Description

Technical Field

[0001] This utility model relates to the field of vehicle auxiliary equipment technology, specifically to a car landing ladder. Background Technology

[0002] Car roof ladders are essential equipment for modern outdoor activities, designed to meet the multi-functional needs of vehicle users. This innovative component is primarily aimed at outdoor enthusiasts who frequently need to access rooftop gear, especially in off-road adventures and long-distance travel. It provides a safe and convenient solution when placing tents, suitcases, or other large equipment. Through a carefully designed ergonomic structure, the component significantly reduces climbing difficulty while ensuring stability and safety during use. In terms of material selection, the manufacturer has fully considered the special requirements of outdoor environments, using lightweight yet exceptionally strong materials to ensure both portability and the ability to withstand the wear and tear of frequent use.

[0003] Currently, vehicle ladders on the market are prone to contact with the vehicle body during deployment and retraction, posing a risk of scratching the paint. In addition, most existing ladders use integral molding or fixed connection for the pedal part. When a part of the pedal wears or is damaged due to long-term use, the user needs to replace the entire pedal assembly, which is not only cumbersome to operate, but also increases the cost of use and maintenance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1-4 As shown, this utility model provides a car landing ladder, including two sets of telescopic rods 1 and multiple pedal bases 2. The pedal bases 2 are fixedly connected between the two sets of telescopic rods 1. An upper crossbar 3 is fixedly connected to the top of the telescopic rod 1. An installation part 4 is hinged to the upper surface of the upper crossbar 3. An anti-slip pedal 13 is provided on the outer surface of the pedal base 2. A locking part 15 is fixedly connected to the middle of the bottom groove of the anti-slip pedal 13. A through hole 16 is opened inside the locking part 15. A locking groove 17 is opened on the upper surface of the pedal base 2. A limiting rod 18 is sleeved inside the pedal base 2. An inner groove 19 is opened inside the pedal base 2. A first annular permanent magnet 20 is fixedly connected to the inner surface of the inner groove 19. A second annular permanent magnet 21 is fixedly connected to the outer surface of the limiting rod 18.

[0022] Specifically, a lower crossbar 5 is fixedly connected to the lower part of the telescopic rod 1, a connecting frame 6 is fixedly connected to the lower surface of the lower crossbar 5, a magnetic block 7 is fixedly connected to the lower surface of the connecting frame 6, and an anti-slip base 8 is fixedly connected to the bottom end of the telescopic rod 1. The magnetic block 7 can be attracted and fixed to the vehicle body after the ladder is retracted, realizing initial positioning and storage fixation. The anti-slip base 8 increases the contact area and friction between the ladder and the ground, preventing the ladder from sliding during use and improving safety and stability.

[0023] Specifically, a locking head 10 and an upper connecting strap 11 are fixedly connected to the outer surface of the upper crossbar 3. A connector 9 is rotatably connected to the outer surface of the lowermost pedal base 2 of the telescopic rod 1. A lower connecting strap 12 is fixedly connected to the outer surface of the lowermost pedal base 2 of the telescopic rod 1. The locking head 10 is used to cooperate with the connector 9 when the ladder is retracted. By tightening, the connector 9 supports the main body of the ladder. The upper connecting strap 11 and the lower connecting strap 12 are glued together by Velcro, which provides secondary support for the ladder in the retracted state and enhances the reliability of storage.

[0024] Specifically, the outer surface of the anti-slip pedal 13 is provided with a guide groove 14, and one end of the limiting rod 18 extends to the outside of the anti-slip pedal 13. The limiting rod 18 passes through the guide groove 14, and the end of the limiting rod 18 extending to the outside of the anti-slip pedal 13 is convenient for manual operation by the user to achieve quick disassembly and assembly.

[0025] Specifically, the outer surface of the engaging part 15 is adapted to the interior of the slot 17, and the outer surface of the limiting rod 18 is adapted to the interior of the through hole 16. The adaptation structure of the engaging part 15 and the slot 17 realizes the initial positioning and mechanical engagement of the anti-slip pedal 13, providing a basis for subsequent locking. The adaptation of the limiting rod 18 and the through hole 16 ensures that the limiting rod 18 can accurately penetrate the through hole 16, completing the final locking of the anti-slip pedal 13.

[0026] Specifically, the first annular permanent magnet 20 is positioned opposite the second annular permanent magnet 21, the limiting rod 18 passes through the inner groove 19 and extends to the slot 17, the outer surface of the second annular permanent magnet 21 is fitted onto the inner surface of the inner groove 19, the first annular permanent magnet 20 and the second annular permanent magnet 21 are arranged opposite each other and have the same polarity, and the repulsive force generated by the repulsion of like poles of magnets provides the driving force for the limiting rod 18 to automatically rebound, thereby realizing the rapid automatic locking of the anti-slip pedal 13.

[0027] The working principle of the above embodiments:

[0028] In use, first, the ladder is hinged and fixed to the edge of the vehicle platform via the mounting part 4. Then, the telescopic rod 1 is extended to the required length to adapt to the vehicle height. After extension, the ladder remains in a non-contact state with the vehicle body through the hinge structure of the mounting part 4, effectively preventing scratches to the paint. Users can safely go up and down by stepping on the anti-slip pedal 13. After use, the ladder is retracted to shorten its overall length. Then, the lower part of the ladder is initially attached to the vehicle body by the magnetic block 7. Next, the notch at the top of the connector 9 is inserted into the screw of the locking head 10 at the upper crossbar 3. The locking head 10 consists of a screw and a screw head threaded onto the screw. Tightening the screw head of the locking head 10 provides support for the ladder body via the connector 9. Finally, the upper connecting strap 11 and the lower connecting strap 12 fixed to the ladder are glued together with Velcro to provide secondary support for the ladder and ensure its stable and reliable storage state.

[0029] The anti-slip pedal 13 of this ladder adopts a detachable modular structure, which is convenient for individual replacement or cleaning and maintenance. The locking part 15 at the bottom is adapted to the shape of the slot 17 on the upper surface of the pedal base 2 for initial positioning. During installation, first pull the limiting rod 18 outward to disengage it from the slot 17 area. At the same time, it drives the second annular permanent magnet 21 to move closer to the first annular permanent magnet 20. The two magnets have the same polarity and generate repulsion. After aligning the locking part 15 of the anti-slip pedal 13 and inserting it into the slot 17, release the limiting rod 18. Under the action of magnetic repulsion, the limiting rod 18 automatically rebounds and passes through the through hole 16, thereby quickly locking the anti-slip pedal 13 onto the pedal base 2. During disassembly, first pull the limiting rod 18 outward, and then move the anti-slip pedal 13 upward. This realizes the convenient disassembly and assembly of the anti-slip pedal 13.
