Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of vehicle battery structure, in particular to a kind of closed shell for hiding type sealing of vehicle battery. BACKGROUND

[0002] Motorized vehicles generally need to be provided with vehicle batteries to provide power for the vehicle to run or provide power for the vehicle to start. There are two main arrangements for vehicle batteries. One is to directly expose several batteries as a group in the installation position on the vehicle. The other is to place several batteries as a group in a closed shell, and then place the closed shell with batteries in the installation position on the vehicle. In the first arrangement, the safety of the wiring between the batteries mainly depends on the sealing of the installation position on the vehicle. In the second arrangement, the safety of the wiring between the batteries mainly depends on the sealing of the closed shell. For wheeled vehicles such as electric vehicles and motorcycles, due to limited space and cost considerations, the sealing at the installation position is not good, and the safety of the wiring between the exposed batteries is relatively poor. By placing the batteries in the closed shell, the vehicle manufacturer does not pay much attention to the protective measures at the installation position, and the closed shell on the outside of the batteries may be directly exposed to the outside world. The environment of the closed shell is relatively harsh, which puts high requirements on the sealing of the closed shell itself.

[0003] Chinese patent document (publication number: CN 218400828U) discloses a battery pack convenient to disassemble, which comprises an outer shell, a protective cover is sleeved on the outer shell, the protective cover is connected with the outer shell through a locking assembly, the inner side of the outer shell is provided with a partition plate, the partition plate is provided with multiple groups, the multiple groups of partition plates divide the inner side of the outer shell into multiple groups of placement cavities, the inner side of each placement cavity is provided with a hollow placement rack, the inner side of the hollow placement rack is placed with a battery body, both sides of the battery body are provided with elastic sheets, both sides of the elastic sheet are connected with the outer shell and the partition plate, the elastic sheet is arranged in an arc shape and is in contact with the battery body. This kind of battery pack convenient to disassemble cancels the transmission screw fixing mode, adopts a hollow placement rack in the form of insertion, facilitates the installation of the battery body into the outer shell, and the elastic sheet can self-adaptively clamp the battery body and cooperate with the protective cover to fix the battery body, so that when disassembling, the cumbersome steps of disassembling screws are not needed, and the battery body can be pulled out.

[0004] This battery pack discloses a closed shell, which is mainly composed of an outer shell and a protective cover sleeved on the outer shell. To fix the protective cover, a screw needs to pass through the side wall of the protective cover and be connected to the outer shell. Rain and dust from the outside world can easily enter the space between the protective cover and the outer shell through the screw hole in the side wall of the protective cover, and then enter the cavity of the outer shell, thereby affecting the safety of the battery wiring. TECHNICAL PROBLEMS TO BE SOLVED BY THE PRESENT INVENTION

[0005] The present application provides a hidden sealing and closing shell for a vehicle battery, which has good sealing performance and can effectively ensure the safety of the wiring between the batteries.

[0006] To solve the above technical problem, the present application provides a hidden sealing and closing shell for a vehicle battery, which comprises an upper shell and a lower shell, the lower shell has a cavity for accommodating the batteries, a matching part is formed on the upper end of the lower shell, the lower end of the upper shell is used for sleeving the matching part, and a sealing gasket is arranged between the upper shell and the lower shell to realize the sealing of the two shells.

[0007] The upper shell and the lower shell are sleeved and matched, and are connected together by screws or bolts penetrating through the side wall of the upper shell and the lower shell, so that the upper shell and the lower shell are connected as a whole. The inner end of the screw or bolt is generally connected to the bottom surface of the groove. A gap is usually formed between the connecting part and the side wall of the upper shell, and rainwater is easy to enter the gap between the upper shell and the lower shell and enter the groove when it rains.

[0008] Further, the cross section of the groove is in the shape of an inverted U, a U, an inverted C or an inverted V. The inverted U, inverted C and inverted V are arranged in the horizontal direction, and the opening of the groove faces the outside of the lower shell. The groove with these shapes facilitates the collection and flow of collected rainwater, and water vapor is not easy to enter the wiring position of the battery.

[0009] Further, the lower end of the upper shell is located within the height range of the groove, and the lower end of the upper shell has a flow guide opening between the lower side wall of the groove. This makes it difficult for the groove to store water, and the groove only serves to converge the flow, which helps to keep the groove dry and reduces the probability of water vapor entering the wiring position of the battery.

[0010] Further, a protruding compression ring is arranged on the inner side of the upper shell, and the compression ring is used for crimping on the sealing gasket. The crimping of the sealing gasket by the compression ring can effectively improve the sealing effect between the upper shell and the lower shell.

[0011] Further, the upper end of the lower shell is the upper side wall of the groove, and the sealing gasket is arranged on the upper end of the lower shell. The upper end of the lower shell is generally arranged in the horizontal direction and has a relatively large support surface, which facilitates the firm arrangement of the sealing gasket on the upper end of the lower shell.

[0012] Further, the outer edges of both the sealing gasket and the upper side wall of the groove abut against the inner side of the upper shell. This structure is compact and has good sealing between the lower shell and the upper shell.

[0013] Further, a plurality of buffer pads are arranged on the back of the upper shell, and a space is arranged between two adjacent buffer pads. The buffer pads are generally made of sponge, and the arrangement of the buffer pads can improve the stability of the battery in the closed shell.

[0014] Further, a plurality of connecting rings are fixed to the bottom of the groove at positions corresponding to the connecting pieces, and the connecting pieces are correspondingly connected in the connecting rings. The connecting rings are generally welded to the bottom of the groove, so that the connecting rings are arranged horizontally, and the arrangement of the connecting rings prevents the formation of a through hole on the bottom surface of the groove, so that water vapor from the outside cannot enter the lower shell from the position of the connecting pieces.

[0015] Compared with the prior art, the battery closed shell has the following beneficial effects: the battery closed shell includes an upper shell and a lower shell that are sleeved together, a groove is arranged on the matching part at the upper end of the lower shell, a connecting piece for connecting and fixing the upper shell and the lower shell passes through the side wall of the upper shell, and the connecting piece is directly connected to the groove. Therefore, when rainwater from the outside is guided into the groove through the gap between the connecting piece and the side wall of the upper shell, the groove has a converging effect on the rainwater, and the rainwater cannot be guided into the cavity through the capillary effect between the side walls of the upper shell and the lower shell, so that the battery wiring in the closed shell is not affected, and the safety of the battery is good.
