To this end, this application proposes a hinge assembly for a scissor door, which enables the door to open in a combined manner to the side and upward.

[0048] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0049] The following is for reference. Figures 1-14 A hinge assembly 100 for a scissor door according to an embodiment of the first aspect of this application is described.

[0050] like Figure 1 As shown, the hinge assembly 100 of the scissor door according to the first aspect embodiment of this application includes: a mounting base 10, a connecting base 20, a first rotating member 30, a second rotating member 40, a first hinge arm 50, and a second hinge arm 60.

[0051] Specifically, the mounting base 10 is used to connect to the body 200 of the vehicle 1000. The mounting base 10 is provided with a first mounting portion 11 and a second mounting portion 12; the first mounting portion 11 and the second mounting portion 12 are arranged at intervals. For example... Figure 1 As shown, the mounting base 10 extends vertically, and the first mounting part 11 and the second mounting part 12 are disposed vertically on the mounting base 10, with the second mounting part 12 located below the first mounting part 11.

[0052] like Figure 1 As shown, the connecting seat 20 is used to connect with the door 300. The connecting seat 20 is provided with a first connecting portion 2211 and a second connecting portion 2231; the first connecting portion 2211 and the second connecting portion 2231 are arranged at intervals. For example, Figure 1 As shown, the connector 20 is vertically arranged, and the first connecting part 2211 and the second connecting part 2231 are arranged vertically on the connector 20 at intervals, with the second connecting part 2231 located below the first connecting part 2211.

[0053] like Figure 1 As shown, the first rotating member 30 is rotatably connected to the first mounting portion 11, and the first rotating member 30 is provided with a first hinge portion 32. For example, the first rotating member 30 is provided on the first mounting portion 11, and the first rotating member 30 can rotate left and right about the vertical axis relative to the first mounting portion 11.

[0054] like Figure 1 As shown, the second rotating member 40 is rotatably connected to the second mounting part 12, and the second rotating member 40 is provided with a second hinge part 421. For example, the second rotating member 40 is provided on the second mounting part 12 and can rotate up and down around the front-to-back axis. When the second rotating member 40 rotates from bottom to top, it can not only open the door 300 upward, but also open the door 300 outward.

[0055] The first hinge arm 50 has a first end 51 and a second end 52. The first end 51 is rotatably connected to the first hinge portion 32, and the second end 52 is rotatably connected to the first connecting portion 2211. That is, the first hinge arm 50 is connected between the first hinge portion 32 of the first rotating member 30 and the first connecting portion 2211 of the connecting seat 20.

[0056] Meanwhile, the second hinge portion 421 of the second rotating member 40 is rotatably connected to the second connecting portion 2231 of the connecting seat 20. For example, the second hinge portion 421 and the second connecting portion 2231 can be rotatably connected by a structure such as a ball joint pin or a fisheye bearing.

[0057] Since the first mounting part 11 and the second mounting part 12 are arranged in sequence, the first rotating member 30 and the second rotating member 40 are arranged in sequence on the mounting base 10. When the second rotating member 40 flips upward around the front-to-back axis, the first rotating member 30 rotates left and right around the vertically extending axis, and simultaneously drives the first end 51 of the first hinge arm 50 to move outward. In this way, the first rotating member 30 and the first hinge arm 50 can avoid each other by rotating to create a certain space area, which facilitates the second rotating member 40 to flip upward. Thus, the interference between the second rotating member 40 and the first hinge arm 50 can be avoided.

[0058] When the car door 300 is connected to the vehicle body 200 via the hinge assembly 100 of the scissor door in this embodiment, when force is applied to open the car door 300, the force is transmitted through the car door 300 to the connecting seat 20. The connecting seat 20 transmits the force to the first rotating member 30 and the second rotating member 40 via the first hinge arm 50 and the second hinge arm 60, respectively. This causes the first rotating member 30 to rotate around the first mounting part 11, and the second rotating member 40 to rotate around the second mounting part 12. This allows the car door 300 to open upwards and upwards in both the left and right directions. That is, when the car door 300 is opened, it opens upwards while simultaneously opening outwards in both the left and right directions, achieving a combined opening to the side and upwards. This opening method is novel and technologically advanced. Furthermore, by rotating the first rotating member 30, the first hinge arm 50 is driven to rotate around the first mounting part 11, preventing the first hinge arm 50 from entering the rotation range of the second rotating member 40, thus ensuring smooth opening of the car door 300.

[0059] It should be noted that in this embodiment, the hinge assembly 100, mounting base 10, connecting base 20, first rotating member 30, second rotating member 40, and first articulated arm 50 together constitute a four-bar linkage mechanism. The first rotating member 30 and the first articulated arm 50 form the first movable arm of the four-bar linkage mechanism, and the second rotating member 40 forms the second movable arm. During the opening of the car door 300, the first movable arm can achieve a combined upward and outward movement through the cooperation of the first rotating member 30 and the first articulated arm 50. Similarly, the second movable arm can achieve a combined upward and outward movement through the rotation of the second rotating member 40. Therefore, while achieving the same opening angle and height, the size of the hinge assembly 100 can be reduced, space occupancy decreased, the opening process becomes more effortless, and it can be applied to more small-sized vehicle models, improving its applicability.

[0060] The hinge assembly 100 of the scissor door according to the embodiments of this application can not only realize the door 300 opening outwards and upwards at the same time, achieving a compound opening of the door 300 to the side and upwards, which is novel and technologically advanced, but also reduce the volume of the hinge assembly 100 while achieving the same opening angle and height, reducing space occupation, making the door opening process more effortless, and can be applied to more small-sized vehicle models, improving applicability.

[0061] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the first rotating member 30 is rotatable relative to the first mounting portion 11 about a first axis L1, and the first hinge arm 50 is rotatable relative to the first rotating member 30 about a second axis L2. The first axis L1 and the second axis L2 intersect at a first intersection point A1. Preferably, the first intersection point A1 is located on the first rotating member 30. This allows the door 300 to slide out smoothly.

[0062] In one embodiment of this application, such as Figure 5 As shown, the hinge assembly 100 of the scissor door may further include a second hinge arm 60, which has a third end 61 and a fourth end 62. The third end 61 is rotatably connected to the second hinge portion 421, and the fourth end 62 is rotatably connected to the second connecting portion 2231. That is, the second hinge arm 60 is connected between the second hinge portion 421 of the second rotating member 40 and the second connecting portion 2231 of the connecting seat 20. In this case, the second rotating member 40 and the second hinge arm 60 constitute the second movable arm of a four-bar linkage. During the opening of the car door 300, the second movable arm can achieve a double upward (the second rotating member 40 flips upward, and the second hinge arm 60 moves upward) and outward compound movement through the cooperation of the second rotating member 40 and the second hinge arm 60. This further improves the door opening efficiency, further reduces the volume of the hinge assembly 100 while achieving the same opening angle and height, reduces space occupation, and makes the door opening process more effortless.

[0063] In one specific embodiment of this application, such as Figure 5 As shown, the second rotating member 40 is rotatable relative to the second mounting part 12 about the third axis L3, and the second hinge arm 60 is rotatable relative to the second rotating member 40 about the fourth axis L4. The first axis L1, the third axis L3 and the fourth axis L4 intersect at the second intersection point A2. Thus, the jamming phenomenon when opening and closing the car door 300 can be avoided, and the car door 300 can be smoothly slid out.

[0064] Furthermore, such as Figure 5As shown, the first intersection point A1 and the second intersection point A2 do not coincide. When the first intersection point A1 and the second intersection point A2 coincide, the movement trajectory of the door 300 during the opening process is a curved movement along a spherical surface, with a large movement distance and requiring a larger pushing force and lever arm. When the first intersection point A1 and the second intersection point A2 do not coincide, the movement trajectory of the door 300 during the opening process is a curved movement along a rugby ball surface. Under the premise of achieving the same opening angle with the same opening degree and height, by making the first intersection point A1 and the second intersection point A2 not coincide, the movement distance of the door 300 can be reduced, the opening efficiency can be improved, and the opening process can be made more effortless.

[0065] In some embodiments of this application, such as Figure 5 As shown, the second hinge arm 60 is rotatable relative to the second rotating member 40 about the fourth axis L4, and the second hinge arm 60 is rotatable relative to the second connecting part 2231 about the fifth axis L5. The fourth axis L4 and the fifth axis L5 intersect at a third intersection point A3. Preferably, the third intersection point A3 is located on the second hinge arm 60. This allows the door 300 to slide out smoothly.

[0066] Furthermore, such as Figure 5 As shown, the first intersection point A1, the second intersection point A2, and the third intersection point A3 do not coincide. Therefore, while ensuring that the door 300 opens and closes smoothly and without jamming, the opening efficiency can be improved, making it easier to open and close the door 300.

[0067] In some embodiments of this application, such as Figure 5 As shown, the first hinge arm 50 is rotatable relative to the first rotating member 30 about the second axis L2, the second hinge arm 60 is rotatable relative to the second connecting part 2231 about the fifth axis L5, and the first hinge arm 50 is rotatable relative to the first connecting part 2211 about the sixth axis L6. The second axis L2, the fifth axis L5, and the sixth axis L6 are parallel to each other. This avoids any jamming when opening and closing the door 300, ensuring smooth opening and closing of the door 300.

[0068] In some embodiments of this application, such as Figure 4 As shown, the mounting base 10 is vertically arranged. For example, the mounting base 10 is a vertically arranged plate extending front to back. The first mounting part 11 and the second mounting part 12 are both located on the upper part of the mounting base 10. The second mounting part 12 is located below the first mounting part 11 and faces the connecting base 20. For example, the first mounting part 11 is located above the second mounting part 12, the second mounting part 12 is connected to the lower end of the first mounting part 11, and the second mounting part 12 is located below and behind the first mounting part 11.

[0069] Furthermore, the first rotating member 30 is rotatably disposed on the first mounting portion 11 about the first axis L1, and the second rotating member 40 is rotatably disposed on the second mounting portion 12 about the third axis L3, wherein the first axis L1 extends vertically, and the third axis L3 extends downward from front to back. This makes opening the door easier, and while achieving the same opening angle and height, further reduces the size of the hinge assembly 100, thus reducing space occupation.

[0070] In some embodiments of this application, such as Figure 5 and Figure 7 As shown, the connecting seat 20 may include a first connecting plate 21 and a second connecting plate 22. The first connecting plate 21 extends to the left and right for connection with the door 300, and the second connecting plate 22 is connected to the front surface of the first connecting plate 21 and extends forward. The first connecting part 2211 and the second connecting part 2231 are both provided on the first connecting plate 21. As a result, the connecting seat 20 can be made compact, reducing the volume of the hinge assembly 100 and reducing space occupation.

[0071] In some examples, such as Figure 7 As shown, the first connecting plate 21 extends in the left-right direction and is provided with a door connecting hole 211. The door connecting hole 211 passes through the first connecting plate 21 in the front-back direction. There are multiple door connecting holes 211, which are arranged at intervals on the first connecting plate 21. Fasteners such as screws pass through the door connecting holes 211 to fix the connecting seat 20 to the door 300.

[0072] In one specific embodiment of this application, such as Figure 5 and Figure 7 As shown, the second connecting plate 22 is vertically arranged and extends back and forth. The second connecting plate 22 includes a first plate segment 221, a bent segment 222 and a second plate segment 223 connected sequentially from top to bottom. The first plate segment 221 and the second plate segment 223 are staggered in the left and right directions. The first plate segment 221 and the second plate segment 223 are connected by the bent segment 222. For example, the upper end of the bent segment 222 is connected to the lower end of the first plate segment 221, and the lower end of the bent segment 222 extends downward toward the second plate segment 223 at an angle, and the lower end of the bent segment 222 is connected to the upper end of the second plate segment 223.

[0073] Furthermore, such as Figure 5 As shown, the second end 52 of the first hinge arm 50 is connected to the first plate segment 221 of the second connecting plate 22, and the second end 52 of the first hinge arm 50 is located on the side of the first plate segment 221 facing the bent section 222 in the left-right direction (e.g. Figure 5(As shown on the right side of the first plate segment 221), the fourth end 62 of the second hinge arm is connected to the second plate segment 223 of the second connecting plate 22, and the fourth end 62 of the second hinge arm is located on the side of the second plate segment 223 facing the bent section 222 in the left-right direction (e.g., on the right side of the first plate segment 221). Figure 5 (The left side of the second plate segment 223 shown). As a result, the structure of the hinge assembly 100 can be further compacted, the volume can be reduced, and the space occupied by the hinge assembly 100 can be reduced.

[0074] In some embodiments of this application, such as Figures 3-5 As shown, the first hinge arm 50 is rotatably connected to the first rotating member 30 about the second axis L2. The first end 51 and the second end 52 of the first hinge arm 50 are offset in a direction parallel to the second axis L2. The first hinge arm 50 also includes a connecting section 53, one end of which (e.g. Figure 5 The front end of the connecting segment 53 shown is connected to the first end 51, and the other end of the connecting segment 53 (e.g., Figure 5 The rear end of the connecting segment 53 shown extends obliquely toward the second end 52. This allows for a more compact structure of the hinge assembly 100, reducing space occupation, while facilitating the connection of the first end 51 and the second end 52 of the first hinge arm 50 to the first movable member 30 and the connecting seat 20, respectively.

[0075] In some embodiments of this application, such as Figures 3-5 As shown, the second rotating member 40 is in a first position relative to the second mounting portion 12 about the third axis L3 (e.g., Figure 5 The position of the second rotating member 40 shown in the figure) and the second position (e.g. Figure 3 The second rotating member 40 can rotate between its position shown in the diagram. Further, the third axis L3 extends front-to-back. When the second rotating member 40 is in the first position, the second hinge portion 421 is located below the third axis L3; when the second rotating member 40 is in the second position, the second hinge portion 421 is located above the third axis L3. Thus, when the second rotating member 40 rotates from the first position to the second position, the door 300 can slide upwards. Specifically, when the second rotating member 40 is in the first position, the door 300 is in a closed state; when the second rotating member 40 is in the second position, the door 300 is in a fully open state.

[0076] In one specific embodiment of this application, the second rotating member 40 includes a first segment 41 and a second segment 42 connected sequentially. Both the first segment 41 and the second segment 42 extend along a straight line. The first segment 41 is inclined relative to the second segment 42, and the included angle between the first segment 41 and the second segment 42 is an obtuse angle. The first segment 41 is connected to the second mounting portion 12, and the second hinge portion 421 is formed on the second segment 42. This simplifies the structure of the second rotating member 40 and facilitates the smooth sliding of the door 300.

[0077] Furthermore, such as Figure 5 As shown, the third axis L3 extends downwards from front to back in the direction from front to back. In this way, when the second rotating member 40 rotates from bottom to top, the second rotating member 40 can not only push the door 300 upwards to open, but also push the door 300 outwards in the left and right directions, realizing the combined upward and outward movement of the door 300, further improving the opening efficiency.

[0078] Preferably, the second mounting portion 12 is located on the side where the inner angle of the second rotating member 40 is located. This increases the height of the door 300 and improves its opening efficiency. In other words, while achieving the same opening angle and height, the size of the hinge assembly 100 can be reduced, thus decreasing the overall volume.

[0079] In some embodiments of this application, such as Figure 3 and Figure 4 As shown, the hinge assembly 100 of the scissor door further includes a support rod 70, which can be an electric support rod 70. Both ends of the support rod 70 are hinged to the mounting base 10 and the connecting base 20, respectively. The support rod 70 is used to drive the connecting base 20 to move relative to the mounting base 10. Specifically, the support rod 70 is vertically oriented, with its lower end hinged to the lower end of the mounting base 10 and its upper end hinged to the second connecting plate 22 of the connecting base 20. When the support rod 70 is pushed upwards, it can push the connecting base 20 to move. Since the connecting base 20 is connected to the mounting base 10 through the first rotating member 30, the second rotating member 40, the first hinge arm 50, and the second hinge arm 60, under the force of the support rod 70, the connecting base 20 flips upwards and outwards. This embodiment, by setting the support rod 70, enables the automatic opening and closing of the door 300.

[0080] In one specific embodiment of this application, the mounting base 10 is a vertically oriented plate shape. A first mounting portion 11 and a second mounting portion 12 are both located on the upper part of the mounting base 10.
