[0033] Embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where like or similar reference numerals denote like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present application, and should not be construed as limiting the present application.

[0034] The inner door handle assembly of the embodiment of the present application will be described below with reference to the accompanying drawings.

[0035] The inner door handle assembly provided by the embodiment of the present application can be applied to the doors of heavy-duty tractors, facilitating two-way unlocking (pulling the handle body to the left or pulling the handle body to the right) of the door by relevant personnel. It should be noted that the lightweight-designed inner door handle assembly can be extended and applied to similar demand structures such as passenger cars, RVs, and new energy vehicles.

[0036] As Figure 1 、 Figure 2 and Figure 8 shown, the inner door handle assembly of the embodiment of the present application may include: a mounting seat 1, an in-vehicle handle member 2, a first unlocking assembly 3, and a second unlocking assembly 4.

[0037] Among them, the in-vehicle handle member 2 is axially rotatably arranged on the mounting seat 1, and the first unlocking assembly 3 and the second unlocking assembly 4 are axially rotatably arranged on the mounting seat 1.

[0038] The in-vehicle handle member 2 can drive the first unlocking assembly 3 to rotate clockwise and can drive the second unlocking assembly 4 to rotate counterclockwise; the rotations of the first unlocking assembly 3 and the second unlocking assembly 4 do not affect or limit each other.

[0039] It can be understood that when the in-vehicle handle member 2 described in this embodiment rotates axially (clockwise and counterclockwise), it can drive the first unlocking assembly 3 and the second unlocking assembly 4 to rotate respectively and unlock the target door.

[0040] It should be noted that when the in-vehicle handle member 2 described in this embodiment drives the first unlocking assembly 3 to rotate clockwise, it does not drive the second unlocking assembly 4 to rotate, and when the in-vehicle handle member 2 drives the second unlocking assembly 4 to rotate counterclockwise, it does not drive the first unlocking assembly 3 to rotate.

[0041] In an embodiment of the present application, as Figure 3 shown, the in-vehicle handle member 2 includes: a handle body 21, a first control arm 22 extending from the handle body 21 toward the side close to the first unlocking assembly 3, and a second control arm 23 extending from the handle body 21 toward the side close to the second unlocking assembly 4.

[0042] It can be understood that the handle body 21 described in this embodiment can rotate on the mounting seat 1.

[0043] The first control arm 22 controls the rotation of the first unlocking component 3, and the second control arm 23 controls the rotation of the second unlocking component 4.

[0044] It should be noted that in this embodiment, the handle body 21 can toggle the first unlocking component 3 through the first control arm 22 to unlock the unlocking mechanism of the target vehicle door through the first unlocking component 3, and the handle body 21 can toggle the second unlocking component 4 through the second control arm 23 to unlock the unlocking mechanism of the target vehicle door through the second unlocking component 4.

[0045] To clearly illustrate the previous embodiment, in an embodiment of the present application, as Figure 1 and Figure 4 , the first unlocking component 3 may include: a long rocker arm 31, a first cylindrical connecting member 32, a first torsion spring 33, and a first flap 34.

[0046] Among them, the long rocker arm 31 is rotatably connected to the mounting seat 1 through the first cylindrical connecting member 32, the first torsion spring 33 is sleeved on the first cylindrical connecting member 32, the first flap 34 is disposed on the long rocker arm 31, and the first control arm 22 is in contact connection with the first flap 34.

[0047] The first flap 34 is a bent plate, and the first flap 34 may include: a first sheet body 341.

[0048] Among them, the upper end of the first sheet body 341 is bent downward to form a first bent portion 342, and the upper end of the first bent portion 342 is bent downward to form a second bent portion 343. Among them, the first control arm 22 is in contact connection with the first sheet body 341, the first bent portion 342, and the second bent portion 343 respectively according to different rotation angles of the handle body 21.

[0049] It should be noted that in the normal (non-unlocking the vehicle door) state of the first control arm 22 described in this embodiment, the first control arm 22 is in contact connection with the first sheet body 341. During the clockwise rotation of the first control arm 22, as the rotation angle gradually increases, the first control arm 22 (for example, the contact surface and contact corner of the first control arm 22) will be in contact connection with the first sheet body 341, the first bent portion 342, and the second bent portion 343 in sequence. When the first control arm 22 abuts against different positions of the first flap 34, the rotation angle of the first flap 34 is different.

[0050] Specifically, as Figure 9When a relevant person (e.g., a driver) needs to open the target vehicle door, the relevant person can turn the handle body 21 to the left. The handle body 21 can drive the first control arm 22 to toggle the first paddle 34. According to the rotation angle of the handle body 21, the first control arm 22 successively contacts the first blade 341, the first bending part 342, and the second bending part 343. After the first control arm 22 abuts against the second bending part 343, the unlocking of the unlocking mechanism of the target vehicle door is completed. By bending the first paddle 34, the relevant person can open the target vehicle door without turning the handle body 21 to the left significantly.

[0051] Furthermore, one force-bearing end of the first torsion spring 33 is connected to the mounting seat 1, and the other force-bearing end of the first torsion spring 33 abuts against the surface of the first paddle 34 away from the first control arm 22. The first torsion spring 33 is used to reset the handle body 21 through the long rocker arm 31 after the long rocker arm 31 unlocks the vehicle door.

[0052] It can be understood that when the handle body 21 described in this embodiment controls the long rocker arm 31 to rotate clockwise, the first paddle 34 can press the other force-bearing end of the first torsion spring 33. After the relevant person opens the target vehicle door by turning the handle body 21, the handle body 21 can be released, and the handle body 21 is reset by the resilience of the first torsion spring 33.

[0053] In an embodiment of the present application, as Figure 1 and Figure 5 , the second unlocking component 4 may include: a short rocker arm 41, a second cylindrical connecting piece 42, a second torsion spring 43, and a second paddle 44.

[0054] Among them, the short rocker arm 41 is rotatably connected to the mounting seat 1 through the second cylindrical connecting piece 42, and the second torsion spring 43 is sleeved on the second cylindrical connecting piece 42. The second paddle 44 is a bent plate, and the second paddle 44 is arranged on the short rocker arm 41. The second control arm 23 is in contact connection with the second paddle 44.

[0055] The second paddle 44 is a bent plate, and the second paddle 44 may include: a second blade 441.

[0056] Among them, the lower end of the blade is bent upward to form a third bending part 442, and the lower end of the first bending part 342 is bent upward to form a fourth bending part 443. The second control arm 23 is in contact connection with the second blade 441, the third bending part 442, and the fourth bending part 443 respectively according to the different rotation angles of the handle body 21.

[0057] It should be noted that, when the second control arm 23 described in this embodiment is in the normal state (door not unlocked), the second control arm 23 is connected with the second sheet 441 in abutment with it. When the second control arm 23 rotates clockwise, as the rotation angle gradually increases, the second control arm 23 (for example, the abutting surface and abutting corner of the second control arm 23) will successively be connected with the second sheet 441, the third bending portion 442, and the fourth bending portion 443 in abutment with it. When the second control arm 23 abuts against different positions of the second sheet 441, the rotation angle of the second sheet 441 is different.

[0058] Specifically, if Figure 10 As shown, when the relevant personnel (for example, the driver) needs to open the target door, the relevant personnel can bend the handle body 21 to the right, and the handle body 21 can be used to push the second paddle 44 through the second control arm 23. The second control arm 23 contacts the second sheet 441, the third bending portion 442, and the fourth bending portion 443 in sequence according to the rotation angle of the handle body 21. When the first control arm 22 contacts the fourth bending portion 443, the unlocking mechanism of the target door is unlocked. By bending the second paddle 44, the relevant personnel can open the target door without having to bend the handle body 21 to the right significantly.

[0059] Furthermore, one force-bearing end of the second torsion spring 43 is connected to the mounting seat 1, and the other force-bearing end of the second torsion spring 43 is connected to the surface of the second paddle 44 away from the second control arm 23, wherein the second torsion spring 43 is used to reset the handle body 21 through the short rocker arm 41 after the short rocker arm 41 unlocks the vehicle door.

[0060] It can be understood that when the handle body 21 described in this embodiment controls the short rocker arm 41 to rotate clockwise, the second paddle 44 can press the other force-bearing end of the second torsion spring 43. When the relevant personnel open the target door by prying the handle body 21, the handle body 21 can be released, and the handle body 21 can be reset through the rebound force of the second torsion spring 43.

[0061] In one embodiment of the present application, Figure 1 , Figure 5 and Figure 6 As shown, connecting holes 5 are respectively formed on the ends of the long rocker arm 31 and the short rocker arm 41 .

[0062] The connecting hole 5 is used to connect to the end of the unlocking rope of the unlocking mechanism so as to open the unlocking mechanism through the unlocking rope.

[0063] Specifically, the two unlocking ropes of the unlocking mechanism of the target vehicle door are respectively connected to the connecting holes 5 of the long rocker arm 31 and the short rocker arm 41. When the long rocker arm 31 and the short rocker arm 41 rotate, the unlocking ropes of the unlocking mechanism of the target vehicle door can be pulled to control the unlocking mechanism of the target vehicle door to unlock the vehicle door.

[0064] It should be noted that the pulling force of one rocker arm by the pulling rope is relatively small, while the pulling force of the other rocker arm by the pulling rope is relatively large. In order to keep the forces on the left and right approximately the same, the sizes of the two rocker arms are different, which is convenient for relevant personnel to use.

[0065] Furthermore, the long rocker arm 31 and the short rocker arm 41 are arranged vertically, which saves more space in the mounting seat 1 compared to arranging the rocker arms side by side.

[0066] In an embodiment of the present application, as Figure 1 , the mounting seat 1, the in-vehicle handle member 2, the first unlocking assembly 3 except the first torsion spring 33, and the second unlocking assembly 4 except the second torsion spring 43 are all made of plastic material by an injection molding process.

[0067] Among them, the in-vehicle handle member 2 is made of PC + ABS material, and the mounting seat 1, the first unlocking assembly 3 except the first torsion spring 33, and the second unlocking assembly 4 except the second torsion spring 43 are all made of PA6 + GF50 material.

[0068] The following material process table:

[0069] Name Material Process Inner Car Handle PC+ABS Injection Molding Mounting Seat PA6+GF50 Injection Molding First Unlocking Component Except the First Torsion Spring PA6+GF50 Injection Molding Second Unlocking Component Except the Second Torsion Spring PA6+GF50 Injection Molding

[0070] It should be noted that the rotating shaft 7 can be made of 45Cr15 material, while the first torsion spring 33 and the second torsion spring 43 can be made of 65Mn material.

[0071] It can be understood that except for the rotating shaft 7, the first torsion spring 33, and the second torsion spring 43, the in-vehicle door handle assembly of the present application is made of plastic material and is formed by an injection molding process. Most of it is made of plastic material, meeting the lightweight design and making the present application applicable to different types of vehicle doors.

[0072] In an embodiment of the present application, as Figure 1 、 Figure 6 、 Figure 7 shown, the handle body 21, the first control arm 22, and the second control arm 23 are connected to the mounting seat 1 through the rotating shaft 7. Among them, the rotation angle of the handle body 21 on the mounting seat 1 is not greater than 20°.

[0073] It should be noted that due to the bending treatment of the first flap 34 and the second flap 44, the handle body 21 only needs to drive the first control arm 22 and the second control arm 23 to rotate a small angle (not greater than 20°) to open the car door, which is more convenient and labor-saving to use.

[0074] A plurality of weight reduction grooves and weight reduction holes are respectively formed on the mounting seat 1, the in-vehicle handle member 2, the long rocker arm 31 and the short rocker arm 41. Among them, reinforcing ribs are provided on the mounting seat 1, the in-vehicle handle member 2, the long rocker arm 31 and the short rocker arm 41.

[0075] It should be noted that the mounting seat 1, the in-vehicle handle member 2, the long rocker arm 31 and the short rocker arm 41 described in this embodiment are provided with a plurality of weight reduction grooves and weight reduction holes on the basis of ensuring their own strength, which greatly reduces the weight of the in-vehicle door handle assembly.

[0076] In an embodiment of the present application, it may further include: an in-vehicle door handle decorative panel 6. Among them, the in-vehicle door handle decorative panel 6 is connected to the mounting seat 1 through a plurality of buckles, and the in-vehicle door handle decorative panel 6 is used to block the internal structure.

[0077] It can be understood that the in-vehicle door handle decorative panel 6 described in this embodiment is formed by an injection molding process (using PC + ABS), installed on the mounting seat 1, used to block the internal structure, prevent seeing through the internal structure, dust-proof and sealed, and beautify the appearance.

[0078] As Figure 11 shown, an installation method of an in-vehicle door handle assembly may include:

[0079] Step 101, the in-vehicle handle member is installed on the mounting seat through a pin;

[0080] Step 102, the long rocker arm is installed on the mounting seat through a first cylindrical connector sleeved with a first torsion spring;

[0081] Step 103, adjust the first torsion spring so that both ends of the first torsion spring are respectively connected to the first flap and the mounting seat;

[0082] It should be noted that two convex columns extend from the mounting seat described in this embodiment, and there is a gap between the two convex columns, and one force-bearing end of the first torsion spring can be clamped in this gap.

[0083] Step 104, the short rocker arm is installed on the mounting seat through a second cylindrical connector sleeved with a second torsion spring;

[0084] Step 105, adjust the second torsion spring so that both ends of the second torsion spring are respectively connected to the second flap and the mounting seat;

[0085] It should be noted that in this embodiment, two convex columns extend from the mounting base, and there is a gap between the two convex columns. One force-bearing end of the second torsion spring can be clamped in this gap.
