Description

Axis

The present invention relates to a rotating shaft, and in particular to a rotating shaft that can be applied to electronic devices such as notebook computers.

When using electronic products such as laptops, general users often need to use a heat sink to raise the back of the laptop to increase the heat dissipation space of the laptop and increase the comfort when using the laptop keyboard. However, the above-mentioned heightening rack is not very convenient in terms of storage or use. Therefore, how to conveniently raise the back of the laptop when using the laptop is an important issue.

Therefore, an object of the present invention is to provide a rotating shaft that can improve at least one problem in the prior art.

Therefore, in some embodiments, the novel rotating shaft includes a base, a rotating member, a sliding member, a lifting support member, and a connecting rod assembly. The rotating member is disposed on the base and can rotate between a first position and a second position relative to the base around a rotating axis parallel to a left-right direction, and the rotating member has a first guide portion extending around the rotating axis. The sliding member is disposed on the base and can slide along the left-right direction relative to the base, and the sliding member has a first sliding portion that can be slidably connected to the first guide portion along the first guide portion, and a second guide portion extending along an up-down direction. The lifting support member is pivoted on the base and can pivot between an initial position and a raised position located below the initial position relative to the base. The connecting rod assembly includes a first rod member pivotally connected to the base, a second rod member located below the first rod member and pivotally connected between the first rod member and the lifting support member, and a second sliding portion provided at the pivot point between the first rod member and the second rod member and slidably connected to the second guide portion along the second guide portion, and the connecting rod assembly can be changed between a folded state and an extended state. When the rotating member is in the first position, the connecting rod assembly is in the folded state, and the lifting support member is in the initial position; when the rotating member rotates to the second position, the sliding member is driven to slide along the left-right direction to link the connecting rod assembly to the extended state, and the second rod member of the connecting rod assembly links the lifting support member to pivot downward to the raised position.

In some implementations, the first guiding portion is a groove structure, and the first sliding portion is a bump structure.

In some implementations, the rotating member further has an arc convex surface, the first guide portion is formed on the arc convex surface, the sliding member further has an arc concave surface matching the arc convex surface, and the first sliding portion is formed on the arc concave surface.

In some implementations, the second guiding portion is a groove structure, and the second sliding portion is a bump structure.

In some embodiments, the connecting rod assembly further includes a pivot member extending along a front-rear direction and penetrating through a pivot point between the first rod and the second rod and having the second sliding portion.

In some embodiments, the base has a guide post extending along the left-right direction, and the sliding member further has a sliding sleeve that can be slidably mounted on the guide post along the left-right direction.

In some implementations, the lifting support can pivot relative to the base between the initial position and the raised position about a pivot axis, and the pivot axis is parallel to a front-to-back direction.

In some embodiments, the lifting support is in the shape of a rod and has a fixed end pivotally mounted on the base and a supporting end pivotally connected to the second rod of the connecting rod assembly.

The lifting support member in the novel shaft can be linked with the rotating member through the sliding member and the connecting rod assembly. When the rotating member rotates from the first position to the second position, the lifting support member can be linked to pivot downward from the initial position to the raised position. Therefore, when the shaft is applied to electronic devices such as laptop computers, the lifting support member or the foot pad provided on the lifting support member can be used to conveniently raise the back side of the laptop computer when using the laptop computer.

Referring to FIG. 1 to FIG. 3 , an embodiment of the novel rotating shaft 100 is applicable to an electronic device 200, which is exemplified as a laptop computer, but is not limited thereto. The electronic device 200 has a first housing 201 and a second housing (not shown). The first housing 201 may 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 relative to the first housing 201. The rotating shaft 100 includes a base 1, a rotating member 2, a sliding member 3, a lifting support member 4, and a connecting rod assembly 5.

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 11 for being arranged at the rear side of the first housing 201, a second base 12 arranged on the first base 11, and a rotation shaft 13 arranged on the rear side of the first base 11 in a front-rear direction D1 (arrow facing forward, reverse direction is rear) and extending along a left-right direction D2 (arrow facing right, reverse direction is left). The first base 11 has a guide post 111 extending along the left-right direction D2, and a setting plate 112 extending upward from the front side along a vertical direction D3 (arrow facing upward, reverse direction is downward) and with the plate surface facing forward. The second base 12 is arranged at the end of the guide post 111 of the first base 11, and the second base 12 has an extension portion 121 extending forward.

Referring to Figures 2 to 5, the rotating member 2 is disposed on the rotating shaft 13 of the base 1 and is suitable for being provided with the second shell. The rotating member 2 can rotate between a first position (see Figure 2) and a second position (see Figure 8) relative to the base 1 around a rotating shaft A1 parallel to the left-right direction D2. The rotating shaft A1 is the axis of the rotating shaft 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, a first guide portion 23 formed in a groove structure on the arc convex surface 22 of the rotating sleeve 21 and extending obliquely around the rotating axis A1, and a mounting frame 24 extending from the rotating sleeve 21 and for mounting the second housing.

Referring to Figures 2 and 4 to 6, the sliding member 3 is provided on the guide post 111 of the base 1 and can slide along the left-right direction D2 relative to the guide post 111 of the base 1. The sliding member 3 has a sliding sleeve 31 that can be slidably mounted on the guide post 111 along the left-right direction D2, a circular arc concave surface 32 located on the rear side of the sliding sleeve 31 and matching with the circular arc convex surface 22, a first sliding portion 33 formed on the circular arc concave surface 32 with a convex block structure and able to be slidably connected to the first guide portion 23 along the first guide portion 23, and a second guide portion 34 formed on the front side of the circular arc concave surface 32 with a groove structure and extending along the up-down direction D3.

Referring to Figs. 1, 2, 4 and 5, the lifting support member 4 is in the shape of a rod and pivotally mounted on the extension portion 121 of the second base body 12 of the base 1. The lifting support member 4 can pivot around a pivot axis A2 between an initial position (see Fig. 2) and a raised position (see Fig. 8) below the initial position relative to the second base body 12 of the base 1. The pivot axis A2 is parallel to the front-rear direction D1. The lifting support member 4 has a fixed end 41 pivotally mounted on the base 1, and a supporting end 42 opposite to the fixed end 41. The bottom of the supporting end 42 is used for a foot pad 300 to be disposed. The foot pad 300 disposed at the supporting end portion 42 is located at the rear side of the first housing 201 , and passes through the first housing 201 and protrudes downward from the bottom of the first housing 201 .

Referring to FIG. 2 and FIG. 4 to FIG. 6 , the connecting rod assembly 5 includes a first rod 51 pivotally connected to the setting plate 112 of the base 1, a second rod 52 located below the first rod 51 and pivotally connected between the first rod 51 and the supporting end 42 of the lifting support member 4, and a pivot member 53 extending along the front-rear direction D1 and penetrating the pivot point between the first rod 51 and the second rod 52 and having the second sliding portion 531. The pivot member 53 has a second sliding portion 531 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 5 can be switched between a retracted state (see FIG. 2 ) in which the angle between the first rod 51 and the second rod 52 is relatively small, and an extended state (see FIG. 8 ) in which the angle between the first rod 51 and the second rod 52 is relatively large.

Referring to FIGS. 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 connecting rod assembly 5 is in the retracted state with a relatively small angle between the first rod 51 and the second rod 52. The lifting support member 4 is in the initial position. At this time, the downward protrusion of the foot pad 300 on the lifting support member 4 and the other foot pads 300 (not shown) of the first housing 201 (at the front side) relative to the first housing 201 can be consistent.

Referring to FIG. 7 and FIG. 8 , when the rotating member 2 rotates to the second position, the second housing is opened relative to the first housing 201. The sliding member 3 is driven to slide along the left-right direction D2 (sliding to the left in the figure), so as to link the connecting rod assembly 5 to the unfolded state in which the angle between the first rod 51 and the second rod 52 is relatively large, and the second rod 52 of the connecting rod assembly 5 links the lifting support member 4 to pivot downward to the raised position. At this time, the foot pad 300 on the lifting support member 4 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.

When the rotating member 2 rotates back to the first position, the second housing is closed relative to the first housing 201 again, and the lifting support member 4 is also linked to return to the initial position, which will not be described in detail 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 4 is less protruding relative to the first housing 201, so the electronic device 200 can be easily stored when not in use.

In addition, it should be noted that the present invention can be applied to other embodiments of the double-axle form in addition to the single-axle form (not shown). In the other embodiments of the double-axle form, the rotating member serves as a connecting seat, and the rotating member (connecting seat) is also provided with another rotating member suitable for the second housing to be installed.

In summary, the lifting support member 4 in the new rotating shaft 100 can be linked with the rotating member 2 through the sliding member 3 and the connecting rod assembly 5. When the rotating member 2 rotates from the first position to the second position, the lifting support member 4 can be linked to pivot 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, the lifting support member 4 or the foot pad 300 provided on the lifting support member 4 can be used to conveniently raise the back side of the laptop when using the laptop. Thereby, the heat dissipation space of the electronic device 200 (laptop) is increased during use, and the comfort when using the keyboard on the first shell 201 of the electronic device 200 is increased.

However, the above is only an example of the implementation of the present invention, and it cannot be used to limit the scope of the implementation of the present invention. All simple equivalent changes and modifications made according to the scope of the patent application of the present invention and the content of the patent specification are still within the scope of the present patent.
