Detailed Description
The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to fig. 1 to 9 in the embodiments of the present utility model, and it is obvious that the described embodiments 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 novel efforts, are intended to fall within the scope of this utility model.
In the description of the present utility model, it should be understood that the directions or positional relationships indicated by the terms "upper", "lower", "top surface", "bottom surface", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the indicated positions or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limitations of the present utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Referring to fig. 1 to 9, a first aspect of the present utility model provides a module case 100 for solving a problem of poor sealing caused by deformation due to insufficient strength when a case body 101 is connected to a case cover 102.
As shown in fig. 1 and 2, the module case 100 includes a case body 101, a case cover 102, and a reinforcing member 103, where the top end of the case body 101 is open, and it should be noted that the shape of the case body 101 is not limited, and the case body 101 is a square case body 101, as shown in fig. 3, for example, and other regular or irregular shapes of the case body 101 may be provided. The case 101 and the case cover 102 may be sheet metal members, or may be other material members whose sealing surfaces may be deformed during fastening.
The top end of the box body 101 is provided with a rim sealing plate 101a, and the rim sealing plate 101a is circumferentially arranged around the opening of the top end of the box body 101, i.e. the rim sealing plate 101a is of an annular closed structure. The edge seal plate 101a may extend from the inner wall of the case 101 to the inner cavity of the case 101, or may extend from the outer wall of the case 101 in a direction away from the inner cavity of the case 101.
The case cover 102 covers the case body 101 and is sealingly connected to the top end of the rim sealing plate 101a, and specifically, the case cover 102 and the rim sealing plate 101a are detachably connected by fasteners such as bolts.
The reinforcement member 103 is fixed at the bottom end of the edge sealing plate 101a, and at least completely covers the position where the edge sealing plate 101a is used for connecting the case cover 102, so that the problem of poor sealing caused by local stress deformation of the edge sealing plate 101a when the fastener is installed is avoided.
Specifically, the reinforcement member 103 may be a cast member, and may be made of other materials, so long as the reinforcement member 103 is capable of preventing the edge sealing plate 101a from being deformed due to local stress caused by installing the fastener, which falls within the scope of the present utility model.
The reinforcement 103 may be bonded to the rim seal plate 101a or may be detachably attached by bolts or the like. In order to facilitate the detachment of the reinforcement member 103 from the rim sealing plate 101a, the reinforcement member 103 is detachably connected to the rim sealing plate 101a.
In order to reduce the number of fasteners such as bolts required for the module case 100, the present utility model discloses that the reinforcement 103, the rim sealing plate 101a, and the case cover 102 are detachably connected by fasteners, and the fasteners sequentially pass through the rim reinforcement plate 103a and the rim sealing plate 101a to be fastened to the case cover 102. That is, the same fastener is used for the connection reinforcement 103, the edge sealing plate 101a and the case cover 102 in the present utility model, so that the problem of numerous fasteners caused by using one fastener for connecting the reinforcement 103 and the edge sealing plate 101a and using another different fastener for connecting the edge sealing plate 101a and the case cover 102 is avoided.
Specifically, threaded holes are respectively formed in the reinforcement 103 and the edge sealing plate 101a, and fasteners are screwed into the threaded holes of the reinforcement 103 and the edge sealing plate 101a, so that the edge sealing plate 101a is connected with the reinforcement 103, through holes are correspondingly formed in the case cover 102, and the fasteners penetrate through the through holes and are screwed with the fasteners through nuts so as to press the case cover 102 onto the edge sealing plate 101a. That is, the fastener can position the cover 102 in addition to the function of fastening the cover 102, thereby facilitating the installation of the cover 102.
When the edge sealing plate 101a is thin and a screw hole cannot be formed, the reinforcement 103 may be bonded to the bottom end of the edge sealing plate 101a, a fastener may be screwed to the screw hole of the reinforcement 103, the fastener may pass through the edge sealing plate 101a and the case cover 102, and the case cover 102 may be screwed to the fastener by a nut so as to be pressed against the edge sealing plate 101a.
In some embodiments, the edge sealing plate 101a is formed by bending the top end of the side wall of the box 101 towards the inner cavity of the box 101, and compared with a form of bending the top end of the side wall of the box 101 towards the inner cavity away from the box 101, the occupied area is effectively reduced, and the energy density of the same energy storage system can be effectively increased.
In order to facilitate positioning and installation of the reinforcement 103, the utility model discloses that the reinforcement 103 is placed in the box 101 and is attached to the inner wall of the box 101.
Further, as shown in fig. 4 and 5, the present utility model discloses that the reinforcement member 103 includes a rim reinforcement plate 103a and a corner connection plate 103b, and the number of rim reinforcement plates 103a is plural and is fixed to the bottom ends of the respective sides of the rim sealing plate 101a. Taking the square box body as an example of the box body 101, the edge sealing plate 101a correspondingly has four edges, and the number of the edge reinforcing plates 103a is also 4, and the edge reinforcing plates are respectively arranged in one-to-one correspondence with the edge sealing plate 101a.
The corner connection plates 103b are installed at corners of adjacent sides of the edge sealing plates 101a, and both ends of the corner connection plates 103b are connected to the adjacent edge reinforcing plates 103a, respectively.
It should be noted that, the edge reinforcing plate 103a may be detachably connected to the corner connecting plate 103b, so that the reinforcing member 103 is disposed in the case 101, and the edge reinforcing plate 103a may be detachably connected to the corner connecting plate 103b, not limited to the detachable connection, may be bonded together, and the specific connection mode is not limited.
Specifically, the utility model discloses fasteners respectively connecting the corner connecting plate 103b, the edge reinforcing plate 103a, the edge sealing plate 101a and the box cover 102, and the number of the fasteners is reduced.
Further, the utility model discloses an edge reinforcing plate 103a and a corner connecting plate 103b, wherein one of the edge reinforcing plate 103a and the corner connecting plate 103b is provided with a plug-in protrusion 103b-1, and the other edge reinforcing plate 103a and the corner connecting plate 103b are provided with a plug-in groove 103a-1 for positioning and plugging the plug-in protrusion 103b-1, so that positioning and mounting of the edge reinforcing plate 103a and the corner connecting plate 103b are facilitated.
As shown in fig. 6 and 7, the edge reinforcing plate 103a has insertion grooves 103a-1 at both ends thereof, and the corner connecting plate 103b has insertion protrusions 103b-1 at both ends thereof, which is convenient for manufacturing.
It should be noted that, the shape of the plugging protrusion 103b-1 is adapted to the shape of the plugging groove 103a-1, so as to avoid that a gap exists between the plugging protrusion 103b-1 and the plugging groove 103a-1, which results in poor sealing caused by deformation of the edge sealing plate 101a when the box body 101 and the box cover 102 are connected.
Further, in the edge reinforcing plate 103a and the corner connecting plate 103b, first notches are respectively formed at two ends of one surface facing the edge sealing plate 101a to form a first step 103a-2; the other two ends of the surface facing away from the edge sealing plate 101a are respectively provided with a second notch to form a second step 103b-2. The second step 103b-2 is lapped on the first step 103a-2, and the first step 103a-2 is abutted against the end of the second step 103b-2, so that poor sealing caused by deformation of the edge sealing plate 101a due to clearance is avoided.
Taking the example that two ends of the edge reinforcing plate 103a are respectively provided with a first notch and two ends of the corner connecting plate 103b are respectively provided with a second notch. The insertion groove 103a-1 is provided at one end of the first step 103a-2 of the edge sealing plate 101a away from the edge reinforcing plate 103a, and the insertion protrusion 103b-1 is provided on the step surface of the second step 103b-2 at one end close to the corner connecting plate 103 b.
In some embodiments, as shown in fig. 8 and 9, the module case 100 further includes a gasket 104, and the gasket 104 is disposed between the case cover 102 and the rim sealing plate 101a to seal the case cover 102 and the rim sealing plate 101a. The seal ring 104 is an annular seal ring 104.
Further, the sealing ring 104 is located at one side of the fastening piece close to the inner cavity of the box body 101, so that liquid caused by the fact that the sealing ring 104 is located at one side of the fastening piece far away from the inner cavity of the box body 101 is prevented from penetrating into the inner cavity of the box body 101 along the fastening piece.
Specifically, the gasket 104 may be bonded to the cover 102 or the rim seal 101a.
In some embodiments, a connector 105 is provided on the housing 101 to electrically connect an external connector.
