TECHNICAL FIELD

[0001] The utility model relates to the field of door limiting structure, specifically relates to middle sliding door limiting device. BACKGROUND

[0002] The middle sliding door of conventional van, van and the like is generally installed on the vehicle body through guide rail, and the middle sliding door can be opened by sliding along the length of the vehicle body, in order to prevent the middle sliding door from coming off, a limiter is generally arranged on the upper guide rail and the lower guide rail, but when the middle sliding door is opened to the maximum angle, because the middle sliding door is heavy, a large force is required to open it, which results in that the limiter is subjected to a large force when the middle sliding door is opened to the maximum, and the limiter is damaged after a certain period of use, resulting in the middle sliding door coming off.

[0003] At present, there is a patent disclosed in the patent with the application number CN202010996258.7, which discloses a door limiting block, comprising: a first limiting block arranged on the door, the first limiting block having a first limiting surface; a second limiting block arranged on the vehicle body, at least a part of the second limiting block being movable on the second limiting block, the movable part of the second limiting block having a second limiting surface cooperating with the first limiting surface for limiting, the second limiting block comprising: an adjusting structure for adjusting the limiting gap between the second limiting surface and the first limiting surface, so that the first limiting surface and the second limiting surface are completely fitted when limiting. The door limiting block of the utility model ensures that the first limiting block on the door side and the second limiting block on the vehicle body side are in an absolutely fitted state, improving the assembly consistency.

[0004] The above-mentioned limiting block is arranged between the vehicle body and the middle sliding door, when the middle sliding door is limited, the middle sliding door is subjected to an outward force at the same time, and the middle sliding door is a thin-walled part, which is easily deformed outward under the long-time action of the force, and the connection position of the middle sliding door and the slide rail is damaged. UTILITY MODEL CONTENTS

[0005] The utility model intends to provide a middle sliding door limiting device to avoid the outward deformation of the middle sliding door while limiting the middle sliding door.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a middle sliding door limiting device, comprising a limiting pad and a limiting assembly, the limiting assembly comprising an L-shaped fixed limiting plate and a fixed plate, the side wall of the limiting plate facing the limiting pad being a first limiting surface, the side of the limiting pad facing the limiting plate being a second limiting surface, the first limiting surface and the second limiting surface being opposite and abutting.

[0007] The beneficial effects of the present scheme are as follows:

[0008] 1. One of the limiting pad and the limiting assembly in the scheme is installed on the center sliding door, and the other is installed at the corresponding position of the vehicle body. After the center sliding door is opened, the center sliding door can be limited through the cooperation of the limiting pad and the limiting assembly, and when limited, the first limiting surface and the second limiting surface abut, that is, the limiting pad and the limiting assembly in the scheme are in surface contact, the contact area is large, and it is not easy to deform under stress. Secondly, the limiting assembly in the scheme is L-shaped, so when the door is limited, the door will not be pushed outward, and deformation of the door can be avoided.

[0009] 2. The structure of the limiting pad and the limiting assembly in the scheme is simple, and when used, it can be installed at the position that needs to be limited. The limiting degree of the door can be changed by changing the structure of the limiting pad and the limiting assembly on the vehicle body along the length direction of the vehicle body, and the adjustment is convenient.

[0010] Further, the limiting assembly comprises at least one reinforcing plate, the reinforcing plate is located on the side of the limiting plate away from the limiting pad, and the reinforcing plate abuts against the limiting plate and the fixed plate at the same time.

[0011] The beneficial effects of the scheme are: the reinforcing plate, the limiting plate and the fixed plate form a triangular support structure, which effectively increases the strength of the limiting assembly and avoids deformation of the limiting assembly.

[0012] Further, the width of the fixed plate is greater than the width of the side of the limiting plate away from the fixed plate, and the width of the side of the fixed plate close to the limiting plate is greater than the width of the side away from the limiting plate.

[0013] The beneficial effects of the scheme are: the width of the fixed plate in the scheme is larger, and the size of the first limiting surface is larger, so that the force per unit area received when the fixed plate contacts with the limiting pad is smaller, further avoiding damage of the fixed assembly. And the width of the side of the fixed plate away from the limiting plate is smaller, and a smaller space is needed for fixation.

[0014] Further, the thickness of the limiting plate is greater than the thickness of the fixed plate, the fixed plate is provided with a fixed hole, the side wall of the limiting plate away from the first limiting surface is provided with a strip-shaped slot, and the strip-shaped slot is opposite to the fixed hole.

[0015] The beneficial effects of the scheme are: the strength of the limiting plate in the scheme is greater, and it is more difficult to be damaged. And when the fastener is used to fix the limiting assembly by penetrating the fixed hole, the fastener abuts against the limiting plate, which can limit the limiting plate and further avoid bending deformation of the limiting plate.

[0016] Further, the limiting plate and the fixed plate both comprise an inner plate and a plastic-coated outer shell, and the inner plates of the limiting plate and the fixed plate are fixedly connected.

[0017] The beneficial effects of the scheme are that in actual implementation, the inner plate can adopt metal material, has greater strength, and is not easy to deform in use.

[0018] Further, the side wall of the limiting pad away from the second limiting surface is a slope.

[0019] The beneficial effects of the scheme are that when the limiting pad is installed on the vehicle body, the slope design makes the limiting pad better fit the vehicle body, thereby improving the support effect of the vehicle body on the limiting pad and avoiding deformation of the limiting pad.

[0020] Further, the limiting pad is provided with a stepped hole, and the hole diameter of the side of the stepped hole close to the limiting plate is greater than the hole diameter of the side of the limiting plate.

[0021] The beneficial effects of the scheme are that when the limiting pad is installed by using the fastener, the head of the fastener can be installed into the stepped hole without being exposed, and when the limiting pad abuts against the limiting plate to limit the center sliding door, the fastener will not interfere.

Specifically, the inner plate 5 of the limiting plate 2 and the fixed plate 1 in the embodiment is bent from a whole piece of metal plate, and the plastic-coated shell is wrapped outside the inner plate 5 and attached to the inner plate 5. Two reinforcing plates 4 are arranged between the limiting plate 2 and the fixed plate 1, and the reinforcing plates 4 are welded and fixed with the limiting plate 2 and the fixed plate 1 at the same time to support the limiting plate 2 and the fixed plate 1, so as to avoid the deformation of the limiting plate 2 to the left after being stressed. The reinforcing plates 4 in the embodiment are also wrapped in the plastic-coated shell.

[0030] The fixed plate 1 is provided with two fixed holes 11, the thickness of the limiting plate 2 is greater than that of the fixed plate 1, the left side wall of the limiting plate 2 is provided with a strip-shaped groove 21 in the vertical direction, the strip-shaped groove 21 extends downward to the fixed hole 11 on the right side, so that the fasteners such as bolts pass through the fixed hole 11 on the right side and abut against the limiting plate 2 to limit the limiting plate 2. The two reinforcing plates 4 are respectively located on the front and back of the strip-shaped groove 21, so that the fasteners are clamped between the two reinforcing plates 4 after installation, and the fasteners cooperate with the front and back of the strip-shaped groove 21 when limiting the middle sliding door, so as to limit the limiting assembly. Since the reinforcing plates 4 are respectively located on the two sides, the reinforcing plates 4 can support the front and back of the strip-shaped groove 21, so as to avoid the damage of the plastic-coated shell outside the inner plate 5.

[0031] The width of the right end of the fixed plate 1 is greater than that of the left end, and the width of the limiting plate 2 is equal to that of the right end of the fixed plate 1.
