Description

一种换电连接器 技术领域
本申请涉及电池技术领域，特别是涉及一种换电连接器。
背景技术
在换电时，随着新的动力电池被安装到汽车上，换电连接器实现了动力电池与汽车的电连接。具体地，换电连接器在电池包端的插头插合到在电动汽车的车身端的插座，插头端子和插座端子插合实现电连接。
现有技术的换电连接器，需要将电池包端的插头严格对准车身端的插座，才能顺利实现插合。为便于快速实现插合，常常需要导向结构将插头导向至插座，但现有换电连接器的导向结构和对插结构为分开独立，导致导向结构和对插结构整体占用较大的体积和重量。
发明内容
本申请的目的在于提供一种换电连接器，以通过将导向结构与对插结构集成在一起，缩小换电连接器本体的尺寸并减轻重量，提高电动车在换电过程的对中插合效率。

在一些实施方式中，所述导向固定块竖直设置且所述导向动块相对于所述导向固定块倾斜设置，或所述导向动块竖直设置且所述导向固定块相对于所述导向动块倾斜设置。
在一些实施方式中，所述公端还包括公端密封圈以及公端外壳，所述公端密封圈套置在所述公端外壳上，所述母端还包括母端外壳，在所述导向动块与所述导向固定块成角度接触，以将所述母端导向至与所述公端对中的过程中，所述母端外壳的至少一部分与所述 公端密封圈不接触。
在一些实施方式中，所述导向固定块设置于所述公端外壳的顶部。
在一些实施方式中，所述导向动块与所述母端外壳的内表面贴合。
在一些实施方式中，在所述母端与所述公端对中并连接后，所述导向动块的顶部以及底部分别与所述公端外壳的外表面抵接。
在一些实施方式中，在所述母端与所述公端对中并连接后，所述母端外壳的内表面分别与所述公端外壳的外表面以及所述导向固定块的外表面抵接。
在一些实施方式中，在所述母端与所述公端对中并连接后，所述母端外壳的底部与所述公端密封圈抵接，且所述母端外壳的内表面还与所述公端密封圈抵接。
在一些实施方式中，所述公端还包括公端端子以及公端低压端子，所述母端还包括母端端子以及母端低压端子，所述公端端子以及所述公端低压端子能够分别与所述母端端子以及所述母端低压端子插接配合。
本申请的有益效果至少包括：
1、本申请通过将导向动块以及导向固定块分别组合到母端和公端本体上，缩小了换电连接器本体的尺寸并减轻重量，可以有效提高电动车在换电过程的对中插合效率。
2、本申请通过采用倾斜设置的导向动块的倾斜内表面与竖直设置的导向固定块的顶部成角度接触配合以导向母端与公端对中，能够根据需要调节导向固定块与导向动块的配合尺寸，从而设计不同的浮动导向尺寸。
3、本申请通过使得在导向动块与导向固定块成角度接触，以将母端导向至与公端对中的过程中，母端外壳不与公端密封圈接触，可以有效防止在导向母端与公端对中过程中，母端与公端密封圈的提前接触，从而防止公端密封圈的破损。

第一竖直部133竖直设置，斜面部132以及导向动块12相对于第一竖直部133均倾斜(所成角度不包括90度)设置，导向动块12与斜面部132平行且贴合于斜面部132的内表面，导向动块12的顶部与凸起部131的底部接触，导向动块12的底部与第一竖直部133的顶部接触。导向动块12能够与导向固定块22配合以导向母端10与公端20的插接配合，在母端10与公端20插接配合后，第一竖直部133的底部以及内表面能够与公端密封圈25抵接。
公端20包括公端端子21、导向固定块22、公端外壳23、公端低压端子24以及公端密封圈25，其中，公端端子21以及公端低压端子24均设置于公端外壳23的内部，导向固定块22竖直设置于公端外壳23的顶部，公端密封圈25套置在公端外壳23上。公端端子21以及公端低压端子24均呈柱状，且公端端子21以及公端低压端子24的数量分别与母端端子11以及母端低压端子14对应。公端端子21的直径大于公端低压端子24的直径，公端端子21设置于公端低压端子24的两侧，母端端子11以及母端低压端子14分别能够与公端端子21以及公端低压端子24插接配合。
公端外壳23包括第二竖直部231、第一水平部232、第三竖直部233以及第二水平部234，第二竖直部231竖直设置且其底部与第一水平部232的第一端部连接，第一水平部232水平设置且第三竖直部233的顶部与第一水平部232的第二端部连接，第三竖直部233竖直设置且其底部与第二水平部234连接，导向固定块22设置于第二竖直部231的顶部，且导向固定块22的外表面与第二竖直部231的外表面齐平。在母端10与公端20未对中且母端10向公端20插合的过程中，倾斜设置的导向动块12的倾斜内表面能够与竖直设置的导向固定块22的顶部成角度(不包括90度)接触，导向动块12的倾斜内表面受到导向固定块22挤压，以使得母端10倾斜移动，当母端10被导向移动至第一竖直部133 的底部与第一水平部232齐平时，导向动块12的顶部与导向固定块22的顶部即将分离，母端端子11与公端端子21能够插接配合，且母端低压端子14与公端低压端子24能够插接配合，从而快速实现母端10与公端20的对中和插接，如图4所示。
本申请通过将导向动块12以及导向固定块22分别组合到母端10和公端20本体上，缩小了换电连接器本体的尺寸并减轻重量，可以有效的提高电动车在换电过程的对中插合效率。此外，本申请通过采用倾斜设置的导向动块12的倾斜内表面与竖直设置的导向固定块22的顶部成角度接触配合以导向母端10与公端20对中，能够根据需要调节导向固定块22与导向动块12的配合尺寸，从而设计不同的浮动导向尺寸L，如图5所示。
如图6所示，在母端端子11以及母端低压端子14分别与公端端子21以及公端低压端子24插接配合后，导向动块12的顶部以及底部分别与第二竖直部231以及第一水平部232的外表面抵接，凸起部131的内表面与第二竖直部231的外表面以及导向固定块22的外表面抵接，公端密封圈25与第三竖直部233以及第二水平部234接触，第一竖直部133的底部与公端密封圈25抵接，第一竖直部133的内表面与公端密封圈25以及第三竖直部233抵接。
本申请通过使得在导向动块12与导向固定块22成角度接触，以将母端10导向至与公端20对中的过程中，母端外壳13不与公端密封圈25接触，可以有效防止在导向母端10与公端20对中过程中，母端10与公端密封圈25的提前接触，从而防止公端密封圈25的破损。
提供所公开的方面的以上描述以使本领域的任何技术人员能够实施本申请。对这些方面的各种修改对于本领域技术人员而言是显而易见的，并且在此定义的一般原理可以应用于其他方面而不脱离本申请的范围。因此，本申请不意图被限制到在此示出的方面，而是按照与在此公开的原理和新颖的特征一致的最宽范围。
