Description

Technical Field

[0001] This invention relates to the field of commercial vehicle technology, and in particular to a vehicle-mounted Type IV pressure vessel fixing and alarm device. Background Technology

[0002] The most mature pressure vessel for passenger cars and commercial vehicles is the Type III cylinder. However, with technological advancements, the Type IV pressure vessel has been certified and developed. The Type IV pressure vessel uses a plastic inner liner, which has excellent resistance to hydrogen embrittlement and corrosion, high product safety, strong toughness and deformation coordination, and a fatigue life of over 45,000 cycles. Its hydrogen storage density is higher than that of the same-sized Type III cylinder, and the larger the volume and pressure, the more obvious its weight advantage. At a working pressure of 70 MPa, the Type IV pressure vessel has the advantages of being lightweight and low-cost, and can provide hydrogen supply security for various vehicle types, including passenger cars and commercial vehicles.

[0003] However, because the inner liner of a Type IV pressure vessel is not pressurized, the length and diameter of the cylinder change with pressure. During assembly, the surface of the pressure vessel is secured with fastening straps, and then fixed with bolts. This method of fixing the Type IV pressure vessel results in inconsistent tightness depending on fuel pressure, leading to poor reliability. Furthermore, there is no monitoring or alarm warning for the installation status during vehicle operation, resulting in poor safety. Summary of the Invention

[0004] The purpose of this invention is to provide a vehicle-mounted Type IV pressure vessel fixing and alarm device to address the shortcomings of existing technologies.

[0005] This invention is achieved using the following technical solution:

[0006] A vehicle-mounted Type IV pressure vessel fixing and alarm device includes a Type IV pressure vessel, which is fixed to the vehicle frame by a connecting mechanism. The connecting mechanism is equipped with a displacement sensor, and the Type IV pressure vessel contains fuel.

[0007] Preferably, the Type IV pressure vessel is provided with a front mounting shaft and a rear mounting shaft at its front and rear ends, respectively. The front mounting shaft is provided with a front mounting flange, and the rear mounting shaft is provided with a rear mounting flange. The front mounting shaft is fixedly connected to the front mounting flange, and the rear mounting shaft is movably connected to the rear mounting flange. Both the front mounting flange and the rear mounting flange are fixedly connected to the vehicle frame through a connecting mechanism.

[0008] Preferably, the connecting mechanism includes a front connecting plate, a rear connecting plate, a front connecting bracket, and a rear connecting bracket. The front mounting flange is connected to the front connecting bracket via the front connecting plate, and the front connecting bracket is connected to the vehicle frame. The rear mounting flange is connected to the rear connecting bracket via the rear connecting plate, and the rear connecting bracket is connected to the vehicle frame. The rear connecting plate is equipped with the displacement sensor.

[0009] Preferably, the rear connecting plate is provided with a displacement sensor bracket, the displacement sensor is connected to the displacement sensor bracket by a fixing clamp, and the detection end of the displacement sensor is correspondingly set with the rear mounting shaft.

[0010] Preferably, the displacement sensor is connected to the controller, and the controller is connected to the vehicle instrument panel or a cloud server. When the fuel pressure in the Type IV pressure vessel changes, the displacement sensor collects the displacement change of the mounting shaft, inputs the displacement change into the controller, compares it with the calibrated pressure value, determines the installation status of the Type IV pressure vessel, and sends an alarm reminder to the vehicle instrument panel or to the user's mobile phone via the cloud server.

[0011] Compared with the prior art, the present invention has the following beneficial technical effects:

[0012] The connecting mechanism can be pre-assembled with the Type IV pressure vessel. During assembly, only the connecting bracket needs to be connected to the frame, which improves assembly efficiency. It can be matched with a variety of Type IV pressure vessels of different diameters and lengths, and has high versatility. There are fewer types of parts, and after-sales maintenance is simple.

[0013] Type IV pressure vessels are mounted on the side of the vehicle frame via a connecting mechanism. There are no size restrictions, and the design diameter of Type IV pressure vessels can be increased, thereby improving the utilization of vehicle space. The installation status is monitored in real time, and any abnormalities can be automatically identified and alarms can be triggered. Attached Figure Description

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solutions of this invention, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this invention.

[0020] like Figures 1-4 As shown, a vehicle-mounted type IV pressure vessel fixing and alarm device includes a type IV pressure vessel 10, which is fixed to the vehicle frame 20 by a connecting mechanism. The connecting mechanism is equipped with a displacement sensor 60, and the type IV pressure vessel 10 contains fuel.

[0021] The Type IV pressure vessel 10 is provided with a front mounting shaft and a rear mounting shaft 11 at its front and rear ends, respectively. The front mounting shaft is provided with a front mounting flange 12, and the rear mounting shaft 11 is provided with a rear mounting flange 13. The front mounting shaft is fixedly connected to the front mounting flange 12, and the rear mounting shaft 11 is movably connected to the rear mounting flange 13. Both the front mounting flange 12 and the rear mounting flange 13 are fixedly connected to the frame 20 through a connecting mechanism.

[0022] The connecting mechanism includes a front connecting plate 30, a rear connecting plate 31, a front connecting bracket 40, and a rear connecting bracket 41. The front mounting flange 12 is connected to the front connecting bracket 40 via the front connecting plate 30, and the front connecting bracket 40 is connected to the vehicle frame 20. The rear mounting flange 13 is connected to the rear connecting bracket 41 via the rear connecting plate 31, and the rear connecting bracket 41 is connected to the vehicle frame 20. The rear connecting plate 31 is equipped with a displacement sensor 60.

[0023] The rear connecting plate 31 is provided with a displacement sensor bracket 50. The displacement sensor 60 is connected to the displacement sensor bracket 50 through a fixing clamp 70. The detection end of the displacement sensor 60 is set to correspond to the rear mounting shaft 11.

[0024] The displacement sensor 60 is connected to the controller, which is connected to the vehicle instrument panel or a cloud server. When the fuel pressure in the Type IV pressure vessel 10 changes, the displacement sensor 60 collects the displacement change of the rear mounting shaft 11, inputs the displacement change into the controller, compares it with the calibrated pressure value, determines the installation status of the Type IV pressure vessel 10, and sends an alarm reminder to the vehicle instrument panel or to the user's mobile phone via the cloud server.

[0025] The Type IV pressure vessel 10 undergoes dimensional changes in both diameter and length due to variations in fuel pressure. During manufacturing, the front mounting flange 12 and the rear mounting flange 13 are fixed to both ends of the Type IV pressure vessel 10. The front mounting flange 12 is fixedly connected to the Type IV pressure vessel 10, meaning its position does not change with pressure variations. The rear mounting flange 13 moves axially with pressure variations, and its diameter is not constrained by any fasteners, allowing it to freely change with pressure. This satisfies the characteristics of the Type IV pressure vessel 10.
