Problems solved by technology

[0002] The traditional propulsion mechanism has a large demand for layout space, but in construction machinery, such as on the vehicle seat, the layout space of the propulsion mechanism is limited, which makes the space arrangement of the propulsion mechanism difficult. The propulsion mechanism installed on the vehicle seat requires The length that can be stretched out is relatively short, resulting in a small support area of ​​the seat leg support for the passenger's leg, which cannot effectively support the passenger's calf, thus failing to meet the comfort requirements of the vehicle seat, resulting in a poorer ride comfort of the vehicle seat. Poor, there is room for improvement

Embodiment Construction

[0025] It should be noted that, in the case of no conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other.

[0026] Refer below Figure 1-Figure 5 A propulsion mechanism 100 according to an embodiment of the present invention is described.

[0027] The propulsion mechanism 100 according to the embodiment of the present invention may include: a base 1 , a driving mechanism 2 and a multi-stage screw telescopic mechanism 3 .

[0028] Such as Figure 1-Figure 5 As shown, the propulsion mechanism 100 of the embodiment of the present invention is suitable for being installed on a vehicle seat so as to be connected between the seat leg support and the vehicle seat body, so as to realize adjustment by pushing the seat leg support to move relative to the vehicle seat body. The supporting positions and angles of the seat leg supports increase the passenger's leg support area, thereby better supporting the passenger's calf,...

Abstract

The invention discloses a propelling mechanism and a vehicle seat. The propelling mechanism comprises a base, a driving mechanism and a multi-stage lead screw telescopic mechanism. The driving mechanism is arranged on the base; the multi-stage lead screw telescopic mechanism is movably arranged on the base in a telescopic mode, the driving mechanism is suitable for driving the multi-stage lead screw telescopic mechanism to move, the multi-stage lead screw telescopic mechanism comprises a plurality of transmission lead screws which are arranged in an internally-sleeved and externally-sleeved mode, every two adjacent transmission lead screws are in threaded fit transmission so that the two adjacent transmission lead screws can move relatively, and the innermost transmission lead screw is constructed as a matching piece connecting part. The overall structure of the propelling mechanism is more compact, so that the occupied arrangement space of the propelling mechanism is smaller, the overall extension length of the propelling mechanism is larger, the propelling mechanism can extend longer in a compact arrangement space, and therefore the propelling mechanism can meet the supporting length requirement for comfort of a seat leg support; and therefore, the seat leg support can better support the shanks of a passenger, so that the riding comfort of the vehicle seat is improved.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a propulsion mechanism and a vehicle seat. Background technique [0002] The traditional propulsion mechanism has a large demand for layout space, but in construction machinery, such as on the vehicle seat, the layout space of the propulsion mechanism is limited, which makes the space arrangement of the propulsion mechanism difficult. The propulsion mechanism installed on the vehicle seat requires The length that can be stretched out is relatively short, resulting in a small support area of ​​the seat leg support for the passenger's leg, which cannot effectively support the passenger's calf, thus failing to meet the comfort requirements of the vehicle seat, resulting in a poorer ride comfort of the vehicle seat. Poor, there is room for improvement. Contents of the invention [0003] In view of this, the present invention aims to propose a propulsion mechanism, the overall str...
