[0031] The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention.

[0032] First, refer to Figure 1 as well as Figure 2 As shown, the present invention provides an outward opening device, comprising an outward opening handle 1, a connecting rod assembly 2, a cable connection 3, an elastic member 4 and an outward opening cable 5, wherein:

[0033] The outward opening handle 1 can move along a first direction D1. The connecting rod assembly 2 is connected to the outward opening handle 1. The first direction D1 is counterclockwise. When the outward opening handle 1 is rotated counterclockwise, the connecting rod assembly 2 moves synchronously along a first preset path with the movement of the outward opening handle 1.

[0034] The cable connector 3 is connected to the connecting rod assembly 2, and the cable connector 3 can move along a second preset path. The second preset path includes a first stroke and a second stroke, and the first stroke and the second stroke are connected. When the connecting rod assembly 2 starts to move along the first preset path, the cable connector 3 moves in the first stroke at the same time.

[0035] The elastic member 4 is connected to the cable connector 3. During the movement of the cable connector 3 in the first stroke and the second stroke, the elastic member 4 is elastically deformed by the cable connector 3, accumulating elastic force, and applying the elastic force to the cable connector 3, so that the cable connector 3 has a tendency to return to the starting end of the second preset path.

[0036] One end of the outer opening cable 5 is connected to the vehicle door lock, and the other end of the outer opening cable 5 is connected to the cable connector 3. When the cable connector 3 moves to the end of the second stroke, the vehicle door lock can be unlocked.

[0037] In the embodiment provided by the present application, when the external opening handle 1 moves along the first direction (counterclockwise), it can drive the connecting rod assembly 2 to move along the first preset path, and then drive the cable connector 3 to move in the first stroke. During the movement of the cable connector 3 in the first stroke, the external opening cable 5 is not pulled, and the cable connector 3 is only affected by the elastic force of the elastic part 4. The cable connector 3 transmits the elastic force to the connecting rod assembly 2, and then the connecting rod assembly 2 is also only affected by the elastic force of the elastic part 4.

[0038] When the cable connector 3 moves in the second stroke, the external opening cable 5 is pulled, and then when the external opening handle 1 is pulled, the elastic force of the elastic member 4 and the force of the external opening cable 5 must be overcome at the same time to unlock the car door lock. When the cable connector 3 moves to the end of the second stroke, the car door lock is unlocked and the car door can be opened.

[0039] When the vehicle door is closed, the outer opening handle 1 is released, and the cable connector 3 is reset under the elastic force exerted by the elastic member 4, thereby driving the connecting rod assembly 2 and the outer opening handle 1 to reset.

[0040] Compared with the existing technology, when the outward opening handle 1 is rotated, the elastic force of the two return springs and the force of the outward opening cable 5 need to be overcome to open the car door. In the process of opening the car door, the outward opening device of the present application only needs to overcome the elastic force exerted by the elastic member 4 during the first stroke movement, thereby reducing the opening force required to open the car door and improving the comfort of opening the car door.

[0041] In addition, the reset of the external opening handle 1 and the connecting rod assembly 2 can be achieved by only one elastic part 4, which reduces the number of elastic parts 4 and is conducive to reducing costs; during the opening process of the external opening handle 1, no reset spring is exposed, which can effectively improve the perceived quality; the originally hollow area of the connecting rod assembly 2 can be completely sealed, which can reduce the entry of moisture, dust and wind dust, and thus help improve the sound quality of the vehicle.

[0042] In a feasible embodiment, the elastic member 4 is a torsion spring, one end of which is connected to the cable connector 3, and the other end of which is connected to the vehicle body. When the cable connector 3 moves in the first stroke, the torsion spring rotates under the action of the cable connector 3, and accumulates elastic force as the cable connector 3 continues to move, and applies the accumulated elastic force to the cable connector 3, so that the cable connector 3 has a tendency to return to the starting end of the second preset path. When the outward opening handle is released, the elastic force accumulated by the elastic member 4 can drive the cable connector 3 to move toward the starting end of the second preset path. At the same time, because the cable connector 3 can transmit the elastic force to the connecting rod assembly 2, the connecting rod assembly 2 then moves synchronously toward the starting end of the first preset path, thereby resetting the connecting rod assembly 2 and the cable connector 3.

[0043] Furthermore, the second preset path is the rotational movement path of the cable connector 3 along the first direction D1, that is, when the outward opening handle 1 is pulled counterclockwise, the cable connector 3 rotates synchronously in the counterclockwise direction, and a force is applied to the torsion spring during the rotation, causing the torsion spring to rotate and undergo elastic deformation.

[0044] Reference Figure 3 As shown, the first stroke is the rotational movement path of the cable connector 3 along the first direction D1 when the torsion spring rotates through the first preset angle. In the figure, the cable connector 3 is located on the left side, which is the initial position of the first stroke. Preferably, the first preset angle is 0-30°. That is, when the torsion spring rotates through 0-30°, the cable connector 3 is within the first stroke. During this stage, the torsion spring only provides a restoring force for the connecting rod assembly 2.

[0045] Continue to refer to Figure 3 As shown, the second stroke is the rotational movement path of the cable connector 3 along the first direction D1 when the torsion spring rotates by the second preset angle. In the figure, the cable connector 3 is located on the right side, which is the end of the second stroke. Preferably, the second preset angle is 30-75 degrees. As the cable connector 3 continues to move, when the torsion spring rotation angle exceeds 30 degrees, the cable connector 3 moves to the second stroke stage. At this stage, the external opening cable 5 is pulled, and the force required to pull the external opening handle 1 is increased to unlock the vehicle door lock. When the torsion spring rotation angle reaches 75 degrees, the cable connector 3 moves to the end of the second stroke, unlocking the vehicle door lock. At this stage, the torsion spring provides a reset force to the external opening handle 1.

[0046] During the movement of the cable connector 3, the torsion spring can provide appropriate reset force in different movement stages in a segmented force distribution manner, so that the torsion spring can provide different reset forces in different angle ranges, better adapting to the movement characteristics of the outward-opening handle 1.

[0047] When the outward opening handle 1 in the prior art is reset, the reset angle of the torsion spring is 45°, while the reset angle of the torsion spring in the present application is increased to 75°, so that the outward opening handle 1 has a larger angle range for reset, that is, when opening the car door, the outward opening handle 1 has a larger angle range to pull, thereby improving the comfort of opening the car door.

[0048] Reference Figure 4 as well as Figure 5 As shown, the outward opening device includes a pin shaft 6, one end of the pin shaft 6 is connected to the connecting rod assembly 2, and the other end of the pin shaft 6 is connected to the cable connector 3. When the outward opening handle 1 moves along the first direction D1 to drive the connecting rod assembly 2 to move along the first preset path, the pin shaft 6 rotates synchronously with the movement of the connecting rod assembly 2, thereby driving the cable connector 3 to move along the second preset path.

[0049] Reference Figure 6 As shown, the outward opening device also includes a handle base 7, the outward opening handle 1 is arranged on the handle base 7, the connecting rod assembly 2 includes a first connecting rod 21, a second connecting rod 22 and a third connecting rod 23, one end of the first connecting rod 21 is hinged to the handle base 7, one end of the second connecting rod 22 is hinged to the first connecting rod 21, one end of the third connecting rod 23 is hinged to the handle base 7, and the other end of the third connecting rod 23 is hinged to the second connecting rod 22 and connected to the cable connector 3.

[0050] The handle base 7, the first connecting rod 21, the second connecting rod 22, and the third connecting rod 23 form a four-bar linkage structure. Based on the characteristics of the four-bar linkage structure, a linkage relationship is formed between the outside opening handle 1 and the connecting rod assembly 2. The handle base 7 is located inside the vehicle body. The second direction D2 is the direction of movement of the handle base 7 extending from the surface of the vehicle body. When opening the vehicle door, the handle base 7 must first be extended from the vehicle body, exposing the outside opening handle 1 to the outside, thereby facilitating rotation of the outside opening handle 1.

[0051] Furthermore, the outward opening device includes a driving member 8, which is used to drive the connecting rod assembly 2 to move along the first direction D1, so that the handle base 7 moves along the second direction D2. The handle base 7 is arranged inside the vehicle body, and the second direction D2 is the movement direction of the handle base 7 extending out of the vehicle body surface. Since there is a linkage relationship between the outward opening handle 1 and the connecting rod assembly 2, when the vehicle door is opened, the driving member 8 is used to drive the connecting rod assembly 2 to move along the first direction D1, driving the handle base 7 to move along the second direction D2, so that the handle base 7 is extended from the vehicle body, and then the outward opening handle 1 is exposed to the outside, which is convenient for rotating the outward opening handle 1.

[0052] Specifically, the driving member 8 includes an actuator 81, and a driving block 9 is provided on the first connecting rod 21. When the actuator 81 abuts against the driving block 9, it can drive the first connecting rod 21 to rotate counterclockwise. The actuator 81 continuously abuts against the driving block 9, which can enable the first connecting rod 21 to continue to rotate. The second connecting rod 22 and the third connecting rod 23 move adaptively with the rotation of the first connecting rod 21 to drive the handle base 7 to pop out from the surface of the vehicle body.

[0053] Based on the above embodiments, the process of opening the car door by the outward-opening device of the present invention is as follows: the actuator 81 starts to counteract the drive block 9 and continues to act on the drive block 9, causing the first connecting rod 21 to rotate counterclockwise, driving the second connecting rod 22 and the third connecting rod 23 to move adaptively, pushing the handle base 7 out of the vehicle body, thereby exposing the outward-opening handle 1.

[0054] Rotate the external opening handle 1 so that the external opening handle 1 moves along the first direction D1 (counterclockwise), driving the third connecting rod 23 to move along the first direction D1 (first preset path), thereby driving the cable connector 3 to rotate within the first stroke. During this stroke, the external opening cable 5 is not pulled. When the cable connector 3 rotates in the second stroke, the external opening cable 5 is pulled. When the cable connector 3 moves to the end of the second stroke, the door lock is unlocked. During the movement of the cable connector 3 along the second preset path, the elastic member 4 continues to accumulate elastic force and applies the elastic force to the cable connector 3, so that the cable connector 3 has a tendency to return to the second preset path.

[0055] When closing the car door, release the external opening handle 1, and the cable connector 3 moves to the starting end of the second preset path under the elastic force applied by the elastic member 4, and the connecting rod assembly 2 then returns to the starting end of the first preset path, thereby resetting the external opening handle 1.

[0056] In a second aspect, the present invention provides a vehicle including the aforementioned outward opening device. Since the outward opening device of the present invention requires only a small opening force to open the vehicle door, it provides better comfort and helps reduce vehicle manufacturing costs.

[0057] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings. The above is only a preferred embodiment of the present invention, but the scope of implementation of the present invention is not limited to what is shown in the drawings. Any changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which do not exceed the spirit covered by the description and drawings, should be within the scope of protection of the present invention.
