Slidably hinged such that the hinge point is slidable, in this embodiment horizontally slidable. Fixedly hinged is fixed at a hinge point and is not movable.

The first support arm 13 and the second support arm 14 are not hinged or connected to each other. The lift driving unit 15 is telescopic to rotate the first support arm 13, thereby lifting and lowering the fixed tray 22.

The lifting drive unit 15 is preferably a hydraulic drive device.

Alternatively, the lifting mechanism 12 may also adopt a mechanical structure capable of lifting, such as a screw-nut transmission structure or a direct hydraulic lifting structure.

The mounting platform 16 includes: tray 17 and fixed tray 22.

The tray 17 is for carrying the batteries. Both the battery pack for power shortage detached from the electric vehicle lamp and the battery pack for power full to be attached to the electric vehicle are placed on the tray 17 for transportation and installation.

The tray 17 is provided on the fixed tray 22 and is horizontally movable in a first direction with respect to the fixed tray 22.

The fixed tray 22 and the tray 17 can be connected through a linear motor, a screw nut transmission mechanism and other driving devices, so that the tray 17 moves relative to the fixed tray 22.

The fixed plate 22 is provided with first guide forks 23 on both sides, and the first guide forks 23 are horizontally movable in a second direction perpendicular to the first direction.

The fixed disk 22 is provided with first guide rails 25 extending from both sides, and the first guide fork 23 is slidably disposed on the first guide rails 25.

The fixed disk 22 is provided with a first driving member for driving the first guide fork 23 to slide on the first guide rail 25.

The first driving piece is any one of belt wheel driving, screw nut driving and linear motor.

The first guide fork 23 is used for being clamped with a lock base on a quick-change bracket of the vehicle.

By the movement of the two first guide forks 23 in the second direction, the distance between the two first guide forks 23 is adjusted so as to fit the size of the battery pack loaded on the mounting platform 16.

Two sides of the tray 17 (in this embodiment, side areas of the upper surface of the tray 17, or in other embodiments, side surfaces of the tray 17) are provided with second guide forks 24, and the second guide forks 24 are horizontally movable in the second direction.

The upper surface of the tray 17 is provided with a second guide rail 26, and the second guide fork 24 is slidably disposed on the second guide rail 26.

The tray 17 is provided with a second driving member for driving the second guide fork 24 to slide on the second guide rail 26.

The second driving piece is any one of belt wheel driving, screw nut driving and linear motor.

The second guide fork 24 is used for being clamped with a positioning block on the battery pack.

By the movement of the two second guide forks 24 in the second direction, the distance between the two second guide forks 24 is adjusted so as to fit the size of the battery pack loaded on the mounting platform 16.

The tray 17 has a mounting layer 18 and a connection layer 21. The connection layer 21 is provided on the fixed plate 22 and is horizontally movable with respect to the fixed plate 22, and the mounting layer 18 is detachably provided above the connection layer 21.

The second guide rail 26 is disposed on the upper surface of the connection layer 21. As shown in fig. 4, the mounting layer 18 is provided with a through hole 181, and the through hole 181 allows the second guide fork 24 to pass through and slide along the second guide rail 26 over the entire length of the second guide rail 26 inside the through hole 181.

The connection layer 21 is further provided with an insertion groove 211, and the insertion groove 211 cooperates with an insert on the lower surface of the carrying layer 18 to limit the relative movement of the carrying layer 18 and the connection layer 21 in the first direction. Assembling the mounting layer 18 and the connection layer 21 in this way facilitates the disassembly of the mounting layer 18 and the connection layer 21.

The elastic piece is arranged between the carrying layer 18 and the connecting layer 21, can play a role in buffering the carrying layer 18, can be used for placing the damage to the battery pack placed on the carrying layer 18, can also adjust the positioning error in the vertical direction, and is convenient for positioning the battery pack during installation and disassembly. The resilient member is preferably a spring 20.

Alternatively, the mounting layer 18 and the connection layer 21 may be fixedly connected, i.e., not detachable. The second rail 26 may be directly laid on the upper surface of the mounting layer 18.

In order to increase the fit of the mounting platform 16, it is optional to lengthen the length in the second direction of the portion where the second rail 26 is provided, to facilitate laying longer second rails 26 or to lay the second rails 26 closer to both sides, in order to increase the adjustable range of the distance between the second guide forks 24 so that it can fit a wider variety of batteries.

Alternatively, it is also possible to provide the first guide fork on only one side of the holding pan, with the first guide rail protruding on only one side of the holding pan and the fixed guide fork on the other side of the holding pan in cooperation. By moving the first guide fork on one side in the second direction, the distance between the first guide fork and the fixed guide fork is adjusted so as to adapt to the size of the battery pack loaded on the mounting platform.

Alternatively, it is also possible to provide the second guide fork on only one side of the pallet, in conjunction with which the second guide rail is provided on only one side of the pallet and the fixed guide fork is provided on the other side of the pallet. By moving the second guide fork on one side in the second direction, the distance between the second guide fork and the fixed guide fork is adjusted so as to adapt to the size of the battery pack loaded on the mounting platform.

As is well known, the length and width dimensions of battery packs of different types are different, and electric vehicles of different types may be equipped with battery packs of different types, which would greatly increase the cost of the power exchange station if different power exchange devices are equipped for each type, while the mounting platform and the power exchange device comprising the same can be adapted to vehicle battery packs of various types by arranging a first guide fork and a second guide fork which can move in a second direction, thereby realizing universality of the power exchange station.

The present embodiment illustrates the battery exchange apparatus 10 including the mounting platform 16, but the mounting platform 16 is not limited thereto, and the mounting platform 16 may be applied to other apparatuses for battery pack replacement or transportation than the battery exchange apparatus 10 illustrated in the present embodiment, so as to achieve universality of the battery exchange station.

Fig. 5 illustrates a control method for controlling the mounting platform 16 as described above, according to an embodiment of the present invention.

The control method comprises the following steps:

Step 100: the model of the vehicle is detected.

The detection may be a manual detection, i.e. the identification of the vehicle model by the human eye.

It is also possible to make the machine automatic identification, for example by providing a monitoring device at the vehicle inlet of the station where the mounting platform 16 is used, for identifying the vehicle model. Such a vehicle model identification technique is widely used in the prior art and will not be described here.

Step 200: the moving positions of the first guide fork 23 and the second guide fork 24 are controlled according to the detection result.

The different vehicle models correspond to battery packs with different sizes, the sizes of the corresponding battery packs are searched according to the detected models, then the first guide fork 23 and the second guide fork 24 are adjusted to preset positions, so that the distance between the two first guide forks 23 is matched with the distance between corresponding vehicle locking bases, and meanwhile, the distance between the two second guide forks 24 is matched with the width of the battery pack, and therefore the four guide forks on the mounting platform 16 can be accurately matched with the battery packs, and accordingly the battery packs can be mounted and dismounted smoothly.

If manual detection is performed in step 100, the movement of the first and second guide forks 23 and 24 is manually controlled by a human.

If the machine is used for automatic recognition in step 100, the data of the monitoring device is correspondingly received by a control unit, and then an instruction is sent to the first driving piece by the control unit, so that the moving positions of the first guide fork 23 and the second guide fork 24 are automatically adjusted. The control unit may be a control device of the power exchange station using the mounting platform 16, or may be a device provided separately on the mounting platform 16 and having signal transmission and program processing functions.
