AMPS The size standards for hole positions are mainly based on industry practice、Comprehensive determination of compatibility requirements and technical specifications，Specifically involving the following aspects：

one、The combination of industry standards and market practices

AMPS The size standard of the hole position is not determined by a single international standard organization（as ISO、SAE）Unified formulation，But gradually formed through market demand and industry consensus。for example，In the field of car mounts 30×38mm The hole position is widely used，Mainly for compatibility 1 Inches or1.5/2.25 Connection requirements for inch ball head，Ensure that brackets and equipment from different brands can be interchanged for use。The popularity of this size originated from car mounted vehicles、The demand for standardized interfaces in shipborne equipment，Avoid installation issues caused by incompatible sizes。

In the field of consumer electronics，AMPS The standards for hole positions are more dominated by manufacturers。for example，Sony PS5 of Access Three are reserved at the bottom of the controller AMPS Screw hole position，The size and position design should take into account ergonomics（If it is convenient to fix on the bracket）And manufacturing process（Feasibility of Injection Molding）。These standards are usually determined through negotiation between manufacturers and third-party accessory suppliers，To ensure the compatibility of the product ecosystem。

two、Drivers for compatibility and interchangeability

AMPS The size design of the hole position needs to consider compatibility with existing hardware。for example，30×38mm The hole spacing and common 1 Inch ball head base matching，But 10-24 or 1/4-20 Thread specifications are compatible with universal screws。This design logic is similar to USB Standardization of interfaces —— By unifying physical dimensions and connection methods，Lowering the user's threshold for use。

Besides，AMPS The hole position “modularization” Characteristics also drive the formation of standards。for example，The car mount needs to be compatible with tablets or navigation devices of different sizes，The size of the hole should take into account both the weight of the equipment and the stability of installation。Manufacturers will refer to the parameters of mainstream products in the market when designing，Establish default industry standards。

three、Manufacturing process and material limitations

The determination of hole size requires consideration of material strength and processing feasibility。for example，30×38mm The hole spacing is easy to achieve in injection molding or metal processing，Simultaneously capable of withstanding the weight and vibration of the equipment。If the hole spacing is too small，May cause material stress concentration；If it is too large，It will increase the volume of the bracket。Besides，The thread specification needs to match the strength of the screw，Avoid connection failure caused by thin threads。

In the field of consumer electronics，AMPS The design of hole positions also needs to consider lightweight requirements。for example，PS5 Access The holes of the controller are made of lightweight materials（as ABS plastic），Simultaneously optimizing the structure（Such as reinforcement design）Ensure fixed strength。

four、User needs and scenario adaptation

AMPS The size of the hole position needs to meet the specific usage requirements of the scene。for example，PS5 Access The hole position of the controller should be convenient for disabled players to fix on wheelchairs or tabletops，The hole position of the car mount needs to adapt to the stability of the vehicle in bumpy environments。Manufacturers usually optimize hole design through user testing and feedback，for example：

• Ergonomic validation：Test the impact of different hole positions on operational convenience。

• Environmental adaptability testing：Simulate vibration、The Influence of Temperature Changes on Hole Connection。

five、Typical Case：Differences in standards between automotive and consumer electronics fields

1. car mount：
   30×38mm Hole position is the mainstream choice，Main adaptation 1 Inch ball head，Its standards may have been referenced SAE J1455 Waiting for vehicle environment testing standards。for example，Dell's car dock passes through SAE J1455 crash test，Ensure the reliability of the hole position under vehicle vibration。

2. Consumer electronic devices：
   More flexible hole size and thread specifications。for example，PS5 Access The controller adopts 10-24 and 1/4-20 Mixed pore position，Compatible with both universal tripods，Also supported AMPS Standard fixed plate。This type of design is more defined independently by manufacturers based on product positioning and user needs。

summary

AMPS The size standard for the hole position ismarket demand、Industry Collaboration、The combined effect of manufacturing process and user feedbackthe result：

• Vehicle field：30×38mm The default standard for hole positions is formed through market practice，Balancing compatibility and environmental adaptability。

• consumer electronics：Manufacturer led hole design，Emphasize lightweight design、Usability and ecological compatibility。

• core logic：Through a unified physical interface，Reduce user usage costs，Simultaneously meet the performance requirements of specific scenarios。

Despite the lack of a single international standard，but AMPS The hole position has become a vehicle mounted device、The factual standards in fields such as consumer electronics，The determination of its size reflects “Practical priority、Gradually iterating” Industry characteristics。
