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; they can refer to the internal connection of two components. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood through the specific circumstances.

[0037] The technical solution of this utility model will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0038] See Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 This utility model provides an insulating tape for lithium-ion batteries, comprising:

[0039] Tape ring 1, with connecting ring 2 fastened to the outside of tape ring 1, and lithium battery insulating tape body 3 wrapped around connecting ring 2. It should be noted that lithium battery insulating tape body 3 is composed of base tape and pressure-sensitive adhesive layer. The base tape is generally made of cotton cloth, synthetic fiber fabric and plastic film, etc., and the adhesive layer is made of rubber and tackifying resin and other compounding agents. It has good adhesion and excellent insulation performance. This is existing technology and will not be described in detail here.

[0040] The tape ring 1 is detachably connected to a cutting and assembly mechanism 4. It should be noted that the cutting and assembly mechanism 4 makes it convenient to cut the insulating tape when using it, without the need to find other cutting tools, which is also healthier and more hygienic. Moreover, it can be well protected when not in use.

[0041] The cutting and assembly mechanism 4 includes a disc 41, a vertical plate 44, a rotating shaft 45, a horizontal bar 46, a cutting blade 47, a limiting bar 48, and a T-block 49;

[0042] The upright plate 44 is fixedly installed on the disc 41, the rotating shaft 45 is rotatably installed on the upright plate 44, the end of the rotating shaft 45 is fixedly connected to the horizontal bar 46, and the cutting blade 47 is fixedly installed at the bottom of the horizontal bar 46. It should be noted that the insulating tape is cut in this way.

[0043] T-block 49 is fixedly installed on the top of vertical plate 44, and limiting strip 48 is slidably sleeved on the outside of T-block 49. The bottom of limiting strip 48 abuts against horizontal strip 46, and a protective groove 481 is provided on limiting strip 48.

[0044] After the lithium battery insulating tape 3 is adhered to the lithium battery through the cutting and assembly mechanism 4, the tape loop 1 is pulled upwards so that the lithium battery insulating tape 3 comes into contact with the cutting blade 47 for cutting. This facilitates the cutting of the insulating tape without the need to find other cutting tools. When not in use, the limiting strip 48 can be pulled to separate the limiting strip 48 from the top of the horizontal strip 46. Then, the horizontal strip 46 can be rotated 180° to push the limiting strip 48 back. The bottom of the limiting strip 48 continues to limit the horizontal strip 46, so that the protective groove 481 on the limiting strip 48 protects the cutting blade 47 and prevents accidental contact with the cutting blade 47 from causing damage.

[0045] Specifically, the tape ring 1 includes an outer ring 11, a connecting rod 12, an inner ring 13, a sleeve 14, a positioning rod 15, and a connector 16. The connecting rod 12 is fixedly installed between the outer ring 11 and the inner ring 13. The sleeve 14 is slidably sleeved on the outside of the connecting rod 12. The positioning rod 15 is fixedly connected to the sleeve 14 and is engaged with the connecting ring 2. The connector 16 is fixedly installed on the inner ring 13.

[0046] After the lithium battery insulating tape 3 on a connecting ring 2 is used up using the tape ring 1, first remove the cutting and assembly mechanism 4 to release the limit on the sleeve 14, then pull the sleeve 14 to move the positioning rod 15 out of the positioning groove, release the limit on the connecting ring 2, and then replace it.

[0047] Specifically, the cutting and assembly mechanism 4 also includes a plug rod 411 and a locking screw 42. The plug rod 411 is fixedly installed on the disc 41. The sleeve 14 has a slot, and the plug rod 411 is engaged with the slot. The locking screw 42 is threadedly installed on the disc 41 and threadedly connected to the connector 16. The disc 41 has a circular groove 43.

[0048] By rotating the locking screw 42 through the above-mentioned cutting and assembly mechanism 4, the locking screw 42 is separated from the connecting piece 16. Then, by pulling the disc 41, the cutting and assembly mechanism 4 can be quickly disassembled, which facilitates the maintenance of the cutting blade 47.

[0049] Specifically, a damping pad is embedded at the top of the limiting strip 48, and two long T-shaped grooves are opened on the side of the limiting strip 48. The T-shaped block 49 contacts the inner wall of the long T-shaped groove, and the damping pad abuts against the inner wall at the top of the long T-shaped groove. It should be noted that the damping pad can apply a certain friction force to the limiting strip 48, so that the limiting strip 48 can remain stable when it moves to a certain position.

[0050] Specifically, a movable hole is provided on the outer ring 11, and the positioning rod 15 is vertically slidably installed in the movable hole. A positioning groove is provided on the connecting ring 2, and the positioning rod 15 is engaged with the positioning groove. It should be noted that this facilitates the limiting treatment of the connecting ring 2.

[0051] Specifically, the cutting blade 47 is located above the lithium battery insulating tape body 3, the bottom of the limiting strip 48 is in contact with the upright plate 44, and the side of the upright plate 44 is in contact with the horizontal strip 46. It should be noted that the positions of the limiting strip 48 and the upright plate 44 can be limited to facilitate subsequent rotation protection of the cutting blade 47.

[0052] Working principle:

[0053] S1: After adhering the lithium battery insulating tape 3 to the lithium battery, pull the tape loop 1 upward so that the lithium battery insulating tape 3 comes into contact with the cutting blade 47 for cutting. This makes it convenient to cut the insulating tape without needing to find other cutting tools, and it is also healthier and more hygienic.

[0054] S2: When not in use, the limiting strip 48 can be pulled to separate the limiting strip 48 from the top of the horizontal strip 46. Then, the horizontal strip 46 can be rotated 180° to rotate the cutting blade 47 to the top. Then, the limiting strip 48 can be pushed back. The bottom of the limiting strip 48 continues to limit the horizontal strip 46, so that the protective groove 481 on the limiting strip 48 protects the cutting blade 47 and prevents accidental contact with the cutting blade 47 from causing damage, thus achieving a good protective effect.

[0055] S3: Multiple connecting rings 2 wrapped with lithium battery insulating tape 3 can be prepared in advance. After the lithium battery insulating tape 3 on one connecting ring 2 is used up, rotate the locking screw 42 to separate the locking screw 42 from the connector 16. Then pull the disc 41 to quickly disassemble the cutting and assembly mechanism 4, so that the insertion rod 411 moves out of the sleeve 14, releasing the limitation on the sleeve 14. Then pull the sleeve 14 to move the positioning rod 15 out of the positioning groove, releasing the limitation on the connecting ring 2. Then the connecting ring 2 can be replaced. It is quite convenient to use.

[0056] The above provides a detailed description of an insulating tape for lithium-ion batteries provided by this utility model. Specific embodiments have been used to illustrate the principles and implementation methods of this utility model. The descriptions of these embodiments are merely for the purpose of helping to understand the method and core ideas of this utility model. It should be noted that those skilled in the art can make various improvements and modifications to this utility model without departing from its principles, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
