[0035] Hereinafter, a handrail assembly for a vehicle and a door assembly for a vehicle having a sliding handrail, according to embodiments of the present disclosure, will be described in detail with reference to the accompanying drawings.

[0036] like Figures 2 to 8 As shown, a door assembly 1 for a vehicle with a sliding armrest according to an embodiment of the present disclosure includes an armrest 30 for supporting a passenger's arm, the armrest being mounted on top of a lower trim panel 20 to slide in the vehicle's longitudinal direction, in which the door panel 10 is made of sheet metal to form a structure, and the lower trim panel 20 is decorated by being attached to the bottom of the door panel 10.

[0037] The door assembly 1 includes a door panel 10, such as an inner panel or an outer panel, and a door trim for decorating the outer side of the door panel 10.

[0038] Typically, the door panel 10 is a plate made of metal material to form the structure of the door assembly 1. According to embodiments of this disclosure, the door panel 10 may be an inner panel.

[0039] The door trim panel is attached to the exterior of the vehicle's interior side within the door panel 10. The door trim panel includes the portion of the door assembly 1 exposed to the interior side of the vehicle, covering the door panel 10 and various instruments and wiring mounted on the door panel 10, and is in direct contact with the passengers.

[0040] In particular, according to embodiments of the present disclosure, the door trim panel is preferably a lower trim panel 20 attached to the bottom of the door assembly 1.

[0041] The armrest 30 is mounted on top of the lower trim panel 20 and can slide in the longitudinal direction of the vehicle. Because the armrest 30 is sliding, passengers can adjust the armrest 30 to their desired position for more comfortable support of their arms or elbows.

[0042] To allow the armrest 30 to slide within the lower trim panel 20, a base 40, a slider 31, and a guide 41 are provided therein.

[0043] The base 40 is fixedly mounted on the top of the lower trim panel 20, the slider 31 is slidably mounted on the base 40, and the armrest 30 is connected to the top of the slider 31. The guide 41 is fixedly mounted on the base 40 and passes through the slider 31, and the armrest 30 is connected to the slider 31, so that the armrest 30 can slide in the lower trim panel 20.

[0044] That is, a guide groove 31a is formed in the slider 31 along the longitudinal direction of the vehicle, the guide member 41 passes through the guide groove 31a, and the guide member 41 is connected to the slider 31, so that the slider 31 slides relative to the base 40 and the guide member 41, thereby the armrest 30 slides relative to the lower trim panel 20.

[0045] The guide groove 31a has a predetermined width w3 in the longitudinal direction of the vehicle, and the guide member 41 passes through the guide groove 31a to be fixedly mounted on the lower trim panel 20, so that the slider 31 and the armrest 30 can slide in the longitudinal direction of the vehicle.

[0046] Meanwhile, in order to provide a tactile experience when passengers slide the handrail 30, a protrusion 41a can be formed on the guide 41, and an inner rail 31b can be formed in the slider 31.

[0047] A stepped groove, forming with the guide groove 31a, is formed on the slider 31, and an inner rail 31b is formed in the inner surface of the groove. The inner rail 31b has an outwardly curved portion 31ba that curves outward from the slider 31 and an inwardly curved portion 31bb that curves inward from the slider 31. These two curved portions are continuously alternately formed in the longitudinal direction of the vehicle to provide a tactile feel when the slider slides. The inner rail 31b has alternating outwardly curved portions 31ba and inwardly curved portions 31bb, and the protrusion 41a moves relative to the inner rail 31b in contact with it.

[0048] At this time, in order to ensure proper operability without lateral clearance when the slider 31 slides, the width w1 of the portion of the guide 41 with the protruding portion 41a is made larger than the width w2 of the portion of the slider 31 with the outwardly curved portion 31ba (w1 > w2), so that they overlap each other within a predetermined range. Figure 8 Part B shown in the image.

[0049] Furthermore, the radius Ra of the protruding portion 41a is formed to be smaller than the radius Rb of the outwardly curved portion 31ba.

[0050] The radius Ra of the protruding portion 41a is formed to be smaller than the radius Rb of the outwardly curved portion 31ba, such that when the slider 31 slides, the protruding portion 41a is positioned inside the outwardly curved portion 31ba. When the slider 31 slides, the protruding portion 41a can alternately contact the outwardly curved portion 31ba and the inwardly curved portion 31bb, and stops only at the portion where the outwardly curved portion 31ba is formed, so that the passenger can feel the operation during operation.

[0051] Table 1 below shows examples of the radius Ra of the protruding portion 41a, the radius Rb of the outwardly curved portion 31ba, and the amount of overlap between the protruding portion 41a and the outwardly curved portion 31ba.

[0052] Ra (unit: mm) Rb (unit: mm) Overlap (unit: mm) Operability Comparative Example 1 7.0 10.0 0.3 Left and right gaps appear Comparative Example 2 7.5 10.5 0.4 good Comparative Example 3 8.0 11.0 0.5 good Comparative Example 4 8.5 11.5 0.6 Highly operable

[0053] Table 1: Implementation methods for the radius of the protruding portion, the radius of the outwardly curved portion, and the amount of overlap between the protruding portion and the outwardly curved portion.

[0054] Therefore, it can be seen that, preferably, the radius Ra of the protruding portion 41a is 7.5 mm to 8 mm, and the radius Rb of the outwardly curved portion 31ba is 10.5 mm to 11 mm.

[0055] Furthermore, preferably, the amount of overlap between the guide 41 and the outwardly curved portion 31ba is 0.4 mm to 0.5 mm.

[0056] The protrusion 41a may be formed on the portion of the guide 41 adjacent to the front end of the guide 41.

[0057] Since the protrusion 41a is located at the front of the guide 41, a gap may be generated at the rear of the guide 41. Therefore, a contact portion 41b is formed on the guide 41. The contact portion 41b is formed such that each of the two side ends of the guide 41 contacts the inwardly curved portion 31bb of the inner rail 31b behind the protrusion 41a.

[0058] The width w2 of the portion forming the inner rail 31b is formed to be greater than the width w3 of the guide groove 31a, thereby preventing the slider 31 from separating from the guide 41.

[0059] Meanwhile, items such as umbrella U can be stored in the unused space between door panel 10 and door trim panel. Umbrella U will be used as an example of such an item to describe this exemplary embodiment.

[0060] The housing 21 is formed to have a space therein for storing the umbrella U. The housing 21 is installed between the door panel 10 and the door trim panel. In particular, since the gap between the lower trim panel 20 and the door panel 10 is large, the housing 21 is preferably installed between the lower trim panel 20 and the door panel 10.

[0061] Here, the housing 21 is mounted in the height direction of the door assembly 1, so that moisture can easily flow downward between the door panel 10 and the lower trim panel 20.

[0062] The upper end of the housing 21 is open, serving as an outlet 21a through which the umbrella U is drawn out. The sliding displacement d of the handrail 30 is formed to be greater than the diameter of the outlet 21a. Figure 6 and Figure 7 As shown, the handrail 30 has a displacement d from L0 to L1, and when the handrail 30 slides to its maximum extent backward from the vehicle ( Figure 6 As shown in L0), exit 21a is fully closed, and when the handrail 30 slides forward from the vehicle to its maximum extent ( Figure 7 As shown in L1), outlet 21a is fully open. Figure 3 It is along Figure 9 The cross-sectional view shown by line II illustrates the state in which umbrella U is stored within housing 21, and Figure 4 The image shows the handrail 30 moving forward and the umbrella U stored inside the housing 21.

[0063] A cover fastening portion 21b is formed on one side of the housing 21, which is in the form of a cut-off portion of the housing 21. Through the cover fastening portion 21b, the interior of the housing 21 has an openable structure, allowing the interior of the housing 21 to be cleaned or foreign objects to be removed as needed. Preferably, the cover fastening portion 21b is formed on the bottom of the housing 21.

[0064] A drainage section 22 for draining water is formed on the lower end of the housing 21.

[0065] The cover 23 is fixed to the housing 21.
