Description

Technical Field

[0001] The utility model relates to the field of security, in particular to a driving device and a special rolling shutter door for a silver pavilion. Background Art

[0002] Rolling shutter doors are made of multi-jointed door panels connected in series. The doors rotate up and down around the scroll above the door in a fixed slide. Rolling shutter doors are commonly used in shops, supermarkets, shopping malls, banks and other occasions.

[0003] Among them, rolling shutters are also needed in silver kiosks. Due to the particularity of silver kiosks, they have higher requirements for security, and their strength requirements are higher than ordinary rolling shutters. However, its overall structure is not much different from conventional rolling shutters. In the silver kiosk, if some special circumstances occur, the rolling shutters will be quickly released to quickly close the silver kiosk. Among them, in order to realize the retraction and extension of the rolling shutters, motors are used to drive the retraction and extension of the rolling shutters. Since the rolling shutters are heavy, a combination of motors and reducers will be used. This structure can be driven by low-power motors as much as possible. However, due to the existence of the reducer, the speed of the rolling shutters is relatively slow when they are rolled up or unrolled. If the rolling shutters are unrolled quickly, the reducer will be damaged. If the reducer is not used, although the output shaft of the motor can rotate when the rolling door is released, thereby realizing the rapid release of the rolling door, it is difficult for a simple ordinary motor to drive the heavy rolling door to rewind.

[0049] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0050] Example 1: See Figures 1 to 9 As shown, a driving device comprises a driving connection disk 119, a driving mechanism and a clutch mechanism, wherein the clutch mechanism is disposed between the driving connection disk 119 and the driving mechanism, and the driving mechanism is configured to drive the clutch mechanism to rotate;

[0051] The clutch mechanism includes a clutch disk 41 and at least one electromagnet 42 mounted on the clutch disk 41. The driving mechanism is configured to drive the clutch disk 41 to rotate. The clutch disk 41 is coaxially arranged with the driving connection disk 119, and the clutch disk 41 is arranged beside the driving connection disk 119.

[0052] The electromagnets 42 are disposed beside the axis of the clutch disc 41, and each of the electromagnets 42 is connected to the clutch disc 41 via a pushing assembly 43;

[0053] When the electromagnet 42 is energized, the magnetic force of the electromagnet 42 drives the electromagnet 42 to move toward the drive connection disk 119 and is adsorbed and connected to the drive connection disk 119. The drive mechanism can synchronously drive the drive connection disk 119 to rotate through the clutch mechanism.

[0054] When the electromagnet 42 is powered off, the pushing assembly 43 pushes the electromagnet 42 to move and separate from the driving connection disk 119 .

[0055] See also Figure 4 , 5 As shown, the utility model also provides a special rolling door for silver pavilions, including a rotating shaft 115 and a door body 11 connected to the rotating shaft 115, and the two ends of the rotating shaft 115 are respectively rotatably mounted on a column 116;

[0056] It also includes the above-mentioned driving device, and the driving connecting disk is installed at one end of the rotating shaft 115.

[0057] In this embodiment, the top of the door body is connected to the rotating shaft, and when the rotating shaft rotates, the door body is unrolled and reeled, that is, the rolling door is opened or closed. Among them, when it is necessary to drive the rolling door to open, the electromagnet is energized. When the electromagnet is energized, it has magnetism. The driving clutch disk is made of metal material, which is a material that can be adsorbed by a magnet. After the electromagnet is energized, the position of the driving connection disk is relatively immobile relative to the clutch disk, because the electromagnet will move toward the driving connection disk. Taking the direction shown in the figure as an example, the electromagnet moves to the right, so that the electromagnet is adsorbed on the driving connection disk, and a firm connection between the electromagnet and the driving connection disk is achieved. Since the electromagnet is connected to the clutch disk through the pushing assembly, the connection between the clutch disk and the driving connection disk is achieved. At this time, the driving mechanism works, and when the clutch disk is driven to rotate, it will synchronously drive the driving connection disk to rotate through the electromagnet and the clutch disk. When the driving connection disk rotates, it also drives the rotating shaft to rotate. When the rotating shaft rotates, it drives the door body to be reeled by the rotating shaft, thereby realizing the opening of the rolling door. If the door body needs to be unrolled, that is, when the rolling door is closed, the electromagnet is powered off. After the electromagnet is powered off, the electromagnet loses its magnetism. Due to the existence of the pushing component, the pushing component will drive the electromagnet away from the drive connection disk, that is, the electromagnet moves to the left and separates from the drive connection disk. The drive connection disk is no longer subject to the suction of the electromagnet and is not restricted by it. Due to the deadweight of the door body, it will unroll quickly. When the door body is unrolled, the shaft and the drive connection disk will rotate quickly, thereby realizing the rapid closing of the rolling door, and it will not be transmitted to the driving mechanism. In this way, the driving mechanism does not require super high power and super large size, and the cost is low and the space occupied is small. Furthermore, the power supply voltage of the electromagnet adopts 24V, which is a safe voltage, which is safer and prevents safety hazards in the event of leakage.

[0058] See also Figure 1 , 3 As shown in FIGS. 4 and 5 , a stop assembly 6 is further provided above the driving connection disk 119, and the stop assembly 6 includes a stop rod 61, a stop pin 62 and a pulling mechanism 63. A stop notch 64 is provided on the outer surface of the driving connection disk 119, and a first end of the stop rod 61 is rotatably connected to an external connecting member 65, and a second end of the stop rod 61 is arranged directly above the driving connection disk 119, and the stop pin 62 is installed on the second end of the stop rod 61, and the stop pin 62 is arranged directly above the driving connection disk 119;

[0059] The top of the pulling mechanism 63 is connected to the external connecting member 65 , and the other end of the pulling mechanism 63 is connected to the second end of the stop rod 61 .

[0060] When the pulling mechanism 63 applies a pulling force to the stop rod 61, the second end of the stop rod 61 and the stop pin 62 are driven to move upward and away from the driving connection plate 119;

[0061] When the pulling mechanism 63 releases the pulling force of the stop rod 61 , the second end of the stop rod 61 automatically descends under the weight, so that the stop pin 62 abuts against the top outer surface of the driving connection disk 119 or is stuck in the stop notch 64 .

[0062] In the utility model, after the rolling door is fully opened, that is, after the door body is fully rolled into place, the driving mechanism will stop working. If it is necessary to maintain the restriction on the driving connection disk to prevent the rotating shaft from rotating and causing the door body to be released, it is necessary to keep the electromagnet energized, which consumes a lot of energy. Therefore, by setting a stop assembly, after the rolling door is opened and reaches a predetermined position, the stop gap will face the stop pin, and then the pulling mechanism releases the pulling force on the stop rod, the stop rod is loaded and automatically drops, and the stop pin will be stuck in the stop gap, thereby achieving the limit of the driving connection disk. Among them, in this embodiment, the first end of the stop rod is at the rear side of the driving connection disk, and the first end is directly behind the stop gap. When the pulling mechanism does not give the stop rod a pulling force, the second end of the stop rod is loaded and automatically drops, and the stop pin is stuck in the stop gap. At this time, the stop rod is basically parallel to the horizontal plane. The first end of the stop rod is rotatably connected to the external connecting member, and the first end has a strip groove for rotatably connecting to the external connecting member, and can also move relatively a little bit, so as to give it some space to move and rotate. Because the pulling mechanism is located directly above the driving connection disk, when the pulling mechanism pulls the second end of the stop rod upward, if the position of the first end is fixed, it cannot rotate. Therefore, a strip groove structure is adopted. When the second end of the stop rod rises, it will also move forward a little bit, giving the stop rod space to move and rotate. After the rolling door is rolled into place, the pulling mechanism releases the pulling force, the second end of the stop rod is lowered under the weight, and the stop pin is stuck in the stop notch, and then the electromagnet is powered off. When the door body is lowered under the weight, the drive connection disk and the rotating shaft are prevented from rotating due to the restriction of the stop pin. In this way, there is no need to keep the electromagnet powered on, and the energy consumption is low. At the same time, the mechanical limit of the stop pin is adopted, which is safer. In this embodiment, when the door body is unrolled, the top outer surface of the rotating shaft rotates toward the front, and the first end is at the rear end of the rotating shaft, that is, in the relative direction of rotation. When the door body wants to be released, when the stop notch gives the stop pin a pulling force, the external connecting member will pull the driving connection disk through the stop rod and the stop pin, thereby achieving the limit. When the door body needs to be quickly lowered, the pulling mechanism gives the second end of the stop rod an upward pulling force, so that the stop pin moves upward and disengages from the stop notch. In this way, after the limiting force on the driving connection disk is lost, the deadweight of the door body is quickly lowered, and at the same time, the rotating shaft and the driving connection disk also rotate, thereby achieving the rapid release of the rolling door.

[0063] In the utility model, the external connecting member may be a mounting component of the rolling door, or may be a wall or other fixing mechanism.

[0064] In this embodiment, the pulling mechanism is an electromagnetic pull rod and a connecting rope. The bottom of the electromagnetic pull rod is connected to the second end of the stop rod through the connecting rope. When the electromagnetic pull rod is energized, it will be controlled to drive the second end of the stop rod to rise. When the electromagnetic pull rod is powered off, the second end of the stop rod loses tension, the stop rod will automatically drop, and the stop pin will abut against the top outer surface of the drive connection disk or the stop notch. In the utility model, the stop notch is L-shaped, and the two ends are respectively connected to the outer surface of the drive connection disk. If the second end of the stop rod drops, the stop pin abuts against the outer surface of the drive connection disk. When it is not in the stop notch, the electromagnet is powered off, the door body drops, and the rotating shaft and the drive connection disk are pulled to rotate. During the rotation process, the stop pin always abuts against the outer surface of the drive connection disk. When the stop notch rotates to face the stop pin, the stop pin is inserted into the stop notch, thereby realizing the limit of the drive connection disk. Among them, in this embodiment, in order to prevent the driving connection disk from sliding in contact with the stop pin when rotating, the stop rod is a U-shaped structure with an open bottom, and its bottom has a U-shaped groove 66. The middle part of the stop pin is in the U-shaped groove. A roller sleeve 67 is provided on the outside of the stop pin. The rolling sleeve is in the U-shaped groove. The width of the U-shaped groove is greater than the thickness of the missing connection disk. In this way, the roller sleeve will contact the outer surface of the driving connection disk. Even if the driving connection disk rotates, it will roll with the driving connection disk through the roller sleeve to prevent scratches. At the same time, when the rolling door is unrolled quickly, when the pulling mechanism gives the second end of the stop rod an upward pulling force, the roller sleeve and the stop notch are in rotational contact, so that the pulling force required by the pulling mechanism will be smaller, ensuring the smoothness of the pulling (due to the deadweight of the door body, the driving connection disk gives a relatively large thrust to the stop pin through the stop notch. If the roller sleeve is not provided, the pulling mechanism needs to spend a large force to pull the stop pin out of the stop notch).

[0065] See also Figure 2 As shown, the clutch disk 41 is provided with at least one through slot 410 matching the number of the electromagnets 42, and both ends of the through slot 410 penetrate the left end face and the right end face of the clutch disk 41. The middle part of each electromagnet 42 is inserted into one of the through slots 410, and the outer wall of the electromagnet 42 does not contact the inner wall of the through slot 410, thereby ensuring the smoothness of the movement of the electromagnet.

[0066] In this embodiment, there are four groups of electromagnets, and multiple groups of electromagnets are arranged outside the axis of the clutch disk. There are also four groups of through grooves. The four groups of electromagnets can effectively ensure the firmness of the direct adsorption of the electromagnets and the drive connection disk, and ensure that when the drive mechanism drives the drive connection disk to rotate through the clutch mechanism, the electromagnet will not fail to absorb the drive connection disk, thereby ensuring the safety of use. Of course, according to the size and weight of the rolling door, the number of electromagnets can be adjusted to ensure the firmness and quality of adsorption, and prevent the electromagnet and the drive connection disk from failing to absorb and slipping during the rolling process of the rolling door, thereby ensuring the safety of the rolling door.

[0067] See also Figure 1 , 2 As shown in , 5, the clutch disk 41 is arranged between the pushing assembly 43 and the driving connection disk 119, and the pushing assembly 43 includes an electromagnet mounting plate 431 and at least two pushing connectors, one end of the pushing connector is connected to the clutch disk 41, and the other end of the pushing connector is arranged away from the clutch disk 41;

[0068] The electromagnet mounting plate 431 is arranged opposite to the through slot 410, and the electromagnet mounting plate 431 is movably connected to the pushing connecting member. The middle part of the electromagnet 42 is arranged in the through slot 410, one end of the electromagnet 42 passes through the through slot 410 and is arranged opposite to the driving connecting disk 119, and the other end of the electromagnet 42 passes through the through slot 410 and is connected to the electromagnet mounting plate 431.

[0069] The push connecting member includes a push rod 432 and a push spring 433. One end of the push rod 432 is connected to the clutch plate 41, and the other end of the push rod 432 is provided with a positioning rod head 434.

[0070] The electromagnet mounting plate 431 is provided with a guide hole 435 matching the push rod 432, and the electromagnet mounting plate 431 is movably connected to the push rod 432 through the guide hole 435; each of the push rods 432 is respectively sleeved with a group of the push springs 433, and the two ends of the push springs 433 are respectively against the clutch disk 41 and the electromagnet mounting plate 431; the push springs 433 give a thrust to push the electromagnet mounting plate 431 and the electromagnet 42 away from the drive connection disk 119;

[0071] The push rod 432 is arranged parallel to the side of the axis of the clutch disc 41 .

[0072] In the utility model, there are two push connectors, which are symmetrically arranged on both sides of the through groove. The electromagnet mounting plate is directly connected to the push rod for movement. The push spring will always be in a compressed state, which will push the electromagnet mounting plate to move to the left. When the electromagnet mounting plate moves to the left, it will drive the electromagnet to move to the left synchronously, so that it is separated from the drive connection disk. Therefore, after the electromagnet is powered off, due to the loss of suction, the push spring pushes the electromagnet to move to the left, and the drive connection disk is quickly separated. The positioning rod head is set, and the diameter of the positioning rod head is greater than the diameter of the guide hole. After the push spring pushes the electromagnet mounting plate to move to a certain position to the left, it will be restricted by the positioning rod head, so that the moving position of the electromagnet is limited. In this way, when the electromagnet is not powered on, the distance between the electromagnet and the drive connection disk is relatively small, but they will not touch each other. After the electromagnet is powered on, the suction of the electromagnet can overcome the elastic force of the push spring, so that the electromagnet moves to the right and contacts and adsorbs the drive connection disk.

[0073] In this embodiment, the push rod adopts a bolt, and the right end of the bolt is threadedly connected to the clutch disk to achieve connection and fixation with the clutch disk. The positioning rod head adopts a nut, or a combination of a nut and a gasket. Furthermore, if the push rod adopts a bolt, its outer surface will have an external thread. When the guide hole of the electromagnet mounting plate is connected to the push rod, the sliding will not be smooth. Therefore, a sleeve 436 is provided on the outside of the push rod, and the push spring is sleeved on the outside of the sleeve. The electromagnet mounting plate is movably connected to the sleeve through the guide hole. In this way, it can be ensured that the electromagnet mounting plate can move stably axially relative to the push rod and will not be stuck by the external thread. Among them, the guide hole matches the sleeve.

[0074] See also Figure 1 , 4 As shown, the driving mechanism includes a motor assembly 44 and a transmission shaft 45. The motor assembly 44 is configured to drive the transmission shaft 45 to rotate. One end of the transmission shaft 45 is connected to the motor assembly 44. The clutch disc 41 is installed at the other end of the transmission shaft 45, and the clutch disc 41 is coaxially arranged with the transmission shaft 45. The motor assembly 44 includes a combination of a motor and a reducer. The end of the transmission shaft is connected to the output shaft of the reducer, and the motor drives the transmission shaft to rotate through the reducer. A mechanism is also provided to support the transmission shaft and the motor assembly, such as an extension plate to support the motor assembly, and a bearing and a bearing seat to support and reinforce the transmission shaft.

[0075] See also Figure 1 , 4 As shown, the transmission shaft 45 is further provided with a conductive ring 46, the conductive ring 46 is installed on the transmission shaft 45 via an insulating spacer 47, the conductive ring 46 is arranged between the motor assembly 44 and the clutch disc 41, and the electromagnet 42 is connected to the conductive ring 46 via a line;

[0076] In this embodiment, there are two conductive rings, and the neutral wires of all electromagnets are connected in parallel as one strand, and the live wires are also connected in parallel as one strand, the live wire is connected to a conductive ring, and the neutral wire is connected to a conductive ring, and the electromagnet is powered by the conductive ring to ensure normal power supply to the electromagnet when the clutch disc rotates. The insulating spacer prevents the conductive ring from being electrically connected to the transmission shaft.

[0077] In order to realize power supply to the conductive ring and ensure that no winding occurs during the rotation process, a carbon brush 48 is provided in contact with the outer surface of the conductive ring 46, and the conductive ring 46 is connected to the power supply through the carbon brush 48. There are two carbon brushes, which are in sliding contact with the two conductive rings respectively. When the transmission shaft rotates, the conductive ring will also rotate. When the conductive ring rotates, the power supply supplies power to the corresponding conductive ring through the carbon brush, thereby realizing normal power supply to the electromagnet.

[0078] Furthermore, in order to improve the safety of the electric rolling shutter door during the rolling process and prevent slipping or loose adsorption during the contact between the electromagnet and the drive connecting disk, a positioning component matching the number of the electromagnets is provided on the drive connecting disk, and each positioning component is arranged opposite to an electromagnet.

[0079] Through the setting of the positioning component, after the electromagnet is energized, the electromagnet will not only adsorb to the drive connecting disk, but will also be mechanically limited by the positioning component. In this way, after the adsorption force of the electromagnet on the drive connecting disk is connected, when the driving mechanism drives the drive connecting disk to rotate, if there is relative sliding between the electromagnet and the drive connecting disk (slipping), the electromagnet will also be limited by the positioning component to ensure that the electromagnet can normally drive the drive connecting disk to rotate with the clutch disk, thereby ensuring safety and stability in use.

[0080] Among them, the positioning component is a positioning groove 401 or a positioning block 402. When the positioning component is a positioning groove, when the electromagnet is energized, the electromagnet is adsorbed on the inner wall of the positioning groove. In this way, even if the electromagnet and the drive connecting disk slip, after slipping a certain distance, the side wall of the electromagnet will abut against the side wall of the positioning groove to achieve mechanical rotation limit of the two, ensuring that when the clutch disk rotates, the drive connecting disk also rotates normally.

[0081] When the positioning component is a positioning block, for example, when the rolling door is rolled up, the drive connecting disk needs to rotate counterclockwise, and the positioning block is in the counterclockwise direction of the electromagnet. Even if the electromagnet and the drive connecting disk slip, the side of the electromagnet will contact the positioning block to achieve mechanical rotation limit of the electromagnet and the drive connecting disk, ensuring that when the clutch disk rotates, the drive connecting disk also rotates normally.

[0082] In the description of the present invention, it should be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. In the description of the present invention, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0083] In the present utility model, unless otherwise clearly specified and limited, the terms "install", "connect", "connect", "fix" and the like should be understood in a broad sense, for example, it can be a fixed connection, or a detachable connection, or an integral one; it can be a mechanical connection, or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, for example, the two can form a mechanical abutment or abutment connection through abutment, contact, etc., the two can also be directly hung or hung through an intermediate medium, etc., or it can be the internal connection of the two elements or the interaction relationship between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
