Description

Technical Field

[0001] This utility model relates to the field of automotive interior parts technology, and in particular to a limiting structure for a slide rail end cap. Background Technology

[0002] The center console, an important component of the automotive interior system, was originally designed to provide elbow support for occupants and enhance passenger comfort. However, with the rapid development of automotive technology, especially the widespread application of automation and intelligent technologies, the function and form of the center console are constantly evolving. Traditionally, the center console is usually fixed in place, but with the rise of intelligent cockpits, designers have begun to explore designing movable center consoles to accommodate the needs of different drivers and passengers.

[0003] In the design of movable car armrests, the moving structure located in the middle of the armrest generally uses a sliding assembly. Existing sliding assemblies mainly consist of a fixed platform and a sliding platform. The fixed platform has a slide rail groove with an internal slide rail, providing a track for the sliding platform. Simultaneously, the fixed platform also has a lead screw. The sliding platform and the lead screw work together; a motor drives the lead screw to rotate, causing the sliding platform to move linearly along the lead screw, thereby achieving the adjustment of the armrest's position.

[0004] However, during actual vehicle operation, if the lead screw or gearbox becomes loose for various reasons, and the vehicle experiences sudden braking or a collision, the slide rail will instantly generate a significant impact force due to inertia. At this point, because the loose lead screw cannot effectively restrain the slide rail's movement, the slide rail will shift under the impact force, exerting strong pressure on the slide rail end cap. If the slide rail end cap cannot withstand this impact force, it will be pushed off, causing the slide rail to detach from the platform. This not only severely damages the moving structure of the armrest box, affecting its normal use, but more importantly, the detached slide rail may cause accidental injuries to occupants, such as cuts or collisions, posing a significant threat to driving safety. Utility Model Content

[0005] The purpose of this invention is to solve the problem mentioned in the background art above, where, during vehicle operation, if the lead screw or gearbox becomes loose, and the vehicle encounters sudden braking or impact, the loosening of the lead screw cannot effectively restrain the movement of the slide rail due to inertia. The guide rail will generate inertia and have a large impact force, which may knock off the slide rail end cover, causing the slide rail to rush out of the fixed platform. This not only affects the normal use of the car armrest box but also poses a potential safety threat to passengers inside the vehicle.

[0006] Loose lead screw and gearbox

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A positioning end cap limiting structure includes positioning end caps disposed at both ends of a fixed platform to limit the slide rails. The positioning end caps are provided with detachable connecting rods, which can prevent the slide rails in the fixed platform from knocking the positioning end caps off due to inertia. The connecting rods can connect the positioning end caps to the fixed platform.

[0009] Preferably, the positioning end cap is provided with an abutment end that inserts into the fixed platform to abut against the slide rail. The abutment end can effectively limit the movement range of the slide rail, prevent the slide rail from excessive displacement within the fixed platform, and ensure the smooth sliding of the armrest box.

[0010] Preferably, the fixed platform is provided with a plug-in hole, and the abutment end is provided with a connecting hole. The connecting rod is inserted into the connecting hole and the plug-in hole to stably connect the positioning end cover with the fixed platform. After the connecting rod is inserted into the connecting hole and the plug-in hole, a stable and reliable fixed relationship is formed between the positioning end cover and the fixed platform, which can withstand external forces from all directions. Especially when the car brakes suddenly or bumps, it can effectively disperse and resist the impact force generated by the slide rail on the positioning end cover, ensuring that the positioning end cover will not detach from the fixed platform due to excessive force, thus ensuring the integrity of the entire sliding component structure.

[0011] Preferably, the abutting end is provided with a snap-fit ​​block, and the fixed platform is provided with a snap-fit ​​hole adapted to the snap-fit ​​block. During the vehicle's operation, the cooperation between the snap-fit ​​block and the snap-fit ​​hole can effectively prevent the positioning end cover from undergoing lateral or longitudinal displacement when subjected to external force, thereby enhancing the connection strength between the positioning end cover and the fixed platform.

[0012] When the connecting rod is inserted into the connecting hole and the insertion hole, it is positioned above the deformable locking block, and the connecting rod presses against the top of the locking block.

[0013] Preferably, the outer surface of the abutting end is provided with a positioning plate, and the end of the positioning plate facing the fixed platform is provided with a guide slope. The guide slope can help the positioning plate to enter the installation position more conveniently and accurately during installation, reducing the operation difficulty and time during the installation process. At the same time, the positioning plate can ensure that the abutting end is in the correct position after installation, ensuring the accuracy and stability of the entire limiting structure and avoiding structural instability caused by installation deviation.

[0014] Preferably, the abutting end, the snap-fit ​​block, and the positioning plate are integrally formed. The integrally formed structure has higher strength and integrity, and can better withstand the impact forces from the slide rail and the outside world.

[0015] Preferably, the locking block is triangular, and the side of the locking block facing the fixed platform has an inclined surface. During installation, the inclined surface can play a good guiding role, making it easier for the locking block to slide into the locking hole along the edge of the locking hole, reducing the installation difficulty and improving the installation efficiency. During use, the triangular locking block structure can more effectively disperse and withstand the impact force from the slide rail. Its geometry allows the locking block to distribute the force evenly on the contact surface of the locking hole when subjected to external force, preventing the locking block from coming out of the locking hole, further ensuring the stability and reliability of the limiting structure, and ensuring the safe use of the car armrest box under complex driving conditions.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The positioning end cover can be fixedly connected to the fixed platform by the connecting rod. When the car encounters bumps or sudden braking during driving, the limiting structure of the positioning end cover can effectively prevent the slide rail from rushing out of the fixed platform, thus avoiding possible injury to passengers in the car due to the slide rail coming off.

[0018] Furthermore, the snap-fit ​​block is designed to fit the snap-fit ​​hole on the fixed platform, which further enhances the connection strength between the positioning end cap and the fixed platform, preventing the positioning end cap from shifting laterally or longitudinally when subjected to external force. This complements the connection function of the connecting rod, forming multiple safeguards and greatly improving the stability and reliability of the limiting structure.

[0019] The connecting rod can also press against the upper end of the deformable snap-fit ​​block to ensure that the snap-fit ​​block can be stably snapped into the snap-fit ​​hole, further enhancing the reliability of the connection between the positioning end cover and the fixed platform.

[0030] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0031] Please see Figure 1-5 A limiting structure for a slide rail end cover includes a positioning end cover 3 located at both ends of a fixed platform 1 to limit the slide rail. The positioning end cover 3 is provided with a detachable connecting rod 32. The connecting rod 32 can prevent the slide rail in the fixed platform 1 from knocking off the positioning end cover 3 due to inertia. The connecting rod 32 can connect the positioning end cover 3 to the fixed platform 1.

[0032] The positioning end cover 3 is provided with an abutment end 31 that is inserted into the fixed platform 1 to abut against the slide rail. The abutment end 31 can effectively limit the movement range of the slide rail, prevent the slide rail from being excessively displaced within the fixed platform 1, and ensure the smoothness of the armrest box sliding.

[0033] The fixed platform 1 is provided with a plug hole 11, and the abutment end 31 is provided with a connection hole. The connecting rod 32 is inserted into the connection hole and the plug hole 11 to make the positioning end cover 3 stably connected to the fixed platform 1. After the connecting rod 32 is inserted into the connection hole and the plug hole 11, a stable and reliable fixed relationship is formed between the positioning end cover 3 and the fixed platform 1, which can withstand external forces from all directions. Especially when the car brakes suddenly or bumps, it can effectively disperse and resist the impact force generated by the slide rail on the positioning end cover 3, ensuring that the positioning end cover 3 will not be detached from the fixed platform 1 due to excessive force, thus ensuring the integrity of the entire sliding component structure.

[0034] The abutting end 31 is provided with a snap-fit ​​block 33, and the fixed platform 1 is provided with a snap-fit ​​hole 12 that is adapted to the snap-fit ​​block 33. During the driving process, the cooperation between the snap-fit ​​block 33 and the snap-fit ​​hole 12 can effectively prevent the positioning end cover 3 from being displaced laterally or longitudinally when subjected to external force, thereby enhancing the connection strength between the positioning end cover 3 and the fixed platform 1.

[0035] When the connecting rod 32 is inserted into the connecting hole and the insertion hole 11, it is positioned above the deformable locking block 33. The connecting rod 32 forms a pressure on the top of the locking block 33. This pressure force allows the locking block 33 to be more stably locked into the locking hole 12, further enhancing the reliability of the connection between the positioning end cover 3 and the fixed platform 1. It effectively resists the impact force generated by the slide rail on the positioning end cover 3 due to the inertial action of bumps or sudden braking during vehicle operation, preventing the positioning end cover 3 from detaching from the fixed platform 1.

[0036] The outer surface of the abutment end 31 is provided with a positioning plate 34. The end of the positioning plate 34 facing the fixed platform 1 is provided with a guide slope 35. The guide slope 35 can help the positioning plate 34 to enter the installation position more conveniently and accurately during installation, reducing the difficulty and time of operation during the installation process. At the same time, the positioning plate 34 can ensure that the abutment end 31 is in the correct position after installation, ensuring the accuracy and stability of the entire limiting structure and avoiding structural instability caused by installation deviation.

[0037] The abutment end 31, the snap-fit ​​block 33, and the positioning plate 34 are integrally formed. The integrally formed structure has higher strength and integrity, and can better withstand the impact from the slide rail and the outside world.

[0038] The locking block 33 is triangular, and the side of the locking block 33 facing the fixed platform 1 has an inclined surface. During installation, the inclined surface can play a good guiding role, making it easier for the locking block 33 to slide into the locking hole 12 along the edge of the locking hole 12, reducing the installation difficulty and improving the installation efficiency. During use, the triangular structure of the locking block 33 can more effectively disperse and withstand the impact force from the slide rail. Its geometry allows the locking block 33 to distribute the force evenly on the contact surface of the locking hole 12 when subjected to external force, preventing the locking block 33 from coming out of the locking hole 12, further ensuring the stability and reliability of the limiting structure, and ensuring the safe use of the car armrest box under complex driving conditions.

[0039] When installing the positioning end cover 3, the abutting end 31 of the positioning end cover 3 is aligned with the end of the fixed platform 1, so that the inclined surface of the snap-fit ​​block 33 on the abutting end 31 faces the snap-fit ​​hole 12. Then, the abutting end 31 is inserted into the fixed platform 1. During this process, the inclined surface of the snap-fit ​​block 33 will slide along the edge of the snap-fit ​​hole 12. Due to the guiding effect of the inclined surface, the snap-fit ​​block 33 can smoothly enter the snap-fit ​​hole 12. Next, the connecting rod 32 is inserted into the connecting hole of the abutting end 31 and the insertion hole 11 of the fixed platform 1, ensuring that the connecting rod 32 is fully inserted, so that the positioning end cover 3 is initially fixed to the fixed platform 1. At this time, the positioning plate 34 also enters the correct position under the action of the guide inclined surface 35, further ensuring the installation accuracy of the entire limiting structure.

[0040] During normal vehicle operation, when the armrest box sliding platform 2 moves, the slide rail slides within the fixed platform 1. The positioning end cover 3 abuts against the slide rail through the abutment end 31, limiting the range of movement of the slide rail. When the vehicle experiences bumps or sudden braking, the connecting rod 32 and the locking block 33 can effectively prevent the slide rail from impacting the positioning end cover 3 due to inertia, avoiding the positioning end cover 3 from being knocked off, thereby ensuring the stability of the slide rail within the fixed platform 1, ensuring the normal use of the armrest box and the safety of passengers inside the vehicle.

[0041] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the stated principles, the implementation of the present invention may have any variations or modifications.
