[0060] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0061] The following is a reference appendix. Figures 1-30 A door handle assembly 100 according to an embodiment of the present invention is described.

[0062] Reference Figure 1 , Figure 24 and Figure 25 According to the present invention, a door handle assembly 100 includes a handle body 10 and an unlocking mechanism 20. The handle body 10 facilitates the pulling of the hand on the door, and the unlocking mechanism 20 is connected to the handle body 10. Pulling the handle body 10 unlocks the unlocking mechanism 20, thereby allowing the door to be opened.

[0063] Specifically, the unlocking mechanism 20 includes an unlocking linkage 21, an unlocking crank 22, and an unlocking shaft 23. One end of the unlocking linkage 21 (e.g., Figure 1 The rear end of the handle body 10 shown is hinged to the handle body 10, and the other end of the unlocking linkage 21 (as shown) is... Figure 1 The front end of the handle body 10 shown is hinged to one end of the unlocking crank 22, and the other end of the unlocking crank 22 (as shown) is hinged to the front end of the handle body 10. Figure 1 The front end of the unlocking crank 22 shown is connected to the unlocking shaft 23. The handle body 10 drives the unlocking shaft 23 to rotate through the unlocking mechanism 20 to unlock the car door.

[0064] For example, such as Figure 1 , Figure 24 and Figure 25 As shown, taking the left-side door handle assembly 100 of the vehicle as an example, the handle body 10 is rectangular, with both the front and rear ends of the handle body 10 protruding to the right to facilitate hand insertion. When the handle body 10 is connected to the unlocking mechanism 20, the rear end of the unlocking linkage 21 is hinged to the rear end of the handle body 10, the rear end of the unlocking crank 22 is connected to the front end of the unlocking linkage 21, and the front end of the unlocking crank 22 is connected to the unlocking pivot 23.

[0065] When the door handle assembly 100 of this embodiment is pulled, taking the door handle assembly 100 on the left side of the vehicle as an example, the palm is inserted into the back of the handle body 10 and the handle body 10 is pulled to the left. The handle body 10 rotates, causing the unlocking linkage 21 to rotate. The unlocking linkage 21 causes the unlocking crank 22 to rotate. The unlocking crank 22 causes the unlocking shaft 23 to rotate. The unlocking shaft 23 rotates and pulls the unlocking rope, and the door opens.

[0066] In the prior art, the unlocking mechanism 20 and the handle body 10 are not completely constrained. When the unlocking is not complete, the connection between the unlocking mechanism 20 and the handle body 10 will collide with each other and produce abnormal noise. At the same time, when the unlocking linkage 21 in the unlocking mechanism 20 is connected to the unlocking lever 30, the protruding wall of the unlocking lever 30 will lock the unlocking linkage 21 inside the protruding wall. During the unlocking process, the unlocking linkage 21 will rub against the protruding wall of the unlocking lever 30 and produce friction noise. At the same time, when the handle body 10 rotates a large range, the end of the unlocking pull will hit the protruding wall of the unlocking lever 30 and produce impact noise.

[0067] The door handle assembly 100 of the present invention is provided with an unlocking mechanism 20 hinged to the handle body 10, and an unlocking linkage 21, an unlocking crank 22, and an unlocking shaft 23 hinged to each other. The hinged connections between the components only involve relative rotation. During the unlocking operation, the handle body 10 and the unlocking mechanism 20, as well as the unlocking linkage 21, the unlocking crank 22, and the unlocking shaft 23, will not collide with each other and produce abnormal noise, nor will they rub against each other and produce abnormal noise. This can effectively prevent collision noise and friction noise between the components, thereby improving the user experience. At the same time, avoiding mutual collision between the unlocking mechanisms 20 can also enhance the durability of the components and increase their service life. In addition, the rotation of the handle body 10 can drive the unlocking shaft 23 to rotate normally, thereby ensuring that the door can be opened normally.

[0068] According to an embodiment of the present invention, the door handle assembly 100 is provided with an unlocking mechanism 20 hinged to the handle body 10, and an unlocking linkage 21, an unlocking crank 22, and an unlocking shaft 23 hinged to each other. This can effectively prevent impact noise and friction noise, improve the user experience, and also increase the service life of the components. In addition, it can ensure that the unlocking shaft 23 of the unlocking mechanism 20 can rotate normally, thereby ensuring that the door can be opened normally.

[0069] According to some embodiments of the present invention, with reference to Figure 1 and Figure 24 A lever 30 is fitted onto the unlocking shaft 23, and the other end of the unlocking crank 22 (such as...) Figure 1 The left end of the unlocking crank 22 (as shown) is hinged to the lever 30. Thus, the unlocking shaft 23 and the unlocking crank 22 are connected by the lever 30. The lever 30 rotates with the unlocking crank 22, driving the unlocking shaft 23 to rotate, thereby ensuring the normal unlocking of the vehicle.

[0070] According to some optional embodiments of the present invention, refer to Figure 24 and Figure 28 The lever 30 may include a sleeve 31 and connecting posts 32. The sleeve 31 is cylindrical and is fitted and fixed on the unlocking shaft 23. There are two connecting posts 32, which are aligned along the axial direction of the sleeve 31 (e.g., ...). Figure 24The two connecting posts 32 are arranged at intervals in the vertical direction shown, and each of them has a first shaft hole 321 extending axially along the sleeve 31. The other end of the unlocking crank 22 (as shown) Figure 24 The front end of the unlocking crank 22 shown is provided with a first mating shaft 221, and the two ends of the first mating shaft 221 (such as...) Figure 24 The upper and lower ends of the first mating shaft 221 shown can respectively extend into the first shaft holes 321 of the two connecting posts 32. In this way, the lever 30 is axially hinged to the unlocking crank 22 through the connecting posts 32. There are no movable components between the unlocking mechanism 20 and the lever 30. During the door unlocking process, the generation of impact noise can be effectively prevented, thereby further improving the user experience.

[0071] For example, such as Figure 24 As shown, the sleeve 31 extends vertically. A seventh through hole 311, extending vertically through the middle of the sleeve 31, is provided. Two symmetrically arranged connecting posts 32 are provided at the upper and lower ends of the sleeve 31. A first shaft hole 321 is located at the rear end of the connecting post 32 and extends vertically through it. When the unlocking crank 22 is connected to the lever 30, the first mating shaft 221 of the unlocking crank 22 engages with the rear end of the lever 30. The fifth through hole 2211 and the first shaft hole 321 correspond vertically. A pin passes through the fifth through hole 2211 and the first shaft hole 321 to fix the first mating shaft 221 to the lever 30. The first mating shaft 221 can rotate relative to the lever 30.

[0072] According to some embodiments of the present invention, with reference to Figure 29 At one end of the unlocking linkage 21 (e.g.) Figure 29 The rear end of the unlocking linkage 21 shown faces the other end (as shown). Figure 29 In the direction of the front end of the unlocking linkage 21 shown, the unlocking linkage 21 extends along a zigzag or curve that protrudes toward the side where the handle body 10 is located, that is, as shown... Figure 29 As shown, the middle part of the unlocking link 21 protrudes towards the handle body 10. The protruding part of the unlocking link 21 can be a zigzag protrusion or a curved protrusion. This reduces the space occupied by the unlocking link 21 in the length direction, thereby reducing the space occupied by the unlocking mechanism 20 and providing more installation space for other components.

[0073] According to some embodiments of the present invention, with reference to Figure 3 , Figure 4 The unlocking hinge 23 can rotate between the locked and unlocked positions. When the unlocking hinge 23 is in the locked position, the door is locked; when the unlocking hinge 23 is in the unlocked position, the door is unlocked. This ensures that the door can be opened and closed normally.

[0074] Furthermore, such as Figure 3 , Figure 4As shown, the unlocking mechanism 20 may further include a first reset member connected to the unlocking shaft 23, which can drive the unlocking shaft 23 back to the locked position. Thus, after unlocking, the first reset member pulls the unlocking mechanism 20 to the locked position, locking the door. Preferably, the first reset member is a torsion spring, which is simple in structure and inexpensive.

[0075] For example, such as Figure 4 As shown, taking the door handle assembly 100 on the left side of the vehicle as an example, when the palm pulls the handle body 10, the handle body 10 rotates clockwise around the first end 11. The handle body 10 drives the unlocking shaft 23 to rotate clockwise. The unlocking shaft 23 rotates until it is in the unlocked position. At the same time, the clockwise rotation of the unlocking shaft 23 will cause the first reset member to deform and generate elastic force. When the door is unlocked, the palm is released, and the first reset member releases the elastic force and pulls the unlocking shaft 23 to rotate counterclockwise until the unlocking shaft 23 is in the locked position.

[0076] According to some embodiments of the present invention, with reference to Figure 1 , Figure 3 and Figure 4 Handle body 10 along the first direction (e.g.) Figure 1 The handle body 10 (as shown in the left and right directions) can move between the hidden position and the extended position, and the handle body 10 is movable in the length direction (e.g., in the left and right directions). Figure 1 The handle body 10 shown has two ends on its front and rear sides (as shown) respectively, namely the first end 11 (e.g., Figure 1 The front end of the handle body 10 shown) and the second end 12 (as shown) Figure 1 (The rear end of the handle body 10 shown). When the handle body 10 needs to be pulled to open the car door, the handle body 10 is in the extended position, making it convenient to pull the handle body 10. When the handle body 10 does not need to be pulled, the handle body 10 is in the hidden position, which can improve the aesthetics of the vehicle.

[0077] Furthermore, such as Figure 1 , Figure 3 and Figure 4 As shown, the door handle assembly 100 also includes a drive member 40, a first transmission mechanism 50, and a second transmission mechanism 60. The drive member 40 is connected to the first end 11 via the first transmission mechanism 50 to push the first end 11 to move, and abuts against the second end 12 via the second transmission mechanism 60 to push the second end 12 to move, thereby enabling the handle body 10 to move between a concealed position and an extended position. Thus, the handle body 10 can move between the concealed position and the extended position. Furthermore, the first transmission mechanism 50 is connected to the first end 11, and the first transmission mechanism 50 and the handle body 10 have a stable hinged connection structure. When the handle body 10 is in the extended or retracted state, this increases the strength of the door handle assembly 100 in the left-right and up-down directions, preventing the handle body 10 from being damaged during extension or retraction.

[0078] When the handle body 10 needs to be pulled, taking the left-side door handle assembly 100 as an example, the drive member 40 drives the first transmission mechanism 50 to move, the first transmission mechanism 50 drives the second transmission mechanism 60 to move, and the first transmission mechanism 50 and the second transmission mechanism 60 together push the handle body 10 from the hidden position to the left and then to the extended position. When the handle body 10 does not need to be pulled, the drive member 40 drives the first transmission mechanism 50 to move, the first transmission mechanism 50 drives the second transmission mechanism 60 to move, and the first transmission mechanism 50 and the second transmission mechanism 60 together pull the handle body 10 from the extended position to the right and then to the hidden position.

[0079] For example, such as Figure 12 As shown, the driving component 40 includes a motor 41 and a drive shaft 42. The rotation of the motor 41 drives the drive shaft 42 to rotate, and the drive shaft 42 drives the first transmission mechanism 50 to rotate.

[0080] According to some optional embodiments of the present invention, refer to Figure 11 , Figure 14 and Figure 15 The first transmission mechanism 50 includes: a first drive rod 51, a first crank 52, a first connecting rod 53, and a first slider 54. The driving member 40 is connected to the first drive rod 51 to drive the first drive rod 51 to rotate; one end of the first crank 52 (e.g., ...) Figure 9 The rear end of the first crank 52 shown is fixed to the first drive rod 51; one end of the first connecting rod 53 (as shown) Figure 9 The rear end of the first connecting rod 53 (as shown) and the other end of the first crank 52 (as shown) Figure 9 The front end of the first crank 52 shown is rotatably connected; the other end of the first slider 54 is connected to the other end of the first connecting rod 53 (as shown). Figure 9 The first connecting rod 53 shown is rotatably connected to the front end of the first connecting rod 53, and the first slider 54 is along the first direction (e.g., Figure 13 (As shown in the left and right directions) can slide and is connected to the first end 11.

[0081] In this way, the rotation of the driving component 40 drives the first driving rod 51 to rotate, the first driving rod 51 drives the first crank 52 to rotate around the first driving rod 51, the first crank 52 drives the first connecting rod 53 to rotate, and the first connecting rod 53 rotates around the connection between the first connecting rod 53 and the first crank 52. The first connecting rod 53 drives the first slider 54 to move, and the first slider 54 pushes the first end 11 of the handle body 10 to move to the left or right. Under the action of the driving component 40, the handle body 10 is pushed out or pulled back. In addition, the first slider 54 and the first connecting rod 53 can only rotate relative to each other and cannot move relative to each other. This reduces the moving pairs of the first transmission mechanism 50, thereby improving the stability of the movement of the first transmission mechanism 50.

[0082] For example, such as Figure 14 , Figure 15 , Figure 16 , Figure 17 and Figure 18 As shown, the first drive rod 51 is cylindrical and extends vertically. A coupling 55 is connected to the lower end of the first drive rod 51. The first crank 52 extends horizontally. The rear end of the first crank 52 is annular, with an eighth through hole 521 penetrating vertically through the center of the annulus. The front end of the first crank 52 is elongated, with a ninth through hole 522 penetrating vertically through the front end. The first connecting rod 53 is arranged from left front to right rear. Two first connecting arms 531 are located at the right rear end of the first connecting rod 53. The first drive rod 51 is arranged at intervals along the vertical direction of the first connecting rod 53, and the first connecting arm 531 has a tenth through hole 5311 that runs through the first connecting arm 531 in the vertical direction. The middle of the two first connecting arms 531 forms the mounting space for the first crank 52. The left front end of the first connecting rod 53 has an eleventh through hole 532 that runs through the first connecting rod 53 in the vertical direction. The first slider 54 is arranged in the left-right direction and is rectangular in the vertical direction. The right end of the first slider 54 has a groove in the middle, and the left end of the first slider 54 has a hinge through hole 542 that runs through the first slider 54 in the vertical direction. Preferably, the first drive rod 51 and the first slider 54 are formed by injection molding, which can improve production efficiency.

[0083] When the drive unit 40, the first transmission mechanism 50 and the handle body 10 are connected, the left end of the first slider 54 is hinged to the right side of the first end 11 of the handle body 10, the right end of the first slider 54 is connected to the first connecting rod 53, the left front end of the first connecting rod 53 is inserted into the groove at the right end of the first slider 54, the right rear end of the first connecting rod 53 is connected to the first crank 52, the front end of the first crank 52 is inserted into the space defined by the two connecting arms at the right rear end of the first connecting rod 53, and the ninth through hole 522 and the tenth through hole 5311 correspond in the vertical direction, the rear end of the first crank 52 is connected to the first drive rod 51 and the first drive rod 51 passes through the eighth through hole 521 at the rear end of the first crank 52, and the lower end of the first drive rod 51 is connected to the drive shaft 42 of the drive unit 40 through the coupling 55.

[0084] According to some optional embodiments of the present invention, refer to Figure 11 , Figure 19 and Figure 20 The second transmission mechanism 60 includes: a second drive rod 61, a second crank 62, a second connecting rod 63, and a second slider 64. The driving member 40 is connected to the second drive rod 61 to drive the second drive rod 61 to rotate; one end of the second crank 62 (e.g., ...) Figure 9 The front end of the second crank 62 shown is fixed to the second drive rod 61; one end of the second connecting rod 63 (as shown) Figure 9The front end of the second connecting rod 63 (as shown) and the other end of the second crank 62 (as shown) Figure 9 The rear end of the second crank 62 shown is rotatably connected; the other end of the second slider 64 is connected to the other end of the second connecting rod 63 (as shown). Figure 9 The rear end of the second link 63 shown is rotatably connected, and the second slider 64 is along the first direction (e.g., Figure 18 (As shown in the left and right directions) can slide and is adapted to abut against the second end 12.

[0085] In this way, the rotation of the driving component 40 drives the first driving rod 51 to rotate, the first driving rod 51 drives the second driving rod 61 to rotate, the second driving rod 61 drives the second crank 62 to rotate around the second driving rod 61, the second crank 62 drives the second connecting rod 63 to rotate, and the second connecting rod 63 rotates around the connection between the second connecting rod 63 and the second crank 62. The second connecting rod 63 drives the second slider 64 to move, and the second slider 64 pushes the second end 12 of the handle body 10 to move. Under the action of the driving component 40, the handle body 10 is pushed out. In addition, the second slider 64 and the second connecting rod 63 can only rotate relative to each other and cannot move relative to each other. This reduces the moving pairs of the second transmission mechanism 60, thereby improving the stability of the movement of the second transmission mechanism 60.

[0086] For example, such as Figure 19 , Figure 20 , Figure 21 , Figure 22 and Figure 23 As shown, the second drive rod 61 is cylindrical and extends vertically, the second crank 62 extends horizontally, the front end of the second crank 62 is annular and has a twelfth through hole 621 in the middle of the annulus, and the rear end of the second crank 62 is elongated and bends in the middle away from the handle body 10. The rear end of the second crank 62 has a thirteenth through hole 622 in the vertical direction. The second connecting rod 63 is arranged from left rear to right front. The front end is provided with two second connecting arms 631, which are spaced apart along the vertical direction of the second connecting rod 63. Each second connecting arm 631 has a fourteenth through hole 6311 extending vertically through it. The middle of the two second connecting arms 631 forms the mounting space for the second crank 62. The left rear end of the second connecting rod 63 has a fifteenth through hole 632 extending vertically through it. The second slider 64 is arranged horizontally and is rectangular in shape vertically. A groove is provided in the middle of the right end of the second slider 64. Preferably, the second drive rod 61 and the second slider 64 are formed by injection molding, which can improve production efficiency.

[0087] When the second transmission mechanism 60 and the handle body 10 are connected, the left end of the second slider 64 abuts against the right side surface of the second end 12 of the handle body 10, the right end of the second slider 64 is connected to the second connecting rod 63, the left rear end of the second connecting rod 63 is inserted into the groove at the right end of the second slider 64, the right front end of the second connecting rod 63 is connected to the second crank 62, the rear end of the second crank 62 is inserted into the space defined by the two connecting arms at the right front end of the second connecting rod 63, and the thirteenth through hole 622 and the fourteenth through hole 6311 correspond in the vertical direction, the second crank 62 is connected to the second drive rod 61, and the second drive rod 61 passes through the twelfth through hole 621 at the front end of the second crank 62.

[0088] According to some optional embodiments of the present invention, refer to Figure 7 , Figure 10 , Figure 18 and Figure 23 The door handle assembly 100 may further include: a mounting housing 70, a drive component 40, a first transmission mechanism 50, and a second transmission mechanism 60, all disposed within the mounting housing 70. The mounting housing 70 contains a first guide groove 74 and a second guide groove 75 extending in a first direction. A first guide block 541 is provided on the first slider 54, engaging with the first guide groove 74. A second guide block 641 is provided on the second slider 64, engaging with the second guide groove 75. Thus, the first guide groove 74 guides the movement of the first slider 54, and the second guide groove 75 guides the movement of the second slider 64, thereby limiting the direction of movement of the handle body 10 and ensuring that the handle body 10 moves along a preset direction. Simultaneously, the first guide groove 74 and the second guide groove 75 guide the movement of the first slider 54 and the second slider 64, ensuring precise movement of the first slider 54 and the second slider 64.

[0089] For example, such as Figure 10 , Figure 18 and Figure 23 As shown, two first guide grooves 74 are provided at the front end of the mounting shell 70, spaced apart vertically. Two second guide grooves 75 are provided at the rear end of the mounting shell 70, also spaced apart vertically. Two first guide blocks 541 are rectangular, one on the upper surface of the first slider 54 and the other on the lower surface. Two second guide blocks 641 are rectangular, one on the upper surface of the second slider 64 and the other on the lower surface. Preferably, the mounting shell 70 is formed by injection molding, which improves production efficiency.

[0090] According to some embodiments of the present invention, with reference to Figure 11 and Figure 13 The door handle assembly 100 may further include: a first gear 81 and a second gear 82 that mesh with each other. The first gear 81 is coaxially fixed to the first drive rod 51, and the second gear 82 is coaxially fixed to the second drive rod 61. A drive member 40 is connected to the first drive rod 51, and the drive member 40 drives the second drive rod 61 to rotate through the first drive rod 51, the first gear 81, and the second gear 82. Thus, the rotation of the drive member 40 can control the rotation of the first drive rod 51 and the second drive rod 61, ensuring that the first end 11 and the second end 12 of the handle body 10 are pushed out in parallel, realizing the parallel movement of the entire handle body 10.

[0091] For example, such as Figure 11 and Figure 13 As shown, the first gear 81 has a sixteenth through hole 811 extending vertically through the first gear 81, and the second gear 82 has a seventeenth through hole 821 extending vertically through the second gear 82. The first gear 81 is sleeved on the first drive rod 51 and passes through the sixteenth through hole 811. The second gear 82 is sleeved on the second drive rod 61 and passes through the seventeenth through hole 821. The first gear 81 and the second gear 82 mesh with each other. Taking the left door handle assembly 100 of a vehicle as an example, when the handle body 10 is pushed out from the hidden position to the pushed-out position, the drive member 40 drives the first drive rod 51 to rotate counterclockwise. The first gear 81 follows the first drive rod 51 to rotate counterclockwise. The first gear 81 drives the second gear 82 to rotate clockwise. The second gear 82 drives the second drive rod 61 to rotate clockwise. The first drive rod 51 drives the first slider 54 to move to the left, and the second drive rod 61 drives the second slider 64 to move to the left. The first slider 54 and the second slider 64 together move the handle body... When the handle body 10 is pushed out to the pushed-out position and pulled back to the hidden position, the drive member 40 drives the first drive rod 51 to rotate clockwise. The first drive rod 51 drives the first slider 54 to move to the right. At the same time, the first gear 81 follows the first drive rod 51 to rotate clockwise, driving the second gear 82 to rotate counterclockwise. The second gear 82 drives the second drive rod 61 to rotate counterclockwise, and the second drive rod 61 drives the second slider 64 to move to the right. Thus, the first slider 54 and the second slider 64 pull the handle body 10 back to the hidden position.

[0092] According to some embodiments of the present invention, with reference to Figure 11 and Figure 13 Both the first gear 81 and the second gear 82 are toothless gears. This reduces the weight of the door handle assembly 100 and lowers manufacturing costs. At the same time, with the weight of the first gear 81 and the second gear 82 reduced, the handle body 10 can be pushed out or pulled back without the need for a high-power drive component 40, which can reduce the manufacturing cost of the drive component 40.

[0093] For example, such as Figure 13 As shown, the angle between the two ends of the teeth of the first gear 81 in the circumferential direction and the line connecting them to the center of the circle is 100°-120°, and the angle between the two ends of the teeth of the second gear 82 in the circumferential direction and the line connecting them to the center of the circle is 100°-120°. This ensures that the first gear 81 and the second gear 82 can mesh normally within the rotation range, while also reducing the weight of the first gear 81 and the second gear 82.

[0094] According to some embodiments of the present invention, with reference to Figure 3 and Figure 5 The handle body 10 is rotatable relative to the first slider 54 between the initial position and the emergency unlock position. In the initial position, the first end 11 and the second end 12 are perpendicular to the first direction (e.g., Figure 3 The second direction (as shown in the front and back directions) Figure 3 The second end 12 is aligned with the first end 11 in the left-right direction (as shown). In the emergency unlock position, the second end 12 is offset from the first end 11 in the second direction, and the second slider 64 is separated from the second end 12. Thus, in an emergency, the second end 12 of the handle body 10 assembly can be lifted to facilitate opening the door.

[0095] For example, such as Figure 5 As shown, taking the door handle assembly 100 on the left side of the vehicle as an example, when an emergency unlocking is needed, press the first end 11 and the second end 12 will tilt to the left to open the door.

[0096] Furthermore, such as Figure 5 As shown, the door handle assembly 100 also includes a second reset member, which is connected between the first slider 54 and the first end 11. The second reset member can drive the handle body 10 to rotate to the initial position. Thus, after an emergency unlock, the second reset member releases the force that drove the handle body 10 to rotate to the initial position, allowing the handle body 10 to return to the hidden position.

[0097] For example, such as Figure 5 As shown, the second reset component is a reset torsion spring. During emergency unlocking, the reset torsion spring stores elastic force. After the emergency unlocking is completed, the drive motor 41 rotates clockwise, and the first slider 54 pulls the first end 11 of the handle body 10 to move to the right. At the same time, the reset torsion spring releases its elastic force and pulls the second end 12 of the handle body 10 to move to the right, so that the first end 11 and the second end 12 of the handle body 10 maintain the same speed.

[0098] A vehicle according to a second aspect of the present invention includes a door handle assembly 100 according to the first aspect of this embodiment.

[0099] According to an embodiment of the present invention, by providing the door handle assembly 100 of the first aspect embodiment, the unlocking mechanism 20 is hingedly connected to the handle body 10, and the unlocking linkage 21, unlocking crank 22 and unlocking shaft 23 are hingedly connected to the door handle assembly 100. This can effectively prevent the generation of impact noise and friction noise, improve the user experience, and also increase the service life of the components. In addition, it can ensure that the unlocking shaft 23 of the unlocking mechanism 20 can rotate normally, thereby ensuring that the door can be opened normally.

[0111] The driving component 40 includes a motor 41 and a drive shaft 42. The motor 41 drives the drive shaft 42 to rotate, and the drive shaft 42 is connected to the first drive rod 51 through a coupling 55.

[0112] The first gear 81 is provided with a sixteenth through hole 811, and the first drive rod 51 is sleeved in the sixteenth through hole 811. The first gear 81 and the first drive rod 51 rotate coaxially. The second gear 82 is provided with a seventeenth through hole 821, and the second drive rod 61 is sleeved in the seventeenth through hole 821.

[0113] The mounting housing 70 has the following features: a first drive rod through hole 71, a second drive rod through hole 72, an unlocking shaft through hole 73, a first guide groove 74, and a second guide groove 75.

[0114] When assembling the door handle assembly 100, first assemble the drive component 40, the first gear 81, the second gear 82, the first transmission mechanism 50, and the second transmission mechanism 60. First, mount the first gear 81 onto the first drive rod 51, and mount the second gear 82 onto the second drive rod 61. Then, connect the drive shaft 42 to the motor 41. The drive shaft 42 is connected to the lower end of the first drive rod 51 through the coupling 55. Then, install the second gear 82 on the rear side of the first gear 81 and mesh with the first gear 81. Then, install the upper and lower ends of the first drive rod 51 into the first drive rod through hole 71 on the mounting housing 70. The first slider 54 connects to the first end 11 of the handle body 10, and the hinge through hole 542 corresponds to the hinge hole 13 in the vertical direction. The first guide block 541 fits in the first guide groove 74. The upper and lower ends of the second drive rod 61 are installed in the second drive rod through hole 72 on the mounting housing 70. The second slider 64 abuts against the right side surface of the second end 12, and the second guide block 641 fits in the second guide groove 75. Finally, the upper and lower ends of the unlocking shaft 23 of the unlocking mechanism 20 are installed in the unlocking shaft through hole 73. The first rod 211 and the third rod 213 of the unlocking linkage 21 lock the connecting part 15 of the handle body 10 in the limited space at the rear end of the first rod 211 and the third rod 213. The connecting hole 151 corresponds to the through hole at the rear end of the first rod 211 and the third rod 213. The pin passes through the connecting hole 151 and the through hole at the rear end of the unlocking linkage 21. The connecting part 15 is hinged to the unlocking linkage 21. At this time, the door handle assembly 100 is assembled.

[0115] When the car door needs to be opened, taking the left-side door handle assembly 100 as an example, the motor 41 drives the drive shaft 42 to rotate clockwise. The drive shaft 42 drives the first drive rod 51 to rotate clockwise, and the first gear 81 follows the first drive rod 51 to rotate clockwise. The first drive rod 51 drives the first slider 54 to move to the left. The first slider 54 pushes the first end 11 of the handle body 10 to move to the left. At the same time, the second gear 82 meshes with the first gear 81, causing the second gear 82 to rotate counterclockwise. The second gear 82 drives the second drive rod 61 to rotate counterclockwise, and the second drive rod 61 drives the second slider 64 to move to the left. The second slider 64 pushes the second end 12 of the handle body 10 to move to the left. The first slider 54 and the second slider 64 simultaneously push the handle body 10 to the left in parallel until the handle body 10 is pushed out from the hidden position to the pushed-out position. At this time, the handle body 10 is pushed out. The occupant inserts their hand into the handle body 10 and pulls the handle body 10. Figure 5 As shown, the second end 12 of the handle body 10 rotates clockwise around point C of the first end 11 of the handle body 10. Point C of the first end 11, point B on the lever 30, point D of the unlocking shaft 23, and point A of the unlocking link 21 form a four-bar linkage. This four-bar linkage will cause the BD rod to rotate around D. At this time, the unlocking link 21 rotates, and the unlocking link 21 drives the unlocking shaft 23 to rotate clockwise from the locked position to the unlocked position. The unlocking shaft 23 pulls the unlocking cord, and the door unlocks. At the same time, the rotation of the unlocking shaft 23 causes the first reset member to store elastic force. When the unlocking is completed, the hand is released, and the first reset member releases the elastic force and pulls the unlocking shaft 23 to rotate in the opposite direction until the unlocking shaft 23 is in the locked position. Then, the motor 41 drives the drive shaft 42 to rotate counterclockwise. The drive shaft 42 drives the first drive rod 51 to rotate counterclockwise. The first drive rod 51 drives the first slider 54 to move to the right. The first slider 54 pulls the handle body 10 to move to the right until the handle body 10 reaches the hidden position.

[0116] When an emergency unlock is required, taking the door handle assembly 100 on the left side of the vehicle as an example, press the left surface of the first end 11 of the handle body 10, and the second end 12 of the handle body 10 rotates clockwise around point C of the first end 11 of the handle body 10 until the handle body 10 moves from the initial position to the emergency unlock position. The rotation of the handle body 10 causes the second reset member to store spring force. At the same time, the rotation of the handle body 10 drives the unlocking shaft 23 to rotate, and the unlocking shaft 23 pulls the unlocking rope, opening the door. After releasing the hand, the second reset member releases the spring force, causing the door handle assembly 100 to return from the emergency unlock position to the initial position. Then the motor 41 runs, pulling the handle body 10 to the hidden position.

[0117] The vehicle of the present invention includes a door handle assembly 100. The unlocking mechanism 20 is hinged to the handle body 10, and the unlocking linkage 21, unlocking crank 22, and unlocking shaft 23 are also hinged to the door handle assembly 100. This effectively prevents impact and friction noises, improves the user experience, and extends the service life of the components. Furthermore, the hinged connection between the handle body 10 and the unlocking mechanism 20 ensures that the force exerted by the handle body 10 on the unlocking linkage 21 is symmetrical, guaranteeing the normal rotation of the unlocking shaft 23 of the unlocking mechanism 20 and thus ensuring the normal opening of the door.
