Description

Electronic device

The present invention relates to an electronic device, and more particularly to an electronic device that is pivoted by a ratchet.

In daily life, many items use pivoting mechanisms, such as doors, windows, rearview mirrors or notebook computers, electronic dictionaries, personal digital assistants (PDAs), mobile phones and other electronic devices, all of which must rely on pivoting mechanisms. To achieve the function of rotating or switching the body. The pivoting mechanism generally has a rotating shaft and a shim group, and the frictional force between the stator and the rotor (ie, the damped pivot) is used to offset the torque generated by the gravity of the body to achieve the positioning effect in the rotating stroke. Therefore, the design of the pivot mechanism can affect the convenience and reliability of the user operating the above device.

Taking a notebook computer as an example, there is currently a notebook computer that produces a large size on the market. If the frictional force of the damped pivot is too large, the user needs to simultaneously load the damper pivoting force when performing the pivoting operation. The weight of the display, so the user is more laborious when opening the display.

The present invention provides an electronic device for reducing the resistance of the display relative to the pivoting of the seat so that the user can save effort when opening the display.

The electronic device disclosed in the present invention comprises a first seat body, a second seat body, a pivoting member and a buffer assembly. The second body is pivoted to the first seat. Pivoting member contains a A ratchet assembly and a second ratchet assembly. The first ratchet assembly is disposed on the second seat. The second ratchet assembly is engageable with the first ratchet assembly such that the second ratchet assembly has a single direction of rotation, and the second ratchet assembly is slidably disposed on the first seat to have a snapped position and a disengaged position. The buffer assembly is located between the first seat and the second seat, and the opposite ends are respectively connected to the first seat and the second seat. Wherein, when the second ratchet assembly is in the engaged position, the second seat body is expandable relative to the first seat body in a single rotational direction by the engagement of the first ratchet assembly and the second ratchet assembly, when the second ratchet assembly is in the disengaged position The first ratchet assembly is separated from the second ratchet assembly such that the second base body is rotatable in opposite directions to be relatively close to the first seat body, and the second seat body is subjected to an elastic buffering force of the cushioning assembly.

According to the electronic device disclosed in the present invention, the first seat body and the second body are allowed to achieve a one-way rotation limiting effect between the first seat body and the second seat body through the assistance of the first ratchet assembly and the second ratchet assembly. The pivot between the seats can be a low-damping pivot or even an undamped pivot, so that the user can complete the second opening by the first ratchet assembly and the second ratchet assembly only by overcoming the weight of the second seat. The operation of the seat body, in turn, can be more labor-saving in the opening operation of the second seat.

In addition, since the buffering assembly is disposed between the first seat body and the second seat body, when the second seat body is fitted to the first seat body, the second seat body is affected by the elastic buffering force of the buffer component and can be slowed down. The impact force when the second body covers the first seat.

The above description of the present invention and the following description of the embodiments are intended to illustrate and explain the principles of the invention, and to provide a further explanation of the scope of the invention.

As shown in FIGS. 5A and 5B, when the user wants to open the second body 200, the user can first press the pressing lever 530 to abut each of the abutting protrusions 522 of the connecting rod 520. The stop surface 513a of the stop protrusion 513 drives the second ratchet assembly 420 to be in the engaged position. When the second ratchet assembly 420 is in the engaged position, the first ratchet assembly 410 is located in the receiving groove 421a of the second ratchet assembly 420, and the resisting members 422 are respectively located in the slots 412 to enable the first ratchet assembly 410 to have Single direction of rotation. In detail, when the first ratchet assembly 410 is rotated by the second base 200 and is rotated in the direction indicated by the arrow a, the inclination is gentler. The first surface 413 is respectively used to push the resisting members 422 relative to the receiving accommodating grooves 421a to enable the first ratchet assembly 410 to rotate relative to the second ratchet assembly 420. However, when the first ratchet assembly 410 is rotated by the second base 200 and is rotated in the direction indicated by the arrow b, the second surfaces 414 which are steeply inclined are respectively used to stop the resisting members 422 to block the second. The ratchet assembly 420 rotates in the direction indicated by arrow b. That is, the second seat body 200 can be opened relative to the first seat body 100 through the first ratchet assembly 410 and the second ratchet assembly 420, and the second seat body 200 can be prevented from being relatively closed on the first seat body 100.

As can be seen from the above, the first ratchet assembly 410 and the second ratchet assembly 420 have a limiting effect of unidirectional rotation. Therefore, in the embodiment, the pivot between the first base 100 and the second base 200 can adopt a low damping pivot. The shaft or even the undamped pivot allows the user to complete the operation of splitting the second seat 200 through the first ratchet assembly 410 and the second ratchet assembly 420 only by overcoming the weight of the second base 200. The opening operation of the two seats 200 can be more labor-saving.

As shown in FIG. 6A and FIG. 6B, when the user wants to cover the second base 200, the user can press the swaying assembly 500 again to drive the connecting rod 520 to rotate, and the connecting rods 520 are offset. The convex portion 522 is located in the release groove portion 512. As a result, the second ratchet assembly 420 can be returned to the disengaged position by the elastic force of the reset member 540. When the second ratchet assembly 420 is in the disengaged position, the first ratchet assembly 410 and the second ratchet assembly 420 are separated from one another such that the first ratchet assembly 410 can be restored to bi-directional rotation. Therefore, in the role of the gravity of the second seat body 200, the user can cover the second seat body 200 to the first seat body 100. It should be noted that, since the buffer assembly 600 is disposed between the first base 100 and the second base 200, when the second base 200 covers the first base 100, the second base 200 is buffered. The impact of the elastic cushioning force of the assembly 600 can slow down the impact of the second seat body 200 covering the first seat body 100. Force.

According to the electronic device disclosed in the present invention, the first seat body and the second body are allowed to achieve a one-way rotation limiting effect between the first seat body and the second seat body through the assistance of the first ratchet assembly and the second ratchet assembly. The pivot between the seats can be a low-damping pivot or even an undamped pivot, so that the user can complete the second opening by the first ratchet assembly and the second ratchet assembly only by overcoming the weight of the second seat. The operation of the seat body, in turn, can be more labor-saving in the opening operation of the second seat.

In addition, since the buffering assembly is disposed between the first seat body and the second seat body, when the second seat body is fitted to the first seat body, the second seat body is affected by the elastic buffering force of the buffer component and can be slowed down. The impact force when the second body covers the first seat.
