[0029] Electric vehicles usually have two-wheel drive and four-wheel drive configurations. Two-wheel drive refers to the front motor driving the vehicle or the rear motor driving the vehicle, and four-wheel drive refers to the four wheels of the vehicle can receive power, including the situation where the vehicle is driven by both the front and rear motors. Correspondingly, the battery box of the battery needs to be equipped with a spare plug interface corresponding to the motor adapter. The front-wheel drive model requires the battery box to have a spare plug interface on the front frame plate, and the rear-wheel drive model requires the battery box to have a spare plug interface on the rear frame plate. If the four-wheel drive model is driven by both the front and rear motors, spare plug interfaces need to be reserved on the front and rear frames of the battery box.

[0030] In order to make the battery box suitable for front-wheel drive vehicles, rear-wheel drive vehicles and four-wheel drive vehicles, the embodiment of the present application provides a battery plug connector to increase the applicability of the battery box to different drive vehicle models.

[0031] Below through Figures 1 to 4The battery plug connector of the embodiment of the present application is described in detail.

[0032] like Figures 1 to 4 As shown, the present application provides a battery plug connector 20, which is used to be plugged into a spare plug interface 101 of a battery box 10. The battery plug connector 20 includes a plug body 21 and a sealing plug 22. The first end of the plug body 21 is provided with a first plug interface that is plugged into the spare plug interface 101, and the second end of the plug body 21 is provided with a second plug interface that can be plugged into an electrical device; the sealing plug 22 is configured to be detachably connected to the second plug interface.

[0033] In this embodiment, the battery plug connector 20 provided in the embodiment of the present application can cooperate with the spare plug interface 101 of the battery box 10. When the battery box 10 needs to be connected to an electrical device, the sealing plug 22 is removed from the second plug interface, and the battery plug connector 20 is connected to the electrical device through the second plug interface; when the battery box 10 does not need to be connected to an electrical device, the sealing plug 22 is plugged into the second plug interface, so that the battery box 10 can be provided with a plurality of spare plug interfaces 101 corresponding to a variety of usage scenarios, thereby improving the applicability of the battery box 10 to different usage environments and different drive vehicle models.

[0034] Specifically, the plug-in body 21 serves as the male end, and the spare plug interface 101 of the battery box 10 serves as the female end, and the two are plugged in; the sealing plug 22 is assembled at the tail of the plug-in body 21 to seal and prevent external water and dust from entering the interior of the battery box 10 through the plug-in body 21.

[0035] By reserving spare plug interfaces 101 on the front and rear frame plates of the battery box 10, the battery 100 can be adapted to front-wheel drive vehicles, rear-wheel drive vehicles and four-wheel drive vehicles. For front-wheel drive vehicles using a front-wheel drive motor, the spare plug interface 101 of the front frame plate 11 of the battery box 10 and the plug body 21 of the battery plug connector 20 are used to power the front-wheel drive motor, and at the same time, the spare plug interface 101 of the rear frame plate 12 is blocked with the sealing plug 22 of the battery plug connector 20; for rear-wheel drive vehicles using a rear-wheel drive motor, the spare plug interface 101 of the rear frame plate 12 of the battery box 10 and the plug body 21 of the battery plug connector 20 are used to power the rear-wheel drive motor, and at the same time, the spare plug interface 101 of the front frame plate 11 is blocked with the sealing plug 22 of the battery plug connector 20; for four-wheel drive vehicles using front and rear two drive motors, the spare plug interfaces 101 of the front and rear frame plates are connected to the high-voltage wiring harness through the plug body 21 of the battery plug connector 20, so as to power the front and rear two drive motors.

[0036] In addition, it should be noted that the embodiment of the present application does not limit the specific structure of the plug body 21 and the sealing plug 22, because the main improvement point of the embodiment of the present application is to assemble the battery plug connector 20 to the spare plug interface 101 of the battery box 10, and the battery plug connector 20 can achieve the purpose of connecting to the spare plug interface 101 and sealing the spare plug interface 101. As for the specific structure of the plug body 21 and the sealing plug 22, it includes a variety of embodiments, and the preferred embodiments of the specific structure of the plug body 21 and the sealing plug 22 will also be explained below.

[0037] The specific implementation of the battery plug connector is described below through the preferred embodiments of the present application.

[0038] like Figures 1 to 4 As shown, in some embodiments, the sealing plug 22 includes a sealing cover 221 and a sealing gasket 222. The sealing cover 221 has an accommodating cavity formed inside for accommodating the second plug interface of the plug-in body 21. The sealing gasket 222 is disposed in the accommodating cavity and covers the second plug interface.

[0039] In this embodiment, by covering the second plug interface of the plug body 21 with a sealing cover 221, it is possible to reduce the entry of external fixed particles into the interior of the plug body 21. By sealing the gap between the sealing cover 221 and the second plug interface of the plug body 21 with a sealing gasket 222, it is possible to reduce the entry of external water vapor or air into the interior of the plug body 21. By cooperating with the sealing cover 221 and the sealing gasket 222, the purpose of sealing the second plug interface of the plug body 21 can be achieved.

[0040] like Figures 1 to 4 As shown, in some embodiments, the sealing plug 22 further includes a stopper 223 , which is fixed to the accommodating cavity of the sealing cover 221 and is located on the outside of the sealing gasket 222 .

[0041] In this embodiment, after the sealing gasket 222 is assembled into the accommodating cavity of the sealing cover 221 , the stopper 223 can limit the sealing gasket 222 , thereby reducing the phenomenon of the sealing gasket 222 falling off or shaking.

[0042] Furthermore, the stop member 223 is directly in contact with the second plug interface of the plug-in body 21. The stop member 223 can protect the second plug interface of the plug-in body 21 and reduce the phenomenon of damage to the second plug interface of the plug-in body 21. In addition, the stop member 223 is configured to be made of a flexible material. The stop member 223 can also be deformed during the plug-in process of the plug-in body 21, thereby increasing the plug-in amount of the plug-in body 21 inside the sealing plug 22.

[0043] like Figures 1 to 4As shown, in some embodiments, the stopper 223 and / or the sealing cover 221 are configured as a hollow structure, and the sealing gasket 222 is configured to at least cover the hollow portion of the stopper 223 and / or the sealing cover 221 .

[0044] In this embodiment, the stopper 223 and / or the sealing cover 221 are configured as hollow structures, so that the weight of the sealing plug 22 and the battery plug connector 20 can be reduced, and the consumption of materials can be reduced. At the same time, the hollow part of the stopper 223 and / or the sealing cover 221 is sealed by the sealing gasket 222, so that the phenomenon of external dust and water vapor entering the interior of the battery plug connector 20 through the hollow part of the stopper 223 and / or the sealing cover 221 is reduced.

[0045] like Figures 1 to 4 As shown, in some embodiments, the shape of the second plug interface of the plug body 21 is set to be a Japanese-shaped opening, a Chinese-shaped opening, or a Chinese-shaped opening, and the shape of the stopper 223 is set to be consistent with the shape of the second plug interface.

[0046] In this embodiment, by setting the shape of the stop member 223 to be consistent with the shape of the second plug interface, on the one hand, the purpose of saving materials can be achieved, and on the other hand, the stop member 223 can be made to contact the periphery of the second plug interface, so that the stop member 223 only contacts the periphery of the sealing gasket 222, thereby reducing the resistance of the sealing gasket 222 to the stop member 223 and the plug-in body 21, so that the plug-in body 21 can extend into the interior of the sealing cover 221 to a greater extent, thereby improving the sealing effect of the sealing cover 221 on the plug-in body 21.

[0047] like Figures 1 to 4 As shown, in some embodiments, a buckle is provided on the inner side of the sealing gasket 222, and a slot cooperating with the buckle is provided on the bottom of the sealing cover 221, and the sealing gasket 222 is suitable for being plugged into the sealing cover 221 through the buckle.

[0048] In this embodiment, during the process of assembling the sealing cover 221 and the sealing gasket 222, the sealing gasket 222 is suitable for being plugged into the sealing cover 221 through a snap, so as to achieve the purpose of limiting and fixing the sealing cover 221 and the sealing gasket 222, and reduce the phenomenon of the sealing gasket 222 falling off during the use of the battery connector 20.

[0049] like Figures 1 to 4 As shown, in some embodiments, the inner wall of the sealing cover 221 is provided with a groove 2211, and the outer wall of the plug-in body 21 is provided with a snap-fit ​​protrusion 211 that can cooperate with the groove.

[0050] In this embodiment, during the process of assembling the sealing cover 221 and the plug-in body 21, the groove 2211 of the sealing cover 221 and / or the snap-in protrusion of the plug-in body 21 are deformed, so that the groove 2211 of the sealing cover 221 can be snapped into the snap-in protrusion 211 of the plug-in body 21, thereby achieving the purpose of limiting and fixing the sealing cover 221 and the plug-in body 21, and reducing the phenomenon of the sealing cover 221 falling off or shaking during the use of the battery plug connector 20.

[0051] Specifically, the sealing cover 221 and / or the plug-in body 21 are made of flexible material or elasticity. During the assembly process of the sealing cover 221 and the plug-in body 21, the sealing cover 221 and / or the plug-in body 21 can undergo slight deformation, so that the groove 2211 of the sealing cover 221 can reach the position of the snap-in protrusion of the plug-in body 21 and snap-fit ​​with the snap-in protrusion 211 of the plug-in body 21.

[0052] like Figures 1 to 4 As shown, in some embodiments, the snap-fit ​​protrusion 211 is configured to be composed of an elastic pressing sheet, and the elastic pressing sheet is configured to be able to extend out of the sealing cover 221 through the groove 2211 .

[0053] In this embodiment, by setting the clamping protrusion 211 to be composed of an elastic pressing piece, it is convenient for users to disassemble and assemble the sealing cover 221. Specifically, when the user assembles the sealing cover 221 to the plug-in body 21, the sealing cover 221 squeezes the elastic pressing piece to deform, so that the sealing cover 221 can be assembled to the predetermined position of the plug-in body 21. At this time, the groove 2211 of the sealing cover 221 is located at the elastic pressing piece of the plug-in body 21, and the elastic pressing piece extends from the groove 2211 of the sealing cover 221, which plays a limiting role for the sealing cover 221; when the user needs to disassemble the sealing cover 221, the user only needs to press the elastic pressing piece to make the elastic pressing piece come out of the groove 2211. At this time, the sealing cover 221 loses the constraint of the elastic pressing piece, and the user can remove the sealing cover 221 from the plug-in body 21.

[0054] like Figures 1 to 4 As shown, in some embodiments, the second plug interface of the plug body 21 is set to a Japanese-shaped opening, a Chinese-shaped opening or a Chinese-shaped opening, and the outer wall of the sealing cover 221 is provided with a contoured plug interface that contours the second plug interface.

[0055] In this embodiment, the plug-in body 21 is connected to the plug connector of the external electrical device through the second plug interface. In order to enable the user to intuitively select the plug connector compatible with the plug-in body 21, the embodiment of the present application proposes that the outer wall of the sealing cover 221 is provided with a contoured plug interface that conforms to the second plug interface. Therefore, when the sealing cover 221 covers the second plug interface of the plug-in body 21, the user can check the type of the second plug interface of the plug-in body 21 through the sealing cover 221, and then select the plug connector compatible with the plug-in body 21, so that the external electrical device can be effectively connected to the battery 100.

[0056] A second aspect of the present application provides a battery 100 , which includes a battery box 10 and a battery plug connector 20 as in the first aspect of the present application, wherein the battery plug connector 20 is adapted to be plugged into a spare plug port 101 of the battery box 10 .

[0057] In this embodiment, the battery plug connector 20 can cooperate with the spare plug port 101 of the battery box 10, so that the battery box 10 can be provided with multiple spare plug ports 101 corresponding to various usage scenarios, thereby improving the applicability of the battery box 10 to different usage environments and different drive vehicle models.

[0058] Specifically, the battery 100 is also provided with a connecting bar connecting the spare plug interface 101 and the battery cell, so as to achieve the purpose of energizing the spare plug interface 101 and the battery cell. The specific structure and type of the connecting bar are not described in detail here.

[0059] In addition, the battery 100 proposed in the embodiment of the present application has all the technical effects of the battery plug connector 20, which will not be elaborated in detail here.

[0060] like Figures 1 to 4 As shown, in some embodiments, the battery 100 includes a battery box 10 , and the battery box 10 includes a front frame plate 11 and a rear frame plate 12 , and both the front frame plate 11 and the rear frame plate 12 are provided with a spare plug interface 101 .

[0061] In this embodiment, by providing spare plug interfaces 101 on the front frame plate 11 and the rear frame plate 12 of the battery box 10, the battery box 10 can be used for both front-wheel drive vehicles and rear-wheel drive vehicles, as well as four-zone vehicles, thereby reducing the number of development variants of the battery box 10, reducing the number of DVP (design verification plan) tests and announcement certifications for the vehicle, reducing the materials of the battery box 10, and reducing the management cost of the battery box 10.

[0062] A third aspect of the present application provides a vehicle, comprising the battery 100 according to the second aspect of the present application.

[0063] In this embodiment, the vehicle proposed in the embodiment of the present application has all the technical effects of the battery 100, which will not be elaborated in detail here.

[0064] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.

[0065] In addition, the embodiments of the present application only describe the structures of the battery connector 20 and the battery 100 that are related to the improvement points of the present application, and do not mean that the battery connector 20 and the battery 100 of the present application do not have other structures. For example, the plug-in body 21 of the battery connector 20 is also provided with structures such as elastic clips. The user can press the elastic clips to make the elastic clips snap onto the spare plug port 101 of the battery box 10, or remove them from the spare plug port 101 of the battery box 10. These structures all belong to the protection scope of the battery connector 20 of the embodiments of the present application, and other structures of the battery connector 20 are not described one by one here.

[0066] The above is only a preferred specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed in the present application should be included in the protection scope of the present application. Therefore, the protection scope of the present application shall be based on the protection scope of the claims.
