The battery 11 may be used for power supply of the vehicle 1, for example, the battery 11 may be provided to the chassis of the vehicle 1 as an operation power source of the vehicle 1.

The vehicle 1 may further comprise a controller 12 and a motor 13, the controller 12 being adapted to control the battery 11 to supply power to the motor 13, e.g. for operating power requirements during start-up, navigation and driving of the vehicle 1.

In some embodiments of the present application, the battery 11 may not only serve as an operating power source for the vehicle 1, but also as a driving power source for the vehicle 1, providing driving power for the vehicle 1 instead of or in part instead of fuel oil or natural gas.

Referring to fig. 2, the power exchange station may include a lifting functional module 2, a mobile power exchange device, and a battery storage system, and the vehicle 1 may be capable of moving to a power exchange platform and performing battery 11 exchange on the lifting functional module.

Specifically, referring to fig. 3, the lifting function module 2 includes a lifting device 21, and after the vehicle moves to the lifting function module 2 and completes positioning, the lifting device 21 is triggered to lift the vehicle. When the vehicle is lifted, the mobile battery replacing device can move to the lower part of the vehicle to take out the battery to be charged in the vehicle and drive the battery to move to the battery storage system for charging treatment, meanwhile, the fully charged battery in the battery storage system is placed in the mobile battery replacing device, and the battery is transported to the vehicle through the mobile battery replacing device, so that the replacement of the battery is realized. The lifting device 21 then drives the vehicle down to the initial position so that the vehicle can exit the lifting function.

The embodiment provides a lifting device 21 for lifting a vehicle, wherein the lifting device 21 comprises a driving mechanism 3, a lifting arm 4, a supporting plate 5 and a supporting block 6. The lifting arm 4 is connected with the driving mechanism 3 so as to drive the lifting arm 4 to lift the vehicle through the driving mechanism 3, and the supporting plate 5 is connected with the lifting arm 4 so as to lift together with the lifting arm 4; the supporting block 6 is connected to the lifting arm 4, and the supporting block 6 is used for protruding out of the supporting plate 5 when the lifting arm 4 lifts to support the vehicle.

The driving mechanism 3 is used for providing driving force for the lifting arm 4 so that the lifting arm 4 drives the vehicle to lift together. The support plate 5 is located on one side of the lifting arm 4 and is lifted together with the lifting arm 4 during lifting, and the support plate 5 can function as a support for the vehicle instead of the lifting arm 4 when entering or leaving the lifting device 21.

The supporting block 6 is arranged on the lifting arm 4, and the supporting block 6 can be fixed with the lifting arm 4 into a whole in a welding mode or the like, and can also be fixed by adopting detachable connection. During lifting, the supporting blocks 6 are configured to protrude from the supporting plate 5, i.e. the chassis of the vehicle does not contact with the supporting plate 5, and the lifting arms 4 lift the vehicle through the supporting blocks 6, so that the contact area with the chassis can be reduced.

It should be noted that, since the supporting block 6 needs to protrude from the supporting plate 5 during the lifting process, the positional relationship between the two needs to avoid interference. Illustratively, the support plate 5 has a relief hole penetrating in the lifting direction, the relief hole corresponding to the position of the support block 6, through which the support block 6 can pass during lifting so as to protrude from the support plate 5.

The supporting shoe 6 in this application embodiment can be relative backup pad 5 outstanding setting to in lifting process, supporting shoe 6 can replace backup pad 5 and vehicle chassis contact, reduces the area of contact on the chassis, reduces the wearing and tearing of lifting in-process to the chassis and destroy.

In some embodiments, as shown in fig. 3, the lifting arm 4 is intended to penetrate into the underside of the vehicle, and the support plate 5 and the support block 6 are provided on the surface of the lifting arm 4 facing the vehicle.

The lifting arm 4 extends deep into the underside of the vehicle, i.e. the lifting arm 4 can be located on one side of the vehicle chassis, the support plate 5 and the support block 6 are both arranged on the side of the lifting arm 4 facing the vehicle chassis, the support plate 5 supports the vehicle when the vehicle is driven into or out of the lifting device 21, and the support block 6 is in direct contact with the vehicle during lifting. Optionally, a groove is formed in the vehicle chassis, the size and shape of the groove are matched with those of the supporting block 6, when the vehicle is lifted, the supporting block 6 can penetrate into the groove to limit the vehicle, the vehicle and the supporting block 6 are kept stationary in the lifting process, and the lifting reliability is improved. The embodiment of the present application is not limited in terms of the size and shape of the support block 6.

In this application embodiment, supporting shoe 6 plays the supporting role to the vehicle respectively at different moments with backup pad 5, ensures to trade the quick progress of electric process and vehicle removal process, reduces the wearing and tearing destruction to the vehicle chassis simultaneously.

In some embodiments, referring to fig. 4, the support block 6 is further configured to be flush with the support plate 5 when the lifting arm 4 is lowered to the first predetermined height.

The first predetermined height may be the height of the lifting arm 4 when the vehicle can exit the lifting device 21, and at this time, the supporting plate 5 can replace the lifting arm 4 to play a role in supporting the vehicle when the vehicle exits the lifting device 21, and at the same time, the supporting plate 5 can also hide the lifting arm 4 when the lifting device 21 does not work, so as to play a role in protecting the lifting arm 4.

In addition, the embodiment of the application also allows the support blocks 6 to be flush with the support plate 5 when the lifting arm 4 is lowered to the first predetermined height. Wherein, being flush with the support plate 5 means that the surface of the support block 6 facing the vehicle side is on the same plane as the surface of the support plate 5 facing the vehicle side. The design can enable the supporting plate 5 and the supporting block 6 to form a flat supporting surface together, avoid the blocking of the supporting block 6 protruding out of the supporting plate 5 in the vehicle advancing process, and improve the fluency of the vehicle driving in and driving out.

In some embodiments, referring to fig. 3 and 5, the lifting device 21 further includes a floating mechanism 7, where the floating mechanism 7 is used to support and drive the support plate 5 to disengage from the lifting arm 4 after the lifting arm 4 is lowered to the second predetermined height, so that the support plate 5 can be flush with the support block 6; and at least part of the floating mechanism 7 gradually moves away from the support plate 5 when the lifting device 21 lifts, so that the lifting arm 4 drives the support plate 5 to lift together.

When the lifting arm 4 is lowered to the second predetermined height, the support plate 5 needs to be moved relative to the lifting arm 4 so that the support plate 5 can be flush with the support block 6, thereby ensuring smooth movement of the vehicle. To achieve this effect, the present application adds a floating mechanism 7, where the floating mechanism 7 replaces the lifting arm 4 to support the support plate 5 when the lifting arm 4 descends to the second predetermined height, so that the support plate 5 does not descend along with the lifting arm 4, and the support plate 5 and the lifting arm 4 relatively move, so as to achieve the flush of the support block 6 and the support plate 5.

It is understood that the first predetermined height is different from the second predetermined height, and the second predetermined height is higher than the first predetermined height. In the descending process, the lifting arm 4 is firstly descended to a second preset height, at this time, the floating mechanism 7 replaces the lifting arm 4 to support the supporting plate 5, so that the supporting plate 5 does not move along with the lifting arm 4 any more, then the lifting arm 4 is further descended compared with the supporting plate 5 until the lifting arm is descended to the first preset height, at this time, the supporting block 6 is in a level state with the supporting plate 5, the lifting arm 4 does not move along with the supporting block, and the descending process is finished.

In addition, during lifting, the support plate 5 is not lifted synchronously with the lifting arm 4 until the lifting arm 4 reaches the second predetermined height. Specifically, during the lifting arm 4 is lifted from the first predetermined height to the second predetermined height, the support plate 5 is still supported by the floating mechanism 7 and remains stationary, and the lifting arm 4 moves relatively to the support plate 5, and the support block 6 gradually protrudes from the support plate 5. When the lifting arm 4 reaches the second preset height, the floating mechanism 7 no longer supports the supporting plate 5, and the lifting arm 4 drives the supporting plate 5 to lift synchronously.

In some embodiments, as shown in fig. 3 and 5, the floating mechanism 7 includes a first portion 71 provided to the lifting arm 4 and a second portion 72 provided to the ground, the second portion 72 being configured to lift the first portion 71 when the lifting arm 4 is lowered to a second predetermined height so that the support plate 5 is flush with the support block 6 by the first portion 71.

The floating mechanism 7 comprises a first part 71 and a second part 72, the first part 71 is arranged on the lifting arm 4, the second part 72 is arranged on the ground, and the first part 71 is connected with the supporting plate 5 and can be lifted together with the lifting arm 4; the second portion 72 may be fixed to the ground and remain stationary throughout. Wherein the first part 71 can be fastened to the support plate 5 by means of a screw connection or the like, so that the first part 71 always moves synchronously with the support plate 5.

The first part 71 may be slidably connected to the lifting arm 4 in the lifting direction such that when the lifting arm 4 is lowered to a second predetermined height, the second part 72 abuts and supports the first part 71, after which the lifting arm 4 continues to be lowered, whereas the first part 71, due to the support of the second part 72, stops moving with the support plate 5, and the lifting arm 4 continues to move until the support plate 5 is level with the support block 6. In the lifting process, when the lifting arm 4 exceeds the second preset height, the second part 72 is not abutted against the first part 71, and the first part 71 and the supporting plate 5 are lifted by the lifting arm 4.

The floating mechanism 7 in this embodiment of the present application comprises two parts, and the second part 72 can replace the lifting arm 4 to support the first part 71 and the supporting plate 5 after the lifting arm 4 descends to the second predetermined height, so that the supporting plate 5 and the supporting block 6 relatively move, and the supporting plate 5 and the supporting block 6 are flush.

In some embodiments, referring to fig. 3 and 6 to 8, the lifting arm 4 is provided with a through hole 41, the first portion 71 includes a first slider 711, a second slider 712, and a connection block 713, the first slider 711 is provided on a surface of the lifting arm 4 facing the support plate 5, the second slider 712 is provided on a surface of the lifting arm 4 facing away from the support plate 5, and the connection block 713 connects the first slider 711 and the second slider 712; wherein the connection block 713 is slidably connected to the through hole 41 in the axial direction of the through hole 41.

The first slider 711 and the second slider 712 are provided on both sides of the connection block 713 in the lifting direction, the first slider 711 being located on a side near the support plate 5, the second slider 712 being located on a side near the second portion 72, the first portion 71 being slidably connected to the lifting arm 4 through the connection block 713. Specifically, the through hole 41 is disposed through the lifting arm 4, the axial direction of the through hole 41 is the lifting direction of the lifting arm 4, and the length of the connection block 713 in the lifting direction is greater than the axial length of the through hole 41, so that the connection block 713 can slide relatively in the through hole 41, that is, the first portion 71 can slide relatively to the lifting arm 4.

The first slider 711 and the second slider 712 are located on both sides of the through hole 41, respectively, and the first slider 711 and the second slider 712 need to be larger than the through hole 41, that is, the first slider 711 and the second slider 712 cannot pass through the through hole 41. This design allows to limit the maximum distance of movement between the first portion 71 and the lifting arm 4 while satisfying the sliding connection between them, avoiding the separation of the two in the lifting direction.

When the lifting arm 4 is lowered to the second predetermined height, the second portion 72 abuts against the second slider 712, and provides a supporting force to the first portion 71 via the second slider 712, and the supporting plate 5 and the first portion 71 are not moved any more, at this time, the lifting arm 4 can be further lowered until the supporting block 6 is flush with the supporting plate 5. After the lifting arm 4 is lifted to the second predetermined height, the lifting arm 4 drives the first slider 711 to separate the first portion 71 from the second portion 72, and simultaneously drives the support plate 5 to lift synchronously.
