Description

Technical Field

[0001] This utility model relates to the field of photovoltaic energy storage technology, and in particular to a series safety lock for photovoltaic energy storage battery packs. Background Technology

[0002] The photovoltaic energy storage battery pack series safety lock is a key component used in photovoltaic energy storage systems to realize the electrical connection and mechanical fixation between battery pack modules. Through a specially designed lock structure, it can ensure that the battery packs are tightly and stably connected during the series connection process, and has the functions of preventing loosening and falling off, ensuring the stability and safety of the connection between battery packs.

[0003] In the series connection process of photovoltaic energy storage systems, the battery packs to be connected in series must first be stacked, and then connected by wires to complete the series connection. During subsequent handling, if the stacked battery packs are tilted, misalignment and loosening of the battery units can easily occur, leading to poor contact at the wire connection points. This situation not only increases the circuit contact resistance, causing safety hazards such as localized overheating, but also affects the overall performance and operational stability of the battery pack, increasing the risk of system failure. Utility Model Content

[0004] The purpose of this invention is to solve the problem that during subsequent handling, when the stacked and connected battery packs are tilted, misalignment and loosening of the battery pack units can easily occur, leading to poor contact at the wire connection points. Therefore, this invention proposes a series safety lock for photovoltaic energy storage battery packs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a series safety lock for photovoltaic energy storage battery packs, including a positioning base plate, a plurality of energy storage battery bodies are arranged on the top of the positioning base plate, the plurality of energy storage battery bodies are stacked on top of each other, a locator is fixedly installed on the outer side of the plurality of energy storage battery bodies in a centrally symmetrical manner, a positioning rod is movably inserted through the inside of the locator, a pressure plate is fixedly connected to one end of the positioning rod, a hook is fixedly installed symmetrically on one side of the pressure plate, and a buckle is fixedly installed on the top of the energy storage battery body in a centrally symmetrical manner.

[0006] Preferably, the top of the energy storage battery body is symmetrically fixedly connected with positioning protrusions, and the bottom of the energy storage battery body is provided with positioning slots, so that the positioning protrusions at the top of one energy storage battery body can be movably engaged with the positioning slots at the bottom of another energy storage battery body.

[0007] Preferably, a positioning groove is provided on one side of the positioning protrusion, and the pressure plate is set inside the positioning groove.

[0008] Preferably, a positioning groove is provided on one side of the positioning protrusion, and the pressure plate is set inside the positioning groove.

[0009] Preferably, a positioning cylinder is fixedly installed at the edge of the positioning base plate in a centrally symmetrical manner, and the other end of the positioning rod moves through the interior of the positioning cylinder.

[0010] Preferably, rounded rectangular grooves are provided on both sides of the main body of the energy storage battery.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the locking process is completed by the interlocking of buckles and hooks. Through this operation, the energy storage battery pack can maintain the relative position stability between the main battery cells during transportation, even if it encounters tilting, vibration or other working conditions, effectively avoiding the risk of misalignment or loosening, and providing a solid guarantee for the safe and reliable operation of the energy storage system.

[0013] 2. In this utility model, by fixing the buckle inside the second mounting groove and recessing the buckle into the positioning protrusion, the buckle is prevented from deforming or being damaged due to external pressure while ensuring the strength of the mechanical connection, thus extending the service life of the safety lock. The design of placing the pressure plate in the first positioning groove makes the contact between the pressure plate and the battery body more intimate and the pressure distribution more uniform. This prevents the pressure plate from sliding and reduces wear on the surface of the battery body. Attached Figure Description

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-5 As shown, this utility model provides a series safety lock for photovoltaic energy storage battery packs, including a positioning base plate 1. A plurality of energy storage battery bodies 2 are arranged on top of the positioning base plate 1, stacked on top of each other. Positioners 21 are fixedly installed on the outer sides of the plurality of energy storage battery bodies 2 in a centrally symmetrical manner. A positioning rod 22 is movably inserted through the interior of the positioning rod 21. A pressure plate 23 is fixedly connected to one end of the positioning rod 22. Hooks 24 are symmetrically fixedly installed on one side of the pressure plate 23. The top of the energy storage battery bodies 2 are centrally symmetrically... The battery body 2 is fixedly installed with a buckle 25. The top of the battery body 2 is symmetrically fixedly connected with a positioning protrusion 26. The bottom of the battery body 2 is provided with a positioning slot 27. The positioning protrusion 26 at the top of one battery body 2 is movably engaged with the positioning slot 27 at the bottom of another battery body 2. The positioning base plate 1 is fixedly installed with a positioning cylinder 11 in a centrally symmetrical manner at the edge. The other end of the positioning rod 22 moves through the interior of the positioning cylinder 11. Rounded rectangular slots 28 are provided on both sides of the battery body 2.

[0023] The specific setup and function of this embodiment are described below. First, multiple energy storage battery bodies 2 are stacked and arranged in a layered manner. Precise positioning is achieved through structural cooperation, that is, the positioning protrusion 26 of the upper battery body must be precisely embedded into the positioning slot 27 at the bottom of the lower battery body to form a stable mechanical positioning structure. Then, one end of the positioning rod 22 passes through the locator 21 and penetrates into the positioning cylinder 11, while the pressure plate 23 is pressed tightly against the surface of the top energy storage battery body 2 to form axial constraint. Finally, the locking process is completed by the mutual engagement of the buckle 25 and the hook 24. Through this operation, the energy storage battery pack can maintain the relative position stability between the battery bodies during transportation, even if it encounters tilting, vibration, or other conditions, effectively avoiding the risk of misalignment and loosening, and providing a solid guarantee for the safe and reliable operation of the energy storage system.

[0024] Example 2: Figures 1-5As shown, the photovoltaic energy storage battery pack series safety lock of this utility model includes a positioning base plate 1. Several energy storage battery bodies 2 are arranged on top of the positioning base plate 1, stacked on top of each other. Positioners 21 are fixedly installed on the outer sides of the several energy storage battery bodies 2 in a centrally symmetrical manner. A positioning rod 22 is movably inserted through the interior of the positioning rod 21. A pressure plate 23 is fixedly connected to one end of the positioning rod 22. Hooks 24 are symmetrically fixedly installed on one side of the pressure plate 23. A locking hook is fixedly installed on the top of the energy storage battery body 2 in a centrally symmetrical manner. The buckle 25 and the positioning protrusion 26 have a first positioning groove 261 on one side. The pressure plate 23 is set inside the first positioning groove 261. The first positioning groove 261 is also symmetrically provided with second mounting grooves 262 on both sides. The buckle 25 is fixedly installed inside the second mounting groove 262. The top of the energy storage battery body 2 is symmetrically fixedly connected with the positioning protrusion 26. The bottom of the energy storage battery body 2 is provided with a positioning slot 27. The positioning protrusion 26 at the top of one energy storage battery body 2 is movably engaged with the positioning slot 27 at the bottom of another energy storage battery body 2.

[0025] The overall effect of this embodiment is that by fixing the buckle 25 inside the second mounting groove 262, the buckle 25 is recessed into the positioning protrusion 26. This ensures the mechanical connection strength while preventing the buckle 25 from deforming or being damaged due to external pressure, thus extending the service life of the safety lock. The design of placing the pressure plate 23 in the first positioning groove 261 makes the contact between the pressure plate 23 and the battery body more intimate and the pressure distribution more uniform. This prevents the pressure plate 23 from sliding while reducing wear on the surface of the battery body.

[0026] The usage and working principle of this device are as follows: First, multiple energy storage battery bodies 2 are stacked and arranged in a layered manner. Precise positioning is achieved through structural cooperation, that is, the positioning protrusion 26 of the upper battery body must be precisely embedded into the positioning slot 27 at the bottom of the lower battery body to form a stable mechanical positioning structure. Then, one end of the positioning rod 22 is passed through the positioner 21 and inserted into the positioning cylinder 11, while the pressure plate 23 is pressed tightly against the surface of the top energy storage battery body 2 to form axial constraint. Finally, the locking process is completed by the mutual engagement of the buckle 25 and the hook 24.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
