[0041] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of this utility model, not all embodiments.

[0042] Currently, many electrical appliances 600 use single-phase asynchronous motors as power sources, such as compressors. For starting single-phase asynchronous motors, electronic soft starters are generally used. In order to protect the internal soft starter control module 500, current electronic soft starters generally use a cover 200 to cover the soft starter control module 500. However, the existing technology requires separate installation and fixing of the cover 200 and the electronic soft starter and the electrical appliance 600, which is cumbersome, inconvenient to assemble, and cannot achieve quick assembly. Therefore, this utility model proposes a quick-install fixing structure for soft starting single-phase asynchronous motors.

[0043] like Figures 1 to 7 As shown, the quick-release fixing structure for soft starting of a single-phase asynchronous motor of this utility model includes: a mounting bracket 100, a cover 200, a fixing bracket 300, and a fixing pin 400.

[0044] like Figure 1 and Figure 5 As shown, the mounting bracket 100 of this utility model is provided with a mounting platform 110, which is used to install the starting electronic control module 500. In this embodiment, the mounting platform 110 is located on the top of the mounting bracket 100, and the cover 200 is placed on the upper side of the mounting platform 110 to form an electronic soft start device. The cover 200 is used to cover the starting electronic control module 500, wherein the starting electronic control module 500 includes a starting electronic control board and a starting capacitor, etc.

[0045] like Figure 7 As shown, the mounting bracket 300 is fixed to an external electrical appliance 600 with a single-phase asynchronous motor, wherein the electrical appliance 600 may be a compressor, etc. In this embodiment, the mounting bracket 300 is fixed to the outer casing of the compressor, specifically, the mounting bracket 300 is fixed to the left side of the outer casing of the compressor.

[0046] like Figure 1 As shown, in this embodiment, the mounting bracket 100 is provided with a first pin hole 120, the cover 200 is provided with a second pin hole 210, and the fixing frame 300 is provided with a third pin hole 310. After the cover 200 is placed on the mounting platform 110 and the mounting bracket 100 and the fixing frame 300 are assembled, the third pin hole 310, the second pin hole 210 and the first pin hole 120 are relatively coincident along a first direction. In this embodiment, the first direction is defined as the up-down direction, that is, the third pin hole 310, the second pin hole 210 and the first pin hole 120 are relatively coincident along the up-down direction. In some other embodiments, the third pin hole 310, the second pin hole 210 and the first pin hole 120 may coincide along other directions, such as the front-back direction.

[0047] The fixing pin 400 of this utility model is inserted into the third pin hole 310, the second pin hole 210 and the first pin hole 120 to lock the relative positions between the cover 200, the mounting bracket 100 and the fixing frame 300.

At the same time, the second pin hole 210 on the cover 200, the first pin hole 120 on the mounting bracket 100, and the third pin hole 310 on the fixing frame 300 are aligned vertically. Then, the fixing pin 400 is inserted between the third pin hole 310, the second pin hole 210, and the first pin hole 120 to lock the relative positions of the cover 200, the mounting bracket 100, and the fixing frame 300. This utility model achieves rapid assembly between the electronic soft starter and the electrical appliance 600 through the interlocking of the fixing pin 400, the cover 200, the fixing frame 300, and the mounting bracket 100, without the need for other tools, making assembly convenient.

[0049] To improve the stability of the assembly between the mounting bracket 100 and the fixing bracket 300, such as Figure 1 As shown, the mounting bracket 100 of this embodiment has a plug-in groove 130 on its side.

It can be understood that when the plug plate 320 is inserted into the plug slot 130, the second electrical plug 140 can be inserted into the first electrical plug 610 at the same time to realize the electrical connection between the start-up control module 500 and the electrical appliance 600.

[0051] like Figure 1 As shown, the mounting bracket 100 in this embodiment is also provided with a temperature sensor 150. The temperature sensor 150 is electrically connected to the start-up control module 500. The detection end of the temperature sensor 150 is in contact with the first electrical plug 610. The temperature sensor 150 is used to detect the operating temperature of the first electrical plug 610 and plays a role in temperature control protection.

[0052] Furthermore, such as Figure 1 As shown, the lower two sides of the fixing frame 300 in this embodiment are respectively provided with horizontally extending limiting plates 330. Specifically, in this embodiment, the front and rear sides of the fixing frame 300 are provided with limiting plates 330 extending to the left.

The front and rear positions between the fixing frame 300 and the mounting bracket 100 are locked by the two limiting plates 330, thereby improving the stability of the installation between the fixing frame 300 and the mounting bracket 100.

[0053] The clearance position 160 can be equipped with a clearance groove structure or a clearance hollow structure.

[0054] like Figures 4 to 6 As shown, regarding the connection and fixing method between the cover 200 and the mounting platform 110, the mounting platform 110 in this embodiment is provided with a plurality of second positioning parts 170, while the cover 200 is provided with a plurality of fourth positioning parts 220. The fourth positioning parts 220 and the second positioning parts 170 engage in a second direction. The first direction is perpendicular to the second direction. In this embodiment, the second direction is defined as from left to right. The relative positions of the cover 200 and the mounting platform 110 in the vertical direction are locked by the engagement of the second positioning parts 170 and the fourth positioning parts 220.

[0055] Specifically, the second positioning part 170 in this embodiment includes a second positioning block 171 disposed on the mounting platform 110, and the side of the second positioning block 171 is provided with a snap-fit ​​groove 172. The fourth positioning part 220 includes a snap-fit ​​plate 221 fixed to the inner side wall of the cover 200, and the snap-fit ​​groove 172 and the snap-fit ​​plate 221 engage in the left and right direction.

[0056] In this embodiment, the mounting platform 110 is provided with a plurality of first guide limiting parts 180, and the cover 200 is provided with a plurality of second guide limiting parts 230. The first guide limiting parts 180 and the second guide limiting parts 230 slide and engage one by one in the left and right direction to achieve guidance and pre-fixation for the installation of the cover 200.

[0057] In this embodiment, the cover 200 has a cover opening 240 facing the mounting platform 110, that is, the cover opening 240 is set downwards, and the right side of the cover 200 has a connection interface 250. The right side of the mounting platform 110 has a baffle 111, which is used to block the connection interface 250. In this embodiment, the cover 200 is installed from left to right.

[0058] The first guide limiting part 180 of this embodiment includes guide posts 181 fixed on the mounting platform 110. Specifically, in this embodiment, guide posts 181 are respectively provided at both ends of the edge of the mounting platform 110 away from the baffle 111. It can be understood that the two guide posts 181 are arranged at a distance from each other on the left side edge of the mounting platform 110. The second guide limiting part 230 includes a limiting groove 231 with the opening in the same direction as the interface 250 and a guide edge 232 extending in the left and right direction.

[0059] Among them, such as Figure 6 As shown, the inner side of the cover 200 away from the interface 250 is provided with two limiting slots 231, and the two opposite inner sides of the cover 200 are respectively set as guide edges 232.
