Description

Technical Field

[0001] The present invention relates to the technical field of automobile accessories, and in particular to an automobile door lock unlocking structure, a driving device and a method. Background Art

[0002] The door unlocking actuator is a core component of the vehicle's door opening and closing system. Its primary function is to mechanically or electronically convert the driver or passenger's operating instructions into unlocking motion, enabling the door to open smoothly. A typical device consists of a handle, cable, switch, base, trim, and other related components. Rotating or swinging the handle drives the cable, triggering the door unlocking mechanism. Appropriate positioning, securing, and return mechanisms are also required to ensure a smooth, accurate, and stable unlocking process, safeguarding vehicle safety and the user experience.

[0003] However, the existing automobile door lock unlocking drive device has the following technical problems: First, the matching of the handle rotation angle and the door cable stroke is not accurate enough, which may easily lead to the mechanical unlocking timing not meeting the design standards and affecting the unlocking reliability. Second, the triggering timing of the switch signal is difficult to control accurately, and it is impossible to ensure that it is triggered at the appropriate handle rotation angle, which in turn affects the vehicle electronic system's accurate recognition and response to the door status. Third, there is a lack of effective control measures for the handle return speed, which may easily cause the handle to return too fast or too slow, reducing the user experience and possibly causing damage to components due to collision. Fourth, the assembly and fixing structure of the handle assembly and the trim panel, the handle base and the lower cover, the handle base and the speaker metal cover, the handle assembly and the speaker are not optimized enough. After long-term use, they may become loose or displaced, affecting the overall stability and reliability of the equipment, and even causing abnormal noise or functional failure. Summary of the Invention

[0004] The purpose of the present invention is to provide a car door lock unlocking structure, driving device and method, aiming to solve the problem that the existing door handle has a long operating stroke and a large rebound impact, which causes the components to be easily damaged.

[0005] To achieve the above objectives, in a first aspect, the present invention provides a vehicle door lock unlocking actuation device, comprising a base, a switch assembly, and a drive mechanism, wherein the drive mechanism comprises a pin, a handle, a torsion spring, a cable, and a damping assembly;

[0006] The switch assembly is installed on the base, the pin is installed on the base, the handle is installed on the pin, the torsion spring is sleeved on the pin, the pull wire is fixedly connected to the base, and its output end is connected to the handle, and the damping component is installed between the handle and the base.

[0007] Wherein, the driving mechanism further includes a buffer pad, which is fixedly connected to the base and is located on a side of the base close to the handle.

[0008] Wherein, the driving mechanism also includes a blocking cover, which has a plurality of buckles 1, and the plurality of buckles 1 are respectively fixedly connected to the blocking cover and are respectively located on the blocking cover, and the blocking cover is clamped on the base through the plurality of buckles 1.

[0009] Wherein, the base has a plurality of wire harness buckles, and the plurality of wire harness buckles are respectively fixedly connected to the base and connected to the switch assembly, and are respectively located on the base.

[0010] Wherein, the driving mechanism also includes a mesh cover, the mesh cover has a plurality of buckles 2, the plurality of buckles 2 are respectively fixedly connected to the mesh cover and are respectively located on the mesh cover, and the mesh cover is clamped to the base through the plurality of buckles.

[0011] In a second aspect, a vehicle door lock unlocking structure is driven by the vehicle door lock unlocking driving device described in the first aspect.

[0012] In a third aspect, a method for unlocking a vehicle door lock is provided, which is used in the vehicle door lock unlocking device described in the first aspect, and comprises the following steps:

[0013] The user rotates the handle to drive the pin to rotate, and the handle triggers the switch signal of the switch assembly to unlock the door, while the pull wire limits the rotation angle of the handle;

[0014] Release the handle, and the handle returns to its original position under the action of the torsion spring, completing the unlocking. The damping component slows down the handle's return speed, and all components return to their initial state.

[0015] The present invention relates to a vehicle door lock unlocking actuation device. The base provides mounting conditions for the switch assembly and the drive mechanism. To unlock the vehicle door lock, the user pulls the handle with external force, causing it to rotate about the pin. The torsion spring is compressed to store energy. Simultaneously, the pull wire connected to the handle output generates tension due to the handle rotation, converting the rotational motion into linear motion and transmitting the driving force to the switch assembly. During the handle rotation, the damping component controls the handle's movement speed through a damping effect, preventing mechanical impact caused by overly rapid operation. When the handle rotates to its extreme position, the switch assembly is triggered to unlock the door. After the user releases the handle, the torsion spring releases its compressed energy, driving the handle to rotate in the opposite direction around the pin and reset. At this point, the damping component intervenes again, slowing the handle's reset speed through damping force, preventing rigid collision between the handle and the base. This solves the problem of existing door handles, which suffer from long operating strokes and large rebound impacts that can lead to component damage. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The following describes embodiments of the present invention in detail, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent 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 intended to be used to explain the present invention, and are not to be construed as limiting the present invention.

[0023] See also Figures 1 to 3 In a first aspect, the present invention provides a vehicle door lock unlocking drive device, comprising a base 1, a switch assembly 2, and a drive mechanism, wherein the drive mechanism comprises a pin 3, a handle 4, a torsion spring 5, a pull wire 6, and a damping assembly 7;

[0024] The switch assembly 2 is installed on the base 1, the pin 3 is installed on the base 1, the handle 4 is installed on the pin 3, the torsion spring 5 is sleeved on the pin 3, the pull wire 6 is fixedly connected to the base 1, and its output end is connected to the handle 4, and the damping component 7 is installed between the handle 4 and the base 1.

[0025] In this embodiment, the base 1 provides mounting support for the switch assembly 2 and the drive mechanism. To unlock the vehicle door lock, the user pulls the handle 4 externally, causing it to rotate about the pin 3. The torsion spring 5 is compressed and stores energy. Simultaneously, the pull wire 6 connected to the output end of the handle 4 generates tension due to the rotation of the handle 4, converting the rotational motion into linear motion and transmitting the driving force to the switch assembly 2. During the rotation of the handle 4, the damping assembly 7 controls the speed of the handle 4 through its damping effect, preventing mechanical shock caused by overly rapid operation. When the handle 4 rotates to its limit, the switch assembly 2 is triggered to unlock. When the user releases the handle 4, the torsion spring 5 releases its compressed energy, driving the handle 4 to rotate in the opposite direction around the pin 3 and return to its original position. At this point, the damping assembly 7 intervenes again, slowing the return of the handle 4 through its damping force, preventing a rigid collision between the handle 4 and the base 1. This solves the problem of existing door handles, which suffer from long operating strokes and significant rebound impact, leading to component damage.

[0026] Furthermore, the driving mechanism further includes a buffer pad 8 , which is fixedly connected to the base 1 and is located on a side of the base 1 close to the handle 4 .

[0027] In this embodiment, when the handle 4 is rotated to the extreme position, the buffer pad 8 contacts the end of the handle 4 and absorbs the collision energy through deformation of the flexible material, thereby further reducing vibration and noise.

[0028] Furthermore, the driving mechanism also includes a blocking cover 9, which has a plurality of buckles 10. The plurality of buckles 10 are respectively fixedly connected to the blocking cover 9 and are respectively located on the blocking cover 9. The blocking cover 9 is clamped on the base 1 through the plurality of buckles 10.

[0029] In this embodiment, the internal components of the drive mechanism are protected by the snap-fit ​​connection structure of the blocking cover 9. The blocking cover 9 prevents foreign matter from entering the mechanism.

[0030] Furthermore, the base 1 has a plurality of wire harness buckles 11 , which are respectively fixedly connected to the base 1 and connected to the switch assembly 2 , and are respectively located on the base 1 .

[0031] In this embodiment, the wiring harness of the switch assembly 2 can be limited and fixed by using the plurality of wiring harness buckles 11 .

[0032] Furthermore, the driving mechanism also includes a mesh cover 12, and the mesh cover 12 has multiple buckles 13. The multiple buckles 13 are respectively fixedly connected to the mesh cover 12 and are respectively located on the mesh cover 12. The mesh cover 12 is connected to the base 1 through the multiple buckles.

[0033] In this embodiment, the internal components of the drive mechanism are protected by the snap-fit ​​connection structure of the mesh cover 12. The mesh cover 12 provides dust and water resistance in scenarios where air permeability is required, ensuring the long-term reliability of the mechanism.

[0034] In a second aspect, a vehicle door lock unlocking structure is driven by the vehicle door lock unlocking driving device described in the first aspect.

[0035] See also Figure 4 In a third aspect, a method for unlocking a car door lock is provided, which is used in the car door lock unlocking drive device described in the first aspect, and comprises the following steps:

[0036] S1 The user rotates the handle 4 to drive the pin 3 to rotate, and the handle 4 triggers the switch signal of the switch assembly 2 to unlock the door. At the same time, the pull wire 6 limits the rotation angle of the handle 4;

[0037] Specifically, to unlock a vehicle door, the user pulls on handle 4 with external force, causing it to rotate about pin 3. The torsion spring 5 is compressed and stores energy. Simultaneously, the pull wire 6, connected to the output end of handle 4, generates tension due to the rotation of handle 4, converting rotational motion into linear motion, transmitting the driving force to the switch assembly 2. During the rotation of handle 4, the damping component 7 controls the speed of handle 4 through its damping effect, preventing mechanical shock caused by overly rapid operation. When handle 4 reaches its limit, it triggers switch assembly 2 to unlock the door.

[0038] S2 releases the handle 4, and the handle 4 returns to its original position under the action of the torsion spring 5, completing the unlocking. The damping component 7 slows down the return speed of the handle 4, and all components return to their initial state.

[0039] Specifically, after the user releases the handle 4, the torsion spring 5 releases the compressed energy and drives the handle 4 to rotate in the opposite direction around the pin 3 to reset. At this time, the damping component 7 intervenes again, delaying the reset speed of the handle 4 through the damping force to prevent the handle 4 from rigidly colliding with the base 1.

[0040] The above disclosure is merely a preferred embodiment of the automobile door lock unlocking structure, driving device and method of the present invention. It is certainly not intended to limit the scope of the present invention.
