Description

Technical Field

[0001] This invention relates to the field of automotive door interior armrests, specifically to an integrated electromechanical dual-mode automotive door inward-opening armrest system. Background Technology

[0002] In the current automotive door opening field, electronic door opening buttons are widely used. However, most electronic door opening buttons are located separately from mechanical emergency handles in different positions inside the door. Furthermore, the location, shape, and opening method of mechanical emergency handles are often difficult for customers to discover and identify, posing a significant safety hazard.

[0003] To address this issue, integrating electronic and mechanical functions has become an industry trend. However, applying such dual-mode integrated devices to space-constrained door handle systems presents a series of stringent engineering challenges: The armrest needs to accommodate both the integrated inward opening assembly and the window regulator switch module. Under the premise of ensuring that the lateral width of the armrest (Y direction of the vehicle) does not encroach on the cabin space, the arrangement and avoidance of the two in a small area is extremely difficult. When electronic buttons are placed on the side of the armrest, they are easily triggered by the knees of passengers, and a precise dimensional chain needs to be established to ensure the natural coordination of pressing to open the door and pushing the door. Mechanical handles require a specific motion envelope space when opened in an emergency, and the installation path and stroke verification of the inner opening cable are complicated within the compact handle cavity, resulting in low feasibility for mass production.

[0004] Therefore, there is an urgent need to develop a generalizable automotive door inward-opening handrail system that can comprehensively address ergonomics, structural avoidance, motion verification, and assembly feasibility. Summary of the Invention

[0005] To address the aforementioned problems, this invention proposes an integrated electromechanical dual-mode automotive door inward-opening armrest system, comprising: The door handle body includes a handle gripping area extending downward from the top and a finger operation cavity opened on the side wall; A dual-mode inward-opening assembly is arranged within the finger operating cavity. This assembly integrates an independently assembled electronic inward-opening button and a mechanical inward-opening handle. The mechanical inward-opening handle has a frame, and the touch surface of the electronic inward-opening button is embedded within the frame. The frame protrudes from the surface of the electronic inward-opening button, forming a physical protective outer edge. The back of the mechanical inward-opening handle is provided with a support structure and a spring-loaded stop. The spring-loaded stop is fixedly positioned behind the mechanical inward-opening handle's travel path towards the inner side of the door armrest, limiting the maximum inward travel of the mechanical inward-opening handle. At the maximum inward travel, the frame of the mechanical inward-opening handle and the electronic inward-opening button do not contact each other. The electronic inward-opening button is electrically connected to the vehicle door electronic control system to trigger an electronically controlled door opening signal. The mechanical inward-opening handle is mechanically connected to the door lock mechanism via a cable to mechanically open the door when the electronic inward-opening button fails. The window crank switch module is arranged on the door handle body; The dual-mode inward opening assembly and the window crank switch module are arranged along the length direction inside the door handle body. The projection of the dual-mode inward opening assembly along the length direction is spaced apart from the projection of the window crank switch module along the length direction. Alternatively, the two have an overlapping area along the length direction, and within the overlapping area, the internal structure of the dual-mode inward opening assembly and the internal structure of the window crank switch module are staggered in the width direction of the door handle body.

[0006] In one embodiment, using the X-coordinate position of the cross point of a 50% male human body model as the measurement reference, the geometric center of the electronic inward-opening button is no less than 300mm away from the measurement reference, and the foremost operating button of the window crank switch module is no more than 450mm away from the measurement reference.

[0007] In one embodiment, the handrail gripping area is a groove structure extending downward from the top of the door handrail body, the top opening width of the groove structure is 25mm to 35mm, and the depth of the groove structure in the height direction of the door handrail body is 40mm to 60mm. The inner wall of the groove structure is a concave curved surface that slopes outward toward the outside of the vehicle. The outside of the vehicle is the side away from the interior of the vehicle. The concave curved surface is configured as a contoured structure that conforms to the gripping posture of fingers, and the bottom area of ​​the groove structure forms a storage space for small objects.

[0008] In one embodiment, within the overlapping area, the internal structure of the window crank switch module is offset in the width direction toward the inside or outside of the door handle body to avoid the finger operation cavity, so that the maximum grip width of the door handle body in the overlapping area does not exceed 75mm, where the maximum grip width refers to the maximum external dimension of the door handle body in the width direction.

[0009] In one embodiment, the vertical height from the geometric center of the electronic inward-opening button to the top surface of the door handle body does not exceed 50mm; The height position area of ​​the electronic inner opening button and the depth position area of ​​the handrail gripping area are arranged in a spatially opposite manner on the inner and outer sides of the door handrail body, so as to configure a synchronous and coordinated force exertion structure for thumb pressing and other fingers gripping.

[0010] In one embodiment, the mechanical inward-opening handle is rotatably hinged to the inside of the door handle body via a pivot, and the pivot is arranged adjacent to the side edge of the electronic inward-opening button; The limit rotation angle for the mechanical inward opening handle to open toward the inside of the vehicle is configured to be in the range of 45° to 55°; during the movement from the initial closed position to the limit rotation angle, the maximum rotational envelope width of the mechanical inward opening handle protruding inward in the width direction does not exceed 55mm. The innermost boundary of the maximum rotational envelope width is configured to maintain a physical safety gap of not less than 20mm between it and the preset passenger leg space boundary.

[0011] In one embodiment, the electronic inward-opening button has a backlit display structure, and the outer surface of the mechanical inward-opening handle has a chrome-plated layer.

[0012] In one embodiment, the mechanical inner-opening handle is in the shape of a ring or a straight handle, and the mechanical inner-opening handle and the electronic inner-opening button form a nested, parallel or semi-enclosed combination structure; The door armrest body is arranged in a straight, inclined or stepped shape relative to the horizontal reference plane, and the door armrest body is configured to connect with the surface of the dashboard interior parts or B-pillar interior parts.

[0013] In one embodiment, the door handle body is a one-piece molded structure, the mechanical inner opening handle has a downwardly extending sunken rotating arm, and the bottom end of the sunken rotating arm is formed with a cable connection mounting point. On the back of the door handle body, in the area below the cable connection mounting point, there is an assembly clearance cavity for the inner opening cable to enter. The opening size of the assembly clearance cavity in the height direction of the door handle body is not less than 50mm.

[0014] In one embodiment, the door handle body is a split-type molded structure, the door handle body includes a base body and a split cover plate, the dual-mode inward opening assembly is fixedly integrated on the split cover plate, the back of the mechanical inward opening handle is formed with a cable connection mounting point, and the split cover plate is configured to be detachably assembled and connected to the base body. The inner cable has a length allowance extending to the outside when the split cover plate is separated from the base body.

[0015] The present invention has the following beneficial effects: 1) Improve emergency safety: To address the problem of difficulty in identification caused by the separation of traditional electronic keys and mechanical handles, an integrated design is adopted to ensure that occupants can quickly locate and operate the device in an emergency, significantly shortening the response time for disaster avoidance.

[0016] 2) Optimize human-computer interaction experience: To address the issue of disjointed operation actions, the spatial alignment design of the inner and outer sides of the handrail enables a natural coordination between gripping the handrail and pressing the buttons, making the door opening and pushing logic intuitive and smooth.

[0017] 3) Enhanced protection against accidental touches: To address the potential risk of accidental activation of the buttons on the side of the armrest by passengers' knees, physical step differences and limiting structures are used to protect the electronic buttons, effectively eliminating the risk of accidental door opening under unnecessary conditions.

[0018] 4) Balancing space and functional layout: To address the challenge of interference between multiple modules within narrow armrests, a highly integrated functional layout is achieved through staggered spatial arrangement without encroaching on the lateral legroom of the cabin.

[0019] 5) Ensuring safety during dynamic movement: To address the issue of potential interference with the human body during the opening of the mechanical inner-opening handle, the rotation envelope space is precisely calibrated to ensure that the handle maintains a necessary safety clearance from the occupant throughout the entire stroke.

[0020] 6) Improve production and assembly efficiency: To address the pain point of difficult cable splicing in narrow cavities, a special assembly avoidance design and length redundancy significantly reduce the difficulty of mass production assembly and improve process reliability.

[0021] 7) Significantly reduce system cost and wiring complexity: By utilizing the specific geometric features of the mechanical inward-opening handle and the light source sharing logic of the electronic inward-opening button, regulatory identification requirements are met without the need for independent lighting elements and wiring harnesses, significantly reducing hardware cost and assembly complexity.

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0026] This invention proposes an integrated electromechanical dual-mode automotive door inward-opening armrest system, comprising: a door armrest body 1, a dual-mode inward-opening assembly 2, and a window regulator switch module 3. (See also...) Figure 1 .like Figure 15 The door armrest body 1 shown includes an armrest gripping area extending downwards from the top and a finger operation cavity formed on the side wall. A dual-mode inward opening assembly 2 is arranged within the finger operation cavity, which constitutes a characteristic area for finger operation of the dual-mode inward opening assembly 2. The dual-mode inward opening assembly 2 integrates an independently assembled electronic inward opening button 21 and a mechanical inward opening handle 22. A window regulator switch module 3 is arranged on the door armrest body 1. The dual-mode inward opening assembly 2 and the window regulator switch module 3 are arranged along the length of the door armrest body. In one embodiment, the electronic inward opening button is electrically connected to the vehicle door electronic control system to trigger an electronically controlled door opening signal. The mechanical inward opening handle is mechanically connected to the door lock mechanism via a cable to mechanically open the door when the electronic mode fails.

[0027] Furthermore, in the dual-mode inward-opening assembly 2, the mechanical inward-opening handle 22 and the electronic inward-opening button 21 are assembled independently and are two separate parts, and are not subject to mutual forces. The mechanical inward-opening handle 22 has a frame, and the touch surface of the electronic inward-opening button 21 is embedded in the frame. The frame protrudes from the surface of the electronic inward-opening button 21 to form a physical protective outer edge.

[0028] Furthermore, the mechanical inward-opening handle 22 has a support structure and a rebound stop on its back. The rebound stop is fixedly disposed behind the travel path of the mechanical inward-opening handle 22 as it moves inward toward the door armrest body 1, thereby limiting the maximum inward travel of the mechanical inward-opening handle 22. At the maximum inward travel, a safe gap is maintained between the frame of the mechanical inward-opening handle 22 and the electronic inward-opening button 21, i.e., they do not contact each other. In one embodiment, the support structure refers to the structure disposed on the back of the mechanical inward-opening handle, i.e., the side facing inward toward the door armrest body, used to provide back support when the handle is subjected to inward pushing force, and to prevent the handle from moving excessively inward or causing structural damage. In this application, the inner side of the door armrest body refers to the side away from the passenger and facing the door sheet metal.

[0029] Specifically, such as Figure 6As shown, the mechanical inward-opening handle 22 has a rebound stop, which limits the maximum inward movement of the handle and prevents the frame from moving further inward when accidentally pressed by the knee. Therefore, it can serve as a protective structure to prevent accidental activation of the electronic inward-opening button 21 in a knee-induced accidental activation simulation. The electronic inward-opening button 21 has a concave design and is positioned in an embedded manner. When the knee accidentally presses this area, the knee will only touch the frame of the mechanical inward-opening handle 22, and with the support structure and rebound stop behind it, the frame is prevented from moving further inward. Therefore, the electronic inward-opening button will not be accidentally triggered by the knee.

[0030] In this embodiment, the dual-mode inward-opening assembly is arranged in the upper half of the sidewall.

[0031] like Figure 2 As shown, the electronic inward-opening button 21 has a backlit display structure, providing a backlit effect. The outer surface of the mechanical inward-opening handle 22 has a chrome-plated layer and is located in a high-visibility area for passengers; both are highly recognizable and clearly visible.

[0032] The mechanical internal opening handle 22 is in the shape of a ring or a straight handle, and the mechanical internal opening handle 22 and the electronic internal opening button 21 form a nested, parallel, or semi-enclosed combination structure. It should be understood that the mechanical internal opening handle 22 and the electronic internal opening button 21 are integrated in the same position, and their shape is not limited, but they need to have high recognizability, and emergency and daily use functions are completely in the same area to completely eliminate safety risks. Figure 3 The integrated design achieves multi-dimensional regulatory compliance and cost reduction: on the one hand, the mechanically inward-opening handle 22 utilizes ring-shaped or straight-handle geometry to meet regulatory lighting exemption requirements; on the other hand, the mechanically inward-opening handle 22, by sharing the backlight of the electronic inward-opening button 21, visually forms an integrated lighting structure. Through these dual mechanisms, the mechanically inward-opening handle 22 eliminates the need for separate lighting elements and wiring harnesses, significantly reducing hardware costs while ensuring high recognizability. Several design schemes are listed in this article. Figure 2 and Figure 3 The patented scheme should include, but is not limited to, the scheme shown in the illustration.

[0033] According to design requirements, the dual-mode inward-opening assembly 2 and the window crank switch module 3 are located in the slightly forward area of ​​the handrail system. The placement of the electronic inward-opening button and all window crank switches and unlocking buttons must meet ergonomic requirements. Figure 4 As shown, using the X-coordinate position of the cross point on a 50% male human body model as the measurement reference, the geometric center of the electronic inner opening button 21 is no less than 300mm away from this measurement reference, and the distance from the foremost operating button of the window crank switch module 3 to this measurement reference is no more than 450mm. The cross point is also known as point H.

[0034] If the dual-mode inward opening assembly 2 and the window crank switch module 3 are relatively short in length, their internal structural spaces can be staggered. If they are relatively long, the internal structure of the window crank switch module 3 and the inward opening finger operation feature area of ​​the dual-mode inward opening assembly 2 can overlap to a certain extent, but the width of the overlapping area needs to be staggered.

[0035] like Figure 5 and Figure 15 As shown, in one embodiment, within the overlapping area, the internal structure of the window regulator switch module 3 is offset in the width direction towards the inside or outside of the door armrest body 1 to avoid the finger operating cavity, thereby ensuring that the maximum grip width of the door armrest body 1 in the overlapping area does not exceed 75mm. The maximum grip width in this application refers to the maximum distance along the width direction (Y direction) of the door armrest body in a cross-section perpendicular to the vehicle length direction (X direction) from the inner wall (the side adjacent to the passenger) to the outer wall (the side adjacent to the door sheet metal). This satisfies the ergonomic design requirements for the maximum armrest width, ensuring comfortable hand grip.

[0036] Furthermore, the width of the handrails should be set according to requirements at different locations within the handrail system. In the front and middle areas, it should not be too large, making gripping difficult, nor too small, resulting in insufficient space for internal mechanical structures. At the rear of the handrail, it should be as large as possible to ensure comfortable elbow support. The depth of the grip grooves should be defined; excessive depth will weaken the handrail and leave insufficient space for the lower cable installation, while insufficient depth will prevent fingers from gripping properly. The electronic buttons in the integrated dual-mode inward-opening assembly should be precisely positioned on the side of the handrail, perfectly corresponding to the height of the thumb to ensure comfort.

[0037] like Figure 7 As shown, the handrail gripping area is a groove structure extending downward from the top of the door handrail body. The top opening width of the groove structure is 25mm to 35mm, and the depth of the groove structure in the height direction of the door handrail body is 40mm to 60mm.

[0038] The sidewalls of the groove should be designed with a palm-grip-like curved surface to enhance grip comfort. Specifically, the inner sidewall of the groove structure is a concave curved surface that slopes outwards towards the vehicle's exterior, which is the side furthest from the vehicle's interior. The concave curved surface is configured as a contoured structure adapted to the gripping posture of the fingers, and the bottom area of ​​the groove structure forms a storage space for small items.

[0039] The geometric center of the electronic inward-opening button 21 is configured to correspond to the position of the thumb when the passenger naturally grips the handrail gripping area. This design allows the passenger's gripping operation to be synchronized with the thumb-activated electronic unlocking function, improving the convenience of unlocking and opening the door. On the side wall, the vertical height from the geometric center of the electronic inward-opening button 21 to the top surface of the door handrail body 1 does not exceed 50mm. (See [reference]). Figure 7 The height area of ​​the electronic inner opening button and the depth area of ​​the groove structure of the handrail grip area are spatially aligned on the inner and outer sides of the door handrail body, so as to configure a structure for synchronous and coordinated force application when the thumb presses and the other fingers grip.

[0040] The length of the dual-mode internal opening assembly 2 and the dimensions of its internal sub-components should be strictly defined, and the ergonomic dimensions of each internal sub-component should be defined according to the actual finger operating space requirements. For example... Figure 8 and 9 As shown, the electronic internal opening button 21 and the mechanical internal opening handle 22 are arranged inside the finger operating cavity. The electronic internal opening button has a length dimension d1 of not less than 30 mm, the finger operating cavity has a height dimension d4 of not less than 20 mm, the finger operating cavity has a width dimension d5 of not less than 18 mm, and the mechanical internal opening handle 22 has a length dimension d3 of not less than 10 mm at the operating end away from the rotating shaft.

[0041] exist Figure 8 In the design, there is a clearance between the mechanical inner-opening handle and the side wall of the finger operating cavity to allow finger access, and the minimum dimension d2 of the clearance in the length direction is not less than 25mm. Figure 9 In this design, d2 represents a clearance between the mechanical inward-opening handle and the electronic inward-opening button, allowing for finger access. The minimum length dimension of this clearance is also no less than 25mm.

[0042] like Figure 10 As shown, the mechanical inward-opening handle 22 is rotatably hinged to the inside of the door armrest body 1 via a mechanical inward-opening handle pivot 23, and the pivot is arranged near the side edge of the electronic inward-opening button 21. The limit rotation angle for the mechanical inward-opening handle to open inwards is configured in the range of 45° to 55°. During the movement from the initial closed position to the limit rotation angle, the maximum rotational envelope width of the mechanical inward-opening handle protruding inwards in the width direction does not exceed 55mm, that is, the maximum travel of the rotational envelope in the Y direction of the vehicle should not exceed 55mm. The innermost boundary of the maximum rotational envelope width is configured to maintain a physical safety gap of not less than 20mm between it and the preset passenger leg space boundary. This application is based on the thigh contour of a 95% male human body model. This design ensures that the rotational motion envelope of the mechanical handle avoids the passenger's legs and maintains a certain distance. Figure 10 The cross-sectional diagram in the figure ignores the avoidance of some shell boundary features due to the rotation envelope.

[0043] The mechanical inward-opening handle arm needs to meet the mechanical lock travel requirements and should be arranged inside the width of the handrail (considering the wall thickness on both sides and the fastening structure). At the same time, the feasibility of installing the inward-opening cable should be fully considered.

[0044] Specifically, when the door handrail body is a one-piece molded structure, the mechanical inward-opening cable needs to be installed from the back, and the inward-opening swing arm needs to be lowered and lengthened to ensure operability for cable installation at the bottom of the handrail groove. For example... Figure 11 As shown, the mechanical inward-opening handle has a downward-extending recessed rotating arm 24, with a cable connection mounting point formed at the bottom end of the recessed rotating arm. On the back of the door handle body, corresponding to the area below the cable connection mounting point, a mounting clearance cavity is formed for the inward-opening cable to enter. The opening size of the mounting clearance cavity in the height direction of the door handle body is not less than 50mm. Its material and structural rigidity must meet the stability requirements of the moving parts to avoid abnormal noise and jamming.

[0045] When the door handrail body is a split-type molded structure, the inner opening assembly can be integrated into the split cover plate. After the pull cable is pulled out and installed, the split cover plate can be reassembled onto the handrail system. For example... Figure 12 As shown, the door handle body includes a base body and a split cover plate, with a dual-mode inward opening assembly fixedly integrated onto the split cover plate. A cable connection mounting point is formed on the back of the mechanical inward opening handle, and the split cover plate is configured for detachable assembly with the base body. The cable has a length allowance extending to the outside when the split cover plate is separated from the base body.

[0046] This patented dual-mode inward-opening assembly design seamlessly integrates with the dashboard and B-pillar interior styling. The armrest system allows for the addition of other functional components, such as speakers, in other available spaces. The armrest is not entirely limited to a flat design; it can be angled or have its front section angled upwards. This design can also be applied to the overall cabin styling. See [link / reference]. Figure 13 and 14 In addition, the touch surface of the electronic internal button 21 is parallel to the outer surface of the side wall, or it can be set at an angle.

[0047] The present invention has the following beneficial effects: 1) Improve emergency safety: To address the problem of difficulty in identification caused by the separation of traditional electronic keys and mechanical handles, an integrated design is adopted to ensure that occupants can quickly locate and operate the device in an emergency, significantly shortening the response time for disaster avoidance.

[0048] 2) Optimize human-computer interaction experience: To address the issue of disjointed operation actions, the spatial alignment design of the inner and outer sides of the handrail enables a natural coordination between gripping the handrail and pressing the buttons, making the door opening and pushing logic intuitive and smooth.

[0049] 3) Enhanced protection against accidental touches: To address the potential risk of accidental activation of the buttons on the side of the armrest by passengers' knees, physical step differences and limiting structures are used to protect the electronic buttons, effectively eliminating the risk of accidental door opening under unnecessary conditions.

[0050] 4) Balancing space and functional layout: To address the challenge of interference between multiple modules within narrow armrests, a highly integrated functional layout is achieved through staggered spatial arrangement without encroaching on the lateral legroom of the cabin.

[0051] 5) Ensuring safety during dynamic movement: To address the issue of potential interference with the human body during the opening of the mechanical inner-opening handle, the rotation envelope space is precisely calibrated to ensure that the handle maintains a necessary safety clearance from the occupant throughout the entire stroke.

[0052] 6) Improve production and assembly efficiency: To address the pain point of difficult cable splicing in narrow cavities, a special assembly avoidance design and length redundancy significantly reduce the difficulty of mass production assembly and improve process reliability.

[0053] 7) Significantly reduce system cost and wiring complexity: By utilizing the specific geometric features of the mechanical inward-opening handle and the light source sharing logic of the electronic inward-opening button, regulatory identification requirements are met without the need for independent lighting elements and wiring harnesses, significantly reducing hardware cost and assembly complexity.

[0054] It should be understood that after the door handle body is installed inside the car, the length direction is the vehicle's X direction, that is, the vehicle's front-to-back direction; the width direction (also known as the lateral / thickness direction) is the vehicle's Y direction, that is, the vehicle's left-to-right direction; and the height direction (also known as the longitudinal direction) is the vehicle's Z direction, that is, the vehicle's up-to-down direction.

[0055] The embodiments described above are merely further illustrations of the present invention and are not intended to limit the present invention in any other way. The present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art can make various corresponding modifications and changes based on the present invention, but all such modifications and changes should fall within the protection scope of the present invention.
