Description

Technical Field

[0001] This application relates to the field of switch technology, and in particular to a self-locking switch and a docking station. Background Technology

[0002] In various electronic devices, mechanical equipment, and electrical control systems, switches are key components for controlling the on / off state of circuits or the operating status of equipment, and their performance and reliability are of paramount importance. However, switches in related technologies are prone to unexpected state switching when subjected to external interference, vibration, or accidental contact, resulting in low reliability. Utility Model Content

[0003] In view of this, the main objective of the embodiments of this application is to provide a self-locking switch and a docking station with high reliability.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows:

[0005] One embodiment of this application provides a self-locking switch, including:

[0006] A housing having a receiving cavity;

[0007] Locking element;

[0008] A rocker arm, at least a portion of which is located within the receiving cavity;

[0009] The self-locking switch has a locked state and an unlocked state. When the self-locking switch is in the locked state, the locking member is connected to the rocker arm to restrict the movement of the rocker arm. When the self-locking switch is in the unlocked state, the locking member is separated from the rocker arm to prevent the movement of the rocker arm.

[0010] The locking element is movably disposed within the receiving cavity so that the self-locking switch switches between the locked state and the unlocked state.

[0011] In one embodiment, the self-locking switch further includes a slider located on one side of the locking member along a first direction, the first direction being perpendicular to the extending direction of the locking member. When the self-locking switch is in the locked state, the slider abuts against the locking member to restrict the locking member from moving toward the side opposite to the rocker arm. Along the first direction, the slider switches between abutting and disengaging with the locking member by sliding.

[0012] In one embodiment, a portion of the locking member protrudes towards the side near the sliding member to form a first protrusion. When the self-locking switch is in the locked state, the first protrusion abuts against the side of the sliding member near the rocker arm.

[0013] In one embodiment, another portion of the locking member protrudes towards the side closer to the sliding member to form a second protrusion. As the locking member moves towards the rocker arm, the second protrusion abuts against the side of the sliding member away from the rocker arm to push the sliding member away from the locking member, thereby separating the locking member and the sliding member.

[0014] In one embodiment, the slider has a first abutting surface on the side near the second protrusion. From the side away from the locking member to the side near the locking member, the first abutting surface is inclined toward the side near the rocker arm. The locking member has a second abutting surface, which is parallel to the first abutting surface. During the movement of the locking member toward the rocker arm, the first abutting surface abuts against the second abutting surface.

[0015] In one embodiment, a portion of the rocker arm is recessed to form a locking channel, and the locking member at one end near the rocker arm can be movably inserted into the locking channel.

[0016] In one embodiment, the housing includes a first sidewall;

[0017] A portion of the first sidewall is open to form a first channel, the first channel extending along the extension direction of the locking member, and the rocker arm is movably disposed within the first channel along the extension direction of the first channel; and / or,

[0018] Another portion of the first sidewall is open to form a second channel extending in a first direction. Along the extension direction of the second channel, the rocker arm is movably disposed within the second channel, and the first direction is perpendicular to the extension direction of the locking member.

[0019] In one embodiment, the housing has a first opening, the locking member is movably inserted into the first opening, a portion of the locking member protrudes along a first direction to form an abutment portion, the abutment portion is located on the side of the locking member near the first opening, the cross-sectional dimension of the abutment portion is larger than the cross-sectional dimension of the first opening, and the first direction is perpendicular to the extension direction of the locking member.

[0020] In one embodiment, the self-locking switch further includes an elastic element, and the housing also has a receiving groove located within the receiving cavity and on the side of the abutment portion opposite to the first opening. At least a portion of the elastic element is located within the receiving groove, with one end of the elastic element abutting against the groove wall on the side of the receiving groove opposite to the first opening, and the other end abutting against the abutment portion.

[0021] Another embodiment of this application provides a docking station, which includes a processor and a self-locking switch as described in any one of the above embodiments, wherein the self-locking switch is signal-connected to the processor.

[0022] This application provides a self-locking switch and a docking station. The self-locking switch includes a housing, a locking member, and a rocker arm. The housing has a receiving cavity, and at least a portion of the rocker arm is located within the receiving cavity. The self-locking switch has a locked state and an unlocked state. When the self-locking switch is in the locked state, the locking member is connected to the rocker arm to restrict the rocker arm's movement. When the self-locking switch is in the unlocked state, the locking member is separated from the rocker arm to prevent the rocker arm's movement. The locking member is movably disposed within the receiving cavity to allow the self-locking switch to switch between the locked and unlocked states. Therefore, on the one hand, in the locked state, the locking member effectively restricts the rocker arm, significantly reducing malfunctions of the self-locking switch caused by accidental contact, vibration, or other factors, thereby improving the reliability of the self-locking switch. On the other hand, in the unlocked state, the locking member is separated from the rocker arm, allowing the rocker arm to move freely to switch between different modes, thus improving the practicality of the self-locking switch and meeting the diverse needs of users in different scenarios.

The following embodiments are only used to more clearly illustrate the technical solutions of this application, and are therefore only examples, and should not be used to limit the scope of protection of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application according to the specific circumstances.

[0035] One embodiment of this application provides a self-locking switch; please refer to [link / reference]. Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 The self-locking switch includes a housing 10, a locking element 20, and a rocker arm 30.

[0036] The housing 10 has a receiving cavity.

[0037] At least a portion of the joystick 30 is located within the receiving cavity.

[0038] The self-locking switch has a locked state and an unlocked state. When the self-locking switch is in the locked state, the locking member 20 is connected to the rocker arm 30 to restrict the movement of the rocker arm 30. When the self-locking switch is in the unlocked state, the locking member 20 is separated from the rocker arm 30 to prevent the movement of the rocker arm 30.

[0039] The locking element 20 is movably disposed within the receiving cavity to allow the self-locking switch to switch between a locked state and an unlocked state.

[0040] Another embodiment of this application provides a docking station, which includes a processor and a self-locking switch according to any one of the embodiments of this application, wherein the self-locking switch is signal-connected to the processor.

[0041] Specifically, housing 10 refers to the external structure of the self-locking switch, which serves to protect the internal structure and support other components.

[0042] The housing 10 provides installation space and movement area for components such as the locking element 20 and the rocker arm 30, while also preventing external factors such as dust and moisture from entering, ensuring the normal operation of the internal components of the switch.

[0043] Locking component 20 refers to a component that can lock the joystick 30 and restrict its movement.

[0044] The connection or separation of the locking element 20 and the rocker arm 30 controls the self-locking switch to switch between the locked and unlocked states.

[0045] The joystick 30 refers to the component used to control the on or off state of the self-locking switch, thereby controlling the circuit and enabling the docking station to switch between different modes.

[0046] For example, the docking station includes a display module and a control system, with the control system signal-connected to both the processor and the display module. When the self-locking switch is unlocked and the joystick 30 rebounds immediately after being pressed down, the processor receives the signal and transmits it to the control system. The control system then drives the display module to brighten, and the display module continuously displays for a first set duration before dimming. The first set duration is greater than or equal to 8 seconds and less than or equal to 12 seconds. For example, the first set duration is 8 seconds, 10 seconds, or 12 seconds.

[0047] For example, when the self-locking switch is in the unlocked state and the joystick 30 is pressed down for a second set duration, the second set duration being greater than or equal to 1 second and less than or equal to 3 seconds, the docking station enters a professional charging mode where the display module and hub module are off. For example, the second set duration is 1 second, 2 seconds, or 3 seconds.

[0048] For example, when the self-locking switch is in the unlocked state and the joystick 30 is pressed down for a third set duration, the third set duration being greater than or equal to 6 seconds and less than or equal to 10 seconds, the docking station enters a low-power mode where the output module is turned off. For example, the third set duration is 6 seconds, 8 seconds, or 10 seconds.

[0049] The locking element 20 is connected to the rocker arm 30 in any way to restrict the movement of the rocker arm 30.

[0050] For example, a portion of the rocker arm 30 is recessed to form a locking channel 30a, and the end of the locking member 20 near the rocker arm 30 can be movably inserted into the locking channel 30a. This increases the restraining force of the locking member 20 on the movement of the rocker arm 30, thereby further reducing malfunctions of the self-locking switch caused by accidental contact, vibration, or other factors, and further improving the reliability of the self-locking switch.

[0051] Specifically, the locking channel 30a refers to the channel through which the rocker arm 30 engages with the locking member 20. When the locking member 20 extends into the locking channel 30a, it restricts the movement of the rocker arm 30, thereby locking the self-locking switch. When the locking member 20 exits the locking channel 30a, the rocker arm 30 resumes free movement, thereby unlocking the self-locking switch.

[0052] The shape and size of the locking channel 30a are not limited, as long as it allows the locking element 20 to enter and restricts the movement of the rocker arm 30.

[0053] Understandably, the cross-sectional area of ​​the locking member 20 near the rocker arm 30 gradually increases from the side closest to the rocker arm 30 to the side furthest from the rocker arm 30. This facilitates the smooth entry of the locking member 20 into the locking channel 30a, and the gradually increasing cross-sectional area ensures a good locking effect as the locking member 20 moves deeper, thus improving operational efficiency and reducing the risk of damage from collisions between components.

[0054] The self-locking switch of this embodiment includes a housing 10, a locking member 20, and a rocker arm 30. The housing 10 has a receiving cavity, and at least a portion of the rocker arm 30 is located within the receiving cavity. The self-locking switch has a locked state and an unlocked state. When the self-locking switch is in the locked state, the locking member 20 is connected to the rocker arm 30 to restrict the movement of the rocker arm 30. When the self-locking switch is in the unlocked state, the locking member 20 is separated from the rocker arm 30 to prevent the movement of the rocker arm 30. The locking member 20 is movably disposed within the receiving cavity to allow the self-locking switch to switch between the locked and unlocked states. Thus, on the one hand, in the locked state, the rocker arm 30 is effectively restricted by the locking member 20, which can greatly reduce the malfunction of the self-locking switch caused by accidental contact, vibration, etc., thereby improving the reliability of the self-locking switch. On the other hand, in the unlocked state, the locking member 20 is separated from the rocker arm 30, and the rocker arm 30 can move freely to achieve switching between different modes, thereby improving the practicality of the self-locking switch and meeting the diverse needs of users in different scenarios.

[0055] In one embodiment, please refer to Figure 2 , Figure 6 and Figure 7 The self-locking switch also includes a slider 40, which is located on one side of the locking member 20 along a first direction perpendicular to the extending direction of the locking member 20. When the self-locking switch is in the locked state, the slider 40 abuts against the locking member 20 to restrict the movement of the locking member 20 away from the rocker arm 30. Along the first direction, the slider 40 switches between abutting and disengaging from the locking member 20 by sliding. Thus, by setting the slider 40 to restrict the movement of the locking member 20, the risk of the locking member 20 failing to lock the rocker arm 30 due to loosening or displacement of the locking member 20 is reduced.

[0056] Specifically, the slider 40 refers to the component that can restrict the movement of the locking component 20 away from the rocker arm 30.

[0057] It should be noted that when the self-locking switch is in the locked state, the locking member 20 extends into the locking channel 30a of the rocker arm 30, restricting the movement of the rocker arm 30. At this time, the sliding member 40 abuts against the locking member 20, restricting the locking member 20 from moving to the side away from the rocker arm 30. Therefore, even when the self-locking switch is subjected to accidental activation, vibration, or other factors, the locking member 20 remains within the locking channel 30a, thus keeping the self-locking switch in the locked state and improving its reliability.

[0058] When the self-locking switch is in the locked state, the side of the slider 40 near the rocker arm 30 abuts against the locking member 20 to restrict the movement of the locking member 20 away from the rocker arm 30.

[0059] The size and shape of the slider 40 are not limited, as long as it can move in the first direction and switch between contacting and separating from the locking member 20.

[0060] The manner in which the locking member 20 abuts against the sliding member 40 is not limited.

[0061] For example, please refer to Figure 4 A portion of the locking member 20 protrudes towards the side closer to the sliding member 40 to form a first protrusion 21. When the self-locking switch is in the locked state, the first protrusion 21 abuts against the side of the sliding member 40 closer to the rocker arm 30. This allows for a better abutment between the locking member 20 and the sliding member 40, thereby enabling the sliding member 40 to better restrict the movement of the locking member 20 away from the rocker arm 30.

[0062] Specifically, the first protrusion 21 refers to the part where the locking member 20 abuts against the sliding member 40 when the self-locking switch is in the locked state.

[0063] The shape of the first protrusion 21 is not limited.

[0064] For example, the first protrusion 21 has a first side on the side away from the rocker arm 30 and a second side on the side near the rocker arm 30. The first side extends along a first direction from the side away from the slider 40 to the side near the slider 40. The second side is inclined toward the side away from the rocker arm 30. When the self-locking switch is in the locked state, the first side abuts against the slider 40.

[0065] Specifically, the first side extends along a first direction, that is, the first side is perpendicular to the extension direction of the locking member 20. Thus, when the self-locking switch is in the locked state, the first protrusion 21 and the sliding member 40 have a good abutment effect, thereby effectively restricting the movement of the locking member 20 away from the rocker arm 30.

[0066] It should be noted that when the self-locking switch is in the locked state, the first side abuts against the slider 40, and the slider 40 is located on the side of the first protrusion 21 opposite to the rocker arm 30. When switching from the locked state to the unlocked state, the locking member 20 moves towards the side opposite to the rocker arm 30, so that the position of the slider 40 changes from the side of the first protrusion 21 opposite to the rocker arm 30 to the side of the first protrusion 21 closer to the rocker arm 30. During the process of the self-locking switch switching from the unlocked state back to the locked state, the locking member 20 moves towards the side closer to the rocker arm 30. At this time, the second side abuts against the slider 40. Due to the inclined setting of the second side, the second side can push the slider 40 towards the side opposite to the locking member 20 until the slider 40 is once again located on the side of the first protrusion 21 opposite to the rocker arm 30, and the first side abuts against the slider 40 again, and the self-locking switch is locked again.

[0067] Please see Figure 4Another portion of the locking member 20 protrudes towards the side near the sliding member 40 to form a second protrusion 22. As the locking member 20 moves towards the rocker arm 30, the second protrusion 22 abuts against the side of the sliding member 40 away from the rocker arm 30, pushing the sliding member 40 away from the locking member 20 to separate the locking member 20 and the sliding member 40. Thus, the user can switch the self-locking switch from the locked state to the unlocked state simply by pressing the locking member 20 towards the rocker arm 30, simplifying the operation and improving the ease of use of the self-locking switch.

[0068] Specifically, the second protrusion 22 refers to a component that abuts against the slider 40 to move the slider 40 toward the side away from the locking member 20, thereby separating the locking member 20 from the slider 40.

[0069] In one embodiment, please refer to Figure 4 and Figure 5 The sliding member 40 has a first abutment surface 41 on the side near the second protrusion 22. From the side away from the locking member 20 to the side near the locking member 20, the first abutment surface 41 is inclined towards the side near the rocker arm 30. The locking member 20 has a second abutment surface 221, which is parallel to the first abutment surface 41. During the movement of the locking member 20 towards the rocker arm 30, the first abutment surface 41 and the second abutment surface 221 abut against each other. Thus, by setting the second abutment surface 221 parallel to the first abutment surface 41, and by abutting the first abutment surface 41 and the second abutment surface 221 to push the locking member 20 towards the side away from the locking member 20, the force transmission between the locking member 20 and the sliding member 40 is more uniform, reducing the risk of wear or deformation of the components due to local stress concentration in the locking member 20 and the sliding member 40.

[0070] In one embodiment, please refer to Figure 7 The housing 10 includes a first sidewall 11, a portion of which is open to form a first channel 11a. The first channel 11a extends along the extension direction of the locking member 20. A rocker arm 30 is movably disposed within the first channel 11a along its extension direction. Thus, the rocker arm 30 can move along the extension direction of the first channel 11a to switch between different modes, thereby improving the practicality of the self-locking switch and meeting the diverse needs of users in different scenarios.

[0071] Specifically, the movement of the joystick 30 relative to the first channel 11a is not limited.

[0072] For example, the joystick 30 can move along the extension direction of the first channel 11a.

[0073] For example, the joystick 30 can be deflected along the extension direction of the first channel 11a.

[0074] In one specific embodiment, the docking station includes a control system. The docking station is connected to an external display, and the control system is signal-connected to a processor. When the self-locking switch is in the unlocked state, and the rocker arm 30 is deflected along the extension direction of the first channel 11a after being pressed down, the processor receives the signal and transmits it to the control system. The control system then drives the external display to enter the contrast adjustment mode.

[0075] In one embodiment, please refer to Figure 7 The housing 10 includes a first sidewall 11, with another portion of the first sidewall 11 open to form a second channel 11b. The second channel 11b extends along a first direction. A rocker arm 30 is movably disposed within the second channel 11b along the extending direction of the second channel 11b. The first direction is perpendicular to the extending direction of the locking member 20. Thus, the rocker arm 30 can move along the extending direction of the second channel 11b to switch between different modes, thereby further enhancing the practicality of the self-locking switch and meeting the diverse needs of users in different scenarios.

[0076] Specifically, the movement of the joystick 30 relative to the second channel 11b is not limited.

[0077] For example, the joystick 30 can move along the extension direction of the second channel 11b.

[0078] For example, the joystick 30 can be deflected along the extension direction of the second channel 11b.

[0079] In one specific embodiment, the docking station includes a control system. The docking station is connected to an external display, and the control system is signal-connected to a processor. When the self-locking switch is in the unlocked state, and the joystick 30 is deflected along the extension direction of the second channel 11b after being pressed down, the processor receives the signal and transmits it to the control system. The control system then drives the external display to enter the brightness adjustment mode.

[0080] In one embodiment, please refer to Figure 7 The housing 10 has a first opening 10a, and the locking member 20 is movably inserted into the first opening 10a. A portion of the locking member 20 protrudes along a first direction to form an abutment portion 23. The abutment portion 23 is located on the side of the locking member 20 closest to the first opening 10a, and the cross-sectional dimension of the abutment portion 23 is larger than the cross-sectional dimension of the first opening 10a. The first direction is perpendicular to the extension direction of the locking member 20. This makes the connection between the locking member 20 and the housing 10 more secure, effectively preventing the locking member 20 from accidentally loosening or shifting, and improving the reliability of the self-locking switch.

[0081] Specifically, the size and dimensions of the first opening 10a are not limited. As long as the locking member 20 can pass through the first opening 10a and move relative to the first opening 10a, it is acceptable.

[0082] The abutting part 23 refers to the part that abuts against the housing 10 at the first opening 10a to prevent the locking member 20 from dislodging from the receiving cavity.

[0083] The formation method of the contact part 23 is not limited.

[0084] For example, a portion of the locking member 20 protrudes towards the side closer to the elastic member 50 to form an abutment portion 23. That is, the locking member 20 has an abutment portion 23 only on the side closer to the elastic member 50.

[0085] For example, a portion of the locking member 20 protrudes circumferentially to form an abutment portion 23. That is, the locking member 20 does not only have the abutment portion 23 on the side closest to the elastic member 50; the abutment portion 23 is located circumferentially around the locking member 20. This further prevents the locking member 20 from dislodging from the receiving cavity, further improving the reliability of the self-locking switch.

[0086] In one embodiment, please refer to Figure 7 The self-locking switch also includes an elastic element 50, and the housing 10 further has a receiving groove 10b located within the receiving cavity and on the side of the abutment portion 23 opposite to the first opening 10a. At least a portion of the elastic element 50 is located within the receiving groove 10b, with one end abutting against the groove wall of the receiving groove 10b on the side opposite to the first opening 10a, and the other end abutting against the abutment portion 23. By applying an elastic force to the abutment portion 23 through the elastic element 50, on the one hand, in the locked state, the elastic force can continuously act, maintaining a stable abutment effect between the locking member 20 and the sliding member 40, effectively preventing the locking member 20 from separating from the sliding member 40 due to external vibration, equipment shaking, or accidental contact, thereby allowing the self-locking switch to switch from the locked state to the unlocked state. On the other hand, in the unlocked state, the supporting force provided by the elastic element 50 can counteract the movement tendency of the locking member 20 due to gravity and other factors, preventing the locking member 20 from falling back into the locking channel 30a and preventing it from accidentally restricting the movement of the rocker arm 30. Therefore, the reliability of the self-locking switch is further improved by setting the elastic element 50.

[0087] Specifically, the structure of the elastic element 50 is not limited.

[0088] For example, the elastic element 50 is a spring.

[0089] The receiving groove 10b refers to the component used to receive the elastic member 50 and to ensure that the elastic member 50 and the abutment portion 23 can effectively cooperate.

[0090] It should be noted that when the self-locking switch is in the locked state, the elastic element 50 abuts against the abutting part 23 so that the first abutting part 23 and the sliding element 40 have a good abutting effect, which can effectively prevent the locking element 20 and the sliding element 40 from separating due to external vibration, equipment shaking or accidental contact.

[0091] When the locking member 20 moves towards the side closer to the rocker arm 30, the second protrusion 22 abuts against the sliding member 40, pushing the sliding member 40 away from the locking member 20. Then, the pressing force of the locking member 20 is released, and the elastic member 50 releases its elastic force, causing the locking member 20 to move away from the rocker arm 30, so that the position of the sliding member 40 changes from the side of the first protrusion 21 away from the rocker arm 30 to the side of the first protrusion 21 closer to the rocker arm 30. The locking member 20 disengages from the locking channel 30a, and the self-locking switch enters the unlocked state.

[0092] In one specific embodiment, a portion of the abutment portion 23 near the rocker arm 30 protrudes towards one side of the rocker arm 30 to form a limiting portion 231, which passes through the elastic member 50. This limits the displacement of the elastic member 50, ensuring it always moves along its extension direction, reducing elastic force loss and component wear caused by lateral bending or twisting of the elastic member 50, and improving its working efficiency and service life.

[0093] The shape of the limiting part 231 is not limited.

[0094] For example, the limiting part 231 is cylindrical.

[0095] In the description of this application, the references to terms such as "in one embodiment," "in some embodiments," "in a specific embodiment," or "exemplary," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of the embodiments of this application. In this application, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example.

Claims

1. A self-locking switch, characterized in that, include: A housing having a receiving cavity; Locking element; A rocker arm, at least a portion of which is located within the receiving cavity; The self-locking switch has a locked state and an unlocked state. When the self-locking switch is in the locked state, the locking member is connected to the rocker arm to restrict the movement of the rocker arm. When the self-locking switch is in the unlocked state, the locking member is separated from the rocker arm to prevent the movement of the rocker arm. The locking element is movably disposed within the receiving cavity so that the self-locking switch switches between the locked state and the unlocked state.

2. The self-locking switch according to claim 1, characterized in that, The self-locking switch further includes a slider located on one side of the locking member along a first direction, the first direction being perpendicular to the extending direction of the locking member. When the self-locking switch is in the locked state, the slider abuts against the locking member to restrict the locking member from moving away from the rocker arm. Along the first direction, the slider switches between abutting and disengaging from the locking member by sliding.

3. The self-locking switch according to claim 2, characterized in that, A portion of the locking member protrudes towards the side closer to the sliding member to form a first protrusion. When the self-locking switch is in the locked state, the first protrusion abuts against the side of the sliding member closer to the rocker arm.

4. The self-locking switch according to claim 2, characterized in that, Another portion of the locking member protrudes towards the side closer to the sliding member to form a second protrusion. As the locking member moves towards the rocker arm, the second protrusion abuts against the side of the sliding member away from the rocker arm to push the sliding member away from the locking member, thereby separating the locking member and the sliding member.

5. The self-locking switch according to claim 4, characterized in that, The slider has a first abutting surface on the side near the second protrusion. From the side away from the locking member to the side near the locking member, the first abutting surface is inclined toward the side near the rocker arm. The locking member has a second abutting surface, which is parallel to the first abutting surface. During the movement of the locking member toward the rocker arm, the first abutting surface abuts against the second abutting surface.

6. The self-locking switch according to any one of claims 1-5, characterized in that, A portion of the rocker arm is recessed to form a locking channel, and the locking member can be movably inserted into the locking channel at one end near the rocker arm.

7. The self-locking switch according to any one of claims 1-5, characterized in that, The housing includes a first sidewall; A portion of the first sidewall is open to form a first channel, the first channel extending along the extension direction of the locking member, and the rocker arm is movably disposed within the first channel along the extension direction of the first channel; And / or, Another portion of the first sidewall is open to form a second channel extending in a first direction. Along the extension direction of the second channel, the rocker arm is movably disposed within the second channel, and the first direction is perpendicular to the extension direction of the locking member.

8. The self-locking switch according to any one of claims 1-5, characterized in that, The housing has a first opening, and the locking member is movably inserted into the first opening.
