Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Referring to fig. 1 to 6, a battery pack upper and lower cover plate structure of a common mold has:
the device comprises a bottom plate 1, a frame 2 and an upper box body 3, wherein the bottom plate 1 is connected with the bottom of the frame 2, and the bottom of the upper box body 3 is connected with the upper end of the frame 2; a box body is formed for installing the battery cell.
The same reinforcing rib structure is arranged on the bottom plate 1 and the upper box body 3; the rib pressing structure of the upper cover plate and the lower cover plate can be used for the die, so that the utilization rate of the die is improved, and the development and the period of the die are reduced.
The strengthening rib structure includes: the concave table 11 is arranged on the bottom plate 1, and the concave table 11 is close to the periphery of the bottom plate 1; a series of longitudinal bosses 12 are arranged in the length direction of the concave table 11; a transverse boss 13 connected to a series of longitudinal bosses 12; the transverse concave ribs 14 are arranged in the length direction of the transverse boss 13. The strength of the upper case cover and the lower case cover is enhanced, the overall mode and the rigidity are ensured, and the abnormal sound risk is reduced.
The depth of the recess 11 is greater than the height of the bolt head. The depth of the stamping structure can protect the position of the bolt head; the problem of airtight is avoided because of the bearing of the lower sealing bolt.
The periphery of the base plate 1 and the upper case 3 are provided with a series of bolt holes 4. The upper box body 3 is connected with the frame 2 through bolts, and the contact surface of the upper box body 3 and the frame 2 is sealed through a sealing strip.
The frame 2 is also provided with a series of lifting lugs which play a role in connection with the vehicle.
The frame 2 comprises four steel beams which are mutually spliced and welded. In the actual manufacturing process, half of the welding is resistance welding and half of the welding is section welding, so that the welding workload is greatly reduced, the requirement on welding quality is reduced, the working efficiency is improved, and the product quality is improved.
The implementation process comprises the following steps:
1. determining the module layout, so that the positions of the reinforcing ribs of the lower bottom plate are in one-to-one correspondence;
2. determining the size of the bolt head, so that the depth of the stamping structure can protect the position of the bolt head;
3. unifying the structural design of the upper cover plate and the lower cover plate, and verifying whether the inner cavity size of the upper cover plate and the gap between the modules meet the requirements.
The technical key point is that a unified stamping characteristic design is adopted; a design that exceeds the height dimension of the sealing bolt head; through size matching and welding position matching, the air tightness is guaranteed, the strength of a single piece is enhanced, the rigidity of the whole bag is finally improved, and the working efficiency and the product quality are improved.
After the structure is adopted, 1, the strength of the upper cover plate and the lower cover plate of the battery pack is enhanced; 2. the problem of air tightness caused by bearing of the lower sealing bolt is avoided; 3. and the mold is reasonably utilized, so that the development cost and the period of the mold are reduced.
