[0037] See also Figure 1 The utility model provides a vehicle, which includes a body and a door structure. The door structure includes a door body and a hinge structure 100 provided by the utility model. The door body is fixedly connected to a connecting swing arm 40 of the hinge structure 100, and the body is fixedly connected to a mounting base 10 of the hinge structure 100.

[0038] In one embodiment, the mounting base 10 of the hinge structure 100 is connected to a side wall of a vehicle.

[0039] See also Figure 2The hinge structure 100 includes a mounting base 10, a sliding arm 20, a ball head arm 30, a connecting swing arm 40 and a first rotating arm 50. The sliding arm 20 is slidably connected to the mounting base 10; the ball head arm 30 is rotationally connected to the sliding arm 20; the connecting swing arm 40 is rotationally connected to an end of the ball head arm 30 away from the sliding arm 20; the first rotating arm 50 is rotationally connected to both the mounting base 10 and the connecting swing arm 40.

[0040] By slidably connecting the slide arm 20 with the mounting base 10, the slide arm 20 guides the rotation of the connected swing arm 40. During assembly, the assembly accuracy requirement is lower than that of the spatial spherical four-bar structure, and it is not necessary to ensure that the four axes intersect at one point. The slide arm 20 slides on the mounting base 10, which makes the overall structure of the hinge structure 100 compact relative to rotation.

[0041] During the door opening process, the door can open sideways relative to the vehicle body, that is, the hinge structure 100 can open the door sideways; or first open sideways and then rotate upwards to close, that is, the hinge structure 100 can open the door in a scissor-like manner; or the hinge structure 100 can be used for both sideways and scissor-like door opening, which is beneficial to saving the vehicle body mold cost and ensuring that the door lock can continue to use the opening and closing action of the side door arrangement state. The closing process of the door is opposite to the opening action of the door.

[0042] During the process of opening or closing the door, the connecting swing arm 40 simultaneously performs unidirectional rotational motion around the connecting swing arm 40 and the mounting base 10. During the rotation of the connecting swing arm 40, one end of the sliding arm 20 is driven to rotate through the ball head arm 30, and one end of the sliding arm 20 is slidingly connected to the mounting base 10. The sliding arm 20 rotates under the drive of the ball head arm 30 and converts the rotational motion into a sliding motion, so that the same distance is always maintained from the surface of the mounting base 10, making the overall structure of the hinge structure 100 compact.

[0043] The hinge structure 100 in this embodiment is a motion mechanism of three revolute pairs, one spherical pair and one sliding pair, and finally realizes a sliding guide hinge structure 100, so that the motion trajectory of the door body is unique, and the entire hinge structure 100 is a single degree of freedom structure with good motion stability. Among them, one end of the first rotating arm 50 forms a revolute pair at the mounting base 10, and the other end of the first rotating arm 50 forms a revolute pair at the connection swing arm 40, one end of the sliding arm 20 forms a revolute pair at the ball head arm 30, the ball head arm 30 forms a spherical pair at the connection swing arm 40, and the other end of the sliding arm 20 forms a sliding pair at the mounting base 10.

[0044] Please combine Figure 3 For example, the sliding arm 20 includes a connecting rod 21 and a rolling member 22, one end of the connecting rod 21 is connected to the rolling member 22, the rolling member 22 is slidingly connected to the mounting base 10, and the other end of the connecting rod 21 is rotatably connected to the ball head arm 30.

[0045] One end of the connecting rod 21 is equipped with one or more rolling elements 22, and the rolling elements 22 are slidably connected to the mounting base 10. The rolling elements 22 can slide linearly along the surface of the mounting base 10, or the rolling elements 22 can slide in an arc along the surface of the mounting base 10. The other end of the connecting rod 21 is rotatably connected to the ball head arm 30. When the connecting swing arm 40 rotates relative to the ball head arm 30, the connecting swing arm 40 drives one end of the connecting rod 21 to rotate through the ball head arm 30. Since one end of the connecting rod 21 is slidably connected to the mounting base 10 through the rolling elements 22, the connecting rod 21 is driven by the ball head arm 30 to simultaneously rotate relative to the ball head arm 30 and slide relative to the mounting base 10.

[0046] The rolling element 22 may be a pulley or a rolling bearing, so that the rolling element 22 drives the slide arm 20 to slide relative to the mounting base 10 .

[0047] For example, the sliding arm 20 further includes a first fixed shaft 23 , the first fixed shaft 23 is connected to the connecting rod 21 , and the rolling element 22 is rotatably connected to the first fixed shaft 23 .

[0048] In this embodiment, the first fixed shaft 23 is fixedly connected to the end of the connecting rod 21 away from the ball head arm 30. The rolling element 22 is a rolling bearing, and the number of the rolling bearings is two, each of which is rotatably connected to a first fixed shaft 23, which is conducive to ensuring the stability of the sliding arm 20 sliding relative to the mounting base 10.

[0049] For example, the mounting base 10 includes a slide rail 11 , and the rolling member 22 cooperates with the slide rail 11 , and the rolling member 22 rolls on the side wall of the slide rail 11 .

[0050] The slide rail 11 may be in a U-shaped structure, with the rolling element 22 embedded in the slide rail 11 to roll on the inner wall surface of the slide rail 11; or, the slide rail 11 may be in a T-shaped structure, with the rolling element 22 embedded in the side wall of the slide rail 11 to roll on the outer wall surface of the slide rail 11. The rolling element 22 slides along the extension direction of the slide rail 11 during rolling on the slide rail 11. The slide rail 11 may be a linear slide rail 11 or an arcuate slide rail 11.

[0051] Please combine Figure 4 In this embodiment, the slide rail 11 is a linear slide rail 11 , and the rolling element 22 performs linear reciprocating motion on the side wall of the slide rail 11 .

[0052] For example, the mounting base 10 further includes a base body 12 and a boss 13 . The boss 13 is fixed on the base body 12 , and the slide rail 11 is mounted on the boss 13 .

[0053] The boss 13 and the seat body 12 can be connected and fixed by bolt connection, clamping or welding. The boss 13 and the slide rail 11 can be connected and fixed by bolt connection, so that the slide rail 11 can be detached and adjusted relative to the boss 13. The boss 13 and the slide rail 11 can also be connected and fixed by clamping or welding.

[0054] Usually, the flatness of the seat body 12 is low. By setting a boss 13 on the seat body 12, the flatness of the boss 13 is easier to control than the flatness of the seat body 12. Installing the slide rail 11 on the boss 13 is beneficial to improving the assembly accuracy of the rolling member 22 and the slide rail 11, thereby improving the overall assembly accuracy of the hinge structure 100.

[0055] Please combine Figure 5 For example, the ball head arm 30 also includes a second rotating arm 31 and a ball head 32 , one end of the second rotating arm 31 is rotatably connected to the other end of the sliding arm 20 , and the other end of the second rotating arm 31 is fixedly connected to the ball head 32 .

[0056] The ball head 32 is a spherical structure, and the ball head 32 is connected to the connecting swing arm 40 in the form of a spherical pair. When the ball head 32 is assembled, the ball head 32 can be inserted into the connecting swing arm 40 from the outside of the vehicle to the inside of the vehicle. The connecting swing arm 40 can rotate 360 ​​degrees in space relative to the ball head arm 30, and with the cooperation of the first rotating arm 50, it can realize a combined motion of first opening sideways and then rotating upward.

[0057] Please combine Figure 6 The second rotating arm 31 is located between the seat body 12 and the ball head 32, and the second rotating arm 31 is located between the connecting rod 21 and the seat body 12. In other words, the second rotating arm 31 is closer to the seat body 12 relative to the ball head 32, and the second rotating arm 31 is closer to the seat body 12 than the connecting rod 21, thereby making the overall structure of the hinge structure 100 compact.

[0058] Furthermore, the connecting rod 21 is located between the second rotating arm 31 and the connecting swing arm 40 , that is, the connecting rod 21 is closer to the seat body 12 than the connecting swing arm 40 , thereby further improving the overall compactness of the hinge structure 100 .

[0059] The second rotating arm 31 and the connecting rod 21 form a revolute pair, and the ball head 32 and the connecting swing arm 40 form a spherical pair. The connecting swing arm 40 rotates around the center point of the ball head 32. The center point of the ball head 32 can be on the axis connecting the second rotating arm 31 and the connecting rod 21 in real time, and can also be offset from the axis connecting the second rotating arm 31 and the connecting rod 21.

[0060] Please combine Figure 7For example, the slide arm 20 also includes a second fixed shaft 24, which is rotatably connected to the second rotating arm 31, and the first fixed shaft 23 of the slide arm 20 has a first axis oo1, which is parallel to the second axis oo2 of the second fixed shaft 24.

[0061] The second fixed shaft 24 is fixed on the end of the connecting rod 21 away from the rolling element 22, and the second rotating arm 31 is installed on the second fixed shaft 24. During the movement of the connecting rod 21, the second axis oo2 of the second fixed shaft 24 is parallel to the first axis oo1 of the first fixed shaft 23 in real time, so that the connecting rod 21 is easy to process and produce, which is beneficial to improve the output of the hinge structure 100.

[0062] For example, the connecting swing arm 40 includes a ball head cover 41 , and the ball head cover 41 is rotatably connected to the ball head 32 .

[0063] The ball head 32 is embedded in the ball head cover 41 , and the ball head cover 41 is adapted to the ball head 32 . The ball head 32 can realize spherical rotation with the cooperation of the ball head cover 41 , and the connecting swing arm 40 rotates under the guidance of the ball head cover 41 .

[0064] Please combine Figure 5 For example, the ball head cover 41 includes a limiting end cover 411 and a mounting groove 412 , the mounting groove 412 has an opening 413 , the limiting end cover 411 is located on a side of the mounting groove 412 away from the opening 413 , and the limiting end cover 411 is used to limit the ball head 32 .

[0065] The ball head 32 can be embedded in the installation groove 412 from the opening 413. When the ball head cover 41 rotates with the connecting swing arm 40, the limiting end cover 411 limits the ball head 32 to prevent the ball head cover 41 from separating from the ball head 32, thereby ensuring the stability of the rotation of the connecting swing arm 40.

[0066] For example, the hinge structure 100 further includes a buffer member 60 , which is installed in the installation groove 412 . The buffer member 60 forms a receiving space 61 , and the ball head 32 is received in the receiving space 61 .

[0067] The buffer 60 can be a wear-resistant bushing. The material of the buffer 60 includes PA6 or other wear-resistant high-strength plastics. When the connecting swing arm 40 rotates, the ball head 32 will not directly cause wear to the ball head cover 41, which is beneficial to improving the structural life of the ball head cover 41.

[0068] See also Figure 8 For example, the mounting base 10 further includes a fixed bracket 14 , one end of the first rotating arm 50 is rotatably connected to the fixed bracket 14 , and the other end of the first rotating arm 50 is rotatably connected to the connecting swing arm 40 .

[0069] The fixed bracket 14 is fixed on the base body 12 , the first rotating arm 50 rotates around the fixed bracket 14 , and the connecting swing arm 40 rotates around the fixed bracket 14 on the first rotating arm 50 to realize the upward rotation of the connecting swing arm 40 .

[0070] Please combine Fig. 9 The fixed bracket 14 and the first rotating arm 50 play a role in bearing the weight of the door body or preventing it from sinking during the rotation of the connecting swing arm 40.

[0071] For example, the first rotating arm 50 rotates along the third axis oo3 relative to the fixed bracket 14, and the first rotating arm 50 rotates along the fourth axis oo4 relative to the connecting swing arm 40, and the third axis oo3 is arranged at an angle to the fourth axis oo4.

[0072] Please combine Figure 8 For example, the fixed bracket 14 includes a third fixed shaft, one end of the first rotating arm 50 is rotatably connected to the third fixed shaft, the third fixed shaft has a third axis oo3, the connecting swing arm 40 includes a fourth fixed shaft 42, the other end of the first rotating arm 50 is rotatably connected to the fourth fixed shaft 42, the fourth fixed shaft 42 has a fourth axis oo4, and the third axis oo3 intersects the fourth axis oo4. A limiting member is also provided on the mounting base 10 for limiting the first rotating arm 50 to prevent the first rotating arm 50 from rotating excessively during the door opening process. The limiting member can perform hard limiting when the first rotating arm 50 rotates around the third axis oo3 to between 90° and 120°.

[0073] Furthermore, an electric spring, a pneumatic spring or a balancing spring may be provided at the fixed bracket 14 to perform a soft stop limit when the first rotating arm 50 rotates around the third axis oo3 to a position between 85° and 115° during the door opening process, thereby playing a buffering role.

[0074] During the rotation of the connecting swing arm 40, the third axis oo3 of the third fixed axis always remains at the same position. As the connecting swing arm 40 rotates in space, the position of the fourth fixed axis 42 changes in real time, and the fourth axis oo4 also changes in real time, and the third axis oo3 always intersects with the fourth axis oo4. During the rotation of the first rotating arm 50, there is always an acute angle relationship between the fourth axis oo4 and the third axis oo3, making the overall structure of the hinge structure 100 compact.

[0075] The rotation process of the connecting swing arm 40 presents an arc-shaped motion trajectory along two different directions in space. The motion trajectory can be shown as follows: Fig.10 As shown by the dotted arrow in the figure, for example, the motion trajectory of the connecting swing arm 40 is the cosine state equation motion trajectory, realizing the combined motion action of first opening sideways and then rotating upward. The side opening angle of the connecting swing arm 40 can be less than 90°, and its upward rotation angle can be less than 50°.

[0076] In addition, when the door is closed, the first rotating arm 50, the second rotating arm 31, and the connecting rod 21 are as parallel to the surface of the seat body 12 as possible, which is conducive to compressing the first rotating arm 50, the second rotating arm 31, the connecting rod 21 and the seat body 12 to the same plane as much as possible, making the overall structure of the hinge structure 100 compact.

[0077] Please combine Fig.11 For example, the connecting swing arm 40 also includes a ball pin mounting seat 43, and the number of the ball pin mounting seats 43 can be two, and the two ball pin mounting seats 43 are used to connect the electric spring, the pneumatic spring or the balance spring.

[0078] Each ball pin mounting seat 43 is provided with ribs 44 for improving the local rigidity of the ball pin mounting seat 43 and the stability of the door body control by the connecting swing arm 40 .

[0079] The opening process of the door structure of this embodiment can be described as follows:

[0080] When the connecting swing arm 40 starts to open, the first rotating arm 50, under the action of the electric spring, pneumatic spring or balance spring, simultaneously rotates around the third axis oo3 and the fourth axis oo4. At this time, the connecting swing arm 40 drives the ball head cover 41 and the ball head 32 to rotate spherically, and drives the connecting rod 21 to rotate through the second rotating arm 31. The connecting rod 21 slides at the same time under the guidance of the rolling element 22 and the slide rail 11, and finally forms a sliding guide hinge structure 100.

[0081] The door closing process is opposite to the above-mentioned door opening process and will not be described in detail.

[0082] The above are some implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications are also considered to be within the scope of protection of the present application.
