Display turnover device

Abstract

A display turnover device comprises a rail assembly, a sliding block assembly and a connecting rod assembly. The rail assembly comprises a rail and a first guide groove, and the first guide groove comprises a first longitudinal section, a second longitudinal section and a first slope section communicating the first longitudinal section with the second longitudinal section, the sliding block assembly is arranged in the rail and provided with a second guide groove, and the second guide groove comprises a third longitudinal section. The connecting rod assembly comprises a first connecting rod and a second connecting rod, the first connecting rod comprises a pivot shaft pivoted to the sliding block assembly, and the second connecting rod is hinged to the first connecting rod and comprises an actuating pin penetrating through the first guide groove and the second guide groove. When the sliding block assembly moves from the first longitudinal section to the second longitudinal section along the track, the actuating pin is limited by the intersection of the third longitudinal section and the first slope section to be positioned. The pivotal shaft continuously moves along with the sliding block assembly, so that the pivotal shaft and the actuating pin are relatively close to each other, and the second connecting rod is driven to rotate towards a first direction by taking the actuating pin as the center until the connecting rod assembly is in a folded state. Therefore, the display can be translated and overturned, and the configuration of power components is reduced.

Description

Technical Field

[0001] The present invention relates to a display flipping device, in particular to a display flipping device having a track, a slider and a connecting rod arranged on a slider assembly. Background Art

[0002] Most vehicles today are equipped with multimedia devices featuring displays that provide multimedia services to passengers. Some high-end vehicles even feature larger displays. To avoid large displays taking up space and obstructing passenger movement and vision, these displays are typically retractable.

[0003] A common folding mechanism uses a motor to tilt the display, allowing it to flip upward and be stored flat beneath the vehicle's roof when not in use; when in use, it flips downward and stands upright. This configuration allows the display to be positioned specifically to accommodate passengers' limited field of view. To enable the display to be moved relative to the passenger for optimal viewing distance, it requires additional tracks and a drive mechanism. This requires multiple power components (e.g., motors) to separately drive the display's translation and flipping movements. Summary of the Invention

[0004] The present invention provides a display flipping device, wherein the track assembly and the slider assembly respectively have guide grooves. When the slider assembly moves in the track assembly, the guide grooves cooperate with each other to drive the connecting rod assembly arranged on the slider assembly to open and close.

[0005] The present invention provides a display flipping device, comprising a track assembly, a slider assembly, and a connecting rod assembly. The track assembly comprises a track and a first guide groove corresponding to the track, the first guide groove comprising a first longitudinal section and a second longitudinal section parallel to each other, and a first sloped section connecting the first longitudinal section and the second longitudinal section. The slider assembly is disposed in the track and is provided with a second guide groove. The connecting rod assembly comprises a first connecting rod and a second connecting rod, the first connecting rod comprising a pivot shaft pivotally connected to the slider assembly, the second connecting rod being hinged to the first connecting rod, and the second connecting rod comprising an actuating pin extending through the first and second guide grooves. When the slider assembly moves along the track from the first longitudinal section to the second longitudinal section, the actuating pin is positioned at the intersection of the second guide groove and the first sloped section. The pivot shaft continuously moves with the slider assembly, causing the pivot shaft and the actuating pin to approach each other and driving the second connecting rod to rotate in a first direction about the actuating pin until the connecting rod assembly is in a folded state.

[0006] In one embodiment of the present invention, the second guide groove includes a second slope section. When the actuating pin is restricted by the intersection of the first longitudinal section and the second slope section, the actuating pin does not move with the slider assembly when the slider assembly moves.

[0007] In one embodiment of the present invention, the second guide groove includes a third longitudinal section. When the slider assembly moves along the track from the first longitudinal section to the second longitudinal section, the actuating pin is positioned by the intersection of the third longitudinal section and the first slope section.

[0008] In one embodiment of the present invention, the second guide groove includes a third slope section, which extends from one end of the third longitudinal section. When the slider assembly moves in the track corresponding to the second longitudinal section, the actuating pin is restricted by the intersection of the second longitudinal section and the third slope section and is positioned on the slider assembly. The slider assembly drives the actuating pin to move along the second longitudinal section.

[0009] In one embodiment of the present invention, the second guide groove includes a second slope section and a third slope section, the second slope section and the third slope section respectively extend from the two ends of the third longitudinal section, and the second slope section and the third slope section respectively deviate to the two sides of the third longitudinal section, and when the slider assembly moves in the track, the second slope section can move to where it partially overlaps with the first longitudinal section, and the third slope section can move to where it partially overlaps with the second longitudinal section.

[0010] In one embodiment of the present invention, the second guide groove includes a second slope section, which extends from a front end of the third longitudinal section. The second slope section partially overlaps with the first longitudinal section. When the slider assembly moves in the track corresponding to the first longitudinal section, the second slope section cooperates with the first longitudinal section to enable the connecting rod assembly to maintain an expanded state and move along the first longitudinal section.

[0011] In one embodiment of the present invention, the second guide groove includes a third slope section, which extends from a rear end of the third longitudinal section. The third slope section partially overlaps with the second longitudinal section. When the slider assembly moves in the track corresponding to the second longitudinal section, the second longitudinal section cooperates with the third slope section to maintain the connecting rod assembly in a folded state and move along the second longitudinal section with the slider assembly.

[0012] In one embodiment of the present invention, the first longitudinal segment, the second longitudinal segment and the third longitudinal segment are arranged in an upward and downward offset relationship. From top to bottom, the first longitudinal segment is arranged in a first plane, the third longitudinal segment is arranged in a second plane, and the second longitudinal segment is arranged in a third plane.

[0013] In one embodiment of the present invention, when the connecting rod assembly moves along the first longitudinal section, the actuating pin is located in the first plane.

[0014] In one embodiment of the present invention, when the connecting rod assembly moves from the first longitudinal section to the second longitudinal section, the actuating pin remains in the second plane.

[0015] In one embodiment of the present invention, when the connecting rod assembly is in the folded state and moves along the second longitudinal section, the actuating pin is located in the third plane.

[0016] In one embodiment of the present invention, the second connecting rod is hinged to the first connecting rod via a hinge shaft.

[0017] In one embodiment of the present invention, when the connecting rod assembly is in the folded state, the first connecting rod and the second connecting rod are folded along the hinge axis.

[0018] In one embodiment of the present invention, when the first link and the second link are substantially horizontally disposed, the link assembly is defined as being in an unfolded state.

[0019] In one embodiment of the present invention, a display is disposed on the first connecting rod, and the first connecting rod can drive the display to flip. When the connecting rod assembly is in an unfolded state, the display is substantially arranged horizontally.

[0020] In one embodiment of the present invention, a display is provided on the first connecting rod, and the first connecting rod can drive the display to flip. When the connecting rod assembly is in a folded state, the display is upright.

[0021] In one embodiment of the present invention, the slider assembly includes a first slider and a second slider, the second guide groove is set in the first slider and the pivot shaft is pivotally connected to the second slider, the second slider is buckled with the first slider and linked to the first slider, when the actuating pin is located in the second longitudinal section, the first slider can be disengaged from the second slider.

[0022] In one embodiment of the present invention, a clearance groove is provided in the track corresponding to the second longitudinal section, and the second slider is hooked with the first slider by a spring arm hook. When the spring arm hook passes through the clearance groove, the spring arm hook is engaged with the clearance groove and disengages from the second slider, thereby fixing the second slider.

[0023] In one embodiment of the present invention, after the first slider is disengaged from the second slider, the first slider continues to move along the second longitudinal section away from the second slider, driving the actuating pin away from the pivot axis and further driving the second connecting rod to rotate in a second direction (D2).

[0024] In one embodiment of the present invention, the track assembly includes a wire groove, one side of the wire groove is connected to one side of the track, a driving cable is passed through the wire groove, and the slider assembly is connected to the driving cable.

[0025] In one embodiment of the present invention, the track assembly includes a long body and at least one accessory block. The first longitudinal section is formed in the long body, and the long body is provided with a slot connected to the first longitudinal section. The at least one accessory block is arranged in the slot to form a second longitudinal section and a first slope section.

[0026] The display flipping device of the present invention utilizes a first guide groove on a track assembly to cooperate with a second guide groove on a slider assembly to enable the slider assembly to move on the track assembly, thereby pushing the connecting rod assembly and driving the actuating pin of the connecting rod assembly to open and close the connecting rod assembly, thereby enabling the display to be translated and flipped.

[0071] See Figures 1 to 4One embodiment of the present invention provides a display flipping device that is mounted on a vehicle roof structure 10. The roof structure 10 shown in the figure is a sunroof frame, but the roof structure 10 may also be other components of the vehicle roof. In the simplest embodiment, the display flipping device of the present invention includes at least a track assembly 100, a slider assembly 200, and a connecting rod assembly 300, wherein the connecting rod assembly 300 is used to connect to a display 400 and is capable of moving and flipping the display 400. In this embodiment, the track assembly 100, slider assembly 200, and connecting rod assembly 300 are disposed on opposite sides of the display 400 to balance the movement and flipping motion. The structures of the track assembly 100, slider assembly 200, and connecting rod assembly 300 are symmetrical, and the following description will only use the structure of one side as a representative example.

[0072] See Figures 3 and 4 The track assembly 100 includes a track 110 and a first guide slot 101. The first guide slot 101 is arranged corresponding to the track 110. Specifically, the first guide slot 101 is longitudinally parallel to the track 110. In this embodiment, the first guide slot 101 includes a first longitudinal section 121, a first sloped section 122, and a second longitudinal section 123. The first longitudinal section 121 and the second longitudinal section 123 are arranged parallel to each other. The first sloped section 122 is arranged between the first longitudinal section 121 and the second longitudinal section 123 and connects the first longitudinal section 121 and the second longitudinal section 123. In this embodiment, the track assembly 100 includes a body 111 and at least one accessory block 120. The body 111 is elongated, and the first longitudinal section 121 is formed within the elongated body 111. The main body 111 is provided with a notch 112 that connects to a first longitudinal section 121. The accessory block 120 is positioned within the notch 112, forming a first sloped section 122 and a second longitudinal section 123. This subassembly structure allows the main body 111 to be manufactured via extrusion, while the accessory block 120 can be manufactured via plastic injection molding. This eliminates the need for expensive metalworking processes (such as casting, machining, or sheet metal processing), reducing processing costs. In other preferred embodiments, the track assembly 100 can be integrated with a track on a vehicle sunroof.

[0073] See Figures 3 and 4 In this embodiment, the track assembly 100 further includes a wire groove 130 , which is longitudinally parallel to the track 110 , and one side of the wire groove 130 is connected to one side of the track 110 . A drive cable 131 is also passed through the wire groove 130 .

[0074] See Figures 3 and 4The slider assembly 200 is disposed in the track 110 and is connected to the drive cable 131. Thus, the slider assembly 200 can be driven by the drive cable 131 to translate axially along the track 110. A second guide groove 202 is provided on the slider assembly 200. The second guide groove 202 includes a third longitudinal section 211, a second sloped section 212, and a third sloped section 213. The second sloped section 212 and the third sloped section 213 extend from both ends of the third longitudinal section 211, respectively, and are biased toward either side of the third longitudinal section 211. Specifically, the second sloped section 212 extends upward from a front end of the third longitudinal section 211, while the third sloped section 213 extends downward from a rear end of the third longitudinal section 211.

[0075] See Figures 3 and 4 The connecting rod assembly 300 includes a first connecting rod 310 and a second connecting rod 320. The first connecting rod 310 includes a pivot shaft 311 and is pivotally connected to the slider assembly 200. The second connecting rod 320 is hinged to the first connecting rod 310. The second connecting rod 320 is hinged to the first connecting rod 310 via a hinge shaft 321. The second connecting rod 320 includes an actuating pin 322, which is inserted into the first guide slot 101 and the second guide slot 202.

[0076] See Figure 1 The first link 310 and the second link 320 can rotate relative to each other around the hinge shaft 321 to form an expanded state. Specifically, when the link assembly 300 is in the expanded state, the first link 310 and the second link 320 are substantially horizontally arranged.

[0077] See Figure 2 The first link 310 and the second link 320 can rotate relative to each other around the hinge shaft 321 to form a folded state. Specifically, when the link assembly 300 is in the folded state, the first link 310 and the second link 320 are folded along the hinge shaft 321.

[0078] See Figure 1 and Figure 2 , the display 400 is disposed on the first connecting rod 310, and the first connecting rod 310 can drive the display 400 to flip. Figure 1 When the link assembly 300 is in the unfolded state, the display 400 is substantially in a horizontal configuration. Figure 2 When the connecting rod assembly 300 is in the folded state, the display 400 is in an upright position to provide the user with a better viewing angle.

[0079] See Figure 5 and Figure 6The movement stroke of the slider assembly 200 sequentially includes a first section L1, a second section L2, a third section L3, and a fourth section L4. In this embodiment, the leading edge of the slider assembly 200 in the aforementioned movement direction is used as a reference point to illustrate the position of the slider assembly 200 in its movement stroke, and the movement of the slider assembly 200 from the first section L1 to the fourth section L4 is taken as an example for illustration. However, the present invention is not limited thereto. For example, the slider assembly 200 can also move in the opposite direction from the fourth section L4 to the first section L1.

[0080] See Figures 5 to 8 In the first section L1 of the movement stroke of the slider assembly 200 , the slider assembly 200 moves along the first longitudinal section 121 . Figure 7 and Figure 8 It is the junction of the first section L1 and the second section L2. Figures 7 to 10 In the second section L2, the slider assembly 200 moves from the first longitudinal section 121 to the second longitudinal section 123. Figure 11 and Figure 12 In the third section L3, the slider assembly 200 moves along the second longitudinal section 123 to the fourth section L4. Figures 13 and 14 In the fourth section L4, the slider assembly 200 also continues to move along the second longitudinal section 123. In this embodiment, the first longitudinal section 121, the second longitudinal section 123, and the third longitudinal section 211 are arranged with relative vertical offsets. From top to bottom, the first longitudinal section 121 is arranged on a first plane 301, the third longitudinal section 211 is arranged on a second plane 302, and the second longitudinal section 123 is arranged on a third plane 303. However, the present invention is not limited to this arrangement. For example, from bottom to top, the first longitudinal section 121 may be arranged on a first plane 301, the third longitudinal section 211 may be arranged on a second plane 302, and the second longitudinal section 123 may be arranged on a third plane 303. Specifically, the first plane 301, the second plane 302, and the third plane 303 are parallel to each other and substantially parallel to the longitudinal direction of the track assembly 100, that is, the travel range of the slider assembly 200.

[0081] See Figure 5 and Figure 6During the first segment L1 of the slider assembly 200's travel, the slider assembly 200 moves within the track 110 corresponding to the first longitudinal segment 121. Specifically, it moves along the first longitudinal segment 121 of the track 110. At this point, a portion of the second sloped segment 212 overlaps a portion of the first longitudinal segment 121. The actuating pin 322 is constrained by the intersection of the first longitudinal segment 121 and the second sloped segment 212 and lies within the first plane 301. As the slider assembly 200 moves, the actuating pin 322 is pushed by the second sloped segment 212 and moves within the first longitudinal segment 121. Consequently, the actuating pin 322 and the pivot shaft 311 move synchronously with the slider assembly 200. Furthermore, the motion paths of the actuating pin 322, the hinge shaft 321, and the pivot shaft 311 all lie along the first plane 301. The force applied by the slider assembly 200 to the link assembly 300 is along the first plane 301, thereby maintaining the link assembly 300 in the deployed state. Neither the first link 310 nor the second link 320 of the link assembly 300 rotates. As previously described, the second ramp 212 cooperates with the first longitudinal section 121 to maintain the link assembly 300 in the deployed state and allow it to move along the first longitudinal section 121.

[0082] like Figure 7 and Figure 8 As shown, at the intersection of the first section L1 and the second section L2, for the first guide groove 101, the actuating pin 322 moves from the first longitudinal section 121 into the first slope section 122, while for the second guide groove 202, the actuating pin 322 moves from the second slope section 212 into the third longitudinal section 211.

[0083] See Figure 9 and Figure 10 During the second segment L2 of the slider assembly 200's travel, the slider assembly 200 and the connecting rod assembly 300 move from the first longitudinal segment 121 to the second longitudinal segment 123. During this process, a portion of the third longitudinal segment 211 overlaps a portion of the first sloped segment 122. During this movement, the actuating pin 322 is constrained by the intersection of the first sloped segment 122 and the third longitudinal segment 211, maintaining it in the second plane 302. With respect to the second guide slot 202, the actuating pin 322 moves from the second sloped segment 212 along the third longitudinal segment 211 to the third sloped segment 213 until reaching the third segment L3. Specifically, in the second section L2 of the moving stroke of the slider assembly 200, the actuating pin 322 can be pushed by the first slope section 122 and move within the third longitudinal section 211, so that the actuating pin 322 does not move with the slider assembly 200, but the pivot shaft 311 still moves with the slider assembly 200, thereby causing the distance between the actuating pin 322 and the pivot shaft 311 to decrease as the slider assembly 200 moves forward.

[0084] like Figures 9 and 10As shown, in the second section L2 of the travel of the slider assembly 200, the actuating pin 322 is located in the second plane 302, and the movement path of the pivot axis 311 is located in the first plane 301. This allows the first link 310 and the second link 320 of the link assembly 300 to rotate with the relative movement of the actuating pin 322 and the pivot axis 311. As previously described, the first ramp section 122 cooperates with the third longitudinal section 211 to cause the second link 320 of the link assembly 300 to rotate in a first direction D1 about the actuating pin 322. This rotation of the second link 320 causes the hinge axis 321 to revolve around the pivot axis 311 in a direction opposite to the first direction D1, thereby simultaneously causing the first link 310 to rotate in a direction opposite to the first direction D1 about the pivot axis 311 until the link assembly 300 is folded.

[0085] like Figure 11 As shown, at the intersection of the second section L2 and the third section L3 , the actuating pin 322 enters the third slope section 213 for the second guide groove 202 , while the actuating pin 322 enters the second longitudinal section 123 for the first guide groove 101 .

[0086] See Figures 11 to 12 During the third segment L3 of the slider assembly 200's travel, the slider assembly 200 moves within the track 110 corresponding to the second longitudinal segment 123. Specifically, it moves along the second longitudinal segment 123 of the track 110. At this point, a portion of the third sloped segment 213 overlaps a portion of the second longitudinal segment 123, and the actuating pin 322 is constrained by the intersection of the second longitudinal segment 123 and the third sloped segment 213, remaining located in the third plane 303. As the slider assembly 200 moves, the actuating pin 322 is pushed by the third sloped segment 213 and moves within the second longitudinal segment 123. At this point, the actuating pin 322 and the pivot shaft 311 move synchronously with the slider assembly 200. As previously described, the third sloped segment 213 cooperates with the second longitudinal segment 123 to maintain the linkage assembly 300 in its folded state while moving along the second longitudinal segment 123. Therefore, after the display 400 is lowered (placed upright), it maintains its "lowered" position and continues to translate until it reaches its desired position. That is, at this stage, the user can control the display to continue moving to a suitable viewing position (positioning) while maintaining the display angle through manipulation.

[0087] See Figure 3 and Figure 4 In this embodiment, the slider assembly 200 includes a first slider 210 and a second slider 220. The second guide slot 202 is provided in the first slider 210, and the pivot shaft 311 is pivotally connected to the second slider 220. The second slider 220 is engaged with the first slider 210 for interlocking movement. Specifically, the second slider 220 engages the first slider 210 with a spring-loaded hook 221. A clearance slot 113 is provided within the track 110 corresponding to the second longitudinal section 123, which mates with the spring-loaded hook 221.

[0088] See Figures 12 to 14 In the fourth section L4 of the movement stroke of the slider assembly 200, the actuating pin 322 is located in the second longitudinal section 123. When the slider assembly 200 moves, the actuating pin 322 can be pushed by the third slope section 213 and move within the second longitudinal section 123. Figure 12 At the beginning of the fourth section L4, the elastic arm hook 221 passes through the clearance groove 113. The elastic arm hook 221 is engaged with the clearance groove 113 by its elastic force and is simultaneously released from the second slider 220, thereby fixing the second slider 220. Figures 12 to 14 Once the second slider 220 is secured, the first link 310, pivotally connected to the second slider 220 via the pivot axis 311, is fixed and cannot translate, yet it can still rotate. In other words, even when the display 400 is flipped over and positioned upright, it can still rotate. Therefore, even after the display 400 is lowered and positioned, the tilt angle of the display 400 can still be adjusted.

[0089] After the first slider 210 and the second slider 220 are disengaged, the first slider 210 continues to move along the second longitudinal section 123 away from the second slider 220, driving the actuating pin 322 away from the pivot axis 311 and thereby driving the second connecting rod 320 to rotate in a second direction D2. Specifically, the second direction D2 is opposite to the first direction D1.

[0090] The display flip device of the present invention is mounted on the roof structure 10. When the linkage assembly 300 is in the unfolded position, the display 400 can be stored horizontally above a specific seat in the vehicle. When the linkage assembly 300 is actuated to the folded position, the display 400 moves to the side of the seat and assumes an upright position for easier viewing. Furthermore, after the display 400 is flipped to the upright position, its tilt angle can be finely adjusted.

[0091] The display flipping device of the present invention utilizes the first guide slot 101 on the track assembly 100 to cooperate with the second guide slot 202 on the slider assembly 200, enabling the slider assembly 200 to move on the track assembly 100, thereby pushing the connecting rod assembly 300 and simultaneously driving the actuating pin 322 of the connecting rod assembly 300 to engage and disengage the connecting rod assembly 300. The coordinated structures of the track assembly 100 and the slider assembly 200 drive the connecting rod assembly 300 to translate and flip the display 400, thereby reducing the number of power components required.
