[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.
[0023] The present utility model provides a technical solution: As Figure 1 , Figure 3 and Figure 4 shown, in this embodiment, a ventilation structure for a linear motor coil assembly includes a motor mover 1, and is characterized in that: on both sides of the bottom of the motor mover 1, an outer attached cover 2 is fixedly installed, and a ventilation component 5 is installed inside one of the outer attached covers 2. The ventilation component 5 includes a fan 504 fixedly installed at the bottom of the outer attached cover 2. The inner wall of the bottom of the outer attached cover 2 is fixedly connected with an intake pipe 501. The fan 504 is communicated with the internal space of the intake pipe 501. The intake pipe 501 is rotatably connected with an exhaust pipe 502 inside. A plurality of intake holes 503 are formed on the circumferential outer wall of the exhaust pipe 502. The plurality of intake holes 503 are all communicated with the internal space of the intake pipe 501. A plurality of equally spaced air outlet holes are arranged on the circumferential outer wall of the exhaust pipe 502.
[0024] When the fan 504 at the bottom of the outer attached cover 2 is started, the fan 504 sucks the external air into the intake pipe 501. Then, these airflows will enter the exhaust pipe 502 through the plurality of intake holes 503, and finally spray onto the surface of the coil inside the motor mover 1 from the plurality of nozzles of the exhaust pipe 502.
[0025] On one side of the circumferential outer wall of the air outlet pipe 502, a toothed ring 505 is fixedly sleeved. A driving strip 506 is slidably inserted into the inner wall of the bottom of the outer attachment cover 2. A rack adapted to the toothed ring 505 is arranged outside the driving strip 506. An extension block is arranged on the outer wall of one end of the driving strip 506, and a spring 507 is fixedly connected between the extension block and the inner wall of the bottom of the outer attachment cover 2.
[0026] A base 4 is sleeved outside the motor mover 1, and a plurality of stators adapted to the motor mover 1 are arranged inside the base 4.
[0027] A plurality of equally spaced bumps 509 are arranged on the inner wall of the bottom of the base 4, and the driving strip 506 can contact the bumps 509.
[0028] When the motor mover 1 moves, the driving strip 506 will also move synchronously with the driving strip 506. When the end 508 at its end contacts the bump 509, it will be gradually lifted by the bump 509. The rack of the driving strip 506 can drive the air outlet pipe 502 to flip through the toothed ring 505 engaged with it. Furthermore, the direction of the air flow will also change, so as to ensure that the area where the coil is blown is larger, thereby further improving the ventilation effect. Finally, it escapes to the outside from the air outlet holes 3 of the other outer attachment cover 2. As the motor mover 1 continues to move, the stretched spring 507 will be driven back to its original position, and so on.
[0029] As Figure 4 shown, one end of the bottom of the driving strip 506 is provided with an end 508, and the end 508 is circularly arranged, which can prevent the bump 509 from hindering the normal movement of the driving strip 506.
[0030] As Figure 2 shown, a plurality of equally spaced air outlet holes 3 are arranged in the middle of the other outer attachment cover 2, and the plurality of air outlet holes 3 are all communicated with the inner space of the motor mover 1, which can enable the hot air flow to be dissipated to the outside faster.
[0031] As Figure 1 and Figure 2 shown, both of the two outer attachment covers 2 are made of metal materials, so that the heat dissipation effect of the two is better.
[0032] The present utility model provides a ventilation structure for a linear motor coil assembly, and the specific working principle is as follows:
[0033] When the motor mover 1 is powered on, the fan 504 at the bottom of the outer cover 2 starts. The fan 504 sucks external air into the intake pipe 501. Then, these airflows will enter the outlet pipe 502 through multiple intake holes 503 and finally spray from the multiple nozzles of the outlet pipe 502 onto the surface of the coil inside the motor mover 1. When the motor mover 1 moves, the drive bar 506 will also move synchronously. When the end head 508 at its end contacts the convex block 509, it will be gradually lifted by the convex block 509. The rack of the drive bar 506 can drive the outlet pipe 502 to flip through the toothed ring 505 meshing with it. As a result, the direction of the airflow will also change, ensuring that the area of the coil being blown is larger, further improving the ventilation effect. Finally, it dissipates to the outside through the air outlet hole 3 of another outer cover 2. As the motor mover 1 continues to move, the stressed extension spring 507 will be driven back to its original position, and so on.
[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
