Description

Technical field

[0001] The present invention relates to a motor-driven door lock for a vehicle. Background of the invention

[0002] In general, a motor-driven door lock is used for a vehicle to lock and unlock a door to a vehicle body using a motor for the convenience of a user.

[0003] In addition, an inner handle and an outer handle are installed to allow the user to grasp the vehicle door and to operate the vehicle door easily, and a switch or the like is provided on the vehicle door to lock or release the motor-driven door lock.

[0004] However, with the conventional, motor-driven locking structure, an external handle is required to open the vehicle door from the outside, so that a passenger / occupant can simply grab the vehicle door with their hand, and the external handle is attached to an outer panel of the vehicle door to protrude in a width direction of the vehicle to the outside, or to be incorporated into the outer panel, which degrades the external appearance of the vehicle and causes driving resistance.

[0005] The information disclosed above in this section “Background of the Invention” serves only to provide a better understanding of the general background of the invention and may therefore contain information that does not constitute prior art already known to the person skilled in the art.

[0006] For example, DE10 2008 035 183 A1 discloses a motor-driven door lock for a vehicle which has a vehicle body, wherein the motor-driven door lock comprises: a latch part which is engaged with a locking bar attached to the vehicle body to lock a door of the vehicle, or which is released from the locking bar so that the door can be opened from the vehicle body; a door locking and release part which has a main motor and is configured to apply a torque to the latch part by the main motor and to allow the latch part to be locked to or released from the locking bar; and a release part which has an auxiliary motor and is configured to apply a torque to the latch part so that the door of the vehicle pops out from the vehicle body.The latch assembly comprises: a latch having a locking groove that engages or is separate from the latch bolt attached to the vehicle body, the latch being installed to be rotatable, and a claw being installed to be rotatable, the claw being configured to be in close contact with the latch to restrict its rotation, or to be separate from the latch to allow the latch to rotate freely. The door locking and release assembly comprises: the main motor having a first drive gear, a first driven gear engaging with the first drive gear, and a claw release lever coupled to the claw. Explanation of the invention

[0007] The present invention relates to a motor-driven door lock for a vehicle (for example, a motor vehicle). Particular embodiments of the present invention relate to a motor-driven door lock for a vehicle in which a vehicle door can protrude from the vehicle body (e.g., towards the outside of the vehicle) after the vehicle door has been released from the vehicle body.

[0008] Embodiments can provide a motor-driven door lock for a vehicle which is able to improve the appearance and marketability of the vehicle, as it is not necessary to provide a separate gripping mechanism, such as an external handle, by allowing the vehicle door to pop out or protrude from the vehicle body when the vehicle door is opened, so that a passenger / occupant can simply open the popped-out or protruding vehicle door by hand.

[0009] According to the invention, a motor-driven door lock for a vehicle with the features of claim 1, a motor-driven door lock for a vehicle with the features of claim 2, and a vehicle with such a motor-driven door lock with the features of claim 5 are provided. Further embodiments of the motor-driven door locks are described in the dependent claims.

[0010] That is, a motor-driven door lock for a vehicle according to an exemplary embodiment of the present invention comprises: a latch part which is caught on a locking bar attached to the vehicle to lock the vehicle door to or on a vehicle body, or which is released by the locking bar so that the door can be opened from the vehicle body; a door locking and release part which has a main motor and applies a torque to the latch part by the main motor to allow the latch part to be locked to or released from the locking bar; and a protruding part which has an auxiliary motor and applies a torque to the latch part so that the vehicle door protrudes from or onward from the vehicle body.

[0011] The latch part has a latch (e.g., a locking latch) which has a locking groove in which the locking bar, which is attached to the vehicle body, is caught or separated from it and which is installed to be rotatable, and a claw (e.g., a locking claw) which is installed to be rotatable and which is in close contact with the latch to limit the rotation of the latch, or is separated from the latch to allow the latch to rotate freely.

[0012] The door locking and release assembly comprises the main motor (e.g., an electric motor) which is rotatable in the clockwise and counterclockwise direction (e.g., a drive shaft thereof) and has a first drive gear, a first driven gear which engages with the drive gear, a claw release lever which is coupled to the claw to be rotatable as a single unit, and an actuating lever which engages with the first driven gear and receives a torque from the first driven gear to rotate the claw release lever.

[0013] Furthermore, the protruding part has an auxiliary motor (for example, an electric motor) which has a second drive gear, a second driven gear which engages with the second drive gear, and a third driven gear which engages with the second driven gear and simultaneously engages with a claw gear, or the two seat projections on the claw release lever are formed and a pressure projection, which sits on or at the seat projections and presses and rotates the claw release lever, is provided on the actuating lever.

[0014] A door locking control device, which detects the actuation of a handle or button installed on the vehicle door and sends an actuation signal to the auxiliary motor, may also be provided. The door locking control device can send an actuation signal to the auxiliary motor after the main motor has been actuated.

[0015] In accordance with the motor-driven door locking mechanism for a vehicle according to an exemplary embodiment of the present invention, since a door for a vehicle can be locked to a vehicle body in a stable or secure manner using a main motor and the locked door can be easily released from the vehicle body, a user can conveniently use a door of the vehicle.

[0016] Once the vehicle door is released from the vehicle body, it springs forward from the vehicle body and is swung towards the user using the auxiliary motor, allowing the user to hold the popped-out door and open it. This reduces the number of parts and weight, and improves the vehicle's appearance and marketability by eliminating the need for a separate mechanism or structure, such as a conventional exterior handle.

Detailed description

[0018] The present invention is described in detail below with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.

[0019] As is clear to those skilled in the art, the described embodiments can be modified in numerous different ways without deviating from the scope of the present invention.

[0020] The drawings and description are to be considered illustrative and not limiting. The same reference symbols denote the same elements throughout the description.

[0021] Since the sizes and thicknesses of each component shown in the drawings are arbitrarily represented for the convenience of description, the present invention is not limited to the sizes and thicknesses of each component shown, and one thickness has been enlarged and shown to clearly indicate numerous parts and areas.

[0022] In the following description, component names are subdivided into "first", "second", and the like, since the component names are the same, and the order of these is not particularly restricted.

[0023] Throughout the description, unless explicitly stated otherwise, the term "show" and variations thereof, such as "showing", are to be understood as implying the addition of the specified elements but not the exclusion of any other elements.

[0024] With reference to the Fig. 1 to 5, a motor-driven door lock for a vehicle according to an exemplary embodiment of the present invention can comprise a latch part 10 which is caught on or released from a locking bar attached to the vehicle, so that the door can be opened from the vehicle body, a door locking and release part 20 which applies a torque to the latch part 10 to allow the latch part 10 to be locked on or released from the locking bar, and a release part 30 which applies a torque to the latch part 10 to cause the vehicle door to spring forward from the vehicle body after the door has been released from the vehicle body by the door locking and release part 20.

[0025] The latch part 10 can include a latch 11 (e.g., a locking latch) rotatably mounted on one side of a first base plate 1 and which has a locking groove 111 into which the locking bar, which is attached to the vehicle body, can be inserted or separated from it, a latch gear or, for example, an arc-shaped latch tooth rail (hereinafter referred to as: latch gear) 112, which is formed on one side of it, and a claw 12, which is attached to the first base plate 1 in order to be rotatable and to be in close contact with the latch 11 in order to limit the rotation of the latch 11, or to be separated from the latch 11 in order to allow the latch 11 to rotate freely.

[0026] The door locking and release part 20 can include a main motor 21, which is mounted on a second base plate 2 and is rotatable in the clockwise and counterclockwise direction, and which has a first drive gear 211 (e.g., a worm gear), a first driven gear 22 (e.g., a two-stage spur gear) which engages with the first drive gear 211, and a claw release lever 23, which is coupled to the claw 12 with the first, intermediately arranged base plate 1 in order to be rotatable as a single unit (see the Fig. 4), and have an actuating lever 24 which engages with the first driven gear 22 and rotates while receiving a torque from the first driven gear 22 to rotate the claw release lever 23.

[0027] The protruding part 30 can have an auxiliary motor 31, which is attached to the first base plate 1 and is provided with a second drive gear 311 (e.g. a worm gear), a second driven gear 32, which engages with the second drive gear 311 (e.g. forming a worm gear with it), and a third driven gear 35 (e.g. a worm gear), which engages with the second driven gear 32 and simultaneously engages with the ratchet gear 112.

[0028] When the user operates a release lever or button attached to the door, a door locking control device can detect this to provide an actuation signal for the main motor 21 to operate the main motor 21.

[0029] With reference to the Fig. 6. The first drive gear 211 and the first driven gear 22 rotate through the drive of the main motor 21. The actuating lever 24, which engages with the first driven gear 22 (e.g., by means of a gear segment), is rotated to rotate the claw release lever 23. The claw 12 rotates together through the rotation of the claw release lever 23 and is set apart from the latch 11, so that the latch 11 can rotate freely, which allows the door, which is locked to the vehicle body, to be released.

[0030] The claw release lever 23 can be provided with two seat projections 231, and the actuating lever 24 can be provided with a pressure projection 241 which sits on the seat projections 231 to push and turn the claw release lever 23.

[0031] Furthermore, the door locking control device can provide an actuation signal for the auxiliary motor 31 to operate it.

[0032] Then, as it says in the Fig. As shown in Figure 7, the second drive gear 311, the second driven gear 32 and the third driven gear 35 rotate successively, the torque of the third driven gear 35 is transmitted to the pawl gear 112, so that the pawl 11 is forced to rotate, which causes the vehicle door, which is released from the vehicle body, to spring out from the vehicle body.

[0033] Therefore, since a passenger / occupant can hold the pop-out door of the vehicle with their hand and easily open the door, there is no need to attach a conventional, external handle and associated parts to the vehicle door, making it possible to reduce the number of parts, weight and cost, and to improve the appearance and marketability of the vehicle.

[0034] Although this invention has been described in connection with what are currently considered practical, exemplary embodiments, it is to be understood that the invention is not limited to the disclosed embodiments. On the contrary, it is intended to cover numerous modifications and equivalent arrangements, which are included in the scope of the appended claims.
