Description

Technical Field

[0001] This utility model belongs to the field of entertainment equipment technology, specifically relating to a game card that can be controlled to emit light without contact. Background Technology

[0002] Chess and card games are a general term for board and card games, including Chinese chess, Go, international chess, Mongolian chess, Gomoku, checkers, international checkers, military chess, bridge, poker, mahjong and many other traditional or emerging entertainment games. They are also a kind of traditional culture. If mahjong cards on the market have embedded chips and circuits inside, they are generally made by secondary injection molding, which is more expensive, resulting in higher mold and production costs.

[0003] Existing mahjong-style game cards require secondary injection molding during packaging, and the injection port needs to be polished after injection molding. This results in poor display effects, time-consuming and labor-intensive assembly, and high production costs. To address this, we propose a game card that allows for contactless control of light emission. Utility Model Content

[0004] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide a game card that can control the light emission without contact, so as to solve the problems mentioned in the background art that the existing mahjong-style cards have poor display effects, are time-consuming and labor-intensive to assemble, and have high production costs.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a game card that can control light emission without contact, comprising an upper shell and a base. The surface of the upper shell is provided with a light-shielding layer, a lower shell is installed at the bottom of the upper shell, a guide block is fixedly connected to the surface of the lower shell, an inductor coil is fixedly connected inside the lower shell, an LED bead is fixedly connected inside the lower shell, an induction antenna is fixedly connected to the outside of the inductor coil, a transmitting coil is fixedly connected to the top of the base, and a control module is fixedly connected to the top of the base.

[0006] Preferably, the upper shell is made of a light-transmitting material, and the light-shielding layer is made of a non-light-transmitting material.

[0007] Preferably, the light-shielding layer is obtained by removing the surface of the area to be illuminated through methods including but not limited to laser engraving.

[0008] Preferably, the connection method between the upper shell and the lower shell includes, but is not limited to, ultrasonic welding, snap-fitting, dripping, secondary injection molding, bonding, etc., and the mold gate positions of the upper shell and the lower shell are located on non-exterior surfaces.

[0009] Preferably, the transmitting coil is electrically connected to the control module, the LED bead is electrically connected to the inductor coil, and the control module is electrically connected to an external power supply.

[0010] Preferably, the guide block is U-shaped, and the inductor coil, the lamp bead and the induction antenna are all disposed on the inner side of the guide block.

[0011] Preferably, the planar gap at the point where the lower shell and the upper shell meet is less than 0.1 mm, and the flatness error between the bottom of the lower shell and the bottom of the upper shell is less than 0.1 mm.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 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, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 One embodiment provided by this utility model:

[0023] A non-contact controllable light-emitting game card includes an upper shell 1 and a base 3. The upper shell 1 has a light-shielding layer 11 on its surface. A lower shell 2 is mounted on the bottom of the upper shell 1. A guide block 21 is fixedly connected to the surface of the lower shell 2. An inductor coil 22 and an LED bead 23 are fixedly connected inside the lower shell 2. An induction antenna 24 is fixedly connected to the outside of the inductor coil 22. A transmitting coil 31 and a control module 32 are fixedly connected to the top of the base 3. The upper shell 1 and lower shell 2 are connected by ultrasonic welding, snap-fitting, dripping glue, secondary injection molding, and bonding, making assembly simple and cost-effective. The upper shell 1 and the lower shell 2 are installed together. From the bottom, the gap between the upper shell 1 and the lower shell 2 is within 0.1mm, and the flatness is ±0.1mm, which meets the level 8 flatness tolerance range. The surface effect of the tile is far superior to that of mahjong tiles produced by epoxy resin and polishing processes on the market. Assembly is time-saving and labor-saving, and the production cost is low as it does not require secondary injection molding. An inductor coil 22, an induction antenna 24 and a transmitting coil 31 are set. The upper shell 1 is moved above the base 3. The signal is transmitted to the control module 32 through the cooperation of the transmitting coil 31 and the induction antenna 24 to realize the induction reading function. Through the electromagnetic induction of the inductor coil 22, the light energy is provided to the LED bead 23 in a non-contact manner. Its display effect is better and it has game interaction function, making it more interesting.

[0024] Furthermore, the upper shell 1 is made of a light-transmitting material, while the light-shielding layer 11 is made of a non-light-transmitting material. When the LED bead 23 is lit, the light can pass through the upper shell 1 to the outside, while the light-shielding layer 11 will block the light. A non-light-guiding material is covered on the surface of the upper shell 1 as the light-shielding layer 11. The light-shielding layer 11 on the top of the upper shell 1 is removed by means including but not limited to laser engraving. The light passes through the removed light-shielding layer 11 and forms the desired pattern.

[0025] Furthermore, the light-shielding layer 11 is stripped of the surface of the area to be illuminated by means including but not limited to laser engraving. When the lamp bead 23 emits light, the stripped light-shielding layer 11 is transparent, while the light-shielding layer 11 that has not been stripped is opaque, thereby realizing the display of the pattern.

[0026] Further, the connection manner between the upper shell 1 and the lower shell 2 includes, but is not limited to, ultrasonic welding, snap fit, glue dispensing, overmolding, adhesion and the like. The mold gate positions of the upper shell 1 and the lower shell 2 are arranged on the non-appearance surface, and the gaps of the upper shell 1 and the lower shell 2 are arranged on the same plane, which facilitates minimizing the gap when the upper shell 1 and the lower shell 2 are closed, facilitates assembly and improves the yield. This design ensures no defects on the appearance surface, the appearance precision in mass production is at the 0.05mm level, and the precision and cost have significant advantages compared with the traditional mahjong glue dispensing and polishing process, which greatly improves the game handfeel experience. The connection through the above manner makes the assembly between the upper shell 1 and the lower shell 2 simple and low in cost.

[0027] Further, the transmitting coil 31 is electrically connected to the control module 32, the lamp bead 23 is electrically connected to the inductance coil 22, and the control module 32 is electrically connected to an external power supply. The cooperation of the transmitting coil 31 and the induction antenna 24 transmits a signal to the control module 32 to realize the induction reading function, and the electromagnetic induction of the inductance coil 22 provides energy for the lamp bead 23 to emit light in a non-contact manner.

[0028] Further, the guide block 21 is in a shape of a Chinese character "hui" (closed loop), and the inductance coil 22, the lamp bead 23 and the induction antenna 24 are all arranged on the inner side of the guide block 21. The guide block 21 blocks and guides the light, preventing the light from diverging to the surroundings, and the light is transmitted to the top of the upper shell 1 along the guide block 21. When the lamp bead 23 is lit, the pattern is viewed from the top of the upper shell 1, and the trace of the joint is not visible, so as to ensure the display effect of the card pattern surface and no obvious defect in appearance.

[0029] Further, the gap where the lower shell 2 contacts the bottom of the upper shell 1 is less than 0.1mm, and the flatness error of the bottom of the lower shell 2 and the bottom of the upper shell 1 is less than 0.1mm. The surface effect of the tile surface is far higher than that of mahjong tiles produced by the glue dispensing and polishing processes on the market, and combined with the transparent light conductivity of the material, the appearance effect is significantly improved, which greatly enhances the user experience during game and entertainment.

[0030] Working principle: In use, the upper shell 1 and the lower shell 2 are connected by means of ultrasonic welding, snap fit, glue dispensing, overmolding, adhesion and the like, which makes the assembly simple and low in cost, so that the upper shell 1 and the lower shell 2 are mounted to each other. Viewed from the bottom surface, the gap between the upper shell 1 and the lower shell 2 is within a certain range, and the flatness meets the tolerance value range of grade 8 flatness. The surface effect of the tile surface is far higher than that of mahjong tiles produced by the glue dispensing and polishing processes on the market. The upper shell 1 is moved above the base 3, the cooperation of the transmitting coil 31 and the induction antenna 24 transmits a signal to the control module 32 to realize the induction reading function, and the electromagnetic induction of the inductance coil 22 provides energy for the lamp bead 23 to emit light in a non-contact manner.

[0031] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
