Description

BL-5149 1 ELECTRONIC TABLE CLOTH LU101889 Technical Field The present invention relates to electronic table cloth, and belongs to the technical field of smart home. Background Art A dining table is a place where people share delicious food and spend memorable time. With one piece of dining table cloth, people will feel warm and pleasant when dining, have a deep impression and feel unforgettable. Therefore, the dining table cloth becomes one of the necessary elements for daily home and environmental decoration of restaurants and tea houses.

Through retrieval, it was found that the Chinese patent application CN 105910059 A disclosed LED table cloth with the luminescent color changing with the temperature, and it solves the problem that in the prior art, one LED table cloth can only emit one color or a plurality of colors and the color and the intensity are fixed.

However, the electronic table cloth is not provided with an external interface, and thus, displayed contents of the electronic table cloth cannot be controlled. Moreover, because the table cloth has the characteristic of softness, when the table cloth is coiled or folded, short circuit or open circuit of LED circuits is easily caused.

Technical problem The present invention is directed to overcome the above-mentioned drawbacks in the prior art and to provide electronic table cloth. Technical solution The above purpose is realized by the following technical scheme: the present invention provides electronic table cloth, including a first flexible layer and a second flexible layer which are insulating and arranged from top to bottom, LED lamp beads being fixed between the first flexible layer and the second flexible layer and a light-emitting surface facing upwards, and an LED driving module being connected with the LED lamp beads through wires, wherein an insulating film is further arranged between the first flexible layer and the second flexible layer, wires are respectively arranged on a front surface and a back surface of the insulating film, one pin of each LED lamp bead is directly connected with the wire on the front surface of the insulating film, the other pin of each LED lamp bead penetrates through the insulating film and is then connected with the wire on the back surface of the insulating film, a touch switch is arranged on an upper surface of the first flexible layer, a switch signal output line of the touch switch and a signal input line of an LED driving module are fixed between the first

BL-5149 2 flexible layer and the second flexible layer, an outer end is connected with a power supply plug-in interface, and, 101889 the power supply plug-in interface 1s fixed to a lower portion of an edge of the second flexible layer.

Beneficial effects The electronic table cloth of the present invention 1s provided with the touch switch, external interfaces are reserved for the LED driving module and the touch switch, the displayed contents of the electronic table cloth can be controlled through external equipment, and possibility is provided for enhancing the interactivity of the electronic table cloth. Moreover, the electronic table cloth is low in manufacturing cost and maintenance cost, and is suitable for being used in families, restaurants and tea houses. The electronic table cloth adopts the dual in-line package LED lamp beads, the LED lamp beads are fixed through the insulating film, the wires connected with the two pins of each LED lamp bead are respectively arranged on the front surface and the back surface of the msulating film, and thus, open circuit of surface mount device LED lamp beads in a bending process is avoided. Brief Description of the Drawings Fig. 1 is a schematic structural view of electronic table cloth.

Fig. 2 is a distribution view of LED lamp beads on an insulating film.

Fig. 3 is a schematic exploded view of the LED lamp beads and the insulating film.

The reference numbers in the drawings are indicated below.

1-first flexible layer, 2-insulating film, 3-second flexible layer, 4-touch switch, 5-LED lamp bead, 6-first wire, 7-second wire, 8-first pin, and 9-second pin.

Detailed Description of the Invention The present invention is further described below in connection with the accompanying drawings and specific embodiments.

As shown in Fig. 1, Fig. 2 and Fig. 3, electronic table cloth of the present embodiment includes a first flexible layer 1, an insulating film 2 and a second flexible layer 3 which are insulating and arranged from top to bottom, LED lamp beads 5 (edgeless dual in-line package LED lamp beads) are arranged in an array mode, and fixed on a front surface of the insulating film 2, and a light-emitting surface faces upwards, and an LED driving module (not shown) is connected with the LED lamp beads 5 through wires. The LED driving module is an existing mature circuit and can be directly purchased from a manufacturer, and the internal structure of the LED driving module 1s not described in the present embodiment. Circuit connection between a driving circuit and the LED lamp beads 5 belongs to the prior art, and the present embodiment does not provide corresponding

BL-5149 3 accompanying drawings for explanation. A first wire 6 and a second wire 7 are respectively arranged on the front, 101889 surface and a back surface of the insulating film 2, a first pin 8 of each LED lamp bead 5 is directly connected with the first wire 6 on the front surface of the insulating film 2, and a second pin 9 of each LED lamp bead 5 penetrates through the insulating film 2 and is then connected with the second wire 7 on the back surface of the msulating film.
