DETAILED DESCRIPTION

[0031] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in many forms and should not be construed as limited to the examples set forth herein; rather, these embodiments are provided so that this application will be thorough and complete and will fully convey the concepts of the example embodiments to those skilled in the art.

[0032] In addition, described feature, structure or characteristic can be combined in one or more embodiments in any suitable manner.In the following description, many specific details are provided so as to provide a full understanding of the embodiments of the present application. However, it will be appreciated by those skilled in the art that the technical scheme of the present application can be put into practice without one or more of the specific details, or other methods, components, devices, steps etc. can be adopted.

[0033] The present application is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be understood as limiting the present application.

[0034] It should be noted that the term "plurality" used in this document refers to two or more. "And / or" describes a relationship between associated objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A alone, A and B together, or B alone. The character " / " generally indicates an "or" relationship between the associated objects.

[0035] Most existing vehicles use exposed door handles, but traditional exposed handles will disrupt the airflow on the surface of the vehicle body, increase the drag coefficient, and have a negative impact on the endurance of electric vehicles or the fuel consumption of fuel vehicles.

[0036] In order to solve the above technical problems, the present application provides a vehicle door device, including a shell 10, a handle 20, a swing arm assembly 30 and a push rod assembly 40. Through the mutual cooperation between the push rod assembly 40 and the swing arm assembly 30, the handle 20 is hidden inside the door body or exposed outside the door body.

[0037] In some embodiments, reference Figures 1 to 4As shown, the shell 10 is used to connect with the door body; the handle 20 is extended along the first direction X1; the swing arm assembly 30 includes a connecting member 31, a first swing arm 32 and a second swing arm 33. The first end of the connecting member 31 is rotatably connected to the shell 10, the first end of the first swing arm 32 is rotatably connected to the second end of the connecting member 31, the second end of the first swing arm 32 is rotatably connected to the handle 20, and the second swing arm 33 is rotatably connected to the handle 20 and the shell 10 respectively; the push rod assembly 40 and the swing arm assembly 30 are located on the same side of the handle 20 and are used for sliding in the first direction X1. The push rod assembly 40 abuts the second end of the connecting member 31 and the side of the second swing arm 33 away from the handle 20 to move the handle 20 closer to or away from the shell 10. Thus, the first end of the connecting member 31 is rotatably connected to the shell 10, the first end of the first swing arm 32 is rotatably connected to the second end of the connecting member 31, the second end of the first swing arm 32 is rotatably connected to the handle 20, and the push rod assembly 40 abuts the second end of the connecting member 31, referring to Figure 2 and Figure 3 As shown, when the push rod assembly 40 moves in the first direction X1, the second end of the connecting member 31 is pushed to make the first end of the connecting member 31 rotate around the housing 10, and the first swing arm 32 and the second end of the connecting member 31 swing around the first end of the connecting member 31, the first end of the first swing arm 32 and the second end of the connecting member 31 rotate relative to each other, the second end of the first swing arm 32 rotates relative to the handle 20 and pushes the handle 20 to move to the side away from the housing 10; the second swing arm 33 is rotatably connected to the handle 20 and the housing 10 respectively, and the push rod assembly 40 abuts against the second swing arm 33 away from the handle 20. Figure 2 and Figure 3 As shown, when the push rod assembly 40 moves in the first direction X1, it pushes the second swing arm 33 away from the handle 20, causing the second swing arm 33 to rotate relative to the housing 10. The second swing arm 33 then swings closer to the handle 20, causing the second swing arm 33 to rotate relative to the handle 20, pushing the handle 20 away from the housing 10. The interaction between the push rod assembly 40 and the swing arm assembly 30 pushes the handle 20 away from the housing 10, revealing it outside the housing 10 and allowing the door to be opened. Simultaneously, the push rod assembly 40 can also reverse the motion, hiding the handle 20 within the housing 10, reducing the door assembly's drag coefficient and thus lowering the vehicle's fuel consumption.

[0038] In some embodiments, the vehicle door device of the present application can further enhance the vehicle body lines and the smoothness of the door exterior surface by designing a hidden handle 20. In low-speed collisions, the hidden handle 20 can reduce additional injuries to pedestrians, and in daily use, the hidden handle 20 can work in conjunction with the vehicle to provide enhanced anti-theft functionality.

[0039] In some embodiments, reference Figure 2As 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 in the left-to-right direction along the vehicle door device.

[0040] In some embodiments, the housing 10 forms a receiving cavity 11, and the receiving cavity 11 of the housing 10 at least has a notch facing outward from the vehicle door device. Figure 2 As shown, when the handle 20 is hidden in the door device, the handle 20 is close to the housing 10 and located in the accommodating cavity 11, and the plane of the handle 20 facing the outside of the door device, the plane of the housing 10 facing the outside of the door device, and the plane of the door body facing the outside of the door device are flush. At this time, the handle 20 is in a hidden state. Figure 3 As shown, when the vehicle is in a parked state, the handle 20 can be exposed outside the door device by operating the vehicle computer or button operation. At this time, the handle 20 is in a flat out state; Figure 4 As shown, when the handle 20 is exposed outside the door assembly, it is away from the housing 10 and outside the accommodating cavity 11. The door assembly can be unlocked by pulling the handle 20. When the door is in motion, the handle 20 can be hidden inside the door assembly by operating the vehicle computer or a button.

[0041] In some embodiments, reference Figure 3 As shown, the housing 10 further includes a stopper 12. In a first direction X1, the stopper 12 is positioned between the first swing arm 32 and the second swing arm 33. In a second direction X2, the stopper 12 is positioned between the handle 20 and the push rod assembly 40. The second direction X2 is perpendicular to the first direction X1. The stopper 12 is disposed within the accommodating cavity 11. The stopper 12 is configured as a partition structure, which prevents the handle 20 from further moving into the accommodating cavity 11 within a certain space. Specifically, the stopper 12 positioned between the handle 20 and the push rod assembly 40 not only limits the handle 20 but also shields the push rod assembly 40. When the handle is extended horizontally, the push rod assembly 40 is concealed, maintaining the overall consistency of the vehicle door. The stopper 12 is positioned between the first swing arm 32 and the second swing arm 33. A space is defined between the stopper 12 and the wall of the accommodating cavity 11 in the first direction X1, providing space for the first and second swing arms 32 and 33 to be installed and swing. When the first swing arm 32 and the second swing arm 33 swing, they neither interfere with the limiting portion 12 nor interfere with the accommodating cavity 11 , so that the handle 20 moves more smoothly in the accommodating cavity 11 .

[0042] In some embodiments, reference Figure 3As shown, the vehicle door device further includes a first elastic member 70, one side of which is connected to the first swing arm 32, and the other side of which is connected to the push rod assembly 40. The first elastic member 70 is connected between the first swing arm 32 and the push rod assembly 40. The first end of the first swing arm 32 is rotatably connected to the second end of the connecting member 31. When the pushing member 421 moves from left to right in the first direction X1, it pulls the first swing arm 32 and maintains the contact between the second end of the connecting member 31 and the pushing assembly. This prevents the second end of the connecting member 31 from colliding with the pushing assembly and generating noise during vehicle travel.

[0043] In some embodiments, reference Figure 4 As shown, the first end of the connecting member 31 and the shell 10, the first end of the first swing arm 32 and the second end of the connecting member 31, the second end of the first swing arm 32 and the handle 20, the second swing arm 33 and the handle 20, and the second swing arm 33 and the shell 10 are all connected by a rotating shaft to achieve the relative rotation between the first end of the connecting member 31 and the shell 10, the relative rotation between the first end of the first swing arm 32 and the second end of the connecting member 31, the relative rotation between the second end of the first swing arm 32 and the handle 20, the relative rotation between the second swing arm 33 and the handle 20, and the relative rotation between the second swing arm 33 and the shell 10.

[0044] In some embodiments, reference Figure 4 and Figure 5 As shown, the vehicle door device also includes a second elastic member 80, which is a torsion spring. The second elastic member 80 is arranged on the rotating shaft between the first end of the connecting member 31 and the shell 10, on the rotating shaft between the first end of the first swing arm 32 and the second end of the connecting member 31, on the rotating shaft between the second end of the first swing arm 32 and the handle 20, on the rotating shaft between the second swing arm 33 and the handle 20, and on the rotating shaft between the second swing arm 33 and the shell 10. When the handle 20 switches between the flat state and the hidden state, it can provide torsion in the radial direction of the rotating shaft, so that the first swing arm 32 and the second swing arm 33 of the handle 20 maintain abutment with the push rod assembly 40, thereby facilitating the hiding of the handle 20 in the accommodating cavity 11.

[0045] In some embodiments, reference Figure 4 and 5 As shown, the handle 20 is connected to the housing 10 via a first swing arm 32 and a second swing arm 33. The housing 10 is mounted within the door body of the vehicle door assembly. The handle 20 also needs to be connected to the unlocking assembly 60 of the vehicle door assembly to achieve unlocking and locking functions. The handle 20 extends longitudinally along the front-to-back direction of the vehicle, which is the first direction X1.

[0046] In some embodiments, reference Figure 5As shown, the push rod assembly 40 forms a hole portion 44, which extends along the first direction X1. The second swing arm 33 includes a second abutting portion 331, which protrudes from the second swing arm 33 toward the side away from the handle 20. The second abutting portion 331 is located in the hole portion 44. The second abutting portion 331 forms a third abutting surface 332, which abuts against the side wall of the hole portion 44. The hole portion 44 of the push rod assembly 40 can accommodate a portion of the second swing arm 33. When the push rod assembly 40 moves, the hole wall can apply a thrust to the second abutting portion 331, causing the second swing arm 33 to swing. The second swing arm 33 is a horizontal swing arm. The height of the first and second ends of the second swing arm 33 are both higher than the height of the second abutting portion 331, so that the second abutting portion 331 can extend into the hole portion 44.

[0047] In some embodiments, combined Figure 6 As shown, the push rod assembly 40 includes a push member 421, a connecting rod 422, and a power unit. The push member 421 is slidably connected to the side wall of the accommodating chamber 11. One side of the connecting rod 422 is connected to the push member 421, and the other side of the connecting rod 422 is connected to the power unit. The power unit can be a drive motor, which drives the connecting rod 422 to propel the push member 421 back and forth in a first direction X1. When the push member 421 moves from right to left in the first direction X1, it pushes the first swing arm 32 and the second swing arm 33 to swing clockwise, revealing the handle 20 outside the vehicle door assembly. When the push member 421 moves from left to right in the first direction X1, the push member 421 provides rebound space for the first swing arm 32 and the second swing arm 33. Under the elastic force of the second elastic member 80, the first swing arm 32 and the second swing arm 33 swing counterclockwise, thereby concealing the handle 20 inside the vehicle door assembly. Among them, when the handle 20 is exposed, the pushing member 421 can push the swing arm assembly 30, and when the handle 20 is hidden, the pushing member 421 can limit the swing arm assembly 30 to prevent the handle 20 from being excessively hidden, resulting in an uneven outer surface of the door device.

[0048] In some embodiments, combined Figure 7As shown, the connecting member 31 includes a first abutting portion 311, which is located at the second end of the connecting member 31. The first abutting portion 311 includes a first abutting surface 312 disposed at least toward the push rod assembly 40. The first abutting surface 312 is an arcuate abutting surface protruding toward the push rod assembly 40 in the first direction X1. The push rod assembly 40 is formed with a second abutting surface 41 corresponding to the first abutting surface 312. The second abutting surface 41 is inclined in the second direction X2. The second abutting surface 41 abuts against the first abutting surface 312. The force direction of the second abutting surface 41 or the first abutting surface 312 is parallel to the first direction X1, and the second direction X2 is perpendicular to the first direction X1. The arcuate abutting surface can be provided as one or more according to actual conditions, and the curvature radius of the arcuate abutting surface can be selected according to actual conditions to match the push rod assembly 40. The second abutting surface 41 can be an inclined plane, and the inclination angle can be selected according to actual conditions to match the arcuate abutting surface. The second abutting surface 41 always maintains contact with the arcuate abutting surface during the movement process, so that the force direction is parallel to the first direction X1. Taking the movement of the push rod assembly 40 from right to left along the first direction X1 as an example, during the movement of the push rod assembly 40, the second end of the connecting member 31 swings, thereby causing the first abutting surface 312 to swing, and the arcuate abutting surface maintains contact with the second abutting surface 41. The force direction of the first abutting surface 312 and the second abutting surface 41 can always remain parallel to the first direction X1. Since the push rod assembly 40 is always subjected to the force in the first direction X1, the force of the pushing member 421 can be concentrated on the main body (the main body is the part that is subjected to the strongest force), reducing the risk of deformation of the pushing member 421.

[0049] In some embodiments, combined Figure 7As shown, the arcuate abutting surface includes a first arcuate abutting surface 3121 and a second arcuate abutting surface 3122, and the first arcuate abutting surface 3121 is located on the side of the second arcuate abutting surface 3122 away from the handle 20; the second abutting surface 41 includes a first plane section 411, an inclined section 412 and a second plane section 413, and the inclined section 412 is located between the first plane section 411 and the second plane section 413, and the first plane section 411 is located on the side away from the inclined section 412 and away from the handle; when the handle 20 is in a hidden state, in the first direction X1, the vertex of the first arcuate abutting surface 3121 is on the side of the vertex of the second arcuate abutting surface 3122 close to the second abutting surface 41; in the first direction X1, the first plane section 411 is on the side of the second plane section 413 close to the connecting member 31. The curvature radius of the first curved abutting surface 3121 is smaller than the curvature radius of the second curved abutting surface 3122. When the handle 20 is in a hidden state, in the first direction X1, the vertex of the first curved abutting surface 3121 is on the side of the vertex of the second curved abutting surface 3122 close to the second abutting surface 41, so that the vertex of the first curved abutting surface 3121 is closer to the second abutting surface 41; the first planar section 411, the inclined section 412 and the second planar section 413 of the second abutting surface 41 are arranged in sequence from bottom to top in the second direction X2, and in the first direction X1, the first planar section 411 is on the side of the second planar section 413 close to the first abutting surface 312, and the first planar section 411 and the second planar section 413 are transitionally connected through the inclined section 412. When the handle 20 is in the hidden state, the push rod assembly 40 is in the first position, with the first planar section 411 abutting the first curved abutting surface 3121. When the handle 20 is in the extended state, the push rod assembly 40 is in the second position, with the second planar section 413 abutting the second curved abutting surface 3122. When the handle 20 transitions from the hidden state to the extended state, both the first curved abutting surface 3121 and the second curved abutting surface 3122 abut against the inclined section 412, which acts as a transition, thereby maintaining the force direction parallel to the first direction X1. The first position is located on the side of the second position closer to the second swing arm 33 in the first direction X1.

[0050] In some embodiments, when the handle 20 is in the hidden state, the first curved abutting surface 3121 abuts the first planar section 411. When the handle 20 transitions from the hidden state to the extended state, the first curved abutting surface 3121 abuts the inclined section 412, or the second curved abutting surface 3122 abuts the inclined section 412. When the handle is in the extended state, the second curved abutting surface 3122 abuts the second planar section 413. The hidden state and the extended state of the handle 20 are convertible. The above embodiment primarily illustrates the interplay between the first curved abutting surface 3121, the second curved abutting surface 3122, the first planar section 411, the inclined section 412, and the second planar section 413 during the transition from the hidden state to the extended state. When the handle 20 is converted from the flat state to the hidden state, the mutual cooperation relationship between the first arc-shaped abutting surface 3121, the second arc-shaped abutting surface 3122, the first plane section 411, the inclined section 412 and the second plane section 413 is the same, only the order is reversed, and they will not be described here one by one.

[0051] In some embodiments, combined Figure 7 As shown, the push rod assembly 40 includes a push member 421 and a contact member 43. The contact member 43 is provided on the side of the push member 421 facing the connecting member 31, and the contact member 43 forms a second abutting surface 41. The contact member 43 includes natural rubber and synthetic rubber. Natural rubber has high tensile strength and high resilience, and has good wear resistance, low temperature resistance and processing performance; synthetic rubber includes but is not limited to styrene-butadiene rubber, nitrile rubber, etc., which have good pressure resistance and corrosion resistance, and have a wide operating temperature range. Specifically, the contact member 43 is provided between the first abutting portion 311 and the push member 421. The contact member 43 has a better silent effect due to its material properties. When the push member 421 and the connecting member 31 are moving or rotating, the contact member 43 can reduce the noise of the collision between the two.

[0052] In some embodiments, combined Figure 8 As shown, the housing 10 forms a receiving chamber 11; the door device further includes a first rotating shaft 50 and an unlocking assembly 60. The first rotating shaft 50 passes through the side wall of the receiving chamber 11. The first rotating shaft 50 is rotatably connected to the connecting member 31 inside the receiving chamber 11, and is rotatably connected to the unlocking assembly 60 outside the receiving chamber 11. Figure 2 As shown, the accommodating cavity 11 is used to place the handle 20, the swing arm assembly 30 and the push rod assembly 40. The unlocking assembly 60 is outside the housing 10 and is located between the sheet metal sandwich layers of the door device. The unlocking assembly 60 includes a cam 61, a lock, etc. The cam 61 is shown in the figure. The cam 61 and the lock can be connected by a rope. Figure 3As mentioned above, when the handle 20 is in the horizontally extended position, it is necessary to continue to apply a pulling force outside the door assembly to pull the handle 20 to unlock it. Specifically, when the handle 20 is horizontally extended, the space between the first swing arm 32 and the second swing arm 33 is also exposed outside the door housing 10, creating a force-bearing space. Applying a pulling force in the force-bearing space causes the handle 20 to rotate about the rotation axis, causing the connecting member 31 and the first swing arm 32 to continue to rotate clockwise. This, in turn, drives the cam 61 to rotate clockwise via the rotation axis, driving the rope to pull the lock catch to unlock the door.

[0053] In some embodiments, combined Figure 9 As shown, the connecting member 31 is formed with a first shaft hole 314 corresponding to the first rotating shaft 50, and the inner wall of the first shaft hole 314 forms a groove 3141; the outer wall of the first rotating shaft 50 forms a protrusion 51, and the protrusion 51 is located in the groove 3141. The width of the protrusion 51 in the radial direction of the first shaft hole 314 is smaller than the width of the groove 3141. Therefore, there is an idle stroke between the protrusion 51 and the groove 3141. This idle stroke does not drive the first rotating shaft 50 to rotate during the process of the handle 20 being converted from the hidden state to the horizontally extended state, and further does not drive the unlocking assembly 60 to rotate, thereby maintaining the locked state of the vehicle door device. When the handle 20 is converted from the horizontally extended state to the unlocked state, the groove 3141 abuts against the protrusion 51 in the clockwise direction, and the handle 20 is continuously pulled so that the handle 20 drives the first rotating shaft 50 to rotate through the first swing arm 32 and the connecting member 31, thereby driving the unlocking assembly 60 to rotate and achieve unlocking. Refer to Figure 10 and Figure 11 As shown, the groove 3141 on the inner wall of the first shaft hole 314 can be a keyway, and the width of the keyway gradually decreases from the side close to the unlocking assembly 60 to the side away from the unlocking assembly 60. Part of the first rotating shaft 50 extends out of the housing 10, and part of the first rotating shaft 50 is in the accommodating cavity 11, wherein part of the protrusion 51 is located in the first shaft hole 314 and cooperates with the groove 3141, and part of the protrusion 51 is located outside the accommodating cavity 11 and cooperates with the unlocking assembly 60. The protrusion 51 can be a key, and the width of the key gradually decreases from the side close to the unlocking assembly 60 to the side away from the unlocking assembly 60. This design facilitates the mating installation of the protrusion 51 and the groove 3141.

[0054] In some embodiments, combined Figure 9As shown, a first track 3142 is defined between the walls of the groove 3141 in the radial direction of the first rotating shaft 50. The length of the first track 3142 is equal to the width of the groove 3141, and the protrusion 51 is located within the first track 3142. When the handle 20 is in the hidden state, the protrusion 51 abuts against one side of the groove wall. When the handle 20 is moved from the hidden state to the horizontally extended state, the protrusion 51 moves along the first track 3142. When the handle 20 is in the horizontally extended state, the protrusion 51 abuts against the other side of the groove wall. When the handle 20 is moved from the horizontally extended state to the unlocked state, the protrusion 51 drives the other side of the groove wall to rotate in the radial direction of the first rotating shaft 50, thereby rotating the unlocking assembly 60. The first track 3142 is an arc-shaped track, extending from the groove wall of one groove 3141 to the groove wall of the other groove 3141. The protrusions 51 are movable within the first tracks 3142. Because the length of the first tracks 3142 is greater than the width of the protrusions 51, the protrusions 51 have an idle travel within the groove 3141. When the handle 20 is switched between the concealed and extended positions, the protrusions 51 rotate within the idle travel but do not rotate the groove walls. When the handle 20 is switched from the extended position to the unlocked position, the protrusions 51 rotate the groove walls on the other side radially along the first rotating shaft 50, causing the unlocking assembly 60 to rotate.

[0055] In some embodiments, the push rod assembly 40 forms a hole portion 44 extending along the first direction X1. The second swing arm 33 includes a second abutting portion 331 protruding from the second swing arm 33 toward the side away from the handle 20. The second abutting portion 331 is located in the hole portion 44. The second abutting portion 331 forms a third abutting surface 332, which abuts against the sidewall of the hole portion 44. The hole portion 44 of the push rod assembly 40 can accommodate a portion of the second swing arm 33. When the push rod assembly 40 moves, the hole wall can apply a thrust to the second abutting portion 331 to cause the second swing arm 33 to swing. The second swing arm 33 is a horizontal swing arm. The heights of the first and second ends of the second swing arm 33 are both higher than the height of the second abutting portion 331, so that the second abutting portion 331 can extend into the hole portion 44.

[0056] In the present application, when the vehicle is in a parked state, a command can be issued by operating the vehicle computer or buttons to make the handle 20 appear outside the door device, and at this time the handle 20 is in a horizontally extended state; when the door is in a driving state, a command can be issued by operating the vehicle computer or buttons to make the handle 20 hidden inside the door device, and at this time the handle 20 is in a hidden state. When the push rod assembly 40 moves in the first direction X1, it pushes the second end of the connecting member 31, causing the first end of the connecting member 31 to rotate about the housing 10. The first swing arm 32 and the second end of the connecting member 31 swing about the first end of the connecting member 31. The first end of the first swing arm 32 and the second end of the connecting member 31 rotate relative to each other. The second end of the first swing arm 32 rotates relative to the handle 20 and pushes the handle 20 to move away from the housing 10. When the push rod assembly 40 moves in the first direction X1, it pushes the second swing arm 33 away from the handle 20, causing the second swing arm 33 to rotate relative to the housing 10. The second swing arm 33 swings toward the handle 20 and rotates relative to the handle 20, pushing the handle 20 away from the housing 10. The interaction between the push rod assembly 40 and the swing arm assembly 30 pushes the handle 20 away from the housing 10, causing the handle 20 to appear outside the housing 10, thereby opening the vehicle door. At the same time, the reverse action can also be performed to hide the handle 20 in the housing 10, thereby reducing the wind resistance coefficient of the door device and thus reducing the fuel consumption of the vehicle.

[0057] The present application also provides a vehicle, comprising the above-mentioned door device.

[0058] The present application also provides a method for opening and closing a vehicle door device, specifically comprising the following steps: referring to Figures 1 to 4 As shown, when the push rod assembly 40 moves in the first direction X1, it pushes the second end of the connecting member 31, causing the first end of the connecting member 31 to rotate about the housing 10. The first swing arm 32 and the second end of the connecting member 31 swing about the first end of the connecting member 31. The first end of the first swing arm 32 and the second end of the connecting member 31 rotate relative to each other. The second end of the first swing arm 32 rotates relative to the handle 20 and pushes the handle 20 away from the housing 10. When the push rod assembly 40 moves in the first direction X1, it pushes the second swing arm 33 away from the handle 20, causing the second swing arm 33 to rotate relative to the housing 10. The second swing arm 33 swings closer to the handle 20 and rotates relative to the handle 20, pushing the handle 20 away from the housing 10. When the handle 20 moves away from the housing 10, a tensile force is applied to the handle 20, causing the connecting member 31 to rotate via the first swing arm 32. The connecting member 31 then drives the unlocking assembly 60 to rotate via the first rotating shaft 50, thereby unlocking the door device.
