[0001] This invention relates to the field of automobile doors, specifically to a dual-rotation-axis hinge assembly and an automobile body assembly using the hinge assembly. Background Technology
[0002] Automobiles are a common means of transportation in people's lives today, playing an irreplaceable role in the development of modern society.
[0003] Looking ahead to the 21st century, as the electrification, intelligentization, connectivity, and sharing of automobiles move from "concept" to practical application, people's needs for cars are no longer limited to transportation tools. Instead, they encompass various aspects of travel-related needs, such as navigation, consumption, entertainment, and interaction, making cars another "intelligent center" in life.
[0004] This has led to higher demands for the convenience and comfort of cars. In the field of car doors, all sorts of ingenious ideas have sprung up like mushrooms after rain, such as double doors, scissor doors, falcon wing doors, and sliding doors.

[0042] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and the description of the preferred embodiments.
[0043] A dual-rotation-axis hinge assembly includes an adjustment mechanism, a connecting mechanism, and a driving mechanism. The hinge assembly 1 disclosed in this invention can realize the automatic opening and closing of the car door 9 through the coordinated use of the adjustment mechanism, the connecting mechanism, and the driving mechanism.
[0044] The dual-rotation-axis hinge assembly 1 disclosed in this invention is mainly used for the connection between the door 9 and the body 10. It mainly includes an adjustment mechanism, a connecting mechanism, and a driving mechanism. The adjustment mechanism is set to facilitate the control of the relative movement of the connecting mechanism under the drive of the driving mechanism, thereby realizing the opening and closing of the door 9. The connecting mechanism is mainly used for the connection between the adjustment mechanism and the body 10 and the door 9. The driving mechanism is used to control the relative movement of the components connected to both ends of the hinge assembly 1.
[0045] Specifically, the adjustment mechanism of the present invention includes an adjustment block 2; in the present invention, the adjustment block 2 plays a good bridging role, facilitating the connection between the body connection part and the door connection part; in addition, the connection mechanism of the present invention includes a body connection part and a door connection part; the present invention facilitates the connection between the adjustment block 2 and the door 9 or the body 10 by setting the body connection part and the door connection part.
[0046] Furthermore, in this invention, the vehicle body connecting part includes a vehicle body block 4, and the door connecting part includes a door block 3. This invention facilitates the connection between the adjusting block and the door 9 or the vehicle body 10 through the connection between the vehicle body block 4 and the door block 3. Additionally, in this invention, the adjusting block 2 is rotatably connected to both the vehicle body block 4 and the door block 3. This rotatable connection can be achieved through a pivot shaft (described below) or through a hinge, pin, or other rotating mechanism. The purpose is to achieve the connection and relative rotation between the adjusting block 2 and the vehicle body block 4 and the door block 3, thereby reducing interference issues.
[0047] In addition, the drive mechanism described in this invention includes a drive unit connected to the adjustment block 2; the drive unit is mainly used to control the position of the adjustment block, thereby driving the body block 4 and the door block 3 to move, and finally driving the door 9 to rotate, thereby realizing the opening and closing of the door 9.
[0048] Furthermore, in this invention, the driving unit includes an electric support rod 7; one end of the electric support rod 7 is connected to the adjusting block 2, and the other end is connected to the vehicle body 10; both ends of the electric support rod 7 are hinged to the adjusting block 2 and the vehicle body 10 respectively; the electric support rod 7 extends and shortens its own length to pull the door 9, thereby realizing the opening and closing of the door 9.
[0049] Furthermore, in this invention, the adjustment block 2 is connected to the body block 4 via a first rotating shaft 6, and the adjustment block 2 is connected to the door block 3 via a second rotating shaft 5. In a specific implementation, the first rotating shaft 6 passes through both the adjustment block and the body block 4, and the second rotating shaft 5 passes through both the adjustment block 2 and the door block 3. Based on the above configuration, the connection and assembly of the adjustment block 2, the body block 4, and the door block 3 are facilitated.
[0050] Furthermore, the hinge assembly 1 in this invention also includes a limiting part disposed on the door 9, the limiting part including an electric limiter 8 disposed on the door 9; the electric limiter 8 of this invention mainly works in conjunction with the controller 1-1 to control the opening degree of the door 9.
[0051] Furthermore, in this invention, the body block 4 includes a base plate 41 connected to the body 10. The base plate 41 is a flat plate structure with a fixing through hole. During actual installation, the body block 4 is installed on the body 10 by bolts passing through the fixing through hole. At the same time, a limiting block 42 is provided on the base plate 41. The limiting block 42 plays a good bridging role, mainly facilitating subsequent connection with the adjusting block 2. The limiting block 42 is equivalent to a protrusion, arranged in the middle area of the base plate 41, and is protruding, which facilitates the subsequent connection of the first rotating shaft 6. This achieves the connection between the limiting block 42 and the adjusting block 2. In addition, in this invention, the limiting block 42 is arranged at an angle, and the horizontal projection of the limiting block 42 coincides with the adjusting block 2. This setting allows the limiting block 42 to act as a limiting component during actual use, preventing the adjusting block from over-rotating and thus preventing the door 9 from over-opening.
[0052] Furthermore, in this invention, the adjusting block 2 includes an adjusting block body, which includes a block 22. The block 22 is connected to the limiting block 42 on the body block 4 via a connecting block 21. The block 22 is the main connecting structure of the adjusting block 2. In addition, the block 22 is provided with a connecting block 21, which plays a good bridging role and facilitates the connection between the adjusting block 2 and the body block 4. In actual arrangement, each block 22 is provided with two connecting blocks 21, which are spaced apart and form an assembly gap between them. During subsequent connection, the adjusting block 2 is distributed on both sides of the limiting block 42 through the assembly gap. This arrangement enables the adjusting block 2 and the body block 4 to have relative limiting ability during subsequent use, preventing axial movement between the adjusting block 2 and the body block 4.
[0053] In addition, the block 22 described in this invention is an arc-shaped plate; the arc-shaped block 22 structure of this invention makes the adjusting block 2 have a certain avoidance function, which facilitates the subsequent arrangement of the door block 3, and at the same time facilitates the flipping operation of the adjusting block 2.
[0054] Furthermore, in this invention, the door block 3 includes a connecting plate 31, which is connected to the block 22 via a bridging block 32. In this invention, the connecting plate 31 plays a good bridging role, facilitating the connection between the door block 3 and the door 9. In addition, the bridging block 32 plays a good bridging role, facilitating the connection between the connecting plate 31 and the adjusting block 2. In actual connection, two bridging blocks 32 are also provided, which are spaced apart to form a groove. In actual installation, the connecting plate 31 is connected to both sides of the adjusting block via the two bridging blocks 32. The two bridging blocks 32 also play a lateral limiting role, preventing the door block 3 and the adjusting block from moving along the second rotating shaft 5 axially.
[0055] Furthermore, the adjustment block body described in this invention is provided with a mounting groove 43. The mounting groove 43 has two functions: firstly, it effectively reduces weight and decreases the number of adjustment blocks 2; secondly, it facilitates the connection with the drive unit and prevents the connection between the drive unit and the adjustment block 2 from protruding from the adjustment block 2. Additionally, the body block 4 described in this invention is provided with a material reduction groove 23. The material reduction groove 23 extends from the base plate 41 into the limiting block 42. The material reduction groove 23 effectively reduces weight, thereby reducing the weight of the body block 4 and contributing to a reduction in the weight of the dual rotating shaft hinge assembly 1.
[0056] A car body assembly 10 includes a body 10 and a door 9 mounted on the body 10. The door 9 is connected to the body 10 via a double-rotating-axis hinge assembly 1. This invention facilitates the connection between the door 9 and the body 10 through the hinge assembly 1. Furthermore, by using an adjustment mechanism, a connecting mechanism, and a drive mechanism in conjunction, this invention enables automatic opening and closing of the door 9. When the hinge assembly 1 disclosed in this invention is applied to the entire vehicle, in conjunction with the slide rail mechanism 9-1, it allows the door 9 to have a larger opening space, solving the problem of interference from the opening motion envelope of the door 9 due to its strong side concavity and convexity. It also addresses the space requirements for arranging the rear door hinge at the rear of the door 9 in open-door models, increasing the freedom of hinge arrangement, minimizing the impact on the styling surface, and eliminating the need for significant adjustments to the sheet metal and C-pillar. Moreover, it enables automated control, eliminating the need for manual opening and closing, making it more intelligent and convenient. Furthermore, when the door is closed, the slider 91 is fixed relatively to the left and right within the slide rail 101, eliminating the risk of the door being blown open due to lock failure, thus enhancing safety.
[0057] Furthermore, in this invention, a slide rail mechanism 9-1 is provided between the car door 9 and the vehicle body 10. The slide rail mechanism 9-1 includes a slider 91 disposed on the car door 9 and a slide rail 101 disposed on the vehicle body 10. The slider 91 is sleeved on the slide rail 101. In this invention, the slide rail mechanism 9-1 can limit the relative movement between the car door 9 and the vehicle body 10, making it convenient for the car door 9 to move relative to the vehicle body 10 and for the subsequent opening of the car door 9. In addition, in actual arrangement, in order to avoid interference between the relative movement of the car door 9 relative to the vehicle body 10 and the rotation of the car door 9, the slide rail 101 is required to be arranged intersecting with the X direction of the car in this invention. This design allows the car door 9 to move outward and backward or inward and forward simultaneously when it is opened or closed, making it convenient to open and close the car door 9.
[0058] In addition, the slide rail 101 mentioned above is arranged to intersect with the X direction of the vehicle; the angle of this intersection is designed according to the needs, but it is required that the arrangement of the slide rail and the slider should not affect the opening and closing of the door.
[0059] A double-door vehicle body assembly 10 includes a vehicle body 10, on which doors 9 are provided; the doors 9 are arranged in a double-opening manner on the vehicle body 10; each door 9 is connected to the vehicle body 10 via a double-rotating-axis hinge assembly 1; a slide rail mechanism 9-1 is provided between the door 9 and the vehicle body 10, the slide rail mechanism 9-1 including a slider 91 disposed on the door 9 and a slide rail 101 disposed on the vehicle body 10; the slider 91 is sleeved on the slide rail 101; the slide rail 101 is arranged intersecting the vehicle's X-direction; the double-rotating-axis hinge assembly 1 disclosed in this invention is mainly used in vehicles with double-door 9, and the double-rotating-axis hinge assembly 1 disclosed in this invention can achieve a larger opening degree for the doors 9 in vehicles with double-door 9, changing the problem of the small opening degree of the doors 9 in traditional side-opening vehicle models.
[0060] In this invention, by setting up a sliding rail mechanism, the distance between the door and the vehicle body can be increased when the door is opened, so that the door can open to a greater degree and reduce interference when the door is opened.
[0061] In addition, to avoid interference, in the process of opening and closing the car door in this invention, the slider and the slide rail are in a disengaged and engaged state. When in the engaged state, the slider is on the slide rail, and the two cooperate with each other to play a good guiding and limiting role. When in the disengaged state, the electric support rod continuously pushes or pulls the car door, causing the slider to disengage from the slide rail, thereby realizing the rotation operation of the car door.
[0062] Therefore, in order to facilitate the separation and cooperation of the two, the two ends of the slide rail are required to be arc-shaped. This setting plays a good guiding role and facilitates the cooperation between the slider and the slide rail.
[0063] specific:
[0064] This invention discloses a dual-rotation-axis hinge assembly 1, mainly comprising an adjustment mechanism, a connecting mechanism, and a driving mechanism. The adjustment mechanism includes an adjustment block 2. The connecting mechanism includes a body connecting part and a door connecting part. The body connecting part includes a body block 4, and the door connecting part includes a door block 3. The adjustment block 2 is rotatably connected to both the body block 4 and the door block 3. The driving mechanism includes a driving part connected to the adjustment block 2. The driving part includes an electric support rod 7. One end of the electric support rod 7 is connected to the adjustment block 2, and the other end is connected to the body 10. Both ends of the electric support rod 7 are hinged to the adjustment block 2 and the body 10, respectively. The adjustment block 2 is connected to the body block 4 via a first rotating shaft 6, and the adjustment block 2 is connected to the door block 3 via a second rotating shaft 5.
[0065] In practical use, the body block 4 is installed on the body 10, the door block 3 is installed on the door 9, the adjusting block 2 connects the body block 4 (connecting shaft is the first rotating shaft 6) and the door block 3 (connecting shaft is the second rotating shaft 5), one end of the electric support rod is fixed on the body 10 and the other end is fixed on the adjusting block 2, the guide rail is fixed on the body 10, the slider 91 is fixed on the door 9, and the controller 1-1 is installed on the door 9.
[0066] Working principle: When controller 1-1 receives the door opening signal, it outputs a low level, the electric strut is connected, and the electric strut extends. The double rotating shaft hinge assembly 1 disclosed in this invention rotates from position 1 to position 2. The door is subjected to an outward and backward force, and the slider 91 moves along the slide rail 101 to position 2 and stops. When controller 1-1 receives the signal that the connecting rod has reached the position, it outputs a low level to the electric limit switch 8, the electric limit switch 8 is connected, and the electric limit switch 8 rotates to position 3 and stops, completing the door opening. Closing the door is the reverse.
[0067] Through the above design, the present invention enables vehicles with double doors to have a larger opening space, solves the problem of interference in the opening motion envelope of the door 9 with strong side concavity and convexity, solves the space requirement for the rear door hinge of the double door model to be arranged at the rear end of the door 9, improves the freedom of hinge arrangement, has less impact on the styling surface and does not require a lot of avoidance on the sheet metal and C-pillar.
[0068] Furthermore, it can be automatically controlled, eliminating the need for manual opening and closing, making it more intelligent and convenient. Moreover, when the door is closed, the slider 91 is fixed in the slide rail 101, with the sliders on both sides relatively fixed, eliminating the risk of the door being blown open due to lock failure, thus enhancing safety.
[0069] Obviously, the specific implementation of this invention is not limited to the above-described methods. Any non-substantial improvements made using the inventive concept and technical solution of this invention are within the protection scope of this invention.
