Description

Technical Field

[0001] The present disclosure relates to a vehicle door including a plastic film seal and a method of assembling the same. Background Art

[0002] Vehicle doors are usually made of sheet metal and have various devices arranged therein.

[0003] For example, a vehicle door is provided with devices such as a regulator for raising and lowering a door glass installed on the vehicle door, a speaker, etc. These devices are assembled together into a single module before being provided on the vehicle door, or each device is directly provided on the vehicle door. Specifically, the regulator is divided into a modular regulator in which components constituting the regulator form a single module and a non-modular regulator in which components constituting the regulator are separately and directly provided on the vehicle door.

[0004] Compared with modular lifters, the problem with non-modular lifters is that when the door trim is separated from the door, the non-modular lifter has a poor appearance and its waterproof performance deteriorates. The door trim is assembled to the door after the lifter is installed on the door. Before fitting the door trim or separating the door trim from the door for maintenance, the various components of the non-modular lifter are exposed to the outside, and the through holes through which the various components are installed to the door are also exposed, thereby reducing the appearance of the door. In addition, before the door trim is assembled to the door, a plastic film is attached to the inner panel of the door to provide a waterproof seal. Here, the plastic film has a simple planar shape. The peripheral portion of the plastic film is cut in a conforming manner to the portion of the inner panel to which the plastic film is to be attached, and then the plastic film is attached to the inner panel of the door to cover the various devices installed on the door. Since the plastic film has a simple planar shape, some peripheral portions of the plastic film may not be closely attached to the inner panel due to the portion of the device protruding toward the vehicle compartment, thereby failing to provide a waterproof seal. In other words, in the case where there is a protruding portion toward the vehicle compartment, such as the inner panel bulging inward or provided with wires, some peripheral portions of the plastic film may not be attached to the inner panel, or may be separated therefrom after being attached, thereby failing to provide a waterproof seal.

[0005] Furthermore, when the plastic film is applied to the inner panel, it is difficult to set the attachment position of the plastic film on the inner panel, so the attachment position of the plastic film may be uneven, thereby causing a decrease in waterproof performance.

[0006] The statements in this Background section merely provide background information related to the present disclosure and may not constitute prior art. Summary of the invention

[0007] The present invention provides a vehicle door including a plastic film seal and an assembly method thereof. The plastic film seal may have a three-dimensional (3D) shape that conforms to the inner shape of the vehicle door, and when the plastic film seal is attached to the vehicle door, it may facilitate setting of a reference position of the plastic film seal and improve waterproof performance.

[0008] In one aspect of the present disclosure, a vehicle door includes an outer panel, an inner panel disposed inside the outer panel, a door interior panel attached to the inner panel and finishing the inner panel, and a plastic film sealer disposed between the inner panel and the door interior panel.

[0015] The plastic film seal may comprise reinforcing ribs in the form of a grid.

[0016] The reinforcing rib may be provided at a predetermined position on the plastic film seal with a predetermined area.

[0017] The plastic film seal may include a wire receiving portion that protrudes toward the door trim and is configured to receive the wire.

[0018] The plastic film seal may include wiring apertures that allow wiring to extend therethrough.

[0019] The plastic film seal may include a first drain guide protruding toward the outside of the vehicle, the width of which increases in a downward direction so that moisture flows through the first drain guide.

[0020] The plastic film seal may include a second drainage guide disposed below the first drainage guide and configured to guide moisture to flow downward for drainage.

[0021] The plastic film seal may be made of a thermoplastic material, such as polyethylene.

[0022] The plastic film seal may be formed by vacuum forming the plastic film.

[0023] The plastic film seal may be formed into a shape that conforms to the shape of the inner panel.

[0024] The plastic film seal may include an embossed surface.

[0040] The following description is merely exemplary in nature and is not intended to limit the present disclosure, application, or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0041] When a component, device, element, or the like of the present disclosure is described as having a purpose or performing an operation, function, etc., the component, device, or element should be considered to be “configured to” satisfy the purpose or perform the operation or function.

[0042] Hereinafter, a vehicle door including a plastic film seal and an assembling method thereof will be described in detail with reference to the accompanying drawings.

[0043] According to an embodiment of the present disclosure, the vehicle door 100 may include: an inner panel 10 disposed inside an outer panel 10A of the vehicle door 100, a door interior panel 20 attached to the inner panel 10 and finishing the inner panel 10, and a plastic film seal 30 disposed between the inner panel 10 and the door interior panel 20. Specifically, the door interior panel 20 completes the inner panel 10, making it look more beautiful or more functionally complete.

[0044] The vehicle door 100 may generally be manufactured from a plurality of panels including an inner panel 10 and an outer panel 10A.

[0045] The inner panel 10 may be located at the innermost position in the vehicle width direction among the panels of the vehicle door 100 .

[0046] The inner panel 10 may have a through hole that allows various devices (e.g., a lifter and a speaker) to be disposed therein, or allows various cables (or wiring) to extend therethrough. In addition, a fastening hole that allows the door trim panel 20 to be mounted to the inner panel 10 may be provided.

[0047] A tape receiving groove 11 for receiving the adhesive tape 40 to install the plastic film seal 30 may be provided and formed in the inner panel 10. The cross section of the tape receiving groove 11 may have a predetermined depth in the vehicle outward direction. The tape receiving groove 11 may be provided in the inner panel 10 in the form of a closed curve. The tape receiving groove 11 may be formed in a predetermined area of ​​the inner panel 10, such as an area requiring watertightness.

[0048] The door trim 20 may be attached to the inner panel 10 . The door trim 20 may be a portion of the door 100 that is exposed to the inside of the vehicle (ie, the vehicle interior), and finishes the inner panel 10 .

[0049] The adhesive tape 40 may be inserted into the tape receiving groove 11. The adhesive tape 40 may be provided to the inner panel 10 along the tape receiving groove 11 and around the periphery of the area requiring watertightness. Since the tape receiving groove 11 is provided, the attachment of the adhesive tape 40 may be performed such that the adhesive tape 40 is received in the tape receiving groove 11. Therefore, when the adhesive tape 40 is attached to the inner panel 10, the tape receiving groove 11 may serve as a guide.

[0050] The tape 40 may include a butyl component.

[0051] A plastic film seal 30 may be disposed between the inner panel 10 and the door trim panel 20 to prevent moisture from moving or migrating from the inner panel 10 to the door trim panel 20 .

[0052] The plastic film seal 30 may be attached to the inner panel 10 by an adhesive tape 40 .

[0053] The plastic film seal 30 can be manufactured by vacuum forming. The plastic film seal 30 can be made into a shape that conforms to the inner panel 10 by vacuum forming. In other words, at the position where the inner panel 10 protrudes into the vehicle compartment, the plastic film seal 30 can also be configured to protrude into the vehicle compartment. This is intended to prevent such a problem: when the plastic film seal 30 is attached to the inner panel 10, the protruding part or the wiring W of the inner panel 10 may cause the plastic film seal 30 to wrinkle, or the periphery of the plastic film seal 30 is not attached to the inner panel 10. The plastic film seal 30 can be formed into a three-dimensional (3D) shape inside the mold by vacuum forming, so that at the position protruding from the inner panel 10 or the position where the cable W is located, the plastic film seal 30 can be formed into a convex shape by conforming to such a protruding feature. Therefore, the phenomenon that the plastic film seal 30 wrinkles or the peripheral portion of the plastic film seal 30 is not attached to the inner panel 10 can be avoided or prevented.

[0054] The plastic film seal 30 may be molded from a thermoplastic material such as polyethylene (PE). When the plastic film seal 30 is manufactured by vacuum forming, vacuum forming may be performed so that the surface of the plastic film seal 30 may be formed to have an embossed surface (see Figure 3 (Enlarged view at the lower left). Since the surface of the plastic film seal 30 is embossed, it is possible to prevent the adjacent plastic film seals 30 from being in close contact with each other and not being separated from each other when the plastic film seal 30 is stored. In addition, when the plastic film seal 30 is attached using the adhesive tape 40, the adhesion of the plastic film seal 30 to the adhesive tape 40 can be improved by the embossed surface.

[0055] The plastic film seal 30 may have an attachment guide 31 protruding along its periphery to receive the adhesive tape 40. The attachment guide 31 may be configured to receive or accommodate a portion of the cross section of the adhesive tape 40. The attachment guide 31 may guide a worker to align the plastic film seal 30 with the adhesive tape 40 using the attachment guide 31, thereby allowing the worker to conveniently attach the plastic film seal 30.

[0056] In addition, since the tape receiving groove 11 is formed in the inner panel 10, and the pasting guide 31 is formed along the tape receiving groove 11, the adhesive tape 40 can be located in the space formed by the pasting guide 31 and the tape receiving groove 11, as shown in FIG. Figure 4 In addition, the adhesive tape 40 can form a closed curve within the plastic film seal 30 .

[0057] In order to easily limit the attachment position of the plastic film seal 30 to the inner panel 10, a mounting reference protrusion 12 and a mounting reference hole 32 may be formed in the inner panel 10 and the plastic film seal 30, respectively. The mounting reference protrusion 12 may be provided on the inner panel 10 formed as a rigid body (e.g., a metal plate) and protrude from the surface of the inner panel 10, and the mounting reference hole 32 may be provided in the plastic film seal 30. The mounting reference protrusion 12 may be provided on the inner panel 10 in a manner protruding into the vehicle. The mounting reference hole 32 may be provided in the plastic film seal 30 so that the mounting reference protrusion 12 extends through it. In one embodiment, a plurality of mounting reference protrusions 12 may be provided on the inner panel 10, and a plurality of mounting reference holes 32 may be provided, the same number as the mounting reference protrusion 12. The mounting reference protrusion 12 may be provided at the top of the inner panel 10, and the mounting reference hole 32 may be provided at the top of the plastic film seal 30. In addition, as Figure 2 and Figure 3As shown, the mounting reference protrusion 12 may be located outside the belt receiving groove 11 of the inner panel 10, and the mounting reference hole 32 may be located outside the pasting guide 31 in the plastic film seal 30. When the plastic film seal 30 is attached to the inner panel 10 so that the mounting reference protrusion 12 extends through the mounting reference hole 32, the plastic film seal 30 may be in place even if no other parts may be additionally aligned.

[0058] A reinforcing rib 33 may be provided to allow the plastic film seal 30 to maintain a 3D shape. In the plastic film seal, the reinforcing rib 33 may be provided at a predetermined position with a predetermined area. The reinforcing rib 33 may be provided to protrude from the plastic film seal 30 in the form of a grid. Due to the grid structure, the strength of the soft plastic film seal 30 may be enhanced.

[0059] See also Figure 5 The plastic film seal 30 may have a wire receiving portion 34 configured to receive or accommodate the wire W provided on the vehicle door. The wire receiving portion 34 may protrude from the surface of the plastic film seal 30 toward the door trim 20 to receive the wire W therein.

[0060] The plastic film seal 30 may be provided with a wiring slit 35 that allows the wiring W to extend through the plastic film seal 30. Since some of the wiring W provided on the vehicle door 100 may be required to be electrically connected to the door trim panel 20, the wiring slit 35 may be provided in the plastic film seal 30 so that the wiring W extends through it. Figure 7 and Figure 8 An example is shown in each case in which a wire W extends through the plastic film seal 30 via a wire gap 35 .

[0061] The plastic film seal 30 may use a structure for guiding the flow of moisture that is inevitably introduced between the plastic film seal 30 and the inner panel 10. For example, moisture may enter between the plastic film seal 30 and the inner panel 10 through the inner belt portion of the inner panel 10. In order to guide moisture to enter between the plastic film seal 30 and the inner panel 10 in this way, the plastic film seal 30 may be provided with a first drainage guide 36 and a second drainage guide 37.

[0062] The first drainage guide 36 may be provided on the plastic film seal 30 in a manner protruding outward from the vehicle. In addition, the first drainage guide 36 may be configured such that its width increases in a downward direction so that moisture flows along the first drainage guide 36 as indicated by an arrow.

[0063] The second drainage guide 37 may be disposed below the first drainage guide 36. The second drainage guide 37 may guide the water bypassing the first drainage guide 36 to flow to the lowermost end between the inner panel 10 and the plastic film sealer 30, as indicated by an arrow.

[0064] The inner panel 10 may be provided with a drainage hole (not shown) through which the moisture that has moved to the lower portion through between the inner panel 10 and the plastic film seal 30 is discharged to the outside. In other words, the drainage hole may be formed at a portion of the inner panel 10 adjacent to the lower end of the first drainage guide 36, at a lower end of a portion of the inner panel 10 surrounded by the plastic film seal 30, etc., so that moisture is discharged from the vehicle door 100 through the drainage hole.

[0065] The plastic film seal 30 may be provided with words 38 such as "RR, RH" on which the vehicle door to which the plastic film seal 30 is applied, the installation direction of the plastic film seal 30, etc. are marked. For example, Figure 3 A plastic film seal 30 is shown for a passenger side rear door. Figure 3 In the figure, the arrow indicates that the top end in the figure can also be the top end of the car door.

[0066] Fig. 9 is a flow chart illustrating a method of assembling a vehicle door including a plastic film seal according to an embodiment of the present disclosure.

In this way, the periphery of the plastic film sealer 30 may be attached to the inner panel 10, thereby forming a watertight seal between the inner panel 10 and the plastic film sealer 30.

[0072] In addition, before performing the plastic film seal attaching step S130, the wiring W extending through the plastic film seal 30 may be extended through the plastic film seal 30. Alternatively, in the plastic film seal attaching step S130, the periphery of the plastic film seal 30 may be pasted to the inner panel 10 while the wiring W is extended through the plastic film seal 30.

[0073] The decoration installation step S140 may include: installing the door interior panel 20 on the inner panel 10. Since the door interior panel 20 is installed on the inner panel 10, the inner panel 10 can be finished. As an example of a method of installing the door interior panel 20 on the inner panel 10, the door interior panel 20 may be installed on the inner panel 10 by fitting a pin provided on the inner surface of the door interior panel 20 to a fastening hole provided in the inner panel 10.
