[0014] The method for using the high-protection energy storage battery module includes the following steps:

[0015] S1: Installing batteries, first placing several battery modules on the push-pull plate, when several battery modules are placed inside the push-pull plate, start the electric telescopic rod, the end of the electric telescopic rod away from the connecting plate 1 drives the side guard plate on the connecting plate 2 to move, and the side guard plate drives several push-pull plates to slide along the sliding groove at the bottom of the protective shell into the protective shell;

[0016] S2: Initial heat dissipation, the push-pull plate drives the bottom lifting plate to slide into the protective housing. When the lifting plate contacts and squeezes the wedge-shaped squeezing block, the lifting plate is squeezed by the wedge-shaped squeezing block and rotates upward along the rotating rod. At this time, the lifting plate drives several battery modules above the lifting plate to move upward;

[0017] S3: Fixed heat dissipation, the sliding column drives the pressure spring at one end of the linkage telescopic rod to move toward the side wall of the battery module, and the pressure spring drives the heat sink to slide toward the side wall of the battery module. This arrangement is conducive to the heat sink fixing the battery module to prevent the battery module from shaking. In addition, the heat sink is close to the side wall of the battery module, which is conducive to enhancing the heat dissipation effect of the heat sink on the battery module;

[0018] S4: Stable output, lifting the heat dissipation mechanism drives the negative electrode and the positive electrode of the battery directly above the battery module to squeeze the negative electrode connecting plate and the positive electrode connecting plate upward. At this time, the negative electrode connecting plate squeezes the negative electrode squeezing spring upward, so that the contraction elastic force of the negative electrode squeezing spring increases, and the positive electrode connecting plate squeezes the positive electrode squeezing spring upward, and the contraction elastic force of the positive electrode squeezing spring increases. This setting is conducive to increasing the connection strength of several output endpoints.

[0019] The present invention has the following beneficial effects:

[0020] (1) The present invention provides a lifting and heat dissipation mechanism. When one end of the electric telescopic rod is away from the connecting plate one, it drives the side guard plate on the connecting plate two to move. The side guard plate drives a plurality of push-pull plates to slide along the sliding groove at the bottom of the protective shell toward the inside of the protective shell. The push-pull plate drives the lifting plate at the bottom to slide toward the inside of the protective shell. When the lifting plate contacts and squeezes the wedge-shaped squeezing block, the lifting plate is squeezed by the wedge-shaped squeezing block and rotates upward along the rotating rod. At this time, the lifting plate drives a plurality of battery modules above the lifting plate to move upward. This arrangement is beneficial to increasing the space between the bottom of the plurality of battery modules and the inner wall of the bottom of the protective shell on the one hand, and reducing the air intake resistance of the air intake slot on the other hand, increasing the air intake volume of the air intake slot, thereby enhancing the heat dissipation effect at the bottom of the battery module.

[0021] (2) According to the present invention, when using the high-protection energy storage battery module, a plurality of battery modules are first placed on a push-pull plate. When the plurality of battery modules are placed inside the push-pull plate, the electric telescopic rod is started. The end of the electric telescopic rod away from the connecting plate one drives the side guard plate on the connecting plate two to move. The side guard plate drives the plurality of push-pull plates to slide along the sliding groove at the bottom of the protective shell toward the inside of the protective shell. By setting up a push-pull mechanism, it is convenient to place the plurality of battery modules into the inside of the protective shell for protection. When it is necessary to inspect the plurality of battery modules inside, it is only necessary to start the electric telescopic rod. The electric telescopic rod drives the plurality of battery modules on the push-pull plate to extend out of the inside of the protective shell. This arrangement facilitates the inspection of the plurality of battery modules inside the protective shell.

[0022] (3) The present invention provides a pushing and squeezing mechanism. When one end of the electric telescopic rod moves away from the connecting plate one, it drives the side guard plate on the connecting plate two to move. The movement of the side guard plate drives the sliding sleeve at one end of the reset spring to slide along the sliding rod. When the sliding sleeve slides to the limit block on the sliding rod, the limit block squeezes the sliding sleeve to cause the reset spring to contract. At this time, the sliding sleeve drives the sliding column on the push-pull plate to slide inward along the push-pull plate. The sliding column drives the pressure spring at one end of the linked telescopic rod to move toward the side wall of the battery module. The pressure spring drives the heat sink to slide toward the side wall of the battery module. When the linked telescopic rod contracts, the pressure spring contracts. At this time, the elastic force of the pressure spring increases, and the squeezing force of the pressure spring on the heat sink on the pressure spring increases. This arrangement is conducive to fixing the battery module with the heat sink and preventing the battery module from shaking. In addition, the heat sink is close to the side wall of the battery module, which is conducive to enhancing the heat dissipation effect of the heat sink on the battery module.

[0023] (4) The present invention sets an output fixing mechanism. When the lifting plate contacts and squeezes the wedge-shaped squeezing block, the lifting plate is squeezed by the wedge-shaped squeezing block and rotates upward along the rotating rod. At this time, the lifting plate drives several battery modules above the lifting plate to move upward. The battery modules drive the negative and positive electrodes of the batteries above to squeeze the negative connecting plate and the positive connecting plate upward. At this time, the negative connecting plate squeezes the negative squeezing spring upward, so that the contraction elastic force of the negative squeezing spring increases. The positive connecting plate squeezes the positive squeezing spring upward, and the contraction elastic force of the positive squeezing spring increases. Such a setting is conducive to increasing the connection strength of several output terminals, avoiding the phenomenon of virtual connection between the negative and positive electrodes of the batteries on the battery module, thereby enhancing the working stability of the device.

By setting the push-pull mechanism 2, it is convenient to put several battery modules 205 into the protective shell 1 for protection. When it is necessary to check the several battery modules 205 inside, it is only necessary to start the electric telescopic rod 13, and the electric telescopic rod 13 drives several battery modules 205 on the push-pull plate 202 to extend out of the protective shell 1.

On the other hand, it reduces the wind resistance of the air intake groove 301 and increases the air intake volume of the air intake groove 301, thereby enhancing the heat dissipation effect at the bottom of the battery module 205.

[0044] Embodiment 2 is different from Embodiment 1 in that: Figure 1-Figure 11 As shown, a pushing and squeezing mechanism 4 is arranged inside the protective shell 1, and the pushing and squeezing mechanism 4 includes a plurality of return springs 401 fixedly connected to the side guard plate 203 close to the push-pull plate 202.

This arrangement is conducive to fixing the battery module 205 with the heat sink 405 to prevent the battery module 205 from shaking. In addition, the heat sink 405 is close to the side wall of the battery module 205, which is conducive to enhancing the heat dissipation effect of the heat sink 405 on the battery module 205.

At this time, the lifting plate 304 drives several battery modules 205 above the lifting plate 304 to move upward. The battery module 205 drives the battery negative electrode 501 and the battery positive electrode 502 directly above to squeeze the negative electrode connecting plate 504 and the positive electrode connecting plate 506 upward. At this time, the negative electrode connecting plate 504 squeezes the negative electrode squeezing spring 503 upward, so that the contraction elastic force of the negative electrode squeezing spring 503 increases, and the positive electrode connecting plate 506 squeezes the positive electrode squeezing spring 505 upward, and the contraction elastic force of the positive electrode squeezing spring 505 increases.

This arrangement is conducive to the heat sink 405 fixing the battery module 205 to prevent the battery module 205 from shaking. In addition, the heat sink 405 is close to the side wall of the battery module 205, which is conducive to enhancing the heat dissipation effect of the heat sink 405 on the battery module 205;

[0052] S4: Stabilize the output, lift the heat dissipation mechanism 3 to drive the battery negative electrode 501 and the battery positive electrode 502 directly above the battery module 205 to squeeze the negative electrode connecting plate 504 and the positive electrode connecting plate 506 upward.

This arrangement is beneficial to increase the connection strength of several output endpoints.

[0053] A specific application of this embodiment is:

[0054] When using the high-protection energy storage battery module, first place a number of battery modules 205 on the push-pull plate 202. When the battery modules 205 are placed inside the push-pull plate 202, start the electric telescopic rod 13. The end of the electric telescopic rod 13 away from the connecting plate 12 drives the side guard plate 203 on the connecting plate 204 to move. The side guard plate 203 drives the push-pull plates 202 to slide along the sliding groove 201 at the bottom of the protective shell 1 to the inside of the protective shell 1. By setting the push-pull mechanism 2, it is convenient to put a number of battery modules 205 into the protective shell 1 for protection. When it is necessary to inspect the battery modules 205 inside, it is only necessary to start the electric telescopic rod 13. The electric telescopic rod 13 drives the battery modules 205 on the push-pull plate 202 to extend out of the protective shell 1. This arrangement facilitates the inspection of the battery modules 205 inside the protective shell 1. When the end of the electric telescopic rod 13 away from the connecting plate 1 12 drives the side guard plate 203 on the connecting plate 2 204 to move, the side guard plate 203 drives a plurality of push-pull plates 202 to slide along the sliding groove 201 at the bottom of the protective shell 1 into the inside of the protective shell 1, and the push-pull plate 202 drives the bottom lifting plate 304 to slide into the inside of the protective shell 1. When the lifting plate 304 contacts and squeezes the wedge-shaped squeezing block 302, the lifting plate 304 is squeezed by the wedge-shaped squeezing block 302 and rotates upward along the rotating rod 303. At this time, the lifting plate 304 drives a plurality of battery modules 205 above the lifting plate 304 to move upward. This arrangement is conducive to increasing the space between the bottom of the plurality of battery modules 205 and the inner wall of the bottom of the protective shell 1 on the one hand, and reducing the wind resistance of the air inlet slot 301 on the other hand, increasing the air intake volume of the air inlet slot 301, thereby enhancing the heat dissipation effect at the bottom of the battery module 205.

[0055] By setting the pushing and squeezing mechanism 4, when the end of the electric telescopic rod 13 away from the connecting plate 1 12 drives the side guard plate 203 on the connecting plate 2 204 to move, the movement of the side guard plate 203 drives the sliding sleeve 404 at one end of the return spring 401 to slide along the slide rod 402, and when the sliding sleeve 404 slides to the limit block 403 on the slide rod 402, the limit block 403 squeezes the sliding sleeve 404 so that the return spring 401 contracts. At this time, the sliding sleeve 404 drives the sliding column 407 on the push-pull plate 202 to move inward along the push-pull plate 202. The sliding column 407 drives the pressure spring 409 at one end of the linkage telescopic rod 408 to move toward the side wall of the battery module 205, and the pressure spring 409 drives the heat sink 405 to slide toward the side wall of the battery module 205. When the linkage telescopic rod 408 contracts, the pressure spring 409 contracts. At this time, the elastic force of the pressure spring 409 increases, and the squeezing force of the pressure spring 409 on the heat sink 405 on the pressure spring 409 increases. This arrangement is conducive to fixing the heat sink 405 to the battery module 205 and preventing the battery module 205 from shaking. The heat sink 405 is in close contact with the side wall of the battery module 205, which is conducive to enhancing the heat dissipation effect of the heat sink 405 on the battery module 205; by setting the output fixing mechanism 5, when the lifting plate 304 contacts and squeezes the wedge-shaped squeezing block 302, the lifting plate 304 is squeezed by the wedge-shaped squeezing block 302 and rotates upward along the rotating rod 303. At this time, the lifting plate 304 drives the several battery modules 205 above the lifting plate 304 to move upward, and the battery module 205 drives the battery negative electrode 501 and the battery positive electrode 502 above 502 squeezes the negative connecting plate 504 and the positive connecting plate 506 upwards. At this time, the negative connecting plate 504 squeezes the negative squeezing spring 503 upwards, so that the contraction elastic force of the negative squeezing spring 503 increases, and the positive connecting plate 506 squeezes the positive squeezing spring 505 upwards, and the contraction elastic force of the positive squeezing spring 505 increases. This arrangement is beneficial to increase the connection strength of several output endpoints, avoid the phenomenon of virtual connection between the battery negative electrode 501 and the battery positive electrode 502 on the battery module 205, thereby enhancing the working stability of the device.
