Embodiment 1

[0029] The vehicle door sill structure is arranged at the bottom of the vehicle door, and can reduce the height of the door sill relative to the ground when the door 2 is opened, so as to facilitate passengers to get on and off the vehicle. The vehicle door sill structure can be used in conjunction with existing car door structures, and is especially suitable for cars with lift-up door structures. The vehicle threshold structure includes a threshold body 3, a sensor and a driving mechanism.

[0030] Specifically, as figure 1 , Figure 4 and Figure 5 As shown, the bottom of the door sill body 3 is hinged to the side wall 1 of the door, and the door sill body 3 can rotate around the hinge axis. In this embodiment, the driving mechanism includes a motor 4 and a rotating shaft 5. The housing of the motor 4 is fixed on the vehicle body, and the rotating shaft 5 is fixed on the inside of the threshold body 3. The axis line of the rotating shaft 5 and the axis center of the hinge...

Embodiment 2

[0034] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the driving mechanism includes a fuel tank, a hydraulic cylinder and an oil pump, and the cylinder body of the hydraulic cylinder is hinged to the door side wall 1 , the free end of the piston rod is hinged with the threshold body 3 . The hydraulic cylinder is connected to the oil tank through the oil pump, and the piston rod of the hydraulic cylinder drives the threshold body 3 to rotate around the hinge.

Embodiment 3

[0036] The technical solution in this embodiment is basically the same as the technical solution in Embodiment 1, the difference is that in this embodiment, the door sill body 3 and the door side wall 1 are connected by guide rail components, and the two sides of the door sill body 3 Sliding heads are fixedly connected respectively, and slide rails are fixed at corresponding positions of the side wall 1 of the car door, and the threshold body 3 can slide along the slide rails. The drive mechanism includes a motor 4 and a cable. The housing of the motor 4 is fixed on the side wall 1 of the car door. A roller is fixed on the main shaft of the motor 4. The middle part of the cable is connected with the roller. Connect the top and bottom. The motor 4 can drive the drag cable to pull the threshold body 3 to slide up and down along the slide rail, so as to adjust the top position of the threshold body 3 .

[0037] The side panel 1 of the vehicle door is provided with a stopper corr...

Abstract

The invention provides a vehicle threshold structure which belongs to the technical field of vehicles and solves the problem that the traditional vehicle threshold height cannot be regulated. The vehicle threshold structure comprises a threshold body which is positioned on the bottom of a vehicle door port of a vehicle; the threshold body and the side periphery of a vehicle door are movably connected; and a driving mechanism capable of driving the top part of the threshold body to descend and ascend relative to a vehicle floor is arranged between the threshold body and the side periphery of the vehicle door. According to the vehicle threshold structure, when the vehicle door is opened, the top part of the threshold body moves downwards so as to bring convenient for passengers to get on and get off the vehicle; the threshold body and the side periphery of the vehicle door are hinged and can rotate around the hinging position; when the vehicle door is opened, the top end of the threshold body comes into contact with ground by overturning, can play a further supporting function on the passengers of getting on and getting off the vehicle and is convenient for disabled people to get on and get off the vehicle; and a sealing ring and a sealing strip are arranged between the threshold body and the side periphery of the vehicle door, therefore the sealing property of a vehicle body is ensured.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and relates to a vehicle door sill, in particular to a reversible vehicle door sill structure. Background technique [0002] The car door of the car can be divided into forward-opening car door, reverse-opening car door, lift-up car door and folding car door according to the function. Folding doors are mainly used in passenger cars, and reverse doors are rarely used because they are not as safe as other doors. [0003] Existing small cars generally adopt the sliding door, which can be closed by the pressure of the airflow even when the car is running, which has higher safety and is convenient for the driver to observe backward when reversing. However, since the forward-opening type car door is turned to the front of the car body when the door is opened, the actual passage space for passengers is less after opening the door, and the threshold on the car body is higher than the ground, so it i...
