Description

Technical Field

[0001] This invention relates to the technical field of automotive interior design, specifically to an in-vehicle anti-slip mobile phone box and its quantitative design method, and a vehicle. Background Technology

[0002] With smartphones playing a central role in vehicle navigation, entertainment, and communication, and the development and application of in-vehicle wireless charging, in-vehicle phone holders have become a standard feature in modern car interiors, especially in the passenger side dashboard area. Their main function is to provide a stable and easily accessible storage location for mobile phones while the vehicle is in motion.

[0003] Currently, the design of in-vehicle phone boxes on the market largely relies on experience, and their main anti-slip measures focus on two aspects: 1. Material selection: Surface treatment with materials having a high static friction coefficient, such as TPE injection molding and imitation suede covering, is used to increase the friction between the phone and the supporting surface of the phone box.

[0004] 2. Structural Design: The phone box is designed with a certain tilt angle, using the component of gravity to help the phone rest against the back wall.

[0005] However, existing design methods have significant flaws: material selection and structural design (tilt angle) are often disconnected, lacking a systematic theoretical connection. Designers typically choose materials and tilt angles based on aesthetics (CMF) and general experience, which cannot adequately guarantee that the phone will not slip under extreme conditions such as emergency braking. If the anti-slip capability is insufficient, the phone may slip or even fly out during braking, interfering with the driver's attention or becoming a safety hazard; if the design is overdone (such as an excessively large tilt angle or a material with an excessively high coefficient of friction), it may sacrifice aesthetics, increase costs, or make it inconvenient to pick up and put down the phone.

[0006] Therefore, a scientific and quantitative design method is needed to lock in the anti-slip performance of the phone box as a calculable and verifiable target during the styling and engineering stages of vehicle development, thereby eliminating safety hazards at the source and achieving a balance between safety, aesthetics and practicality. Summary of the Invention This invention aims to at least solve one of the technical problems existing in the prior art. To this end, this invention provides a vehicle-mounted anti-slip mobile phone box and its quantitative design method, as well as a vehicle.

[0007] According to a first aspect of the present invention, a vehicle-mounted anti-slip mobile phone box includes: a support surface, the support surface being made of an anti-slip material, the support surface being inclined, and the support surface being used to support a mobile phone.

[0008] According to a second aspect of the present invention, a quantitative design method for a vehicle-mounted anti-slip mobile phone box is provided for designing the aforementioned vehicle-mounted anti-slip mobile phone box. The design method includes the following steps: The engineering team determined the vehicle's braking performance targets and defined the maximum braking deceleration limit 'a' for the vehicle. The design team has begun to design the appearance of the in-vehicle anti-slip phone box to generate preliminary design data. Based on the preliminary design data, the engineering team obtained the tilt angle α of the supporting surface and the static friction coefficient μ between the anti-slip material and the back cover of the phone. The engineering team verified the anti-slip performance of the vehicle-mounted anti-slip phone box based on the mechanical model. They substituted the maximum braking deceleration limit a, the tilt angle α, the static friction coefficient μ, and the gravitational acceleration g into formula K to determine whether formula K was valid. Formula K is: μ ≥ (a·cosα - g·sinα) / (g·cosα + a·sinα). The engineering team then fed the results back to the design team. If formula K is true, it means that the preliminary shape data meets the anti-slip requirements, and the styling team will lock in the preliminary shape data and enter the subsequent detailed design stage. If formula K is not true, it means that the preliminary design data does not meet the anti-slip requirements. The design team will modify the preliminary design data. After modifying the preliminary design data, the design team will repeat the above steps to check the anti-slip performance until the anti-slip performance meets the anti-slip requirements. Output the final design scheme of the in-vehicle anti-slip mobile phone box.

[0009] The quantitative design method for an in-vehicle anti-slip mobile phone box according to an embodiment of the present invention has at least the following beneficial effects: It can achieve precise pre-emptive and quantitative assurance of safety performance, break down the barriers between design and engineering, realize collaborative optimization, improve design efficiency and reduce costs, enhance the scientific nature and universality of design, and optimize user experience.

[0010] According to some embodiments of the present invention, the anti-slip material is determined based on the shape, color, and material definitions in the preliminary shape data.

[0011] According to some embodiments of the present invention, before modifying the initial styling data, the styling team further includes: The design team determined the direction of the modification, changing the key initial design parameters, tilt angle α and / or static friction coefficient μ.

[0012] According to some embodiments of the present invention, if the design team determines that the modification direction is to modify the tilt angle α, the engineering team substitutes the original anti-slip material and the static friction coefficient μ of the back cover of the phone into the formula K to deduce the new tilt angle α, and feeds the new tilt angle α back to the design team.

[0013] According to some embodiments of the present invention, if the modification direction determined by the styling team is to modify the static friction coefficient μ, the engineering team substitutes the original tilt angle α used into the formula K to deduce the new static friction coefficient μ, and feeds the new static friction coefficient μ back to the styling team.

[0014] According to some embodiments of the present invention, if the design team determines that the modification direction is to modify both the static friction coefficient μ and the tilt angle α simultaneously, the design team provides a new range of the tilt angle α and a variety of new anti-slip materials; the engineering team, based on formula K, the new range of the tilt angle α, and the static friction coefficient μ between the various new anti-slip materials and the back cover of the phone, combines to form multiple sets of key initial design parameters conforming to formula K, each set of key initial design parameters including the tilt angle α and the static friction coefficient μ, and feeds the key initial design parameter sets back to the design team.

[0015] According to some embodiments of the present invention, after the styling team receives feedback from the engineering team on the tilt angle α and / or the static friction coefficient μ, the styling team re-evaluates the impact of the combination of the anti-slip material corresponding to the tilt angle α and the static friction coefficient μ on the aesthetics and spatial sense of the design.

[0016] According to a third aspect of the present invention, a vehicle includes an in-vehicle anti-slip mobile phone box as described above, wherein the mobile phone storage box is disposed at the sub-dashboard and / or in front of the passenger seat.

[0017] According to some embodiments of the present invention, the vehicle-mounted anti-slip mobile phone box is disposed at the sub-dashboard.

[0022] In the description of this invention, "multiple" refers to two or more. The use of "first" and "second" is for distinguishing technical features only and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features or their sequential relationship.

[0023] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0024] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described below are some embodiments of the present invention, not all embodiments.

[0025] The technical solution of the present invention is as follows: A vehicle-mounted anti-slip phone box includes a support surface made of an anti-slip material, and the support surface is inclined relative to the horizontal direction to support the phone at an angle.

[0026] Specifically, in this embodiment, the in-vehicle anti-slip phone box is located on the passenger side of the vehicle's dashboard. In other embodiments, the in-vehicle anti-slip phone box can also be located in front of the passenger seat or behind the front seat. Those skilled in the art can choose the location of the in-vehicle anti-slip phone box according to actual needs.

[0027] A quantitative design method for an in-vehicle anti-slip mobile phone box includes the following steps: S100. Based on the vehicle development goals, the engineering team determined the overall vehicle braking performance targets. The engineering team defined the maximum braking deceleration limit 'a' (in m / s²) for the vehicle. The maximum braking deceleration limit 'a' serves as the input boundary condition for the design.

[0028] S200: The design team has initially designed the appearance of the in-vehicle anti-slip mobile phone box to form preliminary design data.

[0029] Based on preliminary styling data, the S300 engineering team obtained two key initial design parameters: the tilt angle α of the support surface and the static friction coefficient μ between the anti-slip material and the back cover of the phone. Specifically, the tilt angle α of the supporting surface and the static friction coefficient μ between the anti-slip material and the back cover of the phone are obtained as follows: The engineering team extracts the tilt angle α of the storage surface of the phone box from the CAS data of the sub-dashboard design (based on the horizontal plane); the engineering team determines the static friction coefficient μ of the material selected for the inner surface of the phone box according to the definition of the design, color and material (which can be obtained through standard testing of material samples).

[0030] S400: The engineering team verified the anti-slip performance of the in-vehicle anti-slip phone case based on a mechanical model. When the vehicle brakes at a deceleration of 'a', the phone is subjected to the combined effects of inertial force (downward along the slope), gravitational force, and static friction. To ensure the phone does not slip, the following anti-slip condition formula (Formula K) must be met: μ ≥ (a·cosα - g·sinα) / (g·cosα + a·sinα) Where g is the acceleration due to gravity (9.8 m / s²). The engineering team substituted the maximum braking deceleration limit a, the tilt angle α, the static friction coefficient μ, and the gravitational acceleration g into formula K to determine whether formula K is valid. Formula K is: μ ≥ (a·cosα - g·sinα) / (g·cosα + a·sinα). The engineering team then fed the results back to the styling team. Furthermore, the derivation of formula K is as follows: Imagine the mobile phone as a point mass of mass m, placed on an inclined plane with an angle of α. When the vehicle brakes with a deceleration a: The phone is subjected to a horizontal forward inertial force F = m·a; the component of the inertial force along the inclined plane is F1 = m·a·cosα; the resistance F2 that prevents the phone from sliding consists of two parts: the component of gravity along the inclined plane: G1 = m·g·sinα, and the maximum static friction force exerted by the inclined plane on the phone: fmax = μ·N, where the normal force N = m·g·cosα + m·a·sinα (generated by the components of gravity and inertial force perpendicular to the inclined plane). Therefore, F2 = m·g·sinα + μ·(m·g·cosα + m·a·sinα); To prevent the phone from swiping upwards, F1 ≤ F2, that is: m·a·cosα ≤ m·g·sinα + μ·(m·g·cosα + m·a·sinα) Simplifying the above inequality and eliminating the mass m, we obtain the formula K: μ ≥ (a·cosα - g·sinα) / (g·cosα + a·sinα).

[0031] S410. If formula K is true, it means that the preliminary shape data meets the anti-slip requirements. The styling team will lock the preliminary shape data and enter the subsequent detailed design stage. S420. If formula K is not true, it means that the preliminary design data does not meet the anti-slip requirements. The design team modifies the preliminary design data. Repeat the above steps S200-S400 until the anti-slip performance meets the anti-slip requirements.

[0032] The final design scheme for the S500 output vehicle-mounted anti-slip mobile phone box.

[0033] Before modifying the initial design data (i.e., before step S430), the design team also includes the following steps: S610, The styling team determined the direction of the modification, changing the key initial design parameters, tilt angle α and / or static friction coefficient μ.

[0034] S621. If the design team determines that the modification direction is to modify the tilt angle α, the engineering team substitutes the original anti-slip material and the static friction coefficient μ of the phone's back cover into the formula K to deduce the new tilt angle α, and feeds the new tilt angle α back to the design team.

[0035] S622. If the design team determines that the modification direction is to modify the static friction coefficient μ, the engineering team uses the original tilt angle α to substitute into the formula K, derives the new static friction coefficient μ, and feeds the new static friction coefficient μ back to the design team. The design team selects the material of the supporting surface based on the new static friction coefficient μ.

[0036] S623. If the design team determines that the modification direction is to modify both the static friction coefficient μ and the tilt angle α, the design team provides a new range of tilt angle α and a variety of new anti-slip materials. Based on formula K, the range of new tilt angle α, and the static friction coefficient μ between the various new anti-slip materials and the back cover of the phone, the engineering team combines multiple sets of key initial design parameters that conform to formula K. Each set of key initial design parameters includes tilt angle α and static friction coefficient μ, and the key initial design parameter sets are fed back to the design team.

[0037] In steps S621, S622, and S623, after the styling team receives feedback from the engineering team on the tilt angle α and / or static friction coefficient μ, the styling team re-evaluates the impact of the combination of the anti-slip material corresponding to the tilt angle α and static friction coefficient μ on the aesthetics and spatial sense of the design.

[0038] The vehicle includes the aforementioned in-vehicle anti-slip mobile phone box. Specifically, the vehicle can be a private car, such as a sedan, SUV, MPV, or pickup truck. The vehicle can also be a commercial vehicle, such as a van, bus, small truck, or large semi-trailer. The vehicle can be a gasoline-powered vehicle or a new energy vehicle. When the vehicle is a new energy vehicle, it can be a hybrid vehicle or a pure electric vehicle.

[0039] Taking an actual development process as an example, this method was applied to the design of the mobile phone box at the front of the secondary instrument panel in the development of an SUV model.

[0040] The development process is as follows: The design team created preliminary design data.

[0041] Based on the performance positioning of this vehicle model, its maximum braking deceleration target value is determined to be a = 0.8g (approximately 7.84 m / s²).

[0042] According to CAS data provided by the design department, the phone box design tilt angle α = 12°. The CMF solution suggests using a suede-like covering process, which, after testing, has a static friction coefficient μ = 0.52 with the phone's glass back cover.

[0043] Substitute a=7.84 m / s², g=9.8 m / s², α=12°, μ=0.52 into formula K for verification.

[0044] Calculate the right side of the inequality: (7.84*cos12° - 9.8*sin12°) / (9.8*cos12° + 7.84*sin12°) ≈ (7.67 - 2.04) / (9.59 + 1.63) ≈ 5.63 / 11.22 ≈ 0.50.

[0045] The engineering team determined that the inequality holds true for formula K: μ (0.52) ≥ 0.50.

[0046] The verification was successful. The design scheme (12° tilt angle, suede-like material) can meet the safety requirement of preventing the phone from slipping under 0.8g emergency braking of this vehicle model. The scheme was locked in and moved to the subsequent detailed structural design stage.

[0047] Comparative Example: If the initial design plan prefers to use a smoother PVC material (μ = 0.40) and maintain α = 12°.

[0048] Substituting the values ​​into the formula, the required value on the right is 0.50, while 0.40 < 0.50, so the verification fails.

[0049] At this point, the design team faced two choices: Option A (Change Material): Replace with a material with a higher coefficient of friction, such as the faux suede (μ=0.52) in this example.

[0050] Option B (Modified): Retain the PVC material, but according to the formula, the tilt angle α needs to be increased to approximately 16° or higher to meet the requirements. The team needs to assess the impact of increasing the tilt angle on the aesthetics and sense of space.

[0051] This method makes decision-making data-driven and transparent, facilitating rapid consensus among all parties.

[0052] The quantitative design method of the vehicle-mounted anti-slip mobile phone box in this solution establishes a mathematical model between vehicle braking acceleration, mobile phone box tilt angle and material static friction coefficient. The design scheme can be accurately verified and determined at the modeling data stage to ensure that the mobile phone does not slip under the specified braking conditions.

[0053] Compared with the prior art, the in-vehicle anti-slip mobile phone box design method provided by the present invention has the following significant advantages: 1. Achieving precise pre-emptive and quantitative assurance of safety performance: For the first time, vehicle braking dynamics and interior material mechanics are combined to establish a precise mathematical model. Quantitative verification can be performed during the styling and design stages, fundamentally ensuring the anti-slip effectiveness of the phone box under target braking conditions and eliminating potential safety hazards at the design source.

[0054] 2. Breaking down barriers between design and engineering to achieve collaborative optimization: This method provides a clear basis for dialogue and common design standards for the styling team (responsible for angle α and material μ) and the engineering team (responsible for braking target a). Within the framework of formula K, both parties can scientifically balance aesthetics, cost, and functional safety to find the optimal design solution and avoid major design changes later on.

[0055] 3. Improved design efficiency and reduced costs: Early, rapid calculations and iterations can avoid the high costs and time delays incurred by replacing materials or modifying molds later in the product development process due to unsatisfactory anti-slip tests. The first-time success rate of design solutions is significantly improved.

[0056] 4. Enhanced Scientific Rigor and Universality of Design: This method is derived from classical physics principles, possessing a solid scientific foundation and applicable to the design of mobile phone storage devices in any vehicle model and with any layout (sub-dashboard, center console, etc.). Universality verification can be completed simply by inputting the corresponding braking deceleration 'a', phone box tilt angle 'α', and static friction coefficient 'μ' of the phone box material.

[0057] 5. Optimize user experience: By precisely designing the tilt angle and materials within the safety boundaries, it is possible to avoid using excessively large tilt angles or overly rough materials in the name of "absolute safety," thereby ensuring the convenience of picking up and placing the phone and the comfort of operation, achieving the best balance between safety and user experience.
