Technical Field

[0001] This utility model relates to the field of automotive wing door technology, and more specifically, to a wing door rotation mechanism. Background Technology

[0002] With advancements in automotive technology, car designs are constantly being updated and iterated, becoming increasingly stylish and high-end. For example, the application of wing doors. Wing doors, as a special type of door, are characterized by rotating upwards and extending outwards when opened. The hinge arm of this design typically has a rotating base as the main support and extensions on both sides as auxiliary supports. This structure makes the hinge arm prone to damage. Furthermore, the transmission mechanism that drives the rotating arm is susceptible to dust and external impurities, leading to a reduction in the lifespan of the entire hinge system.

[0013] Furthermore, the stroke of the sector gear 510 is less than the length of the sealing frame 410.

[0014] Furthermore, the sealing frame 410 and the rotating arm 300 are connected by a mounting assembly 700, which includes: a mounting plate 710 formed by a section of the outer contour of the sealing frame 410 protruding towards the rotating arm 300; a mounting groove 720 on the outer side of the rotating arm 300 that matches the mounting plate 710; and a fixing plate 730 formed by one side of the sealing frame 410 extending towards the rotating seat 200; wherein the mounting plate 710 and the rotating arm 300 are fixedly connected by screws, and the fixing plate 730 and the sector gear 510 are fixedly connected by screws.

[0015] Furthermore, the included angle between the fixing plate 730 and the mounting plate 710 is 90°.

[0016] Furthermore, the sealing frame 410 is slidably connected to the sealing cover 420 via a sliding assembly 800. The sliding assembly 800 includes: a slide bar 810 formed by protrusions on both sides of the sealing cover 420 near and away from the rotating seat 200, and a groove 820 on the sealing frame 410 that matches the slide bar 810. The sealing frame 410 is slidably disposed on the sealing cover 420 through the cooperation of the slide bar 810 and the groove 820.

[0017] Furthermore, the sealing cover 420 is also provided with a positioning piece 422, which is located on one side of the sealing cover 420 and is fixedly connected to the sealing cover 420 and one end of the slide bar 810.

[0020] Furthermore, the rotating arm 300 is provided with a plurality of countersunk holes 321, and the sector gear 510 is provided with mounting holes 320 corresponding to the positions of the countersunk holes 321, so that the sector gear 510 and the rotating arm 300 can be fixedly connected by screws.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] This utility model provides a wing door rotating mechanism. By setting a sealing assembly, the sealing frame and sealing cover of the sealing assembly form a closed area with the rotating arm. A recessed gear area for mounting bevel gears is provided inside the sealing cover, so that the sector gear and bevel gear of the transmission component are both located in this closed area, preventing dust and external impurities from entering and affecting the transmission of the bevel gear and sector gear. At the same time, the sealing cover and sealing frame are relatively slidably arranged, so that the above-mentioned sealing area forms a dynamic sealing area. As the sector gear drives the rotating arm and sealing frame to slide on the sealing cover, the position of this closed area will change, but the sector gear and bevel gear will always be within the closed area, that is, the gear area will always be located below the sealing frame. In addition, the stroke of the sector gear is less than the length of the sealing frame, thereby ensuring that the gear area will not disengage from the closed area when the sealing frame slides relative to the sealing cover, effectively preventing dust and external impurities from entering and effectively extending the service life of the transmission component.

[0023] The present invention provides a wing door rotating mechanism, which further improves the load-bearing capacity and overall strength of the outer side of the sealing frame and the sealing cover by setting several crisscrossing reinforcing ribs on the outside of the sealing frame and the sealing cover. This makes the sealing cover less prone to deformation and breakage when the sealing frame slides on the sealing cover, thereby increasing the load it can withstand and extending its service life.

[0024] This utility model provides a wing door rotating mechanism, which is a connecting component consisting of a positioning groove, a positioning column and a positioning hole. It provides a positioning method with one side and two pins when installing the sector gear and the rotating arm. This not only facilitates installation and positioning, but also greatly improves the installation accuracy of the sector gear and the rotating arm. It is also easy to process, reduces production costs, and is less prone to shaking when the sector gear drives the rotating arm to move, thus greatly enhancing stability.

[0025] This utility model provides a wing door rotating mechanism, in which a sealing frame and a rotating arm are connected by an installation component, so that both ends of the sealing frame are fixedly connected to the sector gear and the rotating arm respectively. Even if the screws at one end of the sealing frame loosen, it will not affect the fixation of the other end. At the same time, it allows the sealing frame to be better fixed to the sector gear and the rotating arm. The setting of the mounting plate and the fixing plate also has the effect of installation stability, so that the sealing frame fits against the sector gear and the rotating arm through the setting of the mounting plate and the fixing plate.

[0026] This utility model provides a wing door rotating mechanism in which the sealing frame is slidably connected to the sealing cover through a sliding component. The sliding component has a slide bar and a slide groove, which facilitates the sliding of the sealing frame on the sealing cover. At the same time, the cooperation of the slide bar and the slide groove guides the sliding of the sealing frame, making the overall movement of the rotating arm more stable.

[0027] The present invention provides a wing door rotating mechanism, and the sliding component for sliding connection between the sealing frame and the sealing cover also includes an elastic strip. Since there may be a gap between the sliding strip and the sliding groove when the sliding strip is located in the sliding groove, these gaps may cause the sealing frame to shake when sliding on the sealing cover. The elastic strip plays the role of compensating for this gap, making the overall sliding more stable and less prone to shaking.

[0028] This utility model provides a wing door rotating mechanism. By setting a positioning piece on the sealing cover, when the sealing frame and the sealing cover are slidably inserted, the sealing frame can slide into the sealing cover by aligning the sliding groove with the end of the sliding strip away from the positioning piece, or it can slide into the sealing frame by aligning the end of the sliding strip away from the positioning piece with the sliding groove of the sealing frame. After the sealing frame is inserted into the sealing cover, it will slide on the sealing cover. If it slides too much, the sealing frame will come into contact with the positioning piece, thus limiting the stroke of the sealing frame and preventing the sealing frame from separating from the sealing cover during installation. The positioning piece plays a positioning role when the sealing frame and the sealing cover are installed. Attached Figure Description

[0049] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0050] See Figures 1 to 10 This embodiment provides a wing door rotating mechanism, including: a mounting side plate 100, a rotating seat 200, a rotating arm 300, a sealing assembly 400, a transmission assembly 500, a power unit 600, a mounting assembly 700, a sliding assembly 800, and a connecting assembly 900.

[0051] The mounting side plate 100 is used to connect to the vehicle body and to provide a mounting base for the other components mentioned above.

[0052] The rotating base 200 is fixedly connected to the mounting side plate 100.

[0053] The rotating arm 300 is configured to have a rotating connection part 310, a mounting part 320 and a door connection part 330. The rotating connection part 310 is rotatably connected to the rotating seat 200, and the door connection part 330 is used to connect a scissor door.

[0054] The sealing assembly 400 includes a sealing frame 410 and a sealing cover 420. The sealing frame 410 is fixedly connected to the rotating arm 300. The sealing cover 420 covers the sealing frame 410 and is slidably connected to the sealing frame 410. The sealing cover 420, the sealing frame 410, and the rotating arm 300 together form a closed area. The sealing cover 420 is provided with a recessed gear area 421.

[0055] In this embodiment, both the sealing frame 410 and the sealing cover 420 have a number of evenly spaced reinforcing ribs 430 on their outer sides, which makes the sealing frame 410 and the sealing cover 420 stronger, increases their load-bearing capacity, and improves their service life. The reinforcing ribs 430 on the outer side of the sealing cover 420 can be arranged in a crisscross pattern, which further improves the load-bearing capacity and overall strength of the outer side of the sealing cover 420, making the sealing cover 420 less prone to deformation and breakage when the sealing frame 410 slides on the sealing cover 420.

[0056] The sliding assembly 800 is used for sliding connection between the sealing frame 410 and the sealing cover 420. The sliding assembly 800 includes: a slide bar 810 formed by protrusions on both sides of the sealing cover 420 near and away from the rotating seat 200, and a slide groove 820 on the sealing frame 410 that matches the slide bar 810; wherein the sealing frame 410 is slidably disposed on the sealing cover 420 through the cooperation of the slide bar 810 and the slide groove 820.

[0057] Since the sealing cover 420 has protruding slide bars 810 on both the side near the rotating seat 200 and the side away from the rotating seat 200, and the sealing frame 410 has a groove 820 that matches the slide bars 810, when the sealing cover 420 is connected to the sealing frame 410, the sealing frame 410 can slide into the sealing cover 420 by aligning the groove 820 with one end of the slide bar 810, or it can slide into the sealing frame 410 by aligning one end of the slide bar 810 with the groove 820, thus slidably connecting the sealing frame 410 and the sealing cover 420. By providing the slide bars 810 and the grooves 820, the sealing frame 410 is easily slidably mounted on the sealing cover 420. Simultaneously, the cooperation of the slide bars 810 and the grooves 820 guides the sliding of the sealing frame 410, making the overall movement of the rotating arm 300 more stable.

[0058] The sliding assembly 800 further includes an elastic strip 830, which is fixedly disposed at both ends of the slide bar 810 and located within the slide groove 820, abutting against the sealing frame 410. By providing the elastic strip 830, since there may be gaps between the slide bar 810 and the slide groove 820 when the slide bar 810 is located within the slide groove 820, these gaps may cause the sealing frame 410 to wobble when sliding on the sealing cover 420. The elastic strip 830 compensates for these gaps, making the overall sliding more stable and less prone to wobbling.

[0059] In this embodiment, a positioning piece 422 is also provided on the sealing cover 420. The positioning piece 422 is located on one side of the sealing cover 420 and is fixedly connected to the sealing cover 420 and one end of the slide bar 810. By providing the positioning piece 422, when the sealing frame 410 and the sealing cover 420 are slidably inserted, the sealing frame 410 can slide and insert itself by aligning the sliding groove 820 with the end of the sliding strip 810 of the sealing cover 420 away from the positioning piece 422, or by aligning the end of the sliding strip 810 of the sealing cover 420 away from the positioning piece 422 with the sliding groove 820 of the sealing frame 410. After the sealing frame 410 is inserted into the sealing cover 420, it will slide on the sealing cover 420. If it slides too much, the sealing frame 410 will come into contact with the positioning piece 422, which limits the stroke of the sealing frame 410 and prevents the sealing frame 410 from separating from the sealing cover 420 during installation. The positioning piece 422 plays a positioning role when the sealing frame 410 and the sealing cover 420 are installed.

[0060] The transmission assembly 500 includes a sector gear 510 and a bevel gear 520 that mesh with each other. The sector gear 510 is fixedly connected to the rotating arm 300 and is located within the sealing frame 410. The bevel gear 520 is rotatably mounted on the mounting side plate 100 and is located within the gear area 421.

[0061] The power unit 600 is fixedly mounted on the mounting side plate 100 and is used to drive the transmission assembly 500 to move.

[0062] The power unit 600 has two output shafts, one of which is fixedly connected to the bevel gear 520, so that the power unit 600 can drive the bevel gear 520 to rotate. After the bevel gear 520 rotates, it will drive the sector gear 510 to move by meshing with the sector gear 510, thereby causing the sector gear 510 to drive the rotating arm 300 and the sealing frame 410 to slide on the sealing cover 420.

[0063] Because a recessed gear region 421 is provided within the sealing cover 420, the bevel gear 520 can be located within the gear region 421. Simultaneously, the sector gear 510 and the bevel gear 520 are both located within the closed area formed by the rotating arm 300, the sealing frame 104, and the sealing cover 420, preventing dust and external impurities from affecting the transmission of the bevel gear 520 and the sector gear 510. As the sector gear 510 drives the rotating arm 300 and the sealing frame 410 to slide on the sealing cover 420, the position of this closed area changes, but the sector gear 510 and the bevel gear 520 remain within the closed area. That is, the gear region is always located below the sealing frame 410. The stroke of the sector gear 510 is less than the length of the sealing frame 410, thus ensuring that the gear region does not detach from the closed area when the sealing frame 410 slides relative to the sealing cover 420.

[0064] The mounting assembly 700 is used for the connection between the sealing frame 410 and the rotating arm 300. The mounting assembly 700 includes: a mounting plate 710 formed by a section of the outer ring contour of the sealing frame 410 protruding towards one side of the rotating arm 300; a mounting groove 720 on the outer side of the mounting portion 320 of the rotating arm 300 that matches the mounting plate 710; and a fixing plate 730 extending from one side of the sealing frame 410 toward the rotating seat 200. The mounting plate 710 and the mounting portion 320 of the rotating arm 300 are both provided with first threaded holes 711 for screwing in screws. The mounting plate 710 (i.e., the sealing frame 410) and the rotating arm 300 are fixedly connected by screwing in screws in the first threaded holes 711.

[0065] The fixing plate 730 and the sector gear 510 are provided with a second threaded hole 731 for screwing in a screw. The fixing plate 730 (i.e. the sealing frame 410) and the sector gear 510 are fixedly connected by screwing in a screw in the second threaded hole 731.

[0066] Because the mounting plate 710 and the mounting groove 720 are provided, and the mounting plate 710 is formed by a section of the outer ring contour of the sealing frame 410 protruding towards the rotating arm 300, after the sector gear 510 is installed with the rotating arm 300, it is necessary to fix the sealing frame 410 to the rotating arm. When fixing the sealing frame 410 to the rotating arm 300, the mounting plate 710 of the sealing frame 410 is inserted into the mounting groove 720 on the outside of the rotating arm 300. After insertion, the mounting plate 710 of the sealing frame 410 will cover the outside of the rotating arm 300, providing better protection for the sector gear 510. At the same time, after installation, the fixing plate 730 will also fit against the plane of the sector gear 510.

[0067] In this embodiment, the fixing plate 730 is configured to form a 90° angle with the mounting plate 710, which can enhance the strength and stability of the sealing frame 410, provide additional support and reinforcement, prevent deformation and damage to the sealing frame 410, and make the whole structure more stable and durable.

[0068] By setting the mounting assembly 700, both ends of the sealing frame 410 are fixedly connected to the sector gear 510 and the rotating arm 300, respectively. This design ensures that even if the screws at one end loosen, it will not affect the fixation of the other end. At the same time, it allows the sealing frame 410 to be better fixed to the sector gear 510 and the rotating arm 300. The mounting plate 710 and the fixing plate 730 also have a stable installation effect, allowing the sealing frame 410 to fit snugly against the sector gear 510 and the rotating arm 300 through the mounting plate 710 and the fixing plate 730.

[0069] The connecting assembly 900 is used for positioning and mounting the sector gear 510 and the rotating arm 300. The connecting assembly 900 includes: a positioning groove 910 opened on the rear side of the mounting portion 320 of the rotating arm 300, which matches the shape of the side of the sector gear 510 away from the gear; a positioning post 920 fixedly disposed on the side of the sector gear 510 away from the gear; and a positioning hole 930 opened on the rear side of the mounting portion 320 of the rotating arm 300, which matches the positioning post 920. The positioning hole 930 is disposed through the positioning groove 910. The side of the sector gear 510 away from the gear is disposed in the positioning groove 910.

[0070] Because the mounting portion 320 of the rotating arm 300 has a positioning groove 910 on its rear side that matches the shape of the side of the sector gear 510 away from the gear, when the sector gear 510 is installed with the rotating arm 300, the side of the sector gear 510 away from the gear can be placed in the positioning groove 910 of the rotating arm 300. The positioning groove 910 fits against the side of the sector gear 510 away from the gear, which has a stabilizing effect.

[0071] Meanwhile, when the sector gear 510 is installed with the rotating arm 300, the positioning post 920 on the side of the sector gear 510 away from the gear can be inserted into the positioning hole 930 of the rotating arm 300, thereby achieving a positioning effect.

[0072] In the above manner, after the sector gear 510 is installed into the rotating arm 300, the side of the sector gear 510 away from the gear will fit against the positioning groove 910, and the two positioning pins 920 of the sector gear 510 will be located in the positioning hole 930 of the rotating arm 300. Then, the sector gear 510 and the rotating arm 300 are fixedly connected by screws.

[0073] In this embodiment, to facilitate the fixed connection between the sector gear 510 and the rotating arm 300 via screws, the rotating arm 300 is also provided with several countersunk holes 321, and the sector gear 510 is provided with mounting holes 511 corresponding to the positions of the countersunk holes 321. By providing the countersunk holes 321 and the mounting holes 511, it is convenient to fix the sector gear 510 and the rotating arm 300 by screwing screws into the countersunk holes 321 and the mounting holes 511. The countersunk holes 321 also prevent the screw heads from protruding from the rotating arm 300, making the overall appearance more aesthetically pleasing and preventing exposed screw heads from interfering with the movement of other components.

[0074] Through the above structural design, the positioning groove 910, the positioning post 920 and the positioning hole 930 form a positioning method with one side and two pins. This not only facilitates installation and positioning, but also greatly improves the installation accuracy of the sector gear 510 and the rotating arm 300. It is also easy to process, reducing production costs. Furthermore, when the sector gear 510 drives the rotating arm 300 to move, it is not easy to shake, which greatly enhances stability.
