[0045] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0046] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0047] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0048] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0049] During the design phase of new energy vehicle products, almost every project requires several rounds of adjustments to the dashboard design. In the early stages, the dashboard position is often set based on aesthetic considerations, but less consideration is given to layout, performance, and craftsmanship, or the consideration is not deep enough. If the dashboard boundary is found to be unreasonable during the later stage of styling engineering development, it is necessary to return to the styling stage for adjustment, which will inevitably affect the development cost and cycle, and each adjustment will increase the development cycle by at least 20 days.

[0050] According to the above situation, this embodiment provides a dashboard design method, which is based on target parametric design and can quickly complete the layout optimization setting of the dashboard, avoid the risk of repeatedly modifying the dashboard during the styling engineering stage, improve the styling development and design efficiency of new energy vehicles, shorten the product development cycle and achieve the design goals.

[0051] Specifically, the embodiment of the present invention provides a dashboard design method, combining Figure 1The method includes steps 101 to 104:

[0052] Step 101: Obtaining visual field targets, space targets, human body and structure layout information, defrosting and defogging targets, and vehicle configuration information;

[0053] In this embodiment, the visual field target refers to the need to meet the driver's downward visual field requirements when designing the dashboard. The downward visual field is the driver's ability to observe the road, environment, and vehicle conditions through a specific area below the front windshield or around the vehicle body during driving. Figure 4 As mentioned above, the lower field of view of this embodiment is generally greater than or equal to 5 degrees.

[0054] The space target refers to the space requirements that need to be met when designing the dashboard. The space target mainly includes knee space, calf protection space, hand reach and interface space, and foot space. Among them, knee space refers to the movable space of the driver's knees when sitting. Calf protection space refers to the protection space reserved for the calf. Hand reach and interface space refers to the space requirements that need to be met when the driver reaches out to operate different devices, for example, the space requirements that need to be met when the driver reaches out to adjust the air vents of the air conditioner, and the space requirements that need to be met when the driver reaches out to touch the central control screen.

[0055] The human body and structure layout information refers to the human body setting position and the position of the lower body floor. The human body setting position refers to the set driver position. The lower body floor position refers to the position of the bottom of the vehicle body.

[0056] The defrost and defog target refers to the defrost and defog impact angle requirement for the vehicle's front windshield. The impact angle can be within the range of 20-40 degrees. Preferably, the defrost and defog impact angle in this embodiment can be 30 degrees.

[0057] Vehicle configuration information refers to the functional configuration of the vehicle located in the dashboard, mainly including the head-up display, passenger airbag, air-conditioning box, dashboard pipe beam and defrost duct.

[0058] Step 102: Determine the layout data of the components in the instrument panel according to the human body and structure layout information and the vehicle configuration information;

[0059] In this embodiment, combined with Figure 2As shown, the layout data mainly reflects the layout of the components in the instrument panel, and the layout data mainly includes the main driver section data, the centerline section data and the co-driver section data. The layout positions of the head-up display, the co-driver airbag, the air conditioning box, the instrument panel tube beam and the defrost air duct can be obtained according to the human body and structure layout information and the vehicle configuration information; then, the main driver section data, the centerline section data and the co-driver section data are drawn according to the layout positions of the head-up display, the co-driver airbag, the air conditioning box, the instrument panel tube beam and the defrost air duct.

[0060] by Figure 2 For example, Figure 2 The image on the left refers to the midline section data at y=0. Figure 2 The image in the middle is the main section data of y=R. Figure 2 The image on the right is the co-pilot cross-sectional data with y=-R. The positive direction of the y-axis refers to the direction from the driver's seat to the co-pilot's seat. y=0 is roughly in the middle of the driver's seat and the co-pilot's seat. The cross-sectional data refers to the data of a certain section of the instrument panel.

[0061] Step 103: determining a limiting surface of the end surface of the instrument panel according to the layout data, the visibility target, the space target and the defrosting and defogging target;

[0062] In this embodiment, the end surface of the instrument panel mainly includes a front end surface, a rear end surface, an upper end surface and a lower end surface. Among them, the front end surface refers to the end of the instrument panel close to the front windshield. The rear end surface is opposite to the front end surface and refers to the end of the instrument panel close to the driver. The upper end surface refers to the end of the instrument panel facing the roof of the vehicle. The lower end surface is opposite to the upper end surface and refers to the end of the instrument panel facing the bottom of the vehicle.

[0063] Before designing the instrument panel, it is necessary to determine the limiting surface of each end face. The specific steps may include:

[0064] Combination Figure 3 As shown, according to the defrosting and defogging target, the position of the front windshield and the layout data, the limiting surface of the front face of the instrument panel is determined; here, the layout data specifically refers to the midline section data. The defrosting and defogging target involves the layout of the air conditioning outlet at the front windshield.

[0065] According to the visibility target and the layout data, the limiting surface of the upper end surface of the instrument panel is determined; here, the layout data refers to the centerline section data and the main driver section data. The visibility target refers to the need to meet the main driver's downward field of vision when designing the instrument panel. The downward field of vision is the driver's ability to observe the road, environment and vehicle conditions through the specific area below the front windshield of the vehicle or around the vehicle body during driving. Combined with Figure 4 As mentioned above, the lower field of view of this embodiment is generally greater than or equal to 5 degrees.

[0066] Combination Figure 5 As shown, according to the layout data and the foot space, the limiting surface of the lower end surface of the instrument panel is determined; here, the layout data refers to the main driving section data. The foot space is generally greater than or equal to 305mm. Based on the main driving section data and the foot space, the limiting surface of the lower end surface is determined.

[0067] The restriction surface of the rear end surface of the instrument panel is determined according to the knee space, the calf protection space, the hand reach and interface space and the layout data. Here, the layout data refers to the main driving section data. The knee space is generally greater than or equal to 70mm, and the calf protection space is generally greater than or equal to 100mm. The hand reach and interface space generally includes multiple space requirements, and different hand reach operations correspond to different space requirements.

[0068] After determining the limiting surface of each end face, it is equivalent to determining the envelope of the instrument panel. The design of the instrument panel boundary should not exceed the above limiting surface while considering the aesthetics.

[0069] 104: Designing the instrument panel according to the restriction surface of the end surface of the instrument panel and the vehicle assembly requirements.

[0070] In this embodiment, combined with Figure 6 As shown in the figure, the design of the dashboard also needs to consider the requirements for on-vehicle assembly. Because in the subsequent production and assembly of the designed dashboard, the robot needs to clamp the dashboard and enter the vehicle as a whole through the front door opening of the vehicle, and ensure that the safety gap is greater than 50mm. Therefore, the design size of the dashboard also needs to consider the requirements for on-vehicle assembly. In other words, after determining the limiting surfaces of each end face of the dashboard, it is necessary to further calculate the boundaries of the dashboard to ensure that the dashboard can meet the requirements for on-vehicle assembly.

[0071] That is to say, if the restriction surfaces of the end faces of the instrument panel meet the on-vehicle assembly requirements, the instrument panel is designed according to the restriction surfaces of the end faces of the instrument panel. If the restriction surfaces of the end faces of the instrument panel do not meet the on-vehicle assembly requirements, the step of determining the restriction surfaces of the end faces of the instrument panel according to the layout data, the field of vision target, the space target and the defrosting and defogging target is returned to execute, that is, the restriction surfaces of the end faces of the instrument panel are redetermined. In actual design, the restriction surfaces of the front end face of the instrument panel are mainly redetermined. Under the premise of considering the defrosting and defogging target, the position of the front windshield and the layout data, the restriction surface of the front end face of the instrument panel is moved backward to meet the on-vehicle assembly requirements. It is also possible to adjust the human body and structure layout information to meet the on-vehicle assembly requirements. For example, adjust the human body setting position, etc.

[0072] If the boundaries of the designed instrument panel are within the restricted surfaces of each end face and meet the requirements for vehicle assembly, CATIA can be used to draw new centerline section data, driver section data, and co-driver section data. Section data can quickly identify major problems in the concept development stage without design data, and provide reference direction for instrument panel modeling, reducing a lot of repeated verification work.

[0073] In summary, the embodiment of this specification provides a dashboard design method, which obtains the visual field target, space target, human body and structure layout information, defrosting and defogger target, and vehicle configuration information; determines the layout data of the components in the dashboard according to the human body and structure layout information and the vehicle configuration information; determines the limiting surface of the end face of the dashboard according to the layout data, the visual field target, the space target, and the defrosting and defogger target; designs the dashboard according to the limiting surface of the end face of the dashboard and the on-vehicle assembly requirements. Based on the target parametric design, the layout of the dashboard is optimized to avoid repeated modifications of the dashboard during the styling engineering stage, improve the efficiency of vehicle styling development and design, and shorten the product development cycle.

[0074] Furthermore, based on the method of this embodiment, according to actual development conditions, it is possible to promote the evolution strategy of the instrument panel of SUV / cross / sedan models equipped on the platform, and reduce the development cycle and cost of other types of models on the same platform.
