[0033] Embodiment 1

[0034] like Figure 1-Figure 3 As shown, a bottom footing 1 of a battery swap station of the present invention comprises: a top plate 11, a bottom plate 12, and a support frame 13. The bottom plate 12 is arranged horizontally, the support frame 13 is fixedly arranged on the top of the bottom plate 12, the top plate 11 is arranged horizontally, the top plate 11 is fixedly arranged on the top of the support frame 13, the top plate 11 is parallel to the bottom plate 12, and the top plate 11 is located above the bottom plate 12, that is, the support frame 13 is fixedly arranged between the top plate 11 and the bottom plate 12. Among them, the projection of the top plate 11 on the top surface of the bottom plate 12 falls within the range of the top surface of the bottom plate 12, that is, the length of the edge of each side of the top plate 11 is less than or equal to the length of the edge of the corresponding side of the bottom plate 12. In this embodiment, the top plate 11 and the bottom plate 12 both adopt a rectangular plate structure, and the length of the edge of each side of the top plate 11 is less than the length of the edge of the corresponding side of the bottom plate 12, so that the area of ​​the bottom plate 12 is larger than the area of ​​the top plate 11, which increases the contact area between the overall equipment and the ground, can enhance the load-bearing effect and tensile resistance of the bottom pads, and can make the overall equipment firmly supported on the ground.

[0035] like Figure 1 and Figure 3 As shown, the support frame 13 includes a side plate 131 and a support vertical plate 132. There are two side plates 131, which are vertically and fixedly arranged between the top plate 11 and the bottom plate 12. The two side plates 131 are arranged opposite to each other, and the shapes and sizes of the two side plates 131 are consistent. The side plates 131 are fixedly connected to the top plate 11 and the bottom plate 12 by welding or threaded connection. In this embodiment, the side plates 131 are fixedly connected to the top plate 11 and the bottom plate 12 by welding.

[0036] like Figure 1 and Figure 3As shown, the side plate 131 is a trapezoidal plate structure, that is, the projection of the side plate 131 on the vertical plane is a trapezoid. For the convenience of description, in this embodiment, the projection is called a trapezoidal projection. The top of the side plate 131 is fixedly connected to the bottom end of the top plate 11, and the bottom of the side plate 131 is fixedly connected to the top of the bottom plate 12. The long side of the side plate 131 at the junction with the bottom plate 12 is greater than the long side of the side plate 131 at the junction with the top plate 11, that is, the length of the bottom side of the trapezoidal projection of the side plate 131 is greater than the length of the top side. The side plate 131 includes a top surface 131a, a bottom surface 131b, a first side surface 131c, and a second side surface 131d. The first side surface 131c and the second side surface 131d are arranged between the top surface 131a and the bottom surface. The top surface 131a, the bottom surface 131b, the first side surface 131c, and the second side surface 131d together form a trapezoidal edge. The first side surface 131c is an inclined surface, and the angle between the first side surface 131c and the bottom surface has a numerical range of 10°-45°. This angle range can keep the bottom edge of the side plate 131 within a reasonable length range, and can enhance the compressive strength of the side plate. In this embodiment, the angle between the first side surface 131c and the bottom surface is 24° to achieve the best compressive strength. The horizontal distance between the bottom end of the first side surface 131c and the side surface of the corresponding side of the bottom plate 12 has a numerical range of 5-15mm. In this embodiment, the horizontal distance between the bottom end of the first side surface 131c and the side surface of the corresponding side of the bottom plate 12 is 10mm. This size can ensure that when the side plate 131 and the bottom plate 12 are in maximum contact, a margin can be reserved for the welding between the side plate 131 and the bottom plate 12, that is, when the compressive strength of the side plate 131 is not affected, the appearance is ensured to be beautiful, and at the same time, it can be prevented from hooking the cable after it protrudes from the side of the bottom plate 12. Similarly, to prevent the top of the side plate 131 from protruding from the side of the top plate 11 and hooking the cable, the horizontal distance between the top of the first side 131c and the side of the corresponding side of the top plate 11 has a numerical range of 5-15mm. In this embodiment, the horizontal distance between the top of the first side 131c and the side of the corresponding side of the top plate 11 is 10mm. In addition, the first side 131c adopts a slope structure, which not only has the effect of enhancing the compressive strength of the side plate 131, but also can improve the stability of equipment installation, and can avoid cleaning dead corners. In addition, in order to avoid the wear of the cable when the lower part of the bottom pad 1 contacts the cable during long-term use, chamfers are set at the four top corners of the bottom plate 12 of this embodiment, and a transition surface is set between the bottom end of the first side 131c of the side plate 131 and the top surface of the bottom plate 12. The transition surface can be a slope inclined outward and downward, or a vertical surface. That is, the first side 131c and the four top corners of the bottom plate 12 do not have sharp corners.

[0037] like Figure 1 and Figure 2As shown, in the present invention, a plurality of connection holes 14 are provided on opposite sides of the bottom plate 12, and the connection holes 14 are located on the outer sides of the side plates 131 on the corresponding sides. That is, the connection holes 14 are provided on the installation side of the side plates 131 of the bottom plate 12, and the connection holes 14 are located on the side of the side plates 131 away from the other side plates 131, and the connection holes 14 are closer to the side of the corresponding side of the bottom plate 12 than the side plates 131 on the corresponding side. In addition, in order to strengthen the connection strength between the bottom foot 1 and the ground, the connection holes 14 can also be provided at the position between the two side plates 131 of the bottom plate 12. When installing the bottom foot 1, the bolts can be passed through the connection holes 14 and extended to the ground to fix the bottom foot 1.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, the support vertical plates 132 are vertically arranged, and the support vertical plates 132 are arranged between the two side plates 131, and the number of the support vertical plates 132 is one or more. Among them, when the number of the support vertical plates 132 is multiple, the stability of the bottom foot 1 can be better. When the number of the support vertical plates 132 is multiple, the multiple support vertical plates 132 are arranged in a direction parallel to the long side of the bottom surface of the side plate 131. In this embodiment, the number of the support vertical plates 132 is 2, and a closed chamber 15 is formed between the two support vertical plates 132, the two side plates 131, the top plate 11, and the bottom plate to enhance the stability of the bottom foot 1, and can save support materials while ensuring stability. An adjustment hole 111 is opened on the top plate 11. The adjustment hole 111 can be circular or oblong. In the present embodiment, the adjustment hole 111 is oblong and is a vertical through hole. The adjustment hole 111 is located outside the closed chamber 15. During installation, when the battery swap station body 2 needs to be adjusted, a tool can be used to lift up the battery swap station body 2 through the adjustment hole 111 before subsequent operations are performed. During subsequent disassembly, the battery swap station body 2 can also be lifted up through the hole.

[0039] Embodiment 2

[0040] like Figure 4-Figure 6 As shown, a battery swap station structure includes a battery swap station body 2, and a plurality of bottom pads 1 arranged at the bottom of the battery swap station body 2. The structure of the bottom pads 1 refers to the structure of the first embodiment and will not be repeated in this embodiment. The bottom plate 12 of the bottom pads 1 is fixedly connected to the ground 3 by bolts 21, and the top plate 11 of the bottom pads 1 is fixedly connected to the bottom of the battery swap station body 2 by welding. In this embodiment, the bolts 21 are either chemical bolts or anchor bolts, or a mixture of the two, to enhance the connection strength between the bottom pads 1 and the ground.

[0041] like Figure 1-Figure 2 ,as well as Figure 4-Figure 6As shown, in order to further realize the horizontal adjustment of the battery swap station body 2 to level the equipment, a leveling pad 4 is arranged between the bottom plate 12 of the bottom pad 1 and the ground 3, and a horizontal substrate for connecting the leveling pad 4 is arranged on the ground 3 at the site to make the upper surface of the ground 3 flat, so as to facilitate the installation of the leveling pad 4. Among them, the number of the bottom pads 1 is multiple, and the multiple bottom pads 1 are divided into two groups, and the two groups of bottom pads 1 are respectively located on both sides of the width direction of the bottom of the battery swap station body 2. The bottom end of the first side surface 131c of the side plate 131 of the bottom pad 1 faces the outside of the battery swap station body 2, which can further improve the stability of the battery swap station structure and prevent it from hooking the cable.

[0042] In the present utility model, the contact area between the battery swap station body 2 and the ground 3 is increased by the cooperation of the bottom plate 12 and the trapezoidal side plate 131, which can enhance the load-bearing effect and tensile resistance of the bottom pad 1, and can firmly support the battery swap station body 2 on the ground 3. The bottom pad 1 is set between the battery swap station body 2 and the ground 3. The installation height of the battery swap station body 2 can be raised by setting the bottom pad 1, so that the cable can be pulled into the bottom of the battery swap station body 2 from the side, without digging a cable trench, and the charger can be directly connected from the cable opening at the bottom of the battery swap station body 2. Although the bottom pad 1 of the present utility model has a simple structure, it can avoid digging a cable trench while ensuring the stability of the equipment, simplify the construction process, reduce labor costs, and thus shorten the construction period.

[0043] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
