Description

Technical Field

[0001] This utility model relates to the field of energy storage battery pack technology, specifically a portable solar energy storage battery pack. Background Technology

[0002] A storage battery is a device that stores energy by converting chemical energy into electrical energy. Its core functions include storing excess electrical energy and releasing it when needed to balance power supply and demand and improve energy efficiency. When storing electricity generated by solar energy, lithium iron phosphate battery packs are often used. A lithium iron phosphate battery pack consists of multiple lithium iron phosphate batteries connected in series or parallel. Due to their large number, size, and weight, they are often carried manually by hand, which is labor-intensive. To improve this situation, a portable solar energy storage battery pack is proposed.

[0003] A portable energy storage lithium battery pack, as disclosed in authorization announcement number CN218783172U, includes a shell, a top cover, a handle, and a battery pack body. The top cover is located on top of the shell and is hinged to the top of the shell. The top cover is fixedly installed to the shell by a case lock. The front of the shell is fixedly connected to the back of the handle. The interior of the shell is movably connected to the surface of the battery pack body. The shock-absorbing rubber is located inside the shell and is fixedly connected to the inner wall of the shell. The inner side of the shock-absorbing rubber is fixedly connected to the surface of the battery pack body.

[0004] Although it achieves the goal of making the energy storage lithium battery pack into a suitcase shape by setting the outer shell, top cover and handle, allowing users to carry it with one hand and improving the portability of the energy storage lithium battery pack, at the same time the shock-absorbing rubber and cushioning rubber will dampen the battery pack body and prevent the battery pack body from colliding with the outer shell due to shaking when carrying the energy storage lithium battery pack.

[0005] However, this does not solve the problem that existing energy storage battery packs are not easy to plug in and fix into the battery pack, nor are they easy to implement multiple limiting and anti-shaking measures for the battery pack, which affects the stability of use and the convenience of carrying. Utility Model Content

[0006] The purpose of this utility model is to provide a portable solar energy storage battery pack to solve the problems mentioned in the background art, such as the inconvenience of conveniently inserting and fixing batteries to form a battery pack, the difficulty in performing multiple limiting and anti-shaking measures on the battery pack, and the impact on the stability and portability of the battery pack.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a portable solar energy storage battery pack, comprising a housing and a lifting rope. The lifting rope is provided at the top of the housing and is fixedly connected to the housing. A base is installed inside the housing. A lower placement frame is provided at the top of the base. Multiple sets of equally spaced limiting posts are installed at the bottom of the lower placement frame. Multiple sets of equally spaced limiting holes are provided on the surface of the base, and the limiting posts can be inserted into the limiting holes and slidably connected to the limiting holes. Multiple sets of battery bodies are provided at the top of the lower placement frame. Two sets of plug-in seats are symmetrically installed on the side wall of the lower placement frame. An upper placement frame is provided above the lower placement frame, and two sets of vertical rods are symmetrically installed on the side wall of the upper placement frame.

[0008] Preferably, the interior of the box on both sides of the lower placement frame is provided with a clamping plate, and the side of the clamping plate near the box is provided with multiple sets of first springs at equal intervals, and the first springs are fixedly connected to the box.

[0009] Preferably, each of the vertical rods has a plug-in post installed at its bottom end, and the plug-in post can be inserted into the interior of the plug-in socket and slidably connected to the plug-in socket.

[0010] Preferably, each of the plug-in sockets has a limiting ring on its side wall, and the limiting ring is fixedly connected to the plug-in socket.

[0011] Preferably, each of the limiting rings has a pull-out post inside, and the pull-out post is slidably connected to the limiting ring.

[0012] Preferably, each of the pull-out columns is provided with a second spring, and the two ends of the second spring are respectively connected to the pull-out column and the limiting ring.

[0013] Preferably, the surface of each insertion post is provided with a limiting groove, and the pull-out post can be inserted into the limiting groove and slidably connected with the limiting groove.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the energy storage battery pack not only realizes the convenient insertion and positioning of the battery pack, which facilitates multiple positioning and anti-shaking measures for the battery pack, but also improves the stability of use and the convenience of carrying.

[0015] Multiple battery cells are arranged and installed on the surface of the lower placement frame. The upper placement frame is then aligned with the battery cells, and pressed down onto the upper surface of the battery cells. Simultaneously, the upper placement frame moves the vertical rod downwards, causing the insertion pin to insert into the connector. The insertion pin moves the pull-out pin outwards within the limiting ring, compressing the second spring. When the limiting groove reaches the pull-out pin position, the second spring causes the pull-out pin to reset, locking it into the limiting groove, thus securing the insertion pin to the connector. With the cooperation of multiple insertion pins and connectors, the upper and lower placement frames are connected. The positive and negative terminals of the battery cells are then connected in series or parallel to form a lithium iron phosphate battery pack. The battery pack is then removed, the casing is opened, and the limiting pin is aligned with the limiting ring. The battery pack is placed on the base through a positioning hole. The limiting posts and holes work together to prevent the battery pack from shaking. Simultaneously, as the battery pack moves, it moves the clamping plate, which compresses the first spring. The first spring, in turn, provides a counterforce to the clamping plate, thus squeezing and limiting the battery pack from both sides to ensure its stability during use. When the device needs to be carried, simply pull the lifting rope to retrieve it to the desired position. It connects to a solar power generation device via the positive and negative terminals on the surface of the casing to store solar energy. This system allows for convenient insertion, limiting, and fixing of the battery pack, facilitating multiple limiting and anti-shake measures, improving stability and portability.

[0025] Example 1

[0026] Please see Figures 1 to 5 This embodiment provides a portable solar energy storage battery pack, including a housing 1 and a lifting rope 2. The lifting rope 2 is provided at the top of the housing 1 and is fixedly connected to the housing 1. A base 5 is installed inside the housing 1. A lower placement frame 9 is provided at the top of the base 5. Multiple sets of equally spaced limiting posts 12 are installed at the bottom of the lower placement frame 9. Multiple sets of equally spaced limiting holes 11 are provided on the surface of the base 5. The limiting posts 12 can be inserted into the limiting holes 11 and slidably connected to the limiting holes 11. Multiple sets of equally spaced battery bodies 8 are provided at the top of the lower placement frame 9. Two sets of plug-in seats 6 are symmetrically installed on the side wall of the lower placement frame 9. An upper placement frame 10 is provided above the lower placement frame 9. Two sets of vertical rods 7 are symmetrically installed on the side wall of the upper placement frame 10.

[0027] Inside the boxes 1 on both sides of the lower placement frame 9, there are clamping plates 4. On the side of the clamping plates 4 near the box 1, there are multiple sets of first springs 3 at equal intervals, and the first springs 3 are fixedly connected to the box 1.

[0028] The bottom of each vertical rod 7 is equipped with a plug post 13, and the plug post 13 can be inserted into the interior of the plug seat 6 and slidably connected to the plug seat 6. Each plug seat 6 is provided with a limit ring 15 on its side wall, and the limit ring 15 is fixedly connected to the plug seat 6.

[0029] Each limiting ring 15 has a pull-out post 14 inside, and the pull-out post 14 is slidably connected to the limiting ring 15. Each pull-out post 14 has a second spring 16 on its surface, and the two ends of the second spring 16 are respectively connected to the pull-out post 14 and the limiting ring 15.

[0030] The surface of each plug post 13 is provided with a limiting groove 17, and the pull-out post 14 can be inserted into the limiting groove 17 and slidably connected with the limiting groove 17.

[0031] Multiple battery bodies 8 are arranged and installed on the surface of the lower placement frame 9. Then, the upper placement frame 10 is aligned with the battery body 8 and pressed down so that it presses against the upper surface of the battery body 8. At the same time, the upper placement frame 10 drives the vertical rod 7 to move downward, and the vertical rod 7 drives the insertion post 13 to be inserted into the insertion seat 6. The insertion post 13 drives the pull-out post 14 to move outward inside the limiting ring 15. The pull-out post 14 compresses the second spring 16. When the limiting groove 17 moves to the position of the pull-out post 14, under the elastic cooperation of the second spring 16, the second spring 16 drives the pull-out post 14 to return to its original position, so that the pull-out post 14 is inserted into the limiting groove 17, thereby completing the fixed connection between the insertion post 13 and the insertion seat 6. With the cooperation of multiple sets of insertion posts 13 and insertion seats 6, the upper placement frame 10 and the lower placement frame 9 are connected. Then, the positive and negative terminals of the battery body 8 are connected in series or in parallel to form a lithium iron phosphate battery. To install the battery pack, take the battery pack, open the housing 1, align the limiting post 12 with the limiting hole 11, and place the battery pack on the base 5. The limiting post 12 and the limiting hole 11 work together to prevent the battery pack from shaking. Simultaneously, as the battery pack moves, it causes the clamping plate 4 to move, which in turn compresses the first spring 3. The first spring 3 provides a counterforce to the clamping plate 4, thus squeezing and limiting the battery pack from both sides to ensure its stability during use. When the device needs to be carried, pull the lifting rope 2 to take it to the desired position. Connect the device to the solar power generation equipment via the positive and negative terminal connecting posts on the surface of the housing 1 to store solar energy. This allows for convenient insertion, limiting, and fixing of the battery pack, facilitating multiple limiting and anti-shaking measures, improving stability and portability.

[0032] Work steps

[0033] Multiple battery bodies 8 are arranged and installed on the surface of the lower placement frame 9. Then, the upper placement frame 10 is aligned with the battery body 8 and pressed down so that it presses against the upper surface of the battery body 8. At the same time, the upper placement frame 10 drives the vertical rod 7 to move downward, and the vertical rod 7 drives the insertion post 13 to be inserted into the insertion seat 6. The insertion post 13 drives the pull-out post 14 to move outward inside the limiting ring 15. The pull-out post 14 compresses the second spring 16. When the limiting groove 17 moves to the position of the pull-out post 14, under the elastic cooperation of the second spring 16, the second spring 16 drives the pull-out post 14 to return to its original position, so that the pull-out post 14 is inserted into the limiting groove 17, thereby completing the fixed connection between the insertion post 13 and the insertion seat 6. With the cooperation of multiple sets of insertion posts 13 and insertion seats 6, the upper placement frame 10 and the lower placement frame 9 are connected. Then, the positive and negative terminals of the battery body 8 are connected. The battery packs are connected in series or parallel to form a lithium iron phosphate battery pack. Take the battery pack, open the housing 1, align the limiting post 12 with the limiting hole 11, and place the battery pack on the base 5. The limiting post 12 and the limiting hole 11 work together to prevent the battery pack from shaking. Simultaneously, the battery pack moves the clamping plate 4, which compresses the first spring 3. The first spring 3 provides a counterforce to the clamping plate 4, thus squeezing and limiting the battery pack from both sides to ensure its stability during use. When the device needs to be carried, pull the lifting rope 2 to take it to the usage position. Connect it to a solar power generation device through the positive and negative terminal connecting posts on the surface of the housing 1 to store solar energy. The above describes the complete usage of the portable solar energy storage battery pack.

[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
