DETAILED DESCRIPTION
[0018] The following will describe the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention, not for limiting the scope of protection of the present invention.
[0019] It should be noted that the illustrations provided in the following embodiments are only schematic illustrations of the basic concept of the present invention, and thus the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.
[0020] like Figure 1 and Figure 2 A swing-out door hinge shown in the figure includes a transmission arm 2, a first mounting member 1 for connecting to a vehicle body, and a second mounting member 3 for connecting to a vehicle door. The rear end of the transmission arm 2 is rotatably connected to the first mounting member 1 via a rotatable structure whose rotation axis extends in the up-down direction, and the front end of the transmission arm 2 is rotatably and slidably connected to the second mounting member 3 via a rotatable and sliding structure whose rotation axis extends in the up-down direction. When the swing-out door hinge is in a closed state, the sliding axis of the rotatable and sliding structure extends in the front-to-back direction.
[0021] When the above-mentioned swing-out door hinge is applied to a vehicle, when the door just starts to open, the transmission arm 2 rotates toward the outside of the vehicle, and the transmission arm 2 drives the second mounting member 3 and the door to swing out. Since the front end of the transmission arm 2 is rotatably and slidably connected to the second mounting member 3, when the door is a rear door of a vehicle, and the front of the rear door of the vehicle is blocked by the rear of the front door of the vehicle, the rear door of the vehicle can rotate around the rotatable and sliding structure during the process of the transmission arm 2 driving the second mounting member 3 and the rear door of the vehicle to swing out toward the outside of the vehicle. The rotation of the rear door of the vehicle around the rotatable and sliding structure can make the front of the rear door of the vehicle avoid the rear of the front door of the vehicle. The use of the above-mentioned swing-out door hinge can meet the use requirements of the rear door of the vehicle, and has the characteristics of being easy to implement and simple in structure.
[0022] It should be noted that the swing-out door hinge has an open state and a closed state. When the door connected to the swing-out door hinge is in the open state, the swing-out door hinge is in the open state. When the door connected to the swing-out door hinge is in the closed state, the swing-out door hinge is in the closed state.
[0023] In some embodiments, the rotatable and sliding structure includes a first pin shaft 4 and a strip hole 302, the first pin shaft 4 and the strip hole 302 are rotatably and slidably connected, the first pin shaft 4 is connected to one of the transmission arm 2 and the second mounting member 3, and the strip hole 302 is provided on the other of the transmission arm 2 and the second mounting member 3. As a preferred solution, the strip hole 302 is provided on the second mounting member 3, and the first pin shaft 4 is connected to the transmission arm 2. The rotatable and sliding connection between the front end of the transmission arm 2 and the second mounting member 3 is realized by using the first pin shaft 4 and the strip hole 302, which has the characteristic of being easy to realize.
[0024] In a specific implementation, in order to ensure that the rear door of the vehicle can rotate better during the opening process, when the swing-out door hinge is in a closed state, there is a gap between the first pin shaft 4 and the rear end wall of the strip hole 302, and the gap is set so that the first pin shaft 4 can slide backward relative to the strip hole 302. The gap between the first pin shaft 4 and the rear end wall of the strip hole 302 can be determined according to the amount of the rear door of the vehicle being blocked by the front door of the vehicle. When the rear door of the vehicle just starts to open, the transmission arm 2 rotates toward the outside of the vehicle, and the first pin shaft 4 rotates and slides relative to the strip hole 302, so that the rear door of the vehicle can rotate and swing more smoothly, so that the rear door of the vehicle can be swung out more smoothly.
