Description

Technical Field

[0001] The utility model belongs to the technical field of automotive auxiliary accessories, and relates to a storage device, in particular to a storage device for the back of an automotive seat. Background Technique

[0002] With the development of the economy, automobiles have become important means of transportation in people's daily lives. However, existing vehicles do not have a dedicated device for storing small items, and people often carry items such as mobile phones and tablet computers when traveling. Ordinary storage devices will shake during the driving of the vehicle, especially when the road conditions are poor, the shaking is more obvious;

[0003] Especially for the rear passengers of taxis and online car-hailing services, it is quite laborious to hold mobile phones and tablet computers for a long time by themselves, and there is also a lack of a small table for placing items. In addition, there is a lack of storage space for umbrellas and cold drinks of passengers on rainy days, and it is easy to splash water inside the vehicle. There is also a lack of storage space for tissues and garbage bags. Traditional storage devices far from meet people's needs.

[0004] After retrieval, as disclosed in a Chinese patent document a storage device for an automotive seat [Application No.: 201922277099.0; Publication No.: CN211543337U]. This storage device includes an expansion mechanism, and a placement rack is fixedly connected to the top of the expansion mechanism. The expansion mechanism includes a fixed block fixed to the bottom of the placement rack and a contraction shell sliding on the surface of the fixed block. A contraction cavity adapted to the fixed block is provided on the right side of the contraction shell. A slot is provided in the inner cavity of the top of the fixed block, and a fixed rod is fixedly connected to the inner cavity of the slot. The fixed block and the contraction shell are movably connected by a spring.

[0005] Although through the setting of the expansion mechanism in this utility model, when installed, the expansion mechanism is squeezed by a narrow space, the fixed block will contract into the inner cavity of the contraction shell, reducing the thickness of the expansion mechanism, and it is easier for the user to insert the expansion mechanism into a narrow space, so as to achieve the purpose of convenient installation. However, the storage device cannot quickly switch the usage state, has a small applicable range, and poor storage function.

[0006] Based on this, we propose a storage device for the back of an automotive seat, which can be stably installed on the backs of various automotive seats, freely switch the usage state, has a wide applicable range, a large storage space, is convenient for storage, and has a variety of storage types.
