Abstract: This disclosure is directed to an electric support rod having a driving assembly, an actuating assembly, and a bearing. The driving assembly has a first outer tube and a driving unit in the first outer tube. An internal thread is configured in the first outer tube. The actuating assembly has a second outer tube and a transmission screw rod in the second outer tube. Multiple elastic arms axially are extended from the second outer tube and arranged spacedly around the transmission screw rod. Each elastic arm has an outer thread structure and a hook portion. The second outer tube is inserted in the first outer tube, the internal thread is screwed with the outer thread structure. One end of the transmission screw rod protrudes from the second outer tube to engage the driving unit. The bearing sheathes the transmission screw rod and the hook portion latches the bearing.

Abstract: A silenced guide rail includes a guide rail body, a guide block, and a slideway. The guide rail body includes a beam piece, and the beam piece includes an abutting end. The guide block is connected to one end of the guide rail body, and the guide block includes a docking strip. The docking strip includes a corresponding abutting end corresponding to the abutting end. The abutting end includes a short side and a bevel. A shape of the corresponding abutting end corresponds to a shape formed by the short side and the bevel. The slideway is formed on the beam piece and the docking strip. Therefore, the present disclosure reduces an abnormal noise generated when a guide post passes through a connection between the guide rail body and the guide block, and an effect of eliminating all or most of the abnormal noise may be achieved.

Abstract: A window glass gripping device which is assembled on a rail with a linking element includes: a glass gripper, slidably connected on the rail; a limiter, secured on the linking element; and an adjusting bolt, screwed to the glass gripper, having a limited portion. The limiter is assembled to correspond to the limited portion for limiting a position of the adjusting bolt.

Abstract: A cable length automatic adjustment device for a vehicle window lifter includes a housing (1) having a hollow internal, a cable axial shaft (2) arranged inside the housing (1) and an adjusting member (3). The cable axial shaft (2) includes an axle base (20), an axial shaft (21) extended from the axle base (20) and a first elastic member (22) abutted between the axle base (20) and an inner wall of the housing (1). The adjusting member (3) includes a slotted base (30), positioning pieces (32) moveably attached onto the slotted base (30) and a second elastic member (33) abutted between the axle base (20) and the positioning pieces (32). The axial shaft (21) includes indented positioning portions (210), and the positioning pieces (32) include corresponding engagement portions (320). The positioning pieces (32) are clamped onto the positioning portions (210) of the axial shaft (21) with the engagement portions (320).

Abstract: A retractable speaker structure for use in a vehicle is provided. The retractable speaker structure includes: a case formed with a chamber; a driving member installed in the chamber and including a stepping motor and a transmission shaft connected to the stepping motor; a retracting mechanism disposed in the chamber and including a screw rod and a retractable rod fitted with the screw rod. The screw rod is driven by the transmission shaft to rotate, thereby enabling the retractable rod to perform a protruding/retracting movement relative to the screw rod; and a speaker secured at an end section of the retractable rod and moved with the retractable rod. Accordingly, the retractable speaker structure is able to be adjusted for being protruded or retracted according to the actual needs, thereby effectively simplifying components and lowering production cost.
