Therefore, including battery size, model, material, cover size, material, etc., these are all conventional technical means in the art. For these conventional technical means that are not within the scope of the technical solution of the present invention, the specific embodiments of the present invention do not need to change Every detail is detailed, and it is unrealistic to list them all. Obviously, the technical solution implemented by the present invention is actually a wearable battery that can be referenced and implemented by those skilled in the art in combination with conventional technical means, which is conducive to mass production. According to different application conditions and usage requirements, the technical personnel can follow The actual application and testing of the product formed by the technical scheme of the present invention can actually obtain a series of advantages brought by it, and these advantages will be gradually manifested in the following analysis of the system structure.
以下主要分为三个实施例分别解析,这三个实施例是在同一个构思基础上实施的。The following is mainly divided into three embodiments for analysis respectively, and these three embodiments are implemented on the basis of the same concept.
实施例一Example one
如图1、图2、图7所示,对于拟实施的利于促进量产化的穿戴电池结构,其首先包括用于装配电池内部电芯的壳体1,一般来说,其采用圆柱形状的金属构件,如铜、铝、钼等,其尺寸以能够容纳电芯体积为适宜;其次,所实施穿戴电池结构还包括用于与壳体1组合装配以便于将电芯密封在内部的盖体一2,对于本实施例一,所采用的盖体一2优选圆盘形状并且其与壳体1装配之后,能够确保内部穿戴电池的基本密封。当然,对于壳体1与盖体的结构,本领域技术人员也可采用诸如上盖、下盖之类的组件名称进行命名,虽然组件名称所有不同,但在发挥功能相同的前提下,可以有不同形状构造的壳体1以及盖体。As shown in Figure 1, Figure 2, Figure 7, for the proposed implementation of a wearable battery structure that facilitates mass production, it first includes a housing 1 for assembling the internal cells of the battery. Generally speaking, it adopts a cylindrical shape. Metal components, such as copper, aluminum, molybdenum, etc., whose size is suitable to accommodate the volume of the battery cell; secondly, the implemented wearable battery structure also includes a cover for assembling and assembling with the casing 1 so as to seal the battery core inside. 1-2. For the first embodiment, the adopted cover -2 is preferably in the shape of a disc, and after it is assembled with the housing 1, it can ensure the basic sealing of the battery worn inside. Of course, for the structure of the housing 1 and the cover, those skilled in the art can also use component names such as the upper cover and the lower cover for naming. Although the names of the components are different, they may The housing 1 and the cover have different shapes and structures.
对于以往装配电极组件5所采用的方式是,先让电芯装配在壳体1内部,然后再将电极组件5装配在壳体1内部,最后才能将盖体一2与壳体1进行装配密封,如此一来,内部电芯与电极组件5的位置无法确保牢固不变,更加影响加工生产装配,很多工序需要人为操作与人为检测,无法促进量产化。For the previous method of assembling the electrode assembly 5, the battery core is assembled inside the housing 1, and then the electrode assembly 5 is assembled inside the housing 1, and finally the cover 2 and the housing 1 can be assembled and sealed. As a result, the position of the internal battery core and the electrode assembly 5 cannot be ensured to be firm and unchanged, which further affects the processing, production and assembly. Many processes require manual operation and human testing, which cannot promote mass production.
进一步地,在本发明所实施的技术方案中,于盖体一2表面中心位置处增设电极引出孔4来引出电极组件5,在生产装配时,焊接、安装更加方便,只要采用相应的设备使得电芯密封于壳体1与盖体一2之间的内腔之后,便无需再次打开盖体或壳体1,可通过预留的电极引出孔4来装配电极组件5,因而,该技术手段带来的后处理方式,优于以往如图7所列举的传统的将壳体1、盖体一2、以及电极组件5逐一按照复杂顺序固定装配的方式。Further, in the technical solution implemented in the present invention, an electrode lead-out hole 4 is added at the center position of the surface of the cover 1-2 to lead out the electrode assembly 5. During production and assembly, welding and installation are more convenient, as long as the corresponding equipment is used to make After the electric core is sealed in the inner cavity between the housing 1 and the cover 1-2, there is no need to open the cover or the housing 1 again, and the electrode assembly 5 can be assembled through the reserved electrode lead-out hole 4. Therefore, this technical means The resulting post-processing method is better than the conventional method of fixing and assembling the housing 1, the cover-2, and the electrode assembly 5 one by one in a complicated order as illustrated in FIG. 7.
进一步地,在本发明所实施的技术方案中,于盖体一2表面适当位置处增设注液孔3用于注液处理,在生产装配时,只要采用相应的设备使得电芯密封于壳体1与盖体一2之间的内腔之后,便无需再次打开盖体或壳体1,可通过预留的注液孔3来注液,因而,该技术手段带来的后处理方式,优于以往传统方式。Further, in the technical solution implemented in the present invention, a liquid injection hole 3 is added at an appropriate position on the surface of the cover 2 for liquid injection treatment. During production and assembly, only the corresponding equipment is used to seal the battery core in the housing. After the inner cavity between 1 and cover 1-2, there is no need to open the cover or housing 1 again, and the liquid can be injected through the reserved liquid injection hole 3. Therefore, the post-processing method brought by this technical means is excellent In the traditional way in the past.
实施例二Example two
如图3、图4所示,对于拟实施的利于促进量产化的穿戴电池结构,在实施例一所实施的壳体1的基础上,所实施的穿戴电池结构还包括用于与壳体1 组合装配以便于将电芯密封在内部的盖体二6,虽然与实施例一所采用的盖体一2圆盘形状相同,但是盘面的面积大于壳体1横截面的面积,以便于使盖体二6完全遮盖于壳体1,而不仅仅如盖体一2只覆盖在壳体1的外边缘。As shown in Figures 3 and 4, for the proposed wearable battery structure that facilitates mass production, on the basis of the housing 1 implemented in the first embodiment, the implemented wearable battery structure further includes 1 Assemble the cover body 2 6 that is used to seal the battery core inside. Although the shape of the cover body 2 is the same as that of the cover body 2 used in the first embodiment, the area of the disk surface is larger than the cross-sectional area of the shell 1 so as to make it easier to make The cover 2 6 completely covers the casing 1, not just covering the outer edge of the casing 1 like the cover 1 2.
同时,对于盖体一2表面中心位置处增设电极引出孔4来引出电极组件5,以及注液孔3的设置,可参照实施例一,此处不再赘述。At the same time, for the additional electrode lead-out hole 4 at the center of the surface of the cover 2 to lead out the electrode assembly 5, and the arrangement of the liquid injection hole 3, please refer to the first embodiment, which will not be repeated here.
实施例三Example three
如图5、图6所示,对于拟实施的利于促进量产化的穿戴电池结构,在实施例一、实例二所实施的壳体1的基础上,所实施的穿戴电池结构还包括用于与壳体1组合装配以便于将电芯密封在内部的盖体三7,与实施例一、实例二所采用的盖体结构不同,本实施例三所实施的盖体三7内表面(即面向壳体1内部的一面)设置防爆槽8,优先采用激光雕刻方式设置该防爆槽8,并且所采用的激光雕刻设备均为本领域技术人员惯用的、易于操作的,且本领域技术人员采用这一类激光雕刻设备能够轻易地于盖体内部实施防爆槽8,所实施的防爆槽8优选采用一条弧形结构。As shown in Figures 5 and 6, for the proposed wearable battery structure that facilitates mass production, on the basis of the housing 1 implemented in the first and second embodiments, the implemented wearable battery structure also includes The cover body three 7 assembled with the housing 1 to facilitate the sealing of the battery core inside is different from the cover body structure adopted in the first and second embodiments. The inner surface of the cover body three 7 implemented in the third embodiment (ie The side facing the inside of the housing 1) is provided with an explosion-proof groove 8. The explosion-proof groove 8 is preferably provided by laser engraving, and the laser engraving equipment used is commonly used by those skilled in the art and easy to operate, and those skilled in the art use This type of laser engraving equipment can easily implement an explosion-proof groove 8 inside the cover, and the implemented explosion-proof groove 8 preferably adopts an arc structure.
经过实际测试可知,通过设置防爆槽8,有利于缓冲穿戴电池爆炸产生的爆破力,即便防爆槽8位置处受到爆破冲击而破裂,也仅是撕开一道较小的裂缝,不会因产生大面积的损坏而使穿戴电池沿着破损处掉出,这相比以往采用防爆通孔的方式要明显更为优越;因此,在具备防爆功能的基础上,使得穿戴电池更加便于量产化。Through actual tests, it can be seen that by setting the explosion-proof groove 8, it is beneficial to buffer the blasting force generated by the explosion of the wearable battery. The damage to the area causes the wearable battery to fall out along the damage, which is significantly better than the previous explosion-proof through-hole method; therefore, on the basis of the explosion-proof function, the wearable battery is more convenient for mass production.
