Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts, and particularly relates to an automobile side ladder. Background Art

[0002] With the continuous expansion of automobile application scenarios, side ladders will be installed on caravans or off-road vehicles for practicality. The main function of the side ladder is to enable the operator to easily take and put items on the roof luggage rack. In the prior art, there are many automobile side ladder technologies. For example, patent CN202222599416.2 provides a side ladder installation assembly and vehicle, which aims to solve the problem that the side ladder seriously blocks the side windows when not in use, affecting the passenger's field of vision. The position of the side ladder can be adjusted according to the actual placement of the luggage, thereby improving the convenience of taking and putting luggage.

[0003] Vehicle side ladders are generally required to be aesthetically pleasing and reliable. Especially for small and micro off-road vehicles, they require a simple structural design that ensures applicability and secure fixation. This is especially important during driving, as they avoid vehicle vibrations that can cause noise between the side ladder and the luggage rack. Furthermore, to improve the reliability of side ladders during use, some manufacturers use destructive installation methods, such as adding fixing screws to the vehicle. However, these methods can damage the vehicle structure, potentially causing water leakage and corrosion, and are unsightly and require high repair costs after disassembly. Utility Model Content

[0004] The utility model aims to provide a car side ladder, which solves the problems of vibration noise caused by unstable installation and avoids defects that damage the installation by arranging a base plywood on the side ladder, thereby improving the applicability of the car side ladder to off-road vehicles.

[0005] Technical solution: A vehicle side ladder includes a ladder assembly, the ladder assembly includes ladder beams and cross beams, the upper end of the ladder assembly is provided with a roof connection structure, the lower end is provided with a bracket seat, and a base bonding plate is provided through the bracket seat, and the base bonding plate is used to bond with the vehicle body to achieve stability;

[0006] The roof connection structure includes an upper fixed base plate and an installation cover plate. The fixed base plate and the installation cover plate wrap the ladder beam. The end of the installation cover plate includes a U-shaped slot for engaging and fixing with the round tube of the roof frame.

[0007] Furthermore, a first adjustment hole and a second adjustment hole are arranged in parallel on the bracket seat, the aperture of the second adjustment hole is smaller than that of the first adjustment hole, and the first adjustment hole and the second adjustment hole are connected to the base fitting plate through self-locking bolts, and the angle of the base fitting plate is adjusted by fixing the self-locking bolts in the first adjustment hole and the second adjustment hole.

[0008] Furthermore, the first adjustment hole and the second adjustment hole are configured as oblong holes or waist-shaped holes.

[0009] In the ladder assembly, both ends of the crossbeam are fixed to the ladder beam via sleeves;

[0010] The ladder beams include positioning holes at different positions for adjusting the intervals between adjacent beams.

[0011] Furthermore, the upper end fixing base plate and the mounting cover plate in the roof connection structure are fixed by bolts and wrapped around the outer periphery of the ladder beam.

[0012] The upper end fixed base plate and the mounting cover plate in the vehicle roof connection structure include a traveling structure arranged with the vehicle roof, and the traveling structure includes a curved portion.

[0013] The portion where the upper fixed base plate and the vehicle body are in contact with each other includes a rubber layer or elastic rubber material.

[0014] The back of the base laminating plate is affixed with a sticky rubber pad to achieve adhesion to the vehicle body.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This new utility model utilizes an adjustable base plate design, combined with a sticky rubber pad, to achieve non-destructive installation on the vehicle body's sheet metal surface, effectively reducing the shaking noise of the side ladder during driving. This design changes the existing side ladder's point contact bolt design, increasing the load-bearing area and ensuring a more balanced load range on the vehicle body during climbing and use, minimizing damage to the vehicle body. Furthermore, this new side ladder features strong adjustability, a U-shaped slot protection frame for the roof mounting structure, and a detachable main ladder for easy transportation and aesthetically pleasing installation.

DETAILED DESCRIPTION

[0022] In order to better explain the technical solution of this utility model, Figure 1-4 The structure and use method of the utility model are further explained:

[0023] Please see the attached Figure 1-4 A car side ladder can be made of aluminum material, including a ladder beam 1, a cross beam 2, a roof connecting structure and a base plywood 11. The ladder beam 1 is a U-shaped aluminum circular tube structure with one or more cross beams 2 in the middle. Long circular holes are symmetrically arranged on the ladder beam 1. The fixed position of the cross beam 2 can be adjusted up and down within a certain range, and then a sleeve 8 is added at the connection, which can achieve the beneficial effects of beauty and increasing strength.

[0024] The roof connection consists of a mounting cover plate 3 and an upper fixed base plate 5, both of which are bolted to the roof platform. Importantly, a U-shaped slot 4 is provided at one end of the mounting cover plate 3 to secure the roof bracket. The curved roof connection structure perfectly matches the curvature of the vehicle body and roof. The upper and lower portions of the bend are provided with first and second mounting bolts 6 and 7. The first mounting bolts 6 securely connect the mounting cover plate to the base plate 5 and are located in multiple locations. The second mounting bolts 7 secure the lower portion of the bend and connect it to the ladder beam 1. After disassembly, the roof connection structure and the ladder beam 1 form a separate structure, facilitating transportation.

[0025] Importantly, a bracket seat 9 is provided at the bottom cross-tube connection of the ladder beam 1, which is symmetrically distributed. On the bracket seat 9, there are two parallel first adjustment holes 12 and second adjustment holes 13, both of which are oblong in shape, and the circular diameter of the first adjustment hole 12 is larger than the circular diameter of the second adjustment hole 13. When the base bonding plate 11 is installed, it is fixed in the adjustment hole by a self-locking bolt 10. Due to the difference in the circular diameter of the two adjustment holes, the base bonding plate 11 can be appropriately adjusted in angle within a limited range, including height adjustment of the base bonding plate 11, to ensure fit with the vehicle body. In order to protect the vehicle body sheet metal and avoid direct collision damage between the side ladder and the vehicle body caused by vibration during driving, a two-way 3M adhesive rubber pad is provided on the back of the base bonding plate 11.

[0026] By adjusting the angle of the base bonding plate 11, it is ensured that it can match and fit with the vehicle body, changing the lossy installation method such as the need to punch holes at the connection between the side ladder and the vehicle body in the existing technology, and also changing the traditional point contact to surface contact, thereby improving the supporting strength of the side ladder on the vehicle body, protecting the vehicle body sheet metal and improving the support, and having the characteristics of beautiful appearance and high reliability.
