[0053] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0054] like Figure 1-Figure 7 As shown, the embodiment of the utility model provides a dual power conversion switch, which includes a base 1, a motor 2, a capacitor 3, a frame 4, a controller 5, two execution switches 6 and a housing 7. Among them, a first receiving groove 11 and a second receiving groove 12 that are interconnected are provided in the middle of the front of the base 1, and the first receiving groove 11 and the second receiving groove 12 are spaced apart along the width direction of the base 1 (i.e., the Y-axis direction shown in the figure); along the length direction of the base 1 (i.e., the X-axis direction shown in the figure), the two execution switches 6 are spaced apart on the base 1 and located on both sides of the first receiving groove 11, and the two ends of the frame 4 along the length direction of the base 1 are respectively fixed to the two execution switches 6; the upper end of the motor 2 along its axial direction (i.e., the Z-axis direction shown in the figure) is connected to the frame 4, and the lower end of the motor 2 along its axial direction is embedded in the first receiving groove 11, so that the motor 2 can be connected to the frame 4. The motor 2 is firmly fixed; the capacitor 3 includes a main body 31 and a convex bump 32 which are connected to each other, the main body 31 is arranged in the second accommodating groove 12, the convex bump 32 is arranged in the second accommodating groove 12 and extends toward the first accommodating groove 11, so that a part of the convex bump 32 extends into the first accommodating groove 11 and is located below the motor 2 along its axial direction; the controller 5 is arranged in the middle of the base 1, and along the width direction of the base 1, the controller 5 is located on the other side opposite to the second accommodating groove 12, and the controller 5 is used to control the motor 2; the housing 7 covers the two execution switches 6, and the housing 7 is used to provide protection for the frame 4, the motor 2 and the capacitor 3.

[0055] The dual power conversion switch is provided with a first accommodating groove 11 and a second accommodating groove 12 which are interconnected, so that the lower end of the motor 2 and the convex bump 32 of the capacitor 3 can be accommodated in the first accommodating groove 11 at the same time, and the convex bump 32 is located below the motor 2, thereby reducing the size of the space occupied by the motor 2 and the capacitor 3, and the capacitor 3 is directly installed in the second accommodating groove 12, so that the installation is convenient, firm, and the layout is beautiful.

[0056] In order to further improve the installation firmness of the motor 2, a support portion 111 is provided in the first accommodating groove 11 on the base 1. When the lower end of the motor 2 is embedded in the first accommodating groove 11, the lower end of the motor 2 along its axial direction can abut against the support portion 111, that is, the motor 2 is supported on the support portion 111, and the structure is more stable.

[0057] Specifically, refer to Figure 3As shown, there are three support parts 111, which are arranged at intervals on the groove wall of the first accommodating groove 11, and the three support parts 111 are evenly distributed, and the structural design is more reasonable. Of course, two, four or more support parts 111 can be arranged according to actual needs, and the number of support parts 111 is not limited here.

[0058] In order to further reduce the risk of interference between the bulge 32 and the motor 2, the depth of the second accommodating groove 12 along the axial direction of the motor 2 is greater than the depth of the first accommodating groove 11 along the axial direction of the motor 2. The second accommodating groove 12 includes a main groove 124 and an extension groove 125 that are interconnected, and the extension groove 125 extends into the first accommodating groove 11. The main body 31 is arranged in the main groove 124, and a part of the bulge 32 is arranged in the extension groove 125. This structure can increase the distance between the bulge 32 and the lower end of the motor 2. By increasing the depth of the second accommodating groove 12, the bulge 32 and the motor 2 are effectively prevented from interfering.

[0059] In order to improve the connection firmness of the capacitor 3 , a clamping structure is provided in the second receiving groove 12 on the base 1 , and the main body 31 is provided in the second receiving groove 12 and is clamped by the clamping structure.

[0060] Furthermore, if Figure 5-Figure 7 As shown, the clamping structure includes two clamping plates 121 and two clamping protrusions 122. Along the length direction of the base 1, the two clamping plates 121 are spaced apart in the main groove 124 of the second accommodating groove 12, and the two clamping protrusions 122 are respectively arranged on the opposite sides of the two clamping plates 121. When the main body 31 is arranged in the main groove 124, the two ends of the main body 31 along the length direction of the base 1 can be clamped with the two clamping protrusions 122 respectively, that is, the two ends of the main body 31 are respectively abutted against the lower end surfaces of the two clamping protrusions 122, so that the main body 31 is limited in the main groove 124. The capacitor 3 is firmly installed without screws, and the appearance is more beautiful.

[0061] Furthermore, along the length direction of the base 1, there is a gap 123 between the clamping plate 121 and the groove wall of the main groove 124 of the second accommodating groove 12. When the main body 31 is clamped into the main groove 124, the clamping plate 121 can be deformed toward the gap 123. When the main body 31 is clamped into the main groove 124 and is located at the lower end of the clamping protrusion 122, the clamping plate 121 returns to its original shape to make the clamping firm and the capacitor 3 is more convenient to install.

[0062] In order to make the main body 31 snap into the main groove 124 of the second accommodating groove 12 more smoothly, an inclined surface 1221 is provided at the upper end of the snap-in protrusion 122. When the main body 31 is snapped into the second accommodating groove 12, the inclined surfaces 1221 of the two snap-in protrusions 122 can provide guidance for the main body 31, making the operation more convenient.

[0063] Optionally, the base 1 is a plastic injection-molded part, and the plastic can be polyethylene, polypropylene or ABS. The use of plastic parts can effectively reduce the overall weight and make the structural design more reasonable.

[0064] Optionally, the upper end of the motor 2 along the axial direction thereof is connected to the frame 4 by screws, so that the motor 2 is more convenient to install.

[0065] In this embodiment, the two execution switches 6 are connected to the controller 5 through two sets of sampling lines respectively, along the length direction of the base 1, such as Figure 8 As shown, two groups of wire grooves 13 and two wire holes 14 are arranged at intervals on the back of the base 1. The two wire holes 14 pass through the two wire grooves 13 respectively. A wire outlet 15 is arranged on the side of the base 1. The two groups of sampling lines are respectively accommodated in the two wire grooves 13, and one end of each group of sampling lines passes through the corresponding wire outlet 15 to be connected with the corresponding execution switch 6, and the other end passes through the corresponding wire hole 14 to be connected with the controller 5. This structure allows the sampling lines to be arranged in the wire grooves 13, so that the layout of the sampling lines is beautiful.

Two groups of wire outlets 15 are arranged on the side of the base 1. Each group of wire outlets 15 includes multiple wire outlets 15 respectively connected with multiple wire branch grooves. In order to prevent the sampling line from escaping from the wire groove 13, a limiting boss 131 is arranged on the groove wall of each main wire groove. When the sampling line is arranged in the wire groove 13, it is located between the limiting boss 131 and the groove bottom of the wire groove 13 to improve stability.
