DETAILED DESCRIPTION

[0021] The specific implementation methods of the utility model are further explained in detail below with reference to the accompanying drawings through the description of embodiments, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and to facilitate their implementation.

[0022] like Figures 1 to 5 As shown, the battery locking structure of the battery transport trolley includes a support platform 1 and a base 2. The support platform 1 is arranged on the base 2, and one end of the bottom of the base 2 passes through the support platform 1. A first slider 3 is provided at the bottom of the support platform 1, and a first inclined surface 4 is provided on the first slider 3. A second slider 5 is provided at one end of the bottom of the base 2, and a second inclined surface 6 is provided on the second slider 5. The first inclined surface 4 is in contact with the second inclined surface 6. A protrusion 7 is provided on the upper end of the base 2, and a spring 8 is connected to the end of the base 2.

[0023] The structure consists of a support platform 1 and a base 2. The support platform 1 and the base 2 are combined as a battery support load-bearing platform for the transport trolley. The first inclined plane 4 and the second inclined plane 6 are designed to realize the relative sliding of the support platform 1 and the base 2. The transport trolley can be placed at the end of the transport track. The other end of the spring 8 is connected to the transport trolley. Through the compression of the spring 8, the compressed movement of the support platform 1 can synchronously drive the base 2 to move. Under the constraints of the base 2 and the protrusion 7, the purpose of fixing the battery pack is achieved. The support platform 1 and the base 2 can be reset by the reset action of the spring 8; after the battery pack is placed on the support platform 1, the support platform 1 and the base 2 are moved. After the base 2 moves, the protrusion 7 can form a fixed constraint on one end of the battery pack to prevent unstable factors such as shaking of the battery pack. The battery pack will not be able to break away from the transport trolley due to the shaking of the ship, and the transport trolley can stably transfer the battery pack. Among them, the distance between the upper end surface of the support platform 1 and the protrusion 7 when it moves down to the lowest position is adapted to the height of the battery pack, so that the battery pack can be clamped; the components located below the first slider 3 on the transport trolley need to provide avoidance space for the support platform 1 to move downward; the bottom of the base 2 is smoothed or a low friction coefficient material is selected to reduce the resistance to the movement of the base 2.

[0024] like Figure 3As shown, a platform 9 is provided at the top of the support platform 1, and a step 10 is provided at the side of the base 2. The step 10 can limit the movement of the platform 9 and provide support for the platform 9. After the battery pack is placed, when the support platform 1 moves down to the platform 9 and overlaps the step 10, the support platform 1 moves to the lowest position, and the platform 9 is supported by the step 10 and is in a horizontal position. The battery pack can also maintain a stable horizontal posture, which is conducive to the transport trolley to move and transfer the battery pack.

[0025] like Figure 2 and Figure 5 As shown, an opening 11 is provided between the first sliders 3, a stopper 14 is provided at the bottom of the opening 11, one end of the base 2 passes through the opening 11, and the stopper 14 is located below the base 2; a slide groove 15 is provided on the inner side of the first slider 3, a protrusion 16 is provided on the stopper 14, the slide groove 15 cooperates with the protrusion 16, a bolt 12 is connected to the bottom end of the first slider 3, a threaded hole 17 is provided on the stopper 14, the threaded hole 17 passes through the stopper 14, and the bolt 12 passes through the first slider 3 and cooperates with the threaded hole 17. The stopper 14 serves as the anti-detachment structure of the structure. The upper end of the stopper 14 is at a certain distance from the bottom of the base 2, and will not hinder the downward movement of the support platform 1. The bottom of the support platform 1 is hollowed out to form an opening 11, and one end of the base 2 passes through the opening 11 of the support platform 1. The stopper 14 is placed in the middle of the lower part of the support platform 1 and locked by bolts 12. After the two bolts 12 are connected with the threaded holes 17, the stopper 14 is fixed, and the support platform 1 and the base 2 form an inseparable structure. When the spring 8 resets the support platform 1 and is lifted up, the stopper 14 presses against the bottom of the base 2 to prevent the battery pack from being taken out. The stopper 14 can also prevent the support platform 1 from being ejected due to excessive pressure when the spring 8 is reset, thereby ensuring safe and reliable operation. When the support platform 1 and the base 2 lose their functions due to wear or the risk increases and maintenance is required, the support platform 1 and the base 2 can be separated by unscrewing the removal bolts 12 and pulling the stopper 14 out along the slide 15. The slide grooves 15 and the protrusions 16 are arranged in pairs, which can improve the guiding accuracy when the stopper 14 is installed and removed.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, a third inclined surface 13 is provided at the end of the protrusion 7. When the battery pack is taken out, the third inclined surface 13 provides an escape space for the battery pack to facilitate the process of taking out the battery pack.

[0027] like Figures 1 to 4 As shown, the spring 8, the first slider 3 and the second slider 5 are all arranged in pairs. The spring 8 is arranged in pairs to improve the accuracy of the direction of the force acting on the base 2, the first slider 3 and the second slider 5 are arranged in pairs to expand the contact area between the two, and the base 2 forms two supporting points for the support platform 1, which is conducive to improving the stability of the support platform 1 and the base 2 during relative movement.

[0028] like Figure 3 and Figure 4 As shown, the platform 9 is a square structure, and a groove structure is formed between the protrusion 7 and the step 10. The platform 9 is designed to be square, and its structure is simple, which can be easily processed and reduce the cost of component replacement. The space of the slide groove 15 between the protrusion 7 and the step 10 is used to place the end of the platform 9 and the battery pack, thereby improving the stability of the support platform 1 and the battery pack.

[0029] A wear-resistant layer is provided on the first inclined surface 4 and the second inclined surface 6. The wear-resistant layer can reduce the wear of the inclined surface and increase its service life. There is a lubricating liquid between the support platform 1 and the base 2 to reduce the friction resistance and enable the support platform 1 and the battery pack to reach the lowest position faster.

[0030] When the battery pack is not placed, the support platform 1 has its own weight and exerts a force on the second inclined surface 6. The compression spring 8 of this force shortens the spring 8 by a certain distance. The reaction force of the spring 8 pushes the base 2, and the first inclined surface 4 and the second inclined surface 6 have friction. Therefore, the support platform 1 is stationary under the balance of its own weight, the friction force of the second inclined surface 6 and the normal supporting force of the second inclined surface 6.

[0031] The usage process is as follows: when the battery pack is put down, the support platform 1 is under downward pressure due to the action of gravity, and the base 2 is under pressure applied by the support platform 1. Because the contact surface between the two is an inclined surface, the base 2 is subjected to the horizontal component force and the spring 8 is compressed, and the base 2 immediately moves toward the spring 8. When the spring 8 is compressed to a certain length sufficient to support the battery pack, the platform 9 abuts against the step 10 and the protrusion 7 hooks the end of the battery pack. The battery pack is constrained to form a locked state, and the battery pack cannot fall off, and the battery pack can be transferred subsequently by a transport cart; when the stacker removes the battery pack, the spring 8 loses its constraint, and the spring 8 applies a thrust to the base 2 during the reset process, and the base 2 moves away from the spring 8, the support platform 1 is lifted up and the locked state is released. At the same time, under the limiting action of the block 14, the support platform 1 cannot fall off the base 2, thereby ensuring the safety and reliability of use.

[0032] The battery locking structure of the battery handling trolley utilizes the mutual linkage displacement of the support platform 1 and the base 2 to lock the battery pack through the support of the support platform 1 and the limiting and restraining effect of the base 2 and the protrusion 7, thereby effectively improving the stability of the battery pack during transfer and transportation, ensuring the stability of the battery pack and avoiding damage to the battery pack. It is suitable for the battery replacement process on ships, and at the same time replaces the inconvenient manual handling, thereby improving the safety of battery handling. The mechanical structure design of the support platform 1 and the base 2 is ingenious, simple in structure, small in space, easy to maintain, and highly reusable.

[0033] The above is an exemplary description of the utility model in conjunction with the accompanying drawings. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model; or the above concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
