All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative efforts are within the scope of the present invention. The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

A door handle covering device according to a broad embodiment of the present invention includes a handle cover and a driving device, and the driving device is drivingly coupled to the handle cover for driving the handle cover in a covering position Moving between the open position and the open position, the handle cover covers the door handle; in the open position, the handle cover exposes the door handle.

With the door handle covering device of the present invention, the handle can be covered with the handle cover, and the handle cover can be driven between the covered position and the open position. Thereby, the handle can be covered as needed, which is advantageous for reducing the wind noise when the vehicle is traveling at a high speed, and for reducing the length of time the handle is exposed to the outside, thereby facilitating the cleaning of the door handle.

It will be appreciated that the shape and configuration of the handle cover can be set according to the contour of the door around the door handle. Advantageously, the handle cover is better matched to the contour of the door around the door handle when in the covering position, on the same plane or smooth surface. The drive means can be of any suitable drive means, for example an electric drive (preferably driven by a stepper motor), an electromagnetic drive or a pneumatic drive or the like.

1 is a schematic perspective view of a door handle covering device in accordance with an embodiment of the present invention. Figure 2 is a side elevational view of the handle cover cover of Figure 1 with the handle cover in an initial position. Figure 3 is another side elevational view of the handle cover cover of Figure 1 with the handle cover already displaced. Figure 4 is a side elevational view of the handle cover covering device of Figure 1, wherein the handle cover has been displaced to the lowest position.

The illustrated door handle covering device comprises a handle cover 1 and a drive device 2. The drive device 2 is drivingly connected to the handle cover 1 for driving the handle cover to move between a covered position and an open position. In the covering position, the handle cover 1 covers the door handle (not shown), which is advantageous for keeping the door handle clean and reducing the wind noise when the vehicle is driving at a high speed. In the open position, the handle cover 1 exposes the door handle to facilitate operation of the door handle.

In the illustrated embodiment, the handle cover 1 is generally in the shape of a square plate. It can be understood that, in the present invention, the handle cover 1 is not limited to the illustrated shape. Advantageously, in the covering position, the handle cover 1 is well matched with the surrounding outer door structure contour (not shown), substantially in the same plane or on the same smooth curved surface, thereby being more favorable for reducing the wind during driving. noise. The material of the handle cover 1 is advantageously made of a high-strength plastic or aluminum alloy material.

In the embodiment shown in Fig. 1, the handle cover 1 is connected to the drive unit 2 via the connecting plate 3 and the connecting rod 4, and is thereby driven by the drive unit 2 to move between the covering position and the open position. It can be understood that the manner in which the handle cover 1 and the driving device 2 are connected is not limited to the illustrated structure and manner, and It is possible to use any suitable connection method. In an unillustrated embodiment, the handle cover 1 is rotationally driven by the drive means via a gear-gear connection. In another embodiment, not shown, the handle cover 1 is driven in translation by the drive unit via a rack-and-gear connection. In yet another embodiment, the handle cover 1 is driven by the drive means via a cam structure.

In the embodiment shown in Figure 1, the drive unit 2 comprises a slider 5a, a guiding block 5b and a connecting block 7. The slider 5a is moved between the covering position and the open position under the action of the first permanent magnet 6 provided therein and under the action of the spring 9. The specific mode of motion is described in detail below.

The connecting block 7 is fixedly connected to the slider 5a. The connecting block 7 and the slider 5a can be regarded as one member in motion. Even the connecting block 7 and the slider 5a may be one member or integrally formed. One end of the connecting rod 4 (the left end in Fig. 1) is fixedly connected to the handle cover 1 via the connecting plate 3, and the other end (the right end in Fig. 1) is fixedly connected to the connecting block 7. The manner of connection between the slider 5a and the handle cover is not limited to this configuration, but any suitable structure may be employed.

As shown, the slider 5a is generally rectangular in shape with a circular chamfer at each corner. Referring to Fig. 1, the lower bottom side of the slider 5a is in contact with the upper side of the guide block 5b, and is supported above the upper side of the guide block 5b, and is slidable left and right along the upper side of the guide block 5b. The guiding block 5b is fixed to the bottom plate 16. In addition to providing an upward support for the slider 5a, the slider 5a is also provided with a leftward retention force, as described in detail below.

In addition, a guide plate 8 (first guide) is also provided to guide the left and right sliding of the slider 5a (movement in the horizontal direction). Specifically, the tip end of the slider 7 is in contact with the guide plate 8 and is movable in parallel along the guide plate 8. Advantageously, the top end of the slider 7 is T-shaped, embedded in the T-shaped groove of the guide plate 8, and slides left and right under the guidance of the T-shaped groove. Advantageously, the guide plate 8 is provided with a fixed stop (not shown) near one end (left end) of the handle cover 1 for limiting the maximum sliding extent of the slider 7 along the guide plate 8. The maximum sliding range of the slider 7 to the right along the guide plate 8 is achieved by the slider 5a abutting against the electromagnetic coil housing 12.

The electromagnetic coil housing 12 is fixedly coupled to the guide plate 8. The solenoid housing 12 and the guide plate 8 can be seen as one member in motion. Even, the electromagnetic coil housing 12 and the guide plate 8 may be one member or integrally formed. An electromagnet 13 is fixedly disposed in the electromagnetic coil case 12. The electromagnet 13 can be energized in different directions to present different magnetic polarities.

When the electromagnet 13 is energized by the first current direction, the electromagnet 13 and the first permanent magnet 6 The first permanent magnets 6 are moved to the right, so that the slider 5a and the connecting block 7 are moved to the right, and finally the handle cover 1 is moved to the right. When moving to the right, the movement of the connecting block 7 is guided by the guide plate 8 without deviating from the direction of movement. It should be noted that when the slider 5a is moved to the right to the extreme position (for example, the right vertical side of the slider 5a abuts the left vertical side of the electromagnetic coil housing 12), the bottom surface of the slider 5a is over-guided. The top surface of the block 5b is thus free to move up and down.

When the electromagnet 13 is supplied with a current opposite to the first current direction, the electromagnet 13 and the first permanent magnet 6 repel each other, so that the first permanent magnet 6 moves to the left, thereby driving the slider 5a and the connecting block. 7 moves to the left, eventually moving the handle cover 1 to the left. When moving to the left, the movement of the connecting block 7 is guided by the guide plate 8 so as not to deviate from the direction of movement. In addition, the maximum range of movement to the left is limited by a limit block (not shown).

The electromagnetic coil housing 12 is disposed within the guide housing 14 (second guide) and is vertically movable up and down along the guide housing 14. That is, the guide plate 8 can be vertically slid along the guide housing 14 and further drive the slider 5a, the first permanent magnet 6, the connecting block 7, the connecting rod 4, the connecting plate 3 and the handle cover 1 Move up and down vertically. It can be understood that the electromagnetic coil housing 12 can also be disposed to be sleeved outside the guide housing 14 or to cooperate with the guide housing 14 in other configurations as long as the guide housing 14 can guide the vertical alignment of the electromagnetic coil housing 12. Just move in the direction.

In order to avoid the entry of dust, a cover plate 11 is provided at the top of the guide housing 14.

The driving force for the vertical up and down movement is provided by the electromagnet 13 and the second permanent magnet 15 fixedly disposed with respect to the guide housing 14.

When the electromagnet 13 is supplied with a current in the first current direction, the electromagnet 13 and the second permanent magnet 15 attract each other. Since the second permanent magnet 15 is fixed relative to the guide housing 14 (or the bottom plate 16), the electromagnet 13 is attracted by the second permanent magnet 15 to move downward, thereby driving the electromagnetic coil housing 12 and the guide plate 8 to move downward. The guide plate 8 in turn drives the slider 5a and the connecting block 7 to move downward. Finally, the handle cover 1 is moved downward until the bottom surface of the slider 5a contacts the bottom plate 16. It can be understood that since the electromagnet 13 and the first permanent magnet 6 are attracted to each other as described above, the slider 5a has moved to the right to the extreme position, so that the slider 5a can freely slide up and down. Advantageously, the electromagnetic coil housing 12 and the slider 5a are provided with interlocking limiting structures. When the slider 5a is moved to the rightmost position, the limiting structures cooperate with each other, thereby making the electromagnetic coil housing 12 and the slider 5a are better integrally moved in the height direction. The limiting structure includes, for example, a tapered column disposed on the slider 5a, and is disposed on the electromagnetic coil Corresponding tapered holes in the housing 12.

When the electromagnet 13 is supplied with a current opposite to the direction of the first current, the electromagnet 13 and the second permanent magnet 15 repel each other, so that the electromagnet 13 moves upward, thereby driving the electromagnetic coil housing 12 and the guide plate 8. Moving upwards, the guide plate 8 in turn drives the slider 5a and the connecting block 7 to move upwards, and finally the handle cover 1 is moved upward. When the slider 5a is moved upward to the critical height, the bottom surface of the slider 5a passes over the top surface of the guide block 5b, and the guide block 5b no longer provides the leftward holding force to the slider 5. At this time, the mutual repulsive force of the electromagnet 13 and the first permanent magnet 6 causes the slider 5a to move to the left until the stopper blocks the connecting block 7 from moving further to the left. At this time, the position of the handle cover may be set as the cover position of the handle cover, or may be set as the open position of the handle cover.

The spring 9 is arranged between the connecting block 7 and the end of the guide plate 8 adjacent to the handle cover 1, always exerting a leftward elastic force on the connecting block 9. In one embodiment, the position of the connection block 7 at the leftmost position corresponds to the open position of the handle cover 1. Thus, when the electromagnet 13 is not energized, the connecting block 7 is only held in the open position by the action of the spring 9, thereby facilitating the operator to operate the handle cover. If it is necessary to cover the handle (for example, while the vehicle is running), the electromagnet 13 is energized to move the handle cover from the open position to the cover position, thereby reducing wind noise when the vehicle is running.

In another embodiment, the position of the connection block 7 at the leftmost position corresponds to the position of the hood of the handle cover 1. Thus, when the electromagnet 13 is not energized, the connecting block 7 is only held by the spring 9 in the covering position, so that the handle cover always covers the handle, so that the whole vehicle has a smooth and more complete appearance, and at the same time has a better driving Small wind noise. If it is necessary to operate the handle and the handle cover needs to be in the open position, the electromagnet 13 is energized to move the handle cover from the cover position to the open position. After the operation of the handle is completed, the electromagnet 13 is stopped from being energized, and the handle cover is restored to the cover position. Such an embodiment is particularly suitable for fully automated vehicles, especially self-driving vehicles or self-propelled vehicles.

Advantageously, a compression spring (not shown) is provided between the bottom of the electromagnetic coil housing 12 and the bottom plate 16, and an upward elastic force is always applied to the electromagnetic coil housing 12. It can be understood that the pressure-receiving spring can also be replaced by a tension spring, for example, by a tension spring disposed between the top of the electromagnetic coil housing 12 and the top of the guide housing 14, which is always electromagnetically The coil housing 12 exerts an upward elastic force. The pressure spring can be replaced with other elastomers as needed.

When the door handle needs to be operated, the control system integrated on the car control panel issues an instruction, Thereby, the electromagnetic coils of the electromagnets 13 built in the electromagnetic coil case 12 are supplied with power, and the opposite faces of the electromagnets 13 and the second permanent magnets 15 are opposite in polarity, and the electromagnets 13 and the first permanent magnets 6 are attracted to each other. Then, the first permanent magnet 6 drives the slider 5a, thereby driving the slider 7 to slide along the guide plate 8. At this time, the slider 5a drives the connecting rod 4, thereby driving the connecting plate 3 to move together with the handle cover 1. The slider 5a and the guiding block 5b slide relative to each other in the horizontal direction until their bottom rounded corners are staggered from each other. At this time, due to the attraction between the electromagnet 13 and the second permanent magnet 15, the electromagnet 13 drives the electromagnetic coil housing. The body 12, the guide plate 8, and the associated components connected to the guide plate 8 are moved downward together until the electromagnet 13 is in contact with the second permanent magnet 15, and a schematic view of the driving device is shown in FIG. The handle cover 1 is moved downward together, and the handle is exposed for operation by the vehicle user.

When it is not necessary to operate the door handle, the control system issues a command to supply power to the electromagnetic coil of the electromagnet 13 in reverse, and a repulsive force is generated between the electromagnet 13 and the second permanent magnet 15. The electromagnet 13 drives the related components to move up together. When the step of the slider 5a moves to the upper side of the guiding block 5b, the guiding block 5b no longer restricts the horizontal movement of the slider 5a, so that the mutual repulsive force of the electromagnet 13 and the first permanent magnet 6 and the pulling force of the spring 9 cause the slider 5a Slide horizontally in the direction of the handle cover until the slider 7 comes into contact with the stop block and the entire unit is reset.

In the prior art, the door handle of the automobile is usually exposed to the outside, and the door panel at the handle is uneven. On the one hand, the design is bare, it is easy to get dust, and it is not beautiful; on the other hand, it will increase the wind noise when the car is driving at high speed and reduce the comfort of the car.

The invention provides a door handle covering device, which realizes covering the handle, so that the handle is not easily contaminated with dust without affecting the function of the handle, the handle area is more neat and beautiful, and the wind noise during high-speed driving of the automobile can be reduced.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not limited thereto. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or equivalently replace some of the technical features.
