DETAILED DESCRIPTION

[0061] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present disclosure, and are not intended to limit the present disclosure.

[0062] In the present disclosure, the orientation words such as "longitudinal", "transverse", "upper", "lower", "front", "rear", "left", "right", "inner", "outer" and the like used to indicate the orientation or positional relationship are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present disclosure and simplifying the description, and are not intended to indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present disclosure. For example, the up, down, left, right, front, rear directions can be consistent with the up, down, left, right, front, rear directions of the vehicle. The Z direction can be consistent with the upward direction in the up-down direction (i.e. height direction) of the vehicle, the X direction can be consistent with the forward direction in the front-rear direction (i.e. length direction, i.e. longitudinal direction) of the vehicle, and the Y direction can be consistent with the direction away from the center surface of the longitudinal direction in the left-right direction (i.e. width direction, i.e. transverse direction) of the vehicle, which can be specifically referred to the coordinate directions in Figure 1 、 Figure 2 、 Figure 4 and Figure 5 .

[0063] In addition, in the present disclosure, the terms "first", "second" and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0064] In addition, in the present disclosure, unless specifically defined and limited otherwise, the terms "mount", "connect", "connection", and "communication" should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integrally connected; can be mechanical connection; can be directly connected, or indirectly connected through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the present disclosure can be understood according to the specific circumstances.

[0065] For the scissor door, a hinge structure is connected to the vehicle body to realize the swing of the door in the lateral direction (i.e. Y direction, the width direction of the vehicle) and the swing in the up-down direction (i.e. Z direction, the height direction of the vehicle) to realize the lateral outward (i.e. Y direction outward) and upward (i.e. Z direction upward) of the door to open the door, and the lateral inward (i.e. Y direction inward) and downward (i.e. Z direction downward) of the door to close the door.

[0066] As shown in Figures 1 to 5 The present disclosure provides a hinge device 100, which comprises 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 to the vehicle body, for example, mounted (such as screwed) to the side wall of the vehicle body, the first rotating block 20 is rotatably connected to the mounting base 10 around the first rotating axis 101, the second rotating block 30 is rotatably connected to the mounting base 10 around the second rotating axis 102, the third connecting arm 61 is connected to the swing arm 60, one end of the third connecting arm 61 is rotatably connected to the first rotating block 20, 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, 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 the door (such as the scissor door), so that through reasonable installation of the hinge device, the swing arm 60 can swing in the Y direction (the width direction of the vehicle) and the Z direction (the height direction of the vehicle), so that the door can swing in the Y direction and the Z direction, realizing the opening and closing of the door.

[0067] When mounted, the front end of the door (such as the scissor door and other special-shaped doors) can be hinged to the vehicle body through the hinge device 100, when the swing arm 60 swings outward in the Y direction and upward in the Z direction, the rear end of the door can swing outward in the Y direction and upward in the Z direction around the hinge device 100, thereby realizing the opening of the door. When it is needed to close the door, the swing arm 60 can be swung inward in the Y direction and downward in the Z direction, thereby realizing the closing of the door.

[0068] In the hinge device 100 provided in the present disclosure, 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 configured as a structure of a multi-link mechanism, specifically, can be configured as a structure similar to a six-link mechanism, when applied to a vehicle, the smooth opening and closing of a door (such as a scissor door) can be realized.

[0069] In addition, research has found that in the related art, the hinge structure applied to a scissor door usually adopts a spatial four-link and a derivative of the four-link, which requires the rotating axes of each link to intersect at a point, resulting in high machining precision and assembly precision of the hinge structure, and the machining process and assembly are difficult to control.

[0070] Compared with the existing spatial four-link mechanism with high assembly precision, the hinge device 100 of the present disclosure can not require the multiple rotating axes of the hinge device 100 to intersect at a point, thus facilitating the reduction of machining precision and assembly difficulty.

[0071] It can be understood that in the present disclosure, the third connecting arm 61 can be integrally formed on the swing arm 60, at this time, the third connecting arm 61 can be a first part of the swing arm 60, the third connecting arm 61 and the swing arm 60 can also be separately machined, and the third connecting arm 61 is connected to the swing arm 60 by welding or the like. In addition, it can be understood that the door of the present disclosure can be a scissor door and other special-shaped doors suitable for being opened and closed by the hinge device provided in the present disclosure, and the present disclosure does not limit this.

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

[0073] There are various ways to achieve rotatable connection between the above-mentioned components of the hinge device, such as Figure 1 and Figure 2As shown, 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 are connected by a revolute joint. That is, the mounting base 10 and the first rotating block 20 can be connected by a revolute joint, the first rotating block 20 and the third connecting arm 61 can be connected by a revolute joint, the third connecting arm 61 and the first connecting arm 40 can be connected by a revolute joint, the first connecting arm 40 and the second connecting arm 50 can be connected by a revolute joint, the second connecting arm 50 and the second rotating block 30 can be connected by a revolute joint, and the second rotating block 30 and the mounting base 10 can be connected by a revolute joint. Revolute joint connections allow for surface-to-surface contact, thereby improving the reliability of the two relatively rotating components.

[0074] like Figure 2 and Figure 3 As shown, in one embodiment of this disclosure, the first rotation axis 101 and the second rotation axis 102 are arranged symmetrically. The symmetrical arrangement of the first rotation axis 101 and the second rotation axis 102 facilitates the design of the motion trajectories of the first rotating block 20 and the second rotating block 30, thereby simplifying the motion trajectory of the hinge device. Furthermore, because the first rotation axis 101 and the second rotation axis 102 are arranged symmetrically, the first rotating block 20 and the second rotating block 30 can be subjected to uniform force during rotation, which helps to reduce the amount of swaying during the opening and closing of the car door. In addition, when the car door is in the closed state, the symmetrical design of the rotation axis of the hinge device 100 helps to ensure that the hinge device 100 and the car door are subjected to uniform force and have a small amount of downward displacement, thereby giving the car door superior closing and holding performance.

[0075] Optionally, such as 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, and the first connecting arm 40 can be rotatably connected to the second connecting arm 50 around the fourth rotation axis 105. The third rotation axis 104 and the fourth rotation axis 105 are arranged symmetrically.

[0076] Similarly, since the third rotation axis 104 can be symmetrically arranged with the fourth rotation axis 105, during rotation, 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 subjected to uniform force, which helps to reduce the amount of shaking during the opening and closing of the car door. When the car door is in the closed state, due to the symmetrical design of the rotation axis of the hinge device 100, the hinge device 100 and the car door are subjected to uniform force and the amount of sinking is small, thus giving the car door better closing and holding performance.

[0077] Optionally, such asFigure 2 As shown, the third connecting arm 61 is rotatably connected with the first rotating block 20 around a fifth rotating axis 103, the second connecting arm 50 is rotatably connected with the second rotating block 30 around a sixth rotating axis 106, and the fifth rotating axis 103 and the sixth rotating axis 106 are symmetrically arranged. In this way, during rotation, 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 uniformly stressed, which is conducive to reducing the amount of shaking during opening and closing of the door. When the door is in a closed state, due to the symmetrical design of the rotating axes of the hinge device 100, the hinge device 100 and the door are uniformly stressed and have a small amount of sinking, thereby making the door have a better closing retention performance.

[0078] Especially in the embodiment where the first rotating axis 101 and the second rotating axis 102 are symmetrically arranged, the third rotating axis 104 and the fourth rotating axis 105 are symmetrically arranged, and the fifth rotating axis 103 and the sixth rotating axis 106 are also symmetrically arranged, the improvement in the amount of shaking during opening and closing of the door, the uniformity of stress, and the closing retention performance is particularly obvious.

[0079] For example, referring to Figure 2 In an embodiment of the present disclosure, the first rotating axis 101 and the second rotating axis 102 intersect at a first point P1, the third rotating axis 104 and the fourth rotating axis 105 intersect at a second point P2, the first rotating axis 101 and the second rotating axis 102 are configured to be symmetrically arranged about the line connecting the first point P1 and the second point P2, the third rotating axis 104 and the fourth rotating axis 105 are configured to be symmetrically arranged about the line connecting the first point P1 and the second point P2, and the fifth rotating axis 103 and the sixth rotating axis 106 are configured to be symmetrically arranged about the line connecting the first point P1 and the second point P2. In this way, during opening and closing of 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 being able to achieve symmetrical arrangement of the rotating axes, as Figures 1 to 3 As shown, the first part of the first rotating block 20, the third connecting arm 61, and the first branch arm 41 can be configured as a first motion assembly, wherein the first part is the part of the first rotating block 20 located between the first intersection point P1 and the third intersection point P3, the second branch arm 42, the second connecting arm 50, and the second rotating block 30 can be configured as a second motion assembly, and the first motion assembly and the second motion assembly can be configured to be symmetrical about a first normal plane, the first normal plane being 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 makes at least part of the structure of the hinge device 100 be a symmetrical mechanism, which is beneficial to simplify the structure, and due to the good stability of the symmetrical structure and the uniform stress, the swing amount of the vehicle door during opening and closing is further reduced. In addition, when the vehicle door is in the closed state, due to the symmetrical design of the structure of the hinge device 100, the hinge device 100 and the vehicle door are uniformly stressed and have a small amount of sinking, so that the vehicle door has good closing retention performance.

[0082] In order to improve the stability of the structure of the hinge device 100, as shown in Figures 1 to 3 In an embodiment of the present disclosure, the first connecting arm 40 can include a first branch arm 41 and a second branch arm 42, the first branch arm 41 is rotatably connected with the swing arm 60 around the third rotation axis 104, and the second branch arm 42 is rotatably connected with the second connecting arm 50 around the fourth rotation axis 105. The first rotation block 20, the first part 61 of the swing arm 60 and the first branch arm 41 can constitute the first motion assembly, and the second branch arm 42, the second connecting arm 50 and the second rotation block 30 can constitute the second motion assembly.

[0083] In addition, since the first motion assembly and the second motion assembly are configured as a symmetrical structure, the hinge device 100 is configured as a structure symmetrical about the first normal plane motion. In this way, during the opening and closing of the vehicle door, the first rotation block 20 and the second rotation block 30 can respectively make reverse rotation at a constant speed, and the swing arm and the second connecting arm 50 can respectively make symmetrical spatial motion at a constant speed.

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

[0085] Optionally, as shown in Figures 1 to 3 The first connecting arm 40 is configured by the first branch arm 41 and the second branch arm 42, and the first branch arm 41 and the second branch arm 42 are connected in a V-shaped symmetrical structure. In this way, the uniformity of the stress on the first connecting arm 40 is improved, the stability of the motion is improved, and the structure of the first connecting arm 40 is also simplified.

[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. As Figures 1 to 3As shown, in one embodiment of this disclosure, the third connecting arm 61 is provided with a first mounting hole, and the first support arm 41 is constructed as a first rotating shaft. The first rotating shaft is rotatably inserted into the first mounting hole around a third rotation axis 104, where the third rotation axis 104 is the axis of the first rotating shaft. The second connecting arm 50 is provided with a second mounting hole, and the second support arm 42 is constructed as a second rotating shaft. The second rotating shaft is rotatably inserted into the second mounting hole around a fourth rotation axis 105, where the fourth rotation axis 105 is the axis of the second rotating shaft.

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

[0088] This disclosure does not limit the structure in which the third connecting arm 61 and the first rotating block 20, and the second connecting arm 50 and the second rotating block 30 are rotatably connected. For example... Figures 1 to 3 As shown, in one embodiment of this disclosure, the third connecting arm 61 is further provided with a third mounting hole, and the first rotating block 20 is provided with a third rotating shaft 21. The third rotating shaft 21 is inserted into the third mounting hole around a fifth rotating axis 103, where the fifth rotating axis 103 is the axis of the third rotating shaft 21. The second connecting arm 50 is further provided with a fourth mounting hole, and the second rotating block 30 is provided with a fourth rotating shaft 31. The fourth rotating shaft 31 is inserted into the fourth mounting hole around a sixth rotating axis 106, where the sixth rotating axis 106 is the axis of the fourth rotating shaft 31.

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

[0090] See also in this disclosure 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 coincide.

[0091] Optionally, such as Figure 2 As shown, the sixth rotation axis 106, the fourth rotation axis 105, and the second rotation axis 102 intersect at the fourth point P4. No two of the first point P1, the second point P2, the third point P3, and P4 coincide.

[0092] In the present disclosure, the six-bar mechanism composed of 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) is configured such that the intersecting points of the corresponding rotating axes of each rotating member are multiple points. Compared with the prior art scheme in which the spatial four-bar linkage is required to intersect at one point, the scheme provided in the present application is advantageous in reducing the difficulty of machining and assembly.

[0093] As shown in Figure 2 , optionally, the first rotating axis 101 and the second rotating axis 102 are located in the XZ plane (i.e., the plane defined by the X direction and the Z direction), the first rotating axis 101 can be arranged along the Z direction, and the second rotating axis 102 can be arranged obliquely with an included angle with the Z direction. The included angle between the first rotating axis 101 and the second rotating axis 102 is a first included angle α, the included angle between the first rotating axis 101 and the fifth rotating axis 103 is a second included angle β, and the included angle between the first rotating axis 101 and the third rotating axis 104 is a third included angle γ; the first included angle α, the second included angle β and the third included angle γ are all acute angles. The angles of the first included angle α and the second included angle β are set to remain constant during the swinging of the swing arm 60, for example, referring to 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 included angle between the first rotating axis 101 and the second rotating axis 102 remains unchanged, the third rotating shaft 21 is fixed on the first rotating block 20, and thus the angle of the second included angle β can remain constant. The third included angle γ changes during the swinging of the swing arm 60, and the angles of the first included angle α and the second included angle β are used to limit the angle of the swing arm 60 swinging outward in the Y direction, and the angle of the third included angle γ is used to limit the angle of the swing arm 60 swinging upward 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 of the swing arm 60, the swing arm 60 simultaneously rotates outward in the Y direction around the third rotating axis 104 following the third connecting arm 61, thereby simultaneously realizing the swinging of the door in the Y direction and the Z direction.

[0095] The present disclosure does not limit the specific shape of the swing arm and the movement trajectory of the door, and optionally, in an embodiment of the present disclosure, in the planar coordinates defined by the X direction and the Z direction, the movement trajectory of the swing arm during the opening or closing of the door is a cosine curve. That is, the swing arm presents a circular arc-shaped movement trajectory in the planar 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. In an embodiment of the present disclosure, the first rotation axis extends in the Z direction, and during the switching of the vehicle door from the closed state to the fully open state, the swing arm 60 follows the third connecting arm 61 to rotate outward in the XY plane (i.e., in the plane defined by the X direction and the Y direction) about the first rotation axis 101 by an angle less than or equal to 45°, and the swing arm 60 follows the third connecting arm 61 to rotate upward in the YZ plane (i.e., in the plane defined by the Y direction and the Z direction) about the third rotation axis 103 by an angle less than or equal to 50°.

[0097] In the present disclosure, the first rotation block 20 and the second rotation block 30 can be mounted on the mounting base 10 in any suitable structure. Optionally, as shown in Figure 1 and Figure 4 In an embodiment of the present disclosure, the hinge device 100 further includes a first mounting bracket and a second mounting bracket. The first mounting bracket includes a pair of first lugs 12 arranged at intervals on the mounting base 10, and the two ends of the first rotation block 20 are rotatably mounted on the corresponding first lugs 12 about the first rotation axis 101, for example, the two ends of the first rotation block 20 are rotatably mounted on the corresponding first lugs 12 through fourth rotation shafts, and the axis of the fourth rotation shafts is the first rotation axis 101. The second mounting bracket includes a pair of second lugs 13 arranged at intervals on the mounting base 10, and the two ends of the second rotation block 30 are rotatably mounted on the corresponding second lugs 13 about the second rotation axis 102, for example, the two ends of the second rotation block 30 are rotatably mounted on the corresponding second lugs 13 through fifth rotation shafts, and the axis of the fifth rotation shafts is the second rotation axis 102.

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

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

[0100] Optionally, as shown in Figure 1 and Figure 2As shown, in the XZ plane (i.e. 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 direction of extension 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 rotation block 20, and the second rotation block 30 is mainly used to limit the movement track of the swing arm and the vehicle door due to the inclined arrangement of the second rotation block 30, so the size of the second rotation block 30 on the second rotation axis 102 is allowed to be relatively small. Therefore, the size of the first mounting hole in the Z direction is set to be greater than the size of the second rotation block 30 in the direction of extension of the second rotation axis 102, which is beneficial to saving the size of the second rotation block 30 while ensuring the reliability of the hinge device 100 supporting the vehicle door.

[0101] In order to facilitate the driving of the vehicle door to rotate around the hinge device 100, at least one ball pin 70 can be arranged on the swing arm 60, and the ball pin 70 is used to be connected to one end of a vehicle door support rod (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 vehicle door support rod can include an electric spring, a pneumatic spring or a balance spring type support rod. When installed, the other end of the vehicle door support rod can be installed on the vehicle body. The specific structure and working principle of the vehicle door support rod are known to those skilled in the art, and will not be described here.

[0102] Optionally, as shown in Figure 1 and Figure 4 , the number of ball pins 70 is two, and the two ball pins 70 are respectively hingedly connected to one vehicle door support rod.

[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. When installed, the swing arm 60 of the hinge device can be connected to the vehicle door (such as screwing, etc.).

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

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

[0106] The closed state of the vehicle door is shown in Figure 1 and Figure 2As shown, the swing arm 60 is compressed as much as possible into the same YZ plane as the mounting base 10, when the door needs to be opened, the force can be applied to the point where the two ball head pins 70 are located through the extension and retraction 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 to simultaneously move along the combined trajectory of the fifth rotation axis 103 and the third rotation axis 104 to open the door to the side and upward. Due to the movement of the swing arm 60, the first rotating block 20 is driven to rotate around the first rotation axis 101. Based on the symmetrical design, the second connecting arm 50 simultaneously moves in space under the action of the first connecting arm 40, that is, the second connecting arm 50 simultaneously moves around the sixth rotation axis 106 and the swing fourth rotation axis 105, and at the same time, due to the movement of the second connecting arm 50, the second rotating block 30 is driven to rotate around the second rotation axis 102.

[0107] When the first rotating block 20 rotates around the first rotation axis 101 to 45°, the swing arm 60 drives the door to simultaneously rotate around the fifth rotation axis upward to about 50°, at this time, the door opening action is completed, at this time, the swing arm 60 and the door (not shown) are in the fully open position as shown. Figure 4 and Figure 5 As shown, the swing arm 60 is compressed as much as possible into the same YZ plane as the mounting base 10, when the door needs to be opened, the force can be applied to the point where the two ball head pins 70 are located through the extension and retraction 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 to simultaneously move along the combined trajectory of the fifth rotation axis 103 and the third rotation axis 104 to open the door to the side and upward. Due to the movement of the swing arm 60, the first rotating block 20 is driven to rotate around the first rotation axis 101. Based on the symmetrical design, the second connecting arm 50 simultaneously moves in space under the action of the first connecting arm 40, that is, the second connecting arm 50 simultaneously moves around the sixth rotation axis 106 and the swing fourth rotation axis 105, and at the same time, due to the movement of the second connecting arm 50, the second rotating block 30 is driven to rotate around the second rotation axis 102.

Within the technical concept range of the present disclosure, various simple modifications can be made to the technical solutions of the present disclosure, and these simple modifications all belong to the protection range of the present disclosure.

[0110] In addition, various different embodiments of the present disclosure can also be combined in any manner, as long as they do not deviate from the idea of the present disclosure, and they should also be considered as disclosed by the present disclosure.
