Technical Field

[0001] This utility model relates to the field of vehicle parts technology, specifically to a flipping and overlapping mechanism. Background Technology

[0002] Currently, to meet the travel needs of people with disabilities, vehicles have a tilting guide plate installed between the vehicle's carrying platform and the ground. When not in use, the tilting guide plate is stored under the carrying platform inside the vehicle. When needed, the tilting guide plate slowly extends from the vehicle. During this extension, under the influence of gravity, the extended end of the tilting guide plate falls to contact the ground, and the connecting end of the tilting guide plate flips up to overlap with the carrying platform. However, in existing systems, the tilting guide plate and the carrying platform cannot achieve a good overlap, resulting in poor flipping effect and unstable overlap. Utility Model Content

[0006] Furthermore, the eccentric connecting rod is bent twice near the flip end to form a bend that causes the flip end to be eccentrically upward, and a recess is formed between the flip end and the bend.

[0007] Furthermore, a convex limiting angle is formed on the pusher inside the vehicle body near the overlapping end. Under the action of the elastic member, the eccentric connecting rod extending from the sliding channel flips, so that the concave part engages with the limiting angle.

[0027] like Figures 1-9 As shown, this utility model provides a flipping and overlapping mechanism, which overlaps between the vehicle body a carrying platform and the inclined guide plate b. The inclined guide plate b is movably fitted into the sliding channel a1 inside the vehicle body a below the carrying platform. It includes a positioning wheel 1, an eccentric connecting rod 2, and a downward guide bar 3. The positioning wheel 1 is fixed above the outlet of the sliding channel a1 on the vehicle body a and protrudes horizontally from the vertical wall of the vehicle body a. One end of the eccentric connecting rod 2 is formed as a flipping end, and the other end is formed as an overlapping end. The flipping end is hinged to the pushing member a2 inside the vehicle body a that pushes the inclined guide plate b. An elastic element, a torsion spring, is provided at the hinge point to cause the overlapping end of the eccentric connecting rod 2 to flip towards the positioning wheel 1. The inclined guide plate b is hinged and abuts against the upper wall of the sliding channel a1 when it moves within the sliding channel a1.

One end of the downward guide bar 3 away from the outlet of the sliding channel a1 forms a guide section 31 that makes the sliding channel a1 lower. The other end forms a leading angle 32 that is consistent with the slope of the chamfer a4 at the outlet of the sliding channel a1. Here, the chamfer a4 is made of nylon material to prevent scratching the eccentric connecting rod 2. The bar body of the downward guide bar 3 is formed as a parallel section 33 that is parallel to the lower wall of the sliding channel a1.

[0028] In one embodiment of the utility model, the eccentric connecting rod 2 is bent twice near the turnover end to form a folding angle that makes the turnover end eccentric upward, and a recess 21 is formed between the turnover end and the folding angle, which can avoid the interference of the eccentric connecting rod 2 with the sliding channel a1 by the lower pressing guide bar 3.

[0029] Further, an upper convex limiting angle a21 is formed on the upper part of the pushing member a2 near the overlapping end in the vehicle body a, and under the action of the elastic member, the eccentric connecting rod 2 extending out of the sliding channel a1 is turned over, so that the recess 21 is fitted in the limiting angle a21, the eccentric connecting rod 2 is positioned by the limiting angle a21, the overlapping action is completed, the inclined guide plate b after overlapping is more stable in cooperation with the bearing platform, and the inclined guide plate b and the bearing platform do not move relatively when the passengers pass.

[0030] In one embodiment of the utility model, the eccentric connecting rod 2 is bent once near the overlapping end to form an eccentric section that makes the turnover end eccentric upward, so as to form a space 22 between the eccentric section and the shaft of the eccentric connecting rod 2, which can avoid the interference of the eccentric connecting rod 2 with the sliding channel a1 by the lower pressing guide bar 3, and the other function is to form a claw-shaped structure with the overlapping end and the eccentric section, so that the positioning wheel 1 enters the space 22 and is grabbed by the claw-shaped structure.

[0031] In one embodiment of the utility model, the overlapping end is provided with an overlapping wheel 23 that is slidingly matched with the upper wall surface of the sliding channel a1, so as to prevent the overlapping end and the upper wall surface of the sliding channel a1 from being scratched.

[0032] Further, the limiting member a3 is arranged on the vertical wall of the vehicle body a, the limiting member a3 is located above the positioning wheel 1 and blocks between the overlapping wheel 23 after cooperation with the positioning wheel 1 and the vertical wall of the vehicle body a, so that the closest point of the overlapping wheel 23 and the positioning wheel 1 is located above the half arc line of the positioning wheel 1 away from the vertical wall of the vehicle body a, which can prevent the overlapping wheel 23 from being blocked by the positioning wheel 1 and the eccentric connecting rod 2 from being unable to retreat into the sliding channel a1 during the process of the inclined guide plate b being retracted into the vehicle body a.

[0033] In one embodiment of the utility model, the vertical wall of the vehicle body a is provided with a shielding plate 4 that can cover the outlet of the sliding channel a1 and has a rotating torsion, the rotating torsion can be provided by a torsion spring, for example, one end of the shielding plate 4 is hinged to the vehicle body a, a torsion spring is sleeved on the hinge, the shielding plate 4 is arranged below the outlet of the sliding channel a1, the connecting end surface of the overlapping end hinged to the inclined guide plate b forms a hinged rod b1 with a thickness smaller than that of the inclined guide plate b, the inclined guide plate b is hinged to the eccentric connecting rod 2 through the hinged rod b1, and the hinged rod b1 is arranged on the upper part of the connecting end of the inclined guide plate b to form a rotating space for the shielding plate 4 to rotate between the hinged rod b1 and the connecting end of the inclined guide plate b.

[0034] Further, the lower part of the connecting end of the inclined guide plate b is provided with a delayed blocking plate b2, which blocks the rotating shielding plate 4, so that the action of the shielding plate 4 is later than that of the eccentric connecting rod 2 during the process of the inclined guide plate b being retracted into the vehicle body a, and the situation that the shielding plate 4 is reset before the eccentric connecting rod 2 during the process of the inclined guide plate b being retracted into the vehicle body a, and the eccentric connecting rod 2 is blocked outside the sliding channel a1, is prevented.

[0035] In one specific embodiment of the present application, the lower bottom surface of the inclined guide plate b is provided with an auxiliary guide block b3, which is abutted by the shielding plate 4 after the inclined guide plate b is completely extended out of the vehicle body a, so that the movable end of the shielding plate 4, which is not connected to the vehicle body a, is not directly in contact with the lower bottom surface of the inclined guide plate b, so as to prevent the movable end of the shielding plate 4 from directly abutting on the inclined guide plate b during the process of the inclined guide plate b being reset, mainly during the process of the inclined guide plate b being reset before being parallel to the ground, so that a diagonal bracing structure is formed between the shielding plate 4 and the lower bottom surface of the inclined guide plate b, and the reset of the inclined guide plate b is affected.

[0036] It should be understood that the specific embodiments described above are only used to explain the present application, and are not used to limit the present application. The obvious changes or modifications derived from the spirit of the present application are still within the protection scope of the present application.
