[0033] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0034] The following describes a tailgate opening and closing system 100 according to an embodiment of the present invention with reference to the accompanying drawings.

[0035] Reference Figure 1-Figure 3 According to the first embodiment of the utility model, the tailgate opening and closing system 100 comprises: a tailgate 2 and a support rod 3, wherein the tailgate 2 is hinged to the rear frame 1 of the vehicle. That is, the tailgate 2 can rotate around the central axis of the hinge with the rear frame 1 to open and close the trunk 81 of the vehicle.

[0036] For example, the rear frame 1 includes a top beam and a side beam 12, the top beam extends in the width direction of the vehicle, and one end of the side beam 12 is connected to the top beam; optionally, there are two side beams 12, the two side beams 12 are respectively connected to the two ends of the top beam in the width direction, and the other end of the side beam 12 extends in the direction away from the front of the vehicle; optionally, the rear frame 1 also includes a rear sill beam, the rear sill beam extends in the width direction of the vehicle, and in the length direction of the vehicle, the rear sill beam is located at the rear side of the top beam, and the side beam 12 is connected to the top beam and the rear sill beam.

[0037] The support rod 3 is retractable, for example, the support rod 3 may be an electric push rod, the support rod 3 may also be a hydraulic push rod, or the support rod 3 may also be a pneumatic push rod.

[0038] The support rod 3 includes a door end 31 and a frame end 32, wherein the frame end 32 is used for rotationally connecting with the rear frame 1, for example, the frame end 32 can be rotatably connected to the side beam 12. The door end 31 is rotatably connected to the tailgate 2; on the first projection plane, the angle between the orthographic projection formed by the support rod 3 on the first projection plane and the width direction of the vehicle is greater than or equal to 75° and less than or equal to 105°, wherein the first projection plane is perpendicular to the length direction of the vehicle.

[0039] For example, the angle between the orthographic projection formed by the support rod 3 on the first projection plane and the width direction of the vehicle can be 75°, 76°, 77°, 78°, 79°, 80°, 81°, 82°, 83°, 84°, 85°, 86°, 87°, 88°, 89°, 90°, 91°, 92°, 93°, 94°, 95°, 96°, 97°, 98°, 99°, 100°, 101°, 102°, 103°, 104°, and 105°.

[0040] The closer the angle between the orthographic projection formed by the support rod 3 on the first projection plane and the width direction of the vehicle is to 90°, the smaller the displacement amplitude of the support rod 3 in the width direction of the vehicle when the tailgate 2 is opened and closed, the smaller the space occupied by the support rod 3 in the width direction of the vehicle when the support rod 3 moves, and the smaller the movement envelope of the support rod 3.

[0041] It needs to be explained that the motion envelope of the support rod 3 refers to: the volume swept by the support rod 3 during the opening and closing process.

[0042] By setting the angle between the orthographic projection formed by the support rod on the first projection plane and the width direction of the vehicle to be greater than or equal to 75° and less than or equal to 105°, when the tailgate rotates, the displacement amplitude of the support rod in the width direction of the vehicle is smaller, so that the space occupied by the support rod in the width direction of the vehicle when it moves can be smaller, the movement envelope of the support rod is smaller, the restriction on the shape seam of the tailgate opening and closing system is reduced, and the freedom of vehicle design is improved.

[0043] According to some embodiments of the present invention, the distance between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle is 0-10 cm. For example, the distance between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle can be 0, 1 cm, 2 cm, 3 cm, 4 cm, 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm.

[0044] The smaller the distance between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle, the smaller the space occupied by the support rod 3 in the width direction of the vehicle when the support rod 3 moves, and the smaller the movement envelope of the support rod 3. Setting the distance between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle to 0-10 cm can maintain the movement envelope of the support rod 3 within a smaller range, thereby reducing the limitation of the shape seam of the tailgate opening and closing system 100 and improving the freedom of vehicle design.

[0045] For example, the distance between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle can be 0, that is, the orthographic projection formed by the support rod 3 on the first projection plane is perpendicular to the width direction of the vehicle. In other words, the angle between the orthographic projection formed by the support rod 3 on the first projection plane and the width direction of the vehicle is 90°.

[0046] In the process of opening the tailgate 2, the tailgate 2 can drive the support rod 3 to move and stretch the support rod 3. Since the distance between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle is 0, and the rotation plane of the tailgate 2 is perpendicular to the width direction of the vehicle, in the process of opening the tailgate 2, the support rod 3 is only stretched on the plane perpendicular to the width direction of the vehicle, that is, the movement trajectory of the support rod 3 is on the plane perpendicular to the width direction of the vehicle, so that the space occupied by the support rod 3 in the width direction of the vehicle is small when the support rod 3 moves, and the movement envelope of the support rod 3 is small, which reduces the limitation of the shape seam of the tailgate opening and closing system 100 and improves the freedom of vehicle design. In this way, the support rod 3 can be applied to tailgates 2 with various opening and closing forms, for example, the tailgate 2 can be an ordinary hatchback door, or a gull-wing door.

[0047] In the process of closing the tailgate 2, the tailgate 2 can drive the support rod 3 to move and compress the support rod 3. Since the distance between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle is 0, and the rotation plane of the tailgate 2 is perpendicular to the width direction of the vehicle, in the process of closing the tailgate 2, the support rod 3 only extends on the plane perpendicular to the width direction of the vehicle, that is, the movement trajectory of the support rod 3 is on the plane perpendicular to the width direction of the vehicle, so that the space occupied by the support rod 3 in the width direction of the vehicle is small when it moves, and the movement envelope of the support rod 3 is small, which reduces the limitation of the shape seam of the tailgate opening and closing system 100 and improves the freedom of vehicle design. In this way, the support rod 3 can be applied to tailgates 2 with various forms of opening and closing, for example, the tailgate 2 can be an ordinary hatchback door, or the tailgate 2 can be a gull-wing door.

[0048] For example, a body exterior shell 82 and a trunk interior shell 83 may be provided on both sides of the side beam 12. In the length direction of the vehicle, at least part of the body exterior shell 82 extends to the rear of the side beam 12, and at least part of the trunk interior shell 83 extends to the rear of the side beam 12. The body exterior shell 82, the trunk interior shell 83 and the side beam 12 jointly define a water flow groove 84, and the support rod 3 is arranged in the water flow groove 84. The spacing between the rotation center point of the door end 31 and the rotation center point of the frame end 32 in the width direction of the vehicle is set to 0-10cm, so that the interference of the support rod 3 on the body exterior shell 82 and the trunk interior shell 83 can be reduced, so that the water flow groove 84 is set smaller, and the opening of the trunk 81 is set larger, thereby improving the overall performance of the vehicle.

[0049] Reference Figure 1-Figure 3 According to some embodiments of the utility model, the support rod 3 is connected to the tailgate 2 through a ball joint structure, the ball joint structure includes a ball seat and a ball head, one of the ball seat and the ball head is connected to the door end 31, and the other of the ball seat and the ball head is connected to the tailgate 2; the ball joint structure connected to the tailgate 2 is a first ball joint structure 4.

[0050] For example, the first ball joint structure 4 may also include a first connection portion connected to the first ball head portion, and the first connection portion is detachably connected to the side beam 12, so that the first ball joint structure 4 has a sufficient length to be connected to the tailgate 2, thereby ensuring the reliability of the connection between the first ball joint structure 4 and the tailgate 2. Specifically, the first connection portion may be a screw.

[0051] In this way, a ball hinge connection can be achieved between the door end 31 and the door, so that the support rod 3 can rotate within a larger range, and the support rod 3 can move to a certain extent in the width direction of the vehicle, so that the assembly accuracy between the tailgate 2 and the top beam does not need to be set high, thereby reducing the difficulty of the assembly process between the tailgate 2 and the rear frame 1 and improving the production efficiency of the vehicle.

[0052] Reference Figure 1-Figure 3 According to some embodiments of the utility model, the frame end 32 is provided with a ball joint structure, the ball joint structure includes a ball seat and a ball head, one of the ball seat and the ball head is connected to the frame end 32, and the other of the ball seat and the ball head is used to connect to the rear frame 1, and the ball joint structure connected to the frame end 32 is a second ball joint structure 5.

[0053] For example, the second ball joint structure 5 may further include a second connection portion connected to the second ball head portion, and the second connection portion is detachably connected to the tailgate 2, so that the first ball joint structure 4 has a sufficient length to be connected to the tailgate 2, thereby ensuring the reliability of the connection between the first ball joint structure 4 and the tailgate 2. Specifically, the second connection portion may be a screw.

[0054] In this way, a ball hinge connection can be achieved between the door end 31 and the door, so that the support rod 3 can rotate within a larger range, and the support rod 3 can move to a certain extent in the width direction of the vehicle, so that the assembly accuracy between the tailgate 2 and the top beam does not need to be set high, thereby reducing the difficulty of the assembly process between the tailgate 2 and the rear frame 1 and improving the production efficiency of the vehicle.

[0055] Reference Figure 1-Figure 3According to some embodiments of the utility model, the rotation axis of the tailgate 2 rotating around the rear frame 1 is the hinge axis, the distance between the rotation center point of the door end 31 and the hinge axis is the first distance, the distance between the rotation center point of the frame end 32 and the hinge axis is the second distance, and the first distance is smaller than the second distance. That is, the door end 31 is arranged close to the hinge axis of the tailgate 2 and the top beam, so that when the tailgate 2 is opened and closed, the displacement amplitude of the door end 31 in the length direction of the vehicle can be small, so that the support rod 3 can be extended and retracted roughly in the height direction of the vehicle, so that the space occupied by the support rod 3 in the front and rear directions of the vehicle is small when the support rod 3 moves, and the movement envelope of the support rod 3 is further reduced.

[0056] Reference Figure 1-Figure 3 According to some embodiments of the present invention, the rotation axis of the tailgate 2 rotating around the rear frame 1 is the hinge axis, and the distance from the rotation center point of the door end 31 to the hinge axis is the first distance, which is greater than or equal to 5 cm and less than or equal to 30 cm. For example, the first distance can be 5 cm, 6 cm, 7 cm, 8 cm, 9 cm, 10 cm, 11 cm, 12 cm, 13 cm, 14 cm, 15 cm, 16 cm, 17 cm, 18 cm, 19 cm, 10 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 20 cm, 21 cm, 22 cm, 23 cm, 24 cm, 25 cm, 26 cm, 27 cm, 28 cm, 29 cm, 30 cm.

[0057] The smaller the value of the first distance is, the smaller the rotation range of the door end 31 is, the smaller the space occupied by the support rod 3 in the front and rear directions of the vehicle is when the support rod 3 moves, and the smaller the movement envelope of the support rod 3 is; the larger the value of the first distance is, the greater the torque applied by the support rod 3 to the tailgate 2 is, the better the support effect of the support rod 3 on the tailgate 2 is, and a support rod 3 with a smaller power can be selected, so that the cost of the support rod 3 is reduced. By setting the first distance to be greater than or equal to 5 cm and less than or equal to 30 cm, the compactness of the space occupied by the support rod 3 and the reliability of the support rod 3 supporting the tailgate 2 are taken into account, so that the production cost of the support rod 3 is low, thereby reducing the production cost of the vehicle.

[0058] Reference Figure 1-Figure 3 According to some optional embodiments of the utility model, the tailgate 2 includes an outer panel 21 and an inner panel 22, the outer panel 21 and the inner panel 22 define a wiring cavity 23, the door end 31 is rotatably connected to the inner panel 22, for example, the second ball hinge structure 5 is connected to the inner panel 22, and a wiring hole 221 is opened on the inner panel 22.

[0059] The support rod 3 includes a support rod body 33 and a drive pipeline 34. The support rod body 33 includes a frame end 32 and a door end 31. The drive pipeline 34 includes an input end 341 and an output end 342. The drive pipeline 34 passes through the wiring hole 221, and the output end 342 is connected to the door end 31. The output end 342 is located in the wiring cavity 23.

[0060] When the support rod 3 is an electric push rod, the drive pipeline 34 can be a power transmission harness, and the drive pipeline 34 is used to supply electricity to the support rod body 33. When the support rod 3 is a hydraulic push rod, the drive pipeline 34 can be a hydraulic pipe, and the drive pipeline 34 is used to deliver hydraulic medium to the support rod body 33, and the drive pipeline 34 is used to output the hydraulic medium in the support rod body 33; for example, the hydraulic medium can be hydraulic oil or water. When the support rod 3 is a pneumatic push rod, the drive pipeline 34 can be a pneumatic pipe, and the drive pipeline 34 is used to deliver pneumatic medium to the support rod body 33, and the drive pipeline 34 is used to output the pneumatic medium in the support rod body 33; for example, the pneumatic medium can be air or nitrogen.

[0061] By arranging the wiring hole 221 of the drive pipeline 34 on the tailgate 2 and arranging the drive pipeline 34 in the wiring cavity 23 of the tailgate 2, rainwater can be effectively prevented from flowing into the wiring hole 221 through the gap between the tailgate 2 and the rear frame 1, thereby ensuring the sealing effect of the wiring cavity 23 of the tailgate 2. Compared with the arrangement of the wiring hole 221 on the side beam 12, rainwater can be prevented from flowing into the vehicle body cavity from the wiring hole 221, thereby improving the overall sealing effect of the vehicle.

[0062] Reference Figure 1-Figure 3 In some optional embodiments of the utility model, the inner plate 22 is an annular plate with an internal opening, and the internal opening of the inner plate 22 forms an inspection port 222, which is connected to the wiring cavity 23, and the input end 341 is opposite to the inspection port 222 in the thickness direction of the tailgate 2. For example, the inspection port 222 is detachably connected to the tailgate trim 24. For example, the input end 341 of the drive pipeline 34 is provided with a plug terminal, and the wiring cavity 23 is provided with a plug connector connected to the drive source, and the plug terminal and the plug connector are detachably plugged together to provide power to the support rod body 33. When the support rod 3 is an electric push rod, the drive source can be a battery pack of the vehicle; when the support rod 3 is a hydraulic push rod, the drive source can be a hydraulic pump; when the support rod 3 is a starting push rod, the drive source can be a pneumatic pump. The plug connector is opposite to the inspection port 222. In this way, it is convenient to inspect the power supply system of the ring support rod 3 and reduce the difficulty of repairing the support rod 3.

[0063] Reference Figure 1-Figure 3In some optional embodiments of the present invention, the orthographic projection of the center point of the wiring hole 221 on the second projection plane is the first projection point, the orthographic projection of the rotation center point of the door end 31 on the second projection plane is the second projection point, the line between the first projection point and the second projection point is perpendicular to the first projection plane, and the second projection plane is perpendicular to the height direction of the vehicle. In other words, the distance between the center point of the wiring hole 221 and the rotation center point of the door end 31 in the width direction of the vehicle is 0. The wiring hole 221 is located on the side of the door end 31 close to the top beam.

[0064] When the tailgate 2 is opened, in the front-to-rear direction of the vehicle, the wiring hole 221 is located on the front side of the support rod body 33, and the drive pipeline 34 is located on the front side of the support rod body 33. The support rod body 33 can provide a certain shielding effect on the wiring hole 221 and the drive pipeline 34, so that the exposed part of the tailgate opening and closing system 100 is relatively simple and integrated, meeting the user's requirements for higher perceived quality.

[0065] Reference Figure 1-Figure 3 In some optional embodiments of the present invention, the tailgate opening and closing system 100 further includes: an adapter bracket 6, the adapter bracket 6 is connected to the inner plate 22, the connection point between the adapter bracket 6 and the inner plate 22 and the center point of the wiring hole 221 in the width direction of the vehicle, and the door end 31 is rotatably connected to the adapter bracket 6. In the process of opening and closing the tailgate 2, this can prevent the adapter bracket 6 from interfering with the drive pipeline 34, prevent the support rod body 33 from interfering with the drive pipeline 34, extend the service life of the support rod body 33 and the drive pipeline 34, improve the service life of the support rod 3, and improve the reliability of the support rod 3.

[0066] For example, refer to Figure 1-Figure 3 The adapter bracket 6 may include a first adapter plate 61 and a second adapter plate 62. The first adapter plate 61 is welded and fixed to the inner plate 22. The second adapter plate 62 is connected to one end of the first adapter plate 61 in the width direction of the vehicle. The first adapter plate 61 and the second adapter plate 62 are arranged in an L shape. The first ball joint structure 4 is connected to the second adapter plate 62. By welding and fixing the first adapter plate 61 to the inner plate 22, compared with the solution of setting a fastener to connect the adapter bracket 6 and the inner plate 22, interference between the fastener and the drive pipeline 34 can be prevented, and the reliability of the drive pipeline 34 can be further improved.

[0067] Specifically, refer to Figure 1-Figure 3 The second adapter plate 62 can be connected to the side of the first adapter plate 61 close to the opening of the trunk 81, so that the second adapter plate 62 can play a certain shielding role on the wiring hole 221 and the drive pipeline 34, making the exposed part of the tailgate opening and closing system 100 relatively simple and integrated, further meeting the user's requirements for higher perceived quality.

For example, the bellows 71 may be a plastic part, or a rubber part; when the bellows 71 is a plastic part, the bellows 71 may be a polyvinyl chloride part, a polyethylene part, or a polypropylene part. The bellows 71 may protect the drive pipeline 34 to a certain extent, prevent the support rod body 33 from interfering with the drive pipeline 34, prevent the side wall of the wiring hole 221 from interfering with the drive pipeline 34, extend the service life of the drive pipeline 34, increase the service life of the support rod 3, and improve the reliability of the support rod 3.
