The following description is provided for illustrative purposes, and other advantages and features of the present invention will become apparent to those skilled in the art from the following detailed description.

Please refer to fig. 1-2. It should be understood that the structure, ratio, size and the like shown in the drawings of the present specification are only used for matching with the content disclosed in the specification, so as to be known and read by those skilled in the art, and are not used for limiting the limit conditions that the present invention can be implemented, so that the present invention does not have the essential significance in the technology, and any modification of the structure, change of the ratio relationship or adjustment of the size should still fall within the scope that the technical content disclosed in the present invention can cover without affecting the function that the present invention can produce and the purpose that can be achieved. Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present specification are for convenience of description, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof may be made without substantial technical changes, and the present invention is also regarded as the scope of the present invention.

The following examples are for illustrative purposes only. The various embodiments may be combined, and are not limited to what is presented in the following single embodiment.

Referring to fig. 1 and 2, the present invention provides an embodiment of a gas cylinder protective case for a fuel vehicle, including: the device comprises a first end cover 1, a middle cover 2 and a second end cover 3, wherein the upper end and the right end of the first end cover 1 are of an open structure; the upper end and the left and right ends of the middle cover 2 are of an opening structure; the upper end and the left end of the second end cover 3 are of an open structure; the first end cover 1 and the second end cover 3 are respectively fixed at two ends of the middle cover 2 and are communicated with each other to form an accommodating cavity 4, and the accommodating cavity 4 is used for accommodating a gas cylinder; the bottom of the accommodating cavity 4 is provided with at least one water leakage hole 41. The shape of first end cover 1, middle lid 2 and second end cover 3 can also be the arc structure in figure 1 for the rectangle, and the setting of arc structure can match with the appearance of gas cylinder on the one hand, and its material utilization ratio of on the other hand is with low costs and occupation space is little, can reduce the scratch of protective housing and other structures in the external world to better protection gas cylinder. Through the arrangement of the water leakage hole 41, water flowing out of the automobile or water formed by condensation of the gas cylinder can flow out of the water leakage hole 41 at the bottom of the accommodating cavity 4.

Referring to fig. 1, the present invention provides an embodiment of an arrangement manner of the water leakage holes 41, the number of the water leakage holes 41 is more than one, and the water leakage holes 41 are arranged in the left and right direction. The hole 41 that leaks arranges on left and right sides orientation, and can effectually avoid because the ponding problem that the slope leads to when the protective housing installation, in order to reach better water leakage effect, can also set up the hole 41 that leaks in the bottom of first end cover 1 and second end cover 3.

Referring to fig. 1, the present invention provides an embodiment of a fixing manner of a protective shell and a chassis, wherein the front end and the rear end of the middle cover 2 are both provided with a flange 21, and the flange 21 is provided with a plurality of mounting holes 211. The setting of turn-ups 21 structure makes it make conveniently, and it can directly turn over a book and form for the protective housing when for the steel material, and when the protection material was the plastics material, it can be through mould integrated into one piece. Optionally, the mounting hole 211 is a strip-shaped hole, and a long side of the mounting hole 211 is in the left-right direction. Mounting hole 211 is the bar hole for when installing protective housing cover on the gas cylinder and with the chassis, it can pass the threaded hole on mounting hole 211 and screw in chassis through the screw and have, because the threaded hole is seted up or there is the error in seting up of mounting hole 211, the adaptation can be realized in the bar hole, and the screw can be transferred to on the length direction in bar hole, corresponds in order to realize the threaded hole on mounting hole 211 and chassis, realizes dismantling fixedly.

Referring to fig. 1, the first end cap 1 is matched with the tail of the gas cylinder, the second end cap 3 is matched with the head of the gas cylinder, and a natural gas leakage alarm sensor 31 is arranged on the second end cap 3. Natural gas leakage alarm sensor 31 itself is prior art, and here is only with its application in protective housing department, and current natural gas leakage alarm sensor 31 all installs at the burning end, and does not set up the gas cylinder position, and this embodiment sets up natural gas leakage alarm sensor 31 on the protective housing for it can follow the source and monitor the gas leakage condition, thereby makes the fuel car have higher security performance. Optionally, the natural gas leakage warning sensor 31 is located inside the second end cap 3. The inner side of the protective shell can effectively separate the natural gas leakage alarm sensor 31 from the outside, so that the natural gas leakage alarm sensor has better detection accuracy, and can also play a role in protecting the natural gas leakage alarm sensor 31.

Referring to fig. 1, an avoiding groove 22 is formed in the inner side of the middle cover 2, at least one avoiding groove 22 is formed in the left and right direction of the middle cover 2, and the avoiding groove is formed along the top-to-bottom direction. The gas cylinder is hooped on the chassis, the avoiding groove 22 can effectively enable the hoop to be arranged in the avoiding groove 22, so that the protective shell is better matched with the gas cylinder, stress concentration can be reduced, and when the outer side of the protective shell is scratched, force transmitted to the gas cylinder by the protective shell can be effectively dispersed.

Referring to fig. 1, a nameplate viewing port 23 is disposed on an outer side of the middle cap 2, and the nameplate viewing port 23 corresponds to a nameplate of the gas cylinder. Because the user state to the gas cylinder needs carry out periodic inspection in order to accord with the national standard, through setting up data plate viewing aperture 23, its when the inspection, need not dismantle the protective housing, it directly can through the observation of data plate viewing aperture 23. For better protection, a transparent window or a window of a barrier structure can also be arranged in the nameplate viewing opening 23.

A fuel vehicle comprising a gas cylinder protective case for a fuel vehicle according to any one of the above embodiments; the gas cylinder is hooped on the base plate, and the middle cover 2 is fixed on the base plate.

To sum up, the utility model discloses a cooperation of first end cover 1, middle lid 2 and second end cover 3 can effectual protection gas cylinder, avoids the gas cylinder to be scraped, has reduced safe risk, and sets up the hole 41 that leaks through the bottom that holds chamber 4 for the hydroenergy that water or gas cylinder itself condensation formed that the car flows can be from holding the hole 41 that leaks of chamber 4 bottom and flowing.

Therefore, the utility model effectively overcomes various defects in the prior art and has high industrial utilization value.
