Abstract

The present disclosure provides a motor vehicle latch, comprising: a housing defining an internal space; a locking mechanism accommodated in the internal space; an electric drive device accommodated in the internal space and including a motor and a power transmission device, the power transmission device including a gear and an actuating part capable of actuating the locking mechanism; a detection element accommodated in the internal space for detecting the state of the locking mechanism; an external connection terminal located outside the internal space of the housing; and an internal connection terminal located inside the internal space, wherein the detection element and the internal connection terminal are respectively integrally formed with the housing. According to the above solution, an electrical component such as the detection element, a connector connected to other electric components such as the motor, etc. are directly formed in the body of the housing, thereby greatly reducing the number of components to be mounted and reducing the assembly difficulty.

Abstract

The invention relates to a motor vehicle latch, and in particular a motor vehicle door latch, which is equipped with an electromotive opening drive (5, 6) for a locking mechanism (1, 2) consisting substantially of a catch (1) and a pawl (2). In addition, a drive wheel (6) of the electromotive drive (5, 6) works on a release lever (3) to open the locking mechanism (1, 2). According to the invention, a blocking lever (7) assigned to the release lever (3) is provided, which blocking lever (7) is transferred from a blocking position to a release position for the release lever (3) by the opening catch (1).

Abstract

The subject matter of the invention is a locking device for an electrical plug-in connection and, in particular, a locking actuator for a charging port (1) of an electric or hybrid motor vehicle. For this purpose, in its fundamental construction, the device has an electric motor (5), a downstream gear mechanism (6, 7, 8) and a locking element (3) which is connected to the latter. The locking element (3) interacts indirectly or directly with an output-side toothed wheel (8) of the gear mechanism (6, 7, 8), and defines a locking direction (VR). According to the invention, at least the output-side toothed wheel (8) and the locking element (3) are arranged in a housing free region (9) which permits a mutual interaction with different locking directions (VR).

Abstract

A latch for a front hood of a vehicle is provided. The latch comprising a housing (1), a catch (2) and a pawl (3) rotatably supported on the housing (1), and a torsion spring (4) fixed relative to the housing and comprising a first leg (41). The pawl (3) is configured to lock the catch (2) which locks a striker (5). The first leg (41) and the catch (2) are configured to abut against the striker (5) at opposite sides in a locked state of the striker. A free end of the first leg (41) is inserted into a receiving slot (6) formed in the housing (1) and is capable of sliding under the guidance of the receiving slot (6). Since the torsion spring and the catch clamp the striker at its two sides, noise generated by wobbling of the striker within the catch is eliminated. Furthermore, as the movement of the first leg of the torsion spring can be guided by the receiving slot of the housing, wobbling of the first leg of the torsion spring is prevented, resulting in more stable and reliable locking and unlocking processes.

Abstract

A front hood latch of a vehicle is provided. The latch includes a housing (1) fixed to a vehicle body, and a catch (2), a pawl (3) and an auxiliary catch (4) which are rotatably supported on the housing (1). The catch (2) is configured to lock a striker, and the pawl (3) is configured to lock the catch (2). The auxiliary catch (4) and the catch (2) are configured to abut against the striker (5) at opposite sides in a locked state of the striker. The latch further includes a spacer (6) provided between the auxiliary catch (4) and the catch (2). Noise generated by wobbling of the striker within the catch can be avoided, non-smooth relative movement between the catch and the auxiliary catch, caused by machining errors, or by entry of foreign contaminants between them, can be prevented, and wear of the auxiliary catch and the catch can be reduced.
