The value of the second included angle at this time is obtained and used as the fixed included angle of the bearing surface relative to the X-axis of the car.

[0046] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0047] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0048] Example 1

[0049] As mentioned in the background section, to address the problem of collisions between mobile phones and wireless charging structures caused by sudden braking in existing technologies, this application proposes a wireless charging structure design method to prevent damage to communication devices. The wireless charging structure 1 has a load-bearing surface 2, such as... Figure 1 As shown. Combined with Figure 1 and Figure 2 The method includes the following steps:

[0050] S100: A first angle value is preset between the bearing surface 2 of the wireless charging structure 1 and the X-axis of the vehicle; the first angle is an acute angle; the opening of the first angle faces away from the seat. In the vehicle body design, the right-hand rule is used to determine the coordinate system, where the X-axis is the length direction of the vehicle and the Y-axis is the width direction. In this embodiment, the bottom end 101 of the wireless charging structure 1 is placed along the Y-axis direction of the vehicle, and the length direction of the wireless charging structure 1 is parallel to the X-axis direction of the vehicle. In certain specific scenarios, the length of the bottom end 101 of the wireless charging structure is 221 mm, the length of the top end 102 of the wireless charging structure is 250 mm, the communication device is a mobile phone, and the first angle is the angle formed between the X-axis of the vehicle and the bearing surface 2, with the first angle value between 0 degrees and 90 degrees.

[0051] S101: After driving the vehicle at an initial speed for a first preset time, the initial speed is reduced to a second speed at a first rate to simulate a scenario of emergency braking. In certain specific scenarios, the road on which the vehicle travels is a sufficiently long straight section. The initial speed is set to 50 km / h. After the vehicle travels at the initial speed of 50 km / h for 5 seconds, the brakes are applied, and the vehicle speed is reduced to 0 km / h at the first rate of 4 m / s² within 3.5 seconds.

[0052] S102: During the process from the initial speed to the second speed, obtain the first displacement of the communication device relative to the length direction of the bearing surface 2 on the wireless charging structure 1. Specifically, when the first angle is formed between the X-axis of the vehicle and the bearing surface 2, place the mobile phone on the bearing surface 2, and test the displacement of the mobile phone relative to the length direction of the bearing surface 2 after the vehicle brakes suddenly during driving; this displacement is the first displacement.

[0053] S103: Obtain a correction coefficient based on the first displacement; and correct the first included angle value based on the correction coefficient to obtain a second included angle value. In certain specific scenarios, depending on the range of the first displacement, multiple correction databases corresponding to the first displacement within each range are provided. Each correction database includes correction coefficients corresponding to different numerical intervals of the first displacement within that range. Therefore, after obtaining the first displacement, the corresponding correction database can be found based on its range, and the corresponding correction coefficient can be found within the correction database based on the first displacement interval. Then, the included angle value is adjusted based on the correction coefficient. Optionally, the correction coefficient can be an angle change amount; adding the original included angle value to the angle change amount yields the adjusted included angle value. Alternatively, the correction coefficient can be an angle change factor; multiplying the original included angle value by the angle change factor yields the adjusted included angle value. This embodiment does not impose specific limitations on this. Furthermore, the values ​​of each correction coefficient in the database can be preset according to actual needs; this embodiment does not impose specific limitations on this.

[0054] S104: Adjust the angle between the bearing surface 2 of the wireless charging structure 1 and the X-axis of the vehicle to the second angle value. When the obtained first displacement is too large, the angle between the X-axis of the vehicle and the bearing surface 2 needs to be increased; when the obtained first displacement is too small, the angle between the X-axis of the vehicle and the bearing surface 2 needs to be decreased. This solution corrects the angle between the X-axis of the vehicle and the bearing surface 2 by testing the displacement of the communication device relative to the length direction of the bearing surface 2 under rapid acceleration and deceleration of the vehicle, thereby avoiding collision between the communication device and the edge of the wireless charging structure 1, which could cause damage to the communication device.

[0055] In addition, to ensure that the mobile phone does not collide with the top 102 and bottom 101 of the wireless charging structure during vehicle operation, in addition to testing the rapid deceleration situation, it is also necessary to test the rapid acceleration situation. The rapid acceleration test is to drive the vehicle from 0 km / h to 100 km / h in 7 to 8 seconds; the similarities with the rapid deceleration test will not be repeated.

[0056] Furthermore, after adjusting the angle between the bearing surface 2 of the wireless charging structure 1 and the X-axis of the vehicle to the second angle value, the method further includes:

[0057] After repeatedly driving the vehicle at the initial speed for the first preset time, the initial speed is reduced to the second speed at the first rate. In certain specific scenarios, the angle between the X-axis of the vehicle and the bearing surface 2 is adjusted to the second angle value, and the test is carried out again on a straight road. The initial speed is set to 50 km / h. After the vehicle travels at the initial speed of 50 km / h for 5 seconds, the brake is applied and the vehicle speed is reduced to 0 km / h at the first rate of 4 m / s² within 3.5 seconds.

[0058] During the process from the initial velocity to the second velocity, the second displacement of the communication device relative to the bearing surface 2 on the wireless charging structure 1 in the length direction is obtained; specifically, as shown in... Figure 1 As shown, the second included angle is the angle formed between the length direction of the bearing surface 2 and the X-axis direction of the car. The mobile phone is placed on the bearing surface 2, and the displacement of the mobile phone relative to the length direction of the bearing surface 2 after the vehicle brakes suddenly during driving is the second displacement.

[0059] If the second displacement meets the requirements, the current second included angle value is obtained and used as the fixed included angle between the bearing surface 2 of the wireless charging structure and the X-axis of the car; otherwise, the process returns to steps S101-S104 until the requirements are met. In certain specific scenarios, when the second displacement of the mobile phone relative to the bearing surface 2 in the length direction does not need to be corrected, the corresponding second included angle value is obtained. That is, when the included angle between the X-axis of the car and the bearing surface 2 is the second included angle value, the communication device can avoid collision with the top 102 and the bottom 101 of the wireless charging structure.

[0060] Table 1

[0061] First displacement range Correct the database First displacement ≥ first preset threshold First Database First displacement < second preset threshold Second Database

[0062] As shown in Table 1, the step of obtaining the correction coefficient based on the first displacement further includes:

[0063] When the first displacement is determined to be greater than or equal to a first preset threshold, a first database is invoked to obtain a first correction coefficient. The first database includes multiple displacement range values ​​and the first correction coefficient corresponding to each displacement range value. The first correction coefficient is used as the correction coefficient. The first preset threshold represents the maximum displacement that can prevent damage to the communication device and ensure charging effectiveness. In certain specific scenarios, the first preset threshold is set to 5 mm. When the obtained first displacement is greater than or equal to 5 mm, the communication device displacement is too large, making it prone to collision with the wireless charging structure or potentially sliding out of the rechargeable area on the wireless charging structure. In this case, the first database is invoked to obtain the first correction coefficient, thereby adjusting the angle between the vehicle's X-axis and the bearing surface 2 accordingly.

[0064] Further, the step of obtaining the correction coefficient based on the first displacement includes:

[0065] When the first displacement is determined to be less than a second preset threshold, a second database is invoked to obtain a second correction coefficient; the second preset threshold is less than the first preset threshold; wherein, the second database includes: multiple displacement range values ​​and the second correction coefficient corresponding to each displacement range value; the second correction coefficient is used as the correction coefficient. In certain specific scenarios, the second preset threshold is set to 1 mm. When the obtained first displacement is less than 1 mm, it indicates that the displacement of the communication device is very small and will not collide with the wireless charging structure. At this time, the observation angle of the communication device by the people inside the vehicle can be further considered. In order to facilitate the people inside the vehicle to observe the screen of the communication device, the first angle can be raised a little. At this time, the second database is invoked to obtain the second correction coefficient, and the angle between the X-axis of the car and the bearing surface 2 is adjusted accordingly based on the second correction coefficient. Of course, the angle cannot be increased indefinitely, but should be appropriately increased while ensuring that there is no collision and the communication device can charge normally in close contact with the bearing surface.

[0066] This embodiment calls different databases for the two different ranges of the first displacement value. Compared with storing the correction coefficients corresponding to all the first displacement values ​​in one large database, this method, through database subdivision, achieves a layer-by-layer search from the displacement value range to the database, and then to traversing the database. This reduces the time spent traversing the database and enables rapid acquisition of the corresponding correction coefficients, shortening the time required to correct the angle between the vehicle's X-axis and the bearing surface 2. Simultaneously, the two sets of angle ranges and databases correspond to two adjustment purposes: the first set aims to avoid "collisions due to excessive displacement," while the second set aims to "maintain visual appearance even with small displacements." The two databases can be constructed using different calibration methods, improving construction efficiency.

[0067] Furthermore, after obtaining the second displacement of the communication device relative to the bearing surface 2 on the wireless charging structure 1 along its length, if the second displacement is greater than or equal to the second preset threshold and less than the first preset threshold, the second displacement is considered to meet the requirements. The second included angle value at this time is then obtained and used as the fixed included angle between the bearing surface 2 and the vehicle's X-axis. Specifically, when the obtained second displacement is greater than or equal to 1 mm and less than 5 mm, this displacement is considered a normal displacement. Within this displacement range, the communication device does not collide with the wireless charging structure 1 and can charge normally. At this point, the correction of the second included angle value can be stopped, and the angle between the vehicle's X-axis and the bearing surface 2 at this time is set as a fixed angle.

[0068] Under certain specific scenarios, after the above-mentioned emergency braking test, it was finally concluded that: the angle between the X-axis of the car and the bearing surface 2 obtained from the test for a certain car model is 26.7 degrees, the vertical distance from the top of the wireless charging structure 102 to the X-axis of the car is 113.4 mm, and the mobile phone on the wireless charging structure 1 at this angle of the car model can avoid collision with the wireless charging structure during the vehicle's operation and can charge normally, while also taking into account a certain visual effect.

[0069] Example 2

[0070] This embodiment addresses the problem of collisions between mobile phones and wireless charging structures caused by sharp turns in existing technologies, and proposes a wireless charging structure design method.

[0071] Furthermore, such as Figure 1 As shown, the wireless charging structure 1 has baffles 4 on both sides along the Y-axis of the car, combined with Figure 1 and Figure 3 The design method of this embodiment, based on embodiment 1, further includes the following steps:

[0072] S600: The included angle values ​​of the two baffles 4 relative to the Y-axis of the vehicle are preset. These two included angles are acute angles, and their opening directions are far apart. In vehicle body design, the right-hand rule is used to determine the coordinate system, where the Y-axis represents the width direction of the vehicle. In certain specific scenarios, such as... Figure 1 As shown, the distance between the two baffles 4 gradually increases from the bottom 101 and the top 102 of the wireless charging structure. When the vehicle goes through a curve, the mobile phone will shift in the width direction of the bearing surface 2. In order to avoid the mobile phone from colliding with the baffles 4 on both sides and causing damage to the side of the mobile phone, a certain angle needs to be set between the baffles 4 on both sides and the Y-axis of the car. The size of the third included angle is between 0 degrees and 90 degrees.

[0073] S601: Drive the vehicle at a third speed on a curve to simulate a sharp turn. In certain specific scenarios, the road is a curve, and the third speed is set to 40 km / h. The vehicle travels through the curve at the third speed of 40 km / h.

[0074] S602: During cornering, acquire the third displacement of the communication device relative to the width direction of the bearing surface 2 on the wireless charging structure 1. Specifically, when the third angle is formed between the Y-axis of the vehicle and the baffle 4, place the mobile phone on the bearing surface 2, and test the displacement of the mobile phone relative to the width direction of the bearing surface 2 after high-speed cornering during vehicle operation; this displacement is the third displacement. Figure 1 As shown, the wireless charging structure 1 has a baffle 3 in the middle of the bearing surface 2. The baffle 3 extends in the length direction of the bearing surface 2, dividing the charging area of ​​the wireless charging structure 1 into two parts, enabling two mobile phones to be charged simultaneously. When the mobile phone is placed on the bearing surface 2, the side closer to the baffle 3 is in close contact with the baffle 3. When the mobile phone is in high speed and turns during vehicle operation, the displacement of the mobile phone relative to the width direction of the bearing surface 2 is based on the deviation distance of the side of the mobile phone that is initially in close contact with the baffle 3 from the baffle 3.

[0075] S603: Based on the third displacement, obtain a correction coefficient, and based on the correction coefficient, correct the third included angle value to obtain a fourth included angle value; under certain specific scenarios, when the third displacement is within a certain range, there is a corresponding correction database, which includes correction coefficients corresponding to different numerical ranges of the third displacement within that range; therefore, after obtaining the third displacement, the correction database corresponding to it can be found according to its range, and then the correction coefficient corresponding to it can be found in the correction database according to the third displacement range, and then the included angle value can be adjusted according to the correction coefficient.

[0076] In addition, to ensure that the outer wall of the mobile phone does not collide with any part of the wireless charging structure 1 during the vehicle's various driving scenarios, bumpy road tests and speed bump tests can also be performed under certain specific circumstances; the similarities with the curve test will not be repeated here.

[0077] S604: Adjust the angle between the baffle 4 and the vehicle bearing surface 2 along the width direction of the wireless charging structure 1 to the fourth angle value; when the obtained third displacement is too large, the angle between the vehicle Y-axis and the baffle 4 needs to be increased; when the obtained third displacement is too small, the angle between the vehicle Y-axis and the baffle 4 needs to be decreased.

[0078] Specifically, by testing the displacement of the communication device relative to the width direction of the bearing surface 2 when the vehicle is cornering at high speed, the angle between the Y-axis of the car and the baffle 4 is corrected, thereby preventing the communication device from colliding with the edge of the wireless charging structure 1 and causing damage to the communication device.

[0079] Furthermore, after adjusting the angle between the baffle 4 of the wireless charging structure 1 along its width direction and the vehicle bearing surface 2 to the fourth angle value, the method further includes:

[0080] Repeatedly drive the vehicle to turn while driving at the third speed; under certain specific circumstances, adjust the angle between the Y-axis of the car and the baffle 4 to the fourth angle value, and then test again on the curve; set the third speed to 40 km / h, and drive the vehicle through the curve at the third speed of 40 km / h.

[0081] During the turning process, the fourth displacement of the communication device relative to the width direction of the bearing surface 2 on the wireless charging structure 1 is obtained; specifically, when the fourth angle is formed between the Y-axis of the car and the baffle 4, the mobile phone is placed on the bearing surface 2, and the displacement of the mobile phone relative to the width direction of the bearing surface 2 after high-speed cornering during vehicle driving is measured, which is the fourth displacement.

[0082] If the fourth displacement meets the requirements, the fourth included angle value is obtained as the fixed included angle of the baffle 4 of the wireless charging structure 1 relative to the vehicle bearing surface 2; otherwise, the process returns to steps S601-S604 until the requirements are met. In certain specific scenarios, when the fourth displacement of the mobile phone relative to the bearing surface 2 in the width direction does not need to be corrected, the corresponding fourth included angle value is obtained. That is, when the included angle between the Y-axis of the vehicle and the baffle 4 is the fourth included angle value, the communication device can avoid collision with the two side baffles 4 of the wireless charging structure 1.

[0083] Table 2

[0084] Third displacement range Correct the database Third displacement ≥ Fourth preset threshold Fourth Database

[0085] Specifically, as shown in Table 2, the step of obtaining the correction coefficient based on the third displacement includes:

[0086] When the third displacement is determined to be greater than or equal to a fourth preset threshold, a fourth database is invoked to obtain a fourth correction coefficient. The fourth database includes multiple displacement range values ​​and the fourth correction coefficient corresponding to each displacement range value. The fourth correction coefficient is used as the correction coefficient. In certain specific scenarios, the fourth preset threshold is set to 1.5 cm. When the obtained third displacement is greater than 1.5 cm, the fourth database is invoked to obtain the fourth correction coefficient, thereby adjusting the angle between the vehicle's Y-axis and the baffle 4 accordingly.

[0087] Specifically, after obtaining the fourth displacement of the communication device relative to the width direction of the bearing surface 2 on the wireless charging structure 1, if the fourth displacement is less than the fourth preset threshold, the fourth displacement meets the requirements. The fourth included angle value at this time is then obtained and used as the fixed included angle value between the car's Y-axis and the baffle 4. Specifically, when the obtained fourth displacement is less than 1.5 cm, it is considered a normal displacement. Within this displacement range, the communication device will not collide with the wireless charging structure 1 and can charge normally. Therefore, there is no need to further correct the fourth included angle value, and the angle between the car's Y-axis and the baffle 4 at this time can be set as a fixed angle.

[0088] In certain specific scenarios, after the above-mentioned sharp turn test, it was finally concluded that the angle between the Y-axis of the car and the baffle 4 (i.e. the angle between the baffle 4 and the bearing surface 2) obtained from the test for a certain car model is 17.5 degrees. At this angle of the wireless charging structure 1 of the car model, the mobile phone can avoid collision with the wireless charging structure 1 during the vehicle's operation and can be charged normally.

[0089] In certain specific scenarios, the bearing surface 2 is covered with a suede-like material to increase friction and help ensure the stability of the mobile phone on the wireless charging structure 1. At the same time, the bottom end 101 of the wireless charging structure is provided with TPU soft rubber at the contact point with the mobile phone. Taking elasticity into consideration, its hardness is set to 65-70A to ensure that it will not come apart while providing shock absorption for the mobile phone and preventing damage to the bottom of the mobile phone. The TPU soft rubber is fused to the wireless charging structure 1 using a secondary injection molding or two-color injection molding process.

[0090] Example 3

[0091] Based on Embodiments 1 and 2, this application further proposes a wireless charging structure control device, such as... Figure 4 As shown, it includes:

[0092] The first processing module is configured to preset a first angle value between the bearing surface 2 of the wireless charging structure 1 and the X-axis of the vehicle; the first angle is an acute angle; the opening of the first angle faces away from the seat; in certain specific scenarios, the length of the bottom end 101 of the wireless charging structure is 221 mm, the length of the top end 102 of the wireless charging structure is 250 mm, the communication device is a mobile phone, and the first angle is the angle formed between the X-axis of the vehicle and the bearing surface 2, and the value of the first angle is between 0 degrees and 90 degrees.

[0093] The second processing module is configured to drive the vehicle at an initial speed for a first preset time, and then reduce the initial speed to a second speed at a first rate to simulate a vehicle emergency braking scenario. In certain specific scenarios, the road on which the vehicle travels is a sufficiently long straight section, the initial speed is set to 50 km / h, and after the vehicle travels at the initial speed of 50 km / h for 5 seconds, the brake is applied to reduce the vehicle speed to 0 km / h at the first rate of 4 m / s² within 3.5 seconds.

[0094] The first acquisition module is configured to acquire the first displacement of the communication device relative to the length direction of the bearing surface 2 on the wireless charging structure 1 during the process from the initial speed to the second speed. Specifically, when the first angle is formed between the X-axis of the car and the bearing surface 2, the mobile phone is placed on the bearing surface 2, and the displacement of the mobile phone relative to the length direction of the bearing surface 2 after the vehicle brakes suddenly during driving is the first displacement.

[0095] The first output module is configured to obtain a correction coefficient based on the first displacement; and correct the first included angle value based on the correction coefficient to obtain a second included angle value; in certain specific scenarios, if the obtained first displacement is too large or too small, obtain the corresponding correction coefficient at this time, and adjust the included angle between the vehicle X-axis and the bearing surface 2.

[0096] The third processing module is configured to adjust the angle between the bearing surface 2 of the wireless charging structure 1 and the X-axis of the vehicle to the second angle value. When the obtained first displacement is too large, the angle between the X-axis of the vehicle and the bearing surface 2 needs to be increased; when the obtained first displacement is too small, the angle between the X-axis of the vehicle and the bearing surface 2 needs to be decreased. This solution corrects the angle between the X-axis of the vehicle and the bearing surface 2 by testing the displacement of the communication device relative to the length direction of the bearing surface 2 under emergency braking conditions, thereby avoiding collision between the communication device and the edge of the wireless charging structure 1, which would cause damage to the communication device.
