[0017] This application provides a support device 100 for supporting a display panel 200, enabling the display panel 200 to be ejected and retracted. The display panel 200 and the support device 100 combined can be understood as a display device 300. The support device 100 is a device for retractably installing the display panel 200 in the cabin, such as a mechanism within a vehicle central control display device 300, or other mechanisms that require ejecting and retracting the display panel 200. This disclosure does not specifically limit this.

[0018] Reference Figures 1 to 5 The support device 100 includes a base 10, an ejection mechanism 20, a support platform 30, and a first locking mechanism 40.

[0019] The base 10 can be a base for mounting and accommodating various mechanisms. The base 10 and the interior trim of the vehicle 1000 can be separate parts that are fixedly connected, or they can be integrally molded.

[0020] The ejection mechanism 20 is disposed within the base 10. For example, the ejection mechanism 20 may be a scissor mechanism (also known as a double-arm ejection mechanism) or other telescopic mechanism capable of amplifying displacement in a linear direction. The ejection mechanism 20 is connected to the support platform 30 and is configured to accumulate potential energy when the support platform 30 moves in the pressing direction and drive the support platform 30 to reset after release.

[0021] The support platform 30 is connected to the ejection mechanism 20 and has an ejection position and a retracted position. The support platform 30 supports the display panel 200. In use, the display panel 200 is mounted on the support platform 30 and remains relatively fixed to it. The shape of the support platform 30 is adapted to the shape of the display panel 200. Ejection position ( Figure 5 and Figure 7 The support platform 30 drives the display panel 200 to a position outside the base 10 for use, and to a retracted position. Figure 4 and Figure 6 The support platform 30 drives the display panel 200 to retract into the storage position inside the base 10.

[0022] The first locking mechanism 40 is disposed within the base 10 and is configured to lock the support platform 30 when it moves to the retracted position and to release the support platform 30 under the action of an external force.

[0023] In this embodiment, pressing the display panel 200 causes the support platform 30 to move to the retracted position and be locked by the first locking mechanism 40. Pressing again releases the locking mechanism, making the retraction and extension operations simple and reliable, requiring only force applied in the pressing direction. Compared to electric unlocking, this reduces costs.

[0024] In some embodiments, the first locking mechanism 40 may be a conventional push-push switch, or other locking structures that can self-lock after being pressed and release after being pressed again.

[0025] In one example, the first locking mechanism 40 employs a sliding engagement structure of an elastic hook and a limiting groove, specifically including an elastic hook fixed to the support platform 30 and a limiting groove fixed to the base 10. The elastic hook extends downward in a cantilever shape, with a first inclined surface formed on its side near the inner side of the limiting groove, and an outwardly protruding limiting barb at the end of the elastic hook. The limiting groove has an opening to accommodate the sliding insertion of the elastic hook, and a second inclined surface opposite to the first inclined surface is formed on the guide sidewall of the limiting groove. A limiting step is provided at the bottom inner side of the limiting groove. When the support platform 30 drives the elastic hook to insert into the limiting groove in the pressing direction, the first inclined surface of the elastic hook abuts against the second inclined surface of the limiting groove. Under the action of the normal component force of the inclined surface, the elastic hook is forced to undergo elastic deformation and shift away from the limiting step. When the elastic hook continues to move downward and crosses the limit step, the elastic hook is released from force and resets on its own elasticity, causing the limit hook to hang below the limit step, thereby preventing the bearing platform 30 from resetting upward and achieving locking.

[0026] When the support platform 30 is pressed again, the elastic hook is pressed down further in the pressing direction, and the lower side of the limiting hook or the side wall of the elastic hook comes into contact with the guide slope at the bottom of the limiting slide groove again, forcing the elastic hook to deflect elastically again and disengage from the limiting step; at this time, the support platform 30 moves upward under the thrust of the ejection mechanism 20, and the elastic hook slides out of the limiting slide groove in the opposite direction along the second slope, thus unlocking.

[0027] In some embodiments, the first locking mechanism 40 is configured to release the support platform 30 when it continues to move in the pressing direction from its retracted position. With this configuration, the user can lock and release the support platform 30 by pressing the display panel 200 twice consecutively in the same pressing mode, moving it in the pressing direction without switching operating directions, further reducing the difficulty of operation.

[0028] With the above settings, there is no need to set up other components to trigger the first locking mechanism 40 to unlock, thus simplifying the number of components.

[0029] In some embodiments, the ejection mechanism 20 is a scissor mechanism. The scissor mechanism has a small retraction envelope and can stably extend and retract within the base 10 in the pressing direction, so that the support platform 30 moves smoothly and is not prone to swaying during ejection and retraction.

[0030] For example, refer to Figure 2 , Figures 4 to 7 The ejection mechanism 20 includes a first fork arm 21 and a second fork arm 22. The first fork arm 21 and the second fork arm 22 are mounted on the base 10 via a second mounting shaft 24. The first fork arm 21 and the second fork arm 22 are hinged together in an X-shaped linkage via the second mounting shaft 24. The first fork arm 21 and the second fork arm 22 are also connected by a reset member 23. During the pressing process, the reset member 23 accumulates potential energy and tends to drive the first fork arm 21 and the second fork arm 22 to reset. After the support platform 30 is reset, the reset member 23 will drive the first fork arm 21 and the second fork arm 22 to reset. The reset member 23 can be a torsion spring.

[0031] The support platform 30 is provided with a first slide groove 31 and a second slide groove 32 on the side facing the ejection mechanism 20. The top of the first fork arm 21 cooperates with the first slide groove 31 through a slider, and the top of the second fork arm 22 cooperates with the second slide groove 32 through a slider.

[0032] The first locking mechanism 40 provided in this application embodiment can directly lock the carrier platform 30, or indirectly lock the carrier platform 30 through the display panel 200 disposed on the carrier platform 30.

[0033] The display panel 200 is typically detachably connected to the support platform 30 so that the display panel 200 can be maintained or used independently.

[0034] To improve the stability of the support platform 30 in the retracted position, in some embodiments, multiple first locking mechanisms 40 are provided, spaced apart. For example, two first locking mechanisms 40 lock the sides of the support platform 30 respectively, while one first locking mechanism 40 locks the middle of the support platform 30.

[0035] In some embodiments, to prevent the force of the first locking mechanism 40 from affecting the display panel 200, the first locking mechanism 40 directly locks the support platform 30. In order to reduce the stability of the display panel 200 during use, in other embodiments, the display panel 200 can be locked separately by the second locking mechanism 50.

[0036] For example, the two sides of the display panel 200 are locked by two second locking mechanisms 50 respectively.

[0037] In some embodiments, the support device 100 further includes a second locking mechanism 50. The second locking mechanism 50 is configured to lock the display panel 200 when it moves to the retracted position along with the support platform 30, and to release the display panel 200 when it moves away from the retracted position toward the ejected position along with the support platform 30. This configuration ensures that the display panel 200 is locked by the second locking mechanism 50 while the support platform 30 is retracted, keeping the display panel 200 fixed in its retracted state and preventing loosening. When the display panel 200 needs to be disassembled for use or maintenance, the second locking mechanism 50 releases the display panel 200 during the ejection process of the support platform 30, facilitating disassembly and assembly.

[0038] In some embodiments, refer to Figures 4 to 10 The second locking mechanism 50 includes a bracket 51, a guide rod 52, and a locking element 53.

[0039] A bracket 51 is disposed on the base 10. Exemplarily, the bracket 51 may be a fixed bracket 51. A guide rod 52 is disposed on the bracket 51 and configured to limit the movement trajectory of the locking member 53. The locking member 53 is rotatably disposed on the support platform 30, and the guide rod 52 is configured to guide the rotation of the locking member 53 to lock or release the display panel 200.

[0040] For example, a fixing block 57 is provided on the side of the support platform 30 facing the ejection mechanism 20, and a locking member 53 is disposed on the fixing block 57 via a first mounting shaft 58. When the display panel 200 is pressed, it drives the support platform 30 to move in the pressing direction, thereby driving the locking member 53 to move in the pressing direction. Under the restriction of the guide rod 52, the locking member 53 moves in the pressing direction while causing the first mounting shaft 58 to rotate in the forward direction until the display panel 200 is locked. At this time, the first locking mechanism 40 locks the support platform 30. After the first locking mechanism 40 releases the support platform 30, the ejection mechanism 20 pushes the support platform 30 from the retracted position to the ejected position, and drives the display panel 200, thereby driving the locking member 53 to move in the opposite direction of the pressing direction. Under the restriction of the guide rod 52, the locking member 53 will rotate in the reverse direction, releasing the display panel 200. In this embodiment, the first locking mechanism 40 releases the support platform 30 first, and the second locking mechanism 50 releases the display panel 200 afterwards.

[0041] With the above settings, the locking member 53 rotates around a predetermined trajectory under the constraint of the guide rod 52, which can accurately lock or release the display panel 200, and the locking position is stable and has good repeatability.

[0042] In some embodiments, the locking member 53 has a locking portion 531 and a guide portion 532. The locking portion 531 is configured to lock the first engaging portion 310 of the display panel 200 when the display panel 200 moves to the retracted position, and to release the first engaging portion 310 when the display panel 200 leaves the retracted position; the guide portion 532 is configured to cooperate with the guide rod 52 to guide the locking member 53 to rotate, such that the locking portion 531 locks or releases the first engaging portion 310. Exemplarily, the locking portion 531 may be a first surface of the locking member 53, and the guide portion 532 may be a second surface of the locking member 53, or may be other parts capable of separately performing the locking and guiding functions. With this configuration, locking and guiding are performed separately by different parts of the same locking member 53, resulting in a compact structure and coordinated operation.

[0043] For example, the first mating part 310 is a slot, and the locking part 531 has a protrusion. In the locked state, the protrusion is engaged in the slot. After the first locking mechanism 40 releases the support platform 30, the support platform 30 is pushed upward by the ejection mechanism 20, causing the locking member 53 to rotate and the locking part 531 to exit the slot, thereby releasing the display panel 200.

[0044] In the embodiments of this application, the locking member 53 can rotate naturally without the need for components such as torsion springs, thereby stably locking or releasing the display panel 200, which helps to extend the service life of the support device 100.

[0045] Since the position of the locking member 53 moves along the pressing direction and the opposite direction, and the locking member 53 itself also rotates, the movement trajectory of the guide portion 532 of the locking member 53 is irregular.

[0046] To ensure the locking member 53 engages with the guide rod 52, in some embodiments, the guide rod 52 is fixed to the bracket 51, and the guide portion 532 includes a first guide surface 5321 and a second guide surface 5322 connected together. The first guide surface 5321 is positioned close to the first mounting shaft 58, and an obtuse angle is formed between the first guide surface 5321 and the second guide surface 5322. During the forward rotation of the locking member 53 to lock the display panel 200, the second guide surface 5322 engages with the guide rod 52 first, and then the first guide surface 5321 engages with the guide rod 52 until the locking portion 531 of the locking member 53 locks the display panel 200. During the reverse rotation of the locking member 53 to release the display panel 200, the first guide surface 5321 engages with the guide rod 52 first, and then the second guide surface 5322 engages with the guide rod 52. It can be understood that the guide portion 532 needs the first guide surface 5321 and the second guide surface 5322 to alternately engage with the guide rod 52 to guide the rotation of the locking member 53.

[0047] In some technical solutions, a charging interface is provided at the contact position between the locking part 531 and the display panel 200 to realize the in-situ charging function of the display panel 200.

[0048] Although the arrangement of the first guide surface 5321 and the second guide surface 5322 can satisfy the requirement of rotating the locking member 53 to lock or release the display panel 200, during the process of the user pressing the display panel 200 and driving the support platform 30 to continue moving from the retracted position along the pressing direction to unlock the first locking mechanism 40, due to the lack of restraint, the locking member 53 will rotate slightly in the positive direction, causing the locking part 531 to squeeze the charging interface near the first mating part 310, which has an adverse effect on the charging function.

[0049] When the user presses the display panel 200, the support platform 30 moves from its retracted position along the pressing direction, causing the first locking mechanism 40 to unlock. This design can be understood as a press-free stroke, used to unlock the first locking mechanism 40. The pressing-free stroke occurs when the locking part 531 rotates forward and presses against the charging interface near the first mating part 310. In one example, the charging interface uses a multi-pin design.

[0050] To reduce the pressure exerted by the locking part 531 on the charging interface, in some embodiments, refer to Figures 11 to 14The locking member 53 has a locking part 531 and a guide groove 533. The second locking mechanism 50 also includes a first connecting rod 54, a second connecting rod 55, and an elastic member 56. The first connecting rod 54 and the second connecting rod 55 are rotatably mounted on the bracket 51. One end of the guide rod 52 is connected to the first connecting rod 54, and the other end is connected to the second connecting rod 55. One end of the elastic member 56 is connected to the guide rod 52, and the other end is connected to the base 10. The guide rod 52 is confined within the guide groove 533. The guide groove 533 cooperates with the guide rod 52 to restrict the rotation of the locking member 53 when the display panel 200 continues to move in the pressing direction along the retracted position following the support platform 30.

[0051] For example, the elastic element 56 may be a spring or other elastic body for providing a return preload force after the locking element 53 has rotated. Alternatively, a linkage may engage with the elastic element 56 to limit rotation of the locking element 53.

[0052] In this embodiment, the first link 54 and the second link 55 can swing relative to the bracket 51, so that the guide rod 52 can remain in the guide groove 533 during the downward free stroke phase, thereby restricting the rotation of the locking member 53. During the downward free stroke phase, the locking member 53 moves along the pressing direction without rotation. After the pressing force is removed, the guide groove 533 of the locking member 53 will generate an irregular movement trajectory, and the guide rod 52 can have an arc movement trajectory under the action of the elastic member 56, the first link 54 and the second link 55, thereby adapting to the position of the guide groove 533, so that when the support platform 30 switches between the retracted position and the ejected position, it does not hinder the rotation of the locking member 53.

[0053] When the bearing platform 30 is in the retracted position, the elastic element 56 is in a pre-stretched state. During the downward free stroke, the locking element 53 moves along the pressing direction but does not rotate. During the process of the bearing platform 30 moving from the retracted position to the ejected position, the elastic element 56 accumulates elastic force. The ejection force of the ejection mechanism 20 can overcome the elastic force of the elastic element 56 and eject the bearing platform 30.

[0054] In some embodiments, the support device 100 further includes a damping structure 60 connected between the base 10 and the support platform 30, configured to provide resistance to movement when the support platform 30 moves. Exemplarily, the damping structure 60 may be a damping component (e.g., a damper with gear and rack engagement), or other structures capable of providing damping force when the support platform 30 moves. With this configuration, the support platform 30 experiences resistance from the damping structure 60 during ejection and retraction, resulting in smooth, shock-free movement and improved user experience.

[0055] This application exemplarily describes the working process of the support device 100: When the support platform 30 is in the extended position, pressing the display panel 200 causes the ejection mechanism 20 to accumulate potential energy, and the support platform 30 moves to the retracted position. The first locking mechanism 40 locks the support platform 30, while the second locking mechanism 50 locks the display panel 200. Pressing the display panel 200 again in the pressing direction causes the first locking mechanism 40 to release the support platform 30, followed by the second locking mechanism 50 releasing the display panel 200. The ejection mechanism 20 then drives the support platform 30 to reset to the extended position. Through the above process, the extension, retraction, and locking of the display panel 200 can be completed simply by applying force in the pressing direction.

[0056] According to a second aspect of this application, embodiments of this application also provide a display device 300, including a support device 100 and a display panel 200 provided in embodiments of this application. The display panel 200 is disposed on a support platform 30 and detachably connected to the support platform 30. Since the display device 300 includes the support device 100 provided in embodiments of this application, it has all the beneficial effects of the support device 100, which will not be elaborated here.

[0057] In some embodiments, the display panel 200 is provided with a first mating portion 310, which is configured to engage with the locking portion 531 of the locking member 53 of the second locking mechanism 50 of the support device 100. Exemplarily, the first mating portion 310 may be a groove on the side of the display panel 200, or it may be a structure such as a buckle or a boss that can engage with the locking member 53. This disclosure does not specifically limit it in this way.
