Description

Technical Field

[0001] The present application relates to the field of sunshade technology, and in particular to a connecting piece of a driver and a sunshade device. Background Art

[0002] One end of the driver of the sunshade device, especially the windproof roller blind, needs to be fixed on the mounting assembly. The mounting assembly is mainly used to support the torque and bending moment of the windproof roller blind. Usually the mounting assembly is fixed and cannot move. Accordingly, the end of the driver connected to the mounting assembly is also fixed. Because the volume of the fabric in the winding assembly of the sunshade device will increase or decrease when it is wound, the position of the fabric perpendicular to the winding tube will be displaced, causing wear. Utility Model Content

[0003] The present application provides a connecting piece of a driver and a sunshade device, which are used to improve the problems that the driver in the sunshade device cannot move, the bearing capacity of the mounting assembly is insufficient, the reliability of the connection and fastening between the mounting assembly and the rotating element is poor, and the mounting assembly does not have position adjustment, resulting in poor versatility. To achieve the purpose, the embodiments of the present application include the following solutions.

[0004] In a first aspect, the present application provides a connecting piece of a driver, comprising: a first connecting hole, a second connecting hole, a third connecting hole, a fourth connecting hole, a fifth connecting hole, a polygonal hole, a first groove, a second groove, a first flange, and a second flange.

[0005] In one implementation, the connecting member is made of metal and is prepared by casting, sheet metal and / or machining, and the interior of the first flange and the second flange includes a first connecting hole and a second connecting hole.

[0006] In this implementation, the first flange, the second flange and the main body of the connector are integrated, which can increase the depth of the connection hole, increase the material thickness of the connection and fastening, improve the reliability of the connection and fastening, and also have the functions of space adjustment and friction reduction. Preparation by metal die casting also simplifies the production process between the various features.

[0007] In one implementation, the axis of the first connection hole is parallel to and horizontally connected to the axis of the second connection hole. The first connection hole and the second connection hole are used to connect with a rotating part.

[0008] In this implementation, the axis of the first connecting hole remains parallel and horizontal with the axis of the second connecting hole, and the end faces of the first flange and the second flange are at the same height, so that the rotating element connected thereto can work in a straight line position, giving the connecting part a sliding function.

[0009] In one implementation, the polygonal hole is used for positioning and connecting shaft parts, the third connecting hole is used for connecting and fastening shaft parts, the polygonal hole and the third connecting hole are located at the center of the connecting piece, and the third connecting hole is connected to the shaft part through a fastener.

[0010] In this implementation, the polygonal hole and the shaft parts are connected by a profile connection. The polygonal hole is a countersunk hole, which can limit the freedom of rotation of the shaft parts and locate the connection position of the shaft parts, making assembly simpler, and the shaft parts can withstand bending moment and / or torque. Such a design also improves the compatibility of the connector, and can achieve compatibility with different drivers by only switching the connected shaft parts.

[0011] In one implementation, the fourth connecting hole and the fifth connecting hole are stepped waist-shaped holes, waist-shaped holes, round holes or special-shaped holes.

[0012] In this implementation, the waist-shaped hole can adjust the connection and firmness position between the connector and the driver. When the waist-shaped hole is fixed with the driver using a fastener, the size can be fine-tuned to align the position of the fastener with the connection position of the driver to the maximum extent, thereby improving the compatibility of the connector connection. The waist-shaped hole is provided with a step outside to accommodate the boss of the fastener, which reduces the volume between the connector and the mating parts and avoids the generation of friction.

[0013] In an implementation manner, one side of the first groove and the second groove further includes a slope.

[0014] In this implementation, the first groove and the second groove are cable wiring grooves of the driver, which can avoid interference between the cables and the covering of the sunshade device. In the case of a small-volume assembly, the inclined surface can make the outlet position of the driver cable deviate from the groove, which can reduce the elasticity of the cable bending to ensure the smooth direction of the outlet, further saving space inside the sunshade device.

[0015] In a second aspect, the present application provides a sunshade device, comprising a driver, a rotating element and a connector provided by any of the above-mentioned implementation methods, wherein the connector is used for connecting and fastening the driver and the rotating element in the sunshade device.

[0016] The sunshade device provided by the present application uses the connecting piece provided by the first aspect of the present application to connect the driver and the rotating element. Since the connecting piece in the present application has the functions of making the driver slide, being small in size, having strong load-bearing capacity, reliable connection and fastening, and having position adjustment, the internal space of the sunshade device is saved and the reliability of the sunshade device is improved.

[0017] Additional aspects and advantages of the present application will be given in part in the description below, and in part will become apparent from the description below, or will be learned through the practice of the present application. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] See also Figure 1-Figure 11 The present application discloses a connecting member of a driver, comprising a first connecting hole 11, a second connecting hole 12, a third connecting hole 13, a fourth connecting hole 14, a fifth connecting hole 15, a polygonal hole 16, a first groove 21, a second groove 22, a first flange 31, and a second flange 32. The first connecting hole 11 is arranged inside the first flange 31, the second connecting hole 12 is arranged inside the second flange 32, the polygonal hole 16 is arranged at the center of the connecting seat, the first connecting hole 11 and the second connecting hole 12 are used to connect with the rotating element 60, the first groove 21 and the second groove 22 are respectively arranged at the edge of one side of the connecting seat, the first groove 21 and the second groove 22 are used to lay the cable 102 of the driver 10, the third connecting hole 13 is used to connect and fasten with shaft parts, and the fourth connecting hole 14 and the fifth connecting hole 15 are used to connect and fasten the driver 10.

[0041] In one embodiment, the material of the connection seat is metal such as aluminum alloy, zinc alloy, stainless steel, etc., and is prepared by casting and / or machining. Exemplarily, the material of the connection seat is aluminum alloy, which is formed by die casting. In this way, the holes, grooves, chamfers, flanges, etc. of the connection seat can be simply made without drilling holes, chamfering, etc. through machining, which saves production time. With such a design, the main body of the connection seat and the first flange 31 and the second flange 32 are a whole. When the first connection hole 11 and the second connection hole 12 are threaded holes, the first flange 31 and the second flange 32 form a threaded flange, which is easy to install and maintain. The design of the flange also makes the number of threaded turns of the connection more, which also increases the material thickness of the connection and improves the reliability of connection and fastening.

[0042] In some embodiments, see Figure 1-Figure 3, the first connection hole 11 and the second connection hole 12 are holes with connection and fastening functions, such as threaded holes, rivet holes or tapered holes, etc., which can be connected to the rotating element 60 by threaded connection, rivet connection or expansion connection. Exemplarily, the first connection hole 11 and the second connection hole 12 are threaded holes, and the rotating element 60 is a part that can be axially fixed and radially rotatable, such as a bearing, a cam, a universal ball, etc. Exemplarily, the rotating element 60 is a bearing. Exemplarily, the first connection hole 11 and the second connection hole 12 are connected and fastened to the rotating element 60 through a fastener 61. The fastener 61 is a part that can be axially connected and fastened, such as a bolt, a rivet, etc. Exemplarily, the fastener 61 is a bolt.

[0043] Furthermore, the axis of the first connecting hole 11 is parallel to the axis of the second connecting hole 12 and is horizontally connected, and the first end face 311 of the first flange 31 and the second end face 322 of the second flange 32 are equal in height. In this way, the connecting seat has a sliding function after being connected to the fastener 61 and the rotating element 60, which can enable the driver to slide in the X direction.

[0044] In some embodiments, the first flange 31 and the second flange 32 also have the function of space adjustment and friction reduction. They are used to adjust the distance between the rotating element 60, the connecting seat and the guide rail 70 so that no friction is generated between the mating parts assembled therewith. For example, please refer to Figure 4 The figure shows a side view of the outer shape of the assembly structure of the connecting seat and the guide rail 70, wherein the connecting piece can slide in the guide rail 70 after being connected to the rotating element 60. The first flange 31 and the second flange 32 play a role in adjusting the distance between the connecting piece and the guide rail 70 so that the guide rail 70 does not generate friction with the connecting piece.

[0045] In some embodiments, the third connecting hole 13 is arranged at the center of the connecting seat, the third connecting hole 13 is used for the connection and fastening of shaft parts, and the polygonal hole 1 is used for the positioning and position constraint of shaft parts. The third connecting hole 13 is a hole with connection and fastening functions, such as a threaded hole, a pin hole, a tapered hole, a through hole, etc. Exemplarily, the third connecting hole 13 is a chamfered through hole. The number of sides of the polygonal hole 16 is not limited here, and it is mainly to meet the positioning and / or position constraints of the shaft parts. That is, the polygonal hole 16 can constrain the rotation of the shaft parts in the X, Y, and Z directions and / or constrain the displacement of the shaft parts in the Z direction. Exemplarily, the shaft parts are metal products and can withstand torque and / or bending moments.

[0046] For example, see Figure 5, (a1), (b1) and (c1) in the figure respectively show the front and back side views and partial cross-sectional schematic diagrams of the exploded schematic diagram of the assembly structure of the connecting member and the rotating element 60, the fastener 61 and the first fastener 62. The polygonal hole 16 is connected to the shaft part by a surface. Exemplarily, the shaft part is a square shaft 63 with an internal threaded hole. The bottom surface 600 of the square shaft coincides with the bottom surface 601 of the polygonal hole, and the first fastener 62 passes through the third connecting hole 13 to connect and fasten the square shaft 63. After being fastened, the square shaft 63 is limited by the polygonal hole 1, and its rotational freedom around the X, Y and Z directions is completely fixed. The bottom surface 601 of the polygonal hole also limits the displacement of the square shaft 63 in one direction of the Z direction, and it can only be placed in the direction of the opening of the polygonal hole 16. In this embodiment, the shaft part can withstand bending moment and torque. Exemplarily, the first fastener 62 is a countersunk bolt.

[0047] In some embodiments, the shaft part is a round shaft 64 with an internal threaded hole, which can also be connected by the above-mentioned first fastener 62 and the connecting member. Since the round shaft is a cylinder, it can only support bending moment but not torque. Figure 6 , the figure shows an exploded schematic diagram of the circular shaft 64 and the connecting member, the fastener 61, the first fastener 62, and the rotating element 60. In this embodiment, combined with Figure 5 , Figure 6 As shown, the round shaft 64 and the square shaft 63 can be connected and fastened by the first fastener 62. The shaft parts can also be combined into other shapes and connected with the connecting parts. The purpose is to connect and fasten and make the shaft parts have the function of supporting bending moment and / or torque. For the sake of brevity, it will not be repeated.

[0048] In some embodiments, the connector and the shaft parts are integrally prepared by die casting or connected by welding, which can save the use of fasteners and simplify the production process. Figure 7 , an embodiment of the connecting piece is shown in the figure, wherein (a2) and (b2) respectively show the front and back side views of the connecting piece. In this embodiment, the connecting piece and the shaft part are integrally formed and prepared by die casting.

[0049] In some embodiments, the connection seat is provided with one or more fourth connection holes 14 and fifth connection holes 15, which have the functions of position adjustment and connection fastening. They are used to connect with the driver 10. The fourth connection hole 14 is a stepped waist-shaped hole or a waist-shaped hole, and the fifth connection hole 15 is a round hole or a special-shaped hole or a waist-shaped hole. In this embodiment, there is no restriction on the position and number of the fourth connection hole 14 and the fifth connection hole 15, which can be at any position of the connection piece and completely on the surface of the connection piece. Please refer to Figure 7-Figure 9, exemplarily, the number of the fourth connection holes 14 is 4, which are symmetrically arranged with respect to the center of the connection base and the X direction. The number of the fifth connection holes 15 is 8, which are symmetrically arranged with respect to the center of the connection base and the Y direction. Exemplarily, when the position deviation of the eighth connection hole 58 (exemplarily, the eighth connection hole is a bottom hole for a self-tapping screw or an internal threaded hole) of the driver 5 connected to the fourth connection hole 14 is large, the waist-shaped feature can enable the third fastener 53 (exemplarily, the third fastener is a self-tapping screw or a screw) to be connected and fastened to the driver 10 by adjusting the position.

[0050] In some embodiments, the connecting member is made of steel and is prepared by sheet metal processing and machining. Fig.10 , the figure shows the front and back side views of the connector prepared by sheet metal processing and machining. The number of the fourth connection holes 14 in the figure is 4, and the number of the fifth connection holes 15 is 6. In this embodiment, the connector can also be prepared by die casting or machining.

[0051] Further, please see Fig. 9 The step on the fourth connecting hole 14 forms a receiving cavity to accommodate the boss 533 of the fastener 53, so that the fastener 53 will not interfere with the guide rail 56. The guide rail 56 is a part with linear guidance and limit functions and is used for the sliding of the rotating element 60. With such a design, the position between the connecting member and the assembly part in the Z direction can be made smaller. As shown in the figure, the first space 90 formed between the connecting member and the guide rail 56 can be made smaller, saving the internal space of the sunshade device.

[0052] In some embodiments, please see Figure 1-Figure 2 and Figure 8 The connection seat is provided with one or more first grooves 21 and second grooves 22, which are separately provided at the edge of the connection seat and are used for laying out the cables of the driver 10. The first groove 21 and the second groove 22 may exist at the same time, or only one may exist. It has the function of avoiding interference and friction between the cables and the assembly parts of the sunshade device due to the laying out of the cables, and also saves the internal space of the sunshade device. The first groove 21 and the second groove 22 also include an inclined surface 101. By way of example, in combination Fig.11 , Fig.11 1 shows a partial assembly structure of a sunshade device for a windproof roller blind, wherein the cable 102 is led out from the rear end of the driver 10 and passes through the second groove 22. When the cable outlet position of the driver 10 deviates from the second groove 22, the inclined surface 101 can make the cable 102 smooth to the maximum extent, reducing the interference and friction caused by the elasticity generated by the bending when the cable is routed on the covering 120. In this way, the covering position of the covering 120 can be closer to the connecting piece, saving the internal space of the sunshade device.

[0053] In the present application, the sunshade device is a device with a rotatable function and used to roll up the covering 120, such as a roller blind, a ceiling curtain, a windproof roller blind, etc. The driver 10 is a device with an output torque to directly or indirectly drive the covering 120, such as a motor. The covering 120 is an item with a shading and blocking function, such as fabric, TPU, etc.

[0054] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the scope of protection of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
