Description

Technical Field

[0001] The present disclosure relates to a sunroof device that opens and closes at least part of an opening formed on a roof of a vehicle by a movable panel. Background Art

[0002] Sometimes a sunroof device is provided on the roof of a vehicle. In the sunroof device, for example, a cover (movable panel) obtains a fan position (ventilation position) by completely or partially opening the opening of the roof or lifting the rear end (tilting upward). In order to move the movable panel, for example, a guide rod having a slide (cam groove) in which a guide pin can move is used (see Patent Document 1).

[0003] The sunroof device described in Patent Document 1 is a sliding / tilting type roof in which a guide pin moves in a cam groove and a movable panel moves below an outer panel of a fixed roof. A guide slit (strut) is installed on the lower surface of the movable panel, and a cam groove is provided on the strut to displaceably engage with a guide pin of a rear sliding member. The strut has a steel support portion and a resin liner overmolded on the support portion. The cam groove is demarcated by the resin liner, and a damping section is formed at a portion of the upper edge of the cam groove by forming a thick wall portion of the resin liner with a long groove.

[0005] Patent Literature

[0006] Patent Document 1: German Utility Model Application Publication No. 202004016557 Summary of the invention

[0007] Problems to be solved by the invention

[0008] In the sunroof device described in Patent Document 1, when the guide pin is located in the damping section, the guide pin is flexibly held in the vertical direction by the resin liner, so the vibration damping effect of the movable panel can be expected. However, in the case where the cam groove is a bottomed shape open to the side and the guide pin is a structure that does not penetrate the cam groove, the damping section cannot be used to give flexibility to the thick wall portion of the resin liner. Therefore, the vibration damping effect cannot be obtained.

[0009] When the movable panel is in the upward tilted position, the vibration of the movable panel tends to increase. However, in this sunroof device, when the movable panel is in the upward tilted position, the guide pin is located at the end of the cam groove, and the end of the cam groove becomes the keyhole opening. Therefore, this structure cannot achieve the vibration attenuation effect when the movable panel is in the upward tilted position.

[0010] In view of the above background, an object of the present invention is to provide a sunroof device capable of attenuating vibration when the movable panel is in an upward tilt position even if the cam groove has a bottomed structure.

[0011] Means for solving problems

[0012] In order to solve the above-mentioned problems, one embodiment of the present invention is a sunroof device (10, 110), which uses a movable panel (11, 111) to at least partially open and close an opening (3) formed on a roof (2) of a vehicle (1), and the sunroof device (10, 110) includes: a frame (20) in a frame shape, which is arranged below the roof in a manner matching the opening; a sliding member (27, 125) which is slidably arranged on the frame in the front-rear direction; a connecting member (29, 32, 129) which connects the movable panel to the sliding member; and a lifting mechanism (30, 130) which is arranged between the sliding member and the connecting member and causes the rear end of the movable panel to be raised and lowered so that the movable panel can be moved between a closed position closing the opening and a position where the rear portion is located above the opening. The lifting mechanism is a lifting mechanism for tilting between upward tilting positions, the lifting mechanism comprising: a cam groove (35, 135) with a bottom, which is arranged on one of the sliding member and the connecting member and is open to one side over its entire length; and at least one guide pin (36, 136), which is arranged on the other of the sliding member and the connecting member and protrudes into the cam groove from the side, and at least one slit (47, 147) is formed on the bottom wall (46, 146) of the cam groove defining the sliding member and the connecting member, and the slit (47, 147) passes through the bottom wall and extends in the extension direction of the cam groove with a length smaller than the length of the cam groove, and at least one of the slits is arranged at a portion of the bottom wall where at least one of the guide pins is located when the movable panel is in the upward tilting position.

[0013] According to this structure, when the movable panel is in an upwardly tilted position, at least one guide pin of the lifting mechanism supporting the movable panel is supported by the portion of the cam groove whose rigidity is reduced due to the slit. Therefore, when the movable panel in the upwardly tilted position vibrates, the vibration of the movable panel is attenuated by the lifting mechanism. Therefore, the vibration sound of the movable panel is suppressed. It should be noted that the length of at least one slit is smaller than the length of the cam groove, so even if the slit is provided on the bottom wall, the rigidity of the cam groove as a whole can be ensured.

[0014] In the above aspect, at least one of the slits (47, 147) may be provided in a portion of the bottom wall where at least one of the guide pins is located when the movable panel is in the closed position.

[0015] According to this structure, when the movable panel is in the closed position, at least one guide pin is also supported by the portion of the cam groove whose rigidity is reduced by the slit. Therefore, when the movable panel in the closed position vibrates, the vibration of the movable panel is also attenuated by the lifting mechanism.

[0016] In the above scheme, the movable panel (11, 111) can be supported on the frame in a manner that allows it to move between the closed position and the open position, wherein the open position is located in the moving direction of the sliding member relative to the closed position when viewed from above, and at least one of the slits (47, 147) is provided in the portion of the bottom wall where at least one of the guide pins is located when the movable panel is in the open position.

[0017] If at least one guide pin is supported by the portion of the cam groove provided with the slit, the vibration of the movable panel is attenuated, while the movable panel is likely to vibrate. According to this structure, when the movable panel is in the open position, the movable panel can be made less likely to vibrate.

[0018] In the above scheme, the connecting part may include a connecting rod part (32), the connecting rod part (32) having one end rotatably connected to the movable panel, the guide pin (36) includes two guide pins (36) arranged on the connecting rod part at positions separated from each other along the extension direction of the cam groove, and at least one slit (47) is separately arranged at the part of the bottom wall where the two guide pins are located when the movable panel is in the upward tilted position.

[0019] According to this structure, the link member is supported by the cam groove with low support rigidity compared to the case where only the slit is provided in the portion of the bottom wall where one of the two guide pins is located when the movable panel is in the upward tilted position. Therefore, when the movable panel in the upward tilted position vibrates, the vibration of the movable panel is effectively attenuated by the lifting mechanism.

[0020] In a scheme including the above-mentioned connecting rod component, at least one of the slits (47) may be provided in a portion of the bottom wall (46) where one of the two guide pins (36) is located when the movable panel (11) is in the closed position, and no portion of the bottom wall is provided where the other of the two guide pins is located when the movable panel is in the closed position.

[0021] According to this structure, compared with the case where slits are provided on both sides of the bottom wall where the two guide pins are located when the movable panel is in the closed position, the link member is supported by the cam groove with lower support rigidity. Therefore, the movable panel can be less likely to vibrate when the movable panel is in the closed position.

[0022] In a scheme including the above-mentioned connecting rod component, the sliding part (27) may include a metal plate component (43) and a resin component (44) formed integrally with the metal plate component, and the cam groove (35) is defined by the resin component in a manner that passes through the metal plate component in the direction of the plate thickness.

[0023] According to this structure, the cam groove is defined by the resin member, thereby reducing the sliding resistance of the guide pin. In addition, the cam groove is defined to penetrate the metal plate member in the plate thickness direction, so that the rigidity of the cam groove against the force input from the guide pin is supplemented by the metal plate member.

[0024] In a scheme including the above-mentioned connecting rod component, the sliding member (27) may include a pair of longitudinal wall portions (41) connected to each other and arranged on both sides of the connecting rod component (32), the cam grooves (35) are respectively formed on the pair of longitudinal wall portions, at least one guide pin (36) protrudes from the connecting rod component to both sides to protrude into the cam groove, and the slits (47) are formed on the bottom walls of each of the pair of longitudinal wall portions (46).

[0025] According to this structure, the panel supporting force of the guide pin can be increased by supporting both ends of the guide pin by the cam grooves of the pair of vertical wall portions. In addition, the vertical load can be supported by the guide pin in a well-balanced manner by providing slits on the bottom walls of each of the pair of vertical wall portions.

[0026] Effects of the Invention

[0027] According to the above aspect, it is possible to provide a sunroof device that can attenuate vibration when the movable panel is in the upward tilt position even if the cam groove has a bottomed structure. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0040] 《First Implementation Method》

[0041] First, refer to Figure 1 to Figure 7 A first embodiment of the present invention will be described. Figure 1 1 is a perspective view showing a closed state of a sunroof device 10 mounted on a roof 2 of an automobile 1. A rectangular opening 3 is formed on the roof 2 of the automobile 1, and the sunroof device 10 is mounted on the roof 2 in a manner that closes the opening 3. Hereinafter, the front-rear, left-right, and up-down directions are determined based on the automobile 1 with the sunroof 10 mounted on the roof 2. The sunroof device 10 is roughly bilaterally symmetrical, and the right side is shown in the figure to explain the details of the bilaterally symmetrical structure.

[0042] The sunroof device 10 includes a front panel 11 that closes the front portion of the opening 3 and a rear panel 12 that closes the rear portion of the opening 3. The front panel 11 and the rear panel 12 are arranged along the roof 2 in such a manner that their upper surfaces match the upper surface of the roof 2. The front panel 11 is a movable panel that can move relative to the roof 2, and the rear panel 12 is a fixed panel that cannot move relative to the roof 2.

[0043] The front panel 11 has a front panel main body 13 formed of a glass plate and an annular front decorative portion 14 made of resin provided on the outer periphery of the front panel main body 13. A front sealing portion 15 formed of an elastic member is provided between the outer periphery of the front decorative portion 14 and the edge of the opening 3. The rear panel 12 has a rear panel main body 16 formed of a glass plate and an annular rear decorative portion 17 made of resin provided on the outer periphery of the rear panel main body 16. A rear sealing portion 18 formed of an elastic material is provided between the outer periphery of the rear decorative portion 17 and the edge of the opening 3. The front sealing portion 15 and the rear sealing portion 18 cooperate to form an annular sealing portion on the outer peripheries of the front panel 11 and the rear panel 12, and form a sealing portion between the front panel 11 and the rear panel 12.

[0044] When the front panel 11 is driven in the opening direction by a known sliding mechanism, Figure 1 The closed position shown closing the front of the opening 3 is Figure 2 When further driven in the opening direction, the front panel 11 slides backward on the upper side of the rear panel 12, and moves to the upward tilted position of the rear part being lifted up. Figure 3 On the other hand, when the front panel 11 is driven in the closing direction by the sliding mechanism, the upper side of the rear panel 12 is moved from the upper side of the rear panel 12 to the open position of the front portion of the opening 3. Figure 3 Slide forward from the open position shown, via Figure 2 The upward tilt position shown is Figure 1 Like this, the front panel 11 can be moved to the closed position shown. Figure 1 The closed position shown is Figure 3 The sunroof device 10 can partially open and close the front portion of the opening 3 by sliding between the open positions shown. The sunroof device 10 of the present embodiment is an outward sliding sunroof in which the front panel 11 moves above (outside) the roof 2.

[0045] like Figure 3 As shown, a frame 20 in the shape of a frame supporting the front panel 11 and the rear panel 12 is installed below the roof 2 in a manner matching the opening 3 of the roof 2. The frame 20 includes left and right side members 21, which are rectangular ring-shaped along the opening 3 and extend in the front-to-back direction along the side edge of the opening 3; and a front cross member 22 and a rear cross member, which connect the front ends and rear ends of the left and right side members 21. A guide rail 24 extending in the front-to-back direction is integrally provided on each side member 21.

[0046] A driving source having an electric motor and a speed reduction mechanism is installed in the middle of the rear cross member in the left-right direction. The output end of the driving source is engaged with left and right push-pull cables for driving the front panel 11. The push-pull cables extend from the output end of the driving source in the rear cross member toward the outside of the vehicle, pass through the left and right conduits, bend forward, and then extend forward in the left and right guide rails 24.

[0047] Figure 4 yes Figure 2 IV-IV section view in Fig. Figure 4 As shown, a slider 25 is provided in the guide rail 24 in a manner that allows it to slide in the front-to-back direction. The slider 25 is combined with a push-pull cable. The slider 25 includes a front slider 26, a rear slider 27 disposed behind the front slider 26, and a connecting slider 28 that connects the front slider 26 and the rear slider 27. The front slider 26 and the rear slider 27 are connected by the connecting slider 28 in a manner that allows them to rotate around a transverse axis and cannot move away from each other in the front-to-back direction. Therefore, the front slider 26 and the rear slider 27 are pushed and pulled by the push-pull cable, so that they slide back and forth synchronously with each other.

[0048] The left and right stays 29 for connecting the front panel 11 with the slider 25 are fixed to the lower surface of the front panel 11. Each stay 29 is made of a metal plate extending in the front-back direction. The stay 29 acts as a connecting member connecting the front panel 11 with the slider 25. A lifting mechanism 30 for lifting the front panel 11 is provided between the slider 25 and the stay 29.

[0049] The lifting mechanism 30 tilts the front panel 11 between a closed position in which the opening 3 is closed and an upward tilted position in which the rear portion is located above the opening 3. The center of the tilting movement at this time is near the front end of the front panel 11. That is, the lifting mechanism 30 lifts and lowers the rear end of the front panel 11. In addition, the lifting mechanism 30 tilts the front panel 11 between an upward tilted position and a raised position in which both the front and rear portions are located above the opening 3. The center of the tilting movement at this time is near the rear end of the front panel 11. That is, the lifting mechanism 30 lifts and lowers the front end of the front panel 11. The lifting mechanism 30 remains in the position in which the front panel 11 is raised when the front panel 11 is between the raised position and the open position. It should be noted that the open position is located behind the closed position as the moving direction of the slider 25 when viewed from above.

[0050] The front slider 26 is connected to the front of the support rod 29 via the front link member 31. The rear slider 27 is connected to the rear of the support rod 29 via the rear link member 32. The front link member 31 is connected to the support rod 29 so as to be rotatable around a lateral axis. The front slider 26 is formed with a bottomed front cam groove 33 that is open to one side over its entire length. The front cam groove 33 has a length in the front-to-back direction and the up-down direction. The front link member 31 is integrally provided with a front guide pin 34 that protrudes to the side. The front link member 31 protrudes into the front cam groove 33 from the side through the front guide pin 34, so that it can be slidably connected to the front slider 26. The front slider 26 functions as a connecting member that connects the front panel 11 and the slider 25.

[0051] The rear link member 32 is connected to the support rod 29 so as to be rotatable around a transverse axis. The rear slider 27 is formed with a bottomed rear cam groove 35 which is open to one side over its entire length. The rear cam groove 35 has a length in the front-rear direction and the up-down direction. The rear link member 32 is integrally provided with two rear guide pins 36 protruding laterally. The rear link member 32 is slidably connected to the rear slider 27 by causing the rear guide pins 36 to protrude from the side into the rear cam groove 35. The two rear guide pins 36 are arranged at positions separated from each other in the extension direction of the rear cam groove 35. The rear link member 32 functions as a connecting member that connects the front panel 11 to the slider 25.

[0052] Figure 5 yes Figure 4 The V-V section view in the figure. Figure 5 As shown, the rear sliding member 27 includes a pair of longitudinal wall portions 41 which are arranged to be separated from each other in the transverse direction via the rear link member 32. The pair of longitudinal wall portions 41 are connected to each other. Each longitudinal wall portion 41 has an L-shaped cross-sectional shape, and includes a metal plate member 43 extending in the front-rear direction and a resin member 44 formed integrally with the metal plate member 43. An opening portion is formed through the portion of the metal plate member 43 where the rear cam groove 35 is arranged, and the opening portion has a width wider than the width (height) of the rear cam groove 35. The rear cam groove 35 is demarcated by the resin member 44, and the opening portion penetrates the metal plate member 43 in the plate thickness direction.

[0053] The rear cam groove 35 is formed on the opposite surfaces of the pair of vertical wall portions 41 so that the open ends face each other. Two pin holding holes 32a are formed in the rear link member 32 so as to penetrate in the left-right direction. A rear guide pin 36 is fitted into each pin holding hole 32a. The rear guide pin 36 protrudes from both side surfaces of the rear link member 32 to both sides, and the protruding end 36a protrudes into the rear cam groove 35 of the two vertical wall portions 41.

[0054] A slit 47 having a width narrower than the width (height) of the rear cam groove 35 is formed on the bottom wall 46 of each rear cam groove 35, that is, a thin wall portion of the resin member 44 defining the bottom of the rear cam groove 35. The slit 47 extends in the extending direction of the rear cam groove 35. The slit 47 has a length smaller than the length of the slit 47 in the extending direction. A plurality of slits 47 are formed at intervals in the extending direction of the rear cam groove 35 on the bottom wall 46 of each rear cam groove 35 (see Figure 7 In the present embodiment, three slits 47 are formed on the bottom wall 46 of each rear cam groove 35. The three slits 47 of each of the two vertical wall portions 41 are formed at positions matching each other.

[0055] Figure 6 It is shown Figure 4 The lifting mechanism 30 is shown in the following operation diagrams: (a) closed state, (b) upward tilted state, and (c) open state. Figure 6 As shown in (a), the closed state of the sunroof device 10 is the state where the slide member 25 is located at the frontmost position. The front guide pin 34 is located at the rear of the front cam groove 33, and the two rear guide pins 36 are located at the rear side of the rear cam groove 35. The front link member 31 and the rear link member 32 are in the most collapsed position. The front panel 11 extends parallel to the roof 2 at the lowest position.

[0056] like Figure 6 As shown in (b), in the upward tilt state of the sunroof device 10, Figure 6 Compared with the state (a), the slider 25 is located at the rear. The front guide pin 34 is located in the middle of the front cam groove 33, and the two rear guide pins 36 are located in the middle of the rear cam groove 35. The front link member 31 is in a lying posture, while the rear link member 32 is in a lying posture. Figure 6 The front panel 11 is lifted up at the rear and tilted relative to the roof 2.

[0057] like Figure 6 As shown in (c), the open state of the sunroof device 10 is the state in which the slide member 25 is located at the rearmost position. The front guide pin 34 is located in front of the front cam groove 33, and the two rear guide pins 36 are located in front of the rear cam groove 35. The front link member 31 is erected, and the rear link member 32 is connected to the Figure 6 The front panel 11 is further raised than the state (b). The front panel 11 is extended parallel to the roof 2 at the highest position. It should be noted that when the front panel 11 is in the raised position, the height and extension direction of the front panel 11 relative to the roof 2 are the same as those of the front panel 11. Figure 6 The same as the open state of (c).

[0058] Figure 7 It is shown Figure 6The corresponding operation diagrams of the rear sliding member 27 in (a) the closed state, (b) the upward tilted state, and (c) the open state. Figure 7 As shown in (a), when the sunroof device 10 is in the closed state, the portion of the bottom wall 46 of the rear cam groove 35 where the front rear guide pin 36 is located is not provided with a slit 47. On the other hand, the portion of the bottom wall 46 where the rear guide pin 36 is located on the rear side is provided with a slit 47.

[0059] like Figure 7 As shown in (b) of FIG. 1 , when the sunroof device 10 is in the upward tilted state, the bottom wall 46 where the two rear guide pins 36 are located is provided with slits 47. Figure 7 As shown in (c) , when the sunroof device 10 is in the open state, the slits 47 are not provided in the portion of the bottom wall 46 where the two rear guide pins 36 are located.

[0060] That is, three slits 47 are formed on the bottom wall 46 of the rear cam groove 35 at three locations separated from each other in the extending direction of the rear cam groove 35. These slits 47 extend in the extending direction of the rear cam groove 35 with a length smaller than that of the rear cam groove 35.

[0061] The sunroof device 10 is configured as described above. Next, the effects of the sunroof device 10 will be described.

[0062] like Figure 7 As shown in (b), a slit 47 is provided at a portion of the bottom wall 46 where the rear guide pin 36 is located when the front panel 11 is in an upwardly tilted position. Thus, when the front panel 11 is in an upwardly tilted position, the rear guide pin 36 of the lifting mechanism 30 supporting the front panel 11 is supported by a portion of the rear cam groove 35 whose rigidity is reduced due to the slit 47. Therefore, when the front panel 11 in an upwardly tilted position vibrates, the vibration of the front panel 11 is attenuated by the lifting mechanism 30. Therefore, the vibration sound of the front panel 11 is suppressed. It should be noted that the length of at least one slit 47 is smaller than the length of the rear cam groove 35, and therefore, even if the slit 47 is provided on the bottom wall 46, the overall rigidity of the rear cam groove 35 can be ensured.

[0063] like Figure 7 As shown in (a), the portion of the bottom wall 46 where the rear guide pin 36 is located when the front panel 11 is in the closed position is also provided with a slit 47. Thus, when the front panel 11 is in the closed position, the rear guide pin 36 is also supported by the portion of the rear cam groove 35 whose rigidity is reduced by the slit 47. Therefore, when the front panel 11 in the closed position vibrates, the vibration of the front panel 11 is also attenuated by the lifting mechanism 30.

[0064] As described above, the front panel 11 is supported on the frame 20 so as to be movable between the closed position and the open position which is located in the moving direction of the rear slider 27 relative to the closed position when viewed from above. When the rear guide pin 36 is supported by the portion of the rear cam groove 35 provided with the slit 47, the vibration of the front panel 11 is attenuated, while the front panel 11 is easily vibrated. In this embodiment, as Figure 7 As shown in (c), the portion of the bottom wall 46 where the rear guide pin 36 is located when the front panel 11 is in the open position is not provided with the slit 47. Thus, when the front panel 11 is in the open position, the front panel 11 is not easily vibrated.

[0065] like Figure 5 to Figure 7 As shown in FIG. 1 , a rear link member 32 is provided as a connecting member for connecting the front panel 11 to the slider 25. The rear link member 32 has one end rotatably connected to the front panel 11. In addition, two rear guide pins 36 are provided on the rear link member 32 at positions separated from each other in the extending direction of the rear cam groove 35. Figure 7 As shown in (b), the portions of the bottom wall 46 where the two rear guide pins 36 are located when the front panel 11 is in the upward tilted position are provided with slits 47 separated from each other. Thus, compared with the case where only the portion of the bottom wall 46 where one of the two rear guide pins 36 is located when the front panel 11 is in the upward tilted position is provided with the slit 47, the rear link member 32 is supported by the rear cam groove 35 with low support rigidity. Therefore, when the front panel 11 in the upward tilted position vibrates, the vibration of the front panel 11 is effectively attenuated by the lifting mechanism 30.

[0066] like Figure 7 As shown in (a), when the front panel 11 is in the closed position, a portion of the bottom wall 46 where one (in this embodiment, the rear side) rear guide pin 36 is located is provided with a slit 47. On the other hand, when the front panel 11 is in the closed position, a portion of the bottom wall 46 where the other (in this embodiment, the front side) rear guide pin 36 is located is not provided with a slit 47. Thus, compared with a case where both portions of the bottom wall 46 where the two rear guide pins 36 are located are provided with slits 47 when the front panel 11 is in the closed position, the rear link member 32 is supported by the rear cam groove 35 with high support rigidity. Therefore, when the front panel 11 is in the closed position, the front panel 11 is not easily vibrated.

[0067] like Figure 5As shown, the rear slider 27 includes a metal plate member 43 and a resin member 44 formed integrally with the metal plate member 43. Furthermore, the rear cam groove 35 is defined by the resin member 44 so as to penetrate the metal plate member 43 in the plate thickness direction. By defining the rear cam groove 35 by the resin member 44, the sliding resistance of the rear guide pin 36 is reduced. Furthermore, by defining the rear cam groove 35 so as to penetrate the metal plate member 43 in the plate thickness direction, the rigidity of the rear cam groove 35 against the force input from the rear guide pin 36 is supplemented by the metal plate member 43.

[0068] The rear slider 27 includes a pair of longitudinal wall portions 41 connected to each other and arranged on both sides of the rear link member 32. The rear cam grooves 35 are formed in the pair of longitudinal wall portions 41, and the rear guide pins 36 protrude from the rear link member 32 to both sides so as to protrude into the rear cam grooves 35. In addition, slits 47 are formed in the bottom walls 46 of each of the pair of longitudinal wall portions 41. As described above, the rear cam grooves 35 of the pair of longitudinal wall portions 41 support both ends of the rear guide pin 36, so that the panel support force of the rear guide pin 36 is increased. In addition, by providing the slits 47 in the bottom walls 46 of each of the pair of longitudinal wall portions 41, the vertical load is supported by the rear guide pin 36 in a well-balanced manner.
