Description

Technical Field

[0001] This utility model relates to the field of integrated motor drive machines, specifically an integrated motor drive machine, an air guide structure, and a fan heat dissipation component. Background Technology

[0002] A motor and driver integrated into one unit is called an all-in-one machine. Compared to separate motors and drivers, all-in-one machines have higher integration, smaller size, and higher level of intelligence. Because all-in-one machines integrate the motor body and driver, they generate more heat than a single motor, placing higher demands on their cooling systems. Due to the structural limitations of the motor, all-in-one machines cannot use higher-power fans, thus limiting the motor's power. Therefore, most all-in-one machines on the market have relatively low power outputs, and their cooling systems need to be more efficient. Utility Model Content

[0044] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0047] Furthermore, in this utility model, the use of terms such as "first," "second," etc., is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0048] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0049] Combination Figures 1-10 As shown, this utility model embodiment discloses a motor-driven integrated machine 100. The motor-driven integrated machine 100 includes a duct sleeve 10, a motor 20 housed inside the duct sleeve 10, and a driver 30 disposed on the top. A heat dissipation cavity 101 is disposed on the rear side of the motor shaft 201 within the duct sleeve 10. An air guide structure 40 and a fan assembly 50 are sequentially disposed along the axial direction of the heat dissipation cavity 101. The air guide structure 40 extends toward the fan assembly 50 to guide at least a portion of the airflow generated by the fan assembly 50 to the driver 30. Understandably, the duct sleeve 10 is a three-sided enclosed duct structure with a hollow top. The duct sleeve has a U-shaped structure. The motor 20 is installed inside the duct sleeve 10, and the driver 30 is installed at the hollow top of the duct sleeve 10, covering at least a portion of the duct sleeve 10. By setting the air guide structure 40 inside the heat dissipation cavity 101, the air guide structure 40 occupies the empty space inside the heat dissipation cavity 101, which can guide the airflow direction from the fan assembly 50, so that the airflow flows along the gap between the air guide structure 40 and the air duct sleeve 10, and the gap between the air guide structure 40 and the driver 30, reducing the chance of the airflow forming turbulence in the heat dissipation cavity, and also increasing the pressure and flow rate of the air outlet of the fan assembly 50, carrying away more heat from the all-in-one machine 100, making the entire heat dissipation system more efficient, and at the same time, meeting the high power requirements of the all-in-one machine.

[0050] like Figure 1 As shown, the driver 30 includes a capacitor assembly 301, which at least partially extends into the heat dissipation cavity 101 and is located at the top of the air guide structure 40. That is, the driver 30 has an opening at its bottom, through which the capacitor assembly 301 extends into the heat dissipation cavity 101. Airflow is generated by the fan assembly 50 and blown onto the capacitor assembly 301, cooling it and extending its lifespan. Understandably, the driver 30 itself has a strictly sealed structure, isolating the internal components from the external environment.

[0051] Specifically, a fan cover 501 is provided on the rear side of the fan assembly 50, and an air inlet screen is provided on the fan cover 501. Under the action of the fan assembly 50 (taking a centrifugal fan as an example in this embodiment), the airflow from the outside enters the fan assembly 50 and is thrown out from the circumference of the fan assembly. Under the action of the air guide structure 40, the airflow is blocked from turbulent flow in the heat dissipation cavity 101, thereby guiding most of the airflow to the driver 30 at the top of the heat dissipation cavity 101. Thus, the airflow can effectively dissipate heat for the capacitor assembly 301 and flow along the capacitor assembly 301 towards... The airflow flows forward into the duct between the driver 30 and the motor 20. Specifically, the driver 30 has heat dissipation fins 302 on the bottom wall facing the duct sleeve 10. After being guided by the air guide structure 40, a portion of the airflow flowing towards the driver 30 flows into the duct space between the heat dissipation fins 302 and the motor 20, while another portion flows through the capacitor assembly 301 into the duct space between the heat dissipation fins 302 and the motor 20, thereby further dissipating heat from the housings of the driver 30 and the motor 20 and their internal structures. At the same time, the air guide structure 40 can also guide the airflow ejected by the fan assembly 50 to flow into other ducts besides the driver 30 and out of the integrated machine along the ducts, thereby further dissipating heat from the motor housing and its internal structure.

[0052] like Figures 1-6 As shown, in one specific embodiment, the air guide structure 40 is a groove structure 401 with a bottom wall 4011 and a side wall 4012. The bottom wall 4011 faces the fan assembly, and the side wall 4012 faces the capacitor assembly 301 and is at least partially located below the capacitor assembly 301. The side wall 4012 of the air guide structure 40 is connected to the motor 20. Specifically, the side wall 4012 of the air guide structure 40 has a bent mounting portion 4013, which is connected to a component of the motor, such as the rear end cover 203 of the motor, through the mounting portion 4013. In this embodiment, the air guide structure 40 is an air guide shroud structure. The side wall 4012 of the air guide shroud 401 is connected to the rear end cover 203 of the motor. In this embodiment, the encoder 202 is mounted on the rear end cover 203, which acts as an encoder support. By setting the air guide shroud 401, the air guide shroud 401 acts as a rear cover of the motor, sealing the space in the rear end cover 203 where the encoder 202 is mounted. The bottom wall 4011 of the air guide shroud 401 faces the fan assembly 50 and is as close as possible to the fan assembly 50. Of course, in other modified embodiments, the motor itself can also be provided with a rear cover structure that seals the motor, and the air guide structure 40 is connected to the rear cover.

[0053] In this embodiment, the air guide shroud 401 is connected to the fan assembly 50, and the air guide shroud 401 serves as a support for the fan assembly. Specifically, the motor-driven integrated machine 100 also includes a fan adapter plate 60, which is disposed between the air guide structure 40 and the fan assembly 50, and is connected to both the air guide structure 40 and the fan assembly 50. Due to the design of the fan adapter plate 60, when it is necessary to replace or repair the fan assembly 50, it is only necessary to remove the fan cover plate 501, and then remove the fan adapter plate 60 and the fan assembly 50 together from the air guide shroud 401, thereby further disassembling the fan assembly 50. Through the function of the fan adapter plate 60, the air guide structure can be repaired without disassembling the fan assembly 50, making the repair process simple and convenient.

[0054] In other embodiments, the air guide shroud 401 may not be connected to the fan assembly. The fan assembly is provided with mounting brackets around its perimeter, and the fan assembly is fixed to the air duct sleeve through the mounting brackets.

[0055] Combination Figure 6 As shown, in a specific embodiment, the angle between the sidewall 4012 and the bottom wall 4011 of the groove structure 401 of the air guide structure 40 can be equal to 90 degrees or greater than 90 degrees. This design makes it easier to guide the gas thrown out by the fan assembly 50 to the driver.

[0056] like Figure 7 As shown, in another specific embodiment, the sidewall 4022 of the groove structure of the air guide structure 40 is an arc structure, and the angle between the tangent of the arc sidewall and the extension line of the bottom wall is 30-60 degrees. In this embodiment, the air guide structure 40 is more like a bowl-shaped structure 402. The smoothly connected arc air guide structure 40 can more easily guide the airflow thrown out by the fan assembly 50 to flow towards the capacitor assembly 301 and the driver 30.

[0057] like Figure 8-9 As shown, in another specific embodiment of this utility model, the air guiding structure 40 is an annular structure 403 with sidewalls. The sidewalls 4031 of the annular structure 403 face the capacitor assembly 301 and are at least partially located below the capacitor assembly 301. One edge of the sidewall 4031 is connected to the rear cover of the motor, and the other edge of the sidewall 4031 extends to the fan assembly 50. In this embodiment, the motor 20 is provided with a rear cover that encloses the motor. One edge of the sidewall 4031 of the annular structure 403 is connected to the rear cover of the motor, and the other edge of the sidewall 4031 extends to the fan assembly 50. Specifically, the annular structure 403 can be a flared structure, with the diameter of the flared opening gradually increasing from the end near the fan assembly 50 towards the end near the motor 20.

[0058] In one specific embodiment, the air guide structure is a box-shaped structure (not shown) with a bottom wall and a top wall. The side walls of the box-shaped structure connect the bottom wall and the top wall. The bottom wall faces the fan assembly, and the side walls face the capacitor assembly and are at least partially located below the capacitor assembly. A mounting portion is provided on the bottom wall or the top wall to connect with the motor. In this embodiment, the box-shaped air guide structure can be a hollow structure or a solid structure, as long as it occupies the empty space within the heat dissipation cavity and serves to guide the airflow.

[0059] In a specific embodiment, such as Figure 10 As shown, the radial distance between the sidewall 4012 of the air guide structure 40 facing the capacitor assembly 301 and the capacitor assembly 301 is 1-3 cm, and the radial distance between the sidewall 4012 of the air guide structure facing the air duct sleeve and the air duct sleeve 10 is 3-4 cm. This range ensures that the air guide structure 40 occupies most of the empty space in the heat dissipation cavity 101 except for the fan assembly 50, avoiding the presence of a large amount of turbulent gas in this empty space, and also ensuring that the airflow flows as far as possible towards the driver and the air duct, thereby effectively dissipating heat for the capacitor assembly of the driver, the other components of the driver, and the motor.

[0060] In one embodiment, such as Figure 3 As shown, the driver 30 is provided with a heat dissipation fin 302 on the bottom wall facing the air duct sleeve 10. The heat dissipation fin 302 dissipates heat from the driver 30. Specifically, after being guided by the air guide structure 40, part of the airflow flowing to the driver 30 flows into the air duct space between the heat dissipation fin 302 and the motor 20, and another part of the airflow flows through the capacitor assembly 301 and then into the air duct space between the heat dissipation fin 302 and the motor 20.

[0061] like Figure 1-3 As shown, a baffle plate 102 is provided on the top of the air duct sleeve 10 located in front of the driver 30, and the baffle plate 102 is arranged to enclose the air duct sleeve 10. Specifically, the baffle plate 102 is connected to the top of the two side walls of the air duct sleeve 10, and the baffle plate 102 and the hollow top of the air duct sleeve 10 form an enclosed space. By setting the baffle plate 102, the airflow flowing out from the heat dissipation fins 302 can be guided to flow closer to the motor housing, preventing the airflow from dispersing after flowing out of the driver 20, which helps to increase the fluid velocity on the housing surface and improve heat dissipation efficiency.

[0062] like Figure 4-5 As shown, a cable pass-through port is provided above the air guide structure 40. The motor power cable, encoder cable, temperature sensor cable, etc., pass through the cable pass-through port and connect to the driver. The motor power cable exits from the first cable pass-through port 405, and the encoder cable and temperature sensor cable exit from the second cable pass-through port 406. A cable pass-through plug is provided in the first cable pass-through port 405, and a sealing ring is provided in the second cable pass-through port 406.

[0063] Understandably, in a particular embodiment, the fan assembly 50 is driven by a separate fan motor.

[0064] In another embodiment of this utility model, the fan assembly 50 can also be an axial flow fan. In this case, under the action of the axial flow fan, the airflow from the outside enters the axial flow fan through the air inlet and is thrown out from the front side of the fan assembly. Under the action of the air guide structure, the airflow is blocked from turbulent flow in the heat dissipation cavity, thereby guiding most of the airflow to the driver at the top of the heat dissipation cavity. Thus, the airflow can effectively dissipate heat for the capacitor assembly and for the motor and driver. When using an axial flow fan, the air guide structure preferably adopts a groove structure with an angle greater than 90 degrees between the side wall and the bottom wall, which is more convenient for guiding the airflow of the axial flow fan.

[0065] like Figure 1-10 As shown, this utility model embodiment also proposes an air guide structure 40, which is installed on a motor drive integrated machine 100. The motor drive integrated machine 100 includes an air duct sleeve 10, a motor 20 is sleeved inside the air duct sleeve 10, and a driver 30 is provided on the top of the air duct sleeve 10. A heat dissipation cavity 101 is provided inside the air duct sleeve 10 on the rear side of the motor axis. An air guide structure 40 and a fan assembly 50 are arranged sequentially on the axial direction of the heat dissipation cavity 101. The air guide structure 40 extends toward the fan assembly 50 to guide at least part of the airflow formed by the fan assembly 50 to the driver 30.

[0066] In a specific embodiment, the driver 30 includes a capacitor assembly 301, which is at least partially located within the heat dissipation cavity 101 and on top of the airflow structure 40.

[0067] like Figure 5-6 As shown, in a specific embodiment, the air guide structure 40 is a groove structure 401 with a bottom wall and a side wall. The side wall 4012 is connected to the bottom wall 4011. The bottom wall 4011 faces the fan assembly 50, and the side wall 4012 faces the capacitor assembly 301 and is at least partially located below the capacitor assembly 301.

[0068] In a specific embodiment, the air guiding structure is a box-shaped structure with a bottom wall and a top wall. The side walls of the box-shaped structure are connected to the bottom wall and the top wall. The bottom wall faces the fan assembly, and the side walls face the capacitor assembly and are at least partially located below the capacitor assembly.

[0069] In a specific embodiment, the included angle between the sidewall and the bottom wall of the groove structure 401 is greater than or equal to 90 degrees.

[0070] like Figure 7 As shown, in a specific embodiment, the sidewall 4022 of the groove structure is an arc structure, and the angle between the tangent of the arc sidewall and the extension line of the bottom wall is 30-60 degrees. At this time, the groove structure is a bowl-shaped structure 402.

[0071] like Figure 8-9 As shown, in a specific embodiment, the air guide structure 40 has an annular structure 403 with sidewalls 4031 facing the capacitor assembly 301 and at least partially located below the capacitor assembly 301.

[0072] like Figure 10 As shown, in a specific embodiment, the radial distance between the sidewall 4012 of the air guide structure 40 facing the capacitor assembly and the capacitor assembly 301 is 1-3 cm.

[0073] In a specific embodiment, the radial distance between the side wall of the air guide structure 40 facing the air duct sleeve and the air duct sleeve 10 is 3-4 cm.

[0074] Combination Figure 4 As shown, this utility model embodiment also proposes a fan heat dissipation component 70, which is installed on a motor drive integrated machine 100. The motor drive integrated machine 100 includes a duct sleeve 10, a motor 20 is sleeved inside the duct sleeve 10, and a driver 30 is provided on the top of the duct sleeve 10. A heat dissipation cavity 101 is provided inside the duct sleeve 10 on the rear side of the motor axis. The fan heat dissipation component 70 is provided on the axial direction of the heat dissipation cavity 101. The fan heat dissipation component 70 includes an air guide structure 40 and a fan component 50 arranged sequentially along the motor axis. The air guide structure 40 extends toward the fan component to guide at least part of the airflow formed by the fan component 50 to the driver 30.

[0075] In a specific embodiment, the fan heat dissipation assembly 70 includes a fan adapter plate 60, and the air guide structure 40 is connected to the fan assembly 50 through the fan adapter plate 60.

[0076] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
