Description

Positioning module and support device

Technical Field

The present invention relates to a positioning mechanism, and more particularly, to a positioning module and a bracket device for improving the convenience of operation by using a non-clearance tenon structure.

Background

In products such as a POS system or a screen holder, a user can freely adjust a screen angle by using a rotating shaft, and some products can even add a plurality of rotating shafts to increase the degree of freedom of the angle or be more favorable for storage of the products. However, since such products generally have a screen touch function, the rotation shaft itself must have a large torque to avoid the rotation of the screen due to the touch of the user. However, under the condition of multiple rotating shafts and large torque, the user is difficult to operate due to the problem of the linkage of the rotating shafts.

In order to avoid the problem of linkage of multiple rotating shafts, one solution is to add a tenon at the rotating shaft; although the rotating shaft can be fixed, a gap is reserved for the common clamping tenon, so that the clamping tenon cannot be inserted due to tolerance, and the gap can cause a serious screen shaking problem (particularly obvious feeling when a touch screen is operated) due to the fact that the moment multiple is amplified.

Therefore, how to overcome the above-mentioned drawbacks by improving the structure design has become one of the important issues to be solved in the art.

First embodiment

Please refer to fig. 1 to 8, which are a schematic perspective view of one viewing angle, a schematic perspective view of another viewing angle, a cross-sectional view of a section III-III in fig. 2, an exploded schematic view, a schematic view of a first usage state, a schematic view of a second usage state, a schematic view of a third usage state, and a schematic structure diagram of a positioning module according to a first embodiment of the present invention. As shown in the drawings, the first embodiment of the present invention provides a positioning module P, which includes a fixed unit P1, a first movable unit P2, a linking unit P3 and a braking unit P4. The positioning module P of the present invention can be a positioning mechanism, and can be applied to a supporting structure of an electronic device (such as the supporting device Z shown in fig. 10, for example, but not limited to, a screen supporting structure).

First, as shown in fig. 1 to 8, the fixing unit P1 may have a positioning part P100. For example, the fixing unit P1 may include a seat member P10 and a first elastic member P11. The seat element P10 may be a base made of metal or plastic, and the body of the seat element P10 may be an L-shaped structure, but not limited thereto. The seat body element P10 may have a positioning portion P100, and the positioning portion P100 may be a column structure; the positioning portion P100 and the seat body element P10 may be independent elements, for example, the positioning portion P100 may be a screw or a stud, or the positioning portion P100 and the seat body element P10 may be a single component, that is, they are an integrated structure. The first elastic element P11 can be a spring, a tension spring or other elastic elements, one end of the first elastic element P11 is detachably connected to the seat body element P10, and the other end of the first elastic element P11 is detachably connected to the linkage unit P3. Moreover, the first movable unit P2 and the brake unit P4 are located on one side of the seat body element P10, and the first elastic element P11 and the linkage unit P3 are located on the other side of the seat body element P10. The fixed unit P1 may further include a movable slot P101, the movable slot P101 penetrating through the body of the fixed unit P1; namely, the body of the seat member P10 has a movable groove P101. The movable slot P101 may be an oblong shape, but not limited thereto.

Next, as shown in fig. 1 to 8, the first movable unit P2 can be movably connected to the fixed unit P1, and the first movable unit P2 can have an engaging portion P20. For example, the first activity unit P2 may be in a glyph shape; that is, the body of the first movable unit P2 may be circular, and a part of the side edge of the body of the first movable unit P2 may extend outward to form a protrusion P21, and the protrusion P21 may be used to connect and fix a support structure of an electronic device. At least a part of the rest side edge of the body of the first movable unit P2 can form a clamping part P20, namely, the clamping part P20 occupies 1/3 or 1/4 of the side edge of the body of the first movable unit P2; the engaging portion P20 may be a plurality of teeth (e.g. similar to the convex portion of the gear for engaging), or other teeth-type engaging structure. Moreover, the first movable unit P2 can be pivotally connected to the fixed unit P1 by a snap-fit manner or by a locking member (such as a bolt, but not limited thereto); in the embodiment, in order to facilitate understanding of the structure of the positioning module P of the present invention, the fastening structure and the locking element are omitted.

Next, as shown in fig. 1 to 7, the linking unit P3 can be movably connected to the fixing unit P1, and the linking unit P3 can have an engaging portion P30. For example, the linking unit P3 can be a plate structure, and the linking unit P3 can be triangular, 1/4 circular or other geometric shapes. The linking unit P3 body has two connected side edges, one of which can extend outward to form a pressing part P31, and the pressing part P31 and the linking unit P3 body can form an L-shape or a V-shape, but not limited thereto; in addition, the other side of the linking unit P3 body has an engaging portion P30, and the engaging portion P30 may be C-shaped, but not limited thereto. The engaging portion P30 and the linking unit P3 can be independent elements, or the engaging portion P30 and the linking unit P3 can be a single component, i.e. they are integrated. The linking unit P3 may further have a positioning groove P32, and the positioning groove P32 penetrates the body of the linking unit P3.

Next, as shown in fig. 2 to 8, the braking unit P4 can be movably connected to the fixing unit P1 and the linking unit P3, and the braking unit P4 can have a limiting portion P400. For example, the brake unit P4 includes a brake body P40 and a connecting member P41. The stopper body P40 may be a long strip plate structure, and one end of the stopper body P40 has a limiting portion P400, and the limiting portion P400 may be a single gear tooth structure or other tooth-shaped engaging structure. The stopper body P40 has a connection hole P401 penetrating the body. The connecting element P41 passes through the connecting hole P401 of the brake body P40, the movable groove P101 of the seat body element P10 and the positioning groove P32 of the linkage unit P3; wherein, the connecting element P41 can be a screw or other type of connecting element.

Therefore, when the interlocking unit P3 is located at the first position, the engaging portion P30 is away from the positioning portion P100, and the interlocking unit P3 urges the stopper unit P4 to the positioned state, so that the restricting portion P400 of the stopper unit P4 is detachably engaged with the engaging portion P20. Conversely, when the linkage unit P3 is located at the second position, the engaging portion P30 is detachably connected to the positioning portion P100, and the linkage unit P3 drives the braking unit P4 to be in the active state, so that the limiting portion P400 of the braking unit P4 engages with or disengages from the engaging portion P20.

For example, as shown in fig. 1, fig. 2, fig. 5 and fig. 8, when the linking unit P3 is located at the first position, the buckling portion P30 is away from the positioning portion P100, and the first elastic element P11 is in a contracted state; at this time, the positioning module P of the present invention is in the shape-stabilized state. Further, the linkage unit P3 can limit the movement of the connecting element P41 of the braking unit P4 in the movable groove P101 through a part of the inner wall surface of the corresponding positioning groove P32, so that the connecting element P41 cannot move or displace, the braking unit P4 is driven to be in the positioning state, and the limiting portion P400 of the braking unit P4 can be completely engaged with the engaging portion P20. When the restriction portion P400 is engaged with the engagement portion P20, the first movable unit P2 is restricted from being movable and rotatable. Specifically, since the contact point between the positioning slot P32 and the connecting element P41 is almost perpendicular to the rotating direction of the linking unit P3, there is almost no component force to rotate the linking unit P3 clockwise, and the first elastic element P11 provides the counterclockwise rotating force to the linking unit P3 to counteract the component force, so that the braking body P40 cannot move downward, and the first movable unit P2 and the object connected to the first movable unit P2 can be fixed.

Next, as shown in fig. 5 to fig. 7, when the user presses the pressing portion P31 to push the linking unit P3 from the first position to the second position (for example, clockwise rotation, but not limited thereto), so that the linking unit P3 is located at the second position and the engaging portion P30 is connected to the positioning portion P100, the positioning module P of the present invention is in the adjustment state, and the first elastic element P11 is in the extension state. At this time, the linking unit P3 can drive the connecting element P41 to displace through another part of the inner wall surface of the corresponding positioning slot P32, so as to drive the braking body P40 to move in a direction away from the first movable unit P2, so that a slight space Sp and a slight gap exist between the limiting portion P400 of the braking body P40 and the engaging portion P20 of the first movable unit P2, that is, the limiting portion P400 is not completely engaged with the engaging portion P20; and, a part of the space in the positioning groove P32 provides a space, a margin, for movement and displacement of the connecting member P41 of the brake unit P4, thereby allowing the brake unit P4 to be in an active state.

Next, when the positioning module P is in the adjusting state (i.e., the braking unit P4 is in the active state), the user can adjust the position of the first movable unit P2, for example, but not limited to, adjust the tilt angle of the first movable unit P2, i.e., the tilt angle of the first movable unit P2 relative to the ground or the tabletop. Further, as shown in fig. 5 to 7, since the restriction portion P400 is not completely engaged with the engagement portion P20, a gap Sp exists between the restriction portion P400 and the engagement portion P20; therefore, when the user rotates the first movable unit P2, the protruding portion P200 of the engaging portion P20 of the first movable unit P2 pushes against the limiting portion P400 of the brake body P40, so that the limiting portion P400 is forced to be disengaged from the recessed portion P201 of the engaging portion P20 and is abutted against the protruding portion P200; when the restriction portion P400 is separated from the recess portion P201, the restriction portion P400 drives the stopper body P40 and the connecting element P41 to move in a direction away from the first movable unit P2. Then, when the user continues to rotate the first movable unit P2, the restriction part P400 is changed from the state of abutting against the protruding part P200 to the state of being engaged with the other recessed part P201; when the restriction portion P400 is snapped into another recess portion P201, the restriction portion P400 will drive the braking body P40 and the connecting element P41 to move toward the first movable unit P2.

Wherein, the movable slot P101 of the seat body element P10 and the positioning slot P32 of the linking unit P3 can provide a space for the connecting element P41 to move; therefore, in the process that the user adjusts the position of the first movable unit P2, the connecting member P41 can be reciprocally displaced in the movable groove P101 and the positioning groove P32. In addition, in the process of adjusting the position of the first movable unit P2, the user can feel feedback of the touch and sound from the engagement of the engaging portion P20 and the restricting portion P400 and the abutment thereof, and thus can know whether the restricting portion P400 is located at the position of the recessed portion P201 of the engaging portion P20. In addition, the first movable unit P2 and the braking body P40 may be parallel to each other, and an inclined angle Na is formed between one side of the protrusion P21 and one side of the braking body P40, as shown in fig. 8; the inclined angle Na may be between 85 degrees and 250 degrees, but not limited thereto.

When the user adjusts the first movable unit P2 to a desired angle, the user can push the pressing part P31 to disengage the engaging part P30 from the positioning part P100. When the limiting portion P400 is disengaged from the engaging portion P20, the first elastic element P11 can drive the linking unit P3 to move from the second position to the first position (for example, rotate counterclockwise, but not limited thereto) by its own elastic contraction force; in addition, during the displacement of the linkage unit P3, the linkage unit P3 can drive the connecting element P41 to displace by using the positioning slot P32, so that the connecting element P41 drives the stopper body P40 to displace toward the first movable unit P2 until the limiting portion P400 of the stopper body P40 is located in the recessed portion P201 of the engaging portion P20. At this time, there is a possibility that a certain gap may still exist between the restriction portion P400 and the recessed portion P201; therefore, the user can apply force to the first movable unit P2, and since the restriction part P400 and the concave part P201 of the engaging part P20 still have a slight gap, the first movable unit P2 can still move in a small unidirectional direction, but the braking unit P4 and the linking unit P3 are driven by the elastic restoring force of the first elastic element P11, so that the restriction part P400 and the concave part P201 continuously reduce the gap until the gap disappears, and the first movable unit P2 can be completely fixed by the braking unit P4 and cannot move. That is, the positioning module P can be changed from the adjusting state to the shape-stabilized state, and the first movable unit P2 is restricted from moving and rotating.

Therefore, according to the positioning module P of the present invention, through the above-mentioned technical solution, the limiting portion P400 of the braking unit P4 is engaged with the engaging portion P20 of the first movable unit P2, that is, by using a gapless latch structure, compared with the existing latch design, the torque can be effectively reduced, the operation convenience is improved, and meanwhile, the problem of screen shaking caused by the existing latch design gap can be avoided. In addition, the positioning module P of the invention also has the advantages of small volume, high strength, easy hiding in the shell and the like.

It should be noted that, in another preferred embodiment, the gapless latch structure (i.e., the positioning module P of the present invention) may not mean that the outer shape of the limiting portion P400 of the stopper unit P4 can be completely fitted into the recessed portion P201 of the engaging portion P20 of the first movable unit P2, but when the limiting portion P400 of the stopper unit P4 is engaged with the engaging portion P20 of the first movable unit P2, both sides of the limiting portion P400 can be tightly contacted with both side walls of the tooth groove of the engaging portion P20 without a gap.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present invention.

Second embodiment

Fig. 9 is an exploded view of a positioning module according to a second embodiment of the present invention, and please refer to fig. 1 to 8. As shown in the drawings, the positioning module P of the present embodiment is substantially similar to the positioning module P of the previous embodiments, and therefore, the arrangement or operation of the same elements will not be described herein again. In this embodiment, the positioning slot P32 can have a first slot area P320 and a second slot area P321, when the linking unit P3 is located at the first position, the connecting element P41 is located at the first slot area P320, and when the linking unit P3 is located at the second position, the connecting element P41 is located at the second slot area P321; wherein the first groove region P320 is smaller than the second groove region P321.

For example, as shown in fig. 5 to 7 and 9, the positioning groove P32 of the linking unit P3 of the present invention can be irregular. The space of the first groove region P320 of the positioning groove P32 is smaller than the space of the second groove region P321. The first slot region P320 may be oblong, the second slot region P321 may be square or rectangular, and the first slot region P320 and the second slot region P321 are connected and communicated with each other, but not limited thereto. The interlocking unit P3 may have a first inner wall surface P331 and a second inner wall surface P332 corresponding to the first groove section P320, and the interlocking unit P3 may have a third inner wall surface P333 and a fourth inner wall surface P334 corresponding to the second groove section P321; first inner wall surface P331 connects second inner wall surface P332 and fourth inner wall surface P334, and third inner wall surface P333 connects second inner wall surface P332 and fourth inner wall surface P334.

Therefore, when the linking unit P3 is located at the first position, the first inner wall surface P331 of the linking unit P3 abuts against the connecting element P41 of the braking unit P4, and drives the connecting element P41 to be located at one end of the movable slot P101 and contact the seat element P10 corresponding to the inner wall surface of the movable slot P101. At this time, the connecting element P41 is clamped between the first inner wall surface P331 of the linking unit P3 and the inner wall surface of the seat element P10 on both sides, and cannot move or move.

When the linkage unit P3 is located at the second position, the linkage unit P3 can drive the connecting element P41 to displace through the third inner wall surface P333, so as to drive the braking body P40 to move away from the first movable unit P2, and a gap exists between the limiting portion P400 of the braking body P40 and the engaging portion P20 of the first movable unit P2; also, the second slot region P321 of the interlocking unit P3 may provide a space and a margin for the connecting element P41 to move and displace in the movable slot P101. At this time, the user can adjust the tilting angle of the first movable unit P2.

Further, the braking body P40 may have a limiting groove P402, the braking unit P4 may further include a fixing element P42, and the fixing element P42 is disposed through the limiting groove P402 and connected to the fixing unit P1. In addition, the braking unit P4 may further include a second elastic member P43, and the second elastic member P43 is connected to the fixing unit P1 and the braking body P40.

For example, in conjunction with fig. 5-9, the limiting groove P402 may be an oblong shape, and the fastening element P42 may be a screw or other type of fastening element, but not limited thereto. Therefore, the positioning module P of the present invention has the limiting groove P402 and the fixing element P42 to improve the stability of the brake unit P4 during movement and displacement.

Also, the second elastic member P43 may be a spring, a tension spring, or other elastic member. One end of the second elastic member P43 is detachably connected to the seat member P10, and the other end of the second elastic member P43 is detachably connected to the stopper body P40 of the stopper unit P4. Therefore, when the positioning module P is in the adjustment state, the user can press and touch the connecting element P41, so that the connecting element P41 drives the braking body P40 to move away from the first movable unit P2, and the limiting portion P400 of the braking body P40 is driven to disengage from the engaging portion P20 of the first movable unit P2; at this time, the second elastic member P43 is in a stretched state.

Next, when the user does not apply force to the connecting element P4, the second elastic element P43 can drive the braking body P40 to move toward the first movable unit P2 by its own elastic contraction force, so that the limiting portion P400 of the braking body P40 is engaged with the engaging portion P20 of the first movable unit P2; at this time, the second elastic member P43 is in a contracted state.

Therefore, the positioning module P of the present invention provides the brake body P40 with an automatic reset function by providing the second elastic element P43.

Therefore, when the interlocking unit P3 is located at the first position, the engaging portion P30 is away from the positioning portion P100, and the interlocking unit P3 urges the stopper unit P4 to the positioned state, so that the restricting portion P400 of the stopper unit P4 is detachably engaged with the engaging portion P20. The positioning module P is located at the first position through the linking unit P3 to drive the rack module 3 to be in a fixed state. For example, as shown in fig. 1 to 12, when the linking unit P3 is located at the first position, the positioning module P is in the shape-stabilized state, and at this time, the first movable unit P2 is restricted from being movable and rotatable. Therefore, the rack module 3 is fixed and cannot move.

Conversely, when the linkage unit P3 is located at the second position, the restriction part P400 is detachably connected to the positioning part P100, and the linkage unit P3 drives the stopper unit P4 to be in the active state, so that the restriction part P400 of the stopper unit P4 engages or disengages from the engaging part P20; when the restriction portion P400 is disengaged from the engagement portion P20, the rack module 3 is in an unfixed state. For example, as shown in fig. 1 to 12, when the linking unit P3 is located at the second position, the positioning module P can be in an adjustment state; at this time, the first activity unit P2 is in an adjustable state. Therefore, the user adjusts the position and angle of the board frame module 3.

When the user completes the adjustment of the position and angle of the rack module 3, the user can push the pressing part P31 to disengage the engaging part P30 from the positioning part P100; at this time, the first elastic element P11 can drive the linking unit P3 to move from the second position to the first position by its own elastic contraction force; at this time, there is still a certain gap between the limiting part P400 and the concave part P201, so that when the user starts to operate or use the screen, the first movable unit P2 is indirectly applied with force, and the braking unit P4 and the linking unit P3 are also driven by the elastic restoring force of the first elastic element P11, so that the limiting part P400 and the concave part P201 continuously reduce the gap until the gap disappears, and the first movable unit P2 is driven to be completely fixed by the braking unit P4 and can not be displaced. Then, the positioning module P is changed from the adjustment state to the shaping state, and the first movable unit P2 is restricted from moving and rotating.

It should be noted that, in other preferred embodiments, the structure of the supporting module 2 of this embodiment may also be the same as the positioning module P, i.e. the rack device Z of the present invention may be provided with two positioning modules P.

In addition, the supporting module 2, the positioning module P or the plate frame module 3 of the present embodiment may further include a fixing element and a linking element (not shown) such as a torsion spring, a bolt, a nut, etc.

However, the above-mentioned example is only one of the possible embodiments and is not intended to limit the present invention.
