Description

Technical Field

[0001] This utility model relates to the field of mobile device technology, and in particular to an accessible mobile phone charger and mobile phone. Background Technology

[0002] With the widespread use of smartphones, the elderly and visually impaired people are becoming increasingly reliant on mobile phone power, but existing charging devices do not take their physiological characteristics into account, resulting in significant obstacles to their use.

[0003] Positioning and alignment difficulties are the primary problems. With wired charging, the small plugs and ports (such as the Type-C plug, which is only 8.3mm wide) make it difficult for elderly people with mobility issues to align the device due to blurred vision or trembling hands. Blind people, in particular, rely on groping, which can easily damage the device and poses a risk of electric shock. Wireless charging pads require the phone to be precisely placed within a 5-8cm sensing area; misalignment results in disconnection. Elderly people with mobility issues cannot see the markings, and blind people cannot locate the device, leading to frequent adjustments without charging success. The lack of clear status feedback exacerbates user anxiety. Ordinary devices rely on icons on the phone screen or tiny LED lights to indicate status, which are difficult for elderly people with mobility issues to see and completely ineffective for blind people, often causing them to worry about whether the device is charging. A few devices with audible prompts have fixed volume and poor sound quality, making them difficult for elderly people with hearing loss to recognize.

[0004] In summary, existing devices have shortcomings in operation and feedback, causing elderly people with mobility difficulties and visual impairments to face problems such as "difficulty in positioning, complicated operation, and weak perception." There is an urgent need for a low-threshold, highly reliable charging solution designed specifically for them. Utility Model Content

[0005] Based on this, it is necessary to address the above-mentioned shortcomings by providing an accessible mobile phone charger, including a controller, an adapter, and a charging base. The adapter includes: a housing, a connector located on the top of the housing and matching the mobile phone charging port interface, and a first metal contact located on the bottom of the housing and electrically connected to the connector. The charging base includes: a base plate, a back plate, two side panels, a front baffle, and the controller. The base plate has a second metal contact corresponding to the first metal contact, and the second metal contact is electrically connected to the controller. The back plate, two side panels, and front baffle are arranged on the base plate around the second metal contact to form a mobile phone placement position. The surface of the back plate facing the placement position is an inclined surface that slopes away from the placement position.

[0006] Preferably, the connector is a Micro-USB connector, a Type-C connector, or a Lightning connector, or a combination of the above three connectors.

[0007] Preferably, the charging dock is also equipped with a speaker, which is electrically connected to the controller.

[0008] Preferably, the second metal contact is a metal spring.

[0009] Preferably, a pressure sensor is provided on the base plate, and the pressure sensor is electrically connected to the controller.

[0010] Preferably, the bottom surface of the charging dock is provided with double-sided adhesive.

[0011] A mobile phone is also provided, which includes any of the above-mentioned accessible mobile phone chargers.

[0012] Preferably, the adapter is integrated inside the mobile phone and electrically connected to the charging circuit of the mobile phone.

[0013] The aforementioned accessible charger and mobile phone, through the setting of a mobile phone placement position formed by an inclined back panel, side panels, and front baffle, utilize gravity and structural guidance to achieve automatic mobile phone positioning, eliminating the need for manual alignment. This significantly reduces the operational difficulty caused by blurred vision, hand tremors, or lack of sight, and avoids situations where repeated adjustments fail to connect the mobile phone charger. At the same time, once the adapter is connected to the mobile phone charging port, it can be used for a long time. Subsequent charging is completed through metal contact, reducing the damage to the device caused by traditional plugging and unplugging methods, improving ease of use and device lifespan, and effectively improving the charging experience for people with mobility impairments and visual impairments.

Detailed Implementation

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] This utility model discloses an accessible mobile phone charger, such as... Figures 1-4 As shown, the device includes a converter and a charging dock. The converter has a connector on the top of its housing that matches the phone's charging port, and a first metal contact on the bottom of its housing. The connector and the first metal contact are electrically connected inside the converter via wires. The upper surface of the converter is flush with the bottom of the phone. The charging dock includes a base plate, a back plate, two side panels, a front baffle, and a controller. The base plate has a second metal contact corresponding to the first metal contact. The second metal contact is electrically connected to the controller located inside the charging dock. The controller is electrically connected to an external power source and controls the input of the external power source. The back plate, two side panels, and front baffle are arranged around the second metal contact on the base plate to form a phone placement position. The surface of the back plate of the phone placement position is a slope. This slope causes the phone to tilt backward when placed in the phone placement position, and causes the overall center of gravity of the phone and its charger to move backward and be located near the back plate of the phone placement position, making the whole device more stable.

[0018] The barrier-free mobile phone charger provided by this utility model has the following usage process: 1. Pre-connection stage: Insert the connector on the top of the adapter into the mobile phone charging port, so that the mobile phone and the adapter form a whole; 2. Placement stage: Place the mobile phone with the adapter into the mobile phone placement position of the charging base. At this time, the first metal contact at the bottom of the adapter will make precise contact with the second metal contact on the base plate; 3. Power supply stage: The controller of the charging base connects to the external power supply to supply power to the second metal contact. Current is transmitted to the mobile phone through the path of second metal contact → first metal contact → internal circuit of adapter → mobile phone charging port to complete charging; 4. Charging end: After charging is completed, simply take out the mobile phone without removing the adapter, which is convenient for the next charging.

[0019] This utility model provides a barrier-free mobile phone charger that simplifies the charging process and reduces the difficulty of the action. Traditional charging requires "holding the data cable plug → aligning it with the phone's charging port → forcefully inserting it," a process that relies on fine hand coordination and visual assistance, which is extremely unfriendly to people with mobility impairments (such as shaky hands or weak fingers) and visual impairments. Users of this barrier-free mobile phone charger only need to: ① insert the adapter connector into the phone for the first time (this can be done with assistance from someone else, eliminating the need for repeated operations); ② for subsequent charging, simply place the phone in the charging slot, without needing to align it with the plug, reducing the need for fine motor skills by more than 90%. Furthermore, this charger features automatic positioning, reducing the user's alignment burden. The phone placement area is formed by a tilted back panel, side panels, and a front baffle, providing "guided positioning." The tilted back panel uses gravity to naturally conform the phone to the surface, eliminating the need for manual angle adjustment; the side panels limit lateral movement, and the front baffle prevents the phone from sliding forward. These three elements work together to ensure that the first metal contact of the adapter automatically aligns with the second metal contact of the base plate after the phone is placed in, preventing charging failure due to inaccurate positioning. This is especially beneficial for visually impaired users (who cannot clearly see the contact points). In addition, this charger reduces plugging and unplugging damage and extends device lifespan. Traditional chargers, with repeated plugging and unplugging of the phone's charging port, can easily lead to loosening and damage (especially for those with mobility issues, as uneven force may be applied during plugging and unplugging). In this design, the adapter connector only needs to be inserted once (remaining on the phone for extended periods), and power is supplied through contact points during charging, virtually eliminating wear and tear on the phone's interface from plugging and unplugging.

[0020] In one embodiment, the connector is a Micro-USB connector, a Type-C connector, a Lightning connector, or a combination of all three. These three connectors are the three mainstream connectors used in mobile phones on the market. Among them, the Micro-USB connector is commonly found in some older Android phones and low-end smart devices (such as feature phones for seniors). Considering that some elderly people often have frugal lifestyles and use inexpensive and older devices, the use of a Micro-USB connector is essential. If the adapter only supports a single interface (such as Type-C only), users of iPhones (Lightning) or older Android phones (Micro-USB) cannot use the accessible charger, resulting in a narrow range of product applications. However, by supporting three mainstream interfaces, it can cover almost 99% of smartphone users worldwide (especially including older models commonly used by the elderly and those with mobility impairments), allowing users of different devices to enjoy the convenience of accessible charging. The core of accessible design is to "reduce the user's operational and decision-making burden." For users with visual impairments or cognitive impairments (such as Alzheimer's disease), the complex "interface matching" judgment itself is a burden. By providing adapters with three mainstream interfaces, users or their caregivers can directly select the adapter based on their phone model, without needing to understand interface technology differences, thus simplifying product selection and usage. Furthermore, in group settings such as nursing homes and rehabilitation centers, multiple brands and models of mobile phones are often present. Multi-interface chargers can meet the needs of multiple people in the same space, eliminating the need for multiple dedicated chargers for different devices and reducing the institution's procurement and management costs.

[0021] In one embodiment, the charging dock also includes a speaker, which is electrically connected to the controller. This allows the charging dock to transmit charging status information to the user via sound signals. The controller monitors the following charging processes in real time: whether charging has started, charging is complete, poor contact, power failure, etc. When a preset state is triggered (such as charging start, fully charged, fault), the controller sends an electrical signal to the speaker. The speaker converts the electrical signal into sound (such as a prompt tone or voice broadcast) to convey the charging status information to the user. The barrier-free charger provided by this utility model is equipped with a speaker that can replace visual feedback, making it suitable for visually impaired people. When charging traditionally, users need to check whether the phone screen is lit or whether a charging icon is displayed to determine the charging status. However, visually impaired people (such as blind people or people with low vision) cannot rely on vision to obtain information and often repeatedly adjust their phones due to uncertainty about whether they are charging, which is a significant burden. The speaker can provide direct sound feedback: when the phone is placed in the charging dock and successfully connected, a "charging started" prompt tone is played; when charging is complete, a "charging complete" prompt tone is played; when there is poor contact (not charging), a "please adjust phone position" prompt tone is played. This allows visually impaired individuals to clearly understand the charging status solely through hearing, without needing to visually engage, thus reducing operational anxiety. Furthermore, conveying status information through sound simplifies information retrieval and reduces cognitive burden. For individuals with cognitive impairments (such as Alzheimer's patients) or limited mobility (such as bedridden elderly), viewing a phone screen requires a series of complex and easily forgotten actions. The speaker's sound feedback is direct and immediate: a notification sound is emitted as soon as the phone is placed, eliminating the need for active phone operation. It delivers key information in the simplest way, reducing the demands on the user's memory and operational abilities, significantly lessening the burden of use.

[0022] In one embodiment, such as Figure 2 , Figure 3 As shown, the second metal contact is a metal spring, which optimizes the stability and fault tolerance of the contact through an elastic structure, further adapting to the problem of insufficient operational precision in accessible scenarios. The metal spring is a conductive metal component with elastic deformation capability. Its cooperation logic with the first metal contact is as follows: when the mobile phone connected to the adapter is placed in the charging dock, the first metal contact on the bottom of the adapter will contact the second metal contact (metal spring) on ​​the base plate; the metal spring undergoes elastic deformation due to pressure, generating an upward reaction force, making the metal spring and the first metal contact fit tightly; even if the mobile phone is slightly misaligned, the elasticity of the spring can still ensure that the two continue to contact, ensuring circuit conduction and improving the fault tolerance of the device.

[0023] In one embodiment, a pressure sensor is provided on the base plate. The pressure sensor is electrically connected to the controller and detects the placement status of the mobile phone through pressure signals, enabling more intelligent charging control and interactive feedback, further enhancing the practicality of the accessibility design. When a user places a mobile phone connected to the adapter into the placement position of the charging dock, the weight of the mobile phone and the adapter will press against the pressure sensor on the base plate, causing it to detect a change in pressure value. The pressure sensor converts the pressure signal into an electrical signal and transmits it to the controller. The controller determines whether the pressure signal has reached the "effective placement" threshold (e.g., the pressure value is stable within a certain range and lasts for a certain period of time, excluding accidental touches) through a preset program, and then triggers the corresponding operation (e.g., starting charging, activating the prompt function, etc.). When the mobile phone is removed, the pressure sensor detects the disappearance of pressure, and the controller can trigger operations such as stopping charging and turning off the accessibility function. Chargers without pressure sensors require the user to ensure that the metal contacts of the adapter and the charging dock are in full contact for charging to begin. However, people with mobility impairments or visual impairments may not be able to determine whether the mobile phone is placed correctly due to insufficient operational precision. The addition of a pressure sensor automates the charging process: as long as the phone is stably placed in the charging slot and the pressure reaches the threshold, the controller automatically activates the charging circuit without requiring additional user confirmation or operation; after the phone is removed, the pressure disappears, and the controller automatically cuts off the charging output or enters standby mode. This effectively improves the product's convenience and user-friendliness.

[0024] In one embodiment, such as Figure 4 As shown, the charging stand has double-sided adhesive on the bottom, which secures it to flat surfaces such as desktops and bedside tables, limiting its movement during use. In this embodiment, the double-sided adhesive is removable, providing stable adhesion and allowing for easy repositioning as needed, while avoiding residual damage to the surface. For users with mobility impairments or visual impairments, a slippery charging stand increases the difficulty of aligning the phone. Once secured with double-sided adhesive, the charging stand is stable, eliminating the need for users to adjust its position; they can focus solely on placing the phone, lowering the barrier to entry and aligning with the core goals of accessibility design.

[0025] In one embodiment, the first metal contact point in the adapter is integrated into the mobile phone and is electrically connected to the charging circuit of the mobile phone, reducing the "pre-connection" step and further simplifying the charging operation.

[0026] The aforementioned accessible mobile phone charger features a phone placement area enclosed by a tilted back panel, side panels, and a front panel. It utilizes gravity and structural guidance to automatically position the phone, eliminating the need for manual alignment. This significantly reduces operational difficulties caused by blurred vision, hand tremors, or visual impairment, and avoids situations where repeated adjustments fail to connect the charger. Furthermore, once the adapter is connected to the phone's charging port, it can be used continuously. Subsequent charging is completed via metal contacts, reducing damage to the device caused by traditional plugging and unplugging methods. This improves ease of use and device lifespan, effectively enhancing the charging experience for people with mobility impairments and visual impairments.

[0027] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
