技术领域
本申请涉及电池技术领域，具体涉及一种电池箱。
背景技术
目前，在搬运或使用电芯时，为了避免电芯与其他物体发生碰撞致使电芯损坏，常将电芯放置在电池箱中。如此，即使在发生碰撞时，也是位于电芯外部的电池箱与其他物体发生碰撞，从而减小电芯的受力，以避免电芯损坏。
然而，相关技术的电池箱在容置电芯后，由于电芯重量较重，易使电池箱的箱体在重力方向上产生变形，从而降低电池箱的使用寿命。
发明内容
鉴于上述问题，本申请提供一种电池箱，在电池箱容置电芯后，可避免电池箱的箱体在重力方向上产生变形，从而提升电池箱的使用寿命。
本申请提供了一种电池箱，包括：箱体，用于容置电芯，箱体具有顶板以及与顶板相对设置的底板，底板用于从电芯的下方支撑电芯；至少一抱箍，抱箍环绕箱体，抱箍包括上部以及与上部相对设置的下部，上部位于顶板远离底板的一侧、并与顶板抵接，下部位于底板远离顶板的一侧、并与底板抵接。
本申请实施例的技术方案中，箱体，用于容置电芯，箱体具有顶板以及与顶板相对设置的底板，底板用于从电芯的下方支撑电芯；至少一抱箍，抱箍环绕箱体，抱箍包括上部以及与上部相对设置的下部，上部位于顶板远离底板的一侧、并与顶板抵接，下部位于底板远离顶板的一侧、并与底板抵接。这样的设计，可通过抱箍环绕箱体且抱箍的上部位于顶板远离底板的一侧、并与顶板抵接，以及抱箍的下部位于底板远离顶板的一侧、并与底板抵接，以将抱箍设置在箱体上，并在箱体容置电芯且箱体的底板从电芯的下方支撑电芯后，可通过抱箍的下部从箱体的下方支撑箱体，进而避免箱体在重力方向上产生变形，以提升电池箱的使用寿命。
在一些实施例中，抱箍还包括第一连接部以及第二连接部，上部包括第一分体以及第二分体，第一分体的一端经由第一连接部与下部相连，第二分体的一端经由第二连接部与下部相连，第一分体远离第一连接部的一端与第二分体远离第二连接部的一端抵接并固定。由于第一分体的一端经由第一连接部与下部相连、且第二分体的一端经由第二连接部与下部相连，因此，将第一分体远离第一连接部的一端与第二分体远离第二连接部的一端抵接并固定后，即可将抱箍稳定地固定在箱体上。
在一些实施例中，上部还包括自第一分体远离第一连接部的一端沿远离箱体的方向弯折延伸的第一固定部、以及自第二分体远离第二连接部的一端沿远离箱体的方向弯折延伸的第二固定部，第一固定部与第二固定部抵接并固定。通过设置第一固定部以及第二固定部、且第一固定部与第二固定部抵接并固定，可增加第一分体与第二分体固定时的稳定性。
在一些实施例中，电池箱还包括：贯穿第一固定部以及第二固定部、并将第一固定部与第二固定部固定的第一紧固件。如此，可进一步增加第一固定部与第二固定部固定时的稳定性，从而进一步增加第一分体与第二分体固定时的稳定性。
在一些实施例中，抱箍一体成型。如此，可降低电池箱在组装时的组装成本。
在一些实施例中，箱体包括上盖以及下箱体，上盖具有顶板，上盖固定于下箱体，下箱体具有底板。如此，在将电芯置于箱体内时，可先将上盖与下箱体分离，并将电芯置于上盖与下箱体之间后，再将上盖固定于下箱体，以使箱体容置电芯。
在一些实施例中，抱箍还包括第三连接部、第四连接部、第五连接部以及第六连接部，第三连接部与第五连接部固定，第四连接部与第六连接部固定；第三连接部与第四连接部相对设置在上部的两端，第三连接部、上部以及第四连接部依次相连；第五连接部与第六连接部相对设置在下部的两端，第五连接部、下部以及第六连接部依次相连。由于第三连接部、上部以及第四连接部依次相连，第五连接部、下部以及第六连接部依次相连，因此，在将第三连接部与第五连接部固定且第四连接部与第六连接部固定后，即可确保抱箍的上部以及下部稳定地固定在箱体上。
在一些实施例中，抱箍还包括自第三连接部远离上部的一端沿远离第四连接部的方向弯折延伸的第一延伸部、以及自第五连接部远离下部的一端沿远离第六连接部的方向弯折延伸的第二延伸部；第一延伸部与第二延伸部固定。由于第一延伸部与第三连接部相连，第二延伸部与第五连接部相连，因此，通过第一延伸部与第二延伸部固定，可增加第三连接部与第五连接部固定时的稳定性。
在一些实施例中，箱体包括上盖以及下箱体，上盖具有顶板以及与顶板固定的第一法兰，下箱体具有底板以及与底板固定的第二法兰，第一法兰与第二法兰固定；第一延伸部位于第一法兰远离第二法兰的一侧，第二延伸部位于第二法兰远离第一法兰的一侧；第一延伸部以及第二延伸部固定，并夹持第一法兰以及第二法兰。由于第一延伸部与第二延伸部夹持第一法兰以及第二法兰，且第一延伸部与第二延伸部固定，因此，可增加第一法兰与第二法兰固定时的稳定性以及第一法兰与第二法兰之间的密封性。
在一些实施例中，电池箱还包括：第二紧固件；第二紧固件依次贯穿第一延伸部、第一法兰、第二法兰以及第二延伸部，并将第一延伸部与第二延伸部固定。如此，可进一步增加第一法兰与第二法兰固定时的稳定性以及第一法兰与第二法兰之间的密封性。
在一些实施例中，第一延伸部和/或第二延伸部设有用于与挂载件固定的安装块。如此，当需将电池箱与挂载件固定时，可通过抱箍的安装块与挂载件固定，从而在电池箱与挂载件固定时，增加抱箍的下部对箱体的支撑力。
在一些实施例中，箱体表面具有凹槽，抱箍的至少部分卡设与凹槽内。如此，在将抱箍设置在箱体上后，可避免抱箍与箱体之间发生相对移动。
在一些实施例中，凹槽包括设置在顶板的第一凹槽、以及设置在底板的第二凹槽，第一凹槽以及第二凹槽沿相互靠近的方向凹陷；上部的至少部分卡设于第一凹槽内；下部的至少部分卡设于第二凹槽内。
在一些实施例中，箱体还具有两相对设置且均与顶板以及底板相连的侧板；凹槽包括分别位于一侧板、且沿相互靠近的方向凹陷的两个第三凹槽；抱箍卡设于两个第三凹槽内。
在一些实施例中，电池箱还包括：缓冲垫；箱体的形状为长方体或类长方体；缓冲垫位于箱体与抱箍之间、并处于箱体的转角处。如此，可避免抱箍与箱体转角处发生摩擦，以提升抱箍以及箱体的使用寿命。
在一些实施例中，抱箍的截面形状为矩形、工字梁形或口子框形。如此，可提升抱箍的结构强度，进一步避免在箱体容置电芯后，箱体在重力方向上产生变形。
在一些实施例中，下部的结构强度大于上部的结构强度。如此，在利用下部从箱体的下方支撑箱体时，可增加下部抵抗破坏的能力，以提升抱箍的使用寿命。

随着科学技术的发展，新能源技术也在不断发展，尤其是电池技术更是得到了长足的发展。电池包括电芯以及用于容置电芯的电池箱。其中，电池箱可在搬运或使用电芯时，避免电芯与其他物体发生碰撞致使电芯损坏。
本发明人注意到，电池箱在容置电芯后，由于电芯重量较重，易使电池箱的箱体在重力方向上产生变形，从而降低电池箱的使用寿命。
为了提升电池箱的使用寿命，申请人研究发现，可在电池箱的箱体容置电芯后，利用抱箍从箱体下方支撑箱体，以避免箱体在重力方向上产生变形，从而提升箱体使用寿命。
基于以上考虑，为了提升电池箱的使用寿命，发明人经过深入研究，设计了一种电池箱，通过抱箍环绕箱体且抱箍的上部位于箱体顶板远离箱体底板的一侧、并与顶板抵接，以及抱箍的下部位于箱体底板远离箱体顶板的一侧、并与底板抵接，以将抱箍设置在箱体上，并在箱体容置电芯且箱体的底板从电芯的下方支撑电芯后，可通过抱箍的下部从箱体的下方支撑箱体，进而避免箱体在重力方向上产生变形，以提升电池箱的使用寿命。
本申请实施例公开的电池箱可以但不限于用于在搬运/使用电芯时保护电芯。其中，容置在电池箱内的电芯可以为二次电池或一次电池；还可以是锂硫电池、钠离子电池或镁离子电池，但不局限于此。电芯可呈圆柱体、扁平体、长方体或其它形状等。
此外，为了使得电芯的外壁面可更好的与箱体的内壁面贴合以避免电芯与箱体的内壁面发生碰撞，从而更好的保护电芯，箱体内用于容置电芯的腔室与电芯的形状相适配。如：在一实施例中，电芯呈长方体形，箱体用于容置电芯的腔室也呈长方体形、且腔室与电芯的各个尺寸均相同。
参见图1至图4。根据本申请的一些实施例，本申请提供了一种电池箱，包括：箱体100，用于容置电芯，箱体100具有顶板111以及与顶板111相对设置的底板112，底板112用于从电芯的下方支撑电芯；至少一抱箍200，抱箍200环绕箱体100，抱箍200包括上部210以及与上部210相对设置的下部220，上部210位于顶板111远离底板112的一侧、并与顶板111抵接，下部220位于底板112远离顶板111的一侧、并与底板112抵接。
箱体100为具有用于放置电芯的腔室的箱子。箱体100的形状可根据电芯的形状做出相应调整，如：当电芯呈长方形时，箱体100也呈长方形。为了降低箱体100的重量，箱体100可为钣金件，其材质可为铁、铝、金属合金等。此外，为了进一步降低箱体100的重量，箱体100的材料也可为热塑性塑料、纤维增强材料、热固性复合材料等，其成型方式可采用注塑、模压等。需要说明的是，当箱体100采用注塑或模压成型时，还可提升箱体100的生产效率。
箱体100的顶板111以及底板112为：当箱体100容置电芯后，箱体100从上到下依次设置的两个板状物，且电芯位于顶板111与底板112之间。即，当箱体100容置电芯后，顶板111与底板112从上到下依次设置，且底板112从电芯的下方支撑电芯。
抱箍200为刚性件。抱箍200的材质可为金属，如:铁、铝、金属合金等，其成型方式可采用挤出成型等。需要说明的是，当抱箍200采用挤出成型时，可提升抱箍200的生产效率。
抱箍200环绕箱体100且抱箍200的上部210与顶板111抵接以及抱箍200的下部220与底板112抵接。在箱体100容置电芯且箱体100的底板112从电芯的下方支撑电芯后，抱箍200的下部120从箱体100的下方支撑箱体100，可避免箱体100在重力方向上产生变形，以提升电池箱的使用寿命。
在一实施例中，抱箍200的数量为两个。在另一实施例中，抱箍200的数量为一个。需要说明的是，本申请并不限制抱箍200的数量。
参见图1与图2。根据本申请的一些实施例，抱箍200还包括第一连接部231以及第二连接部232，上部210包括第一分体211以及第二分体212，第一分体211的一端经由第一连接部231与下部220相连，第二分体212的一端经由第二连接部232与下部220相连，第一分体211远离第一连接部231的一端与第二分体212远离第二连接部232的一端抵接并固定。
第一分体211的一端经由第一连接部231与下部220相连，即第一连接部231的两端分别与第一分体211的一端和下部220中的一者相连；第二分体212的一端经由第二连接部232与下部220相连，即第二连接部232的两端分别与第二分体212和下部220中的一者相连；如此，可使得第一分体211以及第二分体212均与下部220相连。
此时，由于第一分体211以及第二分体212均与下部220相连，因此，将第一分体211远离第一连接部231的一端与第二分体212远离第二连接部232的一端抵接并固定后，即可将抱箍200稳定地固定在箱体100上。
继续参见图1与图2。根据本申请的一些实施例，上部210还包括自第一分体211远离第一连接部231的一端沿远离箱体100的方向弯折延伸的第一固定部233、以及自第二分体212远离第二连接部232的一端沿远离箱体100的方向弯折延伸的第二固定部(图中未示出)，第一固定部233与第二固定部抵接并固定。
通过设置与第一分体211相连的第一固定部233以及设置与第二分体212相连的第二固定部、且第一固定部233与第二固定部抵接并固定，可增加第一分体211与第二分体212固定时的稳定性。
继续参见图1与图2。根据本申请的一些实施例，电池箱还包括：贯穿第一固定部233以及第二固定部、并将第一固定部233与第二固定部固定的第一紧固件(图中未示出)。
如此，可进一步增加第一固定部233与第二固定部固定时的稳定性，从而进一步增加第一分体211与第二分体212固定时的稳定性。具体的，第一紧固件可为具有螺栓以及螺母的紧固件，螺栓的一端穿过第一固定部233与第二固定部并与螺母固定。
需要说明的是，在其他可变更的实施例中，也可不设有第一紧固件，只要可将第一固定部233与第二固定部固定即可；如：在一实施例中，将第一固定部233与第二固定部通过焊接固定。
继续参见图1与图2。根据本申请的一些实施例，抱箍200一体成型。
如此，在将抱箍200固定在箱体100上时，仅需将第一分体211与第二分体212固定在一起即可，从而降低电池箱在组装时的组装步骤，以降低电池箱在组装时的组装成本。
继续参见图1与图2。根据本申请的一些实施例，箱体100包括上盖121以及下箱体122，上盖121具有顶板111，上盖121固定于下箱体122，下箱体122具有底板112。
如此，在将电芯置于箱体100内时，可先将上盖121与下箱体122分离，并将电芯置于上盖121与下箱体122之间后，再将上盖121固定于下箱体122，以使箱体100容置电芯。
参见图3与图4。根据本申请的一些实施例，抱箍200还包括第三连接部241、第四连接部242、第五连接部243以及第六连接部244，第三连接部241与第五连接部243固定，第四连接部242与第六连接部244固定；第三连接部241与第四连接部242相对设置在上部210的两端，第三连接部241、上部210以及第四连接部242依次相连；第五连接部243与第六连接部244相对设置在下部220的两端，第五连接部243、下部220以及第六连接部244依次相连。
第三连接部241、上部210以及第四连接部242依次相连，即上部210的两端分别与第三连接部241的一端和第四连接部242的一端中的一者相连；第五连接部243、下部220以及第六连接部244依次相连，即下部220的两端分别与第五连接部243的一端以及第六连接部244的一端中的一者相连。
由于第三连接部241、上部210以及第四连接部242依次相连，第五连接部243、下部220以及第六连接部244依次相连，因此，在将第三连接部241与第五连接部243固定且第四连接部242与第六连接部244固定后，即可确保抱箍200的上部210以及下部220稳定地固定在箱体100上。
继续参见图3与图4。根据本申请的一些实施例，抱箍200还包括自第三连接部241远离上部210的一端沿远离第四连接部242的方向弯折延伸的第一延伸部245、以及自第五连接部243远离下部220的一端沿远离第六连接部244的方向弯折延伸的第二延伸部246；第一延伸部245与第二延伸部246固定。
由于第一延伸部245与第三连接部241相连，第二延伸部246与第五连接部243相连，因此，通过第一延伸部245与第二延伸部246固定，可增加第三连接部241与第五连接部243固定时的稳定性。
在一实施例中，抱箍200还包括自第四连接部242远离上部210的一端沿远离第三连接部241的方向弯折延伸的第三延伸部247、以及自第六连接部244远离下部220的一端沿远离第五连接部243的方向弯折延伸的第四延伸部248；第三延伸部247与第四延伸部248固定。
由于第三延伸部247与第四连接部242相连，第四延伸部248与第六连接部244相连，因此，通过第三延伸部247与第四延伸部248固定，可增加第四连接部242与第六连接部244固定时的稳定性。
继续参见图3与图4，并同时参见图5。根据本申请的一些实施例，箱体100包括上盖121以及下箱体122，上盖121具有顶板111以及与顶板111固定的第一法兰131，下箱体122具有底板112以及与底板112固定的第二法兰132，第一法兰131与第二法兰132固定；第一延伸部245位于第一法兰131远离第二法兰132的一侧，第二延伸部246位于第二法兰132远离第一法兰131的一侧；第一延伸部245以及第二延伸部246固定，并夹持第一法兰131以及第二法兰132。

由于第一延伸部245与第二延伸部246夹持第一法兰131以及第二法兰132，且第一延伸部245与第二延伸部246固定，因此，可增加第一法兰131与第二法兰132固定时的稳定性以及第一法兰131与第二法兰132之间的密封性。
在一实施例中，抱箍200设有第三延伸部247以及第四延伸部248，第三延伸部247位于第一法兰131远离第二法兰132的一侧，第四延伸部248位于第二法兰132远离第一法兰131的一侧；第三延伸部247以及第四延伸部248固定，并夹持第一法兰131以及第二法兰132。如此，可进一步增加第一法兰131与第二法兰132固定时的稳定性以及第一法兰131与第二法兰132之间的密封性。
继续参见图3至图5。根据本申请的一些实施例，电池箱还包括：第二紧固件(图中未示出)；第二紧固件依次贯穿第一延伸部245、第一法兰131、第二法兰132以及第二延伸部246，并将第一延伸部245与第二延伸部246固定。
如此，可进一步增加第一延伸部245与第二延伸部246固定时的稳定性，从而进一步增加第一法兰131与第二法兰132固定时的稳定性以及第一法兰131与第二法兰132之间的密封性。具体的，第二紧固件可为具有螺栓以及螺母的紧固件，螺栓的一端穿过第一延伸部245、第一法兰131、第二法兰132以及第二延伸部246并与螺母固定。此外，第二紧固件还可设有置于第一延伸部245与第二延伸部246之间的垫片，从而进一步增加第一延伸部245与第二延伸部246固定时的稳定性。
需要说明的是，在其他可变更的实施例中，也可不设有第二紧固件，只要可将第一延伸部245与第二延伸部246固定即可；如：在一实施例中，将第一延伸部245与第二延伸部246通过焊接固定。
继续参见图3至图5。根据本申请的一些实施例，第一延伸部245和/或第二延伸部246设有用于与挂载件固定的安装块。
如此，当需将电池箱与挂载件固定时，可通过抱箍200的安装块与挂载件固定，从而在电池箱与挂载件固定时，增加抱箍200的下部220对箱体100的支撑力。在一个例子中，安装块上设有安装孔，以便于安装块与挂载件固定。在一个例子中，第一延伸部245和第二延伸部246均设有用于与挂载件固定的安装块。
在一实施例中，当需将容置有电芯的电池箱固定于车辆上时，挂载件为车辆的挂载结构，通过抱箍200的安装块与挂载件固定，可增加抱箍200的下部220对箱体100的支撑力，进一步避免箱体产生变形。
此外，箱体100也可设有用于与挂载件固定的第一安装部(图中未示出)和/或第二安装部141，第一安装部自第一法兰131外缘沿远离第一法兰131的方向凸伸，第二安装部141自第二法 兰132外缘沿远离第二法兰132的方向凸伸。在一个例子中，箱体100仅设有第二安装部141而不设有第一安装部。在又一个例子中，箱体100设有第一安装部和第二安装部141。
继续参见图3与图4。根据本申请的一些实施例，箱体100表面具有凹槽150，抱箍200的至少部分卡设与凹槽150内。
如此，在将抱箍200设置在箱体100上后，可避免抱箍200与箱体100之间发生相对移动，以及减少抱箍200突出于箱体100的体积。
继续参见图3与图4。根据本申请的一些实施例，凹槽150包括设置在顶板111的第一凹槽151、以及设置在底板112的第二凹槽(图中未示出)，第一凹槽151以及第二凹槽沿相互靠近的方向凹陷；上部210的至少部分卡设于第一凹槽151内；下部220的至少部分卡设于第二凹槽内。如此，即可在将抱箍200设置在箱体100上后，避免抱箍200与箱体100之间发生相对移动。
继续参见图3与图4。根据本申请的一些实施例，箱体100还具有两相对设置且均与顶板111以及底板112相连的侧板113；凹槽150包括分别位于一侧板113、且沿相互靠近的方向凹陷的两个第三凹槽152；抱箍100卡设于两个第三凹槽152内。如此，也可在将抱箍200设置在箱体100上后，避免抱箍200与箱体100之间发生相对移动。
继续参见图3与图4。根据本申请的一些实施例，电池箱还包括：缓冲垫(图中未示出)；箱体100的形状为长方体或类长方体；缓冲垫位于箱体100与抱箍200之间、并处于箱体100的转角处。
如此，可避免抱箍200与箱体100转角处发生摩擦，以提升抱箍200以及箱体100的使用寿命。其中，类长方体为类似于长方体的形状，如：在一实施例中，箱体100设有第一法兰131以及第二法兰132，去除第一法兰131以及第二法兰132后的箱体100的形状为长方体，而由于箱体100设有第一法兰131以及第二法兰132，因此，箱体100的形状为类长方体。
在一实施例中，缓冲垫为硅胶缓冲垫。在另一实施例中，缓冲垫为泡棉缓冲垫。
继续参见图1至图4。根据本申请的一些实施例，抱箍200的截面形状为矩形、工字梁形或口子框形。如此，可提升抱箍200的结构强度，进一步避免在箱体100容置电芯后，箱体100在重力方向上产生变形。此外，还可在抱箍200上设有加强筋，从而更进一步提升抱箍100的结构强度。
继续参见图3至图5。下部220的结构强度大于上部210的结构强度。如此，在利用下部220从箱体100的下方支撑箱体100时，可增加下部220抵抗破坏的能力，以提升抱箍200的使用寿命。在一实施例中，下部220的截面面积大于上部210的截面面积，如此，即可使得下部220的结构强度大于上部210的结构强度。
根据本申请的一些实施例，参见图1与图2，本申请提供了一种电池箱，包括：箱体100以及一体成型的抱箍200；箱体100包括上盖121以及下箱体122，上盖121具有顶板111，上盖121固定于下箱体122，下箱体122具有底板112；抱箍200环绕箱体100，抱箍200包括上部210以及与上部210相对设置的下部220，上部210与顶板111抵接，下部220与底板112抵接；上部210包括第一分体211、第二分体212、第一固定部233以及第二固定部，抱箍200还包括连接第一分体211和下部220的第一连接部231以及连接第二分体212和下部220的第二连接部232；第一固定部233与第二固定部抵接并固定，第一紧固件将第一固定部233与第二固定部固定。
根据本申请的一些实施例，参见图3至图5，本申请提供了一种电池箱，包括：箱体100、抱箍200以及位于箱体100与抱箍200之间的缓冲垫；箱体100包括上盖121以及下箱体122，上盖121具有顶板111以及与顶板111固定的第一法兰131，下箱体122具有底板112以及与底板112固定的第二法兰132，第一法兰131与第二法兰132固定，箱体100表面还设有用于卡设抱箍200的凹槽150；抱箍200包括依次相连的第三连接部241、上部210以及第四连接部242，依次相连的第五连接部243、下部220以及第六连接部244，与第三连接部241相连的第一延伸部245，以及与第五连接部243相连的第二延伸部246，第一延伸部245和/或第二延伸部246设有用于与挂载件固定的安装块，第二紧固件将第一延伸部245与第二延伸部246固定。
