Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts, and in particular to an electric slide rail assembly of an automobile armrest box. Background Art

[0002] The armrest box is an automotive accessory located at the rear between the main driver and the co-driver. It mainly provides elbow support for the driver and passengers, allowing the arms to rest effectively. The armrest box also provides the function of storing small items such as drinks and cups.

[0003] With the development of technology and the continuous upgrading of automobiles, especially new energy vehicles, people are pursuing higher and higher comfort. In addition to cup holders and storage functions, armrest boxes have gradually integrated high-tech functions such as wireless charging, car refrigerators, and human-computer interactive touch screens. Since the driver and co-driver seats of the car can move forward and backward, the armrest box also needs to be able to move forward and backward to keep consistent with the driver's seat.

[0004] Traditional armrest boxes mainly convert the rotation of the handle into the horizontal movement of the box along the slide rail assembly by pulling the handle. In order to pursue a larger use space in the car, current cars, especially new energy vehicles, usually equip the seats with long slide rails to make the travel of the driver and co-driver seats longer, which also puts forward higher requirements for the travel of the armrest box. However, due to the coordination and spatial relationship between the various moving components, the lubrication of the slide rail slot and the stability index of the box when moving, the manual slide rail assembly of the traditional car armrest box can no longer meet the above requirements. Utility Model Content

[0005] In order to overcome the shortcomings and deficiencies of the prior art, the utility model provides an electric slide rail assembly which can realize the sliding locking of a vehicle armrest box over a long stroke.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an electric slide rail assembly of an automobile armrest box, comprising an outer slide rail fixedly connected to the vehicle body and an inner slide rail carrying the armrest box; a roller connected to the inner slide rail is arranged in the outer slide rail, and a driving mechanism and a wiring harness connector are arranged on the inner slide rail, and the driving mechanism comprises a screw rod located between the outer slide rail and the inner slide rail, a nut block screwed to the screw rod through a thread, and a retaining frame arranged on the nut block, the retaining frame is connected to the inner slide rail and the inner slide rail connection wiring harness connector is exposed at the top, the outer slide rail is provided with a front supporting plate and a rear supporting plate respectively supporting the front and rear sides of the screw rod, the screw rod is connected to the front supporting plate and the rear supporting plate through a bearing, and then locked by a locking nut, a driving motor and a reduction box are arranged on the front supporting plate or the rear supporting plate in sequence, and the output end of the reduction box is connected to the screw rod.

[0007] Furthermore, the driving motor is parallel to the reduction box and the inner slide rail.

[0008] Furthermore, the driving motor is perpendicular to the reduction box and the inner slide rail.

[0009] The electric slide rail assembly of the vehicle armrest box has guide cavities with top slots symmetrically arranged on the left and right sides of the outer slide rail, and a rolling track extending along the length direction and supporting the roller is arranged on the outer side of the bottom of the guide cavity.

[0010] The electric slide rail assembly of the vehicle armrest box, the outer slide rail also includes a mounting cavity arranged between the two guide cavities for the passage of the wiring harness.

[0011] The electric slide rail assembly of the vehicle armrest box has an inner slide rail formed by connecting a top plate and two left and right side plates, and the roller is installed on the side plates through a wheel axle.

[0012] The electric slide rail assembly of the vehicle armrest box has a roller that is a ball bearing, and auxiliary rollers that are arranged in parallel on the side panels and are located in front of or behind the rollers and are used to adjust the upper and lower gaps between the inner slide rail and the outer slide rail.

[0013] The beneficial effects of the utility model are:

[0014] When in use, the drive motor drives the reduction box and then drives the lead screw to rotate, and the lead screw generates relative motion with the nut block through the thread. Because the lead screw is fixed to the outer slide rail by the front support plate and the rear support plate, the nut block drives the inner slide rail to move back and forth through the retaining frame, thereby outputting the rotational motion of the reduction box as a horizontal linear reciprocating motion, and the inner slide rail moves back and forth along the outer slide rail through the roller to achieve long-stroke movement of the armrest box in the vehicle body. Once the drive motor is turned off, the inner slide rail stops on the outer slide rail. Since the nut block locks the lead screw, the inner slide rail can be accurately locked on the outer slide rail, and it is not limited by the length of the slide rail.

[0015] The utility model converts the rotation of the drive motor into the linear motion of the inner slide rail on the outer slide rail through the cooperation of the lead screw nut, thereby starting the drive switch of the drive motor, so that the forward / reverse rotation can operate the forward / backward movement of the armrest box. The texture effect and accuracy of the whole control process are better. The control switch of the drive motor can be set anywhere on the driver and co-pilot seats, which greatly improves the human-machine space experience effect. BRIEF DESCRIPTION OF THE DRAWINGS
