Detailed Description
In order to make the technical solutions of the present invention better understood, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1 to 9, the embodiment of the present invention discloses a notebook computer, which includes a display end 10, a system end 20, a rotating shaft assembly 30 and a damping applying mechanism 40. The rotating shaft assembly 30 includes a shaft body 31 and a shaft sleeve 32 sleeved on the shaft body 31; the display end 10 is fixedly connected with the shaft sleeve 32 by the first bearing frame 11, so that when the display end 10 rotates, the shaft sleeve 32 rotates to form relative rotation with the shaft body 31; the system end 20 is fixedly connected to the shaft 31 via the second bracket 21. In the present invention, the damping applying mechanism 40 is used for applying a first damping to the space between the shaft 31 and the sleeve 32 when the display end 10 is in a stationary state, and for releasing (or canceling) the first damping applied to the space between the shaft 31 and the sleeve 32 when the display end 10 rotates. Thus, the damping experienced by the display end 10 when in a stationary state is greater than the damping experienced by the display end 10 when in a rotating state.
According to the invention, by arranging the damping applying mechanism 40, the damping applying mechanism 40 applies damping to the rotating shaft assembly 30 when the display end 10 is static, and releases the application to the rotating shaft assembly 30 when the display end 10 rotates, so that the display end 10 can keep a stable state without shaking easily when the display end 10 is static, and a larger force is not applied when the opening angle needs to be changed or the display end 10 is opened.
In order to prevent the display end 10 from being in a completely free state during the opening process or the process of changing the opening angle of the display end 10, in a preferred embodiment of the present invention, the shaft 31 and the shaft sleeve 32 are brought into contact with each other to form a second damping, so that the display end 10 is opened under the limitation of the second damping.
It should be noted that: the damping value of the second damping, which cannot be set to such an extent that the display terminal 10 can be stably maintained at the opened angle, should be much smaller than that of the first damping.
In a preferred embodiment of the present invention, the notebook computer further comprises a rotation detection mechanism 50, the rotation detection mechanism 50 is configured to determine whether the display terminal 10 is in a rotating state, and the damping application mechanism 40 applies or releases the first damping between the shaft body 31 and the shaft sleeve 32 according to the determination result of the rotation detection mechanism 50. In the present embodiment, the rotation detection mechanism 50 is used to determine whether the display end 10 rotates, and in a preferred embodiment, the rotation detection mechanism 50 obtains the information whether the display end 10 rotates by determining whether the sleeve 32 rotates. When the rotation detection mechanism 50 determines that the display end 10 rotates, the damping application mechanism 40 cancels the application of the first damping between the shaft body 31 and the shaft sleeve 32; when the rotation detection mechanism 50 determines that the display end 10 stops rotating, the damping application mechanism 40 applies the first damping between the shaft 31 and the shaft sleeve 32 again; when the rotation detecting mechanism 50 determines that the display terminal 10 is in the stationary state, the damping applying mechanism 40 does not cancel the first damping.
A preferred embodiment of the present invention provides a damping applying mechanism 40, specifically, as shown in fig. 1 to 7, a core hole 311 is opened at an end portion of the shaft body 31; the damping applying mechanism 40 includes: a spindle 41, a damping mass 42 and an actuating assembly. The mandrel 41 extends into the mandrel hole 311; the damping block 42 is radially provided with a core hole 311, and the head part of the damping block 42 can protrude out of the outer peripheral surface of the shaft body 31 or retract into the shaft body 31 through radial movement; the actuating assembly is used for driving the mandrel 41 to move axially; wherein: the tail part of the damping block 42 protrudes out of the hole wall of the core hole 311; the mandrel 41 is formed with a tapered step 411; the actuating assembly drives the mandrel 41 according to the judgment result of the rotation detection mechanism 50, so that when the display end 10 is in a static state, the actuating assembly drives the mandrel 41 to push the tail part of the damping block 42 through the conical step 411 to enable the head part of the damping block 42 to tightly abut against the hole wall of the inner hole of the shaft sleeve 32, and when the display end 10 is in a rotating state, the actuating assembly drives the mandrel 41 to reversely move to enable the conical step 411 to release the pushing against the tail part of the damping block 42.
The operation principle of the damping applying mechanism 40 provided in the above embodiment is:
when the rotation detection mechanism 50 determines that the sleeve 32 is in a static state, as shown in fig. 2 and 3, it indicates that the display end 10 is also in a static state, and at this time, the actuating assembly makes the spindle 41 be in a position closest to the inner end of the core hole 311, the shaft body 31 on the left side of the tapered step 411 (the diameter of the shaft body 31 on the left side of the tapered step 411 is larger than that of the shaft body 31 on the right side of the tapered step 411) abut against the tail of the damping block 42, so that the head of the damping block 42 abuts against the inner hole wall of the sleeve 32, so that the display end 10 is kept static in the first damping state.
When the rotation detection mechanism 50 determines that the sleeve 32 is switched from the rotating state to the stationary state, the actuating assembly drives the spindle 41 to move rightward, and at the same time, the tapered step 411 pushes against the tail of the damping block 42, so that the damping block 42 extends out of the shaft body 31, and after the tail of the damping block 42 slides over the tapered step 411, the shaft body 31 on the left side of the tapered step 411 abuts against the tail of the damping block 42, as shown in fig. 2 and 3, so that the head of the damping block 42 abuts against the inner hole wall of the sleeve 32, so that the display end 10 is kept stationary in the first damping state.
When the rotation detection mechanism 50 determines that the sleeve 32 rotates, as shown in fig. 5 and 6, the actuating assembly drives the spindle 41 to move towards the outer end, and finally the shaft body 31 on the right side of the tapered step 411 is opposite to the tail of the damping block 42, at this time, the tail of the damping block 42 is no longer abutted by the shaft body 31, so that the head of the damping block 42 is not abutted to the inner hole wall of the sleeve 32, the first damping applied to the sleeve 32 is cancelled, and the display end 10 can rotate more smoothly.
The advantages of the above embodiment are:
1. the damping applying mechanism 40 applies the first damping by means of mechanical friction, and the applying is more reliable and simpler.
2. The key components (such as the damping block 42 and the spindle 41) of the damping applying mechanism 40 are disposed in the shaft body 31, which makes the structure more compact, and does not increase the thickness of the notebook computer.

The advantages of the above embodiment are: the magnetic force adsorption effect of the electromagnet 431 and the permanent magnet 432 and the effect of the two pressure springs are comprehensively utilized, so that the mandrel 41 drives the damping block 42 through axial movement, and the design is ingenious.
