In an exemplary embodiment of the present invention, a vehicle mounted pressure vessel apparatus is provided, as shown in fig. 1-4.
The vehicle-mounted pressure vessel apparatus shown in fig. 1 is used for storing gas or liquid, such as hydrogen, liquefied hydrogen, natural gas, liquefied natural gas, etc., and both gas and liquid may exist inside the vehicle-mounted pressure vessel. The high-pressure hydrogen storage device is particularly applied to a high-pressure hydrogen storage scene and mainly comprises a storage cabin 5 and a reinforcing shell 3, the axis of the storage cabin 5 is butted end to form a closed annular structure, the axial stress of the storage cabin 5 is offset, the deformation of the storage cabin 5 in the radial direction and the circumferential direction can be restrained by the reinforcing shell 3 formed by the outer wall of the storage cabin 5 and a winding reinforcing structure, and the storage capacity and the safety of the storage cabin 5 can be guaranteed by well protecting the storage cabin 5.
As shown in fig. 1 and 4, the vehicle-mounted pressure vessel device comprises a storage compartment 5 and a reinforcing shell 3 wrapped outside the storage compartment 5, wherein the reinforcing shell 3 is attached to the outer wall of the storage compartment 5 and exerts constraint force on the storage compartment 5 in the circumferential direction and the radial direction. Meanwhile, the reinforcing shell 3 is arranged coaxially with the storage compartment 5, covering the outer wall of the storage compartment 5.

For the structure of the storage cabin 5, the axis of the cavity 4 is a closed curve connected end to end, the cavity 4 and the storage cabin 5 are coaxially distributed, the axis of the storage cabin 5 is circular, and the axis of the cavity 4 is circular and coincides with the axis of the storage cabin 5.
It will be appreciated that the axis of the storage compartment 5 may also be other smooth planar or spatial curvilinear shapes such that the axis of the storage compartment 5 is a closed curve, while at the same time, the storage compartment 5 is formed internally with a closed cavity 4 that is continuous along the axis.
In addition, the chamber 4 and the storage chamber 5 are coaxially distributed, so that the bulkheads of the storage chamber 5 can be uniformly distributed, and the thicknesses of the bulkheads on one side of the storage chamber 5 corresponding to the inner ring of the annular structure and one side close to the outer ring of the annular structure can be arranged according to requirements so as to meet the requirements of constraint force at different positions.
As shown in fig. 1, the storage compartment 5 is circular in cross section perpendicular to its axis and forms a circular ring-shaped structure with a circular axis.
As shown in fig. 2, the storage compartment 5 has an oval cross-section perpendicular to its axis and forms a circular ring-shaped structure with a circular axis; as shown in fig. 3, the storage compartment 5 is oblong in cross section perpendicular to its axis and forms a circular ring-shaped structure with a circular axis.
In other embodiments, the cross section of the storage compartment 5 along the axis perpendicular thereto may also be in other shapes, such as a rounded rectangle, a rounded pentagon, etc., and the shape of the storage compartment 5 is selected according to the processing difficulty and the installation position requirement, so that the storage compartment can meet the requirements of capacity, safety and volume.
In this embodiment, strengthen the shell 3 and be provided with the enhancement shell outward, strengthen the shell including being used for holding the chamber that holds that strengthens shell 3, storage compartment 5, strengthen the shell and be rigid structure, including last casing and lower casing, go up the casing and be equipped with the recess respectively with lower casing, when going up casing butt joint lower casing, the recess intercommunication forms jointly and holds the chamber. The strengthening shell is fixed on the vehicle and used for protecting the strengthening shell 3 and the storage cabin 5 through a rigid structure, and the problems of leakage and explosion caused by the fact that the strengthening shell 3 and the storage cabin 5 are pierced by an external structure when the vehicle is collided are avoided.
Example 2
In another exemplary embodiment of the present invention, as illustrated in fig. 1-4, an on-board pressure vessel arrangement is provided.
The difference from embodiment 1 is that the vehicle-mounted pressure vessel device in this embodiment is not provided with the reinforcement case 3, and other technical features are the same as those in embodiment 1.
On-vehicle pressure vessel device in this embodiment is including storing cabin 5, stores 5 inside cavitys 4 that are equipped with along storing 5 axial distributions in cabin, stores 5 axis end to end butt joints in cabin intercommunication and forms annular structure, and cavity 4 forms closed annular cavity, and annular structure's inner circle forms the arrangement space 2 that is used for holding observing and controling subassembly 1, stores the cabin 5 and is connected with butt joint pipe 7.
The main function of the storage cabin 5 is to contain gas or liquid and form a seal, the storage cabin 5 with an annular structure can improve the strength of the storage cabin 5 to reduce an additional reinforcing structure, and when the reinforcing shell 3 is not arranged, the strength of the storage cabin 5 body is utilized, so that the storage cabin can be applied to medium and low pressure scenes, such as liquefied gas storage.
When the pressure in the annular storage cabin 5 is higher, the reinforcing shell 3 can be wound outside the annular storage cabin to reinforce the annular cavity, so that the capacity of bearing high pressure is achieved.
Under the condition of the same storage volume, the storage cabin 5 adopting the annular structure has smaller volume compared with the existing cylindrical high-pressure gas storage cylinder, so that the overall weight and cost are reduced, and the material is saved.
The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
