  • the pressure strip structure has an inner cavity.
  • the pressure strip structure can achieve a certain buffer deformation through the inner cavity when subjected to external impact, so as to absorb the impact energy of the external force.

  • the second wall is connected to the first wall and together with the first wall forms an inner cavity.
  • the second wall can withstand the impact, while the first wall can distribute stress.

本申请要求于2024年05月30日在中华人民共和国国家知识产权局提交的、申请号为202421212420.1、申请名称为“电池箱体、电池及用电装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及电池技术领域，具体涉及一种电池箱体、电池及用电装置。
背景技术
相关技术中，电池可以包括电池箱体和电池单体。电池箱体可以包括边框、防护板和密封垫。边框设于防护板的一侧，以与防护板围设形成用于容纳电池单体的空间。密封垫抵压于边框和防护板之间，以对边框和防护板的连接位置实现密封。
在球击工况下，防护板会受到球击并产生变形，以挤压密封垫，导致密封垫的密封效果失效。
发明内容
鉴于上述问题，本申请实施例的目的在于：提供一种电池箱体、电池及用电装置，能够改善密封垫的密封效果失效的技术问题。
本申请实施例采用的技术方案是：
第一方面，本申请实施例提供了一种电池箱体，包括：
防护板；
边框，设于防护板的一侧；
密封垫，抵压于边框和防护板之间；
压条结构，包括第一壁，第一壁设于防护板远离密封垫的一侧，第一壁在防护板上的正投影覆盖密封垫在防护板上的至少部分正投影；
第一紧固件，用于沿防护板和边框的分布方向依次穿过第一壁、防护板、密封垫和边框。
本申请实施例提供的电池箱体，通过在防护板远离密封垫的一侧设置压条结构，且压条结构的第一壁在防护板上的正投影覆盖密封垫在防护板上的至少部分正投影，使得在球击等外力冲击工况下，压条结构可以遮挡防护板的与密封垫正对的部分，以替代防护板直接承受球击等外力冲击。这样，通过压条结构承受球击等外力冲击，可以减小防护板的与密封垫正对的部分受到的外力冲击，以减小防护板的与密封垫正对的部分所产生的变形，从而改善防护板所产生的变形导致密封垫过压缩甚至破损的问题。因此，有助于改善密封垫过压缩甚至破损的问题。
此外，第一紧固件的设置，一方面，可以使得密封垫固定于边框和防护板之间，从而使得密封垫可以稳定地实现边框和防护板的连接位置的密封效果；另一方面，可以使得压条结构固定于防护板，从而可以稳定地改善密封垫的密封效果失效的问题。
在一些实施例中，压条结构设有内腔。
通过压条结构设置内腔，使得压条结构在承受外力冲击的情况下，可以通过内腔实现一定的缓冲变形，以吸收外力冲击能量。
在一些实施例中，压条结构还包括：
第二壁，连接于第一壁，且与第一壁围设形成内腔。
通过采用上述技术方案，使得在球击等外力冲击工况下，第二壁可以承受球击等外力冲击，第一壁可以分散应力。在第一壁分散应力的作用下，防护板的与密封垫正对的部分受到的外力冲击较为均衡，密封垫受到的外力冲击也随之均衡。这样，可以改善防护板的与密封垫正对的部分局部受到较大的外力冲击的问题，以改善防护板局部产生较大变形导 致密封垫局部过压缩甚至破损的问题。
在一些实施例中，压条结构还包括第三壁，第三壁连接于第二壁，且与第一壁、第二壁围设形成内腔；在防护板和边框的分布方向上，第三壁与第一壁间隔且相对设置。
这样，可以改善防护板的与密封垫正对的部分局部受到较大的外力冲击的问题，以改善防护板局部产生较大变形导致密封垫局部过压缩甚至破损的问题，改善密封垫的密封效果失效问题。
在一些实施例中，第三壁在防护板上的正投影覆盖密封垫在防护板上的至少部分正投影。
这样，一方面，使得压条结构可以通过空腔对外力冲击实现一定的缓冲变形；另一方面，第一壁和第二壁可以较好地分散应力。
在一些实施例中，防护板包括中间部和连接于中间部外周的外围部，密封垫抵压于外围部和边框之间，第一壁设于外围部远离密封垫的一侧，第一紧固件穿设于外围部；
电池箱体设有第一截面，第一截面平行于防护板和边框的分布方向，且穿过第一紧固件；
在第一截面上，沿外围部和中间部的分布方向，密封垫的位于第一紧固件靠近中间部的部分为内密封部，密封垫的位于第一紧固件远离中间部的部分为外密封部；
其中，第一壁在外围部上的正投影覆盖内密封部在外围部上的至少部分正投影和外密封部在外围部上的至少部分正投影。
这样，在第一壁可以分散应力的作用下，使得外围部的与内密封部正对的部分受到的外力冲击、外围部的与外密封部正对的部分受到的外力冲击均较为均衡，从而有助于改善密封垫的外密封部局部过压缩甚至破损、内密封部局部过压缩甚至破损的问题，以改善密封垫的密封效果失效的问题。
在一些实施例中，内密封部在外围部上的正投影位于第一壁在外围部上的正投影内。
如此设置，使得第一壁可以分散应力，从而使得压条结构受到外力冲击的情况下，内密封部受到的外力冲击十分均衡，内密封部基本不会受到局部受到外力冲击。这样，可以较大程度地改善内密封部局部过压缩甚至变形的问题，使得密封垫具有较佳的密封效果。
在一些实施例中，电池箱体还包括第二紧固件，第二紧固件连接于边框，第一紧固件依次穿过第一壁、防护板、密封垫和第二紧固件。
这样使得压条结构、防护板、密封垫和边框通过第一紧固件、第二紧固件实现固定。
在一些实施例中，沿防护板和边框的分布方向，第二紧固件的至少部分伸出于边框靠近防护板的一端外，且抵靠于防护板；密封垫围设于第二紧固件的外周。
通过第二紧固件抵靠于防护板，使得第二紧固件可以分散应力，且可以对防护板实现一定的限位，从而可以减小密封垫受到的外力冲击，且可以使得密封垫受到的外力冲击十分均衡。这样，有助于改善密封垫局部过压缩甚至破损的问题，以提高密封垫的密封效果。
在一些实施例中，第二紧固件包括沿防护板和边框的分布方向连接的第二限位部和第二紧固部，第二紧固部设于边框内；沿防护板和边框的分布方向，第二限位部位于边框靠近防护板的一端，第二限位部远离防护板的一端抵靠于边框。
如此设置，使得第二紧固件可以沿第一方向限位于边框上，便于第二紧固件牢靠地固定于边框上。
在一些实施例中，第一紧固件包括沿防护板和边框的分布方向连接的第一限位部和第一紧固部，第一紧固部依次穿设于第一壁、防护板、密封垫和第二紧固件，且连接于第二紧固件；第一限位部位于第一壁远离防护板的一侧，且抵靠于第一壁远离防护板的一侧。
如此设置，使得第一紧固件能够将压条结构、防护板、密封垫和边框牢靠固定。
在一些实施例中，沿防护板和边框的分布方向，压条结构远离防护板的一侧设有容纳槽，第一壁设于容纳槽的槽底；
第一紧固件的部分容纳于容纳槽内，且沿防护板和边框的分布方向，压条结构远离防 护板的一侧超出于第一紧固件远离边框的一端外。
通过在压条结构远离防护板的一侧设有容纳槽，使得第一紧固件可以从容纳槽沿第一方向依次穿过第一壁、防护板、密封垫和边框，便于电池箱体的边框、密封垫、防护板和压条结构实现相互固定。
通过在第一方向上，压条结构远离防护板的一侧超出于第一紧固件远离边框的一端外，使得压条结构可以对第一紧固件实现一定的防护效果。基于此，在球击等外力冲击下，第一紧固件在压条结构的防护下不会直接被外力冲击，从而可以改善第一紧固件直接被外力冲击导致第一紧固件处破损，甚至导致边框、防护板开裂的问题，以改善电池箱体的密封效果失效的问题。
在一些实施例中，防护板包括中间部和连接于中间部外周的外围部，密封垫抵压于外围部和边框之间，第一壁设于外围部远离密封垫的一侧，第一紧固件穿设于外围部；
电池箱体设有第一截面，第一截面平行于防护板和边框的分布方向，且穿过第一紧固件；
在第一截面上，沿外围部和中间部的分布方向，容纳槽贯通压条结构远离中间部的一端。
如此设置，使得在外围部和中间部的分布方向上，第一壁远离中间部的边缘可以尽量靠近第一紧固件，从而能够减小第一壁在外围部和中间部的分布方向上的尺寸，以减小压条结构的体积和重量。
在一些实施例中，压条结构设有内腔，内腔和容纳槽之间设有连接于第一壁的第四壁。
通过第四壁连接于第一壁，使得第四壁也可以进行分散应力，从而有助于使得防护板的与密封垫正对的部分受到的外力冲击较为均衡，密封垫受到的外力冲击也随之较为均衡，这样有助于改善密封垫局部过压缩甚至破损的问题。
在一些实施例中，沿防护板和边框的分布方向，边框靠近防护板的一端设有支撑部，支撑部抵靠于防护板。
通过边框的支撑部抵靠于防护板，使得边框可以分散应力，且可以对防护板实现一定的限位，从而可以减小密封垫受到的外力冲击，且可以使得密封垫受到的外力冲击十分均衡。这样，有助于改善密封垫局部过压缩甚至破损的问题，以提高密封垫的密封效果。
在一些实施例中，防护板包括中间部和连接于中间部外周的外围部，密封垫抵压于外围部和边框之间，压条结构设于外围部远离密封垫的一侧；
其中，沿防护板和边框的分布方向，中间部远离边框的一侧齐平或超出于压条结构远离边框的一侧。
如此设置，使得中间部远离边框的一侧超出或齐平于压条结构远离密封垫的一侧，这样可以减小压条结构被外力冲击的概率，从而有助于在一定程度上改善密封垫的密封效果。

沿第一方向Z，电池箱体20的第二部分22设于边框212远离防护板211的一端，且第二部分22和防护板211正对设置。这样，防护板211、边框212和第二部分22围设形成电池箱体20的内部空间。
其中，防护板211可以构成电池箱体20的内部空间的底壁，第二部分22可以构成电池箱体20的内部空间的顶壁。边框212是指电池箱体20的框架，可以构成电池箱体20的内部空间的周壁。

压条结构214是指设于防护板211上的用于抵抗外力，以减缓防护板211受到外力冲击而变形的结构。其中，第一壁2141为压条结构214的实体壁。
沿第一方向Z，压条结构214的第一壁2141设于防护板211远离密封垫213的一侧。这样，使得在第一方向Z上，边框212、密封垫213、防护板211和压条结构214的第一壁2141依次分布。
第一壁2141在防护板211上的正投影，是指第一壁2141沿第一方向Z投射至防护板211上的投影。其中，第一壁2141和防护板211沿第一方向Z正对设置。
密封垫213在防护板211上的至少部分正投影，是指密封垫213沿第一方向Z投射至防护板211上的投影的至少部分。其中，密封垫213和防护板211沿第一方向Z正对设置。
第一壁2141在防护板211上的正投影覆盖密封垫213在防护板211上的至少部分正投影，使得防护板211的与密封垫213沿第一方向Z正对的部分，也与第一壁2141沿第一方向Z正对设置，从而使得第一壁2141的至少部分和密封垫213的至少部分通过防护板211沿第一方向Z正对设置。
第一紧固件215是指用于进行紧固作用的部件，例如螺栓、铆钉等。
沿第一方向Z，第一紧固件215依次穿过第一壁2141、防护板211、密封垫213和边框212，可以将第一壁2141、防护板211、密封垫213和边框212固定起来，使得第一壁2141、防护板211、密封垫213和边框212通过第一紧固件215实现固定。
第一紧固件215依次穿过第一壁2141、防护板211、密封垫213和边框212，且第一紧固件215至少固定于边框212，使得第一壁2141、防护板211、密封垫213和边框212固定起来。作为一个示例，边框212上设有下文涉及的第二紧固件216，第一紧固件215固定于设于边框212上的第二紧固件216，以间接地固定于边框212。

具体地，通过第一壁2141设于防护板211远离密封垫213的一侧，且第一紧固件215依次穿过第一壁2141、防护板211、密封垫213和边框212，使得第一壁2141通过第一紧固件215固定于防护板211的与密封垫213正对的部分。这样，使得第一壁2141可以分散应力，以使防护板211的与密封垫213正对的部分受到的外力冲击较为均衡，密封垫213受到的外力冲击也可随之均衡。这样，可以改善防护板211的与密封垫213正对的部分局部受到较大的外力冲击的问题，以改善防护板211局部产生较大变形导致密封垫213局部过压缩甚至破损的问题，提高密封垫213的密封效果。
此外，第一紧固件215的设置，一方面，可以使得密封垫213固定于边框212和防护板211之间，从而使得密封垫213可以稳定地实现边框212和防护板211的连接位置的密封效果；另一方面，可以使得压条结构214固定于防护板211，从而可以稳定地改善密封垫213的密封效果失效的问题。

通过压条结构214设置内腔201，使得压条结构214在承受外力冲击的情况下，可以通过内腔201实现一定的缓冲变形，以吸收外力冲击能量。因此，可以减小防护板211受到的外力冲击，以减小防护板211的与密封垫213正对的部分所产生的变形，进而可以较佳地改善防护板211所产生的变形导致密封垫213过压缩甚至破损的问题，以提高密封垫213的密封效果。

通过采用上述技术方案，使得在球击等外力冲击工况下，第二壁2142可以承受球击等外力冲击，第一壁2141可以分散应力。在第一壁2141分散应力的作用下，防护板211的与密封垫213正对的部分受到的外力冲击较为均衡，密封垫213受到的外力冲击也随之均衡。这样，可以改善防护板211的与密封垫213正对的部分局部受到较大的外力冲击的问题，以改善防护板211局部产生较大变形导致密封垫213局部过压缩甚至破损的问题。

第三壁2143是指压条结构214的实体壁。
作为一个示例，沿第一方向Z，第三壁2143连接于第二壁2142远离第一壁2141的一端。
通过第三壁2143和第一壁2141间隔且相对设置，使得在球击等外力冲击工况下，第三壁2143可以先承受外力冲击，并进行一定的缓冲变形，从而使得压条结构214可以通过空腔吸收外力冲击能量，以减小防护板211受到的外力冲击，减小密封垫213受到的外力冲击。并且，第一壁2141和第二壁2142可以分散应力，从而可以使得防护板211的与密封垫213正对的部分受到的外力冲击较为均衡，密封垫213受到的外力冲击也可随之均衡。这样，可以改善防护板211的与密封垫213正对的部分局部受到较大的外力冲击的问题，以改善防护板211局部产生较大变形导致密封垫213局部过压缩甚至破损的问题，改善密封垫213的密封效果失效问题。

通过采用上述技术方案，使得第三壁2143可以遮挡防护板211的与密封垫213正对的部分以及第一壁2141，从而可以承受球击等外力冲击。这样，一方面，使得压条结构214可以通过空腔对外力冲击实现一定的缓冲变形；另一方面，第一壁2141和第二壁2142可以较好地分散应力。如此，可以较大程度地改善防护板211的与密封垫213正对的部分局部受到较大的外力冲击的问题，以改善防护板211局部产生较大变形导致密封垫213局部过压缩甚至破损的问题，改善密封垫213的密封效果失效问题。

具体地，沿外围部2112和中间部2111的分布方向，内密封部2131和外密封部2132分别位于第一紧固件215的相对两侧。沿第一方向Z，内密封部2131抵压于边框212和外围部2112之间，外密封部2132抵压于边框212和外围部2112之间。这样，使得密封垫213可以围设于第一紧固件215的外周，且抵压于边框212和外围部2112之间，从而可以较好地实现边框212和外围部2112之间的密封效果。
