[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1: Please refer to Figure 1-Figure 8 The present invention provides a technical solution: an anti-collision type self-cooling outdoor lithium battery box, comprising: an anti-collision shell 1, a sealing cover 2 is arranged on the top of the anti-collision shell 1, and a built-in lithium battery body 3 and a protective solution are arranged between the anti-collision shell 1 and the sealing cover 2; a spacing is reserved between the bottom of the built-in lithium battery body 3 and the inner wall of the bottom of the anti-collision shell 1, and the protective solution inside the anti-collision shell 1 gives the built-in lithium battery body 3 a buoyancy thrust; the use of the above technical solution makes the bottom of the built-in lithium battery body 3 suspended, and the buoyancy thrust is given by the protective solution, and the connector 4 installed on the top of the built-in lithium battery body 3 achieves a positioning effect. When the anti-collision shell 1 collides with the edge and the bottom, the kinetic energy directly applied to the built-in lithium battery body 3 by the collision external force and the vibration external force is reduced, so that the first step achieves the effect of the built-in lithium battery body 3, and the kinetic energy is conducted by the protective solution to absorb and release the kinetic energy.

[0022] The protective solution includes but is not limited to the coolant in the conventional immersion battery cooling system, and lithium ion compounds such as lithium bis(trifluoromethanesulfonyl imide); non-aqueous solutions such as mineral oil, silicone oil, natural esters, etc.; it uses the effect of liquid to drive the working temperature of the lithium battery to achieve a cooling effect, and at the same time uses the liquid to reduce shock and release energy during external force collision or use of the lithium battery.

[0023] It also includes: a connector 4, the lower end of which is connected to the top of the built-in lithium battery body 3, wherein the upper end surface of the connector 4 and the magnetic positioning plate 6 embedded in the middle of the sealing cover 2 are in a fitted magnetic sliding connection, and at the same time, elastic telescopic rods 5 are horizontally and evenly distributed between the upper end of the connector 4 and the bottom surface of the sealing cover 2; the highest liquid level of the protective solution is located below the middle section of the connector 4, and the protective solution is used for cooling and buffering the energy release protection of the built-in lithium battery body 3; a limiting ring body 501 is provided at the connection between the sealing cover 2 and the elastic telescopic rod 5; the limiting ring body 501 and the tail end of the elastic telescopic rod 5 are horizontally hinged and rotatably arranged, wherein the head end of the elastic telescopic rod 5 and the connector 4 are horizontally hinged; the connector 4 is arranged in an "I"-shaped structure, wherein the horizontal plane where the evenly distributed elastic telescopic rods 5 are located is perpendicular to the connector 4, and the horizontal plane where the elastic telescopic rods 5 are located is located above the horizontal plane where the middle section of the connector 4 is located.

[0024] In the above technical scheme, when an external force collides with the anti-collision shell 1, the power of the collision releases energy through the protective solution, and at the same time causes the protective solution to move. During this movement, since the built-in lithium battery body 3 is located below the liquid surface, the movement amplitude of the liquid surface is large, and the force acting on the built-in lithium battery body 3 is reduced. Under the action of the collision, the built-in lithium battery body 3 is also subjected to external force, and the rotational installation and telescopic movement of the elastic telescopic rod 5 can reset the built-in lithium battery body 3 under the action of external force. In this process, kinetic energy is released, reducing the destructiveness of the internal electrical components of the built-in lithium battery body 3 caused by the kinetic energy, and achieving the anti-collision protection effect of the built-in lithium battery body 3.

[0025] At the same time, using Figure 1 and Figure 6 As shown, in the present technical solution, a gas pressurizing assembly 10 is also fixed to the top of the sealing cover 2, wherein an air guide pipe 11 is also provided on the front side of the anti-collision shell 1, the air inlet of the air guide pipe 11 is connected to the gas pipeline of the gas pressurizing assembly 10, and the air outlet of the air guide pipe 11 is located at the bottom inner side of the anti-collision shell 1; at the same time, a first valve body 12 is provided at the connection between the air inlet of the air guide pipe 11 and the gas pipeline of the gas pressurizing assembly 10; a second valve body 13 is also fixed to the side of the top of the sealing cover 2 away from the gas pressurizing assembly 10, and an electrical interface and a protective cover body thereof are also provided on the top of the sealing cover 2.

[0026] By setting up the gas pressurizing component 10, when the lithium battery box is in use, the first valve body 12 and the second valve body 13 can be opened synchronously by electronic control, and the gas pressurizing component 10 is used to drive the airflow. The airflow can cool the built-in lithium battery body 3 through the protective solution, thereby achieving the cooling protection effect of the built-in lithium battery body 3. At the same time, when the protective solution reciprocates and impacts the built-in lithium battery body 3 and the inner wall of the anti-collision shell 1 under the action of collision, the airflow makes the regular movement trend of the protective solution disordered, thereby reducing the impact kinetic energy of the built-in lithium battery body 3 and the anti-collision shell 1 caused by the movement of the protective solution, thereby achieving further protection effect of the lithium battery box.

[0027] Also adopt Figure 7 and Figure 8 As shown, a folding rod 14 and a folding wheel set 15 are also installed on the back of the anti-collision shell 1, and the folding rod 14 and the folding wheel set 15 are used for the portable movement of the lithium battery box; the folding rod 14 and the folding wheel set 15 are limited by bolts after being folded; the folding and unfolding of the folding rod 14 and the folding wheel set 15 facilitate the transportation and movement of the lithium battery box.

[0028] Embodiment 2: The present invention adopts Figure 9-11 As shown, it is further disclosed that a limit ring body 501 is provided at the connection between the sealing cover 2 and the elastic telescopic rod 5; the end of the elastic telescopic rod 5 is hingedly rotated with a rotating member 502 on the limit ring body 501, and the rotating member 502 is rotationally connected to the limit ring body 501; and the head end of the elastic telescopic rod 5 is connected to the elastic member 503 on the connecting member 4; the vertical rotation direction of the rotating member 502 and the limit ring body 501 and the lateral rotation direction of the elastic telescopic rod 5 and the rotating member 502 are perpendicular to each other; wherein the rotating member 502 and the limit ring body 501 are rotationally connected by a rotating shaft; and the elastic member 503 is used for multi-directional rotation adjustment of the connection between the head end of the elastic telescopic rod 5 and the connecting member 4; In the above technical scheme, this scheme is set up on the basis of embodiment one, so that when the lithium battery box is hit by external force, the built-in lithium battery body 3 can not only move in the horizontal direction, but also make the elastic telescopic rod 5 extend and rotate in the horizontal direction to achieve the effect of kinetic energy release; through the action of the rotating member 502 and the elastic member 503, the elastic telescopic rod 5 can adjust the rotation angle in the vertical direction when extending and rotating in the horizontal direction, so that the built-in lithium battery body 3 can swing during the collision, thereby improving the efficiency of kinetic energy release. Under this action, when the lithium battery box is hit by the top, the built-in lithium battery body 3 can also release kinetic energy to achieve the effect of anti-collision protection.

[0029] In the above solution, the elastic member 503 may be provided with an elastic liquid bag or other components capable of rotating in multiple directions to release energy.

[0030] At the same time, an anti-collision component is provided at the bottom of the built-in lithium battery body 3, and the magnetic positioning plate 6 is penetrated through the middle of the anti-collision shell 1, and an elastic sealing belt is provided at the penetration point; and a top cover 7 is also fixed on the top of the anti-collision shell 1 just above the magnetic positioning plate 6, and an electromagnet 8 and a reset spring 9 are fixed inside the top cover 7, the bottom of the reset spring 9 is connected to the top edge of the magnetic positioning plate 6, and an active gap is reserved between the bottom surface of the electromagnet 8 and the magnetic positioning plate 6; the anti-collision component includes elastic plastic, spring and other objects with buffering function, which are used for anti-collision during the vertical movement and energy release of the built-in lithium battery body 3, and protecting the bottom when the built-in lithium battery body 3 swings. At the same time, the reset spring 9 controls and resets the magnetic positioning plate 6 when the built-in lithium battery body 3 swings, so that the built-in lithium battery body 3 and the connector 4 and the magnetic positioning plate 6 have the conditions and space for swinging, and the setting of the sealing belt enables the magnetic positioning plate 6 to have space for movement without causing liquid leakage.

[0031] Furthermore, a sensor element is also provided on the connector 4, which can monitor the swing amplitude of the built-in lithium battery body 3. When the external force of the lithium battery box is too large and the collision force is too large to exceed the monitoring threshold of the sensor element, resulting in excessive movement of the built-in lithium battery body 3, which may easily cause overload damage to the built-in lithium battery body 3, the sensor element controls the start-up of the electromagnet 8 through the integrated circuit in which it is located, so that the electromagnet 8 magnetically positions the magnetic positioning plate 6, and the magnetic positioning plate 6 remains relatively still. At this time, the built-in lithium battery body 3 can only move and release energy in the horizontal direction, thereby achieving the protection effect of the built-in lithium battery body 3 and its supporting mounting components.

[0032] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
