Description

Technical Field

[0001] This utility model belongs to the field of gaming equipment technology, specifically relating to a mobile game controller component that is compatible with multiple devices, has a stable connection, and supports placement at multiple angles. Background Technology

[0002] With the widespread adoption of mobile games, mobile game controllers, as essential accessories for enhancing the gaming experience, have become a core concern for users in terms of compatibility and connection stability. Currently, mobile game controllers are mainly divided into two categories:

[0003] One type is the controller that connects to the phone via a wired TYPE-C interface, such as the Chinese patent announcement number CN307594692S, entitled "Mobile Game Controller (YW03)". Its interface position (height) is fixed, resulting in extremely poor compatibility: for thinner phones, the interface connection end is prone to being suspended in the air, causing the phone to be placed unbalanced; for thicker phones, it is even impossible to fit into the predetermined clamping position; moreover, the phone is fixed in a single direction, and it is impossible to adjust the horizontal or vertical placement according to the game scene, let alone adapt to other devices such as tablets and desktop computers.

[0004] Another type is the controller that connects wirelessly to a mobile phone via Bluetooth module. For example, the Chinese patent announcement number CN305362567S, named "Bluetooth Game Controller (CZ-F16)," has solved the compatibility problem of wired connection, but it has an insurmountable signal delay defect. Especially in competitive games, millisecond-level delay can seriously affect the accuracy of operation and reduce the gaming experience.

[0005] Therefore, designing a mobile game controller component that is compatible with devices of different thicknesses, supports multi-directional placement, achieves low-latency connection, and can be expanded to be used on multiple devices has become an urgent problem to be solved by those skilled in the art. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of existing mobile game controllers, such as poor compatibility, connection delay, or limited usage scenarios, and to provide a mobile game controller component that uses 2.4G wireless transmission technology combined with a detachable receiver design to achieve low-latency connection, multi-device compatibility, and multi-directional placement, thereby improving the gaming experience and usage flexibility.

[0007] The above-mentioned objective of this utility model is achieved through the following technical solution: a mobile game controller assembly, including a controller part and a 2.4G wireless receiver, wherein the controller part has a circuit board inside, and a 2.4G wireless transceiver chip is integrated on the circuit board; the 2.4G wireless receiver and the 2.4G wireless transceiver chip establish a wireless communication connection through the 2.4G frequency band to realize data transmission.

[0008] Furthermore, the 2.4G wireless receiver has a flat structure with a thickness of 3-10mm (the thickness does not include the length of the USB male connector).

[0009] Furthermore, the internal structure of the 2.4G wireless receiver includes:

[0010] The receiving main control chip: adopts a low-power 2.4G wireless receiver chip (such as the NRF24L01 series), which is responsible for receiving the wireless signals transmitted by the handle and converting the signals into standardized digital command data;

[0011] The USB protocol chip is electrically connected to the USB male connector and is used to convert the digital command data output by the main control chip into signals that conform to the USB communication protocol, ensuring that external devices (mobile phones, computers, etc.) can recognize and respond to it.

[0012] Connection relationship: The receiving master control chip and the USB protocol chip are bidirectionally electrically connected through SPI (Serial Peripheral Interface) or I2C (Integrated Circuit Bus). The receiving master control chip transmits the processed digital instruction data to the USB protocol chip through the above interface. At the same time, the USB protocol chip can feed back the device connection status signal to the receiving master control chip through the interface.

[0013] The power supply module obtains 5V DC power from an external device via a USB male connector, and after voltage regulation, provides stable operating voltages for the receiving main control chip and the USB protocol chip respectively.

[0014] The shielding cover encloses the receiving main control chip and the USB protocol chip, reducing external electromagnetic interference and improving the stability of wireless reception and data transmission.

[0015] The outer shell is made of ABS plastic injection molding, with reserved mounting slots for components inside. The above components are encapsulated into a flat whole, and the surface of the outer shell is treated with anti-slip texture to facilitate insertion and removal.

[0016] Furthermore, the handle portion is provided with a mobile phone clamp for fixing the device. The inner side wall of the mobile phone clamp is provided with a groove. The shape and size of the groove are adapted to the 2.4G wireless receiver, making it easy to store the receiver when not in use and prevent it from being lost. At the same time, the groove can also hide the 2.4G wireless receiver when clamping the mobile phone, making it more aesthetically pleasing.

[0017] Furthermore, one end of the 2.4G wireless receiver is equipped with a USB male connector, preferably a TYPE-C interface, which can be plugged into and connected to the USB female connectors of gaming devices such as mobile phones, tablets, and desktop computers to achieve cross-device compatibility; depending on the usage requirements, the USB male connector can also be replaced with a Micro-USB or USB-A interface.

[0018] Furthermore, the mobile phone clamping part adopts an adjustable clamping structure (such as a spring clamping arm), the clamping width can adapt to mobile phones or tablets of different sizes, and the clamping direction is not limited, supporting the horizontal (two directions) or vertical placement of the device.

[0019] The advantages of this utility model compared with the prior art are:

[0020] 1. Low-latency connection for an enhanced gaming experience: Utilizing 2.4G wireless transmission technology, coupled with a low-power receiver main control chip and shielding design inside the receiver, data transmission latency is reduced by more than 50% compared to Bluetooth connections, and the anti-interference capability is stronger, making it especially suitable for competitive games and ensuring real-time response to operation commands.

[0021] 2. Adaptable to devices of varying thicknesses, resolving compatibility issues: The flat 2.4G wireless receiver (3-10mm thick) combined with a compact internal component layout can be adapted to mobile phones or other devices of different thicknesses, avoiding the placement imbalance or installation problems caused by the fixed interface height of traditional wired handles.

[0022] 3. Multi-directional placement, flexible adaptation to various scenarios: The phone holder supports horizontal (left-right) or vertical placement of the device, and can be flexibly adjusted according to the game screen ratio (such as horizontal competitive games and vertical casual games) to improve operating comfort.

[0023] 4. Cross-device compatibility, expanding usage scenarios: The 2.4G wireless receiver can connect to various devices such as mobile phones, tablets, and desktop computers through the cooperation of USB male connector and USB protocol chip, breaking through the single adaptation limitation of traditional gamepads and realizing "one gamepad for multiple uses".

[0024] 5. Convenient storage and prevention of loss: The groove design on the handle can store the unused 2.4G wireless receiver, preventing the receiver from being lost and improving portability. Attached Figure Description

Detailed Implementation

[0035] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0036] like Figures 1 to 8 As shown, the core of the mobile game controller assembly of this utility model is a separate structure of "controller part 1 + 2.4G wireless receiver 2": the controller part 1 transmits operation command signals through the built-in 2.4G wireless transceiver chip 12; the 2.4G wireless receiver 2 receives signals through the internal receiving main control chip 22, transmits them through the SPI / I2C interface to the USB protocol chip 23 to convert them into USB protocol signals, and then transmits them to external devices through the USB male connector 21; the mobile phone clamp 13 can flexibly fix the device and supports multi-directional placement, and the groove 14 is used to hide or store the 2.4G wireless receiver 2.

[0037] The component preparation and assembly of this utility model:

[0038] I. Handle Part 1:

[0039] The outer shell is made of ABS plastic injection molding, and the interior has reserved space for the installation of circuit board 11;

[0040] The circuit board 11 integrates a 2.4G wireless transceiver chip 12 (selecting the NRF24L01+ model with a transmission rate of ≥2Mbps to ensure low latency), a button control module, and a battery power supply module; the button operation signal is converted by the internal circuit and then transmitted to the 2.4G wireless transceiver chip 12.

[0041] The mobile phone clamping part 13 adopts a spring-driven telescopic clamping arm structure, which can clamp devices ranging from 4 to 12 inches; the inner side of the clamping arm is equipped with a silicone anti-slip pad to prevent the device from sliding.

[0042] The groove 14 is formed on the inner side wall of the clamping part, and its depth is adapted to the thickness of the 2.4G wireless receiver 2. It has a slight snap-fit ​​structure inside to ensure that the receiver will not fall off after being stored.

[0043] II. 2.4G Wireless Receiver 2:

[0044] Internal component assembly: The receiver control chip 22 (model NRF24L01), USB protocol chip 23 (model CH340G), and power supply module 24 (composed of voltage regulator capacitor, current limiting resistor and LDO voltage regulator chip) are sequentially soldered on the PCB substrate (thickness 1.6mm); the receiver control chip 22 and USB protocol chip 23 are bidirectionally electrically connected through SPI connection interface 27 (including SCK, MOSI, MISO and CS signal lines) for data transmission and status feedback;

[0045] Shielding and Encapsulation: The receiver main control chip 22 and the USB protocol chip 23 are covered with a metal shield 25 (0.2mm thick phosphor bronze material), which is fixed to the PCB substrate by solder points to reduce electromagnetic interference; an ABS plastic injection molded shell 26 (divided into an upper cover and a lower cover) is used, and the PCB substrate with soldered components is embedded in the lower cover. The USB male connector 21 (TYPE-C interface) extends from one end of the shell. The upper cover and the lower cover are sealed by ultrasonic welding, and the thickness is controlled within 5mm (preferably within the range of 3-10mm); the surface of the shell is treated with a frosted anti-slip texture to improve the insertion and removal feel.

[0046] The working process and usage method of this utility model:

[0047] I. Complete Signal Transmission Link:

[0048] When the buttons on the operating handle 1 are pressed, the button control module converts the mechanical operation into an electrical signal and transmits it to the 2.4G wireless transceiver chip 12.

[0049] The 2.4G wireless transceiver chip 12 modulates the electrical signal into a 2.4G frequency band wireless radio frequency signal, which is then transmitted through the built-in antenna.

[0050] The receiving main control chip 22 of the 2.4G wireless receiver 2 receives wireless radio frequency signals through its built-in antenna, demodulates them, converts them into standardized digital command data, and transmits them to the USB protocol chip 23 via the SPI connection interface 27.

[0051] The USB protocol chip 23 converts digital command data into signals that conform to the USB HID (Human Interface Device) protocol and transmits them to the USB interface of external devices (mobile phones / computers) through the USB male connector 21.

[0052] After receiving the USB signal, the external device parses it into operation commands that the game can recognize, enabling interaction between the controller and the device. At the same time, the device provides 5V voltage to the power supply module 24 through the USB interface. After voltage regulation, the voltage supplies power to the receiving main control chip 22 and the USB protocol chip 23. The USB protocol chip 23 feeds back the device connection status (such as successful connection / disconnection) to the receiving main control chip 22 through the SPI interface.

[0053] II. Mobile Phone Connection and Usage:

[0054] Remove the 2.4G wireless receiver 2 from the groove 14 of the handle part 1 and insert its USB male connector 21 into the TYPE-C interface of the mobile phone 3;

[0055] Turn on the power of the controller part 1. The 2.4G wireless transceiver chip 12 and the receiver's main control chip 22 will automatically pair (for first use, press the pairing button on the side of the controller. After successful pairing, they will automatically connect when powered on).

[0056] Adjust the clamping arms of the phone holder 13, place the phone 3 horizontally and clamp it (screen facing the handle operating surface), and you can then switch between landscape and portrait modes (e.g., ...). Figure 6 , Figure 7 and Figure 8 As shown, game operations (such as shooting and racing games) are transmitted in real time through the above-mentioned link.

[0057] III. Connection and storage of other equipment:

[0058] When connecting a tablet, the steps are the same as for a mobile phone. The mobile phone clamp 13 adapts to the size of the tablet through the telescopic clamp arm. If the tablet is too large and exceeds the clamping range of the telescopic clamp arm, the tablet can be placed directly on the desktop or tablet stand. When connecting a desktop computer, insert the 2.4G wireless receiver 2 into the computer's USB-A port (a TYPE-C to USB-A adapter is required). The USB protocol chip 23 automatically adapts to the computer's USB HID protocol without the need for additional driver installation.

[0059] After use, unplug the 2.4G wireless receiver 2, insert it into the groove 14 of the handle part 1, turn off the power of the handle, and you can carry it as a whole to avoid losing the receiver.

[0060] General compatibility instructions for this utility model: In this embodiment, the USB male connector type, thickness (within the range of 3-10mm), and interface type (which can be replaced with I2C interface) of the 2.4G wireless receiver 2 can be adjusted according to requirements: for example, a Micro-USB male connector can be used for older devices, and a BLE+2.4G dual-mode receiver chip can be selected for low power consumption requirements. As long as the core concept of "2.4G wireless communication + separate flat receiver (including receiver main control and USB protocol chip, and the two are connected through SPI / I2C interface) + multi-directional clamping" is adopted, it falls within the protection scope of this utility model.

[0061] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
