Description

Car window sunshade structure and vehicle Technical Field

[0001] This utility model relates to the field of vehicle parts technology, and in particular to a window sunshade structure. It also relates to a vehicle equipped with the window sunshade structure. Background Technology

[0002] With the increasing demand for vehicle passenger comfort, side window sunshades have become an important feature for enhancing the driving and riding experience. Therefore, many vehicles on the market today are equipped with side window sunshades to effectively block sunlight and create a comfortable riding environment for passengers.

[0003] However, when the existing sunshade is closed, there is a large gap between the sunshade and the door trim panel, which ruins the overall aesthetics of the vehicle interior, reduces the vehicle's refinement and visual appeal, makes it difficult to meet consumers' requirements for the refinement of the vehicle's appearance, and lowers the overall quality of the vehicle. Summary of the Invention

[0004] In view of this, the present invention aims to propose a window sunshade structure to improve the sense of refinement of the vehicle interior when the sunshade is closed.

[0005] To achieve the above objectives, the technical solution of this utility model is implemented as follows:

[0006] A car window sunshade structure includes a sunshade curtain mounted on the car door via a roll-up mechanism. One end of the sunshade curtain is provided with a pull rod arranged along the width direction of the sunshade curtain, and a blocking mechanism is provided at the pull rod.

[0007] The pull rod is connected to the drive mechanism on the car door to pull the sunshade to open or close;

[0008] The sunshade mechanism includes a baffle rotatably mounted on the pull rod and an elastic part disposed between the baffle and the pull rod. When the sunshade is closed, the baffle can abut against the upper trim panel in the door and flip away from the pull rod to block the gap between the pull rod and the upper trim panel.

[0009] Furthermore, the upper trim panel is provided on both the inner and outer sides of the vehicle door, and a baffle is provided corresponding to the upper trim panel on both sides. When the sunshade is closed, each baffle abuts against the upper trim panel on the same side; and / or,

[0010] The top surface of the upper trim panel slopes downwards in a direction away from the sunshade.

[0011] Furthermore, the elastic part includes a spring with one end disposed on the pull rod, and the spring is disposed along the length of the pull rod;

[0012] The baffle includes a baffle body and a pull wire disposed on the baffle body, and the baffle is connected to the other end of the spring through the pull wire.

[0013] Furthermore, the springs are two located at both ends of the pull rod along its length.

[0014] The pull wire extends along the length of the baffle body, and both ends of the pull wire are connected to the two springs respectively.

[0015] Furthermore, the pull rod is provided with a receiving groove for accommodating the spring, and a through hole extending to the end of the pull rod;

[0016] The opening of the receiving groove faces the baffle, the through hole communicates with the receiving groove, and the pull wire passes through the through hole.

[0017] Furthermore, the baffle is provided with a mounting protrusion that protrudes toward the pull rod side;

[0018] Under the action of the elastic part, the mounting protrusion abuts against the pull rod, and the baffle tilts from top to bottom toward the side away from the pull rod.

[0019] Furthermore, the top of the pull rod is provided with a notch, and a mounting shaft is provided in the notch;

[0020] The top of the baffle is provided with a mounting ring that protrudes toward the pull rod, and the mounting ring has a notch, through which the mounting ring is fitted onto the mounting shaft.

[0021] Furthermore, each end of the pull rod is provided with a sliding rod, which is slidably mounted on the door along the vertical direction of the vehicle and connected to the drive mechanism;

[0022] The two ends of the pull rod are respectively hinged to the corresponding slide rods.

[0023] Furthermore, at least one end of the pull rod is provided with a spacing adjustment part between it and the corresponding end of the slide rod, the spacing adjustment part being used to adjust the spacing between the two in the longitudinal direction of the vehicle.

[0024] Compared with the prior art, this utility model has the following advantages:

[0025] (1) The sunshade structure of the car window described in this utility model is provided with a pull rod arranged along its width direction at one end of the sunshade curtain and a blocking mechanism. When the sunshade curtain is closed, the baffle can abut against the upper trim panel of the car door and flip up to block the gap between the pull rod and the upper trim panel. This can effectively block the structure inside the upper trim panel. Thus, it can effectively avoid the problem of a large gap between the sunshade curtain and the upper trim panel in the prior art, and can improve the aesthetics and refinement of the vehicle interior.

[0026] (2) By installing upper trim panels on both the inner and outer sides of the car door and corresponding baffles, when the sunshade is closed, each baffle abuts against the upper trim panel on the same side, which can block the gap on both sides of the car door, so that the car window has a better aesthetic appeal when viewed from the inner side, and can further enhance the overall aesthetics and refinement of the vehicle's interior and exterior.

[0027] (3) By including a spring on the pull rod as the elastic part, and including a baffle body and a pull cable as the baffle, and connecting the baffle to the spring via the pull cable, the structure is not only simple and easy to design and implement. Moreover, when the baffle abuts against the upper trim panel of the door, the elastic deformation of the spring can effectively ensure that the baffle is always in close contact with the upper trim panel, thereby improving the blocking effect. In addition, the cooperation between the spring and the pull cable can make the baffle evenly stressed during the flipping process, avoiding the baffle tilting or jamming caused by local stress concentration, and making the movement of the baffle smoother and more stable.

[0028] (4) By setting a spring at each end of the length of the pull rod, when the baffle abuts against the upper trim panel, the springs at both ends provide elastic force synchronously, which helps to ensure that the baffle is subjected to uniform force along the length direction and avoids the baffle from tilting or jamming due to force on one side. This can effectively eliminate gaps or tilting caused by uneven force and further improve the blocking effect.

[0029] (5) A receiving groove is provided on the pull rod to accommodate the spring, which can hide the spring inside the groove, avoiding the spring component from affecting the overall aesthetics of the sunshade and interfering with other components. Extending the through hole to the end of the pull rod and connecting it with the receiving groove, and threading the pull cable through the through hole, can avoid transmission failure caused by pull cable deviation or shaking during movement, and help ensure that the elastic force of the spring is well transmitted to the baffle through the pull cable. Moreover, there is no need to set additional guide rails for the pull cable in other positions of the door, which simplifies the structure and facilitates design and implementation.

[0030] (6) By setting a mounting protrusion on the baffle, and under the action of the elastic part, the baffle tilts from top to bottom away from the pull rod. This structure allows the top of the baffle to fit tightly against the pull rod, reducing the gap between them. Moreover, when the baffle abuts against the upper trim panel, it helps the baffle to flip outward to better cover the gap between the pull rod and the upper trim panel, thereby effectively ensuring the refinement of the vehicle interior.

[0031] (7) By setting a notch and mounting shaft at the top of the pull rod, and setting a mounting ring with a notch at the top of the baffle, the top of the baffle can be tightly abutted against the pull rod, which can effectively reduce the gap between the two. At the same time, it can also cover the pull rod, which can effectively prevent the sunshade from being exposed and help to ensure the refinement of the vehicle interior. Moreover, the notch design makes it easy to quickly disassemble and replace the baffle during after-sales maintenance, and the structure is simple and easy to design and implement.

[0032] (8) By setting sliding rods at both ends of the pull rod, it is beneficial to ensure that the two ends of the pull rod move synchronously when it is opened or closed, avoiding problems such as skewing, jamming or uneven rolling of the sunshade caused by uneven force on one side. Furthermore, by making the two ends of the pull rod hinged to the corresponding sliding rods, it is possible to effectively avoid problems such as deformation of the front sunshade due to uneven force during the raising and lowering process.

[0033] (9) By setting a spacing adjustment part, the installation tolerance between the two slide rods can be compensated, thereby ensuring the opening or closing effect of the sunshade.

[0034] Another objective of this utility model is to provide a vehicle equipped with the window sunshade structure described above.

[0035] The vehicle described in this utility model, by setting the window sunshade structure as described above, not only has a sunshade effect when the sunshade is open, but also, when the sunshade is closed, the baffle can abut against and flip against the upper trim panel of the door, thus blocking the gap between the pull rod and the upper trim panel. This can better cover the structure on the inside of the upper trim panel, thereby making the vehicle interior more aesthetically pleasing and refined, which helps to improve the overall quality of the vehicle.

[0068] Furthermore, in the description of this utility model, unless otherwise explicitly defined, the terms "installation," "connection," "joining," and "connector" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model in light of the specific circumstances.

[0069] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0070] In existing technologies, when the vehicle sunshade 1 is closed, a portion of the sunshade 1 is exposed, and there are significant gaps between the sunshade 1 and the door trim panel, reducing the vehicle's refined appearance and visual appeal, and failing to meet consumers' higher demands for a more sophisticated vehicle exterior. Therefore, this embodiment proposes a novel window sunshade structure, including a sunshade 1 mounted on the door via a roll-up mechanism.

[0071] The sunshade 1 has a pull rod 2 at one end, which is arranged along the width of the sunshade 1, and a blocking mechanism is provided at the pull rod 2. The pull rod 2 is connected to a drive mechanism on the door to pull the sunshade 1 to open or close. The blocking mechanism includes a baffle 3 rotatably mounted on the pull rod 2 and an elastic part between the baffle 3 and the pull rod 2. When the sunshade 1 is closed, the baffle 3 can abut against the upper trim panel 4 in the door and flip away from the pull rod 2, thus blocking the gap between the pull rod 2 and the upper trim panel 4.

[0072] In this embodiment, the window sunshade structure has a pull rod 2 arranged along the width direction at one end of the sunshade 1, and a blocking mechanism is provided. When the sunshade 1 is closed, the baffle 3 can abut against and flip against the upper trim panel 4 of the door, thus blocking the gap between the pull rod 2 and the upper trim panel 4, thereby blocking the internal structure of the upper trim panel 4. This effectively avoids the problem of a large gap between the sunshade 1 and the upper trim panel 4 in the prior art, and can improve the aesthetics and refinement of the vehicle interior.

[0073] Based on the above design concept, an exemplary structure of the vehicle window sunshade structure in this embodiment is shown in Figures 1 to 11. The retractable mechanism is located on the vehicle door, and its structure and specific arrangement are the same as in the prior art. Furthermore, as shown in Figure 7, the retractable mechanism generally includes a retractable housing 10 located on the vehicle door, a roller located within the retractable housing 10, and a torque component (such as a torsion spring or spiral spring 11) that provides power for retracting. The top of the retractable housing 10 has an opening for the sunshade curtain 1 to extend from. One end of the sunshade curtain 1 is connected to the roller, and the torque component is connected to the roller to drive the roller to rotate and retract the curtain. This embodiment does not improve the retractable mechanism; its more detailed structure can be referred to in the prior art. Additionally, the sunshade curtain 1 can also adopt a conventional structure, such as mesh fabric or other structures, which will not be described in detail here.

[0074] As a further implementation, as shown in Figures 1 and 12, upper trim panels 4 are provided on both the inner and outer sides of the door, and corresponding to the upper trim panels 4 on both sides, baffles 3 are provided. When the sunshade 1 is closed, each baffle 3 abuts against the upper trim panel 4 on the same side. This arrangement can cover the gaps on both sides of the door. Compared to covering only one side, this allows the window area to have a more refined appearance when viewed from different angles, both inside and outside, which helps to enhance the overall aesthetics of the vehicle's interior and exterior.

[0075] For ease of explanation, the outer upper trim panel 4 is referred to as "first trim panel 401," and the inner upper trim panel 4 is referred to as "second trim panel 402." The first trim panel 401 has a receiving groove K and covers one side of the retractable housing 10 and the drive mechanism. Furthermore, for better shading and aesthetics, the top surface of the upper trim panel 4 is inclined downwards in the direction away from the sunshade 1. This design allows the upper trim panel 4 to smoothly flip outwards as the sunshade 1 rolls down, guided by the top surface of the upper trim panel 4, when the baffle 3 abuts against it, effectively preventing the baffle 3 from jamming during flipping. Referring to Figures 11 and 12, the top surfaces of both the first trim panel 401 and the second trim panel 402 are inclined downwards.

[0076] Referring to Figures 13 and 14, in this embodiment, the pull rod 2 extends along the width direction of the sunshade curtain 1. Furthermore, to facilitate the connection between the pull rod 2 and the sunshade curtain 1, the pull rod 2 in this embodiment includes an outer rod body 2a and an inner rod body 2b. After the outer rod body 2a and the inner rod body 2b clamp the sunshade curtain 1, they are welded together. Additionally, the two baffles 3 are rotatably connected to the outer rod body 2a and the inner rod body 2b, respectively. It should be noted that the pull rod 2 can also be an integral structure, or other structures, as long as it can connect the sunshade curtain 1 to the pull rod 2.

[0077] In a preferred embodiment, the elastic part of this embodiment includes a spring 11 with one end attached to the pull rod 2, and the spring 11 is arranged along the length of the pull rod 2. Furthermore, the baffle 3 includes a baffle body 301 and a pull wire 302 provided on the baffle body 301, and the baffle 3 is connected to the other end of the spring 11 via the pull wire 302. By arranging the spring 11 along the length of the pull rod 2, a more uniform elastic force can be provided during the opening or closing of the sunshade 1. When the baffle 3 abuts against the upper trim panel 4, the elastic deformation of the spring 11 helps ensure that the baffle 3 always fits tightly against the upper trim panel 4, thereby improving the shading effect of the shading mechanism.

[0078] The design of the baffle 3 being connected to the spring 11 via the pull wire 302, compared to the traditional rigid linkage structure, allows for easier arrangement in complex spatial paths, simplifying design and implementation. Simultaneously, the flexibility of the pull wire 302 buffers movement impacts, reduces mechanical wear, and extends the service life of the sunshade structure. Specifically, the pull wire 302 can be made of stainless steel to provide good structural strength and a longer service life.

[0079] As a further embodiment, referring to Figure 15, in this embodiment, there are two springs 11 located at both ends of the pull rod 2 along its length. Furthermore, a pull wire 302 extends along the length of the baffle body 301, and both ends of the pull wire 302 are connected to the two springs 11 respectively. In this embodiment, by providing one spring 11 at each end of the pull rod 2 along its length, a symmetrical elastic support structure can be formed. When the baffle 3 abuts against the upper trim panel 4, the springs 11 at both ends can simultaneously provide elastic force, which helps to ensure that the baffle 3 is subjected to uniform force along its length, avoiding skewing or localized wear of the baffle 3 due to unilateral force, thereby improving the smoothness of the baffle 3's rotation and ensuring the effective blocking of gaps.

[0080] In addition, even if one of the springs 11 fails, the other spring 11 can still undergo elastic deformation so that the baffle 3 can perform its shading function, reducing the risk of system failure due to the failure of a single component, extending the overall service life of the sunshade structure, improving product reliability, and reducing after-sales maintenance costs.

[0081] In this preferred embodiment, as shown in Figure 16, the pull rod 2 is provided with a receiving groove K for accommodating the spring 11, and a through hole P extending to the end of the pull rod 2. The opening of the receiving groove K faces the baffle 3, and the through hole P communicates with the receiving groove K, through which the pull wire 302 passes. The receiving groove K is an elongated groove extending along the length of the pull rod 2. Furthermore, to facilitate the connection between the spring 11 and the pull rod 2, as shown in Figure 16, the pull rod 2 is provided with a fixing block protruding into the receiving groove K. One end of the spring 11 is hooked onto this fixing block, and the other end is connected to the pull wire 302.

[0082] This design allows the spring 11 to be concealed within the receiving groove K, preventing it from affecting the overall aesthetics of the sunshade 1. Consequently, when the sunshade 1 is opened or closed, the spring 11 moves within the receiving groove K, and only the baffle 3 and the sunshade 1 itself are visible from the outside, thus enhancing the cleanliness and sophistication of the door interior.

[0083] Extending the through hole P to the end of the pull rod 2 and connecting it with the receiving groove K provides a clear path for the pull cable 302. Simultaneously, it effectively prevents transmission failure caused by offset or wobbling during movement, ensuring that the elastic force of the spring 11 is effectively transmitted to the baffle 3 via the pull cable 302. Furthermore, the integrated design of the receiving groove K and the through hole P eliminates the need for additional guide rails in other parts of the door, simplifying the structure and facilitating design and implementation.

[0084] To achieve better usability, the baffle 3 is provided with a mounting protrusion 303 protruding towards the pull rod 2. Under the action of the elastic part, the mounting protrusion 303 abuts against the pull rod 2, causing the baffle 3 to tilt from top to bottom away from the pull rod 2. The advantage of this design is that it allows the top of the baffle 3 to abut tightly against the pull rod 2, reducing the gap between them. Moreover, when the baffle 3 abuts against the upper trim panel 4, it helps the baffle 3 to flip outward, better concealing the gap between the pull rod 2 and the upper trim panel 4, thereby effectively ensuring the refinement of the vehicle's interior.

[0085] Specifically, referring to Figures 17 and 18, the mounting protrusions 303 are located approximately at the center of the width of the baffle body 301, and are multiple protrusions spaced apart along the length of the baffle body 301. This further improves the contact stability between the baffle 3 and the pull rod 2, helps ensure the tilted state of the baffle 3, and thus facilitates the outward flipping of the baffle 3 when it contacts the upper trim panel 4.

[0086] Here, as a further embodiment, based on the above description, in order to facilitate the installation of the pull wire 302 on the baffle body 301, each mounting protrusion 303 is provided with a through hole that extends through the length of the baffle body 301. The pull wire 302 is then inserted into the through hole of each mounting protrusion 303, thereby realizing the installation of the pull wire 302 on the baffle body 301.

[0087] At this point, in order to improve the uniformity of the traction of the pull cable 302 on the baffle body 301, as shown in Figure 17, mounting protrusions 303 are respectively provided at both ends of the baffle body 301 along its length. This ensures that the pull cable 302 runs through the entire length of the baffle body 301, which helps improve the uniformity of the traction on the baffle body 301. This allows for better traction of the baffle 3 to flip and return to its original position, thus better ensuring the baffle 3 effectively conceals the gap between the pull rod 2 and the upper trim panel 4, maintaining the overall refinement of the vehicle's interior.

[0088] It should be noted that the elastic part may include not only the spring 11 and the pull wire 302 connected to the spring 11, but may also include the spring 11 and the elastic band connected to the spring 11.

[0089] Furthermore, continuing to refer to Figures 17 and 18, in a preferred embodiment, the top of the pull rod 2 is provided with a notch 201, and a mounting shaft 202 is provided in the notch 201. Additionally, the top of the baffle 3 is provided with a mounting ring 304 protruding towards the pull rod 2, and a notch is provided on the mounting ring 304, through which the mounting ring 304 is fitted onto the mounting shaft 202.

[0090] Here, by providing a notch 201 and a mounting shaft 202 at the top of the pull rod 2, and a mounting ring 304 with a notch at the top of the baffle 3, the top of the baffle 3 can be tightly abutted against the pull rod 2, effectively reducing the gap between them. Simultaneously, it also provides cover for the pull rod 2, solving the problem of partial exposure of the sunshade 1 when closed in the prior art, thus improving the refinement of the vehicle interior. Furthermore, the notch design facilitates quick disassembly and replacement of the baffle 3 during after-sales maintenance, and the simple structure makes it easy to design and implement.

[0091] Referring to Figures 16 and 18, in this embodiment, the notch 201 and the mounting shaft 202 are located at the corner of the top of the pull rod 2 and are elongated strips extending along the length of the pull rod 2, thereby improving the installation stability of the baffle 3. As a further embodiment, referring to Figure 15, multiple notches 201 and mounting shafts 202 are spaced apart along the length of the pull rod 2, thus providing multiple connection points with the baffle 3, which helps improve the smoothness of the baffle 3's rotation.

[0092] Furthermore, as shown in Figure 18, in this embodiment, the mounting ring 304 and the mounting shaft 202 are arranged in a one-to-one correspondence, and the mounting ring 304 is generally cylindrical with its notch facing the pull rod 2. This notch allows the mounting ring 304 to have a certain degree of elasticity, thereby facilitating its placement on the mounting shaft 202 to achieve a rotational connection between the baffle 3 and the pull rod 2.

[0093] It should be noted that by placing the notch 201 and mounting shaft 202 at the top of the tie rod 2, the baffle 3 can be partially concealed by the tie rod 2. Therefore, only the baffle 3 is visible from the outside, enhancing the overall refinement of the vehicle's interior. While it's understandable that the notch 201 and mounting shaft 202 could be placed at other locations on the tie rod 2, this would allow some of the tie rod 2 to be visible from the outside, reducing the perceived refinement of the interior. Furthermore, besides using multiple spaced mounting protrusions 303 and mounting shaft 202 to rotatably mount the baffle 3 onto the tie rod 2, a rotating shaft extending along the length of the baffle 3 can also be used, rotatably connecting it to the tie rod 2.

[0094] Furthermore, to improve the smoothness of the sliding of the pull rod 2, as shown in Figure 7, each end of the pull rod 2 is provided with a sliding rod. The sliding rod slides along the vertical direction of the vehicle and is connected to the drive mechanism. Both ends of the pull rod 2 are hinged to the corresponding sliding rods. By providing sliding rods at both ends of the pull rod 2, it is beneficial to ensure that both ends of the pull rod 2 move synchronously when unfolding or closing, avoiding problems such as skewing, jamming, or uneven rolling of the sunshade 1 caused by uneven force on one side. Furthermore, by hingedly connecting both ends of the pull rod 2 to the corresponding sliding rods, deformation of the front sunshade 1 during raising and lowering can be effectively prevented.

[0095] As a further embodiment, at least one end of the pull rod 2 is provided with a spacing adjustment part between it and the corresponding end of the slide rod. The spacing adjustment part is used to adjust the spacing between the two in the longitudinal direction of the vehicle. This arrangement allows for adjustment of the spacing between the pull rod 2 and the slide rod in the longitudinal direction of the vehicle, which is beneficial for compensating for installation and manufacturing tolerances. Specifically, for ease of explanation, in the longitudinal direction of the vehicle, the slide rod located in front of the sunshade 1 is referred to as the "front slide rod," and the slide rod located behind the sunshade 1 is referred to as the "rear slide rod."

[0096] Referring to Figures 7 and 8, to improve the smoothness of the sliding of the rear slide bar 7, a rear rail 6 extending along the vertical direction of the vehicle is provided on the door. Furthermore, to facilitate the connection between the rear slide bar 7 and the pull rod 2, as shown in Figure 8, the rear slide bar 7 includes a rear rod body 701 and a rear slider 702 located at the top of the rear rod body 701. Correspondingly, the rear end of the pull rod 2 has a rearwardly protruding rear connecting block 203, which has a connecting shaft 2031 hinged to the rear slider 702.

[0097] Correspondingly, the rear track 6 has a rear sliding groove 601 adapted to the rear rod 701, and a rear clearance groove 602 communicating with the rear sliding groove 601. The rear rod 701 is slidably disposed within the rear sliding groove 601, and the rear sliding block 702 is located within the rear clearance groove 602. Thus, the pull rod 2 can be rotated relative to the rear sliding rod 7 by the rear connecting block 203, thereby realizing the sliding of the sunshade 1.

[0098] As a further embodiment, a spacing adjustment part is provided between the rear end of the pull rod 2 and the rear slide rod 7, and includes a connecting groove 702 provided on the rear slide rod 702 along the front-rear direction of the whole vehicle. The connecting shaft 2031 is inserted into the connecting groove 702 and can rotate and move relative to the connecting groove 702 to adjust the spacing between the pull rod 2 and the rear slide rod in the front-rear direction of the whole vehicle.

[0099] Furthermore, referring to Figures 9 and 10, in order to improve the smoothness of the sliding of the front slide bar 8, a front rail 5 extending along the vertical direction of the vehicle is provided on the door. In this embodiment, the front slide bar 8 includes a front rod body 801 and a front slider 802 disposed at the top of the front rod body 801. Correspondingly, the front rail 5 has a front groove 501 adapted to the front rod body 801, and a front clearance groove 502 communicating with the front groove 501, with the front slider 802 located within the front clearance groove 502.

[0100] In this embodiment, as a further implementation, a spacing adjustment part is also provided between the rear end of the pull rod 2 and the front sliding rod 8. This spacing adjustment part includes an adjustment groove located at the front end of the pull rod 2 along its length, and a connecting rod 204 with one end slidably disposed within the adjustment groove, the other end of which is hinged to the front sliding block 802. Thus, the position between the pull rod 2 and the front pull rod 802 can be adjusted by rotating the connecting rod 204 relative to the front sliding block 802 and moving it along the adjustment groove.

[0101] The aforementioned drive mechanism includes a drive unit mounted on the vehicle door and a transmission unit located between the drive unit and the pull rod 2. As shown in Figures 19 and 20, the drive unit generally includes a drive housing mounted on the vehicle door, and a motor 12 located within the drive housing and behind the sunshade 1. The transmission unit includes a worm gear 13 mounted on the drive shaft of the motor 12, a worm wheel 14 rotatably mounted on the vehicle door, a drive gear coaxially rotating with the worm wheel 14, an intermediate gear 15 meshing with the drive gear, a transmission gear assembly meshing with the intermediate gear 15, and a transmission shaft 9 connected to the transmission gear assembly. The transmission shaft 9 is located below the sunshade 1 and extends along the length of the entire vehicle.

[0102] Specifically, as shown in Figure 20, the transmission gear assembly includes a spur gear 16 meshing with the intermediate gear 15, and a first bevel gear 17 and a first helical gear 18 coaxially arranged with the spur gear 16. Simultaneously, a second bevel gear 19 and a second helical gear 20 are respectively provided at both ends of the transmission shaft 9, and a helical section is provided at the lower end of each slide rod. The first helical gear 18 is connected to the helical section of the front slide rod 8 to drive the front slide rod 8 to rotate up and down; the first bevel gear 17 meshes with the second bevel gear 19 to drive the transmission shaft 9 to rotate; and the second helical gear 20 meshes with the helical section of the rear slide rod 7 to drive the rear slide rod 7 to rotate up and down.

[0103] The aforementioned drive mechanism is similar to the overall structure of existing car window or sunroof sunshade 1. It is not limited to the aforementioned structure, as long as it can achieve synchronous up and down sliding of the front slide bar 8 and the rear slide bar 7. The specific setting can be referred to the existing technology.

[0104] Based on the above overview, in this embodiment, when the sunshade 1 is lowered and closed, when the pull rod 2 descends to contact the upper trim panel 4, the side panels 3 tilt away from the pull rod 2, and the unfolding direction has a certain angle. When it abuts against the upper trim panel 4, it can rotate relative to the pull rod 2 due to outward force, thereby causing the side panels 3 to unfold. When unfolded, the pull cable 302 pulls the spring 11, causing the spring 11 to be under tension. Moreover, after the side panels 3 are unfolded, they cover the gap between the pull rod 2 and the upper trim panel 4, and also cover the internal structure of the upper trim panel 4, which can effectively enhance the refinement of the vehicle interior.

[0105] When the sunshade 1 is opened, the pull rod 2 rises and gradually moves away from the upper trim panel 4. The spring 11 releases its elasticity, pulls the baffles 3 on both sides inward, and moves the baffles 3 towards the closing direction of the pull rod 2 until they come into contact with the pull rod 2 and return to their final position.

[0106] Therefore, the window sunshade structure of this embodiment can both raise or roll up the sunshade 1 when it is opened or closed, and also cover the product structure inside the upper trim panel 4 when it is closed, which helps to ensure the aesthetics of the appearance and can enhance the refinement of the vehicle interior.

[0107] This embodiment also relates to a vehicle, which is equipped with the above-described window sunshade structure.

[0108] In this embodiment, the vehicle features the aforementioned window sunshade structure. Not only does the sunshade 1 provide sun protection when unfolded, but when closed, the baffle 3 abuts against and flips against the upper door trim panel 4, effectively blocking the gap between the pull rod 2 and the upper trim panel 4. This effectively conceals the structure inside the upper trim panel 4 and prevents foreign objects from entering the gap, resulting in a more aesthetically pleasing and refined interior, thus enhancing the overall vehicle quality.

[0109] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
