[0074] The following embodiments are combined with the accompanying drawings to further illustrate the specific implementation of the dual power conversion switch of the present invention. The dual power conversion switch of the present invention is not limited to the description of the following embodiments.

[0075] like Figure 1-6As shown, the dual power transfer switch of this embodiment includes a switch mechanism 1 and a conversion mechanism 2. The switch mechanism 1 includes multiple phase pole units, each of which includes a movable contact and at least two static contacts, wherein the two static contacts are respectively connected to the normal power supply and the backup power supply. The movable contacts of the multiple phase pole units are arranged on a main shaft controlled by the conversion mechanism 2. The conversion mechanism 2 includes a housing and a drive mechanism, an electric mechanism, and a manual mechanism disposed in the housing. The electric mechanism and the manual mechanism drive the main shaft through the drive mechanism to drive the switch mechanism 1 to switch the normal power supply or the backup power supply. The main shaft drives the movable contacts of the multiple phase pole units to cooperate with their respective static contacts to conduct the normal power supply or the backup power supply, or to disconnect the normal power supply and the backup power supply at the same time. The electric mechanism is generally an electric motor or an electromagnetic mechanism. The manual mechanism includes a handle 4. One end of the handle 4 extends into the housing and is connected to the drive mechanism, and the other end is located outside the housing for manual operation. Each phase pole unit can be provided with one moving contact and two static contacts, or one moving contact and four static contacts, or two moving contacts and two static contacts, or two moving contacts and four static contacts, etc., to switch the normal power supply or the backup power supply. This is the prior art in this field. An improvement of this embodiment is that the hand-operated mechanism includes a handle 4 detachably connected to the drive mechanism, the housing of the conversion mechanism 2 is provided with a mounting slot 5 for storing the handle 4, a micro switch 6 and a trigger structure 7 are provided in the housing, the trigger structure 7 includes a drive portion 71 located in the mounting slot 5, and a trigger portion 72 for triggering the micro switch 6. When the handle 4 is inserted into the mounting slot 5, it can push the drive portion 71, so that the trigger portion 72 triggers the micro switch 6 to switch the output signal, which is used to feedback the installation status of the handle 4 and can indicate whether the handle 4 is removed or installed in place.

[0076] The dual power conversion switch of this embodiment does not need to be provided with a sliding cover for covering the handle 4, nor does it need to feedback whether the handle 4 is installed in place by triggering the micro switch 6 through the sliding cover. Instead, the handle 4 directly triggers the micro switch 6 to feedback whether the handle 4 is installed in place or removed, which has the characteristics of a small number of parts, a simple structure and low cost.

[0077] like Figure 3-4 As shown in the figure, the handle 4 is installed in place but the trigger structure 7 has not yet been activated. Although the figure shows that the driving part 71 has a part overlapping with the handle 4, in fact the two will not overlap. The handle 4 will push the driving part 71 to move downward. This is only used to illustrate the coordination relationship between the two.

[0078] like Figure 5-6As shown, the trigger structure 7 includes an elastic plate 73 for forming the mounting slot 5. The elastic plate 73 protrudes toward the inner direction of the mounting slot 5 to form the driving portion 71, and the elastic plate 73 protrudes toward the direction away from the mounting slot 5 to form the trigger portion 72. The handle 4 pushes the driving portion 71 to bend the elastic plate 73, and drives the trigger portion 72 to trigger the micro switch 6 to switch to outputting the first signal for feedback that the handle 4 is installed in place. After the handle 4 is removed, the elastic plate 73 resets and drives the trigger portion 72 away from the micro switch 6, causing the micro switch 6 to switch to outputting the second signal for feedback that the handle 4 is removed.

[0079] Specifically, such as Figure 7-8 As shown in FIG. 11 , the mounting slot 5 includes two first side plates 51 disposed opposite to each other, and two second side plates 52 connected between the two ends of the two first side plates 51 . The two second side plates 52 are disposed opposite to each other. Figure 5-6 As shown, two bottom plates are provided at the bottom of the mounting groove 5, and the elastic plate 73 is used to constitute one of the bottom plates. The two bottom plates are respectively a first bottom plate 53 and a second bottom plate 54, and the first bottom plate 53 and the second bottom plate 54 are respectively connected between the two first side plates 51, and the first bottom plate 53 and the second bottom plate 54 are spaced apart. A avoidance hole 55 is provided between the first bottom plate 53 and the second bottom plate 54, and the avoidance hole 55 is used to avoid the handle 4. After the handle 4 is removed from the mounting groove 5, it is inserted into the conversion mechanism 2 through the avoidance hole 55 and connected to the driving mechanism that drives the main shaft to rotate. The avoidance hole 55 corresponds to the handle hole of the driving mechanism in the shell, and the insertion portion 43 of the handle 4 is plugged into the handle hole. When the handle 4 rotates, the main shaft is driven to rotate by the driving mechanism. The mounting groove 5 can not only accommodate the handle 4, but also has a avoidance hole 55 for inserting the handle 4. After the handle 4 is disassembled and connected to the driving mechanism, it is placed horizontally in the mounting groove 5, and the avoidance hole 55 is blocked by the handle 4.

[0080] Further, such as Figure 3 、 Figure 5 As shown, the longitudinal cross-section of the avoidance hole 55 is arc-shaped and is used to avoid the turntable of the driving mechanism. The conversion mechanism 2 is provided with a driving mechanism, which includes a turntable, an elastic member, and an actuated member. The elastic member is connected between the turntable and the actuated member, and the actuated member is connected to the main shaft. The handle hole is provided on the outside of the turntable. The handle 4 is inserted into the handle hole to drive the turntable to rotate, so that the turntable drives the elastic member to store energy first, and then the elastic member releases energy to drive the actuated member to rotate the main shaft. The avoidance hole 55 is also used to avoid the turntable, so that the turntable is closely attached to the mounting slot 5, reducing the height of the conversion mechanism 2.

[0081] The length direction of the mounting groove 5 is set perpendicular to the axis of the main shaft, and the handle 4 is placed horizontally in the mounting groove 5. The switch mechanism 1 is provided with a main shaft connected to the driving mechanism. The length direction of the handle 4 when stored in the mounting groove 5 is set perpendicular to the main shaft. After the handle 4 is taken out of the mounting groove 5, it can be vertically passed through the avoidance hole 55 to be connected to the driving mechanism.

[0082] Furthermore, each of the two base plates includes a connected support plate 56 and a limit plate 57. The support plate 56 is arranged perpendicular to the direction in which the handle 4 is inserted into the mounting slot 5. The support plate 56 is used to limit the handle 4 when the handle 4 is installed in the mounting slot 5. The elastic plate 73 of the trigger structure 7 constitutes the support plate 56 of one base plate. The limit plates 57 of the two base plates are arranged at the end of each support plate 56 close to the other support plate 56. One end of the limit plates 57 of the two base plates is respectively connected to the respective support plates 56. The limit plates 57 of the two base plates are inclined away from the ends of the respective support plates 56. A clearance hole 55 is provided between the ends of the limit plates 57 of the base plates away from the respective support plates 56. The limit plates 57 are used to limit the rotation angle of the handle 4 when the handle 4 drives the main shaft to rotate. The turntable of the driving mechanism is rotatably arranged, and the turntable is at least partially located between the limit plates 57 of the two base plates. The uppermost position of the turntable is adjacent to the bottom of the mounting slot 5, so that the turntable is closely attached to the mounting slot 5, reducing the height of the conversion mechanism 2.

[0083] Further, if Figure 8 As shown, the sidewall of the mounting groove 5 is provided with a limiting structure 8, which is used to fix the handle 4 in the mounting groove 5. The limiting structure 8 can be a rib on the sidewall, which allows the handle 4 to have a slight interference fit with the mounting groove 5. Preferably, the limiting structure 8 is an elastic clamping arm integrally formed with the housing.

[0084] Furthermore, the trigger structure 7 is integrally formed with the housing. The support plate 56 formed by the elastic plate 73 is spaced apart from the two first side plates 51, and at least a portion of the limit plate 57 connected to the support plate 56 is connected to the two first side plates 51, so that the support plate 56 can bend and deform when the handle 4 pushes the driving part 71.

[0085] like Figure 7-8As shown, a plurality of mounting holes 58 are provided between the base plate and the two first side plates 51 on either side. Two mounting holes 58 are located on either side of one base plate having a support plate 56 formed of an elastic plate 73. The two mounting holes 58 are arranged correspondingly to the support plate 56 formed of the elastic plate 73, so that the support plate 56 formed of the elastic plate 73 is spaced apart from the two first side plates 51, allowing the support plates 56 to bend and deform when the handle 4 pushes the driving portion 71. The limiting plate 57 of the base plate is connected to the first side plates 51, and the limiting plate 57 is integrally formed with the first side plates 51 via the connecting portion 59 in the figure. The other base plate may also have mounting holes 58 on both sides, or may not have them. In this embodiment, both sides of the other base plate are provided with mounting holes 58 for cooperating with the limiting structure 8, so that the limiting structure 8 forms an elastic structure for limiting the handle 4. The trigger structure 7 of this embodiment is integrally formed with the housing, which is low in cost, high in reliability, and high in assembly efficiency. Of course, as other embodiments, the elastic plate 73 may be suspended in the middle of the support plate 56, or the elastic plate 73 may be rotatably installed to cooperate with the spring, which all fall within the protection scope of the present invention.

[0086] like Figure 7 As shown, the two first side panels 51 are respectively provided with a limit block 511 protruding toward the trigger structure 7. The limit blocks 511 on the two first side panels 51 are respectively inserted into the mounting holes 58 on both sides of the first bottom plate 53 to limit the bottom of the handle 4, that is, the limit block 511 serves as a part of the bottom of the mounting groove 5. When the handle 4 is horizontally or vertically in the mounting groove 5, the limit block 511 limits the installation position of the handle 4. The handle 4 is placed on the limit block 511 and the elastic plate 73 and compresses the elastic plate 73.

[0087] Furthermore, the first side panel 51 is provided with a side panel groove 512 for accommodating the limiting structure 8. The limiting structure 8 is integrally formed with the shell, and includes a second elastic plate 81 connected to the first side panel 51. The second elastic plate 81 is located in the side panel groove 512, and elasticity is formed on both sides by gaps. The second elastic plate 81 is provided with a limiting protrusion 82 protruding into the mounting groove 5, and a limiting groove 41 is provided on the side of the handle 4. The limiting protrusions 82 on the two first side panels 51 are respectively used to be clamped into the limiting grooves 41 for limiting cooperation.

[0088] Preferably, the cross section of the limiting protrusion 82 is semicircular, and the surface of the limiting protrusion 82 is curved, which can facilitate direct removal of the handle 4. Of course, the limiting protrusion 82 can also adopt a buckle structure, which belongs to the protection scope of the present utility model.

[0089] like Figure 1-6 As shown in FIG9 , the handle 4 includes a grip 42 and an inserting portion 43 provided at one end of the grip 42 , and a finger groove 44 is provided at the end of the grip 42 away from the inserting portion 43 Figure 2The insertion portion 43 is used to be plugged into the driving mechanism, and the two second side plates 52 of the mounting groove 5 are respectively limited with the end faces at both ends of the handle 42, wherein the second side plate 52 arranged on the side close to the insertion portion 43 is provided with a socket 521 for inserting the insertion portion 43, and the second side plate 52 arranged on the side away from the insertion portion 43 is provided with a removal groove 522 for inserting a finger. When removing the handle 4, the finger is inserted into the removal groove 522 and grips the finger groove 44 on the handle 42, and the handle 42 is pushed outward to rotate around the insertion portion 43 at a certain angle, and then the insertion portion 43 is pulled out of the socket 521, and the handle 4 can be taken out.

[0090] Furthermore, the handle 4 includes a grip 42 and an insertion portion 43 arranged at one end of the grip 42. The side of the mounting slot 5 is provided with a socket 521 for inserting the insertion portion 43. The driving portion 71 is arranged at the bottom of the mounting slot 5. When the insertion portion 43 is inserted into the socket 521, the grip 42 rotates toward the bottom of the mounting slot 5 and pushes the driving portion 71.

[0091] Preferably, the socket 521 is provided with a support surface 523, and the insertion portion 43 is arranged at an oblique angle to the support surface 523 when in contact with the support surface 523. The position where the insertion portion 43 contacts the support surface 523 serves as the rotation center of the handle 4, causing the handle 42 to rotate toward the bottom of the mounting slot 5, while simultaneously pushing the drive portion 71 through the side of the handle 42 at one end of which the insertion portion 43 is provided. By arranging the socket 521 on one side of the trigger structure 7 and installing the handle 4 into the mounting slot 5 by rotation, the drive portion 71 can be easily pushed using the principle of leverage to install the handle 4 into the mounting slot 5 for storage. This saves effort when pushing the drive portion 71, and solves the problem of not pushing it far enough to trigger the micro switch 6.

[0092] like Figure 3 、 10 As shown, the housing of the conversion mechanism 2 is provided with a bracket 9 for fixing the microswitch 6. The bracket 9 is located on the side of the trigger structure 7 away from the mounting slot 5. The bracket 9 is provided with two connecting plates 91, each of which has a screw hole 92 connected to a screw. The connecting plates 91 are connected to the housing of the conversion mechanism 2 by screws. The bracket 9 is provided with a limit column 93 and a limit platform 94. The microswitch 6 is provided with a limit hole 61 that is sleeved on the limit column 93. The limit platform 94 is used to limit the microswitch 6 away from the side of the trigger structure 7. Of course, the microswitch 6 can also be installed in other ways, such as directly on the housing, which falls within the scope of protection of the present utility model.

[0093] It should be noted that in the description of this utility model, the terms "upper," "lower," "left," "right," "inner," and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, or are conventionally placed directions or positional relationships during use.
