Description

Technical Field

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

[0002] Currently, two main fixture solutions are used in the installation and stacking of battery pack modules for new energy vehicles. The first is to use existing general-purpose industrial equipment for stacking and installing battery pack modules. This type of equipment has the advantage of adjustable width and can accommodate battery pack modules of various widths. The second is to manufacture a simple stacking and installation fixture separately. This solution has the advantages of fast processing speed and low manufacturing cost.

[0003] However, existing technical solutions have many shortcomings. When using general industrial equipment, because these are existing market products, their compatibility with battery pack modules is poor. The battery pack modules are difficult to slide on the equipment, affecting installation efficiency. Simultaneously, the bottom front of the equipment easily interferes with the installation cabinet, requiring the cabinet to be elevated for normal operation, increasing operational complexity. Simple stacking fixtures, on the other hand, use mostly fixed welded parts, and all movement relies on manual operation. This makes them unsuitable for various types of battery pack modules and hinders rapid and efficient installation, severely impacting production efficiency and work quality. Utility Model Content

[0022] The present invention will now be described in more detail with reference to the accompanying drawings, which illustrate preferred embodiments of the present invention. It should be understood that those skilled in the art can modify the present invention described herein while still achieving its advantageous effects. Therefore, the following description should be understood as being broadly known to those skilled in the art and is not intended to limit the present invention.

[0023] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0024] The present invention will be described in more detail below by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become clearer as will be explained below. It should be noted that the drawings are in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0025] This embodiment provides a battery pack module stacking fixture. Please refer to [reference needed]. Figure 1 and Figure 2 It includes: a support unit, a clamping unit, and a drive unit.

[0026] The support unit is used to support and move the entire fixture; the drive unit and the clamping unit are both fixed on the support unit, the clamping unit is used to clamp the battery pack module, and the drive unit is connected to the clamping unit to drive the clamping unit to move along the support unit.

[0027] Specifically, the support unit, as the basic framework of the entire fixture, not only supports other components but also has the ability to move the entire fixture, allowing it to be flexibly transferred to different working positions. The drive unit and the clamping unit are both firmly fixed on the support unit, forming a stable mechanical structure. The clamping unit is specifically responsible for reliably clamping the battery pack module, while the drive unit, through its mechanical connection with the clamping unit, can precisely control the clamping unit to move along a predetermined track or direction of the support unit, thereby achieving precise positioning and movement control of the battery pack module. This design gives the entire fixture the dual functional characteristics of being able to move as a whole and perform precise local operations.

[0028] Furthermore, the support unit includes a base 11 and a support frame 12 disposed perpendicular to the base 11. The support frame 12 is fixed on the base 11 and provides lifting guidance for the clamping unit.

[0029] Specifically, the base 11, serving as the load-bearing foundation of the entire fixture, can be constructed using a welded steel plate structure or cast aluminum alloy, with a preferred thickness of 10-30mm to ensure structural strength. The vertical connection between the support frame 12 and the base 11 includes, but is not limited to, bolted flange fixing, integral casting, and reinforcement using angle steel welding. The support frame 12 can be designed as a rectangular tubular structure or an I-beam structure, with its height determined by the lifting stroke of the battery pack module, typically ranging from 500-1500mm. Guiding functionality is achieved by creating linear guide grooves on the inner side of the support frame 12, with cross-sectional shapes including V-grooves, rectangular grooves, or dovetail grooves.

[0030] By setting up a support frame 12 structure perpendicular to the base 11, the problem of precise vertical positioning of the battery pack module is effectively solved. The support frame 12 not only provides rigid support for the clamping unit, but its built-in guide mechanism also ensures that the clamping unit maintains a stable movement trajectory during lifting, avoiding potential tilting issues during manual operation. This improves the positioning accuracy of the battery pack module during installation. Compared to the welding and fixing method of simple fixtures, the height-adjustable design allows the fixture to adapt to installation requirements at different heights, ensuring operational stability and improving work efficiency.

[0031] Furthermore, the lower surface of the base 11 is provided with casters 111, including omnidirectional casters.

[0032] Specifically, the casters 111 can be made of rubber with a diameter ranging from 100-150mm to balance load-bearing capacity and mobility. The casters are preferably equipped with brakes, which can be foot-operated or manually operated. Alternatively, the casters 111 can be made of polyurethane or nylon, with polyurethane wheels being suitable for scenarios requiring high ground protection. The wheels can be installed using bolts or a quick-release clip structure, which facilitates maintenance and replacement. The number of wheels is typically four, arranged in a rectangular pattern, but can be increased to six to form three sets of support points depending on the size of the base 11.

[0033] By incorporating a moving mechanism with casters, the fixture gains flexible mobility, solving the problem of low operational efficiency caused by inconvenient equipment movement in existing technologies. Specifically, the caster structure allows the fixture to move in multiple directions, avoiding the drawbacks of repeatedly lifting and moving traditional fixed fixtures. Compared to general industrial equipment, the caster configuration is more adaptable to the space constraints of battery pack module installation scenarios, effectively avoiding interference between the equipment and the cabinet. The casters 111 allow operators to easily adjust the fixture's position, achieving precise positioning in confined working spaces, thereby improving the installation efficiency of battery pack modules.

[0034] Furthermore, the base 11 extends away from the clamping unit, and the driving unit includes a driving box 31, which is placed on the base 11 and is used to control the movement of the clamping unit.

[0035] Specifically, the base 11 adopts an extended design, meaning that the base 11 is spatially extended away from the clamping unit. This design provides ample space for the installation of the drive unit. At the same time, the core component of the drive unit, the drive electrical box 31, is specifically located within this extended base 11 area. As the control center of the entire system, the drive electrical box 31 integrates functional modules such as electrical control, signal processing, and power output. It can precisely control and adjust various motion parameters of the clamping unit, including motion speed, position accuracy, and motion trajectory. By arranging the drive electrical box 31 away from the clamping unit, mutual interference between electrical equipment and mechanical moving parts is effectively avoided. It also facilitates the operator to monitor, debug, and maintain the drive electrical box 31. In addition, this separate layout also improves the safety and reliability of the entire fixture system.

[0036] Furthermore, the support frame 12 includes a guide groove 121, and the clamping unit slides and moves up and down along the guide groove 121.

[0037] In this embodiment, the guide groove 121 is a linear groove structure provided on the support frame 12, and can adopt cross-sectional forms such as dovetail groove, T-groove, or rectangular groove. Specifically, the groove width of the guide groove 121 forms a clearance fit with the sliding component of the clamping unit, with the clearance ranging from 0.5 to 2 mm. As a preferred embodiment, a wear-resistant bushing can be provided inside the guide groove 121, and the bushing material is selected from polytetrafluoroethylene or nylon composite material. The length direction of the guide groove 121 is consistent with the extension direction of the support frame 12, and mechanical limiting blocks are respectively provided at its top and bottom to prevent derailment. Further, linear guide rails can be installed on both sides of the guide groove 121, and the clamping unit achieves smooth sliding by cooperating with the guide rails through a slider. The guide groove 121 can be machined by milling or wire cutting processes, and the surface roughness is controlled below Ra1.6.

[0038] The guide groove 121 structure enables precise guiding and lifting of the clamping unit. Specifically, the sliding fit between the guide groove 121 and the clamping unit eliminates lateral displacement deviation, ensuring the positional accuracy of the battery pack module during lifting. Compared with simple jigs operated manually in the prior art, this structure mechanically constrains the movement trajectory of the clamping unit, avoiding the positioning inaccuracies caused by manual operation.

[0039] Furthermore, the clamping unit includes a fixing member 21 and a fork tooth, the fork tooth being movably connected to the fixing member 21 and extending away from the support frame 12, and the fixing member 21 being slidably connected within the guide groove 121.

[0040] Furthermore, the fork teeth include a first fork tooth 22 and a second fork tooth 23, and the distance between the first fork tooth 22 and the second fork tooth 23 is adjustable.

[0041] Furthermore, rollers 24 are provided on the first fork tooth 22 and the second fork tooth 23.

[0042] Specifically, the fork teeth are movably connected to the fixing member 21, allowing the fork teeth to be adjusted in position according to the size of the battery pack module. Specifically, the fork teeth and the fixing member 21 can be movably connected using hinges, slide rails, or telescopic rods. In a preferred embodiment, the fork teeth are hinged to the fixing member 21 via a pivot, allowing the fork teeth to rotate and adjust within a certain angle range. Furthermore, the fork teeth extend away from the support frame 12, facilitating their insertion into the bottom of the battery pack module for clamping operations. The sliding connection between the fixing member 21 and the guide groove 121 can be achieved using a slider and groove mechanism, where the slider is fixed to the fixing member 21, and the groove is located within the guide groove 121 of the support frame 12.

[0043] In this embodiment, the spacing between the two fork teeth is adjustable. As a preferred implementation, adjustment is achieved using a screw drive, with symmetrical movement realized by rotating a handwheel to drive a bidirectional screw. Alternatively, spacing adjustment can also be achieved via an electric push rod, with positioning automatically completed by a command sent from the drive unit 31. In another embodiment, a rack and pinion transmission mechanism is used, with a locking pin enabling rapid switching between fixed positions.

[0044] Therefore, the movable fork design can adapt to the clamping requirements of battery pack modules of different sizes. The sliding connection of the fixing member 21 within the guide groove 121 ensures the stability of the clamping unit's movement, while the extended structure of the fork facilitates effective clamping of the battery pack module. This solves the problem that simple stacking jigs cannot adapt to various types of battery pack modules; the adjustable fork structure improves the jig's versatility and ease of operation. In practice, the angle and extension length of the fork can be adjusted according to actual needs, thereby achieving stable clamping and precise positioning of battery pack modules of different specifications.

[0045] Furthermore, the drive unit includes a hydraulic cylinder 32, which is connected to the fixing member 21. The hydraulic cylinder 32 drives the fixing member 21 to move and drives the fork teeth to move along the support frame 12.

[0046] Furthermore, one end of the hydraulic cylinder 32 is fixed to the base 11, and the other end is provided with a sliding member 41. The fixed member 21 is provided with a support beam 211 on the side away from the fork tooth.

[0047] The drive unit also includes a transmission component 33, which is wound around the sliding component 41. One end of the transmission component 33 is fixedly connected to the fixing component 21, and the other end is fixedly connected to the support beam 211.

[0048] Specifically, the sliding member 41 can be a pulley block or a slider structure, used to change the direction of movement of the transmission member 33. The transmission member 33 is preferably a wire rope or chain, one end of which is connected to the fixing member 21, and the other end is connected to the support beam 211 via an adjusting bolt, facilitating adjustment of the transmission tension. The support beam 211 is a rigid metal component, welded or bolted to the fixing member 21 to enhance structural stability. The piston rod of the hydraulic cylinder 32 is hinged to the sliding member 41, and the cylinder body is fixed to the base 11 via a flange, forming a stable thrust transmission path.

[0049] The sliding member 41 is moved by the hydraulic cylinder 32, which in turn drives the transmission member 33 to pull the fixed member 21 up and down along the support frame 12. Compared with the prior art, the use of hydraulic drive combined with the transmission mechanism solves the problem of low efficiency of manual operation and avoids the defects of poor adaptability of general equipment. The hydraulic system provides a smooth driving force, the combined design of the transmission member 33 and the sliding member 41 realizes the effective transmission of force, and the structure of the support beam 211 enhances the stability of movement, so that the battery pack module maintains precise positioning during the lifting process, improving the reliability and efficiency of the installation operation.
