Description

Technical Field

[0001] This application relates to a window driving component. Background Technology

[0002] For motorized windows, a rack and pinion mechanism is installed. A motor drives a gear, which meshes with the rack and pinion to move the window relative to the frame where the gear is mounted. However, the meshing of the gears requires precision and they can be jammed by debris (such as dust or debris), causing the motorized window to malfunction.

[0003] Therefore, a window-driving component is needed that is simple in structure and runs smoothly. Utility Model Content

[0004] This application aims to solve the above-mentioned problems and therefore provides a window driving assembly, which includes a chain, a rope, a driving assembly, and a window. The rope and the chain are connected to form a loop. The driving assembly is capable of driving the loop to rotate. The window is connected to the loop, so that the rotation of the loop causes the window to move.

[0005] Furthermore, the window drive assembly also includes a connector and a converter. The chain is connected to the rope via the connector to form the loop. The window is connected to the connector via the converter.

[0006] Furthermore, one end of the connector is rotatably connected to the chain, and the other end of the connector is connected to the rope, the connector extending along a first direction. The conversion member extends along a second direction perpendicular to the first direction.

[0007] Furthermore, the window driving assembly also includes a first fixing member and a second fixing member. The connecting member is connected to the conversion member via the first fixing member. The conversion member is connected to the window via the second fixing member.

[0008] Furthermore, the conversion member includes a first arm and a second arm, which are disposed on opposite sides of the connector and clamp the connector. A first fixing member extends along a third direction perpendicular to the first and second directions, passing through the first arm, the second arm, and the connector, thereby connecting the conversion member and the connector. The conversion member abuts against one side of the window, and the second fixing member extends along the first direction and passes through the conversion member, thereby connecting the conversion member and the window.

[0009] Furthermore, one end of the rope is provided with a rope hole. The first fixing member can pass through the conversion member, the connecting member, and the rope hole, thereby connecting the conversion member, the connecting member, and the rope.

[0010] Furthermore, the ratio of the length of the chain to the length of the ring is less than 0.5.

[0011] Furthermore, the drive assembly includes a motor, a housing, a sprocket, a first cover, and a second cover. The motor is capable of driving the sprocket to rotate, and the sprocket can cooperate with the chain to drive the chain to rotate. The housing, the first cover, and the second cover enclose a space, and the sprocket is disposed in the space.

[0012] Furthermore, the drive assembly also includes a first bearing, a second bearing, a first enclosure, and a second enclosure. The first enclosure and the first cover enclose the first bearing, and the second enclosure and the second cover enclose the second bearing. The sprocket is disposed between the first enclosure and the second enclosure.

[0013] Furthermore, the motor has an output shaft. The first cover, the first bearing, and the first enclosure are each provided with a hole through which the output shaft can pass and connect to the sprocket. The output shaft, the sprocket, the first bearing, and the first enclosure rotate together.

[0014] The window driving component of this application has at least the following advantages:

[0015] First, the window drive assembly of this application has a simple structure and is less prone to jamming due to dust or other debris accumulating at the bottom of the window frame. Specifically, the window drive assembly of this application includes a ring-shaped component composed of a chain and a rope. The drive assembly drives the chain, thereby moving the window. This avoids the need for a rack on the window frame, thus preventing dust from accumulating on the rack and causing the window to jam.

[0016] Second, the window driving assembly of this application exhibits excellent driving stability. Specifically, the window driving assembly of this application includes a ring-shaped component composed of a chain and a rope. The chain and rope remain taut at all times compared to a full chain, without any slack or taut sides, thus enabling the driving assembly to stably drive the movement of the window.

[0017] Third, the window driving assembly of this application has excellent connection stability. Specifically, the window driving assembly of this application includes a connector and a converter, thereby stably connecting the ring-shaped member and the window. The connector not only stably connects the chain and rope to form the ring-shaped member, but also cooperates with the converter to convert the overall rotation of the ring-shaped member into the movement of the window.

[0018] Fourth, the window drive assembly of this application has a long service life. Specifically, the window drive assembly of this application includes a housing, a sprocket, a first bearing, a second bearing, a first enclosure, a second enclosure, a first cover, and a second cover. The moving parts, such as the sprocket, the first bearing, and the second bearing, are all housed within the space enclosed by the housing, the first cover, and the second cover, thereby ensuring basic cleanliness. Furthermore, the first bearing is enclosed by the first enclosure and the first cover, and the second bearing is enclosed by the second enclosure.

Detailed Implementation

[0027] The following specific examples illustrate the implementation of this application. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be noted that, unless otherwise specified, the following embodiments and features in the embodiments can be combined with each other.

[0028] It should be understood that although terms indicating direction, such as "up," "down," "left," "right," etc., are used in this application to describe various exemplary structural parts and elements, their use herein is merely for illustrative purposes and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this application can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be considered as limiting.

[0029] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the illustrations only show the components related to this application and are not drawn according to the number, shape and size of the components in actual implementation. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0030] Some exemplary embodiments of this application have been described for illustrative purposes. It should be understood that this application may be implemented in other ways not specifically shown in the accompanying drawings.

[0031] like Figure 1-2 As shown, the window driving assembly of this application includes a driving assembly 10, a chain 20, a rope 30, a positioning member 40, a window 50, and a window frame 60. The window frame 60 is generally rectangular. The window 50 is movable relative to the window, thereby opening or closing the window. The chain 20 and the rope 30 are connected and form a loop. The window 50 is connected to the loop. The driving assembly 10 is capable of driving the loop to rotate around a predetermined trajectory. The driving assembly 10 is disposed on one side of the window frame 60, and the positioning member 40 is disposed on the other side of the window frame 60, thereby substantially positioning the two ends of the predetermined trajectory of rotation of the loop. Specifically, the positioning member 40 includes a wheel. The wheel is fixed to the window frame 60. The rope 30 can pass around the wheel, thereby causing the loop to rotate around the predetermined trajectory. The driving assembly 10 includes a sprocket 11. The sprocket 11 is fixed to the window frame 60. The chain 20 can pass around the sprocket 11, thereby causing the loop to rotate around the predetermined trajectory.

[0032] like Figure 3 As shown, the window drive assembly of this application also includes two connectors 70. The two ends of the rope 30 are connected to the chain 20 via the connectors 70, thereby forming a loop. The chain 20 and rope 30 can be made of materials such as stainless steel or metal, thus possessing good corrosion resistance and water resistance. The chain 20 is formed by several inner and outer links spaced apart. The connector 70 is generally cuboid and extends along a first direction (e.g., ...). Figure 3The chain 20 extends in the front-back direction. The chain 20 is rotatably connected to the proximal end of the connector 70. For example, the end of the connector 70 has a hole. The inner link of the end of the chain 20 matches this hole, and a rotating connector (e.g., a pin) can be inserted into the hole at the end of the connector 70 and the hole in the inner link at the end of the chain 20, thereby rotatably connecting the chain 20 and the proximal end of the connector 70. The connector 70 has a first rope through-hole. The first rope through-hole extends along a second direction perpendicular to the first direction (e.g., in the front-back direction). Figure 3 The connector 70 extends through the connector 70 in a left-right direction. A second rope through-hole 71 is provided at the distal end of the connector 70. The second rope through-hole 71 extends along a first direction and communicates with the first rope through-hole. The second rope through-hole 71 is used to receive the rope 30. During installation, the installer allows the free end of the rope 30 to pass through the second rope through-hole 71 and into the first rope through-hole. The rope 30 is then pulled out, and the end of the rope 30 is knotted or fitted with an expansion joint, etc., so that the size of the end of the rope 30 is larger than the size of the first rope through-hole. Thus, the end of the rope 30 is connected to the connector 70.

[0033] like Figure 3 As shown, the window driving assembly of this application further includes a conversion member 80, a first fixing member 51, and a second fixing member 52. The window 50 is connected to the connector 70 via the conversion member 80. The conversion member 80 is generally cuboid and extends along a second direction. The conversion member 80 includes a first arm 81 and a second arm 82, thereby clamping the connector 70 from opposite sides. The first arm 81 and the second arm 82 are provided with arm through holes. The connector 70 is provided with a matching fixing through hole. The fixing through hole is along a third direction perpendicular to the first and second directions (e.g., ...). Figure 3 The first fastener 51 extends along a third direction and can pass through the arm through hole on the first arm 81, the arm through hole on the second arm 82, and the fastener 70, thereby connecting the connector 70 and the adapter 80. As an example, the first fastener 51 includes a bolt and a nut. One side of the adapter 80 can abut against one side of the window 50, thereby ensuring good connection stability. The adapter 80 is provided with an adapter hole that passes through the adapter 80 along a first direction. The second fastener 52, extending along the first direction, connects the window 50 and the adapter 80. As an example, the second fastener 52 is a screw. The window 50 is provided with a corresponding countersunk hole, and the countersunk hole has a matching thread.

[0034] In one example, the free end of rope 30 passes through the second rope through-hole 71 and enters the first rope through-hole before connecting to a ring (not shown), thus forming a rope hole on the free end of rope 30. The first fastener 51 can pass through the arm through-hole on the first arm 81, the arm through-hole on the second arm 82, the fixing through-hole on the connector 70, and the rope hole of rope 30, thereby connecting the connector 70, the adapter 80, and the rope 30.

[0035] like Figure 1 As shown, the length of chain 20 is less than 0.5 of the length of the ring. That is, chain 20 occupies a small part of the entire ring, and it is only necessary to enable the drive assembly 10 to cooperate with chain 20 so that window 50 can move from one end of window frame 60 to the other (e.g., to open and close).

[0036] like Figure 4-5 As shown, the drive assembly 10 includes a motor 101, a housing 102, a sprocket 11, a first cover, a second cover 14, a first bearing, a second bearing 13, a first enclosure, and a second enclosure 12. The housing 102 is generally annular with both sides connected. The first enclosure and the second enclosure 12 are disposed at both ends of the housing 102 and enclose the housing 102 to form a space. The sprocket 11, the first bearing, the second bearing 13, the first enclosure, and the second enclosure 12 are all disposed in the space. The sprocket 11 can cooperate with the chain 20 to drive the chain 20 to rotate. The first enclosure and the second enclosure 12 are disposed on opposite sides of the sprocket 11. The first enclosure and the first cover enclose the first bearing, and the second enclosure 12 and the second cover 14 enclose the second bearing 13, thereby preventing the first bearing and the second bearing 13 from rusting. Specifically, the first enclosure and the second enclosure 12 are respectively provided with receiving spaces, so that the first bearing and the second bearing 13 can be respectively accommodated in the first enclosure and the second enclosure 12. The first package and the second package 12 can respectively seal the containment space in the first package and the second package 12.

[0037] like Figure 4-5 As shown, the motor 101 has an output shaft 103. The output shaft 103 is rotatable about its axis. A first cover, a first bearing, and a first enclosure are disposed on one side of the sprocket 11 and close to the output shaft 103. The first cover, the first bearing, and the first enclosure are each provided with a hole, allowing the output shaft 103 to pass through the hole and connect to the sprocket 11. When the output shaft 103 rotates, the sprocket 11, the first bearing, and the first enclosure rotate together.

[0038] The window driving component of this application has at least the following advantages:

[0039] First, the window drive assembly of this application has a simple structure and is less prone to jamming due to dust or other debris accumulating at the bottom of the window frame. Specifically, the window drive assembly of this application includes a ring-shaped component composed of a chain and a rope. The drive assembly drives the chain, thereby moving the window. This avoids the need for a rack on the window frame, thus preventing dust from accumulating on the rack and causing the window to jam.

[0040] Second, the window driving assembly of this application exhibits excellent driving stability. Specifically, the window driving assembly of this application includes a ring-shaped component composed of a chain and a rope. The chain and rope remain taut at all times compared to a full chain, without any slack or taut sides, thus enabling the driving assembly to stably drive the movement of the window.

[0041] Third, the window driving assembly of this application has excellent connection stability. Specifically, the window driving assembly of this application includes a connector and a converter, thereby stably connecting the ring-shaped member and the window. The connector not only stably connects the chain and rope to form the ring-shaped member, but also cooperates with the converter to convert the overall rotation of the ring-shaped member into the movement of the window.

[0042] Fourth, the window drive assembly of this application has a long service life. Specifically, the window drive assembly of this application includes a housing, a sprocket, a first bearing, a second bearing, a first enclosure, a second enclosure, a first cover, and a second cover. The moving parts, such as the sprocket, the first bearing, and the second bearing, are all housed within the space enclosed by the housing, the first cover, and the second cover, thus ensuring basic cleanliness. Furthermore, the first bearing is enclosed by the first enclosure and the first cover, and the second bearing is enclosed by the second enclosure and the second cover, further isolating the first bearing and the second bearing, thereby further preventing them from rusting.

[0043] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model.
