In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0045] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0047] In the first aspect, Figures 1 to 4 It shows a display carrier 1000 applied to an embodiment of the present application.

[0048] See also Figure 1The display carrier 1000 includes: two substrates 10; a folding mechanism 15, which is used to connect the two substrates 10 and realize relative folding between the two substrates 10; two sliding shells 11, which are sleeved on the substrates 10 and slidably connected with the substrates 10; a limiting mechanism 12, which includes a mechanism for limiting the relative movement of the sliding shell 11 and the substrate 10, and includes a first engaging member 120 arranged on the substrate 10 and a second engaging member 121 arranged on the sliding shell 11.

[0049] Since the display carrier 1000 of the embodiment of the present application is provided with a sliding shell 11, a substrate 10, a folding mechanism 15 and a limiting mechanism 12, in general, the folding mechanism 15 can drive the two substrates 10 to fold relative to each other, that is, the two substrates 10 can be folded between an unfolded state and a folded state, the sliding shell 11 can slide on the substrate 10, and the relative movement between the sliding shell 11 and the substrate 10 is limited by the structure of the first engaging member 120 and the second engaging member 121. Each substrate 10 is correspondingly sleeved with a sliding shell 11, and each sliding shell 11 can adjust its position relative to the substrate 10, and the position is fixed by the limiting mechanism 12.

[0050] The display carrier 1000 can realize the folding and telescopic functions, realize the adjustment mode of multi-angle and multi-degree-of-freedom adjustment, and increase the movement mode and application scenarios of the display carrier 1000. When the display screen 16 is set on the sliding shell 11, the folding and telescopic functions of the display screen 16 can be realized. Compared with the display module, the display carrier 1000 can increase the visible area of ​​the display screen 16 after folding, and can realize two people's independent split-screen use or game battle after telescopic, which increases the linkage and interactivity of the corresponding display module, and improves operability and playability.

[0051] It should be noted that the structure of the sliding housing 11 of the present application includes but is not limited to a hollow housing having a sleeve and an inner cavity, and the substrate 10 extends from the sleeve into the inner cavity. The substrate 10, on the one hand, supports the sliding housing 11, and on the other hand, limits the sliding housing 11 through the mutual engagement between the first engaging member 120 and the second engaging member 121.

[0052] The display carrier 1000 provided in the embodiment of the present application, based on the above embodiment, further includes a driving mechanism 13 arranged on the substrate 10, the driving mechanism 13 includes a first connecting rod 131 and a pushing component 133, the first connecting rod 131 is pivotally connected to the substrate 10, and the first engaging component 120 is arranged on the first connecting rod 131; the pushing component 133 is used to push the first connecting rod 131 to rotate around the pivot to separate the first engaging component 120 from the second engaging component 121.

[0053] When the sliding shell 11 needs to slide relative to the substrate 10, the first connecting rod 131 is pushed to move in the direction away from the second engaging member 121 by the pushing component 133. The first connecting rod 131 rotates to drive the first engaging member 120 to separate from the second engaging member 121. The sliding shell 11 and the substrate 10 can be separated from the limiting relationship. Manually pushing the sliding shell 11 can achieve movement relative to the substrate 10. Therefore, the assembly operation of the display carrier 1000 is simple and the structural cost is low.

[0054] It should be noted that the first engaging member 120 and the second engaging member 121 are structures that can engage with each other, and the engaging methods include but are not limited to any one of mechanical engaging and electromagnetic engaging, such as Figure 1 , Figure 5 As shown, the present application adopts one of the mechanical snap-fits, the first snap-fit ​​member 120 is selected as a protrusion, and the second snap-fit ​​member 121 is selected as a groove. When the first snap-fit ​​member 120 and the second snap-fit ​​member 121 are engaged, the position of the sliding shell 11 relative to the substrate 10 is fixed. When the first snap-fit ​​member 120 and the second snap-fit ​​member 121 are separated, the sliding shell 11 can slide relative to the substrate 10.

[0055] The shape of the first engaging member 120 includes, but is not limited to, a block, a column, and a sphere.

[0056] The first connecting rod 131 may be pivotally connected to the base plate 10 via a hinge, or may be connected to the base plate 10 in an articulated manner.

[0057] In some embodiments, Figure 5 As shown, the first connecting rod 131 is a strip-shaped rod structure, one end of the first connecting rod 131 is pivotally connected to the base plate 10, and the other end extends in a direction away from the pivot point. The length direction of the first connecting rod 131 and the axis of the base plate 10 or the sliding housing 11 may have a certain angle, so that when the first connecting rod 131 is in a normal stretched state, the first engaging member 120 on the first connecting rod 131 can be in a natural engaging state with the second engaging member 121 on the sliding housing 11, thereby facilitating operation. The extended length of the first connecting rod 131 can be determined according to actual conditions, and is preferably consistent with the length of the base plate 10 in the sliding direction, so that the sliding housing 11 has a larger sliding distance and better stability during the sliding process.

[0058] The display carrier 1000 provided in the embodiment of the present application is based on the above embodiment, and the driving mechanism 13 further includes a second connecting rod 132 connected to the pushing component 133 , and the pushing component 133 drives the first connecting rod 131 to move through the second connecting rod 132 .

[0059] The second connecting rod 132 is used to link the first connecting rod 131. As a preferred embodiment, one end of the second connecting rod 132 is linked to the pushing component 133, and the other end extends to the first engaging member 120 of the first connecting rod 131. In addition, the above embodiment mentioned that the length direction of the first connecting rod 131 is at an angle with the axis of the base plate 10 or the sliding housing 11, so the length direction of the second connecting rod 132 of the embodiment can be parallel to the axis of the base plate 10 or the sliding housing 11, that is, there is an angle between the second connecting rod 132 and the first connecting rod 131. In addition, one end of the first connecting rod 131 is arranged with the first engaging member 120 closer to the second connecting rod 132, so that when the pushing component 133 moves, it drives the second connecting rod 132 to move toward the first connecting rod 131. Since the first connecting rod 131 has a certain length, the end of the added second connecting rod 132 away from the pushing component 133 preferentially contacts the first connecting rod 131 and applies pressure thereto. Since the contact position is located at the end away from the pivot joint of the first connecting rod 131, the pushing component 133 can apply smaller force to achieve a better pushing effect.

[0060] It should be noted that the first connecting rod 131 and the second connecting rod 132 may be rigid rods, and the materials used include but are not limited to metal and plastic.

[0061] The display carrier 1000 provided in the embodiment of the present application further includes a reset mechanism 14, which is disposed between the substrate 10 and the first connecting rod 131 and is used to drive the first engaging member 120 and the second engaging member 121 to engage with each other under the action of elastic force.

[0062] The reset mechanism 14 is used to automatically reset the first engaging member 120 on the first connecting rod 131 after the pushing component 133 pushes the first connecting rod 131 to separate the first engaging member 120 from the second engaging member 121. According to the functionality of the reset mechanism 14, the reset mechanism 14 can select any one of a spring resetter, an elastic body, and an electric resetter. In this embodiment, an elastic body that is simple to assemble and more cost-effective is selected as the reset mechanism 14. Figure 5 As shown, the reset mechanism 14 is an arc-shaped elastic body, one side of the arc of the elastic body is set toward the substrate 10, and the other side is in contact with the first connecting rod 131 and plays a role of elastic support for it. The connection methods of the elastic body and the substrate 10 include but are not limited to glue bonding, screw connection and hook connection. In the process of the pushing component 133 driving the first connecting rod 131 to move, the elastic body of the reset mechanism 14 is in a compressed state. After the force applied to the pushing component 133 is canceled, the elastic body drives the first connecting rod 131 to return to the initial position under the action of elastic potential energy, that is, the first engaging member 120 returns to a position where it can be engaged with the second engaging member 121, thereby realizing the function of automatic reset.

[0063] Specifically, the elastomer of the reset mechanism 14 includes but is not limited to silicone, thermoplastic polyurethanes (TPU), thermoplastic elastomers (TPE), steel and titanium alloy.

[0064] The number of elastic bodies of the reset mechanism 14 includes but is not limited to 1, 2, or 3. Figure 5 As shown, the resetting mechanism 14 includes only one elastic body.

[0065] In the display carrier 1000 provided in the embodiment of the present application, one first engaging member 120 is provided on the first connecting rod 131, and the number of the second engaging members 121 is at least two, and the at least two second engaging members 121 are provided in the sliding direction of the sliding housing 11.

[0066] The number of the first engaging members 120 disposed on the first connecting rod 131 is not specifically limited. For example, Figure 5 As shown, one first engaging member 120 is provided.

[0067] To facilitate the selection of the position where the sliding housing 11 is slidably fixed on the base plate 10, the number of the second engaging members 121 provided on the sliding housing 11 is not less than two, including but not limited to 3, 4, and 10. For example, Figure 1 As shown, ten second engaging members 121 are provided.

[0068] It should be noted that, in order to facilitate the adjustment of the relative position of the sliding shell 11, the second engaging members 121 can be arranged at equal intervals along the sliding direction of the sliding shell 11. In order to prevent the first engaging member 120 and the second engaging member 121 from being unable to engage with each other during the sliding process, the axis connecting the multiple second engaging members 121 is a straight line.

[0069] The display carrier 1000 provided in the embodiment of the present application has a receiving cavity 100 disposed inside the substrate 10, an opening 101 communicating with the receiving cavity 100 is disposed on the substrate 10, a first connecting rod 131 and a reset mechanism 14 are both disposed in the receiving cavity 100, and a first engaging member 120 passes through the opening 101 and engages with a second engaging member 121.

[0070] In order to prevent the substrate 10 and the sliding housing 11 from being interfered by other components when sliding relative to each other, the first connecting rod 131 and the reset mechanism 14 are arranged in the accommodating cavity 100 in the substrate 10, and an opening 101 is arranged so that the first engaging member 120 can engage with the second engaging member 121. The first engaging member 120 can only switch between two states, that is, away from the opening 101 and passing through the opening 101. Therefore, when setting, the position of the opening 101 is selected so that the first engaging member 120 can maintain the engagement with the second engaging member 121. The opening 101 is arranged with a diameter larger than the outer diameter of the first engaging member 120.

[0071] The opening 101 may be provided with only one hole-shaped structure. In order to improve the fault tolerance, it may also be provided as follows. Figure 1 , Figure 4 , Fig. 9 As shown, a strip-shaped opening 101 is provided, and the length direction of the strip-shaped opening 101 is consistent with the sliding direction of the sliding housing 11 .

[0072] The accommodating cavity 100 can be arranged along the sliding direction of the sliding housing 11. Fig. 9 As shown, it may be a channel structure penetrating the substrate 10 , and the accommodating cavity 100 has a space for accommodating the reciprocating motion of the first connecting rod 131 .

[0073] In the display carrier 1000 provided in the embodiment of the present application, the folding mechanism 15 includes a shaft 150 and two connecting pieces 151 pivotally connected to the shaft 150 , and the two substrates 10 are respectively connected to the two connecting pieces 151 .

[0074] The connecting piece 151 on the folding mechanism 15 can be directly connected to the surface of the base plate 10 , and the connection methods include but are not limited to screw connection, glue bonding, welding and hook connection.

[0075] In some embodiments, Fig. 9 As shown, a connection hole communicating with the accommodating cavity 100 may be provided on the surface of the substrate 10, a connecting column is provided in the accommodating cavity 100, the connecting piece 151 is fixedly connected to the connecting column, and the first connecting rod 131 is pivotally connected to the connecting column. Figure 5 As shown, a connecting ring is provided at the end of the first connecting rod 131, and the connecting ring is sleeved on the connecting column to realize the rotation connection of the first connecting rod 131.

[0076] The materials of the shaft 150 and the connecting piece 151 include but are not limited to steel, titanium alloy and plastic.

[0077] The folding mechanism 15 may include but is not limited to hinges and hinges.

[0078] In the display carrier 1000 provided in the embodiment of the present application, a pushing component 133 is arranged at the end of the shaft 150, and a through hole 102 connected to the accommodating cavity 100 is provided on the side of the substrate 10 close to the shaft 150. The second connecting rod 132 is rotatably connected to the pushing component 133, and the second connecting rod 132 extends into the accommodating cavity 100 through the through hole 102. The second connecting rod 132 and the connecting piece 151 rotate coaxially relative to the shaft 150.

[0079] It should be noted that the pushing component 133 may be a manual mechanical component, a hydraulic device controlled by a controller, or an electric device controlled by electricity, and no specific limitation is made here. Figure 5 As shown, the embodiment of the present application adopts a manual mechanical component, including a fixed part and a movable part. The fixed part can be set at an end of the substrate 10 away from the sliding shell 11. In this embodiment, it is set at the end of the shaft 150, and the movable part is connected to the fixed part. The movable part selects an elastic pressing key structure, and the elastic pressing key structure is used to push the second connecting rod 132 to move, and the second connecting rod 132 drives the first connecting rod 131 to move.

[0080] In this embodiment, the two second connecting rods 132 are connected to the same pushing component 133. The second connecting rods 132 pass through the through holes 102 of the respective substrates 10 and are connected to the fixed parts of the pushing component 133, so that one pushing component 133 can adjust the movement of the two first connecting rods 131 at the same time.

[0081] At the same time, since the two base plates 10 can be folded, the second connecting rod 132 and the pushing member 133 need to be rotatably connected. Figure 7 As shown, a connecting ring is provided at the end of the second connecting rod 132 of this embodiment. The second connecting rod 132 is connected between the fixed part and the movable part through the connecting ring. The outer diameter of the end of the movable part is larger than the inner diameter of the connecting ring. Therefore, when the movable part is pressed down, it can drive the second connecting rod 132 to move toward the fixed part.

[0082] The pushing component 133 can also be separately arranged outside each base plate 10 , and a linkage hole is provided on the base plate 10 , and a connecting piece is provided, and the connecting piece passes through the linkage hole to be separately linked with each first connecting rod 131 .
