The housing includes an outer portion, an inner portion, an air-flow channel, a plurality of air inlets, an air outlet, and a spoiler surface or a spoiler. The air-flow channel is disposed between the outer portion and the inner portion of the housing. The air inlets are disposed on the outer portion of the housing, and the air outlet is disposed at a rear of the outer portion of the housing. The air-flow channel communicates with the air inlets and the air outlet. The spoiler surface or the spoiler is disposed on a bottom of the outer portion of the housing, a top of the inner portion of the housing, or both the bottom of the outer portion and the top of the inner portion of the housing, for extending path of the air. ## Claims ### Claim 1 A vehicle, comprising: a housing, the housing comprising an outer portion, an inner portion, an air-flow channel, a plurality of air inlets, an air outlet, and a spoiler surface or a spoiler; wherein the air-flow channel is disposed between the outer portion and the inner portion of the housing; the air inlets are disposed on the outer portion of the housing, and the air outlet is disposed at a rear of the outer portion of the housing; the air-flow channel communicates with the air inlets and the air outlet; the spoiler surface or the spoiler is disposed on a bottom of the outer portion of the housing, a top of the inner portion of the housing, or both the bottom of the outer portion and the top of the inner portion of the housing, for extending path of the air; the length of the path of the air passing through the bottom of the outer portion of the housing is longer than that passing through the top of the inner portion of the housing, whereby producing lifting force of the inner portion of the housing and eliminating lifting force of the outer portion of the housing during the travelling of the vehicle. ### Claim 2 (depends on 1) The vehicle of claim 1, further comprising a plurality of elastic devices, wherein the outer portion and the inner portion of the housing are connected via the elastic devices. ### Claim 3 (depends on 2) The vehicle of claim 2, further comprising a plurality of magnetic devices having opposite polarities, wherein the magnetic devices are disposed on a contact surface between the elastic devices and the inner portion of the housing, or disposed between the inner portion and the outer portion. ### Claim 4 (depends on 1) The vehicle of claim 1, wherein the spoiler surface adopts a shape selected from the group consisting of a concave-convex arc, a triangle, or a trapezoid for extending the path of the air, and the spoiler surface is an integral structure. ### Claim 5 (depends on 1) The vehicle of claim 1, wherein the surface of the spoiler adopts a shape selected from the group consisting of a concave-convex arc, a triangle, or a trapezoid for extending the path of the air; and the spoiler is an independent structure. ### Claim 6 (depends on 5) The vehicle of claim 5, wherein the spoiler surface or the spoiler forms a water wave surface being symmetrical or asymmetrical in a longitudinal direction or being symmetrical or asymmetrical in both the longitudinal direction and a transverse direction, respectively. ### Claim 7 (depends on 1) The vehicle of claim 1, wherein the inner portion of the housing comprises a plurality of independent carrying spaces. ### Claim 8 (depends on 1) The vehicle of claim 1, wherein the outer portion of the housing comprises a plurality of spoilers comprising a curved outer surface and a flat inner surface, and the spoilers cover a partial or the whole inner portion of the housing; a pressure port is formed between two adjacent spoilers; and the pressure port communicates with the air-flow channel disposed between the spoilers and the inner portion of the housing. ### Claim 9 (depends on 8) The vehicle of claim 8, wherein the spoiler is disposed on the top and at two sides of the inner portion of the housing. ### Claim 10 (depends on 8) The vehicle of claim 8, wherein the spoiler is in a circular structure. ### Claim 11 (depends on 1) The vehicle of claim 1, wherein the spoiler or the spoiler surface comprises a cavity; a plurality of pressure ports are arranged on the outer surface of the spoiler or the spoiler surface; and the pressure ports communicate with the cavity. ### Claim 12 A vehicle, comprising: a housing, the housing comprising an upper portion, a bottom, and an air-flow channel; wherein the air-flow channel is disposed between the upper portion and the bottom of the housing and communicates with the atmosphere; and a lower surface of the bottom of the housing and/or an upper surface of the upper portion of the housing are provided with a spoiler or spoiler surface for extending path of the air; and the length of the path of the air passing through the spoiler on the lower part of the bottom of the housing is no less than that through the upper part of the inner portion, whereby producing lifting force of the upper portion of the housing and eliminating lifting force of the bottom of the housing during the travelling of the vehicle. ### Claim 13 (depends on 12) The vehicle of claim 12, wherein a plurality of elastic devices are disposed between the upper portion of the housing and the bottom of the housing. ### Claim 14 (depends on 13) The vehicle of claim 13, wherein magnetic devices having opposite polarities are disposed on a contact surface between the elastic devices and the upper portion of the housing and a contact surface between the elastic devices and the bottom of the housing, or disposed between the upper portion of the housing and the bottom of the housing. ### Claim 15 (depends on 12) The vehicle of claim 12, wherein a partial or the whole housing is covered with a plurality of the spoiler comprising a curved outer surface and a flat inner surface; and a pressure port is disposed between two adjacent spoilers and communicates with the air-flow channel between the spoiler and the housing. ### Claim 16 (depends on 15) The vehicle of claim 15, wherein the spoiler surface or a surface of the spoiler adopts a shape selected from the group consisting of a concave-convex arc, a triangle, or a trapezoid for extending the path of the air; and the spoiler surface is an integral structure and the spoiler is an independent structure. ### Claim 17 (depends on 15) The vehicle of claim 15, wherein the spoiler surface or the spoiler forms a water wave surface being symmetrical or asymmetrical in a longitudinal direction or being symmetrical or asymmetrical in both the longitudinal direction and a transverse direction, respectively. ### Claim 18 A vehicle, comprising a housing, wherein a spoiler surface or a spoiler is disposed on a part or the whole of a bottom of the housing, for extending path of the air, thereby eliminating lifting force during the travelling of the vehicle. ### Claim 19 (depends on 18) The vehicle of claim 18, wherein the spoiler surface adopts a shape selected from the group consisting of a concave-convex arc, a triangle, or a trapezoid for extending the path of the air, and the spoiler surface is an integral structure. ### Claim 20 (depends on 18) The vehicle of claim 18, wherein the surface of the spoiler adopts a shape selected from the group consisting of a concave-convex arc, a triangle, or a trapezoid for extending the path of the air; and the spoiler is an independent structure.
