Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sunshade equipment, in particular to a sunshade equipment with a cover shell connected in rotation. BACKGROUND

[0002] The sunshade equipment can prevent wind and rain because it has a cover shell with a shelter and a shade, and the cover shell comprises a main shell body and a secondary shell body. The main shell body and the secondary shell body are fixed by mounting codes and screws. Since the cover shell needs to be connected and fastened with components such as mounting codes and fabrics, the connection and fastening will limit the setting position and space of the connected components inside the cover shell. In the related art, the assembly positioning and limiting of the cover shell are not considered, the service life of the mold cannot make the winding components inside the cover shell have the maximum winding space, and space is wasted. CONTENT OF THE UTILITY MODEL

[0003] The application provides a sunshade equipment with a cover shell connected in rotation, which is used for improving the connection and fastening of the cover shell of the sunshade equipment, so that the position of the connection and fastening of the cover shell can make the winding space inside the cover shell be most reasonably utilized, and the service life of the mold is improved. The embodiments of the application include the following solutions.

[0004] In a first aspect, the application provides a cover shell connected in rotation, which comprises a main shell body and a secondary shell body. The main shell body comprises a circular-arc notch, a C-shaped groove, a first surface, a second surface, a third surface, a fourth surface, a fifth surface, a sixth surface and a seventh surface. The secondary shell body comprises a circular-arc flange, an eighth surface, a ninth surface, a tenth surface, an eleventh surface and a first flange. The profile center of the circular-arc notch coincides with the profile center of the circular-arc flange. The first surface is parallel to the second surface, the third surface is parallel to the fourth surface, the fifth surface is perpendicular to the first surface, the sixth surface is parallel to the seventh surface and perpendicular to the third surface, the eighth surface is parallel to the ninth surface and coincides with the fifth surface, and the tenth surface is parallel to the eleventh surface and perpendicular or close to perpendicular to the ninth surface (close to perpendicular means that the angle between the two surfaces is within 85-90 degrees).

[0005] In the implementation, the profile centers of the circular-arc notch and the circular-arc flange coincide, and the circular-arc notch and the circular-arc flange are several concentric circular arcs, so that the circular-arc notch and the circular-arc flange have the functions of rotation limiting and mounting. In this way, the main shell body and the secondary shell body can rotate relative to each other and the movement position between them is limited.

[0006] The parallel and perpendicular relationships between the above-mentioned surfaces make the cover shell be prepared by a processing mode of mold extrusion, so that the cover shell can be processed according to the carrying length of a transport tool, the cover shell can be made very long, and the waste of materials caused by secondary processing or more is reduced.

[0007] In one implementation, the circular-arc slot and the circular-arc flange are a pair of connecting combinations, and the circular-arc slot and the circular-arc flange are arranged on the main shell or the auxiliary shell. When the circular-arc slot is arranged on the main shell, the circular-arc flange needs to be arranged on the auxiliary shell, and vice versa. In this way, the internal space of the sunshade device can be reasonably utilized, and interference between the assemblies can be avoided.

[0008] In one implementation, the main shell is provided with a plurality of C-shaped slots, and the C-shaped slots are arranged between the edges of the main shell outside the quadrant points of the tangent circle at the center of the profile of the main shell and the vertices of the main shell. The C-shaped slots are used for mounting the connecting and fastening of the code. In this way, the winding assembly placed in the cover shell will not interfere with the C-shaped slots when it is wound to the maximum volume, and the maximum space of the cover shell can be reasonably utilized, so that more fabric can be wound.

[0009] In a second aspect, the application provides a sunshade device, which comprises a winding assembly and the cover shell provided in any of the implementations described above, and the cover shell is used for shading and covering the winding assembly in the sunshade device.

[0010] The sunshade device provided by the application uses the cover shell provided by the first aspect of the application to shade and cover the winding assembly. Because the cover shell in the application has reasonable position settings for rotation limiting and mounting code connection, the winding volume of the winding assembly is increased, the space of the cover shell is reasonably utilized, and easy installation and limiting are achieved.

Similarly, the definitions of the X, Y, and Z directions are also applicable to the various drawings to be described later. It should be noted that the above definitions of the X, Y, and Z directions are only for the convenience of describing the positional relationship and connection relationship between the various components in the embodiments of the present application, and should not be understood as a limitation of the embodiments of the present application.

[0030] Please refer to Figures 1-8 , a cover shell comprising a main shell 1, a secondary shell 2, wherein the main shell 1 comprises a circular arc notch 11, a C-shaped groove 12, a first face 21, a second face 22, a third face 23, a fourth face 24, a fifth face 25, a sixth face 26, a seventh face 27; the secondary shell 2 comprises a circular arc flange 30, an eighth face 38, a ninth face 39, a tenth face 40, an eleventh face 41, a third flange 63, a fourth flange 64; the profile center of the circular arc notch 11 coincides with the profile center of the circular arc flange 30, the first face 21 is parallel to the second face 22, the third face 23 is parallel to the fourth face 24, the fifth face 25 is perpendicular to the first face 21, the sixth face 26 is parallel to the seventh face 27 and perpendicular to the third face 23, the eighth face 38 is parallel to the ninth face 39 and coincides with the fifth face 25, the tenth face 40 is parallel to the eleventh face 41 and perpendicular or close to perpendicular to the ninth face 39 (close to perpendicular means that the angle between the two faces is within 90 degrees plus or minus 5 degrees).

[0031] In some embodiments, the material of the main shell 1 and the secondary shell 2 is aluminum alloy or PVC, which is prepared by a mold extrusion process, so that the length of the cover shell can be made very long, ensuring that the shape and position tolerances between the planes are small. Because the cover shell needs to be cut again according to the size of the window during the processing of the finished product of the sunshade device, and the cover shell is inconvenient to use in actual application. Therefore, the longer the cover shell is, the higher the utilization rate of the secondary or even multiple cutting will be, reducing the waste of materials. For example Figure 1 As shown, the figure is a side view schematic diagram of the assembly external structure of an embodiment of the cover shell, wherein the main shell 1 and the secondary shell 2 can be extruded to a very long length along the Z-axis. In this embodiment, the length of the cover shell is not defined, and it can be extruded to any size along the Z-axis by a mold and then cut again or multiple times. For example, in order to meet the loading of transportation tools such as trucks, the extrusion length of the cover shell is 6.7 meters.

[0032] In some embodiments, the main housing 1 or the auxiliary housing 2 is provided with several C-shaped grooves 12 for connecting and fastening with the mounting codes. In the present embodiment, the number of C-shaped grooves is not limited, which can be 2, 3, 4 or even more. They are arranged at the positions between the quadrant points of the circle with the center at the profile center of the cover and tangent to the three faces of the cover and the vertices of the main housing, and are placed in a triangular shape. Such design can maximize the use of the internal space of the cover, so that the winding assembly 80 installed in the cover can wind more fabric 60, and the cover can be more reliable when connected and fastened. For example, please refer to Figures 2-4 , the dashed circle 3 in the figure (the dashed circle is the construction circle) is tangent to two faces of the main housing 1 and the auxiliary housing 2 respectively, and the diameter of the dashed circle 3 is the maximum diameter of the fabric 60 in the winding assembly 80. The number of C-shaped grooves in the present embodiment is 3. The C-shaped grooves are arranged at the edges of the main cover 1 in a triangular shape, which also improves the stability of the connection between the main housing 1 and the mounting code 59, so that it is not easy to deform. For example, the mounting code 59 is connected with the C-shaped groove 12 of the main housing 1 through the self-tapping screw 58.

[0033] In some embodiments, the C-shaped groove 12 also includes positioning and guiding functions. In combination with the above embodiment, the C-shaped groove 12 is arranged at the second flange 52, and the second flange 52 makes the outer edge surface of the C-shaped groove 11 tangent to the dashed circle 3. During the winding process of the fabric 60, the fabric 60 placed below is parallel to the Y direction due to the influence of gravity, and when the position of the fabric 60 during winding exceeds the position of the first quadrant point 53 of the C-shaped groove (the first quadrant point 53 is referenced to the circular arc surface of the outer edge of the C-shaped groove, and the position exceeding the C-shaped groove is the position from the first quadrant point 53 to the fourth face 24), the C-shaped groove 11 contacts the fabric, so that the fabric 60 placed below can adjust its placement position (as shown in Figure 4 , the most ideal working position of the fabric 60 is parallel to the Y direction and enters the guide rail 61 from the center of the guide rail 61), which reduces the friction of the guide rail 61 on the fabric. The C-shaped groove 12 plays a positioning and guiding role.

[0034] In some embodiments, the opening direction of the C-shaped groove 11 should consider the service life of the mold and the working position of the internal components, and the opening direction should be connected to the main mold core as much as possible to avoid the flange of part of the cavity of the mold core being too thin and easy to be damaged. For example, please refer to Figure 5 , the mold core 66 of the main housing is shown in the figure, and the opening of one of the C-shaped grooves 12 is close to the outer edge of the circular arc groove in the X direction, so that the fifth flange 65 of the mold core 66 will not be too thin at this position, which increases the service life of the mold. Please refer back to Figure 2 、 Figure 4The opening of the C-shaped groove 12 on the second flange 52 is arranged at an angle of 43 degrees with the Y axis. This arrangement can prevent the fabric 60 from rubbing against the opening of the C-shaped groove when it is being lowered. In this embodiment, the angle of the opening of the C-shaped groove 12 is exemplary only. It can also be arranged at other angles as long as it does not rub against the fabric 60.

[0035] In some embodiments, the cover further comprises a third flange 63 and a fourth flange 64. The ends of the third flange 63 and the fourth flange 64 are arc-shaped and / or spherical, and can also be C-shaped grooves. They have the functions of limiting, guiding, and / or connecting and fastening. Please refer to Figures 2-4 The third flange 63 is arranged on the secondary housing 2, and the fourth flange 64 is arranged on the primary housing 1. The fabric 60 is wound between the third flange 63 and the fourth flange 64. The third flange 63 and the fourth flange 64 restrict the position of the fabric 60 in the X direction, reducing the change in the position of the fabric 60 when it is lowered vertically and raised, thereby reducing the friction between the fabric and the guide rail 61.

[0036] In some embodiments, please refer to Figures 6-8 The first flange 50 is further arranged on the secondary housing 2. After being connected with the mounting code 5, the first flange 50 can limit the rotation of the secondary housing 2 around the Z axis. The ninth face 39 and the tenth face 40 of the secondary housing 2 are perpendicular or close to perpendicular. The close-to-perpendicular relationship can provide an interference rebound elastic force for the first flange 50, so that the connection of the first flange 50 can be more secure. Exemplarily, the angle between the ninth face 39 and the tenth face 40 is 89.5 degrees. The tenth face 40 is connected with the mounting code 5 of the secondary cover 2, and the mounting code 5 is provided with a first recess 55. The slot of the first recess 55 is perpendicular to the tenth face 40. The thirteenth face 57 is parallel to the X face and horizontal to the first corner point 56 (without considering the mold angle and reasonable shape and position tolerance). The distance from the thirteenth face 57 to the edge line 58 is equal to the distance from the tenth face 40 to the eleventh face 41. When the first flange 50 is connected with the first recess 55, the tenth face 40 will have an interference deformation of 0.5 degrees with the thirteenth face 57, so that the secondary housing 2 is deformed to generate an elastic tension to secure the secondary housing 2 and the mounting code 5. After being connected by the tension, the secondary housing 2 cannot rotate around the Z direction.

[0037] In some embodiments, the circular arc slot 11 and the circular arc flange 30 are composed of several circular arcs. The profile center of the circular arc slot 11 coincides with the profile center of the circular arc flange 30. When the primary housing 1 is completely fixed by the mounting code 5, the circular arc flange 30 of the secondary housing 2 can be rotated and installed around the Z axis after being inserted into the circular arc slot 11. The circular arc slot 11 also limits the linear motion of the secondary housing 2 in the X and Y directions. Exemplarily, please refer to Figures 6-8, the first arc 71, the second arc 72, the third arc 73, the fourth arc 74 and the fifth arc are coaxial or close to coaxial, and the arc flange 30 and the arc notch 11 are in clearance fit. When the main shell is completely fixed, after the arc flange 30 and the arc notch 11 are connected, the freedom of movement of the secondary shell 2 in the X and Y directions is fixed, and the secondary shell 2 can only rotate around the Z axis. In this way, the convenience and reliability of the secondary shell 2 during installation and connection can be improved.

[0038] It should be understood that in the above embodiments, close to coaxial refers to the concentricity tolerance between the arcs, which can be adjusted according to the clearance of the clearance fit between the arc flange 30 and the arc notch 11. The larger the clearance, the lower the accuracy requirement of the coaxial center, and the smaller the clearance, the higher the accuracy requirement of the coaxial center.

[0039] A sunshade device includes a winding assembly 80, a fabric 60, the winding assembly 80 refers to a winding assembly that can rotate to wind and unwind the fabric 60 (such as PVC, PTU, cloth, etc. with the function of shading and blocking), and the winding assembly 80 is exemplarily, Figure 3 , Figure 4 , Figure 7 A sunshade device is shown, which is a windproof roller blind, and the sunshade device uses the cover of the application to cover and block the winding assembly 80.

[0040] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the scope 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 also intends to include these modifications and variations.
