Description

Technical Field

[0001] The utility model relates to the technical field of entertainment equipment, in particular to a sensor plate for a dart target and a dart target. Background Art

[0002] Darts is a fun and competitive sport that can be easily played indoors and has gradually become an essential leisure activity for people. However, existing darts games typically rely on the user to determine where the dart lands on the target, resulting in slow scoring and prone to errors.

[0003] The utility model patent application number 202220299010.X discloses an automatic scoring device for hard darts, which includes a target board body, on which a partitioning assembly is provided. The partitioning assembly is used to divide the target board body into several throwing zones. Each throwing zone is provided with a sensing plate, on which a throwing plate for darts to be inserted is fitted. A pressure sensor is provided between the sensing plate and the target board body. A controller is provided outside the target board body. Several pressure sensors are electrically connected to the controller, and the controller is electrically connected to a scoring terminal. When a user throws a dart, the spiked end of the dart is inserted into the throwing plate. The sensing plate moves under the impact of the dart and contacts the pressure sensor. The pressure sensor and the controller transmit signals. The controller identifies the corresponding score based on the pressure sensors in different throwing zones and records the dart score in real time through the scoring terminal. Although this utility model patent can realize automatic scoring, it has the following problems: (1) Since a throwing board and a pressure sensor are arranged in alignment, when a dart is thrown at any position on a throwing board, the position recorded by the pressure sensor is consistent, and the accuracy of scoring is low; (2) The pressure sensor is arranged in alignment with the middle of the throwing board, and the area of ​​the throwing board is larger than the area of ​​the pressure sensor. When the dart is thrown at the edge of the throwing board, it may be impossible to score, and the sensitivity is low; (3) The sharp end of the dart needs to be inserted into the throwing board so that the sensing plate can move under the impact force of the dart and contact the pressure sensor. It is easy to cause damage after repeated use and has a short service life. Utility Model Content

[0004] The purpose of the utility model is to provide a sensor plate for a dartboard and a dartboard, aiming to improve the problems of low sensitivity and accuracy of scoring on existing dartboards, as well as short service life.

[0008] The second detection layer is provided with a conductive area and conductive wires having the same structure as the first detection layer, and the conductive wires of the second detection layer are electrically connected to the controller;

[0009] The insulating layer is provided with a through hole corresponding to the conductive area, and the thickness of the through hole forms a separation gap separating the conductive area of ​​the first detection layer and the conductive area of ​​the second detection layer.

[0010] Preferably, the connecting portion of the first detection layer and the connecting portion of the second detection layer are provided with a plug-in interface at the port.

[0011] Preferably, the plurality of conductive areas are distributed diffusely outwards with the center of the first detection layer as the target, and the distribution density of the conductive areas gradually decreases from the target outwards.

[0020] 2.

[0034] Example 1

[0035] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, the present embodiment provides a sensing plate for a dartboard, comprising a first detection layer 10, an insulating layer 11, and a second detection layer 12 stacked in sequence. The first detection layer 10 is provided with a plurality of conductive areas 101 and at least one conductive wire 102 electrically connecting the plurality of conductive areas 101. The conductive wire 102 extends outside the first detection layer 10 to form a connecting portion 1021. The connecting portion 1021 is electrically connected to the input end of a controller (not shown in the figure) to transmit an electrical signal. The controller may be a chip or a PLC (Chinese full name: programmable logic controller) or a single-chip microcomputer, such as a SDINBDG4-64G chip. The second detection layer 12 is provided with a conductive area and a conductive wire having the same structure as the first detection layer 10. The conductive wire of the second detection layer 12 is electrically connected to the controller (i.e., the conductive wire on the first detection layer 10). Multiple conductive areas 101 are aligned one by one with multiple conductive areas on the second detection layer 12); through holes 111 corresponding to the conductive areas 101 are provided on the insulating layer 11, and the thickness of the through holes 111 forms a separation gap separating the conductive areas 101 of the first detection layer 10 and the conductive areas of the second detection layer 12. When not in use, the conductive areas 101 of the first detection layer 10 and the conductive areas of the second detection layer 12 are separated by the insulating layer 11 to prevent the two from contacting and generating electrical signals; when a dart hits the sensor plate, the conductive areas 101 of the first detection layer 10 and the conductive areas of the second detection layer 12 can contact through the through holes 111 of the insulating layer 11 to generate electrical signals.

[0036] Specifically, multiple conductive areas 101 are arranged according to the score zones of the dart board. The overall structure of the sensing plate is light and thin. The first detection layer 10, the second detection layer 12 and the insulating layer 11 are thin film plate structures. In a preferred embodiment, the thickness of the first detection layer 10 is 0.105mm~0.305mm; the thickness of the second detection layer 12 is 0.105mm~0.305mm; the thickness of the insulating layer 11 is 0.155mm~0.285mm. The first detection layer 10 is used as a throwing surface. For example, when a dart hits the conductive area 101 of the first detection layer 10, the conductive area 101 of the first detection layer 10 moves due to the impact force, thereby contacting the conductive area of ​​the second detection layer 12 through the through hole 111 of the insulating layer 11. At this time, the conductive area 101 of the first detection layer 10 contacts the conductive area of ​​the second detection layer 12 to generate an electrical signal, and the electrical signal is transmitted to the controller through the conductive wire 102. The position coordinate information of each conductive area 101 is set in the controller, and the position coordinate of the dart hitting can be quickly obtained after receiving the electrical signal.

[0037] When the dart hits the non-conductive area 101, due to the thin overall structure of the sensing plate, it will drive the conductive areas 101 around the hit position to contact and generate electrical signals. At this time, it is a multi-point contact. Since the distance between the hit position and the surrounding conductive areas 101 is different, the time when the first detection layer 10 or the second detection layer 12 deforms is also different, and the conductive areas 101 at different positions are turned on at different speeds. After the surrounding conductive areas 101 transmit electrical signals to the controller through the conductive wires 102, the controller can obtain feedback signals with different time differences, so as to know the coordinates of the position where the dart hits, forming a high-precision and high-sensitivity scoring effect, which has good practicality.

[0038] Moreover, since the sensing plate of this embodiment has high sensitivity, it can sense and obtain the coordinates of the hit position as long as the impact force is generated by the dart hitting it, without the need for the dart to pierce the sensing plate. Therefore, it can be reused, is not prone to damage, has a long service life, and saves usage costs.

[0039] In this embodiment, the connection portion 1021 of the first detection layer 10 and the connection portion of the second detection layer 12 are provided with a plug interface (not shown in the figure) at the port, and can be electrically connected to the controller through the plug interface.

[0040] like Figure 1As shown, in this embodiment, multiple conductive areas 101 are distributed outward with the center of the first detection layer 10 as the center, and the distribution density of the conductive areas 101 gradually decreases from the center outward. Since the shape of the dartboard is usually circular, the different score zones on the dartboard can be concentric ring zones, or different zones can be formed by extending outward from the center in the shape of a fan. In order to ensure that the distribution area of ​​the conductive areas 101 in each zone is relatively uniform, thereby ensuring fairness, the distribution density of the conductive areas 101 gradually decreases from the center outward. The conductive areas on the second detection layer 12 are arranged in alignment with the conductive areas 101 on the first detection layer 10.

[0041] like Figure 3 As shown, in this embodiment, the conductive area 101 is formed by at least two connected conductive contacts 1011, preferably four connected conductive contacts 1011. The area of ​​each conductive area 101 can be adaptively adjusted according to the score division of the dartboard (i.e., the number of connected conductive contacts 1011 in different divisions is adjusted; the greater the number of connected conductive contacts 1011, the larger the area of ​​the formed conductive area 101). By adjusting the distribution density of the conductive areas 101 in different divisions, the distribution area of ​​the conductive areas 101 in each division can be further ensured to be relatively uniform.

[0042] In this embodiment, the conductive area 101 and conductive lines 102 are formed by printing conductive silver paste. Screen printing, flexographic printing, or offset printing can be used. The conductive silver paste can also be thick film paste or resin-based. The conductive area 101 and conductive lines 102 formed using conductive silver paste printing have the advantage of being lightweight, making the sensor board thinner and lighter overall.

[0043] In this embodiment, the first detection layer 10 and / or the second detection layer 12 and / or the insulating layer 11 are made of elastic material.

[0044] Specifically, the first detection layer 10 is used as a throwing surface. When a dart hits the first detection layer 10, the first detection layer 10 and the second detection layer 12 will compress or stretch the insulating layer 11 at the surrounding position. When the impact force disappears, the insulating layer 11 can provide a recovery force for the first detection layer 10 and the second detection layer 12. In addition, the first detection layer 10 and the second detection layer 12 themselves have a certain resilience and can be quickly separated and reset. In this way, the sensing plate can be used repeatedly, extending the service life of the sensing plate and having good practicality.

[0045] Furthermore, the material of the first detection layer 10 can be a film of PET (polyethylene terephthalate) material. PET material has good optical properties and weather resistance, as well as good creep resistance, fatigue resistance, and friction resistance. It has the highest toughness among thermoplastics, which can ensure the structural stability and service life of the first detection layer 10. The material of the second detection layer 12 can be a film of PC (polycarbonate) material, which has high strength, fatigue resistance, dimensional stability, and creep resistance, so that the second detection layer 12 has good structural stability and good practicality.

[0046] In this embodiment, the thickness of the second detection layer 12 is greater than that of the first detection layer 10. Preferably, the thickness of the first detection layer 10 can be 0.125 mm, the thickness of the second detection layer 12 can be 0.25 mm, and the thickness of the insulating layer 11 can be 0.188 mm. At the same time, the thickness of the conductive silver paste in the conductive area 101 on the first detection layer 10 and the second detection layer 12 can be 0.03 mm, which ensures conductivity while not affecting the thickness of the first detection layer 10 and the second detection layer 12 due to excessive thickness.

[0047] If the first detection layer 10 and the second detection layer 12 have the same thickness, production efficiency is higher and errors are less likely to occur during assembly. Alternatively, if the second detection layer 12 is thicker than the first detection layer 10, impact resistance can be improved, and differentiated installation can be performed, thereby improving practicality.

[0048] Example 2

[0049] A dartboard is also provided, comprising the sensor plate described in Example 1. The sensor plate can be mounted on a housing of the dartboard, and a dart score partitioning diagram can be attached to the surface of the sensor plate for ease of use. The dartboard can accurately and sensitively record the location of dart impacts, achieving rapid scoring, and is reusable, thus having excellent practicality.

[0050] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
