Description

Technical Field

[0001] The present invention relates to the field of automobile technology, and in particular to a flat-out hidden door handle, a vehicle door and a vehicle. Background Art

[0002] Traditional car exterior handles often protrude from the outside of the door panels, which not only affects the appearance of the vehicle, but also increases the wind resistance on the side of the vehicle, causing the vehicle to waste electricity and fuel, and has a significant adverse impact on the vehicle's endurance. Therefore, more and more models have adopted hidden door handles. When locked, the outer surface of the hidden door handle is flush with the outer surface of the door, which reduces wind resistance during driving and makes the vehicle look beautiful. When enabled, the hidden door handle protrudes from the outer surface of the door, making it convenient for the operator to open the door by pulling the hidden door handle.

[0003] Common hidden door handles include lever-type hidden door handles and flat-out hidden door handles. Among them, when the lever-type hidden door handle is in the enabled state, only one end protrudes from the outer surface of the door, so there is a problem of small hand operation space and inconvenient pulling operation. The flat-out hidden door handle is mostly driven by a four-bar transmission mechanism, which can protrude from the outer surface of the door as a whole, thus having a larger hand operation space and convenient for the operator to pull, but there will be problems of poor self-locking ability and easy shaking. Summary of the invention

[0009] When the push rod moves along the first track groove, the swing arm rotates around the third end of the swing arm, and the second end of the rear pull rod moves between the second track groove first position and the second track groove second position of the second track groove, so that the handle extends from or is retracted from the opening of the accommodating groove.

[0010] In one possible implementation, the actuator assembly includes an actuator body, a tension spring and a first return torsion spring, the output shaft of the actuator body is connected to the push rod, the first return torsion spring is connected between the swing arm and the handle base or the handle, so that the first end of the push rod is against the first end of the swing arm, and the tension spring is connected between the push rod and the second end of the rear rod, so that the second end of the push rod is against the second end of the rear rod.

[0011] In a possible implementation, the first end of the push rod has an inclined surface facing the first end of the swing arm and facing the opening of the accommodating groove, and the inclined surface is used to abut against the first end of the swing arm.

[0012] In a possible implementation, when the second end of the rear pull rod moves from the first position of the second track groove to the second position of the second track groove, the handle extends from the accommodating groove, and the second position of the second track groove is closer to the opening of the accommodating groove than the first position of the second track groove.

[0013] In a possible implementation manner, the second track groove gradually approaches the opening of the accommodating groove from the second track groove first position to the second track groove second position.

[0014] In a possible implementation, the flat-out hidden door handle further includes a control rod and a door outer opening cable;

[0015] The control rod is located in the receiving groove, the first end of the control rod is rotatably connected to the handle base, the control rod has a third track groove, and the third track groove can overlap with the second track groove from the first position of the second track groove to the second position of the second track groove, and the third track groove is used for the second end of the rear pull rod to move;

[0048] refer to Figure 1 and Figure 2 As shown, the flat hidden door handle includes a handle base 1, a handle 2, a transmission mechanism and an actuator assembly 4. The handle base 1 is suitable for installation on a vehicle door body. The handle base 1 has the following features: Figure 1 The receiving groove 11 shown is used to receive the handle 2, the transmission mechanism and the actuator assembly 4, and when the handle 2 is located in the receiving groove 11, the second outer surface 21 of the handle 2 is flush with the first outer surface of the door body, so that the wind resistance during driving is reduced and the appearance of the vehicle is beautiful.

[0049] refer to Figure 2 As shown, Figure 2 The diagram shows the connection structure of the flat-out hidden door handle when the handle 2 is located in the receiving groove 11, and the transmission mechanism is located on the inner side of the handle 2. The inner side of the handle 2 is the side of the handle 2 that is away from the second outer surface 21, and the outer side is opposite to the inner side and is the side facing the second outer surface 21. In this way, when the transmission mechanism moves, the handle 2 can be pushed or pulled from the inner side of the handle 2, avoiding the transmission mechanism protruding from the outer side of the handle 2, affecting the aesthetics of the handle 2 installed on the handle base 1 and being unfavorable to reducing wind resistance.

[0050] The above is an introduction to the positional relationship between the transmission mechanism and the handle 2 . The following describes the connection method between the transmission mechanism and the handle 2 and the installation method of the transmission mechanism, the handle 2 and the actuator assembly 4 in the receiving groove 11 .

[0051] refer to Figure 4 Combined with Figure 3 As shown, Figure 3 The diagram shows a connection structure of a flat-out hidden door handle when the handle 2 extends out of the receiving groove 11. The transmission mechanism is designed to drive the handle 2 to extend or retract from the opening of the receiving groove 11, so that the connection between the transmission mechanism and the handle 2 can achieve deformation between expansion and contraction. Therefore, the transmission mechanism includes a push rod 31, a swing arm 32, and a rear pull rod 33. The push rod first end 311 of the push rod 31, the swing arm first end 321 and the swing arm second end 322 of the swing arm 32, the handle first end and the handle second end of the handle 2, the rear pull rod first end 331 and the rear pull rod second end 332 of the rear pull rod 33, and the push rod second end 312 of the push rod 31 are connected in sequence so as to be relatively rotatable and to form a quadrilateral. Figure 2 As shown, the transmission mechanism and the handle 2 are in a retracted state. Figure 3 As shown, the transmission mechanism and the handle 2 are in an unfolded state.

[0052] At the same time, the third end 323 of the swing arm 32 is rotatably connected to the handle base 1, and the first track groove 112 and the second track groove 111 are provided in the accommodating groove 11. The output shaft of the actuator assembly 4 is connected to the push rod 31 and is used to drive the push rod 31 to move along the first track groove 112. The second track groove 111 is used for the movement of the second end 332 of the rear pull rod.

[0053] When the push rod 31 moves along the first track groove 112, the swing arm 32 rotates around the third end 323 of the swing arm, and the second end 332 of the rear pull rod moves between the second track groove first position a and the second track groove second position b of the second track groove 111, so that the handle 2 extends or retracts from the opening of the accommodating groove 11.

[0054] For example, when the actuator assembly 4 drives the push rod 31 to move along the first track 112 toward the first direction 1121, the first end 311 of the push rod can push the swing arm 32 to rotate positively around the third end 323 of the swing arm, so that the second end 322 of the swing arm drives the first end of the handle to move toward the outside of the opening of the receiving groove 11, and can also positively pull the second end of the handle and the first end 331 of the rear rod. At the same time, because the second end 312 of the push rod can push the second end 332 of the rear rod to move from the first position a of the second track groove 111 toward the second position b, the rear rod 33 can positively rotate around the first end 331 of the rear rod, thereby driving the second end of the handle to move toward the outside of the opening of the receiving groove 11. In this way, the first end and the second end of the handle 2 can simultaneously extend out of the receiving groove 11 from the opening of the receiving groove 11.

[0055] When the actuator assembly 4 drives the push rod 31 to move along the first track 112 toward the second direction 1122, the first end 311 of the push rod can pull the swing arm 32 to rotate in the opposite direction around the third end 323 of the swing arm, so that the second end 322 of the swing arm drives the first end of the handle to move toward the opening of the receiving groove 11, and can also push the second end of the handle and the first end 331 of the rear rod in the opposite direction. At the same time, since the second end 312 of the push rod can pull the second end 332 of the rear rod to move from the second position b of the second track groove 111 toward the first position a, the rear rod 33 can rotate in the opposite direction around the first end 331 of the rear rod, thereby driving the second end of the handle to move toward the opening of the receiving groove 11. In this way, the first end and the second end of the handle 2 can be retracted from the opening of the receiving groove 11 into the receiving groove 11 at the same time.

[0056] As can be seen from the above, the push rod 31, the swing arm 32, the handle 2 and the rear pull rod 33 are connected in sequence to form a quadrilateral. When the push rod 31 moves along the first track groove 112, the swing arm 32 rotates around the third end 323 of the swing arm, and the second end 332 of the rear pull rod moves between the second track groove first position a and the second track groove second position b of the second track groove 111, so that the first end and the second end of the handle 2 can simultaneously approach or move away from the opening of the accommodating groove 11, so that the two ends of the handle 2 can simultaneously extend out of the opening of the accommodating groove 11, ensuring that the handle 2 has a larger hand operation space when it needs to be pulled.

[0057] At the same time, since the push rod 31 is connected to the output shaft of the actuator assembly 4 and the push rod 31 moves along the first track groove 112, it can be limited by the first track groove 112, thereby improving the stability of the push rod 31 during movement and self-locking. The first end 321 of the swing arm 32 is connected to the push rod 31, and the third end 323 of the swing arm is rotatably connected to the handle base 1, thereby improving the stability of the swing arm 32 during movement and self-locking. The second end 332 of the rear pull rod 33 moves along the second track groove 111 and can be limited by the second track groove 111. At the same time, the rear pull rod 33 is also connected to the push rod 31, thereby improving the stability of the rear pull rod 33 during movement and self-locking.

[0058] Since the stability of the push rod 31, the swing arm 32 and the rear pull rod 33 during movement and self-locking is improved, the stability of the handle 2 connected to the swing arm 32 and the rear pull rod 33 during movement and self-locking can be improved.

[0059] In one example, reference Figures 4 to 6 As shown, the actuator assembly 4 includes an actuator body 41, a tension spring 42 and a first return torsion spring 43. The output shaft of the actuator body 41 is connected to the push rod 31, for example Figure 4As shown, the output shaft of the actuator body 41 can be connected to the push rod first end 311 of the push rod 31 .

[0060] The first return torsion spring 43 is connected between the swing arm 32 and the handle base 1 or the handle 2, so that the first end 311 of the push rod abuts against the first end 321 of the swing arm. For example, the first return torsion spring 43 can be connected between the swing arm 32 and the handle base 1, or between the swing arm 32 and the handle 2.

[0061] The tension spring 42 is connected between the push rod 31 and the rear rod second end 332, so that the push rod second end 312 abuts against the rear rod second end 332. For example, the push rod second end 312 of the push rod 31 has a U-shaped groove facing the rear rod second end 332 and used to accommodate the tension spring 42, and the two ends of the tension spring 42 can be fixedly connected to the bottom of the U-shaped groove and the rear rod second end 332, respectively.

[0062] The connection between the output shaft of the actuator body 41 and the push rod 31 may be a fixed connection or a rotational connection. For example, the output shaft of the actuator body 41 and the push rod 31 may be fixedly connected together through a coupling, or may be connected by a shaft pin to achieve a relatively rotatable connection. In this embodiment, the connection method between the output shaft of the actuator body 41 and the push rod 31 is not limited, as long as the output shaft of the actuator body 41 can push or pull the push rod 31 to move along the first track groove 112.

[0063] As described above, when the actuator body 41 drives the push rod 31 to move along the first track 112 toward the first direction 1121, the first end 311 of the push rod can push the swing arm 32 to rotate positively around the third end 323 of the swing arm, so that the first reset torsion spring 43 is twisted positively, and the second end 322 of the swing arm drives the first end of the handle to move toward the outside of the opening of the receiving groove 11, and can also positively pull the second end of the handle and the first end 331 of the rear rod. At the same time, because the second end 312 of the push rod can push the second end 332 of the rear rod to move from the first position a of the second track groove 111 toward the second position b, the rear rod 33 can positively rotate around the first end 331 of the rear rod, and then drive the second end of the handle to move toward the outside of the opening of the receiving groove 11. As a result, the first end and the second end of the handle 2 can simultaneously extend out of the receiving groove 11 from the opening of the receiving groove 11.

[0064] When the actuator body 41 drives the push rod 31 to move along the first track 112 toward the second direction 1122, in order to keep the first end 311 of the push rod against the first end 321 of the swing arm, the first return torsion spring 43 reversely twists, driving the swing arm 32 to rotate in the opposite direction around the third end 323 of the swing arm, so that the second end 322 of the swing arm drives the first end of the handle to move toward the opening of the receiving groove 11, and can also push the second end of the handle and the first end 331 of the rear rod in the opposite direction. At the same time, in order to keep the second end 312 of the push rod against the second end 332 of the rear rod, the tension spring 42 pulls the second end 332 of the rear rod to move from the second position b of the second track groove 111 toward the first position a, so that the rear rod 33 can rotate in the opposite direction around the first end 331 of the rear rod, and then drive the second end of the handle to move toward the opening of the receiving groove 11. In this way, the first end and the second end of the handle 2 can be retracted from the opening of the receiving groove 11 into the receiving groove 11 at the same time.

[0065] In this way, since the first return torsion spring 43 and the tension spring 42 serve as the force-applying mechanism when the handle 2 is retracted into the receiving groove 11, it is possible to avoid excessive rigidity from pinching the hand when the handle 2 is retracted, while also ensuring the stability of the handle 2 after it extends out of the opening of the receiving groove 11 and during the process of being retracted into the receiving groove 11.

[0066] In one example, in order to enable the rear rod second end 332 to move along the second track groove 111, the flat-out hidden door handle further includes a rear rod first shaft pin 3321, the rear rod second end 332 has a first mounting hole, and the rear rod first shaft pin 3321 passes through the first mounting hole and extends into the second track groove 111. Thus, the swing arm second end 322 can move along the second track groove 111 through the rear rod first shaft pin 3321.

[0067] In one example, in order to realize the relatively rotatable connection between the second end 322 of the swing arm and the first end of the handle and between the second end of the handle and the first end 331 of the rear pull rod, the flat-out hidden door handle also includes a first axis pin 3221 of the swing arm and a second axis pin of the rear pull rod, the second end 322 of the swing arm and the first end of the handle have corresponding second mounting holes, the second end of the handle and the first end 331 of the rear pull rod have corresponding third mounting holes, the first axis pin 3221 of the swing arm passes through the second mounting hole of the second end 322 of the swing arm and the second mounting hole of the first end of the handle in sequence, and the second axis pin of the rear pull rod passes through the third mounting hole of the second end of the handle and the third mounting hole of the first end 331 of the rear pull rod in sequence. Thus, the first axis pin 3221 of the swing arm and the second axis pin of the rear pull rod can realize the relatively rotatable connection between the second end 322 of the swing arm and the first end of the handle and between the second end of the handle and the first end 331 of the rear pull rod.

[0068] In one example, in order to realize the rotational connection between the third end 323 of the swing arm and the handle base 1, the flat-out hidden door handle also includes a second swing arm axle pin 3231, and the third end 323 of the swing arm has a corresponding fourth mounting hole, and the second swing arm axle pin 3231 penetrates the fourth mounting hole of the third end 323 of the swing arm and extends into the third mounting hole of the handle base 1. Thus, the third end 323 of the swing arm can be rotatably connected to the handle base 1 through the second swing arm axle pin 3231.

[0069] In one example, the first return torsion spring 43 may include two, one of which may be connected between the swing arm 32 and the handle base 1, and the other may be connected between the swing arm 32 and the handle 2. Figure 6 As shown, one first return torsion spring 43 is sleeved on the first shaft pin 3221 of the swing arm, and the first return torsion spring 43 is respectively in contact with the third end 323 of the swing arm and the handle base 1, and another first return torsion spring 43 is sleeved on the second shaft pin 3231 of the swing arm, and the first return torsion spring 43 is respectively in contact with the second end 322 of the swing arm and the handle 2. In this way, the handle 2 can be reset more stably, and at the same time, since the force required for the reset is shared by the two first return torsion springs 43, the service life of the first return torsion spring 43 can be increased.

[0070] In one example, in order to increase the smoothness when the first end 311 of the push rod pushes the first end 321 of the swing arm and improve the stability when the handle 2 is extended, accordingly, reference Figure 4 As shown, the first end 311 of the push rod has an inclined surface 3111 facing the first end 321 of the swing arm and the opening of the accommodating groove 11 , and the inclined surface 3111 is used to abut against the first end 321 of the swing arm.

[0071] For example, the inclined surface 3111 may be Figure 4 The plane shown is a plane, and it can also be a curved surface. However, compared with the inclined surface 3111 being a curved surface, the inclined surface 3111 being a plane can better increase the smoothness when the push rod first end 311 pushes the swing arm first end 321, and improve the stability of the handle 2 when it is extended.

[0072] In one example, reference Fig.10 Combined with Fig.11 As shown, when the rear pull rod second end 332 moves from the second track groove first position a to the second track groove second position b, the handle 2 extends out from the receiving groove 11, and the second track groove second position b is closer to the opening of the receiving groove 11 than the second track groove first position a.

[0073] Since the second position b of the second trajectory groove is closer to the opening of the accommodating groove 11 than the first position a of the second trajectory groove, the rear pull rod 33 can be allowed to have a shorter length. On the one hand, it can reduce the space occupied by the rear pull rod 33, thereby allowing the accommodating groove 11 to be smaller. On the other hand, it can improve the stability of the rear pull rod 33 during movement.

[0074] In one example, reference Fig.11 Combined with Fig.10 As shown, the second track groove 111 gradually approaches the opening of the receiving groove 11 from the second track groove first position a to the second track groove second position b. In this way, the movement of the rear pull rod second end 332 between the first position a and the second position b is more stable.

[0075] In one example, in order to open the door by pulling the handle 2 after the handle 2 extends out of the receiving groove 11, the flat-out hidden door handle further includes a control rod 6 and a door opening pull line 7. The control rod 6 is located in the receiving groove 11, and the first end 61 of the control rod 6 is rotatably connected to the handle base 1. For example, the flat-out hidden door handle further includes a control rod axle pin 611, and the first end 61 of the control rod and the handle base 1 have corresponding fifth mounting holes, and the control rod axle pin 611 passes through the fifth mounting hole of the first end 61 of the control rod and extends into the fifth mounting hole of the handle base 1. Thus, the first end 61 of the control rod is rotatably connected to the handle base 1 through the control rod axle pin 611.

[0076] The control rod 6 has a third track groove 62, and the third track groove 62 can overlap with the second track groove 111 from the second track groove first position a to the second track groove second position b. Figure 8 , Fig. 9 and Fig.11 As shown, when the handle 2 is located in the receiving groove 11 , the portion between the second track groove first position a and the second track groove second position b overlaps with the portion between the third track groove first position d and the third track groove second position e of the third track groove 62 .

[0077] The third track groove 62 is used for the second end 332 of the rear pull rod to move, for example Fig. 9 As shown, the first axle pin 3321 of the rear pull rod can also extend into the third track groove 62 .

[0078] Continue to refer Fig.11 As shown, the second track groove 111 further has a second track groove third position c, which is located at one end of the second track groove second position b away from the second track groove first position a, and the second track groove third position c is closer to the opening of the accommodating groove 11 than the second track groove second position b. For example, the trajectory of the second track groove 111 between the second track groove second position b and the second track groove third position c is along an arc trajectory with the first end 61 of the control rod as the arc center.

[0079] Continue to refer Figure 8 As shown, the two ends of the door outer opening wire 7 are fixedly connected to the control rod 6 and the door lock respectively. For example, one end of the door outer opening wire 7 is fixedly connected to the end of the control rod 6 away from the third track groove 62.

[0080] From the above, reference Figure 8 , Fig. 9 , Fig.11 and Fig.12 As shown, when the first axis pin 3321 of the rear pull rod reaches the second position b of the second track groove from the first position a of the second track groove, the first axis pin 3321 of the rear pull rod also reaches the second position e of the third track groove from the first position d of the third track groove, and the handle 2 extends from the accommodating groove 11.

[0081] When the first axis pin 3321 of the rear rod reaches the second position b of the second track groove, the rear rod 33 is pulled by pulling the handle 2, so that the second end 332 of the rear rod continues to move along the second track groove 111 toward the third position c of the second track groove. At this time, since the second end 332 of the rear rod has reached the fifth position e of the third track groove, the second end 332 of the rear rod will drive the control rod 6, so that the control rod 6 rotates positively around the axis pin 611 of the control rod, and the part between the first position a of the second track groove and the second position b of the second track groove overlaps with the part between the first position d of the third track groove and the second position e of the third track groove 62, thereby pulling the door outer opening cable 7, and then opening the door. At this time, the second end 332 of the rear rod will be separated from the second end 312 of the push rod, and the tension spring 42 will be stretched.

[0082] In one example, in order to enable the control rod 6 to be reset, the flat-out hidden door handle also includes a second reset torsion spring 8, which is connected between the control rod 6 and the handle base 1. For example, the second reset torsion spring 8 is sleeved on the control rod shaft pin 611, and the second reset torsion spring 8 is respectively abutted against the control rod 6 and the handle base 1, so that the third track groove 62 can overlap with the second track groove 111 from the second track groove first position a to the second track groove second position b.

[0083] As described above, when the handle 2 is released, the tension spring 42 is reset, pulling the second end 332 of the rear pull rod against the second end 312 of the push rod, and at this time, the first axis pin 3321 of the rear pull rod is located at the second track groove second position b, and may be located at the third track groove first position d of the third track groove 62. At this time, the third track groove 62 may not overlap with the second track groove 111 from the second track groove first position a to the second track groove second position b, and the control rod 6 has not been completely reset. The second reset torsion spring 8 can make the control rod 6 continue to rotate in the opposite direction around the control rod axis pin 611 until the third track groove 62 can overlap with the second track groove 111 from the second track groove first position a to the second track groove second position b.

[0084] In one example, the first track groove 112 is a straight line, and the first track groove 112 is parallel to the first outer surface of the door body. For example, a guide block 313 is fixedly connected to the push rod 31, and the guide block 313 is slidably connected to the first track groove 112. Since the first track groove 112 has a straight track, the moving track of the push rod 31 is simple and stable, which is conducive to improving the stability of the handle 2 when it is extended out of the door.

[0085] In the embodiment disclosed herein, the push rod 31, the swing arm 32, the handle 2 and the rear pull rod 33 are connected in sequence to form a quadrilateral. When the push rod 31 moves along the first track groove 112, the swing arm 32 rotates around the third end 323 of the swing arm, and the second end 332 of the rear pull rod moves between the second track groove first position a and the second track groove second position b of the second track groove 111, so that the first end and the second end of the handle 2 can simultaneously approach or move away from the opening of the accommodating groove 11, so that the two ends of the handle 2 can simultaneously extend out of the opening of the accommodating groove 11, ensuring that the handle 2 has a larger hand operation space when it needs to be pulled.

[0086] At the same time, since the push rod 31 is connected to the output shaft of the actuator assembly 4 and the push rod 31 moves along the first track groove 112, it can be limited by the first track groove 112, thereby improving the stability of the push rod 31 during movement and self-locking. The first end 321 of the swing arm 32 is connected to the push rod 31, and the third end 323 of the swing arm is rotatably connected to the handle base 1, thereby improving the stability of the swing arm 32 during movement and self-locking. The second end 332 of the rear pull rod 33 moves along the second track groove 111 and can be limited by the second track groove 111. At the same time, the rear pull rod 33 is also connected to the push rod 31, thereby improving the stability of the rear pull rod 33 during movement and self-locking.

[0087] Since the stability of the push rod 31, the swing arm 32 and the rear pull rod 33 during movement and self-locking is improved, the stability of the handle 2 connected to the swing arm 32 and the rear pull rod 33 during movement and self-locking can be improved.

[0088] The disclosed embodiment also provides a vehicle door, which includes a vehicle door body and a flat-out hidden door handle as any one of the first aspects, and a handle base 1 is installed on the vehicle door body. For example, the handle base 1 can be fixedly connected to the vehicle door body by screws, bolts, etc.

[0089] In the embodiment disclosed herein, the push rod 31, the swing arm 32, the handle 2 and the rear pull rod 33 are connected in sequence to form a quadrilateral. When the push rod 31 moves along the first track groove 112, the swing arm 32 rotates around the third end 323 of the swing arm, and the second end 332 of the rear pull rod moves between the second track groove first position a and the second track groove second position b of the second track groove 111, so that the first end and the second end of the handle 2 can simultaneously approach or move away from the opening of the accommodating groove 11, so that the two ends of the handle 2 can simultaneously extend out of the opening of the accommodating groove 11, ensuring that the handle 2 has a larger hand operation space when it needs to be pulled.

[0090] At the same time, since the push rod 31 is connected to the output shaft of the actuator assembly 4 and the push rod 31 moves along the first track groove 112, it can be limited by the first track groove 112, thereby improving the stability of the push rod 31 during movement and self-locking. The first end 321 of the swing arm 32 is connected to the push rod 31, and the third end 323 of the swing arm is rotatably connected to the handle base 1, thereby improving the stability of the swing arm 32 during movement and self-locking. The second end 332 of the rear pull rod 33 moves along the second track groove 111 and can be limited by the second track groove 111. At the same time, the rear pull rod 33 is also connected to the push rod 31, thereby improving the stability of the rear pull rod 33 during movement and self-locking.

[0091] Since the stability of the push rod 31, the swing arm 32 and the rear pull rod 33 during movement and self-locking is improved, the stability of the handle 2 connected to the swing arm 32 and the rear pull rod 33 during movement and self-locking can be improved.

[0092] An embodiment of the present disclosure further provides a vehicle, which includes the vehicle door as described in the second aspect.

[0093] In the embodiment disclosed herein, the push rod 31, the swing arm 32, the handle 2 and the rear pull rod 33 are connected in sequence to form a quadrilateral. When the push rod 31 moves along the first track groove 112, the swing arm 32 rotates around the third end 323 of the swing arm, and the second end 332 of the rear pull rod moves between the second track groove first position a and the second track groove second position b of the second track groove 111, so that the first end and the second end of the handle 2 can simultaneously approach or move away from the opening of the accommodating groove 11, so that the two ends of the handle 2 can simultaneously extend out of the opening of the accommodating groove 11, ensuring that the handle 2 has a larger hand operation space when it needs to be pulled.

[0094] At the same time, since the push rod 31 is connected to the output shaft of the actuator assembly 4 and the push rod 31 moves along the first track groove 112, it can be limited by the first track groove 112, thereby improving the stability of the push rod 31 during movement and self-locking. The first end 321 of the swing arm 32 is connected to the push rod 31, and the third end 323 of the swing arm is rotatably connected to the handle base 1, thereby improving the stability of the swing arm 32 during movement and self-locking. The second end 332 of the rear pull rod 33 moves along the second track groove 111 and can be limited by the second track groove 111. At the same time, the rear pull rod 33 is also connected to the push rod 31, thereby improving the stability of the rear pull rod 33 during movement and self-locking.

[0095] Since the stability of the push rod 31, the swing arm 32 and the rear pull rod 33 during movement and self-locking is improved, the stability of the handle 2 connected to the swing arm 32 and the rear pull rod 33 during movement and self-locking can be improved.
