Description
Technical Field
[0001] This invention belongs to the field of automotive door handle technology and relates to a swing-out concealed door handle. Background Technology
[0002] Concealed car door handles are widely used because they are flush with the outer surface of the door, which better suits the streamlined design of the car body and enhances its aesthetics. However, when the ambient temperature drops below freezing, residual moisture in the gap between the handle and the door may condense into ice, freezing the handle and door together and affecting usability.
[0003] To address this, a Chinese patent discloses an ice-breaking and resetting device for a hidden car door handle [authorization announcement number CN214273272U], comprising a handle body, a buffer pad, a spring cover, a compression spring, a housing, and a base bracket. When the user presses the ice-breaking component area of the handle body, the buffer pad causes the spring cover to compress the compression spring, pushing the handle body inward toward the car door. At this time, the ice breaks due to the inward displacement of the handle body. When the user releases their hand, the compression spring resets due to the removal of external force, thereby generating elastic force on the housing and spring cover at both ends. Since the housing is fixed in the mounting hole, the compression spring pushes the spring cover and buffer pad outward toward the outside of the handle body, thereby causing the handle body to spring up until its outer surface is flush with the outer surface of the car door, after which the user can open the car door normally.
[0004] Because the handle body has a swing component inside, pressing the handle body inward will be blocked by the swing component, resulting in a very small inward movement distance of the handle body, which cannot effectively break ice; the force that the user presses on the handle body cannot be precisely controlled, and when the force is too large, it may damage the swing component located inside the handle, increasing maintenance costs. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a swing-out concealed door handle with good ice-breaking effect.
[0006] The objective of this invention can be achieved through the following technical solutions:
[0007] The swing-out concealed door handle includes a handle that is rotated inside the door and an actuator for driving the handle to swing outward. The inner side of the handle is provided with an ice-breaking component driven by the actuator. When breaking ice, the ice-breaking component acts on the inner side of the swing-out end of the handle.
[0008] During ice breaking, the ice-breaking component acts on the inside of the swing-out end, pushing it outward from the inside. This provides a large outward movement space, making ice breaking easier and more effective. After ice breaking, the ice-breaking component disengages from the actuator, preventing it from entering the door handle cavity. Then, under the action of the actuator, the swing-out end swings outward again.
[0009] In the above-mentioned swing-out concealed door handle, the inner side of the handle is provided with an inwardly extending action part, and the actuator is located on the side of the action part away from the swing-out end. When breaking ice, the actuator acts on the ice-breaking component, and after breaking ice, the actuator acts on the action part.
[0010] The actuator is a linear drive component, and its direction of action extends along the length of the handle when it is in the locked state. By extending or retracting the moving end of the actuator, it pushes the ice-breaking component or the action part, thereby driving the ice-breaking component to break the ice, or driving the handle to swing outward.
[0011] In the aforementioned swing-out concealed door handle, the ice-breaking assembly includes a rocker arm rotatably disposed inside the door. The rotation centerline of the rocker arm is parallel to the rotation centerline of the handle. One end of the rocker arm extends to the side of the actuating part near the actuator. A pressing structure is provided between the rocker arm and the actuator to swing the end of the rocker arm away from the actuator outward when the actuator is activated. The other end of the rocker arm extends to the inside of the handle swing-out end. A push-out structure is provided at the other end of the rocker arm to push the handle outward when the rocker arm swings.
[0012] Because one end of the joystick extends to the side of the actuator near the actuating part, the actuator acts on the joystick first, and then on the actuating part, thus achieving the function of breaking ice first and then swinging the handle. The distance from the point where the joystick acts on the handle to the center of the handle's rotation is greater than the distance from the point where the actuator acts on the handle to the center of the handle's rotation, increasing the lever arm and making it easier to break ice.
[0013] In the aforementioned swing-out concealed door handle, the extrusion structure includes an action surface located at the end of the rocker arm near the actuator. The action surface extends obliquely from the inside to the outside along the action direction of the actuator, and the actuator acts on the action surface when breaking ice.
[0014] The action surface extends from the inside to the outside along the action direction of the actuator (i.e. the direction of extension of the actuator's movable end). When the movable end of the actuator extends, it presses against the action surface, causing the action surface to move inward under force, thereby causing the end of the rocker arm away from the actuator to swing outward.
[0015] In the aforementioned swing-out concealed door handle, the push-out structure includes a push rod that is slidably disposed inside the door. When breaking ice, the outer side of the rocker arm away from the actuator abuts against the inner end of the push rod, and the outer end of the push rod abuts against the inner side of the swing-out end of the handle.
[0016] To reduce friction between the joystick and the push rod, a circular protrusion is provided on the joystick. When the joystick swings, the circular protrusion makes point contact with the inner end of the push rod, reducing the contact area.
[0017] In the above-mentioned swing-out concealed door handle, the door is provided with a guide hole on the inner side of the handle swing-out end, the push rod is slidably disposed in the guide hole, the end of the guide hole near the handle is provided with an annular stop, the inner end of the push rod is provided with a limiting shoulder, a spring sleeved on the push rod is provided between the annular stop and the limiting shoulder, and a de-extrusion structure is provided between the rocker and the actuator to disengage the extrusion structure after ice breaking.
[0018] The rocker arm is located in the space inside the guide hole. The spring is limited between the annular stop and the limiting shoulder. When breaking ice, the outer end of the push rod extends into the handle cavity of the door. At this time, the spring is compressed by the limiting shoulder. After breaking ice, the expulsion structure makes the rocker arm disengage from the actuator, the spring returns to its original position, and the outer end of the push rod retracts from the handle cavity to prevent the push rod from touching the hand when holding the handle.
[0019] In the aforementioned swing-out concealed door handle, the de-squeezing structure includes a first protrusion located at the end of the rocker arm near the actuator and a second protrusion located at the movable end of the actuator. The working surface is located on the first protrusion. When breaking ice, the second protrusion abuts against the working surface of the first protrusion. After breaking ice, the second protrusion passes over the first protrusion to disengage the de-squeezing structure from its working state.
[0020] After the second protrusion passes the first protrusion, the actuator no longer applies force to the rocker arm.
[0021] In the above-mentioned swing-out concealed door handle, the rocker arm is located on the upper / lower side of the action part, the movable end of the actuator is provided with a slider, and the second protrusion is provided on the slider.
[0022] The rocker arm is located on the upper / lower side of the action part, reducing the space occupied in the thickness of the door. The slider is located on the side of the action part closer to the actuator and on the outside of the rocker arm closer to the actuator. In the initial stage of the second protrusion pressing the first protrusion, the slider has not yet acted on the action part. The slider only begins to act on the action part after the ice is broken.
[0023] In the aforementioned swing-out concealed door handle, the rocker arm is rotatably mounted inside the door via a first pivot, and the distance from the point where the actuator acts on the rocker arm to the first pivot is greater than or equal to the distance from the point where the rocker arm acts on the handle to the first pivot.
[0024] Forming a force-saving lever or an equal-arm lever makes it easier to break the ice.
[0025] In the aforementioned swing-out concealed door handle, the handle is rotatably mounted inside the door via a second pivot, which is located at the end of the handle away from the swing-out end.
[0026] A cable seat is installed on the inside of the handle. When the handle is swung outward, the cable seat is not affected by the actuating part. When the handle is fully swung outward, the handle is pulled outward around the second pivot. The handle causes the actuating part to swing, and the actuating part will drive the cable seat to rotate, thereby opening the door lock.
[0027] Compared with existing technologies, this swing-out concealed door handle has the following advantages:
[0028] During ice breaking, the ice breaking component acts on the inside of the swing-out end, pushing the swing-out end outward from the inside. The large outward movement space makes it easier to break the ice and the ice breaking effect is better. The distance from the point on the handle where the rocker arm acts to the center of rotation of the handle is greater than the distance from the point on the handle where the actuator acts to the center of rotation of the handle, which increases the lever arm and makes it easier to break the ice. After ice breaking is completed, the top rod retracts under the action of the spring and the de-extrusion structure, preventing the top rod from touching the hand when holding the handle and improving the comfort of operation.

Detailed Implementation
[0036] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0037] like Figure 1The swing-out concealed door handle shown includes a handle 1 rotatably housed within the handle cavity of the car door and an actuator 2 for driving the handle 1 to swing outward. The handle 1 is rotatably mounted on the car door via a second pivot 14, which is positioned near the end of the handle 1 furthest from the swing-out end. An inwardly extending actuating part 3 is provided on the inner side of the handle 1, located close to the second pivot 14. The actuator 2 is located on the side of the actuating part 3 furthest from the swing-out end. During ice breaking, the actuator 2 acts on the ice-breaking assembly; after ice breaking, the actuator 2 acts on the actuating part 3. The actuator 2 is a linear drive component, its direction of action extending along the length of the handle 1 in the locked state. The extension and retraction of the movable end of the actuator 2 pushes the actuating part 3, causing the swing-out end of the handle 1 to swing outward around the second pivot 14.
[0038] To enable the handle 1 to break the ice between the handle 1 and the door before swinging out, an ice-breaking component driven by the actuator 2 is installed on the inner side of the handle 1. During ice breaking, the ice-breaking component acts on the inner side of the swing-out end of the handle 1, pushing the swing-out end outward from the inside. The large outward movement space makes it easier to break the ice and results in a better ice-breaking effect. After ice breaking, the ice-breaking component disengages from the actuator 2 to prevent it from entering the handle cavity of the door. Then, under the action of the actuator 2, the swing-out end swings outward.
[0039] like Figure 1 As shown, the ice-breaking assembly includes a rocker arm 4 rotatably mounted inside the car door. The rocker arm 4 is rotatably mounted inside the car door via a first rotating shaft 13. The first rotating shaft 13 is parallel to the second rotating shaft 14. In this embodiment, the distance from the point where the actuator 2 acts on the rocker arm 4 to the first rotating shaft 13 is equal to the distance from the point where the rocker arm 4 acts on the handle 1 to the first rotating shaft 13.
[0040] like Figure 1-4 As shown, one end of the rocker arm 4 extends to the side of the actuating part 3 near the actuator 2. A squeezing structure is provided between the rocker arm 4 and the actuator 2 to cause the end of the rocker arm 4 away from the actuator 2 to swing outwards when the actuator 2 is activated. The other end of the rocker arm 4 extends to the inner side of the swing-out end of the handle 1. A pushing structure is provided at the other end of the rocker arm 4 to push the handle 1 outwards when the rocker arm 4 swings. When the actuator 2 is activated, it first acts on the rocker arm 4, and then on the actuating part 3, achieving the function of breaking ice first and then swinging out the handle 1. The distance from the point where the rocker arm 4 acts on the handle 1 to the center of rotation of the handle 1 is greater than the distance from the point where the actuator 2 acts on the handle 1 to the center of rotation of the handle 1, increasing the lever arm and making ice breaking easier.
[0041] like Figure 2-4As shown, the extrusion structure includes an action surface 5 located at the end of the rocker 4 near the actuator 2. The action surface 5 extends obliquely from the inside to the outside along the action direction of the actuator 2. When breaking ice, the actuator 2 acts on the action surface 5. The action surface 5 extends obliquely from the inside to the outside along the action direction of the actuator 2 (i.e., the extension direction of the movable end of the actuator 2). When the movable end of the actuator 2 extends, it extrudes the action surface 5, causing the action surface 5 to move inward under force, thereby causing the end of the rocker 4 away from the actuator 2 to swing outward.
[0042] like Figure 5 As shown, the ejector structure includes a push rod 6 slidably disposed inside the door. When breaking ice, the outer side of the rocker arm 4 away from the actuator 2 abuts against the inner end of the push rod 6, and the outer end of the push rod 6 abuts against the inner side of the swing-out end of the handle 1. To reduce friction between the rocker arm 4 and the push rod 6, as shown... Figure 5 As shown, a circular protrusion is provided on the rocker arm 4. When the rocker arm 4 swings, the circular protrusion makes point contact with the inner end of the top rod 6, reducing the contact area.
[0043] like Figure 5 As shown, a guide hole is provided on the inner side of the handle 1 at the door's swing-out end. The push rod 6 is slidably disposed in the guide hole. An annular retaining edge 7 is provided at the end of the guide hole near the handle 1. A limiting shoulder 8 is provided at the inner end of the push rod 6. A spring 9 is sleeved on the push rod 6 between the annular retaining edge 7 and the limiting shoulder 8. A de-extrusion structure is provided between the rocker arm 4 and the actuator 2 to disengage the compression structure after ice breaking. The rocker arm 4 is located in the space within the inner end of the guide hole. The spring 9 is limited between the annular retaining edge 7 and the limiting shoulder 8. When ice breaking, the outer end of the push rod 6 extends into the handle cavity of the door. At this time, the spring 9 is compressed by the limiting shoulder 8. After ice breaking, the de-extrusion structure disengages the rocker arm 4 from the actuator 2, the spring 9 returns to its original position, and the outer end of the push rod 6 retracts from the handle cavity, preventing the push rod 6 from touching the hand when gripping the handle 1.
[0044] like Figure 6 As shown, the de-extrusion structure includes a first protrusion 10 located at the end of the rocker arm 4 near the actuator 2 and a second protrusion 11 located at the movable end of the actuator 2. The working surface 5 is located on the first protrusion 10. During ice breaking, the second protrusion 11 abuts against the working surface 5 of the first protrusion 10. After ice breaking, the second protrusion 11 passes over the first protrusion 10, causing the extrusion structure to disengage. After the second protrusion 11 passes over the first protrusion 10, the actuator 2 no longer applies force to the rocker arm 4.
[0045] In this embodiment, the movable end of the actuator 2 is provided with a slider 12, and the second protrusion 11 is provided on the slider 12. The rocker arm 4 is located on the upper / lower side of the action part 3, which reduces the space occupied in terms of the door thickness. The slider 12 is located on the side of the action part 3 near the actuator 2, and is located on the outer side of the rocker arm 4 near the actuator 2. In the initial stage when the second protrusion 11 presses the first protrusion 10, the slider 12 has not yet acted on the action part 3. The slider 12 only begins to act on the action part 3 after the ice is broken.
[0046] When ice breaking is required, such as Figure 2 As shown, actuator 2 pushes slider 12, slider 12 pushes action surface 5, causing action surface 5 to move inward, thereby causing rocker arm 4 to rotate around the first rotating axis 13. During the rotation, rocker arm 4 pushes push rod 6, push rod 6 pushes handle 1, thus breaking the ice. After the handle 1 breaks the ice, as shown... Figure 3 As shown, actuator 2 continues to push slider 12, slider 12 begins to disengage from rocker 4, slider 12 pushes action part 3 to move, causing the swing end of handle 1 to rotate outward.
[0047] like Figure 4 As shown, a cable seat 15 is provided on the inner side of the handle 1. During the process of the handle 1 swinging outward, the cable seat 15 is not affected by the action part 3. When the swing end of the handle 1 is fully swinging outward, the handle 1 is pulled outward around the second rotating shaft 14. The handle 1 drives the action part 3 to swing, and the action part 3 will drive the cable seat 15 to rotate, thereby opening the door lock.
[0048] The specific embodiments described herein are merely illustrative of the spirit of the invention.
