4 . The vehicle panel door of claim 1 ,
wherein the support member includes a stabilizer and an impact beam that are disposed in a height direction of the vehicle on the door to be spaced apart from each other.
5 . The vehicle panel door of claim 4 ,
wherein the reinforcement member includes a hinge upper reinforcer to which an upper hinge connecting the door to a body of the vehicle is fastened and to which a front end portion of the stabilizer is coupled, and
wherein the joint members include an upper hinge joint surrounding the front end portion of the stabilizer.
6 . The vehicle panel door of claim 5 ,
wherein the reinforcement member further includes a hinge reinforcer which is positioned on a lower portion of the hinge upper reinforcer, to which a lower hinge that hinge-connects the door to the body of the vehicle is fastened under the upper hinge, and to which a front end portion of the impact beam is coupled, and
wherein the joint members further include a lower hinge joint surrounding the front end portion of the impact beam.
7 . The vehicle panel door of claim 4 ,
wherein the reinforcement member further includes a latch reinforcer on which a latch is provided in a rear end portion of the door and to which a rear end portion of the stabilizer is coupled, and
wherein the joint members further include a latch upper joint surrounding the rear end portion of the stabilizer.
8 . The vehicle panel door of claim 7 ,
wherein the reinforcement member further includes a latch lower reinforcer to which a rear end portion of the impact beam is coupled under the latch reinforcer, and
wherein the joint members further include a latch lower joint surrounding the rear end portion of the impact beam.
9 . The vehicle panel door of claim 1 , wherein an external edge portion of the joint members is joined to the reinforcement member.
10 . The vehicle panel door of claim 1 , wherein an external edge portion of the reinforcement member is joined to the internal panel or the external panel.
11 . The vehicle panel door of claim 1 , wherein the joint members and the support member are joined to each other using an adhesive.
12 . The vehicle panel door of claim 1 , wherein the joint members and the support member are joined to each other by CO 2 welding.
13 . The vehicle panel door of claim 1 ,
wherein a flange portion which is formed to extend outward to be joined to the reinforcement member and a seating portion on which the reinforcement is accommodated are formed on the auxiliary bracket.
14 . The vehicle panel door of claim 1 ,
wherein one of the external panel and the internal panel is made of plastic material, and another thereof is made of metal material.
15 . The vehicle panel door of claim 14 ,
wherein the external panel is made of the plastic material, and the internal panel is made of the metal material.
16 . The vehicle panel door of claim 1 , wherein the support member is joined to the reinforcement member, and thus a structure formed of the support member and the reinforcement member is in a shape of a quadrangle.
17 . The vehicle panel door of claim 16 , wherein the structure is formed in a shape of a rectangle.
18 . A vehicle including a rigidity improved the vehicle panel door of claim 1 .
19 . The vehicle of claim 18 ,
wherein the support member includes a stabilizer and an impact beam that are disposed in a height direction of the vehicle on the door to be spaced from each other, and
where a rear end portion of the stabilizer is joined by a latch upper joint by surrounding thereof, and a front end portion of the impact beam is joined by a lower hinge joint at a lower hinge that connects the door to a body of the vehicle, and a rear end portion of the impact beam is joined by a latch lower joint, respectively.
