Description

Latch mechanism for vehicles

[0001] The present invention relates to a latch mechanism for a vehicle capable of locking a striker.

[0002] The vehicle may be provided with moving parts for the vehicle, such as doors, hoods, deck lids, trunk lids, lift gates, displays, etc.

[0003] A latch is a fastener that supports a clasp, fastener, or jig plate, and a vehicle may be equipped with a latch that can lock a moving part.

[0004] A moving part for a vehicle and a body or cockpit may be equipped with a striker and a latch, and the closing position of the moving part may be maintained by engaging the striker and latch at a position where the moving part is locked.

[0005] An example of a striker and latch is a striker buffer device of a vehicle hood latch disclosed in Republic of Korea Utility Model Publication No. 20-1999-0007107 U (published on February 25, 1999).

[0006] A striker buffer device for a hood latch for a vehicle comprises a plate installed on a body, a striker provided on the central part of the inner side of the hood, a main locker formed to form an insertion groove in which the striker is engaged, and installed so that the striker is raised a predetermined distance by being elasticized by a return spring and pivoting by its restoring force, an auxiliary locker formed as a handle and doubly opening and closing the striker, and a pole selectively engaging the main locker and having a release cable connected thereto, wherein an elastic member for absorbing shock by elastic force when in contact with the striker is formed within the plate of the latch, and a fixing member for fixing the elastic member within the plate are configured.

[0007] The present embodiment provides a vehicle latch mechanism capable of minimizing noise.

[0008] A vehicle latch mechanism according to the present embodiment comprises a latch that is rotated by a striker and locks the striker in a locked position; a lever that locks or releases the latch; and a drive module that rotates the lever to a latch locking angle after the latch is rotated to a locking angle that locks the striker in the locked position, wherein the lever can be out of contact with the latch when at the latch locking angle.

[0009] The drive module may include a cam gear connected to the lever; a worm gear meshed with the cam gear; and a drive source for rotating the worm gear.

[0010] The vehicle latch mechanism may further include a housing having a receiving space formed therein for receiving the latch, lever, cam gear and worm gear.

[0011] The vehicle latch mechanism may further include a first spring installed between the housing and the latch and a second spring installed between the housing and the lever.

[0012] A fastening body to which a driving source is fastened can be formed on the outer surface of the housing.

[0013] A through hole may be formed in the housing through which the rotational shaft of the drive source passes.

[0014] The housing may include a bottom plate; and a cover plate coupled to the bottom plate.

[0015] The vehicle latch mechanism may further include a worm gear supporter disposed in the housing and supporting the worm gear.

[0016] The drive module may further include a detection unit that detects the position of the striker or the angle of the latch; and a control board that controls the drive source according to the detection result of the detection unit.

[0017] The drive module may further include a timer.

[0018] A vehicle latch mechanism may further include a first sensor for detecting a latch release angle of a lever; and a second sensor for detecting a latch engagement angle of the lever.

[0019] The first sensor and the second sensor may be placed on the lever-facing surface of the control board facing the lever.

[0020] The control board can control the driving source to the locking mode when the striker is detected by the sensor unit to be in the locking position or the latch is at the locking angle, and after the time set by the timer has elapsed.

[0021] Either the lever or the cam gear may have a protrusion.

[0022] The lever and the other of the cam gears may have a cam path formed thereon, which is guided by a projection.

[0023] The lever may be metal and the cam gear may be synthetic resin.

[0024] The lug may protrude from one side of the lever, and the cam pass may penetrate the cap gear.

[0025] The cam path may include a first region spaced apart from the center of rotation of the cam gear by a first distance; and a second region extending from the first region and spaced apart from the center of rotation of the cam gear by a distance shorter than the first distance.

[0026] According to this embodiment, when the striker is in the locking position and the lever is at the latch engagement angle, the lever does not contact the latch, so that noise that may occur when the striker is locked can be minimized.

[0027] In addition, the driving source of the driving module for rotating the lever is placed outside the housing, making it easy to service the driving source.

[0028] In addition, since the worm gear is supported by the worm gear supporter arranged in the housing, the sagging of the worm gear can be minimized, the worm gear can reliably rotate the cam gear, and malfunction of the cam gear can be minimized.

[0029] In addition, since the striker is detected to be in the locking position or the latch is at the locking angle by the detection unit and the driving force is controlled to the locking mode after the time set by the timer has elapsed, collision between the lever and the latch or noise caused by the collision can be minimized, and the lever can be easily rotated to the latch locking angle.

[0030] In addition, the projection protrudes from one side of the metal lever, and the cam pass penetrates the cap gear made of synthetic resin, making it easy to form the projection and cam pass.

[0065] The striker (4) positioned at the locking position (P1) can be raised, and if the lever (6) is at an angle that cannot restrict the latch (5), the striker (4) can be raised without being locked to the latch (5).

[0066] When the striker (4) rises, the latch (5) can be rotated to an unlocking angle (θ2) by the striker (4).

[0067] The unlocking angle (θ2) can be defined as the angle of the latch (5) when the latch (5) does not lock the striker (4).

[0068] When the latch (5) is at the unlocking angle (θ2), the striker (4) may not be bound to the latch (5).

[0069] That is, the striker (4) can be lowered to rotate the latch (5) to a locking angle (θ1), and when the lever (6) does not interfere with the rotation of the latch (5), it can be rotated to an unlocking angle (θ2) by the striker (4).

[0070] The latch (5) may be formed with a striker groove (51) into which a portion of the striker (4) may be inserted. The striker groove (51) may be sunken into the outer periphery of the latch (5).

[0077] The lever (6) can engage or disengage the latch (5).

[0078] The lever (6) can be rotated to a latch engagement angle (θ3) or a latch release angle (θ4).

[0079] The latch restraint angle (θ3) can be defined as the angle of the lever (6) when the lever (6) restricts the restoration of the latch (5).

[0080] The lever (6) may be in a non-contact state with the latch (5) when the latch engagement angle (θ3). The lever (6) may be spaced apart from the latch (5) when the latch engagement angle (θ3). The lever (6) may be spaced apart from the latch (5) by a set distance when the latch engagement angle (θ3). An example of the set distance may be 0.5 mm.

[0081] When the lever (6) is at the latch locking angle (θ3), the latch (5) can be locked by the lever (6), and even if the striker (4) is raised, the latch (5) may be blocked by the lever (6) and may not rotate further, and the latch (5) can maintain the striker (4) in the locking position (P1).

[0082] The lever (6) can be separated from the latch (5) when the lever (6) is at the latch release angle (θ4). When the lever (6) is at the latch release angle (θ4), the latch (5) is not bound to the lever (6) and can be rotated at the locking release angle (θ2).

[0083] The lever (6) may include a stopper (61) that can limit arbitrary rotation of the latch (5). The stopper (61) may have a shape that protrudes from the lever (6), and when the lever (6) is at the latch locking angle (θ3), the stopper (61) may face the latch (5).

[0084] A protrusion (62) may be formed on the lever (6). The protrusion (62) may protrude from one of the two sides of the lever (6).

[0089] As illustrated in Fig. 5, when the latch (5) is at a locking angle (θ1) and the lever (6) is at a latch locking angle (θ3), the periphery (52) of the striker groove (51) of the latch (5) may face the stopper (61), and a setting gap (T) may be formed between the periphery (52) of the striker groove (51) and the stopper (61). An example of the setting gap (T) may be 0.5 mm.

[0090] A vehicle latch mechanism may include a drive module (7) capable of rotating a lever (6).

[0091] The drive module (7) can rotate the lever (6) at a latch engagement angle (θ3). The drive module (7) can rotate the lever (6) at a latch release angle (θ4).

[0092] While the latch (5) is rotated from the unlocking angle (θ2) to the locking angle (θ1), the lever (6) can maintain the latch release angle (θ4), and when the latch (5) is completely rotated to the locking angle (θ1), the lever (6) can be rotated to the latch locking angle (θ3).

[0093] That is, after the latch (5) has completed rotation at the locking angle (θ1), it is desirable for the driving module (7) to rotate the lever (6) at the latch restraining angle (θ3).
