Description

Technical Field

[0001] This application belongs to the field of motor technology, and in particular relates to a drive motor. Background Technology

[0002] Drive motors are widely used in various fields such as industrial production and transportation. During operation, the internal windings, iron core, and other components of the motor generate a large amount of heat due to energy loss. If this heat cannot be dissipated in time, the internal temperature of the motor will continue to rise, which will not only reduce the motor's operating efficiency and output power, but may also accelerate the aging of the internal insulation materials, shorten the motor's service life, and in severe cases, even cause motor failure, affecting the stable operation of the entire equipment system.

[0003] Currently, most drive motors on the market have built-in cooling structures to handle the heat generated during operation. Common built-in cooling structures include heat sinks on the surface of the motor housing, which increase the contact area with the air and allow heat to dissipate through natural air convection. Some drive motors also have air-cooling channels inside the housing or at the ends, which, together with the motor's built-in fan or an external auxiliary fan, accelerate airflow and improve heat dissipation.

[0004] However, in practical applications, these built-in heat dissipation structures still suffer from insufficient heat dissipation capacity. When the drive motor is under high load and operates continuously for extended periods, the heat generated increases significantly. The heat dissipation efficiency of existing built-in heat dissipation structures is insufficient to meet the need for rapid heat dissipation, causing the internal temperature of the motor to exceed the ideal operating temperature range. Improvements are needed in this regard. Utility Model Content

[0005] The purpose of this application is to provide a drive motor that can solve the above-mentioned problems.

[0006] The purpose of this application is to provide a drive motor, including a motor body, wherein an output shaft is rotatably connected inside the motor body, and two parts are respectively mounted on both sides of the motor body: The first heat dissipation component includes a first heat dissipation end cover, a second heat dissipation end cover located on both sides of the motor body, and a first heat dissipation structure disposed on the first heat dissipation end cover and the second heat dissipation end cover. The second heat dissipation assembly includes a heat dissipation cover installed on the outside of the second heat dissipation end cover and a second heat dissipation structure connected to the heat dissipation cover. The motor body is also equipped with heat dissipation fins.

[0007] The aforementioned drive motor provides rotational support for the output shaft, ensuring the basic function of the drive motor, with the output shaft rotatably connected to the motor body. A first and second heat dissipation assembly are respectively installed on both sides of the motor body, forming a heat dissipation guide to channel heat away from the motor's interior. The end cap structure of the first heat dissipation assembly protects both sides of the motor body, while the two heat dissipation assemblies enhance heat dissipation capacity. Externally mounted heat dissipation fins increase the contact area between the motor body and the air, allowing heat from the motor body surface to be transferred to the air more quickly, achieving external heat dissipation. Furthermore, the heat dissipation fins, together with the inner and outer first and second heat dissipation assemblies, form a comprehensive heat dissipation system, effectively solving the problem of insufficient heat dissipation capacity in existing drive motors under high load and long-term operation, extending the overall service life of the motor, and reducing motor failures caused by overheating.

[0008] Furthermore, the first heat dissipation structure includes: Fins are arranged radially on the sidewall of the heat dissipation end cover, and heat dissipation outlets are formed between adjacent fins; The air inlet is located on the second heat dissipation end cover; The surface of the heat dissipation end cover is also provided with mounting holes for installation.

[0009] The radially arranged fins on the sidewalls of the heat sink maximize the use of the sidewall space compared to traditional, neatly arranged heat dissipation structures, significantly increasing the heat dissipation area. This allows heat transferred from the motor to the end cover to dissipate quickly through a larger surface area of ​​the fins. The radial layout also guides airflow more smoothly between the fins, reducing airflow resistance and accelerating heat exchange efficiency. Simultaneously, the heat dissipation outlets formed between adjacent fins provide an exhaust channel for hot air generated inside the motor, promptly removing accumulated hot air and preventing it from circulating inside the motor and causing a continuous temperature rise, thus ensuring unobstructed heat transfer within the motor.

[0010] Meanwhile, the air inlet on the second heat dissipation end cover can cooperate with the subsequent second heat dissipation component to provide an entrance for the cool air supplied by the second heat dissipation component to enter the motor body. In addition, the mounting holes on the surface of the heat dissipation end cover can facilitate the installation and fixation of the heat dissipation end cover of the first heat dissipation component to the motor body or other components, ensuring the stability of the connection, preventing the end cover from shifting due to vibration during operation, and the mounting holes do not damage the overall heat dissipation structure of the heat dissipation end cover.

[0011] Furthermore, the heat dissipation end cap is provided with an inwardly recessed groove, and the mounting hole is located in the groove.

[0012] The recessed groove design on the heat dissipation end cover prevents the mounting holes from protruding from the surface of the heat dissipation end cover, avoiding the need for fasteners to occupy additional external space during installation. This makes the overall structure of the drive motor more compact, adaptable to more different installation scenarios, and especially in equipment systems with limited space, it can better coordinate with the layout of other components.

[0013] Furthermore, the second heat dissipation structure includes: A cooling top cover is mounted on the heat dissipation outer cover and is connected to the heat dissipation outer cover; A cooling fan is installed inside the cooling top cover and connected to a drive unit; The cooling top cover is equipped with an intake port, through which the cooling fan draws in coolant and delivers it to the heat dissipation cover.

[0014] The cool air inside the heat dissipation cover enters the motor body through the air inlet to dissipate heat, and is finally discharged from the heat dissipation outlet. At the same time, the cool air inside the cooling top cover is also discharged through the air outlet channel to dissipate heat from the heat dissipation fins. The heat dissipation cover installed on the second heat dissipation end cover provides a channel for the delivery of cool air, ensuring that the cool air drawn in by the cooling fan is concentrated and directed to the air inlet of the motor body, preventing the cool air from being dispersed and lost during transmission, and improving the utilization rate of cool air; at the same time, the heat dissipation cover also protects the internal structure of the second heat dissipation component.

[0015] The cooling top cover and the heat dissipation outer cover are connected, forming a cold air delivery path. This allows cold air from the cooling top cover to enter the heat dissipation outer cover and then flow to the motor body, ensuring the airflow channel is sealed and further improving heat dissipation efficiency. The cooling top cover also provides a mounting platform for the cooling fan, ensuring the stability of the fan during operation. The cooling fan installed in the cooling top cover, driven by the drive unit (motor), actively draws in cold air from the intake port, providing a continuous and stable cooling airflow to the motor, improving the initiative and stability of heat dissipation. The intake port on the cooling top cover provides an inlet for cold air to enter the second heat dissipation component. After entering through the intake port, the cold air is delivered to the inside of the motor body through the heat dissipation outer cover and guided to the heat dissipation fins through the exhaust channel. This dissipates heat from both the inside of the motor and the external heat dissipation fins, further improving the overall heat dissipation effect. In addition, the motor of this application is used indoors and in a dry environment.

[0016] Furthermore, the cooling top cover and the heat dissipation outer cover are respectively provided with a first connecting pipe and a second connecting pipe, and the two connecting pipes are connected by a flange and fasteners.

[0017] The first connecting pipe on the cooling top cover mates with the second connecting pipe on the heat dissipation outer cover, providing a mating structure for the connection between the two and ensuring quick positioning and installation. The flange connection increases the contact area between the first and second connecting pipes, enhancing the sealing performance of the connection and preventing cold air leakage at the joint. Furthermore, the first and second connecting pipes are interconnected, allowing cold air to be transferred through both pipes.

[0018] Furthermore, an air outlet channel is formed between the heat dissipation outer cover and the second heat dissipation end cover, and the outlet of the air outlet channel is located on one side of the heat dissipation fins.

[0019] The air outlet channel formed between the heat dissipation outer cover and the second heat dissipation end cover utilizes the existing component space without occupying too much external installation space of the motor. The air outlet channel can guide the cold air delivered by the cooling top cover. After entering the motor body for heat dissipation, part of the cold air can be discharged through the air outlet channel, while another part of the cold air can be directly diverted to the heat dissipation fins through the air outlet channel, so that the cold air can directly act on the surface of the heat dissipation fins, accelerate the dissipation of heat on the fins, improve the heat dissipation effect of the fins, and at the same time ensure smooth airflow around the motor without affecting the overall heat dissipation environment of the motor.

[0020] Furthermore, a filter screen is provided on the intake of the cooling top cover.

[0021] The filter screen on the cooling top cover intake can effectively filter dust, impurities, debris and other pollutants in the air before the cold air enters the second heat dissipation component. This prevents these pollutants from entering the cooling top cover, heat dissipation cover and motor body with the cold air, and prevents pollutants from adhering to the cooling fan blades. At the same time, it can also prevent pollutants from entering the motor body and adhering to the windings, iron core surface or blocking the internal heat dissipation channels of the motor, thereby reducing the risk of motor failure.

[0022] The beneficial effects of this application are: 1. The first heat dissipation component and the second heat dissipation component are respectively installed on both sides of the motor body to form a heat dissipation guide, which can dissipate the heat inside the motor; and the end cover structure of the first heat dissipation component can protect both sides of the motor body, while the two heat dissipation components can enhance the heat dissipation capacity. 2. The heat dissipation fins installed on the outside of the motor body increase the contact area between the motor body and the air, so that the heat on the surface of the motor body can be transferred to the air more quickly through the fins, realizing external heat dissipation of the motor; and the heat dissipation fins, together with the first and second heat dissipation components on the inner and outer sides, form an all-round heat dissipation that combines internal heat dissipation with external heat dissipation. 3. After entering through the intake port, the cold air is delivered to the motor body through the heat dissipation cover and guided to the heat dissipation fins through the air outlet channel. This not only dissipates heat inside the motor but also cools the heat dissipation fins on the outside of the motor, further improving the overall heat dissipation effect.

[0027] The drive motor provided in the embodiments of this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0028] Example 1: like Figures 1 to 3 As shown, this application embodiment provides a drive motor, including a motor body 100, an output shaft 110 rotatably connected inside the motor body 100, and two sides of the motor body 100 respectively equipped with: The first heat dissipation component includes a first heat dissipation end cover 200, a second heat dissipation end cover 300 located on both sides of the motor body 100, and a first heat dissipation structure 400 disposed on the first heat dissipation end cover 200 and the second heat dissipation end cover 300. The second heat dissipation assembly includes a heat dissipation cover 500 installed on the outside of the second heat dissipation end cover 300 and a second heat dissipation structure 600 connected to the heat dissipation cover 500. The motor body 100 is also equipped with heat dissipation fins 120.

[0029] In some embodiments of this application, such as Figure 1 As shown, the aforementioned drive motor provides rotational support for the output shaft 110, ensuring the basic functions of the drive motor. The output shaft 110 is rotatably connected to the motor body 100. The first and second heat dissipation components are respectively installed on both sides of the motor body 100, forming a heat dissipation guide to channel heat away from the motor's interior. The end cap structure of the first heat dissipation component protects both sides of the motor body 100, while the two heat dissipation components enhance heat dissipation capacity. The heat dissipation fins 120 installed on the outside of the motor body 100 increase the contact area between the motor body 100 and the air, allowing heat from the surface of the motor body 100 to be transferred to the air more quickly through the fins, achieving external heat dissipation. Furthermore, the heat dissipation fins 120, together with the inner and outer first and second heat dissipation components, form an all-around heat dissipation system, effectively solving the problem of insufficient heat dissipation capacity of existing drive motors under high load and long-term operation, extending the overall service life of the motor, and reducing motor failures caused by overheating.

[0030] Example 2: This application provides a drive motor, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0031] like Figures 1 to 3 As shown, the first heat dissipation structure 400 includes: Fins 410 are arranged radially on the sidewall of the heat dissipation end cover, and heat dissipation outlets 420 are formed between adjacent fins 410. The air inlet 430 is located on the second heat dissipation end cover 300; The surface of the heat dissipation end cover is also provided with mounting holes 450 for installation.

[0032] In this embodiment, the fins 410, radially mounted on the sidewall of the heat dissipation end cover, maximize the use of the sidewall space of the end cover compared to the traditional regularly arranged heat dissipation structure, significantly increasing the heat dissipation area. This allows the heat transferred from the motor to the end cover to be quickly dissipated through the surface of more fins 410. The radial layout also guides air to form a smoother flow path between the fins 410, reducing airflow resistance and accelerating the heat exchange efficiency between heat and air. At the same time, the heat dissipation outlets 420 formed between adjacent fins 410 provide an exhaust channel for the hot air generated inside the motor, enabling timely removal of the hot air accumulated inside the motor. This prevents the hot air from circulating inside the motor and causing the temperature to rise continuously, ensuring a smooth heat transfer path inside the motor.

[0033] Meanwhile, the air inlet 430 on the second heat dissipation end cover 300 can cooperate with the subsequent second heat dissipation component to provide an inlet for the cold air supplied by the second heat dissipation component to enter the motor body 100. In addition, the mounting holes 450 provided on the surface of the heat dissipation end cover can facilitate the installation and fixation of the heat dissipation end cover of the first heat dissipation component to the motor body 100 or other components, ensuring the stability of the connection and preventing the end cover from shifting due to vibration during operation. Moreover, the installation holes 450 do not damage the overall heat dissipation structure of the heat dissipation end cover.

[0034] Furthermore: the heat dissipation end cover is provided with an inwardly recessed groove 440, and the mounting hole 450 is located in the groove 440.

[0035] The recessed groove 440 on the heat dissipation end cover prevents the mounting hole 450 from protruding from the surface of the heat dissipation end cover, avoiding the fasteners from occupying extra external space during installation. This makes the overall structure of the drive motor more compact and adaptable to more different installation scenarios. Especially in equipment systems with limited space, it can better coordinate the layout with other components.

[0036] Example 3: This application provides a drive motor, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0037] like Figures 1 to 3 As shown, the second heat dissipation structure 600 includes: A cooling top cover 610 is mounted on a heat dissipation outer cover 500 and is connected to the heat dissipation outer cover 500; A cooling fan 620 is disposed inside the cooling top cover 610 and connected to a drive unit 630; The cooling top cover 610 is provided with an intake port 611, and the cooling fan 620 draws in the cooling through the intake port 611 and delivers it to the heat dissipation cover 500.

[0038] In this embodiment, the cold air inside the heat dissipation cover 500 enters the motor body 100 through the air inlet 430 to dissipate heat, and is finally discharged from the heat dissipation outlet 420. At the same time, the cold air inside the cooling top cover 610 is also discharged through the air outlet 660 to dissipate heat on the heat dissipation fins 120. The heat dissipation cover 500, installed on the second heat dissipation end cover 300, provides a channel for the delivery of cold air, ensuring that the cold air drawn in by the cooling fan 620 can be concentrated and guided to the air inlet 430 of the motor body 100, avoiding the dispersion and loss of cold air during transmission, and improving the utilization rate of cold air; at the same time, the heat dissipation cover 500 can also protect the internal structure of the second heat dissipation component.

[0039] The cooling top cover 610 is connected to the heat dissipation outer cover 500, forming a cold air delivery path. This allows the cold air inside the cooling top cover 610 to enter the heat dissipation outer cover 500 and then flow to the motor body 100, ensuring the airflow channel is sealed and further improving heat dissipation efficiency. The cooling top cover 610 also provides a mounting platform for the cooling fan 620, ensuring the stability of the fan during operation. The cooling fan 620, installed inside the cooling top cover 610, can actively draw in cold air from the intake port 611 under the drive of the drive unit 630, continuously and stably providing cooling airflow to the motor, improving the initiative and stability of heat dissipation. Here, the drive unit 630 is the motor. The intake port 611 on the cooling top cover 610 provides an inlet for cold air to enter the second heat dissipation component. After entering through the intake port 611, the cold air is delivered to the inside of the motor body 100 through the heat dissipation cover 500 and guided to the heat dissipation fins 120 through the air outlet 660. This not only dissipates heat inside the motor but also cools the heat dissipation fins 120 outside the motor, further improving the overall heat dissipation effect. In addition, the motor of this application is used indoors and must be used in a dry environment.

[0040] Furthermore, the cooling top cover 610 and the heat dissipation outer cover 500 are respectively provided with a first connecting pipe 640 and a second connecting pipe 650, and the two connecting pipes are connected by a flange and fasteners.

[0041] The first connecting pipe 640 on the cooling top cover 610 mates with the second connecting pipe 650 on the heat dissipation outer cover 500, providing a mating structure for the connection between the cooling top cover 610 and the heat dissipation outer cover 500, ensuring quick positioning and installation. The flange connection increases the contact area between the first connecting pipe 640 and the second connecting pipe 650, enhancing the sealing performance of the connection and preventing cold air leakage at the connection point. Furthermore, the first connecting pipe 640 and the second connecting pipe 650 are interconnected, allowing cold air to be transferred through both pipes.

[0042] Example 4: This application provides a drive motor, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0043] like Figures 1 to 3 As shown, an air outlet channel 660 is formed between the heat dissipation outer cover 500 and the second heat dissipation end cover 300, and the outlet of the air outlet channel 660 is located on one side of the heat dissipation fins 120.

[0044] In this embodiment, the air outlet channel 660 formed between the heat dissipation cover 500 and the second heat dissipation end cover 300 utilizes the existing component space without occupying too much external installation space of the motor. The air outlet channel 660 can guide the cold air delivered by the cooling top cover 610. After a portion of the cold air enters the motor body 100 for heat dissipation, it can be discharged through the air outlet channel 660. Another portion of the cold air can be directly diverted to the heat dissipation fins 120 through the air outlet channel 660, so that the cold air can directly act on the surface of the heat dissipation fins 120, accelerate the dissipation of heat on the fins, improve the heat dissipation effect of the fins, and at the same time ensure smooth airflow around the motor without affecting the overall heat dissipation environment of the motor.

[0045] Example 5: This application provides a drive motor, which, in addition to the above-mentioned technical features, also includes the following technical features.

[0046] like Figure 1 As shown, a filter screen 700 is provided on the suction port 611 of the cooling top cover 610.

[0047] In this embodiment, the filter 700 on the intake 611 of the cooling top cover 610 can effectively filter dust, impurities, debris and other pollutants in the air before the cold air enters the second heat dissipation component, preventing these pollutants from entering the cooling top cover 610, the heat dissipation outer cover 500 and the motor body 100 with the cold air, preventing pollutants from adhering to the blades of the cooling fan 620, and also preventing pollutants from adhering to the windings, the iron core surface or blocking the internal heat dissipation channels of the motor after entering the motor body 100, thereby reducing the risk of motor failure.
