Detailed Description

Hereinafter, a vehicle according to an embodiment of the present utility model will be described in detail with reference to fig. 1 to 4. Fig. 1 is a schematic view of a vehicle according to an embodiment of the present utility model, fig. 2 is a schematic view of an enclosed space according to a first embodiment of the present utility model, fig. 3 is a sectional view of an enclosed space according to a second embodiment of the present utility model, and fig. 4 is a sectional view of an enclosed space according to a third embodiment of the present utility model.

As shown in fig. 1, a vehicle 100 according to an embodiment of the utility model may include a vehicle body 10 and a chassis 20. As shown in fig. 2, at least one of the vehicle body 10 and the chassis 20 may include an enclosed space 31, and an opening (not shown) for filling clean energy fuel into the enclosed space 31 is provided on a side wall 31a of the enclosed space 31. The clean energy fuel may be stored in the enclosed space 31 in gaseous, liquid or solid form.

The vehicle body 10 and the chassis 20 are both main components for constituting the vehicle body of the vehicle 100. That is, the vehicle 100 according to the present utility model can directly use the vehicle body (body, chassis) itself as a container storing clean energy fuel. Thus, it is advantageous to increase the carrying amount of clean energy fuel in the vehicle, thereby increasing the driving range of the vehicle, compared with the case of storing high-pressure gas using a gas tank (a tank additionally attached to a vehicle body) in the related art. In addition, since the vehicle body (body, chassis) itself is used as a container for storing clean energy fuel without using an additional air tank for storing clean energy fuel, occupation of the vehicle body space is reduced, and thus, space for storing other objects of the vehicle can be increased.

As an example, the vehicle body 10 may include at least one of a front compartment 11, a cab 12, a cargo box 13, and a cargo box floor 14, and the chassis 20 may include stringers 21.

According to an embodiment of the present utility model, at least one of the front compartment 11, the cargo bed 14, and the stringers 21 of the chassis 20 of the body 10 may form an enclosed space 31 to serve as a container for storing clean energy fuel.

The enclosed space 31 shown in fig. 2 is formed by forming the cargo bed 14 into an enclosed structure, with the housing of the cargo bed 14 forming the side wall 31a of the enclosed space 31. An opening (not shown) may be provided in the sidewall 31a of the enclosed space 31 for filling the enclosed space 31 with clean energy fuel. The opening may be a sealed port that may be sealed to prevent clean energy fuel from leaking from the enclosed space 31.

Although fig. 2 shows the cargo box base 14 forming the enclosed space 31, the utility model is not limited thereto and the front compartment 11 or the stringers 21 may also form the enclosed space 31. In this case, the front cabin 11 or the shell of the stringers 21 may form the side wall 31a of the closed space 31.

Any two or three of the front compartment 11, the cargo bed base 14, and the stringers 21 may form an enclosed space 31 to serve as a container for storing clean energy fuel, according to embodiments of the present utility model. In this case, by providing at least two containers to store the clean energy fuel, the carrying amount of the clean energy fuel can be further increased, and the mileage of the vehicle can be increased.

According to an embodiment of the present utility model, the front compartment 11, the cargo bed 14, and the stringers 21 may integrally form an enclosed space 31 (as shown in fig. 2, the enclosed space 31 is formed by the entire shell of the cargo bed 14). However, the present utility model is not limited thereto, and at least one of the front compartment 11, the cargo bed 14, and the side rails 21 may include the enclosed space 31, that is, only a portion (rather than the entirety) of at least one of the front compartment 11, the cargo bed 14, and the side rails 21 forms the enclosed space 31.

According to an embodiment of the utility model, the side wall 31a enclosing the enclosed space 31 may be a shell constituting the front compartment 11, the cargo bed 14 or the stringers 21 themselves. When only a portion (rather than the entirety) of the front compartment 11, the cargo bed 14, or the stringers 21 form the enclosed space 31, an additional shell may also be provided inside the front compartment 11, the cargo bed 14, or the stringers 21 to form the enclosed space 31 in conjunction with the shell that forms the front compartment 11, the cargo bed 14, or the stringers 21 themselves.

According to an embodiment of the present utility model, the side wall 31a of the closed space 31 is made of metal, for example, alloy steel or aluminum. According to an embodiment of the present utility model, the thickness of the sidewall 31a may be designed according to the storage pressure of the clean energy fuel. For example, the thickness of the sidewall 31a may allow for storage of clean energy fuel at a pressure of 5-70 MPa. However, the storage pressure of the clean energy fuel is not limited thereto. Embodiments of the present utility model are preferred for low pressure storage for clean energy fuel storage because low pressure storage is highly safe.

According to embodiments of the present utility model, the clean energy fuel may be hydrogen, methane, natural gas, or the like. However, examples of the clean energy fuel in the present utility model are not limited thereto as long as the pollutant discharge amount of the clean energy fuel is lower than that of the gasoline or diesel fuel.

According to an embodiment of the present utility model, as shown in fig. 2, an air bag 32 may be further provided in the closed space 31, and clean energy fuel is charged into the air bag 32, and an air charging hole (not shown) is provided on the air bag 32, the air charging hole penetrating from an opening provided on the sidewall 31a for charging clean energy fuel (e.g., hydrogen) into the air bag 32.

According to an embodiment of the present utility model, as shown in fig. 2, the shape of the airbag 32 may substantially conform to the shape of the sidewall 31a of the closed space 31 to increase the storage space of the airbag 32. However, the present utility model is not limited thereto, and the shape of the airbag 32 may be different from the shape of the side wall 31a of the closed space 31.

According to the embodiment of the present utility model, by providing the air bag 32 storing clean energy fuel inside the closed space 31, at least the following three technical effects can be achieved. First, the bladder 32 itself has a relatively good flexibility and has a pressure within it when filled with clean energy fuel, which makes it easier for the clean energy fuel within the container to be expelled. Second, by providing the air bags 32, the storage pressure of the clean energy fuel can be increased, and the storage amount of the clean energy fuel can be further increased. Third, by providing the airbag 32, clean energy fuel leakage can be prevented, and storage safety of the enclosed space 31 can be improved.

In addition, in the case where the air bag 32 is provided, the thickness of the side wall 31a of the closed space 31 can be reduced accordingly, and the thickness of both the side wall 31a and the air bag 32 can be designed according to the storage pressure of the clean energy fuel.

As an example, the bladder 32 may be made of a rubber material to provide elasticity to the bladder 32.

The enclosed space shown in fig. 3 and 4 is also provided with a self-repairing coating 33.

As shown in fig. 3, according to an embodiment of the present utility model, the inside of the balloon 32 may be provided with a self-repairing coating 33, and the self-repairing coating 33 is used to seal the perforation generated after the balloon 32 is damaged. When the sidewall 31a of the closed space 31, the balloon 32 and the self-repairing coating 33 are pierced by foreign substances, the self-repairing coating 33 can function to automatically seal the piercing.

For example, when the side wall 31a and the balloon 32 are pierced, the self-repairing coating 33 provided inside the balloon 32 is pressed toward the perforation by the air pressure inside the balloon 32 to be gathered, and the self-repairing coating 33 is cured by encountering the outside air at the perforation, so that the self-repairing coating 33 seals the perforation of the balloon 32 (or the perforation of both the balloon 32 and the side wall 31 a). For example, when all three of the sidewall 31a, the balloon 32 and the self-repairing coating 33 are pierced, the self-repairing coating 33 can gather and tightly wrap the foreign materials toward the piercing under the pressure and seal the piercing.

According to embodiments of the present utility model, the self-healing coating 33 may be a tacky material (e.g., a solid gel, a liquid gel). The viscous material of the self-healing coating 33 may adhere to the surface of the foreign object and/or the perforations to prevent clean energy fuel from leaking along the surface of the foreign object.

Although an example in which the self-repairing coating 33 is provided inside the airbag 32 is shown in fig. 3, the present utility model is not limited thereto, and the self-repairing coating 33 may be provided outside the airbag 32, that is, between the airbag 32 and the side wall 31a of the closed space 31. When the self-repairing coating 33 is provided outside the airbag 32, the self-repairing coating 33 may function similarly to when provided inside the airbag 32. In addition, when the self-repairing coating 33 is provided outside the airbag 32, the material of the self-repairing coating 33 may be pushed toward the side wall 31a of the closed space 31 by the pressure of the airbag 32, and thus it may be easier to seal the perforations on the side wall 31a.

In addition, according to another example, a self-repairing coating 33 is provided on both the inside of the balloon 32 and the outside of the balloon 32 to achieve a more excellent self-sealing effect. For example, when the foreign matter pierces the sidewall 31a, the airbag 32, and the self-repair coating 33 provided outside and inside the airbag 32, the self-repair coating 33 provided inside the airbag 32 may adhere to the surface of the foreign matter and/or the perforated portion of the airbag 32, and the self-repair coating 33 provided outside the airbag 32 may adhere to the surface of the foreign matter and/or the perforated portion of the sidewall 31a.

According to an embodiment of the present utility model, the thickness of the self-healing coating 33 is 30% to 200% of the thickness of the airbag 32. When the thickness of the self-repairing coating 33 is less than 30% of the thickness of the airbag 32, the thickness of the self-repairing coating 33 is too small to seal the perforation. When the thickness of the self-repairing coating 33 is 200% of the thickness of the airbag 32, the effect of sealing the perforation is already excellent, so in order to save the material of the self-repairing coating, reduce the thickness of the self-repairing coating to increase the storage space of the clean energy fuel, the thickness of the self-repairing coating 33 does not exceed 200% of the thickness of the airbag 32.

As shown in fig. 4, according to an embodiment of the present utility model, the balloon 32 may include a balloon outer layer 32a and a balloon inner layer 32b, and a self-repairing coating 33 may be disposed between the balloon outer layer 32a and the balloon inner layer 32b, and the self-repairing coating 33 is used to seal the perforation generated after the balloon 32 is damaged.

For example, when the sidewall 31a of the closed space 31 and the airbag outer layer 32a are pierced and the self-repair coating 33 is not pierced, the self-repair coating 33 may be pressed to the perforation of the airbag outer layer 32a (or the perforation of both the sidewall 31a and the airbag outer layer 32 a), thereby sealing the perforation, preventing the perforation from becoming a weak point for sealing the clean energy fuel.

For example, when the sidewall 31a of the enclosed space 31, the balloon outer layer 32a, the self-healing coating 33, and the balloon inner layer 32b are pierced, the material of the self-healing coating 33 may tightly encapsulate the foreign matter to seal the perforations in the self-healing coating 33. In addition, the material of the self-healing coating 33 may also be extruded at the perforations of the balloon outer layer 32a and the balloon inner layer 32b, thereby sealing the perforations in the balloon outer layer 32a and the balloon inner layer 32 b. In addition, the self-healing coating 33 may be extruded to the perforations of the sidewall 31a, thereby sealing the sidewall 31a.

According to an embodiment of the present utility model, as in the example of fig. 3, the self-healing coating 33 may be a viscous material (e.g., a solid gel, a liquid gel). The viscous material of the self-healing coating 33 may adhere to the surface of the foreign object and/or the perforations to prevent clean energy fuel from leaking along the surface of the foreign object.

According to the embodiment of the present utility model, the thickness of the self-repair coating layer 33 is 30% to 100% of the thickness of the balloon outer layer 32a or the thickness of the balloon inner layer 32 b. When the thickness of the self-repairing coating 33 is less than 30% of the thickness of the balloon outer layer 32a or the thickness of the balloon inner layer 32b, the thickness of the self-repairing coating 33 is too small to seal the perforation. When the thickness of the self-repairing coating layer 33 is 100% of the thickness of the airbag outer layer 32a or the thickness of the airbag inner layer 32b, the effect of sealing the perforation is already excellent, so in order to save the material of the self-repairing coating layer, the thickness of the self-repairing coating layer is reduced to increase the storage space of the clean energy fuel, the thickness of the self-repairing coating layer 33 does not exceed 100% of the thickness of the airbag outer layer 32a or the thickness of the airbag inner layer 32 b.

According to embodiments of the utility model, the hardness of the balloon outer layer 32a may be greater than the hardness of the balloon inner layer 32 b. The hardness of the balloon outer layer 32a is greater than that of the balloon inner layer 32b, so that the balloon outer layer 32a can be prevented from being pierced by foreign matter, and the safety of storing clean energy fuel can be improved. The inner bag layer 32b is less stiff and thus more elastic than the outer bag layer 32a, which can improve the storage of clean energy fuel on the one hand, and can apply a greater pressing force to the self-repairing coating 33 to more easily seal the perforation when the outer bag layer 32a is pierced by foreign matter on the other hand.

As described above, the vehicle according to the embodiment of the utility model can directly utilize the vehicle body itself as a container storing clean energy fuel. Thus, it is advantageous to increase the carrying amount of the clean energy fuel in the vehicle and thus increase the mileage of the vehicle, compared to the case of storing high pressure using a gas tank (a tank attached to a vehicle body, unlike the vehicle body) in the related art.

In addition, through setting up the gasbag of storing clean energy fuel in the enclosure space inside, can make clean energy fuel in the container more easily be discharged, can improve clean energy fuel's storage pressure, further improve clean energy fuel's storage capacity, can prevent clean energy fuel leakage, improve the storage security.

In addition, through the self-repairing coating, the perforation generated after the air bag is damaged can be sealed, so that the storage safety can be further improved. While exemplary embodiments of the present utility model have been particularly described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present utility model as defined by the appended claims. For example, while embodiments of the present utility model have been described in the foregoing description with reference to filling clean energy fuel into an enclosed space and an air bag, those skilled in the art will appreciate that the teachings of the present utility model are equally applicable in the case of filling non-clean energy fuel (e.g., gasoline, diesel) into an enclosed space and/or an air bag.
