The motor base is connected with a shaft sleeve at both ends. The support comprises two support plates and two limiting plates. The two limiting plates are located on the sides of the two support plates away from each other along a preset direction.

[0002] A ducted air conditioner consists of a fan and a motor.

[0011] In some embodiments, the first edge is coaxial with the cross surface.

[0012] In some embodiments, the abutment is tilted relative to the adjacent support plate.

[0013] In some embodiments, the distance between the abutment and the adjacent support plate gradually increases along the direction from one end of the abutment connecting the support plate to the other end.

[0014] In some embodiments, the inclination angle of the abutment relative to the adjacent support plate is α, where α satisfies: 2°≤α≤10°.

[0015] In some embodiments, the length of the limiting plate is h1 in the direction perpendicular to the carrier plate, where h1 satisfies: 7mm≤h1≤15mm.

[0016] In some embodiments, it also includes: The clamp includes two clamp bodies, each corresponding to a support plate, and both ends of the clamp body are connected to the corresponding support plate to jointly enclose the corresponding bushing.

[0017] In some embodiments, the clamp includes: Two limiting flanges are located on opposite sides of the two hoops along a preset direction and are connected to the adjacent hoops. The limiting flanges abut against the corresponding bushings along the preset direction.

[0018] In some embodiments, the clamp includes: The connector has a connecting end, and the connector connects the connecting ends of two hoops.

[0019] In some embodiments, the clamp is in conductive contact with the support, and the connector is provided with a grounding hole.

[0020] In some embodiments, the connector includes: Two first structural parts are spaced apart along a predetermined direction and extend along a direction intersecting the predetermined direction, and the two first structural parts are respectively connected to two hoop bodies; and, The second structural part is connected to the end of the two first structural parts away from the hoop. The second structural section is equipped with a grounding hole.

[0021] In some embodiments, the connector has a grounding limiting portion protruding from the grounding hole, which is used to limit the grounding terminal when the grounding hole is connected to the grounding terminal of the grounding wire.

[0022] In some embodiments, the grounding limiting portion includes: Two second protrusions are spaced apart around the grounding hole. Each second protrusion has a limiting surface. Along the circumference of the grounding hole, the limiting surfaces of the two second protrusions are arranged facing away from each other. The two limiting surfaces are used to phase the opposite sides of the grounding terminal.

[0023] In some embodiments, it also includes: The first locking member has a first connecting hole in the connecting body and a second connecting hole in the support plate.

This allows the motor's bushing to be partially located within the two limiting ranges and abut against the corresponding limiting plates along a preset direction during motor and support installation. The partial location of the motor's bushing within the limiting range increases the contact area between the motor and the support, thereby improving the connection reliability. The abutment of the motor's bushing against the corresponding limiting plates along the preset direction means that the two limiting plates press against the central base along the motor's axial direction, providing an axial limiting effect during base installation, ensuring the base is centered and less prone to shifting.

[0031] The base is less prone to shifting, making it easier to fix with screws or other methods, which helps improve assembly efficiency. Attached Figure Description

[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] In the following description, when referring to the accompanying drawings, the same numbers in different drawings denote the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0037] This application provides a heating, ventilation, and air conditioning (HVAC) device. There are many types of HVAC devices, such as air conditioners, multi-split systems, heat pumps, and water heaters, which are used to cool or heat the indoor environment and regulate the indoor temperature.

[0038] Heating, ventilation, and air conditioning (HVAC) equipment includes indoor units and outdoor units. The indoor and outdoor units are connected via refrigerant piping, through which refrigerant flows. In this embodiment, the indoor unit includes a ducted air conditioner.

[0039] Please see Figures 1 to 3 The ducted air conditioner 1 includes a housing 10, an electrical control box 20, a heat exchanger 30, a fan 50, and a motor structure 60. The housing 10 has an air duct cavity formed within it, and is equipped with an air inlet 154 and an air outlet (not shown in the figure) communicating with the air duct cavity. The fan 50 is located at the air inlet 154, and a portion of the heat exchanger 30 is located within the air duct cavity. The motor structure 50 is connected to the fan 50 and drives the fan 50 to operate. When the fan 50 operates, airflow enters the air duct cavity through the air inlet 154, passes through the heat exchanger 30, exchanges heat with the heat exchanger 30, and then flows out through the air outlet, achieving cooling or heating. At least a portion of the housing 10 is recessed to form a receiving groove, and at least a portion of the electrical control box 20 is located in the receiving groove and rests against the bottom of the receiving groove.

[0040] The casing 10 includes a partition 15, which has an air inlet 154. An air duct cavity and a fan cavity are formed within the casing 10. The partition 15 is located between the air duct cavity and the fan cavity, and the air inlet 154 connects the air duct cavity and the fan cavity. The fan 50 is located in the fan cavity. Specifically, the air outlet of the fan 50 installed in the fan cavity can be configured corresponding to the air inlet 154, so that when the fan 50 is operating, airflow can enter the air duct cavity from the air inlet 154 and exchange heat through the heat exchanger 30 in the air duct cavity.

[0041] Both the fan 50 and the motor structure 60 can be installed on the middle partition 15.

[0042] The partition 15 is connected to a connecting bracket 156, and the motor structure 60 is mounted on the connecting bracket 156. The motor structure 60 can be mounted on the connecting bracket 156 by means of screws or other means, and there is no limitation thereto.

[0043] See Figures 3 to 5 The connecting bracket 156 is provided with a flange 1561, and the motor structure 60 is provided with a limiting port 634, into which the flange 1561 extends. The flange 1561 and the limiting port 634 can provide a positioning effect for the installation of the motor structure 60 and the connecting bracket 156, thereby improving the accuracy of the connection between the two.

[0044] The protrusion height of the flange 1561 relative to the connecting bracket 156 is h2, where h2 satisfies: 3mm ≤ h2 ≤ 10mm. By reasonably limiting the protrusion height h2 of the flange 1561 relative to the connecting bracket 156, the flange 1561 can both extend into the limiting opening 634 of the motor structure 60 to provide a positioning effect during the installation of the motor structure 60 and the connecting bracket 156, and also ensure that the flange 1561 has sufficient structural strength and is not easily bent or deformed. In some embodiments, h2 can be 3mm, 5mm, 7mm, 9mm, 10mm, etc.

[0045] See Figure 6 The motor structure 60 includes a motor 61, a clamp 62, and a support 63. The support 63 is provided with a limit port 634 and is installed on the connecting frame 156 of the middle partition 15.

[0046] See Figures 6 to 10 The motor 61 includes a base 611, with bushings 6111 connected to both axial ends of the base 611. The support 63 includes two support plates 631 and two limiting plates 632. The two support plates 631 are positioned opposite each other and spaced apart along a predetermined direction n. The two limiting plates 632 are located along the predetermined direction n on opposite sides of the two support plates 631 and are connected to the adjacent support plate 631. The limiting plates 632 form a limiting range 632a on the side of the adjacent support plate 631.

[0047] In this case, the preset direction n is along the axial direction of the motor 61, and the two bushings 6111 of the base 611 are respectively partially located in the two limiting intervals 632a, and abut against the corresponding limiting plate 632 along the preset direction n.

[0048] By designing the support 63 to include two limiting plates 632, which form a limiting interval 632a, when the motor 61 is installed with the support 63, the bushing 6111 of the motor 61 can be partially located within the two limiting intervals 632a and abut against the corresponding limiting plate 632 along a preset direction n. The fact that the bushing 6111 of the motor 61 is partially located within the limiting interval 632a helps to increase the contact area between the motor 61 and the support 63, thereby improving the reliability of the connection between the motor 61 and the support 63. The bushing 6111 of the motor 61 abuts against the corresponding limiting plate 632 along the preset direction n; that is, the two limiting plates 632 press against the central base 611 along the axial direction of the motor 61, which can achieve an axial limiting effect when the base 611 is installed, ensuring that the base 611 is centered during installation and is less prone to displacement.

[0049] The 611 base is less prone to shifting, making it easier to fix with screws or other methods, which helps improve assembly efficiency.

[0050] Next, see Figure 11 and Figure 12 The motor 61 will be described in detail.

[0051] The motor 61 includes a base 611 and an output shaft 612. The base 611 is fixed relative to the housing 10 (middle partition 15). The output shaft 612 connects the base 611 and the fan 50. The output shaft 612 can rotate relative to the base 611 to drive the fan 50 to rotate and work.

[0052] The motor 61 includes two output shafts 612 connected to the same base 611. Each of the two output shafts 612 is connected to a fan 50. Each fan 50 is set with an air inlet 154, so that when the motor 61 is working, it can drive the two fans 50 to work, increase the air flow into the casing 10, and improve the cooling or heating effect.

[0053] Motor 61 connects to two fans 50, which saves space and is easier to install compared to setting two motors to connect to two fans separately.

[0054] The machine base 611 has bushings 6111 connected to both ends of its axial direction. The bushings 6111 are fixed relative to the machine base 611, and the output shaft 612 passes through the bushings 6111. The bushings 6111 are smaller in size than the machine base 611. When fixing the machine base 611, the bushings 6111 on the machine base 611 can be selected for fixing, which makes the operation more convenient.

[0055] Bushings 6111 are provided at both ends of the axial direction of the base 611, which facilitates fixing the bushings 6111 at both ends of the axial direction of the base 611 and improves the stability of the base 611 relative to the housing 10.

[0056] The bushing 6111 has a circumferential surface 6112, which can be used to fix the bushing 6111 and the motor 61. The circumferential surface 6112 is arranged around the axial direction, that is, the circumferential surface 6112 is approximately a cylindrical surface around the axial direction of the motor 61. In this way, when fixing the bushing 6111 through the circumferential surface 6112, it is convenient to adjust the axial orientation of the motor 61 so that its axial position after installation meets the requirements.

[0057] The circumferential surface 6112 is provided with a mounting groove 6113. When fixing the circumferential surface 6112, the mounting groove 6113 allows part of the structure to extend into the mounting groove 6113, increasing the contact area and playing a positioning role, thereby improving the stability and accuracy of fixing the bushing 6111.

[0058] The mounting slot 6113 can be an annular slot around the axis of the motor 61, and there is no limitation thereto.

[0059] The bushing 6111 can be a rubber bushing, and there are no restrictions on this.

[0060] Next, see Figure 7 , Figure 9 , Figure 13 and Figure 14 The clamp 62 is described in detail.

[0061] The clamp 62 has an inner side 62a and an outer side 62b, with the inner side 62a facing the bushing 6111 and the outer side 62b facing away from the bushing 6111.

[0062] The clamp 62 includes two clamp bodies 621, which are spaced apart along a preset direction n, and the two clamp bodies 621 correspond to two bushings 6111 respectively.

[0063] The hoop 621 is used together with the support 63 to enclose the corresponding bushing 6111, so as to fix the bushing 6111.

[0064] The hoop 621 is roughly arc-shaped and is coaxially arranged with the circumferential surface 6112 of the bushing 6111, which improves the fit between the hoop 621 and the circumferential surface 6112 of the bushing 6111, so as to better fix the bushing 6111.

[0065] The hoop 621 bulges inward from the inner side 62a to the outer side 62b to form an arc shape.

[0066] The hoop 621 has a first protrusion 6211, which extends into the mounting groove 6113 of the bushing 6111, increasing the contact area between the hoop 621 and the bushing 6111 and serving as a positioning effect when assembling the hoop 621 and the bushing 6111, thereby improving the stability and accuracy of the bushing 6111.

[0067] The hoop 621 has a first protrusion 6211 protruding on its inner side 62a.

[0068] The hoop 621 includes a plurality of first protrusions 6211 spaced apart along its length, so that when the hoop 621 is assembled with the bushing 6111, the positions of the plurality of first protrusions 6211 are all positioned.

[0069] The first protrusion 6211 can be formed by processes such as punching, and there are no restrictions on this.

[0070] The hoop 621 has a suspension end 6212, and the suspension end 6212 is provided with a locking hole 6213.

[0071] The hoop 621 has a connecting end 6214, and the connecting end 6214 and the suspension end 6212 are the two ends of the hoop 621 in the length direction.

[0072] The clamp 62 includes two limiting flanges 622, which are located on opposite sides of the two clamp bodies 621 along a preset direction n and connected to the adjacent clamp body 621. The limiting flanges 622 abut against the corresponding bushings 6111 along the preset direction n. In this way, the two limiting flanges 622 press against the central base 611 along the axial direction of the motor 61, which can achieve the axial limiting effect of the base 611 during installation, so that the base 611 is centered during installation.

[0073] The limiting flange 622 and the limiting plate 632 correspond to different parts of the bushing 6111, so that under the common axial pressure of the limiting flange 622 and the limiting plate 632, the installation accuracy of the machine base 611 along the axial direction is higher.

[0074] The limiting fold 622 is folded inwards towards the inner side 62a relative to the hoop 621. The forming process is simple, and the limiting fold 622 and the hoop 621 are integrated into one piece, which increases the structural strength.

[0075] The clamp 62 includes a connector 623, which connects the connector ends 6214 of the two clamp bodies 621 to connect the two clamp bodies 621 into one unit, thereby realizing the integrated design of the clamp 62.

[0076] The connecting body 623 includes two first structural portions 6232 and a second structural portion 6233. The two first structural portions 6232 are spaced apart along a predetermined direction n and extend in a direction intersecting the predetermined direction n, and the two first structural portions 6232 are respectively connected to two hoop bodies 621. The second structural portion 6233 connects to the end of the two first structural portions 6232 away from the hoop body 621. In this way, the connecting body 623 can be kept away from the base 611 of the hoop body 621, and will not interfere with the base 611.

[0077] The first structural part 6232 is roughly in the shape of a thin plate.

[0078] The two first structural parts 6232 are arranged approximately in the same plane.

[0079] The second structural part 6233 is roughly in the shape of a thin plate.

[0080] The second structural part 6233 is arranged approximately on the same plane as the first structural part 6232.

[0081] The connector 623 is provided with a grounding hole 6231, which enables the clamp 62 to integrate grounding function. Screws or other fasteners can be inserted through the grounding hole 6231 to fix the grounding terminal of the grounding wire to the grounding hole 6231.

[0082] The grounding hole 6231 has a chamfer on the outer side 62b of the clamp 62 so that the screw can pass through the outer side 62b of the clamp 62, making the connection of the grounding wire more convenient.

[0083] The grounding hole 6231 extends into a connecting post 6231a on the inner side 62a of the clamp 62 to improve the reliability of the connection with the screw.

[0084] The number of grounding holes 6231 can be one or multiple at intervals, depending on actual needs, and there is no limitation on this.

[0085] The second structural part 6233 is provided with a grounding hole 6231. The second structural part 6233 is separated from the base 611. Therefore, the grounding hole 6231 is provided in the second structural part 6233 to avoid the grounding wire from interfering with the base 611 and the motor 61 when the grounding hole 6231 is connected.

[0086] Furthermore, the second structural part 6233 is larger in size than the first structural part 6232, which makes it easier to set the grounding hole 6231.

[0087] The connector 623 can be a conductive component to facilitate conductive contact with other structural components and achieve grounding functionality. In this embodiment, the entire clamp 62 is a metal component with conductive properties, which facilitates grounding functionality. Specifically, the clamp 62 can be a sheet metal component.

[0088] The connector 623 has a grounding limiting part 6234 protruding from the grounding hole 6231. The grounding limiting part 6234 is used to limit the grounding terminal when the grounding hole 6231 is connected to the grounding terminal of the grounding wire.

[0089] Normally, when connecting a grounding wire to the grounding hole 6231, the grounding terminal of the grounding wire needs to be fixed to the grounding hole by means of screws or the like. However, during the screwing process, the grounding terminal may rotate with the screw. Therefore, the grounding limiting part 6234 limits the grounding terminal to avoid the problem of the grounding terminal rotating with the screw when it is tightened.

[0090] The grounding limiting part 6234 includes two second protrusions 6235, which are spaced apart around the grounding hole 6231. Each second protrusion 6235 has a limiting surface 6236. Along the circumference of the grounding hole 6231, the limiting surfaces 6236 of the two second protrusions 6235 are arranged facing away from each other. The two limiting surfaces 6236 are used to phase the opposite sides of the grounding terminal.

[0091] When connecting the grounding wire to the grounding hole 6231, the grounding terminal of the grounding wire can be positioned between the two second protrusions 6235, with both ends corresponding to the two second protrusions 6235 respectively, and the opposite sides of the grounding terminal corresponding to the two limiting surfaces 6236 respectively. Thus, when tightening the screw, the tightening direction of the screw is consistent with the direction in which the end of the grounding terminal faces the adjacent limiting surface 6236. For example... Figure 13 In the middle, tightening the screw in a clockwise direction will constrain the grounding terminals of the limiting surface 6236 as the screw rotates.

[0092] The projection of the second protrusion 6235 is approximately triangular. The second protrusion 6235 can be formed by processes such as stamping, and there is no limitation on this.

[0093] The grounding limiting part 6234 and the second protrusion 6235 are located on the outer side 62b of the clamp 62 to limit the grounding terminal at the outer side 62b.

[0094] The connector 623 is provided with a first connecting hole 6237, which can be fixed to the support 63 by a locking member.

[0095] The clamp 62 includes a reinforcing flange 624, which connects to the outer edge of the connector 623 and is folded relative to the connector 623. The reinforcing flange 624 helps to improve the structural strength of the clamp 62, and the connection between the reinforcing flange 624 and the connector 623 can avoid interfering with the assembly of the clamp body 621 and the base 611.

[0096] The distribution direction of the reinforcing flange 624 and the connecting body 623 is consistent with the distribution direction of the inner side 62a and the outer side 62b of the clamp 62. That is, the reinforcing flange 624 is located on the inner side of the clamp 62 and will not interfere with the connection of the outer side 62b.

[0097] The reinforcing fold 624 includes two first reinforcing portions 6241 and a second reinforcing portion 6242. The two first reinforcing portions 6241 are respectively connected to the outer edges of the two first structural portions 6232 and are folded relative to the first structural portions 6232. The second reinforcing portion 6242 is connected to the outer edge of the second structural portion 6233 and is folded relative to the second structural portion 6233.

[0098] The second reinforcing part 6242 is connected to the two first reinforcing parts 6241, further enhancing the structural strength of the clamp 62.

[0099] The second reinforcing part 6242 is smoothly connected to the two first reinforcing parts 6241 to ensure the surface flatness of the clamp 62 and avoid scratching hands.

[0100] The clamp 62 is a one-piece molded part with good structural strength and easy assembly, which is beneficial for market after-sales maintenance.

[0101] Next, see Figure 15 and Figure 16 The support 63 is described in detail.

[0102] The support 63 is in conductive contact with the clamp 62, and the support 63 is also in conductive contact with the housing 10 (middle partition 15), realizing the integrated grounding function of the clamp 62.

[0103] The entire support 63 is made of metal and has electrical conductivity, which facilitates conductive contact with the clamp 62 and the housing 10. Specifically, the support 63 can be a sheet metal part.

[0104] The support 63 includes two support plates 631, which are arranged opposite each other and spaced apart along a preset direction n. Two hoop bodies 621 correspond to the two support plates 631 respectively, and both ends of the hoop bodies 621 are connected to the corresponding support plates 631 to jointly enclose the corresponding bushings 6111 with the support plates 631.

[0105] The support plate 631 is provided with a hook 6315, which passes through the locking hole 6213 of the hoop 621 and hooks the hoop 621.

[0106] The support plate 631 is provided with a second connecting hole 6316. The motor structure 60 also includes a first locking member (not shown in the figure). The first locking member passes through the first connecting hole 6237 of the connecting body 623 in the clamp 62 and the second connecting hole 6316 of the support plate 631, and connects the connecting body 623 to the support plate 631. The first locking member can realize the connection between the connecting body 623 and the support plate 631, and thus realize the connection between the clamp 62 and the support 63.

[0107] Specifically, when the clamp 62 is connected to the support 63, the locking holes 6213 of the two suspension ends 6212 of the clamp 62 fit onto the hooks 6315 of the support plate 631. Using this as a fulcrum, the clamp 62 is flipped so that it is upside down onto the bushings 6111 on both sides of the machine base 611. The limiting flange 622 of the clamp 62 abuts against the bushings 6111 axially to prevent the machine base 611 from deviating to the left or right and coming off after assembly. After assembly, the first connecting hole 6237 of the clamp 62 and the second connecting hole 6316 of the support plate 631 are fastened together by the first locking element.

[0108] The support plate 631 and the connector 623 can make conductive contact at the first locking member, thereby achieving conductive contact between the clamp 62 and the support 63. Since the relative positions of the support plate 631 and the connector 623 are not easily changed after being fixed by the first locking member, achieving conductive contact between the two at this position can make the conductive contact more reliable.

[0109] The support plate 631 has a mounting opening 6311 with a first edge 6312. The bushing 6111 is located in the mounting opening 6311, and the first edge 6312 extends into the mounting groove 6113 of the bushing 6111.

[0110] The first edge 6312 is coaxially arranged with the circumferential surface 6112 of the bushing 6111, so that the first edge 6312 extends into the mounting groove 6113 of the bushing 6111, which can constrain the axial direction of the bushing 6111 and improve its axial installation accuracy.

[0111] The support plate 631 has a clearance opening 6313, which is connected to the mounting opening 6311. The clearance opening 6313 has a second edge 6314, which is separated from the first edge 6312.

[0112] The support 63 includes two limiting plates 632, which are located on opposite sides of the two support plates 631 along a preset direction n and are connected to the adjacent support plate 631. The limiting plates 632 form a limiting interval 632a on the side of the adjacent support plate 631. The preset direction n is along the axial direction of the motor 61. The two bushings 6111 of the base 611 are partially located in the two limiting intervals 632a and abut against the corresponding limiting plates 632 along the preset direction n.

[0113] The bushing 6111 of the motor 61 is located in the limiting range 632a, which helps to increase the contact area between the motor 61 and the support 63, thereby improving the connection reliability between the motor 61 and the support 63. The bushing 6111 of the motor 61 abuts against the corresponding limiting plate 632 along the preset direction n. That is, the two limiting plates 632 press against the middle base 611 along the axial direction of the motor 61, which can play an axial limiting effect when the base 611 is installed, so that the base 611 is centered during installation and is not easy to deviate.

[0114] The 611 base is less prone to shifting, making it easier to fix with screws or other methods, which helps improve assembly efficiency.

[0115] The circumferential surfaces 6112 of the two bushings 6111 are respectively mounted on the two limiting plates 632. In this way, the limiting plates 632 can provide support and positioning for the circumferential surfaces 6112 of the bushings 6111. The bushings 6111 on both sides are mounted on the corresponding carrier plates 6321, which helps to improve the consistency of the axial installation height on both sides of the base 611. This ensures that the concentricity of the motor 61 after assembly is limited and supported, guarantees concentricity, improves the overall operating stability of the machine, and reduces the vibration and noise of the machine.

[0116] The limiting plate 632 is connected to the second edge 6314. The limiting plate 632 is connected to the second edge 6314 which is separated from the first edge 6312, so that the peripheral surface 6112 can be placed on the limiting plate 632 and the first edge 6312 can extend into the mounting groove 6113 of the peripheral surface 6112, thereby realizing multiple limiting between the support 63 and the base 611.

[0117] The limiting plate 632 includes a carrier plate 6321 and a stop plate 6322. The carrier plate 6321 is connected to an adjacent support plate 631 and extends away from the other support plate 631. The stop plate 6322 is connected to the end of the carrier plate 6321 away from the support plate 631 and extends in a direction opposite to and spaced from the support plate 631 along a predetermined direction n. A limiting interval 632a is formed between the stop plate 6322 and the carrier plate 6321, and the bushing 6111 supports the carrier plate 6321.

[0118] The carrier plate 6321 has a cross surface 6321a that participates in constructing the limiting section 632a. The cross surface 6321a is adapted to the circumferential surface 6112 of the bushing 6111, and the circumferential surface 6112 rests on the cross surface 6321a. The adaptation of the cross surface 6321a and the circumferential surface 6112 realizes the surface contact between the bushing 6111 and the carrier plate 6321, further improving the consistency of the installation height on both sides of the axial direction of the base 611.

[0119] The cross surface 6321a and the first edge 6312 are coaxially arranged so that both the cross surface 6321a and the first edge 6312 can improve the consistency of the installation height on both sides of the axial direction of the base 611.

[0120] The abutment plate 6322 is inclined relative to the adjacent support plate 631.

[0121] Along the direction from one end of the abutment plate 6322 to the other end of the carrier plate 6321, the distance between the abutment plate 6322 and the adjacent support plate 631 gradually increases. This facilitates the bushing 6111 entering the limiting range 632a.

[0122] The inclination angle α between the abutment plate 6322 and the adjacent support plate 631 satisfies: 2° ≤ α ≤ 10°. By reasonably limiting the inclination angle α between the abutment plate 6322 and the adjacent support plate 631, it is possible to facilitate the entry of the bushing 6111 into the limiting range 632a, and the abutment plate 6322 can abut against the base 611 in a preset direction n. In some embodiments, α can be 2°, 4°, 6°, 8°, 10°, etc.

[0123] In the direction perpendicular to the carrier plate 6321, the length of the limiting plate 632 is h1, where h1 satisfies: 7mm ≤ h1 ≤ 15mm. By reasonably limiting the length h1 of the limiting plate 632 in the direction perpendicular to the carrier plate 6321, the limiting plate 632 can effectively limit and constrain the base 611, making it less likely for the base 611 to detach from the limiting range 632a. In some embodiments, h1 can be 7mm, 9mm, 11mm, 13mm, 15mm, etc.

[0124] The support 63 includes a connecting plate 633, which is connected between two support plates 631.

[0125] The connecting plate 633 is installed on the connecting bracket 156 of the middle partition 15. The connecting plate 633 is provided with a limit port 634.

[0126] The two support plates 631 are located on the same side of the connecting plate 633, and the connecting plate 633 is attached to the connecting frame 156 on the side opposite to the support plate 631.

[0127] Support 63 is a one-piece molded part.
