[0027] The following describes the preferred embodiments of the present utility model with reference to the drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present utility model and are not used to limit the present utility model.

[0028] Combined with Figures 1 to 5 As shown, according to an embodiment of the present application, a mobile integrated device for external power discharge of a new energy vehicle is provided, which includes an inner shell 1. A protection box is arranged inside the inner shell 1. The protection box includes a box body 301 and a box cover 302. A partition member is arranged inside the box body 301. The partition member is used to divide at least two placement spaces in the protection box. The placement spaces are used to place batteries. The partition member includes at least two parallel mica sheets 303. An aerogel heat insulation layer 304 is arranged between adjacent mica sheets 303. A locking member is arranged on the protection box. The locking member is used to lock or unlock the box body 301 and the box cover 302. A sealing member 4 is arranged on the box cover 302. When the box body 301 and the box cover 302 are locked, the sealing member 4 is pressed between the box body 301 and the box cover 302.

[0029] By setting a partition in the box body 301, and separating at least two placement spaces for placing batteries in the protective box through the partition, a placement position is provided for the battery. By setting at least two parallel mica sheets 303, and setting an aerogel insulation layer 304 between adjacent mica sheets 303, the heat transfer between the batteries can be effectively blocked. When the battery has thermal runaway, the heat can be prevented from spreading rapidly to the entire module, avoiding a chain reaction, buying more time for the user's escape and rescue, and also protecting the normal operation of other batteries, extending the service life of the battery. By setting a seal 4 in the protective box, when the box body 301 and the box cover 302 are locked, the seal 4 is pressed between the two, which can effectively improve the waterproof and dustproof performance of the device. It can reduce the entry of external moisture and dust into the device, reduce the risk of short circuit, leakage, fire and explosion, and ensure safety during use.

[0030] The protective box may be a hollow cubic structure. The box body 301 is the main body, and has a box opening on the top. The box cover 302 is disposed on the box opening to close the box opening, so that a closed space is formed inside the protective box.

[0031] The height of the partition is the same as the height of the inner space of the protective box, that is, the top of the partition is in conflict with the box cover 302, thereby forming at least two mutually isolated placement spaces.

[0032] Specifically, there is one partition, which is arranged along a symmetric plane of the protection box, thereby separating two identical placement spaces in the protection box.

[0033] Specifically, the separator is a flat plate structure, and includes two mica sheets 303 arranged in parallel, with an aerogel insulation layer 304 sandwiched between the two mica sheets 303 .

[0034] The locking member is disposed on the outer wall of the box body 301 , and the box body 301 and the box cover 302 can be locked or unlocked by the locking member.

[0035] Specifically, the seal 4 is a sealing ring, which is arranged along the edge of the box cover 302. The edge of the box cover 302 is used to cover the edge of the box opening, so that when the box body 301 and the box cover 302 are locked, the seal 4 is pressed between the box body 301 and the box cover 302.

[0036] An accommodating cavity is arranged in the inner shell 1, and the protection box is arranged in the accommodating cavity. A shock-absorbing rubber pad 305 is arranged on the bottom outer wall of the protection box.

[0037] By arranging the protective box inside the accommodating cavity, the direct impact and interference of external factors on the protective box can be reduced, which helps to maintain a stable operating environment for components such as the battery inside the protective box, and further reduces the risks of short circuit, electric leakage, and fire and explosion. By arranging shock-absorbing rubber pads 305 on the outer wall of the bottom of the protective box, the vibration and impact received during the movement and transportation of the device can be effectively buffered, preventing the batteries inside the protective box from colliding with each other and shifting due to vibration, protecting the internal structure of the batteries from damage, thus prolonging the service life of the batteries, ensuring the stability of battery performance, and enhancing the stability and safety of the external power discharge of the entire device.

[0038] Among them, the shape of the shock-absorbing rubber pad 305 is adapted to the shape of the outer wall of the bottom of the protective box.

[0039] Specifically, the protective box is generally a cube structure, the bottom surface of the protective box is a square, the shock-absorbing rubber pad 305 is a cube or cuboid structure, and the top surface has the same shape and size as the bottom surface of the protective box.

[0040] Specifically, the shock-absorbing rubber pad 305 can be rubber with certain elasticity.

[0041] The locking member includes a locking hook 501, a fixed seat 502, a buckle 503 and a handle 504. The locking hook 501 is arranged on the outer wall of the box cover 302, the fixed seat 502 is arranged on the outer wall of the box body 301, the handle 504 is rotatably connected to the fixed seat 502, the buckle 503 is arranged on the handle 504, and the buckle 503 is used for hooking on the locking hook 501. The handle 504 can rotate on the fixed seat 502 in a direction away from the locking hook 501 to lock the locking hook 501 and the buckle 503, or rotate in a direction close to the locking hook 501 to unlock the locking hook 501 and the buckle 503.

[0042] By making the handle 504, the buckle 503, the locking hook 501 and the fixed seat 502 cooperate with each other, in the locked state, a stable connection structure can be formed to ensure the tight combination of the box body 301 and the box cover 302. Even when the device is moving or being vibrated, a good closed state can be maintained, ensuring the waterproof and dustproof performance of the protective box, further reducing the risks of short circuit, electric leakage, and fire and explosion, and protecting the safety of the internal battery and other components. By arranging the handle 504 rotatably connected to the fixed seat 502, cooperating with the buckle 503 arranged on the handle 504 and the locking hook 501 on the box cover 302, the locking and unlocking operations of the box body 301 and the box cover 302 are completed by rotating the handle 504.

[0043] The locking hook 501 and the fixing seat 502 are arranged opposite to each other in the vertical direction. The tip of the locking hook 501 extends upward, that is, the opening of the locking hook 501 is upward, the fixing seat 502 is arranged below the locking hook 501, and the handle 504 is rotated vertically on the fixing seat 502, so that the buckle 503 can be close to or away from the locking hook 501 in the vertical direction.

[0044] The buckle 503 is ring-shaped and is rotatably disposed on the handle 504 .

[0045] Specifically, when locking, the handle 504 is turned upward, so that the buckle 503 approaches the locking hook 501 and moves above the locking hook 501, and the buckle 503 enters the locking hook 501 from top to bottom. The handle 504 is turned downward, so that the buckle 503 moves downward in the locking hook 501, and is then limited and fixed in the locking hook 501. When unlocking, the handle 504 is turned upward, so that the buckle 503 moves upward, and can be released from the locking hook 501 from above, thereby achieving unlocking.

[0046] An elastic member is disposed between the buckle 503 and the handle 504 .

[0047] The elastic force provided by the elastic member can make the buckle 503 hook more tightly on the locking hook 501, so as to achieve a firm lock between the buckle 503 and the locking hook 501. When the device is subjected to vibration and bumps, the elastic member can buffer the external force caused by the shaking, and prevent the buckle 503 from accidentally detaching from the locking hook 501, so as to ensure that the box body 301 and the box cover 302 are always locked, maintain the good sealing of the protective box, protect the internal battery and other components from being affected by the external environment, and reduce the risk of short circuit, leakage, fire and explosion.

[0048] The buckle 503 is connected to the handle 504 via an elastic member.

[0049] Specifically, the elastic member may be a spring.

[0050] The protection box is provided with a rotating connection piece, through which the box body 301 and the box cover 302 are hinged, and the rotating connection piece is provided on a side of the protection box away from the locking piece.

[0051] By providing a rotating connection, the box body 301 and the box cover 302 can rotate relative to each other, and the opening and closing operation is smoother and more convenient. In addition, the rotating connection can also provide stable rotation support. When opening and closing the box cover 302, the movement track of the box cover 302 is fixed, and it is not easy to shake or deviate, which is convenient for users to operate. For example, when it is necessary to replace or maintain the battery in the protective box, the user can easily open the box cover 302, and the box cover 302 can be stably maintained in the open state after opening, which is convenient for users to perform related operations.

[0052] The rotating connecting member is arranged on the side away from the locking member, so that the locking member can play a better role when locking, and ensure the sealing effect between the box body 301 and the box cover 302. When the locking member locks the box body 301 and the box cover 302, since the rotating connecting member and the locking member are distributed on opposite sides, the box body 301 and the box cover 302 can be more evenly stressed on the entire periphery, thereby ensuring that the sealing member 4 is fully pressed between the box body 301 and the box cover 302, effectively blocking the entry of external water and dust into the protection box, and reducing risks such as short circuit, electric leakage, and fire and explosion caused by water ingress or dust accumulation, improving the safety and reliability of the device.

[0053] The rotating connecting member includes a rotating shaft 306 and two rotating seats 307. The two rotating seats 307 are fixedly arranged on the box body 301. One end of the rotating shaft 306 is rotatably arranged in one rotating seat 307, and the other end of the rotating shaft 306 is rotatably arranged in the other rotating seat 307. A convex block 308 is arranged on the outer peripheral wall of the rotating shaft 306, and the convex block 308 is connected to the box cover 302.

[0054] The two rotating seats 307 are fixed on the box body 301, and both ends of the rotating shaft 306 are rotatably arranged in the two rotating seats 307 respectively, providing stable support for the rotating shaft 306 and enabling the rotating shaft 306 to rotate smoothly. When the box cover 302 rotates around the rotating shaft 306, it can ensure a smooth rotation process and avoid jamming or shaking, improving the convenience of opening and closing the box cover 302 and facilitating operations such as installing and maintaining the battery in the protection box for users.

[0055] The convex block 308 arranged on the outer peripheral wall of the rotating shaft 306 is connected to the box cover 302, which can firmly connect the box cover 302 and the rotating shaft 306 together and prevent the box cover 302 from detaching from the rotating shaft 306 during rotation. At the same time, since the rotating seat 307 is fixedly connected to the box body 301, the entire rotating connecting member and the box body 301 and the box cover 302 form a stable overall structure. Even when the device is subjected to external forces such as vibration and collision, the connection between the box cover 302 and the box body 301 can be ensured to be stable, maintaining the normal use function of the protection box and ensuring the safety of internal components such as the battery.

[0056] Among them, the two rotating seats 307 are arranged opposite to each other in the horizontal direction.

[0057] Specifically, the rotating seat 307 has a hollow structure and one end is open, and the end of the rotating shaft 306 is inserted into the rotating seat 307 from the open end.

[0058] Among them, the rotating shaft 306 is of a cylindrical structure and is horizontally arranged.

The buffer spring 202 is in contact with the outer wall of the bottom of the box body 301.

[0060] The damper 201 and the buffer spring 202 are arranged in the installation groove of the bottom plate 2. Through the combined action of the damper 201 and the buffer spring 202, double shock absorption protection is provided for the box body 301. When the device is vibrated or impacted, the damper 201 can effectively consume the vibration energy and slow down the vibration transmission. The buffer spring 202 further absorbs the remaining impact force, greatly reducing the impact of vibration on the battery in the box body 301, being able to avoid damage to the battery due to vibration, extending the service life of the battery, ensuring the stable performance of the battery, and thus improving the reliability of the whole device for external power discharge.

[0061] The bottom of the box body 301 is placed in the installation groove. The installation groove plays a role in positioning and limiting the box body 301, preventing the box body 301 from shaking and displacing randomly during the movement of the device, making the overall structure of the device more stable. It is beneficial to the normal use of the device, and can also avoid problems such as loose connection of internal circuits caused by the shaking of the box body 301, reducing the possibility of faults.

[0062] Among them, the bottom plate 2 is arranged at the bottom of the box body 301. The installation groove on the bottom plate 2 is recessed downward. The bottom of the box body 301 enters the installation groove from top to bottom and is in contact with the buffer spring 202.

[0063] Among them, the bottom plate 2 is detachably connected to the box body 301, for example, by screw connection.
