[0042] The present invention is further described below by way of embodiments in conjunction with the accompanying drawings, but the present invention is not limited to the scope of the embodiments.

[0043] Figure 1-2 An example of a battery swapping device 100 is illustrated according to an embodiment of the present invention.

[0044] The battery exchange device 100 includes a traveling mechanism 120 and a battery exchange platform 110. The battery exchange platform 110 is disposed on the traveling mechanism 120 and can be raised and lowered relative to the traveling mechanism 120. The battery exchange platform 110 is used to install and remove and carry the battery pack of the vehicle.

[0045] like Figure 3-4 As shown, the walking mechanism 120 includes: a body 121 and a driving wheel 122 and a driving mechanism disposed on the body 121; the driving mechanism is used to drive the driving wheel 122 to rotate.

[0046] The rotation of the driving wheel 122 drives the walking mechanism 120 to move.

[0047] At least one driving wheel 122 and at least one supporting wheel 124 are respectively disposed on two sides of the body 121 .

[0048] The driving wheel 122 is used to drive the traveling mechanism 120 to move, and the supporting wheel 124 is used to support the traveling mechanism 120. Since the traveling mechanism 120 needs to carry the battery exchange platform 110 to move, it itself needs to bear pressure, and the supporting wheel 124 is used to share the pressure of the driving wheel 122. The supporting wheel 124 is generally unpowered or not directly driven by a power source.

[0049] Optionally, the driving wheel 122 and the supporting wheel 124 are connected via a synchronous belt or a chain, and the driving wheel 122 drives the supporting wheel 124 to rotate.

[0050] The driving wheel 122 is a rubber wheel or a metal wheel, and / or the supporting wheel 124 is a rubber wheel or a metal wheel.

[0051] Preferably, the driving wheel 122 is a rubber wheel, and the supporting wheel 124 is a metal wheel. The friction between the rubber wheel and the track is large, and the driving wheel 122 can drive the walking mechanism 120 to move well by using a rubber wheel, while the supporting wheel 124 is used for bearing pressure, and its strength requirement is high, so it is suitable to use a metal wheel.

[0052] The rubber wheel is a wheel with rubber coating on the peripheral surface. Of course, optionally, the rubber wheel can also be made of rubber purely.

[0053] The main body 121 is provided with driving wheels 122 on opposite sides of the head end or the tail end in the traveling direction of the traveling mechanism 120. Generally, the driving wheels 122 are provided in pairs, and are provided on both sides for the convenience of balance.

[0054] The driving mechanism is disposed at the head end or the tail end of the body 121 in the traveling direction of the traveling mechanism 120 .

[0055] The driving mechanism includes a motor 123 and a driving shaft 129 . The driving shaft 129 is connected to the driving wheel 122 . The motor 123 drives the driving shaft 129 to rotate so as to drive the driving wheel 122 to rotate.

[0056] The motor 123 and the drive shaft 129 are arranged on the drive mounting part 127 of the main body 121. A mounting plate 128 is arranged at the center of the drive mounting part 127. The drive shaft 129 is rotatably passed through the mounting plate 128. The motor 123 is fixed on the mounting plate 128. The two ends of the drive shaft 129 are respectively connected to the drive wheel 122.

[0057] The motor 123 and the drive shaft 129 are meshed and connected to each other via a gear 130 .

[0058] Figure 4 One arrangement of the drive mounting portion 127 is shown. However, the present invention is not limited thereto.

[0059] Figure 5 Another embodiment according to the present invention illustrates another arrangement of the drive mounting portion 127 .

[0060] like Figure 5 As shown, the motor 123 is fixed to one end of the drive mounting portion 127, and the drive shaft 129 is respectively connected to both ends of the drive mounting portion 127 and connected to the drive wheel 122. The motor 123 and the drive shaft 129 are meshed and connected to each other through a gear 130.

[0061] The motor 123 is fixed to one end of the drive installation portion 127 , so that the center position of the drive installation portion 127 can be vacated to place other electronic devices.

[0062] The support wheel 124 includes a groove wheel 125 and a smooth wheel 126. The groove wheel 125 is located on one side of the traveling mechanism 120 in the traveling direction, and the smooth wheel 126 is located on the other side of the traveling mechanism 120 in the traveling direction. The groove wheel 125 can play a guiding role, so that the traveling mechanism 120 moves linearly along the track.
