Description

Technical Field

[0001] This utility model relates to the field of charging applications, and in particular to an auxiliary structure for a charging head without a support body. Background Technology

[0002] Analysis of the pain points of using plugs and sockets for charging in public places: Inappropriate height and location: In public places, sockets are often designed on walls or pillars more than 1.5 meters above the ground, such as next to self-service machines in hospitals or inside electrical boxes in shopping malls. This design forces users to tiptoe or hold up their devices while charging, causing inconvenience. This design ignores basic ergonomic principles, especially for children, wheelchair users, and other special groups, making it extremely unfriendly and increasing the difficulty of use for them. Cable length constraints: Ordinary charging cables are mostly less than 1 meter long. When facing high-positioned sockets, users often need to hold their phones to shoulder height to maintain a connection. Furthermore, some public places use hanging flexible sockets, but after the cable hangs down naturally, the effective usable length is only 40-60 centimeters, which is insufficient to meet the charging needs of users in a normal posture.

[0003] Safety Hazards of Device Placement: Temporary Placement Risks: In the absence of dedicated storage platforms, users are forced to place their phones on windowsills, on top of trash cans, or other non-dedicated areas, increasing the risk of the device slipping and breaking. Monitoring data shows that 23% of phone screen breakage incidents occur while charging in public places. Hand Fatigue and Safety Hazards: Continuously holding a charging device can cause an average of 30° wrist strain every 15 minutes. In scenarios such as transportation hubs, users are easily distracted by their devices and neglect their belongings. Surveillance data from a shopping mall shows that the probability of luggage loss increases by 47% when charging while holding the device.

[0004] An urgent need in medical settings: In hospital settings, patients often need to charge their devices while operating the registration system, but high-positioned sockets force them to operate the interface with one hand, severely impacting efficiency. A survey by a top-tier hospital showed that 63% of patients chose to forgo on-site charging due to this issue.

[0005] Hygiene concerns in entertainment venues: Wall sockets next to tables can easily allow charging cables to come into contact with food residue. A testing agency sampled 20 restaurants and found that the total number of bacteria on the charging cables was 3.6 times higher than that on toilet seats, posing a significant hygiene hazard.

[0006] Improvement schemes for existing technologies:

[0007] Human-centered facility renovation: Drawing on the experience of the Xiamen Administrative Service Center, we installed sloping charging stations with USB ports, integrating cable storage and equipment brackets to facilitate user charging while maintaining equipment stability.

[0008] Technology upgrade application: Explore wireless charging devices that comply with the Qi standard to eliminate cable length limitations, giving users more freedom when charging and freeing them from the constraints of cable length.

[0009] Safety standards have been established: Standards for the installation height of charging equipment in public places have been set, with a recommended range of 60-110 cm from the ground. Currently, some commercial complexes are piloting "charging island" solutions, lowering the socket height to 80 cm and equipping them with silicone anti-slip mats to improve user charging safety and convenience.

[0010] However, not all public places are in a position to implement these improvements.

[0011] On May 6, 2025, using "support and clamping and charging head and mobile phone and placement" as the abstract keywords and selecting "allow synonym expansion", a search was conducted in the China Patent Publication Database, and the following irrelevant literature was found: CN220155900U, published on December 8, 2023, relates to a multi-functional charging head and belongs to the field of charging head technology. A multi-functional charging head includes a charging head body, a data cable, a winding assembly, and a support assembly. The USB end of the data cable is inserted into a USB slot on the charging head body. The winding assembly is used to store and limit the data cable.

This invention, by setting up the winding assembly, can wind the data cable around the two winding rollers and clamp and limit its position when storing it. This not only prevents the data cable from tangling and knotting but also prevents it from falling off the winding rollers. During the charging process, when the data cable is long, a portion of it can be stored according to usage needs, thus preventing the data cable from appearing messy.

[0012] CN115219742A, published on October 21, 2022, discloses a charging head fixing and placement device for mobile phone charger production and processing, belonging to the technical field of mobile phone production equipment.
