[0011] The wire harness fixing unit includes:

[0012] At least two first fixing parts are defined as the side of the box body facing the tube assembly as the front side, and the front side has a protruding first fixing part; the first fixing part has a first fixing surface; the first fixing surface and the wire harness outlet are located at different positions of the box body in the thickness direction, and the first fixing surface of at least two first fixing parts is located at different positions of the box body in the thickness direction.

[0013] A first restraint member is installed on a first fixed surface. The first restraint member is used to restrain the first wire harness when the first wire harness is led to the first fixed surface.

[0014] The above technical solution has the following advantages or beneficial effects: the first wire harness can be fixed to the first fixing part by the first binding member to constrain the first wire harness to the front of the box body; at least two first fixing parts are provided, and the first fixing surfaces of the at least two first fixing parts are located at different positions of the box body in the thickness direction. When the first wire harness is fixed to the first fixing surfaces on different first fixing parts, the first wire harness can be bent into a certain arc and attached to the front of the box body, so that the wiring of the first wire harness outside the control box is not easy to become messy, which can improve the stability of the first wire harness. The first wire harness is not easy to shake, so that the first wire harness is not easy to touch the cylinder assembly, thereby reducing or avoiding fire caused by friction between the first wire harness and the cylinder assembly.

[0015] In some embodiments of this application, the surface on the box that intersects with the front is defined as the side surface. The box has two side surfaces, including a first side surface and a second side surface. The first side surface is provided with a wire harness outlet.

[0016] At least two first fixing parts are spaced apart on the front side near the wire harness outlet.

[0017] The above technical solution has the following advantages or beneficial effects: a wire harness outlet is provided on the first side. After the first wire harness passes through the wire harness outlet, it runs along the front of the box. The front of the box can support the first wire harness, making the first wire harness less prone to shaking. At least two first fixing parts are spaced apart in the area of ​​the front near the wire harness outlet. The two adjacent first fixing parts are separated by a certain distance, which can fix different positions of the first wire harness and allow the at least two first fixing parts to constrain a certain length of the first wire harness.

[0114] It should be noted that a wire harness outlet 422 is provided on the first side. After the first wire harness passes through the wire harness outlet 422, it runs along the front of the box. The front of the box can support the first wire harness, making it less prone to shaking. At least two first fixing parts 423 are spaced apart in the area near the wire harness outlet 422 on the front. The two adjacent first fixing parts 423 are spaced a certain distance apart, which can fix the first wire harness at different positions and allow the at least two first fixing parts 423 to constrain a certain length of wire harness.

[0115] Please see Figures 7-8 and Figure 10In some embodiments of this application, at least two first fixing parts 423 include a first sub-fixing part and a second sub-fixing part. The first sub-fixing part is located on the front side adjacent to the wire harness outlet 422. The first sub-fixing part has a second sub-fixing part on the side facing the second side. Along the projection direction from the front to the inner wall of the housing 100, the first fixing surface of the second sub-fixing part is higher than the first fixing surface of the first sub-fixing part.

[0116] It should be noted that after the first wire harness passes through the wire harness outlet 422, it undergoes a preliminary bend. The bent first wire harness is then fixed to the first sub-fixing part and the second sub-fixing part, and then led to other electrical components that need to be electrically connected. The distance between the wire harness outlet 422 and the cylinder assembly is greater than the distance between the first sub-fixing part and the cylinder assembly, and the distance between the first sub-fixing part and the cylinder assembly is greater than the distance between the second sub-fixing part and the cylinder assembly. This allows the first wire harness outside the control box to be in a naturally elongated state, and the first wire harness can form a certain arc to adhere to the front of the box, making the fixation of the first wire harness more secure and the first wire harness less prone to shaking.

[0117] Please see Figure 8 and Figure 10 In some embodiments of this application, the first sub-fixing part and the second sub-fixing part have the same dimensions in the thickness direction of the box body, the front side is a concave-convex surface, the second sub-fixing part is provided on the protruding part of the concave-convex surface, and the first sub-fixing part is provided on the recessed part of the concave-convex surface.

[0118] With this configuration, when the dimensions of the first and second sub-fixing parts are the same in the thickness direction of the box, it is easy to manufacture. When the second and first sub-fixing parts are located on the raised and recessed parts of the concave and convex surfaces, respectively, the first and second sub-fixing parts are located at different heights. The second and first sub-fixing parts can be set to conform to the external shape of the box, which is less likely to affect the heat dissipation of the box. The first wire harness can form a certain arc and stick to the front of the box and be in a natural elongated state. The first wire harness is more firmly fixed and less prone to shaking.

[0119] In some embodiments of this application, the front side is a plane, and the dimension of the first sub-fixing part in the thickness direction of the box body is smaller than the dimension of the second sub-fixing part in the thickness direction of the box body.

[0120] With this configuration, when the front is a flat surface, the dimension of the first sub-fixing part in the thickness direction of the box can be set to be smaller than the dimension of the second sub-fixing part in the thickness direction of the box, so that the first sub-fixing part and the second sub-fixing part are located at different heights, allowing the first wire harness to form a certain arc and adhere to the front of the box in a naturally elongated state, making the fixation of the first wire harness more secure and less prone to shaking.

[0121] In some embodiments of this application, the wiring harness further includes a second wiring harness having a connector. One of the controllers has a plug hole and a clearance opening 425 on its front side. The connector is disposed within the clearance opening 425 and plugged into the plug hole. The second wiring harness may be a power cord.

[0122] Please see Figures 7-8 In some embodiments of this application, the wire harness fixing unit may include a second fixing part 424. The second fixing part 424 is disposed on the side of the housing, for example, a second side has a protruding second fixing part 424. The second fixing part 424 has a second fixing surface facing the cylindrical assembly. Specifically, the second fixing surface is provided with a plurality of fixing positions, and fixing holes can be provided on each of the plurality of fixing positions, wherein the second fixing part 424 near the clearance opening 425 is used to constrain the second wire harness.

[0123] In some embodiments of this application, the wire harness fixing unit may include a second restraining member. The second restraining member is mounted on the second fixing part 424 and is used to restrain the second wire harness when it is led to the second fixing surface. Specifically, the second restraining member can pass through a fixing hole to bind the second wire harness to the fixing position.

[0124] The second wire harness can be fixed to the second fixing part 424 by the second binding member to constrain the second wire harness to the side of the box, which can improve the stability of the second wire harness and prevent the second wire harness from shaking.

[0125] In some embodiments of this application, the first and second binding members can be flexible structures in the form of strips or ropes, which can be knotted to form a ring-shaped space to achieve the function of binding the wire bundle.

[0126] In some embodiments of this application, the first fixing part 423 and the second fixing part 424 can fix other wire harnesses passing through the control box 400, reducing or avoiding wire harness tangling.

[0127] Please see Figure 3 and Figure 6 In some embodiments of this application, the control box 400 may include a connection component. The connection component can be used to connect the control box 400 to the housing 100.

[0128] In some embodiments of this application, in the thickness direction of the rear shell 110, that is, in the front-rear direction of the housing 100, a connecting component is disposed between the housing and the rear shell 110, and the housing is connected to the rear shell 110 through the connecting component.

[0129] In some embodiments of this application, the housing may include a base 410 and a cover 420. The base 410 may be used to fix the control device. The cover 420 may be used to cover the control device together with the base 410.

[0130] Please see Figure 3 and Figure 6 In some embodiments of this application, the base 410 can be fixed to the rear shell 110 by a connecting component. The connecting component can be fixed to the rear shell 110 to achieve the fixation of the base 410 and the rear shell 110.

[0131] In some embodiments of this application, the connecting component may be fixed to the base 410. The connecting component may move together with the base 410.

[0132] Please see Figure 6 and Figure 8 In some embodiments of this application, the base 410 and the cover plate 420 together form a receiving cavity, which is used to house at least the control device.

[0133] In some embodiments of this application, both the base 410 and the cover plate 420 may be provided with grooves. The grooves of the base 410 and the cover plate 420 may be arranged opposite to each other, so that the grooves of the base 410 and the cover plate 420 can together form a receiving cavity.

[0134] In some embodiments of this application, the shape of the groove in the base 410 can be adapted to the shape of the controller, which can improve the installation stability of the controller.

[0135] In some embodiments of this application, the groove shape of the cover plate 420 can be adapted to the shape of the controller, which can improve the installation firmness of the controller.

[0136] Please see Figures 8-11 In some embodiments of this application, the cover plate 420 is provided with a snap-fit ​​groove 421. The snap-fit ​​groove 421 can extend outward from the inner wall of the cover plate 420.

[0137] In some embodiments of this application, the base 410 is provided with a snap-fit ​​portion 413. The snap-fit ​​portion 413 may be provided on the side wall of the base 410 perpendicular to the housing 100. By snapping the snap-fit ​​portion 413 into the snap-fit ​​groove 421, the base 410 and the cover plate 420 can be fixedly connected.

[0138] Please refer to 11. In some embodiments of this application, the base 410 may include a bottom surface and four sides. One or more snap-fit ​​portions 413 may be provided on the four sides.

[0139] Please see Figures 8-9 In some embodiments of this application, the snap-fit ​​grooves 421 on the cover plate 420 can correspond one-to-one with the snap-fit ​​portions 413 on the base 410. The snap-fit ​​portions 413 on the four sides simultaneously snap into the snap-fit ​​grooves 421 on the cover plate 420, which can improve the connection stability between the cover plate 420 and the base 410.

[0140] In some embodiments of this application, a snap-fit ​​portion 413 may include a pair of snap-fit ​​tabs. The pair of snap-fit ​​tabs can reduce the wobbling of the snap-fit ​​portion 413 within the snap-fit ​​groove 421 and improve the connection stability between the cover plate 420 and the base 410.

[0141] In some embodiments of this application, the snap-fit ​​slot 421 can be a rectangular hole, a square hole, or a trapezoidal hole, etc. Pairs of snap-fit ​​pieces can be inserted into rectangular holes, square holes, or trapezoidal holes, etc., to achieve the connection between the cover plate 420 and the base 410.

[0142] In some embodiments of this application, the size of the end of the snap-fit ​​tab near the cover plate 420 can be smaller than the size of the end near the rear housing 110. This allows a guide structure to be formed on the snap-fit ​​tab, facilitating insertion of the snap-fit ​​tab into the snap-fit ​​slot 421.

[0143] In some embodiments of this application, the cover plate 420 may be provided with a flange, and the snap-fit ​​groove 421 is provided on the flange. The flange of the cover plate 420 may be an elastic element. During the process of inserting the snap-fit ​​part 413 into the snap-fit ​​groove 421, the deformation of the flange of the cover plate 420 facilitates the insertion of the snap-fit ​​part 413 into the snap-fit ​​groove 421.

[0144] In some embodiments of this application, the depth of the snap-fit ​​groove 421 may be less than the thickness of the flange of the cover plate 420. The height of the snap-fit ​​portion 413 may be equal to the depth of the snap-fit ​​groove 421. After the snap-fit ​​portion 413 is inserted into the snap-fit ​​groove 421, the end of the snap-fit ​​portion 413 may abut against the bottom surface of the groove 421.

[0145] Please see Figures 8-11 In some embodiments of this application, the snap-fit ​​groove 421 can penetrate the cover plate 420. When the cover plate 420 is connected to the base 410, the snap-fit ​​portion 413 passes through the snap-fit ​​groove 421. The height of the snap-fit ​​portion 413 can be greater than or equal to the depth of the snap-fit ​​groove 421. After the snap-fit ​​portion 413 is inserted into the snap-fit ​​groove 421, the end of the snap-fit ​​portion 413 can pass through the snap-fit ​​groove 421.

[0146] Please see Figure 9 and Figure 11 In some embodiments of this application, the connecting component includes a limiting member 411. The limiting member 411 can be installed on the rear cover 110 to enable the connection between the connecting component and the rear cover 110.

[0147] In some embodiments of this application, the limiting member 411 may be disposed on the surface of the box body facing the rear shell 110, so that the distance between the limiting member 411 and the rear shell 110 is less than the distance between the box body and the rear shell 110.

[0148] In some embodiments of this application, the limiting member 411 can be inserted into the mounting opening 111 and engaged with the rear shell 110. By sliding the limiting member 411 downward after it is inserted into the mounting opening 111, the limiting member 411 can be connected to the rear shell 110, thereby achieving a pre-connection between the box and the rear shell 110.

[0149] By pre-connecting the box body to the rear shell 110, the control box 400 can be suspended on the rear shell 110, eliminating the need to hold the control box 400 in your hand at all times. This reduces the labor intensity of installing the control box 400 and makes the installation of the control box 400 more convenient.

[0150] Please see Figure 7 , Figure 9 and Figure 11 In some embodiments of this application, the number of limiting members 411 is two or more, and the two or more limiting members 411 are spaced apart along the periphery of the box. At least one of the limiting members 411 can be located at the bottom end of the box, which facilitates the limiting member 411 to pass through the mounting opening 111, making the installation process of the limiting member 411 less susceptible to interference from other components.

[0151] Please see Figure 9 and Figure 11 In some embodiments of this application, the limiting member 411 may include a connecting portion 4111. The connecting portion 4111 is connected to the housing and passes through the mounting opening 111. The end of the connecting portion 4111 near the base 410 can be fixedly connected to the base 410. The connecting portion 4111 can be fixed to the base 410 by integral molding or plug-in connection.

[0152] Please see Figure 9 and Figure 11 In some embodiments of this application, the limiting member 411 may include a bent portion 4112. The bent portion 4112 may include a first end and a second end. The first end of the bent portion 4112 may be connected to the connecting portion 4111, and the second end of the bent portion 4112 may extend downward. One end of the connecting portion 4111 is connected to the housing, and the other end is connected to the bent portion 4112.

[0153] In some embodiments of this application, the bent portion 4112 is fixed relative to the box body via the connecting portion 4111. The bent portion 4112 can be fixedly connected to the connecting portion 4111, and the connecting portion 4111 can be fixedly connected to the base 410, thereby achieving relative fixation between the bent portion 4112 and the box body.

[0154] Please see Figures 4-5 and Figure 9In some embodiments of this application, the connecting part 4111 can be inserted into the mounting opening 111, and the bent part 4112 can be located on the surface of the rear shell 110 away from the box body and snapped into the rear shell 110. The bent part 4112 abuts against the surface of the rear shell 110 away from the box body, which makes it difficult for the limiting member 411 to detach from the rear shell 110.

[0155] In some embodiments of this application, when the bent portion 4112 abuts against the rear shell 110, at least one side of the connecting portion 4111 abuts against the inner wall of the mounting opening 111. One end of the bent portion 4112, away from the connecting portion 4111, extends towards the bottom edge of the rear shell 110 and abuts against it. The inner wall of the mounting opening 111 can support the bottom end of the connecting portion 4111. By the abutment of the connecting portion 4111 against the inner wall of the mounting opening 111 and the abutment of the bent portion 4112 against the surface of the rear shell 110, the limiting member 411 is less likely to detach from the rear shell 110.

[0156] Please see Figures 4-5 In some embodiments of this application, the control box 400 further includes a fastener 415. The fastener 415 passes through one of the box body and the rear shell 110, and the fastener 415 is screwed into the other of the box body and the rear shell 110 to connect the box body and the rear shell 110.

[0157] Please see Figures 3-6 In some embodiments of this application, the rear housing 110 has a raised region that protrudes toward the side opposite to the cylinder assembly. Along the depth direction of the housing, that is, along the front-rear direction of the housing, the cylinder assembly is opposite to the raised region.

[0158] In some embodiments of this application, the housing also has a fastener 412. The control box 400 is connected to the rear shell 110 via the fastener 412. The fastener 412 is disposed on the surface of the housing facing the rear shell 110. After the housing and the rear shell 110 are pre-connected, the surface of the fastener 412 facing the rear shell 110 abuts against the rear shell 110.

[0159] Specifically, in the thickness direction of the rear shell 110, the control box 400 is fixedly connected to the rear shell 110 via a fastener 412. After the box body and the rear shell 110 are pre-connected by the limiting member 411 passing through the mounting port 111, the control box 400 is fixedly connected to the rear shell 110 via the fastener.

[0160] Please see Figures 3-6 In some embodiments of this application, the fastener 412 is located at a position opposite to the protruding area of ​​the box body, and the end of the fastener 412 away from the box body abuts against the rear shell 110. This facilitates the connection between the fastener 412 and the rear shell 110.

[0161] In some embodiments of this application, the fastener 412 is detachably connected to the rear housing 110. The end of the fastener 412 facing the rear housing 110 has a threaded hole, and the fastener 415 is screwed into the threaded hole, which facilitates the fastener 412 to be removed from the rear housing 110 for maintenance.

[0162] Please see Figures 4-5 and Figures 9-11 In some embodiments of this application, the fastener 412 can be a connecting post. The connecting post can be fixedly connected to the base 410, which can improve the connection reliability between the connecting post and the base 410.

[0163] In some embodiments of this application, the connecting column can be fixedly connected to the base 410 by integral molding or snap-fit, so as to improve the connection reliability between the connecting column and the base 410.

[0164] In some embodiments of this application, the rear housing 110 has a through hole at the position of the corresponding fastener 415, and the fastener 415 passes through the through hole and is detachably connected to the connecting post. The fastener 415 can be a bolt that mates with the connecting post. The connecting post can be fixed to the rear housing 110 by bolts.

[0165] Specifically, bolts are inserted through the rear housing 110 and threadedly connected to the connecting column. The threaded connection between the bolts and the connecting column allows for a fixed connection between the connecting column and the rear housing 110.

[0166] Please see Figures 9-11 In some embodiments of this application, one or more connecting posts may be provided. The number of connecting posts can correspond one-to-one with the number of bolts. Multiple connecting posts can be arranged to avoid protrusions or holes, depending on the shape of the rear shell 110.

[0167] In some embodiments of this application, the base 410 can be fixed to the rear shell 110 by the limiting member 411 and the fixing member 412.

[0168] In some embodiments of this application, at least one of the plurality of limiting members 411 is located below the fixing member 412. The limiting member 411 being located below the fixing member 412 can reduce the interference of the fixing member 412 on the limiting member 411, which is beneficial for the limiting member 411 to be installed in the mounting port 111.

[0169] Please see Figures 9-11 In some embodiments of this application, the surface of the housing facing the rear shell 110 is spaced apart from the rear shell 110, and the connecting post is disposed within the space. The space between the housing and the rear shell 110 can accommodate the connecting post, which facilitates the contact between the surface of the connecting post facing away from the housing and the rear shell 110.

[0170] Please see Figure 9 and Figure 11In some embodiments of this application, the control box 400 further includes a wiring structure 414. The base 410 and the cover plate 420 can constitute a box body. The wiring structure 414 is disposed between the box body and the rear shell 110; specifically, the wiring structure 414 is disposed on the side of the box body facing the rear shell 110. The wiring structure 414 can constrain the third wiring harness passing through the control box 400, improving the stability of the third wiring harness and reducing its swaying.

[0171] In some embodiments of this application, a wiring structure 414 and a connecting post are provided in the gap between the housing and the rear shell 110, which can make full use of the space in the gap.

[0172] In some embodiments of this application, the distance between the wiring structure 414 and the rear shell 110 can be less than or equal to the distance between the connecting post and the rear shell 110, so that the wiring structure 414 does not affect the contact between the connecting post and the rear shell 110.

[0173] Please see Figure 9 and Figure 11 In some embodiments of this application, the wiring structure 414 may be disposed above the connecting post. The connecting post is less likely to affect the entry of the third wire harness into the wiring structure 414, thus facilitating the entry of the third wire harness into the wiring structure 414.

[0174] In some embodiments of this application, the wiring structure 414 and the housing together define a wiring groove, which is used to bind a third wire harness passing through the wiring structure 414. The third wire harness can be used to connect the control board (i.e., the washing machine button panel) and the drain pump at the bottom of the drum assembly, etc.

[0175] For example, the third wire harness enters the wiring structure 414 from the end near the clearance opening 425, extends out of the wiring structure 414 from the end near the wire harness outlet 422, and is constrained by the second fixing part 424 near the wire harness outlet 422.

[0176] In some embodiments of this application, the wiring structure 414 includes an upper stop 4141 and a lower stop, the lower stop including a blocking portion 4142. Along a first direction of the housing, i.e., along the width direction of the housing 100, the upper stop 4141 and the blocking portion 4142 are spaced apart, with the upper stop 4141 located on the side of the blocking portion 4142 facing the top surface of the housing 100. One end of the blocking portion 4142 is bent toward the side where the upper stop 4141 is located.

[0177] In some embodiments of this application, a wiring groove is formed between the upper stop 4141 and the stop portion 4142. The wiring groove is configured to fix the third wire harness passing through the wiring structure 414 within the housing 100. The extension direction of the wiring groove is parallel to the length extension direction of the housing, which allows the third wire harness in the wiring groove to be arranged parallel to the housing, thereby reducing the intertwining of the third wire harness with the housing.

[0178] In some embodiments of this application, the upper stop 4141 may be located above the blocking portion 4142. In the vertical direction, the distance between the upper stop 4141 and the connecting post may be greater than the distance between the blocking portion 4142 and the connecting post, which is beneficial for forming a wiring groove between the upper stop 4141 and the blocking portion 4142.

[0179] Please see Figure 9 and Figure 11 In some embodiments of this application, the number of at least one of the upper stop 4141 and the blocking part 4142 is at least two. Along the second direction of the housing, i.e., along the length direction of the housing 100, the upper stop 4141 and the blocking part 4142 are alternately arranged, and the upper stop 4141, the blocking part 4142, and the housing together define a cable routing groove. The upper stop 4141 may include multiple horizontally arranged baffles. The multiple baffles are spaced apart and located on the same horizontal line. The lower space between adjacent baffles may be provided with a blocking part 4142. The blocking part 4142 may include multiple L-shaped baffles. The multiple L-shaped baffles are spaced apart and located on the same horizontal line.

[0180] It should be noted that the side of the box facing the back shell is defined as the back side, and the first direction and the second direction are the two directions in which the box intersects on the back side.

[0181] In some embodiments of this application, the upper stop 4141 and the blocking portion 4142 are spaced apart along the width direction of the housing 100. The upper stop 4141 and the blocking portion 4142 are also spaced apart along the height direction of the housing 100. This facilitates the third wire harness entering the wiring groove through the gap between the upper stop 4141 and the blocking portion 4142.

[0182] In some embodiments of this application, multiple horizontally arranged baffles can be fixedly connected to the base 410, which can improve the stability of the upper baffle 4141.

[0183] In some embodiments of this application, the L-shaped baffle includes a horizontal section and a vertical section. The horizontal section of the L-shaped baffle can be horizontally positioned. The vertical section of the L-shaped baffle can be vertically positioned. The vertical section of the L-shaped baffle is parallel to the base 410.

[0184] In some embodiments of this application, the upper stop 4141 may include a horizontally arranged baffle. The blocking portion 4142 may include an L-shaped baffle. In the horizontal direction, the lengths of the upper stop 4141 and the blocking portion 4142 may be equal to the width of the base 410. A gap is provided between the upper stop 4141 and the blocking portion 4142 to facilitate the fixing of the third wire harness between the upper stop 4141 and the blocking portion 4142.

[0185] Please see Figure 9 In some embodiments of this application, the lower stop further includes a support portion 4143. One end of the blocking portion 4142 connected to the housing is connected to the support portion 4143, and the support portion 4143 is located on the side of the blocking portion 4142 facing the upper stop 4141. The support portion 4143 and the blocking portion 4142 together support the third wire harness.

[0186] In some embodiments of this application, the upper stop 4141 is located on the side of the support portion 4143 facing the top surface of the housing. The upper stop 4141, the blocking portion 4142, the support portion 4143, and the housing together define the wiring groove. The support portion 4143 and the blocking portion 4142 jointly support the third wire harness. The support portion 4143 is located on the side of the blocking portion 4142 along the length direction of the housing. The support portion 4143 forms a relatively flat support surface so that the third wire harness can be straight within the wiring structure 414, and the third wire harness is less prone to bending.

[0187] Please see Figures 6-8 In some embodiments of this application, the base 410 or the cover plate 420 may be provided with heat dissipation holes. These holes can help dissipate the heat of the circuit board inside the control box 400 in a timely manner, reduce or avoid damage to the circuit board due to overheating, and improve the service life of the circuit board.

[0188] In some embodiments of this application, both the base 410 and the cover plate 420 may be provided with heat dissipation holes, which can better dissipate the heat of the control devices in the control box 400 in a timely manner, reduce or avoid damage to the control devices due to overheating, and improve the service life of the control devices.

[0189] In some embodiments of this application, the heat dissipation holes can communicate with the receiving cavity, which can better dissipate the heat inside the receiving cavity.

[0190] In some embodiments of this application, the heat dissipation holes may include multiple rectangular holes. These multiple rectangular holes may be arranged in parallel. Multiple parallel rectangular holes provide a larger ventilation area, which is beneficial for dissipating heat from the cavity.

[0191] In some embodiments of this application, the heat dissipation holes may include multiple circular holes. These multiple circular holes may be evenly distributed on the cover plate 420.

[0192] Please see Figures 7-8In some embodiments of this application, the cover plate 420 may be provided with a through hole. The through hole may be located at one corner of the cover plate 420 to facilitate the installation of other structures. The through hole allows a plug to pass through. The plug can be inserted into the circuit board inside the control box 400 to enable the circuit board to connect with external devices outside the control box 400.

[0193] The installation process for control box 400 is as follows:

[0194] After fixing the circuit board to the base 410, snap the cover plate 420 into the base 410.

[0195] The limiting member 411 is inserted through the mounting port 111 and then slides downward to achieve the connection between the limiting member 411 and the rear shell 110, thereby achieving the pre-connection between the box and the rear shell 110.

[0196] The control box 400 is fixedly connected to the rear shell 110 by the fixing member 412.

[0197] In addition to its basic function of encapsulating the circuit board, the control box 400 also serves to guide and constrain the wiring harness.
