    DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

    [0015] Hereinafter, an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

    [0016] As showed in FIGS. 1-3, a gas steel cylinder structure for cars comprises:

    [0017] a gas steel cylinder (1) having an inner cylinder body (11), an outer cylinder body (12), a first chamber (13) disposed in a middle of the inner cylinder body (11), and a second chamber (14) between the inner cylinder body (11) and the outer cylinder body (12), wherein the inner cylinder body (11) is integrally forged with the outer cylinder body (12) and provided with a through hole (111) for communicating the first chamber (13) with the second chamber (14);

    [0018] an upper lid (2) correspondingly sealed on the gas steel cylinder (1), wherein the upper lid (2) is provided with a perforation (21) in the middle thereof for the inner cylinder body (11) to penetrate therethrough; and

    [0019] a top lid (3) having an inserting section (31) relative to the perforation (21) of the upper lid (2) for penetrating the perforation (21) and correspondingly locking on the inner cylinder body (11).

    [0020] In use of the gas steel cylinder structure for cars as showed in FIGS. 1-3, the gas steel cylinder (1) is preferentially manufactured by aluminum, magnesium or aluminum-magnesium alloy. An opening of the outer cylinder body (12) of the gas steel cylinder (1) is provided with a first bonding portion (121), and an opening of the inner cylinder body (11) is provided with a second bonding portion (112). An inner margin of the upper lid (2) is provided with a first locking portion (22) for correspondingly locking on the first bonding portion (121), and the first locking portion (22) of the upper lid (2) is provided with a first sealing pad (4) relative to the first bonding portion (121) of the outer cylinder body (12) of the gas steel cylinder (1). In assembling the gas steel cylinder structure for cars, the inner cylinder body (11) penetrates into the perforation (21) of the upper lid (2) when the upper lid (2) is locked on the outer cylinder body (12) of the gas steel cylinder (1), and then the inserting section (31) of the top lid (3) is correspondingly locked on the second bonding portion (112) of the inner cylinder body (11) for covering on the upper lid (2). The inserting section (31) is further provided with a second locking portion (311) for correspondingly locking on the second bonding portion (112) of the inner cylinder body (11) so as to bond the top lid (3) to the gas steel cylinder (1). Moreover, the second locking portion (311) of the inserting section (31) of the top lid (3) is provided with a second sealing pad (5) relative to the second bonding portion (112) of the inner cylinder body (11) of the gas steel cylinder (1), and the inserting section (31) is provided with a third sealing pad (6) relative to the perforation (21) of the upper lid (2). In such a case, the first sealing pad (4), the second sealing pad (5) and the third sealing pad (6) can prevent gas leaking out of the gas steel cylinder (1).

    [0021] The top lid (3) is further provided with a plurality of valve mechanisms (not shown in FIGS. 1-3) for inputting and outputting gas. Accordingly, the whole gas steel cylinder structure has structural strength and may not be subject to air leaks in use.

    [0022] Compared with the technique available now, the present invention has the following advantages:

    [0023] 1. The inner cylinder body is integrally forged with the outer cylinder body, so the gas steel cylinder structure of the present invention has structural strength and no air leaks in use, which increases the usage security of the gas vehicles.

    [0024] 2. The design of the plural sealing pads can prevent gas leaking out of the gas steel cylinder structure which increases the usage security of the gas vehicles.

    [0025] 3. The inner cylinder body is integrally forged with the outer cylinder body, so the gas steel cylinder structure of the present invention achieves efficacy of simplified manufacturing procedures and cost reduction.
