DETAILED DESCRIPTION

[0026] The present disclosure will now be discussed with reference to a number of example embodiments. It should be appreciated that these embodiments are discussed only to better illustrate the present disclosure and, as such, should not be taken as limiting the scope of the present disclosure.

[0027] As used herein, the term "includes" and its variants are to be read as open-ended terms that mean "includes, but is not limited to." The term "based on" is to be construed as "based at least in part on." The terms "one embodiment" and "an embodiment" are to be read as "at least one embodiment." The term "another embodiment" is to be read as "at least one other embodiment." The terms "upper," "lower," "left," "right," "front," "rear," "top," "bottom," "inner," "outer," "vertical," "horizontal," "lateral," "longitudinal," and similar terms are used for orientation or positional relationships based on the orientation or position as shown in the drawings. These terms are used merely for the sake of description and are not intended to limit the devices, elements, or components to the particular orientation or configuration shown in the drawings. In addition, these terms are used as terms of convenience and are used to more particularly emphasize certain claimed subject matter over other claimed subject matter. However, these terms are used in connection with a specific embodiment and are not intended to limit the particular orientation or configuration shown in the drawings or described within this application. Furthermore, terms such as "mount," "set," "provided with," "connected," and "linked" are to be construed broadly. For example, it can be fixed connection, detachable connection, or integral configuration; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through an intermediate medium; or it can be internal connection between two devices, elements, or components. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances. In addition, the terms "first," "second," and the like are mainly used to distinguish different devices, elements, or components (the specific types and configurations can be the same or different), and are not intended to indicate or imply the relative importance and quantity of the indicated devices, elements, or components. Unless otherwise stated, the meaning of "multiple" is two or more.

[0028] In the embodiment, the assembly factory has special equipment to assemble the battery swap station. If each component of the battery swap station is transported to the installation site separately, the installation site may not have professional equipment, resulting in difficulty in assembly. Therefore, the battery swap station is directly transported to the destination after being assembled, thereby improving the installation efficiency of the battery swap station. However, if the assembled battery swap station is transported, the height of the vehicle and the battery swap station will be limited when passing through bridges or tunnels and the like. The height of the heavy truck is relatively fixed, so it is necessary to limit the height of the battery swap station during transportation. In addition, after transportation to the destination, the ground flatness of the installation site has a high requirement. The flat ground has a long construction period, high cost, and low installation efficiency of the battery swap station. Therefore, in order to solve the above problems, the utility model provides a battery swap station, as shown in the figure, which can include a box assembly 01 and a support assembly 02. Figure 1

[0029] As​Figure 1 As shown, the box assembly 01 is an important part of the battery swap station, which can supplement the energy of the vehicle that needs to be swapped, and also can avoid the influence of external environmental factors on the inside of the box assembly 01. The surrounding space of the box assembly 01 can accommodate battery units.

[0030] The support assembly 02 can include a plurality of support units 22. The plurality of support units 22 can be arranged at intervals along the bottom of the box assembly 01, and the distance between two adjacent support units 22 can be greater than the length of the support unit 22, so as to avoid mutual interference between two adjacent support units 22 in subsequent operations. The support unit 22 can include a first support part 221 and a support module 222. One end of the first support part 221 can be hinged to the bottom of the box assembly 01, and the other end can be movably connected to the end of the support module 222 away from the box assembly 01. In this way, the support unit 22 can support the box assembly 01, so that the box assembly 01 is spaced apart from the ground, avoiding the box assembly 01 from being damp. When the ground where the battery swap station is installed is not flat, or after the battery swap station is installed, the local ground will settle due to the weight of the battery swap station, causing the battery swap station to tilt. According to the ground conditions, each support module 222 can be moved along the length direction of the first support part 221, so that the box assembly 01 is adjusted to a horizontal state, so that when the vehicle performs the battery swap action, the battery swap process can be avoided. Abnormal, that is, when the relative position between the battery swap station and the vehicle to be swapped deviates, the battery swap station cannot perform the battery swap action, and also can avoid the internal structure from being offset, causing the line connection to be loose, poor contact and other problems, thereby improving the overall safety.

[0031] The battery swap station can include a transportation state and an installation state. In the transportation state, the end of the support unit 22 away from the box assembly 01 is moved towards the box assembly 01 to a maximum size of the battery swap station along the direction from the box assembly 01 to the support assembly 02, which is a first size. Since the heavy truck transports the battery swap station, there is a certain limit on the height of the combination of the vehicle and the battery swap station when passing through special places such as bridges or tunnels during driving. The height of the heavy truck is relatively fixed, so it is necessary to reduce the height of the battery swap station during transportation to make the battery swap station pass through most of the roads. Since the distance between the two adjacent support units 22 can be greater than the length of the support unit 22, and one end of the first support part 221 is hinged to the bottom of the box assembly 01, the end of the support unit 22 away from the box assembly 01 can be moved towards the box assembly 01, thereby reducing the height of the battery swap station and facilitating the transportation of the battery swap station by the transportation equipment. In the installation state, the end of the support unit 22 away from the box assembly 01 is moved away from the box assembly 01 to a maximum size of the battery swap station along the direction from the box assembly 01 to the support assembly 02, which is a second size greater than the first size. When the battery swap station arrives at the destination and needs to be installed, the end of the support unit 22 away from the box assembly 01 can be moved away from the box assembly 01, so that the length direction of the box assembly 01 is perpendicular to the length direction of the support unit 22, and the support unit 22 can support the box assembly 01. Then, according to the flatness of the ground, the distance from the end of the first support part 221 close to the box assembly 01 to the end of the support module 222 away from the box is adjusted, so that the box assembly 01 is in a horizontal state, thereby preventing the battery swap station and the vehicle to be swapped from deviating from the relative position during the battery swapping process, so that the vehicle cannot be powered.

[0032] In this embodiment, as shown in Figure 2 The support module 222 can include a second support part 2221 and a third support part 2222. One end of the second support part 2221 can be movably connected to the end of the first support part 221 away from the box assembly 01, and the other end can be detachably connected to the third support part 2222. The second support part 2221 can move along the length direction of the first support part 221, so that when the battery swap station is in the installation state, the second support part 2221 can be used to level the box assembly 01. The area of the side of the third support part 2222 away from the box assembly 01 can be greater than a preset area. The preset area is greater than the cross-sectional area of the first support part 221 towards the box assembly 01, so that when the battery swap station lands, the third support part 2222 contacts the ground with a larger area, thereby making the battery swap station more stable. The shape of the third support part 2222 in the projection direction towards the box assembly 01 is as shown in Figure 2As shown, the width of the first support part 221 is the same as the width of the third support part 2222, so that the side of the first support part 221 can bear the weight when the battery swap station is in the transportation state, so that the third support part 2222 will not be damaged during transportation, and the side area of the first support part 221 is large, the first support part 221 is reasonable in force and good in bearing capacity.

[0033] In the embodiment, as shown in Figure 3 As shown, the support assembly 02 can further include a shell unit 23. The shell unit 23 can be movably connected with the first support part 221. Since the battery swap station needs to be leveled during installation, leveling requires relative movement of the first support and the second support, and the movable connection can allow the shell to always fit around the outer peripheral surface of the second support part 2221. The inner peripheral surface of the shell unit 23 can be fitted around the outer peripheral surface of the first support part 221. The inner peripheral surface of the shell unit 23 can be fitted around the outer peripheral surface of the second support part 2221. In this way, the bottom of the shell unit 23 can be moved to abut the side of the third support part 2222 close to the box assembly 01, so that the accumulated water on the ground can be prevented from entering the enclosed space of the shell unit 23, preventing the second support part 2221 from rusting and affecting the movement of the second support part 2221 along the length direction of the first support part 221, and the service life of the second support part 2221 can be prolonged.

[0034] In the embodiment, as shown in Figure 4 As shown, the support assembly 02 can further include a locking unit 21. The locking unit 21 can be detachably connected with the box assembly 01. The transportation state can further include that one end of the first support part 221 away from the box assembly 01 is detachably connected with the locking unit 21, so that when the battery swap station is in the transportation state, one end of the support unit 22 away from the box assembly 01 moves towards the box assembly 01, and the locking unit 21 can fix the moved support unit 22, avoiding loosening of the moved support unit 22 when the hoisting equipment moves the battery swap station to the transportation equipment, so that when the battery swap station is moved to the heavy truck, the support unit 22 is damaged.

[0035] In the embodiment, as shown in Figure 1As shown, the box assembly 01 can include a first cabin unit 11 and a second cabin unit 12. The first cabin unit 11 and the second cabin unit 12 can be detachably connected in sequence. A part of the support unit 22 is hinged to the bottom of the first cabin unit 11, and another part is hinged to the bottom of the second cabin unit 12. The first cabin unit 11 can be used to park a vehicle, so that the battery swap station can swap the battery of the vehicle. The second cabin unit 12 can store battery units and supplement the energy of the battery units. The transportation state includes moving the end of the support unit 22 away from one end of the box assembly 01 towards the direction of the first cabin unit 11 and the second cabin unit 12 respectively, and the installation state includes moving the end of the support unit 22 away from one end of the cabin unit towards the end away from the first cabin unit 11 and the second cabin unit 12 respectively.

[0036] In other embodiments, as Figure 1 shown, the box assembly 01 further includes an ear unit 13, which is detachably connected to the first cabin unit 11 and the second cabin unit 12. When the battery swap station needs to be transported, the hoisting equipment can move the battery swap station onto the transportation equipment through the ear unit 13, thereby facilitating the movement and transportation of the battery swap station.

[0037] In this embodiment, as Figure 1 , Figure 5 shown, the first cabin unit 11 can include a cabin top 111, a cabin side 112, and a connecting part 113. One end of the cabin top 111 can be detachably connected to the second cabin unit 12, and the other end can extend away from the second cabin unit 12. One end of the cabin side 112 can be detachably connected to the end of the cabin top 111 away from the second cabin unit 12, and the other end can extend towards the support unit 22. One end of the support unit 22 can be hinged to the bottom of the cabin side 112, and the other end can extend away from the cabin top 111.

[0038] The transportation state can further include that one end of the connecting part 113 is detachably connected to the cabin side 112, and the other end is detachably connected to the second cabin unit 12. The installation state can further include that the connecting part 113 is arranged separately from the cabin side and the second cabin unit 12. When hoisting the battery swap station, one end of the connecting part 113 is connected to the cabin side 112, and the other end is connected to the second cabin unit 12, thereby increasing the stability of the cabin side, and avoiding damage to the cabin top 111 and the cabin side 112 during hoisting. When the battery swap station is transported to the destination and installed, the cabin side 112 is connected to the ground through the support unit 22, thereby having a certain stability. Therefore, after the installation of the battery swap station is completed, the connecting part 113 is removed from the cabin side 112 and the second cabin unit 12, and the vehicle can move in the space between the cabin side 112 and the second cabin unit 12 during battery swapping.

[0039] In the embodiment, as shown in Figure 1 The second cabin unit 12 can include a cabin body 121 and a ventilation part 122. The ventilation part 122 is detachably connected with the cabin body 121, and the bottom of the cabin body 121 is hinged with the support unit 22. The space surrounded by the cabin body 121 is communicated with the outside space of the cabin body 121 through the ventilation part 122, and the ventilation part 122 is spaced apart from the support unit 22, so that the temperature in the space surrounded by the cabin body 121 can be prevented from being too high to cause a safety hazard.

[0040] In the embodiment, the second cabin unit 12 can further include a dustproof door 123. The dustproof door 123 is movably connected with the cabin body 121 near one end of the cabin body 121 close to the first cabin unit 11. The dustproof door 123 includes an open state and a closed state. In the open state, the space surrounded by the second cabin unit 12 is communicated with the space surrounded by the first cabin unit 11 through the dustproof door 123. In the closed state, the dustproof door 123 forms a space with the cabin body 121. Therefore, when a vehicle in need of battery replacement is driven into the space surrounded by the first cabin unit 11, the dustproof door 123 is in the open state, the battery unit on the vehicle is moved into the second cabin, and then the fully charged battery unit in the second cabin unit 12 is moved to the vehicle, so that the battery replacement of the vehicle is completed. When there is no vehicle in need of battery replacement, the dustproof door 123 is in the closed state, so that foreign matters can be prevented from entering the space surrounded by the second cabin unit 12.

[0041] In the embodiment, the box assembly 01 can include a battery unit. The battery unit is detachably connected with the second cabin unit 12. The battery unit is electrically connected with the second cabin unit 12. The battery unit is arranged in the space surrounded by the second cabin unit 12. The second cabin unit 12 can protect the battery unit from the influence of the external environment, and the low-power battery unit taken out from the vehicle can be charged in the space surrounded by the second cabin unit 12, so that the subsequent vehicle can be prepared for sufficient power supply, and the battery unit of the vehicle in need of power supply can be replaced, so as to ensure the normal driving of the vehicle. When the battery replacement station is in a transportation state, the battery unit can be placed in the space surrounded by the second cabin unit 12, so that the battery unit is transported together with the second cabin unit 12, thereby further improving the installation efficiency of the battery replacement station.

[0042] In the embodiment, the box assembly 01 can further include a grabbing unit. The grabbing unit is movably connected with the first cabin unit 11 and the second cabin unit 12. When a vehicle needs to be powered, the grabbing unit can move the battery unit on the vehicle into the second cabin unit 12 for charging, so that the subsequent vehicle can be prepared for sufficient power supply, and then the fully charged battery unit in the space surrounded by the second cabin unit 12 is moved to the vehicle, so that the battery replacement of the vehicle is completed.

[0043] It is understood by those of ordinary skill in the art that the above-mentioned embodiments are specific cases for implementing the present disclosure, and in actual applications, various changes can be made in form and details without departing from the scope of the present disclosure.
