[0045] The present application is described below with reference to specific embodiments and with reference to the accompanying drawings:

[0046] The air conditioner provided in this embodiment is intended to at least to some extent solve the technical problem that the bearing bracket is usually designed as an independent component and installed on the middle partition, resulting in a large number of parts and increased costs.

[0047] Figure 1 is a schematic structural diagram of an air conditioner according to some embodiments; Figure 2 for Figure 1 A in the middle is an enlarged schematic diagram; Figure 4 for Figure 1 Schematic diagram of the arrangement of the middle partition of the central air conditioner; Figure 5 for Figure 1 Schematic diagram of the structure of the middle partition. Figure 1 、 Figure 2 、 Figure 4 and Figure 5 The air conditioner of the present embodiment includes: a middle partition 10, a bearing bracket 60, and a bearing 70. A first volute 20 and an impeller 30 disposed within the first volute 20 are mounted on the middle partition 10. A bearing bracket 60 and a bearing 70 disposed therein are mounted on the middle partition 10, and the bearing 70 is connected to a rotating shaft 80 of a fan assembly. The middle partition 10, first volute 20, support frame 40, and bearing bracket 60 are integrally formed by injection molding.

[0048] The driver 50 may be a motor.

[0049] Since the bearing bracket 60 and the bearing 70 provided on the bearing bracket 60, the bearing bracket 60 is installed on the intermediate partition 10, and the bearing 70 is connected to the rotating shaft 80 of the fan assembly, the bearing bracket 60 is supported by the intermediate partition 10, and the bearing 70 can be installed on the bearing bracket 60, and the bearing 70 is supported by the bearing bracket 60, and the bearing 70 can support the rotating shaft 80 of the fan assembly. Since the intermediate partition 10 and the bearing bracket 60 are injection-molded as one piece, the bearing bracket 60 is integrated on the intermediate partition 10, that is, the intermediate partition 10 has a bearing mounting position, and the intermediate partition 10 is installed in the housing 110 of the air conditioner. The assembly of the bearing 70 can be achieved through an intermediate partition 10, which can reduce The reduced number of parts reduces the cost of the entire process including manufacturing, transportation, storage, and production. Moreover, the bearing 70 can be assembled in the air conditioner housing 110 by only installing the middle partition 10 in the air conditioner housing 110. There is no need to install the bearing bracket 60 in the air conditioner housing 110, which reduces assembly actions and improves production efficiency. The position of the bearing bracket 60 on the middle partition 10 is determined, which reduces assembly errors caused by multi-part assembly and improves assembly accuracy. At the same time, the middle partition 10 and the bearing bracket 60 exist as a whole. During maintenance, only the middle partition 10 needs to be replaced. There is no need to stock multiple spare parts separately, which reduces inventory costs, simplifies the spare parts management process, and reduces maintenance difficulty.

[0050] In some embodiments, the middle partition 10 and the bearing bracket 60 are injection molded as one piece, which can achieve a seamless connection between the middle partition 10 and the bearing bracket 60, enhance the structural strength, and improve the stability and durability of the product. Moreover, during the manufacturing process, the position of the bearing bracket 60 on the middle partition 10 can be accurately fixed, which can eliminate the installation errors that may occur in the subsequent assembly process, ensure the precise fit between the components, and thus improve the overall performance and reliability of the product. At the same time, the injection molding design simplifies the structure composed of the middle partition 10 and the bearing bracket 60 into an integral component. During the production process, the manufacturing, storage, transportation and assembly costs of multiple components can be saved. The reduction in the number of components directly reduces the complexity and management difficulty of the production process, thereby reducing the overall cost.

[0051] In some embodiments, the middle partition 10 and the bearing bracket 60 are formed by one-piece injection molding, that is, the material of the middle partition 10 and the bearing bracket 60 is plastic. Compared with sheet metal one-piece molding, because plastic can fill and replicate the shape of the mold well in the mold, one-piece injection molding can produce products with complex geometric shapes and precise details, so that the middle partition 10 and the bearing bracket 60 meet the use requirements. Moreover, the one-piece injection molding process can realize continuous and high-speed injection molding. The entire injection molding process (injection molding, cooling, demolding, etc.) is carried out continuously, reducing the production cycle and conversion time, and improving work efficiency. At the same time, the one-piece injection molding process can complete multiple steps in one operation, reducing the production cycle and manual intervention, and can reduce the assembly process between the middle partition 10 and the bearing bracket 60, and also reduce the error rate and rework rate on the assembly line, further improving production efficiency and product quality.

[0052] Combine Figure 1 and Figure 2 In some embodiments, to further reduce costs, the air conditioner further comprises: a first volute 20, an impeller 30, a support frame 40, and a driver 50. The first volute 20 and the impeller 30 disposed therein are mounted on the intermediate partition 10. The support frame 40 and the driver 50 disposed thereon are mounted on the intermediate partition 10. The intermediate partition 10, the first volute 20, the support frame 40, and the bearing bracket 60 are integrally formed by injection molding.

[0053] In some embodiments, since the first volute 20 and the impeller 30 provided in the first volute 20 are installed on the middle partition 10, the first volute 20 is supported by the middle partition 10, and the impeller 30 can be installed on the first volute 20, and the impeller 30 is accommodated by the first volute 20. Since the support frame 40 and the driver 50 provided on the support frame 40 are installed on the middle partition 10, the support frame 40 is supported by the middle partition 10, and the driver 50 can be installed on the support frame 40, and the driver 50 is supported by the support frame 40. Since the middle partition 10, the first volute 20, the support frame 40 and the bearing bracket 60 are injection molded as one piece, the support frame 40, the first volute 20 and the bearing bracket 60 are integrated on the middle partition 10, that is, the middle partition 10 has a driver mounting position, an impeller mounting position and a bearing mounting position. The middle partition 10 is installed in the housing 110 of the air conditioner, and the driver 50 can be realized through a middle partition 10. The assembly of the driver 50, impeller 30 and bearing 70, that is, one part can realize the installation and fixation of three components, can reduce the number of parts and components, and reduce the cost of the entire process such as manufacturing, transportation, storage, and production. Moreover, it is only necessary to install the middle partition 10 in the housing 110 of the air conditioner to realize the assembly of the driver 50, impeller 30 and bearing 70 in the housing 110 of the air conditioner. There is no need to install the support frame 40, the first volute 20 and the bearing bracket 60 in the housing 110 of the air conditioner one by one, which reduces the assembly action and improves production efficiency. The positions of the support frame 40, the first volute 20 and the bearing bracket 60 on the middle partition 10 are determined, which reduces the assembly error caused by the assembly of multiple parts and improves the assembly accuracy. At the same time, the middle partition 10, the support frame 40, the first volute 20 and the bearing bracket 60 exist as a whole. During maintenance, only the middle partition 10 needs to be replaced. There is no need to stock multiple spare parts separately, which reduces inventory costs, simplifies the spare parts management process, and reduces the difficulty of maintenance.

[0054] In some embodiments, the middle partition 10, the support frame 40, the first volute 20 and the bearing bracket 60 are injection molded as one piece, which can achieve seamless connection between the middle partition 10 and the support frame 40, the first volute 20 and the bearing bracket 60, enhance the structural strength, and improve the stability and durability of the product. Moreover, during the manufacturing process, the support frame 40, the first volute 20 and the bearing bracket 60 can be accurately fixed on the middle partition 10, which can eliminate the installation errors that may occur in the subsequent assembly process, ensure the precise fit between the components, and thus improve the overall performance and reliability of the product. At the same time, the injection molding design simplifies the structure composed of the middle partition 10, the support frame 40, the first volute 20 and the bearing bracket 60 into an integral component. During the production process, the manufacturing, storage, transportation and assembly costs of multiple components can be saved. The reduction in the number of components directly reduces the complexity and management difficulty of the production process, thereby reducing the overall cost.

[0055] Combine Figure 1 and Figure 2 In some embodiments, in order to enable the driver 50 to drive the impeller 30 to rotate, one end of the rotating shaft 80 is connected to the action end of the driver 50, and the other end is passed through the impeller 30 and connected to the bearing 70. Among them, the fixed end of the driver 50 is provided on the support frame 40.

[0056] In some embodiments, when air is to be supplied, the driver 50 is activated, the action end of the driver 50 drives the rotating shaft 80 to rotate, and the rotating shaft 80 drives the impeller 30 to rotate to achieve air supply. At this time, the bearing 70 supports the rotating shaft 80 to ensure the stability of the rotation of the rotating shaft 80.

[0057] In some embodiments, since the middle partition 10, the first volute 20, the support frame 40 and the bearing support 60 are injection molded as one piece, the positions of the middle partition 10, the first volute 20, the support frame 40 and the bearing support 60 can be ensured to be accurate. When the impeller 30 is installed on the first volute 20, the driver 50 is installed on the support frame 40, the bearing 70 is installed on the bearing support 60, and the rotating shaft 80 is connected to the bearing 70, the impeller 30 and the driver 50, the coaxiality of the rotating shaft 80, the bearing 70, the impeller 30 and the driver 50 can be ensured, thereby reducing the probability of the impeller 30 rubbing against the first volute 20 and generating abnormal noise due to axial non-concentricity during the rotation of the impeller 30, and the vibration of the entire machine caused by the rotation and shaking of the connecting shaft coupling, thereby ensuring the stability of the equipment operation.

[0058] In some embodiments, in order to facilitate the driver 50 to drive the impeller 30 to rotate, the first volute 20, the support frame 40 and the bearing bracket 60 are all located on the same side of the middle partition 10. The driver 50 can directly drive the impeller 30 to rotate through the rotating shaft 80. Moreover, the rotating shaft 80 can directly reach the bearing bracket 60 to be supported by the bearing 70 at the bearing bracket 60, thereby ensuring the stability of the driver 50 driving the impeller 30 to rotate. At the same time, it facilitates the arrangement of the first volute 20, the support frame 40 and the bearing bracket 60, and effectively utilizes the space inside the air conditioner casing 110.

[0059] Combine Figure 1 In some embodiments, in order to ensure the air outlet volume, multiple first volutes 20 are arranged between the support frame 40 and the bearing support 60, and each first volute 20 is provided with an impeller 30. When cooling or heating is required, the impeller 30 rotates in the first volute 20. The arrangement of multiple first volutes 20 is equivalent to constructing multiple air flow channels between the support frame 40 and the bearing support 60. Compared with one first volute 20, the air flow channels can be increased. The rotation of the impeller 30 can guide the air to flow smoothly, increase the air flow rate, and improve the air circulation efficiency, so that the air can exchange heat with the heat exchanger of the air conditioner faster, ensuring the heat exchange efficiency, thereby improving the cooling or heating effect. In the scenario where the indoor temperature needs to be adjusted quickly, multiple first volutes 20 can guide the air flow faster, accelerate the change of indoor temperature, and meet the user's demand for comfort.

[0060] Figure 6 for Figure 4 Rear view of the middle partition. Figure 4 and Figure 6 In some embodiments, to support the electric auxiliary heater 130, the air conditioner further includes an electric auxiliary heater bracket 90. The electric auxiliary heater bracket 90 is provided on the middle partition 10 and is integrally molded with the middle partition 10 and the bearing bracket 60 by injection molding. The electric auxiliary heater 130 can be supported by the electric auxiliary heater bracket 90. When the air conditioner is required to heat, the electric auxiliary heater 130 serves as an additional heat source, providing additional heat output when the air conditioner's heating capacity is insufficient, significantly improving the indoor heating effect. Moreover, the electric auxiliary heater 130 directly converts electrical energy into thermal energy, resulting in a fast heating speed, which can quickly increase the indoor temperature and meet the user's demand for rapid heating.

[0061] In some embodiments, the electric auxiliary heating bracket 90 is integrated on the middle partition 10, that is, the middle partition 10 has an electric auxiliary heater installation position, and the middle partition 10 is installed in the housing 110 of the air conditioner. The driver 50, the impeller 30, the bearing 70 and the electric auxiliary heater 130 can be assembled through the middle partition 10, that is, one part can realize the installation and fixation of four devices, which can reduce the number of parts and components and reduce the cost of the entire process such as manufacturing, transportation, storage and production. Moreover, only the middle partition 10 needs to be installed in the housing 110 of the air conditioner to realize the assembly of the driver 50, the impeller 30, the bearing 70 and the electric auxiliary heater 130 in the housing 110 of the air conditioner. 0, there is no need to install the support frame 40, the first volute 20, the bearing bracket 60 and the electric auxiliary heating bracket 90 one by one in the housing 110 of the air conditioner, which reduces assembly operations and improves production efficiency. The positions of the support frame 40, the first volute 20, the bearing bracket 60 and the electric auxiliary heating bracket 130 on the middle partition 10 are fixed, which reduces assembly errors caused by assembly of multiple parts and improves assembly accuracy. At the same time, the middle partition 10, the support frame 40, the first volute 20, the bearing bracket 60 and the electric auxiliary heating bracket 90 exist as a whole. During maintenance, only the middle partition 10 needs to be replaced, and there is no need to stock multiple spare parts separately, which reduces inventory costs, simplifies the spare parts management process, and reduces maintenance difficulty.

[0062] In some embodiments, the middle partition 10, the support frame 40, the first volute 20, the bearing bracket 60 and the electric auxiliary heating bracket 90 are injection molded as one piece, which can achieve seamless connection between the middle partition 10 and the support frame 40, the first volute 20, the bearing bracket 60 and the electric auxiliary heating bracket 90, thereby enhancing the structural strength and improving the stability and durability of the product. Moreover, during the manufacturing process, the positions of the support frame 40, the first volute 20, the bearing bracket 60 and the electric auxiliary heating bracket 90 on the middle partition 10 can be accurately fixed, which can eliminate the installation errors that may occur in the subsequent assembly process, ensure the precise fit between the components, and thus improve the overall performance and reliability of the product. At the same time, the injection molding design simplifies the structure composed of the middle partition 10, the support frame 40, the first volute 20, the bearing bracket 60 and the electric auxiliary heating bracket 90 into an integral component. During the production process, the manufacturing, storage, transportation and assembly costs of multiple components can be saved. The reduction in the number of components directly reduces the complexity and management difficulty of the production process, thereby reducing the overall cost.

[0063] In some embodiments, in order to prevent the electric auxiliary heating bracket 90 from interfering with the installation of the impeller 30, the driver 50 and / or the bearing 70, the electric auxiliary heating bracket 90 and the first volute 20, the support frame 40 and the bearing bracket 60 are respectively located on opposite sides of the middle partition 10, so that the installation of the electric auxiliary heater 130 does not interfere with the installation of the impeller 30, the driver 50 and / or the bearing 70, thereby facilitating the installation of the electric auxiliary heater 130, the impeller 30, the driver 50 and the bearing 70.

[0064] In some embodiments, since the electric auxiliary heating bracket 90 and the first volute 20, the support frame 40 and the bearing bracket 60 are respectively located on opposite sides of the middle partition 10, when the driver 50 drives the impeller 30 to rotate, the air flow can pass through the electric auxiliary heater 130, and the air flow can exchange heat with the electric auxiliary heater 130 to improve the indoor heating effect.

[0065] Combine Figure 6 In some embodiments, in order to facilitate supporting the electric auxiliary heater 130, the electric auxiliary heater bracket 90 includes: a first mounting portion 901 and a second mounting portion 902. The first mounting portion 901 is provided on the middle partition 10 and is integrally formed with the middle partition 10 and the bearing bracket 60 by injection molding. The second mounting portion 902 is spaced apart from the first mounting portion 901 and is integrally formed with the middle partition 10 and the bearing bracket 60 by injection molding. The two ends of the electric auxiliary heater 130 are respectively connected to the first mounting portion 901 and the second mounting portion 902. The first mounting portion 901 and the second mounting portion 902 respectively support the two ends of the electric auxiliary heater 130, so as to facilitate the installation of the electric auxiliary heater 130 and ensure the stability of supporting the electric auxiliary heater 130.

[0066] In some embodiments, in order to facilitate the installation of the electric auxiliary heater 130, the two ends of the electric auxiliary heater 130 are respectively connected to the first mounting part 901 and the second mounting part 902, one end of the electric auxiliary heater 130 is plugged into one of the first mounting part 901 and the second mounting part 902, and the other end can be snapped into the other of the first mounting part 901 and the second mounting part 902 to achieve pre-installation of the electric auxiliary heater 130. When the installer performs the screwing operation to fasten the electric auxiliary heater 130 to the first mounting part 901 and / or the second mounting part 902, there is no need to hold the electric auxiliary heater 130 with hands, and no complicated installation steps or additional fasteners are required, thereby simplifying the installation process and improving assembly efficiency.

[0067] Figure 3 for Figure 1 The enlarged diagram of point B in the middle. Figure 1 and Figure 3In some embodiments, to facilitate assembly of the impeller 30, the air conditioner further includes a second volute 100. The second volute 100 is detachably connected to the first volute 20. When installing the impeller 30, the impeller 30 is installed in the first volute 20, and then the second volute 100 is installed on the first volute 20. When inspecting the impeller 30, the second volute 100 can be removed from the first volute 20, and the impeller 30 can be removed from the first volute 20 for inspection. When the air conditioner is in use, the first volute 20 is located above the second volute 100.

[0068] Combine Figure 3 and Figure 5 In some embodiments, in order to ensure that the second volute 100 is accurately installed on the first volute 20, one of the first volute 20 and the second volute 100 is provided with a limiting member, and the other has a limiting groove 201. The limiting member can be embedded in the limiting groove 201 to limit the second volute 100, thereby ensuring that the second volute 100 will not deviate from the predetermined position and angle during the installation process, reducing errors in the installation process, and improving installation accuracy, so that the second volute 100 can be installed in place at one time without the need for multiple adjustments and corrections after installation, thereby saving installation time and improving work efficiency. Moreover, after the limiting member is embedded in the limiting groove 201, the limiting member conflicts with the groove wall of the limiting groove 201, which can reduce displacement or loosening caused by vibration or external force, and ensure the stability of the installation of the second volute 100.

[0069] Combine Figure 3 and Figure 5 In some embodiments, in order to achieve a detachable connection between the second volute 100 and the first volute 20, one of the first volute 20 and the second volute 100 is provided with a second clip 202, and the other is provided with a slot 1001, and the second clip 202 is clamped in the slot 1001. When the second volute 100 is connected to the first volute 20, the second clip 202 is clamped in the slot 1001. At the same time, the second volute 100 can be limited on the first volute 20, further ensuring the accuracy of the installation position of the second volute 100. When the second volute 100 is separated from the first volute 20, the second clip 202 is separated from the slot 1001 to facilitate the disassembly and assembly of the second volute 100 and the first volute 20.

[0070] In some embodiments, the first volute 20 may be provided with a second buckle 202, and the second volute 100 may be provided with a slot 1001. Of course, in other embodiments, the second volute 100 may be provided with a second buckle 202, and the second volute 100 may be provided with a slot 1001.

[0071] In some embodiments, when the second buckle 202 is provided on the first volute 20 , the second buckle 202 is integrally formed with the first volute 20 ; when the second buckle 202 is provided on the second volute 100 , the second buckle 202 is integrally formed with the second volute 100 .

[0072] Combine Figure 3 and Figure 5 In some embodiments, a first reserved mounting portion 203 is provided on the first volute 20, and a second reserved mounting portion 1002 is provided on the second volute 100. When the second buckle 202 breaks, a locking member can be used to connect the first reserved mounting portion 203 and the second reserved mounting portion 1002 to fasten the second volute 100 to the first volute 20, providing a remedial measure. The locking member can be a bolt, a screw, or a connecting pin.

[0073] In some embodiments, the first volute 20 and the first reserved installation portion 203 may be integrally formed by injection molding, and the second volute 100 and the second reserved installation portion 1002 may be integrally formed by injection molding.

[0074] Figure 9 for Figure 1 Schematic diagram of the cooperation between the first volute and the second volute. Figure 9 In some embodiments, in order to ensure sealing, a stopper 202 is provided at the end of the first volute 20 facing the middle partition 10, and the edge of the second volute 100 can be embedded in the stopper 202. The stopper 202 is tightly fitted with the edge of the second volute 100 to form an effective sealing interface, which can significantly reduce or prevent gas leakage between the first volute 20 and the second volute 100, thereby improving the sealing performance. Moreover, through the stopper fitting method, the first volute 20 and the second volute 100 are structurally supported and fixed to each other, which not only enhances the overall rigidity of the volute assembly, but also helps to reduce deformation and damage caused by vibration or impact, thereby improving the operating stability and reliability of the equipment. At the same time, by embedding the edge of the second volute 100 in the stopper 202, the positioning of the second volute 100 can be achieved, so as to facilitate the disassembly and assembly of the second volute 100, reduce maintenance costs and time, and improve the maintainability of the equipment.

[0075] Combine Figure 1 and Figure 2In some embodiments, to ensure the stability of the installation of the side panels 1101, the air conditioner further includes a housing 110, which includes side panels 1101. The side panels 1101 are connected to the intermediate partition 10 and the bearing bracket 60. The intermediate partition 10 and the bearing bracket 60 jointly support the side panels 1101, firmly securing the side panels 1101 and effectively dispersing the forces they bear. This enhances the overall strength and stability of the structure, helps reduce deformation or damage caused by vibration, impact, or pressure changes, and improves the reliability and durability of the equipment.

[0076] Combine Figure 4 and Figure 5 In some embodiments, in order to ensure the cooling or heating efficiency of the air conditioner, an air vent 101 is opened on the middle partition 10, and the air vent 101 is connected to the first volute 20. When the impeller 30 rotates, the air discharged from the first volute 20 can reach the heat exchanger through the air vent 101 to achieve heat exchange.

[0077] In some embodiments, the cross-sectional area of ​​the air outlet 101 gradually increases along the air outlet direction, that is, the air outlet 101 is trumpet-shaped to achieve diffuse air outlet, which can reduce the air flow resistance, make the air flow smooth, and ensure smooth air outlet. Moreover, according to the mold flow analysis results, in order to achieve the gradual increase in the cross-sectional area of ​​the air outlet 101, when designing and preparing the mold of the middle partition 10, the mold is designed with pre-deformation, and the deformation is highly adjustable, which reduces the difficulty of injection molding machine adjustment and improves the qualified rate of finished products. At the same time, since the air outlet 101 is trumpet-shaped, it can more effectively resist lateral pressure and bending moment, thereby enhancing the stability of the middle partition 10, and can better resist fatigue damage caused by cyclic loads and vibrations, which helps to disperse and alleviate stress fluctuations caused by cyclic loads, thereby extending the service life of the middle partition 10.

[0078] Figure 7 for Figure 4 Top view of the middle partition; Figure 8 for Figure 7 CC section view of the middle partition. Figure 3 、 Figure 7 and Figure 8 In some embodiments, in order to support the bearing 70, an embedding groove is provided on the circumferential surface of the bearing 70, and the bearing bracket 60 includes: a connecting portion 601, a first limiting portion 603 and a second limiting portion 604. The connecting portion 601 is provided with a mounting hole 602 and is integrally formed with the intermediate partition 10. The first limiting portion 603 is provided in the mounting hole 602 and can be embedded in the embedding groove. The second limiting portion 604 is located at the end of the mounting hole 602 away from the support frame 40 and can conflict with the end of the bearing 70, wherein the connecting portion 601, the first limiting portion 602, the second limiting portion 603 and the intermediate partition 10 are integrally formed by injection molding. The first limiting portion 603 can be annular.

[0079] In some embodiments, when the bearing 70 is to be installed, the bearing 70 is installed in the mounting hole 602 along the direction of the support frame 40 toward the bearing bracket 60, and the bearing 70 is pushed toward the inside of the mounting hole 602 along the axial direction of the mounting hole 602 until the first limiting portion 603 is embedded in the embedding groove to ensure that the bearing 70 is installed in place. At the same time, the second limiting portion 604 conflicts with the end of the bearing 70 to limit the bearing 70, avoid excessive installation of the bearing 70, and further ensure the accurate installation position of the bearing 70.

[0080] In some embodiments, in order to facilitate the first limiting portion 603 to be embedded in the embedding groove, the end of the first limiting portion 603 facing the support frame 40 has a slope, that is, along the hole wall of the mounting hole 602 toward the center of the mounting hole 602, the thickness of the first limiting portion 603 gradually decreases, and can be guided by the slope so that the first limiting portion 603 can automatically align and slide in smoothly when approaching the embedding groove, which simplifies the installation process, reduces the requirements for installation accuracy, reduces the difficulty of installation, and reduces damage or failure caused by improper installation. Since the installation process is simplified, the installation time is shortened, thereby improving the installation efficiency.

[0081] Combine Figure 3 In some embodiments, to further limit the position of the bearing 70, the air conditioner further includes a sealing plate 120. The sealing plate 120 is detachably connected to the connecting portion 601. The sealing plate 120 and the second limiting portion 604 are respectively located at opposite ends of the mounting hole 602. Along the axial direction of the rotating shaft 80, the projection of the sealing plate 120 on the connecting portion 601 at least partially overlaps with the projection of the mounting hole 602 on the connecting portion 601. The sealing plate 120 defines a through hole 1201, which is coaxial with the bearing 70 and the mounting hole 602.

[0082] In some embodiments, after the bearing 70 is installed in the mounting hole 602, the sealing plate 120 is connected to the connecting portion 601. Through the coordinated action of the sealing plate 120 and the second limiting portion 604, the bearing 70 is limited along the axial direction of the mounting hole 602, thereby preventing the bearing 70 from falling out of the mounting hole 602 and ensuring the stability of the installation of the bearing 70.

[0083] Combine Figure 3 、 Figure 7 and Figure 8In some embodiments, to accurately position the sealing plate 120 on the connecting portion 601, two slide grooves 606 are provided on the connecting portion 601, with the mounting hole 602 located between the two slide grooves 606. The sealing plate 120 is slidably disposed within the slide grooves 606 and can abut against the bottom wall of the slide grooves 606. The two slide grooves 606 limit the sealing plate 120 in the radial direction of the mounting hole 602 to ensure that the sealing plate 120 is properly installed. The two slide grooves 606 are arranged in parallel, and each end of the slide grooves 606 has an opening through which the sealing plate 120 can enter the slide grooves 606.

[0084] Combine Figure 3 、 Figure 7 and Figure 8 In some embodiments, the connection portion 601 is provided with a blocking portion 607, which is located at the bottom of the chute 606 and is arranged opposite to the opening. In other words, the blocking portion 607 is the bottom wall of the chute 606. The sealing plate 120 slides in the chute 606 until it conflicts with the blocking portion 607. The blocking portion 607 limits the position of the sealing plate 120 to ensure that the sealing plate 120 is installed in place. At the same time, it also prevents the sealing plate 120 from falling out of the chute 606, further ensuring the stability of the connection between the sealing plate 120 and the connection portion 601. The blocking portion 607 can be located at the bottom of the chute 606, and the opening can be located at the top of the chute 606.

[0085] Combine Figure 3 、 Figure 7 and Figure 8 In some embodiments, to ensure the stability of the sealing plate installation, the bearing bracket 60 further includes a first clip 605. The first clip 605 is integrally formed with the connecting portion 601 by injection molding and is located between the two slide grooves 604. The first clip 605 is disposed opposite the bottom wall of the slide groove 604, wherein the sealing plate 120 can be locked in the first clip 605.

[0086] In some embodiments, when the sealing plate 120 slides in the slide groove 606 and conflicts with the bottom wall of the slide groove 606, the sealing plate 120 is clamped in the first clip 605, and the sealing plate 120 is limited in the axial direction of the mounting hole 602 by the first clip 605 to ensure that the sealing plate 120 is installed in place. At the same time, it can prevent the sealing plate 120 from falling off from the slide groove 606, thereby ensuring the stability of the installation of the sealing plate 120.

[0087] Because the outer ring of the bearing 70 is made of rubber, when the rotating shaft 80 is connected to the bearing 70, the rotating shaft 80 may conflict with the rubber, causing damage to the rubber. In some embodiments, to ensure the safety of the bearing 70, the sealing plate 120 is provided with a through hole 1201. The through hole 1201 is coaxial with the bearing 70 and the mounting hole 602. Along the axial direction of the through hole 1201, the projection of the sealing plate 120 on the bearing 70 at least partially overlaps with the outer ring of the bearing 70, so that the sealing plate 120 can completely cover the outer ring of the bearing 70. When the rotating shaft 80 is connected to the bearing 70, the rotating shaft 80 passing through the through hole 1201 can be directly connected to the inner ring of the bearing 70, ensuring the accurate installation position of the rotating shaft 70, avoiding conflict between the rotating shaft 80 and the outer ring of the bearing 70, and ensuring the safety of the bearing 70.
