A roll-formed steel frame battery pack tray Technical Field
[0001] This utility model relates to the field of battery tray technology, specifically a battery pack tray with a roll-formed steel frame. Background Technology
[0002] With the rapid development of the new energy vehicle industry, battery pack trays, as the core load-bearing component of the battery system, directly affect the safety, reliability, and market competitiveness of the entire vehicle through their performance and manufacturing efficiency. Currently, roll-formed steel frame battery pack trays are widely used in the new energy vehicle field due to their high strength, good structural rigidity, and relatively low cost.
[0003] However, in actual production, existing roll-formed steel frame battery pack trays have many inconveniences in assembly. Existing tray designs often include multiple independent components, such as the frame, base plate, and reinforcing ribs. These components need to be assembled and fixed sequentially through welding, bolting, and other methods, which makes the assembly process complex and time-consuming. Therefore, it is necessary to design a roll-formed steel frame battery pack tray to solve the above problems. Summary of the Invention
[0004] The purpose of this invention is to provide a battery pack tray with a roll-formed steel frame to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a battery pack tray with a roll-formed steel frame, comprising a limiting module, a frame module, and a base plate module. The limiting module, the frame module, and the base plate module are stacked sequentially from top to bottom, and each has a corresponding through hole. The three modules can be fixedly connected by connecting pieces passing through the matching through holes in sequence.
[0006] The base plate module is assembled by splicing, and the frame module is also assembled by splicing, and the base plate module can be limited in position.
[0007] Preferably, the base plate module is composed of three sets of base plate bodies of the same specifications spliced together to form a complete base plate. The two adjacent sets of base plate bodies are connected by three sets of pins for limiting. The two ends of the pins can be inserted into the two adjacent sets of base plate bodies respectively to complete the limiting connection of the two adjacent sets of base plate bodies. The frame module is provided on the upper layer of the base plate module.
[0008] Preferably, the frame module includes a long frame and a wide frame. The two sets of long frames are set in the length direction of the base plate, and the two sets of wide frames are set in the width direction of the base plate. The ends of the long frames and the ends of the wide frames are plugged into each other. The wide frames can limit the position of the base plate.
[0009] Preferably, each of the two sets of wide frame edges has a set of baffles integrally formed on opposite sides, and the two sets of baffles can limit and block the length direction of the base plate, thereby limiting the position of the base plate.
[0010] Preferably, the end of the long side frame is provided with a slot, and the end of the wide side frame is integrally formed with a matching plug, and the two can be plugged into each other.
[0011] Preferably, the limiting module is provided on the upper layer of the frame module. The limiting module includes a first limiting member and a second limiting member. Each set of the first limiting members corresponds to a set of base plate bodies, and each set of the second limiting members corresponds to the joint of two sets of base plate bodies.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] 1. Compared with the traditional layer-by-layer assembly method, this utility model adopts a modular design and stacking assembly method, which can directly fix the three components after they are stacked, greatly reducing assembly steps and time and improving assembly efficiency. Since the base plate module and the frame module are both assembled by splicing, when a module is damaged or needs to be replaced, the individual module can be easily disassembled and replaced without replacing the entire tray, thus reducing maintenance costs. The connectors pass through the corresponding through holes of the three components for fastening, which further improves the strength and stability of the overall structure.
[0014] 2. The base plate module of this utility model is composed of three sets of base plate bodies of the same specifications spliced together. This design allows the base plate module to be flexibly adjusted according to actual needs, such as increasing or decreasing the number of base plate bodies to adapt to battery modules of different sizes and shapes. Adjacent sets of base plate bodies are connected by three sets of pins for limiting. This connection method makes the base plate module have higher structural stability after assembly. The limiting effect of the pins effectively prevents relative movement of the base plate bodies during use, improving the reliability of the overall structure. When a base plate body is damaged or needs to be replaced, since the base plate module adopts a splicing assembly form, a single base plate body can be easily disassembled and replaced without replacing the entire base plate module, which greatly reduces maintenance costs.
[0015] 3. The long and wide frames of this utility model are connected by a plug-in splicing method. The end of the long frame has a slot, and the end of the wide frame has a matching plug integrally formed. During installation, the plug at the end of the wide frame is inserted into the slot at the end of the long frame to connect the two and form a complete frame structure. The plug-in splicing method eliminates the need for complicated tools and installation steps. Simply insert the plug of the wide frame into the slot of the long frame to complete the frame assembly, which greatly improves installation efficiency and reduces installation difficulty. Two sets of baffles are located at both ends of the base plate along its length, which can limit and block the base plate in the length direction to prevent it from moving, making the entire structure more stable.
[0016] 4. The frame module and the base plate module of this utility model cooperate with each other to form the placement area of the battery module. The limiting module restricts the movement of the battery module from above, and the first limiting member and the second limiting member can better fit the through holes opened in the base plate module and the frame module, making it convenient to connect with them.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example 1
[0024] Referring to Figures 1-4, this utility model provides a battery pack tray with a roll-formed steel frame, including a limiting module, a frame module, and a base plate module. The limiting module, frame module, and base plate module are stacked sequentially from top to bottom, and each has a corresponding through hole 1. The three modules can be fixedly connected by connecting parts passing through the matching through holes 1 in sequence. The base plate module is assembled by splicing, and the frame module is also assembled by splicing, and the base plate module can be limited.
[0025] First, based on the size and shape of the battery module, the base plate module is assembled. The base plate module serves as the supporting foundation for the battery module, and its assembly design allows for customization according to actual needs. Next, the frame module is also assembled using an assembly method and placed on top of the base plate module. The frame module's assembly also allows for positioning of the base plate module during assembly, ensuring accurate placement. Finally, the positioning modules are stacked on top of the frame modules. These positioning modules are designed to limit the position of the battery module. After all three are stacked, connecting components, including but not limited to bolts, rivets, or special connecting clips, are sequentially passed through the corresponding through holes 1 in the positioning modules, frame modules, and base plate modules to achieve a secure connection. This connection method is simple and quick, greatly improving assembly efficiency.
[0026] Compared to the traditional layer-by-layer assembly method, this utility model adopts a modular design and stacking assembly method, which can directly fix the three components after they are stacked, greatly reducing assembly steps and time and improving assembly efficiency. Since the base plate module and the frame module are both assembled by splicing, when a module is damaged or needs to be replaced, the individual module can be easily disassembled and replaced without replacing the entire tray, thus reducing maintenance costs. The connectors pass through the corresponding through holes of the three components for fastening, further improving the strength and stability of the overall structure.
[0027] Specifically, the base plate module is composed of three sets of base plate bodies 2 of the same specifications spliced together to form a complete base plate. Adjacent sets of base plate bodies 2 are connected by three sets of pins 3 for limiting. The two ends of the pins 3 can be inserted into the two adjacent sets of base plate bodies 2 respectively to complete the limiting connection between the two adjacent sets of base plate bodies 2. A frame module is set on the upper layer of the base plate module.
[0028] The three sets of base plate bodies 2 are custom-made according to design requirements and the dimensions of the battery module. During assembly, the three sets of base plate bodies 2 are spliced together in predetermined positions to form a complete base plate. Adjacent sets of base plate bodies 2 are connected by three sets of pins 3 for limiting their position. The pins 3 are inserted into adjacent sets of base plate bodies 2 to firmly connect them together. The pins 3 not only serve a limiting function but also enhance the overall structural strength of the base plate to a certain extent.
[0029] The base plate module is composed of three identical base plate bodies 2 spliced together. This design allows the base plate module to be flexibly adjusted according to actual needs, such as increasing or decreasing the number of base plate bodies to accommodate battery modules of different sizes and shapes. Adjacent base plate bodies 2 are connected by three sets of pins 3 for limiting. This connection method gives the base plate module higher structural stability after assembly. The limiting function of the pins 3 effectively prevents relative movement of the base plate bodies 2 during use, improving the reliability of the overall structure. When a base plate body 2 is damaged or needs to be replaced, the splicing assembly of the base plate module allows for easy disassembly and replacement of a single base plate body 2 without replacing the entire base plate module, which greatly reduces maintenance costs.
[0030] The frame module includes a long frame 4 and a wide frame 5. The two sets of long frames 4 are set in the length direction of the base plate, and the two sets of wide frames 5 are set in the width direction of the base plate. The ends of the long frames 4 and the ends of the wide frames 5 are plugged in and spliced. The wide frames 5 can limit the position of the base plate. Each of the two sets of wide frames 5 has a baffle 6 integrally formed on the opposite side. The two sets of baffles 6 can limit and block the length direction of the base plate, thereby limiting the position of the base plate. The ends of the long frames 4 are provided with slots 7, and the ends of the wide frames 5 are integrally formed with matching inserts 8. The two can be plugged into each other.
[0031] The long side frame 4 and the wide side frame 5 are connected by a plug-in splicing method. The end of the long side frame 4 has a slot 7, and the end of the wide side frame 5 has a matching plug 8 integrally formed. During installation, the plug 8 at the end of the wide side frame 5 is inserted into the slot 7 at the end of the long side frame 4 to connect the two and form a complete frame structure. The plug-in splicing method eliminates the need for complicated tools and installation steps. Simply insert the plug 8 of the wide side frame 5 into the slot 7 of the long side frame 4 to complete the frame assembly, which greatly improves installation efficiency and reduces installation difficulty. Two sets of baffles 6 are located at both ends of the base plate along its length, which can limit and block the base plate in the length direction to prevent it from moving in the length direction, making the entire structure more stable.
[0032] Among them: the upper layer of the frame module is set with a limiting module, which includes a first limiting member 9 and a second limiting member 10. Each set of first limiting members 9 corresponds to a set of base plate bodies 2, and each set of second limiting members 10 corresponds to the joint of two sets of base plate bodies 2.
[0033] The frame module and the base plate module work together to form the placement area for the battery module. The limiting module restricts the movement of the battery module from above, and the first limiting member 9 and the second limiting member 10 can better fit the through hole 1 opened in the base plate module and the frame module, making it convenient to connect with them.
[0034] Working principle: The three sets of base plate bodies 2 are customized according to design requirements and battery module dimensions. During assembly, the three sets of base plate bodies 2 are spliced together in predetermined positions to form a complete base plate. Adjacent sets of base plate bodies 2 are connected by three sets of pins 3 for limiting. The pins 3 are inserted into adjacent sets of base plate bodies 2 to firmly connect them together. The pins 3 not only serve a limiting function but also enhance the overall structural strength of the base plate to a certain extent. The long side frame 4 and the wide side frame 5 are connected by a plug-in splicing method. The end of the long side frame 4 has a slot 7, and the end of the wide side frame 5 has a matching insert 8 integrally formed. During installation, the wide side frame 5 is... The end plug 8 is inserted into the slot 7 at the end of the long side frame 4 to connect the two and form a complete frame structure. The plug-in splicing method does not require complicated tools and installation steps. Simply insert the plug 8 of the wide side frame 5 into the slot 7 of the long side frame 4 to complete the frame assembly. Finally, the limiting module is stacked on top of the frame module. The limiting module is designed to limit the battery module. After the three are stacked, the connecting parts, including but not limited to bolts, rivets or special connecting buckles, are passed through the corresponding through holes 1 of the limiting module, the frame module and the base plate module in sequence to achieve a tight connection. This connection method is simple and quick, which greatly improves the assembly efficiency.
