DETAILED DESCRIPTION

[0047] Various exemplary embodiments of the present application will now be described in detail with reference to the accompanying drawings. It should be noted that unless otherwise specifically stated, the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present application.

[0048] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the present application, its application, or uses.

[0049] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered as part of the specification.

[0050] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0051] It should be noted that like reference numerals and letters refer to similar items in the following figures, and therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0052] like Figures 1 to 17 As shown, the present application provides a multifunctional switch mechanism, including: a key push rod 3, a locking structure and a switch 11, the key push rod 3 has a first position and a second position; when the key push rod 3 is in the first position, the key push rod 3 can move along the first direction to trigger the switch 11; when the key push rod 3 is in the second position, the key push rod 3 can rotate along the second direction to put the locking structure in a locked state or an unlocked state.

[0053] Specifically, Figure 3 As shown, in this embodiment, when the button push rod 3 is in the first position, it can move along the first direction to trigger the switch 11. When the button push rod 3 is in the second position, it can rotate along the second direction to put the locking structure in a locked state or an unlocked state. Among them, the switch 11 can be a touch switch 11 or a button switch 11, and the button push rod 3 can achieve the purpose of triggering the switch 11 by moving along the first direction to touch the touch switch 11 or press the button switch 11. The specific form of the switch 11 can be selected according to the device it controls, and the present application does not limit this. The locked state or unlocked state of the locking structure can be achieved only by its structural features, such as a latch or a hook, or by its material features, such as the locking structure using a magnetic material to match the external structure, and the present application does not limit this.

[0054] In the present application, the first direction is the axial direction of the key push rod 3, and the second direction is the direction of rotation around the axis. The conversion of the key push rod 3 between the first position and the second position and the movement of the key push rod 3 along the first direction or the rotation along the second direction can be achieved by applying external force to pull out, press or rotate the key push rod 3. The present application realizes two different switch functions through a switch mechanism, improves the utilization rate of the switch mechanism, and has a simple and convenient appearance, which is suitable for mass production. It should be noted that in the present application, the state of the locking structure (i.e., the locked state or the unlocked state) can be a self-locking lock or a lock that cooperates with an external structure. For example, when it is used in an electronic device, its switch 11 can be used to control the opening and closing of a functional device in the electronic device, and the locking structure can be used to make two different components of the electronic device realize detachable connection (this embodiment will be reflected in the following embodiments), saving its internal layout space, which is conducive to realizing the lightness and thinness of the electronic device.

[0055] Alternatively, if Figures 4 to 14 As shown, the key push rod 3 is provided with a driving part, and the key push rod 3 can move the locking structure to the locking position through the driving part (refer to Fig.13 ) or unlocked position (ref. Fig.14 ); when the locking structure moves to the locking position, the locking structure is in a locked state, and when the locking structure moves to the unlocking position, the locking structure is in an unlocked state.

[0056] Specifically, in this embodiment, a driving part for driving the locking structure is provided on the key push rod 3, and the key push rod 3 can drive the driving part to move by rotating, so that the driving part can drive the locking structure to move to the locking position or the unlocking position, thereby realizing the locking state or the unlocking state of the locking structure. Among them, the driving part can be a part of the key push rod 3, or it can be a separate part provided on the key push rod 3, that is, the driving part can be an integrated structure with the key push rod 3, or it can be a split structure, which can be selected according to its driving form and position relationship, and this application does not limit this.

[0057] Alternatively, if Figures 2 to 14 As shown, the driving part drives the locking structure to move by means of gear transmission.

[0058] Specifically, gear transmission is a transmission method that uses gears as power transmission, and is the most widely used mechanical transmission method in various modern devices. Its transmission is relatively accurate, efficient, compact, reliable, and has a long service life. In this embodiment, the driving unit drives the locking structure to move by means of gear transmission, which can improve the reliability of its function on the one hand. On the other hand, the gear transmission has a precise transmission ratio, which can accurately control the stroke of the locking structure to ensure that the locking structure can move to a predetermined position to achieve a locked state or an unlocked state.

[0059] Alternatively, if Figures 8 to 14 As shown, the driving part is a gear 31. When the key push rod 3 is in the second position, the gear 31 is assembled on the key push rod 3. The locking structure includes a rack 4. The rack 4 has a tooth portion 41 and a locking portion 42. The tooth portion 41 can mesh with the gear 31. When the key push rod 3 rotates along the second direction, the key push rod 3 drives the rack 4 through the gear 31 to drive the locking portion 42 to move to the locked position or the unlocked position.

[0060] Specifically, in this embodiment, the driving part is a gear 31, and the locking structure includes a rack 4. After the gear 31 is meshed with the toothed portion 41 of the rack 4, the rotational power of the key push rod 3 along the second direction can be converted into a driving force along the linear direction, so that the rack 4 can drive the locking portion 42 to move to the locking position or the unlocking position, so as to respectively realize the locking state and the unlocking state of the locking structure. By designing the parameters of the gear 31 and the rack 4, such as the number of teeth or the transmission ratio, the travel range of the rack 4 can be limited, and the accuracy of the movement of the locking portion 42 can be improved. In addition, the rotation of the key push rod 3 along the second direction can be bidirectional rotation, that is, it can be forward or reverse. In one embodiment, the position of the locking portion 42 can be set as the locking position at the maximum travel of the key push rod 3 in the forward direction, and the position of the locking portion 42 can be set as the unlocking position at the maximum travel of the key push rod 3 in the reverse direction, so as to realize the locking state and the unlocking state of the locking structure.

[0061] When the push rod 3 is in the second position, the gear 31 is assembled on the push rod 3, that is, the gear 31 can rotate with the rotation of the push rod 3. In addition, in this embodiment, when the push rod 3 is in the first position (refer to Figures 4 to 7 ), the gear 31 and the key push rod 3 may be in an assembled relationship or a non-assembled relationship. If they are in a non-assembled relationship, if the key push rod 3 rotates in the second direction, the gear 31 will not rotate with the key push rod 3; if they are in an assembled relationship, the gear 31 and the toothed portion 41 may be in a non-meshing state, if the key push rod 3 rotates in the second direction, the gear 31 will rotate with the key push rod 3, but the rack 4 will not move with the rotation of the gear 31. In this way, it can be avoided that when the key push rod 3 is in the first position, the state of the locking structure is changed due to the key push rod 3 being accidentally touched.

[0062] The above structure can realize the function of triggering the switch 11 when the button push rod 3 moves to the first position, and can also realize the locking or unlocking function of the locking structure when the button push rod 3 moves to the second position, which not only achieves the multi-functional purpose of the switch mechanism, but also simplifies the operation.

[0063] Alternatively, if Figures 13 to 17 As shown, the gear 31 is assembled on the key push rod 3 through a key slot.

[0064] Specifically, the assembly of the key push rod 3 and the gear 31 can be achieved through a keyway. Fig.13 and Fig.14 As shown, a raised convex key 34 may be provided on the key push rod 3, and a matching groove 311 matching the convex key 34 may be provided on the end surface of the gear 31, and the position of the convex key 34 corresponds to the position of the matching groove 311. When the key push rod 3 is in the second position, the convex key 34 is engaged with the matching groove 311 to achieve the assembly of the key push rod 3 and the gear 31. The number and position of the convex key 34 and the matching groove 311 can be selected according to actual conditions, such as Fig.16 and Fig.17 As shown, two convex keys 34 are arranged on the key push rod 3, and two matching grooves 311 are arranged on the end surface of the gear 31 corresponding to the two convex keys 34. When the key push rod 3 moves to the second position, the gear 31 is assembled on the key push rod 3 through the matching grooves 311 and the convex keys 34. When the key push rod 3 rotates, the gear 31 can rotate with the key push rod 3. In another embodiment, the convex keys 34 can also be arranged on the gear 31, and the matching grooves 311 can be arranged on the key push rod 3, and the present application does not limit this. The matching grooves 311 and the convex keys 34 can be matched or disengaged according to the position of the key push rod 3, so that the gear 31 can be assembled with the key push rod 3 when needed, and the structure is simple and reliable.

[0065] Alternatively, if Figures 1 to 14 As shown, the locking structure also includes a limiting groove 12, the rack 4 is located in the limiting groove 12, and the tooth portion 41 and the locking portion 42 are respectively exposed in the limiting groove 12, and the button push rod 3 drives the rack 4 to move in the limiting groove 12 through the gear 31.

[0066] Specifically, Fig.13 and Fig.14 As shown, in this embodiment, in addition to limiting the travel range of the rack 4 by the parameters of the gear 31 and the rack 4, the travel range of the rack 4 can also be limited by the limit groove 12, so that the locking portion can be accurately located at the locking position or the unlocking position to ensure the locking state of the locking structure. In addition, the limit groove 12 can also provide external protection for the rack 4 to prevent the rack 4 from being damaged by external forces and increase the service life of the locking structure. In one embodiment, as Fig.13and Fig.14 As shown, the limit groove 12 can be formed by a slide groove and a cover plate. During the assembly process, the rack 4 can be first set in the slide groove, and then sealed with a cover plate to improve the protection function of the limit groove 12. The tooth portion 41 and the locking portion 42 are respectively exposed in the limit groove 12 (can be extended from the limit groove 12, or can be not extended from the limit groove 12 but only exposed from the limit groove 12), which facilitates the meshing of the tooth portion 41 with the gear 31 and the movement of the locking portion 42, thereby improving the reliability of the structure.

[0067] Alternatively, if Figures 1 to 11 As shown, the multifunctional switch mechanism further includes a limiting structure, which can enable the key push rod 3 to be located at the first position or the second position.

[0068] Specifically, in this embodiment, the limiting structure can make the key push rod 3 be located at the first position or the second position, so as to realize the function of the key push rod 3 triggering the switch 11 or driving the locking function of the locking structure. For example, in an electronic device having a first component and a second component, the key push rod 3 can be movably arranged on the first component, and the limiting structure is also arranged on the first component. When the limiting structure makes the key push rod 3 located at the first position, the key push rod 3 can move along the first direction to trigger the switch 11. When the limiting structure makes the key push rod 3 located at the second position, the key push rod 3 can rotate along the second direction, so that the first part can be detachably connected with the second part through the locked state or unlocked state of the locking structure. Among them, the locking structure can be a hook, which is locked by being mutually engaged with the second part, and the locking structure can also be a latch, which is locked by being moved and plugged into the second part. This application does not limit this.

[0069] Optionally, the limiting structure includes a pair of elastic arms 13, each elastic arm 13 has a first protrusion 131 and a second protrusion 132, refer to Fig.15 The key push rod 3 has a concave area 32, referring to Fig.16 In the case where the first protrusion 131 is located in the concave area 32, the key push rod 3 is located at the first position, such as Figure 4 or Figure 7 In the case where the second protrusion 132 is located in the concave area 32, the key push rod 3 is located at the second position, such as Figure 8 or Fig.11 shown.

[0070] Specifically, in this embodiment, the elastic arm 13 is relatively arranged on both sides of the key push rod 3, and the first protrusion 131 and the second protrusion 132 can limit each other with the concave area 32 of the key push rod 3, so that the key push rod 3 is kept at the first position or the second position. In addition, the elasticity of the elastic arm 13 can provide a reset function for the key push rod 3 to move along the first direction at the first position. In addition, support platforms 15 can also be respectively arranged at the switch 11, the elastic arm 13, and the key push rod 3 to ensure the connection and matching relationship of each component, such as Figures 1 to 14 shown.

[0071] According to the second aspect of the present application, an electronic device is also provided, comprising a first shell 1, a second shell 2 and the multifunctional switch mechanism of the first aspect, wherein a key push rod 3 is movably arranged on the first shell 1, and a trigger end is opposite to a switch 11; when the key push rod 3 moves along a first direction, the trigger end triggers the switch 11; when the key push rod 3 rotates along a second direction, the first shell 1 and the second shell 2 are locked or disengaged with each other through a locking structure.

[0072] Specifically, refer to Figures 1 to 17 The electronic device provided in this embodiment adopts a multifunctional switch mechanism, and the key push rod 3 is movably arranged on the first housing 1. The switch 11 is arranged relative to the trigger end of the key push rod (i.e., the end opposite to the operating end 33). On the one hand, it can provide a switch function for the electronic devices in the electronic device. On the other hand, the key push rod 3 can also drive the locking structure to cooperate with the second housing 2 to lock or disengage the first housing 1 and the second housing 2, that is, the first housing 1 and the second housing 2 are detachably connected to facilitate maintenance of the electronic device. By setting a multifunctional switch mechanism, this application realizes two functional requirements of the electronic device, saves the layout space inside the electronic device, and realizes the requirements for thinness of the electronic device.

[0073] In one embodiment, the function of triggering the switch 11 and the function of detachably connecting the first shell 1 and the second shell 2 can be realized by the following operations. The key push rod 3 is movably arranged on the first shell 1, and one end thereof is exposed from the first shell 1 as the operating end 33. When the key push rod 3 is located at the first position, the key push rod 3 is pressed along the first direction, and the triggering end touches or presses the switch 11, thereby triggering the switch 11. When the key push rod 3 is located at the second position, the operating end 33 is rotated to realize the forward or reverse rotation of the key push rod 3 (the forward and reverse rotation here are only for distinguishing the rotation direction and are not specifically defined). The rotation of the key push rod 3 drives the locking structure to cooperate with the second shell 2, so that the first shell 1 and the second shell 2 can be locked or disengaged from each other.

[0074] The key push rod 3 can be moved from the first position to the second position by pulling the key push rod 3 out in a direction away from the first housing 1 to a predetermined position, and correspondingly, the key push rod 3 can be moved from the second position to the first position by pressing the key push rod 3 into the first housing 1. In this embodiment, the electronic device can be an AR (augmented reality), VR (virtual reality) or other device, which is not limited in this application.

[0075] Optionally, a matching portion 21 is provided on the second housing 2 , and the matching portion 21 matches the locking structure.

[0076] Specifically, in this embodiment, a matching portion 21 is provided on the second housing 2 for matching with the locking structure. For example, in one embodiment, the matching portion 21 matches with the locking portion 42 of the locking structure. The locking portion 42 and the matching portion 21 can both be configured as hook structures, such as Fig.13 and Fig.14 When the locking portion 42 moves to the locking position, the locking portion 42 and the matching portion 21 are hooked together to achieve the locking of the first shell 1 and the second shell 2. Fig.13 When the locking portion 42 moves to the open position, the locking portion 42 is disengaged from the matching portion 21, so that the first shell 1 and the second shell 2 are separated. Fig.14 The second housing 2 is provided with a matching portion 21 to facilitate the matching between the locking structure and the second housing 2 . The form of the matching portion 21 can be designed to match the form of the locking structure without affecting the function of the second housing 2 .

[0077] The above embodiments focus on the differences between the various embodiments. As long as the different optimization features between the various embodiments are not contradictory, they can be combined to form a better embodiment. Considering the simplicity of the text, they will not be repeated here.
