[0038] Exemplary embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the invention and to fully convey the scope of the invention to those skilled in the art.

[0039] It should be understood that the terminology used herein is for the purpose of describing particular exemplary embodiments only and is not intended to be limiting. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “described” as used herein may also include the plural forms. The terms “comprising,” “including,” “containing,” and “having” are inclusive and therefore indicate the presence of the stated features, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, elements, components, and / or combinations thereof. The method steps, processes, and operations described herein are not construed as requiring them to be performed in a particular order described or illustrated unless the order of performance is explicitly indicated. It should also be understood that additional or alternative steps may be used.

[0040] Although terms such as first, second, third, etc., may be used in this document to describe multiple elements, components, regions, layers, and / or segments, these elements, components, regions, layers, and / or segments should not be limited by these terms. These terms may be used only to distinguish one element, component, region, layer, or segment from another. Unless the context clearly indicates otherwise, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence. Therefore, the first element, component, region, layer, or segment discussed below may be referred to as the second element, component, region, layer, or segment without departing from the teachings of the exemplary embodiments.

[0041] For ease of description, spatial relative terms may be used in the text to describe the relationship of one element or feature relative to another element or feature, as shown in the figure. These relative terms include, for example, "inside," "outside," "middle," "outer," "below," "below," "above," "over," etc. Such spatial relative terms are intended to include different orientations of the device in use or operation, other than those depicted in the figure. For example, if the device in the figure is flipped, an element described as "below other elements or features" or "below other elements or features" would subsequently be oriented as "above other elements or features" or "above other elements or features." Therefore, the example term "below" can include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions), and the spatial relative descriptors used in the text will be interpreted accordingly.

[0042] Reference Figures 1-11 This invention provides a press-lock and unlock device 100, which can be applied to electronic devices and enables the electronic devices to have a position switching function. Specifically, the electronic device can be a game controller, etc.

[0043] Specifically, the pressing and locking / unlocking device 100 provided by the present invention includes a rotor cover 10, a first rotor 20, a second rotor 30, a first elastic element 40, and a second elastic element 50. The rotor cover 10 is provided with a first locking position 11, a second locking position 12, and a sliding groove 13 connected to the first locking position 11 and the second locking position 12 in the axial direction. The first rotor 20 and the second rotor 30 are both disposed inside the rotor cover 10, and the second rotor 30 is inserted into the sliding groove 13 through a limiting post 33 on its outer periphery. The opposite sides of the first rotor 20 and the second rotor 30 are provided with mating parts. One end of the first elastic element 40 and the second elastic element 50 is connected to the rotor cover 10, and the other end is connected to the first rotor 20 and the second rotor 30, respectively. The first rotor 20 can drive the second rotor 30 to rotate through the mating parts under pressing action. The rotation of the second rotor 30 drives the limiting post 33 to switch between the first locking position 11 and the second locking position 12.

[0044] Specifically, the rotor cover 10 is a shell structure with a central cavity having a circular cross-section. Its sidewalls have a first locking position 11, a second locking position 12 arranged axially, and a sliding groove 13 connecting the first locking position 11 and the second locking position 12. The first locking position 11, the second locking position 12, and the sliding groove 13 are all in communication with the central cavity. The first locking position 11 is closer to the pressing position, and the second locking position 12 is farther from the pressing position.

[0045] Both the first rotor 20 and the second rotor 30 are located in the central cavity of the rotor cover 10. The first rotor 20 can only move axially along the rotor cover 10, while the second rotor 30 is inserted into the sliding groove 13 via a limiting post 33 on its outer periphery. This limiting groove restricts the movement trajectory of the second rotor 30, allowing it to move not only axially but also circumferentially along the rotor cover 10. The first rotor 20 and the second rotor 30 have mating parts on their opposite sides.

[0046] The first elastic element 40 and the second elastic element 50 are both disposed inside the rotor cover 10, and one end of the first elastic element 40 and the second elastic element 50 are connected to the rotor cover 10. The other end of the first elastic element 40 is connected to the first rotor 20, and one end of the second elastic element 50 is connected to the second rotor 30. The elastic forces of the first rotor 20 and the second rotor 30 are in the same direction, with the second rotor 30 pointing towards the first rotor 20.

[0047] Initially, the limiting post 33 is in the first locking position 11. When the first rotor 20 is pressed, it moves axially along the rotor cover 10 towards the second rotor 30. During this movement, the second rotor 30 can be driven to slide along the sliding groove 13 via the mating part until it reaches the bottom of the groove. Then, under the action of the second elastic element 50, it slides along the sliding groove 13 to the second locking position 12, completing the locking. The first rotor 20 then returns to its initial position under the action of the first elastic element 40. During this process, the movement trajectory of the limiting post 33 is as follows: Figure 10 As shown.

[0048] In the locked state, pressing the first rotor 20 again applies force to the second rotor 30, causing the second rotor 30 to slide the limiting post 33 to the bottom of the sliding groove 13. Releasing the press allows the second rotor 30 to slide to the first locking position 11 under the action of the second elastic element 50, while the first rotor 20 returns to its initial position under the action of the first elastic element 40. During this process, the movement trajectory of the limiting post 33 is as follows: Figure 11 As shown.

[0049] This invention, by setting up a rotor cover 10, a first rotor 20, a second rotor 30, and a first elastic body and a second elastic body, allows the locking and unlocking of the product's axial movement to be achieved simply by pressing. Furthermore, the above structure is simple, can be made very small to save space, and is easy to operate, low in cost, and highly reliable, making it widely applicable to products with axial locking and unlocking functions.

[0050] In one specific embodiment, it also includes an upper cover 60 and a base 70, wherein the upper cover 60 is slidably connected to one end of the rotor cover 10 corresponding to the first rotor 20, and the upper cover 60 is provided with a pressing part 62, through which the upper cover 60 can press the first rotor 20; the base 70 is connected to one end of the rotor cover 10 corresponding to the second rotor 30, and is connected to the first elastic member 40 and the second elastic member 50 respectively.

[0051] Specifically, the upper cover 60 is formed as a pressing part 62, which is installed on one end of the rotor cover 10 corresponding to the first rotor 20, and can slide along the axial direction of the rotor cover 10. During the sliding process, the pressing part 62 can apply a pressing force to the first rotor 20. The base 70 is provided at the other end of the rotor cover 10 opposite to the upper cover 60, and is used to seal the opening end of the rotor cover 10.

[0052] In one specific embodiment, locking portions 14 are protruding from the outer periphery of opposite ends of the rotor cover 10, the upper cover 60 is provided with a first locking groove 61 that is adapted to lock the locking portions 14, and the base 70 is provided with a second locking groove 71 that is adapted to slide the locking portions 14.

[0053] Specifically, the locking part 14 is formed as a protrusion, and two locking parts 14 are provided at each end of the rotor cover 10. The base 70 is provided with two second locking grooves 71, and the upper cover 60 is provided with two first locking grooves 61. The first locking grooves 61, the second locking grooves 71, and the locking parts 14 at corresponding positions cooperate to achieve the snap-fit ​​connection between the upper cover 60, the base 70, and the rotor cover 10. Furthermore, along the axial direction of the rotor cover 10, the length of the second locking groove 71 is greater than the length of the locking part 14, and the locking part 14 can slide within the second locking groove 71, thereby achieving the sliding of the upper cover 60 and the rotor cover 10.

[0054] Furthermore, the locking part 14 is also provided with a chamfered guide surface arranged in the axial direction of the rotor shaft, so that the upper cover 60 and the base 70 can be guided by the guide surface to facilitate installation.

[0055] In other embodiments, the locking part 14 at each end of the rotor cover 10 may be 3, 4 or 5, and the 3, 4 or 5 locking parts 14 are evenly distributed along the circumference of the rotor cover 10.

[0056] In one specific embodiment, the rotor cover 10 is formed as a cylindrical tube with one end sealed. The sealed end of the rotor cover 10 is provided with a hollow hole 15, and the pressing part 62 passes through the hollow hole 15 to adapt to pressing the first rotor 20.

[0057] Specifically, the rotor cover 10 is a cylindrical tube with one end sealed and the other end open. The base 70 is connected to the open end of the rotor cover 10 and is used to cooperate with the rotor cover 10 to form a complete central cavity. The upper cover 60 is connected to the sealed end of the rotor cover 10. In order to realize the connection between the upper cover 60 and the first rotor 20, the sealed end of the rotor cover 10 is provided with a hollow hole 15 suitable for the pressing part 62 to pass through.

[0058] Specifically, the number of perforated holes 15 can be one or more. In this embodiment, the number of perforated holes 15 is two.

[0059] In one specific embodiment, both the first elastic element 40 and the second elastic element 50 are springs, and the second elastic element 50 is sleeved on the outside of the first elastic element 40.

[0060] Specifically, the spring not only has elasticity, providing elastic force to the first rotor 20 and the second rotor 30, but also has a relatively stable structure, thereby improving the reliability of the pressing lock and unlocking device 100.

[0061] In this embodiment, one end of the first elastic element 40 and the second elastic element 50 are connected to the base 70, and the other end is connected to the first rotor 20 and the second rotor 30 respectively. At this time, the first elastic element 40 and the second elastic element 50 are compression springs, which can provide the first rotor 20 and the second rotor 30 with an elastic force toward the upper cover 60.

[0062] In other embodiments, the first elastic element 40 and / or the second elastic element 50 are connected to the upper cover 60. Correspondingly, the first elastic element 40 and / or the second elastic element 50 connected to the upper cover 60 are tension springs, which can provide an elastic force toward the upper cover 60 to the first rotor 20 and / or the second rotor 30.

[0063] For ease of installation, the second elastic element 50 is fitted onto the outside of the first elastic element 40.

[0064] In one specific embodiment, the mating part includes a first inclined surface 22 disposed on the first rotor 20 and a second inclined surface 32 disposed on the second rotor 30, wherein the first inclined surface 22 and the second inclined surface 32 are in sliding engagement.

[0065] Specifically, the first rotor 20 and the second rotor 30 are slidably engaged through the first inclined surface 22 and the second inclined surface 32. When a pressing force is applied to the first rotor 20, it moves toward the second rotor 30 along the axial direction of the rotor cover 10. The first inclined surface 22 applies pressing and rotational forces to the second inclined surface 32 of the second rotor 30. The pressing force drives the second rotor 30 to rotate toward the base 70, and the rotational force drives the second rotor 30 to rotate. This allows the second rotor 30 to switch between the first locking position 11 and the second locking position 12 along the sliding groove 13.

[0066] In one specific embodiment, the first rotor 20 is provided with two first wedge blocks 21 in the circumferential direction, each first wedge block 21 is provided with a first inclined surface 22, and the second rotor 30 is provided with two second wedge blocks 31 in the circumferential direction, each second wedge block 31 is provided with a second inclined surface 32.

[0067] Specifically, by setting a first wedge block 21 circumferentially on the first rotor 20 and a second wedge block 31 axially on the second rotor 30, a first inclined surface 22 and a second inclined surface 32 are formed, thereby realizing the drive between the first rotor 20 and the second rotor 30. Moreover, the above structure is simple and easy to implement, which is conducive to improving processing efficiency.

[0068] In one specific embodiment, the sliding groove 13 includes a first inclined groove connected to the first locking position 11 and a second inclined groove connected to the second locking position 12, with the ends of the first inclined groove and the second inclined groove connected together.

[0069] Specifically, the first inclined groove and the second inclined groove are connected in a U-shape.

[0070] In one specific embodiment, a protrusion 16 is formed in the middle of the second inclined groove, the protrusion 16 being adapted to divide the second inclined groove into two segments.

[0071] Specifically, when the limiting post 33 switches from the first locking position 11 to the second locking position, it is limited by the protrusion 16 and directly enters the second inclined groove that communicates with the second locking position 12. Conversely, when switching from the second locking position 12 to the first locking position 11, the limiting post 33 breaks through the position of the protrusion 16 and moves to the end of the second inclined groove away from the second locking position 12, and then moves from there to the first locking position 11.

[0072] In this embodiment, by setting the protrusion 16, the movement trajectory of the limiting post 33 can be limited, thereby improving the control of the limiting post 33 and improving the switching accuracy.

[0073] A second aspect of the present invention also provides an electronic device including a press-lock and unlock device 100 of any of the above-described embodiments. The structure of the press-lock and unlock device 100 is as described in the above embodiments. Since the electronic device of this application has the above-described press-lock and unlock device 100, the electronic device at least has the beneficial effects of the above-described press-lock and unlock device 100, which will not be elaborated further here.

[0074] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
