During the telescopic drive process, the lubrication assembly is used to lubricate the screw rod 201 to ensure the transmission effect of the screw rod 201, further facilitating the stable transmission of the drive assembly.

[0023] The lubrication assembly includes a storage groove 401 provided at the upper end of the threaded sleeve 202, the interior of the storage groove 401 is filled with lubricating liquid, a groove 402 is provided inside the storage groove 401, and the interior of the storage groove 401 is connected with the interior of the threaded sleeve 202 under the communication effect of the groove 402, a control assembly for controlling the outflow of lubricating liquid inside the storage groove 401 is provided on the groove 402, and the upper end of the storage groove 401 is threadedly connected with an end cover 403 for blocking the storage groove 401; the control assembly includes a spherical groove 501 provided inside the groove 402, and the interior of the spherical groove 501 is rotatably connected with a rubber ball 502 that abuts against the outer side of the screw rod 201, and the rubber ball 502 A plurality of liquid storage grooves 503 are provided inside; in the process of telescopically driving the steering column body 103 by rotating the screw rod 201, since the rubber ball 502 abuts against the outer side of the screw rod 201, the rubber ball 502 is driven to rotate inside the spherical groove 501 during the rotation of the screw rod 201. During the rotation of the rubber ball 502, when the liquid storage groove 503 on the rubber ball 502 is inside the storage groove 401, the lubricating liquid inside the storage groove 401 flows into the liquid storage groove 503. As the rubber ball 502 continues to rotate, the lubricating liquid inside the liquid storage groove 503 flows out through the groove 402 and falls onto the screw rod 201, thereby lubricating the screw rod 201.
