Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] To make the technical solution and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0025] Please see Figures 1 to 4 This embodiment provides a basic implementation of a multifunctional charging handle.

[0026] The core of the multi-functional charging handle lies in a hollow shell 1. This shell 1 is integrally molded from high-strength, lightweight engineering plastics (such as ABS or PC / ABS alloy) using an injection molding process, forming a well-organized internal space for housing all internal functional components. The shell 1 is ergonomically designed with an arc shape for easy gripping. Its lateral dimension is slightly larger than the width of an adult's palm, while its vertical height provides sufficient internal space to accommodate large-capacity battery cells, ensuring stability when held. To further enhance grip stability and comfort, an anti-slip pad 11 is fixed to the surface of the shell 1 using double-sided adhesive or clips. This anti-slip pad 11 is preferably made of soft rubber or silicone, with a textured surface (such as a diamond pattern or wave pattern) to effectively increase friction and prevent slippage during prolonged shooting or when hands are sweaty.

[0027] The top opening of the housing 1 is secured to the top cover 3 via a snap-fit. A spherical cavity is located at the center of the top cover 3. A mounting bracket 2 is inserted into this spherical cavity via a ball head 21 at its lower end, thus achieving a ball-joint connection between the mounting bracket 2 and the top cover 3. The ball head 21 is preferably made of nylon and has a rubber coating, forming a nylon-coated ball head. This treatment increases the friction between the ball head 21 and the spherical cavity of the top cover 3, providing moderate damping during angle adjustment; furthermore, nylon material possesses good strength and wear resistance, while the rubber coating effectively reduces noise and wear during rotation. To lock the angle, the top cover 3 is equipped with a threaded knob 31. When the knob 31 is rotated clockwise, it compresses the ball head 21, causing a sharp increase in friction between it and the spherical cavity, thereby firmly locking the mounting bracket 2 at any angle desired by the user; rotating the knob 31 counterclockwise releases the clamp, allowing the user to freely adjust the angle. The upper part of the mounting bracket 2 is typically a 1 / 4-inch standard threaded stainless steel rod, which is the most common interface standard in the photography industry. It can be directly screwed into the bottom screw holes of most photography accessories such as cameras, mobile phone clips, and fill lights, achieving extremely high device compatibility.

[0028] The bottom of the housing 1 is secured to a bottom cover 4 by screws. A bracket nut 42, preferably a 1 / 4-inch brass nut, is embedded in the center of the bottom cover 4. This nut is intended to allow the entire handle to be mounted as a single unit onto photographic support systems such as tripods, monopods, and sliders, which also have 1 / 4-inch threads. A silicone pad 41 is attached to the bottom surface of the bottom cover 4. This silicone pad 41 serves multiple purposes: firstly, it provides excellent anti-slip properties when the handle is placed on a smooth surface such as a table, preventing accidental movement; secondly, it acts as a cushioning and shock absorber, protecting the surface from scratches and slightly absorbing external vibrations; and thirdly, it raises the distance between the bottom and the table, preventing direct contact and wear between the threads of the bracket nut 42 and the table surface.

[0029] The internal structure of the handle is fundamental to its functionality. See also Figure 3 and Figure 4 Inside the housing 1, there is a support 5 that serves as a framework. This support 5 is typically made of metal (such as aluminum alloy) or high-strength plastic and is connected to the fixing posts on the inner wall of the housing 1 by screws. The main function of the support 5 is to provide precise mounting positioning and stable support for the main board 6 and the battery cell 7, preventing them from shaking inside the housing 1 and improving the structural strength and impact resistance of the product.

[0030] The battery cell 7 is the power source for the controller, typically consisting of one or more lithium polymer batteries or 18650 lithium-ion batteries connected in series. Its capacity can be selected according to needs to provide long battery life. The battery cell 7 is connected to the mainboard 6 via wires. The mainboard 6 is the "brain" of the entire controller; it is a printed circuit board (PCB) that integrates a power management chip (responsible for charge / discharge management, power calculation, and circuit protection), a microcontroller (MCU), and related resistors and capacitors.

[0031] To protect the internal precision components, multiple layers of buffer and insulating materials are provided between the battery cell 7 and the main board 6, and between the battery cell 7 and the housing 1. Specifically, foam 71 is padded in the contact area between the battery cell 7 and the main board 6. This foam 71 has good elasticity and compressibility, which can absorb and disperse external impact forces. Between the foam 71 and the battery cell 7, a layer of barley paper 72 is also sandwiched, and barley paper 72 is also provided at both ends of the battery cell 7. This is a high-performance insulating material used to ensure complete insulation between the electrodes of the battery cell 7 and any lines on the main board 6, preventing the risk of short circuits.

[0032] To expand the charging functionality, a smaller sub-board 61 is installed above the mainboard 6. The sub-board 61 integrates one or more charging ports 611. This charging port 611 has bidirectional charging functionality: when an external power adapter is plugged into the charging port 611, it can charge the battery cell 7 inside the controller; when the controller has power inside, the charging port 611 can also be used as an output port to power external devices through another data cable.

[0033] In addition, one end of a charging cable 8 is directly soldered to the main board 6 or the sub-board 61, and the other end extends from an opening on the side of the housing 1. When not in use, the charging cable 8 can be wound into a specially designed groove on the side of the housing 1 to form a loop, which is convenient for storage, avoids cable clutter, and makes it easy for users to hang and carry. A display screen 62 and a button 63 are also provided on the surface of the housing 1. The display screen 62 is used to display the remaining battery percentage or voltage information of the controller in real time and intuitively, while the button 63 is used for powering on / off, switching display modes, and other operations.

[0034] In use, the user first screws the camera and other equipment onto the threaded rod of the mounting bracket 2. For handheld shooting, simply hold the handle; the anti-slip plate 11 provides a stable grip. To adjust the shooting angle, simply loosen the knob 31, adjust the camera to the desired angle, and then tighten the knob 31 to lock it in place. For fixed-position shooting, the handle can be mounted to a tripod via the bracket nut 42 on the bottom cover 4. When the camera battery is low, the user can use the charging cable 8 included with the handle or a separate data cable to connect the camera to the charging port 611 of the handle to charge it, and monitor the remaining battery level of the handle in real time via the display screen 62.

[0035] In summary, this utility model effectively integrates three major functions: a power bank, a handheld handle, and an adjustable universal bracket, solving pain points faced by photography enthusiasts, video bloggers, and live streamers, such as numerous devices, poor compatibility, battery anxiety, and inconvenience in fixing angles. Its structural design is reasonable, highly modular, and versatile, fully demonstrating its practicality and innovation.
