Description

Technical Field

[0001] The present application relates to the field of vehicle door handles, and in particular to a hidden vehicle door handle structure. Background Art

[0002] With the continuous iterative development of the automobile industry, the competition in the vehicle market has become more intense, and the requirements for automobile styling and design have become higher and higher, and hidden handles have come into being. Hidden handles are hidden inside the car door during the vehicle's movement, which improves the integrity of the vehicle's overall appearance, reduces wind resistance during driving, and makes the vehicle have better wind noise performance and fuel economy.

[0003] At present, most common hidden handles for cars are driven by motors. The working principle is that when the door handle is needed, the motor uses a transmission structure such as a gear or worm assembly to extend the handle from the door or lift one end of the handle, and then manually pull the handle to open the door. However, the structure of extending the handle through the coordination of gears and worm assemblies is complex and the manufacturing cost is relatively high. Utility Model Content

[0004] In order to solve the problem that common hidden door handles have complex structures and high costs, the present application provides a hidden door handle structure, which has the advantages of simple structure, convenient implementation and low cost.

[0005] The present application provides a hidden door handle structure that adopts the following technical solution:

[0006] A hidden door handle structure, comprising:

[0007] A base is embedded in the vehicle door and close to the outer side of the vehicle door, wherein an installation space is provided inside the base, and an opening communicating with the internal installation space is formed on the outer side of the vehicle door;

[0008] A handle is embedded in the opening and has a hidden position, a working position and a trigger position;

[0009] A swing assembly, the swing assembly comprising a first swing member and a second swing member, two ends of the first swing member are rotatably mounted on the handle and in the mounting space respectively, two ends of the second swing member are rotatably mounted on the handle and in the mounting space respectively, the handle is linked with the first swing member and the second swing member;

[0010] A driving assembly, used to drive the swing assembly to move, so as to switch the handle from a hidden position to a working position;

[0011] An unlocking assembly, linked to the handle, for unlocking the door when the handle is pulled to a trigger position;

[0012] The driving assembly comprises a lifting member and a driving member driving the lifting member to rotate, and the lifting member drives the swinging assembly to move by rotating.

[0013] By adopting the above technical solution, the first swinging member and the second swinging member form a linkage structure with the handle, and the handle can be extended from the outside of the door for human hand to grasp by driving the swinging member to move by the driving member. The linkage structure is simple and reliable and not prone to failure. At the same time, the second swinging member cooperates with the first swinging member to form a dynamic support for the handle, and the handle can achieve stable movement and remain basically parallel to the base and extend outward, making it easy for human hand to grasp the handle. The rotation driving method of the lifting member is simple and reliable, without the need for complex structures such as worm gears, and is easy to implement, low cost, and has good economy.

[0014] Optionally, the lifting member includes an axial portion and an abutment portion, the axial portion is cylindrical, and the abutment portion is formed on a curved surface of the axial portion and extends in a direction gradually away from the axis of the axial portion along the circumference of the axial portion.

[0015] By adopting the above technical solution, by making the outer side surface of the abutment part gradually move away from the axis of the shaft center part, the lifting part as a whole is shaped like a "comma" or "magatama". When the driving part is used to drive the lifting part to rotate around the axis of the shaft center part, the distance between the swinging part and the axis of the shaft center part can be gradually increased or decreased, thereby realizing the driving of the swinging assembly. The structure is simple and easy to implement, can effectively reduce the failure rate, and has good durability.

[0016] Optionally, when the handle is in the hidden position, the axial portion abuts against the first swinging member, and when the handle is in the working position, the abutting portion abuts against the first swinging member.

[0017] By adopting the above technical solution, the lifting member only needs to act on one of the swinging members to drive the entire swinging assembly and the handle, which further simplifies the matching relationship between the driving assembly and the swinging assembly.

[0018] Optionally, when the handle is in the working position, the first swinging member is clamped and fixed by the lifting member and the base, the handle is provided with a sliding groove, and the connecting shaft between the second swinging member and the handle is slidably arranged in the sliding groove.

[0019] By adopting the above technical solution, the connecting axis between the second swinging member and the handle and the sliding groove are used to slide together, so that a person can pull the handle by hand to flip it around the connecting axis between the first swinging member and the handle, thereby triggering the unlocking component and opening the car door.

[0020] Optionally, both the first swinging member and the second swinging member are U-shaped structures.

[0021] By adopting the above technical solution, the first swing member and the second swing member of the U-shaped structure can avoid the structure inside the handle and the base, improve space utilization, and reduce the volume of the entire door handle. At the same time, the two ends of the first swing member and the two ends of the second swing member can maintain a certain linear distance, thereby providing a sufficient range of movement for the handle to meet the needs of use.

[0022] Optionally, the handle includes a gripping portion, a first mounting portion and a second mounting portion, the first mounting portion and the second mounting portion are formed on a side wall of the gripping portion away from the outer side of the vehicle door, the connecting axis between the first swinging member and the handle is arranged in the first mounting portion, and the connecting axis between the second swinging member and the handle is arranged in the second mounting portion.

[0023] By adopting the above technical solution, by arranging the connecting shafts of the first swinging member and the second swinging member and the handle in the first mounting part and the second mounting part respectively, after the handle is extended from the base, the connecting shaft will not be directly exposed, thereby avoiding contamination by impurities that affect the rotation effect of the connecting shaft, and at the same time improving the integrity and aesthetics of the handle.

[0024] Optionally, the installation space is provided with a plurality of buffer members, and the buffer members are used to alleviate the impact between the swing assembly and the handle and the inner wall of the installation space.

[0025] By adopting the above technical solution, when the handle switches position, the buffer can prevent the swing assembly or the handle from directly colliding with the inner wall of the base, avoiding damage to the internal part of the handle structure when the door is opened forcefully, thereby improving the durability and stability of the overall structure.

[0026] Optionally, a reset member is provided on the swing assembly for resetting the handle to a hidden position after the door is closed.

[0027] By adopting the above technical solution, by setting a reset member, the handle can automatically switch from the trigger position to the working position or from the working position to the hidden position when not in use, without the need for other driving structures. The structure is simple and easy to implement, which can effectively save costs.

[0028] In summary, the present application includes at least one of the following beneficial technical effects:

[0029] 1. The first swing member and the second swing member form a linkage structure with the handle. The swing member is driven by the driving assembly to move so that the handle can be extended from the outside of the door for grabbing by hand. The linkage structure is simple and reliable and not prone to failure. At the same time, the second swing member cooperates with the first swing member to form a dynamic support for the handle. The handle can move stably and extend outward substantially parallel to the base, making it easy for a person to grab the handle. The rotation drive method of the lifting member is simple and reliable, without the need for complex structures such as worm gears, and is easy to implement, low in cost, and has good economic efficiency.

[0030] 2. By gradually moving the outer side surface of the abutment portion away from the axis of the shaft center, the lifting member is shaped like a "comma" or "magatama" as a whole. When the lifting member is driven by the driving member to rotate around the axis of the shaft center, the distance between the swing member and the axis of the shaft center can be gradually increased or decreased, thereby realizing the driving of the swing assembly. The structure is simple and easy to implement, which can effectively reduce the failure rate and has good durability.

[0031] 3. The use of a buffer can prevent the swing assembly or the handle from directly colliding with the inner wall of the base when the handle switches positions, thereby avoiding damage to the internal structure of the handle when the door is opened forcefully, thereby improving the durability and stability of the overall structure.

DETAILED DESCRIPTION

[0039] The following is combined with Figure 1-4 This application is described in further detail.

[0040] The present application discloses a hidden door handle structure. Figure 1 and Figure 2, comprising a base 1 and a handle 2. The base 1 is embedded in the door and close to the outside of the door. An installation space 11 is provided inside the base 1, and an opening connected to the internal installation space 11 is formed on the outside of the door. The handle 2 is embedded in the opening. A swing assembly 3, a drive assembly 4 and an unlocking assembly are arranged in the installation space 11. The handle 2 is linked with the swing assembly 3 and has a hidden position, a working position and a trigger position. The drive assembly 4 is used to drive the swing assembly 3 to move so as to drive the handle 2 to move. The unlocking assembly is used to cooperate with the handle 2 to unlock the door.

[0041] Reference Figure 1 a, the handle 2 is in a hidden position under normal conditions, at which time the handle 2 is retracted into the installation space 11 of the base 1, and the side of the handle 2 close to the outside of the vehicle is flush with the outer side of the vehicle door; Figure 1 b. When the door needs to be opened, the driving assembly 4 drives the swing assembly 3 to move and extends the handle 2 from the opening for a person to grab. At this time, the handle 2 is in the working position; Figure 1 c. Then, a person manually pulls the handle 2 to rotate and trigger the unlocking assembly to unlock the door. At this time, the handle 2 is in the triggering position.

[0042] Specifically, refer to Figure 2 , Figure 3 and Figure 4 The handle 2 includes a gripping portion 21, a first mounting portion 22 and a second mounting portion 23. The first mounting portion 22 and the second mounting portion 23 are formed on the side wall of the gripping portion 21 away from the outer side of the vehicle door. The gripping portion 21 is used for being grasped by a hand to open the vehicle door. The first mounting portion 22 and the second mounting portion 23 are both used to connect the first swinging member 31 and the second swinging member 32 to cooperate in realizing the state switching of the handle 2.

[0043] Further, refer to Figure 2 , Figure 3 and Figure 4 The swing assembly 3 includes a first swing member 31 and a second swing member 32. One end of each of the first swing member 31 and the second swing member 32 is rotatably mounted in the mounting space 11 of the base 1. The other end of the first swing member 31 is rotatably mounted inside the first mounting portion 22. The other end of the second swing member 32 is rotatably mounted inside the second mounting portion 23. The handle 2, the first swing member 31, and the second swing member 32 form a linkage structure. When the first swing member 31 and the second swing member 32 swing synchronously, the handle 2 extends with the outer wall approximately parallel to the outer side of the door, so that the handle 2 is switched from the hidden position to the working position for human hand grasping.

[0044] Meanwhile, the driving assembly 4 is arranged in the installation space 11 and is located on one side of the first swinging member 31 . The driving assembly 4 drives the first swinging member 31 to swing, thereby causing the swinging assembly 3 and the handle 2 to move synchronously and switch the position of the handle 2 .

[0045] Specifically, refer to Figure 2 , Figure 3 and Figure 4 The driving assembly 4 includes a lifting member 41 and a driving member 42 for driving the lifting member 41 to rotate. The lifting member 41 drives the first swing member 31 to rotate by rotating, thereby realizing the position switching of the handle 2. The lifting member 41 includes an axial portion 411 and an abutting portion 412. The axial portion 411 is cylindrical. The output shaft of the driving member 42 is coaxially connected to the axial portion 411. The abutting portion 412 is formed on the curved surface of the axial portion 411 and extends along the circumference of the axial portion 411 in a direction gradually away from the axis of the axial portion 411. The axis of the axial portion 411 is parallel to the axis of the rotating shaft of the first swing member 31.

[0046] When the handle 2 is in the hidden position, the first swing member 31 abuts against the curved surface of the shaft portion 411. When the driving member 42 drives the lifting member 41 to rotate around the axis of the shaft portion 411, the abutting portion 412 gradually contacts the first swing member 31, and as the shaft portion 411 gradually rotates, the distance between the contact point of the first swing member 31 and the abutting portion 412 and the axis of the shaft portion 411 gradually increases, so that the first swing member 31 rotates in a direction away from the shaft portion 411, and cooperates with the second swing member 32 to extend the handle 2 from the base 1 and switch to the working position.

[0047] In addition, when the handle 2 is switched to the working position, the side of the first swing member 31 away from the lifting member 41 abuts against the inner wall of the base 1. At this time, the first swing member 31 is clamped and fixed by the lifting member 41 and the inner wall of the base 1 to ensure the stability of the handle 2 when it is in the working position.

[0048] Further, refer to Figure 2 , Figure 3 and Figure 4 The second mounting portion 23 is located on both sides of the second swinging member 32 and has sliding grooves 231 , and the ends of the connecting shaft between the second swinging member 32 and the second mounting portion 23 are respectively extended into the two sliding grooves 231 and slidably matched with the sliding grooves 231 .

[0049] When the handle 2 is in the working position, the first swinging member 31 remains fixed. At this time, a person grabs the gripping portion 21 and pulls the handle 2 outward, and the handle 2 as a whole rotates around the connecting shaft between the first swinging member 31 and the first mounting portion 22, and the second swinging member 32 rotates synchronously, and the connecting shaft between the second swinging member 32 and the second mounting portion 23 slides correspondingly in the sliding groove 231, so that the handle 2 moves in a flipped posture. Until the second swinging member 32 abuts against the inner wall of the base 1, the handle 2 enters the trigger position, triggering the unlocking assembly to open the door.

[0050] In this embodiment, the unlocking assembly is linked with the second swinging member 32. When the handle 2 is switched from the working position to the triggering position, the second swinging member 32 will drive the unlocking assembly and trigger the unlocking structure of the door to open the door.

[0051] Further, refer to Figure 2 A reset member 5 is provided at the connection shaft between the first swing member 31 and the base 1 and at the connection shaft between the second swing member 32 and the base 1. The reset member 5 generates a circumferential force at the connection shaft, so that the first swing member 31 or the second swing member 32 has a tendency to rotate toward the bottom of the base 1 to reset the handle 2. In this embodiment, the reset member 5 is configured as a torsion spring.

[0052] When the door is opened, the handle 2 is in the trigger position. After the door is opened, the person releases the handle 2, and the second swing member 32 retracts inwards under the action of the reset member 5, driving the handle 2 to enter the working position, and the connecting shaft between the second swing member 32 and the second mounting portion 23 slides correspondingly in the sliding groove 231. When the door is closed, the driving member 42 drives the lifting member 41 to gradually rotate and reset, and the first swing member 31 rotates in the direction close to the base 1 under the action of the reset member 5, and the second swing member 32 rotates synchronously under the action of the reset member 5, thereby retracting the handle 2 in the base 1 and entering the hidden position.

[0053] Furthermore, the first swing member 31 and the second swing member 32 are both U-shaped structures, which are convenient for avoiding other structures to cooperate with the handle 2 to extend from the base 1. When the handle 2 is in the working position or the trigger position, the end of the first swing member 31 connected to the handle 2 and the end of the second swing member 32 connected to the handle 2 extend from the base 1. It should be noted that at this time, the first swing member 31 and the second swing member 32 are not directly exposed to the outside, the end of the first swing member 31 is located in the first mounting portion 22, and the end of the second swing member 32 is located in the second mounting portion 23, thereby protecting the connecting shaft of the first swing member 31 and the connecting shaft of the second swing member 32 to avoid contact with external impurities and affecting the normal rotation of the connecting shaft.

[0054] Further, refer to Figure 2 , Figure 3 and Figure 4 A plurality of buffer members 6 are arranged in the installation space 11 of the base 1. The buffer members 6 are arranged on the inner wall of the installation space 11 and are used to alleviate the impact between the swing assembly 3 and the handle 2 and the inner wall of the installation space 11 to achieve a shock absorbing effect.

[0055] In this embodiment, three buffer members 6 are provided, two of which are located on the side wall of the installation space 11 away from the outside of the vehicle door, and when the handle 2 is in the hidden position, the handle 2 and the first swing member 31 respectively abut against the two buffer members 6; another buffer member 6 is located on the side wall of the installation space 11 close to the outside of the vehicle door, and when the handle 2 is in the working position or the trigger position, the first swing member 31 abuts against the buffer member 6, and the other side of the first swing member 31 is tightly abutted by the lifting member 41. In other embodiments, other numbers and distribution positions can also be set as long as the shock absorbing effect can be achieved.

[0056] The implementation principle of a hidden door handle structure disclosed in the embodiment of the present application is:

[0057] In normal state, the handle 2 is in a hidden position, and the handle 2 and the swing assembly 3 are both retracted into the installation space 11 of the base 1;

[0058] When the door needs to be opened, the lifting member 41 is driven to rotate, and the first swing member 31 is rotated in a direction away from the lifting member 41, and the swing assembly 3 and the handle 2 are extended from the base 1 until the first swing member 31 is pressed against the inner wall of the base 1, and the handle 2 enters the working position;

[0059] A person grasps the gripping portion 21 and pulls the handle 2 outwards, and the handle 2 rotates around the connecting axis between the first swinging member 31 and the base 1 , and at the same time drives the second swinging member 32 to rotate, so as to drive the unlocking component and unlock and open the door.

[0060] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
