Description

Technical Field

[0001] This invention relates to the field of vehicle-mounted hydrogen storage cylinder technology, specifically to a vibration isolation structure for vehicle-mounted hydrogen storage cylinders. Background Technology

[0002] As the name suggests, on-board hydrogen storage cylinders are high-pressure container systems installed on hydrogen fuel cell vehicles or hydrogen internal combustion engine vehicles to store the hydrogen fuel required to supply the fuel cell or engine. It is one of the core components of hydrogen fuel cell vehicles and directly determines the vehicle's range, safety performance and cost. The purpose of the vibration isolation structure is to protect the cylinders from vibration and impact from uneven road surfaces and the vehicle's power system, and to prevent them from premature fatigue failure. Existing vehicle-mounted hydrogen storage cylinder vibration isolation structures mostly rely on bolts for cylinder installation. To ensure installation stability, multiple bolts are needed, requiring simultaneous alignment of multiple bolt holes. Due to manufacturing tolerances and deformation of rubber gaskets, hole alignment often requires repeated adjustments. Operators must use their hands or tools to pry the heavy cylinders or supports, which is very strenuous. After inserting the bolts, they must be tightened according to strict torque and sequence requirements (a cross-tightening sequence must be used to ensure uniform pressure and prevent uneven stress on the cylinder shell). This process is not only time-consuming but also demands high levels of skill and patience from the operator, thus causing inconvenience for staff. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a vibration isolation structure for vehicle-mounted hydrogen storage cylinders. This solves the problem that existing vibration isolation structures for vehicle-mounted hydrogen storage cylinders mostly rely on bolt fixing for cylinder installation. To ensure installation stability, multiple bolts are needed, requiring simultaneous alignment of multiple bolt holes. Due to manufacturing tolerances and deformation of rubber gaskets, hole alignment often requires repeated adjustments. Operators must manually or with tools pry the heavy cylinder or support, which is very strenuous. Furthermore, after inserting the bolts, they must be tightened according to strict torque and sequence requirements (a crisscross tightening sequence is necessary to ensure uniform pressure and prevent uneven stress on the cylinder shell). This process is not only time-consuming but also demands high skill and patience from the operator, thus causing inconvenience for users.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a vibration isolation structure for a vehicle-mounted hydrogen storage cylinder, comprising a horizontal plate, a first mounting hoop fixedly connected to the rear top of the horizontal plate, a second mounting hoop abutting the front top of the horizontal plate, slide rails slidably engaging on both inner walls of the second mounting hoop, and the bottoms of the two slide rails being fixedly connected to the top of the horizontal plate, a screw rotatably connected to the inner wall of the second mounting hoop via a sealed bearing, and a vertical plate fixedly connected to the inner wall of the screw via a threaded connection.

[0005] Preferably, limit blocks are fixedly connected to the top front and rear sides of the two slide rails, and fastening nuts are pressed against the front and rear sides of the outer wall of the vertical plate, and the inner walls of the two fastening nuts are threadedly connected to the outer wall of the screw.

[0006] Preferably, the inner walls of both the first mounting hoop and the second mounting hoop are fixedly connected with a first rubber pad, and the inner walls of both the first mounting hoop and the second mounting hoop are machined with openings.

[0007] Preferably, vibration isolation blocks are fixedly connected to both sides of the bottom of the horizontal plate, and mounting plates are fixedly connected to the bottom of both vibration isolation blocks.

[0008] Preferably, a second rubber pad is fixedly connected to the bottom of each of the two mounting plates, and mounting holes are machined on the inner walls of both mounting plates and the two second rubber pads.

[0009] Beneficial effects This invention provides a vibration isolation structure for vehicle-mounted hydrogen storage cylinders. It offers the following advantages: This vibration isolation structure, through the cooperation of a horizontal plate, a first mounting clamp, a slide rail, a second mounting clamp, a screw, a vertical plate, and a fastening nut, allows for the fixing of the cylinder body by adjusting the position between the second and first mounting clamps using the screw. This eliminates the need for excessive bolts, significantly reducing installation difficulty and improving overall work efficiency.

[0012] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0013] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0014] Existing vehicle-mounted hydrogen storage cylinder vibration isolation structures mostly rely on bolts for cylinder installation. To ensure installation stability, multiple bolts are needed, requiring simultaneous alignment of multiple bolt holes. Due to manufacturing tolerances and deformation of rubber gaskets, hole alignment often requires repeated adjustments. Operators must use their hands or tools to pry the heavy cylinders or supports, which is very strenuous. After inserting the bolts, they must be tightened according to strict torque and sequence requirements (a cross-tightening sequence must be used to ensure uniform pressure and prevent uneven stress on the cylinder shell). This process is not only time-consuming but also demands high skill and patience from the operator, thus causing inconvenience for staff. In view of this, the present invention provides a vibration isolation structure for vehicle-mounted hydrogen storage cylinders. Through the cooperation of a horizontal plate, a first mounting clamp, a slide rail, a second mounting clamp, a screw, a vertical plate, and a fastening nut, the cylinder body can be fixed by adjusting the position between the second mounting clamp and the first mounting clamp using the screw, without the need for excessive bolts. This greatly reduces the installation difficulty and improves the overall work efficiency. Furthermore, the fastening nut can tighten and limit the screw, thereby preventing the screw from twisting and loosening, and ensuring the stability of use.

[0015] Example 1: By Figure 1 , 2 As can be seen from 3 and 4, a vibration isolation structure for a vehicle-mounted hydrogen storage cylinder includes a horizontal plate 1. A first mounting hoop 2 is fixedly connected to the rear top of the horizontal plate 1, and a second mounting hoop 4 is attached to the front top of the horizontal plate 1. Slide rails 3 are slidably engaged on both inner walls of the second mounting hoop 4, and the bottom of both slide rails 3 is fixedly connected to the top of the horizontal plate 1. A screw 5 is rotatably connected to the inner wall of the second mounting hoop 4 through a sealed bearing, and a vertical plate 6 fixedly connected to the inner wall of the horizontal plate 1 is threadedly connected to the outer wall of the screw 5. In the specific implementation process, it is worth noting that the slide rail 3 can restrict the position of the second mounting clamp 4, so that the second mounting clamp 4 can only achieve simple forward reciprocating motion, and the twisting screw 5 can change the position of the second mounting clamp 4 on the outer wall of the slide rail 3. Furthermore, limit blocks 10 are fixedly connected to the top front and rear sides of the two slide rails 3, and fastening nuts 12 are pressed against the front and rear sides of the outer wall of the vertical plate 6, and the inner walls of the two fastening nuts 12 are threadedly connected to the outer wall of the screw 5. In the specific implementation process, it is worth noting that a nylon ring (nylon self-locking nut) can be embedded in the inner wall of the two fastening nuts 12, or the entire threaded hole can be lined with a nylon coating. When tightening, the thread of the screw 5 compresses the nylon, and the nylon undergoes elastic or plastic deformation, thereby generating huge normal pressure and friction to increase the friction between the fastening nuts 12 and the screw 5. In turn, the two fastening nuts 12 abut against each other to lock and limit the screw 5. The limiting block 10 can prevent the second mounting clamp 4 from dislodging from the outer wall of the slide rail 3. Furthermore, the inner walls of the first mounting clamp 2 and the second mounting clamp 4 are both fixedly connected with the first rubber pad 14, and the inner walls of the first mounting clamp 2 and the second mounting clamp 4 are both machined with openings 7; In the specific implementation process, it is worth noting that the first rubber pad 14 can increase the friction between the first mounting clamp 2, the second mounting clamp 4 and the bottle body, so as to improve the connection stability. Furthermore, vibration isolation blocks 8 are fixedly connected to both sides of the bottom of the horizontal plate 1, and mounting plates 9 are fixedly connected to the bottom of the two vibration isolation blocks 8. In the specific implementation process, it is worth noting that the vibration isolation block 8 is an elastomer vibration isolator made of high-performance rubber or polyurethane material. Its essence is a "spring and damping integrated element". When the rubber / polyurethane material is deformed, the internal molecules will generate fierce friction, thereby converting mechanical energy (vibration) into heat energy and dissipating it. This means that they can isolate vibration like a spring and can automatically and quickly attenuate vibration to prevent residual vibration, so as to play the role of vibration isolation. The staff can use the mounting plate 9 to install the vehicle-mounted hydrogen storage cylinder vibration isolation structure onto the vehicle. It is understood that the mounting plate 9 provided in this embodiment is only one possible implementation method for fixing the external vehicle, and not all embodiments. In the specific implementation process, other structures can also be used. The specific structure selection can be reasonably designed according to the actual situation. Furthermore, a second rubber pad 11 is fixedly connected to the bottom of each of the two mounting plates 9, and mounting holes 13 are machined on the inner walls of both mounting plates 9 and the two second rubber pads 11. In the specific implementation process, it is worth noting that the second rubber pad 11 can increase the connection friction between the mounting plate 9 and the external vehicle in order to improve the connection tightness. The staff can use bolts through the mounting hole 13 to realize the installation of the vehicle-mounted hydrogen storage cylinder vibration isolation structure. Specifically, when using this vehicle-mounted hydrogen storage cylinder vibration isolation structure, during cylinder installation, the operator first tightens the fastening nut 12 to adjust its position so as not to affect the rotation of the screw 5. Then, the operator tightens the screw 5, which causes the second mounting clamp 4 to slide along the outer wall of the slide rail 3 to adjust the position between the second mounting clamp 4 and the first mounting clamp 2. When the position is appropriate, the operator places the cylinder inside the first mounting clamp 2 and the second mounting clamp 4. Then, the operator tightens the screw 5 again, which again causes the second mounting clamp 4 to slide along the outer wall of the slide rail 3. At this point, the cylinder can be clamped and fixed by the second mounting clamp 4 and the first mounting clamp 2. Then, the operator uses the fastening nut 12 to lock and limit the screw 5, thus completing the cylinder installation.

[0016] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
