Abstract
Description
Technical Field
[0001] This invention relates to the field of doll equipment technology, and more specifically to a method for using a pairing toy. Background Technology
[0002] There are many small toys on the market that can be used as keychains or backpack charms, hanging on backpacks, keychains, or mobile phones to meet the wearing needs of different users. They can be played with during leisure time, such as while waiting for a bus or resting in a seat. In today's society, their demand is very high.
[0003] To increase the playability of the small dolls, a control board is usually installed inside, which is electrically connected to a switch and LED light components. By pressing the switch, the LED lights can be turned on, but the effect is generally poor and it does not have any social function.
[0004] In today's society, many people work and study in the same environment, and they use mobile apps such as message in a bottle to find friends and experience fate. However, these are all virtual ways. Whether you can experience it through real-life interaction is another matter. If you throw a message in a bottle into a river or the sea and expect someone to find it, the chances are probably very low. The bottle might even be collected and disposed of as trash before it is found.
[0005] If one could find fate and make friends through small toys, they wouldn't be disposed of as trash and could achieve a certain effect. However, such toys do not exist at present. Summary of the Invention
[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for pairing toys. It can be carried and played with as a pendant or other means, or by bringing two toys of different genders close together and detecting pairing through two Bluetooth modules, the toys can find a friend and achieve the effect of finding a friend, thus meeting the user's needs.
[0007] The solution of the present invention to the aforementioned technical problem is:
[0008] A method for using a pairing toy, comprising the following steps:
[0009] (1) Prepare at least one pair of dolls and sell them to at least two users through distribution or sales channels;
[0010] (2) The user carries the doll with him / her at all times;
[0011] (3) The user presses the control switch of the doll to turn it on;
[0012] (4) The doll's colorful LED light components begin to flash;
[0013] (5) When the two dolls are within a suitable range, if the Bluetooth modules of the two dolls have the same pairing password, the pairing will be successful; if the Bluetooth modules of the two dolls have different pairing passwords, the pairing will fail.
[0014] (6) According to step (5), when the Bluetooth module is successfully paired, the doll’s buzzer will sound, and at the same time, the seven-color LED light assembly will flash in the corresponding color.
[0015] (7) According to step (5), when the Bluetooth module fails to pair, the doll's buzzer will not make a sound, and at the same time, the seven-color LED light assembly will flash normally. At this time, the other party cannot be found.
[0016] (8) According to step (6), locate the other party based on the sound emitted by the nearby buzzer.
[0017] Furthermore, in step (6), if you do not want the buzzer to make a sound, you can press the control button and the corresponding doll's buzzer will stop making a sound.
[0018] Furthermore, in step (1), more than 100 pairs of dolls are prepared.
[0019] Furthermore, in step (5), the appropriate range for the two dolls is within a radius of 20m.
[0020] Furthermore, the doll's seven-color LED light assembly (3) flashes red, green, blue, yellow, cyan, purple, and white in a cycle when it is normally turned on.
[0021] The outstanding effects of this invention are:
[0022] 1. It can be carried and played with as a pendant or other ornament.
[0023] 2. It works by bringing two dolls of different genders close together and detecting pairing via two Bluetooth modules. When they are successfully paired, a seven-color LED light illuminates to indicate that they have found a friend, thus achieving the effect of finding friends by chance. This meets the user's needs, and the dolls are not easily disposed of as waste. Attached Figure Description

[0025] Figure 2 This is a partially exploded schematic diagram of the doll of the present invention as a female cat-shaped doll. Detailed Implementation
[0026] For example, see below. Figures 1 to 2 As shown, a method for using a pairing toy includes the following steps:
[0027] (1) Prepare at least one pair of dolls 10 and sell them to at least two users through distribution or sales channels; 100 pairs or more pairs of dolls 10 may be sold or distributed in an area as needed;
[0028] (2) The user carries the doll 10 with him / her; it can be worn on a mobile phone, bag or key.
[0029] (3) Users can press the control switch of the doll 10 in crowded places to turn it on; after pressing the control switch for 3 seconds, it will be turned on, causing the control motherboard 1 to control the corresponding seven-color LED light assembly 3 to flash.
[0030] (4) The seven-color LED light component 3 of the doll 10 begins to flash in a cycle of red, green, blue, yellow, cyan, purple and white;
[0031] (5) When the two dolls 10 are within a suitable range, in this embodiment, within a radius of 20m, if the Bluetooth modules of the two dolls 10 have the same pairing password, then the pairing is successful; if the Bluetooth modules of the two dolls 10 have different pairing passwords, then the pairing is unsuccessful.
[0032] (6) According to step (5), when the Bluetooth module is successfully paired, the buzzer 2 of the doll 10 emits a sound, and at the same time, the seven-color LED light assembly 3 flashes the corresponding color.
[0033] (7) According to step (5), when the Bluetooth module fails to pair, the buzzer 2 of the doll 10 will not make a sound, and at the same time, the seven-color LED light assembly 3 will flash normally. At this time, the other party cannot be found.
[0034] (8) According to step (6), locate the other party based on the sound emitted by the nearby buzzer 2.
[0035] In step (6), if you do not want the buzzer 2 to make a sound, you can press the control button 4 to control the main board 1 to obtain the model number and control the corresponding doll 10's buzzer 2 to stop making a sound, so that the user is not found by other users who have successfully paired up.
[0036] This method in the embodiment can also be applied to pairing in some large-scale outdoor games.
[0037] In this embodiment, each pair of dolls 10 consists of dolls of different genders, one being a male cat-shaped doll and the other a female cat-shaped doll.
[0038] Two dolls 10 are attached to backpacks 20 by straps. The backpacks 20 have transparent panels. One doll 10 is a male cat doll with a blue coating on the outer wall of its backpack 20. The other doll 10 is a female cat doll with a pink coating on the outer wall of its backpack 20.
[0039] Each doll 10 has two arms whose ends are inserted into the main body. These arms are detachable and can be disassembled, repositioned, and then reinserted to change the position of the arms and meet the user's play needs.
[0040] Each doll 10 has a fixed control board 1. The control board 1 is connected to a lithium battery, a buzzer 2, a seven-color LED light assembly 3, a Bluetooth module and a control button 4 when powered on.
[0041] The lithium battery provides power to the buzzer 2, the seven-color LED light assembly 3, the Bluetooth module and the control button 4. The Bluetooth module has a pairing password.
[0042] The shell of the doll corresponding to the seven-color LED light assembly 3 is transparent, that is, the wall panel of the backpack 20 corresponding to the seven-color LED light assembly 3 is transparent without any coating.
[0043] In this embodiment, the control motherboard 1 and other components are installed in the backpack 20. The backpack 20 includes a main shell and a cover plate, which are fixed together by bolts. The bottom plate of the backpack 20 has a charging port and a sound-transmitting port. The charging port connected to the control motherboard 1 is inserted into the charging port, and the sound-emitting end of the buzzer 2 faces the sound-transmitting port. The control button 4 is fixed to the backpack 20, and its pressing part is inserted into a through-hole on the rear wall panel of the backpack 20.
[0044] The specific principle of this embodiment is as follows: When the control buttons of the two dolls 10 are turned on and the two dolls 10 are brought close together, and the pairing passwords of the two Bluetooth modules are the same, the two Bluetooth modules pair directly. At this time, the Bluetooth module pairing success signal is sent to the control motherboard 1. The control motherboard 1 processes the sensing signal and controls the corresponding buzzer 2 to emit a sound. At the same time, it controls the corresponding seven-color LED light component 3 (the seven-color LED light component 3 flashes in the corresponding color through the control motherboard. The principle is that the seven-color LED light component mainly uses the RGB three-primary-color mixing principle. The controller adjusts the mixing of red, green and blue LED beads and adjusts the brightness ratio of the three to achieve color change. This is an existing conventional structure and is known content, so it will not be described in detail here) to present the corresponding color flashing (such as pink). If both dolls 10 have this effect at the same time, then both dolls 10 will simultaneously flash the corresponding color and the buzzer 2 will emit a sound. If it is a single doll, then the other one will not change the color of the seven-color LED light component 3, but the buzzer 2 will emit a sound.
[0045] When the control button is turned on, the pairing passwords for the two Bluetooth modules are different, so the two Bluetooth modules do not pair directly. The seven-color LED light components 3 of the two dolls 10 flash in seven colors in a cycle, and the buzzer 2 does not make a sound.
[0046] It is highly playable.
[0047] The above embodiments are only used to illustrate the present invention and are not intended to limit the present invention. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also fall within the scope of the present invention, and the patent protection scope of the present invention should be defined by the claims.
