Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery charging equipment, and particularly relates to a charging bracket for a lithium battery pack. Background Art

[0002] A lithium battery pack is an energy storage unit composed of multiple lithium battery monomers combined in series, parallel or series-parallel connection. By connecting in series, the output voltage can be increased (for example, connecting 3.7V monomers in series to form a 48V system), and by connecting in parallel, the total capacity can be increased (for example, connecting 50Ah monomers in parallel to form a 200Ah battery pack). This combination method can meet the voltage level (12V / 24V / 48V, etc.) and capacity requirements (from a few ampere-hours to hundreds of ampere-hours) of different application scenarios, and is widely used in new energy vehicles, energy storage systems, power tools and other fields. The batteries are made of single cells. At the production end, the batteries need to be individually charged one by one. The charging bracket is made of a metal frame or engineering plastics to ensure the stability of the battery during charging. However, it still has the following disadvantages in actual use:

[0003] 1. When a lithium battery monomer is being charged, the lithium battery monomer is directly installed in the groove of the bracket and needs to be charged individually one by one. During operation, the monomer needs to be pressed into the groove, and then taken out one by one after charging is completed. The picking and placing efficiency is low, and the picking and placing of the lithium battery monomer during operation is not convenient enough.

[0004] 2. Secondly, during the charging process, the lithium battery monomers are usually charged in a single layer. Usually, lithium battery charging in production is carried out in batches. The structure of charging in a single layer cannot effectively utilize the space, resulting in a relatively large space cost for charging. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a charging bracket for a lithium battery pack, which solves the problems that in the single-cell charging of the charging bracket for a lithium battery pack, the picking and placing of the single cell is not convenient enough, and the batteries cannot be stacked for charging during charging, resulting in a relatively large space cost.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

[0007] The utility model relates to a charging bracket for a lithium battery pack, which comprises a support panel, a wiring sleeve and a movable frame. A plurality of movable openings penetrating through the support panel are symmetrically arranged at the top of the support panel with the horizontal center line as the axis of symmetry. A movable frame is movably connected in the corresponding movable openings at both sides inside the support panel. The movable frame is integrally arranged in a U shape, and support rings are fixed at both ends of the movable frame. Wiring sleeves are fixed at both long sides of the top of the support panel. A socket is penetrated through each support ring along the central axis. A plurality of arc-shaped power connection plates are fixed on the inner side wall of the wiring sleeve at equal intervals. During operation, the support panel movably connects the movable frame therein. During the operation of the support panel, the support panel provides support for the wiring sleeve. During the operation of the wiring sleeve, the arc-shaped power connection plates for charging the battery are fixedly connected together. The sockets on the support rings fixed at both ends of the movable frame are movably connected to the battery, and the battery is installed on the support panel.

[0008] Furthermore, support columns are fixed at both short sides of both sides of the support panel. A support frame is jointly fixed at the bottom ends of the four support columns on the outer side of the same support panel, and the support columns on the support panel are supported on the support frame.

[0009] Furthermore, legs are fixed at the four corners of the bottom of the support frame. An insertion socket is opened at the center of the top end of each support column. The legs below the upper support panel are inserted into the insertion sockets at the top ends of the support columns of the lower support panel below to complete the stacking support arrangement of the two support panels.

[0010] Furthermore, one side of both wiring sleeves close to the center of the support panel is open, and electrode plates are fixed at the inner bottoms of both wiring sleeves. The electrode plates supply power to the arc-shaped power connection plates.

[0011] Furthermore, the arc-shaped parts of the arc-shaped power connection plates extend out of the opening parts of the wiring sleeves, and each arc-shaped power connection plate in the same wiring sleeve corresponds to the support ring at the same-side end of all movable frames in the support panel one by one. The top ends of the arc-shaped power connection plates are fixed on the inner side wall of the wiring sleeve, and the bottom ends are fixed on the sides of the electrode plates. The arc-shaped power connection plates are conductive by being fixed on the sides of the electrode plates, and thus supply power to the battery electrodes.

[0012] Furthermore, one end of the electrode plate penetrates through and extends out of the wiring sleeve, and a power connection ear plate is fixed at the end of the electrode plate extending out of the wiring sleeve. An installation hole is vertically penetrated through the power connection ear plate. After the electrode plate extends out of the wiring sleeve, the installation hole on the power connection ear plate is connected to an external power connection structure.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model solves the problem that it is not convenient enough to take and place single cells during the single-cell charging of the lithium battery pack charging bracket by setting a support panel, a wiring sleeve and a movable frame. After the support panel is set up, the two electrode installation positions of the line connector for external charging are respectively installed on the electrode plates immediately. During the operation, when power is connected to the electrode plates and a battery is installed, the movable frame is directly pushed upwards to drive the support ring to rise. After the support ring rises, the battery is inserted into the socket openings on the two support rings of the same movable frame, and the positions of the battery electrodes are determined. Then, the movable frame is pulled downwards, causing the battery to descend, and the two electrodes of the battery are respectively pressed against the two arc-shaped power connection plates to charge the battery. After charging for a period of time, the movable frame is pushed again to move the battery away from the wiring sleeve, and then the battery is removed to complete the operation, making it more convenient to take and place single cells for charging.

[0015] 2. The utility model solves the problem of large space cost due to the inability to stack batteries for charging by setting a support panel. When it is necessary to stack and arrange the support panels for battery charging operations, first, one support panel is placed with the end having the wiring sleeve facing upwards, and the legs are supported on the working plane. Then, another support panel is taken, and the legs at the bottom of the support frame at the bottom of this support panel are aligned with the socket openings at the top of the support columns on the already placed support panel until the support frame is supported on the top of the support columns. The two support panels and their attached structures are stacked together, facilitating the stacked support charging of the batteries and reducing the space cost of lithium battery charging.
