The energy storage electric box is a large-capacity mobile power supply, a machine that can store electrical energy. The energy storage electric box is mainly used for emergency handling and to meet the demand for outdoor power supply. In the event of a sudden power outage at home, it can meet the power demand of small-power electrical appliances. When camping outdoors, it can be used to charge equipment. The energy storage electric box is designed for outdoor emergencies. The product is light in weight, large in capacity and high in power.

[0031] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] Reference Figures 1 to 10 :

[0033] A protective structure for an energy storage box includes four fixed support legs 2 for supporting the box, the fixed support legs 2 consisting of a right-angle guard plate 21 and a support plate 22; two fixed support legs 2 located on the same side are slidably mounted on a first centering component 3, the first centering component 3 drives the two fixed support legs 2 on the same side to move in the horizontal direction to adjust the spacing; the two first centering components 3 are slidably mounted on a second centering component 4, the second centering component 4 drives the two first centering components 3 to move in the horizontal direction perpendicular to the moving direction of the working end of the first centering component 3 to adjust the spacing; the second centering component 4 is fixedly mounted on a sliding inner box 5, the sliding inner box 5 is slidably mounted inside a fixed outer box 6, and the fixed outer box 6 is provided with buffer units 61 and auxiliary support plates 62 at both ends of the sliding inner box 5 in the moving direction, the buffer unit 61 buffers the sliding inner box 5 subjected to inertial movement, and the auxiliary support plate 62 located on one side of the sliding inner box 5 in the moving direction applies a supporting force to the box fixed on the fixed support legs 2.

[0034] The energy storage box protection structure in the present application can be used to protect the box during transportation, wherein the four fixed support legs 2 are respectively installed at the four top corners of the bottom of the energy storage box. The fixed support legs 2 can cover the four top corners of the bottom of the energy storage box, thereby lifting the energy storage box to avoid direct contact between the top corners, bottom and sides with the ground to cause collision or friction. The two fixed support legs 2 on the same side are respectively installed at the two ends of the first centering component 3. The first centering component 3 can change the spacing between the fixed support legs 2 so that the right-angle guard plate 21 of the fixed support legs 2 fits the side of the energy storage box. The first centering component 3 is slidably installed at both ends of the second centering component 4. The second centering component 4 can change the spacing between the first centering components 3 so that the distance between the first centering components 3 can be changed. The two sides of the right-angle guard plate 21 are completely in contact with the right-angle sides of the energy storage box. In this embodiment, the position of the fixed support foot 2 is adjusted by the first centering component 3 and the second centering component 4, so that the fixed support foot 2 can effectively fix energy storage boxes of different sizes. The first centering component 3 and the second centering component 4 are installed on the sliding inner box 5. The energy storage box and the sliding inner box 5 The position is relatively fixed, and the sliding inner box 5 is slidably installed in the fixed outer box 6. When transporting the energy storage box, the staff places the fixed outer box 6 in the carriage so that the sliding direction of the sliding inner box 5 is the same as the moving direction of the transport vehicle. During the acceleration or braking process of the transport vehicle, the energy storage box drives the sliding inner box 5 to slide in the fixed outer box 6 under the action of inertia. The buffer units 61 provided at both ends of the sliding inner box 5 in the moving direction of the fixed outer box 6 are used to buffer the movement of the sliding inner box 5, ensuring that the energy storage box has a certain displacement to relieve the pressure of inertia on the surface of the energy storage box, and the fixed outer box 6 Auxiliary support plates 62 are also provided on both sides of the moving direction of the sliding inner box 5. The auxiliary support plates 62 can fit the moving side of the energy storage box after the sliding inner box 5 moves a certain distance, and apply a reverse support force to stop the energy storage box and the sliding inner box 5 from moving. The buffer unit 61 of the fixed outer box 6 and the auxiliary support plates 62 cooperate to keep the energy storage box vertically placed during transportation, and will not fall over due to inertia during acceleration and braking. It also avoids friction and collision on the bottom, top corners and sides of the energy storage box, effectively protecting the structure of the energy storage box and the internal electrical components.

[0035] In order to solve the problem of the energy storage box being squeezed at the top corner of the right-angled guard plate 21 of the fixed support leg 2 due to inertia, the following features are specifically set:

[0036] The right-angled guard plate 21 and the support plate 22 of the fixed support leg 2 are made of rubber material on the side in contact with the surface of the electrical box.

[0037] The side of the right-angle protection plate 21 and the support plate 22 in contact with the energy storage electric box is provided with a rubber material, which can be a rubber sheet, so as to avoid the direct contact of the hard material with the surface of the energy storage electric box. When the energy storage electric box is extruded to one side under the action of inertia, the rubber material can be deformed to a certain extent and automatically reset after the inertia disappears, thereby preventing the surface of the energy storage electric box from being contacted with the top corner of the right-angle protection plate 21 and causing indentation on the surface of the energy storage electric box.

[0038] In order to achieve the purpose that the buffer unit 61 can buffer the movement of the sliding inner box 5 in different directions, the following features are specifically provided:

[0039] The two end outer walls of the sliding inner box 5 are attached to the two end inner walls of the fixed outer box 6. The buffer unit 61 includes an abutting plate 611 arranged on the two sides of the sliding inner box 5 not in contact with the fixed outer box 6. The abutting plate 611 is provided with at least two horizontally extending guide rods 612, the guide rods 612 are inserted into the first guide holes 63 on the two sides of the fixed outer box 6, a return spring 613 is sleeved on the guide rod 612, the return spring 613 applies a spring force to the abutting plate 611 to move towards the sliding inner box 5, and a limiting head 614 with a side length greater than the diameter of the guide rod 612 is arranged at one end of the guide rod 612 outside the fixed outer box 6.

[0040] In the embodiment, the two end outer walls of the sliding inner box 5 are attached to the two end inner walls of the fixed outer box 6, thereby ensuring that the sliding inner box 5 can only move in a single direction inside the fixed outer box 6. When the staff places the energy storage electric box in the carriage, it is ensured that the moving direction of the sliding inner box 5 is the same as the advancing direction of the transport vehicle. The buffer unit 61 is arranged on both sides of the moving direction of the sliding inner box 5, thereby ensuring that the sliding inner box 5 can be buffered by the buffer unit 61 regardless of which side it moves. The abutting plate 611 of the buffer unit 61 is inserted into the first guide holes 63 on the two sides of the fixed outer box 6 through the guide rod 612, and the return spring 613 sleeved on the guide rod 612 applies a spring force to the abutting plate 611 to attach to the surface of the sliding inner box 5. When the energy storage electric box and the sliding inner box 5 move to one side under the action of inertia, the abutting plate 611 is pushed to move, the abutting plate 611 is compressed to move the return spring 613, thereby relieving the inertia suffered by the energy storage electric box and maintaining the balance and stability of the energy storage electric box. When the inertia suffered by the energy storage electric box gradually disappears, the spring force of the return spring 613 gradually drives the abutting plate 611 to reset, thereby pushing the sliding inner box 5 and the energy storage electric box to reset. The limiting head 614 arranged on one side of the guide rod 612 prevents the guide rod 612 of the abutting plate 611 from being separated from the first guide hole 63 of the fixed outer box 6.

[0041] In order to achieve the purpose that the sliding inner box 5 automatically attaches to the auxiliary support plate 62 on one side of the fixed outer box 6 when it moves to one side, the following features are specifically provided:

[0042] The abutment plate 611 is provided with a horizontally extending push rod 615, which extends parallel to the guide rod 612 toward one side of the auxiliary support plate 62, and the push rod 615 is inserted into the second guide holes 64 provided on both sides of the fixed outer box 6; horizontal side plates 65 are provided on both sides of the fixed outer box 6, and the side plates 65 are provided with a through opening 651 above the second guide hole 64, and insertion seats 652 are provided on both sides of the opening 651. The auxiliary support plate 62 is inserted into the insertion seat 652 through the rotating shaft 621 extending horizontally on both sides, and the axis of the rotating shaft 621 is perpendicular to the axis of the guide rod 612. The bottom of the auxiliary support plate 62 passes through the opening 651 and contacts the push rod 615. The push rod 615 moves to drive the auxiliary support plate 62 to rotate around the axis of the rotating shaft 621 so that the top of the auxiliary support plate 62 is attached to one side of the electrical box.

[0043] The auxiliary support plate 62 in this embodiment is inserted into the insertion seat 652 on both sides of the fixed outer box 6 through the rotating shaft 621 on both sides. The rotation of the rotating shaft 621 is set horizontally and perpendicular to the axis of the guide rod 612, so that the auxiliary support plate 62 can rotate along the axis of the rotating shaft 621. The auxiliary support plate 62 is located in the opening 651 of the side plate 65 on both sides of the fixed outer box 6. When the bottom of the auxiliary support plate 62 is flipped outward, the top of the auxiliary support plate 62 can be close to the energy storage box and fit the surface of the energy storage box to support the energy storage box. The top rod 615 provided on the abutting plate 611 of the buffer unit 61 is connected to the top rod 615 passing through the opening 651. The bottom inner side of the auxiliary support plate 62 fits in place, and when the energy storage box and the sliding inner box 5 move to one side under the action of inertia, the sliding inner box 5 pushes the abutment plate 611 to compress the reset spring 613, and the top rod 615 moves toward that side and pushes the bottom of the auxiliary support plate 62 on that side of the fixed outer box 6 outward, so that the top end of the auxiliary support plate 62 located in the moving direction of the energy storage box flips toward the energy storage box and abuts against the surface of the energy storage box for support. The auxiliary support plate 62, the energy storage box and the top rod 615 form a triangular stable structure, which effectively prevents the energy storage box from tipping over due to inertia and keeps the energy storage box stable during transportation.

[0044] In order to prevent the top end of the auxiliary support plate 62 from causing dents on the surface of the energy storage box when supporting the surface of the energy storage box, the following features are specifically provided:

[0045] A rubber gasket 622 is provided on the side of the top end of the auxiliary support plate 62 facing the interior of the fixed outer box 6 .

[0046] In this embodiment, a rubber gasket 622 is provided on the side of the top of the auxiliary support plate 62 facing the inside of the fixed outer box 6. When the rubber gasket 622 contacts the surface of the energy storage box, it can prevent the surface of the energy storage box from directly contacting the hard material. The rubber gasket 622 cushions the impact generated when the auxiliary support plate 62 contacts the energy storage box, thereby protecting the flatness of the surface of the energy storage box.

[0047] In order to prevent the sliding inner box 5 from moving too far in the fixed outer box 6, which would result in a large movement of the energy storage box, the following features are specifically provided:

[0048] The straight-line distance between the bottom end of the auxiliary support plate 62 and the axis of the rotating shaft 621 is smaller than the straight-line distance between the top end of the auxiliary support plate 62 and the axis of the rotating shaft 621 .

[0049] In this embodiment, the straight-line distance between the bottom end of the auxiliary support plate 62 and the axis of the rotating shaft 621 is smaller than the straight-line distance between the top end of the auxiliary support plate 62 and the axis of the rotating shaft 621, so that the top rod 615 moves to push the bottom end of the auxiliary support plate 62 to move a shorter distance, so that the top end of the auxiliary support plate 62 can move a larger distance, so that the rubber gasket 622 on the top of the auxiliary support plate 62 quickly contacts the surface of the energy storage box, and cooperates with the friction force of the rubber gasket 622 on the energy storage box and the elastic force of the return spring 613 to stop the movement of the energy storage box and the sliding inner box 5, thereby reducing the stroke of the sliding inner box 5 in the fixed outer box 6 and the shaking amplitude of the energy storage box, thereby ensuring the stability of the energy storage box in the fixed outer box 6.

[0050] In order to achieve the purpose of adjusting the position of the fixed support foot 2 by the first centering component 3 and the second centering component 4, the following features are specifically set:

[0051] The first centering component 3 includes a horizontally arranged first rotating screw 31, and opposite threads are provided on both sides of the first rotating screw 31.

[0052] The second centering component 4 includes a horizontally arranged second rotating screw 41, the axis of the second rotating screw 41 is perpendicular to the axis of the first rotating screw 31, and opposite threads are provided on both sides of the second rotating screw 41. The second rotating screw 41 is limitedly inserted on the second fixed bearing seat 42, and the second fixed bearing seat 42 is located in the middle of the second rotating screw 41. The second fixed bearing seat 42 is fixedly installed at the center of the sliding inner box 5; the bottom of the first fixed bearing seat 32 is provided with a second threaded sleeve 33 which is in the same straight line as the second rotating screw 41, and the first fixed bearing seat 32 is screwed on both ends of the second rotating screw 41 through the second threaded sleeve 33; the two ends of the second rotating screw 41 are provided with a turning handle 43, and the cross-sectional shape of the turning handle 43 is rectangular.

[0053] In this embodiment, the first centering component 3 and the second centering component 4 adopt the same structure, the fixed support leg 2 is screwed on the two ends of the first rotating screw 31 of the first centering component 3 through the first threaded sleeve 211 on one side of the right-angle guard plate 21, and the threads at the two ends of the first rotating screw 31 are set oppositely, so that when the first rotating screw 31 rotates, the fixed support leg 2 can be driven to move relative to or toward each other, and the center plane of the first rotating screw 31 is used as the symmetry plane for synchronous movement, changing the spacing between the fixed support legs 2 on the same side of the energy storage box, and the first fixed bearing seat 32 that fixes the position of the first rotating screw 31 is screwed on the second threaded sleeve 33. The threads at both ends of the second rotating screw 41 of the second centering assembly 4 are arranged in opposite directions, so that when the second rotating screw 41 rotates, it can drive the first centering assembly 3 and the fixed support legs 2 at both ends of the first centering assembly 3 to move relative to or toward each other, and move synchronously with the center plane of the second rotating screw 41 as the symmetry plane, changing the spacing between the fixed support legs 2 at both ends of the energy storage box to achieve clamping of energy storage boxes of different sizes. The second fixed bearing seat 42 is fixedly installed on the sliding inner box 5, thereby ensuring that the energy storage box is located at the center of the sliding inner box 5 and the sliding inner box 5 moves the same distance to both sides of the fixed outer box 6. The staff can use a tool to rotate the handles 43 at both ends of the first rotating screw 31 and the second rotating screw 41 to drive the first rotating screw 31 and the second rotating screw 41 to rotate.

[0054] In order to achieve the purpose that the fixed support foot 2 and the first fixed bearing seat 32 can only move without rotating when the first rotating screw 31 and the second rotating screw 41 rotate, the following features are specifically provided:

[0055] The bottom of the first fixed bearing seat 32 is also provided with at least one limit block 321, and the limit block 321 is slidably installed in the slide groove 51 set on the upper side of the sliding inner box 5. The slide groove 51 extends along the length direction of the second rotating screw 41, and the upper surface of the slide groove 51 is in contact with the bottom of the support plate 22 of the fixed support foot 2.

[0056] In this embodiment, a slide groove 51 is provided on the sliding inner box 5, and a limit block 321 is provided at the bottom of the first fixed bearing seat 32 to limit the insertion into the slide groove 51. The limit block 321 limits the first fixed bearing seat 32 to ensure that the first fixed bearing seat 32 can only move along the length direction of the slide groove 51 under the drive of the second rotating screw 41 and cannot rotate. The upper surface of the slide groove 51 also fits the bottom of the support plate 22 of the fixed support leg 2, and cooperates with the pressure of the energy storage box on the support plate 22 of the fixed support leg 2 to ensure that the fixed support leg 2 cannot rotate when the first rotating screw 31 rotates and can only move horizontally.
