Description

Technical Field

[0001] This disclosure relates to the field of electrical equipment, and particularly to a locking / unlocking mechanism, a switch, a socket, and electrical equipment. Background Technology

[0002] Many electrical devices can be switched by pressing a button, such as common switches and switch sockets. Taking a common wall switch as an example, pressing the rocker switch toggles the on / off state of the switch.

[0003] This type of device poses a significant risk of accidental operation. Take a switch as an example: a simple press can change its state. When the switch needs to be in a conducting or discontinuous state, if someone accidentally presses the switch, it may change its state, causing the switch to be incorrectly turned on or off. This not only affects its use but also poses a certain safety hazard. Summary of the Invention

[0004] This disclosure provides a locking / unlocking mechanism, switch, socket, and electrical equipment that can prevent accidental operation and eliminate safety hazards. The technical solution is as follows:

[0005] In a first aspect, the present disclosure provides a locking and unlocking mechanism, which includes a base, a motion module and a first locking module. The motion module is pivotally connected to the base, and the first locking module is located on one side of the rotation axis of the motion module and connected to the motion module. The first locking module has a locked state and an unlocked state.

[0006] The first locking module includes a locking element and a button. When the first locking module is in a locked state, the locking element locks the motion module, and the button is used to release the locked state of the first locking module when pressed.

[0007] Optionally, the motion module includes a rocker with a button hole, the locking member is located on the side of the rocker near the base and connected to the rocker, and the button is located in the button hole;

[0008] When the first locking module is in the locked state, the button protrudes from the surface of the rocker away from the base.

[0009] Optionally, the first locking module is located in the first part of the rocker, the first part is located on one side of the rotation axis, and can be tilted or pressed relative to the base;

[0010] When the first part is tilted relative to the base, the first locking module is in a locked state.

[0011] Optionally, the locking element includes a movable pin that contacts the button and is used to move relative to the rocker under the action of the button. The moving direction of the movable pin intersects with the moving direction of the button. The movable pin is used to cooperate with the base to lock the motion module.

[0012] Optionally, the base has a stop protrusion on the side opposite to the rocker, the stop protrusion having a top surface and a side surface. When the first locking module is in the locked state, the movable pin is located at the top surface, and the side wall of the movable pin is opposite to the top surface. When the first locking module is in the unlocked state, the movable pin is located on one side of the stop protrusion, and the end face of the movable pin is opposite to the side surface.

[0013] Optionally, the locking element further includes a mounting base and a resilient reset element. The mounting base is connected to the rocker, and both the movable pin and the resilient reset element are located in the mounting base. The resilient reset element is located at one end of the movable pin, and the other end of the movable pin extends out relative to the mounting base.

[0014] The mounting base has an opening on the side near the rocker, the opening being located to the side of the movable pin and opposite to the button hole, the button being located in the opening.

[0015] Optionally, the movable pin includes a connected rod-shaped portion and a wedge-shaped portion, the wedge-shaped portion being located on the side of the rod-shaped portion closer to the button, the wedge-shaped portion having an inclined surface, and the button contacting the inclined surface.

[0016] Optionally, the locking and unlocking mechanism further includes a second locking module. The first locking module and the second locking module are located on both sides of the rotation axis of the motion module. The structure of the second locking module is the same as that of the first locking module. When the first locking module is in the locked state, the second locking module is in the unlocked state, and when the first locking module is in the unlocked state, the second locking module is in the locked state.

[0017] Secondly, embodiments of this disclosure also provide a switch, the switch including a stationary contact, a moving contact and a locking / unlocking mechanism as described in the first aspect, the stationary contact being located in the base, and the moving contact being connected to the motion module for contacting or separating from the stationary contact under the drive of the motion module.

[0018] Thirdly, embodiments of this disclosure also provide a socket, the socket including a socket assembly and a switch as described in the second aspect, the surface of the motion module away from the base having a socket hole, the socket assembly being located in the motion module and opposite to the socket hole, and the socket assembly being electrically connected to the moving contact.

[0019] Fourthly, embodiments of this disclosure also provide an electrical device, which includes a locking / unlocking mechanism as described in the first aspect, a switch as described in the second aspect, or a socket as described in the third aspect.

[0020] The beneficial effects of the technical solutions provided in this disclosure include at least the following:

[0021] By incorporating a first locking module, when the first locking module is in the locked state, its locking mechanism locks the moving module, preventing it from rotating relative to the base. Pressing the button on the first locking module releases the lock, allowing the moving module to rotate relative to the base. Because the first locking module requires the module to be released before it can rotate, this design prevents accidental operation and helps eliminate safety hazards. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this disclosure clearer, the embodiments of this disclosure will be described in further detail below with reference to the accompanying drawings.

[0036] Unless otherwise defined, the technical or scientific terms used herein shall have the ordinary meaning understood by one of ordinary skill in the art to which this disclosure pertains. The terms “first,” “second,” “third,” and similar terms used in this patent application specification and claims do not indicate any order, quantity, or importance, but are merely used to distinguish different components.

The terms “comprising” or “including” and similar terms mean that the element or object preceding “comprising” or “including” encompasses the element or object listed following “comprising” or “including” and its equivalents, and do not exclude other elements or objects. The terms “connected” or “linked” and similar terms are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. The terms “upper,” “lower,” “left,” “right,” etc., are used only to indicate relative positional relationships, and these relative positional relationships may change accordingly when the absolute position of the described object changes.

[0037] Figure 1 This is a schematic diagram of a locking / unlocking mechanism provided in an embodiment of this disclosure. Figure 1 As shown, the locking and unlocking mechanism includes a base 20, a motion module 10, and a first locking module 30. The motion module 10 is pivotally connected to the base 20. The first locking module 30 is located on one side of the rotation axis m of the motion module 10 and is connected to the motion module 10. The first locking module 30 has a locked state and an unlocked state.

[0038] Figure 2 This is a schematic diagram of the structure of a first locking module provided in an embodiment of this disclosure. Figure 2As shown, the first locking module 30 includes a locking element 31 and a button 32. When the first locking module 30 is in the locked state, the locking element 31 locks the motion module 10, and the button 32 is used to release the locked state of the first locking module 30 when pressed.

[0039] By setting a first locking module 30, when the first locking module 30 is in the locked state, the locking element 31 of the first locking module 30 locks the motion module 10, preventing the motion module 10 from rotating relative to the base 20. When the button 32 of the first locking module 30 is pressed, the first locking module 30 is unlocked, allowing the motion module 10 to rotate relative to the base 20. Under the action of the first locking module 30, to allow the motion module 10 to rotate relative to the base 20, the locking state of the first locking module 30 must first be released by pressing the button 32, which can prevent accidental operation of the motion module 10 and help eliminate safety hazards.

[0040] This locking and unlocking mechanism can be applied to devices such as switches and sockets. For example, Figure 3 This is a schematic diagram of a switch provided in an embodiment of this disclosure. The switch may include a stationary contact, a moving contact, and a locking / unlocking mechanism. The stationary contact is located in the base 20, and the moving contact is connected to the motion module 10. The moving contact is used to contact or separate from the stationary contact under the action of the motion module 10.

[0041] The motion module 10 is the movable part of the switch. By pressing the motion module 10 to a position away from the rotation axis m, for example... Figure 3 The position indicated by the middle arrow allows the portion of the motion module 10 away from the rotation axis m to be tilted or pressed relative to the base 20. For example, when the motion module 10 is pressed at the position indicated by the arrow, the moving contact rotates with the motion module 10 and contacts the stationary contact, thus turning on the switch; when the motion module 10 is tilted at the position indicated by the arrow, the moving contact separates from the stationary contact, thus turning off the switch.

[0042] By locking the motion module 10 through the first locking module 30, the motion module 10 cannot move relative to the base 20, thus keeping the moving contact and the stationary contact in contact or separate, thereby keeping the switch on or off, and preventing the switch state from being switched incorrectly due to misoperation.

[0043] The embodiments disclosed herein are as follows Figure 4 Taking the socket shown as an example, the structure and function of the locking and unlocking mechanism will be explained in detail. Figure 4 This is a schematic diagram of the structure of a socket provided in an embodiment of this disclosure. The socket can be a switch socket, that is, the socket combines the structure and function of a switch. Figure 4 The image also shows a plug 50 that connects to a socket. (For example...) Figure 4As shown, in this socket, the surface of the motion module 10 away from the base 20 has a socket 10a for connecting the plug 40.

[0044] Sockets can be embedded in objects, such as in walls. Figure 4 Only the structure where the socket is exposed outside the wall is shown. (For example...) Figure 4 As shown, the socket 10a is used to connect to the plug 50. The motion module 10 acts as a "button" and can rotate relative to the base 20. By rotating the motion module 10, it can be powered on or off. Before the plug 50 is connected to the motion module 10, the motion module 10 is in a powered-off state. After the plug 50 is connected to the motion module 10, pressing the motion module 10 causes it to rotate by a certain angle, switching it to a powered-on state. That is, even if the plug 50 is connected to the motion module 10, it will not be connected to the circuit if the motion module 10 is not operated. Due to the presence of the first locking module 30, the motion module 10 can be prevented from being accidentally operated, thus preventing the plug 50 from being mistakenly connected to or disconnected from the circuit.

[0045] Figure 5 This is an exploded structural diagram of a socket provided in an embodiment of this disclosure. For example... Figure 5 As shown, the socket also includes a socket assembly 12, which is located in the motion module 10 and opposite to the socket 10a. The socket assembly 12 is electrically connected to the moving contact. When the plug is connected to the socket 10a, the plug pins make electrical contact with the socket assembly 12.

[0046] The motion module 10 includes a module housing 11. A socket assembly 12 is located inside the module housing 11. A moving contact may be located on the side of the motion module 10 near the base 20 and is electrically connected to the socket assembly 12.

[0047] The base 20 includes a mounting slot 201 and a mounting bracket 202. The mounting slot 201 is connected to the mounting bracket 202. The motion module 10 is mounted in the mounting slot 201 and pivotally connected to it. The socket also includes a conductive element 21, which is located in the mounting slot 201. The conductive element 21 is connected to the stationary contact.

[0048] Pressing the motion module 10 causes it to rotate relative to the base 20, thereby changing the relationship between the moving contact and the stationary contact. When the moving contact and the stationary contact are separated, the socket assembly 12 is not energized, and the motion module 10 is in a de-energized state. Pressing the motion module 10 causes the moving contact to contact the stationary contact, energizing the socket assembly 12 and putting the motion module 10 into an energized state.

[0049] like Figure 5As shown, in this socket, the module housing 11 can be a detachable structure to facilitate the assembly of the motion module 10. The module housing 11 includes a rocker plate 111 and a bottom shell 112. The rocker plate 111 and the bottom shell 112 are connected by a snap-fit. The socket 10a is located on the rocker plate 111. The socket assembly 12 can be located between the rocker plate 111 and the bottom shell 112.

[0050] Figure 6 This is an assembly diagram of a motion module and a base provided in an embodiment of this disclosure. Figure 6 Only the mounting slot 201 of the base 20 is shown. (See image.) Figure 6 As shown, rocker 111 has a button hole 111a. Figure 7 This is a schematic diagram of the assembly of a rocker and a first locking module provided in an embodiment of this disclosure. Figure 7 The side of the rocker 111 near the base 20 is shown. (As shown) Figure 7 As shown, the locking member 31 is located on the side of the rocker 111 near the base 20 and is connected to the rocker 111.

[0051] Figure 8 This is a schematic diagram of the structure of a switch provided in an embodiment of this disclosure. Figure 8 The switch shown indicates that the first locking module 30 is in a locked state. Figure 8 As shown, button 32 is located in button hole 111a. When the first locking module 30 is in the locked state, button 32 protrudes from the surface of rocker 111 away from base 20.

[0052] The motion module 10 can be operated by pressing the rocker arm 111. When the first locking module 30 is locked, if it is necessary to operate the motion module 10, the button 32 must be pressed first to unlock it.

[0053] When the first locking module 30 is in the locked state, the button 32 protrudes from the surface of the rocker plate 111 away from the base 20, making it convenient to press the button 32.

[0054] like Figure 8 As shown, the rotation axis m of the motion module 10 is located in the middle of the rocker 111. The rocker 111 includes a first part located on one side of the rotation axis m and a second part located on the other side of the rotation axis m. Both the first part and the second part can be tilted or pressed relative to the base 20. When the first part of the rocker 111 is pressed, the second part of the rocker 111 tilts; when the second part of the rocker 111 is pressed, the first part of the rocker 111 tilts.

[0055] The first locking module 30 is located in the first part of the rocker 111. When the first part is tilted relative to the base 20, the first locking module 30 is in a locked state.

[0056] Since button 32, like rocker 111, is operated by pressing, and when the first part of rocker 111 is tilted relative to base 20, the first locking module 30 is locked, at which point button 32 protrudes from the surface of rocker 111 away from base 20. After button 32 is pressed, the first locking module 30 is unlocked. Continuing to press down on the first part of rocker 111 will cause the second part of rocker 111 to tilt, changing the state of the socket, making operation convenient.

[0057] Figure 9 yes Figure 8 AA section diagram. (See diagram below.) Figure 9 As shown, the locking component 31 includes a movable pin 311, which contacts the button 32 and is used to move relative to the rocker arm 111 under the action of the button 32. The moving direction of the movable pin 311 intersects the moving direction of the button 32. The movable pin 311 is used to cooperate with the base 20 to lock the motion module 10.

[0058] By utilizing the cooperation between button 32 and movable pin 311, the movement of button 32 in the pressing direction is converted into the movement of movable pin 311, and movable pin 311 and base 20 are used to form a locking mechanism for motion module 10.

[0059] For example, the direction of movement of the active pin 311 is perpendicular to the direction of movement of the button 32.

[0060] like Figure 9 As shown, the locking member 31 also includes a mounting base 312 and a resilient reset member 313. The mounting base 312 is connected to the rocker arm 111, and both the movable pin 311 and the resilient reset member 313 are located in the mounting base 312. The resilient reset member 313 is located at one end of the movable pin 311, and the other end of the movable pin 311 extends out relative to the mounting base 312.

[0061] The mounting base 312 has an opening 312a on the side near the rocker arm 111. The opening 312a is located on the side of the movable pin 311 and opposite to the button hole 111a. The button 32 is located in the opening 312a.

[0062] The elastic reset member 313 can push the movable pin 311 to move and reset the movable pin 311 during the process of the first locking module 30 switching from the unlocked state to the locked state. The movable pin 311, the elastic reset member 313 and the button 32 are installed on the mounting base 312 to form a whole, which facilitates the whole assembly onto the rocker plate 111.

[0063] Reference Figure 2As shown, the mounting base 312 is rectangular in shape and has a first surface 3121, a second surface 3122, and a third surface 3123, which are adjacent to each other. The first surface 3121 has a pin hole 312b in which a movable pin 311 is inserted. An opening 312a is located on the second surface 3122. The movable pin 311 can extend or retract relative to the first surface 3121 under the action of the button 32 and the elastic reset member 313. A fixing plate 3124 is connected to the third surface 3123. The fixing plate 3124 is used to connect to the rocker arm 111, for example, by means of screws.

[0064] like Figure 9 As shown, the movable pin 311 includes a rod-shaped portion 3111 and a wedge-shaped portion 3112 connected together. The wedge-shaped portion 3112 is located on the side of the rod-shaped portion 3111 near the button 32, and the wedge-shaped portion 3112 has an inclined surface 3113, which contacts the button 32.

[0065] The inclined surface 3113 of the wedge-shaped portion 3112 cooperates with the button 32. When the button 32 is pressed, the force exerted by the button 32 on the wedge-shaped portion 3112 is applied to the inclined surface 3113. This force has a component force perpendicular to the pressing direction of the button 32. Under the action of this component force, the movable pin 311 moves into the mounting base 312.

[0066] When the movable pin 311 is reset, it moves outward from the mounting base 312 under the action of the elastic reset member 313. At this time, the inclined surface 3113 of the wedge-shaped part 3112 pushes the button 32 in turn. The force exerted by the inclined surface 3113 on the button 32 generates a component force perpendicular to the moving direction of the movable pin 311. Under the action of this component force, the button 32 pops up.

[0067] Figure 10 This is a schematic diagram of the structure of a base provided in an embodiment of this disclosure. Figure 10 The mounting bracket 202 of the base 20 is shown, but the mounting slot 201 is omitted. (See attached image.) Figure 10 As shown, the side of the base 20 opposite to the rocker arm 111 has a stop protrusion 203. The stop protrusion 203 has a top surface 203a and a side surface 203b. The top surface 203a is the surface of the stop protrusion 203 near the rocker arm 111.

[0068] When the first locking module 30 is in a locked state, refer to Figure 9 The movable pin 311 is located at the top surface 203a of the stop protrusion 203, and the side wall of the movable pin 311 is opposite to the top surface 203a of the stop protrusion 203. Figure 11 This is a partially enlarged schematic diagram of a base provided in an embodiment of this disclosure. Figure 11 As shown Figure 9At the same location in the magnified area, such as Figure 11 As shown, when the first locking module 30 is unlocked, the movable pin 311 is located on one side of the stop protrusion 203, and the end face of the movable pin 311 is opposite to the side 203b of the stop protrusion 203.

[0069] When the first locking module 30 is in the locked state, if the rocker arm 111 is pressed directly without pressing the button 32 of the first locking module 30, the top surface 203a of the stop protrusion 203 will abut against the movable pin 311, preventing the rocker arm 111 from being pressed down, because the side wall of the movable pin 311 is opposite to the top surface 203a of the stop protrusion 203. By pressing the button 32, the movable pin 311 moves into the mounting base 312. When the movable pin 311 moves beyond the top surface 203a of the stop protrusion 203, it loses the support of the stop protrusion 203, allowing the first part of the rocker arm 111 to be pressed down smoothly, and the first locking module 30 is unlocked. After the first part of the rocker arm 111 is pressed down, the movable pin 311 is located on one side of the stop protrusion 203, and the end face of the movable pin 311 contacts the side surface 203b of the stop protrusion 203. Under the stopping action of the side 203b of the stop protrusion 203, the movable pin 311 cannot extend, keeping the first locking module 30 in the unlocked state. At this time, if the second part of the rocker 111 is pressed, causing the first part of the rocker 111 to lift, the movable pin 311 moves away from the base 20. When the end face of the movable pin 311 moves beyond the side 203b of the stop protrusion 203, the movable pin 311 loses the stopping action of the side 203b of the stop protrusion 203, and thus extends out of the mounting base 312 under the action of the elastic reset member 313, and the first locking module 30 switches back to the locked state.

[0070] like Figure 8 As shown, the locking and unlocking mechanism may further include a second locking module 40. The first locking module 30 and the second locking module 40 are located on opposite sides of the rotation axis m of the motion module 10. The structure of the second locking module 40 is the same as that of the first locking module 30. When the first locking module 30 is in the locked state, the second locking module 40 is in the unlocked state, and when the first locking module 30 is in the unlocked state, the second locking module 40 is in the locked state.

[0071] Like the first locking module 30, the second locking module 40 also has a locked state and an unlocked state, capable of locking the motion module 10. The motion module 10 has two states: with reference to the rotation axis m, it is in a state where the side of the motion module 10 closest to the first locking module 30 is tilted upwards, and in a state where the side of the motion module 10 closest to the second locking module 40 is tilted upwards. By setting two locking modules, and with the states of the first locking module 30 and the second locking module 40 being opposite, the motion module 10 can be locked in both states.

[0072] by Figure 8 Taking the socket shown as an example, the first locking module 30 is located in the first part of the rocker arm 111, and the second locking module 40 is located in the second part of the rocker arm 111. When the first part of the rocker arm 111 is pressed, the second part of the rocker arm 111 is raised. Although the first locking module 30 is in the unlocked state, the second locking module 40 is in the locked state, locking the motion module 10. Without the second locking module 40 being unlocked, the second part of the rocker arm 111 cannot be pressed, and therefore the on / off state of the socket cannot be changed. Conversely, when the second part of the rocker arm 111 is pressed, the first part of the rocker arm 111 is raised. Although the second locking module 40 is in the unlocked state, the first locking module 30 is in the locked state, locking the motion module 10. Without the first locking module 30 being unlocked, the first part of the rocker arm 111 cannot be pressed, and therefore the on / off state of the socket cannot be changed. It is evident that by setting two locking modules, the safety of the socket is further improved, preventing accidental operation and eliminating safety hazards.

[0073] The second locking module 40 also includes a button 32, a movable pin 311, and other structures, which are the same as those of the first locking module 30. For details, please refer to the previous description of the structure of the first locking module 30.

[0074] Figure 12 This is a schematic diagram of a rocker provided in an embodiment of this disclosure. Figure 12 As shown, the surface of the rocker arm 111 near the base 20 may have a connection structure for connecting the first locking module 30 and the second locking module 40. This connection structure may include at least one of a snap-fit ​​1111 and a connecting post 1112.

[0075] The snap-fit ​​1111 is used to engage with the mounting base 312, and the connecting post 1112 is used to connect with the fixing plate 3124 on the outer side wall of the mounting base 312, for example, by screws.

[0076] This disclosure also provides an electrical device that may include the locking / unlocking mechanism, switch, or socket provided in this disclosure.

[0077] The above description is merely an optional embodiment of this disclosure and is not intended to limit this disclosure. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this disclosure should be included within the protection scope of this disclosure.
