Description

Technical Field

[0001] The present invention relates to a side door of a motor vehicle, comprising a door body-in-white body component having a window opening, a window sheet for closing and opening the window opening, and at least one shielding structure associated with the window sheet on the inner side facing the vehicle interior space and movably supported relative to the door body-in-white body component between a standby position (or original position, Ruhestellung) located below the window opening and at least one shielding position that at least partially covers the window opening, and a window sheet guiding system for displacing the window sheet between the closed position and the open position, and a shielding structure guiding system for displacing the at least one shielding structure between the standby position and the shielding position. Background Technology

[0002] Such a motor vehicle side door is known from DE 10 2006 037 594 A1. The motor vehicle side door has a door-white body component, and its window opening can be closed via a retractable window slat. The window slat can be concealed via a flexible concealing structure implemented as a roller blind track. A drive system is associated with the roller blind track to shift the track between an open, unopened position and a concealed position. The roller blind track is associated with the window slat on the inner side facing the vehicle interior space. Summary of the Invention

[0003] The objective of this invention is to create a motor vehicle side door of the type described above, which can be reliably manufactured with minimal operational costs.

[0004] This task is solved by providing a double-shell modular housing for accommodating the at least one shielding structure and the shielding structure guiding system, having an outer shell that is watertightly sealed to the inside of the door body-in-white component when a wet space is formed on the side of the door body-in-white component pointing outward from the inside, and the window sheet is arranged in the wet space in its open position. According to the solution of the invention, all functional components pre-assembled as a functional setting for the shielding structure are realized in a simple manner. Those skilled in the art will understand a watertight seal as a sealing function applicable to existing motor vehicle side doors between a wet space and a dry space, in which a lowerable window sheet operates, and functional components positioned on the vehicle interior space side are allocated to the dry space. Water seepage from the outside into the vehicle interior must be prevented. The double-shell modular housing surrounds the functional components of the shielding structure and the shielding structure guiding system, thus protecting the corresponding functional components. The functional components can be pre-assembled, at least largely, entirely within the double-shell modular housing. The outer housing forms a partition wall between the wet and dry spaces of the vehicle side door. The dry space is formed, at least largely, by the interior of the double-shell modular housing. The solution according to the invention is particularly advantageous for side doors in the rear seat area of ​​passenger cars. However, the vehicle side door according to the invention can also be used in other types of vehicles.

[0005] In the design of this invention, at least one functional component of the window sheet guiding system is arranged on the outer side of the outer housing. This allows for further improvements in pre-assembly. In particular, a longitudinal guide for the load-bearing slider of the window sheet is provided as a functional component.

[0006] In another embodiment of the invention, at least one functional component of the shielding structure guiding system is arranged inside the outer housing. Therefore, at least one functional component of the shielding structure guiding system can be pre-installed in the outer housing before it is connected to the door body-in-white components. In particular, as a functional component, a longitudinal guide portion for the support slider of the shielding structure is provided.

[0007] In another embodiment of the invention, an inner housing is positioned within the vehicle's interior space. This inner housing, together with the outer housing, forms a dry space in which at least one shielding structure is arranged in its standby position. The inner and outer housings together form a double-shell modular housing.

[0008] In another embodiment of the invention, the at least one shielding structure is constructed as a shape-stable shielding sheet. Preferably, two shielding structures are provided, one of which serves as the main shielding structure for shielding the main window sheet of the vehicle side door, and the other shielding structure serves as the auxiliary shielding structure, also in the form of a shape-stable shielding sheet, for shielding the auxiliary window of the vehicle side door, especially the triangular window.

[0009] In another embodiment of the invention, the outer housing and the inner housing are designed as plastic components. This allows functional components or retaining parts for functional components to be molded onto the housing in a single piece.

[0010] In another embodiment of the invention, at least one linear guide member for the at least one shielding structure is molded in one piece inside the outer housing shell, and another linear guide member for the window sheet is molded in one piece outside the outer housing shell. Advantageously, both the outer and inner housing shells are designed as thermoplastic components, thereby enabling the one-piece molding of the linear guide members in a particularly simple manner.

[0011] In another embodiment of the invention, the linear guide member is implemented as a longitudinal profile portion for guiding the load-bearing sliders for the window sheet and at least one shielding sheet, respectively. The longitudinal profile portion is preferably implemented as a groove or tab shape (or a web shape, i.e., stegförmig), so that the corresponding load-bearing sliders for both the window sheet and at least one shielding sheet can be form-fitted and supported at their respective longitudinal profile portions to achieve the desired linear guidance.

[0012] In another embodiment of the invention, the electric drive unit is mounted inside the outer housing. Preferably, the electric drive unit is used not only to drive the at least one shielding structure but also to drive the window sheet. The arrangement of the electric drive unit inside the outer housing means that it is housed in a dry space. This ensures particularly good functional safety for the electric drive unit. Preferably, the electric drive unit is associated with a coupling system that enables the coupling of the drive of the window sheet to the at least one shielding structure, advantageously as described in DE 10 2021 204 275.9. The electric drive unit includes an electric motor and a gearbox subsequently connected to the motor. A drive transmission system, preferably a drawstring system, facilitates the transmission of the driving force of the drive unit to the corresponding load-bearing sliders for the at least one shielding structure and the window sheet.

[0013] In another embodiment of the invention, a rope guiding system is provided for moving at least one shielding structure in the drying space and another rope guiding system is provided for moving window sheets in the wet space, wherein both rope guiding systems are directly or indirectly coupled to the electric drive unit. The corresponding rope guiding system is also referred to as a pull rope system. The pull rope system includes at least one pull rope, which can be implemented as a metal wire rope or a plastic wire rope, and multiple ropes and deflection rollers rotatably supported on the inner or outer side of one of the two shells of the double-shell module housing.

[0014] In another embodiment of the invention, the inner housing has at least one mounting through-hole, which is configured to allow the installation or adjustment of functional components of the shielding structure guidance system when the module housing is closed. At least one mounting through-hole in the inner housing can be accessed from the inside of the vehicle side door facing the vehicle interior space, and can also access the interior of the module housing even when it is closed. To access the inner housing, the door trim must first be removed after the vehicle side door is fully installed. The inner housing preferably has fastening points to secure the door trim to the inner housing, provided that the door trim is not directly connected to the inside of the door body-in-white components.

Detailed Implementation

[0017] The passenger vehicle has two rear-seat side doors 1 in the rear seat area, wherein - viewed from the normal driving direction of the passenger vehicle - the left door 1 is provided with Figures 1 to 3 As shown. In the ready-to-operate installation state, the side door 1 is swayably attached to the B-pillar of the passenger car body at the front. The side door 1 has a door body-in-white component 2, which has a body skin on the outer side and is restricted on the inner side facing the vehicle interior space by a door interior component 9 facing the vehicle interior space. The door body-in-white component 2 has a window opening 3 above the vehicle window sill (or vehicle window waist, i.e., Fahrzeugbrüstung), which can be closed and opened by the main window sheet 5. A triangular window 4 is connected rearward in the longitudinal direction of the vehicle to the window opening 3, which has a fixed window sheet. The main window sheet 5 for closing the window opening 3 is movably supported in the vehicle height direction between the open position of the window opening 3 and the closed position of the window opening 3. In the area of ​​the door body-in-white component 2, a guide section (not shown in detail) is provided for lateral guidance of the window sheet 5 in the vehicle height direction.

[0018] In the open position, the main window sheet 5 descends almost entirely below the vehicle window sill into the wet space of the door body-in-white component 2. (As from...) Figure 1 It can be seen that the wet space has an opening 10 facing the vehicle interior space, which is limited by the surrounding edge contour of the inner skin of the door body-in-white component 2. The opening 10 at the inner skin of the door body-in-white component 2 is closed by the outer shell 7 of the double-shell module housing, wherein the outer shell 7 has a surrounding edge region 11 that precisely matches the edge contour of the opening 10 of the door body-in-white component 2, so as to cause the wet space to be at least largely watertight in the area of ​​the opening 10 facing the vehicle interior space. The surrounding edge contour 11 may be additionally provided with a seal to further improve the sealing effect of the outer shell 7 of the module housing in the edge contour region of the opening 10 (see Figure 3 ).

[0019] The outer housing 7 is designed as a one-piece plastic component, and on its outer side, i.e., on the outer side of the housing 7 facing the door skin, there is a linear profile 14 extending in the vehicle height direction. Along these linear profiles 14, which are one-piece molded into the housing, a support slider (not shown in detail) for the main window sheet 5 is linearly and movably supported in the vehicle height direction. Therefore, the main window sheet 5 is movably held in the housing 7 on the outer side of the outer housing 7 in the vehicle height direction.

[0020] On the inner side, the housing 7 has an inwardly protruding, one-piece molded linear profile 13, which is provided for linearly guiding the shape-stabilized shielding structure 6. The linear profile 13 also extends in the vehicle height direction, and is preferably formed inevitably by the external molding (or inward molding) of the outer linear profile 14. To hold the shielding structure 6, a support slider (not shown in detail) is provided, which can be linearly supported along the linear profile 13 in the vehicle height direction. The shape-stabilized shielding structure 6 is designed as a partially transparent shielding plate 6, which may have an electrically activated light-blocking functional layer, preferably a PDLC film, so that the transparency of the shielding structure 6 can be changed by corresponding electrical activation. An electric drive unit 12 is provided for moving the shielding structure 6 and the window sheet 5, which is mounted on the inner side of the outer housing 7 facing the vehicle interior space. The drive unit 12 has a drive transmission system, not shown in detail, that interacts with two carrier sliders for the shielding structure 6 and the main window sheet 5 to displace the shielding structure 6 and the window sheet 5 together or separately in the vehicle height direction. A coupling system is associated with the drive unit 12, which can couple or decouple the drive transmission system for the carrier sliders of the window sheet 5 and the shielding structure 6 as needed. The corresponding coupling for driving the shielding structure 6 on one hand and the main window sheet 5 on the other corresponds to the coupling system described in DE 10 2021 204 275.9, for further explanation supplemented by reference to that unpublished patent application.

[0021] The module housing is completed by an inner housing shell 8, which can be precisely fitted onto the edge of the outer housing shell 7 and securely connected to it. In the assembled, closed state, the inner housing shell 8 and the outer housing shell 7 define the internal space, within which the shielding structure 6 and related functional components for moving the shielding structure 6 are arranged. The drying space is open to the top, allowing the shielding structure 6 to be driven in and out.

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

[0023] As a drive transmission system for shifting the main window sheet 5 and the shielding structure 6, a rope guiding system with at least one pull rope device is advantageously provided. This rope guiding system has a rope and a deflection roller and is connected to the drive unit 12 so as to be driven by the drive unit 12.

[0024] In the ready-to-operate installation state, the inner housing 8 is covered by the door trim 9 facing the vehicle interior space, wherein the door trim 9 is fastened to the door inner skin area of ​​the door body white body component and to the outer side of the inner housing 8 facing the vehicle interior space.

[0025] according to Figures 4 to 9 The vehicle side door is also configured as a rear seat side door for passenger cars, in a manner similar to that of... Figures 1 to 3 The same applies to the side doors of motor vehicles. According to Figures 4 to 9 The same components and sections with the same function as the side doors are marked with the same reference numerals when the letter 'a' is added. To avoid repetition, regarding... Figures 4 to 9 The side door is a supplementary reference to the information provided. Figures 1 to 3 The implementation of the side door. According to... Figures 4 to 9 Compared to the side door Figures 1 to 3 The differences in the side doors will be explained below.

[0026] according to Figure 4 The side door also has a door body-in-white component 2a, which has an outer door skin on the outer side of the body and an inner door skin on the inner side facing the vehicle interior. Both the outer and inner door skins are shape-stable, preferably constructed of sheet metal. A cavity exists between the inner and outer door skins, in which a main window sheet (not shown) can be moved to close or open the window opening 3a. The window openings 3a are laterally restricted by guide rails provided for the movement of the main window sheet. The door body-in-white component 2a also has a triangular window 4a, which is adjacent to the window opening 3a on the rear side. The triangular window 4a has a fixed window sheet.

[0027] according to Figures 4 to 9 The double-shell module housing serves two purposes: on one hand, it holds and shifts the window sheet, and on the other hand, it holds and shifts two shielding structures 6a and 19. The two shielding structures 6a and 19 are configured to shield the window sheet 3a and the triangular window 4a from the inside as needed.

[0028] One of the shielding structures, 6a, is the primary shielding structure, which is used to shield the main window sheet 3a. The secondary shielding structure 19 is used to shield the triangular window 4a. Both shielding structures 6a and 19 are designed as shape-stable plate-shaped shielding structures.

[0029] Here, both the main shielding structure 6a and the auxiliary shielding structure 19 are implemented as transparent plastic sheet components, supplemented by an electrically activated light-blocking functional layer of a PDLC film to alter the light transmittance of the respective shielding structures 6a and 19. The PDLC film is applied surface-mounted onto the plastic sheet component.

[0030] The main shielding structure 6a is held at the carrier slider 15a, which can travel along the longitudinal profile 13a in the vehicle height direction, the longitudinal profile being molded on the inner side in the outer housing shell 7a region (see especially). Figure 6 and 8 ).

[0031] The auxiliary shielding structure 19 is held on another carrier slider 24 by the guide contour portion 20 extending obliquely along the direction (see Figure 6 and 8 The guide contour section 20 is also formed in one piece from the outer shell 7a.

[0032] The supporting slider 24 of the auxiliary shielding structure 19 has a tab guide portion, which can be linearly and movablely guided in the guide contour portion 20.

[0033] The electric drive unit 12a has an electric motor and a suitable gearbox. The drive unit 12a is coupled to a rope guide system for shifting the main shielding structure 6a and the auxiliary shielding structure 19. Furthermore, the drive unit is also coupled to another rope guide system configured for shifting a load-bearing slider 22 (not shown) of a window sheet arranged in a wet space. (As can be achieved by means of...) Figure 7 It can be seen that the bearing slider 22 can be moved along the longitudinal contour portion 14a outside the outer shell 7a.

[0034] The rope guidance system for the displacement of the main shielding structure 6a and the auxiliary shielding structure 19 is at least partially arranged in the inner region of the internal housing shell 8a, such as from... Figure 7 As can be seen in the visible rope guidance section 23.

[0035] Conversely, the supporting slider 15a for the main shielding structure 6a is arranged on the inner side of the outer housing 7a at the corresponding longitudinal profile 13a. Only by means of... Figure 7 and Figure 8The coupling system 21, as shown, is used to drive the power transmission of the drive unit 12a to a rope guiding system on the outer side of the outer housing 7a, transmitting the power as needed. This rope guiding system, with corresponding ropes and deflection rollers, is located on the outer side by the rope guiding section 25. Figure 7 The Chinese side indicated that...

[0036] The drive unit 12a is disposed at the holding portion 26 of the outer housing 7a, below the inner side of the housing 7a, next to the linear profile portion 13a. The holding portion 26 is formed in one piece from the outer housing 7a, at least in sections.

[0037] The supporting slider 15a is connected to the retaining section of the main shielding structure 6a, from... Figure 7 It can be seen that the retaining section is associated with the internal housing. The guide slider 24 and the retaining section are coupled to each other in a forced guiding manner, so that the displacement of the carrying slider 15a will inevitably cause a supplementary displacement of the guide slider 24 in the guide contour section 20.

[0038] The outer housing 7a also has a surrounding edge region 11a, which can be precisely fitted onto the edge contour of the undisplayed opening of the inner door skin of the door body-in-white component 2a to achieve a tight inward seal between the outer and inner door skins of the door body-in-white component 2a, i.e., towards the vehicle interior space. Furthermore, the outer housing 7a can be connected to the inner housing 8a on the edge side via a releasable connector, thus creating a double-shell modular housing.

[0039] The internal housing 8a additionally has a plurality of mounting openings 16 to 18, which are achieved by means of... Figures 4 to 9 As can be seen, these functional components used for adjusting the corresponding structures 6a and 19 can be adjusted even when the module housing is closed, so that the remaining adjustment or installation steps can be carried out through these mounting openings 16 to 18 even when the inner and outer housing shells 7a and 8a are already connected to each other.

[0040] The corresponding lateral guide portions at the door body parts 2 and 2a for the window sheets 5 and 5a, as well as the load-bearing sliders for the window sheets 5 and 5a, belong to the window sheet guiding system in the sense of this invention. The same applies to the linear contour portions 14 and 14a of the outer housing shells 7 and 7a.

[0041] The linear contour portions 13, 13a, the carrying sliders 15, 15a, the guide contour portion 20, the guide slider 24, and the retaining element (not shown in detail) for the main shielding structure 6a belong to the shielding structure guiding system in the sense of the present invention.
