[0052] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and accompanying drawings of this invention are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or accompanying drawings of this invention are used to distinguish different objects, not to describe a particular order.

[0053] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0054] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0055] See appendix Figures 1 to 7 This utility model proposes a projectile counting device, including a panel 1, a sensing module 2, and a counting module 3. The panel 1 has a receiving hole 100 for projectiles to pass through. The sensing module 2 is installed inside or near the receiving hole 100. The counting module 3 is electrically connected to the sensing module 2. When a projectile passes through the receiving hole 100, the sensing module 2 sends an electrical signal to the counting module 3, which then provides a hit notification to the user based on the signal.

[0056] In use, panel 1 is fixed in place, for example, tilted and supported on a flat surface such as a table or the ground. After the user picks up the object, they throw it. If the object passes through the receiving hole 100 on panel 1, the sensing module 2 sends an electrical signal to the counting module 3. The counting module 3 then notifies the user that the thrown object has hit the receiving hole 100. This hit notification can take the form of an audio prompt or a visual prompt, such as verbally announcing the number of hits / score, or displaying the number of hits / score on a display device. Simultaneously, the counting module 3 tallies the user's total number of successful throws.

[0057] Regarding the sensing module 2, in some embodiments, see Appendix Figures 2 to 4 The sensing module 2 includes a housing 21 and at least one sensing unit 22. The housing 21 is fixedly mounted on the bottom surface 101 of the panel 1 by screws, or the housing 21 is integrally formed with the panel 1. A housing cavity 210 is formed between the housing 21 and the panel 1, and the sensing unit 22 is located in the housing cavity 210. In addition, at least one sensing port 120 is provided on the housing 21 or the panel 1. The sensing port 120 connects the housing cavity 210 and the receiving hole 100. Each sensing unit 22 is provided with one sensing port 120. The sensing unit 22 identifies and senses the passage of a projectile into the receiving hole 100 through the sensing port 120.

[0058] Specifically, the sensing unit 22 is an infrared sensing probe or a sensing spring. For example, in some embodiments, see the attached drawing. Figure 4 The sensing unit 22 is an infrared sensing probe, and the sensing module 2 includes four infrared sensing probes. Four sensing ports 120 are correspondingly provided, equidistantly arranged around the receiving hole 100. The sensing parts of the infrared sensing probes protrude from the sensing ports 120, and all four infrared sensing probes point towards the center of the receiving hole 100. In other embodiments (not shown in the figure), for example, the sensing unit 22 is a sensing spring, and the sensing module 2 includes several sensing springs. The sensing ports 120 are set according to the number of sensing springs. Several sensing springs extend out of the sensing ports 120, and together they form a valve structure within the receiving hole 100. When a projectile passes through this valve structure, the sensing spring deforms, triggering the corresponding sensing spring.

[0059] In some embodiments, see Appendix Figure 3 and 4 The panel 1 includes a panel body 11 and a positioning edge 12. A receiving hole 100 is formed on the panel body 11, and the positioning edge 12 is arranged around the receiving hole 100. A sensing port 120 is formed on the positioning edge 12. The positioning edge 12 is used to limit the installation position of the sensing unit 22 and the housing 21 to prevent deviation in the installation position.

[0060] To enhance the enjoyment of the competition, in some embodiments, see the appendix. Figures 1 to 6 The panel 1 has at least two receiving holes 100, and the number of sensing modules 2 corresponds to at least two receiving holes 100. Each sensing module 2 is electrically connected to the same counting module 3. For example, if the two receiving holes 100 have different heights, different distances from the user, or different aperture sizes, the difficulty of hitting them with a throw will also be different. The counting module 3 will issue different prompts based on the different electrical signals it receives from the sensing modules 2. For example, in some embodiments, the two receiving holes 100 correspond to two different scores, and the counting module 3 has different counting multipliers corresponding to the electrical signals from the two sensing modules 2. For example, if the user hits a lower-scoring receiving hole 100, the counting module 3 will indicate that the user has obtained 20 points; if the user hits a higher-scoring receiving hole 100, the counting module 3 will indicate that the user has obtained 40 points.

[0061] Each sensing module 2 is connected to the same counting module 3, which can count the total score obtained by the user. Specifically, a wire passage 211 is formed between the housing 21 of each sensing module 2 and the bottom surface 101 of the panel 1. The wire passage 211 communicates with the housing 210 and extends towards the counting module 3. Each sensing unit 22 is electrically connected to the counting module 3 through a wire d, which passes through the wire passage 211. The wire passages 211 of each sensing module 2 are interconnected, and the wire passage 211 closest to the counting module 3 extends to the counting module 3 to minimize the exposure of the wire d and reduce safety risks.

[0062] Regarding the counting module 3, in some embodiments, visual images are used to prompt the user. Specifically, see the appendix. Figure 3 and Figure 7 The counting module 3 includes a housing 31, a control board 32, and a display unit 33. The housing 31 is mounted on the panel 1, specifically on the edge of the panel 1 or on the bottom surface 101 of the panel 1. The control board 32 and the display unit 33 are mounted on the housing 31, and both the sensing module 2 and the display unit 33 are electrically connected to the control board 32. The display unit 33 is partially exposed outside the housing 31, or the housing 31 is partially transparent corresponding to the display unit 33. The display unit 33 is used to display digital information of counting / scoring.

[0063] For example, in some embodiments, the outer casing 31 is detachably mounted on the edge of the panel 1, making it easier to store and transport. Specifically, the panel 1 includes a panel body 11 and a side edge 13 surrounding the panel body 11. A fitting groove 14 is formed on the side edge 13 along the thickness direction of the panel body 11. The outer casing 31 includes a shell body 311 and a fitting boss 312 formed on one side of the shell body 311. The fitting boss 312 can be inserted into the fitting groove 14 in an interference fit manner. The display unit 33 and the control board 32 are both mounted on the shell body 311. The shape of the shell body 311 can be designed in various ways, such as a cartoon shape resembling an animal head, thereby increasing the aesthetics of the throwing counting device. Specifically, the shell body 311 is assembled from an upper cover 3111 and a bottom cover 3112 by screws, forming a space between them for mounting the control board 32 and the display unit 33.

[0064] In some embodiments, see Appendix Figure 1 and 6 The projectile counting device also includes a front support leg 4 and a rear support leg 5. The front support leg 4 is located near the front side 1101 of the plate body 11, and the rear support leg 5 is located near the rear side 1102 of the plate body 11. The rear support leg 5 is longer than the front support leg 4, so that the rear side 1102 of the plate body 11 is higher than the front side 1101 of the plate body 11. The insertion slot 14 is located on the rear side 1102 of the plate body 11, so that the shell body 311 is located above the plate body 11. By opening one receiving hole 100 near the front side 1101 of the plate body 11 and another receiving hole 100 near the rear side 1102 of the plate body 11, two receiving holes 100 with different heights and distances can be obtained. The shell body 311 being located above the plate body 11 makes it easier for the user to view the digital information displayed by the display unit 33.

[0065] In some other embodiments (not shown in the figures), the housing 31 may also be fixedly mounted on the bottom surface 101 of the panel 1, and the upper surface of the panel 1 needs to have a through window through which the display unit 33 is exposed.

[0066] To enhance the user's enjoyment of throwing, in some embodiments, the counting module 3 further includes a timing unit 34, which is electrically connected to the control board 32. The display unit 33 is configured with a score display area 331 and a time display area 332. The score display area 331 displays the total score / total count of the user's throws, while the time display area 332 displays the time information calculated by the timing unit 34. Alternatively, two display units 33 can be configured to display time information and throw score information respectively. (See attached diagram) Figure 7 As shown, the shell body 311 adopts the shape of an animal head, with its two "eyes" being transparent and corresponding to the score display area 331 and the time display area 332, respectively.

[0067] To reduce the packaging and transportation costs of the projectile counting device and to facilitate storage, in some embodiments, see the appendix. Figure 2 , 5 6. Panel 1 includes a first support plate 15 and a second support plate 16. A front support leg 4 is detachably mounted on the first support plate 15, and a rear support leg 5 is detachably mounted on the second support plate 16. The first support plate 15 and the second support plate 16 are detachably connected or foldably connected to allow panel 1 to have a use state and a storage state. Specifically, when the first support plate 15 and the second support plate 16 are spliced ​​or unfolded into a complete plate-like object, panel 1 is in the use state; when the first support plate 15 and the second support plate 16 are separated from each other or folded, panel 1 is in the storage state, reducing the length of panel 1.

[0068] To prevent the first support plate 15 and the second support plate 16 from separating naturally when the panel 1 is in use, in some embodiments, the first support plate 15 includes a first plate body 151, a first limiting portion 152, a first rotating portion 153, and a first latching portion 154 formed on one side of the first plate body 151; the second support plate 16 includes a second plate body 161, a second limiting portion 162, a second rotating portion 163, and a second latching portion 164 formed on one side of the second plate body 161. The first rotating portion 153 and the second rotating portion 163 are rotatably connected so that the first plate body 151 and the second plate body 161 can be folded or unfolded towards each other.

[0069] Specifically, when the first panel 151 and the second panel 161 are unfolded to be flush, the first limiting part 152 and the second limiting part 162 abut against each other, simultaneously causing the first latching part 154 and the second latching part 164 to elastically engage, preventing the first panel 151 and the second panel 161 from continuing to move relative to each other, thereby fixing the panel 1 in the use state. Conversely, the user can apply external force to separate the first latching part 154 and the second latching part 164 from each other, and then drive the first panel 151 and the second panel 161 to fold together, thus restoring the panel 1 to the storage state.

[0070] Each of the first plate 151 and the second plate 161 has a receiving hole 100 and a sensing module 2 installed thereon. Both the first limiting part 152 and the second limiting part 162 have through holes 1500. When the panel 1 is in use, the wire passages 211 of the two sensing modules 2 are connected through these two through holes 1500, as shown in the attached figure. Figure 4 As shown.

[0071] Regarding the elastic fastening structure of the first latching part 154 and the second latching part 164, please refer to the appendix for details. Figure 5 and 6The first latching portion 154 includes a first hook 1541 and a first latching hole 1542 formed on the first limiting portion 152, and the second latching portion 164 includes a second hook 1641 and a second latching hole 1642 formed on the second limiting portion 162. When the first limiting portion 152 and the second limiting portion 162 abut against each other, the first hook 1541 elastically latches onto the second latching hole 1642, and the second hook 1641 elastically latches onto the first latching hole 1542. This double latching structure makes the connection between the first latching portion 154 and the second latching portion 164 more stable.

[0072] Furthermore, the first limiting part 152, the first plate body 151, and the side edge 13 connected to the first plate body 151 are integrally provided, as are the second limiting part 162, the second plate body 161, and the side edge 13 connected to the second plate body 161.

[0073] To further improve the stability of the connection between the first support plate 15 and the second support plate 16, and to prevent collapse at the joint between the first plate body 151 and the second plate body 161, in some embodiments, see the appendix. Figures 1 to 3 The projectile counting device also includes a reinforcing rod 6. The front end 601 of the reinforcing rod 6 is fitted onto the front support leg 4, and the rear end 602 of the reinforcing rod 6 is fitted onto the rear support leg 5. The reinforcing rod 6 abuts against the first support plate 15 and / or the second support plate 16 to consolidate the position of the first plate 151 and the second plate 161.

[0074] Also for the purpose of saving packaging and transportation costs and facilitating storage, in some embodiments, the reinforcing rod 6 includes a first rod body 61 and a second rod body 62. The first rod body 61 is connected to the front support leg 4, and the second rod body 62 is connected to the rear support leg 5, so that the first rod body 61 and the second rod body 62 are detachably connected. Specifically, they can be interlocked by an interference fit. When the first rod body 61 and the second rod body 62 are removed from each other, the total length of the reinforcing rod 6 is reduced, saving packaging and transportation costs and facilitating storage.

[0075] In addition, the counting module also includes a battery 35 and a switch 36. The battery 35 is installed inside the housing 31, and the switch is used to connect or disconnect the electrical connection between the battery 35 and the control board 32.

[0076] Obviously, the embodiments described above are only some embodiments of this utility model, not all embodiments. The accompanying drawings show preferred embodiments of this utility model, but do not limit the patent scope of this utility model. This utility model can be implemented in many different forms; rather, the purpose of providing these embodiments is to provide a more thorough and comprehensive understanding of the disclosure of this utility model. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing specific embodiments, or make equivalent substitutions for some of the technical features. Any equivalent structures made using the content of this utility model specification and drawings, directly or indirectly applied to other related technical fields, are similarly within the patent protection scope of this utility model.
