Description

Technical Field

[0001] This utility model relates to the field of linear motor technology, and in particular to a high-efficiency heat dissipation linear motor. Background Technology

[0002] A linear motor is an electromagnetic drive device that directly converts electrical energy into linear motion. It breaks through the limitations of traditional rotary motors that convert rotational motion into linear motion through mechanical structures. It has advantages such as high response speed, high precision, and low wear, and is a core drive technology in the field of high-end automation.

[0003] For example, patent application number 202410325697.3 published on the China Patent Network, entitled "Linear Motor," includes a housing with a receiving cavity, a vibration unit placed within the receiving cavity, a drive unit, and elastic elements disposed on both sides of the vibration unit. The vibration unit includes a mass block and a mover fixed to the mass block. The drive unit is one of a coil and a magnet assembly, and the mover is the other of the coil and magnet assembly. Foam damping is connected between the mass block and the elastic elements. The foam damping includes a local melting point. By heating and melting the local melting point, the foam damping is bonded to the mass block and / or the elastic elements. The linear motor of this invention achieves bonding between the foam damping and the elastic elements and / or the mass block by heating the foam damping at a fixed point and relying on the adhesiveness of the foam damping after melting. This replaces the foam glue application in related technologies, saves Z-axis space, and effectively prevents glue from overflowing to other parts and affecting the assembly process of the linear motor, thereby improving the vibration performance of the linear motor.

[0004] However, the existing linear motors have a relatively simple structure, relying only on internal cooling fans to guide airflow and dissipate heat, which cannot fully utilize the power during movement and affects energy consumption. Utility Model Content

[0005] The purpose of this invention is to solve the problem of the single heat dissipation method in the existing technology, and to propose a high-efficiency heat dissipation linear motor.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

The outer surface of the transmission wheel contacts the side of the guide rail, and the transmission wheel and the vortex fan are driven by a speed-changing structure.

[0008] As a preferred technical solution of this application, the transmission structure includes an extension plate fixedly connected to the surface of the connecting block.

[0012] As a preferred technical solution of this application, a rubber pad is fixedly connected to the outer surface of the transmission wheel, the outer surface of the rubber pad is in contact with the surface of the guide rail, and the rubber pad is elastic.

[0013] Compared with the prior art, this utility model provides a high-efficiency heat dissipation linear motor, which has the following beneficial effects:

[0014] 1. This high-efficiency heat-dissipating linear motor converts the linear kinetic energy generated during motor movement into rotational kinetic energy through direct contact friction between the transmission wheel and the side of the guide rail, thus avoiding additional energy consumption.

[0015] 2. This high-efficiency heat-dissipating linear motor uses a first-stage gear to increase the low-speed rotation of the transmission wheel to the medium speed of the transmission rod, and a second-stage gear to further amplify the speed, enabling the vortex fan to achieve a higher speed.

[0016] 3. This high-efficiency heat-dissipating linear motor uses a triangular support structure formed by combining a vertical plate and bolts to enhance the rigidity of the connecting block and the motor body, thus preventing structural loosening caused by high-frequency vibration.

[0017] 4. This high-efficiency heat dissipation linear motor guides airflow directly to the motor body surface through the opening inside the shield, and the top opening accelerates the exhaust of hot air, forming a directional circulation of cold air intake and hot air exhaust.

[0018] 5. This high-efficiency heat-dissipating linear motor reduces airflow vortex at the opening through the guide plate, thereby reducing wind resistance loss.

[0019] 6. This high-efficiency heat-dissipating linear motor uses a rubber pad to elastically deform and buffer the impact caused by uneven guide rails, reducing transmission noise. Moreover, the elastic material increases the coefficient of friction, ensuring that the transmission wheel can still rotate reliably when moving at low speeds. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0026] Example 1:

[0027] Reference Figure 1-4A high-efficiency heat-dissipating linear motor includes a guide rail 1, a motor body 2 connected to the surface of the guide rail 1, connecting blocks 3 on both sides of the motor body 2, a vortex fan 4 movably connected to the top of the connecting blocks 3 via bearings, and a transmission wheel 5 movably connected to the bottom of the connecting blocks 3 via bearings. The outer surface of the transmission wheel 5 contacts the side of the guide rail 1, and the transmission wheel 5 and the vortex fan 4 are connected by a speed-changing structure. Through the direct contact friction between the transmission wheel 5 and the side of the guide rail 1, the linear kinetic energy generated when the motor moves is converted into rotational kinetic energy, avoiding additional energy consumption. The speed-changing structure includes an extension plate 6 fixedly connected to the surface of the connecting blocks 3, a transmission rod 7 movably connected to the inside of the extension plate 6 via bearings, and a primary gear fixedly connected to the bottom end of the transmission rod 7 and the top of the transmission wheel 5. 8. The first-stage gears 8 mesh with each other. The bottom of the vortex fan 4 and the top of the transmission rod 7 are both fixedly connected to the second-stage gears 9, which mesh with each other. The two sides of the connecting block 3 are both fixedly connected to the vertical plates 10. Bolts 11 are inserted into the surface of the vertical plates 10. The inner end of the bolts 11 extends into the interior of the motor body 2 and is threadedly connected to the motor body 2. The top of the connecting block 3 is fixedly connected to the shield 12, which is fitted onto the surface of the vortex fan 4. The inner side and top of the shield 12 are provided with openings for airflow. The two ends of the inner side of the shield 12 are both fixedly connected to the guide plates 13, which are located on both sides of the openings. The outer surface of the transmission wheel 5 is fixedly connected to the rubber pad 14, which is in contact with the surface of the guide rail 1. The rubber pad 14 is elastic.

[0028] Specifically, during operation / use of this high-efficiency heat-dissipating linear motor: When the high-efficiency heat-dissipating linear motor starts moving on the guide rail 1, the motor body 2 drives the overall structure to move linearly along the guide rail 1 through electromagnetic thrust. At the same time, the connecting blocks 3 installed on both sides of the body drive the transmission wheel 5 at the bottom to contact the side of the guide rail 1. Since the outer surface of the transmission wheel 5 is fixed with an elastic rubber pad 14, it begins to rotate under friction, thereby converting the linear power of the motor movement into rotational kinetic energy. The rotation of the transmission wheel 5 is then transmitted upward through the speed-changing structure. The first-stage gears 8 mesh with each other, driving the transmission rod 7 to rotate. Subsequently, the second-stage gears 9 further mesh, amplifying the speed and driving the motor. The vortex fan 4 rotates at high speed, and the strong airflow generated by the vortex fan 4 forms a vortex in the shield 12 on the top of the connecting block 3. The opening of the shield 12 allows the airflow to flow efficiently from the inside and the top, while the inner guide plate 13 guides the airflow direction and concentrates it on the surface of the motor body 2 to achieve forced heat dissipation. Throughout the process, the connecting block 3 is firmly fixed to the motor body 2 by the upright plates 10 on both sides and the bolts 11 to ensure structural stability. The elastic design of the rubber pad 14 buffers the impact of movement and avoids slippage or damage. Once the motor stops moving, the heat dissipation automatically stops, but during operation, the system continuously recycles the waste power for cooling, significantly reducing the temperature rise and improving reliability and energy efficiency.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
