The linear drive mechanism 221 has a movable end that moves along the box insertion direction. The push plate 222 is connected to the movable end of the linear drive mechanism 221. The linear drive mechanism 221 is fixedly installed on the cargo platform 1. The push plate 222 is moved by the linear drive mechanism 221 to push the battery pack, thereby achieving the purpose of pushing the battery pack into the box.

[0030] Understandably, the linear drive mechanism 221 can be an existing device with linear drive function, such as a lead screw and guide pair driven by a stepper motor, a hydraulic push rod, or an electric push rod, which will not be elaborated on here.

[0031] Furthermore, to prevent the pack from being squeezed and deformed, the pusher plate 222 is provided with a buffer mechanism 223 on the side near the box entry direction to provide buffering when pushing the pack into the box.

[0032] Understandably, the buffer mechanism 223 includes a pad and a spring. The two ends of the spring are connected to the push plate 222 and the pad, respectively. The spring part is used to buffer the pack when it is put into the box. Due to errors in the mechanism and other aspects, the conveying distance will have a certain deviation. This buffer mechanism is used to provide cushioning and prevent the pack from being squeezed and deformed.

[0033] Furthermore, in order to provide a pull-out link function when the pack leaves the box, the push-pull assembly 22 also includes a zipper 224. The zipper 224 is connected to the movable end of the linear drive mechanism 221. The zipper 224 is provided with a hook 225 for hooking onto the pack. The chain part is used when a single pack is detected to be non-compliant with quality requirements and needs to be replaced after the pack has been put into the box.

[0034] Understandably, the zipper 224 is merely one feasible embodiment for ease of operation. Other connection structures, such as telescopic or rod-like components, can also be used as long as they serve the purpose of connection and pulling.

[0035] In one embodiment, please refer to Figure 1 and Figure 2 To facilitate the ejection of the battery pack, the cargo platform 1 includes a base 11 and rollers 12. At least two sets of rollers 12 are mounted on the base 11. The two sets of rollers 12 are symmetrically arranged on the base 11 and form a gap. The movable end of the push-pull assembly 22 is located on the central axis of the gap, that is, the rollers 12 and the battery pack roll relative to each other, so that the battery pack can be easily ejected. The gap allows the movable end of the push-pull assembly 22 to move, making the overall structure compact and capable of having a stroke range that can completely eject the battery pack.

[0036] In one embodiment, please refer to Figure 1 It also includes a frame 4, on which the lifting mechanism 3 is installed. The frame 4 is vertical and provides a support platform for the entire equipment. The cargo platform 1 is a horizontal part. The lifting mechanism 3 is installed inside the frame 4 to lift the horizontal cargo platform 1.

[0037] During installation and commissioning, firstly, the frame 4 and lifting mechanism 3 are installed on a flat ground according to the design requirements, ensuring the horizontality and verticality of the frame 4; then, the loading platform 1 is installed, ensuring the loading platform 1 is in good condition; finally, the positioning component 21 and push-pull component 22 on the conveying mechanism 2 are installed in sequence, and the electrical lines and pipes of each component are connected; after installation, the equipment is commissioned to ensure that the equipment can operate normally.

[0038] Understandably, a PLC controller can be used to control the entire equipment, employing existing mature control methods. Through programming, coordinated control of various mechanisms can be achieved. Based on preset programs and parameters, the controller is manually operated to complete the pack insertion operation. Specifically, the following steps are performed: Place the battery pack on the loading platform 1; operate the controller to raise the loading platform 1 to the specified height; operate the controller to drive the push-pull assembly 22 on the conveyor mechanism 2 to transport the pack into the box; push-pull assembly 22 returns to its original position; loading platform 1 returns to its original position; at this point, the pack insertion is complete; conveyor mechanism 2 will then continue to transport the next pack, and so on in a cycle.

[0039] To better understand this utility model, the following is combined with... Figures 1 to 2 The technical solution of this utility model is described in detail below: In use, the distance between the movable baffle 213 and the fixed baffle 212 is adjusted by the adjusting mechanism 211 to match the width of the battery pack to be placed in the box. The battery pack is placed on the loading platform 1, positioned between the fixed baffle 212 and the movable baffle 213, with the rollers 201 slidably connected to the battery pack, fitting against both sides of the battery pack to form a positioning and guide its sliding. When the battery pack is positioned on the loading platform 1, the push plate 222 is moved by the linear drive mechanism 221 to push the battery pack out of the loading platform 1 and into the storage cabinet, completing the boxing action. If, after the pack has been placed in the box, a single pack is found to be non-compliant with quality requirements and needs to be replaced, the hook 225 is attached to the battery pack to be removed, and the linear drive mechanism 221 moves in the opposite direction, driving the pull lock 224 and the hook 225 to pull the battery pack out of the storage cabinet. This allows for quick adjustment of the limit position to adapt to different needs. The pack is simple and efficient to place, with no complicated operating steps.

[0040] The specific embodiments of this utility model described above do not constitute a limitation on the scope of protection of this utility model. Any other corresponding changes and modifications made based on the technical concept of this utility model should be included within the scope of protection of the claims of this utility model.
