DETAILED DESCRIPTION

[0061] The specific implementation of the present disclosure is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described herein is only used to illustrate and explain the present disclosure, and is not used to limit the present disclosure.

[0062] In the present disclosure, unless otherwise stated, the directions or positional relationships indicated by the directional words such as "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "inside", "outside", etc. are based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present disclosure. For example, the up, down, left, right, front, and rear directions may be consistent with the up, down, left, right, front, and rear directions of the vehicle. The Z direction may be consistent with the direction toward the top in the up-down direction (i.e., the height direction) of the vehicle, the X direction may be consistent with the direction toward the front in the front-to-back direction (i.e., the length direction, also the longitudinal direction) of the vehicle, and the Y direction may be consistent with the direction away from the longitudinal center plane in the left-right direction (i.e., the width direction, also the lateral direction) of the vehicle. For details, please refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The coordinate direction in .

[0063] Furthermore, in the present disclosure, the terms “first”, “second”, etc. are merely used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0064] In addition, in the present disclosure, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be directly connected or indirectly connected through an intermediate medium. For ordinary technicians in this field, the specific meanings of the above terms in the present disclosure can be understood according to specific circumstances.

[0065] For the scissor door, a hinge structure is used to connect with the vehicle body so that the door can swing laterally (i.e., Y direction, the width direction of the vehicle) and in the up and down direction (i.e., Z direction, the height direction of the vehicle) so that the door can be opened laterally outward (i.e., Y direction outward) and upward (i.e., Z direction upward) by moving it laterally inward (i.e., Y direction inward) and downward (i.e., Z direction downward) by moving it laterally inward (i.e., Y direction inward) and downward (i.e., Z direction downward) by closing it.

[0066] like Figures 1 to 5 As shown, the present disclosure provides a hinge device 100, which includes a mounting base 10, a first rotating block 20, a second rotating block 30, a first connecting arm 40, a second connecting arm 50, a third connecting arm 61 and a swing arm 60. The mounting base 10 is used to be mounted on a vehicle body, for example, mounted (such as screwed) on the side wall of the vehicle body, the first rotating block 20 is rotatably connected to the mounting base 10 around a first rotating axis 101, the second rotating block 30 is rotatably connected to the mounting base 10 around a second rotating axis 102, the third connecting arm 61 is connected to the swing arm 60, and one end of the third connecting arm 61 is connected to the third connecting arm 61. A rotating block 20 is rotatably connected, the other end of the third connecting arm 61 is rotatably connected to the first connecting arm 40, the other end of the first connecting arm 40 is rotatably connected to one end of the second connecting arm 50, and the other end of the second connecting arm 50 is rotatably connected to the second rotating block 30, wherein the swing arm 60 is used to be connected (such as screwed) to a vehicle door (such as a scissor-type vehicle door), so that by reasonably installing the hinge device, the swing arm 60 can be swung in the Y direction (the width direction of the vehicle) and the Z direction (the height direction of the vehicle), so that the vehicle door can swing in the Y direction and the Z direction, thereby realizing the opening and closing of the vehicle door.

[0067] During installation, the front end of the door (such as a scissor door or other special-shaped door) can be hinged to the vehicle body through the hinge device 100. When the swing arm 60 swings outward along the Y direction and upward along the Z direction, the rear end of the door can swing outward along the Y direction and upward along the Z direction around the hinge device 100, thereby realizing the opening of the door. When the door needs to be closed, the swing arm 60 can be swung inward along the Y direction and downward along the Z direction, thereby realizing the closing of the door.

[0068] In the hinge device 100 provided in the present invention, the mounting base 10, the first rotating block 20, the second rotating block 30, the first connecting arm 40, the second connecting arm 50 and the swing arm 60 are constructed as a multi-bar mechanism structure. Specifically, it can be constructed as a structure similar to a six-bar mechanism. When applied to a vehicle, the smooth opening and closing of the door (such as a scissor-type door) can be achieved.

[0069] In addition, the study found that in related technologies, the hinge structure used for scissor doors usually adopts a spatial four-bar linkage and its derivatives, requiring the rotation axes of each link to intersect at one point, resulting in high machining and assembly accuracy of the hinge structure, and the machining process and assembly are difficult to control.

[0070] Compared with the existing spatial four-bar linkage with high assembly precision, the hinge device 100 disclosed in the present invention may not require that the multiple rotation axes of the hinge device 100 be compared to one point, thus helping to reduce the processing precision and assembly difficulty.

[0071] It is understood that in the present disclosure, the third connecting arm 61 can be integrally formed on the swing arm 60, in which case the third connecting arm 61 can be the first part of the swing arm 60, or the third connecting arm 61 and the swing arm 60 can be processed separately, and the third connecting arm 61 is connected to the swing arm 60 by, for example, welding. In addition, it is understood that the vehicle door of the present disclosure can be a special-shaped vehicle door such as a scissor door, and can also be other special-shaped vehicle doors suitable for opening and closing with the hinge device provided by the present disclosure, and the present disclosure does not limit this.

[0072] In the present disclosure, the hinge device 100 can be constructed as a multi-axis single-degree-of-freedom mechanism, that is, the motion trajectory of each movable component in the hinge device 100 is certain, for example, the motion trajectory of the swing arm 60 connected to the door is certain, so that the motion trajectory of the door opening and closing is certain. Therefore, setting the hinge device 100 as a multi-axis single-degree-of-freedom mechanism is conducive to improving the stability of the motion of each moving component in the hinge device 100, thereby helping to improve the stability of the movement of the door during opening and closing.

[0073] There are many ways to achieve rotatable connection between the above-mentioned components of the hinge device, such as Figure 1 and Figure 2As shown, a revolute pair is used to connect the mounting base 10 and the first rotating block 20, the first rotating block 20 and the third connecting arm 61, the third connecting arm 61 and the first connecting arm 40, the first connecting arm 40 and the second connecting arm 50, the second connecting arm 50 and the second rotating block 30, or the second rotating block 30 and the mounting base 10. That is, the mounting base 10 and the first rotating block 20 can be connected by a revolute pair, the first rotating block 20 and the third connecting arm 61 can be connected by a revolute pair, the third connecting arm 61 and the first connecting arm 40 can be connected by a revolute pair, the first connecting arm 40 and the second connecting arm 50 can be connected by a revolute pair, the second connecting arm 50 and the second rotating block 30 can be connected by a revolute pair, and the second rotating block 30 and the mounting base 10 can be connected by a revolute pair. The revolute pair connection can achieve surface-to-surface contact, thereby improving the reliability of two components that rotate relative to each other.

[0074] like Figure 2 and Figure 3 As shown, in one embodiment of the present disclosure, the first rotation axis 101 is symmetrically arranged with the second rotation axis 102. The fact that the first rotation axis 101 can be symmetrically arranged with the second rotation axis 102 is conducive to designing the motion trajectory of the first rotating block 20 and the second rotating block 30, thereby simplifying the motion trajectory of the hinge device. In addition, since the first rotation axis 101 can be symmetrically arranged with the second rotation axis 102, during the rotation process, the first rotating block 20 and the second rotating block 30 can be evenly stressed, which is conducive to reducing the amount of shaking during the opening and closing process of the door. In addition, when the door is in a closed state, due to the symmetrical design of the rotation axis of the hinge device 100, it is conducive to making the hinge device 100 and the door evenly stressed and the amount of sinking small, so that the door has a better closing and holding performance.

[0075] Alternatively, if Figure 2 As shown, the third connecting arm 61 can be rotatably connected to the first connecting arm 40 around the third rotation axis 104, the first connecting arm 40 can be rotatably connected to the second connecting arm 50 around the fourth rotation axis 105, and the third rotation axis 104 and the fourth rotation axis 105 are arranged symmetrically.

[0076] Similarly, since the third rotation axis 104 can be arranged symmetrically with the fourth rotation axis 105, during the rotation process, the structure composed of the third connecting arm 61 and the first connecting arm 40 and the structure composed of the first connecting arm 40 and the second connecting arm 50 can be evenly stressed, which is beneficial to reducing the shaking amount during the opening and closing process of the door. When the door is in the closed state, due to the symmetrical design of the rotation axis of the hinge device 100, it is beneficial to make the hinge device 100 and the door evenly stressed and the amount of sinking is small, so that the door has a better closing and holding performance.

[0077] Alternatively, if Figure 2 As shown, the third connecting arm 61 is rotatably connected to the first rotating block 20 around the fifth rotating axis 103, the second connecting arm 50 is rotatably connected to the second rotating block 30 around the sixth rotating axis 106, and the fifth rotating axis 103 and the sixth rotating axis 106 are symmetrically arranged. With such a design, during the rotation process, the structure composed of the third connecting arm 61 and the first rotating block 20 and the structure composed of the second connecting arm 50 and the second rotating block 30 can be evenly stressed, which is beneficial to reducing the shaking amount during the opening and closing process of the door. When the door is in the closed state, due to the symmetrical design of the rotating axis of the hinge device 100, it is beneficial to make the hinge device 100 and the door evenly stressed and the amount of sinking is small, so that the door has a better closing and holding performance.

[0078] Especially in the implementation where the first rotation axis 101 and the second rotation axis 102 are symmetrically arranged, the third rotation axis 104 and the fourth rotation axis 105 are symmetrically arranged, and the fifth rotation axis 103 and the sixth rotation axis 106 are also symmetrically arranged, the improvements in the shaking amount, force uniformity and closing retention performance during the door opening and closing process are particularly obvious.

[0079] For example, see Figure 2 In one embodiment of the present disclosure, the first rotation axis 101 and the second rotation axis 102 intersect at a first point P1, the third rotation axis 104 and the fourth rotation axis 105 intersect at a second point P2, the first rotation axis 101 and the second rotation axis 102 are configured to be symmetrically arranged about the line connecting the first point P1 and the second point P2, the third rotation axis 104 and the fourth rotation axis 105 are configured to be symmetrically arranged about the line connecting the first point P1 and the second point P2, and the fifth rotation axis 103 and the sixth rotation axis 106 are configured to be symmetrically arranged about the line connecting the first point P1 and the second point P2. In this way, when opening and closing the door, the rotation of the structure composed of the first rotating block 20, the third connecting arm 61, and the first connecting arm 40 and the structure composed of the first connecting arm 40, the second connecting arm 50, and the second rotating block 20 is always symmetrical.

[0080] In addition to achieving a symmetrical arrangement of the rotation axis, such as Figures 1 to 3 As shown, the first part of the first rotating block 20, the third connecting arm 61 and the first support arm 41 can be constructed as a first motion component, wherein the first part is the part of the first rotating block 20 located between the first intersection P1 and the third intersection P3, the second support arm 42, the second connecting arm 50 and the second rotating block 30 can be constructed as a second motion component, and the first motion component and the second motion component can be constructed to be symmetrical about the first normal plane, the first normal plane is the normal plane of the first surface 11 of the mounting base 10 facing the swing arm 60, and the line connecting the first point P1 and the second point P2 is located in the normal plane.

[0081] The symmetrical design of the structure enables at least part of the structure of the hinge device 100 to be set as a symmetrical mechanism, which is conducive to simplifying the structure. Moreover, since the symmetrical structure has good stability and uniform force, it is conducive to further reducing the shaking amount during the opening and closing process of the door. In addition, when the door is in the closed state, due to the symmetrical design of the hinge device 100, the hinge device 100 and the door can be further uniformly stressed and the sinking amount is small, so that the door has a better closing and holding performance.

[0082] In order to improve the stability of the hinge device 100 structure, Figures 1 to 3 As shown, in one embodiment of the present disclosure, the first connecting arm 40 may include a first support arm 41 and a second support arm 42, the first support arm 41 is rotatably connected to the swing arm 60 around a third rotation axis 104, the second support arm 42 is rotatably connected to the second connecting arm 50 around a fourth rotation axis 105, the first rotating block 20, the first part 61 of the swing arm 60 and the first support arm 41 can construct the above-mentioned first motion assembly, and the second support arm 42, the second connecting arm 50 and the second rotating block 30 can construct a second motion assembly.

[0083] In addition, since the first moving component and the second moving component are constructed as a symmetrical structure, the hinge device 100 is constructed as a structure that is symmetrical about the first normal plane movement. With such a design, during the opening or closing process of the vehicle door, the first rotating block 20 and the second rotating block 30 can respectively rotate in opposite directions at a constant speed, and the swing arm and the second connecting arm 50 can respectively make symmetrical spatial movements at a constant speed.

[0084] It is understandable that in other embodiments of the present disclosure, the first motion component and the second motion component may not be symmetrical structures, as long as the vehicle door can be opened and closed according to a preset trajectory, and the present disclosure does not limit this.

[0085] Alternatively, if Figures 1 to 3 As shown, the first connecting arm 40 is constructed by a first support arm 41 and a second support arm 42, and the first support arm 41 and the second support arm 42 are connected to form a V-shaped symmetrical structure. Such a design is beneficial to improving the uniformity of the force on the first connecting arm 40 and improving the stability of the movement. At the same time, it can also simplify the structure of the first connecting arm 40.

[0086] The present disclosure does not limit the structure for realizing the rotatable connection between the first connecting arm 40 and the third connecting arm 61 and the second connecting arm 50. Figures 1 to 3As shown, in one embodiment of the present disclosure, a first mounting hole is provided on the third connecting arm 61, and the first support arm 41 is configured as a first rotating shaft, which is rotatably inserted into the first mounting hole around a third rotating axis 104, where the third rotating axis 104 is the axis of the first rotating shaft. A second mounting hole is provided on the second connecting arm 50, and the second support arm 42 is configured as a second rotating shaft, which is rotatably inserted into the second mounting hole around a fourth rotating axis 105, where the fourth rotating axis 105 is the axis of the second rotating shaft.

[0087] It is understandable that in other embodiments of the present disclosure, mounting holes may be provided on the first support arm 41 and the second support arm 42 , and rotating shafts cooperating with the mounting holes may be provided on the swing arm 60 and the second connecting arm 50 .

[0088] The present disclosure does not limit the structure for realizing the rotatable connection between the third connecting arm 61 and the first rotating block 20, and between the second connecting arm 50 and the second rotating block 30. Figures 1 to 3 As shown, in one embodiment of the present disclosure, a third mounting hole is further provided on the third connecting arm 61, a third rotating shaft 21 is provided on the first rotating block 20, and the third rotating shaft 21 is inserted into the third mounting hole around the fifth rotating axis 103, where the fifth rotating axis 103 is the axis of the third rotating shaft 21. A fourth mounting hole is further provided on the second connecting arm 50, a fourth rotating shaft 31 is provided on the second rotating block 30, and the fourth rotating shaft 31 is inserted into the fourth mounting hole around the sixth rotating axis 106, where the sixth rotating axis 106 is the axis of the fourth rotating shaft 31.

[0089] It is understandable that in other embodiments of the present disclosure, mounting holes may be provided on the first rotating block 20 and the second rotating block 30 , and rotating shafts cooperating with the mounting holes may be provided on the third connecting arm 61 and the second connecting arm 50 .

[0090] In this disclosure, see Figure 2 Optionally, the first rotation axis 101, the fifth rotation axis 103 and the third rotation axis 104 intersect at a third point P3. Optionally, any two of the first point P1, the second point P2 and the third point P3 do not overlap.

[0091] Alternatively, if Figure 2 As shown, the sixth rotation axis 106 , the fourth rotation axis 105 and the second rotation axis 102 intersect at a fourth point P4 , and any two of the first point P1 , the second point P2 , the third point P3 and P4 do not coincide with each other.

[0092] In the present disclosure, the rotation axes corresponding to the various rotating parts in the six-bar mechanism formed by the mounting base 10, the first rotating block 20, the second rotating block 30, the first connecting arm 40, the second connecting arm 50 and the third connecting arm 61 (connecting arm 60) intersect at multiple points. Compared with the solution in the prior art that the spatial four-bar linkage requires the intersection at one point, the multi-point solution provided by the present application is conducive to reducing the difficulty of processing and assembly.

[0093] like Figure 2 As shown, optionally, the first rotation axis 101 and the second rotation axis 102 are located in the XZ plane (i.e., the plane defined by the X direction and the Z direction), the first rotation axis 101 can be arranged along the Z direction, and the second rotation axis 102 can be arranged obliquely to have an angle with the Z direction. The angle between the first rotation axis 101 and the second rotation axis 102 is a first angle α, the angle between the first rotation axis 101 and the fifth rotation axis 103 is a second angle β; the angle between the first rotation axis 101 and the third rotation axis 104 is a third angle γ, and the first angle α, the second angle β and the third angle γ are all acute angles. The angle of the first angle α and the angle of the second angle β are set to remain constant during the swinging process of the swing arm 60, for example, see Figure 1 and Figure 2 After the first rotating block 20 and the second rotating block 30 are installed on the mounting base 10, the angle between the first rotating axis 101 and the second rotating axis 102 remains unchanged, and the third rotating shaft 21 is fixed on the first rotating block 20, so the angle of the second angle β can be kept constant. The third angle γ changes during the swinging process of the swing arm 60. The angles of the first angle α and the second angle β are used to limit the outward swing angle of the swing arm 60 in the Y direction, and the angle of the third angle γ is used for the upward swing angle of the swing arm 60 in the Z direction.

[0094] During the rotation of the first rotating block 20 around the first rotating axis 101, the swing arm 60 rotates around the third connecting arm 61 and the first rotating block 20, and at the same time, the swing arm 60 rotates upward around the fifth rotating axis 103 following the third connecting arm 61, thereby realizing the upward rotation of the door. During the upward rotation, the swing arm 60 rotates outward in the Y direction following the third connecting arm 61 around the third rotating axis 104, thereby realizing the upward swing of the door in the Y direction and the Z direction at the same time.

[0095] The present disclosure does not limit the specific shapes of the swing arm and the movement trajectory of the door. Optionally, in one embodiment of the present disclosure, in the plane coordinates defined by the X direction and the Z direction, the movement trajectory of the swing arm during the opening or closing process of the door is a cosine curve. That is, the swing arm presents an arc-shaped movement trajectory in the plane coordinates defined by the X direction and the Z direction.

[0096] The present disclosure does not limit the lateral opening angle and the upward opening angle of the vehicle door. Optionally, in one embodiment of the present disclosure, the first rotation axis extends along the Z direction. In the process of switching the vehicle door from a closed state to a fully open state, the swing arm 60 follows the third connecting arm 61 to rotate outward around the first rotation axis 101 in the XY plane (i.e., the plane defined by the X direction and the Y direction) at an angle less than or equal to 45°, and the swing arm 60 follows the third connecting arm 61 to rotate upward around the third rotation axis 103 in the YZ plane (i.e., the plane defined by the Y direction and the Z direction) at an angle less than or equal to 50°.

[0097] In the present disclosure, the first rotating block 20 and the second rotating block 30 can be installed on the mounting base 10 using any appropriate structure. Figure 1 and Figure 4 As shown, in one embodiment of the present disclosure, the hinge device 100 also includes a first mounting bracket and a second mounting bracket, the first mounting bracket includes a pair of first lugs 12, and the pair of first lugs 12 are arranged at intervals on the mounting base 10, and the two ends of the first rotating block 20 are respectively rotatably mounted on the corresponding first lugs 12 around the first rotation axis 101. For example, the two ends of the first rotating block 20 are respectively rotatably mounted on the corresponding first lugs 12 through a fourth rotating shaft, and the axis of the fourth rotating shaft is the first rotation axis 101. The second mounting bracket includes a pair of second lugs 13, and the pair of second lugs 13 are arranged at intervals on the mounting base 10, and the two ends of the second rotating block 30 are respectively rotatably mounted on the corresponding second lugs 13 around the second rotation axis 102. For example, the two ends of the second rotating block 30 are respectively rotatably mounted on the corresponding second lugs 13 through a fifth rotating shaft, and the axis of the fifth rotating shaft is the second rotation axis 102.

[0098] Optionally, in the present disclosure, the first mounting bracket and the second mounting bracket may be fixed to the mounting base 10 by means such as welding or screwing.

[0099] Alternatively, in other embodiments of the present disclosure, the first mounting bracket and the second mounting bracket may be integrally formed with the mounting base 10 .

[0100] Alternatively, if Figure 1 and Figure 2As shown, in the XZ plane (i.e., in the plane defined by the X direction and the Z direction), the first rotation axis 101 is parallel to the Z direction, the second rotation axis 102 has an angle with the Z direction, and the length of the first mounting block in the Z direction is greater than the length of the second mounting block in the extension direction of the second rotation axis 102. Since the first rotation axis 101 is parallel to the Z direction, when the swing arm 60 is connected to the vehicle door, the weight of the swing arm and the vehicle door is mainly borne by the first rotating block 20, and the second rotating block 30 is tilted, so that the second rotating block 30 mainly plays the role of limiting the movement trajectory of the swing arm and the vehicle door, so the size of the second rotating block 30 on the second rotation axis 102 is allowed to be relatively small. Therefore, setting the size of the first mounting hole in the Z direction to be larger than the size of the second rotating block 30 in the extension direction of the second rotation axis 102 is conducive to ensuring the reliability of the hinge device 100 supporting the vehicle door, and also conducive to saving the size of the second rotating block 30.

[0101] In order to facilitate driving the door to rotate around the hinge device 100, at least one ball pin 70 may be provided on the swing arm 60, and the ball pin 70 is used to be connected to one end of the door stay (not shown) to rotate around the hinge device 100 under the action of an electric spring, a pneumatic spring or a balance spring. Optionally, the door stay may include an electric spring, a pneumatic spring or a balance spring type stay. During installation, the other end of the door stay may be mounted on the vehicle body. The specific structure and working principle of the door stay are well known to those skilled in the art and will not be described in detail here.

[0102] Alternatively, if Figure 1 and Figure 4 As shown, there are two ball pins 70 , and the two ball pins 70 are respectively connected to a door stay in an articulated manner.

[0103] According to another aspect of the present disclosure, a vehicle door assembly is provided, which includes a vehicle door and the above-mentioned hinge device 100. During installation, the swing arm 60 of the hinge device can be connected to the vehicle door (such as by screwing, etc.).

[0104] According to another aspect of the present disclosure, a vehicle is provided, which includes a vehicle body and the above-mentioned door assembly, wherein the mounting base 10 of the hinge device 100 is connected to the vehicle body, and the swing arm 60 is connected to the door so that the door can be hinged to the vehicle body through the hinge device 100.

[0105] The working principle and process of the hinge device 100 during the opening of the vehicle door will be briefly described below with reference to the accompanying drawings.

[0106] The door is closed as shown in the attached Figure 1 and Figure 2As shown, the swing arm 60 and the mounting base 10 are compressed as much as possible into the same YZ plane. When the door needs to be opened, the force can be applied to the points where the two ball pins 70 are located through the telescopic action of the door support rod, so that the swing arm 60 moves in space. Specifically, the swing arm 60 follows the third connecting arm 61 and simultaneously moves around the fifth rotation axis 103 and the third rotation axis 104 to open the door sideways and open the door upward. Due to the movement of the swing arm 60, the first rotating block 20 is driven to perform a fixed-axis rotational movement around the first rotation axis 101. Based on the symmetrical design, under the action of the first connecting arm 40, the second connecting arm 50 simultaneously moves in space, that is, the second connecting arm 50 simultaneously performs symmetrical movements around the sixth rotation axis 106 and the swing fourth rotation axis 105. At the same time, due to the movement of the second connecting arm 50, the second rotating block 30 is driven to perform a fixed-axis rotational movement around the second rotation axis 102.

[0107] When the first rotating block 20 rotates to 45° around the first rotating axis 101, the swing arm 60 drives the door to rotate upward to about 50° around the fifth rotating axis at the same time, and the door opening action is completed. At this time, the swing arm 60 and the door (not shown) are in the following state: Figure 4 and Figure 5 The fully open position is shown. The action of closing the door is the opposite of opening the door, so it will not be described here.

[0108] The preferred embodiments of the present disclosure are described in detail above in conjunction with the accompanying drawings; however, the present disclosure is not limited to the specific details in the above embodiments. Within the technical concept of the present disclosure, a variety of simple modifications can be made to the technical solution of the present disclosure, and these simple modifications all fall within the protection scope of the present disclosure.

[0109] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present disclosure will not further describe various possible combinations.

[0110] In addition, various embodiments of the present disclosure may be arbitrarily combined, and as long as they do not violate the concept of the present disclosure, they should also be regarded as the contents disclosed by the present disclosure.
