Description

[0001] The invention relates to a motor vehicle side door according to the preamble of claim 1.

[0002] Such a motor vehicle side door is known from DE 10 2017 125 391 A1.

[0003] Another motor vehicle side door is known from DE 10 2006 037 594 A1. This motor vehicle side door has a door body section whose window opening can be closed by a retractable window pane. The window pane can be shaded by a flexible shading device designed as a roller blind. A drive system is associated with the roller blind to move it between a rest position that exposes the window pane and a shading position that shades the window pane. The roller blind is located on the inner side of the window pane facing the vehicle interior.

[0004] The object of the invention is to create a motor vehicle side door of the type mentioned above, which can be manufactured reliably with minimal effort.

[0005] This problem is solved by the features of claim 1. The solution according to the invention enables the simple pre-assembly of all functional components provided for the operation of the shading system. A person skilled in the art understands a watertight seal to be a sealing function applicable to existing motor vehicle side doors between a wet area, in which the retractable window pane runs, and a dry area, to which functional components located on the vehicle interior side are assigned. It must be prevented that water entering the vehicle interior from the outside. The double-walled module housing encloses the functional components of the shading system and the shading system's guidance system, so that the corresponding functional components are protected. The functional components can be at least largely pre-assembled in the double-walled module housing.The outer housing shell forms a partition between the wet compartment and a dry compartment of the motor vehicle side door. The dry compartment is formed, at least to a large extent, by the interior of the double-shell module housing. The solution according to the invention is particularly advantageous for a side door of the rear compartment of a passenger car. However, the motor vehicle side door according to the invention can also be used in other types of motor vehicles.

[0006] According to the invention, at least one functional component of the window pane guidance system is arranged on the outside of the outer housing shell. This allows for a further improved possibility of pre-assembly. In particular, a longitudinal guide for a support carriage of the window pane is provided as a functional component.

[0007] According to the invention, at least one functional component of the shading system is alternatively or additionally arranged on the inside of the outer housing shell. This at least one functional component of the shading system thus enables partial pre-assembly of the shading system on the outer housing shell before it is connected to the door body shell. In particular, a longitudinal guide for a support carriage of the shading system is provided as a functional component.

[0008] In one embodiment of the invention, an inner housing shell is provided facing the vehicle interior. This inner shell is joined to the outer housing shell to form a dry chamber in which the at least one shading element is arranged in its rest position. The inner housing shell and the outer housing shell form the two-part module housing.

[0009] In a further embodiment of the invention, the at least one shading element is designed as a dimensionally stable shading pane. Preferably, two shading elements are provided, one serving as the main shading element for shading a main window pane of the motor vehicle side door, and the other serving as a secondary shading element, also in the form of a dimensionally stable shading pane, for shading a secondary window of the motor vehicle side door, in particular a triangular window.

[0010] In a further embodiment of the invention, the outer housing shell and the inner housing shell are designed as plastic components. This enables the one-piece molding of functional components or holders for functional components onto the housing shells.

[0011] In a further embodiment of the invention, at least one linear guide component for the at least one shading element is integrally molded onto the inside of the outer housing shell, and another linear guide component for the window pane is integrally molded onto the outside of the outer housing shell. Advantageously, both the outer and inner housing shells are designed as thermoplastic parts, which allows for a particularly simple integral molding of the linear guide components.

[0012] In a further embodiment of the invention, the linear guide components are designed as longitudinal profiles for guiding a support carriage for the window pane and the at least one shading pane. The longitudinal profiles are preferably groove- or web-shaped, so that corresponding support carriages for the window pane on the one hand and the at least one shading pane on the other hand can be positively locked to the respective longitudinal profile in order to achieve the desired linear guidance.

[0013] In a further embodiment of the invention, an electric drive unit is mounted on the inside of the outer housing shell. The electric drive unit preferably serves to drive both the at least one shading device and the window pane. The arrangement of the electric drive unit on the inside of the outer housing shell means that the electric drive unit is located in a dry environment. This ensures particularly good operational reliability for the electric drive unit. Preferably, the electric drive unit is associated with a coupling system that enables coupling of the drive of the at least one shading device and the window pane, advantageously as described in DE 10 2021 204 275.9. The electric drive unit comprises an electric motor and a gearbox connected downstream of the electric motor.A drive transmission system, preferably a cable pull system, contributes to the transmission of the drive forces of the drive unit to corresponding support slides for the at least one shading structure and the window pane.

[0014] In a further embodiment of the invention, a cable guidance system for relocating the at least one shading element in the dry room and another cable guidance system for relocating the window pane in the wet room are provided, with both cable guidance systems being directly or indirectly coupled to the electric drive unit. Such a cable guidance system is also referred to as a cable pull system. The cable pull system comprises at least one pull cable, which can be made of metal wire rope or plastic wire rope, as well as several cable and deflection pulleys, which are rotatably mounted on the inside or outside of one of the two housing shells of the double-shell module housing.

[0015] In a further embodiment of the invention, the inner housing shell has at least one access point for mounting or adjusting functional components of the shading system when the module housing is closed. This access point is accessible from the inside of the vehicle's side door, facing the interior, and provides access to the interior of the module housing even when it is closed. To access the inner housing shell, the interior door panel must first be removed when the vehicle's side door is fully installed. The inner housing shell preferably has attachment points for securing the interior door panel to it, unless the interior door panel is directly connected to the inside of the door's body shell.

[0016] Further advantages and features of the invention will become apparent from the claims. Preferred embodiments of the invention are described below and illustrated with reference to the drawings.

[0017] A passenger car has two rear-side side doors 1 in the rear area, of which, based on the Fig. 1, Fig. 2 to Fig. Figure 3 shows the left side door 1, as viewed in the normal direction of travel of the passenger car. In its operational state, the side door 1 is pivotally hinged at the front of a B-pillar of the passenger car body. The side door 1 comprises a door body section 2, which is covered on the outside with an outer body skin and bounded on the inside facing the vehicle interior by an interior door panel 9. The door body section 2 has a window opening 3 above a vehicle sill, which can be opened and closed by a main window pane 5. Extending longitudinally to the rear of the vehicle, a triangular window 4, fitted with a fixed pane, adjoins the window opening 3.The main window pane 5, used to close the window opening 3, is movably mounted in the vehicle's vertical direction between a release position (opening the window opening 3) and a closing position (closing the window opening 3). Guide sections, not further specified, are provided in the area of ​​the door body section 2 for the lateral guidance of the window pane 5 in the vehicle's vertical direction.

[0018] In the release position, the main window pane 5 is almost completely recessed below the vehicle sill into a wet area of ​​the door-body-section 2. The wet area is, as Fig. 1, which is removable, is provided with an opening 10 towards the vehicle interior, which is limited by a circumferential edge contour of an inner skin of the door body shell 2. The opening 10 on the inner skin of the door body shell 2 is closed by an outer housing shell 7 of a two-shell module housing, wherein the outer housing shell 7 has a circumferential edge region 11 which is precisely connected to the edge contour of the opening 10 of the door body shell 2 in order to create at least a largely watertight seal of the wet area in the area of ​​the opening 10 towards the vehicle interior. The circumferential edge region 11 can additionally be provided with a seal to further improve the sealing effect in the area of ​​the edge contour of the opening 10 by the outer housing shell 7 of the module housing (see Fig. 3).

[0019] The outer housing shell 7 is designed as a one-piece plastic component and has linear profiles 14 extending vertically in the vehicle direction on its outer surface, i.e., on the outer side of the housing shell 7 facing the door skin. A support slide for the main window pane 5, which is integrally molded into the housing shell, is mounted to be linearly movable in the vehicle direction along these linear profiles 14. The main window pane 5 is therefore held on the outer side of the outer housing shell 7 and thus movable vertically in the vehicle direction.

[0020] On its inner side, the housing shell 7 has inwardly projecting, integrally molded linear profiles 13, which are provided for the linear guidance of a dimensionally stable shading structure 6. The linear profiles 13 also extend in the vertical direction of the vehicle, and are preferably formed by the externally molded linear profiles 14. A support carriage, not further specified, is provided for holding the shading structure 6. This carriage is mounted to be linearly movable along the linear profiles 13 in the vertical direction of the vehicle. The dimensionally stable shading structure 6 is designed as a semi-transparent shading panel 6, which may be provided with an electrically activatable light-protection layer, preferably a PDLC film, in order to change the degree of transparency of the shading structure 6 by appropriate electrical activation.An electric drive unit 12 is provided for moving the shading element 6 and the window pane 5. This drive unit is mounted on the inner side of the outer housing shell 7, facing the vehicle interior. The drive unit 12 includes a drive transmission system (not shown in detail) that interacts with the two support carriages for the shading element 6 and the main window pane 5 to move the shading element 6 and the window pane 5 either together or separately in the vertical direction of the vehicle. A coupling system is associated with the drive unit 12, enabling the drive transmission systems for the support carriages of the shading element 6 and the window pane 5 to be coupled or uncoupled as needed. The corresponding coupling for the drive of the shading element 6 on the one hand and the main window pane 5 on the other hand corresponds to that described in DE 10 2021 204 275.9 described coupling system, so that for further explanation reference is made to this unpublished patent application.

[0021] The module housing is completed by an inner housing shell 8, which fits precisely onto an edge of the outer housing shell 7 and can be firmly connected to it. When the module housing is assembled and closed, the inner housing shell 8 and the outer housing shell 7 enclose an interior space in which the shading element 6 and associated functional components for repositioning the shading element 6 are located. The dry space is open at the top to allow the shading element 6 to be extended and retracted.

[0022] The shading structure 6 is designed as a dimensionally stable, transparent plastic sheet. A light-blocking functional layer is applied to at least one surface of the transparent plastic sheet, which can alter the transparency of the plastic sheet through electrical activation. A PDLC film is advantageously used as the light-blocking functional layer. Alternatively, the plastic sheet itself is colored to allow partial light transmission through the shading structure 6.

[0023] As a drive transmission system for moving the main window pane 5 and the shading structure 6, a cable guide system equipped with at least one cable pulley is advantageously provided, which has cable and deflection pulleys and is coupled to the drive unit 12 in order to be driven by the drive unit 12.

[0024] In its fully assembled state, the inner housing shell 8 is covered by the door interior panel 9 towards the vehicle interior, the door interior panel 9 being attached in the area of ​​the inner door skin of the door body shell part and in the area of ​​the outer side of the inner housing shell 8 facing the vehicle interior.

[0025] A motor vehicle side door according to the Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. 9 is also intended as a rear side door for a passenger car in the same way as is the case with the motor vehicle side door according to the Fig. 1, Fig. 2 to Fig. 3 is the case. Functionally identical parts and sections of the side door according to the Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. 9 are assigned the same reference numerals with the addition of the letter a. To avoid repetition, regarding the side door, after Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. 9. In addition to the explanations regarding the side door according to the Fig. 1, Fig. 2 to Fig. 3. The differences of the side door according to the following are described below. Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. 9 in relation to the side door according to the Fig. 1, Fig. 2 to Fig. 3 received.

[0026] The side door also according to Fig. Section 4 comprises a door body section 2a, which has an outer door skin on the exterior of the vehicle body and an inner door skin on the interior side facing the vehicle interior. Both the outer and inner door skins are dimensionally stable, preferably constructed of sheet metal. A cavity is formed between the inner and outer door skins, in which a main window pane (not shown) can be moved to close or open a window opening 3a. The window opening 3a is laterally bounded by guide rails, which are provided for moving the main window pane. The door body section 2a also has a triangular window 4a, which adjoins the rear of the window opening 3a. The triangular window 4a is fitted with a fixed window pane.

[0027] A double-shell module housing according to the Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig. 9 serves firstly to hold and reposition the window pane and secondly to hold and reposition two shading structures 6a, 19. The two shading structures 6a, 19 are intended to shade the window pane 3a and the triangular window 4a from the inside when required.

[0028] One shading element 6a is a primary shading element intended to shade the main window pane 3a. The secondary shading element 19 serves to shade the triangular window 4a. Both shading elements 6a and 19 are designed as dimensionally stable, plate-shaped shading elements.

[0029] Both the main shading structure 6a and the secondary shading structure 19 are designed as transparent plastic disc components, supplemented by an electrically activated light-blocking layer, in this case a PDLC film, to modify the light transmission of the respective shading structure 6a, 19. The PDLC films are applied to the plastic disc components across their entire surface.

[0030] The main shading structure 6a is held on a support slide 15a, which is movable along longitudinal profiles 13a in the vehicle's vertical direction, which are formed on the inside in the area of ​​the outer housing shell 7a (see in particular Fig. 6 and Fig. 8).

[0031] The secondary shading structure 19 is mounted on a further support carriage 24 along inclined guide profiles 20 (see Fig. 6 and Fig. 8) held. The guide profiles 20 are also formed in one piece from the outer housing shell 7a.

[0032] The carrier carriage 24 of the secondary shading structure 19 has a web guide which is guided linearly movable in the guide profiles 20.

[0033] An electric drive unit 12a comprises an electric motor and a suitable gearbox. The drive unit 12a is coupled to a cable guide system for repositioning the main shading structure 6a and the secondary shading structure 19. Furthermore, the drive unit is also coupled to another cable guide system, which is provided for repositioning the support carriage 22 for the window pane (not shown), which is located in the wet room. The support carriage 22 is, as shown by the Fig. 7 can be relocated on the outside of the outer housing shell 7a along the longitudinal profiles 14a.

[0034] The cable guidance system for relocating the main shading structure 6a and the secondary shading structure 19 is arranged at least partially in the area of ​​the inside of the inner housing shell 8a, as shown in Fig. 7 recognizable rope guide section 23 can be removed.

[0035] The support carriage 15a for the main shading structure 6a, on the other hand, is arranged on the inside of the outer housing shell 7a at the corresponding longitudinal profiles 13a. Based on the Fig. 7 and Fig. 8 The coupling system 21, which is only indicated, serves to transmit the transmission forces of the drive unit 12a, as required, to the cable guide system for the carrier carriage 22 on the outside of the outer housing shell 7a. This cable guide system, intended for the outside and including corresponding cable and deflection pulleys, is connected by the cable guide section 25 in Fig. 7 indicated.

[0036] The drive unit 12a is mounted on a bracket 26 of the outer housing shell 7a on the inside of the housing shell 7a, at the bottom, next to the linear profiles 13a. The bracket 26 is formed, at least in part, integrally from the outer housing shell 7a.

[0037] The support carriage 15a is connected to a holding section of the main shading structure 6a, which, as Fig. 7 is removable and is assigned to the inner housing shell. The guide carriage 24 and the holding section are positively coupled to each other, so that a displacement of the carrier carriage 15a necessarily also causes a complementary displacement of the guide carriage 24 in the guide profiles 20.

[0038] The outer housing shell 7a also has a circumferential edge area 11a, which can be precisely fitted onto the edge contour of an opening (not shown) in the inner door skin of the door body section 2a to achieve a tight seal between the outer door skin and the inner door skin of the door body section 2a on the inside, i.e., towards the vehicle interior. Furthermore, the outer housing shell 7a can be connected to the inner housing shell 8a at its edges via detachable fasteners to create the two-part module housing.

[0039] The inner housing shell 8a additionally has several mounting openings 16 to 18, which are identified by the Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8 to Fig.9 are recognizable. These serve to adjust corresponding functional components for the shading structures 6a and 19 even when the module housing is already closed, so that remaining adjustment or assembly steps are also possible through these assembly openings 16 to 18 when the inner and outer housing shells 7a, 8a are already connected.

[0040] Corresponding side guides on the door body shell section 2, 2a for the window pane 5, 5a, as well as the support slide for the window pane 5, 5a, are part of the window pane guide system according to the invention. The same applies to the linear profiles 14, 14a of the outer housing shell 7, 7a.

[0041] The linear profiles 13, 13a, a carrier slide 15, 15a, the guide profiles 20, the guide slide 24 and the unspecified retaining element for the main shading structure 6a are part of the shading structure guidance system according to the invention.
