Description
Technical Field
[0001] The utility model relates to the technical field of vehicle sunshade, in particular to a sunshade curtain assembly, a glass assembly and a vehicle. Background Art
[0002] In the existing sunshade curtain structure system, in order to ensure the lightness of the sunshade curtain mounting frame, the rear crossbeam structure of the sunshade curtain is relatively simple. Figure 1 As shown, the sunshade is clamped into the rear crossbeam by the spring preload, and the motor drives the rope, which drives the slider to pull the sunshade's pull rod, and the pull rod drives the sunshade's curtain to retract and extend, thereby realizing the opening and closing of the sunshade. In the above scheme, the curtain and the rear crossbeam are usually in direct contact, such as Figure 2 As shown, in order to ensure smooth cloth discharge, the contact surface between the cloth and the rear crossbeam needs to be surface treated, that is, the contact between the cloth and the rear crossbeam is usually line contact or surface contact, and sliding friction occurs between the two.
[0003] However, the above structure has the following defects. First, due to the sliding friction between the curtain and the rear crossbeam, the motor needs a larger driving force to overcome the friction to drive the curtain to move. Second, due to the sliding friction between the curtain and the rear crossbeam, a lot of noise will be generated, and therefore the NVH (Noise, Vibration, Harshness) requirements cannot be met. Third, in the above structure, in order to prevent excessive friction, the curtain outlet angle needs to be controlled, so the product design requirements are relatively high. In addition, due to the long-term friction between the curtain and the rear crossbeam, the service life of the sunshade structure will be shortened. Utility Model Content

[0043] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.
[0044] In the existing sunshade curtain structure system, in order to ensure the lightness of the sunshade curtain mounting frame, the rear crossbeam structure of the sunshade curtain is relatively simple. Figure 1 As shown, the sunshade 20 is clamped into the rear crossbeam 30 by the spring preload force, and the motor drives the rope, which drives the slider to pull the sunshade's pull rod, and the pull rod drives the sunshade's curtain to retract and extend, thereby realizing the opening and closing of the sunshade. In the above scheme, the curtain is usually in direct contact with the rear crossbeam, such as Figure 2 As shown, in order to ensure smooth delivery of the curtain fabric, the contact surface 40 between the curtain fabric and the rear cross beam needs to be surface treated, that is, the contact between the curtain fabric and the rear cross beam is usually line contact or surface contact, and sliding friction occurs between the two.
[0045] Existing sunshade curtain assemblies have the following defects. First, due to sliding friction between the curtain and the rear crossbeam, the motor requires a greater driving force to overcome the friction and drive the curtain. Second, due to the sliding friction between the curtain and the rear crossbeam, a lot of noise is generated, and therefore the NVH requirements cannot be met. Third, in the above structure, in order to prevent excessive friction, the curtain outlet angle needs to be controlled, so the product design requirements are relatively high. In addition, due to the long-term friction between the curtain and the rear crossbeam, the service life of the sunshade curtain structure will be shortened.
[0046] Based on this, please refer to Figure 3-Figure 7 A vehicle is provided, comprising a glass assembly, the glass assembly including a sunshade assembly, which can be arranged in the vehicle's sunroof area, front windshield area, rear windshield area, or window area; the sunshade assembly includes a crossbeam 1, a shading member 2, and a rotating member 3; the crossbeam 1 has a limiting portion 11 and a supporting portion 12 arranged in sequence along a first direction, the shading member 2 and the limiting portion 11 are rotatably connected relative to each other; the rotating member 3 and the supporting portion 12 are rotatably connected relative to each other, and the rotating member 3 is distributed along a second direction; the first direction and the second direction are perpendicular to each other; in the thickness direction of the shading member 2, one side of the shading member 2 presses against the circumferential side wall of the rotating member 3, so that a first distance h is formed between the shading member 2 and the end of the crossbeam 1 near the rotating member 3; the shading member 2 can drive the rotating member 3 to rotate. Preferably, the shading member 2 is made of a flexible material with poor light transmittance.
[0047] It is worth noting that when the first direction is the width direction of the beam 1, the second direction is the length direction of the beam 1. On this basis, a third direction can also be defined. The third direction is the thickness direction of the beam 1, and the third direction is perpendicular to both the first direction and the second direction.
[0048] It can be understood that by providing the rotating member 3, the shading member 2 and the beam 1 are separated from each other, and the shading member 2 can drive the rotating member 3 to rotate during the retraction and extension process. Compared with the prior art, there is no contact between the shading member 2 and the beam 1. Therefore, the line contact or surface contact between the shading member 2 and the beam 1 (that is, the sliding friction between the shading member 2 and the beam 1) is converted into the surface contact between the shading member 2 and the rotating member 3, and the contact surface between the shading member 2 and the rotating member 3 will change with the movement of the shading member 2 (that is, the rolling friction between the shading member 2 and the rotating member 3), thereby reducing the friction resistance and friction noise during the movement of the sunshade.
[0049] In some embodiments, a mounting seat 4 is further included; the mounting seat 4 is disposed on the support portion 12, and the two ends of the rotating member 3 in the axial direction are respectively connected to a mounting seat 4 for relative rotation. By adding the mounting seat 4 to the beam 1, the rotating member 3 is connected to the beam 1 for relative rotation, thereby reducing product development costs. In addition, due to the provision of the mounting seat 4, the rotating member 3 is disposed in a space outside the beam 1, so that the light shielding member 2 and the beam 1 are separated from each other, thereby reducing frictional resistance and friction noise. Specifically, two mounting seats 4 are provided, and each end of the beam 1 has a support portion 12, and each support portion 12 is provided with a mounting seat 4.
[0050] In some embodiments, the rotating member 3 includes a roller 31 and a shaft assembly 32. A shaft assembly 32 is provided at each axial end of the roller 31, and the shaft assembly 32 is rotatably connected to the mounting base 4. Alternatively, the shaft assembly 32 may be a shaft with a hemispherical end, or a ball bearing may be provided at the end of the shaft body away from the roller 31. This configuration reduces the rotational resistance of the shaft assembly 32 and ensures smooth rotation of the rotating member 3. Preferably, the shaft assembly 32 is engaged with the mounting base 4.
[0051] In some embodiments, the limiting portion 11 has a receiving groove 111; the light shielding member 2 is at least partially embedded in the receiving groove 111. A guide portion 13 is provided between the receiving groove 111 and the roller 31, and the guide portion 13 has a guide slope 131. The receiving groove 111 is provided to accommodate the light shielding member 2. The guide portion 13 is provided to extend the receiving space of the receiving groove 111 and provide space for the assembly and rotation of the rotating member 3.
[0052] In some embodiments, the inclined direction of the guide slope 131 forms an angle α of 120° to 160° with the first direction. Specifically, in the third direction, the guide slope 131 is inclined in a direction gradually approaching the rotating member 3. The inclination of the guide slope 131 can also form a receiving groove 111 together with other parts of the crossbeam 1. Optionally, the angle α can be 130°, 131°, 132°, 133°, 134°, 135°, 136°, 137°, 138°, 139°, 140°, 145°, 150°, or 155°. Preferably, the angle α is 132°.
[0053] In some embodiments, in the first direction, a second distance d is provided between the end of the guide portion 13 distal to the receiving slot 111 and the rotating member 3. This prevents the guide portion 13 from interfering with the rotation of the rotating member 3, ensuring smooth rotation of the rotating member 3 and reducing resistance when the light shielding member 2 drives the rotating member 3. Specifically, the second distance d is the minimum distance between the end of the guide portion 13 distal to the receiving slot 111 and the circumferential sidewall of the rotating member 3. Optionally, the second distance d is between 0.5 cm and 2 cm. If the second distance d is too large, there is a certain probability that the light shielding member 2 will contact the crossbeam 1, leading to problems associated with the prior art. Preferably, the distance d is 1 cm.
[0054] In some embodiments, in the first direction, the projection of the end of the guide portion 13 away from the receiving slot 111 is located on the rotating member 3. Specifically, the end of the guide portion 13 away from the receiving slot 111 is located within a plane defined by the first and second directions. In the third direction, the rotating member 3 should always intersect this plane to prevent contact between the light shielding member 2 and the crossbeam 1. Specifically, by adjusting the positional relationship between the rotating member 3 and the guide portion 13 in the third direction, the rotating member 3 effectively supports the light shielding member 2, thereby reducing frictional resistance and friction noise. The guide portion 13 is located between the two support portions 12.
[0055] In some embodiments, optionally, the circumferential side wall of the rotating part 3 is provided with an anti-slip layer or the circumferential side wall of the rotating part 3 is a rough surface, ensuring that there is always friction between the contact surface of the shading part 2 and the rotating part 3, and the friction should be able to drive the rotating part 3 to rotate.
[0056] In some embodiments, the shading member 2 is rotatably connected to the limiting portion 11 via a winding member, and the shading member 2 is at least partially wound on the winding member. The winding member serves to store the shading member 2.
[0057] In some embodiments, the sunshade assembly further includes a frame, a motor, and a flexible shaft; the frame is connected to the crossbeam 1, and a guide rail is provided on both sides of the frame in the second direction; the end of the shading member 2 away from the winding member is slidably connected to the guide rail via a sliding assembly 10. Specifically, the sliding assembly 10 includes a pull rod and two sliders, the sliders are slidably connected to the corresponding tracks, and the two sliders are respectively connected to the two ends of the pull rod, and the end of the shading member 2 away from the winding member is connected to the pull rod. When the shading member 2 is in the reeling process or in a fully reeled state, the shading member 2 is partially wound around the outside of the winding member 5, and the rest of the part is exposed due to the traction of the pull rod. The motor is installed on the side of the crossbeam 1 away from the rotating member 3, and the motor is respectively connected to the two sliders through two flexible shafts. The motor drives the two sliders to slide on the guide rail through the flexible shaft, and the pull rod drives the shading member 2 to move under the drive of the two sliders.
[0058] The first embodiment of the present invention is:
[0059] A vehicle includes a glass assembly, which includes a sunshade assembly, which can be set in the vehicle's sunroof area, front windshield area, rear windshield area or window area; the sunshade assembly includes a crossbeam 1, a shading member 2 and a rotating member 3, the crossbeam 1 has a limiting portion 11 and a supporting portion 12 arranged in sequence along a first direction, and the shading member 2 is connected to the limiting portion 11 for relative rotation; the rotating member 3 is connected to the supporting portion 12 for relative rotation, and the rotating member 3 is distributed along a second direction; the first direction and the second direction are perpendicular to each other; in the thickness direction of the shading member 2, one side of the shading member 2 presses against the circumferential side wall of the rotating member 3, so that there is a first distance h between the shading member 2 and the end of the crossbeam 1 close to the rotating member 3; the shading member 2 can drive the rotating member 3 to rotate.
[0060] In this embodiment, the sunshade assembly further includes a frame, a motor, and a flexible shaft. The frame is connected to the crossbeam 1, and a guide rail is provided on each side of the frame in the second direction. The end of the shade member 2, which is remote from the winding member, is slidably connected to the guide rail via a sliding assembly 10. Specifically, the sliding assembly 10 includes a pull rod and two sliders, each of which is slidably connected to the corresponding track. The two sliders are respectively connected to the ends of the pull rod, and the end of the shade member 2, which is remote from the winding member, is connected to the pull rod. The motor is mounted on the side of the crossbeam 1 remote from the rotating member 3 and is connected to the two sliders via two flexible shafts.
[0061] In this embodiment, the sunshade assembly also includes a mounting base 4, which is mounted on the support portion 12. The rotating member 3 has two axially coupled ends thereof, each rotatably connected to the mounting base 4. The rotating member 3 includes a roller 31 and a rotating shaft assembly 32. A rotating shaft assembly 32 is provided at each axially coupled end of the roller 31, and the rotating shaft assembly 32 is rotatably coupled to the mounting base 4. Preferably, the rotating shaft assembly 32 is engaged with the mounting base 4 and is capable of constant rotation relative to the mounting base 4.
[0062] In this embodiment, the limiting portion 11 has a receiving groove 111; the shade member 2 is at least partially embedded in the receiving groove 111. A guide portion 13 is provided between the receiving groove 111 and the roller 31, and the guide portion 13 has a guide slope 131. When the shade member 2 is in the retracted or fully retracted state, the shade member 2 is partially located in the receiving groove 111. The inclination direction of the guide slope 131 forms an angle α of 132° with the first direction.
[0063] In this embodiment, in the first direction, a second distance d is formed between the end of the guide portion 13 away from the receiving groove 111 and the rotating member 3 , and a projection area of the end of the guide portion 13 away from the receiving groove 111 is located on the rotating member 3 .
[0064] In this embodiment, the circumferential side wall of the rotating member 3 is a rough surface.
[0065] The working principle of this embodiment is:
[0066] The motor drives two symmetrically arranged flexible shafts to move, and the flexible shafts drive the slider to slide on the guide rail. The slider drives the shading member 2 to move through the pull rod. During the movement of the shading member 2, it always presses against the circumferential side wall of the rotating member 3 and drives the circumferential side wall to rotate. In the process of movement, the shading member 2 continuously drives the rotating member 3 to rotate, which can avoid contact with the beam 1 and achieve the effect of reducing resistance.
[0067] The present invention provides a sunshade assembly and vehicle. Since the shade member 2 remains separated from the crossbeam 1 during movement, and the rotating member 3 supports the shade member 2, replacing the crossbeam 1's support for the shade member 2 in the prior art, this not only ensures that the shade member 2 is retracted and extended in a tensioned state, but also reduces the frictional resistance and friction noise during movement of the shade member 2. Since the frictional resistance during movement of the shade member 2 is reduced, the resistance during motor operation is also significantly reduced, extending the service life of the motor and the shade member 2. Furthermore, the provision of the rotating member 3 reduces the structural design requirements for the crossbeam 1. Adjusting the position of the rotating member 3 allows the shade member 2 to be positioned so that it can move while remaining in a tensioned state, reducing product design difficulty and production costs.
[0068] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the description and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
