[0057] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this disclosure as detailed in the appended claims.

[0058] In this disclosure, unless otherwise stated, directional terms such as “inner” and “outer” refer to the inner and outer parts of a specific structural outline; terms such as “first” and “second” are used only to distinguish one element from another and do not have any sequential or important meaning.

[0059] Reference Figure 1 As shown, this disclosure provides a method for adjusting the position of a steering wheel, including:

[0060] S11, obtain the first distance between the steering wheel 10 and the driver.

[0061] The initial distance between the steering wheel 10 and the driver can be acquired either in real time or when the airbag deployment signal is triggered; this disclosure does not limit this. Furthermore, this disclosure does not limit the method of acquisition; it can be acquired through sensors or the vehicle's built-in monitoring system.

[0062] S12, determine the first difference between the first distance and the target distance, where the target distance is the pre-calibrated airbag deployment distance between the steering wheel 10 and the driver.

[0063] The target distance is the pre-calibrated airbag deployment distance between the steering wheel 10 and the driver. At this target distance, the airbag will deploy neither too close to nor too far from the driver, and the airbag can effectively protect the driver after it deploys from the steering wheel 10.

[0064] S13, when the airbag deployment signal is triggered, the steering wheel 10 is extended or retracted by the steering wheel position adjustment device according to the first difference.

[0065] In the above technical solution, when the airbag deployment signal is triggered, the extension and retraction of the steering wheel 10 are adjusted by the steering wheel position adjustment device, thereby adjusting the distance between the steering wheel 10 and the driver to provide the driver with appropriate buffer space, reduce the impact on the driver when the airbag in the steering wheel 10 deploys, effectively protect the driver, and improve the safety factor.

[0066] Optionally, refer to Figure 2 As shown, obtaining the first distance between the steering wheel 10 and the driver includes:

[0067] S111, Obtain the driver's head position;

[0068] S112, Obtain the spatial position of the steering wheel 10 in the vehicle's cockpit;

[0069] S113, determine the first distance based on the head position and spatial position.

[0070] In this embodiment, firstly, the driver's head position can be obtained either by installing a position measuring device inside the vehicle or by using a monitoring system built into the vehicle; this disclosure does not limit the method. Secondly, the spatial position of the steering wheel 10 in the vehicle's cockpit can also be obtained by installing a position measuring device inside the vehicle; for example, this position measuring device can be configured as a position sensor, and this disclosure does not limit the method. Furthermore, the obtained driver's head position information and the spatial position of the steering wheel 10 in the vehicle's cockpit can be fed back to the in-vehicle controller to determine a first distance; however, this disclosure does not limit the specific method for determining the first distance.

[0071] In one embodiment, the position adjustment device includes an adjustment lever 1 connected to the steering wheel 10, and a position measuring device for measuring the extension and retraction process of the adjustment lever 1.

[0072] Obtain the spatial position of the steering wheel 10 in the vehicle's cockpit, including:

[0073] Acquire the current position data detected by the position measuring device;

[0074] Based on the current location data and the correspondence between the location data of the pre-calibrated location measuring device and the spatial position of the steering wheel 10, the spatial position of the steering wheel 10 in the vehicle's cockpit is determined.

[0075] In this embodiment, the position measuring device can measure the extension and retraction process of the adjusting rod 1. During the extension and retraction of the adjusting rod 1, the steering wheel 10 and the adjusting rod 1 move together. For example, when the adjusting rod 1 is not extended or retracted, the position measuring device calibrates the position of the steering wheel 10 as 0. When the adjusting rod 1 is extended, the position measuring device calibrates the position of the steering wheel 10 as "+". When the adjusting rod 1 is retracted, the position measuring device calibrates the position of the steering wheel 10 as "-". Thus, the spatial position of the steering wheel 10 in the vehicle's cockpit can be determined based on the position measuring device.

[0076] Optionally, refer to Figure 3 and Figure 4 As shown, the aforementioned steering wheel position adjustment device may include an adjustment lever 1, an elastic element 2, a cylinder 3, an air source 4, an air pressure sensor, a first valve 5, and a second valve 6. The adjustment lever 1 is used to connect with the steering wheel 10, and the adjustment lever 1 is movably connected to the cylinder 3. The air pressure sensor is installed inside the cylinder 3. The first valve 5 is installed at the inlet of the cylinder 3, and the second valve 6 is installed at the outlet of the cylinder 3. The inlet of the cylinder 3 is connected to the outlet of the air source 4, and the air pressure in the air source 4 is greater than the air pressure in the cylinder 3. The outlet of the cylinder 3 is used to connect with the outside atmosphere.

[0077] Obtain the spatial position of the steering wheel 10 in the vehicle's cockpit, including:

[0078] Acquire the current air pressure data detected by the barometer;

[0079] Based on the current air pressure data and the correspondence between the air pressure data of the pre-calibrated air pressure sensor and the spatial position of the steering wheel, the spatial position of the steering wheel 10 in the vehicle's cockpit is determined.

[0080] In this embodiment, since the inlet of cylinder 3 is connected to the outlet of air source 4, and the air pressure in air source 4 is greater than the air pressure in cylinder 3, the outlet of cylinder 3 is used to connect with the outside atmosphere. Therefore, when the first valve 5 is open and the second valve 6 is closed, the gas in air source 4 flows into cylinder 3, increasing the air pressure in cylinder 3, thus causing the adjusting rod 1 to extend. When the second valve 6 is closed and the first valve 5 is closed, the gas in cylinder 3 flows to the outside, decreasing the air pressure in cylinder 3, and the adjusting rod 1 retracts under the action of the elastic member 2. In other words, the air pressure in cylinder 3 is related to the spatial position of the steering wheel 10 in the vehicle's driver's cabin. By setting an air pressure sensor, the air pressure in cylinder 3 can be detected, thereby determining the spatial position of the steering wheel 10 in the vehicle's driver's cabin.

[0081] In one embodiment, obtaining the driver's head position includes determining the driver's head position using the vehicle's driver monitoring system. That is, in this embodiment, the existing driver monitoring system in the vehicle is used to determine the driver's head position information, eliminating the need for additional equipment and effectively reducing costs.

[0082] Optionally, refer to Figure 3 and Figure 4 As shown, the steering wheel position adjustment device includes an adjustment rod 1, an elastic element 2, a cylinder 3, an air source 4, a first valve 5, and a second valve 6. The adjustment rod 1 is used to connect to the steering wheel 10, and the adjustment rod 1 is movably connected to the cylinder 3. The first valve 5 is provided at the inlet of the cylinder 3, and the second valve 6 is provided at the outlet of the cylinder 3. The inlet of the cylinder 3 is connected to the outlet of the air source 4, and the air pressure in the air source 4 is greater than the air pressure in the cylinder 3. The outlet of the cylinder 3 is used to connect to the outside atmosphere. Controlling the extension and retraction of the steering wheel 10 through the steering wheel position adjustment device includes:

[0083] The first valve 5 is opened and the second valve 6 is closed, so that the gas in the air source 4 flows into the cylinder 3, thereby driving the adjusting rod 1 to move the steering wheel 10 against the elastic force of the elastic element 2 towards the driver; or, the second valve 6 is opened and the first valve 5 is closed, so that the elastic element 2 drives the adjusting rod 1 to move the steering wheel 10 away from the driver.

[0084] In this embodiment, the cylinder drive and the elastic element 2 drive are stable and responsive. When the airbag deploys from the steering wheel 10, the steering wheel 10 can respond quickly and extend or retract in a timely manner to effectively protect the driver and improve the protection effect.

[0085] Optionally, the method provided in this disclosure embodiment can perform the steps of obtaining the first distance between the steering wheel 10 and the driver in real time, and determining the first difference between the first distance and the target distance, namely the above steps S11 and S12. Accordingly, the above step S13 can specifically be: in response to the airbag deployment signal trigger, controlling the extension and retraction of the steering wheel 10 through the steering wheel position adjustment device according to the most recently determined first difference.

[0086] In other words, by obtaining the first distance between the steering wheel 10 and the driver in real time, and determining the first difference between the first distance and the target distance, the time can be effectively shortened, thereby protecting the driver in a timely manner.

[0087] Alternatively, in other embodiments, in response to the airbag deployment signal, the steps of acquiring a first distance between the steering wheel 10 and the driver, and determining a first difference between the first distance and the target distance are initiated; and after obtaining the first difference, the steering wheel 10 is extended or retracted via the steering wheel position adjustment device based on the first difference. That is, in this embodiment, the acquisition of the first distance and the determination of the first difference are performed after the airbag deployment signal is triggered, and this step can be completed in a very short time, hardly affecting the timeliness of the steering wheel 10's extension or retraction.

[0088] Reference Figure 3 and Figure 4 As shown, the aforementioned steering wheel position adjustment device may include an adjustment lever 1, an elastic element 2, a cylinder 3, an air source 4, a first valve 5, and a second valve 6. The adjustment lever 1 is connected to the steering wheel 10 and is movably connected to the cylinder 3. The cylinder 3 has a first valve 5 at its inlet and a second valve 6 at its outlet. The inlet of the cylinder 3 is connected to the outlet of the air source 4, and the air pressure in the air source 4 is greater than the air pressure in the cylinder 3. The outlet of the cylinder 3 is connected to the outside atmosphere. When the first valve 5 is open and the second valve 6 is closed, the gas in the air source 4 flows into the cylinder 3, which can be used to drive the adjustment lever 1 to move the steering wheel 10 against the elastic force of the elastic element 2 towards the driver. When the second valve 6 is open and the first valve 5 is closed, the elastic element 2 can be used to drive the adjustment lever 1 to move the steering wheel 10 away from the driver.

[0089] In the above technical solution, because the air pressure in the air source 4 is greater than the air pressure in the cylinder 3, when the first valve 5 is open and the second valve 6 is closed, the gas in the air source 4 flows into the cylinder 3. The gas in the cylinder 3 can drive the adjusting rod 1 to move, thereby causing the steering wheel 10 to overcome the elastic force of the elastic element 2 and move towards the driver, thus preventing the steering wheel from being too far from the driver and failing to provide effective protection. When the second valve 6 is open and the first valve 5 is closed, the elastic element 2 can be used to drive the adjusting rod 1 to move the steering wheel 10 away from the driver, thereby preventing the steering wheel from being too close to the driver and causing excessive impact, resulting in a higher safety factor.

[0090] In one implementation, reference Figure 4As shown, the adjusting rod 1 is integrally formed with the piston rod of the cylinder 3 and includes a rod body 11 and a flange plate 12. One end of the rod body 11 is connected to the steering wheel 10, and the other end of the rod body 11 is connected to the flange plate 12. The outer edge of the flange plate 12 can seal against the inner peripheral wall of the cylinder 3 and can slide relative to it. The flange plate 12 can define a gas chamber 30 with the cylinder 3. The inlet and outlet of the cylinder 3 are connected to the gas chamber 30. When the first valve 5 is open and the second valve 6 is closed, the gas in the air source 4 flows into the cylinder 3. The gas in the gas chamber 30 pushes the flange plate 12 to move. Since the flange plate 12 is connected to the rod body 11, and the rod body 11 is connected to the steering wheel 10, it can drive the steering wheel 10 to move towards the driver. When the first valve 5 is closed and the second valve 6 is open, the elastic element 2 drives the adjusting rod 1 to drive the steering wheel 10 to move away from the driver.

[0091] Optionally, refer to Figure 3 and Figure 4 As shown, the cylinder 3 includes a cover plate 31 and a cylinder body 32 with an opening. The cylinder body 32 includes a cylinder base plate 321 and a cylinder side plate 322 connected to each other. The inlet and outlet of the cylinder 3 are formed on the cylinder base plate 321. The outer edge of the flange plate 12 can be sealed and fitted with the inner peripheral wall of the cylinder side plate 322 and can slide against each other. The cover plate 31 is connected to the cylinder side plate 322 and seals the opening. A cover plate hole is formed on the cover plate 31. The rod 11 passes through the cover plate hole from the cylinder body 32 for connection with the steering wheel 10. The cylinder 3 has a simple structure and can effectively extend and retract with the adjusting rod 1. In addition, the cylinder driving method responds quickly and can effectively reduce the response time.

[0092] Optionally, the elastic element 2 is disposed between the cover plate 31 and the flange plate 12; the elastic element 2 includes a coil spring, which is sleeved on the rod body 11 and its two ends are respectively used to abut against the inner wall of the cover plate 31 and the flange plate 12. When the adjusting rod 1 moves toward the direction closer to the driver, the coil spring is compressed by force. When the second valve 6 is opened and the first valve 5 is closed, the coil spring restores its elastic deformation and drives the adjusting rod 1 to move the steering wheel 10 away from the driver.

[0093] Optionally, refer to Figure 4 As shown, the cylinder 3 also includes a stop member 33, which is connected to the inner wall of the cover plate 31 and / or the inner wall of the cylinder side plate 322, and is used to abut against the flange plate 12. For example, the stop member 33 is configured as a stop ring, and the rod 11 and the coil spring are both disposed inside the stop ring. By providing the stop member 33, the problem of failure due to excessive compression of the elastic member 2 can be effectively avoided; in addition, the stop member 33 can be constructed in any suitable shape and structure, and this disclosure does not limit it.

[0094] In other embodiments, the steering wheel position adjustment device further includes a controller. The first valve 5 and the second valve 6 are electrically connected to the controller. The controller can control the first valve 5 to open or close, and the controller can also control the second valve 6 to open or close. For example, when the vehicle is involved in a collision and the airbags deploy, after the controller receives the airbag deployment signal, it controls the first valve 5 or the second valve 6 to open or close, thereby driving the steering wheel 10 closer to or further away from the driver, to prevent the airbags from being too close or too far from the driver.

[0095] Optionally, refer to Figure 3 As shown, the steering wheel position adjustment device also includes a connecting pipe 7. One end of the connecting pipe 7 is connected to the inlet of the cylinder 3, and the other end of the connecting pipe 7 is connected to the outlet of the air source 4. The inlet of the air source 4 is used to connect to the outlet of the vehicle's air compressor. The connection pipe 7 facilitates the connection between the cylinder 3 and the air source 4.

[0096] In another embodiment, refer to Figure 3 As shown, the steering wheel position adjustment device also includes a third valve 8, which is located at the end of the connecting pipe 7 near the air source 4. Opening or closing the third valve 8 facilitates the opening or closing of the connecting pipe 7.
