Automobile design is an important means of competition to promote automobile sales. Large companies will use the means of frequent replacement of vehicles to gain consumers' favor and win over competitors. Automotive design is the first step in automotive development and has become increasingly important throughout the automotive design process.
New product development refers to a series of decision-making processes from the research and selection of products that meet the needs of the market, to product design, process manufacturing design, and to normal production. According to different development depths, new product development is also divided into four levels, S1 level development is the simplest, and S4 level involves the most comprehensive development content.
Level classification of automotive new product development depth
According to different development methods, product development can be divided into two main ways: reverse development and forward development. Reverse development began with prototype car benchmarking, which was derived from passive imitation of prototype products. Forward development begins with the early product planning, which stems from the initiative to develop a product.
Reverse development has low investment, low cost, and short development cycle. It is suitable for the initial development stage and solves the problem of product availability. At present, most of the low-speed electric vehicle companies adopt imitation roads, and then develop S1-level deep series products based on the reverse developed platform models. For example, the most common types of Benben models on the market are variants of front and rear bumpers, lights, or interior modifications based on the Benben platform models.
Forward development is an inevitable trend in the future development of low-speed electric vehicles, and it is impossible to rely solely on individual strengths. To a large extent, it depends on the scientific organization procedures for developing design and its standardization. This week's weekly report will outline the styling process for the development of the model and the content of the relevant links.
The data-based product modeling forward development flow chart is as follows:
The development of new vehicles must first conduct product feasibility analysis and product research on target markets. The main tasks are as follows:
(1) Research on consumer groups: including lifestyles, hobbies, values, consumption views, outlook on life, and use of vehicles.
(2) Competing product analysis and positioning: Identify the design direction and positioning by analyzing existing products of the same type and other companies that may form a competitive relationship in the future.
(3) Product positioning: Through the pre-design survey, determine the use and aesthetic needs of the target user population, as well as functional positioning.
(4) Determination of modeling style: The person in charge of product design convene relevant designers to discuss and determine the style, image and design direction of the product.
(5) Formulate preliminary technical plan: Calculate the technical specifications and expected performance parameters of selected models, and analyze whether the technical process can adapt to the technical level and process capability of the enterprise.
(6) Financial analysis: Analyze factors such as cost control to predict whether products can bring profits to enterprises.
2. Total layout designThe general layout design is the basis of the design. The total layout design determines the main size and basic shape of the vehicle, and stipulates the design hard points for the designer's conception and play, so that the shape and creative design can be targeted.
The overall layout design determines the configuration relationship, weight, regulations and performance indicators of the vehicle, chassis, powertrain and other systems through the overall planning of the vehicle design. Most of the current layout designs use digital three-dimensional design. Low-speed electric vehicle companies can make appropriate changes and partial improvements based on the existing mature overall layout, which can simplify the workload and shorten the development cycle.
12V
Dc Motor Can drive under the rated voltage 12 v dc motor, most of the products our company can achieve the 12 v voltage drive, speed can be customized according to customer demand.
Characteristics: 12V dc
motor With torque, low noise, small size, light weight, easy to use, constant speed operation, etc, also can match all kinds of reducer in order to achieve the purpose of changing the output speed and torque
Application field: 12V Dc Motor part of the armature iron core, armature, commutator and other devices, dc motor is suitable for most of the electronic products, such as electric toothbrush, razor, medical apparatus and instruments, breeze machine, mixer, etc
Method of use: the best stable in horizontal plane, installed on the 12V dc motor output shaft parts, cannot use a hammer to knock, knock prone to press into the 12V dc motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
12V dc motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a 12V dc motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
12V dc motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of geared motors is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry. Welcome to our factory.
