Detailed Description
For a further understanding of the objects, construction, features, and functions of the invention, reference should be made to the following detailed description of the preferred embodiments.
Certain terms are used throughout the description and claims to refer to particular components. It will be appreciated by those of ordinary skill in the art that manufacturers may refer to a component by different names. The description and claims do not take the form of an element differentiated by name, but rather by functional differences. In the following description and in the claims, the terms "include" and "comprise" are used in an open-ended fashion, and thus should be interpreted to mean "include, but not limited to.
Referring to fig. 1A-4C, a first embodiment of the liftable track point assembly of the present invention is disclosed. The pointing stick assembly can be lifted relative to the surface of the substrate of the electronic device, so that the pointing stick is selectively highlighted or hidden, the volume of the electronic device is reduced, and the pointing stick is effectively prevented from being misoperation under a specific state. The pointing stick assembly can be applied to keyboards, notebook computers, desktop computers, smart phones, and other electronic devices, but the invention is not limited thereto.
The liftable track point assembly includes a first link 10, a second link 20, and a track point 30.
The pointing stick 30 is perpendicular to the surface of the substrate 1, and may be protruding from a substrate 1 or penetrating through an opening in the substrate 1. The pointing stick 30 includes a first portion 31 and an operating portion 32.
The operation portion 32 is a user operable portion, for example, the operation portion 32 is a pointing stick portion tip stick cap or an operation ball.
The first part 31 is used for being held, and generates vertical displacement relative to the surface of the substrate by the change of the holding, thereby driving the whole pointing stick 30 to lift relative to the substrate 1. The first portion 31 and the operation portion 32 may be located on different sides of the substrate 1 (e.g., as shown in fig. 1A, 1B, 2A, and 2B), or may be located on the same side of the substrate 1 (e.g., as shown in fig. 4C). As shown in fig. 2A and 2B, the operation portion 32 is located on the front surface of the substrate 1, the first portion 31 is located on the back surface of the substrate 1, and when the first portion 31 is held close to the substrate 1, the operation portion 32 is driven to lift or protrude from the front surface of the substrate 1; when the first portion 31 is held away from the substrate 1, the operation portion 32 is moved downward or brought in from the front surface of the substrate 1. As shown in fig. 4C, the operation portion 32 and the first portion 31 are both located on the front surface of the substrate 1, and when the first portion 31 is abutted against the substrate 1, the operation portion 32 is driven to descend or be accommodated from the front surface of the substrate 1; when the first portion 31 is held away from the substrate 1, the operation portion 32 is driven to rise or protrude from the front surface of the substrate 1; preferably, the middle of the abutting portion 11 has a partial structure with an opening for the pointing stick 30 (for example, a stick portion of the pointing stick, a set screw, as shown in fig. 1A, 1B, and 4C), so that the first abutting portion 111, the second abutting portion 112, and the like thereof are abutted while ensuring the posture of the pointing stick when the abutting is moved.
The first portion 31 may be separated from the substrate 1 by losing the holding force of the first link 10 and pushing by other members. The other member may be a member of the flip electronic device that is located in one of the flip and the body with the pointing stick 30, such as the pointing stick 30 being located in the body, the pushing member being located in the flip, or directly the base portion of the flip; other components may be a restoring member (such as a spring 33 extending laterally as shown in fig. 1A and 1B) integrally combined with the pointing stick, or a restoring member additionally abutting between the pointing stick 30 and the base plate 1 (such as a spring 33 in fig. 3A and 3B); the invention is not limited thereto.
Preferably, the pointing stick 30 further comprises a return force portion 33, the return force portion 33 urging the pointing stick 30 away from the substrate 1. When the first part 31 receives the holding force, the restoring force part 33 drives the first part 31 to abut against the component applying the holding force, so that the pointing stick 30 is prevented from being skewed or swayed relative to the substrate; when the first portion 31 is not subject to the holding force, the restoring force portion 33 drives the first portion 31 to displace away from the substrate 1. The restoring force portion 33 and the operation portion 32 may be located on the same side of the substrate 1, where the restoring force portion 33 acts to drive the operation portion 32 to lift or extend from the front surface of the substrate 1, which may ensure the extending distance of the operation portion 32 for the convenience of user operation; the restoring force portion 33 and the operating portion 32 may also be located at opposite sides of the substrate 1, where the restoring force portion 33 acts to drive the operating portion 32 to descend from the front surface of the substrate 1 or to be accommodated in the storage. The restoring force portion 33 may be combined with the first portion 31, such as an inclined spring 33 (as shown in fig. 1A and 1B) extending laterally from the first portion 31; when the first portion 31 and the operation portion 32 are fixed in position, the restoring force portion 33 may be provided between the substrate 1 and the operation portion 32. The restoring force portion 33 may also be a spring member (as shown in fig. 3A and 3B) located between the first portion 31 and the substrate 1, or other structures that can generate restoring force based on, but not limited to, elasticity, air pressure, hydraulic pressure, electromagnetic force, magnetic attraction force, etc. to restore the original shape or size, which is not limited to the present invention.
The first link 10 is fixed to the substrate 1 and is movable in a first direction 1S parallel to the surface of the substrate 1 and a direction opposite to the first direction 1S'. The directions 1S and 1S' may be parallel to the longitudinal direction of the first link 10 (as shown in fig. 1A and 1B), or may form a small angle with the longitudinal direction of the first link 10.
The first link 10 comprises an abutment 11, the abutment 11 being adapted to confine the first portion 31 of the pointing stick 30 between it and the base plate 1. When a part of the contact portion 11 is closer to the substrate 1 than the other part and thus the part contacts the first portion 31 of the pointing stick 30, the pointing stick 30 contacts the substrate 1; when the part does not contact the first portion 31 of the pointing stick 30, the first portion 31 of the pointing stick 30 is displaced away from the substrate 1, and the pointing stick 30 is lifted and lowered relative to the substrate 1. The contact portion 11 includes a first contact portion 111 that contacts the pointing stick 30 with the substrate 1 when the first contact portion contacts the first portion 31 of the pointing stick 30.
The abutment portion 11 may further include a second abutment portion 112, where the second abutment portion 112 is spaced apart from the substrate relative to the first abutment portion 111, such that when the second abutment portion 112 abuts the first portion 31 of the pointing stick 30, there is a displacement of the first portion 31 away from the substrate 1 relative to when abutted by the first abutment portion 111, thereby lifting the pointing stick 30 relative to the substrate 1. Alternatively, the abutment portion 11 is provided with the third relief 113 without providing the second abutment portion 112 at a position corresponding to the second abutment portion 112, and the third relief 113 does not abut against the first portion 31 when moved to correspond to the first portion 31; the third yielding position 113 may be a vertical distance from the first abutting position 111 greater than the movable range of the first portion 31, or may be a hole, which directly allows the first portion 31 to pass therethrough (e.g. replace the second abutting portion 112 in fig. 4A with the third yielding position 113).
When the first link 10 moves in the direction 1S or 1S', the portion of the abutment 11 aligned with the position of the pointing stick 30 is switched between the first abutment 111 and the second abutment 112 (or the third relief 113), and in order to achieve smooth switching, a transition region is provided between the first abutment 111 and the second abutment 112 (or the third relief 113) to form an inclined smooth transition, for example, an inclined straight line, an inclined curved line, or both ends of the inclined straight line or curved line may be smoothed.
The second link 20 is fixed to the substrate 1 and is movable in a second direction 2S parallel to the surface of the substrate 1 and a direction opposite to the second direction 2S'. The directions 2S and 2S' may be parallel to the length direction of the second link 20, or may form a small angle with the length direction of the second link 20.
The first connecting rod 10 and the second connecting rod 20 form a certain included angle (a second included angle theta 2), and are coupled by the first coupling part 12 in the first connecting rod 10 and the second coupling part 22 in the second connecting rod 20 at the junction of the first connecting rod 10 and the second connecting rod, and when the second connecting rod 20 moves along the direction 2S/2S ', the first connecting rod 10 is driven to move along the direction 1S/1S' by the coupling relation of the first coupling part 12 and the second coupling part 22. One of the first coupling part 12 and the second coupling part 22 includes a boss, and the other includes a chute into which the boss can be coupled, so that when one of the first link 10 and the second link 20 moves, the other of the first link 10 and the second link 20 is moved by the coupled relationship of the boss with respect to the chute in the chute extending direction 3S.
As shown in fig. 1A, 1B and 1C, the first coupling portion 12 includes a protrusion 121, and the second coupling portion 22 includes a chute 221. When the second link 20 moves in the direction 2S, the chute 221 is driven to move to 221 'in the direction 2S, and the boss 121 coupled into the chute 221 is moved to 121', thereby driving the first link 10 to move in the direction 1S; when the second link 20 moves in the direction 2S, the chute 221' is driven to move to 221 in the direction 2S ', and the boss 121' coupled into the chute 221' is moved to 121, thereby driving the first link 10 to move in the direction 1S '. The angle of the extending direction 3S/3S 'of the chute 221 in the moving side with respect to the moving direction 2S or 2S' of the second link 20 is set to θ1, and the angle of the moving direction 1S or 1S 'of the first link 10 with respect to the moving direction 2S or 2S' of the second link 20 is set to θ2 (to avoid confusion, θ1, θ2 are defined in polar coordinates, that is, θ1, θ2 are polar angles with respect to the moving direction of the polar axis of the second link and with respect to the moving direction of the chute 221 in the extending direction 3S in the moving side and the moving direction of the first link, respectively). The first link 10 is typically disposed at an angle substantially perpendicular to the direction of movement of the second link 20, as shown in fig. 1A.
When the second connecting rod 20 moves, the stress F exerted on the convex column 121 by the chute 221 comprises a radial component force F1 along the moving direction of the first connecting rod 10 and a tangential component force F2 perpendicular to the moving direction, wherein the radial component force F1 is an effective component force for driving the first connecting rod 10 to move; the tangential component F2 has substantially no effect, it creates a shearing force on the stud and also has a shearing damage to the other components controlling the first link 10 in the direction 1S or 1S', so that it is necessary to reduce the tangential component F2. When the first link 10 is perpendicular to the second link 20 (i.e., θ2=90° or 270 °), the tangential component force at this time is large, as shown in fig. 1A; the angle θ2 between the first link 10 and the second link 20 is adjusted to reduce the stress, as shown in fig. 1B.
As shown in (i) of fig. 1C, θ2 is illustrated when θ1∈ (0 °,90 °), and thus it can be seen that the optimal angle of θ2 is θ1+270°, where θ2=270° -2×θ1 is equal to the tangential component force F2 of θ2=270°, and further it can be seen that θ1∈ (0 °,45 °), θ2∈ (270 °,2×θ1+270 °); θ1 ε [45 °,90 °), θ2 ε (270 °,360 °). U.S. Pat. No. 0 °,2 θ1-90 °); in addition, considering that the first link 10 and the second link 20 have a certain gap with the member controlling the moving direction thereof, the angle formed therebetween is slightly changed, particularly when moving in the opposite directions 1S 'and 2S', respectively, the first link 10 is not smoothly returned, and thus, considering this, both sides give a margin of 3 to 5 °. Because the optimal angle of theta 2 is 270-theta 1, theta 2 epsilon [ 265-theta 1, 275-theta 1] can be set to ensure that tangential component force is small enough, almost negligible and smooth movement.
As shown in (ii) of fig. 1C, when θ1∈ (270 °,360 °), further analysis shows that the optimal angle of θ2 is θ1-270 °, where θ2=2×θ1-630 ° is equal to the tangential component force F2 of θ2=90°, and further that θ1∈ (270 °,315 °), θ2∈ (2×θ1-270 °,360 °)) u [0 °,90 °); θ1∈ [315 °,360 ° ], θ2∈ (2×θ1-630 °,90 °), the tangential component force F2 is smaller than the tangential component force F2 of the first link 10 and the second link 20 when they are vertically arranged; in addition, considering that the first link 10 and the second link 20 have a certain gap with the member controlling the moving direction thereof, the angle formed therebetween is slightly changed, particularly when moving in the opposite directions 1S 'and 2S', respectively, the first link 10 is not smoothly returned, and thus, considering this, both sides give a margin of 3 to 5 °.
That is, the tangential component force applied to the movement of the first link 10 and the second link 20 when the following condition (1) is satisfied is smaller than when the two are vertically arranged:
preferably, considering the 5 ° margin, the tangential force component to which the first link 10 and the second link 20 are moved when the following condition (2) is satisfied is smaller than when the two are vertically disposed:
preferably, θ2 satisfying the following condition (3) allows the optimal setting, and the tangential component is almost negligible:
in order to allow the first link 10 and the second link 20 to move only in the directions 1S/1S 'and 2S/2S' parallel to the surface of the substrate 1, respectively, it is necessary to provide corresponding structures on the first link 10, the second link 20, and the substrate for restriction.
