Next, after power-on, the switch must be prevented from turning off in order to maintain the normally-on state of the circuit. However, in the process of daily life, a user inevitably contacts or operates the switch carelessly, so that the intelligent device is easily powered off accidentally.

Furthermore, in consideration of the situation that the intelligent device does not need to be in a long-term circuit normally-on state under the conditions of energy conservation or long-term use-free and the like, the switch device is required to be capable of smoothly switching in an on-off state, namely the switch is required to be capable of switching between a flash mode and a common switch mode. However, the switch on the market at present mainly meets the function of long-term power-on of a circuit by simply adding a return spring on the traditional switch, and the switch with the structure cannot flexibly switch the common mode and the flash mode of the switch. In addition, the conventional switch device is inconvenient in operation mode switching operation, and the operation mode is easy to automatically switch or fail.

Fig. 2 and 3 show the structure of the switching device from different top views.

As shown in fig. 1, 2 and 3, the present invention provides a switchgear having a bottom case 1, a reset mechanism 2 and a front panel 3.

As shown in fig. 1 and 6, the bottom case 1 has a mounting cavity 101, and a switch pressing plate 11, a dial block 12, and a seesaw 13 are disposed in the mounting cavity 101.

Referring to fig. 5 and 6, the seesaw 13 is rotatably mounted to the inner bottom surface of the mounting chamber 101 by a rotating member. When the seesaw 13 is driven to reciprocate towards two sides, the power-on state of the switch device can be changed, namely the switch device can be driven to be switched between the power-on state and the power-off state.

Referring to fig. 1, 2, 3 and 4, the switch pressing plate 11 is installed in the installation cavity 101. Specifically, the switch pressing plate 11 is fixed by a shape fit with the mounting cavity 101, for example, in the present embodiment, the switch pressing plate 11 is supported and mounted by a stepped structure in the mounting cavity 101. In other embodiments, the switch pressure plate 11 can be mounted or fixed by other means, such as a snap fit or a bolt.

As shown in fig. 2, 3, 5 and 6, the switch holding plate 11 is provided with a swing groove 111 penetrating the thickness thereof, a support wall 112 located at the opposite side of the swing groove 111, and a mounting groove 102 located at the periphery of the swing groove 111.

Referring to fig. 4, 6 and 7, the toggle block 12 is mounted on the switch pressing plate 11, and the toggle block 12 can swing back and forth relative to the switch pressing plate 11. Referring to fig. 2, 3 and 4, the top of the dial 12 is rotatably mounted on the supporting wall 112, and the bottom of the dial 12 is swingably disposed in the swing groove 111. In practical implementation, the dial block 12 may be connected to the supporting wall 112 through a rotation pair such as a rotating shaft or a latch.

Referring to fig. 6 and 7, the bottom of the dial block 12 passes through the swing slot 111 and contacts with the seesaw 13 located on the inner bottom surface of the mounting cavity 101. Therefore, when the dial 12 swings or reciprocates, the state of the seesaw 13 moving to both sides can be adjusted.

Referring to fig. 6 and 7, the toggle block 12 can perform a reciprocating deflecting motion on the surface of the switch pressing plate 11 along the left side or the right side of the figure, and the reciprocating swing of the toggle block 12 can drive the seesaw 13 to move correspondingly. Thus, by adjusting the reciprocating movement of the toggle block 12, the state of the switch can be adjusted.

As shown in fig. 1, 4, 6 and 7, the front panel 3 is mounted on the top of the toggle block 12 and can drive or follow the toggle block 12 to perform a reciprocating motion for switching a switch state. That is, the reciprocating motion of the front panel 3 and the dial block 12 is synchronized.

Based on the above structural arrangement: on one hand, the deflection motion or the reciprocating motion of the front panel 3 can be transmitted to the seesaw 13 through the action of the toggle block 12, and the motion state or the position of the seesaw 13 is adjusted to realize the function of switching the switch state; on the other hand, the motion state or position of the seesaw 13 can be adjusted by adjusting the motion state of one of the dial block 12 or the front panel 3, so as to realize the function of switching the switch state.

In practical implementation, the front panel 3 may be connected to the top surface of the toggle block 12 through a connection leg, a hook, or a slot disposed on the bottom surface thereof. Through adopting detachable mounting means, can be to switching device's spare part is replaced, the increase of service life.

Of course, the reciprocating motion of the front panel 3 is not limited to the form of deflection along the left and right sides of the toggle block 12 shown in fig. 4 and 6, and other forms such as the front panel 3 can move up and down vertically relative to the switch pressing plate 11 are also feasible.

It is right above the switching device of the present invention how to switch the on/off state is explained in detail. The reset mechanism 2 will be further explained with reference to the schematic structural diagrams of the switching device shown in fig. 4-8 in various operating modes.

As shown in fig. 2 and 3, the reset mechanism 2 is disposed in the mounting groove 102 of the switch holding plate 11. As can be seen with further reference to fig. 1 and 4, the return mechanism 2 includes an elastic member 21, a locking member 22, and a positioning member 23.

Referring to fig. 6 and 7, the elastic member 21 is vertically disposed in the mounting groove 102. The elastic member 21 is a main structure for performing a telescopic motion, generating a resilient force, and supporting the locking member 22.

Specifically, the inner bottom surface of the mounting groove 102 is provided with a mounting protrusion 103, and the elastic member 21 is sleeved on the mounting protrusion 103. In practical applications, the elastic member 21 may be a spring, an elastic sheet, or other members capable of generating elastic deformation.

As shown in fig. 5, 6 and 7, the lock member 22 is attached to the top of the elastic member 21, and the lock member 22 is movable between a first position and a second position.

Referring to fig. 6 and 7, when the locking member 22 is in the first position, the locking member 22 is coupled to the front panel 3, and the locking member 22 is misaligned with the positioning member 43. Accordingly, at this time, the reset mechanism 2 can always return the front panel 3 to the power-on state in the reciprocating motion.

In this embodiment, the locking member 22 is coupled to the front panel 3 through the toggle block 12. In other embodiments, the locking member 22 may be directly coupled to the front panel 3, which is not limited by the present invention.

As shown in fig. 6, when the front panel 3 is pressed or adjusted to turn off the switch device, the toggle block 12 vertically compresses the locking member 22, and the elastic member 21 supporting the locking member 22 is compressed to generate a resilient force. Then, referring to fig. 7, under the action of the resilience force generated by the elastic member 21, the locking member 22 will drive the toggle block 12 and the front panel 3 to automatically return to the position of the power-on state during the movement process.

It should be noted that, as shown in fig. 6 and 7, due to the misalignment between the locking member 22 and the positioning member 43, the telescopic movement of the locking member 22 at the first position is not affected by the positioning member 43. For example, in the present embodiment, when the locking member 22 is in the first position, the locking member 22 is disposed in a vertically and circumferentially offset manner with respect to the positioning member 23.

As shown in fig. 4, 5 and 8, when the locking member 22 is at the second position, the locking member 22 is retracted from the front panel 3, and the locking member 22 is aligned and engaged with the positioning member 23. Correspondingly, the reset mechanism 2 is locked at a position far away from the front panel 3 and the toggle block 12 and is in a self-locking state.

Referring to fig. 4, 5 and 8, at this time, the locking member 22 cannot contact with the dial block 12 or cannot be coupled to the dial block 12, so that the resilience of the elastic member 21 cannot be transmitted to the dial block 12. And the toggle block 12 loses the resilience support of the reset mechanism 2 in the reciprocating motion process, and can not be reset to the position where the switch device is in the power-on state by the user. Accordingly, at this time, the power-on state or the power-off state of the switch can be adjusted by adjusting the position of the front panel 3, that is, the switching device is in the normal switching mode at this time.

Since the locking member 22 and the positioning member 23 are configured to be aligned and engaged, the structures of the locking member 22 and the positioning member 23 will be explained below.

As shown in fig. 1, 6, and 7, the lock member 22 includes a mounting portion 221 and a lock portion 222. The bottom of the mounting portion 221 has a protrusion, and the elastic member 21 is sleeved on the protrusion. The locking portion 222 is located at an outer periphery of the mounting portion 221, and is engaged with the positioning member 23.

As shown in fig. 1, the locking member 22 further sets the thickness of the locking portion 222 to be smaller than the thickness of the mounting portion 221, so that the height of the locking portion 222 is smaller than the height of the mounting portion 221. With such an arrangement, when the locking portion 222 is toggled, the locking portion 222 can easily enter into the circumferential region of the positioning member 23 to be aligned and clamped.

As shown in fig. 4 and 5, the positioning member 43 is disposed on a side wall of the mounting groove 102, and the positioning member 43 is configured to be capable of being engaged and fixed with the locking member 42.

Referring to fig. 4 and 5, a first locking portion 251 is formed on the locking portion 222, and a second locking portion 252 is formed on the positioning member 23. When said lock 22 is in said second position: the first latching portion 251 and the second latching portion 252 are matched to fix the locking member 22 at the positioning member 23.

As shown in fig. 2, 5 and 8, in this embodiment, the first latching portion 251 is the locking groove 223 disposed on the locking portion 222, the second latching portion 252 is the locking protrusion 231 formed on the positioning member 23, and when the locking member 22 is at the second position, the locking protrusion 231 is locked into the locking groove 222.

In other embodiments, the first locking portion 251 may have a groove structure, and correspondingly, the second locking portion 252 has a protrusion structure. It should also be noted that the positioning member 23 may be integrally formed with the side wall of the mounting groove 102. For example, as shown in fig. 7, in the present embodiment, the positioning member 23 is a structure that is formed at the bottom of the side rib of the mounting groove 102 and can be used for engagement. The engaging structure may be, but is not limited to, a protrusion or a groove. In other embodiments, the positioning element 23 may also be a member or structure additionally disposed on the side wall of the mounting groove 102, which is not limited in this disclosure.

Obviously, because completion auto-lock state setting element 23 and locking piece 22 set up respectively on switch board 11 and elastic component 21, consequently the utility model discloses reset mechanism 2's auto-lock state is more stable, can not receive the influence of the motion state of front panel 3 or stirring piece 12, therefore the utility model discloses reset mechanism 2 enables switching device stably to maintain at predetermined mode, prevents to take place the automatic switch-over of mode or the condition of inefficacy.

In the specific implementation, in order to improve the performance of the switchgear, an operating mechanism for switching the work position of the reset mechanism 2 may be further provided in the switchgear. As shown in fig. 1 and 2, the operating mechanism 4 includes an operating slot 42 and an operating hole 41.

As shown in fig. 1 and 2, the operation hole 41 is opened on the dial block 12 and penetrates through the thickness of the dial block 12 to expose the dial block 12 of the reset mechanism 2. That is, the operation hole 41 is a through hole provided in the dial block 12.

As shown in fig. 1 and 2, the operation slot 42 is provided on the top surface of the lock member 22 to be exposed through the manipulation hole 41 provided on the dial block 12.

For example, an auxiliary member, such as a small screw, may be passed through the operation hole 41, and the top of the auxiliary member is placed at the operation groove 42, and the operation groove 42 is vertically pressed. When the positioning element 23 pushes the locking element 22 in the vertical direction, the locking element 22 is shifted to enable the first buckling part of the locking part 222 and the second buckling part of the positioning element 23 to be aligned and clamped. Then, the auxiliary member is removed, and the return mechanism 2 is in a self-locking state. If the self-locking state is to be released, the operation is carried out in the opposite mode.

Compare with current switching device, through setting up operating device 4, switching device can only dismantle under the condition of front panel 3 switch canceling release mechanical system 2's station, change over switch's mode has easy operation, and convenient to use's advantage. In addition, the above-described functions can be realized only by adding the operation groove 42 and the operation hole 41, and the number of components of the switchgear is increased.

In order to further increase the operating mode of the switch device, the switch device further comprises a limiting mechanism 5 for limiting the front panel 3.

As shown in fig. 2, 3 and 7, the limiting mechanism 5 is disposed on a side wall of the installation cavity 101, and the limiting mechanism 5 can always keep the front panel 3 at least one preset position. When the front panel 3 is in the preset position, the switch device is in a power-on state or a power-off state. At this time, even if a user accidentally touches or operates the switch, the switch device can be maintained in the power-on state or the power-off state.

As shown in fig. 2 and 3, the limiting mechanism 5 includes an eccentric member 51, a positioning structure 52 and a receiving groove 53.

As shown in fig. 8, the eccentric member 51 is rotatably mounted on the sidewall of the mounting chamber 101 and has a large end capable of protruding from the inner surface of the sidewall. The receiving groove 53 is also opened on the side wall of the mounting cavity 101, and can be used for receiving the large end of the eccentric member 51.

For example, as shown in fig. 8, in the present embodiment, a stepped structure is formed on a side wall of the mounting cavity 101, the eccentric member 51 is mounted on a vertically extending portion of the stepped structure, and the receiving groove 53 is located on a horizontally extending portion of the stepped structure.

In a specific implementation, the eccentric member 51 may be mounted on the sidewall of the mounting cavity 101 by a threaded connection. The mounting end of the eccentric part 51 penetrates through the thickness of the side wall of the mounting cavity 101, and a groove structure is arranged on the mounting end. The slot arrangement is located outside the mounting cavity 101 and is used to rotate the eccentric 51.

As shown in fig. 2, the positioning structure 52 is disposed on the eccentric member 51 and the side wall of the mounting cavity 101 for positioning the eccentric member 51. When the positioning structure 52 fixes the eccentric member 51, the eccentric member 51 can limit the front panel 3 at the predetermined position.

In this embodiment, the positioning structure 52 includes a positioning groove 522 and a positioning protrusion 521, which can be engaged with each other, wherein the positioning groove 522 is disposed on the eccentric member 51, the positioning protrusion 521 is disposed on an inner sidewall of the bottom case 1, and when the positioning protrusion 521 is locked in the positioning groove 522, the eccentric member 51 is positioned relative to the bottom case 1.

As shown in fig. 8, when the eccentric member 51 is positioned by the positioning structure 52, the eccentric member 51 protrudes from the inner sidewall surface of the mounting cavity 101, so that the front panel 3 can be limited to the predetermined position. As shown in fig. 4, 5 and 6, when the front panel 3 is not required to be limited, that is, when the eccentric member 51 is not required to be fixed, the large end of the eccentric member 51 can be entirely or partially accommodated in the accommodating groove 53 by rotation, and at this time, the eccentric member 51 does not affect the reciprocating motion of the front panel 3.

Switching device have multiple mode, for example flash mode, ordinary switch mode and normally off mode.

Referring to fig. 6 and 7, in the flash mode: the limiting mechanism 5 does not limit the front panel 3, and the reset mechanism 2 can enable the front panel 3 to be reset to a power-on state all the time. In this mode, the switching device also enables the maintenance circuit to be normally on.

Referring to fig. 4, in the normal switching mode: the reset mechanism 2 is switched to a self-locking state, the limiting mechanism 5 does not limit the front panel 3, when the front panel 3 is pressed, the elastic piece 21 cannot generate resilience force on the front panel 3, and then the movement of the front panel 3 is determined by external operation. That is, in this mode, the switching device can be brought into a power-on state or a power-off state by applying an operation to the front panel 3.

Referring to fig. 8, in the normally-off mode: the reset mechanism 2 is in a self-locking state, the limit mechanism 5 limits the front panel 3, and at the moment, the switch device is kept in a power-off state, even if the front panel 3 is controlled or contacted.
