Technical Field

[0001] The utility model relates to the field of storage boxes, in particular to an aircraft storage box with a gas spring supporting device. Background Art

[0002] On aircraft, storage compartments are used to store essential life-saving equipment, such as life rafts, emergency equipment, and supplies. As an integral part of the aircraft interior, their design and functionality are crucial, ensuring rapid access in the event of a sudden ditching. For example, a life raft stored in a storage compartment can weigh up to 50 kg. Opening and closing the compartment can significantly impact the structure, further increasing the risk of damage. Therefore, they must possess sufficient load-bearing capacity and sealing properties. Traditional aircraft storage compartment designs often neglect cushioning during the opening and closing process, making them difficult to open and close when loaded with heavy objects, compromising the overall safety of the aircraft. Utility Model Content

[0003] Purpose of the utility model: The purpose of this application is to provide an aircraft storage box with a gas spring support device, which has a solid structure, a strong load-bearing capacity for storing heavy objects such as life rafts, high safety performance, and is easy to open and use quickly.

The static box includes a static box side wall panel, and the dynamic box includes a dynamic box side wall panel. It also includes a gas spring support device. Two groups of gas spring support devices are respectively arranged on the left and right sides of the storage box. The gas spring support device includes a long gas spring, a short gas spring a, a short gas spring b, a reinforced support, a reinforced base a, and a reinforced base b. The long gas spring is located at the front of the storage box, with the upper end connected to the static box and the lower end connected to the dynamic box. The short gas spring a and the short gas spring b are located at the rear of the storage box. , the reinforced support is fixed on the inner side of the dynamic box side wall panel, the reinforced base a and the reinforced base b are arranged up and down in front of the reinforced support and fixed on the inner side of the static box side wall panel, the front end of the short gas spring a is connected to the reinforced base a, and the rear end is connected to the reinforced support, the front end of the short gas spring b is connected to the reinforced base b, and the rear end is connected to the reinforced support. When the storage box is closed, the short gas spring a forms an initial downward angle with the horizontal line of the storage box, and the initial angle does not exceed 30°. The angle formed between the short gas spring a and the short gas spring b at the rear end does not exceed 30°, and the opening angle of the storage box does not exceed 45°.

[0005] Working principle: The long gas spring, short gas spring a and short gas spring b in a group of gas spring support devices cooperate with each other in extension and contraction. When the storage box is opened, the long gas spring is in a stretched state, and the short gas spring a and short gas spring b are in a contracted state. When the storage box is closed, the long gas spring is in a contracted state, and the short gas spring a and short gas spring b are in a stretched state. This allows the dynamic box to be tightly closed with the static box when closed, and provides good support and cushioning when opened. At the same time, it also enhances the load-bearing capacity of the storage box, and whether the storage box is opened or closed manually or automatically, it can maintain smooth operation.

[0006] Furthermore: the static box also includes a static box front wall plate and a static box top cover plate, the dynamic box also includes a dynamic box front wall plate, the gas spring support device also includes a support and a base, the base is fixed to the front inner side of the static box side wall plate, the support is fixed to the middle outer side of the dynamic box side wall plate, the upper end of the long gas spring is connected to the base, and the lower end is connected to the support, the two ends of the long gas spring are respectively connected to the storage box through the support and the base, which can ensure the stability of the long gas spring during operation.

[0007] Furthermore: the length of the short gas spring a is greater than or equal to the length of the short gas spring b.

[0008] Furthermore: the upper corners of the three adjacent panels on the top outside of the static box are equipped with reinforced corner pieces, which can effectively resist the force from the items inside the storage box, external vibration or impact, prevent the storage box from deformation or damage, and further enhance the structural strength and durability of the aircraft storage box.

[0009] Furthermore: the front wall panel of the static box and the front wall panel of the dynamic box are equipped with matching locking devices to prevent the storage box from being accidentally opened during the flight of the aircraft.

[0010] Further: the two ends of the long gas spring are connected to the base and the support through hinges, the two ends of the short gas spring a are connected to the reinforced base a and the reinforced support through hinges, and the two ends of the short gas spring b are connected to the reinforced base b and the reinforced support through hinges. The hinge connection allows the gas spring to have a certain degree of rotational freedom during stretching or contraction.

[0011] Beneficial effects: The advantages of the present invention are: through the cooperation of two groups of gas spring support devices, a stable support is provided for the storage box. The layout position of the two short gas springs makes the short gas spring have a different movement state from the long gas spring when the storage box is opened and closed, and the movement speed of the gas spring is relatively slow, which can achieve a buffering effect, which makes it easier to control when operating the storage box. Whether it is opening or closing, it can maintain smooth operation. The matching locking devices on the dynamic box and the static box further improve the safety performance of the storage box.

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0017] An aircraft storage box with a gas spring support device, as shown in the attached Figures 1-2 As shown, the static box 1, the moving box 2, and the gas spring support device 3 are included. The static box 1 is composed of five panels, including two static box side walls 101, a static box front wall 102, a static box top cover 103, and a static box rear wall 105. The moving box 2 is composed of five panels, including two moving box side walls 201, a moving box front wall 202, a moving box bottom wall, and a moving box rear wall. The static box 1 is above the moving box 2, and the open surfaces of the two are facing each other. The static box 1 covers the outside of the moving box 2. The moving box 2 opens and closes relative to the static box 1, and the two are connected at the rear to form a relative flip, with the opening facing the front side of the storage box.

[0018] The four corners of the outer side of the static box top cover 103 are equipped with bracket assemblies 106, which are connected to the wall of the aircraft cabin through a set of matching screws and nuts. The nuts are installed on the cabin ceiling or side wall through reserved holes. The screws are passed through the bracket assembly 106 and then extended into the nuts for connection, thereby realizing the installation of the storage box on the top or side of the cabin.

[0019] The outer corner parts of the three adjacent panels, namely the side wall panel 101, the front wall panel 102 and the top cover panel 103 of the static box, and the outer corner parts of the three adjacent panels, namely the side wall panel 101, the top cover panel 103 and the rear wall panel 105 of the static box, are all equipped with reinforced corner pieces 104 to fasten and cover the corner parts, which can effectively resist the force from the items inside the storage box, external vibration or impact, prevent the storage box from deformation or damage, and further enhance the structural strength and durability of the aircraft storage box.

[0020] The gas spring support device 3 is arranged in one group on each of the left and right sides of the storage box. The gas spring support device 3 specifically includes a long gas spring 31, a short gas spring a32, a short gas spring b33, a reinforced support 34, a reinforced base a35, a reinforced base b36, a support 37, and a base 38.

[0021] The support 37 is fixed to the middle part of the outer side of the dynamic box side wall panel 201, and a hinge is installed on the support 37. The base 38 is fixed to the front part of the inner side of the static box side wall panel 101, and a hinge is installed on the base 38. The upper end of the long gas spring 31 is connected to the base 38 through a hinge, and the lower end is connected to the support 37 through a hinge. The long gas spring 31 is installed at the front of the storage box. The hinge allows the long gas spring 31 to have a certain degree of rotation freedom during stretching or contraction, ensuring smooth movement.

[0022] The reinforcing support 34 is fixed to the inner rear part of the dynamic box side wall plate 201, and a hinge is installed on the reinforcing support 34. The reinforcing base a35 and the reinforcing base b36 are fixed to the inner rear part of the static box side wall plate 101. The reinforcing base a35 and the reinforcing base b36 are arranged up and down in front of the reinforcing support 34, and the reinforcing base a35 and the reinforcing base b36 are both equipped with hinges. The front end of the short gas spring a32 is connected to the reinforcing base a35 through a hinge, and the rear end is connected to the reinforcing support 34 through a hinge. The front end of the short gas spring b33 is connected to the reinforcing base a35 through a hinge. The end is connected to the reinforced base b36 by a hinge, and the rear end is connected to the reinforced support 34 by a hinge. The short gas spring b33 is located below the short gas spring a32, so the short gas spring a32 and the short gas spring b33 are installed at the rear of the storage box. The short gas spring a32 forms an initial downward angle with the horizontal line of the storage box. The minimum initial angle is 0° and the maximum is 30°. The short gas spring a32 and the short gas spring b33 form an angle at the rear end, and the maximum angle is 30°. The maximum opening angle of the storage box is 45°.

[0023] When the storage box is in a closed state, there is a gap between the static box side wall plate 101 and the dynamic box side wall plate 201. The long gas spring 31 is between the static box side wall plate 101 and the dynamic box side wall plate 201, and does not occupy the storage space inside the storage box. The short gas spring a32 is above the static box side wall plate 101, and the short gas spring b33 is also between the static box side wall plate 101 and the dynamic box side wall plate 201, and also does not occupy the storage space inside the storage box.

[0024] Combined with attachment Figure 2 As shown, the horizontal line 4 of the storage box when it is closed is used as the reference. Figure 3 For example, the short gas spring a32 forms an initial downward angle of 0° with the horizontal line 4, and the angle formed between the short gas spring a32 and the short gas spring b33 at the rear end is 30°. The red line is the length of each gas spring when the storage box is closed. When the storage box is opened, the dynamic box 2 rotates relative to the static box 1 and opens at an angle of 45°. The green line is the length of each gas spring when the storage box is opened. It can be seen that the long gas spring 31 changes from a contracted state to a stretched state, that is, the length of the green line is greater than the length of the red line, and the short gas spring a32 and the short gas spring b33 change from a stretched state to a contracted state, that is, the length of the green line is less than the length of the red line.

[0025] When the dynamic box is closed relative to the static box, the long gas spring 31 changes from a stretched state to a contracted state, and the short gas spring a32 and the short gas spring b33 change from a contracted state to a stretched state.

[0026] By the attached Figure 4 For example, the short gas spring a32 forms an initial downward angle of 30° with the horizontal line 4, and the angle formed between the short gas spring a32 and the short gas spring b33 at the rear end is 30°. The red line is the length of each gas spring when the storage box is closed. When the storage box is opened, the dynamic box 2 rotates relative to the static box 1 and opens at an angle of 45°. The green line is the length of each gas spring when the storage box is opened. It can be seen that the long gas spring 31 changes from a contracted state to a stretched state, that is, the length of the green line is greater than the length of the red line, and the short gas spring a32 and the short gas spring b33 change from a stretched state to a contracted state, that is, the length of the green line is less than the length of the red line.

[0027] When the dynamic box is closed relative to the static box, the long gas spring 31 changes from a stretched state to a contracted state, and the short gas spring a32 and the short gas spring b33 change from a contracted state to a stretched state.

[0028] Combined with attachment Figure 1 As shown, if a life raft is installed inside the storage box, when the moving box 2 rotates relative to the static box 1 and opens, the life raft originally in the storage box will fall onto the moving box 2 as the moving box 2 opens, and the life raft can be directly taken out to deal with emergencies. Matching locking devices are installed on the front wall panels 102 of the static box and 202 of the moving box, and the locking is reliable. Even if it is subjected to vibration or impact, it will not cause the storage box to be accidentally unlocked, thereby further improving the safety performance.

[0029] The aircraft storage box with a gas spring support device of the present application provides a stable support for the storage box through the cooperation of two groups of gas spring support devices. The layout position of the two short gas springs makes the short gas spring have a different movement state from the long gas spring when the storage box is opened and closed. When the storage box is opened, the long gas spring stretches and the two short gas springs contract, ensuring that the dynamic box does not rebound and is always in the open state. When the storage box is closed, the long gas spring contracts and the two short gas springs stretch. If heavy objects such as life rafts are stored in the storage box, then a certain force is used to push the dynamic box to the closed state, and the external force is released. Under the action of the gas springs, the dynamic box closes and does not fall, and the closure is more secure and safe. If there is no heavy object in the storage box, push the dynamic box to a certain angle, and under the action of the gas springs, the dynamic box automatically rebounds to the closed state, which is more labor-saving and practical. Such coordination reduces the space occupied by the storage box, improves the tightness and sealing of the dynamic box and the static box when closing, and at the same time enhances the stability of the overall structure. The movement speed of the gas spring is relatively slow, which can achieve a buffering effect, helping the storage box to reach the locked position more easily during the closing process, which makes it easier to control when operating the storage box, and can maintain smooth operation whether it is opening or closing. The matching locking devices on the dynamic box and the static box further improve the safety performance of the storage box.
