具体实施方式
下面结合附图具体实施例对本发明作进一步说明。
本发明第一实施例以1×6为例进行详细说明，如图1-6所示，本发明所述的方向以图1所示为准，图1铅酸蓄电池水平放置，铅酸蓄电池的上方、下方即为电池盖3的上方、下方。本发明所述电池由水平放置使用的电池槽1、极板水平放置使用的极群组2、电池盖3、胶帽4、小盖片5和大盖片6等组成，电池盖3上预设有第一端子302、第二端子303；通过第一端子302和第二端子303对外形成电连接。电池槽1为方体结构，由六个单体格11沿上下方向依次排列，单体格11的厚度方向呈上下水平放置，与水平放置使用状态的单极群21中的极板相对应，此种放置状态能够有效地抑制硫酸电解液分层现象，从而减轻极板因硫酸盐化而失效的风险；沿6个单体格11的侧沿，设有整圈的凸起封胶沿12，用于与电池盖3的封胶沟314配合并用密封胶密封；在电池槽1的上下两个端面外侧分别设有数条加强筋13，防止极板在充放电过程中因膨胀而导致电池槽1上下端面发生变形而影响电池的使用寿命；此电池槽1的上下两个端面外侧的加强筋13为单方向脱模结构设计，利于降低电池槽1的制造成本和提高生产效率；
如图3所示，极群组2由六个单极群21和一系列汇流排24组成；其中单极群21由正极板、AGM隔板、负极板及边负极板按照工艺要求排列组成；其极板呈水平放置，与电池槽1的单体格11相对应，其极性按工艺要求正、负交替排列；其极耳与相应的一系列汇流排24按工艺要求通过铸焊实现电连接，且第一个单极群，即电池水平放置时，最上方的那个单极群21上的汇流排上设有第一极柱22，第六个单极群，即电池水平放置时，最下方的那个单极群21上的汇流排上设有第二极柱23；电池水平放置时，也就是极群组2在水平使用状态下，第一极柱22靠近电池盖3的上表面3a、第二极柱23远离电池盖3的上表面3a；为了顾客使用方便和使用安全，需要将第二极柱23引到电池盖3的上表面3a，利于用户外连接用电使用。
如图4-6所示，电池盖3为一长方体结构，按使用状态沿上下方向设六个单 体格301，电池盖3的单体格301与电池槽的单体格11相对应，在每个单体格301的中间位置各设一个胶帽座304，胶帽座304与胶帽4配合，控制电池在使用状态下的开闭阀压力；在每个胶帽座304的中间各设一个注液孔313，注液孔313为贯穿电池盖3的通孔，用于化成注入/抽出酸液之用，也是排出电池内部压力气体的通道；在每两个胶帽座304之间，设有排气沟310，其作用是使从注液孔313排出气体能够顺利地排到电池的外面；沿排气沟310中心线在两侧对称设有两条汇流排背沟306，其位置和尺寸与极群组2上的汇流排24相对应；在第一个单体格和第六个单体格的胶帽座304的同侧，电池盖3上各设一个极柱帽309a、309b，极柱帽309a、309b最好为正六棱柱形；在第一个单体格的胶帽座304的两侧，电池盖3上分别设有第一端子302和第二端子303，如图7-11，第一端子302包括外接线端302a和第一电连接片323，第一端子302预设在电池盖3上，其第一电连接片323的位置与极柱帽309a对应，第二端子303包括外接线端303a、导线311和第二电连接片331,第二端子303预设在电池盖3上，其第二电连接片331的位置与极柱帽309b对应，在电池水平放置时，也就是极板板面水平放置时，第一端子302的外接线端302a和第二端子303的外接线端303a从电池盖3的上侧面3a露出，这里的露出是指在电池水平放置时，用户可以从电池上方进行对外电连接；电池盖的上侧面3a包括最低面和最高面，第一端子302的外接线端302a和第二端子303的外接线端303a最好伸出电池盖的上侧面的最低面而低于电池盖的上侧面的最高面。在电池盖3的表面还设有8个固定孔307，用于固定大盖片6；在电池盖3表面左、下、右三面边缘还设有凸起的裙边308，与大盖片配合起到装饰和保护作用；在电池盖3的背面设两条汇流排沟315，汇流排沟315的位置与汇流排背沟306及极群组2的汇流排24相对应，其尺寸要稍大于极群组2的汇流排24的尺寸，利于用密封胶将汇流排24封装于汇流排沟315内，起到密封作用；在电池盖3的背面与两个极柱帽309a、309b对应位置各设一个极柱孔312a、312b，极柱孔用于电池在封盖时将极柱插入；在生产过程中进行到焊端子工序时，需要将第一极柱22和第二极柱23上方的极柱帽309a、309b用专用扳手去掉，露出第一电连接片323和第二电连接片331的铜质表面，分别与极群组2的第一极柱22和第一极柱23焊接；在电池盖3的背面与槽1上的胶封沿12对应位置设有相应的封胶沟314，在装配时将封胶沿12插入封胶沟314中，通过密封胶进行密封；
第一端子302包括外接线端302a和第一电连接片323，外接线端包括外接线端面为一较薄的四方形状的第一方台317，在第一方台317的下表面中心设一个第一圆台318，在第一圆台318下表面再设一个较薄的四方形状的第二方台319，在第二方台319的下表面中心设一个第二圆台二320，在第一方台317的上表面中心向下设一个螺孔321，用于连接外部连接线时紧固之用；在第二圆台320的下表面合适位置垂直于下表面设一个方形片状的第一方片322，在第一方片322的下端设一个同厚度的圆环形状的环片，第一电连接片323可以包括环片和第一方片322，第一电连接片323的环片的内环直径与极群组2上的第一极柱22的直径相对应；各圆台、方台的最小直径要大于螺孔321的直径，各圆台、方台厚度之和要大于螺孔321的深度；整个第一端子302可以全部预设在电池盖3中，第一端子302只要露出电池盖3即可，也就是可以对外形成电连接，最好第一方台317的上表面伸出电池盖3的最低面且低于电池盖3的最高处即最上方的表面，这样一方面方便对外电连接，另一方面可以防止电池上端面被错误地相对放在一起时造成短路打火的危险；第二端子303包括外接线端303a和第二电连接片331，其外接线端面为铜质材料，包括一较薄的四方形状的第三方台324，在第三方台324的下表 面中心设一个第三圆台325，在第三圆台325下表面再设一个较薄的四方形状的第四方台326，在第四方台326的下表面中心设一个第四圆台327，在第四圆台327的下表面合适位置垂直于下表面设一个缺口328，用于放置并焊接导线311的一端，实现导线311与外接线端的电连接；导线311的另一端与第二电连接片331电连接；在第三方台324的上表面中心向下设一个螺孔329，用于连接外部连接线时紧固之用；各圆台、方台的最小直径要大于螺孔329的直径，各圆台、方台厚度之和要大于螺孔329的深度；整个第二端子303可以全部预埋在电池盖3中，第二端子303只要露出电池盖3即可，也就是可以对外形成电连接，此外最好第二端子303的外接线端303a伸出电池盖3的最低面，且低于电池盖3的最高处即最上方的表面，这样一方面方便对外电连接，另一方面可以防止电池上端面被错误地相对放在一起时造成短路打火的危险；螺孔321与螺孔329的规格一致，保证使用的通用性；第二电连接片331最好为为铜质材料，由一个矩形片状的方片330和在方片330下端设一个同厚度的圆环332两部分组成，圆环332的内环直径与极群组2上的第二极柱23的直径相对应；方片330与导线311的剩余一端通过焊接实现电连接；第二电连接片331及导线311全部预设在电池盖3中，导线311可以从任何一条预设线路333敷设并预设在预埋管305之中，导线、预埋管305和端子同时预先注塑在电池盖中；省去了后期生产过程中的安装步骤，提高了生产效率，防止了酸液腐蚀，提高了安全性。
本实施例第一端子302和第二端子303的预设在电池盖3的生产过程中进行，事先要将包括导线311及第二电连接片331的第二端子303按要求进行电连接在一起，然后在电池盖3生产时将第一端子302及第二端子303组成的组合体分别安装在注塑模具的相应位置，继续合模注塑生产，实现第一端子302、第二端子303与电池盖3的注塑一体成型，完成预设操作。此处的一体成型的含义也就是电池盖在安装到电池槽上的同时，可以实现第一端子和第二端子也随同电池盖一同安装到电池槽上，此处的一体成型也可以理解为实现第一端子302以及第二端子303预设在电池盖3上。本发明的第一端子302包括外接线端和第一电连接片323，在与电池盖3完成注塑一体成型后，最好第一端子302的外接线端302a与第一端子的第一电连接片323通过电池盖3实现密封隔离，此处密封隔离的含义是实现密封胶无法通过电连接片爬升并从端子处外溢，也就是密封胶无法通过第一电连接片323爬升并从第一端子302的外接线端302a处外溢，此时第一端子302的外接线端302a或第一端子的第一电连接片323中的至少一个的外表面与电池盖3以注塑密封的方式密封隔离，如第一圆台318的外表面与电池盖3注塑密封或第一方片322的外表面与电池盖3注塑密封，第二端子303原理同样。
本发明的第一端子302及第二端子303与电池盖的一体成型除了注塑之外，也可以通过其他合适的方式，如焊接安装等其他方式，可以实现一体成型即可，此处的一体成型的含义也就是电池盖在安装到电池槽上的同时，可以实现第一端子和第二端子也随同电池盖一同安装到电池槽上，此处的一体成型也可以理解为实现第一端子302以及第二端子303预设在电池盖3上。焊接方式的一体成型，第一端子302及第二端子303与电池盖3进行焊接，最好实现端子的外接线端与端子的电连接片通过电池盖3密封隔离，此处密封隔离的含义是实现密封胶无法通过电连接片爬升并从端子处外溢，也就是密封胶无法通过第一电连接片323爬升并从第一端子302的外接线端302a处外溢，此时第一端子302的外接线端302a或第一端子的第一电连接片323中的至少一个的周围完全与电池盖3以焊接密封的方式密封隔离，如第一圆台318的外表面与电池盖3焊接密封或第一方片322 的外表面与电池盖3焊接密封，第二端子303原理同样。生产时，事先要将包括导线311及第二电连接片331的第二端子303按要求进行焊接在一起，然后在电池盖3生产时将第一端子302及第二端子303组成的组合体分别焊接在电池盖3上，实现第一端子302、第二端子303与电池盖3的一体成型，完成预设操作。
第一端子302和第二端子303的各方台、圆台交替相连的结构，利于在预设时增加抗扭力，防止在紧固端子时产生松动或脱落；
胶帽4为六个，与胶帽座304的数量相一致，使用状态下与电池盖3上的胶帽座304相配合，起到控制开闭阀压力的作用；
小盖片5使用状态下与电池盖3通过胶封或超声波焊接而装配在一起，并压住胶帽4(限制其开阀时的位置)，以达到精确控制开阀压力的作用，保证电池组失水的一致性，延长电池组的整体寿命；
大盖片6使用状态下通过胶封、或超声波焊接、或卡扣连接方式与电池盖3相配合，并镶嵌于电池盖3中，起到装饰、品牌宣传和端子保护作用；
本实施例1的铅酸蓄电池的制造方法如下：步骤一，将包括第一极柱22和第二极柱23的极群放入电池槽；步骤二，电池槽封上电池盖，电连接第一端子302与第一极柱22；电连接第二端子303与第二极柱23，端子进行封胶；步骤三，化成；步骤二之前还包括将第一端子302以及第二端子303预设在电池盖3中的步骤。步骤一可以是先将包括第一极柱22和第二极柱23的极群进行铸焊，之后放入电池槽1；还可以先将极群入槽至适当位置，再进行铸焊形成汇流排，最后将极群组压至到槽底。如图14，步骤二中，端子与极柱的电连接方式，如焊接方式可以通过预先设置极柱帽，之后去除极柱帽进行焊接的方式之外，也可以不预先设置极柱帽，此时可以将第一端子所在的汇流排所对应的汇流排沟315去掉，仅需设置安装O形圈316的凹槽及在极柱上增加安装O形圈316的台阶，最后用端子胶来完成极柱密封，这样可以省掉去极柱帽的过程，但同时也增加了上O形圈的过程，该方式端子与极柱的焊接方式，也就是本发明实施例3的为普通电池的端子与极柱的焊接方式，第二电连接片332及第二极柱23作相同处理；本实施例1的制造方法将第一端子302以及第二端子303预设在电池盖3中一体成型的方式可以是注塑也可以是焊接等方式，最好第一端子302的外接线端302a或第一端子的第一电连接片323中的至少一个的周围与电池盖3以注塑密封或焊接密封的方式密封隔离，如第一圆台318的外表面与电池盖3注塑密封或焊接密封或第一方片322的外表面与电池盖3注塑密封或焊接密封，第二端子303原理同样。本发明的制造过程，最大程度地保证了利用现有设备，不增加过多时间成本和人工成本来完成电池的制造。本发明的电连接片可以是环片形式，也可以根据需要是其他合适的形式如导线形式。
图12是本发明的实施例2，水平电池极群以2×3形式排列的电池示意图，图中1M、3M、21M、24M、22M、23M、302M、303M与实施例1相应标识的构件一致，极群组在水平使用状态下，第一极柱22M和第二极柱23M均靠近电池盖3M的上表面；与第一实施例相比，由于第二极柱23M靠近电池盖3M的上表面，因此第二端子303M不需要使用导线长距离与第二极柱23M实现电连接，第二端子303M与第二极柱23M的电连接方式与第一端子302M与第一极柱22M的电连接方式近似一样，制造方法如下，步骤一，将包括第一极柱22M和第二极柱23M的极群放入电池槽；步骤二，电池槽1M封上电池盖3M，电连接第一端子302M与第一极柱22M；电连接第二端子303M与第二极柱23M，端子进行封胶；步骤三，化成；步骤二之前还包括将第一端子302M以及第二端子303M预设在电池盖3M中的步骤。步骤一 可以是先将包括第一极柱22M和第二极柱23M的极群进行铸焊，之后放入电池槽；还可以先将极群入槽至适当位置，再进行铸焊形成汇流排，最后将极群组压至到槽底。如图14，步骤二中，端子与极柱的电连接方式，如焊接方式可以通过预先设置极柱帽，之后去除极柱帽进行焊接的方式之外，也可以不预先设置极柱帽，此时也可以将第一端子所在的汇流排所对应的汇流排沟315去掉，仅需设置安装O形圈316的凹槽及在极柱上增加安装O形圈316的台阶，最后用端子胶来完成极柱密封，这样可以省掉去极柱帽的过程，但同时也增加了上O形圈的过程，该方式端子与极柱的焊接方式，也就是本发明实施例3的为普通电池的端子与极柱的焊接方式，第二电连接片332及第二极柱作相同处理；本实施例1的制造方法将第一端子302M以及第二端子303M预设在电池盖3中一体成型的方式可以是注塑也可以是焊接等方式，最好第一端子302M的外接线端或第一端子302M的第一电连接片中的至少一个的周围完全与电池盖3以注塑密封或焊接密封的方式密封隔离，第二端子303M原理同样。
图13是本发明的实施例3，普通电池极群以2×3形式排列的电池示意图，即电池使用时极群非水平状态而是立式状态，另外汇流排为直连跨桥连接。图中1N、3N、21N、24N、22N、23N、302N、303N与实施例1相应标识的构件一致，本发明实施例1的方法也可应用与普通电池，即第一端子和第二端子预设在电池盖3N中。制造方法如下，步骤一，将包括第一极柱22N和第二极柱23N的极群放入电池槽；步骤二，电池槽1N封上电池盖3N，电连接第一端子302N与第一极柱22N；电连接第二端子303N与第二极柱23N，端子进行封胶；步骤三，化成；步骤二之前还包括将第一端子302N以及第二端子303N预设在电池盖3N中的步骤。步骤一，将包括第一极柱22N和第二极柱23N的极群放入电池槽1N；步骤二，电池槽1N封上电池盖N，电连接第一端子302N与第一极柱22N；电连接第二端子303N与第二极柱23N，端子进行封胶；步骤三，化成；步骤二之前还包括将第一端子302N以及第二端子303N预设在电池盖3N中的步骤。步骤一可以是先将包括第一极柱22N和第二极柱23N的极群进行铸焊，之后放入电池槽；还可以先将极群入槽至适当位置，再进行铸焊形成汇流排，最后将极群组压至到槽底。如图14，步骤二中，端子与极柱的电连接方式，如焊接方式可以通过预先设置极柱帽，之后去除极柱帽进行焊接的方式之外，也可以不预先设置极柱帽，此时也可以将第一端子所在的汇流排所对应的汇流排沟315去掉，仅需设置安装O形圈316的凹槽及在极柱上增加安装O形圈316的台阶，最后用端子胶来完成极柱密封，这样可以省掉去极柱帽的过程，但同时也增加了上O形圈的过程，该方式端子与极柱的焊接方式，也就是本发明实施例3的为普通电池的端子与极柱的焊接方式，第二电连接片332及第二极柱作相同处理。本实施例1的制造方法将第一端子302N以及第二端子303N预设在电池盖3中一体成型的方式可以是注塑也可以是焊接等方式，最好第一端子302N的外接线端或第一端子302N的第一电连接片中的至少一个的周围完全与电池盖3以注塑密封或焊接密封的方式密封隔离，第二端子303M原理同样。
本发明还保护了一种用于本发明铅酸蓄电池的电池盖、一种使用本发明铅酸蓄电池的电动车。
