Description

Technical Field

[0001] The utility model belongs to the technical field of rolling curtain motors, and in particular relates to a linkage device suitable for an electric rolling curtain motor and an electric rolling curtain. Background Art

[0002] The electric roller shutter is installed indoors or between double-glazed windows to avoid adverse external influences and increase the service life of the system. It can block sunlight and reduce air-conditioning load in summer and adjust visual comfort in winter to meet users' high-quality requirements. When the motor of the electric roller shutter is running, the rubber plug at the output end of the motor drives the curtain fabric to move up and down. At the same time, the tail plug on the linkage bearing rotates synchronously with the rubber plug at the output end of the motor to drive the curtain fabric to move up and down more stably.

[0003] The prior art discloses a linkage device suitable for an electric roller blind motor with a patent announcement number of CN 219101183 U. The first rubber plug and the second rubber plug of the above patent are both embedded in the curtain roller shaft. The motor drives the first rubber plug to rotate and transmits the force in the rotation direction to the second rubber plug. The second rubber plug rotates synchronously through the linkage mechanism, thereby achieving that while ensuring that there is a large friction between the second rubber plug and the inner side of the curtain roller shaft, the friction between the second rubber plug and the inner shell of the motor is reduced, effectively solving the problem that the rubber plug at the driven end of the electric roller blind is subject to large resistance when rotating relative to the inner shell of the motor. However, the following deficiencies still exist in actual use: from a practical point of view, the roller blind motor will vibrate when in use, and the vibrating motor will collide with the sleeve, which will generate noise and affect the use of the electric roller blind. Moreover, when the device is in use, the socket will still have a large friction with the sleeve, affecting the rotation of the second rubber plug, thereby causing a large obstacle to the rolling of the electric roller blind.

[0004] Therefore, a linkage device suitable for an electric roller shutter motor and an electric roller shutter are needed to solve the problems in the prior art that the vibrating motor will collide with the sleeve, generating noise affecting the use of the electric roller shutter, and the sleeve will still have a large friction with the sleeve, affecting the rotation of the second rubber plug.

DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the embodiments.

[0025] See also Figure 1-5 The utility model provides a linkage device suitable for an electric roller shutter motor, comprising a tubular motor 1, a shock absorbing mechanism 2, a sleeve 3, a first rubber plug 4, a sleeve mechanism 5 and a second rubber plug 6. The shock absorbing mechanism 2 is sleeved on the outside of the tubular motor 1, the sleeve 3 is sleeved on the outside of the shock absorbing mechanism 2, the first rubber plug 4 is arranged at the output end of the tubular motor 1, the sleeve mechanism 5 is arranged on the right side inside the sleeve 3, and the second rubber plug 6 is arranged on the outside of the sleeve mechanism 5.

[0026] The shock absorbing mechanism 2 is composed of a first buffer layer 201, an inner connecting ring 202, a connecting block 203, a spring 204, a damper 205, an outer connecting ring 206 and a second buffer layer 207. The first buffer layer 201 is sleeved on the outside of the tubular motor 1, the inner connecting ring 202 is sleeved on the outside of the first buffer layer 201, the outer connecting ring 206 is arranged on the outside of the inner connecting ring 202 through a shock absorbing assembly, and the second buffer layer 207 is sleeved on the outside of the outer connecting ring 206.

[0027] Further Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the shock absorbing assembly consists of a connecting block 203, a spring 204 and a damper 205. The connecting block 203 is symmetrically fixedly connected to the two ends of the spring 204, the damper 205 is sleeved inside the spring 204, and the two ends of the damper 205 are respectively fixedly connected to the connecting block 203, and the shock absorbing assembly is respectively fixedly connected to the outer surface of the inner connecting ring 202 and the inner surface of the outer connecting ring 206 through the connecting block 203.

[0028] Further Figure 2 , Figure 3 and Figure 4 As shown, it is worth explaining in detail that the shock absorbing components are evenly and symmetrically arranged along the center of the tubular motor 1 and are evenly installed between the inner connecting ring 202 and the outer connecting ring 206 .

[0029] Further Figure 2 , Figure 3 and Figure 4 As shown, it is worth to explain in detail that the materials of the first buffer layer 201 and the second buffer layer 207 are both set as rubber layers;

[0030] The rubber buffer layer has high elasticity and can absorb and disperse impact energy, effectively reducing the impact force on the equipment; at the same time, it also increases the friction between the tubular motor 1 and the sleeve 3, ensuring the stability of the shock absorbing mechanism 2 sleeved between the tubular motor 1 and the sleeve 3.

[0031] According to the above working process, it can be known that: through the provided shock absorbing mechanism 2, when the tubular motor 1 is in use, the tubular motor 1 generates vibration, which is buffered by the shock absorbing mechanism 2, so that the vibration transmitted from the tubular motor 1 to the sleeve 3 is weakened, and the noise between the sleeve 3 is also reduced after the weakening, so that the tubular motor 1 achieves the effect of noise reduction and vibration reduction.

[0032] Further Figure 2 , Figure 3 and Figure 5As shown, it is worth specifically explaining that the socket mechanism 5 is composed of a socket member 501, a ball 502, a connecting end 503 and an oil inlet pipe 504. The socket member 501 is arranged on the right side of the inner part of the sleeve 3, the ball 502 is evenly rolled and connected to the inner part of the socket member 501, the connecting end 503 is fixedly connected to one end of the socket member 501 extending out of the sleeve 3, the second rubber plug 6 is socketed on the outside of the connecting end 503, and a rolling groove 508 is opened at the position of the ball 502 corresponding to the sleeve 3 for the ball 502 to roll.

[0033] Further as Figure 2 , Figure 3 and Figure 5 As shown, it is worth to explain in detail that the oil inlet pipe 504 is fixedly connected to the inside of the connecting end 503, and a through groove 505 is opened in the inner center of the sleeve 501, and the through groove 505 is connected to the oil inlet pipe 504;

[0034] Oil is injected into the oil storage tank 507 through the oil inlet pipe 504, thereby improving the practicality of the mechanism.

[0035] Further as Figure 2 , Figure 3 and Figure 5 As shown, it is worth to explain in detail that an annular oil storage groove 507 is opened inside the sleeve 501, and the oil storage groove 507 is connected with the connecting groove 506, and is connected with each ball 502 on the same plane;

[0036] Since the ball 502 can absorb the lubricating oil in the oil storage tank 507 when rolling, the friction between the ball 502 and the sleeve 3 is further reduced.

[0037] An electric rolling curtain comprises a linkage device suitable for the electric rolling curtain motor.

[0038] This solution has the following working process: when in use, the shock absorbing mechanism 2 is sleeved on the outside of the tubular motor 1, and then the sleeve 3 with the sleeve mechanism 5 is sleeved on the outside of the shock absorbing mechanism 2, and the first rubber plug 4 is driven to rotate by the tubular motor 1. When the tubular motor 1 is in use, vibration will be generated, and the vibration is transmitted to the spring 204 and the damper 205 through the first buffer layer 201, the inner connecting ring 202, and the connecting block 203 in sequence, and is buffered by the spring 204 and the damper 205, and then transmitted to the sleeve 3 through the outer connecting ring 206 and the second buffer layer 207. Due to the material characteristics of the first buffer layer 201 and the second buffer layer 207, part of the impact force can be weakened, and then through the buffering effect of the spring 204 and the damper 205, the impact force can be reduced. The impact force is weakened in one step, thereby weakening the noise between the tubular motor 1 and the sleeve 3, so that the tubular motor 1 can achieve the effect of noise reduction and vibration reduction; at this time, the first rubber plug 4 rotates, and the second rubber plug 6 on the other side can be driven to rotate through the reel sleeved on the outside of the first rubber plug 4 and the second rubber plug 6, and the sleeve 501 is driven to rotate at the same time, and the ball 502 is connected to the inside of the rolling groove 508 by rolling, so as to reduce the friction between the sleeve 501 and the inner wall of the sleeve 3. At the same time, when the ball 502 rolls, the lubricating oil in the oil storage tank 507 further reduces the friction between the sleeve 3, improves the smoothness of the rotation of the sleeve 501, reduces the rotation resistance of the second rubber plug 6, and then improves the smoothness of the rotation of the first rubber plug 4, so as to ensure the smooth winding of the electric roller blind.

[0039] In summary: through the provided shock absorbing mechanism 2, when the tubular motor 1 is in use, the tubular motor 1 generates vibration, which is buffered by the shock absorbing mechanism 2, so that the vibration transmitted from the tubular motor 1 to the sleeve 3 is weakened, and the noise between the sleeve 3 is also reduced after the weakening, so that the tubular motor 1 achieves the effect of noise reduction and vibration reduction; through the provided socket mechanism 5, the socket 501 is rotatably connected to the inside of the sleeve 3 through the ball 502, thereby reducing the friction with the sleeve 3, and at the same time, by adding lubricating oil, the friction can be further reduced, thereby improving the smoothness of the rotation of the socket 501 and the smoothness of the rotation of the first rubber plug 4, thereby ensuring the smooth use of the electric roller blind.
