Description

Technical Field

[0001] The utility model relates to the technical field of vehicle step plates, in particular to a vehicle step plate structure. Background Art

[0002] With the continuous development of society and the continuous improvement of people's quality of life, motor vehicles have gradually become a necessity in social activities. Because of some special uses, such as increasing the vehicle's passability, motor vehicles include some models with higher chassis. The higher chassis of motor vehicles brings some troubles to users with relatively short height when getting on and off the vehicle.

[0003] Some motor vehicles will weld a step plate under the door of the motor vehicle, so that the user can step on it to gain leverage when entering and exiting the vehicle. However, the step plate fixed under the door affects the appearance of the vehicle. For this reason, some step plates are designed as a pull-out structure. When needed, the user pulls out the step plate, and after use, pushes the step plate into the frame in time. Although this structure beautifies the appearance of the vehicle, the manually pulled step plate increases the boarding process for the user, which is inconvenient to use. Moreover, when the user steps on it, it is very likely that the step plate will slide obliquely due to the stepping direction not perpendicular to the step plate, which affects the stability of the user's center of gravity when entering and exiting the vehicle, and there are certain safety hazards. For this reason, a boarding step plate structure is proposed. Summary of the invention

[0004] The utility model aims to provide a step plate structure for boarding a vehicle to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A step plate structure for boarding a vehicle, comprising a vehicle door and a flip step plate, wherein the top and bottom ends of the vehicle door are both provided with a vehicle door hinge base, and the vehicle door is connected to the vehicle door hinge base through a vehicle door hinge, and is characterized in that: a driving gear is provided at the bottom end of the vehicle door hinge;

[0007] The bottom end of the door is provided with a guide pulley base and a pre-tightening pulley base;

[0008] The pre-tightening pulley base is provided with a pre-tightening pulley, and the pre-tightening pulley is connected to the driving gear;

[0009] The flip tread is arranged on the vehicle body, the flip tread is connected to a cable, and the cable is connected to a pre-tightening pulley;

[0010] The guide pulley base is provided with a guide pulley for changing the direction of the cable.

[0011] Furthermore, a driven gear is provided at the top end of the preload pulley.

[0012] Furthermore, the driven gear is meshed with the driving gear.

[0013] Furthermore, the flip step plate is connected to the vehicle body via a hinge.

[0014] Furthermore, a spring is provided inside the flip tread.

[0015] Furthermore, the flip tread is provided with a cable fixing bracket for connecting the cable.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] The mechanism has the advantages of simple structure, low cost, beautiful appearance and convenient use. It is suitable for vehicles with high chassis and inconvenient getting on and off the vehicle. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] Example 1, please refer to Figure 1-6 , the utility model provides a technical solution:

[0027] A step plate structure for boarding a vehicle comprises a vehicle door and a flip step plate 8. A vehicle door hinge base 1 is arranged at the top and bottom of the vehicle door. The vehicle door is connected to the vehicle door hinge base 1 through a vehicle door hinge 4. A driving gear 5 (such as Figure 2 );

[0028] A guide pulley base 2 and a preload pulley base 3 are arranged at the bottom of the door (such as Figure 1 );

[0029] A preload pulley 7 is arranged on the preload pulley base 3, and the preload pulley 7 is connected to the driving gear 5 (such as Figure 3 );

[0030] The flip step plate 8 is arranged on the vehicle body, and the flip step plate 8 is connected to the cable, and the cable is connected to the preload pulley 7 (such as Figure 5 );

[0031] The guide pulley base 2 is provided with a guide pulley 21 (such as Figure 4 ).

[0032] like Figure 3 As shown: a driven gear 6 is arranged at the top of the preload pulley 7 to facilitate the engagement of the driven gear 6 with the driving gear 5.

[0033] like Figure 5 As shown: the flip step plate 8 is connected to the vehicle body via a hinge.

[0034] like Figure 5 Shown: the spring is installed inside the flip step plate 8.

[0035] like Figure 5 As shown: the flip tread plate 8 is provided with a cable fixing bracket 9 for connecting the cable.

[0036] Working principle:

[0037] The door is mounted on the door hinge base 1 of the vehicle body through the door hinge 4 axis, and can rotate around the hinge. A driving gear 5 is arranged below it, which rotates with the door ( Figure 2 ).

[0038] The preload pulley 7 is mounted on the preload pulley base 3 of the vehicle body, and the driven gear 6 at the upper end cooperates with the driving gear 5 at the lower end of the door hinge 4 and is driven by it ( Figure 3 ).

[0039] The guide pulley 21 is installed on the guide pulley base 2 of the vehicle body and is used to change the direction of the cable ( Figure 4 ).

[0040] The flip tread plate 8 is mounted on the vehicle body through a hinge, and a spring is arranged inside. Under the drive of its own gravity and the spring, the flip tread plate always maintains an outward flipping force. A cable fixing bracket 9 is arranged on the flip tread plate 8 to fix the cable on the preload pulley 7 ( Figure 5 ).

[0041] When the door is opened, the driving gear 5 of the door hinge shaft 4 drives the driven gear 6 of the preload pulley 7, and the preload pulley 7 rotates accordingly, loosening the cable, and the flip step 8 flips downward under its own gravity and the drive of the spring ( Figure 6 ).

[0042] When the door is closed, the driving gear 5 of the door hinge shaft drives the driven gear 6 of the preload pulley 7, and the preload pulley 7 rotates accordingly, tightening the cable, and the turning step plate 8 is turned upward under the drive of the cable ( Figure 7 ).

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
