Description

Technical Field

[0001] This utility model relates to the field of hydrogen fuel cell technology for hydrogen fuel cell vehicles, specifically an integrated device for hydrogen fuel cell vehicles. Background Technology

[0002] Hydrogen fuel cell vehicles, as a type of new energy vehicle different from pure electric vehicles, also face overall vehicle safety issues. Hydrogen is considered one of the most promising clean energy sources for the future. Hydrogen fuel cells convert the chemical energy released by the chemical reaction of hydrogen and oxygen into electrical energy without combustion, boasting high energy conversion efficiency and zero emissions. It is one of the main development directions for future new energy clean energy vehicles. However, the development of hydrogen power faces many challenges, one of the key difficulties being the storage of hydrogen in vehicles.

[0003] For example, Chinese Patent Publication No. CN220129942U discloses the following technical solution: This utility model relates to the field of hydrogen fuel cell assembly for hydrogen-powered vehicles, specifically a hydrogen fuel cell assembly integration device for hydrogen-powered vehicles, including an integration frame, a support frame, and a hydrogen cylinder. The support frame is located inside the integration frame, and a guide rail is fixedly installed at the top of the support frame. A central locking block is slidably installed on the outer side of the guide rail. The hydrogen cylinder is engaged between adjacent central locking blocks. A positioning pin is installed at the top of the central locking block, and the positioning pin passes through the central locking block. The positioning pin is rotatably connected to the central locking block. This hydrogen fuel cell assembly integration device for hydrogen-powered vehicles, through the central locking block, positioning pin, movable limiting clamp, and guide rail, allows the central locking block on the guide rail to be adjusted to move and fit against the outer side of the hydrogen cylinder, completing the assembly by close contact. This reduces the gaps between the hydrogen cylinder and the integration frame, making the connection and use more stable.

[0004] However, in the existing hydrogen fuel cell assembly devices for hydrogen vehicles, the central locking block, positioning pin, movable limit clamp, and guide rail are used. By adjusting the position of the central locking block on the guide rail, the central locking block can be moved to fit against the outside of the hydrogen cylinder and close to the positioning pin and positioning hole to complete the assembly. However, there is always a gap between the positioning holes, which cannot be precisely adjusted according to the size of the hydrogen cylinder. This results in the inability to accurately fit the central locking block against the outside of the hydrogen cylinder, lacking a certain degree of precision. Utility Model Content

[0005] In view of the problems in the related technologies, this utility model proposes an integrated device for hydrogen tank assembly in hydrogen-powered vehicles to overcome the aforementioned technical problems existing in the existing related technologies.

[0006] Therefore, the specific technical solution adopted by this utility model is as follows:

[0007] An integrated device for hydrogen fuel cell vehicles includes an integrated frame, a hydrogen cylinder body, and a movable support block. The integrated frame has a placement groove inside, and a protective pad is fixedly connected inside the placement groove. Support rods are fixedly connected to both sides of the placement groove, and a sliding rod is fixedly connected between the support rods. The movable support block has a sliding groove inside, and the movable support block is slidably connected to the outer wall of the sliding rod through the sliding groove. The movable support block also has a movable groove inside, and a circular block is fixedly connected to one inner wall of the movable groove. A plastic buckle is arranged in a circumferential array on one side of the circular block. A threaded groove is formed on one side of the movable support block, and a bolt is threaded into the groove. One end of the plastic buckle has a first sliding surface, and the inner side of one end of the bolt has a second sliding surface.

[0008] A further improvement of this utility model is that: the bolt has a through groove inside, the through groove and the sliding groove are adapted to each other, and the sliding groove and the sliding rod are adapted to each other.

[0009] Using the above technical solution, the slide rod in the solution can slide inside the through groove.

[0010] A further improvement of this utility model is that: the number of movable support blocks is several, and they are symmetrically and slidably connected to the outer wall of the slide rod, and the hydrogen cylinder body is located between the movable support blocks.

[0011] A further improvement of this utility model is that: the upper end of the movable support block is provided with a fixed frame, the movable block is slidably connected inside the fixed frame, an insert plate is fixedly connected to the bottom of the movable block, and a slot is provided at the upper end of the movable support block.

[0012] In the above technical solution, the movable block is connected to the upper end of the movable support block through slots and inserts.

[0013] A further improvement of this utility model is that: a fixing groove is provided at the upper end of the support rod, the bottom of both ends of the fixing frame is located inside the fixing groove, a slot is provided on the outer wall of both ends of the fixing frame, and a locking block is provided inside the fixing groove.

[0014] A further improvement of the present invention is that: a slot is provided on one side of the inner wall of the fixing groove, the card block is slidably connected to the inside of the slot, a protrusion is fixedly connected to the outside of the support rod, and a movable cavity is provided inside the protrusion, the movable cavity being connected to the slot.

[0016] Using the above technical solution, the limiting plate in the solution can limit the movement of the card block, so that the card block will not be dislodged from the movable cavity. The return spring can drive the card block to perform a return movement, so that the card block is engaged in the inside of the card slot, thereby making the bottom of both ends of the fixing frame stably fixed in the inside of the fixing slot, thus ensuring the stability of the fixing frame.

[0017] A further improvement of this utility model is that: the end of the card block away from the limiting plate is provided with a first inclined surface, and the bottom of both ends of the fixing frame is provided with a second inclined surface.

[0018] Using the above technical solution, the first and second inclined surfaces are used to rub against each other, so that the locking block slides under the thrust of friction, and the bottom of both ends of the fixing frame can be fully inserted into the fixing groove.

[0019] The beneficial effects of this utility model are as follows:

[0020] 1. By rotating the bolt, the bolt will move under the action of the threaded groove, which will cause the first sliding surface and the second sliding surface to rub against each other. Under the thrust of friction, the plastic buckles will move closer to each other to clamp the sliding rod, thus ensuring the stability of the movable support block. It can be adjusted more precisely according to the size of the hydrogen cylinder body, improving practicality.

[0021] 2. The reset spring can drive the locking block to perform a reset movement, so that the locking block is engaged inside the locking groove, thereby making the bottom of both ends of the fixing frame stably fixed inside the fixing groove, ensuring the stability of the fixing frame, and thus making the hydrogen cylinder body stably fixed.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] According to an embodiment of the present invention, an integrated device for hydrogen cylinder packs in hydrogen-powered vehicles is provided. Example 1:

[0033] like Figure 1-6As shown, the hydrogen fuel cell assembly integration device for a hydrogen fuel cell vehicle according to an embodiment of the present invention includes an integration frame 1, a hydrogen cylinder body 2, and a movable support block 3. The integration frame 1 has a placement groove 101 inside, and a protective pad 102 is fixedly connected inside the placement groove 101. Support rods 103 are fixedly connected to both sides of the placement groove 101, and a sliding rod 5 is fixedly connected between the support rods 103. The movable support block 3 has a sliding groove 302 inside, and the movable support block 3 is slidably connected to the outer wall of the sliding rod 5 through the sliding groove 302. The movable support block 3 has a movable groove 303 inside, and a round block 305 is fixedly connected to the inner wall of one side of the movable groove 303. A plastic buckle 306 is arranged in a circumferential array on one side of the round block 305. A threaded groove 304 is opened on one side of the movable support block 3, and a bolt 308 is threadedly engaged inside the threaded groove 304. A first sliding surface 307 is provided at one end of the plastic buckle 306, and a second sliding surface 3010 is provided on the inner side of one end of the bolt 308.

[0034] In this embodiment, by rotating the bolt 308, the bolt 308 will move under the action of the threaded groove 304, thereby causing the first sliding surface 307 and the second sliding surface 3010 to rub against each other. This causes the plastic buckles 306 to move closer together under the thrust of friction to clamp the sliding rod 5, thereby ensuring the stability of the movable support block 3. This allows for more precise adjustment according to the size of the hydrogen cylinder body 2, improving practicality. Example 2:

[0035] like Figure 1-6 As shown, in the hydrogen fuel cell assembly device for a hydrogen-powered vehicle according to an embodiment of the present invention, a through groove 309 is provided inside the bolt 308, which is adapted to the sliding groove 302. The sliding groove 302 is adapted to the sliding rod 5. There are several movable support blocks 3, which are symmetrically and slidably connected to the outer wall of the sliding rod 5. The hydrogen cylinder body 2 is located between the movable support blocks 3. A fixing frame 4 is provided at the upper end of the movable support block 3. A movable block 403 is slidably connected inside the fixing frame 4. An insert plate 404 is fixedly connected to the bottom of the movable block 403. A slot 301 is provided at the upper end of the movable support block 3. A fixing groove 104 is provided at the upper end of the support rod 103. The bottoms of both ends of the fixing frame 4 are located inside the fixing groove 104. A slot 401 is provided on the outer wall of both ends of the fixing frame 4. A locking block 106 is provided inside the fixing groove 104.

[0036] In this embodiment, the slide bar 5 can slide inside the through groove 309, and the movable block 403 is connected to the upper end of the movable support block 3 through the slot 301 and the insert plate 404. Example 3:

[0037] like Figure 1-6As shown, in the hydrogen fuel cell assembly device for hydrogen fuel cell vehicles according to an embodiment of the present invention, a slot is provided on one side of the inner wall of the fixing groove 104, the locking block 106 is slidably connected to the inside of the slot, a protrusion 105 is fixedly connected to the outside of the support rod 103, a movable cavity is provided inside the protrusion 105, the movable cavity is connected to the slot, one end of the locking block 106 is fixedly connected to a limiting plate 108, the limiting plate 108 is slidably connected to the inside of the movable cavity, a return spring 109 is fixedly connected to the end of the limiting plate 108 away from the locking block 106, a pull rod 1010 is fixedly connected to the end of the limiting plate 108 away from the locking block 106, a first inclined surface 107 is provided at the end of the locking block 106 away from the limiting plate 108, and a second inclined surface 402 is provided at the bottom of both ends of the fixing frame 4.

[0038] In this embodiment, the limiting plate 108 can limit the locking block 106, preventing the locking block 106 from disengaging from the movable cavity. The reset spring 109 can drive the locking block 106 to perform a reset movement, causing the locking block 106 to engage inside the locking groove 401. This ensures that the bottom ends of the fixing frame 4 are stably fixed inside the fixing groove 104, thereby guaranteeing the stability of the fixing frame 4. The first inclined surface 107 and the second inclined surface 402 are used for mutual friction, causing the locking block 106 to slide under the thrust of friction, allowing the bottom ends of the fixing frame 4 to be fully inserted into the fixing groove 104.

[0039] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0040] In practical applications, the movable support block 3 is slidable on the slide rod 5. After adjusting to the desired position, the bolt 308 is rotated. The bolt 308 slides into the threaded groove 304 under the action of the threaded groove 304, causing the first sliding surface 307 and the second sliding surface 3010 to rub against each other. This causes the plastic clips 306 to move closer together under the thrust of friction, clamping the slide rod 5 and thus fixing the movable support block 3. Then, the hydrogen cylinder body 2 is placed between the movable support blocks 3. The fixing bracket 4 is then installed, with the insert plate 404 aligned with the slot 301, and the bottom of both ends of the fixing bracket 4 aligned with the fixing groove 104 and inserted. During the insertion of the part into the fixing groove 104, the first inclined surface 107 and the second inclined surface 402 will rub against each other, causing the locking block 106 to slide under the thrust of friction, and driving the return spring 109 to compress. After the bottom of both ends of the fixing frame 4 is fully inserted into the fixing groove 104, the return spring 109 can drive the locking block 106 to perform a reset movement, so that the locking block 106 is locked into the inside of the slot 401, thereby making the bottom of both ends of the fixing frame 4 stably fixed inside the fixing groove 104, and thus fixing the hydrogen cylinder body 2. If the fixing frame 4 needs to be removed, pull the lever 1010 to drive the locking block 106 to be pulled out of the slot 401, and then the fixing frame 4 can be removed.

[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
