The dimensioning of the first and

second spindle assemblies

2, 3 is exemplified below.

Referring to fig. 3A to 3C, fig. 3A is a schematic view of the housing device 100 shown in fig. 1A at another angle, fig. 3B is a schematic view of the housing device 100 shown in fig. 1B at another angle, and fig. 3C is a schematic view of the housing device 100 shown in fig. 1C at another angle.

In the present embodiment, a plane on which the upper end of the second housing 12 is located is defined as a reference plane, and a direction perpendicular to the reference plane is defined as a thickness direction of the housing apparatus 100. The upper end of the second casing 12 may be the end point of the rib structure or a flat upper surface. When the housing device 100 is in the open state, the first housing 11 and the second housing 12 are in the open state, the second housing 12 and the third housing 13 are in the open state, the upper end of the first housing 11 and the upper end of the third housing 13 are flush with the upper end of the second housing 12, and the upper end of the first housing 11 and the upper end of the third housing 13 are also located in the reference plane. When the housing device 100 is in the first closed state, the upper end of the first housing 11 may be close to the upper end of the second housing 12, and the plane on which the upper end of the first housing 11 is located is parallel to the reference plane. When the housing assembly 100 is in the second closed state, the upper end of the third housing 13 may be close to the lower end of the first housing 11, and the plane of the upper end of the third housing 13 is parallel to the reference plane.

In the present embodiment, the first shaft assembly 2 has a first appearance surface 300 and defines a maximum dimension of the first appearance surface 300 in the thickness direction as a first thickness, and the second shaft assembly 3 has a second appearance surface 400 and defines a maximum dimension of the second appearance surface 400 in the thickness direction as a second thickness. When the housing device 100 is in the open state, the first housing 11 and the second housing 12 together cover the first appearance surface 300 of the first rotating shaft assembly 2, and the second housing 12 and the third housing 13 together cover the second appearance surface 400 of the second rotating shaft assembly 3. When the casing device 100 is in the first closed state and the second closed state, the first appearance surface 300 of the first rotating shaft assembly 2 is exposed relative to the first casing 11 and the second casing 12, the first appearance surface 300 forms a part of an appearance piece of the casing device 100, when the casing device 100 is in the second closed state, the second appearance surface 400 of the second rotating shaft assembly 3 is exposed relative to the second casing 12 and the third casing 13, and the second appearance surface 400 forms a part of an appearance piece of the electronic device 1000.

As shown in fig. 1C and 3C, the first thickness of the first appearance surface 300 of the first spindle assembly 2 is smaller than the second thickness of the second appearance surface 400 of the second spindle assembly 3, and the second thickness of the second appearance surface 400 is substantially equal to the sum of the dimensions of the first, second, and

third housings

11, 12, and 13 in the thickness direction. Therefore, if the third housing 13 is folded before the first housing 11 is folded, the third housing 13 and the second housing 12 are not supported by the first housing 11, and the second rotary shaft assembly 3 is difficult to support the third housing 13 alone and receives excessive pressure, thereby damaging the second rotary shaft assembly 3. In addition, if the third housing 13 is folded first and then the first housing 11 is folded, the third housing 13 is added between the first housing 11 and the second housing 12, so that the first rotating shaft assembly 2 is subjected to an excessive tensile force and the screen 200 is subjected to an excessive pressure, thereby damaging the first rotating shaft assembly 2 and the screen 200.

Therefore, in the present embodiment, based on the size design of the first spindle assembly 2 and the second spindle assembly 3, when the electronic apparatus 1000 is folded, the order of folding the first housing 11 and folding the third housing 13 is required. Understandably, in some other embodiments, by adjusting the size design of the first rotating shaft assembly 2 and the second rotating shaft assembly 3 or designing the structure of the first rotating shaft assembly 2 and the second rotating shaft assembly 3, when the electronic device 1000 is folded, the third housing 13 may be folded first and then the first housing 11 may be folded, and the first housing 11 and the third housing 13 may also be folded at the same time, which is not limited in this application.

In the present application, the cover 212 may be smaller in size than the back cover 213 to reduce costs. In addition, the cover body 212 and the back cover 213 are designed in a split manner, so that the processing, the assembly and the replacement are convenient. In other embodiments, the cover 212 and the back cover 213 may also be a one-piece structure, which is not limited in this application. It should be understood that in other embodiments, the main shaft 21 may have more housings, and the number, structure, position, etc. of the housings are arranged corresponding to the connecting assembly 24.

The structure of the second transfer shaft 2478 may be the same as that of the first transfer shaft 2477, so as to adopt the same material, reduce the material types of the first transfer shaft assembly 2, and reduce the cost of the first transfer shaft assembly 2. In other embodiments, the structure of the second transfer shaft 2478 may be different from the structure of the first transfer shaft 2477, which is not strictly limited in this application.

The structure of the third transfer shaft 2479 may be the same as that of the first transfer shaft 2477, so as to adopt the same material, reduce the material types of the first transfer shaft assembly 2, and reduce the cost of the first transfer shaft assembly 2. In other embodiments, the third shaft 2479 may have a structure different from that of the first shaft 2477, which is not strictly limited in this application.

The number of the third transfer shafts 2479 is the same as that of the synchronizing gears 2473, and the third transfer shafts 2479, the synchronizing gears 2473 and the partial springs 24751 in the elastic member 2475 are arranged in a one-to-one correspondence.

The bottom end of the third transit shaft 2479 can be fixedly connected between the first fixing plates 2474 by welding or bonding.

It is understood that the damping assembly 247 of the present application can have a variety of configurations. For example, in other embodiments, the damping assembly 247 may indirectly define the position of the first swing arm 245 and the position of the second swing arm 246 by defining the position of the synchronizing gear 2473. For example, the first and

second detents

2471, 2472 and the synchronizing gear 2473 form a snap-fit structure therebetween, and the rotating ends 2451, 2461 of the first and

second swing arms

245, 246 and the first and

second detents

2471, 2472 have no snap-fit structure therebetween. In other embodiments, the damping assembly 247 may not have the second detent 2472, and the first swing arm 245 and the second swing arm 246 can be stopped at certain positions by the snap-fit structure between the first detent 2471 and the synchronizing gear 2473, the first swing arm 245 and the second swing arm 246. In other embodiments, the damping assembly 247 can be provided without a fixed plate, and the two ends of the resilient member 2475 can abut against the first detent 2471 and the structure of the main shaft 21, respectively, and the resilient member 2475 can be compressed between the first detent 2471 and the main shaft 21. In other embodiments, the damping assembly 247 can be provided without the synchronizing gear 2473 and the third transfer shaft 2479, and the rotating end 2451 of the first swing arm 245 can directly mesh with the rotating end 2461 of the second swing arm 246. While the above embodiment is an exemplary structure of the damping assembly 247, the damping assembly 247 may have other implementation structures, which is not strictly limited in this application.

Referring to fig. 15, fig. 15 is a partial structural schematic view of the connecting assembly 24 shown in fig. 8, and the structure of the first swing arm 245 shown in fig. 12A, the structure of the second swing arm 246 shown in fig. 12B, and the structure of the damping assembly 247 shown in fig. 14 are combined.

In the present embodiment, the rotating end 2451 of the first swing arm 245, the rotating end 2461 of the second swing arm 246 and the synchronizing gear 2473 are all engaged with the first detent member 2471 and the second detent member 2472 to form an engaging structure, so that the first swing arm 245 and the second swing arm 246 can stay at certain positions. In addition, because the relative position relationship of the components of the damping assembly 247 is stable, the elastic member 2475 is in a compressed state, and the elastic force generated by the elastic member 2475 drives the first locking member 2471 and the second locking member 2472 to cooperatively press the rotating end 2451 of the first swing arm 245, the synchronizing gear 2473 and the rotating end 2461 of the second swing arm 246, so that the locking structure between the rotating end 2451 of the first swing arm 245, the synchronizing gear 2473 and the rotating end 2461 of the second swing arm 246 and the first locking member 2471 and the second locking member 2472 is stable.

When the rotating end 2451 of the first swing arm 245, the rotating end 2461 of the second swing arm 246 and the synchronizing gear 2473 rotate relative to the first blocking member 2471 and the second blocking member 2472, the relative positions of the first protrusions (2455, 2465, 24733) and the first protrusions 24714 are changed, different clamping structures can be formed, and the relative positions of the second protrusions (2458, 2469, 24734) and the second protrusions 24724 are changed, so that different clamping structures can be formed.

Specifically, when the first swing arm 245 and the second swing arm 246 move relatively, the rotating end 2451 of the first swing arm 245, the synchronizing gear 2473, and the rotating end 2461 of the second swing arm 246 need to be switched from one latching structure to another latching structure between the first latching member 2471 and the second latching member 2472. In the process of switching the clamping structure, the first clamping member 2471 is far away from the second clamping member 2472, the elastic member 2475 is further compressed, and the elastic force generated by the elastic member 2475 forms a motion damping force, so that the first swing arm 245 and the second swing arm 246 can move relative to each other only by a certain driving force. In short, the damping assembly 247 can provide a motion damping force to the relative motion of the first and

second swing arms

245 and 246.

It is understood that, in other embodiments, the first end 2431 of the first connecting arm 243 and/or the first end 2441 of the second connecting arm 244 may also be connected to the main shaft 21 by a solid shaft, which is not limited in this application.

second detents

2471, 2472 of the damping assembly 247 are fixed relative to the main shaft 21. The rotating end 2451 of the first swing arm 245 rotatably connects the first locking member 2471 and the second locking member 2472 via the first rotating shaft 2477, thereby rotatably connecting the main shaft 21.

Referring to fig. 17A to 18B and fig. 20 in combination, fig. 20 is a schematic structural view of the connecting element 24 and the main shaft 21 shown in fig. 8 in a first closed state.

In the present application, two ends (2431, 2432) of the first connecting arm 243 of the connecting assembly 24 are respectively and rotatably connected with the main shaft 21 and the first fixing frame 241, so as to form a connecting rod structure, and the rotating end 2451 of the first swinging arm 245 is rotatably connected with the main shaft 21 and the sliding end 2452 is slidably connected with the first fixing frame 241, so as to form a connecting rod slider structure; two ends (2441, 2442) of the second connecting arm 244 are respectively and rotatably connected with the main shaft 21 and the second fixing frame 242 to form a connecting rod structure, and a rotating end 2461 of the second swing arm 246 is rotatably connected with the main shaft 21 and a sliding end 2462 is slidably connected with the second fixing frame 242 to form a connecting rod slider structure. The first fixing frame 241 is used for connecting the first housing 11, and the second fixing frame 242 is used for connecting the second housing 12, so that the connecting assembly 24 of the first rotating shaft assembly 2 realizes the connection between the first housing 11 and the second housing 12 and the main shaft 21 through the connecting rod structure and the connecting rod slider structure.

As shown in fig. 17A, 18A and 16, when the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are unfolded from the first closed state to the open state through the first rotating shaft assembly 2, the first end 2431 of the first connecting arm 243 rotates into the main shaft 21, the first end 2441 of the second connecting arm 244 rotates into the main shaft 21, the sliding end 2452 of the first swing arm 245 slides into the first fixed frame 241, the sliding end 2462 of the second swing arm 246 slides into the second fixed frame 242, and the distance between the first fixed frame 241 and the second fixed frame 242 and the main shaft 21 is small.

As shown in fig. 17B, 18B and 20, when the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2, the first end 2431 of the first connecting arm 243 partially rotates out of the main shaft 21, the first end 2441 of the second connecting arm 244 partially rotates out of the main shaft 21, the sliding end 2452 of the first swing arm 245 partially slides out of the first fixing frame 241, the sliding end 2462 of the second swing arm 246 partially slides out of the second fixing frame 242, and the distances between the first fixing frame 241 and the main shaft 21 and between the second fixing frame 242 and the main shaft are relatively large. Therefore, the first rotating shaft assembly 2 can draw the first housing 11 and the second housing 12 close to the main shaft 21 by the first fixing frame 241 and the second fixing frame 242 respectively in the process that the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are unfolded from the first closed state to the open state by the first rotating shaft assembly 2, so that the first housing 11 and the second housing 12 are close to the main shaft 21; when the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2, the first housing 11 and the second housing 12 are pushed away through the first fixing frame 241 and the second fixing frame 242, so that the first housing 11 and the second housing 12 are away from the spindle 21, and the structure of the first rotating shaft assembly 2 can better adapt to the deformation structure of the screen 200, so as to reduce the risk of pulling or pressing the screen 200, and improve the reliability of the screen 200 and the electronic device 1000.

When the second housing 12 and the third housing 13 are in an open state, and the first housing 11 and the second housing 12 are relatively folded from the open state to a first closed state through the first rotating shaft assembly 2, the main shaft 21 is away from the first fixed frame 241 and the second fixed frame 242, and the rotating end 2451 of the first swing arm 245 and the rotating end 2461 of the second swing arm 246 are respectively rotatably connected with the main shaft 21 in a fixed shaft manner, so that the sliding end 2452 of the first swing arm 245 and the sliding end 2462 of the second swing arm 246 are respectively away from the first fixed frame 241 and the second fixed frame 242, so that an escape space 2460 can be left between the sliding end 2452 of the first swing arm 245 and the first fixed frame 241, and an escape space 2460 is left between the sliding end 2462 of the second swing arm 246 and the second fixed frame 242 for escaping a part of the connecting device 4, so that the connecting device 4 can move relative to the first rotating shaft assembly 2.

The main movement mechanism of the first rotating shaft assembly 2 is mainly described above, and the first support 22 and the second support 23 of the first rotating shaft assembly 2 move relatively with the movement of the main movement mechanism. The structure of the first support 22, the structure of the second support 23, and the connection structure of the first support 22 and the second support 23 to the connection assembly 24 will be described below with reference to the drawings.

In some embodiments, the first support 22 includes a first support plate 221, a first rotation block 222, a first guide member 223, and a first fitting member 224. The first rotation block 222, the first guide member 223 and the first fitting member 224 are fixed to the first support plate 221. For example, the first support plate 221 may be made of a material having a low density and a certain rigidity, such as a carbon fiber material. The first rotating block 222, the first guiding element 223 and the first fitting element 224 may be formed in an integral structure by a metal injection molding process to have high structural strength.

The first rotating block 222 may include a baffle 2221 and a second arc-shaped arm 2222, wherein one side of the second arc-shaped arm 2222 is connected to the baffle 2221, and the other side is suspended. The baffle 2221 serves to support the second arc arm 2222 to increase the structural strength of the first rotating block 222. The second arc-shaped arm 2222 is fixedly coupled to the first support plate 221.

Wherein the first guide 223 is provided with a guide runner 2231. The opening of the guide chute 2231 is located on the end surface of the first guide member 223, so that the structural member mounted on the guide chute 2231 can be embedded into the guide chute 2231 from the opening of the end surface, and can slide back and forth along the extending direction of the guide chute 2231, thereby performing a limiting function. For example, the guide sliding channel 2231 may extend in an arc shape. Of course, the extending direction of the guide sliding groove 2231 may be designed as one or a combination of more of a curve, a straight line and a broken line.

The first engaging member 224 is inclined relative to the first supporting plate 221 to engage with other structures in an inclined manner for limiting.

It should be understood that the first rotating block 222 is mainly used to provide a rotating connection structure, and the first rotating block 222 may have other implementing structures, which are not limited in this application. The first guiding element 223 mainly provides a guiding sliding groove to guide the moving direction of other structural members, and the first guiding element 223 may not be provided in the present application, or the guiding of the moving direction of the structural member may be implemented by other structures, which is not strictly limited in the present application. The first mating member 224 is primarily to provide a mating structure for mating with other structures, and the first mating member 224 may not be provided or may be mated by other structures, which are not limited in this application.

In some embodiments, the second support 23 includes a second support plate 231, a second rotating block 232, a second guide member 233, and a second fitting member 234. The second rotating block 232, the second guide 233, and the second fitting member 234 are fixed to the second support plate 231. For example, the second support plate 231 may be made of a material having a low density and a certain rigidity, such as a carbon fiber material. The second rotating block 232, the second guiding element 233 and the second mating element 234 may be formed in an integral structure by a metal injection molding process, so as to have high structural strength.

The second rotating block 232 may include a blocking plate 2321 and a second arc-shaped arm 2322, one side of the second arc-shaped arm 2322 is connected to the blocking plate 2321, and the other side is suspended. The blocking plate 2321 serves to support the second arc-shaped arm 2322 to increase the structural strength of the first rotation block 222.

Wherein the second guide 233 is provided with a guide link 2331. The opening of the guide chute 2331 is located on the end surface of the second guide member 233, so that the structural member mounted on the guide chute 2331 can be inserted into the guide chute 2331 from the opening of the end surface and can slide back and forth along the extending direction of the guide chute 2331, thereby performing a limiting function. For example, the guide link 2331 may extend in an arc shape. Of course, the extending direction of the guide link 2331 may be designed to be one or a combination of a curved line, a straight line and a broken line.

The second engaging member 234 is inclined relative to the second supporting plate 231 to engage with other structures in an inclined manner for limiting.

It should be understood that the first rotating block 222 mainly aims to provide a rotating connection structure, and the first rotating block 222 may have other implementing structures, and the structures of the two structures may be the same or different, and the present application is not limited thereto. The second guiding element 233 mainly provides a guiding chute to guide the moving direction of other structural members, and the present application may also guide the moving direction of the structural members through other structures, which is not limited in this application.

Therefore, in the first closed state, the first support 22, the main shaft 21 and the second support 23 of the first rotating shaft assembly 2 together enclose the space 210 of Rong Bing similar to a drop shape. Furthermore, at some positions of the first rotating shaft assembly 2, the structural members of the connecting assembly 24 of the first rotating shaft assembly 2 can also cooperate with the first support 22, the main shaft 21 and the second support 23 to together surround the more complete drop-shaped Rong Bing space 210.

The surface of the first mating member 224 facing the first support 22 is the "medial side" of the first mating member 224.

The second support 23 moves in a direction approaching the second swing arm 246, thereby moving the second fitting member 234 of the second support 23 in the second fitting space 2467.

The following description exemplifies the structure of the connecting device 4, and the connecting structure of the connecting device 4 and the structures of the first spindle assembly 2, the second housing 12, the second spindle assembly 3, and the like.

Referring to fig. 33A and 33B in combination, fig. 33A is a partially exploded schematic view of a partial structure of the electronic device 1000 shown in fig. 2, and fig. 33B is a partially exploded schematic view of fig. 33A.

Illustratively, the connecting device 4 includes a connecting piece 41. The connecting member 41 includes a first end 411 and a second end 412, the first end 411 of the connecting member 41 is adjacent to the first rotating shaft assembly 2, and the second end 412 of the connecting member 41 is adjacent to the second rotating shaft assembly 3. When the second housing 12 and the third housing 13 are in the open state and the first housing 11 and the second housing 12 are in the open state, the connecting member 41 can prevent the second rotary shaft assembly 3 from moving, so that the second rotary shaft assembly 3 is in the locked state, and the second housing 12 and the third housing 13 are prevented from being folded relative to the second rotary shaft assembly 3. In the process that the second shell 12 and the third shell 13 are in the opened state, and the first shell 11 and the second shell 12 are relatively folded from the opened state to the first closed state through the first rotating shaft assembly 2, the second end 412 of the connecting member 41 moves in the direction away from the second rotating shaft assembly 3. When the first and

second housings

11 and 12 are in the first closed state, the second and

third housings

12 and 13 can be folded with respect to the second spindle assembly 3.

In some embodiments, at least one of the connector 41, the first spindle assembly 2, the second spindle assembly 3 or the second housing 12 is provided with a driver 42. In the process that the second shell 12 and the third shell 13 are in the open state, and the first shell 11 and the second shell 12 are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2, the driving member 42 is used for driving the second end 412 of the connecting member 41 to move in the direction away from the second rotating shaft assembly 3, so that the second shell 12 and the third shell 13 can be folded relative to the second rotating shaft assembly 3. When the first housing 11 and the second housing 12 are in the first closed state, the second housing 12 and the third housing 13 can move relative to the second rotary shaft assembly 3. The connecting member 41 controls the movement of the second rotating shaft assembly 3, so that the electronic device 1000 is folded according to a certain sequence, and the first rotating shaft assembly 2 and the second rotating shaft assembly 3 are prevented from being pressed or pulled to damage the structure of the electronic device, so that the first rotating shaft assembly 2 and the second rotating shaft assembly 3 are long in service life and high in reliability.

In some other embodiments, the driving element 42 may also be used to drive the second end 412 of the connecting element 41 to move close to the second rotating shaft assembly 3 during the process of unfolding the first and

second shells

11 and 12 from the first closed state to the open state through the first rotating shaft assembly 2 when the second and

third shells

12 and 13 are in the open state.

In some embodiments, the connector 41 may be slidably coupled to the second housing 12. Illustratively, the second housing 12 is provided with a sliding groove 121, and the sliding groove 121 may extend to end surfaces of the left and right sides of the second housing 12. The connecting member 41 is located in the sliding groove 121 of the second housing 12 and can slide along the sliding groove 121, so as to be slidably connected with the second housing 12 through the sliding groove 121. In other embodiments, the second housing 12 may further have a through hole (not shown), and the two end openings of the through hole may be located on the end surfaces of the left and right sides of the second housing 12, respectively. The connecting member 41 is located in the through hole of the second housing 12 and is slidable along the through hole so as to be slidably connected with respect to the second housing 12 through the through hole. In addition, the connecting member 41 may be slidably connected to the second housing 12 through other structures, which are not limited in this application.

As shown in fig. 36A and 36K, the second end 412 of the connecting member 41 passes through the first fixing frame 341 of the second rotating shaft assembly 3 and is clamped into the spindle 31, so as to prevent the relative movement between the first fixing frame 341 of the second rotating shaft assembly 3 and the spindle 31, and prevent the movement of the second rotating shaft assembly 3, so that the second rotating shaft assembly 3 is in a locked state, and the second housing 12 and the third housing 13 are prevented from being folded relative to the second rotating shaft assembly 3.

In the present embodiment, the first swing arm 345 and the second swing arm 346 are driven by the damping assembly 347 to rotate synchronously relative to the main shaft 31.

The first end 411 of the link 41 moves away from the second housing 12 and into the clearance space 2460.

As shown in fig. 36K and 36M, in the process that the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2, the driving member 42 pushes the connecting member 41 to move away from the second rotating shaft assembly 3, the second end 412 of the connecting member 41 moves along with the first end 411 of the connecting member 41 in the direction away from the second housing 12, and the second end 412 of the connecting member 41 moves away from the second rotating shaft assembly 3.

As shown in fig. 36M, when the first housing 11 and the second housing 12 are in the first closed state, and there is a distance between the second end 412 of the connecting member 41 and the main shaft 31, the first fixing frame 341 of the second rotating shaft assembly 3 can move relative to the main shaft 31, that is, the second housing 12 and the third housing 13 can move relative to the second rotating shaft assembly 3.

To sum up, the second housing 12 and the third housing 13 are in an open state, when the first housing 11 and the second housing 12 are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2, the first swing arm 245 and the second swing arm 246 of the first rotating shaft assembly 2 are folded relative to the main shaft 21, the sliding end 2462 of the second swing arm 246 slides relative to the second fixed frame 242 in a direction away from the second housing 12, an avoidance space 2460 is left between the sliding end 2462 and the second fixed frame 242, and the first end 411 of the connecting member 41 enters the avoidance space 2460. The drive member 42 urges the link member 41 in a direction away from the second spindle assembly 3 and away from the spindle 31.

In contrast to the process that the second housing 12 and the third housing 13 are in the opened state, the first housing 11 and the second housing 12 are relatively folded from the opened state to the first closed state through the first rotating shaft assembly 2, the second housing 12 and the third housing 13 are in the opened state, and during the process that the first housing 11 and the second housing 12 are unfolded from the first closed state to the opened state through the first rotating shaft assembly 2, the first swing arm 245 and the second swing arm 246 of the first rotating shaft assembly 2 are unfolded relative to the main shaft 21, the sliding end 2462 of the second swing arm 246 slides relative to the second fixing frame 242 in a direction close to the second housing 12, contacts and pushes the connecting member 41 to slide in a direction close to the second rotating shaft assembly 3, that is, the second end 412 of the connecting member 41 moves in a direction close to the second rotating shaft assembly 3, so that the second end 412 of the connecting member 41, that is, passes through the first fixing frame 341 of the second rotating shaft assembly 3 and is clamped into the main shaft 31, and the second end 412 of the connecting member 41 is connected between the second housing 12 and the second rotating shaft assembly 3. For example, when the first housing 11 and the second housing 12 are in the first closed state, the sliding end 2462 of the second swing arm 246 may contact the connecting element 41 and may be spaced from the connecting element 41, which is not limited in this application.

For example, as shown in fig. 36J and 36L, the through hole 3415 of the first fixing frame 341 opens toward the receiving groove 122 of the second housing 12. When the first housing 11 and the second housing 12 are in the open state, and the second housing 12 and the third housing 13 are in the open state, the second end 412 of the connecting element 41 passes through the first fixing frame 341 of the second rotating shaft assembly 3 through the through hole 3415 and is inserted into the groove 313, so as to fixedly connect the first fixing frame 341 and the main shaft 31 of the second rotating shaft assembly 3.

In the process that the second shell 12 and the third shell 13 are in the opened state, and the first shell 11 and the second shell 12 are relatively folded from the opened state to the first closed state through the first rotating shaft assembly 2, the second end 412 of the connecting piece 41 moves in the direction away from the groove 313; when the first housing 11 and the second housing 12 are in the first closed state, the second end 412 of the connecting member 41 leaves the groove 313, and the first fixing frame 341 and the main shaft 31 of the second rotating shaft assembly 3 can move relatively.

In contrast, when the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are unfolded from the first closed state to the open state, the second end 412 of the connecting element 41 moves in a direction close to the groove 313, and the second end 412 of the connecting element 41 can be inserted into the through hole 3415 of the first fixing frame 341 from the receiving groove 122 of the second housing 12 and inserted into the groove 313 of the spindle 31 through the through hole 3415 of the first fixing frame 341, so as to prevent the second spindle assembly 3 from moving and prevent the second housing 12 and the third housing 13 from being folded relative to the second spindle assembly 3.

Illustratively, as shown in fig. 36D, 36E and 36L, one side of the relief notch 235 of the second support member 23 extends to an end surface of the second support member 23 facing the second housing 12 to provide a relief space when the first end 411 of the connecting member 41 moves away from the second housing 12. When the first housing 11 and the second housing 12 are in the first closed state, the avoidance gap 235 may communicate with the avoidance space 2460 between the two second sliding grooves 2423 of the second fixing frame 242 to enlarge the avoidance space 2460 so as to avoid the first end 411 of the connecting member 41.

Illustratively, the first rotating shaft assembly 2 includes a first moving member 20, the second rotating shaft assembly 3 includes a second moving member 30, and the first end 411 of the connecting device 4 is connected to the first moving member 20 of the first rotating shaft assembly 2.

Referring to fig. 33D and 34B, when the first housing 11 and the second housing 12 are in the open state and the second housing 12 and the third housing 13 are in the open state, the second end 412 of the connecting member 41 is connected between the second housing 12 and the second moving element 30 of the second rotating shaft assembly 3, so as to prevent the second housing 12 and the third housing 13 from being folded relative to the second rotating shaft assembly 3. In the process that the second shell 12 and the third shell 13 are in the open state, and the first shell 11 and the second shell 12 are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2, the first moving member 20 of the first rotating shaft assembly 2 moves away from the second shell 12, and an avoidance space 2460 is formed between the first moving member 20 and the second shell 12; the first end 411 of the connecting member 41 enters the escape space 2460, and the second end 412 of the connecting member 41 moves in a direction away from the second moving member 30 of the second rotating shaft assembly 3, so that the second housing 12 and the third housing 13 can be folded with respect to the second rotating shaft assembly 3.

Conversely, in the process that the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are unfolded from the first closed state to the open state through the first rotating shaft assembly 2, the first moving member 20 of the first rotating shaft assembly 2 moves in a direction approaching the second housing 12 and pushes the first end 411 of the connecting member 41 to move away from the first rotating shaft assembly 2, and the second end 412 of the connecting member 41 moves in a direction approaching the second moving member 30 of the second rotating shaft assembly 3.

Referring to fig. 33D, fig. 34B, fig. 36J and fig. 36L, in the present embodiment, the first moving element 20 of the first rotating shaft assembly 2 may include a second swing arm 246.

When the first and

second housings

11 and 12 are in the open state, the first end 411 of the connecting member 41 is close to the sliding end 2462 of the second swing arm 246 of the first rotation shaft assembly 2.

In the process that the second housing 12 and the third housing 13 are in the opened state, and the first housing 11 and the second housing 12 are relatively folded from the opened state to the first closed state through the first rotating shaft assembly 2, the first swing arm 245 and the second swing arm 246 of the first rotating shaft assembly 2 are relatively folded, the sliding end 2462 of the second swing arm 246 of the first rotating shaft assembly 2 moves away from the second housing 12, and an escape space 2460 is formed between the sliding end 2462 of the second swing arm 246 and the second housing 12, so that the first end 411 of the connecting member 41 can move away from the second housing 12.

Conversely, during the process of unfolding the first and

second housings

third housings

12 and 13 are in the open state, the first and

second swing arms

245 and 246 of the first rotating shaft assembly 2 are unfolded relatively, and the sliding end 2462 of the second swing arm 246 of the first rotating shaft assembly 2 moves toward the second housing 12 and pushes the first end 411 of the connecting member 41 to move away from the first rotating shaft assembly 2.

As shown in fig. 33D and 34B, in other embodiments, the second swing arm 246 may have other structures, for example, a connection structure may be provided between the second swing arm 246 and the first swing arm 245, so that the second swing arm 246 can move with the first swing arm 245 relative to the second housing 12 (the second housing 12). In still other embodiments, the first moving element 20 may include one or more structures of the main shaft 21, the first swing arm 245, the first fixing frame 241, and the first housing 11, which is not limited in this application. When the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2, the main shaft 21, the first swing arm 245, the first fixing frame 241, the first housing 11, and the like can move in a direction away from the second housing 12.

Please refer to fig. 33D, fig. 34B, fig. 36K and fig. 36M in combination. The first fixing frame 341 is fixedly connected to the second housing 12, and the second fixing frame 342 is fixedly connected to the third housing 13. In the present embodiment, the second mover 30 of the second spindle assembly 3 may include a main shaft 31. When the first housing 11 and the second housing 12 are in an open state, and the second housing 12 and the third housing 13 are in an open state, the first fixing frame 341 and the second fixing frame 342 of the second rotating shaft assembly 3 are relatively unfolded, and the first fixing frame 341 and the main shaft 31 of the second rotating shaft assembly 3 are fixedly connected through the second end 412 of the connecting member 41.

During the process that the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are relatively folded from the open state to the first closed state, the second end 412 of the connecting member 41 moves in a direction away from the main shaft 31 of the second rotating shaft assembly 3. When the first housing 11 and the second housing 12 are in the first closed state, the first fixing frame 341 and the spindle 31 of the second spindle assembly 3 can move relatively.

In contrast, in the process that the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are unfolded from the first closed state to the open state, the second end 412 of the connecting member 41 moves in a direction close to the spindle 31 of the second spindle assembly 3, so that the second end 412 of the connecting member 41 fixedly connects the first fixing frame 341 and the spindle 31 of the second spindle assembly 3.

As shown in fig. 33D and 34B, in other embodiments, the second mover 30 may further include a first swing arm 345; in this embodiment, when the first housing 11 and the second housing 12 are in the open state, and the second housing 12 and the third housing 13 are in the open state, the second end 412 of the connecting member 41 may also be snapped into the first swing arm 345 to prevent the first swing arm 345 from sliding relative to the first fixing frame 341, so as to prevent the second housing 12 and the third housing 13 from folding relative to the second spindle assembly 3. In still other embodiments, the second mover 30 of the second rotary shaft assembly 3 may also include other structures. In the process that the first housing 11 and the second housing 12 are in the first closed state, and the second housing 12 and the third housing 13 are relatively folded from the open state to the second closed state through the second rotating shaft assembly 3, other structures can move relative to the second housing 12 (the second housing 12), which is not limited in this application.

For example, the connecting member 41 may further include a limiting member (not shown) for limiting a moving distance of the connecting member 41 relative to the second rotating shaft assembly 3, and the structure of the limiting member is not limited in this application.

In the present application, the driving member 42 may have various implementations, and the structure of the driving member 42 is exemplified below.

Referring to fig. 37 and 38 in combination, fig. 37 is an exploded view of the connecting device 4 shown in fig. 33A in the first embodiment, and fig. 38 is a view of the housing device 100 shown in fig. 2 in the first embodiment. In the first embodiment, the structures of the first casing 11a, the first rotating shaft assembly 2a, the second casing 12a, the second rotating shaft assembly 3a, the third casing 13a and the connecting member 41a of the casing device 100a of the electronic apparatus 1000a and the connecting structures between the components can refer to the structures of the first casing 11, the first rotating shaft assembly 2, the second casing 12, the second rotating shaft assembly 3, the third casing 13 and the connecting member 41 and the connecting structures between the components in the electronic apparatus 1000 shown in fig. 36A to 36M, and the description thereof is omitted.

Only the structure of the driver 42a, the connection structure between the driver 42a and another structure, and the difference between the connectors 41a will be described below.

In the first embodiment, the connecting member 41a may be provided with the position-restricting flange 413a, and the outer diameter of the position-restricting flange 413a is larger than the outer diameter of the main body portion of the connecting member 41a. For example, the driving element 42a may be sleeved on the connecting element 41a and located at a side of the position-limiting flange 413a close to the second end 412a of the connecting element 41a, the driving element 42a may be located between the position-limiting flange 413a and the second end 412a of the connecting element 41a, and the driving element 42a may move relative to the connecting element 41a under the pushing of the position-limiting flange 413 a. In other embodiments, the driving member 42a can be located on the side of the position-limiting flange 413a near the first end 411a, and the driving member 42a can be located between the position-limiting flange 413a and the first end 411a of the connecting member 41a.

Illustratively, the second housing 12a may further be provided with a receiving groove 122a, and the receiving groove 122a communicates with the sliding groove 121 a. The position-limiting flange 413a may be mounted to the receiving groove 122a. One end of the driving member 42a may be connected to the position-limiting flange 413a and the other end may be connected to a groove wall of the receiving groove 122a. The receiving groove 122a may be located at an end portion of the second housing 12a close to the second rotary shaft assembly 3a, or may be located at a middle portion of the second housing 12a.

Illustratively, the driving member 42a may be an elastic member, such as a spring, which is elastically deformable. A driving member 42a (elastic member) is disposed at the second end of the connecting member 41a, one end of the driving member 42a abuts against the connecting member 41a, and the other end of the driving member 42a abuts against the second rotating shaft assembly 3a.

Referring to fig. 39A to 39D, fig. 39A is a schematic diagram of a portion of the cross-sectional structure of fig. 38 taken along the line C1-C1 in the first embodiment, fig. 39B is a schematic diagram of another portion of the cross-sectional structure of fig. 38 taken along the line C1-C1 in the first embodiment, fig. 39C is a schematic diagram of the structure of fig. 39A in the first closed state, and fig. 39D is a schematic diagram of the structure of fig. 39B in the first closed state. The cross-sectional structure of fig. 39A passes through the first housing 11a, the first spindle assembly 2a, the second housing 12a, and the connecting device 4a, and the cross-sectional structure of fig. 39B passes through the second housing 12a, the second spindle assembly 3a, the third housing 13a, and the connecting device 4a.

When the second housing 12a and the third housing 13a are in the open state and the first housing 11a and the second housing 12a are in the open state, as shown in fig. 38 and 39B, the limit flange 413a of the connecting member 41a presses the driving member 42a, two ends of the driving member 42a respectively abut against the limit flange 413a of the connecting member 41a and the first fixing frame 341a of the second rotating shaft assembly 3a, the driving member 42a is in the compressed state, and the second end 412a of the connecting member 41a passes through the first fixing frame 341a of the second rotating shaft assembly 3a and is clamped into the spindle 31a, so as to prevent the second housing 12a and the third housing 13a from being folded relative to the second rotating shaft assembly 3a.

As shown in fig. 39D, in the process that the second housing 12a and the third housing 13a are in the open state, and the first housing 11a and the second housing 12a are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2a, the driving member 42a changes from the compressed state to the extended state, generating a pushing force, and the limit flange 413a moves towards the direction close to the first rotating shaft assembly 2a under the action of the pushing force, so that the connecting member 41a moves away from the second rotating shaft assembly 3a and away from the main shaft 31a under the action of the pushing force. The second end 412a of the link 41a is away from the main shaft 31a. Understandably, the driving member 42a is considered to be in the extended state when the driving member 42a is not elastically deformed or is slightly elastically deformed. The driving member 42a in the extended state is compressed, that is, the compressed state of the driving member 42a is elastically deformed relative to the extended state, or the amount of elastic deformation of the driving member 42a in the compressed state is greater than the amount of elastic deformation of the driving member 42a in the extended state.

In contrast, when the second housing 12a and the third housing 13a are in the open state, and the first housing 11a and the second housing 12a are expanded from the first closed state to the open state through the first rotating shaft assembly 2a, the sliding end 2462a of the second swing arm 246a slides relative to the second fixed frame 242a in a direction approaching the second housing 12a, contacts and pushes the connecting member 41a to slide in a direction approaching the second rotating shaft assembly 3a, and the limit flange 413a of the connecting member 41a presses the driving member 42a to place the driving member 42a in the compressed state.

Referring to fig. 40, fig. 40 is a schematic diagram of the structure of fig. 39C in another embodiment.

Illustratively, the second swing arm 246a can be provided with a bump 2453a, the bump 2453a can be fixed to the sliding end 2462a, and the cross-sectional area of the bump 2453a can be larger than the cross-sectional area of the sliding end 2462a to increase the contact area between the second swing arm 246a and the connecting member 41a, so that the sliding end 2462a of the second swing arm 246a can push the connecting member 41a. Understandably, a section of the structure of the second swing arm 246a in a direction perpendicular to the extending direction of the second swing arm 246a is a cross section of the structure of the second swing arm 246 a.

In still other embodiments, the driving member 42a may further include a first magnetic member (not shown) and a second magnetic member (not shown). The first and second magnetic members are fixed to the sliding end 2462a of the second swing arm 246a and the first end 411a of the link member 41a, respectively. In this embodiment, there may be an attractive force between the first magnetic member and the second magnetic member, that is, the magnetic poles of the first magnetic member near one end of the second magnetic member and the magnetic poles of the second magnetic member near one end of the first magnetic member have opposite polarities, for example, the end of the first magnetic member near the second magnetic member is an N pole, and the end of the second magnetic member near the first magnetic member 421a is an S pole. Understandably, a magnetic element, which may also be referred to as a magnet, refers to a substance or material capable of generating a magnetic field. The magnetic member may include a permanent magnet and a soft magnet. Wherein, the permanent magnet can keep magnetism for a long time, is difficult for losing magnetism, also is difficult for magnetizing, for example: the permanent magnet may include an alloy permanent magnet material, a ferrite permanent magnet material, and the like. The alloy permanent magnet material may include neodymium iron boron (Nd 2Fe 14B), samarium cobalt (SmCo), aluminum nickel cobalt (AlNiCo), and other alloys. The polarity of soft magnets varies with the polarity of the applied magnetic field and can be used as both magnetizers and electromagnets, for example: the soft-magnetic body may comprise iron-silicon alloys (silicon steel sheets), soft-magnetic ferrite materials, iron, cobalt, nickel, alloys of iron, cobalt, nickel, etc. In the present application, the first magnetic member and the second magnetic member may both adopt permanent magnets; one of the first magnetic member and the second magnetic member may be a permanent magnet capable of maintaining magnetism for a long time, and the other may be a soft magnet capable of being magnetized by the permanent magnet, which is not limited in the present application.

In still other embodiments, the driving member 42a may further include a first magnetic member and a second magnetic member. The first magnetic member may be fixed to the first fixing frame 341a of the second rotary shaft assembly 3a and/or the main shaft 31a of the second rotary shaft assembly 3a, and the second magnetic member may be fixed to the second end 412a of the connecting member 41a. In this embodiment, a repulsive force may also exist between the first magnetic member and the second magnetic member, that is, the polarities of the magnetic pole of the end of the first magnetic member close to the second magnetic member and the magnetic pole of the end of the second magnetic member close to the first magnetic member are the same, for example, the end of the first magnetic member close to the second magnetic member is an N pole, and the end of the second magnetic member close to the first magnetic member 421a is also an N pole.

In still other embodiments, the driving member 42a may further include a first magnetic member, a second magnetic member, a third magnetic member (not shown), and a fourth magnetic member (not shown). Wherein, the first magnetic member and the second magnetic member may be fixed to the sliding end 2462a of the second swing arm 246a and the first end 411a of the connecting member 41a, respectively. The third magnetic member may be fixed to the first fixing frame 341a of the second rotary shaft assembly 3a and/or the main shaft 31a of the second rotary shaft assembly 3a, and the fourth magnetic member may be fixed to the second end 412a of the connecting member 41a. In the present embodiment, there may be an attractive force between the first magnetic member and the second magnetic member, and a repulsive force between the third magnetic member and the fourth magnetic member. In the application, the third magnetic part and the fourth magnetic part may both adopt permanent magnets; one of the third magnetic member and the fourth magnetic member may be a permanent magnet, and the other may be a soft magnet, which is not limited in the present application.

Referring to fig. 41 and fig. 42A to fig. 42C in combination, fig. 41 is a schematic structural view of the connecting device 4 shown in fig. 33A in the second embodiment, fig. 42A is a schematic structural view of the housing device 100 shown in fig. 2 in the second embodiment, fig. 42B is a schematic structural view of a part of the housing device 100 shown in fig. 42A, and fig. 42C is a schematic structural view of a part of the structure shown in fig. 42B in the first closed state. Fig. 42C illustrates the structure of the first swing arm 245b, the damping assembly 247b, the second swing arm 246b, the second fixing frame 242b, the connecting member 41b and the driving member 42 b.

Only the structure of the driver 42b, the connection structure of the driver 42b and other structures, and the difference of the connector 41b will be described below.

In the second embodiment, the driving member 42b may include a first magnetic member 421b and a second magnetic member 422b. The first and second

magnetic members

421b and 422b are fixed to the sliding end 2462b of the second swing arm 246b and the first end 411b of the connecting member 41b, respectively. In this embodiment, there may be an attractive force between the first magnetic member 421b and the second magnetic member 422b, that is, the polarities of the magnetic poles on the opposite sides of the first magnetic member 421b and the second magnetic member 422b are opposite, for example, if the end of the first magnetic member 421b close to the second magnetic member 422b is an N pole, the end of the second magnetic member 422b close to the first magnetic member 421b is an S pole.

Illustratively, the driving member 42b may also be an elastic member (not shown), and in this embodiment, the driving member 42b is connected between the sliding end 2462b of the second swing arm 246b of the first rotating shaft assembly 2b and the first end 411b of the connecting member 41 b.

In other embodiments, the first magnetic member 421b may be fixed to the first fixing frame 341b of the second rotating shaft assembly 3b and/or the main shaft 31b of the second rotating shaft assembly 3b, and the second magnetic member 422b may be fixed to the second end 412b of the connecting member 41 b. In this embodiment, there may be a repulsive force between the first magnetic member 421b and the second magnetic member 422b, that is, the polarities of the magnetic poles of the first magnetic member 421b and the second magnetic member 422b on the opposite side and the magnetic poles of the second magnetic member 422b and the first magnetic member 421b on the opposite side are the same.

In still other embodiments, the driving member 42b may further include a first magnetic member 421b, a second magnetic member 422b, a third magnetic member (not shown), and a fourth magnetic member (not shown). Wherein, the first magnetic member 421b and the second magnetic member 422b can be fixed at the sliding end 2462b of the second swing arm 246b and the first end 411b of the connecting member 41b, respectively. The third magnetic member may be fixed to the first fixing frame 341b of the second rotary shaft assembly 3b and/or the main shaft 31b of the second rotary shaft assembly 3b, and the fourth magnetic member may be fixed to the second end 412b of the connecting member 41 b. In the present embodiment, there may be an attractive force between the first magnetic member 421b and the second magnetic member 422b, and a repulsive force between the third magnetic member and the fourth magnetic member.

In some embodiments, the receiving groove 122c has a first side wall perpendicular to the extending direction of the connecting member 41c, and the first side wall is close to the first rotating shaft assembly 2c. The third magnetic element 423c can be fixed to the receiving groove 122c near the first sidewall of the first rotating shaft assembly 2c and movably sleeved on the connecting element 41c, and the fourth magnetic element 424c is fixedly sleeved on the connecting element 41c and located in the receiving groove 122c.

In other embodiments, the receiving groove 122c has a second sidewall perpendicular to the extending direction of the connecting member 41c, and the second sidewall is close to the second rotary shaft assembly 3c. The third magnetic element 423c can be fixed to the second sidewall of the receiving groove 122c, and the fourth magnetic element 424c is fixedly sleeved on the connecting element 41c and located in the receiving groove 122c.

Referring to fig. 45 and 46C to 46D in combination, fig. 46A is a schematic diagram of a portion of the cross-sectional structure of the structure shown in fig. 45 taken along the line C3-C3 in the third embodiment, fig. 46B is a schematic diagram of another portion of the cross-sectional structure of the structure shown in fig. 45 taken along the line C3-C3 in the third embodiment, fig. 46C is a schematic diagram of the structure shown in fig. 46A in the first closed state, and fig. 46D is a schematic diagram of the structure shown in fig. 46B in the first closed state.

As shown in fig. 46A and 46B, when the second housing 12 and the third housing 13 are in the open state, and the first housing 11 and the second housing 12 are in the open state, the first end 411c of the connecting piece 41c abuts against the sliding end 2462c of the second swing arm 246c of the first rotating shaft assembly 2c, the fourth magnetic piece 424c is located on the side of the third magnetic piece 423c close to the second rotating shaft assembly 3, and there is a gap therebetween, and the second end 412c of the connecting piece 41c passes through the first fixing frame 341c of the second rotating shaft assembly 3c and is clamped into the main shaft 31c, so as to prevent the second housing 12c and the third housing 13c from being folded relative to the second rotating shaft assembly 3c.

As shown in fig. 46C and 46D, in the process that the second housing 12C and the third housing 13C are in the open state, and the first housing 11C and the second housing 12C are relatively folded from the open state to the first closed state through the first rotating shaft assembly 2C, the sliding end 2462C of the second swing arm 246C slides relative to the second fixed frame 242C in a direction away from the second housing 12C, and an escape space 2460C is left between the sliding end 2462C and the second fixed frame 242C. An attractive force exists between the third magnetic member 423c and the fourth magnetic member 424c, and the fourth magnetic member 424c moves toward the third magnetic member 423c under the attractive force, and drives the connecting member 41c to move toward the first rotating shaft assembly 2c, such that the first end 411c of the connecting member 41c enters the avoiding space 2460c and the second end 412c of the connecting member 41c leaves the main shaft 31c. Further, the distance between the third magnetic member 423c and the fourth magnetic member 424c becomes smaller, or the third magnetic member 423c contacts the fourth magnetic member 424c.

When the first and

second housings

11c and 12c are in the first closed state, the first fixing frame 341c of the second rotary shaft assembly 3c can move relative to the main shaft 31c, that is, the second and

third housings

When the second housing 12c and the third housing 13c are in the open state and the first housing 11c and the second housing 12c are in the open state, the third magnetic member 423c and the fourth magnetic member 424c are in contact with each other or have a gap therebetween; when the second housing 12c and the third housing 13c are in the open state, and the first housing 11c and the second housing 12c are folded relatively to the first closed state from the open state through the first rotating shaft assembly 2c, the fourth magnetic member 424c is away from the third magnetic member 423c under the action of the repulsive force, and drives the connecting member 41c to move toward the direction close to the first rotating shaft assembly 2c, so as to drive the second end 412c of the connecting member 41c to move toward the direction away from the second rotating shaft assembly 3c.
