Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to a separation type electromagnetic clutch. Background Art

[0002] A disconnect electromagnetic clutch is a mechanical device widely used in automated equipment and vehicles, designed to achieve precise power control. Its primary function is to rapidly disconnect or reconnect the power source and load through electromagnetic principles, thereby controlling and transmitting power. The basic structure of a disconnect electromagnetic clutch typically includes an electromagnetic coil, a clutch disc, and its corresponding mechanical components. When current passes through the electromagnetic coil, the generated magnetic field tightly bonds the clutch disc to the drive shaft, transmitting power. Conversely, when power is removed, the connection between the clutch disc and the drive shaft is broken, interrupting power transmission.

[0003] When the existing electromagnetic clutch is in use, in order to protect its internal components, a protective shell is set on the outside. However, the form of the protective shell is relatively simple, which leads to deviation in its heat dissipation effect, so that the electromagnetic clutch cannot be cooled in a timely and effective manner, causing the electromagnetic clutch to be easily damaged. Therefore, this problem needs to be solved. Utility Model Content

[0004] The purpose of the utility model is to solve the shortcomings of the prior art and to propose a separation type electromagnetic clutch.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] 14. The heat dissipation device as claimed in claim 13, wherein the bridge has two opposite ends, and one end is connected to the other end of the bridge. The other end is connected to the bridge by a threaded connection, and the other end is connected to the bridge by a threaded connection. The bridge has two opposite ends, and the other end is connected to the bridge by a threaded connection.

[0007] As a further solution of the present invention, the heat dissipation mechanism includes a storage groove, which is opened on one side of the heat dissipation ring, and a fan is fixedly connected to the inside of the storage groove. A first vent is opened on the surface of the storage groove close to the main body, and a guide groove is opened on the end of the first vent close to the side of the main body, and the guide groove is opened in a ring shape. The second vent is opened on one side of the guide groove, and the first vent, the guide groove, and the second vent are arranged to be interconnected. The main body can be cooled by the setting of the fan.

[0008] As a further solution of the present invention, the moving mechanism includes four electric push rods, which are fixedly connected to the bottom of the main body. The bottom of the four electric push rods is fixedly connected to the same pull ring, and the first baffle is fixedly connected to the top of the pull ring. The pull ring is close to the fan side and is provided with a protective mechanism for protecting the fan. The first baffle can be moved by setting the electric push rod.

[0009] As a further solution of the present invention, the protection mechanism includes a second baffle, which is rotatably connected to one side of the storage slot, and the pull ring is fixedly connected to an extrusion plate on the top of the side close to the second baffle. The extrusion plate and the second baffle are arranged in cooperation with each other, and the second baffle is fixedly connected to the surface of the side close to the heat dissipation ring with three springs, and the other ends of the three springs are fixedly connected to one side of the heat dissipation ring. The fan can be protected by the setting of the second baffle.

[0010] The beneficial effects of the utility model are:

[0011] 1. The utility model accelerates the air flow rate around the heat sink through the vents, so that the main body can have a better heat dissipation effect, thereby effectively solving the problem that the protective shell is relatively single in form, which leads to deviation in its heat dissipation effect, so that the electromagnetic clutch cannot be cooled in time and effectively, causing the electromagnetic clutch to be easily damaged. When the second baffle is opened, the fan will move accordingly. A first vent is provided on one side of the fan, and the first vent is connected to the second vent through a guide groove. After the fan is started, the air flow rate on the surface of the heat sink can be accelerated, so that the heat sink can dissipate heat more quickly, and the air inlets of the first vent and the second vent are both larger than the air outlet, so that the air can be further cooled, so that the heat dissipation effect of the heat sink can be better.

Through the arrangement of the ventilation openings, the heat dissipation effect of the body 1 can be better.

[0021] Reference Figure 2 - Figure 4In a preferred embodiment, the heat dissipation mechanism includes a storage groove 201, which is opened on one side of the heat dissipation ring 2, and a fan 208 is fixedly connected to the inside of the storage groove 201. A first vent 202 is opened on the surface of the storage groove 201 close to the main body 1, and a guide groove 203 is opened at the end of the first vent 202 close to the side of the main body 1, and the guide groove 203 is opened in a ring shape, and the second vent 204 is opened on one side of the guide groove 203. The first vent 202, the guide groove 203, and the second vent 204 are arranged to penetrate each other. Through the arrangement of the fan 208, the main body 1 can be cooled.

[0022] Reference Figure 5 and Figure 6 In a preferred embodiment, the moving mechanism includes four electric push rods 301, which are fixedly connected to the bottom of the main body 1. The bottom of the four electric push rods 301 is fixedly connected to the same pull ring 3, and the first baffle 302 is fixedly connected to the top of the pull ring 3. The pull ring 3 is close to the fan 208 and is provided with a protective mechanism for protecting the fan 208. The first baffle 302 can be moved by the setting of the electric push rod 301.

[0023] Reference Figure 2 and Figure 5 In a preferred embodiment, the protection mechanism includes a second baffle 303, which is rotatably connected to one side of the storage groove 201, and an extrusion plate 305 is fixedly connected to the top of the pull ring 3 close to the second baffle 303. The extrusion plate 305 and the second baffle 303 are arranged in cooperation with each other. Three springs 304 are fixedly connected to the surface of the second baffle 303 close to the heat dissipation ring 2, and the other ends of the three springs 304 are fixedly connected to one side of the heat dissipation ring 2. The fan 208 can be protected by the setting of the second baffle 303.

[0024] From the above description, it can be seen that the above-mentioned embodiment of the present invention achieves the following technical effects: when the main body 1 needs to dissipate heat, the electric push rod 301 will start first, and a pull ring 3 is installed at the bottom of the electric push rod 301, so that when the electric push rod 301 is started, it will drive the pull ring 3 to reset, and a first baffle 302 is installed on the top of the pull ring 3, and three third vents 306 are opened on one side of the first baffle 302, and the three third vents 306 are all coordinated with the second vents 204 on one side of the heat dissipation ring 2, and the second vents 204 are initially blocked by the first baffle 302 to prevent dust and impurities from entering the interior of the heat dissipation ring 2, and when the pull ring 3 drives the first baffle 302 to move upward, the third vents 306 will overlap with the second vents 204, so that the second vents 204 can be ventilated normally, and an extrusion plate 305 is also installed on one side of the pull ring 3, and the extrusion plate 305 cooperates with the second baffle 303 When the second baffle 303 is rotated to one side of the heat dissipation ring 2, the extrusion plate 305 will squeeze the second baffle 303. Because the extrusion plate 305 is squeezed from one side of the second baffle 303, the second baffle 303 can be rotated during the squeezing process, thereby releasing the protection of the fan 208. When the second baffle 303 is opened, the fan 208 will move accordingly. A first vent 202 is provided on one side of the fan 208, and the first vent 202 is connected to the second vent 204 through the guide groove 203. After the fan 208 is started, the air flow rate on the surface of the heat dissipation plate 205 can be accelerated, so that the heat dissipation plate 205 can dissipate heat more quickly. In addition, the air inlets of the first vent 202 and the second vent 204 are both larger than the air outlet, so that the air can be further cooled, so that the heat dissipation effect of the heat dissipation plate 205 can be better.
