Description

Technical Field

[0001] The utility model relates to the technical field of battery trays, in particular to a lightweight battery tray structure. Background Art

[0002] Solid-state lithium battery technology uses glass compounds made of lithium and sodium as conductive materials to replace the electrolyte of previous lithium batteries, greatly improving the energy density of lithium batteries. The battery pack is an energy storage component equipped with battery modules on electric vehicles and is the core component of electric vehicles. The battery tray is the main frame structure of the battery pack and bears the weight of the battery module. Its structure and heat dissipation performance have an important impact on the performance and service life of the battery pack, and are directly related to the performance and safety of electric vehicles.

[0003] When the existing battery tray is in use, it is usually a single aluminum alloy structure. The weight between the tray and the battery is heavy, which affects the endurance of the electric vehicle. In addition, when disassembling and maintaining the battery pack, the operation is not convenient due to its heavy weight. For this reason, we propose a lightweight battery tray structure. Utility Model Content

[0004] In view of the above problems, the utility model provides a lightweight battery tray structure, which can solve the problems existing in the above background technology.

[0005] The technical solution of the utility model is:

[0006] A lightweight battery tray structure comprises a reduced-thickness tray body, a battery body is placed on the inner side of the top of the reduced-thickness tray body, mounting feet are symmetrically provided on the top of the front and rear surfaces of the reduced-thickness tray body, protective mechanisms are movably connected on both sides of the reduced-thickness tray body, and fastening bolts are movably connected between the protective mechanism and the reduced-thickness tray body.

[0007] In a further technical solution, the protective mechanism includes a first connecting plate and a second connecting plate, the inner sides of the first connecting plate and the second connecting plate are fixedly connected with a connecting base plate and a fixed connecting plate, and a reinforcing support block is fixedly connected between the connecting base plate and the fixed connecting plate.

[0008] In a further technical solution, first threaded holes are formed at both ends of the reduced-thickness tray body, and second threaded holes are formed on the surfaces of the first connecting plate and the second connecting plate.

[0009] In a further technical solution, fixed limiting blocks are symmetrically provided at both ends of the reduced-thickness tray body, and fixed slots are symmetrically provided on the inner sides of the first connecting plate and the second connecting plate.

[0010] In a further technical solution, the cross-sectional shape of the reinforcing support block is X-shaped, the number of the reinforcing support blocks is several, and the several reinforcing support blocks are equidistantly located between the connecting bottom plate and the fixed connecting plate.

[0011] In a further technical solution, the inner sides of the first connecting plate and the second connecting plate are in contact with the two end surfaces of the reduced-thickness tray body.

[0012] In a further technical solution, the cross-sectional shapes of the fixing slot and the fixing limiting plug-in block are both T-shaped, and the inner side of the fixing slot and the outer side of the surface of the fixing limiting plug-in block fit each other.

[0013] The beneficial effects of the utility model are:

[0014] 1. The protective mechanism can protect the reduced pallet body after the reduced pallet body itself is reduced in weight, so that the reduced pallet body can be used stably, so as to ensure that when the reduced pallet body is in use, the mounting feet located inside the reduced pallet body can be used stably. At the same time, when disassembling, the protective mechanism can be disassembled first, and then the reduced pallet body can be disassembled, which is convenient and quick to operate;

[0015] 2. The fixed slots and fixed limit blocks can be used to perform preliminary positioning between the thickness reduction tray body and the protective mechanism. This can also prevent shaking between the thickness reduction tray body and the protective mechanism, which would otherwise damage the fastening bolts when subjected to force. This allows the overall connection to be in a stable state, making operation easy. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0022] Example:

[0023] like Figure 1-Figure 3 As shown, a lightweight battery tray structure includes a reduced-thickness tray body 1, a battery body 2 is placed on the inner side of the top of the reduced-thickness tray body 1, mounting feet 3 are symmetrically provided on the top of the front and rear surfaces of the reduced-thickness tray body 1, protective mechanisms 4 are movably connected on both sides of the reduced-thickness tray body 1, and fastening bolts 5 are movably connected between the protective mechanism 4 and the reduced-thickness tray body 1.

[0024] The working principle of the above technical solution is as follows:

[0025] The reduced-thickness pallet body 1 and the protective mechanism 4 can be conveniently connected and fixed by tightening the bolts 5. While the reduced-thickness pallet body 1 itself reduces its weight, the protective mechanism 4 can provide protection for the reduced-thickness pallet body 1, so that the reduced-thickness pallet body 1 can be used stably. At the same time, when disassembling, the protective mechanism 4 can be disassembled first to reduce the overall weight, and then the reduced-thickness pallet body 1 can be disassembled. The operation is convenient and quick.

[0026] In another embodiment, if Figure 3 As shown, the protection mechanism 4 includes a first connecting plate 7 and a second connecting plate 11, the inner sides of the first connecting plate 7 and the second connecting plate 11 are fixedly connected with a connecting bottom plate 8 and a fixed connecting plate 10, and a reinforcing support block 9 is fixedly connected between the connecting bottom plate 8 and the fixed connecting plate 10.

[0027] The first connecting plate 7 and the second connecting plate 11 can fit together with the outer sides of the two end surfaces of the reduced-thickness pallet body 1, so that the top of the fixed connecting plate 10 fits together with the bottom of the reduced-thickness pallet body 1. The reinforcing support block 9 can be used to connect the bottom plate 8 and the fixed connecting plate 10 for reinforced support, thereby providing stable protection for the reduced-thickness pallet body 1 and facilitating use.

[0028] In another embodiment, if Figure 2 and Figure 3 As shown, first threaded holes 6 are formed at both ends of the reduced-thickness tray body 1 , and second threaded holes 12 are formed on the surfaces of the first connecting plate 7 and the second connecting plate 11 .

[0029] It is convenient to quickly connect and fix the pallet body 1 and the first connecting plate 7 and the second connecting plate 11 through the fastening bolts 5 .

[0030] In another embodiment, if Figure 2 and Figure 3As shown, fixed limiting inserts 14 are symmetrically provided at both ends of the reduced-thickness tray body 1 , and fixed slots 13 are symmetrically provided on the inner sides of the first connecting plate 7 and the second connecting plate 11 .

[0031] When assembling the pallet body 1 with the first connecting plate 7 and the second connecting plate 11, the first connecting plate 7 and the second connecting plate 11 can be sleeved on the outer surface of the fixed limiting block 14 under the action of the fixed slot 13, so as to perform preliminary connection limiting.

[0032] In another embodiment, if Figure 3 As shown, the cross-sectional shape of the reinforcing support block 9 is X-shaped, and there are a plurality of reinforcing support blocks 9 , which are equidistantly located between the connecting bottom plate 8 and the fixed connecting plate 10 .

[0033] The strengthening support block 9 can stably support the connection bottom plate 8 and the fixed connection plate 10, thereby improving the overall use strength.

[0034] In another embodiment, if Figure 3 As shown, the inner sides of the first connecting plate 7 and the second connecting plate 11 are in contact with the two end surfaces of the reduced-thickness tray body 1 .

[0035] The first connecting plate 7 and the second connecting plate 11 are in a stable connection state with the reduced-thickness pallet body 1 , so that the whole can be used stably.

[0036] In another embodiment, if Figure 2 and Figure 3 As shown, the cross-sectional shapes of the fixing slot 13 and the fixing limiting insert block 14 are both T-shaped, and the inner side of the fixing slot 13 and the outer side of the surface of the fixing limiting insert block 14 fit each other.

[0037] The first connecting plate 7 and the second connecting plate 11 are connected and matched with the reduced-thickness tray body 1 through the fixed slots 13 and the fixed limiting inserts 14 , thereby improving the connection stability.

[0038] The working principle of the utility model is as follows: during use, the first connecting plate 7 and the second connecting plate 11 are fitted on the outer side of the two end surfaces of the thickening tray body 1, and are sleeved on the outer side of the surface of the fixed limiting plug block 14 under the action of the fixing slot 13, so that the top of the fixed connecting plate 10 and the bottom end of the thickening tray body 1 are fitted with each other, and then the fastening bolt 5 is rotated and inserted into the inner side of the second threaded hole 12 and the first threaded hole 6 to connect and fix the thickening tray body 1 and the protective mechanism 4 as a whole. The mutual cooperation between the fixing slot 13 and the fixed limiting plug block 14 can effectively prevent the first connecting plate 7 and the second connecting plate 11 from shaking with the thickening tray body 1, causing damage to the fastening bolt 5, and can also improve the overall connection stability. When disassembly and maintenance are required, the fastening bolt 5 can be rotated and disassembled first, thereby disassembling the protective mechanism 4 as a whole, and then the thickening tray body 1 can be disassembled after reducing a certain weight. The structure is simple and easy to use.

[0039] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
