Description

Technical Field

[0001] This utility model relates to the field of protective equipment technology, specifically to a protective cover. Background Technology

[0002] As an important power source, batteries require effective protection for their terminals, such as electrodes, to prevent damage from collisions and friction during transportation, storage, and use, while also preventing dust and moisture from entering and affecting battery performance.

[0003] Currently, most existing battery end caps are simply clipped onto the battery end. These caps have the following problems when used:

[0004] Because the protective cover lacks a stable connection structure with the battery and relies solely on its own weight or simple buckles for fastening, it is prone to falling off during equipment vibration or handling, and cannot reliably protect the battery end. At the same time, when the battery needs to be used, the protective cover must be removed from the battery end, and the removed protective cover needs to be placed separately. If the operator is negligent, the protective cover is very easy to be missed or lost, which increases the management difficulty and cost. Utility Model Content

[0005] In view of this, the present invention provides a protective cover that can be quickly and conveniently disassembled by means of an elastic element in combination with a rotating element and a connecting element, without the need for separate storage, thus solving the problem of traditional battery end protective covers being easy to fall off and lose.

[0006] To solve the above-mentioned technical problems, this utility model provides a protective cover, including a protective cover that is fastened to the end of the battery. A fixing plate is provided on the outside of the battery or on the battery mounting base. A rotating component is rotatably mounted on the fixing plate. An elastic component is provided on the upper part of the rotating component. A connecting component is provided on the upper part of the elastic component. The connecting component is fixed to the outer wall of the protective cover. This utility model can achieve efficient protection of the end of the battery by means of the protective cover under the action of the elastic component. Moreover, it is easy to remove and use without separate storage. This solves the problem that traditional protective covers are simply fastened to the end of the battery. When they are removed, they often need to be stored separately. With the extension of the usage time and the negligence of the operators, they are often easily missed or lost, which is troublesome to manage.

[0007] The fixed plate has a rotating hole, and the rotating component includes a rotating shaft that is rotatably disposed in the rotating hole. The lower part of the elastic component is disposed on the upper part of the rotating shaft. This utility model can achieve quick disassembly and installation of the protective cover on the upper part of the elastic component by the rotation of the rotating shaft in the rotating hole in conjunction with the elastic component, making the operation more convenient.

[0008] The elastic element includes a fixed cylinder located on the upper part of the rotating shaft, a spring inside the fixed cylinder, a push rod located on the upper part of the spring, and a connecting piece located on the upper part of the push rod. This utility model can stretch the spring by pulling the push rod upwards, thereby removing the protective cover on the upper part of the battery. Moreover, due to the tension of the spring, it also facilitates the easier installation of the protective cover.

[0009] The connector is a connecting plate, which is welded or bonded to the outer wall of the protective cover.

[0010] The upper part of the connecting plate is equipped with a handle, which makes it easy for the operator to grasp and remove the sealing cover.

[0011] The inner side of the protective cover is equipped with a protective pad, which should be made of foam pearl sponge to facilitate effective protection of the battery end.

[0012] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0013] 1. This utility model connects the protective cover to the battery or battery mounting base by setting a fixed plate, a rotating part, an elastic part and a connecting part. When the protective cover is removed from the battery end, it does not need to be placed separately, which effectively avoids the problem of omission and loss caused by separate placement of the protective cover, and reduces management difficulty and cost.

[0014] 2. This utility model utilizes the elasticity of the elastic element, combined with the rotation function of the rotating element, to make the installation and removal of the protective cover more convenient and labor-saving. Operators can easily pull the protective cover using the handle, and the elastic force of the elastic element enables the cover to be quickly fastened and opened, greatly improving work efficiency.

[0015] 3. This utility model can effectively buffer the impact of external forces on the battery end through the foam pearl sponge pad set on the inner side of the protective cover. At the same time, it can prevent dust, moisture and other substances from entering the battery end, thus playing a good protective role for the battery end and extending the battery's service life.

[0016] 4. This utility model allows the rotating shaft of the rotating component to rotate within the rotating hole of the fixed plate. Combined with the extension and retraction of the elastic component, the protective cover can be freely rotated to a suitable position after opening, without hindering the use of the battery, thus further improving the practicality of the device.

A connector 500 is provided on the upper part of the elastic member 400. The connector 500 is fixed together with the outer wall of the protective cover 100. This utility model can achieve convenient and quick efficient protection of the end of the battery through the protective cover 100 under the action of the elastic member 400. Moreover, it is easy to remove and use without separate storage. This solves the problem that the traditional protective cover 100 is simply fastened to the end of the battery. When it is removed, it often needs to be placed separately. With the extension of the usage time and the negligence of the operator, it is often easily missed or lost, which is troublesome to manage.

[0023] According to one embodiment of the present invention, such as Figure 1-2As shown, the fixed plate 200 has a rotating hole 201. The rotating component 300 includes a rotating shaft 301 rotatably disposed in the rotating hole 201. The rotating shaft 301 is made of 45# steel, which has high strength and wear resistance, ensuring the stability and service life of the rotating shaft 301 during rotation. The lower part of the elastic component 400 is disposed on the upper part of the rotating shaft 301. This utility model can achieve quick disassembly and installation of the protective cover 100 on the upper part of the elastic component 400 by the rotation of the rotating shaft 301 in the rotating hole 201 in conjunction with the elastic component 400, making the operation more convenient.

[0024] According to another embodiment of the present invention, such as Figure 1 and Figure 3 As shown, the elastic element 400 includes a fixed cylinder 401 disposed on the upper part of the rotating shaft 301. The fixed cylinder 401 is made of aluminum alloy, which is lightweight, high-strength, and corrosion-resistant, making it suitable as the material for the fixed cylinder 401. A spring 402 is disposed inside the fixed cylinder 401. The spring 402 is made of 65Mn spring steel, which has good elasticity and toughness, meeting the functional requirements of the elastic element 400. A push rod 403 is disposed on the upper part of the spring 402. The push rod 403 is made of stainless steel, which is corrosion-resistant and has high strength, ensuring the service life of the push rod 403. A connecting piece 500 is disposed on the upper part of the push rod 403. This utility model can stretch the spring 402 by pulling the push rod 403 upward, thereby removing the protective cover 100 on the upper part of the battery. Moreover, due to the pulling force of the spring 402, it is also easier to assist in the installation of the protective cover 100.

[0025] Connector 500 is a connecting plate made of galvanized steel sheet. Galvanized steel sheet has good corrosion resistance and strength, ensuring the stability of the connecting plate. The connecting plate is welded or bonded to the outer wall of the protective cover 100.

[0026] The upper part of the connecting plate is equipped with a handle 600. The handle 600 is made of engineering plastic. Engineering plastic is lightweight, comfortable to hold, and has a certain strength, making it easy for the operator to grip. The handle 600 makes it easy for the operator to grasp and remove the sealing cover.

[0027] The inner side of the protective cover 100 is provided with a protective pad 700. The protective pad 700 should be a foam pearl sponge pad. The foam pearl sponge pad has good cushioning performance and can effectively protect the battery end and reduce the impact of external force on the battery. This makes it easy to achieve effective protection of the battery end.

[0028] How to use this utility model:

[0029] First, it needs to be clarified that this utility model mainly involves the protection of the battery end. This utility model will be explained in detail using the protection principle and usage method of the end protection process of a cylindrical solid-state battery as an example. The working principle is as follows:

[0030] The battery end protective cover 100 of this utility model achieves protection of the battery end and convenient operation during operation through the following methods:

[0031] Protective connection principle: The protective cover 100 is connected to the fixing plate 200 through the connecting plate, the top rod 403, the spring 402, the fixing cylinder 401 and the rotating shaft 301. The fixing plate 200 is fixed to the outside of the battery or the battery mounting base, so that the protective cover 100 is always connected to the battery or its mounting base, avoiding the problem of loss caused by the protective cover 100 being placed alone after being removed.

[0032] Elastic opening and closing principle: When the protective cover 100 needs to be opened, the operator pulls the handle 600 upwards. The handle 600 drives the push rod 403 upwards via the connecting plate. The push rod 403 compresses the spring 402, causing the protective cover 100 to detach from the battery end. Then, under the rotation of the rotating shaft 301, the protective cover 100 can be rotated to a position that does not affect the use of the battery. When the protective cover 100 needs to be closed, rotate the protective cover 100 above the battery end, release the handle 600, and under the elastic restoring force of the spring 402, the push rod 403 pushes the connecting plate and the protective cover 100 downwards, so that the protective cover 100 is tightly fastened to the battery end, achieving protection of the battery end.

[0033] Buffer protection principle: The foam pearl sponge pad 700 inside the protective cover 100 is in close contact with the battery end when the protective cover 100 is fastened to the battery end. When subjected to external impact, the foam pearl sponge pad can absorb and buffer the impact force, reduce damage to the battery end, and prevent dust, moisture and other substances from entering the battery end.

[0034] The usage method is as follows:

[0035] Installation device: First, fix the fixing plate 200 to the outside of the battery or the battery mounting base by means of bolts, then rotate the shaft 301 into the rotating hole 201 of the fixing plate 200, assemble the fixing cylinder 401, spring 402 and top rod 403 in sequence, and finally fix the connecting plate to the protective cover 100 and connect the connecting plate to the top rod 403 to complete the installation of the entire device.

[0036] Close the protective cover 100: Align the protective cover 100 with the end of the battery. Under the elastic action of the spring 402, push the top rod 403, the connecting plate and the protective cover 100 downward, so that the protective cover 100 is tightly fastened to the end of the battery. At this time, the foam pearl sponge pad on the inside of the protective cover 100 contacts the end of the battery to achieve protection.

[0037] To open the protective cover 100: The operator grabs the handle 600 and pulls it upward. The handle 600 moves the connecting plate and the push rod 403 upward. The push rod 403 compresses the spring 402, causing the protective cover 100 to detach from the battery end. Then, the protective cover 100 is rotated around the pivot 301 until it is in a position that does not affect the use of the battery, and the battery can then be operated.

[0038] Close the protective cover 100 again: After the battery is used up, rotate the protective cover 100 back to the top of the battery end, release the handle 600, and under the elastic restoring force of the spring 402, the protective cover 100 will automatically move down and fasten to the battery end, completing the second protection.

[0039] This invention enables quick and convenient disassembly of the protective cover 100 through the action of the elastic element 400, the rotating element 300, and the connecting element 500, without the need for separate storage. This solves the problem of traditional battery end protective covers 100 being easy to fall off and lose.

[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
