[0002] Rolling shutter door is a series of multi-jointed door panels, which are driven by the motor. The rolling shutter door is in a fixed slideway, and the door rotates up and down with the reel above the door as the center. It is often used in public places or residences such as commercial storefronts, garages, shopping malls, hospitals, factories and mines, and rolling shutter door motors are motors used to drive the opening and closing of rolling shutter doors. It can realize the opening, closing, and stopping of rolling shutter doors through remote control or key operation.

[0003] Based on the above, during the use of the rolling door motor, it is usually connected to the three-proof control box of the motor, and the rolling door motor is controlled by the control box. However, although the existing three-proof control box can be anti-corrosion, waterproof and dustproof, there are many electronic components installed inside the control box. These electronic components will generate a lot of heat when running. The heat dissipation efficiency is slow because it only relies on the heat dissipation holes on one side of the control box. The slow temperature drop may cause damage to the internal electronic components. Utility Model Content

[0016] (1) The utility model relates to a three-proof control box for a rolling shutter door motor. A heat dissipation unit is provided on the inner side of the control box. The heat inside the control box is ventilated and dissipated by means of wind generated by the operation of a ventilation fan. When the ventilation fan is in operation, the U-shaped block and the mounting seat thereon are driven to rotate and reciprocate up and down, thereby driving the guide plate to rotate and swing reciprocally up and down through a pull rod. Since the guide plates are connected by a belt group, a plurality of guide plates are driven to swing synchronously, and the ventilation wind force generated by the operation of the ventilation fan is evenly blown to the interior of the control box, thereby evenly dissipating the heat and ventilating the interior of the control box, thereby avoiding the situation in which heat accumulation inside the control box due to slow heat dissipation causes damage to electronic components.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Example:

[0028] See also Figure 1-Figure 7 A three-proof control box for a rolling door motor comprises a control box 1, a heat sink 2 and a heat sink unit 3. A plurality of heat sinks 2 are installed on one side of the control box 1. The heat sink 2 is located on one side of the control box 1 and is provided with a heat sink unit 3 which can evenly dissipate heat inside the control box 1.

[0029] In this embodiment, the heat sink 2 includes a circular through hole 21, a strip groove 22 and a trapezoidal block 23. A circular through hole 21 is provided on one side of the heat sink 2 close to the heat dissipation unit 3. A plurality of strip grooves 22 capable of ventilating and dissipating heat for the control box 1 and the heat dissipation unit 3 are arrayed on the other side of the circular through hole 21. The tops of the plurality of strip grooves 22 are connected to trapezoidal blocks 23 capable of waterproofing the strip grooves 22.

[0030] In this embodiment, the trapezoidal block 23 can shield the strip groove 22 by virtue of its trapezoidal shape structure. When water drops onto the trapezoidal block 23 , it will flow down through the trapezoidal slope of the trapezoidal block 23 , preventing moisture or rainwater from flowing into the control box 1 through the strip groove 22 .

[0031] In this embodiment, the heat dissipation unit 3 includes a ventilation fan 31, a handle 32, an air collecting hood 33, a guide plate 34 and a belt group 35. The ventilation fan 31 is connected to the circular through hole 21 on the heat dissipation plate 2. A handle 32 is installed on one side of the ventilation fan 31. The handle 32 and the ventilation fan 31 are on the same center line. An air collecting hood 33 is connected to one side of the ventilation fan 31. The air collecting hood 33 is rotatably equipped with a plurality of guide plates 34 through a rotating shaft. The plurality of guide plates 34 are slidably equipped with a belt group 35 that can drive the plurality of guide plates 34 to rotate synchronously.

[0032] In this embodiment, the belt group 35 is composed of a first belt 351 and a second belt 352. The first belt 351 and the second belt 352 are alternately arranged and connected to the rotating shafts on a plurality of guide plates 34. When one group of guide plates 34 rotates, a group of belts connected thereto will be driven to operate through the rotating shaft, thereby driving the plurality of guide plates 34 to rotate synchronously with the help of a plurality of alternating belt groups 35.

[0033] In this embodiment, the handle member 32 includes a U-shaped block 321, a mounting seat 322, a pull rod 323 and a connecting seat 324. One end of the U-shaped block 321 is connected to the ventilation fan 31. The mounting seat 322 is rotatably engaged at the U-shaped groove of the U-shaped block 321. The bottom of the mounting seat 322 is connected to a pull rod 323. The other end of the pull rod 323 is rotatably engaged with the connecting seat 324. The connecting seat 324 is connected to a group of guide plates 34 at the bottom of the ventilation fan 31. When the U-shaped block 321 rotates, the pull rod 323 can drive the guide plates 34 connected thereto to swing back and forth. Under the connecting action of the belt group 35, several groups of guide plates 34 will swing back and forth together.

[0034] Working principle: When the three-proof control box of the rolling door motor is in use, the ventilation fan 31 is driven to generate wind to ventilate and dissipate the heat inside the control box 1, and the heat is discharged through the strip grooves 22 on the heat sink 2. When the ventilation fan 31 is running, it will drive the U-shaped block 321 connected thereto to rotate together. Since the U-shaped block 321 is rotatably connected with the mounting seat 322, the mounting seat 322 will reciprocate up and down following the rotation of the U-shaped block 321. Since the mounting seat 322 is connected to a group of guide plates 34 at the bottom of the gas collecting cover 33 through the pull rod 323 and the connecting seat 324, the guide plates 34 will be driven to rotate and swing up and down together with the mounting seat 322 and the pull rod 323;

[0035] Since several groups of guide plates 34 are connected by the first belt 351 and the second belt 352 on one side, when a group of guide plates 34 at the bottom rotates, the belt group 35 will drive several guide plates 34 to swing synchronously together, and the ventilation wind force generated by the operation of the ventilation fan 31 will be evenly blown to the inside of the control box 1, so as to evenly dissipate heat and ventilate the inside of the control box 1.
