本发明涉及一种铝合金电池箱，其包括电池箱上盖和电池箱底盖，电池箱上盖包括底壁、自底壁延伸的环绕底壁的若干侧壁和由底壁和侧壁共同形成的收容腔，电池箱箱盖呈梯形结构，其特征在于：在电池箱底盖内部布置有条形加强筋，条形加强筋通过铆接与电池箱底部连接，在电池箱下盖侧壁的突延处与侧壁之间还设有片状加强筋，片状加强筋以两片为一组设置在侧壁上，多组片状加强筋以一定间隔沿侧壁四周放置。本电池箱通过在电池箱底盖的加强筋处理以保证其强度，底部突出的加强筋也减少了电池与电池箱底盖的接触面积，增加了散热效果的同时，采用该类材料对整体电池箱的重量可大大减轻，其制造成本也相当低廉。

The invention relates to an aluminum alloy battery box, which comprises a battery box upper cover and a battery box bottom cover. The battery box cover has a trapezoidal structure, which is characterized in that: a strip-shaped reinforcing rib is arranged inside the bottom cover of the battery box, and the strip-shaped reinforcing rib is connected to the bottom of the battery box by riveting. There is also a sheet-shaped reinforcing rib between the center and the side wall. The sheet-shaped reinforcing ribs are arranged on the side wall in groups of two, and multiple groups of sheet-shaped reinforcing ribs are placed along the sides of the side wall at certain intervals. The battery box is treated with reinforcing ribs on the bottom cover of the battery box to ensure its strength. The protruding ribs at the bottom also reduce the contact area between the battery and the bottom cover of the battery box and increase the heat dissipation effect. The weight can be greatly reduced and the manufacturing cost is relatively low.

Description

一种铝合金电池箱An aluminum alloy battery box

技术领域：Technical field:

背景技术：Background technique:

电池箱用于容纳电池组和连接外部和电池的引线。 The battery box is used to house the battery pack and the leads connecting the outside and the battery.

市场上常用电池箱为长方形框架结构，边框、底框使用型材焊接，体型大，结构强度低，成本高。  Commonly used battery boxes in the market are rectangular frame structures, and the frame and bottom frame are welded with profiles, which are large in size, low in structural strength, and high in cost. the

发明内容：Invention content:

本发明的目的是提供一种强度及耐腐性高的金属材质的电池箱体。 An object of the present invention is to provide a metal battery case with high strength and corrosion resistance.

本发明所采用的技术方案为：一种铝合金电池箱，其包括电池箱上盖和电池箱底盖，电池箱上盖包括底壁、自底壁延伸的环绕底壁的若干侧壁和由底壁和侧壁共同形成的收容腔，电池箱箱盖呈梯形结构，其特征在于：在电池箱底盖内部布置有加强筋。  The technical solution adopted in the present invention is: an aluminum alloy battery box, which includes a battery box upper cover and a battery box bottom cover, the battery box upper cover includes a bottom wall, a number of side walls surrounding the bottom wall extending from the bottom wall, and a bottom wall extending from the bottom wall. The storage cavity formed by the wall and the side wall together, and the battery box cover has a trapezoidal structure, and the feature is that a reinforcing rib is arranged inside the bottom cover of the battery box. the

    进一步，所述的条形加强筋通过铆接与电池箱底部连接。  Further, the strip-shaped reinforcement is connected to the bottom of the battery box by riveting. the

    进一步，所述的电池箱下盖侧壁的突延处与侧壁之间设有片状加强筋。  Further, a sheet-shaped reinforcing rib is provided between the extension of the side wall of the lower cover of the battery box and the side wall. the

本发明产生的有益效果是：本电池箱采用铝合金制作，通过在电池箱底盖的加强筋处理以保证其强度，底部突出的加强筋也减少了电池与电池箱底盖的接触面积，增加了散热效果的同时，采用该类材料对整体电池箱的重量可大大减轻，仅为其他金属材质的二分之一，而强度及耐腐性高于其他金属材质的箱体；其制造成本也相当低廉。   The beneficial effects produced by the present invention are: the battery box is made of aluminum alloy, and its strength is ensured by the reinforcing ribs on the bottom cover of the battery box. At the same time, the use of this type of material can greatly reduce the weight of the overall battery box, which is only half of other metal materials, and its strength and corrosion resistance are higher than other metal boxes; its manufacturing cost is also quite low . the

附图说明：Description of drawings:

图1为铝合金电池箱底盖的加强筋示意图； Fig. 1 is the schematic diagram of the reinforcing rib of the bottom cover of the aluminum alloy battery box;

图2为本发明的结构示意图。 Fig. 2 is a structural schematic diagram of the present invention.

具体实施方式：Detailed ways:

底面结合附图对本发明做进一步的说明。 The bottom surface will further illustrate the present invention in conjunction with the accompanying drawings.

如图2所示，一种铝合金电池箱，包括电池箱上盖2和电池箱底盖3用于放置电动汽车电池组，整个箱体呈阶梯型结构，便于放置在电动汽车内部，并与电动汽车车身其他部位契合。从图1中可以看出，在电池箱的底盖内侧铆接有条形加强筋1，多块条形加强筋1平行放置在底盖3内侧，保证了电池箱整体强度。条形加强筋本体呈梯形结构，与底盖3结合后突出的加强筋可以减少电池与电池箱底盖3的接触面积，增强了通风性能，增加散热效果。  As shown in Figure 2, an aluminum alloy battery box includes a battery box upper cover 2 and a battery box bottom cover 3 for placing electric vehicle battery packs. The rest of the car body fits. It can be seen from Fig. 1 that a strip-shaped reinforcing rib 1 is riveted inside the bottom cover of the battery box, and multiple strip-shaped reinforcing ribs 1 are placed in parallel on the inside of the bottom cover 3 to ensure the overall strength of the battery box. The body of the bar-shaped reinforcing rib is in a trapezoidal structure, and the protruding reinforcing rib combined with the bottom cover 3 can reduce the contact area between the battery and the bottom cover 3 of the battery box, enhance the ventilation performance, and increase the heat dissipation effect. the

铝合金电池箱侧壁上的片状加强筋4用于增加从侧壁上延伸出的突出部与侧壁的牢固程度，片状加强筋4以两片为一组设置在侧壁上，多组片状加强筋4以一定间隔沿侧壁四周放置，用于更好的与电池箱的上盖2固定，固定方式为使用六角法兰面螺栓连接。  The sheet-shaped reinforcing rib 4 on the side wall of the aluminum alloy battery box is used to increase the firmness of the protrusion extending from the side wall and the side wall. The sheet-shaped reinforcing rib 4 is arranged on the side wall in groups of two, and the Groups of sheet-like reinforcing ribs 4 are placed around the side walls at certain intervals for better fixing with the upper cover 2 of the battery box, and the fixing method is to use hexagonal flange bolts to connect. the

最后说明的是，以上实施例仅用以说明本发明的技术方案而非限制，本领域普通技术人员对本发明的技术方案所做的其他修改或者等同替换，只要不脱离本发明技术方案的精神和范围，均应涵盖在本发明的权利要求范围当中。  Finally, it is noted that the above embodiments are only used to illustrate the technical solution of the present invention without limitation, other modifications or equivalent replacements made by those skilled in the art to the technical solution of the present invention, as long as they do not depart from the spirit and spirit of the technical solution of the present invention All should be included in the scope of the claims of the present invention. the
