Referring to fig. 1, fig. 1 is a schematic structural diagram of a battery inner pack structure according to an embodiment of the present disclosure. As can be seen from fig. 1, the present application includes a lower case 1 and an upper case 5, wherein a plurality of first partitions 2 are fixedly connected in the lower case 1, and the plurality of first partitions 2 partition an inner space of the lower case 1 into a plurality of battery cavities 3. Referring to fig. 1, a plurality of first separators 2 are arranged at intervals along the length of a lower case 1, thereby dividing the space inside the lower case 1 into a plurality of battery cavities 3 arranged in a single row. In fig. 1, three first partition plates 2 are illustrated, but it should be understood that the specific number of the first partition plates 2 is not particularly limited in the embodiment of the present application, and the required number of the first partition plates 2 may be set according to actual needs, for example, two, four, five, six, and other different numbers of first partition plates 2 are set.

With continued reference to fig. 1, to improve the structural strength of the battery pack structure, at least one first separator 2 among the plurality of first separators 2 is used as the reinforcing structure 4. In a specific arrangement, one of the first partition boards 2 may be used as the reinforcing structure 4, or two or more first partition boards 2 may be used as the reinforcing structure 4. As an example, a first separator 2 located in the middle is employed as the reinforcing structure 4. However, it should be understood that the number of the reinforcing structures 4 is not particularly limited in the present application, and a plurality of reinforcing structures 4 may be provided as necessary.

With continued reference to fig. 1, when one reinforcing structure 4 is employed, the reinforcing structure 4 is located at the central position in the lower case 1, and the remaining first partition plates 2 are symmetrically arranged on the left and right sides of the reinforcing structure 4. So that the reinforcing structure 4 can enhance the structural strength of the entire battery pack structure.

When the batteries are assembled, the battery cores for the shared electric vehicle can be respectively arranged in the battery cavities 3, and the first partition plates 2 separate the battery cores, so that when a certain battery core is damaged, the first partition plates 2 can prevent the influence of the damaged battery cores of other battery cores, and only the battery cores in the damaged battery core battery cavities 3 need to be replaced, and all the battery cores do not need to be replaced like the prior art, so that the replacement cost of the battery cores is reduced, and the operation and maintenance cost of the shared electric vehicle is reduced; the utility model provides a reinforcing structure 4 can strengthen the bulk strength of casing 1 down to can reduce the probability that casing 1 received external force to influence and damage, thereby improve the protection effect to the interior electric core of casing 1 down.

As an alternative, when the first partition plate 2 is provided, an integral structure or a separate structure may be adopted between the first partition plate 2 and the lower case 1. When adopting an organic whole structure, first baffle 2 forms with lower casing 1 an organic whole injection moulding. When the split structure is adopted, the first partition plate 2 may be fixed in the lower case 1 by adhesive bonding. It should be understood that no matter what way the first partition board 2 is connected with the lower housing 1, the first partition board 2 is made of an insulating material, such as rubber, resin, tempered glass, etc.

When casing 1 and last casing 5 lid down, adopt sealed mode to be connected between casing 1 and the last casing 5 down to guarantee the security of battery, avoid when the use rainwater to dip in and damage electric core in the battery endocyst structure. Illustratively, a lower sealing groove 6 is arranged at the opening of the lower shell 1, and an upper sealing groove 7 is arranged at the opening of the upper shell 5. Wherein, lower seal groove 6 encircles the opening of lower casing 1, and upper seal groove 7 encircles the opening of upper casing 5. When the upper shell 5 and the lower shell 1 are closed, the upper sealing groove 7 is opposite to the lower sealing groove 6, and the sealant is filled between the upper sealing groove 7 and the lower sealing groove 6, so that the upper shell 5 and the lower shell 1 are sealed. It should be understood that, when provided, only the upper sealing groove 7 may be provided, and the sealant is filled in the upper sealing groove 7, thereby sealing the upper casing 1 and the lower casing 5; alternatively, only the lower seal groove 6 may be provided, and the sealant may be filled in the lower seal groove 6 to seal the upper case 1 and the lower case 5.

For example, referring to fig. 1, a convex edge is fixedly connected to both the opening of the lower case 1 and the opening of the upper case 5, a lower sealing groove 6 is formed on the convex edge 8 fixedly connected to the opening of the lower case 1, and an upper sealing groove 7 is formed on the convex edge 8 fixedly connected to the opening of the upper case 5. When the upper shell 5 and the lower shell 1 are covered, the two convex edges are opposite, and the upper sealing groove 7 and the lower sealing groove 6 are also opposite. The convex edge increases the arrangement space of the sealing groove (the upper sealing groove 7 or the lower sealing groove 6) on one hand, and also increases the contact area of the upper shell 5 and the lower shell 1 when the upper shell and the lower shell are opposite to the box, thereby increasing the sealing effect of the upper shell and the lower shell when the upper shell and the lower shell are sealed. In addition, the problem of using a sealing ring to age in the prior art is avoided by using the sealing glue, and the service life of the application is prolonged.

During the assembly, put into casing 1 down with the electric core earlier, again inject sealed glue in lower seal groove 6, then buckle upper casing 5 on casing 1 down to make upper seal groove 7 and lower seal groove 6 correspond, thereby couple together lower seal groove 6 and upper seal groove 7 through sealed glue, thereby improve the holistic leakproofness of this application.

In addition, in order to enhance the reliability of the upper case 5 and the lower case 1 at the time of connection, the upper case 5 and the lower case 1 are fixedly connected by bolts.
