Description

Technical Field

[0001] The utility model relates to the field of sports flying discs, in particular to a flying disc and a flying disc assembly. Background Art

[0002] The sport of Frisbee is a fitness program suitable for all ages. It can be used for target throwing, two-person passing and catching exercises, and multi-player games and competitions. Sports Frisbees have been carefully designed to achieve reasonable flight performance for the shape, size, and weight of the disc. Particularly, team Frisbee is also known as Ultimate Frisbee. Because it is a competition event and enters various official national or international sporting events, each international or national Frisbee sports association has relatively clear standards and specifications for indicators such as the disc weight, size, and shape of the Ultimate Frisbee. Only Frisbees that meet the standards and specifications are recommended for use. The vast majority of professional, semi-professional, or outdoor Frisbee sports enthusiasts have generally used standard Ultimate Frisbees for entertainment, training, and competition.

[0003] Sports Frisbees with additional features, such as light-emitting Frisbees, can be used for practice and use in places with poor lighting and poor visibility, while sound-emitting Frisbees can bring a fresh and exciting experience to Frisbee entertainment, training, and competitions. However, these functional devices on the market take up a large amount of space and are installed in the middle of the Frisbee, between the flat portion of the disc and the rotation axis. This increases the thickness of the flat portion and the overall weight of the disc. To maintain a reasonable weight, the thickness of the curved edge of the disc must be reduced, which in turn reduces the centrifugal force (gyroscopic inertia) of the disc's rotation, inevitably weakening its stability. This makes it impossible to achieve the flight performance of a standard sports Frisbee, and in particular, it cannot be used as a standard ultimate Frisbee. Utility Model Content

[0004] The technical problem to be solved by the utility model is how to provide a passing sports Frisbee (such as an ultimate Frisbee) with a functional device.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: a flying disc, including a disc body, the disc body including a flat portion and a disc edge wall bend, the flat portion is disc-shaped, the disc edge wall bend is sleeved on the outside of the flat portion, and one end of the disc edge wall bend is fixedly connected to the flat portion or formed as one piece, and also includes a functional device, the functional device is embedded in the inner wall or outer wall of the disc edge wall bend, after the functional device is embedded, the center of mass of the disc body coincides with the rotation axis of the disc body.

[0006] The beneficial effects of the present invention are as follows: the flat portion and the rim bend constitute the structure of a standard transfer flying disc (such as a standard ultimate Frisbee), the functional device is embedded in the rim bend, and the rim bend after the additional function is substantially consistent with the inner and outer edge shapes of the rim bend of the standard transfer flying disc, so that the gripping and passing of the flying disc have the same object feeling as the standard transfer flying disc. Moreover, the flat portion is not provided with a functional device, retaining its original structure, thus avoiding increasing the gram weight of the flying disc and avoiding reducing the thickness of the rim bend in order to maintain a reasonable gram weight, thereby affecting the motion stability of the flying disc. The shape, gram weight and size of the flying disc of the present invention meet the basic requirements of a standard transfer flying disc. Not only does the weight of the disc body not increase, the proportion of the rim bend to the gram weight of the disc body does not change, the centrifugal force of the rotation of the flying disc does not decrease, the gyroscopic motion stability is good, and the flight performance of the standard transfer flying disc is achieved, especially it can be used as a standard transfer flying disc.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the functional device includes at least one auxiliary device, which is an electronic component or a non-electronic component.

[0009] The beneficial effect of adopting the above further scheme is that the functional device can realize the functions of luminescence, sound, flight motion data collection, identity recognition, display or communication through electronic components, or the functional device can realize the sound function through non-electronic components.

[0010] Furthermore, there are at least two auxiliary devices, and the masses of at least two auxiliary devices are the same and are evenly distributed along the circumference of the disc rim wall; or, the masses of at least two auxiliary devices are different and are unevenly distributed along the circumference of the disc rim wall.

[0011] The beneficial effect of adopting the above further solution is that, depending on the mass of the auxiliary devices, at least two auxiliary devices can be evenly or unevenly distributed, thereby achieving dynamic balance during the rotation of the flying disc. Furthermore, because the thickness of the rim bend of a standard passing flying disc is limited, when a single auxiliary device cannot meet performance requirements, a method of distributing multiple auxiliary devices or using multiple equally small auxiliary devices in a dispersed manner can be employed, each embedded within the inner or outer wall of the rim bend. The rim bend after adding the additional functions has substantially the same inner and outer edge shape as the rim bend of a standard passing flying disc, and the handling and passing of the flying disc provides the same physical feel as a standard passing flying disc.

[0012] Optionally, the functional device is an electronic intelligent device, which includes three auxiliary devices. The three auxiliary devices are unevenly distributed along the circumferential direction of the disk rim wall, and each auxiliary device includes one or more adjacently arranged basic units.

[0013] The beneficial effect of adopting the above optional solution is that the basic units are arranged in groups to form three auxiliary devices, which facilitates the arrangement of the auxiliary devices.

[0014] Optionally, the functional device is an electronic light-emitting device, which includes an auxiliary device and a light strip. The auxiliary device is a driving circuit module. The light strip is electrically connected to the driving circuit module. The driving circuit module is embedded in the inner wall of the disk edge wall bend, and the light strip is arranged circumferentially along the disk edge wall bend.

[0015] The beneficial effect of adopting the above optional solution is that in the electronic light-emitting device, the driving circuit module supplies power to the light strip and controls the lighting or extinguishing of the light strip. The light strip makes the flying disc illuminate, making the position of the flying disc clearly visible when used at night, and making it more aesthetically pleasing.

[0016] Furthermore, the electronic light-emitting device further comprises a plastic fiber filament which is in a ring shape and is sleeved on the outside of the light strip and is embedded in the outer side wall of the bend of the disk edge wall.

[0017] The beneficial effect of adopting the above further solution is that the plastic fiber filaments are sheathed on the outside of the light strip to guide light, so that the light emitted by the light strip is softer and more uniform.

[0018] Furthermore, one of the auxiliary devices includes a circuit module, a conductive electrode sheet and a circuit cover plate, the circuit module is fixedly connected to the circuit cover plate, the conductive electrode sheet is fixedly connected to the circuit cover plate, and is electrically connected to the circuit module.

[0019] The beneficial effect of adopting this further solution is that the circuit cover plate has a conductive electrode sheet. While the circuit cover plate covers and protects the circuit module, the conductive electrode sheet is also electrically connected to the circuit module. The conductive electrode sheet can be connected to external wires and transmit signals and data with the circuit module or charge the device. The conductive electrode sheet is a thin sheet structure, unlike conventional interfaces such as USB, which require a lot of space. The drive circuit module can be installed without changing the thickness of the plate edge wall bend.

[0020] Furthermore, one of the auxiliary devices also includes a toggle switch, which is electrically connected to the circuit module, and the length of the toggle switch rod extending outside the circuit cover is less than or equal to 1 mm.

[0021] The beneficial effects of adopting the above-mentioned further solution are as follows: The prior art typically uses touch switches or push switches. Touch switches require additional circuit design and device space, and push switches installed in the bend of the disc rim can be accidentally triggered while the disc is being held. Using a toggle switch, the lever is short and the exposed tip is minimal, allowing a fingernail to toggle and complete the switch circuit without affecting the grip during the disc transfer process. The toggle switch is small, lightweight, and stable, making it suitable for use in bends of disc rims of limited thickness. It does not add additional weight to a standard disc being passed, and similarly, the overall shape of the bend of the disc rim is unchanged.

[0022] Optionally, the functional device is a non-electronic sound-emitting device, and the non-electronic sound-emitting device has at least two auxiliary devices, the auxiliary device being a whistle module, the whistle module including a sound cavity and a whistle mouthpiece, the sound cavity being opened in the bend of the disk edge wall, the outer side wall of the bend of the disk edge wall being opened with a whistle mouthpiece mounting hole connected to the sound cavity, and the whistle mouthpiece is detachably connected to the whistle mouthpiece mounting hole.

[0023] The beneficial effect of adopting the above optional solution is that during the flight of the flying disc, air passes through the whistle piece, and the sound cavity and the whistle piece cooperate to produce sound.

[0024] Furthermore, the edge of the plate is provided with a weight compensation slot; and / or the edge of the plate has a thickened portion formed integrally therewith.

[0025] The beneficial effect of adopting this further solution is that if the weight of the flying disc exceeds the standard weight of a catching flying disc after adding the functional device, a weight compensation slot is provided to reduce the weight, ensuring that the weight compensation slot does not affect the dynamic balance of the disc body when rotating about the central axis. If the overall weight of the flying disc is reduced, the thickness of the rim wall is appropriately increased by providing a thickened portion to bring the weight of the flying disc into compliance with the standard weight of a catching flying disc.

[0026] Furthermore, the weight, size and shape of the flying disc meet the requirements of a standard flying disc.

[0027] The utility model also provides a flying disc assembly, including a contact device and a flying disc, wherein the contact device includes a spring clip and a clamping conductive electrode sheet, the clamping conductive electrode sheet is fixedly connected to the spring clip and abuts against the conductive electrode sheet for conduction or separation.

[0028] The beneficial effect is that the spring clip can be directly clamped onto the disc rim bend, allowing the conductive electrode at the clamp opening to abut against the conductive electrode on the disc's annular bend, thereby transmitting signals, data, or charging. This conductive electrode-spring clip pairing eliminates the need for a connector, significantly reducing the additional size and weight of the functional device. It also eliminates the impact of the connector opening on the disc rim bend shape, more closely conforming to the standard transmission disc rim bend shape. BRIEF DESCRIPTION OF THE DRAWINGS

[0072] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0073] Example 1

[0074] Flying disc is a type of sport Frisbee. Flying disc includes standard flying disc, which includes standard ultimate Frisbee. Figure 1-Figure 3The diagram shows a standard flying disc being passed. The flat portion 10 and the curved edge 11 form the structure of a standard flying disc. One end of the curved edge 11 curves radially inward, forming an arc. This arc smoothly connects to the edge of the flat portion 10. In addition to overcoming air resistance during flight, the curved edge 11 also effectively mitigates impacts on the palm of the hand when handling the disc, particularly when grasping or blocking a high-speed flying disc.

[0075] The flat portion 10 and the concave inner wall 111 of the disc rim bend 11 form a space, which generates aerodynamic force during flight, maintains the flight altitude, and increases the forward distance.

[0076] The flat portion 10 of the disk body 1 has a typical thin-wall feature, and the thickest part of the disk edge wall bend 11 is several times thicker than the flat portion 10. The mass of the disk edge wall bend 11 accounts for most of the overall mass of the disk body 1, generating more rotational centripetal force, or so-called gyroscopic effect, making the disk body 1 stable and not prone to tilting during high-speed flight.

[0077] like Figure 4-Figure 36 As shown, this embodiment provides a flying disc, including a disc body 1, which includes a flat portion 10 and a disc edge wall bend 11. The flat portion 10 is disc-shaped, and the disc edge wall bend 11 is sleeved on the outside of the flat portion 10, and one end of the disc edge bend 11 is fixedly connected to the flat portion 10 or integrally formed. The disc body 1 also includes a functional device 12, which is embedded in the inner wall 111 or the outer wall 112 of the disc edge wall bend 11. After the functional device 12 is embedded, the center of mass of the disc body 1 coincides with the rotation axis of the disc body 1.

[0078] Based on the standard flying disc passing, such as Figure 4-Figure 36 As shown, the functional device 12 is embedded in the disc rim bend 11. The disc rim bend 11 after the additional function is substantially identical in shape to the disc rim bend 11 of the standard passing flying disc, so that the grip and passing of the flying disc have the same object feeling as the standard passing flying disc. Moreover, the flat portion 10 is not provided with the functional device 12, retaining its original structure, thereby avoiding increasing the weight of the flying disc and avoiding reducing the thickness of the disc rim bend 11 to maintain a reasonable weight, thereby affecting the motion stability of the flying disc. The flying disc of the utility model is provided with the functional device 12, enriching the functionality of the flying disc, and the shape, weight and size of the flying disc meet the basic requirements of the standard passing flying disc. Not only does the weight of the disc body 1 not increase, the proportion of the disc rim bend 11 to the weight of the disc body 1 does not change, the centrifugal force of the flying disc is not reduced, the gyroscopic motion stability is good, and the flight performance of the standard sports flying disc is achieved, especially it can be used as a standard passing flying disc.

[0079] On the basis of the above solution, the functional device 12 includes at least one auxiliary device 13 , which is an electronic component or a non-electronic component.

[0080] The functional device 12 can realize the functions of luminescence, sound generation, flight motion data collection, identity recognition, display or communication through electronic components, or the functional device 12 can realize the sound generation function through non-electronic components.

[0081] Based on the above scheme, there are at least two auxiliary devices 13, and the masses of at least two auxiliary devices 13 are the same and are evenly distributed along the circumference of the disk rim wall bend 11; or, the masses of at least two auxiliary devices 13 are different and are unevenly distributed along the circumference of the disk rim wall bend 11.

[0082] Depending on the mass of the auxiliary devices 13, at least two auxiliary devices 13 can be evenly or unevenly distributed, thereby achieving dynamic balance during the rotation of the flying disc. Furthermore, because the thickness of the rim bend 11 of a standard passing flying disc is limited, if a single auxiliary device 13 cannot meet performance requirements, a plurality of auxiliary devices 13 can be dispersed, or a plurality of equally small auxiliary devices 13 can be dispersed and used, each embedded within the inner sidewall 111 or outer sidewall 112 of the rim bend 11. The rim bend 11 with the added function has substantially the same inner and outer edge shape as the rim bend 11 of a standard passing flying disc, providing a consistent feel when gripping and passing the flying disc.

[0083] Specifically, such as Figure 22 As shown, the disc edge wall bend 11 is provided with a device embedding slot 15 , and the auxiliary device 13 is embedded in the corresponding device embedding slot 15 .

[0084] On the basis of the above scheme, in order to meet the gram weight requirements of the standard flying disc, a gram weight compensation slot 16 is opened in the central interior of the disc edge wall bend 11; and / or the disc edge wall bend 11 also has a thickened portion integrally formed therewith.

[0085] Thus, if the weight of the flying disc exceeds the standard weight of a transfer flying disc after adding functional device 12, weight compensation slots 16 are provided to reduce the weight, ensuring that weight compensation slots 16 do not affect the dynamic balance of disc body 1 when rotating about central axis 100. If the overall weight of the flying disc is reduced, the weight of the flying disc can be brought into compliance with the standard weight of a transfer flying disc by providing a thickened portion, that is, by appropriately increasing the thickness of the disc rim bend. The thickened portion is integrally formed with the disc rim bend 11.

[0086] Optionally, the gram weight compensation slot 16 is an annular hole arranged circumferentially along the rim wall bend 11, or there are multiple gram weight compensation slots 16, and the multiple gram weight compensation slots 16 are evenly distributed along the circumference of the rim wall bend 11, and the gram weight compensation slot 16 is a groove opened in the inner wall 111, or a hole opened in the rim wall bend 11.

[0087] Among them, in order to ensure that the center of mass of the disk body coincides with the rotation axis of the disk body after the functional device 12 is embedded, when the functional device 12 includes an auxiliary device 13, the method of making the gram weight of the auxiliary device 13 equal to the gram weight of the disk body 1 material of the same volume as the device embedded in the slot 15 can be adopted; when the functional device 12 includes two or more auxiliary devices 13, the corresponding rotational dynamic balance can also be obtained by setting a gram weight compensation slot 16 to subtract the gram weight of the material, or thickening the disk edge wall bend 11 to increase the gram weight.

[0088] Optionally, the weight, size, and shape of the disc conform to the requirements of a standard passing disc.

[0089] The standard passing Frisbee (or standard passing sports Frisbee) mentioned in the present invention includes a team Frisbee, also known as Ultimate Frisbee, or a standard Ultimate Frisbee, which is a standard Ultimate Frisbee used by Frisbee sports management organizations such as the World Frisbee Federation (WFDF), the United States Ultimate Frisbee Association (USA Ultimate), and the General Administration of Sport of China. The standard means that the disc body 1 of the Frisbee should meet the basic regulations of its corresponding shape, weight and size; these regulations include the currently used adult standard Ultimate Frisbee (such as a gram weight of 175g±3g, a diameter of 274mm±3mm, and a thickness of 32mm±2mm), and the youth (U12) standard Ultimate Frisbee (such as a gram weight of 145g±3g, a diameter of 249mm±5mm, and a thickness of 33mm±2mm). Of course, the Frisbee of this solution can also adopt the gram weight, diameter and thickness required by other standards. This solution can add additional functional devices while meeting the specifications of these standard categories.

[0090] Example 2

[0091] On the basis of the first embodiment, the flying disc of this embodiment is an electronic intelligent flying disc. Figure 4-Figure 8 、 Figure 21-23 As shown, the functional device 12 is an electronic intelligent device 121, which includes three auxiliary devices 13. The three auxiliary devices 13 are unevenly distributed along the circumference of the disk rim wall bend 11, and each auxiliary device 13 includes one or more adjacent basic units.

[0092] In this solution, the basic units are grouped to form three auxiliary devices, which facilitates the arrangement of the auxiliary devices.

[0093] The electronic intelligent device 121 may be a combination of any basic units (electrical components).

[0094] In one specific example, the electronic intelligent device 121 is an electronic intelligent device with a sound-generating function. The three auxiliary devices 13 are a sound-generating driving device, a power supply module 132, and an MPU sensor module 133. The sound-generating driving device includes a driving circuit module 131 and a sound output module 134. The sound output module 134 is arranged side by side and fixedly connected to the driving circuit module 131. The power supply module 132, the MPU sensor module 133, and the sound output module 134 are all electrically connected to the driving circuit module 131.

[0095] In the electronic intelligent device 121, the driver circuit module 131 is used to control the start and stop of power supply and sound generation. The power supply module 132 supplies power to the MPU sensor module 133 and the sound output module 134 through the driver circuit module 131. The MPU sensor module 133 can be equipped with required sensors to collect corresponding data, such as a speed sensor to collect the rotational speed of the flying disc. The sound output module 134 is used to generate sounds to increase the functionality, utility, or enjoyment of the flying disc.

[0096] Specifically, the driving circuit module 131 includes a charge and discharge protection circuit and an audio amplifier circuit.

[0097] Specifically, the power supply module 132 includes a plurality of connected lithium batteries and a power supply control circuit module (including functions such as charge and discharge protection, voltage and current adjustment, etc.). In one specific example, the power supply module 132 includes two lithium batteries.

[0098] Specifically, the MPU sensor module 133 comprises an interconnected MPU module and sensor module. The MPU sensor module 133 enables wireless communication, transmitting sensor data to an electronic terminal for convenient viewing of information such as the disc's motion status. The sensor module transmits rotational flight status signals or data to the MPU module, which determines the disc's flight status and degree of rotation based on these signals or data. The MPU module then transmits an audio signal to the driver circuit module 131, causing the sound output module 134 to emit different tones.

[0099] The installation positions of the plurality of auxiliary devices 13 of the present invention on the plate edge wall bend 11 need to be determined by centroid calculation. Taking the electronic intelligent device 121 of this embodiment as an example, the calculation method is as follows:

[0100] like Figure 7 As shown, because the three sets of independently positioned auxiliary devices 13 have different weights, in order to achieve rotational dynamic balance of the entire disk body 1, the three sets of auxiliary devices 13 cannot be evenly arranged on the disk rim wall curve 11. The center of mass needs to be calculated according to the following equation. Dynamic balance can be achieved when the center of mass coincides with the central axis 100 of the disk body 1:

[0101] M1 Cos(a)+M2 Cos(b)=M0;

[0102] M1 S in(a)=M2 S in(b);

[0103] In the formula, M0, M1, and M2 represent the masses of the three auxiliary devices 13, respectively. M0 is the mass of the auxiliary device 13 with the largest mass and is defined as 1. The center of the disk 1 is used as the origin of the coordinate system, and the center of gravity of the auxiliary device 13 with the largest mass coincides with the negative half-axis of the X axis. M1 and M2 are both normalized to M0, and the sum of M1 and M2 must be greater than 1 (normalization rule). a and b represent the angles between M1 and M2 and the positive direction of the X axis, respectively, and are between 0 and 90 degrees. The specific values of a and b need to be solved by the formula.

[0104] In one specific embodiment, the following table shows the weights of three independently positioned auxiliary devices 13: M0 represents the mass of the power supply module 132, M1 represents the mass of the sound drive device, and M2 represents the mass of the MPU sensor module 133. It should be noted that the effective weight increase is the mass of the auxiliary device 13 minus the mass of the frisbee material of equal volume. It should be noted that the data in the table is only used to illustrate the center of mass calculation process and is not intended to limit the mass of each auxiliary device 13.

[0105]

[0106] The calculated results are a = 69.75° and b = 11.5°. Enter these values into 3D drawing software (such as SOLIDWORKS) to plot the slot positions for the three functional modules. Add the module components to the assembly drawing (the material masses of each module must be specified). You should see that the center of mass of the disk body 1 and the central axis 100 are essentially aligned. If there are any errors, fine-tune angles a or b and recheck the assembly drawing. Repeat this process until the ideal alignment and positioning of the auxiliary device 13 are achieved.

[0107] These auxiliary devices 13 all meet the requirements of the wall thickness of the rim wall bend 11. Their combination follows the normalization rules of M0, M1 and M2. In principle, the three auxiliary devices 13 are the basic method to achieve dynamic balance. Two components with different masses cannot achieve dynamic balance on a circle with the same radius. In other words, if an even number of auxiliary devices 13 achieve dynamic balance on the same circumference, the masses of the two must be equal (unless additional weight compensation slots 16 are added separately inside the rim wall bend 11 to offset the excess weight of the components with larger mass). In practical applications, it is difficult to achieve completely different electronic modules of equal mass. Therefore, in this embodiment, the sound output module 134 and the drive circuit module 131 are arranged side by side to form a sound driving device, two lithium batteries form the power supply module 132, and the MPU module and the sensor module form the MPU sensor module 133. In this way, the six modules are paired in pairs to form three groups, so that the above formula can be used to calculate and achieve rotational dynamic balance.

[0108] Specifically, such as Figure 8 As shown, in this embodiment, the weight compensation slot 16 is a wiring slot 161. The wiring slot 161 is opened on the side of the auxiliary device 13 facing the outer wall 112. This is because the average mass density of each auxiliary device 13 of the electronic intelligent device 121 is 1.26, which is different from the mass density of the disk body 1 of 0.92. After being embedded, it generates additional weight. The opening of the hidden wiring slot 161 can reduce the additional weight, so that the overall weight of the flying disc meets the requirements of the standard transmission flying disc. At the same time, the wiring slot 161 is set as a ring that runs circumferentially along the rim wall bend 11 of the disk. The wiring slot 161 can be used to arrange wires. The auxiliary devices 13 are electrically connected through internal wiring. Because the wiring slot 161 is arranged in a ring, it will not affect the rotational dynamic balance of the disk body 1.

[0109] The electronic intelligent flying disc of this embodiment has three sets of independently positioned auxiliary devices 13 embedded in the disc rim wall curve 11 (one set of two lithium batteries, one set of an MPU module and a sensor module, and one set of a drive circuit module 131 and a sound output module 134). These are arranged circumferentially along the disc body 1 and their installation positions are determined through rigorous calculations to ensure the rotational dynamic balance of the disc body 1, avoid adding any functional devices and their auxiliary devices to the flat portion 10 of the disc body 1, retain its thin-wall characteristics, and meet the standard requirements for the weight, size, and shape of standard hand-held flying discs. This embodiment is not available in existing technologies related to flying discs with additional sound functions.

[0110] Example 3

[0111] Based on the first embodiment, Figures 9-20As shown, the functional device 12 is an electronic light-emitting device 122, which includes an auxiliary device 13 and a light strip 135. The auxiliary device 13 is a driving circuit module 131. The light strip 135 is electrically connected to the driving circuit module 131. The driving circuit module 131 is embedded in the inner wall 111 of the disk rim wall bend 11, and the light strip 135 is arranged circumferentially along the disk rim wall bend 11.

[0112] In the electronic light emitting device 122, the driving circuit module 131 supplies power to the light strip 135 and controls the lighting or extinguishing of the light strip 135. The light strip 135 makes the flying disc illuminate, and when the flying disc is used at night, the position of the flying disc is clearly visible and more beautiful.

[0113] Optionally, the driving circuit module 131 of this embodiment has its own battery for power supply; or an independent power supply module 132 is provided to be electrically connected to the driving circuit module 131 .

[0114] Specifically, in this embodiment, the device embedding slot 15 includes a drive circuit embedding slot 151 and a light strip embedding slot 152. The inner sidewall 111 defines a drive circuit embedding slot 151. The number of drive circuit embedding slots 151 is the same as the number of drive circuit modules 131. The drive circuit modules 131 are embedded in the corresponding drive circuit embedding slots 151. The light strip embedding slot 152 is an annular groove, defined within the outer sidewall 112 or within the bend of the rim 11. The light strip 135 is embedded within the light strip embedding slot 152.

[0115] In one specific example, the light strip 135 is connected to the driving circuit module 131 to form a light strip assembly. There are multiple light strip assemblies, and the multiple light strip assemblies are arranged in rotational symmetry around the central axis 100 of the disk body 1. The multiple light strip assemblies are arranged in rotational symmetry around the central axis 100, which does not affect the dynamic balance of the rotation of the disk body 1.

[0116] In another example, the light strip 135 is annular, or multiple light strips 135 are arranged in rotational symmetry around the central axis 100, there are one or more driving circuit modules 131 and power supply modules 132, and their arrangement positions on the circumference are calculated according to the center of mass calculation method of Example 2.

[0117] Example 4

[0118] Based on the third embodiment, Figures 9-14 、 Figure 21-23 As shown, the flying disc of this embodiment is an outer groove type electronic light-emitting flying disc, and the electronic light-emitting device 122 also includes a plastic fiber filament 136. The plastic fiber filament 136 is annular and is sleeved on the outside of the light strip 135. The plastic fiber filament 136 is embedded in the outer wall 112 of the disc edge wall bend 11.

[0119] The plastic fiber filaments 136 are sleeved on the outside of the light strip 135 to guide light, so that the light emitted by the light strip 135 is softer and more uniform.

[0120] In one specific example, Figure 11 As shown, there are two light strip assemblies, which are arranged in rotational symmetry around the central axis 100, thus achieving rotational dynamic balance of the disk body 1.

[0121] The light strip embedding groove 152 is opened on the outer wall 112, and the two light strips 135 are embedded in the light strip embedding groove 152 and form a ring. The plastic fiber filament 136 is sleeved on the outside of the light strip 135 and is located in the light strip embedding groove 152. The plastic fiber filament 136 is annular and will not affect the rotational balance of the entire disk body 1.

[0122] In this embodiment, the average mass density of the driving circuit module 131, the light strip 135 and the plastic fiber filament 136 is greater than the mass density of the disk body 1. In order to embed these devices, the weight of the material lost by the device embedding slot 15 opened in the disk body 1 is still less than the weight of these devices. Therefore, intermittent weight compensation slots 16 are opened in the light strip embedding slot 152 of the outer wall 112, such as Figure 13 As shown, the intermittent weight compensation slots 16 are not only hidden behind the light strip 135, but also provide support for the light strip 135. By appropriately adjusting the length of each weight compensation slot 16 according to the increase in weight, the excess weight introduced by these devices can be accurately subtracted. Because the weight compensation slots 16 are distributed symmetrically along the center of the disc rim 11, they do not affect the rotational balance of the entire disc body 1.

[0123] It's worth noting that this embodiment utilizes two light strip assemblies, with the length of light strip 135 being half the circumference of the flying disc. In future product designs, shortening the length of light strip 135 can reduce power consumption, extend the lighting duration, or increase brightness at the same driving voltage. Therefore, depending on different requirements, one could try using a single full-circumference light strip 135 and one driver circuit module 131, or four quarter-circumference light strips 135 and four driver circuit modules 131, or even more light strips 135 and driver circuit modules 131, to achieve the desired luminous durability or brightness. Similarly, as long as the light strip assemblies are arranged rotationally symmetrically around the central axis 100 on the disc rim bend 11, the rotational balance of the entire disc body 1 will not be affected.

[0124] The external-slot electronic light-emitting disc of this embodiment lacks any auxiliary devices, such as a power supply, driver module, connectors, or switching circuits, on its flat portion 10, retaining the thin-walled characteristics of a standard transfer disc. The electronic light-emitting devices 122 required for illumination are rotationally symmetrically arranged and embedded within the disc's rim curve 11, with a thickness similar to that of the disc's rim curve 11. This ensures rotational dynamic balance and meets the basic specifications for standard transfer discs in terms of weight, size, and shape. This solution can even be manually fabricated using existing standard transfer discs, a feat difficult to achieve with existing light-emitting disc technology.

[0125] Example 5

[0126] On the basis of the third or fourth embodiment, Figures 15-20 、 Figure 21-23 As shown, the flying disc of this embodiment is an inner groove type electronic light-emitting flying disc, which is different from the fourth embodiment in the installation method of the electronic light-emitting device 122.

[0127] In this embodiment, the edge wall bend 11 is split into a wall bend body and a wall bend buckle 113 along the axial direction. The wall bend body is integrally formed with the flat portion 10. A light strip embedding groove 152 is provided on the end surface of the wall bend body. Figure 18 As shown, during assembly, the light strip assembly is first installed into the driving circuit embedding groove 151 and the light strip embedding groove 152, and then the wall bend buckle 113 is fastened and fixed to the wall bend body.

[0128] The flying disc of this embodiment is more suitable for injection molding, resulting in lower manufacturing costs, a feature not available in existing light-emitting flying discs. Specifically, the edge curve 11 of the disc is made of a translucent material where the light strip 135 is located. Compared to using fully transparent material, the translucent material makes the light strip 135 appear softer and the light spots appear continuous.

[0129] In this embodiment, the light strip embedding groove 152 in the bend of the plate edge wall 11 is also a slot for weight compensation. It is hidden in the bend of the plate edge wall 11 and is in a continuous ring shape. Since the average mass density of the light strip assembly is greater than the mass density of the plate body 1, the weight of the material lost by the light strip embedding groove 152 opened in the plate body 1 to embed the light strip assembly is still less than the weight of these devices. The light strip embedding groove 152 in the bend of the plate edge wall 11 can reduce the excess weight brought by the light strip assembly. Figure 20 As shown, the width of the light strip embedding groove 152 is much larger than that of the light strip 135, thereby compensating for the extra weight. The light strip embedding groove 152 is set in an annular shape and will not affect the rotational balance of the entire disk body 1.

[0130] Example 6

[0131] On the basis of any one of the second to fifth embodiments, as Figure 21-23As shown, one of the auxiliary devices 13 includes a circuit module 1311 , a conductive electrode sheet 1312 and a circuit cover 1313 . The circuit module 1311 is fixedly connected to the circuit cover 1313 . The conductive electrode sheet 1312 is fixedly connected to the circuit cover 1313 and is electrically connected to the circuit module 1311 .

[0132] Circuit cover 1313 includes a conductive electrode sheet 1312. While covering and protecting circuit module 1311, conductive electrode sheet 1312 is also electrically connected to circuit module 1311. This allows connection to external wires, signal and data transmission with circuit module 1311, and charging of the battery in power supply module 132 or driver circuit module 131 via circuit module 1311. Conductive electrode sheet 1312 is a thin sheet-like structure, unlike conventional interfaces like USB, which require significant space. Driver circuit module 131 can be installed without altering the thickness of the bend 11.

[0133] Optionally, the circuit cover 1313 is a separately added plate-like component; or, the circuit cover 1313 is the circuit substrate of the circuit module 1311 (i.e., a double-layer circuit board structure), the circuit substrate is used as the circuit cover 1313, the conductive electrode 1312 is on one side of the circuit cover 1313, and the circuit module 1311 is made on the other side of the cover 1313, and the electronic circuit on the circuit module 1311 is installed toward the disk edge wall bend 11 and hidden in the device embedding slot 15.

[0134] One of the auxiliary devices 13 mentioned in this embodiment is any auxiliary device 13 with an electronic circuit, such as a driving circuit module 131 , a power supply module 132 or an MPU sensor module 133 .

[0135] Based on the above solution, the driving circuit module 131 further includes a toggle switch 137 , which is electrically connected to the circuit module 1311 . The length of the toggle switch 137 extending out of the circuit cover 1313 is less than or equal to 1 mm.

[0136] Conventional technology typically uses touch switches or push switches. Touch switches require additional circuit design and device space, while push switches installed on the disc rim bend 11 can be accidentally triggered while the disc is being held. The toggle switch 137, with its short lever and short protrusion, can be toggled by a fingernail to complete the switch circuit without affecting the grip during disc transfer. The toggle switch is compact, lightweight, and stable, making it suitable for use in disc rim bends 11 of limited thickness. It does not add additional weight to a standard disc and does not alter the overall shape of the disc rim bend 11.

[0137] Example 7

[0138] On the basis of the first embodiment, the flying disc of this embodiment is a sound cavity sounding flying disc, such as Figures 27-36 As shown, the functional device 12 is a non-electronic sound-generating device 123, and the non-electronic sound-generating device 123 has at least two auxiliary devices 13. The auxiliary device 13 is a whistle module. The whistle module includes a sound cavity 138 and a whistle mouthpiece 139. The sound cavity 138 is opened in the rim wall bend 11, and the outer wall 112 of the rim wall bend 11 is provided with a whistle mounting hole connected to the sound cavity 138. The whistle mouthpiece 139 is detachably connected to the whistle mounting hole.

[0139] During the flying disc's flight, air passes through the whistle piece 139 , and the sound cavity 138 and the whistle piece 139 cooperate to produce sound.

[0140] Optionally, the whistle mouth pieces 139 of at least two whistle modules face the same side along the circumference of the rim wall bend 11; or, the whistle mouth pieces 139 of at least two whistle modules include at least one left whistle mouth 1390 and at least one right whistle mouth 1391, such as Figure 29 、 Figure 30 and Figure 33 As shown, the left whistle opening 1390 and the right whistle opening 1391 are oriented in opposite directions. For example, the left whistle opening 1390 faces counterclockwise relative to the bend 11 of the disc rim, while the right whistle opening 1391 faces clockwise relative to the bend 11 of the disc rim. This allows the disc to emit sound when rotating forward or backward. Specifically, at least one left whistle opening 1390 and at least one right whistle opening 1391 are alternately positioned along the bend 11 of the disc rim.

[0141] Specifically, such as Figure 31 and Figure 32 As shown, the whistle mouthpiece 139 is designed with a narrow, oblique opening. When the disc rotates, air flows through the oblique opening into the sound cavity 138. When the airflow is strong enough, it oscillates in the sound cavity 138, producing a whistle sound. The timbre of the whistle is determined by the shape and size of the sound cavity 138; a smaller sound cavity 138 results in a higher pitch. This allows the production of whistle discs with different timbres. At the same flight speed, increasing the number of whistle modules can increase the sound intensity.

[0142] like Figure 33 As shown, the whistle modules are evenly distributed along the circumference of the disc rim 11, ensuring rotational balance of the disc body 1. Adjusting the thickness of the disc rim 11 can compensate for the weight loss of the cavity, while still achieving the standard weight of a standard ultimate Frisbee (e.g., 175g). The flat portion 10 of the disc retains its thin-walled characteristics without any other auxiliary devices.

[0143] Optionally, the sound cavity 138 is a cylindrical cavity, and the cylindrical cavity 138 can produce a mellow whistle sound. Figure 27 and Figure 28As shown, the sound cavity 138 is located in the bend 11 of the disc edge wall. The inner wall 111 of the bend 11 is flat, which provides a consistent grip and is close to the standard flying disc. In another sound cavity sounding flying disc, Figure 29 and Figure 30 As shown, the sound cavity 138 is independently disposed on the inner sidewall 111 of the disc rim bend 11; and the whistle piece 139 of this embodiment is designed at the corner of the disc rim bend 11, that is, the upper edge of the outer sidewall 112 of the disc rim bend 11. When the flying disc touches the ground or falls, it is usually the lower edge of the outer sidewall 112 of the disc rim bend 11 that touches the ground. This design effectively prevents the whistle piece 139 from being damaged when the disc touches the ground, thereby extending the service life of the disc. Although the appearance of some sound cavity sounding discs does not meet the requirements of standard passing discs, the weight and external dimensions can meet the requirements of standard passing discs.

[0144] Optional, such as Figure 34 As shown, the sound cavity 138 is a flat tubular shape, capable of producing a sharper whistle than a cylindrical cavity. Furthermore, the sound cavity 138 is completely concealed within the bend 11 of the disc rim, making the inner and outer walls of the bend 11 more consistent with the shape of a standard passing disc. This embodiment can be used as a standard passing disc with an additional sound function.

[0145] Further, such as Figure 35 and Figure 36 As shown, the sound cavity 138 is a flat tubular shape that produces a sharp whistle sound. Furthermore, the whistle piece 139 is located at the corner of the rim wall bend 11, that is, at the upper edge of the outer wall 112 of the rim wall bend 11. This effectively prevents the whistle piece 139 from being damaged when the disc touches the ground, thereby extending the service life of the disc. The sound cavity 138 can be independently located on the inner edge of the rim wall bend 11, or the bend of the rim wall bend 11 can be thickened to house the sound cavity 138 within it.

[0146] Example 8

[0147] Based on Example 6, Figure 24-26 As shown, this embodiment also provides a flying disc assembly, including a contact device 14 and a flying disc, the contact device 14 includes a spring clip 140 and a clamping conductive electrode sheet 141, the clamping conductive electrode sheet 141 is fixedly connected to the spring clip 140, and abuts against the conductive electrode sheet 1312 for conduction or separation.

[0148] Spring clip 140 can be directly clamped onto the disc rim bend 11, allowing conductive electrode 141 to contact conductive electrode 1312, thereby transmitting signals, data, or charging. This method of pairing conductive electrode 1312 with spring clip 140 eliminates the need for a connector, significantly reducing the additional size and weight of functional device 12. It also eliminates the effect of the connector opening on the shape of disc rim bend 11, making it more consistent with the standard transmission disc rim bend 11 shape.
