Description

M258620 4. Creation Description (1) [Technical Field to which the New Type belongs] This creation "Electric-free Safety Light Shoes" aims to provide a shoe that can emit light without the need for batteries to provide electricity. [Previous technology] In recent years, light-emitting diodes (LIGHT EMITTING DIOD), which are used for lighting or marking, are abbreviated as LEDs, and have been widely used in flashlights, table lamps, traffic lights, and indicators. Mainly because LED has less power consumption, less heat generation, long life, impact resistance, etc., it is superior to traditional white and fluorescent lamps.

Recently, it is often seen that manufacturers use these characteristics of LEDs to install LEDs on children's shoes to make children's shoes that can emit light. However, most of their purposes are not from safety considerations, but from shape considerations, which can be said to be an alternative child. Toys are highly entertaining. These luminous children's shoes also use LEDs to emit light, but are powered by dry batteries. The structure of general luminous children's shoes is shown in the first figure, which consists of a shell seat A1 and a shell cover A2. The plastic case is covered with a substrate A 3, two batteries A 4, a flashing ICA 5, a vibration switch A 6 and a plurality of wires A 7 extending outside the plastic case, and each of the ends of the plurality of wires A 7 is combined with a light. Diode (LED) A 8,

It can be installed inside the heel of the shoe. When the vibration switch A 6 is triggered by the user's walking motion, the flashing I C A 5 controls the LED D 8 to flash in a proper manner a number of times. However, the above structure requires so many constituent parts. In addition, the main constituent parts are electronic parts, which are basically afraid of water and impact.

Page 5 M258620 IV. Creation instructions (2) The pool is also a consumable product that needs to be replaced. Therefore, it is necessary to remove the plastic casing from the shoes and replace it with a new battery, so it is very difficult to make it completely waterproof. In addition, the instructions of the luminous children's shoes sold on the market all indicate the restrictions that they cannot be impacted, they are strictly prohibited from wearing under water, and they are not washable. In fact, such restrictions are not applicable to children's shoes. [New content] The main purpose of the creation of "electricity-free safety light shoes" is to embed a piezoelectric device at an appropriate position on the shoe. The output end of the piezoelectric device is equipped with more than one light-emitting element. When walking around wearing shoes, the piezoelectric device generates electric current under pressure, which causes the light-emitting elements to emit light, so that the shoes can emit light without a battery, and has the effect of beautiful appearance and warning. The piezoelectric device is composed of a rigid circuit board and piezoelectric elements attached to the upper and lower surfaces of the piezoelectric device. The piezoelectric element is bent and displaced by an external force, and a current is generated to cause the light-emitting element to emit light. [Implementation] In order to make your reviewing committee aware of the composition of this creation, and the overall operation mode, the drawings are explained as follows: This creation is a "electric-free safety light shoe" whose structure is shown in the second and third pictures The piezoelectric device 2 is embedded in the toe part 11 or the heel part 12 of the base of the shoe 1, and the output ends of the piezoelectric device 2 are combined.

M258620 IV. Creation instructions (3) There is more than one light-emitting element 3 (the light-emitting element in this case is an LED). When a user wears shoes and walks, the piezoelectric device 2 is pressed to generate a current, so that the light-emitting element 3 Emit light. When manufacturing, firstly, a box body 4 having an opening 41 is made of a resin material. The piezoelectric device 2 and the light-emitting element 3 are placed in the box body 4 and the light-emitting element 3 is exposed at the opening 41, and then filled. An appropriate amount of resin is placed at the opening 41, and then the heel and toe of the base of the shoe 1 are drilled and inserted into the box 4 and then fixed with silicone (not shown). It can also be placed outside the light-emitting element 3. A transparent lens (not shown) is provided to increase the amount of light.

Among them, the piezoelectric device 2 is a combination of two piezoelectric ceramic 2 1 (PIEZ 0) thin plates on the two outer sides of the substrate 2 2. As shown in the fourth figure, a piezoelectric effect is used to stretch one sheet and the other Compressive bending displacement method obtains electric power. Piezoelectric ceramics are made of barium titanate (BARIUM TITAN ATE BaTi 03) and lead zirconate titanate (LEAD ZIRCONIATITANATE Pb (Zi, Ti) 〇3) at high temperature and solidified to produce a polycrystalline ferroelectric body. Here, Piezoelectricity does not appear in this state. This structure consists of polycrystalline particles,

The direction of the electric multipole in each sub-domain is different, so the overall electric moment of the bipolar (ELECTRICAL PAIR POLES MOMENT) is zero. Therefore, in order to give the characteristics of piezoelectricity, it will be polarized while heating (increasing the DC strong current boundary, the electric dipole will be concentrated in a certain direction), please refer to the fifth diagram (A) and (B), In this way, the piezoelectric ceramics have strong piezoelectricity because of the strong electric property. Even if the electrical boundary is removed, the bipolar moment will remain. Piezo BYM0LPH due to external force

Page 7 M258620 IV. Creative Instructions (4) The bending displacement caused electricity. When the user wears shoes 1 and walks, as shown in Figures 6 and 7, the pressure on the sole surface of the foot will be irregular and intermittent, so the light-emitting period and brightness of the light-emitting element 3 will also be irregular, so no special The switch or sensor has a very simple structure, which not only saves costs and reduces the damage rate, but also does not require the installation of external power sources such as batteries, which can save the trouble of repair or replacement. At the same time, the resin box body and resin are used as filling materials, which can take into account Only water and impact resistance. The creation of "electricity-free safety light shoes" provides a better light shoe structure, especially the use of piezoelectric devices, not only eliminating the need for external power supplies such as batteries, but also saving the trouble of maintenance or replacement, and proposed a new type according to law Patent application; however, the above description of implementation and drawings are one of the preferred embodiments of this creation, not to limit this creation, but to approximate the structure, installation, features, etc. of this creation, Those who are similar should fall within the scope of the purpose of creation and the scope of patent application.
