Description

Technical Field

[0001] This invention belongs to the field of artificial Christmas trees in International Patent Classification (IPC) A47G 33 / 06, and specifically relates to a self-powered simulated Christmas tree decoration assembly device and its application. Background Technology

[0002] Christmas tree decorations typically include an artificial Christmas tree and a matching special Christmas tree base. They are a type of holiday decoration product widely used in homes, shopping malls, hotels, and various public places.

[0003] In practical use, Christmas tree decorations typically involve hanging strings of lights on artificial Christmas trees to create a festive and warm holiday atmosphere. Currently, most Christmas tree decorations use independent external strings of lights, which need to be hung on the branches of the artificial tree. There are two main power supply methods: one is the external AC power type, where the strings need to be plugged into a separate AC outlet. This involves long extension cords, messy wiring, and exposed cables that are prone to tangling and wear, not only ruining the overall neatness and aesthetics of the Christmas tree but also posing safety hazards such as tripping hazards and electrical leaks. The other is a battery box power supply structure, where the battery box has no fixed installation structure and is usually hung on the Christmas tree or placed in the base. The strings, battery box, and base are independent of each other, making them easily separated during storage, leading to the loss or damage of parts. Furthermore, common artificial Christmas tree bases are usually three- or five-pronged iron frames, which are sturdy enough but lack aesthetic appeal, and the iron frames are prone to rust, affecting future use.

[0004] To address the numerous shortcomings of existing technologies, this invention provides a self-powered simulated Christmas tree decoration assembly. By integrating the power supply within the base and providing a standardized interface for connecting the light strings, it enables rapid connection and power-on of the light strings. This solves the problems of messy wiring caused by external mains power, exposed cables prone to tangling and wear, and the battery box being independent of the base, making it susceptible to loss or damage during transport and storage. Summary of the Invention

[0005] This invention aims to solve the problems existing in current usage, such as external power sockets, exposed wires, unsightly external power boxes, safety hazards, messy wiring, and unattractive bases, which affect consumer use and appreciation. It provides at least one beneficial alternative. Specifically, this invention provides a self-powered simulated Christmas tree decoration assembly device. By combining various components, it forms a simulated Christmas tree base with an aesthetically pleasing base and a combination of LED light strings with eight flashing modes and a timer mode. It combines aesthetics and practicality, representing not just a simple assembly, but an upgrade and innovation in functionality.

[0006] The inventive concept of this invention is as follows: A self-powered artificial Christmas tree decoration assembly includes a base shell, a power controller, two sets of wire-to-wire connectors, and two strings of LED lights. The sub-wire ends of the connectors are connected to the LED lights, and the bus ends of the connectors are connected to the power controller. The base shell is used to protect the power controller and fix the artificial Christmas tree. The two sets of LED lights are used to decorate the inside of the base and to decorate the artificial Christmas tree.

[0007] Therefore, a first aspect of the present invention provides a combination device for a simulated Christmas tree decoration combination device with a self-powered power supply.

[0008] The base shell consists of a base shell with openwork on all four sides and four plastic window grilles.

[0009] The base shell is filled with 30-50% calcium carbonate and has a cantilever beam notch impact strength ≥10KJ / m. 2 The shell is made of white or brown modified polypropylene material by injection molding.

[0010] The window grille consists of two parts: component 1 is filled with 30-50% calcium carbonate, and the cantilever beam notch impact strength is ≥10KJ / m. 2 The window grille is made of white or brown modified polypropylene material by injection molding and has a buckle that can be fixed around the base. Part 2 is made of random copolymer polypropylene raw material (melt index above 5g / 10min) of (100~150)mm*(50~100)mm*(0.5~1.0)mm by injection molding. Part 2 has a smooth front and a frosted back with EDM treatment. Part 1 is used as the outer structural component and Part 2 is used as the inner structural component.

[0011] In this invention, 30-50% calcium carbonate is used as filler, and the notched impact strength of the cantilever beam is ≥10KJ / m. 2White or brown modified polypropylene is used for both the base shell and the window grille. This is because calcium carbonate-filled modified polypropylene has a higher density, preventing the base from tipping over after the Christmas tree is installed due to its lightness. Additionally, the material is relatively inexpensive, has high impact strength and good toughness, and is less prone to cracking from impacts or other external forces, thus ensuring continued use. White or brown are chosen to match the Christmas tree colors, making these two colors suitable. The window grille is not directly injection-molded onto the base shell but is attached using clips. This is primarily to reduce mold costs and allow for diverse window grille designs. The hollowed-out base shell significantly reduces mold development difficulty and costs. Furthermore, the individual window grille mold is a small-scale design, allowing for the creation of different types of window grilles, enhancing aesthetics. Window grille component 2 is injection-molded from random copolymer polypropylene (melt index above 5g / 10min). Random copolymer polypropylene has high light transmittance, low density, and is inexpensive. The combination of a smooth surface on one side and a frosted surface on the other reduces eye discomfort during flashing without reducing brightness, demonstrating a highly innovative design.

[0012] Preferably, the calcium carbonate-filled modified polypropylene is selected with 40% calcium carbonate filler, and the impact strength is 13±1 KJ / m. 2 Modified polypropylene. With 40% calcium carbonate filler, it has a lower material cost and a higher density of approximately 1.22 g / cm³. 3 The base is quite stable and sturdy, with an impact strength of 13±1KJ / m. 2 During production, conventional copolymer polypropylene can be used as the base material. The raw material is widely available, so costs are not significantly increased. Many factories produce similar modified polypropylene, and cost-effective modified polypropylene can be found on the market. (13±1KJ / m) 2 Its impact strength is sufficient to withstand most impact and drop tests, preventing the casing from cracking due to the base falling or being hit by other objects, thus ensuring its continued use.

[0013] The power controller consists of a printed circuit board, a battery box, a switch button, or a remote control. The printed circuit board is an 8-mode timed LED string light control board. The 8 light modes are: cycle all effects mode, wave gradient, mutual flash, single light gradually brightening and dimming, star flash + mutual flash, two lights gradually brightening and dimming simultaneously, star flash, and two lights constantly on without flashing. The timer mode is a multi-level timer control that can be set to 2 hours, 4 hours, 6 hours, 8 hours, 12 hours off or 24 hours constant on. The circuit board has two built-in wires for connecting to the connector bus of the light string.

[0014] The printed circuit board (PCBA) is the core component of the electronic system in the Christmas tree base of this invention. It features 8 built-in lighting modes and a timer function, satisfying consumers' demands for functionality and practicality. The PCB design is mature and inexpensive. Its compact size makes it suitable for placement in an empty space at the bottom of the base. It uses four AA batteries, making power replacement convenient and inexpensive, and eliminating the safety hazard of electric shock. The power switch is conveniently located on the side of the base. A single button switches between different light-off modes, but only one timer mode can be activated at a time, typically 6 hours for illumination and 18 hours for deactivation. Powering on will default to the previous illumination mode. An external remote control allows for multiple light-off modes and timer functionality, offering convenient operation.

[0015] The wire-to-wire connector is a 2.54mm SM-2P male-female connector. The SM-2P male-female connector requires no soldering; wiring can be completed simply by plugging and unplugging. The interface design is robust, preventing detachment after insertion, ensuring stable contact performance. It features a built-in anti-reverse insertion structure, preventing incorrect insertion and avoiding damage to equipment. Its compact 2.54mm spacing design makes it suitable for installation scenarios with limited base space. This is a rational choice based on actual usage environments, utilizing the most suitable resources to create maximum value, demonstrating both practicality and innovation.

[0016] The LED light string is composed of PVC wire, heat shrink tubing, intermediate isolation column, and LED beads with copper terminals; The LED light strings come in two colors. The LED strings placed inside the base consist of 10-20 LEDs made of white or brown PVC wire and heat-shrink tubing. The LED light strings used to wrap the simulated Christmas tree consist of 50-100 LEDs made of grass-green PVC wire and heat-shrink tubing. The heat-shrink tubing is made of PVC material with a heat shrink ratio of (2-2.5):1. The intermediate spacer is a polypropylene spacer strip with a hot melt adhesive layer adhered to the outside.

[0017] This invention utilizes heat-shrinkable LED light strings, with an outer layer of PVC insulation and an inner layer of hot melt adhesive. After heating and shrinking, it completely wraps around the exposed joints of the light string, effectively preventing leakage and short circuits. The PVC heat-shrinkable tubing is low-cost, easy to process, and inherently possesses flame-retardant properties and excellent electrical insulation. It shrinks rapidly when heated to above 98°C. The central insulating column, after heating, is encased in the heat-shrinkable tubing, effectively isolating the positive and negative terminals with copper tabs and preventing short circuits.

[0018] The second aspect of the present invention provides an application field for the self-powered simulated Christmas tree decoration assembly device described in the first aspect of the present invention.

[0019] Specifically, the application of the self-powered simulated Christmas tree decoration assembly equipment in simulated Christmas tree decoration.

[0020] This invention, a self-powered simulated Christmas tree decoration assembly, is more aesthetically pleasing than the commonly seen iron frame bases on the market. It is carefully equipped with a power controller consisting of a printed circuit board, battery box, and switch button or remote control. It connects to heat-shrinkable LED light strings via a female-female connector. By combining the various components, a beautiful base is formed, along with a combination of LED light strings featuring 8 flashing modes and a timer mode. It combines aesthetics and practicality, and is not just a simple assembly, but an upgrade and innovation in functionality.

[0021] Compared with the prior art, the combined device provided by the present invention has the following advantages: (1) In terms of appearance, the plastic base is exquisite and the window pattern structure can be selected in various ways. The white base is clean and tidy, while the brown base is pleasing to the eye. It is equipped with built-in power LED light string with 8 light-off effects. The power components are not exposed and the power cord will not be messy and affect the appearance.

[0022] (2) In terms of function, it has 8 light-off effects and multiple timer modes, with rich functions. It has a built-in power cord, so there is no need to run wires. After purchasing, consumers can plug in the artificial Christmas tree, arrange the green LED light strings according to their own wishes, turn on the lights, and enjoy the beautiful artificial Christmas tree, which will enhance the festive atmosphere.

[0023] (3) In terms of durability, high-impact modified polypropylene filled with calcium carbonate is selected. The base shell can be dropped freely from a height of 0.5m and the bottom surface of the base can be dropped parallel to the ground. It can be dropped 20 times without cracking. If it is dropped from the bottom corner, it can be dropped 4 times without cracking. It will not crack due to accidental drop, which will affect the later use.

[0024] (4) This invention selects specific types and parameters of electronic and electrical components and plastic materials, and through reasonable combination, forms a brand-new, safe, innovative and practical combined device. Detailed Implementation
