[0002] With market demand for increased display space in electronic products like mobile phones, the electronics industry is experiencing a revolution in user experience driven by form factor innovation. The evolution of display screens in mobile phones and other electronic products from rigid to flexible, from small to large, and from static to dynamic, has brought new challenges to the housing structures that house these displays. In related technologies, the housings of rolling electronic devices experience unbalanced movement during the sliding process, resulting in poor closure or even inability to close. Summary of the Invention

[0006] a second housing, the second housing being slidably connected to the first housing; and

[0007] A balancing mechanism is located between the second shell and the first shell, and the balancing mechanism includes a first connecting rod assembly and a second connecting rod assembly. The first connecting rod assembly includes a first connecting end and a second connecting end, and the second connecting rod assembly includes a third connecting end and a fourth connecting end. The first connecting end and the third connecting end are spaced apart and are both movably connected to the first shell, and the second connecting end and the fourth connecting end are spaced apart and are both movably connected to the second shell. The connecting line between the first connecting end and the third connecting end is parallel to the connecting line between the second connecting end and the fourth connecting end.

[0008] On the other hand, the present application also provides an electronic device, including a flexible display screen and the shell device, wherein the flexible display screen includes a first display part and a second display part connected to each other, the first display part is fixedly connected to the first shell, and the second display part is unfolded or retracted as the second shell slides.

[0009] The shell device provided by the present application includes a first shell, a second shell and a balancing mechanism, the second shell can slide relative to the first shell, the first connecting end of the first connecting rod assembly and the third connecting end of the second connecting rod assembly of the balancing mechanism are movably connected to the first shell, and the second connecting end of the first connecting rod assembly and the fourth connecting end of the second connecting rod assembly are movably connected to the second shell. Since the first connecting end and the third connecting end are spaced apart, the second connecting end and the fourth connecting end are spaced apart, and the line between the first connecting end and the third connecting end is parallel to the line between the second connecting end and the fourth connecting end, the balancing mechanism can keep the second shell parallel to the first shell, so that the second shell slides smoothly and improves the closing effect of the shell device during the sliding process relative to the first shell. The electronic device provided by the present application includes a flexible display screen and the above-mentioned shell device, so the electronic device has high motion stability, good closing effect, and small appearance gap.

DETAILED DESCRIPTION

[0044] like Figure 1 As shown, in the prior art, scroll-type mobile phones suffer from problems such as an insufficient number of drive structures for driving the sliding member A and insufficient synchronization of the drive structures, which results in unbalanced movement of the sliding member A relative to the fixed member B. This causes the sliding member A to tilt when closed, affecting the closing effect. Therefore, the present application provides a housing device and electronic device that achieve smooth movement and improve the closing effect.

[0045] The technical solution of this application will be described clearly and completely below in conjunction with the accompanying drawings.

[0048] Please refer to Figure 2 and Figure 3 , Figure 2 This is a structural diagram of an electronic device 1000 provided in an embodiment of the present application when in an extended state. Figure 3 The following is a schematic diagram of the structure of an electronic device 1000 in a closed state, provided in an embodiment of the present application. The electronic device 1000 may be a mobile phone, tablet computer, cellular phone, media player, other handheld or portable electronic device, television, computer monitor, gaming device, navigation device, or the like, wherein the housing can slide and the display can scroll. In the embodiments of the present application, a sliding mobile phone is used as an example, including mobile phones that slide left and right to expand the display area and mobile phones that slide up and down to expand the display area. Here, sliding left and right can be understood as the electronic device 1000 being able to extend and close along its width; sliding up and down can be understood as the electronic device 1000 being able to extend and close along its length. The width direction of the electronic device 1000 can refer to the X-axis direction in the accompanying drawings; the length direction of the electronic device 1000 can refer to the Y-axis direction in the accompanying drawings; and the thickness direction of the electronic device 1000 can refer to the Z-axis direction in the accompanying drawings, which will not be described in detail later. The following embodiments take a sliding mobile phone as an example. The electronic device 1000 includes a flexible display 200 and a housing device 100.

[0049] Please refer to Figure 4 and Figure 5 , Figure 4 is a structural diagram of the flexible display screen 200 in an extended state, Figure 5Schematic diagram of the structure of the flexible display 200 in a closed state. When the flexible display 200 is in the extended state, the electronic device 1000 is in the extended state, and when the flexible display 200 is in the closed state, the electronic device 1000 is in the closed state. In one embodiment, the flexible display 200 includes a first display portion 201 and a second display portion 202 connected to each other. The first display portion 201 is a normal display portion, and the second display portion 202 is an extended display portion. It is understood that the first display portion 201 can display when the flexible display 200 is in the extended state or the closed state, and the second display portion 202 only displays when the flexible display 200 is in the extended state.

[0050] Please refer to Figure 6 and Figure 7 , Figure 6 is a schematic structural diagram of the housing device 100 in an extended state, Figure 7 This is a schematic diagram of the housing assembly 100 in a closed state. When the housing assembly 100 is extended, the electronic device 1000 is extended; when the housing assembly 100 is closed, the electronic device 1000 is closed. The housing assembly 100 is used to support the flexible display 200 and house electronic components (e.g., motherboard, battery, etc.). The housing assembly 100 includes a first housing 101 and a second housing 102.

[0051] In the present embodiment, the first housing 101 can be understood as a fixed housing. That is, when the housing device 100 switches between the extended state and the closed state, the first housing 101 remains stationary. The first display portion 201 of the flexible display 200 is fixed to the first housing 101. The second display portion 202 of the flexible display 200 expands or retracts as the second housing 102 slides.

[0052] The second housing 102 is slidably connected to the first housing 101. It will be appreciated that the second housing 102 can slide relative to the first housing 101 to move closer to or further away from the first housing 101. Optionally, the opposite ends of the second housing 102 are slidably connected to the opposite ends of the first housing 101. In one embodiment, the first housing 101 includes a first base plate 112 and a first peripheral side plate 113. The first peripheral side plate 113 is connected to the edge of the first base plate 112. The second housing 102 includes a second base plate 121 and a second peripheral side plate 122. The second peripheral side plate 122 is connected to the edge of the second base plate 121. The second base plate 121 of the second housing 102 can be slidably connected to the first base plate 112 of the first housing 101. The second peripheral side plate 122 of the second housing 102 can be slidably connected to the first peripheral side plate 113 of the first housing 101. In one possible embodiment, the first peripheral side plate 113 includes a first side wall 1130 and a second side wall 1131 disposed opposite each other along the Y-axis direction. The second peripheral side plate 122 includes a third side wall 1220 and a fourth side wall 1221 that are arranged opposite each other along the Y-axis. The third side wall 1220 is slidably connected to the first side wall 1130. The fourth side wall 1221 is slidably connected to the second side wall 1131. The first side wall 1130, the third side wall 1220, the fourth side wall 1221, and the second side wall 1131 can be arranged sequentially along the Y-axis, in which case the second shell 102 is slidably connected to the inner side of the first shell 101. Alternatively, the third side wall 1220, the first side wall 1130, the second side wall 1131, and the fourth side wall 1221 can be arranged sequentially along the Y-axis, in which case the second shell 102 is slidably connected to the outer side of the first shell 101. In this embodiment of the present application, the second shell 102 slides relative to the first shell 101 along the X-axis.

[0053] Please refer to Figure 8 and Figure 9The housing device 100 further includes at least one balancing mechanism 103. The balancing mechanism 103 is located between the second housing 102 and the first housing 101. The balancing mechanism 103 includes a first connecting rod assembly 130 and a second connecting rod assembly 131. The first connecting rod assembly 130 includes a first connecting end 130a and a second connecting end 130b. The second connecting rod assembly 131 includes a third connecting end 131a and a fourth connecting end 131b. The first connecting end 130a of the first connecting rod assembly 130 and the third connecting end 131a of the second connecting rod assembly 131 are spaced apart and are both movably connected to the first housing 101. The second connecting end 130b of the first connecting rod assembly 130 and the fourth connecting end 131b of the second connecting rod assembly 131 are spaced apart and are both movably connected to the second housing 102. Optionally, the distance between the first connecting end 130a and the third connecting end 131a can be equal to the distance between the second connecting end 130b and the fourth connecting end 131b. Of course, the spacing between the first connecting end 130a and the third connecting end 131a can also be dynamically changed, and the spacing between the second connecting end 130b and the fourth connecting end 131b can also be dynamically changed. The first connecting end 130a of the first connecting rod assembly 130 is slidably connected or rotatably connected to the first housing 101. The second connecting end 130b of the first connecting rod assembly 130 is slidably connected or rotatably connected to the second housing 102. The third connecting end 131a of the second connecting rod assembly 131 is slidably connected or rotatably connected to the first housing 101. The fourth connecting end 131b of the second connecting rod assembly 131 is slidably connected or rotatably connected to the second housing 102. The line connecting the first connecting end 130a and the third connecting end 131a is parallel (a slight deviation is allowed) to the line connecting the second connecting end 130b and the fourth connecting end 131b.

[0054] The balancing mechanism 103 can cause the second housing 102 to move parallel to or away from the first housing 101. It can be understood that since the line connecting the first connection end 130a and the third connection end 131a of the balancing mechanism 103 connected to the first housing 101 is parallel to the line connecting the second connection end 130b and the fourth connection end 131b of the balancing mechanism 103 connected to the second housing 102, the second housing 102 between the second connection end 130b and the fourth connection end 131b is parallel to the first housing 101 between the first connection end 130a and the third connection end 131a. Therefore, by designing the spacing between the first connection end 130a and the third connection end 131a, the spacing between the second connection end 130b and the fourth connection end 131b, and / or the number of balancing mechanisms 103, the second housing 102 can be made parallel to the first housing 101 during the sliding process, thereby causing the second housing 102 to move parallel to or away from the first housing 101.

[0055] This application does not specifically limit the number of balancing mechanisms 103. For example, the number of balancing mechanisms 103 can be one, two, or three. When there is one balancing mechanism 103, the balancing mechanism 103 can be located near the center of the second housing 102 along the Y-axis. When there are two balancing mechanisms 103, the balancing mechanisms 103 can be located near each end of the second housing 102 along the Y-axis. When there are three balancing mechanisms 103, the balancing mechanisms 103 can be arranged sequentially along the Y-axis and located near each end and the center of the second housing 102.

[0056] The housing device 100 provided in the present application includes a first housing 101, a second housing 102 and at least one balancing mechanism 103. The second housing 102 can slide relative to the first housing 101. The first connecting end 130a of the first connecting rod assembly 130 and the third connecting end 131a of the second connecting rod assembly 131 of the balancing mechanism 103 are movably connected to the first housing 101. The second connecting end 130b of the first connecting rod assembly 130 and the fourth connecting end 131b of the second connecting rod assembly 131 are movably connected to the second housing 102. 0a and the third connection end 131a are spaced apart, the second connection end 130b and the fourth connection end 131b are spaced apart, and the line between the first connection end 130a and the third connection end 131a is parallel to the line between the second connection end 130b and the fourth connection end 131b. Therefore, the balancing mechanism 103 can make the second shell 102 parallel to the first shell 101, so that the second shell 102 slides smoothly during the sliding process relative to the first shell 101, avoiding the second shell 102 from tilting, and improving the closing effect of the shell device 100. The electronic device 1000 provided in this application includes the flexible display screen 200 and the above-mentioned shell device 100. Therefore, the electronic device 1000 has high movement stability, good closing effect, and small appearance gap.

[0057] When the second housing 102 slides relative to the first housing 101, the balancing mechanism 103 expands or contracts along the sliding direction of the second housing 102. It will be appreciated that in this embodiment of the present application, the balancing mechanism 103 expands or contracts along the X-axis. Specifically, when the second housing 102 moves away from the first housing 101, the balancing mechanism 103 gradually expands. When the second housing 102 moves closer to the first housing 101, the balancing mechanism 103 gradually contracts.

[0058] Optionally, the first link assembly 130 includes a first link 1300, a first sliding member 1301 disposed at one end of the first link 1300, and a first rotating member 1302 disposed at the other end of the first link 1300. The second link assembly 131 includes a second link 1310, a second sliding member 1311 disposed at one end of the second link 1310, and a second rotating member 1312 disposed at the other end of the second link 1310. One of the first sliding member 1301 and the first rotating member 1302 includes a first connecting end 130a, and the other of the first sliding member 1301 and the first rotating member 1302 includes a second connecting end 130b. One of the second sliding member 1311 and the second rotating member 1312 includes a third connecting end 131a, and the other of the second sliding member 1311 and the second rotating member 1312 includes a fourth connecting end 131b.

[0059] In one embodiment, see Figure 10 and Figure 11 The first connecting rod assembly 130 and the second connecting rod assembly 131 of the balancing mechanism 103 are arranged crosswise and rotatably connected. The first connecting rod assembly 130a is slidably connected to the first housing 101, and the second connecting rod assembly 130b is rotatably connected to the second housing 102. The third connecting rod assembly 131a is rotatably connected to the first housing 101, and the fourth connecting rod assembly 131b is slidably connected to the second housing 102. The sliding direction of the first connecting rod 130a relative to the first housing 101 and the sliding direction of the fourth connecting rod 131b relative to the second housing 102 are parallel and perpendicular to the sliding direction of the second housing 102 relative to the first housing 101.

[0060] Please refer to Figures 10 to 12The first connecting rod assembly 130 includes a first connecting rod 1300, a first sliding member 1301 disposed at one end of the first connecting rod 1300, and a first rotating member 1302 disposed at the other end of the first connecting rod 1300. The first sliding member 1301 may include a slider, a slide rail, a slide groove, a slide rod, etc. The first sliding member 1301 and the first connecting rod 1300 may be integrally formed or fixedly connected in a detachable or non-detachable manner. The first rotating member 1302 may include a rotating shaft, an axial hole, a bearing, etc. The first rotating member 1302 and the first connecting rod 1300 may be integrally formed or fixedly connected in a detachable or non-detachable manner. The second connecting rod assembly 131 includes a second connecting rod 1310, a second sliding member 1311 disposed at one end of the second connecting rod 1310, and a second rotating member 1312 disposed at the other end of the second connecting rod 1310. The second sliding member 1311 may include a slider, a slide rail, a slide groove, a slide rod, etc. The second sliding member 1311 and the second connecting rod 1310 can be integrally formed or fixedly connected in a detachable or non-detachable manner. The second rotating member 1312 can include a rotating shaft, an axial hole, a bearing, etc. The second rotating member 1312 and the second connecting rod 1310 can be integrally formed or fixedly connected in a detachable or non-detachable manner.

[0061] The first connecting rod 1300 and the second connecting rod 1310 are intersectingly arranged and rotatably connected at the intersection. The first sliding member 1301 of the first connecting rod assembly 130 is slidably connected to the first housing 101. The connection between the first sliding member 1301 of the first connecting rod assembly 130 and the first housing 101 forms a first connection end 130a. The first rotating member 1302 of the first connecting rod assembly 130 is rotatably connected to the second housing 102. The connection between the first rotating member 1302 of the first connecting rod assembly 130 and the second housing 102 forms a second connection end 130b. The second rotating member 1312 of the second connecting rod assembly 131 is rotatably connected to the first housing 101. The connection between the second rotating member 1312 of the second connecting rod assembly 131 and the first housing 101 forms a third connection end 131a. The second sliding member 1311 of the second connecting rod assembly 131 is slidably connected to the second housing 102. The connection between the second sliding member 1311 of the second connecting rod assembly 131 and the second housing 102 forms a fourth connection end 131b.

[0062] The sliding direction of the first sliding member 1301 relative to the first housing 101 and the sliding direction of the second sliding member 1311 relative to the second housing 102 are parallel, and both are perpendicular to the sliding direction of the second housing 102 relative to the first housing 101. The parallel sliding direction of the first sliding member 1301 relative to the first housing 101 and the sliding direction of the second sliding member 1311 relative to the second housing 102 facilitates ensuring that the line connecting the first connecting end 130a and the third connecting end 131a remains parallel to the line connecting the second connecting end 130b and the fourth connecting end 131b during the sliding of the second housing 102 relative to the first housing 101. In the embodiment of the present application, the sliding directions of the first sliding member 1301 and the second sliding member 1311 are both along the Y-axis, and the sliding direction of the second housing 102 relative to the first housing 101 is along the X-axis. The first connecting rod 1300 and the second connecting rod 1310 are cross-arranged and rotationally connected at the intersection position. The sliding direction of the first sliding member 1301 and the sliding direction of the second sliding member 1311 are both along the Y-axis direction, which can make the expansion and contraction directions of the balancing mechanism 103 consistent with the sliding direction of the second shell 102 relative to the first shell 101, thereby facilitating the second shell 102 to slide relative to the first shell 101 and the movement of the balancing mechanism 103 between the second shell 102 and the first shell 101 through the same driving mechanism.

[0063] By making the balancing mechanism 103 include a first connecting rod assembly 130 and a second connecting rod assembly 131 that are cross-arranged and rotatably connected, and making the first connecting end 130a slidably connected to the first housing 101 and the fourth connecting end 131b slidably connected to the second housing 102, the balancing mechanism 103 can be deployed and retracted between the first housing 101 and the second housing 102. This allows the balancing mechanism 103 to be deployed between the first housing 101 and the second housing 102 when the housing device 100 is in an extended state, and to be retracted between the first housing 101 and the second housing 102 when the housing device 100 is in a closed state. In other words, in this embodiment, the balancing mechanism 103 can be driven to deploy and retract by the second housing 102. While achieving parallel sliding of the second housing 102 relative to the first housing 101, the number of driving mechanisms used to drive the second housing 102 and the balancing mechanism 103 can be reduced, thereby simplifying the structure of the housing device 100 and reducing the equipment load.

[0066] In this embodiment, by arranging a first sliding portion 114 and a first rotating portion 115 on the first shell 101 and a second sliding portion 124 and a second rotating portion 125 on the second shell 102, the first connecting end 130a of the first connecting rod assembly 130 can be directly slidably connected to the first shell 101, the second connecting end 130b of the first connecting rod assembly 130 can be directly rotationally connected to the second shell 102, the third connecting end 131a of the second connecting rod assembly 131 can be directly rotationally connected to the first shell 101, and the fourth connecting end 131b of the second connecting rod assembly 131 can be directly slidably connected to the second shell 102, thereby reducing the parts of the shell device 100, reducing the friction during the movement of the second shell 102 and the balancing mechanism 103, and reducing the load during the sliding process of the shell device 100. Among them, the extension direction of the first sliding portion 114 is the same as the extension direction of the second sliding portion 124, and the first sliding portion 114 and the second sliding portion 124 are respectively slidably connected to the first sliding member 1301 and the second sliding member 1311, which is beneficial to ensure that the line between the first connection end 130a and the third connection end 131a is always parallel to the line between the second connection end 130b and the fourth connection end 131b during the sliding of the second shell 102 relative to the first shell 101.

The first connecting end 130a of the first connecting rod assembly 130 is slidably connected to the third sliding portion 1320 of the first fixed link 132. The second connecting end 130b of the first connecting rod assembly 130 is rotationally connected to the fourth rotating portion 1331 of the second fixed link 133. The third connecting end 131a of the second connecting rod assembly 131 is rotationally connected to the third rotating portion 1321 of the first fixed link 132. The fourth connecting end 131b of the second connecting rod assembly 131 is slidably connected to the fourth sliding portion 1330 of the second fixed link 133.

One of the first rotating member 1302 and the fourth rotating portion 1331 may include a rotating shaft, and the other may include an axis hole. One of the second rotating member 1312 and the third rotating portion 1321 may include a rotating shaft, and the other may include an axis hole. One of the second sliding member 1311 and the fourth sliding portion 1330 may include a slide groove, and the other may include a slider, or one may include a slider and the other may include a slide rod. In one possible embodiment, the first sliding member 1301 is a slider. The first sliding member 1301 is fixed to one end of the first connecting rod 1300 by a connecting member (for example, a pin, a screw, etc.). The third sliding portion 1320 is a slide groove.

The fourth sliding portion 1330 is a sliding groove. The second sliding member 1311 is located in the fourth sliding portion 1330 and slides along the extension direction of the fourth sliding portion 1330.

[0070] In this embodiment, the provision of independent first and second fixed links 132, 133 relative to the first and second housings 101, 102 facilitates the machining of third and fourth sliding portions 1320, 1330, respectively, extending in the same direction, on the first and second fixed links 132, 133. The high degree of parallelism between the third and fourth sliding portions 1320, 1330 improves the parallelism accuracy between the sliding directions of the first and second link assembly 130, 131, thereby improving the parallelism accuracy of the second housing 102 relative to the first housing 101 during its sliding motion relative to the first housing 101. Furthermore, the flexible connection between the first and second link assembly 130 and the first housing 101 via the first fixed link 132, and the flexible connection between the second and second link assembly 131 and the first housing 101 via the second fixed link 133, increases the connection area between the balancing mechanism 103 and the first and second housings 101, 102, and further enhances the balancing effect and stability of the balancing mechanism 103 on the second housing 102.

[0071] Optional, such as Figure 15As shown, the housing device 100 further includes a first bearing assembly 104, a second bearing assembly 105, and a third bearing assembly 106. The first bearing assembly 104 includes a first rotating shaft 140 and a first bearing 141. The first connecting rod assembly 130 and the second connecting rod assembly 131 are rotatably connected via the first bearing assembly 104. In one embodiment, as Figure 16 As shown, the first connecting rod 1300 of the first connecting rod assembly 130 is provided with a first axial hole 1300a, and the second connecting rod 1310 of the second connecting rod assembly 131 is provided with a second axial hole 1301a. The first rotating shaft 140 is passed through the first axial hole 1300a and the second axial hole 1301a. The first bearing 141 includes a first sub-bearing and a second sub-bearing. The first sub-bearing is located in the first axial hole 1300a and is fixed between the first rotating shaft 140 and the first connecting rod 1300. The second sub-bearing is located in the second axial hole 1301a and is fixed between the second rotating shaft 150 and the second connecting rod 1310. The first connecting rod assembly 130 and the second connecting rod assembly 131 rotate around the first rotating shaft 140 through the first sub-bearing and the second sub-bearing respectively. The second bearing assembly 105 includes a second rotating shaft 150 and a second bearing 151. The first connecting rod assembly 130 and the second housing 102 are rotatably connected via the second bearing assembly 105. In one embodiment, please refer to Figure 17 and Figure 18 , the first rotating part 1302 of the first connecting rod assembly 130 is a third axial hole provided at the other end of the first connecting rod 1300. The second rotating portion 125 of the second housing 102 is a fourth axial hole, and the second rotating shaft 150 is passed through the third axial hole and the fourth axial hole. The second bearing 151 is located in the third axial hole and is fixed between the second rotating shaft 150 and the first connecting rod 1300. The first connecting rod assembly 130 rotates around the second rotating shaft 150 and the second housing 102 through the second bearing 151. The third bearing assembly 106 includes a third rotating shaft 160 and a third bearing 161. The second connecting rod assembly 131 is rotatably connected to the first housing 101 through the third bearing assembly 106. In one embodiment, please refer to Figure 19 and Figure 20 The second rotating member 1312 of the second connecting rod assembly 131 is a fifth axial hole provided at the other end of the second connecting rod 1310. The first rotating portion 115 of the first housing 101 is a sixth axial hole, and the third rotating shaft 160 is disposed within the fifth and sixth axial holes. The third bearing 161 is located within the fifth axial hole and is fixed between the third rotating shaft 160 and the second connecting rod 1310. The second connecting rod assembly 131 rotates about the third rotating shaft 160 and the first housing 101 via the third bearing 161. The first rotating shaft 140, the second rotating shaft 150, and the third rotating shaft 160 can all be pins, screws, or pins.

[0072] By opening holes in first connecting rod 1300 and second connecting rod 1310, which are respectively tightly fitted with the first and second sub-bearings, and are tightly connected via first rotating shaft 140, the first and second sub-bearings are enabled to rotate about their axes, thereby reducing friction during rotation of first connecting rod assemblies 130 and 131. A hole is opened at the other end of first connecting rod 1300, which is tightly fitted with second bearing 151. The hole is tightly fitted with second rotating shaft 150 and is tightly fitted with second housing 102. This allows first connecting rod assembly 130 to rotate about the axis of second bearing 151, while minimizing friction during rotation. A hole is opened at the other end of second connecting rod 1310, which is tightly fitted with third bearing 161. The hole is tightly fitted with first housing 101 via third rotating shaft 160, while minimizing friction during rotation of second connecting rod assembly 131. Since the friction of the balancing mechanism 103 is reduced during movement, the load of the driving mechanism 107 during operation of the housing device 100 can be reduced, and the balance of the second housing 102 during sliding relative to the first housing 101 can be improved.

[0073] In another embodiment, Figure 21 As shown, Figure 21 This is a schematic plan view of the structure of another housing device 100 provided in an embodiment of the present application. Unlike the housing device 100 in the aforementioned embodiment, the first connecting rod assembly 130 and the second connecting rod assembly 131 of the balancing mechanism 103 are arranged crosswise; the first connecting end 130a of the first connecting rod assembly 130 is slidably connected to the first housing 101, and the second connecting end 130b of the first connecting rod assembly 130 is rotationally connected to the second housing 102; the third connecting end 131a of the second connecting rod assembly 131 is slidably connected to the first housing 101, and the fourth connecting end 131b of the second connecting rod assembly 131 is rotationally connected to the second housing 102. It will be understood that in this embodiment, the balancing mechanism 103 and the first housing 101 are both slidably connected, and the balancing mechanism 103 and the second housing 102 are both rotationally connected. The sliding direction of the first connecting end 130a relative to the first housing 101 and the sliding direction of the third connecting end 131a relative to the first housing 101 are parallel to each other and perpendicular to the sliding direction of the second housing 102 relative to the first housing 101.

[0074] Please refer to Figure 21 and Figure 22The first connecting rod assembly 130 includes a first connecting rod 1300, a first sliding member 1301 disposed at one end of the first connecting rod 1300, and a first rotating member 1302 disposed at the other end of the first connecting rod 1300. The first sliding member 1301 may include a slider, a slide rail, a slide groove, etc. The first sliding member 1301 and the first connecting rod 1300 may be integrally formed or fixedly connected to each other in a detachable or non-detachable manner. The first rotating member 1302 may include a rotating shaft, an axis hole, etc. The first rotating member 1302 and the first connecting rod 1300 may be integrally formed or fixedly connected to each other in a detachable or non-detachable manner. The second connecting rod assembly 131 includes a second connecting rod 1310, a second sliding member 1311 disposed at one end of the second connecting rod 1310, and a second rotating member 1312 disposed at the other end of the second connecting rod 1310. The second sliding member 1311 may include a slider, a slide rail, a slide groove, etc. The second sliding member 1311 and the second connecting rod 1310 can be integrally formed or fixedly connected in a detachable or non-detachable manner. The second rotating member 1312 can include a rotating shaft, an axis hole, etc. The second rotating member 1312 and the second connecting rod 1310 can be integrally formed or fixedly connected in a detachable or non-detachable manner.

[0075] The first connecting rod 1300 and the second connecting rod 1310 are intersectingly arranged and contacting or spaced apart at the intersection. The first sliding member 1301 of the first connecting rod assembly 130 is slidably connected to the first housing 101. The connection between the first sliding member 1301 of the first connecting rod assembly 130 and the first housing 101 forms a first connecting end 130a. The first rotating member 1302 of the first connecting rod assembly 130 is rotatably connected to the second housing 102, and the connection between the first rotating member 1302 of the first connecting rod assembly 130 and the second housing 102 forms a second connecting end 130b. The second sliding member 1311 of the second connecting rod assembly 131 is slidably connected to the first housing 101. The connection between the second sliding member 1311 of the second connecting rod assembly 131 and the first housing 101 forms a third connecting end 131a. The second rotating member 1312 of the second connecting rod assembly 131 is rotatably connected to the second housing 102. The rotational connection between the second rotating member 1312 of the second connecting rod assembly 131 and the second housing 102 forms a fourth connecting end 131b. When the first link 1300 and the second link 1310 are spaced apart at the intersection, the motion interference between the first link 1300 and the second link 1310 can be reduced, the jamming of the balancing mechanism 103 can be reduced, and the reliability of the balancing mechanism 103 can be improved.

[0076] The sliding direction of the first sliding member 1301 and the sliding direction of the second sliding member 1311 are parallel to each other and perpendicular to the sliding direction of the second housing 102 relative to the first housing 101. The parallel sliding direction of the first sliding member 1301 and the sliding direction of the second sliding member 1311 facilitates ensuring that the line connecting the first connecting end 130a and the third connecting end 131a remains parallel to the line connecting the second connecting end 130b and the fourth connecting end 131b during the sliding of the second housing 102 relative to the first housing 101. In the embodiment of the present application, the sliding directions of the first sliding member 1301 and the second sliding member 1311 are both along the Y-axis, and the sliding direction of the second housing 102 relative to the first housing 101 is along the X-axis. The first connecting rod 1300 and the second connecting rod 1310 are cross-arranged and contact or spaced apart at the intersection position. The sliding direction of the first sliding member 1301 and the sliding direction of the second sliding member 1311 are both along the Y-axis direction, which can make the expansion and contraction directions of the balancing mechanism 103 consistent with the sliding direction of the second shell 102 relative to the first shell 101, thereby facilitating the movement of the second shell 102 relative to the first shell 101 and the balancing mechanism 103 between the second shell 102 and the first shell 101 through the same driving mechanism 107.

[0077] By making the balancing mechanism 103 include a first connecting rod assembly 130 and a second connecting rod assembly 131 arranged in a cross-connection manner, and making the first connecting end 130a slidably connected to the first housing 101, and the third connecting end 131a slidably connected to the first housing 101, the balancing mechanism 103 can be deployed and retracted between the first housing 101 and the second housing 102. As a result, the balancing mechanism 103 can be deployed between the first housing 101 and the second housing 102 when the housing device 100 is in an extended state, and can be retracted between the first housing 101 and the second housing 102 when the housing device 100 is in a closed state. In other words, in this embodiment, the balancing mechanism 103 can be driven to deploy and retract by the second housing 102. While achieving parallel sliding of the second housing 102 relative to the first housing 101, the number of driving mechanisms 107 used to drive the second housing 102 and the balancing mechanism 103 can be reduced, thereby simplifying the structure of the housing device 100 and reducing the equipment load.

[0078] In one embodiment, if Figure 23As shown, the first housing 101 has a fifth sliding portion 116 and a sixth sliding portion 117 spaced apart. The fifth sliding portion 116 extends in the same direction as the sixth sliding portion 117. In this embodiment, the extension directions of the fifth sliding portion 116 and the sixth sliding portion 117 are both perpendicular to the sliding direction of the second housing 102 relative to the first housing 101. That is, the extension directions of the fifth sliding portion 116 and the sixth sliding portion 117 are both parallel to the Y-axis. The second housing 102 has a fifth rotating portion 126 and a sixth rotating portion 127 spaced apart. The first connecting end 130a of the first connecting rod assembly 130 is slidably connected to the fifth sliding portion 116 of the first housing 101. The second connecting end 130b of the first connecting rod assembly 130 is slidably connected to the fifth rotating portion 126 of the second housing 102. The third connecting end 131a of the second connecting rod assembly 131 is slidably connected to the sixth sliding portion 117 of the first housing 101. The fourth connecting end 131b of the second connecting rod assembly 131 is rotatably connected to the sixth rotating portion 127 of the second housing 102. It will be appreciated that the first sliding member 1301 is slidably connected to the fifth sliding portion 116 of the first housing 101. The first rotating member 1302 is rotatably connected to the fifth rotating portion 126 of the second housing 102. The second sliding member 1311 is rotatably connected to the sixth sliding portion 117 of the first housing 101. The second rotating member 1312 is rotatably connected to the sixth rotating portion 127 of the second housing 102.

One of the first rotating member 1302 and the fifth rotating portion 126 may include a rotating shaft, and the other may include an axial hole. One of the second sliding member 1311 and the sixth sliding portion 117 may include a sliding groove, and the other may include a slider. One of the second rotating member 1312 and the sixth rotating portion 127 may include a rotating shaft, and the other may include an axial hole. In one embodiment, the first sliding member 1301 is a slider. The first sliding member 1301 is fixed to one end of the first connecting rod 1300 via a connecting member (e.g., a pin, screw, etc.). The fifth sliding portion 116 is a sliding groove. The first sliding member 1301 is located within the fifth sliding portion 116 and slides along the extension direction of the fifth sliding portion 116. The first rotating member 1302 includes a rotating shaft, and the fifth rotating portion 126 includes an axial hole. The first rotating member 1302 extends through the fifth rotating portion 126 to rotate about the axis of the fifth rotating portion 126. The second sliding member 1311 is a slider. The second sliding member 1311 is secured to one end of the second connecting rod 1310 via a connector (e.g., a pin, screw, etc.). The sixth sliding portion 117 is a sliding groove. The second sliding member 1311 is positioned within the sixth sliding portion 117 and slides along the extension direction of the sixth sliding portion 117. The second rotating member 1312 includes a rotating shaft, and the sixth rotating portion 127 includes an axial hole. The second rotating member 1312 extends through the sixth rotating portion 127 to rotate about the axis of the sixth rotating portion 127.

[0080] In this embodiment, by arranging the fifth sliding part 116 and the sixth sliding part 117 on the first shell 101 and the fifth rotating part 126 and the sixth rotating part 127 on the second shell 102, the first connecting end 130a of the first connecting rod assembly 130 can be directly slidably connected to the first shell 101, the second connecting end 130b of the first connecting rod assembly 130 can be directly rotationally connected to the second shell 102, the third connecting end 131a of the second connecting rod assembly 131 can be directly slidably connected to the first shell 101, and the fourth connecting end 131b of the second connecting rod assembly 131 can be directly rotationally connected to the second shell 102, thereby reducing the parts of the shell device 100, reducing the friction during the movement of the second shell 102 and the balancing mechanism 103, and reducing the load during the sliding process of the shell device 100. Among them, the extension direction of the fifth sliding portion 116 is the same as the extension direction of the sixth sliding portion 117, and the fifth sliding portion 116 and the sixth sliding portion 117 are respectively slidably connected to the first sliding member 1301 and the second sliding member 1311, which is beneficial to ensure that the line between the first connection end 130a and the third connection end 131a is always parallel to the line between the second connection end 130b and the fourth connection end 131b during the sliding of the second shell 102 relative to the first shell 101.

[0081] In another embodiment, please refer to Figure 24 and Figure 25 The balancing mechanism 103 further includes a third fixing link 134 and a fourth fixing link 135. The third fixing link 134 is fixed to the first shell 101. Optionally, the third fixing link 134 is connected to the first shell 101 by a detachable or non-detachable connection. For example, the third fixing link 134 can be fixed to the first shell 101 by welding, bonding, threading, snap-fit ​​connection, etc. The third fixing link 134 can be a long bar, a cylindrical bar, etc. The fourth fixing link 135 is fixed to the second shell 102. Optionally, the fourth fixing link 135 is connected to the second shell 102 by a detachable or non-detachable connection. For example, the fourth fixing link 135 can be fixed to the second shell 102 by welding, bonding, threading, snap-fit ​​connection, etc. The fourth fixing link 135 can be a long bar, a cylindrical bar, etc.

[0082] The third fixed link 134 has a seventh sliding portion 1340 and an eighth sliding portion 1341 spaced apart from each other. The seventh sliding portion 1340 extends in the same direction as the eighth sliding portion 1341. In this embodiment, the seventh sliding portion 1340 and the eighth sliding portion 1341 extend perpendicular to the sliding direction of the second housing 102 relative to the first housing 101. That is, the seventh sliding portion 1340 and the eighth sliding portion 1341 extend in parallel with the Y-axis. The fourth fixed link 135 has a seventh rotating portion 1350 and an eighth rotating portion 1351 spaced apart from each other. The first connecting end 130a of the first link assembly 130 is slidably connected to the seventh sliding portion 1340 of the third fixed link 134. The second connecting end 130b of the first link assembly 130 is slidably connected to the seventh rotating portion 1350 of the fourth fixed link 135. The third connecting end 131a of the second link assembly 131 is slidably connected to the eighth sliding portion 1341 of the third fixed link 134. The fourth connecting end 131b of the second connecting rod assembly 131 is rotatably connected to the eighth rotating portion 1351 of the fourth fixed link 135. It will be appreciated that the first sliding member 1301 is slidably connected to the seventh sliding portion 1340 of the third fixed link 134. The first rotating member 1302 is rotatably connected to the seventh rotating portion 1350 of the fourth fixed link 135. The second sliding member 1311 is slidably connected to the eighth sliding portion 1341 of the third fixed link 134. The second rotating member 1312 is rotatably connected to the eighth rotating portion 1351 of the fourth fixed link 135.

[0083] One of the first sliding member 1301 and the seventh sliding part 1340 may include a slide groove, and the other includes a slider. One of the first rotating member 1302 and the seventh rotating part 1350 may include a rotating shaft, and the other includes an axis hole. One of the second sliding member 1311 and the eighth sliding part 1341 may include a slide groove, and the other includes a slider. One of the second rotating member 1312 and the eighth rotating part 1351 may include a rotating shaft, and the other includes an axis hole. In one embodiment, the first sliding member 1301 is a slider. The first sliding member 1301 is fixed to one end of the first connecting rod 1300 by a connecting member (for example, a pin, a screw, etc.). The seventh sliding part 1340 is a slide groove. The first sliding member 1301 is located in the seventh sliding part 1340 and slides along the extension direction of the seventh sliding part 1340. The first rotating member 1302 includes a rotating shaft, the seventh rotating part 1350 includes an axial hole, and the first rotating member 1302 passes through the seventh rotating part 1350 to rotate around the axis of the seventh rotating part 1350. The second sliding member 1311 is a slider. The second sliding member 1311 is fixed to one end of the second connecting rod 1310 by a connecting member (for example, a pin, a screw, etc.). The eighth sliding part 1341 is a sliding groove. The second sliding member 1311 is located in the eighth sliding part 1341 and slides along the extension direction of the eighth sliding part 1341. The second rotating member 1312 includes a rotating shaft, the eighth rotating part 1351 includes an axial hole, and the second rotating member 1312 passes through the eighth rotating part 1351 to rotate around the axis of the eighth rotating part 1351.

[0084] In this embodiment, the provision of a third fixed link 134 and a fourth fixed link 135, which are independent of the first housing 101 and the second housing 102, facilitates the processing of a seventh sliding portion 1340 and an eighth sliding portion 1341, respectively, extending in the same direction, on the third fixed link 134 and the fourth fixed link 135. The seventh sliding portion 1340 and the eighth sliding portion 1341 are highly parallel, thereby improving the parallelism accuracy of the sliding directions of the first link assembly 130 and the second link assembly 131. This improves the parallelism accuracy of the second housing 102 relative to the first housing 101 during its sliding motion relative to the first housing 101. Furthermore, the articulation between the first link assembly 130 and the first housing 101 via the third fixed link 134 and the articulation between the second link assembly 131 and the first housing 101 via the fourth fixed link 135 increases the connection area between the balancing mechanism 103 and the first and second housings 101, 102, further enhancing the balancing effect and stability of the balancing mechanism 103 on the second housing 102.

[0085] Optionally, the housing device 100 further includes a fourth bearing assembly and a fifth bearing assembly. The fourth bearing assembly includes a fourth rotating shaft and a fourth bearing. The second connecting end 130b of the first connecting rod assembly 130 is rotatably connected to the second housing 102 via the fourth bearing assembly. In one embodiment, the first rotating member 1302 of the first connecting rod assembly 130 is a seventh axial hole provided at the other end of the first connecting rod 1300. The fifth rotating portion 126 of the second housing 102 or the seventh rotating portion 1350 of the fourth fixed link 135 is an eighth axial hole, and the fourth rotating shaft is disposed within the seventh and eighth axial holes. The second bearing 151 is fixed between the fourth rotating shaft and the first connecting rod 1300. The first connecting rod assembly 130 rotates about the fourth rotating shaft and the second housing 102 via the second bearing 151. The fifth bearing assembly includes a fifth rotating shaft and a fifth bearing. The second connecting rod assembly 131 is rotatably connected to the second housing 102 via the fifth bearing assembly. In one embodiment, the second rotating member 1312 of the second connecting rod assembly 131 is a ninth axial hole located at the other end of the second connecting rod 1310. The sixth rotating portion 127 of the second housing 102 or the eighth rotating portion 1351 of the fourth fixed link 135 is a tenth axial hole, and the fifth rotating shaft is disposed within the ninth and tenth axial holes. A fifth bearing is fixed between the fifth rotating shaft and the second connecting rod 1310. The second connecting rod assembly 131 rotates about the fifth rotating shaft and the second housing 102 via the fifth bearing. Both the fourth and fifth rotating shafts may be pins, screws, or other similar structures.

[0086] By opening a hole at the other end of the first connecting rod 1300, which is tightly fitted with the fourth bearing, and tightly fitted with the second housing 102 via the fourth rotating shaft, the first connecting rod assembly 130 can rotate about the axis of the second bearing 151, while reducing friction during rotation. By opening a hole at the other end of the second connecting rod 1310, which is tightly fitted with the fifth bearing, and tightly fitted with the first housing 101 via the fifth rotating shaft, the second connecting rod assembly 131 can rotate about the axis of the fifth bearing, while reducing friction during rotation. By reducing friction during the movement of the balancing mechanism 103, the load on the drive mechanism 107 during operation of the housing device 100 can be reduced, improving the balance of the second housing 102 during sliding relative to the first housing 101.

[0087] like Figure 26 As shown, Figure 26The following is a schematic plan view of the structure of another housing device 100 provided in an embodiment of the present application. Unlike the housing device 100 in the aforementioned embodiment, the first connecting rod assembly 130 and the second connecting rod assembly 131 of the balancing mechanism 103 are arranged crosswise; the first connecting end 130a of the first connecting rod assembly 130 is rotationally connected to the first housing 101, and the second connecting end 130b of the first connecting rod assembly 130 is slidably connected to the second housing 102; the third connecting end 131a of the second connecting rod assembly 131 is rotationally connected to the first housing 101, and the fourth connecting end 131b of the second connecting rod assembly 131 is slidably connected to the second housing 102. It will be understood that in this embodiment, the balancing mechanism 103 and the first housing 101 are both rotationally connected, and the balancing mechanism 103 and the second housing 102 are both slidably connected. The sliding directions of the second connecting end 130b and the fourth connecting end 131b relative to the second housing 102 are parallel to each other and perpendicular to the sliding direction of the second housing 102 relative to the first housing 101. In this embodiment, the cross-arrangement of the first connecting rod assembly 130 and the second connecting rod assembly 131, the sliding connection and rotation connection between the first connecting rod assembly 130 and the first shell 101, and the sliding connection and rotation connection between the second connecting rod assembly 131 and the second shell 102 can correspond to the above embodiments and will not be repeated here. This embodiment can also realize the expansion and contraction of the balancing mechanism 103 between the first shell 101 and the second shell 102 through the cross-arranged first connecting rod assembly 130 and the second connecting rod assembly 131, so that the balancing mechanism 103 can be expanded between the first shell 101 and the second shell 102 when the shell device 100 is in the extended state, and can be contracted between the first shell 101 and the second shell 102 when the shell device 100 is in the closed state. That is, the balancing mechanism 103 can be driven to expand and contract by the second shell 102. While realizing the parallel sliding of the second shell 102 relative to the first shell 101, the number of driving mechanisms 107 for driving the second shell 102 and the balancing mechanism 103 can be reduced, thereby simplifying the structure of the shell device 100 and reducing the equipment load.

[0088] like Figure 27 As shown, Figure 27A schematic diagram of the planar structure of another shell device 100 provided in an embodiment of the present application. The difference from the shell device 100 in the above embodiment is that the first connecting end 130a is rotatably connected to the first shell 101, the second connecting end 130b is rotatably connected to the second shell 102, the third connecting end 131a is rotatably connected to the first shell 101, and the fourth connecting end 131b is rotatably connected to the second shell 102. The balancing mechanism 103 also includes a third connecting rod assembly 136 located between the first shell 101 and the second shell 102. The third connecting rod assembly 136 is not connected to the first shell 101 and the second shell 102. In other words, the third connecting rod assembly 136 can be suspended. The first connecting rod assembly 130 also includes a fifth connecting end 130c and a sixth connecting end 130d located between the first connecting end 130a and the second connecting end 130b and spaced apart. The second connecting rod assembly 131 also includes a seventh connecting end 131c and an eighth connecting end 131d spaced apart between the third connecting end 131a and the fourth connecting end 131b. The fifth connecting end 130c, the sixth connecting end 130d, the seventh connecting end 131c, and the eighth connecting end 131d are all slidably connected to the third connecting rod assembly 136. The sliding directions of the fifth connecting end 130c, the sixth connecting end 130d, the seventh connecting end 131c, and the eighth connecting end 131d are all parallel to each other. In this embodiment, the fifth connecting end 130c, the sixth connecting end 130d, the seventh connecting end 131c, and the eighth connecting end 131d are all slidably connected to the third connecting rod assembly 136 and are able to slide relative to the third connecting rod assembly 136 in a direction perpendicular to the sliding direction of the second housing 102 relative to the first housing 101.

[0089] The fifth connecting end 130c can be slidably connected to the third connecting rod assembly 136 by the cooperation of the slider and the slide groove, or the cooperation of the slider and the slide rail. The sixth connecting end 130d can be slidably connected to the third connecting rod assembly 136 by the cooperation of the slider and the slide groove, or the cooperation of the slider and the slide rail. The seventh connecting end 131c can be slidably connected to the third connecting rod assembly 136 by the cooperation of the slider and the slide groove, or the cooperation of the slider and the slide rail. The eighth connecting end 131d can be slidably connected to the third connecting rod assembly 136 by the cooperation of the slider and the slide groove, or the cooperation of the slider and the slide rail.

[0090] The balancing mechanism 103 of this embodiment can also be expanded and retracted between the first shell 101 and the second shell 102, and the expansion direction of the balancing mechanism 103 is the same as the direction in which the second shell 102 slides relative to the first shell 101 and moves away from the first shell 101, and the retraction direction of the balancing mechanism 103 is the same as the direction in which the second shell 102 slides relative to the first shell 101 and approaches the first shell 101, that is, the expansion and retraction of the balancing mechanism 103 are consistent with the extension and closure of the second shell 102, which is conducive to driving the balancing mechanism 103 to expand and retract through the second shell 102. While realizing the parallel sliding of the second shell 102 relative to the first shell 101, the number of driving mechanisms 107 for driving the second shell 102 and the balancing mechanism 103 can be reduced, thereby simplifying the structure of the shell device 100 and reducing the equipment load.

[0091] Please refer to Figure 27 and Figure 28 The first connecting rod assembly 130 includes a third connecting rod 1303, a fourth connecting rod 1304, a fifth connecting rod 1305, and a sixth connecting rod 1306, which are rotatably connected in sequence. The third connecting rod 1303, the fourth connecting rod 1304, the fifth connecting rod 1305, and the sixth connecting rod 1306 can form a parallelogram. The rotatable connection between the third connecting rod 1303 and the fourth connecting rod 1304 forms a first connecting end 130a. The rotatable connection between the fourth connecting rod 1304 and the fifth connecting rod 1305 forms a fifth connecting end 130c. The rotatable connection between the fifth connecting rod 1305 and the sixth connecting rod 1306 forms a second connecting end 130b. The rotatable connection between the sixth connecting rod 1306 and the third connecting rod 1303 forms a sixth connecting end 130d. The second connecting rod assembly 131 includes a seventh connecting rod 1313, an eighth connecting rod 1314, a ninth connecting rod 1315, and a tenth connecting rod 1316, which are rotatably connected in sequence. The seventh connecting rod 1313, the eighth connecting rod 1314, the ninth connecting rod 1315, and the tenth connecting rod 1316 can form a parallelogram. The rotatable connection between the seventh connecting rod 1313 and the eighth connecting rod 1314 forms a third connecting end 131a. The rotatable connection between the eighth connecting rod 1314 and the ninth connecting rod 1315 forms a seventh connecting end 131c. The rotatable connection between the ninth connecting rod 1315 and the tenth connecting rod 1316 forms a fourth connecting end 131b. The rotatable connection between the tenth connecting rod 1316 and the seventh connecting rod 1313 forms an eighth connecting end 131d.

[0092] By making the first link assembly 130 include a third link 1303, a fourth link 1304, a fifth link 1305 and a sixth link 1306 that are rotatably connected in sequence, the rotational connection between the third link 1303 and the fourth link 1304 forms a first connection end 130a, the rotational connection between the fourth link 1304 and the fifth link 1305 forms a fifth connection end 130c, the rotational connection between the fifth link 1305 and the sixth link 1306 forms a second connection end 130b, and the rotational connection between the sixth link 1306 and the third link 1303 forms a sixth connection end 130d. While realizing parallel sliding of the second shell 102 relative to the first shell 101, it is beneficial to simplify the sliding connection between the first link assembly 130 and the third link assembly 136, thereby facilitating the processing and assembly of the first link assembly 130 and the third link assembly 136. By making the second connecting rod assembly 131 include the seventh connecting rod 1313, the eighth connecting rod 1314, the ninth connecting rod 1315 and the tenth connecting rod 1316 which are rotatably connected in sequence, the rotational connection between the seventh connecting rod 1313 and the eighth connecting rod 1314 forms the third connecting end 131a, the rotational connection between the eighth connecting rod 1314 and the ninth connecting rod 1315 forms the seventh connecting end 131c, the rotational connection between the ninth connecting rod 1315 and the tenth connecting rod 1316 forms the fourth connecting end 131b, and the rotational connection between the tenth connecting rod 1316 and the seventh connecting rod 1313 forms the eighth connecting end 131d. While realizing the parallel sliding of the second shell 102 relative to the first shell 101, it is beneficial to simplify the sliding connection between the second connecting rod assembly 131 and the third connecting rod assembly 136, and simplify the sliding connection between the second connecting rod assembly 131 and the third connecting rod assembly 136, thereby facilitating the processing and assembly of the second connecting rod assembly 131 and the third connecting rod assembly 136. In addition, the third link 1303, the fourth link 1304, the fifth link 1305 and the sixth link 1306 form a parallelogram, and the seventh link 1313, the eighth link 1314, the ninth link 1315 and the tenth link 1316 form a parallelogram, so that the second shell 102 always remains parallel to the first shell 101 during the sliding process relative to the first shell 101, and the sliding of the second shell 102 is smoother.

[0093] Furthermore, if Figure 29As shown, the electronic device 1000 provided in an embodiment of the present application also includes a drive mechanism 107. The drive mechanism 107 is fixed to the first shell 101, and the drive mechanism 107 is connected to the second shell 102. The drive mechanism 107 is used to drive the second shell 102 to slide relative to the first shell 101. The drive mechanism 107 can be driven by electric drive or electromagnetic drive to drive the second shell 102 to slide relative to the first shell 101. The drive mechanism 107 can include a motor and a transmission assembly connected between the motor and the second shell 102 (for example: a push rod assembly, a connecting rod assembly, a cam assembly, a gear rack assembly, etc.). In one embodiment, the drive mechanism 107 includes a motor and a push rod assembly. The motor is used to provide a power source. The push rod assembly is used to connect the motor and the second shell 102 to push the second shell 102 away from the first shell 101 under the drive of the motor, or to pull the second shell 102 closer to the first shell 101.

[0094] By providing the driving mechanism 107 , the second housing 102 can be automatically extended and retracted relative to the first housing 101 , thereby improving the automation and intelligence of the electronic device 1000 .

[0095] In particular, the drive mechanism 107 can deviate from the center line of the first shell 101 in a direction perpendicular to the sliding direction of the second shell 102 relative to the first shell 101. It is understandable that in the embodiment of the present application, the drive mechanism 107 can deviate from the center line of the first shell 101 along the Y-axis direction. In other words, the drive mechanism 107 is not arranged at the center position of the first shell 101. By allowing the drive mechanism 107 to deviate from the center line of the first shell 101 in a direction perpendicular to the sliding direction of the second shell 102 relative to the first shell 101, it is beneficial to install a larger capacity battery in the first shell 101, thereby improving the battery life of the electronic device 1000. The balancing mechanism 103 can be arranged on the side of the center line of the first shell 101 away from the drive mechanism 107. In one embodiment, the drive mechanism 107 can be located between the central axis of the first shell 101 and the first side wall 1130 of the first shell 101. The first connection end 130a and the second connection end 130b of the balancing mechanism 103 can be located between the central axis of the first housing 101 and the second sidewall 1131 of the first housing 101. In other words, the drive mechanism 107 and the balancing mechanism 103 are located on either side of the centerline of the electronic device 1000 along the Y-axis. In this embodiment, the drive mechanism 107 can drive the second housing 102 to slide relative to the first housing 101, thereby achieving the expansion and closure of the housing device 100. When the drive mechanism 107 drives the second housing 102 to slide relative to the first housing 101, the balancing mechanism 103 can be driven by the second housing 102 to expand or close, thereby maintaining balance between the second housing 102 and the first housing 101 during the sliding process. This facilitates the design of a scroll-type electronic device 1000 with a larger Y-axis dimension. The balancing mechanism 103 and the drive mechanism 107 are separated along the Y-axis, which further facilitates the balancing mechanism 103 compensating for the movement of the second housing 102, thereby maintaining balance relative to the first housing 101.

[0096] In addition, please refer to Figure 30 and Figure 31 The electronic device 1000 further includes a support assembly 300. The support assembly 300 includes a first support member 118 and a second support member 301. The first support member 118 is disposed between the first housing 101 and the first display portion 201 of the flexible display 200. The first support member 118 and the first housing 101 may be integrally formed or connected as one piece. The first support member 118 is used to support the first display portion 201 of the flexible display 200. The first support member 118 may be a support structure formed by a support plate or a plurality of support rods in a frame-like, grid-like, or comb-like shape.

[0097] The second support member 301 is connected between the first housing 101 and the second housing 102, and is flush with the first support member 118. In one embodiment, the second support member 301 is connected between the side of the first support member 118 facing the second housing 102 and the side of the second housing 102 facing the first support member 118. The side of the first support member 118 facing the second housing 102 and the side of the second housing 102 facing the first support member 118 are arranged opposite each other along the X-axis. As the second housing 102 slides relative to the first housing 101, the second support member 301 is driven by the second housing 102 to expand or contract. When the electronic device 1000 is in the extended state, the second display portion 202 is expanded and supported on the second support member 301. When the electronic device 1000 is in the closed state, the second display portion 202 is retracted into the electronic device 1000.

[0098] By providing the support assembly 300, the first display portion 201 and the second display portion 202 of the flexible display 200 are supported on the first support member 118 and the second support member 301 of the support assembly 300, respectively, when in the extended state. Since the first support member 118 is flush with the second support member 301, the height difference between the first display portion 201 and the second display portion 202 of the flexible display 200 can be reduced, thereby improving the display effect of the flexible display 200 and reducing the step difference when pressing the flexible display 200. In addition, by directly connecting the support assembly 300 between the first shell 101 and the second shell 102, the thickness of the first shell 101 and the second shell 102 can be reduced compared to a comb-shaped support structure that slides the first shell 101, thereby facilitating the thinning and lightening of the electronic device 1000.

[0099] In one embodiment, the support assembly 300 includes a plurality of second support members 301. The second support members 301 include first support rods 310 and second support rods 311 arranged crosswise and rotatably connected. The first support rods 310 of two adjacent second support members 301 are arranged in parallel, and the second support rods 311 of two adjacent second support members 301 are arranged in parallel. One end of the first support rod 310 of one of the two adjacent second support members 301 is rotatably connected to one end of the second support rod 311 of the other second support member 301, and one end of the second support rod 311 of one of the second support members 301 is rotatably connected to one end of the first support rod 310 of the other second support member 301. The first support rod 310 and second support rod 311 of the second support member 301 at the edge of the support assembly 300 near the first housing 101 are fixedly connected to the first housing 101, while the first support rod 310 and second support rod 311 of the second support member 301 at the edge near the second housing 102 are fixedly connected to the second housing 102.

[0100] The support assembly 300 of this embodiment can be expanded or retracted under the drive of the second housing 102 , so as to support flexible display screens 200 with different areas when the electronic device 1000 is in an extended state and a closed state.

[0101] Furthermore, the electronic device 1000 may also include an electrical connection assembly. The electrical connection assembly may include a flexible circuit board, wiring, etc. At least part of the electrical connection assembly is fixed to the balancing mechanism 103 of the housing device 100. The electrical connection assembly is used to electrically connect multiple electronic components between the first housing 101 and the second housing 102. The multiple electronic components between the first housing 101 and the second housing 102 may include a motherboard, other circuit boards, an earpiece, a speaker, a camera module, various sensors, an antenna, a vibrator, etc. By fixing the electrical connection assembly to the balancing mechanism 103, the reliability of the electrical connection of the multiple electronic components can be improved.

[0102] The housing device 100 and electronic device 1000 provided in the present application are provided with a balancing mechanism 103 between the first housing 101 and the second housing 102. The balancing mechanism 103 can make the second housing 102 parallel to the first housing 101 during the sliding process of the second housing 102 relative to the first housing 101, thereby preventing the second housing 102 from tilting, thereby improving the movement stability and appearance closure effect of the housing device 100 and the electronic device 1000. The balancing mechanism 103 includes a first connecting rod assembly 130 and a second connecting rod assembly 131. The structure of the balancing mechanism 103 is simple, which is conducive to the installation and disassembly of the housing device 100 and the electronic device 1000.
