[0050] The following first describes in detail the steering wheel 100 according to the embodiment of the utility model with reference to the accompanying drawings.

[0051] like Figures 1 to 10 As shown, the steering wheel 100 according to the embodiment of the present invention includes: a steering wheel body 10 , a movable frame 20 , an elastic member 30 and a control assembly 40 .

[0052] Specifically, the steering wheel body 10 is provided with a handle frame 11, the handle frame 11 is a ring with a notch, the movable frame 20 can be movably provided on the handle frame 11, the movable frame 20 can be extended and retracted on the handle frame 11, the elastic member 30 is provided on the handle frame 11, the elastic member 30 is provided with a accommodating space 321 adapted to the movable frame 20, the notch is located in the accommodating space 321, when the movable frame 20 extends out of the handle frame 11, the movable frame 20 fills the accommodating space 321, and the control component 40 is provided on the steering wheel body 10, and the control component 40 is configured to be able to control the movable frame 20 to retract to the handle frame 11.

[0053] In other words, if Figures 1 to 10As shown, the steering wheel 100 according to the embodiment of the utility model mainly includes a steering wheel body 10, a movable frame 20, an elastic member 30 and a control assembly 40, wherein the steering wheel body 10 is provided with a handle frame 11, the handle frame 11 is constructed as a circular ring structure with a notch, and the handle frame 11 can occupy approximately one-fifth to one-third of the entire circle. For example, the curvature of the handle frame 11 can be 210 degrees, and the first end and the second end of the handle frame 11 are located on both sides of the notch, and the movable frame 20 is constructed as an arc rod structure, and the arc edge of the movable frame 20 is concentric with the arc edge of the handle frame 11, and the movable frame 20 can be movably arranged at the first end or the second end of the handle frame 11 around the extension direction of its own arc edge, and the movable frame 20 can extend and retract from the handle frame 11.

[0054] like Figures 1 to 4 As shown, the elastic member 30 can be formed into an annular structure, the arc edge of the elastic member 30 is concentric with the arc edge of the grip frame 11, the elastic member 30 is sleeved on the grip frame 11, and the elastic member 30 is provided with a receiving space 321 at a position corresponding to the notch of the grip frame 11, so that the notch of the grip frame 11 is located in the receiving space 321, and the receiving space 321 is adapted to the movable frame 20. The control component 40 is provided on the steering wheel body 10, and the control component 40 is configured to be able to control the movable frame 20 to retract to the grip frame 11, so that the control component 40 can control the movable frame 20 to retract to the grip frame 11.

[0055] like Figures 1 to 4 As shown, when the movable skeleton 20 extends out of the handle skeleton 11, the movable skeleton 20 gradually fills the accommodating space 321. When the movable skeleton 20 is extended to the set position, the movable skeleton 20 fills the entire accommodating space 321. The movable skeleton 20 and the handle skeleton 11 can form a complete annular structure. At this time, the movable skeleton 20 supports the part of the elastic member 30 in the accommodating space 321, thereby ensuring the hardness of the steering wheel 100 at this place and ensuring the normal use of the driver; when the movable skeleton 20 is retracted to the handle skeleton 11, the accommodating space 321 is in an unfilled state. At this time, the steering wheel 100 has a smaller hardness at the position corresponding to the accommodating space 321 and has good elastic force, thereby playing a buffering and protective role when the driver's head hits this part.

[0056] The steering wheel 100 of the embodiment of the utility model is applied to a vehicle. When the steering wheel 100 is in the corrected state, the accommodating space 321 is located at the upper position of the steering wheel 100; when the vehicle is driving normally, the movable frame 20 fills the accommodating space 321, and the movable frame 20 supports the part of the elastic member 30 in the accommodating space 321, so that it is convenient for the driver to hold the steering wheel 100 in any direction, which is conducive to operation. Compared with a semicircular steering wheel, the steering wheel 100 of the utility model is more convenient, can effectively reduce the risk of operational errors, and improve driving safety.

[0057] like Figure 4 and Figure 7 As shown, when the vehicle collides or makes emergency braking, the control component 40 controls the movable frame 20 to retract to the handle frame 11, so that the movable frame 20 avoids the accommodating space 321. At this time, the steering wheel 100 has a smaller hardness at the position corresponding to the accommodating space 321 and has good elastic force. When the airbag is not opened or fails, it can play a buffering and protective role when the driver's head hits this part, thereby effectively reducing or avoiding injuries to the driver and effectively improving driving safety.

[0058] Therefore, according to the steering wheel 100 of the embodiment of the utility model, by providing a movable skeleton 20 that can be extended and retracted to the handle skeleton 11, when the movable skeleton 20 extends out of the handle skeleton 11, the hardness of the steering wheel 100 at the notch position of the handle skeleton 11 can be ensured, which is convenient for the driver to hold the steering wheel 100 at the notch position, can effectively reduce the risk of operational errors, and ensure driving safety; and through the provided control component 40, the movable skeleton 20 can be controlled to retract to the handle skeleton 11. When the movable skeleton 20 is retracted to the handle skeleton 11, the hardness of the steering wheel 100 at the position corresponding to the notch of the handle skeleton 11 is relatively small, and it has good elastic force, which can play a buffering and protective role on the driver's head, thereby effectively reducing or avoiding injuries to the driver and improving driving safety.

[0059] In some optional examples of the present invention, the control component 40 is also configured to control the movable skeleton 20 to extend out of the handle skeleton 11. For example, the control component 40 may include a motor and a gear. The motor can drive the gear to rotate. The wall surface of the movable skeleton 20 is provided with a plurality of teeth that mesh with the gears. By driving the gears to rotate, the movable skeleton 20 can be controlled to extend and retract from the handle skeleton 11.

[0060] According to an embodiment of the present invention, the steering wheel 100 includes two movable frames 20 , the first movable frame 20 is movably disposed at a first end of the handle frame 11 , and the second movable frame 20 is movably disposed at a second end of the handle frame 11 .

[0061] Specifically, a movable skeleton 20 is provided at the first end of the handle skeleton 11, and a movable skeleton 20 is also provided at the second end of the handle skeleton 11, and the two movable skeletons 20 are movable on the handle skeleton 11, so that the two movable skeletons 20 can extend from the handle skeleton 11 or retract to the two ends of the handle skeleton 11.

[0062] In this embodiment, the two movable skeletons 20 can be controlled to retract to the two ends of the handle skeleton 11 through the control component 40. Compared with setting up one movable skeleton 20, the retraction stroke of a single movable skeleton 20 is reduced, so that the movable skeleton 20 can be retracted to the handle skeleton 11 faster, effectively avoiding the collision between the position of the movable skeleton 20 and the driver's head, thereby ensuring driving safety.

[0063] In some specific embodiments of the present invention, a first guide channel 111 suitable for accommodating the movable frame 20 is disposed at the first end of the handle frame 11 , and the first end of the movable frame 20 is movably disposed in the first guide channel 111 .

[0064] That is to say, Figure 7 and Figure 8 As shown, the first end of the handle frame 11 is provided with a first guide channel 111 extending along the arc edge of the movable frame 20, and the first guide channel 111 is adapted to the movable frame 20, and the movable frame 20 can be accommodated through the first guide channel 111 when the movable frame 20 is retracted to the handle frame 11. During installation, the first end of the movable frame 20 can be movably inserted into the first guide channel 111, and the first guide channel 111 can play a guiding role when the movable frame 20 moves, and can ensure that the movable frame 20 has good stability when extending and retracting.

[0065] According to an embodiment of the present invention, a plug-in channel 112 is provided at the second end of the handle frame 11 , and the plug-in channel 112 is adapted to the second end of the movable frame 20 , and the second end of the movable frame 20 can be inserted into the plug-in channel 112 .

[0066] Specifically, Figure 6 and Figure 8 As shown, the second end of the handle frame 11 is provided with a plug-in channel 112 which is adapted to the second end of the movable frame 20. When the movable frame 20 extends out of the handle frame 11, the second end of the movable frame 20 extends into the plug-in channel 112. The plug-in channel 112 cooperates with the second end of the movable frame 20 to limit the second end of the movable frame 20, thereby ensuring the structural strength of the steering wheel 100.

[0067] In some specific embodiments of the present invention, the steering wheel 100 also includes: a first spring 50, the first spring 50 is arranged in the first guide channel 111, the first end of the first spring 50 is connected to the handle frame 11, and the second end of the first spring 50 is connected to the movable frame 20. When the movable frame 20 extends out of the handle frame 11, the first spring 50 is in a stretched state.

[0068] That is to say, Figure 3 and Figure 4 As shown, a first spring 50 is provided in the first guide channel 111, and the telescopic direction of the first spring 50 is the same as the extending direction of the first guide channel 111. The first end of the first spring 50 can be connected to the handle skeleton 11, and the second end of the first spring 50 can be connected to the first end of the movable skeleton 20.

[0069] like Figures 3 to 7 As shown, when the movable skeleton 20 is retracted in the first guide channel 111 of the handle skeleton 11, the first spring 50 can be in an unstretched state. When the movable skeleton 20 extends out of the first guide channel 111 of the handle skeleton 11, the first spring 50 is stretched. At this time, the first spring 50 applies a certain pulling force to the movable skeleton 20. The pulling force provided by the first spring 50 is conducive to the movable skeleton 20 to quickly retract and contract in the first guide channel 111 of the handle skeleton 11, and the contraction rate of the movable skeleton 20 can be guaranteed.

[0070] According to an embodiment of the present invention, the handle frame 11 is formed as an arc-shaped tube, a partition 113 is provided inside the arc-shaped tube, and the first end of the first spring 50 is connected to the partition 113 .

[0071] Specifically, Figures 6 to 8 As shown, the handle skeleton 11 is an arc-shaped tube, the inner wall surface of the arc-shaped tube defines a receiving channel, and the inner wall surface of the arc-shaped tube is fixedly connected with a partition 113, which can separate the receiving channel into a first guide channel 111 and a plug-in channel 112, and the partition 113 can provide a mounting position for the first spring 50, which is conducive to the installation and fixation of the first end of the first spring 50.

[0072] In some specific embodiments of the present utility model, a slot 21 is provided on the side wall of the movable skeleton 20, and the elastic member 30 is provided with a first avoidance groove, which is adapted to the position of the slot 21, and the control component 40 is provided with a retractable movable rod 41 so that the movable rod 41 can be extended into and out of the slot 21. When the movable skeleton 20 extends out of the handle skeleton 11, the movable rod 41 extends into the slot 21 to limit the position of the movable skeleton 20. When the movable rod 41 is out of the slot 21, the first spring 50 can pull the movable skeleton 20 to shrink into the first guide channel 111.

[0073] That is to say, Figures 6 to 10As shown, the inner peripheral side wall of the second end of the movable frame 20 is provided with a slot 21, the elastic member 30 is provided with a first avoidance slot, and the handle frame 11 is provided with a third avoidance slot 115. When the movable frame 20 extends out of the handle frame 11, the first avoidance slot and the third avoidance slot 115 correspond to the position of the slot 21. The control component 40 is provided with a telescopic movable rod 41. For example, the control component 40 can be an electric telescopic rod, and the telescopic part of the electric telescopic rod can be used as the movable rod 41. The control component 40 can also be other telescopic structures, which will not be described in detail in this embodiment.

[0074] When the movable skeleton 20 extends out of the handle skeleton 11, the control component 40 can control the movable rod 41 to pass through the first avoidance groove and extend into the slot 21. The position of the movable skeleton 20 can be fixed by the cooperation between the movable rod 41 and the slot 21. When it is necessary to control the movable skeleton 20 to retract, the control component 40 controls the movable rod 41 to disengage from the slot 21. At this time, the movable skeleton 20 can be retracted into the first guide channel 111 of the handle skeleton 11 under the pulling force of the first spring 50.

[0075] In this embodiment, the control component 40 does not need to apply a driving force to the movable frame 20 , and the movable frame 20 can complete the contraction under the pulling force of the first spring 50 , which has a simple structure and is easy to manufacture.

[0076] It should be noted that the control component 40 may also be other structures, which may be adaptively adjusted according to changes in other structures of the steering wheel 100, and will not be described in detail in this embodiment.

[0077] According to an embodiment of the present invention, the locking slot 21 extends along the movable direction of the movable frame 20 to form an arc-shaped slot.

[0078] like Fig.10 As shown, in this embodiment, the slot 21 is formed as an arc-shaped slot extending along the movable direction of the movable skeleton 20, which increases the error of the extended length of the movable skeleton 20 during assembly, is conducive to the alignment of the slot 21 and the movable rod 41, and can effectively improve the assembly efficiency.

[0079] In some specific embodiments of the utility model, the side wall of the movable rod 41 is provided with a plurality of teeth, and the plurality of teeth are distributed along the axial direction of the movable rod 41. The control component 40 also includes: a guide cylinder 42 and a driving member 43. The guide cylinder 42 is provided on the steering wheel body 10. The guide cylinder 42 is provided with a second guide channel 421 extending along its axis. The movable rod 41 is movably provided in the second guide channel 421. The driving member 43 is provided on the steering wheel body 10. The driving member 43 is provided with a rotatable gear shaft 431, and the gear shaft 431 is engaged with the teeth.

[0080] In other words, if Figure 7 and Fig. 9As shown, the control component 40 according to the embodiment of the utility model also includes a guide cylinder 42 and a driving member 43, wherein the guide cylinder 42 is fixed to the steering wheel body 10, the first end of the guide cylinder 42 faces the first avoidance groove, and the first end of the guide cylinder 42 is provided with a second guide channel 421 extending along its axial direction, the first end of the movable rod 41 is movably arranged in the second guide channel 421 along its axial direction, and the side wall of the movable rod 41 is provided with a plurality of teeth distributed along its axial direction; accordingly, in order to avoid the control component 40 from being too long, a connecting groove is opened on the side wall of the guide cylinder 42, and the position of the connecting groove corresponds to the position of the tooth portion, so that the guide cylinder 42 can expose the tooth portion.

[0081] The driving member 43 may be a motor, which is fixed to the steering wheel body 10. The output shaft of the motor may be formed as a gear shaft 431, or the output shaft of the motor may be sleeved with a gear, and the output shaft of the motor and the gear constitute the gear shaft 431, which may be meshed with the toothed portion at the position of the connecting groove.
