Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of automobile sliding door, in particular to a sliding door lower stopper and vehicle. BACKGROUND

[0002] The automobile sliding door is a door structure that can slide along a track to open and close, mainly composed of a sliding rail, a pulley, a door lock, a sealing device and the like, and has high space utilization rate.

[0003] In order to keep the sliding door at a set opening position, prevent the sliding door from accidentally sliding to close or further open, and ensure the safety of passengers getting on and off the vehicle, two methods are commonly used, namely, using a lower stopper and a lower hinge with a limit lock structure.

[0004] The compression deformation amount of the elastic protrusion height of the limiting plate of the existing detachable stopper determines the size of the limiting force, which is affected by the body mounting point precision and the elastic protrusion heat treatment of the limiting plate, and the size of the limiting force may fluctuate, which cannot guarantee stable limiting force, and the size of the limiting force cannot be adjusted according to the comfort of the hand feeling. UTILITY MODEL CONTENTS

[0005] To solve the technical problems in the background art that the existing stopper is easily affected by the body mounting point precision and the elastic protrusion heat treatment of the limiting plate, the size of the limiting force may fluctuate, which cannot guarantee stable limiting force, and the size of the limiting force cannot be adjusted according to the comfort of the hand feeling, the utility model provides a sliding door lower stopper.

[0006] The technical scheme of the utility model is as follows:

[0007] This utility model provides a sliding door lower limiter, including a mounting base and a limit plate. An elastic protrusion is fixedly provided on the limit plate. An adjustable limit component is threadedly connected to the mounting base. The fixed end of the limit plate is fixedly connected to the mounting base through the fixing component. One side of the free end of the limit plate abuts against the adjustable limit component. By changing the position of the adjustable limit component, the position of the free end of the limit plate is changed, thereby changing the position of the elastic protrusion. This allows for adjustment of the elastic deformation of the elastic protrusion to achieve a stable limiting force. The limit force is stable and reliable, no longer affected by the accuracy of the vehicle body mounting point or the heat treatment of the elastic protrusion of the limit plate. Furthermore, the limit force can be adjusted according to requirements, making it more versatile.

[0008] Preferably, the mounting base includes a vertical plate-shaped fixing part with several bolt holes, providing a stable and convenient installation method for the mounting base. This ensures that the limiter is firmly fixed in the corresponding position on the vehicle body, preventing loosening during the sliding door's movement. The fixing part is fixedly provided with a first snap-fit ​​part and a second snap-fit ​​part. The first snap-fit ​​part is arranged horizontally, and the second snap-fit ​​part is arranged vertically. The second snap-fit ​​part is located on one side of the first snap-fit ​​part, enabling it to connect and position with the vehicle body components from multiple dimensions. This enhances the connection strength and stability between the mounting base and the vehicle body. The limit plate is fixedly installed on the first snap-fit ​​part, ensuring a reasonable layout between the limit plate and the mounting base. This facilitates the limit plate's accurate limiting function, making the entire limiter structure more compact and reasonable, and also facilitating the later maintenance and replacement of the limit plate.

[0009] Preferably, both the first and second locking parts are L-shaped plate structures. When locking with the body parts, the L-shaped structure increases the contact area, making the locking tighter and more secure. This effectively resists various external forces and vibrations generated during the sliding door's movement, and also better disperses the force, reduces stress concentration, lowers the risk of component damage, extends the service life of the limiter, and improves the stability and reliability of the entire limit system.

[0010] Preferably, the first snap-fit ​​part and the second snap-fit ​​part are fixedly connected, which further enhances the structural strength and stability of the mounting base. There is a gap between the first snap-fit ​​part and the second snap-fit ​​part, and the fixed end of the limiting plate is inserted into the gap, which provides accurate positioning and reliable support for the installation of the limiting plate. The insertion method makes the installation process of the limiting plate simple and convenient, while ensuring a tight connection between the limiting plate and the mounting base, preventing the limiting plate from shaking or shifting during use, and ensuring that the limiting plate can accurately and stably limit the sliding door.

[0011] Preferably, the limiting plate is installed laterally on the inner side of the first engaging part, which makes the limiting plate more compatible with the movement direction and trajectory of the sliding door, and can more effectively limit the sliding door. At the same time, it can also protect the limiting plate to a certain extent, reducing the impact of external factors such as dust, debris, and collisions on the limiting plate, extending the service life of the limiting plate, ensuring the long-term stability of the limiting function, and making the overall structure of the limiter more compact, which is conducive to achieving efficient limiting function in a limited space.

[0012] Preferably, an observation groove is provided on the first locking part, which is adjacent to the elastic protrusion. Through the observation groove, the operator can directly observe the working status of the elastic protrusion, such as whether there is wear, deformation, cracks, etc., and promptly detect abnormal conditions of the elastic protrusion. Repair or replacement can be carried out before the problem worsens, avoiding unstable or failed limiting force due to damage to the elastic protrusion. This ensures the normal operation of the sliding door lower limit device and the safety of vehicle use, and improves the maintainability and reliability of the equipment.

[0013] Preferably, the main body of the limiting plate is L-shaped. On the one hand, the L-shaped structure can increase the length and strength of the limiting plate, so that it can better distribute the force when bearing the impact of the sliding door, reduce the possibility of deformation, and ensure the accuracy and stability of the limiting. On the other hand, the L-shaped shape can better match the structure of the mounting base and the vehicle body, realize a more compact layout, make full use of the limited space, and facilitate connection and collaborative work with other components, thereby improving the performance and reliability of the entire limiting system.

[0014] Preferably, a buffer block is detachably installed on the second locking part. The buffer block of the lower hinge of the sliding door is integrated into the mounting base of the limiter, which simplifies the hinge structure, facilitates installation, use and later maintenance. The limiter is buffered by rubber between hard and soft, which effectively reduces the impact wear of the pulley, and can also reduce the direct collision and impact force between the sliding door and the second locking part, reduce noise and wear, and improve the comfort of using the sliding door and the service life of the components.

[0015] Preferably, the buffer block is lower than the limiting plate, which facilitates the replacement of the buffer block and the limiting plate.

[0016] This utility model provides a vehicle, including a sliding door lower limiter. A mounting base is fixedly installed on the vehicle body. A first engaging portion engages with the lower sliding rail, and a second engaging portion engages with the vehicle body. An elastic protrusion passes through the lower sliding rail and contacts the pulley assembly. During the initial installation and adjustment of the sliding door, the limiting force can be adjusted according to the user's comfort level by adjusting the limiting component. This adjustment is not affected by the precision of the vehicle body mounting point, nor by variations in the limiting force caused by different heat treatment batches of the limiting plate. Even after long-term use, if the limiting plate undergoes plastic deformation and the limiting force weakens, a stable and reliable limiting force can still be achieved by adjusting the limiting component. Adjusting the limiting component improves the maximum operating force required for opening and closing the sliding door, effectively protecting the door retaining components and preventing self-closing of the sliding door, further enhancing the user experience. When adjusting the limiting component no longer satisfies the limiting force requirements, the limiting plate can be directly removed and replaced.

[0017] As can be seen from the above technical solutions, the advantages of this utility model are:

[0018] 1. The fixed end of the limiting plate is fixedly connected to the mounting base through a fastener. One side of the free end of the limiting plate abuts against the adjustable limiting component. In the initial stage of sliding door installation and adjustment, the limiting force can be adjusted according to the comfort of the hand by adjusting the limiting component. It is not affected by the accuracy of the vehicle body mounting point, nor by the variation in the limiting force caused by different batches of heat treatment of the limiting plate. Even if the limiting plate undergoes plastic deformation after long-term use and the limiting force weakens, it can still be adjusted by adjusting the limiting component to achieve a stable and reliable limiting force. Adjusting the limiting component can improve the maximum operating force required for opening and closing the sliding door, effectively protect the door retaining components, and more effectively prevent the sliding door from self-closing, further improving the user experience of the sliding door. When the limiting force can no longer be adjusted to meet the requirements by adjusting the limiting component, the limiting plate can be directly disassembled and replaced, resulting in low maintenance costs.

[0019] 2. The design of the first and second locking parts allows for connection and positioning with the vehicle body components from multiple dimensions, enhancing the connection strength and stability between the mounting bracket and the vehicle body. Both the first and second locking parts are L-shaped plate structures. When locking with the vehicle body components, the L-shaped structure increases the contact area, making the locking tighter and more secure. This effectively resists various external forces and vibrations generated during the sliding door's movement, and also better disperses the force, reduces stress concentration, lowers the risk of component damage, extends the service life of the limiter, and improves the stability and reliability of the entire limit system.

[0020] 3. A buffer block is detachably installed on the second locking part. The buffer block of the lower hinge of the sliding door is integrated into the mounting base of the limiter, which simplifies the hinge structure, facilitates installation, use and later maintenance. The limiter is buffered by rubber between hard and soft, which effectively reduces the impact wear of the pulley, and can also reduce the direct collision and impact force between the sliding door and the second locking part, reduce noise and wear, and improve the comfort of using the sliding door and the service life of the components.

[0021] 4. The lower limiter is directly fixed to the vehicle body by bolt connection, which simplifies the structure of the lower rail assembly, eliminates the need to strengthen the tail of the lower slide block, facilitates installation and use, and reduces manufacturing and usage costs.

[0029] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0030] Example 1

[0031] In a typical embodiment of this utility model, such as Figures 1-3 As shown, a sliding door lower limiter is proposed, including: a mounting base 1, a limiting plate 2, a fixing member 4, and an adjusting limiting member 5. The mounting base 1 is used to install and fix the lower limiter as a whole onto the vehicle body. An elastic protrusion 12 is fixedly provided on the limiting plate 2 so that it contacts the lower hinge guide wheel through the elastic protrusion 12. The limiting function is achieved by utilizing the elastic deformation of the elastic protrusion 12. One end of the limiting plate 2 (i.e., the fixed end) is fixedly connected to the mounting base 1 through the fixing member 4. The adjusting limiting member 5 is connected to the mounting base 1 by a threaded connection. One end of the limiter 5 abuts against the end of the limiter 2 away from the fixing member 4 (i.e., the free end). By changing the position of the limiter 5, the position of the free end of the limiter 2 can be changed, thereby changing the position of the elastic protrusion 12 (which can also be understood as the height of the elastic protrusion 12). This allows for adjustment of the elastic deformation of the elastic protrusion 12 to achieve a stable limiting force. The limit force is stable and reliable, no longer affected by the accuracy of the vehicle body mounting point and the heat treatment of the elastic protrusion of the limiter. Furthermore, the limit force can be adjusted according to requirements, making it more versatile.

[0032] like Figure 1 As shown, the mounting base 1 includes a first snap-fit ​​part 7, a second snap-fit ​​part 8, and a fixing part 9. The fixing part 9 is a vertical plate structure with several bolt holes 10 for bolt installation, thus allowing it to be fixedly installed on the vehicle body via bolt connection. Both the first snap-fit ​​part 7 and the second snap-fit ​​part 8 are L-shaped plate structures, and both are fixedly mounted on the fixing part 9. The first snap-fit ​​part 7 is arranged horizontally, and the second snap-fit ​​part 8 is arranged vertically. The second snap-fit ​​part 8 is located on one side of the first snap-fit ​​part 7, and there is a gap of a set size between the first snap-fit ​​part 7 and the second snap-fit ​​part 8. The first snap-fit ​​part 7 and the second snap-fit ​​part 8 are fixedly connected by a connecting part. The first snap-fit ​​part 7 is used to snap with the lower slide rail 13 on the vehicle body, and the second snap-fit ​​part 8 is used to snap with the vehicle body. With the use of the fixing part 9, the lower limiter can be quickly positioned and fixedly installed.

[0033] Since the lower limiter is directly fixed to the vehicle body by bolt connection, the structure of the lower rail assembly is simplified. There is no need to strengthen the tail of the lower slider 13, which makes it easy to install and use, and reduces manufacturing and use costs.

[0034] It is understandable that the first snap-fit ​​part 7, the second snap-fit ​​part 8, the fixing part 9, and the connecting part are integrally formed by casting.

[0035] The limiting plate 2 is horizontally fixedly installed on the inner side of the first snap-fit ​​part 7 (that is, the side of the first snap-fit ​​part 7 close to the lower slide rail 13). Specifically, one end of the limiting plate 2 is fixedly connected to the first snap-fit ​​part 7 through the fixing member 4, and the other end of the limiting plate 2 contacts the end of the adjusting limiting member 5. The adjusting limiting member 5 is threadedly connected to the first snap-fit ​​part 7.

[0036] In this embodiment, the fixing member 4 is a screw, bolt or other structure used to fix the end of the limiting plate 2. The adjusting limiting member 5 is an adjusting bolt. The adjusting bolt is threadedly connected to the first snap-fit ​​part 7, thereby changing the extension length of the adjusting bolt and thus adjusting the position of the elastic protrusion 12. It is understood that in other embodiments, the adjusting limiting member 5 may also be a stud or other structure with external threads. No further restrictions are imposed here.

[0037] Limit plate 2 is a limit spring sheet, such as Figure 1 As shown, the main body of the limiting plate 2 is L-shaped. The limiting plate 2 contains a bent section. The limiting plate 2 is fixedly connected to the first snap-fit ​​part 7 by the fastener 4. At the same time, the bent section (i.e. the fixed end) of the limiting plate 2 is inserted into the gap between the first snap-fit ​​part 7 and the second snap-fit ​​part 8 to improve the firmness of the installation position of the limiting plate 2. The free end of the limiting plate 2 is away from the second snap-fit ​​part 8. An observation groove 11 is provided on the first snap-fit ​​part 7. The observation groove 11 is adjacent to the elastic protrusion 12 so that the state of the elastic protrusion 12 can be viewed through the observation groove 11.

[0038] In this embodiment, the lower limit switch can adjust the limiting force by adjusting the setting of the limiting component 5. In addition, when the lower limit switch weakens due to long-term use, the limiting force can be adjusted by adjusting the limiting component 5 to improve the reliability of the limit. Furthermore, the limiting plate 2 can be directly replaced by removing the fixing component 4 without disassembling the entire limit switch assembly, which facilitates maintenance and reduces the maintenance cost of the limit switch assembly.

[0039] like Figure 2 and Figure 3As shown, it also includes a buffer block 3. The buffer block 3 is detachably installed on the second snap-fit ​​part 8 by fixing bolts 6, and the buffer block 3 is lower than the limiting plate 2. In this embodiment, the buffer block 3 of the sliding door lower hinge is integrated into the mounting base 1 of the limiter, which simplifies the hinge structure and facilitates installation, use and later maintenance. The buffer block 3 is a rubber buffer block, which limits the hard and soft sides through rubber buffering, effectively reducing the impact wear of the pulley.

[0040] Example 2

[0041] In a typical embodiment of this utility model, such as Figure 4 As shown, a vehicle is proposed, including: a sliding door lower limiter mentioned in Embodiment 1, a lower sliding rail 13, and a pulley assembly for sliding the lower hinge of the door. The sliding door lower limiter is located at the rear of the lower sliding rail 13. The mounting base 1 of the sliding door lower limiter is fixedly installed on the vehicle body by bolts. The first snap-fit ​​part 7 snaps onto the lower sliding rail 13, and the second snap-fit ​​part 8 snaps onto the vehicle body. The lower sliding rail 13 has a slot that allows the elastic protrusion 12 to pass through, so that the elastic protrusion 12 can contact the pulley assembly.

[0042] In the initial stage of sliding door installation and adjustment, the limiting force can be adjusted according to the comfort of the hand by adjusting the use of the limiting component 5. It is not affected by the precision of the vehicle body mounting point, nor by the variation in the limiting force due to different heat treatment batches of the limiting plate 2. Even if the limiting plate 2 undergoes plastic deformation after long-term use and the limiting force weakens, it can still be adjusted by adjusting the limiting component 5 to achieve a stable and reliable limiting force. Adjusting the limiting component 5 can improve the maximum operating force required for opening and closing the sliding door, effectively protect the door retaining components, and more effectively prevent the sliding door from self-closing, further improving the user experience of the sliding door. When adjusting the limiting component 5 can no longer adjust the limiting force to meet the requirements, the limiting plate 2 can be directly removed and replaced.

[0043] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
