Abstract
Description
Technical Field
[0001] This utility model relates to the field of lithium battery technology, and in particular to a retractable lithium battery handle structure. Background Technology
[0002] With the widespread use of portable energy storage devices and power tools, high-capacity lithium batteries have become the preferred choice for mainstream power sources due to their high energy density and portability. However, these lithium batteries are usually large in size and heavy in weight, and a reliable carrying structure is urgently needed during transportation.
[0003] However, the existing lithium battery handle structure still has obvious shortcomings. Traditional fixed handles are exposed for a long time, which not only makes them prone to collision damage when stacked or installed in equipment, but also occupies extra space and affects the overall compactness.
[0004] Therefore, it is necessary to design a retractable lithium battery handle structure. Utility Model Content
[0005] To overcome the drawback of traditional lithium battery handles being easily damaged by collisions when stacked, the technical problem to be solved is to provide a retractable lithium battery handle structure.
[0006] The technical solution of this utility model is as follows: a retractable lithium battery handle structure, including a lithium battery shell, a storage groove, a baffle, a sliding groove, a sliding shaft, a handle, a locking block, and a buckle. The storage groove is provided in the middle of the rear side of the lithium battery shell. Baffles are fixed to both ends of the storage groove. Sliding grooves are provided in the vertical direction in the middle of the front and rear side walls on both sides of the storage groove. A sliding shaft is slidably installed in the sliding groove. A handle is fixed between the upper ends of the sliding shafts on both sides of the storage groove. A certain number of locking blocks are fixed to the side walls on both sides of the storage groove. The locking blocks are located on the front and rear sides of the handle. Buckles are rotatably installed on the sliding shafts on both sides of the storage groove in the front and rear direction. The buckles are located on the front and rear sides of the handle.
[0007] As a preferred technical solution of this utility model, the handle is made of plastic and its upper surface is provided with a soft anti-slip layer.
[0008] As a preferred technical solution of this utility model, the lower end of the buckle has a hook-shaped structure.
[0009] As a preferred technical solution of this utility model, the side of the locking block facing the buckle is provided with an inclined guide surface, which makes it easy for the buckle to automatically slide into the locking position during the lifting of the handle.
[0010] As a preferred technical solution of this utility model, the handle is flush with the rear side of the lithium battery casing after being stored.
[0011] As a preferred technical solution of this utility model, it also includes a wedge block and a spring. Notches are provided in the middle of the upper side wall on both sides of the storage groove. A wedge block is slidably provided in the notch in the middle of the upper side wall on both sides of the storage groove. A spring is fixed between the wedge block and the bottom surface of the notch. The handle abuts against the wedge block when it is in the storage state.
[0012] Compared with the prior art, the present invention has the following advantages: 1. The present invention provides a storage groove with sliding groove, sliding shaft, card block and buckle on the back side of the lithium battery shell, and with the lifting and automatic locking and unlocking mechanism of the handle, it effectively overcomes the problem that traditional fixed handles are easily damaged by collision and occupy space during long-term exposure during stacking or transportation.
[0013] 2. This utility model sets an inclined guide surface on the card block and adopts a hook-shaped buckle, so that the handle is automatically guided during the upward process and reliably locked after entering the position. It achieves the effect of unfolding and locking without additional operation, and unlocking and retracting by pressing down. The operation is intuitive and labor-saving, and it is especially suitable for efficient use in frequent handling scenarios. Attached Figure Description

[0019] Example: A retractable lithium battery handle structure, such as Figures 1-4As shown, the device includes a lithium battery casing 1, a storage slot 2, a baffle 3, a sliding groove 4, a sliding shaft 5, a handle 6, a locking block 7, and a buckle 8. The storage slot 2 is located in the middle of the rear side of the lithium battery casing 1. Baffles 3 are fixed to both ends of the storage slot 2. Sliding grooves 4 are vertically formed in the middle of the front and rear side walls on both sides of the storage slot 2. A sliding shaft 5 is slidably installed within the sliding groove 4. A handle 6 is fixed between the upper ends of the sliding shafts 5 on both sides of the storage slot 2. A handle 6 is also fixed to the side walls on both sides of the storage slot 2. A certain number of locking blocks 7 are fixedly connected, and the locking blocks 7 are all located on the front and rear sides of the handle 6. The sliding shafts 5 on the left and right sides of the storage groove 2 are rotatably installed with buckles 8 in the front and rear directions. The buckles 8 are located on the front and rear sides of the handle 6. The handle 6 is made of plastic and has a soft anti-slip layer on its upper surface. The lower end of the buckle 8 has a hook-shaped structure. The side of the locking block 7 facing the buckle 8 has an inclined guide surface, which makes it easy for the buckle 8 to automatically slide into the locking position during the lifting of the handle 6. After the handle 6 is stored, it is flush with the rear side of the lithium battery shell 1.
[0020] like Figure 4 As shown, it also includes a wedge block 9 and a spring 10. Notches are provided in the middle of the upper side of the side walls on both sides of the storage groove 2. A wedge block 9 is slidably provided in the notches in the middle of the upper side of the side walls on both sides of the storage groove 2. A spring 10 is fixed between the wedge block 9 and the bottom surface of the notch. The handle 6 abuts against the wedge block 9 when it is in the storage state.
[0021] When the lithium battery needs to be moved, the user holds the handle 6 with both hands and pulls upwards. The handle 6 drives the sliding shafts 5 on both sides to rise vertically along the sliding grooves 4 on the front and rear side walls of the storage slot 2 on the rear side of the lithium battery housing 1. During the ascent, the latches 8 on the front and rear sides of the handle 6 rotate outwards due to the inclined guide surface of the latch 7 facing one side, smoothly passing over the latch 7. When the handle 6 reaches its highest position, the latches 8 return to their original position under their own weight or slight rebound, and the hook-shaped structure at the lower end engages above the latch 7, realizing the unfolding and locking of the handle 6. At this time, the handle 6 is stably suspended behind the lithium battery housing 1, and its soft anti-slip layer provides a comfortable grip and anti-slip effect. At this time, the sliding shafts 5 Located above the wedge block 9, the wedge block 9 extends outward under the action of the spring 10 to provide auxiliary support for the sliding shaft 5. After the transport is completed, the user presses down on the handle 6, causing the buckle 8 to rotate outward again and disengage from the buckle 7. At the same time, the wedge block 9 is squeezed by the sliding shaft 5 and slides into the notch. When the sliding shaft 5 is below the wedge block 9, the wedge block 9 abuts against the handle 6 under the action of the spring 10 until the handle 6 falls back into the storage slot 2. When the handle 6 is fully retracted, its outer contour is flush with the rear side of the lithium battery casing 1. The baffles 3 at both ends of the storage slot 2 limit the left and right displacement of the handle 6 to ensure structural stability. The whole process is simple to operate, reliable to lock, and takes into account portability and compactness.
