[0030] When the foldable inner liner structure of the present application is to be used, the first side panel 2 and the second side panel 3 are bent and perpendicular to the plane of the bottom panel 1, and then the first side panel 2 and the second side panel 3 are fixed with the connecting fixture 4. At this time, one side of the foldable inner liner structure is open and forms a storage space 6 for placing photographic equipment. When the size of the storage space 6 needs to be adjusted, the pocket assembly 5 is opened in the storage space 6 to form a storage compartment 7. At this time, the size of the storage space 6 is changed to facilitate the placement and storage of different types of photographic equipment. The space can be changed according to the user's needs, making it more convenient to use. When the foldable inner liner structure is not needed, it can be spread out flat for storage.

[0031] Specifically, the bottom plate 1, the first side plate 2, the second side plate 3 and the pocket assembly 5 are all filled with cushioning materials. The bottom plate 1, the first side plate 2 and the second side plate 3 have similar structures, and all include an intermediate layer, a protective layer arranged on the outside of the intermediate layer, and a soft layer arranged on the inside of the intermediate layer. The material of the intermediate layer is foamed EVA, the material of the protective layer is polyester Oxford cloth, and the material of the soft layer is polyester velvet. The three materials are formed by hot pressing external force and interlayer adhesive bonding. The protective layer provides a certain degree of tear resistance and surface scratch resistance, and the middle layer and the protective layer provide the main protective performance, which can play a role in cushioning and shock absorption. The velvet fabric of the soft layer provides protection for the surface of the device and a certain degree of anti-collision performance. The three layers of fabric are combined together by hot pressing, and the connection position between the bottom plate 1 and the first side plate 2 and the connection position between the bottom plate 1 and the second side plate 3 are pressed out with a folding path.

[0032] Furthermore, the connecting fixture 4 is folded and disposed on the side of the first side panel 2 or the second side panel 3. After the first side panel 2 and the second side panel 3 are bent perpendicular to the plane of the bottom panel 1, the connecting fixture 4 is bent again and the first side panel 2 and the second side panel 3 are fixed together using the connecting fixture 4. The connecting fixture 4 is provided with a Velcro tape for adhesive fixation, facilitating subsequent disassembly.

[0033] Furthermore, the pocket assembly 5 is made of a flexible material, and the pocket assembly 5 is a trapezoidal flat plate structure. The short bottom edge of the pocket assembly 5 is fixed on the bottom plate 1, the waist side edge of the pocket assembly 5 is fixed on the first side plate 2, and the long bottom edge of the pocket assembly 5 is open.

[0034] Specifically, the pocket assembly 5 is a planar plate-like structure in the shape of an isosceles trapezoid. The short bottom edge of the pocket assembly 5 is fixed to the base plate 1, and the two waist sides of the pocket assembly 5 are respectively fixed to the corresponding first side plate 2. The long bottom edge of the pocket assembly 5 is open. The pocket assembly 5 is provided with a folded edge 51 at a position corresponding to the long edge of the base plate 1. There are two folded edges 51, which divide the pocket assembly 5 into three parts. The middle part of the three parts is a baffle 52, and the two sides of the baffle 52 are connecting parts 53. The baffle 52 can be vertically arranged on the base plate 1. When the pocket assembly 5 is opened, the baffle 52 can be vertically arranged on the base plate 1. The baffle 52 acts as a partition, so that the baffle 52, the base plate 1, the first side plate 2, and the second side plate 3 enclose a storage compartment 7. In this embodiment, the baffle 52 has a three-layer structure, with the middle layer made of foamed EVA and the materials on both sides of the middle layer being polyester velvet. The barrier 52 acts as a partition, dividing the storage space 6. Both contact surfaces of the barrier 52 come into contact with photographic equipment, so they are protected with polyester flannel. The connector 53 is made of flexible fabric, serving as a connection, allowing the strap assembly to be easily opened without the need for EVA foam. The contact surface of the connector 53 with the photographic equipment is covered with polyester flannel to prevent scratches.

[0035] As a variant embodiment, the pocket assembly 5 can also be a triangular planar plate structure, with the two waist sides of the pocket assembly 5 respectively fixed to the corresponding first side panel 2, and the bottom edge of the pocket assembly 5 being open. In this case, the pocket assembly 5 can also be opened to form the storage compartment 7. In this case, the storage compartment 7 has an inverted pyramid space structure with a smaller storage space.

[0036] Furthermore, the pocket assembly 5 is divided into two groups, and the two groups of pocket assembly 5 are symmetrically arranged at the short sides of the bottom plate 1. When the two groups of pocket assembly 5 are expanded, they can form storage compartments 7 respectively, which can divide the storage space 6 into multiple parts, making it convenient to separate and place multiple photographic equipment to avoid collision and scratches.

[0037] Furthermore, a connecting tongue 54 is provided at the opening edge of the barrier portion 52, and the connecting tongue 54 is folded and connected to the barrier portion 52. By providing the connecting tongue 54, the fingers can directly pull the connecting tongue 54 to directly pull up and open the barrier portion 52.

[0038] Specifically, the connecting tongue 54 is made of a flexible fabric material and is set to be the same length as the short side of the base plate 1. The side of the connecting tongue 54 facing the second side plate 3 is provided with a Velcro. When the pocket assembly 5 does not need to be opened, the connecting tongue 54 is adhered to the second side plate 3. The pocket assembly 5 always adheres to the base plate 1 and the first side plate 2. Even if the first side plate 2 and the second side plate 3 are bent, the pocket assembly 5 cannot be opened. When the pocket assembly 5 needs to be opened, the connecting tongue 54 is directly pulled by the fingers to separate the Velcro from the second side plate 3. The connecting tongue 54 is then continued to be pulled until the barrier portion 52 is pulled up and opened. The provision of the connecting tongue 54 makes it convenient for the fingers to directly pull up and open the barrier portion 52.

[0039] In other embodiments, the connecting tongue 54 may be replaced with a drawstring, one end of which is fixed to the opening edge of the barrier portion 52 . In this case, a Velcro strip may be provided at the opening edge of the barrier portion 52 .

[0040] Furthermore, a connecting ear plate 21 is provided on the side of the first side panel 2 away from the bottom panel 1. The connecting ear plate 21 is provided with a Velcro fastener, which is arranged on the side facing away from the storage space 6. After the foldable liner structure is placed in the storage space of the backpack, it can be fixed to the inner cavity of the backpack via the Velcro fastener on the connecting ear plate 21, so that the foldable liner structure is stably fixed in the backpack.

[0041] When the foldable inner liner structure of the present application is to be used, the first side panel 2 and the second side panel 3 are bent and perpendicular to the plane of the bottom panel 1, and then the first side panel 2 and the second side panel 3 are fixed with the connecting fixing member 4. At this time, one side of the foldable inner liner structure is open to form a storage space 6 for placing photographic equipment. When the size of the storage space 6 needs to be adjusted, the pocket assembly 5 is opened in the storage space 6 to form a storage compartment 7. At this time, the size of the storage space 6 is changed to facilitate the placement and storage of photographic equipment of different models. The space can be changed according to the needs of the user, making it more convenient to use.
