Description

Technical Field

[0001] This invention relates to the field of vehicle technology, specifically to a door handle structure and a vehicle. Background Technology

[0002] Many vehicles now feature concealed door handles, such as outward-opening and inward-opening handles. Both types are embedded in the door and, when not in use, are roughly flush with the outer surface of the door, creating a hidden appearance. To open the door, outward-opening handles turn outwards, and inward-opening handles turn inwards. The operator then pulls the outward-opening handle or presses the inward-opening handle to open the door.

[0003] However, outward-opening door handles are in a cantilevered state when they turn outwards, which requires high strength and is more difficult to design and manufacture, resulting in higher costs. Inward-opening door handles need to turn inwards and downwards, which makes it impossible to install a mechanical lock cylinder. In other words, inward-opening door handles cannot integrate a mechanical lock cylinder. Summary of the Invention

[0004] To address the aforementioned technical problems, the purpose of this application is to provide a door handle structure and a vehicle, which has lower requirements for handle strength and can integrate a mechanical lock cylinder.

[0005] This application provides a door handle structure, including a base, a flip cover, and an electric drive unit. The base is installed on the inside of a vehicle door, and the electric drive unit is used to drive the flip cover to flip and switch between a first position and a second position. In the first position, the flip cover covers the handle operation opening of the vehicle door. In the second position, the flip cover rotates upward and inward toward the inside of the vehicle door to open the handle operation opening. The door handle structure also includes a mechanical handle and a mechanical lock cylinder, both of which are located inside the handle operation opening.

[0006] In one specific embodiment, the base is provided with a first gear, the flip cover is provided with a second gear, and the first gear and the second gear are engaged; the electric drive unit also drives the flip cover to rotate around a first axis.

[0007] In one specific embodiment, the door handle structure further includes a transmission part, the transmission part including a transmission rod, one end of the transmission rod being rotatably connected to the base about a first axis, the transmission rod being rotatably connected to a second gear about a second axis, the first axis and the second axis being parallel, and the electric drive part driving the transmission rod to rotate.

[0008] In one specific embodiment, the electric drive unit includes a motor, and the door handle structure further includes a lever, which is convexly connected to the output shaft of the motor; the lever is used to rotate the transmission rod to drive the flip cover to flip to the second position.

[0009] In one specific embodiment, the lever is provided with an opening, and one end of the transmission rod rotatably connected to the second gear is provided with an extension rod segment. The extension rod segment is inserted into the opening, and the lever rotates with the motor to actuate the extension rod segment, thereby driving the transmission rod to rotate around the first axis.

[0010] In one specific embodiment, the end of the extension rod segment is further provided with a hook extending outward toward the outside of the door, the hook passing outward through the opening.

[0011] In one specific embodiment, the flip cover is provided with two second gears in the left-right direction, the base is provided with two first gears, and the transmission part is provided with two transmission rods, one of which is provided with the extension rod segment.

[0012] In one specific embodiment, the base is provided with a first receiving cavity with an opening facing the inner surface of the vehicle door, the mechanical handle is located in the first receiving cavity, the wall portion surrounding the first receiving cavity includes left and right side wall portions, and the first gear is disposed on the side of the side wall portion away from the first receiving cavity.

[0013] In one specific embodiment, the base includes partition walls located on both sides of the top of the first accommodating cavity, the partition walls being provided with slots; the flip cover includes a flip cover body and a connecting rod, the connecting rod connecting the second gear and the flip cover body, the connecting rod passing through the slots to make the second gear and the first gear mesh.

[0014] In one specific embodiment, the base is provided with a second receiving cavity with an opening facing the inner surface of the door, the second receiving cavity being located above the first receiving cavity; the electric drive unit includes a motor, the door handle structure also includes a lever, the lever being operatively connected to the output shaft of the motor; one end of the transmission rod and the second gear being rotatably connected is provided with an extension rod segment, the extension rod segment passing upward through the slot and cooperating with the lever, the lever causing the extension rod segment to rotate to drive the flip cover to rotate to the second position.

[0015] In one embodiment, the transmission unit further includes a return spring that provides a restoring force to flip the flap to the first position.

[0016] In one specific embodiment, the transmission rod and the base are rotatably connected by a first rotating shaft, the return spring is sleeved on the first rotating shaft, one end of the return spring is connected to the transmission rod, and the other end is connected to the base.

[0017] The mechanical handle is provided with a third gear, and the mechanical handle and the base are rotatably connected around a third axis. The door handle structure also includes an unlocking actuator, which is provided with a fourth gear rotatably connected to the base around a fourth axis. The third gear and the fourth gear are engaged. When the mechanical handle is pressed down, it rotates around the third axis, and the fourth gear rotates, thereby driving the unlocking actuator to unlock.

[0018] This application also provides a vehicle, including a door, said door being provided with a door handle structure as described in any of the above claims.

[0019] Compared to the outward-opening, overhanging door handles in the prior art, the mechanical handle of this application no longer obstructs the door's operating opening. Instead, a separate flip cover conceals the operating opening. Furthermore, the flip cover is designed to flip inwards and upwards, allowing operation of the mechanical handle after the opening is opened. This eliminates the need for a cantilevered structure, reducing strength requirements and simplifying the manufacturing process. Moreover, unlike the inward-flipping door handles in the prior art, the separate design of the operating opening and the unlocking mechanical handle, along with the flip cover's upward and inward flipping, ensures that the door lock position below the inner side of the operating opening is not obstructed. This allows for the integration of a mechanical lock cylinder on the side of the mechanical handle, enabling emergency manual unlocking. Attached Figure Description

[0056] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] Please refer to Figure 1-4 , Figure 1 This is a schematic diagram of the door handle structure 200 installed on the vehicle door 100 in an embodiment of this application; Figure 2 for Figure 1A schematic diagram of the flip cover 3 of the middle door handle structure 200 after it is opened. The dotted box indicates the hidden position of the flip cover 3 after it is opened. In fact, the flip cover 3 cannot be observed from the outside of the car door. Figure 3 for Figure 2 A diagram from another perspective; Figure 4 This is a schematic diagram of the door handle structure 200 in an embodiment of this application.

[0058] like Figure 2 As shown, the car door 100 is equipped with a door lock 400 for locking the car door 100 and the car body. The car door 100 is also equipped with a handle operation port 100a, which is an opening in the car door 100 that runs through the car door 100 inside and out. In this embodiment, the main structure of the door handle structure 200 is located inside the handle operation port 100a, that is, on the side of the car door 100 closer to the cabin. The door handle structure 200 includes a mechanical handle 8 for opening the car door 100 and a mechanical lock cylinder 6 for physically unlocking the car door. After the vehicle receives a door opening control signal (the control signal can be a remote 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 unlocking process of the mechanical handle 8 can be understood with reference to the existing technology, and will not be elaborated here.

[0059] In this embodiment, the mechanical handle 8 is located inside the handle operation port 100a, specifically as follows: Figure 3 As shown, the mechanical handle 8 is located below the handle operation port 100a. During operation, the mechanical handle 8 does not need to extend outward from the handle operation port 100a. After the flip cover 3 is opened, the keyhole 6a of the mechanical lock cylinder 6 is exposed in the handle operation port 100a, so that the operator can use a physical key to insert into the keyhole 6a to unlock.

[0060] It should be emphasized that the door handle structure 200 in this embodiment also includes a flip cover 3, compared to Figure 1 , 2 I understand, the flip phone 3 is... Figure 1 In the first position, the flip cover 3 covers the handle operation opening 100a. The flip cover 3 can be roughly flush with the outer surface of the door 100, and can also be made of the same material and color as the outer surface of the door 100. Thus, when the flip cover 3 is placed over the handle operation opening 100a, it achieves a concealed effect from the outside of the vehicle, forming a hidden handle. The flip cover 3 of the door handle structure 200 can be viewed from... Figure 1 The position shown is rotated upwards and inwards in the direction indicated by the dotted arrow, until it is inside the handle operating port 100a, so as to be located... Figure 2As indicated by the dotted box, when viewed from the front of the door 100, the flip cover 3 is hidden inside the door 100. Figure 2 In the second position shown, open the handle operation port 100a, as indicated. Figure 3 As shown, the operator can open or close the door using the handle operation port 100a. As described above, in this embodiment, only the flip cover 3 of the door handle structure 200 can be flipped to the outside of the handle operation port 100a to cover it; all other components of the door handle structure 200 are located inside the handle operation port 100a.

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

[0062] like Figure 5-9 As shown, Figure 5 for Figure 4 Rear view of the center door handle structure 200, i.e., the view from the inside of the door 100 looking outward; Figure 6 for Figure 4 Exploded view of the 200mm diameter center door handle structure; Figure 7 for Figure 6 A schematic diagram of the middle flip cover 3; Figure 8 for Figure 6 A schematic diagram of the center lever 4; Figure 9 for Figure 6 Schematic diagram of the central transmission unit 5; Figure 10 for Figure 5 A 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, the base 1 being in... Figure 6 The middle part is roughly a shell-shaped opening facing the inner surface of the door 100. The other components of the door handle structure 200 are mounted on the base 1. The base 1 is mounted to the door 100. The base 1 can be fixed to the door 100 by fastener connection or welding, etc. The specific connection method is not limited here.

[0064] In addition, such as Figure 5 , 7As shown in Figure 10, the side of the base 1 facing the inner surface of the 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 generally formed with a second receiving cavity 1a and a first receiving cavity 1b. The first receiving cavity 1b is located below the second receiving cavity 1a. The base 1 is provided with a first gear 11, which is fixed on the base 1. The first gear 11 is located on the inner side of the base 1, specifically on the side wall portion 13 forming the first receiving cavity 1b. The flip cover 3 is provided with a second gear 31. The flip cover 3 includes a flip cover body 33, which 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.

[0065] like Figure 6 As shown, the lower center of the base 1 is the first receiving cavity 1b. Both sides of the top of the first receiving cavity 1b have partition walls 12, which serve as the bottom walls of the second receiving cavity 1a. The first partition wall 12 can have a through hole 12a, into which the mechanical lock cylinder 6 is inserted, and the keyhole 6a is exposed. The partition wall 12 is provided with a vertically penetrating slot 12b, which is a long slot extending along the inward and outward directions of the door 100. Figure 7 As shown, a connecting rod 32 is provided on the inner side of 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 integral structure, 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 set separately or as an integral unit. Let's look at... 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 on the inside. That is, the setting of the connecting rod 32 facilitates the inner and outer arrangement of the flip cover body 33 and the first gear 31. The setting of the connecting rod 32 should ensure that it does not interfere with the partition wall 12 during the flipping process. With this setting, both the first gear 11 and the second gear 31 are located on the inside of the base 1, which helps to protect the gear assembly and maintain a relatively neat appearance.

[0066] Let's look again. Figure 9 The door handle structure 200 in this embodiment also 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. The axis of the first rotating shaft 51 is the first axis X1. One end of the transmission rod 53 and the base 1 are rotatably connected through the first rotating shaft 51. Figure 5 As shown, the other end of the transmission rod 53 is rotatably connected to the second gear 31 via the second rotating shaft. The first axis X1 and the second axis X2 are parallel and extend roughly along the front-rear direction of the vehicle.

[0067] Let's look again. Figure 4 , 6 In this embodiment, the door handle structure 200 also includes a motor 2, which is also mounted on the base 1. As mentioned earlier, the base 1 has a second receiving cavity 1a, and the motor 2 is installed in the second receiving cavity 1a for better positioning and protection. The bottom center of the first receiving cavity 1a is an opening, corresponding to the top of the first receiving cavity 1b. The two sides of the bottom center of the first receiving cavity 1a are partition walls 12. When a control signal for opening or closing the door is received, the motor 2 can start working, that is, the motor 2 connects with terminal devices such as remote control keys or mobile phones.

[0068] Let's 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 generally cylindrical, and the rod 42 is connected to the radial side of the head 41. The head 41 is provided with a shaft hole 41a, and the rod 42 is provided with an opening 42a. The rod 42 is divided into two thin rods 422 and a crossbar 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 crossbar 421. In this way, the crossbar 421, the two thin rods 422 and one side of the head 41 enclose and form an elongated opening 42a.

[0069] Please continue to combine Figure 4 and refer to Figure 11 understand, Figure 11 for Figure 4 A schematic diagram showing the engagement position of the center lever 4 and the motor 2.

[0070] Motor 2 has an output shaft 21, which is inserted into the shaft hole 41a of the head 41 of lever 4. The side wall of the output shaft 21 can have a flat surface with a roughly D-shaped cross-section. The shaft hole 41a can also have a flat hole wall that mates with the flat surface. This anti-rotation fit between the output shaft 21 and the shaft hole 41a allows the head 41 of lever 4 to rotate when the output shaft 21 rotates. It can be seen that there are multiple ways to connect the output shaft 21 and lever 4. For example, they can be keyed together. Alternatively, the shaft hole 41a of lever 4 can be a non-circular hole such as a square or elliptical hole, and the shape of the output shaft 21 can be adapted to the shaft hole 41a to achieve the purpose of transmission connection. The lever 4 has an opening 42a on its rod portion 42. Figure 9 The transmission rod 53 of the middle transmission unit 5 is rotatably connected to the second gear 31 at one end, and an extension rod segment 531 that continues to extend upward is also connected thereto. The extension rod segment 531 and the transmission rod 53 can be an integral structure or a separate fixed connection. The top of the extension rod segment 531 is also provided with a hook portion 5311 extending towards the outside of the door 100. Figure 11The extension segment 531 of the transmission rod 53 extends out of the slot 12b and passes through the opening 42b of the lever 4. The hook portion 5311 of the extension segment 5311 passes outward through the opening 42b. In this way, when the output shaft 21 of the motor 2 rotates, it can drive the lever 4 to rotate. The crossbar portion 421 of the lever 4 can then move the extension segment 531 to drive the transmission rod 53 to rotate around the first axis X1.

[0071] It can be seen that the extension rod segment 531 and the lever 4 cooperate to achieve the actuation transmission. The hook portion 5311 is further provided because as the extension rod segment 531 and the lever 4 rotate, the opening 42a of the extension rod segment 531 and the lever 4 gradually disengages. The hook portion 5311 can ensure better contact and cooperation with the lever 4, which can be combined with... Figure 15 Understandably, after the flip cover 3 is fully opened, the extension rod segment 531 is no longer located in the opening 42a of the lever 4, while the hook portion 5311 is still inserted in the opening 42a.

[0072] Please continue to combine Figure 12-16 understand, Figure 12 This is a schematic diagram of the flip cover 3 of the door handle structure 200 in the embodiment of this application covering the handle operation port 100a of the car door 100; Figure 13 for Figure 12 Sectional view along line AA; Figure 14 This is a schematic diagram of the flip cover 3 of the door handle structure 200 in this embodiment of the application when it is fully open; Figure 15 for Figure 14 The sectional view from the center BB direction shows that, at this point, the flip cover 3 has been flipped to the second position. Figure 15 The dashed line in the middle indicates the dynamic trajectory of the flip cover 3's movement; Figure 16 for Figure 14 Sectional view along the CC direction.

[0073] like Figure 13 As shown, the output shaft 21 of motor 2 is in Figure 2 From a vantage point of view, rotating counterclockwise causes the lever 4 to rotate counterclockwise synchronously. The horizontal bar 421 of the lever 4 then pushes the extension segment 531 of the transmission rod 53 to rotate clockwise, specifically around the first axis X1. The transmission rod 53 rotates clockwise accordingly. The transmission rod 53 is also rotatably connected to the second gear 31 via a second rotating shaft. Therefore, as the transmission rod 53 rotates around the first axis X1, it drives the second gear 31 to rotate around the first axis X1. At this time, the second gear 31 is essentially revolving around the first axis. Since the second gear 31 is meshed with the first gear 11, it also rotates around the second axis X2 along the first gear 11. This means the second gear 31 is also essentially rotating on its own axis. It can be seen that the center of the circle corresponding to the first gear 11 and the first axis X1 should overlap. Thus, during its rotation, the second gear 31 drives the flip cover 3 to flip inward and upward. Figure 15 The diagram illustrates the movement trajectory of the flip cover 3 as it flips. The flip cover 3 moves from being sealed on the outside of the handle operation port 100a, gradually moving upward and inward, and finally stopping above the inside of the handle operation port 100a. At this time, the flip cover 3 is in the second position, and the handle operation port 100a is fully open.

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

[0075] Compared to the outward-opening, overhanging door handles in the prior art, in this embodiment, the mechanical handle 8 is no longer used to obstruct the handle operation opening 100a of the door 100. Instead, a flip cover 3, separately positioned from the mechanical handle 8, conceals the handle operation opening 100a. Furthermore, the flip cover 3 is configured to flip inwards and upwards, allowing operation of the mechanical handle 8 after the handle operation opening 100a is opened. The mechanical handle 8 does not need to be a cantilever structure, thus requiring lower strength and simplifying the manufacturing process. Moreover, similarly, compared to the inward-flipping door handles in the prior art, in this embodiment, the obstruction of the handle operation opening 100a and the unlocking mechanical handle 8 are separate. The flip cover 3 can flip upwards and inwards, ensuring that the door lock 400 position below the inner side of the handle operation opening 100a is not obstructed. This allows for the installation of a mechanical lock cylinder 6 on the side of the mechanical handle, meaning the door handle structure 200 can integrate a mechanical lock cylinder 6.

[0076] As can be seen from the above description, the door handle structure 200 in this embodiment of the application separates the flip cover 3 that blocks the handle operation port 100a and the mechanical handle 8. The flip cover 3 can block the handle operation port 100a. When it is necessary to open the door, the flip cover 3 flips inward and upward to open the handle operation port 100a and operate the mechanical handle 8. Therefore, it is only necessary to set an electric drive part of the motor type 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 described above, the door handle structure 200 is equipped with a transmission part 5 to drive the second gear 31 of the flip cover 3 to rotate around the first axis X1. Simultaneously, the second gear 31 of the flip cover 3 can also 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 these two motions. Figure 16As shown, if the mechanical lock cylinder 6 is too far from the door lock 400, a complex transmission mechanism is required, which may lead to physical unlocking failure. Therefore, in order to physically unlock the door lock 400, the mechanical lock cylinder 6 must be placed close to the door lock 400. Thus, when the flip cover 3 covers the handle operation port 100a, the mechanical lock cylinder 6 is located on the inside of the flip cover 3, near the unlocking actuator 7 and the door lock 400. In this way, when the flip cover 3 flips inward and upward, it will be close to the mechanical lock cylinder 6, which is prone to interference. As mentioned above, the placement of the mechanical lock cylinder 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 cylinder 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 a combination of two rotation forms: rotation around the second axis X2 and revolution around the first axis X1. Figure 16 As can be seen, the movement trajectory of the flip cover 3 is not an arc path from the outside to the inside, but gradually deviates from the arc path inward and upward. In this way, the distance between it and the mechanical lock cylinder 6 can be increased during the flipping and opening process, so as to avoid interference with the mechanical lock cylinder 6.

[0078] like Figure 16 As shown, the base 1 is provided with a partition wall 12 between the second accommodating cavity 1a and the first accommodating cavity 1b. The partition wall 12 can extend along the movement trajectory of the flip cover 3. In this way, the partition wall 12 can separate the flip cover 3 from the inner side of the base 1. In order to reduce friction, it can avoid contact with the flip cover 3.

[0079] Please continue to refer to this. Figure 9 In this embodiment, the transmission unit 5 specifically includes two transmission rods 53. Both transmission rods 53 are rotatably connected to the base 1 via a first rotating shaft 51. It can be understood that each of the two transmission rods 53 could also be connected to the base 1 via a corresponding rotating shaft. This embodiment uses a single first rotating shaft 51 to connect the two transmission rods 53, resulting in a simpler structure and easier assurance of coaxiality. The output shaft 21 of the motor 2 only cooperates with one lever 4; therefore, only one transmission rod 53 has an extension segment 531 to cooperate with the lever 4, while the other transmission rod 53 does not extend with an extension segment 531. Figure 7 As shown, the flip cover 3 has two second gears 31 arranged in the left-right direction (i.e., the front-rear direction of the vehicle). The two second gears 31 and the two transmission rods 53 are rotatably connected via a second shaft. Similarly, each of the two second gears 31 can be connected to the two transmission rods 53 via a shaft. Correspondingly, the base 1 also has two first gears 11, which mesh with the two second gears 31 one-to-one. With this arrangement, the transmission unit 5 provides more stable transmission to the flip cover 3. The flip cover 3 is driven to rotate by the two second gears 31, and the rotation is smooth and reliable.

[0080] Let's look again. Figure 4 , 5 As described above, in this embodiment, the base 1 is provided with a first receiving cavity 1b, which is located below the second receiving cavity 1a. The mechanical handle 8 can be located in the first receiving cavity 1b, and the two first gears 11 are respectively provided on the two side wall portions 13 of the first receiving cavity 1b. Therefore, the two transmission rods 53 mentioned above can be located on the side wall portions 13 on the left and right sides of the first receiving cavity 1b, specifically on the side of the side wall portion 13 away from the first receiving cavity 1b. Figure 5 In the design, supports 14 are provided on the left and right sides of the lower inner side of the base 1. The first rotating shaft 51 passes through the two supports 14. With this arrangement, the first gear 11 and the second gear 31 used for power transmission can be separated from the first accommodating cavity 1b and located inside the base 1. Thus, when the flip cover 3 is opened, the transmission part 5 and the first gear 11 are hidden inside the base 1, which serves to protect them and maintain a neat appearance. The left and right directions of the first accommodating cavity 1b and the base 1 mentioned here also correspond to the front and rear directions of the vehicle.

[0081] In this embodiment, both the first gear 11 and the second gear 31 have arc-shaped teeth and are not complete circular gear structures. This is mainly based on the flipping stroke of the flip cover 3. The arc-shaped teeth can save space and reduce transmission interference.

[0082] Furthermore, the mechanical handle 8 in this embodiment is specifically a push-button handle.

[0083] For details, please refer to Figure 17-19 understand, Figure 17 This is a schematic diagram of the flip cover 3 of the door handle structure 200 in the embodiment of this application covering the handle operation port 100a of the car door 100; Figure 18 for Figure 17 Sectional view along the DD direction; Figure 19 for Figure 17 EE-directed sectional view; Figure 20 This is a schematic diagram showing the engagement of the third gear 81 of the mechanical handle 8 and the fourth gear 71 of the unlocking actuator 7 in an embodiment of this application.

[0084] In this embodiment, the mechanical handle 8 includes a handle body 82, on which a third gear 81 is provided. The unlocking actuator 7 of the door 100 is provided with a fourth gear 71. The unlocking actuator 7 is connected to a cable 300 for unlocking the door lock 400. Figure 18 , 19As shown in Figure 20, the handle body 82 and the base 1 are rotatably connected via a 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 rotatably connected via a fourth rotating shaft 72, with the rotation axis being the fourth rotation axis X4. The third axis X3 of the third rotating shaft 83 and the fourth axis X4 of the fourth rotating shaft 72 are parallel. When the handle body 82 is pressed down, the handle body 82 rotates around the third axis X3 of the third rotating shaft 83, causing 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, which can drive the fourth gear 71 to rotate counterclockwise around the fourth rotation axis X4. Figure 20 In the middle, 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. When the operator presses the handle body 82 and pulls the door 100 outward, the door 100 can be opened.

[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 with reference to existing technology and will not be discussed further. The transmission method between the mechanical handle 8 and the unlocking actuator 7 is not limited to this; it is sufficient 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 part 15, which is located at the lower end of one side of the main structure of the base 1. Figure 4 , 5 As shown, the unlocking actuator 7 is installed on the mounting part 15. The unlocking actuator 7 is installed on the side of the mounting part 15 away from the inner surface of the door 100. Installing it in 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 or the control signal cannot be sent. Specifically, the flip cover 3 is manually pushed inward and upward to expose the keyhole 6a of the mechanical lock cylinder 6, and the mechanical lock cylinder 6 can be unlocked with a physical key to achieve an emergency unlocking function. Figure 4 , 13As shown, in this embodiment, the motor 2 drives the transmission part 5 to rotate around the first axis X1 via the lever 4. Specifically, the lever 4 is provided with an opening 42a, and the extension segment 531 of one end of the transmission rod 53 is inserted into the opening 42a. The extension segment 531 is moved by the crossbar part 421 of the lever 4. During the manual pushing of the flip cover 3, the lever 4 does not move, and the extension segment 531 of the transmission part 5 can rotate freely around the first axis X1 in the opening 42a and gradually move away from the crossbar part 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 is understood that the lever 4 is mainly designed to drive the flip cover 3 to rotate when it is driven to the second position. When the motor 2 fails to drive, the lever 4 or the motor 2 cannot rotate, but this will not interfere with the flip cover 3 rotating manually. Therefore, the lever 4 only needs to contact the extension rod segment 531 in the same pushing direction. It is not limited to the structure of the rod part 42 described above. For example, if the rod part 42 is a solid structure, it can directly contact the extension rod segment 531 for actuation. However, the method described above, which involves setting an opening 42a and relying on the crossbar part 421 for actuation, is more reliable and less prone to misalignment with the extension rod segment 531. Furthermore, without considering the failure of the motor 2, the rotation of the transmission rod 53 obviously does not need to be achieved through 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, such as Figure 9 As shown, a return spring 52 is also provided on the first rotating shaft 51 of the transmission unit 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 and generates a restoring force. When the flip cover 3 needs to return to the first position of the cover handle operating port 100a, the restoring force of the return spring 52 can drive the transmission rod 53 to rotate back. When the signal to close the door 100 is received, the motor 2 reverses to... Figure 15 From any perspective, lever 4 will rotate clockwise, and under the restoring force of return spring 52, extension segment 531 will rotate counterclockwise. Alternatively, if motor 2 fails and the flip cover 3 is manually flipped, the return spring 52 can also drive transmission rod 53 and extension segment 531 to rotate counterclockwise after manual operation is stopped, thereby causing the flip cover 3 to flip back to the first position. However, it is known that without lever 4, motor 2 can directly drive transmission rod 53 to rotate counterclockwise and clockwise, and return spring 52 is not required.

[0089] Finally, we can combine Figure 21 , 22 To understand the overall scheme of this embodiment, Figure 21This is a schematic diagram of the flip cover 3 flipping process in an embodiment of this application. From left to right, it shows the flip cover 3 opening process, and from right to left, it shows the flip cover 3 closing process. Figure 22 This is a schematic diagram of the unlocking process of the mechanical handle 8 in an embodiment of this application.

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

[0091] After the operator closes the door 100, motor 2 receives the closing control signal, and motor 2 reverses. Under the restoring force of the return spring 52, the flip cover 3 will move along... Figure 21 The movement proceeds sequentially from right to left, gradually flipping outwards and downwards until the handle operating port 100a is resealed.
