Description

Technical Field

[0001] The invention specifically relates to a bank rolling door. Background Art

[0002] Rolling shutters (rolling doors) are made of multi-jointed door panels connected in series, which rotate up and down in a fixed slideway around the scroll above the door. Rolling shutters are commonly used in shops.

[0003] The rolling door plays the same role as the wall in horizontal partitioning. It consists of curtain plate, seat plate, guide rail, support, reel, box, control box, rolling door machine, limiter, lintel, manual quick release switch device, button switch and safety device. The existing bank rolling door has a single function and consumes a lot of electricity, which leads to a waste of resources. Summary of the invention

[0004] Based on the above problems, the object of the present invention is to provide a bank rolling door which has a simple structure, is energy-saving and environmentally friendly, and can convert potential energy into electrical energy.

[0005] In view of the above problems, the following technical solutions are provided: a bank rolling door, comprising a roller, a curtain plate mounted on the roller, support columns fixed at both ends of the roller, a lintel connecting the support columns at both ends, and a motor for driving the roller to rotate, and also comprising a power supply mechanism for supplying power to the motor, the power supply mechanism comprising a battery electrically connected to the motor and a generator, the generator comprising a shell embedded in the support column facing the side wall of the curtain plate, a striking element arranged in the shell, a piezoelectric element arranged on one side of the striking element, and a linkage mechanism for pushing the striking element to hit the piezoelectric element, one end of the linkage mechanism is connected to the striking element, and the other end protrudes from the top wall of the shell, a first spring is arranged between the striking element and the piezoelectric element, a pressure plate for pushing the linkage mechanism is arranged above the generator, a second spring is arranged between the pressure plate and the shell, and a driving mechanism for driving the pressure plate to reciprocate toward the linkage mechanism is arranged on the side wall of the curtain plate.

[0006] In the above structure, when the rolling door is closed or opened, the curtain plate descends or rises to drive the driving mechanism to descend or rise, and the driving mechanism contacts the pressure plate. The driving mechanism pushes the pressure plate to generate pressure, so that the pressure plate applies pressure to the linkage mechanism, pushing the striking element to strike the piezoelectric element, thereby generating current to power the battery. By providing the first spring, the linkage mechanism can be easily reset, and the linkage mechanism can drive the striking element to strike the piezoelectric element again, thereby increasing the reliability of the present invention. By providing the second spring, the pressure plate can be easily reset, thereby increasing the reliability of the present invention. By providing the power supply mechanism, the potential energy of the rising or falling curtain plate can be converted into electrical energy, thereby reducing the consumption of electrical energy and being more environmentally friendly.

[0007] The present invention is further configured such that the driving mechanism comprises a connecting column arranged on the side wall of the curtain plate, the end of the connecting column is provided with a cam matched with the pressure plate, and the cam is rotatable relative to the connecting column.

[0008] In the above structure, when the rolling door is closed or opened, the curtain plate descends or rises to drive the cam to rotate, and the cam rotates to contact the pressure plate. When the cam rolls on the pressure plate, it generates pressure on the pressure plate, so that the pressure plate applies pressure to the linkage mechanism, pushing the striking element to strike the piezoelectric element, thereby generating current to power the battery. By setting the cam, the potential energy of the curtain plate rising or falling can be converted into electrical energy, thereby saving the use of electrical energy and increasing the reliability of the present invention.

[0009] The present invention is further configured such that the driving mechanism is arranged at the front section of the curtain plate.

[0010] By adopting the above structure, the driving mechanism can roll the maximum number of circles on the pressure plate, increasing the number of times the striking element strikes the piezoelectric element, thereby improving the efficiency of power supply and increasing the reliability of the present invention.

[0011] The present invention is further configured such that a plurality of the driving mechanisms are provided and are sequentially spaced apart toward the top of the curtain plate.

[0012] By adopting the above structure, the number of times the striking element strikes the piezoelectric element can be increased, the efficiency of power supply can be improved, and the stability of the pressing plate pressing down can be increased, thereby increasing the reliability of the present invention.

[0013] The present invention is further configured such that a step groove is provided on the side wall of the support column, and the power generation device is arranged in the step groove.

[0014] In the above structure, the compactness of the structure of the present invention can be increased by arranging the stepped groove, thereby improving the structural strength of the vehicle and increasing the reliability of the present invention.

[0015] The present invention is further configured such that a plurality of power generation devices are provided.

[0016] The above structure can enhance the coordination between the driving mechanism and the power generation device, improve the efficiency of power generation, thereby further saving electric energy and increasing the reliability of the present invention.

[0017] The present invention is further configured such that a backup power supply is provided on the top of the support column, and a solar panel electrically connected to the backup power supply is provided on the front end of the door lintel.

[0018] The present invention is further configured such that the solar panels are provided in at least two groups and are evenly distributed at the front end of the door lintel.

[0019] In the above structure, the backup power supply can be stored by setting the solar panel. When the power in the battery is not sufficient, the motor is connected to the backup power supply, so that the curtain plate can be prevented from being unable to rise or fall, thereby increasing the reliability of the present invention. By setting the solar panel, the present invention can be made more environmentally friendly and can further save electric energy, thereby increasing the reliability of the present invention.

[0020] The present invention is further configured such that a lighting lamp is provided on the door lintel, and a sensor head is provided above the lighting lamp.

[0021] With the above structure, the sensor head and the lighting are powered by a battery. The sensor head senses the external light source, and the lighting is turned on at night, thereby increasing the clarity of the camera shooting at the bank entrance and providing light for passers-by walking on the road. In the morning, the sensor head senses and controls the lighting to turn off, thereby saving electricity and increasing the reliability of the utility model.

[0022] Beneficial effects of the present invention: Compared with the existing bank rolling shutter door, the present invention has a simple structure, is energy-saving and environmentally friendly, and can convert potential energy into electrical energy. By setting a power supply mechanism, the potential energy of the curtain plate rising or falling can be converted into electrical energy, thereby reducing the consumption of electrical energy and being more environmentally friendly.
