It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Nowadays, the application of the roller shutter facilities is increasingly popular in daily life of people, for example, the roller shutter is used as a door curtain structure of a shop to realize an antitheft function, or the roller shutter is used as a sunshade curtain to realize the sun-shading and sun-screening purposes of outdoor travel of people, and other application scenes, but the conventional roller shutter structure can be only unfolded or contracted entirely, so that hovering of the roller shutter structure under specific length and size cannot be realized according to actual demands of users.

Based on the above technical problems, the embodiments of the present application provide a roller shutter assembly 100 applied to a motor apparatus, please refer to fig. 1, 2 and 4, fig. 1 is a schematic overall structure diagram of the roller shutter assembly 100 provided in the embodiments of the present application, fig. 2 is a schematic explosion structure diagram of the roller shutter assembly 100 shown in fig. 1, and fig. 4 is a schematic assembly structure diagram of a rotation locking structure 120, a first mounting seat 130 and a protection cover 180 in the roller shutter assembly 100 provided in the embodiments of the present application.

As shown in fig. 1, 2 and 4, the roller shutter assembly 100 provided in this embodiment includes a shutter body 110, at least one rotation locking structure 120, a first mounting seat 130 and an elastic structure 140, wherein the elastic structure 140 is connected to the shutter body 110, and the shutter body 110 can be unfolded in a direction away from the automotive device or contracted in a direction close to the automotive device, so as to achieve the purpose of sun-shading and sun-screening for outdoor travel of the automotive device or reduce the external volume of the automotive device.

Meanwhile, referring to fig. 5 and fig. 6, fig. 5 is a schematic view illustrating another angle of the first mounting seat 130 in the roller shutter assembly 100 shown in fig. 4, and fig. 6 is a schematic view illustrating another angle of the rotation locking structure 120 in the roller shutter assembly 100 shown in fig. 4.

As shown in fig. 2 and fig. 4 to fig. 6, in the above embodiment, at least one rotation locking structure 120 is disposed on one side of the curtain body 110 or on two sides of the curtain body 110, and each rotation locking structure 120 includes a limiting member 121. The first mounting seat 130 is disposed on a side of the rotation locking structure 120 away from the curtain body 110, and the first mounting seat 130 includes a first sliding rail 131 and a second sliding rail 132 that are mutually communicated, and at the same time, an end of the second sliding rail 132 away from the first sliding rail 131 is provided with a stop portion 1321.

When a user needs to expand the curtain body 110 to achieve the purpose of sunshade and sun-screening for outdoor travel of the mobile device, a tensile force can be applied to the curtain body 110, and the curtain body 110 can be expanded along a direction away from the mobile device, at this time, the elastic structure 140 is connected to the curtain body 110, so that the curtain body 110 can drive the elastic structure 140 to twist and deform during the moving process; meanwhile, in the moving process of the curtain body 110, since the at least one rotation locking structure 120 is disposed on one side of the curtain body 110 or disposed on two sides of the curtain body 110 respectively, the curtain body 110 can also drive the rotation locking structure 120 and the limiting member 121 to rotate, and the limiting member 121 can be displaced in the first sliding rail 131, so that the purpose of smooth unfolding of the curtain body 110 is achieved.

When the user adjusts the unfolding dimension of the curtain body 110, the user can stop applying the pulling force to the curtain body 110, because the curtain body 110 has driven the elastic structure 140 to twist and deform the elastic structure 140 in the previous moving process, and the curtain body 110 is in a static state at this time, the deformed elastic structure 140 can generate a reaction force (i.e. resume deformation) opposite to the moving direction of the curtain body 110, and drive the curtain body 110 and the rotation locking structure 120 to reversely displace, and the limiting piece 121 can correspondingly reversely displace, i.e. the limiting piece 121 can slide from the first sliding rail 131 to the second sliding rail 132 and finally abut against the abutting part 1321, thereby realizing the locking function of the rotation locking structure 120, further realizing the hovering of the rolling curtain structure under specific length and dimension according to the actual requirement of the user.

It can be understood that, in the present embodiment, by rotating the rotation locking structure 120 to make the limiting member 121 move in the first sliding rail 131 and the second sliding rail 132, the accuracy of the displacement stroke of the limiting member 121 can be further ensured; meanwhile, the specific structure of the elastic structure 140 is not limited in this embodiment, and for example, the elastic structure 140 may be a rubber member, a device made of elastic fiber material, or a spring, so long as the purpose of generating a reaction force opposite to the moving direction of the curtain 110 and driving the curtain 110 and the rotation locking structure 120 to rotate reversely when recovering the deformation can be achieved. It should be noted that, in the above embodiment, the elastic structure 140 is preferably a spring.

Alternatively, as shown in fig. 1 and 2, in one embodiment, the number of rotational locking structures 120 may be only one, and the roller blind assembly 100 may further include a loading tube 150 and a fixing base 160. Wherein, curtain body 110 is fixedly connected to load tube 150 along the length direction of load tube 150, rotation locking structure 120 and fixing base 160 are respectively disposed at two sides of load tube 150, and at the same time, elastic structure 140 may be disposed between load tube 150 and fixing base 160.

It can be appreciated that, when the curtain 110 is deployed in a direction away from the motorized equipment (which may be in a direction away from the loading tube 150), since the rotation locking structure 120 and the elastic structure 140 are both rotated in a direction of displacement of the curtain 110, the fixing base 160 needs to be fixedly connected (i.e. the fixing base 160 cannot be rotated in synchronization with the rotation locking structure 120 and the elastic structure 140), so that one end of the elastic structure 140 connected to the fixing base 160 is fixed, and one end of the elastic structure away from the fixing base 160 is continuously rotated, so that the curtain 110 can drive the elastic structure 140 to twist and deform during moving.

In addition, referring to fig. 2 in combination with fig. 3, fig. 3 is an enlarged schematic view of a portion a of the roller shutter assembly 100 shown in fig. 2.

As shown in fig. 2 and 3, in the above embodiment, the loading tube 150 may be a hollow structure, and the curtain body 110 may be wrapped around the loading tube 150 in a contracted state, the rotation locking structure 120 may include a third mounting seat 123, the third mounting seat 123 is disposed on a side of the first mounting seat 130 near the loading tube 150, and meanwhile, the roller shutter assembly 100 may further include a fourth mounting seat 170, the fourth mounting seat 170 is disposed on an end of the elastic structure 140 far away from the fixed seat 160, where the third mounting seat 123 and the fourth mounting seat 170 are respectively inserted into two ends of the loading tube 150, so that the rotation locking structure 120, the loading tube 150 and the fourth mounting seat 170 are fixedly connected, and the fourth mounting seat 170 is rotatably connected to the fixed seat 160. It can be appreciated that, when the curtain 110 is deployed in a direction away from the motorized equipment, the curtain 110 can drive the rotation locking structure 120, the loading tube 150 and the fourth mounting seat 170 to rotate synchronously, and the elastic structure 140 is fixedly connected to one end of the fixing seat 160, so that the purpose of driving the elastic structure 140 to twist and deform during the movement of the curtain 110 can be achieved.

It should be noted that, in the present embodiment, the outer surface of the third mounting seat 123, the outer surface of the fourth mounting seat 170 and the inner wall of the loading tube 150 may be configured as a polygonal structure as shown in fig. 3, so as to improve the driving efficiency of the rotation locking structure 120 and the elastic structure 140 near one end of the fourth mounting seat 170 when the loading tube 150 rotates.

In addition, it is understood that in other embodiments of the present application, a plurality of rotation locking structures 120 may be disposed, and the plurality of rotation locking structures 120 are disposed at two ends of the curtain body 110, and two ends of the elastic structure 140 are connected to the rotation locking structures 120 at two ends of the curtain body 110. In this embodiment, the rotation ranges of the rotation locking structures 120 at two ends of the curtain body 110 (i.e. the rotation range of the rotation locking structure 120 at one end of the curtain body 110 is larger and the rotation range of the rotation locking structure 120 at the other end of the curtain body 110 is smaller) may be respectively set, so as to achieve the purpose that the curtain body 110 drives the elastic structure 140 to twist and deform during the movement process.

Alternatively, referring to fig. 5 and 6, in an embodiment, the rotation locking structure 120 may further include a second mounting seat 122, where the second mounting seat 122 is covered on the first mounting seat 130, and a moving groove 1221 for the limiting member 121 to reciprocate is formed along the axial direction, where when the curtain 110 drives the rotation locking structure 120 to rotate, the limiting member 121 reciprocates in the moving groove 1221 and moves in the first sliding rail 131.

It can be understood that when the curtain 110 drives the rotation locking structure 120 to rotate during the moving process (at this time, the first mounting seat 130 is fixed), the rotation locking structure 120 can rotate clockwise, and then the limiting member 121 can also rotate clockwise in the first sliding rail 131 and the second sliding rail 132, so as to achieve the purpose of smooth unfolding of the curtain 110.

When the pulling force is stopped to the curtain 110, the deformed elastic structure 140 generates a reaction force (i.e. returns to deform) opposite to the moving direction of the curtain 110, and drives the curtain 110 and the rotation locking structure 120 to rotate reversely, i.e. the limiting member 121 rotates in the first sliding rail 131 and the second sliding rail 132 in the counterclockwise direction at this time, and finally abuts against the abutting portion 1321, thereby realizing the locking function of the rotation locking structure 120, and further realizing the hovering of the rolling curtain structure under a specific length and size according to the actual requirement of a user.

In addition, referring to fig. 6, in the above embodiment, a recessed area 1222 is further provided on the side of the second mounting seat 122 facing the first mounting seat 130, and the first sliding rail 131 and the second sliding rail 132 may be located in the recessed area 1222, so that the limiting element 121 can be limited secondarily by using the recessed area 1222, and the reliability of hovering of the roller shutter assembly 100 is ensured.

It will be appreciated that the specific shape of the limiting member 121 is not limited in this embodiment, and may be, for example, a sphere, a polygonal body, or a square structure, preferably a sphere, so that the friction force during the displacement of the limiting member 121 can be further reduced.

Optionally, as shown in fig. 5, in an embodiment, the first mounting seat 130 may further include a third sliding rail 133, where the third sliding rail 133 is disposed near a center of the first mounting seat 130, and the third sliding rail 133 is respectively communicated with the first sliding rail 131 and the second sliding rail 132, so as to further improve the diversity of displacement travel of the limiting member 121.

In addition, referring to fig. 5, in a preferred embodiment of the present application, the first sliding rail 131 and the third sliding rail 133 may have a spiral coil structure, and the first sliding rail 131 includes a first travel portion 1311, a first end portion 1312 and a second end portion 1313 at two ends, and the third sliding rail 133 includes a second travel portion 1331, a third end portion 1332 and a fourth end portion 1333 at two ends, wherein the first end portion 1312 of the first sliding rail 131 is communicated with the second sliding rail 132, and the second end portion 1313 of the first sliding rail 131 is communicated with the first travel portion 1311 of the first sliding rail 131; the third end 1332 of the third rail 133 communicates with the second stroke 1331 of the third rail 133, the second stroke 1331 of the third rail 133 communicates with the second rail 132, and the fourth end 1333 of the third rail 133 communicates with the first stroke 1311 of the first rail 131.

Specifically, as shown in fig. 5, when the curtain 110 drives the rotation locking structure 120 to rotate during the moving process, the rotation locking structure 120 may rotate clockwise, and then the limiting member 121 may also rotate clockwise in the first sliding rail 131 and the second sliding rail 132, and at this time, the limiting member 121 may take the first end 1312 of the first sliding rail 131 as a starting point, displace along the track direction (i.e. the first travel portion 1311) of the first sliding rail 131, and finally reach the second end 1313 of the first sliding rail 131, and if the curtain 110 is not fully unfolded, the limiting member 121 may continue to perform the cyclic displacement along the track direction (i.e. the first travel portion 1311) of the first sliding rail 131 until the curtain 110 is fully opened.

When the pulling force is stopped, the deformed elastic structure 140 generates a reaction force (i.e. returns to the deformed state) opposite to the moving direction of the curtain body 110, and drives the curtain body 110 and the rotation locking structure 120 to reversely displace, and the limiting member 121 correspondingly displaces reversely, i.e. the limiting member 121 can slide from the first sliding rail 131 to the second sliding rail 132 and finally abut against the abutting portion 1321, thereby realizing the locking function of the rotation locking structure 120.

When a pulling force is applied to the curtain 110 again, the limiting member 121 slides from the second sliding rail 132 to the first sliding rail 131, and since the second travel portion 1331 of the third sliding rail 133 is communicated with the second sliding rail 132, the limiting member 121 enters the second travel portion 1331 of the third sliding rail 133 during the sliding from the second sliding rail 132 to the first sliding rail 131 and is located at the lowest point in the second travel portion 1331 under the action of gravity, and meanwhile, under the action of the pulling force, the limiting member 121 continuously performs a circular displacement along the track direction of the third sliding rail 133 (i.e., the direction from the third end portion 1332 of the third sliding rail 133 to the fourth end portion 1333 of the third sliding rail 133); in this case, when the curtain 110 is to be contracted, the application of the pulling force to the curtain 110 may be stopped, and the fourth end 1333 of the third rail 133 and the first stroke 1311 of the first rail 131 communicate with each other, so that the sum of the stroke distances of the second stroke 1331 of the third rail 133 and the first stroke 1311 of the first rail 131 can completely contract the curtain 110.

Optionally, as shown in fig. 5, in an embodiment, the communicating portion between the first sliding rail 131 and the second sliding rail 132 and the communicating portion between the first sliding rail 131 and the third sliding rail 133 may be provided with a limiting portion 134, where the plurality of limiting portions 134 are respectively arranged in an inclined manner along a direction away from the second sliding rail 132 and the third sliding rail 133, so that, after the limiting member 121 enters the sliding rail, the limiting portion 134 arranged in an inclined manner may have a limiting effect on the limiting member 121, and thus the mechanical structure reliability of hovering of the roller shutter assembly 100 is improved.

Optionally, as shown in fig. 4, in other embodiments of the present application, the roller shutter assembly 100 may further include a protection cover 180, where the protection cover 180 covers the rotation locking structure 120 and the first mounting seat 130, so as to achieve a protection effect on the rotation locking structure 120 and the first mounting seat 130; meanwhile, one side of the protection cover 180, which is away from the rotation locking structure 120, can be abutted against the curtain body 110, so that an axial limiting effect on the curtain body 110 is achieved.

The present embodiment further provides a motorized device, including the roller shutter assembly 100 according to any one of the foregoing embodiments, and it is to be understood that the motorized device provided in this embodiment may be a motor vehicle such as a pick-up card or an automobile, or may be a motor ship such as a ship or a yacht, or may be a curtain structure of a shop, that is, may include the roller shutter assembly 100 as long as it is within the scope of protection of the present application.
