For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0022] like Figure 1As shown, a battery box provided in one embodiment of this application includes a box body 100, a box cover 200 and a box lock 300. The box body 100 is used to accommodate batteries, the box cover 200 is used to cover the box body 100, and the box lock 300 is used to fix the box cover 200 to the box body 100.

[0023] like Figure 6 As shown, the main body 100 of the box is provided with a receiving cavity 110 and a box opening 120 communicating with the receiving cavity 110.

[0024] Specifically, the main body 100 is a hollow structure with a receiving cavity 110 for accommodating batteries; the opening 120 is located at the top of the main body 100. Of course, in other embodiments, the opening 120 can also be located at other positions on the main body 100, such as the side of the main body 100. The opening 120 communicates with the receiving cavity 110, and the battery can be placed into the receiving cavity 110 through the opening 120.

[0025] like Figure 6 As shown, in some embodiments, the side wall of the box body 100 is provided with heat dissipation holes 130 that communicate with the receiving cavity 110 to facilitate heat dissipation. It is understood that heat dissipation holes 130 can be provided on each side wall of the box body 100, or heat dissipation holes 130 can be provided only on some side walls of the box body 100, and the shapes of the heat dissipation holes 130 can be the same or different.

[0026] Combination Figure 6 and Figure 8 Furthermore, a foot pad 170 is provided on the exterior of the box body 100 at the end away from its opening 120.

[0027] Combination Figure 1 , Figure 4 and Figure 6 The lid 200 is an openable cover located at the box opening 120.

[0028] It is understandable that the cover 200 is placed over the opening 120 of the main body 100 to close the opening 120 and protect the battery placed in the receiving cavity 110. Of course, the cover 200 can be opened to allow the opening 120 to be opened for the battery to be put in and taken out.

[0029] like Figure 1 As shown, in some embodiments, a handle 250 is provided on the side of the lid 200 away from the receiving cavity 110, so that the operator can easily use the handle 250 to open and close the lid 200.

[0030] like Figures 1 to 3As shown, the lock 300 includes a support assembly 310, a locking member 320, and a reset member 330. The support assembly 310 is connected to the outer wall of the body 100 of the box. Specifically, the support assembly 310 is fixed to the outer wall of the body 100 of the box and is located near the opening 120 of the box. The locking member 320 is movably connected to the support assembly 310, that is, the locking member 320 can be operated to move relative to the support assembly 310, and the locking member 320 has a locked state and an unlocked state. In other words, the locking member 320 can move to be in the locked state or the unlocked state. When the locking member 320 is in the locked state, the locking member 320 is used to restrict the movement of the lid 200 relative to the body 100 of the box to fix the lid 200 to the body 100 of the box; when the locking member 320 is in the unlocked state, the locking member 320 avoids the opening path of the lid 200, and the lid 200 can be opened. The reset member 330 is disposed on the support assembly 310 and connected to the locking member 320. The reset member 330 can reset the locking member 320. The reset member 330 is used to make the locking member 320 tend to return to the locked state. Specifically, when the locking member 320 is moved to the unlocked state, the reset member 330 can cause the locking member 320 to reset and be in the locked state.

[0031] When using the battery box of this application, to insert batteries, the locking mechanism 320 can be activated to unlock it. At this time, the lid 200 can be opened, and the batteries can be placed into the receiving cavity 110 through the opening 120 of the main body 100. Then, while keeping the locking mechanism 320 unlocked, the lid 200 is placed over the opening 120 of the main body 100. The reset mechanism 330 then automatically resets the locking mechanism 320 to the locked state, securing the lid 200 to the main body 100. Similarly, to remove batteries, the lid 200 is opened first, and then the batteries are removed. The lock 300 of this application allows for quick locking and unlocking of the lid 200, providing convenient operation without the need for other tools.

[0032] Combination Figure 2 and Figure 3 In some embodiments, the locking member 320 is rotatably connected to the support assembly 310. The locking member 320 has a latching portion 321. When the locking member 320 is in the locked state, the latching portion 321 presses against the side of the lid 200 away from the receiving cavity 110. The locking member 320 can be operably rotated in the unlocking direction to move the latching portion 321 away from the lid 200 and switch to the unlocked state.

[0033] Specifically, the locking member 320 is connected to a rotating shaft 340, and the support assembly 310 has a shaft hole through which the rotating shaft 340 passes. The locking member 320 is rotatably connected to the support assembly 310 by means of the rotating shaft 340. By rotating the locking member 320, the locking member 320 can be in a locked state or an unlocked state. Specifically, the locking member 320 can be operated to rotate relative to the first seat 312 in the unlocking direction to switch from the locked state to the unlocked state, or rotate in the locking direction to switch from the unlocked state to the locked state. When the locking member 320 is in the locked state, the latching part 321 presses against the side of the lid 200 away from the receiving cavity 110 to press the lid 200 tightly onto the body 100, thereby fixing the lid 200. When the locking member 320 is in the unlocked state, the latching part 321 avoids the opening path of the lid 200. At this time, the latching part 321 does not obstruct the opening of the lid 200.

[0034] Combination Figure 2 and Figure 3 In some embodiments, the support assembly 310 includes a support member 311 and a first seat 312 disposed on the support member 311. The support member 311 is connected to the outer wall of the box body 100. Specifically, the support member 311 is fixed to the outer wall of the box body 100 and is disposed near the box opening 120. The first seat 312 is disposed on the support member 311 and supported by the support member 311, and the first seat 312 is fixedly disposed relative to the support member 311. A locking member 320 is rotatably connected to the first seat 312. Specifically, the first seat 312 is provided with a shaft hole, and a rotating shaft 340 passes through the shaft hole so that the locking member 320 is rotatably connected relative to the first seat 312.

[0035] Furthermore, the support assembly 310 also includes a second seat 313, and the locking member 320 also includes a rotating part 322 connected to the fastening part 321. The rotating part 322 is rotatably connected to the first seat 312 via a rotating shaft 340. The fastening part 321 can rotate together with the rotating part 322. The rotating part 322 is located on the side of the box cover 200, and the second seat 313 is located on the side of the rotating part 322 away from the box cover 200. The reset member 330 is an elastic member and is connected between the rotating part 322 and the second seat 313.

[0036] Understandably, when the locking member 320 is in the locked state, the latching part 321 presses against the side of the lid 200 away from the receiving cavity 110 to press the lid 200 tightly onto the body 100, thereby fixing the lid 200. When the locking member 320 rotates in the unlocking direction, the rotating part 322 gradually compresses the reset member 330 to cause the reset member 330 to undergo compression deformation. When the reset member 330 undergoes compression deformation, it applies a reset force to the rotating part 322, so that the locking member 320 tends to return to the locked state. When the locking member 320 is released, the locking member 320 will return to the locked state under the action of the reset member 330.

[0037] In some embodiments, the reset member 330 is a spring; in other embodiments, the reset member 330 may be a sheet or elastic rubber, etc.

[0038] Furthermore, a connecting post 334 is provided on the side of the rotating part 322 facing away from the box cover 200, one end of the reset member 330 is connected to the connecting post 334, and the other end is connected to the second seat 313.

[0039] It should be noted that the locking component 320 also includes a pressing part 323 connected to the rotating part 322. The pressing part 323 can rotate together with the rotating part 322. The pressing part 323 makes it easy for the operator to operate the locking component 320 by hand so that the locking component 320 can rotate.

[0040] Combination Figure 2 and Figure 3 In some embodiments, the lock 300 further includes a stop 350, which is disposed on the support assembly 310 and engages with the latch 320. The stop 350 is used to restrict the movement of the latch 320 in the unlocking direction when it is in the latched state, and the latch 320 can be operably separated from the latch 320 so that the latch 320 can move in the unlocking direction.

[0041] Understandably, the stop 350 can stop the latch 320, and the stop 350 can also separate from the latch 320 to allow the latch 320 to move. When it is necessary to keep the lock 300 latching the lid 200, the stop 350 stops the latch 320, thus reducing the risk of the latch 320 moving in the unlocking direction due to accidental operation and improving reliability. When it is necessary to open the lid 200, the stop 350 can be separated from the latch 320 first, and then the latch 320 can be moved in the unlocking direction.

[0042] When using the battery box of this application, to insert batteries, the stop 350 can be disengaged from the locking member 320 first. Then, the locking member 320 can be moved to the unlocked state. At this time, the cover 200 can be opened, and the batteries can be placed into the receiving cavity 110 through the opening 120 of the main body 100. Afterwards, while keeping the locking member 320 in the unlocked state, the cover 200 is placed over the opening 120 of the main body 100. Then, the reset member 330 can automatically drive the locking member 320 to reset and enter the locked state to fix the cover 200 to the main body 100. Then, the stop 350 is operated to hold the locking member 320 to stop it. It can be understood that when it is necessary to remove the batteries from the battery box, the cover 200 can be opened first in the above manner, and then the batteries can be removed.

[0043] Specifically, the stop 350 is movably disposed on the support assembly 310 and located on the side of the rotating part 322 away from the cover 200. The stop 350 can be operated to move closer to or away from the rotating part 322. When the latch 320 is in the latched state, the stop 350 can restrict the movement of the latch 320 in the unlocking direction when it abuts against the rotating part 322. When the stop 350 is operated away from the rotating part 322 and separated from the rotating part 322, the stop 350 releases its restrictive effect on the latch 320, at which time the latch 320 can move in the unlocking direction.

[0044] More specifically, the stop 350 is threadedly connected to the support assembly 310 and can be operably moved closer to or away from the rotating part 322. Specifically, the stop 350 is threadedly connected to the second seat 313. More specifically, the second seat 313 has a first mounting hole, which is opposite to the rotating part 322. The stop 350 passes through the first mounting hole and can be operably moved closer to or away from the rotating part 322. The first mounting hole can be a threaded hole, and the stop 350 has a threaded section that passes through the threaded hole, and the two are threadedly connected. It should be noted that a knob is provided at the end of the stop 350 away from the second seat 313. The stop 350 can be manually rotated by the knob to move closer to or away from the rotating part 322 without the need for other tools.

[0045] In some embodiments, when the stop 350 abuts against the surface of the rotating part 322, the stop 350 can restrict the movement of the locking member 320 in the unlocking direction; in other embodiments, a second mounting hole can be provided on the rotating part 322. When the locking member 320 is in the locking state, the first mounting hole and the second mounting hole are arranged opposite to each other. Both the first mounting hole and the second mounting hole are threaded holes, and the threaded section of the stop 350 can pass through the first mounting hole and the second mounting hole simultaneously.

[0046] Combination Figure 4 and Figure 5 In some embodiments, the cover 200 is provided with a first mounting hole, the body 100 is provided with a second mounting hole 180 corresponding to the first mounting hole, and the battery box also includes an elastic abutment 400, which passes through the first mounting hole and the second mounting hole and abuts against the hole wall of the second mounting hole 180 to reduce the risk of the cover 200 becoming loose.

[0047] Specifically, one end of the elastic abutment 400 has a limiting head 410, and the outer surface of the other end is provided with elastic rubber. The elastic rubber passes through the second mounting hole 180 and abuts against the wall of the second mounting hole 180, and the limiting head 410 abuts against the edge of the end of the first mounting hole away from the second mounting hole 180. It should be noted that the elastic abutment 400 can be installed and removed by relevant personnel simply by inserting and removing it, without the need for tools.

[0048] More specifically, the four corners of the lid 200 are further connected to the body 100 of the box via elastic abutment members 400.

[0049] like Figure 6 As shown, in some embodiments, a first limiting frame 140 is provided in the receiving cavity 110. The first limiting frame 140 is provided with a plurality of first limiting grooves 143 arranged in parallel. The openings of the plurality of first limiting grooves 143 are all set facing the box opening 120. Each first limiting groove 143 can accommodate a battery. The first limiting groove 143 can limit the battery and reduce the risk of battery shaking.

[0050] Specifically, the first limiting frame 140 includes a first outer frame 141 connected to the inner wall of the box body 100, and a plurality of first partition plates 142 disposed in the first outer frame 141. The plurality of first partition plates 142 are arranged side by side and spaced apart, so that a plurality of first limiting grooves 143 can be formed in the first outer frame 141.

[0051] Combination Figure 6 and Figure 7 Furthermore, the case cover 200 includes a case cover body 210 and a second limiting frame 220 disposed inside the case cover body 210. The second limiting frame 220 has a plurality of second limiting grooves 223 arranged in parallel, and the plurality of second limiting grooves 223 are arranged opposite to the plurality of first limiting grooves 143 in a one-to-one correspondence. Specifically, the openings of the plurality of second limiting grooves 223 are arranged opposite to the openings of the plurality of first limiting grooves 143 in a one-to-one correspondence. In this way, when one end of the plurality of batteries is respectively placed into the plurality of first limiting grooves 143, after the case cover 200 is closed, the other ends of the plurality of batteries are respectively inserted into the plurality of second limiting grooves 223. This can further improve the anti-shake capability of the batteries.

[0052] Specifically, the second limiting frame 220 includes a second outer frame 221 connected to the inner side wall of the box cover body 210, and a plurality of second partition plates 222 disposed in the second outer frame 221. The plurality of second partition plates 222 are arranged side by side and spaced apart, so that a plurality of second limiting grooves 223 can be formed in the second outer frame 221.

[0053] Combination Figure 6 and Figure 7 In some embodiments, the battery box further includes a first buffer pad 150 and a second buffer pad 240. The first buffer pad 150 is disposed within the receiving cavity 110, and the second buffer pad 240 is disposed inside the box cover 200. The first buffer pad 150 and the second buffer pad 240 are spaced apart and disposed opposite to each other. When the battery is placed in the receiving cavity 110 and the box cover 200 is closed on the box body 100, the battery is held between the first buffer pad 150 and the second buffer pad 240. The first buffer pad 150 and the second buffer pad 240 can protect the battery and reduce the risk of battery damage.

[0054] The first buffer pad 150 and / or the second buffer pad 240 can be an elastic rubber pad or a honeycomb buffer plate.

[0055] like Figure 5 As shown, in some embodiments, the lid 200 further includes a positioning part 230 connected to the inner side wall of the lid body 210. The lid body 100 is provided with a positioning groove 160 on the side near the lid opening 120. The positioning part 230 is inserted into the positioning groove 160. In this way, the positioning effect between the lid 200 and the lid body 100 can be improved.

[0056] Specifically, the positioning groove 160 is arranged around the box opening 120, and the positioning part 230 is adapted to the shape of the positioning groove 160. When the positioning part 230 is inserted into the positioning groove 160, it can also improve the sealing between the box cover 200 and the box body 100.
