Description

Technical Field

[0001] This utility model relates to the field of onboard natural gas technology for new energy vehicles, and in particular to an onboard natural gas cylinder frame assembly. Background Technology

[0002] The onboard natural gas cylinder frame assembly is a key safety component of natural gas vehicles, primarily used to secure and protect high-pressure gas cylinders, ensuring their stability and safety during vehicle operation, collisions, or extreme environments. While existing technology is relatively mature, the following issues still exist:

[0003] 1) Poor adaptability to dynamic loads: When the existing frame is subjected to vibration and impact under complex road conditions, it is prone to fatigue cracks, and the connecting parts may loosen, leading to displacement or leakage of gas cylinders.

[0004] 2) Insufficient collision protection: The frame structure is not adequately designed to protect against extreme conditions such as side collisions or rollovers, and lacks an energy-absorbing and collapsing mechanism, which may lead to the risk of gas cylinder rupture or explosion.

[0005] Therefore, there is an urgent need to design an on-board natural gas cylinder frame assembly to solve the above-mentioned technical problems. Summary of the Invention

[0006] The purpose of this invention is to provide a vehicle-mounted natural gas cylinder frame assembly that can improve the load-bearing strength of the frame by optimizing the frame structure, thereby improving the stability of the cylinder placement while meeting strength requirements.

[0007] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0008] A vehicle-mounted natural gas cylinder frame assembly includes a frame body with multiple cylinder placement beams arranged sequentially from top to bottom. A control panel mounting bracket is provided on the side of the frame body. A central support vertical beam is provided on both the front and rear sides of the frame body. The assembly is characterized by: multiple placement bases with curvatures consistent with the cylinder shape on the cylinder placement beams; multiple support frames on the bottom surface of the cylinder placement beams; wherein the support frames located at both ends of the bottom of the cylinder placement beams have their vertical sides connected and fixed to the vertical beams of the frame body, and their horizontal sides connected and fixed to the bottom surface of the cylinder placement beams; and the support frame located in the middle of the bottom of the cylinder placement beams has its vertical side fixed to the central support vertical beam of the frame body, and its horizontal side connected and fixed to the bottom surface of the cylinder placement beams.

[0009] Improvement to the above technical solution: The support frame is a triangular support structure, wherein the hypotenuse of the support frame is an arc-shaped side with a curved shape, which matches the curvature of the gas cylinder on the gas cylinder safety beam below.

[0010] Further improvements to the above technical solution: The frame body is provided with a diagonal brace on both the front and rear sides. The upper end of the diagonal brace is fixed to the support vertical beam, and the lower end of the diagonal brace is fixed to the outer edge of the bottom frame of the frame body.

[0011] A further improvement to the above technical solution: the mounting base is provided with a gas cylinder clamp bracket, the gas cylinder clamp bracket is aligned with the curvature of the mounting base, the upper surface of the mounting base is provided with multiple slots, and the bottom surface of the gas cylinder clamp bracket is provided with a fixing block corresponding to the slot.

[0012] A further improvement to the above technical solution: the mounting base is provided with multiple openings, the gas cylinder is placed on the mounting base, and the gas cylinder clamp is adjusted and fixed through the openings on the mounting base.

[0013] Further improvements to the above technical solution: the frame body is provided with two diagonal bracing beams on the upper and lower surfaces respectively, and diagonal bracing beams are provided between the middle supporting vertical beams. Beneficial effects

[0014] Using the vehicle-mounted natural gas cylinder frame assembly described in this utility model, the base is aligned with the cylinder's curvature, improving the cylinder's fit and stability and reducing displacement. The triangular support structure, especially the curved edges, enhances the supporting force and stress dispersion capabilities, thereby improving dynamic load adaptability. The diagonal tie beam increases the overall structural rigidity and impact resistance, especially in absorbing energy during collisions. The slot and fixing block design ensures a more secure cylinder fixation, while the open design allows for adjustment of the clamps to accommodate different cylinder sizes, improving compatibility. This effectively solves the problems of poor dynamic load adaptability and insufficient collision protection in existing cylinder frames, leading to fatigue cracking under complex road conditions, loosening of connecting parts, and cylinder displacement or leakage. Furthermore, insufficient collision protection results in a lack of energy absorption mechanisms during side collisions or rollovers, potentially causing cylinder rupture or explosion.
