Description

Technical Field

[0001] This invention belongs to the field of battery pack lifting equipment technology, specifically a lifting equipment for synchronous loading of double-row modules into a box for new energy vehicle battery packs. Background Technology

[0002] The battery pack of a new energy vehicle is the core energy storage unit of an electric vehicle. It is a precise integration of cells, modules, a battery management system (BMS), a thermal management system, and a high-voltage electrical structure. It undertakes the core functions of energy storage, output, and safety protection. The battery pack is a power unit that integrates multiple battery modules and is equipped with auxiliary systems such as BMS, thermal management, and high-voltage wiring harnesses. Its weight is usually over 200 kg. It is located at the bottom of the vehicle to lower the center of gravity and improve collision safety. Therefore, it requires a graded recycling device for targeted processing. Lifting equipment is a special device used in lifting machinery for lifting, handling, and loading / unloading heavy objects. It is a core component of lifting equipment. Its main function is to grasp, fix, and move various materials through mechanical or suction forces. The dual-row module synchronous loading lifting equipment for new energy vehicle battery packs is a special device designed to improve the efficiency and accuracy of battery pack assembly. Its core function is to achieve precise synchronous positioning, clamping, and loading of two rows of battery modules in a limited space, solving the problems of large space occupation and low positioning accuracy of traditional lifting equipment.

[0003] Existing synchronous loading devices for dual-row battery packs in new energy vehicles have certain drawbacks. These devices typically use mechanical clamping blocks to hold the battery modules directly into the box. However, due to the diverse sizes of battery modules, insufficient space between the clamping blocks when simultaneously holding two modules can prevent them from gripping the optimal clamping points. Instead, they may only clamp the sides of the battery modules, leading to uneven force distribution and potential loss of battery modules during transport. This damage results in economic losses and reduces the effectiveness of the synchronous loading device, failing to meet user needs. Summary of the Invention

The control valve, transmission bevel gear structure, transmission gear, rotating gear and rotating motor can achieve precise on / off control of vacuum suction cup, avoid the local failure of a single vacuum suction cup from spreading to the whole adsorption system, thereby effectively protecting the adsorption structure and extending the service life of the adsorption structure.

[0024] (3) By using the protective components, the protective tube, the sealing structure and the sealing seat together, when the vacuum suction cup leaks air, the sealing structure can move upward and fit with the sealing seat to seal, thus closing the vacuum suction cup and no longer affecting the overall vacuum system of the adsorption structure. The normal units of other vacuum suction cups can continue to maintain normal vacuum, ensuring the overall adsorption force is stable, avoiding the problem of reduced adsorption force of the adsorption structure on the battery mold during the transfer process, and preventing the battery mold from falling off. The support spring and guide rod together can make the sealing plate and sealing block stably suspended in the middle of the inner side of the protective tube and make the sealing structure move stably. The sealing plate and sealing ring together can improve the sealing effect of the sealing seat, thereby ensuring that the pipeline of the leaking vacuum suction cup is completely closed, ensuring the adsorption stability of other vacuum suction cups, and improving the use effect of the adsorption structure.

When the lifting screw transmission device 29 and the lifting pipe 30 control the lifting of the support frame 25, they prevent the support frame 25 from shaking, thereby ensuring the stability of the car battery pack when it is placed in the box. The bottom end of the lifting pipe 30 is connected to the upper end face of the support frame 25. In this invention, the movable support base 23 is provided with a weight-reducing groove, and a reinforcing rod 31 connected to the lifting screw transmission device 29 is provided on the inner bottom surface of the movable support base 23. The reinforcing rod 31 is provided with a mechanism for driving the lifting screw. The transmission device 29 operates with lifting bevel gear structures 32. Several lifting bevel gear structures 32 are connected by a second transmission rod 33. The two ends of the second transmission rod 33 are rotatably connected to the inner side of the movable support base 23. The outer wall of the movable support base 23 is equipped with a lifting drive motor 34 that controls the rotation of the second transmission rod 33. When the lifting drive motor 34 is started, it drives several lifting bevel gear structures 32 to rotate synchronously through the second transmission rod 33. This causes the lifting bevel gear structures 32 to drive the lifting screw transmission device 29 to work. The lifting screw transmission device 29 drives the support frame 25 to rise and fall through the lifting tube 30.

[0054] In this embodiment, the lifting drive motor 34 is started, which drives the second transmission rod 33 to rotate, so that the second transmission rod 33 drives the lifting bevel gear structure 32 to rotate synchronously. The lifting bevel gear structure 32 drives the lifting tube 30 to move, so that the lifting tube 30 drives the support frame 25 to rise and fall. The support frame 25 drives the first hoisting seat 1 to move, so that the first hoisting seat 1 drives the second hoisting seat 2 to move, so that the second hoisting seat 2 drives the fixed car battery pack to move up and down.

[0055] Example 2

[0056] Based on Example 1, referring to Figure 5 - Figure 9 This is the second embodiment of the present invention. In this embodiment, the hoisting mechanism further includes a protective component for protecting the vacuum suction cup 16. The protective component includes a filter screen 51 disposed on the lower inner side of the vacuum suction cup 16 and a weight sensor 52 disposed on the filter screen 51. An alarm connected to the weight sensor 52 is disposed on the first hoisting base 1. When the value of the weight sensor 52 reaches a set value, the alarm sounds and activates the control valve 35, causing the control valve 35 to close. The protective component includes a control valve 35 disposed on the second air guide pipe 21 near the vacuum suction cup 16. The control valve 35 is connected to the vacuum suction cup 16 and controls the opening and closing of the vacuum suction cup 16. When the weight sensor 52 detects that the weight of the filter screen 51 has increased to a certain value, the control valve 35 closes the vacuum suction cup 16.

[0057] The protective assembly also includes a transmission bevel gear structure 36 coaxially connected to the valve stem of the control valve 35 and a transmission gear 37 coaxially connected to the transmission bevel gear structure 36. The interior of the second hoisting base 2 is provided with rotating gears 38 that mesh with several transmission gears 37 respectively. The rotating gears 38 are located at the center of the inner side of several second air guide pipes 21. A rotary motor 39 is provided on the rotating gear 38. When the rotary motor 39 is started, it drives the rotating gear 38 to rotate, so that the rotating gear 38 drives several transmission gears 37 to rotate. The transmission gears 37 drive the valve stem of the control valve 35 to rotate through the transmission bevel gear structure 36, thereby controlling the opening and closing of the control valve 35.

[0058] In this embodiment, the adsorption device 17 is started, causing the vacuum suction cup 16 to perform extraction, the filter screen 51 to filter the gas entering the vacuum suction cup 16, and the weight sensor 52 to weigh the filter screen 51. When the weight value of the weight sensor 52 reaches the set value, the alarm connected to the weight sensor 52 sounds an alarm and starts the control valve 35 to close the second air guide pipe 21, shut down the adsorption device 17, and clean the filter screen 51.

[0059] Example 3

[0060] Based on Example 2, referring to Figure 7 - Figure 11 This is the third embodiment of the present invention. In this embodiment, the protective component further includes a protective tube 40 disposed on the second air guide tube 21. The protective tube 40 is disposed above the control valve 35 and is connected to the second air guide tube 21. A sealing structure 41 is movably disposed in the middle of the inner side of the protective tube 40. A sealing seat 42 that cooperates with the sealing structure 41 is disposed on the top inner side of the protective tube 40. When a vacuum suction cup 16 leaks air, the vacuum degree of that unit drops rapidly, causing the sealing structure 41 to move upward and fit and seal with the sealing seat 42, thereby closing the vacuum suction cup 16. This effectively protects the adsorption structure 4, reduces the drop in vacuum degree of the adsorption structure 4, and no longer affects the overall vacuum system. Other normal units can continue to maintain normal vacuum degree, ensuring the overall adsorption force is stable.

[0061] In this embodiment, several vacuum suction cups 16 adsorb onto the top surface of the battery module. When a vacuum suction cup 16 is not completely connected to the top surface of the car battery pack, the vacuum degree of the unit drops rapidly due to air leakage, and the pressure difference inside the protective tube 40 becomes unbalanced. The vacuum degree on the suction cup side decreases, and the negative pressure weakens, while the protective tube 40 still maintains a high negative pressure. Due to the normal operation of other units or the continuous suction of the adsorption device 17, the negative pressure above the sealing structure 41 is greater than the negative pressure below, forming an upward driving force. Under the action of the upward negative pressure difference suction, the sealing structure 41 overcomes its own gravity and the equilibrium state when suspended, and is adsorbed and moves upward, accurately adhering to and pressing the upper sealing seat 42, which can completely block the air passage of the unit and prevent the negative pressure of the adsorption device 17 from continuously leaking out through the leakage point.

[0062] In this invention, a support block 43 is provided at the bottom inner side of the protective tube 40. The support block 43 has several first ventilation slots that communicate with the second air guide tube 21. The sealing structure 41 has several second ventilation slots that are aligned with the first ventilation slots. The first ventilation slots and the second ventilation slots work together to allow gas to flow. The upper end of the support block 43 is provided with a circular array of support springs 44 that provide elastic support for the sealing structure 41. The support springs 44 allow the sealing structure 41 to flexibly suspend in the middle of the inner side of the protective tube 40.

[0063] In this embodiment, when the vacuum suction cup 16 is well attached to the top surface of the car battery pack and there is no air leakage, the vacuum level in the adsorption unit is normal. At this time, the pressure difference between the upper and lower directions on the sealing structure 41 tends to be balanced: both the lower and upper sides are under stable negative pressure. The design of the support spring 44 inside the protective tube 40 makes the buoyancy or airflow lifting force on the sealing structure 41 balance with its own weight. Therefore, the sealing structure 41 is suspended in the middle of the inner side of the protective tube 40. The sealing structure 41 does not contact the sealing seat 42, and the air passage remains unobstructed, allowing gas to pass through the protective tube 40, the first ventilation slot and the second ventilation slot. The adsorption device 17 can continuously provide negative pressure to the vacuum suction cup 16 through the protective tube 40.

[0064] In this invention, the sealing structure 41 includes a sealing plate 45 detachably connected to the support spring 44 and a sealing block 46 disposed at the center of the upper end of the sealing plate 45. The sealing block 46 has a frustum structure. The sealing seat 42 has an air guide hole that fits with the sealing block 46. The sealing block 46 fits with the air guide hole to seal it, which can seal the sealing seat 42. The second vent groove is formed on the sealing plate 45.

[0065] In this embodiment, when the sealing structure 41 moves upward under force, the sealing plate 45 causes the sealing block 46 to move, so that the sealing structure 41 fits and seals the air guide hole on the sealing seat 42, thus sealing the protective tube 40. The gas path between the adsorption unit and the adsorption device 17 is completely cut off, and the leakage problem no longer affects the overall vacuum system. Other normal units can continue to maintain the adsorption vacuum, ensuring the overall adsorption force is stable.

[0066] In this invention, the lower end face of the sealing seat 42 is vertically arranged with guide rods 47 in a circular array, and the sealing plate 45 is provided with a number of guide holes that match the guide rods 47, so that the guide rods 47 and the guide holes work together to control the sealing block 46 to be aligned and fitted with the sealing seat 42.

[0067] In this embodiment, when the sealing structure 41 is subjected to force and moves upward, the guide rod 47 moves in the guide hole, so that the sealing structure 41 moves in a guiding manner, thus preventing the sealing structure 41 from deviating during the movement and thus failing to seal the sealing seat 42.

[0068] In this invention, a sealing ring 48 is vertically arranged at the upper end of the sealing plate 45 and fits against the outer wall of the sealing seat 42. The sealing plate 45 and the sealing ring 48 work together to improve the sealing effect between the sealing seat 42 and the sealing block 46. Both the sealing block 46 and the sealing ring 48 are hollow structures, thereby reducing the weight of the sealing block 46 and the sealing ring 48.

[0069] In this embodiment, when the sealing plate 45 moves the sealing block 46 upward, the sealing block 46 fits and seals against the sealing seat 42, and the sealing ring 48 fits against the outer wall of the sealing seat 42, thus sealing the sealing seat 42.

[0070] The above embodiments are only used to illustrate the technical methods of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical methods of the present invention without departing from the spirit and scope of the technical methods of the present invention.
