Common structural elements or the same kind of structural elements are given the same reference numerals in the various drawings, and repeated description of them is appropriately omitted.

[0062] Figure 1 A three-dimensional structure schematic diagram of a fan system is provided for the embodiments of the utility model. Figure 2 A three-dimensional structure schematic diagram of a fan system is provided for the embodiments of the utility model. Figure 3 A three-dimensional structure schematic diagram of a fan system is provided for the embodiments of the utility model.

[0063] Referring to Figures 1-3 The embodiment of the utility model provides a fan system, including motor 1, at least two groups of fan assembly 2 and at least two groups of transmission mechanism 3. Motor 1 includes a plurality of output end 11. Each group of fan assembly 2 includes at least one fan. Transmission mechanism 3 is set up one by one with fan assembly 2. Each group of transmission mechanism 3 is set up between the output end 11 of motor 1 and fan assembly 2. Transmission mechanism 3 is configured to switch power transmission and disconnect between motor 1 and fan assembly 2. Wherein, each output end 11 of motor 1 corresponds to connect one or more groups of transmission mechanism 3.

[0064] Referring to Figures 1-3 Motor 1 includes at least two output ends 11, and the two output ends 11 can be coaxial or separate multiple motor shafts, with each motor shaft serving as an output end 11.

[0065] Motor 1 includes a rotor, a stator and a motor shaft. In some embodiments, the rotor adopts a multi-channel structure and can drive multiple output ends 11 of motor 1 simultaneously. In other embodiments, there is only one motor shaft, which passes through the center channel of the rotor, and both ends of the motor shaft extend out of the rotor of motor 1. Both ends of the motor shaft serve as output ends 11. When motor 1 is running, each output end 11 can obtain power. The stator part includes multiple windings, which can be independently controlled as needed to achieve different rotational speeds and torque outputs.

[0066] Motor 1 adopts a multi-output end structure design, which saves the overall space of the fan system and is conducive to realizing the miniaturization of the fan system. In addition, the multiple output ends of motor 1 can work simultaneously or partially, improving the overall system efficiency and expanding the working mode. Especially in scenarios where multiple output ends 11 need to work, production efficiency can be significantly improved. In addition, the above motor 1 has fewer failure points and is easier to troubleshoot, which can reduce maintenance costs.

[0067] The number of fan assemblies 2 is multiple, and each group of fan assemblies 2 can include one or more fans 21. The number of fans 21 included in each group of fan assemblies 2 can be the same or different. The fan assemblies 2 are more flexible in setting. The first power input shaft 212 of the multiple fans 21 in each group of fan assemblies 2 is coaxial, which can realize centralized driving and more efficient power transmission with less energy loss. One group of fan assemblies 2 only needs to correspond to one output end 11 of motor 1, and the number of required power sources is less, which can greatly simplify the structure of the fan system.

[0068] The transmission mechanism 3 is used to realize the transmission of power from the motor 1 to the fan assembly 2. All the fans 21 of each fan assembly 2 are configured to start simultaneously and stop simultaneously. Each fan assembly 2 is equipped with a transmission mechanism 3. The power between each fan assembly 2 and the motor 1 can be switched between transmission and disconnection. When the power between the fan assembly 2 and the motor 1 can be transmitted, all the fans 21 of the fan assembly 2 can be driven by the motor 1, the fan assembly 2 is full load, and the air volume of the fan system is large. When the power between the fan assembly 2 and the motor 1 is disconnected, the power output by the motor 1 cannot be transmitted to the fan assembly 2, and all the fans 21 of the fan assembly 2 are stopped, the fan assembly 2 does not blow air, and the air volume of the entire fan system is small. This control mode takes into account the flexibility and individualization of fan system control, and can better meet the application requirements of different scenes.

[0069] As described above, the fan system includes multiple fan assemblies 2, and each fan assembly 2 is equipped with a transmission mechanism 3, so the working state of each fan assembly 2 is independent and does not affect each other. When one of the fan assemblies 2 needs to be stopped or started, the working state of the other fan assemblies 2 is not affected.

[0070] The corresponding relationship between the output end 11 of the motor 1, the fan assembly 2, and the transmission mechanism 3 has multiple embodiments. Figure 1 The first embodiment is shown. In the first embodiment, the motor 1 has a motor shaft, both ends of the motor shaft can be used as the output end 11, and the motor 1 has two output ends 11. Each output end 11 is connected to a transmission mechanism 3, and each transmission mechanism 3 is connected to a fan assembly 2. This structure requires fewer motor shafts, the fan system is more compact, and is conducive to miniaturization and light weight.

[0071] In some embodiments, each output end 11 of the motor 1 is symmetrically distributed relative to the center of the motor 1. The fan system is more symmetrical in arrangement and has better bearing performance.

[0072] In some embodiments, each transmission mechanism 3 includes a driving wheel 31, a driven wheel 32, and a state switching mechanism 33. The driving wheel 31 is fixedly connected to the output end 11 of the motor 1; the driven wheel 32 is fixedly connected to the first power input shaft 212 of the fan assembly 2. The state switching mechanism 33 is installed on the driven wheel 32; the state switching mechanism 33 is configured to switch the power transmission and disconnection between the driving wheel 31 and the driven wheel 32.

[0073] The driving wheel 31 is always drivingly connected to the output end 11 of the motor 1. As long as the motor 1 rotates, the driving wheel 31 rotates with the motor 1, regardless of whether the fan 21 of the fan assembly 2 where the driving wheel 31 is located needs to work.

[0074] The driven wheel 32 is a shaft that is always drivingly connected with the first power input shaft 212 of the fan assembly 2, and the connection between the two can be fixed connection, etc. When the driving wheel 31 and the driven wheel 32 are drivingly connected, power can be transmitted from the driving wheel 31 to the driven wheel 32. When the driving wheel 31 and the driven wheel 32 are disconnected, power cannot be transmitted from the driving wheel 31 to the driven wheel 32.

[0075] The state switching mechanism 33 is a mechanism that realizes the power transmission and disconnection between the driving wheel 31 and the driven wheel 32. The state switching mechanism 33 can have various implementation forms, such as using a pin shaft. When the driving wheel 31 and the driven wheel 32 need to be drivingly connected, the pin shaft is inserted into the corresponding pin shaft hole of the driving wheel 31 and the driven wheel 32, so that the driving wheel 31 and the driven wheel 32 are fixedly connected, and power can be transmitted from the driving wheel 31 to the driven wheel 32.

[0076] Referring to Figures 1-3 In some embodiments, the state switching mechanism 33 includes a mounting portion 331, a thrust 332, an elastic retaining member (not shown), and a rotating claw 333. The mounting portion 331 is mounted to the housing of the motor 1. The thrust 332 includes a base 332a and an extension rod 332b. The base 332a is mounted to and supported by the mounting portion 331. The extension rod 332b is telescopically mounted to the base 332a. The rotating claw 333 includes a first end 333a, an intermediate portion 333b, and a second end 333c arranged in sequence. The first end 333a of the rotating claw 333 is located on the movement path of the thrust 332. The intermediate portion 333b of the rotating claw 333 is rotatably connected to the driven wheel 32 by the elastic retaining member. The elastic retaining member is, for example, a torsion spring or the like. When the extension rod 332b of the thrust 332 is in a retracted state, the second end 333c of the rotating claw 333 is drivingly connected to the driving wheel 31 under the action of the elastic retaining member. When the extension rod 332b of the thrust 332 is in an extended state, the extension rod 332b overcomes the elastic force of the elastic retaining member and drives the first end 333a of the rotating claw 333 to rotate around the rotatable connection between the rotating claw 333 and the driven wheel 32, so that the second end 333c of the rotating claw 333 is separated from the driving wheel 31. The second end 333c of the rotating claw 333 can be connected to the driving wheel 31 in various ways, such as by using buckles, plugs, etc.

[0077] Referring to Figure 2 and Figure 3 In some embodiments, the edge of the driving wheel 31 is provided with a ratchet 311, and the second end 333c of the rotating claw 333 is provided with a hook 333d, and the ratchet 311 cooperates with the hook 333d. With this structure, when driving connection is needed, the driving connection between the ratchet 311 and the hook 333d is reliable; when driving connection is not needed, the ratchet 311 and the hook 333d can also be easily separated.

[0078] Referring to Figure 2 , when the driving wheel 31 and the driven wheel 32 are drivingly connected, the ratchet teeth 311 and the hooks 333d are hooked together, the driving wheel 31 rotates under the driving of the motor 1, and the driven wheel 32 also rotates. Figure 3 , when the driving wheel 31 and the driven wheel 32 are disconnected, the ratchet teeth 311 and the hooks 333d are separated, although the driving wheel 31 rotates under the driving of the motor 1, the driven wheel 32 remains stationary and does not rotate with the driving wheel 31.

[0079] Continuing to refer to Figure 2 and Figure 3 , in some embodiments, the driving wheel 31 and the driven wheel 32 are arranged adjacent to and coaxially; the diameter of the driven wheel 32 is greater than that of the driving wheel 31; the rotating claw 333 is installed on the side of the driven wheel 32 facing the driving wheel 31, and the rotating claw 333 is located outside the edge of the driving wheel 31. Without the need to achieve driving connection, the position of the rotating claw 333 does not affect the normal rotation of the driving wheel 31 at all.

[0080] In some embodiments, the driven wheel 32 is provided with one or more weight-reducing holes 321. The size of each weight-reducing hole 321 can be the same or different. The weight-reducing holes 321 can be arranged in a circle around the central axis of the driven wheel 32. Designing the weight-reducing holes 321 can effectively reduce the overall weight of the driven wheel 32, making the rotation of the driven wheel 32 more light and efficient, and helping to improve the energy efficiency and performance of the fan system. In addition, without affecting the structural strength, the material used by the driven wheel 32 is reduced. The weight-reducing holes 321 can also increase air circulation, improve the heat dissipation performance of the transmission mechanism 3, reduce the temperature of the transmission mechanism 3, and thus prolong the service life of the transmission mechanism 3.

[0081] In some embodiments, the number of weight-reducing holes 321 is multiple, and the multiple weight-reducing holes 321 are symmetrically distributed along the central axis of the driven wheel 32. Symmetrically arranging the weight-reducing holes 321 can make the structure of the driven wheel 32 more uniform and stable, reduce deformation caused by the asymmetric structure of the driven wheel 32, make the driven wheel 32 maintain good mechanical properties, and improve the overall strength and durability of the driven wheel 32.

[0082] Back to Figure 1 , in some embodiments, the mounting portion 331 of each transmission mechanism 3 is integrated or fixedly connected. All the mounting portions 331 are fixedly connected with the shell of the motor 1, the mounting portion 331 is very stable, and the installation of the thrust stopper 332 will also be very firm.

[0083] The mounting portions 331 of all the transmission mechanisms 3 are fixedly connected together, which can effectively enhance the structural stability of the state switching mechanism 33, is favorable for dispersing external load, reduces local stress concentration, improves the impact resistance and fatigue resistance of the transmission mechanism 3, and helps to improve the service life of the transmission mechanism 3. In addition, the mounting portions 331 of all the transmission mechanisms 3 are fixedly connected together, the number and complexity of parts are reduced, the assembly and positioning process of the mounting portion 331 is more accurate and efficient. While facilitating maintenance, overall inspection can also be more conveniently carried out.

[0084] Figure 4 A three-dimensional structure schematic diagram of a fan system is provided for another embodiment of the utility model.

[0085] Referring to Figure 4 , another embodiment of the corresponding relationship between the output end 11 of the motor 1, the fan assembly 2 and the transmission mechanism 3 will be introduced below.

[0086] Secondly, referring to Figure 4 , the motor 1 includes at least two motor shafts, each motor shaft includes at least one output end 11, and each output end 11 is connected to a group of transmission mechanisms 3.

[0087] In the above technical solution, the motor 1 realizes multi-point driving through multiple motor shafts, without the need to set multiple motors 1, thereby improving the flexibility and efficiency of the fan system, simplifying the structure of the fan system and reducing the overall cost and space occupation of the fan system. The motor 1 system adopts multiple motor shafts, which can realize more uniform load distribution. Through reasonable design of the layout of the motor shafts, power can be effectively distributed to each fan assembly 2, avoiding the risk of failure caused by overload of a single motor shaft, improving the reliability of the motor 1 and prolonging the service life of each motor 1. When a motor shaft of the motor 1 fails, it will not affect the normal work of other motor shafts.

[0088] In addition, the design of the motor 1 with multiple motor shafts also facilitates the realization of complex motion control. Through independent control of different motor shafts, multiple motion modes such as synchronous, asynchronous or variable speed motion can be realized. Such flexibility makes the fan system more adaptable to different working requirements. When maintenance and repair are needed, only one motor 1 needs to be checked and maintained, reducing the complexity and time cost of maintenance. Fault diagnosis is also more convenient, which can quickly locate the problem. Finally, this design can also reduce the energy consumption of the fan system. Through optimization of the running state and load distribution of the motor 1, a higher energy efficiency ratio can be realized, reducing unnecessary energy waste.

[0089] Figure 5 A three-dimensional structure schematic diagram of a fan system is provided for another embodiment of the utility model.

[0090] Referring toFigure 5 The following describes some further embodiments of the correspondence between the output terminal 11 of motor 1, the fan assembly 2, and the transmission mechanism 3.

[0091] The third type, see [link] Figure 5 As shown, the motor 1 has a motor shaft. One end of the motor shaft forms multiple output ends 11 via a transfer case 4. Each output end 11 is connected to multiple transmission mechanisms 3, and each transmission mechanism 3 is connected to a fan assembly 2. In the third embodiment, since one output end 11 of the motor 1 needs to be connected to multiple transmission mechanisms 3, an intermediate component can be provided to achieve the connection. The transfer case 4 can be implemented in various ways, such as using a gear mechanism.

[0092] In some embodiments, the transfer case 4 includes at least two power output shafts 41, each power output shaft 41 being connected to a set of transmission mechanisms 3. This approach can further simplify the structure of the motor 1 and enable flexible, grouped control of the fan assembly 2.

[0093] If motor 1 has only one motor shaft, the transfer case 4 is driven by that single motor shaft to divide the power from one source into multiple sources. If motor 1 has multiple motor shafts, the transfer case 4 is driven by one of those shafts to divide the power from that single shaft into multiple sources. In practical applications, the structure and number of transfer cases 4 are determined based on the required number of power sources.

[0094] In some embodiments, the transfer case 4 further includes a second power input shaft 42, a gear mechanism (not shown), and multiple power output shafts 41. The second power input shaft 42 is drivenly connected to the output end 11 of the motor 1. The gear mechanism is drivenly connected to the second power input shaft 42. The second power input shaft 42 is drivenly connected to each of the power output shafts 41 via the gear mechanism.

[0095] The transfer case 4 employs a gear mechanism, which can effectively distribute power from one input source to multiple output terminals 11, improving the system's flexibility and adaptability. Furthermore, by setting different gear ratios, different transmission ratios and torque distributions can be achieved to meet the needs of various operating conditions. By adjusting the gear combination, the transfer case 4 can switch between high and low speeds, optimizing power output and improving work efficiency.

[0096] This utility model provides an air conditioner, including a fan system provided by any of the technical solutions of this utility model. The fan system adopts a single-motor, multi-fan structure, and can, according to working needs, enable some fans 21 to start working while others stop working; or all fans 21 can be started working. The fan system offers flexible control, requires fewer motors 1, and has a more compact structure.
