In addition, as one of ordinary skill in the art can appreciate, with technical development and new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.
In the description of the present application, it is to be understood that all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs unless defined otherwise. Furthermore, any terminology used is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.
In addition, numerous specific details are set forth in the following detailed description in order to provide a better understanding of the present application. It will be understood by those skilled in the art that the present application may be practiced without some of these specific details. In some instances, methods, means, elements, and circuits have not been described in detail as not to unnecessarily obscure the present application.
The technical scheme of the utility model is further described below by the specific embodiments with reference to the accompanying drawings.
Example 1
Referring to fig. 1 to 4, an embodiment of the present utility model provides a battery, including a battery body 1 and an insulating protection sleeve 2; wherein,
the insulating protective sleeve 2 is coated on the outer surface of the battery body 1 and is made of hard materials and comprises an insulating sleeve shell 21 and an insulating sealing plate 22;
the insulating casing 21 is provided with an opening and a containing cavity communicated with the opening, and the battery body 1 is positioned in the containing cavity;
the insulating sealing plate 22 is disposed at the opening and movably inserted into the insulating housing 21 to close the opening.
It should be noted that, as mentioned in the background art, the existing insulation protection film has low protection strength, because it is limited by the characteristics of two manufacturing materials, namely, the PET substrate and glue, so that the manufactured insulation protection film is thin and soft and cannot play a good role in protection, and aiming at the problem, this embodiment proposes an improvement scheme for the manufacturing material, that is, in this embodiment, the manufacturing material of the insulation protection sleeve 2 is not the PET substrate and glue, but is a hard material, such as PC (Polycarbonate), PP (Polypropylene) and other plastics with a little thicker and a little harder texture, so that the insulation protection sleeve 2 has enough strength to cover and protect the battery body 1, and appearance defects such as wrinkles, bubbles, impressions, scratches and the like on the surface of the battery body 1 can be avoided.
In addition, the existing battery is poor in appearance, so that the adhered insulating film can be torn off for re-coating during processing, however, the adhered insulating film is difficult to remove cleanly, the appearance of the battery can be affected, and the production efficiency is greatly reduced. In order to reduce the process difficulty and improve the production efficiency during the machining, the structure of the insulating protective sleeve 2 is further specially designed, in this embodiment, the insulating protective sleeve 2 is not an integrated design, but a split design, which specifically comprises two parts, namely, an insulating sleeve shell 21 and an insulating sealing plate 22, and the insulating sleeve shell 21 and the insulating sealing plate 22 are in a movable plug-in matching relationship, so that the assembly is simple and easy, and the battery body can be separated from the insulating protective sleeve more conveniently during the disassembly.
It will be appreciated that when the insulating protective cover 2 is wrapped on the outer surface of the battery body 1, the bottom surface of the battery body 1 is in contact with the insulating sealing plate 22, i.e. is placed on the insulating sealing plate 22, while the side surfaces and the top surface of the battery body 1 are located in the insulating jacket 21, in other words, the insulating protective cover 2 wraps the entire battery body 1 from top to bottom from the top surface of the battery body 1, and is integrally connected with the insulating sealing plate 22.
In the original protection scheme of the insulating film, the top cover of the battery is also required to be attached with the top cover patch for insulation protection, but in the embodiment, since the insulating sleeve shell 21 not only covers the side surface of the battery body 1, but also covers the top surface of the battery body 1 at the same time, the insulating sleeve shell 21 can realize insulation protection on the side surface of the battery body 1, namely replace the existing insulating protection film, and can realize insulation protection on the top surface (particularly to the top cover) of the battery body 1, namely replace the existing top cover patch, thereby canceling the existing top cover patch.
In addition, for the specific structural design of the battery body 1, for example, the specific structural design includes a casing, a battery core, an electrolyte, etc., the specific functions of the structural designs are to ensure that each function of the battery body 1 works normally, and in view of the fact that the structural designs are implemented in the prior art, they are not the focus of the design of the embodiment, and are not further described herein.
The insulating sleeve 21 and insulating closing plate 22 have a thickness of 0.1mm-0.3mm, for example. Wherein, even if the thickness of the insulating sheath 21 and the insulating sealing plate 22 is taken to be 0.1mm, the thickness is consistent with the thickness of the existing insulating film, the protective strength is higher because the textures of the insulating sheath 21 and the insulating sealing plate 22 are harder. The inventors have found through practical verification that setting the thickness of the insulating jacket 21 and the insulating cover plate 22 within the above-described interval works best, and that exceeding 0.3mm in thickness increases the weight of the battery.
In this embodiment, the surface of the insulating casing 21 corresponding to the top cover of the battery body 1 is provided with a positive electrode post avoiding hole for exposing the positive electrode post and a negative electrode post avoiding hole for exposing the negative electrode post.
It should be noted that, in this embodiment, the existing top cover patch is omitted, and the insulating casing 21 is used to realize insulating protection on the top cover of the battery body 1, and accordingly, the insulating casing 21 corresponds to the surface of the top cover of the battery body 1, that is, the top surface is provided with a positive electrode post avoiding hole and a negative electrode post avoiding hole, so as to expose the positive electrode post and the negative electrode post.
In this embodiment, a positive electrode mark is formed on the insulating sleeve 21 at a position close to the positive electrode post avoiding hole;
a negative electrode mark is formed on the insulating sleeve 21 at a position close to the negative electrode post avoiding hole.
It should be noted that, the positive electrode mark and the negative electrode mark on the insulating sleeve 21 can be conveniently and rapidly identified by personnel, is simple and efficient, and meanwhile, the battery short circuit caused by wrong connection of the positive electrode and the negative electrode is avoided, so that the thermal runaway of the lithium ion battery is avoided.
In this embodiment, the positive electrode label and the negative electrode label are formed by any one of coating, printing, attaching, and punching.
If the positive electrode mark and the negative electrode mark are formed by any one of coating, printing and attaching, the colors of the positive electrode mark and the negative electrode mark can be different, so that personnel can be helped to distinguish the positive electrode mark and the negative electrode mark more quickly.
In the present embodiment, the insulating casing 21 is provided with an explosion-proof valve escape hole for exposing the explosion-proof valve, corresponding to the surface of the explosion-proof valve of the battery body 1.
The insulating sleeve 21 covers the side surface of the battery body 1 and the top surface of the battery body 1, so that the explosion-proof valve is arranged on the top cover of the battery body 1 or the side surface shell of the battery body 1, and the explosion-proof valve avoiding hole is arranged at the corresponding position on the insulating sleeve 21 to expose the explosion-proof valve.
In the present embodiment, an adhesive layer is attached to the surface of the insulating sealing plate 22 that contacts the battery body 1;
the insulating sealing plate 22 is bonded and fixed to the battery body 1 by an adhesive layer.
In order to avoid that the battery body 1 located in the insulating protection sleeve 2 collides with the inner wall of the insulating protection sleeve 2 due to shaking, in this embodiment, a glue layer is attached to the surface of the insulating sealing plate 22 contacting with the battery body 1, and the bottom of the battery body 1 and the insulating sealing plate 22 can be bonded together by the glue layer, so as to avoid or reduce the shaking amplitude of the battery body 1.
In this embodiment, there are various embodiments of the movable plug-in connection between the insulating jacket 21 and the insulating sealing plate 22, and two of them will be described in the following.
Referring to fig. 1-2 again, in one embodiment, the shell wall of the insulating sleeve 21 is recessed toward the end face of the insulating sealing plate 22 (i.e., the a-face in fig. 2) in a direction away from the insulating sealing plate 22 (i.e., the arrow direction in fig. 2) to form a plugging hole 23;
the edge of the insulating sealing plate 22 is provided with a plugging part 24 matched with the plugging hole 23 at a position corresponding to the plugging hole 23;
the insertion holes 23 may be formed on the entire end surface of the wall of the insulating housing 21, or the insertion holes 23 may be formed on a part of the end surface of the wall of the insulating housing 21. Similarly, the insulating sealing plate 22 may be provided with the plugging portion 24 on the entire edge, or may be provided with the plugging portion 24 on a portion of the edge of the insulating sealing plate 22.
In addition, in order to improve the stability of the movable plug connection between the insulating sleeve shell 21 and the insulating sealing plate 22, a clamping protrusion may be provided in the plug hole 23, and a clamping groove may be correspondingly provided in the plug portion 24, or a clamping groove may be provided in the plug hole 23, and a clamping protrusion may be correspondingly provided in the plug portion 24, so as to achieve the purpose that the insulating sleeve shell 21 and the insulating sealing plate 22 can be separated only by slightly applying force.
Referring again to fig. 3-4, in another embodiment, the inner side of the shell wall (i.e., the b-plane in fig. 4) of the insulating sleeve 21 is concavely formed with a plugging slot 25 along the direction from the inner side to the outer side of the shell wall (i.e., the arrow direction in fig. 4);
the edge of the insulating sealing plate 22 is provided with a plugging portion 24 matched with the plugging groove 25 at a position corresponding to the plugging groove 25.
The insertion holes 23 may be formed in the entire inner wall of the insulating jacket 21, or the insertion holes 23 may be formed in a part of the inner wall of the insulating jacket 21. Similarly, the insulating sealing plate 22 may be provided with the plugging portion 24 on the entire edge, or may be provided with the plugging portion 24 on a portion of the edge of the insulating sealing plate 22.
In addition, in order to improve the stability of the movable plug connection between the insulating sleeve shell 21 and the insulating sealing plate 22, a clamping protrusion may be provided in the plug connection groove 25, and a clamping groove may be correspondingly provided in the plug connection portion 24, or a clamping groove may be provided in the plug connection groove 25, and a clamping protrusion may be correspondingly provided in the plug connection portion 24, so as to achieve the purpose that the insulating sleeve shell 21 and the insulating sealing plate 22 can be separated only by slightly applying force.
