[0061] Now, the example embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0062] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The first aspect of the present application provides a battery replacement device 100, which comprises a walking assembly, a lifting assembly 130 and a battery lifting device 101. The battery lifting device 101 is connected to the walking assembly through the lifting assembly 130.

[0063] The walking assembly comprises a first walking frame 110 and a second walking frame 120. The first walking frame 110 is movable along a first horizontal direction D1. The second walking frame 120 is arranged on the first walking frame 110 and is movable relative to the first walking frame 110 along a second horizontal direction D2, which is perpendicular to the first horizontal direction D1.

[0064] The lifting assembly 130 comprises a drum mechanism 133, a belt 134 and a driving device 135. The drum mechanism 133 is arranged on the second walking frame 120 and vertically above the battery hoist 101. One end of the belt 134 is wound on the drum mechanism 133, and the other end of the belt 134 is connected with the battery hoist 101. The driving device 135 is arranged on the second walking frame 120, and the output end of the driving device 135 is connected with the drum mechanism 133. The driving device 135 is used to drive the drum mechanism 133 to rotate, so that the drum mechanism 133 can be wound or unwound. When the drum mechanism 133 is wound, the belt 134 drives the battery hoist 101 to rise, and when the drum mechanism 133 is unwound, the belt 134 drives the battery hoist 101 to descend.

[0065] According to the battery replacement device 100 of the present application, the combination of the belt 134, the drum mechanism 133 and the walking assembly not only occupies a smaller volume as a whole and reduces the cost, but also can realize the movement of the battery hoist 101 in three directions in space at the same time.

[0066] Specifically, the first walking frame 110 comprises two first cross beams 111 and two first longitudinal beams 112. The two first cross beams 111 are arranged in a spaced manner along the second horizontal direction D2 and extend along the first horizontal direction D1. The two first longitudinal beams 112 are arranged in a spaced manner along the first horizontal direction D1 and extend along the second horizontal direction D2. The first longitudinal beams 112 are connected between the two first cross beams 111.

The first power device 114 is arranged on the connecting beam 115 or the first cross beam 111, and the first power device 114 is connected with the first walking wheels 113 to drive the first walking wheels 113 to walk.

[0069] The second walking frame 120 comprises two second cross beams 121 and two second longitudinal beams 122. The two second cross beams 121 are arranged in the second horizontal direction D2 and extend in the first horizontal direction D1. The two second longitudinal beams 122 are arranged in the first horizontal direction D1 and extend in the second horizontal direction D2, and the second longitudinal beams 122 are connected between the two second cross beams 121. The second walking frame 120 is provided with second walking wheels 123 for walking on the guide rails 116 of the first walking frame 110. As shown in Figure 4 The second walking wheels 123 can be arranged at the two ends of the second cross beams 121. The second cross beams 121 are formed with accommodation spaces 137, and the drum mechanisms 133 are at least partially arranged in the accommodation spaces 137. The rotation axis of the drum mechanism 133 is parallel to the second horizontal direction D2. Optionally, the second walking frame 120 is further provided with a second power device 124 connected with the second walking wheels 123 for driving the second walking wheels 123 to walk. The second power device 124 can also be arranged at the two ends of the second cross beams 121, and is preferably located in the second cross beams 121.

[0070] As an implementation form, the lifting assembly 130 comprises two groups of drum mechanisms 133 arranged on the two sides of the driving device 135 in the second horizontal direction D2. In other words, the two second cross beams 121 are each formed with an accommodation space 137, and the two groups of drum mechanisms 133 are respectively located in the two accommodation spaces 137. Correspondingly, the lifting assembly 130 further comprises a transmission mechanism 136, and the output end of the driving device 135 is connected with the two groups of drum mechanisms 133 through the transmission mechanism 136, so as to realize the synchronous rotation of the two groups of drum mechanisms 133. In this way, the connection points between the belt 134 and the battery lifting appliance 101 at a predetermined distance in the second horizontal direction D2 can be formed.

[0071] As a preferred embodiment, the drum mechanism 133 is wound with two layers of belts 134, and the connection points of the two layers of belts 134 with the battery lifting appliance 101 are at a predetermined distance in the first horizontal direction D1. In this way, the lifting assembly 130 and the battery lifting appliance 101 form four connection points, and a stable force is formed.

[0072] Reference Figure 1 , Figure 3 and Figure 4The upper surface of the battery lifting appliance 101 is fixedly connected with a mounting seat 131, and a pulley 132 is rotatably connected in the mounting seat 131. One end of a belt 134 is wound on a drum mechanism 133, and the other end is wound around the pulley 132 and connected to the bottom of the second walking frame 120. Specifically, the bottom of the second cross beam 121, the two sections of the belt 134 located on both sides of the pulley 132, the mounting seat 131 and the bottom of the second longitudinal beam 122 form an avoiding space to allow the first longitudinal beam 112 to pass through the avoiding space. This structure further increases compactness and saves space.

[0073] As an implementation form, the second walking frame 120 is provided with a steering wheel 125. The steering wheel 125 is arranged on at least one side of the drum mechanism 133 in the first horizontal direction D1, and the steering wheel 125 is spaced apart from the drum mechanism 133 by a predetermined distance. Preferably, a group of drum mechanisms 133 corresponds to two steering wheels 125, and the two steering wheels 125 are located on both sides of the drum mechanism 133 in the first horizontal direction D1, respectively.

[0074] The first layer of the belt 134 extends from the drum mechanism 133 in the first horizontal direction D1, and is wound around the steering wheel 125 to extend downward to pass around the pulley 132 on the battery lifting appliance 101 and is connected to the bottom of the second longitudinal beam 122. The second layer of the belt 134 extends from the drum mechanism 133 in the opposite direction of the first layer of the belt 134, and is wound around the steering wheel 125 to extend downward to pass around the pulley 132 on the battery lifting appliance 101 and is connected to the bottom of the second longitudinal beam 122.
