Fig. 3 shows a flap support apparatus 1 according to a preferred embodiment of the invention. The flap support apparatus 1 mainly includes a ball head assembly 10 and a slide rail assembly 20. The flap support apparatus 1 according to the present invention is capable of supporting the end of the flap 70, and by means of the cooperation of the ball head assembly 10 and the slide rail assembly 20, the ball head assembly 10 can move along the path provided by the slide rail assembly 20, so as to realize the retraction of the flap 70 relative to the wing 60 in the wing assembly. As shown in fig. 1 and 2, the ball head assembly 10 is fixedly attached to the wing 60 and the sled assembly 20 is fixedly attached to the flap 70, and vice versa.
Fig. 4 and 5 show perspective and cross-sectional views, respectively, of the ball head assembly 10. In the preferred embodiment, the ball head assembly 10 basically includes a base 11, a connector 12 and a ball head 13 that are assembled together to form the length-adjustable ball head assembly 10.
The mount 11 forms an attachment 32 of the ball head assembly 10 for fixedly connecting to the wing 60 or flap 70. Specifically, as shown in FIG. 1, the securement of the base 11 relative to the wing 60 may be accomplished by a plurality of fasteners. The ball 13 in the ball head assembly 10 is configured as a rolling connection of the ball head assembly 10 that is capable of rolling about a rotational centerline of the ball 13 along a guide surface 213 provided by the slide rail assembly 20. The connector 12 is disposed between the base 11 and the ball 13 for connecting the two together and is configured to provide the ball assembly 10 with an adjustment means for adjusting the amount of protrusion of the ball 13 relative to the base 11.
In a preferred embodiment, as shown in FIGS. 4 and 5, the foot 11 of the ball head assembly 10 includes a base 111 and a link 112 integrally projecting outwardly from one surface of the base 111, with the link 112 in turn being connected to the connector 12.
In the preferred embodiment, the ball head protrusion adjustment device is implemented by a threaded structure, the end surface of the connecting rod 112 far from the base 111 is recessed to form a threaded hole, the matched end of the connecting piece 12 is formed with external threads, the connecting rod 112 and the connecting piece 12 are connected through threads, and the protrusion of the connecting piece 12 relative to the threaded hole on the end surface of the connecting rod 112 can be adjusted by rotating the connecting piece 12, so that the length of the whole ball head assembly 10 can be adjusted.
Further, preferably, locking means (e.g., a fuse, a lock washer, etc.) may be provided to secure the protrusion of the protrusion adjusting means by locking the relative positions of the locking link 12 and the link 112.
In the ball head assembly 10, a rolling member 14 is provided between the connection member and the ball head 13 to effect rolling of the ball head relative to the connection member. The rolling members 14 are preferably roller bearings. The roller bearing includes an inner ring and an outer ring, and rollers disposed between the inner ring and the outer ring such that the inner ring and the outer ring are relatively rotatable by means of the rollers. The inner race of the roller bearing is secured to the connector 12 by a nut 16, specifically the inner race of the roller bearing is sleeved on one end of the connector. The outer race of the roller bearing is fixed to the ball head 13, in particular by means of a nut 16, in a central through hole of the ball head, which is preferably a stepped hole, so that the ball head 13 can be freely rotated around the connecting piece 12 on this end of the connecting piece 12 by means of the rolling element 14. Further, a shoulder portion 131 is formed in the intermediate through hole of the ball head 13, and the outer ring of the rolling member 14 abuts against the shoulder portion 131, so that the shoulder portion 131 provides support for the outer ring of the rolling member 14.
It should be appreciated that in the preferred embodiment according to the present invention, the use of the rolling members 14 effectively reduces wear of the ball 13 in the guide surface 213, prevents the ball 13 from seizing, and improves the service life and reliability of the flap supporting apparatus 1.
The outer surface of the ball 13 of the ball head assembly 10 in contact with the guide surface 213 is a spherical surface, and as can be seen in fig. 5, the spherical surface of the ball 13 is rotationally symmetrical about the central axis of the coupling 15.
Fig. 6 shows an assembled state perspective view of the slide rail assembly 20 according to the preferred embodiment of the present invention, and fig. 7 shows an exploded perspective view of the slide rail body of the slide rail assembly 20. As shown in fig. 6, the track assembly 20 includes a track body forming a track surface 213 for slidably engaging the ball head assembly 10 and an attachment 32 pivotally mounted on the track body for attachment to the wing 60 or flap 70.
As shown in fig. 7, the slide rail main body is mainly composed of a slide rail portion 21 and first and second barrier portions 22 and 23 on opposite side surfaces of the slide rail portion 21. The slide rail portion 21 has upper and lower guide surfaces 213 formed in accordance with the movement locus of the flap 70. The guide surfaces 213 on the slide rail portion 21 are provided as two-dimensional movement tracks, and preferably, the guide surfaces 213 are each arc-shaped or C-shaped. It should be appreciated that the profile of the guide surface 213 of the sled assembly 20 is precisely designed to follow the trajectory of the ball head relative to the flap 70 without impeding the movement of the flap 70 and sled body.
More specifically, the rail portion 21 forms an upper wall portion 211 and a lower wall portion 212 along the guide surface 213 such that the guide surface 22 is formed in the middle of the rail portion 21 by the lower surface of the upper wall portion 211 and the upper surface of the lower wall portion 212, and the rail portion 21 is laterally opened to laterally receive the ball head 13.
Also provided on the outer surfaces of upper wall portion 211 and lower wall portion 212 are a plurality of pairs of tabs 214, each tab 214 having a through hole for insertion of a fastener. Preferably, tabs 214 on the outer surfaces of upper wall portion 211 and lower wall portion 212 are symmetrically disposed.
Accordingly, the shutter portions 22 and 23 have shapes corresponding to the rail portions 21, respectively, and openings corresponding to the outline shapes of the rail surfaces 213 formed in the rail portions 21 are formed in the middle of the shutter portions 22 and 23, but the up-down width of the openings is smaller than the width distance between the rail surfaces 213 opposing up-down. The flap portions 22 and 23 are also integrally formed with corresponding tabs that correspond in position and shape to the tabs 214 on the slide rail portion 21, each tab also having a through hole therein.
As shown in fig. 6, after the barrier portions 22 and 23 are attached to both sides of the slide rail portion 21, respectively, the barrier portions 22 and 23 and the slide rail portion 21 can be fixed together by passing bolts through holes formed in the barrier portions and tabs on the slide rail portion 21. The openings 221 and 231 of the baffle parts 22 and 23 cooperate with the guide rail of the rail part 21 at the position 213, but since the width of the openings 22 and 23 is smaller than the distance between the upper and lower guide surfaces, after installation, the baffle parts 22 and 23 form corresponding blocking flanges along the guide surface 213, so that the ball head can be blocked in the rail part 21 so as not to be able to be detached from the guide surface 213, but to allow freedom of angular movement along the movement track and relative to the guide surface.
Further, at one end of the rail portion 21 of the rail body along the movement locus, the rail portion 21 of the rail body is formed with a hinge mechanism 30, and the hinge mechanism 30 attaches the wing 60 or the flap 70 with an attachment 32 provided thereto. Specifically, as shown in fig. 6, the hinge mechanism 30 defines a pivot shaft 31, and the pivot shaft 31 is mounted in upper and lower flanges 33 integrally extending from ends of the upper wall portion 211 and the lower wall portion 212 of the slide rail portion 21. The attachment 32 has a through hole matching the pivot shaft 31, the matching through hole being fitted over the pivot shaft 31, and the attachment 32 being interposed between the upper flange 33 and the lower flange 33, so that a relative rotational movement relationship is provided between the attachment 32 and the slide rail main body.
As can be appreciated from fig. 1, the hinge mechanism 30 provides a hinge axis of rotation of the sled body relative to the attachment 32, i.e., relative to the attached flap 70, which is generally perpendicular to the direction of movement of the flap 70. In the case where the slide rail body defines a guide surface having a two-dimensional movement locus, the hinge axis is substantially parallel to a plane in which the two-dimensional movement locus lies.
By means of the hinge mechanism 30, when the flap 70 moves laterally, the slide rail assembly 20 can swing around the hinge axis, so that the lateral freedom degree of the slide rail assembly 20 is released, and the movement blocking of the slide rail assembly 20 during the movement of the flap 70 is avoided.
Hereinafter, the operation of the flap supporting apparatus 1 according to the preferred embodiment of the present invention will be described with reference to fig. 1, 2, and 7A to 7C. The ball head assembly 10 and the sled assembly 20 are connected to the flap 70 and the wing 60, respectively, as shown in fig. 1 and 2, in an embodiment according to the present invention, the ball head assembly 10 is fixedly connected to the wing 60 and the sled assembly 20 is fixedly connected to the flap 70.
With the ball head 13 engaged to the guide surface 213 of the slide rail assembly 20, the amount of protrusion of the ball head 13 relative to the base 11 can be adjusted by rotating the connector 12, thereby compensating for manufacturing assembly errors, so that the base 11 and the attachment 32 can be suitably connected to the wing 60 and the flap 70, respectively.
When the flap 70 is retracted, a flap driving mechanism (not shown) drives the flap 70 to move, and the flap 70 drives the slide rail assembly 20 to move, and the ball 13 in the ball head assembly 10 rolls along the guide surface 213 of the slide rail assembly 20, so that the supporting function is realized during the movement of the flap 70. Specifically, as in fig. 7A, the ball 13 is located at a first end of the movement locus formed in the slide rail portion 21, that is, an end near the hinge mechanism 30, at which time the flap 70 is in the retracted position as shown in fig. 2. As the flap drive mechanism drives the flap 70 outwardly relative to the wing 60, the ball 13 rolls along the guide surface 213 of the guide track portion 21 toward the second end as shown in fig. 7B, at which point the track assembly 20 is supported by the ball 13 as the flap 70 moves outwardly until the ball 13 moves to the second end of the guide surface 213 away from the hinge mechanism as shown in fig. 7C.
During movement of the ball head assembly 10 relative to the track assembly 20, the ball head 13 provides motion restraint to the track assembly 20 in a direction perpendicular to the track surface 213. On the other hand, when there is a lateral component of the flap 70 motion, the sled body can swing about the hinge axis, releasing the lateral constraint on the flap 70.
Thus, with the flap support apparatus 1 according to the invention, a high-pair movement is achieved with the rolling element 14 nested inside the ball head 13 and combined with the guide surface of the pivotable slide rail body which accommodates the two-dimensional curved surface of the flap movement track, the point rolling on the space curve.
The sled assembly 20 and the rollable bulb 13, which are connected by the hinge mechanism 30, provide other constraints to the flap 70 than lateral movement and the direction of movement of the flap 70, support the flap 70 without impeding the movement of the flap 70, and greatly reduce vibrations of the flap 70, particularly the flap ends.
While the invention has been described in terms of preferred embodiments, it is not intended to be limiting, but rather to the invention, as will occur to those skilled in the art, without departing from the spirit and scope of the invention. Therefore, any modification, equivalent variation and modification of the above embodiments according to the technical substance of the present invention fall within the protection scope defined by the claims of the present invention.
