In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples.

In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0046] The air conditioner 100 according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0047] like Figures 1 to 12As shown, the air conditioner 100 according to the embodiment of the utility model comprises: a fan component 10 and a chassis assembly 20, the fan component 10 comprises a wind wheel 1 and a motor 2, wherein the output shaft of the motor 2 is connected to the wind wheel 1, so that the wind wheel 1 can be driven to rotate by the motor 2 to drive the gas flow to realize air circulation. The fan component 10 is arranged on the chassis assembly 20, and the chassis assembly 20 comprises a chassis 3 and a motor mounting structure 4, the chassis 3 is formed with an air duct, the wind wheel 1 is arranged in the air duct, the motor mounting structure 4 is arranged on the chassis 3 and is located on one side of the air duct, and the motor mounting structure 4 comprises: a motor cover 5 and a motor fixing plate, the motor cover 5 is arranged on the chassis 3 and defines an installation space with the chassis 3, the motor 2 is arranged in the installation space, and the motor fixing plate is arranged on a side of the installation space away from the wind wheel 1 and is used to fix the motor 2.

[0048] That is to say, the motor cover 5 and the chassis 3 can jointly define an installation space extending along the axial direction of the motor 2, so that the portion of the installation space defined by the motor cover 5 and the chassis 3 can better limit the freedom of movement of the motor 2 in the radial and circumferential directions, and the motor fixing plate can better prevent the motor 2 from moving in the installation space in a direction away from the wind wheel 1, so that the motor fixing plate can better limit the freedom of movement of the motor 2 in the axial direction. Therefore, the motor mounting structure 4 can limit the freedom of movement of the motor 2 in the radial, axial and circumferential directions through the cooperation with the chassis 3, and the fixing effect and protection effect of the motor mounting structure 4 on the motor 2 can be guaranteed, so that the motor 2 can be better prevented from having a positional deviation that affects the stability of the airflow conveyed by the fan component 10.

[0049] The motor fixing plate includes a first pressing plate 6 and a second pressing plate 7 that are detachably connected, the first pressing plate 6 is detachably connected to the motor cover 5, and the second pressing plate 7 is detachably connected to the chassis 3. Therefore, by dividing the motor fixing plate into the first pressing plate 6 and the second pressing plate 7 that are detachably connected, the flexibility of the motor fixing plate installation can be improved to meet the requirements of different installation processes.

[0050] For example, during the assembly process of the chassis assembly 20, before installing the motor cover 5 and the first pressure plate 6, since the second pressure plate 7 is detachably connected to the chassis 3, the second pressure plate 7 can be fixed on the chassis 3 first. Since the second pressure plate 7 is located on the side of the installation space away from the wind wheel 1 in the axial direction of the motor 2, the second pressure plate 7 can form an axial limit for the motor 2. At this time, the motor cover 5 and the first pressure plate 6 have not been installed yet, which makes it convenient to place the motor 2 on the side of the second pressure plate 7 facing the wind wheel 1, which helps to reduce the difficulty of installing the motor 2 to the chassis assembly 20. Then, the motor cover 5 and the first pressure plate 6 can be installed on the chassis 3 to form a complete motor mounting structure 4 with the second pressure plate 7 on the chassis 3.

[0051] Furthermore, the detachable connection between the second pressing plate 7 and the chassis 3 can realize the detachable connection between the motor fixing plate and the chassis 3, and the detachable connection between the first pressing plate 6 and the motor cover 5 can realize the detachable connection between the motor fixing plate and the motor cover 5, thereby realizing the detachable connection between the motor fixing plate and the motor cover 5 and the chassis 3. Therefore, when it is necessary to perform maintenance operations such as overhaul on the motor 2, the motor fixing plate can be removed from the motor cover 5 and the chassis 3, thereby opening the opening of the installation space on the side of the motor 2 away from the wind wheel 1 in the axial direction, so as to take the motor 2 out of the installation space for overhaul and other maintenance operations.

[0052] In addition, the motor mounting structure 4 can be formed into an integral structure by connecting the first pressure plate 6 to the motor cover 5 and the second pressure plate 7 respectively. As a result, the motor cover 5 is connected to the chassis 3 through the first pressure plate 6 and the second pressure plate 7 on the basis of being arranged on the chassis 3. The first pressure plate 6 is connected to the chassis 3 through the motor cover 5 and to the chassis 3 through the second pressure plate 7. The second pressure plate 7 is connected to the chassis 3 through the first pressure plate 6 and the motor cover 5 on the basis of being directly connected to the chassis 3. This can improve the stability of the connection between the motor cover 5, the first pressure plate 6 and the second pressure plate 7 and the chassis 3, thereby improving the structural stability of the motor mounting structure 4 after installation, which is beneficial to improving the fixing effect of the motor mounting structure 4 on the motor 2.

[0053] According to the air conditioner 100 of the embodiment of the utility model, by dividing the motor fixing plate into a detachably connected first pressure plate 6 and a second pressure plate 7, the flexibility of the installation of the motor fixing plate can be improved, and the motor fixing plate can be removed from the motor cover 5 and the chassis 3 to facilitate the motor 2 to be taken out of the installation space for inspection and other maintenance operations. At the same time, the structural stability of the motor mounting structure 4 after installation can be improved, which is conducive to improving the fixing effect of the motor mounting structure 4 on the motor 2.

[0054] According to some embodiments of the utility model, the chassis 3 includes a wind wheel mounting portion 31 and a motor mounting portion 32 arranged along the axial direction of the motor 2, the wind wheel 1 is rotatably disposed on the wind wheel mounting portion 31, and the motor 2 is mounted on the motor mounting portion 32, so that the wind wheel mounting portion 31 can be used as a position marker when the wind wheel 1 is installed on the chassis 3, and the motor mounting portion 32 can be used as a position marker when the motor 2 and the motor mounting structure 4 are installed on the chassis 3, thereby effectively reducing the difficulty of positioning the fan component 10 and the motor mounting structure 4 when they are installed on the chassis 3, which is beneficial to improving the efficiency of installing the fan component 10 and the motor mounting structure 4 on the chassis 3.

[0055] Among them, the motor cover 5 and the motor mounting portion 32 are arranged relative to each other along the first direction e1 and jointly define an installation space, the first direction e1 is perpendicular to the axial direction of the motor 2, and the first pressing plate 6 and the second pressing plate 7 are arranged along the first direction e1. That is to say, the arrangement direction of the first pressing plate 6 and the second pressing plate 7 is consistent with the arrangement direction of the motor cover 5 and the motor mounting portion 32. After the second pressing plate 7 is connected to the chassis 3, the assembly direction of the first pressing plate 6 to the second pressing plate 7 is consistent with the assembly direction of the motor cover 5 to the chassis 3. As a result, the assembly flexibility of the motor cover 5 and the first pressing plate 6 can be well improved. Specifically, the motor cover 5 and the first pressing plate 6 can be installed separately, such as installing the motor cover 5 first and then installing the first pressing plate 6. It is also possible to connect the motor cover 5 to the first pressing plate 6 and then install the combined structure of the motor cover 5 and the first pressing plate 6 on the chassis 3 to improve the assembly efficiency of the air conditioner 100 in the final assembly process.

[0056] In a specific example, a motor baffle is formed on the chassis, and the motor baffle and the second pressure plate 7 are opposite to each other along the axial direction of the motor 2 and are spaced apart to limit the axial movement of the motor 2. The motor baffle is located on the side of the wind wheel facing the second pressure plate 7, and a first positioning groove open toward the motor cover 5 is formed on the motor baffle, and a second positioning groove open toward the motor baffle is formed on the portion of the motor cover 5 opposite to the motor baffle along the first direction e1, and the first positioning groove and the second positioning groove together constitute a first positioning hole, and the first positioning hole is used to position the positioning boss of the motor 2 on the side facing the wind wheel 1 in the axial direction; in the first direction e1, a third positioning groove open toward the second pressure plate 7 is formed on the side of the first pressure plate 6 facing the second pressure plate 7, and a fourth positioning groove open toward the first pressure plate 6 is formed on the side of the second pressure plate 7 facing the first pressure plate 6, and the third positioning groove and the fourth positioning groove together constitute the second positioning hole, and the second positioning hole is used to position the positioning boss of the motor 2 on the side away from the wind wheel in the axial direction.

[0057] In some embodiments, the motor cover 5 is detachably connected to the chassis 3. Specifically, one end of the motor cover 5 in the second direction e2 is plugged and matched with the chassis 3, such as a plug-in protrusion is formed on the motor cover 5, and a plug-in groove is formed on the chassis 3, so that the motor cover 5 is pre-positioned and limited by the plug-in protrusion and the plug-in groove, and the other end of the motor cover 5 in the second direction e2 is connected to the chassis 3 by a fastener, such as a connecting ear is formed on the other end of the motor cover 5, and a mounting hole is formed on the connecting ear, and a fixing hole corresponding to the mounting hole is formed on the chassis 3, and the fastener can be fixed to the chassis 3 by passing through the mounting hole and the fixing hole.

[0058] According to some embodiments of the utility model, the first pressing plate 6 is connected to the motor cover 5 by snapping. The snap-on connection structure is easy to operate, and does not require the use of additional fasteners for connection. At the same time, it is not necessary to use tools to match and separate the snap-on connection structure. For example, the operator can directly match and separate the snap-on connection structure by hand. As a result, the difficulty of assembling and separating the first pressing plate 6 and the motor cover 5 can be reduced, so that the first pressing plate 6 can be easily removed from the motor cover 5 to facilitate the maintenance of the motor 2 while improving the assembly efficiency of the first pressing plate 6 and the motor cover 5. In addition, the cost of connecting the first pressing plate 6 to the motor cover 5 can be reduced.

[0059] According to some embodiments of the utility model, the motor cover 5 and the first pressing plate 6 cooperate with each other through the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure to form a limit on the first pressing plate 6. That is to say, the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure are all used to limit the freedom of movement of the first pressing plate 6 relative to the motor cover 5, and there are at least four matching positions of the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure between the first pressing plate 6 and the motor cover 5. As a result, the matching position between the motor cover 5 and the first pressing plate 6 can be increased well, so that the limiting effect on the freedom of movement of the first pressing plate 6 can be improved to avoid the first pressing plate 6 from swinging relative to the motor cover 5. As a result, the stability of the connection between the first pressing plate 6 and the motor cover 5 can be improved, so that the stability of the motor mounting structure 4 can be improved to improve the fixing effect of the motor mounting structure 4 on the motor 2.

[0060] In a specific example, the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure cooperate together to achieve six-way limiting of the first pressure plate 6, thereby preventing the first pressure plate 6 from moving in any direction relative to the motor cover 5, which is beneficial to improving the connection stability between the first pressure plate 6 and the motor cover 5.

[0061] According to some embodiments of the utility model, the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure are arranged along the circumference of the motor 2. That is to say, the first pressure plate 6 and the motor cover 5 can be matched at four different positions on the circumference of the motor 2 through the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure, so that the first pressure plate 6 can be limited at multiple different positions on the circumference of the motor 2, which is conducive to improving the limiting effect of the first pressure plate 6. In addition, the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure are arranged along the circumference of the motor 2, which can better avoid the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure from interfering with each other when the first pressure plate 6 is connected to the motor cover 5, thereby reducing the difficulty of assembling and disassembling the first pressure plate 6 and the motor cover 5.

[0062] In a specific example, the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure are arranged in sequence along the circumferential direction of the motor 2 .

[0063] According to some embodiments of the utility model, the first limiting structure includes a first limiting groove 511 formed on the motor cover 5 and a first limiting protrusion 611 formed on the first pressure plate 6, and the first limiting protrusion 611 is located in the first limiting groove 511 to limit the first pressure plate 6 in the axial direction and the circumferential direction of the motor 2. In other words, through the cooperation of the first limiting protrusion 611 and the first limiting groove 511, the freedom of movement of the first pressure plate 6 relative to the motor cover 5 can be limited in the axial direction and the circumferential direction of the motor 2. In addition, the first limiting groove 511 and the first limiting protrusion 611 are plug-in matched, and the matching method is simple and easy to operate.

[0064] The second limiting structure includes a second limiting protrusion 512 formed on the motor cover 5 and a limiting hole 612 formed on the first pressing plate 6, and the second limiting protrusion 512 is inserted into the limiting hole 612 to limit the first pressing plate 6 in the circumferential direction of the motor 2. In other words, through the cooperation of the second limiting protrusion 512 and the limiting hole 612, the freedom of movement of the first pressing plate 6 relative to the motor cover 5 in the circumferential direction of the motor 2 can be limited, thereby improving the limiting effect of the freedom of movement of the first pressing plate 6 in the circumferential direction of the motor 2 on the basis of the first limiting structure. In addition, the second limiting protrusion 512 and the limiting hole 612 are plug-in matched, and the matching method is simple and easy to operate.

[0065] The third limiting structure includes a first spring buckle 513 formed on the motor cover 5 and a matching through hole 613 formed on the first pressure plate 6. The first spring buckle 513 includes a first elastic arm and a first protrusion provided on the first elastic arm. The first elastic arm is provided in the matching through hole 613. The first protrusion is located on the side of the first pressure plate 6 away from the second pressure plate 7 in the first direction e1 and abuts against the first pressure plate 6 along the first direction e1 to form a limit on the first pressure plate 6 in the first direction e1. In other words, the abutment of the first protrusion with the first pressure plate 6 can better limit the movement in the direction away from the second pressure plate 7 along the first direction e1, so as to limit the freedom of movement of the first pressure plate 6 relative to the motor cover 5 in the first direction e1. In addition, the first spring buckle 513 is plug-fitted with the matching through hole 613 and elastically snap-fitted with the first pressure plate 6. The matching method is simple and easy to operate.

[0066] The fourth limiting structure includes a third limiting protrusion 514 formed on the motor cover 5 and a second limiting groove 614 formed on the first pressing plate 6. The third limiting protrusion 514 is located in the second limiting groove 614 to limit the first pressing plate 6 in the circumferential direction of the motor 2 and in the first direction e1. In other words, through the cooperation of the third limiting protrusion 514 and the second limiting groove 614, the freedom of movement of the first pressing plate 6 relative to the motor cover 5 can be limited in the circumferential direction of the motor 2 and in the first direction e1. In addition, the third limiting protrusion 514 and the second limiting groove 614 are plug-in matched, and the matching method is simple and easy to operate.

[0067] Thus, through the cooperation of the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure, the freedom of movement of the first pressing plate 6 relative to the motor cover 5 can be limited in the circumferential direction, axial direction and first direction e1 of the motor 2, that is, the first pressing plate 6 can be prevented from moving relative to the motor cover 5 in the circumferential direction, axial direction and first direction e1 of the motor 2, such as realizing six-way limiting of the first pressing plate 6, which is conducive to improving the stability of the connection between the first pressing plate 6 and the motor cover 5. In addition, the cooperation methods of the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure are relatively simple, thereby reducing the difficulty of assembling and disassembling the first pressing plate 6 and the motor cover 5.

[0068] According to some embodiments of the utility model, the motor cover 5 and the first pressure plate 6 are also matched through a fifth limiting structure, and the fifth limiting structure is located between the first limiting structure and the second limiting structure in the circumferential direction of the motor 2. The fifth limiting structure includes a third limiting groove 515 formed on the motor cover 5 and a second spring buckle 615 formed on the first pressure plate 6. The third limiting groove 515 is U-shaped and open toward the second pressure plate 7 along the first direction e1, and the second spring buckle 615 is snap-fitted with the third limiting groove 515 along the first direction e1. That is to say, after the first pressure plate 6 and the motor cover 5 are assembled, at least a part of the second spring buckle 615 is located in the third limiting groove 515. The cooperation between the second spring buckle 615 and the third limiting groove 515 can better prevent the second spring buckle 615 from moving relative to the third limiting groove 515 along the first direction e1 toward the direction away from the second cover plate, thereby better limiting the movement of the first pressure plate 6 relative to the motor cover 5 in the first direction e1, that is, the fifth limiting structure is used to limit the movement of the first pressure plate 6 relative to the motor cover 5 in the first direction e1.

[0069] Thus, the cooperation between the second spring buckle 615 and the third limiting groove 515 can further limit the freedom of movement of the first pressing plate 6 relative to the motor cover 5 in the first direction e1 on the basis of the third limiting structure and the fourth limiting structure, thereby further improving the connection stability between the first pressing plate 6 and the motor cover 5, which is beneficial to improving the structural stability of the motor mounting structure 4. In addition, the second spring buckle 615 and the third limiting groove 515 are engaged in a simple manner and easy to operate.

[0070] According to some embodiments of the utility model, in the axial direction of the motor 2, one end of the motor cover 5 adjacent to the first pressure plate 6 is formed as a first matching portion 51 that matches the first pressure plate 6, and the first limiting groove 511, the second limiting protrusion 512, the first spring buckle 513 and the third limiting protrusion 514 are arranged along the circumferential direction of the motor 2 on the side of the first matching portion 51 facing the first pressure plate 6, the first limiting groove 511 is located at one end of the first matching portion 51 in the circumferential direction of the motor 2, and the first matching portion 51 The other end face away from the first limiting groove 511 in the circumferential direction of the motor 2 constitutes an anti-dropping buckle surface 516, and an anti-dropping buckle 616 is also formed on the first pressure plate 6. In the circumferential direction of the motor 2, the anti-dropping buckle 616 is located on the side of the second limiting groove 614 away from the matching through hole 613, and the anti-dropping buckle 616 extends along the axial direction of the motor 2 toward the direction close to the wind wheel 1 and is clamped on the anti-dropping buckle surface 516 to form a limit for the first pressure plate 6 in the circumferential direction of the motor 2 and in the first direction e1.

[0071] That is to say, through the cooperation of the anti-drop buckle surface 516 and the anti-drop buckle 616, the anti-drop buckle 616 can be well blocked from moving in the direction close to the first limiting groove 511 along the circumference of the motor 2, and at the same time, the anti-drop buckle 616 can be blocked from moving in the direction away from the second pressing plate 7 along the first direction e1, so that the freedom of movement of the first pressing plate 6 in the circumference of the motor 2 and in the first direction e1 relative to the motor cover 5 can be well limited. Therefore, through the cooperation of the anti-drop buckle surface 516 and the anti-drop buckle 616, the freedom of movement of the first pressing plate 6 in the circumference of the motor 2 and in the first direction e1 relative to the motor cover 5 can be further limited on the basis of the first limiting structure, the second limiting structure, the third limiting structure and the fourth limiting structure, so that the connection stability of the first pressing plate 6 and the motor cover 5 can be further improved, which is conducive to improving the structural stability of the motor mounting structure 4. In addition, the anti-drop buckle 616 is engaged with the anti-drop buckle surface 516, and the cooperation method is simple and easy to operate.

[0072] In some embodiments, the first pressing plate 6 is provided with a first connecting lug 63 connected to the chassis 3, and the anti-drop buckle 616 and the first connecting lug 63 are located on the same side of the first pressing plate 6 in the second direction e2. Therefore, when the combined structure of the first pressing plate 6 and the motor cover 5 is installed on the combined structure of the chassis 3 and the second pressing plate 7, the anti-drop buckle 616 cooperates with the anti-drop buckle surface 516 to better avoid the risk of the first pressing plate 6 falling off the motor cover 5 when the first connecting lug 63 is subjected to external force during transportation or installation of the combined structure of the first pressing plate 6 and the motor cover 5, thereby ensuring the firm connection between the first pressing plate 6 and the motor cover 5.

[0073] In a specific example, in the axial direction of the motor 2, a first matching portion 51 is formed at one end of the motor cover 5 facing the first pressure plate 6, and the side of the first matching portion 51 away from the wind wheel 1 is formed as a mounting surface 51a, and the first limiting groove 511, the third limiting groove 515, the second limiting protrusion 512, the first spring buckle 513 and the third limiting protrusion 514 are arranged on the mounting surface 51a at intervals along the circumference of the motor 2, the first limiting groove 511 is located at one end of the first matching portion 51 in the circumferential direction of the motor 2, and the anti-detachment buckle surface 516 is the end surface of the other end of the first matching portion 51 in the circumferential direction of the motor 2, and the end of the first pressure plate 6 away from the second pressure plate 7 in the first direction e1 is formed as a second matching portion 61, and the first limiting protrusion 611, the second spring buckle 615, the limiting hole 612, the matching through hole 613, the second limiting groove 614 and the anti-detachment buckle 616 are arranged on the second matching portion 61 at intervals along the circumference of the motor 2.

[0074] Specifically, the first limiting groove 511 includes a first limiting portion arranged opposite to the mounting surface 51a, and a second limiting portion and a third limiting portion connected between the mounting surface 51a and the first limiting portion. The second limiting portion is located on the side of the first limiting protrusion 611 that is away from the limiting hole 612 in the circumferential direction of the motor 2, and the third limiting portion is located on the side of the second limiting portion toward the first limiting protrusion 611 and on the side of the first limiting protrusion 611 toward the second pressure plate 7 in the first direction e1, so that the first limiting protrusion 611 is limited by the first limiting portion and the mounting surface 51a to form a limitation on the axial direction of the motor 2, and the first limiting protrusion 611 is limited by the second limiting portion to limit the movement of the first pressure plate 6 along the circumferential direction of the motor 2 toward the direction away from the anti-dropping buckle surface 516, and at the same time, the first limiting protrusion 611 is limited by the third limiting portion to limit the movement of the first pressure plate 6 along the first direction e1 toward the direction close to the second pressure plate 7.

[0075] Among them, the second limiting protrusion 512 is arranged at intervals with the mounting surface 51a, and in the circumferential direction of the motor 2, the opposite side surfaces of the second limiting protrusion 512 are respectively abutted with the opposite side surfaces of the limiting hole 612, so that the movement of the first pressing plate 6 relative to the motor cover 5 in the circumferential direction of the motor 2 can be well limited by the plug-in cooperation of the second limiting protrusion 512 and the limiting hole 612. In addition, in the direction from the second pressing plate 7 to the first pressing plate 6, the opposite side surfaces of the second limiting protrusion 512 in the circumferential direction of the motor 2 and the opposite side surfaces of the limiting hole 612 in the circumferential direction of the motor 2 are inclined and extended in a direction close to each other. Therefore, in the assembly process of the first pressing plate 6 and the motor cover 5, the cooperation of the second limiting protrusion 512 and the limiting hole 612 can form a guide structure to guide the first pressing plate 6 and the motor cover 5 to be installed in the correct direction, which is conducive to reducing the difficulty of assembling the first pressing plate 6 and the motor cover 5.

[0076] Among them, the first spring buckle 513 is spaced apart from the mounting surface 51a and includes a first elastic arm and a first protrusion. The first protrusion is located on the side of the first elastic arm away from the mounting surface 51a in the axial direction of the motor 2. The first elastic arm is penetrated into the matching through hole 613. The first protrusion abuts against the side of the first matching portion 51 away from the second pressure plate 7 in the first direction e1, so that the first spring buckle 513 can better limit the movement of the first pressure plate 6 along the first direction e1 toward the direction away from the second pressure plate 7.

[0077] The third limiting protrusion 514 is spaced from the mounting surface 51a, the second limiting groove 614 includes a fourth limiting portion located between the third limiting protrusion 514 and the mounting surface 51a and a fifth limiting portion located on the side of the third limiting protrusion 514 away from the second pressing plate 7 in the first direction e1, the side of the third limiting protrusion 514 facing the mounting surface 51a abuts against the side of the fourth limiting portion away from the mounting surface 51a, and in the first direction e1, one end of the third limiting protrusion 514 away from the second pressing plate 7 abuts against the side of the fifth limiting portion facing the second pressing plate 7. Thus, the abutment between the third limiting protrusion 514 and the fourth limiting portion can better limit the first pressing plate 6 from moving in the axial direction of the motor 2 toward the direction away from the wind wheel 1, and the abutment between the third limiting protrusion 514 and the fifth limiting portion can better limit the first pressing plate 6 from moving in the first direction e1 toward the second pressing plate 7.

[0078] According to some embodiments of the utility model, in the axial direction of the motor 2, one end of the first pressure plate 6 adjacent to the motor cover 5 is formed as a second matching portion 61 that matches the motor cover 5, the first limiting protrusion 611, the limiting hole 612, the matching through hole 613 and the second limiting groove 614 are all formed on the second matching portion 61, and the outer surface of the second matching portion 61 is formed with a first indication mark 621 and a second indication mark 622, the first indication mark 621 is formed as a convex rib indicating the matching direction of the first limiting protrusion 611 and the first limiting groove 511, and the second indication mark 622 is formed as a convex rib indicating the disassembly direction of the first pressure plate 6. The outer side surface of the second matching portion 61 here refers to the side surface of the second matching portion 61 away from the second pressure plate 7 in the first direction e1.

[0079] Thus, by providing the first indicator mark 621 and the second indicator mark 622, it is convenient for the operator to install the first pressing plate 6 according to the first indicator mark 621 or to disassemble the first pressing plate 6 according to the second indicator mark 622, which helps to reduce the difficulty of assembling and disassembling the first pressing plate 6. In addition, the first indicator mark 621 and the second indicator mark 622 are both located on the outer side of the second matching portion 61, making the first indicator mark 621 and the second indicator mark 622 more intuitive, thereby reducing the difficulty of discovering the first indicator mark 621 and the second indicator mark 622.

[0080] In a specific example, on the circumference of the motor 2, the first indicator mark 621 is located between the limiting hole 612 and the first limiting protrusion 611, and the first indicator mark 621 is formed as an arrow-shaped rib pointing from the limiting hole 612 to the first limiting protrusion 611, and the second indicator mark 622 is located on the side of the matching through hole 613 away from the limiting hole 612 on the circumference of the motor 2, and the second indicator mark 622 is formed as a plurality of dot-shaped ribs arranged in a triangle.

That is, the first pressing plate 6 is fixed on the chassis 3 through the connection between the first connecting lug 63 and the chassis 3, that is, the first pressing plate 6 is directly connected to the chassis 3 through a fastener on the basis of being connected to the chassis 3 through the second pressing plate 7 and the motor cover 5, so that the stability of the first pressing plate 6 after installation can be further improved. In addition, by providing the first connecting lug 63, a larger installation space can be provided for the connection of the fastener, and the influence of the opening on the main structure of the first pressing plate 6 can be better avoided.

In the description herein, the fastener can be a detachable fastener such as a plastic buckle, a screw, etc., and the specific type of the fastener is not specifically limited here.

[0082] According to some embodiments of the utility model, a second connecting lug 71 is formed on the second pressing plate 7 and is stacked with the first connecting lug 63 along the first direction e1, and a fastener is simultaneously passed through the first connecting lug 63, the second connecting lug 71 and the chassis 3. In other words, by providing the first connecting lug 63 and the second connecting lug 71, the first pressing plate 6 and the second pressing plate 7 can be fixed to the chassis 3 by the same fastener. In this way, the number of fasteners and the installation process can be well saved, and at the same time, the number of holes on the chassis 3 for fixing the first connecting lug 63 and the second connecting lug 71 can be reduced, which is conducive to simplifying the connection structure and improving the assembly efficiency.

[0083] According to some embodiments of the utility model, one end of the first pressing plate 6 in the second direction e2 is plugged with the second pressing plate 7, and the other end of the first pressing plate 6 in the second direction e2 is connected to the second pressing plate 7 by a fastener, and the second direction e2 is perpendicular to the first direction e1 and perpendicular to the axial direction of the motor 2. Thus, the plugging and matching of the first pressing plate 6 and the second pressing plate 7 can achieve pre-positioning during the assembly process of the first pressing plate 6 and the second pressing plate 7, which is convenient for the subsequent installation of the fasteners. After the first pressing plate 6 and the second pressing plate 7 are connected by the fasteners, the plugging and matching position of the first pressing plate 6 and the second pressing plate 7 can also provide a good limiting effect, thereby improving the stability of the connection between the first pressing plate 6 and the second pressing plate 7.

A guide protrusion 73 is formed on one of the first side and the second side, and a guide groove 64 that cooperates with the guide protrusion 73 is formed on the other of the first side and the second side. Therefore, during the assembly process of the first pressing plate 6 and the second pressing plate 7, the first pressing plate 6 and the second pressing plate 7 can be assembled in the correct direction through the cooperation between the guide protrusion 73 and the guide groove 64, which is conducive to reducing the positioning difficulty when assembling the first pressing plate 6 and the second pressing plate 7 to improve the assembly efficiency of the first pressing plate 6 and the second pressing plate 7.

That is to say, the second pressing plate 7 is connected to the chassis 3 by a clamping structure and the chassis 3 is connected to the chassis 3 by a fastener, which can improve the connection strength between the second pressing plate 7 and the chassis 3, wherein the clamping connection structure is easy to operate, and does not require the use of additional fasteners for connection, and does not require the use of tools for matching and separating the clamping connection structure, such as the operator can directly match and separate the clamping connection structure by hand. Therefore, through the clamping connection structure between the second pressing plate 7 and the chassis 3, the connection position between the second pressing plate 7 and the chassis 3 can be increased to improve the connection stability, and a pre-positioning effect can be provided for the fastener connection, thereby reducing the difficulty of the fastener fastening the second connecting lug 71 and the third connecting lug 75.

Therefore, the cooperation of the isomorphic block 36 and the hook 76 can better limit the freedom of movement of the second pressing plate 7 relative to the chassis 3, so as to improve the stability of the connection between the second pressing plate 7 and the chassis 3. In a specific example, the block 36 is formed as an edge of the chassis 3 located at one end of the motor 2 away from the wind wheel 1, so that the process of separately setting the block 36 can be omitted. Among them, in the axial direction of the motor 2, at least one of the hook 76 and the block 36 has side walls that are opposite in the first direction e1 and extend obliquely in a direction toward the direction close to the installation space and away from each other.

Specifically, the third spring buckle 77 and the hook 76 are arranged at intervals along the circumference of the motor 2, and the third spring buckle 77 includes a second elastic arm and a second protrusion. One end of the second elastic arm is connected to the side of the second pressure plate 7 in the axial direction of the motor 2 away from the installation space, and the other end of the second elastic arm extends in the axial direction of the motor 2 away from the installation space.

[0097] When removing the first pressure plate 6 from the motor cover 5 and the second pressure plate 7, first remove the screws on the first connecting lug 63, and then push the first spring buckle 513 to disengage the first spring buckle 513 from the first pressure plate 6, and the first pressure plate 6 can be rotated and lifted by the anti-disengagement buckle 616. During this process, the second spring buckle 615 disengages from the third limiting groove 515 until the positioning protrusion 65 disengages from the positioning groove 72.

[0098] When installing the first pressure plate 6 to the combined structure of the motor cover 5, the chassis 3 and the second pressure plate 7, first insert the positioning protrusion 65 into the positioning groove 72, and then repeat the steps of installing the first pressure plate 6 to the motor cover 5.
