Description

Technical Field

[0001] The utility model relates to the technical field of electric energy storage equipment, and more specifically, to an electric energy storage device which is easy to assemble and use. Background Art

[0002] An electric energy storage device is a device that converts electrical energy into chemical energy, and then converts chemical energy into electrical energy when electricity is needed. Common ones in daily life include batteries, etc. A battery is a battery that can be used again after being discharged and recharged. There are lead-acid batteries, nickel-iron batteries, and nickel-cadmium batteries. The positive electrode of a lead-acid battery is lead dioxide, the negative electrode is lead, and the electrolyte is a dilute sulfuric acid solution. When discharged (used), the positive and negative electrodes react with sulfuric acid to form lead sulfate. When the concentration of the sulfuric acid solution drops to a certain level, it must be charged. When charging with an external power source, the electrodes and solution can be restored to their original state, and they can continue to be used after being charged.

[0003] Electricity is generally stored in batteries. However, common batteries are of fixed size and cannot be suitable for all workplaces. They have poor versatility. Therefore, an assembled power storage device has emerged.

[0004] At present, the common power storage devices that can be assembled and used on the market generally install multiple power storage devices in a box during the assembly process, and connect the two ends of the wires according to the positive and negative poles through wires using hot melting and other technologies to connect the multiple power storage devices, or wrap the copper wires in the wires around the bolt-structured power connection poles provided on the power storage devices, and screw the power connection poles into the power storage devices to achieve the connection of the power storage devices. However, the above-mentioned connection and assembly methods require the use of tools for assembly and disassembly when disassembly is required, and the assembly and disassembly steps are relatively cumbersome and have poor practicality.

[0005] Therefore, in order to solve the above technical problems, the present application proposes an electric energy storage device that is easy to assemble and use. Utility Model Content

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution: comprising an electric energy storage device for storing electric energy, wherein one end of the electric energy storage device is used for assembly connection as an assembly end and the other end is a load-bearing end;

[0008] It also includes a power connection slot opened at the four corners of the assembly end of the power storage device for plugging in wires for assembly and connection, a protective cover plate with positive and negative poles marked on the surface is movably installed on the top of the power connection slot, a telescopic slot is opened at the center of the bottom of the power connection slot, a pressure plate is slidably installed in the telescopic slot, a slot is opened at the bottom of the pressure plate, a plug plate is movably plugged in the slot, two ends of the surface of the plug plate are connected to the two ends of the bottom of the pressure plate by a reset spring, and wire plug holes for plugging in wires are correspondingly opened at the open end of the power connection slot, in the pressure plate and in the plug plate, and the wires are squeezed by the misalignment between the pressure plate and the plug plate and the open end of the power connection slot to clamp and fix the wires, thereby realizing the electrical connection of multiple power storage devices after assembly.

[0009] In this solution, rotating rods that can rotate and slide are fixedly installed at both ends of the bottom of the protective cover plate. The rotating rods are slidably and rotatably connected in the slide rails. The slide rails are opened at both ends of the inner side walls of the power connection slot. The top of the slide rail opened at the open end of the power connection slot is open and the bottom end is provided with a card slot upward. The slide rail opened at the open end of the power connection slot is slidably connected to the card rod, and the card rod is fixedly connected to both sides of the other end of the protective cover plate and can be removably inserted into the card slot.

[0010] In this embodiment, the protective cover is provided with a rubber sheet at the top of one end of the clamping rod corresponding to the position of the wire insertion hole opened at the top of the power connection slot, so as to clamp and fix the wires when the protective cover is closed.

[0011] It should be noted that when the pressure plate is inserted into the bottom of the telescopic slot, the corresponding wire insertion holes in the power connection slot, the pressure plate and the plug plate are offset from each other and leave connecting spaces, so that the wires can be compressed without causing excessive squeezing and dislocation to cause wire breakage.

[0012] Furthermore, the pressing plate is arranged in a right-angled trapezoidal shape and the inclined surface is fitted to the inner side of the protective cover plate, so that the pressing plate is squeezed and contracted into the telescopic groove by squeezing during the closing process of the protective cover plate.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. Convenient assembly and disassembly:

[0015] The device achieves quick connection and fixation of wires through the ingenious design of the power connection slot, pressure plate, plug plate and protective cover.

[0016] 2. Efficient electrical connection:

[0017] The pressure plate and plug plate in the power connection slot are designed with an offset design to effectively clamp the wires, ensuring that the electrical connection between the power storage devices is stable and reliable, thereby improving the power transmission efficiency.

[0018] 3. Security protection:

[0019] The protective cover is equipped with positive and negative pole markings to help connect the wires correctly and avoid safety hazards such as short circuits. At the same time, the protective cover can further clamp and fix the wires when closed, providing additional safety protection.

[0020] 4. Strong versatility:

[0021] Compared with traditional fixed-volume batteries, this power storage device adopts a modular design, which is easy to assemble according to the actual needs of the workplace, improving the versatility and flexibility of the equipment.

[0022] 5. Ingenious structure to avoid wire damage:

[0023] The design of the wire plug hole takes into account the stress conditions of the wires during the compression process. By staggering and leaving connecting space, the risk of wire breakage due to excessive squeezing is avoided, thereby extending the service life of the equipment.

[0024] 6. Easy to maintain:

[0025] Since the assembly and disassembly process is simple, when the equipment fails or requires maintenance, the problem can be quickly located and solved, reducing maintenance costs and time. BRIEF DESCRIPTION OF THE DRAWINGS

A protective cover plate 2 with positive and negative poles marked on the surface is movably installed on the top of the power connection slot 3. A telescopic slot 15 is opened at the center of the bottom of the power connection slot 3. A pressure plate 8 is slidably installed in the telescopic slot 15. A slot 13 is opened at the bottom of the pressure plate 8. A plug plate 14 is movably plugged in the slot 13. The two ends of the surface of the plug plate 14 are connected to the two ends of the bottom of the pressure plate 8 through a reset spring 12. Wire insertion holes 10 for plugging in wires are correspondingly opened at the open end of the power connection slot 3, in the pressure plate 8 and in the plug plate 14. The wires are squeezed by the misalignment between the pressure plate 8 and the plug plate 14 and the open end of the power connection slot 3, so that the wires are clamped and fixed, thereby realizing the electrical connection of multiple power storage devices 1 after assembly.

[0039] Rotating rods 11 that can rotate and slide are fixedly installed at both ends of the bottom of the protective cover 2. The rotating rod 11 is slidably and rotatably connected in the slide rail 7. The slide rail 7 is opened at both ends of the inner wall of the power connection groove 3.
