Description

Technical Field

[0001] This disclosure relates to a door tilting system for a sliding vehicle door. The door tilting system is formed as part of a pivot joint between the door and a movable arm structure that connects the door to the vehicle body structure. This disclosure also relates to a vehicle including at least one door tilting system and a method for adjusting the door tilting system for the sliding door. Background Technology

[0002] There are different types of doors that allow access to the vehicle interior, and traditional door constructions include hinged doors that are pivotally connected to the body structure via hinges, and sliding doors that are slidably connected to the body structure via tracks and a movable arm structure. In traditional hinged doors, the geometry of the door connection is typically set by three connection points formed by two hinges and a door latch. In traditional sliding doors, the geometry of the door connection is also typically set by three connection points formed by tracks and a movable arm structure. These connection points can be adjusted to provide the correct door position relative to the body structure in the longitudinal, lateral, and perpendicular directions of the vehicle. Correct door position is crucial for a tight seal between the door and the body structure, preventing noise, dust, and other contaminants from entering the interior. Correct door position is also important for the aesthetically correct positioning of the door relative to the body structure. Door adjustment systems are often complex, and the door adjustment process is often a time-consuming step during vehicle assembly. Therefore, an improved method for adjusting doors relative to the body structure is needed to enable a fast and efficient vehicle assembly process. Summary of the Invention

[0003] The purpose of this disclosure is to provide a door tilting system for a sliding vehicle door that avoids the aforementioned problems, a vehicle including at least one door tilting system, and a method for adjusting the door tilting system for the sliding vehicle door. This objective is achieved at least in part by the features of the independent claims. The dependent claims contain further improvements to the door tilting system for a sliding vehicle door and the method for adjusting the door tilting system for the sliding vehicle door.

[0004] This disclosure relates to a door tilting system for a sliding vehicle door, wherein the door tilting system is formed as part of a pivot joint between the door and a movable arm structure connecting the door to a vehicle body structure. The door tilting system includes an inner sleeve and an outer sleeve, wherein the inner sleeve is disposed inside the outer sleeve and is rotatably arranged relative to the outer sleeve. The inner sleeve includes a receiving opening configured to receive a fastening device, wherein the receiving opening has an elongated configuration and extends in a first direction along a first axis passing through the inner sleeve. The door tilting system is configured to change the first direction of the receiving opening relative to the outer sleeve as the inner sleeve rotates and shifts relative to the outer sleeve.

[0005] The advantage of these features is that the door tilting system achieves a simple and efficient way to adjust the door by changing the first direction of the receiving opening relative to the outer sleeve when the inner sleeve rotates and shifts relative to the outer sleeve. Therefore, the inner sleeve rotates relative to the outer sleeve to achieve the correct door position, and through this rotational shift, the tilt angle of the fastening device is adjusted, which in turn affects the position of the door relative to the body structure to which it can be movably attached. The correct door position is crucial for the correct locking position of the door to the body structure and for achieving a sealed connection between the door and the body structure, thus preventing noise, dust, and other contaminants from entering the interior compartment. The simple adjustment through rotational shift between the inner and outer sleeves is also important for the aesthetically correct positioning of the door relative to the body structure. The simple door adjustment operation enables fast and efficient vehicle assembly. A sliding door is defined as any type of door connected to the body structure via one or more arm structures, wherein one or more arm structures pivot relative to the door via pivot joints, thereby allowing longitudinal displacement of the door relative to the body structure, or a combination of longitudinal and lateral displacement.

[0006] According to one embodiment, the inner sleeve includes an outer surface, and the outer sleeve includes an inner surface. The outer surface of the inner sleeve is arranged relative to the inner surface of the outer sleeve, wherein the outer surface of the inner sleeve is configured to move relative to the inner surface of the outer sleeve during rotational displacement of the inner sleeve relative to the outer sleeve. This configuration enables an efficient and compact door tilting system, wherein the inner sleeve is arranged inside the outer sleeve and rotatably relative to the outer sleeve for simple tilt adjustment operations.

[0007] According to one embodiment, the inner surface of the outer sleeve is configured to receive an inner opening of the inner sleeve. The inner opening forms a channel-like structure within the outer sleeve and is configured to receive the inner sleeve. The outer surface of the inner sleeve is arranged relative to the inner surface of the outer sleeve, and the inner sleeve rotates within the inner opening of the outer sleeve during rotational displacement relative to the outer sleeve. The inner opening suitably has a circular cross-sectional shape, allowing rotational movement of the inner sleeve relative to the outer sleeve.

[0008] According to one embodiment, the inner opening extends through the outer sleeve. In this way, the inner opening forms a channel-like or tubular structure within the outer sleeve for receiving the inner sleeve. The inner opening suitably has a circular cross-sectional shape to allow rotational movement of the inner sleeve relative to the outer sleeve.

[0009] According to one embodiment, the outer surface of the inner sleeve is arranged as a cylindrical surface, and the inner surface of the outer sleeve is arranged as a cylindrical surface. The cylindrical surface allows for efficient rotational displacement of the inner sleeve relative to the outer sleeve.

[0010] According to one embodiment, the outer surface of the inner sleeve extends in a second direction, which is different from the first direction. The extension in the second direction enables tilt adjustment operations.

[0011] According to one embodiment, the outer sleeve is connected to the outer end of the movable arm structure. The outer sleeve can be attached to the arm structure or form an integral structural part of the arm structure. For example, the outer sleeve can be welded to the outer end of the arm structure for a secure and reliable connection, or attached to the outer end of the arm structure by other suitable attachment devices.

[0012] According to one embodiment, the door tilting system further includes a first bracket and a second bracket attached to the door. An outer sleeve and an inner sleeve are arranged between the first bracket and the second bracket. In this way, each of the outer sleeve and the inner sleeve extends between the first bracket and the second bracket. This design enables a compact structure for the door tilting system, wherein the brackets and sleeves determine the tilt position of the door.

[0013] According to one embodiment, the first bracket includes a first fastening opening, and the second bracket includes a second fastening opening. In the assembled state of the door tilting system, a fastening device extends through the first fastening opening, the receiving opening, and the second fastening opening. This configuration enables a secure connection between the components involved, and the second fastening opening may, for example, be threaded to engage threads arranged on the fastening device to achieve a reliable connection between the door and arm structure via the bracket and sleeve.

[0014] According to one embodiment, a slot is arranged in the sidewall structure of the outer sleeve. The inner sleeve includes a locking member extending from the inner sleeve through the slot to the outer side of the outer sleeve. The locking member is configured to releasably attach the inner sleeve to the outer sleeve. The slot may have an elongated configuration and extend through the sidewall structure of the outer sleeve, forming an opening that allows access to the inner sleeve from the outer surface of the outer sleeve. The locking member is allowed to move along the slot as the inner sleeve rotates relative to the outer sleeve.

[0015] According to one embodiment, the locking member in the unlocked state unlocks the inner sleeve from the outer sleeve, thereby allowing the inner sleeve to rotate relative to the outer sleeve. The locking member in the locked state locks the inner sleeve to the outer sleeve through frictional engagement between at least the locking member and the outer sleeve, thereby preventing rotational displacement of the inner sleeve relative to the outer sleeve. In the unlocked state, the locking member is allowed to move along a slot during rotational displacement of the inner sleeve relative to the outer sleeve, and when the inner sleeve reaches the desired position, the locking member is positioned in the locked state to prevent rotational displacement of the inner sleeve relative to the outer sleeve. The locking member can extend from the inner sleeve through the slot to the outside of the outer sleeve. In this way, locking and unlocking operations can be efficiently performed from the outside of the outer sleeve.

[0016] According to one embodiment, the inner sleeve includes a threaded opening, and a locking member is arranged to engage with a screw in the threaded opening. In the locked state, the locking member contacts the outer sleeve. With this configuration, the locking member is arranged as a screw extending from the inner sleeve through a slot to the outside of the outer sleeve. The locking member is screwed into the inner sleeve to enable both unlocking the inner sleeve from the outer sleeve and locking the inner sleeve to the outer sleeve.

[0017] This disclosure also relates to a vehicle that includes at least one door tilting system for a sliding door as described above.

[0018] This disclosure also relates to a method for adjusting a door tilting system for a sliding vehicle door, wherein the door tilting system is formed as part of a pivot joint between the door and a movable arm structure connecting the door to a vehicle body structure. The door tilting system includes an inner sleeve and an outer sleeve, wherein the inner sleeve is disposed inside the outer sleeve and is rotatably disposed relative to the outer sleeve. The inner sleeve includes a receiving opening configured to receive a fastening device, wherein the receiving opening has an elongated configuration and extends in a first direction along a first axis passing through the inner sleeve. The method includes the step of: rotating the inner sleeve relative to the outer sleeve, wherein the rotational displacement of the inner sleeve relative to the outer sleeve changes the first direction of the receiving opening relative to the outer sleeve.

[0019] The advantage of these features is that the method for adjusting the door tilt system provides an efficient way to adjust the door by changing the first orientation of the receiving opening relative to the outer sleeve through a simple operational step: the inner sleeve can rotate relative to the outer sleeve to reach the correct door position, and the tilt angle of the fastening device is adjusted by the rotational displacement, which in turn affects the position of the door relative to the vehicle body structure to which it is movably attached. The correct door position is crucial for the correct locking position of the door to the vehicle body structure and for achieving a sealed connection between the door and the vehicle body structure, thus preventing noise, dust, and other contaminants from entering the interior compartment. The simple adjustment through the rotational displacement between the inner and outer sleeves is essential for the aesthetically correct positioning of the door relative to the vehicle body structure. The simple door adjustment operation also enables rapid and efficient vehicle assembly.

[0020] According to one embodiment, a slot is arranged in the sidewall structure of the outer sleeve. The inner sleeve includes a locking member extending from the inner sleeve through the slot to the outside of the outer sleeve. The locking member is configured to releasably attach the inner sleeve to the outer sleeve. The method further includes the steps of: unlocking the inner sleeve from the outer sleeve to an unlocked state via the locking member to allow rotational displacement of the inner sleeve relative to the outer sleeve; displacing the inner sleeve relative to the outer sleeve to a desired position; and locking the inner sleeve to the outer sleeve to a locked state via the locking member to prevent rotational displacement of the inner sleeve relative to the outer sleeve. The slot may have an elongated configuration and extend through the sidewall structure of the outer sleeve, forming an opening that allows access to the inner sleeve from the outer surface of the outer sleeve. In the unlocked state, the locking member is allowed to move along the slot as the inner sleeve rotates relative to the outer sleeve, and when the inner sleeve reaches the desired position, the locking member is arranged in a locked state to prevent rotational displacement of the inner sleeve relative to the outer sleeve. The locking member may be arranged as a screw extending from the inner sleeve through the slot to the outside of the outer sleeve. The locking member is screwed properly into the inner sleeve to enable both unlocking and locking of the inner sleeve to the outer sleeve. This configuration allows for efficient locking and unlocking operations from the outside of the outer sleeve. Attached Figure Description

[0032] As mentioned above, such as from Figure 2 As understood in the text, door D is connected to the body structure B, and as... Figure 3 As shown, in the illustrated embodiment, two arm structures A are arranged at the lower part of the door D.

In the illustrated embodiment, each arm structure A is thus arranged to hold the door D relative to the vehicle body structure B and to displace it, and each arm structure A is thus suitably connected to the lower part of the vehicle body structure B. The door D may also have an upper arm structure for realizing a movable connection between the door D and the vehicle body structure B.

[0033] It should be understood that in other embodiments, one or more arm structures A can connect the door D to any suitable part of the body structure B. In other embodiments, the door D may be provided with any suitable number of arm structures A arranged at the lower and / or upper part of the door D, and one or more joints J between the arm structures A and the door D may be provided with a door tilting system S.

[0034] exist Figures 4a to 4c In the embodiments of the door tilting system S shown in 5a to 5d and 6a to 6d, the door tilting system S includes an inner sleeve 1 and an outer sleeve 2. Figure 5a and Figure 6a As indicated by the double arrows, the inner sleeve 1 is arranged inside the outer sleeve 2 and is rotatably arranged relative to the outer sleeve 2. The inner sleeve 1 includes a receiving opening 3, and the receiving opening 3 is configured to receive a fastening device 3a, such as a screw, bolt, locking pin, or other suitable fastening element, for connecting the arm structure A to the door D. The receiving opening 3 has an elongated configuration and extends in a first direction D1 along a first axis A1 passing through the inner sleeve 1. The receiving opening 3 thus extends through the inner sleeve 1, and in the illustrated embodiment, as from... Figures 5c to 5d As understood in 6c to 6d, the receiving opening 3 has a tubular or channel-like shape, the size of which is suitable for receiving the fastening device 3a, and there is not a large gap between the receiving opening 3 and the fastening device 3a.

[0035] like Figures 4a to 4c As shown in 5c to 5d and 6c to 6d, the door tilting system S also includes a first bracket 4 and a second bracket 5 attached to the door D. An outer sleeve 2 and an inner sleeve 1 are arranged between the first bracket 4 and the second bracket 5. In this way, as from... Figures 5c to 5d As understood in 6c to 6d, each of the outer sleeve 2 and the inner sleeve 1 extends between the first bracket 4 and the second bracket 5. The first bracket 4 includes a first fastening opening 4a, and the second bracket 5 includes a second fastening opening 5a, and in the assembled state SA of the door tilting system S, as Figures 4a to 4cAs shown in 5c to 5d and 6c to 6d, the fastening device 3a extends through the first fastening opening 4a, the receiving opening 3, and the second fastening opening 5a. When the door D is opened and closed, the arm structure A rotates about the fastening device 3a relative to the door D. In the illustrated embodiment, the second fastening opening 5a may, for example, be threaded to engage the threads arranged on the fastening device 3a, thereby achieving a secure connection between the door D and the arm structure A via a bracket and sleeve. The outer sleeve 2 is connected to the outer end A of the movable arm structure A. OE Furthermore, the outer sleeve 2 forms an integral structural part of the arm structure A. The outer sleeve 2 may, for example, be welded to the outer end A of the arm structure A. OE To achieve a secure and reliable connection, or to attach to the outer end A of the arm structure via other suitable attachment devices. OE .

[0036] The inner sleeve 1 is arranged as a separate structural member inside the outer sleeve 2, and the inner sleeve 1 is rotatably arranged relative to the outer sleeve 2. The inner sleeve 1 includes an outer surface 1a, and the outer sleeve 2 includes an inner surface 2a. The inner surface 2a of the outer sleeve 2 is formed in such a way as to receive an inner opening 2b of the inner sleeve 1. The inner opening 2b extends through the outer sleeve 2, and in such a way that the inner opening 2b forms a channel-like or tubular structure in the outer sleeve 2 configured to receive the inner sleeve 1. The inner opening 2b suitably has a circular cross-sectional shape to allow rotational movement of the inner sleeve 1 relative to the outer sleeve 2 about a second axis of rotation A2 extending in a second direction D2. In the illustrated embodiment, the inner opening has a circular cross-sectional shape and a constant diameter along its extension. However, depending on the design of the door tilting system, in other embodiments the inner opening may have any suitable shape that allows the inner sleeve to rotate relative to the outer sleeve, such as, for example, a conical or similar conical construction, wherein the inner opening has a circular cross-sectional shape.

[0037] like Figures 5c to 5d As shown in 6c to 6d, the outer surface 1a of the inner sleeve 1 is arranged to be related to the inner surface 2a of the outer sleeve 2, and when the inner sleeve 1 rotates relative to the outer sleeve 2, the outer surface 1a of the inner sleeve 1 moves relative to the inner surface 2a of the outer sleeve 2.

[0038] like Figures 4a to 4c As shown in 5a to 5b and 6a to 6b, an elongated slot 2c is arranged in the side wall structure 2d of the outer sleeve 2. The slot 2c extends from the inner surface 2a of the outer sleeve 2 through the side wall structure 2d of the outer sleeve 2 to the outer surface 2e of the outer sleeve 2, forming an opening from the outer surface 2e of the outer sleeve 2 to the inner sleeve 1.

[0039] As from Figures 4a to 4c As understood, the inner sleeve 1 includes an outer sleeve S extending from the inner sleeve 1 through the slot 2c to the outer sleeve 2. OThe locking member 6 is configured to releasably attach the inner sleeve 1 to the outer sleeve 2. In the unlocked state S U In the middle, the locking member 6 unlocks the inner sleeve 1 from the outer sleeve 2, thereby allowing the inner sleeve 1 to rotate and shift relative to the outer sleeve 2. In the locked state S L In this process, the locking member 6 locks the inner sleeve 1 to the outer sleeve 2 through frictional engagement between at least the locking member 6 and the outer sleeve 2, and prevents the inner sleeve 1 from rotating or shifting relative to the outer sleeve 2 through frictional engagement. Figures 5a to 5b and Figures 6a to 6b As shown, the inner sleeve 1 includes a threaded opening 1b, and the locking member 6 is arranged to engage with a screw in the threaded opening 1b. In the locked state S... L In the middle, the locking member 6 contacts the outer sleeve 2 to establish a frictional locking engagement that prevents relative movement between the inner sleeve 1 and the outer sleeve 2. In the locked state S... L In this configuration, the inner sleeve 1 and outer sleeve 2 thus rotate together with the arm structure A around the fastening device 3a as a common structure when the door D is displaced. The slot 2c, in the illustrated embodiment, has an elongated construction and extends through the sidewall structure 2d of the outer sleeve, thus forming an opening that allows access to the inner sleeve from the outside of the outer sleeve 2. In the unlocked state S... U In the process of inner sleeve 1 rotating relative to outer sleeve 2, locking member 6 is allowed to move along the slot. When inner sleeve 1 reaches the desired position relative to outer sleeve 2, locking member 6 is arranged in the locked state S. L This prevents the inner sleeve 1 from rotating or shifting relative to the outer sleeve 2. The locking member 6 can be arranged as a screw, extending from the inner sleeve 1 through a slot 2c to the outside of the outer sleeve 2. The locking member 6 screws into the threaded opening 1b of the inner sleeve 1 to unlock the inner sleeve 1 from the outer sleeve 2 and lock the inner sleeve 1 to the outer sleeve 2. With this configuration, as... Figure 4b As shown, locking and unlocking operations can be efficiently achieved from the outside of the outer sleeve 2 using tool T, which allows the locking member 6 to rotate between the locked and unlocked states.

[0040] like Figures 5a to 5dAs shown in 6a to 6d, the receiving opening 3 has an elongated structure and extends along a first axis A1 passing through the inner sleeve 1 in a first direction D1. In the illustrated embodiment, the receiving opening 3 has an inclined extension passing through the inner sleeve 1. The outer surface 1a of the inner sleeve 1 is arranged as a cylindrical surface, and the inner surface 2a of the outer sleeve 2 is arranged as a cylindrical surface, and when the inner sleeve 1 rotates relative to the outer sleeve 2, the inner sleeve 1 rotates about a second axis A2 extending in a second direction D2. The door tilting system S, by means of the inclined structure of the receiving opening 3 relative to the second axis A2, allows the first direction D1 of the receiving opening 3 relative to the outer sleeve 2 to be changed when the inner sleeve 1 rotates relative to the outer sleeve 2. Figures 5c to 5d and Figures 6c to 6d As understood, when the inner sleeve 1 rotates and shifts, the change in the first direction D1 of the receiving opening 3 relative to the outer sleeve 2 alters the tilt position between the door D and the arm structure A. The tilt position is defined as the angular relationship between the door D and the arm structure A, and is further defined by the angular relationship between the first axis A1 and the second axis A2. Figure 5c and 6c In the tilted position shown, door D is in the inward direction relative to arm structure A. I Tilting upwards, thus tilting the upper part of door D... U It is positioned closer to vehicle body structure B in the closed position. Figure 5d and 6d In the tilted position shown, door D is in the outward direction relative to arm structure A. O Tilting upwards, thus tilting the upper part of door D... U Positioned away from vehicle body structure B in the closed position.

[0041] The inner sleeve 1 is arranged to rotate relative to the outer sleeve 2 about a second rotation axis A2 extending in a second direction D2, and therefore the inner sleeve 1 rotates about the second rotation axis A2 when it rotates and shifts relative to the outer sleeve 2. The door tilting system S has a configuration in which the first direction D1 is different from the second direction D2, and therefore the first axis A1 is not parallel to the second axis A2. The directional difference between the first axis A1 and the second axis A2 allows the receiving opening 3 to change its first direction D1 relative to the outer sleeve 2 when the inner sleeve 1 rotates and shifts relative to the outer sleeve 2 about the second axis A2. Figures 5a to 5d In the embodiments shown in 6a to 6d, the outer surface 1a of the inner sleeve 1 is arranged as a cylindrical surface, and the inner surface 2a of the outer sleeve 2 is arranged as a cylindrical surface. The outer surface 1a of the inner sleeve 1 and the inner surface 2a of the outer sleeve 2 therefore extend in or substantially in a second direction D2, wherein the second direction D2 is different from the first direction D1. Figures 5a to 5d In the illustrated embodiment, the second direction D2 extends through the outer sleeve 2 in a straight configuration, and through this configuration, for example from... Figure 5b As understood, the inner opening 2b therefore has a straight extension that passes through the outer sleeve 2. Figures 6a to 6d In an alternative embodiment, the second direction D2 extends through the outer sleeve 2 in an inclined configuration, and through this configuration, as from... Figures 6a to 6d As understood, the inner opening 2b therefore has an inclined extension through the outer sleeve 2 to increase the tilting possibility. It should be understood that, depending on the design and construction of the door tilting system S, the inner opening 2b can tilt relative to the outer sleeve 2 and / or the arm structure A in any suitable direction.

[0042] In other alternative embodiments, not shown, the receiving opening 3 may alternatively be arranged with a straight extension through the inner sleeve 1, and the inner opening 2b may be arranged with an inclined extension through the outer sleeve 2.

[0043] In order to operate the door tilting system S and adjust the tilt position between the door D and the arm structure A, the locking member 6 is first arranged in the unlocked state S. U Unlock the inner sleeve 1 from the outer sleeve 2. Figure 4b In the illustrated embodiment, tool T is inserted into locking member 6, and by unscrewing locking member 6, locking member 6 is released from the locked state S. L Shift to unlocked state S U This allows for rotational displacement of the inner sleeve 1 relative to the outer sleeve 2. In the unlocked state S U In this configuration, the inner sleeve 1 can be rotated and displaced relative to the outer sleeve 2 to any suitable desired position P. D To achieve the correct tilt position, such as for example Figure 4a and 4c The position shown is such that when the inner sleeve 1 rotates relative to the outer sleeve 2, the outer end of the locking member 6 slides within the slot 2c, and the rotational displacement of the inner sleeve 1 relative to the outer sleeve 2 changes the first direction D1 of the receiving opening 3 relative to the outer sleeve 2. When the inner sleeve 1 has been displaced relative to the outer sleeve 2 to the desired position P... D At that time, by arranging the locking member 6 into the locked state S L The inner sleeve 1 is locked to the outer sleeve 2 to prevent the inner sleeve 1 from rotating or shifting relative to the outer sleeve 2. At the desired position P... D In the middle, tool T is inserted into locking member 6, and by screwing locking member 6 into inner sleeve 1, locking member 6 is released from the unlocked state S. U Shift to locked state S L This is to prevent the inner sleeve 1 from rotating or shifting relative to the outer sleeve 2. It is in the locked state S. L In this configuration, the locking member 6 can lock the inner sleeve 1 to the outer sleeve 2 by frictional engagement between at least the locking member 6 and the outer sleeve 2, thereby effectively preventing rotational displacement of the inner sleeve 1 relative to the outer sleeve 2.
