Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the scope of protection of the present application.

[0047] Please refer to Figures 1 to 25 The present application provides a technical solution: a new energy storage box, comprising a storage box 1, the top surface of the storage box 1 is provided with a heat dissipation hole 11, the inner side surface of the storage box 1 is slidingly connected with a battery mounting rack 2, the inner side surface of the storage box 1 is fixedly connected with a battery socket 21, both sides of the storage box 1 are provided with a stretching guide rail 3, the outer side surface of the stretching guide rail 3 is provided with a control seat 4, the inner side surface of the storage box 1 is provided with an auxiliary spring 5, and the inner side surface of the storage box 1 is provided with a bottom connecting seat 6.

[0048] The storage box 1 is used for installing and protecting internal components, and is used for installing the battery mounting rack 2 and the battery pack, the heat dissipation hole 11 is used for heat dissipation of the internal battery pack, the battery pack is installed on the battery mounting rack 2 and connected with the battery socket 21, the battery mounting rack 2 can be pulled out from the inside of the storage box 1 and turned by 90 degrees, so that the battery pack is in a vertical state for maintenance and replacement.

[0049] The stretching guide rail 3 comprises two side guide rails 31 which are slidably connected with the inner side surface of the storage box 1, the outer side surface of the two side guide rails 31 is rotatably connected with equidistantly distributed guide rail rollers 311, the two sides of the storage box 1 are provided with guide rail sliding grooves 312, the outer side surface of the stretching guide rail 3 is rotatably connected with two side pull rods 32, the outer side surface of the two side pull rods 32 is fixedly connected with a connecting rotating shaft 321.

[0050] The stretching guide rail 3 is symmetrically distributed on the two sides of the storage box 1, the two side guide rails 31 are slidably connected with the inner side surface of the guide rail sliding grooves 312, the two side pull rods 32 are slidably connected with the outer side surface of the storage box 1, and the connecting rotating shaft 321 penetrates the two side guide rails 31.

[0051] The control seat 4 comprises a movable shell 41 which is slidably connected with the inner side surface of the storage box 1, the outer side surface of the movable shell 41 is provided with a straight slot 42 and an arc slot 421, the inner side surface of the movable shell 41 is rotatably connected with a rotating crank 43, one end of the rotating crank 43 is hingedly connected with a connecting rod 431, one end of the connecting rod 431 is hingedly connected with a connecting sliding block 44, the outer side surface of the connecting sliding block 44 is fixedly connected with a sliding protrusion 441 and a rotating protrusion 442.

[0052] The straight slot 42 intersects with the arc slot 421, the rotating crank 43, the connecting rod 431 and the connecting sliding block 44 are all slidably connected with the inner side surface of the movable shell 41, the sliding protrusion 441 and the rotating protrusion 442 are both slidably connected with the inner side surface of the straight slot 42, the sliding protrusion 441 is slidably connected with the inner side surface of the arc slot 421, the connecting rotating shaft 321 penetrates the movable shell 41 and is rotatably connected with the inner wall thereof, the connecting rotating shaft 321 is fixedly connected with the rotating center of the rotating crank 43, and the sliding protrusion 441 and the rotating protrusion 442 are both fixedly connected with the battery mounting rack 2.

[0053] Through the cooperation of the stretching guide rail 3 and the control seat 4, the battery mounting rack 2 is pushed and pulled, the battery group is controlled to be connected with or disconnected from the battery socket 21, and the battery mounting rack 2 is flipped to be vertical, in the process of use, the battery mounting rack 2 is fixedly connected with the sliding protrusion 441 and the rotating protrusion 442, when the sliding protrusion 441 and the rotating protrusion 442 move and rotate in the movable shell 41, the battery mounting rack 2 also moves and rotates, the connecting rotating shaft 321 penetrates the movable shell 41, when the connecting rotating shaft 321 moves, the movable shell 41 is driven to move, since the sliding protrusion 441 and the rotating protrusion 442 are also in the movable shell 41, the battery mounting rack 2 is also driven to move;

[0054] By pushing and pulling the two sides of the pull rod 32, the two sides of the guide rail 31 can slide in the guide rail groove 312. The surface of the guide rail roller 311 is in contact with the guide rail groove 312, which converts sliding friction into rolling friction, thereby reducing friction. When the two sides of the guide rail 31 move, the connecting shaft 321 also moves, thereby pushing and pulling the battery mounting rack 2;

[0055] The two sides of the pull rod 32 and the connecting shaft 321 can rotate on the two sides of the guide rail 31. The connecting shaft 321 is fixedly connected with the rotating crank 43, thereby driving the rotating crank 43 to rotate;

[0056] The rotating crank 43, the connecting rod 431, and the connecting slider 44 form a crank slider structure. The connecting slider 44 is limited in the straight slot 42 and can only move horizontally by the sliding protrusion 441 and the rotating protrusion 442;

[0057] In the initial state, the two sides of the pull rod 32 are behind the storage box 1, the connecting slider 44 is on one side of the straight slot 42 away from the arc slot 421, and the sliding protrusion 441 and the rotating protrusion 442 are in the straight slot 42. When the two sides of the pull rod 32 are rotated to the vertical state, the rotating crank 43 follows the rotation and pulls the connecting slider 44 forward through the rotating connecting rod 431. At this time, the rotating protrusion 442 is at the end of the straight slot 42 on the other side and cannot continue to move, while the sliding protrusion 441 is at the intersection of the straight slot 42 and the arc slot 421, causing the battery mounting rack 2 to move forward;

[0058] If the two sides of the pull rod 32 are continued to be rotated to be in front of the storage box 1, the rotating crank 43 follows the rotation, but the rotating protrusion 442 cannot continue to move forward at this time, and the connecting slider 44 cannot be pulled forward, thereby taking the rotating protrusion 442 as the rotation center, pulling the sliding protrusion 441 to move into the arc slot 421, causing the connecting slider 44 to rotate around the rotating protrusion 442, until the sliding protrusion 441 slides to directly above the sliding protrusion 441. At this time, the connecting slider 44 is rotated by ninety degrees, causing the battery mounting rack 2 to be rotated by ninety degrees;

[0059] The overall process of pulling out the battery mounting rack 2 from the storage box 1 is as follows. First, the two sides of the pull rod 32 are behind the storage box 1, the battery pack on the battery mounting rack 2 is connected with the battery socket 21, the two sides of the pull rod 32 are rotated to be vertical upward, the battery mounting rack 2 moves a distance on the movable shell 41, thereby separating the battery pack from the battery socket 21. At this time, the separation action is achieved by the rotation of the two sides of the pull rod 32, which saves labor by using the principle of leverage to facilitate pulling out. The two sides of the pull rod 32 are pulled to pull out the two sides of the guide rail 31 from the storage box 1, and the battery mounting rack 2 is also pulled out. When the battery mounting rack 2 needs to be rotated to be vertical, the two sides of the pull rod 32 are rotated for the second time, and the battery mounting rack 2 is also vertical;

[0060] Since the sliding convex block 441 and the rotating convex block 442 are located at the middle front position of the connection of the battery mounting rack 2, the rotating center of the battery mounting rack 2 is also at the middle front position, and the required space of the top during rotation is small, and the battery mounting rack 2 does not need to be pulled out from the storage box 1 to rotate the battery mounting rack 2 to make the battery stand up.

[0061] The auxiliary spring 5 comprises a fixed mounting rack 51 and a driven mounting rack 511, the fixed mounting rack 51 is fixedly connected with the inner side surface of the storage box 1, the driven mounting rack 511 is rotationally connected with the connecting shaft 321, the outer side surfaces of the fixed mounting rack 51 and the driven mounting rack 511 are fixedly connected with the force storage spring 52, the other end of the force storage spring 52 is fixedly connected with the connecting block 53, both ends of the connecting block 53 are fixedly connected with the spring connecting seat 531, the bottom surface of the spring connecting seat 531 is provided with the convex block pressing groove A 5311, the bottom surface of the connecting block 53 is provided with the convex block connecting groove 532, and the bottom surface of the connecting block 53 is provided with the convex block pressing groove B 5321, the outer side surfaces of the fixed mounting rack 51 and the driven mounting rack 511 are hingedly connected with the hinged arm 54, the other end of the hinged arm 54 is hingedly connected with the hinged seat 541, and the inner side surface of the hinged seat 541 is provided with the rotation limiting groove 542.

[0062] The connecting shaft 321 penetrates the driven mounting rack 511, the force storage spring 52 is fixedly connected with the connecting block 53 through the spring connecting seat 531, the inner side surface of the hinged seat 541 is rotationally connected with the symmetrically distributed hinged arms 54, and one side of the hinged arms 54 is hingedly connected with the spring connecting seat 531.

[0063] The fixed mounting rack 51 and the driven mounting rack 511 are located at both ends, the connecting block 53, the force storage spring 52 and the spring connecting seat 531 are symmetrically distributed at both ends, the hinged seat 541 is distributed at both sides, and each hinged seat 541 is hingedly connected with the symmetrically and same-side hinged arms 54.

[0064] The fixed mounting rack 51 is hingedly connected with one side of the hinged arms 54, and the other hinged arm 54 on the same side of the hinged arms 54 is hingedly connected with the spring connecting seat 531 at the other end, and the driven mounting rack 511 is hingedly connected with one side of the hinged arms 54, and the other hinged arm 54 on the same side of the hinged arms 54 is hingedly connected with the spring connecting seat 531 at the other end.

[0065] The bottom connecting seat 6 comprises a fixed base 611 and a movable base 621. The fixed base 611 is fixedly connected with one side connecting block 53. The outer side surface of the fixed base 611 is provided with a lifting sliding groove 612. The top surface of the fixed base 611 is fixedly connected with a fixed protrusion 613. The outer side surface of the movable base 621 is fixedly connected with a lifting sliding block 622. The inner side surface of the movable base 621 is slidingly connected with a movable protrusion 623. The inner side surface of the movable base 621 is fixedly connected with a protrusion spring 6231. The inner side surface of the storage box 1 is fixedly connected with a supporting platform 63. One end of the supporting platform 63 is provided with a falling inclined chute 631.

[0066] The lifting sliding block 622 is slidingly connected with the inner side surface of the lifting sliding groove 612. The fixed protrusion 613 and the movable protrusion 623 are both slidingly connected with the inner side surface of the protrusion connecting groove 532. The movable protrusion 623 is slidingly connected with the inner side surfaces of the protrusion pressing groove A 5311 and the protrusion pressing groove B 5321. The two ends of the protrusion spring 6231 are fixedly connected with the movable protrusion 623 and the movable base 621 respectively. The fixed base 611 and the movable base 621 are both slidingly connected with the inner side surface of the falling inclined chute 631.

[0067] Through the cooperation of the auxiliary spring 5 and the bottom connecting seat 6, the effect of labor-saving pulling out and pushing back is realized. In the process of use, the fixed mounting frame 51 and the driven mounting frame 511 are at both ends. The fixed mounting frame 51 is fixedly connected with the inside of the storage box 1 and does not move. The driven mounting frame 511 is penetrated by the connecting shaft 321 and will be pulled out of the storage box 1 along with the battery mounting frame 2.

[0068] The fixed mounting frame 51 and the driven mounting frame 511 are connected with symmetrical connecting blocks 53, force storage springs 52 and spring connecting seats 531. The connecting blocks 53 at both ends are separated, but can be connected by the bottom connecting seat 6. When the fixed mounting frame 51 and the driven mounting frame 511 move away from each other, the middle force storage spring 52 will be pulled.

[0069] The fixed base 611 and the movable base 621 are used to connect the middle separated connecting blocks 53. The movable base 621 can be vertically lifted on the fixed base 611, but cannot be horizontally separated. When they are both above the supporting platform 63, the movable base 621 is supported at the bottom. The fixed base 611 and the movable base 621 are at the same height. The fixed protrusion 613 and the movable protrusion 623 are inserted into the protrusion connecting groove 532 of the connecting block 53 on both sides, so as to connect the connecting blocks 53 at both ends.

[0070] Since the fixed base 611 and the movable base 621 cannot be separated, the connecting blocks 53 at both ends cannot be separated either, which means that the connecting blocks 53 are an integral whole. Therefore, the fixed mounting frame 51 and the driven mounting frame 511 are connected in sequence with the connecting block 53 in the middle, the force storage spring 52, and the spring connecting seat 531. Since the hinged arm 54 and the hinged seat 541 can be arbitrarily unfolded and folded to adapt to different distances between the fixed mounting frame 51 and the driven mounting frame 511, they do not play any role;

[0071] At this time, the two force storage springs 52 are equivalent to being connected in series between the fixed mounting frame 51 and the driven mounting frame 511. When the battery mounting rack 2 is pulled out of the storage box 1, both force storage springs 52 are subjected to tension. After being connected in series, the force on each spring is equal to the total tension. According to Hooke's law, the total deformation is the superposition of the deformation of each spring. Only a small force is needed to produce a large deformation, and the resulting reaction force is small. At this time, it is easier to pull the battery mounting rack 2 out of the storage box 1;

[0072] As the battery mounting rack 2 is further pulled out of the storage box 1, the included angle of each hinged arm 54 gradually increases. However, the rotating limiting groove 542 in the hinged seat 541 restricts it from rotating to one hundred and eighty degrees, and it cannot reach the dead point position.

[0073] At the same time that the battery mounting rack 2 is pulled out, the fixed base 611 and the movable base 621 also slide on the support platform 63 until the movable base 621 passes through the falling chute 631, causing the movable base 621 to descend from the fixed base 611. The movable lug 623 is disconnected from the lug connecting groove 532 in the upper connecting block 53, so the fixed base 611 and the movable base 621 are no longer connected to the connecting blocks 53 on both sides.

[0074] After the connecting blocks 53 are separated, they no longer serve to connect the force storage springs 52 on both sides. At this time, they are equivalent to being non-existent, and the force storage springs 52 on both sides are disconnected. The force storage springs 52 between the fixed mounting frame 51 and the driven mounting frame 511 are not in a series connection state.

[0075] However, at this time, the fixed mounting frame 51 and the driven mounting frame 511 can still be connected to each other through the hinged arm 54. The hinged arm 54 will first be connected to the fixed mounting frame 51, then pass through the same side hinged seat 541 and the hinged arm 54, and finally be connected to the spring connecting seat 531. The spring connecting seat 531 connects the force storage spring 52 to the driven mounting frame 511, forming a connection sequence of the fixed mounting frame 51, the hinged arm 54, the spring connecting seat 531, the force storage spring 52, and the driven mounting frame 511.

[0076] The hinged arm 54 on the other side also forms a connection sequence of the driven mounting frame 511, the hinged arm 54, the spring connecting seat 531, the force storage spring 52, and the fixed mounting frame 51, starting from the driven mounting frame 511.

[0077] In this way, both storage springs 52 are connected between the fixed mounting bracket 51 and the driven mounting bracket 511. The two are independent of each other and are equivalent to being connected in parallel. Each spring only bears half of the total tension, and according to Hooke's Law, the deformation becomes half of the original.

[0078] During the process of changing from series to parallel connection, the tension of each spring decreases, and the deformation amount changes from twice to half. It is equivalent to replacing it with a new spring with four times the stiffness to hold the same amount of elongation. As a result, the reaction force becomes four times the original. When the battery mounting bracket 2 is flipped back to the horizontal position and then pushed back into the storage box 1, the reset action of the storage spring 52 will assist in pulling the battery mounting bracket 2 back, thus saving more effort.

[0079] When the battery mounting bracket 2 is pushed back into the interior, the auxiliary spring 5 returns to its initial state. During the movement of the movable protrusion 623, the movable base 621 returns to the top of the support platform 63 and then returns to contact the inclined surfaces of the protrusion pressing groove A5311 and the protrusion pressing groove B5321, pressing it into the interior until it contacts the protrusion connecting groove 532. The protrusion spring 6231 pushes the movable protrusion 623 out again, and the connecting blocks 53 at both ends return to the connected state.

[0080] After the guide rails 31 on both sides reach the bottom of the guide rail groove 312, the battery mounting bracket 2 can no longer be pushed backward. At this time, the pull rods 32 on both sides are rotated to the rear of the storage box 1, so that the battery mounting bracket 2 moves backward a distance on the movable outer shell 41. By using leverage to save effort, the battery pack is inserted into the battery socket 21 and the battery pack is connected.

[0088] In this embodiment, as Figure 15 , Figure 16 As shown, the rotation limiting groove 542 inside the hinge seat 541 limits the maximum rotation angle of the hinge arm 54, so that the hinge arms 54 on both sides cannot be horizontal and will not be in a dead position.

[0089] In this embodiment, as Figure 17 , Figure 18 As shown, the connecting block 53 is connected by the fixed base 611 and the movable base 621, which is equivalent to the connecting blocks 53 at both ends being a whole, and the storage springs 52 being in series.

[0091] In this embodiment, as Figure 21 As shown, the dashed area represents the assumption that the fixed mounting bracket 51 and the driven mounting bracket 511 are extended, thereby separating the two independent parallel areas. One side is the connection sequence of the fixed mounting bracket 51, the hinge arm 54, the spring connecting seat 531, the storage spring 52, and the driven mounting bracket 511, while the other side is the connection sequence of the driven mounting bracket 511, the hinge arm 54, the spring connecting seat 531, the storage spring 52, and the fixed mounting bracket 51. The two sides are independent of each other, and the whole is in a parallel relationship.
