Description

Technical Field

[0001] This utility model relates to the field of keyboard positioning structures, and more specifically to a positioning device. 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 be rotated and adjusted at multiple angles relative to the keyboard, thus enabling flexible adjustment of the tablet's support angle.

[0003] In existing keyboard designs, a spring-loaded locking mechanism is commonly used to position the dial and prevent it from wobbling after it has rotated to its designated position. However, in current keyboard designs, the spring-loaded locking mechanism only operates in the state of engaging with the dial; users cannot switch it to a state where it is detached from the dial and back to engaging with it as needed, thus failing to meet diverse usage requirements.

[0004] To address these issues, some companies have recently developed new positioning devices. While these devices can switch between the elastic locking device and the turntable in either a separated or engaged state, their structure is complex, their manufacturing cost is high, and their switching operation is cumbersome, falling far short of meeting the industry's high requirements.

Detailed Implementation

[0018] 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.

[0019] like Figure 1-4As shown, a positioning device includes a support member 10, a turntable 20, a toggle block 50, and an elastic locking device 70. The turntable 20 is rotatably mounted on the support member 10. The toggle block 50 is movably mounted on the support member 10 and can move between a first position and a second position. The elastic locking device 70 is mounted on the toggle block 50. When the toggle block 50 is in the first position, the elastic locking device 70 engages with the turntable 20. When the toggle block 50 is in the second position, the elastic locking device 70 disengages from the turntable 20. The elastic locking device 70 includes a locking mechanism. The locking block 30 and the spring; the locking block 30 is movably mounted on the actuating block 50, and the turntable 20 has a plurality of turntable positioning structures 21 arranged circumferentially on it; the turntable 20 forms a stop portion 22 between any two adjacent turntable positioning structures 21 for the locking block 30 to abut against; the locking block 30 is used to engage with the turntable positioning structure 21 and makes a sound when engaged with the turntable positioning structure 21, and the spring is disposed between the locking block 30 and the actuating block 50; when the actuating block 50 is in the first position, the spring is used to provide an elastic force to push the locking block 30 toward the turntable 20.

[0020] In use, when the user pushes the toggle block 50 to the first position, the elastic locking device 70 is engaged with the turntable 20. When the turntable 20 rotates under the user's pushing force, the locking block 30 abuts against the turntable 20 under the elastic force of the spring. As the turntable 20 rotates, the locking block 30 sequentially engages with the corresponding turntable positioning structure 21 and makes a sound, making it easy for the user to clearly perceive the positioning operation. After the turntable 20 rotates to the correct position, the locking block 30 engages with the corresponding turntable positioning structure 21. The engagement of the locking block engagement structure 31 with the corresponding turntable positioning structure 21 can position the turntable 20 and prevent the turntable 20 from shaking randomly. By moving the toggle block 50 to the second position, the locking block 30 is separated from the turntable 20, thus removing the locking effect of the locking block 30 on the turntable 20. This also prevents noise caused by the locking block 30 colliding with the turntable 20 when it is rotated. Therefore, the positioning device provided by this utility model combines the support member 10, the turntable 20, the toggle block 50, and the elastic locking device 70. The elastic locking device 70 is mounted on the toggle block 50, which is movable between the first and second positions. By moving the toggle block 50 to the second or first position, the elastic locking device 70 can be switched to a state of separation or engagement with the turntable 20. This makes the switching operation simple, convenient, and easy to use. Moreover, the structure is simple, assembly is convenient, and manufacturing costs are reduced.

[0021] The actuating block 50 is provided with a mounting cavity 33, and the locking block 30 is movably mounted within the mounting cavity 33 of the actuating block 50; the spring is disposed between the locking block 30 and the cavity wall of the mounting cavity 33. This structure facilitates the installation of the actuating block 50. Specifically, the locking block 30 is provided with an elastic element groove 32, and one end of the spring is mounted within the elastic element groove 32 to improve the stability of the spring installation.

[0022] The locking block 30 has a locking block engaging structure 31 at one end near the turntable 20 for engaging with the turntable positioning structure 21. One of the turntable positioning structure 21 and the locking block engaging structure 31 is an engaging groove, and the other is an engaging tooth for engaging with the engaging groove. That is, if the turntable positioning structure 21 is an engaging groove, then the locking block engaging structure 31 is an engaging tooth engaging with the engaging groove; if the turntable positioning structure 21 is an engaging tooth, then the locking block engaging structure 31 is an engaging groove.

[0023] In this embodiment, the turntable positioning structure 21 is an insert groove, and the locking block engaging structure 31 is an inserting protrusion that engages with the insert groove. The abutment part 22 is a spaced protrusion that protrudes relative to the insert groove. When the turntable 20 rotates under the user's pushing force, the inserting protrusion passes over the corresponding spaced protrusion as the turntable 20 rotates and enters the insert groove under the elastic force of the spring. When the inserting protrusion enters each insert groove from the spaced protrusion, it can collide and make a sound. When the turntable 20 rotates to the correct position, the inserting protrusion is inserted into the corresponding insert groove.

[0024] The actuating block 50 is provided with a pressure plate 62, which is used to press against the turntable 20. The pressure plate 62 can be used to press against the turntable 20 and to position the turntable 20.

[0025] The actuating block 50 is provided with a mounting post, and the pressure plate 62 is fitted onto the mounting post to facilitate the installation of the pressure plate 62.

[0026] The actuating block 50 is provided with an elastic positioning component 51, and the supporting member 10 is provided with a first fixed-position engagement structure 80 and a second fixed-position engagement structure 90. When the elastic positioning component 51 is engaged with the first fixed-position engagement structure 80, the actuating block 50 is held in the first position; when the elastic positioning component 51 is engaged with the second fixed-position engagement structure 90, the actuating block 50 is held in the second position. Through the engagement of the elastic positioning component 51 with the first fixed-position engagement structure 80 and the second fixed-position engagement structure 90, it is ensured that the actuating block 50 can be stably locked in the first or second position, avoiding accidental displacement of the actuating block 50 due to shaking or accidental contact, thus improving the reliability and stability of the elastic locking device 70 in the separated and engaged states of the turntable 20.

[0027] The elastic positioning component 51 includes a first elastic piece 55 and a second elastic piece 56. The first elastic piece 55 is disposed on one side of the actuating block 50, and the second elastic piece 56 is disposed on the other side of the actuating block 50. The first elastic piece 55 is provided with a first protrusion 53, and the second elastic piece 56 is provided with a second protrusion 54. The first positioning and fitting structure 80 includes a first positioning groove 81 and a second positioning groove 82. The first positioning groove 81 is used for engaging the first protrusion 53, and the second positioning groove 82 is used for engaging the second protrusion 54. The second positioning and fitting structure 90 includes a third positioning groove 91 and a fourth positioning groove 92. The third positioning groove 91 is used for engaging the first protrusion 53, and the fourth positioning groove 92 is used for engaging the second protrusion 54. By adopting the above structure for the elastic positioning component 51, the first positioning and fitting structure 80, and the second positioning and fitting structure 90, it is convenient to engage and fit, and also convenient to process and install.

[0028] Specifically, the two ends of the first elastic piece 55 are fixed to one side of the actuating block 50, and the first protrusion 53 protrudes outward relative to the actuating block 50. The two ends of the second elastic piece 56 are fixed to the other side of the actuating block 50, and the second protrusion 54 protrudes outward relative to the actuating block 50. Two first fixing grooves are provided on one side of the actuating block 50, and the two ends of the first elastic piece 55 are respectively fixed in the first fixing grooves. Two second fixing grooves are provided on the other side of the actuating block 50, and the two ends of the second elastic piece 56 are respectively fixed in the second fixing grooves.

[0029] The supporting member 10 is provided with a movable cavity 11, and the actuating block 50 is movably installed in the movable cavity 11. The first positioning groove 81 and the second positioning groove 82 are respectively provided on the two opposite inner sidewalls of the movable cavity 11. The third positioning groove 91 and the fourth positioning groove 92 are respectively provided on the two opposite inner sidewalls of the movable cavity 11. By adopting the above structure, the movable cavity 11 provides a guiding space for the movement of the actuating block 50, preventing the actuating block 50 from shifting. At the same time, by providing the first positioning groove 81 and the second positioning groove 82 on the two opposite inner sidewalls of the movable cavity 11, and by providing the third positioning groove 91 and the fourth positioning groove 92 on the two opposite inner sidewalls of the movable cavity 11, as the actuating block 50 moves to the position corresponding to the first fixed-positioning structure 80 or the second fixed-positioning structure 90, it is convenient for the elastic positioning member 51 to engage with the first fixed-positioning structure 80 or the second fixed-positioning structure 90.
