The gasket 13 is likely to expand after the bolt fastening, so that the upper cover 12 is largely warped at its edge, resulting in poor sealing between the battery pack and the vehicle body. Referring to fig. 2, in the second structure, the edge of the upper cover 22 is bent toward the side close to the case 21, so that the edge of the upper cover 22 is somewhat relieved from warping, but occupies a large peripheral space.
In summary, in the conventional battery pack case structure, the upper cover is prone to generate large edge warpage, which results in poor sealing or occupies a large peripheral space.
SUMMERY OF THE UTILITY MODEL
The utility model provides a battery package box structure, battery package and vehicle can avoid the upper cover warpage to reduce the space simultaneously and occupy, reaches stable sealed effect.
In order to solve the technical problem, the utility model provides a battery package box structure, including casing and upper cover, the casing is close to one side of upper cover is equipped with the bellying, the upper cover with bellying looks butt, the bellying with the casing is connected and is formed the mounting groove that is used for holding the sealing washer.
Preferably, the boss is provided at a top edge of the housing.
Preferably, the side wall of the boss abuts against one side of the sealing ring.
Preferably, the height of the protrusion is equal to the thickness of the sealing ring.
Preferably, the housing is integrally formed with the boss.
Preferably, a sealing strip is arranged above the upper cover and used for sealing the battery pack and the vehicle body.
Preferably, the upper cover is fixedly connected with the housing through bolts.
The utility model also provides a battery package, include as above-mentioned content arbitrary one battery package box structure.
The utility model also provides a vehicle, include as above-mentioned content battery package.
Compared with the prior art, the utility model discloses following beneficial effect has:
the utility model provides a battery package box structure, including casing and upper cover, the casing is close to one side of upper cover is equipped with the bellying, the upper cover with bellying looks butt, the bellying with the casing is connected and is formed the mounting groove that is used for holding the sealing washer. After the upper cover is fixed, the problem of warping of the upper cover caused by expansion of the sealing ring can be avoided due to the limitation of the bulge, and a stable sealing effect is achieved. Simultaneously, the edge of upper cover need not to set up buckles, does not occupy the exterior space, can effectively reduce the tolerance accumulation of this department, promotes space utilization. In addition, the bulge part can play a role in positioning the sealing ring, so that the sealing ring is convenient to mount.
Drawings
FIG. 1 is a schematic cross-sectional view of a prior art battery pack case;
fig. 2 is a schematic cross-sectional view of another prior art battery pack case;
fig. 3 is a schematic cross-sectional view of a battery pack case structure provided by an embodiment of the present invention.
Wherein the reference numbers are as follows: 3. a housing; 31. a boss portion; 32. a nut; 4. an upper cover; 5. a seal ring; 6. a bolt; 7. a sealing strip; 8. a vehicle body.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the 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 efforts belong to the protection scope of the present invention.
Referring to fig. 3, the embodiment of the present invention provides a battery pack box structure including casing 3 and upper cover 4, casing 3 is close to one side of upper cover 4 is equipped with bellying 31, upper cover 4 with bellying 31 looks butt, bellying 31 with casing 3 is connected and is formed the mounting groove that is used for holding sealing washer 5.
In this embodiment, the protrusion 31 is disposed at the top edge of the housing 3, and the protrusion 31 is a step-shaped protrusion on the top of the housing 3. Illustratively, the housing 3 is integrally formed with the boss 31. Of course, the housing 3 and the boss 31 may be welded or screwed.
Wherein the bottom of the mounting groove is a part of the top of the housing 3, and the right side wall of the boss 31 constitutes the side wall of the mounting groove. When the sealing ring 5 is installed, the side wall of the bulge 31 is abutted against one side of the sealing ring 5, and the bulge 31 can play a role in positioning the sealing ring 5, so that the installation of the sealing ring 5 is facilitated.
Preferably, the height of the projection 31 is equal to the thickness of the sealing ring 5. After the upper cover 4 is fixed, the problem of edge warping of the upper cover 4 caused by expansion of the sealing ring 5 can be avoided due to the limitation of the convex part 31, and a stable sealing effect is achieved.
In a specific implementation, the upper cover 4 is fixedly connected with the housing 3 through a bolt 6. The upper cover 4 is provided with a through hole, the shell 3 is internally provided with a nut 32, and the bolt 6 passes through the upper cover 4 and the sealing ring 5 to be fixedly connected with the nut 32. Compared with the prior art, the edge of the upper cover 4 in the embodiment does not need to be bent, the external space is not occupied, the tolerance accumulation at the position can be effectively reduced, and the space utilization rate is improved.
In this embodiment, a sealing strip 7 is disposed above the upper cover 4, and the sealing strip 7 is used for sealing the battery pack and the vehicle body 8. The sealing strip 7 is arranged on the battery pack, and achieves the sealing effect with the vehicle body 8 through a certain compression amount. Wherein, the battery package can adopt CTB (Cell to Body, battery automobile Body 8 integration) technique, and sealing strip 7 is used for realizing the sealed between battery package and automobile Body 8 to cancel the automobile Body floor.
To sum up, the battery pack box structure that this embodiment provided, after upper cover 4 is fixed, because the restriction of bellying 31, can avoid because of the upper cover 4 edge warpage problem that sealing washer 5 inflation leads to, reach stable sealed effect. Meanwhile, the edge of the upper cover 4 does not need to be bent, the external space is not occupied, the tolerance accumulation at the position can be effectively reduced, and the space utilization rate is improved. Furthermore, the boss 31 can function as a positioning of the seal ring 5, facilitating the installation of the seal ring 5.
This embodiment also provides a battery pack, which includes the battery pack case structure according to any one of the above embodiments.
The embodiment also provides a vehicle comprising the battery pack according to the above embodiment. The vehicle may be a hybrid vehicle, an electric vehicle, or the like.
