Description

Electric side pedal and vehicle

Technical Field

The utility model relates to a vehicle parts technical field, in particular to electronic side is stepped on. The utility model discloses still relate to the vehicle of installing this electronic side and stepping on.

Background

The electric side pedal is an automatic telescopic automobile pedal, provides convenient service for getting on and off high chassis automobiles (mainly commercial vehicles, SUVs and off-road vehicles), and mainly comprises a driving system, a controller, a connecting rod mechanism and a pedal body. The pedal body is generally installed on an automobile chassis through a link mechanism, and when a passenger needs to get on or off the automobile, the controller automatically controls the extension and retraction of the pedal through sensing the state of an automobile door and other signals of the whole automobile, so that the comfort and the safety of stepping are achieved. Because the electric pedal is mainly matched with the models with higher chassis such as commercial vehicles, SUVs, off-road vehicles and the like, many customers have higher requirements on the aspects of overall exquisite perception, reliability, durability, overall noise performance and the like of the electric pedal.

The existing electric side pedal basically adopts a link mechanism as a telescopic movable part, and the link mechanism realizes rotation and movement through a pin shaft and a bearing. The existing connecting rod mechanism pin shaft on the electric side pedal is arranged on an inner connecting plate and an outer connecting plate in an interference fit or screw fixing mode, and the bearing is arranged on an underframe and a support in an interference fit mode, so that the bearing is exposed outside and is in direct contact with the external severe environment (silt, corrosive substances and the like).

The current bearing installation mode can lead the bearing to be directly exposed outside, so that the bearing is directly contacted with the external severe environment (silt, corrosive substances and the like). Over time, the bearings can be severely rusted, and the inner rings of the bearings can accumulate a great deal of fine dust and gravel, which can cause the connecting rods to generate abnormal sound unacceptable to customers during the unfolding and folding processes. The corrosion of the bearing and the accumulation of dust and gravel on the inner ring of the bearing not only greatly reduce the performance and service life of the pedal product, but also cause complaints and claims of customers and seriously affect the brand value.

Although some domestic manufacturers replace metal bearings with plastic bearings or rubber bearings, the problem of abnormal sound caused by silt accumulation still cannot be solved, and more seriously, the plastic bearings or the rubber bearings still face the problems of weather-resistant and aging-resistant service life and insufficient bearing capacity, so that the influence caused by the abnormal sound is worse.

In addition, the clearance undersize between chassis and the outer connecting plate, when the footboard expandes, there is the stone chassis and outer connecting plate clearance department, packs up the in-process at the footboard, and chassis and outer connecting plate can extrude the stone, and at this moment, the stone can step on to electronic side and cause the harm, produces the abnormal sound, triggers electronic side and steps on and prevent pressing from both sides the function, arouses even that electronic side is stepped on unnecessary puzzlement such as not moving.

Also as a preferred embodiment of this embodiment, the dust-proof member of this embodiment comprises a bowl-shaped plug 8 press-fitted into the rotation hole 100. Of course, it will be appreciated that instead of using a bowl plug 8, the dust guard may be a baffle that blocks the rotation bore, thus also providing dust protection to the bearing assembly 6 within the rotation bore 100.

In a specific assembling sequence, the second bearing 62 is firstly pressed into the rotary hole 100, then the O-ring 7 is embedded into the mounting groove 200, then the first bearing 61 is pressed into the rotary hole 100, and the first bearing 61 and the second bearing 62 are enabled to press the O-ring 7, so that the O-ring 7 is better fixed, when the shaft end is mounted into the bearing hole, the O-ring 7 can be prevented from falling off, and the O-ring 7 can be enabled to be clamped on the outer peripheral surface of the connecting shaft 5.

In addition, in the embodiment, the electric side pedal further comprises a driving device, the driving device is used for driving the connecting rod mechanism to move, and the pedal can be unfolded and folded along with the movement of the connecting rod mechanism. In specific implementation, the driving device usually employs a motor, and an output shaft of the motor is in transmission connection with one of the connecting shafts 5 in the link mechanism to drive the connecting shaft 5 to rotate, so as to drive the link mechanism to move.

For the purpose of facilitating the arrangement and mounting of the drive means, the drive means is preferably arranged on the stationary bracket 1. Because the pedal usually adopts a long strip plate-shaped structure, in order to improve the connecting effect of the pedal and the vehicle body, the connecting rod mechanisms between the pedal and the vehicle body are a plurality of connecting rod mechanisms which are arranged at intervals along the length direction of the pedal. The link mechanism with the driving means is called a driving bracket, and the other link mechanism without the driving means is called a driven bracket.

In the present embodiment, as shown in fig. 4 and 6, a buffer 9 is provided between the first link 3 and the second link 4 to reduce the collision and impact of the first link 3 and the second link 4 when the first link 3 and the second link 4 are closed, and to avoid the occurrence of collision noise.
