[0035] In combination Figures 1 to 4 The embodiment of the present application provides a side ladder, which comprises a first ladder 100, a second ladder 200, a locking assembly 300 and a traction assembly 400.

[0036] The first ladder 100 is arranged on the side of the vehicle; one end of the second ladder 200 is hingedly connected with the lower end of the first ladder 100 through a hinge shaft 120, and a locking ring 210 is arranged on the second ladder 200; the locking assembly 300 is arranged on the first ladder 100, and the locking assembly 300 comprises a locking tongue 310 corresponding to the locking ring 210 and a telescopic seat 320; the locking tongue 310 has a telescopic column 311, the telescopic column 311 is arranged on the telescopic seat 320, and an elastic element 321 is arranged between the locking tongue 310 and the telescopic seat 320; the elastic element 321 can be a high-performance spring, which is used to ensure reliable pushing and long-term use of the locking tongue 310; the locking tongue 310 can be arranged in the locking ring 210 under the elastic force of the elastic element 321; the traction assembly 400 is arranged on the first ladder 100, and the traction assembly 400 can drive the locking tongue 310 to move away from the locking ring 210; an avoiding inclined surface is arranged on the end surface of the locking tongue 310 close to the second ladder 200, so that the locking ring 210 can push the locking tongue 310 to retract and avoid when it is close to the locking tongue 310, and the second ladder 200 and the first ladder 100 can be smoothly locked without operating the traction assembly 400.

[0037] The side ladder provided by the embodiment is mainly arranged on the side of the vehicle through the first ladder 100, and one end of the second ladder 200 is hingedly connected to the lower end of the first ladder 100 through the hinge shaft 120, so that the second ladder 200 can be folded relative to the first ladder 100.

[0038] When the side ladder is not needed, the user can fold the second ladder 200 relative to the first ladder 100, thereby saving space and avoiding obstruction. In this process, the locking ring 210 on the second ladder 200 naturally approaches the locking tongue 310 of the locking assembly 300 preset on the first ladder 100. The locking tongue 310 first avoids the locking ring 210 by compressing the elastic member 321 when contacting the locking ring 210, and then, when the locking ring 210 corresponds to the position of the locking tongue 310, the locking tongue 310 penetrates into the locking ring 210 under the action of the elastic member 321, thereby achieving firm locking of the relative position of the first ladder 100 and the second ladder 200. This operation process is simple and fast, the locking cooperation is reliable and stable, and the safety of the side ladder in the non-use state is ensured.

[0039] When the side ladder needs to be unfolded for use, the locking tongue 310 is pulled and operated by the traction assembly 400 to drive it to disengage from the locking ring 210, thereby completing the unlocking action of the relative position of the second ladder 200 and the first ladder 100. At this time, the second ladder 200 is driven to fold relative to the first ladder 100, and the side ladder can be quickly unfolded to the use state. This unfolding process is also easy to operate, greatly improving the user's efficiency in using the utility model.

[0040] In some specific embodiments, the traction assembly 400 includes a traction rope 410, a guide seat 420, a movable piece 430, and a control seat 440. The guide seat 420 and the control seat 440 are arranged on the first ladder 100. The movable piece 430 is connected with the telescopic column 311. The guide seat 420 is located on the side of the movable piece 430 away from the locking tongue 310. The traction rope 410 is arranged through the guide seat 420. One end of the traction rope 410 is connected with the movable piece 430, and the other end of the traction rope 410 is arranged on the control seat 440. In actual operation, the user only needs to simply pull the end of the traction rope 410 at the guide seat 420 to easily pull and move the movable piece 430. With the movement of the movable piece 430, it further drives the locking tongue 310 to move relative to the locking ring 210, thereby reliably releasing the locking state of the first ladder 100 and the second ladder 200. This unlocking method is not only simple and easy to operate, but also greatly improves the convenience of operation, so that the user can easily complete the unlocking action from a position away from the locking tongue 310.

[0041] It is worth mentioning that the design position of the control seat 440 is also very flexible. Although it is usually arranged on the first ladder 100, it can also be flexibly installed at any position of the vehicle according to actual use requirements and scene changes. This design not only further enhances the convenience of the unlocking operation, but also greatly improves the user's experience.

[0042] In some specific embodiments, the traction rope 410 is sleeved with a guide pipe 130, which is arranged on the first ladder 100. The guide pipe 130 cannot be ignored. It mainly undertakes two functions: first, it provides necessary protection for the use of the traction rope 410. In actual use, the traction rope 410 may be damaged due to various factors (such as friction, wear, external environmental influence, etc.), thereby affecting its normal use. The presence of the guide pipe 130 provides effective protection for the traction rope 410, greatly prolonging its service life. Specifically, the guide pipe 130 can also be rigid to further improve the protection capability of the traction rope 410.

[0043] Secondly, the guide pipe 130 also plays a role in moving guidance. The traction rope 410 needs to maintain a certain path and trajectory during traction to ensure that it can accurately pull the movable part 430, thereby realizing the movement of the locking tongue 310. The design of the guide pipe 130 is like a clear "road", which provides clear guidance for the movement of the traction rope 410, ensuring the use reliability of the traction rope 410. In this way, even in complex or unfavorable environments, the traction rope 410 can maintain stable operation and will not deviate or jam.

[0044] As shown in Figure 6 In some specific embodiments, the control seat 440 is rotatably provided with a control disc 441, and the end of the traction rope 410 away from the movable part 430 is connected to the side of the control disc 441. The traction rope 410 can be pulled by rotating the control disc 441. The benefits brought by this design are obvious. First of all, it greatly simplifies the user's operation process, making the action of pulling the traction rope 410 more convenient and labor-saving. Users no longer need to struggle to pull the rope, but only need to gently rotate the control disc 441 to achieve the same effect, which undoubtedly improves the efficiency and comfort of the operation.

[0045] Secondly, the design of the control disc 441 also ingeniously reduces the space required when pulling the traction rope 410. Traditional direct pulling methods often require a larger operating space, and operation in limited space can be restricted. However, the control disc 441, through its rotating characteristics, allows users to operate in a smaller space, which is undoubtedly a great advantage for those with limited space.

[0046] In some specific embodiments, the side of the control disc 441 is provided with a toggle piece 442; the design of this toggle piece 442 is not only simple and elegant, but also very practical. Users can easily rotate the control disc 441 by toggling the toggle piece 442, thereby achieving the pulling operation of the traction rope 410.

[0047] The benefit of this design is that it provides users with a more intuitive and easy-to-operate control method, making it more labor-saving and convenient to operate using the toggle piece 442. Instead of having to hold and rotate the entire control disc 441, users can achieve the same effect with just a slight toggle. This not only reduces the difficulty of operation, but also improves operational efficiency.

[0048] In some specific embodiments, multiple safety considerations are incorporated into the design of the toggle piece 442. Specifically, the toggle piece 442 is ingeniously designed and placed inside the control seat 440 when not in use, i.e., when the user has not performed an unlocking operation. This design not only maintains the neatness and beauty of the product's appearance, but more importantly, it ensures that the toggle piece 442 does not protrude in the non-operation state.

[0049] This design detail of the toggle piece 442 is particularly critical. Its outermost end is strictly controlled within the range of the outer plane of the first ladder 100. This means that during daily use or storage, the toggle piece 442 will not accidentally protrude or be exposed in a position that is easily touched by mistake. In this way, even if the user or onlooker accidentally touches the area near the ladder, the accidental unlocking of the second ladder 200 and the first ladder 100 caused by mistakenly touching the toggle piece 442 is avoided, effectively avoiding potential safety hazards.

[0050] In some specific embodiments, the control seat 440 is arranged at the end of the first ladder 100 close to the hinge shaft 120, i.e., the control seat 440 is located at the bottom of the first ladder 100; such a layout design has significant advantages. First, placing the control seat 440 at the bottom of the first ladder 100 allows users to more easily access it during use. Whether standing, bending over, or squatting, users can access the control seat 440 in a relatively natural and comfortable position, thereby performing the necessary operations.

[0051] Secondly, this design also takes into account the differences in height and usage habits of different users. By placing the control seat 440 at a relatively low position, it ensures that users of all heights can operate in a relatively consistent and comfortable posture, thereby improving the product's versatility and user experience.

[0052] As Figure 5 shown, in some specific embodiments, the traction assembly 400 further includes a transfer seat 450, the lock tongue 310 is symmetrically provided with two, the transfer seat 450 is arranged on the first ladder 100 and located between the two lock tongues 310, the transfer seat 450 is rotatably provided with a transfer gear 460, the two corresponding active pieces 430 of the lock tongue 310 are symmetrically arranged relative to the axis center of the transfer gear 460, the active piece 430 is provided with a rack 431 corresponding to the transfer gear 460, the rack 431 is engaged with the transfer gear 460, and the racks 431 on the two active pieces 430 are oppositely and parallelly arranged; at least one active piece 430 is connected and matched with the traction rope 410; in this way, when the user pulls the traction rope 410 through the control disc 441 and the pull piece 442, the active piece 430 connected therewith can be moved. Since the rack 431 on the active piece 430 is engaged with the transfer gear 460, the transfer gear 460 will also rotate. The rotation of the transfer gear 460 will drive the rack 431 on the other active piece 430 to move, so that the two lock tongues 310 can move synchronously. This synchronous movement ensures that when the traction rope 410 is pulled, the two lock tongues 310 can be unlocked at the same time, realizing the simplicity and efficiency of operation.

[0053] By setting two lock tongues 310 for locking and positioning, the reliability of locking the relative position of the first ladder 100 and the second ladder 200 is greatly improved. Even in complex and variable use environment, users can rely on this design to ensure the stability and safety of the ladder. By cooperating the transfer gear 460 with the two corresponding racks 431, we realize the function that when the traction rope 410 pulls one of the active pieces 430, the two lock tongues 310 can move synchronously, which not only simplifies the operation process, but also improves the coordination and practicality of the overall structure.

[0054] In some specific embodiments, the transfer seat 450 is provided with a guide groove 451, the long side of the guide groove 451 is parallel to the axis of the telescopic column 311; the active piece 430 is provided with a matching column 432 corresponding to the guide groove 451, the matching column 432 is arranged in the guide groove 451, so as to ensure the stability of the movement of the active piece 430.

[0055] In some specific embodiments, the first ladder 100 is symmetrically provided with a protective member 110 on both sides to avoid damage to the embodiment during use and improve the durability of the embodiment.

[0056] The utility model further provides a vehicle, the vehicle can be divided into SUV, off -road vehicle and motor home etc. Type according to its use scene difference, including vehicle body and the side ladder of preceding embodiment, the first ladder 100 of side ladder is arranged in the side of vehicle body, its vehicle has all the beneficial effects of side ladder, here will not be explained in detail.
