Description

Technical Field

[0001] The present invention relates to a door handle system for a motor vehicle, comprising a support element, an operating element movably mounted on the support element, a locking device, and a closing device for opening a door or cover of the motor vehicle, the closing device being effectively connected to the operating element, wherein the operating element is movable from a rest position to an open position by a second actuation movement manually performed by a user to open the door or cover.

[0002] The present invention further relates to a method for unlocking and opening a door or cover of a motor vehicle, wherein an operating element disposed in its rest position is moved by a user through an actuation path to an open position for opening the door or cover. Background Technology

[0003] Such door handle systems for motor vehicles and methods for unlocking and opening doors or covers of motor vehicles are known from the prior art. These systems have an operating element formed as a door handle, which is grasped by a user, allowing the door or cover of the motor vehicle to be opened. In this case, the actuation of the operating element acts on a closing device to enable the opening of the door or cover. However, before opening, the closing device must first be unlocked, for which a locking device is used, which checks the user's legitimacy upon unlocking. For example, the locking device could be a mechanical lock cylinder, into which the user must insert a mechanical key and turn it to unlock. The user must then operate the operating element, designed as a door handle in the known door handle system, to open the door or cover. Therefore, for the user, two operational steps on two different devices in the known door handle system are necessary for unlocking and opening, which is time-consuming and inconvenient for efficient handling, for example, when entering a motor vehicle. Summary of the Invention

[0004] The purpose of this invention is to provide a solution in which a door handle system and method for unlocking and opening doors or covers of motor vehicles provides users with simplified and efficient operation.

[0005] According to the present invention, this objective is achieved by a door handle system of a motor vehicle having the features described herein.

[0006] The door handle system for motor vehicles of the present invention includes a support element, an operating element movably mounted on the support element, a locking device formed by a first effective connection to the operating element, and a closing device for opening a door or cover of the motor vehicle formed by a second effective connection to the operating element. The operating element can be moved from a rest position to an unlocked position by a first actuation manually performed by the user to unlock the closing device, and the operating element can be moved from a rest position to an open position by a second actuation manually performed by the user to open the door or cover.

[0007] Similarly, according to the present invention, this objective is achieved by unlocking and opening a door or cover of a motor vehicle having the features described herein.

[0008] In the method according to the invention, an operating element positioned at its rest position is moved by a user through a first actuation path to an unlocked position for unlocking the closing device, and the operating element is then moved back to its rest position. The operating element, now back at its rest position, is then moved by the user through a second actuation path to an open position for acting as a closing device to open a door or cover.

[0009] The advantageous and useful designs and further improvements of the invention are derived from the dependent rights.

[0010] This invention provides a door handle system for motor vehicles, characterized by its simple design and low cost. Furthermore, this invention provides a method for unlocking and opening doors or covers of motor vehicles, which, compared to existing technologies, features simple steps performed on a single component. By using an operating element, the unlocking and opening steps can be performed simultaneously, eliminating the need for the user to modify the operating elements present in existing technologies when switching from unlocking via a mechanical key to opening via the door handle. Consequently, this invention not only makes unlocking and opening more convenient but also faster, increasing user convenience several times over.

[0011] The present invention provides that the first actuated movement is formed as a rotational movement of the operating element from a rest position. Therefore, it is clear to the user which manipulations of the operating element are necessary for the unlocking process. Furthermore, the type of execution is familiar to the user, although, compared to the prior art, the execution is now performed on the operating element rather than with the aid of a mechanical key.

[0012] In the design of this invention, the first effective connection comprises an actuating rod fixedly connected to the operating element, a transmission rod connected to the locking element of the locking device, and a coupling rod connected to the actuating rod and the transmission rod, providing a possibility for achieving a simple structure and small footprint for realizing the first effective connection. Through this system of levers and links, rotational movement can be performed in a very simple manner without requiring the user to apply significant force.

[0013] Regarding unlocking, the present invention provides a locking device having a housing element and a cylindrical core connected to a transmission rod, wherein the cylindrical core is disposed within the housing element and rotatably mounted relative to the housing element, and wherein the locking device further includes an actuator that, after authorized user authentication, forms an effective connection between the cylindrical core and a locking element movable to a locked or unlocked position. Therefore, the locking device is essentially formed according to the type of mechanical lock cylinder.

[0014] Unlike mechanical lock cylinders in the prior art, a further design of the present invention provides that the locking bolt is movably mounted on the housing element, and after authorized user authentication, the actuator moves the locking bolt from a locked position where the locking bolt blocks and / or interrupts the effective connection to a released position where the cylindrical core and the locking element are effectively connected, and the user's manual handling of the operating element moves the locking element to the unlocked position.

[0015] The present invention further provides a compact and space-saving design, wherein the locking bolt is movably mounted on the cylindrical core and engages with the housing element in the locked position to prevent movement of the cylindrical core relative to the housing element.

[0016] To prevent the obstruction from being overcome by applying excessive force in the event of an unauthorized user, a further design of the invention provides that the cylindrical core and the drive rod are connected together by a safety coupling, which securely connects the cylindrical core and the drive rod in the released position of the locking bolt, and, through the safety coupling in the locked position of the locking bolt, the drive rod rotates relative to the cylindrical core when a predetermined actuating force is exceeded.

[0017] Furthermore, to ensure that the user clearly understands the handling of the operating element necessary for the opening step, the present invention provides a second actuation movement formed as a translational movement of the operating element from a rest position. This ensures a clear separation between the movements required for unlocking and opening.

[0018] In this respect, it is advantageous in the design of the present invention if the translational movement is an action on the pull wire movement of the Bowden line connected to the closing device.

[0019] To achieve different movements, in the design of the present invention, if the operating element has a user-accessible gripping portion and a coupling pin that mates with the gripping portion, the coupling pin is located in the rest position of the operating element and is rotatably mounted in a receiving sleeve on a support element, wherein the receiving sleeve is fixedly connected to the actuating rod, in the first actuation movement, the coupling pin and the receiving sleeve are movably coupled, and in the second actuation movement, the coupling pin and the receiving sleeve are movably decoupled and arranged to move out of the receiving sleeve.

[0020] In the design of the method of the present invention, the different movement processes are clearly separated for the user, and the operating element is rotated by the user as it moves along the first actuation path.

[0021] Similarly, it is advantageous for the design method of the present invention that the operating element is movably mounted in the receiving space of the support element if the user pulls the operating element out of the receiving space of the support element while it moves along the second actuation path.

[0022] The method is further designed to authenticate or check the user's authorization before unlocking or closing the device. This authentication can be performed, for example, by transmitting access authorization data from a mobile phone to a vehicle-side control unit.

[0023] Finally, the method of the present invention is provided to open the cover element that shields the operating element before unlocking the closing device.

[0024] It should be understood that, without departing from the framework of this invention, the features explained above and below can be used not only in their respective specified combinations, but also in other combinations, or individually. The framework of this invention is defined only by the claims. Attached Figure Description

[0045] exist Figure 1 The vehicle 1 is shown in the form of a passenger car. In this example, the vehicle has multiple doors 2 and covers 3. The doors 2 and covers 3 can be locked by means of the door handle system 4 of the present invention, and can be unlocked and opened by means of the operating element 5, wherein... Figure 1 The door handle system 4 is shown exemplarily only for the driver's door 2. When the cover element 6 is in the closed position, the operating element 5 is covered by the cover element 6. Unlocking and opening the door 2 or cover 3 requires the cover element 6 to be in an open position, in which the cover element 6 releases access to the operating element 5, thus allowing it to be actuated by the user 7.

[0046] Door handle system 4 Figure 2 The vehicle is shown in a perspective overall view, and in addition to the operating element 5, it also has a support element 8 mounted on the door 2 or cover 3 of the motor vehicle 1, a locking device 9 formed with the operating element 5 via a first effective connection 10, and a closing device 11 for opening the door 2 or cover 3 of the motor vehicle 1 formed with the operating element 5 via a second effective connection 12. The operating element 5 is movably mounted on the support element 8.

[0047] Figures 3 to 7 The process for unlocking and opening the door 2 or cover 3 of the motor vehicle 1 is shown. Figure 3 The arrangement of the cover element 6 in the closed position and covering the operating element 5 in its rest position is shown.

[0048] Before User 7 begins the unlocking and unlocking process, User 7 keeps their smartphone 14 as follows: Figure 3 The receiving device 16 is shown mounted on component 15 of motor vehicle 1. For example, component 15 may be the B-pillar of motor vehicle 1. Data for authentication is stored on smartphone 14 and transmitted to the vehicle-side receiving device 16. Then, before unlocking the unlocking device 9, the authorization of user 7 is authenticated or checked, where successful authentication causes the blocking of the locking device 9 to be released, and user 7 can act on the locking device 9 to unlock the closing device 11 by means of the locking device 9.

[0049] After successful authentication, and before the closing device 11 is unlocked, the user 7 opens the cover element 6 of the shielding operation element 5, as follows: Figure 4As shown. The cover element 6 is opened by pressure actuation, thereby actuating the push-push mechanism, causing the spring-preloaded cover element 6 to subsequently swing autonomously in its open position. Figure 5 In this configuration, the cover element 6 is arranged to swing open and occupy its open position, wherein the cover element 6 allows access to the receiving space 17 formed in the support element 8, wherein the operating element 5 is arranged in its rest position.

[0050] User 7 can now access and manipulate element 5, and can grasp it, such as Figure 6 As shown. To unlock the closing device 11, the operating element 5, positioned in its rest position, is moved by the user 7 via a first actuation path 18 to the unlock position of the locking device 9. During this movement along the first actuation path 18, the operating element 5 is rotated by the user 7, resulting in a rotational movement for unlocking the closing device 11. Starting from its rest position, the operating element 5 rotates approximately 40° until it reaches the unlock position. Therefore, the first actuation movement 18 is configured as a rotational movement of the operating element 5 from its rest position to unlock the closing device 11. The operating element 5 then moves back to its rest position.

[0051] Finally, Figure 7 The diagram shows the arrangement of the operating element 5 in its open position. Here, the operating element 5, which moves back to its rest position, is moved to the open position by the user 7 via the second actuation path 19 so as to interact with the closing device 11 for opening the door 2 or cover 3. During movement along the second actuation path 19, the operating element 5 is pulled out by the user 7 from the receiving space 17 of the support element 8, where the operating element 5 is movably mounted. Therefore, unlike the first actuation movement, the second actuation movement 19 is configured as a translational movement of the operating element 5 from its rest position.

[0052] Following the above description of the method of the present invention for unlocking and opening the door 2 or cover 3 of a motor vehicle 1, the structural design of the door handle system 4 of the present invention is described below.

[0053] As shown in the method description, the operating element 5 can be moved from a rest position to an unlocked position for unlocking the closing device 11 by a first actuation movement 18 manually performed by the user 7. Furthermore, the operating element 5 can be movably moved from a rest position to an open position for opening the door 2 or cover 3 by a second actuation movement 19 manually performed by the user 7. Therefore, two operations, namely unlocking and opening, can be performed by means of the operating element 5; previously, two elements or components were always required in the prior art.

[0054] As described above, the closing device 11 is unlocked by means of the first actuation movement 18 applied by the user 7, wherein the operating element 5 is moved from its rest position (see above) Figure 8 Move to its unlocked position (see Figure 12 ), thereby removing the locking element 20 of the locking device 9 from the locked position (see Figure 8 Move to the unlock position (see) Figure 12 and 13 The locking element 20 connected to the locking device 11 is part of the locking device 9, which is formed as a lock cylinder, such as... Figure 8 As shown. The operating element 5 is connected to the locking device 9 via the first effective connection 10.

[0055] like Figures 8 to 13 As shown, the first effective connection 10 has an actuating rod 21, a transmission rod 22, and a coupling rod 23. The actuating rod 21 is fixedly connected to the operating element 5. Furthermore, the transmission rod 22 is connected to the locking element 20 of the locking device 9. Finally, the coupling rod 23 connects the actuating rod 21 to the transmission rod 22. A receiving sleeve 24 is rotatably mounted on the support element 8. The receiving sleeve 24 is fixedly rotatably connected to the actuating rod 21, such that rotation of the receiving sleeve 24 simultaneously deflects the actuating rod 21. Specifically, from... Figure 10 and 11 As can be seen, the operating element 5 has a gripping portion 25 that can be grasped by the user 7 and a coupling pin 26 protruding from the gripping portion 25. In the rest position of the operating element 5, the coupling pin 26 is at least partially disposed within the receiving sleeve 24, wherein the cross-section of the coupling pin 26 is formed as a quadrilateral, and correspondingly, the free cross-section of the receiving sleeve 24 is also formed as a quadrilateral. In the first actuation movement 18, since the operating element 5 rotates purely from the rest position to the unlocked position, the coupling pin 26 and the receiving sleeve 24 are movably coupled in the first actuation movement 18, causing the receiving sleeve 24 with the coupling pin 26 of the operating element 5 to rotate—when the operating element 5 performs the first actuation movement 18, the operating element 5, the receiving sleeve 24, and therefore the actuating rod 21 rotate together. The receiving sleeve 24 has an end-side coupling web 27 that engages with a coupling groove 28 formed on the actuating rod 21, through which the receiving sleeve 24 and the actuating rod 21 are rotatably connected together (e.g., see...). Figure 10 The first actuation movement 18 causes the actuation rod 21 to tilt, which in turn causes the transmission rod 22 to tilt. The transmission rod 22 then moves the locking element 20 from the locked position to the unlocked position through the locking device 9.

[0056] However, the prerequisite for the aforementioned locking element 20 to move from the locked position to the unlocked position is that the locking device 9 is also released for this purpose. As mentioned above, the locking device 9 is formed according to the type of lock cylinder, and the locking device 9 of the present invention is an electronic lock cylinder. Figures 14 to 17 The locking device 9, shown in more detail, has a housing element 29, a cylindrical core 30, and a locking element 20, wherein the cylindrical core 30 is connected to the drive rod 22. The cylindrical core 30 is disposed within the housing element 29 and is rotatably mounted relative to the housing element 29. The housing element consists of two housings that can be screwed together. The locking device 9 also has an actuator 31 (see [link to manual]). Figure 17 After authorized user 7 authentication, an effective connection is formed between the cylindrical core 30 and the locking element 20, which can be moved to a locked or unlocked position. In the sense of this invention, the establishment of an effective connection is the release of a blockage in the movement of the movable part, and the effective connection typically constitutes a chain of mechanical action. In the illustrated embodiment, a motor-driven locking bolt 32 is movably mounted, wherein the locking bolt 32 is movable along the longitudinal direction of the cylindrical core 30. Here, the locking bolt 32 is effectively connected to the actuator 31, such that after authorized user 7 authentication, the actuator 31 moves the locking bolt 32. In this embodiment, this is a linear movement of the locking bolt 32, wherein the movement occurs in the longitudinal direction of the cylindrical core 30. After authorized user authentication, the actuator 31 moves the locking bolt 32 from the locked position (see, for example, [link to example]). Figure 14 Move to the release position (see, for example) Figure 15 In the locked position, the locking bolt 32 interrupts the effective connection, which is the locking of the rotational movement of the cylindrical core 30. On the other hand, in the released position, the locking bolt 32 is arranged such that it no longer obstructs the effective connection, allowing the cylindrical core 30 to be manually manipulated by the first actuation movement 18 of the user operating element 5 to move the locking element 20 from the locked position to the unlocked position. Thus, successful authentication causes the actuator 31 to operate, thereby moving the locking bolt 32 from the locked position to the released position, thereby establishing an effective connection with the locking element 20, allowing the user to now manually move the locking element 20 from the locked position to the unlocked position by means of the operating element 5, thus placing the locking device 9 in the unlocked state. The locking bolt 32 is movably mounted on the cylindrical core 30 such that in the locked position, the locking bolt 32 engages with the housing element 29 and prevents movement of the cylindrical core 30 relative to the housing element 29. For this purpose, in the locked position, a portion of the locking bolt 30 is disposed in a locking opening 33 formed in the housing element 29 (see, for example, [link to relevant documentation]). Figure 14And it engages with it in such a way that rotational movement of the cylindrical core 30 relative to the housing element 29 is prevented. Rotation of the cylindrical core 30 relative to the housing element 29 is possible when a portion of the locking bolt 32 is removed from the locking opening 33 by means of the actuator 31 and the locking bolt 32 is in its released position, wherein the cylindrical core 22 is fixedly connected to the locking element 20 formed as a cylindrical shaft. Figure 14 In the middle, the locking bolt 32 is set in its locked position, while Figure 16 and 17 In the middle, the locking bolt 32 is positioned in its released position. Figure 17 In the middle, the cylindrical core 30 is further arranged in a twisted manner relative to the housing element 29 for unlocking the locking device 9, which can also be achieved from the position relative to the housing element 29 for unlocking the locking device 9. Figure 16 This can be seen in the position of the transmission rod 22.

[0057] Figure 15 One embodiment is illustrated, in which the cylindrical core 30 and the drive rod 22 are connected together by a safety coupling 34. This safety coupling 34 securely connects the cylindrical core 30 and the drive rod 22 in the released position of the locking bolt 32, and through this safety coupling 34, in the locked position of the locking bolt 32, the drive rod 22 is rotatable relative to the cylindrical core 22 when a predetermined actuating force is exceeded. The safety coupling 34 ensures that, for unlocking, the locking bolt 32 is also actually positioned in its released position, and that the locking bolt 32 is not forcibly released from the locking opening 33. The safety coupling 34 has compression springs 34, each with a ball 35 at its respective end. The compression springs 34 are accommodated in openings formed laterally within the drive rod 22, with the balls 35 protruding segmentally from the openings and along the circumferential edge of the portion of the drive rod 22 directly connected to the cylindrical core 30. Each protruding spherical portion is positioned in a corresponding opening in the coupling portion of the cylindrical core 30, such that under actuation force, the sphere 35 engages with the cylindrical core 30, causing the cylindrical core 30 to rotate when the locking bolt 32 is in its released position, due to the rotation of the transmission rod 22. Conversely, if the locking bolt 32 is not in the released position and the force used to rotate the transmission rod 22 exceeds the specified actuation force, the sphere 35 emerges from the opening of the cylindrical core 30 and is pressed into the opening of the transmission rod 22 under the force of the compression spring 34, causing the transmission rod 22 to rotate relative to the fixed cylindrical core 30.

[0058] Figure 18 and 19The diagram shows a view of the operating element 5 in the open position after it has been previously moved from its rest position, corresponding to a second actuation movement 19 caused by the user 7. In this second actuation movement 19, action is performed via the second active connection 12 on the closing device 11 for opening the door 2 or cover 3. The second actuation movement 19 is a translational movement. More specifically, it is a pull-wire movement acting on the Bowden wire 36 connected to the closing device 11. The Bowden wire 36 is fixed to the coupling pin 26 of the operating element 5, wherein the coupling pin 26 is positioned in the open position of the operating element 5, moving out of the receiving sleeve 24, as... Figure 19 As shown. Accordingly, in the second actuation movement 19, the coupling pin 26 is decoupled from the receiving sleeve 24 and moved out of the receiving sleeve 24.

[0059] Of course, the invention described herein is not limited to the embodiments described and illustrated. Many modifications that are obvious to those skilled in the art corresponding to the intended application can be made to the embodiments shown in the figures without departing from the scope of the invention. The invention includes everything contained in the specification and / or shown in the drawings, including content that is obvious to those skilled in the art different from the specific embodiments.
