DETAILED DESCRIPTION
[0030] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.
[0031] The embodiments of the present application are only used for explaining the present application, and are not used for limiting the scope of the present application. In the following paragraphs, the present application is described in more detail with examples referring to the drawings. It should be noted that the drawings are all in a very simplified form and all use non-precise proportions, and are only used for the purpose of conveniently and clearly assisting the description of the embodiments of the present application.
[0032] In the prior art, the sunshade curtain comprises a winding pipe, two shaft sleeves, and two fixed shafts. The two shaft sleeves are respectively connected to the two ends of the winding pipe and are respectively sleeved on the two shafts. The gap between the shaft sleeve and the shaft is zero, and the contact between the shaft sleeve and the shaft is surface contact. When the winding pipe rotates, the shaft sleeve rotates with it, and the shaft sleeve rotates around its axis.
[0033] However, the shaft inevitably has a coaxiality tolerance, which may cause the axes of the two shafts and the two shaft sleeves to be not collinear. When the axes of the two shafts and the two shaft sleeves are not collinear and have a large positional deviation, for example, the axis of one of the shafts is deviated upward by 0.5 mm from a theoretical reference axis, and the axis of the other shaft is deviated downward by 0.5 mm from the theoretical reference axis, and correspondingly, the axis of one of the shaft sleeves is deviated upward by 0.5 mm from a theoretical reference axis, and the axis of the other shaft sleeve is deviated downward by 0.5 mm from the theoretical reference axis, the shaft sleeve may not rotate smoothly on the shaft during the rotation of the winding pipe, and a resistance may be generated, that is, the coaxiality tolerance of the shaft may affect the smoothness of the rotation of the shaft sleeve.
[0034] To solve the above problems, the utility model embodiment provides a sunshade curtain and a vehicle, and the sunshade curtain and the vehicle are specifically described below.
[0035] In a first aspect, with reference to Figures 1 to 6 The sunshade curtain provided by the utility model embodiment comprises an inner winding pipe 1, two shaft sleeves 2, and two fixed shafts 3. The two shaft sleeves 2 are respectively arranged at the two ends of the inner winding pipe 1 and are respectively rotationally connected to the two fixed shafts 3. The shaft sleeve 2 rotates with the inner winding pipe 1. The fixed shaft 3 comprises a contact protrusion. The shaft sleeve 2 has an axial hole 21. Along the axial direction of the fixed shaft 3, the distance between the outer surface of the contact protrusion and the inner side wall of the axial hole 21 first decreases and then increases. The minimum distance is zero. At the minimum distance, the outer surface of the contact protrusion and the inner side wall of the axial hole 21 form circumferential line contact.
[0036] The sunshade curtain can be installed in a vehicle, and specifically can be installed on a door trim in the vehicle. The sunshade curtain is a hand-pulled sunshade curtain. The inner winding pipe 1 is wound with curtain cloth. During the opening or folding of the curtain cloth, the inner winding pipe 1 rotates, and the rotation of the inner winding pipe 1 drives the rotation of the two shaft sleeves 2. The material of the inner winding pipe 1 can be aluminum. The density of aluminum is relatively low. Under the same size, the weight of the inner winding pipe 1 is lighter when the material of the inner winding pipe 1 is aluminum, which is beneficial to reducing the weight of the sunshade curtain.
[0037] The inner winding pipe 1 is a hollow cylinder and is open at both ends along the length direction thereof. The length direction of the inner winding pipe 1 can be referred to as the axial direction of the inner winding pipe 1. Figure 1 and Figure 3The direction of the arrow in the middle. The structure of the two shaft sleeves 2 can be symmetrical, and the structure of the two fixed shafts 3 can be symmetrical. The connection mode of the shaft sleeve 2 and the inner coiled pipe 1 can be interference fit, spline fit, bonding, welding, etc. The shaft sleeve 2 is sleeved on the contact convex part of the fixed shaft 3.
[0038] The first cross section is perpendicular to the axial direction of the fixed shaft 3. The shape of the first cross section of the contact convex part is circular, and the shape of the first cross section of the inner side wall of the axial hole 21 is circumferential. The axial direction of the fixed shaft 3 can be referred to as the direction of the arrow in the middle. Figure 4 The direction of the arrow in the middle. The axial direction of the axial hole 21 is consistent with the axial direction of the shaft sleeve 2. The axial hole 21 can be non-through, or it can pass through the shaft sleeve 2 along the axial direction of the shaft sleeve 2. The inner side wall of the axial hole 21, that is, the wall surface in the circumferential direction thereof.
[0039] The distance between the outer surface of the contact convex part and the inner wall of the axial hole 21, that is, the distance between the outer surface of the contact convex part and the inner wall of the axial hole 21 along the first direction perpendicular to the axial direction of the fixed shaft 3. It should be noted that the first direction is a certain direction in the plane perpendicular to the axial direction of the fixed shaft 3. As an example, a first direction can be referred to as the direction of the arrow in the middle. Figure 4 The direction of the arrow in the middle. Figure 4 In the middle, at T1 and T2, the distance between the outer surface of the contact convex part and the inner wall of the axial hole 21 is the smallest and zero.
[0040] The fixed shaft 3 further comprises a shaft body 31, and the shape of the first cross section of the shaft body 31 is circular. As an example, the contact convex part is a spherical head 32, the diameter of the spherical head 32 is equal to the diameter of the axial hole 21, and the spherical head 32 is connected to the end of the shaft body 31. As another example, the contact convex part can be an annular convex part provided on the outer surface of the shaft body 31, the outer surface of the annular convex part is arc-shaped outwardly convex away from the shaft body 31, and the maximum diameter of the outer surface of the annular convex part is equal to the diameter of the axial hole 21.
[0041] Figure 3 In the middle, the axes of the two fixed shafts 3 are collinear, and the axes of the two shaft sleeves 2 are collinear. As an example in which the axes of the two fixed shafts 3 are not collinear and the axes of the two shaft sleeves 2 are not collinear, Figure 7 In the middle, the theoretical reference axis is L0, the axis of the fixed shaft 3 on the left side is basically consistent with the theoretical reference axis, and the axis of the fixed shaft 3 on the right side is offset upward compared with the theoretical reference axis, and the deviation is large. Correspondingly, the axis of the shaft sleeve 2 on the left side is basically consistent with the theoretical reference axis, and the axis of the shaft sleeve 2 on the right side is offset upward compared with the theoretical reference axis, and the deviation is large. Figure 4 In the middle, the two endpoints of a diameter d0 of the circumferential line contact are T1 and T2 respectively, the line connecting T1 on the left side and T1 on the right side is S1, the line connecting T2 on the left side and T2 on the right side is S2, and S1 is parallel to S2.
[0042] With reference to Figure 7 Even if the axes of the two fixed shafts 3 are not collinear and the axes of the two shaft sleeves 2 are not collinear, the two end points at any diameter of the one side circumferential line contact and the two end points at the corresponding diameter of the other side circumferential line contact can always be connected into two parallel straight lines, the center points of the two circumferential line contacts can always be connected into a straight line, and the shaft sleeve 2 can always rotate around the stable center point of the circumferential line contact, so that the shaft sleeve 2 can rotate smoothly.
[0043] It should be noted that in other examples in which the axes of the two fixed shafts 3 are not collinear and the axes of the two shaft sleeves 2 are not collinear, the axis of the left fixed shaft 3 can be offset downward compared to the theoretical reference axis with a large deviation, and the axis of the right fixed shaft 3 can be basically consistent with the theoretical reference axis. Correspondingly, the axis of the left shaft sleeve 2 can be offset downward compared to the theoretical reference axis with a large deviation, and the axis of the right shaft sleeve 2 can be basically consistent with the theoretical reference axis. In other examples in which the axes of the two fixed shafts 3 are not collinear and the axes of the two shaft sleeves 2 are not collinear, the axis of the left fixed shaft 3 can be offset downward compared to the theoretical reference axis with a large deviation, and the axis of the right fixed shaft 3 can be offset upward compared to the theoretical reference axis with a large deviation. Correspondingly, the axis of the left shaft sleeve 2 can be offset downward compared to the theoretical reference axis with a large deviation, and the axis of the right shaft sleeve 2 can be offset upward compared to the theoretical reference axis with a large deviation.
[0044] In this embodiment, the outer surface of the contact convex portion forms a circumferential line contact with the inner side wall of the axial hole 21, and when the inner tube 1 and the two shaft sleeves 2 rotate, the two shaft sleeves 2 rotate around the center point of the circumferential line contact. Whether the axes of the two fixed shafts 3 and the axes of the two shaft sleeves 2 are collinear or not, the two end points at any diameter of the one side circumferential line contact and the two end points at the corresponding diameter of the other side circumferential line contact can always be connected into two parallel straight lines, the center points of the two circumferential line contacts can always be connected into a straight line, and the shaft sleeve 2 can always rotate around the stable center point of the circumferential line contact, so that the shaft sleeve 2 can rotate smoothly and avoid a sense of obstruction, thereby improving the hand feeling when the sunshade curtain is pulled. In this embodiment, whether the axes of the two fixed shafts 3 and the axes of the two shaft sleeves 2 are collinear or not, the shaft sleeve 2 can always rotate smoothly, the rotation smoothness of the shaft sleeve 2 is not affected by the coaxiality tolerance of the fixed shaft 3, the rotation smoothness of the shaft sleeve can be avoided to be affected by the coaxiality tolerance of the shaft, the tolerance fault tolerance capability of the fixed shaft 3 and the shaft sleeve 2 is improved, and thus the qualified rate of the sunshade curtain can be improved.
[0045] In some embodiments, with reference to Figures 4 to 6The contact protrusion is a spherical head 32 connected to the shaft body 31 near the end of the inner coil pipe 1. The spherical head 32 can be a solid sphere structure or a hollow sphere structure. The diameter of the spherical head 32 is equal to the diameter of the axial hole 21. By arranging the spherical head 32, the point contact with the gasket 4 of a conventional shape can be formed on the basis of realizing the circumferential line contact with the axial hole 21 without changing the structure of the gasket 4.
[0046] In some embodiments, referring to Figure 4 and Figure 5 The gasket 4 is connected to the shaft sleeve 2, and the end of the spherical head 32 away from the shaft body 31 forms a point contact with the gasket 4.
[0047] The gasket 4 rotates with the shaft sleeve 2. The material of the gasket 4 can be rubber. The shape of the gasket 4 can be circular. The gasket 4 is used for limiting the axial movement of the shaft sleeve 2, which can prevent the axial movement of the inner coil pipe 1 and the two shaft sleeves 2 as a whole. In this embodiment, the spherical head 32 forms a point contact with the gasket 4, and the contact area between the spherical head 32 and the gasket 4 is small, which can reduce the friction between the gasket 4 and the spherical head 32 when the shaft sleeve 2 and the gasket 4 rotate, thereby improving the smoothness of the rotation of the shaft sleeve 2.
[0048] In some embodiments, referring to Figure 4 and Figure 5 The axial hole 21 has an opening, and the shaft sleeve 2 includes a shaft sleeve body 22 and an end plate 23 opposite to the opening of the axial hole 21, and the shaft sleeve body 22 and the end plate 23 enclose the axial hole 21.
[0049] The gasket 4 is connected to the end plate 23 and located in the axial hole 21. The opening of the axial hole 21 faces the end cover 7. The first cross section of the shaft sleeve body 22 is a circular ring shape, and the end plate 23 is a circular plate structure, which closes the end of the shaft sleeve 2 away from the opening of the axial hole 21. The spherical head 32 is located in the axial hole 21, and the fixed shaft 3 does not penetrate the shaft sleeve 2. The connection mode of the gasket 4 and the end plate 23 can be adhesion. In this embodiment, the end plate 23 provides a larger connection surface for the gasket 4, which can improve the fixing effect of the gasket 4.
[0050] In some embodiments, referring to Figure 5 The shaft sleeve body 22 includes a protruding section 221 and a fitting section 222, and the fitting section 222 is located in the inner coil pipe 1 and is in interference fit with the inner coil pipe 1. The protruding section 221 is located on one side of the inner coil pipe 1 along the length direction of the inner coil pipe 1 and is in contact with the end face of the inner coil pipe 1.
[0051] The end plate 23 is connected to the end of the fitting section 222 away from the protruding section 221. The outer diameter of the protruding section 221 is greater than the outer diameter of the fitting section 222. The outer surface of the fitting section 222 can be provided with a plurality of barb structures that are in interference fit with the inner wall of the inner tube 1. When the shaft sleeve 2 is installed, the fitting section 222 extends into the end of the inner tube 1 until the protruding section 221 is in contact with the end surface of the inner tube 1, indicating that the shaft sleeve 2 is installed in place. In this embodiment, the protruding section 221 is provided, which can be used to confirm whether the shaft sleeve 2 is installed in place, and can prevent the inner tube 1 from moving relative to the shaft sleeve 2 along the axial direction.
[0052] In some embodiments, referring to Figures 2 to 4 , the sunshade curtain further comprises a housing 8 and two end covers 7, the inner tube 1 is located in the housing 8, and the two end covers 7 are respectively detachably connected to the two ends of the housing 8. The two fixed shafts 3 are respectively connected to the two end covers 7.
[0053] The material of the housing 8 is aluminum. Aluminum is a light and corrosion-resistant metal. The density of aluminum is relatively low, and the weight of the housing 8 made of aluminum is lighter than that of the housing 8 made of other materials, which is beneficial to reduce the weight of the sunshade curtain. The end cover 7 can be connected to the housing 8 by a screw 9. A single end cover 7 can be connected to the housing 8 by one screw 9, two screws 9 or three screws 9. A single end cover 7 is preferably connected to the housing 8 by two screws 9. In this embodiment, the two end covers 7 are respectively detachably connected to the two ends of the housing 8, which is beneficial to the replacement and maintenance of the inner tube 1 and the shaft sleeve 2 inside.
[0054] In some embodiments, referring to Figure 4 and Figure 5 , the fixed shaft 3 and the end cover 7 are in a split structure and are detachably connected. When the fixed shaft 3 and the end cover 7 are in a split structure, they are manufactured separately and then connected together. The connection mode of the fixed shaft 3 and the end cover 7 can be connection by a threaded locking piece 6, threaded connection, clamping, etc. In this embodiment, the fixed shaft 3 and the end cover 7 are detachably connected, and when the fixed shaft 3 is worn, only the fixed shaft 3 needs to be replaced, which can reduce the maintenance cost of the sunshade curtain.
[0055] In other embodiments, the fixed shaft 3 and the end cover 7 are in a split structure and are fixedly connected. The connection mode of the fixed shaft 3 and the end cover 7 can be adhesion, welding, etc.
[0056] In other embodiments, the fixed shaft 3 and the end cover 7 can also be in an integrated structure.

The shaft body 31 passes through the through hole, and the threaded segment 311 is threadedly connected with the threaded locking piece 6. The threaded locking piece 6 can be a nut. The threaded locking piece 6 is located on the outer side of the end cover 7 away from the inner tube 1. The length of the threaded segment 311 is greater than the thickness of the nut and less than or equal to the length of the shaft body 31. In the embodiment, the connection between the fixed shaft 3 and the end cover 7 is a threaded connection, and the connection is reliable.
[0058] In some embodiments, with reference to Figure 4 and Figure 5 The spherical head 32 is provided with a side plane 321 connected with the shaft body 31. The sunshade curtain further comprises a gasket 5, and the gasket 5 is sleeved on the shaft body 31 and located between the end cover 7 and the side plane 321.

In the embodiment, when the threaded locking piece 6 is locked, the gasket 5 is compressed, and the two sides of the gasket 5 abut against the side plane 321 and the mounting portion 71 respectively, so that the threaded connection between the threaded segment 311 and the threaded locking piece 6 is prevented from loosening.
