The third direction is the length direction of the side beam 2. The fourth direction is perpendicular to the third direction and consistent with the second direction. After the inserting portion 72 is inserted into the first hole portion 61 along the third direction, the clamping portion 71 is clamped in the second hole portion 62. The inserting portion 72 is first inserted into the first hole portion 61, and the clamping portion 71 is aligned with the second hole portion 62. Then the clamping portion 71 moves toward the second hole portion 62, so that the clamping portion 71 enters the second hole portion 62, and the cross beam 1 and the side beam 2 are clamped and fixed. The second plate 12 and the side beam 2 are engaged and positioned by using the first hole portion 61, which is larger than the second hole portion 62, and the second hole portion 62 is smaller than the first hole portion 61. Preferably, the first direction is the extension direction of the cross beam 1, and the second direction is the direction perpendicular to the cross beam 1. Specifically, the side beam 2 can be partially inserted into the larger first hole portion 61 first, and then engaged into the smaller second hole portion 62, so as to achieve reliable positioning between the side beam 2 and the cross beam 1.

[0147] In this embodiment, the side of the connecting piece 7 has a groove, the portion where the groove is located constitutes the engaging portion 71 of the connecting piece 7, and the portion of the connecting piece 7 away from the second plate 12 relative to the engaging portion 71 constitutes the inserting portion 72.

[0148] like Figure 2 and Figure 3 As shown, the end of the first plate 11 of the crossbeam 1 has a second joint portion that is matched and connected with the external base 3, and the second joint portion includes a first fixing groove 14 for partially inserting the base 3. In addition, the third plate 21 has a fourth joint portion that is matched and connected with the external base 3, and the fourth joint portion includes a second fixing groove 24 for partially inserting the base 3.

[0149] The cross beam 1 and the base 3, as well as the side beam 2 and the base 3, are positioned in the form of protrusions and grooves, which have a simple structure and are convenient to position, and can be fixed by riveting, welding, bonding, etc. The side beam 2 and the cross beam 1 are connected together with the assistance of the base 3, which improves the connection reliability between the side beam 2 and the cross beam 1. Furthermore, the bottoms of the first fixing groove 14 and the second fixing groove 24 are both provided with mounting holes 25, and the first positioning portion 31 and the second positioning portion 32 are both provided with threaded holes 33 corresponding to the mounting holes 25, so that the cross beam 1 and the side beam 2 can be fixed to the base 3 by threaded connection.

[0150] The first plate 11 of the cross beam 1 has a first recessed portion that is recessed toward the inside of the cross beam 1, and the first recessed portion constitutes a first fixing groove 14. A first fixing portion fixed to the base 3 is provided on the first plate 11 in the first recessed portion or on both sides thereof. Similarly, the third plate 21 of the side beam 2 has a second recessed portion that is recessed toward the inside of the side beam 2, and the second recessed portion constitutes a second fixing groove 24. A second fixing portion fixed to the base 3 is provided on the third plate 21 in the second recessed portion or on both sides thereof. Both the cross beam 1 and the side beam 2 can be profiles, and a groove extending along the length direction of the cross beam 1 is integrally formed on the profile by aluminum extrusion. The groove can play a role in strengthening the cross beam 1, and a part of the groove constitutes the first recessed portion or the second recessed portion. More preferably, the cross beam 1 and the side beam 2 have the same cross section, that is, the cross beam 1 and the side beam 2 are different beams made of the same type of profile, which reduces the material preparation cost.

[0151] In other embodiments, the first recessed portion may also be a groove directly cut or stamped on the first plate 11 .

[0152] The first joint portion of the cross beam 1 further includes a third positioning groove 16 located on the second plate 12, and the fourth joint portion of the side beam 2 further includes a positioning piece 8 extending outward from the end of the third plate 21, the position of the positioning piece 8 corresponds to the position of the third positioning groove 16, and the positioning piece 8 can be inserted into the third positioning groove 16.

[0154] The second plate 12 is provided with a plurality of first bending portions 13 arranged at intervals, the first bending portions 13 are recessed toward the inside of the cross beam 1, and the connecting holes 6 are provided at the bottom of the recess. The connecting holes 6 are provided in the first bending portions 13, so that the side beam 2 can be better fitted after being inserted into the cross beam 1, and the inner wall of the first bending portion 13 can limit the side beam 2, further improving the reliability of the connection between the cross beam 1 and the side beam 2.

[0155] In this embodiment, the fourth plate 22 is provided with a plurality of second bending portions 23 arranged at intervals, the second bending portions 23 are recessed toward the inside of the side beam 2, and the connecting piece 7 is provided at the bottom of the recess. If the connecting piece 7 is connected to the outer portion of the fourth plate 22, the connecting piece 7 is easily bent during transportation, and when the side beam 2 is connected to the cross beam 1, since the connecting piece 7 needs to be translated toward the second hole portion 62, the end of the cross beam 1 will protrude from the outer wall of the side beam 2, and the assembly aesthetics will be affected.

[0156] The second plate 12 is provided with a curling portion 15 at the end away from the first plate 11, and the curling portion 15 is bent toward the inside of the cross beam 1. The fourth plate 22 is provided with a curling portion 15 at the end away from the third plate 21, and the curling portion 15 is bent toward the inside of the side beam 2.

[0157] The depression of the second bent portion 23 is also provided with a connection gasket 5 that can slide in the depression along the third direction (i.e., the length direction of the side beam 2), and the connection gasket 5 is configured to slide to the outer edge of the plug hole. After the engaging portion 71 of the connection piece 7 enters the second hole portion 62, the connection gasket 5 can be inserted into the first hole portion 61, so the connection gasket 5 can prevent the connection piece 7 of the side beam 2 from sliding out after it is withdrawn from the second hole portion 62 of the cross beam 1 to the first hole portion 61, thereby improving the connection reliability between the cross beam 1 and the side beam 2. The connection gasket 5 can be an independent part, or a part attached to the side beam 2.

[0158] As a preferred embodiment, the frame assembly further includes a sleeve 4 connected to the cross beam 1, and the sleeve 4 is disposed between two second plates 12 at the connection between the cross beam 1 and the side beam 2. The sleeve 4 can be used to connect the vertical columns to achieve the splicing of the three-dimensional frame.

[0159] like Figure 2 As shown, the sleeve 4 has a reserved hole 41, which is arranged along the fifth direction. The reserved hole 41 includes a third hole portion 42 and a fourth hole portion 43 that are connected. The width of the third hole portion 42 in the sixth direction is greater than the width of the fourth hole portion 43 in the sixth direction. The fifth direction is consistent with or perpendicular to the sixth direction. The position and size of the reserved hole 41 correspond to the socket 6 of the crossbeam 1. The connecting piece 7 of the side beam 2 can be inserted into the reserved hole 41 after passing through the socket 6, so that the sleeve 4 is fixed to the side beam 2, wherein the third hole portion 42 of the reserved hole 41 corresponds to the first hole portion 61 of the contact hole, and the fourth hole portion 43 corresponds to the second hole portion 62. The frame assembly also includes a column, and the bottom of the column is sleeved outside the sleeve 4 or inside the sleeve 4. Adding the connection of the vertical column makes the scope of use wider. The frame assembly can connect profiles extending in three different directions together. In some embodiments, the upright column may be directly inserted between the two second plates 12 without the aid of the sleeve 4, thereby connecting the profiles extending in three different directions.

[0160] In this embodiment, a first positioning groove 34 is provided on the base 3, and a second positioning groove 35 is provided on the first plate 11 of the beam 1. The position of the first positioning groove 34 corresponds to the position of the second positioning groove 35. The edge of the sleeve 4 can pass through the second positioning groove 35 and be inserted into the first positioning groove 34, thereby realizing the positioning of the sleeve 4.

[0161] This embodiment also provides a battery swap station, including the above-mentioned frame assembly. By using the above-mentioned frame assembly, the battery swap station can have a relatively stable and reliable frame structure, and the battery swap station can be built quickly and conveniently. At the same time, the battery swap station composed of the above-mentioned frame assembly has the possibility and convenience of expansion in different directions due to its frame structure. In addition, since the box frame of the battery swap station is assembled, when the box frame of the battery swap station is partially damaged, the frame assembly and other components can be disassembled and the damaged parts can be replaced, which can improve the maintenance convenience of the battery swap station and reduce the maintenance cost.

[0162] Specifically, the battery swap station includes a first battery storage area, a second battery storage area, and a battery swap operation area located between the first and second battery storage areas. The frame assembly is constructed into a box frame of the first and second battery storage areas.

[0180] Move the engaging portion 71 of the connecting piece 7 from the first hole portion 61 of the cross beam 1 and the third hole portion 42 of the sleeve 4 into the fourth hole portion 43 which is in communication with the second hole portion 62 and the third hole portion 42 that are in communication with the first hole portion 61;

[0181] The connection gasket 5 is inserted from the first hole portion 61 and the third hole portion 42 in sequence along the insertion direction of the connection piece 7 of the side member 2 .

[0182] By using this method, three profiles extending in different directions can be connected together, and the operation is very simple, so that the frame assembly can be applicable to a wider range of frame assemblies.

[0183] Furthermore, the step of inserting the connecting piece 7 of the side beam 2 into the connecting hole 6 of the cross beam 1 from one side or both sides of the cross beam 1 also includes:

[0184] The positioning piece 8 of the side beam 2 is inserted into the third positioning groove 16 of the cross beam 1 to position the cross beam 1 when it is connected to the side beam 2 .

[0191] After the connecting piece 7 of the side beam 2 continues to move to the first hole portion 61 of the cross beam 1 connecting hole 6 and the third hole portion 42 of the reserved hole 41 of the sleeve 4, the side beam 2 is fixed to the base 3 through the second fixing portion;

[0192] After the engaging portion 71 of the connecting piece 7 is moved from the first hole portion 61 of the beam 1 and the third hole portion 42 of the sleeve 4 into the second hole portion 62 penetrating the first hole portion 61 and the fourth hole portion 43 penetrating the third hole portion 42, the beam 1 is fixed to the base 3 through the first fixing portion;

[0193] The connection spacer 5 is inserted from the first hole 61 along the insertion direction of the connection piece 7 of the side member 2 .

[0194] The sleeve 4 is fixed to the side beam 2 by using the third hole portion 42 and the fourth hole portion 43 . Therefore, the sleeve 4 is fixed without the aid of other process means or tools, and the connection is relatively convenient.
