Description

Technical Field

[0001] This utility model belongs to the field of motor technology, and in particular relates to a motor with heat dissipation function. Background Technology

[0002] An electric motor (electric motor / generator) is a device that converts electrical energy into mechanical energy. Its core function is to realize the transformation of energy form through the principle of electromagnetic induction. During the operation of the motor, its internal coils, rotor and other components generate a lot of heat due to the work done by the current and mechanical friction. However, due to the limitations of the existing motor casing structure, this heat can only be dissipated by natural heat exchange with the surrounding air. Natural heat exchange mainly relies on natural air convection, and the heat transfer speed is slow, resulting in relatively low overall heat dissipation efficiency, which makes it difficult to meet the requirements of long-term stable and efficient operation of the motor. Utility Model Content

[0008] Preferably, a connecting rope is installed on the outer wall of the protective shell, and a push rod is installed on the connecting rope to be inserted into the bayonet to abut against the card block. The push rod is provided with an adjustment block for providing an operating grip point, and an elastic pad is installed on the outer wall of the protective shell to contact the push rod for shock absorption and noise reduction.

[0009] Preferably, the spring is provided with a limiting telescopic rod for limiting the extension and retraction path of the spring.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0017] This utility model embodiment provides a motor with heat dissipation function, such as Figure 1-4As shown, the motor with heat dissipation function includes: a motor body 1, on which an extension shaft 6 for outputting power is provided; a protective shell 2 sleeved on the motor body 1 for isolating the heat dissipation space, the extension shaft 6 being rotatably connected to the protective shell 2 and extending to the outside of the protective shell 2; vents 3 provided on both sides of the protective shell 2 for providing airflow channels to assist in heat dissipation of the motor body 1; a first protective cover 4 and a second protective cover 5 respectively sleeved on both sides of the protective shell 2 for closing the two vents 3, both the first protective cover 4 and the second protective cover 5 being provided with dustproof nets 10; and a connecting cylinder 7 fixedly sleeved on the extension shaft 6, the connecting cylinder 7 being provided with fan blades.

[0018] In this embodiment, the protective shell 2 serves to isolate the heat dissipation space, reducing interference from the external environment on the motor body 1 and providing support for the arrangement of the heat dissipation structure. The vent 3 provides a channel for airflow, assisting the motor body 1 in heat dissipation and accelerating heat dissipation. The dustproof nets 10 on the first protective cover 4 and the second protective cover 5 prevent dust from entering the motor and avoid dust affecting the motor's performance and lifespan. The connecting cylinder 7 and fan blades, which are fixedly sleeved outside the extension shaft 6, enable the extension shaft 6 to drive the fan blades to rotate when the motor is running, actively promoting airflow and improving heat dissipation efficiency, thus meeting the requirements for long-term stable and efficient operation of the motor.

[0019] In a further preferred embodiment of the present invention, a fixing plate 11 is fixed on the inner wall of the protective shell 2, a spring 12 is installed on the fixing plate 11, and a locking block 13 for extending to the outside of the protective shell 2 is fixed on the spring 12. The fixing plate 11, the spring 12 and the locking block 13 are all arranged in groups. The first protective cover 4 and the second protective cover 5 are both provided with a slot for accommodating the locking block 13.

[0020] In this embodiment, a fixing plate 11 is provided on the inner wall of the protective shell 2, providing a stable mounting base for the spring 12. The spring 12, mounted on the fixing plate 11, provides elastic support. The locking block 13 fixed on the spring 12 can extend to the outside of the protective shell 2. The fixing plate 11, spring 12, and locking block 13 are arranged in a group. Together with the locking slots on the first protective cover 4 and the second protective cover 5, the installation and removal of the protective cover are more convenient. When the protective cover needs to be installed, the locking block 13 is locked into the locking slot under the action of the spring 12, which plays a fixing role. When disassembling, only external force needs to be applied to make the locking block 13 disengage from the locking slot, which improves maintenance efficiency and also ensures the stability of the protective cover installation.

[0021] In a further preferred embodiment of the present invention, the second protective cover 5 is provided with an opening for providing an output channel for the extension shaft 6, and a flange 8 for connecting an external device is fixed on the extension shaft 6, with a buffer pad provided on the side of the flange 8 away from the extension shaft 6.

[0022] In this embodiment, by providing an opening on the second protective cover 5 to provide an output channel for the extension shaft 6, the extension shaft 6 can smoothly extend out of the protective shell 2 and connect to the external device, ensuring the smooth transmission of motor power. By fixing the flange 8 on the extension shaft 6, a stable connection to the external device is achieved, facilitating reliable docking of the motor with various devices. By setting a buffer pad, a buffering and shock-absorbing effect can be achieved when the motor vibrates during operation, reducing the impact of vibration on the external device and also reducing the damage to the motor caused by vibration feedback from the external device.

[0023] In a further preferred embodiment of the present invention, a support frame 9 connected to the outer wall of the motor body 1 for supporting the motor body 1 is fixed on the inner wall of the protective shell 2. An arc-shaped plate for increasing the contact area with the motor body 1 is installed on the support frame 9. A base 15 for supporting the protective shell 2 is fixed at the bottom of the protective shell 2.

[0024] In this embodiment, a support frame 9 connected to the outer wall of the motor body 1 is provided on the inner wall of the protective shell 2, which plays a role in stabilizing and supporting the motor body 1, effectively reducing the shaking generated during motor operation and improving operational stability. The arc plate installed on the support frame 9 increases the contact area with the motor body 1, making the support more uniform and reliable, further enhancing the stability of the motor body 1. The base 15 fixed at the bottom of the protective shell 2 provides a solid support foundation for this device, ensuring that the motor remains stable during placement and use and is not easily tipped over.

[0025] In a further preferred embodiment of the present invention, a connecting rope 16 is installed on the outer wall of the protective shell 2, and a push rod 17 is installed on the connecting rope 16 for inserting into the bayonet to abut against the bayonet block 13. The push rod 17 is provided with an adjustment block for providing an operating grip point, and an elastic pad 18 is installed on the outer wall of the protective shell 2 for contacting the push rod 17 to reduce shock and noise.

[0026] In this embodiment, by installing a connecting rope 16 on the outer wall of the protective shell 2, a flexible connection method is provided for the push rod 17, which facilitates the use and operation of the push rod 17. The push rod 17 on the connecting rope 16 can be inserted into the bayonet to abut against the latch 13, so that when disassembling the first protective cover 4 or the second protective cover 5, there is no need to press the latch 13 with effort, making the operation more convenient and labor-saving. The adjustment block set on the push rod 17 provides a gripping point for operation, further improving the convenience of operation. By installing an elastic pad 18 on the outer wall of the protective shell 2 to contact the push rod 17, it can play a role in shock absorption and noise reduction, reducing the noise generated by collision.

[0027] In a further preferred embodiment of the present invention, the spring 12 is provided with a limiting telescopic rod 14 for limiting the extension and retraction path of the spring 12. The limiting telescopic rod 14 is fixed on the fixing plate 11 and connected to the locking block 13. The limiting telescopic rod 14 consists of an outer cylinder 19 fixed on the locking block 13 and an inner rod 20 slidably installed in the outer cylinder 19 and connected to the fixing plate 11.

[0028] In this embodiment, by setting a limiting telescopic rod 14 inside the spring 12, it plays a key role in limiting the extension and retraction path of the spring 12, ensuring that the spring 12 maintains a stable movement trajectory during the extension and retraction process, avoiding bending or deviation of the spring 12 due to uneven force, and improving the reliability and stability of the spring 12. The limiting telescopic rod 14 is composed of an outer cylinder 19 and an inner rod 20, which allows the limiting telescopic rod 14 to slide flexibly with the extension and retraction of the spring 12, ensuring the limiting function without hindering the normal extension and retraction of the spring 12.

[0029] In a further preferred embodiment of the present invention, a sliding groove is provided on the inner wall of the outer cylinder 19, and a limiting block 21 connected to the inner rod 20 is slidably installed in the sliding groove. The sliding groove and the limiting block 21 are used to prevent the inner rod 20 from detaching from the outer cylinder 19.

[0030] In this embodiment, by setting a groove on the inner wall of the outer cylinder 19 and slidingly installing a limiting block 21 connected to the inner rod 20, an effective anti-detachment protection is achieved. When the inner rod 20 slides inside the outer cylinder 19, the limiting block 21 moves synchronously in the groove. The groove provides a clear movement track for the limiting block 21, which can prevent the inner rod 20 from detaching from the outer cylinder 19 due to excessive movement during the extension and retraction process.

[0031] In a further preferred embodiment of this utility model, a shock-absorbing pad is installed at the bottom of the base 15, the outer shell of the motor body 1 is made of brass, and the inner and outer walls of the outer shell of the motor body 1 are coated with an insulating coating. The connecting cylinder 7 and the fan blades are both made of polypropylene plastic.

[0032] In this embodiment, by installing shock-absorbing pads at the bottom of the base 15, the vibration energy generated during motor operation is effectively absorbed, reducing the impact of motor vibration on the installation foundation. At the same time, it reduces the interference of external vibration feedback on motor stability, making the motor run more smoothly. The brass material has good thermal conductivity, which helps the heat inside the motor to be quickly conducted to the surface of the outer casing for dissipation. By spraying an insulating coating on the inner and outer walls of the outer casing, the insulation performance of the motor is enhanced, preventing leakage accidents and ensuring safe use. The polypropylene plastic material is not only lightweight, which can reduce the load when the motor is running, but also has corrosion resistance, which can extend the service life of components.

[0033] In summary, compared with related technologies, this device isolates the heat dissipation space by setting up a protective shell 2 to provide support for the heat dissipation structure, assists heat dissipation by setting up a vent 3, prevents dust by using the dustproof nets 10 of the first protective cover 4 and the second protective cover 5, actively promotes airflow and improves heat dissipation efficiency by setting up a connecting cylinder 7 and fan blades, and uses a fixing plate 11, spring 12 and a locking block 13 fixed on the inner wall of the protective shell 2 in conjunction with the locking slots set on the protective cover to not only stabilize the protective cover, but also facilitate the disassembly of the protective cover.
