Description

Technical Field

[0001] The present application relates to the technical field of automobile parts, and in particular to a method for optimizing the profile of a secondary instrument panel armrest and an electronic device. Background Art

[0002] At present, the auxiliary instrument panel is an important structure in the car interior. The auxiliary instrument panel is mainly arranged between the front passengers, that is, between the two front seats, so that the supplies of the front passengers can be placed in the groove on the auxiliary instrument panel, or for the front passengers to support. When designing the first row of space in a car, due to the limitation of the seats, the Y-dimension of the auxiliary instrument panel between the two seats is often small. In order to highlight the sense of luxury and meet the requirements of storage space, the auxiliary instrument panel is usually required to be as wide as possible, and a double armrest is selected. In addition, with the increasing requirements for safety, a remote airbag needs to be arranged between the two seats, which will further reduce the width of the auxiliary instrument panel.

[0003] In the related art, the console armrest of the auxiliary instrument panel is a moving part with a complex structure. In the early analysis, it is usually found that the movement clearance between the CAS surface and the surrounding environmental parts is too small, and no matter how the shaft position is adjusted, the movement clearance requirement cannot be met. At this time, without reducing the Y-width of the armrest, repeated communication between the modeling and engineering is required to adjust the armrest profile and perform movement verification. The adjustment process is relatively complicated and time-consuming. Summary of the invention

[0004] In view of one of the defects existing in the prior art, the purpose of the present application is to provide a method for optimizing the armrest profile of a secondary instrument panel and an electronic device, so as to solve the problem that the armrest profile optimization process in the related art is relatively complicated and time-consuming.

[0005] The first aspect of the present application provides a method for optimizing the profile of a sub-instrument panel armrest, which is used for optimizing the profile of a split armrest of a sub-instrument panel CONSOLE, and comprises the steps of:

[0006] Obtain the CAS surface and layout parameters of the CONSOLE, wherein the layout parameters include a safety gap between the armrest and surrounding environmental parts when the armrest is fully opened;

[0007] Draw a CONSOLE layout section based on the above CAS surface, and determine the position of the rotation axis based on the CONSOLE layout section;

[0008] Perform motion check on the handrail according to the above-mentioned rotation axis position;

[0009] When the distance between the motion envelope of the handrail and the surrounding environment is less than the safety gap, the CAS surface is optimized until the distance between the motion envelope of the handrail and the surrounding environment is greater than or equal to the safety gap.

[0010] In some embodiments, before optimizing the CAS plane, the method further includes:

[0011] An analysis model of the profile parameters of a single-sided handrail and the increased size in the Y direction when the handrail is opened is constructed to optimize the above-mentioned CAS surface.

[0012] In some embodiments, the above-mentioned construction of the analysis model of the profile parameters of the single-side handrail and the increased size in the Y direction when the handrail is in the open state specifically includes:

[0013] The intersection of the tangent line on the upper surface of the handrail and the tangent line on the side is introduced as a control point, and the first relationship model and the second relationship model are constructed respectively;

[0014] The first relationship model represents the corresponding relationship between the position of the control point relative to the rotation axis and the above profile parameters when the armrest on this side is closed:

[0015] The second relationship model represents the corresponding relationship between the position of the control point relative to the rotation axis and the increased size in the Y direction when the armrest on this side is fully opened;

[0016] The first relational model is brought into the second relational model and transformed to obtain the above analysis model.

[0017] In some embodiments, the above analysis model is:

[0018]

[0019] Among them, L0 is the increased dimension in the Y direction when the single-sided armrest is in the open state; A1 is the horizontal tangential angle of the upper surface of the armrest on this side; A2 is the vertical tangential angle of the side of the armrest on this side; A3 is the maximum opening angle of the armrest; L1 is the width of the armrest in the closed state; L2 is the Y-direction distance from the rotation axis of this side to the outer surface of the armrest on this side; H1 is the Z-direction distance from the rotation axis of this side to the outer surface of the armrest on this side; H2 is the Z-direction height of the armrest.

[0020] In some embodiments, the first relationship model is:

[0021]

[0022]

[0023] Among them, according to get:

[0024]

[0025] X is the Y-direction distance from the control point to the outer surface of the handrail when the handrail is closed; α is the angle between the line connecting the control point and the rotation axis and the vertical line; R is the distance from the control point to the rotation axis; L0 is the Y-direction increase in the single-sided handrail when it is open; A1 is the horizontal tangent angle of the upper surface of the handrail on that side; A2 is the vertical tangent angle of the side of the handrail on that side; A3 is the maximum opening angle of the handrail; L1 is the width of the handrail when it is closed; L2 is the Y-direction distance from the rotation axis on that side to the outer surface of the handrail on that side; H1 is the Z-direction distance from the rotation axis on that side to the outer surface of the handrail on that side; H2 is the Z-direction height of the handrail.

[0026] In some embodiments, the second relationship model is:

[0027] sin(π-A3-α)=(L0+L2) / R.

[0028] In some embodiments, optimizing the CAS plane specifically includes:

[0031] In some embodiments, the above preconfigured iteration method is:

[0032] Each initial profile parameter is iteratively processed using a preset iteration step size for each profile parameter.

[0033] In some embodiments, the above-mentioned profile parameters include the horizontal tangent angle of the upper surface of the handrail and the vertical tangent angle of the side of the handrail.

[0036] Draw a CONSOLE layout section based on the above CAS surface, and determine the position of the rotation axis based on the CONSOLE layout section;

[0037] Perform motion check on the handrail according to the above-mentioned rotation axis position;

Therefore, by optimizing the armrest surface modeling, the distance between the armrest and the surrounding environmental parts when the armrest is fully opened is reduced, which not only simplifies the optimization process, but also greatly shortens the optimization time and saves time costs.

[0052] In order to make the purpose, technical solutions and advantages of the present application clearer, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. In addition, the technical features involved in each embodiment of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0053] The embodiment of the present application provides a method for optimizing the profile of an auxiliary instrument panel armrest, which can solve the problem in the related art that the armrest profile optimization process is relatively complicated and time-consuming.

[0054] like Figure 1 As shown, the auxiliary instrument panel armrest profile optimization method of this embodiment is used for optimizing the split armrest profile of the auxiliary instrument panel CONSOLE, and the method comprises the steps of:

[0055] S1. Obtain the CAS surface and layout parameters of the CONSOLE, wherein the above-mentioned layout parameters include a safety gap between the armrest and the surrounding environment when the armrest is fully opened.

[0056] Preferably, the preliminary design input includes the CAS surface of the CONSOLE, and may also include the CAS surface of the seat, the driver's R point, the seat belt buckle, etc. Optionally, the surrounding environment part is a seat.

[0057] S2. Draw a CONSOLE layout section according to the CAS surface of the CONSOLE, and determine the position of the rotation axis according to the CONSOLE layout section.

[0058] In this embodiment, the CONSOLE layout section is drawn according to the input CAS surface of the CONSOLE, which must meet the requirements of human-machine layout, storage space, and clearance with the surroundings, and the position of the rotation axis is obtained accordingly.

[0059] S3. Perform motion calibration on the handrail according to the above-mentioned rotation axis position.

[0060] Among them, when the motion check in space meets the requirements, the safety gap between the armrest and the seat and the seat belt buckle can be guaranteed. In this embodiment, the motion check is to check the kinematic correctness from the perspective of the whole vehicle, and also to check the motion interference of components or parts with relative motion. Since the motion check is related to whether the components can work normally, it must be taken seriously.

[0061] S4. When the distance between the handrail motion envelope and the surrounding environment is less than the safety gap, optimize the above CAS surface until the distance between the handrail motion envelope and the surrounding environment is greater than or equal to the above safety gap. At this time, it indicates that the determined CONSOLE section design meets the requirements.

[0062] Among them, when the motion envelope of the armrest interferes with the surrounding environment, it indicates that the distance between the motion envelope of the armrest and the surrounding environment is a negative number, that is, the distance between the armrest and the surrounding environment in the fully opened state is a negative number.

[0063] Optionally, when the above safety gap is 0, it indicates that the armrest does not interfere with the surrounding environment when it is fully opened, that is, the motion verification is qualified.

[0064] In this embodiment, after optimizing the CAS surface, a new CONSOLE layout section can be drawn based on the optimized CAS surface, and then a new rotation axis position can be determined. Then, the handrail can be motion-checked again, and the distance between the handrail motion envelope and the surrounding environment is compared with the size of the safety gap.

[0065] The method of this embodiment, after obtaining the CAS surface and layout parameters of the CONSOLE, the CONSOLE layout section can be drawn according to the CAS surface to determine the position of the rotation axis; then the handrail is motion-checked according to the position of the rotation axis. When the distance between the handrail motion envelope and the surrounding environmental parts is less than the safety gap, the CAS surface can be optimized according to the profile parameters of the single-sided handrail and the analysis model of the increased size in the Y direction of the handrail on that side when it is fully opened, and the CONSOLE layout section is drawn again until the distance between the handrail motion envelope and the surrounding environmental parts is greater than or equal to the safety gap between the handrail and the surrounding environmental parts when it is fully opened. Therefore, without reducing the Y-width of the handrail, the distance between the handrail and the surrounding environmental parts when it is fully opened can be reduced by optimizing the handrail profile modeling, which not only simplifies the optimization process, but also greatly shortens the optimization time and saves time costs.

[0066] Based on the above embodiment, in this embodiment, before optimizing the above CAS surface, the following steps are also included:

[0067] An analysis model of the profile parameters of a single-sided handrail and the increased size in the Y direction when the handrail is opened is constructed to optimize the above-mentioned CAS surface.

[0068] Preferably, the above-mentioned construction of the analysis model of the profile parameters of the single-side handrail and the increased size in the Y direction when the handrail is in the open state specifically includes the following steps:

[0069] Firstly, the intersection of the upper surface tangent and the side tangent of the single-side handrail is introduced as a control point to construct the first relationship model and the second relationship model respectively. The upper surface tangent and the side tangent are located in the same vertical plane, which is perpendicular to the forward direction of the vehicle.

[0070] In this embodiment, the vehicle forward direction is the X direction, the direction perpendicular to the X direction in the horizontal plane is the Y direction, and the vertical direction is the Z direction. Optionally, the control point is the intersection of the section on the upper surface of the single-sided handrail, the side section, and the YOZ plane where the highest point of the handrail is located.

[0071] Among them, the above-mentioned first relationship model represents the correspondence between the position of the control point relative to the rotation axis and the above-mentioned surface parameters when the side armrest is in the closed state: the above-mentioned second relationship model represents the correspondence between the position of the control point relative to the rotation axis and the increased dimension in the Y direction when the side armrest is in the fully open state.

[0072] Then, the first relational model is brought into the second relational model and transformed to obtain the profile parameters of the above-mentioned single-sided handrail and the Y-direction increased dimension analysis model of the handrail on this side in the fully opened state.

[0073] like Figure 2 As shown, after the split armrest is flipped open around the rotation axis 1, the Y-axis width of the armrest will increase, as shown in state 2 after the armrest is flipped open. Among them, L0 is the Y-axis increase size when the single-sided armrest is in the open state. A1 is the horizontal tangent angle of the upper surface of the armrest on this side; A2 is the vertical tangent angle of the side of the armrest on this side; A3 is the maximum opening angle of the armrest, and A3 is generally about 80°; L1 is the width of the armrest in the closed state, which is related to the width of the vehicle and is generally maximized in a limited space; L2 is the Y-axis distance from the rotation axis on this side to the outer surface of the armrest on this side; H1 is the Z-axis distance from the rotation axis on this side to the outer surface of the armrest on this side; H2 is the Z-axis height of the armrest.

[0074] In this embodiment, L1, L2, H1, H2, and A3 are all design values. Therefore, the profile parameters of the above-mentioned single-sided handrail include the horizontal tangent angle A1 of the upper surface of the handrail and the vertical tangent angle A2 of the side of the handrail.

[0075] In this embodiment, the above analysis model is:

[0076]

[0077] like Figure 3As shown, since the direction of the handrail profile is related to L0, in order to simplify the relationship between L0 and A1 and A2, the handrail model is simplified to obtain a simplified handrail model.

[0078] like Figure 4 The simplified model of the single-sided handrail shown in the figure can more clearly show the relationship between the parameters of the handrail profile and the positional relationship between the control point 3 and the rotation axis 1 after the control point 3 is introduced. Among them, L1 / 2 is the single-sided width of the handrail in the closed state. At this time, the control point related parameters are defined, including the Y-direction distance X from the control point to the outer surface of the handrail in the closed state, the angle α between the line connecting the control point and the rotation axis and the vertical line, and the distance R from the control point to the rotation axis, and are solved.

[0079] In this embodiment, the first relationship model representing the corresponding relationship between the position of the control point relative to the rotation axis and the profile parameter when the armrest is in the closed state is:

[0080]

[0081]

[0082] Among them, according to get:

[0083]

[0084] Then we can get:

[0085]

[0086]

[0087] Wherein, X is the Y-direction distance from the control point to the outer surface of the side armrest when the armrest is closed; α is the angle between the line connecting the control point and the side rotation axis and the vertical line; and R is the distance from the control point to the side rotation axis.

[0088] like Figure 5 As shown, in this embodiment, the state after rotation is further analyzed. When the armrest is in the open state, the distance R from the control point to the rotation axis remains unchanged. At this time, the angle between the line connecting the control point and the rotation axis and the upward vertical line is the sum of α and A3. According to the positional relationship between the control point 3 and the rotation axis 1 in the state 2 after the armrest is flipped, the second relationship model representing the corresponding relationship between the position of the control point relative to the rotation axis and the increased size in the Y direction when the armrest is fully opened is obtained:

[0089] sin(π-A3-α)=(L0+L2) / R

[0090] That is, L0=Rsin(π-A3-α)-L2.

[0091] In this embodiment, the Y-direction increase dimension L0 of the above-mentioned single-sided armrest in the open state is strongly correlated with the horizontal tangential angle A1 of the upper surface of the side armrest and the vertical tangential angle A2 of the side edge of the side armrest.

[0092] Preferably, in order to ensure the comfort of the armrest, the angle of A1 is generally 0° to 6°.

[0093] like Figure 6 As shown, when the vertical tangent angle A2 of the side of the armrest is a constant, within the angle range of 0° to 6°, as the horizontal tangent angle A1 of the upper surface of the side armrest increases, L0 gradually decreases. In some embodiments, in a limited space, selecting a larger A1 can make the Y-direction width of the armrest in the closed state larger.

[0094] like Figure 7 As shown, further, when the horizontal tangent angle A1 of the upper surface of the armrest is a constant value, as the vertical tangent angle A2 of the side of the armrest increases, L0 gradually decreases. In this embodiment, in order to ensure sufficient armrest box space, it is generally required that A2 is as small as possible. In some embodiments, when the storage space requirement is met, a larger A2 is selected to make the Y-direction width of the armrest in the closed state larger.

[0095] Preferably, the Y-direction distance L2 from the above-mentioned rotating shaft to the outer surface of the side armrest is greater than or equal to 10 mm, the Z-direction distance H1 from the above-mentioned rotating shaft to the outer surface of the side armrest is greater than or equal to 26 mm, and the Z-direction height H2 of the above-mentioned armrest is greater than or equal to 40 mm.

[0096] Optionally, the Y-direction distance L2 from the rotating shaft to the outer surface of the side armrest is 10 mm, the Z-direction distance H1 from the rotating shaft to the outer surface of the side armrest is 26 mm, and the Z-direction height H2 of the armrest is 40 mm.

[0097] In other embodiments, the Y-direction distance L2 from the rotation axis to the outer surface of the side armrest is 15 mm, the Z-direction distance H1 from the rotation axis to the outer surface of the side armrest is 30 mm, and the Z-direction height H2 of the armrest is 45 mm.

[0098] Based on the above embodiment, in this embodiment, when the distance between the motion envelope of the armrest and the surrounding environment is less than the safety gap, the above CAS surface needs to be optimized.

[0099] In this embodiment, optimizing the above CAS surface specifically includes the following steps:

[0100] First, the surface parameters before optimization are obtained as initial surface parameters.

[0101] Then, the initial profile parameters are iteratively processed using a preconfigured iteration method, and the iterative profile parameters are input into the above analysis model to obtain the iterative Y-axis increase size, and then the calculated distance between the handrail and the surrounding environment parts when the handrail is fully opened is obtained, until the calculated distance is greater than or equal to the safety gap.

[0102] Preferably, the above-mentioned preconfigured iteration method is: using a preset iteration step size of each profile parameter to iteratively process each initial profile parameter respectively.

[0103] Preferably, in the above, the iteration step sizes of the horizontal tangential angle of the upper surface of the handrail and the vertical tangential angle of the side edge of the handrail may be the same or different.

[0104] like Figure 8 As shown, the optimization of the CAS surface in this embodiment specifically includes the following steps:

[0105] A1. Get the current profile parameters;

[0106] A2. Increase the iteration step of the current profile parameters, input the obtained iterative profile parameters into the analysis model, and output the increased size in the Y direction;

[0107] A3. According to the increased dimension in the Y direction, calculate the distance between the armrest and the surrounding environment when it is fully opened;

[0108] A4. Determine whether the calculated distance is greater than or equal to the safety gap. If so, turn to A5; otherwise, A5 turns to A1.

[0109] A5. Obtain the current profile parameters to generate an optimized CAS surface.

[0110] Optionally, optimizing the CAS surface specifically includes:

[0111] First, obtain the current horizontal tangent angle A1 of the upper surface of the handrail and the vertical tangent angle A2 of the side of the handrail, and set the first iteration step of the horizontal tangent angle A1 of the upper surface of the handrail and the second iteration step of the vertical tangent angle A2 respectively.

[0112] Then, the horizontal tangent angle A1 on the upper surface of the handrail is increased by the first iteration step to obtain the iterative A1, and the vertical tangent angle A2 is increased by the second iteration step to obtain the iterative A2. The iterative A1 and A2 are input into the analysis model to output the new Y-axis increased size.

[0113] Finally, according to the new Y-axis increase size, the new calculated distance between the armrest and the surrounding environment in the fully opened state is calculated, and it is determined whether the new calculated distance is greater than or equal to the safety gap. If the new calculated distance is greater than or equal to the safety gap, the A1 and A2 at this time are obtained to generate the optimized CAS surface, indicating that the CAS surface optimization is completed; if the new calculated distance is less than the safety gap, the corresponding iteration step size is increased again with the current A1 and A2 until the CAS surface optimization is completed.

[0114] In this embodiment, the distance between the environmental parts on both sides of the armrest is a fixed spacing value, that is, the sum of twice the increased dimension in the Y direction and the width of the armrest in the closed state must be less than or equal to the above-mentioned fixed spacing value.

[0115] When the safety gap is 0, the sum of twice the Y-axis increase and the width of the handrail in the closed state must be less than or equal to the above spacing value.

[0116] When the safety gap is greater than 0, the sum of twice the increased size in the Y direction and the width of the handrail in the closed state must be less than or equal to the difference between the above-mentioned spacing value and twice the safety gap.

[0117] Optionally, if the horizontal tangential angle of the upper surface of the armrest and the vertical tangential angle of the side of the armrest increase to their respective preset maximum values, and the calculated distance between the armrest and the surrounding environment when the armrest is fully opened is still less than the safety gap, it indicates that the width of the armrest in the closed state is set too large and needs to be reduced to increase the above-mentioned safety gap.

[0118] At this time, the horizontal tangent angle of the upper surface of the handrail and the vertical tangent angle of the side of the handrail can be kept unchanged, and the width L1 of the handrail in the closed state is iterated according to the preset reduction amount. After each iteration, the new width L1 of the handrail in the closed state is input into the above analysis model to obtain the new Y-axis increase size L0, and then the calculated distance between the handrail and the surrounding environment parts in the fully open state is obtained, until the calculated distance is greater than or equal to the safety gap. At this time, the width L1 of the handrail in the closed state is the optimized width value, and then the new CAS surface of the CONSOLE and the new rotation axis position are obtained to perform handrail motion verification.

[0119] In some embodiments, when it is found that the safety gap between the CONSOLE and the seat is too small, the armrest width is directly reduced, resulting in the inability to meet the storage space requirement.

[0120] The auxiliary instrument panel armrest profile optimization method of this embodiment establishes a simplified model for armrest motion analysis and establishes the relationship between armrest profile parameters and the unilateral Y-direction increase size when the armrest is fully opened, so that the armrest motion can be quantitatively analyzed to effectively guide the modeling to optimize the CONSOLE armrest profile, avoid repeated communication between the modeling and the engineering, and save time costs. At the same time, it is achieved that the distance between the armrest and the surrounding environment in the fully opened state is reduced by optimizing the armrest profile modeling without reducing the Y-direction width of the armrest as much as possible, greatly shortening the optimization time of the armrest profile.

[0121] The present application also provides an embodiment of an electronic device for optimizing the profile of a secondary instrument panel armrest, the electronic device comprising a processor and a memory, the processor executing a code in the memory to implement the following secondary instrument panel armrest profile optimization method:

[0122] Obtain the CAS surface and layout parameters of the CONSOLE, wherein the layout parameters include a safety gap between the armrest and surrounding environmental parts when the armrest is fully opened;

[0123] Draw a CONSOLE layout section based on the above CAS surface, and determine the position of the rotation axis based on the CONSOLE layout section;

[0124] Perform motion check on the handrail according to the above-mentioned rotation axis position;

[0125] When the distance between the motion envelope of the handrail and the surrounding environment is less than the safety gap, the CAS surface is optimized until the distance between the motion envelope of the handrail and the surrounding environment is greater than or equal to the safety gap.

[0126] In this embodiment, if the motion envelope of the armrest interferes with the surrounding environment, it means that the distance between the motion envelope of the armrest and the surrounding environment is a negative number, that is, the distance between the armrest and the surrounding environment in the fully opened state is a negative number.

[0127] Optionally, the processor executing the code in the memory may further implement the following auxiliary instrument panel armrest profile optimization method:

[0128] Before optimizing the above CAS surface, it also includes constructing the surface parameters of the single-side handrail and the analysis model of the increased size in the Y direction when the handrail on this side is in the open state.

[0129] Optionally, the processor executing the code in the memory may further implement the following auxiliary instrument panel armrest profile optimization method:

[0130] The intersection of the tangent line on the upper surface of the handrail and the tangent line on the side is introduced as a control point, and the first relationship model and the second relationship model are constructed respectively;

[0131] The first relationship model represents the corresponding relationship between the position of the control point relative to the rotation axis and the above profile parameters when the armrest on this side is closed:

[0132] The second relationship model represents the corresponding relationship between the position of the control point relative to the rotation axis and the increased size in the Y direction when the armrest on this side is fully opened;

[0133] The first relational model is brought into the second relational model and transformed to obtain the above analysis model.

[0134] Optionally, the processor executing the code in the memory may further implement the following auxiliary instrument panel armrest profile optimization method:

[0135] Obtaining the surface parameters before optimization as initial surface parameters;

[0136] The initial profile parameters are iteratively processed using a preconfigured iteration method, and the iterative profile parameters are input into the above analysis model to obtain the iterative Y-axis increase size, and then obtain the calculated distance between the handrail and the surrounding environment parts when the handrail is fully opened, until the calculated distance is greater than or equal to the safety gap.

[0137] Optionally, the processor executing the code in the memory may further implement the following auxiliary instrument panel armrest profile optimization method:
