Description

Technical Field

[0001] The present application relates to the field of hidden door handles, and in particular to a hidden vehicle door handle with an ice-breaking structure. Background Art

[0002] Hidden door handles are ingeniously designed car door handles, whose main feature is that they are flush with the door surface or almost invisible when not in use, thus visually achieving a "hidden" effect of the door handle. This design not only provides a modern and technological appearance, but also reduces the drag coefficient and improves the airtightness of the cabin.

[0003] In the related art, the hidden door handle includes a base disposed in the door and a handle movably disposed in the base. When the handle is not in use, it is hidden in the base and flush with the door surface. A driving assembly for extending the handle is disposed in the base. When the door needs to be opened, the driving assembly drives the handle to move and extend from the door surface so that a person can grab it and open the door.

[0004] However, hidden door handles also face some obstacles during use. When the weather is cold, especially in the north, after the vehicle is left outdoors for a long time, especially at night, a layer of ice is easily frozen on the surface of the vehicle body, causing the hidden door handle to be unable to extend from the door surface, and then the door cannot be opened by the door handle. Utility Model Content

[0005] In order to solve the problem that the hidden door handle cannot be extended due to ice on the body surface, the present application provides a hidden door handle with an ice-breaking structure. The ice layer on the door handle can be broken by pressing the handle, and the door handle can be used normally after being reset.

[0006] The present application provides a hidden door handle with an ice-breaking structure, which adopts the following technical solution:

[0007] A hidden door handle with an ice-breaking structure comprises a handle and a base, wherein the base is arranged in the door, and the handle is movably arranged in the base. The handle comprises a connecting portion and a pressing portion, wherein the connecting portion is rotatably mounted on the base, and the pressing portion is used for a person to press the handle inward by hand. The base is located on a side of the pressing portion close to the interior of the vehicle and has a sinking space formed therein, wherein the pressing portion extends into the sinking space after being pressed. A swing arm is arranged in the base, and the swing arm is connected to an elastic member. The swing arm has at least one abutting end, and the abutting end continuously presses against the pressing portion under the elastic force of the elastic member and drives the handle to reset.

[0008] By adopting the above technical solution, the pressing part is pressed into the vehicle door to make the handle as a whole rotate around the rotating shaft of the connecting part, and the pressing part is extended into the sunken space, so that the ice layer at the handle can be broken and the ice-breaking effect can be achieved. After the ice-breaking is completed, the pressing part is released, the elastic part releases the elastic force and pushes the pressing part out of the sunken space through the abutting end, and the handle is reset. Thereafter, the handle can be extended from the vehicle door normally to cooperate with the human hand to grab and open the vehicle door.

[0009] Optionally, the swing arm includes a rotating arm and an abutment arm, the rotating arm is rotatably installed in the base and is located on one side of the sinking space, the abutment arm is fixed to the rotating arm and extends into the sinking space, and the elastic member is connected to the rotating arm.

[0010] By adopting the above technical solution, when a person presses the pressing part by hand and the handle rotates as a whole, the pressing part drives the abutment arm to move, and simultaneously drives the rotating arm to rotate, and then cooperates with the compression elastic part. After the pressing part is released, the rotating arm is reset under the elastic force of the elastic part to achieve the reset of the handle.

[0011] Optionally, the rotating arm and the abutting arm are combined to form an L-shaped structure.

[0012] By adopting the above technical solution, the abutment arm moves along an arc in the sinking space, and the rotating arm swings synchronously on one side of the sinking space. The two are closely matched with other components, and the structure is compact, which can effectively improve the space utilization efficiency.

[0013] Optionally, the swing arm also includes a limiting arm, which is fixed to the rotating arm. The base has a first limiting portion. When the pressing portion sinks into a preset position in the sinking space, the limiting arm presses against the first limiting portion to resist further sinking of the pressing portion.

[0014] By adopting the above technical solution, the first limiting portion limits the position of the limiting arm to resist further sinking of the pressing portion, thereby preventing the pressing portion from excessively extending into the sinking space and causing structural damage.

[0015] Optionally, the base is provided with a second limiting portion in the sinking space, and when the pressing portion is sunk to a preset position in the sinking space, the abutting arm abuts against the second limiting portion.

[0016] By adopting the above technical solution, the second limiting portion limits the position of the abutting arm, and cooperates with the first limiting portion and the limiting arm to further limit the downward pressure limit of the handle, thereby improving the stability of the overall structural operation.

[0017] Optionally, the rotating arm, the abutting arm and the limiting arm are an integrally formed structure.

[0018] By adopting the above technical solution, the processing accuracy and efficiency of the one-piece molding structure are higher, and the overall structural coordination is more stable.

[0019] Optionally, the elastic member includes a torsion spring, which is arranged at the rotating shaft of the rotating arm, and two ends of the torsion spring are respectively fixed to the base and the rotating arm.

[0020] By adopting the above technical solution, the torsion spring can form a torque between the rotating arm and the base, and the torsion spring always maintains a certain torque, so that the rotating arm always has the tendency to drive the abutting arm to press against the pressing part, ensuring the timeliness of the handle resetting and improving the stability of the overall mechanism operation.

[0021] Optionally, a gasket is provided on the side of the abutting arm for contacting the pressing portion.

[0022] By adopting the above technical solution, the gasket is used to reduce the wear between the pressing part and the abutting arm, and at the same time, the impact force between the two when pressed by external force is buffered, thereby improving the service life of the structure.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By pressing the pressing part into the door, the handle as a whole rotates around the rotating shaft of the connecting part, and the pressing part is extended into the sunken space, the ice layer at the handle can be broken to achieve the ice-breaking effect. After the ice-breaking is completed, the pressing part is released, the elastic part releases the elastic force and pushes the pressing part out of the sunken space through the abutting end, the handle is reset, and then the handle can be extended from the door normally to cooperate with the human hand to grab and open the door;

[0025] 2. The L-shaped structure formed by the combination of the rotating arm and the abutting arm, the abutting arm moves along the arc in the sinking space, and the rotating arm swings synchronously on one side of the sinking space. The two are closely matched with other components, the structure is compact, and the space utilization efficiency can be effectively improved;

[0026] 3. The torsion spring is used to form a torque between the rotating arm and the base, and the torsion spring always maintains a certain torque, so that the rotating arm always has the tendency to drive the abutting arm to press the pressing part, ensuring the timeliness of the handle reset and improving the stability of the overall mechanism operation.

DETAILED DESCRIPTION

[0034] The following is combined with Figure 1-6 This application is described in further detail.

[0035] The present application embodiment discloses a hidden door handle with an ice-breaking structure, referring to Figure 1 and Figure 2 , including a base 1 and a handle 2 movably arranged in the base 1, the base 1 is embedded in the inside of the car door, the handle 2 includes a connecting portion 21 and a pressing portion 22, the connecting portion 21 is rotatably installed in the inside of the base 1, and a sinking space 11 is formed in the base 1 at a side of the pressing portion 22 close to the inside of the car, and the pressing portion 22 is used for being pressed by a person's hand.

[0036] When in use, the pressing portion 22 is pressed toward the vehicle door to rotate the handle 2 as a whole around the rotating shaft of the connecting portion 21, so that the pressing portion 22 extends into the sinking space 11. When ice is frozen on the vehicle body surface, the pressing portion 22 is pressed by external force and forced to extend into the sinking space 11, so that the ice can be broken to achieve the ice-breaking effect.

[0037] Reference Figure 3 The base 1 is also provided with a swing arm 3, which is connected to an elastic member 4, and has at least one abutting end for abutting the pressing portion 22. The abutting end is always abutted against the pressing portion 22 under the elastic force of the elastic member 4 to reset the handle 2. When the pressing portion 22 is pressed into the sinking space 11, the pressing portion 22 drives the abutting end to move and compress the elastic member 4. After the ice breaking is completed, the pressing portion 22 is released, and the elastic member 4 releases the elastic force and pushes the pressing portion 22 out of the sinking space 11 through the abutting end to achieve the reset of the handle.

[0038] Further, refer to Figure 3 and Figure 4The swing arm 3 includes a rotating arm 31 and a contact arm 32. The rotating arm 31 is rotatably installed in the base 1 and is located on one side of the sinking space 11. The contact arm 32 is fixed to the rotating arm 31 and extends into the sinking space 11. The base 1 is provided with an avoidance opening corresponding to the moving trajectory of the contact arm 32 to cooperate with the movement of the contact arm 32.

[0039] Preferably, the rotating arm 31 and the abutting arm 32 are combined to form an L-shaped structure. The rotating shaft of the rotating arm 31 is arranged at one end away from the abutting arm 32, the abutting arm 32 moves along an arc in the sinking space 11, and the rotating arm 31 swings synchronously on one side of the sinking space 11. The two cooperate closely with other components, the structure is compact, and the space utilization efficiency can be effectively improved.

[0040] Preferably, a gasket 5 is provided on the side of the abutment arm 32 for contacting the pressing part 22. The gasket 5 is made of flexible material such as rubber and sponge, and is used to reduce the wear between the pressing part 22 and the abutment arm 32, while buffering the impact force between the two when external force is pressed, thereby improving the service life of the structure.

[0041] Further, refer to Figure 3 and Figure 5 The swing arm 3 also includes a limit arm 33, which is fixed to the end of the rotating arm 31 provided with a rotating shaft, and rotates with the rotating arm 31 around the rotating shaft. At the same time, the base 1 has a first limit portion 12, and when the pressing portion 22 sinks into the preset position of the sinking space 11, the limit arm 33 just abuts against the first limit portion 12. With the help of the limiting effect of the first limit portion 12 on the limit arm 33, the further sinking of the pressing portion 22 is resisted, so as to prevent the pressing portion 22 from excessively extending into the sinking space 11, resulting in structural damage.

[0042] Preferably, the rotating arm 31 , the abutting arm 32 and the limiting arm 33 are an integrally formed structure.

[0043] Further, refer to Figure 4 and Figure 6 The base 1 is provided with a second limiting portion 13 in the sinking space 11, and when the pressing portion 22 sinks into the preset position of the sinking space 11, the abutting arm 32 is attached to and abuts against the second limiting portion 13. The second limiting portion 13 is used to limit the position of the abutting arm 32, and the first limiting portion 12 cooperates with the limiting arm 33 to further limit the pressing limit of the handle 2, thereby improving the stability of the overall structure operation.

[0044] In this embodiment, a slope 14 is provided on the side wall of the sinking space 11 close to the interior of the vehicle, and when the pressing portion 22 sinks into a preset position of the sinking space 11, the pressing portion 22 adheres to and abuts against the slope 14 in the sinking space 11 to limit the sinking depth of the pressing portion 22.

[0045] Furthermore, the elastic member 4 includes a torsion spring 41, which is arranged at the rotating shaft of the rotating arm 31, and the two mounting ends of the torsion spring 41 are respectively fixed to the base 1 and the rotating arm 31, so as to form a torsion force between the rotating arm 31 and the base 1. Even when the handle 2 is in the normal position, the torsion spring 41 still forms a certain torsion force, so that the rotating arm 31 always has the tendency to drive the abutting arm 32 to abut against the pressing part 22, thereby ensuring the timeliness of the reset of the handle 2 and improving the stability of the operation of the overall mechanism.

[0046] The implementation principle of a hidden door handle with an ice-breaking structure disclosed in an embodiment of the present application is as follows:

[0047] When a layer of ice freezes on the surface of the vehicle body and the door handle cannot be used normally, the pressing part 22 is pressed inward from the outside of the door so that the pressing part 22 sinks into the sinking space 11 to break the ice at the handle 2. After the ice is broken, the pressing part 22 is released, and the abutting arm 32 pushes the pressing part 22 out of the sinking space 11 under the action of the torsion spring 41 to reset the handle 2.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
