[0032] Embodiments of the present application are described in detail below with reference to the accompanying drawings, wherein the same or similar notations used throughout the drawings and the specific description denote the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0033] Unless otherwise specified, the front-rear direction in the present application is the longitudinal direction of the vehicle, i.e., the X direction; the left-right direction is the lateral direction of the vehicle, i.e., the Y direction; and the up-down direction is the vertical direction of the vehicle, i.e., the Z direction.

[0034] Reference is made below to Figures 1-5 The car door inner handle 100 according to an embodiment of the present application is described below, wherein the handle body 2 of the car door inner handle 100 can be automatically extended or retracted from the handle groove 102 of the car door 101, which is beneficial to realize unlocking or locking of the car door inner handle 100, effectively solve the risk of accidental opening of the car door 101 due to improper operation of the user, and better safety and reliability.

[0035] As Figures 1-5As shown, the vehicle door inner handle 100 according to the embodiment of the present application comprises a handle base 1, a handle body 2 and a driving assembly 3. The vehicle door inner handle 100 further comprises a housing 5, the housing 5 is fixedly connected with the vehicle door 101, the handle base 1 is fixedly installed on the housing 5 to be fixedly relative to the vehicle door 101, and the handle body 2 is movable relative to the housing 5.

[0036] The handle base 1 is adapted to be installed in the vehicle door 101, that is, the handle base 1 is fixedly installed between the inner panel and the outer panel of the vehicle door, so that the handle base 1 is invisible from both the inner side and the outer side of the vehicle door 101.

[0037] The handle body 2 is movably connected with the handle base 1, so that the handle body 2 is movable relative to the handle base 1, and the handle body 2 is provided with a handle portion 21 on the side away from the handle base 1. It should be noted that the handle body 2 can be installed on the side of the handle base 1 away from the outer panel of the vehicle door, and a handle slot 102 penetrating in the thickness direction is provided on the inner panel of the vehicle door, the handle body 2 can move away from the handle base 1 or move close to the handle base 1. The handle portion 21 can be configured as a handle for a user to hold, such as Figure 3 As shown, the handle portion 21 is formed with a holding opening 22, and the user's fingers can extend into the holding opening 22 to pull the handle portion 21.

[0038] Specifically, when the handle body 2 moves away from the handle base 1, the handle body 2 can move to a position opposite to the handle slot 102, and the handle portion 21 extends out of the handle slot 102, so that the vehicle door inner handle 100 is in an unlocked state, thereby facilitating the user to operate the handle portion 21 to open the vehicle door 101; and when the handle body 2 moves close to the handle base 1, the handle body 2 can move towards the handle slot 102, so that the handle portion 21 is retracted at the handle slot 102, such as being blocked at the handle slot 102, so that the vehicle door inner handle 100 is in a locked state, that is, the user cannot operate the vehicle door inner handle 100 from the inner side of the vehicle door 101, thereby avoiding the user from accidentally opening the vehicle door 101 due to improper operation.

[0039] The driving assembly 3 is used to drive the handle body 2 to move relative to the handle base 1, so that the handle portion 21 is selectively extended or retracted from the handle slot 102. In other words, the handle body 2 in the present application is neither directly manually operated by the vehicle occupant to unlock, nor unlocked by the unlocking button installed on the handle body 2, but automatically unlocked or locked by the driving assembly 3. The driving assembly 3 can be automatically controlled by the control system of the vehicle or controlled by other components which cannot be touched or unintentionally touched by the user.

[0040] And in actual design, the driving assembly 3 can be installed in the door 101, i.e. between the outer door panel and the inner door panel, so that the driving assembly 3 is not visible in the vehicle, thereby effectively avoiding the user from misoperating the driving assembly 3 and preventing the user from accidentally unlocking the inner door handle 100, greatly improving the use safety of the inner door handle 100.

[0041] According to the inner door handle 100 of the embodiment of the present application, the handle body 2 is automatically driven to move relative to the handle base 1, so that the handle portion 21 can be selectively extended or retracted from the handle groove 102, which can effectively prevent the user from unlocking the inner door handle 100 due to improper operation and improve the use safety of the inner door handle 100.

[0042] In some embodiments, the driving assembly 3 comprises a driver 31 and a driving arm 32, the driver 31 is fixedly installed on the housing 5 so that the driver 31 is fixed relative to the handle base 1, and the driving arm 32 is movably installed on the housing 5, such as being rotatably installed on the housing 5 through a pivot shaft 33, so that the driving arm 32 can rotate relative to the housing 5 and the handle base 1.

[0043] The driver 31 is connected to the driving arm 32, such as the output end of the driver 31 being provided with a push rod connected to the driving arm 32 through a pin shaft, so that the driver 31 can drive the driving arm 32 to move, thereby driving the driving arm 32 to rotate around the pivot shaft 33 when the driver 31 outputs driving force.

[0044] The driving arm 32 is connected to the handle body 2, such as one end of the driving arm 32 being rotatably connected to the handle body 2, so that the handle body 2 can be driven to move relative to the handle base 1 in the process of the driving arm 32 moving with the push rod, thereby driving the handle body 2 to move towards or away from the handle base 1, and thereby enabling the handle portion 21 to be selectively extended or retracted from the handle groove 102.

[0045] In addition, it should be noted that in the practical process of the inner door handle 100 of the present application, the driver 31 can be electrically connected to a control module such as a vehicle controller, so that the vehicle controller automatically controls the driver 31, thereby automatically realizing the operation of the driver 31, which is simple in structure and conducive to realizing the automatic unlocking and automatic locking of the inner door handle 100.

[0046] In some embodiments, the inner door handle 100 further comprises a guide 41 provided with a guide groove 42. The guide 41 can be configured as a plate-shaped member, and the guide groove 42 can be formed on the guide 41. Figure 3As shown, the driving arm 32 is located above the guide 41, and the guide groove 42 is formed on the upper surface of the guide 41, and the guide groove 42 is open upward, and the driving arm 32 is provided with a guide protrusion, such as a guide protrusion provided on the lower side of the driving arm 32, and the guide protrusion extends into the guide groove 42, and the guide protrusion slides along the guide groove 42, so that the driving arm 32 rotates relative to the handle base 1 under the guidance of the guide arm, and then the driving of the handle body 2 is realized.

[0047] Therefore, by setting the guide 41 to guide the movement process of the driving arm 32, and the guide 41 is located below the driving arm 32, which can also support the driving arm 32 to a certain extent, so as to ensure that the driving arm 32 moves along a specific trajectory, accurately pushes the handle body 2, and ensures that the car door inside handle 100 is accurately unlocked or locked.

[0048] In specific design, the guide protrusion can be set as a guide wheel, and the guide wheel is installed on the lower side of the driving arm 32, so that the guide wheel can extend into the guide groove 42 and roll along the guide groove 42, thereby reducing the movement resistance between the driving arm 32 and the guide 41, and reducing the power loss of the driver 31.

[0049] In some embodiments, the guide groove 42 is configured as an arc-shaped groove, and the center of the guide groove 42 coincides with the pivot shaft 33. It can be understood that the driving arm 32 rotates around the pivot shaft 33, that is, the extension direction of the guide groove 42 is the same as the extension direction of the movement trajectory of the driving arm 32. Therefore, during the movement of the driving arm 32, the driving arm 32 can be guided by the guide groove 42 to accurately drive the handle body 2.

[0050] In some embodiments, the driving assembly 3 is also provided with a damper 43 sleeved on the pivot shaft 33, and the damper 43 is used to apply a resistance to the driving arm 32 opposite to the driving force of the driver 31. The resistance of the damper 43 is smaller than the driving force of the driver 31, and the resistance gradually increases as the driving amplitude of the driver 31 to the driving arm 32 increases. Therefore, by setting the damper 43 to apply resistance to the driving arm 32, it is beneficial to reduce the movement acceleration of the driving arm 32, avoid the obvious impact feeling of the driving arm 32 when moving to the limit position, and reduce the movement noise.

[0051] The damper 43 can be configured as a damping spring, which is sleeved on the pivot shaft 33, so that the damper 43 can be stably installed on the pivot shaft 33, avoiding the damper 43 from being separated from the pivot shaft 33, and the structure is simple and convenient to install.

[0052] In some embodiments, the driving arm 32 is provided with a buffer, which is used to buffer when the driving arm 32 moves to the limit position, that is, the buffer can play a buffering role when the driving arm 32 moves.

[0053] The buffer is made of elastic material, such as a rubber pad, and two rubber pads are arranged on both sides of the driving arm 32 to buffer the driving arm 32 when the handle body 2 is opened or closed, so as to avoid the obvious impact when the driving arm 32 moves to the limit position and reduce the movement noise.

[0054] In some embodiments, the handle body 2 further includes two connecting rods, and each connecting rod is rotatably connected to the handle base 1 and the handle part 21 at both ends, so that the handle body 2 cooperates with the handle base 1 to form a four-bar linkage structure, and then the handle body 2 can move away from or close to the handle base 1 under the rotation of the connecting rod when the driving arm 32 drives the handle body 2, thereby achieving unlocking or locking of the in-door handle 100.

[0055] In particular design, the lengths of the two connecting rods can be set to be the same, and the two connecting rods are distributed in parallel and spaced apart between the handle body 2 and the handle base 1, so that the handle body 2 is always parallel to the handle base 1 during movement, thereby facilitating effective opening or closing of the handle slot 102 by the handle body 2.

[0056] In some embodiments, when the handle part 21 is in the retracted state, the difference between the inner side of the handle part 21 and the inner side of the door 101 is less than 1 mm, such as 0.1 mm or 0.5 mm. In other words, when the handle part 21 is retracted into the handle slot 102, the handle part 21 effectively closes the handle slot 102, and the difference between the inner side of the handle part 21 and the inner side of the door 101 is small, tending to an integral plane. Here, the inner side refers to the side facing the vehicle interior, and the outer side refers to the side away from the vehicle interior.

[0057] The inner side of the handle part 21 can be made of the same INS film process as the periphery of the handle slot 102, so that the handle part 21 can be integrated with the surrounding decorative parts when the handle slot 102 is closed, improving the delicate perception of the vehicle.

[0058] In some embodiments, the housing 5 includes an upper housing 51 and a lower housing 52, and the upper housing 51 and the lower housing 52 are detachably connected by a connecting piece, such as being fixed along the Z direction by 7 bolts. The handle base 1 is positioned and installed along the Y direction by the clamps of the handle base 1 and the upper housing 51 and the lower housing 52. The guide 41 is fixed to the upper housing 51 and the lower housing 52 by 3 bolts. The driver 31 is fixed to the upper housing 51 and the lower housing 52 by screws, and the interface of the driver 31 is arranged on the lower side to prevent rainwater from entering and ensure the stable function of the driver 31.

[0059] The application further provides a control system of the vehicle door inner handle 100.

[0060] The control system of the vehicle door inner handle 100 according to the embodiment of the application comprises a control module and the vehicle door inner handle 100 of any one of the above embodiments. The control module is electrically connected with the driver 31 of the vehicle door inner handle 100, so that the control module can control the state of the driver 31. Specifically, the control module is configured to control the handle body 2 to move away from the handle base 1 when receiving an opening signal, and control the handle body 2 to move towards the handle base 1 when receiving a closing signal.

[0061] The control module can be a vehicle controller, and the opening signal is a signal sent after the vehicle is put into the “P” gear or the “unlock” key is pressed. After the vehicle is put into the “P” gear or the “unlock” key is pressed, the control module receives the opening signal and outputs a control signal to the driver 31. After receiving the control signal, the driver 31 drives the driving arm 32, the driving arm 32 is driven by the pulling force of the driver 31 to slide on the guide 41, and at the same time, the handle body 2 is separated from the handle base 1, until the handle body 2 moves to a set position, the handle part 21 extends out of the handle groove 102, and the vehicle door inner handle 100 is opened, thereby realizing the unlocking process of the vehicle door inner handle 100. At this time, the user can operate the handle part 21 to open the vehicle door 101.

[0062] In addition, the closing signal is a signal sent after the vehicle starts. That is, after the vehicle starts, the control module receives the closing signal and outputs a control signal to the driver 31. After receiving the control signal, the driver 31 drives the driving arm 32, the driving arm 32 is driven by the pulling force of the driver 31 to slide on the guide 41, and at the same time, the handle body 2 is separated from the handle base 1, until the handle body 2 moves to a set position, the handle part 21 extends out of the handle groove 102, and the vehicle door inner handle 100 is opened, thereby realizing the unlocking process of the vehicle door inner handle 100. At this time, the user cannot operate the handle part 21 to open the vehicle door 101.

[0063] Therefore, the automatic unlocking or locking of the vehicle door inner handle 100 can be realized, the degree of automation is high, and the situation that the vehicle door inner handle 100 cannot be unlocked due to improper operation of the user can be effectively avoided, thereby improving the safety of the vehicle door inner handle 100.

[0064] The application further provides a vehicle.

[0065] According to the vehicle of the embodiment of the present application, the control system of the door inner handle 100 of any one of the above embodiments is provided, and the handle body 2 can be automatically driven to move relative to the handle base 1 according to the state of the vehicle, so that the handle part 21 can be selectively extended from or retracted from the handle groove 102, which can effectively avoid that the user unlocks the door inner handle 100 due to improper operation, and improve the use safety of the door inner handle 100.

[0066] Therefore, the user can avoid unlocking the door inner handle 100 by mistake during the driving of the vehicle, and even open the door 101 during the driving of the vehicle, which improves the safety of the user during the driving of the vehicle and improves the experience of the user during the driving of the vehicle.
