Abstract

This utility model relates to the technical field of vehicle production and manufacturing, specifically to a vehicle door device and a vehicle. A sliding portion of a first swing arm is slidably mounted on a guide rail, and a first swing portion of the first swing arm is rotatably connected to a handle. When the push rod assembly moves in a first direction, it pushes the sliding portion to move along the guide rail, pushing the handle to move away from the housing. A second swing arm is rotatably connected to both the handle and the housing. The push rod assembly abuts against the side of the second swing arm away from the handle. When the push rod assembly moves in the first direction, it pushes the second swing arm, which in turn pushes the handle to move away from the housing. The interaction between the push rod assembly and the swing arm assembly pushes the handle to expose it outside the housing, enabling the door to be opened. Simultaneously, the handle can also be hidden inside the housing in the opposite direction, reducing the drag coefficient of the door device and thus reducing vehicle fuel consumption.

[0029] Most existing vehicles use exposed door handles, but traditional exposed handles disrupt airflow on the vehicle body surface, increase the drag coefficient, and negatively impact the range of electric vehicles or the fuel consumption of gasoline vehicles.

[0030] To solve the above technical problems, refer to Figures 1 to 3 As shown, this application provides a car door device, including a housing 10, a handle 20, a swing arm assembly 30, and a push rod assembly 40. The handle 20 is hidden inside the door or exposed outside the door through the mutual cooperation of the push rod assembly 40 and the swing arm assembly 30.

[0031] In some embodiments, the housing 10 forms a guide rail 11; the handle 20 extends along a first direction X1; the swing arm assembly 30 includes a first swing arm 31 and a second swing arm 32, the first swing arm 31 includes a sliding portion 311 and a first swing portion 312, the sliding portion 311 is slidably disposed on the guide rail 11, and the first swing portion 312 is rotatably connected to the handle 20; the second swing arm 32 is rotatably connected to the handle 20 and the housing 10 respectively; the push rod assembly 40 is located on the same side of the handle 20 as the swing arm assembly 30, and is used to slide in the first direction X1, the push rod assembly 40 abuts against the sliding portion 311 and the side of the second swing arm 32 away from the handle 20, so that the handle 20 moves closer to or away from the housing 10. Thus, the sliding part 311 of the first swing arm 31 is slidably disposed on the guide rail 11, and the first swing part 312 of the first swing arm 31 is rotatably connected to the handle 20. When the push rod assembly 40 moves in the first direction X1, it pushes the sliding part 311 to move in the guide rail 11, and the first swing part 312 swings under the action of the sliding part 311. The first swing part 312 rotates relative to the handle 20 and pushes the handle 20 to move away from the housing 10. The second swing arm 32 is rotatably connected to the handle 20 and the housing 10 respectively. The push rod assembly 40 abuts against the side of the second swing arm 32 away from the handle 20. When the push rod assembly 40 moves in the first direction X1, it pushes the side of the second swing arm 32 away from the handle 20, causing the second swing arm 32 to rotate relative to the housing 10. The side of the second swing arm 32 close to the handle 20 swings and the second swing arm 32 rotates relative to the handle 20. The second swing arm 32 pushes the handle 20 to move away from the housing 10. The handle 20 is pushed out of the housing 10 by the cooperation of the push rod assembly 40 and the swing arm assembly 30, so that the handle 20 can be opened. At the same time, it can also move in the opposite direction to hide the handle 20 inside the housing 10, reducing the wind resistance coefficient of the door device and thus reducing vehicle fuel consumption.

[0032] In some embodiments, refer to Figure 1 As shown, the door device in this application can also make the body lines smoother and the outer surface of the door flatter through the design of the hidden handle 20. In low-speed collision accidents, the hidden handle 20 can reduce additional injuries to pedestrians, and in daily use, the hidden handle 20 can be linked with the vehicle to form a better anti-theft function.

[0033] In some embodiments, refer to Figure 1 As shown, the first direction X1 is the front-to-back direction of the vehicle, and the second direction X2 is the left-to-right direction of the vehicle. The first direction X1 and the second direction X2 are perpendicular. The length direction of the handle 20 is along the first direction X1, and the direction in which the handle 20 approaches and moves away from the housing 10 is along the second direction X2. That is, the handle 20 moves along the left-to-right direction of the door assembly.

[0034] In some embodiments, refer to Figure 1As shown, the housing 10 forms a receiving cavity 12, and the receiving cavity 12 of the housing 10 has at least a slot facing outwards from the door assembly. When the handle 20 is hidden inside the door assembly, the handle 20 is close to the housing 10 and located in the receiving cavity 12, and the plane of the handle 20 facing outwards from the door assembly, the plane of the housing 10 facing outwards from the door assembly, and the plane of the door body facing outwards from the door assembly are flush. At this time, the handle 20 is in a hidden state. (Refer to...) Figure 2 As shown, when the vehicle is parked, a command can be issued via the vehicle's infotainment system or button operation to expose the handle 20 outside the door assembly; at this time, the handle 20 is in the extended position. (Refer to...) Figure 3 As shown, when the handle 20 is exposed outside the door assembly, the handle 20 is away from the housing 10 and located outside the receiving cavity 12. The door assembly can be opened by pulling the handle 20, thus putting the handle 20 in the unlocked state. When the door is in motion, a command can be issued through the vehicle system or button operation to hide the handle 20 inside the door assembly.

[0035] In some embodiments, refer to Figure 1 As shown, the sliding part 311 and the first swing part 312, the first swing part 312 and the handle 20, the second swing arm 32 and the handle 20, and the second swing arm 32 and the housing 10 are all connected by rotating shafts to realize the relative rotation of the sliding part 311 and the first swing part 312, the relative rotation of the first swing part 312 and the handle 20, the relative rotation of the second swing arm 32 and the handle 20, and the relative rotation of the second swing arm 32 and the housing 10.

[0036] In some embodiments, refer to Figures 1 to 3 As shown, the guide rail 11 is an arc-shaped rail, protruding from the side opposite to the handle 20. After the sliding part 311 moves a certain displacement in the guide rail 11, it can drive the first swing part 312 to push the handle 20. At this time, the guide rail 11 can be set long enough. When the sliding part 311 is located at the end of the guide rail 11 facing the push rod assembly 40, the handle 20 is hidden inside the housing 10. When the sliding part 311 is located in the middle of the guide rail 11, the handle 20 is exposed outside the housing 10. When the handle 20 is in the exposed state, applying a pulling force to the handle 20 will cause the sliding part 311 to move continuously in the guide rail 11, and unlocking will be achieved by connecting the first swing arm 31 to the unlocking assembly 80 outside the housing 10.

[0037] In some embodiments, refer to Figure 3 As shown, the housing 10 forms a groove 13 along the first direction X1, and the push rod assembly 40 forms a slide rail 43 on the side facing the sidewall, with the slide rail 43 disposed in the groove 13. The cooperation between the groove 13 and the slide rail 43 allows the push rod assembly 40 to slide in the first direction X1.

[0038] In some embodiments, refer to Figures 1 to 4As shown, the guide rail 11 forms a first opening 111 on the side facing the first swing part 312; the door device also includes a hook part 50, one side of which is rotatably connected to the housing 10, and the other side of which forms a second opening 51, which communicates with the first opening 111. The push rod assembly 40 pushes the sliding part 311 along the first direction X1 to move it through the first opening 111 into the second opening 51. The side of the guide rail 11 opposite to the first opening 111 is closed. The sliding part 311 moves between the guide rail 11 and the hook part 50 through the docking of the first opening 111 and the second opening 51. Continuously pushing the sliding part 311 allows it to swing through the hook part 50, thereby allowing the handle 20 to continue moving in the direction of the guide rail 11. When the handle 20 is in the flat position, applying a pulling force to the handle 20 causes the first swing arm 31 to continuously rotate the hook part 50, which can unlock the housing 10 by driving the unlocking assembly 80 outside the housing 10 through the hook part 50. Specifically, in combination with Figure 1 As shown, when the sliding part 311 is located in the first opening 111, the handle 20 is hidden inside the housing 10; combined with Figure 2 As shown, when the sliding part 311 is located at the second opening 51 and the hook part 50 abuts against the guide rail 11, the handle 20 is in a flat-out state outside the housing 10; combined Figure 3 As shown, when the sliding part 311 is located in the second opening 51 and the hook part 50 is away from the guide rail 11, the handle 20 is located outside the housing 10 and is in the unlocked state.

[0039] In some embodiments, refer to Figure 4 As shown, the door assembly includes a first pivot 60 that passes through a sliding portion 311. The first pivot 60 protrudes from both sides of the sliding portion 311 to form protrusions 61, which are located within the guide rail 11 or the second opening 51. The first pivot 60 is rotatably connected to the sliding portion 311. When the push rod assembly 40 pushes the sliding portion 311 in a first direction X1, the protrusions of the first pivot 60 move within the guide rail 11 and the second opening 51. Specifically, in conjunction with... Figure 1 As shown, when the protrusion 61 is located at the first opening 111, the handle 20 is hidden inside the housing 10; combined with Figure 2 As shown, when the protrusion 61 is located at the second opening 51 and the hook 50 abuts against the guide rail 11, the handle 20 is in a flat-out state outside the housing 10; combined with Figure 3 As shown, when the protrusion 61 is located at the second opening 51 and the hook 50 is away from the guide rail 11, the handle 20 is located outside the housing 10 and is in the unlocked state.

[0040] In some embodiments, combined with Figure 3 and Figure 4As shown, the handle 20 is connected to the housing 10 via a first swing arm 31 and a second swing arm 32. The housing 10 is installed inside the door of the door device. The handle 20 also needs to be connected to the unlocking assembly 80 of the door device to achieve unlocking and locking functions. The length direction of the handle 20 extends along the front-rear direction of the vehicle, which is the first direction X1.

[0041] In some embodiments, combined with Figure 3 and Figure 4 As shown, the housing 10 forms a receiving cavity 12; the door device also includes a second rotating shaft 70, which passes through the side wall of the receiving cavity 12. Within the receiving cavity 12, the second rotating shaft 70 is rotatably connected to the hook portion 50. The door device also includes an unlocking assembly 80, which is located outside the receiving cavity 12 and connected to the second rotating shaft 70. The hook portion 50 has a shaft hole corresponding to the second rotating shaft 70, and the inner wall of the shaft hole forms a keyway. The outer wall of the second rotating shaft 70 forms a key located within the keyway. There is a free travel between the key and the keyway. This free travel does not cause the second rotating shaft 70 to rotate during the transition of the handle 20 from a hidden state to a flat position, and consequently, it does not cause the unlocking assembly 80 to rotate, thus maintaining the locked state of the door device. When the handle 20 is switched from the flat position to the unlocked position, the keyway abuts against the protrusion in the clockwise direction. Continuing to pull the handle 20 drives the second rotating shaft 70 to rotate through the first swing arm 31 and the hook part 50, thereby driving the unlocking component 80 to rotate and achieve unlocking.

[0042] In some embodiments, combined with Figure 3 and Figure 4 As shown, the accommodating cavity 12 is used to house the handle 20, the swing arm assembly 30, and the push rod assembly 40. The unlocking assembly 80 is outside the housing 10 and is located between the sheet metal layers of the door assembly. The unlocking assembly 80 includes a cam 81, a latch, etc. The cam 81 is shown in the figure. The cam 81 and the latch can be connected by a rope. The handle 20 is exposed outside the housing 10 in both a flat-out state and an unlocked state. When the handle 20 is in the flat-out state, a pulling force needs to be applied outside the door assembly to pull the handle 20 to the unlocked state. Specifically, after the handle 20 is flat-out, the gap area between the first swing arm 31 and the second swing arm 32 is also exposed outside the door housing 10, thus creating a force-bearing space. Applying a pulling force to the force-bearing space pulls the handle 20 to make it rotate around the pivot. The hook part 50 and the first swing arm 31 continue to rotate clockwise, thereby driving the cam 81 to rotate clockwise through the pivot, driving the rope to pull the latch to unlock.

[0043] In some embodiments, refer to Figure 3 and Figure 4As shown, the second swing arm 32 includes a second rotating part 321, a second swinging part 322, and an abutting part 323. The second rotating part 321 is rotatably connected to the housing 10, the second swinging part 322 is rotatably connected to the handle 20, and the abutting part 323 is disposed between the second rotating part 321 and the second swinging part 322. The push rod assembly 40 abuts against the abutting part 323. The push rod assembly 40 forms a hole extending along the first direction X1. The abutting part 323 protrudes from the second swing arm 32 towards the side opposite to the handle 20 and is located in the hole, abutting against the side wall of the hole. The hole of the push rod assembly 40 can accommodate part of the second swing arm 32. When the push rod assembly 40 moves, the hole wall can apply a pushing force to the abutment part 323 to make the second swing arm 32 swing. The second swing arm 32 is a horizontal swing arm. The height of the second rotating part 321 and the second swinging part 322 are both higher than the height of the abutment part 323, so that the abutment part 323 can be inserted into the hole.

[0044] In some embodiments, refer to Figure 4 As shown, the door assembly also includes a second elastic element 92, which is a torsion spring. The second elastic element 92 is disposed on the pivot between the sliding part 311 and the first swing part 312, the pivot between the first swing part 312 and the handle 20, the pivot between the second swing arm 32 and the handle 20, and the pivot between the second swing arm 32 and the housing 10. When the handle 20 switches from the flat state to the hidden state, it can provide torque in the radial direction of the pivot, so that the first swing arm 31 and the second swing arm 32 of the handle 20 remain in contact with the push rod assembly 40, thereby facilitating the hiding of the handle 20 in the receiving cavity 12.

[0045] In some embodiments, refer to Figure 5 As shown, the push rod assembly 40 includes a pusher 41, a connecting rod 42, and a power device. The pusher 41 is slidably connected to the housing 10. One side of the connecting rod 42 is connected to the pusher 41, and the other side is used to connect to the power device. The power device can be a drive motor, which drives the connecting rod 42 to push the pusher 41 to reciprocate in a first direction X1. Figure 2As shown, when the pusher 41 moves from right to left in the first direction X1, it pushes the first swing arm 31 and the second swing arm 32 to swing clockwise, making the handle 20 exposed outside the door assembly. When the pusher 41 moves from left to right in the first direction X1, it provides a rebound space for the first swing arm 31 and the second swing arm 32. Under the elastic force of the second elastic member 92, the first swing arm 31 and the second swing arm 32 swing counterclockwise, thus hiding the handle 20 inside the door assembly. During the process of the handle 20 being exposed, the pusher 41 can push the swing arm assembly 30, and when the handle 20 is hidden, the pusher 41 can limit the movement of the swing arm assembly 30, preventing the handle 20 from being excessively hidden and causing unevenness on the outer surface of the door assembly.

[0046] In some embodiments, refer to Figure 5 As shown, the door assembly also includes a first elastic member 91. One side of the first elastic member 91 is connected to the first swing arm 31, and the other side of the first elastic member 91 is connected to the push rod assembly 40. The first elastic member 91 is connected between the sliding part 311 of the first swing arm 31 and the push rod assembly 40. The sliding part 311 is slidably disposed in the guide rail 11. When the push member 41 moves from left to right in the first direction X1, it pulls the first swing arm 31 and can maintain the sliding part 311 in contact with the push rod assembly 40. During the vehicle's operation, this prevents the sliding part 311 from colliding with the push rod assembly 40 and generating noise.

[0047] In this application, when the vehicle is parked, a command can be issued via vehicle-mounted system or button operation to expose the handle 20 outside the door device, at which time the handle 20 is in a horizontal position; when the door is in motion, a command can be issued via vehicle-mounted system or button operation to hide the handle 20 inside the door device, at which time the handle 20 is in a hidden position. The sliding part 311 of the first swing arm 31 is slidably disposed on the guide rail 11, and the first swing part 312 of the first swing arm 31 is rotatably connected to the handle 20; when the push rod assembly 40 moves in the first direction X1, it pushes the sliding part 311 to move in the guide rail 11, and the first swing part 312 swings under the action of the sliding part 311, the first swing part 312 rotates relative to the handle 20 and pushes the handle 20 to move away from the housing 10. The second swing arm 32 is rotatably connected to both the handle 20 and the housing 10. The push rod assembly 40 abuts against the side of the second swing arm 32 away from the handle 20. When the push rod assembly 40 moves in the first direction X1, it pushes the side of the second swing arm 32 away from the handle 20, causing the second swing arm 32 to rotate relative to the housing 10. The side of the second swing arm 32 closest to the handle 20 swings and rotates relative to the handle 20, pushing the handle 20 to move away from the housing 10. Through the cooperation of the push rod assembly 40 and the swing arm assembly 30, the handle 20 is exposed outside the housing 10, allowing the door to be opened. Simultaneously, it can also reverse its movement to hide the handle 20 inside the housing 10, reducing the drag coefficient of the door assembly and thus reducing vehicle fuel consumption.

[0048] This application also provides a vehicle, including a door assembly.
