Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to an adjustable automobile cable mechanism. Background Art

[0002] In the prior art, car seats often use cables to pull the seat frame, front foot lock and other parts to achieve movement functions such as rotation. For example: See the attached Figure 1 and attached Figure 2 In a certain automobile seat structure, the front part of the seat frame 100 is locked on the vehicle body floor by the front foot lock 200, the output end of the cable 300 is connected to the front foot lock 200, and the input end of the cable 300 is connected to the rotation point 400 at the rear of the seat frame 100. As the seat frame 100 flips backward, the rotation point 400 rotates and pulls the input end of the cable 300, so that the output end of the cable 300 drives the front foot lock 200 to rotate into the seat frame 100 and rotates backward into the pit synchronously with the seat frame 100.

[0003] Since the rotation angle (about 60°) of the front foot lock 200 when it is retracted into the seat frame 100 is much smaller than the flipping angle (about 170°) of the seat frame 100, the movement stroke of the input end of the cable 300 is larger than the movement stroke of the output end, causing the cable 300 to be easily over-pulled or even broken during the pulling process, affecting the service life of the cable and the user experience of the car seat.

[0004] At present, cable compensators are usually used to solve the above technical problems. The cable compensators limit the cable tension through built-in springs to protect the cable from over-tension and breakage. However, the input and output ends of the cable have the same stroke, and the cable stroke is also limited by the extension and contraction stroke of the spring. It cannot meet the demand for using cables with larger strokes, and each cable compensator can only protect one cable from over-tension, which has great limitations in use.

[0005] Therefore, it is necessary to provide an adjustable automobile cable mechanism that can solve the problem in the prior art that the cable input end and the cable output end are easily damaged by over-tension when the movement strokes are inconsistent. Utility Model Content

[0006] In view of the above situation, the utility model provides an adjustable automobile cable mechanism, which can solve the problem in the prior art that the cable input end and the cable output end are easily damaged by over-tension when the movement strokes are inconsistent.

[0016] In an embodiment of the utility model, the first turntable and the second turntable are rotatably connected to the bracket via rivets, a torsion spring is connected between the rivet on the first turntable and the retaining ring, and the torsion spring applies a restoring force to the first turntable so that the clutch structure returns from the disengaged state to the coupled state.

[0017] In an embodiment of the utility model, the clutch structure includes a first arcuate tooth segment arranged on the first rotating disk and a second arcuate tooth segment arranged on the second rotating disk. The first arcuate tooth segment is meshed with the second arcuate tooth segment, so that the input motion mechanism and the output motion mechanism rotate synchronously.

[0018] In an embodiment of the utility model, the clutch structure also includes a first arcuate convex surface arranged on the first rotating disk and adjacent to the first arcuate tooth segment, and a first arcuate concave surface arranged on the second rotating disk and adjacent to the second arcuate tooth segment.

[0019] In an embodiment of the utility model, the clutch structure also includes a second arcuate concave surface arranged on the first rotating disk and adjacent to the first arcuate tooth segment, and a roller rotatably arranged on the second rotating disk and adjacent to the second arcuate tooth segment. The second arcuate concave surface cooperates with the roller to make the input motion mechanism and the output motion mechanism rotate synchronously.

[0020] In an embodiment of the utility model, the clutch structure also includes a second arcuate convex surface arranged on the side of the second arcuate concave surface away from the first arcuate tooth segment, the second arcuate convex surface is adjacent to the second arcuate concave surface, and the second arcuate convex surface rotates tangentially relative to the roller, so that the input motion mechanism can rotate relative to the output motion mechanism, and the output motion mechanism remains stationary.

[0021] In an embodiment of the utility model, the movable part of the input motion mechanism is configured as a slide plate that can slide relative to the bracket, and the movable part of the output motion mechanism is configured as a third turntable that can rotate relative to the bracket; a tension spring is connected between the slide plate and the bracket, and the tension spring applies a restoring force to the slide plate so that the clutch structure returns from the disengaged state to the coupled state.

[0022] In the embodiment of the utility model, a slide groove is arranged on the slide plate, and at least one guide pin is arranged on the bracket, and the at least one guide pin is inserted into the slide groove.

[0023] In an embodiment of the utility model, the clutch structure includes a straight tooth segment arranged on the slide and a third arc-shaped tooth segment arranged on the third turntable.

[0024] In an embodiment of the utility model, the clutch structure also includes a first engaging surface arranged on the slide plate and adjacent to the straight tooth segment, and a second engaging surface arranged on the third turntable and adjacent to the third arc-shaped tooth segment. The first engaging surface cooperates with the second engaging surface so that the input motion mechanism can slide relative to the output motion mechanism, and the output motion mechanism remains stationary.

[0025] The utility model adopts the above technical solution, so that it has the following beneficial effects:

[0026] (1) The utility model is provided with an input motion mechanism and an output motion mechanism. When the input motion mechanism and the output motion mechanism are meshed for transmission, the input cable and the output cable can move synchronously. The input motion mechanism and the output motion mechanism can move relative to each other, thereby realizing the relative motion of the input cable and the output cable, thus satisfying the motion requirements of both ends of the cable, effectively avoiding the problem of over-tensioning or even breaking of the cable due to the different motion strokes at the two ends of the cable, and having good adaptability and versatility to different mechanisms based on cable motion on automobiles.

[0027] (2) Since the utility model is provided with an input motion mechanism and an output motion mechanism, the synchronous motion stroke of the input motion mechanism and the output motion mechanism can be adjusted by the meshing tooth ratio between the first arc-shaped tooth segment and the second arc-shaped tooth segment, and the meshing tooth ratio between the straight tooth segment and the third arc-shaped tooth segment. It can match the different motion strokes at both ends of the cable, has a large adjustment range and high adjustment flexibility, and can meet the application requirements of different projects.

[0028] (3) Since the utility model is provided with an input cable hanging point, an input winding retaining ring, an output cable hanging point and an output winding retaining ring, the input cable hanging point and the output cable hanging point can meet the hanging connection of different numbers of input cables and output cables, and meet the movement requirements of different numbers of input mechanisms and output mechanisms. At the same time, the input winding retaining ring and the output winding retaining ring can provide guidance and winding space for the movement of the input cables and the output cables, thereby ensuring the movement stability of all cable input and output ends.

[0029] (4) Since the utility model is provided with a torsion spring and a tension spring, the input cable can be stretched and stored when it is pulled, and after the input cable is released, the elastic force is used to reset the input motion mechanism and drive the output motion mechanism to reset synchronously, so that the entire motion process is reversible. At the same time, the motion gap between the meshing teeth in the entire motion stroke can be eliminated to prevent abnormal noise. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0050] To facilitate understanding of the present invention, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0051] Please see attached Figure 3 , Attachment Fig.11 and attached Fig.15 , an adjustable automobile cable mechanism 500, comprising:

[0052] An input motion mechanism 2 and an output motion mechanism 3 movably mounted on the bracket 1;

[0053] At least one input cable 4 connected between the input motion mechanism 2 and the input mechanism;

[0054] At least one output cable 5 connected between the output motion mechanism 3 and the output mechanism;

[0055] A clutch structure, which is connected to the input motion mechanism 2 and the output motion mechanism 3 respectively and is configured to switch between a coupled state and a disengaged state;

[0056] When the clutch structure is in a coupled state, the input motion mechanism 2 can drive the output motion mechanism 3 to move synchronously, and when the clutch structure is in a disengaged state, the input motion mechanism 2 can move relative to the output motion mechanism 3, thereby enabling the input cable 4 and the output cable 5 to have different motion strokes.

[0057] The input motion mechanism 2 can move relative to the output motion mechanism 3 through the clutch structure in the disengaged state, thereby protecting the output cable 5 from over-tension when the input cable 4 is over-tensioned, thereby effectively avoiding the problem of over-tension damage when the input and output ends of the cable have inconsistent strokes.

[0058] Please see attached Figure 4 To Attachment Figure 5 , Attachment Fig.15 and attached Fig.17 As shown, the input motion mechanism 2 and the output motion mechanism 3 each include a movable part movably connected to the bracket 1, and both of the two movable parts are provided with cable hanging points, namely, an input cable hanging point 201 on the movable part of the input motion mechanism 2 and an output cable hanging point 301 on the movable part of the output motion mechanism 3, so that one end of the input cable 4 and the output cable 5 are connected to the movable part through the input cable hanging point 201 and the output cable hanging point 301 respectively.

[0059] Preferably, the input cable hanging point 201 can be a T-shaped hanging point, and a ring is set at the end of the input cable 4 connected to the input motion mechanism 2 and sleeved on the vertical section of the input cable hanging point 201. The length of the vertical section of the input cable hanging point 201 can be adjusted to achieve the hanging of one or more input cables 4, and different numbers of input cables 4 can be controlled.

[0060] There are usually two input cables 4, which can meet the setting of cables on both sides of the seat to ensure the movement synchronization and force uniformity of the mechanisms on both sides of the seat. Compared with traditional cable compensators, the utility model has good use flexibility and adaptability.

[0061] Preferably, the output cable hanging point 301 can be a T-shaped hanging point, and a ring is set at the end of the output cable 5 connected to the output motion mechanism 3 and sleeved on the vertical section of the output cable hanging point 301. The length of the vertical section of the output cable hanging point 301 can be adjusted to achieve the hanging of one or more output cables 5, and different numbers of output cables 5 can be controlled.

[0062] Preferably, a card slot can be provided on the bracket 1, and a leather case can be sleeved on the input cable 4 and the output cable 5, and the leather case can be clamped on the bracket 1 through the card slot, so as to facilitate the installation of the input cable 4 and the output cable 5 and their smooth pulling in the leather case, thereby ensuring the controllability of the movement trajectory of the input cable 4 and the output cable 5.

[0063] Please see attached Figure 3 To Attachment Figure 6 The movable part of the input motion mechanism 2 is set as a first turntable that can rotate relative to the bracket 1, and the movable part of the output motion mechanism 3 is set as a second turntable that can rotate relative to the bracket 1. The first turntable and the second turntable are both provided with retaining rings for winding the input cable 4 and the output cable 5 respectively.

[0064] The retaining ring on the first turntable is the input winding retaining ring 202. Preferably, the input winding retaining ring 202 can adopt a semicircular ring structure, which is used to wind the input cable 4 and can release the input cable 4 when rotating. The height of the input winding retaining ring 202 can be adaptively adjusted according to the number of input cables 4.

[0065] The retaining ring on the second turntable is the output winding retaining ring 302. Preferably, the output winding retaining ring 302 can adopt a semicircular ring structure, which is used to wind the output cable 5 and can release the output cable 5 when rotating. The height of the output winding retaining ring 302 can be adaptively adjusted according to the number of output cables 5.

[0066] Please see attached Figure 3 To Attachment Figure 6 The first turntable and the second turntable are rotatably connected to the bracket 1 through rivets, and a torsion spring 203 is connected between the rivet on the first turntable and the retaining ring. The torsion spring 203 applies a restoring force to the first turntable so that the clutch structure returns to the coupled state from the disengaged state.

[0067] Specifically, the first rotating disk is rotatably connected to the bracket 1 via a hanging spring rivet 204, and a torsion spring 203 is connected between the hanging spring rivet 204 and its input winding retaining ring 202. The second rotating disk is rotatably connected to the bracket 1 via a rivet 303.

[0068] When the input cable 4 pulls the input motion mechanism 2 to rotate, both ends of the restoring coil spring 203 are stretched and force is stored. After the input cable 4 is released, the elastic force of the restoring coil spring 203 can be used to reset the input motion mechanism 2 in the reverse direction and drive the output motion mechanism 3 to reset in the reverse direction. At the same time, the movement gap between the meshing teeth in the full stroke can also be eliminated to prevent abnormal noise.

[0069] The clutch structure can be implemented according to actual needs using but not limited to the following three structures:

[0070] Embodiment 1:

[0071] Please see attached Figure 3 To Attachment Figure 8 The clutch structure includes a first arc-shaped tooth segment 6 arranged on the first rotating disk and a second arc-shaped tooth segment 7 arranged on the second rotating disk. The first arc-shaped tooth segment 6 is meshed with the second arc-shaped tooth segment 7, so that the clutch structure is in a coupled state, and the input motion mechanism 2 rotates synchronously with the output motion mechanism 3.

[0072] Under the meshing transmission of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7, the rotation transmission function of the first rotating disk and the second rotating disk is realized, that is, the synchronous transmission function of the input motion mechanism 2 and the output motion mechanism 3 is realized.

[0073] The synchronous motion stroke of the input motion mechanism 2 and the output motion mechanism 3 can be adjusted by the gear ratio of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7. For example, if the gear ratio of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7 is 1:1, the rotation strokes of the input motion mechanism 2 and the output motion mechanism 3 are equal; if the gear ratio of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7 is 1:2, the motion stroke of the input motion mechanism 2 is twice the rotation stroke of the output motion mechanism 3; if the gear ratio of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7 is 2:1, the motion stroke of the output motion mechanism 3 is twice the rotation stroke of the input motion mechanism 2, and so on.

[0074] Preferably, the first arc-shaped tooth segment 6 can be set at the side edge, top edge or bottom edge of the turntable of the input motion mechanism 2, and the second arc-shaped tooth segment 7 can be set at the side edge, top edge or bottom edge of the turntable of the output motion mechanism 3, and can be adaptively adjusted according to the actual installation space.

[0075] Please see attached Figure 3 To Attachment Figure 8 The clutch structure also includes a first arcuate convex surface 8 disposed on the first rotating disk and adjacent to the first arcuate tooth segment 6, and a first arcuate concave surface 9 disposed on the second rotating disk and adjacent to the second arcuate tooth segment 7. The first arcuate convex surface 8 and the arcuate concave surface 9 are in contact with each other, so that the clutch structure is in a disengaged state, and the input motion mechanism 2 can rotate relative to the output motion mechanism 3, and the output motion mechanism 3 remains stationary.

[0076] After the meshing transmission of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7 is completed, the output motion mechanism 3 stops moving due to the contact between the first arc-shaped convex surface 8 and the first arc-shaped concave surface 9, but the input motion mechanism 2 can still rotate relative to the output motion mechanism 3, so that the input cable 4 and the output cable 5 can have different motion strokes. Further, the motion stroke of the input cable 4 can be greater than the motion stroke of the output cable 5, or the motion stroke of the input cable 4 can be less than the motion stroke of the output cable 5 by setting the gear ratio of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7, and / or the arc length of the first arc-shaped convex surface 8.

[0077] Preferably, the first arcuate convex surface 8 can be integrally formed with the first arcuate tooth segment 6, the outer ring of the first arcuate convex surface 8 is a convex arcuate structure, the first arcuate concave surface 9 can be integrally formed with the second arcuate tooth segment 7, the outer ring of the first arcuate concave surface 9 is a concave arcuate structure, so that the relative sliding of the first arcuate concave surface 9 and the first arcuate convex surface 8 is achieved through the matching and fitting of the concave and convex surfaces, and the rotation of the first arcuate concave surface 9 is limited by the first arcuate convex surface 8. The center of the first arcuate convex surface 8 coincides with the center of the first rotating disk, and the convex shape and curvature of the first arcuate convex surface 8 can be fine-tuned according to actual use requirements.

[0078] Please see attached Figure 3 To Attachment Figure 8 , the motion process and working principle of Example 1 are:

[0079] The input cable 4 is transmitted with a pulling force through an input mechanism such as a physical switch (such as a wrench) or a motor or a moving part, so that the input cable 4 drives the input motion mechanism 2 to rotate counterclockwise as shown in the figure around the hanging spring rivet 204 through the input cable hanging point 201. While the input motion mechanism 2 rotates, the first arc-shaped tooth segment 6 rotates synchronously with the input motion mechanism 2, and meshes with the second arc-shaped tooth segment 7, so that the second arc-shaped tooth segment 7 drives the output motion mechanism 3 to rotate clockwise as shown in the figure, and the output cable 5 applies a pulling force to the output mechanism, thereby realizing the motion functions such as the rotation of the output mechanism.

[0080] As the input cable 4 is pulled, after the first arcuate tooth segment 6 and the second arcuate tooth segment 7 are transmitted from the first meshing tooth to the last meshing tooth, the first arcuate concave surface 9 and the first arcuate convex surface 8 slide and fit, so that the input motion mechanism 2 can continue to rotate, while the output motion mechanism 3 is limited by the sliding contact between the first arcuate concave surface 9 and the first arcuate convex surface 8 and cannot continue to rotate, the output cable 5 completes the motion stroke, and the input cable 4 can still continue to move, so that the motion stroke of the output cable 5 is inconsistent with the motion stroke of the output cable 4.

[0081] Please see attached Fig. 9 and attached Fig.10 In the car seat structure, the middle part of the cable is disconnected and the automobile cable adjustment mechanism 500 of the utility model is connected at the disconnection point, and the cable is divided into an output cable 5 connected to the front foot lock 200 (i.e., the output mechanism) and an input cable 4 connected to the rotation point 400 (i.e., the input mechanism) at the rear of the seat frame 100.

[0082] According to the input rotation stroke of the rotation point 400 and the output rotation stroke requirements of the front foot lock 200, the diameter of the first arc-shaped tooth segment 6 is made larger than the diameter of the second arc-shaped tooth segment 7, and the length of the first arc-shaped convex surface 8 is much larger than the size of the first arc-shaped concave surface 9. When the rotation point 400 at the rear of the seat frame 100 rotates and pulls the input cable 4, during the meshing transmission process between the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7, the linkage output cable 5 drives the front foot lock 200 to rotate and be retracted into the seat frame 100. When the first arc-shaped concave surface 9 contacts the first arc-shaped convex surface 8 and slides relative to the first arc-shaped convex surface 8, the front foot lock 200 no longer rotates, and the rotation point 400 at the rear of the seat frame 100 can continue to rotate as the seat frame 100 flips backward, ensuring that the seat frame 100 can flip backward at a large angle into the pit. In this process, problems such as over-pulling and breakage of the cable caused by inconsistent travel at both ends of the cable can be effectively avoided.

[0083] In other cable transmission structures, different movement stroke controls of the input cable 4 and the output cable 5 can be achieved by adjusting the gear ratio of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7 .

[0084] During the above movement, both ends of the torsion spring 203 are stretched to store force; after the input mechanism is released, the elastic force of the torsion spring 203 is used to drive the input motion mechanism 2 to rotate counterclockwise to reset. During the reset process, the first arcuate convex surface 8 and the first arcuate concave surface 9 first slide relative to each other, so that the input motion mechanism 2 rotates relative to the output motion mechanism 3 until the first arcuate tooth segment 6 and the second arcuate tooth segment 7 are meshed; then, the input motion mechanism 2 and the output motion mechanism 3 are synchronously rotated and reset through the meshing transmission of the first arcuate tooth segment 6 and the second arcuate tooth segment 7, and the output mechanism is reset under the pulling of the output cable 5.

[0085] Embodiment 2:

[0086] Please see attached Fig.11 To Attachment Fig.14 The clutch structure includes a first arc-shaped tooth segment 6 arranged on the first rotating disk and a second arc-shaped tooth segment 7 arranged on the second rotating disk. The first arc-shaped tooth segment 6 is meshed with the second arc-shaped tooth segment 7 to make the input motion mechanism 2 and the output motion mechanism 3 rotate synchronously.

[0087] The meshing transmission process between the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7 in Embodiment 2 is the same as that in Embodiment 1, and will not be described again.

[0088] The clutch structure also includes a second arcuate concave surface 15 arranged on the first rotating disk and adjacent to the first arcuate tooth segment 6, and a roller 14 rotatably arranged on the second rotating disk and adjacent to the second arcuate tooth segment 7. The second arcuate concave surface 15 cooperates with the roller 14 to put the clutch structure in a coupled state, and the input motion mechanism 2 and the output motion mechanism 3 rotate synchronously.

[0089] Preferably, the second arc-shaped concave surface 15 can be designed to be an arc shape matching the roller 14 for embedding the roller 14 .

[0090] The clutch structure also includes a second arcuate convex surface 12 arranged on the side of the second arcuate concave surface 15 away from the first arcuate tooth segment 6. The second arcuate convex surface 12 is adjacent to the second arcuate concave surface 15. The second arcuate convex surface 12 rotates tangentially relative to the roller 14, so that the clutch structure is in a disengaged state. The input motion mechanism 2 can rotate relative to the output motion mechanism 3, and the output motion mechanism 3 remains stationary.

[0091] The center of the second arcuate convex surface 12 coincides with the center of the first rotating disk, so that the roller 14 is circumscribed to the second arcuate convex surface 12. The curved surface direction of the second arcuate concave surface 15 is opposite to that of the second arcuate convex surface 12, in order to avoid the roller 14.

[0092] After the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7 are meshed and driven, and the second arc-shaped concave surface 15 and the roller 14 are matched, the output motion mechanism 3 stops moving by the tangential rotation of the roller 14 on the second arc-shaped convex surface 12, but the input motion mechanism 2 can still rotate relative to the output motion mechanism 3, so that the input cable 4 and the output cable 5 can have different motion strokes. Further, by setting the gear ratio of the first arc-shaped tooth segment 6 and the second arc-shaped tooth segment 7, and / or the arc length of the first arc-shaped convex surface 8, the motion stroke of the input cable 4 can be greater than the motion stroke of the output cable 5, or the motion stroke of the input cable 4 can be less than the motion stroke of the output cable 5.

[0093] Compared with Example 1, Example 2 can convert the sliding friction between the first arcuate convex surface 8 and the first arcuate concave surface 9 into rolling friction between the roller 14 and the second arcuate convex surface 12, thereby reducing the friction resistance and making the input motion mechanism 2 continue to move more smoothly.

[0094] Please see attached Fig.11 To Attachment Fig.14 , the motion process and working principle of Example 2 are:

[0095] The input cable 4 is transmitted with a pulling force through an input mechanism such as a physical switch (such as a wrench) or a motor or a moving part, so that the input cable 4 drives the input motion mechanism 2 to rotate counterclockwise as shown in the figure around the hanging spring rivet 204 through the input cable hanging point 201. While the input motion mechanism 2 rotates, the first arc-shaped tooth segment 6 rotates synchronously with the input motion mechanism 2, and meshes with the second arc-shaped tooth segment 7, so that the second arc-shaped tooth segment 7 drives the output motion mechanism 3 to rotate clockwise as shown in the figure, and the output cable 5 applies a pulling force to the output mechanism, thereby realizing the motion functions such as the rotation of the output mechanism.

[0096] As the input cable 4 is pulled, after the first arcuate tooth segment 6 and the second arcuate tooth segment 7 are transmitted from the first meshing tooth to the last meshing tooth, the roller 14 rolls through the second arcuate concave surface 15 and rolls tangentially with the second arcuate convex surface 12, so that the input motion mechanism 2 can continue to rotate, while the output motion mechanism 3 cannot continue to rotate due to the rolling contact between the roller 14 and the second arcuate convex surface 12, the output cable 5 completes the motion stroke, and the input cable 4 can still continue to move, so that the motion stroke of the output cable 5 is inconsistent with the motion stroke of the output cable 4.

[0097] The automobile cable adjustment mechanism 500 of Example 2 can also be applied to an automobile seat structure. Its installation position and movement process are the same as those of Example 1 and will not be described in detail here.

[0098] During the above movement, both ends of the torsion spring 203 are stretched to store force; after the input mechanism is released, the elastic force of the torsion spring 203 is used to drive the input motion mechanism 2 to rotate counterclockwise to reset. During the reset process, the roller 14 first rolls with the second arcuate convex surface 12 to rotate the input motion mechanism 2 relative to the output motion mechanism 3 until the first arcuate tooth segment 6 and the second arcuate tooth segment 7 are meshed; then, the input motion mechanism 2 and the output motion mechanism 3 are synchronously rotated and reset through the meshing transmission of the first arcuate tooth segment 6 and the second arcuate tooth segment 7, and the output mechanism is reset under the pulling of the output cable 5.

[0099] Embodiment 3:

[0100] Please see attached Fig.15 To Attachment Fig.18 The movable part of the input motion mechanism 3 is configured as a slide plate that can slide relative to the bracket 1, and the movable part of the output motion mechanism 3 is configured as a third turntable that can rotate relative to the bracket 1; a tension spring 206 is connected between the slide plate and the bracket 1, and the tension spring 206 applies a restoring force to the slide plate so that the clutch structure returns to the coupled state from the disengaged state.

[0101] The slide plate is provided with a slide groove 207, and the bracket 1 is provided with at least one guide pin, and the at least one guide pin is inserted into the slide groove 207. It can be understood that there are many ways for the slide plate to slide relative to the bracket, which are not limited to the one in this embodiment. The slide plate and the bracket 1 can also be replaced by the upper rail and the lower rail of the slide rail mechanism respectively.

[0102] Preferably, the input motion mechanism 2 can adopt a rectangular slide plate, and the long strip slide groove 207 is used to install the input motion mechanism 2 on the bracket 1, and the input motion mechanism 2 can move linearly along the slide groove 207 relative to the bracket 1. When the guide pin slides along the slide groove 207 with the input motion mechanism 2 and contacts the end of the slide groove 207, the movement of the input motion mechanism 2 on the bracket 1 can be limited.

[0103] The center of the third turntable of the output motion mechanism 3 is mounted on the bracket 1 through the rivet 303 and can rotate around the rivet 303, so that the transmission requirements between the input cable 4 and the output cable 5 are met through the movement of the input motion mechanism 2 and the rotation of the output motion mechanism 3.

[0104] The clutch structure includes a spur tooth segment 16 disposed on the slide plate and a third arc-shaped tooth segment 17 disposed on the third rotating disk. The spur tooth segment 16 meshes with the third arc-shaped tooth segment 17 to enable the input motion mechanism 2 and the output motion mechanism 3 to move synchronously.

[0105] The meshing of the spur tooth segment 16 and the third arc-shaped tooth segment 17 realizes the linkage meshing transmission and synchronous motion of the input motion mechanism 2 and the output motion mechanism 3. The synchronous motion stroke and motion speed of the input motion mechanism 2 and the output motion mechanism 3 can be adjusted by the length of the spur tooth segment 16 and the diameter of the third arc-shaped tooth segment 17.

[0106] Please see attached Fig.15 To Attachment Fig.18 The clutch structure also includes a first engagement surface 18 disposed on the slide plate and adjacent to the spur tooth segment 16, and a second engagement surface 19 disposed on the third rotating disk and adjacent to the third arc-shaped tooth segment 17. The first engagement surface 18 and the second engagement surface 19 cooperate to allow the input motion mechanism 2 to slide relative to the output motion mechanism 3, and the output motion mechanism 3 remains stationary.

[0107] After the meshing transmission between the spur tooth segment 16 and the third arc-shaped tooth segment 17 is completed, the relative movement of the input motion mechanism 2 and the output motion mechanism 3 is achieved through the relative sliding cooperation of the first joint surface 18 and the second joint surface 19, which can meet the use requirements of inconsistent motion strokes of the input cable and the output cable.

[0108] Preferably, the spur tooth segment 16 and the first joint surface 18 can be integrally formed with the slide plate, the third arc-shaped tooth segment 17 and the second joint surface 19 can be integrally formed with the output motion mechanism 3, and the first joint surface 18 and the second joint surface 19 can be planes. After the meshing transmission of the third arc-shaped tooth segment 17 and the spur tooth segment 16 is completed, the first joint surface 18 and the second joint surface 19 are in sliding contact to achieve the stopping of the output motion mechanism 3, while the input motion mechanism 2 can continue to move, and the stroke of the input motion mechanism 2 continuing to move can be adjusted by the length of the first joint surface 18 and the second joint surface 19.

[0109] Please see attached Fig.15 An extension plate 205 may be formed at the bottom of the slide plate of the input motion mechanism 2 , one side of the extension plate 205 is connected to the input cable 4 through the input cable hanging point 201 , and a tension spring 206 is connected between the other side of the extension plate 205 and the bracket 1 .

[0110] When the input cable 4 is pulled and moves, the input motion mechanism 2 slides to stretch the tension spring 206 to store force. Therefore, after the input cable 4 is released, the tension of the tension spring 206 can be used to provide reverse pulling to the input motion mechanism 2 to make it slide and reset, and the output motion mechanism 3 can be linked to the input motion mechanism 2 to make it rotate and reset. At the same time, the movement gap between the meshing teeth in the full stroke can also be eliminated to prevent abnormal noise.

[0111] Please see attached Fig.15 To Attachment Fig.18 , the motion process and working principle of Example 3 are:

[0112] The pulling force is transmitted to the input cable 4 through an input mechanism such as a physical switch (wrench) or a motor or a moving part, so that the input cable 4 drives the input motion mechanism 2 to move along the slide groove 207 along the straight line on the left side of the figure through the input cable hanging point 201. When the input motion mechanism 2 moves, the straight tooth segment 16 moves synchronously with the input motion mechanism 2 and meshes with the third arc-shaped tooth segment 17, so that the third arc-shaped tooth segment 17 drives the output motion mechanism 3 to rotate clockwise as shown in the figure, and the output cable 5 applies a pulling force to the output mechanism, thereby realizing the rotation and other motion functions of the output mechanism.

[0113] As the input cable 4 is pulled, the straight tooth segment 16 and the third arc-shaped tooth segment 17 are transmitted from the first meshing tooth to the last meshing tooth, and the second joint surface 19 and the first joint surface 18 are in sliding contact, so that the input motion mechanism 2 can continue to move, while the output motion mechanism 3 is restricted by the sliding contact between the second joint surface 19 and the first joint surface 18 and cannot continue to rotate, the output cable 5 completes the movement stroke, and the input cable 4 can still continue to move, so that the movement stroke of the output cable 5 is inconsistent with the movement stroke of the output cable 4.

[0114] The automobile cable adjustment mechanism 500 of Example 3 can also be applied to an automobile seat structure. Its installation position is the same as that of Example 1 and Example 2, and will not be described again here.

[0115] During the above movement, the tension spring 206 is stretched and force is accumulated; after the input mechanism is released, the elastic force of the tension spring 206 is used to drive the input motion mechanism 2 to slide and reset relative to the bracket 1 through the slide groove 207. During the reset process, the second joint surface 19 and the first joint surface 18 first slide in contact, so that the input motion mechanism 2 moves relative to the output motion mechanism 3 until the straight tooth segment 16 and the third arc-shaped tooth segment 17 are engaged; then, the input motion mechanism 2 and the output motion mechanism 3 are synchronously driven and reset through the meshing transmission of the straight tooth segment 16 and the third arc-shaped tooth segment 17, and the reset of the output mechanism is realized under the pulling of the output cable 5.

[0116] The utility model is described in detail above with reference to the accompanying drawings and embodiments. A person skilled in the art can make various variations of the utility model according to the above description. Therefore, certain details in the embodiments should not constitute a limitation of the utility model, and the scope of protection of the utility model shall be defined by the scope of the attached claims.
