Description

Technical Field

[0001] The present invention relates to the field of vehicle sunroofs, and in particular to a vehicle sunroof movement device. Background Art

[0002] The car sunroof mechanism is installed on the roof of the car, which can effectively connect the air inside the car with the outside world, thereby increasing the entry of fresh air and bringing a healthy and comfortable enjoyment experience to the car owner.

[0003] A car sunroof mechanism generally includes a sunroof cover, a driving device, and a sunroof movement device that is driven by the driving device to close, lift, and open the sunroof cover.

[0004] Patent CN201320129031.8 discloses a sunroof guide linkage device, but in CN201320129031.8, the pins and sliders on the front guide device directly contact and slide with the slide grooves on the main connecting rod device, and the front guide device directly drives the main connecting rod device to complete the lifting and opening of the sunroof cover. During this process, the front weight of the sunroof cover is entirely borne by the guide device, which makes the friction resistance between the pins and sliders on the front guide device and the slide grooves on the main connecting rod device larger, so that the driving force of the driving device on the front guide device is larger, which makes the movement of the sunroof cover very rapid, and the noise generated during its movement is relatively large.

[0005] In addition, in CN201320129031.8, the sliding of the front sliding member is transmitted to the rear sliding member through the slender connecting rod. Although five small sliding members wrapped around the slender connecting rod are provided to suppress the swing or shaking of the slender connecting rod in directions outside the left and right planes to ensure the accuracy of the above-mentioned motion transmission, the rigidity of the slender connecting rod in the left and right planes is low, which makes the overall operation stability of the motion mechanism low.

[0006] In CN201320129031.8, the slide groove on the rear sliding member (such as the covering body) is in direct contact with the two positioning pins on the bracket in the rear support guide device. During the sliding process of the rear sliding member toward the rear end of the guide rail, the positioning pins slide in its slide groove and push the bracket to complete the swing. This driving method of directly applying force to the bracket to promote its swing has a larger driving force, so that the driving force applied by the driving device to the push rod device through the front guide device is larger.

[0007] Although the skylight guiding linkage device in Patent CN201320129031.8 can achieve the closing, tilting and opening of the skylight cover plate, due to the large size of the existing skylight guiding linkage device and the necessity of covering the main connecting rod device with plastic to form corresponding tracks, when manufacturing this part, the size of the injection mold is inevitably large, which will result in a high manufacturing cost.

[0008] In addition, the locking device in Patent CN201320129031.8 is a rotating latch that can rotate around the vertical axis, and all components in this locking device are made of plastic material, which will inevitably lead to poor anti-fatigue deformation ability and a high risk of fatigue failure.

[0009] Furthermore, the push rod device of the existing skylight guiding linkage device includes a slender connecting rod and several small sliding parts fixedly connected thereto, which also results in poor rigidity of the push rod device and easy deformation when sliding in the guide rail device. Further, the problems existing in the locking device and the push rod device in the existing skylight guiding linkage device of the prior art make the existing skylight guiding linkage device have certain reliability problems, and there is a high risk of failure of functions such as normal closing, tilting and opening of the skylight cover plate.

[0010] More importantly, the existing skylight guiding linkage device also does not fully consider the requirements of product modularization, serialization and generalization. When the size of the skylight cover plate changes, both the main connecting rod device and the push rod device, which are two relatively large-sized parts, need to be re-developed and designed, bringing high internal operation and management costs such as enterprise R & D, production and logistics.

Therefore, the above terms should not be construed as limiting the present invention.

[0044] Combined with the attached drawings 1 to Figure 11 , a vehicle sunroof movement device according to a preferred embodiment of the present invention will be described in detail below, where the vehicle sunroof movement device includes a guide rail assembly 10, a driving mechanism 20, a driving connecting rod 30, a main carrier 40, a linkage mechanism 50, and a rear tilting mechanism 60.

[0045] The guide rail assembly 10 includes a main guide rail 11 and at least one lifting guide rail 12. The main guide rail 11 has a front end 1101 and a rear end 1102. The main guide rail 11 forms at least one main slideway 1103 between the front end 1101 and the rear end 1102.

[0046] The lifting guide rail 12 has a lower end 1201 and a higher end 1202. The lifting guide rail 12 forms an arc-shaped guiding slideway 1203 between the lower end 1201 and the higher end 1202. The higher end 1202 of the lifting guide rail 12 is docked with the main guide rail 11, and the main slideway 1103 and the arc-shaped guiding slideway 1203 are docked to form a movement slideway.

[0047] The main guide rail 11 has a bottom wall 111 extending from the front end 1101 to the rear end 1102, a left side wall 112 extending upward from the bottom wall 111, and a right side wall 113 extending upward from the bottom wall 111 and spaced a predetermined distance from the left side wall 112, so as to form the main slideway 1103 between the left side wall 112 and the right side wall 113.

[0048] A split rail wall 114 extending respectively towards each other on the left side wall 112 and the right side wall 113 of the guide rail assembly 10 between the front end 1101 and the rear end 1102. The top of the left side wall 112 and the top of the right side wall 113 extend respectively towards each other to form a blocking wall 115, so as to form a plurality of main slideways 1103 between the blocking wall 115, the split rail wall 114, and the blocking wall 115.

[0049] Preferably, an upper slideway 1103a and a lower slideway 1103b are respectively formed from top to bottom between the blocking wall 115, the split rail wall 114, and the blocking wall 115.

[0050] More preferably, a locking port 11101 communicating with the main slideway 1103 is formed at a predetermined position on the bottom wall 111 of the guide rail assembly 10 between the front end 1101 and the rear end 1102.

[0051] The driving mechanism 20 includes a driving slider 21 and at least one transmission member 22 disposed on the driving slider 21. The transmission member 22 is configured to be drivably connected to a driving device. The driving device can be a motor. After being driven by the transmission member 22, the driving slider 21 can slide along the main slideway 1103.

[0052] The driving slider 21 has an inner side surface 201 and an outer side surface 202 opposite to the inner side surface 201. The driving slider 21 has a front end portion 211 facing the front end 1101 and a rear end portion 212 opposite to the front end portion 211.

[0053] A guide groove 213 is formed on the driving slider 21. The guide groove 213 has a straight groove portion 2131 near the rear end portion 212, a small arc portion 2132 slightly higher than the straight groove portion 2131, and a large arc portion 2133 higher than the small arc portion 2132.

[0054] A linkage pin 214 is provided on the inner side surface 201 of the driving slider 21. The linkage mechanism 50 is linkably connected to the linkage pin 214 so that when the linkage mechanism 50 and the linkage pin 214 are linked, the linkage mechanism 50 slides in the main slideway 1103.

[0055] More preferably, at least one guide foot 215 is provided on the outer side surface 202 of the driving slider 21, wherein the guide foot 215 is slidably disposed in the upper slideway 1103a and can slide back and forth in the upper slideway 1103a after being driven. The guide foot 215 can be integrally extended outward from the outer side surface 202 of the driving slider 21. The guide foot 215 can also be implemented as a plastic part wrapped around the driving slider 21. The present invention is not limited in this regard.

[0056] Preferably, noise reduction sliding feet 216 are respectively provided at the top and bottom of the driving slider 21, so that when the driving slider 21 slides in the main slideway 1103, the contact area between the driving slider 21 and the guide rail assembly 10 is reduced, thereby reducing the friction force between the driving slider 21 and the guide rail assembly 10 and reducing noise at the same time.

[0057] The driving link 30 has an outer-facing surface 301 opposite to the inner side surface 201 of the driving slider 21 and an inner-facing surface 302 opposite to the outer-facing surface 301.

[0058] The driving link 30 is provided with a guiding foot 31, wherein the guiding foot 31 protrudes from the outer-facing surface 301, and the guiding foot 31 is slidably clamped into the guiding groove 213. It is worth mentioning that the guiding foot 31 can be integrally extended outward from the outer-facing surface 301 of the driving link 30. The guiding foot 31 can also be implemented as a plastic part wrapped around the driving link 30. The present invention is not limited in this regard.

[0059] The inner-facing surface 302 of the driving link 30 is provided with a connecting member 32. Similarly, the connecting member 32 can be integrally extended outward from the inner-facing surface 302 of the driving link 30. The connecting member 32 can also be implemented as a plastic part wrapped around the driving link 30. The present invention is not limited in this regard.

[0060] The rear end of the driving link 30 is provided with a sliding foot 33, wherein the sliding foot 33 is slidably limited in the main slideway 1103, so that when the driving link 30 is driven by the driving slider 21 to slide, the sliding foot 33 is always limited in the main slideway 1103.

[0061] It is worth mentioning that the driving link 30 bears a part of the front weight of the skylight cover 900 by the sliding foot 33, rather than completely bearing the front weight of the skylight cover 900 by the guiding foot 31 only. In this way, the pressure between the guiding foot 31 and the guiding groove 213 of the driving slider 21 is reduced, thereby reducing the frictional resistance between the two, and ultimately reducing the driving force required by the driving slider 21.

[0062] The main carrier 40 includes a carrier body 41 for connecting and supporting the skylight cover 900 of the vehicle. The carrier body 41 is arranged in the same direction as the guide rail assembly 10.

[0063] The load-bearing body 41 is provided with at least one sliding foot 42 on at least one side near the front end. The sliding foot 42 extends laterally from the load-bearing body 41. Preferably, one of the sliding feet 42 is provided on each of the two sides of the load-bearing body 41. The two sliding feet 42 are respectively slidably mounted in the movement slideways.

[0064] A pair of docking holes 4101 are provided at the front part of the load-bearing body 41. The load-bearing body 41 has a first side surface 4102 disposed opposite to the inner surface 302 of the driving connecting rod 30 and a second side surface 4103 opposite to the first side surface 4102. The connecting member 32 of the driving connecting rod 30 is arranged to rotatably penetrate into the docking hole 4101 from the first side surface 4102.

[0065] Furthermore, a single-side rail 43 is provided on the second side surface 4103 of the load-bearing body 41.

[0066] It can be understood that since the docking hole 4101 on the load-bearing body 41 is connected to the connecting member 32 of the driving connecting rod 30, when the driving connecting rod 30 is driven by the driving slider 21 to slide along the main guide rail 11 from the front end 1101 to the rear end 1102, the main load-bearing frame 40 drags the skylight cover plate 900 to move in the movement slideways together.

[0067] The linkage mechanism 50 includes a locking assembly 51 and a linkage assembly 52. The locking assembly 51 includes a locking slider 511 and a pressing member 512. The locking slider 511 is connected to the pressing member 512 in a manner that it is slidably pressed against the bottom wall 111 of the guide rail assembly 10, so that after the locking slider 511 is driven, the locking slider 511 can be close to the bottom wall 111 and slide in the main slideway 1103. Specifically, in the embodiment of the present invention, the locking slider 511 can be close to the bottom wall 111 and slide in the lower slideway 1103b of the main slideway 1103.

[0068] The linkage pin 214 of the driving slider 21 is slidably connected to the locking slider 511. When the locking slider 511 is not separated from the linkage pin 214, the locking slider 511 can be driven by the linkage pin 214 of the driving slider 21 to slide in the main slideway 1103; when the locking slider 511 is separated from the linkage pin 214, the linkage between the locking slider 511 and the linkage pin 214 of the driving slider 21 is terminated.

[0069] One end of the linkage assembly 52 is connected to the locking slider 511. The locking slider 511 is installed on the main slideway 1103. Preferably, the locking slider 511 is installed on the lower slideway 1103b of the main slideway 1103.

[0070] The locking slider 511 is provided with a stop arc groove 51101. The linkage pin 214 of the drive mechanism 20 is arranged to be inserted into the stop arc groove 51101 so that when the drive slider 21 is driven to slide along the main slideway 1103, the locking slider 511 is driven by the linkage pin 214 located in the stop arc groove 51101 to slide along the main slideway 1103.

[0071] It is worth mentioning that when the skylight cover plate 900 of the vehicle is in the closed state, the guiding foot 31 on the driving connecting rod 30 is located in the straight groove part 2131 of the guiding groove 213. At the same time, the sliding foot 42 of the main carrier 40 is located at the low end 1201 of the lifting guide rail 12 and remains in the arc guiding slideway 1203. In addition, the linkage pin 214 of the drive slider 21 is inserted into the stop arc groove 51101 and is located at the front part of the stop arc groove 51101 so that when the drive slider 21 is driven by the transmission member 22 to slide along the main slideway 1103 towards the rear end 1102, the locking slider 511 can be pushed to move in linkage.

[0072] The rear lifting mechanism 60 includes a swing arm 61, a sliding driving member 62 and a sliding support member 63. The carrying body 41 of the main carrier 40 is slidably connected to the sliding support member 63.

[0073] A swing end 611 is formed at the rear part of the swing arm 61, and a connecting part 612 is formed at the middle part of the swing arm 61. The swing end 611 of the swing arm 61 is rotatably connected to the sliding support member 63. The connecting part 612 of the swing arm 61 is swingably connected to the sliding driving member 62 so that when the sliding driving member 62 is driven by the linkage assembly 52 to slide, the swing arm 61 moves along the main guide rail 11 and swings at the same time as the linkage assembly 52, and further drives the sliding support member 63 located at the swing end 611 of the swing arm 61 to slide and swing relative to the carrying body 41. When the swing end 611 of the swing arm 61 swings upward, correspondingly, the main carrier 40 supported on the sliding support member 63 drives the skylight cover plate 900 to be lifted upward together, so that the rear part of the skylight cover plate 900 is lifted.

[0074] Preferably, at least two guiding protrusions are formed in the middle of the swing arm 61, and the two guiding protrusions are located at different heights to form the connecting portion 612. An arc-shaped guiding groove 6201 is formed on the sliding driving member 62. The two guiding protrusions are respectively limited in the arc-shaped guiding groove 6201. When the sliding driving member 62 is driven by the linkage assembly 52 to move along the main guide rail 11, the swing arm 61 slides along the arc-shaped guiding groove 6201. Since the arc-shaped guiding groove 6201 is arc-shaped, and the swing end 611 and the connecting portion 621 of the swing arm 61 are correspondingly limited, therefore, while the swing arm 61 slides along the arc-shaped guiding groove 6201, it swings correspondingly. Specifically, when the sliding driving member 62 is driven by the linkage assembly 52 to move a predetermined distance along the main guide rail 11 towards the rear end 1102 of the main guide rail 11, the swing arm 61 moves towards the front part of the sliding driving member 62 along the arc-shaped guiding groove 6201, and at the same time, the swing end 611 of the swing arm 61 is lifted by a predetermined height, so that the main carrier 40 supported on the sliding support member 63 drives the sunroof cover 900 to be lifted upwards together. The sunroof cover 900 will be opened. When the sliding driving member 62 is driven by the linkage assembly 52 to move a predetermined distance along the main guide rail 11 towards the front end 1101 of the main guide rail 11, the swing arm 61 moves towards the rear end of the sliding driving member 62 along the arc-shaped guiding groove 6201, and at the same time, the swing end 611 of the swing arm 61 descends by a predetermined distance, so that the main carrier 40 supported on the sliding support member 63 drives the sunroof cover 900 to descend together. The sunroof cover 900 will be in a closed state.

[0075] Preferably, at least one limiting foot 621 is provided on the sliding driving member 62, and the limiting foot 621 is slidably limited in the main guide rail 11, so that when the sliding driving member 62 slides along the main guide rail 621, the limiting foot 621 can limit the sliding driving member 62 in the main guide rail 11 and prevent it from sliding out of the main guide rail 11.

[0076] The rear lifting mechanism 60 further includes a guiding member 64. A guiding inclined slot 6401 is formed between the front portion and the rear portion of the guiding member 64. An inner side of the front portion of the swing arm 61 is provided with a guiding foot 613. When the skylight cover plate 900 is in the closed state, the guiding foot 613 is limited in the guiding slot 6401. When the skylight cover plate 900 is switched from the closed state to the lifted state, the swing arm 61 is driven by the sliding driving member 62 to slide towards the rear end 1102 of the main guide rail 11, and swings simultaneously to drive the sliding support member 63 to lift. At the same time, the guiding foot 613 slides along the guiding inclined slot 6401 towards the rear portion of the guiding member 64. As the driving mechanism 20 continuously slides towards the rear end 1102 of the main guide rail 11, the guiding foot 613 will slide out of the guiding inclined slot 6401 from the rear portion of the guiding member 64 until the locking slider 511 falls into the locking opening 11101 on the bottom wall 111 of the main guide rail 11.

[0077] It is worth mentioning that since the guiding foot 613 at the front portion of the swing arm 61 is guided by the guiding inclined slot 6401, during the movement of the skylight cover plate 900, the swing arm 61 can only swing in a predetermined manner, so that the skylight cover plate 900 can move stably.

[0078] The guiding member 64 further forms a stepped surface 6402. Correspondingly, the swing arm 61 is provided with an auxiliary guiding foot 614. During the process of the skylight 900 being switched from the opened state to the closed state, the driving slider 21 slides towards the front end 1101 of the main guide rail 11. Correspondingly, the swing arm 61 will be driven together with the sliding driving member 62 to slide towards the front end 1101 of the main guide rail 11.

[0079] During the process of the swing arm 61 sliding towards the front end 1101 of the main guide rail 11, the swing end 611 descends, thereby driving the skylight cover plate 900 supported on the sliding support member 63 to descend. At the same time, the auxiliary guiding foot 614 will slide along the stepped surface 6402 to guide the guiding foot 613 to slide from the main slideway 1103 into the guiding inclined slot 6401. In addition, the linkage pin 214 on the driving slider 21 will also slide into the stopping arc slot 51101 of the locking slider 511.

[0080] It is worth mentioning that the linkage assembly 52 includes a linkage rod 521. The front end portion of the locking slider 511 is swingably connected to the front end portion of the linkage rod 521. The front end portion of the sliding driving member 62 is linkedly connected to the rear end portion of the linkage rod 521.

[0081] Preferably, the pressing member 512 is implemented as a pressing spring, where the pressing member 512 has a socket portion 5121 and a pressing portion 5122. The linkage rod 521 is provided with a socket platform 52101. The socket portion 5121 of the pressing member 512 is socketed on the socket platform 52101. The pressing portion 5122 is fixed to the locking slider 511. The locking slider 511 is provided with a connection hole 51102 for the pressing portion 5122 of the pressing member 512 to pass through. The pressing portion 5122 of the pressing member 512 is arranged to be able to press the locking assembly 51 of the linkage mechanism 50 against the bottom wall 111 of the guide rail assembly 10 and slide.

[0082] Preferably, the linkage assembly 52 further includes a linkage member 522. The front portion of the linkage member 522 is slidably and separably connected to the rear portion of the linkage rod 521. The rear end of the linkage member 522 is connected to the front portion of the sliding driving member 62 so that the sliding driving member 62 can be linked as the linkage member 522 slides.

[0083] Specifically, the front portion of the linkage member 522 is provided with a linkage inclined groove 52201. The rear portion of the linkage rod 521 is provided with a linkage pin body 5211. The linkage pin body 5211 is inserted into the linkage inclined groove 52201. When the linkage rod 521 is driven to slide towards the rear end 1102 of the main guide rail 11, the linkage member 522 is driven to slide together. And when the linkage member 522 is driven alone to slide towards the rear end 1102 of the main guide rail 11, the linkage pin body 5211 of the linkage rod 521 slides out of the linkage inclined groove 52201 and separates from the linkage member 522, so that the linkage member 522 alone drives the sliding driving member 62 to slide towards the rear end 1102 of the main guide rail 11. It is worth mentioning that the inner side surface 201 of the driving slider 21 of the driving mechanism 20 is provided with a guiding slideway 203. The rear lifting mechanism 60 is provided with a mating pin 65.

[0084] In one embodiment, the mating pin 65 is arranged on the linkage member 522. After the driving slider 21 slides a predetermined distance towards the rear end 1102 of the main guide rail 11, the mating pin 65 slides into the guiding slideway 203, and then the linkage member 522 can be driven by the driving slider 21 to continue sliding towards the rear end 1102 of the main guide rail 11. After the linkage member 522 is driven by the driving slider 21, the linkage pin body 5211 of the linkage rod 521 slides out of the linkage inclined groove 52201 and separates from the linkage member 522.

[0085] In another embodiment, the mating pin 65 is disposed inside the sliding driving member 62. After the driving slider 21 slides a predetermined distance toward the rear end 1102 of the main guide rail 11, the mating pin 65 slides into the guiding chute 203, enabling the sliding driving member 62 to be driven by the driving slider 21 and continue to slide toward the rear end 1102 of the main guide rail 11. Correspondingly, the linkage member 522 will also be driven by the sliding driving member 62 to separate the linkage member 522 from the linkage rod 521.

[0086] Thereby, the sunroof cover 900 can slide substantially, and further, the sliding distance of the sunroof cover 900 is greater. That is to say, at this time, the sunroof cover 900 is suitable for covering the sunroof opening of a vehicle with a larger size.

[0087] Preferably, the linkage mechanism 50 further includes a pressing member 53. The linkage member 522 is connected to the pressing member 53 in a manner that can be pressed against the main guide rail 11. Preferably, the pressing member 53 is implemented as a compression spring.

[0088] In this way, when the sunroof cover 900 needs to be switched from the open state to the closed state, the driving slider 21 will be driven by the driving slider 21 toward the front end 1101 of the main guide rail 11. Subsequently, the linkage pin body 5211 will slide into the linkage inclined groove 52201. It is worth mentioning that since the linkage member 522 is subjected to the pressure applied by the pressing member 53, when the linkage pin body 5211 slides into the linkage inclined groove 52201, the force applied by the linkage pin 5211 to the linkage member 522 is balanced, enabling the linkage pin 5211 to smoothly slide into the linkage inclined groove 52201.

[0089] It is worth mentioning that since the driving slider 21 of the driving mechanism 20 can be driven by the transmission member 22 to reciprocally slide along the main guide rail 11, the vehicle sunroof movement device 100 can drive the sunroof cover 900 to slide toward the front end 1101 of the main guide rail 11, enabling the sunroof cover 900 to be switched from the open state to the tilting state and the closed state.
