Abstract
Description
Technical Field
[0001] The present application relates to the technical field of vehicle rear doors, and in particular to a rear door and a vehicle. Background Art
[0002] The automotive rear door is located at the rear of the vehicle and is generally an integral structure. Its upper part is connected to the vehicle body through hinges and hydraulic struts, and its lower part realizes the locking function between the rear door and the vehicle body through a rear door lock.
[0003] For vehicle models such as SUVs, due to the large size of the rear door, after the rear door of this integral structure is opened, the rear door extends approximately horizontally towards the rear of the vehicle, which inevitably occupies a relatively large spatial dimension in the front-rear direction. For vehicles parked with the rear of the vehicle against the wall in an indoor parking garage, opening the rear door is likely to scrape against the wall, causing damage to the automotive rear door. Summary of the Utility Model
[0004] The embodiments of the present application provide a rear door and a vehicle, in which the first sub-door and the second sub-door can be folded, reducing the space occupied during the opening process of the rear door.
[0005] In a first aspect, the embodiments of the present application provide a rear door, which includes a first sub-door, a second sub-door, and a hinge assembly. The hinge assembly includes a fixed arm and a rotating arm. The fixed arm is connected to the first sub-door, the rotating arm is connected to the second sub-door, the rotating arm is rotatably connected to the fixed arm, and a first connection structure is provided on the rotating arm for rotatably connecting a first driving strut.
[0006] Based on the rear door of the embodiments of the present application, the hinge assembly connects the first sub-door through the fixed arm, and extends the rotating arm to the second sub-door and connects it to the second sub-door to realize the rotational connection between the first sub-door and the second sub-door. The first driving strut is connected to the rotating arm through the first connection structure. The first driving strut applies an external force to the rotating arm to keep the position of the second sub-door fixed. When the first driving strut extends, the second sub-door rotates relative to the first sub-door along a first direction. When the first driving strut contracts, the second sub-door rotates relative to the first sub-door along a second direction, enabling the second sub-door and the first sub-door to be at least partially folded, reducing the space occupied by the rear door during and after the opening process; at the same time, integrating the first connection structure of the first driving strut into the hinge assembly improves the integration of the vehicle.
[0007] In some embodiments of the present application, the rotating arm is rotatably connected to the fixed arm at a first hinge point, and the first connection structure is used to rotatably connect to the first driving strut at a second hinge point, and the distance between the first hinge point and the second hinge point is greater than or equal to 130 mm.
[0008] Based on the above embodiments, when the first driving strut expands and contracts, the first driving strut applies an external force to the rotating arm at the second hinge point. According to the torque formula T = Fd, the greater the distance between the first hinge point and the second hinge point, the greater the torque exerted on the rotating arm under the premise that the external force applied by the first driving strut to the rotating arm is the same. That is, the second sub-door is more likely to rotate relative to the first sub-door. Within this range, it is ensured that there is a sufficient distance between the first hinge point and the second hinge point.
[0009] In some embodiments of the present application, the first connection structure is configured as a ball head pin protruding from the surface of the rotating arm.
[0010] Based on the above embodiments, a ball head pin is convexly provided on the surface of the rotating arm. The ball head pin will not damage the structure of the rotating arm, and the ball head pin cooperates with the first driving strut, and there is good rotational performance between the first driving strut and the ball head pin.
[0011] In some embodiments of the present application, the rotating arm includes a first connection section, a second connection section, and a main body section. The first connection section is rotatably connected to the fixed arm; the second connection section is connected to the second sub-door; one end of the main body section is connected to the first connection section, and the other end is connected to the second connection section, and the first connection structure is provided on the main body section.
[0012] Based on the above embodiments, the first connection section is rotatably connected to the fixed arm to realize the rotational connection between the rotating arm and the fixed arm. The second connection section is connected to the second sub-door to realize the connection between the rotating arm and the second sub-door. The main body section extends from the first sub-door to the second sub-door, and one end is connected to the first connection section and the other end is connected to the second connection section, realizing the rotational connection between the first sub-door and the second sub-door at a long distance.
[0013] In some embodiments of the present application, the main body section includes a main body sub-section and a transition sub-section;
[0014] The number of the transition sub-sections is one. One end of the transition sub-section is connected to the main body sub-section, and the other end is connected to the first connection section. The transition sub-section is inclined in the vehicle body width direction; or,
[0015] The number of the transition sub-sections is one. One end of the transition sub-section is connected to the main body sub-section, and the other end is connected to the second connection section. The transition sub-section is inclined in the vehicle body width direction; or,
[0016] The number of the transition sub-sections is two. One transition sub-section has one end connected to the main body sub-section and the other end connected to the first connection section, and the other transition sub-section has one end connected to the main body sub-section and the other end connected to the second connection section. The transition sub-sections are inclined in the vehicle body width direction.
[0017] Based on the above embodiments, during the process that the main body section extends from the first sub-door to the second sub-door, it is adjusted by a transition sub-section.
[0018] In some embodiments of the present application, the rotating arm is provided with a reinforcing rib, the reinforcing rib is arranged on the transition sub-section, and extends to the main body sub-section and the adjacent first connecting section; and / or, extends to the main body sub-section and the adjacent second connecting section.
[0019] Based on the above embodiments, the reinforcing rib can enhance the structural strength of the rotating arm. Especially for the bending parts between the transition sub-section and the main body sub-section, between the transition sub-section and the first connecting section, or between the transition sub-section and the second connecting section, stress concentration is likely to occur. The reinforcing rib extends from the transition sub-section to the main body sub-section and the adjacent first connecting section or second connecting section, which can ensure that the above-mentioned bending parts have sufficient structural strength.
[0020] In some embodiments of the present application, the fixed arm includes a first connecting portion and a second connecting portion. The first connecting portion is connected to the first sub-door; the second connecting portion is connected to the first connecting portion, and the second connecting portion is rotatably connected to the first connecting section.
[0021] Based on the above embodiments, the first connecting portion realizes the fixed connection between the fixed arm and the first sub-door, and the second connecting portion realizes the rotational connection between the fixed arm and the rotating arm.
[0022] In some embodiments of the present application, a second connecting structure is provided on the second connecting portion, and the second connecting structure is used for rotatably connecting the second driving strut.
[0023] Based on the above embodiments, integrating the second connecting structure for rotatably connecting the second strut into the fixed arm improves the integration of the vehicle.
[0024] In some embodiments of the present application, the first sub-door is arranged along the vehicle body length direction and is flush with the vehicle body roof; the second sub-door is arranged at an angle with the first sub-door and is located at the rear end of the vehicle body.
[0025] Based on the above embodiments, the first sub-door and the second sub-door form a hatchback rear door. When the rear door is opened, the first sub-door rotates along a first direction around the rotation connection axis with the vehicle body. During this process, the first driving strut contracts, and the second sub-door rotates along a second direction around the hinge point of the fixed arm and the rotating arm, so that the first sub-door and the second sub-door are folded.
[0026] In a second aspect, an embodiment of the present application provides a vehicle, including a vehicle body, a first driving strut, and the rear door as described above. The second sub-door is rotatably connected to the vehicle body roof; one end of the first driving strut is rotatably connected to the first connecting structure, and the other end is rotatably connected to the vehicle body.
[0027] For the vehicle according to the embodiment of the present application, due to having the above-mentioned rear door, when the first sub-door and the second sub-door of the vehicle are folded, the rear door of the vehicle occupies a relatively small space in the maximum opening position, during the opening process, and during the closing process.

Detailed Embodiments
[0033] In order to make the purpose, technical solutions, and advantages of the present application clearer, the following further details the present application in conjunction with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.
[0034] The back door of an automobile is located at the rear of the automobile and is generally an integral structure. Its upper part is connected to the vehicle body through a hinge and a hydraulic strut, and its lower part realizes the locking function of the back door and the vehicle body through a back door lock.
[0035] For models such as SUVs, due to the large back door, after the back door of this integral structure is opened, the back door extends approximately horizontally backward of the vehicle, which inevitably occupies a relatively large space dimension in the front-rear direction. For vehicles parked with the rear of the vehicle against the wall in an indoor parking garage, opening the back door is likely to scrape the wall, causing damage to the back door of the automobile.
[0036] To solve the above technical problems, please refer to Figures 1 to 3 As shown, the embodiment of the present application provides a rear door, which can be folded between the first sub-door 10 and the second sub-door 20, reducing the space occupied during the opening process of the rear door.
[0037] The rear door includes a first sub-door 10, a second sub-door 20, and a hinge assembly 30. The hinge assembly 30 includes a fixed arm 31 and a rotating arm 32. The fixed arm 31 is connected to the first sub-door 10, the rotating arm 32 is connected to the second sub-door 20, the rotating arm 32 is rotatably connected to the fixed arm 31, and a first connection structure 324 is provided on the rotating arm 32 for rotatably connecting a first driving strut.
[0038] The first sub-door 10 and the second sub-door 20 in the embodiment of the present application together form the rear door. In some embodiments of the present application, both the first sub-door 10 and the second sub-door 20 are at the rear end of the vehicle body. At this time, the first sub-door 10 and the second sub-door 20 form a traditional tailgate. The first sub-door 10 is rotatably connected to the vehicle body at the rear end of the vehicle body. During the process of the first sub-door 10 rotating around the vehicle body in the first direction, the second sub-door 20 rotates relative to the first sub-door 10 in the second direction, and the rotation directions of the first direction and the second direction are opposite.
[0039] In some other embodiments of the present application, the first sub-door 10 is arranged along the length direction of the vehicle body and is flush with the vehicle body roof; the second sub-door 20 is arranged at an angle with the first sub-door 10 and is located at the rear end of the vehicle body. At this time, the first sub-door 10 and the second sub-door 20 form a hatchback rear door. The first sub-door 10 is rotatably connected to the roof of the vehicle body. When the rear door is opened, the first sub-door 10 rotates relative to the vehicle body in the first direction, and the second sub-door 20 rotates relative to the first sub-door 10 in the second direction, and the rotation directions of the first direction and the second direction are opposite.
[0040] The first driving strut is used to support the second sub-door 20 to fix the position of the second sub-door 20 relative to the first sub-door 10.
[0041] Based on the rear door of the embodiment of the present application, the hinge assembly 30 connects the first sub-door 10 through the fixed arm 31, and extends the rotating arm 32 from the fixed arm 31 to the second sub-door 20 and connects it to the second sub-door 20, realizing the rotational connection between the first sub-door 10 and the second sub-door 20. The first driving strut is connected to the rotating arm 32 through the first connection structure 324, that is, the first driving strut applies an external force to the rotating arm 32 to keep the position of the second sub-door 20 fixed. When the first driving strut expands and contracts, the second sub-door 20 rotates relative to the first sub-door 10, that is, integrating the connection mechanism connecting the first driving strut into the hinge assembly 30, improving the integration of the vehicle and simplifying the vehicle body structure.
[0042] In some embodiments of the present application, the rotating arm 32 is rotatably connected to the fixed arm 31 at the first hinge point, and the first connection structure 324 is used to be rotatably connected to the first driving strut at the second hinge point. The distance between the first hinge point and the second hinge point is greater than or equal to 130 mm. For example, 135 mm, 140 mm, 145 mm, 150 mm, or 155 mm, etc. When the first driving strut expands and contracts, the first driving strut applies an external force to the rotating arm 32 at the second hinge point. According to the torque formula T = Fd (where F is the magnitude of the force, d is the length of the force arm, that is, the perpendicular distance from the acting point to the axis), the greater the distance between the first hinge point and the second hinge point, on the premise that the external force applied by the first driving strut to the rotating arm 32 is the same, the greater the torque received by the rotating arm 32, that is, the second sub-door 20 is more likely to rotate relative to the first sub-door 10, or the first driving strut is more likely to support the second sub-door 20.
[0043] It can be understood that in the embodiments of the present application, the distance between the first hinge point and the second hinge point can also be set below 130 mm. However, in this case, a first driving strut with a greater supporting force is required.
[0044] In some embodiments of the present application, the first connection structure 324 is configured as a ball head pin protruding from the surface of the rotating arm 32. Protruding a ball head pin on the surface of the rotating arm 32 will not damage the structure of the rotating arm 32, and the ball head pin cooperates with the first driving strut, and there is good rotational performance between the first driving strut and the ball head pin.
[0045] In the embodiments of the present application, the ball head pin can be made of wear-resistant material to reduce the mutual wear between the ball head pin and the first driving strut during long-term use. And in the embodiments of the present application, the ball head pin and the rotating arm 32 can be integrally provided, or the ball head pin and the rotating arm 32 can be threadedly connected. In this way, the easily worn ball head pin can be replaced.
[0046] In some embodiments of the present application, the rotating arm 32 includes a first connection section 321, a second connection section 322, and a main body section 323. The first connection section 321 is rotatably connected to the fixed arm 31; the second connection section 322 is connected to the second sub-door 20; one end of the main body section 323 is connected to the first connection section 321, and the other end is connected to the second connection section 322. The main body section 323 is provided with the first connection structure 324. The rotational connection between the rotating arm 32 and the fixed arm 31 is realized by the rotational connection between the first connection section 321 and the fixed arm 31. The connection between the rotating arm 32 and the second sub-door 20 is realized by the connection between the second connection section 322 and the second sub-door 20. The main body section 323 extends from the first sub-door 10 to the second sub-door 20, and one end is connected to the first connection section 321 and the other end is connected to the second connection section 322, realizing the long-distance rotational connection between the first sub-door 10 and the second sub-door 20.
[0047] The first connecting section 321 is used for rotatably connecting with the fixed arm 31. In the embodiment of the present application, the first connecting section 321 and the fixed arm 31 are rotatably connected by arranging a rotating shaft. Both the first connecting section 321 and the fixed arm 31 are rotatably sleeved for rotational connection.
[0048] The second connecting section 322 is used for connecting with the second sub-door 20. In the embodiment of the present application, the second connecting section 322 and the back door are fixedly connected by bolts. To ensure the connection strength between the second connecting section 322 and the back door, at least two connecting holes are provided on the second connecting section 322, which can prevent the back door from rotating relative to the second connecting section 322.
[0049] The main body section 323 is used for connecting the first connecting section 321 and the second connecting section 322. In the embodiment of the present application, the main body section 323 extends from the first sub-door 10 to the second sub-door 20. Therefore, the main body section 323 has a relatively long length. To ensure the structural strength of the main body section 323, in the embodiment of the present application, at least the main body section 323 of the rotating arm 32 is made of high-strength material, such as steel.
[0050] In some embodiments of the present application, the main body section 323 includes a main body sub-section 3231 and a transition sub-section 3232; the number of the transition sub-sections 3232 is one. One end of the transition sub-section 3232 is connected to the main body sub-section 3231, and the other end is connected to the first connecting section 321. The transition sub-section 3232 is inclined along the vehicle body width direction.
[0051] Since the first hinge point and the connection point of the rotating arm 32 with the first sub-door 10 are misaligned in the vehicle body width direction, when the main body section 323 extends from the first sub-door 10 to the second sub-door 20, it needs to have an extension amount in the vehicle body width direction, so that one end of the rotating arm 32 can be rotatably connected to the fixed arm 31, and the other end can be connected to the second back door. The main body sub-section 3231 in the main body section 323 extends along the vehicle body length direction and / or the vehicle body height direction. The transition sub-section 3232 is arranged to extend along the vehicle body length direction and / or the vehicle body height direction and at the same time extend along the vehicle body width direction, so as to realize that the main body section 323 has an extension amount in the vehicle body width direction, which is convenient for the hinge assembly 30 to connect the first sub-door 10 and the second sub-door 20.
[0052] In some other embodiments of the present application, the number of the transition sub-sections 3232 is one. One end of the transition sub-section 3232 is connected to the main body sub-section 3231, and the other end is connected to the second connecting section 322. The transition sub-section 3232 is inclined along the vehicle body width direction.
[0053] Similarly, arranging the transition sub-section 3232 between the main body sub-section 3231 and the second connecting section 322 can also realize that the main body section 323 has an extension amount in the vehicle body width direction, which is convenient for the hinge assembly 30 to connect the first sub-door 10 and the second sub-door 20.
[0054] In still some other embodiments of the present application, the number of the transition sub-segments 3232 is two. One end of one transition sub-segment 3232 is connected to the main body sub-segment 3231, and the other end is connected to the first connection segment 321. One end of the other transition sub-segment 3232 is connected to the main body sub-segment 3231, and the other end is connected to the second connection segment 322. The transition sub-segments 3232 are arranged obliquely along the vehicle body width direction.
[0055] In some embodiments of the present application, the rotating arm 32 is provided with a reinforcing rib 325. The reinforcing rib 325 is arranged on the transition sub-segment 3232 and extends to the adjacent main body sub-segment 3231 and the first connection segment 321; and / or, extends to the adjacent main body sub-segment 3231 and the second connection segment 322.
[0056] The reinforcing rib 325 can enhance the structural strength of the rotating arm 32. Particularly for the bending positions between the transition sub-segment 3232 and the main body sub-segment 3231, between the transition sub-segment 3232 and the first connection segment 321, or between the transition sub-segment 3232 and the second connection segment 322, stress concentration is likely to occur. The reinforcing rib 325 extends from the transition sub-segment 3232 to the main body sub-segment 3231 and the adjacent first connection segment 321 or the second connection segment 322, which can ensure that the above-mentioned bending positions have sufficient structural strength.
[0057] The reinforcing rib 325 in the embodiments of the present application can be an independent reinforcing rib 325 strip and is welded to the rotating arm 32; the reinforcing rib 325 in the embodiments of the present application can also be a reinforcing protrusion formed by stamping the rotating arm 32 on the reinforcing rib 325.
[0058] In some embodiments of the present application, the fixed arm 31 includes a first connection portion 311 and a second connection portion 312. The first connection portion 311 is connected to the first sub-door 10; the second connection portion 312 is connected to the first connection portion 311, and the second connection portion 312 is rotatably connected to the first connection segment 321. The first connection portion 311 realizes the fixed connection between the fixed arm 31 and the first sub-door 10, and the second connection portion 312 realizes the rotational connection between the fixed arm 31 and the rotating arm 32.
[0059] In the embodiments of the present application, both the first connection portion 311 and the second connection portion 312 are configured as connecting plates. The first connection portion 311 is arranged to fit the inner wall of the first sub-door 10 and is connected to the first sub-door 10 through a connecting member; the second connection portion 312 protrudes from the side of the first connection portion 311 away from the first sub-door 10.
[0060] In some embodiments of the present application, a second connection structure 313 is provided on the second connection portion 312. The second connection structure 313 is used for rotatably connecting the second driving strut. Integrating the second connection structure 313 that rotatably connects to the second strut into the fixed arm 31 improves the integration of the vehicle. The second connection structure 313 in the embodiments of the present application can be configured as a ball head pin.
[0061] In a second aspect, an embodiment of the present application provides a vehicle, including a vehicle body, a first driving strut, and a rear door as described above. The second sub-door 20 is rotatably connected to the vehicle body roof; one end of the first driving strut is rotatably connected to the first connection structure 324, and the other end is rotatably connected to the vehicle body.
[0062] One end of the first driving strut is connected to the vehicle body, and the other end is connected to the first connection structure 324. During the rotation of the first sub-door 10 around the vehicle body, the first driving strut gradually shortens, causing the second sub-door 20 to rotate relative to the first sub-door 10 in a second direction, thereby folding the first sub-door 10 and the second sub-door 20.
[0063] Based on the vehicle of the embodiments of the present application, due to the above-mentioned rear door, when the first sub-door 10 and the second sub-door 20 of the vehicle are folded, the rear door of the vehicle occupies a relatively small space in the maximum opening position, during the opening process, and during the closing process.
[0064] The vehicle in the embodiments of the present application further includes a second driving strut. The second driving strut is used for driving the first sub-door 10 to rotate relative to the vehicle body in a first direction. One end of the second driving strut is connected to the vehicle body, and the other end is connected to the second connection structure 313. When the second driving strut extends, the first sub-door 10 and the second sub-door 20 rotate relative to the vehicle body in the first direction.
