[0001] This invention relates to the field of rotating devices, and more specifically to a rotating device and a keyboard protective shell assembly. Background Technology

[0002] Keyboard protective cases are mobile device accessories that integrate a keyboard and a protective case. The protective case can fix electronic products such as tablets or mobile phones to protect them, while the physical keyboard provides clear typing feedback and higher typing speed and accuracy. This greatly facilitates scenarios that require a lot of text input, such as document processing, email composition, and programming, and is widely used in mobile office and learning scenarios.

[0003] The rotating mechanism, an important component of the keyboard protective case, is used to adjust the position of the case. However, during use, after the rotation is completed, displacement and cable tangling can easily occur, affecting the user experience. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a rotating device that can ensure stable locking and avoid displacement, and can achieve electrical conduction between the first electrical connection module and the second electrical connection module while avoiding wire entanglement, thereby improving the reliability of use.

[0005] The second objective of this invention is to provide a keyboard protective shell assembly that employs the aforementioned rotating device. This ensures stable locking and prevents displacement. While achieving electrical connection between the first and second electrical connection modules, it also avoids wire tangling, thereby improving reliability.

[0006] One of the objectives of this invention is achieved through the following technical solution:

[0012] The first component is provided with an annular groove, and the annular conductive ring is embedded in the annular groove.

[0013] The first electrical connection module also includes a pull-out interface; the pull-out interface is used for electrical connection with the annular conductive coil.

[0036] The present invention will now be further described in conjunction with 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.

[0037] like Figure 1-6 As shown, a rotating device includes a second component 10, a first component 40, and a positioning device 50; the first component 40 and the second component 10 are rotatably connected, such that the first component 40 and the second component 10 can rotate relative to each other about a first rotation axis T; the positioning device 50 is used to lock the first component 40 relative to the second component 10.

[0038] The second component 10 has a plurality of alternating grooves 31 and protrusions 32 arranged around the first rotation axis T; the positioning device 50 includes a positioning element 51 and an elastic reset element; the positioning element 51 is provided with a positioning end 52 for being embedded in the groove 31, and the positioning element 51 is movably engaged with the first component 40; the elastic reset element is disposed between the positioning element 51 and the first component 40, and the elastic reset element is used to provide an elastic force to cause the positioning end 52 to be embedded in the groove 31.

[0039] In use, when the user rotates the first component 40 relative to the second component 10, the positioning member 51, which is movably fitted on the first component 40, will rotate accordingly. Its positioning end 52 will slide past the protrusion 32 of the second component 10 and reach a groove 31. Under the pushing force of the elastic reset element, the positioning member 51 moves towards the groove 31, causing the positioning end 52 to automatically embed into the groove 31. As the first component 40 continues to rotate, the positioning member 51 overcomes the spring force and slides out of the groove 31, passing the next protrusion 32 and embedding into the next groove 31. This process continues until the first component 40 is fully rotated, and the positioning end 52 of the positioning member 51 is embedded in the corresponding groove 31, locking the first component 40 in the corresponding position. By adopting the above structure for the positioning device 50, the stability of the locking is ensured, preventing the position of the first component 40 from changing due to slight external forces during use, and facilitating assembly and manufacturing.

[0040] The first component 40 is provided with a first electrical connection module 93, and the second component 10 is provided with a second electrical connection module 92; the first electrical connection module 93 and the second electrical connection module 92 are electrically connected, which can realize the transmission of electrical energy between the first electrical connection module 93 and the second electrical connection module 92.

[0041] The first electrical connection module 93 and the second electrical connection module 92 can be existing electrical connection modules such as conductive wires or circuits. In a preferred embodiment of the present invention, the first electrical connection module 93 includes a first conductive element 41, and the second electrical connection module 92 includes a second conductive element 11; the first conductive element 41 and the second conductive element 11 are in sliding contact, and the extension trajectory of either the first conductive element 41 or the second conductive element 11 is a circle with the first rotation axis T as its central axis. When the first component 40 is rotated relative to the second component 10, the first conductive element 41 moves with the first component 40 and slides in contact with the second conductive element 11, maintaining electrical conductivity. By adopting the above structure, while the first component 40 can be rotated relative to the second component 10 to adjust its position, the sliding contact between the first conductive element 41 and the second conductive element 11 maintains electrical conductivity between the first electrical connection module 93 and the second electrical connection module 92, avoiding wire tangling and improving reliability.

[0042] One of the first conductive element 41 and the second conductive element 11 is an annular conductive ring, and the other is a conductive contact; that is, if the first conductive element 41 is set as an annular conductive ring, then the second conductive element 11 is a conductive contact; if the first conductive element 41 is set as a conductive contact, then the second conductive element 11 is an annular conductive ring. The central axis of the annular conductive ring is consistent with the first rotation axis T, that is, the extension trajectory of the annular conductive ring is a circle with the first rotation axis T as its central axis. During the process of the user rotating the first component 40 to adjust the position of the first component 40 relative to the second component 10, the annular conductive ring rotates with the first component 40 and contacts the conductive contact through the corresponding area, so that the annular conductive ring and the conductive contact can maintain contact within a 360° rotation range. Thus, the annular conductive ring is in contact with the conductive contact in all directions of rotation of the first component 40 relative to the second component 10, ensuring electrical conduction of the first electrical connection module 93 and the second electrical connection module 92, improving the stability of use, facilitating processing, and reducing manufacturing costs.

[0043] In a preferred embodiment of the present invention, the first component 40 is provided with an annular groove 17, and the annular conductive ring is embedded in the annular groove 17. By adopting the above structure, the installation of the annular conductive ring can be facilitated.

[0044] In a preferred embodiment of the present invention, the first electrical connection module 93 further includes a pull-out interface 12; the pull-out interface 12 is used for electrical connection with the annular conductive ring. In use, the electronic product can be fixed on the first component 40, and the pull-out interface 12 is used to connect with the electronic product fixed on the first component 40, so that the electronic product is electrically connected to the second electrical connection module 92 through the first electrical connection module 93. The pull-out interface 12 can also be pushed in and pulled out from the first component 40 according to the usage requirements, which facilitates the connection and separation of the electronic product and the pull-out interface 12.

[0045] To further improve ease of use, it is also possible to... Figure 11 As shown, a charging connection part 13 is also provided on the first component 40. The charging connection part 13 can be a magnetic charging connector, wherein the magnetic charging connector can include a male connector and a female connector. One of the male connector and the female connector is fixed on the first component 40, and the other is used to connect to an external power source. The male connector and the female connector are electrically connected by magnetic attraction, which is convenient for use.

[0046] Of course, in addition to the above, the charging connection part 13 can also be a magnetic charging connector, or as... Figure 12 As shown, a charging interface 98 or other charging connectors available on the market can be used, as long as they can be used to charge electronic products.

[0047] The protrusion 32 near the first rotation axis T forms a crest 33. The crest 33 is provided with a first arc surface convex outward toward the first rotation axis, and both sides of the first arc surface are provided with guide inclined surfaces 34. Along the direction away from the first arc surface, the distance between the guide inclined surfaces 34 on both sides of the first arc surface gradually increases. A groove 31 is formed between the guide inclined surfaces 34 of any two adjacent protrusions 32. When the user rotates the first component 40 relative to the second component 10, the positioning component 51 can be smoothly guided from the groove 31 to the adjacent protrusion 32 or from the protrusion 32 to the adjacent groove 31 through the guide inclined surfaces 34, which can improve the smoothness of the positioning component 51 entering and exiting the groove 31.

[0048] The positioning element 51 may be a positioning post, with the end of the positioning post away from the first rotation axis forming a positioning end 52 and having a spherical surface. The sound generated when the positioning end 52 of the positioning post collides with the groove wall of the groove 31 during the process of being inserted into the groove allows the user to perceive the adjustment and locking process of the orientation of the first component 40.

[0049] The first component 40 includes a housing 14 and a mating seat 15. The mating seat 15 is fixed to the housing 14 and includes an insert 16. The second component 10 is fitted over the insert 16. In use, the housing 14 can be fitted onto electronic products such as tablet computers. By combining the housing 14 and the mating seat 15 with the first component 40, and fitting the second component 10 over the insert 16, the first component 40 can rotate relative to the second component 10, while also facilitating manufacturing and assembly.

[0050] The insert 16 has a mounting cavity 18, and the positioning member 51 is movably mounted in the mounting cavity 18. One end of the elastic reset element abuts against the positioning member 51, and the other end abuts against the cavity wall of the mounting cavity 18. By adopting the above structure, the installation of the elastic reset element can be facilitated.

[0051] The elastic reset element can be an elastic element such as an elastic sheet. In a preferred embodiment of the present invention, the elastic reset element includes a spring, which is located in the mounting cavity 18. One end of the spring abuts against the positioning member 51, and the other end abuts against the cavity wall of the mounting cavity 18.

[0052] The mating seat 15 also includes a cover 19, and the insert 16 is disposed on the cover 19; the second component 10 is at least partially sandwiched between the housing 14 and the cover 19. By adopting the above structure, the stability of the installation between the first component 40 and the second component 10 can be ensured, and the reliability and durability of use can be improved.

[0053] The housing 14 is provided with a mounting hole 62; the insert 16 is provided with an outwardly protruding mounting post 61, which is inserted into the mounting hole 62. The cooperation between the mounting post 61 and the mounting hole 62 ensures the accuracy of the installation and positioning between the housing 14 and the mating seat 15.

[0054] Specifically, the housing 14 is also provided with a stepped groove communicating with the mounting hole 62. The housing 14 is fixedly connected to the mating seat 15 by screws. The mounting post 61 is provided with a threaded hole, and the screw passes through the stepped groove and is threadedly connected to the threaded hole. By adopting the above structure, the installation stability between the housing 14 and the mating seat 15 can be improved.

[0055] Of course, in addition to this, the sleeve 14 can also be fixedly connected to the mating seat 15 by means of pins or adhesive. However, connecting the sleeve 14 and the mating seat 15 in the above manner is the preferred embodiment of the present invention, which can improve the installation stability between the sleeve 14 and the mating seat 15.

[0056] The second component 10 includes a magnetic base 20 and a pivot base 30; the pivot base 30 is pivotally connected to the magnetic base 20; the first component 40 is rotatably connected to the pivot base 30. In use, the user can pivot the pivot base 30 relative to the magnetic base 20 around the first pivot axis P to different angles as needed, allowing the first component 40 to pivot with the pivot base 30 to adjust the pitch angle of the first component 40. The first component 40 can also be rotated relative to the pivot base 30 around the first rotation axis T to different positions. After the first component 40 is rotated to its final position, the positioning device 50 locks the first component 40 relative to the pivot base 30 to ensure the stability of the first component 40 after angle adjustment. Therefore, by adopting the above structure, the user can freely and flexibly adjust the pitch angle and rotation position of the first component 40 according to usage needs, further meeting more user requirements and improving the user experience.

[0057] Specifically, the second conductive element 11 is disposed on the pivot seat 30, and the first conductive element 41 is disposed on the housing 14. The pivot seat 30 is provided with a circular hole, and the groove 31 and the protrusion 32 are arranged alternately on the wall of the circular hole. The pivot seat 30 is sandwiched between the housing 14 and the cover 19.

[0058] like Figure 7-10 As shown, the present invention also discloses a keyboard protective case assembly, including a keyboard device 80, a base 70 and a protective case 1;

[0059] The base 70 is pivotally connected to the keyboard device 80; the base 70 is provided with a keyboard electrical connection module 95 that is electrically connected to the keyboard device 80;

[0060] The protective shell 1 is used to fix electronic products to it, and the protective shell 1 includes the rotating device; the first electrical connection module 93 is used to electrically connect with the electronic product; the protective shell 1 is used to magnetically connect with the base 70; when the protective shell 1 and the base 70 are magnetically connected, the second electrical connection module 92 and the keyboard electrical connection module 95 are electrically connected. Specifically, the first component 40 is used to fix electronic products to it.

[0061] In use, electronic products (such as tablets, mobile phones, etc.) can be fixed on the protective case 1. By magnetically connecting the protective case 1 to the base 70, the protective case 1 and the keyboard device 80 can be combined together. At this time, the second electrical connection module 92 and the keyboard electrical connection module 95 are electrically connected. The keyboard device 80 is electrically connected to the electronic product through the keyboard electrical connection module 95, the second electrical connection module 92, and the first electrical connection module 93, so that power can be transmitted between the electronic product and the keyboard device 80 (that is, power can be supplied between the keyboard device 80 and the electronic product). When watching movies or reading, the user can apply force to the protective case 1 to overcome the magnetic attraction and separate the protective case 1 from the base 70, thus separating the protective case 1 from the keyboard device 80 for independent use. The user can hold the protective case 1 with the electronic product installed while watching movies or reading. Due to its lighter weight and more portable shape, the entertainment and reading experience is more focused and burden-free. Moreover, during use, the user can pivot the base 70 relative to the keyboard device 80 around the second pivot axis Q to different angles according to usage needs, thereby flexibly adjusting the opening and closing angle of the protective case 1. After the keyboard protective case assembly is opened by rotating the base 70 relative to the keyboard device 80 about the second pivot axis Q in a direction away from the keyboard device 80, the pivot seat 30 of the protective case 1 magnetically connected to the base 70 can be pivoted relative to the magnetic seat 20 about the first pivot axis P to different angles according to usage needs. This allows the first component 40 to pivot with the pivot seat 30 to adjust the pitch angle of the first component 40. The first component 40 can also be rotated relative to the second component 10 about the first rotation axis T to different positions. For example, the first component 40 and the electronic product fixed on it can be rotated to a horizontal position. The first component 40 is rotated into position, and after it is in position, the positioning device 50 locks the first component 40 relative to the second component 10 to ensure the stability of the first component 40 after its position adjustment. Therefore, the floating rotating keyboard protective shell assembly provided by the present invention uses a keyboard device 80, a base 70, and a protective shell 1, with the base 70 pivotally connected to the keyboard device 80. At the same time, the protective shell 1 is used to magnetically connect to the base 70. In use, by magnetically connecting or separating the protective shell 1 from the base 70, the protective shell 1 and the keyboard device 80 can be connected. Whether combined or separated, they can be flexibly adapted to different usage scenarios, facilitating flexible use. Moreover, when the protective shell 1 is magnetically connected to the base 70, the second electrical connection module 92 and the keyboard electrical connection module 95 are electrically connected, eliminating the need for users to perform any additional manual plugging operations, further improving ease of use. Furthermore, users can freely and flexibly adjust the tilt angle and rotation position of the first component 40 according to their usage needs, satisfying more viewing angle requirements and improving the user experience.

[0062] The keyboard electrical connection module 95 can be an existing electrical connection module such as a conductive wire or circuit. As long as the second electrical connection module 92 and the keyboard electrical connection module 95 are electrically connected, the keyboard device 80 can be electrically connected to the first electrical connection module 93 through the keyboard electrical connection module 95, the second electrical connection module 92, and the first electrical connection module 93.

[0063] The second electrical connection module 92 further includes a first contact 96, which is electrically connected to the second conductive element 11. The first contact 96 and the second conductive element 11 can be directly electrically connected, or indirectly connected via cables or lines. The keyboard electrical connection module 95 includes a second contact 97; the contact or separation of the second contact 97 and the first contact 96 enables the electrical connection between the keyboard electrical connection module 95 and the second electrical connection module 92. When the protective shell 1 and the base 70 are magnetically connected, the first contact 96 and the second contact 97 contact each other, and the second electrical connection module 92 and the keyboard electrical connection module 95 are electrically connected. In use, the user magnetically connects the protective case 1 to the base 70, the first contact 96 and the second contact 97 make contact, and the second electrical connection module 92 is electrically connected to the keyboard electrical connection module 95. The keyboard device 80 is electrically connected to the electronic product through the keyboard electrical connection module 95, the second electrical connection module 92, and the first electrical connection module 93. Power can be transferred between the electronic product and the keyboard device 80. When the electronic product is connected to an external power source, power can be transferred from the electronic product to the keyboard device 80 to power the keyboard device 80. When the keyboard device 80 is connected to an external power source, power can be transferred from the keyboard device 80 to the electronic product to power the electronic product. When the user lifts the protective case 1 from the base 70, the first contact 96 and the second contact 97 separate, and the second electrical connection module 92 is electrically disconnected from the keyboard electrical connection module 95.

[0064] Specifically, the magnetic base 20 is used for magnetic connection with the base 70. The base 70 can pivot relative to the keyboard device 80 about a first pivot axis Q; the pivot base 30 can pivot relative to the magnetic base 20 about a first pivot axis P; the first pivot axis Q is parallel to the first pivot axis P.

[0065] The magnetic base 20 and the base 70 can be magnetically connected in various ways. For example, one of the magnetic base 20 and the base 70 can be made of magnet or at least partially made of magnet, and the other can be made of magnetically conductive metal (such as iron) for magnetic attraction with magnet; or both the magnetic base 20 and the base 70 can be made of magnet or at least partially made of magnet, and so on.

[0066] The base 70 is provided with a receiving area 71, which is used to accommodate at least part of the protective shell 1. Specifically, the receiving area 71 is used to accommodate part of the first component 40 and the magnetic base 20. When storing, the first component 40 together with the pivot base 30 is pivoted relative to the magnetic base 20 towards the base 70 so that part of the first component 40 is accommodated in the receiving area 71. The base 70 is also pivoted relative to the keyboard device 80 towards the keyboard device 80, so that the keyboard protective shell assembly is stacked. This makes the structure compact and the size small, which is convenient for storage and improves the portability of the overall assembly. Moreover, by accommodating part of the first component 40 in the receiving area 71, the stability of the protective shell 1 can be improved when storing or carrying it, and the shaking and collision of the protective shell 1 can be reduced.

[0067] The base 70 includes a base body 72 and a baffle 73; one end of the base body 72 is formed as a first end, and the other end is formed as a second end; the first end of the base body 72 is pivotally connected to the keyboard device 80, and the baffle 73 is disposed at the second end of the base body 72; the side W of the second end of the base body 72 near the keyboard device 80 protrudes relative to the baffle 73; the second end of the base body 72 and the baffle 73 form the receiving area 71. By adopting the above structure, the formation of the receiving area 71 can be facilitated, and the back of the magnetic base 20 can be abutted by the baffle 73, while the base body 72 can support and hold the magnetic base 20, thus forming an effective limit, enhancing the stability and fit of the protective case 1 when placed, and facilitating manufacturing.

[0068] When the magnetic base 20 is magnetically connected to the base 70, the second end of the base body 72 is used for the magnetic base 20 to abut against. When the magnetic base 20 and the base 70 are magnetically connected, the magnetic base 20 abuts against the second end of the base body 72. In use, the magnetic connection between the magnetic base 20 and the base 70, along with the support of the protective shell 1 by the second end of the base body 72, improves the stability of the protective shell 1 during installation. Furthermore, when the user applies force to overcome the magnetic attraction and lifts the protective shell 1 from the base 70, the protective shell 1 can be quickly separated from the base 70.

[0069] The keyboard device 80 can be any keyboard device available on the market, such as a mechanical keyboard or a membrane keyboard.

[0070] The base 70 can be pivotally connected to the keyboard device 80 using various existing structures, as long as the base 70 can pivot relative to the keyboard device 80 to different angles. For example, a pivot shaft 91 can be provided on the base 70, and a pivot hole can be provided on the keyboard device 80. The pivot shaft 91 is inserted into the pivot hole, and the pivot shaft 91 makes frictional contact with the wall of the pivot hole. This allows the base 70 to pivot relative to the keyboard device 80 when the user pushes it, and the pivot shaft 91 rotates within the pivot hole. After the base 70 pivots into position, it is held at the corresponding angle by the friction between the pivot shaft 91 and the wall of the pivot hole.

[0071] Similarly, the pivot seat 30 can be pivotally connected to the magnetic seat 20 through various existing structures. The specific connection structures will not be described in detail here.

[0072] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention shall fall within the scope of protection claimed by the present invention.
