For example, the first housing 201 can be provided with a keyboard, a screen, and a touch area (not shown). The rotating shaft 100 is connected between the first housing 201 and the second housing so that the second housing can be opened and closed relative to the first housing 201 . The rotating shaft 100 includes a base 1 , a rotating member 2 , a sliding member 3 , an auxiliary member 4 , a lifting support member 5 , and a connecting rod group 6 .

Referring to FIGS. 1 to 4 , the base 1 is suitable for being arranged on the first housing 201. The base 1 includes a first base body 11 for being arranged on the rear side of the first housing 201, a second base body 12 arranged on the front side of the first base body 11 in a front-to-back direction D1 (arrow facing forward, reverse direction is rear), a rotation shaft 13 arranged on the rear side of the first base body 11 in the front-to-back direction D1 and extending along a left-to-right direction D2 (arrow facing right, reverse direction is left), and a first connecting portion 14 arranged on the first base body 11. The first base body 11 has a guide column 111 extending along the left-to-right direction D2. The second base body 12 has a guide hole 121 extending along an up-down direction D3 (arrow facing upward, reverse direction is downward). The first connecting portion 14 is a fixing member (such as a bolt or a rivet, etc.) in this embodiment.

Referring to Figures 2 to 5, the rotating member 2 is provided on the rotating axis column 13 of the base 1 and is suitable for disposing the second housing. The rotating member 2 can rotate parallel to the left and right directions relative to the base 1. A rotation axis A in direction D2 rotates between a first position (see Figure 2) and a second position (see Figure 11). The rotating member 2 is in the first position and the second position relative to the base 1. During the rotation between positions, it also passes through a transition position (see FIG. 9 ), and the rotation axis A is the axis center of the rotation axis column 13 . The rotating member 2 has a rotating sleeve 21 rotatably sleeved on the rotating shaft 13 , an arc convex surface 22 located on the rotating sleeve 21 , and a groove structure formed on the rotating sleeve 21 The arc convex surface 22 extends obliquely around the rotation axis A, and a first guide portion 23 extends from the rotation sleeve 21 and is used for installing the second housing. The first guide part 23 has a guide section 231 extending obliquely around the rotation axis A, and a maintaining section 232 extending straightly around the rotation axis A.

Referring to Figures 2, 4, 6 and 7, the sliding member 3 is provided on the guide post 111 of the base 1, and can move in the left-right direction D2 relative to the guide post 111 of the base 1. To slide between a third position (see Figure 2) and a fourth position (see Figure 9), the sliding member 3 has a sliding sleeve 31 slidably sleeved on the guide post 111 along the left and right direction D2. An arc concave surface 32 is located at the rear side of the sliding sleeve 31 and matches the arc convex surface 22. It is formed on the arc concave surface 32 in the form of a convex block and can be slidably connected to the first guide portion 23. A first sliding part 33 of the first guide part 23, a second guide part 34 formed in a groove structure on the front side of the sliding sleeve 31 and extending along the up-down direction D3, and a second guide part 34 provided on the sliding sleeve 31 a second connecting portion 35. In this embodiment, the second connecting part 35 is a fixing part (such as a bolt or a rivet, etc.).

Referring to Figures 2 and 4, the auxiliary component 4 is connected between the second connecting portion 35 of the sliding component 3 and the first connecting portion 14 of the base 1, and is provided to prevent the sliding component 3 from moving towards the third Position sliding resistance. In this embodiment, the auxiliary member 4 is a spring, and the elastic force of the spring generates resistance that prevents the sliding member 3 from sliding toward the third position. However, in other embodiments, the auxiliary member 4 may also be a clamp, for example. A friction plate is connected between the sliding member 3 and the base 1 and can generate friction force to generate resistance to prevent the sliding member 3 from sliding toward the third position through friction force. This embodiment is not considered as limit. When the sliding member 3 is in the third position, it is further away from the first connecting portion 14 than when it is in the fourth position. When the sliding member 3 slides toward the third position, the auxiliary member 4 is stretched and elastically deformed. Provide resistance to prevent the slider 3 from sliding toward the third position.

Referring to Figure 1, Figure 2, Figure 4 and Figure 6, the lifting support 5 is provided in the guide hole 121 of the base 1, and can be in an initial position relative to the base 1 along the up and down direction D3 (see It moves in a sliding manner between Figure 2) and a raised position (see Figure 9) located below the initial position. The lifting support member 5 has a sliding column 51 slidably inserted into the guide hole 121 along the up-down direction D3, and a setting portion 52 connected to the bottom of the sliding column 51 and used for setting a foot pad 300. . The foot pad 300 provided on the setting portion 52 is located at the rear side of the first housing 201 and protrudes downward from the bottom of the first housing 201 through the first housing 201 .

Referring to Fig. 2, Fig. 4, Fig. 6 and Fig. 7, the connecting rod assembly 6 includes a first rod 61 pivotally connected to the second base 12 of the base 1, a second rod 62 located below the first rod 61 and pivotally connected between the first rod 61 and the setting portion 52 of the lifting support member 5, and a pivot member 63 extending along the front-rear direction D1 and penetrating the pivot point between the first rod 61 and the second rod 62 and having the second sliding portion 631. The pivot member 63 has a second sliding portion 631 in a convex block structure and can be slidably connected to the second guide portion 34 along the second guide portion 34. The connecting rod assembly 6 can be switched between a retracted state (see FIG. 2 ) in which the angle between the first rod 61 and the second rod 62 is relatively small, and an extended state (see FIG. 9 ) in which the angle between the first rod 61 and the second rod 62 is relatively large.

Referring to Figures 1 to 3, when the rotating member 2 is in the first position, the second housing is closed relative to the first housing 201. The first sliding portion 33 (see Figure 6) of the sliding member 3 is located at the end of the guide section 231 of the first guide portion 23 of the rotating member 2 (see Figure 4), and the sliding member 3 is in the third position, and the auxiliary member 4 is stretched and elastically deformed in this state. The connecting rod assembly 6 is in the retracted state with a relatively small angle between the first rod 61 and the second rod 62. The lifting support member 5 is in the initial position. At this time, the downward protrusion amount of the foot pad 300 on the lifting support member 5 and the other foot pads 300 (not shown) of the first shell 201 (at the front side) relative to the first shell 201 can be consistent.

Referring to Figures 8 and 9, when the rotating member 2 rotates from the first position to the transition position, the second housing is opened relative to the first housing 201. The first sliding portion 33 (see Figure 6) of the sliding member 3 is located at the junction of the guide section 231 and the holding section 232 of the first guide portion 23 of the rotating member 2 (see Figure 5), driving the sliding member 3 to slide along the left-right direction D2 to the fourth position, so as to link the connecting rod assembly 6 to convert to the unfolded state with a relatively large angle between the first rod 61 and the second rod 62, and the second rod 62 of the connecting rod assembly 6 links the lifting support member 5 to slide downward to the supporting position. At this time, the foot pad 300 on the lifting support 5 protrudes downwardly relative to the first housing 201 more than other foot pads 300 (not shown) on the first housing 201 (front side), so the rear side of the first housing 201 is supported higher than the front side. This can increase the heat dissipation space of the electronic device 200 (laptop) during use and increase the comfort when using the keyboard on the first housing 201 of the electronic device 200. It should be noted that the auxiliary member 4 recovers from the stretched and elastically deformed state in this state and provides resistance to prevent the sliding member 3 from sliding toward the third position, so as to prevent the lifting support member 5 from retreating upward from the raised position to the initial position due to the weight of the electronic device 200.

Referring to FIGS. 10 and 11 , when the rotating member 2 rotates from the transition position to the second position, the second housing is completely opened relative to the first housing 201 . The first sliding part 33 (see Figure 6) of the sliding part 3 is located at the end (see Figure 6) of the maintaining section 232 of the first guide part 23 of the rotating part 2, and the sliding part 3 is maintained on the first In the fourth position, the connecting rod group 6 is maintained in the deployed state, and the lifting support member 5 is maintained in the elevated position. That is to say, when the rotating member 2 rotates from the transition position to the second position, the position of the lifting support member 5 does not change. It should be noted that during the rotation of the rotating member 2 between the transition position and the second position, the first sliding portion 33 (see FIG. 6 ) of the sliding member 3 rotates at the first position of the rotating member 2 . The maintenance section 232 (see FIG. 6 ) of the guide part 23 slides. Since the maintenance section 232 extends straightly around the rotation axis A, the lifting support 5 is lifted by the weight of the electronic device 200 at this time. The pressure received will not be transmitted back to the rotating part 2 through the sliding part 3 . At the same time, the sliding member 3 is maintained in the fourth position, the connecting rod group 6 is maintained in the deployed state, and the lifting support member 5 is maintained in the elevated position.

Subsequently, when the rotating member 2 rotates back to the first position, the second housing is closed again relative to the first housing 201, and the lifting support member 5 is also returned to the initial position in conjunction, which will not be described again here. . When the rotating member 2 is in the first position and the second housing is closed relative to the first housing 201, the foot pad 300 on the lifting support member 5 is less protruding relative to the first housing 201. Therefore, the electronic device 200 can be easily stored when not in use.

Referring to FIGS. 12 and 13 , in a modified embodiment, when the connecting rod assembly 6 is in the deployed state, the angle R between the first rod 61 and the second rod 62 is greater than 180 degrees and less than or equal to 185 degrees, that is, at this time, the first rod 61 and the second rod 62 are slightly recurved. Specifically, the angle R between the first rod 61 and the second rod 62 is approximately 181.8 degrees in the modified embodiment. In addition, the first rod 61 of the connecting rod assembly 6 has a first stopper 611, and the second rod 62 has a second stopper 621. When the connecting rod assembly 6 is in the unfolded state, the first stopper 611 abuts against the second stopper 621 to help bear the pressure on the connecting rod assembly 6 due to the weight of the electronic device 200. This prevents the pressure on the lifting support member 5 due to the weight of the electronic device 200 from being transmitted back to the rotating member 2 through the connecting rod assembly 6 (and the sliding member 3), and prevents the lifting support member 5 from returning upward to the initial position.

In addition, it should be noted that, in addition to being applied to this embodiment in the form of a single rotating shaft, the present invention can also be applied to other embodiments in the form of a double rotating shaft (not shown in the figure). In other embodiments of the above-mentioned dual-shaft form, the rotating part serves as a connecting seat, and the rotating part (connecting seat) is also provided with another rotating part suitable for disposing the second housing.

In summary, the lifting support member 5 in the new rotating shaft 100 can be linked with the rotating member 2 through the sliding member 3 and the connecting rod assembly 6. When the rotating member 2 rotates from the first position to the second position and the sliding member 3 slides from the third position to the fourth position, the lifting support member 5 can be linked to move downward from the initial position to the raised position. Therefore, when the rotating shaft 100 is applied to an electronic device 200 such as a laptop computer, the lifting support member 5 or the foot pad 300 provided on the lifting support member 5 can be used to conveniently raise the back side of the laptop computer when using the laptop computer. In addition, since the auxiliary member 4 connected between the sliding member 3 and the base 1 can provide resistance to prevent the sliding member 3 from sliding toward the third position, the sliding member 3 can be prevented from returning to the third position after sliding to the fourth position, thereby preventing the lifting support member 5 from retreating upward from the raised position to the initial position due to the weight of the device used.

However, the above are only examples of the present invention, and should not be used to limit the scope of the present invention. All simple equivalent changes and modifications made based on the patent scope of the present invention and the content of the patent specification are still within the scope of the present invention. Within the scope covered by this new patent.
