Description

Technical Field

[0001] This utility model relates to the field of battery pack hoisting technology, specifically to a battery pack hoisting fixture. Background Technology

[0002] A battery pack is a device that combines multiple individual battery cells to form a single power source. This combination can significantly increase the voltage and / or capacity of the batteries to meet the energy demands of a wide range of applications. Battery packs are widely used in electric vehicles, power tools, uninterruptible power supplies (UPS), energy storage systems, and many other applications requiring portable or stationary power sources.

[0003] During the hoisting and handling of battery packs, appropriate battery pack hoisting fixtures are required. These fixtures use suction cups to hold and secure the battery packs, facilitating hoisting and handling. However, the suction cups on some existing battery pack hoisting fixtures often have fixed positions. When holding different battery pack models, the flatness of the suction cups varies, making it difficult to adjust the suction cup position according to the actual situation of the battery pack. This limits the effectiveness of hoisting and securing different battery pack models. Utility Model Content

[0032] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0033] like Figure 1 , Figure 2 , Figure 3 As shown, a battery pack hoisting fixture includes a mounting frame 1, a mounting plate 2 movably mounted on the mounting frame 1, multiple suction cups 3 fixedly mounted on the mounting plate 2, a fixing mechanism, an adjusting mechanism, and a cleaning mechanism. The hoisting fixture fixes the battery pack by vacuum adsorption using the suction cups 3.

[0034] The fixing mechanism includes a vacuum pump 4 connected to the suction cup 3, which evacuates the suction cup 3 through a pipeline system; the adjusting mechanism includes a telescopic rod 9 that drives the mounting plate 2 to move linearly on the mounting frame 1, and a connecting frame 10 is fixed to the output end of the telescopic rod 9, which is rigidly connected to the mounting plate 2; a guide rod 17 is also provided parallel to the telescopic rod 9, and the guide rod 17 is slidably connected to the connecting frame 10; the cleaning mechanism includes a fan 11 that blows airflow onto the surface of the battery pack, and the fan 11 blows air onto multiple positions on the surface of the battery pack through a diversion pipe 13.

[0035] The overall workflow of this hoisting fixture can be divided into four main stages: positioning, cleaning, adsorption, and hoisting.

[0036] Positioning stage: The device is connected to the lifting equipment via the hanger 15 and the lifting ring 16. The operator controls the lifting equipment to move the tooling above the battery pack. At the same time, the adjustment mechanism is activated to achieve precise linear movement of the mounting plate 2 on the mounting frame 1. The telescopic rod 9 is driven by the motor to rotate the screw structure, converting the rotational motion into linear motion, pushing or pulling the connecting frame 10. The connecting frame 10 is rigidly connected to the mounting plate 2, driving the mounting plate 2 and the suction cup 3 on it to move as a whole. The guide rod 17 is slidably connected to the connecting frame 10, playing a guiding and supporting role, ensuring the stability and accuracy of the mounting plate 2 during movement. Finally, the telescopic rod 9 drives the connecting frame 10 to move, thereby adjusting the position of the mounting plate 2 and the suction cup 3, ensuring that the suction cup 3 can be accurately aligned with the flat area on the surface of the battery pack.

[0037] Cleaning stage: Before the suction cup 3 comes into contact with the surface of the battery pack, the control system starts the fan 11 in the cleaning mechanism. The airflow generated is blown evenly to the surface of the battery pack through multiple air outlets on the diversion pipe 13 to remove surface dust and impurities and ensure the adsorption effect.

[0038] Adsorption stage: When the suction cup 3 contacts the surface of the battery pack, the control system starts the vacuum pump 4 and draws a vacuum inside the suction cup 3 through the pipeline system to form a negative pressure, so that the suction cup 3 is tightly adsorbed on the surface of the battery pack.

[0039] Lifting Phase: Once the system detects that suction cup 3 has reached the preset vacuum level, it sends a lifting signal to the operator. The operator then controls the lifting equipment to lift the fixture, safely hoisting the battery pack and moving it to the designated location. This design can adapt to battery packs of different sizes and shapes. The position of suction cup 3 can be precisely adjusted through an adjustment mechanism. It integrates surface cleaning functions, improving adsorption efficiency and safety. The overall structure is compact and easy to operate.

[0040] As an example, an automatic balancing function can also be added to ensure that the battery pack remains level during hoisting.

[0041] In some embodiments of this utility model, the piping system includes: a bent pipe 5 connected to the outlet of the vacuum pump 4, a horizontal pipe 6 arranged laterally and connected to the bent pipe 5, a flexible hose 7 connecting the horizontal pipe 6 and the suction cups 3, and a connecting pipe 8 fixed to the mounting plate 2 and connected to multiple suction cups 3. The fixing mechanism adopts the principle of vacuum negative pressure, connecting the vacuum pump 4 and multiple suction cups 3 through the piping system to form a closed vacuum circuit. After the vacuum pump 4 is started, it generates negative pressure, which draws out the gas through the bent pipe 5. The airflow passes through the horizontal pipe 6, the flexible hose 7 and the connecting pipe 8 in sequence, and finally draws out the air from inside the suction cups 3. When the suction cups 3 reach a preset vacuum level, the elastic material at the edge of the suction cups 3 forms a seal with the surface of the battery pack, and the battery pack is firmly fixed by the adsorption force generated by atmospheric pressure.

[0042] The layout design of the piping system fully considers the movement requirements of the tooling during adjustment: the bend 5 adopts a 90° bend design to change the airflow direction, allowing the vacuum pump 4 to be installed on the side of the mounting bracket 1, reducing the overall height. The horizontal pipe 6 is arranged laterally as the main air passage, connecting multiple flexible hoses 7. The flexible hoses 7 have a flexible structure, which can adapt to the movement of the mounting plate 2 without affecting the airtightness. The connecting pipe 8 adopts a branch structure design, evenly connecting multiple suction cups 3 to ensure a uniform vacuum level in each suction cup 3.

[0043] In some embodiments of this utility model, the diversion pipe 13 has a serpentine bend structure to ensure that the airflow pressure is evenly distributed at each air outlet. The diversion pipe 13 is connected to the fan 11 through the air duct 12. At least five air outlets are evenly distributed on the surface of the diversion pipe 13. The axis of the air outlet is at an angle of 30°-60° with the surface of the battery pack. The oblique airflow generates shear force and vortex, effectively stripping and blowing away dust and fine particles on the surface of the battery pack. In addition, the air inlet end of the fan 11 is provided with a filter box 14, which contains at least two layers of metal filter screens with different mesh sizes, ranging from 80 to 200 mesh.

[0044] The selection of the air outlet angle is based on fluid dynamics principles; an incident angle of 30°-60° generates sufficient cleaning force while avoiding particle dispersion that might result from direct airflow impact. Evenly distributed air outlets ensure complete coverage of the cleaning area, while the serpentine duct design solves the air pressure distribution problem. This cleaning mechanism design improves the seal between the suction cup 3 and the battery pack surface, reducing vacuum leakage caused by dust. Furthermore, the pre-cleaning process requires no manual intervention, saving operation time and improving work efficiency.

[0045] As an example, an activated carbon filter layer is added to filter harmful gases and odors in the air.

[0046] In some embodiments of this utility model, a hanger 15 is provided on the top of the mounting frame 1. The hanger 15 is connected to the lifting equipment via a rotatable lifting ring 16, the rotation angle range of which is ±90°. The lifting connection structure adopts a rotatable lifting ring design to achieve a safe connection and flexible adjustment between the tooling and the lifting equipment. The hanger 15 is made of high-strength steel and is fixed to the top of the mounting frame 1 by welding or bolting to ensure sufficient load-bearing capacity. The lifting ring 16 is connected to the hanger 15 via a bearing structure and can rotate freely within a range of ±90° to adapt to different lifting angles and directions.

[0047] As an example, the lifting eye 16 is manufactured using a forging process, possessing high strength and toughness. Its inner diameter design takes into account compatibility with common lifting equipment hooks. A sealing structure is provided at the bearing interface to prevent dust and moisture from entering, extending the bearing's service life. Simultaneously, the rotating part of the lifting eye 16 is equipped with a positioning groove, enabling semi-automatic positioning at specific angles (such as 0°, ±45°, ±90°), facilitating operation and adapting to lifting needs under different working conditions.

[0048] As an example, a multi-point lifting design is added, using 2-4 lifting rings 16 distributed on the hanger 15 to improve lifting stability.

[0049] In some embodiments of this invention, the guide rod 17 has a self-lubricating coating on its surface, with a coating thickness of 0.05-0.1 mm and a friction coefficient of less than 0.15. The guide rod 17 is manufactured from high-precision cold-drawn steel, and its surface undergoes precision turning and grinding to ensure surface smoothness and dimensional accuracy. The self-lubricating coating on the surface of the guide rod 17 is a composite material, mainly composed of low-friction coefficient materials such as polytetrafluoroethylene (PTFE) or molybdenum disulfide (MoS2) combined with an epoxy resin substrate. Therefore, the self-lubricating coating has good wear resistance and corrosion resistance, eliminating the need for additional lubricating oil and reducing maintenance.

[0050] In some embodiments of this utility model, the flexible hose 7 is a corrugated metal hose with an axial expansion ratio of 1:1.2-1.5 and a pressure resistance ≥0.8MPa. The flexible hose 7, with its corrugated metal structure design, is a key component connecting the fixed horizontal pipe 6 and the movable connecting pipe 8, ensuring the airtightness and continuity of the vacuum pipeline during the movement of the mounting plate 2. The corrugated metal hose is made of thin-walled stainless steel through a precision forming process, with a corrugated wall structure that allows for an axial expansion ratio of 1:1.2-1.5, adapting to the movement range of the mounting plate 2.

[0051] It is important to note that the corrugated structure design not only provides axial expansion and contraction capabilities but also exhibits a certain degree of lateral bending and torsional adaptability, compensating for minor deviations that may occur during the movement of the mounting plate 2. The smooth inner wall of the flexible hose 7 reduces airflow resistance and improves the efficiency of the vacuum system. An external stainless steel braided mesh sleeve enhances pressure resistance and protective performance. Furthermore, the ends of the flexible hose 7 are designed with flanges or quick-connect fittings to form a reliable connection with the horizontal pipe 6 and the connecting pipe 8. Fluororubber O-rings are used at the sealing points to ensure good sealing performance under expansion, contraction, and vibration conditions. A pressure resistance of ≥0.8 MPa provides ample safety margin for the system.

[0052] In some embodiments of this utility model, the suction cup 3 is made of silicone rubber material, and its edge is provided with an annular protrusion structure with a protrusion height of 2-5mm and a Shore hardness of 50-70HA. It has sufficient softness to ensure good adhesion to the surface of the battery pack, and appropriate hardness to maintain structural stability.

[0053] The suction cup 3 features a bowl-shaped structure with a thinner central area and annular protrusions 2-5mm high at the edges. These protrusions are crucial for creating a seal between the suction cup 3 and the battery pack surface, and their height is designed to accommodate minor unevenness on the battery pack surface. When the vacuum pump 4 is activated, the gas inside the suction cup 3 is extracted, and the annular protrusions deform under atmospheric pressure, pressing firmly against the battery pack surface to form a stable sealing ring. The suction cup 3 also incorporates internal flow channels to ensure rapid air extraction within the entire suction area. Furthermore, the connection points of the suction cup 3 utilize metal inserts for reinforcement, enhancing the connection strength and sealing performance with the connecting tube 8.

[0054] As an example, a support structure is added inside the suction cup 3 to improve stability when adsorbing over a large area.

[0055] In some embodiments of this utility model, the lifting fixture also includes a control system, which comprises: a pressure sensor to monitor the vacuum level inside the suction cup 3 in real time; a displacement sensor to detect the moving distance of the mounting plate 2; and a PLC controller to adjust the operating parameters of the vacuum pump 4 and the telescopic rod 9 based on the sensor feedback signals. The control system is based on the closed-loop control principle, using multiple sensors to monitor the fixture's status in real time, and the PLC controller makes intelligent control decisions.
