[0041] Embodiment 1

[0042] As Figures 1-2 shown, the CNG cylinder 4 arrangement mechanism provided by the present application comprises: a sliding assembly 2 and a fixed frame 3.

[0043] The sliding assembly 2 is arranged in the vehicle 1, specifically, the sliding assembly 2 can adopt mutually matched guide rails 201 and sliding blocks 202, the sliding rails are provided with at least two, the guide rails 201 are fixed in the vehicle 1, the sliding blocks 202 are connected and fixed with the fixed frame 3, the fixed frame 3 is slidingly connected in the guide rails 201 of the sliding assembly 2 through the sliding blocks 202, specifically, the sliding blocks 202 are fixed at the bottom of the fixed frame 3, the fixed frame 3 is fixed with the cylinder 4, and the fixed frame 3 extends outside the vehicle 1 along the sliding direction of the sliding assembly 2.

[0044] The fixed frame 3 is slidingly connected on the vehicle 1 by the sliding assembly 2, the cylinder 4 is fixed in the fixed frame 3, and the cylinder 4 is accommodated in the vehicle 1 or extends outside the vehicle 1 in a sliding manner, when refueling is needed, it can be extended outside the vehicle 1, without the need to disassemble the entire cylinder 4, convenient and fast operation.

[0045] A handle 9 is arranged on the outer side of the fixed frame 3, and the fixed frame 3 can be pulled out and pushed in through the handle 9.

[0046] To ensure that the fixed frame 3 is supported when it is extended and suspended, the support device 5 is arranged at the bottom of the fixed frame 3 and is used to contact the ground when the fixed frame 3 is extended outside the vehicle 1. Specifically, the support device 5 is arranged at the bottom of the fixed frame 3 near the outer side. When the fixed frame 3 is extended outside the vehicle 1 through the sliding assembly 2, the support device 5 plays a supporting role to avoid the fixed frame 3 and the gas cylinder 4 thereon from being too heavy to damage the sliding assembly 2.

[0047] Specifically, the support device 5 is arranged in two pairs, and the two support devices 5 are arranged at the two sides of the bottom of the fixed frame 3. The support device 5 includes a hinged seat 501 and an extension rod 502.

[0048] The hinged seat 501 is mounted at the bottom of the fixed frame 3, one end of the extension rod 502 is hinged to the hinged seat 501, and the other end is used to contact the ground. The rotation plane of the extension rod 502 and the hinged seat 501 is perpendicular to the sliding direction of the sliding assembly 2. Through the cooperation of the hinged seat 501 and the extension rod 502, when the fixed frame 3 needs to be supported when it is extended outside the vehicle, the extension rod 502 is stretched and expanded to play a supporting role. When the fixed frame 3 does not need to be supported when it is retracted into the vehicle, the extension rod 502 is retracted and folded close to the fixed frame 3, which is convenient for placing in the vehicle.

[0049] To facilitate the storage of the extension rod 502, the extension rod 502 includes at least two rod bodies. The plurality of rod bodies are sequentially and fixedly connected. By arranging a plurality of rod bodies, the length of the extension rod 502 can contact the ground. In addition, the rod bodies are detachably connected, and the plurality of rod bodies can be more easily accommodated under the fixed frame 3 when stored.

[0050] Specifically, the connection mode of the plurality of rod bodies can be sequentially sleeved and fixed by screw connection. In use, the plurality of rod bodies can be sequentially connected and fixed to be expanded for use after the fixed frame 3 is pulled out. When folded, the plurality of rod bodies can be disassembled and placed in the vehicle 1 before the fixed frame 3 is retracted into the vehicle. Alternatively, the plurality of rod bodies can be sequentially sleeved and locked by a lock spring when extended. In use, the plurality of rod bodies are sequentially stretched to extend the extension rod 502. The lock spring fixes and limits the axial movement of each rod body. When folded, the extension rod 502 is sequentially retracted after the lock spring is pressed, and is accommodated in the gap between the bottom of the fixed frame 3 and the vehicle 1 through the hinged seat 501.

[0051] As shown in Figure 3 , 4 To ensure that the extension rod 502 can remain stable after being expanded, the hinged seat 501 is provided with a limiting block 503. The limiting block 503 is located away from the folding direction of the extension rod 502. In this embodiment, the limiting block 503 is located outside the extension rod 502 and contacts the limiting block 503 when the extension rod 502 is expanded.

[0052] Specifically, the bottom edge of the abutment surface of the limiting block 503 near the telescopic rod 502 is inclined outward, that is, the abutment surface is set to be inclined, so as to abut and limit the telescopic rod 502 when the telescopic rod 502 is extended.

[0053] By using the setting of the limiting block 503, when the telescopic rod 502 is unfolded, it abuts against the abutting surface of the limiting block 503, which plays a limiting role and prevents the telescopic rod 502 from being fixed by the limiting block 503 after it is unfolded around the hinge seat 501. The abutting surface is set at an angle, so that the bottom end of the telescopic rod 502 is expanded outward, which can better support it on the ground.

[0054] To ensure that the telescopic rod 502 does not rotate arbitrarily with the hinge seat 501 when it is extended and retracted, a first magnetic element for attracting the telescopic rod 502 is provided on the side of the limiting block 503 near the telescopic rod 502, and a second magnetic element for attracting the telescopic rod 502 is provided on the inner bottom of the hinge seat 501. The telescopic rod 502 is configured to be made of iron that attracts the first and second magnetic elements, or to have a magnetic element that attracts the first and second magnetic elements.

[0055] By setting a first magnetic component and a second magnetic component, the telescopic rod 502 is attracted by magnetic force, so that the telescopic rod 502 can play a fixing role after it is extended and retracted. Specifically, when the telescopic rod 502 is retracted, the telescopic rod 502 is attracted to the second magnetic component, so that the telescopic rod 502 remains attached to the bottom of the fixing frame 3. When the telescopic rod 502 is extended, the telescopic rod 502 is attracted to the first magnetic component, so that the telescopic rod 502 is attached to the limiting block 503 and remains in the extended state.

[0056] In another embodiment, a universal brake wheel is connected to one end of the telescopic rod 502 away from the hinge seat 501. The universal brake wheel is detachably connected to the end of the telescopic rod 502. The universal brake wheel is not shown in the figure.

[0057] By installing wheels at the bottom of the telescopic rod 502, it is possible to extend the telescopic rod 502 in advance and make contact with the ground as early as possible. When the fixed frame 3 moves on the sliding component 2, it can play a supporting role. That is, during the pulling out process, the telescopic rod 502 extends and the universal brake wheel contacts the ground to play a supporting role. At the same time, the universal brake wheel can keep the bottom of the telescopic rod 502 slidingly connected to the ground during the pulling out process. After being pulled out to the end, the universal brake wheel can also brake and fix it.

[0058] To ensure the stability of the mounting bracket 3 inside the vehicle, a first locking hook 7 is provided on the sliding assembly 2, and a first locking buckle 6 matching the first locking hook 7 is provided on the side of the mounting bracket 3. The first locking buckle 6 is located on the mounting bracket 3 near the outside of the vehicle. The first locking buckle 6 is used to retract and connect with the first locking hook 7 when the mounting bracket 3 is retracted into the vehicle 1. After the first locking buckle 6 and the first locking hook 7 are retracted, the mounting bracket 3 on the sliding assembly 2 can be prevented from sliding back and forth along the sliding assembly 2, and it can be kept fixed in the vehicle.

[0059] In addition, to ensure that the fixing frame 3 remains stable after being pulled out into place, and that the fixing frame 3 and the sliding component 2 do not slide relative to each other and remain fixed, a second locking buckle 8 is provided on the side of the fixing frame 3 at a distance from the first locking buckle 6. The second locking buckle 8 is located on the fixing frame 3 near the end inside the vehicle. The second locking buckle 8 is used to lock and connect with the first locking hook 7 when the fixing frame 3 extends out of the vehicle 1.

[0060] Among them, there are two pairs of first latches 6 and second latches 8, which are located on both sides of the fixing frame 3 respectively. Correspondingly, there are two first locking hooks 7, which are located on both sides of the sliding component 2.

[0061] In practical use, open the first latch 6 and the first hook 7 on the fixed frame 3, pull out the fixed frame 3, and during the pulling process, unfold the telescopic rod 502. When the telescopic rod 502 is stretched to the end, the universal brake wheel at the bottom of the telescopic rod 502 contacts the ground. After the fixed frame 3 is pulled out to the end, use the second latch 8 to lock with the first hook 7 to prevent the fixed frame 3 from sliding on the sliding component. At this time, perform the air replenishment operation. After the air replenishment is completed, release the second latch 8 and push the fixed frame 3 inward. When the fixed frame 3 retracts into the vehicle, retract the telescopic rod 502 and close the telescopic rod 502 to the bottom position of the fixed frame 3. After pushing the fixed frame 3 into place, lock the first latch 6 and the first hook 7 to fix it.
