Abstract

本实用新型公开了摩托车车用活性炭罐，包括有炭罐盖和炭罐本体，炭罐本体上具有与炭罐盖扣合的凹槽，所述的炭罐盖内部均布有多个倒扣凸沿，倒扣凸沿和炭罐本体的凹槽紧密衔接，紧固效果完全能确保成品拔脱力≥30kgf，保证100%的量品力；降低了炭罐盖1与炭罐本体2压合工序的不良率：30%→0%，同时提升了生产效率。

Description

摩托车车用活性炭罐
技术领域
本实用新型涉及产品是摩托车车用活性炭罐；是指具有改良结构的活性炭罐。
背景技术
目前，该炭罐属组合型，罐体上面的PCV（负压控制阀）小盖与炭罐本体的接合采用直接压扣的方式，传统的设计是在上盖设计一整圈的凸沿和本体的凹槽扣合，存在的弊端主要是批量生产后不良率高（不良率：30%），在拔脱力没达到30kgf时会导致小盖和炭罐本体脱离，不能达到足够的紧固度。主要不良项目是：压合过程中盖子易破裂、把脱力满足不了性能要求。另外，原始设计的模具加工也较为复杂。
实用新型内容
本实用新型的目的在于提供一种对炭罐盖进行结构改良的活性炭罐，可以在简化模具加工的同时确保生产过程100%的良品率。
上述目的，通过如下技术方案实现：
摩托车车用活性炭罐，包括有炭罐盖和炭罐本体，炭罐本体上具有与炭罐盖扣合的凹槽，其特征在于：所述的炭罐盖内部均布有多个倒扣凸沿，倒扣凸沿和炭罐本体的凹槽紧密衔接。
所述的倒扣凸沿上部为镂空部位。
所述的倒扣凸沿在炭罐本体内圈均布有六个。
采用上述多点倒扣装配结构，炭罐内圈设置的六个倒扣凸沿端面与炭罐本体装配凹槽扣合是面与面的紧密衔接，紧固效果完全能确保成品拔脱力≥30kgf，保证100%的良品率；降低了炭罐盖与炭罐本体压合工序的不良率：30%→0%，同时提升了生产效率。凸沿上部采用的镂空结构，可以降低模具加工的复杂性。
附图说明
图1为本实用新型的结构示意图；
图2为本实用新型炭罐盖的结构示意图；
图3为图2的A-A剖面图；
图4为本实用新型炭罐盖的仰视图。
具体实施方式
下面结合附图对本实用新型作进一步说明。
如图1、2、3、4所示，摩托车车用活性炭罐，包括有炭罐盖1和炭罐本体2，炭罐本体2上具有与炭罐盖1扣合的凹槽，所述的炭罐盖1内部均布有多个倒扣凸沿3，倒扣凸沿3在炭罐本体2内圈均布有六个数目，倒扣凸沿3和炭罐本体2的凹槽紧密衔接，其中所述的倒扣凸沿3上部为镂空部位4，可以降低模具加工的复杂性。
采用上述多点倒扣装配结构，炭罐盖1内圈设置的六个倒扣凸沿3端面与炭罐本体2装配凹槽扣合是面与面的紧密衔接，紧固效果完全能确保成品拔脱力≥30kgf，保证100%的量品力；降低了炭罐盖1与炭罐本体2压合工序的不良率：30%→0%，同时提升了生产效率。
