[0054] The present embodiment relates to a linkage device to overcome the technical problem that the front and rear sunshades of the side window of the rear row of a vehicle have inconsistent movement directions, resulting in a complex structure of the driving device and easy occurrence of faults.

[0055] In terms of overall structure, the linkage device of the present embodiment includes a driving part 5 arranged on the door, a first transmission part connected with the front sunshade 101, a second transmission part connected with the rear sunshade 201, and a limiting part 203. The driving part 5 is connected with the first transmission part and is used to drive the first transmission part to slide upward.

[0056] The second transmission part has an abutting part 2023 located on the upward sliding path of the first transmission part, and the first transmission part can push the abutting part 2023 when it slides upward to a preset height, and drive the second transmission part to slide upward. The limiting part 203 is located on the downward sliding path of the second transmission part, and when the first transmission part and the second transmission part are driven by the corresponding winding device to slide downward, the limiting part 203 can limit the downward displacement of the second transmission part.

[0057] The linkage device described in the embodiment can drive the first transmission part to move upward through the driving part 5, so that the front sunshade curtain 101 is opened upward, and the first transmission part pushes the abutting part 2023 when sliding to a preset height, so that the second transmission part drives the rear sunshade curtain 201 to open upward, so that the front sunshade curtain 101 and the rear sunshade curtain 201 can be opened in linkage, and during the process of moving downward and being rolled up by the front sunshade curtain 101 and the rear sunshade curtain 201, the limiting part 203 can limit the downward movement of the second transmission part, so that the rear sunshade curtain 201 is rolled up earlier than the front sunshade curtain 101, thereby realizing the linkage of the downward closing of the front sunshade curtain 101 and the rear sunshade curtain 201.

[0058] Based on the overall introduction above, the structure of the linkage device in the embodiment in the use state is shown in Figure 1 The linkage device is arranged on the rear door, and is used for shading the main window and the triangular window of the rear side window. The front roller box 1 for rolling up the front sunshade curtain 101 is arranged in the door and below the main window. The rear roller box 2 for rolling up the rear sunshade curtain 201 is arranged in the door and below the triangular window. The shafts in the front roller box 1 and the rear roller box 2 can be rolled up by the corresponding rolling devices. The front sunshade curtain 101 in the unfolded state is matched with the shape and specification of the main side window, and the rear sunshade curtain 201 in the unfolded state is matched with the shape and specification of the triangular window. The specific structure of the rolling device can refer to the prior art, and will not be described in detail here.

[0059] As a preferred embodiment, the first transmission part in the embodiment includes a slide 6 arranged on the door along the height direction of the whole vehicle, and a sliding block slidingly arranged on the slide 6. The front sunshade curtain 101 is provided with a front pull rod 102 arranged along the upper edge thereof, and the front pull rod 102 is hingedly connected with the sliding block. The driving part 5 is used for driving the sliding block to slide on the slide 6, and pushing the abutting part 2023 through the sliding block.

[0060] The shape of the front pull rod 102 is matched with the shape of the upper edge of the main window. Here, the slide 6 and the sliding block are arranged, which is beneficial to improve the stability of the front sunshade curtain 101 in the process of opening and closing upward and downward. The front pull rod 102 can rotate freely with the movement of the sliding block, which not only can effectively avoid the deformation of the front sunshade curtain 101 in the lifting process due to uneven force, but also is beneficial to enhance the shading effect. The sliding of the sliding block in the slide 6 and the hinged connection of the front pull rod 102 with the sliding block are beneficial to improve the effect of the front sunshade curtain 101 in the process of unfolding or folding, and prolong the service life of the linkage device.

[0061] As a feasible embodiment, as shown in Figure 1 and Figure 3As shown in the drawings, the slide 6 in the embodiment is provided in two parts on the front and rear sides of the front sunshade curtain 101, and the slide block is arranged on each slide 6. The two ends of the front pull rod 102 are hingedly connected to the corresponding slide blocks. At least one end of the front pull rod 102 is provided with a spacing adjustment part between the corresponding end of the slide block, which is used to adjust the spacing between the two in the front-rear direction of the vehicle.

[0062] In the embodiment, the two slides 6 are provided in two parts on the front and rear sides of the front sunshade curtain 101, and the slide blocks are arranged on each slide 6. The two ends of the front pull rod 102 are hingedly connected to the corresponding slide blocks. At least one end of the front pull rod 102 is provided with a spacing adjustment part between the corresponding end of the slide block, which is used to adjust the spacing between the two in the front-rear direction of the vehicle.

[0063] In the embodiment, the two slides 6 are arranged in the doors on the front and rear sides of the main window, and the slides 6 are arc-shaped to match the shape of the door. The slide 6 arranged at the front is higher than the slide 6 arranged at the rear. The structure of the two slides 6 can be referred to as shown in Figure 4 and Figure 5 In the embodiment, the two ends of the front pull rod 102 are hingedly connected to the corresponding slide blocks, which is also conducive to ensuring the flexibility of the front pull rod 102 in the up-down movement, thereby ensuring the unfolding or folding of the front sunshade curtain 101 and the rear sunshade curtain 201.

[0064] In the specific arrangement, the slide 6 can be arranged close to the side of the glass slide rail facing the vehicle interior, and the bottom of the slide 6 can be mounted on the front roller shutter box 1 and fixed on the glass slide rail of the door. As shown in Figure 4 and Figure 5 The cross section of the slide 6 can be circular, and one side of the slide 6 has an opening extending in the length direction of the slide 6.

[0065] For the description of the slide blocks below, the slide block connected to the front end of the front pull rod 102 is referred to as the front slide block 3, and the slide block connected to the rear end of the front pull rod 102 is referred to as the rear slide block 4. The front slide block 3 and the rear slide block 4 each have a main body part 301 and a sliding part 302 arranged on the main body part 301. The sliding part 302 is slidably arranged in the corresponding slide 6, and the main body part 301 is located outside the slide 6. In the embodiment, the cross section of the slide 6 is circular, and the cross section of the sliding part 302 is also circular, so that the outer circumferential surface of the sliding part 302 can abut against the inner circumferential wall of the slide 6, which is conducive to the arrangement of the slide blocks in the slide 6 and also conducive to improving the stability of the slide blocks in the sliding movement.

[0066] As an exemplary structure of the interval adjusting part, the interval adjusting part of the embodiment comprises an adjusting rod 1025, one end of the adjusting rod 1025 is slidingly arranged on the front pull rod 102 along the front-rear direction of the vehicle, and the front pull rod 102 is connected to the sliding block through the adjusting rod 1025. In this way, the adjusting rod 1025 not only bears the function of interval adjustment, but also enhances the stability of the connection between the front pull rod 102 and the sliding block.

[0067] Specifically, as shown in Figures 6 to 8 , the adjusting rod 1025 is arranged at the front end of the front pull rod 102. In order to facilitate the arrangement of the adjusting rod 1025, a sliding groove extending along the front-rear direction of the vehicle is arranged at the front end of the front pull rod 102, the rear end of the adjusting rod 1025 is slidingly arranged in the sliding groove, and the front end of the adjusting rod 1025 is connected to the main body part 301 of the front sliding block 3 through a hinge shaft 1024. With the up-down sliding of the front pull rod 102, the length of the adjusting rod 1025 in the sliding groove can be adaptively adjusted according to the interval between the two sliding tracks 6 in the front-rear direction of the vehicle. For example, when the interval between the two sliding tracks 6 becomes larger, the adjusting rod 1025 slides forward, and the length of the adjusting rod 1025 in the sliding groove becomes shorter to meet the sliding requirement of the front pull rod 102. When the interval between the two sliding tracks 6 becomes smaller, the adjusting rod 1025 slides backward, and the length of the adjusting rod 1025 in the sliding groove becomes longer.

[0068] As another exemplary structure of the interval adjusting part, the interval adjusting part comprises an adjusting hole 401 arranged on the sliding block along the front-rear direction of the vehicle, and the hinge shaft 1024 between the front pull rod 102 and the sliding block is inserted into the adjusting hole 401. In this way, while ensuring the interval adjustment, the stability of the connection between the front pull rod 102 and the sliding block is also enhanced.

[0069] Specifically, as shown in Figure 6 , Figure 9 and Figure 10 , an installation groove extending along the front-rear direction of the vehicle is arranged on the main body part 301 of the rear sliding block 4, the adjusting hole 401 is arranged on the two side walls of the installation groove, the rear end of the front pull rod 102 is inserted into the installation groove, and the hinge shaft 1024 at the rear end of the front pull rod 102 is arranged through the adjusting hole 401 on the corresponding side. With the up-down sliding of the front pull rod 102, the position of the hinge shaft 1024 in the adjusting hole 401 can be adjusted according to the interval between the two sliding tracks 6 in the front-rear direction of the vehicle. For example, when the interval between the two sliding tracks 6 becomes larger, the hinge shaft 1024 slides forward in the adjusting hole 401 to meet the sliding requirement of the front pull rod 102. When the interval between the two sliding tracks 6 becomes smaller, the hinge shaft 1024 slides backward in the adjusting hole 401.

[0070] In specific implementation, in addition to the above-mentioned scheme that the adjusting rod 1025 is arranged at the front end of the front pull rod 102 and the adjusting hole 401 is arranged on the rear sliding block 4, the adjusting rod 1025 can also be arranged at both ends of the front pull rod 102, or the adjusting hole 401 can be arranged on the front sliding block 3 and the rear sliding block 4 respectively, as long as the use requirement is met.

[0071] As a preferred embodiment, the first transmission part in the embodiment further comprises a sliding rod 7 slidingly arranged in the sliding channel 6 and a transmission shaft 8 rotatably arranged below the front sunshade curtain 101. The top of the sliding rod 7 is connected with the corresponding sliding block, and the bottom is connected with the transmission shaft 8 in transmission. The driving part 5 is used to drive the transmission shaft 8 to rotate and drive the sliding block to slide through the sliding rod 7. Due to the cooperation of the sliding rod 7 and the transmission shaft 8, when the transmission shaft 8 below the front sunshade curtain 101 rotates, the sliding rod 7 uniformly drives the sliding block to rise or fall, so that the front sunshade curtain 101 is more uniform in force during lifting.

[0072] Specifically, as shown in Figure 2 , the sliding rod 7 is arranged in each sliding channel 6. Considering that the sliding channel 6 is arc-shaped, the sliding rod 7 here should have support effect while being flexible. The top end of each sliding rod 7 is connected with the sliding part 302, so that the sliding rod 7 can drive the front sliding block 3 and the rear sliding block 4 to slide up and down synchronously during the up-and-down sliding process.

[0073] To drive each sliding rod 7 to slide up and down, in the embodiment, as shown in Figure 12 , the bottom of the sliding channel 6 is rotatably provided with a mounting sleeve 601, and the sliding rod 7 is rotatably connected with the mounting sleeve 601 through a part of the helical segment 701 arranged on the sliding rod 7. The transmission shaft 8 is connected with the helical segment 701 in engagement through the transmission teeth 801 arranged on the transmission shaft 8, so as to drive the sliding rod 7 to move up and down. Here, the mounting sleeve 601 is arranged at the bottom of the sliding channel 6 arranged in front, and is rotatably connected with the part of the helical segment 701 on the sliding rod 7 through the mounting sleeve 601, while the transmission shaft 8 is engaged with the helical segment 701 through the transmission teeth 801 on the transmission shaft 8, which is beneficial to realize the efficient conversion from the circumferential rotation of the transmission shaft 8 to the linear up-and-down movement of the sliding rod 7, so that the lifting response of the front sunshade curtain 101 is more rapid and accurate.

[0074] Specifically, to prevent the mounting sleeve 601 from sliding in the up-and-down direction of the sliding channel 6, a flange 6011 protruding radially outward is arranged at the top end of the mounting sleeve 601, and a limiting groove is arranged on the sliding channel 6 for the flange 6011 to be inserted. By inserting the flange 6011 into the corresponding limiting groove, the mounting sleeve 601 can be rotatably arranged in the sliding channel 6. When the sliding rod 7 is driven to slide up and down, the mounting sleeve 601 can be rotated by the helical segment 701.

[0075] In addition, in some embodiments, the transmission shaft 8 is provided with a transmission gear 801, and the bottom of the slide 6 is rotatably provided with a connecting gear 602. The transmission gear 801 is connected to the spiral segment 701 through the connecting gear 602, and can drive the slide rod 7 to move up and down. Specifically, as shown in Figure 13 the bottom of the slide 6 is rotatably provided with a connecting gear 602, and the connecting gear 602 has a first tooth portion 6021 connected to the spiral segment 701, and a second tooth portion 6012 connected to the transmission gear 801.

[0076] The second tooth portion 6012 and the transmission gear 801 are conical gears. The transmission gear 801 on the transmission shaft 8 drives the connecting gear 602 to rotate through the second tooth portion 6012, and the first tooth portion 6021 on the connecting gear 602 drives the spiral segment 701 to move up and down, thereby driving the slide rod 7 to slide upward. It can be understood that in some embodiments, the front and rear slides 6 can be provided with mounting sleeves 601 or connecting gears 602, as long as the use requirements are met.

[0077] The driving part 5 in the embodiment can adopt an existing motor. Figure 11 As shown in the figure, the power output end of the motor is provided with a worm 501 arranged along the axial direction of the transmission shaft 8. An output gear 502 connected to the worm 501 is arranged above the worm 501. By driving the worm 501 to rotate, the output gear 502 can be driven to rotate. A first conical gear 5021 is arranged on the side of the output gear 502, and a second conical gear 802 is arranged on the transmission shaft 8 and connected to the first conical gear 5021. The second conical gear 802 acts as a steering gear. When the output gear 502 rotates, the transmission shaft 8 can be driven to rotate through the meshing of the first conical gear 5021 and the second conical gear 802. At this time, the transmission shaft 8 can drive the slide rod 7 to slide up and down through the spiral segment 701 and the transmission gear 801.

[0078] It should be noted that in addition to the slide rod 7, the power of the driving part 5 can also be transmitted to the front slide block 3 and the rear slide block 4 by other structures. For example, a pull wire or other structure that can drive the slide block to slide up and down can be arranged between the two ends of the transmission shaft 8 and the slide block. Taking the pull wire as an example, a pulley is arranged on the top of the slide 6 above the highest position of the slide block. The pull wire is connected to the corresponding slide block after winding around the pulley. The slide block can be driven to slide up and down by winding and unwinding the pull wire at both ends of the transmission shaft 8.

[0079] In a preferred embodiment, the abutment portion 2023 is also provided with a slider that is slidably mounted on the rear slide rail 6. To distinguish it from the slider connected to the front pull rod 102, the slider on the abutment portion 2023 is referred to as the upper slider 2024. The upper slider 2024 and the rear slider 4 are slidably mounted on the same slide rail 6, and the upper slider 2024 is located above the rear slider 4. Specifically, the rear slider 4 pushes the upper slider 2024, thereby causing the rear sunshade 201 to move upward and unfold. In this embodiment, the rear slider 4 and the upper slider 2024 are slidably mounted on the same slide rail 6, which simplifies the linkage mechanism, reduces the space occupied by the slider on the window, and makes the linkage mechanism more compact and refined.

[0080] In this embodiment, the rear slider 4 pushes the upper slider 2024 upwards. This physical pushing method of the abutting part 2023 of the second transmission unit eliminates the need for electronic control signals and directly transmits power through mechanical limits, avoiding asynchronous actions caused by circuit delays or malfunctions. At the same time, this physical pushing method also helps reduce the complexity of the vehicle's electrical system, thereby improving the reliability of the linkage device during use.

[0081] like Figure 1 and Figure 14 As shown, the upper edge of the rear sunshade 201 is provided with a rear pull rod 202. The rear pull rod 202 has a horizontal portion 2021 connected to the rear sunshade 201, and a vertical portion 2022 connected to the horizontal portion 2021 and extending upward. An abutment portion 2023 is provided on the vertical portion 2022 and extends from rear to front along the front-rear direction of the vehicle. This structural arrangement of the rear pull rod 202 not only facilitates the connection with the rear sunshade 201 but also the placement of the abutment portion 2023, thereby improving the unfolding or retracting effect of the rear sunshade 201. In this embodiment, the limiting portion 203 includes a limiting protrusion provided on the rear roller shutter box 2. This limiting protrusion has the advantages of simple structure, easy arrangement, and good limiting effect.

[0082] In this embodiment, by changing the height of the limiting protrusion, the drawback of the front sunshade 101 and the rear sunshade 201 being unable to open and close synchronously due to inconsistent heights can be avoided, thereby enabling the application of different window shapes on different vehicle models.

[0083] For the connection between the front sunshade curtain 101 and the front pull rod 102, and the connection between the rear sunshade curtain 201 and the rear pull rod 202. The front pull rod 102 and the rear pull rod 202 in the embodiment each include an internally threaded portion 1021 and an externally threaded portion 1022 connected by screwing, and the upper edge of the sunshade curtain is clamped between the internally threaded portion 1021 and the externally threaded portion 1022, and after welding of the internally threaded portion 1021 and the externally threaded portion 1022, the internally threaded portion 1021, the externally threaded portion 1022 and the sunshade curtain located therebetween are fixedly connected together. In addition, in order to further improve the installation convenience of the linkage device, the rear end of the front roller shutter box 1 and the front end of the rear roller shutter box 2 are connected together.

[0084] In use of the linkage device in the embodiment, after the driving part 5 is started, the second bevel gear 802 can drive the transmission shaft 8 to rotate, the transmission teeth 801 at the front end of the transmission shaft 8 are directly connected with the spiral segment 701, and the slide rod 7 is driven to slide upward, the transmission teeth 801 at the rear end of the transmission shaft 8 are connected with the spiral segment 701 through the connecting teeth 602, and the slide rail is driven to slide upward. At this time, the front pull rod 102 moves upward, and in turn drives the front sunshade curtain 101 to unfold first.

[0085] When the rear slide block 4 slides upward to abut against the upper slide block 2024, the abutting portion 2023 can be pushed upward, and in turn the rear pull rod 202 drives the rear sunshade curtain 201 to unfold upward until the front sunshade curtain 101 and the rear sunshade curtain 201 are unfolded to the use state.

[0086] When it is needed to roll up the sunshade curtain, the driving part 5 is first made to idle, at this time, only through the winding device in each roller shutter box, the front pull rod 102 and the rear pull rod 202 can drive the corresponding slide block and the slide rod 7 to slide downward, at this time, the front sunshade curtain 101 and the rear sunshade curtain 201 can be respectively wound in the front roller shutter box 1 and the rear roller shutter box 2. When the rear pull rod 202 abuts against the limiting protrusion, it indicates that the rear sunshade curtain 201 is wound in place, at this time, the front sunshade curtain 101 continues to be wound until winding is completed.

[0087] The linkage device described in the embodiment can realize synchronous linkage opening and closing of the front sunshade curtain 101 and the rear sunshade curtain 201 with different heights through optimization of the structure of the linkage device and cooperation of the first transmission part and the second transmission part, which is beneficial to improve the convenience and technological sense of use of the sunshade curtain. In addition, the structure of the entire linkage device is simple, easy to arrange and implement, and the stability and reliability of the entire linkage device are higher, and the linkage device is not prone to failure in use, thereby prolonging the service life of the linkage device.
