Description

Technical Field

[0001] The present invention relates to the technical field of automobile accessory design, and in particular to a design method for an automobile central armrest box, an automobile central armrest box and an automobile. Background Art

[0002] A car armrest is a storage space installed between the front seats, typically located centrally between the driver and front passenger seats. Armrests offer a wide range of storage functions, typically featuring a flip-up lid that opens to reveal a spacious compartment suitable for storing a variety of small items, such as wallets, phones, keys, snacks, and documents. The interior is often equipped with small dividers or zippered pockets for easy organization and convenience.

[0003] Furthermore, car armrests provide a comfortable support point. During extended driving or riding, drivers and passengers require a comfortable support point to alleviate arm and shoulder fatigue. Armrests are designed to provide this support point, allowing the arms to rest comfortably, significantly enhancing comfort. This support is particularly evident at high speeds or on bumpy roads, effectively reducing body movement.

[0004] In summary, as a practical in-car configuration, the car armrest box has rich storage functions, provides comfortable support, and has certain safety and auxiliary functions. It can not only improve the comfort of the driver and passengers, but also help organize clutter in the car and improve space utilization.

[0005] The existing design process of automobile armrest boxes usually requires optimization through multiple design iterations and physical verification according to different vehicle models to ensure the comfort of the automobile armrest box. There is no standardized design method for the position of automobile armrest boxes, which not only leads to a long design cycle of automobile armrest boxes, but also increases the cost of sample trial production.

[0027] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0028] The purpose of the present invention is to provide a design method for a car center armrest box, a car center armrest box and a car, so as to solve the problems existing in the prior art, provide accurate and comprehensive data support for the layout of the center armrest box, so that the design of the center armrest box meets the requirements, helps the driver maintain a correct posture, effectively supports the driver's elbows, and improves driving comfort.

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] Example 1:

[0031] like Figures 1 to 4 As shown, this embodiment provides a design method for a central armrest box 2 of a car, comprising the following steps: obtaining the position of the dummy's H-point 1, which is the dummy's hip point and is equivalent to the design reference point; when a standard dummy sits on a seat (here, the driver's seat is selected) in a standard sitting posture, we can obtain the H-point. Determine the distance from the front end of the central armrest box 2 to the dummy's H-point 1 in the car's length direction; the central armrest box 2 usually has a box body and a top cover snapped onto the box body, with the front end of the top cover being closer to the front end of the box body, or the front end of the top cover being flush with the front end of the box body, to ensure that the driver's elbow is supported by a larger area of the top cover. Determine the distance from the rear end of the central armrest box 2 to the dummy's H-point 1 in the car's length direction. The rear end of the central armrest box can be the rear end of the top cover or the rear end of the box body. Determine the distance from the top end of the central armrest box 2 to the dummy's H-point 1 in the car's height direction. Determine the angle between the elbow support surface of the central armrest box 2 and the horizontal plane to ensure that the driver's elbow can be supported more comfortably. Determine the width of the central console box 2; determine the distance between the central console box centerline 3 (this centerline is parallel to the vehicle length direction) and the dummy H point 1 in the vehicle width direction.

[0032] Therefore, this embodiment can provide accurate and comprehensive data support for the layout of the central armrest box by determining the distances between the front end, rear end, top end, center line of the central armrest box and the dummy's H point 1, and determining the angle between the elbow support surface on the central armrest box and the horizontal plane, and the width of the central armrest box, so that the design of the central armrest box 2 meets the requirements, helps the driver maintain a correct posture, effectively supports the driver's elbows, and improves driving comfort; this design data can also be used to verify the actual dimensions, reduce repeated trial and error rectification in the actual stage, and shorten the project verification cycle and development costs.

[0033] In this embodiment, the distance from the front end of the central armrest box 2 to the H-point 1 of the dummy in the length direction of the vehicle is 80mm~175mm; in this embodiment, the distance from the rear end of the central armrest box 2 to the H-point 1 of the dummy in the length direction of the vehicle is not less than 90mm, ensuring that the central armrest box has a larger length dimension in the length direction of the vehicle and can support the elbows of drivers with different forearm lengths.

[0034] In this embodiment, the distance from the top of the central armrest box 2 to the dummy's H point 1 in the vehicle height direction is 170 mm to 190 mm, which meets the elbow support height of most drivers.

[0035] In this embodiment, the elbow support surface of the center console box 2 is a flat surface, with the rear end of the elbow support surface intersecting with the top of the center console box 2. In this embodiment, the elbow support surface of the center console box 2 is at an angle of 0 to 10 degrees with the horizontal plane, improving the comfort of the driver's elbow support.

[0036] In this embodiment, the width of the central armrest box 2 is not less than 140 mm, ensuring that the central armrest box 2 has a large support width.

[0037] In this embodiment, the distance between the center line 3 of the central armrest box and the H point 1 of the dummy in the width direction of the car is 350 mm to 380 mm, ensuring that the position of the central armrest box 2 is compatible with the elbow position of most drivers.

[0038] The aforementioned dimensional constraints determine the installation area and overall dimensions of the center armrest box 2, meeting human-machine comfort requirements. Furthermore, by optimizing the comfort design position of the center armrest box 2, a corresponding reference is provided for subsequent project data development and design phases. The finished center armrest box may have a more detailed design shape and dimensions, and the dimensions of the assembled center armrest box from its various components may differ from the aforementioned design dimensions. These design dimensions can also be used to verify the dimensions of the finished center armrest box 2.
