Description

[0001]
BACKGROUND OF THE INVENTION
The present invention includes a frame front member, a frame rear member, two frame side members, and a frame corner member that couples the frame side member to the frame front member and the frame rear member, and surrounds the roof opening. A slider guided by the frame side member and coupled to the front and / or rear fixing members or hooks of the folding roof; and a slider for selectively opening and closing the folding roof from the front and / or rear or from the front and / or rear An electric drive cable guided by a roof cross bar for driving the vehicle roof.
[0002]
[Prior art]
A folding roof of this kind which is actuated from the front and / or the rear is known from German Patent Publication No. 4033675. This foldable roof has two electric motors that are essentially juxtaposed in common with the frame rear member for driving to both ends and actuate a drive cable that drives a slider to displace the shielding sheet of the vehicle roof. The drive cable extends into a guide rail juxtaposed in a horizontal plane in the range of the frame side member and in the range of the frame front member and the frame rear member.
[0003]
[Problems to be solved by the invention]
This structure leads to an increase in material costs and assembly costs. Furthermore, when the folding roof is closed, only one of the drive cable pairs is always subjected to a tensile load while the other cable pair is subjected to a compressive load.
An object of the present invention is to provide a folding roof for a vehicle that can solve the problems of the prior art.
[0004]
The problem of the present invention is that it can be manufactured with as little component and assembly costs as possible, ensuring that the ends of the folding roof are displaced simultaneously and that a tensile load is always applied to the drive cable of the drive when the folding roof is closed. The object is to create a folding roof of the kind described in the premise of claim 1.
[0005]
[Means for Solving the Problems]
This problem is solved by the features of claim 1. Advantageous embodiments of the invention are indicated in the dependent claims. Moreover, the said subject is also solved by the characteristic of Claim 5.
Therefore, unlike the prior art picked up at the introduction section, the end surface of the roof frame is provided with an electric motor for opening and closing the folding roof via a pair of drive cables operated in the opposite directions. By providing the drive motors in such a positional separation, opening and closing operations can be simultaneously performed on both ends of the folding roof. Another essential advantage of the folding roof according to the invention is that a tensile load is always applied to the drive cable when the folding roof is closed.
[0006]
It is advantageous to provide both motors in the center of the frame member.
In order to make the range of the side members of the frame as narrow as possible, the drive cables of one drive cable pair are each guided in a horizontal plane within the range of the frame side members, and the horizontal guide surfaces of both drive cable pairs are vertically divided into two layers. Is advantageous. On the other hand, the drive cable is guided in one layer in a plane common to the range of the frame front member and the frame rear member. When the drive cable pair is guided to the frame side region in two layers, the drive cable pair travels in the range of the frame end member (frame front member or frame rear member) reached by being guided at different levels. to compensate for the level difference, on the frame corner members, the extent of binding between the frame side members and the frame end members is provided with a guide which Ru is raised to the inclined surface shape for the drive cable pairs.
[0007]
Two diagonally opposing frame corner members are formed identically with respect to the drive cable guide, i.e., the mutually opposite frame corner members each have the same guide slope and the other diagonally opposite It is advantageous if the frame corner members are configured such that both frame corner members have guides provided in a common horizontal plane for the drive cable pair.
[0008]
In order to further reduce the manufacturing cost of the frame corner member, the frame corner member is divided into two parts, the same two base portions for the diagonally opposite frame corner members, and two different members for the base portions, that is, the guide slopes It is comprised from the insertion member which has a surface, and the insertion member without a guide inclined surface. In some cases, all four bases of the frame corner member can be formed identically, and only the plug members that face each other in the diagonal direction can be formed differently one by one. In some cases, the cable channel can be mirrored to the plug-in member with minimal cost.
[0009]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below in detail with reference to the drawings.
The vehicle roof 1 is provided with a roof opening 2 that can be selectively opened or closed at least partially by a hood seat 3.
The hood seat 3 constitutes the hood portion shown in FIG. 2, the seat front end is reinforced by the front fixing member 4, and the seat rear end is reinforced by the rear fixing member 5. The fixing members 4; 5 are connected to each other by a fastening belt or a fastening rope that extends laterally into the pocket of the hood seat.
[0010]
The food sheet 3 is reinforced in the lateral direction by a sliding cross bar 7 extending in the lateral direction and a folding cross bar 8 in the middle of the cross bar. In this case, it is preferable that the crossbars 7; 8 extend through the double wall receiving pockets of the food sheet. The cross bars 7; 8 are connected to the mechanism of the folding roof in a known manner and in this case serve to form folds in the hood seat 3 when raised when the roof is opened. A canopy (cover) 9 is coated on the lower surface of the hood seat 3 facing the vehicle.
[0011]
The peripheral area of the roof opening 2 is generally surrounded by a roof frame 10. As shown in FIG. 3, the roof frame is composed of a frame front member 11, a frame rear member 12, and two frame side members 13; 14. These members are formed by a frame corner member 15 in a corner range. Are connected to each other. The frame thus formed is fixed to the fixed roof of the vehicle by the opposed frame 16 with the packing 17 inserted on the lower surface.
[0012]
The frame front member 11 and the frame rear member 12 are provided with recesses for receiving the electric motors 18 and 19 that form part of a driving device for driving the end portions of the folding roof at the center position. The drive device further includes a drive cable for the slider 34 to which the front fixing member 4 and the rear fixing member 5 are attached. The transition state of the drive cable in the roof frame 10 will be apparent from FIG. 4 showing the frame corner members 15 a and 15 b ′ of the roof frame 10. In the figure, the frame side member 14 (shown schematically in FIG. 3) between the frame corner members of the roof frame is not shown.
[0013]
The essential aspect of the present invention is that two electric motors (electric motors) 18; 19 are provided for opening and closing both ends of the folding roof, one of which is provided at the center of the frame front member 11. One is that the frame rear member 12 is provided. These motors 18; 19 drive a pair of reverse drive cables running in the guide channel of the roof frame 10 in a manner known per se, via each pinion.
[0014]
The drive cable pair that drives the front end of the folding roof is indicated generally by the reference numeral 20 in FIG. 4 and includes a drive cable 22 and a withdrawal cable 21. Similarly, a drive cable pair for driving the rear end of the folding roof is provided and includes a drive cable 25 and a lead-out cable 24. The drive cable pair 20 is driven by the electric motor 18, while the drive cable pair 23 is driven by the electric motor 19. In this case, the front motor 18 actively drives the drive cable 22 coupled to the front fixing member 4, while the lead-out cable 21 is connected to the other of the front motor 18 in the guide channel of the frame side member 13. It constitutes the passive end of the drive cable acting on the front fixing member 4 on the side. The same applies to the drive cable pair 23. That is, the drive cable 25 actively acts on the rear fixing member 5, while the lead-out cable 24 is guided by the frame side member 13 on the other side of the rear motor 19 and acts on the other side of the rear fixing member 5. The passive part of the drive cable
[0015]
Due to the particularity of the present invention, the drive cable pairs 20, 23 are not juxtaposed and save space in the channel (not shown in detail) in the range of the frame side member (the range of the frame side member 14 in FIG. 4). And it is guided in two layers up and down. That is, the cables 21 and 22 extend in the lower horizontal plane, while the cables 24 and 25 extend in the upper horizontal plane parallel to the horizontal plane. In other words, the drive cable 22 and the drive cable 25 extend in a common vertical plane, while the lead-out cable 21 and the lead-out cable 24 extend in other vertical planes that are laterally offset with respect to the vertical plane. .
[0016]
On the other hand, only one cable pair is provided in the range of the frame front member 11 and the frame rear member 12, that is, the drive cable pair 20 is provided in the guide channels 26 and 27 provided in the socket range of the frame front member 11. A drive cable pair 23 is provided in the guide channels 28 and 29 provided in the socket range of the frame rear member 12. The guide channels 26, 27, 28, 29 and the cables 21, 22; 24, 25 guided in these channels extend in a common horizontal plane. In the case of the embodiment shown in FIG. 4, this horizontal plane coincides with the horizontal plane in which the cables 21 and 22 of the drive cable pair 20 travel in the range of the frame side member 14.
[0017]
Based on the guide of the drive cable in the range of the frame members 11 and 12 as described above, the cables 24 and 25 extending upward in the range of the frame side member 14 need to be lowered to the level of the guide channels 28 and 29. This is because the guide channels 28 and 29 are moved from the transition portion to the frame rear member 12 to the transition portion to the frame side member at the frame corner member 15b ′, that is, along the rising inclined surface. To achieve this. The diagonally opposite frame corner member 15b is configured identically to the frame corner member 15b ′ with respect to the guide channel, that is, in this case too, the guide channel is inclined starting from the lower level of the frame front member 11. It extends up to the frame side member 14 along the surface. On the other hand, in the case of other frame corner members 15a and 15a 'that are also identically configured with respect to the guide channel and face each other in the diagonal direction, the guide channels 26 and 27 do not change in an inclined surface shape, and are shown in FIG. As described above, the guide channel moves in the common horizontal plane.
[0018]
Accordingly, two of the four frame corner members are configured identically, and each frame corner member basically has a base 30 that forms the upper part of the frame corner members 15a and 15b 'as shown in FIG. It has a two-part structure having 31. The base portions 30 and 31 are shape members configured to be mirror-image symmetric with respect to the central crossbar 7. In the range of the guide channels 26, 27, 28, 29, the bases 30, 31 open downward and have a U-shaped cross section. Inserted into the base 30; 31 of the U-shaped member is an insertion member 32; 33 that has a curved U-shape and includes guide channels 26, 27; 28, 29. In the case of the insertion member 32, these guide channels extend in a common horizontal plane, while in the case of the insertion member 33, the guide channel extends along an inclined surface rising to the frame side member 14 as described above.
[0019]
By guiding the cable up and down on the frame side members 13; 14, the member can be made essentially narrower and, therefore, on the one hand is advantageous for the inner width of the openable roof opening 2, on the other hand This contributes to a reduction in material consumption and weight of the side member. By using the same diagonally opposite two frame corner members 15b; 15b 'and 15a; 15a', more of the same members can be used, thus further reducing the manufacturing cost of the folding roof. In the case of a uniformly curved roof, the cost can be further reduced by configuring the left and right frame side members and the frame rear member as the same member.
[0020]
The present invention described in detail above has the following features.
First, a frame front member 11, a frame rear member 12, two frame side members 13 and 14, and a frame corner member 15 a that couples the frame side members 13 and 14 to the frame front member 11 and the frame rear member 12, 15b; a roof frame 10 having 15a 'and 15b' and surrounding the roof opening; guided by frame side members 13 and 14 and fixed to the front and rear fixing members 4; 5 or hooks of the folding roof (shielding sheet) An electrically driven drive cable 21 guided by the roof frame 10 for driving the slider 34 to selectively open and close the folding roof from the front and / or rear or from the front and / or rear; , 22, 24, 25, and The frame front member 11 and the frame rear member 12 are each opened and closed by a pair of drive cables 21, 22; 24, 25 that are operated in opposite directions. An electric motor 18; 19 is provided.
[0021]
Accordingly, the opening and closing operation can be performed simultaneously or independently on both ends of the folding roof with the member cost and the assembly cost being reduced, and the tensile load is always applied to the drive cable pair 20 and 23 when the folding roof is closed. it can.
Secondly, an electric motor 18; 19 is provided at the center of the frame front member 11 and the frame rear member 12.
[0022]
Thereby, the structure of the vehicle roof 1 can be configured in a substantially symmetrical shape.
Thirdly, the drive cables 21, 22; 24, 25 of the drive cable pair 20; 23 are guided in the horizontal plane in the range of the frame side members 13, 14, respectively. The horizontal guide surfaces are arranged in two layers on the top and bottom and extend.
[0023]
Thereby, the range of the frame side members 13 and 14 can be configured as thin as possible, and the roof opening 2 can be widened.
Fourth, the drive cables 21, 22; 24, 25 of the drive cable pair 20; 23 of the frame front member 11 and the frame rear member 12 are guided in a common horizontal plane, and in the range of the frame side members 13, 14. Drive cables 21, 22; 24, 25 extending into guide surfaces that are offset with respect to the common guide surface of the frame front member 11 and the frame rear member 12 are frame corner members 15 b, along the guide inclined surfaces of the common horizontal guide surface. 15b '.
[0024]
Thereby, the manufacturing cost of the frame corner members 15b and 15b ′ can be reduced.
Fifth, the frame corner members 15a and 15a ′; 15b and 15b ′ that face each other in the diagonal direction are a pair of frame corner members 15b and 15b ′ having a guide inclined surface, and a pair of frames having no guide inclined surface. The frame corner members 15a and 15a ' are formed identically.
[0025]
As a result, the manufacturing cost of the frame corner members 15a, 15b; 15a ′, 15b ′ can be further reduced.
Sixth, the two frame corner members 15a and 15a ′, which are opposite to each other in the diagonal direction, have the same base portion 30; 31, respectively. One of 15b and 15b 'has a plug member 33 with a guide ramp and the other has a plug 32 with no guide ramp.
[0026]
As a result, all four bases of the frame corner members 15a and 15b; 15a ′ and 15b ′ can be formed in the same manner, and only the insertion members 32 and 33 that face each other in the diagonal direction can be formed in a different form. The cable channel can be constructed mirror-image-symmetrically on the plug-in members 32; 33 at a minimum cost.
In addition, this invention is not limited to the said embodiment, A various deformation | transformation can be carried out.
[0027]
【The invention's effect】
According to the present invention described in detail above, it can be manufactured with the least possible part and assembly costs, both ends of the folding roof are displaced simultaneously and a tensile load is always applied to the drive cable of the drive device when the folding roof is closed.
