Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hydrogen storage devices, and in particular to a hydrogen storage bottle. At the same time, the utility model also relates to a vehicle equipped with the hydrogen storage bottle. Background Art
[0002] With the continuous popularization of clean energy and the continuous development of hydrogen energy technology, hydrogen storage bottles, as key equipment for hydrogen storage and transportation, affect the safety of hydrogen use. Therefore, the performance and quality of hydrogen storage bottles are becoming increasingly important.
[0003] Current hydrogen storage cylinders primarily include the following types: pure steel cylinders (Type I), steel-lined fiber-wound cylinders (Type II), aluminum-lined fiber-wound cylinders (Type III), and plastic-lined fiber-wound cylinders (Type IV). Type I cylinders are gradually being phased out due to their low hydrogen storage density, heavy weight, and poor safety. Type II cylinders have seen improvements in materials and processes, but still have limitations. Compared to Type III cylinders, Type IV cylinders offer advantages such as lighter weight, higher hydrogen storage capacity, longer lifespan, and lower cost.
[0004] However, the existing Type IV high-pressure hydrogen storage cylinders primarily consist of a polymer liner wrapped around a carbon fiber composite material layer. While Type IV cylinders are widely used in small vehicles, high hydrogen storage pressures can lead to leakage from the liner during use. This can cause high pressure between the polymer liner and the carbon fiber composite layer, leading to buckling and deformation of the liner, which in turn compromises vehicle safety. Utility Model Content
[0005] In view of this, the present invention aims to provide a hydrogen storage bottle to improve the safety of vehicles.
[0006] In order to achieve the above-mentioned purpose, the technical solution of the utility model is achieved as follows:
[0007] A hydrogen storage bottle includes a bottle liner and a liner support; the bottle liner includes a first liner and a second liner, the first liner and the second liner are connected together, and the liner support can be fixed in the liner cavity formed by the first liner and the second liner.
[0008] Furthermore, the plane where the connection portion between the first inner liner and the second inner liner is located is orthogonal to the axial arrangement of the hydrogen storage bottle.
[0009] Furthermore, a through hole is provided in the inner liner support, the length direction of the inner liner support and the through hole extends along the axial direction of the hydrogen storage bottle, and the two ends of the inner liner support are respectively abutted against the first inner liner and the second inner liner.
[0010] Furthermore, a rotation-stopping unit is provided between the bottle inner liner and the inner liner support, and the rotation-stopping unit is used to prevent the inner liner support from rotating relative to the bottle inner liner around the axial direction of the bottle inner liner.
[0011] Furthermore, the anti-rotation units are in multiple groups, and the multiple groups of anti-rotation units are arranged at intervals around the circumference of the inner liner of the bottle body.
[0012] Furthermore, the anti-rotation unit includes an anti-rotation protrusion provided on the inner liner of the bottle body, and an anti-rotation groove provided on the inner liner support, and at least a part of the anti-rotation protrusion is embedded in the anti-rotation groove.
[0013] Furthermore, each of the anti-rotation protrusions is in the shape of an elongated strip and extends along the axial direction of the hydrogen storage bottle along the inner wall of the inner liner of the bottle body.
[0014] Furthermore, the inner liner support is provided with a weight-reducing hole.
[0015] Furthermore, both ends of the hydrogen storage bottle along its own axis are provided with openings communicating with the inner tank cavity, and a valve seat is installed at each opening;
[0016] The outer body of the hydrogen storage bottle is sequentially covered with a pressure-resistant layer and a protective layer.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] The hydrogen storage bottle described in the present invention, by limiting the bottle body to consist of a first inner liner and a second inner liner, facilitates the installation and fixation of the inner liner support member, and the inner liner support member can be firmly fixed in the inner liner cavity formed by them. The setting of the inner liner support member can provide additional support for the bottle body inside the bottle body. Through limited weight gain, the shape of the bottle body can be better fixed, thereby enhancing the structural strength of the hydrogen storage bottle, better ensuring that the hydrogen storage bottle maintains a stable shape during use, and preventing the bottle body from buckling or sinking inward when subjected to pressure or impact, thereby helping to improve the safety of the vehicle.
[0019] Secondly, limiting the plane where the connection between the first liner and the second liner is located to be orthogonal to the axial arrangement of the hydrogen storage bottle can increase the stability of the hydrogen storage bottle in the axial direction. When the hydrogen storage bottle is subjected to axial pressure or tension, the connection can better withstand these forces, reducing the relative displacement and deformation between the bottle body and the liner. It is also convenient for manufacturing and assembly, and it is easy to ensure the firmness and sealing of the connection between the two.
[0020] The length of the liner support member and the through-hole extends along the axial direction of the hydrogen storage bottle, so that the liner support member forms a stable support structure inside the liner of the hydrogen storage bottle, providing reliable support for the liner of the hydrogen storage bottle. At the same time, the provision of the through-hole allows the liner support member to be sleeve-shaped, making the liner support member lightweight while providing strong support for the liner. The two ends of the liner support member respectively abut against the first liner and the second liner, which further enhances the stability of the liner.
[0021] Furthermore, a rotation-stop unit is provided between the inner liner and the inner liner support to prevent the inner liner support from rotating relative to the inner liner about the axis of the inner liner. The presence of the rotation-stop unit prevents the inner liner support from shaking, thereby ensuring a more precise and stable position of the inner liner support within the inner liner, thereby facilitating the inner liner support's reinforcing effect on the inner liner. Providing multiple groups of rotation-stop units and defining the arrangement of the multiple groups of rotation-stop units can further enhance the inner liner support's ability to restrict the rotation of the inner liner, and can also make the hydrogen storage bottle more stable, enabling it to better adapt to various complex usage environments and working conditions.
[0022] In addition, the anti-rotation unit includes a anti-rotation protrusion provided on the bottle body and a anti-rotation groove provided on the inner liner support. The anti-rotation protrusion protrudes from the surface of the bottle body, and its shape and size can be precisely calculated to ensure a perfect fit with the anti-rotation groove. The anti-rotation groove is easy to process on the inner liner support and can provide a suitable accommodation space for the anti-rotation protrusion. The anti-rotation protrusion and the anti-rotation groove are snap-fitted, and processing and assembly are relatively convenient. This connection can not only effectively prevent the inner liner support from rotating relative to the bottle body around the axial direction of the bottle body, but also further enhance the overall stability between the bottle body and the inner liner support.
[0023] By designing the anti-rotation protrusion into an elongated shape and extending along the inner wall of the hydrogen storage bottle's liner along its axis, the anti-rotation protrusion acts as a reinforcing rib, thereby strengthening the liner in the axial direction of the hydrogen storage bottle. This effectively increases the structural strength of the liner itself, thereby improving the performance of the hydrogen storage bottle. The elongated anti-rotation protrusion cooperates with the liner support to enhance the liner's anti-buckling ability.
[0024] The provision of weight-reducing holes in the liner support can better meet lightweighting requirements, strengthening the liner structure within the bottle while minimizing weight gain, making the liner support even lighter while meeting strength requirements. Valve seats are provided at both ends of the hydrogen storage bottle, making it suitable for storing gases such as hydrogen and facilitating control of the flow of hydrogen in and out. The pressure-resistant layer prevents the hydrogen storage bottle from rupturing or deforming when internal pressure rises, while the protective layer helps protect the hydrogen storage bottle from scratches, impacts, or other forms of physical damage.
[0025] Another object of the present invention is to provide a vehicle provided with the hydrogen storage bottle as described above.

Those skilled in the art will understand the specific meanings of these terms in this utility model based on specific circumstances.
[0040] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.
[0041] Example 1
[0042] This embodiment relates to a hydrogen storage bottle, which can prevent the inner tank from buckling and deforming, thereby improving the safety of the vehicle. Figures 1 to 4 As shown in FIG, the hydrogen storage bottle of this embodiment includes a bottle body liner 1 and a liner support 2.
[0043] The bottle liner 1 includes a first liner 11 and a second liner 12 , which are connected together and can fix the liner support 2 in the liner cavity 13 formed by the first liner 11 and the second liner 12 .
[0044] The hydrogen storage bottle 4 described in the present invention facilitates the installation and fixation of the liner support 2 by limiting the inner liner 1 of the bottle body to consist of a first liner 11 and a second liner 12, and the liner support 2 can be firmly fixed in the liner cavity 13 formed by them.
[0045] At the same time, through the provision of the inner liner support 2, additional support can be provided for the bottle liner 1 inside the bottle liner 1. Through limited weight gain, the shape of the bottle liner 1 can be better fixed, thereby enhancing the structural strength of the hydrogen storage bottle 4, ensuring that the hydrogen storage bottle 4 maintains a stable shape during use, and preventing the bottle liner 1 from buckling or sinking inward when subjected to pressure or impact, thereby helping to improve the safety of the vehicle.
[0046] It should be noted that the bottle liner 1 and the liner support 2 in this embodiment can be made of plastic materials, such as nylon 6 (PA6), high-density polyethylene (HDPE), and PET polyester plastic. In addition, the liner buckling in this embodiment refers to the large-scale separation and deformation of the liner and the carbon fiber composite material and the intermediate layer.
[0047] Based on the above overall introduction, in this embodiment, as a preferred implementation form, as Figure 3As shown, the plane where the first inner liner 11 and the second inner liner 12 are connected is perpendicular to the axial arrangement of the hydrogen storage bottle 4. By limiting the plane where the first inner liner 11 and the second inner liner 12 are connected to the axial arrangement of the hydrogen storage bottle 4 to be perpendicular, the stability of the hydrogen storage bottle 4 in the axial direction can be increased. When the hydrogen storage bottle 4 is subjected to axial pressure or tension, the connection can better withstand these forces, reducing the relative displacement and deformation between the bottle body and the second inner liner 1. This also facilitates manufacturing and assembly, and ensures the firmness and sealing of the connection between the two.
[0048] It should be understood that in other embodiments, the plane where the connection between the first inner liner 11 and the second inner liner 12 is located may not be orthogonal to the axial direction of the hydrogen storage bottle 4. For example, the plane where the connection between the first inner liner 11 and the second inner liner 12 is located may also be arranged parallel to the axial direction of the hydrogen storage bottle 4, or an acute angle may be set between the plane where the connection between the first inner liner 11 and the second inner liner 12 is located and the axial direction of the hydrogen storage bottle 4.
[0049] And, as a preferred embodiment, Figure 3 As shown, a through hole 22 is provided in the inner liner support 2 of this embodiment. The length directions of the inner liner support 2 and the through hole 22 extend along the axial direction of the hydrogen storage bottle 4, and the two ends of the inner liner support 2 are respectively abutted against the first inner liner 11 and the second inner liner 12.
[0050] The length of the liner support member 2 and through-hole 22 extends axially along the hydrogen storage bottle 4. This arrangement provides a stable support structure for the liner 1 within the hydrogen storage bottle 4, providing reliable support for the liner 1. Furthermore, the provision of through-hole 22 allows the liner support member 2 to assume a sleeve-like shape, making it lightweight while providing strong support for the liner 1. Having both ends of the liner support member 2 abut against the first liner 11 and the second liner 12, respectively, further enhances the stability of the liner 1.
[0051] Furthermore, considering the requirement of stable placement of the liner support 2, in this embodiment, as a preferred embodiment, Figure 1 and Figure 2 As shown in FIG, a rotation-stopping unit 3 is provided between the bottle liner 1 and the liner support 2 , and the rotation-stopping unit 3 is used to prevent the liner support 2 from rotating relative to the bottle liner 1 around the axial direction of the bottle liner 1 .
[0052] Here, a rotation-stop unit 3 is provided between the bottle liner 1 and the liner support 2, which can be used to prevent the liner support 2 from rotating relative to the bottle liner 1 around the axial direction of the bottle liner 1. The presence of the rotation-stop unit 3 can prevent the liner support 2 from shaking, thereby ensuring that the position of the liner support 2 in the bottle liner 1 is more precise and stable, and further conducive to ensuring the reinforcing effect of the liner support 2 on the bottle liner 1.
[0053] Furthermore, in this embodiment, as a preferred implementation form, Figure 3 As shown, multiple groups of anti-rotation units 3 are arranged at intervals around the circumference of the inner liner 1. Here, providing multiple groups of anti-rotation units 3 and defining the arrangement of the multiple groups of anti-rotation units 3 can further enhance the effect of the inner liner support 2 on restricting the rotation of the inner liner 1, and can also make the structure of the hydrogen storage bottle 4 more stable, so that it can better adapt to various complex usage environments and working conditions.
[0054] In specific implementation, the anti-rotation units 3 in this embodiment can be set to four. Of course, in addition to being set to four, corresponding designs and adjustments can also be made according to actual needs, for example, they can be set to five or six.
[0055] Specifically, in this embodiment, as a preferred implementation form, Figure 3 and Figure 4 As shown in the figure, the anti-rotation unit 3 includes an anti-rotation protrusion 31 provided on the inner liner 1 of the bottle body, and an anti-rotation groove 32 provided on the inner liner support 2, and at least part of the anti-rotation protrusion 31 is embedded in the anti-rotation groove 32.
[0056] It can be understood that the anti-rotation unit 3 includes a anti-rotation protrusion 31 provided on the inner liner, and a anti-rotation groove 32 provided on the inner liner support 2. The anti-rotation protrusion 31 protrudes from the surface of the inner liner, and its shape and size can be precisely calculated to ensure a perfect fit with the anti-rotation groove 32. The anti-rotation groove 32 is easy to process on the inner liner support 2, and can provide a suitable accommodation space for the anti-rotation protrusion 31. The anti-rotation protrusion 31 and the anti-rotation groove 32 are snap-fitted, and are relatively convenient to process and assemble. This connection can not only effectively prevent the inner liner support 2 from rotating relative to the inner liner around the axis of the inner liner, but also further enhance the overall stability between the inner liner and the inner liner support 2.
[0057] In the specific structure, the inner wall of the inner liner 1 is provided with four anti-rotation protrusions 31 spaced along its circumferential direction. Meanwhile, the outer wall of the inner liner support 2 is provided with anti-rotation grooves 32 at locations contacting the anti-rotation protrusions 31. Each anti-rotation groove 32 is elongated and extends axially along the inner liner support 2, passing through both ends of the inner liner support 2. Of course, in addition to being elongated, the anti-rotation grooves 32 can also be provided in other common shapes, as long as they can ensure that the anti-rotation protrusions 31 are stably engaged in the anti-rotation grooves 32.
[0058] At the same time, in this embodiment, as a preferred implementation form, Figure 2 and Figure 3 As shown in , each anti-rotation protrusion 31 is elongated and extends axially along the inner wall of the liner 1 of the hydrogen storage bottle 4. Here, the anti-rotation protrusions 31 are configured as elongated strips and extend axially along the inner wall of the liner along the hydrogen storage bottle 4. These anti-rotation protrusions 31 act as reinforcing ribs, thereby strengthening the liner 1 axially of the hydrogen storage bottle 4. This effectively increases the structural strength of the liner 1, thereby improving the performance of the hydrogen storage bottle 4. The elongated anti-rotation protrusions 31 cooperate with the liner support member 2 to enhance the liner's anti-buckling capability.
[0059] In a specific implementation, in the radial direction of the inner liner 1 of the bottle body, one end of each anti-rotation protrusion 31 is clamped in the corresponding anti-rotation groove 32 to prevent the inner liner support 2 from rotating.
[0060] In addition, in this embodiment, as a preferred implementation form, Figure 3 As shown, the liner support 2 is provided with a weight-reducing hole 21. This arrangement can better meet the lightweight requirements, while increasing the weight less to achieve the reinforcement of the bottle liner 1 structure, making the liner support 2 lighter while meeting the strength requirements.
[0061] In the specific structure, the inner liner support 2 is provided with four groups of weight-reducing holes 21 arranged along its own circumferential spacing, that is, a weight-reducing hole group is provided between two adjacent stop grooves 32, and each weight-reducing hole group includes four weight-reducing holes 21 arranged along the axial spacing of the inner liner support 2, and each weight-reducing hole 21 can be set to be a long strip extending along the axial direction of the inner liner support 2.
[0062] In this way, the support strength of the liner 1 in the bottle body can be guaranteed while reducing weight. Moreover, the provision of the weight-reducing hole 21 can also allow hydrogen to enter the liner support member 2, thereby reducing the impact on the hydrogen storage volume. Of course, in addition to being configured as a long strip, the weight-reducing hole 21 can also be configured as other common shapes.
[0063] It should be understood that the number of weight-reducing hole groups can be designed and adjusted accordingly based on actual weight reduction requirements, for example, eight can be provided (i.e., two weight-reducing hole groups 21 are provided between two adjacent anti-rotation grooves 32). Furthermore, the number of weight-reducing holes 21 in each weight-reducing hole group can also be designed and adjusted accordingly based on actual requirements, for example, five or six can be provided.
[0064] In addition, in this embodiment, as a preferred implementation form, Figure 1As shown, both ends of the hydrogen storage bottle 4 along its own axis are provided with openings connected to the inner tank cavity 13, and a valve seat 43 is installed at each opening. In addition, the barrel 41 of the hydrogen storage bottle 4 is sequentially covered with a pressure-resistant layer and a protective layer.
[0065] Therefore, valve seats 43 are set at both ends of the hydrogen storage bottle 4, so that the hydrogen storage bottle 4 is suitable for storing gases such as hydrogen and is convenient for controlling the inflow and outflow of hydrogen. The pressure-resistant layer can prevent the hydrogen storage bottle 4 from rupturing or deforming when the internal pressure increases, and the protective layer can help prevent the hydrogen storage bottle 4 from being scratched, impacted or subjected to other forms of physical damage.
[0066] Specifically, the hydrogen storage bottle 4 of this embodiment comprises a barrel 41 and end caps 42 located at both ends of the barrel 41. The barrel 41 is disposed in the middle of the hydrogen storage bottle 4 along the axial direction of the hydrogen storage bottle 4, and the barrel 41 has a cylindrical shape. It is worth mentioning that the pressure-resistant layer in this embodiment can be made of a carbon fiber reinforced composite material, such as CFRP (Carbon Fiber Reinforced Plastic) or CFRP (Carbon Fiber Reinforced Polymer). Specifically, the pressure-resistant layer can be made of carbon fiber and epoxy resin.
[0067] The protective layer in this embodiment can be made of a glass fiber reinforced composite material, such as GFRP (Glass Fiber Reinforced Plastic) or GFRP (Glass Fiber Reinforced Polymer). Specifically, it can be composed of glass fiber and epoxy resin. The specific preparation methods of the pressure-resistant layer and protective layer in this embodiment can be referred to in the prior art and will not be further described here.
[0068] Furthermore, it is understood that dividing the bottle liner 1 into the first liner 11 and the second liner 12 facilitates the installation of the valve seat 43. In specific implementations, the valve seat 43 can be bonded to the opening at the end of the bottle liner 1. Of course, in addition to bonding, other common connection methods can also be used. Furthermore, the structure of the valve seat 43 in this embodiment can refer to existing structures.
[0069] The hydrogen storage bottle 4 of this embodiment is suitable for use as a hydrogen storage device. During use, the bottle liner 1 is injection molded into two symmetrical parts, such as the first liner 11 and the second liner 12. After the liner support member 2 is fixed to the anti-rotation protrusion 31 via the anti-rotation groove 32 thereon, the first liner 11 and the second liner 12 can be connected together through a welding process, thereby achieving internal reinforcement and sealing of the bottle liner 1, which can effectively prevent the liner from buckling. Of course, in addition to welding, other common connection methods can also be used between the first liner 11 and the second liner 12, as long as they can ensure the structural strength of the hydrogen storage bottle 4.
[0070] Example 2
[0071] This embodiment relates to a vehicle, which is provided with the hydrogen storage bottle 4 in the first embodiment.
[0072] The vehicle in this embodiment adopts the hydrogen storage bottle 4 in Example 1, which can provide additional support for the inner liner 1 of the bottle body through the inner liner support 2, and can better fix the shape of the inner liner 1 of the bottle body, thereby preventing the inner liner 1 of the bottle body from buckling or sinking inward when subjected to pressure or impact, thereby improving the safety of the vehicle.
[0073] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
