[0038] The first aspect of the present application discloses a power cord assembly 2000, which will be described in detail below by applying the power cord assembly 2000 to the motor 100. Figure 1 、 Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, in some embodiments of the present application, the power cord assembly 2000 includes an insulating protective shell 2100, a first connecting terminal 2300 and a power cord 2200, wherein the insulating protective shell 2100 has a accommodating cavity 2101 and a terminal groove 2102, the terminal groove 2102 is connected to the accommodating cavity 2101, one end of the power cord 2200 is connected to the first connecting terminal 2300, the first connecting terminal 2300 is arranged in the terminal groove 2102, the power cord 2200 passes through the accommodating cavity 2101 from the first connecting terminal 2300 and extends out of the insulating protective shell 2100, that is, the other end of the power cord 2200 is exposed outside the insulating protective shell 2100 (for connecting to the electronic control device), and the first connecting terminal 2300 is used to plug and connect with the pin 1210 of the motor 100. By setting the first connecting terminal 2300 to be connected to the pin 1210, power supply can be achieved through the power cord assembly 2000. On this basis, by setting the insulating protective shell 2100, the insulating protective shell 2100 can isolate the first connecting terminal 2300, ensure a certain electrical safety distance, and improve safety. In addition, by setting the insulating protective shell 2100, the direction of the power cord 2200 can be fixed, reducing the risk of friction between the power cord 2200 and the rotor 1400 of the motor 100.
[0039] Specifically, motor 100 includes a stator assembly 1200, a rotor 1400, and an end cap 1300. Rotor 1400 is rotatably mounted within stator assembly 1200. End cap 1300 is connected to one end of stator assembly 1200. One end of rotor shaft 1100 of rotor 1400 is rotatably supported on end cap 1300. End cap 1300 is generally made of metal to ensure structural strength. Stator assembly 1200 has windings, each terminated by a pin 1210. Power to the stator assembly 1200 is provided by connecting power cord assembly 2000 to pin 1210.
[0040] The power cord assembly 2000 includes an insulating protective housing 2100, a first connection terminal 2300, and a power cord 2200. The insulating protective housing 2100 is the primary structural component of the power cord assembly 2000, forming its skeleton. The insulating protective housing 2100 is made of an insulating material, such as plastic. The insulating protective housing 2100 can be integral or split. In this embodiment, the shape and structure of the insulating protective housing 2100 are not limited, as long as they accommodate the installation of the various components. The insulating protective shell 2100 is provided with a accommodating cavity 2101 and a terminal groove 2102. The accommodating cavity 2101 is located inside the insulating protective shell 2100 and is connected to the outside world (for the power cord 2200 to pass through). The terminal groove 2102 is connected to the accommodating cavity 2101 and the outside world. The first connecting terminal 2300 is arranged in the terminal groove 2102. The terminal groove 2102 can form a local wrapping protection for the first connecting terminal 2300. Since the terminal groove 2102 is connected to the outside world, the first connecting terminal 2300 can be plugged and connected to the pin 1210. One end of the power cord 2200 is connected to the first connecting terminal 2300, and the power cord 2200 is arranged along the accommodating cavity 2101 so that it can pass through the insulating protective shell 2100. In this way, the other end of the power cord 2200 is located outside the insulating protective shell 2100, which is convenient for connection with the electronic control device to realize power supply to the motor 100.
[0041] Generally speaking, the power cord 2200 and the first connecting terminal 2300 can be assembled together first, and then the power cord 2200 can be installed in the insulating protective shell 2100, so that the power cord assembly 2000 can constitute a separate module. During assembly, just operate the power cord assembly 2000 to move toward the pin 1210 and align the pin 1210, so as to achieve the first connecting terminal 2300 and the pin 1210. The connection, the assembly of the power cord assembly 2000 and the pin 1210 can be completed, which is convenient and quick, and does not require the circuit board to be soldered on the pin 1210 first as in the related art. The solution in this embodiment is conducive to reducing costs. Due to the presence of the insulating protective shell 2100, the insulating protective shell 2100 can isolate the first connecting terminal 2300. Since the first connecting terminal 2300 is plugged into the plug pin 1210, the insulating protective shell 2100 can also isolate the plug pin 1210. Generally speaking, the plug pin 1210 and the end cap 1300 are located at the same end of the stator assembly 1200. By providing the insulating protective shell 2100, the plug pin 1210 and the end cap 1300 can be isolated, thereby ensuring a certain electrical safety distance and improving safety. It can be understood that a portion of the power cord 2200 is arranged along the accommodating cavity 2101. This allows the portion of the power cord 2200 near the stator assembly 1200 to be constrained by the insulating protective shell 2100, thereby reducing the risk of friction between the power cord 2200 and the rotor 1400 and improving reliability.
[0042] Combine Figure 1 and Figure 6 As shown, in some embodiments of the present application, the number of the first connection terminals 2300 includes three, the pins 1210 correspond one-to-one to the first connection terminals 2300, the power cords 2200 correspond one-to-one to the first connection terminals 2300, and the terminal slots 2102 correspond one-to-one to the first connection terminals 2300.
[0043] Specifically, the motor 100 is a three-phase motor 100 and includes three pins 1210. Therefore, the power cord assembly 2000 also includes three first connection terminals 2300 and three power cords 2200. The three first connection terminals 2300 correspond one-to-one with the three pins 1210, and the three power cords 2200 correspond one-to-one with the three first connection terminals 2300. The insulating protective shell 2100 has three terminal slots 2102, and the three terminal slots 2102 correspond one-to-one with the three first connection terminals 2300. Because the power cord assembly 2000 can be formed into an independent module, after the three first connection terminals 2300 are respectively installed in the three terminal slots 2102, when the power cord assembly 2000 is connected to the pins 1210, the operator can operate the power cord assembly 2000 to move toward the pins so that the three first connection terminals 2300 and the three pins 1210 are plugged in together, thereby improving production efficiency and eliminating the need for the operator to perform the plugging process three times, thereby avoiding plugging errors.
[0044] Further, combined with Figure 6 As shown, in some embodiments of the present application, the power cord assembly 2000 also includes a second connection terminal 2400, and the other ends of the three power cords 2200 are connected to the second connection terminal 2400, thereby being connected to the electronic control device through the second connection terminal 2400, thereby realizing power supply to the motor 100.
[0045] Specifically, one end of the power cord 2200 is connected to the first connection terminal 2300, and the other end of the power cord 2200 is exposed outside the insulating protective shell 2100. If the other ends of the three power cords 2200 are respectively provided with connection terminals to connect to the electronic control device, the operation is slightly troublesome and connection errors are prone to occur. For this reason, in this embodiment, by setting a second connection terminal 2400, the other ends of the three power cords 2200 all need to be connected to the second connection terminal 2400, and then can be plugged into the electronic control device through the second connection terminal 2400, thereby improving the connection convenience between the power cord assembly 2000 and the electronic control device, thereby realizing power supply to the motor 100.
[0046] Combine Figure 1 、 Figure 2 and Figure 5 and Figure 6 As shown, in some embodiments of the present application, the insulating protective shell 2100 and the three first connection terminals 2300 are arranged in a similar manner, which is more conducive to adapting to the environment in which the three pins 1210 are located and maximizing the use of space.
[0047] Specifically, the stator assembly 1200 of the motor 100 is generally cylindrical in shape. Therefore, the three pins 1210 are generally designed to be arranged in an arc shape, that is, the line connecting the three pins 1210 forms a roughly arc shape. To ensure that the three first connecting terminals 2300 correspond to the three pins 1210, the three first connecting terminals 2300 also need to be arranged in an arc shape after being secured to the three terminal slots 2102. Since one end of the stator assembly 1200 not only has the pins 1210 but also connects to the end cap 1300, and given that the three first connecting terminals 2300 are also arranged in an arc shape, the insulating protective housing 2100 is designed to be roughly arc-shaped. This design emulates the shape of the three first connecting terminals 2300. This effectively utilizes space, avoids interference between the insulating protective housing 2100 and other structures, and ensures protection for the first connecting terminals 2300 and the power cord 2200.
[0048] Combine Figure 6 and Figure 7 As shown, in some embodiments of the present application, the insulating protective shell 2100 includes a base 2120 and a cover 2110, the cover 2110 covers the base 2120 to connect with each other, and the cover 2110 and the base 2120 also enclose a accommodating cavity 2101, and the terminal slot 2102 is set on the base 2120. The setting of the base 2120 and the cover 2110 facilitates the manufacture of the insulating protective shell 2100, and also facilitates the installation of the power cord 2200 and the first connection terminal 2300 on the insulating protective shell 2100.
[0049] Specifically, as mentioned above, the insulating protective shell 2100 can be integral or split. For the former, if the insulating protective shell 2100 is an integral structure, it will be much more difficult to install the first connecting terminal 2300 into the terminal slot 2102 and to pass the power cord 2200 out of the accommodating cavity 2101. In this embodiment, the insulating protective shell 2100 includes a base 2120 and a cover 2110. The base 2120 is provided with the above-mentioned terminal slot 2102. Before the base 2120 and the cover 2110 are assembled with each other, the first connecting terminal 2300 can be inserted into the terminal slot 2102 first, and the power cord 2200 can be arranged along the side of the base 2120 toward the cover 2110, and then the cover 2110 is covered on the base 2120 and connected to each other. A accommodating cavity 2101 is formed between the base 2120 and the cover 2110, so that the power cord 2200 is in a state of passing through the accommodating cavity 2101, which facilitates the assembly of the power cord assembly 2000.
[0050] Further, combined with Figure 6As shown, in some embodiments of the present application, at least one of the base 2120 and the cover 2110 is provided with a wire hook 2121, and the wire hook 2121 is used to hook the power cord 2200, thereby fixing the power cord 2200. The wire hook 2121 can be provided on the base 2120, the cover 2110, or both the base 2120 and the cover 2110. In this embodiment, the base 2120 is provided with a wire hook 2121 as an example for explanation. As mentioned above, when assembling the power cord assembly 2000, the first connection terminal 2300 can be first installed in the terminal slot 2102, and then the power cord 2200 can be arranged along the base 2120, and finally the cover 2110 can be closed. In order to prevent the position of the power cord 2200 from shifting when the cover 2110 is covered on the base 2120, a wire hook 2121 is provided on the base 2120. When the power cord 2200 is arranged along the base 2120, it can be clipped into the wire hook 2121 and thus hooked by the wire hook 2121, thereby limiting the displacement of the power cord 2200 relative to the base 2120. There are many types of wire hooks 2121, as long as they can limit the power cord 2200. For example, the wire hook 2121 is in the shape of a "7". The wire hooks 2121 may include multiple (two or more) wire hooks 2121, which are arranged along the layout of the power cord 2200 to more effectively limit the position of the power cord 2200. The wire hooks 2121 may also be designed to be arranged in pairs, with the paired wire hooks 2121 located on both sides of the power cord 2200. In addition, when the cover 2110 covers the base 2120, it can also effectively restrain the power cord 2200 from shaking relative to the insulating protective shell 2100.
[0051] Combine Figure 6 and Figure 7 As shown, in some embodiments of the present application, the base 2120 and the cover 2110 jointly clamp the power cord 2200, which can also prevent the power cord 2200 from shaking relative to the insulating protective shell 2100. Specifically, when the cover 2110 and the base 2120 are connected to each other, the corresponding positions on the cover 2110 and the corresponding positions on the base 2120 jointly clamp the portion of the power cord 2200 located between the cover 2110 and the base 2120, thereby limiting the shaking of the power cord 2200 relative to the insulating protective shell 2100, preventing relative wear between the power cord 2200 and the insulating protective shell 2100, and effectively achieving the restraint and fixation of the power cord 2200.
[0052] In some embodiments of the present application, the base 2120 and the cover 2110 are designed to be detachably connected. The so-called detachable connection means that they can be fixed together and can be detached when needed. The detachable connection facilitates the assembly of the base 2120 and the cover 2110 and also facilitates subsequent disassembly and maintenance. It is understood that the detachable connection methods include various methods such as threaded connection and snap connection.
[0053] In order to improve the convenience of the detachable connection between the base 2120 and the cover 2110, the detachable connection between the base 2120 and the cover 2110 is realized by a snap connection, so that the base 2120 and the cover 2110 can be assembled and disassembled without the use of external tools.
[0054] Specifically, combined Figure 4 and Figure 6 As shown, one of the base 2120 and the cover 2110 is provided with an undercut 2111, and the other one of the base 2120 and the cover 2110 is provided with a barb 2122. The base 2120 and the cover 2110 are detachably connected by the buckle 2111 and the barb 2122. During assembly, the assembly can be achieved by simply buckling the undercut 2111 and the barb 2122 together. During disassembly, force is applied to the undercut 2111 to deform the undercut 2111 and separate it from the barb 2122, thereby achieving disassembly. For example, the base 2120 is provided with a barb 2122, and the cover 2110 is provided with an undercut 2111; or the base 2120 is provided with an undercut 2111, and the cover 2110 is provided with a barb 2122; or the base 2120 is provided with an undercut 2111 and a barb 2122, and the cover 2110 is also provided with a barb 2122 and an undercut 2111, the undercut 2111 of the base 2120 corresponds to the barb 2122 of the cover 2110, and the barb 2122 of the base 2120 corresponds to the undercut 2111 of the cover 2110.
[0055] Combine Figure 7 As shown, in some embodiments of the present application, one of the base 2120 and the cover plate 2110 is provided with a guide rib 2112 along the circumferential direction, and the guide rib 2112 is used to abut against the inner wall of the other one of the base 2120 and the cover plate 2110, thereby improving the accuracy of the cover plate 2110 covering the base 2120 and preventing the cover plate 2110 and the base 2120 from offsetting each other when assembled.
[0056] Specifically, taking the guide ribs 2112 provided on the cover 2110 as an example, the guide ribs 2112 provided on the base 2120 are similar and will not be described in detail. The guide ribs 2112 are provided on the side of the cover 2110 facing the base 2120 and are provided near the edge of the cover 2110. The guide ribs 2112 extend along the circumference of the cover 2110. The guide ribs 2112 can be a complete uninterrupted circle or can be arranged intermittently along the circumference. When the cover 2110 is covered on the base 2120, the guide ribs 2112 are embedded in the base 2120 and abut against the inner wall of the base 2120. This limits the relative position of the cover 2110 relative to the base 2120, avoids the cover 2110 from being offset relative to the base 2120 during the assembly of the power cord assembly 2000, and is more conducive to assembly.
[0057] Combine Figure 1 and Figure 2 As shown, in some embodiments of the present application, the insulating protective shell 2100 can also be connected and fixed to the end cover 1300 of the motor 100. When the first connection terminal 2300 is plugged into the pin 1210, the installation and fixation of the power cord assembly 2000 can be completed, and a fixed point is formed between the first connection terminal 2300 and the pin 1210. In order to further improve the installation stability of the power cord assembly 2000, the insulating protective shell 2100 is connected and fixed to the end cover 1300, thereby greatly improving the installation stability of the power cord assembly 2000. It is understandable that there are many ways to connect and fix the insulating protective shell 2100 and the end cover 1300, as long as a constraint is generated between the end cover 1300 and the insulating protective shell 2100.
[0058] For example, combined with Figure 3 As shown, the insulating protective shell 2100 is provided with a fixing hook 2123. When operating the power cord assembly 2000 to plug and connect the first connecting terminal 2300 with the pin 1210, the fixing hook 2123 slides under the fixing platform 1310 of the end cover 1300. The fixing platform 1310 limits the fixing hook 2123, thereby limiting the power cord assembly 2000, thereby further improving the installation stability of the power cord assembly 2000 and preventing the power cord assembly 2000 from loosening.
[0059] Specifically, the end cover 1300 and the pin 1210 are a certain distance apart along the axial direction of the motor 100. When installing the power cord assembly 2000, the staff controls the power cord assembly 2000 along the approximately axial direction so that the first connecting terminal 2300 is plugged into the pin 1210. During this process, the fixing hook 2123 first abuts the fixing platform 1310, and then the fixing hook 2123 and / or the fixing platform 1310 are deformed. On the premise that the first connecting terminal 2300 and the pin 1210 are plugged into place, the fixing hook 2123 and / or the fixing platform 1310 are reset. At this time, the fixing hook 2123 is located below the fixing platform 1310. The below here is the inner side of the fixing platform 1310. In this way, the fixing platform 1310 presses against the fixing hook 2123 to prevent the power cord assembly 2000 from moving in the opposite direction and falling out.
[0060] Furthermore, in some embodiments of the present application, the first connecting terminal 2300 is a self-locking terminal, that is, after the first connecting terminal 2300 is connected to the pin 1210, when not manually pulled out, the first connecting terminal 2300 and the pin 1210 have a high connection stability and are not easy to separate, thereby avoiding poor contact. In conjunction with the fixing hook 2123 and the fixing platform 1310, the installation stability of the power cord assembly 2000 is greatly improved.
