Description

Technical Field

[0001] The utility model relates to the technical field of automobiles, in particular to a gas supply device for new energy vehicles. Background Art

[0002] New energy vehicles refer to vehicles that use unconventional vehicle fuels as the power source and integrate advanced technologies in vehicle power control and drive. They have advanced technical principles, new technologies, and new structures. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc. Hydrogen engine vehicles require a gas supply device to store and provide hydrogen (hydrogen energy) to supply hydrogen sources for fuel cell vehicles. This gas supply device is a type of new energy vehicle technology, especially suitable for fuel cell vehicles. The main function of the new energy vehicle gas supply device is to store high-pressure hydrogen to provide power for the vehicle when needed. The new energy vehicle gas supply device is the most common and direct hydrogen storage method. Hydrogen is transported in the gas supply device under high pressure (15.2 - 70.9 MPa). With the development of materials science, high-pressure gas cylinders made of carbon fiber and aluminum composite materials have been developed, greatly reducing the mass of the gas cylinder itself and improving the capacity loading efficiency. However, for common new energy vehicle gas supply devices on the market, with the continuous jolting of the vehicle, it is easy for the structure fixing the gas supply device to become loose, and after loosening, it requires professional personnel to tighten, which is rather cumbersome. Moreover, during the production, transportation, and use of new energy vehicle gas supply devices, the pressure regulator is extremely easy to be damaged after being collided, posing a safety hazard.

[0023] Embodiment 1: Please refer to Figures 1 to 6 :

[0024] The present utility model provides a gas supply device for a new energy vehicle, including: a device body 1; the side of the device body 1 is connected to a connector component 106 through a connection component 104 and a pulling groove 105. Two connector components 106 are welded and fixed to a support plate component 107 made of elastic metal, enabling the support plate component 107 to freely deform by virtue of elasticity, facilitating the insertion of the connector component 106 into the inside of the pulling groove 105, and at the same time enhancing the protection effect by means of elasticity. The middle position of the U-shaped support plate component 107 is of a circular structure, and a contact component 108 made of flexible rubber is adhesively bonded to the middle position inside the support plate component 107 for contacting the outside of the pressure regulator 103 to improve the protection effect on the pressure regulator 103; a chassis structure 2; the chassis structure 2 is installed at the bottom of the device body 1 for support. Two adjusting structures 204 are inserted through the inside of the chassis structure 2. The outer end of the adjusting structure 204 is of a hexagonal structure, facilitating the use of a wrench to control the rotation of the adjusting structure 204. Two symmetrical threads are provided on the outside of the adjusting structure 204. Each adjusting structure 204 is connected to two pushing heads 205 through the threads. After the adjusting structure 204 rotates, the two pushing heads 205 are controlled to move together through the threads, pulling the fixed belt structure 208 to tighten, improving the fixing effect on the device body 1. The pushing head 205 is connected to the fixed belt structure 208 through a force-bearing plate structure 206 and a force-bearing block 207.

[0025] In the embodiments of the present disclosure, as Figure 3 and Figure 4As shown, there are two positioning grooves 101 in the shape of circular rings on the outside of the device body 1 for embedding the fixing belt structure 208 to improve the positioning connection effect. Inside each positioning groove 101, anti-slip grooves 102 are evenly arranged. The inner side edges of the anti-slip grooves 102 are inclined structures to improve the anti-slip fixing effect with the fixing belt structure 208. At the front end of the device body 1, there is a pressure regulator 103. The outside of the pressure regulator 103 is in contact with the contact component 108 to improve the protection effect on the pressure regulator 103. The connection head component 106 is a T-shaped shaft structure and is inserted into the inside of the pulling groove 105 for connection. On both sides of the front end of the device body 1, a connection component 104 is welded respectively. Inside each connection component 104, a pulling groove 105 is penetrated. The outer end cross-section of the pulling groove 105 with a circular inner side is a T-shaped structure. The connection head component 106 is inserted into the outer end inside of the pulling groove 105 to improve the connection effect.

[0026] In the embodiment of the present disclosure, as Figure 5 with Figure 6 shown, a fixing plate structure 201 is welded to the side of the chassis structure 2. The fixing plate structure 201 is connected to the new energy vehicle through bolts to stably fix the device body 1 for use. On both sides of the top of the chassis structure 2, two guide grooves 202 in the shape of T are respectively opened to enable the pushing head 205 to freely slide and displace inside. The adjusting structure 204 penetrates through the two guide grooves 202, and the threaded section of the adjusting structure 204 is inside the guide grooves 202. Two contact blocks 203 made of flexible rubber are adhesively fixed to the top of the chassis structure 2. The top of the contact blocks 203 is in contact with the bottom of the device body 1 and supports the device body 1 to improve the stability of the device body 1. A T-shaped pushing head 205 is slidably installed inside the guide grooves 202. At the top of each pushing head 205, there is a rectangular force-bearing plate structure 206. The force-bearing plate structure 206 is slidably connected to the force-bearing block 207. A spring is sleeved on the outside of the side of the force-bearing block 207. The outer end of the spring is in contact with the side of the force-bearing plate structure 206. With the elasticity of the spring, an elastic clamping effect is maintained to improve the stability of fixation. The tops of the two force-bearing blocks 207 are welded and fixed to a fixing belt structure 208. The fixing belt structure 208 made of elastic metal is in the shape of a circular ring and clamps the device body 1 for stable fixation. The fixing belt structure 208 is embedded inside the positioning groove 101 and is in contact with the anti-slip groove 102.

[0027] Working principle of this embodiment: When the device body 1 needs to be used, the device body 1 is controlled in advance to be placed above the chassis structure 2. At the same time, the device body 1 is inserted into the inside of the fixing belt structure 208, so that the fixing belt structure 208 is aligned with the positioning groove 101. Then, the adjusting structure 204 is controlled to rotate. The adjusting structure 204 controls the displacement of the pushing head 205 through the thread. The pushing head 205 squeezes the stress block 207 and the fixing belt structure 208 to move, so that the fixing belt structure 208 is embedded into the positioning groove 101 to clamp and fix the device body 1, improving the fixing effect on the device body 1. After the device body 1 becomes loose, the vehicle owner can control the adjusting structure 204 to rotate by himself, so that the adjusting structure 204 controls the displacement of the pushing head 205 through the thread to generate a force to tighten the fixing belt structure 208, conveniently restoring the fixing effect. At the same time, the support plate assembly 107 and the contact assembly 108 are outside the pressure regulator 103. When the pressure regulator 103 encounters a collision, the support plate assembly 107 and the contact assembly 108 improve the protection effect to prevent the pressure regulator 103 from being damaged.
