Detailed Implementation

[0025] To more clearly illustrate the technical solutions in the embodiments of this utility model and / or the prior art, the specific implementation methods of this utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are merely some embodiments of this utility model. For those skilled in the art, other drawings and other implementation methods can be obtained based on these drawings without creative effort. Furthermore, references to orientation only indicate the relative positional relationship between the components, not their absolute positional relationship.

[0026] Please see Figures 1 to 9 As shown, a safety switch for an automotive charging socket includes a push switch 1 and a locking member 2. The push switch 1 is provided with a switch action component, and the locking member 2 is provided with a sliding linkage structure between the switch action component and the switch action component. When the switch action component keeps the internal circuit of the push switch 1 on or off, the sliding linkage structure locks or locks the locking end of the locking member 2 to the external plug.

[0027] In this embodiment, the sliding linkage structure includes a push groove 3, a push block 4, a first elastic element 5, a locking element 6, and a locking block 7. The first elastic element 5 enables the push block 4 and the push groove 3 to engage in a pushing fit, so that the latch 2 can move laterally when the switch actuation component is activated. The locking element 6 and the locking block 7 can lock or lock. When the locking element 6 and the locking block 7 are locked, the locking end of the latch 2 locks the external plug accordingly. When the locking element 6 and the locking block 7 are locked, the locking end of the latch 2 locks the external plug accordingly. More specifically, the push groove 3 and the push block 4 are respectively located between the switch actuation component and the latch 2. The push groove 3... The upper side wall is set as the first pushing slope, and the corresponding wall of the pushing block 4 is set as the second pushing slope. At the same time, the pushing block 4 will extend into the pushing groove 3, and the second pushing slope will abut against the first pushing slope. One end of the first elastic member 5 is connected to the button switch 1, and the other end of the first elastic member 5 will be connected to the locking member 2. It should be noted that a connecting post is set on the outside of the button switch 1 relative to the switch action component, and a connecting post is also set on the locking member 2. The two ends of the first elastic member 5 are respectively engaged with the connecting post. The first elastic member 5 provides the force for the pushing block 4 and the pushing groove 3 to push against each other, so that the locking member 2 can achieve the purpose of lateral movement. The first elastic member 5 is a spring.

[0028] In this embodiment, the locking member 6 is a locking hook, and the locking block 7 is formed in the limiting recess 9 of the limiting seat 8. The locking block 7 is formed on the switch action assembly. A guide block 10 is also provided above the locking block 7 in the limiting recess 9. The locking end of the locking member 6 locks or closes with the locking block 7 under the action of the guide block 10. The specific principle of locking or closing the locking member 6 and the locking block 7 is existing technology and will not be detailed here. However, by using this method, after cooperating with the push groove 3, the push block 4 and the first elastic member 5, the lock is engaged when the external plug has not yet been inserted. The locking end of component 2 is already in the locked state, and the locking component 6 and the locking block 7 are also in the locked state. That is, the internal circuit of the push button switch 1 is connected, and the switch action component has completed its action. At this time, an external plug can also be inserted. More specifically, because the locking component 6 and the locking block 7 can achieve locking, in conjunction with the push groove 3, the push block 4 and the first elastic component 5, the locking component 2 can be reset to achieve locking. Under the above conditions, in order to make it easier for the external plug to drive the locking component 2 to move, the locking end of the locking component 2 can be set as an inclined surface.

[0029] In this embodiment, the switch actuation assembly includes a first pressing member 11. The first pressing member 11 has first mounting holes on both sides. The push-button switch 1 has a first mounting protrusion 12, which is positioned relative to the outside of the switch actuation assembly. The first pressing member 11 slides vertically and is limited by the first mounting protrusion 12. The first mounting protrusion 12 also has a second elastic member 13, which abuts against the first pressing member 11. More specifically, the head of the first mounting protrusion 12 is a cylindrical first elastic snap-fit ​​connector. During installation, the first elastic snap-fit ​​connector retracts and passes through the first mounting hole, and then the first elastic snap-fit ​​connector is reset to form an anti-dislodgement restriction on the first pressing member 11. At the same time, the second elastic member 13 is also a spring. When the first pressing member 11 moves down, the second elastic member 13 will compress and deform to accumulate elastic potential energy. When resetting, the second elastic member 13 will release the elastic potential energy, thereby enabling the first pressing member 11 to reset quickly. This also avoids the first elastic member 5 from experiencing elastic fatigue too quickly, resulting in good performance, long service life, and reasonable structural design.

[0030] In this embodiment, the switch action assembly further includes a second pressing member 14, which is integrally installed with the first pressing member 11 and is disposed over the first pressing member 11. A push block 4 is formed on the second pressing member 14, and a push groove 3 is formed on the locking member 2. A mounting cavity can be provided on the second pressing member 14. A latch and a locking block can be provided between the mounting cavity and the first pressing member 11. The second pressing member 14 and the first pressing member 11 are integrally installed through the cooperation of the latch and the locking block. The combination of the second pressing member 14 and the first pressing member 11 facilitates injection molding.

[0031] In this embodiment, the second pressing member 14 is also provided with a mounting plate 15, and the mounting plate 15 is provided with a mounting slot. The extension length of the mounting slot is adapted to the pressing stroke of the second pressing member 14. The pressing switch 1 is also provided with a first locking member 16, which is disposed relative to the outside of the switch action component. The hook part of the first locking member 16 is engaged in the mounting slot. Through the cooperation between the first locking member 16 and the mounting plate 15, the second pressing member 14 is less likely to fall out when it is reset, thus forming an effective constraint on the second pressing member 14 and making the installation and cooperation more reasonable.

[0032] In this embodiment, the safety switch 35 also includes a circuit board 17 with an indicator light. The circuit board 17 is fixedly installed on the bottom of the first pressing member 11. The circuit board 17 draws power from the push switch 1. By setting the circuit board 17 with an indicator light, the safety switch 35 can be adapted to be used in darker environments or to display the working status of the push switch 1, according to the user's requirements. It has a wider range of applications and a reasonable structural design.

[0033] In this embodiment, the switch action assembly is provided with a guide protrusion 18, and the push switch 1 is also provided with a guide recess 19. The guide recess 19 is arranged opposite to the switch action assembly. The guide protrusion 18 and the guide recess 19 cooperate with each other. The guide protrusion 18 and the guide recess 19 are arranged in pairs, and the guide protrusion 18 and the guide recess 19 slide in cooperation. This arrangement makes the up and down movement of the first pressing member 11 and the second pressing member 14 more stable and has a better effect.

[0034] In this embodiment, the push switch 1 is also provided with a sliding cavity 20. The front end of the sliding cavity 20 is through-hole, and the bottom wall of the sliding cavity 20 is also provided with a second locking member 21. The locking end of the locking member 2 cooperates with the sliding cavity 20. The locking end of the locking member 2 is provided with a through mounting groove 22. The through mounting groove 22 extends along the sliding direction of the locking member 2, and the extension length of the through mounting groove 22 is adapted to the sliding stroke of the locking member 2. The hook part of the second locking member 21 passes through the through mounting groove 22 and is slidably limited and connected to the locking member 2. By adopting the cooperation method of the sliding cavity 20 and the locking end of the locking member 2, the sliding of the locking member 2 is more reasonable. Through the cooperation of the second locking member 21 and the through mounting groove 22, the locking member 2 is effectively installed without affecting the sliding of the locking end of the locking member 2. At the same time, a support plate is also provided on the push switch 1, and the locking member 2 will also be supported and slid on the support plate.

[0035] In this example, the switch actuation assembly also includes a third pressing member 23 and a rotating member 24. The rotating member 24 is a rotor. The push-button switch 1 also includes a cover 25, a conductive base 26, a third elastic member 27, a fourth elastic member 28, and a base 29. The cover 25 has a through hole 30 at its center. The third pressing member 23 is axially moved through the through hole 30 and is pressed and engaged with the first pressing member 11 and the second pressing member 12. The rotating member 24 is engaged with the lower end of the third pressing member 23 and rotates circumferentially under the drive of the third pressing member 23. The conductive base 26 is inserted through the lower end of the rotating member 24. The third elastic member 27 is installed between the conductive base 26 and the rotating member 24. The fourth elastic member 28 is connected to the rotating member 29. Between 4 and base 29, base 29 is fixed to the lower end of cover 25. At least two first conductive elements 31 are provided on base 20. The first conductive elements 31 are contacted and connected by conductive seat 26. More specifically, the third elastic element 27 and the fourth elastic element 28 are both springs. The third elastic element 27 enables the conductive seat 26 to stably connect the first conductive elements 31. The fourth elastic element 28 enables the rotating element 24 and the third pressing element 23 to cooperate stably and reliably. The first conductive elements 31 can be a pair or two pairs. A second conductive element can also be provided on conductive seat 26. The two ends of the second conductive element can cooperate with the corresponding first conductive element 31, thereby improving the conductivity. Base 29 and cover 25 are assembled by snap-fit ​​connection.

[0036] In this example, the rotating member 24 is provided with a convex ring that abuts against the lower end of the third pressing member 23. The upper end face of the convex ring and the lower end face of the third pressing member 23 are provided with meshing connecting teeth. The inner wall of the through hole 30 is provided with a switch disconnection limiting groove and a switch connection limiting groove. The lower ends of the switch disconnection limiting groove and the switch connection limiting groove penetrate through the through hole 20. The upper end face of the switch disconnection limiting groove is lower than the upper end face of the switch connection limiting groove. The convex rings of the third pressing member 23 and the rotating member 24 are respectively provided with radial ribs that slide into the switch disconnection limiting groove or the switch connection limiting groove. When the first pressing member 11 and the second pressing member 14 act on the third pressing member 23... Under the action of the meshing connecting teeth, the rotating part 24 will rotate together, so that the radial rib on it will slide into the switch disconnection limit groove or the switch connection limit groove. When the radial rib is located in the switch disconnection limit groove through rotation, under the action of the fourth elastic element 28, the rotating part 24 will drive the conductive seat 26 to move upward, thereby keeping it separated from the first conductive element 31, and the switch will be disconnected. When the radial rib is located in the switch connection limit groove through rotation, the third pressing element 23 will cause the rotating part 24 to drive the conductive seat 26 to move downward, and cause the fourth elastic element 28 to compress and accumulate elastic potential energy, keeping it in contact with the first conductive element 31, and the switch will be connected.

[0037] In this example, the lower end of the rotating member 24 is provided with a second mounting protrusion 32. The limit for the vertical sliding of the conductive seat 26 is provided through the second mounting protrusion 32. The head of the second mounting protrusion 32 is also provided with a cavity. The fourth elastic member 28 is provided in the cavity. At the same time, a cylindrical second elastic snap connector is provided at the lower end of the rotating member 24. The conductive seat 26 is provided with a second mounting through hole. During installation, the second elastic snap connector is contracted and passes through the second mounting through hole. Then, the second elastic snap connector is reset to form an anti-detachment limit for the conductive seat 26. At the same time, a cavity is formed around the second mounting through hole at the upper end of the conductive seat 26. The lower end of the third elastic member 27 is placed in the cavity to form a support for the conductive seat 26.

[0038] In this embodiment, the connecting post, the first mounting protrusion 12, the first locking member 16, the guide recess 19, the sliding cavity 20, the second locking member 21, the support plate, and the through hole 30 are all formed on the cover 25. More specifically, the cover 25 also has a mounting base 33 that cooperates with the locking member 6. The mounting end of the locking member 6 cooperates with the mounting base 33. At the same time, a fifth elastic member 34 is provided between the mounting base 33 and the limiting seat 8. The fifth elastic member 34 is also a spring.

[0039] In this embodiment, the cover 27 is also provided with a fixing part, and the fixing part is provided with a fixing through hole for installing fixing screws.

[0040] Working principle: Pressing the second pressing member 14 causes it to move downwards, which in turn moves the push block 4 downwards. Under the action of the first elastic member 5, the push groove 3, and the sliding cavity 20, the locking member 2 moves in the locking direction, and the second pressing member 14 is pressed into place. The third pressing member 23 then connects the conductive base 26 to the conductive element, and the button switch 1 supplies power to the car charging socket 36. At the same time, the locking member 2 locks with the external plug, and the locking member 6 locks with the locking block 7. Pressing the second pressing member 14 again locks the locking member 6 and the locking block 7. The third pressing member 23 moves upwards, causing the second pressing member 14 to move upwards as well. The locking member 6 and the locking block 7 lock, and under the action of the first elastic member 5, the push groove 3, and the sliding cavity 20, the locking member 2 moves upwards. 2. Move towards the locking direction, the third pressing part 23 resets, the locking part 6 resets, the locking part 2 locks with the external plug, and when the external plug is not inserted, the locking end of the locking part 2 is already in the locked state, and the locking part 6 and the locking block 7 are already in the locked state, that is, the internal circuit of the push button switch 1 is connected, the switch action component has completed the action, and the external plug can be inserted at this time. More specifically, the insertion of the external plug can also make the locking part 2 move towards the locking direction, and can also make the locking part 6 and the locking block 7 lock. With the cooperation of the push groove 3, the push block 4 and the first elastic part 5, the locking part 2 can be reset, and the locking part 6 can be reset. At this time, just repeat the above actions to lock the external plug again.

[0041] In summary, this utility model can achieve the purpose of manually controlling the circuit on and off of the car charging socket 36, and can lock the external plug after insertion, thereby improving the reliability of the charging connection, making it less prone to loosening, effectively ensuring service life, and the external plug can be inserted whether the circuit is on or off, but the switch needs to be off when pulling it out, making it safer to use.

[0042] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, various simple deductions or substitutions can be made without departing from the concept of the present invention, and all such modifications and substitutions should be considered within the protection scope of the present invention.
