Description

Technical Field

[0001] This disclosure relates to a linear locking mechanism for steplessly locking an elongated first member having a longitudinal extension to a second member. The first member is releasably connected to the second member and is capable of linear movement relative to the second member in a first longitudinal direction and a second longitudinal direction opposite to the first longitudinal direction. This disclosure also relates to a vehicle component including the linear locking mechanism, and a method of operating the linear locking mechanism. Background Technology

[0002] Linear locking mechanisms for steplessly locking an elongated first component to a second component have been used in many different applications where the relative positions of two components need to be adjusted and then locked together. In vehicle applications, linear locking mechanisms can be used, for example, to adjust and lock vehicle seats to a track structure, or as part of a vehicle seat structure, to adjust and lock the relative positions of seat components. This locking configuration prevents relative translational movement between the components.

[0003] Stepless locking enables efficient locking without the need for locking grooves or similar structures. Traditionally, such linear locking mechanisms have been complex to construct, thus requiring simpler designs suitable for different vehicle applications. Summary of the Invention

[0004] The purpose of this disclosure is to provide a linear locking mechanism, a vehicle component including the linear locking mechanism, and a method of operating the linear locking mechanism to solve the aforementioned problems. This purpose is achieved at least in part by the features of the independent claims. The dependent claims contain further improvements to the linear locking mechanism and the vehicle component.

[0005] This disclosure relates to a linear locking mechanism for steplessly locking an elongated first member having an extension in the longitudinal direction to a second member. The first member is releasably connected to the second member and is linearly movable relative to the second member in a first longitudinal direction and a second longitudinal direction opposite to the first longitudinal direction. The linear locking mechanism includes a first locking device comprising a first locking member and a second locking member disposed around the outer surface of the first member and connected to the second member. The first locking member applies a first locking force to the first member to prevent movement therein in the first longitudinal direction; the second locking member applies a second locking force to the first member to prevent movement therein in the second longitudinal direction. The first locking member is biased by a first spring in the first longitudinal direction to a first inclined position relative to the extension of the first member in the longitudinal direction to form the first locking force; the second locking member is biased by a second spring in the second longitudinal direction to a second inclined position relative to the extension of the first member in the longitudinal direction to form the second locking force.

[0006] The advantage of these features is that the linear locking mechanism can be simplified and made more efficient through the design of the first and second locking elements. The locking elements enable efficient stepless locking between the first and second components and prevent relative translational movement between the components during locking. Two locking forces ensure that the first component is locked in opposite longitudinal directions relative to the second component. Stepless locking prevents the two components from being incorrectly locked in a semi-locked state, such as between two steps. In this semi-locked state, the load applied to the two components could cause them to separate from each other uncontrollably.

[0007] In one embodiment, the first locking member includes a first opening defined by a first inner edge face through which the first member extends. The first inner edge face is configured to apply a first locking force when frictionally engaged between the first inner edge face and an outer surface of the first member. The second locking member includes a second opening defined by a second inner edge face through which the first member extends. The second inner edge face is configured to apply a second locking force when frictionally engaged between the second inner edge face and an outer surface of the first member. The edge faces are used to effectively clamp the first member to apply the locking force.

[0008] In one embodiment, the linear locking mechanism includes a first support structure arranged around a first member. The first support structure is arranged to contact a first locking member. The linear locking mechanism also includes a second support structure arranged around the first member. The second support structure is arranged to contact a second locking member. The support structures respectively support the locking function of the first and second locking members to effectively lock the first member to the second member.

[0009] In one embodiment, the first support structure includes a first abutment arranged to contact a first outer edge of the first locking member, wherein the first abutment is configured to position the first locking member relative to the longitudinal extension of the first member in a first inclined position when the first locking member is biased by a first spring in a first longitudinal direction. The second support structure includes a second abutment arranged to contact a second outer edge of the second locking member, wherein the second abutment is configured to position the second locking member relative to the longitudinal extension of the first member in a second inclined position when the second locking member is biased by a second spring in a second longitudinal direction. The abutments allow the first and second locking members to be in inclined positions, thereby creating a strong clamping action between each locking member and the first member, preventing movement of the first member relative to the second member.

[0010] In one embodiment, the linear locking mechanism further includes a second locking device. The second locking device includes an outer locking member arranged around the first member, and one or more inner locking members arranged at least partially within the outer locking member and connected to the first member. The one or more inner locking members are movably arranged relative to the first member and the outer locking member in a longitudinal direction. The one or more inner locking members are configured to apply a third locking force to the first member to prevent movement of the first member relative to the second member in a first longitudinal direction and a second longitudinal direction. With this configuration, the linear locking mechanism has a two-part locking device, wherein the first locking device provides an initial locking force and the second locking device provides a high-load locking force. This is suitable in structures requiring a higher locking force. The first and second locking devices effectively cooperate to generate a locking force that prevents movement of the first member relative to the second member.

[0011] In one embodiment, one or more inner locking members are configured to apply a third locking force to the first member to prevent the first member from moving relative to the second member in the longitudinal first direction and the longitudinal second direction when the outer locking member moves relative to the one or more inner locking members in the longitudinal direction, and / or when the one or more inner locking members move relative to the outer locking members in the longitudinal direction.

[0012] In one embodiment, during relative movement of the outer locking member toward one or more inner locking members in the longitudinal direction, and / or during relative movement of one or more inner locking members toward the outer locking member in the longitudinal direction, the one or more inner locking members are configured to be pushed toward the outer surface of the first member to apply a third locking force through frictional engagement between the one or more inner locking members and the outer surface of the first member.

[0013] In one embodiment, the outer locking member has a frustoconical inner surface. One or more inner locking members each have an inner surface arranged to contact the outer surface of the first member, and an inclined outer surface arranged to contact the inner surface of the outer locking member. The inner surfaces of the one or more inner locking members are configured to apply a third locking force through frictional engagement between the inner surfaces of the one or more inner locking members and the outer surface of the first member. The interaction between the frustoconical inner surface of the outer locking member and the inclined outer surfaces of the one or more inner locking members pushes the one or more inner locking members toward the first member as the outer locking member and the one or more inner locking members move relative to each other.

[0014] In one embodiment, the first support structure is movably arranged relative to the first member. When a first locking force is applied to the first member, the first locking member is configured to push the first support structure and one or more inner locking members toward the outer locking member in a longitudinal first direction to apply a third locking force to the first member; or when the first locking force is applied to the first member, the first locking member is configured to push the first support structure and the outer locking member toward one or more inner locking members in a longitudinal first direction to apply a third locking force to the first member. The movable arrangement of the first support structure allows the first locking device and the second locking device to cooperate, wherein the first locking device and the second locking device effectively cooperate to generate a locking force that prevents movement of the first member relative to the second member.

[0015] In one embodiment, the second support structure is movably arranged relative to the first member. When a second locking force is applied to the first member, the second locking member is configured to push the second support structure and the outer locking member toward one or more inner locking members in a second longitudinal direction to apply a third locking force to the first member; or when a second locking force is applied to the first member, the second locking member is configured to push the second support structure and one or more inner locking members toward the outer locking member in a second longitudinal direction to apply a third locking force to the first member. The movable arrangement of the second support structure allows the first locking device and the second locking device to cooperate, wherein the first locking device and the second locking device effectively cooperate to generate a locking force that prevents movement of the first member relative to the second member.

[0016] In one embodiment, the second locking device includes a third spring disposed between an outer locking member and one or more inner locking members. The outer locking member and the one or more inner locking members are configured to be biased away from each other in the longitudinal direction by the third spring. The third spring enables the second locking device to be in an unlocked position when no force is applied.

[0017] In one embodiment, the first locking device is arranged in a housing structure connected to the second component, and / or the first locking device and the second locking device are arranged in a housing structure connected to the second component.

[0018] In one embodiment, the linear locking mechanism further includes an unlocking mechanism. The unlocking mechanism is configured to unlock the first locking device, enabling linear movement of the first member relative to the second member by releasing a first locking force and a second locking force. Alternatively, the unlocking mechanism is configured to unlock both the first and second locking devices, enabling linear movement of the first member relative to the second member by releasing a first locking force, a second locking force, and a third locking force.

[0019] This disclosure also relates to vehicle components that include the aforementioned linear locking mechanism.

[0020] In some embodiments, the vehicle component is a vehicle seat track structure or a vehicle component is a seat body structure.

[0021] This disclosure also relates to a method of operating the above-described linear locking mechanism. The method includes the following steps: applying a first locking force to a first member via a first locking member to prevent movement of the first member relative to a second member in a longitudinal first direction, wherein the first locking member is biased by a first spring along the longitudinal first direction to a first inclined position relative to an extension of the first member in the longitudinal direction, thereby establishing the first locking force; and applying a second locking force to the first member via a second locking member to prevent movement of the first member relative to the second member in a longitudinal second direction, wherein the second locking member is biased by a second spring along the longitudinal second direction to a second inclined position relative to an extension of the first member in the longitudinal direction, thereby establishing the second locking force.

[0022] The advantage of this method lies in the fact that the design of the first and second locking elements allows for a simple and efficient construction of the linear locking mechanism. These locking elements enable effective stepless locking between the first and second components and prevent relative translational movement between the components during locking. Two locking forces ensure that the first component is locked relative to the second component in opposite longitudinal directions. Stepless locking prevents the two components from being incorrectly fixed together in a semi-locked state, such as between two positions. In this semi-locked state, the load applied to the two components may cause them to separate from each other in an uncontrolled manner. Attached Figure Description

In the illustrated embodiment, the first locking device L1 is arranged in a housing structure H connected to the second member 2.

[0038] The first locking element 3a is in the locked state. L The configuration is to apply a first locking force F1 to the first member 1 to prevent the first member 1 from being in the longitudinal first direction D relative to the second member 2. L1 Move upwards, such as Figure 3 As indicated by the arrow in the diagram.

Locked state S L exist Figure 3 and Figure 5b The image is shown schematically.

[0039] The first locking member 3a includes a first opening 5a defined by a first inner edge surface 6a through which the first member 1 extends. The first opening 5a is suitably slightly larger than the cross-sectional dimension of the first member 1. When the first inner edge surface 6a frictionally engages with the outer surface 1a of the first member 1, the first inner edge surface 6a applies a first locking force F1. In the illustrated embodiment, the first locking member 3a is arranged as an annular structure extending around the outer surface 1a of the first member 1, and the first locking member 3a suitably has a washer-like construction. The first locking member 3a is made of a robust material capable of interacting with the outer surface 1a of the first member 1, for applying a locking force F1 to prevent the first member 1 from engaging in the longitudinal first direction D.

Similarly, due to the first inclined position P of the first locking member 3a...

It should be understood that the terms "upper" and "lower" are relative to... Figure 3 and Figure 5bThe position of the linear locking mechanism M shown is used to illustrate the details of the linear locking mechanism M.

[0042] like Figure 3 and Figure 5b As shown, in order to make the first locking member 3a be in the first tilted position P I1 The first locking member 3a is connected to the first spring 4a along the longitudinal first direction D. L1 Offset relative to the first member 1 in the longitudinal direction D LO The upper extension is in the first inclined position P I1 This generates a first locking force F1. In this way, the first spring 4a is used to push the first locking member 3a to the first tilt position P by means of the elastic force acting on a portion of the first locking member 3a. I1 In the position of the linear locking mechanism M shown, the first spring 4a acts on the lower part of the first locking member 3a.

[0043] from Figure 3 It is understood that the linear locking mechanism M includes a first support structure 7a that at least partially surrounds the first member 1. The first support structure 7a is arranged in contact with the first locking member 3a for positioning the first locking member 3a in a first inclined position P. I1 When the elastic force of the first spring 4a acts on the first locking member 3a, the first support structure 7a prevents the first locking member 3a from moving along the first member 1 in the longitudinal direction D.

L2 Offset, relative to the first component 1 in the longitudinal direction D LO The extension on top is in the second inclined position P I2 This generates a second locking force F2. In this way, the second spring 4b is used to push the second locking member 3b to the second tilt position P by means of the spring force acting on a portion of the second locking member 3b.

I2 When the elastic force of the second spring 4b acts on the second locking member 3b, the second support structure 7b prevents the second locking member 3b from moving longitudinally along the first member 1. LO The first component 1 moves upward. In this embodiment, the second support structure 7b is appropriately fixed relative to the second component 2 and connected to the second component 2 to achieve effective locking between the first component 1 and the second component 2.

In this embodiment, the linear locking mechanism M includes a first locking device L1 as described in the previous embodiment, and a further second locking device L2. With this configuration, the linear locking mechanism M has two locking parts, wherein the first locking device L1 provides an initial locking force and the second locking device L2 provides a high-load locking force. Compared to the embodiment described above which only has a first locking device L1, this embodiment of the linear locking mechanism M is suitable for configurations requiring a higher locking force. The first locking device L1 and the second locking device L2 cooperate to generate a locking force to prevent the first member 1 from moving relative to the second member 2. The first locking device L1 and the second locking device L2 are arranged in a housing structure H connected to the second member 2.

In the illustrated embodiment, it can be understood from the figures that the outer locking member 9a and the one or more inner locking members 9b are longitudinally arranged between the first locking member 3a and the second locking member 3b. The one or more inner locking members 9b are positioned in the longitudinal direction D... LO The upper part is movably arranged relative to the first member 1 and the outer locking member 9a. One or more inner locking members 9b are configured to apply a third locking force F3 to the first member 1 to prevent the first member 1 from being in the longitudinal first direction D relative to the second member 2. L1 and the second longitudinal direction D L2 Move upwards. When the outer locking member 9a is in the longitudinal direction DLO When moving relative to one or more inner locking members 9b, and / or when one or more inner locking members 9b are in the longitudinal direction D LO When the upper part moves relative to the outward locking member 9a, a third locking force F3 is applied. Figures 8a-8b In the illustrated embodiment, three inner locking elements 9b are used to apply the third locking force F3. However, it should be understood that the second locking device L2 may have any suitable number of inner locking elements 9b.

LO The relative movement of the components will cause each of the one or more inner locking members 9b to generate a radial displacement toward the outer surface 1a of the first member 1. This radial displacement pushes each of the one or more inner locking members 9b toward the first surface 1a to apply a third locking force F3 to the first member 1.

Each of the one or more inner locking members 9b has an inclined outer surface 11b arranged to contact the inner surface 10 of the outer locking member 9a. Thus, the inner surfaces 11a of the one or more inner locking members 9b are configured to apply a third locking force F3 through frictional engagement between the inner surfaces 11a of the one or more inner locking members 9b and the outer surface 1a of the first member 1. When the outer locking member 9a and the one or more inner locking members 9b are in the longitudinal direction D... LOWhen the upper parts move relative to each other, the interaction between the frustoconical inner surface 10 of the outer locking member 9a and the inclined outer surface 11b of one or more inner locking members 9b pushes one or more inner locking members 9b toward the first member 1.

LO The upper part moves relative to the first component 1 and the second component 2. The first support structure 7a and the second support structure 7b move in the longitudinal direction D.

L1 Move upwards. It should be understood that during the locking operation, the first component 1 moves only in the longitudinal first direction D.

L1 ) biased relative to the first member (1) in the longitudinal direction (D LO The first inclined position of the extension on the ) (P) I1 ), to generate the first locking force (F1); A second locking force (F2) is applied to the first member (1) by the second locking member (3b) to prevent the first member (1) from moving relative to the second member (2) in the longitudinal second direction (D). L2 The second locking member (3b) is moved along the longitudinal second direction (D) by the second spring (4b). L2 ) biased relative to the first member (1) in the longitudinal direction (D LO The second inclined position of the extension on ) (P) I2 ), to generate the second locking force (F2).
