[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0034] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] like Figures 1 to 5 As shown, the battery pack heavy-duty lifting device of this embodiment includes a lifting mechanism 100, a support assembly 200, and a stop structure 300. The lifting mechanism 100 includes a drive member 110 and a cam mechanism 120, which is poweredly connected to the drive member 110, and the drive member 110 drives the cam mechanism 120 to rotate. The support assembly 200 is disposed above the lifting mechanism 100 and abuts against the cam mechanism 120. At least a portion of the stop structure 300 is located above the support assembly 200.

[0038] The heavy-duty battery pack lifting device provided in this embodiment can lift a battery pack carried by a tray. The support assembly 200 is used to place the tray and battery pack to be lifted. When the tray and battery pack move onto the support assembly 200, the stop structure 300 can block the tray and battery pack, thereby stopping their continued movement. The lifting mechanism 100 is located below the support assembly 200. When the tray and battery pack stop moving, the drive member 110 drives the cam mechanism 120 to rotate, pushing the support assembly 200 upward, thereby lifting the heavy-duty battery pack. After the battery pack completes subsequent processing and assembly, the drive member 110 drives the cam mechanism 120 to rotate again, causing the support assembly 200 to descend, thereby continuing to transport the battery pack onto the support assembly 200, realizing the cyclic lifting of the battery pack.

[0039] This heavy-duty lifting device for the battery pack, using a cam mechanism 120, is suitable for various working conditions and environments, adapting to heavy loads, high speeds, and high temperatures, and possesses high reliability and durability. It ensures smooth movement of the support assembly 200 during lifting, reduces vibration during movement, and enables precise motion control, meeting high-precision requirements during lifting and guaranteeing the safety and performance of the battery pack. Furthermore, the direct contact between the cam mechanism 120 and the support assembly 200 reduces energy loss during transmission, improves transmission efficiency, and features a simple structure and relatively low maintenance costs, thus helping to reduce equipment failure rates and repair expenses.

[0040] Furthermore, the lifting mechanism 100 also includes a transmission assembly 130, which is powered between the drive member 110 and the cam mechanism 120 to ensure stable and effective power transmission between the drive member 110 and the cam mechanism 120.

[0041] In this embodiment, the transmission assembly 130 includes a transmission shaft 131, a first sprocket 132, a second sprocket 133, and a transmission chain 134. The driving member 110 is configured as a drive motor. The first sprocket 132 is connected to the output end of the drive motor. The transmission shaft 131 passes through the second sprocket 133, and the transmission chain 134 is sleeved on the first sprocket 132 and the second sprocket 133, enabling chain transmission between the transmission shaft 131 and the driving member 110. Two cam mechanisms 120 are respectively connected to both ends of the transmission shaft 131, thereby achieving smooth movement of the support assembly 200. In some other embodiments, power transmission between the driving member 110 and the cam mechanism 120 can also be achieved through belt transmission, gear transmission, or other methods.

[0042] Chain drives have no elastic slippage or overall slippage, can maintain an accurate average transmission ratio, and have high transmission efficiency. The chain is made of metal material, and under the same operating conditions, the overall size of the chain drive is smaller, the structure is more compact, and it has a greater overload capacity, enabling it to work in high-temperature, humid, and dusty environments. In addition, compared with gear drives, chain drives have lower manufacturing and installation precision requirements and lower costs.

[0043] Optionally, the lifting mechanism 100 is provided with two transmission components 130, and each end of the transmission shaft 131 is connected to a cam mechanism 120, so that the lifting mechanism 100 can provide four-point support for the support component 200, ensuring the stability of the support component 200. The two transmission shafts 131 are arranged in parallel, and the drive component 110 is located between the two transmission shafts 131. This arrangement can save workshop layout space and reduce production costs.

[0044] Optionally, each cam mechanism 120 includes a connecting cam 121 and a roller 122. The connecting cam 121 is connected to the end face of the drive shaft 131, and the roller 122 is connected to the side of the connecting cam 121 facing away from the drive shaft 131. The center of the roller 122 is staggered with the rotation center of the drive shaft 131, so that the center of the roller 122 can rotate around the drive shaft 131. The support assembly 200 abuts against the roller 122. This arrangement can convert the sliding friction between the support assembly 200 and the cam mechanism 120 into rolling friction, thereby reducing energy loss during lifting, improving energy efficiency, saving operating costs, and reducing wear on the support assembly 200 and the cam mechanism 120, thus extending the service life of the heavy-duty lifting device for the battery pack.

[0045] Furthermore, the support assembly 200 includes a support frame 210, a protective plate 220, and abutment members 230. The support frame 210 is a frame structure used to connect and fix the support assembly 200, ensuring the structural strength of the support assembly 200. The protective plate 220 is connected above the support frame 210 to protect the lifting device and operators, ensuring operational safety. Multiple abutment members 230 are provided, and each abutment member 230 is connected below the support frame 210 and abuts against the cam mechanism 120.

[0046] Optionally, the support assembly 200 further includes positioning elements 240, which are disposed above the protective plate 220. These positioning elements 240 are used to position the tray and battery pack on the support assembly 200, preventing the battery pack from shifting position during lifting and improving the positioning accuracy of the battery pack during the lifting process. In this embodiment, two positioning elements 240 are disposed diagonally on the protective plate 220. The positioning elements 240 are configured as positioning pins, resulting in a simple structure and easy installation.

[0047] In this embodiment, the protective plate 220 is provided with a first through hole 221, and the stop structure 300 can be inserted through the first through hole 221. The bottom of the stop structure 300 is fixed and the top is located above the protective plate 220, and it is used to stop the tray and the battery pack.

[0048] Furthermore, the heavy-duty lifting device for the battery pack also includes a backstop structure 500, at least part of which is located above the support assembly 200. The backstop structure 500 and the stop structure 300 are spaced apart, and the tray and the battery pack can be confined between the stop structure 300 and the backstop structure 500 to prevent backflow of the tray and the battery pack, thereby further ensuring the stability of the battery pack.

[0049] Specifically, the anti-reverse structure 500 includes a rotation stop 510 and a second mounting base 520. The rotation stop 510 is rotatably mounted on the second mounting base 520. The protective plate 220 is provided with a second through hole 222, and part of the rotation stop 510 can pass through the second through hole 222. The rotation stop 510 has an inclined surface 511 on the side opposite to the stop structure 300, and the inclined surface 511 is located above the protective plate 220.

[0050] As the tray moves toward the stop structure 300, it presses against the inclined surface 511. The rotating stop 510 rotates under the push of the tray, gradually rotating until it is completely placed under the tray. When the tray and battery pack continue to move and come into contact with the stop structure 300, the tray no longer presses against the rotating stop 510. At this time, the rotating stop 510 rotates back to its original position, blocking the end of the tray away from the stop structure 300 and preventing the tray and battery pack from flowing back.

[0051] Optionally, the anti-reverse structure 500 also includes a first sensor 530, which is connected to the second mounting base 520 and can detect the position of the rotating stop 510, identify whether the tray is pressing against the rotating stop 510, and thus determine whether the lifting device is operating normally.

[0052] Furthermore, the heavy-duty lifting device for the battery pack also includes a guide mechanism 400, which includes a moving component 410 and a guide component 420. The guide component 420 extends in the vertical direction. The moving component 410 is connected to the support component 200 and is movably connected to the guide component 420, further ensuring the stability of the support component 200 during movement.

[0053] Specifically, the guide assembly 420 includes a first mounting base 421 and a guide shaft 422. The guide shaft 422 extends in a vertical direction, and the first mounting base 421 supports the guide shaft 422. The movable assembly 410 is movably connected to the guide shaft 422. In this embodiment, the first mounting base 421 includes an L-shaped plate 4211 and a reinforcing rib 4212. The guide shaft 422 is mounted on one end of the L-shaped plate, and the reinforcing rib 4212 is connected within the bending structure of the L-shaped plate to ensure the structural strength of the first mounting base 421.

[0054] Specifically, the moving component 410 includes a fixing member 411 and several rolling members 412. The fixing member 411 is connected to the support component 200, and the rolling members 412 are connected to the fixing member 411. The rolling members 412 abut against the guide component 420, thereby reducing friction and wear between the moving component 410 and the guide component 420. In this embodiment, two rolling members 412 are provided, and the two rolling members 412 are set at an angle to ensure stable movement. For example, the rolling members 412 can be configured as rolling bearings, rollers, etc.

[0055] Optionally, the guide component 420 can also be configured as a slide rail, slide groove or other structure, and the moving component 410 can be configured as a slider or other common guide structure, which will not be described in detail here.

[0056] Optionally, the battery pack heavy-duty lifting device is provided with multiple guide mechanisms 400, which are spaced apart from each other. In this embodiment, two guide mechanisms 400 are provided, and the two guide mechanisms 400 are respectively provided at both ends of the support component 200 to ensure the stability of the directional movement of the support component 200.

[0057] Furthermore, the heavy-duty lifting device for the battery pack also includes a base 600, which is used to support the heavy-duty lifting device for the battery pack. Specifically, the lifting mechanism 100, the stop structure 300, the guide mechanism 400 and the anti-reverse structure 500 are all fixed on the base 600 to ensure the stability of the heavy-duty lifting device for the battery pack.

[0058] Optionally, a second sensor is provided on the base 600 to detect whether the support component 200 has been raised or lowered into position. In this embodiment, two second sensors are provided, arranged side by side in the vertical direction, to detect whether the support component 200 has been raised or lowered into position, respectively.

[0059] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
