Description

Technical Field

[0001] This utility model relates to the field of keyboard devices, specifically to a positioning device with controllable sound feedback. Background Technology

[0002] Existing keyboard devices often have a turntable rotatably mounted on the keyboard, which is connected to a tablet cover via the turntable. This allows the tablet cover, along with the turntable, to rotate relative to the keyboard, thereby adjusting the angle of the tablet cover relative to the keyboard.

[0003] The existing turntable uses a positioning device for positioning. The existing positioning devices are divided into two categories: one type has sound feedback during positioning; the other type does not have sound feedback during positioning. However, the usage mode is relatively simple. Regardless of the type of existing positioning device, it is not possible to switch to positioning with sound feedback or positioning without sound feedback according to the user's needs during positioning, which is not convenient for flexible use. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide a positioning device with controllable sound feedback, which can be switched to positioning sound feedback mode or positioning silent feedback mode, so as to meet more user needs and facilitate flexible use.

[0005] The objective of this utility model is achieved through the following technical solution: A sound-feedback controllable positioning device includes a support member, a turntable, a sound-emitting locking block, a silent locking block, a pushing member, a first elastic member, and a second elastic member. The turntable is rotatably mounted on the support member. The turntable has multiple turntable positioning structures arranged circumferentially around its central axis. The sound-emitting locking block is movably mounted on the support member, and one end of the sound-emitting locking block near the turntable has a locking block engaging structure for fitting into the turntable positioning structure. The first elastic member is disposed between the sound-emitting locking block and the support member, and the first elastic member... The first elastic element provides an elastic force to move the sound-emitting locking block toward the turntable so that the locking block engagement structure engages with the turntable positioning structure and produces a sound; the second elastic element is movably mounted on the support member and is used to abut against the turntable for damping engagement with the turntable; the third elastic element is disposed between the silent locking block and the support member and provides an elastic force to move the silent locking block toward the turntable; the fourth elastic element is movably mounted on the support member and is used to push the sound-emitting locking block or separate the silent locking block from the turntable.

[0006] The pushing member is movably mounted on the support member and can move between a first position and a second position; when the pushing member is in the first position, the pushing member pushes the sound-emitting locking block to separate from the turntable; when the pushing member is in the second position, the pushing member pushes the silent locking block to separate from the turntable.

[0007] The pushing member is provided with a pushing member positioning and fitting structure, and the supporting member is provided with a first fixed-position fitting structure and a second fixed-position fitting structure; when the pushing member positioning and fitting structure is engaged with the first fixed-position fitting structure, the pushing member is held in a first position; when the pushing member positioning and fitting structure is engaged with the second fixed-position fitting structure, the pushing member is held in a second position.

[0008] The pushing member includes two elastic arms arranged opposite each other. The positioning and fitting structure of the pushing member includes a first embedding protrusion and a second embedding protrusion. The first embedding protrusion is disposed on one of the elastic arms, and the second embedding protrusion is disposed on the other elastic arm. The first positioning and fitting structure includes a first positioning groove and a second positioning groove. The first positioning groove is used for engaging the first embedding protrusion, and the second positioning groove is used for engaging the second embedding protrusion. The second positioning and fitting structure includes a third positioning groove and a fourth positioning groove. The third positioning groove is used for engaging the first embedding protrusion, and the fourth positioning groove is used for engaging the second embedding protrusion.

[0009] The supporting member is provided with a movable cavity, and the pushing member is movably installed in the movable cavity; the first positioning groove and the second positioning groove are respectively provided on the two opposite inner sidewalls of the movable cavity; the third positioning groove and the fourth positioning groove are respectively provided on the two opposite inner sidewalls of the movable cavity.

[0010] One of the turntable positioning structure and the locking block cooperation structure is an embedding groove, and the other is an embedding protrusion that is embedded and cooperates with the embedding groove.

[0011] The turntable positioning structure is an embedded groove, and the locking block mating structure is an embedded protrusion that is embedded and mated with the embedded groove.

[0012] A spacer protrusion is provided between any two adjacent embedding slots.

[0013] Both the first elastic element and the second elastic element are springs.

[0014] The end of the pusher away from the turntable is provided with a push protrusion; when the pusher moves to the point where the push protrusion is directly opposite the sound-emitting lock block, the push protrusion pushes the sound-emitting lock block away from the turntable; when the pusher moves to the point where the push protrusion is directly opposite the silent lock block, the push protrusion pushes the silent lock block away from the turntable.

It combines a support component, a turntable, a sound-emitting locking block, a silent locking block, a pushing component, a first elastic component, and a second elastic component. The pushing component can separate the silent locking block from the turntable, allowing the turntable to be positioned by the sound-emitting locking block in conjunction with the turntable. Alternatively, the pushing component can also separate the sound-emitting locking block from the turntable, allowing the turntable to be positioned by the silent locking block in conjunction with the turntable. This allows switching between positioning sound feedback and positioning silent feedback modes. The sound feedback mode provides clear audio feedback for positioning operations, while the silent feedback mode satisfies the need for quiet operation, meeting various user needs and offering flexible use. Furthermore, it is convenient and quick to install, saving installation time. Attached Figure Description

Detailed Implementation

[0017] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0018] like Figure 1-4As shown, a positioning device with controllable sound feedback includes a support member 10, a turntable 20, a sound-emitting locking block 30, a silent locking block 40, a pushing member 50, a first elastic member, and a second elastic member. The turntable 20 is rotatably mounted on the support member 10. The turntable 20 is provided with a plurality of turntable positioning structures 21 arranged circumferentially around its central axis. The sound-emitting locking block 30 is movably mounted on the support member 10, and one end of the sound-emitting locking block 30 near the turntable 20 is provided with a locking block engaging structure 31 for engaging with the turntable positioning structure 21. The first elastic member is disposed between the sound-emitting locking block 30 and the support member 10, and the first... The elastic element provides an elastic force to cause the sound-emitting locking block 30 to move toward the turntable 20 so that the locking block engaging structure 31 engages with the turntable positioning structure 21 and produces a sound; the silent locking block 40 is movably mounted on the support member 10 and is used to abut against the turntable 20 for damping engagement with the turntable 20; the second elastic element is disposed between the silent locking block 40 and the support member 10, and the second elastic element provides an elastic force to cause the silent locking block 40 to move toward the turntable 20; the pushing member 50 is movably mounted on the support member 10; the pushing member 50 is used to push the sound-emitting locking block 30 or the silent locking block 40 to separate from the turntable 20.

[0019] In use, the user pushes the pusher 50, which pushes the silent locking block 40 to separate it from the turntable 20. When the turntable 20 rotates under the user's push, the sound-emitting locking block 30 moves against the turntable 20 under the elastic force of the first elastic element. As the turntable 20 rotates, the locking block engaging structure 31 engages with the corresponding turntable positioning structure 21 in sequence and makes a sound, which makes it easy for the user to clearly perceive the positioning operation. After the turntable 20 rotates to the correct position, the locking block engaging structure 31 engages with the corresponding turntable positioning structure 21. The engagement of the locking block engaging structure 31 with the corresponding turntable positioning structure 21 can position the turntable 20 and prevent the turntable 20 from shaking randomly. The user pushes the pusher 50 to separate the sound-emitting locking block 30 from the turntable 20. When the turntable 20 rotates into position under the user's push, the silent locking block 40 abuts against the turntable 20 under the elastic force of the second elastic element. The silent locking block 40 abuts against the turntable 20 and cooperates with the damping of the turntable 20 to position the turntable 20, preventing the turntable 20 from shaking randomly. This provides a silent damping function, meeting the needs of silent adjustment in quiet scenarios. Therefore, the positioning device with controllable sound feedback provided by this utility model, which uses the support member 10, the turntable 20, and the sound-emitting locking block, provides a sound-emitting locking block. The combination of the silent locking block 40, the pushing component 50, the first elastic component, and the second elastic component allows the silent locking block 40 or the audible locking block 30 to be separated from the turntable 20 by pushing the pushing component 50. The audible locking block 30, the silent locking block 40, and the turntable 20 are positioned in coordination with the turntable 20. This allows switching between positioning audible feedback mode and positioning silent feedback mode. The positioning audible feedback mode provides clear sound feedback for positioning operation, while the positioning silent feedback mode meets the silent adjustment requirements of quiet scenarios, satisfying more user needs and facilitating flexible use.

[0020] The pushing member 50 is movably mounted on the support member 10 and can move between a first position and a second position. When the pushing member 50 is in the first position, it pushes the sound-emitting locking block 30 to separate from the turntable 20. When the pushing member 50 is in the second position, it pushes the silent locking block 40 to separate from the turntable 20. In use, the user can push the pushing member 50 to the first position to separate the sound-emitting locking block 30 from the turntable 20, and the silent locking block 40 cooperates with the turntable 20 to position the turntable 20. Similarly, by pushing the pushing member 50 to the second position, the user can push the silent locking block 40 to separate from the turntable 20, and the sound-emitting locking block 30 cooperates with the turntable 20 to position the turntable 20, making it convenient to use.

[0021] The pushing member 50 is provided with a pushing member positioning and engaging structure 51, and the supporting member 10 is provided with a first fixed-position engaging structure 80 and a second fixed-position engaging structure 81. When the pushing member positioning and engaging structure 51 is engaged with the first fixed-position engaging structure 80, the pushing member 50 is held in a first position; when the pushing member positioning and engaging structure 51 is engaged with the second fixed-position engaging structure 81, the pushing member 50 is held in a second position. Through the engagement of the pushing member positioning and engaging structure 51 with the first fixed-position engaging structure 80 and the second fixed-position engaging structure 81, it is ensured that the pushing member 50 can be stably locked in the first or second position, avoiding accidental displacement of the pushing member 50 due to shaking or accidental contact, thus improving the reliability and stability of the positioning device in different modes.

[0022] The pushing member 50 includes two elastic arms 52 arranged opposite to each other. The pushing member positioning and mating structure 51 includes a first embedding protrusion 53 and a second embedding protrusion 54. The first embedding protrusion 53 is disposed on one of the elastic arms 52, and the second embedding protrusion 54 is disposed on the other elastic arm 52. The first positioning and mating structure 80 includes a first positioning groove 91 and a second positioning groove 92. The first positioning groove 91 is used for engaging the first embedding protrusion 53, and the second positioning groove 92 is used for engaging the second embedding protrusion 54. The second positioning and mating structure 81 includes a third positioning groove 93 and a fourth positioning groove 94. The third positioning groove 93 is used for engaging the first embedding protrusion 53, and the fourth positioning groove 94 is used for engaging the second embedding protrusion 54. By adopting the above structure for the pushing member positioning and mating structure 51, the first positioning and mating structure 80, and the second positioning and mating structure 81, it is convenient to engage and mat, and also convenient to process and install.

[0023] The supporting member 10 is provided with a movable cavity 90, and the pushing member 50 is movably installed in the movable cavity 90. The first positioning groove 91 and the second positioning groove 92 are respectively provided on the two opposite inner sidewalls of the movable cavity 90. The third positioning groove 93 and the fourth positioning groove 94 are respectively provided on the two opposite inner sidewalls of the movable cavity 90. By adopting the above structure, the movable cavity 90 provides a guiding space for the movement of the pushing member 50, avoiding the pushing member 50 from shifting. At the same time, by providing the first positioning groove 91 and the second positioning groove 92 on the two opposite inner sidewalls of the movable cavity 90, and by providing the third positioning groove 93 and the fourth positioning groove 94 on the two opposite inner sidewalls of the movable cavity 90, as the pushing member 50 moves to the position corresponding to the first fixed-positioning structure 80 or the second fixed-positioning structure 81, it is convenient for the pushing member positioning structure 51 to engage with the first fixed-positioning structure 80 or the second fixed-positioning structure 81.

[0024] One of the turntable positioning structure 21 and the locking block cooperating structure 31 is an insert groove, and the other is an inserting protrusion that engages with the insert groove. That is, if the turntable positioning structure 21 is set as an insert groove, then the locking block cooperating structure 31 is set as an inserting protrusion that engages with the insert groove; if the turntable positioning structure 21 is set as an inserting protrusion, then the locking block cooperating structure 31 is set as an insert groove.

[0025] In this embodiment, the turntable positioning structure 21 is an inserting groove, and the locking block engaging structure 31 is an inserting protrusion that engages with the inserting groove. A spacer protrusion 120 is provided between any two adjacent inserting grooves. As the turntable 20 rotates under the user's pushing force, the inserting protrusion passes over the corresponding spacer protrusion 120 and enters the inserting groove under the elastic force of the first elastic element. The inserting protrusion can collide and produce a sound when it enters each inserting groove from the spacer protrusion 120. When the turntable 20 rotates to its final position, the inserting protrusion is embedded in the corresponding inserting groove.

[0026] In this embodiment, both the first elastic element and the second elastic element are springs. Of course, in addition to these, the first elastic element and the second elastic element can be any existing elastic element, as long as it can provide the corresponding elastic force.

[0027] In this embodiment, the sound-emitting lock block 30 is provided with a sound-emitting spring groove 32, and the end of the first elastic member near the sound-emitting lock block 30 is installed in the sound-emitting spring groove 32. The silent lock block 40 is provided with a silent spring groove 41, and the end of the second elastic member near the silent lock block 40 is installed in the silent spring groove 41, so as to improve the stability of the installation of the first elastic member and the second elastic member.

[0028] The pusher 50 is provided with a push protrusion 55 at the end away from the turntable 20. When the pusher 50 moves to the point where the push protrusion 55 is directly opposite the sound-emitting lock block 30, the push protrusion 55 pushes the sound-emitting lock block 30 away from the turntable 20, and the push protrusion 55 can be used to push the sound-emitting lock block 30 away from the turntable 20. When the pusher 50 moves to the point where the push protrusion 55 is directly opposite the silent lock block 40, the push protrusion 55 pushes the silent lock block 40 away from the turntable 20, and the push protrusion 55 can be used to push the silent lock block 40 away from the turntable 20.

[0029] As a preferred embodiment of the present invention, from the end of the push protrusion 55 to the middle of the push protrusion 55, the push protrusion 55 can be configured to gradually protrude in a direction away from the turntable 20, so that as the push member 50 moves, the push protrusion 55 can gradually push the sound-emitting lock block 30 or the silent lock block 40 away from the turntable 20.

[0030] The pushing member 50 also includes a pushing body, on which the two elastic arms 52 are disposed, and the pushing protrusion 55 is disposed on the pushing body. The pushing body is elongated to facilitate processing.

[0031] In this embodiment, the positioning device may employ two silent locking blocks 40; each silent locking block 40 is provided with a second elastic element between it and the supporting member 10; the pushing member 50 is provided with two pushing protrusions 55; when the pushing member 50 moves to the point where the pushing protrusions 55 are directly opposite the silent locking blocks 40, the two pushing protrusions 55 respectively push the two silent locking blocks 40 in a direction away from the turntable 20.

[0032] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
