[0051] Some embodiments of the present disclosure provide an outdoor power supply 1000, such as Figure 1 and Figure 2 As shown, the outdoor power supply 1000 includes a bottom case 100 , an output panel assembly 200 , a battery module 300 , a top case 400 and an inverter 500 .

[0052] The top case 400 is disposed on one side of the battery module 300. The top case 400 includes a first sub-case 410 and a second sub-case 420. The first sub-case 410 is located on a side of the second sub-case 420 away from the battery module 300. Figure 3 As shown, the second sub-shell 420 includes a bottom wall 426 and a plurality of side walls 427 disposed around the bottom wall, the bottom wall 426 and the plurality of side walls 427 form a receiving groove with an opening, the first sub-shell 410 is disposed at the opening and closes the receiving groove.

[0053] A plurality of heat dissipation holes 421 are provided on the plurality of side walls 427. The plurality of heat dissipation holes 421 form a heat dissipation area. For example, Figure 3As shown, four heat dissipation areas are arranged on the multiple side walls 427, and every two heat dissipation areas are located on the same side wall 427. The two side walls with the heat dissipation areas are opposite to each other. The heat generated by the battery module 300 can be dissipated into the air through the heat dissipation holes 421. In this way, the heat dissipation holes 421 can improve the heat dissipation efficiency of the outdoor power supply 1000, so as to reduce the temperature of the battery module 300 and increase the service life of the battery module 300.

[0054] The second subshell 420 also includes a plurality of first plates 428 extending in a direction perpendicular to the bottom wall 426 and a plurality of second plates 429 extending in a direction perpendicular to the bottom wall 426. The two first plates 428 are respectively located on both sides of a heat dissipation area, and the two first plates 428 are located between a second plate 429 and a side wall 427. The two first plates 428, a second plate 429, the bottom wall 426 and a side wall 427 form a fan mounting slot 422. By way of example, the number of the fan mounting slots 422 is equal to the number of the heat dissipation areas.

[0055] The outdoor power supply 1000 also includes a plurality of fans 600. For example, the number of fans 600 can be 3, 4 or 5, and the embodiments of the present disclosure are no longer listed one by one. For example, the number of fans 600 is 4. A plurality of fans 600 are located in the receiving groove. When installing, the fan 600 can be inserted from the top of the fan mounting groove 422 to complete the installation of the fan 600 and the second sub-shell 420. In the case where the fan 600 is located in the fan mounting groove 422, each fan 600 is opposite to at least one heat dissipation hole 421, which means that each fan 600 is opposite to a heat dissipation area, and the fan 600 can pass the heat in the outdoor power supply 1000, and the heat dissipation hole 421 included in the heat dissipation area opposite thereto blows out the outdoor power supply 1000, so that the fan 600 can further improve the heat dissipation efficiency of the outdoor power supply 1000, reduce the temperature of the battery module 300, and increase the service life of the battery module 300. A plurality of fans 600 are electrically connected to the battery module 300, and the battery module 300 is used to provide power for the fan 600 to rotate.

[0056] In some embodiments, two transport slots 423 are provided on the plurality of side walls 427, so that the user can conveniently carry the outdoor power supply 1000. Two transport slots 423 are provided on the plurality of side walls 427, which means that one side wall 427 is provided with one transport slot 423, and the two side walls provided with the transport slots 423 are opposite.

[0057] The output panel assembly 200 includes multiple interfaces, and illustratively, the multiple interfaces may be one or more of an AC socket, a DC socket, an aviation plug, and a cigarette lighter. The output panel assembly 200 is electrically connected to the battery module 300. When the output panel assembly 200 includes a cigarette lighter, the outdoor power supply 1000 can output power to an external device (such as a mobile phone, a tablet computer, and a game console).

[0058] In some embodiments, the output panel assembly 200 further includes an overload protection device, so as to reduce the risk of overload output of the output panel assembly 200 and the battery module 300.

[0059] The bottom shell 100 is arranged on a side of the battery module 300 away from the top shell 400, and the surfaces of the top shell 400 and the bottom shell 100 close to each other are in contact, so that the bottom shell 100 and the top shell 400 completely protect the battery module 300, reducing the risk of damage to the battery module 300 due to bumps.

[0060] The inverter 500 is electrically connected to the battery module 300. The inverter 500 is used to convert direct current into constant frequency and constant voltage or frequency and voltage regulated alternating current. When the output voltage of the battery module 300 is 12V (volts), the inverter can convert 12V direct current into alternating current with a voltage of 220V and a frequency of 50HZ (hertz).

[0061] The outdoor power supply 1000 may also include a rectifier (not shown in the figure), which is electrically connected to the battery module 300. When the outdoor power supply 1000 is out of power, it can be electrically connected to the mains power grid through the rectifier to convert the 220V, 50HZ AC power provided by the mains power grid into DC power, and then charge the battery module 300.

[0062] The outdoor power supply 1000 also includes a plurality of anti-skid pads 700 , and at least one anti-skid pad 700 is disposed in each transport slot 423 . Thus, during transport, the risk of the outdoor power supply 1000 colliding with the ground due to user slipping can be reduced, thereby damaging the battery module 300 .

[0063] The outdoor power supply 1000 further includes a plurality of foot pads 800, which are located on a side of the bottom shell 100 away from the top shell 400 and connected to the bottom shell 100. In this way, the friction between the ground and the bottom shell 100 can be reduced, and the service life of the bottom shell 100 can be improved.

[0064] In some implementations, such as Figure 4 As shown, the battery module 300 includes at least two battery packs 310, and the number of the battery packs 310 may be 2, 3, or 4. Exemplarily, the number of the battery packs 310 is 2.

[0065] like Figure 5As shown, the battery pack 310 includes a bracket 10 and a plurality of batteries 20. Figure 6 and Figure 7 As shown, the bracket 10 includes a base plate 11 and a plurality of groups of connecting columns 12 .

[0066] In some embodiments, the base plate 11 is rectangular in shape and is provided with a plurality of battery mounting holes 111 for placing the batteries 20 . There are intervals between adjacent battery mounting holes 111 , and the intervals are used to provide space for setting up a plurality of groups of connecting columns 12 . In this way, the plurality of groups of connecting columns 12 can be located in the intervals between the battery mounting holes 111 .

[0067] Exemplarily, the plurality of battery mounting holes 111 are arranged in a plurality of rows and columns, each row includes a plurality of battery mounting holes 111 arranged along the second direction X, and each column includes a plurality of battery mounting holes 111 arranged along the first direction Y.

[0068] In the case where the bracket 10 is used to fix multiple batteries 20, two brackets 10 are required, and the multiple batteries 20 are located between the two brackets 10, and the two ends of each battery 20 are respectively located in a battery mounting hole 111 of one bracket 10, and the two brackets 10 are arranged opposite to each other and are rotationally symmetrical about the reference axis. In this way, the two brackets 10 can clamp and fix the battery 20. One of the two brackets 10 is the first bracket 101, and the other is the second bracket 102, and the first bracket 101 is flipped 180°, along the first direction Y, the two ends of the first bracket 101 are flush with the two ends of the second bracket 102, and along the second direction X, the two ends of the first bracket 101 are flush with the two ends of the second bracket 102. Among them, the two ends of each battery 20 are respectively located in a battery mounting hole 111 of a bracket 10 means that one end of a battery 20 is located in a battery mounting hole 111 of the first bracket 101, and the other end is located in a battery mounting hole 111 of the second bracket 102.

[0069] A plurality of groups of connection posts 12 are disposed on the bottom plate 11 , and each group of connection posts 12 includes a first connection post 121 and a second connection post 122 .

[0070] The axis of the first connecting column 121 and the axis of the second connecting column 122 are perpendicular to the bottom plate 11 and are symmetrical with respect to the first reference plane P1. Figure 8~Figure 10 As shown, the axis of each first connecting column 121 on the first bracket coincides with the axis of a second connecting column 122 on the second bracket. The axis of the second connecting column 122 on the second bracket coincides with the axis of a first connecting column 121 on the first bracket.

[0071] The end of the first connecting column 121 away from the bottom plate 11 is provided with a mounting groove 1211, and the radial dimension of the end of the second connecting column 122 away from the bottom plate 11 is smaller than the radial dimension of the mounting groove 1211, so that the end of the second connecting column 122 on the first bracket 101 away from the bottom plate 11 can be inserted into the mounting groove 1211 on the first connecting column 121 on the second bracket 102, and connected to the first connecting column 121. The end of the second connecting column 122 on the first bracket away from the bottom plate 11 can be inserted into the mounting groove 1211 on the first connecting column 121 on the second bracket, and connected to the first connecting column 121. The bottom plate on the first bracket 101 and the bottom plate 11 on the second bracket 102 clamp the battery through the first connecting column 121 and the second connecting column 122. In this way, the risk of the two ends of the flipped bracket 10 and the two ends of the non-flipped bracket 10 not being flush due to accidentally touching the bottom plate 11 can be reduced. In this way, two brackets 10 with the same structure can fix and clamp multiple batteries 20, and the two brackets 10 (the first bracket 101 and the second bracket 102) required for the battery pack 310 can be manufactured by one mold, which can reduce the manufacturing cost of the bracket.

[0072] The first reference plane P1 is perpendicular to the bottom plate 11 and passes through the midline of the bottom plate 11 extending along the first direction Y. The midline of the bottom plate 11 extending along the first direction Y refers to: a line connecting the midpoints of the two sides of the bottom plate 11 along the first direction Y and along the second direction X. The first direction Y is parallel to the width direction of the bottom plate 11, and the first direction Y and the second direction X are perpendicular.

[0073] In order to make the bottom plate 11 bear force uniformly, the plurality of connecting columns 12 are also rotationally symmetric about the first center line X1 . The first center line X1 is perpendicular to the bottom plate 11 and passes through the midpoint of the midline of the bottom plate 11 extending along the first direction Y.

[0074] For example, Figure 6 11, the midline of the bottom plate 11 extending along the first direction Y and the midline of the bottom plate 11 extending along the second direction X divide the bottom plate 11 into four areas, which are named as the first area 112, the second area 113, the third area 114 and the fourth area 115. The midline of the bottom plate 11 extending along the second direction X refers to: a line connecting the midpoints of the two sides of the bottom plate 11 along the second direction X and along the first direction Y.

[0075] like Figure 6As shown, the first area 112 is located at the upper left part of the bottom plate 11, the second area 113 is located at the upper right part of the bottom plate 11, the third area 114 is located at the lower left part of the bottom plate 11, and the fourth area 115 is located at the lower right part of the bottom plate 11. The multiple groups of connecting columns 12 in the first area 112 and the multiple groups of connecting columns 12 in the third area 114 are rotationally symmetric about the first center line X1, and the multiple groups of connecting columns 12 in the second area 113 and the multiple groups of connecting columns 12 in the fourth area 115 are rotationally symmetric about the first center line X1. In this way, the force on the bottom plate 11 can be more uniform, and the service life of the bottom plate 11 can be improved.

[0076] When multiple groups of connecting columns 12 are rotationally symmetrical about the first center line X1, the axis of the first connecting column 121 in the first area 112 and the axis of the second connecting column 122 in the second area 113, the axis of the second connecting column 122 in the first area 112 and the axis of the first connecting column 121 in the second area 113, the axis of the first connecting column 121 in the third area 114 and the axis of the second connecting column 122 in the third area 114, and the axis of the second connecting column 122 in the third area 114 and the axis of the first connecting column 121 in the third area 114 are all symmetrical about the midline of the base plate 11 extending along the first direction Y.

[0077] In the case where the bracket 10 is used to fix multiple batteries 20, one of the brackets 10 can be rotated 180° with the first direction Y as the rotation axis. At this time, the first area 112 of the first bracket 101 corresponds to the second area 113 of the second bracket 102, the second area 113 of the first bracket 101 corresponds to the first area 112 of the second bracket 102, the third area 114 of the first bracket 101 corresponds to the fourth area 115 of the second bracket 102, and the fourth area 115 of the first bracket 101 corresponds to the third area 114 of the second bracket 102. One of the brackets 10 can also be rotated 180° with the second direction X as the rotation axis. At this time, the first area 112 of the first bracket 101 corresponds to the third area 114 of the second bracket 102, the third area 114 of the first bracket 101 corresponds to the first area 112 of the second bracket 102, the second area 113 of the first bracket 101 corresponds to the fourth area 115 of the second bracket 102, and the fourth area 115 of the first bracket 101 corresponds to the second area 113 of the second bracket 102. In this way, when installing the bracket 10, there is no need to rotate one of the brackets 10 along a specific direction, which makes it more convenient to install the bracket 10 and can reduce the installation time.

Along the second reference line X3, 3 first connecting posts 121 and 3 second connecting posts 122 are alternately distributed.

[0080] For example, in order to connect the second bracket 102 to the first bracket 101, as shown in FIG.

The third direction Z is parallel to the thickness direction of the bottom plate 11.

One end of the second reinforcing rib 1222 is adjacent to the bottom plate 11, and the dimension of the second reinforcing rib 1222 along the third direction Z is smaller than the dimension of the second column 1221 along the third direction Z. In this way, the second connecting column 122 can be inserted into the mounting groove 1211. The plurality of second reinforcing ribs 1222 can improve the strength of the second connecting column 122.

[0085] The distance between one end of the second reinforcing rib 1222 away from the bottom plate 11 and one end of the second column 1221 away from the bottom plate 11 is greater than or equal to the dimension of the mounting groove 1211 along the third direction Z. In this way, the surface of the second connecting column 122 away from the bottom plate 11 can contact the surface of the mounting groove 1211 close to the bottom plate 11.

The second connector 320 includes a screw 3201 and a nut 3202. The third connection column 13 can reduce the risk of deformation of the second connector 320.

[0088] Exemplarily, the number of the third connecting pillars 13 is four, and the four third connecting pillars 13 are arranged into two rows of third connecting pillars 13 and two columns of third connecting pillars 13. Each row of third connecting pillars 13 includes two third connecting pillars 13 arranged along the second direction X, and the two third connecting pillars 13 included in each row of third connecting pillars 13 are symmetrical about the first reference plane P1.

The third connector can be a screw. The battery module 300 is fixed to the second sub-shell 420 by the bracket 10. Compared with placing the battery module 300 directly in the shell, the weight of the battery module 300 can be reduced, and the risk of falling off from the shell and colliding with the ground, resulting in damage to the battery module 300, can be reduced.

[0093] In some embodiments, Fig.13 As shown, the bracket 10 further includes a plurality of connection structures, which are arranged on at least one side wall of the bottom plate 11 extending along the second direction X. Exemplarily, the plurality of connection structures include a first connection structure 15, the first connection structure 15 includes a third threaded hole 151, and the third threaded hole 151 is arranged on a side of the bottom plate 11 away from the protrusion 14 along the first direction Y.

[0094] like Fig.10 As shown, the bracket 10 also includes a fourth connecting column 16, which is located on the side of the base plate 11 away from the protrusion 14, the extension direction of the fourth connecting column 16 is parallel to the first direction Y, one end of the fourth connecting column 16 is connected to the base plate 11, and the third threaded hole 151 is set on the fourth connecting column 16.

In this way, the battery module 300 is fixedly connected to the bottom shell 100 through the bracket 10 and the top shell 400, which can make the outdoor power supply 1000 more stable.

[0097] In some embodiments, Figure 6 As shown, the bracket 10 also includes multiple groups of guide columns 17, each group includes multiple guide columns 17, and the multiple guide columns 17 are arranged around a battery mounting hole 111.

Along the third direction Z and away from the bottom plate 11, the outer diameter of the guide column 17 gradually decreases. In this way, when the battery 20 is installed in the battery mounting hole 111, the guide column 17 can make it easier for the battery 20 to slide into the battery mounting hole 111, thereby making the process of installing the battery 20 into the battery mounting hole 111 more convenient. The installation time can be reduced.

[0098] Exemplarily, the boundary where the guide column 17 intersects the bottom plate 11 is tangent to the boundary of the battery mounting hole 111 close to the multiple groups of connecting columns 12 , further facilitating the battery 20 to slide into the battery mounting hole 111 .

[0099] In some embodiments, at least one guide post 17 is included between two adjacent battery mounting holes 111, and the two adjacent battery mounting holes 111 share at least one guide post 17.

[0106] In some embodiments, the first pole tab 30 and the second pole tab 40 both include a first extension portion 70, and the extension direction of the first extension portion 70 is parallel to the third direction Z. The plurality of connection structures further include a first positioning groove 18, the first positioning groove 18 extends along the third direction Z, and along the second direction X, the first positioning groove 18 is provided at one end of the bracket 10. The first extension portion 70 can be inserted into the first positioning groove 18. When the first extension portion 70 is inserted into the first positioning groove 18, the first pole tab 30 and the second pole tab 40 are both aligned with the positive and negative poles of the plurality of batteries 20, so that the installation time of the battery pack 310 can be reduced, making the installation process more convenient and quick.

[0107] In some embodiments, Figure 3 As shown, at least two battery packs 310 are stacked along a direction perpendicular to the bracket 10 of the battery pack 310 , which means that at least two battery packs 310 are stacked along the third direction Z.

The battery management circuit board 330 is located on one side of the side wall of the bracket 10 extending along the second direction X, and is provided with a first mounting hole 3301. Fig.13 As shown, the bracket 10 further includes a plurality of connection structures, the plurality of connection structures including a second connection structure 19, and the second connection structure 19 includes at least one fourth threaded hole 1005.

[0109] In some embodiments, Fig.13 As shown, the second connection structure 19 further includes a fifth connection column 191 and a sixth connection column 192. The fifth connection column 191 and the sixth connection column 192 are located on the same side of the bottom plate 11 as the two protrusions 14.

[0110] The fifth connecting column 191 extends along the first direction Y, and one end is connected to the bottom plate 11, and the fourth threaded hole 1005 is provided on the fifth connecting column 191. The fifth connecting column 191 includes a first section 1911 and a second section 1912, the outer diameter of the first section 1911 is smaller than the outer diameter of the second section 1912, and the first section 1911 is farther away from the bottom plate 11 than the second section 1912.

The second connecting structure 19 includes a fifth threaded hole 1007, which is provided on the sixth connecting column 192, and the diameter of the fifth threaded hole 1007 is greater than the diameter of the fourth threaded hole 1005. The dimension of the second section 1912 along the first direction Y is less than or equal to the dimension of the sixth connecting column 192 along the first direction Y, so that the battery management circuit board 330 can pass through the first section 1911 and contact the surface of the fifth connecting column 191 away from the bottom plate 11.

[0112] The sizes of the battery management circuit boards 330 installed in the battery modules 300 of different sizes are different, and the sizes of the mounting holes of the battery management circuit boards 330 of different sizes may be different. There are two types of battery management circuit boards 330 with the sizes of the first mounting holes 3301. The battery management circuit board 330 with the smaller size of the first mounting hole 3301 is named as the first circuit board, and the battery management circuit board 330 with the larger size of the first mounting hole 3301 is named as the second circuit board. The size of the first mounting hole 3301 of the first circuit board matches the fourth threaded hole 1005, and the size of the first mounting hole 3301 of the second circuit board matches the fifth threaded hole 1007. And the first mounting hole 3301 of the second circuit board matches the first section 1911 on the fifth connecting column 191, that is, the second circuit board can pass through the first section 1911 on the fifth connecting column 191, and the second circuit board cannot translate.

[0114] When the second circuit board is installed in the battery module 300, the first mounting hole 3301 on the second circuit board passes through the first section 1911, so that the fifth connecting column 191 on the first bracket 101 and the second bracket 102 prevents the second circuit board from moving (translation and rotation), and the fifth connecting column 191 plays a positioning role at this time. The second circuit board contacts the end of the sixth connecting column 192 away from the bottom plate 11. The battery module 300 also includes a plurality of fifth screws (not shown in the figure), which connect the battery pack 310 to the second circuit board through the first mounting hole 3301 and the fifth threaded hole 1007.

The battery module 300 also includes a plurality of sixth connecting members 1008 (as shown in FIG. Figure 4 As shown), the sixth connecting member 1008 passes through the second mounting hole and the sixth threaded hole 51 and is connected to the connecting piece 340.

[0118] The bracket 10 also includes a seventh connecting column 6, which is located on one side of the base plate 11 close to the protrusion 14. The extension direction of the seventh connecting column 6 is parallel to the first direction Y. One end of the seventh connecting column 6 is connected to the base plate 11. The seventh connecting column 6 is located in the middle of the two protrusions 14. The seventh connecting column 6 includes a seventh threaded hole 61.

[0119] like Figure 3As shown, the second sub-shell 420 includes at least one sixth connection hole, which is disposed on the bottom wall 426 , and the number of the sixth connection holes may be 1, 2, or 3. For example, the number of the sixth connection holes is 2.

[0120] The outdoor power supply 1000 further includes at least one seventh connection member 1009, the number of which is equal to the number of the sixth connection holes, and the seventh connection member 1009 sequentially connects the second sub-shell 420 and the battery module 300 through the sixth connection hole and the seventh threaded hole 61. In this way, the top shell 400 and the battery module 300 can be made more secure.

[0121] In some embodiments, Figure 7 As shown, the plurality of connection structures further include a plurality of positioning bars 7, and the number of the positioning bars 7 may be 2, 4 or 6. For example, the number of the positioning bars 7 is 2.

In this way, the connecting piece 340 can be placed in the interval between the two positioning bars 7, and the positioning bars 7 can reduce the risk of the connecting piece 340 moving along the second direction X.
