Description

Technical Field

[0001] The present application relates to a side door for a motor vehicle and a motor vehicle having the side door. Background Art

[0002] In modern motor vehicles, the conventional side door handles that mechanically unlock the side door lock by the user operating the side door are sometimes no longer installed on the side doors, but side doors that unlock the side door lock electromechanically are installed. For example, a side door handle in the form of a winglet is constructed on such a side door, which only serves as a gripping aid for grasping or holding and pulling open the unlocked side door.

[0003] This design is disadvantageous when there is no electrical energy supply to the side door, i.e. in the so-called blackout state. In this state, an emergency unlocking system is required, which enables the side door lock to be unlocked autonomously from the rest of the onboard electrical system of the motor vehicle and thus the motor vehicle side door to be opened.

[0004] This can be achieved, for example, in a motor vehicle by means of an external energy source or a mechanical solution with a Bowden cable connected to a side door lock in the front wheel arch of the motor vehicle and a user interface.

[0005] WO 2020239795A1 relates to an unlocking system for unlocking a door of a motor vehicle having a locking system. The unlocking system comprises an energy storage device and an energy receiving device, wherein the energy storage device is configured to provide unlocking energy to the locking system, by means of which the locking system can switch from a locked state to an unlocked state, and the energy receiving device is connected to the energy storage device and configured to wirelessly receive electrical energy from an energy source separated from the motor vehicle and provide the electrical energy to the energy storage device. Summary of the invention

[0006] Based on the prior art, the task of the present application is to propose a device suitable for enriching the prior art.

[0007] The specific design of the present application can solve the task of optimizing the positioning of the emergency unlocking system of the motor vehicle side door and in particular the positioning of the user interface of the emergency unlocking system.

[0008] This object is achieved by the features of the independent claim. The dependent claims contain optional developments of the application.

[0009] The object is therefore achieved by a side door for a motor vehicle, comprising a side door handle, a locking mechanism for locking the side door and an emergency opening system connected to an opening mechanism, by means of which the opening mechanism can be manually actuated. A user interface for actuating the emergency opening system is integrated into the side door handle.

[0010] In other words, a side door, in particular an electric side door, is provided, whose locking mechanism or locking system no longer has to be or is no longer mechanically actuated by a user in normal operation of the motor vehicle in order to open the side door as is conventional.

[0011] Such a side door may be referred to as an electrical side door. The side door is equipped with an emergency opening system or emergency unlocking system, which a user can use to unlock the locking system and thus open the side door in a state where the motor vehicle cannot provide or does not provide any electrical energy to unlock the locking system.

[0012] By operating the emergency opening system, the locking mechanism of the side door is unlocked, so that the side door can be opened. For this reason, the emergency opening system comprises a user interface, and the user can especially mechanically operate this interface and thereby unlock the locking mechanism.

[0013] In contrast to conventional solutions which propose to arrange the interface in the wheel arch or the B-pillar and thus outside the side door handle, the present application proposes to integrate the user interface in the side door handle itself in a cost-effective and ergonomic manner.

[0014] The optional expansion scheme of the above-mentioned side door is elaborated in detail below.

[0015] The user interface may comprise a flap which is integrated in the side door handle at a position accessible from the outside. The emergency opening system may be operated by operating the flap and the locking mechanism may thus be unlocked by the operated emergency opening system.

[0016] The flap can be integrated into the side door handle in such a way that the emergency opening system can be actuated by moving the flap.

[0017] The flap can be integrated into the side door handle in such a way that the emergency opening system can be actuated by rotating the flap.

[0018] The locking mechanism may comprise a side door lock which can be unlocked mechanically and / or electrically by actuating an emergency opening system, in particular a flap.

[0019] The flap can have a sensor which is designed to output a control signal for unlocking the side door lock to the locking mechanism when the flap is actuated. The energy supply of the sensor can be carried out by an external energy source.

[0020] The flap can have a bowden cable, which is designed to unlock the side door lock when the flap is actuated. This can be achieved in that the emergency unlocking is directly triggered by actuating, in particular pulling open, the flap. Specifically, this means that the bowden cable is connected to the flap. However, the application is not limited thereto. More precisely, it is also conceivable that a pull ring connected to an emergency opening system, for example via a bowden cable, is exposed by actuating, in particular flipping open the flap, which pull ring can be pulled in a subsequent step to unlock the emergency opening system.

[0021] The side door handle can be implemented in the form of a winglet. A winglet can be understood as a component conventionally used in the aviation industry, which protrudes outwardly from the motor vehicle side door in an upward or downward curved manner and thus forms a laterally outwardly offset handle groove, into which the user can reach and thus grasp the side door when opening or pulling it apart.

[0022] The winglet can therefore have a substantially horizontally extending section and a substantially vertically extending section, the vertically extending section being spaced apart from the outer skin of the side door by the horizontally extending section.

[0023] Thus, a gap, referred to above as a handle groove, is formed between the vertically extending section and the door skin, which is open to the front and rear and through which air can flow along the skin of the motor vehicle during travel of the motor vehicle. The winglet is therefore an aerodynamically advantageous design of a side door handle.

[0024] The side door handle can be arranged at the height of a window waist region of a side window of the side door and on a B-pillar of the side door.

[0025] The above content can be summarized in other words and with reference to a more specific embodiment of the present application described below, but this is not a limitation of the present application: the emergency opening mechanism (which, for example, includes a Bowden cable connection) can be directly integrated into the winglet. This can be realized in the form of a flap, which is connected to the lower side of the winglet, for example. In particular, it is also conceivable that the flap is integrated on the upper side of the winglet, for example, rotationally or by a sliding mechanism. The flap can also be integrated slidingly or rotationally to the front of the vehicle. In addition, it is also conceivable that a panel is integrated on the outermost surface of the winglet in the width direction of the motor vehicle. The panel can then be removed and the Bowden cable connected to the flap can be pulled accordingly to operate the emergency opening mechanism in this way. By pulling the cover or flap, the side door lock can be urgently unlocked mechanically or electronically. The triggering can be carried out by means of a signal (for example, by integrating a sensor in the cover) or purely mechanically (for example, by means of a Bowden cable).

[0026] Furthermore, the present application relates to a motor vehicle having the above-mentioned side door.

[0027] The motor vehicle may be a passenger vehicle, such as a car, and / or a commercial vehicle, such as a truck.

[0028] The above statements regarding the side doors also apply analogously to the motor vehicle and vice versa. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Refer to the following Figure 1 An implementation method is described. The accompanying drawings are as follows:

[0030] Figure 1A motor vehicle having a side door according to the present application is schematically shown in a perspective exterior view, the viewing direction being in the longitudinal direction of the motor vehicle. DETAILED DESCRIPTION

[0031] exist Figure 1 , which has an X-axis representing the longitudinal direction X of the vehicle, extending from the rear to the front of the vehicle 1, a Y-axis representing the width direction Y of the vehicle, and a Z-axis representing the height direction Z of the vehicle. All axes X, Y and Z are respectively at right angles to each other. The longitudinal direction X and the width direction Y of the vehicle form a substantially horizontal plane, and the height direction Z of the vehicle, which extends substantially parallel to the vertical line, is perpendicular to the plane.

[0032] exist Figure 1 The motor vehicle 1 , which is partially shown from the outside in a perspective view, has a side door 2 with an outer skin 3 , a B-pillar 4 , a window waist region 6 for a side window or window glass 7 , and a side door handle designed as a winglet 5 , which is arranged at the level of the window waist region 6 and on the B-pillar 4 .

[0033] The side door 2 further comprises a locking mechanism for locking the side door 2 and an emergency opening system connected to the locking mechanism, by means of which the locking mechanism can be manually operated or unlocked.

[0034] The locking mechanism itself is arranged in the side door 2 and is therefore not Figure 1 In addition to the user interface of the emergency opening system and the Bowden cable 10 which is only schematically shown, the emergency opening system is also not shown. Figure 1 The external view is shown in FIG.

[0035] More precisely, the emergency opening system has a user interface designed as a flap 8 which is integrated into the winglet 5 at a location accessible to the user from the outside (here from the rear) and which is mechanically connected to the door lock of the locking mechanism via a Bowden cable 10 .

[0036] As in Figure 1 9 is shown only for explanation purposes and indicated by the arrow on the flap 8 , the user can rotate the flap 8 upwards and then pull it for emergency unlocking of the side door 2 , in order to thus unlock the door lock of the locking mechanism and thus the side door 2 via the Bowden cable 10 .

[0037] The application is not limited to a rotational movement of the flap 8 , and other solutions are also conceivable, in which the flap 8 can also slide along the winglet 5 , for example in addition to or instead of the rotation.

[0038] Furthermore, the present application is not limited to purely mechanical solutions, but in particular a mechatronic solution can be provided, in which, for example, a sensor mounted on the flap 8 detects the user's operation of the flap 8 and then electrically unlocks the side door lock via a control signal.
