Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a door handle structure and a vehicle. Background Art

[0002] At present, many door handles on vehicles are hidden handles, such as outward-turning door handles and inward-turning door handles. Both door handles can be embedded in the door and are roughly flush with the outer surface of the door when not needed, so as to form a hidden handle appearance. When opening the door, the outward-turning door handle turns outward and the inward-turning door handle turns inward, and then the operator pulls the outward-turning door handle or presses the inward-turning door handle to open the door.

[0003] However, the outward-flipping door handle is in a cantilevered state when it is turned outward to open, which requires a high strength of the door handle, is difficult to design and process, and has a high cost. The inward-flipping door handle needs to be turned inward and downward, which makes it impossible to set a mechanical lock core, that is, the inward-flipping door handle cannot be integrated with a mechanical lock core.

[0009] In a specific embodiment, the shift rod is provided with an opening, and an extension rod segment is provided at one end of the transmission rod and the second gear for rotation connection, and the extension rod segment is inserted into the opening. The shift rod rotates with the motor to shift the extension rod segment, thereby driving the transmission rod to rotate around the first axis.

[0010] In a specific embodiment, a hook portion extending toward the outer side of the vehicle door is further provided at the end of the extension rod section, and the hook portion passes outward through the opening.

[0011] In a specific embodiment, the flip cover is provided with two second gears along the left and right directions, the base is correspondingly provided with two first gears, and the transmission part correspondingly includes two transmission rods, one of which is provided with the extension rod segment.

In this way, a mechanical lock core can be arranged on the side of the mechanical handle, that is, the door handle structure can be integrated with a mechanical lock core to realize emergency manual unlocking.

[0056] In order to enable those skilled in the art to better understand the scheme of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0057] Please refer to Figure 1-4 , Figure 1 This is a schematic diagram of a door handle structure 200 installed on a vehicle door 100 in an embodiment of the present application; Figure 2 for Figure 1A schematic diagram of the middle door handle structure 200 after the flap 3 is opened, with a dotted frame indicating the hidden position of the flap 3 after opening, and in fact, the flap 3 cannot be observed from the outside of the vehicle door; Figure 3 for Figure 2 Schematic diagram from another perspective; Figure 4 Schematic diagram of a door handle structure 200 in an embodiment of the present application.

[0058] like Figure 2 As shown, the vehicle door 100 is provided with a door lock 400 for locking the vehicle door 100 and the vehicle body. The vehicle door 100 is also provided with a handle operating opening 100a. The handle operating opening 100a is an opening opened in the vehicle door 100 and passes through the vehicle door 100 along the inside and outside. The main structure of the door handle structure 200 in this embodiment is arranged on the inner side of the handle operating opening 100a, that is, it is arranged on the side of the vehicle door 100 close to the vehicle cabin. The door handle structure 200 includes a mechanical handle 8 for opening the vehicle door 100 and a mechanical lock core 6 for physically unlocking the vehicle door. After the vehicle receives a control signal for opening the door (the control signal can be a remote control key or a mobile phone Bluetooth signal, etc.), the electronic control system will control the unlocking of the first lock of the door lock 400. At this time, the operator operates the mechanical handle 8 to unlock the second lock of the door lock 400. The structural principle of the door lock 400 and the process of unlocking the mechanical handle 8 can be understood with reference to the prior art and will not be expanded here.

[0059] In this embodiment, the mechanical handle 8 is located inside the handle operation opening 100a. Figure 3 As shown, the mechanical handle 8 is located below the handle operating port 100a. The mechanical handle 8 does not need to extend outward from the handle operating port 100a during operation. After the mechanical lock core 6 is opened by the flip cover 3, the key hole 6a of the mechanical lock core 6 is exposed at the handle operating port 100a, so that the operator can insert a physical key into the key hole 6a to unlock the door.

[0060] It should be emphasized that the door handle structure 200 in this embodiment also includes a flip cover 3. Figure 1 , 2 Understand, Flip 3 in Figure 1 The flap 3 is in the first position, at which time the flap 3 covers the handle operation opening 100a, and the flap 3 can be substantially flush with the outer surface of the vehicle door 100, and can also be made of the same material and color as the outer surface of the vehicle door 100. In this way, when the flap 3 covers the handle operation opening 100a, it can be hidden from the outside of the vehicle, that is, a hidden handle is formed. Figure 1 The position shown in FIG. 1 is turned upward and inward along the direction indicated by the dotted arrow to the inner side of the handle operation opening 100a so as to be located at Figure 2The position indicated by the dotted line frame is shown in FIG. 1 . When viewed from the front of the vehicle door 100, the flip cover 3 is hidden inside the vehicle door 100. The flip cover 3 is in Figure 2 In the second position shown, the handle operation port 100a is opened. Figure 3 As shown, the operator can now open or close the door through the handle operation opening 100a on the mechanical handle 8. As can be seen from the above description, in the door handle structure 200 of this embodiment, only the flip cover 3 can be flipped to the outside of the handle operation opening 100a to cover the handle operation opening 100a, and the other components of the door handle structure 200 are all arranged on the inside of the handle operation opening 100a.

[0061] The specific structure and flipping implementation method of the flip cover 3 in this embodiment will be described in detail below.

[0062] like Figure 5-9 As shown, Figure 5 for Figure 4 A rear view of the middle door handle structure 200, i.e., a perspective viewed from the inside of the vehicle door 100; Figure 6 for Figure 4 An exploded view of the middle door handle structure 200; Figure 7 for Figure 6 A schematic diagram of the middle flip cover 3; Figure 8 for Figure 6 A schematic diagram of the middle lever 4; Fig. 9 for Figure 6 A schematic diagram of the middle transmission part 5; Fig.10 for Figure 5 Schematic diagram of the meshing of the first gear 11 and the second gear 31.

[0063] The door handle structure 200 in this embodiment includes a base 1. Figure 6 The door handle structure 200 is roughly in the shape of a shell with an opening toward the inner surface of the vehicle door 100. Other components of the door handle structure 200 are mounted on the base 1. The base 1 is mounted to the vehicle door 100. The base 1 can be fixed to the vehicle door 100 by fastener connection or welding, and the specific connection method is not limited here.

[0064] In addition, if Figure 5 , 7As shown in FIG. 10 , the side of the base 1 facing the inner surface of the vehicle door 100 is defined as the outer side, and the opposite side is defined as the inner side. The outer side of the base 1 is roughly formed with a second accommodating chamber 1a and a first accommodating chamber 1b. The first accommodating chamber 1b is located below the second accommodating chamber 1a. The base 1 is provided with a first gear 11, which is fixed on the base 1. The first gear 11 is arranged on the inner side of the base 1, specifically on the side wall portion 13 forming the first accommodating chamber 1b. The flip cover 3 is provided with a second gear 31, which includes a flip cover body 33, and the flip cover body 33 is located on the outer side of the base 1. The second gear 31 of the flip cover 3 can be located on the inner side of the base 1, so that the first gear 11 and the second gear 31 always maintain a meshing connection relationship.

[0065] like Figure 6 As shown, the middle part of the lower part of the base 1 is the first accommodating chamber 1b, and both sides of the top of the first accommodating chamber 1b are provided with a partition wall 12, and the partition wall 12 serves as the bottom wall of the second accommodating chamber 1a. The first partition wall 12 can be provided with a through hole 12a, and the mechanical lock core 6 is inserted at the position of the through hole 12a, and the key hole 6a is exposed in the through hole 12a. The partition wall 12 is provided with a slot 12b that passes through from top to bottom, and the slot 12b is a long slot extending inward and outward directions of the vehicle door 100, as shown in FIG. Figure 7 As shown, a connecting rod 32 is provided inside the flip cover 3. The connecting rod 32 is roughly L-shaped. One end of the connecting rod 32 is connected to the flip cover body 33, and the other end is connected to the second gear 31. The connecting rod 32 and the second gear 31 are an integrated structure, which is separately connected to the flip cover body 3. It can be seen that the connecting rod 32, the second gear 31 and the flip cover body 33 can be separately or integrally arranged. Figure 4 , the connecting rod 32 can pass through the slot 12b from the outside of the base 1, so that the second gear 31 is located on the inside of the base 1 to mesh with the first gear 11 inside, that is, the setting of the connecting rod 32 is conducive to the inside and outside arrangement of the flip cover body 33 and the first gear 31, and the setting of the connecting rod 32 should ensure that it does not interfere with the partition wall 12 during the flipping process. In this way, the first gear 11 and the second gear 31 are both located on the inside of the base 1, which is convenient for protecting the gear assembly and maintaining a relatively neat appearance.

[0066] Look again Fig. 9 The door handle structure 200 in this embodiment further includes a transmission part 5, which includes a transmission rod 53, a first rotating shaft 51 and a second rotating shaft (not shown in the figure), only the second axis X2 of the second rotating shaft is shown, and the axis of the first rotating shaft 51 is the first axis X1. One end of the transmission rod 53 is rotatably connected to the base 1 through the first rotating shaft 51. Figure 5 As shown, the other end of the transmission rod 53 is rotationally connected to the second gear 31 via a second rotating shaft, and the first axis X1 and the second axis X2 are parallel and substantially extend along the front-rear direction of the vehicle.

[0067] Look again Figure 4 , 6 The door handle structure 200 in this embodiment also includes a motor 2, which is also installed on the base 1. As mentioned above, the base 1 is provided with a second accommodating chamber 1a, and the motor 2 is installed in the second accommodating chamber 1a to better position and protect the motor 2. The middle of the bottom of the first accommodating chamber 1a is an opening, corresponding to the top of the first accommodating chamber 1b, and the middle of the bottom of the first accommodating chamber 1a is a partition wall 12 on both sides. When receiving a control signal for opening or closing the door, the motor 2 can start working, that is, the motor 2 is connected to a terminal device such as a remote control key or a mobile phone by signal.

[0068] Look again Figure 8 The door handle structure 200 in this embodiment also includes a lever 4, which includes a head 41 and a rod 42. The head 41 is roughly cylindrical, and the rod 42 is connected to one radial side of the head 41. The head 41 is provided with an axial hole 41a, and the rod 42 is provided with an opening 42a. The rod 42 is divided into two thin rods 422 and a cross rod 421 by the opening 42a. One end of each thin rod 422 is connected to the head 41, and the other end of each thin rod 422 is connected to the cross rod 421. In this way, the cross rod 421, the two thin rods 422 and one side of the head 41 enclose a long strip of opening 42a.

[0069] Please continue to combine Figure 4 , and refer to Fig.11 understand, Fig.11 for Figure 4 Schematic diagram of the coordinated position of the middle lever 4 and the motor 2.

[0070] The motor 2 has an output shaft 21, and the output shaft 21 of the motor 2 is inserted into the shaft hole 41a of the head 41 of the lever 4. The side wall of the output shaft 21 can have a flat surface, and the cross section is roughly D-shaped. The shaft hole 41a can also have a flat hole wall that matches the flat surface, so that the output shaft 21 and the shaft hole 41a are anti-rotationally matched, and when the output shaft 21 rotates, it can drive the head 41 of the lever 4 to rotate. It can be seen that there are many ways to connect the output shaft 21 and the lever 4 in transmission. For example, the two can also be key-matched. For another example, the shaft hole 41a of the lever 4 is set to a non-circular hole such as a square hole, an elliptical hole, etc. The shape of the output shaft 21 is adapted to the shaft hole 41a, and the purpose of transmission connection can also be achieved. The rod portion 42 of the lever 4 is provided with an opening 42a, Fig. 9 The transmission rod 53 of the middle transmission part 5 is connected to one end of the second gear 31 for rotation. The extension rod section 531 is further connected to the transmission rod 53. The extension rod section 531 and the transmission rod 53 can be an integral structure or a separate fixed connection. The top of the extension rod section 531 is also provided with a hook portion 5311 extending toward the outside of the vehicle door 100. Fig.11The extension rod segment 531 of the transmission rod 53 extends out from the slot 12b and penetrates into the opening 42b of the lever 4, wherein the hook portion 5311 of the extension rod segment 5311 passes through the opening 42b to the outside, so that when the output shaft 21 of the motor 2 rotates, the lever 4 can be driven to rotate, and the cross bar portion 421 of the lever 4 can move the extension rod segment 531 to drive the transmission rod 53 to rotate around the first axis X1.

[0071] It can be seen that the extended rod section 531 and the lever 4 cooperate with each other to realize the toggle transmission, and the hook portion 5311 is further provided because as the extended rod section 531 and the lever 4 rotate, the extended rod section 531 and the opening 42a of the lever 4 gradually separate, and the hook portion 5311 can ensure better contact and cooperation with the lever 4, which can be combined with Fig.15 It is understood that after the flip cover 3 is fully opened, the extension rod section 531 is no longer located in the opening 42 a of the lever 4 , while the hook portion 5311 is still inserted into the opening 42 a .

[0072] Please continue to combine Figure 12-16 understand, Fig.12 It is a schematic diagram of the flip cover 3 of the door handle structure 200 covering the handle operation opening 100a of the vehicle door 100 in the embodiment of the present application; Fig.13 for Fig.12 Middle AA section view; Fig.14 This is a schematic diagram of the door handle structure 200 when the flip cover 3 is fully opened in the embodiment of the present application; Fig.15 for Fig.14 The BB section view shows that the flip cover 3 is flipped to the second position. Fig.15 The dotted line in the figure indicates the dynamic trajectory of the movement of the flip cover 3; Fig.16 for Fig.14 CC section view.

[0073] like Fig.13 As shown, the output shaft 21 of the motor 2 is Figure 2 The second gear 31 is meshed with the first gear 11, so the second gear 31 will rotate along the second axis X2 along the first gear 11, that is, the second gear 31 is also equivalent to rotating on its own. It can be seen that the center of the circle corresponding to the first gear 11 and the first axis X1 should overlap. In this way, the second gear 31 will drive the flip cover 3 to flip inward and upward during the rotation process. Fig.15 The flipping motion trajectory of the flip cover 3 is shown in FIG. 1 , where the flip cover 3 is sealed on the outside of the handle operating opening 100a, gradually moves upward and inward, and finally stops above the inside of the handle operating opening 100a. At this time, the flip cover 3 is in the second position, and the handle operating opening 100a is fully opened.

[0074] When the flip cover 3 is opened, Figure 3 As shown, the operator can operate the mechanical handle 8 from the handle operation opening 100 a to open the vehicle door 100 .

[0075] Compared with the external hanging door handle that opens outward in the background technology, in the embodiment of the present application, the mechanical handle 8 is no longer used to cover the handle operation opening 100a of the vehicle door 100, and the concealing function of covering the handle operation opening 100a is realized by the flip cover 3 that is separately arranged from the mechanical handle 8, and the flip cover 3 is arranged to flip inward and upward, so that after the flip cover 3 opens the handle operation opening 100a, the mechanical handle 8 can be operated, and the mechanical handle 8 does not need to be arranged as a cantilever structure, the strength requirement is lower, and the processing technology is simpler. Moreover, compared with the inward flip door handle in the background technology, in the present embodiment, the mechanical handle 8 that blocks the handle operation opening 100a and the unlocking mechanical handle 8 are separately arranged, and the flip cover 3 can be flipped upward and inward, so that the position of the door lock 400 below the inner side of the handle operation opening 100a will not be blocked, so that the mechanical lock core 6 can be arranged beside the mechanical handle, that is, the door handle structure 200 can be integrated with the mechanical lock core 6.

[0076] From the above description, it can be seen that the door handle structure 200 in the embodiment of the present application separately sets the flip cover 3 and the mechanical handle 8 that block the handle operating port 100a. The flip cover 3 can block the handle operating port 100a. When the door needs to be opened, the flip cover 3 is flipped inward and upward to open the handle operating port 100a and operate the mechanical handle 8. Therefore, it is only necessary to set an electric drive unit such as a motor 2 to drive the flip cover 3 to flip inward. For example, the motor 2 can directly drive the flip cover 3 to flip inward and upward.

[0077] In this embodiment, as mentioned above, the door handle structure 200 is provided with a transmission part 5 to drive the second gear 31 of the flip cover 3 to rotate around the first axis X1, and at the same time, the second gear 31 of the flip cover 3 can rotate around the second axis X2 along the first gear 11. Therefore, the motion trajectory of the flip cover 3 is actually determined by the combination of two motions, such as Fig.16As shown, if the mechanical lock core 6 is set too far from the door lock 400, a complex transmission mechanism needs to be set, which may cause physical unlocking to fail. Therefore, in order to realize physical unlocking of the door lock 400, the mechanical lock core 6 must be set close to the door lock 400. In this way, when the flip cover 3 covers the handle operating port 100a, the mechanical lock core 6 is set on the inner side of the flip cover 3, near the unlocking actuator 7 and the door lock 400. In this way, when the flip cover 3 is flipped inward and upward, it will be close to the mechanical lock core 6 and easily interfere with the mechanical lock core 6. As mentioned above, the setting position of the mechanical lock core 6 is limited, so it is difficult to avoid interference with the flip cover 3 during the flipping process by simply adjusting the position of the mechanical lock core 6. In this embodiment, the transmission part 5 and the cooperation of the first gear 11 and the second gear 31 are set, so that the movement trajectory of the flip cover 3 is formed by the combination of two rotation forms: rotation around the second axis X2 and revolution around the first axis X1. Fig.16 It can be seen that the movement trajectory of the flip cover 3 from the outside to the inside is not an arc path, but gradually deviates from the arc path upward and inward. In this way, the distance from the mechanical lock core 6 can be increased during the flip opening process to avoid interference with the mechanical lock core 6.

[0078] like Fig.16 As shown, the base 1 is provided with a partition wall portion 12 between the second accommodating chamber 1a and the first accommodating chamber 1b. The partition wall portion 12 can extend along the movement trajectory of the flip cover 3. In this way, the partition wall portion 12 can separate the flip cover 3 from the inner side of the base 1. In order to reduce friction, the partition wall portion 12 may not contact the flip cover 3.

[0079] Please continue to refer to Fig. 9 The transmission part 5 in this embodiment specifically includes two transmission rods 53, and the two transmission rods 53 are rotatably connected to the base 1 through the first rotating shaft 51. It can be known that the two transmission rods 53 can also be connected to the base 1 through a corresponding rotating shaft. In this embodiment, a first rotating shaft 51 is provided to connect the two transmission rods 53, which has a simpler structure and is easier to ensure coaxiality. The output shaft 21 of the motor 2 is only matched with one lever 4, so only one of the transmission rods 53 is provided with an extension rod section 531 to match the lever 4, and the other transmission rod 53 does not extend the extension rod section 531. Figure 7 As shown, the flip cover body 33 of the flip cover 3 is provided with two second gears 31 along the left-right direction, the left-right direction is the front-back direction of the vehicle, the two second gears 31 and the above-mentioned two transmission rods 53 are rotatably connected through a second rotating shaft, and similarly, the two second gears 31 are respectively connected to the two transmission rods 53 through a rotating shaft, and correspondingly, the base 1 is also provided with two first gears 11, which are respectively meshed with the two second gears 31 one by one. With such a configuration, the transmission part 5 is more stable in transmitting the flip cover 3, and the flip cover 3 is driven to rotate by the two second gears 31, and the rotation is stable and reliable.

[0080] Look again Figure 4 , 5 As described above, the base 1 in this embodiment is provided with a first accommodating chamber 1b, the first accommodating chamber 1b is below the second accommodating chamber 1a, the mechanical handle 8 can be located in the first accommodating chamber 1b, the two first gears 11 are respectively arranged on the two side wall portions 13 of the first accommodating chamber 1b, then the two transmission rods 53 can be located on the side wall portions 13 on the left and right sides of the first accommodating chamber 1b, specifically, they are arranged on the side of the side wall portion 13 away from the first accommodating chamber 1b, Figure 5 In the embodiment, supports 14 are arranged on the left and right sides of the lower inner side of the base 1, and the first rotating shaft 51 passes through the two supports 14. In this way, the first gear 11 and the second gear 31 for power transmission can be separated from the first accommodating cavity 1b and located on the inner side of the base 1. In this way, after the flip cover 3 is opened, the transmission part 5 and the first gear 11 are hidden on the inner side of the base 1, which plays a role in protecting and maintaining a neat appearance. The left and right directions of the first accommodating cavity 1b and the base 1 mentioned here are also the front and rear directions of the vehicle.

[0081] In this embodiment, the first gear 11 and the second gear 31 are both arc-shaped teeth, not complete circular gear structures, which are mainly arranged according to the flip stroke of the flip cover 3. The arrangement of the arc-shaped teeth can save space and reduce transmission interference.

[0082] In addition, the mechanical handle 8 in this embodiment is specifically a push-type handle.

[0083] For details, please refer to Figure 17-19 understand, Fig.17 It is a schematic diagram of the flip cover 3 of the door handle structure 200 covering the handle operation opening 100a of the vehicle door 100 in the embodiment of the present application; Fig.18 for Fig.17 Middle DD section view; Fig.19 for Fig.17 Middle EE section view; Fig. 20 It is a schematic diagram of the meshing of the third gear 81 of the mechanical handle 8 and the fourth gear 71 of the unlocking actuator 7 in the embodiment of the present application.

[0084] The mechanical handle 8 in this embodiment includes a handle body 82, on which a third gear 81 is disposed, and the unlocking actuator 7 of the vehicle door 100 is provided with a fourth gear 71, and the unlocking actuator 7 is connected to the cable 300 for unlocking the door lock 400. Fig.18 , 19As shown in FIG. 20 , the handle body 82 and the base 1 are rotationally connected via the third rotating shaft 83, the third gear 81 is also connected to the third rotating shaft 83, the unlocking actuator 7 and the base 1 are rotationally connected via the fourth rotating shaft 72, and the rotation axis is the fourth rotating axis X4. The third axis X3 of the third rotating shaft 83 is parallel to the fourth axis X4 of the fourth rotating shaft 72. When the handle body 82 is pressed downward, the handle body 82 rotates around the third axis X3 of the third rotating shaft 83, driving the third gear 81 to rotate clockwise around the third axis X3. When the third gear 81 rotates, it meshes with the fourth gear 71 for transmission, and can drive the fourth gear 71 to rotate counterclockwise around the fourth rotating axis X4. Fig. 20 In the process, the fourth gear 71 will drive the unlocking actuator 7 to rotate counterclockwise. The fourth gear 71 is set at one end of the unlocking actuator 7, and the other end of the unlocking actuator 7 is connected to the cable 300. When the unlocking actuator 7 rotates counterclockwise, the cable 300 can be pulled upward to unlock the door lock 400. The operator presses the handle body 82 and pulls the car door 100 outward at the same time to open the car door 100.

[0085] The unlocking actuator 7 is used to pull the cable 300 to unlock the door lock 400. The unlocking linkage between the cable 300 and the door lock 400 can be understood by referring to the prior art and will not be discussed in detail. The transmission method between the mechanical handle 8 and the unlocking actuator 7 is not limited to this, as long as the mechanical handle 8 can drive the unlocking actuator 7 to pull the cable 300. In this embodiment, the base 1 of the door handle structure 100 is also provided with a mounting portion 15, which is arranged at the lower end of one side of the main structure of the base 1, such as Figure 4 , 5 As shown, the unlocking actuator 7 is installed on the mounting portion 15 , and the unlocking actuator 7 is installed on the side of the mounting portion 15 away from the inner surface of the vehicle door 100 . Installing it at this position facilitates the unlocking operation of the door lock 400 .

[0086] It is worth noting that the door handle structure 200 in this embodiment can be manually operated when the motor 2 fails, such as when the motor 2 is damaged and the control signal cannot be sent. Specifically, the flip cover 3 is manually pushed inward and upward to flip over, exposing the key hole 6a of the mechanical lock core 6, and the mechanical lock core 6 is unlocked by a physical key to realize the emergency unlocking function. Figure 4 , 13As shown, the motor 2 in this embodiment drives the transmission part 5 to rotate around the first axis X1 through the lever 4. Specifically, the lever 4 is provided with an opening 42a, and the extension rod segment 531 at one end of the transmission rod 53 is inserted into the opening 42a. The extension rod segment 531 is pushed by the cross bar portion 421 of the lever 4. In the process of manually pushing the flip cover 3, the lever 4 does not move, and the extension rod segment 531 of the transmission part 5 can freely rotate around the first axis X1 in the opening 42a and gradually move away from the cross bar portion 421 of the lever 4. That is, although the lever 4 and the motor 2 cannot rotate, they will not interfere with the manual opening of the flip cover 3, and the flip cover 3 can be manually flipped.

[0087] It can be known that the lever 4 is mainly provided to drive the flip cover 3 to rotate toward the second position, and the lever 4 can drive the flip cover 3 to rotate. When the driving of the motor 2 fails, the lever 4 or the motor 2 cannot rotate but will not interfere with the flip cover 3 rotating automatically under manual action. Therefore, the lever 4 only needs to contact the extension rod segment 531 in a pushing direction, and is not limited to the above-mentioned rod portion 42 structure. For example, if the rod portion 42 is a solid structure, it can directly contact the extension rod segment 531 to be moved. However, the above-mentioned opening 42a is provided and the method of moving by the cross bar portion 421 is more reliable and is not easy to deviate from the extension rod segment 531. In addition, without considering the failure of the motor 2, it is obvious that the rotation of the transmission rod 53 does not need to be carried out by the movement of the lever 4. For example, the motor 2 can directly drive the transmission rod 53 to rotate around the first rotating shaft 51.

[0088] In addition, if Fig. 9 As shown, a return spring 52 is also provided on the first rotating shaft 51 of the transmission part 5. The return spring 52 is sleeved on the first rotating shaft 51. One end of the return spring 52 is connected to the transmission rod 53, and the other end can be connected to the base 1. When the flip cover 3 flips inward, the return spring 52 deforms to generate a restoring force. When the flip cover 3 needs to return to the first position of the cover handle operation port 100a, the restoring force of the return spring 52 can drive the transmission rod 53 to rotate back. When receiving a signal to close the door 100, the motor 2 reverses to Fig.15 The lever 4 will rotate clockwise, and the extension rod section 531 will rotate counterclockwise under the restoring force of the return spring 52. Alternatively, after the motor 2 fails and the flip cover 3 is manually flipped, when the manpower is withdrawn, the return spring 52 can also drive the transmission rod 53 and the extension rod section 531 to rotate counterclockwise, and then drive the flip cover 3 to flip back to the first position. However, it can be seen that when the lever 4 is not provided, the motor 2 can directly drive the transmission rod 53 to rotate counterclockwise and clockwise, and the return spring 52 can also be not provided.

[0089] Finally, you can combine Fig.21 , 22 To understand the overall solution of this embodiment, Fig.21This is a schematic diagram of the flipping process of the flip cover 3 in the embodiment of the present application, from left to right is the process of opening the flip cover 3, and from right to left is the process of closing the flip cover 3; Fig. 22 Schematic diagram of the unlocking process of the mechanical handle 8 in the embodiment of the present application.

[0090] like Fig.21 As shown in FIG. 1 , when the door 100 needs to be opened, the motor 2 receives an opening control signal, and the motor 2 rotates after receiving the control signal, and then drives the flip cover 3 to gradually flip inward and upward to the inner side of the door 100 through the lever 4 and the transmission part 5, and opens the handle operation opening 100a. After the flip cover 3 is opened, the operator can look down and see the mechanical handle 8 and the key hole 6a, and can press the mechanical handle 8 downward, as shown in FIG. Fig. 22 As shown, as the mechanical handle 8 is gradually pressed downward, the unlocking actuator 7 is gradually lifted up to pull the cable 300 under the meshing action of its fourth gear 71 and the third gear 81 of the mechanical handle 8, thereby unlocking the door lock 400. At this time, the operator can pull the vehicle door 100 outward while pressing the mechanical handle 8 to open the vehicle door 100.

[0091] After the operator closes the door 100, the motor 2 receives a closing control signal, the motor 2 reverses, and under the reset force of the return spring 52, the flip cover 3 moves along the Fig.21 The sequential movement from right to left means gradually turning outward and downward to re-close the handle operation opening 100a.
