Abstract
Description
Technical Field
[0001] The invention relates to the field of vehicle door limiting structures, and in particular to a middle sliding door limiting device. Background Art
[0002] The middle sliding door of traditional vans, box trucks and other vehicles is generally installed on the body through a guide rail, and the middle sliding door can be opened by sliding along the length of the body. In order to prevent the middle sliding door from falling out, limiters are generally set on the upper and lower guide rails. However, when the middle sliding door is opened to the maximum angle, because the middle sliding door is heavy, a greater force is required to open it. This results in a greater force on the limiter when the middle sliding door is opened to the maximum. After a certain period of use, the limiter may be damaged, causing the middle sliding door to fall out.
[0003] At present, there is a door stopper disclosed in the patent with application number CN202010996258.7, which includes: a first stopper, which is used to be arranged on the door, and the first stopper has a first stopper surface; a second stopper, which is used to be arranged on the body, at least a part of the second stopper is movable on the second stopper, and the movable part of the second stopper has a second stopper surface that cooperates with the first stopper surface to limit the position, and the second stopper includes: an adjustment structure, which is used to adjust the limit gap between the second stopper surface and the first stopper surface, so that the first stopper surface and the second stopper surface are completely fitted when limiting. The door stopper of the present invention ensures that the first stopper on the door side and the second stopper on the body side are in an absolutely fitted state, thereby improving assembly consistency.
[0004] The above-mentioned limit block is arranged between the vehicle body and the middle sliding door. When the middle sliding door is limited, the middle sliding door is simultaneously subjected to an outward force. The middle sliding door is a thin-walled part, and is easily deformed outward under the long-term action of the force, and the connection position between the middle sliding door and the sliding rail is damaged. Summary of the invention
[0005] The present invention intends to provide a middle sliding door limiting device, so as to limit the middle sliding door and prevent the middle sliding door from deforming outwards.
[0006] To achieve the above-mentioned purpose, the present invention adopts the following technical scheme: a middle sliding door limiting device, including a limiting pad and a limiting assembly, the limiting assembly includes a limiting plate and a fixed plate fixed in an L shape, the side wall of the limiting plate facing the limiting pad is a first limiting surface, the side surface of the limiting pad facing the limiting plate is a second limiting surface, the first limiting surface and the second limiting surface are relative to and can offset each other.
[0007] The beneficial effects of this program are:
[0008] 1. One of the limiting pad and limiting assembly in this solution is installed on the middle sliding door, and the other is installed at the corresponding position of the vehicle body. After the middle sliding door is opened, the middle sliding door can be limited by the cooperation of the limiting pad and the limiting assembly. When limiting, the first limiting surface and the second limiting surface are offset, that is, the limiting pad and the limiting assembly in this solution are in surface contact, the contact surface is large, and it is not easy to deform after being subjected to force. Secondly, the limiting assembly in this solution is L-shaped, so when limiting the door, the door will not be pushed outward, which can prevent the door from deforming.
[0009] 2. The limit pad and limit assembly in this solution have a simple structure and can be installed at the position where the limit is required during use. The degree of limit on the door can be changed by changing the structure of the limit pad and the limit assembly on the vehicle body along the length direction of the vehicle body, which is easy to adjust.
[0010] Furthermore, the limiting assembly includes at least one reinforcing plate, which is located on a side of the limiting plate away from the limiting pad, and the reinforcing plate is abutted against the limiting plate and the fixing plate at the same time.
[0011] The beneficial effect of this solution is that the reinforcing plate, the limiting plate and the fixing plate form a triangular support structure, which effectively increases the strength of the limiting component and avoids deformation of the limiting component.
[0012] Furthermore, the width of the fixing plate is greater than the width of the side of the limiting plate away from the fixing plate, and the width of the side of the fixing plate close to the limiting plate is greater than the width of the side away from the limiting plate.
[0013] The beneficial effects of this solution are as follows: the width of the fixing plate in this solution is larger, and the size of the first limiting surface is larger, so that when the fixing plate contacts the limiting pad, the force per unit area is smaller, further avoiding damage to the fixing component. The width of the fixing plate away from the limiting plate is smaller, and a smaller space is required for fixing.
[0014] Furthermore, the thickness of the limiting plate is greater than that of the fixing plate, a fixing hole is provided on the fixing plate, and a strip groove is provided on the side wall of the limiting plate away from the first limiting surface, and the strip groove is opposite to the fixing hole.
[0015] The beneficial effects of this solution are: the limit plate in this solution is stronger and less prone to damage. When the fastener is passed through the fixing hole to fix the limit assembly, the fastener and the limit plate are abutted against each other, which can limit the limit plate and further prevent the limit plate from bending and deformation.
[0016] Furthermore, the limiting plate and the fixing plate both include an inner plate and a plastic-coated outer shell, and the limiting plate and the inner plate of the fixing plate are fixedly connected.
[0017] The beneficial effects of this solution are: in actual implementation, the inner plate can be made of metal material, which is stronger and less likely to deform during use. The plastic-coated shell makes the limit assembly more beautiful, and when it contacts the limit pad, the plastic-coated shell plays a buffering role, reducing the sound generated by the collision between the two.
[0018] Furthermore, the side wall of the limiting cushion block facing away from the second limiting surface is an inclined surface.
[0019] The beneficial effect of this solution is that when the limiting pad is installed on the vehicle body, the inclined design enables the limiting pad to better fit the vehicle body, thereby improving the supporting effect of the vehicle body on the limiting pad and avoiding deformation of the limiting pad.
[0020] Furthermore, a step hole is provided on the limiting cushion block, and the diameter of the step hole on the side close to the limiting plate is larger than the diameter of the hole on the side close to the limiting plate.
[0021] The beneficial effect of this solution is that when the limit pad is installed by using a fastener, the head of the fastener can be installed in the step hole without being exposed to the outside, and when the limit pad is abutted against the limit plate to limit the center sliding door, the fastener will not interfere.

[0026] The following is further described in detail through specific implementation methods:
[0027] The reference numerals in the drawings of the specification include: a fixing plate 1 , a fixing hole 11 , a limiting plate 2 , a strip groove 21 , a limiting pad 3 , and a step hole 31 .
[0028] Example
[0029] The embodiment is basically as follows Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the middle sliding door limiting device includes a limiting pad 3 and a limiting assembly. The limiting assembly includes a limiting plate 2 and a fixing plate 1 fixed in an L shape. The limiting plate 2 and the fixing plate 1 both include an inner plate and a plastic-coated outer shell. Specifically, the inner plates of the limiting plate 2 and the fixing plate 1 in this embodiment are formed by bending a whole piece of metal plate, and the plastic-coated outer shell is coated on the outer side of the inner plate and attached to the inner plate. Two reinforcing plates are arranged between the limiting plate 2 and the fixing plate 1. The reinforcing plates are welded and fixed to the limiting plate 2 and the fixing plate 1 at the same time to support the limiting plate 2 and the fixing plate 1 to prevent the limiting plate 2 from deforming to the left after being subjected to force. The reinforcing plates in this embodiment are also coated in the plastic-coated outer shell.
[0030] The fixing plate 1 is provided with two fixing holes 11. The thickness of the limiting plate 2 is greater than that of the fixing plate 1. The left side wall of the limiting plate 2 is provided with a strip groove 21 in the vertical direction. The strip groove 21 extends downward to the fixing hole 11 on the right side, so that the bolts and other fasteners pass through the fixing hole 11 on the right side and abut against the limiting plate 2 to limit the limiting plate 2. The two reinforcing plates are respectively located at the front and rear sides of the strip groove 21, so that the fasteners are inserted between the two reinforcing plates after installation. When the center sliding door is limited, the fasteners cooperate with the front and rear parts of the strip groove 21 to limit the limiting assembly. Since the reinforcing plates are respectively located on both sides, the reinforcing plates can support the front and rear parts of the strip groove 21, thereby preventing the plastic-coated shell on the outer side of the inner plate from being damaged.
[0031] The width of the right end of the fixing plate 1 is greater than the width of the left end, and the width of the limiting plate 2 is equal to the width of the right end of the fixing plate 1. The limiting pad 3 is opposite to the limiting plate 2, and the thickness of the limiting pad 3 is greater than the thickness of the limiting plate 2. The right side wall of the limiting plate 2 is the first limiting surface, and the left side wall of the limiting pad 3 is the second limiting surface. When the limiting pad 3 is installed on the vehicle body, the right side wall of the limiting pad 3 is set as an inclined surface. In actual implementation, the inclination direction and inclination angle of the inclined surface are determined according to the shape of the vehicle body at the installation position, and the inclined surface can be attached to the vehicle body.
[0032] The limiting pad 3 is provided with two stepped holes 31, and the hole diameter at the left end of the stepped hole 31 is larger than the hole diameter at the right end, so that when the limiting pad 3 is installed using fasteners such as bolts, the head of the fastener can enter the stepped hole 31 without abutting against the limiting block.
[0033] The specific implementation process is as follows:
[0034] The limiting pad 3 in this solution is installed on the vehicle body, the fixing plate 1 is installed on the middle sliding door, and the limiting plate 2 is opposite to the limiting pad 3. After the middle sliding door slides to the limiting position, the limiting pad 3 abuts against the limiting plate 2 to limit the middle sliding door. When the limiting position needs to be changed, the installation position of the limiting pad 3 can be changed along the length direction of the vehicle body.
[0035] The above is only an embodiment of the present invention, and the common knowledge such as the known specific technical solutions and / or characteristics in the solution is not described in detail here. It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
