As shown in fig. 7, the first branch housing 102 is rotatably coupled to one side of the main housing 101 by a first rotating shaft assembly 104. Specifically, the first branch housing 102 is at least partially disposed between the first side plate 111 and the second side plate 112. One end of the first branch housing 102 includes a third side plate 121, a fourth side plate 122 and a second arc-shaped portion 123 disposed between the third side plate 121 and the fourth side plate 122.

In this embodiment, when the first branch housing 102 rotates relative to the main housing 101, the third side plate 121 slides on the first side plate 111, the fourth side plate 122 slides on the second side plate 112, and the second arc portion 123 slides on the first arc portion 113, so that the friction force at the contact area between the first branch housing 102 and the main housing 101 can increase the damping effect during the rotation, and meanwhile, the stability during the rotation can be improved, and the first branch housing 102 and the main housing 101 are prevented from being loose. In addition, the third side plate 121 and the fourth side plate 122 are sleeved on the first rotating shaft assembly 104, and the first branch housing 102 is rotatably connected to the main housing 101 through the first rotating shaft assembly 104. The first branch housing 102 and the first rotating shaft assembly 104 may be fixedly connected or rotatably connected. First spindle assembly 104 rotates to rotate first branch housing 102. In one embodiment, the third side plate 121 is engaged with one end of the first rotating shaft assembly 104, and the fourth side plate 122 is engaged with the other end of the first rotating shaft assembly 104, so that the first branch housing 102 is fixedly connected to the first rotating shaft assembly 104, and the first branch housing 102 rotates along with the first rotating shaft assembly 104 when the first rotating shaft assembly 104 rotates. In one embodiment, the first branch housing 102 is in an open state with respect to the main housing 101, meaning that the first branch housing 102 is rotated to be coplanar with the main housing 101. The first branch housing 102 is in a closed state with respect to the main housing 101, which means that an included angle between the first branch housing 102 and the main housing 101 is 70 ° to 110 °.

Referring to fig. 6 and 7, a third through hole 123 is formed on the third side plate 121, and a fourth through hole 124 is formed on the fourth side plate 122. The third through hole 123 and the fourth through hole 124 are disposed opposite to each other in the axial direction of the first spindle assembly 104. One end of the first rotating shaft assembly 104 contacts with a hole wall of the third through hole 123, the other end of the first rotating shaft assembly 104 contacts with a hole wall of the fourth through hole 124, and the first rotating shaft assembly 104 penetrates through the third through hole 123 and the fourth through hole 124 and then is connected with the main housing 101, so that one end of the first branch housing 102 is rotatably connected between the first side plate 111 and the second side plate 112 of the main housing 101.

As shown in fig. 7, the first rotating shaft assembly 104 includes a shaft core 141 and a shaft sleeve 142 sleeved outside the shaft core 141. The inner surface of the sleeve 142 may contact the outer peripheral surface of the core 141, or may have a gap. In one embodiment, a receiving space 140 is formed between the inner surface of the sleeve 142 and the outer circumferential surface of the core 141. The first connector 161 abuts against one end of the shaft core 141, and the second connector 162 is inserted into the inner cavity of the shaft core 141. The shaft core 141 is fixedly connected to the main casing 101 by a first connector 161 and a second connector 162. One end of the shaft sleeve 142 is rotatably connected to the shaft core 141, and the other end of the shaft sleeve 142 is fixedly connected to the third side plate 121 and the fourth side plate 122 of the first branch housing 102, so that when the shaft sleeve 142 rotates relative to the shaft core 141, the first branch housing 102 is driven to rotate relative to the main housing 101.

Further, as shown in fig. 7, the first rotating shaft assembly 104 further includes a driving mechanism 107 disposed in the receiving space 140, and the driving mechanism 107 is configured to drive the sleeve 142 to rotate. For example, the driving mechanism 107 may be a motor, a magnetic member, or the like.

In one embodiment, the driving mechanism 107 is a motor, one end of the driving mechanism 107 is fixed in the accommodating space 140, and the other end of the driving mechanism 107 is provided with a rotating shaft (not shown), the rotating shaft is connected with the shaft sleeve 142, and when the rotating shaft rotates, the shaft sleeve 142 is driven to rotate, so that the rotation of the shaft sleeve 142 is controlled to realize the automatic opening and closing of the first branch housing 102 and the main housing 101. A battery may be disposed in the accommodating space 140, and the battery is connected to the motor to supply power to the motor.

In another embodiment, the driving mechanism 107 includes a transmission assembly 171 and an elastic member 172. The transmission assembly 171 and the elastic member 172 are accommodated in the accommodating space 140. One end of the driving member 171 is connected to the inner surface of the sleeve 142, so that the sleeve 142 is rotated when the driving member 171 rotates. For example, the transmission assembly 171 is engaged with the inner surface of the sleeve 142 by a spline engagement. The elastic member 172 is connected between the driving assembly 171 and the inner surface of the bushing 142. The transmission assembly 171 is used for transmitting the force between the sleeve 142 and the elastic member 172.

When an external force acts on the first branch housing 102, the shaft sleeve 142 rotates under the external force and drives the transmission assembly 171 to rotate, the transmission assembly 171 compresses or stretches the elastic member 172 when rotating, so that the elastic member 172 deforms, at this time, the first branch housing 102 rotates from the first state to the second state relative to the main housing 101, and the elastic member 172 stores energy. When the external force is removed, the shaft sleeve 142 stops rotating, the compression force or the tensile force of the transmission assembly 171 acting on the elastic member 172 disappears, the elastic member 172 gradually recovers to the original shape, the transmission assembly 171 is driven to rotate, and the shaft sleeve 142 is driven to rotate again when the transmission assembly 171 rotates, so that the first branch housing 102 rotates to the third state from the second state relative to the main housing 101. In one embodiment, the first state is a state in which the first branch housing 102 is opened with respect to the main housing 101. The second state is a state in which the first branch case 102 is rotated by an angle of 45 ° with respect to the main case 101 from the open state. The third state is a state when the first branch housing 102 is closed with respect to the main housing 101.

Alternatively, referring to fig. 7 and 8, the driving assembly 171 includes a first driving wheel 173 and a second driving wheel 174. The first transmission wheel 173, the second transmission wheel 174 and the elastic element 172 are all sleeved on the outer peripheral surface of the shaft core 141. The first transmission wheel 173, the second transmission wheel 174 and the elastic member 172 are arranged in order along the axial direction of the shaft core 141. One end of the first driving wheel 173 is fixedly connected to the shaft core 141. The other end of the first driving wheel 173 extends into the first engaging portion 114 and engages with the first engaging portion 114. The first drive wheel 173 is slidably connected to the second drive wheel 174. The peripheral side of the second transmission wheel 174 is connected to the sleeve 142, and the end of the second transmission wheel 174 opposite to the first transmission wheel 173 is connected to the elastic member 172. The elastic member 172 abuts between the second transmission wheel 174 and the inner surface of the sleeve 142. When the sleeve 142 rotates under the external force, the second transmission wheel 174 is driven to rotate, the second transmission wheel 174 gradually moves away from the first transmission wheel 173 when rotating, and presses the elastic member 172 to compress the elastic member 172, and at this time, the first branch housing 102 rotates from the first state to the second state relative to the main housing 101 under the external force. When the external force is removed, the elastic member 172 gradually recovers and moves the second transmission wheel 174 toward the side close to the first transmission wheel 173, the second transmission wheel 174 rotates around the shaft core 141 and drives the shaft sleeve 142 to rotate when moving toward the side close to the first transmission wheel 173, and the shaft sleeve 142 drives the first branch housing 102 to rotate relative to the main housing 101 from the second state to the third state when rotating. In other words, when the first branch housing 102 rotates from the second state to the third state with respect to the main housing 101, the elastic member 172 can drive the first branch housing 102 to automatically rotate, so as to reduce the action of external force and realize the automatic rotation of the first branch housing 102.

In one embodiment, referring to fig. 8 and 9, the first driving wheel 173 is provided with a first protrusion 1730. The second driving wheel 174 is provided with a second protrusion 1740. The first protrusion 1730 includes a first contact surface 173a, a second contact surface 173b, and a third contact surface 173c connected in this order. The second protrusion 1740 includes a first inclined surface 174a and a second inclined surface 174 b. The first inclined surface 174a and the second inclined surface 174b are connected and arranged to be opposite to each other in the circumferential direction of the second transmission wheel 174. The first abutment surface 173a contacts the first inclined surface 174a or the second inclined surface 174 b. Specifically, when the first diverging housing 102 is rotated from the first state to the second state with respect to the main housing 101 by an external force, the first abutment surface 173a comes into contact with the first inclined surface 174a and slides along the first inclined surface 174 a. When the first diverging housing 102 is rotated from the second state to the third state with respect to the main housing 101 by the elastic force, the first abutment surface 173a contacts the second inclined surface 174b and slides along the second inclined surface 174 b.

Further, the second transmission wheel 174 is provided with a third projection 1741 and a fourth projection 1742. The third protrusion 1741 is provided on the side of the first inclined surface 174a facing away from the second inclined surface 174b, and the fourth protrusion 1742 is provided on the side of the second inclined surface 174b facing away from the first inclined surface 174 a. When the first branch housing 102 is in the first state with respect to the main housing 101, the first abutment surface 173a slides to the end of the first inclined surface 174a away from the second inclined surface 174b, and at this time, the second abutment surface 173b abuts on the third protrusion 1741, so that the first branch housing 102 and the main housing 101 are stabilized in the first state. When the first branch housing 102 is in the third state with respect to the main housing 101, the first abutment surface 173a slides to the end of the second inclined surface 174b away from the first inclined surface 174a, and the third abutment surface 173c abuts against the fourth protrusion 1742, so that the first branch housing 102 and the main housing 101 are stabilized in the third state. In other words, the third protrusion 1741 and the fourth protrusion 1742 have a limiting function when the first branch housing 102 rotates relative to the main housing 101, so as to avoid the first branch housing 102 from being bent excessively or reversely.

In one embodiment, the assembly process of the foldable device 100 is: the shaft core 141 passes through the shaft sleeve 142, so that the shaft core 141 is rotatably connected with the shaft sleeve 142, and an accommodating space 140 is formed between the outer peripheral surface of the shaft core 141 and the inner surface of the shaft sleeve 142; the elastic member 172 and the second transmission wheel 174 are sequentially installed, so that one end of the elastic member 172 abuts against the inner surface of the sleeve 142, the second transmission wheel 174 abuts against the other end opposite to the elastic member 172, or the elastic member 172 and the second transmission wheel 174 are fixedly connected and then installed in the accommodating space 140; the first driving wheel 173 is installed such that one end of the first driving wheel 173 is engaged with the second driving wheel 174 and the other end of the first driving wheel 173 is fixedly coupled to the shaft core 141, thereby completing the assembly of the first rotating shaft assembly 104. The assembled first rotating shaft assembly 104 passes through the third through hole 123 and the fourth through hole 124 on the first branch housing 102, so that the first rotating shaft assembly 104 is limited on the first branch housing 102, and two opposite ends of the first rotating shaft assembly 104 are flush with the third side plate 121 and the fourth side plate 122 respectively; the main housing 101 is mounted, such that the first side plate 111 of the main housing 101 contacts the third side plate 121, the second side plate 112 contacts the fourth side plate 122, the first engaging portion 114 is aligned with the third through hole 123, the first through hole 116 is aligned with the fourth through hole 124, the first rotating shaft assembly 104 is pushed by the side of the second side plate 112 away from the first side plate 111, and the second driving wheel 174 in the first rotating shaft assembly 104 is engaged with the first engaging portion 114. The second connecting member 162 is installed on a side of the first side plate 111 away from the second side plate 112, the first connecting member 161 is installed on a side of the second side plate 112 away from the first side plate 111, and the second connecting member 162 is rotated to match the second connecting member 162 with the first connecting member 161, thereby completing the assembly of the foldable device 100.

The foregoing is a partial description of the present application, and it should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present application, and these modifications and decorations are also regarded as the protection scope of the present application.
