DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0025] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0026] Embodiment:

[0027] Refer to Figures 1 - 5, A vehicle-end docking device, including a mounting plate 1 and a battery terminal connector 6, further including an external connector 5 disposed on the side of the mounting plate 1 away from the vehicle-end connector 2. A wire 7 is connected to the side of the battery terminal connector 6 away from the guiding groove 8. It further includes: a vehicle-end connector 2 disposed on the mounting plate 1. A docking unit is provided on the side of the vehicle-end connector 2 and the battery terminal connector 6 close to each other for power transmission; a locking unit is provided between the vehicle-end connector 2, the battery terminal connector 6 and the docking unit. Wherein, when the docking unit transmits power, the locking unit can move the battery terminal connector 6 towards the vehicle-end connector 2 side.

[0028] Refer to Figures 1 - 3 , The docking unit includes a socket 3 opened on the side of the vehicle-end connector 2 away from the mounting plate 1. A plurality of groups of conductive cores 4 are disposed inside the socket 3. A plurality of groups of mounting holes are also opened on the mounting plate 1 for fixing the mounting plate 1 on the vehicle body. On the one hand, it can ensure the stability of equipment use, and on the other hand, it can facilitate the maintenance by workers. The conductive cores 4 are made of conductive materials.

[0029] Refer to Figure 1 , Figure 2 And Figure 4 , The docking unit further includes a guiding groove 8 opened on the side of the battery terminal connector 6 close to the vehicle-end connector 2. A connector 9 is fixedly connected inside the guiding groove 8. Wherein, the size of the connector 9 matches the size of the socket 3, and the size of the vehicle-end connector 2 matches the size of the guiding groove 8. And, a hole matching the conductive core 4 is opened on the connector 9. It should be noted that there will be a certain frictional force between the vehicle-end connector 2 and the battery terminal connector 6 under the action of the guiding groove 8 and the socket 3, but this frictional force is relatively small to prevent the vehicle-end connector 2 and the battery terminal connector 6 from slipping naturally. In addition, the outer side of the battery terminal connector 6 is made of insulating material, which can isolate the electric energy to improve the safety of the equipment.

[0030] Refer to Figure 2 And Figure 5 , The locking unit includes a plurality of groups of mounting grooves 10 opened on the outer side wall of the connector 9. An electromagnet core 11 is detachably connected inside the mounting groove 10. When there is current passing between the connector 9 and the conductive core 4, the electromagnet core 11 generates magnetism, and the magnetic pole on the side of the electromagnet core 11 away from the connector 9 shows N pole. The specific structure of the electromagnet core 11 can refer to the technical solutions in the prior art. Those skilled in the art can know and will not be elaborated here. It should be noted that the electromagnet core 11 will generate magnetism not only when the current flows in a winding manner, but also when it is in a straight line, but the magnetism generated is smaller compared to the winding type.

[0031] Refer to Figure 5, the locking unit further includes a plurality of sets of movable grooves 12 formed on the outer side wall of the vehicle end joint 2. A locking block 13 is slidably connected inside the movable groove 12. A plurality of sets of springs 14 are fixedly connected between the locking block 13 and the bottom of the movable groove 12. Among them, the movable groove 12 is inclined, and the end close to the outer side wall of the vehicle end joint 2 is inclined towards the mounting plate 1. The outer side wall of the locking block 13 fits with the inner wall of the movable groove 12. The locking block 13 is made of a magnetic material, and the magnetic pole on the side away from the outer side wall of the vehicle end joint 2 shows the N pole. In order to ensure the stable movement of the locking block 13 in the movable groove 12, the spring 14 can be inclined and has the same inclination angle as the movable groove 12. In addition, the number of springs 14 is not limited, and the number of springs 14 can be adjusted according to the actual situation.

[0032] Refer to Figure 5 , it further includes a plurality of sets of lock holes 15 formed on the battery end joint 6 close to one side of the guiding groove 8. When the battery end joint 6 is connected to the vehicle end joint 2, the lock holes 15 and the movable grooves 12 are arranged oppositely, and the inner side wall of the lock holes 15 is perpendicular to the battery end joint 6. In this way, when the locking block 13 moves towards the lock holes 15, a thrust can be generated on the inner wall of the lock holes 15, thereby adjusting the locking force.

[0033] Refer to Figures 1 - 2 , a battery swapping vehicle includes a vehicle body, a battery pack, and the above-mentioned vehicle end docking device. The battery pack and the vehicle end docking device are both arranged on the vehicle body, and the battery pack and the vehicle end docking device are connected by a wire 7.

[0034] In the present utility model, first, the vehicle-end connector 2 is fixed to the vehicle body by means of bolts or the like. Subsequently, the battery-end connector 6 is docked with the vehicle-end connector 2, and the conductive core 4 is inserted into the connector 9. The connector 9 is located within the jack 3, and the vehicle-end connector 2 is located within the guiding groove 8. At this time, the conductive part of the device will not be exposed, thereby improving the safety of the device during use. When the electric vehicle is not being charged, only part of the current of the battery pack flows through devices such as the charging gun at the vehicle end, which is used to maintain various sensing elements and display elements on devices such as the charging gun. At this time, the magnetic force generated by the electromagnet core 11 is relatively small, and the repulsive force generated between it and the locking block 13 can only cause the locking block 13 to just move into the locking hole 15, playing a simple limiting role for the battery-end connector 6. It should be noted that at this time, with a little force, the battery-end connector 6 can also be separated from the vehicle-end connector 2. When the electric vehicle is being charged, the current flowing through the connector 9 and the conductive core 4 is relatively large at this time, causing the electromagnet core 11 to generate a relatively large magnetic force, that is, a relatively large repulsive force is generated between the electromagnet core 11 and the locking block 13, driving the locking block 13 to move towards the locking hole 15. Moreover, when the locking block 13 moves into the locking hole 15, it will push the locking hole 15, making the battery-end connector 6 closer to the vehicle-end connector 2, improving the locking force between them. That is to say, when charging the electric vehicle, even with a large force, it is difficult to separate the vehicle-end connector 2 from the battery-end connector 6, which not only ensures the stability of the electric vehicle charging but also improves the safety of the device during use.

[0035] The above is only the preferred specific implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and the inventive concept of the present utility model, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
