Slidable device for a track

Abstract

The present disclosure provides a slidable device for a track, which includes a manual operating part, a rotating part, a connecting rod part, and a locking part. The manual operating part is operable to rotate between a locking position and an unlocking position. The rotation of the manual operating part drives the rotating part to rotate about its axis. The rotation of the rotating part drives the connecting rod part to move, and in turn drives the locking part to rotate. When the manual operating part is in the locking position, the locking part is in a locked state to restrict the movement of the locking part relative to the track, thereby locking the device on the track. When the manual operating part is in the unlocking position, the locking part is in an unlocked state due to the separation from the track, thereby allowing the locking part to move relative to the track. A user can adjust the position of the slidable device on the track as needed, and make X-direction adjustment. Furthermore, the design of such transmission mechanism is more compact, and the processing cost is lower.

Description

Technical Field

[0001] This disclosure relates to the field of precision machinery technology, and more specifically to a sliding device for a track. Background Technology

[0002] As the automotive consumer market continues to demand higher levels of driving comfort and functionality, the practical design of in-car auxiliary products has become a key focus of industry research and development. Among these, in-car tray tables are a crucial component for improving the convenience of passengers for working, dining, and placing items, and their user experience directly impacts the travel satisfaction of drivers and passengers.

[0003] Currently, there are three main types of in-vehicle tray tables: First, those fixed to the back of the front seats, unfolding and folding, but their position is entirely dependent on the seat back and cannot be adjusted for different seating postures or usage scenarios (e.g., children using them, adults working). Second, those attached to the armrests (including the center and side armrests), where the fixed position limits angle adjustment to the vertical direction, completely lacking horizontal fore-and-aft adjustment. Third, those integrated into the center console, door panels, or other body components, with their installation position predetermined by the vehicle structure, also lacking X-axis (front-and-back) adjustment. The common drawback of these fixed installation methods is that the tray tables cannot be adjusted for different passenger needs (e.g., the arm reach of passengers of different heights), requiring passengers to consciously adjust their posture to fit the tray table, resulting in poor usability.

[0004] To address the issue of fixed positioning, some automakers have experimented with installing sliding rail structures within vehicles, along with sliding mechanisms to allow for X-axis adjustment of the small table. However, existing sliding mechanisms typically employ relatively complex component combinations to ensure sliding stability. This significantly increases the overall manufacturing cost of the device and makes assembly more difficult. Furthermore, some sliding rail systems require substantial modifications to the vehicle's existing internal structure (such as the seat frame and armrest space), increasing modification costs and potentially impacting the vehicle's interior layout, further limiting their widespread application across various vehicle models.

[0005] In summary, the current in-vehicle tray tables have significant shortcomings in X-axis adjustment. Existing sliding devices for tracks also suffer from high costs, complex structures, and poor adaptability. Therefore, developing a sliding device for tracks that is simple in structure, cost-controllable, more adaptable, and capable of stable X-axis adjustment has become an urgent technical need to be addressed in this field. Utility Model Content

[0006] To address the shortcomings of existing technologies, one of the objectives of this disclosure is to provide a sliding device for tracks that enables stable X-axis adjustment and has a simplified structure.

[0007] This disclosure provides a sliding device for a track, characterized in that it includes: a manually operated component operable to rotate between a locked position and an unlocked position; a rotating component fixedly connected to the manually operated component, the rotation of the manually operated component causing the rotating component to rotate about its axis; a connecting rod component rotatably connected to the rotating component, the rotation of the rotating component driving the connecting rod component to move; and a locking component movably connected to the connecting rod component, the movement of the connecting rod component driving the locking component to rotate; wherein, when the manually operated component is in the locked position, the locking component is in a locked state to restrict the movement of the locking component relative to the track, thereby locking the device on the track; when the manually operated component is in the unlocked position, the locking component is in an unlocked state due to separation from the track, allowing the locking component to move relative to the track.

[0008] When the manual operating component is in the locked position, the sliding device is locked in its current position. When the manual operating component is in the unlocked position, the user can adjust the position of the sliding device on the track as needed, making X-axis adjustments. Furthermore, this transmission mechanism design is more streamlined and has lower manufacturing costs.

[0009] In one embodiment, the locking member is rotatably connected to the connecting rod member.

[0010] In one embodiment, the sliding device further includes: a housing component and a fixed shaft fixedly connected to the housing component; wherein the locking component includes a sleeve portion sleeved on the fixed shaft, and when the manual operation component switches between the locked position and the unlocked position, the sleeve portion rotates around the fixed shaft, thereby realizing the rotation of the locking component.

[0011] In one embodiment, the locking component includes a first locking member, and the linkage component includes a first linkage member, the first end of which is rotatably connected to the rotating component, and the second end of which is rotatably connected to the first locking member. When the manual operation component is in the locked position, the axis of the rotating component, the rotation center of the first end of the first linkage member, and the rotation center of the second end of the first linkage member are collinear or approximately collinear.

[0012] In one embodiment, the manual operating component includes a first latching portion disposed thereon, and the housing component includes a second latching portion disposed thereon, wherein when the manual operating component is in the locked position, the first latching portion engages with the second latching portion.

[0013] In one embodiment, the manual operating component includes a handle, and the housing component includes a recess thereon. When the manual operating component is in the locked position, the handle is accommodated in the recess. When the handle rotates from the locked position to the unlocked position, the manual operating component drives the rotating component to rotate in a first direction. When the handle rotates from the unlocked position to the locked position, the manual operating component drives the rotating component to rotate in a second direction, which is opposite to the first direction.

[0014] In one embodiment, the sliding device further includes: a first elastic element, the first end of which is connected to the housing component and the second end of which is connected to the linkage component, wherein when the handle reaches the unlocked position, the first elastic element applies a pulling force toward the rotating component to the linkage component to restrict the rotating component from rotating in the second direction, thereby keeping the handle in the unlocked position.

[0015] In one embodiment, the sliding device further includes a second elastic element, the first end of which is connected to the housing component and the second end of which is connected to the locking component. In one embodiment, the first connecting rod includes: a first connecting portion including a first hole structure disposed thereon; a second connecting portion including a second hole structure disposed thereon; and an eccentric shaft including a first shaft segment and a second shaft segment fixedly connected thereto, wherein the axis of the first shaft segment and the axis of the second shaft segment are eccentrically offset; the eccentric shaft further includes an adjustable hole disposed thereon, wherein the first hole structure is sleeved on the first shaft segment, the second hole structure is sleeved on the second shaft segment, and the eccentric shaft is rotated by rotating the adjustable hole, thereby adjusting the relative position of the first connecting portion and the second connecting portion.

[0016] In one embodiment, the effective length of the first connecting rod is changed by altering the relative positions of the first connecting portion and the second connecting portion, thereby driving the locking component to rotate around the fixed axis to adapt to different tracks.

[0017] In one embodiment, the sliding device further includes a third elastic element, the first end of which is connected to the connecting rod component and the second end of which is connected to the locking component.

[0018] In one embodiment, the housing component further includes a protrusion thereon that extends downward and is capable of being inserted into and sliding within the track. Attached Figure Description

In this specification, the same or similar reference numerals indicate the same or similar components. The following description of the embodiments of this disclosure with reference to the accompanying drawings is intended to explain the overall inventive concept of this disclosure and should not be construed as a limitation thereof.

[0037] The terms “comprising,” “including,” and similar terms as used in this disclosure should be understood as open-ended terms, meaning “including / including but not limited to,” implying that other content may also be included. The term “based on” means “at least partially based on.” The term “one embodiment” means “at least one embodiment”; the term “another embodiment” means “at least one additional embodiment,” and so on.

[0038] This application proposes a sliding device 10 for a track. Figure 1 A schematic diagram illustrating an application scenario of the sliding device 10 is shown. The device 10 can be installed on a track 20 inside the vehicle and can slide and lock into position on the track 20. The sliding device 10 can accommodate a support rod 30, which is connected to a small table 40 located above it. When a user inside the vehicle wants to adjust the position of the small table 40, they can unlock the sliding device 10, move it to the desired position on the track 20, and finally lock it in that position. The track 20 used by the sliding device 10 can be an existing track inside the vehicle, such as a seat track provided for a movable seat 50, or a track specifically designed for the device 10.

[0039] The first embodiment is as follows.

[0040] Figure 2 An external structural diagram of a sliding device 10 according to a first embodiment of the present disclosure is shown. It can be seen that the device 10 includes a manually operated component 11, which can be manually operated by a user to place it in a locked position or an unlocked position. Specifically, when the user pulls the manually operated component 11 upwards... Figure 2 As shown, the manual operating component 11 is in the unlocked position, at which time the sliding device 10 can slide on the track 20. When the user presses the manual operating component 11 down into the groove 184 on the housing of the device 10, the manual operating component 11 is in the locked position, at which time the sliding device 10 is locked and can no longer move.

[0041] Figure 3 An exploded internal view of the sliding device 10 according to a first embodiment of the present disclosure is shown. Figure 4 An assembly diagram of the main components of the sliding device 10 according to a first embodiment of the present disclosure is shown. (See reference...) Figure 3 and Figure 4 The sliding device 10 includes a manual operating component 11, a rotating component 12, a connecting rod component 13, and a locking component 14. As previously described, the manual operating component 11 is operably rotatable between a locked position and an unlocked position. The rotating component 12 is fixedly connected to the manual operating component 11, and the rotation of the manual operating component 11 causes the rotating component 12 to rotate about its axis l. The rotating component 12 may be a cylindrical shaft. The connecting rod component 13 is rotatably connected to the rotating component 12, and the rotation of the rotating component 12 drives the connecting rod component 13 to move. The locking component 14 is movably connected to the connecting rod component 13, and the movement of the connecting rod component 13 drives the locking component 14 to rotate.

[0042] Figure 5 This diagram shows the internal state of the device 10 when the manual operating component 11 is in the locked position. Figure 6 A diagram showing the internal state of the device 10 when the manual operating component 11 is in the unlocked position is illustrated. (Reference) Figure 5 When the manual operating component 11 is in the locked position, the locking component 14 is locked, restricting its movement relative to the track 20, thereby locking the device 10 onto the track 20. At this time, the sliding device 10 is locked in its current position. (Reference) Figure 6 When the manual operating component 11 is in the unlocked position, the locking component 14 is unlocked due to its separation from the track 20, allowing the locking component 14 to move relative to the track 20. At this time, the user can adjust the position of the sliding device 10 on the track 20 as needed. Furthermore, the user can also detach the sliding device 10 from the track 20, completely removing it from the track 20. In this embodiment, by controlling the manual operating component 11 to rotate the rotating component 12, the connecting rod component 13 is displaced, thereby correspondingly changing the rotation angle of the locking component 14. This transmission mechanism design is more streamlined and has lower manufacturing costs.

[0043] refer to Figure 4The main body of the connecting rod component 13 is a rod-shaped or flat structure of a certain length. The connecting rod component 13 is rotatably connected to the locking component 14. Figure 7 It shows Figure 4 A schematic diagram of the component assembly located in area A. Figure 8 An exploded view of the components located in area A is shown, including locking component 14, hinge shaft 15, fixing shaft 16, and flange fastener 17. Locking component 14 includes a first sleeve portion 141 and a second sleeve portion 142 disposed on its body, wherein the first sleeve portion 141 is fitted onto hinge shaft 15. (Continue referring to...) Figure 4 One end of the connecting rod component 13 is also sleeved on the hinge shaft 15, and the locking component 14 is connected to the connecting rod component 13 by a hinge. This hinge connection allows the movement of the connecting rod component 13 to be transmitted to the locking component 14, and the locking component 14 can only move within a specific range. It is easy to understand that the connecting rod component 13 and the locking component 14 may also be connected by other movable connection methods.

[0044] Continue to refer to Figure 8 The second sleeve portion 142 of the locking component 14 is sleeved on the fixed shaft 16. (See reference) Figure 3 The sliding device 10 also includes a housing component 18, which can be specifically divided into an upper housing 181 and a lower housing 182. Figure 3 An outer view of the upper housing 181 is shown. Figure 9 A further internal view of the upper housing 181 is shown. It can be seen that the inner side of the upper housing 181 has multiple holes for receiving a flange, fastener 17, the first elastic element 19 described below, and the second elastic elements 20a and 20b described below. Return Figure 7 The fixed shaft 16 is fixedly connected to the housing component 18, for example, by means of a flange and fasteners 17, and is fixed to the upper housing 181. Since the fixed shaft 16 is stationary within the device 10, when the manual operating component 11 switches between the locked and unlocked positions, the second sleeve portion 142 rotates about the fixed shaft 16, thereby rotating the locking component 14. The locking component 14 includes a locking hook portion 143 located at its bottom. The movement of the connecting rod component 13 is transmitted to the locking component 14 via the hinge shaft 15, causing the locking component 14 to rotate about the fixed shaft 16. Accordingly, the locking hook portion 143 can move to abut against the track 20 to be in a locked state (e.g., Figure 5 As shown), it can also be moved to separate from track 20 to be in the unlocked state (as shown). Figure 6 (As shown).

[0045] In another embodiment, the locking member 14 may be fixedly connected to the shaft 16 or integrally formed (not shown). The housing member 18 of the device 10 has two opposing fixing holes (not shown) that receive the two ends of the shaft 16 respectively. Since the fixing holes are fixed within the device, when the manual operating member 11 switches between the locked position and the unlocked position, the second sleeve portion 142 and the shaft 16 rotate about an axis passing through the center of the two holes, thereby achieving the rotation of the locking member 14.

[0046] refer to Figure 4 In this embodiment, the locking component 14 includes a first locking member 14a and a second locking member 14b. The connecting rod component 13 includes a first connecting rod 13a and a second connecting rod 13b, with the second connecting rod 13b distributed opposite to the first connecting rod 13a. The first end 130a of the first connecting rod 13a is rotatably connected to the rotating component 12, and its second end 131a is rotatably connected to the first locking member 14a. The first end 130b of the second connecting rod 13b is rotatably connected to the rotating component 12, and its second end 131b is rotatably connected to the second locking member 14b. (Reference) Figure 5 When the manual operating component 11 is in the locked position, the axis l of the rotating component 12, the rotation center of the first end 130a of the first link 13a, and the rotation center of the second end 131a of the first link 13a are collinear or approximately collinear. When these three points are collinear, the transmission mechanism within the sliding device 10 forms a dead point, at which point the transmission angle is zero, the mechanism jams, and it cannot transmit driving force. This locks the rotating component 12, preventing it from moving the first link 13a and the first locking member 14a. Similarly, simultaneously, the axis l of the rotating component 12, the rotation center of the first end 130b of the second link 13b, and the rotation center of the second end 131a of the second link 13b are collinear or approximately collinear (not shown). At this time, the rotating component 12 also cannot move the second link 13b and the second locking member 14b. This dead point state can be released by external force intervention, such as when the user moves the manual operating component 11 to the unlocked position.

[0047] Optionally, to improve the locking effect, such as Figure 10 As shown, the manual operating component 11 includes a first latching portion 110 disposed thereon, and the housing component 18 includes a second latching portion 183 disposed thereon. When the manual operating component 11 moves from the unlocked position to the locked position, as... Figure 11As shown, the first locking part 110 and the second locking part 183 cooperate to prevent the manual operating part 11 from disengaging from the locked position, and the sliding device 10 can be locked more stably on the track 20. In one example, the first locking part 110 and the second locking part 183 are toothed structures, which mesh with each other when the manual operating part moves to the locked position.

[0048] refer to Figure 2 The manual operating component 11 includes a handle 111, which provides a point of force for the user to push or pull. The housing component 18 includes a recess 184 thereon. When the manual operating component 11 is in the locked position, the handle 111 is received in the recess 184. (Reference) Figure 6 When the handle 111 rotates from the locked position to the unlocked position, the manual operation component 11 drives the rotating component 12 to rotate in the first direction (i.e., counterclockwise as shown in the figure). The counterclockwise rotation of the rotating component 12 drives the first connecting rod 13a located on the left to move to the right. Further, the first connecting rod 13a drives the hinge shaft 15 on the left to move to the right. Under the action of the fixed shaft 16, the locking hook portion 143 of the first locking component 14a rotates clockwise, thereby separating from the track 20 and being in the unlocked state. The transmission mechanism on the right side of the rotating component 12 is very similar to the transmission mechanism on the left side, and its movement process will not be described in detail here.

[0049] refer to Figure 5 When the handle 111 rotates from the unlocked position to the locked position, the manual operating component 11 drives the rotating component 12 to rotate in a second direction (i.e., clockwise as shown in the figure). The second direction is opposite to the first direction. The clockwise rotation of the rotating component 12 drives the first connecting rod 13a located on the left to move to the left. Further, the first connecting rod 13a drives the hinge shaft 15 on the left to move to the left. Under the action of the fixed shaft 16, the locking hook portion 143 of the first locking member 14a rotates counterclockwise, thereby abutting against the track 20 and being in a locked state. The transmission mechanism on the right side of the rotating component 12 is very similar to the transmission mechanism on the left side, and its movement process will not be described in detail here. In addition, it should be noted that in this embodiment, the handle 111 presses down on the locking device 10 and lifts up the unlocking device 10. However, in other embodiments, the manual operating component 11 can be operated in different directions to lock or unlock the device 10. For example, the handle in the manual operating component 11 can move horizontally or vertically to control the sliding device 10.

[0050] Optionally, the sliding device 10 further includes a first elastic element 19. Figure 4A partially enlarged view of the first elastic element 19 is further shown. The first elastic element 19 may be a spring. A first end 191 of the first elastic element 19 is connected to a housing component (e.g., the upper housing 181 described above), and its second end 192 is connected to a connecting rod component (specifically, the first connecting rod 13a). (See reference...) Figure 5 and Figure 6 The first elastic element 19 is in a stretched state, thus exerting a rightward pulling force F on the first connecting rod 13a. When the handle 111 reaches the locked position, refer to Figure 5 The connection point between the first connecting rod 13a and the rotating component 12 (i.e., the first end 130a of the first connecting rod 13a) is slightly higher than the axis l of the rotating component 12. Therefore, the tension applied by the first elastic member 19 forces the connecting rod component (i.e., the first connecting rod 13a) to drive the rotating component 12 to rotate in the second direction (i.e., clockwise), thereby keeping the handle 111 in the unlocked position. Conversely, when the handle 111 reaches the unlocked position, reference... Figure 6 The connection point 130a between the first connecting rod 13a and the rotating component 12 is lower than the axis l of the rotating component 12. Therefore, the tension applied by the first elastic member 19 forces the connecting rod (i.e., the first connecting rod 13a) to drive the rotating component 12 to rotate in the first direction (i.e., counterclockwise). In other words, the first elastic member 19 applies a tension force towards the rotating component 12 to the connecting rod 13a, thereby limiting the rotation of the rotating component 12 in the second direction (i.e., clockwise), thus keeping the handle 111 in the unlocked position. By adding the first elastic member 19 within the sliding device 10, the handle 111 is less likely to disengage from the locked position, increasing the stability of the device 10 in the locked state and preventing the device 10 from sliding on the track 20. Furthermore, after the user pulls the handle 111 up to the unlocked position, the first elastic member 19 helps to hold the handle 111 in that position, making it convenient for the user to adjust its position on the track 20 and preventing the handle 111 from falling into the recess 184 of the housing and causing accidental locking.

[0051] Optionally, the sliding device 10 further includes a second elastic element. Figure 4 A partially enlarged view of the second elastic element is further shown. The second elastic element may be a spring. A first end of the second elastic element is connected to the housing component 18, and its second end is connected to the locking component 14. Specifically, in Figure 4In the device 10, one end 201a of the second elastic member 20a located on the left is connected to the upper housing 181 of the device 10, and the other end 201b is connected to the first locking member 14a. One end of the elastic member 20a hooks onto a hole in the upper housing 181, and the other end hooks onto a hole in the first locking member 14a. This second elastic member can tighten the first locking member 14a, preventing unnecessary collisions between the first locking member 14a and the hinge shaft 15 or fixed shaft 16 during rotation, thus reducing noise. Similarly, one end of the second elastic member 20b located on the right is connected to the upper housing 181 of the device 10, and the other end is connected to the second locking member 14b. This second elastic member 20b can tighten the second locking member 14b, reducing the noise generated by the second locking member 14b during rotation.

[0052] The second embodiment is as follows.

[0053] The second embodiment of this disclosure also proposes a sliding device for a track. Figure 12 An assembly diagram of the main components of a sliding device according to a second embodiment of the present disclosure is shown. The main components of this device are generally similar to those of the first embodiment, except for the first connecting rod 13a. Figure 13 An exploded view of a first connecting member 13a according to a second embodiment of the present disclosure is shown. The first connecting member 13a includes a first connecting portion 136a, a second connecting portion 137a, and an eccentric shaft 138a. The first connecting portion 136a includes a first hole structure 1360a disposed thereon. The second connecting portion 137a includes a second hole structure 1370a disposed thereon. The eccentric shaft 138a includes a first shaft segment 1380a and a second shaft segment 1381a fixedly connected. Figure 14 Further illustrated along Figure 12 The sectional view is shown after the BB plane is cut open. The axis m of the first shaft segment 1380a is eccentric to the axis n of the second shaft segment 1381a. The first hole structure 1360a of the first connecting part 136a is fitted onto the first shaft segment 1380a, and the second hole structure 1370a of the second connecting part 137a is fitted onto the second shaft segment 1381a. Additionally, the device includes a gasket 21, which allows the eccentric shaft 138a to be securely connected to the first connecting part 136a and the second connecting part 137a. Figure 15 It shows Figure 12 The image shows a bottom view of the first connecting member 13a. As can be seen, the eccentric shaft 138a also includes an adjustable hole 1382a disposed thereon. By rotating the adjustable hole 1382a, the eccentric shaft 138a is rotated, thereby adjusting the relative position of the first connecting part 136a and the second connecting part 137a.

[0054] refer to Figure 15The adjustable hole 1382a is marked with graduations 0, 1, 2, 3, etc., and this hole can be an internal hexagonal socket. Adjustment of this hole is typically the responsibility of the manufacturer of the sliding device, and the actual operation is performed by in-house technicians or installers before the equipment leaves the factory. By changing the relative position of the first connecting part 136a and the second connecting part 137a, for example, by using an internal hexagonal wrench to rotate the adjustable hole 1382a from graduation 0 to graduation 3, the effective length of the first connecting rod 13a can be changed. (Reference) Figure 5 The change in length of the first link 13a, transmitted through the hinge shaft 15, drives the locking component 14 to rotate around the fixed shaft 16 to adapt to different tracks 20. Specifically, by adjusting the hole position 1382a, the rotation angle of the locking component 14 (especially the locking hook portion 143) can be adjusted slightly. Figure 16 A detailed schematic diagram of the locking component 14 within the track 20 is shown. The track 20 contains a protrusion 201 for abutting against the locking hook portion 143; however, the height H of the protrusion 201 varies in different tracks 20. The manufacturer's technicians adjust the rotation angle of the locking hook portion 143 according to the specific track on which the sliding device is actually used, so that it abuts against the protrusion 201 in the locked state and separates from the protrusion 201 in the unlocked state. Therefore, the sliding device in the second embodiment has higher adaptability to different tracks 20.

[0055] Optionally, the sliding device also includes a third elastic element 22. Figure 12 A partially enlarged view of the third elastic element 22 is also shown. The third elastic element 22 may be a spring. A first end of the third elastic element 22 is connected to the connecting rod member 13, and a second end is connected to the locking member 14. Specifically, one end of the third elastic element 22 is connected to the first connecting rod member 13a, and the other end is connected to the first locking member 14a. The third elastic element 22 can tighten the first locking member 14a, reducing the clicking noise emitted by the sliding device during locking and unlocking.

[0056] In addition, refer to Figure 16 The housing component 18 of the sliding device also includes a protrusion 185 provided thereon, which extends downward and is capable of inserting into and sliding within the track 20.
