Description

This invention relates to a sunroof device.

Patent Document 1 discloses a sunroof device. The sunroof device includes a movable member (referred to as a movable panel in the document) that closes the opening in the vehicle roof. The sunroof device slides the movable member in a tilted state, with its rear portion raised. The movable member is positioned in the fully open position while remaining in the tilted state.

Japanese Patent Publication No. 2016-104612

Incidentally, if a strong impact is applied to the vehicle while the movable member is in a tilted position, vibrations may cause the rear link to tilt, or, for example, high friction between the bracket support parts of the rear and front links during operation may cause a phase difference in the positions of the left and right rods.

The following describes the means and effects of solving the above problems.
The sunroof device of embodiment 1 comprises a panel provided on the roof of a vehicle, a movable member that moves between a fully closed position that closes an opening in the panel and an open position that moves away from the opening, a drive shoe that moves the movable member in the front-rear direction, a guide rail that guides the drive shoe, a rear link that tilts the movable member, a rod that rotates the rear link by transmitting the force received from the drive shoe to the rear link, and a locking device having a locking member that engages with the rod, wherein the rod moves between a first position that tilts the rear link and a second position that raises the rear link by receiving force from the drive shoe, and the locking member engages with the rod when the rod is positioned in the second position.

In this configuration, when the rod is positioned in the second position, the locking member engages with the rod, making it difficult for the rod's position to change due to vibration or other factors. This prevents the rear link from tilting when it is in the upright position, and also prevents phase differences from occurring between the left and right rods.

The sunroof device of Embodiment 2 is as follows: In the sunroof device described in Embodiment 1, the front end of the rod is located at a first front end position above the locking member when the rod is positioned at the first position, and at a second front end position below the first front end position when the rod is positioned at the second position. The locking member is positioned at a shift position that does not interfere with the front end of the rod during a predetermined period when the front end of the rod moves from the first front end position to the second front end position. This configuration allows the front end of the rod to move smoothly to the second front end position.

The sunroof device of Embodiment 3 is as follows: In the sunroof device described in Embodiment 2, the drive shoe is provided with a locking contact portion that contacts the locking member, and the locking member is configured to move to the shift position by contacting the locking contact portion. With this configuration, the locking member can be moved to the shift position by the movement of the drive shoe.

The sunroof device of Embodiment 4 is as follows: In the sunroof device described in Embodiment 3, the locking member has a contact surface that the locking contact portion contacts, and the contact surface is configured to be inclined with respect to the path through which the locking contact portion passes during the movement of the drive shoe. This configuration allows the locking member to move smoothly in conjunction with the movement of the drive shoe.

The sunroof device of Embodiment 5 is as follows: In the sunroof device described in any one of Embodiments 2 to 4, the guide rail has a rod guide groove that guides the front end of the rod to the second front end position. This configuration allows the front end of the rod to be smoothly guided to the second front end position.

The sunroof device of embodiment 6 is as follows: In the sunroof device described in any one of embodiments 1 to 5, the locking member is biased in a direction that allows it to engage with the rod. This configuration allows the locking member to smoothly engage with the rod.

The sunroof system helps to prevent the rear link from tilting and to suppress phase differences in the positions of the left and right rods.

As the rod 16 moves backward, the first rod engagement portion 74 approaches the first link engagement surface 67A, and when the first rod engagement portion 74 pushes against the first link engagement surface 67A, the rear link 15 rises up.

The second link engagement groove 67B is configured such that the second rod engagement portion 75, provided on the rear end 16D of the rod 16, slides against it. The second link engagement groove 67B is constructed by cutting out a section of the second arm surface 61D. The second link engagement groove 67B is configured to approach the first arm surface 61C while moving from the second arm surface 61D towards the arm base end 61A.

When the rear link 15 is slightly raised, the second rod engagement portion 75 of the rod 16 enters the second link engagement groove 67B. Then, when the rod 16 moves backward, the second link engagement groove 67B is pushed by the second rod engagement portion 75. This causes the rear link 15 to stand upright. In the upright position of the rear link 15, the second rod engagement portion 75 of the rod 16 is positioned close to the second link engagement groove 67B. When the rod 16 moves forward in the upright position of the rear link 15, the second link engagement groove 67B is pushed by the second rod engagement portion 75. This causes the rear link 15 to rotate and fall forward.

<Rod>
The rod 16 will be described with reference to Figures 13 and 14. The rod 16 rotates the rear link 15 by transmitting the force received from the drive shoe 13 to the rear link 15. The rod 16 extends in the front-rear direction DY. The front end 16C of the rod 16 engages with the drive shoe 13. The rear end 16D of the rod 16 engages with the rear link 15.

As shown in Figure 13, the front end 16C of the rod 16 is provided with a first rod projection 71 that engages with the drive shoe 13 and a second rod projection 72 that engages with the rod guide groove 35.

The first rod projection 71 protrudes laterally from the front end 16C of the rod 16. Specifically, the first rod projection 71 protrudes so as to enter the rod engagement groove 47 of the drive shoe 13. The second rod projection 72 protrudes from the front end 16C of the rod 16 in the opposite direction to the projection direction of the first rod projection 71. Specifically, the second rod projection 72 protrudes so as to enter the rod guide groove 35 of the guide rail 14.

Furthermore, the front end portion 16C of the rod 16 is provided with an engagement recess 73 into which the locking member 81 engages. The engagement recess 73 is configured to cut out the front end surface 16A of the rod 16. The engagement recess 73 is configured to allow the locking member 81 to enter the engagement recess 73 from the side surface 16B of the rod 16. Specifically, the engagement recess 73 opens onto both the front end surface 16A and the side surface 16B of the rod 16.

As shown in Figure 14, the rear end 16D of the rod 16 is provided with a first rod engagement portion 74 and a second rod engagement portion 75. The first rod engagement portion 74 and the second rod engagement portion 75 are provided so as to protrude from the side surface of the rear end 16D of the rod 16. The first rod engagement portion 74 is configured to contact the first link engagement surface 67A of the rear link 15. The second rod engagement portion 75 is configured to contact the second link engagement groove 67B of the rear link 15.

The operation of rod 16 will be described with reference to Figures 15 and 16.
The rod 16 moves between a first position and a second position. The rod 16 moves by being pushed forward or backward by the drive shoe 13. The first position is the position in which the rear link 15 is tilted when the rod 16 is positioned in the first position. The second position is the position in which the rear link 15 is raised when the rod 16 is positioned in the second position. The second position of the rod 16 is located further back than the first position of the rod 16. The rod 16 is positioned by the cooperative guidance of the rod engagement groove 47 and the rod guide groove 35.

The front end 16C of the rod 16 moves up and down as the rod 16 moves. The front end 16C of the rod 16 is guided in the vertical direction DZ by the rod guide groove 35 of the guide rail 14. When the rod 16 is positioned in the first position, the front end 16C of the rod 16 is located at a first front end position, above the locking member 81. When the rod 16 is positioned in the second position, the front end 16C of the rod 16 is located at a second front end position, lower than the first front end position.

When the drive shoe 13 is positioned in its initial position, the rod 16 is positioned in the first position. When the rod 16 is in the first position, the first rod projection 71 of the rod 16 is located at the rear end of the rod engagement curved portion 47B, and the second rod projection 72 of the rod 16 is located at the straight guide portion 35A of the rod guide groove 35 (see Figure 15). As the drive shoe 13 moves backward, the rod 16 is pushed by the rod engagement curved portion 47B of the drive shoe 13, causing the rod 16 to move backward. As the rod 16 moves backward, the second rod projection 72 is guided by the curved guide portion 35B of the rod guide groove 35, causing the front end portion 16C of the rod 16 to move downward (see Figure 16). Consequently, the first rod projection 71 of the rod 16 is positioned at the rod engagement straight portion 47A. At this point, the rod 16 is in the second position. As the rod 16 moves from the first position to the second position, the rear link 15 rises.

<Locking device>
The locking device 17 will be described with reference to Figures 17 to 23. Figure 17 is a plan view of the locking member 81. Figure 18 is a diagram showing the arrangement of the locking member 81, the drive shoe 13, and the rod 16. Figures 19 and 20 show the arrangement of the drive shoe 13 and the locking member 81 when the drive shoe 13 is in its initial position. Figures 21 and 22 show the arrangement of the drive shoe 13 and the locking member 81 just before the front end 16C of the rod 16 moves downward. Figure 23 shows the arrangement of the drive shoe 13 and the locking member 81 when engaged.

The locking device 17 has a locking member 81 that engages with the rod 16. Furthermore, the locking device 17 has a biasing member 82 that biases the locking member 81 (see Figure 3). The biasing member 82 is composed of a linear spring. The locking member 81 is biased by the biasing member 82 in a direction that allows it to engage with the rod 16.

The locking member 81 is rotatably mounted on the guide rail 14. The locking member 81 rotates about a rotation axis perpendicular to the bottom surface of the guide rail 14. The rotation axis of the locking member 81 is located near its front end. The rear part of the locking member 81 pivots. The locking member 81 is positioned near the bottom surface of the guide rail 14. For example, the locking member 81 is positioned on the bottom surface of the second front rail section 34.

The locking member 81 is configured to be positioned in a shift position that does not interfere with the front end 16C of the rod 16 for a predetermined period. The predetermined period is the time during which the front end 16C of the rod 16 moves from the first front end position to the second front end position as the rod 16 moves. The predetermined period is also the time during which the drive shoe 13 passes through a predetermined section near the locking member 81.

The locking member 81 is configured to move to the shift position by contacting the locking contact portion 48. Specifically, the locking member 81 has a contact surface 83 that contacts the locking contact portion 48 of the drive shoe 13.

The contact surface 83 is configured such that the locking contact portion 48 contacts the contact surface 83 when the drive shoe 13 passes through a predetermined section near the locking member 81. The contact surface 83 is configured so that the locking contact portion 48 does not contact the contact surface 83 when the drive shoe 13 is positioned outside the predetermined section. The locking member 81 rotates to the shift position when the locking contact portion 48 contacts the contact surface 83. The locking member 81 returns from the shift position to the reference position by the force of the biasing member 82 when the locking contact portion 48 ceases to contact the contact surface 83.

An example of the locking member 81 will be described with reference to Figures 17 and 18. The locking member 81 is plate-shaped (see Figure 20). As shown in Figure 17, the locking member 81 has a base portion 81B. The locking member 81 extends rearward from the base portion 81B. The base portion 81B of the locking member 81 is provided with a bearing 81C that receives the shaft portion 34C. The shaft portion 34C is provided on the second front rail portion 34 so as to extend in the vertical direction DZ (see Figure 20). The locking member 81 is provided on the second front rail portion 34 so as to rotate with the center of the shaft portion 34C as the axis of rotation. The locking member 81 is biased by a biasing member 82 so as to move from the shift position toward the reference position. The reference position of the locking member 81 is the position when the locking member 81 is rotated so that, when viewed from above, the tip portion 81A of the locking member 81 overlaps with the rod 16 (see Figures 18 and 19). When the locking member 81 is positioned at the reference position, the tip 81A of the locking member 81 overlaps with the path R described later, when viewed from above. The shift position of the locking member 81 is the position when the locking member 81 is rotated so that, when viewed from above, the tip 81A of the locking member 81 does not overlap with the rod 16 (see Figure 21). When the locking member 81 is positioned at the shift position, the tip 81A of the locking member 81 does not overlap with the path R described later, when viewed from above.

The contact surface 83 of the locking member 81 is positioned to face the side surface 49A of the locking member housing portion 49 of the drive shoe 13 in the width direction DX. The contact surface 83 of the locking member 81 is configured to be inclined with respect to the path R through which the locking contact portion 48 passes during the movement of the drive shoe 13 (see Figure 17).

As shown in Figure 17, in one example, the contact surface 83 of the locking member 81 has a first inclined surface 83A, a second inclined surface 83B extending rearward from the first inclined surface 83A, and a third inclined surface 83C extending rearward from the second inclined surface 83B.

The first inclined surface 83A is configured to incline toward the rearward side surface 49A of the locking member housing 49 when the locking member 81 is positioned at the reference position, and to intersect the path R of the locking contact portion 48. The path R of the locking contact portion 48 indicates the path that the locking contact portion 48 travels through during the movement of the drive shoe 13.

The second inclined surface 83B is configured to incline towards the rearward side surface 49A of the locking member housing 49 when the locking member 81 is positioned at the reference position, and to intersect the path R of the locking contact portion 48. The angle of the second inclined surface 83B with respect to the side surface 49A of the locking member housing 49 is smaller than the angle of the first inclined surface 83A with respect to the side surface 49A of the locking member housing 49.

The third inclined surface 83C is configured to incline toward the rear, away from the side surface 49A of the locking member housing 49, and to intersect the path R of the locking contact portion 48, when the locking member 81 is positioned in the reference position.

As shown in Figures 19 and 20, when the drive shoe 13 is positioned in its initial position, the locking contact portion 48 of the drive shoe 13 is not in contact with the contact surface 83 of the locking member 81. Therefore, the locking member 81 is positioned in its reference position. At this time, the front end portion 16C of the rod 16 is located above the locking member 81.

As shown in Figures 21 and 22, just before the front end 16C of the rod 16 is guided downward by the rod guide groove 35, the locking contact portion 48 of the drive shoe 13 contacts the contact surface 83 of the locking member 81. This causes the locking member 81 to move from the reference position to the shift position. At this time, the tip portion 81A of the locking member 81 moves to a position where it does not overlap with the front end 16C of the rod 16 in a plan view (see Figure 21). Therefore, the front end 16C of the rod 16 becomes movable downward. While the drive shoe 13 moves over a predetermined section, the locking contact portion 48 of the drive shoe 13 continues to slide against the contact surface 83 of the locking member 81. Therefore, for the duration of the drive shoe 13's movement over the predetermined section (i.e., a predetermined period), the locking member 81 is positioned in the shift position. During this predetermined period, the front end 16C of the rod 16 is guided downward by the rod guide groove 35.

When the rod 16 is positioned in the second position, the front end 16C of the rod 16 is located in the second front end position. Then, due to the movement of the drive shoe 13, the locking contact portion 48 of the drive shoe 13 separates from the contact surface 83 of the locking member 81, causing the locking member 81 to return to its reference position. At this point, the tip portion 81A of the locking member 81 is inserted into the engagement recess 73 of the rod 16 (see Figure 23). By inserting the tip portion 81A of the locking member 81 into the engagement recess 73 of the rod 16, the locking member 81 engages with the front end 16C of the rod 16. This restricts the vertical movement DZ of the front end 16C of the rod 16.

<Sunroof operation>
Referring to Figure 24, the operation of the sunroof device 5 will be explained. The operation described below is the opening operation when the movable member 12 moves from the fully closed position to the open position. The closing operation when the movable member 12 moves from the open position to the fully closed position is the reverse of the opening operation, so the explanation of the closing operation will be omitted.

(First action)
When the drive shoe 13 is in its initial position, the first rod projection 71 of the rod 16 is located at the rear end of the rod engagement curved portion 47B. As a result, as the drive shoe 13 moves rearward from its initial position, the rod 16 moves rearward from its first position. When this happens, the first rod engagement portion 74 of the rear end 16D of the rod 16 pushes against the first link engagement surface 67A of the rear link 15, causing the rear link 15 to rotate so that it stands up. Furthermore, the second rod engagement portion 75 of the rear end 16D of the rod 16 pushes against the second link engagement groove 67B of the rear link 15, causing the rear link 15 to rotate so that it stands up even further. When the rear link 15 stands up, the holding portion 62 of the rear link 15 lifts the rear of the bracket 50 of the front link 18. In this way, the rear of the movable member 12 is lifted.

(Second action)
While the rod 16 is moving from the first position to just before the second position, the front end portion 16C of the rod 16 is located at the first front end position in the vertical direction DZ. That is, the front end portion 16C of the rod 16 is located above the locking member 81. When the drive shoe 13 moves backward, the locking contact portion 48 of the drive shoe 13 comes into contact with the contact surface 83 of the locking member 81. When the drive shoe 13 moves further backward, the locking member 81 is pushed by the locking contact portion 48 and moves to the shift position. This opens a passage through which the front end portion 16C of the rod 16 can move downward. Subsequently, when the drive shoe 13 moves backward, the second rod projection 72 of the rod 16 moves along the curved guide portion 35B of the rod guide groove 35 of the guide rail 14, causing the front end portion 16C of the rod 16 to move downward. After that, the front end portion 16C of the rod 16 reaches the second front end position. Furthermore, as the drive shoe 13 moves backward, the locking contact portion 48 of the drive shoe 13 separates from the contact surface 83 of the locking member 81, and the force of the biasing member 82 returns the locking member 81 to its reference position. As a result, the tip portion 81A of the locking member 81 enters the engagement recess 73 of the rod 16. This restricts the vertical movement DZ of the front end portion 16C of the rod 16.

(Third action)
As the drive shoe 13 moves further rearward, the engagement pin 44 of the drive shoe 13 reaches the rear end of the curved portion 54B of the link groove 54 of the front link 18. As the drive shoe 13 moves further rearward, the drive shoe 13 pushes the front link 18, and the front link 18 moves rearward as the drive shoe 13 moves rearward. As a result, the first roller 55 of the front link 18 is guided to the first inclined portion 25A of the first roller groove 25 of the guide rail 14, and the second roller 56 is guided to the second inclined portion 29A of the second roller groove 29 of the guide rail 14. As a result, the front part of the front link 18 rises upward, and the front link 18 moves rearward. In this way, the opening 11A is gradually opened.

<Effect>
The operation of this embodiment will now be described. When the rod 16 is positioned in the second position, the front end 16C of the rod 16 is located in the second front end position. At this time, the rear link 15 rises up, and the rear of the movable member 12 is lifted. The state in which the rear link 15 is raised is maintained by the rod 16.

Incidentally, if a strong impact is applied to vehicle 1, the rod 16 may bend due to vibration, causing the front end 16C of the rod 16 to move upward. If the front end 16C of the rod 16 moves significantly upward, the holding force of the rear link 15 will weaken, potentially causing the rear link 15 to collapse, or creating a phase difference in the positions of the left and right rods 16, leading to malfunction. For this reason, it is preferable that the open state of the movable member 12 is maintained even when a strong impact is applied.

In this embodiment, the locking member 81 engages with the rod 16 when the rod 16 is positioned in the second position. This restricts the movement of the front end 16C of the rod 16, thereby preventing the rod 16 from flying forward due to vibration or other factors.

<Effects>
The effects of this embodiment will now be explained.
(1) In the sunroof device 5, the rod 16 moves between a first position and a second position. The second position is the position of the rod 16 that raises the rear link 15. The locking member 81 engages with the rod 16 when the rod 16 is positioned in the second position. With this configuration, when the rod 16 is positioned in the second position, the locking member 81 engages with the rod 16, making it difficult for the position of the rod 16 to change due to vibration or the like. This ensures that the rear link 15 is held securely.

(2) The front end portion 16C of the rod 16 is located at a second front end position, which is lower than the first front end position, when the rod 16 is positioned at the second position. The locking member 81 is positioned in a shift position that does not interfere with the front end portion 16C of the rod 16 during a predetermined period of time during which the front end portion 16C of the rod 16 moves from the first front end position to the second front end position. This configuration allows the front end portion 16C of the rod 16 to move smoothly to the second front end position.

(3) The drive shoe 13 is provided with a locking contact portion 48 that contacts the locking member 81. The locking member 81 is configured to move to the shift position by contacting the locking contact portion 48. With this configuration, the locking member 81 can be moved to the shift position by the movement of the drive shoe 13.

(4) The locking member 81 has a contact surface 83 that the locking contact portion 48 contacts. The contact surface 83 is configured to be inclined with respect to the path R through which the locking contact portion 48 passes during the movement of the drive shoe 13. This configuration allows the locking member 81 to move smoothly in conjunction with the movement of the drive shoe 13.

(5) The guide rail 14 has a rod guide groove 35 that guides the front end 16C of the rod 16 to the second front end position. This configuration allows for smooth guidance of the front end 16C of the rod 16 to the second front end position.

(6) In the sunroof device 5, the locking member 81 is biased in a direction that allows it to engage with the rod 16. This configuration allows the locking member 81 to smoothly engage with the rod 16.

<Other Embodiments>
The above embodiments are not limited to the above-described examples of configurations. The above embodiments can be modified as follows. In the following examples of modifications, components that are substantially the same as those in the above embodiments will be denoted by the same reference numerals as those in the above embodiments.

In this embodiment, when the drive shoe 13 is positioned in its initial position, the locking member 81 is positioned in its reference position. However, it may be configured as follows: When the drive shoe 13 is positioned in its initial position, the locking member 81 may be positioned in its shift position. In this case, the contact surface 83 of the locking member 81 is configured such that the front end portion 16C of the rod 16 moves downward after the second rod projection 72 of the rod 16 is guided by the curved guide portion 35B of the rod guide groove 35, and then the locking member 81 moves to its reference position.

In this embodiment, the tip portion 81A of the locking member 81 may be positioned on the upper surface of the front end portion 16C of the rod 16 when it engages with the rod 16. This structure also suppresses the vertical movement of the front end portion 16C of the rod 16.

In this embodiment, the locking member 81 moves its tip portion 81A in the width direction DX by rotation, but the manner in which the locking member 81 engages is not limited to this. For example, the locking member 81 may be configured to move in the front-rear direction DY. In this case, the locking member 81 is biased rearward. In this case, the front end portion 16C of the rod 16 moves downward as the second rod projection 72 of the rod 16 is guided by the curved guide portion 35B of the rod guide groove 35, and then the locking member 81 moves to the reference position.

In this embodiment, the contact surface 83 of the locking member 81 has a first inclined surface 83A, a second inclined surface 83B, and a third inclined surface 83C, and each of these surfaces is configured to be a straight line when viewed from above the locking member 81. The configuration of the first inclined surface 83A, the second inclined surface 83B, and the third inclined surface 83C is not limited to this example. For example, each of the first inclined surface 83A, the second inclined surface 83B, and the third inclined surface 83C may be configured to be curved when viewed from above the locking member 81. The first inclined surface 83A, the second inclined surface 83B, and the third inclined surface 83C may be configured to form a single, smoothly continuous curve when viewed from above the locking member 81.

The locking device 17 of this embodiment can be applied to a sunroof device 5 that has a mechanism for raising the rear link 15 by a rod 16.
