Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1 to 6, a battery pack upper cover plate bearing structure includes: an outer bulkhead; the transverse beam and the longitudinal beam are arranged in the outer bulkhead, and the space among the outer bulkhead, the transverse beam and the longitudinal beam can accommodate the battery module; the upper surfaces of the cross beam and the longitudinal beam are higher than the height of the battery module; and the upper cover plate covers the upper surfaces of the cross beams and the longitudinal beams and is connected with the outer cabin wall. When the upper cover plate of the battery pack is directly used for carrying a seat and an upper vehicle body, the upper cover of the battery pack can meet the requirement of treading by a carrying person; the main technical problem that this structure will solve is: (1) how to make the battery package upper cover possess the bearing capacity to the battery package inside electricity core or the module not produce pressure simultaneously. (2) How to reduce the weight of the cross longitudinal beam under the condition that the upper cover plate has enough bearing capacity.
Two groups of cross beams and one group of longitudinal beams are arranged in the outer cabin wall and are uniformly distributed in the outer cabin wall. In the structural aspect: the battery pack is internally supported by a longitudinal beam and two cross beams in a cross beam mode, the heights of the cross beams and the longitudinal beam are higher than those of the module, so that the upper cover plate is directly contacted with the cross beam and the longitudinal beam, and the force received by the upper cover plate during bearing is transmitted to the cross beams and the longitudinal beam, so that the upper cover plate can bear heavy objects.
The inner surface of the upper cover plate is directly contacted with the upper surfaces of the longitudinal beams and the cross beams, and the cross beams are designed into continuous T shapes; the transverse longitudinal beam can not only achieve the capacity of bearing the upper cover plate, but also reduce the self weight and the cost.
The upper cover plate has enough bearing capacity, can protect the safety of the internal battery core and the module, and meets the requirement under the special condition that the upper cover plate is required to bear pressure.
The inside horizontal longitudinal beam height of power battery package surpasss module or electric core height for the upper cover plate can be directly with horizontal longitudinal beam contact, lets module and electric core and upper cover plate have certain buffering space, reaches the bearing effect when guaranteeing module or electric core safety.
The bottom of outer bulkhead is equipped with the bottom plate, and bottom plate and outer bulkhead formula structure as an organic whole, and the structure is more firm reliable.
The edge of the upper cover plate is connected with the outer cabin wall through bolts. A sealing gasket is arranged between the upper cover plate and the connecting surface of the outer cabin wall. The periphery of upper cover plate is equipped with the recess that can hold sealed the pad. The transverse beam and the longitudinal beam are designed in a T shape, the weight is reduced, the module is arranged on two sides of the beam, the upper surface of the T shape is in contact with the inner surface of the upper cover plate, the total area of the upper surface of the T shape is designed to be enough to bear the pressure transmitted from the upper cover plate, the supporting effect is formed, the upper surface of the outer frame is fixed by bolts at the contact position of the upper surface and the upper cover plate, the sealing gasket is used inside to seal, and the sealing effect is guaranteed.
After adopting foretell structure, the inside two crossbeam well word roof beam modes of a longeron of adopting of battery package bear, and crossbeam and longeron height all are higher than the module, make the upper cover plate direct and the contact of horizontal longeron, and the power that receives when bearing the upper cover plate transmits crossbeam and longeron on, makes the upper cover plate reach the ability of bearing the weight of thing.
