DETAILED DESCRIPTION

[0041] The utility model is further explained by the following examples, but the utility model is not limited in the scope of the examples.

[0042] As Figures 1 to 7 shown, the utility model provides a battery transfer device 1, the battery transfer device 1 includes car 200 and frame 100, car 200 is arranged in frame 100 and can move up and down along frame 100, frame 100 includes a plurality of stand columns 110 spaced apart along the circumferential direction, and the stand column 110 includes reinforcing piece 1101 and stand column body 1102, the stand column body 1102 is made of channel steel and has two side walls oppositely arranged, and the reinforcing piece 1101 is connected to the side wall away from car 200 in the two side walls and extends from the first end to the second end of the stand column body 1102 along the height direction.

[0043] In the embodiment, the reinforcing piece 1101 can increase the strength of the stand column body 1102 to ensure the overall strength and reliability of the battery transfer device 1, even if the stand column 110 and the battery rack are independently arranged, the stand column 110 can also maintain sufficient strength, thereby facilitating the normal operation of the battery transfer device 1. In addition, the reinforcing piece 1101 is connected to the side wall away from car 200, and the reinforcing piece 1101 is arranged away from the working area of car 200, which does not affect the normal operation of car 200, thereby further ensuring the normal operation of the battery transfer device 1.

[0044] It should be noted that the car 200 is a structure known in the prior art, which is well known to those skilled in the art, and will not be described here.

[0045] As Figures 1-3As shown, the outer edge of the reinforcing member 1101 towards the side of the side wall is aligned with the outer edge of the side wall (corresponding to the X direction described below, i.e. the direction in which the battery 200 is taken out or placed), so that the side of the reinforcing member 1101 towards the side wall is adapted to the side wall.

[0046] In this way, the outer edge of the reinforcing member 1101 is aligned with the side wall of the column body 1102, and the reinforcing member 1101 covers a larger area relative to the side wall of the column body 1102, which is conducive to enhancing the reinforcing effect. In combination with the above-mentioned extension of the reinforcing member 1101 from the first end to the second end of the column body 1102 in the height direction, the reinforcing member 1101 can reinforce the column body 1102 in the height direction of the column body 1102 (the height direction is perpendicular to the X direction and also perpendicular to the Y direction described below), and at the same time, the reinforcing member 1101 can also reinforce the column body 1102 in the X direction, thereby further enhancing the reinforcing effect on the column body 1102.

[0047] Further, as a preferred arrangement, in the present embodiment, the reinforcing member 1101 is made of a square tube. Alternatively or additionally, the reinforcing member 1101 is connected to the column body 1102 by welding.

[0048] In this way, the reinforcing member 1101 is made of a square tube, which achieves the lightest weight possible while ensuring the reinforcing effect, and is easy to obtain. In addition, the reinforcing member 1101 and the column body 1102 are connected by welding, which is a simple and reliable connection method, and is conducive to reducing the overall manufacturing cost of the battery transfer device 1.

[0049] It should be noted that in other alternative embodiments, the reinforcing member 1101 can also be provided in other structural forms, such as a solid plate structure, a block structure, etc., and the specific form is not limited.

[0050] As shown in FIGS. Figure 1 , Figure 2 and Figure 6 The battery transfer device 1 also includes a base and a top plate. The base is connected to the bottom of the frame 100, and the base is composed of a plurality of support blocks arranged at intervals, and the plurality of support blocks are arranged one by one at the bottom of the plurality of columns 110. The top plate is connected to the top of the frame 100, and the top plate is composed of a plurality of top units arranged at intervals, and the plurality of top units are arranged one by one at the top of the plurality of columns 110. The battery transfer device 1 can be connected to an external structure through the top plate and the base, such as the battery transfer device 1 can be connected by fitting the top plate to the top surface of the container of the battery swap station, and the battery transfer device 1 can be connected by fitting the base to the bottom surface of the container of the battery swap station.

[0051] In the embodiment, the top plate and the base are both provided as a plurality of spaced-apart sub-structures (the top plate comprises a plurality of top units, and the base comprises a plurality of support blocks), which is advantageous in reducing the overall weight, saving materials and costs, and reducing the machining precision, and is convenient for machining and manufacturing. In addition, the base and / or the top plate can be better fitted to the external structure (such as the bottom surface and / or the top surface of the container as described above), and the connection is more stable and less likely to be warped, which is advantageous in further ensuring the normal operation of the battery transfer device 1. Specifically, when the top plate and / or the base are a whole plate, it is easy to cause instability and warping in some places, and if a certain flatness is to be met, the corresponding machining precision requirement will be relatively high. Meanwhile, taking the base as an example, a whole base is connected to the bottom surface of the container and a plurality of columns 110 at the same time, and therefore a high precision is required during connection and installation.

[0052] At least with reference to Figures 1-3 It should be understood that one side wall for connecting with the reinforcing member 1101 is a first side wall, and the other side wall is a second side wall. A plurality of detection marks 140 are arranged on the second side wall in the height direction of the column body 1102, and the plurality of detection marks 140 are arranged one-to-one corresponding to a plurality of battery storage positions on the battery rack.

In this way, the detection block 1401 can be directly connected to the second side wall without the need for punching the second side wall, which is advantageous in ensuring the strength of the column 110 and protecting the column 110. In addition, the arrangement of the detection block 1401 is advantageous in increasing the detection area and further improving the detection precision.

[0055] As a preferred arrangement, the detection block 1401 is fitted to the second side wall and is welded to the second side wall.

[0056] The detection block 1401 is convenient and reliable to install with the column 110, and does not damage the structure of the second side wall, which is advantageous in ensuring the overall strength of the column 110.

[0057] It should be noted that the specific shape of the detection block 1401 and the mounting manner thereof with the second side wall are not specifically limited, and any structure and mounting manner applicable to this can be adopted, as long as the normal detection can be realized without affecting the strength of the column 110 and the normal operation of the battery transfer device 1.

[0058] In addition, the specific number of the detection block 1401 is not limited, as long as it can be adapted to the number of the battery positions to meet the detection requirements.

In addition, the length of the identification body 1402 protruding from the second side wall can be controlled within a predetermined range, which can avoid affecting the wiring on the column 110, thereby further ensuring the normal operation of the battery transfer device 1.

[0061] It should be noted that the structure of the identification body 1402 is provided as a bolt, which is only an example. In fact, it can be set according to different detection requirements, as long as the normal detection target can be achieved.
