Abstract
Description
Technical Field
[0001] The utility model belongs to the field of rolling door motors, and more specifically, particularly relates to an anti-motor overheat control box for a rolling door motor. Background Art
[0002] A rolling door is composed of multiple movable plate bodies connected together. The opening and closing of the rolling door are controlled by a motor, and it rotates and retracts around the upper scroll. When in the retracted state, the rolling door can be better hidden and is applicable to many scenarios such as stores, shopping malls, garages, etc.
[0003] However, when the rolling door is repeatedly operated under overheat and overload of the motor, the internal components are prone to rapid wear due to overheating and other problems, and it is easy to cause equipment failure problems such as loose retraction and rapid loose rotation and descent of the rolling door during the use of the rolling door motor. Content of the Utility Model
[0004] In order to solve the above technical problems that when the rolling door is repeatedly operated under overheat and overload of the motor, the internal components are prone to rapid wear due to overheating and other problems, and it is easy to cause problems such as loose retraction and rapid loose rotation and descent of the rolling door during the use of the rolling door motor.
[0005] The purpose and effect of an anti-motor overheat control box for a rolling door motor of the present utility model are achieved by the following specific technical means:
[0006] Its structure includes a mounting plate, a chain, a runner, a rotating body, a motor, and a control end. The runner is fixedly installed on the surface of the mounting plate. The runner and the rotating body are of an integrated structure. The chain is connected between the runner and the motor. The control end is electrically connected to the motor;
[0007] The control end includes a limiting plate, a driving wheel, a magnetic body, a pressure-receiving body, a positive secondary block, a positive block, and a housing. The driving wheel is connected to the runner through a chain. The limiting plate and the magnetic body are of an integrated structure. The pressure-receiving body is installed between the limiting plate and the housing to receive force. A positive secondary block is installed at the end of the magnetic body. A positive block is provided on the side of the positive secondary block away from the magnetic body. After the positive block is energized, it will exert a repulsive and pushing effect on the positive secondary block.
[0008] Furthermore, the positive block includes a temperature-sensitive core, a connection box, a control box, and a transmission wire. The temperature-sensitive core penetrates into the motor and is connected to the connection box at the other end. The connection box is electrically connected to the control box. The transmission wire is connected between the control box and the positive block. The temperature-sensitive core is located inside the motor and can sense the internal temperature for conduction control.
[0009] Further, the magnetic attractor and the driving wheel have an attracting magnetic force. There are two pressure-receiving bodies made of soft material, which play a role in buffering and returning when stressed at the connection part. There are three temperature-sensitive cores installed vertically, which can evenly conduct the sensed temperature.
[0010] Further, the driving wheel includes a limiting layer, tooth heads, and a central shaft. The limiting layer and the central shaft are of an integrated structure. The tooth heads penetrate through the inside of the limiting layer, and the tooth heads are evenly distributed in a circular shape.
[0011] Further, each tooth head includes an extension sense, a suction-receiving head, a limiting block, a pulling-back body, and a connecting ring. The extension sense is installed between the suction-receiving head and the limiting block. The pulling-back body is attached to the inner surface of the limiting block, and the connecting ring is of an annular structure.
[0012] Further, the extension sense moves within the groove of the limiting layer. The pulling-back body and the connecting ring are of an integrated structure, and the suction-receiving head can move according to the suction force of the magnetic attractor.
[0013] Compared with the prior art, the present utility model has the following beneficial effects:
[0014] First, when the motor overheats, the temperature can be transmitted and sensed through the temperature-sensitive core, and the magnetism of the positive electrode block is turned on, so as to push out the magnetic attractor, adsorb and fix the position and rotation of the driving wheel for the chain, and prevent the situation of loose rotation caused by overheating of the motor.
[0015] Second, when the magnetic attractor adsorbs and jams the chain on the driving wheel and the tooth heads are in the extended state, the chain is in a static clamping state. When the motor continues to be at an overheated temperature, it cannot continue to work. It is necessary to cut off the power supply to make the control end lose power, and then the chain will be loosened. Through manual control, it is avoided that the motor continues to control and affects the internal device, resulting in the dangerous situation of the door body suddenly falling.

Specific embodiments
[0023] The following further describes the present utility model with reference to the accompanying drawings:
[0024] As shown in Figure 1 to Figure 6 the attached drawings:
[0025] The present utility model provides a control box for preventing overheating of a rolling - door motor, and its structure includes a mounting plate 1, a chain 2, a runner 3, a rotating body 4, a motor 5, and a control end 6. The runner 3 is fixedly installed on the surface of the mounting plate 1. The runner 3 and the rotating body 4 are of an integrated structure. The chain 2 is connected between the runner 3 and the motor 5. The control end 6 is electrically connected to the motor 5.
[0026] The control end 6 includes a limit plate 61, a driving wheel 62, a magnetic body 63, a pressure - receiving body 64, a positive - pole sub - block 65, a positive - pole block 66, and an outer shell 67. The driving wheel 62 is connected to the runner 3 through the chain 2. The limit plate 61 and the magnetic body 63 are of an integrated structure. The pressure - receiving body 64 is installed between the limit plate 61 and the outer shell 67 to receive force. A positive - pole sub - block 65 is installed at the end of the magnetic body 63. A positive - pole block 66 is provided on the side of the positive - pole sub - block 65 away from the magnetic body 63. After the positive - pole block 66 is electrified, it will exert a repulsive and pushing force on the positive - pole sub - block 65. The limit plate 61 limits the moving range of the overall connection part.
[0027] Among them, the positive - pole block 66 includes a temperature - sensing core 11, a connection box 12, a control box 13, and a transmission wire 14. The temperature - sensing core 11 penetrates the inside of the motor 5 and is connected to the connection box 12 at the other end. The connection box 12 is electrically connected to the control box 13. The transmission wire 14 is connected between the control box 13 and the positive - pole block 66. The temperature - sensing core 11 is located inside the motor 5 and can sense the internal temperature for conduction control. When the temperature value reaches a certain height, the control box 13 will energize the positive - pole block 66 through the transmission wire 14.
[0028] Among them, the magnetic attracting body 63 and the driving wheel 62 have an attracting magnetic force. There are two pressure-receiving bodies 64 made of soft material, which play a role of buffering and returning when stressed at the connection part. There are three temperature-sensitive cores 11 installed in the vertical direction, which can evenly conduct the sensed temperature. The outer surface of the magnetic attracting body 63 is an arc structure, which can be more closely contacted with the driving wheel 62.
[0029] Among them, the driving wheel 62 includes a limiting layer a1, tooth heads a2, and a central shaft a3. The limiting layer a1 and the central shaft a3 are of an integrated structure. The tooth heads a2 penetrate through the inside of the limiting layer a1. The tooth heads a2 are evenly distributed in a circular shape. The tooth heads a2 are stuck in the gaps of the chain 2 and rotate.
[0030] Among them, the tooth head a2 includes an extension sense 01, a suction-receiving head 02, a limiting block 03, a pulling-back body 04, and a connecting ring 05. The extension sense 01 is installed between the suction-receiving head 02 and the limiting block 03. The pulling-back body 04 is attached to the inner surface of the limiting block 03. The connecting ring 05 is of a circular ring structure. The pulling-back body 04 is of a rubber soft body structure, which can play a role of pulling and returning.
[0031] Among them, the extension sense 01 moves in the groove of the limiting layer a1. The pulling-back body 04 and the connecting ring 05 are of an integrated structure. The suction-receiving head 02 can move according to the suction force of the magnetic attracting body 63. When the central shaft a3 rotates, it will drive the limiting layer a1 and the tooth heads a2 to rotate together.
[0032] Specific usage method and function of this embodiment:
[0033] In the present utility model, the driving wheel 62 is controlled by the motor 5 to rotate, and the chain 2 drives the rotating wheel 3. The rolling shutter door will rotate together with the rotating body 4. When the motor 5 is in an overheated state, the temperature-sensitive core 11 inside the motor 5 transmits the temperature value to the control box 13 through the connection box 12. The control box 13 will transmit it to the positive electrode block 66 through the transmission wire 14. When the positive electrode block 66 is energized, it will generate a magnetic force, which forms a repulsive force between like poles with the positive electrode sub-block 65, and discharges and pushes the positive electrode sub-block 65. The limiting plate 61 and the magnetic attracting body 63, which are integrated, will be moved out together with the positive electrode sub-block 65. During the movement, the pressure-receiving body 64 is squeezed. The pressure-receiving body 64 plays a role of pressure buffering, so that the magnetic attracting body 63 can move to the outer ring of the driving wheel 62. The magnetic attracting body 63 will adsorb the suction-receiving head 02 of the tooth head a2. The extension sense 01 will move outwards along the groove of the limiting layer a1. The limiting block 03 limits the overall movement range. The pulling-back body 04 connected to the inside will be stressed and pulled to play a role of limiting and returning, so that one end of the tooth head a2 in contact with the chain 2 extends outwards by the suction force of the magnetic attracting body 63, positions the chain 2, and adsorbs to the magnetic attracting body 63 to fix the position of the chain 2.
[0034] Any technical solution that uses the technical solution of the present utility model or is designed by those skilled in the art inspired by the technical solution of the present utility model to achieve the above technical effects shall fall within the protection scope of the present utility model.
