Description

Technical Field

[0001] This utility model relates to the field of battery maintenance equipment technology, and in particular to a maintenance framework for commercial vehicle power batteries. Background Technology

[0002] Power batteries will gradually lose power due to self-discharge during storage. Therefore, the stored batteries need to be recharged every 1-2 months to maintain power balance and avoid over-discharge affecting battery capacity and shortening battery life.

[0003] Commercial vehicles typically require multiple power batteries connected in series or parallel. These power batteries are large in size and numerous, and during battery maintenance, they need to be laid flat on the ground. The connecting harnesses between the batteries are long and waste a lot of battery maintenance space, resulting in increased battery maintenance costs. Utility Model Content

[0004] To address the problems of existing technologies, this utility model provides a maintenance frame for a commercial vehicle power battery, comprising: multiple U-shaped frames;

[0005] The U-shaped frame includes: a crossbeam and two supports vertically connected to both ends of the crossbeam;

[0006] Multiple longitudinal beams connect the crossbeams of two adjacent U-shaped frames;

[0007] The bottom of each support is connected to a caster wheel;

[0008] The base plate is placed on top of the multiple U-shaped frames.

[0009] Furthermore, a reinforcing beam connects the supports of two adjacent U-shaped frames.

[0010] Furthermore, a first diagonal brace connects the crossbeams and supports of each of the U-shaped frames.

[0011] Furthermore, the outermost two U-shaped frames are connected to the corresponding longitudinal beams by second diagonal braces.

[0012] Furthermore, the caster wheel is a self-locking type.

[0013] Furthermore, the length of the crossbeam is greater than the maximum width of the battery pack and the battery pack base.

[0014] Furthermore, the height of the support is greater than the sum of the heights of the individual battery pack and the battery pack base.

[0015] The beneficial effects of the technical solution provided by this utility model are as follows: This utility model sets up multiple U-shaped frames, each U-shaped frame including a crossbeam and two supports vertically connected to both ends of the crossbeam. Multiple longitudinal beams connect the crossbeams of two adjacent U-shaped frames, connecting the multiple U-shaped frames into an integral frame. The bottom of each support is connected to a caster wheel. The base plate is placed on top of the multiple U-shaped frames. In use, the integral frame can accommodate one battery, and another battery is placed on top of the base plate. The two batteries are placed vertically, which not only shortens the length of the wiring harness connecting the two batteries, but also greatly reduces the space required for battery maintenance. Multiple battery systems can be maintained simultaneously in a limited space, which greatly improves the maintenance efficiency of the battery system and reduces the maintenance cost of the battery system.

[0019] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] It should be noted that in this embodiment, the orientation or positional relationship indicated by terms such as "bottom," "top," "left," and "right" is based on the orientation or positional relationship shown in the accompanying drawings. It is used only for the convenience of describing this application and for simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0022] It should also be noted that, in this embodiment, unless otherwise explicitly specified and limited, the terms "set" and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0023] See Figures 1-2 A commercial vehicle power battery maintenance frame includes multiple U-shaped frames arranged in sequence. In this embodiment, five U-shaped frames are used as an example for illustration. Each U-shaped frame includes a crossbeam 1 and two supports 3 vertically connected to both ends of the crossbeam 1. Multiple longitudinal beams 2 are connected between the crossbeams 1 of two adjacent U-shaped frames to connect the multiple U-shaped frames into an integral frame. A base plate 7 is placed on the top of the integral frame for placing the battery pack 8 and the battery pack base support 9.

[0024] Among them, the height of support 3 is greater than the sum of the heights of a single battery pack 8 and battery pack base 9, and the length of crossbeam 1 is greater than the maximum width of battery pack 8 and battery pack base 9, so that the entire frame can accommodate a battery pack 8 and battery pack base 9.

[0025] A reinforcing beam 5 connects the supports 3 of two adjacent U-shaped frames. A first diagonal brace 4 connects the crossbeam 1 of each U-shaped frame to the support 3. A second diagonal brace 10 connects the supports 3 of the two outermost U-shaped frames to the corresponding longitudinal beams 2 to strengthen the frame structure.

[0026] The bottom of each support 3 is connected to a caster wheel 6, which is a self-locking caster wheel, making it convenient to move the commercial vehicle power battery maintenance frame.

[0027] For specific usage, please refer to Figure 2 First, place one battery pack 8 and battery pack base 9 on the ground. Then, push the commercial vehicle power battery maintenance frame along the length of the placed battery to the top of the battery pack and lock the universal wheel 6. Then, place another battery pack 8 and battery pack base 9 on the bottom plate 7. If a battery system has more than 3 batteries, multiple commercial vehicle power battery maintenance frames can be used at the same time for placement.

[0028] It is worth noting that the commercial vehicle power battery maintenance frame accommodates one battery inside and places another battery on top of the frame, placing the two batteries vertically. This not only saves the length of the wiring harness connecting the two batteries, but also significantly reduces the space required for battery maintenance. Multiple battery systems can be maintained simultaneously in a limited space, and the battery frame can be moved freely after maintenance, greatly improving the maintenance efficiency of the battery system and reducing the maintenance cost of the battery system.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
