Description

Technology Field

[0001] The present invention relates to a reinforcing member assembly installed inside a vehicle door to reinforce the rigidity of the door, and more specifically, to a reinforcing member assembly for a door capable of storing items, wherein the interior is formed in a cylindrical shape and fixed at both ends inside the door. Background Technology

[0003] Vehicle bodies are typically manufactured using sheet metal.

[0004] For example, the door of the above vehicle has an inner panel and an outer panel (110) joined together to form the basic shape of the door.

[0005] In addition, to reinforce the strength of the door, the inner panel or the outer panel (110) is provided with a reinforcing member (121) having a bent cross-sectional structure so as to improve performance against side collisions. FIG. 1 illustrates an example in which the outer panel (110) is provided with a reinforcing member (121).

[0006] However, the reinforcing member (121) is formed with an open cross-section structure as described in I-I, so the torsional rigidity is weak, and there is a limit to increasing the strength of the door.

[0007] In addition, since the reinforcing member (121) has an open cross-section, the reinforcing member (121) only has the function of reinforcing the rigidity of the door, and items could not be stored using the reinforcing member (121). Since the reinforcing member (121) has an open cross-section, when items are stored using the reinforcing member (121), the stored items fall out between the inner panel and the outer panel (110), making it impossible to pull them out, so items could not be stored using the reinforcing member (121).

[0008] This entails the problem of not being able to efficiently utilize the interior space of the aforementioned vehicle. Prior art literature

Specific details for implementing the invention

[0035] A reinforcing member assembly for a door capable of storing articles according to the present invention will be described in detail below with reference to the attached drawings.

[0037] The reinforcing member assembly (20) of a door capable of storing an item according to the present invention comprises a beam pipe (21) formed in a cylindrical shape with a closed cross-section and arranged in the longitudinal direction of the vehicle on a door panel (10), brackets (22) (23) positioned at each end of the beam pipe (21) to fasten both ends of the beam pipe (21) to the door panel (10), and a connector (24) that penetrates the panel (10) and is fitted into one end of the beam pipe (21), and an item (U) is stored inside the beam pipe (21) through the connector (24).

[0039] The beam pipe (21) is formed in a cylindrical shape with a closed cross-section. Since the beam pipe (21) is formed in a cylindrical shape, even if an item such as an umbrella (U) is stored inside the beam pipe (21), it does not fall into the interior space of the door and can be pulled out.

[0040] The beam pipe (21) has brackets (22) and (23) attached to each end, and the beam pipe (21) is attached to the panel (10) of the door by being attached to the brackets (22) and (23). That is, the front and rear ends of the beam pipe (21) are attached to the front bracket (22) and rear bracket (23), respectively, which are attached to the panel (10), thereby having a structure in which the beam pipe (21) is attached to the panel (10).

[0041] Here, the bracket (22)(23) can be fastened to the outer panel (10) of the door.

[0042] The connector (24) is fitted into one end of the beam pipe (21). The connector (24) penetrates the panel (10) and is fitted into the beam pipe (21), and an item such as the umbrella (U) is stored or pulled out through the connector (24). In particular, the connector (24) is fitted into one end of the beam pipe (21) that is spaced apart from the part where the door is hinge-connected to the vehicle body.

[0043] Inside the beam pipe (21), a return spring (26) and a support (27) are provided to facilitate the extraction of the item (U) by means of elastic force when the item (U) is extracted.

[0044] The support member (27) is slidably installed inside the beam pipe (21). It is formed in the shape of a plate and contacts the end of the item (U) stored inside the beam pipe (21).

[0045] In order for the support member (27) to slide easily inside the beam pipe (21), a guide groove (21a) of a predetermined length is formed inside the beam pipe (21), and a guide (27a) is formed on the support member (27).

[0046] The guide groove (21a) is formed on the inner surface of the beam pipe (21) at a predetermined depth along the axial direction of the beam pipe (21). The guide groove (21a) is formed at intervals along the circumference of the beam pipe (21) in the cross section of the beam pipe (21). Preferably, the guide groove (21a) is formed at the top and bottom of the cross section of the beam pipe (21), respectively. Since the guide groove (21a) is formed for a predetermined length along the axial direction of the beam pipe (21), the support member (27) can slide in the section where the guide groove (21a) is formed.

[0047] The depth of the guide groove (21a) can be formed to be 40% to 60% of the thickness of the beam pipe (21). For example, if the thickness of the beam pipe (21) is 2mm, the depth of the guide groove (21a) can be 1mm.

[0048] A guide (27a) is formed to protrude from the circumference of the support member (27) toward the guide groove (21a). As the guide (27a) is received and contacts the guide groove (21a), the support member (27) can slide stably while being guided inside the beam pipe (21).

[0049] In particular, the end of the guide (27a) is made to have a round shape (see FIG. 4). That is, the end of the guide (27a) can be formed in a semicircular shape with radius R.

[0050] Meanwhile, the width (W) of the above guide (27a) B ) is the width (W) of the support (27) A Make it approximately 1 / 4 of ).

[0051] In addition, a gap (c) is formed between the perimeter of the support (27) and the inner surface of the beam pipe (21) so that when the support (27) slides, the perimeter of the support (27) and the inner surface of the beam pipe (21) do not interfere with each other.

[0052] The return spring (26) is positioned between the other end of the beam pipe (21) and the support (27), and by connecting both ends, it elastically supports the support (27) toward the direction where the connector (24) is located. Since the return spring (26) elastically supports the support (27) toward the connector (24), the support (27) can push out the item (U) stored inside the beam pipe (21) so that it can be easily pulled out (see FIG. 5).

[0053] The guide groove (21a) is positioned adjacent to the welded portion of the beam pipe (21) to make the beam pipe (21) a closed cross-section. The beam pipe (21) is formed by processing a steel plate into a circular shape and then welding it to form a tubular structure. The welded portion (W) is positioned on the cross-section of the beam pipe (21) so as to be located on the inner side of the vehicle rather than at the position (G) of the guide groove (21a), and within a certain distance from the guide groove (21a).

[0054] In particular, it is preferable that the welded portion (W) be located on the inner side of the vehicle rather than the guide groove (21a).

[0055] The cross-sectional structure of the beam pipe (21) indicated by line II-II in FIG. 1 is illustrated, and in the cross-section of the beam pipe (21), the welded portion (W) is located on the opposite side of the direction in which the impact force (F) caused by a side collision is input relative to the guide groove (21a), that is, on the inner side of the vehicle. This prevents the beam pipe (21) from breaking during a side collision.

[0056] Meanwhile, it is preferable that the guide groove (21a) be formed at a location spaced apart from the area where the impact force is input during a side collision (see FIG. 6). The side collision performance of the vehicle is tested by colliding the barrier (B) with the side of the vehicle. The area where the barrier (B) collides is a location where the probability of an impact force being input due to a side collision is high, and the guide groove (21a) is formed to avoid this area.

[0057] The beam pipe (21) is positioned at an angle for drainage. That is, the beam pipe (21) is installed at an angle so that it becomes lower as it moves away from the part where the door is hinge-connected to the vehicle body. For example, the beam pipe (21) is installed so that it becomes lower as it moves toward the rear of the vehicle. Accordingly, moisture inside the beam pipe (21) moves toward the rear of the vehicle.

[0058] In addition, for drainage, a drain hole (24c) is formed in the connector (24) to collect moisture from the beam pipe (21) and drain it into the interior of the door through the drain hole (24c).

[0059] In addition, by forming a drain hole (10a) below the drain hole (24c) in the panel (10) of the door, moisture drained into the interior of the door through the drain hole (24c) is discharged to the outside through the drain hole (10a).

[0061] The holder (25) is coupled to the connector (24) to close the connector (24), thereby preventing the item (U) stored inside the beam pipe (21) from being unintentionally withdrawn.

[0062] The holder (25) has screw threads (24a) and (25a) formed on the inner surface of the connector (24) and the outer surface of the holder (25), respectively, so that the holder (25) can be screw-coupled to the connector (24). Accordingly, when the item (U) is inserted or removed from the beam pipe (21), the holder (25) is separated from the connector (24), and when the item (U) is stored, it is connected to the connector (24), thereby preventing the item (U) from being removed from the beam pipe (21).

[0063] Meanwhile, in order to prevent the holder (25) from being lost or falling to the ground when the holder (25) is separated from the connector (24), the holder (25) and the connector (24) are connected by a cable (28). By connecting both ends of the cable (28) to the connector (24) and the holder (25), respectively, even if the holder (25) is separated from the connector (24), it can be prevented from being lost or falling to the ground because it remains connected to the connector (24). A cable mount hole (24b) may be formed in the connector (24) to connect the cable (28).

[0065] FIG. 9 illustrates the process of storing an article (U) inside a reinforcing member assembly (20) according to the present invention. Here, the case of storing an umbrella (U) will be described.

[0066] To store the umbrella (U), the holder (25) is separated from the connector (24).

[0067] Afterwards, when the connector (24) is opened, the umbrella (U) is inserted into the interior of the beam pipe (21) through the connector (24), and the umbrella (U) is stored inside the beam pipe (21).

[0068] Finally, by connecting the holder (25) to the connector (24), the umbrella (U) is prevented from coming off.

[0069] FIG. 10 illustrates the process of withdrawing an item (U) from the reinforcing member assembly (20).

[0070] First, the holder (25) is separated from the connector (24).

[0071] Subsequently, when the connector (24) is opened, a part of the item, i.e., the umbrella (U), is exposed to the outside by the elastic force of the return spring (26). When a part of the umbrella (U) is exposed in this way, the exposed part is pulled to withdraw the umbrella (U) from the beam pipe (21).

[0072] When the withdrawal is complete, the holder (25) is reattached to the connector (24). Explanation of the symbols
