FIG1 and FIG2 exemplarily show the state of the mobile battery exchange device disclosed in the present application in use in the side view and the front view. It can be seen from FIG1 and FIG2 that the mobile battery exchange device 10 includes: a battery exchange platform 1 for loading and unloading and carrying batteries; a flatbed truck 2 for transporting batteries; and a lifting mechanism 3, which is configured to lift the motor vehicle to a desired height so that the battery exchange platform can load and unload batteries; wherein the battery exchange platform 1 is placed flat on the flatbed truck 2 and moves with the flatbed truck 2, and the lifting mechanism 3 includes a pair of lifting units 31 arranged at intervals along the transverse direction of the motor vehicle and guides 32 respectively arranged at the bottom of the lifting units, wherein the guides together form a track for the movement of the flatbed truck, and the track guides the movement of the flatbed truck 2 in the longitudinal direction and restricts the movement of the flatbed truck 2 in the transverse direction. The mobile battery exchange device disclosed in the present application is combined with a battery exchange platform, a flatbed truck and a vehicle lifting mechanism to achieve convenient and rapid battery exchange even when the electric vehicle does not have enough power to drive to a battery exchange station. The guide part provided by the lifting mechanism can guide the flatbed truck to move in a desired longitudinal direction while being restricted in the lateral direction, so that the battery exchange platform can accurately install and remove the battery at the battery position at the bottom of the electric vehicle, which ensures the accuracy of the mobile battery exchange device during the battery exchange process.

It should be noted that the longitudinal direction in this application refers to the direction of movement along the electric vehicle or flatbed truck, while the transverse direction refers to the direction transverse to the direction of movement of the electric vehicle or flatbed truck. In other words, the longitudinal and transverse directions in this application refer to the longitudinal and transverse directions of the vehicle coordinate system in the vehicle field.

In some embodiments disclosed in the present application, referring to FIG2 , the lateral spacing between the pair of lifting units 31 can be adjusted. In other words, the two lifting units can be arranged at a desired lateral spacing, so that the lifting mechanism 3 can match electric vehicles of different lateral widths.

In some embodiments disclosed in the present application, as shown in FIG. 1, FIG. 2 or FIG. 3, the flatbed 2 also includes at least one stopper 21, and the lateral position of the stopper 21 is arranged at one longitudinal end of the flatbed 2 corresponding to the lateral position of the guide 32, so that the stopper 21 can be well contacted with the guide. In the case where the lifting mechanism 3 lifts the electric vehicle and the flatbed 2 drives under the bottom of the electric vehicle along the track formed by the guide 32, once the stopper 21 contacts the guide 32, the flatbed 2 is blocked and cannot continue to move (see FIG. 1). The contact between the stopper 21 and the end of the guide 32 can lock the flatbed at the battery replacement position and no longer move, which is beneficial to the stability of the mobile battery replacement device during the battery replacement process. Optionally, the stopper 21 can be constructed as a convex plate protruding downward as shown in FIG. 1.

In some embodiments disclosed in the present application, as shown in FIG2 , the guides 32 together form an inverted trapezoidal track for the movement of the flatbed vehicle 2. The inverted trapezoidal shape of the track formed by the guides 32 can be seen from FIG2 , and this inverted trapezoidal shape can avoid excessive interference between the guides 32 and the wheels of the flatbed vehicle, thereby reducing the friction between the wheels and the guides, thereby avoiding wear on the sides of the wheels.

In some embodiments disclosed in the present application, as shown in FIG. 1 or FIG. 3 , the battery swap platform 1 is connected to the flatbed vehicle 2 by a floating chain or spring 12 and is placed flat on the flatbed vehicle 2. That is, the battery swap platform 1 can be placed flat on the flatbed vehicle with slight movement in three directions relative to the flatbed vehicle 2. This arrangement can improve the lightness and flexibility of the battery transport load and improve the flexibility of battery assembly and disassembly.

In some embodiments disclosed in the present application, as shown in FIG. 1, FIG. 2 or FIG. 3, the flatbed 2 also includes a handlebar 22, which is arranged at the longitudinal end of the flatbed 2 where the stopper 21 is provided, and the relative positions of the handlebar 22 and the stopper 21 can be seen from FIG. 1. The use of the handlebar 22 can make the operation of the flatbed more convenient. In addition, the handlebar 22 is arranged at the end near the stopper 21 for the feasibility of actually operating the handlebar 22, because the stopper 21 is provided, the flatbed 2 can only enter the track from the other end relative to the stopper 21, and if the handlebar 22 is arranged at the other end relative to the stopper 21, it will happen that the handlebar will pass under the bottom of the electric vehicle, which is very inconvenient. Therefore, it is preferred that the handlebar 22 is arranged at the longitudinal end of the flatbed 2 where the stopper 21 is provided.

In some embodiments disclosed in the present application, as shown in FIG. 1 and FIG. 2 , the flatbed trolley 2 further includes a power-assisted wheel 23, which is disposed at the bottom of the flatbed trolley 2 and the longitudinal position of the power-assisted wheel 23 is close to the handlebar 22. Optionally, the power-assisted wheel 23 is configured as an electric drive wheel. This makes it easier to operate the flatbed trolley. In addition, the power-assisted wheel 23 is disposed longitudinally close to the handlebar, which can also make it easier to operate the flatbed trolley.

In some embodiments disclosed in the present application, as shown in Fig. 1, Fig. 2 or Fig. 4, the lifting unit 31 is configured to include a jack. The jack is a mechanism commonly used in vehicle maintenance, and occupies less space than other lifting mechanisms.

In some embodiments disclosed in the present application, as shown in FIG. 1 or FIG. 3 , the battery swap platform 1 includes at least one body positioning element 13, which is arranged near the four sides of the battery swap platform 1. When the battery swap platform 1 contacts the bottom of the electric vehicle, the body positioning element 13 can be locked with the bottom of the electric vehicle to position the battery swap platform 1 at the bottom of the electric vehicle, thereby ensuring the stability of the battery swap process. Optionally, in some embodiments disclosed in the present application, the body positioning element 13 is configured as a body positioning pin that can be raised and lowered. It is feasible that the body positioning pin can be raised and lowered electrically, thereby improving the flexibility of use of the battery swap platform.

In some embodiments disclosed in the present application, referring to FIG. 1 or FIG. 4 , the lifting unit 31 includes a positioning element 33, which is arranged on the lifting surface of the lifting unit 31. The positioning element 33 is positioned at the bottom of the electric vehicle when the lifting unit 31 lifts the electric vehicle, so as to determine the lateral position of the guide portion 32, so that the longitudinal movement of the flat plate 2 can be stably guided thereafter.

In some embodiments disclosed in the present application, referring to FIG. 3 , the battery swap platform 1 further includes at least one battery support element 14 disposed on the battery swap platform 1. The battery support element 14 can support the battery on the battery swap platform 1, thereby avoiding direct surface contact between the battery and the battery swap platform 1, and is beneficial to the heat dissipation of the battery. Preferably, the battery support elements 14 can be evenly distributed on the battery swap platform 1.

Optionally, as can be seen from Figure 4, a battery positioning pin 15 and a battery installation and removal sleeve 16 can also be provided on the battery exchange platform 1, and they can cooperate with each other during the battery exchange process. Specifically, the battery positioning pin 15 can lock the battery exchange platform and the battery, and the battery installation and removal sleeve 16 can tighten or loosen the bolts on the battery, thereby installing or removing the battery.

The present application also discloses a mobile battery exchange device combination. As shown in Figure 5, the mobile battery exchange device combination includes: a lifting mechanism 3, a first flatbed truck 2', a second flatbed truck 2'' and a corresponding first battery exchange platform 1' and a second battery exchange platform 1'', wherein the lifting mechanism 3, two flatbed trucks 2', 2'' and two battery exchange platforms 1', 1'' are constructed as the lifting mechanism 3, flatbed truck 2 and battery exchange platform 1 involved in any one of the embodiments of the present application. The components in the mobile battery exchange device combination can be arranged as follows:

The lifting mechanism 3 lifts the vehicle to a height for battery replacement and the guide 32 forms a track;

The first battery exchange platform 1' moves with the first flatbed vehicle 2' to the bottom of the motor vehicle to remove the depleted battery, and then drives out; and

The second battery exchange platform 1 ″ carries a fully charged battery 20 , and the second battery exchange platform 1 ″ moves with the second flatbed truck 2 ″ to under the motor vehicle to install the fully charged battery 20 to the bottom of the motor vehicle.

The structure of the mobile battery swap device combination can make the battery swap process of electric vehicles faster and more convenient. By having two battery swap platforms and a flatbed truck each perform different processes, the time required for the battery swap process can be greatly saved, which is in line with the requirements of the mobile battery swap scenario for the battery swap process.
